Before being inserted into housing 12, container 54 can be airtight so that food wherein is by body 54a and lid Sub- 54b completely around.However, once container 54 is properly inserted into drawer 16 and drawer 16 is properly inserted into In housing 12, then formed preferably in container 54 or there are the hole that at least two separate.First hole 43 by pierce through or The discharge port 42 being inserted into lid 54b exists or at the discharge port 42.Thus, the first hole 43 is preferably formed in In the upper end of container 54.The first hole 43 can be formed by moving container 54 relative to generally fixed discharge port 42.So And can be by forming the first hole 43 relative to fixed container 54 can be kept to move discharge port 42.The width in the first hole 43 Degree or diameter are preferably about the same with the width or diameter of discharge port 42, to be carried between the first hole 43 and discharge port 42 For close fitting.As described in detail later, exist in body 54a or form the second hole 45.Second hole 35 preferably forms Be positioned in the lower end of container 54 or near, and be vertically formed or be positioned at below the food in container 54.Can be Container 54 is properly inserted into during drawer 16 and/or forms second after container 54 is properly inserted into drawer 16 Hole 45.However, the food in container 54 is used as the restriction in discharge port 42.

Mean that this electric appliance operates in pattern of pressure there are limitation in exit.That is, when container 54 is with discharge port In the presence of limitation on 42, the first holder 26, HWG32, the second holder 40, fluid path/conduit 50 and container 54 are preferred Ground forms at least substantially closed system.The part of at least a portion of HWG32, such as path 38, preferably system Lowermost portion.At least a portion of 50 or first holder 26 of conduit can be the highest part of system.

By the discharge port 42 at least partially defined, this system is configured to realize with being remained above the interior of atmospheric pressure Portion's pressure.Especially, when starting or HWG32 is powered, at least one of temperature of the liquid in system starts to increase. This is turn increases the internal pressure in system.In other words, by constant volume, increasing the temperature of system makes the pressure of system Power increase.Although discharge port 42 is at least partially defined at ambient pressure, the path of minimum drag and it is Only outlet pathway.The liquid that foregoing phase transformation in HWG is realized in HWG32 is moved to the second holder (under stress) 40, by discharge port 42 and into container 54 to prepare beverage.

Since HWG32 continues to heat and fluid is flow to from the path 38 of HWG32 in the second holder 40, Heating fluid under pressure is guided towards discharge port 42 and is directed in discharge port.Fluid is heated preferably in pressure Under flow through discharge port 42, and enter in container 54 to be contacted with food wherein.Food in container 54 It is relatively low by the flow restriction of container 54 during the initial wetting of thing.However, since the food in container 54 becomes little by little It is impregnated with, the flowing limitation of food increases and liquid is slowed down by the flowing of discharge port 42.Thus, the stream of container 54 is passed through Speed is initially supplied to less than HWG32's.Pressure in the electric appliance 10 including the second holder 40 further increases.

When the pressure rating in the second holder 40 starts increase, at least one of fluid (that is, liquid or steam) Lease making enters the first holder 26 from the opening between such as the second holder or the fluid path of conduit 50 to reversion.Thus, Any pressure difference reduction or equal between second holder 40 and the first holder 26.In the first holder 26 and the second holder Fluid loops back to or " recycling " occurs to the beginning of system by making for pressure equilibrium in 40.It is flat in whole system Equal pressure increase.

When the first holder 26 and the second holder 40 are maintained at substantially equal internal pressure, the first holder 26 Interior liquid can flow through inlet non-return valve 58 and into HWG32.In some embodiments of kitchen appliance 10, by In " recycling " of fluid, the fluid into HWG32 is in than being initially brought into the liquid of HWG32 when the operation cycle starts more At high temperature.In this way, fluid is transformed into gas more quickly in HWG32.This can increase to the stream of the second holder 40 Speed.The cycle increase of pressure, and fluid flowing continues in this system and finally promotes substantially all stream under stress Body is by container 54 and into vessel 15.Although the first holder 26 and the second holder 40 preferably extend through pattern of pressure guarantor Hold under roughly the same internal pressure, but this internal pressure is preferably higher than ambient pressure, and it is used as motivator So that the heating liquid in the second holder 40 is moved through/crosses in container 54 limitation of food and into vessel 15. In the case that the first holder 26 that may such as do not lack in traditional ADC is balanced with the pressure before the second holder 40, Inlet non-return valve 58 cannot be opened, and until HWG32 " boiling dry " and disable, or the pressure on the upstream side of HWG32 is another Dissipate in other places.HWG32 cannot be refilled during brew cycle referred to as " suspend " and brew or heating cycle.Such as pass through container 54 back pressures formed, may pause tradition ADC.ADC pauses are further illustrated below.

