DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating tatami mat having a heating function.

[0002]

2. Description of the Related Art As a conventional tatami mat, for example, an insulated tatami mat in which a tatami mat, a straw, a resin foam, a straw, and a tatami mat are sequentially laminated from the front side is known.
This insulated tatami has the feeling of a straw and is excellent in heat insulation, moisture proof, heat retention and the like by using a resin foam. However, since the tatami itself does not have a heating function, it was necessary to use another heating device. For example, a floor heating device in which a heating element is embedded in a carpet is known as a device for heating a tatami surface.

[0003] At home and the like, the above-mentioned carpet-type heater is laid on a tatami mat to heat the tatami mat. However, carpet-type heating appliances have the drawback that they cover the surface of the tatami, impairing the feel of the surface of the tatami, and that mites easily propagate. Also, carpet-type heaters are usually
There is a drawback that it is simply placed on the tatami mat and is not firmly fixed to the tatami mat surface, so that the position shifts during use and the usability is poor.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and has as its object to provide a heating tatami in which the tatami itself has a heating function.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a heating tatami having a sheet heating element between a tatami mat and a resin foam, wherein the sheet heating element is provided between the tatami mat and the sheet heating element. The gist of the present invention is a heating tatami, which is capable of transmitting heat to a tatami surface and is provided with a heat transfer protection layer having a function of protecting a planar heating element.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. The heating tatami 1 of the embodiment shown in FIG. 1 and FIG.
For example, a tatami mat 2 such as an rush, a heat transfer protection layer 3, a planar heating element 4, a resin foam 5, a straw or insulation board 6, and a back sheet 7 are sequentially laminated from the front side. As shown in FIG. 1 and FIG. 2, the heating tatami 1 of the present invention has a planar heating element 4 embedded at least inside the tatami 1 and is located between the tatami mat 2 and the resin foam 5.
The heat transfer protection layer 3 is provided between the sheet heating element 4 and the tatami mat 2.

[0007] The tatami mat 2 is made of a known tatami mat such as rush. The heat transfer protection layer 3 has a sheet heating element protection function capable of protecting the sheet heating element 4 when the material itself has elasticity and receives an impact or the like from the front side of the tatami mat, What is necessary is just to be able to transmit the heat of the sheet heating element 4 to the tatami table 2. As a specific material of the heat transfer protection layer 3, a material in which a through hole 8 is provided in a cork, a resin plate, a low-foamed resin foam, or the like by punching or the like so as to penetrate the front and back surfaces thereof (FIG. 3). No. Further, as the heat transfer protection layer 3, a foam or the like in which a void communicating between the front and the back can be used. Such a foam can transmit the heat of the planar heating element to the tatami surface without providing the through-hole 8, and thus can be used as it is.

The material of the heat transfer protective layer 3 is preferably a sheet-shaped cork having through holes 8 formed on the front and back sides by punching or the like in terms of hardness, cushioning property, and feel of the tatami mat. Further, as shown in FIG. 3, the cork surface has irregularities, so that when the tatami table 2 is laminated, the tatami table 2 and the cork 3
Is formed between them. The air gap 9 has a heat insulating effect of air, and the heating efficiency is further improved. In addition, tatami table 2
The cushioning property of the tatami mat surface is improved due to the unevenness between the heat transfer protective layer 3 and the heat transfer protective layer 3.

In the case of a material having no unevenness on the surface, such as a non-foamed body of a plastic plate or a foamed body having a low expansion ratio, as a material of the heat transfer protective layer 3, embossing or other known means is used. By forming the concavities and convexities, the same effect as that of the above cork can be obtained.

As the heat transfer protection layer, a sheet formed by knitting cork having a width of about 2 cm may be used.
Compared with a normal cork sheet, this sheet has a large number of voids formed in advance, so there is no need to particularly form a through hole, and the effect of cushioning and heat transfer is great.

In the heating tatami 1 of the present invention, as the material such as the tatami mat 2, the resin foam 5, etc., the materials used for conventionally known heat insulating tatami mats can be used. For example, as the resin foam 5, a foam having closed cells such as a polystyrene foam and a polyolefin foam is used.

As the sheet heating element 4, a known heating element formed in a sheet shape can be used. For example, as shown in FIG. 4, the planar heating element is provided with two comb-shaped electrodes 12 and 13 on a polyester film or the like by, for example, printing so that they are alternately arranged. 1
For example, the semiconductor 14 is provided by printing in a streak shape using carbon ink or the like between the three, and a polyester film or the like is laminated thereon to form a thin sheet-shaped heating element. Contacts 15 for connecting a power cord 16 are provided at the ends of the electrodes 12 and 13.
An example of such a planar heating element is “Fever” (trade name of Nippon Special Industries Co., Ltd.). Incidentally, 17
Is an insertion plug.

The heating tatami 1 of the present invention can be used by connecting a plurality of tatami mats. For example, the sheet heating elements of each heating tatami may be wired to supply power to each heating tatami from one plug.

[0014]

According to the heating tatami of the present invention, when the sheet heating element 4 is energized by inserting an insertion plug connected to the sheet heating element of the heat insulating tatami 1 into an outlet or the like, the heating element 4 generates heat.
The heat of the planar heating element 4 is transmitted to the front of the tatami mat through the voids or through-holes of the heat transfer protection layer 3 thereabove, and the tatami mat surface is warmed. Due to its elasticity, the heat transfer protection layer 3 reduces shocks and the like applied from the tatami surface and reliably protects the lower surface heating element 4.

[0015]

As described above, in the heating tatami of the present invention, the planar heating element provided between the tatami mat and the resin foam generates heat,
Since the tatami mat itself has a heating function, a carpet-type floor heating device is unnecessary, and the drawbacks of the carpet-type floor heating device can be solved.

Further, since the heat transfer protection layer is provided between the tatami mat and the sheet heating element, the heat of the sheet heating element can be smoothly transmitted to the tatami mat and various impacts can be applied from the tatami mat side. There is no danger that the sheet heating element will be damaged even if it is received, and it can be used safely. For example, it can be used optimally when caring for the elderly, etc., from the viewpoints of having no drawbacks such as a carpet type heating device, ease of use, safety, hygiene and the like.
