In general, electromagnetic waves are always generated from electronic products using electricity. The electromagnetic wave may be referred to as 'a kind of energy wave having a wide range generated in the flow of electricity and magnetism'.

The use of electricity has already become inevitable in modern life. The electricity that causes electromagnetic waves must be convenient and clean energy. And household appliances that emit electromagnetic waves, like TVs and PCs, have also become part of our lives. However, not many people know how harmful electromagnetic waves emitted from such clean and convenient electric and electronic products are.

Nowadays, newspapers and broadcasts are flooding with the results of various studies warning of the harmfulness of electromagnetic waves. However, the first study of the correlation of electromagnetic waves to human health was first conducted in 1979 by Dr. Nancy Waltheimer and Dr. Edifer. As a result of continued research, the relationship between electromagnetic waves and some types of specific cancers has been revealed, and now, the correlation between all kinds of cancers and electromagnetic waves is under study.

These studies are mainly conducted using animal or animal tissues, which show that even healthy animal cells can be affected by normal biological function after prolonged exposure to electromagnetic waves.

In addition, the findings of this study allow not only to explain the causes of silk cancer, but also to explain the causes of various mental disorders such as' sleep disorder, 'low learning ability' and 'neural weakness'.

In modern society, the damage caused by electromagnetic waves is very wide and varied, ranging from small sleep disorders to scary diseases such as cancer and leukemia.

Electric and electronic products enrich and enrich the lives of human beings, but the by-product electromagnetic waves continue to cause great damage to our human body.

For this reason, a new term called 'electromagnetic pollution' has emerged. In addition, electromagnetic waves are now recognized as the fourth pollution along with air, soil and water pollution.

Looking more closely at electromagnetic waves, electromagnetic waves are a kind of electromagnetic energy with a wide frequency range ranging from 0 직류 direct current to 10 ²² ㎐ gamma rays, depending on the frequency, traveling at a speed of 300,000 km per second like the speed of light. These frequencies represent the number of cycles per second and use short-waves as the short window. The power we use is 60 mW, which changes the polarity of + and-60 times per second and propagates in the air.

As shown in FIG. 1, the electromagnetic wave forms a right angle between E representing an electric field and H representing a magnetic field, respectively. The wavelength is the distance from the maximum value of the electromagnetic wave to the next maximum value. The light bulbs we use are actually stronger and weaker by changing their polarity 60 times per second, but they are not able to detect the intensity of light due to the afterimages on the human retina. Korea, Japan, and the United States used 60 kW of electricity, while in Europe, they used 50 kW of electricity.

Electromagnetic waves have infinite kinds and shapes according to strength, waveform, etc. as well as frequency. The higher the frequency, the shorter the wavelength and the energy of the electromagnetic wave increases.

In general, microwave ovens used in homes apply a microwave of high energy at 2450 MHz to food to heat the water molecules contained in the food to heat the food. In addition, since the bond phone also uses a microwave of 800 ~ 900MHz, electromagnetic waves transmitted from the antenna is propagated into the brain, which is a problem by raising the temperature of the cell. Light rays are also classified as infrared rays, visible rays, and ultraviolet rays. Among them, the wavelength of ultraviolet rays is the shortest, which is known to cause skin cancer. DC to ultraviolet rays are called non-electromagnetic waves and X and gamma rays with shorter wavelengths than ultraviolet rays are called ionizing radiation. The radiation has a very strong energy that can penetrate the body and cause abnormalities in the molecules of the cell, which can cause abnormalities in the genetic factor.

Electric and magnetic fields occur in nature and in all living things and are one of nature's fundamental forces, such as gravity. The molecules that make up our bodies, or all living or inanimate objects, have electric fields, and the messages transmitted within our nervous system generate electric and magnetic fields.

Power plants, power lines in buildings, and all plugged electrical appliances generate electric and magnetic fields of 60 kHz at the power source frequency. The strength of this 60-kV electromagnetic field can be measured with a special instrument called an electric field meter or a Gaussian meter. The unit of the electromagnetic field is volts per meter, ie V / m. When the field strength is large, use thousands of volts per meter and kilo-volts per meter (KV / m) in larger units. The units of strength of the magnetic field are gauss and Tesla. Gaussian (G) is a very large unit, so it uses a lot of mG, which is 1/1000 of 1G, and Tesla (T) is also a very large unit, which corresponds to 10,000G, which also uses μT, which is 1 / 1,000,000 of 1T.

