A cooktop appliance apparatus for use in cooking includes a controller for controlling operation of the fan system based on an average power level supplied to a heating system, and based on a temperature measure associated with one or more subsystems. The appliance includes a hardware-implemented safety module having two or more temperature actuated safety circuits. The appliance includes a user interface adapted to receive a user input with respect to operating parameters of the heating system, the user input including a heating control mode and a set temperature. The appliance includes a controller adapted to identify a cooking vessel on an induction cooktop.

An apparatus comprises at least two cooking devices, a control unit, an input device and an output device. The control unit is adapted to determine if at least two of the foodstuffs to be cooked can be cooked in one of the cooking devices in an at least partly concurrent manner. Depending thereon, the control unit allocates the foodstuffs to be cooked to the cooking devices and outputs, via the output device, which of the foodstuffs can be cooked in which cooking device or in which cooking devices.

An induction heating type cooktop includes a case, a cover plate that is connected to an upper end of the case and that has an upper surface configured to support an object to be heated, a working coil disposed inside the case, a thin layer disposed at the cover plate and configured to be heated by the working coil through induction, and a working coil cooling fan configured to blow air toward the working coil.

A heat retentive server includes a chamber defined between an upper shell and a lower shell that are connected to one another. An induction-heatable member is positioned in the chamber, and the induction-heatable member may be heated by electromagnetic induction to a first temperature that is greater than the heat deflection temperature of the upper shell. Buffering material is positioned in the chamber between the induction-heatable member and the upper shell, and the buffering material is adapted for providing predetermined conductive heat transfer from the induction-heatable member to the upper shell so that at least a portion of the upper shell is heated to a second temperature that is greater than the heat deflection temperature of the upper shell. The second temperature is less than the first temperature.

The present disclosure provides an induction cooking device for heating a cooking vessel. The induction cooking device comprises a cooking surface comprising a cooking hob, an induction coil, a driving circuit electrically coupled to the induction coil, and a coil mount that is arranged under cooking hob. The induction coil is arranged on the coil mount and the coil mount is configured to dynamically adapt the distance between the induction coil and the cooking surface based on a temperature of the induction coil and/or at least a component of the driving circuit. The coil mount is configured to increase the distance between the induction coil and the cooking surface with increasing temperature of the induction coil and/or the at least one component of the driving circuit. Further, the present invention provides a respective method.

A cooking assembly or method of operating the same may include features for receiving an image signal from a camera assembly of a cooking zone; identifying a cookware item based on the received image signal; and initiating, automatically, care information according to the identified cookware.

A method for controlling an induction heating apparatus of one embodiment comprises starting to heat a container, obtaining an inductance value of the container, calculating an overheating determination index based on the inductance value, comparing the overheating determination index with a predetermined first reference value, and determining whether to stop heating the container based on results of the comparison between the overheating determination index and the first reference value.

An induction heating vessel, including an interior wall formed of a first material, an exterior wall formed of a second material, where the second material is different from the first material, and the second material is less magnetic than the first material, and a thermally insulating barrier between the interior wall and the exterior wall.

A method for sensing a container includes: charging an induction heating circuit; sensing a current applied to the induction heating circuit, converting a current value of the current into a first voltage value; comparing the first voltage value with a resonance reference value; generating a resonance of the current; sensing a resonant current generated in the induction heating circuit; converting the resonant current into a second voltage value; comparing the second voltage value with a count reference value; generating one or more output pulses; comparing a count of the one or more output pulses with a reference count, or comparing an on-duty time of the one or more output pulses with a reference time; and based on (i) the comparison of the count with the reference count or (ii) the comparison of the on-duty time with the reference time, determining whether an object is present on a working coil.
