The invention relates to a beverage preparation device, in particular a capsule machine, very particularly preferably a coffee capsule machine for producing beverages, in particular hot and / or cold drinks from beverage substrate capsules (capsules), preferably from coffee capsules according to the preamble of claim 1.
The invention further relates to a method for operating such a beverage preparation device according to claim 15.
In so-called capsule machines in which drinks are prepared by injection of water into beverage substrate capsules, the beverage substrate capsule is usually placed in an open injection chamber, usually a brewing chamber, whereupon the injection chamber, usually closed by a pivot lever movement and thereby the beverage substrate capsule is opened on both sides Water provided on a first side of water supplies, typically injecting hot water and draining the finished beverage opposite.
A distinction is made between so-called closed injection chambers and open injection chambers, in the case of closed injection chambers, the capsule is fully received in the chamber and the injection chamber parts are fully sealed directly against each other, while in the open injection chambers, the injection chamber parts not or only partially against each other, but against the then usually made of hard plastic capsule are sealed, which thus forms a part of the injection chamber.
From the EP 24 05 790 A1 a beverage preparation device has become known in which the beverage substrate capsule is transferred via an oblique chute into an injection chamber part, whereupon the injection chamber is then closed by means of a further, opposite injection chamber part, which is displaced translationally along an adjustment axis onto the injection chamber part having the injection substrate capsule. To adjust this translationally adjustable injection chamber part, a pivot lever mechanism is provided.
A disadvantage of the known beverage preparation devices is felt that the beverage substrate capsule must be fed either manually or via a chute inherently a stationary arranged injection chamber part, whereupon then the injection chamber must be closed by adjusting the other injection chamber part. However, there is a desire for capsule beverage preparation devices in which the positioning of the beverage substrate capsule does not have to be directly in a fixed injection chamber portion, but where the beverage substrate capsule can be spaced therefrom and still ensure proper alignment of the beverage substrate capsule with another, particularly fixed, injection chamber portion is as well as a sufficient or secure locking of the alternatively formed as an open or closed injection chamber injection chamber.
From the EP 2 654 528 B1 a beverage preparation device is known in which a movable injection chamber part is adjustable to a fixed injection chamber part via a complex lever mimic.
For further prior art, the WO 2014/096122 A1 . DE 603 11 772 T2 and the EP 2 205 133 B1 called.
Based on the aforementioned prior art, the invention has for its object to provide a beverage preparation device, in particular capsule machine, in which the beverage substrate capsule does not have to be positioned in a fixed Injektionskammerbauteil, but at a distance to this positionable and still comfortable handling or loading the beverage preparation device and a secure locking of the injection chamber in the closed state, ie is ensured with therein beverage substrate capsule. Furthermore, the object is to provide an optimized operating method for such an alternative beverage preparation device.
This object is achieved with regard to the beverage preparation device having the features of claim 1.
With regard to the operating method, the object is achieved with the features of claim 15.
The invention is based on the idea to assign the first movable or in a, in particular pure, translatory adjustment along the adjustment adjustable, preferably a beverage outlet side forming injection chamber part a beverage capsule, wherein the injection chamber formed by the injection chamber part or arranged on this beverage capsule together with the injection chamber is adjustable, so that along the adjustment axis spaced from the second, preferably stationary, preferably designed as Wassereinleitseite injection chamber with open injection chamber or in befindlichem in the loading position first injection chamber part in the beverage capsule receptacle of the first Injektionskammerteils a beverage substrate capsule can be inserted, which then together with the or in the beverage capsule holder with the first injection chamber part along the adjustment axis in the direction of the second injection chamber part is up to an intermediate position adjustable, wherein it is further provided that an end phase of the closing movement of the injection chamber, preferably only the final phase of the closing movement, not simply by axial or translational sliding of the first injection chamber part is further realized in the direction of the second injection chamber part, but that the final phase of the closing movement, ie the translational e adjusting the first injection chamber part together with the beverage intake from the intermediate position in a further in the direction of the second Injektionskammerteils offset along the adjustment end of a, in particular manually or alternatively electromotively actuated, rotational movement of actuating means of locking and feed means results, ie a rotational movement in convert a translational end adjustment movement of the first injection chamber part along the adjustment axis. In addition, the first injection chamber part is blocked or locked in its end position by the rotational movement of the actuating means about the rotation axis, which preferably coincides with the adjustment axis, such that the first injection chamber part is no longer moved beyond the adjustment axis along the adjustment axis from the end position to the intermediate position. or loading position can be moved out, but the unlocking must be effected by turning back the actuating means.
