A device for heating and emulsifying liquids, in particular drinks, which is unusually capable of generating a dense and creamy foam, comprises a steam-emitting member with which a hollow body can be associated. The steam-emitting member comprises a spout positioned along the hollow body at a height such as to be above the level of the liquid to be emulsified. Inserted coaxially inside the hollow body is a duct which defines a first passage and a second passage. A region for communication between the first passage, the second passage and a third passage for air, which is placed in communication with a groove formed in the inner surface of the hollow body, is provided between the steam-emitting member and the duct. The steam-emitting member comprises two annular projections provided with sectors which have different transverse dimensions and which are offset relative to one another and define a labyrinthine path.

1. A device for heating and emulsifying liquids, in particular drinks, comprising:a steam-emitting member and a hollow body which can be associated with the steam-emitting member, liquid and air being sucked into the inside of the hollow body and emulsified liquid being expelled from the inside of the hollow body, wherein the hollow body comprises means for defining two separate passages that communicate with one another and with the outside of the hollow body, the two passages including a first passage towards which the steam is directed, creating a region of partial vacuum inside the hollow body, and a second passage through which the liquid is sucked from outside the hollow body and is re-directed with the air towards the outside through the first passage;and a third passage for air is provided inside the hollow body, in which the two separate passages are coaxial with one another and the means for defining two separate passages comprise a duct inserted coaxially in the hollow body, the first passage being constituted by the channel inside the duct towards which the steam leaving a spout of the steam-emitting member is directed, and the second passage being constituted by a gap which is created between the hollow body and the duct,whereby the liquid which rises along the second passage and the air which descends from the third passage meet at a location of a region for communication between the first passage, the second passage and the third passage provided between the steam-emitting member and the duct, and, owing to the partial vacuum, are re-directed towards the outside through the first passage.2. A device according to claim 1, wherein the duct is inserted with interference in the hollow body.3. A device according to claim 2, wherein the duct comprises longitudinal ribs.4. A device according to claim 3, wherein the ribs comprise a step which is to abut an annular rib formed in the inner surface of the hollow body.5. A device according to claim 1, wherein the duct comprises teeth which are to be positioned beyond an annular tooth formed in the inner surface of the hollow body.6. A device according to claim 1, wherein one end of the duct comprises a lead-in portion.7. A device according to claim 1, wherein one end of the duct is “C”-shaped.8. A device according to claim 1, wherein the duct is connected to the steam-emitting member and comprises at least one opening for communication between the first passage and the second passage.9. A device according to claim 1, wherein the hollow body comprises at least one portion having a cross-section which decreases in the direction away from the steam-emitting member.10. A device according to claim 1, wherein a free surface of the hollow body has teeth.11. A device according to claim 1, wherein the inner surface of the hollow body comprises a groove for the entry of air, the third passage being placed in communication with that groove.12. A device according to claim 1, wherein the third passage comprises means for providing it with winding portions and/or for varying the passage cross-section thereof.13. A device according to claim 12, wherein the steam-emitting member comprises at least one annular projection provided with first sectors and second sectors, the first sectors having a transverse dimension relative to the member which is larger than the transverse dimension of the second sectors.14. A device according to claim 13, wherein the emitting member comprises at least two annular projections, the sectors of the one being offset relative to the sectors of the other.15. A device according to claim 1, wherein the third passage comprises a labyrinthine path.16. A device according to claim 1, wherein the steam-emitting member comprises a spout positioned along the hollow body at a height such as to be above the level of the liquid to be emulsified.17. A machine for the preparation of hot drinks, comprising at least one source of steam, comprising a device for heating and emulsifying liquids, according to claim 1, which can be associated with the source of steam.18. A device according to claim 1, wherein the duct is inserted coaxially in the hollow body downstream the steam-emitting member along the direction of the steam.19. A device according to claim 1, wherein the duct is inserted coaxially in the hollow body and an end of the duct projects slightly from the hollow body.20. A device according to claim 1, wherein the end of the duct which projects slightly from the hollow body is a “C”-shaped end.21. A device according to claim 1, wherein the two passages communicate with one another at the location of a lead-in portion of the duct.22. A device according to claim 1, wherein the two separate passages are substantially straight.
