ABSTRACT:
A refrigerator having a crisper pan with a back passageway that is always open and a front passageway that is adjustable so that the operator can adjust the amount of flow through ventilation to control the humidity in the pan. The lid for the pan also functions as a refrigerator shelf and the back passageway is defined by a gap between the lid and the back of the pan. The front passageway is defined by a front lid plenum having a floor with a plurality of ports. A slide gate positioned in the plenum has a plurality of windows which, by sliding laterally in the plenum, can be made to respectively align with the ports to enable flow through ventilation. Full or partial sealing of the ports is provided by sliding the slide gate laterally to alter the alignment of the windows with the ports.
