Refrigerator and compressor control system thereof

Abstract

The invention provides a refrigerator and a compressor control system thereof. The control system comprises an inverter compressor, a temperature detection module, a control panel and a frequency controller, wherein the temperature detection module is used for detecting the chamber temperature of the refrigerator so as to generate a chamber temperature detection signal; the control panel is arranged on a refrigerator body of the refrigerator and further used for receiving refrigeration demand information input by users; and the frequency controller is connected with the temperature detection module, the control panel and the inverter compressor, and the frequency controller can further control the operative condition of the inverter compressor according to the chamber temperature detectionsignal and the refrigeration demand information so that the chamber temperature of the refrigerator can meet the requirement of the refrigeration demand information. According to the compressor control system of the refrigerator in the embodiment of the invention, frequency converting control can be realized on the refrigerator without a main control panel; and meanwhile, the refrigerator temperature can be controlled quickly and accurately in accordance with the chamber temperature of the refrigerator and the refrigeration demand information, and refrigeration performance and energy efficiency of the refrigerator can be better improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator and a compressor control system thereof. Background technique [0002] With the implementation of national standards for mandatory energy efficiency ratings for household refrigerators, the demand for improved energy efficiency ratings for refrigerators has become increasingly strong. The frequency conversion compressor adopting the frequency conversion control technology has great advantages in terms of energy saving, so it is more and more widely used in refrigerators. However, for the existing fixed-speed refrigerator without a main control board, it needs to invest a large cost to change the existing structure and electrical structure, and add a main control board to adapt to the inverter compressor. [0003] At present, the frequency conversion scheme in the related art usually uses the mechanical thermostat on the refrigerator, and sends the on ...

AI Technical Summary

Problems solved by technology

However, the problem with related technologies is that, on the one hand, the mechanical thermostat can only provide switching signals, and the variable speed adjustment of the compressor is realized by the control logic of the variable frequency controller itself, so it is impossible to quickly and accurately control the temperature of the refrigerator; On the one hand, the mechanical thermostat is connected to the mains power supply, and its opening and closing will bring certain electromagnetic interference.