As shown in Figure 2 A, pressure-relief valve 44 and/or single vacuum release valve 46 can be positioned at the second holder 40 In roof or near it.Valve 44,46 can be spring-loaded, umbrella-type etc..Pressure-relief valve 44 is preferably biased into closure, and excellent Selection of land is opened when the pressure in the second holder 40 reaches predetermined value.Pressure-relief valve 44 can prevent the overvoltage of discharge port 42. As described in detail later, vacuum release valve 46 is preferably biased into closure, and preferably and if when the second holder 40 are internally formed vacuum or are opened when internal pressure drops to below atmospheric pressure.Discharge check valve (it is not shown, but referring to It is following and figure 3 illustrates discharge check valve 266) can be positioned in the second holder 40 near discharge port 42.

During by normal burst caused by HWG32, the fluid of heating is from closed-system (for example, passing through container 54 And enter in vessel 15) it is mobile, this results in the gap of generation negative pressure.In addition gas when wherein is begun to cool down or When ground is converted into liquid, vacuum can be formed in the second holder 40.Negative pressure or vacuum can by discharge port 42 and/or Vacuum release valve 46 discharges.It is important that prevent negative pressure from reaching discharge port 42, because negative pressure can lead to food from container 54 Discharge port 42 is crossed to pull in upward into the second holder 40.When the pressure in the second holder 40 for timing (that is, be equal to or More than air), vacuum release valve 46 preferably closes.Vacuum release valve 46 can be positioned at wherein gas and be easiest to and/or lead to The place often condensed.For example, vacuum release valve 46 can be positioned near the HWG32 that gas is initially formed, or wherein not It is expected near the discharge port 42 of vacuum.

In operation, liquid is preferably initially incorporated into the first holder 26, and since gravity is flowed into HWG32 In and be possibly flowed into a part for tedge 56.Liquid preferably stops flowing when equilibrium is reached so that the The height of liquid in one holder 26 at least generally, is inaccurately equal to liquid in the downstream of tedge 56 and/or HWG32 The height of body.After HWG32 is started, at least a portion liquid in system is preferably heated and is converted into gas.Gas Body is flowed ultimately into the second holder 40 with liquid.Liquid continues flow through discharge port 42 and flows in container 54. At certain saturation point of food in container 54, the fluid in the second holder 40 can flow while around HWG32 By the first holder 26, the loop for recirculated fluid is consequently formed.The pressure equilibrium of formation is by more liquid from One holder 26 is pushed into HWG32 or additionally makes pressure equal, so that inlet non-return valve 58 can be opened.Thus, it is Fluid in system advances up to the operation cycle along automatic adjustment path to be terminated, at this moment any back of the body as caused by being impregnated with food Pressure is all overcome by increased pressure in system.Conclusively, the combination of the fluid and food in container 54 is flowed into vessel 15 Drunk for user.Once the combination of the liquid of injection and the desired amount of food is flowed into vessel 15, HWG32 is with regard to preferred Ground automatically disables (for example, cut-out) and this operation cycle completes.

In traditional ADC, the internal pressure on the upstream side and downstream of HWG32 is unequal.As noted above, i.e., Make the relatively low back pressure on the downstream fluid path from HWG HWG may also be caused to suspend.During HWG " pause ", Pressure in HWG exceedes the pressure of inlet non-return valve upstream, so that check-valves opens delay.This delays causing HWG to become to compare It is desirably hotter.When pressure is finally discharged and liquid begins to flow into HWG, liquid flickering wherein is into gas. Before liquid is suitably filled with HWG, inlet non-return valve is prematurely closed with the relevant increased pressure of gas blast.This is slow Cycle will repeat, until whole liquid are all largely evaporated to its exterior.Container disclosed in theme, which is formed, may suspend ADC Back pressure.The novel structure of theme kitchen appliance 10 is that it allows back pressure in the case where not suspending HWG32.

