ELECTRIC MAT WITH APPARATUS FOR PREVENTING ELECTROMAGNETIC WAVES AND A POWER SUPPLY APPARATUS THEREOF, CAPABLE OF EFFICIENTLY BLOCKING HARMFUL ELECTROMAGNETIC WAVE

摘要

PURPOSE: An electric mat with apparatus for preventing electromagnetic waves and a power supply apparatus thereof are provided to control a relay by intercepting power supplied to a heating element.;CONSTITUTION: A heating element(30) is connected to a first terminal. An electronic wave shielding unit(40) is serially connected to the heating element. The electronic wave shielding unit is connected to a second terminal. A relay(110) connects an AC power source to the first and second terminals. The MICOM(100) controls the operation of relay in order to connect first and second wires to the second to the first terminal and second terminals respectively. The electronic wave shielding unit is comprised of a wire which is wounded around the heating element and absorbs electromagnetic wave.;COPYRIGHT KIPO 2011