Overall, the actuating means are adjustable together with the first injection chamber part and its beverage capsule receiving between the loading position and the end position, wherein on this adjustment the actuating means in a region between the intermediate position and the end position are rotatable about a preferably coincident with the adjustment axis of rotation.
In the beverage preparation device according to the invention, it is thus provided that a beverage substrate capsule can be arranged on an adjustable injection chamber part, more precisely on a beverage capsule holder of the first injection chamber part in a loading position, whereupon the first injection chamber part with the beverage capsule holder and beverage substrate capsule arranged therein along the adjustment axis, in particular exclusively by applying a Compressive force is moved purely translationally along the adjustment axis in an intermediate position in the direction of the second injection chamber part and then in a final closing phase, a further translational adjustment of the injection chamber part is effected by rotation or rotation of actuating means whose rotational movement, in particular about the adjustment, in the rest translational adjustment of the first injection chamber part to be converted and by the rotation of which he ste Injektionskammerteil be blocked in its final position against withdrawal or retraction in the direction of the loading, so that the injection chamber is locked or secured and thus can not be opened purely translationally in the injection process only by the acting pressure forces or only by applying a tensile force - for opening a reverse rotation of the actuating means is preferably necessary.
In the beverage preparation device according to the invention, therefore, a loading position and the end position fall apart with an intermediate position arranged therebetween along the adjustment axis, and nevertheless a comfortable handling of the beverage preparation device and a simple locking mechanism of the injection chamber are ensured. It is preferred if the last adjustment path of the closing movement, ie the distance from the intermediate position to the end position along the adjustment axis is shorter, is preferably significantly shorter than the adjustment path from the loading position to the intermediate position, wherein it is particularly preferred if the latter (First) adjustment path or closing path corresponds at least to the axial extent of the beverage substrate capsule along the adjustment axis and is preferably greater than this axial extent to allow comfortable insertion of the beverage substrate capsule, preferably perpendicular to the longitudinal extent of the adjustment axis, while the other (second) adjustment path is preferably shorter as the axial extent of the capsule along the adjustment axis, ie the distance between the capsule faces.
With regard to the concrete design of the injection chamber, there are different possibilities. Thus, it is in principle possible to form the injection chamber as a closed injection chamber, in which the beverage substrate capsule is completely sealed in the end position of the first and the second injection chamber part, which are then fully sealed directly against each other. Alternatively and preferably, an embodiment of the injection chamber as a so-called open injection chamber, in particular not directly in the full extent, the first and the second injection chamber part are sealed against each other, but the two Injektkkammerteile, in particular seal off the end face against the beverage substrate capsule, the latter thus forms a component, so to speak, an intermediate piece of the injection chamber. For this purpose, then preferably supported both injection chamber parts via in each case at least one elastomeric seal, preferably in each case from the front side, on the capsule. Also in the case of the last-mentioned, open injection chamber, it is preferred if the injection chamber parts abut one another in sections, namely in a lower and preferably in a lateral area, in order to avoid uncontrolled water leakage downwards from an area between the injection chamber parts during a rinsing process open injection chamber is characterized in any case by the fact that in the closed position of the injection chamber parts they are not completely sealed against each other, but, in particular on the top of an opening or a larger distance remains. It is essential that the injection chamber parts seal both sealingly against the beverage substrate capsule, which thus forms part of the injection chamber.
The beverage preparation device according to the invention may be formed, for example, for the production of cold drinks, wherein then preferably from the water supply means cold preferably cooled with integral coolants of the beverage preparation device or alternatively ambient temperature having water is injected into the beverage substrate capsule. It is particularly preferred if the beverage preparation device is designed for the production of hot drinks, in particular coffee, in which case preferably hot hot preferably heated with heating means of beverage preparation device water from the water supply means in the beverage substrate capsule is introduced and thus there a substrate can be dissolved and / or leached. The substrate is preferably coffee bean powder which is leached by the injection of hot water.
