A beverages dispenser, particularly for carbonated beverages, comprises a cooled tank where beverage is stored, an inlet pipe to the tank, an inlet valve on the inlet pipe, a pump downstream the inlet valve for feeding a beverage to the tank in order to maintain a predetermined level wherein, an outlet pipe from the tank to a beverage dispensing nozzle, and an outlet valve on the outlet conduit. An auxiliary pipe is disposed between the inlet pipe downstream the inlet valve and the outlet pipe downstream the outlet valve and a control unit is adapted to close the inlet valve and to run the pump in order to empty the outlet pipe into the tank after the beverage is dispensed in order to prevent dripping.

1. A refrigerator appliance comprising a refrigeration compartment, a freezer compartment and a beverage dispenser comprising: at least a cooled tank where a beverage is stored,an inlet conduit to the tank,an inlet valve on the inlet conduit,a pump downstream the inlet valve for feeding the beverage
1. A refrigerator appliance comprising a refrigeration compartment, a freezer compartment and a beverage dispenser comprising: at least a cooled tank where a beverage is stored,an inlet conduit to the tank,an inlet valve on the inlet conduit,a pump downstream the inlet valve for feeding the beverage to the tank,an outlet conduit from the tank to a beverage dispensing nozzle,an outlet valve on the outlet conduit,an auxiliary conduit disposed between the inlet conduit downstream the inlet valve and the outlet conduit downstream the outlet valve; anda control unit adapted to close the inlet valve and to run the pump in order to empty the outlet conduit into the tank after the beverage is dispensed. 2. The refrigerator appliance according to claim 1, wherein the auxiliary conduit comprises a check valve preventing the flow of beverage from the inlet conduit to the outlet conduit. 3. The refrigerator appliance according to claim 1, wherein the tank is adapted to contain carbonated water and is provided with a conduit contained therein for feeding cooled water to the dispensing nozzle by means of a second outlet valve on an auxiliary outlet conduit connected to said outlet conduit. 4. The refrigerator appliance according to claim 3, wherein between the inlet conduit and the outlet conduit a by-pass conduit is installed for delivering still water from the tap to the dispensing nozzle. 5. The refrigerator appliance according to claim 1, wherein the beverage dispenser comprises a second outlet conduit connected to an auxiliary tank for hot water. 6. A method for dispensing beverages from a refrigerator beverage dispenser having at least a cooled tank where a beverage is stored, the method comprising: providing the beverage dispenser of claim 1;feeding the beverage to the tank through an inlet conduit and controlling such feeding by means of an inlet valve on the inlet conduit and a pump downstream the inlet valve in order to maintain a predetermined level in the tank;providing carbon dioxide to the tank to carbonate the beverage; anddispensing the beverage from the tank to a beverage dispensing nozzle through an outlet conduit provided with an outlet valve, wherein the inlet valve is closed and the pump is switched on after the beverage is dispensed and the outlet valve has been closed in order to suck the beverage from the outlet conduit downstream the outlet valve towards an auxiliary conduit disposed between the inlet conduit downstream the inlet valve and the outlet conduit downstream the outlet valve in order to empty the outlet conduit into the tank. 7. The method according to claim 6, wherein the auxiliary conduit comprises a check valve preventing the flow of beverage from the inlet conduit to the outlet conduit. 8. The method according to claim 6 wherein the tank is adapted to contain carbonated water. 9. A refrigerator appliance comprising a refrigeration compartment and a beverage dispenser configured to dispense carbonated beverages, comprising: at least a cooled tank where a beverage is stored,an inlet conduit to the tank,an inlet valve on the inlet conduit,a pump downstream the inlet valve for feeding the beverage to the tank,a carbon dioxide inlet conduit providing carbon dioxide to the tank to carbonate the beverage,an outlet conduit from the tank to a beverage dispensing nozzle,an outlet valve on the outlet conduit,an auxiliary conduit disposed between the inlet conduit downstream the inlet valve and the outlet conduit downstream the outlet valve; anda control unit adapted to close the inlet valve and to run the pump in order to empty the outlet conduit into the tank after the beverage is dispensed. 10. The refrigerator appliance of claim 9 wherein a cooling source for the cooled tank is cold air. 11. The refrigerator appliance of claim 9 wherein the control unit includes a button that a user may activate. 12. The refrigerator appliance of claim 9 wherein the control unit is further adapted to detect a low level of beverage in the tank, and in response to a low level detection, the control unit ensures that the pump is operating and opens the inlet valve. 13. The refrigerator appliance of claim 9 wherein the control unit is further adapted to detect a targeted level of beverage in the tank, and in response to the targeted level detection, the control unit closes the inlet valve. 14. The refrigerator appliance of claim 9 wherein the auxiliary conduit comprises a check valve preventing the flow of beverage from the inlet conduit to the outlet conduit. 15. The refrigerator appliance of claim 9 wherein the auxiliary conduit flows fluid into the tank to prevent the flow of beverage from the outlet conduit following dispensing of the beverage. 16. The refrigerator appliance of claim 9 where the beverage is water. 17. The refrigerator appliance of claim 9 further comprising a tap water conduit to deliver tap water to the beverage dispensing nozzle. 18. The refrigerator appliance of claim 9 further comprising a chilled water conduit to deliver chilled water to the beverage dispensing nozzle. 19. The refrigerator appliance of claim 9 further comprising a heated water conduit to deliver heated water to the beverage dispensing nozzle. 20. The refrigerator appliance of claim 9 with at least one additional dispensing nozzle connected to a conduit to deliver at least one of tap water, chilled water, and heated water.
