The present invention relates to be used to prepare the system of the predetermined amount of beverage that is suitable for consuming, system is provided with exchangeable reservoir and equipment, equipment is equiped with the fluid allocation device that removably is connected in container, the fluid allocation device is used for allotting the first fluid at least of at least one amount to removable container, all liquid in this way of first fluid and/or gas, especially all water in this way and/or steam under pressure; And exchangeable reservoir is provided with at least one storage space of having filled second fluid, all enrichedmaterials in this way of second fluid.

The invention still further relates to the exchangeable reservoir that is configured to the equipment of being connected in, equipment is provided with the fluid allocation device, the fluid allocation device is used for allotting the beverage that first fluid at least is suitable for consuming with preparation to exchangeable reservoir, all gas in this way of first fluid and/or liquid under pressure; And removable container has been provided with filling at least one storage space of second fluid, all enrichedmaterials in this way of second fluid.

A kind of like this system and a kind of like this exchangeable reservoir itself are known.

According to known system, equipment for example is provided with pin, the wall of needle-penetration storage space in use, with first fluid for transporting to storage space.In storage space, the first fluid and second fluid mix, so that the beverage that acquisition is suitable for consuming, then the beverage slave unit flows out to be consumed.

The shortcoming of known system is: the concentration of the amount of beverage that it is allotted may be with not controlled way change.The fact is: if when beginning to prepare beverage, storage space still contains the second many relatively fluids, and the beverage that leaves exchangeable reservoir will comprise second fluid and the first fluid that contains relative low concentration of relative high concentration.On the contrary, at preparation on-cycle end, the beverage that flows out from container will contain second fluid of relative low concentration and the first fluid of relative high concentration.In addition, for known system, unless pass through to change form, the form of second fluid and/or the amount of the first fluid or second fluid of first fluid, otherwise just can not be user's suitable manner is changed the character of beverage.The purpose of this invention is to provide a kind of system, if desired, use described system and can prevent above-mentioned shortcoming, and further can realize other advantage.

Therefore, system according to the present invention is characterised in that container also is provided with: at least the first blending box; At least one flows out opening, and it is communicated with first blending box on fluid, to allot beverage from first blending box; At least one fluid communication between the storage space and first blending box is to be allotted to first blending box to second fluid; Enter opening with at least one, it removably is connected in the outlet opening of fluid allocation device, first fluid is allotted to first blending box; Native system also is provided with proportioner, it is configured to batching mode second fluid be supplied to transport to first blending box from storage space, and the fluid allocation device is configured under pressure first fluid be supplied to transport to first blending box, make that first fluid and second fluid mix in first blending box, to obtain beverage, beverage leaves exchangeable reservoir through flowing out opening then.

At present, second fluid is allotted to first blending box from storage space with batching mode, and second concentration of fluid of leaving in the beverage of first blending box can be accurately controlled.The fact is: second fluid is allotted to first blending box with batching mode.Therefore first fluid also can be allotted to first blending box with batching mode by the fluid allocation device, makes that the character of the beverage that is mixed and made in first blending box by the first fluid and second fluid can be limited well.

Especially, proportioner relates to controlled active proportioner, and controlled active proportioner comes second fluid for transporting to fixedly blending box by second fluid being applied increased pressure or power.Then second fluid is failed and can be controlled as desired to the confession of first blending box.Particularly, keep: described system also is provided with the control setup that is used to control proportioner and fluid allocation device herein.Proportioner and fluid allocation device for example can be controlled by control setup independently of one another.

More at large, described system is configured to like this: fluid allocation device and proportioner can supply the defeated first fluid and second fluid respectively to first blending box independently of one another.By this way, confession throughput rate that the preparation of beverage can be by controlling first and second fluid independently of one another and cycle and at random change.

Preferably also further be: described system also is provided with the constriction that is included in the fluid flow passages, and fluid flow passages arrives from the fluid allocation device and flows out opening through enter opening and first blending box of the outlet opening of fluid allocation device, container.Jet and/or mist vapour have for example been produced with constriction.

Be preferably, described system also is provided with the constriction that is included in the fluid flow passages, and fluid flow passages is through outlet opening and enter opening and arrive first blending box from the fluid allocation device.Herein, for example constriction is configured to like this: in use, produced the jet of the first fluid that sprays into first blending box with constriction.The result is that first and second fluid can mix in first Room well.

Particularly, described system also is provided with to the air admission opening of first blending box for defeated air, makes that in use air is whipped in the beverage, to obtain beverage with fine-bubble froth layer.According to preferential embodiment, the air admission opening constitutes the part of container.Because the air admission opening constitutes the part of exchangeable reservoir, for example for each exchangeable reservoir, the size of air admission opening can pre-determine, so that determine how many air each exchangeable reservoir has be whipped in the beverage.According to the type of the beverage that will prepare, can determine the size of air admission opening.Coffee concentrate and first fluid relate to for example water if second fluid for example relates to, and tend to prepare the coffee with fine-bubble froth layer simultaneously, the size of air admission opening can be selected relatively little.If opposite, exchangeable reservoir has been filled for example second fluid of milk concentrates form, and what again first fluid related to simultaneously is water, tends to beverage simultaneously and contains the milk of being with foam, and the air admission opening can be relatively large.Because in this example, the air admission opening constitutes the part of exchangeable reservoir, and the customer need not be provided with anything.All these can be optimized in advance by maker.

Particularly, constriction constitutes the part of container.If desired, also by this way, the size of constriction can be according to the form of the beverage that will prepare and for example pre-determine according to the form that is present in second fluid of storage space in the present example.If constriction is for example less relatively, can produce for example strong relatively jet of water.When second fluid for example contains full-bodied enrichedmaterial, just may need a kind of so strong relatively jet.Herein, because the strong relatively jet of first fluid, enrichedmaterial can dissolve well.Also be by this way, the strong relatively eddy current that appearance is formed by fluid in first blending box makes that Duo air is whipped in the beverage relatively when having the air admission opening.Therefore, best constriction constitutes the part of exchangeable reservoir.

Better storage space is retrained by removable wall at least partially, removable wall can move with respect to the remainder of storage space, make the moving of moveable part by wall, can change the volume of storage space, particularly storage space is retrained by the wall of making such as the movably flexible material of paillon foil at least in part.Particularly proportioner is provided with and is used at least one actuator of moveable part of moving end-wall herein, make that thereby reduce volume allots second fluid to blending box with batching mode, in particular for the compression storage space so that with batching mode second fluid is allotted to first blending box by compression.

