Description

[0001] The present invention relates to a kitchen appliance assembly comprising a kitchen appliance assembly and a chopping assembly. To provide a chopping operating mode of the kitchen appliance assembly for chopping foodstuffs such as vegetables and / or fruit, the chopping assembly and the kitchen appliance assembly are assembled into an operating mode structure. Kitchen appliances for chopping foodstuffs are known from EP 2 382 902 A1 and DE 20 2021 105 193 U1.

[0002] In the present context, a “food processor” may also be referred to as a “food processor assembly”.

[0003] Chopping foods such as vegetables (e.g., zucchini), fruit (e.g., apples), and even potatoes is naturally very labor-intensive, especially when done manually using a knife or other hand-operated chopping tool. Such manual chopping of food is time-consuming, poses a risk of injury to the user, and is associated with a limited variety of shapes (of the chopped food). Electric kitchen appliances are also known that can be used to chop food, for example, to slice potatoes. The disadvantage of such electric kitchen appliances, which are limited to a specific functionality, is that they require additional space in the kitchen for storage.

[0004] Furthermore, multifunctional kitchen appliances, such as those sold under the Thermomix® brand, can also be used for chopping food, in addition to other functions (e.g., heating, mixing). Reference is made in this regard to publication EP 3 936 014 A1, for example. The design therein utilizes the rotational function of a mixing tool arranged in a food preparation vessel to transfer the rotational movement performed by the mixing tool to a cutting disc via an adapter. For chopping, food can then be brought into contact with the rotating cutting disc. If the lid is not in place, a user may come into contact with the cutting disc attached to the adapter (even if the cutting disc does not rotate when the lid is not in place). There is therefore a need to further improve the safety of such kitchen appliances.

[0005] There are also known kitchen appliances where, even when a chopping tool (e.g., a cutting disc) is rotating, direct contact between a user and the rotating chopping tool cannot be ruled out. Accordingly, there is a fundamental need to improve the operational and user safety of kitchen appliances used for chopping food.

[0006] Kitchen appliance assemblies can form a kitchen appliance arrangement with corresponding shredding assemblies (including, for example, a shredding tool).

[0007] The object of the present invention is, on the one hand, to provide an alternative to known kitchen appliance assemblies. On the other hand, a further object is to improve the operational and user safety of kitchen appliance assemblies when chopping food.

[0008] The invention is solved by a kitchen appliance arrangement having the features of claim 1.

[0009] Firstly, the present invention relates to a kitchen appliance arrangement comprising a kitchen appliance assembly and a chopping assembly, wherein, in order to provide a chopping operating state of the kitchen appliance arrangement for chopping foodstuffs such as vegetables and / or fruit, the chopping assembly and the kitchen appliance assembly are assembled into an operating state structure.

[0010] The kitchen appliance assembly includes: a. a drive unit; b. a rotatably mounted rotation unit which, in the operating state configuration, is rotatable using the drive unit, wherein the rotation unit is a mixing knife;

[0011] The shredding assembly includes: c. a collecting pot for collecting chopped food, the collecting pot having a collecting pot interior which is delimited on the outside by a collecting pot base and a collecting pot shell, wherein in the operating state structure a collecting pot opening opposite the collecting pot base is covered with a collecting pot lid; d. an adapter shaft which, in the operating state configuration, is coupled to the rotation unit with a first adapter shaft end, so that a rotation of the rotation unit is transmitted directly to the adapter shaft, wherein the adapter shaft, in the operating state configuration, extends into the collecting pot interior with a second adapter shaft end opposite the first adapter shaft end, wherein an adaptation interface is formed in the region of the first adapter shaft end, which is supported on the rotation unit, e. a support shaft separate from the adapter shaft, which is received with a first support shaft end in the collecting pot lid in an axially displaceable manner with respect to a support shaft longitudinal axis and is rotatably mounted about the support shaft longitudinal axis, namely even when the shredding assembly is not assembled with the food processor assembly to form the food processor arrangement, wherein the support shaft has a second support shaft end opposite the first support shaft end, which is coupled to the second adapter shaft end in the operating state configuration, so that a rotation of the rotation unit and the adapter shaft is transmitted directly to the support shaft; f. a comminution tool which, in the operating state, is carried by the carrier shaft and arranged in a rotationally fixed manner to it.

