An assembly for creating milk froth and/or for heating milk is disclosed. It comprises a foaming device and optionally a milk container and a valve assembly. The foaming device is provided with a steam supply channel, an air supply channel, a milk supply channel and a discharge opening. In order to provide for an easy cleaning of the assembly and its microbicity, at least the components and/or cavities coming into contact with milk are provided with a hydrophobic and oleophobic surface consisting of nano-particles which consist partially of silver or a silver compounds.

What is claimed is: 1. An assembly for creating milk froth and/or for heating milk, comprising: a foaming device including a steam supply channel, an air supply channel, a milk supply channel, and a discharge opening; a nozzle between said steam supply channel and said milk supply channel whereby steam is discharged from said steam supply channel into said milk supply channel; and a mixing channel between said milk supply channel and said discharge opening, wherein at least said milk supply channel and said mixing channel are provided with a surface layer which is both hydrophobic and oleophobic, said surface layer including nano-particles of silver or a silver compound. 2. An assembly according to claim 1, in which said hydrophobic and oleophobic surface layer is provided by hydrophobic and oleophobic nano-particles, which nano-particles, including said nano-particles of silver or a silver compound, are worked-in into the surface of said nozzle, said milk supply channel, said discharge opening and said mixing channel. 3. An assembly according to claim 1, in which said hydrophobic and oleophobic surface layer is provided by hydrophobic and oleophobic nano-particles, which nano-particles, including said nano-particles of silver or a silver compound, are applied to the surface of said nozzle, said milk supply channel, said discharge opening and said mixing channel in the form of a coating. 4. An assembly according to claim 1, in which said hydrophobic and oleophobic surface layer is provided by hydrophobic and oleophobic nano-particles, which nano-particles, including said nano-particles of silver or a silver compound, show a chemical or physical bond with said surface. 5. An assembly according to claim 1, further comprising a milk container communicating with said milk supply channel. 6. An assembly according to claim 5, further comprising means for attaching said foaming device to said milk container. 7. An assembly according to claim 5, in which said foaming device comprises an appendage extending towards the bottom of said milk container, said milk supply channel being located in said appendage and having, at its distal end, an inlet opening communicating with said milk supply channel. 8. An assembly according to claim 7, in which said appendage forms part of said milk supply channel and is provided with said surface layer. 9. An assembly according to claim 1, in which said foaming device comprises a first cylindrical recess, communicating with said steam supply channel. 10. An assembly according to claim 9, in which said foaming device comprises a second cylindrical recess, communicating with said discharge opening. 11. An assembly according to claim 10, in which said foaming device comprises a coupling element provided with two cylindrical stub members, said stub members being adapted to be inserted into said first and second cylindrical recesses, one of said stub members being connectable to a steam supply hose and the other of said stub members being connectable to a discharge hose. 12. An assembly according to claim 1, in which said foaming device comprises a venting channel, opening into said milk supply channel and communicating with the ambient air, which can be closed by means of a valve member. 13. An assembly according to claim 1, wherein at least said nozzle is also provided with said surface layer. 14. An assembly according to claim 1, wherein at least said discharge opening is also provided with said surface layer.
