Spout for a beverage maker

The invention relates to a spout of a beverage maker, especially with direct drainage of the drink into a cup, e.g. B. on an espresso machine.

With such outlets, from which the liquid is preferred falls under the action of gravity down into a collecting vessel, there is the problem that the one leaves the outlet Beam dances, i.e. is accelerated to the side in alternating directions. Sometimes there are also individual drops torn from the jet and sprayed into the environment.

The invention is based on the object of creating a beverage maker of the type described at the outset, in which the dancing of the running jet and especially a spraying of the drink is safely avoided.

This object is achieved according to the invention in that the lower end section of the outlet has a flow cross section has between about 7 and 20 sqmm, preferably "the flow cross-section of the end section is about 13 sqmm an approximately circular flow cross-section of the end section, this corresponds to diameters between 3 and 5 mm and in particular about 4 now. This design has the advantage that even individual ones fed to the end section of the outlet Drops touch the inner wall on all sides and thus any preference for one direction when removing the liquid from the Leakage is avoided. Since the jet no longer dances, the loosening of individual drops is largely or completely avoided.

Appropriately, the lower end section of the outlet represents a narrowing of the outlet, the length of which is at least about 4 to 8 mm and preferably 5 to 6 mm. Through this it is avoided that an oblique in the narrowed Endab-.

cut incoming jet or drop also at its discharge end still has a lateral impulse and leads to a deflection of the dispensed liquid to the side.

In the following, an exemplary embodiment of the invention is based on a, schematic drawing explained in more detail, which is a vertical section through an espresso machine with a centrifugal filter shows.

The espresso machine shown in the figures has a base housing 2 on which a ring-shaped Sivnraelkanal Ί is arranged, which has support arms on its underside, which carry an electric motor in the form of a vertically upwardly projecting output shaft 10 from triebswelIe 10 a on the Saminelkanal k plugged lid terminates in a Kupplungsseheibe 12 on which a centrifugal filter is plugged 14th has the centrifugal Ik surrounding a small distance vertical annular wall 18 which k protrudes downwards into the collecting channel and along which the centrifuged coffee downward flows. the cover 16 has a central deck side Einguilöffnung 20 for the brewing water on, under which the lid of the centrifugal filter lh a pouring-in opening is on this. the annular collecting channel h has an inclined bottom 2k at the deepest from its place, a tubular Drain channel 26 protrudes approximately radially outward with a slight gradient.

The tubular drainage channel 26 has at a distance from

ve-rfflwues Housing 2 with a downwardly angled / downpipe 30 a relatively wide upper tube section 32, an adjoining conical Yerjüngungsabschnitt 34 and a adjoining lower end section 36, under which a coffee cup 38 can be placed. The narrow end of the Downpipe 30 has a circular cross-section with an inner diameter of 4 mm and a length of 6 mm.

That the outlet 26 has only a narrowed, relatively short end section 36 has and is not kept so tight over a larger part of its length, has the advantage that it has a smaller Has drainage resistance and the relatively short narrowing is easier to remove from impurities such as lime deposits is to be cleaned.