Because storage space retrains by removable wall at least partially, the volume of storage space can be under a kind of help of the actuator that is used for allotting with batching mode second fluid to the first blending box and be reduced.The group of storage space and removable wall and actuator and constituted proportioner.

According to advanced person's embodiment, removable container is provided with a plurality of storage spaces that are separated from each other, and each storage space has been filled second fluid.First storage space has been filled for example coffee concentrate, and second storage space has been filled milk concentrates.By this way, when first fluid for example contains water, can generate coffee with milk.Particularly, each storage space is retrained by removable wall at least partially, removable wall can move with respect to the remainder of separately storage space, make the volume that can change corresponding storage space that moves of moveable part by wall, particularly each storage space is retrained by the wall of making such as the material of the flexible deformable of paillon foil at least partially, makes the volume that can change corresponding storage space that moves by outer wall.

According to preferential embodiment, proportioner is provided with a plurality of proportioners that with batching mode fluid are allotted to first blending box with several proportioners from mutually different storage space.

By this way, at first coffee concentrate can be allotted to first blending box from first storage space, and the liquid allocation device can be the liquid of for example hot water form for transporting to first blending box, with preparation coffee simultaneously.Subsequently, milk concentrates supplies to transport to first blending box from second storage space with batching mode, and hot water also is fed to first blending box simultaneously.Herein, when also having the air admission opening, air can be whipped into, so that obtain the milk of band foam.The milk of this band foam is allotted from exchangeable reservoir then.Therefore, work as coffee, when then being collected in the same cup with the milk of foam, just can prepare the good cappuccino (italian coffee) with white froth bed, described white froth bed is made by warm milk.

According to advanced person's embodiment, between each storage space on the side and first blending box on another side, have dividing plate, rise to particular value when above when be applied to pressure on the dividing plate by a kind of fluid, dividing plate will be opened.Especially, this is under the mutually different pressure, and at least some dividing plates will be opened.By this way, when each storage space during, thereby during with same force compresses, need only dividing plate and close by same actuator compression for example, this will cause the pressure in different storage spaces to equate that then pressure increases gradually when storage space is compressed.For example against each other and naturally constitute one when whole with flexible wall when storage space, above-mentioned situation is correct.Continue it, when the pressure in each storage space further rises, at first rise to the particular value that belongs to dividing plate separately when above when the pressure in each storage space, at least one dividing plate will be opened.At least some other dividing plates then will not opened yet.The result is that at least one the dividing plate place that at first opens, second fluid can flow out the arrival hybrid chamber, makes under the influence of liquid, to have generated beverage in first hybrid chamber.When continuation is compressed storage space, the pressure in described storage space will not rise usually, because the volume of a storage space reduces because of it becomes empty.Only when each storage space with opened closure became sky fully, the pressure in other storage space that its dividing plate is opened not yet just can further rise.Therefore in the moment after a while, at least one other dividing plate will be opened, and make that the second relevant fluid can be allotted to first blending box, to prepare different beverages from relevant storage space.By this way, at first for example can be made into coffee, then be milk, particularly with the milk of foam, and at first, coffee can be from the container of first blending box inflow such as cup, and the milk with foam after this can flow into the cup from first blending box, make it is that the foam of milk will float over above the coffee at least, cause the generation of tempting white cappuccino (italian coffee).

More at large, described system is configured to: use at least two different proportioners and allot fluid from least two storage spaces with mutually different flow velocity and/or during the mutually different cycle.Herein, again, proportioner can be independent of the fluid allocation device to be operated or Be Controlled.In other words, the first fluid and second fluid can have mutually different flow velocity and/or be allotted with controllable mode in the mutually different cycle.

But the part of air intake constitution equipment or container.Particularly at least one air intake is provided with the adjustable valve that is used to set the airshed size.Valve can be controlled by equipment and by customer's (manually).Valve for example can be set according to the form of the beverage that will prepare.Exchangeable reservoir for example can be provided with the code that is read by described equipment, the equipment that makes is known the beverage that will prepare which kind of form, and in this mode, equipment can for example be set adjustable valve and/or controlling liquid allocation device, with definite pressure, amount and temperature that for example is fed to the liquid of exchangeable reservoir.

Container according to the present invention is characterised in that container also is provided with: at least one first blending box; At least one flows out opening, and it is communicated with first blending box on fluid, to allot beverage from first blending box; Between the storage space and first blending box, be used for allotting at least one fluid communication of first fluid to first blending box; Enter opening with at least one, in use, it removably is connected in the outlet opening of fluid allocation device, so that second fluid is supplied to transport to first blending box; Storage space constitutes the part of proportioner at least in part simultaneously, and retrained by removable wall at least in part for this purpose, removable wall can move with respect to the remainder of storage space, the feasible volume that can reduce storage space that moves by removable wall, so that second fluid is allotted to first blending box from storage space with batching mode, in use first fluid also is fed to blending box under pressure simultaneously, make second fluid and first fluid mix and obtain beverage that beverage leaves container through flowing out opening then.

In Fig. 1, label 1 indicates the system that is used to prepare the predetermined amount of beverage that is suitable for consuming.System 1 is provided with exchangeable reservoir 2 and equipment 4, equipment 4 is provided with fluid allocation device 6 especially, fluid allocation device 6 is configured to allot the first fluid at least of an amount, all liquid in this way of first fluid and/or gas, all especially water in this way and/or steam under pressure.In this example, fluid allocation device dispenses water during use.

Exchangeable reservoir 2 is provided with at least one storage space 8, and storage space 8 is filled with second fluid such as beverage, enrichedmaterial or powder.In this example, relate to the enrichedmaterial that is used to prepare coffee.Container 2 also is provided with at least one first blending box 10 and at least one flows out opening 12, flows out opening 12 and is communicated with first blending box 10 on fluid.Container 2 also is provided with the fluid communication 14 between the storage space 8 and first blending box 10.In addition, container 2 also be provided with the outlet opening 18 that removably is connected in fluid allocation device 6 at least one enter opening 16.In Fig. 1 a, enter opening 16 and also be not connected in outlet opening 18.Yet this is the situation in Fig. 1 b.In this example, the opening that enters in Fig. 1 a is still closed by dividing plate, and dividing plate can be removed, all removable seals in this way.Flow out opening 12 and also keep this situation.In use, two removable seal can removing from outlet opening 18 can be connected to shown in Fig. 1 b and enter opening 16.

