INDUCTION HEATER COMPRISING A CIRCULAR INDUCTOR COIL

摘要

The invention relates to an induction heater comprising a circular inductor coil (16) that has a circular outer contour (22), and a ferrite element arrangement with at least one ferrite element (26) that has a radially external edge (24). In order to improve the functional and structural interaction between adjacent induction heaters in an induction hob, the radially external edge (24) of the ferrite element (26) is curved to a greater extent in at least one point of curvature (28) than the outer contour (22) of the inductor coil (16), thus allowing especially a magnetic field generated by the inductor coil (16) to be specifically modified in a vicinity of said point of curvature (28).
