ABSTRACT:
A refrigerator having a cabinet defining a first compartment and a second compartment separated from each other by a divider wall wherein the divider wall has an air passage for communicating between the first and second compartments. A baffle is positioned within the air passage and is positionable in an open or closed position for selectively opening and closing the air passage. A motor drives a cam which is coupled to the baffle such that rotation of the cam operates to selectively move the baffle to the open or closed position. A thermostat senses temperature within the fresh food compartment. First and second switches selectively energize the motor such that the baffle may be opened when the thermostat indicates the fresh food compartment requires cooling and closed when the thermostat indicates the fresh food compartment does not require cooling, respectively. The baffle of the present invention further includes a first plate having an aperture therethrough defining an opening through which refrigerated air may pass, and a second plate movable relative to the first plate and including an aperture therethrough defining an opening through which refrigerated air may pass. Both the second plate and first plate aperture includes chamfered edges for forming a sharp edge periphery on the facing plate surfaces such that frost build up on the baffle may be removed by the chamfered edges provided on the periphery of the apertures.
