Title:
EVAPORATOR AND REFRIGERATOR COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2017/164533
Kind Code:
A1
Abstract:
Disclosed is a refrigerator comprising a cabinet in which a freezing compartment and a refrigerating compartment are vertically provided; and an evaporator installed in the freezing compartment, wherein the evaporator comprises: an evaporator case which is formed in the form of a hollow box of which both sides are open, and has a food storage space formed therein; a cooling tube which is formed in the evaporator case in a predetermined pattern, and in which a coolant for cooling is charged; and a sheath heater which is disposed on the outside of the evaporator case to be adjacent to at least one surface of the evaporator case, and when power is applied, generates heat such that the heat for defrosting is transferred to the evaporator case. The present invention reduces the defrosting time compared to the existing natural defrosting and thus can maintain the freshness of food, and increases the cooling efficiency which was decreased due to frost, and thus can reduce power consumption. Further, the defrosting efficiency by the sheath heater can be improved by a reflection member, and an inflow of heat, generated when defrosting, into the refrigerating compartment can be prevented by a heat insulation member.
