Description

[0001] System and method for brewing a beverage

[0002] Field of the invention

[0003] The present invention lies in the field of machines for producing a beverage, in particular in the field of machines for brewing a beverage. The present invention is directed to a system for brewing a beverage and a corresponding method for brewing a beverage.

[0004] Background of the invention

[0005] Typically, machines for brewing a beverage, particularly coffee, and more particularly espresso coffee, may either be full-automatic or of portafilter-type, the latter also known as semi-automatic. A full-automatic machine can handle every step of brewing with, for example, the press of a button. It can automatically grind, dose, tamp, and brew. In contrast, a portafilter (or semi-automatic) espresso machine requires manual effort: the user grinds, tamps, controls the brewing time, as well as handles of a portafilter. An alternative two the afore-mentioned types of machines may also be machines based on capsules.

[0006] The teaching of EP 2 811 876 Bl relates to a coffee maker comprising at least one removable portafilter that, in order to carry out brewing, can be inserted into a holder on the coffee machine provided for this purpose. The coffee maker further comprises a first means for producing and dispensing hot water under pressure, and at least one coffee mill. A device-based simplification of the machine while still maintaining specifiable and consistent quality of the beverage is achieved by providing a second means for repeated, pressure-tight closing and opening of the portafilter inserted into the holder and by providing a third means for introducing coffee powder from the coffee mill into the open portafilter that is inserted into the holder.

[0007] US 2010 / 080886 Al discloses a programmable apparatus for making coffee that includes a hopper for holding coffee beans; a grinding element for receiving the coffee beans and grinding them to produce ground coffee; and a brewing chamber for receiving programmable quantities of ground coffee and combining the ground coffee with quantities of hot, pressurized water. The programmable apparatus for making coffee also includes a piston for compressing the ground coffee, the piston being arranged to enter the brewing chamber at an open end thereof; an O-ring fitted to the outside of the piston so as to maintain a pressure-tight seal against the wall of the brewing chamber; and a programming element for selectively determining a quantity C of ground coffee to be combined with a quantity W of water in the brewing chamber, the brewing chamber being capable of accommodating more than 14 grams of ground coffee.

[0008] WO 93 / 20736 Al discloses a pressure-filter device consisting of a housing section (with a piston which can be moved vertically thereinto. On the housing section there is a filter carrier which can rotate horizontally about the pivot axis and is fitted with a filter fillable with ground coffee. With the piston lowered into the filter (operative position), the latter forms therewith a pressure chamber enclosing the ground coffee into which the pressurised hot water is forced on the piston side via a line and the prepared espresso beverage flows on the filter side through at least one outlet aperture. With the piston raised, the filter carrier with the filter can be pivoted out of the operating region of the piston about a vertical axis. Thus the pivoting range of the filter carrier extends from its operative position to its filling position in which the filter is accessible from outside. It is only in the operative position of the filter carrier that the latter is secured in relation to the housing section against vertical movement by supports formed on both the filter carrier and the housing section. The system of the invention provides substantially easier handling of the filter in that it is more easily filled with ground coffee and emptied without the need for an operator to hold the filter carrier. At the same time, the filter carrier is held firmly in the housing section axially in its operative position without any significant distortions being caused to these components.

[0009] The teaching of WO 02 / 051290 Al refers to machines for the preparation of espresso coffee or similar beverages. A charger filter holder is equipped with an elastically deformable element designed to eject the block of used coffee grounds from the infusion chamber after the infusion process. The charger is attached by means of a bayonet fitting to the metal support sheath, which is maintained at a constant temperature by direct contact with the heat accumulator / exchanger for the infusion water. The construction methods for the bayonet fitting reduce wear on the spiral guides and make replacement of worn parts easier. The advantages are: easy ejection of the used block, constant temperature of the infusion chamber and longer duration of the bayonet fitting.

[0010] US 9 066 623 B2 discloses a beverage making appliance which uses a specialized beverage container and a related method of brewing a beverage. The container includes a cupshaped body having a floor, a circumferential wall, and a top opening, a filter element positioned above the floor, at least one aperture formed in the floor, and a cover releasably attached to the cup body and covering the top opening. The appliance includes a base adapted to receive a beverage receptacle, a reservoir, a housing, a brewing tray in mechanical communication with the housing and dimensioned to receive a container containing at least one drink ingredient having particles of a first size, a grinding mechanism and a water delivery mechanism to selectively deliver water from the reservoir to one of a brewed beverage outlet in fluid communication with the receptacle, and a hot- water outlet.

[0011] Full-automatic machines may be ideal in terms of convenience and consistency, and they may be easy to operate. However, the quality of the espresso coffee from full-automatic machines may not be ideal. These machines may also be bulky and expensive.

[0012] Portafilter-type machines may offer more customization and control over, for example, flavor, and may produce high-quality espresso. However, they may require expertise to be operated, for example in the dosing and in the tamping, as well as in the general handling of the portafilter, which is a detachable component. Portafilter-type machines may also require extensive effort for cleaning. These machines may also be bulky and expensive.

[0013] Machine relying on capsules may not achieve the pressure needed at extraction to reach a good quality of espresso coffee.

[0014] Summary of the invention

[0015] It is an object of the present invention to alleviate, at least in part, at least some of the shortcomings of existing technologies.

[0016] The present invention alleviates, at least in part, at least some of the shortcomings of existing technologies. In particular, the present invention is directed, at least in part, to a system for brewing a beverage that can, inter alia, be compact, be easy-to-use, achieve high-quality espresso, be easy to clean, and / or not involve a risk of spilling ground or brewing materials when is operated. The present invention is also directed, at least in part, to a corresponding method.

[0017] In a first aspect, the present invention relates to a system, comprising a brewing compartment, a portioning means, a conveying assembly, a plunging mechanism.

[0018] In some embodiments, the brewing compartment may comprise a brewing chamber with a first opening opposite to a second opening. The first opening may be configured to receive a dose of grounds. Additionally, or alternatively, the second opening may be configured to deliver a brewed beverage.

[0019] In some embodiments, the portioning means may be configured to portion the dose of grounds out of grounds. For example, the portioning means may be configured to portion the dose of grounds out of coffee grounds. The portioning means may further be configured to place the dose of powder into the brewing chamber, particularly through the first opening. Furthermore, the portioning means may be configured to place the dose of grounds into the brewing chamber by letting the dose of grounds fall into the brewing compartment, particularly through the first opening.

[0020] The conveying assembly may be embedded in the system. In other words, it may not be detached from the system during normal operation of the system. In still other words, it may not be detached from the system when the system is utilized to brew a beverage. In some embodiments, the conveying assembly may be a sliding assembly. Moreover, the conveying assembly may comprise a filter. Said filter may have a cross-section essentially corresponding to the second opening.

[0021] Embodiments of the present invention may be advantageous at least because the conveying assembly may be embedded in the system. In prior-art, conventional portafiltertype coffee machines, instead, the portafilter typically requires skilled handling by an experienced barista. It must be attached and detached during normal use to produce high- quality espresso. By contrast, embodiments of the present invention may provide the benefit of delivering high-quality espresso without requiring barista expertise or the inconvenience of managing a portafilter, which in conventional machines may be manually secured and removed for each use.

[0022] The conveying assembly may be configured to be moved reciprocally between at least a first position and a second position. It will be understood that a reciprocal movement may refer to a back and forth movement between two points in a repeated, alternating manner. In some embodiments, the conveying assembly may be configured to be moved reciprocally, preferably slid, and preferably manually, between at least a first position and a second position. In the first position, the filter may be essentially aligned with the second opening. In the first position, the filter may be configured to receive and hold the dose of grounds from the portioning means. In the second position, the conveying assembly may be configured to leave the second opening unobstructed.

