In a related air conditioner, the air conditioner usually includes an air inlet pipe and an air outlet pipe, the air inlet pipe introduces outdoor air to exchange heat with an outdoor heat exchanger, and after heat exchange, air is discharged to the outside through the air outlet pipe. The air inlet pipe and the air outlet pipe are usually arranged in parallel and need to be independently and separately mounted on a window during mounting, so that the operation is complicated.

In order to solve the above problem, as shown in FIG. 1 and FIG. 2, some embodiments of the present disclosure provide an air conditioner, which may include a housing 1. The housing 1 may be configured as a shell outside the air conditioner. The interior of the housing 1 may be configured to provide a mounting space.

As shown in FIG. 1, in some embodiments, the housing 1 may be of a cuboid hollow structure. A longitudinal direction of the housing 1 may be arranged along a height direction, so that the air conditioner is vertically arranged in a use site, the height of the air conditioner is increased, and the space occupied by the air conditioner is reduced.

It should be noted that in other embodiments, the outer shape of the housing 1 may be designed as needed, which is not limited herein.

As shown in FIG. 1 and FIG. 3, in some embodiments, the housing 1 may include a main shell 11. The main shell 11 may be arranged in an extending manner along the height direction. A height dimension of the main shell 11 may be greater than a left-right width dimension and a front-back width dimension of the main shell 11 so as to increase the height of the housing 1 and reduce the space occupied by the housing 1.

As shown in FIG. 1 and FIG. 3, in some embodiments, the housing 1 may include a chassis 12. The chassis 12 may be disposed at a bottom of the main shell 11. An accommodating space 10 may be formed between an upper side of a top of the chassis 12 and an interior of the main shell 11. The accommodating space 10 is used as a mounting space for other devices of the air conditioners.

As shown in FIG. 1 and FIG. 3, in some embodiments, a base foot 13 may be disposed on a circumferential side of the chassis 12. The base foot 13 may be arranged in an extending manner toward an outer circumferential direction of the chassis 12, and the base foot 13 may be configured to increase the contact area between the bottom of the housing 1 and the ground to further improve the supporting stability of the chassis 12 to the air conditioner, so that the stability of the air conditioner is improved.

As shown in FIG. 1 and FIG. 3, in some embodiments, a plurality of base feet 13 may be disposed, and the plurality of base feet 13 may be connected end to end in sequence, so that the plurality of base feet 13 are arranged circumferentially around the circumferential side of the chassis 12. Thus, the plurality of base feet 13 may be arranged in an annular structure on the outer circumferential side of the chassis 12 to improve the structural strength among the plurality of base feet 13, so that an intact annular structure is formed; moreover, a user is prevented from colliding with the base feet 13, so that the use safety of the air conditioner is improved.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may be disposed in the housing 1. The refrigerant circulation loop may be disposed in the accommodating space 10. The refrigerant circulation loop may include a compressor 21, an outdoor heat exchanger 22, and an indoor heat exchanger 23 connected end to end. A refrigerant flows circularly in the refrigerant circulation loop composed of the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During circulation of the refrigerant, the outdoor heat exchanger 22 and the indoor heat exchanger 23 may serve as a condenser and an evaporator respectively, so that the refrigerant is evaporated in the evaporator to absorb heat and is condensed in the condenser to release heat, so that a refrigerating cycle or a heating cycle of the air conditioner may be executed.

Specifically, in a refrigerating cycle, the outdoor heat exchanger 22 may serve as the condenser, and the indoor heat exchanger 23 may serve as the evaporator. In a heating cycle, the outdoor heat exchanger 22 may serve as the evaporator, and the indoor heat exchanger 23 may serve as the condenser.

It should be noted that the refrigerating cycle and the heating cycle each include a series of processes with compression, condensation, expansion, and evaporation involved, and supply the refrigerant to adjusted and heat-exchanged air.

The compressor 21 is configured to compress a refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the ambient environment through the condensing process.

The evaporator evaporates the expanded refrigerant and makes the refrigerant gas in a low-temperature and low-pressure state return to the compressor 21. The evaporator may perform heat exchange with the ambient environment by means of latent heat generated by evaporation of the refrigerant to achieve a refrigerating effect.

During the whole circulation, the air conditioner may adjust the temperature of the indoor space to improve the comfort level of the indoor space and enhance the usage experience of the user.

