[0041] An embodiment of the present invention provides a dehumidifier. Figure 1 This is a three-dimensional schematic diagram of an embodiment of a dehumidifier of the present invention. Figure 2This is a perspective diagram of an embodiment of a dehumidifier according to the present invention, with some external structures omitted. The dehumidifier includes a body 100, a first water tank 500, a first water receiving tray 200, and a second water receiving tray 300. The first water tank 500 is detachably mounted on the body 100.

[0042] Figure 3 、 Figure 4 The following are three-dimensional schematic diagrams of the first and second water trays in different positions in one embodiment of a dehumidifier according to the present invention. The first water tray 200 is mounted on the body 100 and is used to collect condensed water generated during dehumidification. The second water tray 300 is detachably connected to the body 100 and is located on the bottom side of the first water tray 200 and on top of the first water tank 500.

[0043] Figure 5 This is a top view of the first water receiving tray and the second water receiving tray in an embodiment of the dehumidifier of the present invention, with the second water receiving tray in a disassembled state. Figure 6 The first water receiving tray 200 includes a first water storage tank 210 and a plurality of through holes 220 , each of which is provided through the bottom of the first water storage tank 210 .

[0044] The second water receiving tray 300 includes a second water tank 310, a first drain assembly 320, and a mud retaining structure 330. The second water tank 310 is used to receive condensed water flowing from the plurality of through-holes 220. The first drain assembly 320 is disposed in the second water tank 310. The first drain assembly 320 connects the second water tank 310 with the first water tank 500. The mud retaining structure 330 is disposed in the second water tank 310 and is used to prevent at least some solid impurities in the condensed water from flowing with the condensed water.

[0045] A dehumidifier according to an embodiment of the present invention includes a main body 100, a first water tank 500, a first water receiving tray 200, and a second water receiving tray 300. The first water receiving tray 200 includes a first water storage tank 210 and a plurality of through-holes 220, each of which extends through the bottom of the first water storage tank 210. The second water receiving tray 300 is detachably connected to the main body 100 and disposed on the bottom side of the first water receiving tray 200. The second water receiving tray 300 is also located on the top side of the first water tank 500. The second water receiving tray 300 includes a second water tank 310, a first drainage assembly 320, and a mud retaining structure 330. The second water tank 310 is used to receive condensed water flowing from the multiple through-holes 220 of the first water tank 210. The first drainage assembly 320 is disposed in the second water tank 310 and connects the second water tank 310 with the first water tank 500. The mud retaining structure 330 is disposed in the second water tank 310 and is used to prevent at least some solid impurities in the condensed water from flowing with the condensed water. When the air contains impurities, the condensed water produced by the dehumidifier during dehumidification will be mixed with the impurities already in the air. The mud retaining structure 330 in the second water receiving tray 300 blocks the impurities, allowing them to accumulate in the second water receiving tray 300. When the impurities accumulated in the second water receiving tray 300 reach a level that requires cleaning, the second water receiving tray 300 can be removed from the main body 100 for cleaning. In the above dehumidifier, since the second water receiving tray 300 has the mud retaining structure 330 and is detachably connected to the body 100 , it is easy to disassemble and clean the second water receiving tray 300 , that is, to clean the impurities accumulated on the second water receiving tray 300 .

[0046] Figure 7 The first water receiving tray 200 is provided with a plurality of guide tubes 230 on the surface facing the second water receiving tray 300 , each guide tube 230 being arranged around a corresponding through hole 220 .

[0047] In some embodiments, the height of the guide tube 230 protruding from the surface of the first water receiving tray 200 is 2 to 5 mm. In one example, the height of the guide tube 230 protruding from the surface of the first water receiving tray 200 is 4 mm.

[0048] In the above embodiment, since a plurality of guide tubes 230 are provided on the surface of the first water receiving tray 200 facing the second water receiving tray 300, when the dehumidifier is operated at an angle or there is scale on the bottom surface of the first water receiving tray 200, the guide tubes 230 can prevent unnecessary flow of condensed water, thereby reducing the risk of water leakage in the dehumidifier.

[0049] Figure 8 、 Figure 9Figure 3 shows three-dimensional diagrams of the second water receiving tray in one embodiment of a dehumidifier according to the present invention from different perspectives. In some embodiments, the second water receiving tray 300 further includes a drainage member 340, the position of which corresponds to the position of the through-hole 220. The drainage member 340 protrudes from the bottom of the second water storage tank 310 toward the through-hole 220. Each drainage member 340 includes multiple drainage ribs, and the orthographic projections of the multiple drainage ribs on the bottom of the second water storage tank 310 form a centrally symmetrical pattern.

[0050] By arranging a drainage member 340 under each through hole 220, the condensed water in the through hole 220 first falls on the top of the drainage member 340, and then flows along the drainage member 340 to the bottom of the second water storage tank 310, thereby avoiding the condensed water in the through hole 220 directly falling on the bottom of the second water storage tank 310 and generating a loud dripping sound, thereby reducing the dripping noise of the dehumidifier and improving the user experience of the dehumidifier.

