ABSTRACT:
A coffee machine with an integrated coffee grinder and a powder chute, which serves the purpose of feeding ground coffee from the coffee grinder to a movable brewing cylinder, has an inlet with a manually operated lid for already ground special coffee. A sensor detects the position of the lid. The detection signal of the sensor is passed on to a processor controlling the coffee machine, and the signal is used to differentiate between a normal operating mode and an operating mode for producing special coffee. If the lid is opened for a certain minimum time span, a subsequent coffee preparation cycle in the operating mode for producing special coffee is initialized. Since, to that end, no separate pre-selection is required any longer, the operation of the coffee machine is simplified and the susceptibility to problems is reduced.
