Description

The invention relates to a kitchen appliance for processing pieces of food according to claims 1, 6 and 8 and a set with such a kitchen appliance and several tool inserts.

In catering establishments and for private users, pieces of food have to be cut regularly when preparing meals. This often means a lot of work, especially when special cuts such as spiral cuts, strip cuts or the like have to be made.

Cutting devices have been proposed in which a piece of food to be cut is inserted individually by hand into the cutting device and attached to a holder, and the cutting process is then manually triggered. the EP 2 815 858 A1 describes such a device with a manually operated lever to drive individual potatoes, which have previously been manually pressed onto a driven drive plate, against fixed blades. Such devices regularly require a lot of space and also generally allow little or no automation of the cutting process. In addition, the cuts are often limited. Such cutting devices are therefore often inflexible in use.

the DE 10 2016 108 440 A1 describes a cutting device that enables a wide variety of cutting shapes and very good cutting results, while at the same time exhibiting a high degree of automation.

It is also often desirable to press fruit to make juice.

Another common and time-consuming task is peeling pieces of food. To make fresh French fries, for example, potatoes are first peeled in a first step and then cut into strips in a second step. Both steps are typically performed by hand or with the help of various kitchen appliances.

The object of the present invention is to provide a further improved kitchen appliance.

This object is achieved by a kitchen appliance for processing pieces of food having the features of claim 1.

According to this, the kitchen appliance comprises a housing with a tool holder, on (in particular in) which a tool insert is mounted and / or can be mounted. The kitchen appliance further comprises a drawer with several receptacles for receiving pieces of food, the drawer being arranged displaceably on the housing in such a way that one of the plurality of receptacles is selectively aligned with a tool insert mounted on (in particular in) the tool receptacle. Furthermore, the kitchen appliance comprises a drive which is designed to press (and optionally to rotate) a piece of food arranged in the receptacle aligned with the tool insert against the tool insert mounted on (in particular in) the tool receptacle.

This arrangement enables particularly flexible use of the kitchen appliance, the drawer with the multiple receptacles allowing particularly efficient processing of a large number of pieces of food.

Optionally, several slats are arranged on each of the receptacles in the drawer. The lamellas are designed, for example, to hold a piece of food arranged in the respective receptacle, in particular to hold it in the middle of the receptacle. This enables the piece of food to be placed in a simple manner in such a way that it can be pressed precisely against the tool insert. This enables particularly precise cutting results and, moreover, the amount of waste can be reduced.

In one embodiment, the drawer is arranged displaceably along a sliding axis on the housing. Optionally, the sliding axis is aligned perpendicular to a propulsion direction of the propulsion. This enables a particularly simple mechanism. The drawer can be removed, making it easy to clean, for example.

In a further development, the sliding axis is aligned parallel to a level surface when the kitchen appliance with a floor is placed on the surface for use as intended. This enables simple handling.

Optionally, at least one of the receptacles is arranged outside the housing and accessible to a user when another of the receptacles is aligned with the tool insert mounted on the tool receptacle. This makes it possible, for example, to refill one receptacle alternately while the piece of food is processed in another receptacle (if there are exactly two receptacles in the other).

According to one aspect, a kitchen appliance for processing pieces of food is provided, which can optionally be designed according to any configuration described herein can. The kitchen appliance comprises a tool insert comprising a peeling device with several peeling blades, a housing with a tool holder on which the tool insert is mounted and / or mountable, and a drive which is designed to press a piece of food against the tool insert mounted on the tool holder, to peel the piece of food. The peeling blades can be displaced resiliently. Thus, the kitchen appliance can be used for peeling potatoes, for example, and a particularly versatile use is made possible.

In a further development, the multiple peeling blades are arranged concentrically around a common point and / or (in particular in an unloaded state) are each curved in on themselves. For example, each of the peeling blades is made of spring steel and / or is made in one piece, in particular from a piece of spring steel. This enables particularly good peeling results and a robust design.

