Abstract
ABSTRACT OF THE DISCLOSURE
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, a heating source underlying the plate and a cover above said plate which defines a mainly closed space. The 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. Heat given off by the heat source is trans-mitted, substantially completely, through the planar portion of the plate.

The apparatus of this invention will be mainly described with respect to the service conditions thereof for cooking pizza, i.e. to provide those functions which, as was previously described, are difficult and practically not achievable by existing portable types of coo~ing devices.
The apparatus is essentially formed by the combination of a base portion B containing a heat source Sc for the plate P
and a cap or cover C which, superimposed on said plate encloses on said plate a space in which thermal and environmental conditions build up which are similar to those in an oven.
The plate P, made generally of a high thermal conducti-bility metal or metal alloy, comprises a planar portion the oppos-ing faces 34a and 34b of which are smooth and, respectively, ribbed or notched. The opposing surfaces are defined by raised edges 32a and 32b respectively so that the plate forms a pan effective to perimetrally encloses commestible foods superimposed thereon.
At least the surfaces which have to contact the commes-tible foods to be cooked are covered by an anti-adhesive and water and oil repellant layer, in general consisting of a tetra-fluoroethylene resin resis.ant to the apparatus service temperatures.
Under the top portion 40 of the cover C a diaphragm 46 is located which forms an essentially non-conducting interspace.
The diaphragm 46 is mounted in such a way as to be removable, for example by means of unhooking or releasing of a ,r, 4 resilient hook system 52, to allow both the complete cleaning of any portion of the cover and to form a chamber protected from the outer environment but in which the greater rate of thermal exchange (due to the circulating of the air and/or by irrad-ation) assures that, above said plate, a more limited heating builds up (for example of the order of about 70-90C) in such a way as to be effective to allow for said apparatus to be used as food-heater, for slowly cooking foods requiring this type of cooking, for example meat in juices and the like.
A main characteristic of the present invention is that, depending on the orientation of the plate P, the smooth "-surface 34a of said plate is upwardly directed (as in figs. 1,

The apparatus of this invention will be mainly described with respect to the service conditions thereof for cooking pizza, i.e. to provide those functions which, as was previously described, are difficult and practically not achievable by existing portable types of coo~ing devices.
The apparatus is essentially formed by the combination of a base portion B containing a heat source Sc for the plate P
and a cap or cover C which, superimposed on said plate encloses on said plate a space in which thermal and environmental conditions build up which are similar to those in an oven.
The plate P, made generally of a high thermal conducti-bility metal or metal alloy, comprises a planar portion the oppos-ing faces 34a and 34b of which are smooth and, respectively, ribbed or notched. The opposing surfaces are defined by raised edges 32a and 32b respectively so that the plate forms a pan effective to perimetrally encloses commestible foods superimposed thereon.
At least the surfaces which have to contact the commes-tible foods to be cooked are covered by an anti-adhesive and water and oil repellant layer, in general consisting of a tetra-fluoroethylene resin resis.ant to the apparatus service temperatures.
Under the top portion 40 of the cover C a diaphragm 46 is located which forms an essentially non-conducting interspace.
The diaphragm 46 is mounted in such a way as to be removable, for example by means of unhooking or releasing of a ,r, 4 resilient hook system 52, to allow both the complete cleaning of any portion of the cover and to form a chamber protected from the outer environment but in which the greater rate of thermal exchange (due to the circulating of the air and/or by irrad-ation) assures that, above said plate, a more limited heating builds up (for example of the order of about 70-90C) in such a way as to be effective to allow for said apparatus to be used as food-heater, for slowly cooking foods requiring this type of cooking, for example meat in juices and the like.
A main characteristic of the present invention is that, depending on the orientation of the plate P, the smooth "-surface 34a of said plate is upwardly directed (as in figs. 1,
3 and 3AI, or "inverted", i.e. the indented surface thereof is upwardly directed, (as shown by P' in figs. lA, 2, 5 and 5A), so that a drastic modification of the thermal conditions in the space above the plate and the upper surface (24a or 34b) of the plate itself is obtained.
This particularly important effect is mainly due to the shaping, in section in the vertical plane, of the plate outline portions 32a and 32b.