As shown in FIG. 2, FIG. 3, and FIG. 4, in some embodiments, the air conditioner may include an outdoor fan assembly 3. The outdoor fan assembly 3 may be disposed in the housing 1. The outdoor fan assembly 3 may be arranged opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 may be configured to introduce outdoor air into the housing 1 and exchange heat with the outdoor heat exchanger 22 to form a heat exchange air flow.

For example, during the refrigerating cycle, the outdoor heat exchanger 22 serves as the condenser, and the outdoor fan assembly 3 may extract external air and blow the external air to the outdoor heat exchanger 22 to dissipate the outdoor heat exchanger 22, so as to decrease the temperature of the outdoor heat exchanger 22. During the heating cycle, the outdoor heat exchanger 22 serves as the evaporator, and the outdoor fan assembly 3 may extract external air and blow the external air to the outdoor heat exchanger 22 to heat the outdoor heat exchanger 22, so as to increase the temperature of the outdoor heat exchanger 22.

As shown in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the air conditioner may include an indoor fan assembly 4. The indoor fan assembly 4 may be disposed in the housing 1. The indoor fan assembly 4 may be arranged opposite to the indoor heat exchanger 23. The indoor fan assembly 4 may be configured to introduce indoor air into the housing 1 and exchange heat with the indoor heat exchanger 23 to form a heat exchange air flow.

For example, during the refrigerating cycle, the indoor heat exchanger 23 serves as the evaporator, and the indoor fan assembly 4 may extract indoor air outside the housing 1 and blow the indoor air to the indoor heat exchanger 23 to exchange heat with the indoor heat exchanger 23, so as to decrease the temperature of air flowing through the indoor heat exchanger 23, thereby decreasing the temperature of the indoor air.

For another example, during the heating cycle, the indoor heat exchanger 23 serves as the condenser, and the outdoor fan assembly 3 may extract indoor air outside the housing 1 and blow the indoor air to the indoor heat exchanger 23 to exchange heat with the indoor heat exchanger 23, so as to increase the temperature of air flowing through the indoor heat exchanger 23, and blow the heated air back indoors to increase the temperature of the indoor air.

As shown in FIG. 3 and FIG. 4, in some embodiments, the compressor 21, the outdoor heat exchanger 22, the outdoor fan assembly 3, the indoor heat exchanger 23, and the indoor fan assembly 4 may be respectively disposed in the accommodating space 10 inside the housing 1. Thus, the housing 1 may play the roles of covering and protecting them and preventing structural damage due to erosion of external foreign objects or impact of an external force, so as to improve the structural reliability of the air conditioner, thereby guaranteeing normal work of the air conditioner.

As shown in FIG. 3 and FIG. 4, in some embodiments, the accommodating space 10 inside the housing 1 may include three layers of sub-spaces. The three layers of sub-spaces are respectively a first sub-space 110, a second sub-space 120, and a third sub-space 130 arranged in sequence from bottom to top. The compressor 21 may be disposed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 may be disposed in the second sub-space 120. The indoor heat exchanger 23 and the indoor fan assembly 4 may be disposed in the third sub-space 130. Thus, through the three layers of sub-spaces in sequence from bottom to top, the devices such as the compressor 21, the outdoor heat exchanger 22, the outdoor fan assembly 3, the indoor heat exchanger 23, and the indoor fan assembly 4 may be arranged in a scattered manner at different height positions inside the housing 1, which is beneficial to improving the overall height of the air conditioner, reducing the width and thickness dimensions of the air conditioner, and reducing the space of the use site occupied by the air conditioner.

As shown in FIG. 2, FIG. 3, and FIG. 4, in some embodiments, an indoor air inlet 111 may be formed in an outer wall of the housing 1. The indoor air inlet 111 may communicate with the outside of the housing 1. The indoor air inlet 111 may communicate with the indoor space. The indoor air inlet 111 may be formed in an outer wall corresponding to the third sub-space 130, and the indoor air inlet 111 may be formed opposite to air inlet ends of the indoor heat exchanger 23 and the indoor fan assembly 4. Thus, when the indoor fan assembly 4 operates, the indoor fan assembly 4 may extract indoor air through the indoor air inlet 111 to enter the housing 1 and exchange heat with the indoor heat exchanger 23. The air after heat exchange is discharged to the indoor space outside the housing 1 again through the air outlet end of the indoor fan assembly 4.

