Description

Technical Field

[0001] This utility model relates to the field of dehumidification technology, and in particular to a dehumidifier. Background Technology

[0002] A dehumidifier is a device that reduces the moisture and humidity in indoor air. Its use is becoming increasingly widespread and important in many public and residential settings.

[0003] A dehumidifier typically consists of a refrigeration system, a housing system, a fan system, and an electronic control system. The refrigeration system includes a compressor, a condenser, and an evaporator. Indoor air is introduced into the housing and exchanges heat with the evaporator and condenser in sequence. Moisture in the introduced air condenses on the evaporator, reducing the humidity of the introduced air. The condenser compensates for the reduced humidity by adjusting the temperature of the air before it is exhausted back into the room through the fan system's outlet.

[0004] Dehumidifiers typically include a drip tray and a drain pump. The drip tray collects the condensate from the evaporator, while the drain pump removes the condensate from the drip tray. When the drain pump starts, hair and other impurities from the drip tray can easily enter the drain pump, causing it to become blocked or jammed. Utility Model Content

[0005] The purpose of this invention is to provide a dehumidifier that can intercept hair and other impurities in the drain pan, reduce the amount of hair and other impurities entering the drain pump, and thus improve the overall reliability of the machine.

[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, a dehumidifier is provided, comprising: a casing forming the outer shell of the dehumidifier; a receiving space provided inside the casing; a refrigerant circulation loop disposed within the receiving space, the refrigerant circulation loop including a compressor, a condenser, and an evaporator connected end-to-end; a water receiving tray disposed below the evaporator, the water receiving tray having a water receiving area and a water pumping area, the bottom surface of the water pumping area being lower than the bottom surface of the water receiving area; and a drain pump disposed in the water pumping area, the drain pump being used to pump water from the water pumping area and discharge it; wherein, the water receiving tray has a fence surrounding the outer periphery of the water pumping area, the fence having a water passage gap connecting the water receiving area and the water pumping area; condensate flowing down from the evaporator can first flow into the water receiving area, and then flow through the water passage gap into the water pumping area.

[0008] The above-mentioned technical solution has the following advantages or beneficial effects: By setting the fence around the outer perimeter of the water pumping area and cooperating with the filter gap, the condensate flowing down from the evaporator can first flow into the water receiving area, and then flow into the water pumping area through the water passage gap in the fence. The fence can intercept impurities such as hair in the water receiving pan, reduce the entry of hair and other impurities into the drain pump, avoid blockage or jamming of the drain pump, and thus improve the reliability of the whole machine.

[0009] In some embodiments of this application, the fence includes: intercepting posts, which extend upward from the inner bottom surface of the water receiving tray, and multiple intercepting posts are provided, which are arranged sequentially at intervals along the periphery of the pumping area; the water passage gap is formed between adjacent intercepting posts.

[0010] The above-mentioned technical solution has the following advantages or beneficial effects: by arranging multiple intercepting columns at intervals along the perimeter of the pumping area, a fence is formed around the pumping area. Water in the receiving area can flow into the pumping area through the area between adjacent intercepting columns. Multiple intercepting columns intercept hair and other impurities in the receiving area, reducing the amount of hair and other impurities entering the pumping area.

[0011] In some embodiments of this application, the fence includes: intercepting ribs, which extend upward from the inner bottom surface of the water receiving tray, extend along the peripheral edge of the pumping area, and surround the outer periphery of the pumping area.

[0012] The above-mentioned technical solution has the following advantages or beneficial effects: By surrounding the water area with intercepting ribs, and with the intercepting ribs extending upward from the inner bottom surface of the water receiving tray, the top height of the intercepting ribs can be higher than the bottom surface of the water receiving area. The intercepting ribs can intercept larger silt or particulate impurities in the water receiving area, causing the silt or particulate impurities to settle on the inner bottom surface of the water receiving area, preventing silt or particulate impurities from entering the pumping area, preventing silt or particulate impurities from entering the drainage pump, and preventing the drainage pump from becoming blocked or jammed.

[0013] In some embodiments of this application, the intercepting post extends upward from the top surface of the intercepting rib.

[0014] The above technical solution has the following advantages or beneficial effects: by extending the intercepting column upward from the top surface of the intercepting rib, the intercepting column and the intercepting rib can be integrally formed, which simplifies the structure of the mold and improves production efficiency.

[0015] In some embodiments of this application, the dehumidifier includes a support plate disposed below the evaporator, and a water receiving tray disposed below the support plate; the support plate has a drain outlet disposed above the water receiving area; the top of the intercepting column extends to the bottom surface of the support plate, so that the water receiving area is enclosed between the bottom surface of the support plate, the inner bottom surface of the water receiving tray, and the fence.

[0016] The above-mentioned technical solution has the following advantages or beneficial effects: by extending the top of the intercepting column to the bottom of the support plate, the water flowing into the water receiving area must be filtered through the fence and flow into the pumping area through the filter gaps between the intercepting columns, thus preventing the water in the water receiving area from crossing the fence and causing impurities to enter the pumping area.

[0017] In some embodiments of this application, a plurality of guide ribs are provided in the water receiving area, and the plurality of guide ribs are arranged at intervals in the water receiving area, and a guide channel is formed between adjacent guide ribs; at least one end of a portion of the guide channel is arranged toward the pumping area, and water in the water receiving area can flow to the pumping area through the guide channel.

[0018] The above-mentioned technical solution has the following advantages or beneficial effects: By using multiple guide ribs, the space within the water receiving area can be divided into multiple guide channels, and the water in the water receiving area can be arranged in multiple guide channels respectively. When the dehumidifier or water tray moves, the guide ribs can restrict the flow of water, so that the water in the water receiving area can be confined within each guide channel, reducing the risk of water overflowing the water tray due to turbulence. In addition, by arranging one end of some guide channels towards the water pumping area, the water in the water receiving area can flow smoothly along the guide channels to the water pumping area.

[0019] In some embodiments of this application, at least one end of the guide rib extends toward the fence and reaches the fence; the end of the guide rib away from the fence is spaced apart from the sidewall of the water-receiving area.

[0020] The above technical solution has the following advantages or beneficial effects: by extending one end of the guide rib to the fence, one end of the guide channel can be arranged towards the pumping area, thereby connecting one end of the guide channel with the pumping area, so that the water in the guide channel can flow smoothly into the pumping area; by arranging the other end of the guide rib at intervals with the side wall of the water-saving area, one end of the guide channel can be connected to the adjacent guide channel through the interval area.

[0021] In some embodiments of this application, the suction port of the drainage pump is arranged downwards and located within the pumping area; the suction port is lower than the bottom surface of the receiving area.

[0022] The above-mentioned technical solution has the following advantages or beneficial effects: by arranging the suction port of the drainage pump in the pumping area and making the suction port lower than the bottom surface of the water receiving area, the suction port of the drainage pump can be lowered, increasing the single pumping capacity of the drainage pump, reducing the number of times the drainage pump is started, and thus reducing the noise generated by the drainage pump.

