     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The technical solutions of the embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. It is obvious that the embodiments to be described are only some rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of the present disclosure. 
     It should be noted that if there is a directional indication (such as up, down, left, right, front, rear . . . ) in the embodiments of the present disclosure, the directional indication is only used to explain the relative positional relationship, movement, etc. of the components in a certain posture (as shown in the drawings). If the specific posture changes, the directional indication will change accordingly. 
     Besides, the descriptions associated with, e.g., “first” and “second,” in the present disclosure are merely for descriptive purposes, and cannot be understood as indicating or suggesting relative importance or impliedly indicating the number of the indicated technical feature. Therefore, the feature associated with “first” or “second” can expressly or impliedly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the realization of those of ordinary skill in the art. When the combination of technical solutions is contradictory or cannot be achieved, it should be considered that such a combination of technical solutions does not exist, nor is it within the scope of the present disclosure. 
       FIG.  1    to  FIG.  17    are the drawings of the description of the mobile air conditioner of the present disclosure. The present disclosure provides a mobile air conditioner capable of cooling or heating an indoor environment to adjust the temperature of the indoor environment. The mobile air conditioner adopts a new method for installing the drain valve, which can reduce the corrosion caused by the use of screws and improve the stability for installing the drain valve. 
     In an embodiment, the mobile air conditioner includes a housing, and an indoor heat exchanger and an outdoor heat exchanger installed in the housing. An outdoor heat exchange chamber and an indoor heat exchange chamber located above the outdoor heat exchange chamber are provided inside the housing. The outdoor heat exchanger is installed in the outdoor heat exchange chamber. The indoor heat exchanger is installed in the indoor heat exchange chamber. 
     When the mobile air conditioner is cooling the indoor environment, the air in the indoor environment enters the indoor heat exchange chamber, and after heat exchange by the indoor heat exchanger, cold air is generated and blown out to the indoor environment to cool the indoor environment. At the same time, the air in the indoor environment or the outdoor environment enters the outdoor heat exchange chamber, and after heat exchange by the outdoor heat exchanger, hot air is generated and finally discharged to the outdoors through the exhaust pipe. 
     As shown in  FIG.  1    and  FIG.  2   , in an embodiment, the mobile air conditioner includes a housing and a wire control assembly  800 . An electric control box is provided in the housing, and the wire control assembly  800  is installed on the housing. The wire control assembly  800  includes a wire controller  810  and an adapter  820  for adapting the wire controller  810  (as shown in  FIG.  11   ). The adapter  820  is installed on the housing, and the adapter  820  is connected to the electric control box through the wire  822 . The wire controller  810  is located outside the housing, and the wire controller  810  is connected to the connection end  821 . 
     The housing includes a chassis  100  and a cover mounted at the chassis  100 . The adapter  820  of the wire control assembly  800  may be installed on the cover or the chassis  100 , as long as the connection end of the adapter  820  is exposed outside the housing. That is, the remote control  810  is also located outside the housing. Therefore, the operator can connect the wire controller  810  to the adapter  820  on the outside of the housing, without disassembling the housing, and without being blocked by other components, which greatly reduces the difficulty of disassembling and assembling the wire controller  810 , and is convenient for the user to check the wire controller  810 . By checking the wire controller  810 , the user can determine whether the wire controller  810  is faulty or the electric control box is faulty, and then determine whether to disassemble the housing. 
     The wire controller  810  and the adapter  820  of the wire control assembly  800  are common in the current market. When the wire control assembly  800  is working, the wire controller  810  can receive the command signal sent by the remote controller or other control terminal through WiFi, and the command signal is transmitted to the electric control box connected to the wire controller  810  through the adapter  820 . After receiving the command signal, the electric control box may control the corresponding electrical components to perform operations corresponding to the signal. The control terminal that sends out the remote control signal through WiFi may be a mobile phone, a computer, or the like. Therefore, the mobile air conditioner does not need to be equipped with a remote control, or when the remote control fails or is lost, the control terminal can send the remote control signal through WiFi to control the operation of the mobile air conditioner. 
     In technical solutions of the present disclosure, the wire control assembly  800  is provided at the mobile air conditioner. The wire control assembly  800  includes the wire controller  810  and the adapter  820  for adapting the wire controller  810 . The wire controller  810  is connected to the electric control box through the adapter  820 . The mobile air conditioner can receive the remote control signal from the remote control or other control terminal through WiFi, and there is no need to be equipped with the remote control, or when the remote control fails or is lost, the control terminal can send the remote control signal through WiFi to control the operation of the mobile air conditioner. 