[0023] In some embodiments the plunging mechanism may comprise a stamp. Moreover, the plunging mechanism may be a stamping mechanism. For example, the plunging mechanism may be a stamping mechanism for coffee grounds and / or coffee powder. The stamp may be configured to snug-fit, in a piston-like fashion, into the brewing chamber. The snug-fit tolerance between the stamp and the brewing chamber may be below 0.2 mm, preferably below 0.1 mm, more preferably below 0.05 mm. The stamp may be configured to move in an essentially linear and reciprocal motion within the brewing chamber.

[0024] In some embodiments, the plunging mechanism may be configured to be moved reciprocally between a rest position and at least a locking position. Additionally, or alternatively, the plunging mechanism may be configured to be moved reciprocally, preferably manually, between a rest position and at least a locking position. In the rest position, the plunging mechanism may be configured to allow the portioning means to place the dose of grounds into the brewing compartment. In the at least one locking position, the plunging mechanism may be configured to plunge the stamp into the brewing chamber, towards the second opening. In the at least one locking position, the plunging mechanism may further be configured to close the brewing chamber via the stamp, particularly in a pressure-tight manner and when the conveying assembly is in the first position. In the at least one locking position, the plunging mechanism may further be configured to perform, via the stamp, the tamping of the dose of grounds held by the filter.

[0025] Embodiments of the present invention may offer advantages, such as enabling the tamping of coffee grounds to be performed without relying on barista expertise. By simply moving the plunging mechanism in the locking position, optimal tamping may be achieved.

[0026] In some embodiments, the plunging assembly may be configured to be moved reciprocally between the at least one locking position and at least an expelling position. Additionally, or alternatively, the plunging assembly may be configured to be moved reciprocally, preferably manually, between the at least one locking position and at least an expelling position. In the at least one expelling position, the plunging mechanism may be configured to plunge the stamp into the brewing chamber further towards the second opening than in the at least one locking position. In the at least one expelling position, the plunging mechanism may be configured to push, via the stamp, content of the brewing chamber out of the brewing chamber, particularly through the second opening.

[0027] Embodiments of the present invention may be advantageous at least because, for example, they may enable used coffee grounds to be expelled from the system quickly and efficiently. By simply moving the plunging mechanism to the expelling position, used coffee grounds may be expelled and the brewing chamber may therefore be easily cleaned. In prior-art portafilter-type coffee machines, instead cleaning often involves detaching the portafilter, which can result in used coffee grounds being scattered around the machine or, in general, requires more user involvement. In contrast, embodiments of the present invention ensure a simple, quick, and efficient cleaning process after brewing a beverage.

[0028] It will be understood that the plunging mechanism may be reciprocally and / or continuously moved between the rest position and the expelling position, and that the at least one locking position lies in between the rest position and the expelling position.

[0029] In some embodiments, the system may be for brewing a beverage. Further, the beverage may be coffee. Moreover, the beverage may be espresso coffee.

[0030] In some embodiments, the brewing chamber has an essentially cylindrical shape. The first opening and the second opening essentially may take up the two essentially flat bases of the cylindrical shape. The peripheral region of the second opening may comprise a sealing ring groove, configured to receive a seating ring for establishing a pressure-tight sealing. The peripheral region of the second opening may comprise rails, configured to engage rail grooves.

[0031] In some embodiments the system may comprise at least a vibration component, configured to generate at least a vibrating signal. The vibrating signal may be configured to enable the dose of grounds to be subject to a vibration. Further, the vibrating signal may be configured to enable the brewing chamber and / or the filter to vibrate.

[0032] Embodiments of the present invention may be advantageous at least because of the vibrating signal, enabling the dose of grounds to be subject to a vibration. The preparation of the dose of grounds, e.g. coffee grounds, may be essential for the brewing result. Once the dose of grounds, e.g coffee powder, has been portioned, the system may automatically trigger a vibrating signal. This eliminates any cavities that may have formed after the dose of grounds, e.g coffee powder, was inserted, e.g. by falling, in the brewing chamber and ensures that the powder settles optimally in the brewing chamber. Subsequent tamping and / or pressing with a main lever can produce the best possible results.

[0033] In some embodiments, the plunging mechanism may comprise a main lever. The plunging mechanism may comprise a main cylinder. Furthermore, the main lever may be coupled to the main cylinder such that, when the main lever is engaged, particularly by a user, the main cylinder may rotate around the axis of the main cylinder. The plunging mechanism may also comprise a connecting element, coupling the main lever to the stamp, such that when the main lever is engaged, particularly by a user, the stamp may move in an essentially linear motion within the brewing chamber. The axis of the main cylinder may be essentially perpendicular to said essentially linear motion within the brewing chamber. The plunging mechanism may comprise at least a locking pin, configured to be snug-fit, in a piston-like fashion, into at least a hole provided along an axial direction of the main cylinder on at least one of the bases of the main cylinder. The at least one hole may be a non-centered hole. Moreover, the at least one locking pin may be biased, preferably by at least a locking spring, to stick out of the at least one hole. The at least one locking spring may be positioned into the at least one hole, such that the at least one locking pin may be biased by the at least one locking spring to stick out of the at least one hole. The at least one locking spring may deliver a maximum force between 3 N and 40 N, preferably between 7 N and 25 N, more preferably between 10 N and 20 N.

[0034] In some embodiments the plunging mechanism may comprise at least a clamping element. For example, at least one clamping element may be a screw-on jaw. The at least one clamping element may comprise at least a slotted hole. The at least one clamping element may be coupled to at least one of the bases of the main cylinder such that the at least one clamping element may push the at least one locking pin into the at least one hole, when the plunging element is in the rest position. In other words, the at least one clamping element may act against the bias provided by the spring. The at least one clamping element may be coupled to at least one of the bases of the main cylinder such that the at least one locking pin may be allowed to stick out of the at least one hole and engage a first terminal portion of the at least one slotted hole, when the plunging element is in the locking position. In other words, the first terminal portion of the slotted hole may define the locking position. The least one clamping element may be coupled to at least one of the bases of the main cylinder such that the at least one locking pin may be allowed to stick out of the at least one hole and engage a second terminal portion of the at least one slotted hole, when the plunging element is in the expelling position. In other words, the second terminal portion of the slotted hole may define the expelling position.

[0035] The main lever may be advantageously configured to generate the force required to press the dose of grounds, e.g. coffee powder. As soon as the dose of grounds has been pressed sufficiently, the main lever engages automatically. In other words, the at least one locking position of the plunging mechanism may define, in an automatic and easy manner, at least an optimal pressing condition for the dose of grounds.

[0036] Additionally, or alternatively, the plunging mechanism may comprise an unlocking mechanism. The unlocking mechanism may comprise at least an unlocking means. The at least one unlocking means may comprise a release button. The at least one unlocking means may be coupled to the at least one clamping element such that when the unlocking means is engaged, preferably by a user, if the at least one locking pin is engaged to any portion of the at least one slotted hole, the at least one locking pin may be pushed into the at least one hole. Sais pushing may be achieved by an unlocking spring, comprised in the unlocking mechanism, and configured to be activated by the at least one unlocking means. After said pushing, the plunging mechanism may be configured to be brought to the rest position.

[0037] In some embodiments the stamp may comprise a sealing ring groove, configured to receive a seating ring for establishing a pressure-tight sealing. The sealing ring groove may be located along the surface of the stamp that directly faces the inner walls of the brewing chamber.

[0038] In some embodiments, the conveying assembly comprise a slider. The slider may comprise a filter carrier, configured to hold the filter. The slider may further comprise the rail grooves. The conveying assembly may comprise a conveying assembly activation means. The conveying assembly activation means may also comprise a sliding handle. The conveying assembly activation means may be coupled to the slider such that the conveying assembly may be configured to be slid along the rails, the rails engaging the rail grooves, between the at least first position and second position. The conveying assembly activation means may be coupled to the slider such that the conveying assembly may be configured to be slid, preferably manually, along the rails, the rails engaging the rail grooves, between the at least first position and second position.

