Title:
INNER TUB AND NO-CLEAN WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/165925
Kind Code:
A1
Abstract:
The invention relates to an inner tub. The inner tub is provided with a plurality of lifting ribs extending along an inner tub construction line; the interior of the lifting rib is hollow; a water-repelling surface of the lifting rib is provided with a plurality of water-permeable holes, such that the hollow portion of the lifting rib is in communication with the interior of the inner cylinder; and the rear end of the lifting rib is provided close to the bottom of the inner tub and is provided with a water outlet structure. Further disclosed is a no-clean washing machine. The washing machine is arranged with the inner tub; the inner tub is a container which is sealed when an opening thereof is closed by a door cover; and when the inner tub rotates at a high speed, the washing water is directed to flow to the bottom of the inner tub, and flow, along a water guiding channel provided at the bottom of the inner tub, to the center of the bottom of the inner tub, and then is drained out of the inner tub via a water outlet of a center joint.
By means of providing a plurality of lifting ribs on the side wall of the inner tub, when the inner tub rotates at a high speed, the washing water flowing along a wall is blocked by the lifting ribs and flows into the inside of the lifting ribs, and flows, along an inner chamber of the lifting ribs, towards the bottom of the inner tub due to the centrifugal force, thereby avoiding the occurrence of a low drainage rate resulting from the turbulent flow of the washing water.
