Description




BACKGROUND OF THE INVENTION




The present invention relates to a selection manifold for a beverage dispenser, such as a post-mix carbonated beverage dispensing system.




A post-mix carbonated beverage dispensing system makes its own carbonated water from a supply of municipal or well water, and then distributes the carbonated water to a plurality of post-mix valves. Each post-mix valve mixes carbonated water with syrup and effects dispensing of a complete beverage. These dispensers are typically found in fast food retailers, theaters, convention centers, sports facilities and the like, and are most often used to fill cups with beverage.




Most all of these plural flavor post-mix dispensers have some type of structure to distribute carbonated water from a single source which may be single or plural carbonator to a plurality of dispensing valves. There typically will be a minimum of four dispensing valves, and it is common to see up to twelve dispensing valves being supplied from a single carbonator.




Recently, consumers have desired the option of purchasing non-carbonated beverages at locations served by post-mix carbonated beverage systems. As a result, manufactures of such beverage dispensing systems have started to provide one or more valves that are connected to a source of chilled but non-carbonated water. These valves then mix a syrup with the non-carbonated water to provide a non-carbonated drink, such as lemonade.




While this additional consumer choice is good for the establishment selling the beverages, it causes problems for the equipment manufacturers and suppliers. Heretofore, the equipment has been built with a fixed number and position of valves that that are supplied with non-carbonated water. The problem is that consumer preferences change, or are unknown at the time equipment has to be purchased and installed. Thus, a beverage dispenser may be installed at a location with only one valve configured to dispense a non-carbonated beverage. However, in actual use, it may be determined that consumers would rather have other types of non-carbonated beverages than the type of carbonated beverage being dispensed. If a user wanted a different selection, so that more valves can dispense non-carbonated beverages, or wants to move the position of the dispenser valves from which non-carbonated beverages are dispensed, the beverage dispensing equipment would have to be modified. While this is difficult and expensive at best, it may be impossible in some systems because the systems are built so that the water (carbonated or non-carbonated) lines are insulated right up to the point where they attach onto the dispensing valves. Therefore, any change would require a complete tearing apart of the equipment.




To add flexibility to beverage dispensers, valve systems have been developed that allow a single dispensing valve to serve either carbonated or non-cabonated beverages. For example, post-mix valves are disclosed in U.S. Pat. No. 5,984,142 to Castaldi and U.S. Pat. No. 5,931,348 to Guadalupi. These systems are switchable, such that either carbonated or non-carbonated water will be delivered by a given dispensing valve. While these post-mix valves provide dispensing valves that can be adjusted at a customer site, neither system enables the valves to be secured in position so as to prevent unintentional switching from one type of water to the other. Further, neither system allows an inspector to easily determine whether a given valve is positioned to deliver carbonated or non-carbonated water.




Thus, there is a need for an improved beverage dispensing equipment that is more versatile, so that an equipment user can more easily change the configuration of the equipment so that different types of beverages can be dispensed as consumer preferences are learned or change.




SUMMARY OF THE INVENTION




A selection manifold has been invented for use with a beverage dispenser that allows the user to easily change the dispenser's configuration. In the preferred embodiment, any dispensing valve on a dispenser can be converted from dispensing a carbonated beverage to a non-carbonated beverage. Additionally, the preferred selection manifold is preferably constructed to enable a selection mechanism to be locked into position to prevent inadvertent switching to a non-selected supply line. Also, the selection manifold is preferably configured to permit ready determination of the status of each selection mechanism in the manifold.




In one aspect, the invention is a selection manifold for use with a beverage dispenser comprising:




a) a manifold block containing at least one cell, each cell having an outlet opening and at least first and second inlet openings; and




b) a selector mechanism associated with each cell, the selector mechanism being actuable between




i) a first position in which fluid entering the cell from the first inlet opening may pass to the outlet opening and fluid from the second inlet is prevented from entering the cell, and




ii) a second position in which fluid entering the cell from the second inlet opening may pass to the outlet opening and fluid from the first inlet opening is prevented from entering the cell.




