The present invention relates to a far infrared heater using a glass tube.

Description of the Related Art Conventionally, as a heating source for cooking devices such as oven toasters and electric ovens and heaters such as electric stoves, a coiled heating wire is placed in the center of a quartz tube or a crystallized glass tube (trade name: Miracron). Commonly used is a quartz heater or a miraculon heater.

Far-infrared heaters that use far-infrared radiation are in the spotlight.

が、石英管以上によく使用されている。As the far infrared heater, a far infrared radiation layer is formed by coating the surface of the above-mentioned quartz tube or crystallized glass tube with a far infrared paint containing a far infrared radiation material, and then performing heat treatment. , By using this and the far-infrared radiation material directly by coating the surface of the quartz tube or the crystallized glass tube by the thermal spraying method,
A far-infrared radiation layer is formed, and it is roughly divided into two types. However, the former one is general in terms of cost, and many are manufactured by this method. Further, in the former case, as the glass tube used, a crystallized glass tube excellent in mechanical strength and corrosion resistance is more often used than a quartz tube.

高くつくものであった。However, in this method, the heat treatment after applying the far-infrared paint is only performed at a relatively low temperature of 200 to 300 ° C., and therefore (1) the coating film has poor adhesion. (2) Inferior coating hardness. (3) There were various problems such as poor corrosion resistance of the coating film. Therefore, it is conceivable to deal with it by performing heat treatment at 200 to 300 ° C. and then at higher temperature, but this is costly.

中央部に、コイル状の電熱線を配設したものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention uses an alkaline glass silicate or a silicate alcoholate as a binder on the surface of an amorphous glass tube, and a long distance such as zirconium oxide or aluminum oxide. It is manufactured by applying a far-infrared coating material containing an infrared-ray emitting material, predrying this, and then heat-treating the amorphous glass tube at a predetermined temperature to crystallize and form a far-infrared emitting layer. A coiled heating wire is arranged in the center of the crystallized glass tube.

Furthermore, since it is sintered and made into ceramic, it exhibits corrosion resistance against corrosive substances such as salt and soy sauce.

安価なものとなる。Such heat treatment was performed after applying the above-mentioned far-infrared paint to the crystallized glass tube and predrying it,
According to the present invention, since the amorphous glass is crystallized at the same time when it is crystallized, the heat treatment step only needs to be performed once. Therefore, it is considerably rationalized as compared with the conventional manufacturing method, and the cost is low.

線ヒータは安価で、かつ塗膜性能に優れたものとなる。For the above reasons, a far-infrared heater having a far-infrared radiation layer formed on the surface of the crystallized glass tube by the above-mentioned method, and a far-infrared heater having a coiled heating wire inserted in the central portion of the crystallized glass tube is inexpensive. In addition, the coating film performance will be excellent.
