Drum washing machine and eccentricity detection control method and system when washing machine conducts dewatering

Abstract

The invention discloses a drum washing machine and an eccentricity detection control method and system when the washing machine conducts dewatering. The method comprises the steps of controlling a dewatering motor to run at a first accelerated speed when the drum washing machine executes a dewatering program, maintaining the speed for a first duration after the rotating speed reaches a first rotating speed, and controlling the dewatering motor to run at a second accelerated speed after the first duration is reached until the rotating speed of the dewatering motor reaches a second rotating speed; detecting the rotating speed of a dewatering drum within the first duration, and obtaining the rotating speed difference value between the maximal rotating speed and the minimum rotating speed of the dewatering drum within the first duration; obtaining the accumulated input power when the first rotating speed of the dewatering motor is increased to a preset rotating speed from the first rotating speed; judging the eccentricity condition of the drum washing machine according to the rotating speed difference value and the accumulated input power, and controlling the dewatering motor accordingto the eccentricity condition. Therefore, by means of the drum washing machine and the eccentricity detection control method and system, the impact on the dewatering drum during accelerated dewatering can be reduced or avoided, and the user experience is improved. The invention further provides a non-temporary 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] Since the inside of the drum washing machine is a multi-degree-of-freedom suspension system, uneven distribution of clothes during dehydration will cause eccentricity, and the internal system is in a multi-directional swing state. The greater the eccentricity, the higher the operating speed and the greater the swing. The greater the risk of the shell. 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.

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
