Abstract
A defroster for refrigerators, capable of defrosting both a prefrosting panel and an evaporator using a defrosting heater, is disclosed. In an embodiment, a heat conduction panel integrally extends from the defrosting heater and terminates at a position approximate to one end of the prefrosting panel, thus allowing heat of the defrosting heater to be transferred to the prefrosting panel through thermal conduction. The heat conduction panel has an enough width to be connected to the total length of the defrosting heater and is uniformly spaced apart from the end of the prefrosting panel. In another embodiment, the prefrosting panel extends to an enough length to be directly connected to the defrosting heater, thus being selectively defrosted with heat transferred from the defrosting heater through thermal conduction.
