CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a U.S. National Phase Application of PCT/CN2017/116644, filed Dec. 15, 2017, which claims the benefit of priority to CN Application No. 201710055871.7, filed Jan. 25, 2017, and to CN Application No. 201710301497.4, filed May 2, 2017, the contents of which are hereby expressly incorporated by reference in their entirety. 
     TECHNICAL FIELD 
     The disclosure relates to the technical field of air conditioners, and in particular to an air conditioner indoor unit. 
     BACKGROUND 
     At present, an indoor unit of a separated wall-type air conditioner usually has numerous and miscellaneous types of parts, so the production efficiency of general assembly is low. 
     At present, an indoor unit of a separated wall-type air conditioner usually has numerous and miscellaneous types of parts, so the production efficiency of general assembly is low. An existing air conditioner indoor unit includes a bottom shell part, a motor, a motor pressure plate, an electrical box, a fan blade, an evaporator, a panel body, a filter screen, a panel, an air guide plate, and other main structures. There are many structural forms. On a general assembly line, taking the bottom shell part as a basic part, the fan blade and the motor are fixedly connected through a screw, and then mounted above the bottom shell part together. The motor is fixed by using the motor pressure plate. Then, the evaporator is mounted. Because a pipe of the evaporator is at a back side of a base part, it is needed to first break off the pipe of the evaporator, and install the evaporator on the bottom shell part, and then, the pipe is broken back, and the pipe and the evaporator are fixed. Meanwhile, because of a structural limit of the evaporator, it is needed to add tooling in an operating direction of the assembly line to support the base part to a height, so as to conveniently place the pipe of the evaporator. And then, the electrical box is mounted; specifically, the electrical box is fixedly mounted at the right side of the evaporator. At last, the panel body, the filter screen, the panel and the air guide plate are assembled. Accordingly, for such an air conditioner indoor unit, in general assembly, it is needed to assemble in order the above numerous and miscellaneous parts on the general assembly line. The general assembly line is comparatively long, occupies a large space, and has a low general assembly efficiency. 
     Moreover, when the air conditioner indoor unit is completely mounted, only the air guide plate, the panel and the panel body can be dismounted, so when needing to clean the air conditioner indoor unit, a user can only disassemble the filter screen and the air guide plate to clean simply. However, in a long-term use process of the air conditioner indoor unit, an air duct for air-in and air-out, the fan blade and a water duct for collecting condensed water are very easy to produce dirt. These structures of the above air conditioner indoor unit cannot be dismounted to clean regularly, after a long time, the accumulation of dirt on these structures makes the air conditioner indoor unit become a source of pollution, which influences living environments of users with the operation of the air conditioner, and brings harms to the users. Meanwhile, in a process of overhauling the air conditioner indoor unit, when charged structures like the motor and the electrical box, are overhauled, it is needed to disassemble in order the air guide plate, the panel and the panel body according to a reverse order of assembly; at the same time, the process requires a professional to operate, which causes a high cost of cleaning the complete appliance, and requires much time and effort. 
     SUMMARY 
     Therefore, the technical problem to be solved by the disclosure is to overcome the defects of the air conditioner indoor unit in the conventional art that the general assembly efficiency is low, and inconvenient disassembly increases the difficultly of cleaning and overhaul, and provide an air conditioner indoor unit which is high in the general assembly efficiency, convenient and easy to be dismounted, and easy to be cleaned and overhauled.

     a. Each part in the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module as claimed in claim  1  is assembled on a corresponding pre-assembly line, so that the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module form five independent pre-assembly modules respectively. 
     b. On a general assembly line, the base module is taken as an assembling basis, the heat exchange module and the air and water duct module are respectively assembled with the base module. 
     c. The panel body of the shell module as claimed in claim  2  is assembled with the base module, and the filter screen of the shell module is assembled with the panel body of the shell module; then, the air outlet frame module is assembled with the base module, and the panel is assembled with the panel body. 
     d. At last, the air guide module is assembled with the base module, and the assembly of the whole body of the air conditioner indoor unit is completed. 
     Another method for assembling an air conditioner indoor unit of the disclosure includes the following operations. 
     a. Each part in the base module, the air and water duct module, the heat exchange module, the shell module, the air outlet frame module and the air guide module as claimed in claim  1  is assembled on the corresponding pre-assembly line, so that the base module, the air and water duct module, the heat exchange module, the shell module, the air outlet frame module and the air guide module form six independent pre-assembly modules respectively. 
     b. On the general assembly line, the base module is taken as the assembling basis, the heat exchange module and the air and water duct module are respectively assembled with the base module at first. 
     c. The shell module and the air outlet frame module are respectively assembled with the base module. 
     d. The air guide module is assembled with the base module, and the assembly of the whole body of the air conditioner indoor unit is completed. 
     At Step b, one side, arranged with the motor bracket, of the base module is upwards installed on the assembly line; the heat exchange module is assembled on the base module from top to bottom, and after assembly, an opening of a chamber between the back plate of the base module and the heat exchanger faces to a predetermined direction; after that, the air and water duct module is assembled in the part assembled at Step b along the predetermined direction to which the opening of the chamber between the back plate of the base module and the heat exchanger faces. 
     At Step b, a guide rail base of a second guide rail structure as claimed in claim  14  is mounted on the base part at first; and then the air outlet frame module is mounted on the base module through a second guide rail structure. 
     At Step d, after the air outlet frame module is mounted, the air guide module is mounted at an air outlet which is on the air outlet frame. 
     The technical solutions of the disclosure have the following advantages. 
     1. When the air conditioner indoor unit provided by the disclosure is assembled, the base module, the heat exchange module and the air and water duct module may be pre-assembled respectively, and each module is generally assembled after the pre-assembly is completed. In such a manner, the time needed to assemble the whole body is greatly reduced, the assembly efficiency is improved, and the manpower and material cost is saved; moreover, a foundation is laid for the subsequent realization of mechanized and automated production. Meanwhile, when the air conditioner indoor unit is disassembled, the base module, the air and water duct module and the heat exchange module may also be disassembled by taking the module as a unit. In such a manner, the disassembly efficiency may be greatly improved, and convenience is brought to cleaning or maintaining, and replacing a certain structure of the air conditioner indoor unit. Meanwhile, the fan motor is mounted in the base part of the base module, the air duct assembly is arranged in the air and water duct module, and the whole body of the air duct assembly is suitable to be disassembled from the base part without disassembling the fan motor in the base part. On one hand, the fan motor may be directly assembled and disassembled, so as to overhaul and replace the fan motor; on the other hand, when needing to clean the air duct assembly, separating the air duct assembly and the fan motor may directly disassemble the air duct assembly to clean. Compared with the problem in the conventional art that the air duct assembly cannot be cleaned due to arranging the air duct assembly on the bottom shell of the base part, or the performance of the fan motor is influenced by wetting when the air duct assembly is cleaned caused by fixedly mounting the fan motor on the bottom shell which is mounted with the air duct assembly, the disclosure can not only clean the air duct assembly, but also separate the air duct assembly from the fan motor when disassembling the air duct assembly from the base module, thereby preventing the fan motor from being damaged by wetting. In addition, compared with that, in the conventional art, the connection pipeline is bent to the back of the base part, and the heat exchanger of the heat exchange module and the connection pipeline are on different sides of the base module, the heat exchanger of the heat exchange module and the connection pipeline of the disclosure are entirely on the front side of the base module. In such a manner, when the heat exchanger is mounted, a working process of bending the connection pipeline is reduced, and convenience is brought to assembling and disassembling the heat exchange module. 
     2. When the air conditioner indoor unit provided by the disclosure is assembled, the shell module may be pre-assembled at the same time with the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module, and then generally assembled with the above five modules after the pre-assembly is completed. Or, the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module are pre-assembled at first, and then the parts of the shell module are generally assembled with the above five modules on the general assembly line. Any mounting way includes the pre-assembly of the five modules, so the time needed to assemble the whole body is greatly reduced, the assembly efficiency is improved, and the manpower and material cost is saved; moreover, a foundation is laid for the subsequent realization of mechanized and automated production. Meanwhile, when the air conditioner indoor unit is disassembled, at least the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module may be disassembled by taking the module as a unit. In such a manner, the disassembly efficiency may be greatly improved, and convenience is brought to cleaning or maintaining, and replacing a certain structure of the air conditioner indoor unit. Moreover, in design, each structure in the air conditioner indoor unit may be designed in a form of the six modules, namely the base module, the air and water duct module, the heat exchange module, the air outlet frame, the air guide module and the shell module, thereby simplifying a product design process of designers, and improving the design efficiency.

Compared with the problem in the conventional art that the air duct and the water duct cannot be cleaned due to arranging the air duct and the water duct on the bottom shell of the base part, the disclosure may clean the air duct and the water duct better. 
     8. In the air conditioner indoor unit provided by the disclosure, the connection pipeline has a liquid inlet pipe and an air collection pipe. Both the liquid inlet pipe and the air collection pipe are connected on one side, far away from the motor bracket, of the heat exchanger.

     10. Through the method for assembling the air conditioner indoor unit provided by the disclosure, each part in the base module, the heat exchange module and the air and water duct module is pre-assembled, so that the base module, the heat exchange module and the air and water duct module form three independent pre-assembled modules, and then the base module is taken as the assembling basis, the heat exchange module and the air and water duct module are respectively assembled with the base module. In such a manner, the time needed to assemble the whole body is greatly reduced, the assembly efficiency is improved, and the manpower and material cost is saved; moreover, a foundation is laid for the subsequent realization of mechanized and automated production. 
     11. Through the method for assembling the air conditioner indoor unit provided by the disclosure, each part in the base module, the air and water duct module, the heat exchange module, the shell module, the air outlet frame module and the air guide module are pre-assembled on the corresponding pre-assembly line, so that the base module, the air and water duct module, the heat exchange module, the shell module, the air outlet frame module and the air guide module form six independent pre-assembly modules respectively; on the general assembly line, taking the base module as the assembling basis, the heat exchange module and the air and water duct module are respectively assembled with the base module at first; then, the shell module and the air outlet frame module are respectively assembled with the base module; at last, the air guide module is assembled with the base module, so the assembly of the whole body of the air conditioner indoor unit is completed. In such a manner, the general assembly line is greatly shortened, and by pre-assembling the six modules at the same time, the time needed to assemble the whole body is greatly reduced, the assembly efficiency is improved, and the manpower and material cost is saved; moreover, a foundation is laid for the subsequent realization of mechanized and automated production. 
     12. Through the method for assembling the air conditioner indoor unit provided by the disclosure, each part in the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module are pre-assembled on the corresponding pre-assembly line, so that the base module, the air and water duct module, the heat exchange module, the air outlet frame module and the air guide module form five independent pre-assembly modules respectively; on the general assembly line, taking the base module as the assembling basis, the heat exchange module and the air and water duct module are respectively assembled with the base module at first; then, the panel body of the shell module is assembled with the base module, and the filter screen is assembled with the panel body; and then, the air guide module is assembled with the base module, and the panel is assembled with the panel body; at last, the air guide module is assembled with the base module, and the assembly of the whole body of the air conditioner indoor unit is completed.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The technical solutions of the disclosure will be described clearly and completely below in combination with the drawings. Apparently, the described embodiments are merely a part of the embodiments of the disclosure, not all of the embodiments. On the basis of the embodiments of the disclosure, all other embodiments obtained on the premise of no creative work of those skilled in the art fall within the protection scope of the disclosure. 
     In addition, the technical features involved in different implementation modes of the disclosure described below may be combined without conflicts. 
     Embodiment 1 
     As shown in  FIG.  1   , the embodiment provides an air conditioner indoor unit, which includes: a base module i 100 , a heat exchange module i 200 , an air and water duct module i 300  and an exterior module i 400 . 
     The base module i 100  is configured to be mounted on a hanging support body such as an indoor wall, is also used as a basic part for assembly on a production line. As shown in  FIG.  2   , the base module i 100  includes a base part i 101  which is suitable to be mounted on a support. 
     An electric assembly is detachably mounted on the base part i 101 . The electrical assembly includes a fan motor i 141 , and an air guide poking box i 102  and an electrical box i 172  which are detachably mounted on the base part i 101  respectively. In such a manner, the electric assembly may be disassembled directly to be overhauled and replaced. The specific mounting position of the electric assembly on the base part i 101  may have a variety of situations. In the embodiment, the electric assembly is detachably mounted on one end of the base part i 101 , and then, when needing to be overhauled or replaced, the electric assembly may be directly disassembled from the end of the base part i 101 ; so it is very convenient to overhaul and replace the electric assembly. 
     In the embodiment, the electrical assembly further includes a concentrator i 104 . Each load terminal of the air conditioner indoor unit is electrically connected with the concentrator i 104 . The concentrator i 104  is electrically connected with the electrical box i 172 . The concentrator i 104  is first connected with each load terminal of the air conditioner indoor unit, and then connected with the electrical box i 172 . Compared with directly connecting each load terminal of the air conditioner indoor unit with the electrical box i 172 , the connection line between the concentrator i 104  and the electrical box i 172  and the connection line between each load terminal of the air conditioner indoor unit and the electrical box i 172  are much simpler, so convenience is brought to assembling and disassembling the electrical box i 172 , and overhauling and replacing the electrical box i 172 . 
     The electrical box i 172  and the mating concentrator i 104  are arranged close to the end of the base part i 104 . The electrical box i 172  is closer to the end compared with the concentrator i 104 , and the electrical box i 172  is detachably mounted on the base part i 101 . When needing to be overhauled or replaced, the electrical box i 172  may be directly disassembled from the end of the base part i 101  conveniently. 
     The air guide poking box i 102  is arranged at the position, corresponding to the air guide module i 430 , on the base part i 101 . 
     One or two or three of a power cord, an electrical wire of each electrical load and a connection signal wire of an air conditioner indoor unit and an air conditioner outdoor unit may be fixedly arranged on the base part i 101  through a wiring slot fixed on the base part i 101 . In the embodiment, the power cord, the electrical wire of each electrical load and the connection signal wire of the air conditioner indoor unit and the air conditioner outdoor unit are fixedly arranged on the base part i 101  through the wiring slot fixed on the base part i 101 . 
     The base module i 100  further includes a motor bracket fixed on the base part i 101 . The motor bracket includes a motor stand, and a motor pressure plate i 112  and a motor cover plate i 113  which are mounted on the motor stand and configured to fix the fan motor i 141 . The motor pressure plate i 112  and the motor cover plate i 113  are detachably mounted on the base part i 101  respectively. The motor pressure plate i 112  limits the fan motor i 141  in a radial direction, and the motor cover plate i 113  limits the fan motor i 141  in an axial direction When mounted, the fan motor i 141  is limited in a radial direction and an axial direction through the motor pressure plate i 112  and the motor cover plate i 113 . When the fan motor i 141  needs to be overhauled or replaced, the cover plate i 113  of the fan motor i  141  may be disassembled directly, and then the fan motor i 141  is disassembled along the axial direction, so the operation is simple and convenient. 
     Referring to  FIG.  3   , the heat exchange module i 200  is movably mounted on the base module i 100 , and has a heat exchanger i 220  and a connection pipeline for connecting the heat exchanger i 220  to the air conditioner outdoor unit. The heat exchanger i 220  and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger i 220  module and the connection pipeline are entirely at the same side of the base module i 100 . Compared with that, in the conventional art, the connection pipeline is bent to the back of the base part i 101 , and the heat exchanger i 220  of the heat exchanger i 220  module and the connection pipeline are on different sides of the base module i 100 , the heat exchanger i 220  of the heat exchanger i 220  module and the connection pipeline of the disclosure are on the same side of the base module i 100 . In such a manner, when the heat exchanger i 220  is mounted, a working process of bending the connection pipeline is reduced, and convenience is brought to assembling and disassembling the heat exchange module i 200 . There are multiple ways of mounting the heat exchange module i 200  with the base module i 100 . In the embodiment, the heat exchange module i 200  is detachably mounted on the base module i 100  through a hanging structure and a threaded connecting piece. As a transformable implementation mode, the heat exchange module i 200  may also be detachably on the base module i 100  through a buckle structure and the threaded connecting piece. 
     The connection pipeline has a liquid inlet pipe i 2231  and an air collection pipe i 2232 . In the embodiment, in order to save space, both the liquid inlet pipe i 2231  and the air collection pipe i 2232  are connected on one side, far away from the motor bracket, of the heat exchanger i 220 . There are tee structures arranged on both the liquid inlet pipe i 2231  and the air collection pipe i 2232 ; with the tee structure, both sides of the heat exchanger i 220  are arranged with an outdoor unit connection terminal of the connection pipeline. In such a manner, during the actual installation of the air conditioner indoor unit, it is convenient for the installation personnel to select, according to the actual situation of the user, a connection end of the connection pipeline at one end of the heat exchanger i 220  to be connected with the air conditioner outdoor unit, thereby saving the space occupation of installation, and improving the installation efficiency. As a transformable implementation mode, both the liquid inlet pipe i 2231  and the air collection pipe i 2232  may also be connected on one side, close to the motor bracket, of the heat exchanger i 220 . 
     After the liquid inlet pipe i 2231  and the air collection pipe i 2232  pass through the tee structure, one branch forms a U-shaped bend which bypasses the motor bracket from the side, far away from a back plate of the base part i 101 , of the motor bracket after extending beyond the length of the heat exchanger i 220  at a position close to the back plate of the base part i 101 , reaches a lower edge of the back plate of the base part i 101  in a working and mounting state, and bends, at the position close to the back plate of the base part i 101 , towards an end of the base part i 101  on this side; another branch after the liquid inlet pipe i 2231  and the air collection pipe i 2232  pass through the tee structure extends to the lower edge of the back plate of the base part i 101  in the working and mounting state on this side, and bends, at the position close to the back plate of the base part i 101 , towards the end of the base part i 101  on this side. 
     In the embodiment, a cross section of the heat exchanger i 220  is inverted-U shaped, and its two sides are arranged with a hanging fixing structure for mounting the heat exchanger i 220  on the base module i 100  in a hanging way; two ends of the heat exchanger i 220  are arranged with a sealing part i 221 , so that an open chamber is formed in the inverted-U shaped interior of the heat exchanger i 220 ; an angular frame i 210  is fixed on the heat exchanger i 220 , and a fixing structure for fixing the connection pipeline is arranged on the angular frame i 210 . 
     Referring to  FIG.  4   , the air and water duct module i 300  is movably mounted on the base module i 100 , and has a bottom shell i 310  and an impeller i 320  which is rotationally mounted on the bottom shell i 310 . An impeller shaft of the impeller i 320  is suitable to be, by means of a quick disconnecting and connecting mechanism, connected to and separated from an output shaft of the fan motor i 141  through a position movement between them. There can be various specific ways of mounting the air and water duct module i 300  with the base module i 100 . In the embodiment, the air and water duct module i 300  is mounted on the base module i 100  in a sliding manner through a first guide structure, and its mounted state is limited and locked through the buckle structure and the threaded connecting piece. The first guide structure in the embodiment is a first sliding structure. As a transformable implementation mode, the first guide structure may also be a first guide rail structure. 
     In the embodiment, both an air duct and a water duct of the air conditioner indoor unit are formed on the bottom shell i 310  of the air and water duct module i 300 . The air duct and the water duct are arranged on the bottom shell i 310  of the air and water duct module i 300 , when the air duct and the water duct need to be cleaned, the air and water duct module i 300  may be directly disassembled to clean the air duct and the water duct.

