Embodiment Construction

[0032] It should be noted that structural and / or functional elements common to different variants in these figures may have the same reference numerals.

[0033] Machines for preparing hot beverages according to the invention are, for example but not exclusively, "espresso-type" coffee machines, such as figure 1 Shown includes a frame 1 containing a steam source 2, such as an electric boiler, which is connected to figure 1 A high pressure pump not shown is connected to the water container. The steam source 2 is connected to a drainage tube 3 which extends outside the frame 1 and whose end is equipped with a connection element 4 of a device 10 for heating and emulsifying the liquid. According to an example, the device 10 is mounted on the connection element 4 in a detachable manner.

[0034] Once mounted on this connecting element 4, the device 10 serves to ensure the injection of steam mixed with air into the liquid to be heated and emulsified. Thus, within the context of t...

Abstract

The invention relates to a device for reheating and emulsifying a liquid. The device has an elongated body that includes a connection head and an internal channel for supplying vapor, where the channel connects the connection head to an ejector nozzle. A rigid, removable, tubular outer sleeve surrounds a tubular core. A suction pipe is defined by the sleeve in cooperation with a longitudinal recess. A sealing unit is provided between the sleeve and the nozzle that are made of a separate flexible material that is distinct from sleeve material for assembling / disassembling of the sleeve.

Description

technical field [0001] The invention relates to the technical field of emulsifying and heating liquids such as milk by means of steam in order to obtain, for example, hot milk froth for preparing coffee-based beverages. In a preferred application, the invention relates to a steam nozzle for a machine for preparing hot beverages, such as a "espresso-type" coffee machine. Background technique [0002] Devices for heating and emulsifying liquids are known which comprise a tubular elongated body comprising a head for connection to a steam source. The device comprises a metal tube placed inside an elongated body and held within the body by diffuser feet screwed onto the body. The inside of the tube defines an internal steam supply channel connecting the connection head with the injector of the air / steam mixing nozzle with Venturi effect, which nozzle is located in the diffuser foot. The outer wall of the tube, together with the tubular body, defines an air intake annular duct w...