In this example, described system also is provided with choked flow piece 20, choked flow piece 20 is included in the fluid flow passages 21, fluid flow passages 22 through the outlet opening 18 of fluid allocation device 6, enter the opening 16 and first blending box 10, arrive from fluid allocation device 6 and flow out openings 12.

Particularly in this example, constriction 20 is included in the fluid flow passages 22, and fluid flow passages 22 enters opening 16 through the outlet opening 18 of fluid allocation device 6 and exchangeable reservoir 2, arrives first blending box 10 from fluid allocation device 6.In this example, storage space 8 is retrained by removable wall at least in part, and removable wall can move with respect to the remainder of storage space 8, makes to pass through moving of removable wall, can change the volume of storage space 8.In this example, storage space 8 is retrained by the flexible or deformable material such as paillon foil at least in part.In this example, the wall 9 of constraint storage space 8 is at least virtually completely made by the flexible material such as paillon foil.

By this way, storage space constitutes at least a portion of proportioner, as hereinafter will further stating.This batching assembling 24 also is provided with at least one actuator, and in this example, described actuator is compression set 26 forms, and compression set 26 is used to compress storage space 8, so that with batching mode second fluid is allotted to first blending box by compression.

In this example, compression set 26 is provided with two

compression element

28a, 28b, and in use they are positioned on two sides of storage space 8.

Compression element

28a,

28b utilize arm

30a and 30b to be connected in actuator 32.Equipment 4 also is provided with the control setup 34 that is used to control fluid allocation device 6 and actuator 32.Be control fluid allocation device 6 and actuator 32, control setup 34 produces for the control signal of transporting to fluid allocation device 6 and actuator 32

The work of the equipment of Miao Shuing is as follows before this.The purpose of the predetermined amount of beverage that is suitable for consuming for preparation, exchangeable reservoir 2 is placed in the equipment 4.Herein, the storage space 8 of exchangeable reservoir 2 is accommodated between two compression element 28a, the 28b.Also have, as shown in Fig. 1 b, outlet opening 18 is connected in and enters opening 16.Equipment is ready to for use now.For example by the button 36 by pressure control device 34, control setup 34 has caused beginning

transfer arm

30a, 30b on arrow P A and arrow P B direction respectively.Consequently

compression element

28a, 28b begin to compress storage space 8 thus.Herein, fluid communication 14 also is provided with dividing plate 38, but dividing plate 38 for example is breakable 38 forms, but breakable 38 tear owing to the pressure in the storage space 8 increases, pressure increases by compression storage space 8 and causes.In this example, consequently coffee concentrate will flow to first blending box 10 from storage space 8 through fluid communication 14 with batching mode.Meanwhile, control setup 34 has caused fluid allocation device 6 to activated.This causes 6 beginnings of fluid allocation device to allot first fluid under pressure, and first fluid is a water in this example.In this example, this water is temperature 80-98 ℃ hot water for example.This hot water flow to constriction 20 through liquid flow passageway.When arriving constriction 20, utilize constriction 20 to produce the jet of hot water.This jet is through outlet opening 18 and enter opening 16 and spray into first blending box 10.In first blending box 10, hot water will begin well to mix with enrichedmaterial.Herein, enrichedmaterial is controlled by the control of actuator 32 for the flow velocity of transporting to blending box.Flow velocity for the hot water of transporting to first blending box is also controlled by the control of convection cell allocation device by control setup.In first blending box 10, because the result of jet, enrichedmaterial will well mix with hot water, to make beverage.This beverage leaves and flows out opening 12 then, and for example is collected in the cup 40.Application is according to system of the present invention, owing to can be controlled well through the batching of after a while enrichedmaterial with through the batching both of after a while hot water, this just can guarantee: the concentration of a certain amount of enrichedmaterial in the beverage can accurately be determined.In addition, it can guarantee: during preparation leaving the beverage that flows out opening 12 is constant-quality, in other words, if desired, can be kept constant by the concentration of the enrichedmaterial among the beverage of allotting during allotting.In fact be: and if desired, be fed to the flow velocity of water of first blending box and the flow velocity of enrichedmaterial, each is Be Controlled independently of one another all.Therefore, more at large, it keeps: described system is configured to like this: fluid allocation device and proportioner can be independently of one another respectively for the defeated first fluid and second fluid to the first blending boxs.This needs: the value of first fluid flow velocity and first fluid by the time cycle during allotting be with the value of second rate of flow of fluid and second fluid by the time cycle during allotting irrelevant (being in this example under the control of control setup).

Proportioner relates to controlled and the actv. proportioner, and controlled and actv. proportioner is used for coming second fluid for transporting to first blending box by apply increased pressure or power to second fluid.Herein, the actv. proportioner is meant: owing to apply the excessive pressure or the result of power on the side of storage space, second fluid flows to first blending box by fluid communication from storage space.

In the present example, described system also is provided with air admission opening 42.Air admission opening 42 guarantees that air is fed to first blending box, makes that in use air is whipped in the beverage, to obtain beverage with fine-bubble froth layer.So, can obtain white coffee.In this example, in the downstream of constriction 20, air admission opening 42 is communicated with first blending box 10 on fluid.In this example, air admission opening 42 terminates in the fluid flow passages 22 through fluid communication 44.In this example, the part of air admission opening 42 and constriction 20 each difference constitution equipments 4.

After obtaining beverage, in this example, the coffee with fine-bubble froth layer is prepared to, and control setup 34 has turn-offed fluid allocation device 6.Control setup 34 also guarantees:

compression element

28a, 28b no longer move together, and separate and replace to move.Herein, can be like this: control setup at first causes the allocation of second fluid to the first blending box to be stopped, and after this, the confession of liquid is defeated to be stopped.So reduced the danger that second fluid for example pollutes constriction 20.

Fig. 1 c shows as

compression element

28a, 28b and moves on to together with storage space 8 crowded empty the time, this timed unit 34 will turn-off the confession of hot water to the first blending box and fail, and

arm

30a, 30b will no longer move on to together, move beginning to separate and replace, and make container take out in the slave unit once more then.

