ELECTROMAGNETIC-FIELD-SHIELDED HEATING WIRE OF HYPOCAUST TYPE IN WHICH FAR INFRARED RAY IS RADIATED

摘要

A hypocaust type electromagnetic-field-shielded heating wire radiating a far infrared ray is provided to offer a treatment function of the far infrared ray as well as warm keeping and fomentation effects by uniformly radiating the far infrared ray. A hypocaust type electromagnetic-field-shielded heating wire radiating a far infrared ray includes a core wire(10), a heater wire(20), a thread coating(30), an insulating inside skin(40), an electromagnetic field shielding member, a yellow soil impregnating fiber coating, and an insulating outside skin. The core wire consists of a thread. The heater wire is wired in an outside of the core wire. The thread coating forms a hypocaust type space by being placed on the heater wire in a length direction of a heating wire. The insulating inside skin is coated so as to cover the core wire including the heater wire and the thread coating. The electromagnetic field shielding member shields an electromagnetic field by being formed on an insulating paper. The yellow soil impregnating fiber coating consists of a fiber material impregnated by a yellow soil and is coated on the electromagnetic field shielding member. The insulating outside skin is formed on an outside of the yellow soil impregnating fiber coating.
