A coffee maker for automatically preparing a coffee beverage, and optionally other beverages, having a housing, in which the grinder, brewing device, and boiler, for example, are accommodated, and an outlet unit, by way of which the desired beverage is dispensed. In the outlet unit, an outlet arrangement is provided, in which a plurality of tubular outlets are arranged side-by-side, and which are removably mounted in the outlet unit. On the front side of the housing, a display and operating unit can be arranged, by way of which the desired coffee beverage can be inputted, and by way of which information about the respective coffee beverage and/or the operational state of the machine are outputted. On the upper side of the housing, storage containers can be arranged, in which basic ingredients for the preparation of the coffee beverage, and other beverages as the case may be, are kept.

An output unit for a beverage dispenser outputs hot beverages and/or ingredients for beverages to a container standing below the output unit. The output unit has one or more outlet assemblies for beverages and/or ingredients. Improved cleaning and/or mixing is achieved in that each of the outlet assemblies has a central inner outlet and an outer outlet which concentrically encloses the inner outlet, and in that the outer outlet is designed as a ring nozzle directed in the outlet direction so that a fluid which is output through the outer outlet encloses the inner outlet in the form of a concentric liquid sheath.

A brewing device () for a coffee machine comprises a brewing cylinder () with a cylindrical hole and two pistons () by means of which the brewing cylinder () can be closed off in order to form a brewing chamber (). The brewing cylinder () and the pistons (and) are held in a frame (), in a way displaceable relative to one another, and are drivable via a drive device (). This drive device () comprises a spindle (), the two ends of which are designed as bearing pins (), and are mounted such that they are rotatable in a sliding way in bearing rings () fitted in the frame (). At least one supporting element () is inserted in at least one of the bearing rings (), and is pressible substantially radially against the bearing pin () by means of a spring element (). The bearing play between bearing ring () and bearing pin () is thereby compensated; a silent operation of the spindle in the brewing device results.

A brewing device () for a coffee machine comprises a brewing cylinder () with a cylindrical bore (), an upper piston () and a lower piston (), by means of which the brewing cylinder () is able to be closed off to form a brewing chamber (). The surface of the upper piston () and of the lower piston () facing the brewing chamber () is provided in each case with a sieve (), through which hot water is able to be conducted into the brewing chamber () or coffee is able to be discharged from the brewing chamber () in each case via a connecting channel () provided in the respective piston (). At least one of the sieves () is installed on a supporting structure () that is placeable on one of the pistons () and is lockable therewith. The respective supporting structure () is provided with a connecting element (), which is connectable in a sealed way to the connecting channel () of the respective piston (). By means of this arrangement the sieve can be easily taken out of the respective piston and put back in again.