[0023] In some embodiments of this application, the pumping zone is equipped with a first water level switch and a second water level switch that are signal-connected to the drainage pump. The second water level switch is lower than the first water level switch. The first water level switch is used to control the drainage pump to start, and the second water level switch is used to control the drainage pump to stop. When the first water level switch controls the drainage pump to start, the water level in the receiving pan is at the highest water level line. When the second water level switch controls the drainage pump to stop, the water level in the receiving pan is at the lowest water level line. The suction port is lower than the lowest water level line.

[0024] The above-mentioned technical solution has the following advantages or beneficial effects: The water depth in the pumping zone is relatively deep. Since both the first and second water level switches are located within the pumping zone, it is convenient to set and measure the highest and lowest water level lines in the receiving pan, facilitating the setting of a deeper lowest water level line. Furthermore, by ensuring the suction inlet is lower than the lowest water level line, the risk of leakage at the suction inlet can be reduced, preventing the drainage pump from running dry.

[0025] In some embodiments of this application, the distance between the water intake and the bottom surface of the pumping area is between 3 and 5 mm.

[0026] The above-mentioned technical solution has the following advantages or beneficial effects: by setting the distance between the water inlet and the bottom surface of the pumping area to between 3mm and 5mm, it can not only maintain a sufficient distance between the water inlet and the bottom surface of the pumping area, but also reduce the height of the water inlet, reduce the risk of leakage of the water inlet, and increase the single pumping capacity of the drainage pump.

[0052] Figure 1 This is a structural diagram of a dehumidifier according to some embodiments of the present invention.

[0053] like Figure 1 As shown in some embodiments of the present invention, the dehumidifier includes a housing 1. The housing 1 can be configured as the outer shell of the dehumidifier. The interior of the housing 1 can be used to provide installation space.

[0054] In some embodiments, the housing 1 may have a hollow cuboid structure. The length of the housing 1 may be arranged along the height, allowing the dehumidifier to be installed vertically in the usage area, increasing the height of the dehumidifier and reducing its space occupation. It should be noted that in other embodiments, the external shape of the housing 1 can be designed as needed and is not limited here.

[0055] like Figure 1 As shown, in some embodiments, the dehumidifier may include rollers 13. The rollers 13 may be disposed on the bottom surface of the housing 1. The rollers 13 facilitate the overall movement of the housing 1. Multiple rollers 13 may be provided, and the multiple rollers 13 are arranged at intervals on the bottom surface of the housing 1. The cooperation of multiple rollers 13 can improve the stability of the movement of the housing 1.

[0056] Figure 2 yes Figure 1 An internal structural diagram. Figure 3 yes Figure 2 A structural diagram from another perspective.

[0057] like Figure 2 and Figure 3As shown, in some embodiments, the dehumidifier includes a refrigeration system, which includes a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop includes a compressor 21, a condenser 22, and an evaporator 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, condenser 22, and evaporator 23. The compressor 21 compresses the refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser 22. The condenser 22 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The evaporator 23 evaporates the expanded refrigerant and returns the refrigerant gas, which is in a low-temperature, low-pressure state, to the compressor 21. The evaporator 23 can achieve a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the surrounding environment.

[0058] During the refrigerant cycle, the refrigerant evaporates and absorbs heat in the evaporator 23 and condenses and releases heat in the condenser 22. Indoor air can be introduced into the casing 1, coming into contact with the evaporator 23 and condenser 22 successively. The evaporator 23 condenses and cools the flowing air, and water vapor condenses on the evaporator 23 to form condensate, reducing the humidity and temperature of the air. The condenser 22 reheats the cooled and dehumidified air before discharging it into the room, thereby maintaining a suitable indoor air temperature and adjusting the indoor air humidity.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 1 has a receiving space 10. The refrigerant circulation loop can be located within the receiving space 10. The compressor 21, evaporator 23, and condenser 22 can each be located within the receiving space 10.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the receiving space 10 may be located in the lower space inside the housing 1. Thus, the compressor 21, evaporator 23, and condenser 22 may each be located in the lower space inside the housing 1.

[0061] like Figure 1 and Figure 2 As shown, in some embodiments, an air inlet 101 is provided on the outer wall of the housing 1. The air inlet 101 can be located on the side wall of the housing 1. The air inlet 101 can be located on the side wall of the housing 1 corresponding to the accommodating space 10. The air inlet 101 can be arranged opposite to the evaporator 23. The air inlet 101 can be used to introduce indoor air. Indoor air can enter the housing 1 through the air inlet 101, first contacting the evaporator 23, and then condensing and cooling the introduced indoor air. Water vapor condenses on the evaporator 23 to form condensate, reducing the humidity and temperature of the air.

[0062] like Figure 1As shown, in some embodiments, an air inlet grille 1011 is provided at the air inlet 101. The air inlet grille 1011 can be detachably provided at the air inlet 101. In this way, indoor air can enter the interior of the housing 1 through the grille holes in the air inlet grille 1011. The air inlet grille 1011 can block the air inlet 101, preventing foreign objects from entering the air inlet 101 and contacting the evaporator 23, which helps to improve the safety and stability of the dehumidifier.

[0063] Figure 4 yes Figure 2 Partially decomposed structure diagram.

[0064] like Figure 2 and Figure 4 As shown, in some embodiments, the condenser 22 can be located on one side of the evaporator 23 in the horizontal direction. The condenser 22 can be located on the side of the evaporator 23 away from the air inlet 101. In this way, after indoor air is introduced into the casing 1, it can flow through the evaporator 23 and the condenser 22 in sequence. The evaporator 23 can condense and cool the flowing air, and then the condenser 22 can heat it up before it is discharged back into the room.

[0065] like Figure 1 and Figure 2 As shown, in some embodiments, an air outlet 102 is provided on the outer wall of the housing 1. The air outlet 102 can be located on the side wall of the housing 1. The air outlet 102 can be located on the side wall of the housing 1 corresponding to the accommodating space 10. The air dehumidified by the evaporator 23 and the condenser 22 can flow back into the room through the air outlet 102.

[0066] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the dehumidifier includes a fan assembly 24. The fan assembly 24 is disposed within a receiving space 10 inside the housing 1. The fan assembly 24 may be disposed on one side of the condenser 22 in the horizontal direction. The fan assembly 24 may be disposed on the side of the condenser 22 away from the air inlet 101. The fan assembly 24 may be disposed on the side of the condenser 22 away from the evaporator 23. The air intake 2411 of the fan assembly 24 may be arranged towards the condenser 22, the evaporator 23, and the air inlet 101. The exhaust 2412 of the fan assembly 24 may be arranged opposite to the air outlet 102 of the housing 1. The fan assembly 24 can be used to generate wind power, thereby introducing indoor air into the casing 1, so that the indoor air can smoothly enter the casing 1 through the air inlet 101, flow through the evaporator 23 and condenser 22 in sequence, enter the fan assembly 24 through the air intake 2411, and then be discharged from the casing 1 through the air outlet 2412 and the air outlet 102, thus discharging the air with reduced humidity into the room.

