Description

A washing machine Technical field

The invention belongs to the technical field of washing machines, and particularly relates to a washing machine with only a rotatable inner tub that can hold water.

In view of this, how to set up a washing machine to combine the inner and outer tubs so that the inner tub is set as a sealed container, which can not only contain water and clothes, but also rotate and beat the clothes for washing; at the same time, because the washing machine does not have an outer tub , Or the outer tub is integrated with the washing machine shell, which can also expand the inner tub of the washing machine to expand the washing capacity of the washing machine, which has become a research hotspot.

However, since the inner tub is not only used to hold washing water, but also rotates to beat and clean the tub underwear, how to provide a dehydration structure and a drainage structure suitable for the above-mentioned washing machine has become an urgent problem to be solved.
