題はこの格子にもあてはまる。 Radiant heaters are used in various forms for heating, drying, melting, etc. The reflector is provided to concentrate the radiant heat from the heater on the target object. If reflectors are used in air, they will become dirty and corrode. Therefore, it has been proposed to apply a reflective metal layer to the outer surface of the heater bulb. However, if this is done, the shape of the reflector cannot be selected independently of the shape of the tube, and there are disadvantages in that the reflective metal and the substance constituting the tube are likely to cause a chemical reaction. It is also difficult to arrange the reflector together with the heating coil inside the bulb. This is because chemical reactions occur, especially in tubes filled with halogen. Also, inside the bulb, there is a metal grid surrounding the heating coil so that the conductive metal part can be touched even if the bulb breaks, but the problem with the reflector mentioned above is due to this grid. This also applies.

である。OBJECTS OF THE INVENTION It is an object of the present invention to construct a radiant electric heater in such a way that the coil temperature can reach approximately 3000°C without suffering any structural damage, and to further provide a metal reflector or shielding grid. It is an object of the present invention to provide a radiation type electric heater in which the metal portion is provided close to a heating coil and chemical wear due to corrosion etc. does not occur.

The first bulb is made of quartz glass and filled with halogen or lamp gas, and the end of the first bulb is tightly crushed and sealed using molybdenum foil while the coil is inserted through the tube. The second bulb is configured to be filled with an inert gas.

からの放熱を非常に小さくすると有利である。 According to the present invention, the heating coil temperature can reach up to about 3000°C, and the atmosphere in the heater can be raised up to 1200°C without suffering structural damage.
Furthermore, corrosion of the metal parts of the reflector and/or the shielding grid is reliably prevented. It is also advantageous to have very low heat dissipation from the tube by convection.

The first bulb 2 is evacuated to air and then filled with materials commonly used in such radiant heaters, such as lamp fill gas, halogen, etc. This first bulb 2 is enclosed in a second bulb 4 together with a reflector 6 and/or a shielding grid 7, or is compressively sealed by heat-sealing foil pieces 5,8. The second bulb 4 is evacuated or filled with inert gas and then sealed. The reflector 6 may be brought into abutment against the inner wall of the bulb 4 under the action of a spring bias force. In contrast, the shielding grid 7 is always connected to protective earth.
The cross-sectional shape of the reflector 6 is a part of a circle, a parabola, or a part of an ellipse. In this case, the first tube 2 does not need to be arranged coaxially with the second tube 4.
