Definitions
- a wide variety of different postmix dispensers are known, including those having multiflavor valves and those having the selector buttons and nozzle at a notched corner of the cabinet. It is also known to have a dispensing system in which some parts of the dispenser are located above the counter and some parts are located below the counter.
- the dispense module 14 has a longer sidewall and shorter frontwall and includes a dispense module housing 69, a dispense section 70, a separate hollow section 72, and a lid 74.
- the hollow section 72 is generally U-shaped with an opening 76 in its rear wall 78 to accommodate the syrup pumps 36, in the modes of operation shown in Figs. 1 and 2.
- the hollow section 72 is attached by bolts and nuts 80 to the refrigeration module housing 26.
- Fig. 12 shows another embodiment wherein the upper portion 82 of the dispense section 70 of the dispense module 14 is used by itself, by connecting it above a sink, such as under an existing cabinet (it can alternatively be wall mounted).
- the refrigeration module 212 When the refrigeration module 212 is attached to the dispense module 214, air flows into the refrigeration module 212 through the air inlet vents 229, through the condenser 246, and out through the air outlet vents 230.
- the refrigeration module 212 may often be located in a confined space and the air flow could go directly from the air outlet vents 230 into the inlet vents 229. This would cause the compressor motor to run more often, wear out more quickly and could raise the drink temperature. Therefore, in this situation, the inlet vents 229 are covered by a plate 235 (of metal, wood or plastic, for example) and the air then flows in the air inlet vents 233 and out the air outlet vents 230. It has been found that this arrangement with the plate 235 avoids the problem mentioned above.
- the entire unit 257 can be easily slid out directly upwardly out of the dispenser 210 (after removing the lid 228).
- This also provides easy access to the agitator motor 255 and other components including a transformer mounted adjacent the motor 255.
- This feature is important because the dispenser 210 does not have a separate bonnet (or top half of the housing) as do many countertop dispensers, so access has to be through the top opening when the lid is removed.
- the dispenser 210 is small and compact, the internal components are easily accessible while the outside shell has a smooth, clean, and continuous surface providing a large advertising surface and a neat appearance.
- Figs. 16 and 17 show the water and syrup circuits for the dispenser 210, both when the two modules are connected and when they are separated.
- Figs. 16 and 17 both show a cooling coil 271 in the soda line 273 downstream from the carbonator tank 258.
- the dispenser 210 also has the precooling coil 66 as shown in Figs. 9 and 10. This precooling coil 66 allows the use of a lower CO2 pressure in the carbonator tank 258 and in fact the use of the same pressure in the tank 258 that is needed to operate the syrup pumps 36. This allows for the elimination of a separate CO2 pressure regulator for the carbonator tank 258 and allows for the operation of the dispenser 210 with only the single CO2 regulator 275 on the CO2 cylinder 276.
- Fig. 17 also shows a multiflavor nozzle 300, solenoid valves 285, flow controls 287, flow washers 289, a chilled water bath 291, the carbonator tank 258, the CO2 cylinder 276, the pressure regulator 275, the syrup pumps 36, the carbonator pump 293, and the plain water line 295.
- Fig. 16 shows the same components except for the recirculating soda system which is not used when the dispense and refrigeration modules are connected.
- Figs. 18-21 show the preferred nozzle 300 of the present invention used in the dispenser 210, including a nozzle body 302 and a spout 304.
- the nozzle body has a water passageway 306 therethrough and four separate syrup passages, one of which 308 is show in Fig. 20.
- the water goes straight down from a water inlet port 309 through an axial passage 310 in the nozzle body until it splits into two radial passages 312 and 314 at right angles to the axial passage 310.
- the passages 312 and 314 exit into an annular groove 316 from which the water hits the spout 304 and then flows down and out the spout opening 318.
- the four syrup passages are similar to each other and each start at a respective one of four separate syrup inlet ports 330, 331, 332 and 333 and continue through the nozzle body as described below for passage 308.
- the syrup passage 308 splits into two separate passages 320 and 322 and exit out two separated, spaced-apart, outlet openings 324 and 326 in a bottom wall 328 of the nozzle body 302.
- This nozzle provides improved mixing, less stratification in the beverage cup, and reduced flavor carryover. Any known method can be used to connect the spout to the nozzle such as a bayonet connection using two flanges on the spout.