With regard to the water supply, there are different possibilities. At least in the event that it is preferred that the beverage preparation device has its own water supply, in particular water tank, the water supply means preferably comprise a pump for conveying the water under defined pressure to the injection chamber, in particular to the second injection chamber part. Additionally or alternatively, the water supply means may have a fresh water connection, preferably in combination with a pump. In the case of the formation of the beverage preparation device as a coffee machine for producing coffee, the injection chamber is preferably a so-called brewing chamber and the injection chamber parts are brewing chamber parts, and it is particularly preferred if heating means for heating the water are used to prepare hot drinks in the water supply circuit are integrated.
In principle, it is possible to associate with the actuating means and / or the injection chamber sensor means with which it is possible to detect whether the first injection chamber part is in the end position and / or if the injection chamber is locked, such sensor means preferably being signal-conducting connected to a control device a beverage reference process preferably starts or releases only under the condition that the sensor means a corresponding signal, in particular position signal is obtained.
As explained, the interlocking of the injection chamber is understood to be secured or locked against a purely translational adjustment movement by application of tensile force to the first injection chamber part from the outside and / or by application of pressure to the first injection chamber part in the loading position by water injection into the beverage substrate capsule. In order to enable such a translatory adjustment movement or to be able to adjust the first injection chamber part back into the loading position, the injection chamber must first be unlocked, preferably by rotating the actuating means, in particular into a starting position.
In the last moving section of the injection chamber part for closing the injection chamber, i. when actuated by rotating the actuating means translational adjustment is carried out opening the beverage substrate capsule, in particular on two opposite sides and a sealing pressure, in particular seals for sealing the beverage substrate capsule against the injection chamber parts (open injection chamber) or at least one seal for sealing the first and the second Injektkerkammerteils up to today. It is very particularly preferred if the movement sequence for closing the injection chamber is adjusted so that the capsules are first opened, then the final sealing pressure and preferably in a third step an acoustic and / or haptic feedback of reaching the end position takes place, in particular in that, as will be explained later, an actuating means comprising a rotary sleeve cooperate with corresponding haptic means, in particular spring or latching means in an end rotational position.
For converting the rotational movement of the actuating means about the rotation axis, in particular the adjustment axis, in the translational Endverstellbewegung the first injection chamber part from the intermediate position to the end position and / or in the opposite direction from the end position to the intermediate position, a preferably stationary abutment is provided according to the invention relative to which the first injection chamber part (and beverage capsule receptacle) is adjustable in its translational adjustment, wherein the abutment is arranged relative to the actuating means, which is preferably adjustable together with the first injection chamber part from the loading position to its end position along the adjustment axis, that the actuating means in the intermediate position of the first injection chamber part, the abutment along the adjustment axis, starting from a remote from the second injection chamber part outside of the abutment to one the second Injection chamber part facing inside of the abutment sections or completely and / or encompass, and that the locking and / or feeding means via a, preferably non-rotatably with the Be by means of rotating the actuating means after reaching the intermediate position (starting from the loading position) axially on the inside of the abutment and / or supported on at least one inclined surface such that the rotational movement of the actuating means in the translational Adjusting movement of the first injection chamber part (together with the actuating means and the beverage capsule receptacle) from the intermediate position to the end position is convertible. In other words, the actuation means extend directly from a side of a preferably stationary abutment remote from the second injection chamber part along the adjustment axis to the side (inside) of the abutment facing the injection chamber and are supported on the actuating means, preferably rotationally fixed, fixed or in one piece this formed, in particular arranged on an interaction element support portion on the inside of the abutment in a rotational movement, such that the rotational movement of the actuating means is converted into the translational end adjustment movement of the first injection chamber part of the intermediate position to the end position along the adjustment axis. In order to convert this rotational movement into the translatory adjustment movement, it is necessary for the support section and / or the inner side of the abutment to have an inclined surface along which the support section moves axially along the adjustment axis in the direction of the second injection chamber part during a rotational movement of the actuating means and thus the first injection chamber part adjusted the end position. It is particularly useful if at least one pair of inclined surfaces, preferably two circumferentially spaced inclined surface pairs is / are provided, comprising an oblique surface provided on the support portion and a corresponding inclined surface ab abutment.
