Description

The invention relates to a food processor according to the preamble of claim 1. The invention also relates to a chopper add-on set and a method for chopping items to be cut.

Multifunction food processors are known, for example, under the Thermomix® brand in the prior art. The known food processors have a control and drive unit as well as a mixing bowl with a shaft arranged on the floor, from which the cutting blade extends. The mixing bowl is inserted into the control and drive unit, whereby a coupling between a drive socket, which is arranged on the control and drive unit, and the shaft in the mixing bowl bottom takes place, so that right and left rotations of the drive socket on the shaft in the mixing bowl bottom and transferred to the cutting blades. There is also a lid for the mixing bowl and locking claws which, after the control and drive unit has been switched on, securely lock the mixing bowl lid on the mixing bowl and protect it from accidental, unintentional intervention by the operator in the mixing bowl during operation.

For example, from the DE 2021 101 580 a tea strainer that can be used in the mixing bowl. This makes it possible to prepare hot tea using the Thermomix®. The heating function of the control and drive unit is used and switched on for this purpose. A disadvantage of the known supplementary sets and kitchen appliances is their still limited usability.

It is therefore the object of the present invention to open up a food processor for further applications.

In a further aspect, it is an object to provide a chopper add-on set that can be built into a food processor.

In a third aspect, the object of the invention is to provide a method for chopping items to be cut with a chopper add-on set and/or with one of the kitchen appliances mentioned above.

The object is achieved in its first aspect by a food processor with the features of claim 1.

The food processor according to the invention comprises a control and drive unit, a mixing bowl with a shaft end that protrudes into the mixing bowl and can be driven by the control and drive unit. A shaft preferably has the shaft end protruding into the mixing bowl and a shaft end protruding from the mixing bowl. The end of the shaft protruding from the mixing bowl is coupled to a drive socket of the control and drive unit in operation and transmits right and left rotary movements of the drive socket via the shaft to cutting edges preferably provided on the end of the shaft protruding into the mixing bowl.

According to the invention, the food processor includes a chopper extension set with a rod that can be plugged onto the end of the shaft protruding into the mixing bowl, and with a chopper bowl that can be placed on the mixing bowl. The chopper pot does not have to be in direct contact with the mixing bowl itself, but can also be placed on a mixing bowl lid. The rod is a freely movable separate component. It is not required for the food processor to function without the chopper function.

According to the invention, a cutting disk is arranged in the chopper bowl so that it can rotate with respect to the chopper bowl. The cutting disc is arranged on the rod. On the mixing bowl side of the cutting disc there is an ejection disc which is arranged such that it can rotate relative to the chopper bowl and is also arranged on the rod. In addition to the ejection disk, an ejection opening, preferably for chopped material to be cut, is arranged on an outer wall of the chopper bowl. A filling opening for the material to be cut is also arranged on the chopper bowl.

The food processor according to the invention advantageously has a chopper function, which has not previously existed in the prior art for food processors, in particular the “Thermomix” food processor.

The chopper supplementary set comprises a rod with an ejector disc, which is preferably arranged in a rotationally fixed manner relative to the rod, and a cutting disc, which is preferably arranged in a rotationally fixed manner in relation to the rod. The constellation of rod and cutting disc as well as ejector disc is rotatably arranged in an interior of a chopper bowl. On an outer wall, the chopper bowl has the filling opening for filling in the material to be cut and the ejection opening for ejecting the chopped material to be cut. The material to be cut is preferably fruit and vegetables. Of course, other foods can also be fed to the shredder.

Preferably, the cutting disc and the ejector disc are each arranged in a rotationally fixed manner on a rod section of the rod, and the rod end on the side of the mixing bowl is arranged opposite the rod section on the rod is arranged horizontally, is plugged into the shaft end in a rotationally fixed manner. The end of the shaft protruding into the mixing bowl advantageously has cutting edges which protrude from the end of the shaft in a star shape, for example. Claws arranged at the rod end can be inserted between the cutting edges. The claws can be designed in an extension along the circumference so that they fit exactly between two adjacent cutting edges and thus form a non-rotatable connection during operation of the food processor between the shaft end protruding into the mixing bowl and the rod end having the claws.

Of course, other forms of connection between the end of the rod and the end of the shaft are also conceivable.

For optimal functioning of the chopper, the ejection opening is advantageously arranged between the cutting disc and the ejection disc, preferably on the side of the chopper bowl, and the filling opening is preferably arranged on an outer wall, preferably on the upper side of the chopper bowl, away from the ejection disc. The chopper pot itself conveniently has a pot or bucket-like shape.

