Abstract

A method for checking an ideal position of a cooking pot above an induction coil of an induction cooking hob is provided. The method includes the steps of: detecting a first parameter related to the power of the electromagnetic field and/or to the position of the cooking pot above the induction coil, detecting a second parameter related to the power of the electromagnetic field and/or to the position of the cooking pot above the induction coil, comparing the detected first and second parameters with a stored relationship between the first and second parameters and the position of the cooking pot above the induction coil, determining a deviation of the position of the cooking pot from the ideal position above the induction coil, and outputting at least one signal corresponding with the deviation of the position of the cooking pot from the ideal position, if the deviation exceeds a minimum value.