After this, the user can remove exchangeable reservoir, and if prepare the beverage of new quantity, just new exchangeable reservoir is put into equipment 4, and new exchangeable reservoir can be loaded onto the second multi-form fluid fully, all milk concentrates in this way.When under the help of new exchangeable reservoir, when having prepared milk, in the milk of preparation, will can not find the vestige of the drink form for preparing before this as the described similar fashion for preparing coffee based on coffee concentrate.The fact is: first blending box constitutes the part of exchangeable reservoir, and when new exchangeable reservoir is positioned in the equipment, also makes it is new all over, and therefore, first blending box of cleaning is placed in the container.Therefore, can not relate to pollution.

Now, with reference to figure 2a-2c, second embodiment according to system of the present invention has been described.In Fig. 2, has identical label herein, corresponding to the part of Fig. 1.

As be clear that serious difference is in Fig. 2 b and 2c: constriction 20 constitutes the part of exchangeable reservoir 2 now.In addition, can see that also air admission opening 42 constitutes the part of exchangeable reservoir 2.Herein, again, the air admission opening in constriction 20 downstreams is communicated with first blending box on fluid.In Fig. 1, first blending box is provided with and enters opening, extends to first blending box by entering opening fluid flow passages 22.In fact, this to enter opening be to be made of the opening that enters as container the opening 16.In Fig. 2 b, can see: container enter the opening that enters that opening 16 does not constitute first blending box 10.The fact is: constriction 20 has comprised the downstream that enters opening 16.As clearly seeing from Fig. 2 b, in the downstream of constriction 20, exchangeable reservoir is provided with elongated passageway 46, and therein in the downstream of constriction 20, at first, air intake 42 has stopped, and then is that the connectedness 40 of storage space 8 has stopped.The first actual blending box 10 in fact is arranged in the downstream of the constriction of passage 46.

Before it can be used, shown in Fig. 2 b, container can be provided with dividing plate 17, and dividing plate 17 has been closed and entered opening 16, yet this dividing plate can be removed.A kind of like this dividing plate can for example be a sealing member 17 movably.Container also is provided with closes the dividing plate that flows out opening 12, yet this dividing plate also can be removed.In this example, this dividing plate also is provided with removable sealing member 13.These movably sealing

member

13,17 remove by the user.Then, exchangeable reservoir is positioned in the equipment shown in Fig. 2 a.Enter the outlet opening 18 (in Fig. 2 a, this connection also is unrealized) that opening 16 is connected in fluid allocation device 6 then.Also have, shown in Fig. 2 a, storage space 8 again is arranged between two compression element 28a, the 28b.Again, user's pressing button 36 is with the preparation of starting beverage.Then, control setup 34 moves together actuator 32 holding arms 28a, 28b.The result is that as described above, storage space 8 is compressed.So, the storage space 8 formation proportioner that combines with compression set 26.Because

compression element

28a, 28b move together gradually, the pressure in storage space 8 will increase.The result is, but breakable 38 will tear thus, along with

compression element

28a, 28b further move together gradually, coffee concentrate will be with batching mode for transporting to first blending box 10.Control setup 34 also makes fluid allocation device 6 be started.Therefore, this will begin dispense hot water under pressure.This for example can be after the moment or some time that the fluid allocation device is still activateding, and the blending box of winning at first only is filled with enrichedmaterial, then also is filled with hot water.Hot water flow to container 2 through the outlet opening 18 of equipment 4.So hot water is fed to container 2 through entering opening 16 under pressure.Particularly, hot water longshore current body flow passage 22 flows on the direction of constriction 20.By this way, at constriction 20 places, form jet by hot water.This jet of hot water sprays on the direction of blending box 10 madial walls 48.Because air admission opening 42 is included in the downstream part of constriction 20, because the result of Venturi effect, air will be drawn into through air admission opening 42.Being drawn into air moves on the direction of madial wall 48 with jet.In first blending box 10, air and hot water will contact with enrichedmaterial.Because jet impulse on madial wall 48, has formed eddy current in first blending box, cause air, enrichedmaterial and hot water to mix, the mode of its mode and Fig. 1 system is suitable.So the beverage of making that stirs into air that has leaves first blending box through flowing out opening 12.So obtained to have the coffee extract of fine-bubble froth layer.When having obtained the beverage of aequum, control setup 34 has turn-offed the fluid allocation device, and control setup 34 also makes

arm

30a, 30b no longer move together, and stops to move together and replace, and then removes, but removes on the feasible container slave unit that uses.

The size of air admission opening 42 can be suitable for the form of the beverage that will prepare fully.If different containers is placed in the equipment, use the another kind of form beverage of its preparation example such as coffee, air intake then, the size of air intake can correspondingly be adjusted in other words.Be the milk based on milk concentrates preparation band foam, the size of air intake 42 can be for example greater than the size in the time will preparing coffee extract.For preparing other beverage, when not needing to stir into air wherein, air intake 42 can be removed.Also possible is: air intake 42 is provided with adjustable valve, and adjustable valve can for example be provided with to determine to be whipped into the amount of air in the beverage by the user.This valve also may be for example automatically to be set by equipment.Under the situation of for example Fig. 1, air intake 42 can be provided with the adjustable valve of representing briefly in the accompanying drawing 50.For determining that how adjusting described valve prepares beverage, exchangeable reservoir for example can be provided with the code that can read, and the code that can read for example is a bar code, or is stored in the code in the known responser own.Described equipment is provided with code reading device 52, and code reading device 52 utilizes signal wire (SW) 54 to be connected in control setup 34.Through code reading device 52, control setup 34 reads code, and code for example represents that valve 50 will set in which way.This code decides according to the form that is stored in second fluid in the container 2.If relate to milk concentrates, open greatlyyer when code for example can make the valve ratio have coffee concentrate.Like the complete class, when constituting containers a part of as the situation air intake among Fig. 2 a 42, equipment can be configured to also to be used for the adjustable valve 50 of control air inlet 42.Therefore some similar thing can be employed usually.Also have, the fluid allocation device can at random be allotted the variety classes first fluid such as steam or water.This selection for example can be gone to determine by readable code.If vessel filling enrichedmaterial, then for example hot water can be allotted by the fluid allocation device.Yet, if vessel filling such as the beverage of milk, the code of container can cause the fluid allocation device to allot steam, makes milk and vapor mixing in first Room, to obtain warm milk.