The design makes it possible to first press the fruit and vegetables through the filling opening onto the cutting disc, which cuts the material to be cut. From there, the chopped material falls onto the ejection disc and is thrown out of the ejection opening by rotating the ejection disc. For this purpose, an upper edge of the ejection opening is advantageously located somewhat below a radially outer edge of the ejection disk.

In a favorable embodiment of the invention, the cutting disk and the ejection disk are plugged onto the rod section in a plug-in mechanism. Conveniently, the rod section has a receiving means that has a peripheral outer profile that forms a form fit with a peripheral corresponding inner profile of the cutting disc, the corresponding inner profile being arranged in a central opening of the cutting disc. The cutting disk is preferably circular in shape with a centrally located circular opening having the corresponding internal profile along its inner wall.

Cutting edges are provided on the top and/or bottom of the cutting disc. The cutting disc can also be rotated by 180°.

Conveniently, the rod section has a further receiving means, which is arranged next to, preferably directly next to, the receiving means on the side of the mixing pot base, and the further receiving means has a peripheral further outer profile, which forms a positive connection with a further corresponding inner profile of the ejector disc, and the further corresponding inner profile is arranged in a further central opening of the ejection disc. This embodiment of the invention makes use of the idea of first attaching the ejector disk to the rod section. The further corresponding inner profile is first completely guided over the peripheral outer profile and fed to the further outer profile onto which it is placed, so that the ejection disc with its further corresponding inner profile is placed non-rotatably on the corresponding outer profile of the further receiving means. A stop ring is preferably provided on the mixing pot bottom end of the further receiving means, which prevents the ejector disc from slipping off towards the mixing pot bottom.

The cutting disc is then attached to the rod section. To do this, the inner profile of the cutting disc is guided onto the outer profile of the bar section, where both form a non-rotatable connection with one another.

Almost any shape is conceivable for forming the profiles, which at least allows the ejection disk and the cutting disk to be shifted back and forth in the longitudinal direction in the associated receiving means.

In a preferred embodiment of the food processor according to the invention, the cutting disc has an underside and an upper side, the cutting disc being attachable to the rod section with either the underside pointing towards the filling opening or with an upper side pointing towards the filling opening. In the first case, the cutting disk is placed in a first position on the rod section, in the second case it is placed in a second position on the rod section. Preferably, both the top and bottom have clockwise and counterclockwise cutting tools. The cutting tools can be cutters, i.e. simple blades, arranged radially in a clockwise or counter-clockwise direction, or rasps, arranged in a clockwise or counter-clockwise direction.

Two types of cutting tools are preferably provided at the top and two other types of cutting tools at the bottom provide tools. Orientated clockwise and counterclockwise, respectively. The cutting tools can be designed as one or more rasps or one or more blades. Any combination of rasps or blades can be provided on the top or bottom, for example two blades of different height and/or length on the top and/or bottom can point in the same direction and form a cutting tool or point in opposite directions and two different ones train cutting tools. The same applies to the rasps. Blades and rasps can also be provided on the upper and/or lower side and point in the same or opposite directions there.

Other types of cutting tools can also be provided.

According to the invention, various configurations of a chopper pot rim are provided with which the chopper can be arranged on a mixing bowl lid that is placed directly on the mixing bowl or with which the chopper pot can be placed directly on a mixing bowl rim.

A mixing bowl lid is preferably placed on the mixing bowl with an edge surrounding a mixing bowl rim, and the mixing bowl lid has a lid strip surrounding a lid hole arranged centrally in the mixing bowl lid, and the chopper bowl has a chopper bowl rim with which the chopper bowl is held on the circumferential lid strip. The mixing bowl lid is preferably placed directly on the mixing bowl rim and touches it, while the chopper pot rim does not directly touch the mixing bowl rim, but only touches the mixing bowl lid and is held there on the lid strip surrounding the lid hole. The cover strip surrounds a preferably circular cover hole, preferably concentrically. The mixing bowl lid is also preferably circular in plan view. Conveniently, the chopper pot rim has an inside diameter that corresponds to an outside diameter of the peripheral cover strip. This makes it possible to attach or clamp the chopper bowl onto the cover strip. Favorably, the cover strip tapers slightly conically towards the outside of the cover with a slightly decreasing outside diameter, so that the chopper bowl rim can be clamped onto the cover strip with a preferably constant inside diameter.

