Washing machine and control method thereof

Abstract

The invention belongs to the technical field of washing machines, and discloses a washing machine and a control method thereof.The washing machine comprises an inner barrel, a drainage hole is formed in the barrel bottom of the inner barrel, the washing machine further comprises a sealing mechanism arranged below the inner barrel, and the sealing mechanism blocks the drainage hole to form the closed inner barrel and is used for independently containing washing water; the washing machine further comprises a pushing part capable of spirally ascending / descending, and the pushing part is driven by the driving mechanism to spirally ascend to push the sealing mechanism to block the drainage hole. According to the washing machine, the pushing piece spirally ascends to push the sealing mechanism to block the drainage hole, the inner barrel can independently contain water for washing, rotation of the inner barrel does not affect the positions of the pushing piece and the sealing mechanism, the inner barrel does not need to be positioned before the drainage hole is opened and blocked, control logic is simple, and implementation is easy.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine and a control method thereof. Background technique [0002] Existing washing machines generally include an outer tub and an inner tub disposed inside the outer tub, and a plurality of dewatering holes are provided on the tub wall of the inner tub, so that the inner tub and the outer tub communicate with each other. When the washing machine is working, the outer bucket holds washing water, and the inner bucket holds the laundry to be washed. Part of the washing water exists between the inner and outer buckets, but this part of the washing water is not actually used, resulting in a waste of washing water. . On the other hand, the dirt and lint in the washing water may stay in the space between the inner tub and the outer tub. With the increase of the working time of the washing machine, the dirt and lint gradually accumulate, which is difficult to clea...

AI Technical Summary

Problems solved by technology

However, the driving mechanism and the positioning structure for realizing the locking of the inner tub need to be controlled by separate driving elements, the control logic is complicated, and the separate positioning structure also makes the assembly of the washing machine more cumbersome.

At the same time, the arrangement of multiple driving elements increases the manufacturing cost of the washing machine
