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] In dehumidifiers, the water tray is usually equipped with a water filter. However, the space inside the water tray is limited, and the filtration area of ​​the water filter is small, which makes the mesh of the water filter easy to get clogged. Utility Model Content

[0005] The purpose of this invention is to provide a dehumidifier that solves the problem of the small area of ​​the water filter screen inside the water tray.

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

[0007] According to one aspect of this utility model, a dehumidifier is provided, comprising: a casing forming the outer shell of the dehumidifier; a receiving space provided inside the casing; a refrigeration system disposed within the receiving space, the refrigeration system including a compressor, a condenser, and an evaporator; a water collection box disposed below the evaporator, the water collection box being used to collect condensate; a water collection hole provided on the top surface of the water collection box; a water pumping area and a water flow channel provided inside the water collection box; one end of the water flow channel communicating with the water collection hole; and the other end of the water flow channel communicating with the water pumping area; wherein, the condensate flowing down from the evaporator can flow into the water flow channel through the water collection hole and flow along the water flow channel to the water pumping area; a first water filter screen is provided inside the water collection box, the first water filter screen being arranged obliquely from bottom to top within the water flow channel; water flowing through the water flow channel can pass through the first water filter screen, flowing from below the first water filter screen to above the first water filter screen, and then flowing to the water pumping area.

[0008] The above-mentioned technical solution has the following advantages or beneficial effects: After the water in the water flow channel is filtered by the first water filter screen before entering the pumping area, impurities such as mud, sand, and lint can be prevented from entering the pumping area, effectively preventing blockage of the drainage pump and extending its service life. By arranging the first water filter screen at an angle from bottom to top within the water flow channel, the contact area between the first water filter screen and the water in the channel can be increased. A larger first water filter screen can also be placed inside the water receiving box, improving the space utilization efficiency within the box and solving the problem of the small area of ​​the water filter screen inside the water receiving tray, thus mitigating the problem of easy clogging of the water filter screen's mesh.

[0009] In some embodiments of this application, the water flow channel includes a sedimentation zone; a first water filter screen is arranged obliquely from bottom to top in the sedimentation zone, and the first water filter screen divides the sedimentation zone into a lower space and an upper space; the lower space is located below the first water filter screen and communicates with the water inlet hole; the upper space is located above the first water filter screen and communicates with the pumping zone.

[0010] The above-mentioned technical solution has the following advantages or beneficial effects: When condensate enters the water receiving box through the water inlet and flows into the pumping area through the water flow channel, the water in the water flow channel can flow through the sedimentation zone. Heavier particles such as silt can gradually settle in the lower space. After flowing through the first water filter screen, impurities such as lint will also be blocked on the lower side of the first water filter screen and deposited in the lower space. This helps to improve the filtration efficiency of the first water filter screen, prevents the mesh of the water filter screen from clogging, and further improves the problem of easy clogging of the mesh of the water filter screen.

[0011] In some embodiments of this application, the dehumidifier includes: a base disposed within the housing, the base having a receiving cavity with an opening for taking out and putting in water, the opening being located on the outer side wall of the base; an evaporator disposed above the base; and a water collection box being slidably disposed within the receiving cavity from the opening for taking out and putting in water.

[0012] The above-mentioned technical solution has the following advantages or beneficial effects: the accommodating cavity in the base provides installation space for the water receiving box. When the water receiving box is pushed into the accommodating cavity, one side of the outer wall of the water receiving box can be exposed at the access port, making it easy to remove the water receiving box from the access port.

[0013] In some embodiments of this application, the water receiving box is exposed on the side wall of the inlet / outlet to form an outer panel; the outer panel is provided with a first insertion port, which communicates with the sedimentation zone; the first water filter screen is inserted into the sedimentation zone at an angle downward through the first insertion port.

[0014] The above-mentioned technical solution has the following advantages or beneficial effects: by setting the first insertion port on the outer panel, the first insertion port can be exposed at the take-up and take-down port of the base, thereby allowing the outer end of the first water filter screen to be exposed on the outer side wall of the base and the outer end of the first water filter screen to be exposed outside the casing, which makes it convenient for users to take out the first water filter screen and clean it separately, preventing the mesh of the first water filter screen from becoming clogged.

[0015] In some embodiments of this application, a first installation area is formed between the upper space and the lower space. The first installation area connects the upper space and the lower space. The first installation area extends obliquely toward the first insertion port, and the upper end of the first installation area is connected to the first insertion port. The first water filter screen is inserted obliquely downward into the first installation area from the first insertion port.

[0016] The above technical solution has the following advantages or beneficial effects: the first installation area can separate the upper space and the lower space, which makes it easier for the first water filter screen to be aligned and inserted into the first installation area, thereby enabling the first water filter screen to be stably and tilted in the water flow channel.

[0017] In some embodiments of this application, one end of the first water filter is exposed at the first insertion port, and the exposed end of the first water filter is provided with a handle groove, which is exposed at the outer panel.

[0018] The above-mentioned technical solution has the following advantages or beneficial effects: Through the handle groove at the outer end of the first water filter screen, the user can easily insert the first water filter screen into the water receiving box, or easily pull the first water filter screen out of the water receiving box.

[0020] The above-mentioned technical solution has the following advantages or beneficial effects: the sealing element allows users to easily open or close the drain outlet. When the drain outlet is opened, impurities such as mud, sand particles, and lint deposited in the lower space are discharged from the drain outlet into the water collection box, facilitating cleaning of the inside of the water collection box.

[0021] In some embodiments of this application, the water flow channel includes a secondary filtration zone located between the sedimentation zone and the pumping zone, and a second installation zone connects the secondary filtration zone and the pumping zone; the upper space is connected to the pumping zone through the secondary filtration zone, and a second water filter screen is provided at the connection between the secondary filtration zone and the pumping zone.

[0022] The above technical solution has the following advantages or beneficial effects: the water filtered by the first water filter can flow to the secondary filtration zone, and after being filtered by the second water filter, it enters the pumping zone, further preventing impurities such as lint from entering the pumping zone.

[0023] In some embodiments of this application, a second insertion port is provided on the top surface of the water receiving box; an isolation wall is provided between the secondary filtration zone and the pumping zone, and a second installation zone is provided on the isolation wall; the second insertion port and the second installation zone are arranged vertically opposite to each other and are connected; the second water filter screen is inserted downward into the second installation zone through the second insertion port.

[0024] The above-mentioned technical solution has the following advantages or beneficial effects: The isolation wall can spatially separate the second installation area and the pumping area, facilitating the alignment and insertion of the second water filter screen into the second installation area, thereby enabling the second water filter screen to be stably and vertically arranged between the second installation area and the pumping area. Furthermore, through the second insertion port on the top surface of the water receiving box, the user can easily insert the second water filter screen into the water receiving box, or remove the second water filter screen from the water receiving box.

[0025] In some embodiments of this application, the water flow channel may include a water receiving area and a curved channel. The water receiving area is located below the water receiving hole. One end of the curved channel communicates with the water receiving area, and the other end of the curved channel communicates with the lower space.

[0026] The above-mentioned technical solution has the following advantages or beneficial effects: condensate water enters the water receiving box through the water inlet, first entering the water receiving area, then flowing through the curved channel towards the lower space of the sedimentation area. Heavier particles such as silt can gradually settle in the curved channel and the lower space, preventing the water filter screen from becoming clogged. Attached Figure Description

[0060] Figure 1 This is a structural diagram of a dehumidifier according to some embodiments of the present invention. Figure 2 yes Figure 1 A decomposed structure diagram.

[0061] like Figure 1 and Figure 2 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.

[0062] 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.

[0063] like Figure 1 and Figure 2As 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.

[0065] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the dehumidifier includes a dehumidification device disposed within the casing 1. The dehumidification device can be a refrigeration system 20. The refrigeration system 20 can be disposed within the casing 1. The refrigeration system 20 includes a compressor 21, a condenser 22, and an evaporator 23. The compressor 21, condenser 22, and evaporator 23 are connected end-to-end to form a refrigerant circulation loop. 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 and 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.

[0066] 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.

[0067] It should be noted that in other embodiments, the dehumidification device may also employ other types of dehumidification systems as needed.

[0068] like Figure 3 and Figure 4As shown, in some embodiments, the housing 1 has a receiving space 10. The refrigeration system 20 may be located within the receiving space 10. The compressor 21, condenser 22, and evaporator 23 may each be located within the receiving space 10.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments, the receiving space 10 may be located in the lower space inside the housing 1. Thus, the compressor 21, condenser 22, and evaporator 23 may each be located in the lower space inside the housing 1.

[0070] like Figure 1 and Figure 3 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.

[0071] like Figure 1 As 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. In addition, the air inlet grille 1011 can block the air inlet 101 to prevent foreign objects from entering the air inlet 101 and coming into contact with the evaporator 23, which helps to improve the safety and stability of the dehumidifier.

[0072] Figure 6 yes Figure 5 A sectional view.

[0073] like Figure 2 , Figure 3 and Figure 6 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 arranged side by side with the evaporator 23. 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.

[0074] like Figure 2 and Figure 3As 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.

[0075] like Figure 3 , Figure 5 and Figure 6 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 air 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.

[0076] like Figure 2 and Figure 3 As 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.

[0077] like Figure 5 and Figure 6 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.

[0078] 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.

[0079] In some embodiments, the duct housing 241 may be a volute structure. The impeller 242 may be a turbine structure.

[0080] 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.

[0081] Figure 7 yes Figure 5 A decomposed structure diagram.