As shown in FIG. 1, FIG. 3, and FIG. 4, in some embodiments, an indoor air outlet 112 may be formed in the outer wall of the housing 1. The indoor air outlet 112 may communicate with the outside of the housing 1. The indoor air outlet 112 may communicate with the indoor space. The indoor air outlet 112 may be formed in an outer wall corresponding to the third sub-space 130, and the indoor air outlet 112 may be formed opposite to an air outlet end of the indoor fan assembly 4. Thus, when the indoor fan assembly 4 operates, the indoor fan assembly 4 extracts indoor air through the indoor air inlet 111. The air exchanging heat with the indoor heat exchanger 23 may be discharged to the indoor space outside the housing 1 again through the air outlet end of the indoor fan assembly 4 and the indoor air outlet 112.

As shown in FIG. 1 and FIG. 3, in some embodiments, an air deflector 113 may be disposed outside the outer wall of the housing 1. The air deflector 113 is rotatably disposed at the indoor air outlet 112. A plurality of air deflectors 113 may be disposed, and the plurality of air deflectors 113 may be disposed at the indoor air outlet 112 in parallel. When the air deflectors 113 rotate, the air deflectors 113 may open or close the indoor air outlet 112. When the air deflectors 113 rotate to open the indoor air outlet 112, the air deflectors 113 may further change the air outlet direction of the indoor air outlet 112.

As shown in FIG. 2 and FIG. 4, in some embodiments, the air conditioner may include an air inlet pipe 14. The indoor air inlet pipe 14 may be disposed in a space outside the housing 1. The air inlet pipe 14 may be configured to introduce indoor air. One end of the air inlet pipe 14 may communicate with the air inlet end of the outdoor fan assembly 3. The other end of the air inlet pipe 14 may be configured to communicate with the outdoor space. The air outlet end of the outdoor fan assembly 3 may be arranged toward the outdoor heat exchanger 22. Thus, the outdoor fan assembly 3 may extract air in the outdoor space through the air inlet pipe 14, introduce the outdoor air into the housing 1, and blow the air to the outdoor heat exchanger 22 to heat or cool the outdoor heat exchanger 22.

As shown in FIG. 2 and FIG. 4, in some embodiments, the air conditioner may include an air outlet pipe 15. The air outlet pipe 15 may be disposed in a space outside the housing 1. The air outlet pipe 15 may be configured to discharge air to the outside to discharge the air in the housing 1 to the outside. One end of the air outlet pipe 15 may communicate with the inner space end of the housing 1. The other end of the air outlet pipe 15 may be configured to communicate with the outdoor space. Thus, when the outdoor fan assembly 3 operates, the outdoor fan assembly 3 may extract air in the outdoor space through the air inlet pipe 14, introduce the outdoor air into the housing 1, blow the air to the outdoor heat exchanger 22, and make the air flowing through the outdoor heat exchanger 22 in the housing 1 be discharged to the outdoor space through the air outlet pipe 15 to achieve outdoor air circulation.

As shown in FIG. 2 and FIG. 4, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 may be disposed on the outer side of the third sub-space 130. A receiving region 140 may be disposed in a concave manner on the outer wall of the upper portion of the housing 1 corresponding to the third sub-space 130. The air inlet pipe 14 and the air outlet pipe 15 may be arranged in the receiving region 140, so that the air inlet pipe 14 and the air outlet pipe 15 may be arranged above the second sub-space 120, and the air inlet pipe 14 and the air outlet pipe 15 may be arranged above the outdoor heat exchanger 22 and the outdoor fan assembly 3.

It is to be noted that in some other embodiments, the air inlet pipe 14 may also be configured to discharge air, and the air outlet pipe 15 may also be configured to feed air. The air outlet pipe 15 may introduce the outdoor air into the housing 1 and exchange heat with the outdoor heat exchanger 22. Air after heat exchange may be conveyed to the outside through the air inlet pipe 14 under the action of the outdoor fan assembly 3.

