- an effective cleaning of the feed line can be made possible.
- only a hot water and / or steam outlet must be provided if it is not present anyway (which is the case with most coffee machines), and the user only has to remove and remove the inlet end of the supply line from and to the milk storage container connect the outlet to perform a cleaning process.
- the outlet is preferably arranged in the region of the storage container.
- connection device may include a specially adapted coupling piece.
- the supply line can be mounted either in or on the reservoir.
- a particularly preferred and easy-to-clean design is that the supply line to the reservoir, and that is attached to a fixed integrated into the reservoir suction. In this way, the intake manifold can be cleaned together with the reservoir in a simple manner, for example in a dishwasher, while an internal cleaning of the supply hose takes place in the manner according to the invention.
- Fig. 3 shows a third principle of the invention in a schematic representation
- Fig. 4 shows a coffee machine according to the invention in a schematic representation.
- the device 1 shows a first embodiment of a device 1 according to the invention for feeding milk from a storage container 2 to an output device 3.
- the device 1 shown only as a schematic diagram can be part of any device that handles milk in the manner described.
- the device 1 is designed as a device for preparing and dispensing heated milk froth and contains for this purpose a foaming device 4, which may be formed in a known manner, for example, the frothing device according to DE 44 45 436 may contain.
- the mode of action and the structural design of foaming devices are known and need not be explained again.
- the frothing device 4 is connected via a supply line 5 to the reservoir 2 for the milk in combination.
- the supply line 5 is detachably attached with its inlet end 5a in or on the storage container 2, in the illustrated embodiment simply inserted into the storage container 2.
- the outlet end 5b of the supply line 5 is fixed to the frothing device 4, but may also be detachably arranged there to allow disassembly for basic cleaning.
- the supply line 5 is preferably flexible, and in particular a flexible hose made of plastic or rubber.
- the foaming device 4 is supplied in the illustrated embodiment via a line 6 air, which is either sucked by the Venturi principle or provided as compressed air, for example via a compressed air source 7, such as a compressed air cartridge or a pump or the like.
- the frothing device 4 is supplied with steam for heating the milk via a further line 8.
- the line 8 is connected to a suitable steam generator 9.
- the steam generator 9 is of conventional design and may be formed, for example, as a water heater. Preferably, however, a combined hot water and steam generator is used, which supplies 4 hot water for a hot water outlet 10 in addition to the steam for the AufM ⁇ gifted.
- the hot water outlet 10, through which also vapor portions can be discharged, is accessible to the user and arranged so that it lies in the region of the inlet end 5a of the supply line 5 when the supply line 5 is connected to the frothing device 4.
- the hot water outlet 10 should be located at a distance from the outlet end 5b of the supply line 5, which is equal to or smaller than the total length of the supply line 5 between the inlet and outlet ends 5a, 5b.
- the hot water outlet 10 is arranged in the region of the reservoir 2 for the milk.
- connection device 11 includes a coupling piece 12 which is fixed to the hot water outlet 10.
