When the rotary tub and the pulsator are rotated in a state in which laundry and detergent are introduced into the rotary tub, the pulsator stirs wash water together with the laundry introduced into the rotary tub, thereby removing dirt from the laundry.
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, because the problem of depositing water between interior bucket and the outer bucket can lead to breeding the dirt in the region between the outer wall of interior bucket, the inner wall of outer bucket and interior bucket and outer bucket, pollutes user's clothing, seriously influences user's laundry experience.

The principle of the waterless washing machine between the inner barrel and the outer barrel is that whether the inner barrel and the outer barrel are communicated or not in the washing process is realized by controlling the opening and closing of a water outlet at the bottom of the inner barrel. In washing and rinsing process, interior bucket bottom outlet is closed, at this moment under motor drive, the outlet is stopped up in the rising of drainage valve plug, because interior bucket outlet need pinpoint for the position of fixing the drainage valve plug on outer bucket and guarantee sealed effect, a locating pin actuating mechanism who is used for interior bucket circumferencial direction location has been increased, when needing the outlet to close, the locating pin stretches out, interior bucket slowly rotates, go into the only locating hole of interior bucket bottom portion until the locating pin card, the position is the position of interior bucket bottom outlet and drainage valve plug centering this moment, the drainage valve plug stretches out and stops up the outlet. When the water needs to be drained, the drain valve plug is lowered, then the positioning pin is withdrawn, and the water draining and dewatering procedure is started.
The drainage process of the existing inter-barrel waterless washing machine is complex to control, and the motion of two motors needs to be respectively controlled to realize the positioning of the circumferential direction of the inner barrel and the opening and closing of the drainage outlet of the inner barrel.
