Date Dec. 7, 1995A refrigerator includes a refrigerating compartment and a cool air distributing system on the back wall thereof. The distributing system includes vertical passages which divide a flow of incoming cool air and conduct the air to vertically spaced discharge openings communicating with the refrigerating compartment. Disposed in the path of air flow is an air directing structure having adjustable vanes for controlling the horizontal direction in which the air flows enter the refrigerating compartment. Each vane is motor driven and can comprise vertical plates or helical elements rotated about a vertical axis. Alternatively, each vane can be a helical vane disposed on the inside surface of a hollow cylinder for guiding an air flow from within the cylinder outwardly through openings formed in a wall of the cylinder.
