Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a predetermined infrared radiator to be connected and a frame having an infrared transmitting section, and the infrared ray radiator includes at least a high temperature radiator with a small surface area and a heating element. The present invention relates to an infrared health device characterized by comprising a low temperature radiator having a large surface area and emitting secondary radiation.

Conventionally, acupuncture has been known to alleviate symptoms by improving blood circulation in the affected area or removing congestion, but this has drawbacks such as leaving scars and burns from the needles.

However, methods that utilize infrared rays produce effects similar to those of acupuncture, but by selecting the wavelength, the power to penetrate the affected area can be adjusted, which can actively increase the effect and reduce trauma. It has the advantage of not leaving anything behind.

In the present invention, by giving the radiated infrared rays multiple spectral distributions, it is possible to uniformize the wavelength distribution of the infrared rays over a wide range, especially toward the ultra-far infrared region, thereby increasing the effect and range of application. The purpose is to dramatically increase the number of employees.

An important feature of the present invention is the combination of a high-temperature radiator with a small surface area, a low-temperature radiator with a large surface area, and a secondary radiator that is heated by these and emits secondary radiation as an infrared radiator. be.

In other words, there is Wien's law regarding infrared radiation, and the wavelength at which the radiant energy is maximum is λ.

From the above equations (1) and (2), (a) the wavelength of the emitted infrared rays is inversely proportional to the temperature of the radiator, and (b) the amount of infrared radiation is proportional to the fourth power of the radiator temperature. be understood.

If the actual radiation temperature is 1200〓, then λm is 2.4μ
m, and its radiant energy is 28Kcal/m ²・
It becomes hr. Furthermore, the energy distribution in the short wavelength band from 1.5 μm to 5.0 μm reaches approximately 80%, and such short wavelength infrared rays have poor transmittance to the human body, heating only the surface layer, giving a strong sensation of heat.

Furthermore, when the radiation temperature is lowered to 600〓, λm increases to about 5 μm, the peak becomes very small, and the energy distribution expands to 15 to 20 μm, but the radiation amount decreases.
It will be reduced to less than 1/10, 2Kcal/m ²・hr. Further, infrared rays of 1 to 3 μm are actually necessary from the viewpoint of thermal effects in the surface layer.

However, in the present invention, by using a combination of a small radiation area (surface area) of a high temperature infrared radiator and a large radiation area of a low temperature infrared radiator, the amount of radiation of each wavelength of infrared rays can be adjusted appropriately. This results in a good spectral distribution. The temperature of this radiator can be set within an appropriate temperature range by appropriately changing the resistance value.

FIG. 1 shows one embodiment of the infrared health device of the present invention, and this infrared health device includes an infrared radiator 1 with a high temperature and a small surface area, an infrared radiator 2 with a large surface area and a secondary radiator 6 with a low temperature. It consists of a frame 3 provided inside, and a lens 4 is incorporated in the approximate center of this frame 3.

The inside of the frame 3 is metal plated so that the infrared rays from the radiators 1 and 2 are efficiently radiated to the outside through the lenses.

Furthermore, the end portion of the frame 3 is fitted or integrated into a support portion 5 which also serves as an electrode. By connecting this support portion 5 to a predetermined power source, infrared radiation is performed. Also, the secondary radiator 6 has a net shape, and partially transmits these primary radiations.
absorbs and emits secondary radiation. This secondary radiator 6 is fixed by a support 7 that is not connected to the electrodes.

An example of this control circuit is shown in FIGS. 2 and 3.

By irradiating the affected area with infrared rays at an appropriate distance using this infrared health device, effects such as improving blood circulation can be obtained.

For example, with a total power consumption of about 15W, comfortable effects were obtained with an irradiation time of 5 to 10 minutes at a distance of about 2 to 4 cm.

In the above-mentioned example of the present invention, an example was shown in which two infrared radiators were used in combination, but it is of course possible to combine a larger number of radiators, and the higher the temperature, the smaller the surface. It will be appreciated that by setting .
