Outage time -delayed protection ware of refrigerator

The utility model discloses an outage time -delayed protection ware of refrigerator, it needs, and the manual work is direct inserts supply socket with the plug, just can confirm to postpone the time of switch on according to the power off time length of refrigerator, and insert supply socket with the plug again after need not artifical calculation delay time, and it is very convenient to use. It includes that power transformer rectification filter circuit, current potential control circuit, sampling circuit, bidirectional thyristor trigger control circuit, refrigerator drive circuit, the input voltage of power loops through the current potential state that power transformer rectification filter circuit, sampling circuit, current potential control circuit obtained output current potential point, and when output current potential point during for the low level, the bidirectional thyristor triggers control circuit out of work and do not drive refrigerator drive circuit, and when output current potential point w
