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

A device according to the invention for preparing frothed milk can be docked on a beverage preparation machine (101) and for this purpose has at least one connection for steam generated by the beverage preparation machine and an interface for electrical current delivered by the beverage preparation machine. The device additionally has a milk foaming unit comprising a gear pump (7). The gear pump is connected on the input side to a milk supply line and to an air supply. A milk nozzle is additionally present on a path of the milk conveyed by the gear pump, and the milk, the steam and air can be supplied to this milk nozzle.

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...
