Abstract (en)
[origin: EP2914060A1] An induction heating device includes a top plate on which an object to be heated is placed, a plurality of heating coils which are disposed below the top plate, an inverter which supplies a high frequency current to the plurality of heating coils, a control unit which controls an output of the inverter, an operation display unit which outputs an operation command to the control unit, and a detection unit for the object to be heated which detects whether the object to be heated is present on the top plate. The control unit controls the inverter to supply a detection current for detecting presence of the object to be heated to the plurality of heating coils prior to receiving an operation command signal for indicating a start of a heating operation from the operation display unit. The detection unit for the object to be heated detects the presence of the object to be heated from an input current and/or an output voltage in an electrically conductive path for electric power transmission from a power source to the heating coils, during a detection time period which the detection current is supplied to the heating coils.
