Description

  TECHNICAL FIELD The present invention relates to a hot water mat for a vertical folding floor heating which is constructed on a floor of a room and can warm the room from the floor side.

  One or a plurality of floor heating hot water mats having a certain size is used in accordance with the size of the floor surface of the room.

  This is because hot water mats are manufactured at the factory and transported to the site or transported to the site building, and are too large to be brought into the elevator, or the room entrance is too narrow to be carried in. Because there is.

  In view of this, there is a conventional hot water mat that is formed in a foldable manner so as not to hinder the transport and carry-in.

  For example, in the hot water mat introduced in Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-65365), a slit is formed on the back surface of the hot water mat in parallel with the small joists inserted into the hot water mat, and bending is performed at the slit. I'm trying to wind it up.

  However, even in this case, there is a limit to downsizing since the small joists that are made of wood cannot be folded.

  Therefore, Patent Document 2 (Japanese Patent Application Laid-Open No. 2010-38390) introduced a hot water mat formed such that two hot water mats are added up and down in the length direction of the small joists and can be folded in half (mountain fold) in the middle. Yes.

  However, even in the case of the hot water mat disclosed in Patent Document 2, it is basically possible to add two individual hot water mats so that they are arranged one above the other, and then fold the mountain at this joint and fold it into two. In the same manner as in Patent Document 1 in which one mat is folded, the length in the small joist direction cannot be reduced in each of the upper and lower hot water mats.

  Further, even in the case of a so-called nedaless type hot water mat in which small joists are not inserted, the folding slit is provided in parallel with the hot water pipe as introduced in Patent Document 3 (Japanese Patent Application Laid-Open No. 2010-216727). Yes.

  Thus, in the case of the conventional hot water mat, since there is a limit to folding it, it is necessary to spread, for example, four hot water mats 1 as shown in FIG. 11 in the case of a large floor area. It was. In FIG. 11, reference numeral 2 is a mat body, 2a is a small joist, 3 is a piping groove, and 4 is a hot water pipe.

  However, when four hot water mats 1 are laid in this way, the number of U-turn portions 4b of the hot water pipe 4 increases, pressure loss increases, and connection of the hot water pipes 4 between the hot water mats 1 is necessary. There is a problem that not only the construction takes a lot of labor, but also it is likely to cause troubles such as water leakage, and the number of parts such as joint fittings for connection increases.

  Therefore, when considering an example in which the four hot water mats 1 described in FIG. 11 are configured in a two-sheet configuration, the width of the hot water mat 1 is the same as that of one sheet, and the length direction is two sheets. As a whole, there is a single long structure, and it is conceivable that construction is performed by arranging the long type in two rows on the left and right as shown in FIG.

  However, when the hot water mat 1 is formed in a long type as shown in FIG. 12, the number of meandering pitches of the hot water pipe 4 is increased and the length of the straight portion 4a is shortened. The manufacturing cost is high, and the number of U-turn portions 4b is increased, so that the pressure loss of the hot water pipe 4 is increased. 12 and 13, reference numeral 7 denotes a folding slit formed on the back surface of the mat body 2 in parallel with the straight portion 4 a of the hot water pipe 4.

JP 2000-65365 A JP 2010-38390 A JP 2010-216727 A

  The object of the present invention is to form a single warm water mat with a small width and a long belt shape in the vertical direction, and the hot water pipe has a straight portion arranged in the vertical direction to form a U-turn portion. It is to provide a hot water mat that can be accommodated with a minimum number of sheets in a large floor area by reducing the number, and that can be carried into an elevator or a room by being rolled up and downsized.

In order to achieve the above object, the invention according to claim 1 is a vertical folding hot water mat for floor heating, comprising: a. A freshly long flat mat body; b. On the surface of the mat body, the linear portion is formed in the longitudinal direction, and both ends of the adjacent linear portions are alternately connected by U-turn portions, so that the whole is meandering. Hot water pipe plumbing grooves, c. A hot water pipe which is piped in the pipe groove and dissipates heat through the hot water therein; d. A heat-dissipating sheet bonded to the entire surface of the mat body provided with the hot water pipe; e. A folding slit formed on the back surface of the mat body at regular intervals in a direction orthogonal to the straight line portion of the hot water pipe; f. Between the slits formed in the mat body, the mat bodies are alternately inserted so that the front ends from the left and right ends of the mat body do not reach the opposite ends of the mat body so as to be parallel to the slits. And a small joist having a U-shaped relief groove formed on the upper surface so as to escape from the hot water pipe at a position where the hot water pipe crosses the upper surface. It is.

  In the present invention, as described above, the hot water mat is formed to be long and the straight portion of the hot water pipe is arranged in the longitudinal direction of the hot water mat, and the U-turn portion is formed close to both end edges in the longitudinal direction. .

  As a result, the production cost and pressure loss can be greatly reduced by greatly reducing the number of straight portions and U-turn portions as compared with the hot water mat shown in FIG.

  In addition, since the length of the straight section of the hot water pipe is long, the length of the reverse Ω-shaped heat radiation tape to be attached to this straight section can be increased, so the thermal conductivity from the hot water pipe to the heat dissipation sheet is increased. A highly efficient hot water mat can be provided.

  In the hot water mat, since the slits are provided in a direction perpendicular to the length direction, the heat radiation sheet can be positioned inward and rolled up from the end in a roll shape. Even when the hot water mat has a length of 5 to 15 m and a length of 10 to 15 m, the roll diameter can be reduced to 60 to 80 cm when rolled up. As a result, it is possible to easily carry in and carry into the elevator or the room.