The interaction between a aforementioned abutment and the actuating means, in particular a support portion of the actuating means may alternatively be realized in the manner of a threaded connection, ie such that on the actuating means, in particular the first arranged on an interaction element support portion formed first thread, in particular an external thread through Rotating the actuating means after reaching the intermediate position of the first injection chamber part with a formed on the abutment counter thread, in particular an internal thread, cooperates such that the rotational movement of the actuating means about the axis of rotation, in particular the adjustment axis, due to the thread pitch in the desired, in particular pure, translational end -Verstellbewegung the first injection chamber part is converted from the intermediate position to the end position.
As mentioned above, it is particularly preferred if the translational displacement of the first injection chamber part from the loading position to the intermediate position is many times greater than the translational displacement of the first injection chamber part from the intermediate position to the end position, and that the intermediate position is relative to, preferably as Positioning means formed opening means of the beverage preparation device is positioned so that a beverage substrate capsule received in the beverage capsule receiving only on the translational adjustment of the intermediate position to the end position (and not already in the adjustment of the loading position in the intermediate position) on at least one end face, in particular on both facing away from each other Front sides of the beverage substrate capsule for the injection of water and for discharging the finished drink can be opened. It is particularly useful if the adjustment of the loading position in the intermediate position corresponds to at least the axial extent of the beverage substrate capsule along the adjustment axis and preferably greater than this, while preferably the adjustment of the intermediate position to the end position is less than 10mm, preferably less than 5mm and in particular is selected so that in essence the way is sufficient to open the beverage substrate capsule, in particular to pierce and to press an injection chamber seal.
In order to avoid incorrect operation is advantageously provided in a further development of the invention that a rotatability of the actuating means during, in particular total, translational adjustment movement of the first injection chamber part the position is blocked to the intermediate position. This can advantageously be achieved in that the actuating means for blocking their rotatability during the translatory adjustment movement are supported against the abutment in the circumferential direction until reaching the intermediate position, in particular within at least one passage opening of the abutment, which preferably passes through the actuating means along the adjustment axis is.
In particular, in order to enable a retraction of the first injection chamber part along the adjustment axis in the loading position by a Zugkraftbeaufschlagung the actuating means is provided in development of the invention advantageously that the actuating means are mechanically coupled to the first injection chamber component for the transmission of tensile forces. This can be realized, for example, in that the actuating means are rotatably arranged on a later still to be explained frame and secured in the axial direction of this and at the same time the first injection chamber part is fixed to this frame, so that by Zugkraftbeaufschlagung and / or Druckkraftbeaufschlagung the actuating means of the frame together with injection chamber part along the adjustment axis is adjustable. It is preferably a frame with an at least approximately cylindrical envelope contour.
It has been found to be particularly expedient if the first injection chamber part is adjusted in its translatory adjustment movement along a guide frame having two, preferably parallel guide arms, in particular in the manner of a fork, wherein the abutment is designed and arranged as a connecting element between the guide arms, in particular spaced apart from a connecting portion integrally connecting or forming the guide arms. It is particularly useful if the abutment is set only during assembly to the guide arms, in particular form-fitting and not integrally formed with these, in order to position the arms exactly relative to each other in this way. In other words, a tolerance compensation can be realized in this way on the abutment, so that the guide arms are exactly spaced by mounting the abutment to each other. Preferably, the arms are thereby elastically displaced or widened in the outward direction relative to the adjustment axis, so that the distance of the guide arms can be designed to tolerate undersize and the correct spacing is possible by elastic bracing of the abutment.
As already mentioned, it is particularly preferred for the first injection chamber part, in particular for mechanical coupling with the actuating means, to be arranged on a frame, which is guided on the guide arms during the translational adjustment movement of the first injection chamber part, it being possible in principle for this the guide arms guide the frame on its outer periphery. It is particularly useful, however, if the guide arms are axially, i. engage the frame along the adjustment axis, i. are arranged in this and thus the injection chamber part having the frame is guided at its inner periphery.
