Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planar heating element,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a planar heating element, and more particularly, to a planar heating element which is prevented from sparking and short-circuiting, has a simple structure, is easy to manufacture and has improved applicability, and a heating device using the same.

Generally, various types of heating elements that convert electric energy into thermal energy are used for heating or receiving heat above a certain temperature. Due to the portability and applicability of various heating elements, research and development of surface heating elements have been actively conducted.

1 and 2, a conventional general surface heating element is formed by applying a liquid carbon paste or a carbon ink to an upper surface of a lower film 1 having excellent insulation property at a proper interval to form a plurality of carbon bands 2, (For example, a silver paste) is applied in the longitudinal direction of both ends of the film so as to connect the ends of the carbon strip 2 to each other so as to increase the amount of heat generated after the film is formed in the transverse direction of the film 1 To form the conductive strip 3 and then to laminate the copper foil 4 on the conductive strip 3 and then to bond the lower film 1 to the upper film 5 via the adhesive sheet, Laminating bonding. A wire for terminal treatment is soldered to one end of each of the copper foils 4 and a temperature sensor or a bimetal is attached to the outer surface of the lower film 1 or the upper film 5 on which the copper foil 4 is located So as to control overheating of the planar heating element.

When current is supplied to the copper thin plate 4 through the electric wire, a current flows through the conductive band 3 to flow a current to the carbon band 2, and the carbon band 2 The resistance heat is generated due to the resistance formed in the insulating layer.

However, in a conventional surface heating element manufactured by using a conventional carbon paste or carbon ink, a unit carbon band in a state in which a carbon paste or a carbon ink having a high specific resistance value per unit area is applied / dried has a large amount of electric current , There is a problem that the maximum temperature that is generated with respect to an AC220V input voltage usually shows a relatively low temperature of about 50 to 60 degrees Celsius. Of course, if the carbon paste or the carbon ink is formed on the same carbon band, the resistance value formed on the unit carbon band can be lowered, thereby increasing the heat generation temperature. In this case, however, there is a problem

In addition, in the conventional surface heating element, it is difficult to control the properties of the adhesive sheet so as not to invade the conductive paste area in the electrode treatment of the heat generating part, and also in the case of laminating adhesion, the copper plate laminated on the conductive paste, And a short circuit is generated to cause a failure or a failure.

In particular, when a silver paste is used as a conductive paste in the contact between the end portion of the heat generating portion and the electrode, the manufacturing cost is increased, the manufacturing process is increased and the productivity is lowered. In addition, defective due to incomplete contact between the heat generating portion and the electrode .

In addition, in a conventional heating element based on carbon paste or carbon ink, the heat generation amount is lowered due to the high resistance of the heating element and the low input voltage in a country or region where an AC 100 V or AC 110 V voltage is used.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to reduce the resistance of a unit carbon band so as to achieve the same heating value as a heating element used at AC220V even at a voltage of AC100V or AC110V, And a short circuit is prevented, safety and reliability are improved, an inexpensive contact means is not used, it is inexpensive and easy to manufacture, yield is improved, and an improved heating process is provided through an improved electrode process, There is provided a planar heating element in which a flat surface is not maintained because the heating element can not be expanded due to a fixed frame due to thermal expansion of the heating element even if the mounted heating element is heated, and a heating device using the same.

It is another object of the present invention to provide a planar heating element which can be used as a heating element and a screen for a heating element using a heating substrate material having a large thermal expansion coefficient as well as a heating substrate having a small thermal expansion coefficient.

It is still another object of the present invention to provide a method and a device for displaying various information on a heating element and a heating device equipped with the miniature chip LED by arranging miniature chip LEDs between carbon bands in the heating element and carbon bands adjacent thereto, There is.

It is a still further object of the present invention to provide an air conditioner in which a fan for performing an intake or exhaust operation is mounted on the ends of supports at both ends for housing a heating element to perform a forced intake or exhaust operation by the fan through a ventilation hole between the heating element and both side supports Which is used as an electric fan, an air purifier or a laundry dryer when not used as a heating device, as well as improving the heating performance.

The above objects are achieved by a non-flexible substrate sheet such as a flexible substrate sheet or a sheet glass mainly composed of polyester (PET), polyethylene naphthalate (PEN), polyimide (PI), polyurethane or fiber reinforced plastic (FRP) A heating member integrally attached to the substrate sheet at a predetermined interval; A power distributing plate disposed symmetrically on both sides of each of the heat generating members, the power distributing plate being formed by integrally adhering and arranging electrode bodies by conductive adhesive to each of the heat generating members; And an electrode disposed at each end of the power distribution board.

