赤外線発生装置３１の課題とされるものとなっていた。However, in the conventional far-infrared ray generator 31 described above, firstly, the above-mentioned far-infrared ray emitting material is very expensive, and therefore a means of forming the film 34, such as spray painting, is thick and has low adhesion efficiency. However, the far infrared ray generator 31 becomes very expensive and its range of use is limited.Secondly, the coating 34 is relatively thick (-30 mL for boat fishing). ~40 μm), therefore, there is a problem that the surface of the glass tube 33 peels due to the difference in expansion coefficient due to temperature changes during use. This was considered to be an issue.

効果も確認された。[Embodiment] Next, the present invention will be explained in detail based on an embodiment shown in the drawings. What is indicated by the symbol 1 in Figure 1 is a far-infrared generator,
This far-infrared ray generator 1 includes an incandescent light bulb 2 in which a bulb 2a is formed of a soft glass such as lead glass or soda-lime glass, which is very commonly used as a member for this purpose, and a surface of the bulb 2a with, for example, Z. rO2 and a coating 3 formed of a far-infrared emitting substance, and in particular, the coating 3 has a thickness of 0.05 to 0.5μ according to the present invention.
The film thickness is said to be m. Here, the coating 3, which is the gist of the present invention, has a thickness of 0.05
To explain in more detail the effect of setting the thickness to 0.5 μm, the thermal expansion coefficient of the soft glass on which the bulb 2a is formed is approximately 100×10/deg, whereas the far infrared rays The thermal expansion coefficient of a radiation material such as ZrO2, that is, the thermal expansion coefficient of the coating 3 is approximately 8 x 10-
It is 7/deg. Therefore, when the coating 3 is formed in close contact with the surface of the bulb 2a, the peeling phenomenon is likely to occur between the two due to heat generation caused by lighting of the incandescent light bulb 2, etc. As a result of the study (note), it was confirmed that it is possible to prevent the above-mentioned peeling by reducing the thickness of the coating 3 to 0.5 μm or less. The valve 2 that often occurs when the coating 3 is coated on the surface of the valve 2a.
It was confirmed that cracks on the a side can also be prevented. At the same time, in the above trial production study, it was found that setting the film thickness of the coating 3 to 0.05 μm or less is extremely infrared rays (wavelength 4
It was confirmed that the film thickness of the coating 3 as the far-infrared ray generating device 1 was determined by confirming that the above numerical value range was appropriate. From the above results, the far infrared ray generator 1 of the present invention is 1/4 as compared to an extremely ordinary incandescent light bulb 2 and a conventional one.
A dramatic cost reduction is possible with a film thickness of 0 to 1/800, that is, a usage amount of the far infrared emitting material. What is shown in FIG. 2 is a method of manufacturing the far-infrared ray generator 1, in which an incandescent lamp 2 with a bulb 2a formed of soft glass, which is very commonly used as a member for this purpose, is replaced with a zirconium lamp. Alkoxide 10% solution 10
The solution 10 is applied to the surface of the bulb 2a by a dip coating method in which the bulb 2 is immersed in the solution and pulled out at a rate of 2 w/sec, and then baked at 400° C. for about 10 minutes. By doing this, zirconium is precipitated in the 10% zirconium alkoxide solution 10, which is further oxidized to become zirconia (zirconium oxide-ZrO2), which is a far-infrared emitting material, and is produced as the coating 3 having a predetermined thickness. By using the dip coating method described above, the adhesion efficiency is increased and the usage rate of the solution 10 is improved. In addition, the above-mentioned 10% zirconium alkoxide solution 1
0 can be easily obtained by dissolving zirconium alkoxide in a predetermined amount of alcohol. Further, according to the inventor's test results, the zirconia (z 1-02 ) coating 3 obtained through the above process is obtained as an amorphous transparent film, and as a result, the far-infrared ray generating device 1 is It has been confirmed that the incandescent light bulb 2 does not impair its illumination effect, and it has also been confirmed that, for example, when used for the purpose of preserving the freshness of food in a refrigerator, it is possible to simultaneously illuminate the inside of the refrigerator. It was done.

By providing a far-infrared ray generator and its manufacturing method, we have succeeded in producing inexpensive incandescent light bulbs, which are commonly supplied in large quantities in the market, and far-infrared rays, which are used in an extremely small amount compared to conventional methods. It has the excellent effect of making it possible to manufacture far-infrared ray generators with radioactive materials, dramatically reducing costs, and widening the range of applications for which this type of far-infrared ray generator can be used. The thickness of the coating of the far-infrared emitting material is 0905 to 0.5 μm.
In this range, there is no peeling of the coating or cracking of the bulb, and the durability of this type of far-infrared generator is significantly improved. Furthermore, the coating produced by the manufacturing method becomes an amorphous transparent coating, which also has the effect of allowing far-infrared radiation and illumination to be performed simultaneously without impairing the original illumination effect of the incandescent light bulb. becomes.
