DETAILED DESCRIPTION OF SOME EMBODIMENTS

(12) According to the present description, the invention concerns a cooking apparatus for foods 10 for a wide variety of foods, for example potatoes, vegetables, but not only, also rice, cereals in general, pasta, soups, couscous, meat, fish, whether fresh or frozen.

(13) Furthermore, the cooking apparatus for foods 10 is able to perform different kinds of cooking, for example stews, brazing, boiling, roasting, frying, simple heating, sautéing, browning, slow or rapid cooking in general.

(14) With reference to FIGS. 1, 2 and 5, the cooking apparatus for foods 10 can comprise an external container 12.

(15) In a variant embodiment, the external container 12 can be opened at the top by a lid 13.

(16) The presence of the lid 13 is intended to create a protected space with the conditions needed to cook the foods.

(17) Moreover, the lid 13 can be made of the same material as the external container 12, or a material that allows to have substantial transparency and resistance to high temperatures to allow the user to control the cooking.

(18) For example, the lid 13 can be made of polymer material or glass.

(19) The cooking apparatus for foods 10 also comprises an internal container 11 able to contain foods that are in different shapes, for example polyhedral, or rounded, and different consistency (liquid or solid or intermediate, for example a risotto or a soup) and different sizes, for example pieces with a big or small section.

(20) The internal container 11 is delimited by a base wall 14 and at least one lateral wall 15.

(21) In a variant embodiment, the base wall 14 and the lateral wall 15 can be configured to obtain the internal container 11 substantially symmetrical with respect to an axis of symmetry. For example the base wall 14 can be configured circular or quadrangular.

(22) In another variant, the base wall 14 can be configured rectangular or elliptical.

(23) Furthermore, the base wall 14 can be substantially flat, conical, humped, or in general have discontinuities and depressions.

(24) In a variant embodiment, in accordance with the previous variants, the lateral wall 15 can have a continuous surface.

(25) In a variant embodiment, in accordance with the previous variants, the lateral wall 15 can have discontinuities, for example protrusions or depressions. In particular, with a base wall 14 substantially quadrangular or rectangular, the lateral wall 15 can have sharp or not very rounded edges.

(26) In a variant embodiment shown in FIGS. 1, 2 and 5, the lateral wall 15 has at least one stirring element 22 which is a protrusion with respect to the overall surface of the lateral wall 15. The stirring element 22 can be located at any point whatsoever of the lateral wall 15 and acts to stir the food in the internal container 11.

(27) The apparatus for foods 10 comprises a mixing device 16.

(28) The mixing device 16 can be rotatable by means of a drive member 19, around an axis of rotation X, or fixed.

(29) The variant embodiments described hereafter are valid both for fixed mixing blades 17 and also rotating ones.

(30) The mixing device 16 comprises at least one mixing blade 17 and a connection mean 18.

(31) In a variant embodiment, the mixing blade 17 can be connected in fixed mode to the connection mean 18, or can be selectively removable.

(32) The mixing blade 17 is provided with an upending element 20 toward the periphery of the internal container 11 and hence adjacent to the lateral wall 15.

(33) A translation element 21 connects the upending element 20 to the connection mean 18.

(34) The translation element 21 is configured to move at least part of the food in the direction of the upending element 20. In particular, the translation element 21 thrusts the food toward the periphery of the internal container 11.

(35) In a variant embodiment, the translation element 21 can be partly or completely made of polymer material or metal material.

(36) In a variant embodiment shown in FIGS. 2-4, the translation element 21 is configured with a substantially curved profile to promote the movement of the food from the center to the periphery of the internal container 11 during the rotation of the mixing device 16. In this case, the mixing blade 17 is particularly suitable to be used with granular food, that is, food characterized by little cohesion and which does not form intertwined, thick agglomerates (for example rice or other cereals, or pulses).

(37) Hereafter, by the word “center” we mean the symmetrical development point of the internal container 11, or a point as equidistant as possible from each point on the lateral wall 15.

(38) In another variant embodiment, shown in FIGS. 5-7, the translation element 21 is configured to separate the food from the base wall 14. In this case the translation element 21 is configured substantially flat and is particularly indicated for moving cohesive foods, for example potatoes or meat.

(39) With reference to FIGS. 2-7, the upending element 20 has an approach edge 23.

(40) The approach edge 23 is configured to move and lift the foods.

