Description

Longitudinal folding floor heating mat {Rolled Floor Heating Mat Using Hydro}

The present invention relates to an elongated foldable floor heating hot water mat that can be constructed on the floor of a room to warm the room from the floor.

The hot water mat for floor heating is to use a single sheet or a plurality of sheets having a certain size in accordance with the size of the floor of the room.

This is because there is a problem that hot water mats are manufactured at the factory and returned to the site, or brought into the building of the site, which is too large to be brought into the elevator, or that the entrance of the room is narrow and cannot be brought in. .

Therefore, in the related art, a hot water mat is foldable so as not to interfere with the conveyance or the carrying in.

For example, in the hot water mat introduced in Patent Document 1 (Japanese Patent Laid-Open No. 2000-65365), a slit is formed on the rear surface of the hot water mat in parallel with a small floor support cross inserted into the hot water mat, and folded in this slit. I am winding up.

However, even in this case, there is a limit in miniaturization because the small floor support crosspiece, which is a wooden product, cannot be folded.

Therefore, Patent Document 2 (Japanese Patent Laid-Open No. 2010-38390) discloses a hot water mat formed by extending two sheets of hot water mats up and down in the longitudinal direction of a small floor support cross and folding them into two in the middle.

However, even in the case of the hot water mat of Patent Literature 2, the two individual hot water mats were extended so as to be arranged up and down, and only two mats were folded in two at this joint. In the same manner as in Patent Document 1, it is impossible to reduce the length of the small floor support cross direction in the upper and lower hot water mats, respectively.

In addition, even in the case of a so-called no-bar type hot water mat in which a small floor support crossbar is not inserted, as described in Patent Document 3 (Japanese Patent Laid-Open No. 2010-216727), the folding slit is parallel to the hot water pipe. Is installed.

As described above, in the case of the conventional hot water mat, since there is a limit to folding it small, in the case of a large floor area, for example, as shown in FIG. . In Fig. 11, reference numeral 2 denotes a mat main body, 2a denotes a small floor support crossbar, 3 denotes a pipe groove, and 4 denotes a hot water pipe.

However, when the four hot water mats 1 are laid on the front surface in this way, the number of U-turn portions 4b of the hot water pipe 4 increases, and the pressure loss increases, and between the hot water mats 1 The connection of the hot water pipe 4 is required, and not only it takes a lot of time in construction, but also causes a problem such as water leakage, and there is a problem that the number of parts such as joint metal balls of the connection part also increases.

Thus, considering an example in which the four sheets of hot water mat 1 described in Fig. 11 is configured in two sheets, the width of the hot water mat 1 is the same as one sheet, and the length direction is two sheets. The whole length is made into one piece long structure, and the method of constructing this long type thing is considered to be arranged in two rows of right and left as shown in FIG.

However, if the hot water mat 1 is formed in such a long type as in Fig. 12, as is obvious from Fig. 12, the pitch number of the serpentine shape of the hot water pipe 4 increases, and the length of the straight portion 4a is increased. Since it becomes short, manufacturing cost becomes expensive, and since the number of U turn parts 4b increases, the pressure loss of the hot water pipe 4 becomes large. 12 and 13, 7 is a slit for folding on the back surface of the mat main body 2 formed in parallel with the straight portion 4a of the hot water pipe.
