. BACKGROUND OF THE INVENTI ON
1. Field of the Invention In one aspect, this invention relates to machines for mixing and dispensing two or more fluid components. In a further aspect, this invention relates to machines which are designed to dispense juices.
:' ' .'' ' , .
; 2. DescriPtion of the Prior Art . .One example of a dispenser designed to mix water and -10juice concentrate is disclosed in U.S. Patent 3,323,681 issued to Divette and Harmon. This patent discloses a constant rate pump, e.g., a compressible tube pump, for conveying a constant quantity of juice concentrate to a mixer. A diluent, generally water, is supplied to the mixer at a substantially constant pressure through a mixer control valve which metexs the water to provide the desired product. When the control valve is open, water i8 supplied to the mixer under its own pressure. The flow rate is selected with respect to the constant pumping rate of the concentrate pump. There have been problems with prior art dispensers. Prior art dispensers have been complex in nature and difficult to service when the machine~ became inoperable.
The various components of such dispensers have been generally permanently connected. When one of the components malfunctioned, the entire dispenser had to be deactivated, disassembled, the faulty part replaced, and then reassembled. The result or this complex servicing has been increased servicing co~t to the customer and a substantial downtime when a defective part was discovered. Furthermore, in applications where plural prior art systems were linked together, a defective part in one portion of the machine effectively disabled a number of dispensing stations.
One aspect of the present invention resides in a dispenser for mixing diluent and juice concentrate having means to mix the concentrate and diluent and means to dispense a mixed juice. There is provided a module adapted to be inserted within the dispenser, the module including first connector means adapted for connection to a supply of juice concentrate to allow the concentrate to enter the module with first valving means having an inlet and an outlet, the inlet thereof being connected to the concentrate supply via the first connector means, Pumping means is provided which has the inlet thereof connected to the outlet of the first valving mean~ and is operable upon activation to pump the concentrate at a uniform rate. Second connector means is adapted for connection to a supply of diluent to allow the diluent to enter the module. Flow control means receives the diluent from the ~econd connector means and is operable to regulate the flow of diluent within the module for maintaining the : desired dilution of the concentrate. Second valving means : receives diluent from the flow control means and i~ operable .':, :' upon actuation to allow diluent to flow within the module.
Means defines a mixing chamber and includes means connecting the chamber to the outlet of the second valving means and to the discharge side of the pumping means to receive and mix ~ the ~uice concentrate and diluent. Nozzle means is provided `~ 30 for dispensing mixed juice in a container, and a means is ~ -operative to activate the pumping means and the second valving means to feed concentrate and diluent to the mixing chamber.
According to another aspect of the present invention C cbr/~c . ~ , . . ~, .
-~ 1066675 - there is provided a removable module for use in a device for mixing a pressurized supply of diluent with a gravity supply of liquid beverage concentrate and dispensing same to the atmosphere as a mixed beverage. There is provided means defining a module envelope with mixing means operable upon ' receipt of individual flows of the diluent and concentrate , .
to mix the flows to a homogeneously mixed beverage. First conduit means includes connector means adapted for attachment to a source of diluent external to the envelope and includes means defining a flow path for connecting the pressurized diluent supply with the mixing means. An adjustable flow control means is connected along the diluent flow path between the mixing means and the diluent supply and is operable to ~electively control all of the diluent flow to the mixing means at a constant rate for downstream pressure less than a predetermined upstream pressure thereto. Normally closed supply valve means is connected along the diluent flow path between the diluent supply and the mixing means, and the normally closed supply valve means is operable to open selective actuation for permitting the diluent to flow through the flow path into the mixing means. Pumping means is operable upon selective energization to deliver a measured flow of the liquid concentrate from the source to the mixing means independently of the flow of the diluent. Nozzle means receives the mixed beverage from the mixing means and is operable to dispense the same to the atmosphere, In a specific embodiment of the invention, a flush valve is located within the module, the valve's inlet being connected to the diluent line between the diluent valve and the mixing chamber, and the valve's outlet being connected to deliver diluent to the line between the check valve and the pump.

~ 1 ~66675 ¦ BRIEF DESCRI PTION OF THE DRAWINGS
¦ A further understanding may be had by reference to the ¦ accompanying drawing in which:
¦ Figure 1 discloses a schematic of a dispenser using the module assembly of this lnvention: and ¦ Figure 2 shows a piston and sleeve valve useful as a ¦ flow control and pressure regulator.
., . I . ' '..
¦ ,DETAILED DESCRIPTION OF THE P}~EFERREr) EMBODIMENT
I As shown, a dispenser indicated generally at 10 is enclosed ¦ and supported by a housing (not shown), such housings being ¦ well known in the art. A dispensing module 12 shown by the ¦ dashed lines is installed in the dispenser 10. The concentrate . ¦ tank 14 is preferably positioned above the module 12 to allow ¦ gravity feed of juice concentxate into the module. The ; 15; ¦ concentrate tanX 14 is fitted with a check valve 16 which ¦ prevents the flow of juice concentrate from into the module's 8pace when there is no module in the dispenser.
