Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] An air conditioner is a device used to regulate indoor air temperature, humidity, airflow speed, and air cleanliness. It is widely used in homes, offices, commercial spaces, and industrial environments. Its basic principle is to transfer heat through the circulation of refrigerant, utilizing the physical processes of evaporation (absorbing heat) and condensation (releasing heat), thereby achieving a cooling or heating effect. With technological advancements, air conditioners not only possess cooling and heating functions but also integrate dehumidification, air purification, and other functions, becoming an indispensable appliance in modern life.

[0003] An air conditioner typically consists of major components such as a compressor, condenser, evaporator, expansion valve, and fan. The compressor drives the refrigerant circulation, the condenser and evaporator release and absorb heat respectively, the expansion valve regulates the refrigerant flow, and the fan accelerates airflow to enhance heat exchange efficiency.

[0004] In air conditioners with heating functions, when heating, the outdoor fan draws in cold air and produces a lot of condensation on the fan casing. Since there is nowhere to collect the condensation, it easily drips onto the ground, causing customer complaints. Some air conditioners use sponges attached to the fan casing to absorb water, but the absorption capacity is limited and it increases costs. Utility Model Content

[0044] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0045] Figure 1 This is a structural diagram of an air conditioner according to some embodiments of the present invention. Figure 2 yes Figure 1 A structural diagram from another perspective.

[0046] like Figure 1 and Figure 2 As shown in some embodiments of the present invention, the air conditioner may include a housing 1. The housing 1 may be configured as the outer casing of the air conditioner. The interior of the housing 1 may be used to provide installation space.

[0047] In some embodiments, the housing 1 may adopt a hollow cuboid structure. The length of the housing 1 may be arranged along the height direction, so that the air conditioner can be installed vertically in the usage site, thereby increasing the height of the air conditioner and reducing the space occupied by the air conditioner.

[0048] It should be noted that in other embodiments, the external shape of the housing 1 can be designed as needed, and no limitation is made here.

[0049] Figure 3 yes Figure 1 The structural diagram with the main shell 11 removed.

[0050] like Figure 1 and Figure 3 As shown, in some embodiments, the housing 1 may include a main housing 11. The main housing 11 may extend along the height direction. The height dimension of the main housing 11 may be greater than the left-right width dimension and the front-back width dimension of the main housing 11, so as to increase the height of the housing 1 and reduce the space occupied by the housing 1.

[0051] In some embodiments, the housing 1 may include a chassis 12. The chassis 12 may be disposed at the bottom of the main housing 11. A receiving space 10 may be formed between the top of the chassis 12 and the interior of the main housing 11. This receiving space 10 is used as a mounting space for other components of the air conditioner.

[0052] In some embodiments, the chassis 12 may be provided with feet 13 on its periphery. The feet 13 may extend outward from the chassis 12, and the feet 13 may be used to increase the contact area between the bottom of the housing 1 and the ground, thereby improving the reliability of the chassis 12 in supporting the air conditioner and improving the stability of the air conditioner.

[0053] In some embodiments, multiple feet 13 may be provided, and the multiple feet 13 may be connected end to end in sequence, so that the multiple feet 13 are arranged circumferentially around the periphery of the chassis 12. In this way, the multiple feet 13 can form a ring structure on the outer periphery of the chassis 12, which improves the structural strength between the multiple feet 13 and forms a complete ring structure; at the same time, it avoids the feet 13 from bumping into the user and improves the safety of using the air conditioner.

[0054] Figure 4 yes Figure 2 The structural diagram with the main shell 11 removed.

[0055] like Figure 3 and Figure 4As shown, in some embodiments, the air conditioner may include a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop may be located within 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. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, the outdoor heat exchanger 22, and the indoor heat exchanger 23. During the refrigerant circulation process, the outdoor heat exchanger 22 and the indoor heat exchanger 23 may serve as a condenser and an evaporator, respectively, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby executing either a cooling cycle or a heating cycle for the air conditioner.

[0056] Specifically, in the refrigeration cycle, the outdoor heat exchanger 22 can act as a condenser, and the indoor heat exchanger 23 can act as an evaporator. In the heating cycle, the outdoor heat exchanger 22 can act as an evaporator, and the indoor heat exchanger 23 can act as a condenser.

[0057] It should be noted that both the refrigeration and heating cycles involve a series of processes, including compression, condensation, expansion, and evaporation, and the supply of refrigerant to the conditioned and heat-exchanged air.

[0058] Compressor 21 is used to compress refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

[0059] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0060] The evaporator evaporates the expanded refrigerant and returns the refrigerant gas, now at a low temperature and low pressure, to the compressor 21. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the surrounding environment.

[0061] Throughout the cycle, the air conditioner can regulate the temperature of the indoor space, improve the comfort of the indoor space, and enhance the user experience.

[0062] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the air conditioner may include an outdoor fan assembly 3. The outdoor fan assembly 3 may be arranged opposite to the outdoor heat exchanger 22. The outdoor fan assembly 3 can be used to introduce outdoor air into the casing 1 for heat exchange with the outdoor heat exchanger 22, forming a heat exchange airflow.

[0063] For example, during the cooling cycle, the outdoor heat exchanger 22 acts as a condenser, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to dissipate heat and lower its temperature. During the heating cycle, the outdoor heat exchanger 22 acts as an evaporator, and the outdoor fan assembly 3 can draw in outside air and blow it onto the outdoor heat exchanger 22 to raise its temperature.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the air conditioner may include an indoor fan assembly 4. The indoor fan assembly 4 may be arranged opposite to the indoor heat exchanger 23. The indoor fan assembly 4 can be used to introduce indoor air into the housing 1 for heat exchange with the indoor heat exchanger 23, forming a heat exchange airflow.

[0065] For example, during the refrigeration cycle, the indoor heat exchanger 23 acts as an evaporator, and the indoor fan assembly 4 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, thereby reducing the temperature of the air flowing through the indoor heat exchanger 23 and blowing the cooled air back into the room to lower the indoor air temperature.

[0066] For example, during the heating cycle, the indoor heat exchanger 23 acts as a condenser, and the outdoor fan assembly 3 can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger 23 to exchange heat with it, raising the temperature of the air flowing through the indoor heat exchanger 23, and then blowing the heated air back into the room to raise the indoor air temperature.

