An induction cooker includes a microcrystal panel and at least three temperature sensors scattered on a bottom surface of the microcrystal panel, and the induction cooker is configured to heat a container to be measured. The method includes: obtaining temperature data collected by the at least three temperature sensors and position data of each temperature sensor relative to the microcrystal panel; obtaining an actual position of the container on the microcrystal panel according to the temperature data and the position data; obtaining a preset temperature curve matching the induction cooker according to the temperature data, and extracting a peak value of the preset temperature curve; and calculating an actual temperature of the container to be measured according to the actual position and the peak value.

Disclosed herein is a cooking appliance. A working coil is provided at a lower portion of the cooking appliance. The working coil heats a tray disposed in a cooking compartment in an IH mode. A receiver coil wirelessly receiving external power is stacked below the working coil. An electromagnetic shielding plate is installed between the working coil and the receiver coil to partition a space in which the two coils are installed. The electromagnetic shielding plate shields an electromagnetic field or electromagnetic waves such that the electromagnetic field or electromagnetic waves in one of the two partitioned spaces does not leak to the other space located across the electromagnetic shielding plate.

An induction hob device includes at least one induction heating element adapted to heat a cooking utensil, and at least one detection circuit which cooperates with the at least one induction heating element to detect a presence of the cooking utensil. The at least one detection circuit is hereby directly connected to the at least one induction heating element irrespective of an operating state.

A cooking system includes a hot plate having a region for setting down of a cooking pot, and a display unit arranged at least partially in a region close to the region for setting down a cooking pot, when being viewed in a vertical direction onto a main extension plane of the hot plate. The display unit is operated in an operating state by a control unit as a function of at least one operation request parameter.

An induction heating and wireless power transmitting apparatus includes: a first working coil portion including first and second working coils that are connected in parallel; a first inverter unit configured to apply a resonant current to the first working coil and the second working coil by performing a switching operation; a first semiconductor switch connected to the first working coil and configured to turn the first working coil on or off; a second semiconductor switch connected to the second working coil and configured to turn the second working coil on or off; and a control unit for configured to detect whether an object is positioned above the first working coil or the second working coil based on controlling the first and second semiconductor switches and the first inverter unit.

An induction heating device includes: a base plate; a working coil disposed vertically above the base plate, the working coil including a conducting wire that is annularly wound; a ferrite core that is disposed on an upper surface of the base plate, that is disposed vertically below the working coil, and that is configured to direct upward an alternating magnetic field generated by the working coil; and an insulating member attached to an outer portion of the ferrite core and configured to electrically insulate the working coil from the base plate.

An induction heating device includes a case having a lower plate that defines an inlet and an exhaust slit; a cover plate coupled to the case; a working coil disposed inside the case; an indicator substrate support coupled to the lower plate and disposed below the working coil; an inverter substrate disposed on a lower surface of the indicator substrate support and including an inverter and a first heat sink configured to dissipate heat generated from the inverter; and a first blowing fan disposed at the lower plate and configured to draw air from an outside of the case through the inlet and discharge the air to the inverter substrate. The exhaust slit is configured to discharge, to an area below the lower plate, at least a portion of air discharged from the first blowing fan to the inverter substrate.

A stovetop device includes a heating area adapted to heat cookware placed thereon and/or food to be cooked thereon, and a control unit configured to operate at least one subarea of the heating area in at least one operating state as at least one target temperature burner and to assign different target temperatures to different positions of the at least one target temperature burner.
