ABSTRACT:
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.
