The invention provides an inverter compressor control method, an inverter compressor control device and a refrigerator. The inverter compressor control method comprises the following steps of storingdischarge models and protecting voltages of various power supply batteries; detecting the voltage of an external power supply of the refrigerator; determining the voltage change condition of the voltage of the power supply within a certain period of time; when the voltage change condition is that the voltage decreases as time is prolonged, determining the battery type of the power supply by combining the stored discharge models according to the detected voltage; determining the protecting voltage of the power supply battery which meets the battery type as the protecting voltage of the power supply; and judging whether the detected voltage is not greater than the protecting voltage of the power supply or not, and if so, controlling an inverter compressor in the refrigerator to stop working.By detecting the voltage to determine change of the power supply and changing the protecting voltage correspondingly when the battery is used to supply power, the compressor can be stopped when the voltage is not greater than the protecting voltage. According to the scheme, the protecting voltages are set automatically and accurately.
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 ...
