Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a far-infrared radiant heater that uses far-infrared rays as a heating source in a low-temperature range, and a pine mattress that uses the same.

[Prior Art] Conventionally, as a device for generating heat in a low temperature range, a resistance heating wire has been arranged in a flat plate shape. There are electric blankets, electric pine mattresses, etc.

[Problems to be Solved by the Invention] Conventionally, electric blankets, electric mattresses, and other heat sources have been made of nickel-chromium wires, copper-nickel wires, etc., and have been used to simply warm the surface of the body.

Infrared rays have a wide range of wavelengths from 0.76 to too many microns. This is classified by wavelength.

0.76-1.5 micron near infrared, 1.5-3.0
Micron is mid-infrared, 3.0~too.

Micron radiation is called far infrared rays. Far-infrared rays are radiation-type heat propagation, and are highly efficient because they pass through layers of air and textiles to reach the heated object in a straight line.9 Also, most of the organic matter contained in the human body has wavelengths in the far-infrared range. Because they roughly match, there is little reflection or transmission of energy, and most of it is absorbed internally.

High efficiency in energy exchange. Furthermore, far-infrared rays reach deep into organic matter, and the frequency of far-infrared rays (the reciprocal of the wavelength)
This becomes a resonance movement with the natural frequency of the organic substance (molecule), and internal self-heating occurs.

The human body is made up of such organic matter, so when it is irradiated with far infrared rays, the temperature rises deep inside the human body.In other words, the temperature rises almost simultaneously inside and outside the organic matter. .

Therefore, no problems occur due to temperature differences between inside and outside.

Pine tress using far-infrared rays has effects that cannot be seen with conventional pine tress.

[Means for Solving the Problems] Therefore, in view of the above-mentioned conventional problems, the present inventor conducted intensive research and arrived at the present invention.

Furthermore, according to one aspect of the present invention, the above-mentioned core is formed by rolling and connecting the closed cell projection sheet into a roll.

A pine tress using far-infrared rays is provided, in which the far-infrared radiant heater described above is embedded and assembled into a cover.
