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, a drip tray is usually located below the evaporator, allowing the condensate produced by the evaporator to flow into it. However, the evaporator outlet pipe is quite high above the drip tray, so when the condensate formed on the evaporator outlet pipe drips onto the drip tray, it can easily splash out of the tray and drip down the outer casing onto the ground. Utility Model Content

[0005] The purpose of this invention is to provide an air conditioner that solves the problem of condensate from the evaporator outlet pipe easily splashing out of the drip tray.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, an air conditioner is provided, comprising: a casing forming the outer shell of the air conditioner; an internal receiving space formed within the casing; a refrigerant circulation loop disposed within the receiving space, the refrigerant circulation loop including a compressor, an outdoor heat exchanger, and an indoor heat exchanger connected end-to-end; a first drip tray disposed within the casing, the indoor heat exchanger being disposed above the first drip tray, the first drip tray being used to collect condensate flowing down the outer wall of the indoor heat exchanger; and an indoor fan assembly. The indoor fan assembly is positioned above the first water receiving tray and on one side of the indoor heat exchanger. The indoor heat exchanger has an outlet pipe, which includes: a first pipe section extending downward from the outlet end of the indoor heat exchanger; and a second pipe section extending upward from the bottom end of the first pipe section. A bend is formed at the bend connection between the first pipe section and the second pipe section, and the bend is located at the bottom end of the second pipe section. A water-blocking portion is provided on the outer wall of the indoor fan assembly, and the water-blocking portion is located below the bend.

[0008] The above-mentioned technical solution has the following advantages or beneficial effects: The outdoor heat exchanger and indoor heat exchanger can serve as condensers and evaporators respectively, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thus enabling the air conditioner's cooling or heating cycle. A first drip tray collects the condensate flowing from the outer wall of the indoor heat exchanger. Through the cooperation of the bend and the baffle, the condensate generated on the first and second pipe sections can flow downwards along the outer wall to the bend, dripping from the bottom of the bend onto the baffle, then flowing through the baffle to the outer wall of the indoor fan assembly, and then downwards into the first drip tray. This prevents condensate from the outlet pipe from dripping directly into the first drip tray, thus preventing condensate from splashing out of the drip tray and onto the inner wall of the casing, dripping down the inner wall of the casing to the ground, effectively solving the problem of condensate from the outlet pipe easily splashing out of the drip tray.

[0009] In some embodiments of this application, the vertical distance between the bottom end of the water-blocking portion and the bending portion is less than 50 mm.

[0010] The above-mentioned technical solution has the following advantages or beneficial effects: the vertical distance L between the bottom end of the water-blocking part and the bending part is less than that, which can reduce the height difference between the bottom end of the water-blocking part and the bending part, effectively prevent the condensate dripping from the bottom end of the bending part from splashing on the water-blocking part, and thus avoid the condensate on the water-blocking part from splashing onto the inner wall of the casing.

[0011] In some embodiments of this application, the top surface of the water-blocking portion is formed with a water-blocking slope, and the water-blocking slope extends downward at an inclination toward the direction of the indoor fan assembly; the bent portion is arranged above the water-blocking slope.

[0012] The above-mentioned technical solution has the following advantages or beneficial effects: by arranging the bending part above the water-blocking slope, when the condensate on the bending part can drip onto the water-blocking slope, the condensate can flow down along the water-blocking slope toward the direction close to the indoor fan assembly, flow onto the outer wall of the indoor fan assembly, and then smoothly flow down along the outer wall of the indoor fan assembly to the first water receiving tray.

[0013] In some embodiments of this application, the top of the water-blocking portion is provided with a step portion, which is located at the end of the water-blocking slope away from the indoor fan assembly; there is a height difference between the step portion and the top side edge of the water-blocking slope, and the step portion is higher than the top side edge of the water-blocking slope.

[0014] The above-mentioned technical solution has the following advantages or beneficial effects: Since the step is higher than the top edge of the water-blocking slope, when the condensate on the bend drips onto the water-blocking slope, some of the splashed water can be blocked by the step and fall back onto the water-blocking slope along the side wall of the step, thereby preventing the condensate dripping onto the water-blocking slope from splashing onto the inner wall of the casing.

[0015] In some embodiments of this application, a water-blocking rib is provided on the side edge of the water-blocking slope away from the indoor heat exchanger. The water-blocking rib is arranged obliquely downward along the side edge of the water-blocking slope. The bottom end of the water-blocking rib is connected to the outer wall of the indoor fan assembly, and the top end of the water-blocking rib is connected to the step portion.

[0016] The above-mentioned technical solution has the following advantages or beneficial effects: the water-blocking ribs can be placed on the edge of the water-blocking slope away from the indoor heat exchanger. When condensate drips from the bend onto the water-blocking slope, some of the splashed water can be blocked by the water-blocking ribs and fall back onto the water-blocking slope along the side wall of the ribs, thus preventing the condensate dripping onto the water-blocking slope from splashing onto the inner wall of the casing.

[0017] In some embodiments of this application, the indoor fan assembly includes: an indoor duct housing disposed on one side of the indoor heat exchanger; an indoor impeller rotatably disposed inside the indoor duct housing; an indoor motor, the output end of which is connected to the indoor impeller for driving the indoor impeller to rotate inside the indoor duct housing; and a water baffle disposed on the outer wall of the indoor duct housing.

[0018] The above-mentioned technical solution has the following advantages or beneficial effects: by setting the water baffle on the outer wall of the indoor air duct shell, when the condensate on the outlet pipe of the indoor heat exchanger drips onto the water baffle, it can flow along the water baffle to the outer wall of the indoor air duct shell, and flow downward along the outer wall of the indoor air duct shell, flowing into the first water receiving tray from the bottom of the indoor air duct shell, thereby effectively preventing the condensate from dripping from a height and splashing onto the inner wall of the shell.