With reference to figure 3a-3c, the 3rd embodiment according to system of the present invention has been described briefly.Herein, the part corresponding to Fig. 1 and 2 has identical label.

With not existing together of Fig. 2 system be: current storage space 8 has different forms.In this example, storage space 8 is to be made by the top laminate 8a of flexibility and flexible base lamina 8b, and they along being connected to each other, form the leak free seam with its adjacent circumferential edge simultaneously.Each is for example to be made by the close paillon foil of liquid for the base lamina 8b of flexible top laminate 8a and flexibility.Base lamina 8b is provided with the opening that is communicated with fluid communication 14.But in fluid communication 14, again be provided with breakable 38 (not shown).Because replace the situation of the cylinder form among Fig. 1 and 2, now storage space 8 have different, have more disc shaped form, compression is put 26 and is had slightly different structure.As seeing in Fig. 3 a and 3b, compression set is provided with tabular compression element 28a and tabular compression element 28b now, and in use, member 28a is positioned at top laminate 8a top, and member 28b is positioned at the below of base lamina 8b.In tabular compression element 28b, be provided with slit opening 29, opening 29 guarantees that exchangeable reservoir 2 can slip in the equipment on the arrow P direction, shown in Fig. 3 b.Storage space 8 will end at the top of compression element 28b then, and first blending box 10, enter opening 16 and flow out the below that opening 12 ends at compression element 28b.29 paths that cause fluid communication 14 of slit opening.Also have, when container 2 when direction P slips into equipment, enter opening 16 and will be connected in outlet opening 18 in the close mode of liquid.In use, for allotting enrichedmaterial to the first blending box 10 with batching mode from storage space 8, now, compression element 28a will move down at the arrow directions X shown in Fig. 3 a.The result is that container 2 will be compressed in vertical direction, be first fluid to the first blending box 10 of enrichedmaterial so that allot in this example with batching mode.Described work also is quite analogous to the description of doing with reference to figure 2.

Current with reference to figure 4a and 4b, the 4th embodiment according to system of the present invention has been described briefly.Again, has identical label herein, corresponding to the part of Fig. 1 and 2.

The system of Fig. 4 a corresponds essentially to the system of Fig. 2 a at least.Difference is the form of first blending box., also be provided with path 46 herein, path 46 for example arrives outflow opening 12 from entering opening 16.In this path 46 of a part that constitutes the fluid flow passages of mentioning previously 22,, air admission opening 42 has stopped through fluid communication 44.Fluid communication 14 also ends in this passage 46.End at the downstream of the position 56 in the passage 46 in fluid communication 14, in fact in this passage, formed first blending box 10.In first blending box 10, contain jet impact element 58.Therefore jet impact element 58 is located in first blending box 10 and (sees Fig. 4 a and 4b).The sensing of constriction 20 is relevant with jet impact element 58, so in use, the jet impulse that is produced by current limiting element 20 is on jet impact element 58.Because the impact of jet on jet impact element, liquid is atomized.Utilize jet simultaneously, air will be drawn into by air admission opening 42.Also have, the enrichedmaterial in proportioner 24 is fed to first blending box 10 with batching mode.In first blending box 10, hot water and extract mix well.Because jet impulse is on jet impact element, jet further is atomized, and air can be whipped in well.Then, so make and have the beverage that stirs into air and leave first blending box 10 through flowing out opening 12.Herein, but beverage diffraction stream impact components flow to and flow out opening 12.The further work of equipment can be according to the description of doing with reference to previous each accompanying drawing.

Currently the 5th embodiment according to system of the present invention has been described with reference to figure 5a and 5b.

In this example, container corresponds essentially to reference to figure 1 described.Yet current its maintenance: exchangeable reservoir is provided with a plurality of

storage space

8a and 8b, is two separated storage spaces in this example.In this example, for realizing this situation, as shown in Fig. 5 a.Storage space 8a utilizes flexible partition wall 60 to separate flexible partition wall 60 all paillon foils in this way mutually with storage space 8b.Therefore,

storage space

8a, 8b comprise the continuous flexible outer wall 62 (seeing Fig. 5 b) such as paillon foil, and it has sealed by madial wall 60 spaces divided into two parts (seeing Fig. 5 b).The first storage space 8a ends in first blending box 10 through first fluid connectedness 14a.The second storage space 8b ends in first blending box 10 through fluid communication 14b.The second storage space 8b ends in first blending box 10 through the second fluid communication 14b.Fluid communication 14a contains through-flow openings 64a, (sees Fig. 5 a) and fluid communication 14b contains through-flow openings 64b.To point out: for the purpose of clear, in Fig. 5 a, do not comprise all labels that comprised among Fig. 1 a herein.The work of described equipment is as follows.

Be quite analogous to as described abovely,, enter opening 16 and flow out opening 12 and be cleaned by removing the sealing member of mentioning previously.After this, container 2 can be placed in the equipment 4.Enter opening 16 then and be connected in outlet opening 18 in the close mode of liquid.The user begins beverage preparation by pressing button 38.The result is, is quite analogous to as described abovely, and control setup 34 causes fluid allocation device 6 to be started, and to allot first fluid under pressure, first fluid is a hot water in the present example.So, under helping, constriction 20 produced jet, and this jet sprays in first blending box 10.Control setup 34 also makes compression element 28a, 28b move together.In this example, again, but fluid communication 14a closed by breakable 38a, but and fluid communication 14b is closed by breakable 38b.Be quite analogous to as described abovely, the outer side edges of storage space 8a, 8b will be pressed together along 62.The result is pressure at storage space 8a and begins to rise in storage space 8b.Herein, but breakable 38a, 38b can be configured to like this: at first, but opening for example owing to breakable 38a than thin structure.Then, if storage space 8a fills with coffee concentrate, at first, coffee concentrate will be fed to first blending box.So, at first made the coffee that leaves blending box through outflow opening 12.When compression element 28a, 28b further move to a time-out, the pressure among the storage space 8b will can further not rise significantly, because storage space 8a is emptied at leisure.Only as storage space 8a inanition at least in fact, make all coffee concentrates disappear from storage space 8a and also be used to prepare coffee, then, when compression element 28a, 28b are further moved on to a time-out, but but the second breakable 38b that for example is slightly thicker than the first breakable 38a will be torn.This means: only when all coffee concentrates at least in fact when storage space 8a is allotted to first blending box, will be fed to first blending box with batching mode from the fluid of storage space 8b.Fluid among the storage space 8b for example can contain milk concentrates.Consequently: then, when hot water is fed, produced milk at first blending box.In addition, because air admission opening 42 will generate the milk of band foam.Then, the milk of this band foam will be parked in the top that has been present in the coffee extract in the cup 40, and the band foam segment of milk will float over its top.So, obtained perfect cappuccino (italian coffee).

