産業上の利用分野
本発明は、電気エネルギーを利用する面状発熱体に関す

熱源、特に輻射加熱源を提供するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sheet heating element that utilizes electrical energy, and is suitable for use as a heat source for heat utilization equipment such as space heaters, cookers, and dryers, particularly as a radiant heating source. This is what we provide.

従来の技術
従来の技術の多くは、マイカなどの絶縁基板に電熱線を
巻回した構造のものが用いられている。BACKGROUND OF THE INVENTION Most conventional technologies use a structure in which a heating wire is wound around an insulating substrate such as mica.
また最近では、アルミナ等の陶磁器質焼成ブロック中に
、導電回路を所望形状に埋設した面状発熱体もある。Recently, there are also planar heating elements in which a conductive circuit is embedded in a desired shape in a ceramic fired block such as alumina.

縁フィルムを接若したものが広く採用されている。In addition, this type of sheet heating element includes polyester I on one or both sides of a sheet metal heating element made of aluminum, copper, nickel, stainless steel, iron, etc., which is formed into a desired circuit shape such as a serpentine or spiral shape. Films with synthetic resin insulating films attached, such as fibers, polyimide films, and polycarbonate films, are widely used.
発明が解決しようとする問題点
しかしながら、従来の技術では、以下のような問題点が
あった。Problems to be Solved by the Invention However, the conventional technology has the following problems.
マイカヒータの場合は、電熱線を基板に巻回するのに手
間がかかる上に、マイカと電熱線との接触が悪くなると
電熱線が空焼きとなり高温になり断線し易いこと。また
、電熱線が封口されていないため、耐熱性に問題があっ
た。またマイカ自体の熱伝導率が低いため、ヒータ温度
が高温となり、劣化し易いという問題があった。In the case of mica heaters, it takes time and effort to wind the heating wire around the board, and if the contact between the mica and the heating wire deteriorates, the heating wire becomes dry and becomes hot, making it easy to break. Furthermore, since the heating wire was not sealed, there was a problem with heat resistance. Furthermore, since the thermal conductivity of mica itself is low, the heater temperature becomes high and there is a problem that it is easily deteriorated.
また陶磁器を用いるヒータの場合には、陶磁器焼成ブロ
ックの機械的強度が低いため厚みが厚くなって熱容量が
大きくなるため、速熱性が悪く、また焼結温度が高いた
め、接点材料の酸化・溶融などにより、電極の取出しに
問題があった。In addition, in the case of a heater using ceramics, the mechanical strength of the ceramic firing block is low, so the thickness increases and the heat capacity increases, resulting in poor heating speed and high sintering temperature, which causes oxidation and melting of the contact material. There were problems with taking out the electrodes.

ましいが、逆に1耐熱性の而では、耐熱性が低下する方
向となり、両者のバランスを考慮すると300°C以上
の高温での使用は困難であった。Furthermore, in the case of enamel heaters, the manufacturing method is extremely complicated and time-consuming, and from the viewpoint of the electrical insulation properties of the enamel layer, it is difficult to make the enamel layer dense, with less alkali content such as Na, and borosilicate. It is desirable to increase the thickness of the abrasion layer, but on the other hand, if the heat resistance is 1, the heat resistance tends to decrease, and when considering the balance between the two, it is difficult to use it at high temperatures of 300°C or higher. .
また、シリコン樹脂、ポリイミド樹脂などのフィルムを
用いるヒータの場合には、その使用温度が絶縁フィルム
の耐熱温度に左右されてしまうところから、例えば25
0°C以上に発熱させた場合は絶縁フィルムに損傷をき
たす欠点があった。In addition, in the case of heaters using films made of silicone resin, polyimide resin, etc., the operating temperature depends on the heat resistance temperature of the insulating film, so for example 25
If the heat is generated above 0°C, the insulating film may be damaged.
本発明は、かかる従来の問題点を解消するもので金属発
熱体素子を二枚のシート間で加熱圧着することで、40

薄型かつコンパクトな面状発熱体を提供することを目的
としている。The present invention solves these conventional problems by heat-pressing a metal heating element between two sheets.
Can be used sufficiently at surface temperatures of 0 to 500°C,
The purpose is to provide a thin and compact planar heating element.
また、生産性に優れ、焼成時にも比較的、煙の発生が少
なく安価に製造できる面状発熱体を提供することも本発
明の目的である。Another object of the present invention is to provide a planar heating element that has excellent productivity, generates relatively little smoke during firing, and can be manufactured at low cost.

囲のものを用いるのが望ましい。かさ密度が0.2より
小さくなると加熱EE着が困難となり、05を越えると
含浸性が悪くなるためである。It is desirable to use a bulk density of these base materials in the range of 0.2 to o, sy/-. This is because if the bulk density is less than 0.2, heating EE adhesion will be difficult, and if it exceeds 0.5, the impregnating property will be poor.

The temperature is preferably 00 to 300°C, because if polytitanocarbosilane is insufficiently heated or dried excessively, its self-adhesiveness and adhesion to the substrate will deteriorate.

シランを用いたシートは、焼成時において発生する煙が
少なく、作業環境上有利である。Further, compared to the case where a borosiloxane polymer is used as the sheet sandwiching the metal heating element, a sheet using polytitanocarbosilane generates less smoke during firing, which is advantageous in terms of the working environment.
また、工法が簡単であり、生産性に優れている点も特徴
である。It is also characterized by its simple construction method and excellent productivity.
更に、赤外線高輻射体を配置すれば、赤外線輻射加熱体
として有効な面状熱源となる。Furthermore, if an infrared high radiant body is arranged, it becomes an effective planar heat source as an infrared radiant heating body.