     As shown in  FIG.  4    to  FIG.  6   , in an embodiment, in order to maintain and repair the wire controller  810 , the wire controller  810  may be provided outside the housing, which not only facilitates the user to disassemble and assemble the wire controller  810  on the outside, so as to repair or replace the wire controller  810 . Besides, since the wire controller  810  is not easily blocked by the housing of the mobile air conditioner or its internal components, the wire controller  810  is easier to receive the remote control command signal, which improves the signal receiving efficiency of the wire controller  810 . The housing includes a chassis  100  and a cover (not shown) mounted at the chassis  100 , and the wire controller  810  may be disposed outside the chassis  100  or outside the housing. 
     As shown in  FIG.  6    to  FIG.  8   , the wire controller  810  may be provided at the chassis  100 . The chassis  100  includes a bottom plate  110  and a side plate  120  provided along the periphery of the bottom plate  110 . A lower surface of the bottom plate  110  is provided with a mounting plate  190 . The adapter  820  is mounted at the mounting plate  190 , and a connection end  821  of the adapter  820  extends toward a side of the chassis for connecting the wire controller  810 . The mounting plate  190  is provided at the lower surface of the bottom plate  110 . Therefore, when installing the remote control  810 , the operator can extend the remote control  810  to the mounting plate  190  under the chassis  100  from one side of the chassis  100  (such as the front side, the rear side, the left side, the right side), and the wire controller  810  can be inserted into the connection end  821  of the adapter  820 . 
     As shown in  FIG.  8    to  FIG.  10   , the bottom plate  110  is provided with a wiring channel  900  for a wire of the adapter  820  to pass through, an opening is formed at a lower end of the wiring channel  900 , and the opening is located at a side of the mounting plate  190  away from the wire controller  810 . That is, for the same side plate  120  of the chassis  100 , the mounting plate  190  is closer to the side plate  120  than the wiring channel  900 , which is convenient for the operator to connect the wire controller  810  with the adapter  820  nearby. 
     Since the position where the wire controller  810  and the adapter  820  are connected is located at the open side of the mounting plate  190  away from the wiring channel  900 , even if the condensed water of the water receiving groove  101  or the outdoor heat exchanger or its surrounding components falls into the wiring channel  900 , the condensed water will be blocked by the mounting plate  190 , and will not fall to the position where the wire controller  810  and the adapter  820  are connected. That is, the mounting plate  190  can be used as a water blocking plate for the wire controller  810 , to effectively waterproof the wire controller  810 . 
     When installing the wire control assembly  800 , the adapter  820  of the wire control assembly  800  may extend from the side of the mounting plate  190  corresponding to the opening to the side away from the opening (and vice versa), and the adapter  820  is fixedly connected to the mounting plate  190 . The connection end  821  of the adapter  820  is located at the side, that faces away from the opening, of the mounting plate  190 . A wire  822  may extend from the end of the adapter  820  away from the connection end  821 . The wire  822  may extend upwards into the wiring channel  900  from the opening at the lower end of the wiring channel  900 , and then pass through the upper end of the wiring channel  900  and is connected to the electric control box. The wire controller  810  is connected to the connection end  821  of the adapter  820  on the side of the mounting plate  190  facing away from the opening at the lower end of the wiring channel  900 . 
     As shown in  FIG.  8    to  FIG.  10   , the upper surface of the bottom plate  110  may produce condensed water. To avoid the condensed water dripping from the wiring channel  900  to the floor of the room, in an embodiment, a channel enclosure plate  910  protrudes from the upper surface of the bottom plate  110 , the channel enclosure plate  910  encloses to form the wiring channel  900 , and a wire outlet hole  911  is provided at a side wall of the channel enclosure plate  910 , for the wire  822  of the adapter  820  to pass through the wiring channel  900 . The wire  822  is passed out and then connected to the electric control box. 
     The channel enclosure plate  910  is close to the water receiving groove of the chassis, and the channel enclosure plate  910  is provided with the wire outlet hole  911  on the side wall away from the water receiving groove  101 . The opening at the upper end of the channel enclosure plate  910  can be provided with a cover plate or covered by the electrical appliance protective cover  500 . When there is water on the upper surface of the bottom plate  110 , the water will be blocked by the channel enclosure plate  910 , and will be difficult to flow into the wiring channel  900 , thereby avoiding a water leakage accident and causing trouble to users. 
