Description

The invention relates to a beverage preparation machine with a capsule-receiving device for inserting a packaged Brühgut portion, comprising a holding device comprising at least one support element and at least one holding element as sub-elements. In this case, the holding element forms a recess into which the Brühgut portion can be inserted. The support element supports the holding element and / or the Brühgut portion in the vertical direction. The sub-elements are movable in relation to each other between a loading position and an ejection position at a disposal opening.

Hot beverage preparation machines and here in particular coffee machines today often prepare drinks using brewed portions. The Brühgut portions can be on the one hand so-called coffee or tea pads and on the other hand beverage capsules. Coffee or tea pods contain ground coffee or a tea mixture within a water-permeable bag, the pad. Capsules are plastic or metal containers, optionally covered on one side by a metal foil, in which beverage concentrates or leachable solids for the preparation of a drink are kept. The capsule is pierced and water, such as hot water or steam, is passed through. As a result, the concentrate is diluted or the solid dissolved or released components of the solid into the water. The exiting from the capsule mixture is passed into a vessel where it is present after completion of the brewing process as a prepared drink.

An advantage of beverage preparation machines that process brewed portions is their ease of use. The introduction and disposal of Brühguts are much easier than coffee filter devices. A Brühgut portion can be inserted into the beverage preparation machine and then removed again as a unit. In more advanced beverage preparation machines, the brewing portions are stored in a collecting container after the preparation of a beverage, so that a user does not need to remove and dispose of the used portions after each brewing process, but much less frequently can make a collective disposal.

Such a solution shows, for example, the EP 1095605 B1 , Here is a part of the brewing chamber of a beverage preparation machine designed as a pivotable by 180 ° capsule container in which a beverage capsule is inserted from above. After the beverage has been prepared, the capsule container is thrown around an axis of rotation about 180 ° in the direction of a disposal opening in the interior of the beverage preparation machine, so that the capsule passes into the disposal opening due to the force of gravity and the momentum of the rotary movement.

Next is from the DE 60 2004 005 536 T2 a generic beverage preparation machine with an ejector arrangement for beverage cartridges and a cubic capsule holder known. In this case, the capsule holder can be moved by means of a carriage arrangement in a loading position.

The US 2003/0 071 056 A1 discloses a cubic capsule holder which moves horizontally for ejecting the beverage capsule by means of a fork-like Auswerfelements and pivoted against the direction of travel.

The object of the invention is to provide a beverage preparation machine of the aforementioned type with an alternative construction of a capsule-receiving device. The beverage preparation machine as compact as possible and / or the carriage of Brühgut portion should be designed as simple and secure in the disposal opening.

This object is achieved by a beverage preparation machine according to claim 1: A beverage preparation machine of the type mentioned is inventively further developed in that the holding element has a substantially flat plate and / or frame-shaped geometry with an extension plane for framing the inserted Brühgut portion in the horizontal direction and the capsule-receiving device is formed overall so that the movement of the sub-elements from the loading position to the ejection position relative to each other by sliding and / or tilting by less than 90 ° the Brühgut-portion along the plane of extension in a sliding movement in the direction of the disposal opening added.

The invention therefore turns away from catapulting parts of the capsule-receiving device and with her an empty Brühgutportion in a rotational movement about a catapult axis by more than 90 °. Rather, it pursues the principle of conveying the brewing portion in a kind of sliding movement slower and therefore more controlled from the loading position to the ejection position. For this purpose, a recording device is used, which consists of several sub-elements. The support member supports as one of the sub-elements of the receiving device, the Brühgut portion in the vertical direction. The holding element holds the inserted Brühgut portion during the brewing process at least partially in the lateral direction, preferably in the horizontal direction of space. For this purpose, the holding element comprises at least one recess into which the Brühgut portion can be inserted, so that it is at least partially in positive connection with the support element and is thereby supported by the support element. The depression may comprise the broth portion completely or partially, so be open in one or more directions. The decisive factor is a framing of the Brühgutportion by the holding element in a kind of "footprint"("footprint"), which images the outline of the Brühgut portion in its support plane on the support element. This results in not only a holding effect, but also the advantage that a user, especially when choosing a non-circular outline of Brühgutportion, can be guided to where and how exactly he should position the Brühgut portion when inserting.

