INDUCTION HEATING COOKER

摘要

In this induction heating cooker, an inverter circuit (23) is driven corresponding to determination results obtained from a load determining means, and in a state wherein the drive frequency of the inverter circuit (23) is fixed, a change quantity of a value, which is obtained on the basis of a primary voltage value corresponding to an alternating current voltage from an alternating current power supply (21) or a direct current voltage of a direct current power supply circuit (22), and on the basis of a current value of an input current to the inverter circuit (23) and/or a coil current flowing in a heating coil (11a), is obtained per predetermined time. On the basis of the change quantity per predetermined time, a temperature change of a subject to be heated (5) is detected.
