At the time of construction of the hot water heating device, a plurality of hot water heating pipes passed through the foundation through hole are connected to the hot water forward header and the hot water return header. The hot water heating device is installed close to the outer wall of the building where the foundation through hole is provided, and the part extending to the outside from the foundation through hole of multiple hot water heating pipes is shortened so as not to be visible as much as possible so as not to spoil the aesthetic appearance. ing. However, since the short hot water heating pipe is bent and connected, and since a plurality of hot water heating pipes are connected in a narrow connection space of the hot water heating device, the burden of connecting the pipes is large. On the other hand, in terms of appearance, when a plurality of hot water heating pipes intersect, it tends to give a messy impression, which may spoil the aesthetic appearance.

An object of the present invention is to provide a hot water heating header capable of connecting hot water heating pipes so as not to spoil the aesthetic appearance and reducing the burden of connection work.

The hot water heating header of the invention of claim 1 includes a hot water forward header that distributes high temperature water supplied from the hot water heating device to a plurality of heating terminals, and a low temperature that is dissipated by the plurality of heating terminals and returns to the hot water heating device.

It is characterized by that.
According to the above configuration, since the pair of hot water heating pipes extending from one heating terminal can be easily connected to one discharge introduction pair, it is difficult to make a mistake in the connection and the burden of the work of connecting the pipes is reduced. ..

According to the above configuration, since the foundation through hole is blocked by the header body, the plurality of hot water heating pipes extending from the plurality of heating terminals cannot be seen hidden inside the foundation, and only two pipes can be seen, which gives a messy impression. It is difficult to give, and it is possible to prevent the appearance from being spoiled. Further, since the foundation through hole is blocked by the header body, it is possible to prevent foreign substances such as pests from entering the underfloor space of the building.

Hereinafter, embodiments for carrying out the present invention will be described based on examples.

As shown in FIG. 1, the foundation B of the building is provided with a plurality of foundation through holes T1 and T2 that communicate the underfloor space inside the foundation B with the outside of the building in order to pass cords, pipes, and the like. .. A hot water heating header 1 is attached to the foundation through hole T1, and a hot water heating device 2 is installed near the header 1. A plurality of heating terminals H1 and H2 are installed in the building. A hot water supply pipe or the like of a hot water supply device is passed through the foundation through hole T2, and when the foundation through hole T2 is not used, a closing lid is attached.

The hot water outflow pipe 3 and the hot water return pipe 4 are connected from the hot water heating device 2 to the hot water heating header 1. The hot water going pipe 3 supplies high-temperature water for heating from the hot water heating device 2 to a plurality of heating terminals H1 and H2 in the building via the hot water heating header 1. The hot water return pipe 4 collects the low-temperature water radiated by the plurality of heating terminals H1 and H2 via the hot water heating header 1 and returns it to the hot water heating device 2. Further, hot water heating pipe pairs 5 and 6 extending from the heating terminals H1 and H2 are connected to the hot water heating header 1. A quick fastener, a coupling clamp, or the like is used to connect the hot water heating header 1 to the pipe.

The hot water heating pipe pair 5 is a hot water heating pipe 5a for supplying high temperature water to the heating terminal H1 and a hot water heating pipe 5b for collecting the low temperature water radiated by the heating terminal H1 on the other side. Similarly, the hot water heating pipe pair 6 also has a hot water heating pipe 6a for high temperature water and a hot water heating pipe 6b for low temperature water. As described above, the hot water heating device 2 and the plurality of heating terminals H1 and H2 are connected to each other via the hot water heating header 1 to form a hot water heating system. Although not shown, the wiring for communication between the heating terminals H1 and H2 and the hot water heating device 2 is also connected through the foundation through holes T1 and T2 or the openings in the wall of the building.

Although not shown, the hot water heating device 2 includes a heat source device and a pump. Then, the pump is driven to supply the high-temperature water heated by the heat source machine to the heating terminals H1 and H2 via the hot water heating header 1, and the low-temperature water is recovered from the heating terminals H1 and H2. As the heat source machine, a combustion type, a heat pump type, a heat source machine that utilizes exhaust heat such as power generation, or the like can be used. Although the description is omitted, the heating terminals H1 and H2 are a floor heating device that uses hot water, a hot air heater, a convector heater, and the like.

