A cooking vessel sensor and an induction heating device including a cooking vessel sensor is provided. The cooking vessel sensor may include a cylindrical hollow body having a first receiving space defined therein; a hollow cylindrical magnetic core received in the first space and having a second receiving space defined therein; and a sensing coil wound on an outer face of the side wall by a predetermined number of winding counts. The cylindrical hollow body may have a side wall having a coil outlet defined therein, and the sensing coil may pass though the coil outlet out of the body. The cooking vessel sensor may further include a controller that applies a current to the sensing coil and determines, based on a sensing result of the cooking vessel sensor, whether the cooking vessel is inductive or has an inductive heating property.

An induction heating device and a method for sensing a cooking vessel on an induction heating device are provided. The induction heating device may include a controller that converts a resonance waveform generated as current is applied to a sensing coil into a square waveform. The controller may determine whether a cooking vessel placed on the induction heating device has an inductive heating property based on a number of pulses of the converted square waveform.

A cooking device safety system includes a stovetop cooking device with a first sensor to detect the presence of an object on or adjacent to a burner; a second sensor to detect a condition of the burner; a transceiver to send a signal from the first and/or the second sensor to a remote device; a microcontroller with a timer; and a signal output device. A method for providing a safe cooking device environment includes detecting a status of a cooking device and detecting the presence of an object on or in the cooking device. When the cooking device has an activated status and an object is detected, the system detects whether a threshold cooking time has been exceeded. If the threshold has been exceeded, the system produces an alert via a signal output device; and/or sends an alert to a remote device; and/or inactivates the cooking device.

A method controls an induction heating device that is configured to operate based on a multi-phase power supply and that includes a working coil configured to heat an object and a controller configured to detect the object. The method includes: receiving voltage information related to a first input voltage and a second input voltage that are supplied by the multi-phase power supply and that have different phases from each other; selecting a reference voltage among the first input voltage and the second input voltage based on the voltage information; determining a detection time point, which corresponds to a time instant at which a detection operation is to be performed for detecting the object on the working coil, based on the reference voltage; and performing the detection operation at the detection time point.
