DESCRIPTION OF THE EMBODIMENTS

(8) Initially shown and described is a food processor 1, which has a housing that incorporates an electric drive motor, which can be used to rotationally drive an agitator 18, wherein the agitator 18 is allocated to the floor 19 of a preparation vessel 2 that has an upper opening 7.

(9) Also provided in the housing of the food processor 1 is an electrical circuit, and in particular a controller having a microcontroller, which enables a programmed control of a cooking process.

(10) Provided for executing the cooking process are heating means, so as to heat the preparation vessel 2 with the ingredients contained therein. An insertion opening 27 is provided for inserting a plug 17. The plug 17 and insertion opening 27 can be configured according to the USB standard or some other suitable standard. A cable 16 connected with the plug 17 can transmit power to an attachable container 3. However, electrical signals can also be transmitted via the cable 16. In particular, control signals are transmitted via the cable 16.

(11) However, wireless signal transmission is also conceivable in place of a hardwired signal transmission.

(12) Located above the upper opening 7 of the preparation vessel 2 in the exemplary embodiment are several attachable containers 3, 4, 5, wherein the attachable containers 3, 4, 5 are essentially identical in design, and in particular have an identical layout.

(13) The attachable containers 3, 4, 5 essentially differ in that the lowermost attachable container 3 placed directly on the upper opening 7 of the preparation vessel has the cable 16, while the attachable containers 4, 5 that can be placed on the lowermost attachable container 3 have an interface element 15 on their lower side that can be brought into contact with an interface element 14 arranged on the upper side of the attachable container 3, 4, 5. Electrical control signals can be transmitted via the interface elements 14, 15. However, electrical power can also be transmitted via the interface elements 14, 15. A configuration according to the USB standard is provided here as well. The interface elements 14, 15 can be electrical plug elements designed according to the respective standard, wherein contacts establish a conductive connection when an attachable container 4, 5 is placed on an attachable container 3, 4 lying thereunder.

(14) The attachable containers 3, 4, 5 made out of plastic or metal, for example, have a floor 10 that is essentially shown to be flat in the drawings. However, the floor 10 can also be slightly inclined. In particular, it can be funnel-shaped. Located in the middle of the floor 10 is a floor-side opening 12, to which are allocated closure means 13 belonging to the attachable container 3, 4, 5 itself. The attachable container 3, 4, 5 can thus be arranged with a closed floor-side opening 12 and, if required, also be transported or displaced. The closure means 13 of the respective attachable container 3, 4, 5 itself can then be moved from a closed position, in which they close the floor-side opening 12, to an open position, in which the floor-side opening 12 is open. The attachable container 3, 4, 5 itself thus has closure means that are always present in the attachable container 3, 4, 5, and present on the latter regardless of its respective position, even if it is filled outside of the food processor, for example.

(15) Drive elements 25, in particular electromechanical drive elements, can be provided for moving the closure means 13 from the closed position into the open position, and in particular from the open position back into the closed position. The drive elements 25 are preferably also always part of an attachable container 3, 4, 5, i.e., are also displaced and entrained together with the attachable container during transport. The closure means 13 can consist of sliders. In particular, it is provided that the sliders of the closure means 13 be designed like an iris diaphragm.

(16) The drive element 25 shown only schematically and not in detail in the drawings receives control signals from the also just schematically shown controller 26, which is provided in particular in the food processor 1. The control signals are transmitted via the cable 16 or interface elements 14, 15.

(17) The attachable container 3, 4, 5 possesses an essentially cylindrical side wall 9, which has a cavity 11. The cavity can incorporate a temperature-control device, which in particular is a heater and/or cooler, which can be used to temperature-control, in particular cool or heat, the ingredients 23, 24 contained in the attachable container 3, 4, 5.

(18) Each attachable container 3, 4, 5 has a receiving cavity, which is bordered by the side walls and floor 10. The receiving cavity is open at the top. The attachable container 3, 4, 5 there has an upper opening 8.

(19) The upper opening 8 can be closed by an additional attachable container 3, 4, 5 placed thereupon. The upper opening 8 is then closed by the floor 10 of an additional attachable container 4, 5. An uppermost attachable container 5 can here carry a cover that closes its upper opening 8.

(20) Mechanical connecting means 20, 21 are provided, which tie together the attachable containers 3, 4, 5 stacked one on top of the other. In the exemplary embodiment, a connecting element that protrudes over the upper edge 8 of the attachable container 3 is designed as a spring tab with a latching element, which engages into a latching recess in the connecting element 21, wherein the connecting element 21 is arranged on the underside of an attachable container 4, 5.

(21) A display element 22 can be arranged on the outside of the side wall of the attachable container 3, 4, 5, so as to indicate the operating state of the attachable container 3, 4, 5.

(22) A method for preparing meals or operating a food processor 1 with attachable containers 3, 4, 5 of the kind depicted in the drawings can involve the following steps: A first ingredient is initially filled into the preparation vessel 2. An ingredient 23, 24 is likewise filled into at least one attachable container 3, 4, 5. The at least one attachable container 3, 4, 5 is then arranged above the upper opening 7 of the preparation vessel 2. Connecting means can be provided here as well, which connect the lowermost attachable container 3 with the preparation vessel 2 or a cover placed on the preparation vessel 2 and not shown in the drawings, wherein the cover has an opening arranged under the floor-side opening 12 of the lowermost attachable container 3.

(23) In a variant of the method, several attachable containers 3, 4, 5 are arranged one above the other, wherein a different ingredient 23, 24 is stored in each attachable container 3, 4, 5. The lower openings 12 of the attachable containers 3, 4, 5 lie vertically above each other and vertically above the upper opening 7 of the preparation vessel 2, so that the ingredients 23, 24 can fall into the preparation vessel 2 solely through exposure to gravity.

(24) When the cooking process begins, the ingredient contained in the preparation vessel 2 is initially precooked. However, it is also possible to only mechanically process the ingredient there with the agitator 18 in a first step.

(25) After the first cooking step has ended, the opening 12 of the attachable container 3 arranged directly above the preparation vessel 2 is open. To this end, the drive elements 25 receive a control signal from the controller 26. The ingredients 23 arranged in the lowermost attachable container 3 then fall through the open floor-side opening 12 into the preparation vessel 2, where the cooking process is continued.

(26) The floor-side openings 12 of the overlying attachable container 4, 5 remains closed. The floor-side opening 12 in the lowermost attachable container 3 can be closed again, but can also remain open.

(27) At a predetermined second point in time, the floor-side opening 12 of the attachable container 4 is open, and arranged above the attachable container 3. Should the floor-side opening 12 of the attachable container 3 again have been closed, this opening 12 is also opened, so that the ingredients 24 can fall out of the attachable container 4 through the openings 12 of both attachable containers 3, 4 and into the preparation vessel 2.

(28) If additional attachable containers 5 are provided as depicted on FIG. 6, the step is repeated analogously.