Kitchen appliance 10 is operated in pattern of pressure to be included container 54 being arranged in pull to prepare the method for optimizing of beverage In part 16, and drawer 16 is suitably attached and/or is inserted into housing 12.Container 54 can include working as discharge port 42 Pierce through lid 54a and top-portion apertures that while extending in container 54 is formed in container 54 or the first hole 43.Preferably work as container 54 when being inserted at least a portion of drawer 16, can exist in the body 54b of container 54 or form the second hole 45.By This forms the flow path from the 43 to the second hole of the first hole 45 by container 54.First holder 26 fill at least in part with Liquid, then it is flowed into HWG32.When starting HWG32, the internal pressure of system and the temperature increase of liquid.Conclusively, Gas is produced, it makes heating liquid be moved under stress in the second holder 40 and arrives discharge end by the second holder 40 Mouth 42 and entrance container 54.When fluid (that is, liquid and gas) enters the second holder 40, labyrinthine pathway (not shown) It can be used for separating liquid and gas.When the food in container 54 is saturated, the back pressure increase in the second holder 40.It is logical Cross continue operate HWG32 overcome this back pressure so that the internal pressure of system increases to level more than back pressure.At this moment, it is hot Liquid is pushed through container 54 and into vessel 15 to be drunk by user under stress.

, can be by the way that container 454 be moved into engaging and in container with fixed discharge port 442 with reference to Figure 14 A- Figure 14 F The first hole 443 is formed in 454 lid 454b.Especially, at least one four joint element for bar 490 is preferably removable by funnel 472 Drawer 468 is attached to dynamicly.Four joint element for bar 490 can be positioned at each of two opposite sides in sleeve retainer funnel On.Especially, parallel bar 490a, 490b that at least two of each four joint element for bar 490 separate are positioned at funnel 472 and pull Between part 468 and be operably connected funnel 472 and drawer 468.The first end of each bar 490a, 490b or upper end are preferably Funnel 472 pivotally is attached near the first upper end 472b of funnel 472.The second end of each bar 490a, 490b or lower end Preferably the inner surface of drawer 468 is attached pivotally in the lower end of drawer 468.As described in detail later, when When drawer component 416 is properly inserted into housing 412 and funnel 472 is properly inserted into drawer 468, four bars connect Fitting 490 realizes funnel 472 relative to the upward movement of drawer 468, to cause discharge port 442 to pierce through container 454 Lid 454b is to form the first hole 443.

As shown in Figure 14 A- Figure 14 F, when drawer component 416 is initially inserted into housing 412, drawer 468 Flatly or with support surface moved generally in parallel with funnel 472.However, when drawer component 416 upcountry moves When enough or preset distance is into housing 412, the part of the inward portion of funnel 472 preferably with the inside of housing 412 connects Touch.The contact with the inside of housing 412 of funnel 472 causes four joint element for bar 490 that are moved horizontally through of funnel 472 to be converted into erecting Translation is moved.Especially, when drawer 468 continues to be horizontally moved into the inside of housing 412, funnel 472 starts at least portion Ground is divided to move upward.Funnel 472 preferably moves enough distances upward so that discharge port 442 pierces through container 454 Lid 454b, to form the first hole 443 and surround at least one of close of discharge port 442 at least slightly pressing Sealing 482.

