Abstract

See full text

An inner drum cover is provided at a drum opening of an inner drum of a washing machine, the inner drum cover is used to open or close the drum opening, so that the inner drum forms a closed container after the drum opening is closed by the inner drum cover. The inner drum can perform washing after the inner drum cover is correspondingly fastened to the drum opening, so that clothes only come into contact with washing water in the sealed inner drum in a washing process. In this way, a case in which the clothes are contaminated because washing water between the inner drum and an outer drum flows into the inner drum is avoided, washing cleanliness of the washing machine is greatly improved, and incomplete washing of the clothes caused by contamination of the washing water between the inner drum and the outer drum is avoided.
