Description

Technical Field

[0001] The present invention relates to a beverage preparation machine for dispensing (edible) liquids or beverages such as water, flavored water, fortified water, coffee, tea, soup, etc. by interaction, for example, between a liquid (e.g., water) and an edible product (e.g., in an injectable, powdered, gelled, pasty, or liquid form) placed in, preferably, a capsule, pad, pod, sachet, container, etc. The present invention further relates to a method for dispensing a liquid such as the above-described edible liquid or beverage (product).

Background Art

[0002] Beverage preparation machines are conventionally well-known. In these machines, a liquid is fed through the machine and dispensed at a dispensing outlet. The liquid can be adjusted (e.g., cooled or heated) before being dispensed. The liquid can interact with an edible product to prepare a specific beverage product such as coffee, tea, or soup or other liquid food. The liquid can also interact with the edible product so as to be fortified or flavored before being dispensed. The liquid may be fed through a preparation unit for interacting with the edible product. Thus, the edible product can be placed in a capsule or other type of receptacle that can be selectively arranged within the preparation unit so as to allow the liquid to enter the capsule for interacting with the edible product.

[0003] The liquid or beverage is usually dispensed into a drinking container arranged below the dispensing outlet. Thus, the drinking container is usually arranged on a cradle arranged below the dispensing outlet. The cradle can be designed as a drip tray for receiving the liquid coming out of the dispensing outlet when the drinking container is not placed on the tray. This emerging liquid can be the liquid dispensed during the beverage preparation process, the residue after beverage preparation, the cleaning liquid during the cleaning cycle, etc.

Summary of the Invention

[0004] Therefore, an object of the present invention is to provide a beverage preparation machine and a method for dispensing liquids that enable clean and safe use.

[0005] According to one embodiment, the present invention relates to a beverage preparation machine comprising: a liquid delivery unit for delivering liquid through the beverage preparation machine; a dispensing unit for dispensing, for example, the liquid delivered by the liquid delivery unit from the beverage preparation machine; and a collection unit fluid-connectable to the dispensing unit to selectively form a liquid path (for example, closed or bypassed) for collecting (for example, at least a portion of) the liquid dispensed by the dispensing unit.

[0006] Therefore, since the beverage preparation machine includes a collection unit that can be fluidly connected to the dispensing unit, a liquid path can be selectively formed to collect any liquid dispensed or discharged by the dispensing unit. Thus, dripping of liquid or beverage outside after dispensing can be avoided, so that the user's or the next user's drinking container will not be contaminated with, for example, residue of previously dispensed liquid. If a heated liquid is dispensed, burns can be avoided if residue is collected by the collection unit. Also, vapors that may be generated by heating the liquid inside the machine to dispense a heated liquid and that may escape from the dispensing unit can also be collected through the liquid path, thus further reducing the risk to the user, for example, from burns. In the case of a cleaning process, a liquid path may be formed to prevent the cleaning liquid from coming into contact with the user, or even from being dispensed onto a drinking container, for example, placed on a stand below the dispensing unit. In the context of the present invention, the term "cleaning" preferably includes rinsing, purification, washing, descaling, etc. Sterilization, and all other types of cleaning may be included. Thus, the “cleaning solution” can be any type of liquid to improve the cleanliness of the machine, such as heated / high-temperature liquids, water, descaling agents, disinfectants, sterilizers, etc. In short, in this way, the use of the beverage preparation machine is preferably cleaner and safer compared to the machines described above. It also minimizes the risk of cross-contamination.

[0007] The dispensing unit may preferably include an outlet port for dispensing liquid, for example, from a beverage preparation machine, preferably into a drinking container. Thus, a defined, for example, specifically directed and / or controlled, and therefore clean dispensing can be obtained.

[0008] The collection unit may preferably be equipped with an inlet port for fluid connection to the dispensing unit, preferably the outlet port, in order to form a liquid path. Thus, a clearly defined section can be provided for receiving and collecting the liquid dispensed by the dispensing unit at any desired time. Therefore, the liquid path can be optimized for very clean and safe collection of the liquid, and thus for the use of the corresponding machine.

