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 tank is usually placed at the bottom of the casing. Users need to bend down to lift the water tank, and water is easily spilled when the water tank is pulled out horizontally. Moreover, since the water tank and compressor are both located at the bottom, the volume of the water tank will be reduced due to the size of the compressor. Utility Model Content

[0056] Figure 1 This is a structural diagram of a dehumidifier according to some embodiments of the present invention.

[0057] like Figure 1 As shown in some embodiments of the present invention, the dehumidifier includes a housing 1. The housing 1 can be configured as the outer shell of the dehumidifier. The interior of the housing 1 can be used to provide installation space.

[0058] 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.

[0059] like Figure 1As 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.

[0060] Figure 2 yes Figure 1 An internal structural diagram. Figure 3 yes Figure 2 A structural diagram from another perspective.

[0061] like Figure 2 and Figure 3 As shown, in some embodiments, the dehumidifier includes a refrigeration system, which includes a refrigerant circulation loop. The refrigerant circulation loop may be located within the casing 1. The refrigerant circulation loop includes a compressor 21, a condenser 22, and an evaporator 23 connected end-to-end. The refrigerant circulates within the refrigerant circulation loop formed by the compressor 21, condenser 22, and evaporator 23. The compressor 21 compresses the refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser 22. The condenser 22 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The evaporator 23 evaporates the expanded refrigerant and returns the refrigerant gas, which is in a low-temperature, low-pressure state, to the compressor 21. The evaporator 23 can achieve a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the surrounding environment.

[0062] 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.

[0063] like Figure 2 and Figure 3 As shown, in some embodiments, the housing 1 has a receiving space 10. The refrigerant circulation loop can be located within the receiving space 10. The compressor 21, evaporator 23, and condenser 22 can each be located within the receiving space 10.

[0064] like Figure 2 and Figure 3 As shown, in some embodiments, the receiving space 10 may be located in the lower space inside the housing 1. Thus, the compressor 21, evaporator 23, and condenser 22 may each be located in the lower space inside the housing 1.

[0065] like Figure 1 and Figure 2 As shown, in some embodiments, an air inlet 101 is provided on the outer wall of the housing 1. The air inlet 101 can be located on the side wall of the housing 1. The air inlet 101 can be located on the side wall of the housing 1 corresponding to the accommodating space 10. The air inlet 101 can be arranged opposite to the evaporator 23. The air inlet 101 can be used to introduce indoor air. Indoor air can enter the housing 1 through the air inlet 101, first contacting the evaporator 23, and then condensing and cooling the introduced indoor air. Water vapor condenses on the evaporator 23 to form condensate, reducing the humidity and temperature of the air.

[0066] 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.

[0067] Figure 4 yes Figure 2 Partially decomposed structure diagram.

[0068] like Figure 2 and Figure 4 As shown, in some embodiments, the condenser 22 can be located on one side of the evaporator 23 in the horizontal direction. The condenser 22 can be located on the side of the evaporator 23 away from the air inlet 101. In this way, after indoor air is introduced into the casing 1, it can flow through the evaporator 23 and the condenser 22 in sequence. The evaporator 23 can condense and cool the flowing air, and then the condenser 22 can heat it up before it is discharged back into the room.

[0069] like Figure 1 and Figure 2 As shown, in some embodiments, an air outlet 102 is provided on the outer wall of the housing 1. The air outlet 102 can be located on the side wall of the housing 1. The air outlet 102 can be located on the side wall of the housing 1 corresponding to the accommodating space 10. The air dehumidified by the evaporator 23 and the condenser 22 can flow back into the room through the air outlet 102.

[0070] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the dehumidifier includes a fan assembly 24. The fan assembly 24 is disposed in the receiving space 10 inside the casing 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 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 casing 1. The fan assembly 24 can be used to generate airflow, thereby introducing indoor air into the casing 1, allowing the indoor air to smoothly enter the casing 1 through the air inlet 101, flow sequentially through the evaporator 23 and the condenser 22, enter the fan assembly 24 through the air intake 2411, and then exit the casing 1 through the air exhaust 2412 and the air outlet 102, thus discharging the dehumidified air into the room.

