(and schematically showing in fig. 2) as shown in Figure 4 A, body 12 further include pressure relief valve 56, this pressure Power relief valve is located at body upper end and is at least in fluid communication via pressure release line 58 with pump 32 and HLG babinets 20a.Pressure Relief valve 56 is biased into one of open position and closed position, is used to discharge HLG by the pressure relief valve in open position Pressure in babinet 20a, and in closed position for the pressure in HLG babinets 20a to be prevented to be released by the pressure relief valve It puts, and pressure relief valve 56 may be actuated by cover piece 16 to another of open position and closed position.

For example, as shown in Fig. 3 A, Fig. 4 A, pivot attachment of the pressure relief valve 56 between cover piece 16 and body 12 Front, i.e. positioned at the one side identical with funnel 62 with liquid storage device 18 of pivot attachment.Pressure relief valve 56 and pressure release line 58 the first aperture 60 is operatively engaged.Valve 56 includes substantially a hollow and dome-type elastic valve body 56a and is generally located at The valve rod 56b at center, valve body limit with integral valve body 56a integral flexible spring, and valve rod project through and with valve body/ Spring 56a is integral.The base portion of dome-shaped elastic valve body 56a is separated with the first aperture 60.First aperture 60 limits pressure release The valve seat of valve 56, this valve seat are sized and shaped in the closed position of pressure relief valve 56 hermetically admission valve stem 56b。

The elastic valve body 56a of valve 56 is by valve rod 56b biass (that is, separating) away from the first aperture 60 so that valve 56 is in and beats Open position is discharged with will pass through the space between the first aperture 60 and the base portion of dome-shaped elastic valve body 56a from the first aperture 60 Pressure in HLG babinets 20a.Therefore, when cover piece 16 (partially or completely opening) in an open position, with valve rod 56b It is disengaged, pressure relief valve 56 is biased into open position by elastic valve body 56a, is separated with the first aperture 60.On the contrary, when lid When part 16 is in its closed position, cover piece 16 mechanically overcomes the bias of elastic valve body 56a, and valve rod 56b is mechanically downward Mobile (such as pressing) is allowed to sealingly engage with the first aperture 60, thus closure valve 56.

As a result, when cover piece 16 is opened, pressure relief valve 56 is opened and pressure cannot be accumulated in HLG babinets 20a (but being discharged from valve 56), and if opening cover piece 16 in the operating process of brew cycle, with regard to relief valve 56, thus beat It opens, and the pressure in HLG babinets 20a substantially releases immediately, and thus prevents from further discharging hot liquid from discharge port 26, As will be described in further detail below.In addition, as described further below, the pressure discharged by valve 56 is re-directed to The usually unapproachable position of consumer is substantially guided not towards consumer, such as, such as non-exclusively, is directed to In body 12, liquid storage device 18 or drip tray.

Optionally, in the embodiment of Fig. 4 B, pivots of the pressure relief valve 56' between cover piece 16 and body 12 is attached Behind connecing, i.e. the opposite side compared with liquid storage device 18 and funnel 62 of pivot attachment.Pressure relief valve 56' is attached to pressure and releases The first aperture 60' of pipeline 58' is put, is in fluid communication with pump 32 and HLG babinets 20a.Pressure relief valve 56' includes generally cylinder The hollow valve body 56a' of shape and from the radially inwardly projecting ring-shaped valve seats 56c' of valve body 56a'.Ring-shaped valve seats 56c' is included substantially The upper perforate 56f' positioned at center.Valve rod 56b' projects through the perforate 56f' of valve body 56a' and valve seat 56c'.Valve rod 56b' It further includes its neighbouring base end and is attached to its lip ring 56d'.Spring 56e'(is such as disc spring) it is operatively coupled on Between valve body 56a' and valve rod 56b', and usually lip ring 56d' is biased into and is sealingly engaged with valve seat 56c'.By This, with pressure relief valve 56 on the contrary, pressure relief valve 56' is biased into closed position by spring 56e'.

