  Hereinafter, one embodiment of the tatami mat among the laying tools according to the present invention will be specifically described with reference to FIGS. In addition, in the following description, when showing the direction of up, down, left and right, it means up, down, left and right when viewed from the front of the figure.

  As shown in FIG. 1A, the tatami mat T according to this embodiment includes a tatami mat body 1, a heating element 2 that radiates far infrared rays, and a control unit 3 that manages the temperature of the heating element 2. Yes. As shown in FIG. 1A, the tatami body 1 is composed of a tatami floor 10 and a tatami table 11. The tatami floor 10 is formed in a rectangular cross section as shown in FIG. It is formed using knitted rice straw, laminated wood board and cushion material, foam made of synthetic resin, or the like. In addition, as a foam, foams, such as a polyurethane, EVA, crosslinked polyethylene, a polypropylene, polyethylene, urethane foam, a polystyrene foam, etc. are used.

  On the other hand, as shown in FIG. 1A, the tatami table 11 is formed in a rectangular cross-section, and uses a natural rush as a weft thread, or a so-called imitation rush made of a thread of a Japanese paper or a thermoplastic resin. Is formed.

  Thus, in the tatami floor 10 formed in this way, as shown in FIG. 1A, a heating element 2 that radiates far-infrared rays is embedded in a recess 10a formed on the upper surface of the tatami floor 10. Yes. And the tatami surface 11 is arrange | positioned on the upper surface of the tatami floor 10 so that the upper surface of the tatami floor 10 in which the heat generating body 2 is embed | buried in this way, and it sews with hemp thread etc. As a result, the tatami body 1 is formed.

  As shown in FIG. 1B, the heating element 2 is formed in a rectangular cross section and is formed of a plurality of layers. Among the plurality of layers, the lowermost layer is provided with a heat insulating material 20 formed of ceramic such as alumina, silicon nitride, zirconia or ceramic fiber mold, and the upper surface thereof is formed in a coil shape made of a special alloy or the like. The formed heating wire 21 is arranged. And the steel plate 22 excellent in weather resistance and corrosion resistance, such as a galvalume steel plate, is arrange | positioned at the upper surface of the heating wire 21, and the ceramic 23 which radiates | emits far infrared rays is apply | coated to the upper surface.

  Thus, as shown in FIG. 1A, the heating element 2 thus formed is connected to a power supply line 4 to which power is supplied from a household 100V power source. More specifically, the power supply line 4 is connected to the heating wire 21 of the heating element 2 as shown in FIG. As a result, electric power is supplied to the heating wire 21 from the household 100V power supply via the power supply line 4, and the heating wire 21 generates heat. When the heating wire 21 generates heat, the steel plate 22 disposed on the upper surface of the heating wire 21 is heated, and thus far infrared rays are emitted from the ceramic 23 applied to the upper surface of the steel plate 22.

  Thus, when far-infrared rays are emitted from the heating element 2 in this way, the heating elements 2 are embedded in the tatami floor 10, and thus far-infrared rays are emitted from the upper surface of the tatami body 1 (tatami surface 11). As a result, the tatami mat will be warmed. Thereby, the heat retention which is the original function which a tatami has can be improved.

  By the way, as shown in FIG.1 (b), the temperature sensor 21a which detects the temperature of the heating wire 21 is incorporated in the heating wire 21 of the heat generating body 2. As shown in FIG. The temperature data detected by the temperature sensor 21a is output to the control unit 3 as shown in FIG. The control unit 3 receives the temperature data and manages the temperature of the heating element 2, that is, the temperature of the heating wire 21.

  As shown in FIG. 1A, the control unit 3 is disposed on the right side of the upper surface of the tatami body 1 (tatami table 11), and is connected to the power supply line 4. And this control part 3 can perform temperature setting in 10 steps | paragraphs of 15 to 60 degreeC. That is, the temperature can be set in increments of 5 ° C. such that the first step is 15 ° C., the second step is 20 ° C., and the third step is 30 ° C.

  Thus, when power is supplied from the household 100V power supply via the power supply line 4, the control unit 3 formed in this way firstly, as shown in FIG. 2, first, the temperature sensor 21a (FIG. 1 ( The temperature data detected in step b) is received (step S1).

  Next, the control unit 3 confirms whether or not the user has reached a desired temperature of 40 ° C. when the user has set the temperature to 40 ° C., for example, among 10 temperature settings of 15 ° C. to 60 ° C. (Step S2). If the desired temperature (for example, 40 ° C.) has not been reached (step S2: NO), the process returns to step S1 again, and the processes of steps S1 to S2 are repeated until the desired temperature (for example, 40 ° C.) is reached.

  On the other hand, if the desired temperature (for example, 40 ° C.) is reached (step S2: YES), the control unit 3 controls the value of the current flowing through the heating wire 21 so that the desired temperature (for example, 40 ° C.) is maintained. (Step S3). Thereby, the temperature of the heating wire 21 is maintained at a desired temperature (for example, 40 ° C.).

  Thus, according to the present embodiment described above, since the heating element 2 that radiates far infrared rays is embedded in the tatami body 1, far infrared rays are radiated from the tatami body 1. Thereby, a floor heating function is realizable only by laying tatami mat T on a floor.

  The heating element 2 includes a heat insulating material 20 and a heating wire 21 that generates heat when electric power is supplied to the heat insulating material 20, and a ceramic 23 that emits far-infrared rays is applied on the heating wire 21. Therefore, the steel plate 22 is heated only by supplying electric power to the heating wire 21, and thus far infrared rays are emitted from the ceramic 23. Therefore, far infrared rays can be emitted by a simple method.

  Moreover, since the temperature of the heating wire 21 will be maintained by the control part 3 at desired temperature, it can reduce the possibility that the Tatami T will ignite due to overheating. Thereby, since the temperature of the tatami mat T is maintained at a desired temperature, only a light comforter is warmed. In addition, if you set the desired temperature high after getting up, that temperature will be maintained, so the mattress laid on the tatami body 1 will become soft and mite extermination in about 3 to 5 hours Can do.

  Note that the tatami body 1 described in the present embodiment is merely an example, and any tatami body configuration may be used as long as the heating element 2 can be embedded.

  On the other hand, the mat of the mats according to the present invention has the same configuration as the tatami mat described above. That is, as shown in FIG. 3, the mat M according to this embodiment includes a mat body 100, a heating element 2 that radiates far infrared rays, and a control unit 3 that manages the temperature of the heating element 2. . The heating element 2 is embedded in a hole 100a formed in the mat body 100 as shown in FIG. Further, the heating element 2 is temperature-controlled by the control unit 3 in the same manner as the tatami mat described above.

  Thus, the mat M according to the present embodiment described above has the same configuration as the tatami mat T described above, and therefore has the same operational effects as the tatami T.

  The mat body 100 described in the present embodiment is merely an example, and any mat body configuration may be used as long as the heating element 2 can be embedded.