It is expedient if the actuating means comprise a preferably circular-cylindrical contoured, preferably end-side sleeve bottom, more preferably an outer circumferential grip surface for manual actuation, which preferably engages over the adjustment axis of the abutment in the direction of the adjustment axis, the sleeve element preferably being preferred engages radially inward in an outer circumferential groove of the frame to mechanically couple the sleeve member for transmitting tensile and / or compressive forces with the frame and thus with the first injection chamber part and its capsule receptacle and still relative to the frame, in particular from reaching the To be rotated intermediate position.
It is particularly expedient if in the lateral surface of the above-mentioned sleeve element a circumferentially extending, preferably circumferentially closed, in particular slot-like opening for a beverage outlet is arranged, which is preferably arranged on the first injection chamber part, wherein the opening of the beverage outlet in the radial direction to the outside is permeated and / or can be flowed through by a beverage flowing through the beverage outlet in the radial direction to the outside. As a result, overall the length of the beverage preparation device along the adjustment axis and perpendicular to the adjustment axis can be shortened.
It is particularly expedient if the rotational movement of the actuating means is limited, ie that the actuating means only over a limited (defined) circumferential angle, preferably less than 180 °, even more preferably less than 120 °, most preferably between 60 ° and 100 ° , in particular of 90 °, are rotatable in the circumferential direction about the axis of rotation, preferably coincident with the adjustment axis, in order to displace the first injection chamber part from the intermediate position into the end position and to lock the injection chamber. With regard to the arrangement of corresponding stops, there are different possibilities - it is particularly preferred if the rotational movement by a Stop interaction between the actuating means, in particular a previously mentioned sleeve member and the aforementioned frame for guiding the first injection chamber component along the guide frame is realized.
It is particularly preferred if the actuating means are associated with haptic feedback means which are designed such that they noticeably feedback the achievement of at least one specific rotational position of the actuating means, in particular the achievement of a rotational end position which at least approximately correlates with the end position of the first injection chamber part and / or or an opening position which preferably but not necessarily correlates with the intermediate position of the first injection chamber part. It is very particularly preferred if such haptic feedback means are provided in addition to the rotational movement limiting the actuating means stops, in particular such that the haptic or noticeable feedback occurs shortly before, in particular immediately before reaching or hitting such a stop. To be particularly advantageous, it has been found that the haptic feedback means are formed such that the rotational position of the actuating means, in particular the sleeve member of the actuating means feed back. For this purpose, according to a particularly preferred embodiment of the sleeve member, in particular on an inner circumferential surface of the sleeve member, a first locking element may be provided which cooperates with a preferably frontally arranged on the frame counter-locking element, in particular such that the sleeve-side locking element with a frontal depression and / or a frontal Projection of the frame cooperates and locked with this, in particular after previous sliding over a corresponding ramp. Preferably, the axial play required for the realization of the relative axial movement between the sleeve element and the frame is realized by appropriate sealing dimensions of seals of the beverage preparation device, which are pressed further axially during the latching process, in particular when the sleeve element-side latching element slides along a starting slope of the counter-latching element. It is particularly expedient if each EndRotationsposition a sleeve member side locking element is assigned, which in turn cooperates with a respective counter-locking element, preferably the frame, in particular in the aforementioned manner for the realization of the haptic feedback.
As mentioned above, it is basically possible to form the injection chamber as an injection chamber closed in the end position of the first injection chamber part, i. an injection chamber which completely encloses the beverage substrate capsule and in which the injection chamber components are sealed against each other in the end position. However, an embodiment of the beverage preparation device is particularly preferred, in which the injection chamber is designed as an "open" injection chamber in the closed state, in which the first and second injection chamber parts, preferably via at least one seal along the adjustment axis, are supported on the beverage substrate capsule the injection chamber components spaced along the adjustment axis. In other words, in such an embodiment, the beverage substrate capsule is clampingly received between the preferably spaced injection chamber components and the beverage substrate capsule thus forms part of the injection chamber. Preferably, the beverage substrate capsule is here correspondingly stiff and has a corresponding wall thickness.
It has been found to be particularly advantageous when the water supply means are connected to the second injection chamber part, i. in that water is injected into the closed injection chamber from the second injection chamber part and / or that the first injection chamber component has an adjustable outlet for the finished beverage, which preferably, as explained above, transfers the beverage in the radial direction through the actuating means, in particular a sleeve element , derives.
