Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a flexible floor heating panel using a heating fluid such as hot water as a heating medium.

BACKGROUND OF THE INVENTION In general, a soft floor heating panel that uses a heating fluid such as hot water as a heat medium has a plurality of piping grooves on a base sheet 10 made of thermoplastic resin foam that serves as a heat insulating layer of the panel, as shown in FIG. 11 are provided in parallel, a plurality of conduits 12 for circulating a heat medium are laid in this piping groove 11, and the plurality of conduits 12 are gathered within the panel, and a piping joint is used to connect with the piping to the panel. A header 13 having a header 14 was attached to the side of the base sheet I-10. This piping joint 14 is housed within the thickness of the panel and is prevented from protruding from the front and back surfaces of the panel. In the figure, 15 indicates a surface material, and 16 indicates a floorboard.

Problems to be Solved by the Invention However, in the flexible floor heating panel having the configuration described in item 1, the piping joint part 14 of the hengoo 13 is housed on the side of the panel and within the thickness, and the piping up to the panel is placed in the underfloor tube. When installing, the piping must be placed under the floor from outside the panel and connected to the piping under the floor.

If you drop the piping below the floor outside the panel as described above,
Depending on the size of the room where the panel is installed, there may be little space between the edge of the panel and the wall, making it impossible to sink it. Furthermore, if the foundation of the building is under the floor, it will not be possible to penetrate the hole to the bottom of the floor, making it impossible to install panels.

Furthermore, as synthetic resin pipes are increasingly being used for piping these days, the synthetic resin pipes cannot be bent at right angles when making through-holes under the floor, so the through-holes must be diagonal, making drilling difficult. In addition, wasted space is required due to the through-hole space under the floor, and the heat radiation area of the floor heating panel cannot be ensured, making it impossible to provide a comfortable space due to insufficient heat radiation ability.

The present invention solves the above-mentioned conventional problems, and its purpose is to eliminate wasted space in a room where floor heating is intended, effectively secure the heat dissipation area of floor heating, and provide a comfortable heated space. There is a particular thing.

Means for Solving the Problems In order to achieve the above object, the present invention provides piping grooves on a base sheet and lays a plurality of conduits for circulating a heat medium through the piping grooves, and the conduits are arranged in parallel. A number of conduits are converged in a part of the header at the outlet/inlet section within the panel. - A pipe connection joint protrudes from the back side of a part of the ladder so that it can be connected to the pipes under the floor within the panel.

Effect of the present invention: Due to the configuration described in item 1, the piping connection joints of a part of the header protrude from the back of the panel, so it is possible to connect to the piping under the floor within the panel, eliminating the need for space between the panel and the surrounding wall. , the installation area for floor heating panels is large, providing a comfortable heated space. In addition, there is no need to diagonally drill through holes for piping under the floor, making it easier to work through holes for piping.
The space between the wall and the panel is also unnecessary.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3. The base sheet 1, which is a heat insulating layer, is made of thermoplastic resin foam, and on the surface side of the base sheet 1, three to five piping grooves 2 are provided in parallel with each other and in a meandering shape. be. The illustrated case is an embodiment in which three piping grooves 2 are provided, and each piping groove 3 gathers at a portion where both ends face the peripheral edge 3 of the base material sheet 1-1. A header 5 is provided. A conduit 6 through which a heat medium such as hot water is separately distributed is laid in each piping groove 2, and the starting and terminal ends of these conduits 6 are connected by a header 5 to an inlet port 5a and a return port. 5b respectively, while profiteering sea 1-1
A covering material 7 is adhered to the surface side of.

In the above configuration, the thermoplastic resin foam that is the material of the base sheet 1 has an expansion ratio of 10 to 40 times and a thickness of 3 times, for example.
A cross-linked foam of low density polyethylene with a thickness of ~20 mm is used. The conduit 6 is made of a crosslinked low-density polyethylene that matches the thickness of the base sheet 1-1. As the covering material 7, a thermoplastic resin film, its foam, woven fabric, non-woven fabric, aluminum foil with good thermal conductivity, etc. are used.

The hender 5 brings together the starting end and the ending end of the conduit 6 and connects the inlet port 5a and the return port 5b, respectively. The introduction port 5a and the return port 5b protrude toward the back side of the panel. Note that 8 in the figure represents the surface material and 9 represents the floorboard.

According to the above configuration, when connecting to under-floor piping, the piping through hole 8 can be formed directly under the inlet port 5a and the return port 5a of the belly button 5 in the panel. In addition, there is no need for space around the panels between them and the walls, eliminating wasted space, making it possible to secure a large area for installing floor heating panels, and creating a comfortable floor heating space.

Effects of the Invention In the present invention, as described above, the introduction port and the return port of the header 5 in the panel are made to protrude to the back side of the panel.
When connecting to under-floor piping, there is no need for a space between the wall and panel for the piping to go under the floor. Additionally, there is no need to diagonally drill through-holes under the floor, making the drilling work easier. Furthermore, by eliminating wasted space as described above, a larger area for installing floor heating panels can be secured, and the amount of heat dissipated can be increased, providing a comfortable heated space.
