ABSTRACT:
A concentrated cool air supply device for refrigerators is disclosed. In the device, a branch duct is branched from the cool air passage to guide the cool air to the door. A door duct is formed on the door to receive the cool air from the branch duct. The door duct has a plurality of air outlet openings on a cover plate. The outlet openings of the door duct are selectively opened by a slide panel, thus concentrically discharging the cool air from the door duct into a desired portion of the compartment. In order to move the slide panel, the device also has a motor, a rotatable link and a connecting rod. The link is coupled to the motor, thus being selectively rotated by the motor, while the connecting rod is connected to the link and the slide panel at both ends.
