Control method of washing machine

Abstract

A control method of a washing machine, capable of suppressing the generation of vibration and noise caused by the eccentricity of the washing tub, and effectively avoiding the delay of the running time. The control method of the washing machine (1) of the present invention includes in the dehydration process: an unbalanced position detection step (SP8), detecting the unbalanced position (N); a balancer selection step (SP10), determining the baffle plate (7) that needs to be filled with water ); the first water injection step (SP11), when at least two baffles (7) need to be filled with water, the baffle (7) that is farthest from the unbalanced position (N) is injected to adjust the water; an unbalanced amount detection step (SP12) of detecting the evolution of the unbalanced amount (M) of the washing tub; and a water injection switching step (SP18) of turning up the unbalanced amount (M) detected by the unbalanced amount detection step (SP12) , switch the water injection from the water supply valve (X) to the water supply valve (Z).

Description

technical field [0001] The invention relates to a control method of a washing machine, which can eliminate the unbalance of the washing bucket during the dehydration process, and suppress the vibration and noise caused by the eccentricity of the washing bucket during the dehydration. Background technique [0002] Ordinary washing machines installed in ordinary households or self-service laundry rooms, etc., generate vibration and noise due to deviation of the laundry in the dehydration tub during dehydration. This vibration and noise may develop into trouble depending on the installation place and surrounding environment of the washing machine. In addition, when the laundry is unevenly distributed at this time, the eccentricity of the washing tub during rotation is large, and a large torque is required for rotation, so the spin-drying operation cannot be started. [0003] Therefore, Patent Document 1 discloses a technique of detecting the unbalanced amount and unbalanced po...

AI Technical Summary

Problems solved by technology

[0005] However, in the structure disclosed in Patent Document 1, unbalance detection and dispersion operations can only be performed when the dehydration tub rotates at a low speed during the dehydration process. unbalanced

[0006] In addition, in the structures disclosed in the above-mentioned Patent Documents 1 and 2, since the rotation of the spin-drying tub is decelerated or stopped when an imbalance is detected, starting power is required every time the spin-drying operation is repeated. The time required for washing, that is, the problem of running time delay

Furthermore, in Patent Document 2, in addition to the increase in power consumption, there is also a problem of an increase in water consumption

[0007] And, especially for the washing machine installed in the self-service laundry room, the delay of the above-mentioned operation time will lead to the reduction of customer circulation efficiency in the store.
