HOUSEHOLD DISH-HEATING APPLIANCE
First Claim
1. A food heating appliance comprising a base having a plurality of recesses and partitions separating said recesses from each other, each of said recesses fitting the shape of a dish to be heated, said base being made of a body of refractory material containing a base heating electrical wire resistance, said base being bounded by two metal plates, a lid closely fitting over said base and partitions and made of a body of heat-insulating material containing a lid heating electrical wire resistance and bounded by an upper and a lower metal plate, said lower plate being polished and reflective, said base and lid containing electrical connecting means for connecting said base heating wire resistance and lid heating wire resistance in series with each other, and said base heating resistance having a resistance value between two and four times that of said lid heating resistance.

Abstract
A food heating appliance comprising a base in bowl form and a lid fitting the shape of one or several dishes to be heated. The base consists of a body of refractory material in which a first heating electrical resistance is embedded; this body is bounded by two metal plates; the lid, fitting over the base and dish or dishes, is also made of a body of refractory material in which a second heating electrical resistance is embedded and is bounded by an upper and a lower metal plate. The lower plate is polished and reflective. The resistances are preferably series-connected.
