Definitions

  • the amount of carbonation of the withdrawing liquid can vary. Additionally,-it may be desirable to add a further carbonation to the system during dispensing to provide a back pressure to force the soda from the mixing chamber.
  • the prior art carbonation devices while using additional gas flow to the pressure vessel to aid in dispensing soda, have not utilized this gas flow to aid in the carbonation of the dispensed fluid.
  • the present invention overcomes the deficiencies in the prior art by providing a fluid carbonator which introduces fluid to the pressure chamber ata normal line pressure and, by appropriate direction of the entering gas stream, adds gas to the pressure chamber during dispensing in such a manner that the added gas supercharges the soda water, hereinafter referred to as soda, fluid or carbonated fluid, being dispensed.
  • the pressure mixing chamber is provided with a valveoperated vent adapted to vent the interior of the pressure chamber to the atmosphere.
  • This vent is open during the filling operation, thereby allowing the pressure chamber to be filled with fluid from a low pressure line such as a standard water tap.
  • the pressurized gas supply system is closed.
  • the vent is closed and the pressurized gas supply system is opened, thereby allowing the chamber to be pressurized with C
  • the presence of high-pressure CO in the pressure chamber causes a baclrflow of pressure into the fluid supply system actuating a checlt valve to cutoff fluid flow.
  • An adjustable pressure regulator may be attached to the vent to allow the vent system to selectively retain a desired pressure in the pressure chamber during refilling. This is particularly advantageous in situations where the pressure chamber is attached to a high pressure fluid source. In such situations the adjustable pressure regulator can be set to a pressure slightly below the fluid line pressure but above atmospheric pressure. This provides a saving in CO inasmuch as the pressure chamber is not entirely evacuated during refilling with fluid. In those situations where a low fluid line pressure is encountered, the adjustable pressure regulator attached to the vent system can be set to a lower pressure retention figure or even to atmospheric pressure.
  • the present invention thereby provides a liquid carbonator which can operate from a low-pressure level fluid source without the need of pumps or other fluid flow enhancers and which supercharges the carbonation of the liquid during dispensing from the mixing chamber.
  • FIG. 1 is a schematic view in cross section illustrating the carbonator of this invention.
  • FIG. 2 is a cross-sectional view taken along the lines II-Il of FIG. ll.
  • FIG. 3 is a schematic diagram of an electrical circuit for the carbonator of this invention illustrating the initial position in the operating sequence.
  • FIG. t is a view similar to FIG. 3 illustrating the second position in the operating sequence thereof.
  • FIG. 5 is a view similar to FIGS. 3 and 4 illustrating the third position in the operating sequence thereof.
  • FIG. 6 is a view similar to FIGS. 3, 4 and 5 illustrating the fourth position in the operating sequence thereof.
  • the carbonator 10 of this invention includes a pressure mixing chamber ll! which is illustrated as being oval but which may be of other configurations.
  • the mixing chamber 11 has a conduit 12 communicating therewith on one end and communicating with a check valve 13 on the other end.
  • the check valve 13 is operatively connected to a conduit 14 adapted to be connected-to a fluid supply source, such as a standard water tap line, associated with a fluid at a positive pressure.
  • the check valve 13 is of the type designed to allow fluid flow in one direction only, in this instance into the mixing chamber 11. When the pressure in the mixing chamber it is greater than the positive pressure of the fluid in the conduit it, thereby tending to force fluid back through the conduit. The check valve 13 will block such fluid flow.
  • vent pipe 15 projects through a wall 16 of the mixing chamber llll and terminates near the top thereof.
  • vent pipe is illustrated as being a simple conduit, it is to be understood that it may take other configurations such as a simple valve opening in the mixing chamber 11.
  • the vent pipe 15 communicates with a conduit 17 in which is associated in pressure release valve 18 adapted to open if the pressure in the mixing chamber 11 exceeds a safe level.
  • the vent pipe 15 also has associated therewith a normally closed valve 19 which is illustrated as being operated by a solenoid 20.