[0051] The second water storage tank 310 has a side wall 310a. In some embodiments, the second water receiving tray 300 further includes a retaining wall 350. The retaining wall 350 is disposed outside the side wall 310a of the second water storage tank 310 and is spaced apart from the side wall 310a. The retaining wall 350 surrounds at least a portion of the second water storage tank 310.

[0052] The second water storage tank 310 is used to store condensed water. During operation, its temperature is lower than the ambient temperature, so secondary condensed water is easily generated on the outer surface of the side wall 310a of the second water storage tank 310. In the above embodiment, the second water receiving tray also includes a water retaining wall 350. The water retaining wall 350 is disposed outside the side wall 310a of the second water storage tank 310 and is spaced apart from the side wall 310a, thereby further reducing the leakage of condensed water and secondary condensed water.

[0053] In some embodiments, a thermal insulation layer 360 is attached to the bottom surface of the second water receiving tray 300, and the thermal insulation layer 360 at least covers the location of the second water storage tank 310. The thermal insulation layer 360 is, for example, a thermal insulation sponge.

[0054] In the above embodiment, the second water storage tank 310 is used to store condensed water, which is lower in temperature than the ambient temperature during operation and requires insulation. By attaching the insulation layer 360 to the bottom surface of the second water receiving tray 300, the second water receiving tray 300 is insulated without affecting its easy removal.

[0055] Figure 10 In some embodiments, the first drainage assembly 320 includes a first drainage hole 321 , a first mounting seat 322 , a swinging member 323 , and a first elastic member 324 .

[0056] The first drain hole 321 is set through the bottom of the second water storage tank 310, and the first drain hole 321 can be connected to the first water tank 500. The first mounting seat 322 is set at the bottom of the second water storage tank 310. The swinging member 323 is swingably connected to the first mounting seat 322. The swinging member 323 includes a first blocking portion 3231, and the swinging member 323 can swing to a first position and a second position. In the first position, the first blocking portion 3231 blocks the first drain hole 321, and in the second position, the first blocking portion 3231 leaves the first drain hole 321, so that the first drain hole 321 is open. The first elastic member 324 elastically connects the swinging member 323 to the first mounting seat 322, and the first elastic member 324 is used to reset the swinging member 323 to the first position. In one example, the first elastic member 324 is a torsion spring.

[0057] like Figure 3 In some embodiments, the dehumidifier further includes a second water tank 600 , which is installed on the body 100 .

[0058] like Figure 8 In some embodiments, the second water receiving tray 300 further includes a second drainage assembly 370 disposed in the second water storage tank 310 , and the second drainage assembly 370 can connect the second water storage tank 310 with the second water tank 600 .

[0059] In some embodiments, a water pump is provided in the second water tank 600 , and the water pump is configured to transport the liquid in the second water tank 600 to the outside of the dehumidifier when turned on.

[0060] The first water tank 500 is detachably connected to the main body 100 and can store condensed water. When a large amount of condensed water accumulates in the first water tank 500, it can be removed from the main body 100, the condensed water inside can be poured out, and the tank can be reattached to the main body 100 for recycling. The second water tank 600 is equipped with a water pump. When it is necessary to continuously drain the condensed liquid from the second water tray 300 directly to the outside of the dehumidifier, the water pump can be used to transport the condensed liquid through the second water tank 600 to the outside of the dehumidifier.

[0061] In some embodiments, the dehumidifier includes a first drainage mode, the first drainage component 320 connects the second water storage tank 310 with the first water tank 500, the second drainage component 370 can disconnect the connection between the second water storage tank 310 and the second water tank 600, and the condensed water received by the second water receiving tray 300 enters the first water tank 500 through the first drainage component 320.

[0062] In some embodiments, the dehumidifier includes a second drainage mode. In the second drainage mode, the first drainage component 320 can disconnect the connection between the second water storage tank 310 and the first water tank 500, and the second drainage component 370 connects the second water storage tank 310 with the second water tank 600. The water pump is turned off, and the condensed water received by the second water receiving tray 300 enters the second water tank 600 through the second drainage component 370 under the action of its own gravity. The condensed water in the second water tank 600 flows out to the outside of the dehumidifier under the action of its own gravity.

[0063] In some embodiments, the dehumidifier includes a third drainage mode. In the third drainage mode, the first drainage component 320 can disconnect the connection between the second water storage tank 310 and the first water tank 500, and the second drainage component 370 connects the second water storage tank 310 with the second water tank 600. The water pump is turned on, and the condensed water received by the second water receiving tray 300 enters the second water tank 600 through the second drainage component 370. The condensed water in the second water tank 600 flows out to the outside of the dehumidifier under the action of the water pump.

In some embodiments, the second drainage assembly 370 includes a second drainage hole 371 , a first movable rod 372 , and a second elastic member 373 .

