In the washing and rinsing process, the water pump 7 is controlled to be started, the water inlet valve on the circulating water pipe is opened, and the water circulating from the water containing barrel 2 to the washing barrel 1 is controlled to be circulated; in the dehydration process, the water pump 7 is controlled to be closed, the water inlet valve on the circulating water pipe is closed, and the water containing barrel 2 cannot circulate to feed water into the washing barrel 1.

The foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited to the above-mentioned embodiment, but is not limited to the above-mentioned embodiment, and any simple modification, equivalent change and modification made by the technical matter of the present invention can be further combined or replaced by the equivalent embodiment without departing from the scope of the technical solution of the present invention.