[0082] like Figure 5 , Figure 6 and Figure 7 As 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. An air intake 2411 may be formed on the side wall of the fan shroud 244 facing the impeller 242. The side of the air cavity 2441 near the duct housing 241 communicates with the interior of the duct housing 241 through the air intake 2411, and the condenser 22 is disposed on the other side of the air cavity 2441. 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 condenser 22 may be disposed at the opening of the air cavity 2441. 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.

[0083] In some embodiments, the opening of the air cavity 2441 can be consistent with the outline of the condenser 22, the outline of the evaporator 23, and the outline of the air inlet 101, so that the air entering the air inlet 101 can fully contact the evaporator 23 and the condenser 22, and then enter the air duct shell 241 through the air cavity 2441 and the air intake 2411, thereby improving the air intake efficiency.

[0084] It should be noted that in some other embodiments, the outlines of the condenser 22, the evaporator 23, and the air inlet 101 may also be larger than the opening of the air cavity 2441.

[0085] like Figure 6 and Figure 7 As shown, in some embodiments, the dehumidifier includes a water collection box 25 for collecting condensate. The water collection box 25 may be located inside the housing 1. The water collection box 25 may be located below the evaporator 23. The evaporator 23 may be located above the water collection box 25. The condenser 22 may be located above the water collection box 25. The water collection box 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 water collection box 25.

[0086] Figure 8 yes Figure 7 A partial decomposition diagram of the middle part of the structure.

[0087] like Figure 5 , Figure 7 and Figure 8 As shown, in some embodiments, the dehumidifier includes a base 15. The base 15 may be located in the bottom region within the housing 1. A receiving space 10 may be formed in the space above the base 15. The compressor 21, condenser 22, evaporator 23, and fan assembly 24 may be respectively mounted above the base 15. The base 15 provides mounting space for components such as the compressor 21, condenser 22, evaporator 23, and fan assembly 24, allowing the compressor 21, condenser 22, evaporator 23, and fan assembly 24 to be supported on the base 15 respectively.

[0088] like Figure 7 and Figure 8 As shown, in some embodiments, the water collection box 25 can be slidably disposed within the housing 1. The water collection box 25 can also be slidably disposed within the base 15. The base 15 may be provided with a drain outlet 151. A water collection hole 2511 may be provided on the top surface of the water collection box 25. The water collection hole 2511 communicates with the interior of the water collection box 25. The drain outlet 151 and the water collection hole 2511 are arranged vertically opposite each other. The condensate generated on the evaporator 23 can flow down the outer wall of the evaporator 23 to the base 15, and then flow into the interior of the water collection box 25 through the drain outlet 151 and the water collection hole 2511. The condensate collects in the water collection box 25 and is stored within it.

[0089] It should be noted that in some other embodiments, the water receiving box 25 may also be located on the top surface of the base 15. In this case, the condenser 22 and the evaporator 23 may be supported above the water receiving box 25.

[0090] like Figure 5 and Figure 7 As shown, in some embodiments, the compressor 21 is located on the same side as the fan assembly 24, the condenser 22, and the evaporator 23. The fan assembly 24, the condenser 22, and the evaporator 23 can be located on one side above the base 15, and the compressor 21 can be located on the other side above the base 15, thereby making full use of the space above the base 15 and improving the space utilization efficiency of the accommodating space 10.

[0091] like Figure 7 and Figure 8 As shown, in some embodiments, the dehumidifier includes a drain pump 27, which is used to draw water from the water collection box 25 and discharge it. The drain pump 27 may be disposed in the receiving space 10 within the housing 1. The suction end of the drain pump 27 communicates with the interior of the water collection box 25, and the drain pump 27 can be used to draw water from the water collection box 25 and discharge the drawn water from the water collection box 25.

[0092] like Figure 8 As shown, in some embodiments, the drain pump 27 can be located inside the fan housing 244. The drain pump 27 can be located on the inner wall of the fan housing 244, providing installation space for it. Alternatively, the drain pump 27 can be located on the cavity wall of the air chamber 2441. By arranging the drain pump 27 on the cavity wall of the air chamber 2441, the drain pump 27 does not occupy external space of the fan assembly 24 and does not require additional space within the housing space 10, thus improving the space utilization efficiency within the dehumidifier. When the fan assembly 24 is running, indoor air can enter the casing 1 through the air inlet, flow sequentially through the evaporator 23 and condenser 22, and then enter the fan assembly 24 through the air chamber 2441; the air flowing through the air chamber 2441 can dissipate heat from the surface of the drain pump 27. Furthermore, the large space within the air chamber 2441 facilitates the installation of the drain pump 27 and the connection between the drain pump 27 and the piping.

[0093] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the dehumidifier includes a water tank 3 for collecting condensate. The water tank 3 may be located in the top area inside the casing 1. The water tank 3 may be located above the receiving 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 water collection box 25. The drain pump 27 can draw water from the water collection box 25 and drain the water 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.

[0094] 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.

[0095] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a receiving cavity 40 is provided in the top region of the housing 1. The receiving cavity 40 can extend downward from the top surface of the housing 1. The water tank 3 can be installed in the receiving cavity 40 from top to bottom. The receiving cavity 40 can be located above the receiving space 10, and the receiving space 10 can be located below the receiving cavity 40. The receiving cavity 40 can be located in the upper region of the housing 1, and the receiving space 10 can be located in the lower region of the housing 1, so that the housing 1 forms an upper and lower two-layer structure. When the water tank 3 is installed in the receiving cavity 40 of the housing 1 from top to bottom, the top surface of the water tank 3 can be exposed on the top surface of the housing 1, and the side wall of the water tank 3 can be hidden in the receiving cavity 40. The water tank 3 is arranged in the upper receiving cavity 40 inside the casing 1, while the compressor 21, condenser 22, evaporator 23, fan assembly 24, etc. are arranged in the lower receiving space 10 inside the casing 1. This arrangement can make full use of the upper space inside the casing 1 and is beneficial to increasing the effective volume inside the water tank 3.

[0096] like Figure 1 and Figure 2 As shown, in some embodiments, the dehumidifier may include a control panel 14, which may be located on the top surface of the housing 1. The control panel 14 may have multiple buttons and can be used by the user to control operations such as turning the dehumidifier on or off. A receiving cavity 40 may be formed on one side of the control panel 14. When the water tank 3 is installed inside the receiving cavity 40, the water tank 3 may be arranged on one side of the control panel 14.

[0097] Figure 9 yes Figure 2 Structural diagram of inner liner 4.

[0098] like Figure 2 , Figure 3 and Figure 9 As shown, in some embodiments, the dehumidifier may include 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 receiving space 10 may be formed in the space between the bottom of the inner liner 4 and the top of the base 15. A receiving cavity 40 may be formed inside the inner liner 4. The top of the inner liner 4 may extend to the top surface of the housing 1, thereby allowing the top of the receiving cavity 40 to extend upward to the top surface of the housing 1. When the water tank 3 is installed in the receiving cavity 40, the top surface of the water tank 3 may be exposed above the top surface of the housing 1.

[0099] like Figure 3 and Figure 4 As shown, in some embodiments, the top of the fan assembly 24 can abut against the bottom surface of the inner liner 4. The top of the evaporator 23 can abut against the bottom surface of the inner liner 4. The top of the condenser 22 can abut against the bottom surface of the inner liner 4. Thus, by having the tops of the fan assembly 24, condenser 22, and evaporator 23 abut against the bottom surface of the inner liner 4 respectively, the bottom of the inner liner 4 can be supported on the tops of the fan assembly 24, evaporator 23, and condenser 22 respectively, improving the structural strength of the inner liner 4 and enhancing the structural stability of the water tank 3 within the casing 1. Furthermore, by arranging the water tank 3 within the upper inner liner 4 within the casing 1, and the compressor 21, condenser 22, evaporator 23, fan assembly 24, etc., within the receiving space 10 below the inner liner 4, the upper space within the casing 1 can be fully utilized, increasing the volume of the receiving cavity 40 and thereby increasing the effective volume within the water tank 3.

[0100] like Figure 3 and Figure 4 As shown, in some embodiments, the fan assembly 24, condenser 22, and evaporator 23 can be located below the receiving cavity 40, that is, the tops of the fan assembly 24, condenser 22, and evaporator 23 can be supported on the bottom surface of the inner liner 4 below the receiving cavity 40. Therefore, when the water tank 3 is placed inside the receiving cavity 40, most of the weight of the water tank 3 can be transferred downwards to the top surfaces of the fan assembly 24, condenser 22, and evaporator 23, improving the stability of the water tank 3 within the casing 1 and increasing the load-bearing capacity of the inner liner 4.

[0101] Figure 10 yes Figure 9 A structural diagram from another perspective.

[0102] like Figure 3 , Figure 9 and Figure 10 As shown, in some embodiments, a control section 41 is formed on one side of the inner liner 4. A receiving cavity 40 may be formed on one side of the control section 41. A control panel 14 may be disposed on the top of the control section 41, and the control panel 14 may be exposed on the top surface of the housing 1. The top of the control section 41 can provide installation space for the control panel 14, allowing the control panel 14 to be located on the top surface of the housing 1 and to be kept away from the water tank 3, thus preventing the control panel 14 from contacting the water in the water tank 3.

[0103] like Figure 9 and Figure 10 As shown, in some embodiments, a display panel (not shown) may be provided below the control panel 14. The display panel may be fixed to the bottom surface of the control panel 14. The display panel can be used for display and control. Users can also control the display panel through the control panel 14, thereby generating control signals to control the operation of the internal components of the dehumidifier.

