Abstract: An induction hob (100) includes a solid plate (105), and a plurality of electrically activatable coil members (1101-1108) arranged underneath the plate. The define corresponding cooking zones (1151-1158) of the induction hob, and a control unit (135) is configured to select power levels for the cooking zones. Upon selection of first (P1) and second (P6) power levels for non-adjacent first (1151) and second (1156) cooking zones, respectively, the control unit is configured to automatically select for each intermediate cooking zone (1152-1155) between the first and second cooking zones a corresponding power level (P2-P5) obtained by interpolation of the first and second power levels with a predefined interpolating function.

Abstract: An apparatus for cooking food products on both sides which has a food-support surface that is transparent to both microwave and infrared radiation, an electric heating device, and a microwave generator. The microwave generator is connected to a waveguide cavity for irradiating the food products. The apparatus also has a food-contact heating surface that, together with the food-support surface, forms a cooking chamber capable of retaining the microwaves inside. The electric heating device has a shielded resistor with the external shield electrically connected to ground. The apparatus has a partition element made of thermal-insulating and microwave-transparent material, a portion of which is below the shielded resistor to separate the resistor from the microwave generator. The waveguide cavity has a microwave launch aperture underneath the partition element.

Abstract: An induction hob (100) is provided. The induction hob comprises a solid plate (105), a plurality of electrically activatable coil members (1101-1108) arranged underneath the plate, said coil members defining corresponding cooking zones (1151-1158) of the induction hob, and a control unit (135) configured to select power levels for the cooking zones. In the solution according to one or more embodiments of the present invention, upon selection of first (P1) and second (P6) power levels for non-adjacent first (1151) and second (1156) cooking zones, respectively, the control unit is configured to automatically select for each intermediate cooking zone (1152-1155) between said first and second cooking zones a corresponding power level (P2-P5) obtained by interpolation of the first and second power levels with a predefined interpolating function.

Abstract: An apparatus for cooking food products on both sides thereof, including a base member (2) comprising a food-support surface (3) transparent to both microwave and infrared radiation, an electric heating device (4) and at least one microwave generator (5), said microwave generator (5) being connected to a waveguide cavity (6) for irradiating the food products, an upper member (7) comprising a food-contact heating surface (8) and adapted to close in onto the base member (2) so as to form a cooking chamber (9) enclosing said surfaces (3,8) and capable to retaining the microwaves there within.

Abstract: Apparatus for cooking food products on both sides thereof, comprising a base member associated to a bottom heating surface, a first electric heating element located between the base member and the bottom heating surface, an upper movable member associated to a top heating surface, a second electric heating element located between said upper member and said top heating surface, and one or more microwave generators housed in the base member; when said upper member is lowered, the top heating surface comes to lie opposite to the bottom heating surface so as to form a cooking cavity therebetween. Said first electric heating element is separated from the bottom heating surface by a hollow space and the microwave generator is placed in such position, with the use of appropriate wave-guide means, as to allow the microwaves issuing therefrom to propagate towards said hollow space and, eventually, towards the bottom surface of said bottom heating surface.
