Technical Field

The field of the invention relates to beverage preparation machines provided with a specific extraction arrangement, for example machines using capsules in which ingredients to be prepared a beverage are contained.

For the purposes of this specification, "beverage" is intended to include any liquid substance that is edible to humans, such as tea, coffee, hot or cold chocolate drink, milk, soup, baby food, and the like. "capsule" is intended to include any kind of pre-portioned beverage ingredient, such as a flavouring ingredient, placed in a closed package, in particular an airtight package, made of any kind of material (e.g. plastic, aluminium, recyclable and/or biodegradable packages) and which may be of any shape and configuration, including a soft pod or a rigid cartridge containing said ingredient. The capsule may contain a quantity of ingredients for preparing a single-serving beverage or multiple-serving beverage.

Background

It is well known to prepare beverages by extracting an extractable ingredient, such as a brewable ingredient, e.g. roast and ground coffee and/or tea, in particular an extractable ingredient contained in a serving container such as a capsule, a portion pack or a sachet.

EP0512468 relates to capsules having a cup-shaped body and a tearable beverage outlet membrane. This film is typically a thin aluminium film which tears against a tear-open extraction panel of the beverage extraction device, such as described in EP 0512470.

EP0512470 relates to a system for extracting coffee using a beverage extraction unit with a tear-open extraction plate comprising a plurality of raised elements and channels therebetween (called "flow grid and embossed surface elements") adapted to receive a sealed capsule to introduce water under pressure into the capsule via a water injector, deform an outlet membrane or cover (e.g. an aluminium membrane) and tear it under the pressure of the liquid rising in the capsule to allow the beverage to be released from the capsule.

EP0602203 relates to a sealed flexible pouch, in the form of a separate portion suitable for extraction under pressure, containing at least one powdery substance for the preparation of a beverage, such as roast and ground coffee; the pouch comprises two identical flexible sheets of circular, elliptical or polygonal shape, which provide space for the substance between each other and are sealed on their periphery such that the pouch is substantially symmetrical with respect to its sealing plane, the pouch being opened under the effect of the pressure increase in the pouch when the extraction liquid is injected.

EP0870457 relates to an extraction unit similar to EP0512470, but adapted for a closed impermeable pouch containing a coffee substance such as described in EP 0602203. The device includes: an upper member comprising means for perforating an upper surface of the pouch and allowing water to be introduced into the pouch; a lower member having a receptacle for receiving a capsule and a raised portion and a hollow portion; wherein the extraction surface of the pouch is gradually and locally pulled against the raised portion and the hollow portion; in order to make the liquid flow after extraction, the extraction surface tears open at a plurality of locations according to a path predetermined by the positions of the raised portions and the hollow portions and reaches its breaking tension there. The lower portion typically includes flow apertures that allow beverage to flow therethrough. The raised portions and hollow portions are preferably in the form of truncated pyramids separated by a network of channels.

Thus, a convenient prior art beverage extraction system utilizes a replaceable capsule (e.g., a rigid capsule, a pouch, or a flexible dosing bag) that includes a tearable beverage outlet membrane (e.g., a thin aluminum foil) that can only be torn when the membrane is sufficiently deformed against the raised elements of the tear-away plate. Tearing typically occurs at the edges of the raised elements, which are typically a plurality of small truncated pyramids or linear ridges. The tearing results in the formation of small holes along the edges of the raised elements. These apertures are relatively small (e.g., 0.1mm to 1.0mm long and 0.1mm to 0.3mm wide) and typically the exit film at least partially conforms to the top and upper sides of the raised elements, further reducing the flow opening area. Therefore, the pressure drop at this interface is relatively high. Furthermore, the filtering of the coffee particles takes place at this restricted interface, which is advantageous in that no additional filter is required inside the capsule. This extraction geometry thus corresponds to the geometry that may be generally referred to in this application as an extraction plate with raised elements. The beverage flow is then collected in the channel and discharged through a small opening of well-defined size in the channel.

In the known systems of the prior art, the flow rate and pressure are determined by the inherent characteristics of the capsule and the performance of the pump.

The back pressure is highly dependent on the degree of compaction of the ground coffee in the capsule. The variability of pressure can be very high for the same brewed coffee. In particular, for certain coffee blends, particularly low particle size coffee, the pressure may vary from 5 bar to 15 bar.

Although the ingredient extraction space (e.g. with the capsule and/or the extraction chamber) is typically symmetrical along the general flow direction, such that the ingredient can be easily handled, it may be advantageous to obtain a directional flow path at the time of extraction, e.g. to obtain or increase or decrease certain extraction effects, such as crema formation or extraction intensity.

Disclosure of Invention

The present invention relates to a machine for preparing beverages. The beverage preparation machine may be a domestic or non-domestic machine. The machine can be used for preparing coffee, tea, chocolate, cocoa, milk, soup, baby food, etc.

Beverage preparation typically involves mixing a variety of beverage ingredients, such as water and powdered milk; and/or brewing beverage ingredients, such as brewing ground coffee or tea with water. One or more of such ingredients may be supplied in loose and/or agglomerated powder form and/or in liquid form, in particular in concentrate form. A carrier or diluent liquid (e.g., water) can be mixed with such ingredients to form a beverage.

Typically, a predetermined quantity of beverage corresponding to a portion (e.g., a serving) is formed and dispensed upon request by a user. The volume of this portion may be in the range of 25mL to 200mL, even up to 300mL or 400mL, for example the volume of a filled cup, depending on the type of beverage. The beverage formed and dispensed may be selected from the group consisting of pistachio (ristretto), espresso, extension coffee, cappuccino, latte macchiato, latte, american coffee, tea, and the like. In particular, the coffee machine may be configured to dispense espresso, e.g., with an adjustable volume of 20mL to 60mL per serving; and/or for dispensing extended length coffee, e.g. in a volume in the range of 70mL to 150mL per serving.

