Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a floor heating rug and a floor heating structure.

[0002]

[Prior art]

 Conventionally, the most common method of floor heating is to provide a pipe or the like on the back side of the floor and warm the floor by supplying hot water or the like.

[0003]

[Problems to be solved by the device]

 However, in the above method, when floor heating is applied to a rug material such as a tatami mat having heat insulation, there is a contradiction that the heat insulation effect of the rug material impairs the heating effect.

[0004]

[Means for Solving the Problems]

 The floor heating rug material of the present invention for solving the above problems has a large number of heat radiation holes 34 formed on the front and back sides in a plate-shaped core material 33 having a constant thickness, which is rich in heat insulation and heat retention. However, the surface side is covered with a surface layer material. Further, in the floor heating structure of the present invention, the thin heat dissipation plate 37 is supported on the floor structure member 42, and the heating pipe 28 is piped in proximity to or in contact with the heat dissipation plate 37. The rug material according to claim 1 is laid.

[0005]

[Action]

 The rug material heats the core material 33 by heating the core material 33 by applying heat from the lower part and heats the core material 33 there, and also radiates heat to the surface material on the upper surface to warm the surface side. The heat retained in the core material 33 also warms the surface layer material. Further, the heat radiating plate 37 is heated by the heat medium flowing through the pipe 28, and the heat is transferred to the whole by heat conduction.

【Example】

 The drawing shows the outline of the connection of the main piping 2 in each building floor 1, the piping diagram of the floor heating system 3 and the detailed structure of the rug material in the floor heating system 3. Fig. 1 shows the fan coil and floor heating combined air conditioning system. FIG. In this embodiment, a supply branch pipe 8 and a return branch pipe 9 extending from a main pipe 2 including a supply pipe 6 and a return pipe 7 are provided as a fan coil unit 11 and a specific branch pipe 1 in a partition part 1 of each building floor or room. It is connected to the floor heating device 3 in the compartment 1. A heat source device such as a cold / hot water generator 12, a cooling tower 13 and an expansion tank 14 are installed on the rooftop and the main pipe 2 is connected to each of the above devices. A heat exchange section 16 is formed by the cold / hot water generator 12, the cooling tower 13, and the like. Each part will be described in detail below with reference to the drawings.

The main pipe 2 is composed of a supply pipe 6 and a return pipe 7, and a heat medium such as cold / hot water flows in the supply pipe 6 and the return pipe 7 depending on the case. The supply pipe 6 is connected to a cold / hot water generator 12 installed on the top floor, and further connected to a cooling tower 13. An expansion tank 14 is connected to the base end of the return pipe 7, and the expansion tank 14 adjusts the internal pressure to escape and improves the flow of the heat medium. Further, the return pipe 7 is branched at the top floor, and the return branch pipe 9 of the return pipe 7 is connected to the cold / hot water generator 12 via the pump 17 for cold / hot water, and the cold / hot water generation is further performed. The heat exchanger 16 is connected to the cooling tower 13 from the machine 12 via the pump 18 for cooling water.

A medium such as water heated or cooled by the cold / hot water generator 12 is supplied to the fan coil unit 11 and the floor heating device 3 through the supply pipe 6 and the supply branch pipe 8. The supplied medium is sent into the above device, passes through the pipe provided inside the device, and is then returned to the return pipe 7 through the return branch pipe 9. The pressure of the returned medium is adjusted by the expansion tank 14, is pulled up by the cold / hot water pump 17, and is fed into the cold / hot water generator 12. Further, after being sent to the inside of the cooling tower 13 by the cooling pump 18 to be cooled, it is supplied again to the cold / hot water generator 12, and is supplied to each device of each building floor 1 by the supply pipe 6.

A piping structure in the floor heating system 3 will be described with reference to FIG. The supply branch pipe 8 and the return branch pipe 9 connected to the floor heating device 3 are connected to a plurality of supply pipes 22 and return pipes 23 via a central piping part 21, and a Japanese-style room 26 and a Western-style room 27 etc. via a corridor 24. Plumbed to each room. At this time, the supply pipe 22 and the return pipe 23 are arranged close to each other and are arranged so as to form a counter convection in which the supply flow and the return flow are alternately formed. The pipe 28 is a highly cross-linked polyethylene resin hot water pipe made of high molecular weight polyethylene having a network structure in which the middle parts of the molecules are bonded to each other instead of polyethylene composed of a chain polymer, and a medium such as hot water is supplied. The supply pipe 22 and the return pipe 23 for returning the hot water are seamless long pipes (up to 300 m). In this embodiment, as a floor heating method, a hot water floor heating method is used in which piping is provided under the floor by the pipe 28, and heating is performed by supplying a medium such as hot water to the pipe 28.

