Abstract

The present invention provides a carbonated and non-carbonated water supplier for a beverage dispensing apparatus for a residential refrigerator. The beverage dispensing apparatus includes a drink supplier including a drink supply canister holder for holding a plurality of drink supply canisters, a plurality of valve actuators for causing the drink supply to be selectively released from the drink supply canisters, the water supplier for selectively supplying carbonated water and non-carbonated water for producing the beverages, a gas supplier for supplying CO₂ gas to carbonate the carbonated water provided by the water supplier and for supplying CO₂ gas or other gas for pressurizing the drink supply canisters to provide a consistent flow rate of the drink supply from the drink supply canisters and one or more beverage requesters for enabling users to request one of a plurality of beverages.

Claims

1. A beverage dispensing apparatus for a refrigerator, said beverage dispensing apparatus comprising:

a drink supply canister holder mounted in said refrigerator and adapted to hold a drink supply canister having a drink supply outlet valve from which is discharged, a drink supply;

a water supplier mounted in the refrigerator, said water supplier including a carbonated water line, a non-carbonated water line, a carbonated water valve connected to the carbonated water line, a non-carbonated water valve connected to the non-carbonated water line, and a water dispenser connected to the carbonated water valve and the non-carbonated water valve, said water dispenser including a water tube positioned adjacent to the drink supply outlet valve, the water tube having at least one wall which;

(a) defines a carbonated water inlet;

(b) defines a non-carbonated water inlet;

(c) defines a channel in fluid communication with both the carbonated water inlet and the non-carbonated water inlet;

(d) is shaped so as to define a central aperture; and

(e) defines a plurality of orifices positioned about at least a portion of the central aperture, said drink supply outlet valve and said at least one wall being positioned on said apparatus so as to enable said drink supply to flow through said central aperture from above;

a gas supplier connected to said carbonated water line;

an actuator adapted to actuate the drink supply outlet valve; and

a controller adapted to operate said water supplier and actuator, the controller operable to cause;

(a) drink supply to flow from the drink supply outlet valve, through air and through the central aperture;

(b) carbonated water or non-carbonated water to flow from the orifices and through the central aperture so that said drink supply and said carbonated water or non-carbonated water simultaneously pass through the central aperture; and

(c) said drink supply and carbonated water or non-carbonated water to flow into a beverage collector.

2. The beverage dispensing apparatus of claim 1, wherein the water tube is at least partially cylindrical.

3. The beverage dispensing apparatus of claim 1, wherein the water tube is cylindrical.

4. The beverage dispensing apparatus of claim 1, wherein the water tube has a position at or below the drink supply outlet valve.

5. The beverage dispensing apparatus of claim 4, wherein the orifices are positioned in the water tube adjacent to different locations along a drink supply stream wall of the drink supply.

6. The beverage dispensing apparatus of claim 5, which includes a water injector connected to the wall of the water tube at each of the orifices.

7. The beverage dispensing apparatus of claim 6, wherein the water injectors have a predetermined angular orientation.

8. The beverage dispensing apparatus of claim 1, wherein the water supplier includes a carbonation tank connected to the carbonated water line and gas supplier.

9. The beverage dispensing apparatus of claim 1, wherein the water supplier includes a water filter connected to the carbonated water line and the non-carbonated water line.

10. The beverage dispensing apparatus of claim 1, wherein the water supplier includes a cold plate connected to the carbonated water line for chilling water before the water is carbonated.

11. The beverage dispensing apparatus of claim 1, wherein the water supplier includes a cold plate connected to the carbonated water line for chilling water before and after the water is carbonated.