     The modules are respectively described below. 
     Embodiment 2 
     A modular air conditioner includes a base module, a heat exchange module, an air duct part and an exterior module. 
     As shown in the drawings  FIG.  7    to  FIG.  15   , the base module is configured to be mounted on a hanging support body such as an indoor wall, is also used as a basic part for assembly on a production line. The base module includes a base part g 330  suitable to be mounted on the support body, a motor bracket fixedly arranged on the base part g 330 , a motor assembly and an electrical control part. 
     The motor bracket is arranged at a position close to one end of the base part g 330  in a length direction, and an axis of an output shaft of a supported motor g 220  extends in the length direction of the base part g 330 . In the embodiment, the motor bracket consists of a motor stand d 51 , a motor pressure plate g 250  and a motor end cover. 
     The motor stand d 51  is formed integrally with the base part g 330  by, for example, injection molding. The motor pressure plate g 250  is fastened to the motor stand d 51  and fixed by screws to limit movement of the motor g 220  in the motor assembly in a radial direction of a rotating shaft and form a chamber for accommodating and circumferential embracing the motor g 220  in the motor assembly. The side, close to an adjacent end portion of the base part g 330 , of the chamber forms a mounting end that allows the motor g 220  to be axially embedded into and withdrawn from the chamber, and the side far away from the end portion of the base part g 330  forms a limiting end that limits further movement of the motor g 220  embedded into the chamber towards the end portion, from which it is far away, of the base part g 330 . The motor end cover g 240  may be fixedly mounted at the mounting end to limit movement of the motor g 220  mounted in the chamber towards a direction of withdrawal from the chamber, as shown in  FIG.  2   . 
     In the embodiment, the electrical control part includes an electrical box r 172  in which a main board and other control elements such as a transformer are placed together. The electrical box r 172  is inserted into the base part g 330  through two horn buckles at a bottom end, and then is detachably fixed on the base part g 330  in a screw fixing manner. An internal structure of the electrical box r 172  is fixedly provided with the main board. A terminal board of the electrical box r 172  is fixed in the electrical box r 172  in parallel with the main board. The main board is mounted in the electrical box r 172  in a state of being perpendicular to the axis of the output shaft of the motor g 220 . For avoiding mechanical interference between the electrical box r 172  and another part on a path of moving out of the base part g 330  in an axial direction of the output shaft of the motor g 220 , the electrical box r 172  is designed with a stepped contour according to a through section on the path. In addition, the internal structure of the electrical box r 172  is designed with lug bosses. The lug bosses are arranged to avoid the external motor assembly on one hand and, on the other hand, strength structural strength of the electrical box r 172 . Each component of the main board is mounted with one side facing an inner side of the electrical box r 172 , so that the components of the main board may be arranged by full use of spaces between multiple lug bosses, and a structural form of the electrical box r 172  is more advantageous in space occupation. 
     Besides the motor g 220 , the motor assembly further includes an extension and retraction motor, air guide motor and air sweeping motor poking an air guide module in the exterior module to act. In the embodiment, a pair of air guide poking boxes are fixedly mounted on two sides of the base part g 330  in the length direction, the air guide poking box on the side far away from the motor bracket is fixed on a bracket structure on the corresponding side of the base part g 330  by screws, and the air guide poking box on the side close to the motor bracket is clamped on the motor bracket through a buckle at a bottom end and fixed by screws. A connecting rod assembly is arranged in each air guide poking box in a sliding manner, and a head of the connecting rod assembly telescopically extends out along an extension opening on one side of the air guide poking box. The air guide motor includes the extension and retraction motor arranged on the air guide poking box, an air guide motor arranged at a head end of the connecting rod assembly on one side and the air sweeping motor arranged at a head end of the connecting rod assembly on the other side. The connecting rod assembly is connected with an output shaft of the extension and retraction motor through a gear and rack mechanism. An output shaft of the air guide motor drives an air guide plate, and an output shaft of the air sweeping motor drives an air sweeping plate. Wires connected with the air guide motor and the air sweeping motor penetrate through the corresponding connecting rod assemblies respectively. 
     Electrical wires connecting each load, such as an electrical component like a display, the motor, a wifi box and a cold plasma, in an indoor unit are fixedly arranged on the base part g 330  through a wiring slot fixedly formed in the base part g 330 . The other end of each electrical wire is connected to a concentrator, and is electrically connected with the electrical box r 172  through the concentrator in a pluggable manner. The concentrator is inserted into a limiting hole in the base part g 330  through a horn buckle at the bottom end, and then is fixed on the base part g 330  or the motor pressure plate g 250  by screws. A pin interface is formed in the concentrator, a connecting pin is arranged at a mounting position corresponding to the pin interface on the electrical box r 172 , a line concentration box is arranged at the corresponding connecting pin in the electrical box r 172 , and terminal blocks, corresponding to each electrical component load, of the main board are arranged in the line concentration box in a centralized manner. Arrangement of the line concentration box corresponding to the concentrator in the electrical box r 172  is favorable for centralized wiring and bundling of the component wires, and thus the electrical box r 172  may be disassembled as an independent structure. The concentrator mates with the electrical box r 172  through a limiting rib and the limiting hole. Devices corresponding to high voltage and devices corresponding to low voltage are regionally arranged in the electrical box r 172  to reduce interference between each electrical device. 
     The electrical box r 172 , as an electrical control portion of the air conditioner, is a frequently disassembled part of the air conditioner, and whether it is mounted in place or not is crucial for whether the air conditioner may be used normally or not. In the embodiment, a mounting protection function for the electrical box r 172  is set to implement error reporting control and prompting for whether the electrical box r 172  is butted with the contractor well or not by logical control if the condition that the patch panel in the contractor and the main board in the electrical box r 172  are disconnected and not connected in place occurs when the electrical box r 172  is butted with the concentrator. 
     A logical control function is analyzed as follows: when the electrical box r 172  or the concentrator is not mounted in place to cause an air conditioner indoor unit to fail at a control function end, disconnection or not-in-place connection is detected, and if it is detected after maintenance that the air conditioner works normally, maintenance work is finished. 
     The mounting protection function for the electrical box r 172  is designed and developed to ensure that the electrical box r 172  is mounted in place and improve a modular design degree of the air conditioner. 
     In addition, finned rib plates, i.e., a water retaining rib plate and a pipe retaining rib plate, are designed on two sides of the motor pressure plate g 250  respectively. A connecting pipeline of a heat exchanger is arranged through a horizontal slot between the two finned rib plates, so that leftward and rightward collision of the connecting pipeline of the heat exchanger is limited, and the phenomenon that the air guide poking boxes are collided and further dislocated to affect extension and retraction accuracy of the air guide plate is avoided. Meanwhile, the water retaining rib plate guides condensed water on the heat exchanger to a bottom shell to realize a water guide function. 
     The finned rib plates close to the two sides of the motor pressure plate g 250  are both provided with screw mounting columns, the motor pressure plate g 250  mates with a pipe pressure plate, and the pipe pressure plate is fixed on the motor pressure plate g 250  by mating of screws and the screw mounting columns to firmly fix the connecting pipeline of the heat exchanger in the horizontal slot formed between the two finned rib plates on the motor pressure plate g 250  and fix the connecting pipeline of the heat exchanger in a direction perpendicular to a wall surface. The motor pressure plate g 250  has a function of arranging the pipeline and limiting the pipeline. The connecting pipeline of the heat exchanger is arranged on the motor pressure plate g 250 , so that a utilization rate of an internal space of the air conditioner is increased. Meanwhile, a wiring clamping groove for the loads is arranged on the pipe pressure plate, so that more standard and reasonable wiring in the air conditioner is ensured. 
     During assembling, screw holes in the motor bracket and the motor pressure plate g 250  are aligned, and the motor pressure plate g 250  is fixed on the motor bracket by screws. The connecting pipeline of the heat exchanger is placed in the horizontal slot between the two finned rib plates of the motor pressure plate g 250 . The finned rib plates not only have a function of guiding the condensed water on the heat exchanger into a drainage system on the bottom shell but also have a function of limiting the connecting pipeline of the heat exchanger. The finned rib plates further have both the function of limiting the connecting pipeline of the heat exchanger and a collision prevention function: during transportation or a drop test, the connecting pipeline of the heat exchanger may sway leftwards and rightwards, and the finned rib plates limit leftward and rightward sway thereof to avoid the phenomenon that the connecting pipeline of the heat exchanger collides and further dislocates the air guide poking boxes to affect the extension and retraction accuracy of the air guide poking boxes poking the air guide plate to cause vibration or inclination of the air guide plate during running. In the embodiment, the motor pressure plate g 250  implements arrangement of the connecting pipeline at an upper portion of the motor pressure plate g 250 , and mates with the pipe pressure plate to limit movement of the connecting pipeline of the heat exchanger in the direction perpendicular to the wall surface and optimize an occupation rate of the internal space of the air conditioner. 
     The screw mounting columns are designed on the motor pressure plate g 250  for firm fixation and also for fixation of the pipe pressure plate, so that movement of the connecting pipeline of the heat exchanger in the direction perpendicular to the wall surface is limited. 
     The base part g 330  is provided with a wiring slot and wiring buckles corresponding to a poking module wire and an ambient temperature wrap wire. Specifically, during mounting on a production assembling line, the ambient temperature wrap wire, after being led out of the concentrator, is placed in the wiring slot shown in  FIG.  1    at first, and the ambient temperature wrap wire is clamped with a fifth buckle d 55 , a sixth buckle d 56  and a seventh buckle d 57 ; and a poking box wire on a left side, after being led out of the concentrator, is clamped into the wiring slot, and the left poking box wire is clamped with a first buckle d 50 , a second buckle d 52 , a third buckle d 53 , a fourth buckle d 54 , the fifth buckle d 55 , the sixth buckle d 56  and the seventh buckle d 57 , to complete wiring arrangement on the base, as shown in  FIG.  11   . 
     In the embodiment, the base is movably connected with an air outlet frame of an air outlet assembly d 42  of the air conditioner through a sliding rail device d 52  to enable the air outlet assembly d 42  to slide out of the base along the sliding rail device d 52 , so that the air outlet assembly d 42  may be conveniently disassembled and cleaned. 
     Specifically, the sliding rail device d 52  includes a sliding rail base vertically fixed on the base in a working state, a sliding rack mounted in a sliding chute of the sliding rail base in the sliding manner and a sliding rail end rod of which one end is fixedly mounted on the sliding rack, the other end of the sliding rail end rod being fixedly connected with the air outlet frame. A clamping hook is formed on the sliding rail end rod, and the clamping hook is connected with a clamping groove formed in the air outlet frame in an inserting and mating manner, as shown in  FIG.  8    and  FIG.  15   . 
     To conveniently disassemble and assemble the air duct part, the mounting structure includes a limiting structure formed on the base to limit the air duct assembly in the working state in a vertical direction and a direction perpendicular to the base and sliding bridge structures d 46  configured to guide the air duct assembly to slide into a base mounting position. Making the air duct part slide out along the sliding bridge is convenient to clean the air duct part, as shown in  FIG.  9    and  FIG.  10   . 
     The limiting structure includes limiting hooks d 44  which are formed on a back plate of the base part g 330  in columns on left and right and of which opening directions are consistent with an opening direction of the open chamber, first limiting stages d 47  and second limiting stages d 48  formed in columns on left and right and corresponding to a bottom shell lower edge of the bottom shell of the air duct part, embedded pieces d 44  fixedly arranged at an upper portion of the bottom shell and correspondingly suitable to be embedded into the limiting hooks d 44  after being mounted along the open chamber, second fixing holes suitable to support the bottom shell lower edge of the bottom shell on the two limiting stages when the embedded pieces are embedded into the limiting hooks d 44 , formed in columns on left and right in a lower portion of the bottom shell and axially perpendicular to the back plate of the base part g 330 , second screw holes formed in the base part g 330  and corresponding to the second fixing holes at a mounting position of the bottom shell and second screws configured to penetrate through the second fixing holes to form screwed connection with the second screw holes, as shown in  FIG.  14   . 
     In the embodiment, the mounting structure further includes an indication structure d 45  arranged at a position corresponding to a bottom shell side edge of the air duct assembly on the base and mating with the bottom shell side edge to assist in-place positional assembling. Specifically, the indication structure d 45  is a buckle structure, the buckle structure functions to assist in-place positional assembling, and during disassembling or assembling, a sound “Da” represents that the bottom shell has been arranged in place. The limiting stages arranged in columns on the lower edge of the bottom shell have a lifting function, and may prevent the air duct part from sliding off after screws on sliding bridges are disassembled. During disassembling, the air duct part is slightly lifted in the direction perpendicular to the wall surface to separate the air duct assembly from the two limiting stages, and the air duct part is manually pulled to slide downwards along the sliding bridges to complete disassembling, as shown in  FIG.  10   .

