This application claims benefit of European Application No. 21185463.3, filed on Jul. 14, 2021, the disclosure of which is hereby incorporated in its entirety by reference herein.
A food preparation appliance is an appliance for a kitchen, i.e. a kitchen appliance. The food preparation appliance comprises a preparation vessel in which the food can be prepared. The food preparation appliance may comprise a lid for the preparation vessel. The food preparation appliance may comprise a locking device for locking the lid when the lid is placed on the preparation vessel. The food preparation appliance may comprise a sensor which is triggered when the locking device locks the lid in place. The food preparation appliance comprises the cutting device.
A kitchen appliance with a cutting device is known from the publication EP 3 427 621 A1. The cutting device comprises a rotatable cutting disc with which a food product can be chopped.
Electrically operated kitchen appliances with a preparation vessel and a lid for the preparation vessel are known from the publications DE 10 2014 111 193 A1 and DE 10 2017 121 946 A1.
The present disclosure is directed to a cutting device with which chopping can be performed particularly uniformly.
The cutting device comprises a rotatable cutting disc with friction and/or cutting elements. The cutting disc is basically a circular body whose radius is many times greater than its thickness. For stability reasons, the cutting disc basically consists of metal. Cutting elements of the cutting disc comprise sharp edges for cutting food products. Friction elements can be protruding teeth or pins. The teeth or pins may be pointed and/or sharp-edged.
The cutting disc is attached to a shaft or can be detachably attached to the shaft. In order to save space without great effort when storing the cutting device, the cutting disc can preferably be detached from the shaft without having to use tools. The shaft may consist of plastic to keep the manufacturing costs and weight low.
The cutting device comprises a filling neck via which a food product can be fed to the cutting disc. If a food product is fed to the cutting disc via the filling neck and the cutting disc rotates, the fed food product is chopped.
The filling neck comprises two chutes. A food product can be fed to the cutting disc via each chute. The two chutes are separated from each other by a partition (dividing wall).
The partition is basically closed and basically has a smooth surface. The wall of the filling neck is also basically closed. At least the inside of the wall of the filling neck is preferably smooth. Smooth walls allow a food product to pass through each chute as unhindered as possible. Closed walls prevent a food product from leaving a chute unintentionally through side openings.
The figuresshow:
The two plungers 1 have different shapes and sizes when viewed in plan view. The height of the two plungers 1 is the same.
The chutes 6 and the filling neck are connected at their lower side to a curved cap 7 in an edge region of the cap 7. On the lower side of the cap 7, part-circular steps 8 are provided on two opposite sides. The two part-circular steps 8 protrude laterally and downwardly from the cap 7.
A mandrel 9 protrudes upwardly from the cap 7 from approximately the center of the cap 7. The mandrel 9 retains a rod 10 protruding downwardly relative to the cap 7. The outer diameter of the mandrel 9 is larger than the maximum outer diameter of the rod 10 for stability reasons. The rod 10 may have a cylindrical widening 11 at its free end with a tapering free end 12. The lower side of the steps 8 may be designed as a hook shape 13.
In
When the two plungers 1 are inserted into the chutes 6, the pressing means is held in a clamped manner in the end position. This is achieved because the width of the gap 4 tapers towards the circumferential edge 2 and the thickness of the partition 14 is selected such that the partition can finally be held frictionally through the gap 4, The frictional connection is just large enough to prevent the filling neck from falling out of the cover 5 when the cover 5 is turned around. If the cover 5 is released after chopping, the pressing means can then advantageously not fall out of the chutes 6 in an unplanned manner. Producing the tapered shape is possible by injection molding. and this can also be done by taking advantage of warpage that can occur during injection molding. However, a suitable taper can still be produced following injection molding.
In
In
There are hood-shaped cutting elements 19 with an arcuate blade for cutting strips. The hood-shaped cutting elements 19 protrude upwards from the cutting disc 17. Below each hood-shaped cutting element 19 there is a hole leading through the cutting disc, which is passed by a chopped food product. In
There are further a plurality of holes 20. For example, there may be 17 such holes 20 as shown in
The hood-shaped cutting elements protruding downwards from the cutting disc 17 are smaller than the hood-shaped cutting elements 19 protruding upwards from the cutting disc 17. This allows strips of different sizes to be cut from a food product.
