Method for regulating a cooking process

摘要

The invention relates to a method for regulating a cooking process using an item of cookware having inductive properties on a cooking area, wherein a coil is arranged as part of an LC resonant circuit in the region of the cooking area and the natural frequency of the LC resonant circuit is measured repeatedly or continuously. The invention also relates to a cooking apparatus having at least one cooking area, a temperature sensor, a power controller, an LC resonant circuit having a coil, which is arranged in, around or in the region of the cooking area, and a controller, which is connected to the temperature sensor and a unit for measuring the frequency of the LC resonant circuit and which is programmed to carry out method, wherein the controller has access to a memory for storing the mathematically determined parameter function or vector function.

1. A method for regulating a cooking process using an item of cookware having inductive properties on a cooking area, wherein a coil is arranged as part of an LC resonant circuit in a region of the cooking area and a natural frequency of the LC resonant circuit is measured repeatedly or continuously, said method having the following method steps:
A) alternately heating the cooking area with at least two different target powers, wherein during this process a temperature at a bottom of the item of cookware is repeatedly or continuously measured using a temperature sensor to generate a measured temperature profile and said natural frequency of the LC resonant circuit is repeatedly or continuously measured; B) determining a parameter function or vector function from the measured temperature profile over time of the temperature sensor and from the frequency of the LC resonant circuit depending on the time and depending on the least two target powers; and C) conducting the cooking process depending on the parameter function or vector function determined in method step B) and depending on the frequency of the LC resonant circuit and/or the change over time of the frequency of the LC resonant circuit.
