  • Patent number: 7458230
    Abstract: A refrigerator is provided with an airflow passage for an ice making compartment of the refrigerator. In the refrigerator, a main body has an opened side, and a door selectively closes the opened side of the main body. An ice making compartment is formed in the door, the ice making compartment being insulated from the outside and being kept at a low temperature. A duct is formed in the main body for exchanging cooling air with the ice making compartment, and a cooling air passage is formed at an outer surface of the ice making compartment to connect the duct with the ice making compartment. A switching unit closes the cooling air passage when the door is opened, and opens the cooling air passage when the door is closed. With this arrangement, the cooling air can be sufficiently supplied to the ice making compartment without the penetration of foreign substance.