[0039] In some embodiments, the portioning means may comprise a portioning lever. The portioning means may comprise a gear wheel. Moreover, the gear wheel may be a freewheel. The portioning means may also comprise a cover. The portioning means may comprise a portioning disc. The portioning disc may be configured to snug-fit into the cover. The portioning disc may comprise at least a portioning hole, provided along an axial direction of the portioning disc. The at least one portioning hole runs from a base of the portioning disc to another base of the portioning disc. The openings of the at least one portioning hole are directly adjacent to inner surfaces of the cover. Moreover, the at least one portioning hole may be cylindrical. The at least one portioning hole may also be a noncentered hole. Moreover, the portioning lever may be coupled to the portioning disc via the gear wheel such that, when the portioning lever is engaged, preferably by a user, the portioning disc may rotate around the axis of the portioning disc. The portioning disc may be configured to rotate cyclically between at least between a receiving position and a placing position. The cover may have at least a first cover hole, in correspondence to the at least one portioning hole when the portioning disc in in the receiving position. The cover may have at least a second cover hole, in correspondence to at least one the portioning hole when the portioning disc in in the placing position. In the receiving position, the at least one portioning hole may be configured to receive the grounds, preferably through the at least one first cover hole. In moving from the receiving position to the placing position, the at least one portioning hole may be configured to portion the dose of the grounds by moving away from the at least one first cover hole. In the placing position, the at least one portioning hole may be configured to place the dose of grounds into the brewing chamber, preferably by letting the dose of grounds fall into the brewing chamber.

[0040] Embodiments of the present invention may be advantageous at least due the system's user-friendly, automatic, and / or integrated portioning capabilities, which may not be typically found in conventional portafilter-type coffee machines.

[0041] It will be understood that the present invention may encompass, but may not be limited to, the portioning means according to the embodiments described in the preceding two paragraphs. For example, in some embodiments, the portioning means may comprise a portioning means opening, configured to place the dose of grounds into the brewing chamber. In these embodiments, the brewing chamber may be comprised in the conveying assembly. The second opening may be essentially aligned with the filter, when the conveying assembly is in the first position. In the first position, the first opening may be essentially aligned with the stamp. The stamp may be configured to snug-fit, in the first position, into a stamp resting house. The stamp-resting housing may be comprised in the brewing compartment. The stamp-resting housing may be essentially aligned with the first opening, when the conveying assembly is in the first position. In the first position, a blocking element, comprised in the conveying assembly, may be configured to obstruct the portioning means opening. The conveying assembly may be configured to be moved reciprocally between the at least one first position and at least a third position. In the third position, the blocking element may be configured to leave the portioning opening free. In the third position, the first opening may be configured to be essentially aligned with the portioning opening. The second opening may be essentially aligned with the filter, when the conveying assembly is in the third position. In other words, the brewing chamber may move with the filter, when the conveying assembly moves between the first position and the third position. In the third position, the dose of grounds may fall, through the portioning opening and the first opening, into the brewing chamber.

[0042] The plunging mechanism may be configured to plunge the stamp into the brewing chamber towards the second opening, through the at least one second cover hole and through the at least one portioning hole, when the portioning disc is in the placing position. The dose of grounds may amount to between 1 g and 15 g, preferably between 2.5 g and 11 g, more preferably between 3.4 g and 7.1 g.

[0043] In some embodiments, the system may comprise a liquid supply means, configured to heat, pressurize, and dispense a portion of a liquid. For example, the liquid may comprise water. The liquid supply means may be electrically powered. The liquid supply means may further be connected to the stamp. The stamp may also be configured to supply the heated and pressurized portion of the liquid into the brewing chamber. The liquid supply means may be configured to force the heated and pressurized portion of the liquid through the brewing chamber, towards the second opening, and / or, when the conveying assembly is the first position, through the filter. The system may be configured to force the heated and pressurized portion of the liquid through the brewing chamber, towards the second opening, and / or, when the conveying assembly is the first position, through the filter. The temperature of the heated and pressurized portion of the liquid, preferably within the brewing chamber, may be in a range between 84 °C and 94 °C, preferably between 87 °C and 93 °C, more preferably between 90 °C and 92 °C. The pressure of the heated and pressurized portion of the liquid, preferably within the brewing chamber, may be in a range between 6.5 bar and 11.5 bar, preferably between 7.5 bar and 10.5 bar, more preferably between 8.5 bar and 9.5 bar. The liquid supply means may further comprise a pump. The portion of the liquid amounts to between 10 ml and 1 L, preferably 15 ml and 200 ml, more preferably 20 ml and 60 ml. The system may comprise a liquid portioning activation means. The liquid portioning activation means may be configured to be engaged by a user and / or to generate a liquid portioning input. The system may be configured to determine the portion of the liquid based on the liquid portioning input.

[0044] Embodiments of the present invention may be advantageous at least because the dose of grounds, e.g of coffee powder, may be pressed, the pressurized water supply may be supplied and the content of the brewing chamber, comprising e.g. used coffee grounds may be ejected, all via the centrally positioned main lever. The layout of the lever, and particularly of the stamp, may advantageously allow high contact pressure, i.e. tamping of the dose of grounds, which may be required for a correspondingly high coffee extraction. The preparation of the coffee grounds may determine the possible brewing pressure.

[0045] The locking mechanism, which may be defined by the plunging mechanism in the at least one locking position, may withstand the forces exerted during the brewing process. The locking mechanism may therefore advantageously be a safety-relevant component that releases the liquid supply means once it has engaged. For safety reasons, liquid supply means, comprising e.g. a pump, may be configured not to dispense before the hand lever is engaged in the at least one locking position.

[0046] In some embodiments the system may comprise a controller. The controller may be configured to control the liquid supply means. The controller may be configured to activate the liquid supply means after receiving a brewing input, particularly from a user.

[0047] The system may comprise an activation means, configured to be engaged by a user and / or to generate said brewing input. For example, said activation means may comprise a button.

[0048] In some embodiments, the system may comprise a liquid storing means. The liquid storing means may comprise a tank. The liquid storing means may be configured to store the liquid. The liquid supply means may be configured to draw the portion of the liquid from the liquid storing means.

[0049] Additionally, or alternatively, the system may comprise a grinder. The grinder may be configured to generate the grounds. The grinder may be configured to generate the grounds from coffee beans.

[0050] The system may comprise a grounds storing means. The grounds storing means may comprise a tank. The grounds storing means may be configured to receive the grounds from the grinder. The portioning means may be configured to receive the grounds stored in the grounds storing means.

[0051] In the receiving position, the portioning hole may be configured to receive the grounds, preferably through the at least one first cover hole, from the grounds storing means.

[0052] In some embodiments, the system may comprise a waste basket. The waste basket may be configured to receive the content of the brewing chamber, said content being pushed out of the brewing chamber by the plunging mechanism.

[0053] Embodiments of the present invention may be advantageous at least because the plunging mechanism comprises a single stamp, performing both the pressing and / or stamping of the dose of ground and the expelling of the content of the brewing chamber, e.g. used grounds, from the brewing chamber. Automatic machines may involve two moving plungers that work in opposite directions, i.e. both move towards the brewing center. The first plunger moves towards the center to press the grounds. The second plunger moves towards the center to eject the coffee grounds. According to embodiments of the present invention, the content of the brewing chamber, e.g used grounds, e.g. used coffee grounds, may ejected in the 'press' direction by shearing off the bottom of the brewing chamber, i.e. by moving the conveying assembly to the second position. This shearing may open the bottom of the brewing compartment and the stamp can be pushed completely through the brewing compartment, i.e. the plunging mechanism can be moved to the expelling position. When the base is sheared off, the waste basket may be positioned under the brewing compartment at the same time, by moving the conveying assembly to the second positions. The content of the brewing chamber, for example a coffee grounds puck, can therefore be ejected directly into the waste basket without any detours.