- the hollow section 372 of the dispense module 214 referred to as the pump wrap because it covers the syrup pumps 36, can be easily removed to provide access to the syrup pumps by simply removing two screws 373 at the top thereof, and then lifting up to clear two pins from two holes at the lower end of the section 372.
- the same pin-hole arrangement is used to connect the drip tray unit 375 to the section 372 when the modules are separated.
- the pin-hole arrangement is shown in Fig. 25.
- the hollow section 372 has two holes 500 and 502 and the refrigeration module has two mating pins 504 and 506.
- the drip tray has two pins 508 and 510 and the refrigeration module has two mating holes 512 and 514. When the two modules are separated, the pins of the drip tray connect with the holes 500 and 502 in the hollow section 372.
- the dispenser 210 can include legs, or not, as desired. If the refrigeration unit includes legs, then legs are also used on the dispense unit but preferably on the distal end thereof.
- a conduit 308 that goes into the multiflavor valve has a fitting 310 with an o-ring 312 and a groove 314.
- the end of a flexible line 316 includes a mating coupling 318 that slides over the fitting 310.
- a pin 320 slides through two holes 322 in the coupling 318 and into the groove 314 to hold the line to the conduit 308.
- the valve 110 is held to the wall 326 by sliding the conduit 308 down in the Keyway 328 to lock the wall 326 between the fitting 310 and the rear of the valve 110.
- the valve 110 is not shown in Fig. 23.
- the connections to the refrigeration module at the other end of the python are made the same way, as shown in Fig. 24.
- buttons can be located permanently in both places, with a cover over the ones not being used.
- the term "convertible” means a dispenser that can be converted in size and shape to fit in different available spaces.
- the hollow section 142 can be part of the dispense section with a hollow section like 72 left connected to the refrigeration module.
- the long lines can be stored in the hollow section 72. This would make the conversion easier and could avoid the need for a conversion kit.
- the dispense module can be made as a one-piece unit, and when separated from the refrigeration module, an additional, separate panel could be added to the open side that faces the refrigeration module when connected thereto.
- the refrigeration system is preferably mechanical although a cold plate could be used.

Abstract
Description
- This invention relates to counter top, postmix beverage dispensers, and in particular to a low-cost, compact, versatile, multiflavor, convertible beverage dispenser.
- A wide variety of different postmix dispensers are known, including those having multiflavor valves and those having the selector buttons and nozzle at a notched corner of the cabinet. It is also known to have a dispensing system in which some parts of the dispenser are located above the counter and some parts are located below the counter.
- EP-A-319348 discloses a beverage dispenser having the features of the opening part of claim 1.
- The present invention is characterised by the features of the characterising part of claim 1.
- In a preferred form the invention provides a low cost, compact, versatile, multiflavor, postmix, convertible beverage dispenser which can be oriented in any one of several different ways to fit into any available space in an outlet. If an outlet has room for a dispenser, this dispenser will fit. This advantage can be used to reduce the inventory of different sizes of dispensers presently needed to accommodate different outlets. This dispenser can be oriented frontways or sideways by an easy change in the location of the selector buttons. Alternatively, this unitary dispenser can be separated into a dispense module and a refrigeration module. The refrigeration module can be located below the counter and the dispense module can fit into a very small place on a counter. This convertible dispenser can be used with figals or can be used with bag-in-box with built-in syrup pumps. In addition, this convertible dispenser can be easily modified to dispense different numbers of beverages.

