Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tatami floor heating device for easily heating the floor of a Japanese-style room where tatami mats are laid.

[0002]

2. Description of the Related Art There are various devices for heating a room, such as a stove, a warm air heater, and an air conditioner. However, it is not easy to raise the temperature near the floor, let alone the floor, with these conventional heating devices. There are many complaints that my feet are cold even if the room is warm. This is because the temperature near the ceiling rises due to convection, while the temperature near the floor becomes extremely low.
Circulating the air throughout the room with an air conditioner or a hot air heater will alleviate the problem, but it cannot warm the floor.

For this reason, recently, since it is possible to prevent the feet from being cold by heating the floor itself, many homes are often equipped with this floor heating equipment. FIG. 5 is a schematic view showing a conventional floor heating apparatus. A pipe is provided below the floor material 1, and the liquid heated by a boiler is circulated in the pipe to warm the floor material.
The pipes are laid on a panel 2 of a predetermined size, and the required number of panels 2, 2, ... Are laid, and the pipe 3 is a boiler 4
Is led to.

A liquid is filled in the pipe 3, and the liquid circulates when it is heated to a high temperature by the boiler 4. Therefore, the pipe 3 connected to the panel 2 becomes hot, and this heat heats the floor material 1. Panel 2 with pipe 3 is laid on floor base plywood 5, and floor base plywood 5
A heat insulating material 6 is provided under the structure to prevent heat from escaping under the floor.

As described above, in the case of a Western-style room on which the flooring 1 is laid, floor heating can be configured by arranging the pipe 3 under the flooring 1. Underfloor heating is not easy. That is, since a tatami mat made of straw or a foam plate is a high-performance heat insulating material, even if a pipe is installed under the tatami mat, the upper surface of the tatami mat cannot be warmed. That is, it is impossible to perform tatami floor heating in a Japanese-style room with the same structure as a conventional Western-style room.

[0006]

As described above, the conventional floor heating system cannot be applied as it is to Japan where tatami mats are laid. The problem to be solved by the present invention is this problem, and provides a tatami floor heating device for a Japanese-style room.

[0007]

The tatami floor heating device for a Japanese-style room according to the present invention is constructed so that the surface of the tatami mat can be warmed, and the pipe is laid on the floor base material and the liquid heated in the pipe is used. Flowing warms the pipe and transfers this heat to the tatami surface. On the back side of the tatami mat, there is formed a groove into which a pipe is fitted, and along this groove, holes are formed at appropriate intervals to reach the tatami surface.

A heat transfer member having excellent heat conductivity is fitted in the hole, the lower end of the heat transfer member abuts a pipe piped to the floor base material, and the upper end reaches the tatami floor surface. Therefore, the heat of the pipe can reach the tatami mat surface via the heat transfer member and heat the tatami mat. Here, the heat insulating material is provided so that the heat of the pipe does not escape to the underfloor side, but these structures can be configured in the same manner as the conventional one. Of course, other structures may be used.

In the present invention, the heat source on the floor base material is not limited to the pipe through which the heated liquid flows, and an electric heating sheet can be laid. The electric heating sheet is a thin sheet around which a heating wire is stretched, a tatami mat is laid on the electric heating sheet, and the surface of the tatami mat is warmed through a heat transfer member fitted in a hole formed in the tatami mat. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