[0012] The aforementioned "operating state configuration" can be understood as the assembled state of the food processor assembly and the shredding assembly into a common unit, in which operation of the food processor assembly for shredding food is enabled. The operating state configuration can refer to a standby mode, a switched-off mode, or an active operating mode (in which food is actively shredded) of the food processor assembly. If the food processor assembly and the shredding assembly are not assembled (into a common unit), food cannot be shredded using the food processor assembly.The features described below refer to a functional, assembled operating configuration of the food processor assembly and the shredding assembly, in which the shredding of food is enabled by the rotation of the rotating unit belonging to the food processor assembly. The rotation (and the associated torque) of the rotating unit is transferred to the shredding tool via the adapter shaft and the support shaft. If a food item to be shredded (a product to be shredded) is brought into contact with the rotating shredding tool, it is shredded. The shredding tool can be of modular design, allowing the use of differently designed shredding tools, e.g., for different shredding processes (e.g., cutting, grating, chopping, peeling).

[0013] The food processor assembly can be used for other purposes when not assembled with the shredding assembly. Preferably, the food processor assembly provides a multifunctional food processor on its own or is a component of such a multifunctional food processor. In addition to the drive unit and the rotation unit, the food processor assembly can also comprise other components, such as a control unit. The drive unit preferably drives the rotation unit via a drive shaft.

[0014] With a kitchen appliance arrangement according to the invention, a user is able to chop foodstuffs such as vegetables, fruit or potatoes, in particular to slice, grate, chop, slice, peel, etc., in particular in geometrically defined shapes (e.g. chunky, noodle-like, spiral-shaped, disc-like, strip-like, flake-like, etc.).

[0015] In the described operating configuration, the chopping tool is arranged above the bottom of the collecting pot, meaning that the chopped food falls toward the bottom of the collecting pot after being chopped by the chopping tool and is collected in the collecting pot. After chopping, the food processor assembly consisting of the food processor assembly and the chopping assembly can be disassembled. The collecting pot, together with the chopped food (chopped material) contained therein, can be removed from the assembled structure and used for other purposes. For example, the collecting pot can then be placed in a refrigerator to store the chopped material. The collecting pot can be made of plastic or stainless steel. The collecting pot can also be made of several different materials.A handle or a handle can be arranged on the collecting pot lid and / or the collecting pot casing.

[0016] As mentioned, the shredding assembly comprises an adapter shaft, which, in the operating state, is coupled to the rotating unit by a first adapter shaft end, so that rotation of the rotating unit is directly transmitted to the adapter shaft. The rotating unit transmits torque to the adapter shaft, thus being detachably connected to it in a rotationally fixed (non-rotatable) manner. The rotating unit can be a blade, a mixing blade, or an agitator. An adaptation interface or contact surface formed in the area of ​​the first adapter shaft end rests on the rotating unit. The adapter shaft can be made of stainless steel or plastic, for example.

[0017] As mentioned, the shredding assembly comprises a support shaft separate from the adapter shaft, which is received by a first support shaft end in the collecting pot lid, secured against axial displacement with respect to a support shaft longitudinal axis, and mounted for rotation about the support shaft longitudinal axis. Even if the shredding assembly is not assembled with the food processor assembly to form a food processor arrangement, the support shaft is received by a first support shaft end in the collecting pot lid, secured against axial displacement with respect to a support shaft longitudinal axis, and mounted for rotation about the support shaft longitudinal axis. In this case, the support shaft cannot be separated from the collecting pot lid without the application of force by the user.Since the shredding tool is supported by the support shaft (connected to the collection pot lid) in the operating state, rotation of the shredding tool is only possible when the collection pot lid is placed on the collection pot shell or covers the collection pot opening. Accordingly, the risk of a user being injured by the shredding tool is significantly reduced.

[0018] The embodiments of the kitchen appliance assembly specified in the subclaims are described below. These can be advantageous embodiments of the kitchen appliance assembly in itself, but also of the shredding assembly. The described embodiments can thus be advantageous embodiments of the invention as a whole (even across categories). Also described below are embodiments not specified in the claims. These embodiments can also be advantageous embodiments of the invention.