Therefore, when cover piece 16 opens (Fig. 4 B), cover piece 16 engages with valve rod 56b' and overcomes the bias of spring 56e' And mechanically actuated (such as pressing) valve rod 56b', lip ring 56d' is thus made to be disengaged and separate with valve seat 56c', And pressure relief valve 56' is opened so that the pressure in HLG babinets 20a to be allowed to be discharged by pressure relief valve.Once cover piece 16 moves Move its closed position, cover piece 16 just mechanically the valve rod 56b' of relief valve 56' so as to being biased back to via spring 56e' Closed position.It is similar with the embodiment of Fig. 4 A as a result, when cover piece 16 is opened, pressure relief valve 56' open and pressure not (but being discharged from valve 56') can be gathered in HLG babinets 20a, and if cover piece 16 is beaten in the operating process of brew cycle It opens, then valve 56' is opened and the pressure in HLG babinets 20a substantially releases immediately, and is thus prevented further from discharge port 26 Hot liquid is discharged, as being discussed in further detail below.

The operation of beverage preparation machine is similar on 2 11st, 2014 entitled " the Computer Controlled submitted The U.S. Patent application No.14/177 of Coffeemaker (computer-controlled coffee machine) ", the operating method described in 347 should Patent application transfers present assignee and is incorporated herein from there through the mode integrally quoted, just as complete herein It illustrates.Nevertheless, the usual operation of beverage preparation machine 10 will now be described.

Beverage preparation machine 10 is powered first, such as beverage preparation machine 10 is inserted into outlet, it is extensive from power failure It is multiple etc..Be powered when, controller 34 at least with the temperature sensor in liquid level sensor (not shown), HLG babinets 20a 36th, heater 22 and air pump 32 communicate.

In order to prepare beverage, user opens cover piece 16 to approach liquid storage device 18 and funnel 62.Once opening cover piece 16, open 54 are closed just to be released and back to open position (Fig. 3 B), controller 34 is made to disconnect electricity with 32 (or making pump 32 and power supply) of pump Connection.Pressure relief valve 56,56' are also opened.Then bulky powder is added in basket 64 or is inserted into box 72 by user In box holder 66, and liquid (such as water) is poured into liquid storage device 18.

In one embodiment, as shown in Fig. 5 A, Fig. 5 B, metering valve 68 is located at the outlet 18b of liquid storage device 18, User to be assisted to determine to pour into the volume of the liquid in liquid storage device 18.Metering valve 68 is in fluid communication with filling pipe 19, and including It limits the valve body 68e of valve seat 68f and projects through valve body 68e and pass upward through the measuring stick of the opening upper end of liquid storage device 18 68a.Measuring stick 68a has gage mark 68b on it, to indicate the volume of the liquid in liquid storage device 18.As in Fig. 5 B most Good to show, metering valve 68 is additionally included in its base end and is nearby attached to its lip ring 68c.Spring 68d (such as disc spring Deng) be operatively coupled between valve body 68e and measuring stick 68a, and usually biases annular sealing element 68c is allowed to and valve seat 68f is sealingly engaged (Fig. 5 A).Therefore, when liquid is poured into liquid storage device 18 (wherein cover piece 16 is opened) by user, metering valve 68 It is biased into closed position (Fig. 5 A) and liquid gathers in liquid storage device 18.User can be according on measuring stick 68a as a result, Gage mark 68b know how much liquid had been poured into.

Topple over once user pours into desired liquid volume, user is just closed cover piece 16.Cover piece 16 overcomes spring 68d's Bias and mechanically actuated (such as pressing) measuring stick 68a (Fig. 5 B), into the open position of metering valve 68, thus in liquid storage device Liquid discharge and enter in HLG babinets 20a by metering valve 68 and filling pipe 19.Pass through the HLG babinets of liquid displacement Air in 20 is escaped by snorkel 38 (including passing through breather port 42) with being biased into the breather valve 40 of its open position Go out.