In addition, can imagine other modification.For example, through-flow openings 64a can be designed to greater than through-flow openings 64b.For example in the time can tearing film 38a and 38b and open really under similar pressure, and therefore will at least in fact side by side open in this case, then, when outer wall 62 is compressed, at first, the pressure among storage space 8a and the 8b will rise to equal extent.Therefore, when two can be torn that film 38a, 38b are approximate side by side to break, coffee concentrate will be via through-flow openings 64a from storage space 8a for transporting to first blending box 10.Meanwhile, milk concentrates will be from storage space 8b for transporting to first blending box 10.Two kinds of enrichedmaterials will mix with hot water jets, and hot water jets supplies to transport to first blending box 10 by fluid allocation device 6.So, made the beverage that contains coffee and milk, and when beverage is collected in when opening 12 leaves first blending box 10 in the band handle cup 40 through flowing out, yet, because the surface ratio through-flow openings 64b's that in this example through-flow openings 64a has is much bigger, will be when initial for the flow velocity of the coffee concentrate of transporting to first blending box greater than flow velocity for the milk concentrates that transport to first blending box 10.The result is: because the volume of storage space 8a is approximately equal to the volume of storage space 8b in this example, make storage space 8a at first become empty.When storage space 8a is hollow, and storage space 8b then, only is that milk concentrates will be fed to first blending box 10 when hollow yet.The result is, only will make the milk of band foam, the milk of band foam be parked in the coffee that is contained in the band handle cup 40 above.Again, the milk of this band foam will float over the top of coffee and form beautiful white froth bed.So, make cappuccino (italian coffee) once more.

Also possible is that through-flow openings 64a for example has similar size to through-flow openings 64b.It can be like this: for example the volume of storage space 8a is less than the volume of storage space 8b.Herein, it also can cause: the coffee concentrate in storage space 8a is much strong, has higher concentration than the milk concentrates among the storage space 8b in other words.Because through-

flow openings

64a, 64b are generally big approx, when initial, the flow velocity of coffee concentrate will equate approx with the flow velocity of milk concentrates.Departure point herein is: two kinds of enrichedmaterials have identical viscosity.The result is that storage space 8a will earlier become empty than storage space 8b.This means: when storage space 8a is hollow, only be that milk concentrates is fed to first blending box from storage space 8b, make that again, coffee and milk have only been made milk after this in first blending box after blending box is made into when initial.So, again obtained cappuccino (italian coffee).

Yet might be: storage space 8a equates approx with the volume of storage space 8b.Through-flow openings 64a also equates with the size of 64b.Yet the viscosity that has caused coffee concentrate now is less than milk concentrates.The result is, when compression outer wall 62, it again keeps: from the flow velocity of the coffee concentrate of storage space 8a greater than flow velocity from the milk concentrates of storage space 8b.The result is that it again keeps: when initial, coffee concentrate and milk concentrates are fed to first blending box 10, so made coffee, coffee leaves first blending box and ends in the container 40 through outflow opening 12.After spending some times, when storage space 8a is at least in fact hollow, and milk concentrates will not be in this situation.After all, milk concentrates is more viscous, so flow velocity is lower.Here it is, and why this has only milk concentrates will be fed to blending box 10 afterwards at least substantially, so made the milk of band foam at least basically, it again ends on the top that has had the coffee in the container 40, makes again to make cappuccino (italian coffee).This modification is understood all to be fallen in the framework of the present invention.

With reference to figure 6a and 6b the 6th embodiment according to system of the present invention has been described.Again, the system of Fig. 6 a and 6b corresponds essentially to the system of Fig. 1 at least.What also will explain briefly only is difference to the system of Fig. 1 herein.

For the system of Fig. 6, exchangeable reservoir is provided with a plurality of storage space 8a and 8b, is two storage spaces that are separated from each other in this example equally, and each storage space is filled with fluid.In this example, storage space 8a again fills with coffee concentrate, and storage space 8b fills with milk concentrates.In this example, each storage space 8a and 8b are equal to the storage space of being discussed with reference to figure 18 at least basically.Therefore they are actually distinct storage space at least, also do not relate to the connecting wall of situation as shown in Figure 5 simultaneously.Storage space 8a ends in first blending box 10 through fluid communication 14a.Storage space 8b ends in first blending box 10 through fluid communication 14b.Again, it also keeps: but fluid communication 14a closed by breakable 38a, but and fluid communication 14b is closed by breakable 38b.As can be seen in FIG., fluid communication 14a and 14b end in the bonded assembly outflow opening 66 together.This bottom side of flowing out opening is shown among Fig. 6 b.But what substitute breakable 38a and 38b is, but each fluid communication 14a, 14b also will be provided with a breakable 38, flows out opening 66 to close to connect.Yet, in this example, be not this situation.As seeing from Fig. 6 a, the first storage space 8a is between two compression element 28a and 28b.The second storage space 8b is between two compression element 28b and 28c.Compression element 28a, 28b, 28c are connected to actuator 32 through arm 30a and 30c.Actuator 32 can make arm 30a move on the direction of arm 30b, makes storage space 8a by crowded empty lentamente.Therefore, actuator 32 can make arm 30c move on the direction of arm 30b independently, with crowded empty storage space 8b little by little.By this way, described system in fact is provided with a plurality of proportioners, to compress mutually different storage space 8a and 8b by different proportioners.