As shown in FIGS. 2 to 4, the hot water heating header 1 has a disk-shaped header body 7, a first header 8 and a second header 9, and the header body 7 includes a first header 8 and a second header. 9 is integrally formed. The header body 7 has a disk shape having a diameter slightly smaller than the inner diameter (for example, 100 mm) of the foundation through hole T1, but may be formed in a columnar shape having a thickness thicker than this.

The first and second headers 8 and 9 can switch the role of the hot water forward header that distributes the hot water and the role of the hot water return header that collects the low temperature water depending on the flow direction of the hot water. In the following, the first header 8 will be referred to as a hot water forward header 11 and the second header 9 will be referred to as a hot water return header 12, and the description of the case where the hot water flow directions are reversed and the roles are exchanged will be omitted.

The hot water forward header 11 includes one high-temperature water introduction port 11a, a plurality of high-temperature water discharge ports 11b to 11e, and a distribution passage 11f for distributing high-temperature water from the high-temperature water introduction port 11a to a plurality of high-temperature water discharge ports 11b to 11e. Have. The hot water return header 12 includes one low-temperature water discharge port 12a, a plurality of low-temperature water introduction ports 12b to 12e, and a collecting passage 12f for collecting low-temperature water from the plurality of low-temperature water introduction ports 12b to 12e to the low-temperature water discharge port 12a. Have. The plurality of high-temperature water discharge ports 11b to 11e are the same number as the plurality of low-temperature water introduction ports 12b to 12e, and each of them is four, but each may be three, and each may be five or more.

The high temperature water introduction port 11a is arranged in the center of the header main body 7, and the high temperature water introduction port 11a and the low temperature water discharge port 12a extend from the header main body 7 in the same direction. The plurality of high-temperature water discharge ports 11b to 11e and the plurality of low-temperature water introduction ports 12b to 12e extend from the header main body 7 to the opposite sides of the high-temperature water introduction port 11a and the low-temperature water discharge port 12a, respectively. Hereinafter, the side of the header body 7 where the high temperature water introduction port 11a and the low temperature water discharge port 12a are located is the hot water heating device side, and the side where the plurality of high temperature water discharge ports 11b to 11e and the plurality of low temperature water inlet ports 12b to 12e are located is heated. I will call it the terminal side.

Of the plurality of high-temperature water discharge ports 11b to 11e and the plurality of low-temperature water introduction ports 12b to 12e, the plurality of high-temperature water discharge ports 11b to 11e (one) are located near the center of the header body 7 from the center of the header body 7. They are arranged so as to be separated by the same distance in the radial direction and evenly positioned in the circumferential direction. The plurality of low-temperature water inlets 12b to 12e (the other) are arranged outside the central vicinity thereof so as to be concentrically arranged with respect to the plurality of high-temperature water discharge ports 11b to 11e.

The distribution passage 11f extends radially from the center of the header body 7 communicating with the high temperature water introduction port 11a to the plurality of high temperature water discharge ports 11b to 11e on the heating terminal side of the header body 7. The collecting passage 12f extends so as to pass through positions corresponding to the plurality of low-temperature water introduction ports 12b to 12e on the hot water heating device side of the header main body 7 and communicates with the low-temperature water discharge port 12a. Here, the low-temperature water discharge port 12a is provided at a position corresponding to the low-temperature water introduction port 12c, but the low-temperature water discharge port 12a may be arranged at an arbitrary position in the collecting passage 12f. Further, although the gathering passage 12f is provided in a polygonal line shape, the gathering passage 12f may be provided in an arc shape along the outer edge portion of the header body 7.

The high-temperature water introduction port 11a, the low-temperature water discharge port 12a, and the collecting passage 12f are formed in the hot water heating device side member 7a constituting the header main body 7. The plurality of high-temperature water discharge ports 11b to 11e, the plurality of low-temperature water introduction ports 12b to 12e, and the distribution passage 11f are formed in the heating terminal side member 7b constituting the header main body 7. These are laminated and integrated to form a hot water heating header 1.