[0019] In some embodiments of this application, the indoor air duct housing and the indoor fan wheel are arranged to extend vertically; the indoor motor is located below the bottom of the indoor air duct housing and above the first water receiving tray.

[0020] The above-mentioned technical solution has the following advantages or beneficial effects: the indoor air duct shell and the indoor fan wheel are arranged to extend vertically, and the indoor motor is arranged below the bottom of the indoor air duct shell, which can reduce the horizontal width of the air conditioner and increase the vertical height of the air conditioner, which is conducive to reducing the space occupied by the air conditioner.

[0021] In some embodiments of this application, a fixing rod is provided inside the housing, and the fixing rod extends vertically; the water-blocking part is fixed on the fixing rod.

[0022] The above technical solution has the following advantages or beneficial effects: one side of the outdoor air duct shell can be fixed to the fixing rod by the water-blocking part, thereby improving the structural stability of the water-blocking part and the outdoor air duct shell.

[0023] In some embodiments of this application, one side of the first water receiving tray is fixed to the fixing rod.

[0024] The above-mentioned technical solution has the following advantages or beneficial effects: one side of the first water receiving tray can be fixed to the fixed rod by the water-blocking part, thereby improving the structural stability of the first water receiving tray.

[0025] In some embodiments of this application, the outlet pipe includes a third pipe segment that extends downward from the end of the second pipe segment away from the bend.

[0026] The above-mentioned technical solution has the following advantages or beneficial effects: by extending the third pipe section downward from the end of the second pipe section away from the bend, the condensate generated on the third pipe section can flow downward along the outer wall of the third pipe section, thus facilitating its flow into the water collection tank of the chassis.

Detailed Implementation

[0046] 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.

[0047] 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.

[0048] like Figure 1 and Figure 2As 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.

[0049] 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.

[0050] 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.

[0051] Figure 3 yes Figure 1 The structural diagram with the main shell 11 removed.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Figure 4 yes Figure 2 The structural diagram with the main shell 11 removed.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] Compressor 21 is used to compress refrigerant gas and discharge the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

[0061] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] like Figure 3 and Figure 4 As shown, in some embodiments, the air conditioner may include a second drip tray 5. The second drip tray 5 may be disposed in the receiving space 10 within the casing 1. The second 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 second drip tray 5. The second 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 in heating mode, 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 second drip tray 5 at the bottom of the outdoor heat exchanger 22. The water is collected in the second drip tray 5 or discharged after being collected through the second drip tray 5. This prevents condensate from dripping onto the ground, thus preventing the air conditioner from slipping and the risk of people slipping.

[0079] In some embodiments, the bottom end of the air outlet duct 15 can be arranged in the space above the second water receiving tray 5. When outdoor rainwater enters the housing 1 through the air outlet duct 15, it can be collected by the second 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.

[0080] like Figure 4 As shown, in some embodiments, a drain outlet 51 may be provided on the side wall of the second water receiving tray 5. A drain valve 52 may be provided at the drain outlet 51. The drain valve 52 can block the drain outlet 51. When the drain valve 52 opens the drain outlet 51, the drain outlet 51 can connect to the outside of the second water receiving tray 5, and the water in the second water receiving tray 5 can flow out of the outside of the second water receiving tray 5 through the drain outlet 51.

[0081] like Figure 2 and Figure 4 As shown, in some embodiments, the drain valve 52 can be located outside the housing 1, and the drain outlet 51 can be connected to the outside of the housing 1. When the drain valve 52 opens the drain outlet 51, the water in the second water receiving tray 5 can flow out to the outside of the housing 1 through the drain outlet 51.

[0082] like Figure 3 and Figure 4As shown, in some embodiments, the air conditioner may include a first drip tray 6. The first drip tray 6 may be disposed inside the casing 1. The first 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 first drip tray 6. The first 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, and then falls into the first drip tray 6 at the bottom of the indoor heat exchanger 23. The condensate is collected in the first drip tray 6 or discharged after being collected through the first drip tray 6. This can prevent condensate from dripping onto the ground, causing the air conditioner to slip and the risk of people slipping.

[0083] In some embodiments, the indoor fan assembly 4 may be disposed above the first drip tray 6. The indoor fan assembly 4 may be disposed on one side of the indoor heat exchanger 23 laterally. The first drip tray 6 can be used to provide installation space for the indoor fan assembly 4, so that the indoor fan assembly 4 and the indoor heat exchanger 23 are arranged laterally adjacent to each other, thereby enabling the indoor air introduced by the indoor fan assembly 4 to exchange heat with the indoor heat exchanger 23 nearby, which is beneficial to improving the heat exchange efficiency of the indoor heat exchanger 23.

[0085] like Figure 4 , Figure 5 and Figure 6 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 second drip tray 5, the indoor heat exchanger 23, the indoor fan assembly 4, the first drip tray 6, etc., thereby increasing the structural strength and stability of the air conditioner's internal structure.

[0086] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the lower part of the support member 7 can be located within the first subspace 110, and the bottom end of the support member 7 can be fixed to the chassis 12. The upper part of the support member 7 can be located within the second subspace 120, and the top end of the support member 7 can be supported at the bottom of the first water receiving tray 6, facilitating the installation of the indoor heat exchanger 23 and the indoor fan assembly 4 on the first 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 first 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.

