Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating system for heating under the floor by disposing a double tube structure under the floor and inserting a heating element (heating wire) in the inner tube. In the above, the present invention relates to a double pipe structure member and a connecting member used in this floor heating system.

[0002]

2. Description of the Related Art Conventionally, a floor heating system has been constructed by circulating a heated heat medium liquid in an elongated seamless pipe (seamless pipe) arranged under the floor.
The heat released from the heat carrier liquid warms the floor surface from below the floor, or the heat generated from the heating wire is transmitted to the floor surface by energizing a thin heating wire arranged under the floor. There was something I did. Then, in the one that circulates the heat transfer medium liquid, first, the seamless pipe made of a material having good thermal conductivity and the buried panel for arranging this seamless pipe under the floor, A circulation path is provided, and in order to heat the heat medium liquid in this seamless pipe, a boiler is provided outside the circulation path, and a pump for forcibly circulating the heat medium liquid is provided in the middle of the circulation path. It was provided. On the other hand, in the case of the heating wire, the floor surface had to be made of concrete in order to fix the arranged position.

[0003]

However, in the above-mentioned floor heating system in which the heat medium liquid is circulated, the temperature gradually increases while the heated heat medium liquid circulates in the seamless pipe. Therefore, in the first half of the circulation path (position near the boiler), the floor of the part through which the heat transfer fluid passes becomes hot, but in the second half of the circulation path (position far from the boiler), the heat transfer fluid passes. The temperature of the part of the floor did not rise, and the entire floor surface could not be heated uniformly. In addition, since a pump is used to forcibly circulate the heat medium liquid in the seamless pipe, a large pump is required when the circulation path is long or the heat medium liquid is a viscous substance. At the same time, the load on a small pump increases, and maintenance costs a lot. Further, although a boiler is used to heat the heating medium liquid, heating by such a boiler generally heats the entire tank in which the heating medium liquid to be heated is stored. Since the heating including the heat medium liquid that does not circulate occurs, a large amount of heat energy is lost, and heat is also released in the middle of the circulation path, which also loses heat energy, resulting in high running costs. It was a thing. Moreover, as a seamless pipe to be installed under the floor, a copper pipe is generally used, but it is necessary to manually bend or bend the pipe to form a wavy circulation path. The installation work required skillful techniques and required a long time, and the floor heating work was prolonged, so the construction cost was not low.

On the other hand, in the floor heating system using the heating wire, it is expected that the temperature of the heating wire itself does not rise easily, but the floor surface may not be heated to a desired temperature. It was difficult to heat up at the temperature. Also, if you stick to only the rise in temperature and increase the voltage or current of the heating wire, the heating wire will become hot and it will be possible to radiate heat to a sufficient extent for heating, but on the other hand, it requires a lot of power consumption. The running cost was very high. Further, since the heating wire is fixed to the installed position with concrete, it can be used only when the floor surface is finished with concrete, and cannot be adopted in a general house.

Therefore, the applicant has filed a Japanese Patent Application No. 7-12144.
No. 9 filed a floor heating system using a double tube structure. In the invention according to this application, the double pipe structure is arranged in parallel, and both ends of the double pipe structure are connected to the parent pipe to connect the internal space to form a double pipe structure. The heating element is inserted inside the inner tube. Furthermore, the applicant applied for Japanese Patent Application No. 8-28050. The invention according to this application is configured such that the outer pipe of the double pipe structure described above has a substantially corrugated shape, and the connection between the outer pipe and the inner pipe of the double structure and the connecting member is screwed. It was made possible to wear it, and it was possible to prevent air from remaining in the outer tube and to simplify the construction.

[0006] However, although the above-mentioned technique makes the construction easier than the previous floor heating, it cannot be denied that the amount of work at the construction site is still large, and construction in a short period such as extension and renovation is necessary. In some cases, it could not be dealt with.

In view of the above points, it is an object of the present invention to provide a floor heating structure which can reduce the amount of work at a construction site and can be constructed in a short period of time.

