Abstract

Abstract An adjustable air deflector condensate directing tray and food receptacle shelf support cover for a refrigerator cabinet shelf. The cover includes side flanges, spaced to depend between shelf longitudinal openings, with the flanges having opposed trackways for receiving outwardly flared receptacle top flanges. The tray is releasably retained in the opposed trackways allowing same to initially protrude rearwardly of the removed shelf. Upon the cover and tray being assembled with the shelf and the shelf assembly being installed in the cabinet, tray stop members contact the cabinet rear wall to telescope the tray in the trackways thereby compensating for cabinet liner rear wall out of plane undulations providing a baffle for directing refrigerated air into the receptacle while condensate collected thereon is directed to the cabinet liner rear wall.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 292 words
In combination with a refrigerator cabinet having a food storage chamber, a shelf removably mounted in cantilever fashion from the rear wall of the chamber having a plurality of longitudinal extending spaced open areas, a food storage assembly including a drawer and a supporting cover plate member therefor overlying the upper surface of the shelf, said cover plate including integral flange means depending from each side thereof and laterally spaced so as to extend through a pair of the open areas to project from the underside of the shelf, said flange means providing confronting longitudinal extending trackways, means on said drawer in slidable supporting engagement with said trackways, said drawer having a predetermined longitudinal dimension less than said plate member, an air deflector tray in slidable engagement with the rearward portion of said trackways, said tray being vertically spaced from said cover plate to provide an air flow passage therebetween communicating with the interior of the drawer, a plurality of spacer means extending from the rear wall of said tray, releasable means for retaining said tray in said trackways, whereby said tray initially extends rearwardly from the shelf a predetermined dimension such that upon the installation of the shelf on the chamber rear wall certain ones of said tray spacer means engage the chamber rear wall resulting in the disengagement of said releasable means causing telescoping movement of said tray in said trackways to a final position compensating for any undulations in the chamber rear wall, and thereby positioning said tray to direct the required quantity of refrigerated air dispensed to the chamber into the drawer via said air flow passage while said spacer means define a passage to allow condensate on the chamber rear wall to flow downwardly past said tray.