The present invention relates to a machine for preparing a beverage from ingredients. The machine comprises an extraction unit.

The extraction unit has an ingredient extraction seat, such as a seat delimiting an ingredient compartment and/or a seat for receiving an ingredient supplied within the capsule into the seat. A suitable capsule holder may be in the shape of a capsule chamber.

Thus, in one possible embodiment, the beverage may be prepared from a capsule containing beverage ingredients. The capsule may be of the type described above under the heading "technical field" and/or the capsule may comprise the ingredients described under the same heading.

The capsule may comprise a capsule body, for example a substantially straight or tapered body. The capsule may have a circular peripheral annular flange, e.g. a flexible or rigid flange, extending from a peripheral portion, e.g. an edge or surface of the capsule body. The capsule may be provided with an outlet membrane. The capsule may contain flavour ingredients for preparing tea, coffee, hot chocolate, cold chocolate, milk, soup or baby food.

Examples of ingredient extraction holders, such as extraction chambers, are disclosed in EP 1767129, WO 2012/025258, WO 2012/025259, WO 2013/127476, WO 2014/056641, WO 2014/096122, WO 2014/096123, WO 2015/155144 and WO 2015/155145.

The extraction unit (e.g. a holder) may be configured to extract ingredients not supplied within the capsule (e.g. loosely supplied ingredients or agglomerated or compacted ingredients without capsules) into the holder.

The extraction unit has an inlet arrangement for guiding water into the holder and a dispensing arrangement for guiding beverage out of the holder. The distribution arrangement has a face defining a downstream component of the seat.

The face is comprised of an upper portion and a lower portion, which portions are defined by a substantially horizontal physical or conceptual demarcation line located between the top and bottom ends of the face. Typically, these portions are substantially flush. For example, the portions extend in the same plane, or are substantially parallel and slightly offset, for example by a distance of no more than 2mm or 3mm or 4 mm.

This face may be realized in a dispensing arrangement, wherein the delimiting line is in its horizontal orientation or in a different orientation, i.e. at an angle to the horizontal with respect to the machine in its beverage dispensing orientation. Also, this face may be realized in a dispensing arrangement with its upper portion on top and its lower portion on bottom, either inverted or at an angle relative to the machine in its beverage dispensing orientation.

The upper portion is made up of an upper outflow channel and an upper impermeable member bounding the upper outflow channel. The upper portion has an upper surface area ratio transverse to the downstream flow direction in the seat as follows: the ratio of the surface area of the upper outflow channel to the surface area of the upper impermeable member. The upper surface area ratio defines an upper permeability value of the upper portion.

The lower portion is made up of a lower outflow channel and a lower impermeable member bounding the lower outflow channel. The lower portion has a lower surface area ratio transverse to the downstream flow direction as follows: the ratio of the surface area of the lower outflow channel to the surface area of the lower impermeable member. The lower surface area ratio defines a lower permeability value of the lower portion.

The upper permeability value and the lower permeability value may each range from about 0 to infinity.

The upper and lower outflow channels are generally configured to direct the beverage towards the beverage dispensing area.

The machine may have a droplet stop arrangement between the (upper and lower) outflow channel and the beverage dispensing area. Examples of droplet stoppers are disclosed in WO 2006/050769, WO 2012/072758, WO 2013/127907, WO 2016/050657, WO 2016/083488, WO 2018/069266 and EP 2017208722.3.

The dispensing region may be defined by a support for supporting a user-receptacle (e.g., a cup or mug). For example, the support is a support means connected to the external machine housing and/or machine frame, or the support means is external to such a machine, e.g. the machine itself is placed for dispensing a beverage. Typically, the external support means has a substantially horizontal surface for placing such machines, such as a table or a shelf.

The user-receptacle support may be associated with a drip tray, such as a drip tray supporting the support; and/or can move vertically relative to the housing below the outlet and/or away from the housing below the dispensing outlet, thereby enabling placement of user containers of different heights below the outlet.

Examples of suitable vessel supports are disclosed in EP 0549887, EP 1440639, EP 1731065, EP 1867260, US5,161,455, US5,353,692, WO 2009/074557, WO 2009/074559, WO 2009/135869, WO 2011/154492, WO2012/007313, WO 2013/186339, EP 2014198710, EP 2014198712 and EP 2014198715.

The total ratio of the upper surface area ratio (e.g., upper permeability value) to the lower surface area ratio (e.g., lower permeability value) of the face is greater than or less than 1, such as greater than 3 or less than 0.3, for example greater than 10 or less than 0.1, for example greater than 100 or less than 0.01.

The flow of water is facilitated on the upper part of the support when the permeability value on the top part of the face is greater than on the bottom part of the face. If the seat is only partially filled with the ingredient, for example when using a partially filled capsule, part of the water flowing through the seat is not or only rarely exposed to the ingredient contained in the seat. Therefore, the resulting beverage is less concentrated. Furthermore, when the extraction is an infusion process of, for example, tea or coffee, then the dilution of the beverage does not require the exhaustion of the ingredients (over-extraction) and possible dissolution of the undesired elements in the ingredients. The dilution may be obtained by mixing water containing an extract of the ingredient with water bypassing the ingredient.

When the permeability value on the top part of the face is smaller than on the bottom part of the face, all water is forced through the ingredient even when the seat is only partially filled with ingredient, for example when using a partially filled capsule. In this case, the concentration of the resulting beverage is higher. In order to avoid over-extraction when the extraction is an infusion process of, for example, tea or coffee, the volume of water passing through the ingredients should be limited in order to avoid or minimize undesired extraction elements in the resulting beverage.