[0009] When the collection unit is fluidly connected to the dispensing unit to form a liquid path, it may preferably include a cup-shaped housing for accommodating at least a portion of the dispensing unit, preferably at least the outlet port, preferably at the inlet port. Thus, the cup-shaped housing allows for secure enclosure of the dispensing unit or outlet port, and therefore a preferably securely closed liquid path when fluidly connected, thus enabling clean and safe collection of any liquid dispensed by the dispensing unit.

[0010] The collection unit may be movable, preferably relative to the dispensing unit, preferably at least at its outlet port, between a connection position for fluidly connecting the collection unit and the dispensing unit to form a liquid path, preferably at least at the inlet port, and a retraction position for enabling the dispensing unit to dispense liquid from the beverage preparation machine. These defined positions allow for a dedicated placement of the collection unit relative to the dispensing unit, enabling desired liquid dispensing at the retraction position and clean, safe, and reproducible liquid collection at the connection position. Thus, the formation of the liquid path and removal of the dispensing unit can be performed intuitively, minimizing handling errors.

[0011] The collection unit may be movable, preferably along a defined trajectory, by rotational and / or linear motion, more preferably at least at the inlet port and / or the dispensing unit, preferably at least at the outlet port. The defined mobility allows for defined movement, thus, on the one hand, creating a liquid path repeatedly, accurately and safely, and on the other hand, allowing the dispensing unit to be used for free dispensing. Release This makes this possible. This movement is preferably achieved by a parallelogram guide mechanism, which allows for a simple yet reliable configuration.

[0012] A beverage preparation machine may preferably further include biasing means, such as biasing elements, to enable a dispensing unit, preferably an outlet port, and a collection unit, preferably an inlet port, to be biased relative to each other toward either forming a fluid connection or not forming a fluid connection, preferably toward a connection position or a retraction position. Thus, reaching a predetermined relative position between these units can be supported. If the biasing means bias toward a fluid connection or connection position, a flow path can be easily obtained and safely maintained. If the biasing means bias toward not forming a fluid connection or toward a retraction position, little or no energy is required to maintain these units in a normal operating state.

[0013] The biasing mechanism may preferably include a spring and / or material and / or components of at least some of the collection unit and / or dispensing unit. This is preferably for preloading at least one of the collection unit and / or dispensing unit relative to each other. The spring is a standardized and therefore readily available component. If the biasing mechanism is incorporated into at least some of the material or specifications of each unit, the overall layout of the machine can be simplified and the number of parts can be reduced. As for materials, the biasing mechanism may be a one-piece rubber component, such as the edges of the inlet and / or outlet ports. As a design feature, the support arm of the collection unit may have a defined length to allow a defined flexibility. Also, the edges of the inlet and / or outlet ports may be structured or segmented to have a defined flexibility to allow the required biasing function.

[0014] A sealing element may be preferably provided between the dispensing unit, preferably the outlet port, and the collection unit, preferably the inlet port, to seal the liquid path when fluid is connected. Thus, the liquid path can be provided in a secure, leak-free, and therefore safe manner. Preferably, the sealing element may be provided integrally with the biasing means, for example, in the form of circumferential rubber edges of the inlet and / or outlet ports.

[0015] The collection unit may preferably be fluidly connected to a receiver for collecting liquid, preferably downstream from the inlet port. This allows for the storage of liquid and delays the removal or disposal of the collected liquid until a desired time, thereby increasing the practicality of the machine. It also allows for the safe storage of residues or other liquids. This is particularly advantageous when the collected liquid is a cleaning solution. Feedback means (e.g., lamp, display, speaker, etc.) may be provided, for example, by visual feedback (e.g., indicator lamp, display, etc.) or auditory feedback (e.g., warning sound, voice command, etc.), to indicate that the receiver needs to be emptied when it is full.

[0016] The receiver may preferably be a drip tray, and more preferably located below the dispensing unit. Thus, the receiver can be incorporated into a frequently existing feature of such a machine, thus facilitating the overall layout without affecting the dimensions and specifications of the machine.

