Abstract (en)

[origin: EP1420613A2] The method involves monitoring the frequency of the alternating current for the inductive heating, which is affected by the cooking vessel. The monitoring technique involves detecting qualitative or step changes in the temperature-time profile by monitoring qualitative or step changes in the frequency-time profile and/or changes in the first derivative of the frequency-time profile. Independent claims are also included for the following: (a) arrangement for thermal monitoring of an inductively heated cooking vessel (b) and a cooking device with at least one inventive device for thermal monitoring of an inductively heated cooking vessel.
