[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft floor heating mat improved so that it can be easily rewound to a small diameter.

[0002]

2. Description of the Related Art In a flexible soft floor heating mat using a heating fluid such as hot water as a heat medium, piping grooves are provided on a base sheet made of a thermoplastic resin foam, which serves as a heat insulating layer of the mat.
A pipe having a structure in which a conduit for circulating a heat medium is laid in the pipe groove and a coating material is applied to the front side of the base sheet, and a rubber plate is laminated and bonded to the back side of the base sheet is known. (See Japanese Utility Model Laid-Open No. 2-55016).

[0003]

The above-mentioned known soft floor heating mat has a reinforcing effect on the base sheet because a rubber plate is laminated and adhered to the back surface of the base sheet. This has the effect of suppressing running water noise and impact noise. However, when the covering material adhered to the surface side of the base material sheet is an aluminum foil, the aluminum foil and the rubber plate are easily adhered to each other, the slip at the time of winding the mat is poor, and it is difficult to rewind to a small diameter. is there.

[0004] As a result, the mat is not well entrained,
There was a problem that it was unduly bulky and inconvenient for storage and transportation. This is the same even when an ordinary resin film is laminated and adhered to the back surface of the mat, and an improvement measure has been desired. The purpose of the present invention is to solve such a problem. The purpose of the present invention is to improve the relative slipperiness between the aluminum foil, which is the surface coating layer of the mat, and the back side of the mat, and to make small diameter rewinding easy. An object of the present invention is to provide a floor heating mat.

[0005]

In order to achieve the above object, a soft floor heating mat according to the present invention is provided with a pipe groove on a base sheet made of a thermoplastic resin foam which is a heat insulating layer, A conduit through which the heat medium flows is laid in the pipe groove, and the starting end of the conduit is connected to the inlet of the header, and the end is connected to the return opening of the header. In the soft floor heating mat having the above structure, a thermoplastic resin film whose outer surface is roughened is laminated and adhered to the back surface of the base sheet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below with reference to the accompanying drawings. A base sheet 1 which is a heat insulating layer of the mat is formed of a thermoplastic resin foam, and a pipe groove 2 is provided on a surface side of the base sheet 1. In the case shown, the pipe groove 2 is 3
These pipe grooves 2 are provided in a meandering manner in parallel with each other, and each of the pipe grooves 2 is assembled at a portion where both ends face the peripheral edge 1 a of the base sheet 1. .

A header 3 is mounted on the base material sheet 1 corresponding to the gathering portion, and conduits 4 for circulating a heat medium such as hot water are laid in each piping groove 2. And the end are connected to the inlet 3a and the return 3b of the header 3, respectively. An aluminum foil 5 is adhered to the front side of the base sheet 1, and a thermoplastic resin film 6 having a roughened outer surface 6 a is laminated and adhered to the back side of the base sheet 1, so that soft floor heating is performed. Make up the mat.

In the above construction, the thermoplastic resin foam as a material of the base sheet 1 has a bleeding magnification of, for example, 10 to 4
It is preferable to use a low-density polyethylene cross-linked foam having a thickness of 0 to 3 to 20 mm. The conduit 4 has an outer diameter of 8 mm when the base sheet 1 has a thickness of 10 mm, for example.
It is preferable to use a thermoplastic resin tube having an inner diameter of 5 mm, particularly a low-density crosslinked polyethylene tube. For the thermoplastic resin film 6, for example, an embossed film made of low-density polyethylene having a thickness of 50 microns is used.

[0009]

The present invention is as described above. When the mat is wound, a thermoplastic resin film whose outer surface is roughened is laminated and adhered to the back surface of the mat in contact with the aluminum foil which is the surface layer. Therefore, the inconvenience that the two layers are in close contact with each other and the slippage is poor is completely eliminated, and the rewinding to a small diameter can be easily performed.

The presence of the thermoplastic resin film is effective in preventing the substrate sheet formed of the foam from being easily damaged, and has a function of imparting moisture-proof properties to the substrate sheet side. Therefore, its practical value is extremely large.