[0067] like Figure 3 and Figure 4 As shown, in some embodiments, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be respectively arranged in the receiving space 10 inside the casing 1. In this way, the casing 1 can cover and protect them, preventing the erosion of foreign objects or the impact of external forces from causing structural damage, thereby improving the structural reliability of the air conditioner and ensuring that the air conditioner can work normally.

[0068] like Figure 3 and Figure 4As shown, in some embodiments, the internal accommodating space 10 of the casing 1 may include three sub-spaces. These three sub-spaces are, from bottom to top, a first sub-space 110, a second sub-space 120, and a third sub-space 130. The compressor 21 can be housed in the first sub-space 110. The outdoor heat exchanger 22 and the outdoor fan assembly 3 can be housed in the second sub-space 120. The indoor heat exchanger 23 and the indoor fan assembly 4 can be housed in the third sub-space 130. Thus, by using three layers of sub-spaces from bottom to top, the compressor 21, outdoor heat exchanger 22, outdoor fan assembly 3, indoor heat exchanger 23, and indoor fan assembly 4 can be distributed at different heights within the casing 1, which helps to increase the overall height of the air conditioner, reduce its width and thickness, and minimize the space occupied by the air conditioner in the operating area.

[0069] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, an indoor air inlet 111 may be provided on the outer wall of the housing 1. The indoor air inlet 111 may connect to the outside of the housing 1. The indoor air inlet 111 may connect to the indoor space. The indoor air inlet 111 may be located on the outer wall corresponding to the third subspace 130, and the indoor air inlet 111 may be arranged opposite to the air inlet end of the indoor heat exchanger 23 and the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is running, the indoor fan assembly 4 can draw indoor air into the housing 1 through the indoor air inlet 111 to exchange heat with the indoor heat exchanger 23, and the heat-exchanged air is discharged back into the indoor space outside the housing 1 through the air outlet end of the indoor fan assembly 4.

[0070] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, an indoor air outlet 112 may be provided on the outer wall of the housing 1. The indoor air outlet 112 may connect to the outside of the housing 1. The indoor air outlet 112 may connect to the indoor space. The indoor air outlet 112 may be located on the outer wall corresponding to the third subspace 130, and the indoor air outlet 112 may be arranged opposite to the air outlet end of the indoor fan assembly 4. In this way, when the indoor fan assembly 4 is running, the indoor fan assembly 4 draws indoor air through the indoor air inlet 111, exchanges heat with the indoor heat exchanger 23, and then discharges it back into the indoor space outside the housing 1 through the air outlet end and the indoor air outlet 112 of the indoor fan assembly 4.

[0071] like Figure 1 and Figure 3As shown, in some embodiments, an air guide plate 113 may be provided on the outer wall of the housing 1. The air guide plate 113 is rotatably disposed at the indoor air outlet 112. Multiple air guide plates 113 may be provided, and multiple air guide plates 113 may be arranged side by side at the indoor air outlet 112. When the air guide plate 113 rotates, the air guide plate 113 may open or close the indoor air outlet 112. When the air guide plate 113 rotates to open the indoor air outlet 112, the air guide plate 113 may also change the air outlet direction of the indoor air outlet 112.

[0072] like Figure 2 and Figure 4 As shown, in some embodiments, the air conditioner may include an air inlet duct 14. The air inlet duct 14 may be located in the space outside the casing 1. One end of the air inlet duct 14 may be connected to the air inlet end of the outdoor fan assembly 3. The other end of the air inlet duct 14 may be connected to the outdoor space. The air outlet end of the outdoor fan assembly 3 may be arranged towards the outdoor heat exchanger 22. In this way, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet duct 14, introduce outdoor air into the casing 1, and blow it towards the outdoor heat exchanger 22 to heat or cool the outdoor heat exchanger 22.

[0073] like Figure 2 and Figure 4 As shown, in some embodiments, the air conditioner may include an air outlet duct 15. The air outlet duct 15 may be located in the space outside the casing 1. One end of the air outlet duct 15 may communicate with the internal space of the casing 1. The other end of the air outlet duct 15 may communicate with the outdoor space. Thus, when the outdoor fan assembly 3 is running, the outdoor fan assembly 3 can draw air from the outdoor space through the air inlet duct 14, introduce outdoor air into the casing 1, and blow it towards the outdoor heat exchanger 22. The air flowing through the outdoor heat exchanger 22 inside the casing 1 is then discharged into the outdoor space through the air outlet duct 15, realizing outdoor air circulation.

[0074] like Figure 2 and Figure 4 As shown, in some embodiments, the air inlet duct 14 and the air outlet duct 15 can be located outside the third subspace 130. A receiving area 140 can be recessed on the upper part of the housing 1 corresponding to the outer wall of the third subspace 130. The air inlet duct 14 and the air outlet duct 15 can be arranged within the receiving area 140, so that the air inlet duct 14 and the air outlet duct 15 can be arranged above the second subspace 120, and so that the air inlet duct 14 and the air outlet duct 15 can be arranged above the outdoor heat exchanger 22 and the outdoor fan assembly 3.

[0075] In some embodiments, the air inlet duct 14 and the air outlet duct 15 can be arranged side-by-side in a receiving area 140 on the outer wall of the housing 1. The lower end of the air inlet duct 14 can communicate with the air inlet end of the outdoor fan assembly 3. The lower end of the air outlet duct 15 can communicate with the second subspace 120 inside the housing 1. The upper ends of the air inlet duct 14 and the upper ends of the air outlet duct 15 can connect to the outdoor space. During the installation of the air conditioner, the air inlet duct 14 and the air outlet duct 15 can be extended and fixed to a wall or window to connect to the outdoor space.

[0076] like Figure 3 and Figure 4 As shown, in some embodiments, the air conditioner may include a first drip tray 5. The first drip tray 5 may be disposed in the receiving space 10 within the casing 1. The first drip tray 5 may be arranged in the area between the first sub-space 110 and the second sub-space 120. The outdoor heat exchanger 22 may be disposed above the first drip tray 5. The first drip tray 5 may be used to collect condensate flowing down the outer wall of the outdoor heat exchanger 22. When the air conditioner is heating, the refrigerant can evaporate and absorb heat in the outdoor heat exchanger 22, lowering the surface temperature of the outdoor heat exchanger 22. Water vapor in the air condenses into water upon contact with the condensate, which then falls into the first drip tray 5 at the bottom of the outdoor heat exchanger 22, collected in the first drip tray 5, or discharged through the drain outlet on the first drip tray 5. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and the risk of people slipping.

