Abstract:
1. Frying hob arrangement comprising: a planar heating means ( said arrangement comprising first and second magnetic field generators ( each magnetic field generator having two free ends ( the first and second generators together having four poles, wherein, said heating means is arranged in or close to a plane defined by said free ends, said magnetic field generators are controlled by a control means such that they are adapted to generate alternating magnetic fields in said planar heating means, the magnetic fields are converted into heat in said heating means, and said magnetic fields being such that the magnetic field through one of said free ends has an opposed direction as compared to the magnetic fields through the other free ends by a coil of one leg of the first magnetic field generator being fed by a reversed polarity as compared to feeding of the other three coils of the magnetic module, and during each half period three poles have a magnetic field directed in the same direction and the fourth pole having an opposite directed magnetic field and during each next half period the direction of all poles is reversed.
