ABSTRACT:
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.