[0077] In some embodiments, the bottom end of the air outlet duct 15 can be arranged in the space above the first water receiving tray 5. When outdoor rainwater enters the housing 1 through the air outlet duct 15, it can be collected by the first water receiving tray 5, preventing the rainwater from flowing directly to other areas inside the housing 1 or seeping out of the housing 1 and flowing to the ground.

[0078] Figure 5 yes Figure 4 A partial structural diagram.

[0079] like Figure 4 and Figure 5 As shown, in some embodiments, a first drain outlet 51 may be provided on the side wall of the first water receiving tray 5. A drain valve 52 may be provided at the first drain outlet 51. The drain valve 52 can block the first drain outlet 51. When the drain valve 52 opens the first drain outlet 51, the first drain outlet 51 can connect to the outside of the first water receiving tray 5, and the water in the first water receiving tray 5 can flow out of the outside of the first water receiving tray 5 through the first drain outlet 51.

[0080] like Figure 2 and Figure 4As shown, in some embodiments, the drain valve 52 can be located outside the housing 1, and the first drain port 51 can be connected to the outside of the housing 1. When the drain valve 52 opens the first drain port 51, the water in the first water receiving tray 5 can flow out to the outside of the housing 1 through the first drain port 51.

[0081] like Figure 3 and Figure 4 As shown, in some embodiments, the air conditioner may include a second drip tray 6. The second drip tray 6 may be disposed in the receiving space 10 within the housing 1. The second drip tray 6 may be arranged in the area between the second subspace 120 and the third subspace 130. The indoor heat exchanger 23 may be disposed above the second drip tray 6. The indoor fan assembly 4 may be disposed above the second drip tray 6. The second drip tray 6 may be used to collect condensate flowing down the outer wall of the indoor heat exchanger 23. When the air conditioner is cooling, the refrigerant can evaporate and absorb heat in the indoor heat exchanger 23, lowering the surface temperature of the indoor heat exchanger 23. Water vapor in the air condenses into water upon contact with the condensate, which then falls into the second drip tray 6 at the bottom of the indoor heat exchanger 23, collected in the second drip tray 6, or discharged through the drain outlet on the second drip tray 6. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and the risk of people slipping.

[0082] In some embodiments, a second drain outlet (not shown in the figure) may be provided on the bottom surface of the second water receiving tray 6. The second drain outlet is located above the outdoor heat exchanger 22 and the first water receiving tray 5. The condensate in the second water receiving tray 6 can flow through the second drain outlet to the outdoor heat exchanger 22, cooling the outdoor heat exchanger 22, and then flow down along the outer wall of the outdoor heat exchanger 22 into the first water receiving tray 5. In this way, the condensate in the second water receiving tray 6 can be discharged into the first water receiving tray 5 for collection, and heat exchange can be performed between the condensate and the outdoor heat exchanger 22 to cool the outdoor heat exchanger 22. For example, when the air conditioner is cooling, the outdoor heat exchanger 22, as a condenser, needs to dissipate heat to the outside, while the indoor heat exchanger 23, as an evaporator, needs to absorb heat to the outside. Air condenses into condensate on the surface of the indoor heat exchanger 23. The condensate can flow along the surface of the indoor heat exchanger 23 into the second water collection pan 6, and then through the second drain outlet of the second water collection pan 6 to the outer wall of the outdoor heat exchanger 22, dissipating heat and cooling the outdoor heat exchanger 22. Finally, it flows down the outer wall of the outdoor heat exchanger 22 into the first water collection pan 5 for collection.

[0083] like Figure 4 and Figure 5As shown, in some embodiments, the air conditioner may include a support member 7. The support member 7 may be disposed within the main housing 11. The support member 7 may be disposed within the receiving space 10. The support member 7 may be used to support the internal structure of the air conditioner. For example, the support member 7 may be used 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, etc., thereby increasing the structural strength and stability of the air conditioner's internal structure.

[0084] In some embodiments, the lower part of the support member 7 may be located within the first subspace 110, and the bottom end of the support member 7 may be fixed to the chassis 12. The upper part of the support member 7 may be located within the second subspace 120, and the top end of the support member 7 may be supported at the bottom of the second water receiving tray 6, facilitating the installation of the indoor heat exchanger 23 and the indoor fan assembly 4 on the second water receiving tray 6. This allows the indoor heat exchanger 23 and the indoor fan assembly 4 to be supported on the top end of the support member 7 via the second water receiving tray 6, thereby improving the structural stability of the indoor heat exchanger 23 and the indoor fan assembly 4 within the third subspace 130.

[0085] In some embodiments, the first water receiving tray 5 can be supported and fixed on the upper part of the support member 7, facilitating the installation of the outdoor heat exchanger 22 on the first water receiving tray 5 and its support and fixation on the support member 7 via the first water receiving tray 5. The outdoor fan assembly 3 can be located on the upper part of the support member 7. This facilitates the improvement of the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 within the second subspace 120.

[0086] It should be noted that in some other embodiments, the support member 7 can also be used to support any one or more of the outdoor heat exchanger 22, outdoor fan assembly 3, first water receiving tray 5, indoor heat exchanger 23, indoor fan assembly 4, and second water receiving tray 6. For example, the support member 7 can also be used to support the outdoor heat exchanger 22 and / or the indoor heat exchanger 23 alone.

[0087] Figure 6 yes Figure 5 A structural diagram from another perspective.

[0088] In some embodiments, the outdoor fan assembly 3 may include an outdoor duct housing 30. An outdoor duct may be formed inside the outdoor duct housing 30. The air inlet of the outdoor duct housing 30 may connect to the outside, and the air outlet of the outdoor duct housing 30 may face the outdoor heat exchanger 22. Specifically, the air inlet of the outdoor duct housing 30 may connect to an air inlet pipe 14, and through the air inlet pipe 14, connect to the outdoor space. The air outlet of the outdoor duct housing 30 may be arranged facing the outdoor heat exchanger 22. Thus, the duct inside the outdoor duct housing 30 can draw air from the outdoor space through the air inlet pipe 14, introduce outdoor air into the housing 1, and blow it towards the outdoor heat exchanger 22 to heat or cool the outdoor heat exchanger 22.

[0089] Figure 7 yes Figure 6 A schematic diagram of its decomposition.

[0090] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the outdoor duct housing 30 may include a volute member 31. The volute member 31 may be fixed to the support member 7. The duct within the outdoor duct housing 30 may be formed within the volute member 31.

