The invention relates to a device (1) for preparing a beverage suitable for human consumption and having a fine-bubble foam layer. The device is provided with a beverage unit (2) for delivering the beverage under pressure and at least one nozzle (4) which is in fluid communication with the beverage unit for supplying the beverage to the nozzle such that the nozzle can generate a jet (12) of beverage. The device further comprises a receiving unit (14) into which the jet is directed for obtaining the beverage with the fine-bubble foam layer. The receiving unit is provided with a chamber (16) with at least one drain opening (18) for delivering the beverage with the fine-bubble foam layer and a jet impact member (20) accommodated in the chamber and having a top (22) that lies free from an inner wall (24) of the chamber. The nozzle and the jet impact member are mutually oriented such that-the jet hits against a portion of the top of the jet impact member, so that the jet after hitting against the jet impact member forms a mist of the beverage. The beverage with the fine-bubble foam layer subsequently leaves the drain opening. The device is constructed such that air (34) can only be supplied to the chamber through the at least one drain opening and/or through an air supply channel which extends through the jet impact member into the chamber.

The invention claimed is: 1. A device for preparing a beverage, comprising: a beverage unit supplying the beverage under pressure, a nozzle in fluid communication with the beverage unit such that the nozzle generates a jet of the beverage, and a receiving unit into which the jet is directed, the receiving unit comprising: a chamber having a drain opening and a channel extending to the nozzle, and a jet impact member disposed within the chamber and having a top which does not contact an inner wall of the chamber, wherein the nozzle and the jet impact member are mutually oriented such that the jet hits against at least a portion of the top of the jet impact member so that the beverage, after hitting against the jet impact member, leaves the chamber through the drain opening in the form of the beverage having a foam layer, wherein air can be supplied to the chamber exclusively through the drain opening. 2. A device as claimed in claim 1, wherein the chamber further comprises a product feed opening through which the jet enters the chamber. 3. A device as claimed in claim 2, wherein the product feed opening is formed by the nozzle. 4. A device as claimed in claim 3, wherein a space within the chamber between the nozzle and the jet impact member is unobstructed. 5. A device as claimed in claim 2, wherein the top of the jet impact member is disposed between the product feed opening and the drain opening. 6. A device as claimed in claim 2, wherein the top of the jet impact member is directed towards the product feed opening. 7. A device as claimed in claim 2, wherein a line that is perpendicular to a center of a surface of the top of the jet impact member is directed towards the product feed opening. 8. A device as claimed in claim 2, wherein a line that is perpendicular to a surface of the top of the jet impact member in a location where the jet hits the top of the jet impact member is directed towards the product feed opening. 9. A device as claimed in claim 1, wherein the top of the jet impact member is directed towards the nozzle. 10. A device as claimed in claim 1, wherein a line that is perpendicular to a surface of the top of the jet impact member in a location where the jet hits the top of the jet impact member is directed towards the nozzle. 11. A device as claimed in claim 1, wherein a line that is perpendicular to a surface of the top of the jet impact member in a location where the jet hits the top of the jet impact member is directed parallel to the jet. 12. A device as claimed in claim 1, wherein a surface of the top of the jet impact member is one of concave, convex, and planar. 13. A device as claimed in claim 1, wherein the top of the jet impact member is located in a center of the chamber, as viewed in a plane transverse to the jet. 14. A device as claimed in claim 1, wherein the top of the jet impact member is located on a central axis of the chamber. 15. A device as claimed in claim 1, wherein an axial direction of the jet impact member extends in a longitudinal direction of the chamber. 16. A device as claimed in claim 1, wherein the inner wall of the chamber is rotationally symmetrical in shape. 17. A device as claimed in claim 16, wherein the inner wall of the chamber is substantially rotationally symmetrical in shape about an axis of rotation which extends in a longitudinal direction of the chamber. 18. A device as claimed in claim 17, wherein the axis of rotation extends through the top of the jet impact member. 19. A device as claimed in claim 16, wherein the inner wall of the chamber is at least partially cylindrical in shape. 20. A device as claimed in claim 1, wherein the jet impact member is connected to the chamber by a lateral arm. 21. A device as claimed in claim 1, wherein the beverage unit further comprises: a holder containing a product to be one of extracted and dissolved; and a hot-water unit supplying hot water to the holder to produce the beverage. 22. A device as claimed in claim 21, wherein the chamber and the nozzle are connected to the holder. 23. A device as claimed in claim 22, wherein the jet impact member is connected to the holder. 24. A device as claimed in claim 22, wherein the jet impact member is not directly connected to the holder. 25. A device as claimed in claim 22, wherein the chamber and the nozzle are integrated with the holder. 26. A device as claimed in claim 23, wherein the jet impact member is integrated with the holder. 27. A device as claimed in claim 1, characterized in that the jet, after hitting the jet impact member, forms a mist of the beverage which flows against and/or along the inner wall of the chamber and subsequently leaves the chamber through the at least one drain opening in the form of the beverage with the ifne-bubble foam layer. 28. A device as claimed in claim 21, wherein the product is one of coffee, tea, and non-dairy creamer.