Optionally, in the embodiment that is shown in figure 6, snorkel 38 is extended near the upper end of liquid storage device 18, and Include observation portion 38a in liquid storage device 18, being from the outer surface of the inside of liquid storage device 18 and/or body 12 for user can See.Observation portion 38a is, for example, transparent or semitransparent, and includes the liquid bulk being used to indicate in HLG babinets 20a thereon Long-pending measurement markers 38b.Floating member 39 is located in snorkel 38, has the floating protruded therefrom towards liquid storage device 18 Bar 39a.Therefore, when user pours into liquid in liquid storage device 18, liquid is flowed into HLG babinets 20a, the liquid in HLG babinets 20a Body raises floating member 39, and the observation portion that the upper end of floating lever 39a passes through snorkel 38 compared with measurement markers 38b 38a is divided to become as it can be seen that thereby indicating that the volume of the liquid in HLG babinets 20a.As in the above-described embodiment, put by liquid The air in HLG babinets 20a changed, escapes also by snorkel 38 and the breather valve 40 for being biased into its open position.

In any embodiment, with rising of the liquid in HLG babinets 20a, liquid reaches and more than snorkel 38 base end.Since HLG babinets 20a is roughly the same with the pressure in snorkel 38, liquid is with the liquid in HLG babinets 20a The rising of body and pass through snorkel 38 into and rising.The liquid level in snorkel 38 is approximately equal in HLG babinets 20a as a result, Liquid level, and effectively it is closed the base end of snorkel 38.Nevertheless, the breather port 42 more than liquid level continues to allow sky Gas, which enters snorkel 38 and passes through breather valve 40, to be escaped.

After the liquid of desired amount is poured into beverage preparation machine 10, cover piece 16 is returned to closed position by user, will Switch it is 54 mechanically actuated to on-position (Fig. 3 C) so that controller 34 is electrically connected with pump 32 (or is connected to electricity by pumping 32 Source).Pressure relief valve 56,56' are also closed.Then user for example brews week by the combination of select button or button to start Phase.Hereafter controller 34 makes heater 22 be powered and in addition via in the feedback acknowledgment HLG babinets 20a from liquid level sensor There are enough liquid.As it should be understood by one skilled in the art that, if controller 34 determines to deposit in HLG babinets 20a In insufficient amount of liquid, then notify user, such as vision or audible alarm are made to user, and disconnect heater 22.

When heater 22 heats the liquid in HLG babinets 20a, temperature sensor 36 communicates with controller 34, provide and The relevant feedback of temperature of liquid in HLG babinets 20a.Controller 34 is all in a manner that those of ordinary skill in the art fully understand It reads to phase property feedback and calculates the temperature in HLG babinets 20a, whether reached with the temperature for assessing the liquid in HLG babinets 20a It arrives or more than default end value, such as in the range of about 89 DEG C to about 95 DEG C.

As should be understood, the expansion that the liquid in HLG babinets 20 causes liquid is heated, this then causes in snorkel 38 Liquid level further rise.In addition, for example steam (the common skill in such as this field is generated via film boiling in HLG babinets 20a Art personnel should be appreciated that), this forms pressure in HLG babinets 20a.Steam attempts to escape HLG babinets via breather port 42 20a.However, due to the diameter of breather port 42, the steam of growth starts to flood (overwhelm) breather port 42, that is, ventilates Aperture 42 starts to limit the flow velocity of enough steam effusions.Once the temperature of the liquid in HLG babinets 20a reaches default end value, Controller 34 just makes air pump 32 be powered.Controller 34 can also close the power supply of heater 22.

The operation of air pump 32 causes the unexpected additional increase of the pressure in HLG babinets 20a, thus floods breather port 42, i.e. breather port 42 is no longer able to adapt to carry out the necessary flow velocity of pressure release by it, and in HLG babinets 20a (larger) pressure builds pressure difference compared between (relatively low) pressure in snorkel 38.Pressure differential causes the liquid in snorkel 38 Further rise, it is final to block breather port 42.Once blocking breather port 42, air is just no longer able to effusion HLG babinets 20a thereby accelerates liquid climbing speed in snorkel 38 and compresses air therein.Air in snorkel 38 it is quick Compression is closed breather valve 40.