Based on this, in a first embodiment, the chopper pot rim has an externally arranged hook that grips under a mixing pot handle in the operating state, and a retaining strip opposite the hook that grips under a loop handle of the control and drive unit in the operating state. Hooks and retaining strips are arranged outside at the lowest end of the chopper bowl rim. Preferably, the chopper bowl is locked on the lid by a rotary movement, and the retaining strip advantageously tapers radially in the direction of rotation and, in the operating state, abuts against the direction of rotation on a lateral inner wall of the bow handle when locking, while the hook in the direction of rotation abuts the mixing bowl handle on the side. As a result, the chopper bowl is locked on the mixing bowl lid in the direction of rotation and against the direction of rotation in the operating state. One direction is prevented by the retaining strip, the other direction is prevented by the hook. In addition, the hook grips the mixing bowl handle and the retaining strip grips the loop handle so that it is no longer possible to lift off the chopper bowl once it has been locked.

In a second embodiment, the rim of the chopper bowl has a horizontal and a vertical stripe on the outside in the circumferential direction, and recesses are provided in the horizontal stripe, preferably closed recesses, into which the claws of the control and drive unit engage in the operating state, the recesses being on the side of the mixing bowl are closed by the vertical strip, preferably fully closed, and the claws straddle the vertical strip in the portion of the recesses in the operative condition. In the second embodiment, too, the edge of the chopper bowl is placed on the mixing bowl lid that is placed on the mixing bowl. It does not replace the mixing bowl lid.

In a third embodiment of the chopper bowl according to the invention, the chopper bowl rim has a horizontal strip, and open recesses are provided in the horizontal strip. The open recesses can thus split the horizontal strip into individual strip sections. The claws of the control and drive unit engage in the cutouts in the operating state, and a length of the cutouts in the circumferential direction corresponds to the length of the claws in the circumferential direction. The length of the claws and the length of the recesses are dimensioned in such a way that the claws engage exactly in the recesses when locking, so that when there is a movement in the direction of rotation or against the direction of rotation, the recesses immediately hit the locked claws with their inner edges and a rotary movement in both directions is prevented by the claws. In addition, a hook is arranged on the outside of the chopper pot, which engages under a mixing pot handle in the operating state, and a flag is arranged opposite the hook, which one Grips under the handle of the control and drive unit when in operation. The hook and flag prevent accidental and unwanted lifting of the chopper bowl from the mixing bowl lid when in use. The hook is advantageously designed in the same way as the first embodiment, while the flag differs in shape from the retaining strip and can be designed significantly narrower and, for example, simply rectangular in a plan view and does not have to hit the side of the bow handle in the operating state.

In a fourth embodiment, the rim of the chopper pot is placed directly on the rim of the mixing bowl and encompasses the rim of the mixing bowl, and claws of the control and drive unit engage over the rim of the chopper pot in an operating position and press it onto the rim of the mixing bowl.

The object is achieved in its second aspect by a chopper supplementary set with the features of claim 14.

The shredder extension set is suitable for installation in one of the kitchen machines mentioned above. Conversely, each of the above food processors conveniently includes one of the following chopper supplement sets.

The chopper extension set includes a chopper bowl and a rod with a rod end that can be plugged onto a shaft end. The bar comprises a bar section, which is arranged inside the chopper bowl, and a cutting disc rotatably arranged in the chopper bowl, which is arranged non-rotatably on the bar section, and an ejector disc arranged rotatably in the chopper bowl, which is arranged non-rotatably on the rod section, and an adjacent to the Ejection disk arranged on an outer wall of the chopper bowl and a filling opening arranged on the chopper bowl. The additional set for choppers according to the invention is kept simple in structure, and all components can preferably be predominantly plastic injection-molded components. The cutting edges of the cutting disc are preferably made of steel. A steel pin is preferably also arranged at a tip of the rod, which is otherwise preferably made of plastic

The ejection opening is preferably arranged between the cutting disc and the ejection disc, and the filling opening is arranged on the ejection disc side of the cutting disc in an outer wall of the chopper bowl. With regard to the arrangement, reference is made to the description of the food processor, and what has been said above also applies to the chopper supplementary set as disclosed.

The rod section preferably has a receiving means which has a peripheral outer profile which forms a form fit with a peripheral corresponding inner profile of the cutting disc, and the corresponding inner profile is arranged in a central opening of the cutting disc. The rod section has a further receiving means, which is arranged next to the receiving means, and the further receiving means has a peripheral further outer profile, which forms a form fit with a further corresponding inner profile of the ejector disc, the further corresponding inner profile in a further central opening of the ejector disc is arranged and the further corresponding inner profile can be pushed completely over the outer profile. The ejector disk and the cutting disk can be pushed onto the rod section and can also be removed from it again.

