Description
【発明の詳細な説明】 産業上の利用分野 本発明は、電気ストーブに関するものである。Description: FIELD OF THE INVENTION The present invention relates to electric stoves.
従来の技術 ランプ式発熱体は、円筒状の石英管内にコイル状に巻い
たタングステン線を挿入し、アルゴン等の不活性ガスを
注入し、石英管の両端を封口した構造である。2. Description of the Related Art A lamp-type heating element has a structure in which a tungsten wire wound in a coil shape is inserted into a cylindrical quartz tube, an inert gas such as argon is injected, and both ends of the quartz tube are sealed.
タングステン線は、空気中で通電すると昇華してしまう
ため、封口部で、モリブデン箔を中継して、モリブデン
線と接続され、モリブデン線により、リード部が形成さ
れている。Since the tungsten wire is sublimated when energized in the air, it is connected to the molybdenum wire by relaying the molybdenum foil at the sealing part, and the lead part is formed by the molybdenum wire.
モリブデンとタングステンは溶着しにくく、封口部の石
英管の溶着のみで互いに接続されているため、封口部が
高温（約２５０℃以上）になると接続部が外れやすくな
る。Since molybdenum and tungsten are difficult to weld and are connected to each other only by welding the quartz tube in the sealing portion, the connection portion is likely to come off when the sealing portion reaches a high temperature (about 250 ° C. or higher).
従来のランプ式発熱体の固定は第５図のような構造にな
っていた。The conventional lamp type heating element is fixed as shown in FIG.
すなわち、ランプ式発熱体１は、支持台３に金具４で固
定されており、封口部２を金具４との固定部としている
ため、封口部２は本体設置方向と平行となる。That is, the lamp-type heating element 1 is fixed to the support base 3 by the metal fitting 4, and the sealing portion 2 is fixed to the metal fitting 4, so that the sealing portion 2 is parallel to the main body installation direction.
発明が解決しようとする問題点 しかし、このような構造のものでは、封口部２は対流熱
の上昇方向に巾広面があるため対流熱が封口部２にたま
り、温度が上昇しやすく、接続部の信頼性があまりなか
った。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a structure, since the sealing portion 2 has a wide surface in the rising direction of the convection heat, the convection heat is accumulated in the sealing portion 2 and the temperature easily rises. Was not very reliable.
そこで、本発明は接続部の信頼性を向上するため、封口
部の温度低下が行えるようにするものである。In view of this, the present invention improves the reliability of the connecting portion, so that the temperature of the sealing portion can be lowered.
問題点を解決するための手段 そして、上記問題点を解決する本発明の技術的な手段
は、前記ランプ式発熱体の封口部を反射板の外方に出し
て、この封口部の巾広面を本体設置面とは垂直方向に向
けるとともに、この封口部内方のランプ式発熱体の管部
を、前記反射板に固定したものである。Means for Solving the ProblemsThe technical means of the present invention for solving the above problems, the sealing portion of the lamp-type heating element is exposed to the outside of the reflection plate, the wide surface of the sealing portion. It is oriented in a direction perpendicular to the main body installation surface, and the tube portion of the lamp-type heating element inside the sealing portion is fixed to the reflection plate.
作用 この技術的手段による作用は次のようになる。Action The action of this technical means is as follows.
すなわち、ランプ式発熱体の封口部の巾広面は、垂直方
向に位置しているため、上昇気流は封口部をなめて通過
し、熱交換特性が向上し、放熱が良くなる。That is, since the wide surface of the sealing portion of the lamp-type heating element is positioned in the vertical direction, the rising airflow licks and passes through the sealing portion, improving heat exchange characteristics and improving heat dissipation.
また、ランプ式発熱体の保持を、封口部内方の管部で行
なっているため、封口部は開放状態であり、放熱が良く
なり、封口部の温度上昇を防ぐことができる。Further, since the lamp-type heating element is held by the tube portion inside the sealing portion, the sealing portion is in the open state, the heat dissipation is improved, and the temperature rise of the sealing portion can be prevented.

に、本体設置面とは垂直方向に向けているため、本体内
部の上昇気流は封口部１３の表面をなめて上昇する。Further, as shown in FIGS. 2 and 3, the wide surface of the sealing portion 13 is oriented in a direction perpendicular to the main body installation surface, so that the upward airflow inside the main body licks the surface of the sealing portion 13 and rises. .
またランプ式発熱体８の管部をＵ型金具１７で保持固定
しているため、封口部１３の周囲は開放状態となり放熱
性が良い。Further, since the tube portion of the lamp-type heating element 8 is held and fixed by the U-shaped metal fitting 17, the periphery of the sealing portion 13 is in an open state and the heat dissipation is good.
さらに、ランプ式発熱体８の石英管９よりの伝導熱は、
Ｕ型金具１７に吸収され、側面反射板７の取付面１４に
伝わり、放熱されるため、封口部１３への伝導熱が少な
くなる。Further, the conduction heat from the quartz tube 9 of the lamp type heating element 8 is
The heat is absorbed by the U-shaped metal fitting 17, is transmitted to the mounting surface 14 of the side reflector 7, and is radiated, so that the conduction heat to the sealing portion 13 is reduced.
以上のごとく本実施例では、ランプ式発熱体８の封口部
