Embodiment Construction

[0035] FIG. 1 shows an exemplary embodiment of a device 15 according to the invention, which has a separate fixing element 16 and a disposable part 26 underneath a steam supply line 1 with a steam nozzle 2 . FIG. 2 shows a section through the two tubes 55A, 55B of the multiple tube section 54 for the structure according to FIG. 1 , which is shown in detail in FIG. 3 . The milk suction tube 35 is immersed in the milk container 6 which is partially filled with milk 7 to be pumped. The milk froth flow 14 leaving the device 15 through the outlet opening 32 reaches a separate milk froth container 8 which is partially filled with frothed milk 9 .

[0036] The fastening part 16 is preferably made of elastic plastic so that it can be easily connected to the steam nozzle 2 of the steam supply line 1 . For this purpose, the body of the steam nozzle 2 is equipped with a snap ring 4 on which the snap groove 17 of the fixing part 16 snaps. A simple and quick connectable connection betwee...

Abstract

The invention relates to a device (15) for foaming milk by means of external suction equipment (35), used as an accessory for espresso machines or similar domestic appliances. Said device comprises a fixed part that can be connected to the steam supply conduit (1) of said machines and an easily interchangeable disposable part (26) containing all parts that come into contact with the milk. The invention is characterised in that components of the disposable parts and in some embodiments of the invention even the entire disposable part consist(s) of thin-walled plastic tubes of the drinking straw type, which can be produced in a cost-effective and environmentally friendly manner by extrusion and subsequent thermoplastic forming. The use of the inventive device obviates the need for the inconvenient cleaning of conventional foaming nozzles and eliminates hygiene problems.

Description

technical field [0001] The invention relates to a device for frothing milk according to the preamble of claim 1 , which has an external milk suction device. Background technique [0002] Such a device is known as an add-on device for connection to a steam inlet pipe provided with a steam nozzle of an espresso machine or similar domestic machine, wherein the device is equipped with a A nozzle arrangement generating a low pressure in the low-pressure chamber and having separately or jointly guided suction lines for milk and air or a milk-air mixture connected to the low-pressure chamber and for outputting the steam-milk produced - an outlet for the air mixture, the milk suction duct can be immersed in the milk to be treated in a container arranged for containing the steam-milk-air mixture or in a separate / separate container. [0003] European patent document EP 1 115 317 A1 describes a device in which untreated milk pumped through an external milk feed line, preferably from a...