  • An adjustable pressure regulator 60 may be associated with the vent pipe 15 downstream from the valve 19. The adjustable pressure regulator 60 allows selective regulation of the amount of pressure retained in the pressure chamber during venting.
  • a gas supply system 21 is operatively connected to the mixing chamber 11 and comprises a conduit 22 which enters the wall 16 of the mixing chamber near the bottom of the chamber and direct the gas substantially tangential (i.e. more tangential than not) to a carbonated fluid discharge opening 51.
  • the conduit 22 is attached to a further conduit 23 through a normally open valve 24 which is illustrated as being operated by a solenoid 25.
  • the conduit 23 is operatively connected to a pressure regulator 26 which in turn is operatively connected to a further conduit 27 adapted to be connected to a source of pressurized C0
  • the pressure regulator 26 is adapted to provide a constant pressure to the mixing chamber 11, as for example 100 lb. per sq. in., even though the pressure in the conduit 27 may be considerably above that.
  • a dispensing system 28 is associated with the mixing chamber 11 and is illustrated as comprising a conduit 29 one end portion of which is connected to the discharge opening 51, the other end portion extends through the wall 16 of the mixing chamber at the bottom thereof and terminates in a valve 39 operated by a dispensing handle 31.
  • a mixing head 32 having a dispensing opening 33 therein is operatively connected to the valve 30.
  • the syrup supply system can also be infed to the dispensing valve 30 and mixed with the soda in the mixing head 32.
  • a normally closed switch 34 having electrical wires 35 attached thereto.
  • the switch is adapted to be operated by the dispensing handle 31 coextensively with the valve 30.
  • the switch 34 can be considered as being a first control system.
  • a second control system 36 is positioned within the mixing chamber 11 and is adapted to sense the fluid level therein.
  • the second control system is illustrated as comprising a central column 37 extending from the bottom of the mixing chamber 11 to near the top thereof.
  • a buoyant float 38 is positioned around the column 37 and adapted to move up and down thereon.
  • Near the top of the column 37 interior thereof is a reed switch 39.
  • the reed switch 39 is of a type normally closed in its free state.
  • a magnet associated with the float 38 is adapted to open the switch 39 when the float rises to a certain point on the column 37. Opening of the switch 39 breaks the contact between the electrical wires 40 and 41.
  • FIGS. 3 through 6 schematically illustrate a simplified wiring diagram for the carbonator 10.
  • the system comprises two switches 34 and 39 and the two solenoid valve operators and with the switches in series and the valve operators in parallel.
  • the switches 34 and 39 are normally closed while the valve 24 on the gas inlet 22 operated by the solenoid 25 is normally open.
  • FIG. 3 illustrates the system as it is pictured in FIG. 1 with the mixing chamber 11 filled with fluid to its desired operating height.
  • the switch 34 is closed while the switch 39, due to the presence of the magnet carried by the float 38, is held open. Therefore the solenoids 20 and 25 are not energized by the power source to which the ends 45 and 46 of the wires 47, 48 are coupled.
  • the solenoids 20 and 25 are parallelly connected between the wires 47 and 48.
  • valve 19 on the vent pipe I5 is closed while the valve 24 on the gas supply system 2l is open. Therefore pressurized CO is free to pass into the mixing chamber 11 where some of it will be dissolved in the fluid in the chamber while the remainder rises to the upper portion 52 of the chamber pressurizing the chamber to whatever pressure level the pressure regulator 26 is set.
  • the presence of pressure in the chamber 11 greater than the line pressure in the conduit 14 attached to the fluid supply system produces a back pressure in the conduit 12 effective to actuate the check valve 13 thereby preventing flow of fluid into the mixing chamber I].
  • the handle 31 on the dispensing valve 30 is actuated to open the valve thereby passing soda through the conduit 29 to the mixing head 32 where it may be mixed with flavored syrup or the like.
  • Actuating the valve 30 opens the switch 34 associated therewith producing the electrical configuration shown in FIG. 4.
  • the valve 19 is still closed, the valve 24 is open and the valve 30 is open.
