When the drainage pump 800 is started, the condensed water in the water storage tank 500 is drained through the drainage pump 800, so that the water level in the water storage tank 500 is lowered, the drainage valve is lowered synchronously with the water level in the water storage tank 500 and opens the drainage hole 400, and the condensed water generated in the air duct 300 is drained into the water storage tank 500 through the drainage hole 400; when the drain pump 800 is turned off, the water level in the water storage tank 500 rises, and the float 700 floats in synchronization with the water level in the water storage tank 500 to seal the drain hole 400.

The bottom of the air duct 300 is provided with a drain hole 400, a drain valve is arranged in the water storage tank 500, when the drain pump 800 is started, condensed water in the water storage tank 500 is discharged through the drain pump 800, the water level in the water storage tank 500 drops, the drain valve synchronously drops and opens the drain hole 400, and condensed water generated in the air duct 300 is discharged into the water storage tank 500 through the drain hole 400; when the drain pump 800 is turned off, the water level in the water storage tank 500 rises, the drain valve floats and seals the drain hole 400, and then the water storage tank 500 is isolated from the air duct 300, so that the odor and the water vapor in the water storage tank 500 are prevented from entering the air duct 300, and the water vapor in the water storage tank 500 cannot enter the drum 200 to damp clothes.

In some embodiments, the drain valve includes a float 700, the float 700 is disposed in the water storage tank 500, the float 700 has a density less than that of water, the float 700 can float on the water surface, and the float 700 can open or close the drain hole 400.

In some embodiments, the drain valve further includes a guide 600, the guide 600 being disposed in the water storage tank 500, the float 700 being connected to the guide 600 and guided by the guide 600 such that the float 700 opens or closes the drain hole 400.

Referring to the arrow direction in fig. 10 of the specification, namely, the flow direction of the drying air, during drying, the fan 160 is operated to drive the drying air to directionally circulate in the drying cavity and the air duct 300, the drying air enters the cylinder 200 through the air inlet 201 after being heated by the condenser 150, and passes through the clothes in the cylinder 200, so that the moisture in the clothes is evaporated, the hot air carries the evaporated moisture into the air duct 300 and continuously flows to the evaporator 140, and the moisture in the drying air is condensed to be changed into a liquid state again under the heat exchange effect of the evaporator 140 and is separated from the drying air; the condensed water falls into the water storage tank 500 through the drain hole 400 by gravity.

When the drain pump 800 is started, condensed water in the water storage tank 500 is drained through the drain pump 800, so that the water level in the water storage tank 500 is lowered, the floating block 700 is lowered synchronously with the water level in the water storage tank 500 and opens the drain hole 400, and condensed water generated in the air duct 300 is drained into the water storage tank 900 through the drain hole 400 and then is drained into the water container 130 at the top of the tank body 100. At the same time, the air passing through the evaporator 140 is dried again at a low temperature, and passes through the condenser 150 again under the driving of the blower 160, and starts a new cycle, so that the laundry in the drum 200 is finally dried.

When the drain pump 800 is turned off, condensed water in the water storage tank 900 and the first drain pipe 110 flows back, and the returned condensed water enters the water storage tank 500, so that the water level in the water storage tank 500 rises, and the floating block 700 floats up in synchronization with the water level in the water storage tank 500 and seals the drain hole 400. The drain hole 400 is sealed by the floating block 700 to isolate the water storage tank 500 from the air duct 300, so that the odor in the water storage tank 500 is prevented from entering the air duct 300, and the moisture in the water storage tank 500 cannot enter the drum 200 to moisten the laundry under the condition that the dried laundry is not taken out in the drum 200 for a long time.

While embodiments of the present utility model have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
