Abstract (en)

[origin: EP3331321A1] The induction-heating cooker (1) includes a drive unit (40) which supplies high-frequency current to an electromagnetic coil (100) for generating a magnetic field, and a detection unit (60) which detects load characteristics of a load placed on the electromagnetic coil (100) on the basis of electric characteristics regarding the drive unit (40). If the load is determined to be a heating target on the basis of a result of detection by the detection unit (60), the maximum output power value of the output range of the drive unit (40) is set in a first range and the electromagnetic coil (100) is operated as an induction heating coil. If the load is determined to be a power receiving subject, the maximum output power value of the output range of the drive unit (40) is set in a second range and the electromagnetic coil (100) is controlled as a power feed coil so as to supply power to the power receiving subject by electromagnetic induction. Thus, an appropriate amount of power can be efficiently supplied in accordance with the target load both when a heating target is inductively heated and when power is supplied to a power receiving subject.
