  In this patent document, a plurality of heat generating sheets are sandwiched between a floor base material (heat insulating material) and the floor material, and installed between the floor base material and the floor material on site. In addition, there is a problem that the installation cost increases because it requires materials and labor to lay a heat generating sheet or to engrave a groove in the floor base material to escape the lead of the heat generating sheet.

  Accordingly, an object of the present invention is to provide a floor heating apparatus that can be installed at low cost by constructing it so that floor heating is possible by simply laying it on the floor of a room.

In order to achieve the above-described object, the present invention provides a sheet-like sheet comprising a floor-stabilizing sheet mainly composed of iron powder and asphalt laid on the floor, and a plurality of sheet-like heaters laid on the upper surface of the floor-stabilizing sheet. A heating element and a floor sheet covering the upper surface of the planar heating element, and by adhering all or a part of the floor stabilizing sheet, the planar heating element and the floor sheet to each other, the size of each room In the case of using a plurality of the floor stabilizing sheet and the floor sheet, the adjacent sheets are connected with a heat-resistant tape, and the floor stabilizing sheet and The floor sheet is disposed in a direction in which the heat-resistant tapes intersect each other .

  In this case, according to the present invention, the floor stabilizing sheet can be formed into a sheet shape by a rolling roller after uniformly kneading iron powder and asphalt.

  According to the present invention, the floor stabilizing sheet, the planar heating element, and the floor sheet can be bonded to each other using a heat-resistant double-sided tape.

  Further, according to the present invention, the edge of the sheet-like floor heating device can be configured by directly bonding the edges of the floor stabilizing sheet and the floor sheet.

  Since the floor heating apparatus according to the present invention is configured as a single sheet having flexibility, floor heating is possible by simply laying the floor on the floor and connecting it to a power source without modifying the existing floor. In this case, if the floor stabilizing sheet is composed of a certain amount of weight, the entire sheet is stabilized on the floor, and there is an effect that the sheet is not kinked or wrinkled.

  Embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 1, a room 1 can be heated by laying a floor heating device 3 in the form of a sheet on a floor material 2 and connecting a conductor 3 a to a power source.

As a heating method, for example, far-infrared irradiation, microwave irradiation, dielectric heating and the like can be used, but the heating method is not limited to these, and any suitable temperature control can be used. A method in which the difference between the coating film's solvent divergence rate and the inside of the coating film is not preferred.

  As the PTC conductive paint used at this time, those described in US Pat. No. 5,556,576 are typically used. That is, it is a conductive paint manufactured by the following sequence of steps. (1) An aromatic solvent is put into a heated stirring vessel and heated to a temperature of 40 to 60 ° C. (2) A substrate forming material selected from a thermoplastic resin, an uncured thermosetting resin and an elastomer is added in an amount of 25 to 40% by weight of the conductive material in the subsequent step. (3) Add 25-40% by weight paraffin of the conductive powder to be added and continue stirring until all solids are dissolved. (4) Add conductive fine powder selected from graphite, carbon black, metal powder, etc. and stir until a smooth paste is formed. (5) The paste is kneaded until it becomes a substantially uniform dispersion of conductive fine powder. The PTC conductive paint obtained in this manner is used by being applied to or dipped in a fabric or fiber. Next, as the floor sheet 6, a commercially available floor heating compatible product such as the Nankai Art Floor 21 is used, and a thickness of about 3 mm is desirable, but the floor sheet 6 is not limited to this thickness. 6 mm, 9 mm, and 12 mm can be selected according to the site.

  Then, as shown in FIG. 3 in particular, laminated flat wires 7 and 7 for passing a current to the sheet heating element 5 comprising the sheet heaters 5a of the floor heating device 3, and copper wires of the sheet heaters 5a.