[0065] The second drain hole 371 is provided through the first water receiving tray 200 and is connected to the second water tank 600. A first movable rod 372 is movably provided in the second drain hole 371. A second blocking portion 3721 is provided at one end of the first movable rod 372. The first movable rod 372 is movable to a third position and a fourth position. In the third position, the second blocking portion 3721 blocks the second drain hole 371. In the fourth position, the second blocking portion 3721 moves away from the second drain hole 371, allowing the second drain hole 371 to be opened. A second elastic member 373 elastically connects the first movable rod 372 to the second water receiving tray 300 and is used to return the first movable rod 372 to the third position.

[0066] like Figure 6 In some embodiments, the first water receiving tray 200 further includes a connecting hole 240 , which is set through the bottom of the first water storage tank 210 and corresponds to the position of the second drain hole 371 .

[0067] like Figure 3 、 Figure 4 In some embodiments, the dehumidifier further includes a push rod assembly 400, which is disposed on the first water receiving tray 200. Figure 6The push rod assembly 400 includes a push rod 410 passing through the connecting hole 240 . The push rod assembly 400 can push the first movable rod 372 through the push rod 410 , so that the first movable rod 372 moves from the third position to the fourth position.

[0068] Figure 12 This is a perspective exploded schematic diagram of a push rod assembly in an embodiment of a dehumidifier of the present invention.

In some embodiments, the push rod assembly 400 further includes a second mounting base 420, a third elastic member 430, a rotary motor 440, and a cam 450.

[0069] The second mounting base 420 is disposed on the first water receiving tray 200. The second mounting base 420 defines a movable passage 421 corresponding to and communicating with the connecting hole 240. The push rod 410 extends through the movable passage 421 and can move along the movable passage 421 toward or away from the first movable rod 372. The end of the push rod 410 facing away from the first movable rod 372 defines an abutment portion 411.

[0070] A third elastic member 430 elastically connects the push rod 410 to the second mounting base 420. A rotary motor 440 is mounted on the second mounting base 420. A rotation center 451 of a cam 450 is connected to the output shaft of the rotary motor 440. At least a portion of the circumference of the cam 450 is an abutment surface 452, which abuts the abutment portion 411. The distance between the abutment surface 452 and the rotation center 451 of the cam 450 gradually increases along a predetermined direction.

[0071] During the first rotation of the cam 450, the radius of the actual contact point X1 between the contact surface 452 and the contact portion 411 gradually increases, and the push rod 410 moves toward the second drainage hole 371 and pushes the first movable rod 372, so that the first movable rod 372 moves to the fourth position.

[0072] During the rotation of the cam 450 along the second turning direction, the radius of the actual abutment point X1 between the abutment surface 452 and the abutment portion 411 gradually decreases. Under the action of the second elastic member 373 and the third elastic member 430, the push rod 410 moves in the direction away from the second drainage hole 371, and the first movable rod 372 gradually returns to the third position.

[0073] In this embodiment, the radius of the actual contact point X1 between the contact surface 452 and the contact portion 411 is the distance from the actual contact point X1 between the contact surface 452 and the contact portion 411 to the rotation center 451 of the cam 450 .

[0074] In some embodiments, the rotation center 451 of the cam 450, the actual contact point X1 between the contact surface 452 and the contact portion 411, and the center axis of the movable channel 421 are located on the same straight line, so that there is no force component offset when the push rod 410 is subjected to force, thereby reducing the friction between the push rod 410 and the movable channel 421 and reducing the risk of the cam 450 getting stuck or stuck.

[0075] like Figure 8 In some embodiments, the second water storage tank 310 includes a main body sub-tank 311 and a communication sub-tank 312 that are interconnected. The orthographic projections of the plurality of through-holes 220 on the bottom of the second water storage tank 310 are located within the main body sub-tank 311. The first drain assembly 320 is disposed in the main body sub-tank 311, and the second drain assembly 370 is disposed in the communication sub-tank 312.

[0076] In some embodiments, the mud retaining structure 330 includes a filter 331, which is disposed at the connection point between the main body sub-slot 311 and the communication sub-slot 312. When the second water receiving tray 300 is removed from the body 100, the filter 331 can be removed and cleaned.

[0077] like Figure 8 In some embodiments, the mud-blocking structure 330 includes a plurality of mud-blocking protrusions 332 distributed along the bottom of the second water storage tank 310. In some embodiments, the mud-blocking protrusions 332 are spaced apart from each other by a plurality of wall-like protrusions. When the condensed water in the second water storage tank 310 passes through the mud-blocking protrusions 332, impurities (such as mud and sand) tend to adhere to the mud-blocking protrusions 332, allowing the mud-blocking structure 330 to collect the impurities.

[0078] like Figure 1 、 Figure 2 In this embodiment, the dehumidifier also includes other well-known components, for example, a compressor, a condenser, an evaporator, a throttling device, a fan, a controller, a power supply, etc. The above components can be arranged in a well-known manner in the dehumidifier, so that the dehumidifier can condense the moisture in the air into condensed water and collect the condensed water.

[0079] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
