Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an infrared therapy device. More specifically, the present invention relates to an infrared therapy device that uses a carbon film as a heating means for an infrared radiator, thereby making the device safer, lower in cost, longer in life, and smaller in size.

[Conventional technology]

Infrared rays have been used for the purpose of promoting blood circulation, alleviating pain such as neuralgia and muscle pain, and recovering from fatigue. In addition to the above, infrared rays are also effective in treating athlete's foot, for example, and the inventors conducted an experiment to confirm this effectiveness.
This is confirmed by the fact that the bacteria change color and deform, and their growth is inhibited.

When using infrared rays as described above, zirconium ceramics or germanium ceramics are used as means for emitting infrared rays, and these ceramics are heated with a nichrome wire built into the ceramic or another heat source to emit infrared rays. It radiates.

[Problem that the invention seeks to solve]

However, among these conventional devices, those that use nichrome wire as a heating source not only have problems with the reliability and lifespan of the device because the nichrome wire may rust or break. However, since the nichrome wire is built-in, the size of the device increases.Furthermore, since the nichrome wire is built-in, the cost of assembling the device increases, which in turn increases the cost of the entire device. On the other hand, a device in which a heat source is provided separately from the infrared radiation means has the problem that the separate heat source increases the size of the device and increases the cost of the device.

In view of the above-mentioned points, an object of the present invention is to provide an infrared therapy device that can emit infrared rays simply and reliably, and can be used stably over a long period of time.

[Means for solving problems]

The infrared therapy device of the present invention is characterized by comprising a plate-shaped infrared radiator and a carbon film coated on one side of the radiator in the form of a film, which heats the radiator when energized. There is.

[For production]

In the infrared therapy device of the present invention, the infrared radiator is heated by energizing a carbon film coated on one side of the radiator, and emits infrared rays from its surface.

〔Example〕

Next, the present invention will be explained in detail based on the drawings.

Fig. 1 is a schematic cross-sectional explanatory diagram showing one embodiment of the infrared therapy device of the present invention, Fig. 2 is an explanatory diagram of the embodiment shown in Fig. 1 viewed from above, and Fig. 3 (ω~ (C) is an explanatory diagram showing a part for supplying electricity to the carbon film, and FIGS. 4 to 6 are schematic explanatory diagrams showing other embodiments of the infrared therapy device of the present invention.

In Figures 1 and 2, (A) is an embodiment of the infrared therapy device of the present invention, which is a type of therapy device that emits infrared rays to the soles of the feet. (1) is an infrared radiator, one side of which (
A carbon film (2) is applied to the surface opposite to the feet. (3) is a footrest that prevents the feet from coming into direct contact with the radiator (1) and maintains a distance between the affected area and the surface of the infrared radiator to ensure a good therapeutic effect; It is attached to an outer frame (4) that houses an infrared radiator (1) and a heat insulating material (5) that prevents heat transfer to the outside of the device. This footrest bar (3) may be provided not only in the direction shown in FIG. 2 but also in a direction perpendicular thereto, or may be arranged in a grid pattern. This footrest (3) is further
It may be of a fixed type, or it may be of a type in which the distance to the infrared radiator surface can be adjusted. (6)
is a temperature detection means for detecting the surface temperature of the infrared radiator (1).

Further, (7) is a temperature regulator that adjusts the state of energization to the carbon film (2) based on the signal from the temperature detection means.

Any infrared radiator (1) can be used as long as it can emit infrared rays with a long wavelength when heated, but in terms of radiation efficiency, workability, etc.
Ceramics with high emissivity in the far-infrared region, such as lithium oxide ceramics, zirconium ceramics, and germanium ceramics, are excellent. Here, infrared rays refer to infrared rays in a broad sense, including near infrared rays and far infrared rays, and it is presumed that most of the effects achieved by the treatment device of the present invention are due to far infrared rays among the above infrared rays. Of course, other effects of infrared rays can also be expected. The thickness of the infrared radiator (1) may be appropriately selected in consideration of the heating effect, strength, application location of the treatment device, etc., but the approximate thickness is approximately 5 to 20III11. In addition, when using ceramics as the infrared emitter (1), glaze is applied to the surface of the affected area such as the foot or lower back to protect the ceramic surface and improve the aesthetic appearance (approximately 4
After coating (approximately 0 times), baking may be performed.

