BACKGROUND
[001] Beverage dispensers for soft drinks, sports drinks, waters, and the like,
generally include a device for producing carbonated water. A common device for
producing and storing carbonated water is a carbonator. Generally described, most
carbonators include a pressurized tank, a plain water inlet, a carbon dioxide gas inlet,
and a carbonated water outlet. Once the plain water and the carbon dioxide gas mix
within the tank, the carbonated water generally remains in the tank until needed for a
beverage. The carbonator may be chilled or the carbonated water may be chilled at
another location prior to a dispense. Most commercially available beverage dispensers
are generally designed for large volume commercial outlets such as restaurants and
other types of retail outlets. The beverage dispensers thus must accommodate large
volumes of beverages within a small amount of time. Given such, beverage dispenser
design has focused generally on maximizing cooling and dispensing speeds. Such
beverage dispensers thus may be relatively large, expensive, and generally not intended
to be portable. There is thus a desire for a lower volume beverage dispenser for
carbonated beverages. Such a beverage dispenser, however, should provide the same
quality carbonated beverages as produced by conventional beverage dispensers while
being reasonable in terms of size, cost, variety, and ease of operation in terms of
dispensing, refilling, maintenance, and the like. Commercially available beverage
dispensers for soft drinks, sports drinks, waters, and the like, generally include a device
for producing carbonated water. A common device for producing and storing
carbonated water is a carbonator. Typically, carbonators include a pressurized tank, a
plain water inlet, a carbon dioxide inlet, and a carbonated water outlet. Once the plain
water and the carbon dioxide gas mix within the tank, the carbonated water generally
remains in the tank until needed for a beverage. The carbonator may receive chilled
plain water or the carbonator water may be chilled at another location prior to a
dispenser. Typically, commercially available beverage dispensers are designed for
large volume commercial outlets, such as restaurants, fast food chains, and other types
of food and beverage stores. As a result, the beverage dispensers must accommodate
large volumes of beverages within a limited amount of time. Therefore, typical
beverage dispenser designs have focused on maximizing cooling and dispensing needs.
Such beverage dispensers have been relatively large, expensive, and generally not
intended to be portable.
SUMMARY
[002] This summary is provided to introduce a selection of concepts in a
simplified form that are further described below in the Detailed Description. This
summary is not intended to identify key features or essential features of the claimed
subject matter, nor is it intended as an aid in determining the scope of the claimed subject
matter.
[003] The present application and the resultant patent thus provide a beverage
dispenser for mixing a flow of concentrate, a flow of water, and a flow of gas. The
beverage dispenser may include a carbonator with a water input in communication with
the flow of water, a gas input in communication with the flow of gas, a carbonated
water
output, and a chilling reservoir in communication with the flow of water, and a
dispensing nozzle in communication with the flow of concentrate and a flow of
carbonated water from the carbonated water output of the carbonator. Selecting and
dispensing multiple brand beverages at a dispenser apparatus from a dispenser may be
provided. A first and second user input indicating a beverage and flavor respectively
may be received at a user interface. Where an individual beverage concentrate or
flavor has been exhausted a control device may switch to a remaining beverage
concentrate or flavor. Furthermore, the control device can output a signal to a user via
the user interface. The user interface may indicate a no or low flow condition by
highlighting a specific icon associated with the beverage concentrate or flavor,
providing a small indication over the specific icon, or other visual indicators in
association with a sold-out condition on the user interface. Where the specific
beverage concentrate or flavor has been replenished, a sensor may detect a replenished
beverage concentrate or flavor. Subsequently, the control device may remove the
signal sent to a user via the user interface. The present application and the resultant
patent further provide a method of operating a beverage dispenser. The method may
include the steps of filling a water/ice reservoir with water and ice, circulating a first
flow of water about a carbonator to chill the carbonator, flowing a second flow of water
into the carbonator, flowing a flow of gas into the carbonator to produce a flow of
carbonated water, flowing the flow of carbonated water to a dispensing nozzle, and
flowing a flow of concentrate through a concentrate coil in the carbonator and to the
dispensing nozzle. The present application and the resultant patent further provide
carbonator for use with a beverage dispenser for mixing a flow of concentrate, a flow
of water, and a flow of gas. The carbonator may include a water input in
communication with the flow of water, a gas input in communication with the flow of
gas, a carbonated water output, a chilling reservoir in communication with the flow of
water, and a concentrate coil in communication with the flow of concentrate.
[004] The present application and the resultant patent further provides for a
potable water/ice slurry refrigeration system. The potable water/ice slurry refrigeration
system may include a water/ice slurry tank, a heat exchanger positioned about the
water/ice slurry tank, an ice bin positioned about the water/ice slurry tank, and a grate
positioned between the water/ice slurry tank and the ice bin. The present application
and the resultant patent further provide a method of chilling a number of fluids in a
beverage dispenser. The method may include the steps of positioning an amount of ice
in an ice bin, allowing the ice to melt into a water/ice slurry tank, flowing water into
the water/ice slurry tank, flowing an ingredient through a heat exchanger positioned
about the water/ice slurry tank, flowing water from the water/ice slurry tank to a
nozzle, and flowing the ingredient from the heat exchanger to the nozzle to create a
beverage.
These and other features and advantages will be apparent from a reading of the
following detailed description and a review of the associated drawings. It is to be
understood that both the foregoing general description and the following detailed
description are illustrative only and are not restrictive of the invention as claimed.

[029] The beverage dispenser 100 also may include a carbonator 600. The
carbonator 600 may be positioned within the housing 110. The carbonator 600 may
have any size, shape, or configuration. An example of the carbonator as is described
herein is shown in Figs. 1-4.
