  • Patent number: 11519659
    Abstract: Disclosed herein is a refrigerator. The refrigerator includes a body, a storage compartment disposed inside the body, an evaporator configured to generate cold air and disposed behind the storage compartment, and a duct configured to supply the cold air generated by the evaporator to the storage compartment. The duct includes a first discharge hole through which air flowing in the duct is discharged, a plurality of second discharge holes through which air is discharged at a speed lower than a speed of the air discharged through the first discharge hole, and a damper configured to selectively regulate a flow of air to guide the air in the duct to the first discharge hole or the plurality of second discharge holes.
