Drying system and clothes treatment device

Technical Field

The invention relates to the technical field of household equipment, in particular to a drying system and a clothes treatment device.

Background

The existing washing machine comprises a shell, an outer barrel and an inner barrel which are arranged in the shell, wherein the inner barrel is rotatably arranged in the outer barrel. In order to realize the dehydration function of clothes, the wall of the inner barrel is fully distributed with dehydration holes, so that when clothes are washed, washing water can flow between the inner barrel and the outer barrel through the dehydration holes, and the washing water cannot be fully utilized, thereby causing waste of water resources.

In addition, due to the problem of water storage between the inner barrel and the outer barrel, dirt is bred in the outer wall of the inner barrel, the inner wall of the outer barrel and the area between the inner barrel and the outer barrel, clothes of a user are polluted, and if the cleaning is not carried out for a long time, secondary pollution is caused to the clothes in the washing process.

In order to solve the above problems, chinese patent CN201410215346.3 proposes a drum washing machine, which has a main structural feature that the peripheral wall of the inner tub has no holes, so that when washing, only water is in the inner tub, and no water is between the inner tub and the outer tub, thereby not only saving water consumption for washing, but also preventing dirt from breeding between the inner tub and the outer tub, avoiding clothes pollution, improving washing effect, and improving user experience.

Because the peripheral wall of the inner barrel is not provided with holes, the arrangement mode of the air inlet and the air outlet of the traditional washing and drying integrated machine is not suitable for the non-hole inner barrel type washing machine.