As it should be understood by one skilled in the art that, once breather valve 40 is closed, due to the static state in snorkel 38 Air pressure (bernoulli principle), valve 40 remain closed.Once breather valve 40 is closed, the pressure in HLG babinets 20a continues to Increase, the liquid of heating thus forced to be come out from HLG outlets 20c, moved ahead by delivery pipe 28 and by discharge port 26 from It opens, to interact with food powders (such as bulky powder in basket 64 or in box 72).

In the case where using the box 72 of sheathing foodstuff powder, box 72 keeps at least relatively airtight or even complete It is entirely airtight, thus as restriction effect in discharge port 26.To overcome this limitation, heating liquid under pressure flows through discharge Port 26 simultaneously enters in box 72 to be impregnated with food therein.Thus heating liquid is forced under pressure flow through the food being impregnated with simultaneously Box 72 is left to enter in funnel 62.By the way that the heating liquid pressing in box 72, liquid carries out better capillary with powder Effect to form denseer hot beverage, and distributes soaking beverage with faster flow velocity.

On the contrary, in the case where using the wherein basket 81 with bulky powder, basket 64 does not limit usually in an identical manner Discharge port 26 processed.Therefore, as shown in Figure 7, cover piece 16 includes being attached to basket cover piece 70 on the inside of it, and position and into Shape is that the upper end when cover piece is moved to closed position with basket 64 sealingly engages.Sealing engagement between basket cover piece 70 and basket 64 Basket 64 is made to keep at least relatively airtight or even fully airtight similar to box 72 so that the heating fluid of pressurization with The substantially the same mode of box 72 that heating fluid flows through flows through basket 64 and enters funnel 62.Additionally, basket cover piece 70 and basket Sealing engagement between 64 prevents food or liquid to be flowed out from the upper end of basket 64.

Funnel 62 can include the ramped bottom surface to hopper outlet 62a.Soaking beverage is discharged and entered from hopper outlet 62a In the receiving element (not shown) in recess portion 14.Normal brew cycle is had been completed at this time.However, if user is rushing Any moment during dwell cycle opens cover piece 16, then switch 54 is just discharged by cover piece 16 and returns to open position (Fig. 3 B) makes controller 34 be disconnected with pump 32 (or pump 32 and power supply) and is electrically connected, and pressure relief valve 56,56' are also beaten It opens.That is, in the embodiment of Fig. 4 A, cover piece 16 discharges pressure relief valve 56 to return to open position.On the contrary, scheming In the embodiment of 4B, mechanically actuated (such as pressing) the pressure relief valve 56' of cover piece 16 enters open position.In any reality It applies in mode, the pressure in HLG 20a substantially releases immediately.Therefore, because the pressure in HLG babinets 20a be released and Air pump 32 closes power supply (thus without any extra pressure is formed), therefore cannot substantially distribute and heat from discharge port 26 Liquid, so as to prevent the possibility injury to user.

Fig. 8 A- Fig. 9 B show the second preferred embodiment of the beverage preparation machine 110 of the disclosure.Current embodiment Reference numeral can be distinguished by coefficient 100 (100) and the reference numeral of prior embodiments, but unless otherwise specified, it is no Then indicate identical element.However, the component in beverage preparation machine 110 does not change and is scheming with earlier embodiments In the case of not shown in 8A- Fig. 9 B, the reference numeral of earlier embodiments will be used.

As shown in Fig. 8 A- Fig. 9 B, beverage preparation machine 110,110' are included via pressure release line 158 at least with pumping 32 Pressure relief valve 156, the 156' being in fluid communication with HLG babinets 20a.With reference to Fig. 8 A- Fig. 8 B, pressure relief valve 156 includes installation The hollow valve body 156a of generic cylindrical on to the cover piece 116 and complementary valve rod 156b for being installed to body 112.Valve body 156a is attached to the first aperture 160 of pressure release line 158 and including from the radially inwardly projecting annular plate valve of valve body 156a Seat 156c.Ring-shaped valve seats 156c includes the perforate 156f for being substantially located at center.In the open position of cover piece 116, i.e., part or It opens completely, as shown in Figure 8 A, valve body 156a is physically disengaged each other with valve rod 156b.Correspondingly, valve rod 156b with Valve seat 156c is mechanically disengaged, and the pressure in HLG babinets 20a is discharged via perforate 156f, is thus prevented from row It puts port 126 and discharges or further discharge hot liquid.

