Problems solved by technology
The state where the compressor stops working can be defined as the standby state. Although the frequency conversion control board in this state does not supply power to the compressor, it still consumes electric energy continuously because the single-chip microcomputer and other power devices are still working.
[0003] At present, when the compressor is in the standby state, the power consumption of the frequency conversion control board needs to be reduced

The invention discloses a refrigerator and a power consumption reduction control method and device for a variable-frequency control panel of a compressor of the refrigerator. The power consumption reduction control method comprises the following steps that a pulse signal sent by a master control panel of the refrigerator is obtained; whether the compressor enters a starting state or a standby state is judged according to the pulse signal; if the compressor enters the starting state, the system clock frequency of a master control chip in the variable-frequency control panel is controlled to be switched to a first frequency value; and if the compressor enters the standby state, the system clock frequency of the master control chip in the variable-frequency control panel is controlled to be switched to a second frequency value which is smaller than the first frequency value. According to the power consumption reduction control method, power consumption of the variable-frequency control panel can be reduced.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a power consumption reduction control method of a frequency conversion control board of a refrigerator compressor, a power consumption reduction control device of a frequency conversion control board of a refrigerator compressor, and a refrigerator. Background technique [0002] The compressor is the heart of the refrigeration system. The piston is driven by the motor to provide power for the refrigeration cycle, and the motor is driven by the frequency conversion control board. The work of the compressor is intermittent. When the temperature in the refrigerator is higher than the set temperature, the compressor will automatically start the refrigeration work. When the temperature in the refrigerator is lower than the set temperature, the compressor will automatically stop. , so that the cycle is repeated, and the start and stop of the compressor are controlled by...