Characteristically, and as particularly shown in the details of figs. 3A and 5A, in the thickness (suitably increased) of said plate perimetral portions, passages 50 are formed, in particular a crown of passages (figs. 2 and 2A) extending all along the height of these perimetral portions. Moreover, the upper and lower edges of the parts 32a and 32b are slanted as shown or in an equivalent manner. At least, the perimetral portions of the electrical resistance 10 (the outline of which, in plan, is fragmentarily reproduced by dashed lines in fig. 4) are located in such a way as to run all along inner lengths but near to the perimetral outline, also in plan, of said outline portions 32a and 32b of the center planar portion of the plate.
The apparatus, assembled as shown in Figs. 3 and 3A, is predisposed to assure the optimal efficiency thereof for an "oven" type of cooking of foods, in particular of pizza. In fig. 3 a set of small arrows indicates the heated air path which tends to rise during the operation of the apparatus.
By locating the plate in the inverted position P' thereof, and as it is represented in fig. 5 (lower portion) and in particular in fig. 5A, the edge or marginal portion 32a of the plate is downwardly directed and it extends as far as the perimetral portion of the diaphragm 12, and preferably it substantially extends as far as under the level of the resistance 10 .
Under these conditions, the super-heated air from the heating source is practically prevented from reaching the openings 50a (which are now the lower openings) of the passages 50, the slanting of the lower edge of the portion 32a, including said openings 50a, contributing to oppose the air movement, so as to obtain the most favourable conditions for carrying out "grill"
types of cooking by the use of an apparatus such as a beefsteaker, in general without using the cover C thereof.
According to a further embodiment of this invention, the device may be provided with suitable means so as it might utilize a gaseous fuel, for example ~but not critically) a gas preservable into gas bottles or cylinders.
According to this embodiment, the heating source Sg (figs. 8 and 9) comprises a tubular frame 66 which is provided with small holes for gas emission. This emission is controlled by a valve 60 which is connected to a handle 62 from which a pipeline 64 branches out to said t~bular frame 66. By means of another pipeline 68 a sensor 70 is controlled, which in its turn controls a safety valve 72 that closes when the flame of the burner fails or, anyhow, when the gas emission must be broken off, so as to avoid for the loss of unburnt gas.
This particularly important effect is mainly due to the shaping, in section in the vertical plane, of the plate outline portions 32a and 32b.
Characteristically, and as particularly shown in the details of figs. 3A and 5A, in the thickness (suitably increased) of said plate perimetral portions, passages 50 are formed, in particular a crown of passages (figs. 2 and 2A) extending all along the height of these perimetral portions. Moreover, the upper and lower edges of the parts 32a and 32b are slanted as shown or in an equivalent manner. At least, the perimetral portions of the electrical resistance 10 (the outline of which, in plan, is fragmentarily reproduced by dashed lines in fig. 4) are located in such a way as to run all along inner lengths but near to the perimetral outline, also in plan, of said outline portions 32a and 32b of the center planar portion of the plate.
The apparatus, assembled as shown in Figs. 3 and 3A, is predisposed to assure the optimal efficiency thereof for an "oven" type of cooking of foods, in particular of pizza. In fig. 3 a set of small arrows indicates the heated air path which tends to rise during the operation of the apparatus.
By locating the plate in the inverted position P' thereof, and as it is represented in fig. 5 (lower portion) and in particular in fig. 5A, the edge or marginal portion 32a of the plate is downwardly directed and it extends as far as the perimetral portion of the diaphragm 12, and preferably it substantially extends as far as under the level of the resistance 10 .
Under these conditions, the super-heated air from the heating source is practically prevented from reaching the openings 50a (which are now the lower openings) of the passages 50, the slanting of the lower edge of the portion 32a, including said openings 50a, contributing to oppose the air movement, so as to obtain the most favourable conditions for carrying out "grill"
types of cooking by the use of an apparatus such as a beefsteaker, in general without using the cover C thereof.
According to a further embodiment of this invention, the device may be provided with suitable means so as it might utilize a gaseous fuel, for example ~but not critically) a gas preservable into gas bottles or cylinders.
According to this embodiment, the heating source Sg (figs. 8 and 9) comprises a tubular frame 66 which is provided with small holes for gas emission. This emission is controlled by a valve 60 which is connected to a handle 62 from which a pipeline 64 branches out to said t~bular frame 66. By means of another pipeline 68 a sensor 70 is controlled, which in its turn controls a safety valve 72 that closes when the flame of the burner fails or, anyhow, when the gas emission must be broken off, so as to avoid for the loss of unburnt gas.