In this case, the insertion pipe 12 of the double pipe structure member 10 and the connection inner pipe 22 of the connection member 20 are not connected, but this insertion pipe 1
2 (or the heat carrier liquid) inside the inner pipe 22 and the connecting inner pipe 22.
Since it does not flow in, it does not have to be connected, and if it is intentionally connected, it can be connected by the L-shaped pipe 26 and the pipe joint 27.

Next, a second embodiment of the connecting member of the present invention will be described.

As shown in FIG. 7, the connecting member 30 of this embodiment is a branch pipe 13 (FIG. 3) of the double pipe structure member 10.

Connection is easy. Further, the vicinity of both ends 33, 34 of the connecting inner pipe 32 is similarly connected, and the both ends 33, 34 face the open ends 16, 17 (FIG. 3) of the insertion pipe 12 of the double pipe structure member 10. You can do it. Here, the connecting inner tube 32 means that the connecting inner tube 32 is not inserted through the inside of the connecting outer tube 21, but is provided so as to be in contact with the inside of the bend of the connecting outer tube 31. .

Next, a second embodiment of the double pipe structure member will be described.

As shown in FIGS. 9 and 10, in the double pipe structure member 110 of this embodiment, the double pipe structure member 10 (FIG. 3) shown in the first embodiment is mounted on the heat dissipation plate 140 having a predetermined area. The heat-radiating plate 140 is welded, and a synthetic resin 150 for heat insulation is sprayed on the lower surface of the heat-radiating plate 140 and then solidified. The heat radiating plate 140 is a thin-walled zinc-plated plate, and the heat of the heating wire inserted into the insertion tube 112 of the double-tube structural member 110 is transmitted to the short tube 111, and the heat radiating plate 1
It is uniformly transmitted to the floor surface via 40. Further, two double pipe structural members 10 (FIG. 3) shown in the first embodiment are welded to the heat dissipation plate 140, and the branch pipes 113a and 113b are inserted into the insertion pipe 112a as shown in FIG. , 112b, and when both branch pipes 113a, 113b are inserted through the insertion pipe 11 as shown in FIG.
In some cases, they may be arranged closer to the terminals 2a and 112b, and only one of them may be used, but they can be used as needed.

Short pipes 111a, 111b and branch pipes 113a, which constitute the double pipe structure member 110,
113b is a synthetic resin 1 for heat insulation as shown in FIG.
By 50, almost the whole is surrounded, and it is sufficiently adhered to the lower surface of the heat dissipation plate 140 to improve the adhesion between the heat dissipation plate 140 and the short tubes 111a and 111b. Also,
As shown in FIG. 11A, the heat dissipation plate 140 is bent in a U-shaped cross section near both side edges, and the bent end portion 14 is bent.
1, 142 and the flat surface portion of the heat dissipation plate 140 can have a constant space. by this,
Since the heat dissipation plate 140 can be provided at a predetermined height, the flat surface portion of the heat dissipation plate 140 can be brought into close contact with the back surface of the finishing material such as a flooring, and the heat transfer rate to the floor surface can be improved. Further, as shown in FIG. 11B, since the lower part of the heat dissipation plate 140 is hollow, an air layer can be formed in this portion, so that the heat insulating effect is also improved. In addition, the branch pipe 113 is replaced by the short pipe 11.
If the branch pipe 113 has the same diameter as that of 1, the branch pipe 113 can also be easily brought into close contact with the lower surface of the heat dissipation plate 140.

Further, in the connecting members 20 and 30 as in the structure of the double pipe structure member 110, the synthetic resin is sprayed while the connecting outer pipes 21 and 31 are welded to the zinc-plated thin radiator plate. It is also possible to form it integrally with the heat dissipation plate. In this case, most of the structure is the same as that of the double pipe structure member 110, and therefore the description thereof is omitted.

