In the prior art, a drum washing machine generally comprises an inner drum and an outer drum which are mutually sleeved, wherein the outer drum is sealed and used for containing water, and the inner drum is used for containing clothes and beating and washing the clothes by rotating the inner drum; meanwhile, the inner barrel is provided with dehydration holes, so that water in the outer barrel flows into the inner barrel through the dehydration holes to soak the clothes in the inner barrel, the water in the inner barrel flows out of the outer barrel through the dehydration holes, and moisture on the clothes in the inner barrel is discharged to the outer barrel through the dehydration holes when the inner barrel rotates at a high speed, so that the aim of washing the clothes is fulfilled.
However, because the inner cylinder and the outer cylinder are mutually sleeved, dirt is easily accumulated between the inner cylinder and the outer cylinder in the use process of the washing machine; meanwhile, because the inner drum and the outer drum are mutually sleeved, a user cannot clean the outer wall of the inner drum and the inner wall of the outer drum, so that bacteria in the washing machine are increased, and the washing efficiency of the washing machine and the cleanliness of washed clothes are reduced.
Meanwhile, in the existing washing machine, the outer cylinder is sleeved outside the inner cylinder, and clothes are beaten and washed through the rotation of the inner cylinder in the washing process of the washing machine, so that the washing capacity of the washing machine is based on the inner cylinder, the utilization rate of the internal space of the washing machine is low, and the washing capacity of the washing machine cannot be expanded on the existing basis.
In view of this, how to provide a washing machine, so as to integrate the inner and outer drums, and make the inner drum be a sealed container, which can not only contain water and clothes, but also rotate to beat the clothes for washing; meanwhile, because the washing machine is not provided with the outer cylinder or the outer cylinder and the washing machine shell are integrally arranged, the inner cylinder of the washing machine can be expanded to expand the washing capacity of the washing machine, and the development hotspot is generated.
However, since the inner tub is not only used for containing washing water, but also rotated to beat and clean clothes in the tub, how to provide a drainage structure suitable for the above washing machine becomes a problem to be solved urgently.
