Dual chamber carbonator for dispensing drinks
First Claim
1. Water carbonation apparatus for dispensing carbonated drinks, comprising at least two independent carbonation chambers, gas supply means for supplying carbonation gas to a selected one of said at least two carbonation chambers in which a quantity of water is to be carbonated so as to provide said carbonated water therein, carbonation selector means for selectively coupling said gas supply means to said selected one of said at least two carbonation chambers, and chamber selector means for dispensing said carbonated water from said selected one of said at least two carbonation chambers, each of said at least two carbonation chambers defining a volume substantially corresponding to a single drink.

Abstract
Water carbonation apparatus for dispensing flavored carbonated drinks supplies carbonation gas to at least two carbonation chambers in each of which water is carbonated and thereafter dispensed to provide a drink. The apparatus has a carbonation selector valve for determining a sequence in which carbonation gas is supplied from the gas supply to each carbonation chamber, and a chamber selector valve for controlling the dispensing of carbonated water from the carbonation chambers in accordance with the desired sequence. The sequence of operations is controlled by a control circuit so that the sequencing of gas supply to and evacuation from the chambers is controlled in conjunction with the operation of the chamber selector valve.

8. Apparatus for selectively dispensing carbonated water from water carbonation apparatus having a plurality of carbonation chambers, each of said carbonation chambers having a displaceably actuated chamber valve means associated therewith for dispensing said carbonated water therefrom, said apparatus comprising an elevating member displaceable towards said carbonation chambers, a tilt member pivotally mounted upon said elevating member and rockable into a plurality of positions, whereby in each of said plurality of positions said tilt means selectively actuates a corresponding one of said chamber valve means to dispense carbonated water therefrom.

9. Carbonated drink dispensing apparatus comprising first and second carbonation chambers, supply means for supplying water and gas to said first and second carbonation chambers for the formation of carbonated water therein, first and second carbonated water dispensing valves associated with each of said first and second carbonation chambers and openable against the action of pressure therewithin, and valve actuating means connected to each of said first and second carbonated water dispensing valves, said valve actuating means being operable so that when there is a pressure difference between one of said first and second carbonation chambers and the dispensing valve associated with said one of said first and second carbonation chambers which is at a lower pressure, said carbonation chamber is opened while said dispensing valve associated with the other of said first and second carbonation chambers which is at a higher pressure remains closed.
- 10. Water carbonation apparatus for dispensing carbonated drinks comprising at least two carbonation chambers, gas supply means for supplying carbonation gas to a selected one of said at least two carbonation chambers in which a quantity of water is to be carbonated, carbonation selector means for selectively coupling said gas supply means to a selected one of said at least two carbonation chambers, chamber selector means for dispensing carbonated water from said selected one of said at least two carbonation chambers, said chamber selector means comprising at least two valve means communicating with said respective carbonation chambers for selectively allowing the passage of said carbonated water from said carbonation chambers, and pressure actuated valve opening means for selectively opening one of said at least two valve means, said valve opening means being responsive to the pressures within said at least two carbonation chambers to select a respective one of said at least two valve means to be opened.
-
13. A method of operating apparatus for dispensing carbonated drinks comprising at least two carbonation chambers, said method comprising supplying water to said at least two carbonation chambers, supplying carbonation gas to one of said at least two carbonation chambers to effect carbonation therein, rerouting said carbonation gas to the other of said at least two carbonation chambers, exhausting residual carbonation gas from said one of said at least two carbonation chambers, so as to ensure that the gas pressure in said one of said at least two carbonation chambers is reduced to a level substantially corresponding to atmospheric pressure, and dispensing a drink from said one of said at least two carbonation chambers.
-
14. A method of dispensing a carbonated drink from apparatus including at least two carbonation chambers, said method comprising supplying water to one of said at least two carbonation chambers, supplying carbonation gas to said one of said at least two carbonation chambers so as to effect carbonation therein, dispensing a carbonated drink from said one of said at least two carbonation chambers, supplying water to the other of said at least two carbonation chambers before said dispensing of said drink from said one of said at least two carbonation chambers, supplying carbonation gas to said other of said at least two carbonation chambers, and dispensing a drink from said other of said at least two carbonation chambers.
-
15. A method of dispensing a carbonated drink from apparatus comprising at least two carbonation chambers comprising supplying water to one of said at least two carbonation chambers, supplying carbonation gas to said one of said at least two carbonation chambers so as to effect carbonation therein, and dispensing said carbonated drink from said one of said at least two carbonation chambers, supplying water to said other of said at least two carbonation chambers, supplying carbonation gas to said other of said at least two carbonation chambers for effecting carbonation therein, and dispensing a drink from said other of said at least two carbonation chambers, and detecting a signal indicating that a drink is required thereby causing said supply of said water to said one of said at least two carbonation chambers and said dispensing of said water from said other of said at least two carbonation chambers.
- 16. A method of operating carbonated drink dispensing apparatus comprising at least two carbonation chambers, said method comprising performing an operating cycle which includes supplying water to one of said at least two carbonation chambers, supplying carbonation gas to said one of said at least two carbonation chambers for effecting carbonation therein, and supplying water to the other of said at least two carbonation chambers.