In such a manner, it is ensured that the motor g 220  may run normally and stably at the working position; and meanwhile, when the motor g 220  requires after-sales maintenance, it is only necessary to release limiting of the limiting assembly in the motor assembly and implement quick release of the motor shaft and the fan blade shaft in the air conditioner through the quick release connecting structure, then the motor g 220  may be directly taken out of the air conditioner, and since it is unnecessary to disassemble the motor shaft and the fan blade shaft and screw the screws in the air conditioner, time and labor are saved, and the after-sales service cost and time are reduced. 
     As shown in  FIG.  45    and  FIG.  46   , specifically, the quick release connecting structure in the embodiment of the disclosure includes a clamping claw arranged on the motor shaft and a clamping groove correspondingly formed in the fan blade shaft in the air conditioner and mating with the clamping claw. At the working position of the motor g 220 , the clamping claw on the motor g 220  in the motor assembly extends into the clamping groove, and the motor shaft rotates to drive the fan blade shaft to rotate. At the quick release position of the motor g 220 , when the motor g 220  is disassembled after the motor g 220  is unlocked, the clamping claw is extracted from the clamping groove, and then the motor g 220  may be quickly disassembled for subsequent maintenance. It can be understood that the quick release connecting structure may also include a clamping groove formed in the motor shaft and a clamping claw correspondingly arranged on the fan blade shaft and mating with the clamping groove, and the purpose of quickly disassembling and connecting the motor shaft and the fan blade shaft may also be achieved. 
     Preferably, in the embodiment of the disclosure, the clamping claw arranged on the motor shaft in the motor assembly is a helical clamping claw g 361 , and the corresponding clamping groove is a helical clamping groove g 370 , so that the motor shaft may rotate at the working position of the motor g 220  to make the helical clamping claw g 361  and the helical clamping groove g 370  get close to each other under the action of a helical surface, the motor shaft and the fan blade shaft are unlikely to separate in a rotating process, and it is ensured that the motor g 220  at the working position may run stably. 
     Specifically, in the embodiment of the disclosure, the helical clamping claw g 361  is arranged on a motor shaft sleeve g 311 , the motor shaft sleeve g 311  is mounted on the motor shaft, motor shaft sleeve mounting holes are formed in both the motor shaft sleeve g 311  and the motor shaft, and the motor shaft sleeve g 311  and the motor shaft may be detachably mounted through screws penetrating through the motor shaft sleeve mounting holes. In a transformed embodiment not shown in the figures, the motor shaft sleeve g 311  is formed integrally with the motor shaft. 
     Preferably, in the embodiment of the disclosure, the motor stand g 210  is formed integrally with the base part g 330  of the motor assembly. More specifically, the motor stand g 210  and the base part g 330  are formed integrally in an injection molding manner. Therefore, the motor stand g 210  is not required to be manufactured and mounted independently in a production and manufacturing process of the air conditioner, manufacturing efficiency of an air conditioner product is improved, and meanwhile, abnormal noises, caused by improper mounting of the motor stand g 210  and the base part g 330 , of the air conditioner in a using process may be avoided. 
     Specifically, for the limiting assembly configured to implement stable running of the motor assembly at the working position in the embodiment, the limiting assembly in the embodiment includes: a motor pressure plate g 250 , configured to mate with the motor stand g 210  to limit the motor g 220  in a radial direction of the motor g 220 ; and a motor end cover, configured to mate with the motor stand g 210  to laterally limit the motor g 220  in an axial direction of the motor g 220 . Therefore, the motor g 220  may be limited in multiple directions, and movement stability of the motor g 220  at the working position is ensured. 
     Therefore, when the motor g 220  in the embodiment is maintained and serviced, a side panel in the air conditioner and the motor end cover configured to laterally limit the motor g 220  are disassembled at first, and then the motor pressure plate g 250  is disassembled after the screws fixing the motor pressure plate g 250  are disassembled. Due to existence of a helical structural form of the motor shaft sleeve g 311 , the motor g 220  may be quickly separated from the fan blade shaft at the quick release position, and in such case, the motor g 220  may be manually pulled rightwards to be disassembled. 
     Then, the wiring structure in the air conditioner of the embodiment of the disclosure will be elaborated according to the drawings. 
       FIG.  29    is a structure diagram of a motor pressure plate. The motor pressure plate includes a pressure plate body c 1 . The side, facing the motor, of the pressure plate body c 1  has a mating structure mating with the motor. The motor pressure plate mates with the motor stand to fix the motor. A first reinforcing wall c 3  and a second reinforcing wall c 4  are arranged in parallel on the side, back on to the motor, of the pressure plate body c 1 . The first reinforcing wall c 3  and the second reinforcing wall c 4  extend in the same direction and are spaced by a set distance, and a region therebetween is a fixing groove c 5 . A connecting pipe of the heat exchanger is positioned at a top of the motor pressure plate and arranged in the fixing groove c 5  between the first reinforcing wall c 3  and the second reinforcing wall c 4 . 
     Positioning the connecting pipe at the top of the motor pressure plate optimizes mounting positions of the components in the air conditioner and increases the utilization rate of the internal space of the air conditioner. Formation of the fixing groove c 5  may effectively prevent leftward and rightward collision of the connecting pipe and avoid the phenomenon that poking modules are collided and further dislocated to affect the extension and retraction accuracy of the air guide plate. 
     The condensed water may be produced on a surface of the heat exchanger in a working process. The first reinforcing wall c 3  is a water retaining structure configured to guide the condensed water on the heat exchanger to a water groove on the bottom shell to facilitate water groove and realize a flow guide function. 
     The motor pressure plate and the motor stand are integrally formed by an integration process respectively, for example, casting forming and injection molding. 
     According to the above descriptions, it can be seen that the first reinforcing wall c 3  not only has a water guide function of guiding the condensed water on the heat exchanger into the water groove on the bottom shell but also has the function of limiting the connecting pipe. The second reinforcing wall c 4  not only has the function of limiting connecting pipe but also may have the collision prevention function. During transportation or a drop test, the connecting pipe of the heat exchanger may sway leftwards and rightwards. The second reinforcing wall c 4  limits leftward and rightward sway of the connecting pipe. 
     Compared with a motor pressure plate in the conventional art, the motor pressure plate in the application is not only endowed with additional functions and functionally diversified, but also fully uses the internal space of the air conditioner, increases the occupation rate of the internal space of the air conditioner and achieve higher adaptability to a modular design requirement of the air conditioner. 
     As a transformable embodiment, the fixing groove includes a first fixing groove and a second fixing groove formed corresponding to the connecting pipe respectively. That is, three parallel reinforcing walls are arranged on the side, back on to the motor, of the pressure plate body c 1 , and a fixing groove is formed between every two adjacent reinforcing walls. The two fixing grooves correspond to the connecting pipe respectively, and are configured to limit leftward and rightward sway of the connecting pipe respectively. In such an arrangement manner, a relatively good limiting effect may be ensured. 
     As a transformable embodiment, the first reinforcing wall c 3  and a second reinforcing wall c 4  may be substituted with simple protruding structures, and may also be substituted with ordinary platy structures. Extension lengths of the protruding structures or platy structures forming the fixing groove c 5  should be designed based on such a standard that leftward and rightward sway of the connecting pipe may be limited. The reinforcing walls, protruding structures and platy structures forming the fixing groove c 5  are collectively referred to as a first bump and second bump forming the fixing groove c 5 . 
     The pressure plate body c 1  is buckled with a pipe pressure plate corresponding to at top end of the fixing groove c 5 . The pipe pressure plate is fixedly arranged on the pressure plate body c 1 , and is configured to limit the connecting pipe in upward and downward directions, thereby preventing the connecting pipe from being separated from the top end of the fixing groove c 5 . The pressure plate body c 1  mates with the pipe pressure plate to firmly limit the connecting pipe in the fixing groove c 5  of the motor pressure plate. The motor pressure plate and the pipe pressure plate have the function of arranging the pipe and limiting the pipe. 
     From  FIG.  29    and  FIG.  30   , it can be seen that the pressure plate body c 1  is provided with a first mounting hole c 2 . A second mounting hole c 8  corresponding to the first mounting hole c 2  is formed in the pipe pressure plate. When the pressure plate body c 1  and the pipe pressure plate are mounted, the first mounting hole c 2  is opposite to the second mounting hole c 8 , and a first threaded connecting pipe is arranged therein in a penetration manner. Fixed mating of the pipe pressure plate and the pressure plate body c 1  is implemented through the first threaded connecting piece. 
     The pressure plate body c 1  is provided with a third mounting hole c 6  corresponding to a middle frame structure of the air conditioner. The pressure plate body c 1  is connected with the middle frame structure through a second threaded connecting piece arranged in the third mounting hole c 6  in the penetration manner. By such a design, the motor pressure plate further has a function of fixing the middle frame structure, and is more functionally diversified, and the overall reliability is higher. 
     For limiting movement of the connecting pipe in the upward and downward directions in the fixing groove c 5 , as an alternative implementation mode, the fixing groove c 5  includes a first lateral surface and second lateral surface that are opposite to each other, the first lateral surface and/or the second lateral surface are/is provided with a limiting bump corresponding to a top-end position, and an extension direction of the limiting bump is perpendicular to the other lateral surface. The limiting bump is arranged to limit the movement of the connecting pipe in the upward and downward directions in the fixing groove c 5 .

Extension directions of the first side plate and the second side plate are parallel and both perpendicular to the pipe pressure plate body c 7 . The first side plate is a continuous platy structure, and the second side plate includes a first sub-plate and second sub-plate of which extension directions are consistent. An opening of a set distance is formed between the first sub-plate and the second sub-plate. A baffle plate extending towards the second side plate is arranged at a top end of the first side plate. For conveniently assembling and disassembling the load line, the baffle plate is arranged corresponding to a position of the opening. The load line is arranged along a region between the first side plate and the second side plate, and is limited by the baffle plate.

When maintenance is required, the side plate assembly of the air conditioner is disassembled at first, and then the electrical box is pulled out, so that the electrical box is conveniently disassembled. 
     As an extended embodiment of the disclosure, as shown in  FIGS.  35  to  2 - 30   , an air conditioner frame structure includes a back plate d 1  of a base and two side mounting frames d 2 . 
     One side mounting frame d 2  is arranged at one end of the back plate d 1  of the base in a length direction, and the other side mounting frame d 2  is arranged at the other end of the back plate d 1  of the base in the length direction. The side mounting frames d 2  and the back plate d 1  of the base are mounted in a drawable mating manner through a sliding rail structure d 3  that extending in a vertical direction. The sliding rail structure d 3  includes a guide rail d 31  arranged on the side mounting frames d 2  and a guide groove d 32  arranged on the back plate of the base part, as shown in  FIG.  36   . Screw-free assembling is implemented, simple structure and convenience for disassembling are achieved, and assembling and disassembling efficiency is further improved. The guide rail d 31  is arranged close to a side end of the back plate d 1  of the base along the side mounting frames d 2 , and the guide groove d 32  of the back plate d 1  of the base is arranged at a position, corresponding to side ends of the side mounting frames d 2 , of the back plate d 1  of the base. A cross section of the guide rail d 31  is shaped like a Chinese character “Tu”, a cross section of the guide rail d 32 , adapted thereto, is also shaped like the Chinese character “Tu”, and the guide rail d 31  shaped like the Chinese character “Tu” mates with the guide groove d 32  shaped like the Chinese character “Tu” to form a limiting surface d 33  that prevents the side mounting frames d 2  from being separated from a direction perpendicular to the back plate d 1  of the base, as shown in  FIG.  36   . 
     The side mounting frames d 2  are inserted into the back plate d 1  of the base from top to bottom for assembling through the sliding rail structure d 3 , and after assembling, the two side mounting frames d 2  and the back plate d 1  of the base form a basic frame configured to mount air conditioner panels d 10 , a filter screen d 11  and an air outlet frame part.

The side mounting frames d 2  are mounted at the back plate d 1  of the base, the side mounting frame d 2  has a mounting portion for the side panel d 10 , and the mounting portion for the side panel d 10  is detachably connected with the corresponding side panel d 10  through a buckle structure. In the embodiment, structures such as the air conditioner panels d 10 , the filter screen d 11  and the air outlet frame part may be disassembled from the side mounting frames d 2  to clean each component only by lightly pushing the side mounting frames d 2  upwards. After the components such as the panel d 10  and the air outlet frame part are disassembled from the mounting frames, a heat exchanger part mounted in the basic frame may also be exposed, so that the heat exchanger part may be conveniently disassembled and cleaned. In addition, with adoption of such a frame structural form that the back plate d 1  of the base mates with the two mounting frames, a size of the back plate d 1  of the base in a width direction may be reduced to a certain extent, so that a size of a component of the back plate d 1  of the base is reduced. Also, an overall size of a mold is reduced, and cost of the mold is reduced. Meanwhile, using the mounting frames reduces protruding structures on the component of the back plate d 1  of the base, and avoids the phenomenon in a transportation swaying process of an air conditioner that the protruding structures on the component of the back plate d 1  of the base collide with adjacent components to cause structural damages to the air conditioner and a failure of the air conditioner. 
     At least one side mounting frame d 2  in the two side mounting frames d 2  is a frame consisting of a vertical plate d 21  and a transverse plate d 22 , and the transverse plate d 22  is arranged at a top of the vertical plate d 21  and extends towards an inner side of the back plate d 1  of the base in a horizontal direction as a filter screen d 11  support surface that supports the filter screen d 11 . 
     For ensuring firmness of the assembled basic frame structure, in the abovementioned embodiment, the side mounting frames d 2  are fixed with the back plate d 1  of the base through the buckle structure. 
     In the abovementioned embodiment, arrangement positions of the guide rail d 31  and the guide groove d 32  may be substituted in a manner that the guide groove d 32  is arranged at side ends of the side mounting frames d 2  and the guide rail d 31  is arranged at a position, corresponding to the side ends of the side mounting frames d 2 , of the back plate d 1  of the base. 
     In the abovementioned embodiment, the guide groove d 32  shaped like the Chinese character “Tu” and the guide rail d 31  shaped like the Chinese character “Tu” may be substituted into a cylindrical guide groove d 32  and a cylindrical guide rail d 31  or substituted with a rectangular guide groove d 32  and a rectangular guide rail d 31 , and at least one limiting bump that mates with the rectangular guide rail d 31  to prevent the rectangular guide rail d 31  from being separated from the rectangular guide groove d 32  is arranged at the edge, far away from a slot bottom, of the rectangular slot d 32 . Shapes of the guide groove d 32  and the guide rail d 31  are not specifically limited in the disclosure. 
     In the disclosure, a mounting manner of insertion from top to bottom through the guide rail d 31  is preferably adopted for the side mounting frames d 2  and the back plate d 1  of the base. A mounting position of the air conditioner is relatively high, so that the abovementioned embodiment may be substituted in a manner that an insertion direction of the side mounting frames d 2  relative to the back plate d 1  of the base is insertion from the top or insertion from the bottom or insertion from a front end or insertion from an axial outer side of the back plate d 1  of the base in the length direction. It is to be noted that, when the side mounting frames d 2  include the transverse plates d 22 , insertion into the back plate d 1  of the base from the bottom may be subjected to interference of a component on the inner side of the back plate d 1  of the base and thus a mounting manner of insertion from the bottom may not be adopted. 
     As an extended embodiment of the disclosure, as shown in  FIG.  37    and  FIG.  38   , for the problem that it is inconvenient to disassemble a motor assembly in an existing air conditioner for after-sales maintenance, an embodiment of the disclosure provides a motor mounting structure for an air conditioner, which includes a motor assembly. The motor assembly includes a motor stand g 210  arranged on a base part g 330  and a motor g 220  mounted on the motor stand g 210 . A mating structure drawably mating with the base part g 330  is arranged on the motor stand g 210 , and the motor stand g 210  is drawably mounted at the base part g 330  through the mating structure. In such a manner, the motor stand g 210  in the motor assembly of the motor mounting structure may be drawably assembled and disassembled relative to the base part g 330 , and when the motor assembly in the air conditioner requires after-sales maintenance, the motor assembly at a working position is only required to be drawn out of the air conditioner for disassembling after a right side plate g 282  is disassembled, and the motor assembly is not required to be disassembled in the air conditioner, so that difficulties in after-sales maintenance of the motor assembly in the air conditioner are reduced, and after-sales maintenance cost is reduced. 
     The motor mounting structure in the embodiment is more specifically applied to an air conditioner of which a motor shaft and a driven part may be quickly disassembled, for example, an air conditioner of which a motor shaft and a fan blade shaft are quickly connected and disassembled through a helical clamping claw and a helical clamping groove.

       FIG.  73    shows an air conditioner indoor unit of the disclosure. The air conditioner indoor unit includes: a base module  100 , a heat exchange module  200 , an air and water duct module  300  and an exterior module  400 . 
     The air and water duct module  300  includes an air duct assembly  301 , as shown in  FIG.  74   . The air duct assembly has a bottom shell  310 . A fan support  311  is arranged on the bottom shell  310 . There is a centering device arranged between the fan support  311  and the impeller shaft  321  of the impeller  320 . The centering device is a bearing rubber base assembly  330 . One impeller  320  is mounted on the fan support  311 . Specifically, the impeller is arranged, at the side which is close to the fan motor  141  of the impeller shaft  321 , on the fan support  311  of the bottom shell  310  through the bearing rubber base assembly  330 , as shown in  FIG.  91    and  FIG.  96   . 
     As shown in  FIG.  74   , an impeller assembly  3011  in the air duct assembly  301  includes the impeller  320  having the impeller shaft  321 . One end, close to the fan motor  141 , of the impeller shaft  321  is in transmission connection with the fan motor  141 , and another end is rotationally arranged on the bottom shell  310 . The end, close to the fan motor  141 , of the impeller shaft  321 , is also sheathed with the bearing rubber base assembly  330 . The bearing rubber base assembly is suitable to be fixed on the bottom shell  310 . The bearing rubber base assembly  330  provided by the embodiment includes: a support shaft sleeve  332  and a rubber base bracket  331 . The inner loop surface of the support shaft sleeve  332  is sheathed on the outer surface of the impeller shaft  321 . The rotation shaft is in transmission connection with the output shaft of the fan motor  141 . The rubber base bracket  331  is fixedly connect ion with the support shaft sleeve  332 , and is suitable to be fixedly mounted on the support. There is also an impeller bearing  334  arranged between the inner loop surface of the support shaft sleeve  332  and the impeller shaft  321  of the impeller. The support shaft sleeve  332  and the rubber base bracket  331  are formed integrally. The support shaft sleeve is a self-lubricating rubber gasket. A bracket insertion portion  3310  mating with the bottom shell  310  is arranged on the rubber base bracket  331 . The bracket insertion portion  3310  includes: a bracket limiting portion  3311  for limiting an insertion depth with the bottom shell  310 , and a bracket guide portion  3312  mating with the guide structure  3102  on the side wall of the bottom shell  310 . The support shaft sleeve  332  is a self-lubricating elastic rubber gasket. There is also the impeller bearing  334  arranged in the support shaft sleeve  332 . The impeller bearing  334  rotationally mates with the impeller shaft  321 . The bottom shell  310  has a side face facing towards the heat exchange module  200 . A water groove for collecting and draining the condensed water from the heat exchange module  200  is formed on the side face. The impeller  320  is in the water groove after being mounted on the fan support  311 . 
     The bearing rubber base assembly  330  is mounted on the support, and arranged on the end, close to the fan motor  141 , of the impeller  320 , thereby solving the problem of hanging connection between the impeller shaft and a motor output shaft. In the conventional art, when disassembled, the impeller  320  moves towards the direction fay away from the fan motor  141 . The bearing rubber base assembly  330  provided by the embodiment is configured to support the impeller shaft sleeve close to the end of the fan motor  141 , thereby preventing the impeller  320  from damage caused by inclining or dropping in the assembling or disassembling process. That is, after an operator pushes the impeller  320  far away from the fan motor  141  to clean, the impeller  320  may be supported by the bearing rubber base assembly  330 . After the impeller  320  is cleaned, and before the impeller  320  is butted with the fan motor  141 , the impeller  320  is connected with the fan motor  141  in an alignment way by means of the bearing rubber base assembly  330 . The support shaft sleeve  332  is an elastic shaft sleeve, and has a certain elasticity. In the case of misalignment happening when the rotation shaft is butted with the fan motor  141  in the beginning, according to the positions of the rotation shaft and the fan motor  141 , an adaptive adjustment may be made through the elasticity of the support shaft sleeve  332  to counteract the misalignment, thereby reducing the wear of the rotation shaft and the output shaft, and prolonging the service life of the rotation shaft and its products. The rubber base bracket  331  is sheathed on the outer side of the support shaft sleeve  332 , that is, does not interfere with the rotation shaft on the inner loop surface of the support shaft sleeve  332 . The sheathed connection also enables the support shaft sleeve  332  not to move relative to the rubber base bracket  331 . An oil groove is formed on the inner wall of the impeller bearing  334 , so that the space between the inner wall of the impeller shaft  334  and the outer wall of the rotation shaft may be full of lubricating oil, thereby reducing a frictional force in the relative movement of them, and improving the rotation efficiency. The rubber base bracket  331  is fixed on an axial side wall of the support shaft sleeve  332 , and has an axially extending arc-shaped portion, so that the bearing rubber base assembly  330  is effectively supported in the axial direction, thereby preventing the deflection of an angle between the rotation shaft and the rubber base assembly, and reducing the degree of wear of the rotation shaft. 
     The bracket insertion portion  3310  mating with the bottom shell  310  is arranged on the rubber base bracket  331 .

