[Industrial applications]

 The present invention relates to a hot water heating mat which is placed on a floor of a house, for example, a carpet is laid on the floor, and the floor is heated by hot water from a heat source device such as a stove or a water heater.

[0002]

[Prior art]

 As a hot water heating mat as described above, a fitting that has an open part on the upper surface for fitting a cylindrical hot water pipe formed of synthetic rubber into a flexible mat body made of foam synthetic resin For example, Japanese Utility Model Laid-Open No. 61-198885 discloses that a fitting groove is provided in a meandering manner, and a hot water supply pipe is fitted into the fitting groove and attached. The mat body of such a hot water heating mat is usually rectangular.

[0003]

[Problems to be solved by the device]

 Since the conventional hot water heating mat has a rectangular shape, it is not possible to know where the stove or water heater as a heat source device is installed in the room during construction. We had to prepare multiple types of hot water heating mats with different positions of both ends of the hot water supply pipe so that it could be used at any position.

Further, when it is desired to rotate the hot water heating mat by 90 degrees in association with the change of the room, it is often the case that the hot water heating mat cannot be rotated by 90 degrees. In such a case, each pipe between the water heater and the inlet part of the hot water pipe for introducing hot water from the water heater of the hot water heating mat, the outlet part of the hot water pipe for returning hot water to the water heater, and the water heater There was the inconvenience that it was not possible to easily respond to the remodeling of the room because it was necessary to re-pipe.

The present invention has been made in order to eliminate the above-described inconvenience, and when performing construction or changing the room, the heat source device can be installed without being bothered by the installation position of the heat source device. The present invention provides a hot water heating mat that can be rotated by 180 degrees and / or simply by changing the mounting position of the short-circuit pipe without having to re-pipe each pipe.

[0006]

[Means for Solving the Problems]

 This invention is a mat for hot water heating in which a hot water supply pipe is laid on the mat body and hot water is flowed from one end to the other end of the hot water supply pipe. The mat main body is rectangular and two hot water supply pipes are paired. One end of the pair of hot water pipes is placed in one of the adjacent corners of the mat body, and the other end of the pair of hot water pipes is placed in the other of the adjacent corners of the mat body. One end portion of the hot water supply pipe is connected with a detachable short-circuit pipe.

[0007]

[Action]

 Since the hot water heating mat according to the present invention is configured as described above, it occupies the same area at the same position even when rotated by 180 degrees. However, when the hot water heating mat is rotated 180 degrees, the positions of the other end portions of the pair of hot water supply pipes, that is, the introduction port portion and the discharge port portion are changed by 180 degrees. Also, by changing the mounting position of the short-circuit tube, the positions of the inlet port and the outlet port are changed by 90 degrees.