According to one aspect of the present invention, the heating member is composed of a carbon ink, which is integrally applied to the substrate sheet, and a conductive material, which is mixed with the carbon ink.

According to another aspect of the present invention, a conductive material is a highly conductive carbon-based material such as graphene or carbon nanotube (CNT), which is a material that can be well mixed with a carbon ink, It is a substance that reduces the amount of far-infrared ray radiation when heat is generated.

According to another aspect of the present invention, one or more surface heating elements corresponding to different input voltages are integrally coupled to each other by an adhesive member made of a vapor deposition adhesive film or an adhesive sheet to form a multi-surface heating element, The planar heating element further includes an electrode member integrally adhered to each of the heating members.

According to another aspect of the present invention, there is provided a method of manufacturing a semiconductor device, including the steps of: directly soldering a wire for wiring to the end of a metallic electrode body such as a copper tape coated with an electrically conductive adhesive in a state where the electrically conductive paste is removed; And the terminal for the electrode is treated in such a manner that a small-length copper tape coated with the electrically conductive adhesive is attached to the electrode body at the end of the heating element.

The above objects are also achieved by a heating apparatus incorporating a planar heating element, the heating apparatus including a substrate sheet, at least one heating member attached to the substrate sheet, and a heating member disposed symmetrically on both sides of the heating member, A planar heating element having an electrode plate formed integrally with and bonded to the electrode plate; And a side support for supporting a planar heating element on a side surface of the planar heating element.

According to the planar heating element of the present invention, a heating element having a low resistance can be formed by a conductive material mixed with a heating member, and the same heating value as in AC 220 V can be obtained even at a low input voltage of AC 110 V or AC 100 V, Since the expensive conductive paste such as paste is not used, the manufacturing process is simple, the manufacturing cost is reduced, and the electrode treatment is carried out by attaching the wire for direct wiring directly to the conductor separated from the heating element, , A conductor protruding to the outside of the body of the heating body is not required, so that there is a remarkable effect in manufacturing a standardized heating body.

In addition, since the heating of the heating element is prevented from being bent due to the thermal expansion of the heating element in the state where the heating element is mounted on the outer fixing frame, the constant flatness of the heating element can be maintained to provide not only a relatively expensive heating substrate material having a small thermal expansion coefficient, It is possible to use it as a heating element and a screen utilizing a low-cost heating substrate material having a large coefficient.

In addition, miniature chip LEDs may be arranged between the carbon strips arranged in the heating element and the adjacent carbon strips at regular intervals to display various information about the heating element and the heating device equipped with the heating element, and a message to be displayed by the user.

10 is a perspective view showing one application example of the planar heating element according to the present invention.

Hereinafter, a planar heating element according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.

3, the planar heating element according to the present invention basically includes a base sheet 10 constituting a base or base. The substrate sheet 10 may be formed of a sheet of flexible material such as polyimide (PI), polyethylene naphthalate (PEN), polyester (PET), or polyurethane, A non-flexible sheet such as a fibrous semispherical sheet mainly made of plastic (FRP) or a sheet glass having a small thermal expansion coefficient and a high thermal conductivity can be used.

For example, the substrate sheet 10 may be formed by mixing carbon micro-fiber, pulp for paper, water-soluble binder, water, etc. with polyimide, polyethylene naphthalate (PEN), polyester, polyurethane, fiber reinforced plastic It is preferable to be formed of a conductive material having a resistance or a conductive material having a basic resistance by mixing a conductive compound with carbon ink or carbon ink. Of course, when the substrate sheet 10 is flexible, unlike the case where the substrate sheet 10 is semi-flexible or non-flexible sheet, the substrate sheet 10 can be formed into a corresponding thickness and size and stored or transported in a roll form.

3, a plurality of or a plurality of heating members 20 having a predetermined width or size are integrally attached to the substrate sheet 10 at regular intervals. Each heating member 20 is formed of a carbon component as a main component.

Further, a power distributing plate 30 is connected to each of the heating members 20 so as to actually supply electricity. It is preferable that the power distributing plates 30 are disposed symmetrically on both sides of the respective heat generating members 20.