In the areas where the depression does not comprise the brewing portion, other elements of the beverage preparation machine can fix the brewing portion so that it is held laterally firmly in the insertion position Such a fixation can be about piercing devices, sealing rings of a brewing head or protruding parts of the support element done.

The beverage preparation machine knows an insertion, a lay-up and an ejection position. The insertion position of the capsule-receiving device is the position in which a Brühgut portion can be inserted by a user and is held by the sub-elements of the capsule-receiving device in position. The loading position therefore corresponds to a laying position of the brewing head of the beverage preparation machine. The Auflegeposition is that position in which the brewing head is placed on the Brühgut-portion and forms a brewing chamber together with the capsule-receiving device. The Brühgut portion is preferably aligned horizontally along at least one of its flat sides and arranged in an area in which the brewing head can fit accurately on her. Together with a subdivision, which may for example be wholly or partly formed by the support member, the brewing head forms the brewing chamber.

In the ejection position, the brewing portion is arranged so that its position corresponds to that of the disposal opening. Preferably, it is located vertically or obliquely above the disposal opening, so that it can fall into the disposal opening due to gravity. For this purpose, the Brühgut portion can be transported in the direction of the disposal opening and / or the disposal opening to be moved in the direction of Brühgut portion.

The sliding of the Brühgut portion in the direction of the disposal opening can be done according to two different principles: The Brühgut-portion can be placed alone in a sliding movement or at least one of the two sub-elements of the capsule-receiving device slides along with the Brühgut-portion along the other sub-element latter means that the two sub-elements are moved relative to each other. Both sliding principles can also be combined with each other. This results in a quieter movement, for which less space is required as in the cited prior art and for the principle also only a partial opening of the brewing chamber after the brewing process is necessary. It can be prevented, for example, that hot vapors come out of the brewing chamber after the brewing process outwardly and thus endanger users. In fact, a sliding movement can already take place when the brewing chamber is partially or almost completely closed so that the still hot spent brewing portion can no longer come into contact with the user at all and hot residual vapors can be removed in a more controlled and slower way to the outside.

According to a first variant of the beverage preparation machine according to the invention, the holding element above the support element, the disposal opening are arranged in a plane defined by the extension of the support member level and offset the recess and the disposal opening in the loading position horizontally to each other and come in the ejection position substantially to cover.

The disposal opening is thus realized within the support member as a recess or arranged at one end of the support member Above the support member, the holding member is mounted, whose main extension is preferably aligned parallel to the support member It may, for example, rest on the support member or be suspended above. The exact arrangement and the height of the holding element is essentially determined by the height of the Brühgut portions used and by the internal dimensions of the brewing head, which rests on the Brühgut portions.

In the first variant, the recess of the retaining element is offset in the loading position horizontally to the disposal opening. By appropriate displacement of the holding element or the support element, for example, after pivoting along a pivot axis or by moving in a linear movement, the recess and the disposal opening come together to cover, so that the Brühgut- Portion can get out of the depression in the disposal opening. This position is the ejection position. Achieving the ejection position, in which the depression and the disposal opening essentially coincide, is thus functionally defined by the fact that the fraction of broth may fall from the depression into the disposal opening.

The two sub-elements are moved in the first variant relative to each other. This may mean that the holding element is displaced so that its recess is moved in the direction of the disposal opening, while the support element is fixed. The holding element can be designed, for example, as a slide with a depression which is displaceably arranged along a guide groove. The extension plane of the holding element thus forms a sliding plane of the Brühgut portion in the direction of the ejection position. The Brühgut portion is disposed of in a receptacle below the disposal opening.

It can also be the support member are moved so that the disposal opening is moved in the direction of the recess in the holding member while the holding member is fixed. This means that the disposal opening is part of the support element and thus is moved with the support element with. In this case, the receptacle is below the recess of the retaining element.

In addition, the movement of the support member and the holding member can be combined, so that the disposal opening and the recess of the holding member in the ejection position are both positioned at a different location than in the loading position. Below this location of the disposal opening in the ejection position then the receptacle for the spent Brühgut portions.

