ABSTRACT:
The cleaning of the brewing device of a coffee machine takes place in various phases. In a first phase, water is conducted out of a water tank via a water supply connection of the brewing cylinder through the outlet pipe disposed in the brewing piston into an external water tank. The cleaning water follows the route of the brewed coffee in this phase. In a second phase (see FIG. 3) the cleaning water is conducted from the brewing cylinder via channels in the wall of the brewing cylinder into areas outside the brewing cylinder and cleans, among other things, the second extension piece for the transport of the coffee grounds to the grounds container. In a third phase the water located in the brewing chamber is caused to flow out over the edge of the brewing cylinder by means of the shifting of the ejection piston. In a fourth phase a chemical or biological cleaning agent is introduced into the brewing chamber via the powder shaft, or from a cleaning agent tank, or from a water tank, or from a cartridge, water being conducted through afterwards, and this process repeated a few times. Finally there is a rinsing step.