The fan nest is formed integrally with the impeller. The motor shaft sleeve is formed integrally with the output shaft  142  of the fan motor. 
     As a transformable embodiment, in the embodiment, the quick release connecting structure  700  includes a fan nest  710  fixedly mounted on the impeller shaft  321  and a motor shaft sleeve  720  fixedly mounted on the output shaft  142  of the fan motor  141 . There are several fan meshing portions  711 , which are uniformly distributed in all directions, formed on the fan nest  710 , correspondingly, there are a corresponding number of motor meshing portions  721 , which are suitable to mate with the fan meshing portions  711 , arranged on the motor nest  720 . The fan meshing portion  711  may enter, through an axial movement, a state of interlocking with the motor nest  721 , so that the impeller shaft  321  and the output shaft  142  of the fan motor  141  are connected each other, and transmission side faces on the motor shaft sleeve and the fan nest extend at a completely axially overlapping part when they are nested.

In the embodiment, the number of the motor meshing portions  721  and the number of the fan meshing portions  711  are 3. The fan meshing portion  711  is a groove, and the motor meshing portion  721  is a protruding claw. As shown in  FIG.  76    and  FIG.  77   . The meshing surface of the motor meshing portion  721  on the motor shaft sleeve  720  is a helical curved surface, the meshing surface corresponding to the fan meshing portion  711  is also a correspondingly mating helical curved surface, and the helical direction of the two mating helical curved surfaces enables the fan motor  141  to drive, when poking the impeller  320  to work, the impeller  320  to axially move towards the direction of the fan motor  141 . Along a transmission direction in which the fan motor drives the impeller to rotate, the fan nest has a guiding-in surface contrary to the transmission side face, which is suitable to guide the fan in the fan nest in a nesting manner. The fan shaft sleeve is fixed connected with the output shaft  142  of the fan motor through the screws or buckles. 
     A clutch actuating mechanism is configured to drive the impeller shaft  321  to axially move relative to the output shaft of the fan motor  141 . The clutch actuating mechanism includes the poking pieces, which are respectively mounted on the bottom shell  310  movably to apply an acting force on the impeller  320 , at two sides of the impeller  320 . As shown in  FIG.  82    to  FIG.  88   , the poking piece  341  consists of four folding surfaces which are connected being vertical to each other and of which spacing segments are not opposite, and has a poking piece pushing portion  3412  with a poking piece protruding point  3411  arranged on the top, a poking piece driving portion  3413  which is arranged on the upper surface of the lowest folding surface and is suitable for manual poking, and a poking piece limiting portion  3414  which is arranged on the lower surface of the lowest folding surface, as shown in  FIG.  82   . The poking piece driving portion  3413  is fixedly connected with the poking piece pushing portion  3412 . The poking piece protruding point  3411  is arranged at the position close to the rotation shaft of the impeller  320 . The poking piece limiting portion  3414  mates with a bottom shell limiting groove  342  which is formed on the bottom shell  310  and has a bevel. When the impeller  320  moves to the position, where it is separated from the fan motor  141 , along the direction far away from the fan motor  141 , the poking piece limiting portion  3414  is locked from the bottom shell  310 . When the bevel moves in the direction close to the fan motor  141 , the poking piece limiting portion  3414  is unlocked from the bottom shell  310 . The poking piece protruding point  3411  has a function of making the poking piece  341  contact the impeller  320 . The poking piece driving portion  3413  makes it convenient to manually operate the poking piece  341 . The limiting buckle of the poking piece limiting portion  3414  enables the poking piece  341  to be connected in the bottom shell limiting groove  342  which is formed on the bottom shell  310  in a sliding manner. By limiting a stroke length of the bottom shell limiting groove  342 , the stroke of the poking piece  341  is limited. A guide flange  3416 , which is connected in a sliding manner with the bottom shell guide portion  322  formed on the bottom shell  310 , is also formed on the poking piece, so that the poking piece limiting portion  3414  slides along the direction parallel to the axis of the impeller to prevent a beat generating in the sliding process, as shown in  FIG.  82   . 
     The motor poking the impeller to rotate is mounted on the base module, that is, the impeller shaft is connected with the motor shaft, and there is the poking piece  341 , which is configured to disassemble the impeller from the motor, at the side, close to the motor, of the impeller shaft. 
     As shown in  FIG.  75   , the poking piece  341  is movably mounted on the part adjacent to the impeller  320 , and includes: the poking piece pushing portion  3412  and the poking piece driving portion  3413 . The poking piece pushing portion  3412  is suitable to contact the impeller  320 , and is configured to drive the impeller  320  to axially move. The poking piece driving portion  3413  is fixedly connected with the poking piece pushing portion  3412 , and is at the position where it can be contacted through a gap from the outside. The poking piece driving portion  3413  of the poking piece  341  in the embodiment can be contacted from the gap, then the operators drives, through the poking piece driving portion  3413  at the gap, the poking piece pushing portion  3412  to push the impeller  320  to axially move, thereby it is convenient to disassemble the impeller  320  from the motor. The poking piece  341  in the embodiment also has the poking piece limiting portion  3414  which is formed on the poking piece driving portion  3413 . The poking piece limiting portion  3414  is fixedly connected with the poking piece pushing portion  3412 . The poking piece is locked with the mounted part at the position where the impeller  320  is separated from the motor, that is, after the impeller  320  is separated from the motor, the position of the poking piece is locked, then the impeller  320  is limited at the position where it is separated from the motor, and will not be combined with the shaft sleeve of the motor again. 
     The poking piece is movably mounted on the bottom shell  310  of the air conditioner. The poking piece moves relative to the bottom shell  310  of the air conditioner to push the impeller  320 . The mounting position of the poking piece of the bottom shell  310  is as shown in  FIG.  80    and  FIG.  83   . The poking piece limiting portion  3414  mates with the bottom shell limiting groove  342  which is formed on the bottom shell  310  and has a bevel. The poking piece limiting portion  3414  mates with the bevel. When the impeller  320  moves to the position where it is separated from the motor along the direction far away from the motor, the poking piece limiting portion  3414  is locked with the bottom shell  310 , so that the impeller  320  is limited at the position where it is separated from the motor after moving to the position, and will not be combined with the shaft sleeve of the motor. When the impeller moves along the direction close to the motor, the poking piece limiting portion  3414  is unlocked from the bottom shell  310 , that is, when the impeller  320  and the motor are mounted and connected, the poking piece may move freely, and the impeller  320  is not limited to move towards the motor. 
     As shown in  FIG.  75   , when the number of the poking pieces configured to disassemble the impeller  320  from the motor is 2, the two poking pieces are respectively arranged on two axial ends of the impeller  320 , and poke the impeller  320  in opposite directions. That is, there are the poking pieces arranged on both two end faces of the impeller  320 . The poking piece on the left end face may poke the impeller  320  rightwards to drive the impeller  320  to move rightwards, and the poke piece on the right end face may poke the impeller  320  leftwards to drive the impeller  320  to move leftwards. The poking piece which pokes the impeller  320  in the direction far away from the motor has the poking piece limiting portion  3414 , for example, if the right end face of the impeller  320  is arranged with the motor, that is, the poking piece on the left end face may drive the impeller  320  to go away and separate from the motor, then the poking piece on the right end face has the poking piece limiting portion  3414 , so that the impeller  320  is limited at the position where it is separated from the motor after moving to the position. 
     As a deformation, when the number of the poking pieces configured to disassemble the impeller  320  from the motor is 1, the poking piece is arranged on the end of the impeller  320 , and the reset spring is arranged on the other end of the impeller  320 . The reset spring applies the bias force, towards the motor, on the impeller  320 . The reset spring and the poking piece may be arranged on the same end of the impeller  320 , or they are respectively arranged on two different ends of the impeller  320 . The reset spring may avoid the problem that the impeller  320  cannot mate with the motor shaft effectively due to human causes during carrying and assembling the whole body, and then the motor cannot work normally in a no-load case after being powered on. When the reset spring and the poking piece are respectively arranged on two ends of the impeller  320 , one end of the reset spring presses against the impeller  320  support of the bottom shell  310 , and the other end presses against the impeller  321  shaft. The reset spring pressing against the impeller  321  shaft is on the axis where the acting forces of the end face of the impeller  320  are concentrated, so an axial offset of the impeller  320  relative to the motor is reduced. 
     As shown in  FIG.  82   , the poking piece protruding point  3411  is formed on a contact surface of the poking piece pushing portion  3412  and the impeller  320 . The impeller  320  and the motor are connected in a mating manner by means of a threaded sleeve, so when the impeller  320  is dissembled from the motor, an action of rotating around the motor shaft also forms in the process that the impeller  320  is separated from the motor, and sliding wear generates between the poking piece and the impeller  320 . Therefore, the poking piece protruding point  3411  configured to contact the end face of the impeller  320  is arranged on the poking piece pushing portion  3412  to reduce the contact area between the end face of the impeller  320  and the poking piece, that is, frictional resistance is reduced, so as to reduce damages to the impeller  320  and abnormal noises to the greatest extent. The poking piece protruding point  3411  is close to the position of the rotation shaft of the impeller  320 , so as to make a force bearing point on the end face of the impeller  320  as close as possible to the position of the rotation, and reduce the axial offset when the impeller  320  is separated from the motor. The poking piece limiting portion  3414  includes: a guide flange  3416 , which is connected in a sliding manner with the bottom shell guide portion  322  formed on the bottom shell  310 , is also formed on the poking piece, so that the poking piece limiting portion  3414  slides along the direction parallel to the axis of the impeller  320  to prevent a beat generating in the sliding process. The poking piece limiting portion  3414  further includes: a poking piece hook  3417  which is hooked with the bottom shell limiting groove  342  in the bottom shell  310 . The poking piece limiting portion  3414  slides in the bottom shell limiting groove  342 , so that the poking piece limiting portion  3414  slides along the direction parallel to the axis of the impeller  320  to prevent a beat generating in the sliding process. There is also a poking position  3415  which is formed on the poking piece  341  of the embodiment and is configured to apply an external force to poke the poking piece conveniently. The poking piece consists of four folding surfaces which are connected being vertical to each other and of which spacing segments are not opposite. The poking piece pushing portion  3412  is the folding surface arranged on the top. The poking piece driving portion  3413  is on the upper surface of the lowest folding surface, so it facilitates operation to make the poking piece to move. 
     As a transformable embodiment, for the poking piece which is configured to disassemble the impeller  320  from the motor, the mounting position of the poking piece on the bottom shell  310  goes down, and the spring is arranged on the surface, far away from the poking piece, of the bottom shell  310 . The guide control to the poking piece is realized through a helical spring  310   b  and a spring column  310   a . A deformation slot  3418  is formed on the poking piece. When the poking piece is squeezed downwards to enter the mounting position of the poking piece on the bottom shell  310 , the deformation slot  3418  enables the guide flange  3416  to squeeze and deform towards the center to be pressed in the bottom shell guide portion  322  on the bottom shell  310 . On the edge of the bottom shell guide portion  322 , the deformation slot is formed on the shell. When the poking piece is squeezed downwards to the mounting position of the poking piece on the bottom shell  310 , the deformation slot  3418  on the shell may enable the bottom shell guide portion  322  to expand outwards, and then the guide flange  3416  is pressed in the bottom shell guide portion  322 ; later, the deformation slot  3418  restores, and the bottom shell guide portion  22  is clamped with the guide flange  3416 . That is, guiding and limiting of the poking piece driving portion  3413  of the poking piece on the mounting position of the poking piece on the bottom shell is realized through the mating between the guide flange  3416  and the bottom shell guide portion  322 . The poking piece limiting portion  3414  which is configured to be hooked with a lower buckle  3108  of the bottom shell  310  is formed on the poking piece. A rib which is configured to limit may also be arranged on the bottom shell  310  to further limit a moving stroke of the poking piece. The bottom shell guide portion  322  of the mounting position of the poking piece on the bottom shell  310  may be strip-shaped as shown in  FIG.  86   . As a deformation slot, as shown in  FIG.  88   , the bottom shell guide portion  322  on the bottom shell  310  may consist of three buckles, which are respectively the first buckle, the second buckle and the third buckle from left to right. When the guide flange  3416  is locked with the first buckle, the impeller  320  is pushed to the position where it is separated from the motor. When the guide flange  3416  is pushed to be locked with the second buckle from the position where it is locked with the first buckle, the poking piece pushing portion  3412  of the poking piece is between the impeller  320  and the motor without interfering the assembly of the impeller  320  and the motor. When squeezed to be mounted on the bottom shell  310 , the poking piece is connected with the third buckle on the bottom shell  310  in a locking manner. By setting the first buckle, the second buckle and the third buckle, the position of the poking piece pushing portion  3412  may be figured out, that is, whether it interferes the mating between the fan blade and the motor. 
     As a transformable embodiment, when the number of the poking pieces is 1, the poking piece is arranged on the end of the impeller  320 , and the reset spring is arranged on the other end of the impeller  320 . The reset spring applies the bias force, towards the motor, on the impeller  320 . When the reset spring and the poking piece are respectively arranged on two ends of the impeller  320 , one end of the reset spring presses against the impeller  320  support of the bottom shell  310 , and the other end presses against the impeller  321  shaft. When the impeller  320  is mounted to mate with the motor, the reset spring directly acts to push the impeller  320  to the direction of the motor. 
     The air and water duct module is connected with the base part  101  module through a second mounting structure. In a working state, the second mounting structure includes second fixing holes arranged on the bottom shell  310  in columns on left and right, a second screw holes formed on the base part  101  and corresponding to the second fixing holes at a mounting position of the bottom shell  310  and second screws configured to penetrate through the second fixing holes to form screwed connection with the second screw holes. When the bottom shell  310  is connected on the base part  101 , the bottom shell  310  is fixed on the base part  101  by means of an assembling and disassembling structure at first, and then the bottom shell  310  is fastened on the base part  101  by means of the second screw. When the bottom shell  310  is disassembled from the bottom shell  310 , first the second screw is disassembled to release the fastened connection between the bottom shell  310  and the base part  101 , and then they are separated through the assembling and disassembling structure, as shown  FIG.  92    to  FIG.  94   . 
     The assembling and disassembling structure includes: the base part  101  and the bottom shell  310  detachably mounted on the base part  101 . A locking structure is also arranged between the bottom shell  310  and the base part  101  to be configured to lock or unlock the bottom shell  310  when the bottom shell  310  is assembled or disassembled. After releasing the fasten connection between the bottom shell  310  and the base part  101 , the operator may poke the poking plate  343  while holding the bottom shell  310 , and then take down the bottom shell  310  from the base part  101 , so as to prevent the problem that the bottom shell  310  may be separated from the base part  101  to fall after the fasten connection between the bottom shell  310  and the base part  101  in the air conditioner is released, thereby protecting the operator and preventing the parts on the bottom shell  310  from falling to be damaged. The locking structure includes: a poking plate  343  arranged on the bottom shell  310  in a sliding manner, and a locking groove arranged on the base part  101 . The poking plate  343  is suitable to partially extend into the locking groove to lock the bottom shell  310  with the base part  101 . When the poking plate  343  does not extend into the locking groove, the bottom shell  310  is unlocked from the base part  101 . 
     As a deformation, the locking structure includes: a poking plate  343  arranged on the bottom shell  101  in a sliding manner, and a locking groove arranged on the base part  310 . The poking plate  343  is suitable to partially extend into the locking groove to lock the bottom shell  310  with the base part  101 . When the poking plate  343  does not extend into the locking groove, the bottom shell  310  is unlocked from the base part  101 . The bottom shell  310  and the base part  101  have the assembling and disassembling structure. As shown in  FIG.  92   , the poking plate  343  includes: the poking plate driving portion  3432  mating with the bottom shell  310  in a sliding manner and a poking plate pushing portion  3431  fixed on the poking plate driving portion  3432 . The poking plate driving portion  3432  is suitable to drive the poking plate pushing portion  3431  to extend into the locking groove. By applying an external force on the poking plate driving portion  3432 , the poking plate pushing portion  3431  is driven to extend into or extend out of the locking groove. When extending into the locking groove, the poking plate pushing portion  3431  is locked with the locking groove. When extending out from the locking groove, the poking plate pushing portion  3431  is separated from the locking groove to be unlock. A locking bevel mating with the locking groove is formed on the poking plate pushing portion  3431 . Through the wedge-shaped bevel, when the poking plate pushing portion  3431  extends into the locking groove, they are locked together. 
     As shown in  FIG.  93   , a guide groove  310   c  and a guide bar  310   d  are formed on the bottom shell  310 . A sliding bar  3433 , which mates with the guide groove  310   c  on the bottom shell  310  in a sliding and limiting manner, is formed on the poking plate driving portion  3432 , so as to guide and limit the poking plate driving portion  3432 . A sliding chute  3434 , which mates with the guide bar  310   d  on the bottom shell  310  in a sliding and limiting manner, is formed on the poking plate driving portion  3432 , so as to guide and limit the poking plate driving portion  3432 . It is feasible to select one of the sliding bar  3433  and the sliding chute  3434  to be arranged on the poking plate driving portion  3432 . In order to improve the assembly accuracy, both the sliding bar  3433  and the sliding chute  3434  may be arranged. 
     Two ends of the sliding bar  3433  and the sliding chute  3434  along the sliding direction are correspondingly arranged with bevels mating with the guide groove  310   c  or the guide bar  310   d , so that the poking plate  343  mates with the bottom shell  310  in a clamping manner when it is on a locked position or an unlocked position. That is, when the poking plate pushing portion  3431  of the poking plate  343  extends into the locking groove, the poking plate  343  mates with the bottom shell  310  in a clamping manner, and the poking plate  343  achieves the aim of locking the bottom shell  310  and the base part  101 . When the poking plate pushing portion  3431  of the poking plate  343  extends out from the locking groove, the poking plate  343  still mates with the bottom shell  310  in a clamping manner, and will not fall off from the bottom shell  310 . A pushing position  3435  suitable to push the poking plate  343  is formed on the poking plate driving portion  3432 , which is convenient for the operator to drive the poking plate driving portion  3432 . 
     There are two locking structures, and they are symmetrically arranged at the joint of the lower part of the bottom shell  310  and the edge of the base part  101 . The two locking structures may effectively lock the bottom shell  310  with the base part  101 , and it is convenient for the operator to push by two hands the poking plates  343  of the two locking structures at the same time when disassembling the bottom shell  310  and the base part  101 . As shown in  FIG.  94   , the moving direction of the poking plate  343  is vertical to the long side direction of the base part  101 . Locking and unlocking between the bottom shell  310  and the base part  101  is realized by vertically pushing the poking plate  343  up and down. Of course, the moving direction of the poking plate  343  may also be parallel to the long side direction of the base part  101 . Locking and unlocking between the bottom shell  310  and the base part  101  is realized by horizontally pushing the poking plate  343  leftwards and rightwards. 
     As shown in  FIG.  111   , a bottom shell structure includes: the bottom shell  310  with an air outlet passage  2  and a volute tongue  3 . The impeller  320  is detachably mounted on the bottom shell  310 . An air outlet structure is arranged on the air outlet passage  2 . The volute tongue  3  is arranged in the air outlet passage  2 , and is configured to eliminate a vortex generating in the air outlet passage. The volute tongue  3  is formed integrally on the bottom shell  310 , and the projects, along the vertical direction of the mounting state, of the air outlet structure and the volute tongue  3  do not overlap. 
     Through the bottom shell structure of the air conditioner provided by the disclosure, because the volute tongue  3  is formed integrally on the bottom shell  310 , vibration generating between the volute tongue  3  and the bottom shell  310  in a working condition is avoided. 