Obviously, by varying the position and/or orientation of the face with respect to the extraction seat with respect to the machine in its beverage dispensing orientation, the same face can be used for concentrated or diluted extraction types, or possibly for intermediate extractions.

The position and/or orientation of the face with respect to the seat can be changed during the extraction of the ingredient in the seat and/or between two successive extractions.

The upper and lower portions of the face may constitute the overall height of the face of the downstream component defining the seat. The defining line may be located at a height of the face in the range of 15% to 85%, such as in the range of 30% to 70%, for example in the range of 40% to 60% of the total height.

The impermeable member of at least one of the upper portion and the lower portion may form a continuous flow-inhibiting portion. The flow-inhibiting portion can be configured such that beverage flowing out of the seat is inhibited (e.g., prevented) from flowing through the flow-inhibiting portion.

The flow-inhibiting portion may have a surface area transverse to the downstream flow direction in the range of 25% to 75%, such as in the range of 33% to 66%, for example in the range of 40% to 60% of the surface area transverse to the downstream flow direction of the face.

The flow-inhibiting portion may be an inherently closed member formed by the impermeable members of the faces.

Possible details of such a flow-inhibiting portion and its implementation in a machine are disclosed in co-pending patent application EP 18214475.8.

The flow-inhibiting portion may be an inherently open part of the face, for example provided with at least one through-hole closed by a sealing arrangement (e.g. a movable temporary sealing arrangement) closing the open part. The sealing arrangement may be located: upstream of the intrinsic opening means, for example in the seat, and/or downstream of the closed intrinsic opening means, generally as upstream or downstream jacket or plate members; and/or in the opening of the inherent opening feature, for example as a filler.

The distribution arrangement may comprise a flow-restricting member movably arranged relative to the face between a normal outflow position and a reduced outflow position in which a surface area transverse to a downstream flow direction of the upper and/or lower outflow channel is reduced compared to the normal outflow position by blocking a portion of the upper and/or lower outflow channel. The blocked upper and/or lower outflow channel can be partially or completely closed in the reduced position.

The flow restriction member may have an elastically deformable face configured to control the level of reduction by pressure applied by the flow restriction member towards the face.

The flow-restricting member may have one or more protruding members configured to be inserted into the upper outflow channel and/or the lower outflow channel.

The flow restriction member may have one or more of the above-mentioned faces: is delimited by a delimiting part such that a part of the upper outflow channel and/or the lower outflow channel remains free of obstructions in the reduced outflow position or extends over the entire upper outflow channel and/or the lower outflow channel.

The flow-restricting member may have a plurality of different components that are individually positionable, each component being configured to block only a portion of the upper and/or lower outflow passages in its reduced outflow position.

The flow-restricting member may have an actuating member that is automatically actuated, for example by a manual or motorized actuator.

Possible details of such flow-limiting means and their implementation in a machine can be found in co-pending patent application EP 18214451.9.

The upper and lower portions can be in different positions relative to the seat, for example pivotable about a downstream flow direction, so as to control the flow path of water through the ingredient when in the seat depending on the position of the flow-through portion.

When the upper and lower portions are in different positions, the defined line generally follows such positions.

The face may be made of a wall (e.g. a plate-like or sheet-like member) forming the beverage guiding structure, through which wall the outflow channel extends. At least one of the outflow channels may be formed by at least one of: one or more through holes; a network structure; a porous structure; and a porous structure extending through the wall.

The outflow channel may be configured to guide the total beverage flow from the seat through the wall via a total guide inlet at the seat side of the wall and out from a total guide outlet of the wall via a beverage outlet towards a dispensing area (such as a dispensing area defined by a support for supporting a user container). The wall may be associated with a flow control device configured to control the flow of beverage directed along the outflow channel.

The flow control device may have a blocking portion, such as an at least substantially beverage impermeable portion, extending adjacent the wall so as to block at least a portion of the general guide inlet and/or outlet to prevent or inhibit beverage from passing through such a blocked guide portion.

The flow control device may have one or more control sides adapted to define a controlled passage from the blocked portion through which the total beverage flow passes through a non-blocked portion of the total guide inlet and/or outlet, which may be adjacent to the blocked portion.

The blocking portion and the control side may be manually and/or automatically operable, e.g. relatively translatable and/or rotatable, on the wall in order to change the relative position and/or relative size and/or shape of the blocking portion and the non-blocking portion of the total guide inlet and/or outlet. The blocking portion and the control side are operable on the wall to selectively enter a plurality of different configurations, for example at least two configurations, such as in the range of 3 to 30, for example 4 to 20 or 5 to 10 configurations, in terms of relative size and/or relative position and/or shape.

The control side may comprise at least one of a circular side, a radial or diametric side, and a polygonal side.

The control side may define the controlled passage with a cross-section having a shape that is at least one of polygonal, curvilinear, such as circular, convex, and concave, for example, the shape is a curved sector or a circular sector.

Further possible details of such a flow control device and its implementation in a machine are described in co-pending patent application EP 18214459.2.

The extraction support may be configured for receiving an ingredient capsule provided with an outlet membrane. The inlet arrangement may be associated with a piercing and/or cutting arrangement configured to pierce and/or cut the water inlet into the ingredient capsule in the ingredient extraction seat such that water circulating along the inlet arrangement enters the capsule via the water inlet. The dispensing arrangement may comprise one or more piercing and/or cutting elements projecting upstream and configured for forming a beverage outlet aperture in the outlet membrane.

The holes may be provided in the outlet membrane by piercing and/or cutting elements as follows: providing an aperture in the membrane prior to supplying water into the seat via the inlet arrangement, e.g. at or after inserting the capsule into the seat; and/or by supplying water at a pressure in the range of 5 to 20 bar, such as 8 to 15 bar, for example, to cause a pressure increase in the capsule to push the outlet membrane against the piercing and/or cutting element.

