This liquid-powder mixture is charged into a prepared moldbase to a height about half that of the panel that is desired to be manufactured, and thus a lower panel 12 is formed. Thereafter, a piece of fiberglass 20 is disposed on the lower panel 12 in order to prevent the panel from cracking. Thereafter, a heating cable 30 is placed on the fiberglass 20 before the liquid-powder mixture is solidified.
Subsequently, another piece of fiberglass 20 is disposed on the heating cable 30. Thereafter, an upper panel 14 is manufactured by charging the liquid-powder mixture to the height of the panel that is desired to be manufactured so as to cover the fiberglass 20 and solidifying the charged liquid-powder mixture.

Next, the operation and advantages of the heating apparatus for maintaining the temperature of a room according to the present invention, which is constructed as described above, are described below. First, when the main switch 201 of the control unit 200 is switched on, AC power is applied from the AC power unit 210 to the DC power unit 202. The DC power unit 202 converts the AC power into DC power (rectification) , and supplies the DC power to the microprocessor 203 as operational power. When the temperature of the electric heating plate 100, which is a desired radiant heat temperature, is set through the temperature setting means 204 while the operational power is supplied to the microprocessor 203, set temperature data is input to the microprocessor 203. The input set temperature data is stored in the RAM 205 of the microprocessor 203, and is also output from the microprocessor 203 to the relay coil RYl in the form of a control signal (current) .
Subsequently, the relay coil RYl is excited, so that the actuation contact a is electrically connected to the stationary contact b, therefore current, which is output from the AC power unit 210 via the main switch 201, flows through the lead wire 132, the electric heating cable 110 and the lead wire 134. Accordingly, the heat starts to be radiated from the electric heating cable 110, and thus the electric heating plate 100 is heated to a predetermined temperature .
In this manner, when the electric heating plate 100 is heated to the temperature set using the temperature setting means 204, the temperature sensor 150, which is mounted between the first and second contact terminals 142 and 144, detects the temperature of the electric heating plate 100, and outputs the detected temperature to the A/D converter 206. The analog temperature data input to the A/D converter 206 is converted into digital temperature data and is then input to the microprocessor 203. Subsequently, the microprocessor 203 compares the detected temperature with the set temperature, which is stored in the RAM 205. In this case, when the detected temperature is higher than the temperature set using the temperature setting means 204, no control signal (current) is output to the relay coil RYl by the microprocessor 203, so that the relay coil RYl is not excited, therefore the actuation contact a is separated from the stationary- contact b. Accordingly, no current flows to the electric heating cable 110, and thus the occurrence of fires, attributable to overheating, can be prevented.
Meanwhile, in the case where the electric heating plate 100 is overheated due to a malfunction of the temperature sensor 150, the bimetal 120, which is mounted in the intermediate portion of the electric heating cable 110, opens a circuit, and thus the occurrence of fires can be prevented.
In the present invention, the reason for mounting the temperature sensor 150 between the first and second contact terminals 142 and 144 is to prevent fires, attributable to overheating, from occurring by causing the temperature sensor 150 to detect the heat, which is generated due to sparks caused by poor contact between the lead wires 132 and 134, which are connected to the respective first and second contact terminals 142 and 144, and the electric heating cable 110, and to output the detection results to the A/D converter 206.
Furthermore, in the case where a selector switch or a push button switch is used for the temperature setting means 204, the temperature is increased or decreased in increments of 5°C, so that the temperature can be very easily set. In addition, in the case where a slide switch is used for the temperature setting means 204, the temperature can be more easily set. The heat insulating material 160 is any one selected from among ceramic fiber, rock wool and glass fiber, and the glass wool 170 is layered on the heat insulating material 160, so that the heat, which is radiated from the planar heating element 220, can be blocked so that it is not radiated to the outside through the rear of the heating apparatus for maintaining the temperature of a room according to the present invention, by which heat loss can be prevented.
Furthermore, in the heating apparatus for maintaining the temperature of a room according to the present invention, the frame 180 is formed of the aluminum chassis, which is formed by extrusion molding molten aluminum, so that cutting to a predetermined size and assembly are very easy, with the result that the structure of the heating apparatus is greatly simplified and the manufacturing cost can also be greatly reduced. The heating apparatus for maintaining the temperature of a room according to the present invention has a structure in which respective ends of the brackets 185 are inserted into through-holes 184a, which are formed in the ends of the first and second transverse aluminum chassis 182a and 183a, the respective remaining ends of the bracket 185 are inserted into the through-holes 187a, which are formed in the ends of the first and the second longitudinal aluminum chassis 185a and 186a, the screws 181 are inserted into the respective screw holes 188a and 188b, which are formed in the rear of the frame 180, in greater detail, which are formed close to the ends of the first and second transverse aluminum chassis 182a and 183a in the rear thereof and are threadedly coupled with the respective ends of the brackets 185, and the screws 181 are inserted into the respective screw holes 189a and 189b, which are formed close to the ends of the first and second longitudinal aluminum chassis 185a and 186a and are threadedly coupled with the respective remaining ends of the brackets 185. Accordingly, the frame 180 can be securely assembled.
Furthermore, in the heating apparatus for maintaining the temperature of a room according to the present invention, the through-holes 182c and 183c, which are spaced apart from each other and into which bolts (not shown) are inserted, are formed in the first and second transverse aluminum chassis 182a and 183a, or the through-holes 185c and 186c, which are spaced apart from each other and into which bolts (not shown) are inserted, are formed in the first second longitudinal aluminum chassis 185a and 186a, so that the heating apparatus for maintaining the temperature of a room according to the present invention can be easily installed to a support, which is provided on a wall or a ceiling.
As described above, the heating apparatus for maintaining the temperature of a room according to present invention can keep a room warm, can be easily handled because it is thin and light, and can prevent fires, attributable to overheating, from occurring.
Furthermore, the heating apparatus for maintaining the temperature of a room according to the present invention has various advantages in that it can promote blood circulation in the human body using far infrared rays radiated from a ceramic coating layer, which is coated with a material, which is obtained by mixing platinum powder having a nanoparticle size, silver powder having a nanoparticle size, and photocatalyst along with a mineral material, such as ceramic, when the ceramic coating layer is heated, can remove bad odors in a room by radiating negative ions, can kill bacteria that are harmful to the human body, has a simple structure, and has a low manufacturing cost.
