Abstract: A serving dish having a heater, and a method for assembling the dish. An electric heater including a resistance element enclosed in a heat conducting and electrical insulating material is adhesively bonded against the bottom of a serving dish of ceramic or the like. Holes through the material covering the resistance element provide for electrical contact with the resistance element, and these holes are filled with solder. A bottom plate of stainless steel or other electrically conductive sheet is adhesively bonded over the heater, and the bottom plate is heated to melt the solder and cause the solder to fuse to the bottom plate. The entire bottom plate has its edges sealed by a silicone rubber sealant or the like to encapsulate the heater. The resulting dish has a bottom plate to give a neat appearance, the bottom acting as electrical contacts to energize the heater and heat the contents of the serving dish.

Abstract: An electrically heated oven for mobile vehicles, such as vans or recreational vehicles, includes a tightly closed oven compartment divided by an internal, imperforate, vertical secondary wall spaced from the back wall of the oven into a front cooking chamber and a rear heater chamber. A thermostatically controlled, plate-like, low wattage electric resistance heating element operable at the vehicle voltage is located within the heater chamber intermediate the upper and lower edges of the secondary wall, which edges are spaced from the top and bottom walls of the oven to allow convection air flow between the cooking and heater chambers. The front surface of the secondary wall is dull and roughened to readily dissipate heat into the cooking chamber and the rear surface of the secondary wall is smooth and shiny to minimize absorption of heat thereby from the heating element. The oven is mounted from a face plate for easy installation into the vehicle.