     As shown in  FIG.  8   ,  FIG.  10    and  FIG.  11   , in an embodiment, in order to facilitate passing the adapter  820  out of the mounting plate  190 , the mounting plate  190  is provided with an extension port  191  for the adapter  820  to pass through. The adapter  820  may be fixed with the extension port  191  by interference fit, or a positioning structure can be provided between the adapter  820  and the extension port  191  to fix the adapter  820  in the extension port  191 . In an embodiment, a first positioning block  823  protrudes from a top surface of the adapter  820  at a position away from the connection end of the adapter  820 , and the first positioning block  823  is configured to abut against a periphery, that faces the opening, of the extension port  191  after the connection end  821  of the adapter  820  protrudes from the extension port  191 . The first positioning block  823  protrudes from the side surface of the adapter  820 . 
     When installing the adapter  820 , the connection end  821  of the adapter  820  extends from the inner side (i.e., the side of the extension port  191  corresponding to the opening) of the extension port  191  to the outer side (i.e., the side of the extension port  191  facing away from the opening) of the extension port  191  until after the connection end  821  completely protrudes from the outer side of the extension port  191 , the first positioning block  823  on the adapter  820  abuts against the inner periphery of the extension port  191 , so that the adapter  820  cannot continue to pass through the extension port  191 . Since the center of gravity of the adapter  820  tends to fall on the outer side of the mounting plate  190 , the connection end  821  of the adapter  820  has a downward slope. The connection end of the adapter  820  has a tendency to incline upward, but is resisted by the first positioning block  823  and the inner periphery of the extension port  191 , so that the adapter  820  is not easy to fall out from the extension port  191 . 
     Further, in order to improve the stability of installing the adapter  820 , in an embodiment, each side of the adapter  820  is provided with a second positioning block  824 , the second positioning block  824  extends from the extension port  191  along with the connection end  821  of the adapter  820 , and is configured to abut against the periphery of the extension port  191  away from the opening. The second positioning block  824  protrudes from the side surface of the adapter  820 . 
     After the adapter  820  is installed at the extension port  191 , the first positioning block  823  may abut against the inner periphery of the extension port  191 , and the second positioning block  824  may abut against the outer periphery of the extension port  191 , thereby limiting the movement of the adapter  820  along the inward and outward direction of the extension port  191 . Under the action of no strong external force, the adapter  820  is not easy to fall out from the extension port  191 . When the adapter  820  needs to be disassembled, a strong force is applied to the adapter  820  to overcome the resistance of the first positioning block  823  or the second positioning block  824 , and the adapter  820  can be removed. 
     In an embodiment, the second positioning block  824  is provided with a front guide surface  8241  extending in a slope shape from a top of the second positioning block  824  toward the connection end  821  of the adapter  820 . During the process of passing the adapter  820  from the inner side of the extension port  191  to the outer side of the extension port  191 , the side edge of the extension port  191  slides along the front guide surface  8241  of the second positioning block  824 , to reduce the resistance of the second positioning block  824  to the installation of the adapter  820 , and reduce the difficulty of installing the adapter  820  to the extension port  191 . 
     In addition, the second positioning block  824  may also be provided with a rear guide surface  8242  extending in a slope shape from a top of the second positioning block  824  away from the connection end of the adapter  820 . During the process of disassembling the adapter  820  from the outer side of the extension port  191  to the inner side of the extension port  191 , the side edge of the extension port  191  slides along the rear guide surface  8242  of the second positioning block  824 , to reduce the resistance of the second positioning block  824  to the disassembly of the adapter  820 , and reduce the difficulty of disassembling the adapter  820 . 
     An angle is formed between the front guide surface  8241  of the second positioning block  824  and the rear guide surface  8242  of the second positioning block  824 . A top portion that can abut against the outer periphery of the extension port  191  is formed at the angle position between the front guide surface  8241  and the rear guide surface  8242 . The angle between the front guide surface  8241  and the rear guide surface  8242  may be 80° to 120°, such as but not limited to 85°, 90°, 95°, 100°, 105°, 110°, 115°, or the like. 
     In an embodiment, the wire controller  810  is inserted in and connected to the connection end  821  of the adapter  820 . In order to enhance the firmness of the connection between the wire controller  810  and the adapter  820 , in an embodiment, two opposite sides of the remote controller  810  are provided with positioning grooves  811  with forward openings, and the positioning grooves  811  are inserted into the second positioning blocks  824 . When the wire controller  810  is inserted into the connection end  821  of the adapter  820 , the positioning groove  811  on the wire controller  810  is aligned with the second positioning block  824 . After the wire controller  810  is inserted into the connection end  821  of the adapter  820 , the second positioning block  824  just enters the positioning groove  811 , and the two fit together to define the wire controller  810 . 