In a first aspect, the foregoing selector mechanism includes a lock to prevent the unintentional change of the selector mechanism between the first and second positions. In another aspect, the foregoing selector mechanism includes a portion that extends past and an outer edge of the manifold block enabling a viewer to determine the position of the selector mechanism associated with each cell.




In another aspect, a beverage selection manifold comprises:




a) a cell within a manifold body, the cell including an outlet orifice and first and second inlet orifices; and




b) a removable cap including a channel therein positionable adjacent to the cell in a first cap position and a second cap position, wherein the channel allows fluid communication between the outlet orifice and the first inlet orifice in the first position and the outlet orifice and the second inlet orifice in the second position. the selector mechanism comprises a cap with a channel.




In yet another aspect, a selection manifold for use with a beverage dispenser comprises:




a) a manifold block containing at least one cell, each cell having an outlet opening positioned intermediate to first and second inlet openings; and




b) a selector mechanism associated with each cell, wherein the selector mechanism comprises a plunger valve having a seal, the seal of the selector mechanism being transversely actionable with respect to the outlet opening between




i) a first position in which fluid entering the cell from the first inlet opening may pass to the outlet opening and fluid from the second inlet is prevented from entering the cell, and




ii) a second position in which fluid entering the cell from the second inlet opening may pass to the outlet opening and fluid from the first inlet opening is prevented from entering the cell.




In a further aspect, a beverage selection manifold comprises:




a) a manifold block containing an outlet opening positioned intermediate to first and second opposed inlet openings; and




b) a fluid seal having a first seating surface opposite a second seating surface,




wherein the fluid seal is moveable to a first position in which the first seating surface seals the first inlet opening and the second inlet opening remains open, and to a second position in which the second seating surface seals the second inlet opening and the first inlet opening remains open.




In a first method, switching a supply line to a dispensing valve comprises a user selecting the fluid supply to a beverage valve by activating a fluid seal between a first position in which a first side of the fluid seal closes a first fluid supply line, while allowing fluid to flow through a second fluid supply line, and a second position in which a second side of the fluid seal closes the second fluid supply line, while allowing fluid to flow through the first fluid supply line.




In another method of practicing the invention, switching a supply line to a dispensing valve includes a user selecting the fluid supply to a beverage valve by positioning a cap in a first position in which a first side of the cap closes a first fluid supply line, while allowing fluid to flow through a second fluid supply line, and a second position in which a second side of the cap closes a second fluid supply line, while allowing fluid to flow through the first fluid supply line.




The invention and its advantages will best be understood in view of the attached drawings.

DETAILED DESCRIPTION OF THE DRAWINGS AND PREFERRED EMBODIMENTS OF THE INVENTION




Referring now to

FIG. 1

, a beverage and ice dispenser utilizing the present invention is generally indicated by the numeral


1


. The dispenser has a cabinet or box


3


which has side walls


5


, a front wall


7


and a rear wall


9


. A trim ring


11


covers the top of the cabinet and covers an opening in a counter in which the dispenser is installed. A tower


13


extends upward from the top of the cabinet. The tower has plural dispenser valves


15


arranged in a line along the front. The valves have levers


17


which may be moved to open the valves for mixing carbonated or non-carbonated water with flavored syrups to produce the desired soft drinks. Alternatively, the valves may be operated by pushing the front faces


19


of the valves.




A large curved merchandiser advertisement


21


appears at the top of the tower. The merchandiser is backlit and has a translucent front panel


23


on which a message appears.




