As shown in FIG. 1-7, a storable dehumidifier according to an embodiment in a first aspect of the present disclosure includes: a dehumidification device 300 and a water storage assembly 100. The water storage assembly 100 includes a water tank 110, a cavity with a mounting port is formed in the water tank 110, the dehumidification device 300 may be placed in the cavity and enter and exit the cavity from the mounting port. The dehumidification device 300 is provided with a drainage outlet 130, the water storage assembly 100 is provided with a placing member 140 for bearing the dehumidification device 300, the placing member 140 is movably or detachably connected to the water tank 110, the dehumidification device 300 is detachably placed on the placing member 140. The water storage assembly 100 is provided with a water receiving port group 150 in communication with the cavity, and the water receiving port group 150 may correspond to the drainage outlet 130.

The water tank 110 may be selected from various shapes according to actual needs, and shapes of the cavity and the mounting port may be adapted to the dehumidification device 300, so that the dehumidification device 300 may enter and exit the cavity from the mounting port.

However, the placing member 140 may be a bearing block or a bearing rod that is detachably disposed on the water tank 110 through a screw, a buckle or a latch structure. The placing member 140 may also be a bearing block that is rotationally disposed on the water tank. During the rotation of the placing member 140, the placing member 140 may move towards a wall face of the water tank 110 to be folded, or away from the wall face of the water tank 110, to carry the dehumidification device 300.

The placing member 140 may include a cover plate 120, which is movably or detachably connected to the water tank 110 to open or close the mounting port.

Specifically, an end face of the cover plate 120 adjacent to the water tank 110 is provided with a convex ring, which may be inserted into the mounting port of the water tank 110. The cover plate 120 is born by an edge of the mounting port of the water tank 110 such that the water tank 110 is detachably connected to the cover plate 120, thus achieving convenient installation and simple disassembly.

The cover plate 120 may also be rotationally connected to the water tank 110 through a rotating shaft, and the cover plate 120 may be flipped to open or close the mounting port. The cover plate 120 may be connected to the water tank body 110 through a guide slot, and translating the cover plate 120 along the guide slot may also open or close the mounting port.

Alternatively, the cover plate 120 may be detachably connected to the water tank 110 through a buckle structure or a latch structure. The engagement of the buckle structure or the latch structure may cause the cover plate 120 to close the mounting port, and disengagement of the buckle structure or the latch structure may cause the cover plate 120 to open the mounting port.

In some embodiments of the present disclosure, as shown in FIGS. 1-3, the mounting port is positioned at a top of the water tank 110, and the placing member 140 includes an end face of the cover plate 120. That is, when the cover plate 120 is connected to the water tank 110 and the mounting port is closed, the dehumidification device 300 may be placed on the cover plate 120, and the water receiving port group 150 is disposed on the cover plate 120. The drainage outlet 130 may directly face the water receiving port group 150, so that the water flowing out of the drainage outlet 130 may enter the cavity from the water receiving port group 150.

When the dehumidification device 300 is placed in the water tank 110, the mounting port is closed using the cover plate 120, which can effectively prevent dust from entering the cavity.

As shown in FIG. 2, the water receiving port group 150 may be a plurality of water receiving ports disposed on the cover plate 120 or the wall face of the water tank 110.

As shown in FIG. 2, the dehumidification device 300 may also be provided with a handle 320. Specifically, the handle 320 is rotationally connected to the housing 310 of the dehumidification device 300, and the user may lift the dehumidification device 300 through the handle.

When the dehumidifier in the present disclosure needs to be used, the mounting port may be closed using the cover plate 120, the dehumidification device 300 is placed on the placing member 140. The dehumidification device 300 may dehumidify the air, and the condensed water may be discharged from the drainage outlet 130. The water receiving port group 150 corresponding to the drainage outlet 130 may receive the water discharged from the drainage outlet 130 and store the water in the cavity, to prevent the water from leaking to the outside. After use, the user may open the cover plate 120 and pour out the accumulated water in the cavity. At the same time, the dehumidification device 300 is placed into the cavity from the mounting port for storage, reducing the space required for storage and facilitating transportation.