[030] The carbonator 600 may include an outer jacket 610. The outer jacket
610
may be partially cylindrical in shape and may have any length or diameter. The outer
jacket 610 may be made from an outer layer of an acrylic or similar types of materials
and an inner layer of an insulating material with good thermal characteristics. Other
types of materials may be used herein.
[03 1] The carbonator 600 may include a water jacket 620. The water jacket
620
may be positioned within the outer jacket 610 and may define a chilling reservoir 630
therebetween. The water jacket 620 may have any length or diameter. The water jacket
620 may be made out of metals and other types of materials with good thermal
characteristics. Likewise, the chilling reservoir 630 may have any length, diameter, or
volume. The water jacket 620 may be a pressurized tank for mixing the water 520 and
the carbon dioxide 485 therein. The chilling reservoir 630 may surround the water
jacket
620. A water input port 640 and a water output port 650 may extend through the outer
jacket 610 to the chilling reservoir 630. The chilling reservoir 630 may be in
communication with the water/ice reservoir 510 via a recirculation loop 660. The
recirculation loop 660 extends from the water/ice reservoir 510 to the water input port
640 via the recirculation pump 570 and then back to the water/ice reservoir 510 via the
water output port 650. The recirculation loop 660 thus keeps the water 520 in the
chilling reservoir 630 cold so as to chill the water jacket 620 and the internal
components thereof. Other components and other configurations may be used herein.
The carbonator 600 may include a heat sink 670 positioned about the water jacket 620.
In this example, the heat sink 670 may be a finned heat exchanger 680. Other types of
heat exchangers may be used herein. The heat sink 670 may have any size, shape, or
configuration. Positioned between the water jacket 620 and the heat sink 670 may be a
thermo-electric chilling device 690. The thermo-electric chilling device 690 may be a
Peltier device 700 and the like. As is known, a Peltier device creates a heat flux at a
junction between two different types of materials via an electric charge. The Peltier
device has the advantages of being efficient and largely silent. The Peltier device 700
thus transfers heat from the water jacket 620 to the heat sink 670 so as to cool the water
jacket 620 and the internal components thereof. Other types of cooling devices also
may be used herein. A fan 710 or other type of air movement device may be positioned
about the heat sink 670. Other components and other configurations may be used
herein.
[032] The outer jacket 610 and the water jacket 620 of the carbonator 600 may
be enclosed by a two-piece cap 720. The two-piece cap 720 may include a lower cap
730. The lower cap 730 may have any size, shape, or configuration. The lower cap 730
may have a number of mounting flanges 740 extending therefrom. The lower cap 730
may be made from any type of substantially rigid thermoplastic materials and the like.

have a number of solenoid mounts 760 and passageways 770 formed therein. The upper
cap 750 may have any size, shape, or configuration. The upper cap 750 also may be
made from any type of substantially rigid thermoplastic material and the like.
[033] The carbonator 600 may include a number of concentrate coils
positioned
within the water jacket 620 to chill the beverage concentrate therein. The concentrate
coils may have any size, shape, or configuration. A first concentrate coil 760 may be in
communication with the first beverage cartridge 330 to chill the first beverage
concentrate 340, a second concentrate coil 790 may be in communication with the
second concentrate cartridge 356 to chill the second beverage concentrate 360, a third
concentrate coil 800 may be in communication with the third concentrate cartridge 370
to chill the third beverage concentrate 380, and a fourth concentrate coil 810 may be in
communication with the fourth concentrate cartridge 390 to chill the fourth beverage
concentrate 400. Any number of concentrate coils may be used herein. The concentrate
coils may extend through the two-piece cap 720 or elsewhere in the carbonator 600 via
a number of concentrate ports 820 extending through. The beverage concentrates 340,
360, 380,400 thus may be pumped via the concentrate pumps 410 into the carbonator
600 so as to be chilled within the concentrate coils 780, 790, 800, 810, and then onto
the dispensing nozzle 580. Other components and other configurations also may be
used herein.
[034] The carbonator 600 may be in communication with the flow of carbon
dioxide 485 from the carbon dioxide source 470 via a carbon dioxide solenoid 830. The
carbon dioxide solenoid 830 may be of conventional design. Alternatively, any type of
flow control device may be used herein. The carbon dioxide solenoid 830 may be
mounted on the two-piece cap 720. The carbon dioxide solenoid 830 may be in
communication with a stinger tube 840 via a check valve 850. The stinger tube 840
may
extend into the water jacket 620 towards a bottom end thereof and may be positioned
within the concentrate coils 780, 790, 800, 810. A pressure relief valve 860 may be
positioned on the two-piece cap 720 adjacent to the carbon dioxide solenoid 830. The
pressure relief valve 860 may be of conventional design. Other components and other
configurations may be used herein.
[035] The carbonator 600 also may include a water inlet 870. The water inlet
870 may be in communication with the flow water 520 from the water/ice reservoir 510
via the fill pump 560 or otherwise. The water inlet 870 may extend through the two
piece cap 720 into the water jacket 620 via a water check valve 880. The water check
valve 880 may be of conventional design. The water inlet 870 may lead to a water
nozzle 890 so as to add velocity to the flow of water 520 for increase agitation therein.
The water nozzle 890 may have an area of narrowing diameter and the like. Other
components and other configurations may be used herein.
[036] The carbonator 600 also may include an agitation bypass system 900.
