Description

[Detailed description of the invention] This invention relates to an improvement of a rubber mat equipped with a large number of small hot water pipes for transferring hot water for room heating in cold regions.The improvement is that it provides breathability on both the front and back sides of the mat body. It is oriented toward that.

In regions such as Hokkaido, where winters are extremely cold, in order to increase the efficiency of indoor heating, it is necessary not only to use ordinary heating devices such as various stoves and heaters, but also to install heating mats or jutans on the floor of the room. The system uses a method that heats the room from above the floor level. There are two types of such heating mats: one that generates electricity using electricity, and one that transports hot water (particularly hot water that has been heat-exchanged with exhaust heat from a stove), and the present invention belongs to the latter category. According to Figure 1,
To give an overview of indoor heating systems including this mat and point out the shortcomings, 1 is a hot water transfer rubber mat made of heat-resistant rubber, and this mat has a plurality of hot water pipes 11 placed side by side on the mat main body 10 with both ends open. At the same time, rib strips 12 are arranged in parallel between adjacent hot water pipes 11-11, and these hot water pipes 11 and rib strips 12 are integrally molded with the mat main body 10. The procedure is as shown in Figure 1, where multiple mats 1 (two mats 1 in the figure) are placed adjacent to each other.
1'] is usually laid on the tatami mats 3, and the water pipe 4 is also laid on the tatami mat 3. [In the figure, the water pipe 4 is connected to the top and bottom only on the right side of the boundary line a] Connect the connection plugs (not shown) of the connecting pipe 5 and the drain pipe 6 to the openings 1 at both ends of the hot water pipes 11...
11 . By doing this, the hot water flows from the water pipe 4 through the hot water pipe 11 of the mat 1 on the right in the figure to the connecting pipe 5, and then passes through the hot water pipe 11 of the mat 1' on the left to the drain pipe 6. As a result, the room is heated from the floor (tatami mat) at the lowest level, and the warm air is convected throughout the entire height range of the room, resulting in efficient room heating. The above-mentioned hot water is usually generated by a heat exchanger (not shown) connected to the indoor part of the chimney of the stove, and this is subjected to back pressure from a water pump (not shown) to generate the hot water pipe 11.
... (see arrow direction in the figure). Note that the rib strips 12 are provided for reinforcement.

Now, in the above system, the rubber mat 1 is a blind board in the thickness direction, so if it is laid on the tatami 3 and the heating is repeatedly started and stopped, there will be a gap between the tatami 3 side and the front side of the mat 1. Since the air permeability is blocked, there is a serious problem in that there is a lot of moisture on the back side of the mat 1, that is, on the surface of the tatami mat 3, which wets the tatami mat 3 and eventually causes it to rot. The degree of this increases as the temperature difference between the room temperature and the area under the tatami increases.
Naturally, the higher the frequency of ON and OFF, the more noticeable it becomes.

The present invention has been made in view of the above, and is constructed by providing multiple ventilation holes 2 that penetrate the thickness of the mat main body 10 between the hot water pipes 11 and the rib strips 12 and/or between the rib strips 12. In the figure, the vent hole 2 is shown as an example in which it has an oval shape and is provided only between the hot water pipe 11... and the rib strip 12..., but the shape of the vent hole 2 may be circular, rectangular, etc. Of course, it is possible to select as appropriate, such as making it polygonal or any other arbitrary shape, or providing the installation location not only between the hot water pipes 11 but also between the ribs 12, or only between the ribs 12. It is a place where it can be done.

Since the present invention has the above-mentioned configuration, air permeability is maintained between the tatami 3 side and the surface side of the mat 1 by the ventilation holes 2, so as mentioned above, there is a lot of moisture on the tatami 3 side. This prevents the evaporation of tatami mats into the room and has the effect of eliminating the damage and rot of tatami mats, which have been a concern up until now.
