Abstract:
1. 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 therewithin, characterized in that the electric heating device ( 4 ) comprises at least one shielded resistor ( 10 ) having the external shield ( 11 ) electrically connected to ground, said apparatus comprises a partition element ( 12 ) made of thermal-insulating and microwave-transparent material, at least a portion of said partition element ( 12 ) being arranged in a position below the shielded resistor ( 10 ) for separating the latter from the microwave generator ( 5 ), the waveguide cavity ( 6 ) comprises a microwave launch aperture ( 13 ) arranged underneath the partition element ( 12 ), through which the microwaves are adapted to exit the cavity ( 6 ) to pass through the partition element ( 12 ), the shielded resistor ( 10 ), the food-support surface ( 3 ) and radiate into the cooking chamber ( 9 ).
