Abstract

PURPOSE:To obtain a floor heater having excellent heat transfer properties which can withstand repeated heating and colding for a long time, inhibit the generation of differential temperature between a floor surface and the top face of a joist, even when it is installed by way of a beam (floor joist) which supports the floor surface, and moreover which can be installed even if there is a difference in level between the floor surface and a floor heater. CONSTITUTION:A lower part heat equalizing board 3 made of aluminum and copper or the like, is laminated on the top of an insulation material, such as felt where a tubing heater 4 or an electric heating medium is laid out thereon. Furthermore, an upper part heat equalizing board 6, which is provided flexible and thermal conducting properties, and a surface member 5, are alternately laminated. The upper part heat equalizing heating board 6 on one side edge is adapted to extend in one piece so that a plurality of holes or meshes of a net through which a bonding agent is penetrated, may be formed on the extended portion 8 in the longitudinal direction. The floor heater is nailed or adhered to the floor 11 and the surface material 5 and connected with its adjacent floor heater, allowing the extended portion 8 on the edge to rest on the joist.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heater for heating from the floor surface and a method for installing the same.

0002

2. Description of the Related Art Conventional floor heaters of this type and their installation methods generally have a structure as shown in Japanese Patent Application Laid-Open No. 63-58037. The configuration will be described below with reference to FIG.

As shown in the figure, the floor heater 12 has a heating element 14 disposed on an insulating sheet 13, and an insulating sheet 15 and an upper heat equalizing plate 16 successively laminated thereon. Then, a thermally conductive tape 17 having an adhesive layer on one longitudinal side of the upper heat equalizing plate 16 and having holes arranged in the longitudinal direction is extended outward from one side edge of the upper heat equalizing plate 16. Paste it like 5. Then, adhesive is poured onto the underfloor beam (hereinafter referred to as joist) through a hole 18 provided in the overhanging portion of the tape 17 to fix the floor heater and the flooring material 11.

[Problems to be Solved by the Invention] Such a conventional floor heater and its installation method are characterized by pasting the thermally conductive tape 17 on the heat equalizing plate 16. Foreign matter such as adhesive is present between the tapes 17, which not only deteriorates thermal conductivity, but also causes the thermally conductive tape 17 to peel off due to deterioration of the adhesive due to long-term cooling and heating cycles such as seasonal and day/night temperature changes. There was also the risk of losing heat. In addition, adjacent floor heaters were pasted together using thermally conductive tape 17, and the joists 10 and floor 11 were also fixed using adhesive or nails using thermally conductive tape 17, making the construction process complicated. Ta.

[0005] The present invention solves the above problems, and improves heat conductivity by integrating a heat soaking plate and a thermally conductive tape, and prevents deterioration of heat conductivity due to long-term cooling and heating cycles such as temperature changes. The purpose is to simplify construction.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the floor heater of the present invention includes, in order from the bottom, a heat insulating material, a lower heat equalizing plate laminated on the heat insulating material, and a lower heat equalizing plate laminated on the heat insulating material. The heating element is further laminated with an upper heat equalizing plate made of a flexible and thermally conductive material and a surface material, one side edge of the upper heat equalizing plate is integrally extended, and the extended portion is A passage is provided through which the adhesive can permeate from the surface.

[0007]

[Function] With the above-described structure, the present invention has one side edge of the upper heat-uniforming plate made of a flexible and heat-conductive material that is integrally extended, improving thermal conductivity and allowing the joists to be positioned There is no drop in temperature on the floor either.

[0008] Furthermore, the floor can be fixed by allowing the adhesive to permeate onto the joists from the surface of the extension provided on the heat equalizing plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to the drawings. Figure 1~
FIG. 3 is a perspective view showing one embodiment of the present invention.
is a floor heater, which includes, in order from the bottom, a heat insulating material 2 such as felt, a lower heat equalizing plate 3 made of aluminum, copper, etc. laminated by pasting on the heat insulating material 2, and a heat equalizing plate 3 disposed on the heat equalizing plate 3. A tubing heater 4 made of an electric heating element is provided, an upper heat equalizing plate 6 having flexibility and good thermal conductivity, and a surface material 5 laminated on the upper heat equalizing plate. Then, one side edge of the upper heat equalizing plate 6 is integrally extended, and the extended portion is provided with a plurality of holes 7 that constitute passages through which the adhesive can permeate from the surface in the longitudinal direction, thereby forming an extended portion 8 of the upper heat equalizing plate. are doing.

In order to install the floor heater 1 of the present invention constructed as described above under the floor indoors, as shown in FIGS.
The insulation material 9 is sequentially laid between the 10 sections. Then, after connecting the adjacent floor heaters 1 via the joists 10 by placing the extension 8 of the upper heating plate 6 having a plurality of holes 7 in the longitudinal direction on the joists 10, Apply adhesive onto the joists 10 through the plurality of holes 7 of 8 and attach the joists 10.
The extension part 8 of the upper heat soaking plate and the surface material 5 of the floor heater 1 adjacent to the floor 11 are bonded and installed under the floor indoors. In addition,
The floor 11 can also be nailed to the joists 10 if desired.

In the above embodiment, a plurality of holes 7 are provided in the extension 8 of the upper heat soaking plate, but the same effect as in the above embodiment can also be obtained by using holes 7 in the form of notches or meshes as shown in FIGS. 2 and 3. It is something to play.

0012

[Effects of the Invention] As is clear from the above embodiments, the following effects can be obtained according to the floor heater and the installation method thereof of the present invention.

By extending one side edge of the flexible upper heat equalizing plate integrally, even if there is a slight level difference between the floor heater and the upper surface of the joist, one side of the upper heat equalizing plate can be easily extended. The floor heater can be connected by adhesively placing the extension of the edge on the joist through the joist.

[0014] Since one side edge of the upper heat equalizing plate made of a flexible and thermally conductive material is integrally extended, the heat from the heating element passes through the upper heat equalizing plate and is distributed uniformly over the entire floor surface. The entire room can be heated uniformly from the floor surface without causing a temperature difference between the floor surface where the floor joists are located and the floor surface where the floor heater is installed.

[0015] One side edge of the upper heat equalizing plate is integrally extended and there is no need for a thermally conductive tape as in the conventional example, so there is no possibility that foreign substances such as adhesive may get between the heat equalizing plate and the heat conductive tape. Since there is no intervening material, the heat conductivity is good, and no deterioration in thermal conductivity occurs due to long-term cooling/heating cycles such as temperature changes.

[0016] Since the extension portion of the upper heat equalizing plate is integrated with the floor heater, the floor heaters can be installed firmly and easily through the joists.