[0019] According to a first embodiment of the invention, the kitchen appliance assembly can comprise a preparation pot with a preparation pot interior defined on the outside by a preparation pot base and a preparation pot casing. In the operating configuration, a preparation pot opening opposite the preparation pot base is covered with a preparation pot lid. The preparation pot lid has a preparation pot filling opening with a smaller diameter than the preparation pot opening. The rotation unit is arranged near the preparation pot base. Many well-known kitchen appliance assemblies (e.g., the Thermomix® 5, 6, and 31 from the manufacturer Vorwerk and the Monsieur Cuisine kitchen appliance sold by the retailer Lidl) include such a preparation pot.The shredding assembly can therefore be combined with preparation pots from different manufacturers and can interact functionally with them.

[0020] According to a further embodiment of the invention, it can be provided that, in the operating state, the collecting pot is placed on the preparation pot lid of the preparation pot, in particular such that a preferably cylindrically shaped collecting pot collar arranged on an underside of the collecting pot base rests on the preparation pot lid, and / or that the underside of the collecting pot base rests on a preferably cylindrically shaped preparation pot lid collar arranged on the preparation pot lid. The cylindrically shaped collecting pot collar and / or the cylindrically shaped preparation pot lid collar can have a circumferentially continuous cylindrical shape or have material perforations, i.e., be composed of a plurality of webs forming the respective collars. The collecting pot collar can form a base for the collecting pot.It can be provided that the collection pot collar rests at least partially on the preparation pot lid collar, or vice versa, thus providing a radial locking mechanism for the collection pot relative to the preparation pot. The support is provided by the corresponding outer surfaces of the respective collars. Placing the collection pot on the preparation pot enables particularly simple assembly (connection) of the collection pot to the preparation pot.

[0021] According to a further embodiment of the invention, it can be provided that an adapter shaft through-opening is formed in the collecting pot base, through which the adapter shaft is guided in the operating state setup, wherein the adapter shaft through-opening is arranged in the operating state setup in the radial direction centrally to the preparation pot filler opening, and wherein the adapter shaft through-opening has a smaller diameter than the preparation pot filler opening. The adapter shaft through-opening is preferably a hole opening that can have any desired contour geometry (hole geometry), for example, the adapter shaft through-opening can be a hole opening with a cylindrical or polygonal hole geometry. Preferably, the diameter of the adapter shaft through-opening corresponds substantially to an outer diameter of the adapter shaft guided through the adapter shaft through-opening in the operating state setup.If the adapter shaft is tapered along its longitudinal axis, the adapter shaft through-opening has a diameter that is at least equal to or larger than the largest outer diameter of a longitudinal section of the adapter shaft passing through the adapter shaft through-opening in the operating state. The adapter shaft through-opening and the adapter shaft are preferably designed so that the shredded material collecting in the collection pot does not enter the preparation pot. Therefore, the preparation pot does not require separate cleaning after shredding.

[0022] According to a further embodiment of the invention, the adapter shaft, in the operating state, extends from the first adapter shaft end coupled to the rotation unit through the preparation pot interior and the adapter shaft through-opening into the collection pot interior, with the second adapter shaft end terminating in the collection pot interior. With respect to the overall structure of the kitchen appliance assembly, the adapter shaft is thus preferably arranged and positioned centrally.

[0023] According to a further embodiment of the invention, a fastening collar can be formed on the underside of the collecting pot base—in the radial direction between the adapter shaft through-opening and an outer peripheral edge of the collecting pot base—which extends cylindrically from the underside of the collecting pot base away from the underside of the collecting pot base. The fastening collar can have a continuous cylindrical shape or have material perforations, i.e., it can be composed of a plurality of fastening webs forming the fastening collar, which are arranged in a circle at a distance from one another. The fastening webs then form a cylindrical series of fastening webs, wherein the fastening webs do not touch one another.

[0024] According to a further embodiment of the invention, it can be provided that the fastening collar is designed and dimensioned such that it engages in the preparation pot filling opening in the operating state, wherein fastening means are arranged on the fastening collar which, when the fastening collar engages in the preparation pot filling opening, provide security against axial displacement of the collecting pot relative to the preparation pot. This prevents unwanted detachment or rapid movement of the collecting pot from the preparation pot during chopping of the food, which significantly contributes to user and operational safety. As such, the fastening collar, when engaged in the preparation pot filling opening, also provides security against displacement of the collecting pot in the radial direction, namely relative to the preparation pot.This prevents the collection pot from moving or loosening relative to the preparation pot, even in the radial direction.