With reference to Figure 14 A and Figure 14 F, container 454 is supported in funnel 472 via sleeve retainer 475.Protuberance 492 is excellent Selection of land is down extended in the inside of housing 412 and/or into recess 414.Complementary slot or opening 493 are preferably formed in In at least a portion of sleeve retainer 475.The combination of protuberance 492 and opening 493 is it is preferred to ensure that container 454 and discharge The appropriate positioning of port 442, to form the first hole 443.When drawer component 416 is at least in part from housing 412 (referring to figure When 14A) removing, the opening 493 of sleeve retainer 475 is preferably positioned as the protuberance 492 of housing 412 below and from housing 412 protuberance 492 is laterally outside.When drawer component 416 is properly inserted into housing 412 and funnel 472 and shell During the interior contact of body 412, at least lower pointed end of protuberance 492 is preferably vertically aligned with opening 493.When funnel 472 When being moved upward via four joint element for bar 490 with sleeve retainer 475, protuberance 492 is preferably further inserted into opening In 493.When drawer is removed from housing 412 at the end of operation cycle of the drawer component 416 in pattern of pressure, due to four Joint element for bar 490 makes funnel 472 be down moved in drawer 468 with sleeve retainer 475 with gravity, and opening 493 is downward Ground is moved into being disengaged with protuberance 492.

Referring now to Figure 15 A and Figure 15 B, after operation (pressurization) cycle completes, the pivot action of ejection fork 470 is assisted User removes the container 454 being finished.When drawer component 416 is properly inserted into housing 412 (in pattern of pressure Operation cycle before or after), ejection fork 470 preferably in horizontal level (referring to Figure 15 A).When in pattern of pressure Operation cycle complete when, preferably by first will ejection fork 470 from pivoted to upward position (referring to Figure 15 B) and Container 454 is removed from drawer component 416.Ejection fork 470 is preferably attached pivotally to by least one pin 470b Sleeve retainer 475.Preferably by press ejection fork 470 thumb lug 471 make ejection fork 470 from pivoted to Vertical position.When ejection fork 470 is located in upward position (Figure 15 B), container 454 is at least slightly increased to sleeve retainer 475 tops, thereby assist in from drawer component 416 and remove container 454.

Sleeve retainer 475 includes the cutting assembly 473 with blade 474.Cutting assembly 473 is first or radially-inwardly Sleeve retainer 475 is attached pivotally between position.Operation and insert door 373 phase of the cutting assembly 473 with blade 474 Together.In the embodiment described by Figure 14 A- Figure 14 F, user optionally can remove sleeve from funnel 472 and keep Part 475.Filter basket (not shown) can be convertibly arranged in funnel 472.Filter basket can include integrated sieve or filter Or it can support disposable filter.Insoluble material in bulk or soft Nang Bao can be loaded into filter basket by user.In electric appliance In 410 non-pressurised operation, fluid can leave the second holder via discharge port 442.Then fluid can be with difficulty in bulk Molten material or powder interaction, and by filter basket to funnel 472.In pattern of pressure (i.e. so that container limitation passes through row Put the flow of port 442) or non-pressurised pattern in (that is, brew insoluble material in bulk, soft Nang Bao etc.), fluid is correspondingly from sleeve Keeper 475 or filter basket enter funnel 472.Funnel 472 can include the runway bottom side to hopper outlet 477.The drink brewed Material is discharged into user's container from hopper outlet 477.

The method for optimizing of operation kitchen appliance 410 includes：The 4th holder 480 is removed from housing 412；With water or another kind Liquid fills the 4th holder 460；And the 4th holder 460 is re-attached to housing 412.User is in step defined above Before any one rapid, during or remove drawer component 416 from housing 412 later.For the operation week using container 454 For phase (i.e. pattern of pressure), container 454 is arranged in sleeve retainer 475 by user, until the lid 454b of container 454 It is generally concordant with the upper end 472b and ejection fork 470 of sleeve retainer 475.Simultaneously, when container 454 is down moved to When in sleeve retainer 472, the second hole 445 is formed in container 454 by blade 474.For the operation without using container 454 For cycle (that is, non-pressurised pattern), when brewing loose coffee powder, soft Nang Bao etc., user removes from funnel 472 to be covered Cartridge retainer 475 and filter basket (not shown) is inserted into funnel 472.Then food is inserted into filter basket to prepare Beverage.As shown in Figure 15 A and Figure 15 B, the lock tabs 495 on the opposite side of sleeve retainer 475 allow sleeve to keep Part 475 is easily fixed to funnel 472 and is removed from funnel shifter.

