<p>PROBLEM TO BE SOLVED: To maintain heating output while preventing pot noise from being generated during a heat retaining operation.SOLUTION: A control part 7 sets first stable heating output during a rice cooking operation to be greater than stable heating output at which a resonance sound by a pot 1 and a resonance current is generated, and sets second stable heating output during a heat retaining operation to be smaller than heating output at which resonance sound is generated so as to achieve a rice cooker that can perform a cooking operation during a rice cooking operation with strong heating output, perform a heat retaining operation with the heating output that maintains the heat retaining temperature during a heat retaining operation, and keep a quiet environment where a resonance sound is not generated.</p> |
