Abstract
A refrigerator having an intermediate storage compartment, which has an improved structure of a return flow passage to return cold air from the intermediate storage compartment. The refrigerator includes a first evaporator to supply cold air to an upper storage compartment, a second evaporator to supply cold air to a lower storage compartment, a cold air supply duct to supply cold air generated at the second evaporator to an intermediate storage compartment, and a curved section formed at a top of the intermediate storage compartment to uniformly distribute the cold air supplied via the cold air supply duct in the intermediate storage compartment. The refrigerator also includes a cold air return duct to return cold air from the intermediate storage compartment, and an ice-making cold air return duct to return cold air from an ice maker. The cold air return duct is joined with the ice-making cold air return duct.