According to one aspect, a tool insert for the kitchen appliance according to any configuration described herein is proposed. The tool insert comprises a peeling device with a plurality of resiliently displaceable peeling blades which, for example, are arranged concentrically around a common point and / or are each bent and / or are each made of spring steel and / or are made in one piece.

According to one aspect, a kitchen appliance for processing pieces of food is provided, which can optionally be designed according to any configuration described herein. The kitchen appliance comprises a housing with a tool holder on which a tool insert is mounted and / or mountable, a drive that is designed to press a piece of food against a tool insert mounted on the tool holder, a detection unit that is designed to provide an identifier to detect on a tool insert mounted on the tool holder, and a control which is designed to control the advance as a function of the detected identification.

As a result, the advance can be controlled automatically and, depending on the tool insert used, for the respective function of the tool insert in a predetermined manner, in particular in an optimized manner. This enables a particularly versatile and at the same time more efficient and simple use of the kitchen appliance. For example, the propulsion comprises at least one motor, the controller being designed in particular to set a speed and / or a torque of the motor as a function of the detected identification.

Optionally, according to any embodiment described herein, the kitchen appliance comprises a driver that can be moved relative to the housing by the propulsion. The driver is set up to act on the piece of food arranged in the receptacle aligned with the tool insert. The driver optionally comprises several segments that can be moved relative to one another. This enables the segmented driver to lie against the shape of the piece of food, which enables particularly high efficiency when pressing citrus fruits, for example. As an alternative or in addition, the driver comprises one or more skewers for piercing the piece of food in order to take it along in one movement.

According to one aspect, a set is provided, comprising a kitchen appliance according to any configuration described herein and several different tool inserts. A tool bit may comprise a cutting device, e.g., a simple blade, a multi-rib knife, a cutting wire, or a knife net. Alternatively, a tool insert can include, for example, a fruit press, such as a citrus press.

The kitchen appliance 1 includes a housing 10 . The case 10 has an opening 101 to accommodate a drawer 11th on, as well as a tool holder 100 for inserting a tool insert 12A . The opening 101 is in the present case designed as a through opening.

The drawer 11th is in the side of the opening 101 can be pushed in (and optionally also removed), from both sides in the example shown.

At the tool holder 100 in the present case is the use of tools 12A used, however, is the use of tools 12A removable, so that, depending on the type of food pieces to be processed, a suitable one of a plurality of tool inserts is selected and inserted into the tool holder 100 can be used. Alternatively, it could also be provided that a specific tool insert is permanently mounted.

Is the kitchen appliance 1 on a level surface U , then is the drawer 11th above the tool holder 100 arranged. Below the tool holder 100 is a catchment area 102 provided in which after 1 a collecting container 13A is arranged.

The drawer 11th forms at least one recording A1 , in the example shown, two recordings A1 , A2 (please refer 2 ) out. In each of the recordings A1 , A2 is a piece of food L. applicable. If one of the recordings A1 , A2 in the housing 10 arranged and on the tool insert used 12A is aligned, then the other recording is standing A1 , A2 out of the case 10 emerged. This means that the piece of food can always L. in the recording A1 , A2 inside the case 10 can be processed while at the same time the external recording (here the recording A1 ) can be refilled.

Each of the recordings A1 , A2 is with a large number of slats 110 Mistake. The lamellas are here 110 in this way (circumferentially in the example shown) on the inner walls of the respective receptacle A1 , A2 attached so that it extends radially to the center of the receptacle A1 , A2 extend towards. The slats 110 are flexible. The flexibility of the slats 110 is designed so that when inserting a piece of food L. the slats 110 away from the center, towards an inner wall of the receptacle A1 , A2 are pressed and thereby a clamping force on the piece of food L. exercise that the piece of food L. centered in the recording A1 , A2 holds. Optionally, the slats 110 make a bend so that it differs from its extension from the inner wall to the center of the receptacle A1 , A2 Bend (slightly) away from the center. This can prevent the slats 110 with the piece of food L. jam. The slats are optional 110 Can be removed individually or together, for example for cleaning purposes. The drawer 11th can be removed as a whole and is therefore easy to clean.