The additional chopper set according to the invention preferably has a cutting disc which has a bottom and a top and which can be attached to the rod section with either the bottom pointing towards the filling opening or the top pointing towards the filling opening and both the top and the bottom pointing in the direction of the Has clockwise and counterclockwise cutting tools. The cutting disc according to the invention therefore makes it possible to provide the clippings in four different types of cuts, depending on whether the cutting disc is attached to the rod section in the first or in the second position and depending on whether the control and drive unit is clockwise or is rotated counterclockwise. Otherwise, what was said for the food processor also applies to the shredder extension set.

The object is achieved in its third aspect by a method having the features of claim 18.

The method is suitable for implementation with one of the kitchen appliances mentioned above, which preferably have one of the additional chopper sets. Conversely, each of the kitchen machines mentioned above is suitable for carrying out one of the methods mentioned below.

According to the invention, a rod with a rod end on the side of the mixing pot base is placed on a drivable shaft protruding into a mixing pot. A mixing bowl lid with a center hole in the lid is placed on the mixing bowl and the stick is inserted through the center hole in the lid. Preferably, an ejection disc is placed on the rod beforehand, and preferably a cutting disc is placed thereafter. The chopper pot is about the The cutting disc and the ejection disc are put over and the chopper bowl is locked to the food processor.

A mixing bowl lid is preferably placed on the mixing bowl with an edge that overlaps a mixing bowl edge, the mixing bowl lid having a lid strip surrounding a central lid hole, and the chopper bowl having a chopper bowl edge, and the chopper bowl being placed with the chopper bowl edge on the circumferential cover strip.

The invention makes use of the idea of using a lid strip that is present on the mixing bowl lid to put on the chopper bowl. Conveniently, the chopper bowl rim has an inner diameter that corresponds to an outer diameter of the encircling cover strip, and the chopper bowl rim is clamped in or around the encircling cover strip. As described above, the cover strip can taper somewhat conically towards the top on the outside, so that the edge of the chopper bowl can be clamped onto the cover strip with a constant inner diameter in the longitudinal direction.

In a first embodiment of the method according to the invention, a hook is arranged on the outside on the edge of the chopper bowl in the direction of rotation and opposite on the outside on the edge there is a retaining strip that becomes wider counter to a direction of rotation when locking. The chopper bowl is placed on the mixing bowl lid so that the hook is preferably positioned completely adjacent to the mixing bowl handle, and the chopper bowl is then rotated in the direction of rotation until the hook hits the side of the mixing bowl handle and engages under the mixing bowl handle. During the rotation of the chopper bowl, the retaining strip is rotated under the bow-shaped handle of the control and drive unit, and the mixing bowl is automatically pushed forwards, preferably because the retaining strip has a conical shape that widens counter to the direction of rotation, and when the chopper bowl reaches its end position the retaining strip snaps under the loop handle by tipping the mixing bowl backwards into its operating position and locking the chopper bowl onto the lid. The method is particularly suitable for implementation with the food processor of the first embodiment.

In a second embodiment of the method according to the invention, the chopper pot edge has a horizontal and a vertical strip in the direction of rotation, and recesses are provided in the horizontal strip, and the recesses are closed on the side of the mixing bowl by the vertical strip. When locking the chopper bowl, the claws of the control and drive unit are screwed into the recesses and the claws overlap the vertical strip in the section of the recesses in the operating state. This method is particularly suitable for implementation with a food processor according to the second embodiment.

To carry out a third method according to the invention, a horizontal strip is provided on the outside of the chopper bowl rim, and open recesses are provided in the horizontal strip, a length of the recesses in the circumferential direction corresponding to the length of the claws in the circumferential direction. A hook is arranged in the direction of rotation on the outside of the chopper pot rim, and a flag is arranged opposite the hook. The chopper bowl is placed onto the mixing bowl lid so that the hook is again preferably positioned fully adjacent to the mixing bowl handle, and the chopper bowl is then rotated until the hook strikes the side of the mixing bowl handle and engages under the mixing bowl handle. The flag then grips the bow handle. Now the claws can be closed, i. H. rotated and engage the notches and lock the chopper bowl onto the mixing bowl lid as in the method embodiments above.

This method is particularly suitable for implementation with the third embodiment of the food processor according to the invention.

