本発明は電熱器具の発熱体のうち高温度で用いるシース
ヒータに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheath heater used at high temperatures among heating elements of electric heating appliances.
従来この種の／−ズヒータは通常金属パイプの両端を低
融点ガラスからなるシールで封止し、内部のセラミック
スよりなる充てん拐料の高温多湿時の８≠４４＝ｅ絶縁
特性の低下を防止していた。Conventionally, this type of heater usually has both ends of a metal pipe sealed with seals made of low-melting glass to prevent the insulation properties of the internal ceramic filler from deteriorating at high temperatures and high humidity (8≠44=e). was.
しかし同ガラスは封止特高温度に加熱するため。However, this glass is heated to extremely high temperatures for sealing.
それが常温になった時点でシーズヒータ内部が負圧とな
夛ヒータのクローム等の金属成分が蒸発し充てん材料に
付着し、シーズヒータの高温時絶縁特性の低下が発生す
るという欠点がある。When the temperature reaches room temperature, there is a negative pressure inside the sheathed heater, and metal components such as chromium in the sheathed heater evaporate and adhere to the filling material, resulting in a decrease in the insulation properties of the sheathed heater at high temperatures.
本発明は上記に関しなされたもので、その目的は高温時

ア粉末に均一にクロムマグネシャ２ａ、＋〜５ ％ ｗ
ｔ混合して構成したものである。The present invention has been made in connection with the above, and its object is to obtain a heater whose insulation properties do not deteriorate at high temperatures. In order to achieve that purpose, filler powder f-rfnesia powder is uniformly filled with chromium magnesia 2a, +~5%w.
It is constructed by mixing t.
以下本発明の一実施例を図面を参照して説明する。１は

る。充てん材料４の充てん。An embodiment of the present invention will be described below with reference to the drawings. 1 is metal pipe, 2 is terminal, 6 is heater wire, 4 is 45
~325 mesh of Magnenoa powder 7 and evenly spread about 150
The filling material is a mixture of meso/yu chromium magnesia 6 from 0.1 to 5% wt, and 5 is a seal made of low melting point glass. Filling with filling material 4.
シール５の封止は従来と同様の作業でよい。The seal 5 may be sealed in the same manner as in the past.

ロムマグネシア６が入っているためその内部はクロム濃
度が高く、ヒータ＃ｉｉ乙の温度が高くなってもヒータ
線３内のクロムが蒸発し難く絶縁特性が低下することは
ない。The operation of the above configuration will be explained. Since the optical fiber material 4 contains chromium magnesia 6, the chromium concentration inside is high, and even if the temperature of heater #ii B becomes high, the chromium in the heater wire 3 is difficult to evaporate, resulting in a decrease in insulation properties. Never.
尚１両マグネシア６．７を均一に混合するためクロムマ
グネシア６を約１５０７ソノユの微粒子としているので
混合状態は良好である（第２図）。その量は０１％ｗ１
以下では効果なく、５％ｗ１以上では金属パイプ１への
充てん率が悪くなる。Furthermore, in order to uniformly mix both magnesia 6.7 and chromium magnesia 6, fine particles of about 1507 soybean were used, so the mixing condition was good (Fig. 2). The amount is 01%w1
If it is less than 5% w1, it will not be effective, and if it is more than 5% w1, the filling rate into the metal pipe 1 will be poor.
以上の如く本発明によれば高温時に絶縁特性が低下しな
いシーズヒータを得ることができる効果がある。As described above, according to the present invention, it is possible to obtain a sheathed heater whose insulation properties do not deteriorate at high temperatures.