A drain pan


25


below the valves catches overflows from the cups under the valves and ice which is spilled from overfilled cups. The drain pan


25


is mounted on top of the trim ring


11


. Lifting up on the front


27


of the drain pan and pulling upward on the drain pan removes the drain pan from the top of the cabinet


3


. Lifting or sliding the splash panel


29


upward allows the splash panel to be rocked away from the tower for cleaning. The drain pan


25


has a rectangular opening


31


in its front


27


, through which the ice bin door


33


slides or rotates. After the drain pan has been removed, lifting the front edge of the sliding door upward


33


and tiling the door rearward enables the door to be removed from holders at the sides. In that manner, full access is supplied to the ice storage bin for cleaning the bin and the top of the cold plate, which is integral with the bin. The dispenser may be removed from the counter top by lifting upward on the supporting flanges, which are covered by the trim ring


11


.




In the above mentioned respects, the beverage and ice dispenser of the present invention is like prior art beverage and ice dispensers, such as those disclosed in U.S. Pat. Nos. 5,397,032 and 4,641,763, which are hereby incorporated by reference. The beverage and ice dispenser


1


however includes a unique selection manifold


40


as shown in FIG.


2


.

FIG. 2

also shows a carbonator


42


which is disposed in a chilled zone


44


and a carbonator pump


46


. In the embodiment depicted, a carbonated water line


45


and a non-carbonated water line


47


both feed the selection manifold


40


, chilled water being supplied to system by line


49


. Five water lines


51


,


53


,


55


,


57


and


59


extend between the selection manifold


40


and the dispensing valves


15


on the tower


13


. In the embodiment depicted in

FIG. 2

, there are ten dispensing valves


15


, and thus each of water lines


51


,


53


,


55


,


57


and


59


branches to feed two dispensing valves.




It would of course be possible to increase the size of the selecting manifold


40


and the number of water lines so that each dispensing valve


15


was supplied by its own water line coming from the selection manifold


40


, or fewer lines could be used so that more valves could be paired together.




The carbonator


42


, carbonator pump


46


and dispensing valves


15


can be of any of several known configurations, and are therefore not described in any further detail.




The preferred selection manifold


40


is shown in detail in

FIGS. 3-15

. It is made with a manifold block, which in this embodiment is a valve body


62


. The valve body may be injection molded from a thermoplastic material. The depicted valve body


62


has five cells, each containing a selection mechanism, which in this case is a shuttle valve member


64


. Two specific shuttle valve members


64




a


and


64




b


will be discussed to explain the operation of the selection manifold


40


. In one end (

FIG. 6

) the valve body includes channel plugs


66


. Channels


60


and


66


in the valve body are made by core pins during the injection molding process. The holes through which those core pins are withdrawn must be plugged in some fashion. Besides the plugs


66


, a cap could be secured to cover the end of the valve body.




In the back (

FIG. 8

) the valve body contains two inlets,


67


and


68


, as well as an outlet


63


for each of the five cells within the body. The outlets are connected to water lines


51


,


53


,


55


,


57


and


59


. Inlet


67


is connected to non-carbonated water line


47


and inlet


68


is connected to carbonated water line


45


coming from carbonator


42


(FIG.


2


).




As shown in

FIG. 9

, the shuttle valve members


64


are each fitted with three 0-rings


69


. These 0-rings allow the shuttle valve member


64


to seal off any flow from the cell in which they are housed out the bottom of the valve body. Also, depending on their position, the 0-rings seal between the internal flow channels (


60


and


61


) and the outlets


63


.




For example, when shuttle valve member


64




a


is in the position shown in

FIG. 9

, carbonated water entering the valve body


62


through inlet


68


is allowed to travel through channel


60


and exit through outlet


63




a


. On the other hand, shuttle valve member


64




b


allows non-carbonated water entering the valve body


62


through inlet


67


to travel through channel


61


and exit through outlet


63




b


. Of course, carbonated water in channel


60


cannot exit through any of the outlets


63


except


63




a


. Also, non-carbonated water in channel


61


is prevented from exiting outlet


63




a


by shuttle valve member


64




a


, with the 0-rings sealing inside the valve body


62


.




