Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor heating device, and more specifically, a heat sink made of a steel plate or the like and having a space at the bottom thereof, a hot water pipe provided in the space below the heat sink, and the heat sink. Almost the entire lower space of the board is provided with first and second floor heating panels having a heat insulating material provided to cover the hot water pipe, and the first floor heating panel and the second floor This relates to a floor heating device that is foldable and connects to a heating panel.
The purpose is to eliminate the screws for fixing the connection odor.

This invention will be explained below using FIGS. 1 to 8.

In the figure, 20 and 21 are the first floor heating panel and the second floor heating panel.
24 is the first and second floor heating panel 20
, 21 are foldably connected to form a floor heating system, and the first and second connecting pieces 2 have bent ends.
4A and 24B are rotatably connected by a pin 24C.

22 and 23 are made of a material with good heat conductivity such as a steel plate or an aluminum plate, and are formed into a flat box shape so that a space is formed at the bottom;
Reference numeral 5 denotes a hot water pipe provided in a series across the first heat sink 22 and the second heat sink 23, and is made of a flexible plastic pipe.

Reference numeral 26 denotes a fixing member that is closely fixed to the first and second heat sinks 22 and 23 so that the hot water pipe meanders, and is fixed after the hot water pipe 25 is held by a pipe holder to be described later.

A pipe holder 27 holds both sides of the bending start portion of the hot water pipe 25, and is formed so that the hot water pipe 25 can be attached or detached.

Reference numerals 28 and 29 denote an outgoing pipe and an incoming pipe formed by intersecting each other in the middle with recesses 301 provided at the two corners of the first heat dissipation plate 22, and 31 indicate an inlet of the outgoing pipe and an incoming pipe. 32 is a T-shaped pipe provided at the outlet of the outgoing pipe 28 and the inlet of the returning pipe; 33 is the outgoing pipe 28;
Hose bands 34 fix the joints of the return pipe 29 and the hot water pipe 25 with the T-shaped pipe 31 and the single-shaped pipe 32, respectively, at the connecting parts of the first heat sink 22 and the second heat sink 23. A diagonally installed protective tube is provided to gather the reciprocating pipes of the hot water pipes 25 which are provided in a meandering manner, and to pass through them.

Reference numeral 35 denotes a protection member provided in the penetrating portion of the protection tube so as to wrap around the hot water pipe 25, and 36, a cap that closes both ends of the protection tube 34, and 37, a protection member to cover the hot water pipe, etc. A heat insulating material such as urethane is injected and foamed into the space formed between the first and second heat dissipating plates 22, 23 and the bottom plate 38.

The floor heating device configured as described above is manufactured as follows. That is, the first and second heat sinks 22 are shaped like flat boxes.
, 23, a hot water pipe 25, an outgoing pipe 28, and a returning pipe 29.
After arranging the components of the floor heating system as shown in FIG.
It is located in the lower space of the first heat sink 22, and the second connected odor piece 24B is located in the lower space of the second heat sink 23. After that, after installing the bottom plate 38 so as to close all the lower entrances of the heat sinks 22 and 23, the heat sinks 22 and 23 are closed.
Urethane, which is the material of the heat insulating material 37, is injected into the lower space of the heat sinks 22 and 23 from a predetermined part of the heat sink 23, foamed, and solidified. Although it is useless as a part for connecting the floor heating panel 20 and the second floor heating panel 21, after the urethane foam is injected and solidified, both ends will be buried and fixed in the urethane foam. Therefore, it functions as a component that connects the first and second floor heating panels 20 and 21.

The device according to the invention is thus manufactured.

This device is installed and used on the floor by connecting it with a connection 39 as shown in FIG. 7 depending on the size of the room. In this way, hot water is supplied through the outgoing pipe 28, circulated through the overflow pipe 25 from the T-shaped pipe 31, and returned to the outgoing pipe 29, whereby the first heat sink 22 and the second heat sink 23 are heated. The connected odor 24 is heated by the eighth
Although it is desirable to provide bent portions at both ends as shown in the figure, these bent portions are not necessarily required.

As described above, according to the present invention, since the connecting metal fitting that foldably connects the first floor heating panel and the second floor heating panel is embedded and fixed in the heat insulating material, the connecting metal fitting This eliminates the need for screws for fixing and simplifies the manufacturing process.