Drawer component 416 is arranged in housing 412 by user, until handle 418 outer surface and housing 412 it is outer Surface is generally concordant (referring to Figure 10).In the 4th embodiment, handle 418 regularly or is immovably attached to pull Part 468.As described above, funnel 472 is moved in appropriate location by four joint element for bar 490.Housing 412 is arranged or be positioned to vessel Recess 414 in, to collect or receive the beverage of preparation.User such as selects vessel sizes by display 488, then presses On/off button 486 is pressed to start the operation cycle.Alternatively, user can only press on/off button 486 to be formed and operated The same amount of beverage for the last time that cycle starts.

Once in the start-up operation cycle, in one embodiment, PCB references, sense or additionally sensed with optional liquid level Device communicates, and the operation cycle is completed to ensure the 4th holder 480 including enough liquid.If amount of liquid is insufficient, display Device 488 will indicate that liquid should be added to the 4th holder 480 by user.This instruction can be with one or more scintigrams Mark the form of (not shown).If there is the enough liquid for being used for completing the operation cycle in the 4th holder 480, then PCB will make pump 484 be powered so that liquid is moved through pump 484 from the 4th holder 480, reaches filling pipe 494 and to the 3rd In holder 460.

Gravity makes liquid be moved through main check valve 462 from the 3rd holder 60 and enters the T of the first holder 426 In connector.Due to gravity, liquid will flow freely through inlet non-return valve 458 from the first holder 426 and enter HWG432 In.Liquid will continue to move in HWG432 and by HWG432 via gravity, and enter in tedge 456.Liquid Outlet non-return valve 464 will be passed through and continued up in tedge 456, until liquid and the liquid in the 3rd holder 460 Body reaches balanced.For example, it can be realized when the liquid level that the liquid level in the 3rd holder 460 is essentially equal in tedge 456 It is balanced.Outlet non-return valve 464 prevents the final phase transformation by gas (for example, steam) to liquid (for example, water) in HWG432 Liquid is drawn onto in HWG432 by the vacuum of generation from tedge 456 to pumpback.

Since after pumping 484 by the relatively short duration being powered first, HWG432 is by by from PCB's Relay power.Liquid in HWG432 and then heating system and produce the bubble of saturation.Bubble is added in HWG432 The pressure of liquid, and for moving the heating liquid in HWG432.Since inlet non-return valve 458 prevents liquid to be moved to Outside HWG432 and back to first or the 3rd in holder 426,460, therefore the liquid heated is pushed to outside HWG432 Portion, into riser 456, and enters in the second holder 440.

In pattern of pressure (that is, discharge port 442 is limited by container/food), the pressure increase in system.Second storage Liquid is forced through discharge check valve 466, discharge port 442 and container 454 by the pressure in device 440 from the second holder 440 And enter vessel to be drunk by user.At least a portion pressure will pass through fluid path 450 (opening or conduit) and Enter in the first holder 426, this is used to make the pressure between the arrival end 434 of HWG432 and the port of export 436 balanced.Hereafter Soon, the gas in HWG432 will start to condense and formed vacuum.Vacuum in HWG432 is combined in the first holder 426 Increased pressure, will be used to make more fluids be drawn into HWG432 by inlet non-return valve 458.Outlet non-return valve 464 is anti- The liquid only previously heated enters back into HWG432 from tedge 456.

After fluid leaves HWG432, since gas is no longer influenced by the relatively high heating of HWG432, in fluid Gas can start to condense.This condensation can form vacuum in 456 and/or second holder 440 of tedge.Discharge non-return Valve 466 prevents food in drawer component 416 and/or gas to be sucked into the second holder 440.Vacuum will pass through conduit 450 and enter in the first holder 426.Vacuum in first holder 426 will be such that liquid is aspirated from the 3rd holder 460 By main check valve 462 and enter in the first holder 426.Liquid is moved to the first holder from the 3rd holder 460 It will be used for equilibrium in 426, vacuum is reduced or eliminated.

