[0072] According to variant embodiments, the heating elements 22 to be activated can also be selected by an operator as desired.

[0073] According to another variant, the heating elements 22 are configured to activate or be activated depending on the geometric shape of the container/containers 14.

[0074] By way of example, containers 14 can be used with a base having a circular or discoid shape, or polygonal or any other shape suitable for containing food.

[0075] Furthermore, the containers 14 can have substantially vertical walls, or flared walls, depending on the food to be contained and the type of cooking required.

[0076] According to the present invention, the heating elements 22 are the electric type and can for example be tubular electric resistances, or resistive bands, or resistive wires, or can be the inductive type, halogen, infrared, or similar or comparable elements, able to generate heat to convey to the at least one container 14.

The configuration of the heating elements 22 can be the annular type (FIG. 3a), lobed or polygonal, by way of example triangular, quadrangular (FIG. 3b), pentagonal and so on, or also of another type.

[0079] According to variant embodiments described using FIG. 3c, the disposition of the heating elements 22 can be reticular, with the heating elements 22 substantially linear, oriented transversely to each other, for example perpendicularly, so as to activate according to the position assumed by the at least one container 14 on the base 12.

[0080] According to variant embodiments described using FIG. 3d, the disposition of the heating elements 22 can be the matrix type, or point-by-point, with heating elements 22 of the annular type, lobed or polygonal, by way of example triangular, quadrangular, pentagonal and so on, or also of another type, so as to activate according to the position assumed by the at least one container 14 on the base 12.

[0081] In all cases, the disposition of the heating elements 22 can be coplanar, or performed at different depths, depending on the type of heating to be obtained.

[0082] Thanks to these dispositions of the heating elements 22, it is possible to direct heat energy in a circumstantial and point-by-point manner only to the zones of the container 14 to be heated, whether it is only part of the container 14 or all of it.

[0083] According to possible variant embodiments, the activation of the heating elements 22 can also depend on the position assumed by the food inside the container 14.

[0084] The first heating unit 16a comprises sensitive elements 28 configured to detect the position and bulk of the container/containers 14.

[0085] The disposition of the sensitive elements 28 is such as to allow to recognize the size and/or position and/or shape of the at least one container 14 used.

[0086] The apparatus for cooking food 10 can comprise mixing elements, such as a blade 30, of the removable type, selectively associable with the at least one container 14.

[0087] A drive member M2 is associated with the blade 30, suitable to make it selectively rotate.

[0088] According to variant embodiments, the blade 30 can be the type suitable to mix the food contained in the container 14.

[0089] According to other variant embodiments, the blade 30 can be the type suitable to reduce the food contained in the container 14 to pieces, for example to shred and/or mince it.

[0090] The blade 30 can be commensurate with the shape and size of the container 14 used, cooperating with it as a function of the effect to be obtained on the food.

[0094] In addition, the control and command unit 20 can also be associated with the sensitive elements 28. The association allows the control and command unit 20 to recognize which heating elements 22 are activated/can be activated in order to heat the container/containers 14 directly.

[0095] Furthermore, the control and command unit 20 can also collaborate with the second heating unit 16b to selectively switch on/off and/or regulate the heating elements 22.

[0096] According to variant embodiments, the control and command unit 20 can be configured to drive the drive member M1 and activate the ventilation means 32.

[0098] The control and command unit 20 can be configured to set possible cooking variables, such as for example intensity, time and method.

[0099] For example, the control and command unit 20 can be used to set particular heating gradients of the heating elements 22, to time the activation and de-activation of the heating elements 22 and perform a control function if the temperature of the at least one container 14, or its content, exceeds a determinate value.

[0100] Furthermore, the control and command unit 20 can comprise at least a display or screen 26 and a keypad 24.

[0101] The screen 26 can be configured to display and/or set the typical parameters that are useful during cooking and/or heating food, such as for example the temperature in the cooking zone, the weight of the food, cooking times, the power supplied to the heating unit 16a, 16b, it can display cooking modes, such as grill function or browning function, etc.

[0102] To this end, the keypad 24 is configured to set the desired values of these parameters.

[0103] According to variant embodiments, the screen 26 can be configured to display a map showing the spatial location of the heating elements 22 on the base 12.

[0104] The screen 26 can be configured to show which heating elements 22 are active and which are not.

[0105] Furthermore, the screen 26 can be configured to display the location and/or bulk of the at least one container 14 when it is resting on the base 12.

[0106] By means of the control and command unit 20 it is possible to selectively decide which heating elements 22 to activate/de-activate.

[0107] Moreover, the control and command unit 20 can be configured to split the heat energy produced by the heating elements 22.

[0108] The present invention also concerns a method for cooking food which comprises: [0109] positioning at least one container 14 for food on the base 12 and therefore on the first heating unit 16a; [0110] detecting the position and/or the size of the at least one container 14 by means of the sensitive elements 28; [0111] activating some or all of the heating elements 22 at least of the first heating unit 16a which collaborate in the direct heating of the at least one container 14.

[0112] It is clear that modifications and/or additions of parts may be made to the apparatus for cooking food 10 and corresponding cooking method as described heretofore, without departing from the field and scope of the present invention.

[0113] 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 food 10 and corresponding cooking method, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