     Further, a third positioning block  825  protrudes from the top surface of the adapter  820  at a position close to the connection end  821  of the adapter  820 , an elastic buckle  812  is provided at the wire controller  810 , and the elastic buckle  812  is configured to buckle and fix with the third positioning block  825  after the wire controller  810  is inserted in and connected to the connection end  821 . That is, after the insertion of the wire controller  810  and the connection end  821  of the adapter  820  is completed, the elastic buckle  812  of the wire controller  810  is just fastened to the third positioning block  825  of the adapter  820 . In this way, the wire controller  810  is further fixedly connected to the adapter  820 , which greatly improves the firmness of the installation of the wire controller  810 , and the wire controller  810  does not easily fall off. 
     As shown in  FIG.  9   , based on any of the above embodiments, the chassis  100  is provided with a water receiving groove  101  and an installation position  105  for a compressor to be installed. The chassis  100  is configured to form an electrical appliance accommodation area  106  between the water receiving groove  101  and the installation position  105 , and the electrical appliance accommodation area  106  is configured for accommodating and installing an electrical component. 
     The water receiving groove  101  on the chassis  100  is located below the outdoor heat exchanger for receiving the condensed water generated by the outdoor heat exchanger. Generally, a large vacant area is formed between the water receiving groove  101  and the installation position  105  for the compressor to be installed, so that the vacant area may form an electrical appliance accommodation area  106 , for accommodating and installing the power supply components, making full use of the internal space of the mobile air conditioner and effectively regulating the distribution of the internal components of the mobile air conditioner. The wiring channel  900  is close to or within the electrical appliance accommodation area  106 . After the wires of the adapter  820  are extended out of the wiring channel  900 , the wires of the adapter  820  and the wires of the electrical components in the electrical appliance accommodation area  106  form a wiring harness and are connected to the electric control box together. 
     As shown in  FIG.  9    and  FIG.  12   , in an embodiment, the mobile air conditioner further includes an electrical appliance protective cover  500 . The electrical appliance protective cover  500  is provided in the electrical appliance accommodation area  106  and is configured to cover the electrical component and/or the wiring channel in the electrical appliance accommodation area  106 . 
       FIG.  15    to  FIG.  17    are schematic structural views of the electrical appliance protective cover  500  from different perspectives. The electrical appliance protective cover  500  can not only prevent the water droplets inside the mobile air conditioner from falling on the electrical components or the wiring channel  900 , but also prevent the electrical components or the wires in the wiring channel  900  from being damp and causing leakage or damage. Moreover, surrounding components can also be prevented from colliding or being squeezed against the wiring channel  900  or the electrical components. The electrical components may be any one or more of the first water level detector  710 , the second water level detector  720 , the water pumping motor  620 , and the drain valve  400 , which will be described in detail in the following embodiments. 
     As shown in  FIG.  9    and  FIG.  12   , in an embodiment, the electrical component further includes a first water level detector  710 . The first water level detector  710  is installed in the electrical appliance accommodation area  106  to detect a first water level in the electrical appliance accommodation area  106 , and feed the first water level signal back to the control device of the mobile air conditioner, and then the control device may receive the first water level signal for alarm or drainage. 
     Since the electrical appliance protective cover  500  covers the first water level detector  710  in its interior, it is difficult for maintenance personnel to view the first water level detector  710  from the outside of the electrical appliance protective cover  500  due to the obstructed view, so the electrical appliance protective cover  500  needs to be removed to inspect the first water level detector  710 , and the operation is cumbersome. In view of this, in order to solve this problem, a side wall of the electrical appliance protective cover  500  is provided with a first notch  501 , and the first notch  501  is configured to check the first water level detector  710 . 
     Thus, the maintenance personnel can check whether the first water level detector  710  works normally through the first notch  501  of the electrical appliance protective cover  500 . The maintenance personnel determine whether it is necessary to remove the electrical appliance protective cover  500  according to the structure viewed from the first notch  501 , to reduce useless operations during the inspection process. For example, the maintenance personnel finds that the first water level detector  710  is not working normally, an inspection tool can extend into the electrical appliance protective cover  500  from the first notch  501  to repair the first water level detector  710 ; or the electrical appliance protective cover  500  is opened to repair or replace the first water level detector  710 . 
