Definitions

  • the present invention relates to a system and method for the operation of an induction heater cooker.
  • an induction heating cooker operates based on the process of heating a ferromagnetic material by electromagnetic induction where eddy currents are to be induced and resistance provides heat dissipation within the ferromagnetic material, i.e. a cooking vessel in the form of a pot or pan.
  • induction heating By induction heating, high-frequency alternating current is passed through a coil upon which a magnetic field of the same frequency is induced.
  • the internal resistance of the pan causes heat dissipation due to Joule effect and energy transfer is interrupted once the pan is removed from the cooktop.
  • the energy efficiency of induction heating cookers is considerably high since there is no transfer of heat energy between the hob and the cookware and heat energy lost in the air is minimal.
  • a resonant converter in an induction heater circuit topology typically consists of a capacitor, an inductor and resistance. To this end, when power is supplied to the resonant tank, electric energy is stored in the inductor and transferred to the capacitor. Resonance therefore occurs while the inductor and the capacitor involve in energy exchange.
  • the resonant converter can be a half-bridge series resonant converter or a quasi-resonant converter.
  • a quasi-resonant converter exhibits certain advantages over a half-bridge series resonant converter especially due to its simpler circuit design having only one power switching device compared to the half-bridge series resonant converter whose overall operation is more complex.
  • the circuit design parameters in a quasi-resonant converter are regarded as a serious cost advantage in this regard.
  • a high-frequency power switch such as an IGBT is accordingly used.

  • the present invention provides a plurality of distinct induction coils driven by respective resonant inverters such that a plurality of flexible cooking zones can be created with a minimal number of induction coils whereby a cooking container of any size can be heated by induction heating.
  • the present invention is devised under the recognition that a significantly simple and immediately practical method of operating an induction heating cooker remains a great need because induction heating cookers are reported to be generally used by younger people having a certain inclination towards non- traditional technologies such as induction cooking.
  • the present invention provides a graphic display demonstrating graphic representation of different-size cooking containers and enables configuration of the cooking zones in an intuitively efficient manner without a touch interaction graphic display, to be operable by older people.
  • Touch screen user interfaces beside the fact that they have a role in increasing costs, are viewed more complex to be operated by older people. Apart from this, the cooking environment may have a negative impact on the performance of the touch screen due to humidity and vapor density. To this end, the invention is devised under the recognition that older or technology-averse people should also be able to immediately implement the method of the invention.
  • the present invention provides a system and method for the operation of an induction heating cooker enabling configuration of the cooking zones in an intuitively efficient manner without making use of a touch control user interface as provided by the characterizing features defined in Claim 1.
  • Primary object of the present invention is to provide a system and method for the operation of an induction heating cooker by which flexible cooking zones are configurable on a graphic display in an intuitively efficient manner without using a touch screen display.
  • the present invention proposes a system and method for operating an induction heating cooker by which presence of at least one cooking pan is detected and a corresponding graphic representation is generated on a graphic display.
  • a plurality of flexible cooking zones can be created with a minimal number of induction coils whereby a cooking container of any standard size can be heated.
  • a plurality of graphic zone indicators is provided such that each zone indicator is individually associatable with different cooking zones and a control button near the zone indicator effects selection of said zone.

  • a power circuit in relation with each induction coil (2) provides that heat energy is induced within a magnetically responsive cooking container or pan (6) placed above the induction coils (2) of the induction heating cooker (1).
  • the induction heating cooker (1) may comprise a plurality of induction resonant inverters (4) supplied with a source of AC voltage.
  • a full-wave bridge rectifier may be connected between the AC source and power stage of the resonant inductor.
  • the resonant inductor is conventionally connected between the output of said rectifier and the power switch.
  • the resonant capacitor is parallel to the resonant inductor and an anti-parallel diode, i.e. a freewheeling diode is connected parallel to the power switch.
  • the induction resonant inverters (4) of the induction heating cooker (1) may conventionally comprise AC signal filtering circuits. Power passing through a levelling capacitor together with filtering inductor serves to the purpose of filtering high frequency current. The voltage of the levelling capacitor is converted into a square wave by the high-frequency power switch. According to Ampere's Law, the square wave provides resonance creating a magnetic field around the resonant inductor, that is, the respective induction coil (2). The resonant capacitor provided in parallel with the resonant inductor therefore compensates the inductive nature of the latter.
  • the quasi-resonant converter's power switch may be an insulated gate bipolar transistor (IGBT) driven by a power switch driving circuit (5).
  • IGBT insulated gate bipolar transistor
  • the operating principle of the quasi-resonant converter typically relies on the storage of energy in the resonant inductor when the power switch is turned on, and transfer of energy from the resonant inductor to a cooking pan (6) when the power switching device is turned off.
  • a pan detection circuit (8) sensing cookware positioning is used.
  • Such a pan detection circuit (8) can monitor the resonant current or the IGBT voltage.
  • An electronic circuit that generates an output at the moment which the freewheeling diode starts conduction can be used.
  • a charge detection circuit therefore detects the zero-cross of the current of the freewheeling diode.