The invention also relates to a method for operating a beverage preparation device designed according to the concept of the invention, wherein first a beverage substrate capsule is inserted into the beverage capsule receptacle of the first injection chamber component in the first injection chamber component located in the loading position, whereupon the first injection chamber part, in particular by displacement or axial force Actuating from the loading position along the adjustment axis in the intermediate position, preferably purely translationally adjusted, whereupon (after reaching the intermediate position), the injection chamber is closed, by rotating the actuating means to a preferably coincident with the adjustment, ie from this axis of rotation formed, wherein the rotational movement of the actuating means in a translational displacement of the Injektkkammerteils together with its beverage capsule receptacle and the actuating means takes place in the end position and also the injection chamber is locked, i. is secured against opening by pure Axialkraftbeaufschlagung along the adjustment. For unlocking a renewed or further rotation of the actuating means, preferably in the original position is necessary.
It is particularly useful if, by rotating the actuating means and the resulting translational adjustment of the first injection chamber along the adjustment axis in the direction of the second injection chamber part arranged in the beverage receptacle capsule along the adjustment axis between the first and the second injection chamber part is clamped and pressed appropriate seals become. The reaching of the locking position is preferably signaled acoustically and / or haptically, in particular by interaction of the actuating means with haptic means, in particular locking or spring means, which are preferably arranged on a frame as described above, which holds the first injection chamber part.
Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings.
These show in:

The second injection chamber part 7 are associated with water supply means not shown in detail, with which cold or not shown heating means heated water via a supply line 10 can be supplied and this way with closed injection chamber 4 starting from the second injection chamber part 7 into the beverage substrate capsule 3 can be injected.
The first injection chamber part 7 is an outlet 11 assigned, via which the finished beverage can be discharged into a beverage container.
For injecting water on the one hand and discharging water on the other hand into or out of the beverage substrate capsule 5 to enable is the beverage substrate capsule 5 on both end faces (not shown), via integral opening means of the beverage preparation device 1 ,
The first injection chamber part 6 is here exemplified by a screw 12 fixed to a frame 13 that together with the first injection chamber part 6 and the beverage capsule pickup 5 is translationally adjustable.
In the frame 13 engages from radially outside to radially inside a sleeve element 14 from to locking and advancing means 33 belonging actuating means 15 a, and about radial processes 16 , which in an outwardly open circumferential groove 17 of the frame 13 protrude. In this way, from the sleeve member 14 Compressive and tensile forces along the adjustment axis V in the frame 13 and thus into the first injection chamber part 6 be introduced.

During the adjustment movement from the loading position to the intermediate position prevent axial processes 23 the abutment element 18 a rotation of the interaction element 18 and thus the sleeve element 14 or the entire actuating means 15 in the circumferential direction, by the axial processes 23 in the circumferential direction on the inner circumference 24 a passage opening 25 in the abutment 21 support.
Overall, it can be seen that the actuating means 15 , here the sleeve element 14 the abutment 21 engages on its outer circumference in the axial direction, of one of the second injection chamber part 7 opposite outside 26 to a second injection chamber part 7 facing inside 27 or even in the direction of the adjustment axis V Furthermore. In addition, the actuating means reach through 15 the abutment 21 in an inner area through an interaction of sleeve element 14 and rotatably fixed interaction element 18 , More specifically, a support surface having a support portion.
It can be seen that in the plane of the drawing on the right, the sleeve element 14 adjacent to the bottom of the tube 20 through a decorative panel 28 is closed.
In 4 is a stationary guide frame 29 to recognize, on which the second injection chamber part 7 is formed and the two parallel guide arms 30 . 31 Includes, extending along the adjustment axis V extend. The guide arms 30 . 31 are spaced from the second injection chamber part 7 perpendicular to the adjustment axis V or connected to each other via the abutment 21 which the aforementioned passage opening 25 having. At this abutment 21 , more precisely in 5 shown inclined surfaces 32 . 33 the actuating means are based 15 via corresponding, preferably also designed as inclined surfaces support surfaces 34 . 35 the support portion of the interaction element 18 from.