[0017] The collection unit, and / or, if present, the receiver, can preferably be fluid-connected to or be fluid-connectable to the fluid delivery unit to form a closed circulation loop. Thus, the collected liquid can be reused as needed. This can be useful, for example, in a cleaning cycle that allows for the economical use of the required cleaning fluid.

[0018] The beverage preparation machine may preferably further include flow limiting elements, such as pinch valves, for selectively limiting or stopping the dispensing of liquid through the dispensing unit. This feature can, for example, enable a defined interaction between the edible product being transported within the dispensing unit and the liquid. Additionally, a cleaning solution may be retained in the machine for a defined cleaning period to allow for thorough cleaning of the machine.

[0019] The flow limiting element may preferably be movable between a flow limiting position that restricts or stops the flow of liquid through the dispensing unit and a flow position that allows for the free flow of liquid through the dispensing unit. Thus, the flow of liquid through the dispensing unit can be easily and precisely controlled.

[0020] The flow limiting element may preferably include a limiting head that is movable relative to the flexible fluid delivery line section (e.g., of a fluid delivery unit and / or dispensing unit), thereby selectively reducing or eliminating the cross-sectional area of ​​the fluid flow path through the fluid delivery line section, preferably at the flow limiting position. Thus, the limiting function can be easily provided. This layout also requires less maintenance.

[0021] The movement of the flow limiting element may preferably be at least partially related to the relative movement of the collection unit with respect to the dispensing unit. This preferably follows a combination of movements that are at least partially continuous, such that the flow limiting element is in the limiting position while the collection unit is in the retracted position, then the flow limiting element is in the flow position while the collection unit is in the retracted position, then the flow limiting element is in the flow position while the collection unit is in the connected position, and vice versa. This combination of movements simplifies the overall layout of the machine and facilitates access to each position. Therefore, misuse can also be avoided.

[0022] The beverage preparation machine may preferably further include a collection unit and / or a dispensing unit, and, if present, actuators for moving flow limiting elements as well. The actuators may move each component directly. This can be done, for example, via a gear train that may be provided between each component. The actuators may also move at least some of each component indirectly, for example by directly moving one of the other movable components. Thus, components moved directly and indirectly may be in contact (e.g., movably connected) or made to contact so that they move together at least partially in a coordinated motion.

[0023] The beverage preparation machine may preferably further include a UV lamp for irradiating the dispensing unit, preferably the outlet port, and / or the collection unit, preferably the inlet port, i.e., for exposing these components to ultraviolet light. Thus, the desired configuration of the thus exposed components for dispensing and / or forming the liquid pathways. Sterilization This can be achieved. This will also reduce cross-contamination.

[0024] A UV lamp may be preferably provided in the collection unit such that, when the fluid is connected to the dispensing unit, the UV lamp is directed toward the dispensing unit, preferably toward the outlet port. This allows the inlet port to be directed toward the dispensing unit when or before the liquid path is created. SterilizationIt may be made possible. Alternatively or additionally, the UV lamp may preferably be provided in the dispensing unit such that when the UV lamp is fluidly connected to the collection unit, it is directed towards the collection unit, preferably the inlet port. Thereby, before or during the creation of the liquid path, the outlet port can be Sterilization made possible. The UV lamp may also be Sterilization provided elsewhere as long as it enables ultraviolet irradiation of each component for the purpose.

[0025] The beverage preparation machine, preferably the liquid delivery unit, may preferably include a heater for heating the liquid within the liquid delivery unit. Thus, the liquid can be heated to prepare and / or dispense the heated liquid or beverage. Also, a liquid such as water may be heated for use in cleaning (e.g., rinsing) purposes. The water thus heated can then pass through the machine and the liquid path jite liquid delivery Even if well, preferably also recirculated It's fine. .

[0026] The beverage preparation machine, preferably the liquid delivery unit, may preferably include a pump for delivering the liquid through the beverage preparation machine (i.e., including the liquid path if present). Thus, the liquid can be easily delivered and (re)circulated.

