Method for controlling motor, frequency converter and clothes processing device

Abstract

Embodiments of the present invention provide a method for controlling a motor, a frequency converter, and a clothes processing device, which belong to the field of household appliances. The method includes: receiving a start instruction; and controlling the start of the motor according to the start instruction, recording the action time of the motor after the start of the motor, and controlling the start of the motor according to the relationship between the action time and a preset time start or stop. The frequency converter is used in a clothes treatment device, and the frequency converter includes: a communication module, used to receive a starting command; a timing module, used to record the action time of the motor in the clothes treatment device; and a control module, used to: The start command controls the start of the motor; and controls the start or stop of the motor according to the relationship between the action time and the preset time. The laundry processing device includes the frequency converter described above. Thereby, the stop time of the motor is shortened, the effective time of washing clothes by the clothes treating device is increased, and the washing efficiency is improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a method for controlling a motor, a frequency converter and a clothes processing device. Background technique [0002] With the increasingly higher requirements for energy saving and noise in the market, variable frequency motors are widely used in washing machines. At present, most of the mainstream washing machines on the market are frequency conversion, which saves more than 30% of electricity and reduces noise by more than 25% compared with non-inverter washing machines under the same conditions. At present, the control method of the frequency conversion washing machine (especially the pulsator washing machine) is that the main control module of the washing machine transmits commands to the frequency converter, and the frequency converter controls the motor according to the commands. Compared with non-inverter washing machines, inverter washing machines have the problem t...

AI Technical Summary

Problems solved by technology

The main reason for this situation is that the main control module controls the motor through the frequency converter, and the communication time is too long.

This problem is reflected in the washing machine, which shows that the washing machine is unable to wash, the effective time of washing is insufficient, and the laundry is not clean, etc.