[0067] like Figure 1As shown, in some embodiments, an air outlet grille 1021 is provided at the air outlet 102. The air outlet grille 1021 can be detachably provided at the air outlet 102. In this way, the air dehumidified by the evaporator 23 and condenser 22 can be discharged from the casing 1 through the grille holes of the air outlet grille 1021 and returned to the room. In addition, the air outlet grille 1021 can cover the air outlet 102 to prevent foreign objects from entering the air outlet 102 and contacting the fan assembly 24, which helps to improve the safety and stability of the dehumidifier.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments, the fan assembly 24 includes a duct housing 241. The duct housing 241 may be located on the side of the condenser 22 away from the evaporator 23. An air intake 2411 is located on the side of the duct housing 241 facing the condenser 22. An air exhaust 2412 is located on the side of the duct housing 241 facing the air outlet 102. Indoor air enters the housing 1 through the air intake 101, flows sequentially through the evaporator 23 and the condenser 22, enters the duct housing 241 through the air intake 2411, and is then discharged from the housing 1 through the air exhaust 2412 and the air outlet 102.

[0069] In some embodiments, the fan assembly 24 includes a fan wheel 242. The fan wheel 242 is rotatably disposed within the duct housing 241. The fan wheel 242 is arranged opposite to the air intake 2411. When the fan wheel 242 rotates, the airflow from the fan wheel 242 can discharge the air in the duct housing 241 through the exhaust port 2412 and the outlet port 102 to the casing 1, and generate suction at the air intake 2411, causing indoor air to enter the casing 1 through the air inlet 101, flow sequentially through the evaporator 23 and the condenser 22, and then enter the duct housing 241 through the air intake 2411.

[0070] In some embodiments, the duct housing 241 may be a volute structure. The impeller 242 may be a turbine structure.

[0071] In some embodiments, the fan assembly 24 includes a drive motor 243. The drive motor 243 may be disposed on the inner side wall of the housing 1. The output shaft of the drive motor 243 may be coaxially connected to the impeller 242. When the drive motor 243 is running, the drive motor 243 can drive the impeller 242 to rotate within the duct housing 241, thereby generating wind power within the duct housing 241.

[0072] Figure 5 yes Figure 4 A cross-sectional view.

[0073] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the fan assembly 24 includes a fan shroud 244. The fan shroud 244 may be disposed on the side of the duct housing 241 facing the condenser 22. The fan shroud 244 may be disposed between the duct housing 241 and the condenser 22. An air cavity 2441 may be formed inside the fan shroud 244. The side of the air cavity 2441 near the duct housing 241 is connected to the air intake 2411. An opening is formed on the side of the air cavity 2441 near the condenser 22. The opening of the air cavity 2441 may be arranged opposite to the side wall of the condenser 22 away from the evaporator 23. The opening of the air cavity 2441 may conform to the contour of the condenser 22. The contour of the condenser 22 may conform to the contour of the evaporator 23 and the contour of the air inlet 101. The air cavity 2441 inside the fan cover 244 can smoothly introduce the indoor air flowing through the evaporator 23 and condenser 22 into the air duct shell 241 through the air intake 2411, thereby improving the air intake efficiency of the indoor air, improving the heat exchange efficiency between the indoor air and the evaporator 23 and condenser 22, and thus improving the dehumidification efficiency of the dehumidifier.

[0074] like Figure 4 and Figure 5 As shown, in some embodiments, the dehumidifier includes a drip tray 25. The drip tray 25 may be disposed within a receiving space 10 inside the housing 1. The drip tray 25 may be disposed in the bottom region of the receiving space 10. The drip tray 25 may be disposed below the evaporator 23. The evaporator 23 may be disposed above the drip tray 25. The condenser 22 may be disposed above the drip tray 25. The drip tray 25 can be used to collect condensate flowing down the outer wall of the evaporator 23. The condensate generated on the evaporator 23 can flow downwards along the outer wall of the evaporator 23 and be collected in the drip tray 25.

[0075] In some embodiments, the dehumidifier includes a support plate 26. The support plate 26 may be disposed on top of the drip tray 25. The drip tray 25 may be disposed below the support plate 26. The evaporator 23 may be supported above the support plate 26. The condenser 22 may be supported above the support plate 26. The support plate 26 may be provided with a drain outlet 261. The drain outlet 261 communicates with the interior of the drip tray 25. The condensate generated on the evaporator 23 may flow down the outer wall of the evaporator 23 to the support plate 26, flow to the drain outlet 261, and then flow into the interior of the drip tray 25 through the drain outlet 261. The condensate collects in the drip tray 25.

[0076] like Figure 4 As shown, in some embodiments, the dehumidifier includes a drain pump 27. The drain pump 27 may be disposed in a receiving space 10 within the housing 1. The drain pump 27 may be disposed within a drip tray 25. The drain pump 27 can draw water from the drip tray 25 and discharge the water from the drip tray 25.

[0077] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the dehumidifier includes a water tank 3. The water tank 3 may be located in the top area within the casing 1. The water tank 3 may be located above the accommodating space 10. The water tank 3 is detachably located in the top area of ​​the casing 1. The water volume in the water tank 3 may be larger than the water volume in the drip tray 25. The drain pump 27 can draw water from the drip tray 25 and drain it into the water tank 3 for collection. Users can periodically clean the water tank 3 to drain the condensate generated inside the dehumidifier, thereby ensuring the long-term stable operation of the dehumidifier.

[0078] like Figure 1 and Figure 2 As shown, in some embodiments, the top surface of the water tank 3 is exposed above the top surface of the housing 1. When installing the water tank 3, it can be inserted into the housing 1 from top to bottom. When removing the water tank 3, the user can stand and lift it upwards to remove it from the housing 1. Thus, by placing the water tank 3 in the top area of ​​the housing 1, and using a lifting installation method, the problem of users needing to squat to lift the water tank 3 in other dehumidifiers can be solved, as can the problem of water spillage from the water tank 3, improving the convenience of using the water tank 3.

[0079] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the dehumidifier includes an inner liner 4. The inner liner 4 is disposed inside the housing 1. The inner liner 4 may be disposed in the top region of the housing 1. A receiving space 10 may be formed below the bottom of the inner liner 4. The bottom of the water tank 3 may be supported on the inner liner 4. The peripheral sidewall of the top of the housing 1 covers the outer peripheral wall of the inner liner 4. The inner liner 4 can be used to improve the structural strength of the upper region inside the housing 1, so that the water tank 3 can be stably supported on the inner liner 4. In addition, the peripheral sidewall of the top of the housing 1 covering the outer peripheral wall of the inner liner 4 can also improve the structural strength of the upper region inside the housing 1 and keep the dehumidifier's appearance clean.

[0080] like Figure 4 and Figure 5 As shown, in some embodiments, the dehumidifier includes a water filter 28. The water filter 28 may be disposed in the support plate 26. The water filter 28 may be disposed below the drain outlet 261. Condensate on the evaporator 23 flows downward to the top surface of the support plate 26, and the condensate on the top surface of the support plate 26 can flow to the drain outlet 261, and then flow downward to the lower drip tray 25. When the condensate flows downward through the drain outlet 261, it can be filtered by the water filter 28 before flowing into the drip tray 25, effectively preventing impurities such as lint from entering the drip tray 25.