The dehumidification device 300 may be partially or completely placed in the cavity. In the embodiment where the dehumidification device 300 is completely placed in the cavity, the cover plate 120 is used to close the mounting port, and the cover plate 120 and the water tank 110 form a sealed tank. This provides protection and dustproofing for the dehumidification device 300, further enhancing its suitability for transportation and storage.

In an embodiment where the water receiving port group 150 is disposed on the cover plate 120, in order to balance the water passing function and the dustproof effect of the cover plate 120, the cover plate 120 may be movably provided with a baffle plate. Specifically, the baffle plate may rotate or translate relative to the cover plate. The water receiving port group 150 on the cover plate 120 may be blocked or opened by moving the baffle plate. When the dehumidification device 300 is placed in the water tank 110, the baffle plate may block the water receiving port group 150 to prevent dust from entering the cavity.

The dehumidification device 300 may be selected from conventional dehumidification methods, such as rotary dehumidification, semiconductor cooling dehumidification, etc. The dehumidification device 300 is internally provided with a control circuit board, and the control circuit board is used to control the operation of the dehumidification device 300.

In some embodiments of the present disclosure, the water storage assembly 100 is provided with a water level detection assembly, the water level detection assembly is partially positioned in the cavity and electrically connected to the dehumidification device 300. Specifically, the water level detection assembly is connected to the control circuit board, the control circuit board may know the amount of water stored in the cavity through the water level detection assembly. When the water storage amount is too high, the control circuit board prohibits the dehumidification device 300 from operating.

In some embodiments of the present disclosure, an in-position detection assembly is disposed between the dehumidification device 300 and the placing member 140, and the in-position detection assembly is electrically connected to the dehumidification device 300. Similarly, the in-position detection assembly is connected to the control circuit board, when the dehumidification device 300 is accurately placed on the placing member 140 so that the drainage outlet 130 corresponds to the water receiving port group 150, the in-position detection information detected by the in-position detection assembly indicates that the dehumidification device 300 is in place, and the control circuit board allows the dehumidification device 300 to operate.

The water level detection assembly may be a water level sensor and the like disposed in the water tank 110, and the in-position detection assembly may be a Hall sensor, a contact switch and the like disposed between the placing member 140 and the dehumidification device 300.

In some embodiments of the present disclosure, as shown in FIGS. 1 and 3, the water level detection assembly includes a first probe and a second probe. The first probe and the second probe extend into the cavity (not shown). A first conductive end 210 is disposed on the placing member 140, the first probe is electrically connected to the first conductive end 210. The in-position detection assembly includes a second conductive end 220, the second probe is electrically connected to the second conductive end 220. The dehumidification device 300 is provided with a first sampling end 230, a second sampling end 240 and a third sampling end 250. The first sampling end 230 is in conductive contact with the first conductive end 210 and the second sampling end 240 is in conductive contact with the second conductive end 220 to acquire water level detection information. The second sampling end 240 and the third sampling end 250 are both capable of being in conductive contact with the second conductive end 220 to acquire in-position detection information.

The first conductive end 210, the second conductive end 220, the first sampling end 230, the second sampling end 240 and the third sampling end 250 may all be conductive sheets, conductive endpoints, conductive plug-in terminals, etc. When the dehumidification device 300 is placed on the placing member 140, the first conductive end 210 may be in conductive contact with the first sampling end 230, and the second conductive end 220 has a certain length and may be in conductive contact with the second sampling end 240 and the third sampling end 250 simultaneously.

