ABSTRACT:
An automatic coffee machine (1) includes a sliding block (28) fixedly connected to a housing (2). A brewing unit (5) includes an upper and a lower locking element (7, 8) and a vertical tube section (4). The upper locking element (7) is alternately moved in a brewing position, a stand-by position and a parking position. The upper locking element (7) in the brewing position protrudes into the tube section (4) to attain a brewing chamber (6). The upper locking element (7) in the stand-by position does not protrude into the tube section (4) and the axis of the upper locking element (7) is aligned with the axis (9) of the tube section (4). The upper locking element (7) in the parking position does not protrude into the tube section (4) and the axis of the upper locking element (7) is not aligned with the axis (9) of the tube section (4). A pivot column (15) connected to the upper locking element (7) is moved in an axial direction, and it is rotated about its axis. The pivot column (15) includes a sliding path (23) including a first portion (24) parallel to the axis of the pivot column (15) and a second portion (25) extending in a way similar to a thread. The sliding block (28) engages the first portion (24) to alternately attain the brewing position and the stand-by position. The sliding block (28) engages the second portion (25) to alternately attain the stand-by position and the parking position.