The module has first connection means which activates check valve 16 allowing juice concentrate to flow out of the 1 concentrate tank. One example of suitable means lncludes prongs extending upward from said module and adapted to engage a ball I within check valve 16. When the module is placed in position, ¦ the prongs open the check valve. This allows concentrate to ¦ fluw freely into the connection means and into the module as 1 long as the module is in place. When the module is removed, the check valve 16 prevents leakage of the concentrate.
. . .
~: ^ 1066675 `
¦ A second check valve 18, located within the module 12, I retains the juice concentrate in the concentrate tank 14 until ¦ needed. When an actuating means, e.g., a lever, is depressed, ¦ an electric motor (not shown) connected to a pump 22 is activated ¦ The action of the pump 22 creates a negative pressure on the ¦ discharge side of the check valve 18, opening the valve and ¦ drawing juice concentrate into the pump. The pump 22 pulls ¦ juice concentrate through line 20 and pushes it through line ¦ 24 at a substantially uniform rate into the mixing chambers 26.
Diluent for the juice dispenser 10, e.g., water, is drawn from a suitable water supply 48, as for example, a city water supply line. The water is passed through a strainer 46 to remove entrained solid~,-such strainers being common in the --juice dispenser art. The water passes into cooling coils 44 where the water is cooled to the desired temperature. The technique for cooling water and juice concentrate is known in the art and forms no part of this invention. Water passes through a valve 42, as for example, a ball valve, which allows the water supply to be shut off when the module 12 i9 not in place.
The water supply is connected to the module 12 by any suitable connector means. One such means comprises a line between the valve 42 and a fitting with an O-ring 40 which engages a complimentary opening in the module. The fitting i8 securely held in place by a plate 41 which insures the fitting does not drop out of the module. The plate is fastened to the " . . ' .
. . .
. "- . . ~
. : ~
1~ 1066675 ` I
module housing by screws or other suitable fasteners. To disconnect the module, the fitting plate 41 can be removed and the O-ring seal disengaged.
In operation, with the water supply connected, water passes into the module and through a flow control 38. One example of a suitable flow control valve is a spring loaded pi~ton and 8 leeve vaIve as shown in Figure 2.
The valve configuration 50 shown has a piston 54 slidably mounted within a sleeve 52. The entire valve 50 would be mounted within a line or housing (not shown) in a manner well known in the dispenser art. Fluid enters the valve 50 and passes through an orifice 56. The orifice creates a pressure drop which reduces the pressure of the fluid flow. After passing through orifice 56, the fluid passes into the interior of the piston 54 and exits via aperatures 57, only one being ~hown. In general, there are four or more aperatures.
There i8 a continuous force on the face 55 of the piston 54 which tends to slide the piston axially within the sleeve 52.
If the force is great enough to slide the piston 54 over I aperatures 57, the flow of fluid will automatically stop. A
¦ mating sleeve 62 engages the end of the valve sleeve 52 near ¦ the aperature 57. An adjustable plunger 64 engages a ~ring 58 I which provides a force counterbalancing the force on face 55 ¦ of the piston 54. The plunger 64 can be used to vary the ¦ spring force so that the aperatures are fully uncovered. By I properly adju~ting the spring force, the desired amount of the -`'- 1 .
~ .
aperatures 57 can be opened to provide the proper flow of diluent for the desired juice. If there is a pressure surge, the -8pring force will be insufficient to absorb all the force on face 55 and a portion of the aperature will be covered which 5 automatically maintains the proper flow rate dispite an increased pressure.
The flow control will normally maintain a flow pressure of ; about S psi and insure that only the proper amount of water needed to provide the desired mixture is allowed to flow.
When the pump 22 is activated, the solenoid operated water supply valve 56 is simultaneously energized and water -allowed to flow from the water supply 48 through line 33 into , the mixing chamber 26. In the presently preferred practice of thi8 invention, lines 33 and 24 discharge tangentially into lS the mixing chamber 26, so that the flow of concentrate and water i8 tangentially with respect to the walls of the chamber, thereby creating vortex mixing. The mixture then f lows through . di8charge orifices located in the chamber and into the di8-; pen~ing nozzle 28.
20 ¦ If de8ired, the mixing chamber may be provided with any ¦ 8uitable aeration means to add air to the mixed juice, such ¦ aeration means being old in the art.
I When it i8 desired to clean the module 12, the module ¦ can be operated in a "flush" mode. In this mode, the solenoid ¦ operated flush valve 32 is electrically connected in parallel ¦ to the water 8upply solenoid valve 36. Energizing the drink : , I . ' .

dispensing ever causes valves 32 and 36 to be electrioally opened and permits water to flow through line 33 into the mixing chamber and upwards through lines 30 and 34 to the underside of the adapter check valve 18. The positive pressures created on check valve 18 by water from line 30 maintains valve 18 in a closed position, thereby preventing concentrate from entering the system. Low pressure water enters line 20, the pump 22 and line 24 for flushing juice concentrate from the pump, associated lines, and the mixing chambe~ 26.
Various modifications of this invention will become obvious to those skilled in the art. Although the preferred embodiment has been described hereinbefore, the invention i8 limLted OA by ~e rollowing clalma.
