Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tatami floor for floor heating and cooling in which a fluid such as hot water or a refrigerant is circulated through a heat radiation tube to heat and cool the floor.

[Prior art]

Conventionally, various floor heating tatami mats have been proposed in which hot water pipes are buried in the tatami floor and hot water is circulated through the hot water pipes to heat the entire tatami mat.

By the way, the tatami floor usually used for the above-mentioned floor heating tatami mats is insulated fiber board specified in JIS A5905 or JIS A5913, JIS
Chemically finished tatami flooring using foam polystyrene boards (hereinafter referred to as "boards") specified in A5911 is often used.

[Problem that the invention attempts to solve]

However, with the prior art, among these boards, for example, insulated fiber boards, which expand and contract depending on the moisture content, dry the board by passing hot water through a hot water pipe. There is a drawback that the board shrinks and a gap is created between the tatami mats.

In particular, this type of floor heating tatami is made by stacking multiple boards to form the tatami floor, and if necessary, a heat transfer plate is interposed in contact with the hot water pipe, and the space between the boards is Since the structure is such that the heat exchanger plate is fixed with adhesive, etc., these boards are formed as one board in the front-rear, left-right directions, and the shrinkage of the outer edge of the tatami mat is reduced. The problem is that the absolute value of becomes very large.

The present invention was developed in view of the drawbacks of the chemical tatami flooring for floor heating and cooling according to the prior art described above, and is designed to prevent gaps from forming between tatami mats when they are laid in a room. The purpose is to provide tatami flooring for floor heating and cooling.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention consists of an upper board made by dividing a board with the size of one tatami mat into a plurality of board pieces into which a tatami needle can be inserted; A lower board consisting of a plurality of boards and having the size of one tatami mat to be overlapped with the upper board, and a lower board located on the upper surface side of the lower board so as not to interfere with the processing of the tatami surface. a pipe groove for arranging a heat dissipation pipe formed within a predetermined range with respect to the periphery of the pipe, a heat dissipation pipe disposed within the pipe groove, and the upper board and the lower board so as to be in contact with the heat dissipation pipe. The heat transfer plate and the upper board are sequentially placed on a heat transfer plate made of metal foil that is provided between them and into which a tatami needle can be inserted, and a heat dissipation tube is arranged in the pipe groove of the lower board. The tatami thread is sewn together to form a tatami floor when the tatami floor is placed in place.

[Effect]

With this configuration, it is possible to manufacture a tatami floor by sewing together the multiple board pieces that make up the upper board, the lower board, and the heat transfer plate using tatami yarn, and it is possible to manufacture a tatami floor during the process of using it as a tatami floor. Even if the upper board shrinks due to drying, etc., the absolute value of the shrinkage of each board piece can be kept small, and the heat dissipation pipes are only buried within a predetermined range around the periphery of the tatami floor. Therefore, there is no hindrance when the tatami face and edge of the tatami are sewn by a tatami shop, and the tatami can be treated in the same way as regular rice straw tatami.

This is to prevent the heat dissipation tube 4 from moving and damaging the brazed portion.

Reference numeral 7 denotes a heat transfer plate interposed between the upper board 1 and the lower board 2. The heat transfer plate 7 contacts the heat radiation tube 4 to transfer heat over the entire surface of the upper board 1. As the heat transfer plate 7, aluminum foil is used so that the tatami needle can be easily inserted. In the case of this example, the aluminum foil has a width of 910 mm and a thickness of 0.15 mm.
A roll of aluminum foil cut into lengths of 1820 mm is used. Note that the heat transfer plate 7
Instead of aluminum foil, copper foil, ultra-thin iron foil, etc. may be used, and any metal foil that allows the insertion of a tatami needle may be used.

Reference numeral 8 denotes an insect-proof and moisture-proof back material provided on the bottom side of the lower board 2 (see FIGS. 5 and 6).

Next, the process of manufacturing a tatami floor using each of the above-mentioned members will be described.

First, as a preparatory work, the upper board 1 is cut into six board pieces 1A to 1F as shown in FIG.
A pipe groove 3 as shown in FIG. 4 is formed on the lower board 2. On the other hand, in order to use it as a heat dissipation tube 4, a copper tube or the like is placed in the tube groove 3.
The pipe is bent to match the pipe end, and adapters 5, 5 are brazed to the pipe ends.

Next, place back material 8 and lower board 2 on the tatami floor processing table.

Then, the heat dissipation tube 4 is placed in the tube groove 3, and the rubber ring 6 and the adapter 5 are inserted into the adapter attachment hole 3A. On top of that, a heat exchanger plate 7 made of aluminum foil,
A tatami floor 10 as shown in FIG. 1 is manufactured by sequentially placing an upper board 1 consisting of board pieces 1A to 1F and sewing them together with tatami threads 9 using a tatami floor manufacturing machine. Can be done. Note that the feed width of the tatami needle is set so that the tatami needle does not hit the heat dissipation tube 4 when sewing with the tatami bed manufacturing machine.