System will be repeated or additionally continued the above-mentioned pressure/vacuum cycle, until the 3rd holder 460 and the first storage Whole liquid in device 426 are all consumed (that is, through discharge port).It is pushed in completely or generally whole fluids After the outside of HWG432, the temperature of HWG432 will increase, until thermostat or other mechanism (not shown) opening or additionally Make the energy cessation of HWG432.For example, the sensor (not shown) on thermostat can send signal to PCB, to open Relay on PCB and make current practice cycle arrest.Then drawer component 416 can slide into the outside of housing 412/ Or removed from housing 412, made with handling the container 454 being finished and/or cleaning drawer 468 for the operation cycle below Prepare.

Those of skill in the art will be understood that the food in container 454 and the feelings in no container 454 The uniformity or density of the food prepared under condition are normally inconsistent.The appearance of some types or commercially available trade mark Device 454 significantly provides more resistances or restriction when being discharged from electric appliance.May not be system in the situation of high-drag In the fluids of all heating can be pumped through container 454 in any given pressure cycle.If this occurs, liquid can It can save in the second holder 440 and finally fill up the second holder 440.

When the second holder 440 is filled with liquid, liquid can flow through fluid path 450 and with it is optional Stopper 452 contacts.Since liquid is more sticky than gas, stopper 452 provides increasing to the liquid by fluid path 450 The resistance added.Thus, the pressure in the second holder 440 will keep higher (relative to the first storage in longer duration Device and ambient environmental conditions), this forms larger downward force so that the liquid more heated is pushed into appearance on the fluid of heating In device 454.The fluid of any amount of fluid path 450, which can be passed through, will be flowed into the first holder 426, this may increase into Enter the temperature of the liquid of HWG432.Higher Inlet fluid temperature will cause HWG432 to pump more quickly, and produce more substantially Long-pending gas, this forms larger downward force with general by the pressure increased in the second holder 440 and on the fluid of heating The liquid-driving more heated is into container 454.When the second holder 440 partly or is almost entirely filled with liquid, The vacuum phase in operation cycle will be such that any fluid in fluid path 450 is withdrawn into the second holder 440.It is positioned at conduit Gas on 450 426 side of the first holder may move through the optional stopper 452 in fluid path 450, even in logical During the food crossed in container 454 forms elevated pressures, this also allows vacuum cycle to exist.

Figure 22 shows the another embodiment of kitchen appliance 610.The reference numeral of present embodiment passes through coefficient six Hundred (600) and the reference numeral of prior embodiments can be distinguished, but unless additionally illustrate, otherwise instruction such as institute above The similar elements of finger.The kitchen appliance 610 of present embodiment is substantially similar to prior embodiments.Although can be in fig. 22 Some identical reference numerals are shown, but for brief and convenient purpose, can be omitted some between embodiment here The description of common ground, and therefore the description does not limit.

The distinguishing characteristics of present embodiment is to include being positioned at wall (such as roof) place of the second holder 640, the second storage In the wall (such as roof) of storage 640 or the second holder 640 the gas that separates of the neighbouring one or more of wall (such as roof) (such as air) hole or pressure-regulating valve 647.Stomata 647 and discharge port 642, the entrance of 650 and second holder 640 of conduit Part 640a is separated.Stomata 647 can be floating type, spring-loaded, gravity type, umbrella-type etc..Stomata 647 is for allowing extremely The open position (referring to Figure 22) that some few gases flow through with for fully substantially prevented from or suppress gas flowing It is moveable between the closing position passed through.Stomata 647 is preferably that bias is opened to allow at least one (for example, down) Gas is divided to flow through.For example, stomata 647 can by gravity (that is, due to formed stomata 647 component a part not Rule distribution of weight) or vacuum and bias opening.Under pressure of the stomata 647 preferably in the second holder 640 or pass through By closing (for example, moving upward) by the gas flow rate of valve.

The wall of skirt section 639 from the second holder 640, which upcountry extends, is approximately equal to or is at least slightly distal to stomata 647.Skirt section 639 can be positioned in the roof of the second holder 640 and be extended downwardly from it, or skirt section 639 is at least A part can be positioned in the degree side wall of the angulation of the second holder 640 and angularly upcountry extend to the second storage In device 640.At least a portion in skirt section 639 can extend upward from the roof of the second holder 640 be approximately equal to or to It is few to be slightly distal to stomata 647.Skirt section 639 is preferably about the stomata 647 at least below the roof of the second holder 640 Whole peripheries.The lateral wall in skirt section 639 can extend with madial wall perpendicular to the roof of the second holder 640.Alternatively, skirt section At least one in 639 lateral wall and madial wall can be relative to the roof angulation of the flat of the second holder 640 Degree extension or tapered.The roof extension of at least a portion or whole skirt section 639 with being essentially perpendicular to the second holder 640 The side wall of second holder 640 laterally therein separates.