[0071] like Figure 1 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.

[0072] like Figure 3 and Figure 4 As shown, in some embodiments, the fan assembly 24 includes a duct housing 241. The duct housing 241 may be located on the side of the condenser 22 away from the evaporator 23. An air intake 2411 is located on the side of the duct housing 241 facing the condenser 22. An air exhaust 2412 is located on the side of the duct housing 241 facing the air outlet 102. Indoor air enters the housing 1 through the air intake 101, flows sequentially through the evaporator 23 and the condenser 22, enters the duct housing 241 through the air intake 2411, and is then discharged from the housing 1 through the air exhaust 2412 and the air outlet 102.

[0073] 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.

[0074] In some embodiments, the duct housing 241 may be a volute structure. The impeller 242 may be a turbine structure.

[0075] 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.

[0076] like Figure 2 and Figure 4 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. The side of the air cavity 2441 near the duct housing 241 is connected to the air intake 2411. An opening is formed on the side of the air cavity 2441 near the condenser 22. The opening of the air cavity 2441 may be arranged opposite to the side wall of the condenser 22 away from the evaporator 23. The opening of the air cavity 2441 may conform to the contour of the condenser 22. The contour of the condenser 22 may conform to the contour of the evaporator 23 and the contour of the air inlet 101. The air cavity 2441 inside the fan cover 244 can smoothly introduce the indoor air flowing through the evaporator 23 and condenser 22 into the air duct shell 241 through the air intake 2411, thereby improving the air intake efficiency of the indoor air, improving the heat exchange efficiency between the indoor air and the evaporator 23 and condenser 22, and thus improving the dehumidification efficiency of the dehumidifier.

[0077] like Figure 2 and Figure 4 As shown, in some embodiments, the dehumidifier includes a drip tray 25. The drip tray 25 may be disposed within a receiving space 10 inside the housing 1. The drip tray 25 may be disposed in the bottom region of the receiving space 10. The drip tray 25 may be disposed below the evaporator 23. The evaporator 23 may be disposed above the drip tray 25. The condenser 22 may be disposed above the drip tray 25. The drip tray 25 can be used to collect condensate flowing down the outer wall of the evaporator 23. The condensate generated on the evaporator 23 can flow downwards along the outer wall of the evaporator 23 and be collected in the drip tray 25.

[0078] In some embodiments, the dehumidifier includes a support plate 26. The support plate 26 may be disposed on top of the drip tray 25. The evaporator 23 may be supported above the support plate 26. The condenser 22 may be supported above the support plate 26. The support plate 26 may be provided with a drain outlet 261. The drain outlet 261 communicates with the interior of the drip tray 25. The condensate generated on the evaporator 23 may flow down the outer wall of the evaporator 23 onto the support plate 26, and then flow through the drain outlet 261 into the interior of the drip tray 25. The condensate collects in the drip tray 25.

[0079] like Figure 4 As shown, in some embodiments, the dehumidifier includes a drain pump 27. The drain pump 27 may be disposed in a receiving space 10 within the housing 1. The drain pump 27 may be disposed within a drip tray 25. The drain pump 27 can draw water from the drip tray 25 and discharge the water from the drip tray 25.

The water volume in the water tank 3 may be larger than the water volume in the drip tray 25. The drain pump 27 can draw water from the drip tray 25 and drain it into the water tank 3 for collection. Users can periodically clean the water tank 3 to drain the condensate generated inside the dehumidifier, thereby ensuring the long-term stable operation of the dehumidifier.

[0082] like Figure 1 and Figure 5 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, thus improving the convenience of using the water tank 3.

[0083] Figure 6 yes Figure 5 A structural diagram from another perspective.