[0027] The beverage preparation machine may preferably further include a control unit configured to selectively fluidly connect the collection unit to the dispensing unit by controlling the pump to deliver the liquid and / or by controlling an actuator to move the collection unit relative to the dispensing unit, and / or to restrict or stop the liquid flow by preferably moving a flow restriction element. Of course, the control unit may also be configured to heat and / or cool the liquid by preferably controlling a heater (i.e., for heating) and / or a cooling unit (i.e., for cooling).

[0028] In another aspect, the present invention relates to a method for dispensing a liquid, A step of supplying liquid through a beverage preparation machine, preferably through a liquid supply unit of a beverage preparation machine as defined herein, The process involves dispensing the liquid, which has been delivered by the liquid delivery unit, through the dispensing unit of the beverage preparation machine, A step of selectively fluid-connecting a collection unit of a beverage preparation machine to a dispensing unit in order to form a liquid path for collecting (for example, at least a portion thereof) of the liquid dispensed by the dispensing unit, This applies to methods that include [specific methods].

[0029] Therefore, for the reasons already stated herein with respect to beverage preparation machines, a method for dispensing liquids is provided that enables clean and safe use of beverage preparation machines. To avoid repetition, refer to the findings and advantages stated herein.

[0030] The step of dispensing the liquid may preferably include the step of preparing a beverage based on the liquid in a beverage preparation chamber, preferably upstream of or inside the dispensing unit. The beverage preparation chamber may be, for example, a mixing chamber or a dispensing chamber. For example, a beverage additive section may be provided (for example, as part of the dispensing unit) for dispensing additives to be mixed with the liquid. Alternatively, edible products may be placed in capsules inserted into the beverage preparation chamber for dispensing and / or leaching and / or dissolving the edible products. Thus, the liquid may be further enhanced and / or strengthened, for example, by interaction with the edible products, to produce the corresponding beverage to be dispensed. Therefore, the step of dispensing the liquid may further include the step of dispensing the prepared beverage through a dispensing unit.

[0031] Preferably, the dispensing of the beverage can be restricted or stopped at the start of beverage preparation, and the dispensing of the prepared beverage can be started after a predetermined period of time following the start of beverage preparation. This step allows the liquid to be retained inside the machine, for example, to allow sufficient interaction with the food product for beverage preparation, or to thoroughly clean the machine, or simply to avoid dripping or dispensing outside of operation or, for example, between two consecutive dispensing commands by the user.

[0032] The liquid pathway may preferably be formed before the process of dispensing the liquid or prepared beverage begins, and thereafter, after the process of dispensing the liquid or prepared beverage has begun and a predetermined duration has elapsed, the dispensing unit will be able to freely dispense the liquid or prepared beverage from the collection unit. release This allows for the collection of unnecessary initial liquid volume. This is because the initial liquid volume may not yet contain a fully prepared beverage, or it may contain some old residue inside the machine. Also, in the case of heated liquids, some vapor may be generated inside the machine, and this vapor can therefore be collected to avoid the risk of burns to the user, for example.

[0033] The liquid pathway may preferably be formed after the process of dispensing the liquid or prepared beverage is completed. This avoids the dispensing or dripping of any residue. Furthermore, the dispensing unit (e.g., the outlet port) can be reliably stored away from operation to avoid cross-contamination. In addition, if a UV lamp is present, the inlet and outlet ports Sterilization It can be easily done.

[0034] The fluid connection step may preferably include relative movement between the dispensing unit and the collection unit to fluidly connect the outlet port of the dispensing unit and the inlet port of the collection unit. Preferably, these units can move relative to each other between the aforementioned retraction position and connection position. Thus, a fluid path can be easily formed, and if necessary, the dispensing unit can be moved Release It is possible.

[0035] The step of collecting the liquid (or at least a portion thereof) may preferably include the steps of collecting each liquid or prepared beverage into a receiving container and / or recirculating the liquid to a liquid delivery unit. Thus, the collected liquid can be easily stored. For example, for cleaning purposes, the liquid may be a cleaning solution that can be recirculated to economically clean the machine.

[0036] The liquid may be preferably heated or cooled before or during liquid delivery. Thus, hot or cold beverages may be served. The heated liquid may also be used for cleaning (e.g., rinsing) purposes and may be preferably recirculated as described herein for economical cleaning of the machine.

