Dehydration control method and device of washing machine and washing machine

Abstract

The present invention provides a dehydration control method, device and washing machine for a washing machine, wherein the method includes: during the dehydration process of the washing machine, real-time collection of operation data at the current rotational speed gear, wherein the operation data includes the current rotational speed of the motor in the washing machine and According to the current current, according to the operating data, it is judged whether it is allowed to increase the speed from the current speed gear to the target speed gear. If the judgment result is yes, increase the speed so that the speed is in the target speed gear. Since the load driven by the motor affects the current of the motor, the method realizes that the speed of the motor is increased step by step according to the load condition, which improves the dehydration effect, and solves the problem that the existing washing machine runs according to the set rhythm, resulting in poor dehydration effect. good question.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a dehydration control method and device for a washing machine and a washing machine. Background technique [0002] During the dehydration process of the washing machine, excessive load, poor drainage, excessive detergent input and excessive foam will cause excessive dehydration resistance, affect the motor speed, and then affect the dehydration effect. [0003] The existing solution is to prolong the dehydration time in the early stage and low speed as much as possible when designing the dehydration sequence, so that the water and foam of the clothes in the bucket can be discharged as much as possible, and the dehydration load of the motor can be reduced. However, the existing solution has the problem that the washing machine cannot adjust the dehydration sequence according to the load condition, and can only run according to the set rhythm, resulting in poor dehydra...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the first object of the present invention is to propose a dehydration control method for a washing machine. During the dehydration process, the current speed and current current of the motor are collected in real time, and whether to increase the speed gear of the motor is determined according to the operating data, so as to realize According to the load in the bucket, the motor speed is increased step by step to achieve efficient and fast dehydration, so as to solve the problem that the existing washing machine can only run according to the set rhythm, resulting in poor dehydration effect
