Technical Field

The invention belongs to the field of household appliances, and particularly relates to a drum washing machine.

Background

The existing roller washing machine generally comprises an inner barrel and an outer barrel which are mutually sleeved, wherein the outer barrel is a water containing barrel, the inner barrel is used for containing clothes and is used for rolling and washing the clothes through rotating the inner barrel, a gap is reserved between the inner barrel and the outer barrel, dirt can be accumulated after the washing machine is used for a period of time, the inner barrel outer wall and the outer barrel inner wall cannot be directly washed due to the mutual sleeving of the inner barrel and the outer barrel, bacteria in the washing machine are increased, the health of a user is influenced, and the user can only wash the inner barrel outer wall and the outer barrel inner wall.

In order to solve the problems, the inner barrel of the drum washing machine is designed into the inner barrel with a non-porous structure, so that water holding and washing can be realized, the non-porous washing machine solves the problem of dirt accumulation between the interlayers of the inner barrel and the outer barrel, and simultaneously, the waste of water resources is reduced. However, the problem of water inlet of the non-porous inner cylinder is difficult, and how to realize efficient and reliable water inlet makes the problem to be solved urgently.

The present invention has been made in view of this situation.
