The heated spiral part (la) acts to prevent direct contact with people or other objects. In addition, in a quartz tube, heating wire (1)
In addition to not requiring insulation between the heater and the sheathed heater, it also has the advantage of emitting more radiation than a sheathed heater and being brighter even at low temperatures.
［発明が解決しようとする課題］
しかしながら上記構成の石英管ヒーターでは、電熱線を
高温で使用すると、らせん状部が倒れ易くなり、また、
らせん状部が直接空気と接触しているので酸化しやすく
寿命の点で問題があった。[Problems to be Solved by the Invention] However, in the quartz tube heater having the above configuration, when the heating wire is used at high temperatures, the spiral portion tends to collapse;
Since the spiral portion is in direct contact with air, it is easily oxidized, which poses a problem in terms of service life.
本発明はこれらの課題を解決するためになされたもので
、高温で使用しても電熱線のらせん状部が倒れることな
く、しかも、長寿命の石英管ヒーターを得ることを目的
とする。The present invention was made to solve these problems, and an object of the present invention is to provide a quartz tube heater that does not cause the spiral portion of the heating wire to collapse even when used at high temperatures and has a long life.
［課題を解決するための手段］
本発明の石英管ヒーターは、らせん状の電熱線を収納し

管の両端を、電熱線の引出線のみを通して、塞いだもの
である。[Means for Solving the Problems] The quartz tube heater of the present invention is provided by filling the space inside the quartz tube housing the spiral heating wire with an electrical insulator, and connecting both ends of the quartz tube to the lead wire of the heating wire. It is something that is blocked through a chisel.
［作用］
本発明によれば、石英管内部の空間を電気絶縁物で充て
んしたので、温度にかかわりなく、らせん状の電熱線が
倒れることはない。また、電熱線は電気絶縁物に覆われ
ているので、酸化しにくくなり、長寿命化が図れる。[Function] According to the present invention, since the space inside the quartz tube is filled with an electrical insulator, the spiral heating wire will not collapse regardless of the temperature. Furthermore, since the heating wire is covered with an electrical insulator, it is less susceptible to oxidation and has a longer service life.
［実施例コ 第１図は本発明の一実施例を示す正面図である。[Example code] FIG. 1 is a front view showing an embodiment of the present invention.

化にも貢献する。In the quartz tube heater configured as described above, when a voltage is applied to the lead wires (lb) at both ends of the heating wire (1), the spiral portion (1a) generates heat. At this time, in addition to the quartz tube (2) having the same effect as shown in the conventional example, the inside of the quartz tube (2) is filled with an electrical insulator (3), so even if the heating wire reaches a high temperature, Even if the spiral part (1a) falls over, the spiral part (1a) will not fall over.
This makes it difficult to oxidize and contributes to longer life.