In operation, stomata 647 preferably stay open or be maintained in the state being at least partially opened (i.e., it is allowed to At least a portion gas passes through it), unless and until the volume of the liquid in the second holder 640 is enough so that the second storage The top surface of liquid in device 640 reaches and/or contacts the lower end in skirt section 639.At this moment, the fluid dynamic in skirt section changes, So that stomata closes.Closure stomata 647 adds the pressure in the second holder 640.Due to the increase in the second holder 640 Pressure, at least a portion liquid is pushed to the outside of discharge port 642 and enters in container 654.Container 654 is additionally As stopper, it hinders or prevents stable current from entering in container 654, the pressure build-up in the second holder 640. Above-mentioned pressure increase is preferably only instantaneous, so that when at least a portion liquid is pushed to the discharge of the second holder 640 After when the outside of port 642 and liquid level reduction soon, stomata 647 reopens.

Due to the above process, such as compared with least some embodiments in the early time, stomata 647 reduces the total of period demand Operating pressure, and help to promote liquid at the more early time point of period demand to the outside of discharge port 642 and enter appearance In device 654.In other words, the closure of the relative brevity of stomata 647 allow kitchen appliance 610 the operation cycle earlier point by liquid Body is promoted and (that is, distributed) into container 654.It has been found that help to close more quickly than no skirt section 639 including skirt section 639 Stomata 647.Preferably, before the liquid level in the second holder 640 is at least slightly reduced, stomata 647 only closes relatively The short period (for example, about 1-2 seconds), thus allows stomata 647 to reopen.Through heating/punching of this kitchen appliance 610 Dwell cycle, repeats the opening and closing of stomata 647.

It is beneficial for several reasons to include stomata 647 in kitchen appliance 610, is included in the early stage leaching of brew cycle Thus the content of saturating container 654, denseer brew or beverage is manufactured to increase the time of contact of coffee and water.Although container During 654 content is impregnated with the long period by using stomata 647, but the entirety of heating/brew cycle of kitchen appliance 610 Length with it is approx or even fully identical in prior embodiments.The closure of stomata 647 also allows 610 shape of kitchen appliance Into smaller and more frequently pressure pulse (for example, work period), this compared with less frequency and larger pressure pulse Wound is smaller on container 654.Thus, reduce cursorily damage container 654, such as undesirably remove or separating foil at the top of At least one of possibility of 654b.Stomata 647 also allows the second holder 640 liquid filling body more quickly, due to allowing Arbitrary gas in second holder 640 leave the second holder 640 with for liquid slot milling, until liquid level rises to skirt section 639 bottom.Further, since the bias of stomata 647 is opened, the second holder 640 of kitchen appliance 610 and other interior magazines Being capable of middle ventilation or " exsiccation " between the operation cycle.

Another distinguishing characteristics of kitchen appliance 610 is located at the pocket type holder 641 in the first holder 626.Bag Formula holder 641 and be positioned at the first holder 626 and the 3rd holder 660 it is at least one in or both between pressure-relief valve 644 are used in combination.As described in earlier embodiments, pressure-relief valve 644 is for allowing the flowing of at least a portion fluid logical The open position crossed and prevent from or at least suppress to move between the closing position (referring to Figure 22) that fluid flows through.Pressure-relief valve 644 be the check-valves biased in closing position.The liquid that the size or pocket type holder 641 of pocket type holder 641 can be kept The volume of body is less than or is even considerably less than the volume of the first holder 626.

