• the opposite case is also conceivable, i.e. at least one axis penetrates the actuator element 14 at least partially (for example, two axes that engage in the actuator element on both sides can also be provided) and the actuator element 14 can optionally be pivoted about the tilting axis A, with the axle is arranged in a rotationally fixed manner, or the axle that is formed separately from the actuator element 14 is rotationally fixedly connected to the actuator element 14 and rotates relative to the main unit 2.
• FIG. 5 shows the situation in which a user has inserted a cartridge system in the cartridge holder 3, but the locking means 13 has not yet been moved to the locked position.
• the representation is very similar to that in Figure 2 was selected, so that reference is made to the relevant explanations, in particular with regard to the other components.
• the recess of the cartridge holder 3 is designed to taper conically downwards. In this way, the cartridge system can only be inserted into the cartridge holder 3 from above and is held in the cartridge holder 3 in a form-fitting manner, so in particular it cannot fall down out of the cartridge holder 3 .
• the inner contours of the recess of the cartridge holder 3 and the outer contours of the cartridge receptacle 11 are preferably of complementary design, so that a positive fit is facilitated.
• the cartridge receptacle 11 and the recess of the cartridge holder 3 deviate from a perfectly circular cross section, with a flattening preferably being present in particular in the area of the fluid supply or the coupling element. In this way, on the one hand, the particularly fluid-tight coupling of the coupling element 16 to the cartridge holder is simplified, on the other hand, it is ensured in a particularly advantageous manner that the cartridge system is correctly inserted into the cartridge holder 3, thereby avoiding operating errors.
• the piercing pin 17 of the cartridge discharge device is still in the retracted position, the sealing foil 10 is still undamaged.
• the locked position is now shown in FIG.
• the user has turned the operating element 6 and therefore indirectly transferred the at least one locking means 13 into the locked position, in which the locking means 13 engages behind the flange 9 of the cartridge 7 .
• the cartridge system can now no longer be removed from the cartridge holder 3, an accidental outflow of liquid from the beverage preparation machine 1 without a cartridge holder 11 is prevented in this way.
• the control device preferably releases the start of beverage preparation via a further control element 6'.
• the beverage preparation can also start automatically.
• the optional identifier detector 18 can, for example, detect the insertion of a suitable cartridge system and/or receive preparation parameters and forward them to the control device.
• Preparation parameters are, for example, a liquid volume, a liquid temperature, a degree of carbonization, a speed of the liquid flow, a compressed air volume and/or a speed of the compressed air flow.
• the coupling element 16 has been brought up to the fluid supply of the cartridge holder 11 in a manner not explained in detail here, so that a fluid-tight connection of the compressed air line on the cartridge holder side with the compressed air line of the coupling element 16 and a fluid-tight connection of the fluid supply on the cartridge holder side with the liquid line of the coupling element 16 is established.
• the control device can now determine the optimum point in time for transferring the beverage substance into the mixing chamber and control the drive, for example the electric motor, accordingly.
• This actuates the actuator element 14 , which in turn contacts the piercing spike 17 and moves it upwards along the spike guide, so that the tip of the piercing spike 17 pierces the sealing film 10 .
• the compressed air line integrated into the piercing spike is now aligned with the compressed air line of the cartridge holder and/or the compressed air line of the coupling element 16, so that the compressed air provided by the compressed air source can reach the reservoir and support the transfer of the beverage substance through the hole in the sealing film 10 into the mixing chamber .
• the beverage flows through the beverage outlet of the cartridge holder into the drinking vessel provided (or the liquid collection device provided in the storage area).
• FIG. 7 now shows the situation after the end of the beverage preparation.
• the piercing spike 17 is in the extended position, the locking means 13 has been transferred to the unlocked position, in particular by the user transferring the operating element 6 back to the unlocked position.
• FIG. 8 shows a schematic cross section of a cartridge holder 3 and an actuator element 14 according to an exemplary embodiment of the present invention.