On the contrary, as shown in figure 8B, in the closed position of cover piece 116, valve rod 156b on body 112 with The valve seat 156c being installed on cover piece 116 is sealingly engaged, and the pressure in HLG babinets 20a is thus prevented to be released by perforate 156f It puts.Therefore, as described in above in the embodiment of beverage preparation machine 10, pressure can be gathered in HLG babinets 20a so as to Hot liquid is discharged via discharge port 126.

It can optionally include the pressure relief valve being installed on cover piece 116 with reference to Fig. 9 A- Fig. 9 B, beverage preparation machine 110' 156'.Similar with valve 156, valve 156' includes valve body 156a', this valve body, which has, is radially therefrom inwardly projecting valve seat 156c' simultaneously And the perforate 156f' including being substantially located at center.Valve rod for example generally elastic valve rod 156b'() via connecting elements 156g' is flexibly attached to valve body 156a'.Valve rod 156b' is separated in its normal unactuated position with valve seat 156c', is thus permitted Perhaps the pressure in HLG babinets 20a is discharged by the space between perforate 156f' and valve rod 156b' from perforate 156f'.Therefore, When cover piece 116 (partially or even wholly opening) in an open position, valve rod 156b' is disengaged with valve seat 156c', and And pressure will not fully be gathered (but to release from valve 156' via discharge port 126' discharging liquids in HLG babinets 20a It puts).

Valve rod 156b' holdings are disengaged with valve seat 156c', unless the closed position in cover piece 116' is mechanically actuated Cheng Yuqi is sealingly engaged.As shown in fig. 9b, in the closed position of cover piece 16, the surface of body 112' engages and mechanically causes Dynamic elasticity valve rod 156b' is allowed to be sealingly engaged with valve seat 156c', thus prevents the pressure in HLG babinets 20a from passing through perforate 156f' discharges.In cover piece 16 from during closed position (Fig. 9 B) is moved to open position (Fig. 9 A), elastic valve rod 156b' It is normally disengaged with valve seat 156c' once no longer being reset upon by body 112' contacts.However, such as ordinary skill What personnel should be appreciated that, valve rod 156b' can pass through any one of a variety of distinct methods as known in the art and valve seat 156c' is separated, and such as, bullets of the valve rod 156b' away from valve seat 156c' can be biased via when not activated by body 112' Spring or optional bias piece.

As shown in Fig. 8 A, Fig. 8 B, beverage preparation machine 110 can also include being located in pressure relief valve 156 and discharge end Deflecting member 174 between mouth 126.In the embodiment as shown, deflecting member 174 is attached to cover piece 116 and extends to In body 112.When cover piece 116 is closed, deflecting member 174 is advanced further in body 112.Additionally, deflecting member 174 It is so structured that it is folding or bending over when cover piece 116 is closed.However, as should be understood, deflecting member 174 can be optionally attached It is connected to body 112 and extends to cover piece 116.Deflecting member 174 is also located at before the aperture 176 in body 112, with drink Expect that the controlled area of draft machine 110 is in fluid communication, i.e., consumer is usually non-accessible or substantially not towards the position of consumer It puts, such as, such as in non-limiting manner, inside, liquid storage device 18 or the drip tray (not shown) of body 112.

In one embodiment, pressure relief valve 156 and aperture 176 can substantially by cover piece 116, body 112 with Deflecting member 174 surrounds.Deflecting member 174 assists to guide the fluid discharged from pressure relief valve 156 towards aperture 176, thus It directs fluid into controlled area.As it should be understood by one skilled in the art that, although not shown in Fig. 9 A- Fig. 9 B Deflecting member 174, but deflecting member 174 can similarly be applied together with pressure relief valve 156'.

