可能性がある。2. Description of the Related Art In recent years, the heat of combustion of electric power and gas has been converted into light having a long wavelength of about 4 to 7 microns, called far-infrared ray, which is easily absorbed by organic substances such as the human body or water, and the human body is irradiated and heated. Electric far infrared radiation sauna or gas far infrared radiation sauna has begun to spread. Far infrared rays having the above-mentioned wavelength are characterized in that they are hardly absorbed by diatomic gas such as air, and are easily absorbed by organic substances such as a human body and water. By utilizing such features, the far-infrared sauna, which emits far-infrared rays directly to the human body without increasing the temperature of the air, has a lower air temperature than the conventional electric convection sauna. Heats the human body efficiently due to the effect of far-infrared radiation, so it may spread widely in the future because it sweats quickly, has no stuffiness and is energy-saving. , Heating devices and the like. That is, far infrared rays
Because it has the characteristic that "it is hardly absorbed by air and easily absorbed by organic matter such as the human body", it is possible to directly absorb far-infrared rays and warm the irradiated object without raising the temperature of the air. Therefore, it will be an energy-saving heating method, and it may be more widely used in the future as well as for the sauna.

Determined by the surface temperature of the object that emits light, the temperature that emits the largest amount of light of about 4 microns, in other words, the surface temperature of the object that generates light with a peak wavelength of about 4 microns, is about 450 ° C. The surface temperature of an object that generates light having a wavelength of about 7 microns is about 150 ° C. For a sauna, light having a wavelength of about 5 to 6 microns is easily absorbed by water or organic matter. Therefore, the surface temperature of the far-infrared radiator has a peak wavelength of the light of about 5 to 6 microns. , That is, about 200 to 300 ° C.

Further, at the same temperature, the ratio between the irradiance and the absorptivity is constant regardless of the substance, and is equal to the irradiance of the black body. Therefore, a material having a high irradiance, that is, a black material having a high absorptivity is applied or adhered to the far-infrared radiation surface of the conventional far-infrared radiation electric heater or far-infrared radiation gas heater. Book
In the specification, the absorption capacity is the light absorption in the far infrared region.
Mean absorption. The absorption capacity is greatest in black bodies
The value is 1. Also, the amount of energy that comes out of an object is
It is proportional to the product of the fourth power of the absolute temperature of the surface of the object, the emissivity of the surface, and the surface area.

当然発生するエネルギーは減少する。[0005] Nichrome wires, sheathed heaters, and the like have conventionally been used in many electric heating appliances that generate light or heat using electric power. However, conventional electric appliances are small and generate more heat.
In most cases, the temperature is higher than 00 ° C. As described above, it is easy to use a heating device having a surface temperature of 800 ° C. or more and reduce the voltage to reduce the surface temperature to 200 to 300 ° C. to obtain a far-infrared radiation electric heater. However, lowering the surface temperature of the electric heating appliance naturally reduces the energy generated.

大きすぎるという問題点がある。That is, as described above, since the amount of generated energy is proportional to the fourth power of the absolute temperature of the object surface, when the surface temperature is reduced from 800 ° C. to 200 ° C., (800 + 273) 4
/ (200 + 273) 4 = 26.5, that is, the amount of energy generated
It will be reduced to 1 / 26.5. Lowering the temperature to 300 ° C. from 1000 ℃ (1000 +273) 4 / (300 + 273) 4 = 24.4, i.e., the amount of generated energy is to be reduced to 1 / 24.4. Even when lowering the temperature from 800 ° C to 300 ° C (800 + 27
3) 4 / (300 + 273) 4 = 12.3, ie the amount of energy generated
It will be reduced to 1 / 12.3. In other words, when a conventional electric heating device is used as a far-infrared radiation electric heating heater, 12 to 27 times the number is required to generate the same amount of heat. This is problematic in that the price is high and the number of instruments is large or the size is too large.

