Abstract
The present invention relates to a defroster, and more particularly, to a defroster in a refrigerator in which a damper mounted to an inlet to a circulating duct (60) controls air to flow in a reverse direction toward an evaporator (20) for maximizing defrosting efficiency by using not only radiant heat but also convective heat. For this, the defroster in a refrigerator includes an evaporator (20), a heater (10) for defrosting the evaporator (20) by radiation, and flow control means (50) for controlling air circulated by a fan (30) to flow in a reverse direction toward the evaporator (20) in the defrosting.
Claims8
A defroster in a refrigerator comprising:
- an evaporator;
- a heater for defrosting the evaporator by radiation;
- and
- flow control means for controlling air circulated by a fan to flow in a reverse direction toward the evaporator in the defrosting.
The defroster as claimed in claim 2, wherein the flow control means is a damper mounted to an inlet to the circulating duct having cold air circulated therethrough.
A defroster in a refrigerator comprising:
- a cold air supply portion having an evaporator and a fan mounted therein;
- a heater for defrosting the evaporator by radiation;
- a circulating duct for guiding cold air from the cold air supply portion to a refrigerating chamber and/or a freezing chamber;
- and
- flow control means mounted to the circulating duct so that air flows in a reverse direction from the air supply portion toward the evaporator by the fan in the defrosting.