Figure 10 A- Figure 10 B show the 3rd preferred embodiment of the beverage preparation machine 210 of the disclosure.Current embodiment Reference numeral can be distinguished by coefficient 200 (200) and the reference numeral of prior embodiments, but unless otherwise specified, Otherwise instruction and identical element indicated above.However, the component in beverage preparation machine 210 does not change simultaneously with prior embodiments And not shown in attached drawing 10A- Figure 10 B in the case of, the reference numeral of prior embodiments will be used.

The beverage preparation machine 210 and the beverage preparation machine of prior embodiments of current embodiment are substantially similar.Although Some identical reference numerals may be shown in Figure 10 A- Figure 10 B, but for brief and convenient purpose, can be saved here The description of some general character slightly between embodiment, and be not therefore limited.Compared with beverage preparation machine 10,110, drink The main distinction of material draft machine 210 is to include pinch valve 280.Although the pressure relief valve not shown in Figure 10 A- Figure 10 B, It should be understood that pinch valve 280 can equally be used with combination pressure relief valve, such as, such as in non-limiting manner, previous Any one of pressure relief valve construction described in embodiment.

As shown, pinch valve 280, which is mounted on, makes the outlet 20c of HLG babinets 20a be fluidly connected with discharge port 226 Flexible discharge tube 228 on.In the embodiment shown in Figure 10 A- Figure 10 B, pinch valve 280 is also fixedly attached to cover piece 216.However, as it should be understood by one skilled in the art that, pinch valve 280 can be optionally attached on body 212 In any part or body 212, pinch valve 280 is allowed to perform function described herein.

In the embodiment as shown, pinch valve 280 includes the supporting member 282 for being fixedly attached to cover piece 216.It is flexible A part for delivery pipe 228 extends through supporting member 282 and by support member support.Pinch valve 280 further includes and support structure The biasing member 284 that part 282 is operably connected.In the embodiment as shown, biasing member 284 is generally in its one end Cantilevered spring fixed to cover piece 216.Spring 284 includes fixture 284a at its opposite end, defines perforate 284b.Perforate 284b surrounds the cross section of flexible discharge tube 228 and the base portion 282a of supporting member 282, thus by the cross section of delivery pipe 228 It is limited between fixture 284a and the base portion 282a of supporting member 282.As it should be understood by one skilled in the art that, can be with Optionally become known any inclined using the currently known of the function of being able to carry out biasing member 284 described herein or later Press component.It similarly, can be optionally using the optional pinch valve for the function of being able to carry out pinch valve 280 described herein.

As shown in FIG. 10A, biasing member 284 (i.e. cantilever spring) is configured to orient/bend in nature clamped position, Wherein downward active force is applied on the cross section of the delivery pipe 228 in perforate 284b by fixture 284a, thus against support The base portion 282a of component 282 clamps the cross section.Therefore, fixture 284a clamps delivery pipe 228, thus substantially blocks delivery pipe 228, and be then essentially prevented fluid and flow to discharge port 226 from HLG outlets 20c.In the embodiment as shown, hang Arm spring can be by the spring steel construction with high yield stress, thus, it is possible to keep clamped position and by away from this position Clamped position (as disclosed below) is returned to after actuating.Biasing member 284 can also by with similar characteristics can selection Material construction.

As shown in Figure 10 B, when cover piece 216 is located at closed position, a part (such as surface) for body 212 is mechanically Engage spring 284 and by spring-actuated into releasing position.That is, when cover piece 216 is moved towards body 212, (the bag of spring 284 Include fixture 284a) it is moved up when being contacted with body 212, overcome the naturally downward active force of fixture 284a.In spring 282 releasing position, the cross section of the delivery pipe 228 in perforate 284b are not substantially clamped or block, thus allow to flow Body flows to discharge port 226 from HLG outlets 20c.Additionally, when cover piece 216 is located at open position or is moved to open position When, spring 284 returns to clamped position, substantially blocks fluid flowing.