[0087] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the second 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 second water receiving tray 5 and its support and fixation on the support member 7 via the second water receiving tray 5. The outdoor fan assembly 3 can be located on the upper part of the support member 7. In this way, the structural stability of the outdoor heat exchanger 22 and the outdoor fan assembly 3 within the second subspace 120 can be improved.

[0088] 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, second water receiving tray 5, indoor heat exchanger 23, indoor fan assembly 4, and first 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.

[0089] 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.

[0090] like Figure 5 and Figure 6 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 5 and Figure 6 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 5 and Figure 6 As shown, in some embodiments, the outdoor fan assembly 3 may include an outdoor impeller (not shown in the figure). The outdoor impeller can be rotatably disposed within the outdoor duct housing 30, that is, the outdoor impeller can be rotatably disposed within the outdoor duct. The outdoor impeller can be rotatably disposed inside the volute component 31. When the outdoor impeller 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 5 and Figure 6 As 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 via a drive. In this way, the outdoor motor 32 can drive the outdoor impeller 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] like Figure 5 and Figure 6 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.

[0097] 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.

[0098] Figure 7 yes Figure 6 A schematic diagram of the structure of the outdoor heat exchanger 22, the first water receiving tray 6, and the second water receiving tray 5. Figure 8 yes Figure 7 A schematic diagram of its breakdown.

[0099] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the first water receiving tray 6 can be disposed above the top surface of the outdoor heat exchanger 22. The bottom surface of the first water receiving tray 6 can abut against the top surface of the outdoor heat exchanger 22. In this way, the first water receiving tray 6 can be simultaneously supported above the support member 7 and the top of the outdoor heat exchanger 22, improving the stability of the first water receiving tray 6.

[0100] It should be noted that in some other embodiments, there may also be a gap of a certain width between the bottom surface of the first water receiving tray 6 and the top surface of the outdoor heat exchanger 22.

[0101] like Figure 6 and Figure 7 As shown, in some embodiments, the top of the outdoor heat exchanger 22 can abut against the bottom surface of the first water receiving pan 6, and the bottom of the outdoor heat exchanger 22 can be supported on the second water receiving pan 5. In this way, the outdoor heat exchanger 22 can be sandwiched in the area between the first water receiving pan 6 and the second water receiving pan 5, thereby improving the reliability and structural stability of the outdoor heat exchanger 22.

[0102] Figure 9 yes Figure 3 A partial structural diagram. Figure 10 yes Figure 9 A schematic diagram of the structure of the outdoor heat exchanger 22 and the first water receiving tray 6.

[0103] like Figure 7 and Figure 10 As shown, in some embodiments, an outlet 611 may be provided on the inner bottom surface of the first water receiving tray 6. The outlet 611 may be located above the outdoor heat exchanger 22 and the second water receiving tray 5. The outlet 611 may be located above the top surface of the outdoor heat exchanger 22. The condensate in the first water receiving tray 6 can flow downward through the outlet 611, onto the top surface of the outdoor heat exchanger 22, and flow downward along the outer wall of the outdoor heat exchanger 22 to cool it down. Finally, the condensate flows into and is collected in the second water receiving tray 5. In this way, the condensate in the first water receiving tray 6 can be discharged into the second water receiving tray 5 for collection, and heat exchange can be performed between the condensate and the outdoor heat exchanger 22 to cool it down. For example, when the air conditioner is cooling, the outdoor heat exchanger 22, acting as a condenser, needs to dissipate heat to the outside, while the indoor heat exchanger 23, acting 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 first water collection pan 6, and then through the outlet 611 of the first 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 second water collection pan 5 for collection.

[0104] like Figure 8 and Figure 10 As shown, in some embodiments, a first water receiving trough 61 may be provided on the top surface of the first water receiving tray 6. The indoor heat exchanger 23 may be located above the first water receiving trough 61. The water outlet 611 may be located on the bottom surface of the first water receiving trough 61. In this way, the condensate formed on the indoor heat exchanger 23 can fall downward into the first water receiving trough 61 and be discharged downward through the water outlet 611.

[0105] In some embodiments, a second water receiving trough 53 may be provided on the top surface of the second water receiving tray 5. The outdoor heat exchanger 22 may be located above the second water receiving tray 5. The water outlet 611 may be located above the second water receiving trough 53. The drain outlet 51 may be connected to the second water receiving trough 53. In this way, the water discharged downward from the water outlet 611 can flow through the outdoor heat exchanger 22 and finally fall downward into the second water receiving trough 53, making it easy to collect in the second water receiving trough 53, or be discharged through the drain outlet 51.

[0106] like Figure 7 and Figure 8As shown, in some embodiments, a water-spraying wheel 54 may be provided on the second water receiving tray 5. The water-spraying wheel 54 can be rotatably disposed in the second water receiving trough 53. When the water-spraying wheel 54 rotates, it can lift the condensate in the second water receiving trough 53, causing the condensate to splash onto the surface of the outdoor heat exchanger 22, thereby cooling the surface of the outdoor heat exchanger 22. Under the action of gravity, the condensate flows downward along the surface of the outdoor heat exchanger 22 and then falls back into the second water receiving trough 53. The water-spraying wheel 54 can then lift the condensate in the second water receiving trough 53 again, and this process is repeated. This achieves both self-treatment of the condensate in the second water receiving trough 53 and improves the heat exchange efficiency of the outdoor heat exchanger 22.

