Description

[Detailed description of the invention] This invention relates to a floor heating panel that heats a room by circulating hot water through hot water pipes provided on a heat sink.

As shown in FIGS. 1 to 4, a conventional floor heating panel has a hot water pipe 1 through which hot water flows, a protective sheet 3 and a side wall 2a erected around a flat surface to form a box shape, and a floor heating panel that is shaped like a box. The heat sink 2 is closely fixed to the heat sink 2 provided with the bottom surface 3C formed by curling inward to increase the contact area, and the heat insulating material 4 is injected between the heat sink 2 and the bottom paper 5. .

One pipe end 8 and the other pipe end 9 of the hot water pipe 1 are provided at two diagonal locations to form a connection part and form a floor panel 6.

Although not shown, a floor panel 7 has a connecting portion formed in a symmetrical position to the floor panel 6.

The floor panels 6 and 7 configured as described above are constructed by combining six floor panels and eight floor panels as shown in FIGS. Union joint the pipe end 9.

A hot water pipe 1 is formed in series by brazing or jointing using a connector 10 such as a sleeve using a rubber hose or an O-ring.

The thus constructed floor panel 6.7 uses either the pipe end 8 or the pipe end 9 as the hot water inlet part 11 and the other as the outlet part 12, and allows hot water to flow through the floor panel 6.7. Hot water flows through the hot water pipe 1 piped to 7, and the thermal energy of the hot water is conducted to the heat sink 2 via the protective sheet 3 etc., raising the temperature of the entire floor surface and increasing the temperature inside the room. heating.

Although heating is performed in this way, the heat dissipation plate 2 has side walls 2a erected around the flat surface, and the bottom surface is formed by curling, which requires many processing steps and has the disadvantage of being expensive. Ta.

This invention was made in view of the above-mentioned drawbacks, and the purpose is to provide a floor heating panel that can be manufactured at low cost by eliminating the bottom surface and eliminating the curling process.

An embodiment of this invention will be described below with reference to FIGS. 5 to 11. In the figures, reference numerals 20 and 21 denote a floor panel A and a floor panel B, in which side walls 40 are erected around a flat surface and are shaped like a flat box. The formed heat sink A22 and heat sink B23 are connected by a hinge 24 so as to be bendable.

Reference numeral 25 denotes a hot water pipe provided in series across the heat sink A22 and the heat sink B23, and is made of a flexible plastic pipe.

26 is a protective sheet that makes the hot water pipe meander and is closely fixed to the heat sink plate 22, 23; 27 is a pipe holder that supports both sides of the bent portion of the hot water pipe 25; and 28 and 29 are attached to the two corners of the heat sink plate A22. An outgoing pipe and a returning pipe are formed by intersecting each other in the middle, and 31 is a T-shaped pipe provided at the inlet of the outgoing pipe and the outlet of the returning pipe, and 3
2 is a single-shaped pipe provided at the outlet of the outgoing pipe 28 and the inlet of the returning pipe, and 33 is the outgoing pipe 28. Return pipe 29 and hot water pipe 2
5 is a hose band for fixing the fitting portion of the T-shaped tube 31 and the ■-shaped tube 32, and 34 is the heat sink A22 and the heat sink B.
Protective tubes are diagonally provided at the connecting portions of the hot water pipes 23, respectively, and are provided so as to collect and pass through the reciprocating pipes of the hot water pipes 25, which are provided in a meandering manner.

Reference numeral 35 denotes a protective member provided in the penetrating portion of the protective tube so as to wrap around the hot water pipe 25, which is slightly longer than the protective tube, 36 is a cap that closes both ends of the protective tube 34, and 37 is a heat insulating material. A predetermined space is formed between the flat surface of the heat dissipation plate so as to cover the radiator plate, etc., and the end of the upper membrane side wall 40 is provided in contact with the bottom plate 38 formed of felt or the like. Made of urethane foam.

The floor heating panel configured as described above is installed and used on the floor by connecting it with a connector 39 as shown in FIG. 11, depending on the size of the room.

In this way, hot water is supplied through the outgoing pipe 28, circulated through the hot water pipe 25 from the T-shaped pipe 31, and returned to the returning pipe 29, thereby allowing the heat sink A22. The heat sink B23 is heated and heats the room from the floor surface.

Floor panel A20 used in this way. Since the floor panel B21 is connected by the hinge 24, it can be bent and does not take up much space.

Furthermore, since the heat dissipation plates 22 and 23 are box-shaped with side walls 40 erected around the plane, curling processing is not required as in the conventional case, and the cost becomes low.

Note that the ends of the side walls 40 of the heat dissipation plate are bonded to the bottom plate 38 by foaming the heat insulating material 37, and since the bottom plate 38 is made of elastic felt, the adhesion is reliable. This will not damage the floor surface.

As explained above, according to this invention, a predetermined space is created between a heat sink formed in a box shape with side walls erected around a flat surface, hot water pipes provided on the heat sink, and the flat surface of the heat sink. A bottom plate made of an elastic member is provided in contact with the cut end surface of the side wall so as to be formed, and a heat insulating material made of urethane foam is provided in the predetermined space.
Unlike the conventional method, curling is not required at the end of the heat sink, making the heat sink inexpensive, and the heat sink and the bottom plate are bonded reliably.
