Abstract

A washing machine comprises an inner drum, wherein a drum bottom of the inner drum is installed with an inner drum bottom cover, and the inner drum bottom cover is in sealed connection with the drum bottom of the inner drum to form a sealed space. Such a setting avoids problems of breeding of bacteria and generation of smudge caused when washing water enters the inner drum bottom cover and is deposited in a chamber formed between the inner drum bottom cover and the drum bottom of the inner drum in a process of washing clothes by a washing machine.