[0054] At least a part of at least one among the portioning means, the plunging mechanism, the brewing compartment, and the conveying assembly may be made of aluminum.

[0055] The volume of the system may be between 8000 cm3and 20000 cm3, preferably between 9000 cm3and 15000 cm3, more preferably between 10000 cm3and 13000 cm3.

[0056] The brewing compartment may comprise the brewing chamber and a rest of the brewing compartment. The rest of the brewing compartment may also be referred to as the brewing compartment other than the brewing chamber.

[0436] Detailed description of the figures

[0437] It is noted that not all the figures carry all reference signs. Instead, in some of the figures, some of the reference signs have been omitted for sake of brevity and simplicity of illustration.

[0438] Hereafter, exemplary embodiments of the present invention will be described in detail, referring to the accompanying figures.

[0439] First, a general overview of the system will be given, with reference to all the figures. It will be understood that embodiments of the present invention can also be directed to the corresponding methods.

[0440] The system can be a system for brewing a beverage, for example a hot beverage and / or coffee and / or, more specifically, espresso coffee. The system can be referred to, inter alia, as a coffee machine.

[0441] The system can comprise a brewing compartment 1, which can in turn comprise a brewing chamber 2. The system can further comprise a portioning means 3, a plunging mechanism 4, and a conveying assembly 5. Moreover, the system can comprise a grounds storing mean 6, a liquid storing means 7, and a liquid supply means 8.

[0442] More in detail, the grounds storing means 6 can be configured to store grounds. Grounds can be fine powder, for example fine coffee powder. The grounds storing means can comprise a tank for storing the grounds. It will be understood that the system can also comprise a grinder, which can be configured to generate the grounds, for example from beans. The grinder can generate, for instance, fine coffee powder from coffee beans, and can be provided with a storing means for the coffee beans. Furthermore, the grounds storing means 6 can be configured to receive the grounds from the grinder. The brewing chamber 2 can have cylindrical shape. The brewing chamber 2 can have a first opening 13 and a second opening 14. In particular, the first opening 13 may be configured to receive a dose of grounds, for example coffee grounds, while the second opening 14 may be configured to deliver a brewed beverage. The first opening 13 can be referred to as "top" opening and the second opening can be referred to as "bottom opening".

[0443] The portioning means 3 can be configured to receive grounds from the grounds storing means 6. The portioning means 3 can also be configured to portion the dose of grounds out of, i.e. from, the grounds and to place said dose of grounds into the brewing chamber 2, for example through the first opening 13. The portioning may be achieved by engaging a portioning lever 9.

[0444] The conveying assembly 5 is embedded in the system. In other words, during normal use, it may not be removed. In still other words, it may not be needed to remove the conveying assembly 5 or parts thereof at any point for the system to brew a beverage. The conveying assembly 5 can comprise a filter 10. The filter 10 can be coffee filter for preparing espresso coffee. The filter 10 can also have a cross section essentially matching the cross section of the brewing chamber 2 in correspondence with the second opening 14. The filter 10 can also be configured to receive and hold the dose of grounds from the portioning means 3 thorough the brewing chamber, when the conveying assembly 5 is in a first position.

[0445] The filter 10 may also be referred to as a sieve.

[0446] Embodiments of the present invention may be advantageous at least because the filter 10, and the conveying assembly 5, may not be removed from the system during normal operation. In prior-art, conventional portafilter-type coffee machines, instead, the portafilter may have to be handled by an experienced barista, attached and detached during normal operation of the conventional portafilter-type coffee machine in order to obtain, for example, good espresso coffee. Embodiments of the present invention may offer the advantage of delivering a good espresso coffee without the need for barista expertise and without the hassle of handling a portafilter, which has to be fixed to and removed from the conventional portafilter-type coffee machine in order to deliver good espresso coffee.

[0447] The conveying assembly 5 can be configured to be moved back and forth between the first position and a second position. In the first position, the filter 10, comprised in the conveying assembly, is essentially aligned with the second opening 14. In the second position, instead, the filter 10 is moved away from the second opening 14, so that the second opening 14 is left unobstructed. The conveying assembly 5 can comprise a conveying assembly activation means 68, which can, for example, be a handle. The reciprocal movement of the conveying assembly 5 between the first position and the second position can be continuous. Further, said movement can be activated by engaging the conveying assembly activation means 68.

[0448] The plunging mechanism 4 can comprise a stamp 11 and a main lever 12. The stamp 11 can be configured to snug-fit into the brewing chamber 2, like a piston. In other words, the stamp 11 can be moved back and forth into the brewing chamber 2. The main lever 12 and the stamp 11 can be configured to be coupled such that the movement of the stamp 11 within the brewing chamber 2 can be achieved by engaging the main lever 12.

[0449] The plunging mechanism 4 can be configured to be moved reciprocally between a plurality of positions. In particular, for example, between at least a rest position, a locking position, and an expelling position. Said movement be achieved by engaging the main lever 12.

[0450] In the rest position, the stamp 11 can be configured to occupy a volume of the brewing chamber that is adjacent to the first opening 13, so that the portioning means 3 is allowed to place grounds into the brewing chamber 2.

[0451] In the locking position, the plunging mechanism is configured to plunge the stamp 11 into the brewing chamber 2 towards the second opening 14. It will be understood that the locking position can be preferably achieved if the conveying assembly 5 is in the first position. In fact, in this case, the plunging mechanism 4 can tamp, via the stamp 11, the dose of grounds that is held by the filter 10. Moreover, the plunging mechanism 4 can close, in a pressure-tight manner, the brewing chamber 2. In other words, the second opening 14 can be closed by the filter 10, when the conveying assembly 5 is in the first position, and the first opening 13 can be closed by the stamp 11, when the plunging mechanism is in the locking position.

[0452] In the expelling position, the plunging mechanism is configured to plunge the stamp 11 into the brewing chamber 2 towards the second opening even further than in the locking position. It will be understood that the expelling position can be preferably achieved if the conveying assembly 5 is in the second position. In this case, in fact, the plunging mechanism 4 can push contents of the brewing chamber 2 out of the brewing chamber, through the second opening 14. The liquid storing means 7 can comprise a tank for storing a liquid. The liquid can comprise water. The liquid supply means 8 can be configured to heat, pressurize, and dispense a portion of the liquid. In particular, the liquid supply means 8 can be configured to draw the portion of the liquid from the liquid storing means 7. The liquid supply means 8 can, for example, comprise a pump and be electrically powered. Furthermore, the liquid supply means 8 can be connected to the stamp 11, for example via a tube 15. The tube 15 may be a hose, such as a supply hose. The connection of the supply means 8 to the stamp 11 may be achieved via a stamp connection piece, which may further allow to attach and / or detach the tube 15. A hole provided through the stamp 11 may deliver the heated and pressurized portion of the liquid into the brewing chamber 2. In particular, it may provide the heated and pressurized portion of the liquid, such as water, to the "shower" sieve. A cavity in front of the sieve may distribute the water evenly over the sieve. A return valve, which may be located in the hole provided through the stamp 11, may prevent the heated and pressurized portion of the liquid from running back. Therefore, the stamp 11 can be configured to supply the heated and pressurized portion of the liquid into the brewing chamber 2. The liquid supply means 8 can be configured, for example via a pump, to force the heated and pressurized portion of the liquid through the brewing chamber 2, towards the second opening 14, and, when the conveying assembly is the first position, through the filter 10.

[0453] The system can further comprise a controller, configured to control the liquid supply means 8, and an activation means 16. The activation means can be a button and can be configured to be engaged to generate a brewing input. The controller is configured to activate the liquid supply means 8 after receiving said brewing input. In other words, for example, a user may engage the activation means 16 and, as consequence, the controller may drive the liquid supply means 8 to draw the portion of the liquid, to heat, pressurize the portion of the liquid and to force the portion of the liquid through the brewing chamber 2, towards the second opening 14.