In order to carry out a fourth method according to the invention, the chopper pot has a chopper pot rim which is placed directly on a mixing pot rim and encloses the mixing pot rim. Claws of the control and drive unit overlap the rim of the chopper pot in an operating position and press it onto the rim of the mixing bowl. In this embodiment of the method according to the invention, the conventional mixing bowl lid can be dispensed with and the chopper bowl is placed directly on the mixing bowl rim. The claws can easily lock the chopper bowl on the edge of the mixing bowl.

In a preferred development of the method according to the invention, a type of cut for the material to be cut is first determined, then a position of the cutting disk and a direction of rotation of the control and drive unit are determined from the type of cut, and then the cutting disk is placed on the rod section in the determined position, and the cutting disc is rotated by the control and drive unit in the determined direction of rotation. The cutting disc according to the invention preferably makes it possible to provide four types of cuts for the material to be cut. However, it is also conceivable that the cutting disc is designed to form three or two types of cuts.

The position of the cutting discs is preferably determined first and then the direction of rotation. This can also be done vice versa.

1 shows a multifunctional food processor 1 with a control and drive unit 2 on which rotatable claws 5 are provided for locking a mixing bowl lid 3, and with a recess 4 into which a mixing bowl 6 with the mixing bowl lid 3 placed on it can be inserted. 1 shows the food processor 1 in an open position of the claws 5. On the mixing bowl lid 3 a chopper supplement set according to the invention is placed in a first embodiment.

The food processor 1 conventionally has the mixing bowl lid 3 . A chopper pot 7 according to the invention with an internal structure described later and with a turning/locking mechanism is placed on the mixing pot lid 3 . The turning/locking mechanism enables the chopper bowl 7 to be locked in place on the mixing bowl lid 3 so that it cannot rotate or tilt.

The mixing bowl lid 3 has a central lid hole 8 and a lid strip 9 that runs concentrically around the lid hole 8 and protrudes vertically upwards from an outer surface of the mixing bowl lid 3 . The cover hole 8 is in the 6 and 7 to recognize.

The cover strip 9 has a constant height and a thickness that increases conically towards the mixing bowl cover 3 along its entire circumference. The chopper pot 7 , which has a chopper pot rim 11 running around the mixing pot side, is placed on the cover strip 9 . The chopper bowl rim 11 has a preferably circumferentially constant inner diameter, which corresponds to a preferably also circumferentially constant outer diameter of the cover strip 9, as well as a stop ring 12 arranged inside the chopper bowl 7, so that the chopper bowl 7 with the chopper bowl rim 11 can be placed and clamped on the outside around the cover strip 9 is. In the fitted state, the cover strip 9 abuts against the stop ring 12 in the interior of the chopper pot 7. The chopper pot edge 11 also overlaps the cover strip 9 on its radial inner side. It forms a kind of U-shaped recess into which an upper edge of the cover strip 9 is plugged in. The overlap on the inside prevents the juice produced during chopping from running from the inside to the outside between the edge of the chopper bowl 11 and the cover strip 9 .

The chopper bowl 7 is rotatably mounted on the mixing bowl lid 3 under the action of force. By turning the shredder bowl 7 clockwise on the mixing bowl lid 3, a hook 13 grips a mixing bowl handle 14, and a rear retaining strip 16, which tapers conically in a clockwise direction, increasingly grips a rear loop handle 17 of the control and drive unit 2 with a clockwise rotary movement until the tapered retaining strip 16 snaps under the bow handle 17. The claws 5 can be closed by switching on the control and drive unit 2 after the locking of the tapered retaining strip 16 . The chopper bowl 7 has a firm, non-rotatable hold on the mixing bowl lid.

The chopper pot 7 according to 2 laterally has an ejection opening 18 with an ejection nozzle 19 and a filling opening 21 with a filler neck 22. The filler neck 22 has two filling channels 22a, 22b, through which clippings can be filled into the chopper bowl. 3 shows a stamp 23 with two stamp rods 23a, 23b, which can be inserted into the two channels 22a, 22b of the filler neck 22, so that they press the clippings filled into the filler neck 22 into the interior of the chopper bowl 7.