Both electric and magnetic fields are formed by electric charges. Positive and negative charges exist in nature and in all electrical things, attracting positive and negative charges. Two positive charges are pushed in opposite directions, and two negative charges push each other like two positive charges. The charges are negative particles and there are many electrons in one atom.

All electric charges are surrounded by an electric field and each electric charge is driven by an electric field. The total charge of an object determines the voltage of the object. Generally, the higher the voltage of an object, the more charge it carries. Each charge forms its own electric field and each of these fields adds up and acts as a single field: high-voltage objects form stronger electric fields because objects at higher voltages carry more charge.

On the other hand, when the charges move, that is, when the current flows, the charges exert a force on each other. This force forms a magnetic field and acts through space. Magnetic fields are the forces that a moving charge exerts on other moving charges because of their movement, and are not created by non-moving charges.

The group of charges moving in the same direction is called current, and the more the charges moving, the larger the current, and the magnitude is expressed in amperes (A). All currents generate a magnetic field, and larger currents create a stronger magnetic field. The magnetic field only exerts force on moving charges, or currents, not on stationary charges.

As the intensity of electric and magnetic fields decreases from a candle or a stove, light and heat weaken, and as the electromagnetic waves move away from a source, they rapidly decrease. For example, the 3500 mG magnetic field generated by an electric shaver decreases rapidly to 150, 22, 6.7, 2.6 and 1.5 mG at 15, 30, 45, 60 and 90 cm apart, respectively.

As shown in FIG. 2, the intensity of the 60 Hz electric field and the magnetic field in a 500 kV high voltage line, an electric blanket, an electric shaver, a toaster, a distribution line, a living room, and the like are variously represented as shown by a bar graph. Since the electric field strength is determined by the voltage of the electromagnetic wave source, the high voltage line generates a stronger electric field than the low voltage line, but the electric field strength in the human body may appear larger than the high voltage line with the shortest distance from the source.

The electric field is electric charge, so if no current flows, no magnetic field is generated, but an electric field is generated. Therefore, even if the toaster or electric blanket is not working, an electric field may be generated when it is connected to an outlet. In the United States, there are three outlet plugs, or two plugs with long ones and shorter ones. In this case, when the power switch is turned off, no electric field is generated from the appliance, even if the cord is connected to the outlet. However, when two plugs are the same length as in Korea, even if the power switch is turned off, an electric field may be generated since the 100V wire remains and the ground wire is broken.

Since the strength of the magnetic field is proportional to the magnitude of the current flowing through the electromagnetic wave generating source, even if the same high voltage line is required for power, the magnetic field strength increases when a lot of current flows. In general, the transmission line in the residential area is hot in the early evening when the lights are turned on or the weather is hot, so the electric current increases when the air conditioner is used a lot.

Not all electrical appliances that use high power generate strong electric fields. For example, a device such as a transformer or a motor for high power is designed so that electric and magnetic fields are generated only within the device, so that the electric and magnetic fields are weak outside the device. Leak out from the motor.

If we think about where we usually spend time in our daily lives, there are usually two or three places, especially where we spend a lot of time in our bedrooms. In recent years, people looking for convenience in the living room use a heater, an electric blanket or an electric bed to avoid the cold. When the heater, the electric blanket or an electric bed is old, they generate a strong magnetic field as high voltage line. In some cases, if the electrical appliances are to be used, it is necessary to raise the temperature in advance before going to bed, and then turn off the power and unplug in advance.

On the other hand, the electric bed is used for heat transfer to convert the electrical energy into thermal energy, and the heat transfer is divided into resistance heating, arc heating, induction heating or dielectric heating according to the method of generating. Resistance heating uses Joule heat, which generates heat when a current is passed through a resistor, such as thermoelectric. It is used in household appliances such as irons or heaters, electric furnaces, resistance welding machines, etc., and arc heating generates a voltage between two electrodes. It is used for arc welding machine or arc furnace. It is used for arc welding machine or arc furnace. Induction heating uses eddy current loss or hysteresis loss in the conductor by electromagnetic induction. It is used in furnaces and heat treatments, and dielectric heating uses heat generated by dielectric damage different from Joule's heat when a dielectric (insulator) is placed on a high frequency electric field.

