DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, a tatami mat for floor heating can efficiently transfer heat from a heat source disposed below the tatami mat to a top surface of the tatami mat with a normal thickness. In general, the thickness is set to be relatively thin because it cannot be performed.

[0003] Therefore, the conventional tatami mat for floor heating has a drawback that the sitting comfort is very poor because the tatami mat is thinner than a normal tatami mat.

[0004] Originally, tatami mats have been set in thickness based on experience from ancient times in consideration of sitting comfort and the like. Is inevitable.

[0005] Activating the floor heating is only for a short period of time during the year when it is cold, and it is overturned that the sitting comfort is degraded considering only the floor heating. The reason is that the period during which floor heating is activated is small, and the period during which it functions as a normal tatami mat is longer because the cold period of the year is small.

The present invention solves the above-mentioned problems, and provides a tatami mat for floor heating that has good heat conductivity for floor heating while maintaining the same sitting comfort as a normal tatami mat. This is a technical issue.

[0007]

The gist of the present invention will be described with reference to the accompanying drawings.

A floor heating tatami mat having a tatami mat surface 4 provided on the surface of a core material 1, wherein the core material 1 is stitched with a heat transfer member 3 having converged ultrafine wires having good heat conductivity. It relates to a tatami mat for heating.

[0009]

The heat of the floor heating is transmitted in the order of the core 1, the heat transfer member 3 where the core 1 is sewn, and the mat 4.

[0010]

FIGS. 1, 2 and 3 show a first embodiment of the present invention, and FIG. 4 shows a second embodiment of the present invention, which will be described below.

Reference numeral 1 denotes a core material having the same structure as that of a normal tatami mat. There are two types of tatami mats, a chemical tatami mat in which the core material 1 is formed of wood chips, and a straw tatami mat in which the core material 1 is formed of straw. The tatami mat of the present embodiment naturally includes both.

Reference numeral 2 denotes a covering member, in this case a copper or aluminum foil adhesive tape having an adhesive applied to the back surface. This adhesive tape is provided with an appropriate number of small holes for the purpose of ensuring air permeability. Heat is uniformly transmitted by the covering member 2. Reference numeral 3 denotes a heat transfer member, in which in this case, as shown in FIG. 3, approximately 50 copper or aluminum yarns having a diameter of 50 μm are converged and twisted.

Reference numeral 4 denotes a tatami table, which has the same structure as a normal tatami table.

Reference numeral 5 denotes a floor provided with an appropriate heating member for floor heating, and reference numeral 6 denotes a tatami edge. Since the present embodiment has the above configuration, the core 1 is sewed by the heat transfer member 3 in the usual manner, and then a copper or aluminum adhesive tape is adhered to the front and back of the core 1. A tatami mat for floor heating having a thickness of about 40 mm is created by the work of attaching the tatami table 4 by a conventional method.

Therefore, according to the tatami mat according to the present embodiment, the tatami mat does not become particularly thin because it is used for floor heating, and because it has the same thickness as a normal tatami mat, the sitting comfort is not impaired. 3, the heat transfer member 3 has a good heat transfer property. Further, since the heat transfer member 3 is made by converging a yarn having a diameter of 50 μm, when the user sits on the tatami mat, the heat transfer member 3 is easily crushed and the core 1 The heat transfer member 3 does not transmit to the occupant as a foreign substance sensation, and the heat transfer member 3 is crushed and spread by the action of a load, so that the heat dissipation surface is widened. Good heat transfer.

The thickness and the sewing pitch of the heat transfer member 3 are appropriately designed in consideration of heat transfer.

FIG. 4 is a cross-sectional view of the second embodiment, in which a copper or aluminum adhesive tape is double-adhered to improve the heat transfer property. The same is true.

[0018]

As described above, the present invention provides a tatami mat for floor heating with good heat transfer and good sitting comfort.