For example, the hot water heating pipe pair 5 extending from the heating terminal H1 is connected to the hot water heating header 1 in a state of being pulled out from the foundation through port T1. At this time, according to the hot water distribution direction of the heating terminal H1, the hot water heating pipe 5a is connected to one of the high temperature water discharge ports 11b to 11e, and the hot water heating pipe 5b is among the low temperature water introduction ports 12b to 12e. Connected to one of. No matter which high-temperature water discharge port or low-temperature water introduction port is connected, there is basically no problem as long as the distribution direction is correct. However, when connecting a pair of hot water heating pipes of a plurality of heating terminals, there is a risk that the connection may be mistaken or forgotten.

Therefore, for example, a discharge introduction pair 13b having a high temperature water discharge port 11b and a corresponding low temperature water introduction port 12b is formed so that the connection can be reliably performed and the confirmation can be easily performed. The discharge introduction pair 13b is formed by aligning the low temperature water introduction port 12b corresponding to the high temperature water discharge port 11b in the radial direction from the center of the header body 7. Similarly, discharge introduction pairs 13c to 13e are formed for the low temperature water introduction ports 12c to 12e corresponding to the other high temperature water discharge ports 11c to 11e.

For example, in the hot water heating header 1 in which the hot water heating pipe pairs 5 and 6 are connected to the discharge introduction pairs 13b and 13d, respectively, and all the hot water heating pipe pairs are connected to the discharge introduction pair, the unconnected discharge introduction pair. A closing plug (not shown) for preventing the outflow of hot water is attached to 13c and 13e, respectively. A hot water outflow pipe 3 connected to a high temperature water supply port of the hot water heating device 2 is connected to the high temperature water introduction port 11a of the hot water heating header 1. Further, a hot water return pipe 4 connected to the low temperature water recovery port of the hot water heating device 2 is connected to the low temperature water discharge port 12a of the hot water heating header 1.

The hot water heating header 1 after connecting all the pipes pushes the hot water heating pipe pairs 5 and 6 back inside the foundation B and is housed in the foundation through hole T1. Then, the outer edge portion of the header body 7 is fixed to the inner peripheral wall portion of the foundation through hole T1 by, for example, a caulking agent, and the foundation through hole T1 is closed. The hot water outflow pipe 3 and the hot water return pipe 4 are, for example, bent upward and connected to the hot water heating device 2.

When the header body 7 is thickly formed and has a columnar shape, the posture of the hot water heating header 1 can be easily stabilized in the foundation through hole T1, so that the connection work becomes easy. If the hot water heating header 1 cannot be inserted into the foundation through hole T1, it may be fixed to the foundation B by a caulking agent on the hot water heating device side of the foundation through hole T1 to close the foundation through hole T1. Good.

The plurality of hot water heating pipe pairs 5 and 6 extending from the plurality of heating terminals H1 and H2 are hidden inside the foundation B and cannot be seen. You can only see the plumbing. Therefore, there is almost no possibility that these pipes give a messy impression, and the aesthetic appearance is not spoiled. Further, since the hot water heating device 2 is connected to the two pipes of the hot water outflow pipe 3 and the hot water return pipe 4, the pipe connection work is facilitated in the narrow connection space of the hot water heating device 2 and the burden is reduced. Will be done.

Since the foundation through hole T1 is blocked by the header body 7 of the hot water heating header 1, it is possible to prevent foreign substances such as pests from entering the underfloor space of the building through the foundation through hole T1. At this time, as compared with the conventional connection mode in which the hot water heating header 1 is not used, it is not necessary to fill the gap between the plurality of pipes and the gap between the plurality of pipes and the inner wall of the foundation through hole with a caulking agent or the like. Therefore, the foundation through hole can be easily and surely closed.

The heating terminal may not have a closing mechanism for closing the hot water for heating so as not to circulate. In the hot water heating header 1, a thermal valve is attached to at least a part of the low temperature water introduction ports so that the start and stop of the supply of high temperature water to the heating terminal can be controlled. Can be done. For example, as shown in FIG. 5, the low temperature water introduction port 12b is equipped with the thermal valve 14.

