できる。Next, the operation and function will be described. Since the carbon-based material exhibits excellent heat resistance and corrosion resistance without melting and deforming in a non-oxidizing atmosphere and exhibits electrical conductivity close to that of a metal, the carbon-based material is not provided outside the tube 4. When the power is applied to the extraction wire 9 exposed to the carbon, the carbon-based resistance heating element 5 generates heat and emits radiant energy. Since the carbon-based resistance heating element 5 is straight, even if a plurality of carbon resistance heating elements are located in the tube 4, the outer diameter of the tube 4 does not increase and an electric stove in which the heating element 1 has a compact shape is realized. In addition, since the number of lead wires 9 is equivalent to the number of the plurality of carbon-based resistance heating elements 5, by increasing or decreasing the current supply positions to the lead wires 9, the number of carbon wires in one tube 4 can be increased. It is possible to realize an electric stove in which the number of currents to be supplied to the system resistance heating element 5 can be changed and the output can be changed with one tube 4. In addition, since the carbon-based resistance heating element 5 has a high emissivity, radiant energy from the surface increases, and an electric stove that can increase radiation efficiency can be realized. In the first embodiment, the foils 8 at both ends of the carbon-based resistance heating element 5 are individually formed at both ends. However, as shown in FIG. 4, an electric stove that can perform the same operation even when the foil 6 on one side is integrated is realized. can do. Further, it is possible to realize an electric stove that can electrically connect the take-out wires 9 at both ends of the tube body 4 in either series or parallel. In addition, since the connection wire 7 has a part of spring property, the shock to the carbon-based resistance heating element 5 is weakened even when an external force is applied, so that an electric stove that is strong against vibration and shock can be realized.

Since the second carbon-based resistance heating element 11 has a different length, cross-sectional area, and cross-sectional shape from the carbon-based resistance heating element 5, the second carbon-based resistance heating element 5 and the heating temperature are different. And an electric stove whose output can be changed.
One tube 4 for emitting infrared and radiant energy of a different wavelength from the carbon-based resistance heating element 5
By selectively changing the current-carrying position of the take-out wire 9, an electric stove that can emit infrared rays and radiant energies having different wavelengths with the compact heating element 1 can be realized. In addition, the second carbon-based resistance heating element 11
6 (a), the sectional shape of the carbon-based resistance heating element 5 was changed.
When the cross-sectional shape has the flat portion 12 as shown in (b) and (c), the direction of the infrared radiation is changed by changing the direction of the flat portion 12 between the carbon-based resistance heating element 5 and the second carbon-based resistance heating element 5. The electric stove can be realized in which it is possible to change, or to have or eliminate directivity, with one pipe 4.