[0104] like Figure 3 , Figure 9 and Figure 10 As shown, in some embodiments, a mounting cavity 410 may be formed on the side of the control unit 41 away from the receiving cavity 40. The mounting cavity 410 may be located above the receiving space 10. The dehumidifier may include an electrical control box assembly 5. The electrical control box assembly 5 may be disposed within the mounting cavity 410. The mounting cavity 410 within the control unit 41 may be used to provide mounting space for the electrical control box assembly 5. The control panel 14 may be disposed above the top of the mounting cavity 410. The control unit 41 may isolate the water tank 3 from the electrical control box assembly 5, preventing the electrical control box assembly 5 from contacting the water in the water tank 3. Furthermore, the electrical control box assembly 5 may be disposed above the receiving space 10, so that the electrical control box assembly 5 can avoid contact with the evaporator 23, condenser 22, etc., preventing condensate from the surface of the evaporator 23 or condenser 22 from entering the electrical control box assembly 5.

[0105] like Figure 2 and Figure 9As shown, in some embodiments, the peripheral sidewall of the inner liner 4 may be provided with a surrounding plate 42. The surrounding plate 42 may be arranged around the periphery of the receiving cavity 40. The top of the surrounding plate 42 may extend to the top of the control unit 41. The receiving cavity 40 may be enclosed between the surrounding plate 42 and the sidewall of the control unit 41. For example, the receiving cavity 40 may be a cavity structure with a square outline. The surrounding plate 42 may encircle three sidewalls of the receiving cavity 40 with a square outline, and the sidewall of the control unit 41 facing the receiving cavity 40 may form a fourth sidewall of the receiving cavity 40 with a square outline. The peripheral sidewall of the water tank 3 may be hidden inside the control unit 41 and the surrounding plate 42. The surrounding plate 42 may be arranged along the inner side of the peripheral sidewall of the housing 1. With the internal space of the housing 1 unchanged, by arranging the surrounding plate 42 close to the inner sidewall of the housing 1, the volume of the water tank 3 can be effectively increased, thereby increasing the effective internal volume of the water tank 3.

[0106] like Figure 2 and Figure 9 As shown, in some embodiments, a nozzle 43 may be provided on the side wall of the control unit 41 facing the receiving cavity 40, and the nozzle 43 is arranged facing the receiving cavity 40. The outlet end of the drain pump 27 may be provided with a drain pipe 273, the upper end of the drain pipe 273 extending upward to the nozzle 43 and communicating with the nozzle 43, so that the outlet end of the drain pump 27 can communicate with the nozzle 43. When the water tank 3 is placed in the receiving cavity 40, the nozzle 43 can be arranged facing the inside of the water tank 3. After the drain pump 27 draws water from the water receiving box 25, it can spray the water into the inside of the water tank 3 through the drain pipe 273 and the nozzle 43, and collect it in the water tank 3.

[0107] It should be noted that in other embodiments, the nozzle 43 may also be located on other side walls of the receiving cavity 40.

[0108] like Figure 2 and Figure 9 As shown, in some embodiments, the nozzle 43 is disposed in the side wall of the receiving cavity 40, and the nozzle 43 does not extend beyond the side wall of the receiving cavity 40. Therefore, when the water tank 3 is placed into the receiving cavity 40 from top to bottom, the nozzle 43 will not interfere with the water tank 3 and will not hinder the water tank 3 from being placed into the receiving cavity 40 from top to bottom.

[0109] like Figure 3 and Figure 4 As shown, in some embodiments, the dehumidifier includes a support rod 16 disposed within the housing 1. The support rod 16 can extend along the height direction of the housing 1. The top end of the support rod 16 can be connected to the inner liner 4, and the bottom end of the support rod 16 can be connected to the base 15. The support rod 16 can support the inner liner 4 between the inner liner 4 and the base 15, improving the stability of the inner liner 4 within the housing 1. Furthermore, the support rod 16 can cooperate with the tops of the fan assembly 24, the condenser 22, and the evaporator 23 to jointly support the inner liner 4, improving the structural stability and load-bearing capacity of the inner liner 4.

[0110] like Figure 3 and Figure 4 As shown, in some embodiments, the support rod 16 may be located below the control unit 41. The support rod 16 may be spaced apart on one side of the fan assembly 24, condenser 22, and evaporator 23. The top end of the support rod 16 is connected to the control unit 41, and the bottom end of the support rod 16 is connected to the base 15. The support rod 16 can be supported between the control unit 41 and the base 15, improving the structural stability of the control unit 41, allowing the control unit 41 and the mounting cavity 410 to be suspended above the receiving space 10; in conjunction with the bottom of the inner liner 4 below the receiving cavity 40 being supported on the top of the fan assembly 24, condenser 22, and evaporator 23, the structural stability and load-bearing capacity of the inner liner 4 can be further improved.

[0111] like Figure 4 As shown, in some embodiments, the top end of the support rod 16 can extend into the mounting cavity 410 and be arranged on one side of the electrical control box assembly 5. The mounting cavity 410 can provide mounting space for the top end of the support rod 16 and the electrical control box assembly 5 respectively; the top end of the support rod 16 extending into the mounting cavity 410 and being supported on the control unit 41 can improve the structural stability of the mounting cavity 410.

[0112] like Figure 4 As shown, in some embodiments, a cable tray 160 is provided inside the support rod 16. The cable tray 160 can extend along the length direction of the support rod 16, and the cable tray 160 can extend along the height direction of the housing 1. The wire harness inside the housing 1 can be gathered in the cable tray 160, improving the space utilization rate inside the housing 1.

[0113] like Figure 4 As shown, in some embodiments, the upper end of the wiring trough 160 can communicate with the mounting cavity 410. The lower end of the wiring trough 160 communicates with the accommodating space 10. The wire harnesses in the mounting cavity 410 can be neatly arranged in the wiring trough 160 of the support rod 16, and the wire harnesses in the accommodating space 10 can also be neatly arranged in the wiring trough 160 of the support rod 16. Furthermore, the wire harnesses in the accommodating space 10 can enter the mounting cavity 410 through the wiring trough 160, which facilitates cable management and improves the space utilization rate of the accommodating space 10 and the mounting cavity 410.

[0114] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the support rod 16 can be located at the peripheral edge of the base 15 and the inner liner 4. The support rod 16 can be arranged close to the inner wall of the housing 1, thereby reducing the space occupied by the support rod 16 inside the housing 1. The wiring trough 160 is open facing the corresponding inner wall of the housing 1, which facilitates the wiring harness to be arranged in the wiring trough 160 from the open opening. After the housing 1 is assembled, the inner sidewall of the housing 1 can cover the open opening of the wiring trough 160, encapsulating the wiring harness in the wiring trough 160 of the support rod 16, preventing the wiring harness from coming out of the wiring trough 160.

[0115] like Figure 3 and Figure 4 As shown, in some embodiments, the lower end of the support rod 16 can be located in a corner area of ​​the base 15, and the upper end of the support rod 16 can be located in the corresponding corner area of ​​the inner liner 4. By placing the upper end and the lower end of the support rod 16 in the corner areas of the inner liner 4 and the base 15 respectively, the space occupied by the support rod 16 in the internal space of the housing 1 can be further reduced.

[0116] like Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, a fixing groove 152 is provided in the corner area of ​​the top surface of the base 15, and the fixing groove 152 can be recessed into the top surface of the base 15. The lower end of the support rod 16 is inserted into the fixing groove 152. By engaging the fixing groove 152 with the lower end of the support rod 16, the lower end of the support rod 16 can be fixed to the base 15, thereby improving the structural stability of the support rod 16.

[0117] like Figure 2 and Figure 3 As shown, in some embodiments, the top of the housing 1 can cover the outer peripheral wall of the inner liner 4, and the bottom of the housing 1 can cover the outer peripheral wall of the base 15, thereby improving the flatness of the dehumidifier's appearance and forming the accommodating space 10 between the bottom of the inner liner 4, the top of the base 15, and the inner wall of the housing 1, thus improving the structural stability between the inner liner 4 and the base 15, and improving the structural stability of the accommodating space 10.

[0118] Figure 11 yes Figure 7 Partial structural diagram of the middle part. Figure 12 yes Figure 11 A decomposed structure diagram.

[0119] like Figure 11 and Figure 12As shown, in some embodiments, the base 15 may have a receiving cavity 150. The receiving cavity 150 has a pick-and-place opening 1501, which is located on the outer side wall of the base 15. The water receiving box 25 can be pushed and pulled into the receiving cavity 150 through the pick-and-place opening 1501. The receiving cavity 150 provides installation space for the water receiving box 25. When the water receiving box 25 is pushed into the receiving cavity 150, one side of the outer wall of the water receiving box 25 can be exposed at the pick-and-place opening 1501, making it easy for the water receiving box 25 to be removed from the pick-and-place opening 1501.

[0120] like Figure 11 and Figure 12 As shown, in some embodiments, the water receiving box 25 can form an outer panel 2521 on the side wall exposed outside the dispensing port 1501. When the water receiving box 25 is pushed into the receiving cavity 150, the outer panel 2521 can close the dispensing port 1501. When the water receiving box 25 is pushed into the receiving cavity 150, the outer panel 2521 can be exposed on the outer side wall of the base 15, making it convenient for the user to push and pull the water receiving box 25 through the outer panel 2521.

