PROBLEM TO BE SOLVED: To solve a problem wherein a conventional induction heating cooker has substrates composing two inverter circuits to drive two induction heating coils, two sets of cooling devices to cool them are required, thereby causing resonance by two fans to generate roaring sound and loud noise. SOLUTION: This induction heating cooker is provided with a plurality of the induction heating coils 3, a plurality of the substrates 8 to drive them, a fan 10 to cool the substrates, and a motor 12 to drive the fan 10, and is structured so as to cool the substrates by superposing them in a multistage shape. Since cool air can be sent to a plurality of the substrates with one fan, and cool air hits every substrate, they can be efficiently cooled. COPYRIGHT: (C)2004,JPO |