As the heat transfer material for generating the heat transfer, a heating element is mainly used, and the heating element includes a metal heating element and a non-metal heating element. The heating element should have high melting point, good resistance to high temperature, excellent corrosion resistance, moderate resistance, low temperature coefficient of resistance (+), easy processing, low cost and abundant raw materials. It is necessary.

Nichrome wire or iron chromium wire is mostly used for the metal heating element, and the nichrome wire can withstand high temperatures of about 1100 ° C. and the iron chromium wire is inexpensive and is used instead of the nichrome wire. In addition, iron, nickel, platinum, tungsten, molybdenum and the like are used for special applications.

The non-metallic heating element is a carborundum (hydrocarbon) heating element, which is representative of the high temperature of about 1400 ℃, so it is frequently used at a high temperature of 1100 ℃ or more. The main component is silicon carbide (SiC), and various specific resistances can be obtained depending on the mixing ratio of carbon and silicon. However, there is a drawback that the installation of the terminal is difficult because it is difficult and flexible. In addition, the carbon heating element is a baked product made by adding a caking agent to the powder of carbon to form a rod or a teapot, and is used at 1000 to 3000 ° C, but evaporation and oxidation are severe when not sealed.

In addition, the heating wire is used in the form of a wire or a band, and as shown in FIG. 3, when the heating wire is corroded by gas or liquid, or when heating the liquid without passing current through the liquid, the resistance wire is insulated with mica. In addition, a space heater or a resistance wire 1 placed in the metal tube is insulated with powder such as lime, alumina or magnesium oxide 2, and a seed wire placed in the metal tube 3 is used.

However, since the conventional heating wire does not have a separate ground, electric waves are generated in the heating wire even when the power is not turned on, and when current flows in the heating wire, magnetic field is generated in proportion to the intensity of the current flowing in the heating wire. There was a problem that the electromagnetic wave is generated from the product adversely affecting the human body.

Thus, the present invention was devised to solve the above problems, and instead of the heating wire used in the prior art, by forming a heating wire with a carbon yarn heating element, far-infrared rays are emitted together in the process of dissipating heat from the heating wire, Wrap the conductor wire with Teflon coating which is a dielectric, and spun the carbon heating element which is an outer conductor on it, and then offset the magnetic field by applying a glass fiber braided silicon coating and silicon coating to protect the carbon heating element. The purpose of the present invention is to manufacture a non-magnetic heating wire which does not generate magnetic fields and electric fields by transversing aluminum foil or braiding copper wires to earth.

* Explanation of symbols for main parts of the drawings

DESCRIPTION OF SYMBOLS 1: Resistance wire 2: Magnesium oxide 3: Metal tube 11: Conductor wire 12: Teflon coating 13: Carbon yarn heating element 14: Glass fiber braided silicon coating 15: Silicone cloth 16: Aluminum foil or copper braid

The present invention for achieving the above object is to wrap the conductor wire provided in the center with Teflon coating of the dielectric, the carbon fiber heating element of the conductor and then spliced on the glass fiber braided silicon coating to protect the carbon fiber heating element The silicon coating is used to offset the magnetic field, and the silicon foil is coated on the silicon coating so as to protect the heating wire from external contaminants after the aluminum foil is rolled up or the copper wire is braided and grounded.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 4 and 5, a conductor wire 11, which is an internal conductor for conducting electricity, is provided at the center of the heating wire, and the conductor wire 11 is wrapped with a Teflon coating 12, which is a dielectric (insulator). W. On the Teflon coating 12, a carbon yarn heating element 13 made of a combination of thin carbon fibers is plyed together, and the carbon yarn heating element 13 is an electric conductor.

Since the carbon yarn heating element 13 is thin and weak, a glass fiber braided silicon coating 14 is disposed thereon to protect it from external physical forces, and the glass fiber braided silicon coating 14 is protected from an external contaminant on the glass fiber braided silicon coating 14. The silicon sheath 15 is covered.

In addition, the aluminum foil 16 is transversely wound (wound) or the copper wire 16 is braided on the silicon sheath 15 to ground the electric wave, and the silicon sheath 15 is again covered thereon. The aluminum foil or copper wire 16 is grounded.