The agitation bypass system 900 may include an agitation bypass solenoid 910. The
agitation bypass solenoid 910 may be of conventional design. Alternatively, any type of
flow control device may be used herein. The agitation bypass solenoid 910 may be
positioned about the two-piece cap 720 and may be in communication with a bypass
dip tube 920 extending into the water jacket 620. Water 520 from within the water
jacket 620 may be forwarded into a recirculation loop 930. The recirculation loop 930
extends from the bypass dip tube 920, to the agitation bypass solenoid 910, to the
recirculation pump 570, and back through the water inlet 870. The recirculation loop
930 may serve to provide agitation to the water stream 520 so as to increase the level of
carbonation absorption therein. The agitation bypass solenoid 910 also may assist in
self-purging the carbonator 600 upon initial use. A carbon dioxide vent muffler 940
may be positioned about the recirculation loop 930. The carbon dioxide vent muffler
940 may be of conventional design. Other components and other configurations may be
used herein.
[037] The carbonator 600 also may include a carbonated water outlet system
950. The carbonated water outlet system 950 may include a carbonated water solenoid
960. The carbonated water solenoid 960 may be of conventional design. Alternatively,
any type of flow control device may be used herein. The carbonated water solenoid 960
may be positioned about the two-piece cap 720. The carbonated water solenoid 960
may be in communication with a flow of carbonated water 970 from within the water
jacket 620 via a water dip tube 980. The water dip tube 980 extends into the water
jacket 620 near a bottom end thereof. An output check valve 990 may be used. The
output check valve 990 may be of conventional design. The carbonated water output
system 950 may be in communication with the dispensing nozzle 580 via a carbonated
water line 1000. Other components and other configurations may be used herein.
[038] The carbonator 600 also may include a temperature sensor 1010, a level
sensor 1020, and other types of sensors. A flow meter 1030 may be used on the
carbonated water line 1000 and elsewhere. The sensors 1010, 1020 and the flow meter
1030 may be of conventional design. The sensors 1010, 1020 and the flow meter 1030
may be in communication with the controller 1020. Other components and other
configurations may be used herein.
[039] In use, the beverage cartridges 330, 350, 370, 390 and the flavor
cartridges 420, 430, 440, 450 may be positioned within the housing 110. The water/ice
reservoir 510 may be filled with water 520 and/or ice 530 and positioned within the
housing 110. Likewise, the carbon dioxide source 470 may be positioned within the
housing 110. The fill pump 560 may fill the water jacket 620 of the carbonator 600
with water while the recirculation pump 570 starts to circulate water 520 through the
chilling reservoir 630 via the recirculation loop 660. The agitation bypass system 900
may be used so as to increase the carbonation level of the carbonated water 970 within
the water jacket 620. Likewise, the carbonator 600 and the carbonated water 970
therein may be further chilled via the thermoelectric cooler 690.
[040] Once the carbonated water 970 within the water jacket 620 of the
carbonator 600 has reached a predetermined temperature, the beverage dispenser 100
may allow a consumer to select a beverage via the touchscreen 140 of the consumer
input device 130. The consumer may select one of the beverages 160, 180,200,220 via
one of the beverage icons 160, 180, 200, 220 and/or one of the flavors 240, 260, 280,
300 via the flavor icons 230, 250, 270, 290. Once the appropriate beverage is selected,
the consumer may press the pour icon 310 or the pour icon 320. The controller 120 then
may activate the appropriate concentrate pump 410 so as to pump the beverage
appropriate concentrate 340, 360, 380,400 from the appropriate concentrate cartridge
330, 350, 370, 390 into the appropriate concentrate coil 780, 790, 800, 810 so as to
chill the concentrate therein. Likewise, the controller 120 may activate the carbonated
water solenoid of the carbonated water outlet system 950 so as to forward a flow of
carbonated water 970 at the appropriate flow rate. The beverage concentrate and the
carbonated water then may mix within or downstream of the dispensing nozzle 580.
More than one concentrate 340, 360, 380,400 and/or more than one flavor 240, 260,
280, 300 may be used herein to create a single beverage. The fill pump 560 may refill
the water jacket 620 with water 520 from the water/ice reservoir 510 when appropriate
so as to ensure a predetermined volume of carbonated water 970 therein. Other
components and other configurations may be used herein.
[041] The beverage dispenser 100 described herein thus provides quality
carbonated beverages and the like without the use of bulking and noisy refrigeration
systems. Rather, cooling is provided via the water/ice reservoir 510 and the
thermoelectric cooler 690. The consumer merely needs to keep the water/ice reservoir
510 full of an adequate supply of water 520 and/or ice 530. Likewise, the carbonator
600 includes all of the components required to provide carbonated water 970 within a
single integrated module as opposed to the several components usually required. The
use of the carbonator 600 thus provides a significant size reduction as well as
associated cost reductions. The beverage dispenser 100 may be portable and may be
available for use on a conventional countertop, tabletop, and the like. Moreover, the
carbonator 600 may quickly cool down to the appropriate temperature and maintain
that temperature during typical use. The flow of carbonated water 970 also may be used
to sanitize the cartridges, the coils, the lines, and the like.
