Patent ID: 11098944

Abstract:
A refrigerator includes a cabinet that defines a freezing compartment and a refrigerating compartment, and an evaporator installed in the freezing compartment. The evaporator includes: an evaporator case that defines a food storage space formed therein; a cooling tube located at the evaporator case in a predetermined pattern and configured to receive a coolant; and a sheath heater disposed outside of the evaporator case to be adjacent to at least one surface of the evaporator case, the sheath heater being configured to generate heat such that heat for defrosting is transferred to the evaporator case. The sheath heater reduces the defrosting time to maintain the freshness of food, increases the cooling efficiency, and reduces power consumption. The defrosting efficiency by the sheath heater is improved by a reflection member, and an inflow of heat, generated when defrosting, into the refrigerating compartment is reduced by a heat insulation member.