[0084] like Figure 5 and Figure 6As shown, in some embodiments, the top region of the housing 1 is provided with a recessed area 100. The recessed area 100 may be located above the receiving space 10. The top of the recessed area 100 may be exposed on the top surface of the housing 1. At least a portion of the peripheral sidewall of the recessed area 100 may be exposed on the side wall of the housing 1. The water tank 3 may be detachably installed at the recessed area 100. When the water tank 3 is installed at the recessed area 100 of the housing 1, the top surface of the water tank 3 may be exposed on the top surface of the housing 1, and at least a portion of the peripheral sidewall of the water tank 3 may be exposed on the side wall of the housing 1, with the exposed peripheral sidewall of the water tank 3 corresponding to the exposed peripheral sidewall of the recessed area 100. By exposing the sidewall of the water tank 3, the space inside the housing 1 can be fully utilized, which is beneficial to increasing the effective volume inside the water tank 3.

[0085] like Figure 1 As shown, in some embodiments, when the water tank 3 is installed in the missing area 100 of the casing 1, the exposed peripheral wall of the water tank 3 can be flush with the corresponding peripheral wall of the casing 1. In this way, the effective volume inside the water tank 3 can be increased, while maintaining the flatness and aesthetics of the overall appearance of the dehumidifier.

[0086] like Figure 5 and Figure 6 As shown, in some embodiments, a receiving groove 40 is recessed at the bottom of the missing area 100. The water tank 3 can be placed in the missing area 100 from top to bottom, with the bottom of the water tank 3 placed in the receiving groove 40. In this way, when the water tank 3 is installed in the missing area 100 of the housing 1, the bottom of the water tank 3 can be stably fixed in the receiving groove 40, improving the stability of the water tank 3 within the housing 1.

[0087] Figure 7 yes Figure 5 Structural diagram of the middle water tank 3.

[0088] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, a guide ramp 401 may be provided on the side wall of the receiving groove 40.

In the top-to-bottom direction, the support ramp 301 may be inclined towards the center of the bottom of the water tank 3. When the bottom of the water tank 3 is placed in the receiving groove 40 from top to bottom, the support ramp 301 can slide downwards along the guide ramp 401, allowing the bottom of the water tank 3 to be accurately placed in the receiving groove 40. After the bottom of the water tank 3 is in place in the receiving groove 40, the support ramp 301 can support itself on the guide ramp 401, improving the stability of the bottom of the water tank 3 within the receiving groove 40. Figure 12 The state shown.

[0089] Figure 8 yes Figure 7 A structural diagram from another perspective.

[0090] like Figure 5 and Figure 8 As shown, in some embodiments, a positioning part 402 may be protruding from the bottom surface of the receiving groove 40. A positioning groove 302 that mates with the positioning part 402 may be recessed from the bottom surface of the water tank 3. When the bottom of the water tank 3 is placed in the receiving groove 40 from top to bottom, the positioning part 402 can be fitted into the positioning groove 302, so that the groove wall of the positioning groove 302 is supported on the positioning part 402. The cooperation between the positioning part 402 and the positioning groove 302 can improve the stability of the bottom of the water tank 3 in the receiving groove 40.

[0091] like Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments, a first correction part 403 and a second correction part 404 may be protruding from opposite sides of the bottom surface of the receiving groove 40. A first correction groove 303 and a second correction groove 304 may be recessed from opposite sides of the bottom surface of the water tank 3. The first correction groove 303 may be correspondingly provided with the first correction part 403. The second correction groove 304 may be correspondingly provided with the second correction part 404. When the bottom of the water tank 3 is placed in the receiving groove 40 from top to bottom, the first correction part 403 may be fitted into the first correction groove 303, and the second correction part 404 may be fitted into the second correction groove 304, so that the groove wall of the first correction groove 303 is supported on the top surface of the first correction part 403, and the groove wall of the second correction groove 304 is supported on the top surface of the second correction part 404, thereby adjusting the position of the opposite sides of the bottom of the water tank 3, so that the bottom of the water tank 3 is accurately placed in the receiving groove 40.

