Patent ID: 11134807

Abstract:
Frothing device (40) for the use in a machine (100) for foaming and/or heating a fluid, comprising at least a first body (15) and a second body (16) assembled together to configure the frothing device (40); at least one of the first or second bodies (15, 16) comprising cavities to configure fluid conduits when the bodies (15, 16) are assembled together; the fluid conduits comprising a steam conduit (21) through which steam flows and heats the fluid; a fluid conduit (28) though which fluid flows by the under-pressure created when steam circulates through the steam conduit (28); and an air conduit (22) configured to be able to add air to the fluid conduit (28); the fluid conduits further comprising an expansion chamber (18) having an internal restriction in section allowing the fluid to be frothed when air has been added to the fluid conduit (28). The invention further refers to a machine (100) for foaming and/or heating a fluid by means of such a frothing device (40), comprising means for receiving and closing in a tight manner the two bodies (15, 16) configuring the frothing device (40) when the frothing device (40) is arranged in the machine (100) so that a closed fluid system using Venturi effect is created, these means for receiving and closing the two bodies (15, 16) preferably being also configured to refrigerate the frothing device (40) when arranged in the machine (100).
