This hot water supply pipe (3) can be made of a steel pipe or the like as appropriate, but it has a corrugated shape,
Arrange it by bending it into a meandering shape or other appropriate shape (
(See Figure 2.1). Furthermore, in terms of the heating effect due to improved thermal conductivity, the wider the contact area with the steel plate (1), the better the heating efficiency will be. Therefore, there is no absolute necessity for the hot water supply pipe (3) to have a cylindrical cross-sectional shape as shown in FIG. Considering the difficulty of workability aside, if the shape is square, the contact area with the steel plate (1) will be larger and the heating effect will be improved. This hot water supply pipe (3) is provided with flow rate regulating valves (4) as shown in FIG. 4 at appropriate locations on the hot water supply pipe (3). This makes it possible to adjust the heating temperature and even in the summer when heating is not required. still.

A heat insulating material (5) is arranged on the lower surface of the steel plate (1) and the hot water supply pipe (3). As the heat insulating material (5), resins such as hard polyurethane are suitable for use, but are not limited thereto. Any material can be used as long as it prevents the heat emitted from the hot water supply pipe (3) from being emitted to areas other than the floor surface and provides a heat insulating effect. The panel substrate (6) has such a configuration.

The panel substrate (6) may be formed by integrally pouring resin. For such a panel substrate (6), craft paper or the like may be used as a protective material (7) on the lower surface of the heat insulating material (5), if necessary. Additionally, a finishing material (8) is applied to the top surface of the panel board (6).
). As for the finishing material (8), any floor finishing material such as various carpets and vinyl cloths can be used, but this reduces the heating effect of the steel plate (1) via the hot water pipe (3). Materials that have a strong heat insulating effect and that cause pressure should not be used from the perspective of heating effects.Also, since the skin of the feet and other areas will come into direct contact with the material during use, it is best to use a material that satisfies the tactile sensation of a single person. .

FIG. 1 is an example showing the entire device, and FIG. 3 is a diagrammatic representation of a model case in which the device is installed in each home. This will be explained in detail below. First, referring to FIG. 1, hot water heated by a water heater (9) is circulated through a pipe (11), which is a piping line, by a circulation pump (lO). At that time, this pipe (11
) is connected to the header pipe (12) of the panel board (6) which is divided into two parts. Header pipe (12)
is composed of a pipe that is split into two parts in the middle, and a hot water supply pipe (3), which is a branch pipe, is connected to one of the split header pipes (12), and the extension line is The pipe is connected to another pipe (12) for supplying hot water. In this way, hot water from the water heater (9) passes through the pipe (11) and passes through the header pipe (
12), passes through the hot water supply pipe (9), is connected to another header pipe (12), and then sequentially circulates within the pipe (11). In this case, to explain the connection between the header pipe (12) and the &7 hot water pipe (3), it is very important when considering a hot water supply cycle in which the flow rate of hot water flowing through the pipe (11) can be smoothly adjusted. be. In other words, the diameter of the hot water supply pipe (3) in the panel is expected to be about 1 (normally about 8 mm), while the diameter of the header pipe (12) is about 13 mm; this difference in diameter is taken into consideration. As can be easily understood by looking at Figure 1, the hot water sent from the water heater (9) is divided into two directions by the header pipe (12). , hot water is supplied correctly in two directions, but at the separation part (I3) provided in the header pipe (12), which is the front of the two, apart from the hot water that goes straight, a part of the water is supplied to the hot water supply pipe (3), which is a branch pipe. It is divided into hot water. The hot water flowing through the hot water pipe (3) is transferred to the other header pipe (
12).

Furthermore, an example of construction relating to the apparatus of the present invention will be explained based on FIG. 3 showing an example of a piping route. Water is supplied to the water heater (9) from a hot water supply section (17). The supplied water is
After heating to the scheduled temperature, the circulation pump (1
0), hot water is supplied through the pipe (11) following the piping route.
Circulate sequentially and regularly. In the case of three-point hot water supply, there is a shower (18), a bath (21), and a washroom (19).
, and the hot water in the hot water pipe (11) is provided to the kitchen sink 20) as needed, but this water heater (9) -> shower (18) - bath (21) - washroom (19) - sink 20)→A floor heating panel is connected to the water heater (9) to utilize the heat released from the hot water in the pipe (11) on the hot water supply line. In the example shown in Figure 3, in addition to connecting two panels (26) to the hallway (22), there is also a hot water supply located under the floor near the washroom (23), gas stand (25), and sink (24). This shows an example in which a panel (26) is connected to a pipe (1, j), which is a line. In this way, in the present invention, any number of pipes (
