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, fan, and chassis. 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. The chassis, as the basic structure of the air conditioner, not only supports these components but also provides fixation and support.

[0004] In related air conditioners, the chassis also serves to collect and drain condensate or rainwater to ensure normal operation. However, the design of these air conditioner chassis has certain flaws, particularly regarding the water storage space. Due to structural limitations, the water storage space is typically small or lacks a dedicated storage area, leading to problems such as poor drainage or overflow during rainy weather.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] Figure 3 yes Figure 1 The structural diagram with the main shell 11 removed.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Figure 4 yes Figure 2 The structural diagram with the main shell 11 removed.

[0051] like Figure 3 and Figure 4 As 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.

[0052] 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.

[0053] 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.

[0054] Compressor 21 is used to compress refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

[0055] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] like Figure 3 and Figure 4 As 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.

[0065] 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.

[0066] 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 of the indoor fan assembly and the indoor air outlet 112.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] like Figure 4 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.

[0075] like Figure 2 and Figure 4 As 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.

[0076] like Figure 3 and Figure 4As 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.

[0077] 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.

[0078] Figure 5 yes Figure 4 Partial structural diagram of the middle part.

[0079] like Figure 4 and Figure 5 As 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] like Figure 4 and Figure 5 As shown, in some embodiments, the outdoor fan assembly 3 may include a volute 31. A volute portion 71 may be formed on the upper part of the support member 7. The volute 31 may be fixed to the volute portion 71, and the volute 31 and the volute portion 71 may be joined to form a complete volute structure. An outdoor air duct is formed within the volute structure. 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, and thus connects 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.

[0084] In some embodiments, the outdoor fan assembly 3 may include an outdoor impeller (not shown in the figure). The outdoor impeller may be rotatably disposed inside the volute structure. That is, the outdoor impeller may be rotatably disposed inside the outdoor air duct. When the outdoor impeller rotates, wind force can be generated inside the volute structure, allowing air from the outdoor space to enter the volute structure through the air inlet pipe 14, i.e., into the outdoor air duct.

[0085] In some embodiments, the outdoor fan assembly 3 may include an outdoor motor 32. The outdoor motor 32 can be fixed to the outside of the volute 31, with the output shaft of the outdoor motor 32 extending into the volute structure and drivingly connected to the outdoor impeller. Thus, the outdoor motor 32 can drive the outdoor impeller to rotate inside the volute structure, thereby drawing outdoor air into the volute structure through the inlet pipe 14 and blowing it into the second sub-space 120 to contact and exchange heat with the outdoor heat exchanger 22. The heat-exchanged air can then flow to the outside through the outlet pipe 15. This solution integrates part of the volute structure of the outdoor fan assembly 3 onto the support member 7, which can greatly improve the structural strength and stability of the outdoor fan assembly 3, effectively ensuring the stable operation of the outdoor fan assembly 3.

[0086] like Figure 4 and Figure 5 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.

[0087] 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.

[0097] In some embodiments, the support groove 1213 may include a second groove portion 12132. The second groove portion 12132 may extend from one end of the first groove portion 12131 along its length toward one side of the first groove portion 12131. The bottom end of the support member 7 may be inserted into the second groove portion 12132. The lower end of the first support wall 73 may be inserted and fixed into the second groove portion 12132, thereby improving the structural strength and connection stability of the lower end of the first support wall 73 and the entire bottom end of the support member 7.

[0098] In some embodiments, the support groove 1213 may include a third groove portion 12133. The third groove portion 12133 may extend from the other end of the first groove portion 12131 along the same side as the first groove portion 12131. The bottom end of the support member 7 may be inserted into the third groove portion 12133. The lower end of the second support wall 74 may be inserted and fixed into the third groove portion 12133, thereby improving the structural strength and connection stability of the lower end of the second support wall 74 and the entire bottom end of the support member 7.

[0099] like Figure 6 , Figure 8 and Figure 10 As shown, in some embodiments, a first water collection tank 124 may be provided on the top surface of the chassis 12. The first water collection tank 124 may be provided on one side of the support portion 121. The first water collection tank 124 may be used to collect and collect rainwater or condensate from inside the casing 1.

[0100] like Figure 6 , Figure 8 and Figure 10 As shown, in some embodiments, a second water collection tank 125 may be provided on the top surface of the chassis 12. 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. The second water collection tank 125 may also 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.

[0101] In some embodiments, the first groove 12131 may be arranged laterally between the first water collection tank 124 and the second water collection tank 125. The second groove 12132 may extend from one end of the first groove 12131 toward one side of the first water collection tank 124. The third groove 12133 may extend from the other end of the first groove 12131 toward one side of the first water collection tank 124. In this way, the second groove 12132 and the third groove 12133 can be arranged on the same side of the first groove 12131, which facilitates the bottom of the support member 7 to be fixed to the first groove 12131, the second groove 12132 and the third groove 12133 respectively, forming a frame-type three-sided fixing structure, effectively improving the structural strength and connection stability of the bottom of the entire support member 7.

[0102] like Figure 6 , Figure 8 and Figure 10 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.

[0103] Figure 11 yes Figure 10 Sectional view along line AA. Figure 12 yes Figure 10 Sectional view along the BB direction.

[0104] like Figure 6 , Figure 11 and Figure 12 As shown, 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.

One or more first partition plates 1242 facilitate the division of the first water collection tank 124 into multiple first water collection units 1241, making it easier to collect rainwater or condensate in each of the multiple first water collection units 1241.

