ABSTRACT:
A refrigerator which has a device for opening/closing cool air discharge ports is disclosed. The device includes plates for opening/closing the ports, and a driving device for driving the plates. The heat exchange between an evaporator and the outside warm air is prevented during the defrosting operation when a door is open. Hence the cooling efficiency is enhanced and the frost caused by the outside warm air is not generated on the evaporater.
