AI Technical Summary

Technical Problem

In the existing technology, an improperly set pre-positioning angle or an inappropriate starting current can affect the starting of the refrigerator compressor, and troubleshooting is difficult.

Method used

By acquiring the first and second preset angles, it is determined whether the current slope has reached the preset value. The compressor is then controlled to start with an increased current value, and the color and frequency of the indicator light flashing are used to prompt the engineer to adjust the angle and optimize the startup process.

Benefits of technology

This allows for rational and scientific control of compressor startup, extending its service life and improving the convenience and accuracy of fault diagnosis.

Abstract

The application provides a control method of a refrigerator compressor and a refrigerator. The control method of the refrigerator compressor comprises the following steps: obtaining a first preset angle and a second preset angle when a starting condition of the compressor is met; electrifying a first preset value of current at the first preset angle of a stator winding coil of the compressor; judging whether the first preset angle meets a first condition; if yes, electrifying a second preset value of current at the second preset angle of the stator winding coil; judging whether the second preset angle meets a second condition; and if yes, controlling the compressor to start with a third preset value of current, wherein the first preset value, the second preset value and the third preset value increase in sequence. According to the scheme, the starting of the refrigerator compressor can be reasonably and scientifically controlled, and the service life of the refrigerator compressor is prolonged.
