Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a heat generating panel for floor heating that provides an excellent feel to the soles of the feet.

(Prior art) Conventionally, this type of heating panel for floor heating has been constructed by integrating a heating element between a thin upper plate and a thick lower plate (for example, see Japanese Utility Model Application Publication No. 58-74013). ), and the heating element is a heating wire,
It is known that this is housed in a groove provided in the lower plate, a metal foil heat equalizing plate made of aluminum foil or the like is further laminated on the heating wire, and a thin upper plate is laminated and integrated on top of this. There is.

The top surface of these panels is made of wood, so
Of course, if a carpet is laid on top of this,
Even when the upper surface of the panel is used directly as the floor surface, it has the advantage of superior foot feel compared to other panels such as those made of metal, and the latter has the advantage of being thinner overall.

However, since the upper and lower panels of the two panels have different thicknesses, their actual volumes, that is, their heat capacities, are different, so if they are installed upside down, the thermal efficiency will deteriorate, and the panel installation will be difficult. In this case, care must be taken to ensure that the front and back sides are not reversed, which is a troublesome work.Moreover, the upper and lower panels of this type of panel are very similar in appearance, and it is difficult to lay the panel. This method has disadvantages such as complicated work.

(Purpose of the invention) In view of the above-mentioned circumstances, the present invention provides a heat-generating panel for floor heating which not only has an excellent feel under the feet but also has a thinner overall thickness and can be installed upside down. The purpose is to

(Structure of the invention) In order to achieve the above object, the invention is structured as follows.

That is, in the present invention, a groove having a predetermined circuit shape is formed on the surface of the lower plate, a heating wire is housed in the groove, a metal foil is laminated on the groove, and the thickness of the lower plate is laminated on the metal foil. In a heat generating panel for floor heating formed by laminating thinner upper plates, the volume occupied by the groove is substantially the same as the volume difference between the lower plate and the upper plate.

As the bottom plate and the top plate, the same rigid plate materials such as hardboard, particle board, plywood, etc. can be used, and as the metal foil, aluminum foil, a material covered with plastic film, etc. can be arbitrarily used. This metal foil acts as a heat equalizing plate.

(Example) Next, an example of the present invention will be described based on FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a bottom plate made of plywood. A groove 3 is formed in the surface of the bottom plate 1 in a predetermined circuit shape, for example, a meandering shape, and an insulated heating wire 4 is formed in the groove 3.
It is arranged to store.

A copper foil 5 is adhesively laminated on the heating wire 4 so as to be in contact with the heating wire 4 and to cover substantially the entire surface of the bottom plate 1.

On top of the copper foil 5, an upper plate 6 made of substantially the same material as the lower plate 1 is adhesively laminated.

The thickness of the upper plate 6 is made thinner than that of the lower plate 1, and the difference is such that the substantial difference in volume between the lower plate 1 and the upper plate 6 is approximately the same as the volume occupied by the groove 3. .

Further, in this embodiment, as shown in FIG. 2, a temperature control circuit including a temperature fuse 7 and a thermostat 8 are inserted and connected in series in the circuit of the heating wire 4, and these are housed. A groove is provided parallel to the groove 3. Therefore, the top plate 6
The thickness, that is, its volume, is calculated by subtracting the volume occupied by both the groove 3 and the groove housing the temperature control circuit.

As the lower surface plate and the upper surface plate, in addition to plywood, a board material of the same quality having wood-based rigidity such as hardboard or particle board may be used. Also, as a metal foil,
In addition to copper foil, aluminum foil or the like may be used, and any material such as one coated with plastic film may also be used.

The metal foil, for example, the copper foil 5, is divided into a plurality of pieces as shown in FIG. They may be adhesively laminated to the bottom plate 1 so that they are in contact with each other. In this way, a small metal foil can be used instead of a large one, and its handling becomes easy.

Further, the surfaces of the lower plate 1 and the upper plate 6 can be appropriately covered so that they directly constitute the floor surface.

Furthermore, if the thickness of the upper and lower plates 1 and 6 is too thick, the thermal efficiency will deteriorate when used upside down, so it is usually desirable to select a thickness in the range of 2 m/m to 7 m/m.

The heat-generating panel for floor heating of the present invention constructed in this way can be constructed by laying it on a base directly or through a heat insulating layer, or by laying a carpet or the like on top of it to form a floor. The heat source generates heat to heat the room.

(Effects of the invention) However, according to the heat generating panel for floor heating of the present invention, the bottom plate and the top plate are made of wood-based rigid boards, so there is no need to place other flooring materials between the joists. Can be used as flooring. It also has the following effects.

That is, the heat-generating panel for floor heating of the present invention has a configuration in which heating wires are interposed between the bottom plate and the top plate, and the surface thereof is made of wood material, so it has an excellent feel on the soles of the feet.

Furthermore, since the heating wires are housed and arranged in the grooves formed in the bottom plate, no arrangement jig or the like is required, which not only simplifies the arrangement work but also allows the overall thickness to be reduced.

Furthermore, since metal foil is placed on one side of the heating wire, there is less risk of local overheating.

Moreover, the thickness of the top plate is made thinner than the bottom plate with grooves formed thereon, and the volume occupied by the grooves in the bottom plate is made approximately equal to the volume difference between the bottom plate and the top plate.
The heat capacities of the upper and lower plates can be approximately the same, so even if they are installed with the front and back sides reversed, there will be little difference in thermal efficiency, making the installation work easier as there is no need to pay attention to both sides when laying. .