4 to 6, each of the heating members 20 is formed by mixing a conductive material 24 with a carbon ink 22, . For example, each of the heating members 20 may be formed of a conductive material such as graphene or carbon nanotube (CNT), which can be mixed with carbon ink as a carbon-based material having high electrical conductivity, in the liquid carbon ink 22 24) are mixed with each other. The mixing ratio of the conductive material (24) to the carbon ink (22) may be set arbitrarily according to purposes and applications.

Each of the heating members 20 may be formed in various shapes such as a bar, a wire, and a band. It is preferable that the heat generating members 20 are integrally attached to the substrate sheet 10 by various printing methods. Of course, the sizes, thicknesses, sizes, and mutual intervals of the respective heat generating members 20 can be variously set according to the purpose and application to which they are applied.

Alternatively, a functional line such as a resistance line may be wired to each heating member 20 to improve safety and reliability, or a crack of the heating member 20 due to an artificial tension as much as using a flexible substrate material And the insulating sheet 40 material having the purpose of restricting an artificial tensile force can be used. Here, the wiring fiber used for preventing the cracks of the heat generating member 20 may be made of carbon fiber or a carbon fiber-deposited fiber having the purpose of lowering the resistance of the heat generating member 20.

Each of the power distributing plates 30 has an electrode body 32 formed of copper with excellent electrical conductivity and an adhesive 34 formed to integrally adhere and fix the electrode body 32 to the respective heat generating members 20 without gaps or gaps ).

Each of the electrode bodies 32 is preferably formed of an aluminum tape, a copper tape, or a copper tape, which has excellent conductivity and flexibility and is inexpensive. The adhesive 34 is preferably formed of a conductive adhesive having excellent electrical conductivity while maintaining excellent adhesiveness. The electrically conductive adhesive 34 is preferably formed by mixing one or more of the various conductive fillers with the adhesive resin.

Therefore, the power distributing plate 30 can be directly brought into electrical contact with the respective heat generating members 20 without using an expensive material such as silver paste, so that spark and contact failure can be prevented, The cost can be reduced.

After the power distributing plate 30 is bonded to both ends of the heat generating member 20, a separate insulating sheet 40 is adhered to the upper surface of the power distributing plate 30. To ensure smooth adhesion, a separate adhesive film (not shown) (Not shown) is placed between the insulating sheet 40 and the heat generating member 20 and the power distributing plate 30, and the heat pressing roller is passed through the evaporator to produce the integrated basic heat generating body 100.

At both ends of the basic heating element 100, temperature detecting means 28 and 29 are attached to the power distributing plate 30 through an adhesive.

The external temperature detecting means 28 in Fig. 4 is constituted by two electric wires 281, a temperature sensor 284 and a bimetal 286, and a temperature sensor 284 is connected to electric wires 281, And the bimetal 286 are soldered together.

In this case, a thermistor is used as the temperature sensor 284, and the bimetal 286 is a normally-open type that is opened when the bimetal 286 is not overheated.

The external temperature detection means 28 in which the temperature sensor 284 is connected in parallel to the normally open type bimetal 286 is connected to each temperature sensor 284 by a resistance of several megaohms or more corresponding to the bimetal 286 Resistances equivalent to several kilo ohms or tens of kilo ohms are interpreted in the same manner as a parallel connected structure.

Therefore, the summing resistance of the thermistors connected in parallel is controlled by the dominant influence by the thermistor which detects the highest temperature and shows the lowest resistance value.

If the heating element is out of the normal temperature range, the bimetal 286 is operated. At this time, since the bimetal 286 is internally connected, the resistance value actually appearing is zero, The summation resistance is neglected and acts as a resistance under bimetal 286 control.

However, due to a problem in the assembling position of the external temperature detecting means 28, the temperature sensor of the external temperature detecting means 28 can not detect the actual heat generating temperature occurring inside the heat generating element, And senses the conducted heat. Therefore, the control unit (not shown) for controlling the heating element has a lookup table. For example, if the sensor detects 50 degrees, it recognizes 80 degrees. If the sensor detects 60 degrees, it recognizes 90 degrees.

Assuming that the upper limit of the rated temperature of the basic heating element 100 is 100 degrees, if the temperature at the center of the upper end of the basic heating element 100 is 100 degrees and the temperature of the upper end of the side power distributing plate 30 is 70 degrees, The bimetal 286 operating in the external temperature detecting means 28 is used.

Thus, the external temperature detection means 28 of FIG. 4 is an indirect temperature recognition method using a look-up table, so that the accuracy of temperature detection is lowered, and the external temperature type detection means 28 of FIG. do.