[042] Fig. 5 through Fig. 11 shows an example of a potable water/ice slurry
refrigeration system 1100 as may be described herein. The potable water/ice slurry
refrigeration system 1100 may include an ice bin 1110 separated from a slurry tank
1120 by a grate 1130. The ice bin 1110 may have two ledges 1140 that the grate 1130
may rest thereon. Other types of support structures may be used herein. The grate 1130
may be manufactured from stainless steel, plastics, or other types of food safe
materials. The grate 1130 may have spacings 1150 that retain ice cubes 1160 over a
specific size. For example, the grate 1130 may have spacings 1150 that will allow 3/8
inch (9.525 millimeter) ice cubes to pass through, but not 112 inch (12.7 millimeter) ice
cubes. In addition, the grate spacings 1150 may be uniform or may vary. For instance,
certain areas of the grate 1130 may allow ice cubes of 3/8 inch in size to pass through,
but not 112 inch in size. Other areas of the grate 1130 may allow ice cubes of 112 inch
in size to pass through, but not 5/8 inch (15.875 millimeters) in size. The varying grate
spacings 1150 may allow for a more heterogeneous mixture in the slurry tank 1120.
[043] The slurry tank 1120 includes a water/ice slurry 1170 therein. The
water/ice slurry 1170 may cool a flow of the macro-ingredients such as a concentrate or
a sweetener or other types of ingredients. Specifically, the macro-ingredients may pass
through a micro-channel heat exchanger 1180. The micro-channel heat exchanger 1180
may be braised to the undersurface of the slurry tank 1120 or may be otherwise
attached or positioned. The micro-channel heat exchangers 1180 may be sized
accordingly to the planned operating capacity of the overall dispenser. For example,
dispensers with an expected high throughput may be larger to allow for greater cooling
capacity. Dispensers with an expected low throughput may have smaller micro-channel
heat exchangers 1180 that may achieve the desired cooling while the ingredients are
resting within the micro-channel heat exchanger 1180 between dispensing. The microchannel
heat exchangers 1180 described herein may be constructed in a variety of
fashions. For example, the micro-channel heat exchanger 1180 may be extruded. The
micro-channel heat exchangers 1180 also may be manufactured via a stacked plate
construction method. Other types of manufacturing techniques may be used herein.
During operation, a flow of water 1190 may enter the slurry tank 1120 via a water inlet
1200. This water 1190 may mix with the ice 1160 passing through the grate 1130 to
form the water/ice slurry 1170. As the chilled water 1190 is need, the water 1190 may
exit the slurry tank 1120 via a water outlet 1210 and head to a carbonator or a
dispensing nozzle. The slurry tank 1120 may include a low level sensor 1220 that
controls the flow of water 1190 into the slurry tank 1120. In addition, the slurry tank
1120 may include an agitator that may be used to break up ice bridges that may form as
the ice melts. A sanitizer 1230, UV or filtration, may be connected to the slurry tank
1120 and allow the water 1190 to be sanitized. Other types of sanitation techniques
may be used herein. An overflow line 1240 also may be used herein. Other components
and other configurations may be used herein.
[044] Fig. 6 and Fig. 7 show a grate 1250 that may be formed of a series of
tubing 1260. The tubing 1260 may allow the grate 1250 to act as a pre-chiller for the
water 1190. For example, instead of the water 1290 flowing directly into the slurry tank
1020, the water 1190 may first flow through the tubing 1260 of the grate 1250 for
chilling. This pre-chilling also may allow heat to flow from the water 1190 to the ice to
break up the ice bridges that may form as the ice melts. Furthermore, instead of the
tubing 1260, the micro-channel heat exchangers 1180 also may be used to form the
grate 1250. Other components and other configurations may be used herein.
[045] The grate 1250 may be connected to the incoming water inlet 1200 via a
quick disconnect fitting 1270. The quick disconnect fitting 1270 may act as a valve to
stop the flow of water 1190 when the grate 1250 is disconnected. Also, an external shut
off valve (not shown) also may be used. As shown in Fig. 7, the grate 1250 may be
removable to allow a user greater access to the slurry tank 1120 for cleaning. In
addition to pre-chilling the incoming water 1190, the grate 1250 also may include
sections that allow for the ingredients to flow therethrough for pre-chilling.
Furthermore, instead of one grate 1250 divided into sections, multiple grates 1250 may
be used. The multiple grates 1250 may be positioned in the same plane or the grates
1250 may be layered. For instance, as shown in Fig. 8, the inlet water 1190 may pass
through a bottom grate 1280 and the ingredients may pass thought an upper grate 1290.
Each of the grates may have differently sized spacings 1150 to allow progressively
smaller sized ice cubes to reach the water/ice slurry 1170. Other components and other
configurations also may be used herein.
[046] Fig. 9 shows the slurry tank 1120 with the micro-channel heat exchanger
1180 positioned within the water/ice slurry 1170. In this example, a pump 1300 used to
sanitize the water 1190 also may act as a recirculation pump that may allow the water
1190 to cool the micro-channel heat exchanger 1180 via forced convection. As above,
the grate(s) may be used as pre-chillers and/or the grates may be removable for easy
cleaning.
[047] Fig. 10 shows the slurry tank 1120 with a first micro-channel heat
exchanger 1310 attached thereto. The ingredients may flow through the first microchannel
heat exchanger 1310 to be cooled prior to delivery to a nozzle. In addition, a
second micro-channel heat exchanger 1320 may be connected to the first micro-channel
heat exchanger 1310. In other words, the first micro-channel heat exchanger 1310 may
be sandwiched between the slurry tank 1020 and the second micro-channel heat
exchanger 1320. Cooled water 1190 may flow through the second micro-channel heat
exchanger 1320 to provide extra cooling capacity to chill the ingredients flowing
therethrough. The second micro-channel heat exchanger 1320 may be arranged in
parallel or in cross flow to the first micro-channel heat exchanger 1310. Other
components and other configurations also may be used herein.
