Thermostats 15 and 16 each 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 with a double-sided adhesive tape. It is fixed to the surface of the insulating resin film 9 at a required position. When the power cord 11 drawn from the sheet heating element 4 is used as one unit by arranging two ceiling radiation heating panels 1 in parallel, the sheet heating elements 4 of the two ceiling radiation heating panels 1 are connected in parallel. Branch connections are made so that they can be made.
[0012]
The thermostats 15 and 16 cut off the power supply to the conductive resin layer 7 when the temperature rises above a certain set temperature T1, and the temperature fuses built therein are blown when the temperature rises above T2 higher than T1. I do.
[0013]
The heat insulating plate 5 is formed by molding glass wool into a plate shape. An aluminum foil 18 is attached to the upper surface of the heat insulating plate 5 for reflection of far-infrared rays, heat insulation of radiant heat, waterproofing (prevention of leakage due to rain leakage), and the like. Further, a waterproof tape 19 is stuck on the aluminum foil 18 from the upper surfaces of the frame members 2a, 2b, 2c, 2d on the four sides of the frame body 2.
[0014]
The ceiling radiant heating panel 1 having such a structure is constituted by arranging a large number of such panels side by side on a ceiling of a room or the like to form a ceiling surface as a whole, and the entire ceiling surface, that is, a far-infrared radiation paint is applied. The cloth 20 is stuck on the surface of the gypsum board 3 to finish the ceiling surface.
[0015]
The electrical system diagram of FIG. 8 shows the electrical wiring of a large number of ceiling radiant heating panels 1 after installation on the ceiling. A large number of ceiling radiant heating panels 1 are divided into groups, and the planar heating elements 4 are sequentially wired and connected by a power cord 11 in each group, 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, and 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 by wiring. In order to detect the temperature of the ceiling surface by the ceiling radiant heating panel 1, for example, a temperature sensor (not shown) is installed outside one arbitrary ceiling radiant heating panel 1, and the temperature sensor and the printed circuit board 25 are connected to the sensor. Cable 27 for connection.

With such a wiring configuration, power supply control and temperature control to all ceiling radiant heat heating panels 1 can be centrally performed by the central controller 26. The central control controller 26 and the relay terminal box 22 may be integrated.
[0017]
The supplied ceiling radiant heat heating panel 1 emits far-infrared rays from the gypsum board 3 when the gypsum board 3 is heated by the heating of the planar heating element 4 and the far-infrared rays applied to the surface thereof. Far infrared rays are also emitted from the radiant paint to increase the amount of radiation, and the radiation unevenness of the gypsum board 3 is compensated to radiate the far infrared rays evenly. Far-infrared radiation paints can emit more far-infrared rays because they contain ceramics.
[0018]
The planar heating element 4 is formed by covering both surfaces of a conductive resin layer 7 in which carbon elements are uniformly impregnated with a band-shaped electrode 8 made of copper foil and hard heat-resistant insulating resin films 9 and 10. In addition to the rapid rise of the surface temperature, far-infrared radiation with a uniform temperature distribution on the surface and no unevenness can be obtained, and low power consumption. In addition, since it is thin, the depth of the accommodation space by the frame 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.
[0019]
Therefore, even if the heating temperature of the planar heating element 4 is low, a large amount of far-infrared rays are evenly radiated from the ceiling surface by the ceiling radiant heating panel 1, so that the entire room can be comfortably heated by far-infrared radiation heat with low power consumption. Can heat. Further, the overall thickness of the ceiling radiant heating panel 1 can be reduced, and the weight can be reduced.