The cutting disc 17 comprises a blade 21 which protrudes obliquely upwards from the cutting disc 17. The cutting direction is indicated by an arrow. Below the blade 21 there is a slot through which the chopped food product passes. Seen in the cutting direction, the blade 21 forms an angle of less than 90° with the outer edge of the cutting disc 17. As a result, a food product to be chopped is increasingly conveyed towards the outer edge during chopping. Thus, the upwardly protruding blade 21 acts centrifugally on a food product due to its arrangement when the upwardly protruding blade 21 chops a food product. The blade 21 protrudes from the cutting disc 17 further upwards than the downwardly protruding blade from the slot 18. Thus, thicker slices can be cut by the blade 21 than by the downwardly protruding blade.
If the chutes 6 end on the upper side of the cutting disc 17 shown in
A shaft 22 is detachably attached to the cutting disc 17. The shaft 22 is shaft-shaped, at least partially hollow and has wreath-shaped coupling elements 23 at its ends. The above-mentioned rod 10 can be inserted through the upper coupling element 23 into the shaft of the shaft 22. This stabilizes the position of the shaft 22 during operation in the assembled state of the cutting device, The coupling elements 23 have the same shape. The shaft 22 protrudes equally far from both sides of the cutting disc 17. The cutting disc can therefore also be mounted rotated by 180° so that the chutes 6 then enter at the lower side shown in
The described centrifugal action contributes to stabilize the orientation of a food product during feeding.
The bottom 30 of the vessel 24 has a funnel-shaped opening 29 that opens into a hollow shaft.
In
The shaft 31 has a lower coupling element 33. The lower coupling element 33 can be placed on a mixing tool inside a preparation vessel of a food processor in such a way that the coupling element 33 is connected to the mixing tool in a rotationally fixed manner. Rotation of the mixing tool then results in the cutting disc 17 also being rotated when the shaft 31 is connected to the cutting disc 17 in a rotationally fixed manner.
When the arrn-type locking elements 37 are rotated to their open position, this causes the rocker 38 to move upward by spring force to its non-released position. This movement of the rocker 38 raises the lid part 36 accordingly. The lid part 36 is then placed on the rocker arm 38, but not locked.
When the locking element 37 shown in the upper left of
The coupling element 33 shown in
Instead of the lid part 36, the cutting device can be placed on the preparation vessel 35. This is shown partially in
If the cutting device is placed on the preparation vessel 35 and the cutting disc 17 rotates clockwise as indicated by an arrow in
In
Independent of the direction of rotation and independent of the chute, food products can therefore always be fed to the cutting disc 17 in stable alignment for chopping.
The filling neck and partition may have been produced in one piece in a single step, for example by injection molding. The filling neck and partition may consist of plastic in order to keep production costs and weight low. Each chute runs in particular in a straight line so that a food product can pass through each chute as unhindered as possible.
The partition comprises an indentation when viewed in plan view. Thus, the partition is not straight when viewed in plan view. The partition can be angular and/or arcuate in shape when viewed in plan view.
The indentation prevents a food product in a chute from changing its orientation in a largely unhindered manner. The aim of the indentation is therefore to ensure that the position of the food product changes as far as possible only in the direction of transport. It has been found that this allows a food product to be chopped particularly uniformly. Strongly varying chopping results can therefore be avoided.
The partition may be angular when viewed in plan view. The base of the indentation is then formed by an angle. Advantageously, however, the partition runs in an arcuate shape when viewed in plan view, whereby the alignment of a food product can be stabilized in the chute regardless of its size. This leads to uniform cutting results.
In one embodiment, the partition runs in a circular arc when viewed in plan view. Advantageously, the partition is therefore a partial circle when viewed in plan view in order to be able to chop uniformly in a further improved manner.
In one embodiment, the partition initially encloses an angle of 40° to 80° with at least one wall portion of the chute. Such an angle is particularly well suited to stabilize the orientation also of larger food products when feeding them to the cutting disc.
Preferably, the wall portion is an external wall portion to ensure uniform chopping results in a further improved manner.
In principle, the inlet openings of the chutes are of different sizes in order to be able to stably feed food products of different sizes to the cutting disc in an improved manner.