- Referring now to Figs. 1 to 10, a
dispenser 10 of the prior art includes arefrigeration module 12 and aseparate dispense module 14 which is removably attached to the refrigeration module. In the preferred embodiment shown, thedispenser 10 has asingle multiflavor valve 16 with a single mixing and dispensingnozzle 18 for dispensing a beverage into a cup 19 (Fig. 7),carbonated water line 22 and foursyrup lines 24. The dispensingvalve 16 is in a notched corner of thedispenser 10 with the buttons on either of the adjacent walls. - The
dispenser 10 as shown in the drawings is set up for use with bag-in-box syrup containers (not shown), although it can also be used with figals (not shown). - The
dispenser 10 can be set up for operation on a countertop 11 (see Fig. 3) in any one of the three modes of operation shown in Figs. 1, 2 or 3. To convert between the modes shown in Figs. 1 and 2, it is only necessary to move thebuttons 20 to change places with thepanel 96. To convert from either the Fig. 1 or 2 mode to the Fig. 3 mode, a small conversion kit is used. Thedispense module 14 is separated from therefrigeration module 12 and slightly rearranged (Fig. 7), the longer water and syrup lines are attached, a different splash plate (flat instead of L-shaped) is attached, and preferably a recirculatingpump 134 and line are connected. - The
refrigeration module 12 includes ahousing 26, alid 28, an ice-water tank 30, a refrigeration unit 32, acarbonator unit 34, and foursyrup pumps 36 mounted on thesidewall 38. Thelid 28 has air inlet vents 13 in a front portion thereof andair outlet vents 15 in a rear portion thereof. - The refrigeration unit 32 is mounted on a
refrigeration deck 40 that sits on top of thetank 30. The unit 32 includes the usual equipment such as anevaporator coil 42, an agitator 44, condensercoils 46m compressor 48,ice bank control 50, andcooling fan 52 operated by anagitator motor 54, - The
carbonator unit 34 is mounted on acarbonator deck 56 and includes the usual carbonator equipment including acarbonator tank 58, a water pump andmotor 60,level controller 62, andCO₂ inlet 64. - The
refrigeration module 12 also includes the usualwater cooling coils 66 and four separatesyrup cooling coils 68. The water goes to thepump 60, then to thewater cooling soils 66, then to thecarbonator tank 58 and then to themultiflavor valve 16. The syrup goes from a bag-in-box container (not shown) to one of the foursyrup pumps 36, to asyrup cooling coil 68, and then to themultiflavor valve 16. Eachpump 36 has a CO₂ inlet, a syrup inlet and a syrup outlet, for example, for a CO₂ operated pump. - The
dispense module 14 has a longer sidewall and shorter frontwall and includes adispense module housing 69, adispense section 70, a separatehollow section 72, and alid 74. Thehollow section 72 is generally U-shaped with an opening 76 in itsrear wall 78 to accommodate thesyrup pumps 36, in the modes of operation shown in Figs. 1 and 2. Thehollow section 72 is attached by bolts andnuts 80 to therefrigeration module housing 26. - The
dispense section 70 includes separate upper andlower portions shaped splash guard 88 in Figs. 1 and 2, and aflat splash guard 90 in Fig. 3. The lower portion is the drip tray unit and includes the drip tray 85 and thecup rest 86. The drip tray unit can be connected to thehollow section 72 and/or to therefrigeration module 12. - The
upper portion 82 includes ashell 92 having an open top 93 and an openrear wall 94. Theshell 92 is bolted to both therefrigeration module housing 26 and to thehollow section 72 by bolts and nuts 80. - The
upper portion 82 includes theselector buttons 20, apanel 96, and thesingle multiflavor valve 16. In the arrangement of Fig. 1 when thedispenser 10 is arranged frontways, theselector buttons 20 are placed in an opening 100 in afrontwall 98 of the dispensemodule 14, and thepanel 96 is placed in anopening 102 in the sidewall 104. In the mode of operation shown in Fig. 2, theselector buttons 20 are placed in thesidewall opening 102 and the panel 996 is placed in the frontwall opening 100. In the separated arrangement of Fig. 3, theselector buttons 20 are placed in thesidewall opening 102 as in Fig. 2. - The manner of changing the
selector buttons 20 andpanel 96 will now be described. theopenings 100 and 102 are identical in size and the buttons and panel can be handled through the open top 93 (with thelid 74 off). Each of the panel and buttons use connected to anidentical mounting plate 106, so a description of one will suffice. Theplate 106 has aflange 108 along its bottom edge that fits in a groove, and the plate has asingle slot 105 centrally located in its top edge to receive abolt 107 connected to the wall and on which awing nut 109 is attached. The wires from the solenoids of theflow control modules 110 to thebuttons 20 are flexible and easily allow movement of the buttons from one wall to the other. - The