とする必要がある。[Function] Far-infrared rays are light that is easily absorbed by organic substances and water and hardly absorbed by the air. I do. Therefore, when used for heating, etc., the human body can be heated without raising the temperature of the air,
It is widely known that this is a heating method with good thermal efficiency and energy saving. Far-infrared rays have longer wavelengths than visible or near-infrared rays and are emitted from relatively low-temperature objects.The wavelength of light is determined by the surface temperature of the object that emits light, as described above. 5 which is easily absorbed by organic matter
In order to emit far-infrared rays having a peak wavelength of about 6 microns, the surface temperature of the radiator needs to be about 200 to 300 ° C.

You need to use appliances or very large electric appliances,
Practical application was difficult. The present invention can provide a far-infrared radiant electric heater capable of efficiently converting the same amount of heat into far-infrared rays and emitting the same by simply adding simple equipment to a conventional electric heating apparatus by configuring as described above. It is.

ため効率よく大量の遠赤外線が得られるものである。That is, according to the present invention, the radiant energy from an electric heater having a small surface area and a high surface temperature is temporarily absorbed by a metal tube having a large surface area, and is re-emitted as secondary radiation from the outer surface of the metal tube. It lowers the surface temperature of the source of the radiation and converts the radiant energy into long-wavelength far-infrared rays. In other words, even if the metal tube absorbs short-wavelength radiation supplied from the inside, the metal tube has a large surface area, so even if the radiant energy per unit surface area decreases, thermal equilibrium is maintained, and the surface of the metal tube is not so hot. Instead, a large amount of far-infrared rays can be efficiently obtained.

ものである。以上が本発明の第１実施例である。As shown in FIG. 1, the sheath heater 3 is provided eccentrically downward from the center of the far-infrared radiation tube 4 in FIG. 1, that is, in the far-infrared radiation direction. This is because the intensity of light is inversely proportional to the square of the distance.
The reason for this is to heat the radiation portion of Step 4 more strongly and to further increase the amount of far-infrared radiation in the radiation direction. Further, the inner wall on the back side of the far-infrared radiation tube 4 far from the sheath heater 3 is heated not only by near-infrared rays emitted from the sheath heater 4 but also by convection of high-temperature air. Although the rear side of the tube 4 is slightly lower in temperature than the front side, it can function sufficiently as a heat transfer surface for far-infrared radiation. The above is the first embodiment of the present invention.

On the back side of the far-infrared radiation tubes 4 and 4, a reflector plate 5 made of stainless steel or aluminum is provided fixed to the power supply connection box 1, so that light emitted from the far-infrared radiation tubes 4 and 4 is not radiated. When the light is radiated in the direction (on the rear side of the far-infrared radiation tubes 4 and 4 and in the installation direction of the reflecting plate 5), the reflecting plate 5 reflects the far-infrared ray and emits the far-infrared ray toward the irradiation target.

も多量に含む遠赤外線が放射される。In both the first and second embodiments, the reflecting plate 5 is used to reflect far-infrared rays emitted from the far-infrared ray radiating tube 4 to the rear side in the radiation direction. As described, a far-infrared radiation plate may be used instead of the reflection plate 5. The far-infrared radiation plate in this case is a reflection plate 5
A metal plate having the same shape as above is coated with a black paint having the same high absorptivity as the paint applied on the outer surface of the far-infrared ray radiating tube 4, and behind the far-infrared ray radiating tube 4 in the same manner as the reflector 5. It is provided. When such a far-infrared radiation plate is provided, the far-infrared radiation radiated to the back side of the far-infrared radiation tube 4 is absorbed by the far-infrared radiation plate, and when the temperature of the far-infrared radiation plate rises, the far-infrared radiation plate Radiates far-infrared rays in the far-infrared radiation direction. At this time, the far-infrared wavelength emitted from the far-infrared radiation plate is
Since the temperature is lower than the light emitted from the far-infrared radiation tube 4, the wavelength becomes longer, and the temperature of the far-infrared radiation plate becomes 100 to 20.
At about 0 ° C., far infrared rays containing the largest amount of light having a wavelength of about 6 to 8 microns are emitted.

