The invention provides a self-cleaning device of a full-automatic washing
machine, which is used for solving the problem of secondary
contamination on clothes caused by clustered
dirt in the interlayer between the
water storage tank and the
dehydration tank, and in the interlayer between the
dehydration tank bottom and the
impeller bottom of the washing
machine. The interlayer between the
water storage tank and the
dehydration tank is provided with a plurality of clean balls 3, and a plurality of clean balls 5 are arranged between the dehydration tank bottom and the
impeller bottom. When the washing
machine washes or rinses, the clean balls perform friction with the
water storage tank wall, the dehydration tank wall, the
impeller bottom and the dehydration tank bottom to clean the
dirt inthe positions, and simultaneously the clean balls are self cleaned through mutual collision and friction. By adopting the way in which the
water storage tank rotates along with the dehydration tank when dehydrating and the
storage tank wall or bottom is provided with a groove or a
piston cylinder (to lead the clean balls to drop into the groove or the
piston cylinder when dehydrating), the clean balls do not generate friction with the dehydration tank, thus prolonging the service life of the clean balls and saving energy; and the adoption of the way in which the
water storage tank rotates along with the dehydration tank when dehydrating can decrease the width of the interlayer between the
water storage tank and the dehydration tank to save water.