[0121] like Figure 1 and Figure 11 As shown, in some embodiments, the outer panel 2521 may be exposed on the outer side wall of the housing 1, thereby facilitating the user to take the water box 25 out from the outside of the housing 1, push the water box 25 into the receiving cavity 150, or pull the water box 25 out from the receiving cavity 150.

[0122] like Figure 11 and Figure 12 As shown, in some embodiments, a handle groove 2522 may be provided on the outer side wall of the outer panel 2521. Through the handle groove 2522 on the outer panel 2521, the user can easily push the water receiving box 25 into the receiving cavity 150, or easily pull the water receiving box 25 out of the receiving cavity 150.

[0123] Figure 13 yes Figure 12 A structural diagram from another perspective.

[0124] like Figure 12 and Figure 13 As shown, in some embodiments, the receiving cavity 150 may have a bottom opening 1502. The bottom opening 1502 may be located on the bottom surface of the base 15. When the water receiving box 25 is pushed into the receiving cavity 150 through the inlet 1501, the bottom surface of the water receiving box 25 may be exposed at the bottom opening 1502, or extend out of the bottom opening 1502 of the receiving cavity 150 and be disposed downward in the space below the bottom surface of the base 15.

[0125] like Figure 12 and Figure 13As shown, in some embodiments, a micro switch 154 may be provided inside the base 15. The micro switch 154 may be located at the top of the receiving cavity 150. A float switch 253 is provided inside the water receiving box 25, and the float switch 253 is exposed on the top surface of the water receiving box 25; the micro switch 154 and the float switch 253 are arranged vertically opposite each other. When the water receiving box 25 is pushed into the receiving cavity 150, the float switch 253 can abut against the micro switch 154, thereby confirming that the water receiving box 25 has been pushed into place. By placing the micro switch 154 at the top of the receiving cavity 150, contact between the micro switch 154 and the water in the water receiving box 25 can be avoided or reduced, thus preventing corrosion or damage to the micro switch 154.

[0126] When the water level in the water collection box 25 rises to a certain height, the float switch 253 can disengage from the micro switch 154, generating a corresponding control signal to control the drain pump 27 to drain water or remind the user to remove the water collection box 25 to empty it. For example, the float switch 253 is rotatably mounted inside the water collection box 25. When the water level in the water collection box 25 rises to a certain height, the float switch 253 rotates, thereby disengaging from the micro switch 154.

[0127] Figure 14 yes Figure 11 A sectional view.

[0128] like Figure 11 and Figure 14 As shown, in some embodiments, the drain pump 27 can be arranged above the base 15. The drain pump 27 can be arranged above the water receiving box 25. The suction end of the drain pump 27 can be provided with a suction pipe 274, which can extend downward into the base 15. The lower end of the suction pipe 274 can extend into the receiving cavity 150. When the water receiving box 25 is pushed into the receiving cavity 150, the lower end of the suction pipe 274 can extend into the receiving box 25. By having the suction pipe 274 pass through the base 15, the suction pipe 274 can be fixed in the base 15 and suspended in the receiving cavity 150, facilitating the insertion of the suction pipe 274 into the receiving box 25, thus achieving the connection between the suction pipe 274 and the receiving box 25, and facilitating the pump to draw water from the receiving box 25 and discharge it through the suction pipe 274.

[0129] Figure 15 yes Figure 14 A decomposed structure diagram. Figure 16 yes Figure 12 Side view of the water receiving box 25.

[0130] like Figure 15 and Figure 16As shown, in some embodiments, a first groove 155 may be provided on the side wall of the receiving cavity 150. A first sliding part 2501 may be provided on the outer wall of the water receiving box 25. The first sliding part 2501 is used to slide along the first groove 155. Through the sliding engagement of the first sliding part 2501 and the first groove 155, the water receiving box 25 can slide along the first groove 155 through the first sliding part 2501 inside the receiving cavity 150, and be smoothly pushed into or pulled out of the receiving cavity 150, and thus smoothly pushed into or pulled out of the base 15.

[0131] like Figure 13 As shown, in some embodiments, two first sliding grooves 155 may be provided, with the two first sliding grooves 155 respectively disposed on opposite side walls of the receiving cavity 150. Two first sliding parts 2501 may be provided, with the two first sliding parts 2501 respectively disposed on opposite side outer walls of the water receiving box 25. The two first sliding parts 2501 may be arranged corresponding to the two first sliding grooves 155 to improve the stability of the water receiving box 25 when pushed and pulled.

[0132] Figure 17 yes Figure 15 A structural diagram of the water inlet box 25 being pushed into the receiving cavity 150. Figure 18 yes Figure 17 A structural diagram showing the water inlet box 25 being pushed further into the receiving cavity 150.

[0133] like Figure 16 , Figure 17 and Figure 18 As shown, in some embodiments, the first chute 155 may include a first straight section 1551. The first straight section 1551 may extend linearly on the side wall of the receiving cavity 150. One end of the first straight section 1551 extends outward to the dispensing port 1501, and the other end of the first straight section 1551 extends towards the interior of the receiving cavity 150. When the water receiving box 25 is pushed into the receiving cavity 150 from the dispensing port 1501, the first sliding part 2501 can extend from the dispensing port 1501 into the first straight section 1551 and move along the first straight section 1551 into the receiving cavity 150, thereby allowing the water receiving box 25 to be smoothly pushed into the receiving cavity 150.

[0134] Figure 19 yes Figure 18 A structural diagram showing the water inlet box 25 being pushed further into the receiving cavity 150. Figure 20 yes Figure 19 A structural diagram showing the water inlet box 25 being pushed further into the receiving cavity 150.

[0135] like Figure 16 , Figure 19 and Figure 20As shown, in some embodiments, the first chute 155 may include a first lifting section 1552. The first lifting section 1552 extends obliquely on the side wall of the receiving cavity 150. The first lifting section 1552 extends from the inner end of the first straight section 1551 toward the interior of the receiving cavity 150, and extends toward the top side wall of the receiving cavity 150. That is, the first lifting section 1552 may extend obliquely upward toward the interior of the receiving cavity 150. The first sliding part 2501 may slide from the first straight section 1551 into the first lifting section 1552, and move along the first lifting section 1552 toward the interior of the receiving cavity 150, thereby gradually bringing the water receiving box 25 closer to the top side wall of the receiving cavity 150, and thus gradually reducing the distance between the water receiving box 25 and the top side wall of the receiving cavity 150. As the distance between the water receiving box 25 and the top sidewall of the receiving cavity 150 decreases, the lower end of the suction pipe 274 can gradually extend into the water receiving box 25, thus connecting the water receiving box 25 and the suction pipe 274. Furthermore, as the distance between the water receiving box 25 and the top sidewall of the receiving cavity 150 decreases, the float switch 253 on the top surface of the water receiving box 25 can gradually contact and abut against the micro switch 154, thereby confirming that the water receiving box 25 has been pushed into place.

[0136] Figure 21 yes Figure 20 A structural diagram showing the water inlet box 25 being pushed further into the receiving cavity 150.

[0137] like Figure 16 , Figure 20 and Figure 21As shown, in some embodiments, the first slide 155 may include a second straight section 1553. The second straight section 1553 may extend linearly on the side wall of the receiving cavity 150. The second straight section 1553 may be spaced apart inside the first straight section 1551, that is, the second straight section 1553 may be spaced apart on the side of the first straight section 1551 away from the pick-up / drop-off port 1501. The second straight section 1553 may be located on the side of the first straight section 1551 near the top wall of the receiving cavity 150. The first lifting section 1552 may extend obliquely from the inner end of the first straight section 1551 to the outer end of the second straight section 1553. The second straight section 1553 may extend from the inner end of the first lifting section 1552 toward the interior of the receiving cavity 150. The first lifting section 1552 and the first straight section 1551 may be smoothly connected. The first lifting section 1552 and the second straight section 1553 can be smoothly connected. The first sliding part 2501 can slide from the first lifting section 1552 into the second straight section 1553, and move along the second straight section 1553 into the receiving cavity 150, so as to maintain the distance between the top and side walls of the receiving box 25 and allow the receiving box 25 to be placed stably in the receiving cavity 150.

[0138] like Figure 14 and Figure 15 As shown, during the process of pushing the water receiving box 25 into the receiving cavity 150, the first sliding part 2501 can slide into the receiving cavity 150 sequentially along the first straight section 1551, the first lifting section 1552, and the second straight section 1553. When the first sliding part 2501 slides inward along the first straight section 1551, the water receiving box 25 can maintain a sufficient distance from the top side wall of the receiving cavity 150, reducing interference with the water suction pipe 274 on the top side wall of the receiving cavity 150 and avoiding collision with the micro switch 154 on the top side wall of the receiving cavity 150, so that the water receiving box 25 can move smoothly into the receiving cavity 150. When the first sliding part 2501 slides inward along the first lifting section 1552, the height of the water receiving box 25 can be gradually increased, and the distance between the water receiving box 25 and the top side wall of the accommodating cavity 150 can be gradually reduced, so that the water suction pipe 274 can be gradually inserted into the water receiving box 25, and the float switch 253 on the top surface of the water receiving box 25 can gradually move upward to contact and abut against the micro switch 154 on the top side wall of the accommodating cavity 150. When the first sliding part 2501 slides inward along the second straight section 1553, it can smoothly maintain a small distance between the water receiving box 25 and the top side wall of the accommodating cavity 150, maintain the distance between the bottom end of the water suction pipe 274 and the inner bottom surface of the water receiving box 25, and maintain the contact state between the micro switch 154 and the float switch 253, thereby improving the smoothness and stability of the water receiving box 25 during the pushing process, avoiding affecting the normal operation of devices such as the water suction pipe 274 and the micro switch 154, and solving the collision problem when the water receiving box 25 is placed into the dehumidifier.