Passage or fluid path 637 down extend and into the inside of pocket type holder 641 from pressure-relief valve 644.It is excellent Choosing, the lower end of passage 637 extend downwardly enough distances into the inside of pocket type holder 641, are not contacted with approaching The inner surface of the bottom of pocket type holder 641.Between the inner surface of the bottom of passage 637 and the bottom of pocket type holder 641 At least small or small gap or spacing allow fluid to pass through therebetween.Passage 637 can be and 644 separated list of pressure-relief valve Only component, or passage 637 can be a parts (for example, being integrally formed therewith) for pressure-relief valve 644.

(that is, the first holder 626 is poured into when liquid enters closed-system from the 3rd holder 660 by outlet 661 In) when, pocket type holder 641 preferably receives and/or keeps at least a portion of liquid.Once the liquid in the first holder 626 Whole volumes of body are sufficiently large so that above pocket type holder 641, pocket type holder 641 can receive the top surface of liquid Liquid, this causes at least a portion liquid to be flowed into the inside of pocket type holder 641.Alternatively or in addition, pocket type stores At least a portion of device 641 can sufficiently close to the positioning of outlet 661 so that flow through at least a portion liquid of outlet 661 Reach pocket type holder 641 inside and/or under fall in the inside of pocket type holder 641, although in neighbouring brew cycle knot During beam via outlet 661 " refilling " bags be probably undesirable.In any situation, the upper open end of pocket type holder 641 At least a portion be preferably positioned as positioned at the 3rd holder 660 outlet 661 bottom below height at.In kitchen electricity The operation cycle of device 610 at least initially and the interstage, even if when liquid is discharged from the first holder 626 by HWG632 When, liquid is also maintained in pocket type holder 641.

The operation cycle of kitchen appliance 610 initial and even interstage and the above-mentioned rank for prior embodiments If Duan Ruguo is differed, then and it is similar.However, pocket type holder device 641 changes the operation week of kitchen appliance 610 The late stage of phase.Especially, close to an end or at the end of the operation cycle in the operation cycle, in the first holder 626 Liquid volume is relatively low or there's almost no, and the temperature of HWG632 is relatively high, and check-valves 662 is due to the first storage High pressure in device 626 and close.At this moment, relatively high pressure seeks to balance through closed-system, and thus flowing/movement Point/the region minimum to resistance.

Low-resistance force in closed-system is pressure-relief valve 644.Closed in this way, pressure attempts to escape to by pressure-relief valve 644 Syzygy is united.Pressure promotes the liquid in pocket type holder 641 into passage 637 upward, to promote pressure-relief valve 644 to open.By This, the liquid being previously maintained in pocket type holder 641 is flowed into the 3rd holder 660, and the pressure in closed-system Power grade reduces.It is recently introduced to the liquid in the 3rd holder 660 and flow to outlet 661.Due to the pressure in closed-system Reduce, the pressure difference between the 3rd holder 660 and the first holder causes check-valves 662 to open, and liquid is back to the In one holder 626.At this moment, the liquid of the relatively small amount in the first holder 626 falls or is moved to relatively hot In HWG632.The high temperature of HWG632 makes at least a portion flickering of relatively smaller volume liquid into gas (for example, steam), thus shape Into the compression shock of supplement.This impact promotes at least a portion of gas to leave the second holder 640 simultaneously by discharge port 642 And enter container 654.

Upper surface construction is advantageous in that pocket type holder 641 helps to be formed delay steam and passes through the second holder 240 The release of discharge port 642.After the operation cycle completes, the liquid in container 654 is dried or emptied at least in part to this feature Body so that when container 654 is removed to abandon from kitchen appliance 610, container 654 is seldom formed dirty and messy or do not formed dirty Disorderly.In other words, pocket type holder 641 helps to produce at the end of the operation cycle or at the end of the neighbouring operation cycle relatively small And gentle fluid (for example, steam) pulse or outburst, this helps do not piercing through top seal 654b further or making top Liquid is forced in the case of the body 654a of portion seal 654b from container is separated to the outer of container 654 that is relatively empty or being finished Portion.

Those of skill in the art will be understood that in the case of without departing from its broad inventive concept, can be to upper Embodiment is stated to make a change.It is therefore to be understood that the present disclosure is not limited to disclosed particular implementation, and be intended to It is covered in the interior modification for the spirit and scope of the present disclosure being defined by the following claims.