[0091] It should be noted that in some other embodiments, the outdoor duct housing 30 may not use the volute 31, that is, it may not use the volute structure, and the outdoor duct housing 30 may use duct housings of other shapes.

[0092] like Figure 6 and Figure 7 As shown, in some embodiments, a volute portion 71 can be formed on the upper part of the support member 7. A volute member 31 can be fixed to the volute portion 71, thereby fixing the volute member 31 to the support member 7. The volute member 31 and the volute portion 71 can be joined to form a volute structure, within which an outdoor air duct can be formed. That is, the volute member 31 and the volute portion 71 can be joined to form a complete outdoor air duct housing 30. This volute structure has an air inlet end and an air outlet end. The air inlet end of the volute structure connects to the air inlet pipe 14, thereby connecting to the outdoor space. The air outlet end of the volute structure connects to the second subspace 120 and is arranged towards the outdoor heat exchanger 22.

[0093] It should be noted that in some other embodiments, the outdoor duct housing 30 can also be formed by joining two opposing volute components 31 together. The joined outdoor duct housing 30 can also be detachably fixed to the support member 7. Alternatively, the outdoor duct housing 30 can also be formed by a single complete volute component 31.

[0094] like Figure 6 and Figure 7 As shown, in some embodiments, the outdoor fan assembly 3 may include an outdoor impeller 33. The outdoor impeller 33 may be rotatably disposed within the outdoor duct housing 30, that is, the outdoor impeller 33 may be rotatably disposed within the outdoor duct. The outdoor impeller 33 may be rotatably disposed inside the volute component 31. When the outdoor impeller 33 rotates, wind power can be generated inside the volute structure, allowing air from the outdoor space to enter the volute structure through the air inlet pipe 14, that is, to enter the outdoor duct.

[0095] like Figure 6 and Figure 7As shown, in some embodiments, the outdoor fan assembly 3 may include an outdoor motor 32. The outdoor motor 32 may be mounted on the volute 31. The outdoor motor 32 may be fixed to the outside of the volute 31, so that the output shaft of the outdoor motor 32 extends into the inside of the volute 31 and is connected to the outdoor impeller 33 for transmission. In this way, the outdoor motor 32 can drive the outdoor impeller 33 to rotate inside the outdoor duct housing 30, thereby drawing air from the outdoor space into the outdoor duct housing 30 through the air inlet pipe 14 and blowing it into the second sub-space 120 to contact and exchange heat with the outdoor heat exchanger 22. The air after heat exchange can flow to the outside through the air outlet pipe 15. This solution integrates part of the outdoor duct housing 30 of the outdoor fan assembly 3 onto the support member 7, which can greatly improve the structural strength and structural stability of the outdoor fan assembly 3 and effectively ensure the stable operation of the outdoor fan assembly 3.

[0096] Figure 8 yes Figure 7 A schematic diagram of the structure of the volute component 31.

[0097] like Figure 7 and Figure 8 As shown, in some embodiments, a water-receiving portion 311 is provided on the outer wall of the outdoor duct housing 30. The water-receiving portion 311 may be provided on the outer wall of the volute member 31. The water-receiving portion 311 may be a groove-shaped structure. In the heating mode of the air conditioner, condensate forms on the outer wall of the outdoor duct housing 30, and the condensate can flow downward along the outer wall of the outdoor duct housing 30, flowing into the water-receiving portion 311. Specifically, condensate can form on the outer wall of the volute member 31, and the condensate can flow downward along the outer wall of the volute member 31 into the water-receiving portion 311.

[0098] Figure 9 yes Figure 8 The front view.

[0099] like Figure 7 and Figure 9As shown, in some embodiments, a guide hole 312 may be provided on the outer wall of the outdoor duct housing 30. The guide hole 312 may be provided on the outer wall of the volute member 31. The guide hole 312 may be arranged opposite to the water receiving part 311. The guide hole 312 may connect the water receiving part 311 and the interior of the outdoor duct housing 30. The guide hole 312 may connect the water receiving part 311 and the inner space of the volute member 31. Condensate on the outer wall of the outdoor duct housing 30 can flow downward into the water receiving part 311 and enter the interior of the outdoor duct housing 30 through the guide hole 312. Specifically, condensate can flow downward along the outer wall of the volute member 31 into the water receiving part 311, and then enter the interior of the volute member 31 through the guide hole 312. This allows condensate to drain easily from inside the outdoor duct housing 30, preventing condensate from dripping directly from the outer wall of the duct housing and splashing onto the ground, effectively increasing the condensate drainage performance of the outdoor fan assembly of the air conditioner.

[0100] Figure 10 yes Figure 8 A structural diagram from another perspective.

[0101] like Figure 7 and Figure 10 As shown, in some embodiments, a drain hole 34 may be provided on the inner bottom surface of the outdoor duct housing 30. Condensate from the outdoor duct housing 30 or condensate formed inside the outdoor duct housing 30 can flow along the inner wall to the bottom area inside the outdoor duct housing 30 and be discharged downwards through the drain hole 34. This facilitates the discharge of condensate from the drain hole 34 inside the outdoor duct housing 30, preventing condensate from dripping directly from the outer wall of the duct housing and splashing onto the ground, effectively increasing the condensate drainage performance of the outdoor fan assembly of the air conditioner.

[0102] It should be noted that in some other embodiments, rainwater entering the outdoor duct housing 30 through the air inlet pipe 14 can also flow along the inner wall to the bottom area inside the outdoor duct housing 30 and be discharged downward through the drain hole 34.

[0103] like Figure 7 and Figure 10 As shown, in some embodiments, multiple drainage holes 34 may be provided. Multiple drainage holes 34 may be arranged at intervals on the inner bottom surface of the outdoor air duct housing 30.

[0104] like Figure 7 As shown, in some embodiments, the plurality of drain holes 34 may include a first drain hole 341. The first drain hole 341 may be provided at the bottom of the volute portion 71. In this way, condensate or rainwater in the outdoor duct housing 30 can flow down along the inner wall to the first drain hole 341 and be discharged downward through the first drain hole 341.

[0105] like Figure 10As shown, in some embodiments, the plurality of drainage holes 34 may include a second drainage hole 342. The second drainage hole 342 may be located at the bottom of the volute member 31. The second drainage hole 342 may be located at the side edge of the volute member 31 near the volute portion 71. When the volute member 31 and the volute portion 71 are joined to form the outdoor air duct housing 30, the second drainage hole 342 may be located at the joint between the volute member 31 and the volute portion 71. In this way, condensate or rainwater inside the outdoor air duct housing 30 can flow downwards along the joint between the volute member 31 and the volute portion 71 to the second drainage hole 342, and then be discharged downwards through the second drainage hole 342, improving the discharge efficiency of condensate or rainwater.

