ていた。Problems to be Solved by the Invention However, in the above conventional configuration, the radiant energy emitted by the high-temperature heater wire is blocked by the ceramic surrounding the heater wire, and after being absorbed by the ceramic, the radiant energy is transferred to the lower temperature. Since it is converted into far-infrared rays, the total radiant energy is not effectively transmitted to the person taking the heat, and the problem is that it is visually dark and gives a poor feeling of heating.

外線が、石英ガラスを透過して前方へ強く放射される。With this configuration, when the heater wire is energized, the radiant energy from the heater wire is reflected directly or by the specular reflector provided on approximately half of the back, and the near infrared rays accompanied by visible light are emitted from the quartz. It passes through the glass and is emitted strongly forward.

実施例
以下本発明の一実施例について、第１図〜第３図を参照

7 and guard 18 are the same as those in the conventional example.

は効率よく前方へ反射される。In the above construction acid, when the heater wire 16 is first energized,
The heater wire 16 reaches a temperature of 8oOP-1ooooC and emits strong radiant energy accompanied by visible light, and the energy on the short wavelength side, including this self-reflection light, is transmitted through the front part of the tube 13 and reflected from the back of the tube 13. It is reflected by the body 14 and radiates forward. In addition, the energy on the long wavelength side is stored inside the tube 13, increases the temperature of the tube 13, and is transferred to the tube 13 by heat conduction.
The temperature of the far-infrared radiator 16 coated on approximately half of the back surface of the infrared radiator 16 increases, and radiates energy on the longer wavelength side of infrared rays toward the reflector plate 17. Here, the reflection plate 17 is generally made of aluminum with a mirror finish, and its reflection efficiency is 3
As shown in the figure, the long wavelength side has a high reflection efficiency, so the long wavelength side energy radiated from the far-infrared radiator is efficiently reflected forward.

優れた電気ストーブを実現できるものである。Effects of the Invention In the present invention, a specular reflector is formed as a thin film on approximately half of the back surface of the tubular heater, and a far-infrared radiator is coated on the thin film, so that infrared energy on the short wavelength side, including visible light, is absorbed by the specular reflector. In addition, infrared energy on the long wavelength side is radiated toward the reflector by the far-infrared radiator, and can be reflected forward with high efficiency by the aluminum reflector. Accordingly, it is possible to realize an excellent electric stove that has a visual heating effect that enables long-wavelength infrared radiation with high absorption efficiency by the irradiated object without reducing the amount of radiant energy transmitted.
