The present invention relates to a heating element, and more particularly, to a structure of a heating element that can enhance the electromagnetic shielding function using only electrical properties in the heating element itself without a separate component for electromagnetic shielding.

In general, a heating element using electricity is an electric heater, an electric stove, a heating furnace and a wire heating element made of a resistance wire of a predetermined thickness used in a warm clothes or a sleeping bag having a heating element, and a thickness below a predetermined thickness used in an electric blanket or a bed or a heat treatment device. There is a planar heating element consisting of a resistance line of.

The method of generating heat through such a heating element utilizes the collision of electric charges by applying electricity to the heating element by using the unique characteristics of the object (heating element). The heating element corresponding to this generally has a carbon fiber similar in crystal structure to carbon. (B) Carbon powders are widely used, and these heating elements generate heat by resistance generated in carbon fibers or carbon powder by applying a current to the carbon fibers or carbon powder.

However, since the heating element emits a large amount of electromagnetic waves harmful to the human body, various methods for blocking the electromagnetic wave have been devised. The most effective and widely used method is to weave or lattice a metallic thin plate or metal yarn around the carbon heating element. As a composition and a padding, copper is used a lot as such a metal.

For example, first of all, the prior art of the linear heating element, the Republic of Korea Utility Model Publication No. 1999-14187 'heating device for heat treatment device' and the 'non-magnetic heating wire' of the Republic of Korea Utility Model Publication No. 1998-62426 is known There is a bar.

In the heating wire structure of the prior art, a glass yarn braided layer and an asbestos braided layer are formed around the carbon heating core, respectively, and the first and second embodiments are coated on the outer circumference thereof. An Al thin film layer, a copper wire woven layer, a metal foil coating layer, etc. which can block electromagnetic waves between the coating layers are respectively configured.

Another prior art, Korean Patent Application Publication No. 1999-14240, `` magnetic field-type heating element using a linear heating element of Car Headquarters, '' has a carbon yarn linear heating element having a predetermined heat resistance, and an exposed surface of the carbon yarn linear heating element. An insulator processed by braiding and rinsing, and a metallic conductor having substantially the same length as the carbon yarn linear heating element and coated with at least any one of enamel, nickel and Teflon in a predetermined order, etc.

On the other hand, when looking at the conventional technology of the planar heating element using carbon, Korean Utility Model Publication No. 1998-25079, 'Thermal mat with electromagnetic wave blocking function' has been introduced, the configuration is the copper wire blocking member Iii) and aluminum plate for water-wave blocking and heat reflection function is formed between the electric heating heater layer and the human body, that is, copper and aluminum plate are formed separately from the carbon heater layer, and also other minerals in the carbon material. It also describes that the fiber layer can be used interchangeably.

However, the linear and planar heating elements that generate heat due to this action, first, when using carbon fibers or carbon powder, the resistance value is not constant when heat is generated from the carbon fibers due to the resistance, thereby causing local overheating and heating. In addition, there is a disadvantage in that carbon is exhausted and its life is short, and in order to remove electromagnetic waves generated by physical or electrical characteristics that generate heat by collision of charges, in the case of a planar heating element, a shielding film different from the carbon layer (copper film, silver foil paper) , Gold foil, etc.), and the linear heating element has a very complicated structure such as incorporating a silicon layer, a copper wire woven layer, or a metallic property on the outer circumference of the carbon core material.

In particular, in the case of the planar heating element, since the carbon paste layer is formed over the entire heating area and the electricity is applied thereto, the heat generating is generated by the electrical resistance. Therefore, a metal film or a metal fiber woven layer, which is an electromagnetic shielding means generated in the resistance heating element, Since it has to be laminated or coated separately, the manufacturing process is complicated and the use of excessive materials has a problem of poor productivity and high manufacturing costs.

Accordingly, the present invention was created in order to solve the above problems, and an object of the present invention is to improve the electromagnetic shielding function by improving only the electrical characteristics of the harmful electromagnetic waves generated after power supply without using a separate electromagnetic shielding agent. It is to provide a heating element that can be further improved.

In addition, another object of the present invention is to provide a heating element that is easy to manufacture and can reduce the manufacturing cost.

The object is to print the (+) side conductor and (-) side conductor, which are generated by conduction on a nonwoven fabric or fabric of non-conductor fabric of the size of the area to be heated, in a line shape or a plane having a constant width, It is achieved by enabling them to be conducted through copper wires and simultaneously installing copper wires on the textile paper or fiber yarn to shield electromagnetic waves at the same time as heat generation.

According to the present invention, a fabric paper having a predetermined thickness and width, opposite to both ends of the fabric paper, is provided with a power supply (+) (-) electrode for receiving a predetermined voltage, and one end is attached to the (+) electrode. The other end is provided with a plurality of first conductors to face the (-) electrode, one end is attached to the (-) electrode and the other end is provided to face the (+) electrode, the predetermined distance from the first conductor Electromagnetic waves are provided between a plurality of second conductors arranged to maintain the second conductor and the (+) (-) electrodes and are induced when a predetermined heat is generated due to collision of different charges flowing through the first conductor and the second conductor. It is characterized by including a plurality of copper wire for absorption.

In addition, the first conductor and the second conductor may be screen-printed in the form of a conductive powder selected from any one of carbon, boron, and nickel.

In addition, a first induction ground line for absorbing and grounding electromagnetic waves induced around the (+) (-) electrodes may be further provided at one side of the power supply (+) (-) electrodes.

With reference to the accompanying drawings, a heating element having an electromagnetic shielding function according to the present invention will be understood by the embodiments described in detail below.

As shown in FIG. 1, the planar heating element 100 has a predetermined thickness and width and is provided in a sheet-shaped ordinary fabric paper 110 and opposite sides of the fabric paper 110 so as to face each other. Power supply (+) electrode 120 and (-) electrode 122 for receiving a predetermined voltage through the (not shown), one end is attached to the (+) electrode 120 and the other end is ( A plurality of first conductors 124 which are provided to face the electrode 122 and do not actually touch the (-) electrode 122, one end of which is attached to the (-) electrode 122 and the other end of which A plurality of second conductors 126 which are provided to face the (+) electrode 120 and do not actually touch the (+) electrode 120, and are arranged to maintain a predetermined distance from the first conductor 124; A predetermined heat is generated between the (+) (-) electrodes 120 and 122 due to the collision of different charges flowing through the first conductor 124 and the second conductor 126. As it is configured to include a plurality of copper wires (130) for absorbing an electromagnetic wave derived.

The first conductor 124 and the second conductor 126 is made of a powder having conductivity, but the conductive powder is not particularly limited as long as it has conductivity, but any one selected from carbon, boron, and nickel may be used. In view of conductivity and handleability, it is preferable to use carbon.

The carbon, boron, nickel is basically used to have a particle size of approximately 50-300 mesh, preferably 150-300 mesh. Of course, one having a nano-sized particle size can also be used.

(Generated by collisions between charges of different polarities), and at this time harmful electromagnetic waves are generated.

The electromagnetic wave generated in this way is between the power supply (+) (-) electrodes 120 and 122, more specifically, the power supply (+) (-) electrode 120 as in the embodiment of the present invention.