[0106] It should be noted that in some other embodiments, the plurality of drainage holes 34 may also include a third drainage hole or a fourth drainage hole. The position of the third drainage hole or the fourth drainage hole can be adjusted as needed, and is not limited here.

[0107] like Figure 8 and Figure 9 As shown, in some embodiments, a first water-blocking rib 313 may be provided on the outer periphery of the outer side wall of the volute 31. The first water-blocking rib 313 may be located on the outer periphery of the outer side wall of the outdoor air duct housing 30. The water receiving part 311 and the guide hole 312 may be located on the inner side of the first water-blocking rib 313. In this way, condensate on the outer side wall of the volute 31 can flow downward along the outer side wall of the volute 31, and the flow direction of the condensate is restricted by the first water-blocking rib 313, guiding the condensate to the water receiving part 311, and then entering the interior of the volute 31 through the guide hole 312.

[0108] In some embodiments, the water receiving portion 311 and the guide hole 312 may be provided in the bottom region of the outer wall of the volute 31. The water receiving portion 311 may be provided in the bottom region inside the first water-blocking rib 313. In this way, condensate on the outer wall of the volute 31 can flow downward along the outer wall of the volute 31 to the bottom region inside the first water-blocking rib 313, thereby smoothly collecting the condensate at the water receiving portion 311, and then entering the interior of the volute 31 through the guide hole 312.

[0109] like Figure 8 and Figure 9As shown, in some embodiments, a flange 3131 may be provided on the outer side wall of the volute 31. The flange 3131 may be provided in the bottom region of the first water-blocking rib 313. The flange 3131 may extend upward from the bottom region of the first water-blocking rib 313. The flange 3131 may be provided at intervals on the outside of the drain hole 34. The water receiving part 311 may be formed between the first water-blocking rib 313, the flange 3131 and the outer side wall of the volute 31. In this way, when the condensate on the outer side wall of the volute 31 flows downward along the outer side wall of the volute 31, the flow direction of the condensate is restricted by the first water-blocking rib 313, and the trough-shaped structure between the first water-blocking rib 313, the flange 3131 and the outer side wall of the volute 31, and the condensate can be guided to the water receiving part 311, and then collected at the water receiving part 311, so that the condensate in the water receiving part 311 can enter the interior of the volute 31 through the guide hole 312.

[0110] like Figure 8 and Figure 9 As shown, in some embodiments, the outer wall of the volute 31 may be provided with a second water-blocking rib 314. The second water-blocking rib 314 may be annular and arranged around the outer periphery of the outdoor motor 32. The second water-blocking rib 314 may be located inside the first water-blocking rib 313. The second water-blocking rib 314 and the first water-blocking rib 313 may be arranged with an inner and outer gap. The first water-blocking rib 313 may be arranged around the outer periphery of the second water-blocking rib 314. The water receiving part 311 and the guide hole 312 may be provided in the bottom region of the space between the first water-blocking rib 313 and the second water-blocking rib 314. Thus, a water collection channel can be formed in the space between the first water-blocking rib 313 and the second water-blocking rib 314. By cooperating with the first water-blocking rib 313, the condensate on the outer wall of the volute 31 can be confined in the water collection channel between the second water-blocking rib 314 and the first water-blocking rib 313, and then flow smoothly to the bottom area of ​​the water collection channel and into the water receiving part 311, so that the condensate can smoothly enter the interior of the volute 31 through the guide hole 312.

[0111] like Figure 7 and Figure 9 As shown, in some embodiments, a mounting port 315 may be provided on the outer wall of the volute 31. The outdoor motor 32 may be located at the mounting port 315. The second water-blocking rib 314 may be arranged around the outer periphery of the mounting port 315. In this way, condensate on the outer wall of the volute 31 can be prevented from overflowing the second water-blocking rib 314, and condensate can be prevented from contacting the outdoor motor 32 through the mounting port 315, thus ensuring the safe and stable operation of the outdoor motor 32.

[0112] like Figure 8 and Figure 9As shown, in some embodiments, the outer wall of the volute 31 may be provided with a first water-guiding rib 3132. The first water-guiding rib 3132 may be provided in the interval area between the first water-blocking rib 313 and the second water-blocking rib 314. That is, the first water-guiding rib 3132 may be provided in the water collection channel. The first water-guiding rib 3132 may be arranged extending from the first water-blocking rib 313 toward the second water-blocking rib 314. There is a gap between the first water-guiding rib 3132 and the second water-blocking rib 314. In this way, the condensate on the upper side of the first water-guiding rib 3132 can flow along the direction from the first water-guiding rib 3132 toward the second water-blocking rib 314, and flow downward through the gap between the first water-guiding rib 3132 and the second water-blocking rib 314, so that the condensate can quickly flow toward the bottom area of ​​the interval area between the first water-blocking rib 313 and the second water-blocking rib 314, and smoothly collect in the water receiving part 311.

[0113] In some embodiments, a plurality of first water-guiding ribs 3132 may be provided in the spaced area between the first water-blocking rib 313 and the second water-blocking rib 314. The plurality of first water-guiding ribs 3132 may be arranged circumferentially. The cooperation of the plurality of first water-guiding ribs 3132 can improve the flow efficiency of condensate water, so that the condensate water can be smoothly collected in the water receiving part 311.

[0114] like Figure 8 and Figure 9 As shown, the outer wall of the volute 31 may be provided with a second water-guiding rib 3141. The second water-guiding rib 3141 may be provided in the interval area between the first water-blocking rib 313 and the second water-blocking rib 314. That is, the second water-guiding rib 3141 may be provided in the water collection channel. The second water-guiding rib 3141 may extend from the second water-blocking rib 314 toward the first water-blocking rib 313. There may be a gap between the second water-guiding rib 3141 and the first water-blocking rib 313. In this way, the condensate on the upper side of the second water-guiding rib 3141 may flow along the second water-guiding rib 3141 toward the first water-blocking rib 313, and flow downward through the gap between the second water-guiding rib 3141 and the first water-blocking rib 313, so that the condensate can quickly flow toward the bottom area of ​​the interval area between the first water-blocking rib 313 and the second water-blocking rib 314, and smoothly collect in the water receiving part 311.

