  • Patent number: 10536995
    Abstract: An induction heating arrangement (1000) including four coils of a smaller diameter (1100, . . . , 1400) and a coil having a larger diameter (1500) is provided. The coils are arranged on a first plane (2100) and on a second plane (2200). In order to adapt a cooking area (1600) to the size of a pot, either the larger coil (1500) or one or more of the smaller coils (1100, 1400) are operated. A power supply circuitry (2400) is shared between the coils of the two planes. A selector (2300) disconnects a respective coil of the plane of coils that is not operated in order to avoid coupling, interference and loss of energy. Guiding elements of the magnetic flux (1110, 1115, 1540) confine the magnetic field in the area of the pot. A method of operating the induction heating arrangement is also provided.

  • Patent number: 9615692
    Abstract: A grill and/or frying plate for use on an induction cooking hob, including at least one grill section and at least one section different from the grill section, in particular a frame section or a warming section. When the grill and/or frying plate is mounted to the cooking hob, the at least one grill section is at least partially arranged directly above at least one heating element of the cooking hob and that the at least one section different from the grill section is at least partially arranged in a position where no heating element is arranged below.
