Abstract: An evaporator includes: an evaporator case that defines a food storage space therein; a cooling tube located at the evaporator case and filled with refrigerant; a foil heater attached to at least one surface of the evaporator case and configured to contact the evaporator case and to generate heat such that heat for defrosting is transferred to the evaporator case. A defrosting time is reduced in comparison to that of conventional natural defrosting, such that the freshness of food can be maintained, and the cooling efficiency, having been reduced by frost, is increased such that power consumption can be reduced. The foil heater is attached to a conventional roll-bond type evaporator case, and the present invention has an advantageous effect of facilitating the maintenance of the foil heater because of a structure in which the foil heater is attached to the evaporator case.

Abstract: A dryer having a waste heat recovery device includes a cabinet, a drum rotatably mounted within the cabinet and having a front surface and a rear surface, an intake duct configured to provide an intake flow path through which air flows into the drum, an exhaust duct configured to exhaust air coming from the drum out of the cabinet, a heater configured to heat air flowing into the drum, and an ambient air duct configured to inhale air from outside the cabinet and supply the air from outside the cabinet into the drum. The waste heat recovery device includes an evaporation unit configured to absorb heat from air that is exhausted from the drum, a condenser unit configured to transfer heat absorbed from the evaporation unit to ambient air that flows into the ambient air duct, and a heat transfer medium configured to transfer heat between the evaporation unit and the condenser unit. The ambient air duct is configured to communicate air from the ambient air duct into the intake duct at a point along a flow path between the drum and the heater.

Abstract: A defrosting device includes a heating unit filled with a working fluid and including an active heating part heated to a first temperature that can evaporate the working fluid, and a passive heating part positioned at a rear side of the active heating part and heated to a lower temperature than the first temperature. The defrosting device also includes a heat pipe disposed adjacent to an evaporator to transfer heat to the evaporator while circulating working fluid heated by the active heating part, the heat pipe including an entrance portion configured to receive working fluid evaporated by the active heating part, and a return portion connected adjacent to the passive heating part and configured to receive working fluid that has condensed after circulating through the heat pipe. Condensed working fluid received at the heating unit first passes through the passive heating part before being reheated at the active heating part.