In order to solve such a problem, the built-in temperature detecting means 29 shown in Fig. 4 is arranged at predetermined intervals before the insulating sheet 40 is deposited, and a temperature sensor (not shown) is disposed between the heating member 20 and the adjacent heating member 20 294 are disposed.

The built-in temperature detecting means 29 uses a micro temperature sensor 294 having a temperature sensor of 0.5 mm or less and maintains the arrangement direction of the temperature sensor 294 in the direction of 90 degrees to the electric wire 291, The lead wire 293 of the sensor is assembled in such a manner that the lead wire 293 is soldered to the wire whose strip is removed in the middle and the bimetal 295 is assembled in the same manner as the external temperature detecting means 28, And is assembled after the deposition process is completed. Preferably, the bimetal 295, like the temperature sensor 294, should be assembled together in a 90 degree orientation with respect to the wire 291, but the structural characteristics of the bimetal 295, which is mechanically contacted by the detected temperature, And it is an object to prevent damage to the bimetal 295 or the rollers of the evaporator in the process of depositing the insulation sheet 40 of the basic heating element 100 because it is difficult to manufacture it in a very small size like the phase temperature sensor 294.

The built-in temperature detecting means 29 in which the bimetal 295 is not assembled is disposed inside the heating element so that the temperature sensor 294 is placed between the heating members 20, (30) or at the outer edge beyond the power distribution board (30).

At this time, a separate insulating tape (not shown) such as a paper tape is attached to the upper end of the power distributing plate 30 at a place where the lead wire 293 of the temperature sensor overlaps with the power distributing plate 30, The portion where the bimetal 295 is exposed is cut off in advance and the deposition proceeds.

In the case of the built-in temperature detecting means 29, since the temperature is directly detected inside the basic heating element 100, the accuracy is high and a separate look-up table is not required in the control portion (not shown) .

5 is a cross-sectional view of the internal / external temperature detecting means 28, 29 and the insulating sheet 40 in a state of being laminated. In the figure, there is a space between the insulating sheet 40 and the heat generating member 20, The insulating sheet 40 maintains a state in which the heating member 20, the inner temperature sensor 294, and the substrate sheet 10 are in close contact with and fixed to each other while being subjected to a deposition process.

Fig. 6 is an enlarged sectional view taken along the line IV-IV in Fig. 5, showing a heating member 20 formed on the substrate sheet 10 by a silk screen printing method, an electrically conductive adhesive 34 at the end of the heating member 20, The insulation sheet 40, the temperature sensor 284 and the bimetals 286 and 295 constituted by the electrode body 32 to which the bipolar plate 28 is applied.

In particular, the heat generating member 20 formed on the substrate sheet 10 by the silkscreen printing method should have the same or similar calorific value as the AC 220 V power source when the power is supplied to AC 110 V or AC 100V. In order to achieve this, W = V * (V / R) (where Watt is the power consumption, V is the input voltage, and R is the heating element resistance), so if the input voltage is lowered, the same power consumption The resistance value should be the heating member 20 having a resistance value significantly lower than the inherent resistance of the existing heating member 20.

The heating member 20 of the present invention includes a liquid carbon ink 22 formed by mixing a carbon material 22 with a conductive material 24 made of graphene or carbon nanotubes ) Based low resistance heating member 22 is used.

The carbon ink 22 may be made of a metal material based on electrically conductive material such as silver compound or aluminum powder as the conductive material 24 added for the purpose of lowering the resistance value of the heating member 22 And a unit 22 of the heating member 22 when the heating member 22 formed by adding carbon material-based graphene or carbon nanotube, which is the same as the carbon powder as the main component of the carbon ink 22, The far infrared ray emission amount per unit area is characterized in that more far infrared rays are emitted than the heat generating member 22 formed by adding the conductive material 24 based on the metal material.

7 is a view showing a temperature sensor, a control signal, a control DC power supply, a message display LED, a wiring diagram, and a component placement block diagram, which are additionally provided in the basic heating element 100 according to the present invention.

The basic structure of the heating element including the substrate sheet 10, the heating member 20 and the power distributing plate 30 is the same, but in FIG. 4, the temperature detecting means 28, 29 having lead wires of two pins like a thermistor on both sides of the heating element 7, it is characterized in that two lead wires are used for the left and right sides of the temperature detecting means 28 and 29 for different purposes, so that a temperature sensor of a more accurate integrated circuit (IC) type can be used .