[0115] In some embodiments, a plurality of spaced-apart second water-guiding ribs 3141 may be provided in the spaced area between the first water-blocking rib 313 and the second water-blocking rib 314. The plurality of second water-guiding ribs 3141 may be arranged circumferentially. The cooperation of the plurality of second water-guiding ribs 3141 can improve the flow efficiency of condensate water, so that the condensate water can be smoothly collected in the water receiving part 311.

[0116] In some embodiments, the first water-blocking rib 313 may protrude from the outer wall of the volute 31 by a height greater than 3 mm. The second water-blocking rib 314 may protrude from the outer wall of the volute 31 by a height greater than 3 mm. This prevents condensate from overflowing in the area between the first water-blocking rib 313 and the second water-blocking rib 314.

[0117] like Figure 3 and Figure 4 As shown, in some embodiments, a fixing rod 114 may be provided inside the housing 1. The fixing rod 114 may be located inside the main housing 11. The fixing rod 114 may extend vertically. One side of the outdoor fan assembly 3 may be fixed to the fixing rod 114. One side of the first water receiving tray 5 may be fixed to the fixing rod 114. One side of the indoor fan assembly 4 may be fixed to the fixing rod 114. One side of the second water receiving tray 6 may be fixed to the fixing rod 114. In this way, the structural strength and structural stability of multiple components inside the housing 1 can be improved by using the fixing rod 114.

[0118] In some embodiments, the housing 1 may contain two fixing rods 114. The two fixing rods 114 may be located on opposite sides within the main housing 11. The outdoor fan assembly 3, the first water receiving tray 5, the indoor fan assembly 4, and the second water receiving tray 6 may be fixed to either of the two fixing rods 114.

[0119] like Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, a fixing part 316 may be provided on the outer wall of the volute 31. The fixing part 316 may be arranged vertically at the center of the outer wall of the volute 31. The fixing part 316 may be fixedly connected to the fixing rod 114. Two water receiving parts 311 may be provided on the outer wall of the volute 31. The two water receiving parts 311 may be respectively provided on opposite sides of the fixing part 316. Both water receiving parts 311 are provided on the inner side of the first water-blocking rib 313. Two flow guiding holes 312 may be provided on the outer wall of the volute 31. The two flow guiding holes 312 may be arranged corresponding to the two water receiving parts 311 respectively. In addition, two flanged parts 3131 may also be provided. The two flanged parts 3131 may be arranged corresponding to the two flow guiding holes 312 respectively, thereby forming a water receiving part 311 on each of the two flanged parts 3131.

[0120] It should be noted that in some other embodiments, the number of water receiving parts 311 and guide holes 312 can be adjusted as needed, and no limitation is made here.

[0121] Figure 11 yes Figure 6 A schematic diagram of the structure of the central control box 8. Figure 12 yes Figure 6 A structural diagram from another perspective.

[0122] like Figure 6 , Figure 11 and Figure 12 As shown, in some embodiments, the air conditioner may include an electrical control box 8. The electrical control box 8 may be located inside the housing 1. The electrical control box 8 may be located within the receiving space 10. The electrical control box 8 may be electrically connected to the compressor 21, the outdoor fan assembly 3, and the indoor fan assembly 4, respectively. Thus, the electrical control box 8 can control the on / off state of the circuits of the compressor 21, the outdoor fan assembly 3, and the indoor fan assembly 4, thereby controlling the normal operation of the air conditioner.

[0123] like Figure 4 and Figure 12 As shown, in some embodiments, the control box 8 may be located within the first subspace 110. The control box 8 may be located above the chassis 12. The control box 8 may be located on one side of the support member 7. The control box 8 may be located below the volute member 31.

[0124] like Figure 6 , Figure 11 and Figure 12 As shown, in some embodiments, the air conditioner may include a reactor assembly 9. The reactor assembly 9 may include a reactor. The reactor assembly 9 may be disposed within a receiving space 10 inside the housing 1. The reactor assembly 9 may be disposed within a first subspace 110. The reactor assembly 9 may be disposed on one side of the electrical control box 8. The reactor assembly 9 may be disposed above the chassis 12. The reactor may be electrically connected to components such as the main control board within the electrical control box 8. The reactor may perform functions such as filtering, stabilizing current and voltage, improving power factor, or suppressing surge current.

[0125] Figure 13 yes Figure 7 A schematic diagram of the structure of the mid-chassis 12 and the support component 7. Figure 14 yes Figure 13 A structural diagram from another perspective.

[0126] like Figure 13 and Figure 14 As shown, in some embodiments, the lower part of the support member 7 may include a support plate 72. The support plate 72 may be arranged laterally within the first subspace 110. The upper end of the support plate 72 may be integrally connected to the lower end of the volute portion 71. The lower end of the support plate 72 may be supported and fixed on the chassis 12. The lateral width of the support plate 72 may be substantially the same as the lateral width of the volute portion 71, so that the volute portion 71 can be supported on the chassis 12 by the support plate 72, further improving the structural strength and structural stability of the outdoor fan assembly 3.

[0127] It should be noted that in some other embodiments, the upper and lower parts of the support member 7 can also be separate structures, that is, the volute 71 and the support plate 72 can also be separate structures. The volute 71 can be detachably fixed to the upper end of the support plate 72.

[0128] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the lower part of the support member 7 may include a first support wall 73 and a second support wall 74. The first support wall 73 may extend from one lateral end of the support plate 72 toward one side of the support plate 72. The second support wall 74 may extend from the other lateral end of the support plate 72 toward the same side of the support plate 72. The lower ends of the first support wall 73 and the second support wall 74 may be supported and fixed on the chassis 12. The first water receiving tray 5 may be simultaneously supported and fixed on the support plate 72, the first support wall 73, and the second support wall 74, thereby improving the support reliability of the first water receiving tray 5 and improving the structural stability of the first water receiving tray 5. In addition, the support plate 72, the first support wall 73, and the second support wall 74 may form a frame-like three-sided structure, which can effectively improve the structural strength of the lower part of the support member 7 and further improve the structural strength and structural stability inside the air conditioner.

[0129] Figure 15 yes Figure 14 A structural diagram from another perspective. Figure 16 yes Figure 15 A schematic diagram of the structure of the middle chassis 12.

[0130] like Figure 15 and Figure 16 As shown, in some embodiments, a support portion 121 may be provided on the top surface of the chassis 12. The bottom end of the support member 7 may be supported on the support portion 121. The support plate 72, the first support wall 73, and the second support wall 74 at the lower part of the support member 7 may be supported on the support portion 121 respectively, thereby improving the support stability of the lower part of the support member 7.