[0454] Fig. 1 depicts, as an example, a system according to embodiments of the present invention, wherein the system is in four states.

[0455] In I, the plunging mechanism 4 can be in the rest position and the conveying assembly 5 can be in the first position. In II, the plunging mechanism 4 can be in the locking position and the conveying assembly 5 can be in the first position. In III, the plunging mechanism 4 can be in the locking position and the conveying assembly 5 can be in the second position. In IV, the plunging mechanism 4 can be in the expelling position and the conveying assembly 5 can be in the second position. The method according to embodiments of the present invention may comprise switching the system, at least one time, from at least one state to at least another state among I, II, III, and IV. For example, the system can be switched from I to II, and then to III, and then to IV. In doing so, a beverage, such as coffee and / or espresso coffee can be produced by the system.

[0456] More in detail, in I, the portioning means 3 can place a dose of grounds into the brewing chamber 2. This can be achieved by engaging the portioning lever 9, for example by pulling the portioning lever 9 (see arrow 22). The portioning lever 9 can, for instance, be pulled two or three times, depending, inter alia, on the amount of ground the dose of grounds is supposed to contain.

[0457] The system may further comprise a vibration component, configured to generate at least a vibrating signal. The vibrating signal is configured to enable the dose of grounds to be subject to a vibration, preferably after the dose of ground has been placed into the brewing chamber 2. In this case, the dose of ground may preferably rest on the filter 10.

[0458] The vibrating signal is configured to enable the brewing chamber 2 and / or the filter 10 to vibrate.

[0459] In II, the plunging mechanism 4 can tamp the dose of grounds in the brewing chamber 2, and close, in a pressure-tight manner, the brewing chamber 2. This can be achieved by engaging the main lever 12, for example by pulling the main lever down (see arrow 17). Further, the liquid the liquid supply means 8 can be activated by engaging the activation means 16, for example by pressing the activation means 16, which can be a button (see arrow 18). This can cause a portion of liquid to be heated, pressurized and forced through the brewing chamber 2 by the liquid supply means 8. In particular, the stamp 11 supplies the portion of liquid into the brewing chamber 2. The stamp 11 can be connected to the liquid supply means 8 and therefore to the liquid storing means 7. The plunging mechanism 4, and in particular the stamp 11, can therefore perform at least two tasks, i.e. pressing the grounds, in other words tamping, and supplying a heated and pressurized portion of a liquid, for example water. Overall, the system can, therefore, achieve the brewing of a beverage, said beverage being delivered by the second opening 14, through the filter 10.

[0460] In III, the brewing chamber 2 can be opened, in correspondence to the second opening 14. This can be achieved by engaging the conveying assembly activation means 68, which can, for example, be a handle. To this aim, the handle may be pulled (see arrow 19). Put differently, the brewing chamber 2 can be opened, at the bottom end of the brewing chamber 3, by pulling out a slider 20.

[0461] In IV, the plunging mechanism 4 can expel contents of the brewing chamber 2, through the second opening 14. This can be achieved by engaging the main lever 12, for example by pulling the main lever further down than in II and / or in III (see arrow 21). Put differently, for example, the system can be configured to eject contents of the brewing chamber, for example used coffee grounds, by pulling the main lever down all the way through.

[0462] Fig. 2 depicts, as an example, a plunging mechanism 4 according to embodiments of the present invention. The plunging mechanism 4 can comprise a main lever 12, a main cylinder 23, a connecting element 24, and a stamp 11.

[0463] Fig. 3 depicts, as an example, an exploded view of a plunging mechanism 4 according to embodiments of the present invention. The plunging mechanism can comprise a central pin handle 24, at least a locking pin 25 (here two), a locking spring 26, a central pin of the main cylinder 27, at least a clamping element 28 (here two), at least an unlocking means 30 (here two), at least an unlocking spring 29 (here two).

[0464] The at least one clamping element 28 can comprise at least a slotted hole 32. The at least one clamping element 28 may be a screw-on jaw. The at least one locking pin 25 may engage the at least one slotted hole 32 to lock the plunging mechanism 4. The exact position of the at least one slotted hole 32 may define when the at least one locking pin 25 locks into position.

[0465] The connecting element 24 is configured to couple the main lever 12 and the stamp 11 such that, when the main lever 12 is engaged, the stamp 11 moves within the brewing chamber 2. For example, if the main lever 12 is pulled down, e.g. by a user, the stamp 11 moves down, or in other words is plunged towards the second opening 14, into the brewing chamber 12. Vice versa, if the main lever 12 is pulled up, e.g. by a user, the stamp 11 moves up, towards the first opening 13, in the brewing chamber 2.

[0466] The central pin handle 24 is configured to couple the main lever 12 and the main cylinder 23 such that, when the main lever 12 is engaged, the main cylinder 23 rotates about the axis of the main cylinder 23. In other words, engaging the main lever 12 has the effect that the main cylinder 23 rotates about its axis and that the stamp 11 moves within the brewing chamber. At least a hole 33 (here two) can be provided along an axial direction of the main cylinder on at least one of the bases of the main cylinder 23. The holes 33 can be non-centered, i.e. they may not extend along the axis of the main cylinder 23, but along another axial direction. The holes 33 can be communicating, i.e. form a single hole running from one base to the other base of the main cylinder 23. The locking spring 26 may be positioned within holes 33. The locking pins 25 are configured to be snug-fit, like a piston, into the holes 33. In particular, the locking pins 25 are configured to be biased by the locking spring 26 to stick out of the holes 33.

[0467] The clamping elements 28 may be screw-on jaws. The clamping elements 28 can be coupled to the bases of the main cylinder 23 via the central pin of the main cylinder 27. When the main cylinder 23 rotates, the clamping elements 28 can be configured essentially stationary. The clamping elements 28, in particular, are configured to fit closely with the bases of the main cylinder 23, without preventing the rotation of the main cylinder 23. The clamping elements 28 can have slotted holes 32.

[0468] The stamp 11 may comprise a sealing ring groove 31, configured to receive a seating ring. This may be useful in pressure sealing the brewing chamber 2.

[0469] Fig. 4 A depicts, as an example, a perspective view and a side view of a plunging mechanism 4 in the rest position according to embodiments of the present invention.

[0470] In the rest position, the clamping elements 28 are configured to push the locking pins 25, by acting against the bias provided by the locking spring 26, into the holes 33. In the rest position, in other words, the locking pins 25 may not be aligned with the slotted holes 32 and the clamping elements 28, fitting closely with the bases of the main cylinder 23, may push the locking pins 25 into the holes 33.

[0471] As the plunging mechanism 4 moves from the rest position to the locking position, and as the cylinder 23 rotates, the locking pins 25 may come closer to being aligned with the slotted holes 32. The locking pins 25 may, however, still be pushed into the holes 33.

[0472] Fig. 4 B depicts, as an example, a perspective view and a side view of a plunging mechanism 4 in the locking position according to embodiments of the present invention.

[0473] In the locking position, the locking pins 25 may be allowed to stick out of the holes 33 and engage a first terminal portion 34 of the slotted holes 32. In the locking position, the locking pins 25 may be essentially aligned with the first terminal portion 34 of the slotted holes 32, so that the locking pins 25, under the bias of the locking spring 26 and without the impediment of the clamping elements 28, can stick out of the holes 33 and engage the first terminal portion 34 of the slotted holes 32.

[0474] Embodiments of the present invention may be advantageous at least because the tamping of, for example, coffee grounds may be executed in a manner that does not require, for instance, barista expertise. By simply moving the plunging mechanism 4 in the locking position, optimal tamping may be achieved.

