More Information
Summary:A heating device of the present invention includes a main power source and an auxiliary power source implemented by a chargeable capacitor. A heater is made up of a main heating element that heats when supplied with power from the main power source and an auxiliary heating element that heat when supplied with power from the auxiliary power source. A charger charges the capacitor of the auxiliary power source when supplied with power from the main power source. A switch selectively causes the auxiliary power source to be charged or to feed power to the auxiliary heating element. A controller adjusts the power to be fed from the auxiliary power source to the auxiliary heating element.