[0131] like Figure 14 and Figure 16As shown, in some embodiments, the support portion 121 may include a first support rib 1211 and a second support rib 1212 arranged at intervals. The first support rib 1211 may protrude from the top surface of the chassis 12. The second support rib 1212 may protrude from the top surface of the chassis 12 and be arranged at intervals relative to the first support rib 1211. A support groove 1213 may be formed between the first support rib 1211 and the second support rib 1212. The bottom end of the support member 7 may be inserted into the support groove 1213, and the opposite side walls of the bottom end of the support member 7 may be supported on the first support rib 1211 and the second support rib 1212 respectively, thereby improving the structural strength and structural stability of the connection between the bottom end of the support member 7 and the chassis 12, and enhancing the reliability of the support portion 121 in supporting the support member 7.

[0132] Specifically, the lower end of the support plate 72 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the support plate 72 are respectively supported on the first support rib 1211 and the second support rib 1212; the lower end of the first support wall 73 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the first support wall 73 are respectively supported on the first support rib 1211 and the second support rib 1212; the lower end of the second support wall 74 can be inserted and fixed in the support groove 1213, and the opposite side walls of the lower end of the second support wall 74 are respectively supported on the first support rib 1211 and the second support rib 1212.

[0133] like Figure 7 , Figure 14 and Figure 16 As shown, in some embodiments, a water collection trough may be provided on the top surface of the chassis 12. The water collection trough can be used to collect and collect rainwater or condensate inside the housing 1. Water discharged downward from the drain hole 34 on the outdoor air duct housing 30 can flow downward along the side wall of the support member 7 into the water collection trough, which facilitates the collection of rainwater or condensate in the water collection trough and prevents it from overflowing directly onto the bottom surface of the housing 1.

[0134] In some embodiments, multiple water collection tanks may be provided, including a first water collection tank 124 and a second water collection tank 125. The first water collection tank 124 may be located on one side of the support portion 121. The second water collection tank 125 may be located on the other side of the support portion 121. The first water collection tank 124 and the second water collection tank 125 may be located on opposite sides of the support portion 121. Both the first water collection tank 124 and the second water collection tank 125 can be used to collect and receive rainwater or condensate from inside the casing 1. The cooperation of the first water collection tank 124 and the second water collection tank 125 can effectively increase the water storage space of the chassis 12. Under the premise that the support member 7 needs to be supported on the chassis 12, the structural arrangement of the first water collection tank 124 and the second water collection tank 125 can effectively improve the space utilization efficiency of the chassis 12, thereby reasonably expanding the water storage space of the chassis 12.

[0135] It should be noted that in some other embodiments, the multiple water collection tanks may include a third water collection tank or a fourth water collection tank, etc. The number and position of the water collection tanks other than the first water collection tank 124 and the second water collection tank 125 can be adjusted as needed, and are not limited here.

[0136] like Figure 7 , Figure 14 and Figure 16 As shown, in some embodiments, the chassis 12 may be provided with a connecting channel 122 penetrating the support portion 121. One end of the connecting channel 122 may be connected to the first water collection tank 124. The other end of the connecting channel 122 may be connected to the second water collection tank 125. The connecting channel 122 connects the first water collection tank 124 and the second water collection tank 125, allowing rainwater or condensate in the first water collection tank 124 to enter the second water collection tank 125 through the connecting channel 122, and rainwater or condensate in the second water collection tank 125 to enter the first water collection tank 124 through the connecting channel 122. This fully utilizes the water storage space of the first water collection tank 124 and the second water collection tank 125, improving the storage effect of rainwater or condensate, thereby effectively enhancing and efficiently utilizing the water storage space of the chassis 12.

[0137] In some embodiments, the first water collection tank 124 may be located on the side of the first support rib 1211 away from the second support rib 1212. The second water collection tank 125 may be located on the side of the second support rib 1212 away from the first support rib 1211. The connecting channel 122 may be arranged to pass through the first support rib 1211, the support groove 1213, and the second support rib 1212 in sequence. Furthermore, the connecting channel 122 may be isolated from the support groove 1213, i.e., the connecting channel 122 may be isolated from the support groove 1213. Thus, while the connecting channel 122 connects the first water collection tank 124 and the second water collection tank 125, water in the first water collection tank 124 and the second water collection tank 125 may be prevented from entering the support groove 1213, and water residue in the support groove 1213 may be avoided.

[0138] like Figure 16As shown, in some embodiments, a step 126 may be provided inside the second water collection tank 125. A drain outlet 1261 may be provided on the top surface of the step 126. This drain outlet 1261 can connect to the space below the bottom of the chassis 12. Thus, when the water level in the second water collection tank 125 is higher than the top of the drain outlet 1261, excess condensate or rainwater in the second water collection tank 125 can be discharged to the outside of the casing 1 through the drain outlet 1261; excess condensate or rainwater in the first water collection tank 124 can first enter the second water collection tank 125, and then be discharged to the outside of the casing 1 through the drain outlet 1261. When there is a large amount of rainwater or condensate, and the first and second water collection tanks 124 cannot hold more water, excess water on the chassis 12 can be drained through the drain outlet 1261, preventing excessive accumulation of rainwater or condensate inside the casing 1.

[0139] In some other embodiments, the step portion 126 and the outlet 1261 may also be provided in the first water collection tank 124. Alternatively, multiple steps 126 and outlets 1261 may be provided, with multiple steps 126 and corresponding outlets 1261 respectively provided in the first water collection tank 124 and the second water collection tank 125.

[0140] like Figure 7 , Figure 13 and Figure 15 As shown, in some embodiments, the first drain hole 341 inside the outdoor duct housing 30 discharges condensate or rainwater, which can flow downwards through the outer wall of the support member 7 onto the chassis 12 and be collected in the water collection tank of the chassis 12. In this way, rainwater or condensate can be effectively prevented from accumulating inside the outdoor duct housing 30, ensuring the stable operation of the outdoor fan assembly 3.

[0141] In some embodiments, the sidewall of the support member 7 may be provided with a vertically extending drainage channel 75. The lower end of the drainage channel 75 is disposed above the water collection tank. The drainage channel 75 is disposed below the drain hole 34. For example, the lower end of the drainage channel 75 is disposed above the first water collection tank 124 or above the second water collection tank 125. In this way, water discharged downward from the drain hole 34 can flow into the drainage channel 75 and flow into the water collection tank along the drainage channel 75.

