DETAILED DESCRIPTION OF SOME EMBODIMENTS

[0034] Embodiments described here in FIGS. 1-5 refer to an autonomous apparatus 10 for cooking foods, able to perform various cooking modes, such as stewing, brazing, boiling, roasting, frying, simple heating, sauting, browning, slow cooking, or quick cooking in general.

[0035] The autonomous apparatus 10 comprises a support body 12, with which is associated an openable lid 14, an extractable/insertable internal container 16, open at the top and defining a cooking compartment 26 for food, at least one heating device 18 and at least one air flow generator element 20.

[0036] The support body 12 has an external wall 12a and an internal wall 12b, adjacent during use to the container 16.

[0037] Between the external wall 12a and the internal wall 12b there is an interspace 15 which can function as a technical compartment.

[0038] The support body 12 has an upper edge 13 which cooperates at least partly with a lower edge of the lid 14 when the latter is closed to cover the container 16.

[0039] The presence of the lid 14 is functional to create a controlled environment and conditions necessary for cooking the food.

[0040] The lid 14 can be made of the same material as the support body 12, or of a different material.

[0041] Advantageously, at least the lid 14 can be made of at least partly transparent material, to allow the user to view and thus control the cooking.

[0042] For example, the lid 14 can be made of a polymer or glass material.

[0043] The container 16 is defined by a base wall 22, which in this non-restrictive case is substantially circular, and by a lateral wall 24 connected to the base wall 22 and having a peripheral edge 24a.

[0044] The container 16 is configured to allow the association of one or more grips to allow to handle the container 16.

[0045] The base wall 22 can have a surface made with a plurality of configurations, for example conical, or hump-backed, more or less accentuated.

[0046] In a preferred embodiment, to which reference will be made hereafter, the base wall 22 has a substantially flat configuration.

[0047] The container 16 is open at the top to introduce food inside it and to allow the circulation of the flow of air from the heating device 18 to the food.

[0048] The generator element 20 of the flow of air is connected to a return exit 28 having a suction mouth 30 made in correspondence with the internal wall 12a.

[0049] The suction mouth 30 can be, for example, a through hole, or a grid.

[0050] The suction mouth 30 can be disposed at any point whatsoever of the internal wall 12b provided that it allows to determine a closed circuit of the flow of air.

[0051] According to a preferred formulation, the suction mouth 30 is positioned in correspondence with the air flow generator element 20.

[0052] The generator element 20 can be installed at any point whatsoever inside the interspace 15 provided that it allows to recirculate the flow of air.

[0053] The generator element 20 can be, for example, an axial, centrifugal or mixed axial/centrifugal fan, made to rotate by a drive member 44.

[0054] The return exit 28, when the lid 14 is closed on the container 16, cooperates with a plurality of through holes 32 made on at least one portion of the lateral wall 24 of the container 16.

[0055] According to one aspect of the invention, the through holes 32 are present at least partly on the lateral wall 24, in particular on a band near the peripheral edge 24a, so as to allow to accommodate liquid or fluid foods.

[0056] In particular, the band with the through holes 32 extends starting from the peripheral edge 24a for 70%, advantageously 60%, of the height of the lateral wall 24.

[0057] In the embodiment shown in the drawings, the through holes 32 are substantially uniform, and disposed in substantially parallel vertical files, on a substantial part of the height of the lateral wall of the internal container 16.

[0058] This creates a substantially uniform flow of air from the inside to the outside of the container 16, which hits and therefore uniformly heats the food contained inside the container 16.

[0059] In some variants, not shown, through holes 32 can also be present on at least one portion of the base wall 22.

[0060] The through holes 32 can be in vertically aligned rows, as in the solution shown, or in horizontally aligned rows, or else have a random disposition covering a desired part of the lateral wall 24 or base wall 22 of the container 16.

[0061] It is advantageous to provide that the through holes 32, if present in the lateral wall 24, cover a substantial part of the height of the container 16, so that the flow of air is forcedly induced to hit, in a substantially uniform manner, all or at least a large part of the food in the container 16.

[0062] According to a preferred formulation of the present invention, the autonomous apparatus 10 can comprise a sending aperture 34 to send the flow of air, installed on the lid 14.

[0063] According to one embodiment of the present invention, shown by way of example in FIGS. 1-3, the sending aperture 34 can have a substantially hollow toroidal form which cooperates, when the lid 14 is closed on the container 16, with the peripheral edge 24a of the container 16.

[0064] The sending aperture 34 can have a circumferential slit 36 that allows the flow of air circulating in the toroidal cavity to escape from it, to be directed, when the lid 14 is at least partly closed, toward the inside of the container 16.

[0065] According to another embodiment, the sending aperture 34 can have a limited development and in proximity to the heating device 18.

[0066] The autonomous apparatus 10 comprises a recirculation pipe 46 which determines the connection between the generator element 20 and the heating device 18, in practice connecting the return exit 28 to the sending aperture 34.

[0067] According to embodiments described here, in the case where there is the sending aperture 34 with a toroidal or substantially circular development, it develops on a circumference with a smaller diameter than the peripheral edge 24a, in correspondence with the circumferential slit 36, to then increase and abut, with the lid 14 closed, in correspondence with the peripheral edge 24a.

[0068] In this way, the sending aperture 34, abutting against the circumferential edge 24a, creates a hermetic cooking compartment 26, constraining the flow of air to pass through the through holes 32.

[0069] According to one embodiment, shown by way of example in FIG. 5, the autonomous apparatus 10 can comprise an additional auxiliary heating device 47, or alternative to the heating device 18, for example installed in proximity to the base wall 22.

[0070] According to embodiments described here, the container 16 can be rotated around an axis of rotation, preferably in relation to the center of the base wall 22, by means of a drive member 44.

[0071] According to other embodiments described here, the autonomous apparatus 10 can comprise a mixing device 48 which is provided with at least one mixing blade, rotating with respect to the container 16 (FIG. 5).

[0072] It is clear that modifications and/or additions of parts may be made to the autonomous apparatus 10 and corresponding method as described heretofore, without departing from the field and scope of the present invention.

[0073] It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of autonomous apparatus 10 and corresponding method, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