[0107] In some embodiments, the outdoor heat exchanger 22 may include a first heat exchange section 221 and a second heat exchange section 222. The first heat exchange section 221 and the second heat exchange section 222 may be arranged laterally at a distance. The first heat exchange section 221 and the second heat exchange section 222 may be respectively disposed above the second water receiving tank 53. A water agitator 54 may be disposed at the bottom of the interval area between the first heat exchange section 221 and the second heat exchange section 222. Thus, when the water agitator 54 rotates, it can agitate the condensate in the second water receiving tank 53, causing the condensate to splash onto the surfaces of the first heat exchange section 221 and the second heat exchange section 222, thereby increasing the contact area between the condensate and the outdoor heat exchanger 22 and further improving the heat exchange efficiency of the outdoor heat exchanger 22.

[0108] like Figure 7 and Figure 8 As shown, in some embodiments, a water-spraying motor 55 may be provided on the second water receiving tray 5. The output shaft of the water-spraying motor 55 may be connected to the water-spraying wheel 54 for transmission. The water-spraying motor 55 may be used to drive the water-spraying wheel 54 to rotate within the second water receiving tank 53.

[0109] like Figure 9 and Figure 10 As shown, in some embodiments, the first water receiving tank 61 may have a water outlet 610. A water outlet 611 is located on the bottom surface of the water outlet 610. The water outlet 610 of the first water receiving tank 61 may be located at the lowest point of the first water receiving tank 61. In this way, condensate dripping onto the first water receiving tank 61 can automatically flow to its water outlet 610, allowing the condensate to be smoothly discharged through the water outlet 611, thus improving the drainage efficiency of the first water receiving tank 61.

[0110] like Figure 10As shown, in some embodiments, the first water receiving trough 61 can be elongated. The two opposite ends of the first water receiving trough 61 can be a first end 61a and a second end 61b, respectively. The first end 61a and the second end 61b of the first water receiving trough 61 can be located at opposite ends along the length of the first water receiving trough 61. The water outlet 610 of the first water receiving trough 61 can be located at either the first end 61a or the second end 61b. Specifically, when the water outlet 610 of the first water receiving trough 61 is located at the first end 61a, the first end 61a can be the lowest point of the first water receiving trough 61, and the water outlet 611 can be located on the bottom surface of the first end 61a, such as... Figure 10 As shown. When the outlet end 610 of the first water receiving tank 61 is located at the second end 61b, the second end 61b of the first water receiving tank 61 can be the lowest point of the first water receiving tank 61, and the outlet 611 can be located on the bottom surface of the second end 61b.

[0111] It should be noted that in some other embodiments, the water outlet 610 of the first water receiving tank 61 may also be located in the middle of the first water receiving tank 61 or at other locations.

[0112] Figure 11 yes Figure 10 A structural diagram from another perspective.

[0113] like Figure 10 and Figure 11 As shown, in some embodiments, a water guiding slope 612 may be provided on the bottom surface of the first water receiving tank 61. The water guiding slope 612 may be arranged inclined downwards towards the water outlet 610. In this way, the condensate in the first water receiving tank 61 can flow along the water guiding slope 612 towards the water outlet 610 and flow to the water outlet 611, thereby improving the drainage efficiency of the first water receiving tank 61.

[0114] Figure 12 yes Figure 10 Top view.

[0115] like Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the water outlet 610 of the first water receiving tank 61 may be provided with multiple water outlets 611, which are arranged sequentially adjacent to each other and separated. Separating ribs 613 may be provided between adjacent water outlets 611. Multiple separating ribs 613 may be provided, and they may be sequentially arranged between two adjacent water outlets 611. In this way, the separating ribs 613 can be used to sequentially separate the multiple water outlets 611, making the multiple water outlets 611 sequentially adjacent to each other and separated.

[0116] In some embodiments, the partition rib 613 may protrude from the top opening of the outlet 611. The partition rib 613 may also protrude from the bottom surface of the outlet end 610 of the first water receiving tank 61. One end of the partition rib 613 may extend toward the water guiding slope 612. A water guiding channel 614 may be formed between adjacent partition ribs 613, and one end of the water guiding channel 614 may be connected to a corresponding outlet 611. Multiple partition ribs 613 may form multiple water guiding channels 614, and the multiple water guiding channels 614 may be connected to multiple corresponding outlets 611. In this way, multiple water guiding channels 614 can be formed on the bottom surface of the outlet end 610 of the first water receiving tank 61, so that the condensate flowing from the first water receiving tank 61 to the outlet end 610 can be diverted and discharged through different water guiding channels 614 and corresponding outlets 611. The condensate can be separated independently when entering the corresponding outlets 611, which helps to ensure smooth water flow from each outlet 611, thereby improving the smoothness and efficiency of water flow from the first water receiving tank 61.

[0117] Figure 13 yes Figure 12 Sectional view along line AA.

[0118] like Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, the outlet 611 can be a non-circular hole. The shape of the outlet 611 can be non-circular. Thus, by setting the outlet 611 as a non-circular hole, when condensate water passes through the outlet 611, the non-circular hole can disrupt the surface tension of the condensate water, improve the flow smoothness of the water outlet 611, and help improve the water outlet speed and efficiency of the first water receiving tank 61.

[0119] like Figure 12 As shown, in some embodiments, a drainage groove 615 may be formed on the side edge of the outlet 611 near the guide slope 612. The width of the drainage groove 615 gradually increases in the direction from the guide slope 612 towards the outlet 611. For example, the drainage groove 615 may have a V-shaped groove structure. The tip of the V-shaped groove structure may be arranged towards the guide slope 612. Thus, by providing the drainage groove 615 on the side edge of the outlet 611, the outlet 611 forms a non-circular hole structure, which helps to break the surface tension of the condensate flowing through the outlet 611, improving the drainage speed and water discharge efficiency of the outlet 611. When the condensate from the first water receiving tank 61 flows to the outlet 611 through the guide slope 612, the condensate can preferentially contact the side of the outlet 611 where the guide channel 615 is located, and flow down along the wall of the guide channel 615 into the outlet 611, thereby improving the flow of water from the outlet 611.

