  A specific embodiment 1 of the present invention will be described with reference to FIGS.

  The present embodiment is a floor heating apparatus that heats the floor member 1 by providing an appropriate heat generating portion 2 below the floor member 1.

  Specifically, the heat generating portion 2 includes a plurality of substrate materials 7 arranged in parallel on the upper surface of the joists 6, a heat conductive plate material 8 arranged in parallel on the upper surface of the substrate material 7, and a heat conductive tube material 9. It consists of

  As shown in FIGS. 1 and 2, the substrate material 7 is an appropriate wooden plate material, and an interval at which a groove 8 a of a heat conductive plate material 8 and a heat conductive tube material 9, which will be described later, can be disposed on the upper surface of the joists 6. It is laid through S. Reference numeral 11 is a big deal.

  As shown in FIGS. 1 and 2, the heat conductive plate 8 is formed by forming a copper plate into a plate shape, and is fitted at the center position of the surface to the portion located at the interval S between the substrate materials 7 described above. A concave groove 8a is formed. The concave groove 8a may be formed by manually pressing at the site, or may be formed in advance by press working at a factory or the like.

  As shown in FIGS. 1 and 2, the heat conductive tube material 9 is formed by forming an appropriate synthetic resin member (crosslinked polyethylene) into a tubular shape. In this embodiment, a fluid circulation path that circulates a heat generating fluid (hot water) by inserting a single heat conductive tube material 9 into each of the concave grooves 8a of the above-described heat conductive plate material 8 and arranging it in a meandering state. R is formed. A boiler device with a pump function (not shown) is connected to the fluid circulation path R. Therefore, after the warm water led out from the boiler device passes through the fluid circulation path R and returns to the boiler device and is warmed again. Derived.

  The fluid circulation path R is formed by a combination of a straight type heat conductive tube material and a U-shaped type heat conductive tube material connecting end portions of the straight type heat conductive tube material. May be.

  Further, a flooring material made of, for example, tatami or wood board is placed on the upper surface of the heat conductive plate material 8 as the floor member 1.

  When the heat generating part 2 having the above configuration passes hot water through the heat conductive tube 9, the heat of the heat conductive tube 9 is transferred to the heat conductive plate 8, and the heat transferred to the heat conductive plate 8. Is transmitted to the floor board 1 and the floor member 1 is heated.

  In the present embodiment, the heat insulating layer 3 is provided below the heat generating portion 2.

The heat insulating layer 3 is heat insulator 10 (glass wool) is disposed between the joists 6, as shown in FIGS. 1-4, the substrate member 7 and the heat insulating member 10 that will be placed on the upper surface of the joists 6 A predetermined interval L1 (about 10 mm) is set as the hollow layer portion 4.

In this embodiment, the height of the hollow layer portion 4 ( the distance L between the lower surface of the substrate material 7 and the upper surface of the heat insulating material 10) is set to a height of 10 mm to 15 mm. The heat insulation function will be dramatically improved.

Specifically, if the height of the hollow layer portion 4 is too low ( if the distance L between the lower surface of the substrate material 7 and the upper surface of the heat insulating material 10 is too narrow), the heat conduction is naturally promoted. It is considered that the higher the height of the hollow layer portion 4, the better.

  However, the applicant of the present invention paid attention to the relationship between the height of the hollow layer portion 4 and the heat conduction of the air and tried it. When the height of the hollow layer portion 4 was too high, The air convection phenomenon tends to occur between the lower part of the air and the air convection phenomenon contributes to the promotion of heat conduction. If the height of the hollow layer 4 is too high, the air convection is activated. It was confirmed that heat conduction was promoted.

  Therefore, when various attempts were made with respect to the height of the hollow layer portion 4, when the height of the hollow layer portion 4 was set to a height of 10 mm to 15 mm, the convection phenomenon of air hardly occurred ( It has the property of being difficult to convect due to viscosity.), It was confirmed that heat conduction can be suppressed as much as possible.

  Further, an aluminum material as the heat reflecting material 5 is disposed on the upper and lower portions of the hollow layer portion 4, that is, the lower surface of the substrate material 7 (and the heat conductive plate material 8) and the upper surface of the heat insulating material 10, respectively. . In addition, as this heat | fever reflective material 5, if the metal material with a small emissivity is used, the heat insulation effect with respect to radiation can be acquired, and it will not be restricted to an aluminum material, but if it is the structure which exhibits the characteristic of a present Example. It can be adopted as appropriate.

Therefore, the heat insulating effect is obtained by the heat insulating material 10及 beauty hollow layer portion 4, of course, heat to escape downward by the heat reflective material 5 provided on the lower surface of the substrate member 7 (upper portion of the hollow layer 4) The heat reflecting material provided on the upper surface of the heat insulating material 10 (the lower portion of the hollow layer portion 4) passes through the hollow layer portion 4 and is further reflected by the heat reflecting material 5. 5 is reflected upward, and an excellent heat insulating effect is exhibited (see FIG. 5).