     Meanwhile, as shown in  FIG.  81    to  FIG.  111   , the projects, along the vertical direction of the mounting state, of the air outlet structure and the volute tongue  3  do not overlap, so when the bottom shell  310  is ejected from a mold, the air outlet structure and the volute tongue  3  do not influence each other, which is beneficial to forming integrally the volute tongue  3  and the bottom shell  310 . 
     In the embodiment, the sliding structure mating with the base part  101  in a sliding manner is arranged on the bottom shell  310 . The bottom shell  310  is detachably mounted on the base part  101  through the sliding structure. 
     Specifically, the air duct and the water duct are formed on the bottom shell  310 . When the air duct, the water duct and the impeller  320  need to be cleaned, the bottom shell  310  is directly disassembled from the base assembly. Compared with the problem in the conventional art that the air duct and the water duct cannot be cleaned due to arranging the air duct and the water duct on the bottom shell  310  of the base part  101 , or the performance of the fan motor  141  is influenced by wetting when the air duct, the water duct or the impeller  320  are cleaned caused by fixedly connecting the fan motor  141  with the impeller  320  or fixedly mounting the fan motor  141  on the bottom shell  310  formed with the air duct and the water duct, the embodiment can not only clean the air duct, the water duct and the impeller  320 , but also prevent the fan motor from being damaged by wetting. 
     In the embodiment, a top limiting structure  6  mating with the limiting portion on the base part  101  is formed on the top of the bottom shell  310 . So the position of the bottom shell  310  on the base part  101  is limited. 
     In the embodiment, the impeller  320  with the impeller shaft is mounted on the bottom shell  310 . The impeller shaft is arranged at a bobbin of the impeller  320  in a penetration manner. One end of the impeller shaft is rotationally mounted in the bottom shell  310 , and the other end is in transmission connection with the fan motor  141 . As shown in  FIG.  110   , the end, far away from the motor assembly, of the impeller shaft is also arranged with the reset spring  722 . The reset spring  722  applies the bias force, towards the fan motor  141 , on the impeller  320 . The reset spring  722  applies a constant bias force on the impeller  320  to make the impeller  320  closely lean on the fan motor  141  which is on one side of the impeller  320 , thereby preventing a gap generating between the impeller  320  and the fan motor  141  during dissembling. Meanwhile, after the impeller  320  is disassembled or assembled, the impeller  320  may be squeezed to a working position through the reset spring  722 , thereby preventing whistling sound of the air conditioner caused by the asymmetry between the position of the impeller  320  and the air outlet of the air conditioner. 
     As shown in  FIG.  103   , a bias piece is arranged on the end of the impeller shaft  321 . The bias piece is the reset spring  722 , and includes: a first connecting piece  30  and a spring  32 . One end of the first connecting piece  30  is mounted on the end of the impeller shaft, and the other end is connected with the spring  32 . The end, far away from the first connecting piece  30 , of the spring  32  is connected on the bearing rubber base assembly. The spring  32  is configured to generate the bias force. In the embodiment, as shown in  FIG.  81   , the bias piece further includes: a second connecting piece  31  arranged between the spring  32  and the bearing rubber base assembly  330 . The second connecting piece  31  is connected integrally or detachably on the bearing rubber base assembly  330 . 
     Meanwhile, an inner diameter of the second connecting piece  31  is greater than an outer diameter of the first connecting piece  30 . The first connecting piece  30  is inserted in the second connecting piece  31 . The spring  32  is mounted in a chamber formed between the first connecting piece  30  and the second connecting piece  31 . In an actual working condition, the second connecting piece  31  is in a stationary state, and the first connecting piece  30  is in an active state. The spring  32  provides the bias force for separating the first connecting piece  30  from the second connecting piece  31 , so that the first connecting piece  30  pushes the impeller  320  to press the fan motor  141  tight. 
     Specifically, the first connecting piece  30  has a hollow connecting chamber of which the inner diameter is greater than the outer diameter of the impeller shaft  321 . Specifically, the impeller shaft is in sliding connection with the connecting chamber. During use, it is needed to mount the connecting chamber on the impeller shaft at first, and they can be in lubricating connection through the lubricating oil. 
     As a deformation, the first connecting piece  30  and the impeller shaft  321  may be connected in an interference fit manner. The first connecting piece  30  is closely connected on the impeller shaft  321 , so that they are stably connected. 
     In the embodiment, the first connecting piece  30  is plastic, and the second connecting piece  31  is rubber. 
     In the embodiment, as shown in  FIG.  76   , a motor shaft sleeve  720  is mounted on the motor shaft of the fan motor. The end, close to the fan motor  141 , of the impeller shaft  321  is mounted with a fan nest  710  in transmission mating with the motor. The motor shaft sleeve  720  has a transmission side face mating with the fan nest  710  when rotating along the transmission direction in which the motor drives the impeller  320  to rotate. The transmission side face is configured to apply an axial force, towards the direction of the motor, on the fan nest. So, a function of connecting stably the fan motor  141  with the impeller  320  is realized. 
     Specifically, the motor nest  720  uses a structure of a helical sleeve. The helical sleeve goes deep into the chamber of the fan nest  710 , and then, by means of the axial force, they are connected through the quick release connecting structure. 
     Meanwhile, as shown in  FIG.  81    and  FIG.  9   , the poking piece  341  is arranged on the impeller  320 . The poking piece  341  is suitable to be configured to drive the impeller shaft  321  to move. When the impeller  320  needs to be separated from the fan motor, it is only needed to poke the poking piece  341 , and then the poking piece drives the impeller  320  to move to be separated from the fan motor  141 , thus the process of disassembling the impeller  320  is completed. 
     In the embodiment, as shown in  FIG.  81    and  FIG.  43   , an upper limiting assembly  3001  is a buckle opening downward. An upper clamping structure  302  is fixed on the bottom shell  310  and is suitable to be embedded in the upper limiting assembly  3001 . Specifically, the upper limiting assembly  3001  is a U-shaped groove. The upper clamping structure  302  is inserted in the U-shaped groove with good sealing performance. The upper clamping structure on the top of the bottom shell is inserted with good stability in the U-shaped groove with good sealing performance, meanwhile, flowing of airflow from the U-shaped groove is prevented, thereby ensuring the tightness of the air conditioner. 
     As a deformation, as shown in  FIG.  81   , the upper limiting assembly  3001  is a clamping chamber of which length is consistent with the length of the upper clamping structure  302 . The upper clamping structure  302  is inserted in the clamping chamber with good sealing performance. Adopting a long-distance connection may ensure the stability of the connection while ensuring the sealing performance between the whole bottom shell  310  and the air conditioner. 
     Meanwhile, as shown in  FIG.  81   , the lower limiting assembly  304  is a lug boss protruding towards a side of the bottom shell  310 . The lower part of the bottom shell  310  is fixed with a lower clamping structure  303  mating with the lug boss. The lower clamping structure  303  is a part of the lower edge, close to the base part  101 , of the bottom shell  310 . After the upper clamping structure  302  is clamped with the upper limiting assembly  3001  in a mating manner, the lower clamping structure  303  is suitable to be located on the lug boss, thereby preventing the air and water duct module  300  from sliding out from the bottom of the base part  101 . 
     Specifically, a fixedly connecting structure is a combined structure of the lower limiting assembly  304  and the lower clamping structure  303 . Meanwhile, in a working state, side limiting assemblies  306  are formed on the positions, corresponding to the left and right sides of the bottom shell  310 , of the base part  101 . In  FIG.  81   , the left and right sides of the bottom shell  310  are formed with side clamping structures  307 . The side clamping structures  307  may be connected on the side limiting assemblies  306 , and are configured to prevent the bottom shell  310  from swaying from side to side in a working state relative to the base part  101 . 
     Specifically, the side clamping structure  307  is an elastic buckle. Two elastic buckles clamp the left and right sides of the bottom shell  310 . After the bottom shell  310  is placed in the base part  101 , the side clamping structure is squeezed by the bottom shell  310  to move towards the left and right sides. Meanwhile, a threaded hole  305  is formed on the base part  101 . A through hole is formed on the position, corresponding to the threaded hole  305 , of the bottom shell  310 . The bottom shell  310  may be fixed on the base part  101  through the screw, so that the air and water duct module  300  is connected with the base part  101  better. 
     As shown in  FIG.  89   , in order to facilitate the disassembly and connection between the base part  101  and the air and water duct module  300 , a sliding structure mating with the air and water duct module  300  is arranged on the base part  101 . The air and water duct module  300  is suitable to be pulled out from or pushed in the base part  101  through the sliding structure. 
     In the embodiment, as shown in  FIG.  95   , the guide structure is a sliding rail device  900 . Specifically, the sliding rail device  900  includes a sliding rail base  910  vertically fixed on the base part  101  in a working state, a sliding frame  911  mounted in a sliding chute of the sliding rail base  910  in a sliding manner and a sliding rail end rod of which one end is fixedly mounted on the sliding frame  911 . The other end of the sliding rail end rod being fixedly connected with the air and water duct module. A clamping hook is formed on the sliding rail end rod. The clamping hook is connected with the clamping groove formed on the air and water duct module in an inserting and mating manner. A locating block having a function of locating the sliding rail end rod  912  is arranged on the front end of the sliding rail base  910 . The locating block has an outward extending expanding structure. 
     When the air and water duct module  300  needs to be separated from the base part  101 , it is only needed to pull the sliding rail device  900  to separate them. When the air and water duct module  300  needs to be mounted on the base part  101 , it is only needed to push the sliding rail device  300  in the opposite direction to the base part  101 . 
     As a deformation, specifically, as shown in  FIG.  102   , the sliding structure is a slide  5  which is formed along at least one end of the length direction and is parallel to the width direction. The slide  5  is in line contact with the base part  101 . The slide  5  is a curved structure including some groups of arcs which bend towards the same side and are connected each other in order. Convenience is brought to mounting the bottom shell  310  on the base part  101  through the slide. 
     Through the slide  5  arranged in curved surface, the base part  101  and the bottom shell  310  are in line or surface contact when connected. Compared with the conventional surface contact, such a basic manner can significantly reduce frictional noises between friction surfaces caused by thermal expansion and contraction in industrial control conditions. 
     Meanwhile, as a deformation, the slide  5  may adopt other shapes, for example, a truss structure, as long as that the base part  101  and the bottom shell  310  are in the line or surface contact when connected is satisfied. 
     Drain holes from the water groove to the lower side of the bottom shell  310  are formed on two ends of the bottom shell  310 , and a water collection groove is arranged on the base part  101 . A movable transition water groove is arranged on the water collection groove. A water outlet pipe is arranged on the transition water groove. A water outlet of the water outlet pipe is always in the water collection groove when the transition water groove moves. The transition water groove moves between a ready position and a using position. At the ready position, the whole transition water groove is out of a mounting moving path of the air and water duct module  300 , and at the using position, the transition water groove moves to the position where the drain hole is suitable to drain the condensed water in the water groove in the transition water groove. Then, the condensed water is drained in the water collection groove on the base part  101  via the water outlet pipe of the transition water groove, and drained out via the drain pipe connecting to the water collection groove. 
     As shown in  FIG.  104    and  FIG.  106   , a specific implementation mode of a water collecting structure of the air conditioner includes a water collecting structure of base  103  and a water passage on bottom shell  312 . The water collecting structure of base  103  is arranged on the base part  101  of the air conditioner. A drain pipe  105  is connected on the water collecting structure of base  103 . The water passage on bottom shell  312  is arranged on the air duct assembly  301  of the air conditioner, and is configured to collect the condensed water generated by the air duct assembly  301 . The water passage on bottom shell  312  is connected with the drain pipe  105  through the water collecting structure of base  103 . The water passage on bottom shell  312  mates detachably with the water collecting structure of base  103 . 
     Because the water collecting structure includes the water collecting structure of base  103  on the base part  101  and the water passage on bottom shell  312  arranged on the air duct assembly  301  of the air conditioner, and a drain pipe  105  is connected on the water collecting structure of base  103 , when the air duct assembly  301  is mounted on the base part  101 , the water passage on bottom shell  312  is connected with the water collecting structure of base  103 , and then the air duct assembly  301  is connected with the drain pipe  105 . Meanwhile, because the water collecting structure of base  103  mates detachably with the water passage on bottom shell  312 , when disassembled, the air duct assembly  301  may be disassembled from the base part  101  through the detachable mating between the water collecting structure of base  103  and the water passage on bottom shell  312  without disassembling the drain pipe  105 . In such a manner, when the drain pipe  105  is blocked, the dirt is in the water collecting structure of base  103  or the drain pipe  105 , so workloads and difficulties in the disassembling operation are reduced. 
     In a manner of realizing the connection between the water passage on bottom shell  312  and the drain pipe  105  through the water collecting structure of base  103 , the water collecting structure further includes a sliding water collecting structure  104  which is between the water passage on bottom shell  312  and the water collecting structure of base  103  to connect them. The sliding water collecting structure  104  at least mates detachably with one of the water passage on bottom shell  312  and the water collecting structure of base  103 , and then, when the air duct assembly  301  is disassembled, the water passage on bottom shell  312  and the water collecting structure of base  103  may keep a stable connected state through the sliding water collecting structure  104 , thereby ensuring that the dirt will not fall out in the disassembling process. As shown in  FIG.  104    and  FIG.  105   , in terms of the connection between the sliding water collecting structure  104  and the water collecting structure of base  103 , a first hollow drainage column  1042  is arranged on the bottom of the sliding water collecting structure  104 , a first drainage groove  1032  is arranged on the water collecting structure of base  103 , and the sliding water collecting structure  104  is connected with the water collecting structure of base  103  through the first drainage column  1042  and the first drainage groove  1032 . In terms of the connection between the sliding water collecting structure  104  and the water passage on bottom shell  312 , a third hollow drainage column  3122  is arranged on the water passage on bottom shell  312 , a third drainage groove  1044  is arranged on the sliding water collecting structure  104  corresponding to the third drainage column  3122 , and the water passage on bottom shell  312  is connected with the sliding water collecting structure  104  through the third drainage column  3122  and the third drainage groove  1044 . 
     As a deformed implementation mode, a second hollow drainage column (not shown in the drawing) is arranged on the bottom of the sliding water collecting structure  104 , a second drainage groove (not shown in the drawing) is arranged on the water collecting structure of base  103 , and the sliding water collecting structure  104  is connected with the water collecting structure of base  103  through the second drainage column and the second drainage groove, so that the connection between the sliding water collecting structure  104  and the water collecting structure of base  103  is realized. Meanwhile, when the sliding water collecting structure  104  moves relative to the water collecting structure of base  103 , the second drainage column slides in the second drainage groove adaptively, so as to limit a relative movement between the sliding water collecting structure  104  and the water collecting structure of base  103 , and then the relative movement between the sliding water collecting structure  104  and the water collecting structure of base  103  is realized. To sum up, setting the second drainage column and the second drainage groove realizes not only a function of connecting, but also a function of limiting the relative movement, so that the sliding structure and the connecting structure are integrated effectively, and the sliding water collecting structure  104  and the water collecting structure of base  103  are simplified. Meanwhile, in order to ensure that the sliding water collecting structure  104  and the water collecting structure of base  103  keep the connected state in the disassembling process, the sliding water collecting structure  104  is movably arranged on the water collecting structure of base  103 . When moving towards a disassembling direction, the water passage on bottom shell  312  pushes the sliding water collecting structure  104  to move relative to the water collecting structure of base  103 . Specifically, a first sliding rail  1031  is arranged on the sliding water collecting structure  103 , a first slide block  1041  is arranged on the sliding water collecting structure  1041  corresponding to the first sliding rail  1031 , and the first slide block  1041  slides movably in the first sliding rail  1031 . When the first slide block  1041  slides in the first sliding rail  1031 , the first drainage column  1042  slides in the first drainage groove  1032 , thereby ensuring the stability of connection between the sliding water collecting structure  104  and the water collecting structure of base  103  when the sliding water collecting structure  104  slides in the water collecting structure of base  103 . 
     In addition, the relative sliding between the sliding water collecting structure  104  and the water collecting structure of base  103  is also implemented in a manner that the sliding water collecting structure  104  moves relative to the base part  101 , that is, a second sliding rail (not shown in the drawing) is arranged on the base part  101 , a second slide block (not shown in the drawing) is arranged on the sliding water collecting structure  104  corresponding to the second sliding rail, and the second slide block slides movably in the second sliding rail. When a manner of setting the first sliding rail  1031  on the water collecting structure of base  103 , setting the first slide block  1041  on the sliding water collecting structure  104  corresponding to the first sliding rail  1031 , and meanwhile, setting the second sliding rail on the base part  101 , and setting the second slide block on the sliding water collecting structure  104  corresponding to the second sliding rail is adopted, the relative movement between the sliding water collecting structure  104  and the water collecting structure of base  103  is more stable through the mating between the first sliding rail  1031  and the first slide block  1041  and the mating between the second sliding rail and the second slide block. 
     As shown in  FIG.  106    to  FIG.  108   , the assembling and disassembling direction of the air duct assembly  301  is different from the sliding direction of the first slide block  1041  in the first sliding rail  1031 , so in the process of disassembling the water passage on bottom shell and the water collecting structure of base  103 , a guiding structure is arranged between a sliding drain structure and the water passage on bottom shell  312 . The guiding structure converts the acting force of the water passage on bottom shell  312  along the disassembling direction into the acting force of the sliding water collecting structure  104  along the sliding direction. Specifically, the guiding structure includes a poking structure  3121  fixedly arranged on the water passage on bottom shell  312  and a guiding block  1043  fixedly arranged on the sliding water collecting structure  104 . The guiding block  1043  has a guiding bevel. When the water passage on bottom shell  312  is disassembled, the poking structure  3121  pushes the guiding bevel, so that the first slide block  1041  of the sliding water collecting structure  104  fixedly arranged with the guiding block  1043  slides in the first sliding rail  1031 ; and then in the process of disassembling the air duct assembly  301 , the poking structure  3121  pushes the guiding bevel to decompose the force applied on the guiding bevel into the force along the first sliding rail  1031 , so that the first slide block  1041  of the sliding water collecting structure  104  fixedly arranged with the guiding block  1043  slides in the first sliding rail  11 . That is, movements in two directions may be implemented only by applying the acting force in one direction, so the disassembling operation becomes simpler and more efficient. 
     In addition, a self-locking structure (not shown in the drawing) is arranged on the sliding water collecting structure  104 . When the water passage on bottom shell  312  is assembled in place, the sliding water collecting structure  104  is fixed in the water collecting structure of base  103  through the self-locking structure, and limits the water passage on bottom shell  312  to move on the base part  101 , so that the air duct assembly  301  is assembled in place through the self-locking structure on the sliding water collecting structure  104  without adding the locking structure. 
     As an alternative implementation mode, there are two groups of water collecting structures. The water passages on bottom shell  312  of the two groups of water collecting structures are fixedly arranged on the left and right sides of the air duct assembly  301  respectively, and the water collecting structure of base  103  and the sliding water collecting structure  104 , mating with their own water passages on bottom shell  312 , in the two groups of water collecting structures are arranged on the left and right sides of the base part  101  respectively and correspondingly. 
     Embodiment 4 
     The embodiment provides an evaporator, and a connected structure of the evaporate and a bottom shell. The connected structure mainly includes the bottom shell a 310  and the evaporator arranged on the bottom shell a 310 . 