[0120] It should be noted that in some other embodiments, the outlet 611 may also adopt a non-circular hole structure of other shapes.

[0121] like Figure 13 As shown, in some embodiments, the top side of the diversion channel 615 is arranged inclined downwards away from the water guiding slope 612. When the condensate from the first water receiving tank 61 flows from the water guiding slope 612 to the outlet 611, the condensate from the first water receiving tank 61 can flow downwards along the wall of the diversion channel 615 into the outlet 611, improving the smoothness and efficiency of the water flow from the outlet 611.

[0122] It should be noted that in some embodiments, the top side surface of the drainage groove 615 can be a flat inclined structure, or the top side surface of the drainage groove 615 can be a smooth arc structure.

[0123] Figure 14 yes Figure 10 A schematic diagram of the first water receiving tray 6 from another perspective.

[0124] like Figure 13 and Figure 14 As shown, in some embodiments, a recessed cavity 62 may be provided on the bottom surface of the first water receiving tray 6. The recessed cavity 62 may be located above the top surface of the outdoor heat exchanger 22. The water outlet 611 may be located on the top side wall of the recessed cavity 62. Thus, through the structural design of the recessed cavity 62, the distance between the water outlet 611 and the top surface of the outdoor heat exchanger 22 can be increased, allowing the water outlet 611 to float above the top surface of the outdoor heat exchanger 22. When the condensate in the first water receiving tray 6 flows downward through the water outlet 611, the condensate needs to flow through the recessed cavity 62 before flowing onto the top surface of the outdoor heat exchanger 22. Since the recessed cavity 62 is located between the outlet 611 and the top surface of the outdoor heat exchanger 22, it is difficult for dust or dirt in the condensate to clog the recessed cavity 62. Therefore, the problem of easy clogging of the outlet 611 can be effectively solved, ensuring smooth drainage of the outlet 611 of the first water receiving pan 6, thereby improving the drainage efficiency and drainage performance of the first water receiving pan 6.

[0125] In some embodiments, the distance h1 between the lower end of the outlet 611 and the top surface of the outdoor heat exchanger 22 can be greater than 1.5 mm. When the clearance cavity 62 has sufficient height, the distance h1 between the lower end of the outlet 611 and the top surface of the outdoor heat exchanger 22 can be greater than 1.5 mm. This maintains a sufficient distance between the outlet 611 and the top surface of the outdoor heat exchanger 22, preventing dust or dirt in the condensate from clogging the space between the lower end of the outlet 611 and the top surface of the outdoor heat exchanger 22, thereby effectively solving the problem of easy clogging of the outlet 611.

[0126] In some embodiments, a downwardly protruding flange 621 may be provided on the top sidewall of the recessed cavity 62. The flange 621 may be provided at the side edge of the lower port of the outlet 611. In this way, by providing the flange 621 at the side edge of the lower port of the outlet 611, so that the bottom end of the flange 621 is lower than the top sidewall of the recessed cavity 62, when water is drained downward from the outlet 611, the condensate can flow downward along the sidewall of the outlet 611 and drip from the bottom surface of the flange 621. It is difficult for the condensate to climb over the flange 621 to the top sidewall of the recessed cavity 62 and then flow out through other sidewalls of the recessed cavity 62, thereby effectively solving and avoiding the problem of water seepage from the outlet 611 to other areas of the outer wall of the water receiving tray.

[0127] like Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the flange 621 can be located below the drainage channel 615. The flange 621 can extend downward from the channel wall of the drainage channel 615. Thus, by extending downward from the channel wall of the drainage channel 615, the flange 621 can be overlapped below the drainage channel 615, making the outline shape of the flange 621 similar to that of the drainage channel 615. When the condensate from the first water receiving tray 6 is discharged through the outlet 611, the condensate can smoothly flow downward along the channel wall of the drainage channel 615 and the side wall of the flange 621, improving the water outlet speed and efficiency of the outlet 611.

[0128] It should be noted that in some other embodiments, the flange 621 may also extend to other side edges of the outlet 611 outside the channel wall of the diversion channel 615.

[0129] In some embodiments, the height h2 of the flange 621 can be greater than 1 mm. Thus, by making the height h2 of the flange 621 greater than 1 mm, the height difference between the bottom surface of the flange 621 and the top sidewall of the clearance cavity 62 can be greater than 1 mm, which can effectively increase the difficulty for the condensate flange 621 to climb onto the top sidewall of the clearance cavity 62, effectively ensuring that the condensate drips from the bottom surface of the flange 621 and preventing the condensate from flowing out through other sidewalls of the clearance cavity 62.

[0130] like Figure 12 , Figure 13 and Figure 14As shown, in some embodiments, at the outlet 611, the bottom of the partition 613 is connected to the flange 621. Thus, at the outlet 611, the bottom of the partition 613 can serve as part of the side edge of the outlet 611, allowing condensate to flow smoothly down the side wall of the partition 613 and drip down from the bottom end of the partition 613 when it is discharged through the outlet 611.

[0131] like Figure 13 As shown, in some embodiments, at the outlet 611, a water-blocking groove 616 may be recessed on the bottom surface of the end of the partition rib 613 away from the flange rib 621. A water-guiding slope 6161 may be formed on the side of the water-blocking groove 616 near the flange rib 621. The water-guiding slope 6161 may be arranged inclined downwards towards the flange rib 621. In this way, by combining the water-blocking groove 616 with the water-guiding slope 6161, the width of the water-blocking groove 616 can gradually increase from top to bottom. When condensate is discharged through the outlet 611, the condensate can flow smoothly downwards along the water-guiding slope 6161 towards the side near the flange rib 621. Only a small portion of the condensate will cross the water-blocking groove 616 and flow downwards from the groove wall of the water-blocking groove 616 away from the water-guiding slope 6161. Therefore, the condensate can be concentrated on the side of the flange rib 621 and flow downwards, improving the drainage smoothness of the outlet 611.