In one embodiment, the inlet opening of one chute is at least 1,5 times as large as the inlet opening of the other chute, preferably at least twice as large, in order to be able to feed food products of different sizes to the cutting disc in a stable orientation.
In one embodiment, the filling neck is oval when viewed in plan view, in order to be able to achieve the alignment of food products and thus a particularly uniform chopping result independently of the direction of rotation of the cutting disc.
For example, the oval can be composed of two circular arcs and two straight lines.
Advantageously, the two straight lines of the oval run parallel so that the chutes are uniformly wide, which facilitates insertion of a food product into one of the two chutes.
The two arcs are preferably semicircles to allow a smooth transition to parallel walls of the oval. The transition is then free of edges. Among other things, this allows cleaning advantages to be achieved. Semicircles also help to stabilize the alignment of food products particularly reliably during feeding, irrespective of the direction of rotation of the cutting disc.
The oval may be an oval with one or two symmetry axes.
In one embodiment, there is a motor for rotating the cutting disc to perform chopping in a partially automated manner.
In one embodiment, the cutting disc can be rotated both clockwise and counterclockwise by the motor. This makes it possible to achieve different chopping results depending on the direction of rotation.
In one embodiment. the cutting device comprises different cutting elements and/or friction elements.
In one embodiment, the different cutting elements and/or friction elements are oriented differently so that different chopping results can be achieved in a defined manner depending on the direction of rotation.
In one embodiment, the different cutting elements and/or friction elements protrude from both the lower side and the upper side of the cutting disc. The cutting elements and/or friction elements protruding from the lower side differ from the cutting elements and/or friction elements protruding from the upper side. It is possible to select which side faces the filling neck. The cutting disc can therefore be mounted in two different ways. Depending on the side selected, different cutting results can be achieved. If the upper side of the cutting disc faces the filling neck, only the cutting elements and/or friction elements that protrude from the upper side can chop. If, on the other hand, the lower side of the cutting disc faces the filling neck, only the cutting elements and/or friction elements that protrude from the lower side can chop.
With regard to the different cutting elements and/or friction elements, these elements are features that are independent of the indentation of the partition and can therefore be combined with the above-mentioned features independently of this indentation.
To make it particularly easy to select the side of the cutting disc that is to face the filling neck, the shaft is mirror-symmetrical, wherein the cutting disc forms the mirror plane. The shaft at least protrudes equally far from the upper side and the lower side of the cutting disc. If the shaft comprises coupling elements at its ends, these are then the same. This minimizes the assembly work required to mount the cutting disc. This is an independent feature which is independent of the indentation of the partition and can therefore be combined with the above-mentioned features independently of this indentation.
In one embodiment, cutting elements and/or friction elements are arranged or aligned in such a way that they convey a food product centrifugally towards the adjacent outer side of the cutting disc. Thus, there is no conveying parallel to the adjacent outer side of the cutting disc. This stabilizes the orientation of a food product during chopping, which has an effect independently of the indentation of the partition and thus also constitutes an independent feature. In order to develop a centrifugal effect, a cutting edge, viewed in the cutting direction, can enclose an angle smaller than 90°, preferably smaller than 85°, particularly preferably smaller than 80°, with the adjacent outer side of the cutting disc. Alternatively or additionally, cutting elements located on the outside can be arranged offset backwards relative to cutting elements located on the inside, namely in the cutting direction, in order to achieve the desired centrifugal effect. Alternatively or additionally, cutting elements can be arranged in a row in such a way that the row, viewed in the cutting direction, encloses an angle smaller than 90°, preferably smaller than 85°, particularly preferably smaller than 80′, with the adjacent outer side, in order to achieve a centrifugal effect.
In one embodiment, the cutting device comprises a pressing means that can be inserted into the filling neck in order to press food products through the chutes. In particular, the pressing means comprises two plungers which may be non-detachably connected to one another on the upper side. The pressing means may have been produced in one piece from plastic in one work step.
Preferably, the pressing means can be inserted into the filling neck such that the pressing means is held in a clamping manner when the pressing means has been fully inserted into the filling neck. Initially, there is advantageously no clamping effect, so that the pressing means can initially be inserted into the filling neck easily. Thus, the pressing means can advantageously not fall out of the filling neck in an unplanned manner once a food product has been chopped in the maximum possible way. This is an independent feature which is independent of the indentation of the partition and can therefore be combined with the above-mentioned features independently of this indentation.
