ABSTRACT:
The invention relates to a cabinet in which food packages, such as prepared school lunch packages, can be heated prior to serving, and maintained at a desired temperature before and during serving. The cabinet comprises an upwardly opening well closed by removable lids, a housing connected to and surrounding the well on the sides and bottom thereof and being spaced from the well so as to form a substantially enclosed air circulation chamber adjacent the sides and bottom, and a plurality of louvers in the side walls defining air inlets and outlets between the well and air chamber. Electrical heating elements are mounted within the air chamber directly below the bottom of the well so that heat generated thereby will radiate upwardly thereby heating the well bottom and, to a lesser extent, the well side walls. A thermally conductive baffle plate is disposed within the air chamber beneath the bottom of the well and functions as a heat sink to disperse and even out the radiant heat. An air circulation system comprising a pair of blowers for circulating the air over the heating elements and through the air chamber into the interior of the well through the side wall louvers.