At least one such piercing and/or cutting element may comprise a piercing and/or cutting element formed from or secured to a face, such as a piercing and/or cutting element extending from adjacent an upper or lower outflow channel or a portion of such a channel. For example, a plurality of such piercing and/or cutting elements are formed by or secured to a face.

At least one such piercing and/or cutting element may comprise a piercing and/or cutting element that is movable through the face, for example via corresponding channels, between: a deployed position in which the movable piercing and/or cutting element extends beyond the face into the holder for providing a hole in the exit membrane in the holder by such a movable piercing and/or cutting element; and a retracted position in which the piercing and/or cutting element is so retracted relative to its deployed position, e.g., away from the holder, to prevent formation of a hole in the exit membrane in the holder by such a movable piercing and/or cutting element. Typically, the movable piercing and/or cutting element is fixed to or integral with a support (e.g. a support supporting a plurality of such piercing and/or cutting elements) driven by a drive member, for example actuated by a manual or automatic, e.g. motorized, actuator. The machine may comprise more than one support supporting one or more piercing and/or cutting elements, which can in particular be actuated independently to be able to pierce and/or cut different areas of the orofilm as required to obtain different extractions. The machine may include an upper support, for example associated with the upper portion, supporting piercing and/or cutting elements, and a lower support, for example associated with the lower portion, supporting piercing and/or cutting elements.

Possible implementation details of such an arrangement can be found in co-pending patent application EP 18214480.8.

At least one such piercing and/or cutting element may comprise a piercing and/or cutting element associated with an opening control arrangement configured to control the formation of a hole in the exit membrane by the at least one piercing and/or cutting element. The opening control arrangement may comprise at least one neutralizing member movable adjacent the piercing and/or cutting element between an operative position in which the piercing and/or cutting element is prevented from forming a hole in the exit membrane, and a rest position in which the piercing and/or cutting element is capable of forming a hole in the exit membrane. The piercing and/or cutting element may project upstream from the upstream along an opening direction, for example an opening direction substantially parallel to the downstream flow direction, the neutralizing member being movable between its operating position and rest position as follows: at least substantially parallel to the opening direction; and/or transverse to the opening direction.

Further possible details of the opening control arrangement and its specific implementation in the machine are disclosed in co-pending patent application EP 18214470.9.

The extraction support may be configured for receiving an ingredient capsule provided with an outlet membrane. The inlet arrangement may be associated with a piercing and/or cutting arrangement configured to pierce and/or cut the water inlet into the ingredient capsule in the ingredient extraction seat such that water circulating along the inlet arrangement enters the capsule via the water inlet. The face may lack any piercing and/or cutting elements for piercing and/or cutting the oral film. For example, the beverage outlet opening is provided in the outlet membrane as follows: prior to receiving the capsule in the extraction seat, for example when the capsule is manufactured or subsequently conditioned before reaching the seat, for example in a machine of this type; and/or by supplying water into the capsule causing a pressure rise in the capsule to tear and/or break the membrane, for example in order to open a pre-weakened part of the membrane and/or to actuate a membrane opening element comprised within the capsule.

Self-opening capsules are disclosed, for example, in CH 605293 and WO 03/059778.

For example, EP 512470 and EP 2068684 disclose opening a capsule by means of piercing elements in a machine plate.

Examples of suitable mixing units with mixing chambers are disclosed in WO 2008/037642 and WO 2013/026843.

The face may have an at least substantially disc shape.

At least one of the lower and upper impermeable members may form a circular sector or ring sector, for example a generally semicircular disk, such as a circular sector or ring sector having a center at least generally concentric with the circle of the face. The circular sector or ring sector may extend to the circular edge of the circular shape of the face. The central angle of the circular or ring sector may be in the range of 60 ° to 300 °, such as in the range of 90 ° to 270 °, for example in the range of 120 ° to 240 °, for example in the range of 150 ° to 210 °.

At least one of the lower impermeable member and the upper impermeable member may form a disc segment. The disk segments may have a disk center at least approximately concentric with the shape of the face. The surface area ratio of the disc segments and the flow-through portion may be in the range of 0.2 to 5, such as 0.5 to 2, for example 0.66 to 1.5, for example 0.75 to 1.33.

The upper outflow channel and the lower outflow channel together have a total number of flow openings of: in the range of 3 to 35, such as in the range of 5 to 30, for example in the range of 10 to 25; and/or each flow opening has a minimum diameter transverse to the beverage outflow direction along the opening in the range of about 0.1mm to 1mm, such as 0.3mm to 0.8mm, for example 0.4mm to 0.6 mm.

The flow holes may be of the same size or of different sizes.

The extraction support may be defined by a first part and a second part, which are relatively movable between: an open position for inserting ingredients (e.g. ingredients within the aforementioned capsule) into the extraction seat and/or for removing such ingredients from the seat; and a closed position for extracting the ingredient in the seat.

The first and second components may be configured such that the first component supports the face and the second component supports the inlet arrangement.

When using a closed capsule, the first and second parts may comprise a capsule opener, such as a blade and/or a tearing tool, e.g. a plate with a tearing profile, e.g. from NespressoTMPanels with tear profiles known to the machines or disclosed in EP0512470, EP 2068684 and WO 2014/076041 and the references cited therein.

The first and second members may be configured such that the first and second members are relatively movable by an actuator, such as by a user handle, or by an electric motor (e.g., an actuator connected to at least one of the first and second members by a transmission, such as one or more of a gear, belt, cam and cam follower, lever, and/or hydraulic transmission). Such electric motors may be controlled by a control unit for controlling the water supply arrangement, such as a unit comprising processing means (e.g. a controller and/or a user interface).