In a first variant, there is a certain offset between depression and disposal opening in the insertion position. As a result, the support member supports the Brühgut portion and the holding member holds it in position laterally fixed.

In a second variant of the beverage preparation machine according to the invention, the holding element above the support element, the disposal opening are arranged in a plane defined by the extension of the support member level and the recess and the disposal opening in the loading position horizontally offset from each other, while the holding element in the ejection position by pivoting from the loading position is arranged at an angle to the support element. Instead, as in the first variant, to move the holding member and the support member with respect to each other substantially along a displacement plane, in this variant, a tilting of at least one of the two sub-elements about a tilt axis, so that the holding element and the support element in the ejection position at an angle are arranged to each other. In this case, the maximum angle of the two partial elements is preferably less than 90 °, particularly preferably less than 60 °.

In the second variant, the holding element can be tilted upwards from the plane of the supporting element. The Brühgut portion is thereby lifted from the support element and thereby loses contact, for example, to piercing devices in the support element. Due to gravity, the Brühgut-portion slides from a certain angle of the support member to the support element automatically in the direction of the tilting axis and beyond in the direction of the disposal opening, which is arranged in the tilting axis (ie also something this side or beyond this axis).

It can also be the support element tilted from the plane of the support member downwards. Such tilting is particularly preferred when the Brühgut portion is pierced from above, so if, for example, the piercing device is arranged in the brewing head of the beverage preparation machine. By tilting the support member down the Brühgut-portion then loses its lateral stabilization and can be directed away from the tilt axis due to gravity down.

Thus, in the second variant, the two subelements do not slide against each other in the first place, but a sliding movement of the brewing material portion in the direction of the disposal opening is initiated. This sliding movement is effected by tilting or pivoting at least one of the two sub-elements with respect to the respective other sub-element. Preferably, the retaining element is tilted, as it is thereby at least partially spaced from the support element, so that the vertical support function of the support member is repealed and the Brühgut portion easier to slide or slide. The second variant offers, inter alia, the advantage that only a very small space requirement along the main extension plane of the two sub-elements arises. Since the sliding movement is caused by a movement of at least one of the two sub-elements up or down, a movement of the main extension plane of the capsule-receiving device defined by the two sub-elements in the insertion position is not necessary. As a result, the depth of the beverage preparation machine can be kept lower than in the first variant.

In principle, it is also possible to combine both variants. This then means that both a displacement of the two sub-elements relative to each other along a displacement plane (which is defined by the main extension plane of the two sub-elements in the insertion position) is performed as well as a pivoting movement. A combination of the two active principles can mean that the particularly well controllable holding of the brewing material portions according to the first variant is combined with the possibility of designing the beverage preparation machine with a relatively small overall depth according to the second variant.

According to the invention, in the beverage preparation machine, a movement of partial elements takes place relative to one another, which causes a sliding movement. This movement of the sub-elements can in principle cause an independent actuator, such as a motorized, a spring-based or by manual operation of a user. It is preferred that the beverage preparation machine comprises a coupling arrangement which couples in operation, the movement of at least one of the two sub-elements from the loading position to the ejection position with an opening and / or closing movement of the brewing chamber. The coupling offers several advantages for the operation of the beverage preparation machine and for increasing the user-friendliness. The opening of the brewing chamber after a brewing process is anyway the time in which the disposal of the used Brühgut portion can and should be initiated. Thus, the opening of the brewing chamber logically corresponds to a change in the function of the capsule-receiving device in the sense that the receiving device from the loading position, the ejection position can be adjusted. A coupling, preferably a mechanical one, therefore serves to translate this operational logic into a technical automatism. At the same time it is ensured that a user shortly after opening the brewing chamber finds an empty brewing chamber, in which he can immediately insert a new Brühgut portion. Operating errors are therefore largely excluded; In addition, the user comfort is increased and the risk of scalding on the still hot used Brühgut portion is counteracted.

Such a coupling can be formed both electronically or electrically as well as mechanically and also comprise combinations of mechanical and electronic / electrical coupling. For a mechanical coupling, for example, push rods or pull rods, cables, shafts, gears or gear parts or the like can be used. An electronic / electrical coupling is preferably based on an electronic control that generates control signals in response to the position of a portion of the brewing chamber, which control an electric actuator, such as an electric motor suitable to the desired movement of the sub-elements of the capsule-receiving device in the way conduct.