[0475] In prior-art portafilter-type coffee machines, instead, the tamping may not be performed in a user-friendly and automatic manner. Embodiments of the present invention may guarantee the good espresso quality of a portafilter-type coffee machine, without relying on tamping expertise of a skilled barista.

[0476] In the expelling position, the locking pins 25 may be allowed to stick out of the holes 33 and engage a second terminal portion 35 of the slotted holes 32. In the expelling position, the locking pins 25 may be essentially aligned with the second terminal portion 35 of the slotted holes 32, so that the locking pins 25, under the bias of the locking spring 26 and without the impediment of the clamping elements 28, can stick out of the holes 33 and engage the second terminal portion 35 of the slotted holes 32.

[0477] In moving the plunging mechanism 4 from the locking position to the expelling position, the locking pins 25 may essentially continuously engage the slotted holes 32, or in other words slide within the slotted holes 32, and move from the first terminal portion 34 to the second terminal portion 35.

[0478] Embodiments of the present invention may be advantageous at least because, for example, used coffee grounds may be expelled from the system in a fast and efficient manner. By simply moving the plunging mechanism 4 in the expelling position, used coffee grounds may be expelled and the brewing chamber 2 may therefore be easily cleaned.

[0479] In prior-art portafilter-type coffee machines, instead, the cleaning may require detaching the portafilter, which may lead to used coffee grounds being spread over the space surrounding the portafilter-type coffee machine or, in general, to an increased involvement of the user in cleaning. Embodiments of the present invention may guarantee an easy, fast and efficient way of cleaning the system after a beverage has been brewed. The position of the slotted hole 32 on one clamping element 28, coupled to one base of the main cylinder 23, may be different than the position of the slotted hole 32 on the other clamping element 28, coupled on the other base of the main cylinder 23. This may allow to achieve two locking positions. In other words, two levels of tamping may be achieved, depending for example on the amount of grounds that may be present in the brewing chamber 2. It will be understood that several other levels of tamping may be achieved by utilizing more than two slotted holes 32.

[0480] In order to move the plunging mechanism 4 from a position in which at least one of the locking pins 25 engages at least one of the slotted holes 32, for example the locking position or the expelling position, to a position in which at least one of the locking pins 25 does not engage at least one of the slotted holes 32, for example the resting position, the unlocking means 30 can be engaged. The unlocking means 30 may, for example, comprise unlocking buttons. The unlocking means 30 may be coupled to the clamping elements 28 such the when the unlocking means 30 are engaged, if at least one of the locking pins 25 is engaged to any portion of at least one of the slotted holes 32, the least one of the locking pins 25 is pushed into its corresponding hole 33. The pushing may be achieved via the unlocking spring 29. The engaging of the unlocking means 30 may be achieved, for example, by pressing.

[0481] In summary, coffee grounds may be pressed, or tamped, and ejected by pulling the main lever 12 in the same direction, i.e. by pulling downwards. The main cylinder 23 may be rotated by pulling the main lever 12. Inside the main cylinder 23 there may be a noncentered hole 33 in the axial direction into which two locking pins 25 and a locking spring 26 may be inserted. The locking pins 25 may be automatically pushed out by the locking spring 26 force when the locking pins 25 reach the locking area (i.e. the first terminal portion 34 of the slotted holes 32) of the clamping elements 28, which may be screw-on jaws (slotted hole). The unlocking means 30, which may comprise release buttons, may only be required to return the main lever 12 to its original position, i.e. to the rest position. The release buttons may be the counterpart to the locking area of the screw-on jaw. By pressing the release buttons, the locking pins 25 can be pushed all the way in and the main cylinder returned to its original position. There may be two staggered locking positions (left and right), one that may lock earlier and one that may lock a second time later. This may allow two different filling levels of coffee grounds (small or large coffee).

[0482] Fig. 5 A depicts, as an example, a part of the system according to embodiments of the present invention. Fig. 5 B depicts, as an example, exploded views of a part of the system according to embodiments of the present invention.

[0483] The peripheral region of the second opening 14 can comprises rails 38, configured to engage rail grooves 39.

[0484] The conveying assembly 5 can comprise a slider 20. The slider may comprise a filter carrier 37, configured to hold the filter 10. Furthermore, the slider can comprise the rail grooves 39. The conveying assembly can be configured to be moved between the first position and the second position by sliding the slider 20 along the rails 38.

[0485] It will be understood that, according to embodiments of the present invention, the conveying assembly can be configured to be moved between the first position and the second position by other mechanisms other than sliding.

[0486] The peripheral region of the second opening 14 can comprise a sealing ring groove 54, configured to receive a seating ring for establishing a pressure-tight sealing of the brewing chamber, when the conveying assembly 5 is in the first position and the plunging mechanism 4 is in the locking position.

[0487] Fig. 6 A depicts, as an example, a part of the system, wherein the conveying assembly 5 is in a first position, according to embodiments of the present invention.

[0488] Fig. 6 B depicts, as an example, a part of the system, wherein the conveying assembly 5 is in a second position, according to embodiments of the present invention.

[0489] The system, particularly the conveying assembly 5, can comprise a waste basket 40. The waste basket 40 can be configured to receive the content of the brewing chamber 2, said content being pushed out of the brewing chamber 2 by the plunging mechanism 4.

[0490] When the conveying assembly 5 is in the second position, an opening of the waste basket 40 may be aligned with the second opening 14. If the plunging mechanism 4 is, concurrently, in the expelling position, the content of the brewing chamber 2 can be received by the waste basket 40.

[0491] In summary, the conveying assembly 5 can be moved back and forth between two positions. The first position may be the starting position and may represent the closed and / or sealed brewing chamber 2. In the second position, the slider 20 and the connected filter holder carrier 37, which may be referred to as coffee grounds container, may be pulled out at the same time. The base of the brewing chamber 2 is thus sheared off and the brewing chamber 2 is open at the bottom, that is at the second opening 14. The coffee grounds can be ejected downwards using the main lever 12 and the connected stamp 11. After cleaning the brewing chamber 2, the conveying assembly 5 can be returned to its original position, i.e. to the first position.

[0492] When compared to prior-art portafilter-type coffee machines, embodiments of the present invention may be adventitious at least because the cleaning can be performed in an easy, fast, and / or efficient manner. According to embodiments of the present invention, for example, there might be no need of pulling out a portafilter or a filter in order to clean, which may make the cleaning process faster and easier.

[0493] Fig. 7 depicts, as an example, an exploded view of a portioning means 3 and of a brewing compartment 1 according to embodiments of the present invention.

[0494] The portioning means can comprise a portioning lever 9, a portioning spring 41, a drive tooth 42, a gear wheel 43, connection pins 44, a cover 36, a portioning disc 45 and a central axis 49.

[0495] The gear wheel 43 may be a freewheel, i.e. allow for rotation in only one direction, thanks to the connection pins 44.

[0496] The portioning lever 9 may be coupled, via the gear wheel 43, to the portioning disc 45, such that, by engaging the portioning lever 9, the portioning disc 45 can rotate about the axis of the portioning disc 45. The portioning disc 45 is configured to snug-fit into the cover 36.

[0497] The portioning disc 45 can comprise at least a portioning hole 48 (here four). The portioning holes 48 may be cylindrical and may be directly adjacent to inner surfaces of the cover 36. In other words, the portioning holes 48 can be configured to fit closely with inner surface of the cover 36. The cover may have a first cover hole 46 and a second cover hole 47.

[0498] The portioning disc 45 can be configured to rotate cyclically between at least a receiving position and a placing position. In the receiving position, at least one portion hole 48 is configured to receive the dose of grounds, preferably through the at least one first cover hole 46. In moving from the receiving position to the placing position, the at least one portioning hole 48 can be configured to portion the dose of the grounds by moving away from the at least one first cover hole. This may happen since the portioning disc 45 may fit closely with the cover 36. Therefore, in the receiving position, the at least one portioning hole 48 can be filled with the dose of grounds and, by moving to the placing position, shear off the dose of grounds from the grounds. In the placing position, the at least one portioning hole 48 can be configured to place the dose of grounds into the brewing chamber 2, preferably by letting the dose of grounds fall into the brewing chamber, through the first opening 13. The plunging mechanism 4 may then stamp the grounds that are placed in the brewing chamber.