[048] Fig. 11 shows an example of a grate 1330 that may be used as a
prechiller. The grate 1330 may include an inlet 1340 connected to an inlet manifold
1350. The inlet manifold 1350 may disperse the fluid to various tubing 1260 that may
deliver the fluid to an outlet manifold 1360. From the outlet manifold 1360, the fluid
may flow to an outlet 1370. The grate 1330 may have any size, shape, or configuration.
Other components and other configurations also may be used herein.
[049] FIG. 12 is a schematic view of an operating system 1201 for dispensing
multiple flavored brands consistent with embodiments of the disclosure. As shown in
FIG. 1, the components of the operating system 1201 may be positioned within a

flavor cartridges may be used herein. Each of the flavor cartridges may be in
communication with a flavor pump 321 . The flavor pumps 321 may be of conventional
design and may be a positive displacement pump and the like. The positive
displacement pump may be a solenoid pump, a gear pump, an annular pump, a
peristaltic pump, a syringe pump, a piezo pump or any other type of positive
displacement device that is designed to pump a fixed displacement for each pump
cycle.
[051] The operating system 1201 also may include a dispensing nozzle 200.
In some embodiments, the dispensing nozzle 200 may be embodied as described The
dispensing nozzle 200 may mix the streams of beverage concentrates 310A-L and
flavors 315A-D. The dispensing nozzle 200 may be of conventional design. The
dispensing nozzle 200 may mix the fluid streams via a target or via air mixing and the
like. Other components and other configurations may be used herein.
[052] The beverage concentrates and flavors may be convention single brand
concentrates or flavor concentrates. A number of beverage concentrates and flavors
may be available to produce a number of standard core beverages, flavor modified
beverages, or blended beverages. The beverage concentrates and flavors may have
varying levels of concentration. Alternatively, the beverage concentrates and/or flavors
may be separated in macro-ingredients and micro-ingredients. Generally described, the
macro-ingredients may have reconstitution ratios in the range of about 3: 1 to about
6 : 1. The viscosities of the macro- ingredients typically range from about 100
centipoise or higher. Macro-ingredients may include sugar syrup, HFCS (High Fructose
Corn Syrup), beverage base concentrates, juice concentrates, and similar types of
fluids.
[053] The micro-ingredients may have a reconstitution ratio ranging from
about ten to one (10:1), twenty to one (20:1), thirty to one (30:1), or higher.
Specifically, many micro-ingredients may be in the range of fifty to one (50: 1) to three
hundred to one (300: 1). The viscosities of the micro-ingredients typically range from
about 1 to about 100 centipoise or so. Examples of micro-ingredients include natural
and artificial flavors; flavor additives; natural and artificial colors; artificial sweeteners
(high potency or otherwise); additives for controlling tartness, e.g., citric acid,
potassium citrate; functional additives such as vitamins, minerals, herbal extracts;
nutraceuticals; and over-the-counter (or otherwise) medicines such as acetaminophen
and similar types of materials. The acid and non-acid components of non-sweetened
beverage baser component concentrates also may be separated and stored individually.
The micro-ingredients may be liquid, powder (solid), or gaseous form and/or
combinations thereof.
[054] The operating system 1201 may also include a carbon dioxide source
356 positioned within the housing 110. The carbon dioxide source 356 may be a
carbon dioxide tank and the like. The carbon dioxide source 356 may have any size,
shape, or configuration. Multiple carbon dioxide tanks may be used. An external
carbon dioxide source 356 may also be used. A tank sensor 1015 may be used to detect
the presence of the carbon dioxide source 356 within the housing 110. The tank sensor
1015 may be of conventional design and may be in communication with the controller
120. A pressure regulator 341B may be used with or downstream of the carbon dioxide
source 356. The pressure regulator 341B may be of conventional design.
[055] As shown in FIG. 4, the carbon dioxide source 356 may be introduced
into the housing 110 utilizing a quick connect mechanism 351. To prevent over
pressure within the operating system 1201, the carbon dioxide source 356 may include
a pressure regulator 34IB to detect pressure received from the carbon dioxide source
356. In one example, the pressure regulator 341B may be in communication with the
controller 120. In addition to or as an alternative to the pressure regulator 341B, the
carbon dioxide source 356 may employ a throttling system 352 within the quick
connect mechanism 35 1 to prevent over pressure within the operating system 1201 . In
the depicted example, the quick connect mechanism 351 is shown and described for a
carbon dioxide source 356 with a vertical outlet. In an alternative embodiment, the
quick connect mechanism 351 may be used for a carbon dioxide source 356 embodying
a right-angled outlet. In other examples, the quick connect mechanism 351 may be
used for carbon dioxide sources that may otherwise have outlets that are not vertical.
[056] To initiate flow from the carbon dioxide source 356, the controller 120
may be in communication with a lever 353 within the quick connect mechanism 35 1 to
press a release pin 354 down within the carbon dioxide source 356 to provide an
opening 355. The controller 120 may communicate to the lever 353 via a solenoid
switch or any other electromechanical devices known in the art. The release pin 354
may include a schrader valve. The opening 355 may enable carbon dioxide gas to flow
to downstream via the throttling system 352. In certain examples, the throttling system
352 may be constructed to restrict the flow rate of the gas coming out of the carbon
dioxide source 356 under high pressure to a reduced flow rate once the release pin 354
is pressed within the carbon dioxide source 356. The throttling system 352 may
provide a restriction to the gas flow rate to control the gas flow rate and prevent over
pressure within the operating system 1201. The throttling system 352 may include a
piston, a metal disk with a predetermined orifice, a butterfly valve, or any other
electromechanical obstructions known in the art.