This configuration will be described in detail as follows.

That is, the temperature sensors A1 to A4 and B1 to B4 of the direct circuit type, the thermocouple 33, the DC power supply voltage wiring (VCC, GND) for the temperature sensor of the direct circuit type, SDA, and SCL), a printed circuit board 39, and the like.

The temperature sensors A1 to A4 and B1 to B4 of the integrated circuit type are serial communication systems and have two communication means pins and a plurality of temperature sensors A1 to A5 and B1 to B5 A temperature sensor having a pin capable of designating an address for a temperature sensor is mainly used.

4, the thermocouple 33 is disposed at the upper end for the purpose of detecting the temperature inside the basic heating element 100, and the whole of the basic heating element 100 ) Of the thermocouple 33 is placed at the inner two positions.

By providing the temperature detecting means at the upper end or the uppermost end of the heating element 100, when the foreign matter is put on the upper end of the heating element 100 in the inverted U-shape, the heating element 100 is overheated by the impurity of the foreign matter It is an object of the present invention to prevent the heating element 100 from being damaged due to overheating because the temperature sensor provided on the side does not directly detect such a state.

The thermocouple 33 is a temperature detecting means using an induced voltage between two metal lines generated by welding the lead terminations of two metal wires having different thermal expansion coefficients and causing the welded portions to expand differently between the two metal materials due to heat generation, The two leads of the thermocouple 33 are connected to the signal amplifiers A5 and B5 for amplifying the induced voltage of one signal and the amplified signals are amplified by the signal amplifiers A5 and B5 directly to the signal amplifiers A5 and B5 The amplified signal voltage output from the amplifiers A5 and B5 may be communicated using an I2C communication line, that is, using SDA and SCL, or may be connected to an analog-to-digital conversion port (ADC Port) of a microcontroller unit It is possible to read the temperature of the thermocouple 33 located in the deep portion of the basic heating element 100 by communicating using the I2C communication line provided in the MCU (not shown).

The two lead wires for the temperature detection means 28 on the right side in Fig. 7 are also serial communication signals of I2C type, which are operated by two lead wires, as SDA (Serial Data) and SCL (Serial Clock) The two lead wires for the temperature detecting means 29 are allocated for VCC and GND for the DC drive voltage of the temperature sensor of the direct circuit type, respectively.

The signal wirings for driving the four integrated circuits thus allocated are cross-wired to the left and right sides as shown in Fig. 7 so as not to overlap with the heat generating member 20 at any positions of the lower end, the center, and the upper end of the heat generating element.

In the above description, the operations of the thermocouple 33 and the temperature sensors A1 to A4 and B1 to B4 of the direct circuit type are described for the purpose of replacing the inner / outer temperature detecting means 28 and 29 of FIG. The controller C1 and the control switch PWR are provided on the left and right sides of the basic heating element 100 without the control unit C1 and the power supply unit PWR outside the basic heating element 100 in a state of maintaining the configuration S1), status display means (LED and / or LCD, not shown), and a wireless communication module WM which is not controlled from the outside.

In this case, the terminals (SDA, SCL) protruding to the outside for serial communication are unnecessary for the basic heating element 100, and the terminals (VCC, GND) allocated for the DC driving voltage do not need to protrude to the outside.

However, only the left and right power inlet terminals (not shown) projected to the outside are connected to the power distribution board 30, and a separate power distribution board branched from the left and right power distribution boards 30 enters the left power source unit PWR At this time, an insulating tape having a thick thickness is inserted in the portion where the power distribution boards 30 intersect to securely insulate.

The DC power generated by the power supply unit PWR is supplied to the switch panel S1 in which the control unit C1, the temperature sensors A1 to A4 and B1 to B4, the signal amplifiers A5 and B5 and various control switches (not shown) And is connected to the intake / exhaust fan 31 disposed at the upper left / right side via a separate connection connector (not shown).

The structure for preventing the external cold air introduced from the intake / exhaust fan 31 from affecting the temperature sensors A1 to A4 and B1 to B4 disposed on the side surface is related to the side support 50 of Fig. 9 Will be described later in the description.

Meanwhile, in the heating element 100 of the present invention, a microchip LED is disposed between the heating element 20 and the heating element 20 at regular intervals. When the drying process of the silk printing for the heat generating member 20 is completed for this purpose, the signal wiring (not shown) for driving the LED is formed by the silk printing method.

