[0049] When the drying function is turned on, after the external hot air flows through the air inlet 82 and the air inlet pipe 6 into the air passage 321 of the first sub-spray arm 32, a part of the drying gas flows vertically downward through the air port 3212 directly into the auxiliary spray part 4 of the first sub-spray arm 32, causing the auxiliary spray part 4 to rotate and continuously spray drying gas from the spray hole 411. The other part of the drying airflow is sprayed toward the second rotating wheel under the guiding effect of the guide strip, causing the second rotating wheel to rotate, and the rotating second rotating wheel continuously throws the drying gas into the air passages 321 in the other three directions. A part of the gas entering these three air passages is sprayed out through the spray holes, and the other part of the gas enters the auxiliary spray part of the corresponding sub-spray arm, causing the corresponding auxiliary spray part 4 to rotate and continuously spray drying gas from the corresponding spray hole 411.

[0050] The jet holes in the air passage and the rotating drying of the auxiliary spray parts at the four corners realize the dynamic output of drying gas and accelerate the gas flow in the washing chamber. The bottom of the auxiliary spray parts at the four corners is provided with overflow holes. The existence of the overflow holes ensures the effective drying of the bottom surface of the trough. The above design effectively improves the drying effect of the bottom of the washing chamber as a whole and enhances the customer's drying experience.
