Description

t SPECIFICATION

3~S
Background of the Invention The present invention relates to post-mix beverage dispensers which are compact, portable and suitable for use in small offices or small volume locations. More specifically, the present invention relates to a compact post-mix beverage dispenser unit which may be dlsposed on a counter top in the above-mentioned environments and supplied with water rom a pitcher, syrup from disposable sealed packages and C02 for carbonation from refillable containers in a rapid and efficient manner. An accessory attachment may allo~ connection to a building water supply for automatic refi~ of the reservoir.
Heretofore, the majority of comrnercially-available post-mix beverage dispenser units have been designed Eor large volume commercial uses such as in fast food restaurants. Because of these large volume uses, design criteria have emphasized optimum cooling and dispenser speed rather than low unit cost, size and portability.
Although some consideration has been given to cost, size ~0 and portability even in these large volume commercial units, the resulting unit designs are generally far too expellsive, bulky and heavy for small volume use.
Some attempts have been made in the beverage~dispenser industry to reduce the cost, size and weigllt o these units to make them available for use by the general public.
I~owever, the units designed heretofore llave lacked suEficient cooling capacity, dispensing efficiency~
beverage quality and reliability as a trade oEf to achieving the aforementioned low cost, size and portability ~0 needed ~or consumer acceptance.

In order to be accepted by the small volurne consumer, post-mix dispenser units must be easy to se-t up for use, cornpac-t, lightweight, easily repaired, reliable and, most importantly, lnexpensive. In addition, the syrup, water and CO2 supplles must be quickly and easily replenished during use by an unskilled consumer. Although a-ttempts have been made to design post-mix beverage dispenser units possessing the foregoing criteria, the design of such a unit has not been totally achieved prior to the invention described hereinafter.

Detailed Description of the Preferred Embodiments ~5 Cabinetry Construction and General Component ~rrangelnent The cabinetry construction and the general arrangement of the components of the post--mix beverage dispenser unit of the presellt invent;on are illustrated in Figures 1 to 9. Re~errillg to rletail to these FicJures, there is ill~lstrated the post-mix beverage unit of the present ;nvention generally rlesignated lO, including a rnain cabinet portion 12 having front, back, side, top and bottom ~1alls l:l9B3~5 disposed at rignt angles to each other to provide a generally cubicle shape. A front access panel 14 is slidably mounted on the main cabinet portion 12 in suitable tracks to provide selective access to a water entrance chute EC and a syrup supply compartment 34. The front access panel 14 is so configured that it forms a flush corner of the final cabinet design in its closed position.
That is, removable panel 14 has major surfaces parallel to the top, front and left side of the main cabinet portion 12 ~0 so that it wraps around and defines a corner oE the overall cabinet surface of the unit in the closed position. As best illustrated in Figure 7 and Figure 10 in perspective, the front panel 14 is provided with an extension surface in the plane of the top wall of the main cabinet 12 which covers water entrance chute FC in the closed position and may be selectively removed to uncover the entrance chute EC
in an open position. In this position illustrated in Figure 7, the water reservoir WR illustrated in Figure S
can be manuaLly filled with water from a pitcher by pouring water into entrance chute EC. ~owever, it is advantageous to close off entrance chute EC from the atmosphere when water is not being introduced into the unit for sanitary reasons.
A top access panel 16 is provided to cover both the water reservoir WR and carbonator compartment 38 juxtaposed near the back wall of the main cabinet portion 12. This access panel 16 is rectangular in shape and merely lifts oEf from the top of the unit by releasing latch members 16A
~hen access to the ~ater reser~oir WR and carbonator compartment 38 is desired. As ill~strated in Figure 10, the top access panel 16 has an agitator blade AG depending therefrom coupled to an agitator motor secured with access panel 16 having a cornplirnentary shape to the carbonator compartmellt 38 to thereby seal and insulate the carbonator compartment 38 when the rear access panel 16 is secured to the top of the cabinet 12.
The back of the main cabinet 12 is provided with a removable access panel 30 which substantially covers the entire rear wall of the cabinet 12 and has attached thereto a conventional refrigeration condenser 32 for the mechanical refrigeration system of the present invention.
R~moval of this rear access panel 30 and condenser 3~
provides ready access to the water pump and refrigeration components of the present invention which will be described in more detail hereinafter with reference to Figure 6.
An additional access panel 46 is provided in the lower right-hand corner of the dispenser unit of the present invention, as viewed in Figures 1 and 9. In the closed position, panel 46 comprises the lower right-hand corner of the dispenser unit cabinet and is hinged at its back edge to, in effect, form a door which provides access to a C02 COTnpartment 40 for containing a C02 cyllnder 42 and a C2 regulator valve assembly 44. That is, access panel 46 has a right angle configuration whicll conforms to the shape of the lower right-hand corner of the dispenser cabinet to close the C02 supply compartment which is a cut-out in one corner of cabinet 12.
The unique combination of the access panels 14~ 16 and 46 Eac~litates rapid set-up of the post-mi~ beverage system of the present invention and easy access for repair~ With respect to set-up of the system, this may be achieved in the following manner. Front access panel l4 may be slid to a fully opened position, as illustrated in Fiyure 8, and suitable syrup containers SP may be inverted, directing the;r discharge ends downwardly and plugged into sockets 36 (Figure 5). Water may then be manually poured from a pitcher into ~ater entrance chute EC whereby it flows down the chute into wate-r reservoir WR. Front access panel 14 rnay then be closed to the fully closed position illustrated ~11 98395 in Figure 1. In the event that the dispenser unit had an adequate supply of syrup and only water need be added, the access panel 14 could be slid to the partially open position of Figure 7, whereby only water entrance chute EC
were exposed and water added as described above. The CO2 cylinder 42 illustrated in Figure 9 may then be added by inverting the CO2 cylinder to direct the discharge opening downwardly and plugging the same in-to a socket provided on the top surface of CO2 regulator valve assembly 44. Thus, it can be seen that the necessary ~ngxedients to be supplied to the post-mix peverage dispenser can be supplied in a rapid and efficient manner without cumbersome connections by virtue of the unique cabinetry design of the present invention and the plug-in nature of both the syrup packages SP and CO2 cylinder 42 of the present invention.
In further reference to the plug-in nature of the syrup packages SP and the CO2 supply cylinder 42, the specific structure of the valve assemblies and associated containers to be used with the dispenser unit of the present invention are described in prior co-pending ~

