ABSTRACT:
A refrigerator having a shutting device for preventing flow of air between an evaporator and a fresh food compartment is disclosed. The shutting device has a shutting member for shutting a space that the evaporator is installed against a cooling compartment, and a motor for driving the shutting member. During a defrosting operation and when the door is open, cool air discharge ports are closed by the shutting member. Thus, the temperature rise of the fresh food compartment due to the heat from a defrosting heater, and the loss of cool air and the generation of frost on the evaporator due to the opening of the door are prevented.
