Referring to fig. 1 to 3, a water tank assembly includes a tank 100 and a float valve 200, the float valve 200 being rotatably coupled to the tank 100, the float valve 200 including: a rotation shaft 220 rotatably connected to the case 100; a float 210 disposed above the case 100 and connected to the rotation shaft 220; a connecting arm 230 connected to the rotating shaft 220 and capable of rotating to a position of triggering the switch 300; the float 210 and the connection arm 230 are connected to both axial ends of the rotation shaft 220, respectively.

When the dehumidifier works, the water tank is not full of water, the floater 210 drives the connecting arm 230 to rotate under the action of self gravity, so that the connecting arm 230 rotates to the position of the trigger switch 300, the contact switch 300 is switched on, and the dehumidifier works normally; when the dehumidifier is full of water, the floater 210 rises under the buoyancy of the water to drive the connecting arm 230 to rotate to a position far away from the contact switch 300, the switch 300 is switched off, and the dehumidifier stops dehumidifying; because the float valve 200 is rotatably fitted to the tank, the fitting area is much smaller than the sliding fitting area of the float valve 200 and the linear guide, and thus the possibility of the float valve 200 being stuck is greatly reduced.

The float 210 and the connecting arm 230 are respectively connected to two axial ends of the rotating shaft 220, so that the buoyancy and gravity of the float 210 can be used to drive the connecting arm 230 to rotate, and the connecting arm 230 can rotate to the position of the trigger switch 300 or to the position separated from the trigger switch 300.

The switch 300 can adopt various forms to enable the connecting arm 230 to trigger the switch 300 or separate from the switch, for example, a mechanical contact switch 300 is adopted, when the water level in the water tank of the dehumidifier is low, the water tank floater 210 descends, and when the connecting arm 230 rotates to trigger the contact switch 300, the contact switch 300 is triggered by the connecting arm 230, and the dehumidifier dehumidifies; when the water level in the water tank rises to a certain height, the floater 210 floats upwards to drive the connecting arm 230 to rotate to be separated from the contact switch 300, the dehumidifier stops working, and a user is reminded to pour water; the photoelectric switch 300 can also be used, so that when the end of the connecting arm 230 far away from the rotating shaft 220 rises, the photoelectric switch 300 can be triggered by blocking light.

Further, when a user draws out the water tank to pour water, the connecting arm 230 is in a state of being separated from the contact switch 300, the dehumidifier stops working, and the condition that the dehumidifier works when the water tank is drawn out to enable condensed water to splash is effectively prevented.

As shown in fig. 2, in order to prevent the humidity above the water tank from being too high, which affects the operation of the switch 300 and causes the dehumidifier to malfunction, the connecting arm 230 is extended out of the box 100; at this time, a part of the connecting arm 230 and the switch 300 are deviated from the upper part of the water tank, and the influence of high humidity on the switch 300 is effectively reduced.

In order to prevent the contact area between the connecting arm 230 and the contact switch 300 from being too small and from being blocked after long-term use, an arc-shaped arm 240 is arranged at one end of the connecting arm 230 extending out of the box body 100, and the arc surface of the arc-shaped arm 240 is used for abutting against the contact switch 300; wherein, the arcwall face can effectively reduce the probability dead with contact switch 300 card.

Further, a plurality of connection arms 230 may be connected to the rotation shaft 220.

In order to further enhance the function of the dehumidifier, the connecting arms 230 may be arranged in a staggered manner in the circumferential direction of the rotating shaft 220, a plurality of switches 300 at different positions are respectively arranged corresponding to the connecting arms 230, when the water tank is full of water, one of the arc-shaped arms 240 rotates and is separated from the switch 300, the compressor of the dehumidifier stops working, and at this time, the other connecting arm 230 can trigger the other switch 300, so that the water suction pump electrically connected with the switch 300 starts working, and the condensed water in the water tank is pumped out.

As shown in fig. 3, the water tank is provided with a connection hole 120, and the rotation shaft 220 is in clearance fit with the connection hole 120; at this time, the friction force between the rotating shaft 220 and the connecting hole 120 is greatly reduced compared to the interference fit, and the situation that the float valve 200 is stuck is further reduced.

As shown in fig. 3, a handle 130 may be rotatably coupled to the case 100 in order to facilitate the user to grip the case 100 after drawing out the case 100.

In addition, a transparent window 110 can be arranged on the tank body, so that a user can directly observe the water level in the water tank conveniently.

According to another aspect of the present embodiment, there is provided a dehumidifier including: the contact switch 300 is electrically connected with a control system of the dehumidifier; in the above-described water tank assembly, the connection arm 230 can be rotated to a position where the contact switch 300 is triggered or a position where the contact switch 300 is released by the float 210.

As shown in fig. 2, the contact switch 300 includes: a body 310 electrically connected with the control system; a rotating member 320 rotatably connected to the body 310 and capable of rotating to a position where the body 310 is triggered or disengaging therefrom; the rotary member 320 can abut against the connecting arm 230; the rotating piece 320 is adopted to trigger the circuit, so that the dehumidifier fault caused by the blockage of the switch 300 when the push type contact switch 300 is used can be effectively reduced.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
