The invention relates to a fluid or beverage dispensing device having self-cleaning dispensing nozzle. The device includes a body provided with a conduit having a first end to which a dispensing nozzle is connected, and a second end to which a fluid inlet line is intended to be connected. The device further includes a collector member that can move relative to the body between a first dispensing position in which the outlet of the nozzle is released from the collector member and a second cleaning position in which the collector member is placed in front of the nozzle outlet to collect any fluid that exits the outlet.

The dispensing device according to claim 1, wherein the collector member comprises a sleeve having an inner wall and in which the body and dispensing nozzle are guided and slide in an axial direction. 3. The dispensing device according to claim 2, wherein, in the cleaning position, the inner wall of the sleeve and the exterior surface of the body define the cleaning chamber and in that the dispensing nozzle outlet extends into the chamber so that both interior and exterior surfaces of the dispensing nozzle can be cleaned. 4. The dispensing device according to claim 3, wherein the cleaning chamber includes a drain orifice arranged in a lower wall of the sleeve. 5. The dispensing device according to claim 3, which further comprises two sealing gaskets arranged about the dispensing nozzle outlet. wherein, in the cleaning position, the chamber is sealed by the two sealing gaskets. 6. The dispensing device according to claim 2, wherein the dispensing nozzle includes an end portion provided with a collar which extends outside the sleeve whether the device is in the cleaning position or in the dispensing position. 7. The dispensing device according to claim 5, wherein one of the sealing gaskets is formed of a sealing joint arranged between a front surface of the sleeve and the collar. 8. The dispensing device according to claim 2, wherein the sleeve comprises a cylindrical portion extended by a converging truncated portion and the body comprises a first cylindrical section extended by a second section having a smaller diameter than the first section, with the second section extending at least partially into the truncated portion. 9. The dispensing device according to claim 8, wherein one of the sealing gaskets is formed of a sealing joint arranged between an inner wall of the cylindrical section of the sleeve and the exterior surface of the first section of the body. 10. The dispensing device according to claim 4, wherein the wall of the chamber arranged opposite the dispensing nozzle outlet is inclined towards the drain orifice. 11. The dispensing device according to claim 2, wherein the sleeve is mounted in fixation brackets which are secured to a base plate. 12. The dispensing device according to claim 11, wherein the body is connected to actuating means that are secured to the base plate, with the actuating means bringing the dispensing device respectively into the dispensing and cleaning positions in response to a control signal. 13. The dispensing device according to claim 1, wherein the conduit is inclined with respect to a horizontal line. 14. The dispensing device according to claim 13, wherein the dispensing nozzle includes a fluid dispensing cone, with the inclination of the conduit being such that the axis of the cone is substantially vertical. 15. A method for cleaning or rinsing a dispensing nozzle of a fluid dispensing device comprising: the dispensing nozzle; a body having an exterior surface and being provided with a conduit having a first end to which the dispensing nozzle is connected and a second end which can receive a fluid inlet line; a collector member which can move relative to the body between a first dispensing position in which the nozzle outlet is released from the collector member and a second cleaning position in which the collecting member forms with the body a cleaning chamber, with the nozzle being init ially in the dispensing position, the method comprising the steps of:placing the nozzle facing the collector member;flowing a cleaning or rinsing fluid through the conduit, nozzle, and in the cleaning chamber;collecting the cleaning or rinsing fluid that exits the nozzle in the collector member; andreplacing the nozzle back into the initial position. 16. The method according to claim 15, wherein the flowing step includes flowing the cleaning fluid through the conduit via pumping means. 17. A method for cleaning or rinsing a dispensing nozzle of a fluid dispensing device comprising: the dispensing nozzle; a body having an exterior surface and being provided with a conduit having a first end to which the dispensing nozzle is connected and a second end which can receive a fluid inlet line; a collector member which can move relative to the body between a first dispensing position in which the nozzle outlet is released from the collector member and a second cleaning position, with the nozzle being initially in the first dispensing position, the method comprising the steps of:placing the nozzle in the second cleaning position and facing the collector member;flowing a cleaning or rinsing fluid through the conduit and nozzle;collecting the cleaning or rinsing fluid that exits the nozzle in the collector member;replacing the nozzle back into the initial position; andcirculating the cleaning or rinsing fluid in a closed circuit. 18.