The carbon film (2) can be obtained by applying an aqueous suspension of carbon to one side of the infrared radiator (1) by spraying or the like and drying it by heating.

More specifically, for example, Bunny Height ■-174 (
Product name. Spray a graphite aqueous solution such as Nippon Graphite's aqueous graphite solution evenly onto the unglazed ceramic part at a pressure of about 4 kg/cm2, dry it in a thermostat at 100±5℃ for about 5 minutes, fire it in a firing furnace, and then A carbon film can be formed by cooling the collected material in air. In that case, the firing temperature is about 30-80℃ from room temperature to 450℃.
The temperature is increased at a gradient of 1 minute and then maintained at 450°C for 10 minutes.

After forming the carbon film, the carbon film can be coated with glass frit and fired at the firing temperature of glass frit, thereby further increasing the stability of the carbon film.

The thickness of the carbon film is not particularly limited, but is approximately 20~
A standard value is 100ρ, and 30 to 50ρ is particularly preferable.

The outer frame (4) may be selected from materials such as stainless steel, colored iron plate, and heat-resistant resin in consideration of strength, aesthetics, heat resistance, and the like.

FIG. 3 (ω to (C) is an explanatory diagram showing the current-carrying part to the carbon film, where (8) is a terminal, (9) is a bolt, and η is a nut. The terminal (8) is a bolt ( 9) and Natsuto (
It is electrically connected to the carbon membrane (2) by a washer O1) to ensure the connection.

In order to increase the contact area, the copper plate 0 is used as shown in Figure 3).
21 may be used by sandwiching it between the terminal (8) and the carbon film (2), or it may be used by sandwiching it between the terminal (8) and the carbon film (2).
As shown in C), the peripheral portion (13) of the terminal (8) may be coated with silver or the like.

4 to 6 are schematic illustrations showing other embodiments of the infrared therapy device of the present invention. The treatment device shown in FIG. 4 allows the vertical position of the infrared ray emitting part and the direction of the emitting surface to be changed as appropriate, and can be suitably used for the waist or shoulders. The treatment device shown in FIG. 5 is a band-type treatment device, and is used by fixing the treatment device to the waist or the like using the band side. The treatment device shown in FIG. 6 is a treatment device for childbirth and is mainly used for the treatment of hemorrhoids. In this case, from the viewpoint of ease of use, it is preferable to provide a pedestal on top of the treatment device and use it by sitting on it.

In the infrared therapy device (A) of the present invention, the infrared radiator (
The surface temperature of the affected area in 1) is controlled to a predetermined temperature by a temperature detection means (6), a temperature regulator (7), etc., and it is preferable that the surface temperature is approximately 50 to 200°C. If the surface temperature is higher than 200° C., it is not preferable because there is a risk that near-infrared radiation will increase and cause low-temperature burns or cataracts, as well as cracks in the infrared radiator. Conversely, if the surface temperature is lower than 50° C., far infrared rays, which are particularly effective for treatment, will no longer be emitted and the desired therapeutic effect will not be achieved.

According to the infrared therapy device of the present invention, it is possible to have not only a blood circulation promoting effect, a pine surge effect, and a pain relief effect, but also a treatment effect for so-called athlete's foot.

Although the principle behind this therapeutic effect on athlete's foot, ie, the inhibitory effect on the growth of the white fungus that causes athlete's foot, has not yet been fully elucidated, it is generally presumed to be as follows. In other words,
When far-infrared rays are irradiated to the affected area where white fungi (called athlete's foot, shirakumobacterium, or ringworm depending on the location) are nested, the far-infrared rays have the property of penetrating the inside of the body to a depth of about 40 degrees. Therefore, it is presumed that this is due to a process in which the keratin (scleroprotein) layer (about 0.1 to 0.5 square meters thick) of the epithelial cells is excited, causing a disturbance in the metabolism of the bacteria.

〔Effect of the invention〕

As explained above, the present invention uses the carbon film coated on the infrared radiator as a heating means for the infrared radiator, so it is not only possible to perform stable heating over a long period of time, but also to achieve better heating than conventional devices. This makes it possible to downsize the device and reduce costs.