Examples of motors implemented to actuate such first and second components are disclosed in EP 1767129, WO 2012/025258, WO 2012/025259, WO 2013/127476, WO 2014/056641, WO 2014/096122, WO 2014/096123, WO 2015/155144 and WO 2015/155145.

One of the first and second components may be stationary relative to the external machine housing and the other of the first and second components may be movable relative to the external machine housing.

Examples of suitable first and second component arrangements are disclosed in WO 2005/004683, WO2007/135136, WO 2009/043630, WO 2017/037212, WO2017/037215, PCT/EP18/064138 and PCT/EP 18/064141.

The inlet arrangement may be fluidly connected to the water supply arrangement via a water guide.

Examples of suitable first and second component arrangements are disclosed in WO 2005/004683, WO2007/135136, WO 2009/043630, WO 2017/037212, WO2017/037215, PCT/EP18/064138 and PCT/EP 18/064141.

The water supply arrangement may comprise at least one of: a water source for supplying water to the inlet arrangement, such as a water tank and/or a connector to an external water supply line; a water drive, such as a pump, for driving water to the inlet arrangement; and a thermal regulator, such as a heater and/or cooler, for thermally regulating the water supplied or to be supplied to the inlet arrangement, such as a water flow thermal regulator or a water reservoir thermal regulator.

The thermal regulator may be a water heater, a heating block or an On Demand Heater (ODH), for example of the ODH type disclosed in EP 1253844, EP 1380243 and EP 1809151.

Examples of pumps and their incorporation in beverage machines are disclosed in WO 2009/150030, WO 2010/108700, WO2011/107574 and WO 2013/098173.

The water supply arrangement may be associated with a control unit or the aforementioned control units for controlling the water supply arrangement, such as units comprising processing means (e.g. a controller and/or a user interface).

The seat may be associated with an unextracted ingredient insertion channel (e.g., extending from the exterior of such machines) and/or an extracted ingredient evacuation channel (e.g., toward a waste ingredient collector). At least one of the channels may be associated with a guide (such as a rail or a groove) for cooperating with and guiding the capsule along the channel to and/or from the seat, and/or with a stop for fixing the capsule at about the level of the seat.

Examples of waste ingredient collectors are disclosed in EP 1867260, WO 2009/074559, WO 2009/135869, WO2010/128109, WO 2011/086087, WO 2011/086088, WO 2017/118713, WO 2017/148965 and EP 2018156589.

The insertion channel (when present) may be associated with an ingredient barrier, such as a gate or door or hatch, for selectively allowing and preventing passage of ingredients along the channel. Details of suitable barriers for ingredients, such as ingredients supplied within capsules, are disclosed in WO 2012/126971, WO 2014/056641, WO 2014/056642 and WO 2015/086371.

The interaction between the first and second parts (and optionally the transfer channel) and the ingredient capsule may be of the type disclosed in WO 2005/004683, WO 2007/135135, WO2007/135136, WO 2008/037642 and WO 2013/026856.

When present, the control unit may have a control circuit, for example for controlling the liquid driver or the above-mentioned liquid driver and/or the thermal regulator or the above-mentioned thermal regulator. The control circuit may comprise a microcontroller and/or a microprocessor.

The control unit may comprise an ingredient sensor, such as an ingredient capsule sensor.

Details of suitable capsule sensors are disclosed in WO 2012/123440, WO 2014/147128, WO 2015/173285, WO 2015/173289, WO 2015/173292, WO 2016/005352, WO 2016/005417, PCT/EP18/065613, EP3275345 and EP 3275346.

The control unit may incorporate a user interface, such as a user interface connected to the control circuit or control circuits described above. The user interface may be of a known type, for example as disclosed in WO 2010/037806, WO 2011/020779, WO 2016/083485, WO2017/037215 and PCT/EP 18/064138.

The control unit may have a sensor for sensing the presence of a user-receptacle (e.g. a cup or mug) in or in the area to which beverage is dispensed from the beverage processing line. Such an arrangement is disclosed for example in WO 2018/046400.

The invention also relates to the use of an ingredient, such as an ingredient contained in a capsule as described above, for extraction in a machine as described above. The ingredient may be selected from at least one of tea, coffee and cocoa.

The pressure is typically measured downstream of the pump and upstream of the water inlet, for example in the fluid line between the water inlet and the pump. By the presence of a check valve, for example at the water inlet of the injection member, and/or a restriction provided in the water inlet of the injection member, or by a piercing member engaged in the entry wall of the capsule, and/or by ingredients and/or other obstacles in the capsule, it is possible to reduce the pressure in the extraction chamber or the capsule compared to such measured pressure.

Detailed Description

Fig. 1 to 3 show an exemplary embodiment of a beverage machine 1 for preparing a beverage 110 comprising an extraction unit 2 according to the invention, wherein the variants according to the invention shown in fig. 4 to 22 can be implemented, wherein the same reference numerals generally denote the same or similar elements and/or the same or similar functions.

The extraction unit 2 has an ingredient extraction seat 20, such as a seat delimiting an ingredient compartment and/or a seat 20 for receiving an ingredient 102 supplied within the capsule 100 into the seat 20. The extraction unit 2 has an inlet arrangement 21 for guiding water into the support 20. The extraction unit 2 comprises a dispensing arrangement 22 for guiding the beverage 110 out of the seat 20, the dispensing arrangement 22 having a face 220 delimiting a downstream part of the seat 20.

The face 220 is made of an upper portion 220a and a lower portion 220 b. Such portions 220a,220b are bounded by a substantially horizontal physical or conceptual bounding line 220c located between the top and bottom ends of face 220. The upper portion 220a and the lower portion 220b are typically at least substantially flush. For example, the portions 220a,220b extend in the same plane, or are substantially parallel and slightly offset, for example by a distance of no more than 2mm or 3mm or 4 mm.