[0142] In some embodiments, the sidewall of the support member 7 may be provided with a first drainage rib 721 and a second drainage rib 722 extending vertically. The first drainage rib 721 and the second drainage rib 722 may be arranged opposite each other with a left-right interval. A drainage channel 75 may be formed in the region between the first drainage rib 721 and the second drainage rib 722. In this way, water discharged downward from the drain hole 34 can flow into the region between the first drainage rib 721 and the second drainage rib 722, and flow downward along the region between the first drainage rib 721 and the second drainage rib 722 into the water collection tank of the chassis 12.

[0143] In some embodiments, the support member 7 may be provided with a guide rib 723 on its side wall. The guide rib 723 may be located above the first guide rib 721. The guide rib 723 may be located below the volute portion 71. The upper end of the guide rib 723 may extend below the first drain hole 341. The guide rib 723 may be located on the side of the upper end of the first guide rib 721 away from the second guide rib 722. The lower end of the guide rib 723 may extend to the upper end of the first guide rib 721. The lower end of the guide rib 723 may extend to the drainage channel 75. In this way, the condensate or rainwater discharged from the first drain hole 341 in the outdoor air duct housing 30 can flow through the guide rib 723 to the first guide rib 721, and then flow into the drainage channel 75, and flow downwards into the water collection tank along the drainage channel 75.

[0144] It should be noted that in some other embodiments, the guide rib 723 may also be located above the second guide rib 722. The guide rib 723 may be located on the side of the upper end of the second guide rib 722 away from the first guide rib 721. The lower end of the guide rib 723 may extend to the upper end of the second guide rib 722, so that the lower end of the guide rib 723 may extend to the drainage channel 75. In this way, the condensate or rainwater discharged from the first drain hole 341 can flow through the guide rib 723 to the second guide rib 722, and then flow into the drainage channel 75, and flow downwards into the water collection tank along the drainage channel 75.

[0145] like Figure 7 , Figure 13 and Figure 15 As shown, in some embodiments, the second drain hole 342 inside the outdoor duct housing 30 discharges condensate or rainwater, which can flow downwards through the outer wall of the support member 7 onto the chassis 12 and be collected in the water collection tank of the chassis 12. In this way, rainwater or condensate can be effectively prevented from accumulating inside the outdoor duct housing 30, ensuring the stable operation of the outdoor fan assembly 3.

[0146] like Figure 12 , Figure 13 and Figure 15As shown, in some embodiments, a receiving groove 76 may be provided on the side wall of the support member 7. The receiving groove 76 may be arranged in the lower region of the volute member 31. The receiving groove 76 and the drainage channel 75 may be arranged on opposite side walls of the support member 7. A water inlet hole 724 may be provided on the side wall of the support member 7. The water inlet hole 724 may connect the receiving groove 76 and the drainage channel 75. In this way, condensate or rainwater discharged downward from the drain hole 34 can flow downward into the receiving groove 76, flow into the drainage channel 75 through the water inlet hole 724, and then flow downward into the water collection tank along the drainage channel 75. Specifically, the receiving groove 76 may be arranged below the second drain hole 342. Condensate or rainwater discharged from the second drain hole 342 in the outdoor air duct housing 30 can flow downward into the receiving groove 76, flow into the drainage channel 75 through the water inlet hole 724, and then flow downward into the water collection tank along the drainage channel 75.

[0147] In some embodiments, the water inlet 724 may be arranged in the upper region of the drainage channel 75. In this way, water in the receiving tank 76 can flow through the water inlet 724 to the upper region of the drainage channel 75, flow downward through the water inlet 724 into the drainage channel 75, and then flow downward along the drainage channel 75 into the water collection tank.

[0148] like Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, the top surface of the electrical control box 8 may be recessed with a guide groove 81. The guide groove 81 is located above one side of the receiving groove 76. The guide groove 81 may be arranged at an angle. The guide groove 81 may extend at an angle toward one side of the receiving groove 76. The guide groove 81 may be arranged in the lower region of the volute 31. The guide groove 81 may be arranged below the drain hole 34. In this way, the condensate or rainwater discharged downward from the drain hole 34 can first fall into the guide groove 81, and flow along the guide groove 81 into the receiving groove 76, flow into the drainage channel 75 through the water inlet hole 724, and then flow downward along the drainage channel 75 into the water collection tank. Specifically, the guide channel 81 can be arranged below the second drain hole 342. The condensate or rainwater discharged from the second drain hole 342 in the outdoor air duct housing 30 can first fall into the guide channel 81 and flow along the guide channel 81 to the receiving groove 76, flow into the diversion channel 75 through the water inlet hole 724, and then flow down into the water collection tank along the diversion channel 75.

[0149] It should be noted that some of the condensate on the outer wall of the volute 31 can also drip onto the guide groove 81 through its bottom area, flow along the guide groove 81 into the receiving groove 76, flow into the guide channel 75 through the water inlet hole 724, and then flow down into the water collection tank along the guide channel 75.

[0150] like Figure 11 and Figure 12As shown, in some embodiments, a guide outlet 82 may be provided on the top side of the electrical control box 8 facing the receiving groove 76. The guide outlet 82 may be located at the bottom of the guide groove 81. The guide outlet 82 may be arranged above the receiving groove 76. In this way, condensate or rainwater falling into the guide groove 81 can flow along the guide groove 81 to the guide outlet 82, and then flow into the receiving groove 76 through the guide outlet 82, preventing condensate or rainwater from flowing down the outer wall of the electrical control box 8, thereby preventing condensate or rainwater from entering the electrical control box 8, avoiding safety problems such as short circuits of electrical components in the electrical control box 8, and effectively improving the safety and reliability of the air conditioner operation.

[0151] like Figure 12 and Figure 13 As shown, in some embodiments, a guide wall 725 may be provided on the side wall of the support member 7. The guide wall 725 may be provided above the receiving groove 76. The guide wall 725 may be provided below the volute portion 71 and the volute member 31. The guide wall 725 may be arranged inclined towards the guide groove 81. The lower end of the guide wall 725 may be arranged above the guide groove 81. In this way, some of the condensate on the outer wall of the volute portion 71 and the volute member 31 may also flow downward along the guide wall 725, flow into the guide groove 81, then flow along the guide groove 81 into the receiving groove 76, flow into the guide channel 75 through the water inlet hole 724, and then flow downward along the guide channel 75 into the water collection tank.