[057] The operating system 1201 may also include refrigerated carbonator 360
positioned within the housing 110. The refrigerated carbonator 360 may include a tank
head 3000. The refrigerated carbonator 360 may receive carbon dioxide at the tank
head 3000 from the carbon dioxide source 356 via the pressure regulator 341B. The
carbon dioxide regulator 341B and/or the throttling system 352 may be in
communication with a stinger tube 361 . The stinger tube 361 may extend into the
refrigerated carbonator 360 towards a bottom end thereof. A pressure relief valve 365
may be positioned on the refrigerated carbonator 360. The pressure relief valve 365
may be of conventional design. Other components and other configurations may be
used herein.
[058] The refrigerated carbonator 360 may include an outer insulating jacket
391, a plain water reservoir 355 concentric within the outer insulating jacket 391, and a
carbonated water reservoir 395 concentric within the plain water reservoir 355. The
outer insulating jacket 391 may be partially cylindrical in shape and may have any
length or diameter. The outer insulating jacket 391 may be made from an outer layer of
an acrylic or similar types of materials and inner layer of an insulating material with
good thermal insulating characteristics. Other types of materials may be used herein.
The refrigerated carbonator 360 may include a carbonated water carbonated water
recirculation loop 20. The carbonated water recirculation loop 20 may extend from a
recirculation dip tube 367 at the tank head 3000 that draws carbonated water from the
bottom of the carbonator 360, to recirculation regulator 34 1C, to recirculation pump
331, and back through a water inlet dip tube 366. The water inlet dip tube 366 may
include a nozzle configured to add velocity to the water for increased agitation therein.
The water inlet dip tube 366 may have an area of narrowing diameter and the like.
Furthermore, the water inlet dip tube 366 may have one or more holes along the length
of the water inlet dip tube 366 and angled with respect to the inside surface of the
carbonated water reservoir 395 to promote circulation of the carbonated water across an
ice bank 385 within the carbonated water reservoir 395. Ensuring sufficient circulation
may prevent the ice bank 385 from forming non-uniformly throughout the carbonated
water reservoir 395. The recirculation regulator 34 1C may be of conventional design.
Alternatively, any type of flow control device may be used herein. The carbonated
water recirculation loop 20 may promote good carbon dioxide saturation in the water
and heat exchange with the ice bank 385 in the carbonated water reservoir 395.
[059] The carbonated water reservoir 395 may be positioned within the outer
insulating jacket 391 and may define a plain water reservoir 355 there between. The
carbonated water reservoir 395 may have any length or diameter. The carbonated
water reservoir 395 may be made out of metals and other types of materials with good
thermal transmittance characteristics. Likewise, the plain water reservoir 355 may
have any length, diameter, or volume. The carbonated water reservoir 395 may be a
pressurized tank for mixing water and carbon dioxide therein. The plain water
reservoir 355 may surround the carbonated water reservoir 395. The plain water
reservoir 355 may be in communication with a water inlet 2 via a water input 50, threeway
valve 341A, and fill pump 325. The fill pump 325 may of conventional design.
The water inlet 2 may be supplied from municipal water. Conversely, the water inlet 2
may be supplied from a water reservoir external to the housing 110. The water input 50
may extend through the outer insulating jacket 391 to the bottom of the plain water
reservoir 355. Furthermore, the water input 50 may have an angled hole to promote
circulation of the water within the plain water reservoir 355. Ensuring sufficient
circulation may prevent the ice bank 385 from forming non-uniformly in the plain
water reservoir 355. The water input 50 may be located at, or near the bottom of the
plain water reservoir 355, opposite a water output 70, to promote sufficient heat
exchange between the plain water and the ice bank 385 within the plain water reservoir
355.
[060] The water output 70 may be located near the top of the plain water
reservoir 355. In an alternative embodiment, the water output 70 may be located on the
opposite side of the plain water reservoir 355 as the water input 50 to further promote
sufficient heat exchange between the plain water and the ice bank 385. Where the
water output 70 is located on the opposite side of the plain water reservoir 355, the
water may have to flow around the carbonated water reservoir 395 and across the ice
bank 385 to reach the outlet 70. The water output 70 may extend from the plain water
reservoir 355 to a dispenser 200 via the output regulator 341D. The output regulator
34 ID may be of conventional design. Alternatively, any type of flow control device
may be used herein.
[061] The refrigerated carbonator 360 may also include a water input 364 at
the tank head 3000 for supplying plain water to the carbonated water reservoir 395.
The water input 364 may be in communication with the water inlet 2 via a water input
40, three-way valve 341A, and fill pump 325. The water input 364 may extend through
the refrigerated carbonator 360 into the carbonated water reservoir 395. The water
input 364 may include a water nozzle configured to add velocity to the water for
increased agitation therein. The water input 364 may have an area of narrowing
diameter and the like. Other components and other configurations may be used herein.
[062] The refrigerated carbonator 360 may include a number of concentrate
coils positioned within the plain water reservoir 355 and carbonated water reservoir
395 to chill the beverage concentrate therein. The concentrate coils may have any size,
shape, or configuration. A first concentrate coil 60 may be in communication with the
beverage concentrates 3 1OA and B to chill the beverage concentrates 3 1OA and B, a
second concentrate coil 6 1 may be in communication with the beverage concentrates
3IOC and D to chill the beverage concentrates 3IOC and D , a third concentrate coil 62
may be in communication with the beverage concentrates 310E and F to chill the
beverage concentrates 310E and F, a fourth concentrate coil 63 may be in
communication with the beverage concentrates 310G and H to chill the beverage
concentrates 310G and H, a fifth concentrate coil 64 may be in communication with the
beverage concentrates 3101 and J to chill the beverage concentrates 3101 and J, and a
sixth concentrate coil 65 may be in communication with the beverage concentrates
310K and L to chill the beverage concentrates 310K and L. The beverage concentrates
may be paired. For example, 310A and 310B may be the same brand. Any number of
concentrate coils may be used herein.
