DEFROSTER OF REFRIGERATOR

摘要

PURPOSE: A defroster of a refrigerator is provided to remove frost using water vapor forcibly evaporated by operating heat of a compressor. CONSTITUTION: A solenoid valve(90) is periodically open and closed depending on the operation of a compressor(54). The solenoid is installed in the lower part of a spraying guider(80). By stopping the compressor, the solenoid opens the spraying guider. Then the part of defrosting water is forcibly evaporated by superheat and changed to large quantity of water vapor including superheat. Water vapor is suddenly sucked into the spraying guider and sprayed to the upside from the downside of a cooler(20). Then superheat included in water vapor is delivered on the surface of the cooler and frost is molten.
