Description of the Related Art Conventionally, an aluminum plate or a chrome-plated steel plate has been used as a material of a reflector of an electric heater, and a reflector and a casing for holding the reflector are generally used. Although there is an integrated type, distortion occurs at high temperatures, so that a structure was used in which divided parts were assembled in order to release this thermal distortion.

を目的とする。However, in a conventional heater, when an aluminum plate is used as a reflector when the heater is heated to a high temperature, the heater may be softened or deformed.
Mu-mekki steel plates are colored by high-temperature oxidation and their effect as a reflector is reduced. In addition, when the reflector is exposed to high temperature, the integrated type causes distortion due to thermal expansion. If the reflector is divided so as to expand and contract in accordance with expansion and contraction in order to avoid this distortion, the structure becomes complicated. There was. Accordingly, the present invention provides a heating apparatus provided with a reflector which does not cause the reflector to be deformed even when the heater is used at a high temperature for a long period of time without causing a decrease in reflectance due to high-temperature oxidation. The purpose is to:

It is not integrated, but has several slits at locations where thermal expansion is large due to temperature difference, and has a shape that absorbs distortion, eliminating the decrease in reflectance due to high-temperature oxidation and the distortion due to heat.

A stainless steel sheet containing 1 to 8% of aluminum was used as the reflector 2, and the reflectors 2 and the casing 1 were processed with slits 4 and 5 using a laser cutter. As shown in FIG. The reflector 1 and the rod-shaped heater 3 are incorporated into the sing 1 so as to be accommodated therein.

で温度差による熱膨張を分散し歪曲を防いだ。The use of a stainless steel sheet containing aluminum as the material of the reflector results in the formation of a denser and more adherent aluminum oxide film from the interior after the formation of chromium oxide on the reflector surface. The durability at temperature was increased, and the structure was simplified by integrating the reflector and the casing, and the slits were processed and provided, thereby dispersing the thermal expansion due to the temperature difference and preventing distortion.
