Claims

[Scope of utility model registration request]

It is equipped with a fan that circulates the air inside the refrigerator, an indirect cooling evaporator that cools the circulating air, and a direct cooling evaporator that is disposed inside the refrigerator from which the cooling air is blown out, and a refrigerant is supplied to the direct cooling evaporator. The device is equipped with a quick freezing switch that forms a current supply circuit and a defrosting heater that defrosts the indirect cooling evaporator, and is energized by the quick freezing switch when the quick freezing switch is activated to cool and freeze the liquid. A first relay is provided that allows the defrosting heater to continue its operation while cutting off the energization circuit of the defrosting heater, and is also energized when the defrosting heater is energized to continue energizing the defrosting heater. A refrigerator characterized by being provided with a second relay that cuts off the energized circuit that the switch closes.