multiflavor valve 16 will now be described. Thevalve 16 includes thesingle nozzle 18 and a plurality of separate, identicalflow control modules 110, shown in Fig. 10. One of theflow control modules 110 is for carbonated water an there are fourseparate syrup modules 110, one for each of four syrups. Awater line 112 extends from the waterflow control module 110 to a central opening in thenozzle 18, while the foursyrup lines flow control modules 110 to a respective one of the circumferentially arrangedopenings 116 in the top of thenozzle 18. - Referring to Fig. 8, each of the
flow control modules 110 includes abody 120 and aliquid passageway 122 therethrough from aninlet port 124 to an outlet port 126. A standard piston-spring flow control 128 is located in the passage. A solenoid controlled valve 130 (including a solenoid, an armature, and a valve element movable onto and off of a valve seat) controls the on-off flow through themodule 110. An advantage of this module is the fact that the inlet and outlet ports are on opposite faces and have passageways whose axes are parallel, to provide ease of installation. - The operation of the two arrangements shown in Figs. 1 and 2 will thus be clear from the above description. If only a very small countertop space is available, then the
dispenser 10 can be converted to a two-piece unit shown in Fig. 3 with only the very narrow dispense module placed on top of the countertop 11. - This conversion from a one to two-piece unit can be easily done in the field with the aid of a small break-away conversion kit containing the long water and
syrup lines 132, arecirculating water pump 134 to be mounted on therefrigerator module housing 26, and aflat splash plate 90. To do the conversion, the lids are removed, the bolts andnuts 80 are removed, therecirculating water pump 134 is mounted on thehousing 26, and thelines 132 are installed. In addition, the twosections nuts 80 as shown in Fig. 10. In this way, the openings in their rear walls are facing each other and the dispense module has a smooth, clean, exterior surface. The drip tray is not connected to theshell 92, but its is connected to a drip tray support that is connected to thehollow section 72 and that extends under bothsections hollow section 70 and then reconnected to extend under the drip tray in Fig. 3. - Fig. 9 shows the standard set up for the water line for the Figs. 1 and 2 modes of operation, and Fig. 10 shows the additional recirculating water line set up for the Fig. 3 mode of operation. This provides cold water for the dispenser at all times.
- Fig. 11 shows a dispense
module 140 according to another embodiment similar to Fig. 3 except that thehollow section 72 is replaced (along with a different lid and drip tray support) with a differenthollow section 142 having much less depth than doessection 72. This embodiment would be used where only a very small countertop space is available. - Fig. 12 shows another embodiment wherein the
upper portion 82 of the dispensesection 70 of the dispensemodule 14 is used by itself, by connecting it above a sink, such as under an existing cabinet (it can alternatively be wall mounted). - Figs. 13-25 show a preferred embodiment of a
convertible dispenser 210 of the present invention. Thedispenser 210 is similar to thedispenser 10 described above with the following differences described below with reference to Figs. 13-25. - Figs. 13 and 14 show the air vent arrangement of the
dispenser 210. Thedispenser 210 includes alid 228 having air inlet vents 229 and air outlet vents 230 in a front portion and in a rear portion, respectively, of thelid 228. Therefrigeration module 212 includes air inlet vents 233 in the upper portion of thesidewall 238. - When the
refrigeration module 212 is attached to the dispensemodule 214, air flows into therefrigeration module 212 through the air inlet vents 229, through thecondenser 246, and out through the air outlet vents 230. When themodules refrigeration module 212 may often be located in a confined space and the air flow could go directly from the air outlet vents 230 into the inlet vents 229. This would cause the compressor motor to run more often, wear out more quickly and could raise the drink temperature. Therefore, in this situation, the inlet vents 229 are covered by a plate 235 (of metal, wood or plastic, for example) and the air then flows in the air inlet vents 233 and out the air outlet vents 230. It has been found that this arrangement with theplate 235 avoids the problem mentioned above. - Figs. 15 and 15A show the preferred arrangement of the
refrigeration module 212 including a condenser 246 (or condenser coil), a coolingfan 252, a coolingfan motor 253, and aseparate agitator motor 255. The fan and fan motor are mounted together as an integral, easily removablemodular unit 257, including abracket 259 which is held in place by twoscrews 261. This arrangement permits the use of a larger condenser than in thedispenser 10. - By simply removing the two
screws 261, theentire unit 257 can be easily slid out directly upwardly out of the dispenser 210 (after removing the lid 228). This also provides easy access to theagitator motor 255 and other components including a transformer mounted adjacent themotor 255. This feature is important because thedispenser 210 does not have a separate bonnet (or top half of the housing) as do many countertop dispensers, so access has to be through the top opening when the lid is removed. Thus, although thedispenser 210 is small and compact, the internal components are easily accessible while the outside shell has a smooth, clean, and continuous surface providing a large advertising surface and a neat appearance. - Figs. 16 and 17 show the water and syrup circuits for the