[0025] According to a further embodiment of the invention, the fastening means can be provided as a plurality of locking lugs formed on the fastening collar, which lock with the preparation pot lid when the fastening collar engages in the preparation pot filling opening, and / or wherein the fastening means are means for providing bayonet locking connections, which form bayonet locking connections when the fastening collar engages in the preparation pot filling opening with the preparation pot lid. A corresponding fastening means (locking lug or means for providing bayonet locking connections) can be formed on one or more of the aforementioned fastening webs. These fastening means can also be formed on a fastening collar formed in a continuous cylindrical shape. The fastening means enable axial and / or radial securing of the collecting pot relative to the preparation pot.

[0026] According to a further embodiment of the invention, it can be provided that a polygonal, in particular hexagonal, outer contour is formed in a contour section at the second adapter shaft end. According to a further embodiment of the invention, it can be provided that the carrier shaft comprises a carrier sleeve which has a first sleeve receptacle at a first carrier sleeve end, which forms the second carrier shaft end and has a polygonal, in particular hexagonal, inner contour. According to one embodiment of the invention, it can be provided that, in the operating state setup, the contour section engages at least partially in the first sleeve receptacle and forms a force-locking and / or form-locking connection with the latter, wherein the outer contour of the contour section corresponds to the inner contour of the first sleeve receptacle.In the case of the interaction of a polygonal outer and inner contour, a positive connection can be provided, which is advantageous for an efficient and safe torque transmission from the adapter shaft to the carrier shaft.

[0027] According to a further embodiment of the invention, it can be provided that the adapter shaft is tapered at least in the region of the contour section in the direction of the second adapter shaft end. If the first sleeve receptacle does not have a tapered shape but rather a constant diameter, a frictional connection can be provided between the contour section and the first sleeve receptacle when the contour section engages the first sleeve receptacle, which makes it more difficult for the carrier shaft to become detached from the adapter shaft in the axial direction and thus significantly contributes to operational and user safety. The frictional connection can be achieved by pushing the first sleeve receptacle onto the contour section or by inserting the contour section into the first sleeve receptacle.Such a force connection also counteracts to a certain extent any twisting between the adapter shaft and the carrier shaft during their rotation, thus contributing to a rotationally fixed connection between the adapter shaft and the carrier shaft.

[0028] According to a further embodiment of the invention, the carrier sleeve can have a beveled run-up section in the region of the first carrier sleeve end, which facilitates coupling of the second carrier shaft end to the second adapter shaft end. In particular, the run-up section facilitates sliding or insertion of the contour section into the first sleeve receptacle. The beveled run-up section thus widens conically toward the contour section and facilitates the positioning of both components, even when initially inclined. To a certain extent, the run-up section thus enables self-alignment between the contour section and the first sleeve receptacle.

[0029] According to a further embodiment of the invention, it can be provided that the support sleeve has a second sleeve receptacle at a second support sleeve end opposite the first support sleeve end, into which second sleeve receptacle a bearing pin with a first bearing pin end is inserted, in particular pressed, in a force-fitting, form-fitting and / or material-fitting manner, wherein the bearing pin with a second bearing pin end opposite the first bearing pin end is received in a bearing receptacle formed in the collecting pot cover in a manner secured against axial displacement with respect to a bearing pin longitudinal axis, which forms part of the support shaft longitudinal axis, and is rotatably mounted about the bearing pin longitudinal axis or the support shaft longitudinal axis. The bearing pin and the support sleeve connected to it can preferably not be easily detached from the collecting pot cover (i.e., without the application of force). The bearing pin can be made of metal (e.g., stainless steel) or plastic.The same applies to the carrier sleeve.

