Drum washing machine and control method thereof

Abstract

The invention provides a drum washing machine and a control method thereof. The drum washing machine comprises an inner drum, an inner drum drainage port and a resonance drainage device, wherein the inner drum is provided with a washing chamber capable of independently containing washing water; the inner drum drainage port is formed in the inner drum; and the resonance drainage device is installedon the inner drum drainage port to keep the inner drum drainage port in a normally-closed state, and when the rotating speed of the inner drum exceeds a certain value, the resonance drainage device opens the inner drum drainage port. According to the drum washing machine, the resonance drainage device is adopted to control on-off of the inner drum drainage port, the resonance drainage device utilizes the working principle of the washing machine, in the washing or rinsing stage, the rotating speed of the inner drum is low, resonance is not likely to happen to the resonance drainage device, andthe resonance drainage device keeps the inner drum drainage port in a normally-closed state, so that washing water is independently contained in the inner drum in the washing stage and the rinsing stage; and when drainage or dehydration is needed, the inner drum is controlled to rotate at a high speed, the resonance drainage device resonates to do reciprocating motion, the inner drum drainage port is opened in the reciprocating motion process, and drainage of the inner drum is achieved.

Description

technical field [0001] The present invention relates to the technical field of laundry equipment, in particular to a drum washing machine and a control method thereof. Background technique [0002] As the most widely used household appliance in people's daily life, washing machine helps people to get rid of the troubles of laundry and brings great convenience to people. However, the existing washing machines generally include an inner cylinder and an outer cylinder, and a plurality of dehydration holes are distributed on the barrel wall of the inner cylinder, and in the washing process, the washing water between the inner cylinder and the outer cylinder will not be used, causing this part of the washing Water is wasted, and the dirt generated during the washing process will accumulate as the water flows between the inner cylinder and the outer cylinder. With long-term use, the accumulation of dirt will affect the washing effect and reduce the user experience. [0003] In or...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned invention provides a drum washing machine with a non-porous inner cylinder, which solves the problems of wasting water between the inner cylinder and the outer cylinder and accumulation of dirt between the inner cylinder and the outer cylinder, however, only the existing drum washing machine The inner cylinder is designed as a non-porous structure, which has little practical significance. Since the inner cylinder needs to be rotated for washing, dehydration, and water storage, how to realize the drainage of the washing machine with a non-porous inner cylinder becomes the problem faced by the non-porous inner cylinder. primary problem
