Description

[Detailed Description of the Invention] The present invention relates to wall materials for sauna baths, particularly infrared (far infrared)
This relates to wall materials for line sauna baths.

Conventionally, wall materials for sauna baths have various heat retention and insulation structures to increase heat retention and insulation efficiency. One of them, as shown in Fig. 1, is to form a space (7) between a wooden interior material (5) and an exterior material (6), and to form an aluminum foil (8) within the space (7). ) filled with glass wool (9). In this wall structure, the space (7) and the glass wool (9) filled in the space (7) prevent heat conduction, and the aluminum foil (8) prevents heat rays from coming from the interior material (5). The radiation efficiency is increased by reflecting the radiation. However, in this case, the heat rays that reach the aluminum and minilam foil (8) and are reflected are absorbed by the interior material (5), so the reflection efficiency is low, and the heat absorption by the interior material (5) is low. The disadvantage is that it takes a long time to preheat the sauna bath. In addition, in the case shown in Fig. 2, aluminum foil 00 is used as the interior material (5), but although this has an excellent heat ray reflection effect, it has good thermal conductivity, so it is difficult to protect the human body. There is a drawback that there is a risk of getting burned if you touch this interior material (5).

The present invention has been made in view of the above points, and provides a wall material for sauna baths that does not cause burns and has excellent heat retention and insulation properties that can preheat the sauna bath in a short time. The purpose is to

That is, the present invention has two aluminum plates (1) and an exterior material.
) is filled with a heat insulating material 13) between the aluminum plate (1
) The above object is achieved by a wall material for a sauna bath, which is characterized in that the surface of the sauna bath is coated with a protective sheet +41.

The present invention will be explained in detail below with reference to Examples. Aluminum plate (
As 1), aluminum plate material or aluminum plywood with an aluminum layer formed on the surface can be used, and as shown in Fig. 3, aluminum plate + 11 and exterior material (
2) is filled with a heat insulating material 13) such as glass wool or foamed urethane resin, which is generally used to improve heat insulation (7).A thin protective sheet (4) is completely covered on the surface of the aluminum plate fil. It is covered all over.Protection Sheet H
41 is made of a material with low specific heat and poor thermal conductivity. For example, a polypropylene resin sheet, a synthetic resin with a closed foam layer, a natural board, etc. can be used, and these protective sheets ( By adhering 4) to the surface of the aluminum plate (1) with adhesive etc., the aluminum plate (1) is prevented from being directly exposed to the surface, and when the temperature of the surface of the aluminum plate (ill) rises. But it does prevent you from getting burned. OD in the figure is a core material.

When using the sauna bath wall material thus formed as a sauna bath wall, the wall material is joined as shown in FIG. 4 with the protective sheet (4) inside. Infrared (far-infrared) rays emitted from the light source of the sauna bath hit the aluminum plate (1) on the surface of this wall material and are reflected, so the human body in the sauna bath is heated by direct radiation from the light source. At the same time, the reflected heat rays can also be used to warm the body, making it possible to uniformly warm not only the light source side but the entire human body. In addition, the surface of the aluminum plate (1) is covered with a protective sheet 4) to prevent burns as described above.
4) is made of a thin sheet whose heat capacity is not so large as to cause preheating loss, so it does not absorb a large amount of thermal energy from the light source, and the sauna bath preheating time can be shortened. Furthermore, the protective sheet (4) coated on the surface of the aluminum plate (1) can prevent the aluminum plate (1) from corroding due to sweat and moisture, and can also improve the water resistance of this wall material. It is. In addition, by covering the entire surface of the aluminum plate fil with the protective sheet (4), the flexible protective sheet (4) is interposed between the wall materials when the wall materials are joined, and the gap between the wall materials becomes a trap. It is also possible to perform sealing. In addition, in terms of cost, by using the aluminum plate (1) coated with the protective sheet (4) as the interior material of the wall material, it is cheaper than natural wood veneer.
In addition, it has excellent heat resistance, is lower in price than those using reflective materials such as stainless steel plates, has excellent workability, and is easy to transport because it is made of light clothing.

Note that the protective sheet (4) is a multilayer aluminum plate 1.
It is also possible to form a resin foam on the surface of the 1+ and further form a heat resistant material on the surface.In this way, in addition to the above effects, it has good cushioning properties, a leather touch, and is also aesthetically pleasing. Improved and also aluminum plate (1)
The adhesion to the foam is improved due to the anchoring effect on the foam.
Coupled with the flexibility of No. 41, the durability against heating is the same as above.

FIG. 5 shows another embodiment, in which the heat insulating material 13) is removed and the space between the aluminum plate +1) and the exterior material (2) is made of /%Nicum core α→
It is filled with By filling the inside with this /% nicum core (14) to create a sandwich structure, it is possible to withstand thermal deformation and external loads, and therefore the core material (11) only needs to be small, and the exterior material 12),
The aluminum plate +1) can also be made thinner,
It is inexpensive, lightweight, and easy to transport and install.

As described above, in the present invention, since a heat insulating material is filled between the aluminum plate and the exterior material, the heat insulating material can increase the heat retention and insulation effect, and the radiation efficiency can be increased by reflection by the aluminum plate. Sauna baths made of this wall material have very good thermal efficiency, and since the surface of the aluminum plate is covered with a protective sheet, there is no chance that your skin may come into contact with the surface of the wall material. Since the aluminum plate, which has good direct heat conductivity, is not exposed on the surface, there is no risk of burns, and the heat energy from the light source is not absorbed by the protective sheet, reducing the preheating time of the sauna bath. It can be shortened.