[0132] It should be noted that in some embodiments, the water guiding slope 6161 can be a straight slope structure, or the water guiding slope 6161 can be a smooth arc structure.

[0133] like Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, the first drip tray 6 may be provided with a drip receiving area 63. The drip receiving area 63 may be located on the top surface of the first drip tray 6. The drip receiving area 63 may be located in an area other than the first drip receiving trough 61. The drip receiving area 63 may be located below the outer wall of the indoor fan assembly 4. Condensate on the outer wall of the indoor fan assembly 4 may flow downward into the drip receiving area 63 and be collected in the drip receiving area 63.

[0134] In some embodiments, the water receiving area 63 may be connected to the first water receiving tank 61. A connecting channel 64 may be provided between the water receiving area 63 and the first water receiving tank 61. One end of the connecting channel 64 may be connected to the water receiving area 63, and the other end of the connecting channel 64 may be connected to the first water receiving tank 61. In this way, condensate in the water receiving area 63 can enter the first water receiving tank 61 through the connecting channel 64 and be discharged downward through the outlet 611.

[0135] In some embodiments, the connecting channel 64 may be located between the outlet end 610 of the first water receiving tank 61 and the water receiving area 63. One end of the connecting channel 64 may be connected to the water receiving area 63. The other end of the connecting channel 64 may be connected to any outlet 611 of the outlet end 610. Since the condensate on the outer wall of the indoor fan assembly 4 is less than the condensate on the indoor heat exchanger 23, the condensate in the water receiving area 63 will be significantly less than the condensate in the first water receiving tank 61. By connecting the water receiving area 63 to any outlet 611 through the connecting channel 64, the condensate in the water receiving area 63 can be discharged through the connecting channel 64 and the outlet 611, ensuring the drainage efficiency of the water receiving area 63.

[0136] It should be noted that in some other embodiments, one end of the water receiving area 63 may also be connected to any number of water outlets 611.

[0137] Figure 15 This is a schematic diagram of the structure of the indoor heat exchanger 23, the indoor fan assembly 4, and the first water receiving tray 6 in some embodiments of this utility model. Figure 16 yes Figure 15 A structural diagram from another perspective.

[0138] like Figure 15 and Figure 16 As shown, in some embodiments, the indoor heat exchanger 23 may have an outlet pipe 231. The outlet pipe 231 may be arranged in a top-to-bottom direction. The outlet end of the indoor heat exchanger 23 may communicate with the upper end of the outlet pipe 231. The lower end of the outlet pipe 231 may extend below the first water receiving tray 6 to facilitate communication with the inlet of the compressor 21.

[0139] In some embodiments, the indoor heat exchanger 23 may have multiple outlet ends, and these multiple outlet ends may be combined and connected to the upper end of the outlet pipe 231. The number of outlet ends of the indoor heat exchanger 23 can be adjusted as needed and is not limited herein.

[0140] like Figure 15 and Figure 16 As shown, in some embodiments, the outlet pipe 231 may include a first pipe section 2311. The first pipe section 2311 may be located above the first water receiving pan 6. The first pipe section 2311 may extend downward from the outlet end of the indoor heat exchanger 23. In this way, condensate generated on the first pipe section 2311 can flow downward along the first pipe section 2311 and then flow into the first water receiving pan 6 below.

[0141] In some embodiments, the outlet pipe 231 may include a second pipe section 2312. The second pipe section 2312 may be arranged to bend upward from the bottom end of the first pipe section 2311, such that the height of the end of the second pipe section 2312 connected to the first pipe section 2311 may be lower than the height of the end of the second pipe section 2312 away from the first pipe section 2311. In this way, the condensate generated on the second pipe section 2312 can flow downward along the second pipe section 2312, flow to the end of the second pipe section 2312 connected to the first pipe section 2311, and then drip down from the connection between the first pipe section 2311 and the second pipe section 2312, and then flow into the first water receiving tray 6 below.

[0142] like Figure 15 and Figure 16 As shown, in some embodiments, a bend 2313 may be formed at the bend connection between the first pipe segment 2311 and the second pipe segment 2312. The bend 2313 may be located at the bottom end of the second pipe segment 2312. Thus, the bend 2313 may be located at the end of the second pipe segment 2312 connected to the first pipe segment 2311, and the end of the second pipe segment 2312 away from the first pipe segment 2311 may be the top end of the second pipe segment 2312. Condensate generated on the second pipe segment 2312 may flow downward along the outer wall of the second pipe segment 2312, drip down at the bend 2313, and then flow into the first water receiving tray 6 below. Furthermore, condensate generated on the first pipe segment 2311 may flow downward along the outer wall of the first pipe segment 2311, drip down at the bend 2313, and then flow into the first water receiving tray 6 below.

[0143] In some embodiments, the first pipe segment 2311 and the second pipe segment 2312 can each be a straight pipe structure. The first pipe segment 2311 can be a straight pipe structure extending vertically upwards and downwards. The second pipe segment 2312 can be a straight pipe structure extending obliquely upwards and downwards. The bottom ends of the first pipe segment 2311 and the second pipe segment 2312 can be bent together by a bending portion 2313.