A clamping effect can be achieved by a slot between two plungers of the pressing means that widens towards the outside and the partition finally being held in a clamping manner by the slot when the pressing means has been fully inserted into the filling neck. Another possibility consists in a chute tapering inwards in such a way that it holds a plunger in a clamping manner when the pressing means has been fully inserted into the filling neck.
In one embodiment, the cutting device is a part of a kitchen appliance or an accessory (add-on part) for a kitchen appliance. The kitchen appliance is in particular a food preparation appliance, with which, thus, a food can be prepared.
A food preparation appliance is an electrical appliance, i.e., an appliance that requires electrical power to operate. A food preparation appliance is an appliance with which at least one step of a food preparation can be performed, such as mixing, chopping, moistening, drying, cooling or heating. Thus, by the food preparation appliance, a food or at least one ingredient of a food can be mixed, chopped, moistened, dried, cooled, and/or heated, for example. A food may be solid and/or liquid. A food may comprise only one food product such as only potatoes. A food may be composed of various ingredients such as carrots, peas, onions, salt and pepper. A food may comprise a liquid such as water or oil.
A food preparation appliance comprises a preparation vessel and, in principle, a lid that can be placed on the preparation vessel. A rotatable mixing tool may be arranged in the preparation vessel. The food preparation appliance may comprise the cutting device as an accessory that can be placed on the preparation vessel instead of the lid, for example. The food preparation appliance may comprise a locking device for locking the lid placed on the preparation vessel and/or for locking the accessory placed on the preparation vessel. The food preparation appliance may comprise a sensor that is triggered when the lid placed on top is locked by the locking device and/or by the accessory placed on top.
Ingredients of a food that are placed directly in the preparation vessel can, for example, be chopped by the rotatable mixing tool. The mixing tool may rotate for this purpose, for example, at at least 5000 or at least 8000 rpm by means of an electric motor. The preparation vessel may comprise heating elements to be able to heat ingredients of a food or a food in the preparation vessel. However, the food preparation appliance may also comprise heating elements for heating the preparation vessel, which are provided separately from the preparation vessel. A base part of the food preparation appliance may comprise a recess that may define the position of the preparation vessel. The recess may be a vessel-like depression into which the preparation vessel may be or is inserted. The receptacle may comprise a drain opening that prevents liquid from accumulating in the recess. In particular, the preparation vessel may be removed from the recess and thus separated from the base part of the food preparation appliance.
The preparation vessel comprises an opening. The lid can be placed on the preparation vessel in such a way that the opening is then covered by the lid at least predominantly, preferably completely.
The accessory differs from the lid in its function. The function of the lid consists in being able to completely or at least largely completely close the preparation vessel. The accessory also contributes to the preparation of a food product in at least another way, since a food product can be uniformly and thus in a defined manner chopped by the accessory. However, the accessory can also assume the function of a lid at the same time, i.e. cover the opening of the preparation vessel at least predominantly. The accessory is therefore also a lid.
A base part of the food preparation appliance may comprise the locking device, which can non-detachably connect the lid and the accessory to the preparation vessel in the locked state. If the food preparation appliance is designed in such a way that the preparation vessel can be detached from the base part, the placing of the lid or the placing of the accessory on the preparation vessel according to the present disclosure requires that the preparation vessel is inserted into the base part. The preparation vessel is then inserted into a recess of the base part, for example.
The base part may comprise a control device, an electric actuator, a sensor, a switch, andior a display.
The device of the present disclosure enables food products to be chopped very uniformly, which is achieved by the indented partition and/or by the centrifugal effect described. Knobs at the pressing means support the stable alignment and thus make a supplementary contribution to uniform chopping. Two chutes of different sizes allow food products of different sizes to be fed in a stable alignment and thus chopped particularly uniformly. Four different cutting elements allow four different chopping results with only one cutting disc. The number of components required is low,
The present disclosure also relates to a component with a filling neck. The filling neck comprises two chutes which are separated by a partition. A food product can be fed to a cutting disc via each chute. The partition comprises an indentation when viewed in plan view. The component may be a cover. The component may be configured as previously described. The component may comprise features of the cover described below, individually or in combination.