[0092] It should be noted that, in other embodiments, a third and a fourth correction section may be provided on the opposite sides of the bottom surface of the receiving tank 40. The third and fourth correction sections can adjust the position of the opposite sides of the bottom of the water tank 3, so that the bottom of the water tank 3 is accurately placed in the receiving tank 40.

[0093] like Figure 6 and Figure 8As shown, in some embodiments, the first correction part 403 may be disposed on the side of the bottom surface of the receiving groove 40 near the guide slope 401. The bottom of the guide slope 401 may be connected to the side edge of the first correction part 403. The first correction groove 303 may be disposed on the side of the bottom surface of the water tank 3 near the support slope 301. The bottom of the support slope 301 may be connected to the side edge of the first correction groove 303. When the support slope 301 slides down along the guide slope 401 to the bottom of the guide slope 401, the first correction part 403 can be smoothly fitted into the first correction groove 303, and the second correction part 404 can be smoothly fitted into the second correction groove 304, adjusting the position of the opposite sides of the bottom of the water tank 3 so that the support slope 301 can be stably supported on the guide slope 401.

[0094] Figure 9 yes Figure 5 Structural diagram of inner liner 4. Figure 10 yes Figure 9 A structural diagram from another perspective.

[0095] like Figure 5 , Figure 9 and Figure 10 As shown, in some embodiments, the dehumidifier includes an inner liner 4. The inner liner 4 is disposed inside the housing 1. The inner liner 4 may be disposed in the top region inside the housing 1. A receiving space 10 may be formed below the bottom of the inner liner 4. A recessed area 100 may be formed in the upper part of the inner liner 4. A receiving groove 40 may be formed inside the inner liner 4. The peripheral sidewall of the top of the housing 1 covers the outer peripheral wall of the inner liner 4. The inner liner 4 can be used to improve the structural strength of the upper region inside the housing 1, so that the water tank 3 can be stably placed at the recessed area 100 and supported on the inner liner 4. In addition, the peripheral sidewall of the top of the housing 1 covering the outer peripheral wall of the inner liner 4 can also improve the structural strength of the upper region inside the housing 1 and keep the dehumidifier's appearance clean.

[0096] In some embodiments, a control section 41 is formed on one side of the liner 4. A recessed area 100 and a receiving groove 40 may be formed on the other side of the liner 4, and located on the same side as the control section 41. The dehumidifier may include a control panel 14. The 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 provides mounting 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 located away from the water tank 3, preventing the control panel 14 from contacting the water in the water tank 3.

[0097] like Figure 3 and Figure 10As shown, in some embodiments, a mounting cavity 410 may be formed on the side of the control unit 41 away from the missing area 100. 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 mounting cavity 410 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.

[0098] like Figure 9 and Figure 10 As 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 groove 40. The receiving groove 40 may be formed enclosingly between the surrounding plate 42 and the sidewall of the control part 41. The top surface of the surrounding plate 42 is lower than the top surface of the control part 41. The missing area 100 may be formed between the top surface of the surrounding plate 42 and the sidewall of the control part 41. The three peripheral sidewalls of the missing area 100, excluding the side where the control part 41 is located, are respectively exposed to the peripheral sidewall of the housing 1. The peripheral sidewall of the water tank 3 may be exposed to the corresponding peripheral sidewall of the housing 1 at the three exposed peripheral sidewalls of the missing area 100, thereby increasing the volume of the water tank 3 and increasing the effective internal volume of the water tank 3.

[0099] In some embodiments, the receiving slot 40 can be a slot structure with a square outline. The surrounding plate 42 can be arranged around three slot sidewalls forming the square-shaped receiving slot 40, and the sidewall of the control unit 41 facing the missing area 100 can form a fourth slot sidewall of the square-shaped receiving slot 40. The peripheral sidewall of the top of the housing 1 can respectively cover the outer wall of the surrounding plate 42 and the outer wall of the control unit 41. At this time, the peripheral sidewall of the water tank 3 can be arranged flush with the peripheral sidewall of the housing 1 corresponding to the surrounding plate 42.