きである。To summarize the above functions, the far-infrared radiation plate converts light radiated from the back side of the far-infrared radiation tube 4 into light having a longer wavelength and radiates it toward the object to be heated. . When the object to be heated absorbs light of a longer wavelength better, the far-infrared radiating plate may exert more excellent effects than the reflecting plate 5. However, when the temperature of the far-infrared radiation plate rises, heat radiation to the back side of the far-infrared radiation plate increases, and in some cases, the heat insulation on the back side of the far-infrared radiation plate must be taken into consideration. When the temperature of the radiating plate rises, air is heated by convection and heat transfer by the far-infrared radiating plate, and the amount of generation of far-infrared rays is reduced accordingly. It cannot be said that the infrared radiation plate is functionally superior, and which one should be adopted should be selected according to the use conditions such as the shape of the apparatus and the characteristics of the object to be heated, and the purpose of use.

熱ヒータを得ることができた。As described at the beginning, if far-infrared rays are to be generated using widely available electric heating equipment, the temperature of the heat-generating surface must be lowered. However, according to the present invention, the temperature of the heat generating surface of the conventional electric heating device is not lowered, and the heat generated from the conventional electric heating device is reduced. By heating the inner surface of the far-infrared radiation tube consisting of a metal tube, it has a heat-generating surface that is sufficiently larger than the heat-generating surface of the electric heater, so that far-infrared rays are generated from the thin-walled outer surface of the metal tube, which is lower in temperature. By using simple means, a simple and inexpensive far-infrared radiation heater can be obtained.

ータが得られるという特徴がある。In the thin metal tube used as the far-infrared ray radiating tube in the apparatus of the present invention, gas or kerosene combustion gas is circulated in the tube, and the temperature of the outer surface of the tube is heated to 200 ° C. to 400 ° C. to generate far-infrared rays. Metal tubes widely used in far-infrared radiation heaters and far-infrared radiation sauna equipment can be used. Since this is a cylindrical tube, there is little risk of distortion or deformation due to expansion or contraction due to heat. Therefore, it is already known that a sufficiently long service life can be obtained even if a very thin metal pipe having a thickness of about 0.3 mm is used. Therefore,
By using such a metal tube, not only is it inexpensive, but also it is possible to obtain a far-infrared radiant electric heater that is very lightweight and easy to handle.

On the other hand, in the present invention, since one set of sheathed heaters 3 is usually provided inside one far-infrared radiation tube 4, it can be used at a lower temperature than before, and
In addition, since the far-infrared radiation tube 4 and the sheathed heater 3 having different temperatures and expansion rates can be freely expanded and contracted without being constrained to each other, there is little danger of distortion or deformation due to heat, and there is an advantage that the durability is excellent. . In summary, it can be said that the far-infrared radiation electric heater of the present invention is inexpensive, light, and has sufficient durability.

As much as possible, and more power energy can be converted to far-infrared rays. That is,
In the embodiment shown, the upper end of the metal tube 4 is
Is closed with a metal plate, and a flange is welded to the bottom of the metal tube 4.
By attaching the flange to the power supply connection box 1,
Therefore, the inside of the metal tube 4 is isolated from the outside air, and both ends of the metal tube are

You. Further, by disposing the sheathed heater 3 inside the far-infrared radiation tube 4 in the far-infrared radiation direction, it is possible to radiate far-infrared rays more efficiently in the far-infrared radiation direction. By providing the sheath heater 3 in the lower half of the far-infrared radiation tube 4, it is possible to more strongly heat the vicinity of the floor when used in a sauna or for heating. It has the effect of reducing the temperature difference between the upper and lower parts of the sauna room and the room to be heated, thereby saving energy by correcting the drawback of air heating, in which the heating temperature is too low and the heating efficiency is poor. Further, the far-infrared radiation electric heater according to the present invention can be used for far-infrared radiation heaters, far-infrared radiation sauna heaters, far-infrared radiation heaters for coating or printing dryers, and various processed food dryers. It can be widely used in various fields, such as far infrared radiation heaters.