Particularly preferably, a coupling is used, which in operation only the opening movement of the brewing chamber with the movement of the respective sub-element in the direction of the ejection position, in particular exclusively until reaching the ejection position, coupled This means that the return movement of the respective sub-element not to a movement of the brewing chamber is coupled, but only the movement of the loading position in the ejection position. This results from the logic that it is only necessary after brewing to ensure that the spent brewing portion reaches the disposal opening. However, it is not absolutely necessary that the receiving device is immediately returned to the loading position after the ejecting operation. Such a return can be done, for example, by human intervention or on the basis of independent actuators. Such actuators can also be used, for example, at the same time to automatically carry out a refilling of the brewing chamber when reaching the loading position. The decoupling of the movement of the respective sub-element of the movement of the brewing chamber after completion of the opening movement of the brewing chamber or already on reaching the ejection position can also serve other purposes: If the ejection position of the partial element is reached, a short dwell period is required in which Ejection process, d. H. the falling into the Brühgut-portion in the disposal opening, can be performed. Therefore, particularly preferably the movement coupling of brewing chamber and sub-element already ends at this time. Even more so, it may in many cases be undesirable to couple the return of the partial element into the insertion position with the movement of the brewing chamber, since this would mean that the brewing chamber would have to be at least partially closed again for this return. Therefore, the movement coupling between the movement of the brewing chamber and the respective sub-element is limited to the time of the opening movement of the brewing chamber and preferably to the time until the ejection position is reached.

The decoupling also allows cleaning or maintenance in the interior of the beverage preparation machine while the receiving device is in the ejection position. In the ejection position, the beverage preparation machine is then preferably designed such that a user receives access to parts of the beverage preparation machine to be serviced or cleaned may be possible in the ejection position, the removal of a Brühgut-rest container, the position in the ejection position at the same time requires an unlocking of the Brühgut-residual container, which makes the removal possible. Also other unlocking mechanisms for Providing access to the interior of the beverage preparation machine are possible.

Preferably, the beverage preparation machine comprises a movement drive for the automatic, that is to say automatic, movement of at least one of the two partial elements in at least one direction of movement. The movement drive or actuator may comprise, for example, a spring-based automatism and / or a motorized motion drive. The movement drive can replace the coupling of the opening movement of the brewing chamber with the movement of at least one of the two sub-elements from the loading position to the ejection position. It can also serve to guide the respective moving part element back into the insertion position, for example if, as mentioned above, a movement coupling for movement into the ejection position is realized. It is therefore particularly preferred that the movement drive moves the sub-element in operation only from the ejection position in the insertion position. Thereby, the movement of at least one of the two sub-elements can be realized from the insertion position to the ejection position by means of a movement coupling with the opening movement of the brewing chamber, while the return is carried out in the state of the insertion position by means of the movement drive. The return can therefore also be carried out with a time delay for movement from the loading position to the ejection position.

It has proved to be particularly advantageous if the beverage preparation machine comprises a trigger of the movement drive which triggers the movement drive upon reaching a defined position of a partial element and / or another machine element that is at least partially motion-coupled to the partial element. For example, the achievement of a target position of a brewing head trigger the movement drive and thus automatically cause the return transport of the respective moving part element. The triggers may include, for example, suitable slide guides in combination with spring mechanisms. The triggering of the movement drive can also take place with a time delay to reach the defined target position of the machine element. For example, a time offset can be used to complete the ejection process of Brühgut portion. This ensures that no brewing material portions, in particular capsules, remain within the beverage preparation machine in an area in which they could lead to mechanical blockages.

According to a further advantageous embodiment of the invention, the beverage preparation machine may comprise a lifting element as part of at least one of the two sub-elements, which is designed to be vertically movable at least in the loading position of an insertion position in a brewing position. The lifting element can serve to push the Brühgut portion from below in the direction of the brewing head to form a closed brewing chamber can. At the same time, the lifting element can also serve to prevent a displacement of one of the two sub-elements during a brewing process. It can thus serve by a blocking function of the safety of the beverage preparation machine in brewing.

