Claim:
A device for heating and frothing a liquid comprising a container ( 1 ; 21 ), acting as a heating and frothing chamber, which is provided with an opening for the introduction of the liquid to be processed into said container ( 1 ; 21 ) and with a duct ( 3 ; 24 ) for introducing pressurised steam into the liquid contained in said container ( 1 ; 21 ), for heating the liquid and creating turbulence therein: wherein said duct has at least one steam outlet opening inclined downwards, so that steam flows out in a substantially radial and downward inclined direction; wherein said duct ( 3 ; 24 ) is fastened onto a bottom of said container ( 1 ; 21 ) so that an axis of said duct is parallel to an axis of said container ( 1 ; 21 ) and is equipped with a means for a sealed connection to a steam-supplying spout thus permitting steam from a steam supply to flow out from said at least one opening ( 5 ; 27 ), said at least one opening ( 5 ; 27 ) being provided as a set of openings ( 5 ; 27 ) adapted to be covered by the liquid when the liquid is poured into said container ( 1 ; 21 ) and steam introduction into the liquid thus creating conditions for frothing same; and wherein the sealed connection between said duct ( 3 ; 24 ) and the spout ( 11 ) is achieved through a jack ( 13 ), fitted into an upper end ( 15 ) of said duct ( 3 ; 24 ) with the interposition of an O-ring ( 17 ).