In 4 the chopper extension set is shown with its internal structure. The chopper pot 7 has a rod 24 in addition to the chopper pot 7 and the plunger 23 . The rod 24 is in 5 shown. In the operating state, the rod 24 is guided through the cover hole 8 and is placed with one end on the side of the mixing bowl on a shaft end 26 protruding into the mixing bowl 6 . The rod 4 has claws 27 at its end on the side of the mixing bowl, which grip around the cutters 28 arranged on the shaft end 26 (not shown) and thus create a plug-on connection between the rod 24 and the shaft end 26 that is non-rotatable when plugged in. The rod 24 tapers conically towards the end on the cover side and has a rod section 29 on the end on the cover side, which has a receiving means 31 and a further receiving means 32 at its disposal. This in 5 The lower further receiving means 32 is intended for receiving an ejection disk 33 which is non-rotatable relative to the rod 24 and slopes down radially outwards, while the receiving means 31 is intended for receiving a cutting disk 34 in a non-rotatable manner.

The shredder extension set is in the 4 , 6 , 7 shown in assembled condition. The cutting disc 34 has cutting edges and/or rasps. The material to be cut, which is fed into the chopper bowl 7 through the filler neck 22, is chopped by the cutting disc 34, and it falls through the force of gravity onto the ejection disc 33, which rotates during operation, and is discharged by the ejection nozzle arranged laterally next to the ejection disc as a result of the rotation of the ejection disc 33 19 and falls from there into a bowl 35 outside the food processor 1.

In the 7a and 7b an embodiment of the cutting disc 34 according to the invention is shown. The cutting disk 34 is circular and has the inner profile in the center of a short tube 71, which is designed, for example, in the form of a six-tooth profile. In the 7a a top 72 of the cutting disc 34 is shown in which 7b an underside 73 of the cutting disc 34 is shown. The inner profile of the cutting disc 34 can be pushed onto the receiving means 31 of the rod section 29 . In this case, after being attached, the upper side 72 in a first position and the lower side 73 in a second position can point upwards towards the filling opening 21 . The cutting disc 34 can therefore be placed on the receiving means 31 in two different positions, which are rotated 180° relative to one another about a transverse axis.

In the 7a The upper side 72 shown has various cutting tools, it has a first cutting edge 74 which becomes effective when the cutting disk 34 rotates clockwise in the first position. The upper side 72 additionally has fine rasps 76 which become effective when the cutting disk 34 rotates counterclockwise in the first position. The fine rasps 76 point counterclockwise with their blades. The first cutting edge 74 points in a clockwise direction. The fine rasps 76 consist of a series of radially juxtaposed, closed-back, semi-tubular elevations that open counterclockwise. During use, they form fine, elongated material to be cut, while the first cutting edge 74 separates thin slices from the material to be cut.

The cutting disc 34 is preferably formed primarily of steel. Conveniently, the tube 71 is a plastic injection molded part that is injection molded onto the cutting disc 34, which is otherwise made entirely of steel.

In the 7b The underside 73 shown also has various cutting tools. It has a second cutting edge 77 which stands out a little further from the bottom 73 than the first cutting edge 74 stands out from the top 72 . The second cutting edge 77 points counterclockwise. When the cutting disk 34 rotates counterclockwise and is in the second position is built, the second cutting edge 77 cuts thicker slices than the first cutting edge 74 from the material to be cut. Furthermore, coarse rasps 78 are provided on the underside 73 . In principle, the coarse rasps 78 are constructed in a similar way to the fine rasps 76, except that they have a larger internal diameter, so that thicker, elongate material to be cut can be peeled off the material to be cut. The coarse rasps 78 point in a clockwise direction. The control drive unit 2 allows rotation of the cutting disc 34 in both positions, both clockwise and counterclockwise of the rod 24, so that the cutting disc 34 in both the first position according to 7a in the clockwise and counterclockwise direction and also in the second position according to 7b can be rotated in the clockwise and counter-clockwise directions, so that four cutting patterns are possible by fitting and rotating the cutting disc 34 in conjunction.

The receiving means 31 has according to 5 a circumferential outer profile. The peripheral outer profile forms a form fit with a corresponding inner profile of the cutting disc 34, which is arranged in a central opening of the cutting disc 34. The further receiving means 32 has a circumferential further outer profile. The further outer profile interacts with a further corresponding inner profile which is arranged at a central opening of the ejector disc 33 . The other outer profile and the other corresponding inner profile also together form a form fit.

So that the ejector disc 33 can be plugged onto the rod section 29 first and then the cutting disc 34 above the ejector disc 33 according to FIG 4 can be plugged onto the rod 24, the further inner profile is at least as large in each further radius as each radius of the outer profile, so that on the one hand the further inner profile can be guided over the outer profile and additionally the inner profile cannot be guided over the further outer profile. The rod 24 has a stop ring 38 at the end of the rod section 29 on the mixing bowl side, which holds the ejector disc 33 on the further receiving means 32 and does not allow the ejector disc 33 to slip through to the bottom of the mixing bowl 6 .