It is therefore particularly preferred that the lifting element in the brewing position at least partially prevents a horizontal displaceability of the sub-elements. This at least partial inhibition is that the displacement of the broth is prevented during the brewing process using the sub-elements. Optionally, it may also be provided that the force which prevents the displaceability of the sub-elements, is only so great that they can be overcome by deliberate or deliberate action of a user or an actuator, without damaging one of the sub-elements. In this way, it can be ensured that the blockage can, with the help of the lifting element, if necessary, also be selectively canceled again.

In a lifting element or within at least one of the two sub-elements is also preferably a piercing device for piercing a Brühgut-portion arranged. If the piercing device is integrated, for example, in the lifting element, the lifting of the lifting element in the direction of the brewing head of the brewing chamber can simultaneously serve to pierce the brewing portion. Thus, the brewing process can be started automatically upon reaching the brewing position of the lifting element.

The principle of the invention will be explained in more detail below with reference to a drawing by way of example. In the drawing show:

1 and 2 show a part of a beverage preparation machine 1 according to a first embodiment of the invention in a side view ( 1 ) and in a perspective view obliquely above. Shown here are essentially the brewing chamber 18 and the surrounding machine elements in a presentation to the insertion position. The brewing chamber 18 on the one hand by a brewing head 19 on a lever arm 17 formed, which is arranged pivotably about a first axis A ₁ . A second axis A ₂ , whose function is explained in more detail in the following figures, runs parallel to the first axis A ₁ . For easier pivoting and locking of the brewing head 19 in a brewing position of the brewing chamber 18 (see. 5 ) serves a semicircular handle 21 on the top of the brewing head 19 , Two side-mounted notches 23 serve to lock the brewing head 19 in the brewing position.

The counterpart of the brewing head 19 forms a capsule cradle 3 , which is composed of several interacting elements: In a support element 5 is a lifting element 30 let in, which is movable up and down within a margin. At its top, the lifting element 30 a piercing device 45 on. It serves to pierce a beverage capsule as Brühgut portion (see. 3 et seq.). At the bottom of the lifting element 30 is a spout 31 appropriate. At the top of the support element 5 can be a support frame 7 be placed here, the sake of clarity of the support element 5 is lifted off obliquely. He is using a nose 11 in a top-side notch 9 of the support element 5 Can be fixed at its one end in the longitudinal direction and at the other end by means of a downwardly projecting tooth 13 in a recess of the support element 5 insertable. This allows the holder frame 7 on the support element 5 be held. For fixing the holding frame 7 on the tooth 13 serves a spring-driven latch button 15 in the support element 5 which is in a depression of the tooth 13 is insertable.

Inside the support frame 7 is a holding element 27 arranged along an inner longitudinal rail 29 of the holding frame 7 is slidable. The holding element 27 points in the area that coincides with the position of the lifting element 30 corresponds, a recess 25 in the form of an opening 25 on whose inner contour is equal to the outer contour of a einzulegenden beverage capsule. The support element 5 has parallel to its longitudinal course a guide trough 8th in which a guide pin 10 is inserted, which with the holding element 27 is firmly connected. On the other, not recognizable here longitudinal side of the support element 5 are just such a guide channel 8th and a similar guide pin 10 appropriate. By moving the guide pins 10 from the bottom of the support element 5 along the guide trough 8th can therefore the retaining element 27 parallel to the main extension plane of the support element 5 be moved.

3 and 4 show the same beverage preparation machine 1 in a partial sectional view ( 3 ) and in a sectional view along a section line AA ( 4 ). The beverage preparation machine 1 is here in the insertion position, which here also the Auflegeposition for the brewing head 19 is. The brewing head 19 is almost closed and a beverage capsule 37 is in the brewing chamber 18 inserted. The rest 23 are in the case of the supporting member 5 already locked. In this loading position is the holding frame 7 together with the retaining element 27 on the support element 5 on, leaving the holding frame 7 and the support element 5 are arranged substantially parallel to each other.

The support plate 5 has a disposal opening in its center 39 in the form of a recess extending from the lifting element 30 in the direction of the first axis A ₁ downwardly opens obliquely. Through the disposal opening 39 through the Brühgut capsule 37 after a completed brewing process in a lower area (not shown) of the beverage preparation machine 1 be dumped where it is collected in a collection and later disposed of.