6 shows a mounted state. It can be seen that the guide arms 30 . 31 in the frame 13 are arranged and lead this on its inner circumference. To recognize further is the abutment 21 which is interspersed by the actuating means 15 , specifically the interaction element 18 , In the relative position of abutment shown 21 and interaction element 18 is only a translational Relativverstellbewegung between the actuating means 15 and the fixed abutment 21 possible, since a rotational movement by concerns of Axialfortsätze 23 in the circumferential direction on the inner circumference of the passage opening 25 be prevented. This anti-rotation device is designed so that a rotation of the actuating means 15 is prevented on the entire displacement from the loading position to the intermediate position, and that only in the intermediate position, the actuating means 15 , specifically the interaction element 18 as far as axially along the adjustment axis V through the abutment 21 are shifted that the Axialfortsätze 23 no longer block the rotational movement and the actuating means 15 via preferably at least partially inclined support surfaces 34 , 35 at the corresponding inclined surfaces 32 . 33 of the abutment 21 , on its inside 27 can support.
3 shows the sleeve member 14 the actuating means 15 in his position on the frame 13 , It can be seen in a lateral surface 36 a here circumferentially closed and extending in the circumferential direction, substantially slit-shaped opening 37 extending radially outward from an end portion of the outlet 11 interspersed, as well as out 1 results.
In 2 a sectional view is shown, in which the first injection chamber part 6 is in a loading position. The frame 13 is on its outer circumference at the guide arms 30 . 31 guided. The stationary second injection chamber part 7 is on the guide frame 29 arranged, which has a connecting section 38 has, which integrally connects the guide arms together. It is the combination of connecting section 38 and leadership arms 30 . 31 to a plastic injection molded part, wherein the abutment 21 clamped and positively connected in a region of the free ends of the guide arms 30 . 31 is fixed. It can be clearly seen that in the loading position the axial extensions 23 of the interaction element 18 axially into the access opening 25 of the abutment 21 engage and thus a rotational movement of the sleeve member 14 the actuating means 15 is prevented. It can also be seen that the spout 11 initially along the adjustment axis V axially in the direction of the sleeve element 14 led away from the second injection chamber part 7 and then deflected radially outwardly through the shell-side opening 37 in the sleeve element 14 ,
Instead of the bayonet-like interaction of the actuating means with the abutment, as explained with reference to the preceding figures, it is also conceivable that the abutment and the actuating means, as explained in the general description part, cooperate in the manner of a threaded connection, ie that a first Threaded element of the actuating means engages in a counter-threaded element of the abutment. Even with such an embodiment, it is possible to prevent a rotational movement of the actuating means on the way from the loading position to the intermediate position and to allow a rotational movement with simultaneous interaction of thread and mating thread first from reaching the intermediate position - this requires the actuating means during the aforementioned first Movement phase only blocking cooperate with a stationary component, such as the abutment, such that this interaction is prevented from reaching the intermediate position - this, the actuating means may cooperate with an axial attachment with an opening in the abutment or in the frame, wherein the extension upon reaching the intermediate position is free and rotatable together with the actuating means.
In the following, the operation of the arrangement described above according to the 1 to 6 based on the highly schematized 7 to 15 explained, with regard to a preferred concrete structure to those explained above 1 to 6 is referenced with associated figure description.
In 7 is the beverage preparation device 1 partial with fully opened injection unit 2 shown. One can see in a loading position along the adjustment axis V arranged first injection chamber part 6 , which firmly connected to this and integrally formed with this beverage capsule recording 5 (see previous figures) is not shown for reasons of clarity. Since the first injection chamber part 6 located in the loading position, are the actuating means 15 maxial in the plane of the drawing to the right of the second, fixed injection chamber part 7 spaced, which on the guide frame 29 with his leadership arms 30 . 31 is arranged. Evident is also the sleeve member 14 the actuating means 15 of locking and advancing means 22 , In the loading position shown can be a beverage capsule recording 5 of the first injection chamber part 6 with beverage substrate capsule 3 be loaded. one
After the in 7 Shown the beverage substrate capsule shown 3 becomes the first injection chamber part 6 along with the beverage capsule intake 5 and the beverage substrate capsule resting thereon 3 along the adjustment axis V in the direction of the second injection chamber part 7 adjusted, by an Axialkraftbeaufschlagung on the actuating means 15 along the adjustment axis V , As a result, the actuating means 15 Concretely, comprising the sleeve element 14 and the interaction element fixed thereto 18 along with the first injection chamber part 6 adjusted axially purely translationally, relative to the abutment 21 between the guide arms 30 . 31 , While the adjustment is how out 7 results in a rotation of the actuating means 15 around here with the adjustment axis V collapsed axis of rotation prevented, due to the abutment interaction of the axial processes 23 with the inner circumference of the passage opening 25 in the abutment 21 ,
In 8th is the beverage substrate capsule 3 , more precisely, the first injection chamber part 6 with the beverage capsule holder in an intermediate position. In this intermediate position are the actuating means 15 , specifically the interaction element 18 so far axially relative to the abutment 21 adjusted that the blocking of the rotational movement is canceled and the actuating means 15 in the circumferential direction about the axis of rotation R respectively. V can be rotated.