[063] The concentrate coils may extend through the refrigerated carbonator
360 via a number of concentrate ports extending through. The beverage concentrates
310A-L thus may be pumped via the concentrate pumps 305 into the refrigerated
carbonator 360 so as to be chilled within the concentrate coils 60, 61, 62, 63, 64, 65,
and then onto the dispensing nozzle 200. A plurality of concentrate coils may extend
into the carbonated water reservoir 395, whereas the remaining concentrate coils may
extend into the plain water reservoir 355. As shown in FIG. 1, concentrate coils 60 and
6 1 extend into the plain water reservoir 355, whereas concentrate coils 62, 63, 64, and
65 extend into the carbonated water reservoir 395. Other components and other
configurations also may be used herein.
[064] The refrigerated carbonator 360 may include a refrigeration unit for
maintaining an appropriate temperature to develop an ice bank 385 that extends into
both the carbonated water reservoir 395 and the plain water reservoir 355. The
refrigeration unit may include a compressor 371, a condenser 339, and an evaporator
unit 381. The evaporation coils of the evaporator unit 381 may be positioned within
the plain water reservoir 355 about the carbonated water reservoir 395. The evaporator
unit 381 may have any size, shape, or configuration. Other types of cooling devices
may also be used herein. The ice bank 385 may have an ice bank maximum-minimum
level sensor 1035. Upon receiving an indication of a maximum fill level from the ice
bank maximum-minimum level sensor 1035, the controller 120 may turn off the
compressor 371 . Likewise, upon receiving an indication of a minimum fill level from
the ice bank maximum-minimum level sensor 1035, the controller 120 may turn on the
compressor 371.
[065] The refrigerated carbonator 360 may also include a temperature sensor
1010, a level sensor 1020, a tank pressure sensor 386, and other types of sensors
located at the tank head 3000. The level sensor 1020 may be configured to detect the
maximum carbonator water fill level within the carbonated water reservoir 395. The
tank pressure sensor 386 may be configured to detect the maximum carbonator pressure
fill level within the carbonated water reservoir 395. In operation, after a beverage has
been dispensed or it is otherwise determined that the carbonated water needs to be
replenished, the three-way valve 341A may be switched so as to direct plain water from
the plain water inlet 2 to water input 40 and into the carbonated water reservoir 395 via
the water input 364 until the level sensor 1020 detects that the water level has reached
the maximum fill level. A flow meter 103 may be used on the carbonated water line 10
and elsewhere. The sensors 1010, 1020 and the flow meter 1030 may be of
conventional design. The sensors 1010, 1020 and the flow meter 1030 may be in
communication with the controller 120. Other components and other configurations
may be used herein.
[066] In use, the beverage concentrates 310A-L and the flavors 315A-D may
be positioned within the housing 110. Likewise, the carbon dioxide source 356 may be
positioned within the housing 110. The fill pump 325 may fill the plain water reservoir
355 and the carbonated water reservoir 395 of the refrigerated carbonator 360 with
water while the recirculation pump 331 starts to circulate carbonated water through the
carbonated water reservoir 395 via the carbonated water recirculation loop 20.
Likewise, the refrigerated carbonator 360 therein may be further chilled via the
refrigeration unit, which includes a compressor 371, a condenser 339, and an
evaporator unit 381.
[067] Once the contents within the carbonated water reservoir 395 and
recirculation pump 331 have reached a predetermined temperature as detected by the
temperature sensor 1010, the operating system 1201 may allow a consumer to select a
beverage via the consumer input device 130. Where at least one of the beverage
concentrates 310A-L and the flavors 315A- D have been exhausted, sensors 1050,
1060, 1070, 1080, 1090, 2000, 2010, 2020, 2030, 2040, 2050, and 2060 may detect a
no or low flow condition. The sensors may communicate a corresponding signal to the
control device 120 when a no or low flow condition is detected. Alternatively, the
beverage concentrates 310A-L and flavors 315A- D may be determined to have been
exhausted by the control device 120 calculating the number of pulses that the pumps
305 have been cycled. Where an individual beverage concentrate or flavor has been
exhausted the control device 120 may switch to a corresponding remaining beverage
concentrate. For example, the control device 120 may determine that the beverage
concentrate 310A has been exhausted based on the input from sensor 1050 or based on
the pump pulse count. The beverage concentrate 310B may then be used in place of
beverage concentrate 310A via a bank switching mechanism. This may enable a
selected beverage to still be available prior to replacing the exhausted beverage
concentrate. The control device 120 may generate an indication that a beverage
concentrate has been exhausted. For example, upon the control device 120 determining
that a beverage has been exhausted, the control device 120 can output a signal to a user,
for instance via the user interface such as 130.
[068] FIG. 2 is a schematic view of a user interface 130. The input device 130
may be a conventional touchscreen 140 or a similar type of user input device.