To prevent the shuttle valve member


64


from being accidentally moved out of its desired position, either by an inadvertent force on the handle


71


of the shuttle valve member extending out of the valve body, or by differences in pressure between the two channels


60


and


61


, a locking plate


72


(

FIG. 9

) is preferably provided. The locking plate


72


cooperates with locking grooves


73


and


74


and a retaining boss


75


formed on the shuttle valve member


64


and best seen in

FIGS. 10 and 11

. Locking groove


73


is used to lock the shuttle valve member in an “in” position, and locking groove


74


is used to lock the shuttle valve member


64


in an “out” position. The reduced diameter section


77


of the shuttle valve member allows for fluid to flow within the cell in which shuttle valve member


64


is placed, as shown in

FIGS. 12 and 13

. 0-rings


69




a


provide a lower sliding seal and 0-ring


69




b


provides an upper sliding seal.

FIG. 12

shows the shuttle valve member set for non-carbonated water. The carbonated water inlet


78




a


into the cell is blocked by the upper sliding seal and 0-rings


69




b


. However, non-carbonated water can enter through inlet


79




b


and flow out the outlet


63




b


.

FIG. 13

shows the valve set for carbonated water, which enters through inlet


78




a


and exits through outlet


63




a


. However, inlet


79




a


is blocked by 0-rings


69




b


. In both cases 0-rings


69




a


prevent water from leaking out the bottom of the valve body


62


.





FIGS. 14A and 15A

show the internal aspects of the valve body


62


and how the shuttle valve locking plate


72


is used.

FIGS. 14B and 15B

show just the locking plate


72


and the shuttle valve member


64


. The locking plate


72


includes a boss or opening that allows the shuttle valve member to be retracted or extended when the valve is in one position, (

FIGS. 15A and B

) but when the shuttle valve member is rotated about its axis, such as by 180°, the retention boss


75


interferes with the locking plate, preventing the shuttle valve member from sliding in or out (FIGS.


14


A and B).




As shown in

FIGS. 3

, and


8


-


9


, each handle


71


extends past the outer edge of selection manifold


40


. By providing a section of each shuttle valve


64


that is visible after the selection manifold is mounted to a dispenser, an inspector can easily determine the position of each valve. This feature of the invention is a distinct advantage over prior art systems that require detailed inspection or sampling to determine whether carbonated or non-carbonated water is selected.




A second embodiment of a selection manifold


140


is shown in

FIGS. 16 and 17

. This embodiment uses a direct acting plunger inside the cell within the manifold body


162


. Sealing washers


169


are used to seal against valve seats


166


. In the position shown in

FIG. 16

, non-carbonated water


147


can flow out of outlet


143


. In the position shown in

FIG. 17

, carbonated water


145


can flow out of outlet


143


. In similarity to the foregoing embodiment, the position of stem


164


, and hence, the position of the valve, can be easily determined by simply viewing selection mainifold


140


.




Those skilled in the art will appreciate that the selector mechanisms described above utilize a sealed valve system. Accordingly, when switching from one supply line to another, there is no need to relieve the pressure in the supply lines prior to changing the valve position. By eliminating the need to depressurize supply lines, numerous time-consuming procedures, such as turning power supplies off and on and bleeding supply lines can be avoided. Further, spillage of water, which can damage counter tops and cabinets is also avoided.




A third embodiment of a selection manifold


210


is shown if

FIGS. 18-22

. In this embodiment the selection mechanism is a selector cap


212


that is held onto the manifold body


214


by retention screws


216


. The body


214


has two inlets


222


and


223


and an outlet


224


for each cell in the body. Holes


232


in the face of the body connect with a flow channel extending inwardly from inlet


222


. Holes


233


also in the face of the body connect with a flow channel extending inwardly from inlet


223


. Each cell also has another hole


234


in the face of the body, connecting with the outlet


224


for the cell.




The selector cap


212


has an elongated channel


225


in one face. This channel does not open to any other face of the cap. The channel


225


extends from the center of the face off to one side by a distance equal to the distance between holes


232


and


234


(or holes


233


and


234


) in the face of the manifold body


214


.

