Embodiment Construction

[0015] FIG. 1 shows a schematic longitudinal section through a brewing unit 1 for a coffee machine not shown in detail. The movable part of the brewing unit 1 is shown in its brewing position. In the exemplary embodiment shown, the brewing unit 1 has a housing 2 relative to which a brewing cartridge 3 and a moving piston 4 are displaceable in the direction of the longitudinal axis. In a manner not shown in detail, in the shown brewing unit 1 the brewing cartridge is driven in the direction of the longitudinal axis by a spindle drive. The moving piston 4 is driven by the brewing cylinder 3. As for the moving piston 4 , opposite to the brewing cylinder 3 , there is a static piston 5 which is connected to the housing 2 . Between the two pistons 4 and 5 is the brewing chamber 6 as part of the brewing cartridge 3 . The brewing chamber 6 is delimited by the piston bases of the two pistons 4 and 5 , depending on the amount of coffee to be filled into the brewing cartridge 3 . As ...

Abstract

The brewing unit (1) has a brewing chamber (6) containing the base coffee powder during the brewing process, hot water supplies (7, 9) provided into the brewing chamber and a coffee outlet pipe (12) which discharges the brewed coffee. In one embodiment, the coffee outlet pipe (12) is provided with a cream valve (13). The coffee outlet pipe (12) has a bottleneck (14) downstream to the cream valve (13). In another embodiment, the hot water supply (7) has a bottleneck (10).

Description

technical field [0001] The present invention relates to a brewing unit of a coffee machine, comprising a brewing cartridge containing ground coffee powder during brewing, a hot water supply mechanism leading into the brewing cartridge, and a coffee output pipeline for discharging brewed coffee. Furthermore, the invention relates to a coffee machine equipped with such a brewing unit. Background technique [0002] The coffee machine can provide freshly brewed coffee in portions, for example cups, and the coffee machine has a brewing unit. The brewing unit has a brewing cartridge into which ground coffee is fed after starting the brewing cycle, where it is compacted and then passed through hot water, from which extracted coffee grounds are then extracted. discharge. Depending on the design of the brewing unit, the brewing unit has at least two movable parts, wherein the movable parts are two relatively movable pistons, or one is a piston and the other is a brewing cartridge. ...