The evaporator of the refrigeration system is not illustrated in Figure 6, but can be viewed in the top plan view of Figure 5 as being in the bottorn o~ the ~ater reservoir WR. A water pump WP is disposed in the cabinet just below the fan F The water pumpl as will become more fully apparent hereinafter with respect to Figure 11, is provided to pump water from the water reservoir WR into the carbonator tank CT on demand. The electrical controls for operating the dispensing system of the present invention are housed in a box CB just above the fan F, as illustrated in Figure 6.

Water Supply, Carbonation and Refrigeration Systems The water supply, carbonation and refrigeration systems of the present invention are illustrated in the schematic diagram of Figure 11. The water reservoir WR is connected to the carbonator tank CT through the water pump ~P to pump water on demand from the reservoir to the carbonator tank uncler the supervision of a plurality of ~robes IP, MP and CO and suitable electrical controls witilin box CB. That is, when power is turned on~ pump WP
wil.l rlormally pump t~ater from reservoir WR into carbonator ~5 tank CT. Ilowever, if the water level falls below the rninlmurn level of probe MP, the electrical circuitry provided within control box CB will turn pump WP off and inclicator light 58 on, which signals the need to refill the water reservoir WR.
Probes IP in water reservoir tank WR and carbonator tallk CT sense the build-up oE ice on the ~Jalls the~reof, and when it exceeds a precletermined thickness whereby it covers probes IP, compressor CP is turned off via control box CB

