摘要： The present invention discloses a defrost apparatus of a refrigerator which can defrost an evaporator by a defrost heater, when moisture of the ambient air of the evaporator is frozen on the surface of the evaporator. The defrost apparatus of the refrigerator includes a pair of evaporators and a pair of defrost heaters to selectively defrost the pair of evaporators. A path varying means for guiding air flow is installed near the pair of evaporators. The air is not supplied to the defrosted evaporator, for performing the defrosting operation. The air is supplied to the non-defrosted evaporator, for performing the cooling operation. As a result, the defrosting operation is efficiently performed, and the temperature does not sharply increase in freezing and refrigerating chambers, so that the food can be maintained fresh for an extended period of time.