Alternatively, mechanical devices, electro-mechanical device, audio devices, optical
devices, and the like also may be used herein. In this example, the touchscreen 140
may have a number of icons representing a number of beverages and a number of
flavors. A first beverage icon 150 may represent a first beverage, a second beverage
icon 170 may represent a second beverage, a third beverage icon 190 may represent a
third beverage, and a fourth beverage icon 210 may represent a fourth beverage. Any
number of beverage icons and beverages may be used herein. The touchscreen 140
may also include a number of flavor icons representing a number of flavors. A first
flavor icon 230 may represent a first flavor, a second flavor icon 250 may represent a
second flavor, a third flavor icon 270 may represent a third flavor, and a fourth flavor
icon 290 may represent a fourth flavor. Any number of flavor icons and flavors may be
used herein. Furthermore, the beverage icons may appear on a different page than the
flavor icons.
[069] Where an individual beverage concentrate or flavor has been exhausted
the control device 120 may switch to a corresponding remaining beverage concentrate.
For example, sensor 1050 may detect a no or low flow condition in the beverage
concentrate 3 1OA. Alternatively, the control device 120 may determine that the
concentrate pump 305 has been pulsed a maximum number of times for beverage
3104A. The beverage concentrate 310B may then be used in place of beverage
concentrate 310A. Upon receipt of an indication from the control device 120 that a
concentrate has been exhausted within the beverage concentrates 310A-L or flavors
315A-D, the control device 120 can output a signal to a user via the user interface 130.
The user interface 130 may indicate sold out or exhausted concentrate condition by
highlighting 150A the corresponding icon, providing a small indication 170A over the
corresponding icon, or other visual indicators in association with a sold-out brand or
flavor on the user interface. A small indication 170A may include an illuminated dot,
triangle, or other smaller shapes that do not encompass an entire beverage or flavor
icon. Where the corresponding beverage concentrate or flavor has been replenished, a
sensor may detect a replenished beverage concentrate or flavor. Subsequently, the
control device 120 may remove the signal to a user via the user interface 130. The
sold-out indication on the user interface may enable a crewmember, a crew manager, a
retail operator, manager, or a service technician to quickly identify which brands that
may need to be replaced. This may be particularly useful during a period of high
volume users in a short period of time, such as prior to a lunch rush.
[070] FIG. 3 is a flow chart setting forth the general stages involved in a
method 400 consistent with an embodiment of the disclosure for dispensing multiple
flavored brands. Method 1400 may be implemented using an operating system 1201
positioned within a housing 110 as is described in more detail above with respect to
FIG. 1-2. Ways to implement the stages of method 1400 will be described in greater
detail below.
[071] Method 1400 may begin at starting block 1405 and proceed to stage 310
where a refrigerated carbonator 360 may receive a beverage selection at the user
interface 130. For example, the user may select between an assortment of beverages by
touching a first beverage icon 150, second beverage icon 170, a third beverage icon
190, a fourth beverage icon 210. Any number of beverage icons of beverages may be
used herein. For instance, the user may scroll by sliding his or her finger across the
display and make selections by tapping the desired icon.
[072] A second user input may be received at the user interface 130. For
example, after selecting the desired core brand the user may be presented with a menu
for various flavors of that core brand. For example, the user may select between an
assortment of flavors by touching a first flavor icon 230, second flavor icon 250, a third
flavor icon 270, a fourth flavor icon 290. Any number of flavor icons of flavors may
be used herein. For example, if the user selects Coca-Cola®, then a second menu may
appear displaying Coca-Cola®, Vanilla Coke®, Cherry Coke®, and the like. Third
user input for dispensing a beverage may include a pour button on touchscreen, lever,
push-to-pour button, or other mechanical or electrical input separate from the
touchscreen.
[073] Method 1400 may continue to stage 1420 where a sold out condition of
at least one beverage concentrate or flavor may be detected. Upon receipt of an
indication from the control device 120 that a sold out condition exists within the
beverage concentrates 310A-L or flavors 315A-D, the control device 120 can output a
signal to a user via the user interface 130. The sold-out indication on the user interface
130 may enable a crewmember, a crew manager, a retail operator, manager, or a
service technician to quickly identify which brands or flavors that may need to be
replaced.
[074] Method 1400 may continue to stage 1430 where the user interface 130
may indicate a sold out condition of the at least one of the beverage concentrate or the
flavor. The indication may be accomplished by highlighting 150A the specific icon,
providing a small indication 170A over the specific icon, or other visual indicators in
association with a sold-out brand or flavor on the user interface. A small indication
may include an illuminated dot, triangle, or other smaller shapes that do not encompass
an entire beverage or flavor icon. Where the specific beverage concentrate has been
replenished, a sensor may detect a replenished beverage concentrate or flavor.
Subsequently, the control device 120 may remove the signal sent to a user via the user
interface 130.
[075] Furthermore, upon detecting an individual beverage concentrate or
flavor has been exhausted a control device 120 may switch to a corresponding
secondary beverage concentrate or a corresponding secondary flavor in stage 1440.
For example, sensor 1050 may detect a sold out condition in the beverage concentrate
31OA. The beverage concentrate 31OB may be used in place of beverage concentrate
310A via a bank switching mechanism. This may enable a selected beverage to still be
available prior to replacing the exhausted beverage concentrate.
[076] While the present disclosure has been described in terms of particular
preferred and alternative embodiments, it is not limited to those embodiments.
Alternative embodiments, examples, and modifications which would still be
encompassed by the disclosure may be made by those skilled in the art, particularly in
light of the foregoing teachings. Further, it should be understood that the terminology
used to describe the disclosure is intended to be in the nature of words of description
rather than of limitation.
[077] Those skilled in the art will also appreciate that various adaptations and
modifications of the preferred and alternative embodiments described above can be
configured without departing from the scope and spirit of the disclosure. Therefore, it is
to be understood that, within the scope of the appended claims, the disclosure may be
practiced other than as specifically described herein.