9~
and control Line 64. Probes CO in water reservoir tank WR
and carbonator tank CT are merely the common or yround connections for the circuitry of both probes IP and MP.
Carbonator tank CT also has an additional pair of probes 66 and 68 to initiate or terminate the operation of water pump WP, depending on the level oE water present in carbonator tank CT. That is, when the water level drops below probe 66, pump WP turns on to fill the carbonator tank, and when it reaches a maximum level at the position 0 of probe 68, a signal ;s generated in the control circuitry within box CB via line 50 to turn the water pump WP off.
Th~s, the respective probes in the water reservoir WR and carbonator tank CT are all connected through the electrical control circuitry in control box CB to either turn the water pump WP on and off, or the refrigeration compressor CP via llne 64~
With water present in carbonator tank CT, it operates in a conventional manner by mixing water Erom line 52 and C2 gas frc,m line 56 within the tank C~ and dispensinc3 carbonated water through outlet line 54 to the dispenser valve assembly 18 ~Yherein it is mixed with syrup from the syrup packages SP.
As further illustrated in Figure 11, the mechanical refric]eration system includes a compressor CP, an evaporatoc C, and a conc]enser 32 connected in a closed refrigeration loop. The evaporator C is disposed in contilct with the water reservoir WR to directly chill the water to be pulnped to the carbonator. ~s ;llustrated, a portion of the evaporator C, namely portion 60, wraps aroulld the carbonator tank CT to cool the sarne~ In addition, another portion 62 of evaporator C may pass clirectly behind and in direct contact with cooling bracket ~l8 which surrounds sycup packages SP on three sides to cool the contents of those packages. Thus, the mechan;cal refrigeration systeln of the present invention may be in heat transfer relationship with all of the essential components of the post-mix beverage to be dispensed prioc to the mixing of those cornponents within mixing nozzles 22. This assures that a post-mix beverage is dispensed at a controllable and suitable temperature into cups or containers resting on drip tray 20.
In an alternative ernbodiment, the heat transfer relationship achieved by the refrigeration system of Fiqure 11 and~ more specifically, the portions 60 and 62 of L0 the evaporator coil C in conjunction with the heat transEer bracket ~8, may be accomplished by use of a thermoelectr;c cooling system in combination with a specially designed cold plate therefor which makes a similar type of contact with the carbonator tank and syrup packages. This embodiment of a thermoelectric refrigeration system is illustrated in Figures 12A and 12s.
Referring to Figure 12A, there is generally illustra~ed a thermoelectric module 72, having associated therewith a cold plate 76. Cold plate 76 is so configured that it wraps around water reservoir WR and the syrup supply compartment which houses syrup pack,ages SP. Thus, both the water reservoir WR and the syrup packages SP are c]irectly cooled by the cold plate 76. Also illustrated in L'igure 12A i5 a heat sink 70 on the bottom of the therlnoelectric moclule 72 and an associated fan 74 for removir)g heat from a dispenser cablnet.
Rcferring to Figur~ 12~, there is illustrated a carl)ollator tank c~r, which is also juxtaposed to water reservoir WR and in direct contact with a portion of cold plate 76. Thus, carbonator tank CI' is also in a heat transEerring relationship with cold plate 76 and is directly cooled thel-eby. Accordingly, the dispenser unit has three juxtaposed compartlnerlts housing the water reservoir, syrup packages and carbonator tank, respectively, which are all in direct heat transfer i ' ~IL 11 9~33~ `

relationship with cold plate 76. Thus, as in the mechanical rerigeration system of the present invention, the water reservoir, carbonator t~nk and syrup packages are all directly cooled by the refrigeration system to provide a suitably chilled post-mix beverage.
It should be understood that a preferred embodiment of the dispenser cabinetry and system components of the beverage dispenser of the present invention have been de~scribed herein, but that modifications may be made as would occur to one of ordinary skill in the art without departing from the spirit and scope of the present invention.
For example, the arrangement of the respective rompartments of the cabinetry may be modified within the spirit and scope of the present invention. The terminology of front, back, side and bottom walls is used for descriptive purposes of the preferred embodiment only to define the relative locations of the component parts as illustrated ln the drawinqs, it being recognized that the cabinet may be rotated making the cabinet front and back the sides and vice versa. In addition, the cabinet access panels may be modified slightly within the spirit of the present invention. For example, common panesl could be used to cover adjacent component compartments to reduce the number of panels.