FIGS. 21 and 22

show the cap


212


attached to the face of the body


214


. In one position,

FIG. 21

, non-carbonated water from inlet


222


is able to pass through the cell to the outlet


224


, while carbonated water from inlet


223


is blocked. In the position shown in

FIG. 22

, carbonated water is allowed to pass through the cell in the selection manifold. As readily seen in

FIGS. 18-22

, cap


212


is repositioned on manifold body


214


by flipping the cap over and reattaching retention screws


216


.




A fourth embodiment of the selection manifold


310


of the present invention is shown in

FIGS. 23 and 24

. The manifold has a body


312


and a selector mechanism which comprises a rotating stop cock or ball valve


314


. Depending on the position of the ball valve


314


, carbonated water from inlet


323


(

FIG. 23

) on non-carbonated water from inlet


322


(

FIG. 24

) is permitted to flow through internal channel


318


to outlet


324


.




A fifth embodiment of a selection manifold


410


is shown in

FIGS. 25-26

. In this embodiment the selection manifold is built into a mounting block


412


used to mount a post-mix beverage dispensing valve


414


onto a beverage dispenser. A two-way syrup valve


416


and a three-way water valve


418


fit in the mounting block


412


. Carbonated water enters the block


412


through port


420


. Non-carbonated water enters the block through port


422


. Syrup enters the block through port


424


. The stem of each of valves


416


and


418


have a channel through their center, open at the bottom, that communicates respectively with syrup outlet port


426


and water outlet port


428


on block


412


, which connect onto fittings


430


and


432


on the back of mixing valve


414


. The syrup valve


416


has only one inlet


434


, scaled with an O-ring (not shown). The water valve


418


has two inlets


436


and


438


when the valve


418


is inserted into mounting block


412


in the position shown in

FIGS. 25 and 26

, inlet


436


mates with port


422


so that non-carbonated water flows through the selection manifold


410


. If the valve


418


is rotated 180°, inlet


438


mates with port


420


, and carbonated water flows through selection manifold


410


.




A sixth embodiment of a selection manifold


510


is shown in

FIGS. 27-28

. This selection manifold consists of four sets of water and syrup valves in one block


512


. Each set is configured like the valves


416


and of FIG.


25


. The entire manifold


510


also acts as a mounting block to mount multiple post-mix beverage dispensing valves


514


to a beverage dispensing machine. Individual valve blocks


513


, with simple two-way valves


517


and


519


, are mounted on the back of each post-mix dispensing valve


514


. These valve blocks


513


allow water and syrup flow to be shut off to the valves


514


. The selection manifold has one inlet port


520


for carbonated water and one inlet port


522


for non-carbonated water. Channels


523


and


525


extend from these inlet ports through the length of the block


512


, supplying carbonated water and non-carbonated water to the individual water valves


518


. Syrup inlets


524


allow syrup to flow into channels in the block


512


and out through syrup outlets


526


. There is one set of syrup inlets and outlets for each block


513


and valve


514


.




A seventh embodiment of a selection manifold


610


is shown in

FIG. 30

, and used in the beverage dispensing system shown in FIG.


29


. Carbonated water flows through channels


625


in block


612


, while non-carbonated water flows through channels


623


. Selector valves


618


can be rotated 180° so that water from one of the channels


623


and


625


flows through the inlet


636


in the selector valve and out the back of block


612


, where it connects to lines going through cold plate


650


in the beverage dispensing system


600


. Cold water from water cooler


604


supplies a water to a carbonator


606


, and optionally an ice makes


608


.




The present invention can be used with other types of beverage dispensing systems than the beverage and ice dispenser


1


. Counter-electric and remote carbonation systems can also use the selection manifold of the present invention. In addition to switching between carbonated and non-carbonated water, the system could be designed to switch between two or more beverages such as sodas, beers and wines.
