Optionally, an annular groove is formed in the periphery of the water pan 10, the annular groove forms an auxiliary water pan 10, a water receiving port of the auxiliary water pan 10 is higher than a water receiving port of the water pan 10, and when the auxiliary water pan 10 is full of water, the water can overflow into the water pan 10.

Preferably, the filtering structure 60 is arranged at the water outlet, the filtering structure 60 has a filtering cavity 64, the filtering cavity is provided with a second water outlet 63, the second water outlet 63 is connected with the water outlet pipe 30, a first filtering hole 61 is formed on the side wall of the filtering cavity 64, a second filtering hole 62 is arranged at the bottom of the filtering cavity 64, and water in the water receiving tray 10 sequentially passes through the first filtering hole 61, the second filtering hole 62 and the second water outlet 63 and enters the water outlet pipe 30. Through setting up first filtration hole 61, second filtration hole 62, can filter the impurity granule in the condensate water, avoid the outlet jam to cause the drainage unsmooth, also prevent the problem of too big granule jam in drain pipe 30 simultaneously. Optionally, the filtering structure 60 extends into the water-receiving tray 10 from the bottom of the water-receiving tray 10, and the first filtering hole 61 is a vertical long hole extending upward from the bottom surface in the water-receiving tray 10. In order to further filter the large-volume particles, as shown in fig. 4, the width S of the strip-shaped hole is 1mm to 10mm, and the length L of the strip-shaped hole extending upwards from the bottom surface of the water pan 10 is 1mm to 20 mm. The first filtering holes 61 can be round holes in the embodiment, but the blockage of the round holes is not easy to clean.

The filter structure 60 may be fixed at the position of the first drain port 11 by interference fit, foam welding, filling, etc. to prevent water leakage.

Further optionally, as shown in fig. 7, the sectional area of the second filtering hole 62 is larger than the sectional area of the first filtering hole 61, so that the flushing of the first filtering hole 61 by the condensed water can be increased, and if the sectional area of the second filtering hole 62 is too small, the flow rate of the water flowing through the first filtering hole 61 is slow, the resistance is large, the flushing effect is not good, so that the first filtering hole 61 cannot achieve a good cleaning effect.

In the first embodiment of the present embodiment, as shown in fig. 3 to 6, the cleaning mechanism 40 includes: a piston 41 movably arranged in the filter cavity; a driving mechanism 42 for driving the piston 41 to make reciprocating linear motion in the filtering chamber; when the drain 30 is blocked, the piston 41 moves from the top position of the filter chamber to a position below the first filter aperture 61 to increase the pressure in the drain 30; when the piston 41 does not block the water pan 10 to normally drain water, the piston 41 is positioned at the top of the filter chamber; when the water pan 10 is self-cleaned, the piston 41 moves to a position below the first filtering hole 61 to enable the water pan 10 to collect water, and the piston 41 moves to the top position of the filtering cavity.

Alternatively, the filter chamber may have dimensions of 30mm (diameter) by 20mm (height).

When the drive mechanism is used in the first embodiment, the first shaft section is rotatably disposed on the drip tray 10. The piston 41 is driven to reciprocate by the crank-connecting rod 421 mechanism. When the driving mechanism is applied to the second embodiment, the first shaft section is rotatably disposed on the bracket, the bracket is fixed in the casing, the motor drives the first shaft section to rotate, the motor can be fixed on one side of the casing or the water pan of the dehumidifier, and the top of the filter chamber 64 is provided with a sealing cover plate. The second embodiment has two more valves compared to the first embodiment, and the arrangement is relatively complicated.