[0100] It should be noted that in some other embodiments, the missing area 100 may have only one or two peripheral sidewalls exposed on the peripheral sidewall of the housing 1. In this case, the top surface of part of the enclosure 42 may extend upward to the top surface of the control unit 41 to cover the outer sidewall of the water tank 3.

[0101] like Figure 6 and Figure 8 As shown, in some embodiments, a support step 305 is provided at the lower end of the peripheral sidewall of the water tank 3. The support step 305 can be arranged vertically opposite to the enclosure 42. When the water tank 3 is placed from top to bottom within the gap 100, the support step 305 can be supported on the top surface of the corresponding sidewall of the enclosure 42 and the housing 1, thereby improving the structural stability of the water tank 3.

[0102] like Figure 5 and Figure 9 As shown, in some embodiments, a storage groove 411 may be provided on the side wall of the control unit 41 facing the missing area 100. The roller 13 may be detachably provided on the bottom of the housing 1. The roller 13 can be removed from the bottom of the housing 1 and placed in the storage groove 411, thereby facilitating the user to install the roller 13 as needed. For example, when the user does not want to install the roller 13, the roller 13 can be placed in the storage groove 411 to prevent the roller 13 from being lost. When the roller 13 needs to be installed, the roller 13 is taken out from the storage groove 411 and installed on the bottom surface of the housing 1. In addition, when the water tank 3 is placed at the missing area 100, the water tank 3 can cover the storage groove 411 to prevent the roller 13 from being exposed on the housing 1.

[0103] Figure 11 yes Figure 10 Top view. Figure 12 yes Figure 1 A cross-sectional view.

[0104] like Figure 8 , Figure 9 and Figure 12 As shown, in some embodiments, a recessed relief groove 405 is provided on the bottom surface of the inner liner 4.

The compressor capacitor 211 is located in the top region of the receiving space 10. The compressor capacitor 211 can be located below the bottom of the inner liner 4, and the top of the compressor capacitor 211 can be snapped into and received within the relief groove 405. The relief groove 405 provides installation space for the compressor capacitor 211, improving the utilization rate of the space inside the housing 1. Furthermore, a positioning part 402 can be formed on the bottom surface of the receiving groove 40 at a position corresponding to the relief groove 405. When the bottom of the water tank 3 is placed in the receiving groove 40 from top to bottom, the positioning part 402 can fit into the positioning groove 302 on the bottom surface of the water tank 3, so that the groove wall of the positioning groove 302 is supported on the positioning part 402. The cooperation between the positioning part 402 and the positioning groove 302 can improve the stability of the bottom of the water tank 3 in the receiving groove 40.

[0105] like Figure 9 , Figure 10 and Figure 12As shown, in some embodiments, the guide ramp 401 may be provided on the side wall of the enclosure 42 away from the control part 41. The first correction part 403 may be provided on the side of the bottom surface of the receiving groove 40 away from the control part 41. The second correction part 404 may be provided on the side of the bottom surface of the receiving groove 40 close to the control part 41. When the bottom of the water tank 3 is placed in the receiving groove 40 from top to bottom, the first correction part 403 and the second correction part 404 can adjust the relative positions of the bottom sides of the water tank 3, adjust the distance between the water tank 3 and the control part 41, so that the bottom of the water tank 3 is accurately placed in the receiving groove 40, avoiding collision or squeezing between the water tank 3 and the control part 41.

[0106] like Figure 5 As shown, in some embodiments, a nozzle 43 may be provided on the side wall of the control unit 41 facing the vacancy area 100. The outlet end of the drain pump 27 may be connected to the nozzle 43. When the water tank 3 is placed at the vacancy area 100, the nozzle 43 may be arranged facing the inside of the water tank 3. The drain pump 27 draws water from the water receiving tray 25 and sprays it into the water tank 3 through the nozzle 43, where it is collected.
