摘要

PURPOSE: A defrosting device using a flat heater with a heating strip is provided to increase defrosting efficiency using a pair of flat heaters. CONSTITUTION: A defrosting device comprises a pair of front defrosting heater(30a) and rear defrosting heater(30b). The front defrosting heater and the rear defrosting heater are arranged on the front side and rear side of an evaporator to be contacted with a heat radiation fin. Each defrosting heater comprises a heating strip(33), a substrate(31) for heat transmission, a first insulation layer(32), and a second insulation layer(34). When a power source is applied to both ends of the heating strip, the heating strip radiates heat.
