摘要： Provide is a refrigerator provided with a defrosting device capable of enhancing the defrosting efficiency. The refrigerator includes main body, storage compartment provided inside the main body, an evaporator provided in the storage compartment and configured to generate cold air, a first flow path allowing air to be guided in a first direction for the air to be supplied to the storage compartment during a cooling operation, a defrosting heater configured to generate heat for defrost, a second flow path allowing air to be guided in a second direction opposite to the first direction for the air to be circulated around the evaporator during a defrosting operation, a fan allowing air having received heat from the defrosting heater to be circuited around the evaporator through the second flow path, and a flow path resistance portion provided on the second flow path to increase a flow path resistance in the first direction.

摘要： Disclosed herein is a refrigerator. The refrigerator includes a refrigerating compartment that is divided into a refrigerating section formed on an upper side thereof and an alternate temperature section formed on a lower side thereof, a cold air supply unit that includes a cold air flow path formed on a rear side of the refrigerating compartment and a refrigerating compartment circulation fan for allowing cold air of the cold air flow path to flow, and a control unit that controls the refrigerating compartment circulation fan. Here, the control unit cools the refrigerating section by turning on the refrigerating compartment circulation fan, and causes deflection of the cold air of the cold air flow path to cool the alternate temperature section by turning off the refrigerating compartment circulation fan.