• a cartridge receptacle 11 inserted into the cartridge holder 3 can also be seen, although for the sake of clarity the associated cartridge 7 has not been shown.
• the actuator element 14 is not designed here as an elongate rocker arm, but as an angled rocker arm. Has a ram at its tip, the rounded surface of which interacts preferably in a form-fitting manner with a correspondingly concave underside of the piercing spike 17 . Due to the angled shape, the direction of the force can be changed.
• the drive 12 in the main unit 2 can be positioned and/or designed differently. If, for example, a drive 12 as shown in FIG. 2 is to be used, a deflection mechanism 15 (not shown here) is required, which accordingly redirects the force provided by the drive 12 to the actuator element 14 as the output.
• a linear drive that works on thrust and is arranged horizontally in the main unit 2 in the simplest case is particularly suitable.
• FIG. 9 shows a perspective view of an actuator element 14 and a drive 12 according to a further exemplary embodiment of the present invention.
• the drive is a rotary drive, for example again an electric motor, which drives the actuator element 14 via a deflection mechanism 15, here for example a transmission gear.
• a deflection mechanism 15 for example a transmission gear.
• the drive 12 , the deflection mechanism 15 and the actuator element 14 can be arranged together at least partially on the underside of the cartridge holder 3 .
• the drive can also be arranged directly in the transition area between the cartridge holder 3 and the main unit 2 . For the sake of clarity, only the piercing spike 17 of the cartridge system is shown.
• FIG. 10 shows a perspective view of an actuator element 14 and a drive 12 according to yet another exemplary embodiment of the present invention.
• the drive 12 can be designed as a rotary drive and in particular as an electric motor.
• the drive 12 is arranged here in the main unit 2, which is only indicated in the drawing.
• the drive 12 is connected via a shaft to a deflection mechanism 15, which is designed here as a worm gear. This deflection mechanism 15 is in turn connected to the actuator element 14 .
• the drive 12 is arranged in the main unit 2, where there is generally more space available than in the cartridge holder 3, but the illustrated embodiment of the drive 12 in the main unit requires little space.
• shafts and the worm gear means that there is no translation, so that there is no need to provide free space into which elements can move.
• the arrangement shown is possible, although the drive 12 and the actuator element 14 are located on different horizontal planes. A rotation on one level about a horizontal and longitudinally arranged axis of rotation is thus diverted into a rotation about the tilting axis, which is oriented transversely to the axis of rotation and also horizontally, in a lower horizontal plane.
• FIGS. 11a and 11b show perspective views of an actuator element 14 according to a further exemplary embodiment of the present invention.
• the drive 12 can, for example, be designed identically to the drive 12 explained in connection with FIG.
• the deflection mechanism 15 comprises a lever which can be pivoted about a tilting axis A, with the drive 12 acting on the machine-side end of the lever and the other end being mounted in a longitudinally displaceable manner in a link guide of a vertically movably arranged plate-shaped element 19 of the cartridge holder 3.
• a lower, movable, plate-shaped element 19 of the cartridge holder 3 is moved upwards along the direction of movement 100 via the lever of the deflection mechanism 15 .
• the actuator element 14 is firmly attached to this plate-shaped element 19 and is therefore also moved upwards and thus activates the piercing spike 17 and transfers it from the retracted to the extended position.
• a movable element 19 on the underside of the cartridge holder 3 is firmly connected to the actuator element 14 and, in contrast to the variants discussed above, the triggering movement here is a purely vertical translation 100.
• This is advantageous compared to a pivoting of the actuator element 14 , since in this case the relative orientation of the actuator element 14 and the piercing spike 17 to one another remains unchanged.
• the person skilled in the art understands that in particular the drives 12 and deflection mechanisms 15 discussed in FIGS. 2 and 8 to 11 can also be combined with one another, so that the person skilled in the art can select the combination of deflection mechanism 15 and drive 12 that is suitable for the respective installation situation.