[0139] like Figure 14 and Figure 15 As shown, during the process of pulling the water receiving box 25 out of the accommodating cavity 150, the first sliding part 2501 can slide out of the accommodating cavity 150 sequentially along the second straight section 1553, the first lifting section 1552, and the first straight section 1551. When the first sliding part 2501 slides outward along the first lifting section 1552, the height of the water receiving box 25 can be gradually reduced, and the distance between the water receiving box 25 and the top side wall of the accommodating cavity 150 can be gradually increased, so that the water suction pipe 274 gradually exits the interior of the water receiving box 25, and the float switch 253 on the top surface of the water receiving box 25 can gradually separate downward from the micro switch 154 on the top side wall of the accommodating cavity 150. When the first sliding part 2501 slides outward along the first straight section 1551, the water receiving box 25 can maintain a sufficient distance from the top side wall of the accommodating cavity 150, reducing interference with the water suction pipe 274 on the top side wall of the accommodating cavity 150 and avoiding collision with the micro switch 154 on the top side wall of the accommodating cavity 150. This allows the water receiving box 25 to move smoothly out of the accommodating cavity 150 until it is completely out of the take-out port 1501, thereby improving the smoothness and stability of the pull-out process of the water receiving box 25, avoiding affecting the normal operation of devices such as the water suction pipe 274 and the micro switch 154, and solving the collision problem when the water receiving box 25 is taken out of the dehumidifier.

[0140] It should be noted that, through the segmented structural design of the first straight section 1551, the first lifting section 1552, and the second straight section 1553 of the first slide 155, the dehumidifier can maintain long-term stable operation during the repeated use of the water receiving box 25. It also facilitates the periodic removal and cleaning of the water receiving box 25, avoiding problems such as water pump system failure and micro switch 154 malfunction after cleaning the water receiving box 25, thus helping to extend the service life of the dehumidifier.

[0141] like Figure 15 and Figure 16 As shown, in some embodiments, a second groove 156 may be provided on the side wall of the receiving cavity 150. A second sliding part 2502 may be provided on the outer wall of the water receiving box 25. The second sliding part 2502 is used to slide along the second groove 156. Through the sliding engagement of the second sliding part 2502 and the second groove 156, the water receiving box 25 can slide along the second groove 156 through the second sliding part 2502 inside the receiving cavity 150, and be smoothly pushed into or pulled out of the receiving cavity 150, thereby smoothly pushing into or pulling out of the base 15.

[0142] like Figure 13As shown, in some embodiments, two second sliding grooves 156 may be provided, with the two second sliding grooves 156 respectively disposed on opposite side walls of the receiving cavity 150. Two second sliding parts 2502 may be provided, with the two second sliding parts 2502 respectively disposed on opposite side outer walls of the water receiving box 25. The two second sliding parts 2502 may be arranged corresponding to the two second sliding grooves 156 to improve the stability of the water receiving box 25 when pushed and pulled.

[0143] like Figure 15 and Figure 16 As shown, in some embodiments, the first sliding portion 2501 and the second sliding portion 2502 are spaced apart along the pushing and pulling direction of the water receiving box 25. The second sliding portion 2502 is spaced apart on the side of the first sliding portion 2501 near the dispensing port 1501. The second sliding portion 2502 may be spaced apart on the side of the first sliding portion 2501 near the outer panel 2521. During the process of pushing the water receiving box 25 into the receiving cavity 150, the first sliding portion 2501 can enter the receiving cavity 150 before the second sliding portion 2502. Specifically, the first sliding portion 2501 first enters the first sliding groove 155 and slides inward a certain distance, and then the second sliding portion 2502 enters the second sliding groove 156 and slides inward, such as... Figure 18 As shown in the diagram, by having the first sliding part 2501 and the second sliding part 2502 enter the corresponding sliding grooves in sequence, the smoothness of the sliding of the water receiving box 25 can be improved, preventing the water receiving box 25 from tipping over to the side.

[0144] like Figure 15 , Figure 18 and Figure 19 As shown, in some embodiments, the second slide 156 may be located on the side of the first slide 155 near the top wall of the receiving cavity 150. The height of the second slide 156 may be higher than that of the first slide 155. Correspondingly, the second sliding part 2502 may be located above the first sliding part 2501, and the height of the second sliding part 2502 may be higher than that of the first sliding part 2501. When the first sliding part 2501 slides in the first slide 155 and the second sliding part 2502 slides in the second slide 156, the support point of the second sliding part 2502 is located above the support point of the first sliding part 2501, thereby making it more difficult for the water receiving box 25 to tip over to one side of the outer panel 2521, which can further improve the stability of the sliding of the water receiving box 25 and prevent the water receiving box 25 from tipping over to the side.

[0145] like Figure 16 , Figure 18 and Figure 19As shown, in some embodiments, the second slide 156 may include a third straight section 1561. The third straight section 1561 may be arranged in a straight line on the side wall of the receiving cavity 150. One end of the third straight section 1561 extends outward to the dispensing port 1501, and the other end of the third straight section 1561 extends towards the interior of the receiving cavity 150. When the water receiving box 25 is pushed into the receiving cavity 150 from the dispensing port 1501, the second sliding part 2502 can extend from the dispensing port 1501 into the third straight section 1561 and move along the third straight section 1561 into the receiving cavity 150, thereby allowing the water receiving box 25 to be smoothly pushed into the receiving cavity 150.

[0146] like Figure 16 , Figure 19 and Figure 20 As shown, in some embodiments, the second chute 156 may include a second lifting section 1562. The second lifting section 1562 extends obliquely on the sidewall of the receiving cavity 150. The second lifting section 1562 extends from the inner end of the third straight section 1561 toward the interior of the receiving cavity 150, and extends toward the top sidewall of the receiving cavity 150. That is, the second lifting section 1562 can extend obliquely upward toward the interior of the receiving cavity 150. The second sliding part 2502 can slide from the third straight section 1561 into the second lifting section 1562, and move along the second lifting section 1562 toward the interior of the receiving cavity 150, thereby gradually bringing the water receiving box 25 closer to the top sidewall of the receiving cavity 150, and thus gradually reducing the distance between the water receiving box 25 and the top sidewall of the receiving cavity 150.

[0147] like Figure 16 , Figure 20 and Figure 21 As shown, in some embodiments, the second slide 156 may include a fourth straight section 1563. The fourth straight section 1563 may extend linearly on the side wall of the receiving cavity 150. The fourth straight section 1563 may be spaced apart inside the third straight section 1561, that is, the fourth straight section 1563 may be spaced apart on the side of the third straight section 1561 away from the loading / unloading port 1501. The fourth straight section 1563 may be located on the side of the third straight section 1561 near the top wall of the receiving cavity 150. The second lifting section 1562 may extend obliquely from the inner end of the third straight section 1561 to the outer end of the fourth straight section 1563. The fourth straight section 1563 may extend from the inner end of the second lifting section 1562 toward the interior of the receiving cavity 150. The second sliding part 2502 can slide from the second lifting section 1562 into the fourth straight section 1563, and move along the fourth straight section 1563 into the cavity 150, so that the water receiving box 25 maintains the distance between the top and side walls of the cavity 150, and the water receiving box 25 can be placed stably in the cavity 150.

[0148] like Figure 15 , Figure 17 and Figure 18 As shown, during the process of the water receiving box 25 being pushed into the receiving cavity 150, the first sliding part 2501 and the second sliding part 2502 can enter the receiving cavity 150 sequentially. The second sliding part 2502 can slide into the receiving cavity 150 sequentially along the third straight section 1561, the second lifting section 1562, and the fourth straight section 1563. Conversely, during the process of the water receiving box 25 being pulled out of the receiving cavity 150, the second sliding part 2502 and the first sliding part 2501 can exit the receiving cavity 150 sequentially. The second sliding part 2502 can slide out of the receiving cavity 150 sequentially along the fourth straight section 1563, the second lifting section 1562, and the third straight section 1561.

[0149] like Figure 18 and Figure 19 As shown, in some embodiments, the length of the third straight segment 1561 is less than the length of the first straight segment 1551. When the second sliding portion 2502 enters the third straight segment 1561, the distance between the first sliding portion 2501 and the first lifting segment 1552 and the distance between the second sliding portion 2502 and the second lifting segment 1562 are equal. The first straight segment 1551 and the third straight segment 1561 are arranged relatively parallel. The first lifting segment 1552 and the second lifting segment 1562 are arranged relatively parallel. Thus, when the first sliding part 2501 slides along the first straight section 1551 to the first lifting section 1552, the second sliding part 2502 can simultaneously slide along the third straight section 1561 to the second lifting section 1562. This allows the second sliding part 2502 to slide synchronously along the second lifting section 1562 while the first sliding part 2501 slides along the first lifting section 1552. Consequently, the inner and outer ends of the water receiving box 25 are simultaneously raised, improving the stability of the sliding process of the water receiving box 25 and preventing the water receiving box 25 from tilting during the sliding process.