     The evaporator is an important component of a heat exchange module in an air conditioner. The heat exchange module includes a fin a 220  which is entirely supported by angular frames on two ends and cross section of which is inverted-U-shaped. Two ends of the fin a 220  are arranged with sealing parts, so an open chamber  222  is formed in the inverted-U-shaped inside of the fin a 220 . The pipeline in the fin a 220  is connected with an outdoor unit through connection pipelines consisting of a liquid inlet pipe a 2231  and an air collection pipe a 2232 . In the embodiment, there are tee structures a 2233  and a 2234  arranged on both the liquid inlet pipe a 2231  and the air collection pipe a 2232 . Both sides of the fin a 220  are arranged with outdoor unit connection terminals of the connection pipelines through the tee structures a 2233  and a 2234 . 
     In the embodiment, both the liquid inlet pipe a 2231  and the air collection pipe a 2232  are connected on the side, far away from a motor bracket  110 , of the fin a 220 . One branch passing through the tee structures a 2233  and a 2234  forms a U-shaped bend which bypasses the motor bracket  110  from the side, far away from a back plate of a base part a 101 , of the motor bracket after extending beyond the length of the fin a 220  at a position close to the back plate of the base part a 101 , reaches a lower edge of the back plate of the base part a 101  in a working and mounting state, and bends, at the position close to the back plate of the base part a 101 , towards an end of the base part a 101  on this side. Another branch passing through the tee structures a 2233  and a 2234  extends to the lower edge of the back plate of the base part a 101  in the working and mounting state on this side, and bends, at the position close to the back plate of the base part a 101 , towards the end of the base part a 101  on this side. A fixing structure is arranged on the angular frame  210 . In the embodiment, the fixing structure is a connection pipe clamping groove  211  formed on the angular frame  210 . The extending parts of the connection pipelines are clamped in the connection pipe clamping groove  211  to realize a fixing function. The fixing structure fixes the position of the extending parts of the connection pipelines, thereby improving the security of the pipeline during running. 
     The above embodiment may adjust arrangement of the connection pipelines (namely a combination of the liquid inlet pipe a 2231  and the air collection pipe a 2232 ) according to needs. When the outdoor unit connection terminal needs to be arranged on only one side aiming at a particular user, it is only needed to connect the pipeline of the fin a 220  with the liquid inlet pipe a 2231  and the air collection pipe a 2232  at the proper position of the corresponding side of the fin a 220 . 
     When it is needed to arrange the outdoor unit connection terminals on two sides, both the connection pipelines in the above embodiment may also be connected on the side, close to the motor bracket  110 , of the fin a 220 . In such a manner, convenient assembly and disassembly may be realized. However, in this case, if one branch passing through the tee structures a 2233  and a 2234  still extends beyond the length of the fin a 220  from the position close to the back plate of the base part a 101 , and reaches the end, far away from the motor bracket  110 , of the base part a 101 , it is needed to arrange four side-by-side pipelines on the side close to the motor bracket  110 , which increases the length of the heat exchange module, and then increases the whole length of the indoor unit. However, if a solution that one branch passing through the tee structures a 2233  and a 2234  extends beyond the length of the fin a 220  from the position, far away from the base part a 101 , of the fin a 220  is adopted, there is no such problem. But after the exterior module  400  is opened, the inside looks messy. 
     The evaporator of the embodiment mainly consists of the fin a 220  formed with a number of refrigerant flow channels. The refrigerant flow channel are connected in order through U-shaped pipes therebetween. An open end of the U-shaped pipe is detachably arranged with an elbow to form a complete refrigerant flow channel. The refrigerant flow channel includes a refrigerant inlet and a refrigerant outlet arranged on the first side of the fin a 220 , and further includes the liquid inlet pipe a 2231  and the air collection pipe a 2232  respectively connected with the refrigerant inlet and the refrigerant outlet. A number of liquid inlet pipes a 2231  and a number of air collection pipes a 2232  are respectively combined into a header liquid inlet pipe a 2231  and a header air collection pipe a 2232  through a liquid separating head a 4  and an air collecting head a 5 . In the embodiment, the fin a 220  and the liquid inlet pipe a 2231  and the air collection pipe a 2232  arranged thereon are preferentially arranged on the same side of the base part a 101 , so that the fin a 220  may be assembled on the base part a 101  from the top down. The significance of arranging the fin a 220  and the liquid inlet pipe a 2231  and the air collection pipe a 2232  arranged thereon on the same side of the base part a 101  lies in: after the fin a 220  and the liquid inlet pipe a 2231  and the air collection pipe a 2232  are formed into an assembly, and the assembly is assembled with the bottom shell a 310 , there is no need to bend the liquid inlet pipe a 2231  and the air collection pipe a 2232  to another side of the bottom shell a 310 , so that the mounting steps are simplified. Specifically, there is no need to manually bend the liquid inlet pipe a 2231  and the air collection pipe a 2232  and manually bend them back to design angles after assembling is completed, so this manner is suitable to use mechanized automated assembly, helps to improve the production efficiency and reduce the production cost. Specifically, referring to  FIG.  112   ,  FIG.  113    and  FIG.  114   , the evaporator may be directly assembled on the bottom shell a 310  from the top down. 
     It is to be noted that assembling the evaporator on the bottom shell a 310  from the top down is that after the base part a 101  is fixed, the evaporator may be directly mounted on the base part a 101  from the front side of the base part a 101 . For example, when the base part is arranged horizontally in a form as shown in  FIG.  112   , the evaporator is assembled from the top down as shown in the drawing; when the base part is vertically arranged, the evaporator may be mounted horizontally on the base part a 101 . 
     On the other hand, when the existing air conditioner is mounted, the joint where the liquid inlet pipe a 2231  and the air collection pipe a 2232  are connected with the outdoor unit is on the rear side of the base part a 101 , it is needed to keep the base part a 101  in a forward supported state to complete the connection of the pipes in the process of mounting the air conditioner. In the above implementation mode, obviously the liquid inlet pipe a 2231  and the air collection pipe a 2232  are on the front side of the base part a 101  together with the evaporator, so there is no need to support forward the base part a 101  in the process of mounting the air conditioner. 
     In the embodiment, water grooves a 312  are arranged on the front end and the back end, corresponding to the evaporator, of the bottom shell a 310 . The liquid inlet pipe a 2231  and the air collection pipe a 2232  are connected on the evaporator (namely the fin a 220 ). The liquid inlet pipe a 2231  and the air collection pipe a 2232  are bent and arranged in the water groove a 312 . Thus, in the running process of the air conditioner, after the evaporator contacts with air carrying water vapor, the water vapor condenses on the surface of the evaporator, and gather in the water groove a 312  along the surface of the evaporator, and after extending in the water groove a 312 , the liquid inlet pipe a 2231  and the air collection pipe a 2232  may keep cool by means of the water in the water groove, thereby preventing unnecessary heat exchange between the outside and the refrigerant in the liquid inlet pipe a 2231  and the air collection pipe a 2232 , and helping to improving an Energy Efficiency Ratio (EER) of the air conditioner. Furthermore, the water vapor has a relatively low temperature after condensing, so an effect of keeping the liquid inlet pipe a 2231  and the air collection pipe a 2232  cool is further improved; at the same time, there is always condensed water in the water groove a 312 , so the effect of keeping the liquid inlet pipe and the air collection pipe cool is not decreased in a long-term use. 
     In the embodiment, the liquid inlet pipe a 2231  and the air collection pipe a 2232  are connected on the fin a 220 . There are two groups of liquid inlet pipes a 2231  and the air collection pipes a 2232 , and they extend, towards the two sides of the fin a 220 , out from the evaporator shell Through the above implementation mode, the liquid inlet pipe a 2231  and the air collection pipe a 2232  may be connected with an outdoor unit connection pipe on both sides of the evaporator, so it is beneficial to reducing the step of bending the pipe during mounting the air conditioner. Specifically, when mounting the air conditioner, the operator may select the proper side to directly connect the pipes with the outdoor unit connection pipe, so the step of bending the connection pipe to the other side of the air conditioner is eliminated. 
     It is to be noted that the liquid inlet pipe a 2231  and the air collection pipe a 2232  may be arranged in one group or two groups. When the liquid inlet pipe a 2231  and the air collection pipe a 2232  are arranged in one group: 
     as a preference of the above implementation mode, the liquid inlet pipe a 2231  and the air collection pipe a 2232  are connected on the first side of the fin a 220 , and extend out of the evaporator shell from the first side of the fin a 220 ; the liquid inlet pipe a 2231  and the air collection pipe a 2232  may also be connected on the first side of the fin a 220 , and extend out of the evaporator shell from the second side of the fin a 220  after being bent. 
     Specifically, there are following two forms of making pipe out about that the liquid inlet pipe a 2231  and the air collection pipe a 2232  are connected on the first side of the fin a 220 , and extend out of the evaporator shell from the first side of the fin a 220 : 
     1. the liquid inlet pipe a 2231  and the air collection pipe a 2232  are connected on the first side of the fin a 220  and bent upwards along the contour of the fin a 220  to approach the bottom shell a 310 , and then, they are bent downwards along the contour of the bottom shell a 310  and bent towards the first side of the fin a 220 , so as to extend out of the evaporator shell; 
     2. as an alternative of the above implementation mode, the liquid inlet pipe a 2231  and the air collection pipe a 2232  are bent downwards along the contour of the fin a 220  to be far away from the bottom shell a 310 , and bent towards the first side of the fin a 220 . 
     Because the inside of the chamber formed between the base part a 101  and the evaporator shell may be configured to arrange the motor and other parts, by adopting the above two forms of making pipe out, that is, the liquid inlet pipe a 2231  and the air collection pipe a 2232  are arranged along the contours of the base part a 101  and the evaporator shell, the liquid inlet pipe a 2231  and the air collection pipe a 2232  are prevented from occupying available space, and structure design of the air conditioner is optimized. 
     When the liquid inlet pipe a 2231  and the air collection pipe a 2232  are arranged in two groups: 
     As a preferred implementation mode, the first group of liquid inlet pipes a 2231  and air collection pipes a 2232  are connected on the first side of the fin a 220 ; the tee structures a 2233  and a 2234  are respectively arranged on the first group of liquid inlet pipes a 2231  and air collection pipes a 2232 ; the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are respectively connected with two tee structures a 2233  and a 2234 , so that the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are connected with the first group of liquid inlet pipes a 2231  and air collection pipes a 2232 . In such case, the first group of liquid inlet pipes a 2231  and air collection pipes a 2232  extend out of the evaporator shell towards the first side of the fin a 220 , and the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  extend towards the second side of the fin a 220  from the joint, and extend out of the evaporator shell from the second side of the fin a 220 . 
     Specifically, there are several forms of arranging pipes for the second group of liquid inlet pipes a 2231  and air collection pipes a 2232 . The different forms of arranging pipes may achieve different effects, which are illustrated below by giving examples in combination with the drawings  FIG.  115   ,  FIG.  116   ,  FIG.  117   ,  FIG.  118   ,  FIG.  119    and  FIG.  120   . 
     Specifically, the fin a 220  is formed by connecting a number of folding fins in order. The first folding fin is arranged close to the base part a 101 , and the last folding fin is farthest from the base part a 101 . After extending to the second side of the fin a 220 , the liquid inlet pipe a 2231  and air collection pipe a 2232  extend out towards the second side of the fin a 220  after being bent. 
     As a preferred implementation mode, the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  extend from the upper part of the fin a 220  (especially the upper part of the first folding fin) to the second side of the fin a 220 . Preferably, the parts, across the top of a first folding evaporator, of the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are arranged slantwise along the top surface of the evaporator, and an included angle between an inclined direction and a horizontal direction is 0-10 degrees. Specifically, as shown in  FIG.  118   , the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  may extend on the top surface of the evaporator at angles of inclination 0 degree, namely horizontally, 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, and 10 degrees. The angle of inclination is the included angle between the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  and the bottom shell a 310 . 
     As a preferred implementation mode, the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are bent upwards along the contour of the fin a 220  to approach the bottom shell a 310  on the second side of the fin a 220  at first, and then, they are bent downwards along the contour of the bottom shell a 310  and bent towards the first side of the fin a 220 , so as to extend out from the evaporator shell. 
     As an alternative of the above implementation mode, the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are bent downwards along the contour of the fin a 220  to be far away from the bottom shell a 310  on the second side of the fin a 220  at first, and then, they are bent towards the first side of the fin a 220 . The beneficial effects of the above two forms of arranging the pipes in a bending manner have been elaborated in the above implementation mode, so they will not be repeated here. 
     As an alternative of the above implementation mode, referring to  FIG.  121   , the front end or the rear end of the bottom shell a 310  is arranged with the water groove a 312 . The second group of liquid inlet pipes a 2231  and air collection pipes a 2232  may extend from the first side of the fin a 220  to the second side of the fin a 220  through any water groove. The beneficial effect of setting the liquid inlet pipe a 2231  and the air collection pipe a 2232  in the water groove a 312  has been elaborated in the above implementation mode, so it will not be repeated here. 
     As an alternative of the above implementation mode, referring to  FIG.  122   , the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  may extend to the second side of the fin a 220  through the lower end of the first folding fin. Or, the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  may extend to the second side of the fin a 220  through the lower end of any folding fin. 
     It is to be noted that, in the above implementation mode, the upper part of the fin a 220  is the position above the upper surface, and preferably, the pipe is arranged from the position above the top surface of the first folding fin as shown in  FIG.  118    and close to the fin a 220 . The lower end of the first folding fin is the position below the lower surface of the first folding fin, and preferably, the pipe is arranged from the position below the lower surface of the first folding fin and close to the fin a 220 . In such a manner, the liquid inlet pipe a 2231  and the air collection pipe a 2232  are arranged in the evaporator without occupying the mounting space of other parts. Specifically, the lower end of the fin a 220  is the position below the inner surface of the fin a 220 . The position may be set close to the surface of the fin a 220  or away from the surface for a certain distance, and may be located by means of the fin a 220  or the angular frame and other structure, which will not be limited or elaborated here. Those skilled in the art may design and implement, according to the above description, the form of arranging the liquid inlet pipe a 2231  and the air collection pipe a 2232  relative to the fin a 220 . 
     The first group of liquid inlet pipes a 2231  and air collection pipes a 2232  and the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are not limited to be connected on the same side of the fin a 220 , and they may be respectively connected on two sides of the fin a 220 . When the first group of liquid inlet pipes a 2231  and air collection pipes a 2232  and the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are respectively connected on the two sides of the fin a 220 , the first group of liquid inlet pipes a 2231  and air collection pipes a 2232  extend out of the evaporator shell on the first side, and the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  extend out of the evaporator shell on the second side. 
     Preferably, the parts, outside the water groove a 312 , of the liquid inlet pipe a 2231  and the air collection pipe a 2232  are arranged with an insulated structure. The insulated structure is an insulated cotton layer covered on the outer diameters of the liquid inlet pipe a 2231  and the air collection pipe a 2232 . 
     As a preferable implementation mode, the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are connected with the first group of liquid inlet pipes a 2231  and air collection pipes a 2232 . The tee structures a 2233  are respectively arranged on the first group of liquid inlet pipes a 2231  and air collection pipes a 2232 , and the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are respectively connected with two tee structures a 2234 , so that the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  are connected with the first group of liquid inlet pipes a 2231  and air collection pipes a 2232 . Because the liquid separating head a 4  and the air collecting head a 5  which occupy more space, and a certain pipe bending structure are arranged between the liquid inlet pipe a 2231  and the air collection pipe a 2232  and the heat exchanger k 104 , connecting the first group of liquid inlet pipes a 2231  and air collection pipes a 2232  with the second group of liquid inlet pipes a 2231  and air collection pipes a 2232 , and bending the second group of liquid inlet pipes a 2231  and air collection pipes a 2232  to the second side of the fin a 220  may save the inner space of the fin a 220  effectively, and reduce the assembling step. In addition, the refrigerant flow channel in the fin a 220  consists of the U-shaped pipe and the bend, and the bend may be detachably connected on the U-shaped pipe, so taking the side with the bend of the fin a 220  as the first side facilitates assembly. That is, according to the needs of spatial arrangement of the air conditioner, the air collecting head a 5  connected integrally with a number of air collecting branch pipes k 103  and the liquid separating head a 4  connected integrally with a number of liquid inlet branch pipes k 102  are arranged on the right side or the left side of the evaporator, and then the liquid separating head a 4  and the air collecting head a 5  are connected with the liquid inlet pipe a 2231  and the air collection pipe a 2232 . A number of liquid inlet branch pipes k 102  and a number of air collecting branch pipes k 103  are respectively connected integrally through the liquid separating head a 4  and the air collecting head a 5 , so the inner space of the air conditioner is saved. 
     As a preferred implementation mode, the left side of the heat exchanger k 104  arranged on the bottom shell  310  is arranged with a number of liquid inlet branch pipes k 102  and air collecting branch pipes k 103 , the liquid separating head a 4  of which one end is connected integrally with a number of the inlet branch pipes k 102 , the air collecting head a 5  of which one end is connected integrally with a number of the air collecting branch pipes k 103 , and the liquid inlet pipe a 2231  connected with the other end of the liquid separating head a 4  and the air collection pipe a 2232  connected with the other end of the air collecting head a 5 . 
     As a preference of the above implementation mode, the liquid inlet pipe a 2231  and the air collection pipe a 2232  on the left side of the heat exchanger k 104  are arranged in parallel. Meanwhile, the liquid inlet pipe a 2231  and the air collection pipe a 2232  extending to the right side of the heat exchanger k 104  are arranged in parallel. A liquid inlet header pipe and an air collection header pipe have an advantage of optimizing the spatial arrangement of the evaporator by being arranged in parallel. 
     The evaporator, the heat exchanger k 104 , the liquid inlet header pipe, the air collection header pipe and a T-branch pipe are arranged on the same side of the bottom shell of the air conditioner. During mounting, there is no need to arrange the pipes on two sides of the bottom shell, so the difficulty of assembling and disassembling the evaporator is reduced, a foundation is laid for mechanized and automated production, and the efficiency of assembling and disassembling the air conditioner is improved. 
     The embodiment also provides an air conditioner. The air conditioner has all technical features of the above evaporator part, so it also has the beneficial effects of the evaporator part. 
     Embodiment 5 
     The embodiment also provides a simplified angular frame structure. As shown in  FIG.  125    to  FIG.  128   , the simplified angular frame structure includes a simplified angular frame body a 210 . The simplified angular frame body a 210  is suitable to be fixed on a side plate k 105  of the heat exchanger kk 104 , and has a simplified angular frame limiting portion k 1012  configured to limit the connection pipe arranged on the heat exchanger k 104 . 
     The simplified angular frame structure of the embodiment not only has a simple structure, but also may make the connection pipe arranged above the heat exchanger k 104  more stable. The connection pipe is less likely to sway when the air conditioner indoor unit is transported, so it will not collide with the part, out of the side plate k 105 , the radiating pipe k 108 . 
     There are two simplified angular frame limiting portions k 1012 . Those skilled in the art may also arrange more simplified angular frame limiting portions or integrate them into one according to needs. 
     The simplified angular frame limiting portions k 1012  are two clamping pieces arranged opposite to each other on the simplified angular frame body a 210 . A clamping space for clamping the connection pipe is formed between the two clamping pieces. The clamping space opening up formed by the two clamping pieces is convenient to be assembled and disassembled, is easy to be produced automatically, and has a good limiting effect. 
     The clamping piece has elasticity. When the connection pipe enters into the clamping space, the clamping piece deforms elastically, and clamps the connection pipe elastically.