dispenser 210, both when the two modules are connected and when they are separated. Figs. 16 and 17 both show acooling coil 271 in thesoda line 273 downstream from thecarbonator tank 258. Thedispenser 210 also has the precoolingcoil 66 as shown in Figs. 9 and 10. This precoolingcoil 66 allows the use of a lower CO₂ pressure in thecarbonator tank 258 and in fact the use of the same pressure in thetank 258 that is needed to operate the syrup pumps 36. This allows for the elimination of a separate CO₂ pressure regulator for thecarbonator tank 258 and allows for the operation of thedispenser 210 with only thesingle CO₂ regulator 275 on theCO₂ cylinder 276. - Fig. 17 shows a
recirculating soda line 277, apump 279 and amotor 281 for driving the pump, for use when the modules are separated. It is noted that this recirculating line is entirely downstream from thecarbonator tank 258. This pumping can be controlled to turn on and off as desired but is preferably left on continuously. This recirculating soda line provides a cold drink at all times, even through the refrigeration module is located some distance away from the dispense module. - In Fig. 17, all of the syrup and soda and plain water lines between the separated modules are preferably contained in an insulated python, normally about ten (10) feet long.
- Fig. 17 also shows a
multiflavor nozzle 300,solenoid valves 285, flow controls 287, flowwashers 289, achilled water bath 291, thecarbonator tank 258, theCO₂ cylinder 276, thepressure regulator 275, the syrup pumps 36, thecarbonator pump 293, and theplain water line 295. Fig. 16 shows the same components except for the recirculating soda system which is not used when the dispense and refrigeration modules are connected. - Figs. 18-21 show the
preferred nozzle 300 of the present invention used in thedispenser 210, including anozzle body 302 and aspout 304. The nozzle body has awater passageway 306 therethrough and four separate syrup passages, one of which 308 is show in Fig. 20. The water goes straight down from awater inlet port 309 through anaxial passage 310 in the nozzle body until it splits into tworadial passages axial passage 310. Thepassages annular groove 316 from which the water hits thespout 304 and then flows down and out thespout opening 318. The four syrup passages are similar to each other and each start at a respective one of four separatesyrup inlet ports passage 308. Thesyrup passage 308 splits into twoseparate passages outlet openings bottom wall 328 of thenozzle body 302. This nozzle provides improved mixing, less stratification in the beverage cup, and reduced flavor carryover. Any known method can be used to connect the spout to the nozzle such as a bayonet connection using two flanges on the spout. - The
hollow section 372 of the dispensemodule 214, referred to as the pump wrap because it covers the syrup pumps 36, can be easily removed to provide access to the syrup pumps by simply removing two screws 373 at the top thereof, and then lifting up to clear two pins from two holes at the lower end of thesection 372. The same pin-hole arrangement is used to connect the drip tray unit 375 to thesection 372 when the modules are separated. The pin-hole arrangement is shown in Fig. 25. Thehollow section 372 has twoholes mating pins pins mating holes holes hollow section 372. - The
dispenser 210 does not use the separate drip tray support of thedispenser 10 of Fig. 1. When the two modules are connected, there is preferably no connection between the two sections of the dispense module. - The refrigeration module includes a recess 400 (see Fig. 15A) thereunder and a
notch 402 in thesidewall 404 thereof to accommodate the CO₂ line, the water line and the syrup lines. All of these lines come up through the recess and then under the drip tray and into the hollow section. - The
drip tray unit 410 includes thedrip tray 412 and thecup rest 414. - The
dispenser 210 can include legs, or not, as desired. If the refrigeration unit includes legs, then legs are also used on the dispense unit but preferably on the distal end thereof. - Referring now to Figs. 22-24, these show certain connection details and the
python 300. When the dispense and refrigeration modules are separated, as described above for both the embodiments of Fig. 1 and Fig. 13, the long syrup andwater lines 302 are preferably encased in a long insulated tube orpython 300. Fig. 24 shows the end of the python connected to therefrigeration module 212 and Figs. 22 and 23 show the end connected to the dispensemodule 214. As shown in Fig. 22, the python preferably extends through ahole 303 in thecounter 304 on which the dispenser sits. Fig. 22 shows the fitting 306 for therecirculating soda line 277. - As shown in Fig. 23 a
