ABSTRACT:
A device for heating an article up to a selected controlled temperature by irradiation of infrared rays upon the article of both longer and shorter wave lengths simultaneously as well as by conventional hot air. The infrared radiation evolves from an electrical generator behind a foraminious or perforate sheet forming a second radiation source of infrared rays of longer wave length than that of the generator through its absorption of the shorter rays from the generator while its perforations allow direct rays from the generator to pass through. The second radiator or perforate sheet is also used to control electrical current to the generator by its expansion and contraction to limit the generator's highest temperature while motivated air flows through the generator and the openings in the perforate sheet and being heated thereby flows on, aiding the radiation to heat the article. In other forms a reflector is used to return unobstructed rays back to the article or a pair of generator radiators are placed in opposed relationship.
