An apparatus for heating or cooking food is described which comprises a plate forming the hot horizontal surface on which the food to be cooked is placed, at least a heating source underlying the plate, a cover above said plate, which defines a mainly closed space. The metal plate has high thermal conductivity. Preferably, the plate has a raised edge effective to circumscribe and define a space for locating and containing the food. The plate may be inverted and the apparatus may be used as an open grill. In this arrangement heat is transmitted by conduction. The plate is provided with essentially vertically extending passages located, in the perimetral parts of the plate, in section in vertical planes, in such a way that the lower mouth or inlet of said passages fully communicates with the space underlying the plate so that active circulation of superheated air is established between the space underlying the plate and the space above the plate and defined in the inside of said cover. When the plate is inverted, circulation is prevented or at least strongly hindered, thereby the heat irradiated by the source of heat is transmitted, substantially completely, to and respectively through the planar portion of said plate.
A portable cooking apparatus comprising a base, horizontal heating means located in said base, a cooking plate adapted to be heated by said horizontal heating means, said apparatus being used in a first position of said cooking plate as an oven and in a second position of said cooking plate as a grill, cover means adapted to cover said plate so as to leave a gap above said plate, said plate having raised edges, which project vertically to engage said cover means, said cover means having means for the escape of the vapors, said plate being provided perimetrically in said raised edges with conduit means, said plate having a first essentially flat surface and a second ribbed surface, said conduit means having a shape which allows direct circulation of hot air from said heating means to the food placed on the flat surface of the plate when the plate is used in said first position, said plate being invertible and being selectively used in said first position as an oven and in said second position as a grill, the food being placed on said ribbed surface of the plate when the apparatus is used in said second position, heat being transmitted by radiation and conduction through said plate in said first position and the hot air being inhibited from rising through said conduit means in said second position.