(41) In a variant embodiment, in order to obtain the advantages illustrated hereafter, the direction of rotation of the mixing device 16 must cause the food to be hit first by the approach edge 23.

(42) The upending element 20 also has an exit edge 24.

(43) The exit edge 24 can be made by the continuation of the approach edge 23. Moreover, the exit edge 24 and the approach edge 23 together delimit a lifting plane 26.

(44) In a particular variant embodiment, the exit edge 24 can have a substantially constant height.

(45) In another variant embodiment shown in FIGS. 3, 4, 6 and 7, the exit edge 24 can have a progressively and continuously increasing height from the approach edge 23 to a top 34.

(46) In another variant embodiment, the lifting plane 26 near the top 34 curves toward the center of the internal container 11.

(47) The development in height of the exit edge 24 determines a peripheral edge 35 of the upending element 20.

(48) The peripheral side 35 has a vertical edge 36 with a height equal to the maximum height of the exit edge 24.

(49) In a variant embodiment shown in FIGS. 2-9, in correspondence with the exit edge 24 and on the peripheral side 35, a cleaning element 25 is associated, which extends partly or completely along the exit edge 24.

(50) The cleaning element 25 is advantageously made of flexible material and is configured to adhere to the lateral wall 15 of the internal container 11.

(51) By flexible material we mean for example flexible rubber or similar material suitable to conform to the geometry of the internal container 11. In fact, the cleaning element 25 is suitable to remove the food present on the lateral wall 15 and in particular in correspondence with possible depressions or sharp or not very rounded edges present on the lateral wall 15 and in which food can accumulate.

(52) Moreover, the cleaning element 25 adapts to the presence of possible protrusions on the lateral wall 15, in particular in the presence of the stirring element 22.

(53) In another variant embodiment shown in FIGS. 4, 7 and 9, combinable with any other previous embodiment, the upending element 20 can provide another vertical cleaning element 25a, made in correspondence with the vertical edge 36 of the peripheral side 35. The vertical cleaning element 25a is made of the same material as the cleaning element 25 and has the same functions.

(54) In another variant embodiment, also combinable with each of the others, the upending element 20 and the translation element 21 can be made of a substantially rigid polymer material.

(55) In a variant embodiment, also combinable with each of the others, the mixing blade 17 can be made partly or completely of flexible material. In particular, at least the upending element 20 can be made of flexible material.

(56) In another variant embodiment, also combinable with each of the others, both the upending element 20 and also a part near the periphery of the internal container 11 of the translation element 21 are made of flexible material.

(57) In another variant embodiment, shown in FIG. 8, also combinable with each of the others, a horizontal cleaning element 25b can be associated with the translation element 21, also made of flexible material. The horizontal cleaning element 25b prevents the food from adhering to the base wall 14, or at least allows an adequate removal thereof, and can extend partly or completely along the front profile of the translation element 21 and along the approach edge 23.

(58) In a variant embodiment, not shown, also combinable with each of the others, the horizontal cleaning element 25b can be can be made only in correspondence with the approach edge 23.

(59) In another variant embodiment, shown in FIG. 9, also combinable with each of the others, the horizontal cleaning element 25b is associated with the mixing blade 17 along its whole lower perimeter, to exert an extended action of removing residues and of cleaning a wide surface of the base of the container.

(60) The approach edge 23 and the exit edge 24 define a lifting plane 26.

(61) The lifting plane 26 allows to progressively move the food from the approach edge 23 to the exit edge 24.

(62) In correspondence with the exit edge 24, the food is upended from the periphery toward the center of the internal container 11. Moreover, this is achieved without causing the fragmentation of the food.

(63) The internal container 11 can define a cooking chamber 27 selectively openable/closable by the lid 13.

(64) The food is progressively cooked inside the cooking chamber 27.

(65) The apparatus for cooking food 10 comprises a heating device 28 on the side facing toward the cooking chamber 27.

(66) In a particular variant embodiment, the heating device 28 can comprise at least one heating element 29, 30.

(67) In a particular variant embodiment, the heating device 28 can comprise two heating elements, an upper heating element 29 and a lower heating element 30.

(68) Hereafter, the term “upper” means an element located laterally to the internal container 11, or on the top, that is, in correspondence with the aperture of the internal container 11. In the same way, the term “lower” means an element located below the base wall 14 of the internal container 11.

