Abstract
A self-cleaning washing machine includes an outer tub and an inner tub, a chamber between the outer tub and the inner tub is provided with cleaning particles for cleaning the inner wall of the outer tub and the outer wall of the inner tub, an accommodating chamber for collecting the cleaning particles is connected to a drainage outlet of the outer tub; a shield cover arranged at the drainage outlet rises or falls with the change of the water level in the washing machine or the control device to open or at least partially close the drainage outlet so that the cleaning particles flow into the chamber or back into the accommodating chamber. By setting the shield cover, the cleaning particles are not sucked out from the accommodating chamber and enter between the inner tub and the outer tub to avoid noise when the washing machine is dewatering.