In the case 10 a drive is housed, which will be described in more detail below. The advance pushes a piece of food L. along a direction of advance V in one on the tool insert used 12A aligned recording A1 , A2 against the use of tools 12A . This will make the piece of food L. according to the use of tools 12A processed, e.g. cut, pressed or grated. The processed food then falls into the collecting container 13A .

The direction of advance V points perpendicular to the ground U towards the ground U . The drawer 11th is along a sliding axis S. in the opening 101 movable. The sliding axis S. runs perpendicular to the feed direction V .

2 shows the kitchen appliance 1 with another inserted tool insert 12B. The differences in the tool inserts 12A , 12B are further below with reference to 4th will be explained in more detail. The use of tools 12B out 2 includes a citrus press. Fruits to be pressed, for example oranges, can, for example, cut in half into the receptacles A1 , A2 be used so that it is possible to use this with the kitchen appliance 1 to press. In 2 is a collecting container 13B shown in the form of a drinking vessel.

3 shows the drawer 11th and the one in the housing 10 arranged advance 15th , with the remaining parts of the kitchen appliance 1 are not shown. The two recordings are particularly recognizable A1 , A2 the drawer 11th with the slats 110 . According to 3 is the recording shown on the right in the figure A1 on the propulsion 15th aligned (and accordingly to the in 3 tool insert not shown).

The advance 15th includes one fixed to the housing 10 connected spindle 150 engaged with a spindle nut 151 stands. The spindle nut 151 is stuck with a carriage 154 connected. The car 154 has an external toothing with a pinion 152 combs. The pinion 152 is through one in the housing 10 attached engine 153 (in particular electric motor) can be driven. Will the engine 153 activated, the pinion can rotate 152 a rotation of the carriage 154 and as a result of the engagement of the spindle nut 151 with the spindle 150 also an advance of the carriage 154 effect (depending on the direction of rotation in the direction of the recording A1 or opposite). An (optional) further motor 155 (in particular electric motor) is designed to the spindle 150 relative to the housing 10 to rotate. For example, it will be the pinion 152 driving motor 153 held and the other engine 155 rotates, then the carriage 154 depending on the direction of rotation of the other motor 155 extended or retracted without rotating. By activating both motors 153 , 155 the direction of travel, direction of rotation, driving speed and speed of rotation can be set. Depending on how the pieces of food are processed L. can thus optimize the movement of the car 154 be effected.

One at the front end of the cart 154 arranged driver 16 comes into the holder at a feed A1 in contact with a piece of food placed therein L. and presses it against the tool insert. The driver 16 is designed, for example, in the form of a disc and can have a structured surface and / or skewers and / or edges for taking away the pieces of food L. .

There are other configurations of propulsion 15th conceivable, but in general terms it can be provided that the propulsion 15th is set up for this purpose, with an adjustable advance speed and an adjustable rotation speed (in particular independently of the advance speed) to one in the respective receptacle A1 , A2 arranged piece of food L. to act.

4th shows the kitchen appliance 1 in a set with several tool inserts 12A-12E . The set includes at least two, more than two or all of the tool inserts 12A-12E . Depending on which type of processing is desired, the respective tool insert 12A-12E in the tool holder 100 can be used.

4th shows a tool insert 12A in the form of a spiral cutter with an eccentric to the axis of rotation of the driver 16 arranged cutting blade. The carrier rotates 16 with simultaneous feed, a piece of food is pushed against the cutting blade while rotating and thus cut into a spiral. Such a tool insert 12A is in 4th exemplarily in the kitchen appliance 1 used.

A tool insert 12B includes a citrus press. For this purpose the advance 15th advanced with a slight twist.

Another use of tools 12C comprises a peeling device 121 , which will be explained in more detail below. With this tool insert 12C for example potatoes can be peeled. For this purpose, the potatoes are slowly pushed forward, for example with a strong twist.

