The heating element 4 and the heat insulating plate 5 are further stacked on the heating element 4, and the sheet heating element 4 and the heat insulating plate 5 are housed in the frame body 2 to form a rectangular panel as a whole. The sheet heating element 4 is attached to the back surface (top surface) of the gypsum board 3 with a double-sided adhesive tape.

The gypsum board 3 serves as a ceiling board for a room, and a ready-made plaster board provided as a ceiling gypsum board can be used. The surface (lower surface) of this gypsum board 3 is coated with far-infrared radiation paint containing ceramics.

As shown in FIGS. 5 and 6, the sheet heating element 4 has a strip shape made of copper foil formed on both side edges of both sides of the conductive resin layer 7 uniformly impregnated with the carbon element. Along with the electrode 8, it is covered with a hard heat resistant insulating resin film 9/10. A power cord 11 is connected to one end of the electrode 8 for power supply as follows.

In FIG. 7, the solder 12 is attached to one end of the electrode 8.
Of the mold resin 14 in which the core wire of the power cord 11 is connected and the connecting portion is filled in the circular cover 13.
Insulated.

Thermostats 15 and 16 having a built-in thermal fuse are connected to the power cord 11, and these thermostats 15 and 16 are attached to the surface of the insulating resin film 9 by a double-sided adhesive tape, and the power cord 11 is fixed. The tape 17 is fixed to the surface of the insulating resin film 9 at required points. The power cord 11 drawn out from the sheet heating element 4 uses the sheet heating elements 4 of the two ceiling radiant heating panels 1 connected in parallel when the two ceiling radiant heating panels 1 are used in parallel as one unit. It is branched and connected as possible.

When the thermostats 15 and 16 rise above a certain set temperature T1, the energization of the conductive resin layer 7 is cut off, and the thermal fuses built in these cut off when the temperature rises above T2 which is higher than T1. It cannot be energized.

Ceiling radiant heating panel 1 having such a structure
The plurality of them are arranged side by side in the field of the ceiling of the room and supported to form a ceiling surface as a whole. Attach and finish the ceiling surface.

The electrical system diagram of FIG. 8 shows the electrical wiring of a large number of ceiling radiant heat heating panels 1 after installation on the ceiling. A large number of ceiling radiant heating panels 1 are divided into groups, and in each group the planar heating elements 4 are sequentially wired and connected by a power cord 11, and a power cable 21 drawn from the ceiling radiant heating panel 1 at one end of each group. Is connected to the relay terminal 23 of the relay terminal box 22, the relay terminal 23 is connected to the distribution board 24 by wiring, and the printed circuit board 25 in the relay terminal box 22 is connected to the centralized controller 26. In order to detect the temperature of the ceiling surface by the ceiling radiant heat heating panel 1, for example, a temperature sensor (not shown) is installed outside any one of the ceiling radiant heat heating panels 1, and the temperature sensor and the printed circuit board 25 are used as sensors. It connects with the cable 27 for.

With such a wiring structure, the centralized controller 26 can centrally perform the power supply control and temperature control to all the ceiling radiant heat heating panels 1. The centralized controller 26 and the relay terminal box 22 may be integrated.

In the ceiling radiant heat heating panel 1 supplied with electricity, when the sheet heating element 4 generates heat and the gypsum board 3 is heated, far infrared rays are radiated from the gypsum board 3 and at the same time, applied to the surface thereof. Far-infrared radiation is also emitted from the existing far-infrared radiation paint to increase the radiation amount, and the far-infrared radiation is evenly radiated by compensating for the radiation unevenness of the gypsum board 3.
Since far-infrared radiation paint contains ceramics, more far-infrared radiation can be emitted.

The sheet heating element 4 comprises a conductive resin layer 7 uniformly impregnated with a carbon element, and both sides of which are covered with strip-shaped electrodes 8 of copper foil and hard heat resistant insulating resin films 9 and 10. Therefore, the surface temperature rises quickly, the temperature distribution on the surface is uniform, and far-infrared radiation without unevenness is obtained, and the power consumption is low. Moreover,
Since it is thin, the depth of the accommodation space by the frame body 2 is sufficient to accommodate the heat insulating plate 5 made of glass wool, and the depth for accommodating the planar heating element 4 is unnecessary.

Therefore, even if the temperature of heat generated by the sheet heating element 4 is low, a large amount of far infrared rays are evenly radiated from the ceiling surface by the ceiling radiant heat heating panel 1, so that the entire room can be radiated with far infrared rays with less power consumption. Can be heated comfortably.
Moreover, the overall thickness of the ceiling radiant heat heating panel 1 can be reduced and the weight thereof can be reduced.

Each ceiling radiant heat heating panel 1 is provided with thermostats 15 and 16 having a built-in temperature fuse, that is, an excessive temperature rise preventing means is individually provided for each panel 1, and the central control controller 2 is further provided.
Since the temperature is centrally controlled by 6, safety is extremely high.

The ceiling radiant heat heating panel 1 may be installed on the ceiling with the above-described one-piece structure, but as described above, two pieces are integrated in parallel to form one unit, and the unit is installed on the ceiling. You may.

[0022]

As described above, according to the present invention, as a heating plate for heating a gypsum boat to radiate far infrared rays, both surfaces of a conductive resin layer impregnated with a carbon element are covered with insulating resin films. Since the sheet heating element is used, the surface temperature rises quickly, far-infrared radiation with uniform temperature distribution on the surface is obtained, and the power consumption is low. Moreover, since it is thin, the overall thickness of the ceiling radiant heat heating panel 1 can be reduced and the weight thereof can be reduced.

According to the second aspect of the invention, it is possible to safely connect the sheet heating element and the power cord.