By this way, might with mutually different speed and/or during the different mutually cycles crowded empty storage space 8a and 8b.For example, be the preparation beverage, at first, can be fed to first blending box from the enrichedmaterial of storage space 8a, then the enrichedmaterial from storage space 8b can be fed to first blending box.The result is, for example at first, made coffee at first blending box, then is to have made milk., also have, air intake can comprise above-mentioned valve 50 herein.When entering opening 16 and be connected to each other in the close mode of liquid with outlet opening 18, code reading device 52 reads for example code.This code 52 comprises fluid form that the first storage space 8a and the second storage space 8b fill respectively for information about, and fluid is respectively coffee concentrate and milk concentrates in this example.Therefore, if container is to be used for preparing cappuccino (italian coffee), control setup 34 can be guaranteed to do like this based on the code of reading.For this purpose, for example when button 36 is again depressed, control setup at first will make compression element 28a begin to move on the direction of compression element 28b by actuator 32.The result is that at first, coffee concentrate will be fed to blending box 10 from storage space 8a.Simultaneously, control setup 34 for example can cause air intake valve 50 to be closed.When air intake valve 50 has cut out, and under the help of fluid allocation device 6, hot water under pressure, be fed to constriction 20 (meanwhile or coffee concentrate just begun the batching after), produced water jet, and do not had air to be drawn into through air admission opening 42.Hot water will mix with coffee extract, and be not have air to be whipped into coffee basically at least.At first, through flowing out opening 12, coffee extract will be allotted, and does not have fine-bubble froth layer.After some times, as storage space 8a when being in fact hollow at least, control setup 34 will cause compression element 28c to move on the direction of compression element 28b subsequently.The result is that the second storage space 8b is emptied lentamente.So milk concentrates is fed to first blending box 10.Now, control setup 34 can cause choker relief valve 50 to be opened.The result is, the hot water jets that under constriction 20 helps, produces air along valve 50 suction first blending box.By this way, made at first blending box and had the milk that stirs into air.This milk contains fine-bubble froth layer.After this, when milk supplies to transport to coffee extract through flowing out opening 12, the milk of band foam will float over above the coffee extract, so make cappuccino (italian coffee) once more.When storage space 8a be hollow and after storage space 8b when being emptied, the fluid allocation device can continue dispense hot water.Switch to when allotting milk concentrates when having finished from allotting coffee concentrate, allocation device also can temporarily be stopped.

Shown according to a seventh embodiment of the invention at Fig. 7 a and 7b.The embodiment of Fig. 7 a and 7b corresponds essentially to the embodiment of Fig. 6 a and 6b.Hereinafter only difference will be described.In the embodiment of Fig. 7 a and 7b, as above-outlined embodiment did, it keeps: each storage space is made by removable wall at least in part, removable wall can move with respect to the remainder of separately storage space, make and pass through moving of wall, can change the volume of each storage space.In this example, storage space 8a and 8b constitute (also seeing Fig. 7 c) by cylindrical outer wall 78 and bonded assembly, the rigid partition wall 80 of rigidity.Storage space 8a also is provided with movably rigid walls 82, and storage space 8b is provided with movably rigid walls 84.Removable wall 82 can move with respect to the remainder of separately storage space 8a.It also keeps: removable wall 84 can move with respect to the remainder of storage space 8b.Proportioner 24 is provided with first actuator, and first actuator contains bar 85 and moves down the actuator 32 of bar 85.When moving down, bar 85 will contact wall 82, then begin to press wall 82, and it is moved down, and make the volume of storage space 8a be reduced, so that allot second fluid be present among the storage space 8a with batching mode.Proportioner 24 also is provided with second actuator, and second actuator contains bar 86 and moves down the actuator 32 of bar 86, makes that it will contact wall 84, to move down wall 84 when bar 86 moves down.If wall 84 moves down, the volume of the second storage space 8b is reduced, to allot second fluid to the first blending box from second storage space.The work of Fig. 7 equipment also is quite analogous to the work with reference to figure 6a and 6b description.In this example, bar 85 can be independent of bar 86 and upwards and move down.From first storage space with from therefore Be Controlled independently of each other of the batching of second storage space.This relates to flow velocity and time/cycle two aspects, and they can reciprocally change to allot fluid from two storage spaces.

Also can imagine: bar 85 and 86 is connected to each other by transverse arm 88, and this transverse arm 88 utilizes bar 90 to be connected in actuator 32.In this case, all these requirements: wall 82 and wall 84 are driven by same actuator.86 on bar also can for example be longer than bar 85, make when bar 85 and 86 moves down simultaneously, wall 84 at first moves down beginning, make and for example begin when initial to allot milk concentrates from storage space 8b, and only after this, when wall 84 has moved down slightly, bar 85 will contact wall 82, make wall 82 also will move down with wall 84 then.Carve thenceforth, coffee concentrate also is fed to first blending box from storage space 8a.The result is, at first, only is that milk concentrates is fed to first blending box, makes only to have prepared milk when initial, and milk is fed to container 40.After this, the coffee with milk is fed to container 40.So it is described above once more, in addition ought be in any case only milk concentrates be fed to during the first blending box cycle, the air admission opening is opened, and air is whipped in the milk, make that the milk of band foam is allotted, can make good cappuccino (italian coffee).In fact, at first only be that the milk of band foam is allotted, and this coffee (when the air admission opening is still opened, randomly having foam) that has milk is afterwards allotted.

Shown removable wall 9 in Fig. 9, removable wall 9 has retrained at least a portion of at least one storage space, and removable wall 9 can be made by deformable or flexible material such as flexible plastic.Herein, removable wall also can have the structure of flexible shape, makes it to be compressed in the direction of arrow Z (see figure 9), so that allot fluid with batching mode.For this purpose, system is provided with bar 24, and bar 24 can drive actuator 32 being directed downwards water of compaction plain wall section 9 of arrow Z, makes vertical wall segments " fold ".

The system of Figure 10 is hereinafter described corresponding to the system of Fig. 1 to a great extent.Hereinafter, with the difference that further specifies between the system of the system of Fig. 1 and Figure 10.

Shown that in Figure 10 also being provided with second blending box, 100, the second blending boxs 100 according to system of the present invention has constituted first blending box 10 and flowed out fluid communication between the opening 12.Outflow opening 12 is positioned at the bottom 102 of second blending box 100.Second blending box 100 has constituted the part of exchangeable reservoir 2.

In this example, it has also kept: described system also is provided with the constriction 20 that is included in the fluid flow passages 21, fluid flow passages 21 through outlet opening 18, enter opening 16 and first blending box 10 (with in this example, also through second blending box 100), arrive outflow opening 12 from fluid allocation device 6.In this example, constriction 20 is arranged in fluid communication 104, and fluid communication 104 is between first blending box 10 and second blending box 100.Constriction 20 is designed to like this: in use, use the jet that constriction has produced beverage.The jet of beverage sprays in second blending box 100.In this example, described system also is provided with the air admission opening of air for beverage in the input system.