     As shown in  FIG.  9   ,  FIG.  13    and  FIG.  14   , the side plate  120  of the chassis  100  is provided with an overflow port  126 , the overflow port  126  is close to the low water level detector, and the lower edge of the overflow port  126  is flush with the surface of the bottom plate  110  of the chassis  100 . That is to say, the lower edge of the overflow port  126  is equivalent to the lowest overflow water level of the overflow port  126 . The minimum overflow water level is flush with the upper surface of the bottom plate  110 . Once the bottom plate  110  accumulates water, the water can be discharged from the overflow port  126  in time, to prevent the chassis  100  from accumulating a lot of water, thereby greatly improving the waterproof effect of the mobile air conditioner. 
     In an embodiment, the electrical component further includes a second water level detector  720 . The second water level detector  720  is installed in the electrical appliance accommodation area  106  to detect a second water level in the electrical appliance accommodation area  106 . The second water level detector  720  is spaced apart from the first water level detector  710 . The second water level is higher than the first water level. When the second water level detector  720  is working, the second water level detector  720  feeds the second water level signal back to the control device of the mobile air conditioner, and then the control device receives the second water level signal for alarm or drainage. 
     It should be noted that the first water level detector  710  is used as a first water level defense line to protect the minimum water level required by the safety regulations of the electrical components, to prevent the electrical components from being immersed in water. The second water level detector  720  is used as a second water level defense line to protect the highest water level of the chassis to avoid overflowing water from the periphery of the chassis. The first water level detector  710  and the second water level detector  720  are switched for use in different environments. In order to facilitate the maintenance personnel to check the second water level detector  720 , the side wall of the electrical appliance protective cover  500  is provided with a second notch  502 , and the second notch  502  is configured to check the second water level detector  720 . A support leg  540  is formed between the second notch  502  and the first notch  501  of the electrical appliance protective cover  500 . 
     Thus, the maintenance personnel can check whether the second water level detector  720  works normally through the second notch  502  of the electrical appliance protective cover  500 . The maintenance personnel determine whether it is necessary to remove the electrical appliance protective cover  500  according to the structure viewed from the second notch  502 , to reduce useless operations during the inspection process. For example, the maintenance personnel finds that the second water level detector  720  is not working normally, an inspection tool can extend into the electrical appliance protective cover  500  from the second notch  502  to repair the second water level detector  720 ; or the electrical appliance protective cover  500  is opened to repair or replace the second water level detector  720 . 
     As shown in  FIG.  9   ,  FIG.  13    and  FIG.  16   , in an embodiment, the electrical component includes a water pumping motor  620  located at a side of the water receiving groove  101 , and the water pumping motor  620  is connected to the water pumping wheel  610  disposed in the water receiving groove  101  to drive the water pumping wheel  610  to work. The water pumping motor  620  and the water pumping wheel  610  constitute the water pumping assembly  600  of the mobile air conditioner. The water pumping motor  620  drives the water pumping wheel  610  to rotate, and the water pumping wheel  610  beats and transports the water in the water receiving groove  101  to the outdoor heat exchanger, to improve the heat exchange efficiency of the outdoor heat exchanger. 
     A third notch  503  is provided at the side wall of the electrical appliance protective cover  500  facing the water pumping wheel  610 , and the third notch  503  corresponds to the water pumping motor  620  for checking the water pumping motor  620 . Thus, the maintenance personnel can check whether the water pumping motor  620  works normally through the third notch  503  of the electrical appliance protective cover  500 . The maintenance personnel determine whether it is necessary to remove the electrical appliance protective cover  500  according to the structure viewed from the third notch  503 , to reduce useless operations during the inspection process. For example, the maintenance personnel finds that the water pumping motor  620  is not working normally, an inspection tool can extend into the electrical appliance protective cover  500  from the third notch  503  to repair the water pumping motor  620 ; or the electrical appliance protective cover  500  is opened to repair or replace the water pumping motor  620 . 
     As shown in  FIG.  3   ,  FIG.  9    and  FIG.  15   , in an embodiment, the electrical component further includes a drain valve  400 . The drain valve  400  is installed in the electrical appliance accommodation area  106  to open and close a water outlet of the water receiving groove  101 . 
     After the drain valve  400  opens the water outlet, the water in the water receiving groove  101  flows out of the water outlet, then enters the drainpipe under the chassis  100 , and finally drains out from the drainpipe. A fourth notch  504  is opened on a side, away from the water receiving groove  101 , of the electrical appliance protective cover  500 , and the fourth notch  504  corresponds to the drain valve  400 , to check the drain valve  400 . 
