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 control method and device of a washing machine, a machine readable storage medium and the washing machine. The control method comprises the following steps that S0, vibrationof the washing machine (100) is detected through an eccentricity detection bridge circuit (5), wherein at least one bridge arm resistor in the eccentricity detection bridge circuit (5) is a resistivestrain gauge sensor (4); S1, a voltage signal of the bridge circuit output end (51) of the eccentricity detection bridge circuit (5) is acquired, wherein the voltage signal characterizes the magnitude of vibration of the washing machine (100); and S2, a detection result of distribution eccentricity of clothes in the washing machine (100) is determined according to a fluctuation value of the voltage signal and a preset fluctuation threshold. A control mode is novel, stable and high-precision detection and control of eccentricity of the washing machine can be realized, and the cost is relatively low.

Description

technical field [0001] The present invention relates to the technical field of washing machines, in particular to a washing machine control method, device, machine-readable storage medium and washing machine. Background technique [0002] In the drum washing machine, when the drum is unbalanced, the higher the speed of the frequency conversion motor, the greater the vibration and noise of the system, which will reduce the service life of the drum washing machine. [0003] Such as 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 state of multi-directional swing. 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 example, the f...
