<p><P>PROBLEM TO BE SOLVED: To prevent uncomfortable beat sounds for a user from occuring from a load such as a cooking pan during use of an induction heating cooker by interference caused on an inverter circuit and a heating coil by switching noises generated at a switching power supply. <P>SOLUTION: This induction-heating cooker is provided with the body unit 6 having a heating coil 1, a rectifying circuit 5, the inverter circuit 2 which is connected to the rectifying circuit 5 and which generates a high-frequency current in the heating coil 1, and a control circuit 8 for controlling heating by the heating coil 1, and with a sub-unit 7 having the switching power supply 3 for supplying a DC constant voltage to the control circuit 8, a first noise filter 4a connected between a commercial power supply 13 and the rectifying circuit 5, and a second noise filter 4b connected between the commercial power supply 13 and the switching power supply 3. The main body unit cabinet 11 to constitute the body unit 6 is constituted of a conductive magnetic body to prevent noise interference between the body unit 6 and the sub-unit 7. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