The upper portion 220a is made of an upper outflow channel 222a and an upper impermeable member that defines the upper outflow channel 222 a. The upper portion 220a has an upper surface area ratio transverse to the downstream flow direction 200 in the support 20 as follows: the ratio of the surface area of the upper outflow channel 222a to the surface area of the upper impermeable member.

The lower portion 220b is made up of a lower outflow channel 222b and a lower impermeable member that defines the lower outflow channel. The lower portion 220b has a lower surface area ratio transverse to the downstream flow direction 200 as follows: the ratio of the surface area of the lower outflow channel 222b to the surface area of the lower impermeable member.

The total ratio of the upper surface area ratio (e.g., upper permeability value) to the lower surface area ratio (e.g., lower permeability value) of the face 220 is greater than or less than 1, such as greater than 3 or less than 0.3, for example greater than 10 or less than 0.1, for example greater than 100 or less than 0.01.

In fig. 20, the flow 105, 106, 107 of water is shown through the seat 20, for example through the capsule 100 partially filled with ingredient 102 (up to the dotted level in the figure), wherein the total ratio of the upper surface area ratio to the lower surface area ratio of the face 220 is 1. Such a flow is known from prior art machines or from machines operating in extraction mode according to the invention, as shown for example in fig. 11 (the flow restriction member 35 in the normal outflow position). Since the upper and lower permeability values are the same, no preferential flow is created, which results in an average extraction and an average of the resulting beverage 110.

The upper flow 107 of water is facilitated on the upper part of the support 200 when the upper surface area ratio of the upper part 220a of the face 220 is greater than the lower surface area ratio of the face 200, the flows 105, 106 of water also being present in the lower part of the support 200 (although at a reduced rate) due to the pressure of the water injected into the support 20, as shown in figure 21. If the support 20 is only partially filled with the ingredient 102, for example when using a partially filled capsule 100, the upper portion 107 of the water flowing through the support 20 is not or only rarely exposed to the ingredient 102 contained in the support 20. Thus, the resulting beverage 110 is less concentrated. Furthermore, when the extraction is an infusion process of, for example, tea or coffee 102, then the dilution of the beverage 110 does not require the exhaustion (over-extraction) of the ingredients 102 and possible dissolution of the unwanted elements in the ingredients. The dilution may be obtained by mixing the water 105, 106 containing the extract of the ingredient and the water 107 that (at least substantially) bypasses the ingredient 102. With this arrangement, a high quality long coffee or american coffee can be obtained.

When the upper surface area ratio of the upper portion 220a of the face 220 is lower than the lower surface area ratio of the lower portion 220b of the face 220, substantially all of the water 105, 106, 107 is forced through the ingredient 102 even when the support 20 is only partially filled with the ingredient 102, for example when using a partially filled capsule 100. See fig. 22. In this case, the resulting beverage 110 is more concentrated. In order to avoid over-extraction when the extraction is an infusion process of, for example, tea or coffee 105, the volume of water 105, 106, 107 passing through the ingredient 102 should be limited in order to avoid or minimize undesired extraction elements in the resulting beverage 110. With this arrangement, high quality espresso coffee or jatropha is obtained.

Obviously, by varying the position and/or orientation of the face 220 with respect to the extraction seat 20 with respect to the machine 1 in its beverage dispensing orientation, the same face 220 can be used for either concentrated or diluted extraction types, or possibly for intermediate extractions.

The position and/or orientation of the face 220 relative to the support 20 may be changed during extraction of the ingredient 102 in the support 20 and/or between two successive extractions.

The upper portion 220a and the lower portion 220b of the face 220 may constitute the overall height of the face 220 defining the downstream component of the seat. The defining line 220c may be located at a height of the face 220 in the range of 15% to 85%, such as in the range of 30% to 70%, for example in the range of 40% to 60% of the total height.

The impermeable member of at least one of the upper portion 220a and the lower portion 220b may form a continuous flow-inhibiting portion. Such a flow-inhibiting portion can be configured such that beverage 110 flowing out of the holder 20 is inhibited (e.g., prevented) from flowing through the flow-inhibiting portion. See fig. 4.

The flow-inhibiting portion may have a surface area transverse to the downstream flow direction 200 in a range of 25% to 75%, such as in a range of 33% to 66%, for example in a range of 40% to 60%, of the surface area of the downstream flow direction 200 transverse to the face 220.

The flow-inhibiting portion may be an inherently closed member formed by the impermeable member of face 220.

The flow inhibiting portion may be an inherently open part of the face 220, e.g. provided with at least one through hole 222a,222b closed by a sealing arrangement 35 (e.g. a movable temporary sealing arrangement 35) closing the open part. For example, the sealing arrangement 35 is located: upstream of the inherent opening feature, for example in the seat 20, and/or downstream of the closed inherent opening feature, typically as an upstream or downstream jacket or plate member; and/or in the opening of the inherent opening feature, for example as a filler.

The distribution arrangement 22 may comprise a flow-restricting member 35, schematically shown in fig. 2 and 3 and in fig. 9 to 12, which is movably arranged relative to the face 220 between a normal outflow position and a reduced outflow position in which the surface area transverse to the downstream flow direction 200 of the upper outflow channel 222a and/or the lower outflow channel 222b is reduced compared to the normal outflow position. This reduction is obtained by blocking a portion of the upper outflow channel 222a and/or the lower outflow channel 222 b. The blocked upper outflow channel 222a and/or lower outflow channel 222b may be partially or completely closed in the reduced position.

The flow restriction member 35 may have an elastically deformable face 36 configured to control the level of reduction by pressure applied by the flow restriction member 35 towards the face 220. See fig. 9.

