COIL CONDUCTOR, INDUCTION-HEATING COIL, AND INDUCTION-HEATING COOKING OVEN

摘要

PPROBLEM TO BE SOLVED: To provide a coil conductor and an induction-heating coil ensuring stable insulating properties even with high frequency current applied thereto, and an induction-heating device with the induction heating coil. PSOLUTION: The coil conductor 4 is formed by providing an insulating layer 9 on an outer periphery of an assembly formed by stranding together a plurality of fine strands 8 to form an original assembling wire 10, stranding together a plurality of the original assembling wires to form a first assembling wire 1, stranding together a plurality of the first assembling wires to form a second assembling wire 2, stranding together a plurality of second assembling wires to form a third assembling wire 3 and forming an insulating layer 20 on an outer periphery thereof. The insulating layer 20 is formed by winding a tape-shaped thermosetting resin 21 coated with a low-melting point fluorine resin 22 on one surface or both surfaces thereof round the third assembling wire 3. The induction-heating coil is formed by winding up the coil conductor 4. The induction-heating device is provided with the conduction-heating coil so formed. PCOPYRIGHT: (C)2009,JPO&INPIT
