Embodiment Construction

[0061] Machine 1 (milk frother) for preparing frothed milk as a whole figure 1 shown. figure 2 An exploded view of its part is shown. The machine 1 has a milk container 3 , a milk frothing unit 5 and a lid 6 .

[0062] In the embodiment shown, the milk container 3 has a double-walled design for thermal insulation, but a single-walled design is also possible. It can be transparent or have a window to check the milk level.

[0063] The milk container 3 and the lid 6 can be coordinated with each other in such a way that the lid 6 can also be placed directly on the milk container 3 without the milk foaming unit 5 being arranged in between, whereby the filled milk container with the lid can be placed, for example, in a refrigerator . The milk container and lid can also be cleaned in a simple manner and are designed, for example, to be washable in a washing machine.

[0064] The elements of the milk frother unit 5 are in the image 3 is shown in an exploded view. An electric...

Abstract

The invention relates to a milk frother, wherein a milk frother for preparing frothed milk according to the invention can be docked to a beverage preparation machine (101) and has for this purpose at least one device for the water produced by the beverage preparation machine A port for steam and an interface for the electrical current delivered by the beverage preparation machine. The machine also has a milk frothing unit comprising a gear pump (7). The gear pump is connected on the inlet side to the milk supply line and the air supply. Also provided on the path of the milk delivered by the gear pump is a mixing nozzle, to which milk, water vapor and air can be supplied.

Description

technical field [0001] The invention relates to the field of beverage preparation machines. In particular it relates to a machine for making milk froth and milk drinks which can be docked to a beverage preparation machine, and a beverage preparation system with such a machine. Background technique [0002] Milk frothers are known either as an integral module of a coffee machine or as a separate machine dockable to the coffee machine. EP2047779 shows a coffee machine with a dockable milk module, where hot steam from the coffee machine is used to froth the milk drawn from the milk module container according to the Venturi principle. [0003] The previously described solution based on the Venturi principle can only prepare hot milk froth. However, it is often also desirable to prepare cold milk foam. For example EP2326224 shows a milk frother with a gear pump as the central frothing element. On the inlet side of the gear pump, air and milk are sucked in, the milk is frothed...
