Description

TECHNICAL FIELD The present invention relates to an electric floor heating device, and particularly to a floor heating suitable for floor heating of a large exercise facility having a floor with a floating floor structure such as a gymnasium. Regarding the device.

(B) Conventional Technology Recently, an electric floor heating device has been devised in which a heater unit that generates heat by electricity is arranged between floor joists of a floating floor structure. As shown in FIG. 5, the device is such that the heater unit 22 has a joist member between the joist members 21 and 21 arranged orthogonally on the pulling bar 23 drawn at a predetermined distance from the foundation. Supported by the receiving material 25 fixed to 21, the joists
It is arranged so as to be in close contact with a floor material 26 attached on top of 21. The heater unit 22 includes, as shown in detail in FIGS. 6A and 6B, a sheet heating element 27 that generates heat by electricity and a heat insulating material that covers the back surface of the sheet heating element 27.
The sheet heating element 27 and the heat insulating material 29 are enclosed in upper and lower cases 30a and 30b to form a flat plate shape.

(C) Problems to be Solved by the Invention By the way, the heater unit 22 having the above-mentioned integral structure is used.
The thickness of the heater unit is limited because the heater unit is placed on the joist 21 with the receiving member 25. Therefore, the thickness of the heat insulating material 29 is also limited to a predetermined amount. Therefore, the heater unit 22 described above can obtain a sufficient heating effect when used in a general household house, but when used in a large building such as a gymnasium that requires a large amount of heat generation, the heater unit 22 passes through the heat insulating material 29 and moves downward. The heat escapes from the inside, and it is not possible to obtain a sufficient heating effect.

In addition, the floor of the floating floor structure is normally bent and displaced when it receives an impact on the floor material 26, but especially on the exercise function, when the floor of an exercise facility such as a gymnasium that requires appropriate elasticity receives an impact,
It is set to produce a large amount of bending. Then, when the floor is bent and displaced, a gap is provided between the upper surface of the heater unit 22 and the back surface of the floor material 26, which are supported by the receiving material 25 of the joist material 21 and are closely attached to the back surface of the floor material 26. Is completed,
There is a drawback that air convection occurs between the heater unit 22 and the floor material 26, and heat conduction from the heater unit 22 to the floor material 26 is hindered, resulting in deterioration of floor heating efficiency.

Therefore, the present invention provides a structure in which it is easy to configure the heat insulating material to a required thickness, and the heater unit does not easily follow the displacement of the floor material to form a gap, thereby solving the above-mentioned problems. The purpose is to do.