In 9 is again shown for clarity, the device fragmentary, in an intermediate region during the adjustment of the in 7 shown loading position in the in 8th shown intermediate position. Here is clearly the impact interaction of the interaction element 18 more precisely from its axial processes 23 with the inner circumference of the through hole 25 of the abutment 21 to recognize.
In the in 8th indicated intermediate position so are the actuating means 15 free for the indicated rotational movement about the axis of rotation R , This support surfaces are based 34 . 35 the actuating means 15 , specifically the interaction element 18 at corresponding Gegenabstützflächen, which are preferably formed here as inclined surfaces 32, 33 and thereby cause an axial feed along the adjustment axis V , In other words, therefore, the rotational movement of the sleeve member 14 the actuating means 15 converted into a purely translational adjusting movement of the first injection chamber part 6 from the intermediate position to an end position.
11 shows the beginning of this rotational movement, while in 12 and 13 the end point of the rotational movement is shown. Here is the injection chamber part 6 (in the 12 and 13 not shown) together with the actuating means 15 so far along the adjustment axis V adjusted that the first injection chamber part 6 is in the final position, like this one in 14 is shown. In 14 is also the power F displayed with the first injection chamber part 6 the beverage substrate capsule 3 against the second Injection chamber part 7 subjected to force due to the axial tension by rotation of the actuating element 15 and corresponding inclined surface interaction between actuating means 15 and abutments 21 ,
In the final position, the injection process can now take place.
After completion of the injection, the actuating means 15 rotated back in the circumferential direction about the adjustment axis V to the in 11 shown relative position with respect to the abutment 21 whereby the injection chamber is unlocked. This makes it possible, as in 15 shown by Zugkraftbeaufschlagung the actuating means 15 this together with the first injection chamber part 6 back to the loading position. The beverage substrate capsule 3 is not shown by retaining means in the region of the second injection chamber part 7 retained and can after herausverfahren the beverage capsule recording 5 from an area below the beverage substrate capsule 3 fall down, that the situation is according to 16 results.
The first injection chamber part 6 is now ready to receive another beverage substrate capsule 3 ,
The following is based on the 17 and 18 the functioning of preferably provided Haptikrückkopplungsmitteln 39 explained that in the embodiment shown reaching the in the 1 and 13 shown endpoints of the rotational movement of the actuating means 15 , more precisely the sleeve element 14 feedback, by an axial feedback movement of the sleeve member 14 along the adjustment axis V ,
It is particularly preferred if, as here, the haptic feedback means 39 in addition to the rotational movement of the actuating means 15 limiting stops are provided, that is so by the haptic feedback means 39 the user gets notified early, ie shortly before reaching the stop position by haptic feedback that the force required to implement the rotational movement of the actuating means can be reduced.
The haptic feedback means 39 include for this purpose on the inner circumference of the sleeve member 14 provided, here hook-shaped locking elements 40 (of which in 17 only one is shown), wherein each locking element 40 is a counter-locking element 41 at the frame 14 is assigned, on a frame front side 42 which is directed away from the brewing chamber.
By turning the sleeve element 14 come the locking elements 40 in contact with the respective one run-on slope 42 having counter-locking elements 41 and rest after passing this slope in corresponding recesses of the locking elements 40 a - resulting in a haptic axial feedback movement of the sleeve member 14 that is felt or registered directly by the user.
