Abstract:
1. A method for controlling a cooking process in a cooking appliance, the cooking appliance including a cooking chamber, at least one sensor for detecting a gas concentration in the cooking chamber, and an electrical controller having an evaluation circuit with a timer and a memory and being in signal communication with the sensor, the memory having stored therein a plurality of sets of reference values, each of the sets of reference values corresponding to a respective shape of a reference function from a starting time t 0 to a respective ending time t Z of a reference cooking process, respective sets of parameters for the electrical controller being associated with the sets of reference values, the method comprising the steps in sequence: a) determining, in the evaluation circuit, from a gas concentration detected during the cooking process, a set of function values corresponding to a shape of a function that depends on the gas concentration from a starting time t b) generating, in the evaluation circuit, from the sets of reference values, respective sets of comparison values for a comparison at the time t c) comparing, in the evaluation circuit, the set of function values to the respective sets of comparison values; d) automatically selecting, using the evaluation circuit, a plurality of the sets of comparison values coming closest to the set of function values, and generating, using an algorithm, from the respective sets of parameters associated with the respective sets of reference values associated with the selected sets of comparison values, a selected set of parameters including at least an ending time of the cooking process, and using the selected set of parameters for the electrical controller until a next comparison is made at a time t e) repeating steps a)-d) until the ending time of the cooking process has been reached.
