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.