[0081] In some embodiments, a water filter 28 is detachably disposed below the drain outlet 261. One end of the water filter 28 may protrude from the side wall of the support plate 26. Another end of the water filter 28 may protrude from the side wall of the water receiving tray 25. The water filter 28 can be inserted into the support plate 26 from one side of the support plate 26 and the water receiving tray 25, and then arranged below the drain outlet 261 to facilitate the installation and removal of the water filter 28.

[0082] Figure 6 yes Figure 1 A decomposed structure diagram. Figure 7 yes Figure 6 A decomposed structure diagram.

[0083] like Figure 6 and Figure 7 As shown, in some embodiments, the water filter 28 can be exposed at the air inlet 101, allowing the user to install and remove the water filter 28 from the air inlet 101. Specifically, a detachable air inlet grille 1011 is provided at the air inlet 101, and the water filter 28 is exposed at the air inlet 101, allowing the user to install the water filter 28 and the air inlet grille 1011 sequentially, or to remove the air inlet grille 1011 and the water filter 28 sequentially. When the air inlet grille 1011 is removed from the air inlet 101, the end of the water filter 28 exposed on the support plate 26 can also be exposed at the air inlet 101, facilitating the user to insert the water filter 28 into the support plate 26 through the air inlet 101, or to remove the water filter 28 from the support plate 26 through the air inlet 101. This improves the ease of installation and removal of the water filter 28, facilitates regular cleaning of the water filter 28, and reduces the risk of clogging.

[0084] In addition, when the air inlet grille 1011 is installed at the air inlet 101, the water filter 28 can be encapsulated and shielded inside the air inlet grille 1011, so that the water filter 28 will not be directly exposed to the casing 1. This can keep the dehumidifier's appearance clean and prevent the water filter 28 from being removed at will, which would affect the normal use of the dehumidifier.

[0085] Figure 8 yes Figure 4 Structural diagram of the central water receiving tray 25 and the support plate 26. Figure 9 yes Figure 8 A decomposed structure diagram.

[0086] like Figure 8 and Figure 9As shown, in some embodiments, a handle portion 281 is formed at the end of the water filter 28 exposed above the support plate 26. The handle portion 281 may be exposed on the outer side wall of the support plate 26. The handle portion 281 may be exposed on the outer side wall of the water receiving tray 25. The handle portion 281 can be used to pull the filter. Specifically, the user can hold the handle portion 281 of the water filter 28 to align and insert the water filter 28 into the support plate 26; or hold the handle portion 281 of the water filter 28 to remove the water filter 28 from the support plate 26, further facilitating the installation and removal of the water filter 28.

[0087] In some embodiments, the support plate 26 is detachably mounted on the top of the water tray 25. The side edge of the support plate 26 can be engaged with the side edge of the top of the support plate 26 by means of a snap-fit ​​or similar structure, thereby fixing the support plate 26 to the top of the water tray 25. The support plate 26 can also be removed from the top of the water tray 25 to facilitate installation and removal by the user.

[0088] Figure 10 yes Figure 8 A cross-sectional view.

[0089] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, when the support plate 26 is installed on the top of the water receiving tray 25, the handle portion 281 of the water filter screen 28 can be exposed outside the side wall of the water receiving tray 25. A notch 255 can be provided at the top of the side wall of the water receiving tray 25, and this notch 255 is arranged opposite to the handle portion 281 of the water filter screen 28. When the support plate 26 is installed on the top of the water receiving tray 25, the handle portion 281 can be arranged at the notch 255, and the handle portion 281 can pass through the notch 255 and be exposed outside the outer side wall of the water receiving tray 25.

[0090] In some embodiments, the handle portion 281 is provided with a hand groove 282. At least a portion of the hand groove 282 may protrude from the outer wall of the support plate 26. At least a portion of the hand groove 282 may protrude from the outer wall of the water tray 25. The hand groove 282 facilitates the insertion of the user's fingers, allowing the user to apply force to the handle portion 281 through the hand groove 282, thereby facilitating the alignment and insertion of the water filter screen 28 into the support plate 26, or the removal of the water filter screen 28 from the support plate 26.

[0091] In some embodiments, the handle portion 281 may be provided with a plurality of grip grooves 282. The plurality of grip grooves 282 may be arranged sequentially at intervals along the length direction of the handle portion 281. The plurality of grip grooves 282 may be exposed on the outer wall of the support plate 26. The plurality of grip grooves 282 may be exposed on the outer wall of the water receiving tray 25. The user's fingers may be inserted into the plurality of grip grooves 282, or into any one of the grip grooves 282, allowing the user to apply force to the handle portion 281 through any one of the grip grooves 282, or to apply force to the handle portion 281 simultaneously through the plurality of grip grooves 282.

[0092] Figure 11 yes Figure 9 Structural diagram of the central support plate 26 and the water filter screen 28. Figure 12 yes Figure 11 A structural diagram from another perspective.

[0093] like Figure 7 , Figure 10 and Figure 12 As shown, in some embodiments, the support plate 26 is provided with a groove 262. The groove 262 may be provided on the bottom surface of the support plate 26. The groove 262 may be located on one side below the drain outlet 261. One end of the groove 262 is an open end 2621, and the open end 2621 is provided on the side wall of the support plate 26 near the air inlet 101. The water filter screen 28 can be inserted into the groove 262 through the open end 2621. Since the open end 2621 of the groove 262 is arranged towards the air inlet 101, when the water filter screen 28 is inserted into the groove 262 through the open end 2621, one end of the water filter screen 28 can be exposed outside the open end 2621 of the groove 262, and then exposed outside the outer wall of the support plate 26, and the part of the water filter screen 28 exposed outside the open end 2621 can form a handle portion 281.

[0094] In some embodiments, the support plate 26 may have two grooves 262, which may be located on opposite sides below the drain outlet 261. The open ends 2621 of both grooves 262 are located on the sidewall of the support plate 26. When the water filter screen 28 is inserted into the support plate 26 through the open ends 2621, the opposite ends of the water filter screen 28 can be inserted into one groove 262 respectively. The cooperation of the two grooves 262 allows the opposite ends of the water filter screen 28 to slide along one groove 262, making the sliding installation of the water filter screen 28 smoother and facilitating the easy insertion or removal of the water filter screen 28 from the support plate 26, thus improving the efficiency of installation and removal of the water filter screen 28.

[0095] like Figure 10 and Figure 11As shown, in some embodiments, the top surface of the support plate 26 may be recessed with a drainage groove 260. A drain outlet 261 is formed on the bottom surface of the drainage groove 260. The bottom surface of the drainage groove 260 may be arc-shaped. The height of the arc-shaped central region of the drainage groove 260 is lower than the height of the arc-shaped side regions of the drainage groove 260. By creating the arc shape of the drainage groove 260, a structure that is low in the middle and high on both sides is formed, facilitating the flow of condensate from the support plate 26 to the drainage groove 260, and then to the arc-shaped central region of the drainage groove 260, thus smoothly flowing through the drain outlet 261 into the water receiving tray 25 below, preventing condensate from overflowing outside the drainage groove 260.