As shown in FIG. 2 and FIG. 4, in some embodiments, the air inlet pipe 14 and the air outlet pipe 15 may be arranged in parallel in the receiving region 140 on the outer wall of the housing 1. A lower end of the air inlet pipe 14 may communicate with the air inlet end of the outdoor fan assembly 3. A lower end of the air outlet pipe 15 may communicate with the second sub-space 120 in the housing 1. An upper end of the air inlet pipe 14 and an upper end of the air outlet pipe 15 may be connected to the outdoor space. During mounting of the air conditioner, the air inlet pipe 14 and the air outlet pipe 15 may be lengthened and mounted and fixed on the wall or window to communicate with the outdoor space.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner may include a first water collection tray 5. The first water collection tray 5 may be disposed in the accommodating space 10 in the housing 1. The first water collection tray 5 may be arranged in a region between the first sub-space 110 and the second sub-space 120. The outdoor heat exchanger 22 may be disposed above the first water collection tray 5. The first water collection tray 5 may be configured to carry condensate water flowing down from the outer wall of the outdoor heat exchanger 22. When the air conditioner heats, the refrigerant may be evaporated to absorb heat at the outdoor heat exchanger 22, so that the surface temperature of the outdoor heat exchanger 22 is decreased. Water vapor in the air is condensed to water when cooled to further fall into the first water collection tray 5 at the bottom of the outdoor heat exchanger 22 and is collected in the first water collection tray 5 or is discharged after being collected in the first water collection tray 5, which, thus, may prevent the risk of slippage of the air conditioner or people since the condensate water drops onto the ground.

As shown in FIG. 3 and FIG. 4, in some embodiments, a bottom end opening of the air outlet pipe 15 may be arranged in an upper space of the first water collection tray 5. When outdoor rainwater enters the housing 1 through the air outlet pipe 15, the rainwater may be carried by the first water collection tray 5, so that the rainwater is prevented from directly flowing to other regions in the housing 1 or seeping out of the housing 1 and flowing to the ground.

As shown in FIG. 4, in some embodiments, a drainage outlet 51 may be formed in the side wall of the first water collection tray 5. A drain valve 52 may be disposed at the drainage outlet 51. The drain valve 52 may block the drainage outlet 51. When the drain valve 52 opens the drainage outlet 51, the drainage outlet 51 may communicate with the outside of the first water collection tray 5, and water in the first water collection tray 5 may flow out of the first water collection tray 5 through the drainage outlet 51.

As shown in FIG. 2 and FIG. 4, in some embodiments, the drain valve 52 may be disposed outside the housing 1, and the drainage outlet 51 may communicate with the outside of the housing 1. When the drain valve 52 opens the drainage outlet 51, water in the first water collection tray 5 may flow out of the housing 1 through the drainage outlet 51.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner may include a second water collection tray 6. The second water collection tray 6 may be disposed in the housing 1. The second water collection tray 6 may be arranged in a region between the second sub-space 120 and the third sub-space 130. The indoor heat exchanger 23 may be disposed above the second water collection tray 6. The second water collection tray 6 may be configured to carry condensate water flowing down from the outer wall of the indoor heat exchanger 23. When the air conditioner heats, the refrigerant may be evaporated to absorb heat at the indoor heat exchanger 23, so that the surface temperature of the indoor heat exchanger 23 is decreased. Water vapor in the air is condensed to water when cooled to further fall into the second water collection tray 6 at the bottom of the indoor heat exchanger 23 and is collected in the second water collection tray 6 or is discharged after being collected in the second water collection tray 6, which, thus, may prevent the risk of slippage of the air conditioner or people since the condensate water drops onto the ground.

As shown in FIG. 3 and FIG. 4, in some embodiments, the indoor fan assembly 4 may be disposed above the second water collection tray 6. The indoor fan assembly 4 may be disposed on a transverse side of the indoor heat exchanger 23. The second water collection tray 6 may be configured to provide a mounting space for the indoor fan assembly 4, so that the indoor fan assembly 4 and the indoor heat exchanger 23 are transversely disposed adjacent to each other, and therefore, the indoor air introduced by the indoor fan assembly 4 can exchange heat with the indoor heat exchanger 23 nearby, which is beneficial to improving the heat exchange efficiency of the indoor heat exchanger 23.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner may include a housing 1. The housing 1 includes a main shell 11 and a chassis 12. The main shell 11 and the chassis 12 form an inner accommodating space 10.

The air inlet pipe 14 and the air outlet pipe 15 are disposed above the outdoor heat exchanger 22 and are spaced apart from the indoor fan assembly 4 in the horizontal direction. The compressor 21 is disposed at the bottom of the housing 1, and the second water collection tray 6 is disposed above the compressor 21.