A distance in a longitudinal direction L between ejection disk 33 and cutting disk 34 corresponds to a height of the ejection opening 18. The ejection disk 33 is arranged at the lower edge of the ejection opening 18, while the cutting disk 34 is arranged above the upper edge of the ejection opening 18. The rod 24 can be driven by the control and drive unit 2 via the shaft end 26 protruding into the mixing bowl 6 in right and left rotation and thus drives both the ejector disc 33 and the cutting disc 34 and thus enables the chopping function.

6 shows the food processor with the chopper supplement set of the first embodiment in a sectional view along a line VI-VI in 1 . The mixing bowl 6 has on a floor the shaft end 26 which protrudes into the mixing bowl 6 and on which the cutting edges 28 are arranged, over which the end of the rod 24 on the side of the mixing bowl is inserted. The mixing bowl 6 comprises a shaft with a shaft end 36 protruding from the mixing bowl 6 and the shaft end 26 protruding into the mixing bowl 6 , the shaft end 36 protruding from the mixing bowl 6 being plugged onto a drive socket 37 . The drive socket 37 is part of the control and drive unit 2 and can be rotated to the right or left and drives the shaft via a plug connection. The mixing bowl 6 is placed in the recess 4 in a fixed position on the drive socket 37 .

The mixing bowl 6 is covered with the mixing bowl lid 3 in a conventional manner. The mixing bowl lid 3 has a lid edge which is held by the claws 5 on an edge of the mixing bowl 6 in the operating state. To open the mixing bowl lid 3, the claws 5, as in 6 shown, rotated and release mixing bowl lid 3. The mixing bowl lid 3 is not part of the chopper extension set, in particular not part of the chopper bowl 7, rather the chopper bowl 7 according to 5 and 6 on the mixing bowl lid 3, namely on the lid strip 9. For this purpose, the chopper bowl 7 has the chopper bowl rim 11 on the cover side, which has an inner diameter that corresponds to an outer diameter of the cover strip 9, the outer diameter of the cover strip 9 decreasing slightly from the bottom upwards along the longitudinal direction L because the cover strip 9 is slightly conical. while the inner diameter of the cover strip remains constant over the entire length in the longitudinal direction L, so that the cover pot 7 can be pressed onto the cover strip 9 and forms a clamping connection with the cover strip 9 .

The chopper bowl 7 does not come into contact with the claws 5 during operation, rather the chopper bowl 7 is locked to the food processor 1 by means of the hook 13 on the mixing bowl 6 and the rear conical retaining strip 16 . To do this, the hook 13 grips the mixing bowl handle 14, and the conical retaining strip 16 grips the loop handle 17 of the food processor 1.

The locking mechanism is in the 8th , 9 and 10 shown. In 8th the operating position with closed claws 5 is shown puts, in 9 the locked position of the chopper bowl 7 on the mixing bowl 6 with the claws 5 open and in 10 the chopper bowl 7 that has just been placed on the mixing bowl 6 with the mixing bowl 6 tilted forward. The shaft end 36 protruding from the mixing bowl is not fully inserted into the drive socket 37.

In the 10 the chopper bowl 7 is still placed at an angle on the mixing bowl lid 3. The claws 5 do not yet grip the mixing bowl lid 3. The conical rear retaining strip 16 has not yet passed under the loop handle 17 . By changing the position in 10 subsequent movement in a clockwise direction, the rear conical retaining strip 16 engages under the loop handle 17 of the food processor 1 according to 8th . When the conical retaining strip 16 is positioned completely under the bow-shaped handle 17, the mixing bowl 6 tilts a little in the direction of the bow-shaped handle 17, and the conical retaining strip 16 is locked under the bow-shaped handle 17. This means that in 1 The right-hand end of the conical retaining strip 16 touches an inner wall of the loop handle 17 and thus prevents the chopper bowl 7 from moving counterclockwise, while the hook 13 grips under the mixing bowl handle 14 and prevents the chopper bowl 7 from moving clockwise, since the hook 13 also moves the mixing bowl handle 14 touched in the operating position. Now according to 8th turn the claws 5 by turning on the food processor 1 and hold the mixing bowl lid 3 on the mixing bowl 6, and the operation can start.

