Washing machine motor detection method and washing machine

Abstract

The invention relates to the technical field of household appliances, in particular to a washing machine motor detection method and a washing machine. The method comprises the following steps: obtaining a washing machine characteristic curve in a pre-delivery detection process of the washing machine; comparing whether the washing machine characteristic curve is deviated from a preset curve; and when the deviation exists, adjusting the rotating speed of a motor to eliminate the deviation. According to the method, the washing machine is detected before leaving a factory, and when the deviation exists between the obtained washing machine characteristic curve and the preset curve, the deviation can be eliminated through parameter compensation processing, so that the consistency requirement of the washing machine motor can be met, the washing machine does not generate abnormal sound or noise due to deviation of the motor in a working process after leaving the factory, the energy consumption and the use efficiency of each washing machine leaving the factory are ensured to be consistent, and a maintainer can quickly check the reason of the abnormal sound in a maintenance process after the washing machine leaves the factory.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine motor detection method and a washing machine. Background technique [0002] After the general motor of the existing washing machine is installed on the whole machine, there are individual differences among the motors of the same type, such as the difference in the magnetization amount of the frequency conversion DDM motor, the individual difference in the magnetic steel, the difference in the number of turns of the ordinary asynchronous motor coil, and the difference in the inner diameter of the coil. Effective detection cannot meet the consistent use requirements of the motor. At the same time, due to individual differences in the motors after leaving the factory, there will be risks in the use of washing machines, such as: noise, abnormal sound, direct deviation of washing curve and dehydration curve, affecting the energy consumption of the whole ...

Problems solved by technology

[0002] After the general motor of the existing washing machine is installed on the whole machine, due to the individual differences among the motors of the same type, such as the difference in the magnetization amount of the frequency conversion DDM motor, the individual difference in the magnetic steel, the difference in the number of coil turns of the ordinary asynchronous motor, and the difference in the inner diameter of the coil, etc., it is impossible to Effective detection cannot meet the consistent use requirements of motors

At the same time, due to the individual differences of the motor after leaving the factory, there will be risks in the use of the washing machine, such as: noise, abnormal sound, direct deviation of the washing curve and dehydration curve, affecting the energy consumption of the whole machine, and reducing the use efficiency, etc.
