An air flow control for a multi-port refrigerator duct that conveys cold air from the evaporator chamber to a plurality of storage chambers within the fresh food compartment. The duct has a baffle providing individual branches for each storage chamber such that each is substantially coupled directly to the evaporator chamber so that a change in air flow in one branch does not significantly affect the flow in the opposite branch. A manually operated control is mounted within the fresh food compartment and has a face plate with a vent aligned with a liner input aperture communicating with the duct. A shutter disc is captured between the face plate and the liner, and has a tear drop opening. Rotation of the shutter disc alters the location of the tear drop opening and, thus the size of the passageway through the air flow control.

Air flow control for multi-port refrigerator duct

Refrigerator duct apparatus adapted for conveying cold air from the evaporator chamber within the freezer liner to a intermediate temperature storage chamber within the fresh food liner. The duct is coupled to an outlet aperture in the freezer liner using and adjustable joint that permits motion of the duct for alignment of the outlet port of the duct to an inlet aperture in the fresh food liner. Specifically, the inlet port of the duct has a mating flange with ears that are insertable through the outlet aperture in the fresh food liner in a predetermined rotational orientation. After insertion, the duct is rotated so that the ears engage peripheral portions of the outlet aperture. A dimension of the outlet aperture is larger than a corresponding dimension of the mating flange to permit the duct to be moved back and forth while the ears remain in sliding engagement on the peripheral portions to align the duct outlet port to the inlet aperture of the fresh food liner.