[0096] like Figure 4 and Figure 11 As shown, in some embodiments, the drain trough 260 can extend along the length of the evaporator 23. The arcuate direction of the drain trough 260 is arranged along the width of the evaporator 23. Multiple drain outlets 261 can be provided, and these outlets 261 can be arranged sequentially and at intervals along the length of the evaporator 23 on the bottom surface of the drain trough 260. A water filter screen 28 can extend along the length of the evaporator 23, and the water filter screen 28 can be arranged below the drain trough 260 and below the multiple drain outlets 261. By extending the drain groove 260 along the length of the evaporator 23, the drain groove 260 can be widened along the length of the evaporator 23, thereby creating multiple drain outlets 261 along the length of the evaporator 23. This improves the water leakage efficiency at the drain outlets 261 and increases the contact area with the water filter screen 28. In addition, the water filter screen 28 can be extended and widened along the length of the evaporator 23, greatly increasing the filtration area of ​​the water filter screen 28, improving the filtration efficiency of the water filter screen 28, and reducing the frequency of cleaning the water filter screen 28 by the user.

[0097] like Figure 10 and Figure 12 As shown, in some embodiments, the chute 262 has an arc-shaped structure and is located below the bottom surface of the arc-shaped groove of the drain trough 260. The height of the arc-shaped central region of the chute 262 can be lower than the height of the arc-shaped end regions of the chute 262, creating a structure that is low in the middle and high on both sides. The opening end 2621 of the chute 262 can be located at one end of the arc of the chute 262. Through the arc-shaped structure of the chute 262, the shape of the chute 262 can be adapted to the shape of the drain trough 260. When the water filter 28 is inserted into the chute 262, the water filter 28 can be bent to form an arc-shaped structure, so that the arc-shaped water filter 28 can be attached to the lower side of the arc-shaped drain trough 260, improving the filtration efficiency of the water filter 28 at the drain outlet 261.

[0098] like Figure 5 and Figure 10As shown, in some embodiments, the evaporator 23 and condenser 22 can be arranged side-by-side above the support plate 26. A portion of the drain groove 260 is located below the evaporator 23, and another portion extends below the condenser 22. Multiple drain outlets 261 can be provided, and these outlets can be arranged sequentially at intervals along the arcuate direction of the drain groove 260. Some outlets 261 can be located below the evaporator 23, and some outlets 261 can be located below the condenser 22. By arranging the evaporator 23 and condenser 22 side-by-side above the support plate 26, the drain groove 260 on the top surface of the support plate 26 can extend below the condenser 22, thereby increasing the area of ​​the drain groove 260. This facilitates increasing the number of drain outlets 261 and the area of ​​the water filter screen 28, improving the filtration efficiency of the water filter screen 28, and reducing the frequency of user cleaning of the water filter screen 28.

[0099] like Figure 5 and Figure 9 As shown, in some embodiments, the top surface of the support plate 26 may be recessed with a first water flow channel 263. The first water flow channel 263 may be located below the evaporator 23. The first water flow channel 263 may communicate with the drain trough 260, allowing water in the first water flow channel 263 to flow into the drain trough 260. Because the first water flow channel 263 is located below the evaporator 23, the condensate flowing down from the evaporator 23 can flow into the first water flow channel 263, along the first water flow channel 263 to the drain trough 260, and then through the drain outlet 261 on the bottom surface of the drain trough 260 to the water receiving tray 25 below.

[0100] In some embodiments, the top surface of the support plate 26 may be recessed with a second water flow channel 264. The second water flow channel 264 may be located below the condenser 22 and may communicate with the drain trough 260, allowing water in the second water flow channel 264 to flow into the drain trough 260. Because the second water flow channel 264 is located below the condenser 22, some of the condensate from the condenser 22 can flow downwards into the second water flow channel 264, flow along the second water flow channel 264 into the drain trough 260, and then flow through the drain outlet 261 on the bottom surface of the drain trough 260 into the water receiving tray 25 below.

[0101] like Figure 5 and Figure 8As shown, in some embodiments, a baffle 265 may be provided on the edge of the drain trough 260 facing the air intake 2411. The baffle 265 has a notch 2651, through which the second water flow channel 264 can communicate with the drain trough 260. A windbreak 266 may be provided inside the drain trough 260, with the windbreak 266 and the notch 2651 arranged at intervals opposite each other. The notch 2651 connects the second water flow channel 264 and the drain trough 260. With the windbreak 266 and the notch 2651 arranged at intervals opposite each other, when the fan assembly 24 is running, the windbreak 266 can block the side of the notch 2651 near the air intake 101, thereby preventing air leakage at the notch 2651.

[0102] In some embodiments, the wind baffle 266 may extend upward from the bottom surface of the drain groove 260. The wind baffle 266 may extend along the length of the condenser 22. The wind baffle 266 is located in the area between adjacent drain outlets 261 to prevent obstruction of water leakage at the drain outlets 261. The wind baffle 266 may be arranged below the bottom surface of the condenser 22. The bottom surface of the condenser 22 may be supported on the top surface of the wind baffle 266, thereby preventing air leakage in the top area of ​​the wind baffle 266.

[0103] like Figure 8 and Figure 9 As shown, in some embodiments, the support plate 26 may be provided with an overflow hole 267. The overflow hole 267 can connect to the interior of the water receiving tray 25. The overflow hole 267 can be higher than the drain outlet 261. The overflow hole 267 can be higher than the drain trough 260. When the drain outlet 261 is blocked, the water overflowing from the drain trough 260 can flow into the water receiving tray 25 below through the overflow hole 267, preventing water from overflowing from the edge of the support plate 26.

[0104] like Figure 9 and Figure 10 As shown, in some embodiments, a maximum water level line L1 may be provided in the water receiving tray 25. When the water level in the water receiving tray 25 is higher than the maximum water level line L1, the drain pump 27 can draw and discharge the water in the water receiving tray 25, so that the water level in the water receiving tray 25 is always below the maximum water level line L1, and the water in the water receiving tray 25 will not exceed the maximum water level line L1, thereby preventing the water level in the water receiving tray 25 from being too high and overflowing.

[0105] In some embodiments, a first water level switch 291 may be provided inside the water receiving tray 25. The first water level switch 291 can be signal-connected to the drain pump 27 and can be used to control the drain pump 27 to start. When the first water level switch 291 controls the drain pump 27 to start, the water level in the water receiving tray 25 is at the highest water level line L1. Specifically, when the water level in the water receiving tray 25 rises to the highest water level line L1, the first water level switch 291 can generate a control signal to be transmitted to the drain pump 27, thereby controlling the drain pump 27 to start, so that the drain pump 27 can draw and discharge water from the water receiving tray 25, thereby keeping the water level in the water receiving tray 25 always below the highest water level line L1.

[0106] In some embodiments, the first water level switch 291 may be a float switch. The upper part of the first water level switch 291 may be fixed to the support plate 26. The lower part of the first water level switch 291 may extend downward into the water receiving tray 25.

