ABSTRACT:
A heating and cooling tray (10) for service of food comprises housing (12) which supports a Peltier temperature controlling unit (22, 24) having an air flow passageway therein. The housing includes upper and base portions (14, 16) having respective openings (60, 62) for receiving and supporting different parts of the temperature controlling unit. The upper and base portions are secured together to provide an air flow path having an entry at the front of the tray where the upper and base portions are joined at an intersection (28a) and an outlet (58) at the rear of the tray between the upper and base portions, for flow of air through the entry at the intersection, the passageway in the temperature controlling unit, and out through the outlet. A pan (85) and a thermally insulating liner (92) are spaced from one another to form a gap (99) filled with a thermally insulating foam (101) and, thus, to provide enhanced thermal insulation. The liner includes a ridge (96) to insulate a heat conducting plate (78) of the temperature controlling unit.