(69) The heating elements, upper 29 and lower 30, can be tubular electric resistances, or resistive bands or wires, or induction resistances, able to generate heat and to convey it through induction and/or radiation.

(70) The upper heating element 29 can be located in correspondence with the internal side of the lid 13 and advantageously facing toward the food contained inside the internal container 11.

(71) The upper heating element 29 can be connected to a mean to transfer the heat generated 31.

(72) At least one of either the upper heating element 29 or the mean to transfer the heat generated 31 is installed in correspondence with the lid 13.

(73) In a variant embodiment, the upper heating element 29 and the mean to transfer the heat generated 31 can be installed in correspondence with the lateral wall 15.

(74) The mean to transfer the heat generated 31 allows to distribute the heat generated by the upper heating element 29 uniformly inside the cooking chamber 27.

(75) In another variant embodiment, a deflector element 37 cooperates with the upper heating element 29 and the mean to transfer the heat generated 31 to convey the heat generated toward the food.

(76) The lower heating element 30 can be disposed near the base wall 14, that is, immediately under the internal container 11. In this way, the food is also cooked in the part below the internal container 11.

(77) The internal container 11 can be made of metal material, for example an aluminum alloy, or stainless steel or a plastic material resistant to high temperatures.

(78) Furthermore, the internal container 11 can be covered with any other material suitable to contrast any possible adherence of the food to the base wall 14 and the lateral wall 15.

(79) Merely by way of example, the internal container 11 can be coated with PTFE (polytetrafluoroethylene), ceramic material or an enamel.

(80) In a particular variant embodiment the internal container 11 can comprise at least a handle 32 suitable to facilitate the operation to extract the internal container 11 from the external container 12. The handle 32 can be attached to the internal container 11 by screws or rivets, or clamped in snap-in mode.

(81) The internal container 11, depending on the configuration and possibly on the number of handles it has, can contain inside it a quantity of food from 1 kg to 5 kg.

(82) In correspondence with the base wall 14 and coaxial to the axis of rotation X, the internal container 11 can comprise a coupling element 33.

(83) In a variant embodiment shown in FIG. 1, the drive member 19 can be installed under the internal container 11.

(84) In another variant embodiment, the drive member 19 can be installed under the lid 13 and above the internal container 11.

(85) In some variant embodiments, another drive member is provided (not shown in the drawings) which can allow the internal container 11 to rotate.

(86) In a particular variant embodiment, in accordance with the previous variants, the internal container 11 is fixed and the mixing device 16 rotates.

(87) In another variant embodiment, the internal container 11 rotates and the mixing device 16 is fixed. In this particular variant the mixing blade 17 can be connected directly to the lid 13.

(88) In another variant the mixing blade 17 can be attached to the surface of the external container 12.

(89) In another variant the mixing blade 17 can be attached in correspondence with the axis of rotation X to the rotating internal container 11.

(90) The fixed mixing device 16 can be anchored to the external container 12 or the lid 13, and advantageously removable.

(91) In another variant embodiment, in accordance with the previous variants, it can be provided that the mixing device 16 rotates together with the internal container 11 with different speeds of rotation and concordant sense of rotation.

(92) In another variant embodiment, in accordance with the previous variants, it can be provided that the mixing device 16 rotates together with the internal container 11 with different speeds of rotation and discordant sense of rotation.

(93) According to the variant embodiments described above, a method is also defined for mixing food in an internal container 11 by means of a mixing device 16.

(94) Taking as reference a precise moment in time in which the mixing device 16 is rotating, the food is subjected to: a continuous displacement of at least part of the food from the center toward the periphery of the internal container 11; a lifting of at least part of the food by means of the approach edge 23 on the lifting plane 26 and toward the exit edge 24; an at least partial upending of the food at least in correspondence with the top 34 from the periphery toward the center of the internal container 11; a removal of the food present in correspondence with the perimeter edge, or depressions and/or sharp or not very rounded edges, by the cleaning element 25 made of flexible material, associated with or made in a terminal and/or lower part of the upending element 20 and/or of the translation element 21.

(95) It is clear that modifications and/or additions of parts may be made to the apparatus for cooking foods with a mixing device as described heretofore, without departing from the field and scope of the present invention.

(96) 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 apparatus for cooking foods with a mixing device, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
