HEAΉNG APPARATUS FOR THERMAL INSULAΉNG

IN ROOM TEMPERATURE

[Technical Field]

The present invention relates generally to a heating apparatus for maintaining the temperature of a room and, more particularly, to a heating apparatus for maintaining the temperature of a room, which can keep a room warm, can be easily handled because it is thin and light, and can prevent fires, attributable to overheating, from occurring and, in addition, which 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 a photocatalyst along with mineral material, such as ceramic, when the ceramic coating layer is heated, can remove bad odors in a room by radiating negative ions, and can kill bacteria that are harmful to the human body.

[Background Art]

A prior art heating apparatus for maintaining the temperature of a room, which is widely used, is disclosed in Korean Unexamined Pat. No. 10-2002-54687 (which was published on July 8, 2002) .

In the heating apparatus for maintaining the temperature of a room, which is disclosed in Korean Unexamined Pat. No. 10-2002- 54687, a liquid-powder mixture is manufactured by manufacturing crushed rock by crushing a white stone or a white rock, adding crushed gemstones, which are obtained by crushing gemstones, to the crushed rock, and mixing the powder with an aqueous solution.

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. Thereafter, when the solidified panel 10 is separated from the moldbase, a final electric floor-heating panel, in which the heating cable 30 is completely and integrally buried, is manufactured.

The prior art electric floor-heating panel is advantageous in that the strength thereof is high, and in that the upper panel 14 and the lower panel 12 are manufactured using the crushed gemstones, to which the crushed rock, which is obtained by crushing white stone or white rock, is added, so that far infrared rays can be radiated when power is applied to the heating cable 30, therefore blood circulation can be promoted and harmful waste material in the human body can also be discharged to the outside, but is problematic in that the upper panel 14 and the lower panel 12 are manufactured using the crushed rock, so that it is difficult to handle because it is heavy.

Furthermore, the prior art electric floor-heating panel is problematic in that the manufacturing process is complicated, and thus a high manufacturing cost is required, and in that, if overheating beyond a predetermined temperature occurs, power applied thereto cannot be interrupted, and thus fires cannot be prevented.

The control unit 200 includes a main switch 201 for switching the output of power applied by an AC power unit 210, a DC power unit 202 for receiving the power from the AC power unit 210 and converting the received power into DC power when the main switch 201 is switched on, a microprocessor 203 for receiving the DC power, which is output from the DC power unit 202, as operational power and controlling the overall operation of the apparatus, a temperature setting means 204 for setting the radiant heat temperature of the electric heating plate 100 in the microprocessor 203, Random Access Memory (RAM) 205 for receiving temperature data, which is set using the temperature setting means 204, through the microprocessor 203 and storing the received temperature data, a relay coil RYl, excited by a control signal (control current) , which is output from the microprocessor 203, and electrically connecting an actuation contact a to a stationary contact b so that current is applied to the electric heating plate 100 according to the temperature data set using the temperature setting means 204, and an Analog/Digital (A/D) converter 206 for converting analog temperature data about the heat, which is radiated from the electric heating plate 100, into digital temperature data and outputting the digital temperature data to the microprocessor 203, the analog temperature data being detected by a temperature sensor 150 and being received through the lead wires 152 and 154. The temperature setting means 204 may be a selector switch or a push button switch, through the manipulation of which the temperature is increased or decreased in increments of 5⁰C.

Furthermore, the temperature setting means 204 may be a slide switch.

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. As shown in FIG. 8, the electric heating cable 110 that is used in the heating apparatus for maintaining the temperature of a room according to the present invention is configured such that the first Teflon layer 112 and a silicon insulating layer 113 sequentially cover a plurality of strands of twisted copper wire 111, so that a working voltage of more than 2000 VAC at 10 mA AC is generated by the first Teflon layer 112, and a working voltage of 2000 VAC at 10 mA AC is generated again by the silicon insulating layer AC, so that the electric heating cable 110 can withstand a total working voltage of about 4000 V. Furthermore, the second Teflon layer 115 is wound around the heating wire 114, which is helically wound around the silicon insulating layer 113, and the second Teflon layer 115 prevents the heating wire 114, which is formed of Nichrome wire, from moving, so that, when the heating wire 114 is covered with insulation material, such as silicon rubber, through extrusion molding, a phenomenon in which the heating wire 114, which is helically wound around the silicon insulating layer 113, is pushed to one side by the extrusion force is prevented, therefore the occurrence of defective products can be prevented when the electric heating cable 110 is manufactured, and thus the production yield can be improved. In addition, the heat, which is radiated from the heating wire 114, is indirectly transmitted to the insulating layer 116 through the second Teflon layer 115, so that the insulating layer 116 can be prevented from being deteriorated by the heat, and the lifetime of the electric heating cable 110 can be elongated. Furthermore, the heating wire 114 is helically wound around the silicon insulating layer 113, so that, even when power is applied between the copper wire 111 and the heating wire 114, the electromagnetic waves, which are radiated from the copper wire 111, are absorbed by the heating element 114, and thus the electromagnetic waves, which are harmful to the human body, are not emitted to the outside.