In the above, the external magnetic fields of the carbon yarn heating element 13 are offset to each other to be '0'. Since the aluminum foil or the copper wire 16 is grounded, the electric field is also absorbed by the earth, so the magnetic field and the electric field emitted from the heating wire are '0'. Becomes

Thus, the process of the magnetic field and the electric field becomes '0' in detail is as follows.

Generally used to find the magnetic field is Ampere's circuital law, which can be derived from the Bio-savart's law of obtaining the micro magnetic field for a microcurrent.

According to Ampere's Law of Rounding, the integral of H (intensity of magnetic field) for a closed curve is equal to the current enclosed by that path. Here, the sign of the current coinciding with the direction in which the screw travels is positive when the direction of the current is turned in the direction of the closed curve through which the load is distributed, and the opposite current becomes negative.

As shown in Fig. 6, the direct current ((AC current is the same as the result of the current is used to simplify the calculation.) For the circular lead through which I flows, the loading of H for closed curves a and b is It becomes I, but the loading of H for closed curve c through the conductor is less than I, and exactly equal to the current surrounded by curve c. The shipments for curves a and b are the same, but the integral function is of course different. To calculate this integral, one point on the integral path is multiplied by the integral path direction component of H and the length of the microincrement at that point, and the next increment is repeated until the integral path is rounded.

Applying Gauss's law yields the total amount of charge in a closed curve, the ampere's law can be used to calculate the total current surrounded by a closed curve.

Applying the above-described ampere law to the present invention, the following process is performed.

As shown in FIG. 7, 'I (A)' flows through the conductor wire 11, which is an inner conductor, and '-I (A)' flows through the carbon yarn heating element 13, which is an outer conductor, and the conductor wire, which is the inner conductor ( 11) and the carbon yarn heating element 13, which is an outer conductor, are assumed to be infinitely long coaxial transmission paths.

We use cylindrical coordinates to simplify the calculation, and from symmetry we see that H is not a function of ψ and z.

The line current does not generate the z component of H, and the Hρ component of the magnetic field generated at ψ = 0 by the line current at ρ = ρ ₁ , ψ = ψ ₁ is at ρ = ρ ₁ , ψ = -ψ ₁ Canceled by line current. This symmetric relationship is shown in FIG. 8, and it is understood that only the Hψ component varies according to ρ.

The magnetic field is as follows for a circular integrator having a radius ρ larger than the radius a of the inner conductor and smaller than the inner radius b of the carbon yarn heating element 13 that is the outer conductor.

(a <ρ <b)

Also, if ρ is smaller than the radius of the inner conductor, the current I 'surrounded by the closed curve is

Because of (ρ <a)

If the integration path is inside the carbon yarn heating element 13, which is an outer conductor,

(b <ρ <c)

Finally, when ρ is larger than the outer radius c of the carbon yarn heating element 13 that is the outer conductor, the current surrounded by the closed curve becomes zero. H _φ = 0 (ρ <c).

In other words, the external magnetic field becomes zero. This is because + current and-current are surrounded by an integrator. At this time, since the magnetic fields generated in each current are completely canceled with each other, this is an example of shielding because coaxial cables carrying large currents have little effect on other circuits in close proximity.

In addition, the aluminum foil 16 is transversely wound or the copper wire 16 is formed on the silicon coating 15 which protects the outer conductor carbon yarn heating element 13 and the glass fiber braided silicon coating 14 from external contaminants. Although braided, when the aluminum foil 16 or the copper wire 16 is grounded, the electric field waves generated by the carbon yarn heating element 13 are absorbed through the earth so that the electric field waves do not come out of the heating wire.

As described above, in the manufacture of non-electromagnetic heating wire according to the present invention is composed of a carbon heating element (13) instead of the heating wire used in the prior art by the far infrared rays are emitted together in the process of heat is emitted from the heating wire, the conductor provided in the center The line 11 is wrapped with a teflon coating 12, which is a dielectric material, and the carbon yarn heating element 13, which is an outer conductor, is spliced thereon, and then the glass fiber braided silicon coating 14 is used to protect the carbon yarn heating element 13. The silicon sheath 15 is used to offset the magnetic field, and the heating wire which does not generate the magnetic field and the electric field is generated by transversely winding the aluminum foil 16 on the silicon sheath 15 or braiding the copper wire 16 to ground. Simultaneously with the production, the far-infrared rays are released together during the heat generation from the carbon yarn heating element 13, which has a beneficial effect on the human body.
