ABSTRACT:
A refrigerator having an apparatus for defrosting. The refrigerator provides an apparatus for defrosting which uses a wasted heat from a compressor. The apparatus has a container placed on an upper surface of the compressor and an antifreezer solution for absorbing and storing the wasted heat from the compressor by performing a heat exchange. A pipe and a pump for circulating the fluid via a space section is provided. In the space section, the pipe is formed with a bending portion so as to transfer a heat to a surrounding air. In addition, a valve for preventing a high temperature air from flowing into a freezer compartment while a defrost operation is being carried out, and a plate for preventing a cabinet from being melted are provided. The refrigerator according to the present invention can carry out a defrost operation by both heater and a wasted heat of a compressor, thereby reducing the power consumption thereof and reducing the time required for the defrost operation, and also provide a valve for preventing an air with high temperature from flowing into a freezer compartment, thereby preventing the temperature of the freezer compartment from being raised.