[0144] like Figure 15 and Figure 16 As shown, in some embodiments, the outlet pipe 231 may include a third pipe section 2314. The third pipe section 2314 may extend downward from the end of the second pipe section 2312 away from the bend 2313. Condensate generated on the third pipe section 2314 may flow downward along the outer wall of the third pipe section 2314, thereby facilitating flow to the water collection tank of the chassis 12.

[0145] like Figure 15 and Figure 16As shown, in some embodiments, a water-blocking portion 411 may be provided on the outer wall of the indoor fan assembly 4. The water-blocking portion 411 may be located below the bend portion 2313. In this way, the condensate generated on the first pipe section 2311 and the second pipe section 2312 can flow downward along the outer wall to the bend portion 2313, drip down from the bottom end of the bend portion 2313 onto the water-blocking portion 411, flow through the water-blocking portion 411 to the outer wall of the indoor fan assembly 4, and then flow downward through the outer wall of the indoor fan assembly 4 into the first water receiving tray 6. This can prevent the condensate on the outlet pipe 231 from dripping directly into the first water receiving tray 6, thereby preventing the condensate from splashing out of the water receiving tray and onto the inner wall of the casing 1, and dripping down the inner wall of the casing 1 onto the ground, effectively solving the problem that the condensate on the outlet pipe 231 is prone to splashing out of the water receiving tray.

[0146] Figure 17 yes Figure 15 A side view.

[0147] like Figure 15 and Figure 17 As shown, in some embodiments, the vertical distance L between the bottom end of the water-blocking part 411 and the bottom end of the bending part 2313 can be less than 50 mm. Thus, by making the vertical distance L between the bottom end of the water-blocking part 411 and the bottom end of the bending part 2313 less than 50 mm, the height difference between the bottom end of the water-blocking part 411 and the bottom end of the bending part 2313 can be reduced, effectively preventing condensate dripping from the bottom end of the bending part 2313 from splashing onto the water-blocking part 411, thereby preventing condensate from splashing onto the inner wall of the housing 1. Conversely, if the vertical distance L between the bottom end of the water-blocking part 411 and the bottom end of the bending part 2313 is greater than 50 mm, it cannot be guaranteed that condensate will not splash onto the water-blocking part 411, and it cannot be guaranteed that condensate will not splash onto the inner wall of the housing 1.

[0148] It should be noted that in some other embodiments, the water-blocking part 411 may also contact the bottom end of the bending part 2313. In this case, the vertical distance between the water-blocking part 411 and the bottom end of the bending part 2313 is zero. In this case, the condensate at the bottom end of the bending part 2313 can flow directly onto the water-blocking part 411.

[0149] like Figure 15 , Figure 16 and Figure 17As shown, in some embodiments, the top surface of the water-blocking portion 411 may be formed with a water-blocking slope 4111. The bending portion 2313 may be arranged above the water-blocking slope 4111. The water-blocking slope 4111 may be arranged to extend downward at an angle toward the indoor fan assembly 4. Thus, when condensate on the bending portion 2313 drips onto the water-blocking slope 4111, the condensate can flow downward along the water-blocking slope 4111 toward the indoor fan assembly 4, flowing onto the outer wall of the indoor fan assembly 4, and then smoothly flowing downward along the outer wall of the indoor fan assembly 4 onto the first water receiving tray 6.

[0150] In some embodiments, the top of the water-blocking portion 411 may be provided with a step portion 4112. The step portion 4112 may be located at the end of the water-blocking slope 4111 away from the indoor fan assembly 4. There may be a height difference between the step portion 4112 and the top side edge of the water-blocking slope 4111. The step portion 4112 may be higher than the top side edge of the water-blocking slope 4111. In this way, when condensate on the bend 2313 drips onto the water-blocking slope 4111, some of the splashed water can be blocked by the step portion 4112 and fall back onto the water-blocking slope 4111 along the side wall of the step portion 4112, thereby preventing the condensate dripping onto the water-blocking slope 4111 from splashing onto the inner wall of the housing 1.

[0151] like Figure 15 and Figure 16 As shown, in some embodiments, a water-blocking rib 4113 extending upward may be provided on the side edge of the water-blocking slope 4111 away from the indoor heat exchanger 23. The water-blocking rib 4113 may be arranged obliquely downward along the side edge of the water-blocking slope 4111. The bottom end of the water-blocking rib 4113 may be connected to the outer wall of the indoor fan assembly 4. The top end of the water-blocking rib 4113 may be connected to the step portion 4112. In this way, the water-blocking rib 4113 can block the water on the side edge of the water-blocking slope 4111 away from the indoor heat exchanger 23. When condensate on the bend portion 2313 drips onto the water-blocking slope 4111, some of the splashed water can be blocked by the water-blocking rib 4113 and fall back onto the water-blocking slope 4111 along the side wall of the water-blocking rib 4113, thereby preventing the condensate dripping onto the water-blocking slope 4111 from splashing onto the inner wall of the casing 1.

[0152] It should be noted that, in some embodiments, when condensate water on the bend 2313 drips onto the water-blocking slope 4111, water splashed towards the side closer to the indoor heat exchanger 23 can flow down along the outer wall of the indoor heat exchanger 23 and then onto the first water receiving tray 6; water splashed towards the side farther from the indoor heat exchanger 23 can be blocked by the water-blocking rib 4113 and fall back onto the water-blocking slope 4111; water splashed towards the side closer to the indoor fan assembly 4 can flow down along the outer wall of the indoor fan assembly 4 and then onto the first water receiving tray 6; water splashed towards the side farther from the indoor fan assembly 4 can be blocked by the step portion 4112 and fall back onto the water-blocking slope 4111. In this way, the water-blocking slope 4111 can, to a certain extent, prevent condensate water dripping onto the water-blocking slope 4111 from splashing onto the casing 1.

