いがプラスチツクフイルムは耐熱性が100〜200℃
と低いために250〜300℃の高温度では使用するこ
とはできない欠点があつた。 Conventionally, planar heating elements such as carbon attached to glass fibers are often sandwiched between plastic films such as Teflon films or polyester films, but plastic films have a heat resistance of 100 to 200 degrees Celsius.
Because of its low temperature, it had the disadvantage that it could not be used at high temperatures of 250 to 300°C.
本考案は上記欠点を除くためになされもので、
250〜300℃の高温で使用できるものであり、構造

るものである。 The structure of the embodiment is as shown in the figure, in which numeral 1 is a metal plate, on the surface of which is coated a highly electrically insulating enamel body 2 with a thickness of 100 microns or more.
Reference numeral 3 denotes a planar heating element, which is made by adhering carbon to the surface of a net-shaped glass fiber or by punching or etching metal foil, and is placed on the metal plate 1 on which the enamel body 2 is attached. 4 is an enamel body, which has a softening point lower than or equal to that of the enamel body 2, and the enamel has a softening point of 400°C.
Using the above material, the surface of the sheet heating element 3 is covered and fixed to the enamel body 2 attached to the metal plate 1.

を保護し強度的に強固にするものである。 The operation of this embodiment will be explained. The enamel body 2 adhered to the surface of the metal plate 1 has a softening point of 400
It's over ℃. Planar heating element 3 made of carbon or metal foil
The enamel body 4 is covered and fixed, and the enamel bodies 2 and 4 form a sandwiching structure. Also, since the carbon or metal foil is made into a net, the enamel body 4 can fit into every corner, and the planar heating element 3 made of carbon or metal foil is well fixed. The heat is immediately radiated through the metal plate 1. Further, the metal plate 1 is a planar heating element 3 made of carbon or metal foil.
It protects and strengthens the structure.
