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.

Embodiment 1

[0027] Before the washing machine leaves the factory, it will carry out inspections such as empty bucket washing and empty bucket dehydration. The method provided in this example can be applied at this stage to avoid noise or abnormal sound after the washing machine leaves the factory due to motor problems, so that maintenance personnel can quickly troubleshoot the noise. or abnormal sound.

[0028] Such as figure 1 As shown, this embodiment provides a washing machine motor detection method, the method first obtains the washing machine characteristic curve in the washing machine factory inspection process, and then compares whether the washing machine characteristic curve deviates from the preset curve, and if there is a deviation, then the The motor speed is adjusted to eliminate the deviation.

[0029] In the present invention, testing is carried out before the washing machine leaves the factory, and when there is a deviation between the obtained washing machine characteris...

Embodiment 2

[0035] Such as figure 2 As shown, this embodiment provides a washing machine motor detection method. On the basis of Embodiment 1, it further limits the multiple motor speed adjustments to the washing machine characteristic curve. After each speed adjustment, the motor speed after adjustment The characteristic curve of the washing machine is compared with the preset curve. When the number of adjustments of the motor speed of the washing machine does not exceed the preset number of times, the new washing machine characteristic curve obtained after the motor speed adjustment can be compared with the preset curve, which avoids the motor speed value selected during the motor speed adjustment being within the preset range. , but when the motor speed value is too large or too small when the deviation is caused, it will directly prompt the operator of the motor failure, so as to avoid increasing the workload of the operator.

[0036] More specifically, if the characteristic curve o...

Embodiment 3

[0040] This embodiment provides a washing machine, and the motor used in the washing machine is tested at the factory using the above-mentioned detection method for the washing machine motor.

[0041] The washing machine of the present invention, by using the above method, can make the washing machine detect the characteristic curve of the motor when it leaves the factory, and make the characteristic curve of the motor consistent after the weighting process, so that the washing machine will not be affected by the presence of the motor in the working process after leaving the factory. Abnormal sound or noise due to deviation, to ensure that the energy consumption and use efficiency of each washing machine leaving the factory are consistent, and after the washing machine leaves the factory, the maintenance personnel can quickly check the cause of the abnormal sound during the maintenance process.

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 ...