Another use of tools 12D includes a corrugated knife with which, for example, parmesan cheese can be grated. For this purpose, a rotation with a particularly low feed rate can be set.

Another use of tools 12E includes a cutting net for cutting French fries. Becomes the driver 16 without a rotation advanced, this cutting insert can be used to cut straight French fries.

It can be seen that depending on the use of tools 12A-12E different feed speeds and different rotational speeds (up to a standstill of the rotation) can lead to optimal results.

Each of the tool inserts 12A-12E includes a marking 120 . The marking 120 identifies the type of tool use 12A-12E . The marking 120 is optionally an optically readable barcode, an RFID chip, or a mechanical coding, for example in the form of a characteristic projection or embossing. The kitchen appliance 1 further comprises a detection unit 14th for labeling 120 . The registration unit 14th is on the housing 10 arranged and designed to mark the 120 read, e.g. optically, electromagnetically or mechanically. The registration unit 14th is communicative with a controller 17th coupled which the propulsion 15th (specifically the engine or engines 153 , 155 of the advance 15th ) controls. The control thus recognizes 17th automatically the tool insert used 12A-12E and controls the advance based on this 15th on. In particular, the controller 15th based on the tool used 12A-12E Feed rate and / or speed of rotation of the driver 16 to adjust. Are optional for each tool application 12A-12E predefined setting parameters for the advance 15th and are saved by capturing the identification 120 selected and set accordingly. Alternatively, the marking includes 120 Information on setting parameters that the control 17th by means of the registration unit 14th can read out.

This allows manual adjustment of the propulsion 15th omitted, which allows a particularly comfortable handling with optimized processing results at the same time, furthermore a particularly versatile use of the kitchen appliance 1 for a variety of different types of processing.

5A-5E and 6th show the peeling device 121 of tool use 12C in greater detail. The peeling device 121 includes a ring 122 with multiple pens 123 (see in particular 6th ). The pencils 123 are equidistant on the ring 122 arranged. On each of the pens 123 is a peeling blade 124 attached.

Each of the peeling blades 124 is made from an elongated piece of spring steel. Each of the peeling blades 124 exhibits a resilient Bracket portion on, the form-fitting on the respective pin 123 is held and spirals around the pen 123 extends. Proceeding from this, each of the peeling blades has 124 a peeling section which is bent over several times (alternatively is continuously provided with a curvature along its length). These bends are bent against the spiral shape. The bends at the free end of the peeling blades 124 describe a larger angle (with respect to a straight extension) than the bends arranged closer to the mounting section. This shape enables particularly good peeling results. The peeling blades 124 are concentric about a center point of the ring 122 arranged. In the relaxed state (see 5A and 5B) are the free ends of the peeling blades 124 located near the center.

Becomes a piece of food to be peeled L. through the ring 122 the peeling device 121 driven, then displaces the piece of food L. the individual peeling blades resiliently outwards towards the ring 122 (please refer 5C and 5D , such as 5E) . Here is the piece of food L. peeled off.

7A and 7B show a driver 16 ' for the kitchen appliance described above 1 . The driver 16 ' comprises several segments 160 . The segments 160 are movable relative to each other. For example, each of the segments is 160 designed in the form of a beam. Here are the segments 160 arranged in a grid. It should be noted that the segments 160 also from the in 7A and 7B The shape shown by way of example can differ and that also a (significantly) larger or smaller number of segments 160 can be provided. The segments 160 have different lengths from one another. The centrally arranged segments 160 are the shortest here, while the segments arranged on the outside 160 are the longest. The segments 160 can be inserted into the in 7A and 7B The starting position shown are pushed into which the piece of food L. facing front sides of the segments 160 together, for example, describe a flat surface.

Becomes the driver 16 ' against a piece of food L. pushed, then optionally initially optional skewers161 penetrate the piece of food L. one. With a (further) advance, the segments lay down 160 to the shape of the piece of food L. at, with edges of the segments 160 the piece of food L. can also hold on. In this way, for example, an orange or the like can be pressed particularly efficiently against the press.
