SELF-CLEANING WASHING MACHINE AND CONTROL METHOD THEREOF

摘要

Disclosed are a self-cleaning washing machine and a control method. The washing machine comprises an outer drum (1), an inner drum (2), a wave wheel (3) and a water drainage apparatus (4), wherein cleaning pellets (6) to clean the inner wall of the outer drum and the outer wall of the inner drum are provided in a chamber (5) between the inner drum (2) and the outer drum (1). The washing machine is provided with an isolating structure preventing the cleaning pellets (6) from escaping from the chamber (5), wherein the isolating structure comprises a filtration mechanism (7) arranged in the water drainage apparatus (4) to stop the cleaning pellets (6) being drained away when the water is drained and/or a grid mechanism (8) arranged at the bottom part of the inner drum to stop the cleaning pellets (6) entering the inner drum (2) from the bottom of the inner drum, and also comprises a filtration grid (9) arranged at a water overflow port (11) of the outer drum to stop the cleaning pellets (6) flowing out with the overflow water and an outer drum cover (10) arranged at the top part of the outer drum to cover the annular opening of the chamber (5). After the washing has finished, in the process of draining water and/or in the spin-dry process, the inner drum (2) is controlled to carry out different actions, making the cleaning pellets (6) together with the washing water flow through a water drainage opening, to be collected by a water drainage valve (44). The present invention has a simple structure, can effectively clean the drum walls between the inner and outer drums, and prevents the number of cleaning pellets from reducing.

主权项

1. A self-cleaning washing machine, comprising:
an outer drum; an inner drum; a wave wheel; a water drainage apparatus; cleaning pellets provided in a chamber defined between the inner drum and the outer drum for cleaning an inner wall of the outer drum and an outer wall of the inner drum; and an isolating structure for preventing the cleaning pellets from escaping from the chamber, wherein the isolating structure comprises at least one of a filtration mechanism arranged in the water drainage apparatus to prevent the cleaning pellets from being flushed away when water is drained, and a grid mechanism arranged at the bottom part of the inner drum to prevent the cleaning pellets from entering the inner drum from the bottom of the inner drum.