[0150] like Figure 19 and Figure 20 As shown, in some embodiments, the second straight section 1553 and the fourth straight section 1563 are arranged in parallel. When the first sliding part 2501 slides along the first lifting section 1552 to the second straight section 1553, the second sliding part 2502 slides along the second lifting section 1562 to the fourth straight section 1563. This allows the second sliding part 2502 to slide synchronously with the fourth straight section 1563 while the first sliding part 2501 slides along the second straight section 1553. This maintains the consistent height of the inner and outer ends of the water receiving box 25, improves the stability of the sliding process of the water receiving box 25, and prevents the water receiving box 25 from tilting during the sliding process.

[0151] like Figure 15 , Figure 17 and Figure 19 As shown, in some embodiments, a clearance area 1554 may be provided on the upper side of the first straight section 1551. A third sliding part 2503 may be provided on the outer wall of the water receiving box 25. The third sliding part 2503 is used to slide along the first sliding groove 155. The third sliding part 2503 and the first sliding part 2501 are located at the same height on the outer wall of the water receiving box 25, and the third sliding part 2503 is disposed between the first sliding part 2501 and the second sliding part 2502. The third sliding part 2503 can enter the receiving cavity 150 before the second sliding part 2502. The first sliding part 2501 and the third sliding part 2503 can enter the first straight section 1551 one after the other and slide synchronously along the first straight section 1551. By having the first sliding part 2501 and the third sliding part 2503 move synchronously along the first straight section 1551, the stability of the water receiving box 25 during the sliding process of the first straight section 1551 can be improved, and the height of the inner and outer ends of the water receiving box 25 can be kept consistent. Before the second sliding part 2502 enters the receiving cavity 150, it prevents the water receiving box 25 from tilting during the sliding process.

[0152] like Figure 19 , Figure 20 and Figure 21 As shown, in some embodiments, when the first sliding part 2501 slides within the first lifting section 1552 and the second straight section 1553, the third sliding part 2503 is located within the clearance area 1554. The clearance area 1554 provides space for the third sliding part 2503 to move, preventing the third sliding part 2503 from obstructing the sliding of the first sliding part 2501 within the first lifting section 1552 and the second straight section 1553. When the third sliding part 2503 enters the clearance area 1554, the second sliding part 2502 has already entered the second sliding groove 156. The cooperation of the first sliding part 2501 and the second sliding part 2502 can maintain the smoothness of the sliding of the water receiving box 25 and prevent the water receiving box 25 from tilting during the sliding process.

[0153] like Figure 13 , Figure 14 , Figure 15 and Figure 17As shown, in some embodiments, the bottom of the receiving cavity 150 may have a bottom opening 1502, which is exposed on the bottom surface of the base 15. When the first sliding part 2501 slides along the first straight section 1551, the bottom of the water receiving box 25 can extend out of the bottom opening 1502, at which time the bottom of the water receiving box 25 can be arranged in the space below the bottom surface of the base 15. During the pushing and pulling process of the water receiving box 25, the bottom of the water receiving box 25 can move downward through the bottom opening 1502, thereby using the space below the receiving cavity 150 for movement; and after the water receiving box 25 is pushed into the receiving cavity 150, it can return to the receiving cavity 150 because the water receiving box 25 is lifted, which helps to reduce the height requirement of the receiving cavity 150 and reduce the space occupied by the receiving cavity 150 inside the dehumidifier.

[0154] In some embodiments, a limiting portion 2504 may be provided on the side wall of the water receiving box 25. The limiting portion 2504 is provided on the side of the side wall of the water receiving box 25 near the outer panel 2521. When the water receiving box 25 is pushed into the receiving cavity 150, the limiting portion 2504 can extend into and engage at the entrance of the second slide groove 156, that is, the limiting portion 2504 can extend into and engage at the entrance of the third straight section 1561.

[0155] like Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, the top of the water receiving box 25 may be provided with an elastic arm 254 extending toward the outer panel 2521. A latch 2541 is provided on the top surface of the elastic arm 254. A slot 1503 may be provided in the area near the loading / unloading port 1501 on the top wall of the receiving cavity 150. The slot 1503 is arranged opposite to the latch 2541. When the water receiving box 25 is pushed into the receiving cavity 150, after the water receiving box 25 is pushed into place, the latch 2541 can engage with the slot 1503 to lock the water receiving box 25 within the receiving cavity 150, improving the stability of the water receiving box 25 within the housing 1. Furthermore, pressing the elastic arm 254 can separate the latch 2541 from the slot 1503, facilitating the unlocking of the water receiving box 25 and allowing it to be pulled out of the receiving cavity 150.

[0156] like Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, the outer ends of the elastic arms 254 are spaced apart above the top surface of the water receiving box 25. When the latch 2541 engages with the slot 1503, the outer ends of the elastic arms 254 are exposed through the access port 1501 and the outer panel 2521. The exposed ends of the elastic arms 254 allow the user to easily press them, thereby separating the latch 2541 from the slot 1503, facilitating the unlocking of the water receiving box 25, and allowing it to be pulled out of the receiving cavity 150.

[0157] like Figure 12 As shown, in some embodiments, the handle groove 2522 is located below the elastic arm 254, and the outer end of the elastic arm 254 is arranged vertically opposite to the handle groove 2522. By arranging the outer end of the elastic arm 254 vertically opposite to the handle groove 2522, when unlocking the water container 25, the user can insert part of their fingers into the handle groove 2522 while pressing the exposed end of the elastic arm 254 with the other part of their fingers. Then, when the latch 2541 separates from the slot 1503, the user can easily pull the water container 25 out of the receiving cavity 150 through the handle groove 2522, improving the convenience of pulling out the water container 25.

[0158] like Figure 12 and Figure 13 As shown, in some embodiments, two sets of handle grooves 2522 and elastic arms 254 can be provided. The two sets of handle grooves 2522 and elastic arms 254 are arranged at a left-right interval. Correspondingly, two locking slots 1503 can also be provided, with the two locking slots 1503 and the two elastic arms 254 arranged opposite to each other. In this way, the two locking slots 1503 cooperate with the two elastic arms 254 to improve the firmness of the water receiving box 25 locked in the receiving cavity 150, and allow the user to unlock the water receiving box 25 by simultaneously unlocking the two elastic arms 254 with both hands and simultaneously pulling the two handle grooves 2522 with both hands, reducing the difficulty of pulling out the water receiving box 25 and making the water receiving box 25 easy to pull out.

[0159] Figure 22 yes Figure 12 A top view of the water receiving box 25. Figure 23 yes Figure 22 Sectional view along the AA direction.

[0160] like Figure 14 , Figure 15 , Figure 22 and Figure 23 As shown, in some embodiments, the top surface of the water receiving box 25 is provided with a clearance window 2512 arranged opposite to the water suction pipe 274. During the process of pushing the water receiving box 25 into the housing 1 and into the receiving cavity 150, the lower end of the water suction pipe 274 can enter the clearance window 2512, and the lower end of the water suction pipe 274 can be suspended in the clearance window 2512, allowing the lower end of the water suction pipe 274 to extend into the water receiving box 25. The clearance window 2512 reduces interference between the lower end of the water suction pipe 274 and the top surface of the water receiving box 25, making it easier for the lower end of the water suction pipe 274 to enter the water receiving box 25 during the process of pushing the water receiving box 25 into the receiving cavity 150. The water suction pipe 274 is suspended at the clearance window 2512, so that the lower end of the water suction pipe 274 can maintain a certain distance from the inner bottom surface of the water receiving box 25, which facilitates the suction of water from the inside of the water receiving box 25 and discharge through the drain pump 27.

[0161] like Figure 12 , Figure 13 and Figure 14 As shown, in some embodiments, a through hole 153 is provided on the top surface of the base 15. The through hole 153 is located above the top wall of the receiving cavity 150 and communicates with the receiving cavity 150. The water suction pipe 274 can be inserted and fixed in the through hole 153, and the lower end of the water suction pipe 274 extends through the through hole 153 and is arranged inside the receiving cavity 150. The water suction pipe 274 can be fixed through the through hole 153, so that the lower end of the water suction pipe 274 is stably suspended in the receiving cavity 150. When the water receiving box 25 is pushed into the receiving cavity 150, the lower end of the water suction pipe 274 can be stably suspended inside the water receiving box 25.

[0162] like Figure 7 , Figure 8 and Figure 13 As shown, in some embodiments, a positioning tube 2445 may be provided at the bottom of the fan cover 244, and the positioning tube 2445 is located below the drain pump 27. The suction pipe 274 extends downward and is fixed inside the positioning tube 2445. The positioning tube 2445 may be arranged opposite to the perforation 153. After the lower end of the suction pipe 274 passes through the positioning tube 2445 and the perforation 153, it extends downward and is arranged inside the receiving cavity 150. By fixing the suction pipe 274 with the positioning tube 2445, the lower end of the suction pipe 274 can be fixed inside the perforation 153, thereby making the lower end of the suction pipe 274 stably suspended inside the receiving cavity 150.

[0163] like Figure 7 and Figure 8 As shown, in some embodiments, the positioning tube 2445 can be inserted into the perforation 153, and the water suction tube 274 can be inserted and fixed in the perforation 153 through the positioning tube 2445.

[0164] Figure 24 yes Figure 15 Structure diagram in another state.