The flow restriction member 35 may have one or more protruding members 37 configured to be inserted into the upper outflow channel 222a and/or the lower outflow channel 222 b. See fig. 10.

The flow restriction member 35 may have one or more of the faces 36 described above which: is delimited by a delimiting part 37, for example a cut, so that parts of the upper outflow channel 222a and/or the lower outflow channel 222b remain free of obstruction in the reduced outflow position (fig. 9), or extend over the entire upper outflow channel 222a and/or the lower outflow channel 222b (fig. 10 to 12).

The flow restriction member 35 may have a plurality of different components that can be individually positioned, each component configured to block only a portion of the upper and/or lower outflow passages 222a,222b in its reduced outflow position.

The flow-restricting member 35 may have an actuating member 38 that is actuated, for example, manually or automatically by a motorized actuator.

The upper portion 220a and the lower portion 220b can be in different positions relative to the support 20, for example pivotable about the downstream flow direction 200, in order to control the flow path of water through the ingredient 102 when in the support 20 depending on the position of the flow-through portion 221. See fig. 4-6.

The face 220 may be made of a wall 223 (e.g. a plate-like or sheet-like member 223) forming a beverage guiding structure, through which the outflow channels 222a,222b extend. At least one of the outflow channels 222a,222b may be formed by at least one of: one or more through holes; a network structure; a porous structure; and a porous structure extending through the wall 223.

The outflow channels 222a,222b may be configured to guide the total flow of beverage 110 from the seat 20 through the wall 223 via a total guiding inlet at the seat side of the wall 223 and out from a total guiding outlet of the wall 223 towards the dispensing area 1 'via the beverage outlet 220'. The dispensing area 1' may be defined by a support for supporting a user container.

The wall 223 may be associated with a flow control device 23a,23b configured to control the flow of beverage 110 directed along the outflow channel 222a,222 b. See fig. 13 and 14.

The flow control devices 23a,23b may have blocking portions 230a,230b, such as at least substantially beverage impermeable portions, extending adjacent the wall 223 so as to block at least a portion of the general leading inlet and/or outlet to prevent or inhibit passage of the beverage 110 through such blocked leading portions. The flow control means 23a,23b may have one or more control sides 231a,231b adapted to delimit from the blocking portions 230a,230b a controlled channel 233 through which the total beverage 110 flows through non-blocking portions of the total guide inlet and/or outlet, which non-blocking portions are adjacent to the blocking portions 230a,230 b.

The blocking portions 230a,230b and the control sides 231a,231b may be manually and/or automatically operable on the wall 223, e.g. relatively translatably and/or rotatably, in order to change the relative position and/or relative size and/or shape of the blocking and non-blocking portions of the total lead-in and/or outlet, such as being operable on the wall 223 to selectively enter a plurality of different configurations in terms of relative size and/or relative position and/or shape, such as at least two configurations, such as in the range of 3 to 30, e.g. 4 to 20 or 5 to 10 configurations.

The control sides 231a,231b may include at least one of a circular side, a radial or diametric side, and a polygonal side.

The control sides 231a,231b may define the controlled passage 233 with a cross-section having a shape that is at least one of polygonal, curvilinear, such as circular, convex, and concave, for example, the shape is a curved sector or a circular sector.

The extraction support 20 may be configured for receiving an ingredient capsule 100 provided with an outlet membrane 101. For example, the inlet arrangement 21 is associated with a piercing and/or cutting arrangement 21a configured to pierce and/or cut a water inlet into an ingredient capsule 100 in the ingredient extraction support 20 such that water circulating along the inlet arrangement 21 enters the capsule 100 via the water inlet.

The dispensing arrangement 22 may comprise one or more piercing and/or cutting elements 225,33 protruding upstream and configured for forming a beverage outlet aperture in the outlet membrane 101.

Such holes may be provided in the outlet film 101 by the piercing and/or cutting elements 225,33 as follows: before supplying water into the support 20 via the inlet arrangement 21, e.g. at or after inserting the capsule into the support 20, an aperture is provided in the outlet membrane 101; and/or by causing a pressure increase in the capsule 100 by supplying water, for example, at a pressure in the range of 5 to 20 bar, such as in the range of 8 to 15 bar, thereby pushing the outlet membrane 101 against the elements 225, 33.

At least one such piercing and/or cutting element 225,33 can include a piercing and/or cutting element 225 formed by or secured to the face 220, such as an element 225 extending from adjacent the upper outflow channel 222a, or the lower outflow channel 222b, or a portion of such a channel.

For example, a plurality of such piercing and/or cutting elements 225 are formed by or secured to face 220. See fig. 2-8 and 17-19.

At least one such piercing and/or cutting element 225,33 may comprise a piercing and/or cutting element 33 capable of moving through face 220, for example via a corresponding channel 32, between: a deployed position in which the movable piercing and/or cutting element 33 extends beyond the face 220 into the support 20 for providing a hole in the exit membrane 101 in the support 20 by such a movable piercing and/or cutting element 33 (fig. 8); and a retracted position in which the element 33 is so retracted with respect to its deployed position, for example, away from the support 20, as to prevent the formation of a hole in the exit membrane 101 in the support 20 by such a movable piercing and/or cutting element 33 (fig. 7).

Typically, a movable piercing and/or cutting element 33 is fixed to or integral with a support 31 (e.g. a support supporting a plurality of such piercing and/or cutting elements 33) driven by a drive member 30, for example actuated by a manual or automatic, e.g. motorized, actuator. The machine 1 may comprise more than one support 31 supporting one or more piercing and/or cutting elements 33, which can in particular be actuated independently to be able to pierce and/or cut different areas of the orofilm as required to obtain different extractions. The machine 1 may comprise an upper support 31, for example associated with the upper portion 220a, supporting the piercing and/or cutting elements 33, and a lower support 31, for example associated with the lower portion 220b, supporting the piercing and/or cutting elements 33.