As shown in FIG. 3 and FIG. 4, in some embodiments, the air conditioner may include a support member 7. The support member 7 may be disposed in the main shell 11. The support member 7 may be disposed in the accommodating space 10. The support member 7 may be configured to support the inner structure of the air conditioner. For example, the support member 7 may be configured to support the outdoor heat exchanger 22, the outdoor fan assembly 3, the first water collection tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the second water collection tray 6, and the like, to further improve the structural strength and structural stability inside the air conditioner.

As shown in FIG. 3 and FIG. 4, in some embodiments, a lower portion of the support member 7 may be disposed in the first sub-space 110, and a bottom end of the support member 7 may be supported and fixed on the chassis 12. The upper portion of the support member 7 may be disposed in the second sub-space 120, and a top end of the support member 7 may be supported at the bottom of the water collection tray 6, so that the indoor heat exchanger 23 and the indoor fan assembly 4 are mounted on the second water collection tray 6. The indoor heat exchanger 23 and the indoor fan assembly 4 may be supported at the top end of the support member 7 through the second water collection tray 6, so that the structural stability of the indoor heat exchanger 23 and the indoor fan assembly 4 in the third sub-space 130 is further improved.

As shown in FIG. 3 and FIG. 4, in some embodiments, the first water collection tray 5 may be supported and fixed on the upper portion of the support member 7, so that the outdoor heat exchanger 22 is mounted on the first water collection tray 5 and is supported and fixed on the support member 7 through the first water collection tray 5. The outdoor fan assembly 3 may be disposed on the upper portion of the support member 7. Thus, the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 in the second sub-space 120 may be improved.

It is to be noted that in some other embodiments, the support member 7 may also be configured to support any one or more of the outdoor heat exchanger 22, the outdoor fan assembly 3, the first water collection tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, and the second water collection tray 6. For example, the support member 7 may also be configured to independently support the outdoor heat exchanger 22 and/or the indoor heat exchanger 23.

As shown in FIG. 4, in some embodiments, the outdoor fan assembly 3 may include an outdoor air duct shell 30. An outdoor air duct may be formed in the outdoor air duct shell 30. An air outlet end of the outdoor air duct shell 30 may communicate with the outside, and an air outlet end of the outdoor air duct shell 30 may face the outdoor heat exchanger 22. Specifically, the air outlet end of the outdoor air duct shell 30 may communicate with the air inlet pipe 14 and communicate with the outdoor space through the air inlet pipe 14. The air outlet end of the outdoor air duct shell 30 may be arranged toward the outdoor heat exchanger 22. Thus, an air duct in the outdoor air duct shell 30 may extract air in the outdoor space through the air inlet pipe 14, introduce the outdoor air into the housing 1, and blow the air to the outdoor heat exchanger 22 to heat or cool the outdoor heat exchanger 22.

As shown in FIG. 4, in some embodiments, the outdoor air duct shell 30 may include a volute component 31. The volute component 31 may be fixed on the support member 7. The air duct in the outdoor air duct shell 30 may be formed in the volute component 31.

The volute component 31 may be fixed on the volute portion 71, so that the volute component 31 is fixed on the support member 7. The volute component 31 and the volute portion 71 may be spliced to form the volute structure, and an outdoor air duct may be formed in the volute structure. That is, the volute component 31 and the volute portion 71 may be spliced to form an intact outdoor air duct shell 30. The volute structure is provided with an air inlet end and an air outlet end. The air inlet end of the volute structure communicates with the air inlet pipe 14 to further communicate with the outdoor space. The air outlet end of the volute structure communicates with the second sub-space 120 and is arranged toward the outdoor heat exchanger 22.

It is to be noted that in some other embodiments, the outdoor air duct shell 30 may be formed by splicing two oppositely arranged volute components 31 in an abutted manner. The spliced outdoor air duct shell 30 may also be detachably fixed on the support member 7. Alternatively, the outdoor air duct shell 30 may also be an intact volute component 31.

As shown in FIG. 7, FIG. 15, and FIG. 16, in some embodiments, the air conditioner may include an air duct fixing member 18. The air duct fixing member 18 may be configured to relatively fix the air inlet pipe 14 and the air outlet pipe 15 to solve the fixing problem of the air inlet pipe 14 and the air outlet pipe 15, so as to prevent the air inlet pipe 14 and the air outlet pipe 15 from intertwining with each other.

