JP 2000-248731

  In the conventional integrated floor heating panel, the hot water circulation pipe is extended linearly over almost the entire length in the longitudinal direction of the substrate and is folded at almost both ends in the longitudinal direction, so that the hot water circulation pipe in the width direction of the substrate is The number of overlaps was too large over almost the entire length in the longitudinal direction. Therefore, there are too many grooves for accommodating the hot water circulation pipe, the strength of the substrate is impaired, and the substrate may be bent in the width direction.

  In addition, since the linearly extending portions of the hot water circulation pipe were continuously arranged in parallel, one end side (the side to which hot water is first supplied) and the other end side (the hot water are supplied) in the width direction of the substrate There is a problem that the temperature difference between the substrate and the substrate on which the substrate is supplied last becomes too large, resulting in uneven temperature on the substrate.

  Therefore, a main object of the present invention is to provide an integrated floor heating panel that can prevent deformation (curvature) of a substrate. Another object of the present invention is to provide an integrated floor heating panel capable of eliminating the temperature unevenness of the substrate.

The invention described in claim 1 is “warm water flowing through the hot water circulation pipe 18, including the panel body 16 including the long plate-like substrate 20 in which the groove 22 is formed and the hot water circulation pipe 18 accommodated in the groove 22. The floor heating panel 12 is an integrated floor heating panel 12 configured to transmit the heat of the hot water circulation pipe 18 and the hot water circulation pipe 18 is extended in the longitudinal direction of the substrate 20. The first heating unit 28 a, the second heating unit 28 b, and the third heating unit 28 c having the linear portion 32 configured in this manner are arranged in this order in the longitudinal direction of the substrate 20, and hot water in the width direction of the substrate 20 overlap number of circulation pipe 18 is partially reduced in the longitudinal direction of the substrate 20, the hot water and the second heating part 28b, a third heating unit 28c, it flows in the order of the first heating unit 28a It is configured, an integrated floor heating panel 12 ".

  In the present invention, since the number of overlapping hot water circulation pipes 18 in the width direction of the substrate 20 is partially reduced in the longitudinal direction of the substrate 20, the number of grooves 22 can be reduced in the reduced portion. The strength of the substrate 20 can be increased. The “number of overlapping hot water circulation pipes in the width direction of the substrate” refers to the number of grooves intersecting with the virtual straight line, assuming a virtual straight line extending in the width direction of the substrate.

Moreover, since the heat of warm water is given in order of the center part of the longitudinal direction in the board | substrate 20, the other end part, and one end part, a center part becomes the highest temperature, one end part becomes the lowest temperature, and the other end part is intermediate | middle. Temperature. Accordingly, the temperature difference in the substrate 20 is reduced by exchanging heat between the central portion of the highest temperature and the one end portion of the lowest temperature.

  According to the first aspect of the present invention, since the number of grooves can be reduced in the portion where the number of overlapping hot water circulation pipes is reduced, the strength of the substrate can be increased in that portion, and the substrate is deformed (curved). ) Can be prevented.

In addition, since the temperature difference in the substrate can be reduced, uneven temperature in the substrate can be eliminated.

  The panel unit 10 shown in FIG. 1 is configured by combining two integrated floor heating panels 12 and 14 to which the present invention is applied, and a plurality of panel units 10 are laid on the floor. A floor heating system A as shown in FIG. 5 is constructed. Since the two integrated floor heating panels 12 and 14 are common in the basic configuration, the one integrated floor heating panel 12 will be described in detail first, and then the other integrated floor heating panel. The panel 14 will be briefly described focusing on the differences.

  As shown in FIGS. 2 and 3, the integrated floor heating panel 12 includes a panel body 16 having a heat conduction function and a decoration function, and a hot water circulation pipe 18 having a heating function using hot water.

  The panel body 16 (FIGS. 2 and 3) is made of a single wood plate, plywood, MDF (medium density fiber board), HDF (high density fiber board), wood chipboard, synthetic resin board, or a composite board thereof. A long plate-like substrate 20 is included, and protrusions 20a are formed on two orthogonal sides of the substrate 20, and grooves 20b (FIG. 3) are formed on the other two orthogonal sides of the substrate 20. Has been. Further, a groove 22 for accommodating the hot water circulation pipe 18 is formed on the back surface of the substrate 20. A sheet-like or film-like heat equalizing material 24 having excellent thermal conductivity, such as aluminum, is affixed to the back surface of the substrate 20 and the inner surface of the groove 22. A surface material 26 made of a decorative veneer such as Tamo, China, hippo or the like, or a WPC processed veneer is attached.

  The depth and width of the groove 22 are set to be slightly larger than the diameter of the hot water circulation pipe 18, and the shape of the meander line drawn by the groove 22 is set to correspond to the piping shape of the hot water circulation pipe 18 described later. ing.

  The hot water circulation pipe 18 heats the substrate 20 with hot water flowing through the hot water circulation pipe 18 and is continuously formed of a flexible material such as crosslinked polyethylene. The warm water circulation pipe 18 constitutes a first heating unit 28a, a second heating unit 28b, and a third heating unit 28c. Each of the heating units 28a, 28b, and 28c has a bending portion 30 configured by bending the hot water circulation pipe 18 and a linear portion 32 configured by extending the hot water circulation pipe 18 in the longitudinal direction of the substrate 20. These heating units 28 a, 28 b and 28 c are arranged in this order in the longitudinal direction of the substrate 20.