In this example, air ends in the fluid flow passages 21 through fluid communication 44, constriction 20 downstreams and second blending box, 100 upstreams for defeated opening 42 and (ends in the fluid communication 104 in this example).

The work of described system is as follows.Be quite analogous to situation about discussing with Fig. 1, at first, removable dividing plate will be removed, and container will be connected in equipment.By pressing button 36, control setup 34 will make proportioner 24 begin to allot in second fluid to the first blending box 10.Simultaneously or after very fast, control setup 34 guarantees that 6 beginnings of fluid allocation devices allot first fluid to the first blending box under pressure.In first blending box, the first fluid and second fluid will mix, to make beverage.First blending box 10 will be filled with beverage gradually.When first blending box is filled, however, proportioner continues to supply defeated second fluid to the first blending box 10 under pressure, and the fluid allocation device continues under pressure for defeated first fluid, pressure in first blending box will rise, and make beverage extrude first blending box 10 by constriction 20.The result is, uses constriction 20 and produced beverage jet, and beverage jet sprays in second blending box 100.Also have, because Venturi effect, air will be drawn into through air admission opening 42.This air also flows to second blending box 100.

In second blending box 100, jet will impact on bottom 102 to stir into air.Beverage and air will mix, and make air be whipped in the beverage.Having the beverage that stirs into air flows out through flowing out opening 12 from second blending box 100 as the beverage with fine-bubble froth layer then.

In second blending box 100, also can comprise other jet impact element 106 (in Figure 10, showing) with dotted line, and constriction 20 is arranged like this with respect to jet impact element 106: in the use, as discussed in reference to Figure 4, jet impulse on impact components so that air is stirred in the beverage.Be quite analogous to as described abovely, when not needing to stir into air, air admission opening 42 can be closed or save.

Each embodiment of attention: Fig. 1-9 is discussed as reference Figure 10, can be provided with second blending box 100.

In addition, use the equipment of Figure 10, air admission opening 42 also can for example be arranged to as shown in Figure 1.Air is drawn into and supplies to transport to first fluid then.Via first fluid, then air admission first blending box and will with the beverage blends that obtains at this place.The jet that makes with constriction 20 also will comprise air then.Jet in second blending box again will be made the beverage with fine-bubble froth layer after impacting.

In the example that above provides, use proportioner and can be allotted to first blending box at following second fluid of pressure.The result is that in the embodiment of Figure 10, beverage can not reflux and enter storage space 8.Also can imagine: proportioner relates to the active proportioner that utilizes pump to allot second fluid.

In the embodiment of each general introduction, first fluid can contain the gas such as steam.Under such a case, second fluid will often contain beverage, for example be the described beverage of heating, and the gas of first blending box 10 is inserted to described beverage.Gas also can contain carbon dioxide (CO ₂) to obtain soda.Also have, first fluid can contain liquids and gases.

In each embodiment of Fig. 1-10, constriction also can be removed.Yet first and/or second fluid must be for transporting to first blending box 10, so that first and second fluid will mix well under enough big flow velocity.Also have, according to the present invention, constriction can be designed to like this: use constriction and produce mist vapour.According to the modification of Fig. 1-9, this need produce the mist vapour of first fluid in first Room.For this purpose, constriction can be made by the rubber with " running through for defeated " opening, and when supplying to fail first fluid, its diameter is very trickle, with the atomizing first fluid.The first fluid and second fluid of atomizing mix, and have obtained to have the beverage that stirs into air thus.Beverage and fine-bubble froth layer are left first Room then.If beverage comprises big relatively air foam, this can stop by the size of regulating the outflow opening or smash.Macrofoam for example may can't pass the outflow opening, is allotted so have the beverage of fine-bubble froth layer.According to the distortion of Figure 10, this need produce the mist vapour of beverage in second Room 100.The result is that air is whipped in the beverage.Have the beverage that stirs into air then and leave second Room.Then as described above, the beverage with fine-bubble froth layer flows out from container through flowing out opening.

In the embodiment of above-outlined, first fluid is fed to first blending box in period 1 at least, and second fluid is fed to first blending box in second round.

Herein, first and second cycle can begin at one time, and finishes in the same time.Also may be to begin after a while than the period 1 second round.Yet other variation also is possible.

In addition, fluid allocation device 6 can be configured to allot arbitrarily multi-form first fluid, such as steam, water, CO ₂Deng.Again, selection in view of the above can be controlled by control setup 34, and will often be the form that meets second fluid in first fluid or the exchangeable reservoir.Also have, if desired, this selection can be set mutually or determine under the help of code reading device 52.

The present invention is not limited to any way to the embodiment of above-outlined.In the embodiment of Fig. 5, storage space is arranged to each other side by side.Also possible is: storage space is lined up one above another, as the simple demonstration of Fig. 8 a and 8b institute.According to the embodiment of Fig. 6 a, constriction and air admission opening belong to container (part), and the situation among this and Fig. 1 is opposite.Nature also is in Fig. 6 a, and constriction and/or air intake can be fixedly connected to equipment.In the present example, storage space is filled with coffee concentrate and/or milk concentrates.Based on or also can not imagine based on other fluid of enrichedmaterial, for example can consider to be used to prepare the fruit juice of lemonade herein.Equipment yet can be provided with additional storage space, and they are filled with the additive such as soluble powder or enrichedmaterial.These powder for example also can be added into first blending box by each storage space of crowded empty.For example relate to delicious intensifier, sugar, cocoa and analogue herein.Also have, may relate to milk powder and/or cream.Usually, it keeps: as substituting of enrichedmaterial, also can add the things such as powder that dissolve in such as the liquid of water.This modification is understood that to fall in the framework of the present invention.The temperature of first fluid can change.For example, first fluid can be made up of the water or the cold water of room temperature.Also have, after a period of time, also can change for transporting to the temperature that container is used to prepare the first fluid of beverage.As tearing substituting of film, dividing plate 38 can comprise by device manipulation, that will be opened, known valve own.Also can realize the crowded empty storage space in a different manner, such as crowded empty under the help of the power that produces by air pressure.Successively, this power can act on the outside of storage space.Dividing plate 17 also can be to be different from the structure that can remove sealing member.For example, dividing plate can be provided with by hand or by the valve of device manipulation.Dividing plate also can be made by tearing film, can tear film in blending box fluid mixture and the influence of liquid under torn.