Finally, the tatami floor 1 assembled as described above
0, after adding markings (for example, length 1580 mm, width 700 mm) indicating the buried range of the heat dissipation tube 4,
The products are inspected, packaged, and shipped to various tatami stores.

Now, the tatami floor 10 manufactured as described above
Tatami Omote 11, Tatami Edge 12,1 are available at tatami stores in each region.
By sewing 2, as shown in Figure 2,
It can be processed as tatami mat 13 for heating and cooling. At this time, the heat dissipation pipe 4 is housed within a range of 1560 mm in length and 680 mm in width, and the heat dissipation pipe 4 does not exist in the position where the tatami hem 12 should be sewn, so it will not cause any hindrance to the processing of the tatami facing 11. There isn't.

In this embodiment, the upper board 1 is divided into six board pieces 1A to 1F, so that even if hot water is passed through the heat radiation pipe 4, the shrinkage of the heating/cooling tatami 13 as a whole is minimized. may be limited.

That is, Fig. 7 is an explanatory diagram showing the state of shrinkage of the conventional tatami floor manufactured by overlapping non-divided boards. It is assumed that the tatami floor dries (moisture content decreases) by passing hot water and shrinks by ΔL in the longitudinal direction. Now, assuming that the shrinkage rate of the board when the moisture content changes by 1% is 0.02 to 0.03%, and the maximum decrease in moisture content due to drying is 10%, the tatami mats in the Edo room (length 1760 mm, width 880 mm) It will shrink by up to 5.2mm, and the maximum value of ΔL will be 2.6mm.

However, in this embodiment, since the upper board 1 is divided as shown in FIG. 3, the shrinkage state of the front side of the tatami floor 10 in this embodiment is as shown in FIG. 8, and the longitudinal direction is ΔL. It shrinks by only /4, and the absolute value of the shrinkage margin can be set to 1/4.
Thus, in this embodiment, even though the heat dissipation pipe 4 is disposed within the tatami floor 10, the shrinkage of the tatami as a whole can be suppressed to a small level, and no gaps are generated between the tatami mats. In addition, by sewing the upper board 1 and the lower board 2 together with the tatami yarn 9 in the state shown in Fig. 1, the absolute value of the shrinkage margin can be kept small. Needless to say, such an effect cannot be achieved.

Further, in this embodiment, since the heat transfer plate 7 is used between the upper board 1 and the lower board 2, the surface temperature of the tatami surface 11 can be made uniform. Moreover, by using aluminum foil for the heat transfer plate 7, there is no problem in inserting the tatami needle when processing the tatami floor using the tatami yarn 9, and a conventional tatami floor manufacturing machine can be used. can do. Furthermore, when sewing together the tatami floor 10, a large number of holes (approximately 400) are formed in the aluminum foil to ensure breathability.

Furthermore, the heat dissipation tube 4 has a length of 1560 mm as shown in Figure 4.
Because they are arranged within a width of 680 mm, when processing tatami mats at a tatami store, you can work with the same feeling as tatami mats made from rice straw. Moreover, even if the tatami is in an Edo room, there will be a 100 mm wide area around the area where no heat dissipation pipe 4 is present, and the tatami hem 12 can be sewn smoothly.

In addition, in the embodiment, the upper board 1 is described as being divided into six board pieces 1A to 1F, but it may be divided into two to five board pieces.
It may be divided into 7 or more pieces. Further, in the embodiment, the tube groove 3 and the heat dissipation tube 4 are formed in a meandering shape, but a header type in which the heat dissipation tubes are arranged in parallel may be used. Furthermore, the tube end position of the heat dissipation tube 4 is not limited to the position shown in FIG. 1, but may be at a diagonal position as shown in FIG. 9A, or may be located at the center in the longitudinal direction as shown in FIG. 9B. Furthermore, the lower board 2 is not limited to being composed of one board, but may include an upper lower board 21 having a pipe groove 3 formed therein as shown in FIG.
The lower board 22 located below the upper and lower boards 21 may be stacked vertically, and in short, the lower board with the heat transfer plate 7 as the boundary is the upper board 1.
without being split into multiple board pieces as in
It suffices if it is undivided over the entire surface.

[Effect of idea]

As described in detail above, the tatami floor for floor heating and cooling according to the present invention is made by dividing the upper board into a plurality of board pieces,
Since the structure is such that the heat exchanger plate and heat dissipation tube are sandwiched between each board piece and the lower board piece and sewn together with tatami yarn, it is not only easy to process the tatami floor using tatami yarn, but also the upper Since the board is divided into multiple board pieces, it is possible to reduce the shrinkage of the outer circumference of the tatami floor due to drying, etc., and it is possible to eliminate gaps between tatami mats when the tatami mats are used for heating and cooling purposes. Furthermore, since there are no heat dissipation pipes buried in the periphery of the tatami floor, when processing the tatami face and edges of tatami mats at a tatami store, the work can be done in the same way as when processing regular rice straw tatami floors. It has the effect of