[0037] The dispensing unit, preferably the outlet port, and / or the collection unit, preferably the inlet port, are preferably washed before, during, and / or after the dispensing and / or collection of the liquid or prepared beverage. Sterilization This can be done. Therefore, the lifespan of the machine can be extended, and the safety of the dispensed product can be increased, especially if it is intended for ingestion. Cleaning or Sterilization This can be done by delivering or circulating the corresponding (cleaning) liquid through the machine and preferably through a liquid pathway (i.e., including the liquid pathway). At the end of this process, the corresponding liquid may be collected via a collection unit, for example, in a receiver. Sterilization The process may preferably include, for example, irradiating the dispensing unit and / or collection unit with ultraviolet light using a UV lamp as described herein. This is preferably done when the fluid connection is formed and therefore the flow path is created. [Brief explanation of the drawing]

[Figure 7] A schematic diagram of a beverage preparation machine according to a third embodiment of the present invention is shown. [Modes for carrying out the invention]

[0039] The figures illustrate different embodiments of the beverage preparation machine 1, as well as its specific details and components. Embodiments in Figures 1 to 6 exemplify pour-type or leach-type beverage preparation machine 1. Embodiment in Figure 7 shows a dispenser-type beverage preparation machine 1. The beverage preparation machine 1 may be adapted for use by consumers who (if necessary) request beverages from the beverage preparation machine 1. That is, the beverage preparation machine 1 may be adapted to dispense or pour beverages that are ready for consumers to drink, i.e., ready-to-drink beverages. The beverage preparation machine 1 is not limited to a particular design. Preferably, the beverage preparation machine 1 is designed for business-to-business (B2B) and / or business-to-consumer (B2C) use. For example, the beverage preparation machine 1 may be designed as a vending machine in B2B (hotels, restaurants, cafes (i.e., "HoReCa"), fitness centers, offices, etc.) and / or B2C (e.g., homes) (airports, malls, public areas, etc.). The beverage preparation machine 1 may be designed as a vending machine, water dispenser, and / or household appliance device. The beverage preparation machine 1 may be designed to be mounted or positioned on a wall (wall-mounted), base, and / or tabletop, and / or the beverage preparation machine 1 may have a freestanding design. The beverage preparation machine 1 may be equipped with power supply connections to supply electrical energy to each component of the beverage preparation machine 1.

[0040] The beverage preparation machine 1 includes a liquid delivery unit 2 for delivering liquid through the beverage preparation machine 1. A liquid delivery unit 2 of a dispenser-type beverage preparation machine 1 is shown exemplary in Figure 7. The liquid delivery unit 2 may include at least one or more liquid delivery lines 20 to form a passage for delivering liquid through the liquid delivery unit 2 and therefore through the beverage preparation machine 1. The liquid delivery unit 2 may also include one or more pumps 21 for delivering liquid through the beverage preparation machine 1 by corresponding pump action. The pumps 21 may also be part of another part of the beverage preparation machine 1, insofar as they are capable of delivering liquid through the beverage preparation machine 1.

[0041] The liquid delivery unit 2 may further comprise a heater 22 for heating the liquid within the liquid delivery unit 2. The heater 22 may also be part of another part of the beverage preparation machine 1, insofar as it is capable of heating the liquid being delivered or to be delivered through the beverage preparation machine 1.

[0042] The liquid delivery unit 2 may further preferably include a cooling unit 23 (which here has a chiller 230 and a compressor 231 for circulating a cooling medium through the chiller 230) for cooling the liquid within the liquid delivery unit 2. The cooling unit 23 or its chiller 230 as shown in Figure 7 is provided in a buffer tank 24. The buffer tank 24 is preferably part of the liquid delivery unit 2 for storing and regulating (e.g., cooling) a predetermined amount of liquid (e.g., water) that is ready for dispensing. Of course, the cooling unit 23 may also be part of another part of the beverage preparation machine 1, insofar as it is capable of cooling the liquid being delivered or to be delivered through the beverage preparation machine 1.