Next, the piping structure of the supply pipe 22 and the return pipe 23 in the Japanese-style room 26, the Western-style room 27, etc. will be described in detail. In the relatively small Japanese-style room 26, the supply pipes 22 and the return pipes 23 are alternately piped so as not to contact and communicate with each other. By alternately supplying the supply pipes 22 and the return pipes 23, uneven heating due to places is eliminated, and the temperature of the entire floor surface is kept uniform. The details of the piping structure of this Japanese-style room will be described with reference to FIGS. 4 and 6. On the other hand, in the Western-style room 27, etc., it is connected to the return pipe 23 as a turning point of the supply pipe 22 so as not to intersect with each other but keeping them parallel and close to each other. The effect that the entire floor surface is heated evenly is obtained as in the case of the piping. Further, as shown in FIG. 2, when the western room 27 and the like are wide, a plurality of spirals are formed and the supply pipe 22 and the return pipe 23 are arranged.

FIG. 3 is an enlarged view of the centralized piping section 21. The centralized piping section 21 branches from the main piping 2 connected to the heat exchange section 16 in FIG. The branch pipe 9 is configured to be connected to the forward header 31 and the return header 32. The supply branch pipe 8 is connected to the forward header 31, a plurality of supply pipes 22 are branched from the forward header 31, and the supply pipe 22 supplies a medium such as hot water to each place such as the Japanese-style room 26.

Further, the same number of return pipes 23 as the supply pipes 22 are connected to the return header 32, and the hot water supplied to each place such as the Japanese-style room 26 is returned by the return pipe 23 via the return header 32. It flows out to the branch pipe 9. The hot water further flows into the heat exchange section 16 through the return pipe 7 to be warmed, and then is sent to the supply pipe 6 again and is supplied to the inside of the floor heating device 3. After being supplied, the above operation is repeated.

Next, the floor heating device 3 in the Japanese-style room 26 will be described with reference to FIG. FIG. 4 is a cross-sectional view of the floor heating device 3 in the Japanese-style room 26. In this example, Japanese tatami mat 5 was used as the rug material. Instead of the straw that is generally used for the floor of the Japanese tatami mat 5, a board obtained by press-molding crushed wood material is used as the core material 33, and as shown in FIG. The heat radiation holes 34 are formed at a pitch, and the front and back surfaces are covered with a thin protective sheet 36 adhered thereto. Further, a pipe 28 is arranged on the back surface of the Japanese tatami mat 5, and the pipe 28 is supported by a heat radiating plate 37 made of, for example, thin aluminum having a thickness of about 0.7 mm. , A large pull 39, and a joist 41, and is mounted and supported together with the tatami mat 5 and the pipe 28 on the upper surface of the floor structure member 42. The pipe 28 is arranged so that the supply pipe and the return pipe are alternately located like the pipe of the Japanese-style room 26 in FIG.

The large pull 39 and the joists 41 are installed in a lattice pattern, and the joists 41 support the heat dissipation plate 37, so that the bottom is hollow. A space 44 is formed by the pulling 39, joists 41, the heat dissipation plate 37, and the heat insulating material 43 by closing the lower surface of the cavity with the heat insulating material 43 made of hard styrene foam. During operation of the floor heating device 3, not only heat does not leak to the outside, but also the heat of the radiator plate 37 is held by warming the space 44, and the upper portion of the radiator plate 37 is connected to the tatami mat 5. Improves heat transfer.

As shown in FIG. 6, the core material 33 of the Japanese tatami mat 5 is provided with a heat dissipation hole 34, which is composed of a lower hole 46 and an upper hole 47. 46 is larger than the upper hole 47. Both the front surface and the back surface of the core material 33 are covered and protected by a protective sheet 36, and a Japanese tatami mat 5 made of strawberries is further attached to the surface through the protective sheet 36, and the back surface also serves as a floorboard. A heat sink 37 is attached so as to support the pipe 28. As the protective sheet 36, for example, a vinyl mesh coated with a resin is used, and it serves to protect both sides and prevent moisture.

The heat dissipation plate 37 is provided with a pipe supporting portion 49 having an arcuate groove for supporting the pipe 28, and the inner surface of the pipe supporting portion 49 is in contact with the outer surface of the pipe 28. The pipe 28 is supported by. By making contact with each other as described above, the pipe 28 warmed by a medium such as warm water passes through the pipe support portion 49 and warms the entire radiator plate 37, and further warms the tatami mat 5 attached to the upper portion of the radiator plate 37. Further, the surface of the tatami mat 5 is warmed by warming the tatami mat 5 through the heat dissipation holes 34 provided in the core material 33. The radiating hole 34 has a function of keeping the heat inside the tatami mat 5 and radiating heat to the upper part.
