Abstract

A refrigerator, comprising a refrigerator body defining a first chamber and a door body. The door body comprises a main door for opening/closing the first chamber, and defining a second chamber, and a secondary door for opening/closing the second chamber. An air supply port for introducing air in the first chamber into the second chamber, and an air return port for returning air in the second chamber to the first chamber are provided on a rear wall of the main door. The second chamber is provided with a dry storage portion. The rear wall of the main door comprises a front shell and a rear shell with an air duct defined therebetween. The air duct introduces cold air prepared in the refrigerator, so that the cold air is condensed on an inner wall of the air duct, becomes dry gas, and then flows into the dry storage portion.
