ABSTRACT:
A refrigerator having a temperature controlled chamber partitioned from a refrigerator compartment and a freezer compartment. Air is circulated between the freezer compartment and the temperature controlled chamber through air inlet and outlet ports, thus cooling the temperature controlled chamber. An intake damper is installed in the air inlet port, and a fan is mounted at a rear portion of the temperature controlled chamber. The intake damper has a thin plate, thus opening the air inlet port in response to the air flowing into the temperature controlled chamber when the cooling fan is operated, and closing the air inlet port in response to a stoppage of flow of the air when the cooling fan stops. Further, a temperature sensor is mounted in the temperature controlled chamber to control operation of the fan, thus allowing an interior of the temperature controlled chamber to be maintained at a predetermined temperature.
