The present invention relates to an electromagnetic wave and a magnetic field shielding heating wire, and more particularly, it is installed in household appliances or industrial heating products using electricity, and protects users of the heating product from electromagnetic waves by blocking electromagnetic waves and magnetic fields generated when electric resistance heat is generated. In addition, the insulation is improved by the result of coating by any one of PVC and silicone materials, and the cost of using PVC and silicone materials that are inexpensive to overcome the cost increase due to the use of expensive Teflon and the productivity decrease due to hardening The present invention relates to an electromagnetic wave and a magnetic field shielding heating wire, which can reduce the productivity and increase productivity.

In general, electric heating is generated by resistance heating to obtain electric heat by passing electric current through heating wires, arc heating by passing electric current while arcs are generated, and electric current flowing through good conductors such as metal. Induction heating to obtain heat transfer, and the like.

In particular, the resistance heating as described above may be heated by direct resistance heating, which transmits an electric current to the object to be heated, heat radiation and thermal conduction generated when an electric current is applied to a non-metal heating element such as a metal resistance wire or silicon carbide by approaching the object to be heated. It can be divided into indirect resistance heating, which heats and heats water.

On the other hand, as a heat transfer apparatus using heat obtained by using indirect heating as described above, there are various such as electric rice cooker / electric heating apparatus / electric iron / electric stove.

In addition, in the case of using oil or gas as heating fuel, not only combustion efficiency is low but also harmful by combustion gas, but when using midnight electricity, energy utilization efficiency can be maximized. There is a trend that the use of heat transfer equipment using heating is spreading.

When heating by using the electrical energy as described above is provided with a heating wire to receive the electrical energy to convert to thermal energy, a heat transfer mechanism having a structure that can prevent a short circuit is used.

As described above, the heating wire provided in the heating device uses nichrome wire / iron chromium wire at a temperature of 1,000 ° C. or lower, silicon carbide / cantal wire at a higher temperature, and molybdenum silicide wire at 1,400 ° C. or higher.

In particular, in order to obtain electric heat for heating, the core wire made of a metal such as nichrome or iron chromium is generally coated and used, but it is known that harmful electromagnetic waves are generated from such heating wires, and to reduce harmful electromagnetic waves. Much research effort has been made on heating wires.

As part of this research effort, an electromagnetic shielding heating wire, as in Utility Registration No. 192649, has been proposed. As shown in FIG. 1, a heating element wire 2, a Teflon insulating layer 4, and an insulating tape ( 6), the aluminum tape layer 8, the braided layer 10, and the insulating layer 12 are covered and molded in this order.

Therefore, the aluminum tape layer 8 increases the breakdown voltage of the Teflon insulating layer 4 and absorbs electromagnetic waves generated by the heating element wires 2, but its effect is on the absorption and removal of harmful electromagnetic waves, which is a main purpose. It was only minor.

On the other hand, Utility Model Registration No. 233539 employing a carbon yarn known to generate the least electromagnetic waves as a heating wire is shown in Fig. 2, winding the outside of the multiple strands of carbon yarn 14 to the glass fiber chamber 16. The outer surface of the carbon yarn 14 and the glass fiber chamber 16 is covered with silicon 18, and the outer surface of the silicon 18 is covered with a glass fiber mesh 20, and the glass fiber network ( A plurality of copper wires 22 are simultaneously wound on the outside of the 20, and the glass fiber net 20 and the outside of the copper wire 22 are covered with silicon 24.

In addition, the carbon yarn 14 may be made of 2400 strands, the copper wire 22 may be made of three strands.

Utility Model Registration No. 233539 as described above employs carbon yarn 14, which is known to generate the least amount of electromagnetic waves, as a heating wire, and has a structure in which an insulated copper wire 22 is wound in a spiral form and insulated again. Therefore, the electromagnetic wave blocking effect can be expected to be improved slightly compared to the above mentioned registration proposals, but in addition to these factors, no means for blocking electromagnetic waves have been devised.

In addition, conventional conventional heating wires usually have a structure in which a non-resistive wire is wound on the outside in parallel, or a non-resistive wire, which is electrically connected to the outside of the heating wire arranged at the center, to block electromagnetic and electromagnetic waves emitted from the heating wire. The effect is minimal.

In addition, the Teflon applied in the manufacturing of the heating wire is expensive, difficult to handle, there is a problem that the manufacturing process is complicated. In addition, there is a problem that causes a cost increase as the insulating layer is formed using Teflon.
