FULLY AUTOMATIC PROTECTOR FOR REFRIGERATOR

The utility model belongs to an electric appliance type and is used for the over-voltage protection and the low-voltage protection of a refrigerator. The utility model aims to solve the problems of how to shut a freezing machine under the over voltage and the low voltage and how to automatically start the freezing machine when the power supply is restores, particularly the problem of return difference and the instant falling of the input voltage. The utility model adopts a parallel resistor, a divider circuit and a delay circuit to solve the problem of return difference and the instant falling of the input voltage. The utility model is used for refrigerators to completely automatically protect the refrigerator from the damage caused by the voltage fluctuation, without misoperation.
