Abstract:
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.
