Abstract
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.