[0107] like Figure 9 and Figure 10 As shown, in some embodiments, the water filter screen 28 is spaced above the highest water level line L1. There is a certain distance between the bottom surface of the water filter screen 28 and the highest water level line L1. This distance can be a preset distance, meaning the distance between the lowest point of the bottom surface of the water filter screen 28 and the highest water level line L1 is a preset distance. By spaced the water filter screen 28 above the highest water level line L1, a certain distance is maintained between the water filter screen 28 and the highest water level line L1 set on the water receiving tray 25, keeping it above the preset distance. This achieves the effect of the water filter screen 28 being suspended, preventing the mesh of the water filter screen 28 from being soaked in the water of the water receiving tray 25 for a long time. This prevents the water filter screen 28 from growing mold and other flocculent matter due to prolonged soaking, thus avoiding accelerated clogging of the water filter screen 28.

[0108] like Figure 9 and Figure 10 As shown, in some embodiments, a minimum water level line L2 may be provided in the water receiving tray 25. When the water level in the water receiving tray 25 is lower than the minimum water level line L2, the drain pump 27 can stop pumping water, so that the water level in the water receiving tray 25 is kept above the minimum water level line L2. At this time, the suction port 271 of the drain pump 27 is lower than the minimum water level line L2. The suction port 271 can be located in the area below the minimum water level line L2, thereby preventing the drain pump 27 from running dry.

[0109] In some embodiments, a second water level switch 292 may be provided in the water receiving tray 25. The second water level switch 292 can be used to control the drainage pump 27 to shut down. The second water level switch 292 can be signal-connected to the drainage pump 27. When the second water level switch 292 controls the drainage pump 27 to shut down, the water level in the water receiving tray 25 is at the lowest water level line L2. Specifically, when the water level in the water receiving tray 25 drops to the lowest water level line L2, the second water level switch 292 can generate a control signal to be transmitted to the drainage pump 27, thereby controlling the drainage pump 27 to shut down, so that the drainage pump 27 can stop pumping water, thereby keeping the water level in the water receiving tray 25 above the lowest water level line L2.

[0110] In some embodiments, the second water level switch 292 may be a float switch. The upper part of the second water level switch 292 may be fixed to the support plate 26. The lower part of the second water level switch 292 may extend downward into the water receiving tray 25. The second water level switch 292 may be lower than the first water level switch 291.

[0111] Figure 13 yes Figure 8 Structural diagram of the intermediate water tray 25 and the drainage pump 27. Figure 14 yes Figure 13 A top view.

[0112] like Figure 13 and Figure 14 As shown, in some embodiments, the water receiving tray 25 is provided with a water receiving area 251. A drain outlet 261 can be arranged above the water receiving area 251, and a water filter screen 28 can be arranged above the water receiving area 251. Condensate flowing down from the evaporator 23 can flow into the water receiving area 251. Specifically, the condensate on the evaporator 23 can flow downwards to the top surface of the support plate 26, flow downwards through the drain outlet 261, be filtered by the water filter screen 28, and then flow into the water receiving area 251.

[0113] In some embodiments, a pumping zone 252 is provided within the water receiving tray 25. The bottom surface of the pumping zone 252 is lower than the bottom surface of the water receiving zone 251. A drain pump 27 can be provided in the pumping zone 252, and the drain pump 27 can be used to pump out and discharge the water in the pumping zone 252. The condensate flowing down from the drain outlet 261 can first flow into the water receiving zone 251, then into the pumping zone 252, and then be discharged by the pump. By providing a water receiving zone 251 and a pumping zone 252 within the water receiving tray 25, and utilizing the fact that the bottom surface of the pumping zone 252 is lower than the bottom surface of the water receiving zone 251, the condensate flowing down from the evaporator 23 can first flow down into the water receiving zone 251 through the drain outlet 261, and then flow from the water receiving zone 251 into the pumping zone 252, causing the condensate to collect in the pumping zone 252, thus making the water depth in the pumping zone 252 deeper, facilitating the pump to pump out and discharge it.

[0114] like Figure 13 and Figure 14 As shown, in some embodiments, both the first water level switch 291 and the second water level switch 292 are located within the pumping zone 252. The second water level switch 292 and the first water level switch 291 can be arranged alternately to avoid mutual interference between them. Since the water depth in the pumping zone 252 is relatively deep, the location of both the first and second water level switches 291 within the pumping zone 252 facilitates the setting and measurement of the highest water level line L1 and the lowest water level line L2 within the receiving tray 25, and also facilitates the setting of a deeper lowest water level line L2.

[0115] like Figure 10 and Figure 14 As shown, in some embodiments, a limiting rib 2511 may be provided in the water receiving area 251, and the limiting rib 2511 is located below the bottom surface of the water filter screen 28. The limiting rib 2511 may be located below the center of the bottom of the water filter. The limiting rib 2511 may extend upward from the bottom surface of the water receiving area 251. The top of the limiting rib 2511 may be in clearance fit with the bottom surface of the water filter screen 28. Through the clearance fit between the top of the limiting rib 2511 and the bottom surface of the water filter screen 28, when the water filter screen 28 bends and deforms downward due to water flow impact or the gravity of impurities, the top of the limiting rib 2511 can be supported below the bottom surface of the water filter screen 28, preventing the water filter screen 28 from excessively bending and deforming, and also preventing the bottom surface of the water filter screen 28 from being immersed in the water in the water receiving tray 25.

[0116] It should be noted that in some other embodiments, the limiting rib 2511 may also be provided in other areas within the water receiving tray 25.

[0117] like Figure 10 and Figure 14 As shown, in some embodiments, a plurality of guide ribs 2512 may be provided in the water receiving area 251. These guide ribs 2512 may be arranged at intervals within the water receiving area 251, and guide channels 2513 are formed between adjacent limiting ribs 2511. At least one end of a portion of the guide channels 2513 may be arranged towards the water pumping area 252, allowing water in the water receiving area 251 to flow into the water pumping area 252 through the guide channels 2513. Through the cooperation of the multiple guide ribs 2512, the space within the water receiving area 251 can be divided into multiple guide channels 2513, and the water in the water receiving area 251 can be arranged separately within each of the multiple guide channels 2513. When the dehumidifier or the water tray 25 moves, the guide ribs 2512 can restrict the flow of water, confining the water in the water receiving area 251 within each guide channel 2513, thus reducing the risk of water overflowing from the water tray 25 due to turbulent flow. In addition, by arranging one end of a partial guide channel 2513 toward the pumping area 252, water in the receiving area 251 can flow smoothly along the guide channel 2513 into the pumping area 252.

[0118] Figure 15 yes Figure 13 A structural diagram from another perspective.

