BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami floor for floor heating, and more particularly to an arrangement for conducting heat from a heat source to a tatami floor.

[0002]

2. Description of the Related Art Floor heating has been widely used as a comfortable heating system which can obtain a uniform temperature and does not pollute the air in a room. At the same time, floor heating installation locations are no longer limited to Western-style rooms, and installations in Japanese-style rooms are increasing rapidly. When installing in a Japanese-style room, a heat source will be provided below or inside the tatami mat.

[0003] By the way, the tatami floor conventionally manufactured in the past is called a straw floor, and has a structure in which a bundle of straws is squeezed and knitted several times, and has a considerable weight. . On the other hand, recently, lightweight tatami floors in which a foamed resin material is used in combination with a part of a core material have also been developed. Each of these tatami floors has an excellent heat insulation performance, which is an important function of the tatami mat. When laid on a floor heating facility, heat from the heat source is shut off. Therefore, the floor heating effect cannot be exerted on the tatami floor as described above.

There are various types of tatami mats for floor heating, such as a thin tatami mat taking into consideration the rise in temperature, and a tatami mat using an insulation board or a thin plywood board which is relatively resistant to heat. Is devised.
However, both are basically insulation materials,
Alternatively, it is a material having low thermal conductivity or thermal efficiency must be significantly impaired. In addition, a thin tatami mat which gives priority to rising temperature has a problem that the tatami mat warps due to heat, and furthermore, since it is thin, there is a problem that the tatami mat lacks the texture and volume and the sitting comfort is poor.

[0005]

As described above, a dedicated tatami mat for floor heating is indispensable for floor heating in a Japanese-style room. However, conventional tatami floor heating has a thermal insulation function on the tatami floor itself, so even if it is thin, its thermal efficiency is poor, and tatami mats such as insulation boards are warped by thinning. Problems, textures,
There were problems such as lack of volume.

On the other hand, Japanese Utility Model Laid-Open No. 57-183335
The Japanese Patent Publication No. 1-2005 discloses that the thermal conductivity from the lower side of the tatami to the upper side is increased.
Tatami floors made of insulating material such as synthetic foam
Is covered with a heat transfer material, for example, aluminum foil.
A tatami mat for heat transfer in which the top and bottom of aluminum foil are connected by the same heat transfer material
It is listed. However, in this way, heat transfer materials are assembled in a tatami floor.
This leads to an increase in the number of manufacturing steps. Therefore, gold
When assembling heat transfer materials made of metal onto tatami floors,
The issue is how to improve the performance.

[0007] The present invention is intended to solve such problems, and is excellent in thermal conductivity, can be made sufficiently thick, and has the same texture and volume as conventional tatami mats not used for floor heating. An object of the present invention is to provide a tatami floor for floor heating which is obtained and excellent in manufacturability .

[0008]

In order to achieve the above object, the tatami floor for floor heating according to the present invention has a thin metal sheet along the lower surface of the tatami mat.

[0009]

[Function] In the tatami floor for floor heating of the present invention, when a tatami mat using the tatami floor is laid on the floor heating facility and used for floor heating, heat from the heat source of the floor heating facility first receives heat along the lower surface of the tatami mat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. First, the configuration of the panel-shaped tatami floor 1 will be described with reference to FIG. Reference numeral 2 denotes a heat transfer plate, and the heat transfer plate 2 is formed by folding a single long metal thin plate. The material is aluminum having excellent thermal conductivity, but the thickness is slightly thicker than the aluminum foil and can be easily bent. The heat transfer plate 2 is folded in a sectional shape in which an upward regular triangle and a downward regular triangle are alternately and continuously arranged at equal intervals. Thus, the heat transfer plate 2 has a structure in which the heat receiving portion 3 along the entire lower surface of the tatami floor 1 and the heat radiating portion 4 along the entire upper surface of the tatami floor 1 are integrally connected by the heat transfer portion 5. In addition, only on both sides of the tatami floor 1, the heat transfer plate 2
Has a right-angled triangular cross section, and has a vertical side surface portion 6. Heat transfer plate 2 thus folded
Is bonded so that kraft paper is wrapped from the outside, and the heat transfer plate 2 is fixed by a mold 7 made of the kraft paper. Further, in this heat transfer plate 2, a hollow urethane foam, which is a foamed resin material, is filled in a hollow portion having a triangular cross section between the heat receiving portion 3 and the heat dissipating portion 4 and a pair of adjacent heat transfer portions 5. Thus , the core material 8 is formed. The rigid urethane foam has excellent adhesion to a metal such as aluminum, and the respective portions of the heat transfer plate 2 are adhered to each other by the filled rigid urethane foam, and are integrated with the core material 8. In addition, the thickness of the tatami floor 1 is about 55 to 60 mm.

The tatami floor 1 constructed as described above is cut as needed. As shown in FIG. 2, a moisture-proof paper 11 is stretched on the lower surface (back surface) of the tatami floor 1 and the upper surface (front surface). ), A tatami mat 13 made of rush is stretched through a nonwoven fabric 12 as a cushion. These tatami mats 13 and the like are sewn together with the tatami edges 14 around the tatami floor 1. This sewing may be manual or mechanical sewing. The heat transfer plate 2
Is made of an aluminum thin plate having a thickness slightly larger than the aluminum foil, so that the cutting and sewing can be freely performed without interfering with the cutting and sewing. Therefore, the tatami mat table 13 can be freely replaced like a normal tatami mat. Further, the tatami mat 16 thus formed is laid on the heat source 21 of the floor heating facility. The heat source 21 is, for example, a rubber sheet

Moreover, the heat receiving portion 3 and the heat radiating portion 4 extend along the entire lower surface and the entire upper surface of the tatami floor 1, respectively, and the heat transfer portion 5 between the heat receiving portion 3 and the heat radiating portion 4 is provided.
Are located at equal intervals, heat is uniformly transmitted from the heat source 21 to the heat radiating section 4, and the room can be heated at a uniform temperature. As a result, not only can energy be used effectively,
Can be made sufficiently thick. Therefore, the same thickness as that of the conventional tatami mat for floor heating can be ensured, and the texture and volume that are the same as those of the conventional tatami mat for non-floor heating can be obtained. Further, since the core material 8 of the tatami floor 1 is made of a rigid foamed polyurethane foam, the non-woven fabric 12
Together with that, the sitting comfort is soft and good. In addition, since the core member 8 is also made of the rigid foamed polyurethane foam, it can sufficiently withstand not only human loads but also large loads such as furniture and furniture.
Furthermore, the tatami mats 16 do not warp when subjected to heat. Further, as in the first embodiment, it is relatively easy to bend one metal sheet into a heat transfer plate 2 having a predetermined shape. Workability including the handling is also improved.
