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.

Refrigerator

A refrigerator includes a storage compartment; a first flow path separated from the storage compartment; an evaporator provided on the first flow path to cool air; a compressor configured to discharge a refrigerant to the evaporator; a blower fan configured to discharge air of the first flow path to the storage compartment; a defrost heater provided on the first flow path to heat the evaporator; a second flow path separated from the first flow path; a defrost fan configured to suction air of the first flow path into the second flow path; and a controller configured to alternately perform a cooling operation and a defrosting operation, configured to operate the compressor and the blower fan during the cooling operation, configured to operate the defrost heater and the defrost fan during the defrosting operation, and configured to vary a rotational speed of the defrost fan.

Refrigerator and controlling method thereof

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.
