ABSTRACT:
A cool air supplying apparatus capable of dispersedly supplying cool air into the refrigerator by use of a swing plate disposed within a cool duct is disclosed. The cool duct comprises a main duct extending through a freezing room and a refrigerating room and at least one sub-duct communicated with the main duct and having a plurality of holes for supplying the cool air. The swing plate is disposed within the sub-duct along its longitudinal direction. A shaft is disposed within the main duct to be capable of reciprocating along its longitudinal direction and is operatively connected with the swing plate. A motor is installed at an upper portion of the main duct, and a crank is operatively connected with each of a rotary shaft of the motor and the shaft. The shaft and the swing plate are operatively connected with each other by means of a protrusion formed at a long side of the swing plate and having an U-shaped groove through which the shaft passes and pairs of collars fixed on the shaft to insert the protrusion therebetween.