  • Both the switches 34 and 39 are open, thereby preventing cnergization of the solenoids 20 and 25. Fluid from the mixing chamber will then be forced out of the chamber due to the presence of high pressure therein.
  • the pressure therein will drop, destroying the pressure equalization in the gas supply system and allowing further gas to enter the chamber 11 in an attempt to continue to pressurize it at the pressure set by the pressure regulator 26.
  • the entering gas from the conduit 22 acts, in a manner hereinafter described, to supercharge the exiting fluid and to continue the pressure in the mixing chamber at the desired level.
  • the solenoid 20 will be deenergized and the valve 19 will be returned to its normally closed position by means such as springs or the like. This will stop venting of the chamber to the atmosphere.
  • deenergiration of the solenoid 25 will allow the valve 24 to return to its normally open position and a flow of gas will begin from the gas supply system through the conduit 22 to the interior of the mixing chamber. This flow is caused by the difference in pressure between the interior of the mixing chamber and the gas supply system downstream of the pressure regulator 26.
  • an adjustable pressure regulator fill is provided in thevent system.
  • the adjustable pressure regulator 60 allows a selected pressure to be retained in the pressure chamber during venting of the chamber. Therefore in situations where the fluid pressure in the conduit M is relatively high, the adjustable pressure regulator 60 can be set at a level below that pressure but above atmospheric pressure thereby retaining a pressure in the pressure vessel even though the valve 19 is open. Such a pressure will not hinder flow of fluid to the pressure chamber in as much as the fluid line pressure still remains greater than the pressure interior of the pressure chamber.
  • the present invention contemplates the use of a supercharging capacity utilizing the gas flow from the gas supply system 21 during dispensing.
  • an indentation or ledge 50 is formed in the wall to of the pressure vessel lli near the bottom thereof and adjacent the opening 51 from which the dispensing conduit 29 extends.
  • the conduit 22 tenninates at a backwall 53 of the ledge 5d and projects the gas stream into the interior of the pressure vessel 11 through an aperture in the wall 53.
  • the conduit 22 is so located with respect to the opening 51 that the gas stream entering the mixing chamber ii is directed substantially tangential (i.e. more tangential than not) relative to the opening 51.
  • the entering gas stream is described as being directed tangentially to the opening 511 in order to minimize turbulence, it is to be understood that the gas stream could be passed directly over or chordally to the opening or at some other relative direction thereto. It is also to be understood that a nozzle may be placed on the end of the conduit 22 interior of the mixing chamber 11 to further. aid in the direction of the gas stream and to enhance the second stage carbonation of the dispensing fluid.
  • a carbonator for carbonating fluids in a mixing chamber having liquid and gas inlets to the chamber and a dispensing outlet adapted to pass carbonated fluid from the chamber, the improvement of: continuing the gas flow under pressure into the chamber during dispensing of fluid from the chamber and directing the entering gas stream past the dispensing outlet to increase the carbonation level of the fluid being dispensed, the gas inlet conduit terminating in relatively close spaced relation to the outlet opening and the pressured gas stream from said conduit being directed with regard to the outlet such that the fluid stream to the outlet partially intersects the gas stream.
  • a carbonator for carbonating fluids comprising: a pressure vessel mixing chamber, a vent connected to said chamber adapted to vent the interior thereof to the atmosphere, at fluid source connected with said mixing chamber adapted to supply fluid thereto, a relatively high pressure gas source connected to said mixing chamber and adapted to supply pressurized gas thereto, a dispensing opening in said chamber adapted to withdraw fluid from the interior thereof, means for closing the vent, means for shutting off flow of fluid to the mixing chamber, means for shutting otf flow of pressurized gas to the mixing chamber, means for stopping withdrawal of fluid from the mixing chamber, means for controlling the vent means and gas means, and means for adding carbonation to fluid being withdrawn from the chamber throughout said dispensing opening, the inlet conduit from the gas source terminating in relatively close spaced relation to the dispensing opening, the gas stream from the conduit being directed at the dispensing opening such that thc fluid stream from the chamber through the dispensing opening partially intersects the relatively high pressure gas stream from the conduit.