A resistance sampling unit is disposed on the control circuit board, and the resistance sampling unit is connected to the first sampling end 230 and the second sampling end 240, respectively. The resistance sampling unit applies a voltage to the first sampling end 230 and the second sampling end 240 to detect a current between the first sampling end 230 and the second sampling end 240, thus calculating a resistance between the first sampling end 230 and the second sampling end 240. When the amount of water is insufficient, the first probe and the second probe are not submerged, and the resistance between the first sampling end 230 and the second sampling end 240 is relatively large. When the amount of water increases, the water level rises to be in contact with the first probe and the second probe, the water forms a conductive path between the first and second probes, and the resistance between the first sampling end 230 and the second sampling end 240 is reduced, thereby forming the water level detection information.

A short-circuit detection unit may be disposed on the control circuit board. The short-circuit detection unit is electrically connected to the second sampling end 240 and the third sampling end 250, respectively. When both the second sampling end 240 and the third sampling end 250 are in contact with the second conductive end 220, the second sampling end 240 and the third sampling end 250 are short-circuited, thereby forming the in-position detection information.

The above structure is simple, and the functions of water level detection and in-position detection can be completed with fewer parts, thereby reducing production costs.

In some embodiments of the present disclosure, as shown in FIGS. 1-3, the dehumidification device 300 includes a housing 310 and a dehumidification module, a dehumidification chamber is disposed in the housing 310, the dehumidification module is disposed in the housing 310 and positioned in the dehumidification chamber.

At least one second air inlet 530 in communication with the cavity is disposed on the water tank 110, the water receiving port group 150 is positioned at a top of the water tank 110. When the dehumidification device 300 is placed on the water storage assembly 100, the first air inlet 510 corresponds to the water receiving port group 150.

The outside air may enter the cavity from the second air inlet 530, and then enter the dehumidification chamber in the housing 310 from the water receiving port group 150 and the first air inlet 510. After the air is dehumidified by the dehumidification module, the dry air is then discharged from the first air outlet 520, thereby reducing the volume of the dehumidification device 300. The dehumidification module may be a rotary dehumidification module 400, a semiconductor dehumidification module, etc.

In some embodiments of the present disclosure, a plurality of second air inlets 530 are provided, and the plurality of second air inlets 530 are disposed along a peripheral wall of the water tank 110, so that the air around the dehumidifier may enter the dehumidification chamber, thereby improving the dehumidification effect on indoor air.

In some embodiments of the present disclosure, as shown in FIGS. 4-7, the dehumidification device 300 includes a housing 310 and a rotary dehumidification module 400, a dehumidification chamber is disposed in the housing 310, a first air inlet 510 and a first air outlet 520 that are in communication with the dehumidification chamber are disposed on the housing 310, and the rotary dehumidification module 400 is disposed in the housing 310 and positioned in the dehumidification chamber. The rotary dehumidification module 400 utilizes the dehumidification characteristics of the dehumidification rotary wheel 410 to perform physical dehumidification, to achieve a good dehumidification effect and stable operation.

In some embodiments of the present disclosure, as shown in FIGS. 4-6, the rotary dehumidification module 400 includes a dehumidification rotary wheel 410, a drive module 420, a heating module 430 and a condensation module 440. The dehumidification rotary wheel 410 is rotationally arranged on the housing 310 and positioned in the dehumidification chamber. The drive module 420 is disposed in the housing 310 to drive the dehumidification rotary wheel 410 to rotate. A heating air duct 431 as well as a heating component 432 and a first fan 433 that are positioned in the heating air duct 431 are disposed in the heating module 430. The heating module 430 is provided with a second air outlet 540 and a third air inlet 550 that are in communication with the heating air duct 431. The second air outlet 540 faces part of one end face of the dehumidification rotary wheel 410. A condensation air duct is disposed in the condensation module 440, and the condensation module 440 is provided with a third air outlet 560 and a fourth air inlet 570 that are in communication with the condensation air duct. The fourth air inlet 570 faces part of the other end face of the dehumidification rotary wheel 410. A position of the second air outlet 540 corresponds to that of the fourth air inlet 570. The third air inlet 550 is interconnected with the third air outlet 560. The drainage outlet 130 is disposed in the condensation module 440 and communicates with the condensation air duct.