In the left area of the 3 is also recognizable that at the end of the lever arm 17 a quarter-circle gear 33 is formed, that over another gear 32 a guide wheel 34 (in detail in 4 recognizable) moves. The guide wheel 34 rotates about the second axis A ₂ . It is also in a frame 36 the beverage preparation machine 1 a backdrop 35 whose function will be explained in more detail below.

The scenery 35 and the guide wheel 34 are part of a coupling arrangement 2 , This also includes a push rod 41 in the housing of the support element 5 is admitted. The push rod 41 is at her the lifting element 30 opposite end with a rounded reinforcement 43 equipped and formed of flexible material. In the area of their lifting element 30 facing the end, she is firmly with the guide pin 10 (see. 1 and 2 ), so that they reciprocate the holding element 27 can cause. By a spring (not shown) it is held in the position shown here or returned to this position when it is deflected from it. A deflection is through the gears 32 . 33 driven guide wheel 34 , that makes it possible at his in the 4 lower edge of his quarter circle one towards the backdrop 35 pointing nose 58 having. The guide of the push rod 41 in the field of reinforcement 43 takes over the scenery 35 , The scenery 35 also has one of the shape of the guide wheel 34 in about corresponding quadrant shape. In its lower starting area it forms a hollow 36 ; At the other end, it is led away a little from the course of the quarter circle to the outside. As in the 5 . 7 and 9 The nose is still recognizable 58 of the guide wheel 34 at the reinforcement 43 attack and this along the scenery 35 move to the point where the course of the backdrop 35 from the guide wheel 34 leads away.

In the loading position is the Brühgut capsule 37 into the depression 25 inserted, the depression 25 just above the lifting element 30 is positioned. The brewing head 19 can so directly on the Brühgut capsule 37 rest. By further pressing the brewing head 19 down and by lifting the lifting element 30 becomes the brewing chamber 18 the beverage preparation machine 1 closed. At the same time, using the piercing device 45 the brewing capsule 37 pierced, and hot water can through the Brühgut capsule 37 be passed through, so that over the outlet plug 31 a hot drink can be obtained.

5 shows the beverage preparation machine 1 in the same sectional view as in 4 in a third position, namely the brewing position. The brewing chamber 18 is closed and thus the guide wheel 34 in an extreme position in which the nose 58 at the rear (the capsule holder 3 facing) end of the reinforcement 43 attacks. This allows the guide wheel 34 with the nose 58 with a clockwise turn the gain 43 and thus the push rod 41 can move. To the reinforcement 43 to cover up like that, had to nose 58 at the reinforcement 43 slip past (cf. 4 where the nose 58 still on the other side of the reinforcement 43 was positioned). This is made possible by the push rod 41 sufficiently flexible, so that the reinforcement 43 through the nose 58 into the hollow 36 be pressed and the nose 58 so that can dodge, leaving the nose 58 about the reinforcement 43 can slip past or past.

6 and 7 show the beverage preparation machine 1 in a fourth position, namely during the opening of the brewing chamber 18 after a brewing process. It can be seen that the retaining element 27 during opening of the brewing chamber 18 in the direction of the first axis A ₁ by the movement of the tooth 10 (due to the movement of the coupling device 2 ) is moved. This slides the Brühgut capsule 37 automatically with in the direction of the position of the bottom disposal opening 39 (see. 5 ).

The interaction between the opening movement of the brewing chamber 18 ie raising the brewing head 19 , and the sliding movement of the holding element 27 together with the used Brühgut capsule 37 is based on the sectional view in 7 more clear. The pivoting of the lever arm 17 move that with the lever arm 17 directly connected first gear 33 and indirectly with the first gear 33 connected second gear 32 (see. 3 ). The second gear 32 that directly with the guide wheel 34 connected, the guide wheel rotates 34 , This will take the guide wheel 34 with the nose 58 the reinforcement 43 the push rod 41 along the scenery 35 With. The push rod 43 in turn moved over the guide pin 10 (see eg. 1 ) the retaining element 27 and pull it towards the disposal opening 39 ,

8th and 9 show the beverage preparation machine 1 in a fifth position, namely in the ejection position of the capsule-receiving device 3 , The holding element 27 has now arrived at a position where the indentation 25 diagonally above the disposal opening 39 lies so that the brewing capsule 37 through the disposal opening 39 can fall down.