The third clamping portion m 452  is preferably a bump. The bump extends in the space between the two side walls of the U-shaped groove via the opening of the U-shaped groove. In addition, an inwards-sunken groove is formed at a position on the surface of the side, facing towards the mounting body m 44 , of the second strip-shaped body m 451 , and the position avoids the position of the third clamping portion m 452 , so as to reduce the weight of the second strip-shaped body m 451 . Another end of the spring is fixed on the part adjacent to it, for example, the base part s 101 , the air duct assembly, or the evaporator. 
     A stepped face is formed between the second pressing portion m 453  and the end face of the other end of the second strip-shaped body m 451 . The stepped face leans against the inner surface of the panel s 412 , so as to locate whether the panel  412  is mounted in place when mounting the panel s 412 .

     As shown in  FIG.  160   , the whole panel s 412  is L-shaped, its vertical part m 23  is arranged relative to the base part s 101 , and its horizontal part m 22  is formed on the top of the vertical part m 23 . The end, far away from the vertical part m 23 , of the horizontal part m 22  leans against the inner surface of the top of the base part s 101 . Two side plates m 7  are also included. The two side plates are arranged on two side wall ends, facing towards the base part s 101 , of the vertical part m 23 , and extend upwards. The chamber is formed between the two side plates m 7  and the panel s 412  and the base part s 101 . The mounting body m 44  is formed on the inner side wall of the side plate m 7 . The side plate m 7  is detachably connected with the base part s 101 , so that the two side plates m 7  are on two ends of the panel s 412 . 
     Preferably, there are air outlet modules arranged on the bottom of the base part s 101  and the bottom of the panel s 412 . The air outlet is formed on the air outlet module. By fixing the air outlet module on the base part s 101 , the air outlet module is on the bottom of the panel s 412  and the base part s 101 , so the air outlet module, the panel s 412 , the two side plates m 7  and the base part s 101  form the whole exterior of the air conditioner wall-type unit. 
     The two air inlets p 23  are formed on the horizontal part m 22  of the panel s 412 . The two third through holes m 11  are formed on the vertical part m 23  of the panel s 412 . The two third through holes m 11  are on two sides of the two air inlets.

Along the width direction of the horizontal part m 22 , two mounting bodies m 44  are respectively formed on the inner surfaces of the two side plates m 7 . A second connecting portion m 454  is on the end face of the end, facing towards the spring, of the second strip-shaped body m 451 . As a deformation, the connecting piece may also be transformed into a connecting shaft, so as to sheath the spring on this end of the second strip-shaped body m 451 . The third clamping portion m 452  of the second strip-shaped body m 451  is inserted in the fourth clamping groove m 441 , and the second pressing portion m 453  extends out of the third through hole m 11 . When the second pressing portion m 453  is pressed towards the chamber, the second strip-shaped body m 451  and the second pressing portion m 453  do a linear retracting movement along the width direction of the horizontal part m 22  of the panel s 412 , and then the third through hole m 11  on the panel s 412  separates from the second pressing portion m 453 , and the panel s 412  is disassembled from the air conditioner for cleaning conveniently. Meanwhile, other parts in the chamber are exposed, so it is convenient to clean and overhaul the other parts; for example, the evaporator is cleaned, and the electrical box and other structures are overhauled. 
     For the air conditioner wall-type unit in the embodiment, when the panel s 412  needs to be disassembled, it is only needed to press the second pressing portion m 453  towards the chamber along the width direction of the horizontal part m 22  of the panel s 412 , that is, the second pressing portion m 453  is pressed on the front of the wall-type unit to make the second pressing portion m 453  extend in the chamber, and the panel s 412  breaks away from the limit of the second pressing portion m 453 , and is dissembled from the base part s 101 ; then, the panel s 412  may be removed, and the acting force on the second pressing portion m 453  is taken off. After the panel s 412  is removed, under the action of the reset force of the spring, the second limiting piece m 45  extends to the third through hole m 11 , so that the second pressing portion m 453  resets and locates at the start position. The panel s 412  and the evaporator exposed are cleaned, and the electrical structures are overhauled; after they are cleaned or overhauled, it is only needed to sheath the panel s 412  and the third through hole m 11  on the second pressing portion m 453 , so that the stepped face between the second strip-shaped body m 451  and the second pressing portion m 453  leans against the inner surface of the panel s 412 , and then, the panel s 412  may be mounted on the base part s 101 . In such a manner, when assembled and disassembled, the panel s 412  does not deform, and the fastness of mounting the panel s 412  on the base part s 101  is ensured. The pressing way is convenient to disassemble and assemble the panel s 412 . 
     The following is an alternative embodiment of the embodiment. 
     As a deformation of the support, the support may also be in other shapes, for example, an L-shaped support plate or a similar sliding chute. The second limiting piece m 45  is in overlap joint with the horizontal part of the L-shaped support plate. The similar sliding chute is configured to support the second limiting piece m 45 , so that the second limiting piece m 45  may extend and retract on it more smoothly. As a further deformation, the support may not be arranged, and the second limiting piece m 45  is supported only through a mating relationship between the third clamping portion m 452  and the fourth clamping groove m 441  on the second limiting piece m 45 . 
     As shown in  FIG.  164    and  FIG.  165   , as the first deformation mode of the position of forming the third through hole m 11 , the two third through holes m 11  are formed on the horizontal part m 22  of the panel s 412 . The two third through holes m 11  are respectively on two sides of the two air inlets p 23 . The two third through holes m 11  are long waist-shaped holes extending along the horizontal direction. As shown in  FIG.  166   , a second poking block m 455  is arranged on the side wall of the side, with its back to the mounting body m 44 , of the second strip-shaped body m 451 , the second strip-shaped body m 451  is in the long waist-shaped hole, and the mounting body m 44  is mounted slantwise on other parts adjacent to it, such as the air duct assembly arranged in the chamber or the mounting base of the electrical structure. On end of the spring is sheathed on one end of the second limiting piece m 45 , and the other end is fixed on the other parts adjacent to it, such as the base part s 101 , the air duct assembly and the evaporator. The pressing portion of the limiting piece is in the chamber and leans against the inner surface of the panel, and only the poking block is in the long waist-shaped hole. 
     In the implementation mode, when the panel s 412  needs to be disassembled, under the action of the spring for example, the second poking block m 44  is on the left side of the long waist-shaped hole at beginning, the panel s 412  may be dissembled from the air conditioner after breaking away from the limit of the second poking block m 455  only by poking rightwards the second poking block m 455  to make the second poking block m 455  drive the second limiting piece m 45  to move slantwise towards the third through hole m 11 , and make the second poking block m 455  extend in the chamber. After the panel is removed, the acting force on the second poking block m 455  is taken off; under the reset force of the spring, the second poking block m 455  and the second limiting piece m 45  does the extending movement contrary to the retracting movement, so that the second limiting piece m 45  and the second poking block m 455  are reset to the start position. When the panel s 412  is mounted, the mounting process may be completed only by sheathing the third through hole m 11  of the panel s 412  on the second poking block m 44 , locating the second poking block m 455  on the left end of the third through hole m 11 , and making the end, far away from the vertical part m 23 , of the horizontal part m 22  of the panel s 412  lean against the inner surface of the top of the base part s 101 . In the implementation mode, when the second poking block m 455  is in the third through hole m 11 , the end, facing towards the third through hole m 11 , of the second limiting piece m 45  may also be in the third through hole. When an acting force is applied on the poking block, both the poking block and the end limited in the third through hole extend in the chamber. As a deformation, in the implementation mode, it is unnecessary to arrange the second poking block m 455 , the end, facing towards the third through hole m 11 , of the second limiting piece m 45  directly extends out of the third through hole m 11 . By directly pressing this end of the second limiting piece m 45  to make it move linearly and slantwise on the mounting body m 44  and extend in the chamber, the panel s 412  may be disassembled from the air conditioner. 
     As a second deformation mode of the position of forming the third through hole m 11 , the two side plates m 7  are fixed on two ends of the vertical part m 23  of the panel s 412 , and the two third through holes m 11  are respectively formed on the two side plates m 7 . Correspondingly, the mounting body m 44  is horizontally mounted on the other parts adjacent to its, such as the air duct assembly, the evaporator, the electrical mechanism, or the base part. Correspondingly, the second limiting piece m 45  is horizontally mounted on the mounting body m 44 . One end of the spring is fixed on the second limiting piece m 45 , and the other end is fixed on the parts adjacent to its, such as the air duct assembly, the evaporator, the electrical mechanism, or the base part. In the implementation mode, when the panel s 412  needs to be disassembled, it is only needed to press inwards the second pressing portion m 453  along the horizontal direction to make the whole second pressing portion m 453  retract back to the chamber, then the panel s 412  is disassembled. 
     As a deformation of the third through hole m 11 , there can also be three, four, five and six third through holes m 11 . Each of the third through holes m 11  mates with one extending and retracting mechanism corresponding to one mounting boy m 44 , so as to detachably arrange the panel s 412  on the base part s 101 . The number of the third through holes m 11  is determined according to the actual use situations and requirements of users. 
     As a deformation, it is unnecessary to arrange the two side plates m 7 , the mounting body m 44  may be fixed on other parts. As a further deformation, the panel s 412  may only have the vertical part m 23 . The air inlet p 23  is formed between the top of the vertical part m 23  and the top of the base part s 101 . The third through hole m 11  is formed on the vertical part m 23 . 
     As a deformation, it is unnecessary to form the stepped face between the end faces of the second pressing portion m 453  and the second strip-shaped body m 451 . This end of the second strip-shaped body m 451  directly extends out of the third through hole m 11 . Or, it is unnecessary to arrange the second pressing portion m 453 . 
     As a further deformation, it is unnecessary to arrange the second connecting portion m 454  on the end, facing towards the spring, of the second strip-shaped body m 451 , and one end of the spring is directly connected to this end of the second strip-shaped body m 451  in a sleeving manner. As a deformation, this end of the spring may also be fixed on the second strip-shaped body m 451  in other manners. As a deformation of the first elastic piece m 436 , except the spring, the first elastic piece m 436  may also be a reed or other elastic objects. 
     As a deformation of the second strip-shaped body m 451 , there can also be three, four and five third clamping portions m 452  on the second strip-shaped body m 451 , correspondingly, three, four and five fourth clamping grooves m 441  are arranged on the mounting body m 44 . The multiple third clamping portions m 452  mate with the fourth clamping grooves m 441  one by one, so as to ensure that the second limiting piece m 45  linearly moves in the fourth clamping grooves m 441  more smoothly.