[0043] The beverage preparation machine 1 further comprises a dispensing unit 3 for dispensing liquid supplied by or through a liquid supply unit 2. The dispensing unit 3 is shown in Figures 1 to 6 and schematically shown in Figure 7. The dispensing unit 3 may be equipped with an outlet port 30 for dispensing liquid. The liquid can be dispensed or discharged from the dispensing unit 3, for example, by gravity, or by the liquid supply action of the liquid supply unit 2, preferably a pump 21. A drinking container V may be positioned below the dispensing unit 3. The beverage preparation machine 1 may be equipped with a support 4 positioned below the dispensing unit 3 for holding a drinking container V to receive the dispensed liquid. Here, the height of the support 4 can be adjusted to optimally position the drinking container V relative to the dispensing unit 3, regardless of the size of the drinking container V.

[0044] The beverage preparation machine 1 may further include a drip tray 50, preferably located below the dispensing unit 3, as shown in Figure 7. Here, the drip tray 50 is independent of the base 4, but in another embodiment, the drip tray 50 may also be integrally formed with the base 4.

[0045] As shown in the embodiments in Figures 1 to 6, the beverage preparation machine 1 may further include a flow limiting element 6 for selectively limiting or stopping the dispensing of liquid through the dispensing unit 3. Here, the flow limiting element 6 is designed as a pinch valve. As can be clearly seen by comparing Figures 4 and 5, the flow limiting element 6 may be movable between a flow limiting position (see Figure 5) that limits or stops the liquid flowing through the dispensing unit 3 and a flow position (see Figure 4) that allows for the free flow of liquid through the dispensing unit 3.

[0046] As shown in Figures 1 to 6, the flow limiting element 6 may include a limiting head 60 that is movable relative to the flexible liquid delivery line section 31, thereby selectively reducing or eliminating the cross-sectional area of ​​the liquid flow path 32 passing through the liquid delivery line section 31 at a preferred flow limiting position as shown in Figure 5.

[0047] The beverage preparation machine 1 may include an actuator 7, such as an electric motor, for moving the flow limiting element 6 preferably between a flow position and a flow limiting position. As clearly shown in Figures 1 to 3, the actuator 7 can be functionally coupled directly to the flow limiting element 6 in order to move the flow limiting element 6 directly. Thus, the rotational motion of the actuator 7 can be converted into linear motion of the flow limiting element 6, for example, via a gear train 70 having a pinion gear 71 of the actuator that meshes with a gear rack 72 integrally formed with the flow limiting element 6.

[0048] The beverage preparation machine 1 further comprises a collection unit 8. The collection unit 8 is fluid-connectable to the dispensing unit 3 to selectively form a liquid path P (see Figures 1, 6, and 7) for collecting the liquid dispensed by the dispensing unit 3.

[0049] The collection unit 8 may have an inlet port 80 for fluid connection to the dispensing unit 3, preferably its outlet port 30, in order to form a liquid path P. The collection unit 8 may have a cup-shaped housing 81 for accommodating at least a portion of the dispensing unit 3, preferably at least the outlet port 30, when the collection unit 8 is fluidly connected to the dispensing unit 3 at its inlet port 80 to form a liquid path P. This can be clearly seen in Figures 1 and 6, which show the cup-shaped housing 81 placed on the outlet port 30 of the dispensing unit 3 to form a liquid path P. This cup shape can also be clearly seen in Figure 3.

[0050] The collection unit 8, preferably at least its inlet port 80, may be movable relative to the dispensing unit 3, preferably at least its outlet port 30, between a connection position (see Figures 1, 6, and 7 (dashed line)) for fluidly connecting the collection unit 8 and the dispensing unit 3 to form a liquid path P, and a retraction position (see Figures 2-5 and 7 (dotted line)) for enabling the dispensing unit 3 to dispense or discharge liquid from the beverage preparation machine 1 into a drinking container V, for example, as shown in Figure 7. In the illustrated embodiment, relative movement between the dispensing unit 3 and the collection unit 8 is achieved by the dispensing unit 3 being fixedly positioned and the collection unit 8 being movable. In another embodiment, relative movement may also be achieved by the dispensing unit 3 being movable and the collection unit 8 being fixedly positioned, or by both being movable.