As explained above, cover piece 216 movably (i.e. pivotly) is engaged with body 212.Cover piece 216 is closed at it It closes and forms about 0 ° of pivot angle theta in position with body 212, and form in its open position and body 212 at least acute angle Pivot angle theta.Cover piece 216 can limit such as about 110 ° of obtuse angle pivot angle theta in its open position.In an embodiment In, pinch valve 280 is positioned so as to biasing member 284 and sheet during about 15 ° of the pivot angle theta between cover piece 216 and body 212 Body 212 is disengaged.That is, when cover piece 216 pivots about 15 ° away from its closed position (0 ° of pivot angle theta), biasing member 284 Back to clamped position, fluid flowing is substantially blocked.Therefore, once cover piece 216 pivots 15 ° away from closed position, just prevent Fluid stream is stopped and has reached discharge port 226, wherein discharge port 226 is not yet directed toward the direction of user.

As it should be understood by one skilled in the art that, the distance between the pivotal point of cover piece 216 and pinch valve 280 are Determine the factor for the pivot angle theta that biasing member 284 is disengaged with body 212.Pinch valve 280 is more remote apart from pivotal point, bias The pivot angle theta that component 284 is disengaged with body 212 is smaller.Therefore, pinch valve 280 can reposition as needed, so as to The desired pivot angle theta that biasing member 284 is disengaged with body 212 is realized, to return to its clamped position.

Figure 11 A- Figure 13 B show the 4th preferred embodiment of the beverage preparation machine 310 of the disclosure.Current embodiment Reference numeral can be distinguished by coefficient 300 (300) and the reference numeral of prior embodiments, but unless otherwise specified, Otherwise instruction and identical element indicated above.However, the component in beverage preparation machine 310 does not change simultaneously with prior embodiments And not shown in attached drawing 11A- Figure 13 B in the case of, the reference numeral of prior embodiments will be used.

The beverage preparation machine 310 and the beverage preparation machine of prior embodiments of current embodiment are substantially similar.Although It might show some identical reference numerals in Figure 11 A- Figure 13 B, but for brief and convenient purpose, can save here The description of some general character slightly between embodiment, and be therefore non-limiting.With 10,110,210 phase of beverage preparation machine Than the main distinction of beverage preparation machine 310 is to include flow divider 386.

Flow divider 386 includes the entrance 386a being in fluid communication with HLG outlets 20c, be in fluid communication with discharge port 326 the The one outlet 386b and second outlet 386c being in fluid communication with individual bypass port 386d.Containment member 388 (Figure 11 B, Figure 12 B, Figure 13 B) be located in flow divider 386 and can sealingly engage first outlet 386b bypass position (Figure 12 B, 13B) and sealingly engage and move between the exhaust position (Figure 11 B) of second outlet 386c, such as pivotably.

As will be described further below, containment member 388 is mechanically connected to cover piece 316 so that containment member 388 It is oriented in exhaust position in the closed position of cover piece 316, and is oriented in the open position of cover piece 316 in bypass position. At exhaust position (Figure 11 A, Figure 11 B), (second outlet is in fluid communication in shunting valve inlet 386a and flow divider first outlet 386b 386c is sealed by containment member 388).Therefore, in the exhaust position of containment member 388, HLG babinets 20a and discharge port 326 are in fluid communication, and fluid can pass through its discharge as a result,.On the contrary, in bypass position (Figure 12 A- Figure 13 B), flow divider (first outlet 386b is sealed by containment member 388) is in fluid communication in entrance 386a and flow divider second outlet 386c.Therefore, exist The bypass position of containment member 388, HLG babinets 20a and individual bypass port 386d are in fluid communication.Individual bypass port 386d and the bypass position specified are in fluid communication, such as, such as in non-limiting manner, liquid storage device 18, drip tray (not shown) or Optionally specified waste storaging piece (not shown).

In the embodiment as shown, containment member 388 is via eccentric ratio (over-the-center linkage) 390 are mechanically connected to cover piece 316.However, as should be understood, containment member 388 can be via being able to carry out being mechanically connected And with the currently known of rotation of the containment member 388 between its exhaust position and bypass position or later as known A variety of connecting rods, cam, gear etc. are mechanically connected to cover piece 316, such as in the following detailed description of.

