DETAILED DESCRIPTION OF SOME EMBODIMENTS

[0028] 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, sautéing, browning, slow cooking, or quick cooking in general.

[0029] 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.

[0030] The support body 12 has an external wall 12a and an internal wall 12b, adjacent during use to the container 16. Between the external wall 12a and the internal wall 12b there is an interspace 15 which can function as a technical compartment.

[0031] 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.

[0032] The presence of the lid 14 is functional to create a controlled environment and conditions necessary for cooking the food.

[0033] The lid 14 can be made of the same material as the support body 12, or of a different material.

[0034] 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.

[0035] For example, the lid 14 can be made of a polymer or glass material.

[0036] 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.

[0037] The container 16 is configured to allow the association of one or more grips to allow to handle the container 16.

[0038] The base wall 22 can have a surface made with a plurality of configurations, for example conical, or hump-backed, more or less accentuated.

[0039] In a preferred embodiment, to which reference will be made hereafter, the base wall 22 has a substantially flat configuration.

[0040] 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.

[0041] According to one aspect of the present invention, the generator element 20 is connected to a return exit 28 which, when the lid is in the closed position on the container, cooperates with the peripheral edge 24a of the container 16.

[0042] The return exit 28 is configured to extract the flow of air immediately exiting from the container 16 and to channel it to the heating device 18 by means of an annular pipe 30.

[0043] According to one aspect of the present invention, the annular pipe 30 has ends that are symmetrically connected to the generator element 20.

[0044] In this way, advantageously, the air flow is conveyed and divided symmetrically along the annular pipe 30 to converge toward the generator element 20.

[0045] According to one embodiment, shown by way of example in FIGS. 2 and 3, the annular pipe 30 is installed between the support body 12 and the container 16.

[0046] For example, the annular pipe 30 is installed in the interspace 15.

[0047] Advantageously, the annular pipe 30 encloses a space and channels the flow of air in a univocal manner, determining its closed circuit path.

[0048] In this particular embodiment, the annular pipe 30 has a plurality of slits 32 disposed along the development of the annular pipe 30 and disposed in correspondence with the upper edge 13 of the support body 12.

[0049] The annular pipe 30 develops for the entire circumference of the cooking apparatus 10 and has at least one end connected to the generator element 20.

[0050] The lid 14 advantageously has a hollow internal surface in correspondence with the plurality of slits 32.

[0051] According to one formulation of the present invention, the generator element 20 cooperates with a sending aperture 34 to send the flow of air, provided on the lid 14.

[0052] According to one embodiment of the present invention, which is shown by way of example in FIGS. 1-3 and 5, the sending aperture 34 can have a substantially hollow toroidal shape which cooperates, when the lid 14 is closed on the container 16, with the peripheral edge 24a of the container 16.

[0053] 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, to the container 16.

[0054] 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 of the container 16, to allow to discharge the flow of air from the container 16 to the return exit 28.

[0055] In this way, the sending aperture 34 does not abut against the circumferential edge 24a, thus creating a gap that allows to discharge the flow of air from the container 16 to the sending exit 28.

[0056] According to another embodiment, the sending aperture 34 can have a limited development and in proximity to the heating device 18.

[0057] The autonomous apparatus 10 comprises a recirculation pipe 44 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.

[0058] According to embodiments described here, the recirculating pipe 44 can be configured to determine the continuation of the annular pipe 30 (FIG. 4).

[0059] 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.

[0060] The generator element 20 can be, for example, an axial, centrifugal or mixed axial/centrifugal fan, made to rotate by a drive member 46.

[0061] 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.

[0062] 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 an additional drive member 46.

[0063] 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).

[0064] 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.

[0065] 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.