[0119] like Figure 13 and Figure 15 As shown, in some embodiments, a fence 253 may be provided inside the water receiving tray 25, surrounding the outer perimeter of the pumping area 252. The fence 253 may be located at the dividing area between the pumping area 252 and the water receiving area 251. A water passage gap 2530 is provided in the fence 253, which can connect the water receiving area 251 and the pumping area 252. By placing the fence 253 around the outer perimeter of the pumping area 252, in conjunction with the filter gap, the condensate flowing down from the evaporator 23 can first flow into the water receiving area 251, and then flow into the pumping area 252 through the water passage gap 2530 in the fence 253. The fence 253 can intercept impurities such as hair in the water receiving tray 25, reducing the amount of hair and other impurities entering the drain pump 27, preventing the drain pump 27 from blocking or jamming, thereby improving the reliability of the entire machine.

[0120] In some embodiments, the fence 253 may include intercepting posts 2531. The intercepting posts 2531 may extend upwards from the inner bottom surface of the water receiving tray 25. Multiple intercepting posts 2531 may be arranged sequentially and spaced apart along the periphery of the pumping area 252. Water passage gaps 2530 may be formed between adjacent intercepting posts 2531. By sequentially and spaced apart along the periphery of the pumping area 252, a fence 253 is formed around the pumping area 252. Water in the receiving area 251 can flow into the pumping area 252 through the area between adjacent intercepting posts 2531. The multiple intercepting posts 2531 intercept impurities such as hair within the receiving area 251, reducing the amount of hair and other impurities entering the pumping area 252.

[0121] In some embodiments, the intercepting post 2531 may be disposed at the side edge of the water receiving area 251 near the water pumping area 252, and the intercepting post 2531 may extend upward from the inner bottom surface of the water receiving area 251. It should be noted that in other embodiments, the intercepting post 2531 may also be disposed at the side edge of the water pumping area 252 near the water receiving area 251, and the intercepting post 2531 may also extend upward from the inner bottom surface of the water pumping area 252.

[0122] like Figure 13 and Figure 15As shown, in some embodiments, the fence 253 may include intercepting ribs 2532, which may be disposed at the side edge of the water receiving area 251 near the pumping area 252. The intercepting ribs 2532 may extend upward from the inner bottom surface of the water receiving tray 25. The intercepting ribs 2532 may extend along the peripheral side edge of the pumping area 252, and may surround the outer perimeter of the water area. By surrounding the water area with intercepting ribs 2532, and extending upwards from the inner bottom surface of the water receiving tray 25, the top height of the intercepting ribs 2532 can be higher than the bottom surface of the water receiving area 251. The intercepting ribs 2532 can intercept larger silt or particulate impurities in the water receiving area 251, causing the silt or particulate impurities to settle on the inner bottom surface of the water receiving area 251, preventing silt or particulate impurities from entering the pumping area 252, and preventing silt or particulate impurities from entering the drainage pump 27, thus preventing the drainage pump 27 from blocking or jamming.

[0123] In some embodiments, the intercepting post 2531 can be arranged to extend upward from the top surface of the intercepting rib 2532, so that the intercepting post 2531 and the intercepting rib 2532 can be integrally formed, which simplifies the structure of the mold and improves production efficiency.

[0124] like Figure 13 and Figure 14 As shown, in some embodiments, the intercepting column 2531 can be arranged in an arc shape. The sidewall of the intercepting column 2531 facing the water-receiving area 252 protrudes in an arc shape, forming an arc-shaped wall 25311. The opposite two sides of the arc-shaped wall 25311 can be bent towards the water-receiving area 251. The sidewall of the intercepting column 2531 facing the water-receiving area 251 is recessed with an arc-shaped intercepting groove 25312. Through the arc-shaped structural design of the intercepting column 2531, the width of the water-passing gap 2530 gradually increases in the direction from the water-receiving area 251 towards the water-receiving area 252. Combined with the structure of the intercepting groove 25312, impurities such as lint can be better intercepted in the water-receiving area 251, improving the interception efficiency of lint and other impurities.

[0125] like Figure 13 and Figure 14As shown, in some embodiments, at least one end of the guide rib 2512 can extend toward and to the fence 253. For example, one end of the guide rib 2512 can extend to the intercepting rib 2532 or the intercepting post 2531. The end of the guide rib 2512 away from the fence 253 can be spaced apart from the side wall of the water receiving area 251. By extending one end of the guide rib 2512 to the fence 253, one end of the guide channel 2513 can be arranged toward the pumping area 252, thereby connecting one end of the guide channel 2513 with the pumping area 252, allowing water in the guide channel 2513 to flow smoothly into the pumping area 252; by spaced apart from the other end of the guide rib 2512 with the side wall of the water-saving area, one end of the guide channel 2513 can connect to an adjacent guide channel 2513 through the spaced area.

[0126] Figure 16 yes Figure 14 A cross-sectional view.

[0127] like Figure 10 and Figure 16 As shown, in some embodiments, the top of the intercepting column 2531 can extend to the bottom surface of the support plate 26, so that the water receiving area 251 is surrounded between the bottom surface of the support plate 26, the inner bottom surface of the water receiving tray 25, and the fence 253. By extending the top of the intercepting column 2531 to the bottom surface of the support plate 26, the water flowing into the water receiving area 251 must be filtered through the fence 253 and flow into the pumping area 252 through the filtration gaps between the intercepting columns 2531, preventing the water in the water receiving area 251 from crossing the fence 253 and causing impurities to enter the pumping area 252.

[0128] like Figure 15 and Figure 16 As shown, in some embodiments, the suction port 271 of the drain pump 27 can be arranged downwards, with the suction port 271 located within the pumping area 252, below the bottom surface of the receiving area 251. By oriented the suction port 271 within the pumping area 252, the drain pump 27 can draw water from and discharge it from the pumping area 252 without requiring a suction pipe, thus reducing the risk of leakage and simplifying the installation process. Furthermore, by positioning the suction port 271 below the bottom surface of the receiving area 251, the suction port 271 can be lowered, increasing the single-pump capacity of the drain pump 27, reducing the number of times the drain pump 27 is started, and consequently reducing the noise generated by the drain pump 27.

[0129] like Figure 16As shown, in some embodiments, the distance between the suction port 271 and the bottom surface of the pumping zone 252 is D1, which can be greater than or equal to 3 mm. By ensuring that the distance between the suction port 271 and the bottom surface of the pumping zone 252 is greater than or equal to 3 mm, sufficient distance is maintained between them, avoiding any impact on the suction speed of the drain pump 27. If the distance between the suction port 271 and the bottom surface of the pumping zone 252 is less than 3 mm, the suction speed of the drain pump 27 will be significantly reduced.

[0130] In some embodiments, the distance D1 between the suction port 271 and the bottom surface of the pumping zone 252 can be less than or equal to 5 mm. By making the distance between the suction port 271 and the bottom surface of the pumping zone 252 less than or equal to 5 mm, the suction port 271 of the drain pump 27 can be lowered, reducing the height of the suction port 271, reducing the risk of leakage of the suction port 271, and increasing the single pumping capacity of the drain pump 27.

[0131] In some embodiments, the distance D1 between the suction port 271 and the bottom surface of the pumping zone 252 is set between 3mm and 5mm. By setting the distance between the suction port 271 and the bottom surface of the pumping zone 252 between 3mm and 5mm, sufficient distance can be maintained between the suction port 271 and the bottom surface of the pumping zone 252 to avoid affecting the water suction speed of the drain pump 27; at the same time, the height of the suction port 271 can be reduced to reduce the risk of leakage from the suction port 271.