[0499] It will be understood that, when more than one portioning hole 48 is present, the receiving position and the placing position of the portioning disc 45 with respect to one portioning hole 38 may be different from the receiving position and the placing position of the portioning disc 45 with respect to another portioning hole 38.

[0500] Fig. 8 depicts, as an example, a portioning means 3 and of a brewing compartment 1 according to embodiments of the present invention, wherein the portioning means 3 is in four stages.

[0501] The four stages T, IT, III', IV' may be sequential in time.

[0502] In T, the portioning disc 45 can be in the receiving position with respect to portioning hole 48'. Portioning hole 48' can receive and be filled with the dose of grounds through the first cover hole 46 (see arrow 50).

[0503] In IT, the portioning lever 12 can have been engaged and the portioning disc 45 can have been accordingly rotated of 45 degrees with respect to the portioning disc in I'. Portioning hole 48' can portion the dose of grounds by shearing off the dose of grounds from the grounds.

[0504] In III', the portioning lever 12 can have been engaged and the portioning disc 45 can have been accordingly rotated of 45 degrees with respect to the portioning disc in IT, in other words of 90 degrees with respect to the portioning disc in T.

[0505] In IV', it is shown how the portioning lever 12 may be engaged and brought back to the position the portioning lever 12 had in T (see arrow 53). Since the gear wheel 43 may be a freewheel, said bringing back may not involve any rotation of the portioning disc 45. Therefore, the position of portioning hole 48', and of the other portioning holes 48", 48'", and 48"" may be unchanged as compared to III'. Starting from IV', by engaging the portioning lever 12 and by rotating the portioning disc 45 of 90° with respect to the portioning disc in IV', the portioning disc may reach may reach the placing position with respect to portioning hole 48', and place the dose of grounds into the brewing chamber 2. Said engaging may involve performing the movement of the portioning lever indicated by arrows 51 and 52, again. This is not shown in the figures.

[0506] Essentially, starting from the position of the portioning lever 12 in T, (i) engaging the portioning lever 12 to perform a 90 degrees rotation of the partitioning disc 45 as described by arrows 51 and 52, (ii) engaging the portioning lever 12 as indicated by arrow 53, and (iii) engaging the portioning lever 12 to perform a 90 degrees rotation of the partitioning disc 45 as described by arrows 51 and 52 another time, the portioning of the dose of grounds and the placing of the dose of ground into the brewing chamber can be obtained with portioning hole 48'. It will be understood that this can be obtained by any of portioning holes 48", 48'", and 48"" as well. For example, in I' the portioning disc 45 is in the placing position for portioning hole 48'", and in III' the portioning disc 45 is in the receiving position for portioning hole 48"".

[0507] A method according to embodiments of the present invention may include operating the portioning means 3 as described in this specification.

[0508] In summary, portioning can be carried out using the portioning lever 12. The portioning lever 12 may connected to the portioning disc 45 via a freewheel, which only allows the driving force to be applied in, e.g., a clockwise direction, via the connection pins 45. The portioning disc 45 may have at least a portioning hole 48, for example four portioning holes 48', 48", 48'", and 48"", which may have essentially the diameter of the brewing chamber, so that the stamp 11 can pass through them. If the portioning lever 12 is turned 90 degrees clockwise, the portioning disc may also be turned 90 degrees. One portioning hole, e.g. portioning hole 48', can pass through the coffee insert, i.e. the correspondence with the first cover hole 46, can shear off the needed dose of coffee grounds and can hold the needed dose of coffee grounds in place. As soon as the portioning disc 45 is further turned to reach the placing position for portioning hole 48', the coffee powder may fall into the brewing compartment. The portioning lever 12 can be reset simply by returning the portioning lever 12 to the starting position. The freewheel can prevent the portioning disc 45 from turning back. Embodiments of the present invention may be advantageous at least because of the user- friendly, automatic, and / or embedded portioning capabilities of the system. This may not be the case for conventional portafilter-type coffee machine.

[0509] Fig. 9 depicts, as an example, a system according to embodiments of the present invention, wherein the system is in four other states. It will be understood that the present invention may encompass, but may not be limited to, the portioning means 3 according to the embodiments described so far in the figure description. Fig. 9 depicts exemplary embodiments relating thereto. For example, in some embodiments, the portioning means 3' may comprise a portioning means opening 55, configured to place the dose of grounds into the brewing chamber 2. In these embodiments, the brewing chamber 2 may be comprised in the conveying assembly 5. In simple words, the brewing chamber 2 may be releasably coupled to the brewing compartment 1 and the brewing chamber 2 may move, together with the conveying assembly 5 and relative to the rest of the system, in one or more positions of the conveying assembly 5. In particular, the brewing chamber may move, together with the conveying assembly and relative to the rest of the system, between the first position and a third position. The brewing chamber 2 may also be releasably coupled to the conveying assembly 5. In fact, the conveying assembly 5 may move, relative to the rest of the system (including the brewing chamber 2), between the first position and the second position. Put differently, starting from the first position: (i) the conveying assembly 5 may move to the third position together with the brewing chamber 2 (released coupling between the brewing chamber 2 and the rest of the brewing compartment 1), and (ii) the conveying assembly 5 may move to the second position while the brewing chamber 2 does not move (released coupling between the brewing chamber 2 and the conveying assembly 5).

[0510] The rails 38 on the peripheral region of the second opening 14 and the rail grooves 39 of the conveying assembly may allow movement of the conveying assembly between the first position and the second position. Analogously, the peripheral region of the first opening 13 may comprise second rails and corresponding second rail grooves 63 may be provided on the brewing compartment 1, particularly on the bottom of the brewing compartment 1. The second rails and the second rail grooves 63 allow movement of the conveying assembly, together with the brewing chamber 2, between the first position and the third position. It will be understood that, according to embodiments of the present invention, the conveying assembly can be configured to be moved between the first position and the second position, and between the first position and the third position, by other mechanisms other than sliding. The second opening 14 may be essentially aligned with the filter 10, when the conveying assembly 5 is in the first position. In the first position, the first opening 13 may be essentially aligned with the stamp 11. The stamp 11 may be configured to snug-fit, in the first position, into a stamp resting house 56. The stamp-resting housing 56 may be comprised in the brewing compartment 1. The stamp-resting housing 56 may be essentially aligned with the first opening 13, when the conveying assembly 5 is in the first position. In the first position, a blocking element 57, comprised in the conveying assembly 5, may be configured to obstruct the portioning means opening 55.

[0511] The conveying assembly 5 may be configured to be moved reciprocally between the at least one first position and at least a third position. In the third position, the blocking element 57 may be configured to leave the portioning opening 55 free. In the third position, the first opening 13 may be configured to be essentially aligned with the portioning opening 55. The second opening 14 may be essentially aligned with the filter 10, when the conveying assembly 5 is in the third position. In other words, the brewing chamber 2 may move with the filter 10, when the conveying assembly 5 moves between the first position and the third position. It will be understood that the blocking element 57, comprised in the conveying assembly, may move together with the conveying assembly 5. In the third position, the dose of grounds may fall, through the portioning opening 55 and the first opening 13, into the brewing chamber 2.

