Description

[Detailed description of the invention] This invention relates to a floor heating system that heats indoor spaces by guiding hot water to pipes placed under the floor.The purpose of the invention is to facilitate the placement of the pipes under the floor. At the same time, it is an object of the present invention to provide a floor heating device that fully utilizes heat from hot water.

Conventional systems of this type simply flow hot water through pipes placed below the floor, so heat is not only dissipated (heat conduction) to the floor, but also below the floor. The drawback was that the heat from the hot water could not be used sufficiently for indoor heating.

The present invention seeks to eliminate the above drawbacks.

The present invention will be explained below with reference to the drawings.

An embodiment of the present invention is shown in FIGS. 1 to 4.

Reference numeral 1 denotes a floor panel disposed below the floor surface into which pipes 2 for flowing hot water are incorporated, and the pipes 2 are arranged in parallel directly below a metal plate 22.

The surface of this floor panel 1 is formed of a floor surface material (plywood, carpet, etc.) 20 and is lined with a heat insulating material 21.

The pipe 3 is fitted and supported between opposing support arms 24 formed by punching a metal plate 22 of aluminum, copper, or the like with good thermal conductivity downward in a double-opening pattern. It spreads below.

An air tube 3 through which air flows is inserted through each of the pipes 2 at the inner bottom.

The pipe 2 and the air pipe 3 are arranged closely together at the bottom of the pipe 2, and the heat dissipated below the floor surface of the hot water is transferred to the air pipe 3.
It is sufficient that the hot water is blocked by the air flowing inside and that heat is exchanged between the hot water and the air.

Inserting the air tube 3 through the bottom of the pipe 2 as in this embodiment is one way to improve the efficiency of heat exchange.

As another method, as shown in FIG. 5, the pipe 2 may be partitioned into upper and lower parts, with the upper part being a hot water flow path and the lower part being an air pipe 3 through which air flows.

Each air pipe 3 is arranged from an inlet 4 on the top surface of one end of the floor panel 1 to an outlet 5 on the top surface of the other end, and the suction port 4 of each air pipe 3 is equipped with a fan 6. ing.

9 is a power source for the fan 6, which rotates when a switch (not shown) is turned on.

The pipes 2 arranged in parallel are connected by an auxiliary pipe 2' and continue from a hot water hole lower opened at one end to a hot water outlet 8 opened at the other end.

When hot water flows into the pipe 2 from the lower hot water hole, the hot water radiates heat to the floor surface and heats the room through the floor surface.

This heating alone cannot quickly heat the room, but when the fan 6 is turned on, the fan 6 sucks the indoor air into the air pipe 3, and the flowing air causes hot water to flow under the floor. On the other hand, the heat of the hot water is quickly transmitted from the surrounding area to the entire surface of the metal plate 22 by the supporter 24 that supports the pipe 2, uniform floor heating is performed, and the air flowing through the air pipe is tube 3
Since the air exchanges heat with hot water inside the room and is quickly blown out indoors from the outlet 5, the blown air heats the room extremely quickly.

Fig. 6 shows a different embodiment of the present invention, in which a pipe 2 and an air pipe 3 inserted through the pipe 2 are folded under a carpet 10 forming a floor surface so that they are arranged side by side. Since the air pipe 3 is made of one continuous pipe body, only one fan 6 is required for sucking and discharging the air.

This pipe 2 is also fitted and supported between opposing supports 24 formed by punching out a metal plate 22 downward in a double-sided pattern.

In this case, since the air pipe 3 has only one outlet 5, the outlet 5 is provided with a nozzle 12 having air holes 11 arranged side by side.

Even in this embodiment, when hot water is flowed through the pipe 2 and the fan 6 is turned on, the air flowing through the air pipe 3 prevents the hot water from dissipating below the floor surface, and the heat of the hot water flowing through the pipe 2 is reduced. The whole surface of the metal plate 22 is used for floor heating from the periphery of the pipe 2 through the supporter 24, and the indoor air is immediately directly heated by hot water and discharged indoors, quickly heating the indoor room. It is.

As mentioned above, in the present invention, the radiation of the heat of the hot water flowing through the pipe placed below the floor to the bottom of the floor is cut off by the air flowing through the air pipe placed closely at the bottom of the pipe.
The heat of the hot water is quickly conducted to the metal plate under the floor via the supports that support the pipes, uniformly heating the floor, and heat is exchanged with the air flowing through the air pipes, immediately warming the room. The effectiveness of its use is extremely good.

Note that heating using a fan is performed only when necessary.
