An electric heating unit for detachable mounting in a motor vehicle includes an outer casing adapted to be fixedly secured in the vehicle and having a recessed portion for removably receiving an electrical heating appliance, such as a water heating pot, provided therein with an electric heating element and a temperature sensor capable of producing switching signals indicative of the temperature of the appliance. A power control switch and switch actuator responsive to the temperature sensor are located in the outer casing at a location remote and shielded from the heating element when the appliance is seated in the recessed portion. The power switch is connected in series with the heating element in a power supply circuit by mating detachable connectors on the outer casing and heating appliance. The temperature sensor and switch actuator are connected in series through the detachable mating connectors in a control circuit in parallel with the power supply circuit. The outer casing only partially encloses the appliance thereby permitting use thereof while seated in the casing.

DETAILED DESCRIPTION An object of the present invention is to provide a heating appliance for installation in a vehicle, in which a heating pot is safely fixed on the vehicle body in a such a manner that it is detachable from the vehicle body when desired.
A further object of the invention is to provide a small heating appliance for installation in a vehicle, in which a heating pot is safely fixed on the vehicle body in such a manner that it is detachable from the vehicle body when desired.
Another object of the invention is to provide a heating appliance for installation in a vehicle, in which a heating pot is safely fixed on the vehicle body in such a manner that it is detachable from the vehicle body when desired with an outer casing thereof being equipped with a switch for easy control of power supply to the heater.
The subject matter of the present invention provides a heating device with an outer casing which does not cover the entire surface of a housed heating appliance so that the heating appliance can be used even when the appliance is stored in the outer casing and the temperature of the heating appliance is detected by a temperature sensor provided within the heating appliance.
The supply of electric power to the heating appliance is controlled by a relay provided within the outer casing and responsive to a control signal from the temperature sensor in the heating appliance.
The electrical components provided within the outer casing are located in a position remote and shielded from the electric heater of the electric heating appliance when the appliance is stored in the outer casing.
