A specific example of the far-infrared radiation layer 17 will be described below.
It is as follows. In other words, aluminum peroxide, which is Al ₂ O ₃ , is formed by being oxidized and dispersed and welded, and the aluminum peroxide plate is spontaneously colored with sulfuric acid or hydrobromic acid for about 1 hour 30 minutes. In the color forming process, a metal atom compound in a submicron unit is formed in the housing 1.
Oxidized and dispersed on the surface of the aluminum plate, which is 0, and welded, and a gray color close to black is visually recognized with visible light. In addition,
In forming the far-infrared radiating layer 17, it is preferable that the far-infrared radiating layer 17 is manufactured by using a product name "Super Ray" manufactured by Sky Aluminum Co., Ltd.

Reference numeral 18 denotes a cylindrical socket supporting body, which is an opening 10 provided on the bottom surface 10a of the housing 10.
b, the end thereof is inserted, and the end is turned back and the bottom surface 1 of the housing 10 is welded or caulked.
On the protruding end side, a socket portion 19 of a standard size (D1, L1 in FIG. 6) as conventionally used is mounted while being insulated from the socket support body 18. is there.

The socket 19 may be selected from various commonly used ones. In this embodiment, the socket 19 is formed of an insulating ceramic material or the like. A metal base is attached to the small diameter part of the, and it is possible to conduct electricity while ensuring insulation.

In the socket supporting body 18, there are inserted conducting wires 20a and 20b for electrically connecting the heating element 13 and the socket portion 19 to each other. One of the conducting wires 20a, 20b is connected to the starting end and the ending side of the socket, and the conducting wires 20a, 20b are connected to the conducting electrodes 19b, 19c of the socket portion 19. Reference numeral 19a denotes a screw portion provided on the outer periphery of the socket portion 19.

The far-infrared radiation sphere is compatible with the conventional infrared drying bulb shown in FIG.
The entire length L and width D of the socket portion 19 are, of course, substantially the same.

Next, FIG. 4 shows the experimental results of the far-infrared radiation sphere. The measuring device used in this experiment was "JEOL JI
R-100 Fourier transform infrared spectrophotometer ". Reference: 80 ° and 160 °, measurement temperature;
The test was performed at 148 ° C., the number of times of integration: 200 times, and the detector: MCT. As is clear from the graph of FIG. 3, the one according to the present invention has a distance of 2.5 μ or more (1/2200 = 0.
45) can be radiated stably and efficiently.

Next, a far-infrared radiation sphere according to the present invention,
FIG. 5 shows a comparative example of a conventionally used infrared drying bulb. When measured with a radiation thermometer, as shown in the figure,
In the case of a 250 W infrared drying lamp, the counterpart object located at a position of 300 mm is set to 160 °, while that at a position of 500 mm is set to 140 °. On the other hand, the far-infrared radiant sphere has a power of 63 W, and the counterpart object at the position of 300 mm is set to 160 °, and 160 ° even at the position of 500 mm.
And

The radiation width of the conventional infrared drying bulb is H because the filament is used. However, the far infrared radiation sphere is radiated from almost the entire surface of the far infrared radiation layer 17, and thus has a width H 1. And H <H1.

As described above, the far-infrared radiating sphere according to the present invention, when a certain amount of electricity is applied to the heating element 13 of the electromagnetic wave amplification board 12 built in the housing 10,
The heating element 13 starts to generate heat, and the far-infrared ray radiating layer 17 formed on the surface of the housing 10 is heated with the heat generation, and is also transferred from the heating element 13 side to the housing 10 via the conducting wires 16a and 16b. 0.006-0.008
mA current flows.

For this reason, 10 in the far-infrared radiation layer 17
^-14 / 1 cm (the amount is affected by the power supply amount) ³ or more free electrons move randomly, far infrared rays are radiated as electromagnetic waves 2.5μ beyond the far-infrared emitting layer 17 when accompanied by accelerated quantum . Note that the relationship with the appropriate wavelength depending on the amount of electricity is
According to this embodiment, 55W-about 6.46μ, 63W-
About 6.24μ, 81W-about 5.99μ, 105W-about
It is set to 5.5 μ.

Next, the radiation of the electromagnetic wave propagates in the air without being blocked by airflow, penetrates into the elemental compounds constituting the substance / object, and has a molecular weight having an electric charge (amount of electrons) (Avocado's law). Natural frequency (about 4.5 billion times / second or more)
Conforms to and releases vibrational heat due to friction between element molecules,
Dries and cures efficiently at low temperatures.

That is, the radiated electromagnetic wave conforms to a wavelength absorption band of 2.5 μ or more, which is the wavelength absorption band of atoms and molecules constituting the object, and can favorably promote the vibration inherent to the molecules in the atoms of the object. Thus, efficient drying can be performed.

The absorption wavelength in a substance or an object is concentrated in the band of 3 to 20 μm. However, since the conventional infrared drying lamp has a near-infrared ray having a radiation wavelength of 2.5 μm or less, the absorption of the intrinsic molecules of the substance or the object is possible. The spectrum has a low precision. However, since the far-infrared radiation sphere causes the object to be heated to absorb electromagnetic waves in the far-infrared wave band, as described above, the unique element molecules that constitute the substance / object, such as paint, vibrate more than 4.5 billion times per second. It is excited and instantly exchanged with heat in a substance or object to dry and harden.

A far-infrared radiation layer 17 is laminated on the front surface of the housing 10 by anodizing, which is an anodizing process, and a socket portion 19 of the same size as the conventional product is provided on the back surface of the housing 10. Since it is configured to be provided, it is harder to be damaged as compared with the conventional product made of the glass ball 1 and has compatibility with the conventional product, so that it can be used without modifying existing equipment. .

An insulating plate 14 made of a Teflon-based polyimide resin sheet or a black mica thin plate is disposed on the upper surface side of the heating element 13 to form an electromagnetic wave amplification substrate 12, and this electromagnetic wave amplification substrate is formed. Since the insulation between the heating element 13 and the housing 10 is ensured by the above-described members, the weight can be reduced, and the production can be performed with good mass productivity and low cost.

Next, FIG. 7 shows another embodiment of the present invention. That is, the far-infrared radiation layer 1
Instead of providing the socket supporting body 18 as in the above-described embodiment, a connection terminal 30 for connecting to an external power supply that allows a lead wire (not shown) to be detachable with a bolt 30a or the like is provided on the back surface side of the housing 10 having the connector 7. A mounting portion 31 is provided and has a U-shaped cross section and can be attached to and detached from other members. The shape of the mounting portion 31 may be any shape as long as the above-described function is achieved.

Therefore, according to the far-infrared radiation sphere, the same effects as those of the above embodiment can be obtained,
It can be installed anywhere.

The material compatibility of the dried substance / object is 80% or more. 2. Energy consumption can be reduced by 70% in terms of electricity consumption. 3. The surface emissivity is as high as 31.6%. 4. In terms of durability, the performance can be improved by a factor of 5 or more. 5. The finish is more beautiful. 6. Insulation between the housing 10 and the heating element 13 can be secured with good mass productivity and at low cost, and the weight can be reduced.

[0038]

As described above, according to the present invention, the energization of the heating element built in the housing causes the farther infrared radiation layer formed on the surface of the housing to be at least 2.5 μm away from the far-infrared radiation layer.
