Heating system especially for electric cooking operations

摘要

The heating system for electric cooking operations has at least one cooking ring (12) with an electric heating unit (14), and with a vessel, the contents of which are to be heated. The heating unit has facilities (15) for transmitting inductive fields. The vessel has at least one insert element, which at least partly consists of at least one material with ferromagnetic characteristics. This material has a Curie temperature, which lies in the region of at least one limit temperature, which is provided for the vessel (22) and/or its contents. Means (16) are provided for the alternation, especially for switching off, the heating power of the heating unit (14). The insert element (23) for determined characteristics consists of several ferromagnetic material with different Curie temperatures.