In the floor heating system using the second embodiment of the double pipe structure member 110, as shown in FIG. 12, the heat dissipation plates 140a ... 140b of the double pipe structure members 110a. In a predetermined direction (short tube 11
1a ... 111b are arranged so that they can be continuous in the axial direction), and the insertion tubes 112a ... 112b facing each other, or
By connecting the opposed branch pipes 113a ... 11b to each other, a long double pipe structure can be provided. Further, the double pipe structure member 110a ... 1 described above.

110d is also arranged and similarly a long double tube structure can be provided. And the arranged double pipe structure member 11
At both ends of 0 (upper and lower ends in the drawing), which correspond to substantially wavy curved portions, the first connecting member 20 or the second connecting member 30 is used. In FIG. 12, the second connecting member 30 is used on one side (upper side in the drawing) and the first connecting member 20 is used on the other side (lower side in the drawing). Further, at this time, the double pipe structure members 11 arranged in parallel
It is desirable that the short tubes 111 of 0 are arranged at equal intervals, and therefore, both ends 2 of the connecting outer tube 21 of the connecting member 20.
5, 26 and both ends 3 of the connecting outer tube 31 of the connecting member 30
The widths of the pipes 5, 36 are adjusted to the width of the branch pipe 113 branched from the short pipe 111.

Needless to say, various embodiments can be taken without departing from the spirit of the present invention. For example, in the second embodiment of the double pipe structure member, the synthetic resin is sprayed for heat insulation, but instead of the synthetic resin, a foamed plastic is formed into a panel shape, and the short pipe 111 and the short pipe 111 are formed on the surface of the foamed plastic. Branch pipe 113
May be provided with a groove portion capable of being fitted, and in this case, the short pipe 111 is not welded to the lower surface of the heat dissipation plate 140, and the short pipe 111 and the branch pipe 113 are fitted into the groove portion provided in the foam plastic panel. The combined product may be inserted into a space formed by the heat dissipation plate 140 and the bent end portions 141, 142 near both side edges.

Further, the embodiment of the connecting member shown above is a substantially U-shaped connecting member in both the first and second embodiments, and by using this connecting member, the double members arranged in parallel are provided. Although the pipe structure member can be connected in a substantially wave shape, as shown in FIG.
It is also possible to make arc. In this case, the branch pipe 13 (FIG. 3) of the double pipe structure member 10 to be connected is the connecting member 2
30 can be connected to the connection outer pipe 231 and the insertion pipe 12 (FIG. 3) can also be connected to the connection inner pipe 232, and the two double pipe structure members 10 connected at both ends of the connection member 230 can be connected at different angles. It becomes a state having.
By providing the connecting outer pipe 231 so as to form a quarter of the circumference as shown in the figure, the double pipe structural member 210 can be connected at 90 ° as shown in FIG. The double pipe structure member 210 can be arranged differently from the corrugated shape. Therefore, by combining this connecting member 230 and the above-mentioned substantially U-shaped connecting members 10 and 20, the double pipe structure member 21 can be formed in accordance with various shapes.
Since 0 can be provided, floor heating or local floor heating according to the shape and size of the room can be enabled.

As described above, according to the present invention, the double pipe structure of the floor heating system has a double pipe structure including a short pipe and an insertion pipe which are divided into several parts. In the state of being inserted into the short tube, since the vicinity of both ends of the insertion tube is tightly fixed, water or heat medium liquid does not flow from the short tube into the insertion tube, and the inside of the short tube The supplied water or heat medium liquid is connected to the next short pipe through the branch pipe branched from the short pipe, and the water or heat medium liquid can be supplied at one place. Further, since no pressure is applied to the water or the heat medium liquid supplied into the short pipe, a strong sealing member is not necessary for connecting the branch pipes to each other, and a simple rubber cylinder is used. Fittings are sufficient. Therefore, at the construction site, while arranging the double pipe structure member and the connecting member, the branch pipe and the branch pipe at the opposite position, or
Since it is possible to arrange each pipe having a double structure by simply connecting the insertion pipe and the insertion pipe at the opposite position, it is possible to reduce the type and amount of work, and to carry out the construction in a short period of time. Is realized.