At least one such piercing and/or cutting element 225,33 may comprise a piercing and/or cutting element 225 associated with an opening control arrangement 240 configured to control the formation of a hole in the exit membrane 101 by the at least one piercing and/or cutting element 225. The opening control arrangement 240 may comprise at least one neutralizing member 240a movable adjacent to the piercing and/or cutting element 225 between an operative position in which the piercing and/or cutting element 225 is prevented from forming a hole in the exit membrane 101, and a rest position in which the piercing and/or cutting element 225 is capable of forming a hole in the exit membrane 101. For example, the piercing and/or cutting elements 225 project upstream from the face 220 along an opening direction 225', for example an opening direction substantially parallel to the downstream flow direction 200, the neutralizing member 240 being movable between its operating position and rest position as follows: at least substantially parallel to the opening direction 225'; and/or transverse to the opening direction 225'. See fig. 15-17.

The extraction support may be configured for receiving an ingredient capsule provided with an outlet membrane, optionally the inlet arrangement being associated with a piercing and/or cutting arrangement configured to pierce and/or cut the water inlet into the ingredient capsule in the ingredient extraction support such that water circulating along the inlet arrangement enters the capsule via the water inlet. The face defining the abutment may lack any piercing and/or cutting elements for piercing and/or cutting the aperture membrane. The beverage outlet opening may be provided in the outlet membrane as follows: prior to receiving the capsule in the extraction seat, for example when the capsule is manufactured or subsequently conditioned before reaching the seat, for example in a machine of this type; and/or by supplying water into the capsule causing a pressure rise in the capsule to tear and/or break the membrane, for example in order to open a pre-weakened part of the membrane and/or to actuate a membrane opening element comprised within the capsule.

The face 220 may have an at least substantially disc shape. See fig. 4-6 and 11-19. At least one of the lower impermeable member and the upper impermeable member may form:

-a circular sector or ring sector, for example a generally semicircular disc, such as a circular sector or ring sector having a centre at least substantially concentric with the circle of the face, optionally extending to the circular edge of the circular shape of the face, for example the central angle of the circular sector or ring sector is in the range of 60 ° to 300 °, such as in the range of 90 ° to 270 °, for example in the range of 120 ° to 240 °, for example in the range of 150 ° to 210 °; or

-a disc segment, optionally: the disk segment has a disk center at least approximately concentric with the shape of the face; and/or the surface area ratio of the disc segments and the flow-through portion is in the range of 0.2 to 5, such as 0.5 to 2, for example 0.66 to 1.5, for example 0.75 to 1.33.

The total number of flow holes 222a,222b that the upper outflow passage 222a and the lower outflow passage 222b together have may be: in the range of 3 to 35, such as in the range of 5 to 30, for example in the range of 10 to 25; and/or each flow opening 222a,222b has a minimum diameter transverse to the beverage outflow direction along the opening in the range of about 0.1mm to 1mm, such as 0.3mm to 0.8mm, for example 0.4mm to 0.6 mm. See fig. 2, 3, 11, 19.

The flow holes 222a,222b may all be the same size (fig. 19) or may be different sizes (fig. 18).

The extraction support 20 can be delimited by a first part 24 and a second part 25, which can be relatively moved between: an open position for inserting ingredients 102 (e.g. ingredients within the capsule 100 described above) into the extraction seat 20 and/or for removing such ingredients 102 from the seat 20; and a closed position for extracting the ingredient 102 in the seat 20. See fig. 2 and 3.

The first and second members 24, 25 may be configured such that the first member 24 supports the face 220 and the second member 25 supports the inlet arrangement 21.

The first and second members 24, 25 can be configured such that the first and second members 24, 25 can be moved relative to each other by an actuator, such as by a user handle, or by an electric motor 3 (e.g., an actuator connected to at least one of the first and second members 24, 25 by a transmission 4, such as one or more of a gear 41, a belt, a cam 42, and a cam follower, a lever, and/or a hydraulic transmission). For example, the electric motor 3 is controlled by a control unit 10 for controlling the water supply arrangement 5, such as the unit 10 with processing means (e.g. a controller 11 and/or a user interface 12).

The first and second parts 24, 25 may be configured such that one of the first and second parts 24, 25 is stationary relative to the external machine housing 1 "while the other of the first and second parts 24, 25 is movable relative to the external machine housing 1".

The inlet arrangement 21 may be fluidly connected to the water supply arrangement 5 via a water guide 9.

The water supply arrangement 5 may comprise at least one of: a water source 6 for supplying water to the inlet arrangement 21, such as a water tank and/or a connector to an external water supply line; a water drive 7, such as a pump, for driving water to the inlet arrangement 21; and a thermal regulator 8, e.g. a heater and/or a cooler, for thermally regulating the water supplied or to be supplied to the inlet arrangement 21, such as a water flow thermal regulator or a water reservoir thermal regulator.

The water supply arrangement 5 may be associated with a control unit for controlling the water supply arrangement 5 or the control unit 10 described above, such as the unit 10 comprising processing means (e.g. the controller 11 and/or the user interface 12).

The seat 20 may be associated with an unextracted ingredient insertion channel 20a (e.g. extending from the exterior of such a machine 1) and/or an extracted ingredient evacuation channel 20b (e.g. towards a waste ingredient collector). The channels 20a,20b may be associated with a guide 20c (such as a rail or groove) for cooperating with and guiding the capsule 100 along the channel to and/or from the seat 20, and/or with a stop 20d for fixing such capsule 100 at about the level of the seat 20.
