Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a floor heating system in which a carpet-shaped heater unit is laid on the floor of a room and heats the room by heating from the floor.

(Prior Art) As shown in Fig. 10, a conventional floor heating system consists of laying a planar heater unit 1 of 1 to 3 tatami mats in size on the floor at the required location, and placing felt 16 on the floor around it. Generally, carpets 17 of the same size as the floor area are laid on top of them.

(Problems to be solved by the invention) The above-mentioned floor heating system has poor workability because the carpet 17 cannot be brought in and laid without relocating the furniture, and the heater unit 1 breaks down and requires maintenance and inspection. At that time, the carpet 17 had to be removed, which was troublesome.

On the other hand, some systems have adopted a method in which multiple 1-tatami-sized heating elements are lined up and wrapped in a cover, and the electric wires for each heating element are collectively connected and laid on the floor, but this method allows the freedom to install the heater on-site. This also has various practical inconveniences because the heater cannot be placed in the same position as the heater, and even if a part of the heater breaks down, the entire heater must be inspected and replaced.

To address these problems, the present invention forms the heater unit into a half-tatami or one-tatami unit, and also includes a half-tatami or one-tatami tile-shaped carpet as auxiliary members, and a surrounding edge material for accommodating electric wires. By installing a tile, the work can be easily done in the same way as laying tiles, and the wiring work is easy and the wiring is not exposed on the floor at all, preserving the appearance.
This was done in an attempt to provide a floor heating system that can be easily relocated and inspected, and the purpose is to contribute to the simplification and generalization of floor heating systems.

(Means for Solving the Problems) As is clear from the drawings related to the embodiment, the present invention has a heat-sensitive wire sensor 5 and an electric heater 6 pasted on the front side of a heat-resistant backing material 4, and a carpet 7 on the front side. A heater unit 1 is formed by pasting together a carpet 7 to a size of approximately half a tatami mat or one tatami mat, and a carpet 7 is pasted to the front side of a backing material 8 to form the heater unit 1.
A tile-shaped carpet 2 having the same thickness as that of the carpet 2 and having at least one groove 9 across the back side of the backing material 8 for inserting electric wires so as to have a size of about half a tatami mat or about 1 tatami mat, and a tile-like carpet 2 for accommodating electric wires. The basic material is a trough-like main body 10 and a top cover 11, the same height as the thickness of the heater unit 1, and a surrounding edge material 3 with a cutout 15 for inserting and removing electric wires. One or more of the units 1 are laid, one or more of the tile-like carpets 2 are laid around the surrounding floor area, and the surrounding edge material 3 is placed on the floor corner area around the tile-like carpet 2, and the surrounding edge material 3 is placed on the wall. controller and electric heater 6 of heater unit 1
The electric wire 12 connecting the heat-sensitive wire sensor 5 and the heat-sensitive wire sensor 5 is inserted into the groove 9 of the tile-like carpet 2 and around the surrounding edge material 3.
The underfloor heating system is constructed by disposing it within the gutter-like main body 10 of.

(Function) Since the heater unit 1 and the tile-like carpet 2 are formed in units of approximately half a tatami mat or approximately one tatami mat, they can be laid from anywhere in the room, and the furniture only needs to be slightly relocated. Furthermore, the wires can be routed in any direction by using the grooves 9 of the tile-like carpet 2 and the surrounding edge material 3.

Furthermore, the heater unit 1 can be freely arranged or relocated in accordance with rearrangement of furniture or rearrangement of the room.

(Example) In FIGS. 1 to 6, 1 is a heater unit, 2 is a tile-like carpet, and 3 is a surrounding edge material. Heat-sensitive wire sensors 5 and electric heaters 6 arranged in a meandering manner on the front side, for example, a surface heating element made of a fluororesin film containing powdered carbon, are pasted together, and a carpet 7 is further pasted on the front side, so that the thickness is, for example, 20 mm. Form it into the size of half a tatami mat (900 x 900 mm) or one tatami mat (900 x 1800 mm).

Although the wire connection terminals of the heat-sensitive wire sensor 5 and the electric heater 6 are not shown, they are provided on the side edges of the back surface material 4.

The tile-shaped carpet 2 is formed by laminating a carpet 7 on the front side of a backing material 8 made of the same material as the insulating backing material 4, and having the same thickness as the heater unit 1 and the size of half a tatami mat or one tatami mat. Further, on the back surface of the back material 8, at least one groove 9 for inserting electric wires is formed, for example, four grooves intersect as shown in FIG.
In addition, they are individually provided parallel to each side in a transverse manner.

Note that the groove 9 is provided at a location that can correspond to the electric wire connection terminal provided on the heater unit 1, and a filler 13 is usually inserted in this groove 9 so that it can be removed only in the area where the electric wire is passed. Furthermore, the dimensions can be adjusted by cutting at the groove 9 to match the floor plan of the room.

The surrounding edge material 3 is made of hard synthetic resin and is formed of a square gutter-shaped main body 10 and an upper cover 11 that elastically engages with the opening of the main body 10 (fifth
(See Figures A and B), it is a long piece with the minimum width sufficient to accommodate the required number of electric wires 12 at the same height as the heater unit 1, and when laying it, cut it to an appropriate length with a hacksaw blade. The gutter-like main body 10 has cutouts 1 at necessary locations for inserting and removing electric wires 12.
5 (see Figure 6).

When assembling a floor heating system using these members 1, 2, and 3, as illustrated in FIGS. 7 to 9, a plurality of heater units 1 are placed side by side in the center of the floor of the room, A necessary number of tile-like carpets 2 are laid around the floor, and a surrounding edge material 3 cut to a predetermined size is further arranged at the corner part of the floor.

In this way, the heater unit 1, the tile-like carpet 2, and the surrounding edge material 3 are arranged in close contact with each other and are arranged side by side across the entire width of the room, so that the heater unit 1 is securely fixed in a predetermined location, and there are no steps on the surface. .

The electric wire 12 connected to the electric wire connection terminal of the heater unit 1 is inserted into the groove 9 of the adjacent tile-like carpet 2, and then inserted into the surrounding edge material 3 through the notch 15, so that the wall is not raised. The wiring work is completed by connecting it to the attached controller 14.

In this way, the floor heating system can be installed in a location that suits the size and interior design of the room.

(Effects of the invention) This invention is based on the basic unit of room configuration, which is half a tatami mat or one
Since the heater unit 1 and carpet tiles 2, which are sized to match the tatami mats and have the same thickness, are placed on the floor, the laying work can be done from anywhere, and there is no need for a large space. It is also easy to transport.

In addition, each heater unit 1 is surrounded by a tile-like carpet with grooves on its back side, and the wiring is guided through the grooves, so that they can be freely arranged and relocated, making it easy to install heaters that match the layout of the room.

The present invention accommodates the electric wires in the tile-like carpet 2 and the surrounding edge material 3, making inspection and servicing easy, and since no wiring is exposed on the floor, it is excellent in terms of both aesthetics and safety.

Furthermore, since the heater unit 1 has an integral heat insulating material on the back side, there is no need to install a heat insulating material on site, and there are advantages of high heat retention performance and low running costs.