  Moreover, there is no problem in winding in a roll shape by inserting small joists parallel to the slits.

  The hot water mat of the present invention is constructed on the floor of a room and heats the floor surface with the heat of hot water of 60 ° C. to 80 ° C. circulating through the hot water pipe piped to the mat body to warm the room.

The mat body has a configuration in which a piping groove is formed on the upper surface of the foamed resin plate, and a hot water pipe made of resin is installed in the piping groove.

  And the heat dissipating sheet made of aluminum foil is pasted on the upper surface of the mat body after the piping, and this heat dissipating sheet distributes the heat of the hot water circulating in the hot water pipe uniformly over the entire surface of the hot water mat. Make the floor temperature uniform.

  In addition, a heat transfer tape made of aluminum foil with an inverted Ω-shaped cross section is attached to the lower half of the straight section of the hot water pipe, and this heat transfer tape heats the heat of the lower half surface hidden in the pipe groove of the hot water pipe. Is attached to the heat dissipation sheet to increase the thermal efficiency. However, there is also a hot water mat manufactured in a form in which this heat transfer tape is not mounted, and the present invention can be applied to both.

The hot water mat to which the present invention is applied is a type in which small joists are inserted , and a U-shaped hot water pipe escape groove is formed in the transverse portion so as to cross a straight portion of the hot water pipe.

  The slit formed on the back surface of the hot water mat is formed with a depth that leaves a part of the thickness of the mat body, or a depth that cuts the thickness of the mat body, or a combination of both. Although the winding diameter can be reduced, the strength of the mat body is reduced, so that the pitch is preferably about 10 to 25 cm. However, this pitch is determined according to the size of the hot water mat.

  The thickness of the mat body and the diameter of the hot water pipe are not limited in the application of the present invention, but the numerical values currently put into practical use are 12 mm for the mat body and 10 mm for the hot water pipe.

First, a nedaless type hot water mat in which a small joist is not inserted will be described with reference to FIGS. In the figure, reference numeral 1 denotes the whole hot water mat, 2 denotes a plate-like mat body formed of foamed resin, and the mat body 2 has a lateral width W = 2.5 m and a length L = 10 m.

  A cross section is formed on the upper surface of the mat body 2 so as to form U-turn grooves 3b alternately connecting the straight grooves 3a adjacent to the positions close to both ends 2b of the mat body 2 in the longitudinal direction of the mat body 2. A U-shaped piping groove 3 is formed.

  In FIG. 1, the piping groove 3 is represented by only one system, but there are more cases where two or more systems are formed.

  Reference numeral 4 denotes a hot water pipe piped in the pipe groove 3. Inside the hot water pipe 4, hot water generated by a heat source machine (not shown) is connected to conduits C, C 'and header B as shown in FIG. Circulate through. 4a is a straight portion of the hot water pipe 4, 4b is a U-turn portion, and in FIGS. 2 and 3, 6 is a heat radiation sheet attached so as to cover the entire top surface of the mat body 2.

  In FIG. 2, reference numeral 5 denotes an aluminum foil heat dissipation tape attached to the straight portion 4 a of the hot water pipe 4.

  Reference numeral 7 denotes a slit having a V-shaped cross section formed on the back surface of the mat body 2 in the thickness direction. The slit 7 is formed in the width direction of the mat body 2 (perpendicular to the straight portion 4a of the hot water pipe 4). 3) in parallel with a pitch of 20 cm as shown in FIG.

  The shape of the slit 7 may be I-shaped as shown in FIG. 6 (A) or U-shaped as shown in (B), or the entire thickness is cut as shown in (C). It may be formed.

  Or it is good also as a combination of the V, I, or U-shaped slit 7 of a present Example, and the cutting slit 7 shown to (C) as shown to (D).

  This is because when the mat body 2 is too long, it may be necessary to add one mat body 2 while adding the mat body 2, and the slit 7 in this case is just the mat body 2 at the added portion. The basis of the form is that the wall thickness of the film becomes a cut form.

  The hot water mat described above is laid in two rows on the left and right with respect to the floor A as shown in FIG. 4 as compared to the four-sheet use example of FIG. 11 described as an example of installing the conventional hot water mat in a large room. To respond. Of course, in the case of a large floor area, three or more sheets are arranged side by side.

  Further, when the hot water mat 1 is wound to be downsized, the heat radiating sheet 6 side is set inward as shown in FIG. When wound in this manner, the hot water mat 1 has a roll diameter of 70 cm and a roll length of 2.5 m. If it is this size, there is no problem in carrying it into a normal elevator or carrying it into a room.

Will now be described in detail with reference to the small joists containing hot water mat is in the present invention in FIGS. 7-9.

  The small joist 10 is inserted in parallel to the slit 7 in the mat body 2.

  A U-shaped escape groove 11 for escaping the hot water pipe 4 is formed on the upper surface of the small joist 10 as shown in FIG.

  The small joists 10 are inserted in the middle of the slits 7 every other in this embodiment, but may be inserted every two or more intervals.

  Further, in order to prevent the mat body 2 from being separated at the portion of the small joist 10, as shown in FIG. 10, as shown in FIG. By not doing so, the mat body 2 is secured.

  7 to 11, the same reference numerals as those in the first embodiment denote the same components, and thus the description thereof is omitted to avoid duplication of explanation.