[0153] Figure 18 yes Figure 16 A schematic diagram of its breakdown.

[0154] like Figure 16 and Figure 18 As shown, in some embodiments, the indoor fan assembly 4 may include an indoor duct housing 41. An indoor duct may be formed inside the indoor duct housing 41. The indoor duct housing 41 may be located on one side of the indoor heat exchanger 23. The indoor heat exchanger 23 may be attached to the outer wall of the indoor duct housing 41. The air inlet of the indoor duct housing 41 may face the indoor heat exchanger 23, and further towards the indoor air inlet 111. The air outlet of the indoor duct housing 41 may face the indoor air outlet 112. Thus, when the indoor fan assembly 4 is running, it draws indoor air into the housing 1 through the indoor air inlet 111, exchanges heat with the indoor heat exchanger 23, and the heat-exchanged air enters the indoor duct housing 41 and is then discharged back into the indoor space outside the housing 1 through the air outlet of the indoor duct housing 41 and the indoor air outlet 112.

[0155] In some embodiments, the bottom end of the indoor duct housing 41 can be mounted on the first drip tray 6. A water-blocking portion 411 can be provided on the outer wall of the indoor duct housing 41. Thus, when condensate from the outlet pipe 231 of the indoor heat exchanger 23 drips onto the water-blocking portion 411, it can flow along the water-blocking portion 411 to the outer wall of the indoor duct housing 41, and then flow downwards along the outer wall of the indoor duct housing 41, flowing from the bottom end of the indoor duct housing 41 into the first drip tray 6, thereby effectively preventing condensate from dripping from a height and splashing onto the inner wall of the housing 1.

[0156] like Figure 16 and Figure 18As shown, in some embodiments, the indoor fan assembly 4 may include an indoor impeller 42. The indoor impeller 42 may be rotatably disposed inside the indoor duct housing 41, that is, the indoor impeller 42 may be rotatably disposed inside the indoor duct. When the indoor impeller 42 rotates, wind force can be generated inside the indoor duct housing 41, so that the air in the indoor space can flow through the indoor air outlet 112, pass through the indoor heat exchanger 23, enter the indoor duct housing 41, and then be discharged into the indoor space outside the housing 1 through the air outlet end of the indoor duct housing 41 and the indoor air outlet 112.

[0157] like Figure 16 and Figure 18 As shown, in some embodiments, the indoor fan assembly 4 may include an indoor motor 43. The output end of the indoor motor 43 may be connected to the indoor impeller 42 for transmission. The indoor motor 43 may be used to drive the indoor impeller 42 to rotate inside the indoor duct housing 41. When the indoor motor 43 drives the indoor impeller 42 to rotate inside the indoor duct housing 41, wind force can be generated inside the indoor duct housing 41, so that the air in the indoor space can flow through the indoor air outlet 112, pass through the indoor heat exchanger 23, enter the indoor duct housing 41, and then be discharged into the indoor space outside the housing 1 through the air outlet of the indoor duct housing 41 and the indoor air outlet 112.

[0158] like Figure 16 and Figure 18 As shown, in some embodiments, the indoor duct housing 41 and the indoor fan 42 can be arranged to extend vertically. The indoor motor 43 can be located below the bottom of the indoor duct housing 41 and above the first water collection tray 6. In this way, the lateral width of the air conditioner can be reduced, while the longitudinal height of the air conditioner can be increased, which helps to reduce the space occupied by the air conditioner.

[0159] like Figure 10 and Figure 18 As shown, in some embodiments, the first water receiving tray 6 may be provided with an installation area 65. The first water receiving trough 61 may be provided on one side of the installation area 65. The bottom end of the indoor air duct housing 41 may be installed in the installation area 65. The first end 61a of the first water receiving trough 61 may be arranged on one side of the installation area 65, and the second end 61b of the first water receiving trough 61 may be bent and extended to be arranged on the adjacent side of the installation area 65. The indoor heat exchanger 23 may extend from the first end 61a of the first water receiving trough 61 to the second end 61b of the first water receiving trough 61 in the lateral direction, so that the indoor heat exchanger 23 can be arranged on the adjacent lateral sides of the indoor air duct housing 41. At this time, the air inlet end of the indoor air duct housing 41 may be provided on the adjacent lateral sides of the indoor air duct housing 41, and thus arranged towards the indoor heat exchanger 23, which is beneficial to the air intake efficiency of the indoor fan assembly 4 and improves the heat exchange efficiency of the indoor heat exchanger 23.

[0160] like Figure 10 and Figure 18 As shown, in some embodiments, the first water receiving tray 6 may be provided with a mounting position 651. The mounting position 651 may be located within the mounting area 65. The indoor motor 43 may be installed in the mounting position 651. The mounting position 651 may be isolated from the first water receiving tank 61 and the water receiving area 63, thereby preventing condensate from entering the mounting position 651 and the indoor motor 43, and preventing condensate from entering the indoor motor 43 and affecting its normal operation.

[0161] 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 6 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 56 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.

[0162] like Figure 3 and Figure 15 As shown, in some embodiments, the water-blocking part 411 can be fixed to the fixing rod 114. In this way, one side of the outdoor air duct housing 30 can be fixed to the fixing rod 114 by the water-blocking part 411, thereby improving the structural stability of the water-blocking part 411 and the outdoor air duct housing 30.

[0163] like Figure 4 , Figure 5 and Figure 6 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.

[0164] like Figure 4 and Figure 5 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.

[0165] like Figure 4 , Figure 5 and Figure 6As 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.