[0107] like Figure 8 and Figure 9As shown, in some embodiments, a first overflow port 1243 may be provided on the first partition plate 1242. The first overflow port 1243 can be connected to the first water collection units 1241 on both sides of the first partition plate 1242. In this way, adjacent first water collection units 1241 can be interconnected through the first overflow port 1243. When the water level of rainwater or condensate in one of the first water collection units 1241 is higher than the first overflow port 1243, it can flow through the first overflow port 1243 to the adjacent first water collection unit 1241, thereby making full use of the water storage space of each first water collection unit 1241.

[0108] In some embodiments, the first overflow port 1243 may be located at the top edge of the first partition plate 1242. Alternatively, the first overflow port 1243 may be located at the bottom edge of the first partition plate 1242. Alternatively, the first overflow port 1243 may be located at other positions on the first partition plate 1242.

[0109] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the second water collection tank 125 may include a plurality of second water collection units 1251. The plurality of second water collection units 1251 are all disposed on the same side of the support portion 121, that is, the plurality of second water collection units 1251 are all disposed on the side of the support portion 121 away from the first water collection tank 124. The other end of the connecting channel 122 may communicate with one of the second water collection units 1251, thereby facilitating the connection of the remaining plurality of second water collection units 1251 through that second water collection unit 1251.

[0110] In some embodiments, a second partition plate 1252 may be provided within the second water collection tank 125, which can divide the second water collection tank 125 into a plurality of second water collection units 1251. Multiple second partition plates 1252 may be provided, and each of the multiple second partition plates 1252 may be located between different adjacent second water collection units 1251. One or more second partition plates 1252 facilitate the division of the second water collection tank 125 into multiple second water collection units 1251, making it easier to collect rainwater or condensate in each of the individual second water collection units 1251.

[0111] like Figure 8 and Figure 9As shown, in some embodiments, a second overflow port 1253 may be provided on the second partition plate 1252. The second overflow port 1253 can be connected to the second water collection units 1251 on both sides of the second partition plate 1252. In this way, adjacent second water collection units 1251 can be interconnected through the second overflow port 1253. When the water level of rainwater or condensate in one of the second water collection units 1251 is higher than the first overflow port 1243, it can flow through the second overflow port 1253 to the adjacent second water collection unit 1251, thereby making full use of the water storage space of each second water collection unit 1251.

[0112] In some embodiments, the second overflow port 1253 may be located at the top edge of the second partition plate 1252. Alternatively, the first overflow port 1243 may be located at the bottom edge of the second partition plate 1252. Alternatively, the second overflow port 1253 may be located at other positions on the second partition plate 1252.

[0113] like Figure 8 and Figure 9 As 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.

[0114] 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.

[0115] In some embodiments, the exhaust port 1261 can also be used as a heat dissipation vent, allowing air below the bottom of the chassis 12 to enter the housing 1 and dissipate heat from the internal components of the housing 1.

[0116] like Figure 3 , Figure 8 and Figure 9As shown, in some embodiments, the chassis 12 may be provided with a partition rib 123. A mounting groove 1231 may be formed within the partition rib 123. The bottom end of the compressor 21 is installed within the mounting groove 1231. The mounting groove 1231 may be located on the side of the support portion 121 near the first water collection tank 124, allowing the compressor 21 to be arranged in the space of the support plate 72 within the first subspace 110 on the side near the first water collection tank 124.

[0117] In some embodiments, the first water collection tank 124 is disposed adjacent to the outer periphery of the mounting groove 1231. An overflow groove 1232 may be provided at the top edge of the isolation rib 123. The overflow groove 1232 may connect the mounting groove 1231 and the first water collection tank 124. The overflow groove 1232 may connect the mounting groove 1231 and the adjacent first water collection unit 1241. When the water level in the first water collection tank 124 and the first water collection unit 1241 adjacent to the mounting groove 1231 is higher than the overflow groove 1232, excess rainwater or condensate in the first water collection tank 124 may also be discharged into the mounting groove 1231 through the overflow groove 1232, thereby collecting rainwater or condensate in the mounting groove 1231 or discharging it outside the chassis 12 through the mounting groove 1231.

[0118] In some embodiments, a drain outlet may also be provided in the mounting groove 1231. Excess water in the mounting groove 1231 can also be discharged to the outside of the chassis 12 through the corresponding drain outlet.

[0120] In some embodiments, the control box 8 may be disposed within the first subspace 110. The control box 8 may be disposed on the side of the support 121 near the second water collection tank 125. The control box 8 may be supported above the second water collection tank 125. In this way, the control box 8 and the compressor 21 can be arranged on opposite sides of the support 7, which facilitates the rational layout and effective utilization of the internal space of the housing 1.

[0121] like Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, a drainage hole 33 may be provided on the inner bottom surface of the volute structure of the outdoor fan assembly 3. The drainage hole 33 may be located on the inner bottom surface of the volute portion 71, or it may be located on the inner bottom surface of the volute component 31. When it rains outdoors, rainwater can easily enter the interior of the volute structure through the inlet pipe. The rainwater entering the volute structure can be discharged in time through the drainage hole 33, and then flow down through the outer wall of the support member 7 to the chassis 12, where it is collected. Through the design and reasonable arrangement of the drainage structure inside the volute structure, rainwater accumulation inside the volute structure can be effectively prevented, ensuring the stable operation of the outdoor fan assembly 3.

[0122] In some other embodiments, when the air conditioner is heating, the condensate generated in the outdoor fan assembly 3 can also be discharged in time through the drain hole 33. It can flow down through the outer wall of the support 7 to the chassis 12 and be collected on the chassis 12, effectively preventing the condensate from accumulating in the volute structure and ensuring the stable operation of the outdoor fan assembly 3.
