いう問題があつた。Problems with the Background Art Generally, an infrared lamp is used as a heat source for a kotatsu.The temperature of the filament of the infrared lamp is approximately 2400°C, and its spectral radiant energy is at a wavelength of 1.1 as shown by line A in Figure 1. It shows a maximum value near μm, and as shown by line B, the wavelength is 5 μm.
The energy below m reaches about 95% of the total energy. However, as is clear from Figures 2 and 3, polyester and acetate, which are the main materials of kotatsu mats, exhibit high transmittance at wavelengths of 5 μm or less; in other words, heat absorption at wavelengths of 5 μm or less is low. It can be said that. Furthermore, the absorbance of cotton and wool is shown in FIGS. 4 and 5, and it can be seen that cotton and wool also have low heat absorption at wavelengths of 5 μm or less. In this way, chemical fibers such as polyester and acetate, and natural fibers such as cotton and wool have poor heat absorption at wavelengths of 5 μm or less, so mats made of these fibers are used as underlays for kotatsu using infrared lamps as the heat source. When used as a kotatsu, heat absorption is extremely poor, and when you put your feet inside the kotatsu,
There was a problem that the matte side was not very warm and felt uncomfortable.

８はこたつぶとん、９はこたつテーブルである。Embodiments of the invention Hereinafter, embodiments of the invention will be described with reference to FIG. 6 and subsequent figures. First, in FIG. 6, 1 is a tower-shaped kotatsu, and this kotatsu 1 has a well-known structure in which an infrared lamp 4 is attached to the lower surface of a top plate 3 supported by four legs 2 (only two are shown). 5
is a guard for the infrared lamp 4. 6 is a kotatsu mat according to the present invention, which is placed under the kotatsu 1. This kotatsu mat 6 is mainly made of chemical fibers such as polyester and acetate, or natural fibers such as cotton and wool. ) is coated with metal oxide 7. The above metal oxide 7 is a composite oxide (Mn, Fe) (Cr, Fe) 2 O4 obtained by calcining manganese dioxide, chromium oxide, and iron oxide at approximately 1200°C, and its spectral emissivity is shown below. As is clear from FIG. 7, it has a high emissivity at all wavelengths, and exhibits an emissivity of 90% or more even at wavelengths of 5 μm or less. A substance with a high emissivity also has a high heat absorption rate, so the kotatsu mat 6 coated with the above-mentioned composite oxide absorbs well the thermal energy radiated from the infrared lamp 4, and the temperature rises appropriately. Therefore, when you put your feet inside the kotatsu 1, you will be warmed from both the top and the bottom.
You can feel comfortable and warm. In addition, in Figure 6,
8 is a kotatsu ton, and 9 is a kotatsu table.
