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 control knob for an appliance deploys a round bezel region that surround a fixed electronic display panel that is touch sensitive. The appliance state or operating condition is modified by the user rotating the bezel and selecting graphic user interface (GUI) icons on the electronic display. The bezel orientation modifies the GUI to display icons that operate the appliance in different modes. In a first mode of power control, the GUI displays power levels and the bezel orientation modifies the power level. In a second mode, the GUI displays temperature settings and the bezel orientation modifies the temperature. The GUI displays icons that when activated switch between the first and second mode as well as turn off the appliance. Another icon may activate a third mode that enables control and display of other settings, such as temperature units, time and date, count down timers and the like.

A cooking apparatus is provided. The cooking apparatus includes heating coils, an input apparatus receiving input of output levels for each of the heating coils, inverters providing driving power to each of the heating coils separately, and a processor controlling the inverters based on the inputted output levels. The processor is configured to predict the power consumption of each of the heating coils based on the inputted output levels, and based on the sum of the predicted power consumption being greater than a predetermined power value, determine a subject heating coil based on the predicted power consumption for each heating coil and history information on power adjustment of the heating coils, and control an inverter corresponding to the subject heating coil such that the subject heating coil operates at a smaller output level than a current output level.

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 device is disclosed. The induction device comprises: a main body having a heater; a knob attachable/detachable to/from a knob region provided on one surface of the main body; a touch sensor unit formed around the knob region and, if the knob is attached thereto, touching a protruding part provided at a lower side of the knob; and a control unit for adjusting the temperature of the heater by determining the rotation degree of the knob according to a touch position touched by the protruding part if the knob rotates in a state in which the knob is attached to the knob region.

An induction heating device includes a first coil that is wound about an axis by a first number of rotations, a second coil that is spaced apart from the first coil in a radial direction and that is disposed radially outward of the first coil, the second coil being wound about the axis by a second number of rotations, and a power supply unit configured to convert alternating current (AC) power and to supply a high-frequency AC to the first coil and to the second coil based on conversion of the AC power. The induction heating device is configured to output a maximum output level in a range from 6500 W to 7500 W based on a ratio between the first number of rotations and the second number of rotations.
