PROBLEM TO BE SOLVED: To prevent two fans of the two cooling units used for cooling a board consituting two inverter circuits driving two induction heating coils from generating a resonance and a howling noise giving rise to a louder noise, and to prevent after-cooling hot air from hitting a user of the cooker or raising temperature of the inside of the cabinet which is a natural result of the necessity of exhausting air toward front or into the inside of a cabinet since each fan needs an air intake port is necessary, and further, to avoid a cost hike. SOLUTION: The induction heating cooker has a structure of a multistage stack of boards for cooling, with a plurality of induction heating coils 3, a plurality of boards 8 which drive the coils 3, a fan 10 cooling the base, and a motor 12 driving the fan 10. Cooling air can be sent by one fan to the plurality of the boards arrayed in parallel, so all the boards are hit by cooling air, and can be cooled effectively. |
