The present invention eliminates the need for a separate harmful electromagnetic wave shielding means by using a heating line in which electromagnetic fields are canceled, and wireless control of a heat transfer mat to enable convenient control of the heat transfer mat using an infrared beam or a wireless remote control for radio wave (RF) transmission and reception. Relates to a device.

In general, electric charges create an electric field in space, and moving charges, that is, electric currents, create an electric field surrounding it.

When a current flows through the conductor, a magnetic field is formed around the conductor, and when the current has a specific frequency, an alternating electric magnetic field is formed. At this time, the higher the charge, the larger the electric field, and the more the current flows, the larger the magnetic field. The magnetic field (electromagnetic wave) and the electric field (electromagnetic wave) which change in intensity periodically Propagation through this space is called electromagnetic waves.

Therefore, when an alternating current flows through the conductor, electromagnetic waves of a power source frequency (50/60 Hz) are naturally generated, and the electromagnetic waves stimulate and damage many places of the human body.

The most effective way to remove the above electric field is to surround the electric field generating source (conductor, heat mat, heat insulation, various electric equipment, etc.) with a conductor and completely shield it, and then connect the conductor to the earth and the electric field induced by the conductor is grounded. The most effective way to remove the magnetic field is to completely shield the magnetic field source with a high permeability metal to shield the magnetic field from being released to the outside.

And, if the heating wire is distributed over a large area like the heating mat, there is a method of completely wrapping the entire heating mat with a conductor to remove the electric field, and a method of completely wrapping the whole heating mat with a high permeability metal to remove the magnetic field. It is not realistic because of the high cost in terms of economy.

On the other hand, in order to solve the above problems, the sensor winding wound on the outer peripheral surface of the winding core to act as a temperature sensor, the heating winding reciprocating in the opposite direction to the sensor winding outer peripheral surface to generate heat, and wound around the heating winding outer peripheral surface 2003 is a "heating wire having electric magnetic field shielding and offset function" which is composed of a shielding winding and a plurality of insulating members to maintain insulation between each winding to effectively shield and cancel the electric and magnetic fields generated from the heating winding. 7. 16.