The thermal valve 14 advances the rod 14a by utilizing the expansion of the thermoelement heated by energization, and separates the valve body 14b at the tip of the rod 14a from the valve seat 14c to allow the fluid to flow. When the energization is stopped, the thermoelement contracts, the rod 14a retracts due to the return spring 14d, the valve body 14b comes into close contact with the valve seat 14c, and the fluid flow is stopped.

In this way, it is possible to control the flow of hot water for heating in the heating terminal H1 connected to the low temperature water introduction port 12b provided with the thermal valve 14. When the low-temperature water discharge port 12a is arranged at a position that does not correspond to any of the low-temperature water introduction ports 12b to 12e in the collecting passage 12f, the thermal valves 14 are installed in all the low-temperature water introduction ports 12b to 12e, respectively. Can be equipped.

The operation and effect of the hot water heating header 1 of the present invention will be described.
The hot water heating header 1 is formed by integrating the hot water outgoing header 11 and the hot water returning header 12 with the header main body 7. A plurality of heating pipes 5a, 5b, 6a, 6b extending from the plurality of heating terminals H1 and H2 are connected to the hot water heating header 1, and the hot water heating header 1 and the hot water heating device 2 are connected to the hot water outbound pipe 3. It can be connected with two pipes of the hot water return pipe 4. Therefore, it is possible to reduce the burden of the work of bending and connecting the pipe to the hot water heating device 2.

Further, since the plurality of high-temperature water discharge ports 11b to 11e are grouped in the vicinity of the center of the header main body 7, when connecting the plurality of hot water heating pipes 5a, 5b, 6a, 6b of the heating terminals H1 and H2, , It becomes difficult to mistake the high temperature water discharge port and the low temperature water introduction port, and the burden of the work of connecting the pipes is reduced.

In the hot water heating header 1, the high temperature water discharge ports 11b to 11e and the low temperature water introduction ports 12b to 12e are aligned radially from the center of the header body 7 to form discharge introduction pairs 13b to 13e. Therefore, by connecting the hot water heating pipe pair 5 of the heating terminal H1 to, for example, the discharge introduction pair 13b, and connecting the hot water heating pipe pair 5 of the heating terminal H2 to, for example, the discharge introduction pair 13d, it becomes difficult to make a mistake in the connection, and the pipes are connected. The burden of connecting work can be reduced. Even if the number of heating terminals increases more than this, the burden of the work of connecting the pipes can be similarly reduced.

The hot water heating header 1 is attached so that the header body 7 is formed in a disk shape or a columnar shape and closes the circular foundation through hole T1 of the building. Therefore, the plurality of pipes 5a, 5b, 6a, 6b extending from the heating terminals H1 and H2 are hidden inside the foundation B and cannot be seen, and only two pipes, the hot water outflow pipe 3 and the hot water return pipe 4, can be seen, which is messy. It is difficult to give a good impression, and it is possible to prevent the appearance from being spoiled.

Further, since the foundation through hole T1 is blocked by the header body 7, it is possible to prevent foreign substances such as pests from entering the underfloor space of the building through the foundation through hole T1. Further, since it is not necessary to fill the gap between the plurality of pipes and the gap between the plurality of pipes and the inner wall of the foundation through hole with a caulking agent or the like, the foundation through hole T1 can be easily and surely closed. ..

In the hot water heating header 1, a thermal valve 14 is attached to at least a part of a plurality of high temperature water discharge ports 11b to 11e or a plurality of low temperature water introduction ports 12b to 12e. Therefore, for example, the flow of hot water in the heating terminal H1 connected to the low temperature water introduction port 12b equipped with the thermal valve 14 can be controlled by the hot water heating header 1.

Even if the pipes are connected so that the hot water flow direction of the hot water heating header 1 is opposite to the above and the roles of the first and second headers 8 and 9 are exchanged, the same function as described above can be achieved. Further, a wiring insertion portion is formed by cutting out a part of the outer edge portion of the header main body 7, and for example, the wiring for communication between the heating terminals H1 and H2 and the hot water heating device 2 is passed through the wiring insertion portion to connect the wiring. It is possible to reduce the burden of connecting work and not to spoil the aesthetic appearance. In addition, a person skilled in the art can carry out the embodiment in a form in which various modifications are added to the above embodiment without departing from the spirit of the present invention, and the present invention includes such modified embodiments.
