Abstract

(57) [Summary] [PROBLEMS] To obtain a large-sized and efficient planar far-infrared heater in which a radiation plate is not cracked or deformed. SOLUTION: A high-temperature infrared radiation ceramic is directly passed through a heating wire, and the heating wire is braided into a radiation plate on a bone.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a new concept of a flexible far-infrared heater having a planar shape for efficiently heating an object to be heated by radiating far-infrared rays at high density.

[0002]

[Prior art]

 Conventionally, a method of heating a radiator plate with a far-infrared radiating material coated on the surface of a ceramic plate or a metal plate with a heating wire from the back was used, resulting in poor heating efficiency. In this case, it was easy to crack due to thermal distortion or thermal shock, and in the case of a metal plate type, it was impossible to produce a large-sized heater because it was deformed by thermal distortion.

[0003]

[Problems to be solved by the invention]

 An object of the present invention is to provide a large-sized far-infrared heater that improves the conventional heating efficiency and does not deform due to cracking or thermal distortion of a heat sink.

[0004]

[Means for Solving the Problems]

 The means of the present invention are as follows.

[0005] By alternately arranging insulator bodies each having a plurality of through holes for penetrating a heating wire and having ceramics formed and fired with high far-infrared radiation efficiency, the heating wires are passed through the through holes and braided. A large planar infrared heater has been formed.

[0006]

[Embodiment of the invention]

1 and 2 are insulator bodies made of far-infrared radiation ceramics such as far-infrared radiation materials (Al ₂ O ₃ , SiO ₂ , ZrO ₂ , TiO ₂ , SiC, CoO, SI ₃ N _4). 2 are formed at two places.

As shown in FIG. 3, a large number of insulator main bodies 1 are arranged in multiple stages in the direction of the heating wire through-hole 2 and are aligned with the next stage by half.

FIG. 4 shows a state in which the insulator main bodies 1 arranged as described above are braided in a row shape through the heating wires 4 and the respective heating wires 4 are connected. Then, voltage supply terminals 5 are attached to both ends.

[0009]

[Effect of the invention]

 According to the present invention, since heating can be performed directly from the inside of the far-infrared radiator, the radiator has a faster heating time, has less heat loss from the back surface, and emits high-density far-infrared ray energy. Therefore, the heating efficiency is extremely good. Furthermore, since the far-infrared radiator is flexible, there is no risk of cracking or deformation, and large-sized heaters can be easily manufactured and can be used at high temperatures.