In the 11 , 12 , 13 , 14 and 15 a second embodiment of the chopper supplemental set according to the invention is shown. The second embodiment of the chopper bowl 7 differs from the first embodiment of the chopper bowl 7 only in the design of the cover-side chopper bowl edge 11, otherwise the components are the same and correspond to those in the first embodiment. What was said about the first embodiment also applies to the second embodiment and is also disclosed for this. The chopper bowl rim 11 of the second embodiment is approximately angled in a cross section with a horizontal strip 41 and a vertical strip 42. The chopper bowl rim 11 overlaps the peripheral edge of the mixing bowl lid 3. The chopper bowl rim also points along the horizontal strip 41 surrounding the chopper bowl 7 two opposite closed recesses 43, which are intended for engagement of the claws 5 of the food processor 1, while the vertical strip 42 encompassing the mixing bowl rim completely closes the closed recesses 43 laterally on the mixing bowl rim. The vertical strip 42 is gripped over by the claws 5 along both recesses 43 in the operating state and thus holds the chopper bowl 7 firmly on the mixing bowl lid 3 . The rim of the chopper bowl 7 is placed on the mixing bowl lid 3. However, it does not replace the mixing bowl lid 3. The arrangement of the recesses 43 and the claws 5 is shown in 11 shown. The vertical strip 42 also has an open recess 44 in the area of a tab 45 of the mixing bowl lid 3 . The 11 , 12 and 13 show the arrangement of the chopper bowl 7 on the mixing bowl lid 3.

14 , 15 show the chopper pot 7 of the second embodiment in a plan view and in a perspective side view. The edge of the chopper pot 7 is designed to run all the way around and is dimensioned in such a way that it extends over and around the edge of the mixing pot lid 3 . The horizontal strip 41 has the two closed recesses 43 intended for engagement of the claws 5 of the food processor 1 and having the length of the claws 5 of the food processor along a circumferential direction. The chopper pot edge 11 also has the vertical strip 42, which adjoins the horizontal strip 41 on the outside and also runs around the chopper pot 7 and also completely closes off the two closed recesses 43 on the outside. In the operating state, the claws 5 enclose the vertical strip 42 in the section of both closed recesses 43. The open recess 44 in the horizontal strip 42 is provided in order to enclose the tab 45 of the mixing bowl lid 3. An inner contour of the chopper bowl rim 11 is adapted to the outer contour of the rim of the mixing bowl lid 3. There is preferably full-surface contact. A line of contact between the horizontal strip 41 and the vertical strip is therefore slanted.

In the 16 , 17 , 18 , 19 a third embodiment of the chopper pot set according to the invention and the chopper pot 7 is shown. The third embodiment differs from the first and second embodiment only in the chopper bowl edge 11 of the chopper bowl 7 . The chopper pot 7 is also placed on the existing mixing pot lid 3 in the third embodiment.

The 18 and 19 show that the chopper pot rim 11 forms the horizontal strip 41 running around in sections, with two recesses 46 being provided, which in turn have the extension of the two claws 5 in the circumferential direction and allow the claws 5 to engage. On one portion of the horizontal strip 41 is the hook 13 and on another portion of the horizontal strip 41 opposite the hook 13 a rear tab 47 is formed. The mode of operation corresponds approximately to that of the first embodiment.

The hook 13 reaches under according to 16 the mixing bowl handle 14 in the operating state and hits one side of the mixing bowl handle 13 when the claws 5 lock the mixing bowl lid 3 in place. At the same time, the lug 47 grips the bow handle 17 without locking it on the bow handle 17 . The flag 47 only serves to prevent the chopper bowl 7 from lifting off the mixing bowl lid 3 . A rotational movement of the chopper pot 7 on the mixing bowl lid 3 is prevented by the radial edges of the recesses 46, which abut against the closed claws 5 when the chopper pot 7 is rotated and prevent a rotational movement. Therefore, the length in the circumferential direction of the recess 46 corresponds exactly to the length of the contact points of the claws 5 with the mixing bowl lid 3.

In the 20 until 22 a fourth embodiment of the chopper bowl 7 according to the invention is shown. Here, too, the chopper extension set differs from the other embodiments only by the chopper bowl 7, and the chopper bowl 7 differs from the other embodiments only by the chopper bowl rim 11 of the chopper bowl 7 formed vertical strips 42 and intended to be placed directly on the peripheral upper edge of the mixing bowl 6. To do this, the mixing bowl lid 3 placed on the mixing bowl 6 is removed and replaced with the chopper bowl 7. In the operating state, the claws 5 then grip the surrounding chopper bowl rim 11 and hold the chopper bowl 7 directly on the mixing bowl 6 .