[0051] The collection unit 8 and preferably its inlet port 80 and / or the dispensing unit 3 and preferably at least its outlet port 30 may be movable by rotational motion and / or linear motion, preferably along a defined trajectory. In the embodiments of Figures 1 to 6, the movement of the collection unit 8 is achieved by a parallelogram-shaped guide mechanism 82 that produces a combination of rotational and linear motion along a defined trajectory. In the embodiment of Figure 7, the collection unit 8 or at least its inlet port 80 is exemplarily shown to be movable by rotational motion about a fixed axis of rotation X. This rotational motion preferably allows the collection unit 8 to move, i.e., pivot, between a closed position (see dotted line in Figure 7) and a connected position (see dashed line in Figure 7).

[0052] As can be seen particularly from Figures 4 to 6, the movement of the flow limiting element 6 may be at least partially related to the relative movement of the collection unit 8 with respect to the dispensing unit 3. As described above, the flow limiting element 6 is here preferably linearly movable along the direction of movement M. On the opposite side of the limiting head 60 along the direction of movement M, the flow limiting element 6 may have a contact surface 61 facing toward the trigger portion 83. As can be seen in the comparison of Figure 5 and Figure 4, when the flow limiting element 6 is moved linearly away from the dispensing unit 3 or its liquid delivery line portion 31, the contact surface 61 approaches the trigger portion 83. When the flow limiting element 6 is moved further toward the trigger portion 83 along the direction of movement M, the contact surface 61 comes into contact with the trigger portion 83, and when moved further as shown in Figure 6, the flow limiting element 6 operates so that the collection unit 8 is moved, preferably from the retracted position to the connected position, via the trigger portion 83, thereby forming the liquid path P as shown in Figure 6. Thus, the movement of the flow limiting element 6 and the movement of the collection unit 8 may be at least partially related to each other.

[0053] This movement can preferably be associated with the flow limiting element 6 being in the limiting position while the collection unit 8 is in the closed position (see Figure 4), then the flow limiting element 6 being in the flow position while the collection unit 8 is in the retracted position (see Figure 5), then the flow limiting element 6 being in the flow position while the collection unit 8 is in the connected position (see Figure 6), and vice versa. Thus, the collection unit 8 (as shown in the embodiments of Figures 1 to 6) and / or the dispensing unit 3 can thus be moved indirectly, by the direct movement of one of the other movable parts (e.g., via the actuator 7), i.e., here exemplary, via the flow limiting element 6.

[0054] The beverage preparation machine 1 may further include biasing means 9 to allow the dispensing unit 3, preferably its outlet port 30, and the collection unit 8, preferably its inlet port 80, to be biased relative to each other. In the illustrated embodiment, these elements 3 and 8 are biased toward the side that does not form a fluid connection, and therefore preferably toward the retraction position. Thus, the collection unit 8 is guided toward the retraction position when the flow limiting element 6 is moved (returned) in the direction M toward the dispensing unit 3 or its fluid delivery line section 31. However, the dispensing unit 3 and the collection unit 8 can also be biased relative to each other, if necessary, toward the side that forms a fluid connection, and therefore preferably toward the connection position.

[0055] Figure 1 also shows an embodiment in which, if necessary, the collection unit 8 can be selectively moved independently of the flow limiting element 6 by an actuator (not shown). On the other hand, the flow limiting element 6 and the collection unit 8 may also be functionally connected so that their movements are always linked to each other. If there are components that are moved directly or indirectly by the actuator 7, which components are moved directly or indirectly by the actuator 7 can be selected as desired, and the present invention is not limited to any particular layout. Furthermore, any of the described movements may be manually operated or triggered as necessary.

[0056] As shown in the embodiments in Figures 1 to 6, the biasing means 9 described above may comprise a spring, preferably a tension spring 9. The biasing means 9 may also comprise at least some of the materials and / or specifications of the collection unit 8 and / or dispensing unit 3.

[0057] A sealing element 10 may be provided to seal the liquid path P when a fluid connection is made between the dispensing unit 3, preferably its outlet port 30, and the collection unit 8, preferably its inlet port 80, as shown in Figures 1 and 6.

