摘要：
The invention relates to a method for boil detection at a heating zone of an induction hob (1), the method comprising the steps of:
- disabling (S110) a power control mechanism of the induction hob by setting the frequency of the AC-current provided to an induction coil of the induction hob to a fixed value;
- measuring (S120) values of an electrical parameter provided within the induction hob (1);
- interpolating (S130) the measured electrical parameter values by gathering a plurality of values of the electrical parameter within a time window and calculating the average value of said gathered plurality of values thereby obtaining interpolated electrical parameter values.
- calculating (S140) a gradient measure indicative for the differential change of the interpolated electrical parameter values over time;
- determining (S150) the boil point based on the calculated gradient measure.
