<p><P>PROBLEM TO BE SOLVED: To prevent rush current from flowing into an inverter means and realize zero standby power. <P>SOLUTION: The device is provided with: an inverter means 4 driving a heating coil 4a; a second control means 3 controlling the inverter means by receiving control information of the first control means 2; a first switching means 6 putting on/off power source of the first control means 2; a second switching means 7 connected in parallel with the same; a third switching means 8 putting on/off power source of the second control means 3; a fourth switching means 9 putting on/off power supply of the inverter means 4; and a current restraining element 10 connecting a load side of the third switching means 8 and a load side of the fourth switching means 9. The first control means 2 starts up when the first switching means 6 is operated and turned on, turns on the third switching means 8 as well as the second switching means 7, and turns on the fourth switching means 9 in advance of beginning of passage of power to the heating coil 4a by the inverter means 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
