Problems solved by technology

[0004] However, most of the above-mentioned eccentricity detections are realized by motor signal feedback. This method cannot accurately determine the eccentricity due to the influence of the total weight of the load. Once the detection is wrong, the risk of the drum washing machine’s outer tub hitting the casing during dehydration acceleration will be great.

Abstract

The invention discloses a washing machine control method, a device, a machine-readable storage medium and a drum washing machine. The control method includes the steps of: S0: detecting the vibration of the drum washing machine (100) through an eccentricity detection bridge circuit (5), wherein the At least one bridge arm resistance in the eccentricity detection bridge circuit (5) is a resistive strain gauge sensor (4); S1: obtain the voltage signal of the bridge circuit output terminal (51) of the eccentricity detection bridge circuit (5) , the voltage signal characterizes the magnitude of the vibration of the drum washing machine (100); S2: Determine the detection result of the eccentricity of the laundry distribution in the drum washing machine (100) according to the fluctuation value of the voltage signal and a preset fluctuation threshold . The control method of the invention is novel, can realize stable, high-precision detection and control of the eccentricity of the washing machine, and has low cost.

Description

technical field [0001] The present invention relates to the technical field of washing machines, and in particular, to a control method and device for a washing machine, a machine-readable storage medium, and a drum washing machine. Background technique [0002] In a drum washing machine, when the drum is unbalanced, the higher the speed of the variable frequency motor, the greater the vibration and noise of the system, which will reduce the service life of the drum washing machine. [0003] like figure 1 As shown, the inside of the drum washing machine is a multi-degree-of-freedom suspension system. When the clothes are not evenly distributed during dehydration, eccentricity will occur. The internal system is in a multi-directional swing state. The greater the risk of the case. In order to ensure the safe operation of the dehydration of the front-loading washing machine, most of the front-loading washing machines are equipped with an eccentricity detection function. For ...