[0132] like Figure 16 As shown, in some embodiments, the suction port 271 is lower than the lowest water level line L2, and the distance D2 between the lowest water level line L2 and the suction port 271 is greater than or equal to 10 mm. By ensuring that the distance D2 between the lowest water level line L2 and the suction port 271 is greater than or equal to 10 mm, the position of the suction port 271 can be kept sufficiently deep, which helps to reduce the risk of leakage from the suction port 271 and prevent the drain pump 27 from running dry.

[0133] like Figure 16 As shown, in some embodiments, the top surface of the drain pump 27 is higher than the highest water level line L1, and the distance D3 between the top surface of the drain pump 27 and the highest water level line L1 is greater than or equal to 5mm. By ensuring that the top surface of the drain pump 27 is at least 5mm higher than the highest water level line L1, it is possible to prevent the water in the water receiving tray 25 from overflowing the top surface of the drain pump 27 and to prevent the water in the water receiving tray 25 from submerging the drain pump 27.

[0134] Figure 17 yes Figure 13 A decomposed structure diagram. Figure 18 yes Figure 17 Structural diagram of drainage pump 27.

[0135] like Figure 17 and Figure 18As shown, in some embodiments, a fixing part 254 may be provided within the pumping zone 252. The fixing part 254 may be columnar and may extend from the bottom surface of the pumping zone 252. A support arm 273 may be provided on the outer wall of the drain pump 27, and the end of the support arm 273 is fixed to the fixing part 254 by a shock-absorbing pad 274. By cooperating with the support arm 273, the shock-absorbing pad 274 and the fixing part 254, the drain pump 27 can be fixed within the pumping zone 252, and the shock absorption performance of the drain pump 27 can be improved, reducing the noise generated by the drain pump 27 when pumping water.

[0136] In some embodiments, two fixing parts 254 may be provided, and the two fixing parts 254 may be respectively disposed on opposite sides of the drain pump 27. Two support arms 273 may be provided, and the two support arms 273 may be respectively disposed on the outer walls of opposite sides of the drain pump 27. The two support arms 273 are respectively arranged correspondingly to the two fixing parts 254. Two shock-absorbing pads 274 may be provided, and the two support arms 273 are respectively fixed to the corresponding fixing parts 254 by a shock-absorbing pad 274. By cooperating with the two fixing parts 254 on opposite sides of the drain pump 27 and the two support arms 273, the stability of the drain pump 27 fixed in the pumping area 252 can be improved.

[0137] It should be noted that in some other embodiments, three or more fixing parts 254 may be provided, and these three or more fixing parts 254 may be arranged at intervals around the outer periphery of the drain pump 27. Correspondingly, three or more support arms 273 may be provided on the outer wall of the drain pump 27, and these three or more support arms 273 may be arranged at intervals around the outer periphery of the drain pump 27. The number of support arms 273 may correspond to the number of fixing parts 254, thereby improving the fixing stability of the drain pump 27.

[0138] like Figure 17 and Figure 18 As shown, in some embodiments, a fixing post 2541 may be provided on the top of the fixing part 254, and the fixing post 2541 extends upward from the top surface of the fixing part 254. A connecting groove 2741 may be provided at the end of the shock-absorbing pad 274 away from the drainage pump 27. The shock-absorbing pad 274 is fitted onto the outer periphery of the fixing post 2541 through the connecting groove 2741 and supported on the top surface of the fixing part 254. By providing a fixing post 2541 on the top of the fixing part 254, and cooperating with the connecting groove 2741 on the shock-absorbing pad 274, the end of the support arm 273 can be fitted onto the outer periphery of the fixing post 2541 through the connecting groove 2741 of the shock-absorbing pad 274 and supported on the top surface of the fixing part 254. This improves both the connection stability between the support arm 273 and the fixing part 254 and the shock-absorbing performance of the shock-absorbing pad 274.

[0139] Figure 19 yes Figure 18 A decomposed structure diagram. Figure 20 yes Figure 19 A top view.

[0140] like Figure 19 and Figure 20 As shown, in some embodiments, the end of the support arm 273 furthest from the drain pump 27 may be recessed with a limiting groove 2731. One end of the limiting groove 2731 furthest from the drain pump 27 forms a limiting opening 2732. A shock-absorbing pad 274 can extend into the limiting groove 2731 through the limiting opening 2732 and be fixed to the peripheral edge of the limiting groove 2731. The structure of the limiting groove 2731 and the limiting opening 2732 allows the shock-absorbing pad 274 to be stably fixed to the end of the support arm 273. When the shock-absorbing pad 274 is fitted onto the outer periphery of the fixing post 2541 through the connecting groove 2741, the areas of the support arm 273 located on opposite sides of the limiting opening 2732 can be clamped and fitted onto the outer periphery of the fixing post 2541 and supported on the top surface of the fixing part 254, improving the connection stability between the support arm 273 and the fixing part 254.

[0141] In some embodiments, a claw 2733 may be formed on each of the opposite sides of the limiting opening 2732. When the shock-absorbing pad 274 extends into the limiting groove 2731 and is fixed at the peripheral edge of the limiting groove 2731, the shock-absorbing pad 274 can cover the claw 2733. When the shock-absorbing pad 274 is sleeved on the outer periphery of the fixing post 2541 through the connecting groove 2741, the two claws 2733 on the opposite sides of the limiting opening 2732 can clamp on both sides of the fixing post 2541 and support on the top surface of the fixing part 254, thereby improving the connection stability between the support arm 273 and the fixing part 254.

[0142] like Figure 19 and Figure 20 As shown, in some embodiments, an anti-disengagement buckle 2734 is provided on each of the opposite sides of the limiting port 2732. The anti-disengagement buckle 2734 can protrude from the side of the claw 2733 facing the limiting port 2732. A limiting buckle 2735 can protrude from the inner wall of the limiting groove 2731, and the limiting buckle 2735 can be provided on the side of the inner wall of the limiting groove 2731 away from the limiting port 2732. When the shock-absorbing pad 274 is assembled in the limiting groove 2731, the inside of the shock-absorbing pad 274 can be engaged with the anti-disengagement buckle 2734 and the limiting buckle 2735 respectively. By engaging the inside of the shock-absorbing pad 274 with two anti-disengagement buckles 2734 and one limiting buckle 2735 respectively, the shock-absorbing pad 274 can be stably fixed in the limiting groove 2731, improving the connection stability between the shock-absorbing pad 274 and the support arm 273.

[0143] like Figure 16 , Figure 18 and Figure 19As shown, in some embodiments, the outlet 272 of the drainage pump 27 is located on the outer peripheral wall of the drainage pump 27. The outlet 272 extends laterally. An adapter 275 may be provided at the outlet 272. One end of the adapter 275 is connected to the outlet 272, and the other end of the adapter 275 can be connected to the water tank 3 through a pipeline. The end of the adapter 275 away from the outlet 272 may be higher than the highest water level line L2.
