Open fronted cabinet
The present invention relates to an open fronted food storage cabinet. The cabinet has a top, rear, base and opposed sides. The top, rear, base and opposing sides define an interior space of the cabinet which is accessible through an opening to the front of the cabinet. The opening is defined between edges of the top, base and opposing sides of the cabinet. The cabinet includes an interior chassis structure comprised of a base panel, a rear panel and a top panel which are mechanically connected to one another. The base, rear and top panels are each formed from a structural sandwich composite material having thermal insulation properties. The rear panel includes an aperture to which a mechanism operable to alter the temperature within interior space of the cabinet is mounted.
1. An open fronted food storage cabinet, comprising:
a top, rear, base and opposed sides, the top, rear, base and opposed sides defining an interior space of the cabinet which is accessible through an opening to a front of the cabinet defined between edges of the top, base, and opposing sides of the cabinet, wherein the cabinet includes an interior chassis structure comprised of a base panel, a plurality of rear panels, a top panel and at least one intermediate panel which are mechanically connected to one another, the at least one intermediate panel being positioned between adjacent ones of the plurality of rear panels to divide the interior space into at least two portions, further wherein the base panel, plurality of rear panels, at least one intermediate panel and top panel are each formed from a structural sandwich composite material having thermal insulation properties, and further wherein at least one of the plurality of rear panels includes an aperture; and
a cassette disposed in the aperture, the cassette including a mechanism operable to alter the temperature within the interior space, the cassette being fittable to and removable from the aperture.