With reference to Figure 11 A, Figure 12 A and Figure 13 A, eccentric ratio 390 includes lock bolt claw 390a and the cam being spaced from Component 390b.Each of lock bolt claw 390a, cam member 390b and containment member 388 are attached to extension with being rotatably fixed Pass through their elongate rod 390c.Therefore, any of lock bolt claw 390a, cam member 390b and containment member 388 surround The rotation of the central axis of elongate rod 390c causes other two also to rotate.Eccentric spring 392 is attached to flow divider in its one end 386 and it is attached to cam member 390b in its opposite end.

As it should be understood by one skilled in the art that, eccentric spring 392 is configured at critical point (i.e. central point) The overturning/engage between first position (Figure 11 A) and the second position (Figure 12 A, Figure 13 A).The initial rotation of cam member 390b Eccentric spring 392 is caused to reach its critical point and engages/be turned to another position from a position.Eccentric spring 392 Engaging/overturning causes cam member 390B and thus containment member 388 further rotates.The first position of spring 392 (Figure 11 A) corresponds to the exhaust position (Figure 11 B) of containment member 388, and spring 392 rotates to the second position (Figure 12 A, figure 13A) so that containment member 388 rotates to its bypass position (Figure 12 B, Figure 13 B).

Lock bolt claw 390a includes the groove 390d that can be engaged with the protruding portion 394 protruded from cover piece 316.Protruding portion 394 Cover piece 316 is fixedly attached to, and when cover piece 316 moves between its open position and closed position, lock bolt claw 390a can be rotated compared with protruding portion 394.In the closed position (Figure 11 A) of cover piece 316, protruding portion 394 is contained in lock bolt claw In the groove 390d of 390a.When cover piece 316 is pivoted from closed position towards open position, the groove with lock bolt claw 390a The protruding portion 394 of 390d engagements makes lock bolt claw 390a be rotated around the axis parallel with elongate rod 390c.

Elongate rod 390c is rotated also around its center axis as a result, thus also makes cam member 390b and containment member 388 Rotation.Movement of the cover piece from closed position towards open position also takes off protruding portion 394 and the groove 390d of lock bolt claw 390a From engagement (Figure 13 A).Nevertheless, before lock bolt claw 390a is disengaged with protruding portion 394, cam member 390b's Rotation causes eccentric spring 392 to it up to " critical point " and is turned to its second position from its first position, thus makes sealing structure Part 388 rotates to bypass position from exhaust position.As a result, when cover piece part 316 is moved to its open position, flow divider 386 moves Move its bypass position.As should be understood, cover piece is rotated back to closed position from open position and generates counter motion, so that close Envelope component 388 is rotated back to exhaust position from bypass position.

As explained above, cover piece 316 movably (i.e. pivotly) is engaged with body 312.In an embodiment In, eccentric spring 392 is oriented such that about 15 ° of the pivot that its " critical point " corresponds between cover piece 316 and body 312 Angle.Therefore, when cover piece 316 pivots about 15 ° away from its closed position, containment member 388 rotates to bypass from exhaust position Thus position makes flowing be diverted to bypass port 386d rather than is diverted to discharge port 326.Therefore, once cover piece 216 is remote 15 ° are pivoted from closed position, it is prevented that fluid stream reaches discharge port 326, wherein discharge port 326 is not yet directed toward user's Direction.However, as it should be understood by one skilled in the art that, thus it is possible to vary the machine between containment member 388 and cover piece 316 Tool connects so that in cover piece 316 compared with the different angular position of body 312, containment member 388 is in bypass position and discharge position Switch between putting.

It would be recognized by those skilled in the art that in the case of without departing from the broad sense creative concept of the present invention, it can be right The above embodiment makes a change.For example, beverage preparation machine 10 can include the second liquid storage device, this second liquid storage device is used to receive And/or keep to be used to prepare the liquid of beverage, it is connected with reservoir fluid and preferably selectively from body It removes.It is therefore to be understood that the present disclosure is not limited to disclosed particular implementation, and it is intended to covering by appended power The modification in spirit and scope of the present disclosure that profit requirement limits.