[0512] The conveying assembly 5 may be configured to be moved reciprocally between the at least one first position and the at least one second position. In the second position, an opening of the waste basket 40 may be aligned with the second opening 14. In the second position, the conveying assembly 5, particularly the slider 20 and the connected filter holder carrier 37, which may be referred to as coffee grounds container, may be pulled out at the same time. The brewing chamber 2, instead, may not move when the conveying assembly moves from the first to the second position. The base of the brewing chamber 2 is thus sheared off and the brewing chamber 2 is open at the bottom, that is at the second opening 14. The coffee grounds can be ejected downwards using the main lever 12 and the connected stamp 11. After cleaning the brewing chamber 2, the conveying assembly 5 can be returned to its original position, i.e. to the first position.

[0513] In I", the plunging mechanism 4 can be in the rest position and the conveying assembly 5 can be in the first position. In II", the plunging mechanism 4 can be in the resting position and the conveying assembly 5 can be in the third position. In III", the plunging mechanism 4 can be in the locking position and the conveying assembly 5 can be in the first position. In IV, the plunging mechanism 4 can be in the expelling position and the conveying assembly 5 can be in the second position. The method according to embodiments of the present invention may comprise switching the system, at least one time, from at least one state to at least another state among I", II", III", and IV". For example, the system can be switched from I" to II", and then to III", and then to IV". In doing so, a beverage, such as coffee and / or espresso coffee can be produced by the system.

[0514] More in detail, in II", the portioning means 3' can place a dose of grounds into the brewing chamber 2. This can be achieved by moving the conveying assembly 5 from the first position to the third position (see arrow 58). In III", the conveying assembly 5 may be brought to the first position (see arrow) 59. In III", The plunging mechanism 4 can tamp the dose of grounds in the brewing chamber 2, and close, in a pressure-tight manner, the brewing chamber 2. This can be achieved by engaging the main lever 12, for example by pulling the main lever down (see arrow 60). Further, the liquid the liquid supply means 8 can be activated by engaging the activation means 16, for example by pressing the activation means 16, which can be a button (see arrow 18). This can cause a portion of liquid to be heated, pressurized and forced through the brewing chamber 2 by the liquid supply means 8. In particular, the stamp 11 supplies the portion of liquid into the brewing chamber 2. The stamp 11 can be connected to the liquid supply means 8 and therefore to the liquid storing means 7. The plunging mechanism 4, and in particular the stamp 11, can therefore perform at least two tasks, i.e. pressing the grounds, in other words tamping, and supplying a heated and pressurized portion of a liquid, for example water. Overall, the system can, therefore, achieve the brewing of a beverage, said beverage being delivered by the second opening 14, through the filter 10. In IV", the brewing chamber 2 can be opened, in correspondence to the second opening 14. This can be achieved by moving the conveying assembly 5 from the first to the second position (see arrow 61). In IV", the plunging mechanism 4 can expel contents of the brewing chamber 2, through the second opening 14. This can be achieved by engaging the main lever 12, for example by pulling the main lever further down than in III" (see arrow 62). Put differently, for example, the system can be configured to eject contents of the brewing chamber, for example used coffee grounds, by pulling the main lever down all the way through.

[0515] The system may be equipped with releasable locking means for the conveying assembly 5. The releasable locking means may be configured to lock, in a releasable manner, the conveying assembly 5 and the brewing chamber 2 in their respective locations in the first, second, and third position. Below, this will be described with general reference to Figs. 10, 11, 12, and 13. The releasable locking mechanism may comprise a first spring loaded pin 64 and a second spring loaded pin 66. The first spring loaded pin 64 may be provided in the brewing compartment. Particularly, the first spring loaded pin 64 may stick out therefrom and be housed in, when its spring is extended and non-engaged, in a corresponding first pin housing 65. The first pin housing 65 may be provided, e.g. as a hole, on the brewing chamber 2 or on a piece integral to the brewing chamber 2. The second spring loaded pin 66 may be provided in the brewing chamber 2 or in a piece integral to the brewing chamber 2. Particularly, the second spring loaded pin 66 may stick out therefrom and be housed in, when its spring is extended and non-engaged, in a corresponding second pin housing 67. The second pin housing 67 may be provided, e.g. as a hole, on the conveying assembly 5. In simple words, the first spring loaded pin 64 may lock, when its spring is extended and non-engaged, the brewing chamber 2 to the rest of the brewing compartment. This may happen in the first position, in the second position, and in the movement between said first and second position. Analogously, the second spring loaded pin 66 may lock, when its spring is extended and non-engaged, the brewing chamber 2 to the conveying assembly 5. This may happen in the first position, in the third position, and in the movement between said first and third position. The first spring loaded pin 64 and corresponding housing 65 may be provided on a first side of the system, while the second spring loaded pin 66 and corresponding housing 67 may be provided on a second side of the system, opposite to the first side. It will be understood that the releasable coupling between the brewing chamber 2 to the rest of the brewing compartment 1 and the conveying assembly 5 may be realized, in some exemplary embodiments, via the first spring loaded pin 64 and via the second spring loaded pin 66, respectively. Examples of how the releasable coupling between the brewing chamber 2 to the rest of the brewing compartment 1 and the conveying assembly 5 will be discussed in the following.

[0516] The movement of the conveying assembly in the first, second, and third position may be achieved by engaging the conveying assembly activation means 68, which may exemplarily be a handle 68. The releasable coupling between the brewing chamber 2 to the rest of the brewing compartment 1 and the conveying assembly 5 may also be operated via the handle 68.

[0517] The handle 68 may be integral with the conveying assembly 5 and rigid. The movement of the conveying assembly 5 and / or of the brewing chamber 2 in the first, second, third position may essentially be a longitudinal movement along a longitudinal axis, as e.g. indicated by the arrows 58, 59, and 61. The conveying assembly may further be configured to rotate around a rotation axis 69, essentially perpendicular to the longitudinal axis of the conveying assembly 5 and to the direction that the plunger 11 may move along. The rotation axis 69 may define a fulcrum of the conveying assembly for the rotation of the conveying assembly 5 around the rotation axis 69. The conveying assembly may therefore comprise a first arm and a second arm of the conveying assembly 5, said arms extending in opposite direction from the fulcrum of the conveying assembly along a longitudinal axis of the conveying assembly. The rotation may be achieved by engaging the handle 68, particularly by either pushing the handle 11 down (see arrow 74) or by pulling it up (see arrow 75). A terminal portion of the conveying assembly 5, said terminal portion being opposite to the handle 68, may be provided with a first protruding tab 72 and a second protruding tab 73. The first protruding tab 72, in particular, may be provided on the first arm of the conveying assembly 5 and the second protruding tab 73 may be provided on the second arm of the conveying assembly 5. The first protruding tab 72 may be provided on the first side of the system, while the second protruding tab 73 may be provided on the second side of the system, opposite to the first side.

[0518] By engaging the handle 68 and rotating the conveying assembly 5 in a first rotation direction around the rotation axis 69 (e.g. by "pushing down", see arrow 74), the first protruding tab 72 may push the first spring loaded 64 and free the first housing 65, thus releasing the coupling between the brewing chamber 2 and the rest of the brewing compartment 1 and allowing the movement of the conveying assembly 5, along with the brewing chamber 2, from the first position to the third position (see arrow 58) and vice versa (see arrow 59). By engaging the handle 68 and rotating the conveying assembly 5 in a second rotation direction around the rotation axis 69 (e.g. by "pulling down", see arrow 75), the second protruding tab 73 may push the second spring loaded 66 and free the second housing 67, thus releasing the coupling between the brewing chamber 2 and the conveying assembly 5, and allowing the movement of the conveying assembly 5 from the first position to the second position (see arrow 61). Simply put, the handle 68 may be in a neutral position 76, in a first rotated position 77 and in a second rotated position 78, wherein the first rotated position 77 may be defined by the first rotation and the second rotated position 78 may be defined by the second rotation.

[0519] Fig. 10 depicts, as an example, a system according to embodiments of the present invention, wherein the conveying assembly activation means 68, here a handle 68, is in the neutral position 76, in the first rotated position 77 and in the second rotated position 78.