The air outlet frame m 3 , being independent from the panel s 412  of the air conditioner indoor unit, has the air outlet m 31 . The air guide plate b 1  is movably arranged in the air outlet m 31 . 
     As shown in  FIG.  202    and  FIG.  228   , two side plates m 7  upwards extending in a working state are fixedly connected on two side ends of the air outlet frame m 3 . Two ends of the air outlet frame m 3  are respectively connected on the mounting rack s 411  in a sliding manner through two vertically arranged sliding mechanisms arranged between the air outlet frame m 3  and the mounting rack s 411 . Two fixing assemblies m 4  respectively lock the two ends of the air outlet frame m 3  on the mounting rack s 411  through the two side plates m 7 . 
     As shown in  FIG.  204    and  FIG.  206   , each sliding mechanism also includes a first sliding chute m 51  formed on the wall surface, facing towards one side of the side plate m 7 , of the mounting rack s 411 , and a first sliding block m 52  formed on the inner surface, facing towards one side of the mounting rack s 411 , of the side plate m 7  and suitable to be embedded in the first sliding chute m 51 . The end, close to the air outlet frame m 3 , of the first sliding chute m 51  is a flaring groove m 511  suitable to accommodate the first sliding block m 52  and suitable for the first sliding block m 52  to slide in or slide out. Preferably, the flaring groove m 511  is a trapezoid-shaped groove or a trumpet-shaped groove, or of other shapes. 
     When the air outlet frame m 3  needs to be disassembled from the air conditioner, the fixing assembly m 4  first disables the function of locking the side plate m 7 , then after a downward pulling force is applied on the air outlet frame m 3 , the first sliding block m 52  of the side plate m 7  slides downwards in the first sliding chute m 51 . When the first sliding block m 52  slides to the flaring groove m 511 , the first sliding block m 52  is in the flaring groove m 511  and is drawn from the flaring groove m 511 , so that the side plate m 7  and the air outlet frame m 3  are integrally dissembled from the air conditioner to be cleaned. After the side plate m 7  and the air outlet frame m 3  are cleaned, an upwards pushing force is applied on the air outlet frame m 3 , and the first sliding block m 52  of the side plate m 7  slides in the first sliding chute m 51  again from the flaring groove m 511 , so that the air outlet frame m 3  and the side plate m 7  are integrally arranged in the first sliding chute m 51  in a sliding manner. Under the action of the upward pushing force, the side plate m 7  slides to the top of the air conditioner, so that the side plate m 7  and the air outlet frame m 3  are reset, and then locked by the locking assembly m 4 . In such a manner, the air outlet frame m 3  is arranged on the mounting rack s 411  in a sliding manner by pushing and pulling. 
     As a deformation of the first sliding chute m 51 , the first sliding chute m 51  may also be replaced with the first through hole m 53 ; correspondingly, the flaring groove m 511  is replaced with a flaring hole. The flaring hole is a trapezoid-shaped hole or a trumpet-shaped hole, or of other shapes. The specific shape is not limited specifically. 
     As shown in  FIG.  203    and  FIG.  206   , each fixing assembly m 4  includes a first clamping portion m 41  formed on the inner surface, facing towards one side of the mounting rack s 411 , of the side plate m 7 , and a first limiting portion m 42  arranged on the mounting rack s 411  for overlap joint of the clamping portion. When an acting force towards the direction far away from the first clamping portion m 41  is applied on the first limiting portion m 42 , the first limiting portion m 42  unlocks the first clamping portion m 41 . Preferably, the first limiting portion m 42  is step-shaped. The first clamping portion m 41  is a lug boss which may be jointed on the stepped face of the first limiting portion m 42  in an overlapping manner. 
     As shown in  FIG.  207   , the side plate m 7  is a plate, and the mounting rack s 411  is an L-shaped bracket. The horizontal part of the L-shaped bracket is arranged between the top of the panel s 412  and the base part s 101 , and the vertical part is between the panel s 412  and the base part s 101 , extends towards the air outlet frame m 3 , and is on the inner surface of the side plate m 7 . 
     As shown in  FIG.  207   , the air outlet frame m 3  includes an arc-shaped part and a horizontal part fixed on the bottom of the arc-shaped part. The air outlet frame m 3  is formed on the arc-shaped part. When the air outlet frame m 3  is locked on the mounting rack s 411 , the inner surface of the horizontal part leans against the bottom surface of the base part s 101 . The arc-shaped part of the air outlet frame m 3  is convenient to mate with the bottom surface of the panel s 412 . The design of the horizontal part is convenient for that, after the air outlet frame m 3  is locked in place, the inner surface of the horizontal part leans against the bottom surface of the base part s 101 , so that the exterior of the air conditioner is nice-looking and the structure is compact. 
     As shown in  FIG.  203   , the air sweeping mechanism m 12  is mounted on the air outlet frame m 3  at the position of the air outlet m 31 . The air sweeping mechanism m 12  includes a connecting base mounted on the air outlet and at least one air sweeping blade alternately mounted on the connecting base in a swaying manner, for example, the number of the air sweeping blades is one, two, three, four, and so on, and the specific number is set according to the length of the air outlet and users&#39; requirements. The air sweeping blade sways at needed angles along the length direction of the air outlet. By mounting the air sweeping mechanism m 12  on the air outlet of the air outlet frame m 3 , when the air outlet frame m 3  is disassembled from the air conditioner, the air sweeping mechanism m 12  mounted to the air outlet may be disassembled to be cleaned, so convenience is brought to cleaning the air outlet frame m 3  and the air sweeping mechanism m 12 . Multiple air sweeping blades sway in the air outlet to adjust the air outlet direction at the air outlet. The design of the connecting base is convenient to mount the blade in the air outlet. 
     In the air outlet assembly of the embodiment, the air outlet frame m 3  with the air outlet and the panel s 412  are arranged separately. As a single part, when the air outlet needs to be cleaned, the first limiting portion m 42  is poked, so that the first limiting portion m 42  releases the limit to the lug boss, and the lug boss separates from the stepped face of the first limiting portion m 42  to apply a downwards pulling force on the air outlet frame m 3 , then the air outlet frame m 3  and the two side plates m 7  integrally slide downwards in the first sliding chute m 51  or the first through hole m 453 . When the first sliding block m 52  of the side plate m 7  slides in the flaring groove m 511  or the flaring hole, the first sliding block m 52  of the side plate m 7  is drawn from the flaring groove m 511  or the flaring hole, then the air outlet frame m 3 , the two side plates m 7  and the air sweeping mechanism m 12  are disassembled integrally from the air conditioner to be cleaned. After cleaning, the upwards pushing force is applied on the air outlet frame m 3  to push the first sliding block m 52  of the side plate m 7  in the first sliding chute m 51  or the first through hole m 53  via the flaring groove m 511  or the flaring hole, until the inner surface of the horizontal part of the air outlet frame m 3  leans against on the bottom surface of the base part s 101 ; at this point, the air outlet frame m 3  and the side plate m 7  are reset to an initial state, the lug boss on the side plate m 7  is jointed on the stepped face of the first limiting portion m 42  in an overlapping manner, and then the process of mounting the air outlet frame m 3  and the side plate m 7  is completed. In such a manner, a pushing and pulling manner is formed to mount integrally the air outlet frame m 3  and the side plate m 7  on the mounting rack s 411  or disassemble them from the mounting rack s 411 , so as to conveniently clean the air outlet frame m 3 , the side plate m 7  and the air sweeping mechanism m 12 . 
     As a deformation of the sliding mechanism, each sliding mechanism includes the guide rail arranged on the wall surface, facing towards the side of the side plate m 7 , of the mounting rack s 411 , and a sliding assembly arranged on the guide rail in a sliding manner. The side plate m 7  is detachably fixed on one end of the sliding assembly, and this end of the sliding assembly may extend out of the guide rail. The sliding assembly includes a second sliding block (not shown in the drawing) and the connecting piece m 54  fixed on the second sliding block. As shown in  FIG.  208   , a first insertion portion m 541  is formed on one end of the connecting piece m 54 . A first clamping groove (not shown in the drawing) for clamping the first insertion portion m 541  in is formed on the inner surface, facing towards the mounting rack s 411 , of the side plate m 7 . The connecting piece m 54  is an L-shaped plate. The vertical part of the L-shaped plate is fixed on the second sliding block, and the horizontal part is inserted in the first clamping groove. 
     With the sliding rail mechanism of the implementation mode, when the air outlet frame m 3  needs to be cleaned, the fixing assembly m 4  needs to first disables the function of locking the side plate m 7 , then after the downward pulling force is applied on the air outlet frame m 3 , the second sliding block slides downwards on the guide rail, and the L-shaped plate drives the side plate m 7  to slide downwards on the guide rail. When the side plate m 7  slides downwards to the lower end of the guide rail, the first clamping groove on the side plate m 7  is separated from the horizontal part of the L-shaped plate, then the air outlet frame m 3  and the side plate m 7  may be disassembled integrally from the air conditioner. Later, the horizontal part of the L-shaped plate is inserted in the first sliding chute to fix the side plate m 7  with the connecting piece m 54 . When the pushing force is applied on the air outlet frame m 3 , the air outlet frame m 3  and the side plate m 7  slide upwards on the guide rail, so that the air outlet frame m 3  and the side plate m 7  are reset, and then locked by the fixing assembly m 4 . The sliding mechanism of the implementation mode realizes the detachable connection between the side plate m 7  and the sliding assembly through the mating between the first clamping groove and the first insertion portion m 541 . 
     As a preference of the first clamping groove, the bump is formed on the inner wall surface of the side plate m 7 , the first clamping groove is formed on the bump; or the first clamping groove is directly formed on the inner wall surface of the side plate m 7 . 
     As a deformation of the sliding assembly, the connecting piece m 54  in the sliding assembly may also be T-shaped. The T-shaped horizontal part is inserted in the first clamping groove of the side plate m 7 . Or, the connecting piece m 54  is the structure of other shapes, only its one end is fixed on the second sliding block, and the other end serves as the first insertion portion and forms a detachable connection with the side plate m 7 . As a further deformation, the sliding assembly may also be other structures, for example, the cylinder or the motor driving piece m 54  goes up and down on the mounting rack s 411  along the vertical direction, one end of the connecting piece m 54  is fixed on an extending and retracting shaft of the cylinder or the motor, and the other end is detachably connected on the side plate m 7 . 
     As a deformation of the sliding mechanism, except the above two implementation modes, the sliding structure may also be other existing sliding mechanisms, only the two side plates m 7  of the air outlet frame m 3  are arranged on the mounting rack s 411  in a sliding manner. 
     As a deformation, the structure of the air outlet frame m 3  may also be in other shapes, for example, it is U-shaped, or arc-shaped, or in other shapes, only the air outlet is formed on it; the specific shape needs to be designed according to the specific requirements of the users. 
     As a deformation, the mounting rack s 411  may also be a plate, for example, an L-shaped plate, or a T-shaped plate, or a vertical plate. As a further deformation, the mounting rack s 411  may also be other structures, only the first sliding chute m 51  or the first through hole m 53  are formed, or the guide rail may be mounted on it. The mounting rack s 411  is mounted between the base part s 101  and the panel s 412  of the air conditioner indoor unit. 
     As a deformation, the first clamping portion m 41  and the first limiting portion m 42  in the fixing assembly m 4  may also be in other shapes; for example, the first limiting portion m 42  is the first bump on which a groove is formed, the first clamping portion m 41  is the second bump which is inserted in the groove of the first bump. The first bump and the second bump may be separated only by poking the top of the first bump. 
     As shown in  FIG.  209    to  FIG.  211   , when the first through hole m 53  is formed on the side plate m 7 , as a deformation of the fixing assembly m 4 , the fixing assembly m 4  is arranged in the chamber formed between the panel s 412  and the base part s 101  and the mounting rack s 411 . Each fixing assembly m 4  includes the first limiting piece m 43  and the elastic piece mounted on one end of the first limiting piece m 43 . The other end of the first limiting piece m 43  extends to the second through hole m 10  formed on the panel s 412 . The elastic piece applies the reset force, towards the direction of the second through hole m 10 , on the first limiting piece m 43 . Under the mating between the elastic piece and the external acting force, the first limiting piece m 43  does an extending and retracting movement towards or far away from the second through hole m 10 , so as to make the first limiting piece m 43  mate with the first sliding block m 52  in a locking manner or unlock the first sliding block m 52 . The elastic piece is preferably the spring. 
     As shown in  FIG.  212   , the first limiting piece m 43  has the first strip-shaped body m 431  and the first pressing portion m 433  formed on the end face of the other end of the first strip-shaped body m 431 . There is a second clamping portion m 432  in one-to-one correspondence with the first sliding block m 52  on the surface, facing towards the mounting rack s 411 , of the first strip-shaped body m 431 . One end of the first strip-shaped body m 431  is connected to the spring, and the other faces to the second through hole m 10  facing towards the panel s 412 . The first pressing portion m 433  is suitable to pass through the second through hole m 10 . Corresponding to the second clamping portion m 432 , a second clamping groove for inserting the second clamping portion m 432  is formed on the surface, facing towards one side of the mounting rack s 411 , of the first sliding block m 52 . In order to sheath the spring on the first strip-shaped body m 431  conveniently, a first connecting portion m 434  such as a connecting piece or a connecting shaft is formed on the end, facing towards the spring, of the strip-shaped body, so as to directly sheath one end of the spring on the connecting piece or the connecting shaft. The second clamping portion m 432  is preferably the bump, and the second clamping groove is preferably the U-shaped groove. The bump is inserted in the U-shaped groove. When the function of locking the side plate m 7  needs to be disabled, it is only needed to press the first pressing portion m 433  at the second through hole m 10  toward the chamber. The first strip-shaped body m 431  moves towards the spring to separate the second clamping portion m 432  from the second clamping groove, so that the function of locking the side plate m 7  is realized, and then the side plate m 7  and the air outlet frame m 3  slide integrally in the first through hole m 53 . The acting force on the first pressing portion m 433  is withdrawn, and the first strip-shaped body m 431  extends to the second through hole m 10  under the acting force of the spring, so that the first pressing portion m 433  resets to the start position. When the second sliding block of the side plate m 7  needs to be locked, the side plate m 7  and the air outlet frame m 3  slide upwards in the first through hole m 53  to align the second clamping groove on the second sliding block with the second clamping portion m 432 , and then the second clamping portion m 432  may be inserted in the second clamping groove again, in such a manner, the function of locking the side plate m 7  is realized. In the implementation mode, the first strip-shaped body m 431  is arranged in the chamber along the width direction of the mounting rack s 411 , one end of the spring is fixed on the first strip-shaped body m 431 , and the other end is fixed on the other parts adjacent to it, such as the air duct assembly, the evaporator or the base part s 101 ; that is, the first strip-shaped body extends and retracts in the forward and backward directions of the air conditioner, and the second through hole m 10  is on the front of the air conditioner. In addition, there is the stepped face formed between the first pressing portion m 433  and the end face of the end, facing towards the second through hole m 10 , of the first pressing portion m 433 . The stepped face leans against on the inner surface of the panel s 412 . In order to enable the first limiting piece m 43  to extend and retract smoothly in the chamber, a second support m 9 , such as the sleeve structure or the U-shaped structure, is arranged in the chamber. The second support m 9  is sheathed on the first limiting piece m 43  and between two adjacent second clamping portions  432 . The second support m 9  may be fixed either on the mounting rack s 411  or in other parts. 
     As a deformation, the second through hole m 10  may also be arranged on the mounting rack s 411 , for example, the first through hole is formed on the vertical part of the L-shaped bracket, and the second through hole m 10  is formed on the horizontal part of the L-shaped bracket. Correspondingly, as shown in  FIGS.  213  to  215   , a first poking block m 435  is arranged on the top of the first strip-shaped body m 431 , and the second through hole m 10  is a long waist-shaped hole extending along the width of the mounting rack s 411 . The end, with its back to the spring, of the first strip-shaped body m 431  is in the chamber or leans against the inner surface of the panel s 412 . When the function of locking the side plate m 7  needs to be disabled, it is only needed to poke backwards the first poking block m 435  to make it move in the long waist-shaped hole, so that the first strip-shaped body is driven to retract towards the elastic body, and the second clamping portion m 432  separates from the second clamping groove. After the acting force applied on the first poking block m 435  is withdrawn, under the action of the reset force of the spring, the first poking block m 435  moves forwards in the long waist-shaped hole, so that the first limiting piece m 43  resets to the start position. In addition, the inwards-sunken groove is formed at a position on the surface of the side, facing toward the mounting rack s 411 , of the first strip-shaped body m 431 , and the position avoids the second clamping portion m 432 , so as to reduce the weight of the first strip-shaped body m 431 . In the implementation mode, the panel is tabulate. As a deformation, the panel may also be L-shaped. The horizontal part of the L-shaped panel is fixed on the inner surface of the top of the base part. The air inlet p 23  is formed on the horizontal part, and correspondingly the second through hole may also be formed on the horizontal part of the panel. Optimally, the horizontal part of the L-shaped panel is mounted on the top surface of the mounting rack, so that the panel, the base part, two side plates and the air outlet frame form the whole exterior of the air conditioner. Correspondingly, in all above implementation modes, the panel may be the L-shaped plate, or in other shapes. The air inlet p 23  is formed on the panel. 
     As a further deformation, the fixing assembly m 4  may be replaced with other buckle structures or fasteners such as screw or bolt assembly, only the side plate m 7  is fixed on the mounting rack s 411  in a detachably connecting manner. 
     As a deformation, the air sweeping mechanism m 12  may also be that in the existing air conditioner. A swaying angle of the air sweeping blade is not specifically limited but adjusted according to users&#39; requirements. As a further deformation, the air sweeping mechanism m 12  may also be not arranged on the air outlet of the air outlet frame m 3 , but arranged on the other parts in the air conditioner indoor unit, only it is close to the air outlet. 
     As a further deformation, it is unnecessary to arrange the two side plates m 7 , only the side walls of two ends of the air outlet frame m 3  are arranged on the mounting rack s 411  in a sliding manner. As a further deformation, it is unnecessary to arrange the sliding mechanism, and the air outlet frame m 3  is movably connected on the mounting rack s 411  in other fixing manners; for example, the air outlet frame m 3  is connected rotationally or reversibly on the mounting rack s 411 , and then the air outlet frame m 3  is fixed and kept between the panel s 412  and the base by using the fixing assembly m 4 . 
     As a deformation, the fixing assembly m 4  may also fix and keep the air outlet frame m 3  on the other adjacent parts, not only the base part s 101  and the panel s 412 , in the air conditioner indoor unit.
