Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat generating element, and more particularly to a mounting structure for a heat generating element.

As shown in Fig. 6, the conventional heating element has a heating wire 1 and an electrode 2.
, an anchor 3, and an insulator 4, but since the heating element with this configuration has the heating wire 1 stretched between both electrodes, the heating wire 1 is easily broken due to vibration, etc. In order to prevent the stretched heating wire 1 from sagging, the heating wire 1 is supported at arbitrary points with several anchors 3 as shown in FIG. However, due to various influences during the manufacturing process, as shown in FIG. A short circuit occurs at
There were drawbacks such as the fact that the exothermic wire 1 was easily blown out.

In order to improve the above-mentioned conventional drawbacks, the present invention aims to solve the following problems:
Electrode 2. A heating wire wrapped core material 5 made of an insulating material such as porcelain, and the heating wire 1. The supporting member 6 to which the electrode 29 and the heating wire-wrapped core 5 are attached is fixed to the four parts by clamping or the like in the positional relationship shown in FIG. 1 to form a heating element.

In the configuration of the present invention, the heating wire 1 is processed into a spiral shape as shown in FIG. Insert the core material 7 bent into a shape into the inside of the heating wire 1,
The heating wire 1 and the support member 6 are configured so that they do not come into contact with each other except through contact such as by biting.

Both ends of the heating wire 1 are fixed to the support member 6 at diagonal positions with the heating wire wrapping core material 5 as the boundary, and
The fixed position of the electrode 2 and the support member 6 is a position opposite to the fixed position of the heating wire 1 with the heating wire wrapped core material 5 as a boundary.
Furthermore, the heating wire wrapping core material 5 and the support member 6 are attached by cutting and raising the nails from the supporting member 6 through holes provided in the heating wire wrapping core material 5 as shown in FIG. They are attached so that they can be combined with each other, and the heating wire-wrapped core material 5 and the support member 6 are in contact with each other only at the surface A in FIG.

As explained above, according to the present invention, the heating wire-wrapped core material around which the heating wire is wound is supported on the supporting member in a freely interlocking manner, and the supporting member is fixed to the two electrodes, so that the electrodes are Even if vibration occurs, the force will not be transmitted to the core material wrapped around the heating wire, and as a result, there will be no risk of deformation or cracking of the core material wrapped around the heating wire, or of the heating wire being disconnected.
