Drum washing machine and eccentricity detection control method and system during dehydration

Abstract

The invention discloses a drum washing machine and an eccentricity detection control method and system during dehydration thereof, wherein the method includes: when the drum washing machine executes a dehydration program, controlling the dehydration motor to accelerate at a first acceleration until the rotation speed reaches the first rotation speed Then maintain the first time, after the first time, control the dehydration motor to accelerate with the second acceleration until the speed of the dehydration motor reaches the second speed; detect the speed of the dehydration bucket in the first time, and obtain the dehydration bucket The speed difference between the maximum speed and the minimum speed; obtain the cumulative input power of the dehydration motor when it rises from the first speed to the preset speed; judge the eccentricity of the drum washing machine according to the speed difference and the cumulative input power, and according to the eccentricity Control the dehydration motor. Thus, the impact of the dehydration bucket during accelerated dehydration can be reduced or avoided, thereby improving user experience. The present invention also proposes a non-transitory computer-readable storage medium.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to an eccentricity detection and control method during dehydration of a drum washing machine, a non-transitory computer-readable storage medium, an eccentricity detection and control system during dehydration of a drum washing machine, and a drum washing machine. Background technique [0002] Because the inside of the drum washing machine is a multi-degree-of-freedom suspension system, the uneven distribution of clothes during dehydration will cause eccentricity, and the internal system is in a multi-directional swing state. The greater the risk of the shell. In order to ensure the safe operation of the dehydration of the front-loading washing machine, most front-loading washing machines are equipped with the eccentricity detection function, but it is generally realized at a low speed and steady state. This method is affected by the load and cannot accurately locate the ecc...

Problems solved by technology

In order to ensure the safe operation of the dehydration of the front-loading washing machine, most of the front-loading washing machines have an eccentricity detection function, but it is generally realized at a low-speed steady state. This method is affected by the load and cannot accurately locate the eccentricity. After the low-speed detection is over, the secondary detection and judgment cannot be performed under the accelerated state, and there is a risk of the dehydration bucket hitting the box shell