In the ejection position according to 9 is the reinforcement 43 the push rod 41 in the upper end of the scenery 35 arrived, which spreads easily at this end of the arc of the quarter circle. If the reinforcement comes there, it can be there easily from the side of the guide wheel 34 push away, leaving the nose 58 of the guide wheel 34 the leadership of the reinforcement 43 will lose in the next moment. As a result, the spring force of the push rod 41 attached spring act and the push rod 41 return to the position they are in 4 would have. This is at the same time an automatic return of the retaining element 27 into the insertion position, because the movement of the substance 41 gets over the tooth 10 (see. 1 ) directly on the holding element 27 transfer. A new brewing capsule 37 can into the capsule cradle 3 be inserted.

10 to 12 show a beverage preparation machine 1' according to a second embodiment of the invention in a perspective side view ( 10 ), a perspective view from the bottom ( 11 ) and in a sectional view along a section line BB. The beverage preparation machine 1' is here in the insertion position with closed brewing chamber 18 ' shown, that is a brewing head 19 , which is designed substantially in analogy to the one shown above, closes the brewing chamber 18 ' the beverage preparation machine 1' Completely. A capsule cradle 3 ' the beverage preparation machine 1' includes a support element 5 , which is also formed substantially analogously to the previously described, and a holding element 7 ' , The holding element 7 ' lies in the position shown the beverage preparation machine 1' on the support element 5 and is therefore substantially parallel to the main plane of insertion of the support element 5 aligned.

The holding element 7 ' has a front side (in the illustration in 10 left), which at the same time the front of the beverage preparation machine 1' is. On its side opposite the front side of the holding element runs 7 ' in a leadership area 55 downwards along the boundary of the support element 5 past this down into an adapter 51 into it. The adapter 51 is pivotally mounted along an adapter axis A ₃ and is on its underside by a spring 53 pushed up. This is partially formed as a coil spring, partially as a kind of leaf spring. The feather 53 is also with a push rod 49 connected to her the adapter 51 opposite end region is equipped with teeth on the upper side. These teeth engage in a gear 47 one with the brewing head 19 connected is. Will the brewing chamber 18 ' opened, ie the brewing head 19 lifted, it pivots about a first axis A ₁ , thereby moving the gear 47 and thus indirectly the push rod 49 , The push rod 49 is moved towards the front. The adapter 51 , the push rod 49 and the gear 47 together form a coupling arrangement 2 ' , the movement coupling the movement of the brewing chamber with a movement of the holding element 7 ' serves.

Analogous to the first embodiment of the beverage preparation machine 1 according to the 1 to 9 is also in the second embodiment shown here an outlet plug 31 on the underside of the support element 5 appropriate. Likewise, the support element 5 a disposal opening 39 in, in the position shown here, a partial area 57 of the holding element 7 ' protrudes.

In 11 It can be seen that the areas of the beverage preparation machine shown here 1' are formed axially symmetrical, which means that the mentioned on one longitudinal side of the beverage preparation machine 1' attached elements are held on the other long side gegengleich same again once. This measure increases the smoothness and thus the ease of use of the capsule-receiving device 3 ' , In addition, the reliability of the machine is increased, as this also diagonal forces are compensated, the opening and closing of the brewing chamber 18 ' could lead to entanglements or jamming.

13 shows in detail in perspective view parts of the coupling arrangement 2 ' namely the push rod 49 and the adapter 51 , The adapter 51 is as upwardly open hollow body with an inlet recess 61 educated. Into the inlet recess 61 is in the installed state of the adapter 51 the management area 55 of the holding element 7 ' admitted (cf. 10 ). With the help of a screw 59 , which is aligned in the axial direction of the adapter axis A ₃ , it is on the support element 5 (not shown here) pivotally fixed. Lower side in its longitudinal direction, ie the longitudinal direction of the push rod 49 , points the adapter 51 a depression 64 on (with this depression 64 in the lower area in the 13 is not recognizable - cf. For this 15 ). The depression 64 sits down at the of the screw 59 further away front side of the adapter 51 between two obliquely upwards larger expectant noses 66 continued. In this depression 64 becomes a wire of the spring 53 held (not shown here - see eg. 10 ). At its the push rod 49 facing flank side in the lower area, the adapter 51 a guide pin 63 on, in a laterally set backdrop 65 the push rod 49 intervenes.

