  • Patent number: 6318099
    Abstract: A cooling air distributing structure for refrigerators is disclosed. The cooling air distributing structure for refrigerators has a grille panel. The grille panel defines the rear wall of the freezer compartment. The grille panel has a cooling air passageway connected to the refrigerator compartment at its lower end and is provided with a cooling air outlet for discharging a cooling air to the freezer compartment. A cooling air regulator controls a cooling air supply to the refrigerator and is mounted near to the cooling air outlet. In another embodiment, the cooling air passageway may consist of a protrusion formed by projecting a middle portion of the grille panel, and a cover plate covering the rear of the protrusion.
