Abstract

The invention provides a method and device for controlling a variable frequency compressor and a refrigerator. The method includes: storing discharge models and protection voltages of various power supply batteries; detecting the voltage of the external power supply of the refrigerator in real time; determining the power supply according to the detected voltage The voltage change of the voltage of the power supply within a certain period of time; the voltage change is that when the voltage shows a downward trend with time, according to the detected voltage and combined with the stored discharge model, determine the battery type of the power supply; it will meet the battery type The protection voltage of the power supply battery is determined as the protection voltage of the power supply; it is judged whether the detected voltage is not greater than the protection voltage of the power supply, and if so, the inverter compressor in the refrigerator is controlled to stop working. The change of the power supply is determined by detecting the voltage, and the protection voltage is correspondingly changed when the battery is used for power supply, so that the compressor can be stopped when the voltage is not greater than the protection voltage. The scheme can automatically and accurately set the protection voltage.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for controlling a variable frequency compressor and a refrigerator. Background technique [0002] Portable refrigerators on the market, such as the more common car refrigerators, are favored by users because they are mobile and easy to carry. [0003] Currently, users can set the protection voltage according to the type of external power supply used. For example, the protection voltage is usually divided into three fixed levels, and the user can choose the level independently according to the different power supply types used. Based on this, the control system board in the refrigerator can control the operation of the inverter compressor in the refrigerator according to the cooling temperature set by the user, the ambient temperature of the refrigerator, and the temperature of the inner compartment of the refrigerator, and monitor the external power supply ...
