ABSTRACT:
A coffee machine (10) comprises a removable brewing unit (18), in which ground coffee powder is compacted in a brewing chamber along a main axis of the brewing unit (18) between a movable lifting bottom and a plunger that can be displaced toward the lifting bottom. Pressurized hot water is pressed through the compacted coffee powder. Afterwards, the lifting bottom and plunger are displaced together along the main axis in order to push the remaining filter cake out of the brewing chamber whereby ejecting it transversal to the main axis. The aim of the invention is to provide a coffee machine of the aforementioned type with a simplified and space-saving design as well as with an easier accessibility for cleaning and maintenance purposes. To these ends, the brewing unit (18) is designed so that it can be pushed into the coffee machine (10) from the front towards the back with the main axis parallel to the direction of insertion.