conduit 308 that goes into the multiflavor valve has a fitting 310 with an o-ring 312 and agroove 314. The end of aflexible line 316 includes amating coupling 318 that slides over the fitting 310. Apin 320 slides through twoholes 322 in thecoupling 318 and into thegroove 314 to hold the line to theconduit 308. Thevalve 110 is held to thewall 326 by sliding theconduit 308 down in theKeyway 328 to lock thewall 326 between the fitting 310 and the rear of thevalve 110. For simplicity, thevalve 110 is not shown in Fig. 23. The connections to the refrigeration module at the other end of the python are made the same way, as shown in Fig. 24. - Fig. 24 also shows the return line and the
pump 279 of the recirculating soda circuit. Thepump 279 is mounted on the lower outside surface of the refrigeration module. The python extends up through thehollow section 72 of the dispensemodule 214. The electrical lines are in thecable 330. - While the preferred embodiment of this invention has been described above in detail, it is to be understood that variations and modifications can be made therein without departing from the spirit and scope of the present invention. For example, while the preferred embodiment described above uses a multiflavor valve, this is not essential; it can alternatively use separate dispensing valves for each beverage or any combination of multiflavor and separate valves. In addition, while the preferred embodiment has been described for use with bag-in-box, it can also be used with figals, in which case the syrup pumps would not be included. The dispenser has been described for use with four separate syrups; this number can easily be changed by changing the number of flow control modules and syrup cooling coils. Other types and arrangements of the selector buttons can also be used. Instead of moving the buttons in switching between the Figs. 1 and 2 arrangements, buttons can be located permanently in both places, with a cover over the ones not being used. As used herein, the term "convertible" means a dispenser that can be converted in size and shape to fit in different available spaces. In addition, when converting to the Fig. 3 mode, or preferably to the Fig. 11 mode, the
hollow section 142 can be part of the dispense section with a hollow section like 72 left connected to the refrigeration module. Also, the long lines can be stored in thehollow section 72. This would make the conversion easier and could avoid the need for a conversion kit. The dispense module can be made as a one-piece unit, and when separated from the refrigeration module, an additional, separate panel could be added to the open side that faces the refrigeration module when connected thereto. The refrigeration system is preferably mechanical although a cold plate could be used. - It will thus be seen that the present invention, at least in its preferred forms, provides a unitary beverage dispenser which can be placed entirely on top of a counter and oriented either frontways or sideways or which can be easily separated into a refrigeration module placed below the counter and a small dispense module placed on top of the counter; and furthermore provides a compact, multiflavor, low cost, versatile, convertible postmix beverage dispenser; and furthermore provides a beverage dispenser that can be easily modified to dispense different numbers of beverages; and furthermore provides an improved flow control module and method for easily changing the numbers of beverages to the dispensed; and furthermore provides a dispenser with two fronts, which can be placed frontways or sideways, and having a small detachable dispense module which can be placed by itself on top of a counter; and furthermore provides a versatile dispenser that can be delivered to an outlet and that will fit in almost any available space; and furthermore provides a single dispenser that is so versatile that it can be used to reduce the need for an inventory of dispensers of different sizes and having a vent arrangement that has one air flow when the refrigeration and dispense modules are attached, and a different air flow when the modules are separated, for improved performance; and furthermore provides a compact dispenser having a one-piece wrap-around shell, a removable lid, a vertically oriented condenser and a modular, easily removable condenser fan-motor unit that, when slid out, provides easy access to the agitator motor and the transformer; and furthermore provides an improved multiflavor nozzle; and furthermore provides a dispenser with an improved water circuit, including one in which the soda or carbonated water is cooled again downstream from the carbonator, and also one in which the soda is continuously recirculated, but not through the carbonator, when the refrigeration module is remote; and furthermore provides a dispenser that is small and compact and yet provides a large, smooth, uninterrupted advertising area while also being less expensive to manufacture; and furthermore provides a dispenser with a pre-cooling syrup coil whereby the syrup pumps and carbonator can use the same pressure, thus eliminating one or two CO₂ pressure regulators.