As shown in FIG. 7, FIG. 15, and FIG. 16, in some embodiments, the air duct fixing member 18 may include a fixed portion 181. The fixed portion 181 may be disposed between the air inlet pipe 14 and the air outlet pipe 15. The fixed portion 181 may be clamped in a region between the air inlet pipe 14 and the air outlet pipe 15. The air inlet pipe 14 and the air outlet pipe 15 are respectively fixed on two opposite sides of the fixed portion 181.

As shown in FIG. 7, FIG. 15, and FIG. 16, in some embodiments, the air duct fixing member 18 may include a first fixing strip 182. The first fixing strip 182 may be disposed in a stripe-like structure. A first end of the first fixing strip 182 may be fixedly connected to one end of the fixed portion 181. The first fixing strip 182 may be disposed around the outer circumference of the air inlet pipe 14. A second end of the first fixing strip 182 may be snap-fitted on the other end of the fixed portion 181. Thus, the first fixing strip 182 and the fixed portion 181 enclose a first fixing ring 180a, the first fixing ring 180a is sleeved on the outer circumference of the air inlet pipe 14, and the air inlet pipe 14 is fixed in the first fixing ring 180a, so that the air inlet pipe 14 is clamped in a region between the first fixing strip 182 and the fixed portion 181. Thus, through the cooperation of the first fixing strip 182 and the fixed portion 181, the fixing problem of the air inlet pipe 14 may be solved, so that the structural stability of the air inlet pipe 14 is improved.

It is to be noted that the first end of the first fixing strip 182 is a fixed end fixedly connected to the fixed portion 181 integrally. Before the air inlet pipe 14 is fixed, the second end of the first fixing strip 182 is a free end. When the air inlet pipe 14 is fixed, the second end of the first fixing strip 182 is snap-fitted on the other end of the fixed portion 181, so that the second end of the first fixing strip 182 is fixedly connected to the fixed portion 181 to form the first fixing ring 180a.

As shown in FIG. 7, FIG. 15, and FIG. 16, in some embodiments, the air duct fixing member 18 may include a second fixing strip 183. The second fixing strip 183 may be disposed in a stripe-like structure. A first end of the second fixing strip 183 may be fixedly connected to one end of the fixed portion 181. The second fixing strip 183 may be disposed around the outer circumference of the air outlet pipe 15. A second end of the second fixing strip 183 may be snap-fitted on the other end of the fixed portion 181. Thus, the second fixing strip 183 and the fixed portion 181 enclose a second fixing ring 180b, the second fixing ring 180b is sleeved on the outer circumference of the air outlet pipe 15, and the air outlet pipe 15 is fixed in the second fixing ring 180b, so that the air outlet pipe 15 is snap-fitted in a region between the second fixing strip 183 and the fixed portion 181. Thus, through the cooperation of the second fixing strip 183 and the fixed portion 181, the fixing problem of the air outlet pipe 15 may be solved, so that the structural stability of the air outlet pipe 15 is improved. In addition, the fixed portion 181 matches the first fixing strip 182 and the second fixing strip 183 to respectively fix the air inlet pipe 14 and the air outlet pipe 15 on two opposite sides of the fixed portion 181 to solve the relative fixing problem of the air inlet pipe 14 and the air outlet pipe 15, so as to prevent the air inlet pipe 14 and the air outlet pipe 15 from intertwining with each other during mounting or movement.

It is to be noted that the first end of the second fixing strip 183 is a fixed end fixedly connected to the fixed portion 181 integrally. Before the air outlet pipe 15 is fixed, the second end of the second fixing strip 183 is a free end. When the air outlet pipe 15 is fixed, the second end of the second fixing strip 183 is snap-fitted on the other end of the fixed portion 181, so that the second end of the second fixing strip 183 is fixedly connected to the fixed portion 181 to form the second fixing ring 180b.

