Definitions

  • the invention relates to a method for hob control, with a hob plate, in particular of glass ceramic, with at least one cooking zone, which is heated by means of an arranged in the installed position of the hob below the hob induction heating device with an electrical control unit with processing and memory and with below the cooking field plate in the region of a limited to the surroundings measuring spot arranged heat sensor units, wherein the first heat sensor unit substantially in the cooking zone alone of the hob plate and with the second and third heat sensor unit substantially in the cooking zone of the hob plate and a parked thereon Cookware downgoing outgoing heat flow is detected, as well as with a light source for performing a reflectance measurement via at least one heat sensor for determining the emissivity ⁇ cookware of the cookware tray on the stove top off cookware and a hob for performing the method.
  • Such a method is for example from the DE 10 2004 002 058 B3 known.
  • the known method controls a cooking process in a hob, with a hob plate, in particular glass ceramic, which has perpendicular to their Hauptausdehnungsraumen limited by a flat top and bottom material thickness s, with at least one cooking zone, by means of a in the installation position of the hob below the cooktop panel arranged heating device is heated, with an electrical control for controlling the heating power of the heater and arranged below the cooktop plate heat sensor units.
  • the known method proposes that with the first heat sensor unit essentially one in the region of the cooking zone alone of the hob plate and with the second and third heat sensor unit substantially a in the range of the cooking zone from the cooktop plate and a cookware set down therefrom outgoing heat flow is detected.
  • the heat sensor units are arranged on the underside of the hob plate in the region of a limited measuring spot, which is limited to the environment, for example by a measuring shaft or waveguide.
  • the cookware bottom temperature T cookware is determined and evaluated in the electrical control device with processing unit and memory for controlling or regulating the heating power of the heater.
  • the invention thus presents the problem of providing a method for hob control in which the cookware temperature, taking into account the influence of the emissivity of the cookware and the transmittance of the hob plate is determined as accurately as possible and evaluated for the hob control in terms of controlling the power of the induction heating.
  • the invention also raises the problem of providing a hob for carrying out the method according to the invention.
  • the achievable with the present invention consist in particular in the improved accuracy of the control of a cooking process in a hob. This is achieved by an improved accuracy of the determination of the actual on the cooker bottom and thus the cookware temperature T cookware , taking into account the influence of the emissivity of the cookware and the modified by contamination of the cooktop plate transmission coefficient.
  • the emissivity of the cookware for carrying out the method according to the invention is preferably detected metrologically via the second heat sensor unit by means of a reflection measurement of the light beam emanating from a light source and directed against the cookware bottom.
