Background

Washing machines are largely classified into pulsator type, pulsator type and drum type washing machines. The pulsator type washing machine performs a washing operation by rotating a pulsator at the center of a washing tub left and right. The agitator type washing machine performs a washing operation using a frictional force between water current and laundry by rotating a rotary blade at the center of a washing tub in the left-right direction. The drum type washing machine performs a washing operation by beating laundry by rotating a drum.

An outer tub and an inner tub are provided in a cabinet of a washing machine, and the inner tub is an important part of washing, and generally, a hole is provided in a tub wall for introducing washing water into the inner tub or for dehydrating laundry in the inner tub. A large amount of dirt and bacteria are bred between the inner barrel and the outer barrel due to the long-time flowing and accumulation of the washing water, secondary pollution is generated to clothes, and the washing machine is not beneficial to the health of a human body, so that the washing machine with the imporous inner barrel is provided.
