Definitions

  • the present invention relates to an induction heating cooktop wherein it is detected whether or not the vessel placed thereon is at the appropriate position.
  • the induction heating cooktop functions according to the principle of heating a cast iron or steel ferromagnetic cookware, for example a pot, with the magnetic field effect generated by the induction coil.
  • SSQR single switch quasi-resonant
  • the single switch quasi-resonant circuits (SSQR) are preferred due to cost advantage; however, they operate in a narrower energy frequency range and can deliver power to the cookware only within a certain voltage and power range.
  • induction heating cooktops wherein the single switch quasi-resonant circuits (SSQR) are used, problems are encountered in detecting different kinds of cookware and the changes in position of the cookware on the cooktop burner. Furthermore, difficulties arise in detecting the position of the cookware in mains voltage fluctuations and at different temperature conditions.
  • multi coil - multi zone structure is used, heating can be maintained on the entire cooktop surface and flexibility is provided for the user. In this type of induction heating cooktops, induction coils of various shapes and sizes are situated on the cooktop surface.
  • the detection of the cookware position and furthermore the characteristic features like the diameter, type and the ferromagnetic properties during power transmittance to the cookware is quite critical for products wherein multi coil and also the single switch quasi-resonant circuits (SSQR) are used.
  • the position of the vessel placed on the induction coil is generally defined by circular border lines drawn on the cooktop surface. If aligned with the induction coil according to the predetermined border lines, the vessel can be heated efficiently. The user is allowed to slide the vessel outside the said border lines a little and the vessel can be heated at the desired power setting as long as it is in the efficient heating zone.
  • the vessel With the condition of being in the efficient heating zone, the vessel should be heated according to the power setting selected by the user and without being affected by variable mains voltage and temperature conditions and if the vessel is slid outside the efficient heating zone, this situated should be detected and energy transmitted to the vessel should be interrupted. If it is not detected that the vessel is slid outside the efficient heating zone, the vessel cannot be heated according to the selected power setting and the circuit board can be damaged.
  • the European Patent Application No. EP2282606 relates to an induction apparatus control method.
  • the presence or absence of the vessel on the induction coil, the resistivity and the dimensions thereof are detected by comparing the resonance voltage with a predetermined fixed reference voltage in the control unit.
  • JP2011023163 a rice cooker is explained wherein existence or nonexistence of a pan on the induction heater or whether or not the pan is located at a designated position is detected under unstable power source voltage conditions.
