Abstract
A refrigerator is provided that includes a cold air duct that receives cold air circulating inside of a refrigerating chamber and a freezing chamber, an evaporator in the cold air duct, at least one defrosting heater in the cold air duct that selectively emits heat, a fan in the cold air duct, that selectively directs the cold air in an upward or downward direction, a motor that drives the fan, and an open/close device that closes a space having the evaporator, the defrosting heater, and the fan positioned therein selectively, thereby providing an improved defroster for an evaporator.
