Abstract
Disclosed are a self-cleaning washing machine and a control method thereof. The washing machine includes inner and outer drums defining a chamber therebetween, a wave wheel, a water drainage apparatus, cleaning pellets provided in the chamber for cleaning drum walls between the inner and outer drums, and an isolating structure for preventing the cleaning pellets from escaping from the chamber. The isolating structure includes a filtration mechanism arranged in the water drainage apparatus to prevent the cleaning pellets from being flushed away when water is drained, and/or a grid mechanism arranged at the bottom of the inner drum to prevent the cleaning pellets from entering the inner drum. Operably, in the water-draining and/or spin-dry process, the inner drum is controlled to carry out different actions, making the cleaning pellets together with the water flow through a water drainage opening to be collected by a water drainage valve.