[0058] As illustrated in Figure 7, the collection unit 8 may be fluidly connected to a receiver 5 for collecting liquid, preferably located downstream from the inlet port 80. As seen in Figure 7, the receiver 5 may be identical to or integrated with the drip tray 50 to facilitate the collection and disposal of residue.

[0069] The following describes methods for dispensing liquids.

[0070] In the first step, liquid is delivered through a liquid delivery unit (preferably a liquid delivery unit 2) of a beverage preparation machine (preferably a beverage preparation machine 1 according to the present invention).

[0071] In the second step, the liquid supplied by the liquid supply unit 2 is dispensed via or through the dispensing unit (preferably dispensing unit 3) of the beverage preparation machine 1.

[0072] In the third step, the collection unit (preferably collection unit 8) of the beverage preparation machine 1 is selectively fluid-connected to the dispensing unit 3 to form a liquid path (preferably liquid path P) for collecting the liquid dispensed by the dispensing unit 3.

[0073] The step of supplying the liquid may preferably include the step of preparing a beverage based on the liquid in a beverage preparation chamber (preferably a beverage preparation chamber 33) upstream of or inside the dispensing unit 3. The step of dispensing the liquid may then include the step of dispensing the prepared beverage via or through the dispensing unit 3.

[0074] As shown in Figure 5, the dispensing of the beverage can be restricted or stopped. This may be useful, for example, for the preparation of the beverage, for example, to allow sufficient leaching or dissolution of food product C. After a predetermined period of time following the start of beverage preparation, the dispensing of the prepared beverage may be started, as shown in Figure 4. This can be done by appropriately moving the flow restriction element 6 between the restricted position in Figure 5 and the flow position in Figure 4.

[0075] The liquid path P may be formed before the process of dispensing the liquid or prepared beverage begins, as shown in Figure 6. This may be useful to protect the dispensing unit 3 or its outlet port 30 from contamination. Also, if a heated liquid is being dispensed, vapor may be released from the dispensing unit 2 during beverage preparation or at the start of liquid / beverage delivery. This vapor can then be collected through the connecting unit 8, thus reducing the risk of burns to the user, for example. Dispensing the liquid or prepared beverage may have already begun while the liquid path P is still being formed. Thus, the initial amount of potential vapor or liquid / beverage can be collected as needed. After a predetermined period of time, the dispensing unit 3 can then freely dispense the liquid or prepared beverage into, for example, a beverage container V, from the collecting unit 8. Release It is possible.

[0076] The liquid pathway P can also be formed after the process of dispensing the liquid or prepared beverage is complete, as shown in Figure 6. This ensures that any residue dripping from the dispensing unit 3 can be reliably collected.

[0077] The fluid connection process may include relative movement between the dispensing unit 3 and the collection unit 8. This is to preferably fluidize the outlet port of the dispensing unit 3 (preferably the outlet port 30) and the inlet port of the collection unit 8 (preferably the inlet port 80).

[0078] The step of collecting (at least a portion of) the liquid may include the step of collecting each liquid or prepared beverage into a receiving container 5, such as a drip tray 50. Alternatively or additionally, the step of collecting (at least a portion of) the liquid may include, for example, in the washing step, the step of recirculating the liquid to a liquid delivery unit 2 so that the corresponding liquid is circulated through the beverage preparation machine 1.

[0079] The liquid is heated or cooled before or during its delivery, so that hot or cold beverages can be provided. The heated liquid may also be used for cleaning (e.g., rinsing) purposes, for example, in a closed circulation loop via the collection unit 8.

[0080] The dispensing unit 3, preferably the outlet port 30, and / or the collection unit 8, preferably the inlet port 80, are preferably washed before, during, and / or after the dispensing and / or collection of liquid or prepared beverages. Sterilization Possible. Washing or Sterilization This can be obtained, for example, by transporting the corresponding liquid, such as heated water, along the corresponding liquid path P, as described above. In a preferred embodiment, Sterilization The process preferably includes, for example, irradiating the dispensing unit 3, preferably the outlet port 30, and / or the collection unit 8, preferably the inlet port 80, with ultraviolet light using UV lamps 11, 12.
