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. The cooking chamber is illuminated by an electric lamp external of the oven top wall and operable at the vehicle voltage. The oven walls are covered by thick thermal insulation to minimize heat losses.

An oven for mobile vehicles and the like for operation from the vehicle\s electrical system, said oven including a cooking chamber defined by a top and bottom, side walls connecting said top and bottom, and a back closing the rear of said cooking chamber, a face plate carrying said top and bottom and said side walls for mounting said oven within a vehicle, said face plate defining an opening therein for providing access to said cooking chamber, a door hinged to said face plate for selectively closing said opening, catch means for holding said door tightly closed, and sealing means between said door and said face plate to prevent heat loss, a secondary wall generally parallel to and spaced inwardly from said back, said secondary wall extending substantially the width of said cooking chamber and having less height than said cooking chamber, a low wattage electrical heating element operable on the voltage of a vehicle\s electrical system for heating said cooking chamber, said electrical heating element being plate-like and mounted between said back and said secondary wall parallel to said secondary wall, the arrangement being such that air currents can pass beneath said secondary wall to be heated by said heating element and can pass over said secondary wall and into said cooking chamber, said secondary wall having a rear surface facing said heating element and a front surface facing said cooking chamber, said rear surface being smooth and shiny to reflect radiant heat, said front surface being dull and roughened to readily dissipate heat therefrom into the cooking chamber, so that said secondary wall will have a temperature no higher than the temperature of said cooking chamber, and a light operable on a vehicle\s electrical system for selectively illuminating said cooking chamber, said light including a light socket and a bulb, said light socket being mounted on said top, outside said cooking chamber, a heat insulator disposed between said light socket and said top, and a hole defined in said top aligned with said bulb for admitting light into said cooking chamber, a temperature sensing means disposed within said cooking chamber and control means for selectively energizing said heating element in response to said temperature sensing means, and thick thermal insulation covering said walls, said top and bottom and said back of said oven, said light being between said insulation and said top.
