摘要： The present invention relates to a method for controlling an induction cooking hob, wherein said method comprises an operation mode for estimating the energy efficiency (EE), and wherein said operation mode includes the steps of:
a) estimating (12) the dissipated electric energy (ED) of the induction cooking hob,
b) comparing (14) the dissipated electric energy (ED) with a threshold value (EDthr) for said dissipated electric energy (ED),
c) maintaining (16) the current working parameters of the induction cooking hob, if the dissipated electric energy (ED) is not bigger than the threshold value (EDthr),
d) changing (18) the current working parameters, if the dissipated electric energy (ED) is bigger than the threshold value (EDthr), and
e) repeating the steps a) and b) and then c) or d), respectively, after a predetermined time period.-

摘要： There is described an induction cooking hob (1, 1', 1'') comprising at least one cooking zone (2) for heating a cooking vessel. The cooking zone (2) comprises at least a first induction coil (3) and a second induction coil (4), the first induction coil (3) and the second induction coil (4) being configured to heat the cooking vessel alone or in collaboration with one another. The induction cooking hob (1, 1', 1'') further comprises a power unit (6) operatively connected to and configured to power the first induction coil (3) and the second induction coil (4) and a control interface (5) configured to receive a requested power from a user, the requested power defining and/or being indicative about the power to be delivered to the cooking vessel. The power unit (6) is configured to power the first induction coil (3) and the second induction coil (4) such that the first induction coil (3) delivers, in use, a first power ranging between a first minimum deliverable power and a first maximum deliverable power and the second induction coil (4) delivers, in use, a second power ranging between a second minimum deliverable power and a second maximum deliverable power. The power unit (6) is configured to power the first induction coil (3) and the second induction coil (4) according to a respective powering scheme chosen from a set of powering schemes. The power unit (6) is configured to choose the respective powering scheme in function of the requested power and the first minimum deliverable power, the second minimum deliverable power, the first maximum deliverable power and the second maximum deliverable power.