[0030] According to a further embodiment of the invention, the comminution tool can be a cutting disc that is rotationally fixedly connected to a cutting disc carrier sleeve that projects centrally through the cutting disc. In the operating state, the cutting disc carrier sleeve is releasably pushed onto the carrier sleeve and secured against axial displacement relative to the longitudinal axis of the carrier shaft by locking means arranged on the carrier sleeve. When pushed onto the carrier sleeve, the cutting disc carrier sleeve is rotationally fixedly connected to the carrier sleeve. The cutting disc carrier sleeve can have a polygonal (e.g., hexagonal) inner contour, while the carrier sleeve can have a polygonal (e.g., hexagonal) outer contour.Accordingly, when the cutting disc carrier sleeve is pushed onto the carrier sleeve, a positive connection (between the polygonal contours) can provide the rotationally fixed connection between the cutting disc carrier sleeve and the carrier sleeve. In this context, a detachable connection between the cutting disc carrier sleeve and the carrier sleeve means that the cutting disc carrier sleeve, including the cutting disc, can be detached from the carrier sleeve when the shredding assembly is not mounted (assembled), yet is secured against axial displacement when in use in the operating state. A rotationally fixed connection between the carrier sleeve and the cutting disc carrier sleeve pushed onto it is also preferably ensured. This can be achieved, in addition to the described interaction of the polygonal contours, for example, by a force-locking connection (e.g., a press fit) between the cutting disc carrier sleeve and the carrier sleeve or by the aforementioned locking means.The cutting disc preferably has at least one cutting edge and at least one corresponding cutting opening through which the chopped food can fall through the cutting disc in the direction of the collecting pot.

[0031] According to a further embodiment of the invention, the collecting pot lid can be provided with a filler neck through which food to be chopped can be pressed (moved) towards the cutting disc using a plunger that can be inserted into the filler neck. The filler neck extends from a surface of the collecting pot lid facing the outside of the collecting pot and forms a filling channel that opens into the interior of the collecting pot. The plunger is generally used manually by a user to press the food towards the cutting disc or to feed food. The combined use of the filler neck and plunger further reduces the risk of injury to the user from the rotating shredding tool.

[0032] According to a further embodiment of the invention, the collecting pot shell can have, on its inner surface facing the collecting pot interior, one or more webs extending at least partially in a direction from the collecting pot base to the collecting pot opening and projecting into the collecting pot interior, wherein the web(s) prevent the cutting disc carrier sleeve connected to the cutting disc from accidentally being placed on the second adapter shaft end. The web(s) reduce(s) the inner diameter in the collecting pot interior such that a cutting disc with a larger outer diameter relative to the inner diameter of the collecting pot interior defined by the webs cannot be placed on the second adapter shaft end and operated. This has a positive effect on the safety of a user of the kitchen appliance arrangement.

[0033] According to a further embodiment of the invention, the carrier sleeve can have a circumferential bearing edge at a second carrier sleeve end opposite the first carrier sleeve end. This bearing edge is received in a bearing slot formed in the collecting pot cover in a manner secured against axial displacement with respect to the longitudinal axis of the carrier shaft and is mounted rotatably about the longitudinal axis of the carrier shaft. This embodiment ensures, on the one hand, secure mounting of the carrier sleeve (and thus also of the comminution tool) in the collecting pot cover with respect to axial displacement, and, on the other hand, allows rotation of the carrier sleeve relative to the collecting pot cover, which remains in a fixed position during operation.

[0034] According to a further embodiment of the invention, the carrier sleeve can have a funnel-shaped section tapering from the bearing edge towards the first end of the carrier sleeve, wherein a receiving slot for a comminution tool is formed at a lower end of the funnel section, and wherein, in the operating state configuration, a comminution tool is inserted into the receiving slot. Different comminution tools can be inserted into the receiving slot in a slide-like manner. Means for securing a positionally and rotationally fixed arrangement of the comminution tool with respect to the funnel section of the carrier sleeve can be provided in the region of the receiving slot and / or on the comminution tool.In particular, this embodiment is a variant of the shredding assembly with which vegetables, fruit, and / or potatoes can be shredded (cut) in a spiral or noodle-like manner. According to a further embodiment of the invention, this variant can also be provided for the collecting pot lid to have a filler neck. In the operating state, this filler neck is aligned with the funnel section. In the operating state, the food to be shredded can be pushed through the filler neck toward the funnel section and the shredding tool using a plunger that can be inserted into the filler neck.