[0165] like Figure 14 , Figure 15 and Figure 24As shown, in some embodiments, the suction pipe 274 has a flexible hose structure. During the process of pushing the water receiving box 25 into the housing 1 and into the receiving cavity 150, the lower end of the suction pipe 274 can contact the water receiving box 25, causing the suction pipe 274 to bend and deform; until the lower end of the suction pipe 274 enters the clearance window 2512, the suction pipe 274 can return to its original shape, and the suction pipe 274 is suspended in the clearance window 2512, with its lower end extending into the water receiving box 25. The hose structure of the suction pipe 274 enables it to bend and deform, and also allows it to return to its original shape. During the process of pushing the water receiving box 25 in, the interference and collision between the suction pipe 274 and the water receiving box 25 can be reduced, making it easier for the lower end of the suction pipe 274 to enter the water receiving box 25. This simplifies the docking structure between the suction pipe 274 of the drain pump 27 and the water receiving box 25, and solves the docking problem between the suction pipe 274 of the drain pump 27 and the water receiving box 25 during the process of pushing or taking the water receiving box 25 in or out.

[0166] like Figure 22 , Figure 23 and Figure 24 As shown, in some embodiments, the clearance window 2512 may be located on the side of the top surface of the water receiving box 25 away from the outer panel 2521. The clearance window 2512 may extend along the pushing and pulling direction of the water receiving box 25. The clearance window 2512 may extend to the side edge of the top surface of the water receiving box 25 away from the outer panel 2521. When the water receiving box 25 is pushed into the receiving cavity 150, the lower end of the suction pipe 274 may preferentially abut against the side edge of the top surface of the water receiving box 25 away from the outer panel 2521. By extending the clearance window 2512 to the side edge of the top surface of the water receiving box 25 away from the outer panel 2521, the lower end of the suction pipe 274 can more easily enter the clearance window 2512, reducing interference and collision between the suction pipe 274 and the water receiving box 25.

[0167] like Figure 23 and Figure 24 As shown, in some embodiments, a first transition rib 2514 may be provided on the side edge of the clearance window 2512 away from the outer panel 2521. The surface of the first transition rib 2514 is an arc surface. The arc surface of the first transition rib 2514 may be arranged facing the clearance window 2512. During the process of the water receiving box 25 being pushed into the receiving cavity 150, the lower end of the water suction pipe 274 can move along the arc surface of the first transition rib 2514 and then enter the clearance window 2512. Through the arc surface of the first transition rib 2514, the friction between the lower end of the water suction pipe 274 and the surface of the first transition rib 2514 can be reduced, allowing the lower end of the water suction pipe 274 to enter the clearance window 2512 more smoothly.

[0168] like Figure 23 and Figure 24As shown, in some embodiments, a second transition rib 2505 may be provided at the top edge of the outer side wall of the water receiving box 25 away from the outer panel 2521. The second transition rib 2505 is arranged opposite to the first transition rib 2514. The arc surface of the first transition rib 2514 may be arranged facing away from the clearance window 2512. During the process of the water receiving box 25 being pushed into the receiving cavity 150, the lower end of the water suction pipe 274 can move sequentially along the arc surface of the second transition rib 2505 and the arc surface of the first transition rib 2514 before entering the clearance window 2512. When the water receiving box 25 is pushed into the receiving cavity 150, the lower end of the water suction pipe 274 may preferentially abut against the second transition rib 2505 and sequentially enter the clearance window 2512 along the surfaces of the second transition rib 2505 and the first transition rib 2514. The arc surface of the second transition rib 2505 can reduce the friction between the lower end of the water suction pipe 274 and the surface of the second transition rib 2505, allowing the lower end of the water suction pipe 274 to enter the clearance window 2512 more smoothly.

[0169] Figure 25 yes Figure 12 An exploded view of the water receiving box 25.

[0170] like Figure 23 , Figure 24 and Figure 25 As shown, in some embodiments, an expansion portion 2506 may be provided on the outer wall of the water receiving box 25 away from the outer panel 2521. An expansion groove 2507 is provided within the expansion portion 2506, communicating with the interior of the water receiving box 25. The expansion groove 2507 is arranged opposite to the clearance window 2512. The clearance window 2512 may extend above the top of the expansion groove 2507 and communicates with the expansion groove 2507. The expansion portion 2506 and the expansion groove 2507 can increase the length of the clearance window 2512, further reducing interference and collision between the bottom end of the suction pipe 274 and the water receiving box 25 when the water receiving box 25 is pushed into the receiving cavity 150.

[0171] like Figure 23 , Figure 24 and Figure 25 As shown, in some embodiments, the first transition rib 2514 may be disposed above the expansion groove 2507, and the second transition rib 2505 may be disposed at the top edge of the outer wall of the expansion portion 2506. The upper side of the expansion groove 2507 can provide space for the second transition rib 2505, and the top edge of the expansion portion 2506 can provide space for the second transition rib 2505. When the water receiving box 25 is pushed into the receiving cavity 150, the lower end of the water suction pipe 274 can preferentially abut against the expansion portion 2506, and sequentially enter the clearance window 2512 along the surfaces of the second transition rib 2505 and the first transition rib 2514.

[0172] like Figure 14, Figure 22 and Figure 23 As shown, in some embodiments, a water collection trough 2551 may be provided on the inner bottom surface of the water receiving box 25. The water collection trough 2551 is recessed downward on the inner bottom surface of the water receiving box 25. The bottom surface of the water collection trough 2551 is lower than the inner bottom surface of other areas within the water receiving box 25, thereby allowing water in the water receiving box 25 to be collected in the water collection trough 2551 first, increasing the water depth in the water collection trough 2551. The water collection trough 2551 is located below the clearance window 2512. When the water receiving box 25 is pushed into the receiving cavity 150, the lower end of the suction pipe 274 can be suspended above the water collection trough 2551, allowing the lower end of the suction pipe 274 to preferentially draw water from the water collection trough 2551, improving the drainage efficiency within the water receiving box 25.

[0173] like Figure 14 As shown, in some embodiments, the lower end of the suction pipe 274 can extend downwards to the opening of the water collection tank 2551. In this case, there is sufficient distance between the lower end of the suction pipe 274 and the bottom surface of the water collection tank 2551, which can meet the requirements of the suction efficiency of the suction pipe 274 and prevent blockage at the lower end of the suction pipe 274. Simultaneously, the lower end of the suction pipe 274 can be lowered close to other inner bottom surfaces within the water receiving box 25, thereby facilitating the drainage of water from the water receiving box 25, increasing the single-pump capacity of the drain pump 27, reducing the number of times the drain pump 27 starts, and thus reducing the noise generated by the drain pump 27.

[0174] like Figure 14 and Figure 23 As shown, in some embodiments, a water collection section 2523 can be formed in the area corresponding to the water collection tank 2551 at the bottom of the water receiving box 25. The bottom surface of the water collection section 2523 can protrude from the bottom surface of other areas of the water receiving box 25, thereby locally increasing the depth inside the water receiving box 25. When the water receiving box 25 is pushed into the receiving cavity 150, the bottom surface of the water receiving box 25 can be located at the bottom opening 1502, and the bottom surface of the water receiving box 25 can be flush with the bottom surface of the base 15, with only the bottom surface of the water collection section 2523 protruding below the bottom surface of the base 15, thereby reducing the space occupied below the receiving cavity 150.

[0175] Figure 26 yes Figure 22 Sectional view along the BB direction. Figure 27 yes Figure 25 A partial decomposition diagram of the middle part of the structure. Figure 28 yes Figure 27 Top view of the middle box.

[0176] like Figure 25 and Figure 28As shown, in some embodiments, a water collection box 25 may be provided with a water pumping zone 255. Condensate enters the water collection box 25 downwards through the water inlet 2511 and then flows to the water pumping zone 255. A clearance window 2512 may be arranged above the water pumping zone 255. The lower end of the suction pipe 274 may extend into the water pumping zone 255. A water collection tank 2551 may be provided on the bottom surface of the water pumping zone 255. When the drain pump 27 is operating, the drain pump 27 can draw water from the water pumping zone 255 through the lower end of the suction pipe 274 and discharge it.

[0177] like Figure 25 and Figure 28 As shown, in some embodiments, a water flow channel 256 may be provided inside the water receiving box 25. One end of the water flow channel 256 may extend below the water receiving hole 2511 and communicate with the water receiving hole 2511. The other end of the water flow channel 256 may communicate with the pumping area 255. In this way, the condensate flowing down from the evaporator 23 can flow into the water flow channel 256 through the water receiving hole 2511 and flow along the water flow channel 256 to the pumping area 255, so that the water entering the water receiving box 25 can be deposited and filtered in the water flow channel 256, preventing impurities such as mud, sand, and lint from entering the pumping area 255 and the drain pump 27, thereby effectively preventing the drain pump 27 from becoming clogged.

[0178] like Figure 25 and Figure 26 As shown, in some embodiments, a first water filter 257 may be provided inside the water receiving box 25. The first water filter 257 is arranged obliquely from bottom to top within the water flow channel 256. When water flows from the water flow channel 256 to the pumping area 255, the water flowing through the water flow channel 256 can pass through the first water filter 257 and flow from below the first water filter 257 to above the first water filter 257 before flowing into the pumping area 255. In this way, after the water in the water flow channel 256 is filtered by the first water filter 257 before entering the pumping area 255, impurities such as mud, sand, and lint can be prevented from entering the pumping area 255, effectively preventing the drain pump 27 from becoming clogged and extending the service life of the drain pump 27. By arranging the first water filter 257 at an angle from bottom to top within the water flow channel 256, the contact area between the first water filter 257 and the water within the water flow channel 256 can be increased. Alternatively, a larger first water filter 257 can be placed within the water receiving box 25, thereby improving the space utilization efficiency within the water receiving box 25. This addresses the problem of the small area of ​​the water filter inside the water receiving tray and improves the issue of the water filter mesh being easily clogged.