The LED driving signal wiring (not shown) formed as described above passes through the lower end of an insulation tape (not shown) of a portion overlapping with the power distribution board 30 on the side surface portion of the heating element 100, And is connected to the printed circuit board 39 on which the LED driving units D1 to D4 are mounted through a separate FPCB based flexible cable in a state where the basic heating element 100 is assembled.

The LED driving units D1 to D4 are connected to one port (not shown) of the control unit C1 and connected to the input / output port of the wireless communication module WM at another port (not shown) of the control unit C1.

The component mounting of the LED having the arrangement structure as shown in FIG. 7 is mounted on the substrate sheet 10 in the same manner as the LED mounted on the general membrane switch panel, and is coated with the insulating sheet 40, thereby maintaining the solid state.

The LEDs arranged according to such a circuit configuration display various status information (temperature and temperature for each set, set time and remaining time, cumulative power consumption and average power consumption) sensed by the control unit C1, And the like.

Here, the wireless communication module includes wireless LAN, Bluetooth, NFC, and Zigbee.

It is also possible to use the heating element 100 for controlling the heating element 100 at a distance or near by the wireless communication module WM.

8A to 8D are terminal processing structure diagrams of the electrode portion at the end of one side power distributing plate 30 of the planar heating element according to the present invention.

8A shows a state in which the wiring board 35 and the wiring board 35 are soldered to the longitudinal end surface of the lower end of the power distribution board 30 which is brought into close contact with the lower end of the substrate sheet 10 and then the power distribution board 30 and the insulator 36 Preferably, the insulator 36 is also closely attached to the lower end of the insulator 36 so that the insulator 36 is curled in a U-shape in the direction of the upper surface to prevent any electrode plate 37 from being exposed to the outside.

8B shows a state in which the wiring wire 35 is soldered to a separate electrode plate 37 of the same material as the electric distribution board 30 to which the electrically conductive adhesive is applied and then the electric wire is simply attached to the surface of the electric distribution board 30 And the electrode is treated in a manner of attaching the electrode.

8C shows that when the deposition process is performed while the power distribution board 30 protrudes to the outside of the substrate sheet 10, the protruding surface of the power distribution board 30 with the coating of the electrically conductive adhesive is contaminated with foreign matters such as dust, And the power distribution board 30 is not protruded to the outside of the substrate sheet 10, so that it is more standardized and easy to handle. In the same manner as in FIG. 8B, In order to do this, the insulating sheet 40 should have a corresponding region where the electrode is to be attached before the deposition process is performed, as shown in FIG. 8B.

Fig. 8D is basically the same as Fig. 8C, but the difference is that the portion of the insulating sheet 40 to be cut in advance is inverted U-shaped.

As described in the description of FIG. 8A, in order to insulate the exposed portion of the electrode plate 37 to which the wiring wire 35 is attached in FIGS. 8A to 8D, There is a need for means to further reinforce or replace the insulating tape or insulating sheet as the insulator 36. [

That is, the electrode plate 37 to which the wiring wire 35 is attached is exposed to air while using a heating element, and there is a possibility that the adhesive portion may be deteriorated or dropped over a long period of time due to the restoring force of the bent wiring wire.

In order to prevent this, a plastic injection molded article having a simultaneous elastic force and being electrically insulated is inserted into the U-shaped heating element or the electrode plate 37 having the wiring wire 35 attached thereto at the lower end or the side surface thereof, It is necessary to maintain a state in which the bottom surface of the plate 37 can be brought into close contact. As another method, a hard sponge or elasticity slightly thicker than the gap between the electrode plate 37 and the supporter 50 by using the elastic force of the outer wall of the supporter 50 including the distribution board 30 and surrounding the heating element side, It is possible to keep the state in which the electrode plate 37 is in close contact with the power distributing plate 30 and to add an electrical insulation function.

9A and 9B show a side support 50 and an internal structure of the present invention. As shown in FIG. 9A and FIG. 9B, an L-shaped or a U-shaped bracket (not shown) fixed to the left / 52, a hexagonal bracket 53 fixed to an L-shaped bracket 52, a hexagonal bracket 53 fixed to the bracket 52, a power source PWR, a control unit C1 and a switch panel S1, Like elastic bracket 52 for fixing the basic heat generating element and elastic spring panels 54 and 55 positioned between the inner protrusions of the side support 50 Element.