[0035] According to a further embodiment of the invention, an anti-twist device can be arranged on an outer surface of the collecting pot casing. This anti-twist device has a support flange that, when in the operating state, rests against a tab and / or a handle arranged on the preparation pot lid. This can provide anti-twist protection for the collecting pot relative to the preparation pot or preparation pot lid. The support flange can also be designed such that it rests against a handle or another component of the preparation pot to provide anti-twist protection.

[0036] According to a further embodiment of the invention, one or more cams can be arranged on the support flange, which, when in the operating state, engage under or behind a tab and / or a handle arranged on the preparation pot lid. This can further improve the aforementioned anti-twist protection and / or additionally provide an axial displacement / tilt / radial locking device between the collection pot and the preparation pot.

[0037] Preferably, the support flange is designed such that the shredding assembly can be used in conjunction with the preparation pots of different kitchen appliance models, while simultaneously providing an anti-rotation feature relative to the respective preparation pots. The same applies to the cam(s) arranged on the support flange with respect to the aforementioned axial displacement / tilt / radial locking feature.

[0038] The shredding tool is preferably made of metal.

[0040] Components that are functionally identical or similar (even across individual embodiments) are provided with the same reference numerals.

[0041] Fig. 1 shows a partially sectioned schematic side view of a food processor assembly according to a first embodiment of the invention, in which a food processor assembly and a chopping assembly are assembled to form an operating state structure. The food processor assembly thus comprises a food processor assembly and a chopping assembly, wherein, to provide a chopping operating state of the food processor assembly for chopping foodstuffs such as vegetables and / or fruit, the chopping assembly and the food processor assembly are assembled to form an operating state structure (as shown, for example, in Fig. 1) are assembled.

[0042] The kitchen appliance assembly comprises a drive unit 1 and a rotatably mounted rotation unit 2, which, in the operating state, is rotatable using the drive unit 1. The kitchen appliance assembly further comprises a preparation pot 3 having a preparation pot interior 4 that is delimited on the outside by a preparation pot base 5 and a preparation pot casing 6. In the operating state, a preparation pot opening 7 opposite the preparation pot base 5 is covered with a preparation pot lid 8. The preparation pot lid 8 has a preparation pot filling opening 9 with a smaller diameter than the preparation pot opening 7, and the rotation unit 2 is arranged near the preparation pot base 5.

[0043] The shredding assembly comprises a collecting pot 10 for collecting shredded food, wherein the collecting pot 10 has a collecting pot interior 11 which is delimited on the outside by a collecting pot base 12 and a collecting pot shell 13, wherein in the operating state configuration a collecting pot opening 14 opposite the collecting pot base 12 is covered with a collecting pot lid 15.

[0044] Furthermore, the shredding assembly comprises an adapter shaft 16 which, in the operating state configuration, is coupled to the rotation unit 2 with a first adapter shaft end 17, so that a rotation of the rotation unit 2 is transmitted directly to the adapter shaft 16, wherein the adapter shaft 16, in the operating state configuration, extends into the collecting pot interior 11 with a second adapter shaft end 18 opposite the first adapter shaft end 17.

[0045] Furthermore, the comminution assembly comprises a support shaft 19 which is separate from the adapter shaft 16 and which is received with a first support shaft end 20 in the collecting pot cover 15 in an axially displaceable manner with respect to a support shaft longitudinal axis TL and is rotatably mounted about the support shaft longitudinal axis TL, wherein the support shaft 19 has a second support shaft end 21 opposite the first support shaft end 20, which is coupled to the second adapter shaft end 18 in the operating state structure, so that a rotation of the rotation unit 2 and the adapter shaft 16 is transmitted directly to the support shaft 19.

[0046] Furthermore, the comminution assembly comprises a comminution tool 22 which, in the operating state, is carried by the support shaft 19 and arranged in a rotationally fixed manner thereto.

[0047] For example in Fig. As shown in Figure 1, in the operating state, the collection pot 10 is placed on the preparation pot lid 8 of the preparation pot 3. A cylindrical collection pot collar 23 is formed on an underside 24 of the collection pot base 12. The underside 24 of the collection pot base 12 rests on a cylindrical preparation pot lid collar 25 arranged on the preparation pot lid 8.