  The inlet side end of the second heating unit 28 b communicates with the hot water supply unit 34 drawn out from the longitudinal edge of the substrate 20, and the outlet side end of the second heating unit 28 b connects the connecting unit 36. Via the connecting part 38 and communicates with the inlet side end of the first heating part 28a through the connecting part 38. . Further, the outlet side end portion of the first heating unit 28 a communicates with the discharge unit 40 drawn out from the width direction end edge of the substrate 20. The overlapping number of the hot water circulation pipes 18 in the width direction of the substrate 20 is partially reduced in the longitudinal direction of the substrate 20. In this embodiment, the reference overlapping number is “4”, and the overlapping number is Is partially reduced to “two” (FIGS. 2 and 3).

  Since the shape of the “meandering line drawn by the groove 22” described above corresponds to the piping shape of the hot water circulation pipe 18, the number of the grooves 22 is reduced in the portion where the number of overlapping hot water circulation pipes 18 is reduced. As a result, the strength of the substrate 20 is increased. That is, generally, when the grooves 22 are formed in the substrate 20, the thickness of the substrate 20 is reduced and the strength is reduced at that portion. In this embodiment, the number of the grooves 22 arranged in the width direction of the substrate 20 Since it can reduce partially, the intensity | strength of the board | substrate 20 can be raised.

  As shown in FIG. 4, the other integrated floor heating panel 14 includes a panel body 44 including a substrate 42 in which grooves are formed, and a hot water circulation pipe 18 through which hot water flows. The basic configuration of the integrated floor heating panel 14 is the same as that of the integrated floor heating panel 12 described above, and both differ in the shapes of the hot water supply units 34 and 46 and the discharge units 40 and 48 in the hot water circulation pipe 18. .

  That is, in the panel unit 10, since hot water is continuously supplied to the integrated floor heating panels 12 and 14, the discharge part 40 of one integrated floor heating panel 12 and the other integrated floor heating panel 14. It is necessary to connect to the hot water supply section 46 of this. Therefore, in order to facilitate this connection, the hot water supply portion 46 of the integrated floor heating panel 14 is drawn out from the edge in the width direction of the substrate 42. Moreover, since the integrated floor heating panels 12 and 14 are combined in a state shifted from each other in the longitudinal direction, in the integrated floor heating panel 14, the location where the hot water supply unit 46 is pulled out and the longitudinal edge of the substrate 42. A space S (FIG. 4) is generated between the two. Therefore, the fourth heating section 50 is configured by meandering the hot water circulation pipe 18 (discharge section 48) in order to give warm water heat to the space S as well.

  When assembling the panel unit 10 (FIG. 1), first, the discharge part 40 of one integrated floor heating panel 12 and the hot water supply part 46 of the other integrated floor heating panel 14 are connected, and then one of the one integrated floor heating panel 14 is connected. The protrusion 20a of the body-type floor heating panel 12 and the groove 52b of the other integrated floor heating panel 14 are fitted together. When the floor heating system A (FIG. 5) is constructed using the panel unit 10 (FIG. 1), first, the ridges 52a of the integrated floor heating panel 14 in the one panel unit 10 and the other panel unit. 10 are fitted together with the groove 20b of the integrated floor heating panel 12 to join the plurality of panel units 10 to each other. Subsequently, the hot water circulation pipe 18 of each panel unit 10 is connected to the hot water supply apparatus.

  When heating is performed using the floor heating system A (FIG. 5), hot water is supplied from the hot water supply device to the hot water circulation pipe 18 of each panel unit 10. Then, in the integrated floor heating panels 12 and 14, warm water is supplied in the order of the second heating unit 28b, the third heating unit 28c, and the first heating unit 28a, and the substrate 20 is heated by this warm water.

  At this time, the temperature of the hot water discharged from the discharge port of the hot water supply apparatus is the highest immediately after discharge, and is cooled and lowered as it moves away from the discharge port. Therefore, in the integrated floor heating panels 12 and 14, Is first supplied, the temperature of the second heating unit 28b is the highest, then the temperature of the third heating unit 28c is the highest, and the temperature of the first heating unit 28a is the lowest. Accordingly, the second heating unit 28b having the highest temperature and the first heating unit 28a having the lowest temperature are adjacent to each other, and heat exchange is performed between the second heating unit 28b and the first heating unit 28a through the substrate 20, thereby causing a temperature difference in the substrate 20. As a result, the temperature unevenness of the substrate 20 is eliminated.

  In the above-described integrated floor heating panels 12 and 14, hot water is supplied in the order of the second heating unit 28b, the third heating unit 28c, and the first heating unit 28a. For example, as shown in FIG. 6, the first heating unit 28a, the second heating unit 28b, and the third heating unit 28c may be supplied in this order. Moreover, the number of the heating parts 28 can be changed as appropriate. For example, as shown in FIG. 7 or 8, the number may be two, or four or more (not shown). Furthermore, the shape of the heating unit 28 can be changed as appropriate, and may be L-shaped, for example, as shown in FIG. Even in these cases (FIGS. 6, 7, and 8), the number of overlapping hot water circulation pipes 18 in the width direction of the substrate is partially reduced in the longitudinal direction of the substrate. The strength of the substrate can be increased.