As shown in FIG. 7, FIG. 17, and FIG. 18, in some embodiments, the first fixing strip 182 may be provided with a first bent portion 184. The first bent portion 184 may be disposed in a protruding manner toward an outer circumferential side of the first fixing strip 182. The first bent portion 184 has an elastic deformation function. The first bent portion 184 is capable of deforming elastically in the circumferential direction of the first fixing ring 180a to change the perimeter of the first fixing ring 180a. Thus, when the first fixing strip 182 is disposed around the outer circumference of the air inlet pipe 14, the diameter of the first fixing ring 180a formed by the first fixing strip 182 and the fixed portion 181 may be automatically adjusted to fit air inlet pipes 14 with different diameter dimensions. For example, for a diameter difference of the air inlet pipe 14 due to either manufacturing errors or different models, the diameter of the air inlet pipe 14 may be fixed by the first fixing strip 182 of the air duct fixing member 18. Specifically, when the second end of the first fixing strip 182 is snap-fitted on one end of the fixed portion 181, the second end of the first fixing strip 182 is capable of applying a tensile force to the first bent portion 184, so that the first bent portion 184 is capable of deforming elastically in the circumferential direction of the first fixing ring 180a to change the perimeter of the first fixing ring 180a and automatically adjust the diameter of the first fixing ring 180a, and thus, the first fixing strip 182 and the fixed portion 181 are stably snap-fitted on the outer circumference of the air inlet pipe 14.

It is to be noted that when the second end of the first fixing strip 182 is separated from one end of the fixed portion 181, the tensile force applied to the first bent portion 184 disappears, and the first bent portion 184 is capable of deforming to restore.

As shown in FIG. 7, FIG. 17, and FIG. 18, in some embodiments, the first fixing strip 182 may be provided with a first opening region 1820.

One end of the first connecting section 1843 may be in bent connection to one end of the first extended section 1841 away from the first opening end 1821, i.e., one end of the first connecting section 1843 may be in bent connection to an outer end of the first extended section 1841. The other end of the first connecting section 1843 may be in a bent connection to one end of the second extended section 1842 away from the second opening end 1822, i.e., the other end of the first connecting section 1843 may be in a bent connection to an outer end of the second extended section 1842. The first opening region 1820 may be formed in a region among the first connecting section 1843, the first extended section 1841, and the second extended section 1842.

Specifically, when the second end of the first fixing strip 182 is snap-fitted on one end of the fixed portion 181, the second end of the first fixing strip 182 is capable of applying a tensile force to the first bent portion 184, so that the first connecting section 1843, the first extended section 1841, and the second extended section 1842 are capable of deforming elastically in the circumferential direction of the first fixing ring 180a to change the included angle between the first connecting section 1843 and the first extended section 1841 and the included angle between the first connecting section 1843 and the second extended section 1842 to further change the distance between the first opening end 1821 and the second opening end 1822, so as to change the perimeter of the first fixing ring 180a.

The second bent portion 185 may be disposed in a protruding manner toward an outer circumferential side of the second fixing strip 183. The second bent portion 185 has an elastic deformation function. The second bent portion 185 is capable of deforming elastically in the circumferential direction of the second fixing ring 180b to change the perimeter of the second fixing ring 180b. Thus, when the second fixing strip 183 is disposed around the outer circumference of the air outlet pipe 15, the diameter of the second fixing ring 180b formed by the second fixing strip 183 and the fixed portion 181 may be automatically adjusted to fit air outlet pipes 15 with different diameter dimensions. For example, for a diameter difference of the air outlet pipe 15 due to either manufacturing errors or different models of the air outlet pipe 15, the diameter of the air outlet pipe 15 may be fixed by the second fixing strip 183 of the air duct fixing member 18. Specifically, when the second end of the second fixing strip 183 is snap-fitted on one end of the fixed portion 181, the second end of the second fixing strip 183 is capable of applying a tensile force to the second bent portion 185, so that the second bent portion 185 is capable of deforming elastically in the circumferential direction of the second fixing ring 180b to change the perimeter of the second fixing ring 180b and automatically adjust the diameter of the second fixing ring 180b, and thus, the second fixing strip 183 and the fixed portion 181 are stably snap-fitted on the outer circumference of the air outlet pipe 15.

It is to be noted that when the second end of the second fixing strip 183 is separated from one end of the fixed portion 181, the tensile force applied to the second bent portion 185 disappears, and the second bent portion 184 is capable of deforming to restore.

As shown in FIG. 7, FIG. 17, and FIG. 18, in some embodiments, the second fixing strip 183 may be provided with a second opening region 1830.