The dehumidification rotary wheel 410 may be made of silica gel, lithium chloride and other materials. The dehumidification rotary wheel 410 is provided with a plurality of through holes to allow air to pass through. At a normal temperature, the dehumidification rotary wheel 410 may absorb moisture in the air, and after being heated, the dehumidification rotary wheel 410 will release the adsorbed moisture.

The drive module 420 may be composed of a motor in combination with a gear. The motor drives the gear to rotate, and the gear drives the dehumidification rotary wheel 410 to rotate.

It should be noted that a second fan 450 may also be disposed in the housing 310. The second fan 450 is used to guide the air flow to enter the dehumidification chamber from the first air inlet 510, pass through the unheated part of the dehumidification rotary wheel 410 to be dehumidified, which is then discharged from the first air outlet 520.

The drive module 420 may be composed of a motor or a rotating cylinder. The drive module 420 is connected to the dehumidification rotary wheel 410 to drive the dehumidification rotary wheel 410 to rotate. The part of the dehumidification rotary wheel 410 that has absorbed moisture will enter the part facing the second air outlet 540. Since the heating component 432 in the heating air duct 431 heats the air flow in the heating air duct 431, the air flow reaches the other end face of the dehumidification rotary wheel 410 from one end face of the dehumidification rotary wheel 410, thus heating the dehumidification rotary wheel 410. The dehumidification rotary wheel 410 releases moisture which reaches the other end face of the dehumidification rotary wheel 410 along the air flow, to enter the condensation air duct from the fourth air inlet 570. In the condensation air duct, the temperature of the air flow drops, and the moisture in the air flow condenses on a wall face of the condensation air duct, water beads flow out of drainage outlet 130, and then the air flow enters the third air inlet from the third air outlet 560 and flows circularly. In this way, the dehumidification rotary wheel 410 can maintain a good dehumidification effect. The heating component 432 may be a semiconductor heating sheet, a heating resistance wire, etc.

In some embodiments of the present disclosure, as shown in FIG. 7, the condensation module 440 further includes a condensation mounting base 441, an adapter base 444 and a plurality of condensation tubes 445. A partition is disposed in the condensation mounting base 441 to divide an interior of the condensation mounting base 441 into a first inner cavity 442 and a second inner cavity 443. A plurality of fourth air outlets 580 communicating with the first inner cavity 442 and a plurality of fifth air inlets 590 communicating with the second inner cavity 443 are disposed on the condensation mounting base 441. The third air outlet 560 communicates with the second inner cavity 443 while the fourth air inlets 570 communicate with the first inner cavity 442. A third inner cavity is disposed in the adapter base 444, the adapter base 444 is provided with a plurality of sixth air inlets 610 and fifth air outlets 600 that are in communication with the third inner cavity. Some of the condensation tubes 445 are each connected with the fourth air outlets 580 at one end, and with the sixth air inlets 610 at another end. Other condensation tubes 445 are each connected with the fifth air outlets 600 at one end and with the fifth air inlets 590 at another end. The drainage outlet 130 is disposed on the condensation mounting base 441 and communicates with the first inner cavity 442 or the second inner cavity 443.

The air flow carrying moisture may be cooled in the condensation tubes 445 to precipitate moisture. The moisture solidifies in inner walls of the condensation tubes 445 to form water beads, and then the water beads flow back to the first inner cavity 442 or the second inner cavity 443, and are discharged from the drainage outlet 130. This design uses the condensation tubes 445 to extend the flowing path of the air flow, so that the air flow is fully cooled, which is conducive to the precipitation of the moisture in the air flow, so that the moisture may be better taken away when passing through the dehumidification rotary wheel 410.