[0179] like Figure 25 and Figure 26As shown, in some embodiments, the water flow channel 256 may include a sedimentation zone 2561. A first water filter 257 may be arranged obliquely from bottom to top within the sedimentation zone 2561. The first water filter 257 can divide the space within the sedimentation zone 2561 into a lower space 25611 and an upper space 25612. The lower space 25611 is located below the first water filter 257, and the upper space 25612 is located above the first water filter 257. The lower space 25611 can communicate with the water inlet 2511 through other parts of the water flow channel 256. The upper space 25612 can communicate with the pumping zone 255 through other parts of the water flow channel 256. When condensate enters the water receiving box 25 through the water inlet 2511 and flows into the pumping zone 255 through the water flow channel 256, the water in the water flow channel 256 can flow through the sedimentation zone 2561. Heavier particles such as silt and sand can gradually settle in the lower space 25611. After flowing through the first water filter screen 257, impurities such as lint will also be blocked on the lower side of the first water filter screen 257 and settled in the lower space 25611. This helps to improve the filtration efficiency of the first water filter screen 257, prevents the mesh of the water filter screen from clogging, and further improves the problem of the mesh of the water filter screen being easily clogged.

[0180] like Figure 26 and Figure 27 As shown, in some embodiments, the outer panel 2521 may be provided with a first insertion port 2524, which communicates with the sedimentation area 2561. The first water filter 257 can be inserted into the sedimentation area 2561 at an angle downward through the first insertion port 2524. By providing the first insertion port 2524 on the outer panel 2521, the first insertion port 2524 can be exposed at the pick-up and drop-off port 1501 of the base 15, thereby allowing the outer end of the first water filter 257 to be exposed on the outer side wall of the base 15 and outside the housing 1. This facilitates the user in removing the first water filter 257 for individual cleaning and prevents the mesh of the first water filter 257 from becoming clogged.

[0181] like Figure 27As shown, in some embodiments, a first mounting area 25613 can be formed between the upper space 25612 and the lower space 25611 within the deposition area 2561. The first mounting area 25613 connects the upper space 25612 and the lower space 25611. The first mounting area 25613 extends obliquely toward the first insertion port 2524, and its upper end communicates with the first insertion port 2524. A first water filter 257 can be inserted obliquely downward into the first mounting area 25613 through the first insertion port 2524, thereby placing the first water filter 257 in the area between the upper space 25612 and the lower space 25611. The first mounting area 25613 can spatially separate the upper space 25612 and the lower space 25611, facilitating the alignment and insertion of the first water filter 257 into the first mounting area 25613, and thus enabling the first water filter 257 to be stably and obliquely arranged within the water flow channel 256.

[0182] like Figure 26 and Figure 27 As shown, first guide grooves 25614 may be provided on the opposite side walls of the first installation area 25613. The first guide grooves 25614 extend obliquely upward toward the first insertion port 2524. The upper end of the first guide grooves 25614 communicates with the first insertion port 2524. The first water filter screen 257 can extend into the first insertion port 2524 and be inserted obliquely downward along the first guide grooves 25614 into the first installation area 25613.

[0183] like Figure 26 and Figure 27 As shown, in some embodiments, one end of the first water filter 257 may be exposed outside the first insertion port 2524. The exposed end of the first water filter 257 may be provided with a handle groove 2571, which is exposed outside the outer panel 2521. Through the handle groove 2571 at the outer end of the first water filter 257, the user can easily insert the first water filter 257 into the water receiving box 25, or easily pull the first water filter 257 out of the water receiving box 25.

[0184] like Figure 1 and Figure 11 As shown, in some embodiments, the handle groove 2571 can be exposed on the outer side wall of the base 15, and the handle groove 2571 can be exposed on the outer side wall of the housing 1, thereby facilitating the user to take the first water filter 257 out from the outside of the housing 1, push the first water filter 257 into the water receiving box 25, or pull the first water filter 257 out from the water receiving box 25.

[0185] like Figure 25 , Figure 26 and Figure 27As shown, in some embodiments, a drain port 2525 may be provided on the outer panel 2521. The drain port 2525 is located on the side wall of the lower space 25611 and communicates with the lower space 25611. A sealing element 259 may be provided on the outer wall of the water receiving box 25, and the sealing element 259 is detachably sealed at the drain port 2525. The sealing element 259 allows the user to easily open or close the drain port 2525. When the drain port 2525 is opened, impurities such as mud, sand particles, and lint deposited in the lower space 25611 are discharged from the drain port 2525 into the water receiving box 25, facilitating cleaning of the inside of the water receiving box 25.

[0186] like Figure 25 and Figure 27 As shown, in some embodiments, a connecting rod 2591 is connected to the seal 259. Both the seal 259 and the connecting rod 2591 can be made of flexible material. One end of the connecting rod 2591 is integrally connected to the seal 259, and the other end can be connected to the outer wall of the outer panel 2521. The seal 259 can be fixed to the outer wall of the water receiving box 25 via the connecting rod 2591, preventing the seal 259 from being lost during use.

[0187] like Figure 25 As shown, in some embodiments, the top of the water receiving box 25 is provided with a top cover 251. The top cover 251 can cover the top opening of the water receiving box 25. The water receiving hole 2511 and the clearance window 2512 can be respectively provided on the top cover 251. The top cover 251 can be provided with an extension 2513, and the top of the float switch 253 is exposed through the extension 2513 to abut against the micro switch 154.

[0188] like Figure 25 and Figure 28 As shown, in some embodiments, the water flow channel 256 may include a secondary filtration zone 2562, which is located between the sedimentation zone 2561 and the pumping zone 255. The upper space 25612 is connected to the pumping zone 255 through the secondary filtration zone 2562, and a second water filter screen 258 is provided at the connection between the secondary filtration zone 2562 and the pumping zone 255. Thus, water filtered by the first water filter screen 257 can flow to the secondary filtration zone 2562, be filtered by the second water filter screen 258, and then enter the pumping zone 255, further preventing impurities such as lint from entering the pumping zone 255. The mesh density of the second water filter screen 258 can be higher than that of the first water filter screen 257, thereby allowing smaller lint or particles to be blocked at the second water filter screen 258 and collected in the secondary filtration zone 2562.

[0189] like Figure 25 and Figure 27As shown, in some embodiments, a second insertion port 2515 may be provided on the top surface of the water receiving box 25. The second insertion port 2515 may be provided on the top cover 251. A partition wall may be provided between the secondary filtration zone 2562 and the water pumping zone 255, and a second installation zone 2516 may be provided on the partition wall, which may connect the secondary filtration zone 2562 and the water pumping zone 255. The second insertion port 2515 and the second installation zone 2516 are arranged vertically opposite to each other and are connected. The second water filter screen 258 may be inserted downward into the second installation zone 2516 through the second insertion port 2515. The partition wall can spatially separate the second installation zone 2516 and the water pumping zone 255, making it easier for the second water filter screen 258 to be aligned and inserted into the second installation zone 2516, thereby enabling the second water filter screen 258 to be stably and vertically arranged between the second installation zone 2516 and the water pumping zone 255. In addition, through the second insertion port 2515 on the top surface of the water receiving box 25, the user can easily insert the second water filter 258 into the water receiving box 25, or remove the second water filter 258 from the water receiving box 25.

[0190] like Figure 25 , Figure 27 and Figure 28 As shown, second guide grooves 25161 may be provided on the opposite side walls of the second installation area 2516. The second guide grooves 25161 extend vertically upward toward the second insertion port 2515. The upper end of the second guide grooves 25161 communicates with the second insertion port 2515. The second water filter screen 258 can extend into the second insertion port 2515 and be inserted into the second installation area 2516 at an angle downward along the second guide grooves 25161.

[0191] like Figure 25 and Figure 28 As shown, in some embodiments, the water flow channel 256 includes a curved channel 2563. One end of the curved channel 2563 may extend below and communicate with the water inlet 2511. The other end of the curved channel 2563 may communicate with the lower space 25611. Condensate enters the water receiving box 25 through the water inlet 2511 and flows through the curved channel 2563 to the lower space 25611 of the sedimentation zone 2561. Heavier particles such as silt can gradually settle in the curved channel 2563 and the lower space 25611, preventing the mesh of the water filter from becoming clogged.

[0192] like Figure 28As shown, in some embodiments, a first extending rib 25631 and a second extending rib 25632 may be respectively provided on the opposite side walls of the region where the curved channel 2563 is located. The first extending rib 25631 extends from one side wall of the region where the curved channel 2563 is located toward the opposite side wall and is spaced apart from the opposite side wall. The second extending rib 25632 extends from the other side wall of the region where the curved channel 2563 is located toward the opposite side wall and is spaced apart from the opposite side wall. Multiple first extending ribs 25631 and multiple second extending ribs 25632 may be provided. Multiple first extending ribs 25631 and multiple second extending ribs 25632 are arranged alternately and at intervals to form the curved channel 2563.

[0193] like Figure 25 and Figure 28 As shown, in some embodiments, the water flow channel 256 may include a water receiving area 2564. The water receiving area 2564 is located below the water receiving hole 2511. One end of the curved channel 2563 may extend to and communicate with the water receiving area 2564. The other end of the curved channel 2563 communicates with the lower space 25611. Condensate enters the water receiving box 25 through the water receiving hole 2511, and may first enter the water receiving area 2564, then flow through the curved channel 2563, and flow towards the lower space 25611 of the sedimentation area 2561.

[0194] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