     Thus, the maintenance personnel can check whether the drain valve  400  works normally through the fourth notch  504  of the electrical appliance protective cover  500 . The maintenance personnel determine whether it is necessary to remove the electrical appliance protective cover  500  according to the structure viewed from the fourth notch  504 , to reduce useless operations during the inspection process. For example, the maintenance personnel finds that the drain valve  400  is not working normally, an inspection tool can extend into the electrical appliance protective cover  500  from the fourth notch  504  to repair the drain valve  400 ; or the electrical appliance protective cover  500  is opened to repair or replace the drain valve  400 . 
     Further, a top surface of the electrical appliance protective cover  500  corresponding to the drain valve  400  is provided with a wire passage hole  505 , and the wire passage hole  505  is configured for the connection wire of the drain valve  400  to pass through. The drain valve  400  is provided with a wiring terminal  412 , and the wire of the wiring terminal  412  is drawn out from the wire passage hole  505 . If the wire of the drain valve  400  is passed through the wire passage hole  505  inside the electrical appliance protective cover  500 , it will be difficult to pass the wire due to the obstruction of the line of sight. The fourth notch  504  extends from the lower edge of the side wall of the electrical appliance protective cover  500  to the wire passage hole  505 . In this way, the wire of the drain valve  400  can protrude laterally from the fourth notch  504  and then be inserted into the wire passage hole  505  along the fourth notch  504 , which greatly reduces the difficulty of passing the wire. 
     In order to prevent the wire from falling off from the fourth notch  504 , in an embodiment, a winding post  550  protrudes from a top surface of the electrical appliance protective cover, and the winding post  550  is configured to be surrounded by the wire passing through the wire passage hole  505 , to position the wire on the winding post  550 , so that the wire is not easy to be moved, and is difficult to escape from the fourth notch  504 . When in use, the wire of the drain valve  400  extends from the fourth notch  504  to the wire passage hole  505 , and is wound around the winding post  550  (wound in one or more turns), then is fixed to the clip on a side of the winding post  550 , and finally connected to the electric control box. 
     As shown in  FIG.  13   , and  FIG.  15    to  FIG.  17   , based on any one of the above embodiments, one end of the electrical appliance protective cover  500  is configured with a fixation member located at a side of the support plate  530 , another end of the electrical appliance protective cover  500  is further configured with an insertion member  510 , the chassis  100  is configured with an insertion part  118  and a fixation part  119 , the insertion part  118  is inserted in and connected to the insertion member  510 , and the fixation part  119  is fixedly connected to the fixation member  520 . 
     The insertion part  118  of the chassis  100  is provided with a socket for inserting the insertion member of the electrical appliance protective cover  500 . When installing the electrical appliance protective cover  500 , the insertion member  510  of the electrical appliance protective cover  500  is firstly inserted into the socket of the insertion part  118  of the chassis  100 , to pre-position the electrical appliance protective cover  500 . Then, the fixation member of the electrical appliance protective cover  500  is fixedly connected to the fixation part  119  of the chassis  100  by passing through connecting members (such as screws), to fix the electrical appliance protective cover  500  to the chassis  100 , the installation operation is simple and fast, and the assembly efficiency is high. It is worth mentioning that the connecting member may be a screw, and the fixation part  119  of the chassis  100  is a threaded post. 
     Further, a support plate  530  is configured to protrude laterally from one end of the electrical appliance protective cover  500 , the support plate  530  is adjacent to the fixation member, the support plate  530  is supported on the upper end of the channel enclosure plate  910  of the bottom plate  110  to cover the opening of the channel enclosure plate  910 , that is, the opening at the upper end of the wiring channel  900 . 
     That is to say, the channel enclosure plate  910  can support the electrical appliance protective cover  500  through the support plate  530 , and the support plate  530  may cover the upper edge of the channel enclosure plate  910 , and also covers the opening at the upper end of the wiring channel  900 . Therefore, the water inside the mobile air conditioner is not easy to fall into the floor of the room from the opening at the upper end of the wiring channel  900 . In addition, due to the existence of the opening at the upper end of the wiring channel  900 , it is also convenient for the chassis  100  to be ejected from the mold, thereby reducing the difficulty of ejection. 
     The above are only some embodiments of the present disclosure, and do not limit the scope of the present disclosure thereto. Under the inventive concept of the present disclosure, equivalent structural transformations made according to the description and drawings of the present disclosure, or direct/indirect application in other related technical fields are included in the scope of the present disclosure.
