<p>Disclosed is a highly reliable induction cooker wherein false detection of boiling over from a cooking container when the cooking container is heated is significantly reduced. The induction cooker is provided with a boiling over detecting unit, which reduces heating power of an inverter to a previously set value, in the case where the change quantity of a capacitance with respect to a reference value is larger than a power reduction threshold value, said capacitance being detected by a capacitance detecting unit. During a boiling over determining period after the change quantity of the detected capacitance with respect to the reference value is increased to be larger than the power reduction threshold value, heating operation is stopped or heating power is reduced to a third set value, i.e., a value smaller than a second set value when the change rate of the detected capacitance is equivalent to or larger than a predetermined change rate, and when the change rate of the detected capacitance is smaller than the predetermined change rate, the heating power is maintained at the second set value.</p> |
