The invention relates to a brewing device for a coffee machine, comprising a filter retainer (3), which holds a retention filter (6) for ground coffee beans and which is designed in particular as a filter carrier, a brewing cylinder (4), which can be moved relative to the filter retainer (3) between a loading position for ground coffee beans and a brewing position and which bounds a brewing chamber (13) together with the retention filter (6) of the filter retainer (3) in the brewing position, which brewing chamber has an inlet for pressurized brewing water, wherein a brewing chamber bottom can be moved within the brewing cylinder and the brewing cylinder can be moved into the loading position relative to a scraper in a movement step in order to scrape a cake of used grounds from the brewing chamber, and a cleaning element (7) for removing used coffee grounds adhering to the retention filter (6) after a brewing process during a cleaning motion. According to the invention, the filter retainer (3) and the cleaning element (7) are spring-loaded toward each other in such a way that the cleaning element (7) touches the retention filter (6) and/or the filter retainer (3) during the cleaning motion of the cleaning element and thereby scrapes off the adhering used coffee grounds, and the cleaning element (7) is spring-loaded away from the brewing cylinder in the direction of the retention filter (6), in particular upward, by means of a first compression spring (11) during the cleaning motion. |