Through the slide tour 65 the push rod 49 can the adapter 51 in a reciprocating movement in an opening direction M ₁ and in a closing direction M _{2 of} the push rod 49 be forced into an up and down movement. The scenery 65 consists of a substantially V-shaped recess in the middle of a wedge-shaped projection 69 protrudes. Above the wedge-shaped projection 69 connects a partial recess the two outer ends of the legs of the V-shape of the backdrop 65 , This partial recess is through a spring area 67 in the push rod 49 The material of the push rod 49 in this pen area 67 Strengthens towards the teeth, leaving the spring area 67 at its end facing away from the teeth in about as far from the plane of the backdrop 65 protrudes like the wedge-shaped projection 69 , The spring action of the spring area 67 is characterized by a substantially L-shaped material recess 68 reached. The material recess 68 comprises a first leg pointing obliquely upwards and one in the longitudinal direction of the push rod 49 extending second leg.

Will the push rod 49 moved in the opening direction M ₁ , so the forced operation causes the backdrop 65 together with the bottom of the adapter 51 acting spring 53 (see. 1 ) that the guide pin 63 a substantially V-shaped forward movement K ₁ obliquely down along the wedge-shaped projection 69 and afterwards (due to the spring force of the spring 53 and the forced operation) runs obliquely upwards. This results in a kind of pitch movement of the adapter 51 , in which the adapter is tilted downwards by about 30 ° and then back into the in the 13 retracted position shown. Will the push rod 49 then moved back in the closing direction M ₂ in the starting position shown here, it changes to the orientation of the adapter 51 nothing, because the guide pin 63 is in this closing movement M ₂ in a return K ₂ linear over the spring range 67 guided. While the guide pin 63 the spring area 67 happens, this is easily removed from the adapter 51 pressed; after passing the spring area snaps 67 back to the position shown in the figure. The feather area 67 in this position prevented at the next movement of the push rod 49 in the opening direction M ₁ that the guide pin 63 can be moved linearly so that the guide pin 63 again his V-shaped forward movement K ₁ goes through.

The effect of the coupling arrangement 2 ' caused movement on the positions of the beverage preparation machine 1' is based on the 14 and 15 comprehensibly. In 14 is the beverage preparation machine 1' shown in a second position, namely during the opening of the brewing head 19 , ie pivoting along its axis A ₁ . Also in this position is the capsule-holding device 3 ' still in insertion position. By the movement of the gear 47 becomes the push rod 49 moved in the opening direction M ₁ .

In 15 is the final state of this opening movement of the brewing head 19 to see, where the beverage preparation machine 1' or the capsule holding device 3 ' in the ejection position. Due to the movement of the push rod 49 and the scenery tour 65 became the adapter 51 tilted. This is also the retaining element 7 ' at the same angle to the in 14 orientation shown tilted as the adapter 51 holding the retaining element 7 ' over the leadership area 55 holds. By tilting the retaining element 7 ' is the brewing capsule 37 from the support element 5 have been separated and in a slanted position, by which they are due to gravity in a sliding movement obliquely downwards towards the disposal opening 39 is offset. The brewing capsule 37 Slips or slides slowly out of the capsule-receiving device 3 ' out and is disposed of in a collection container.

Since the preceding beverage preparation machines described in detail are exemplary embodiments, they can be modified in a customary manner by a person skilled in the art to a large extent without departing from the scope of the invention. In particular, the specific embodiments of the capsule-receiving device can follow in a different form than described here. For example, the recess in the retaining element does not necessarily have to be designed as an opening. Likewise, the support element can serve purely for supporting the retaining element and not in addition to supporting the respective Brühgut portion. Likewise, the coupling arrangement can be configured in a different form, if this is necessary, for example, for reasons of space or designerischen reasons. Furthermore, the use of the indefinite article "on" or "one" does not exclude that the characteristics in question may also be present multiple times.
