Abstract:
A coffee machine includes a grinding mill, a proportioning chamber arranged adjacent to the outlet of the grinding mill and a processing chamber, into which the coffee powder from the proportioning chamber is discharged. The coffee powder coming from the grinding mill is thrown into the proportioning chamber, which includes a pressure sensitive, elastically resilient wall element with a signal generator connected thereto. As soon as the proportioning chamber is filled with coffee powder, a dynamic pressure is built-up within the proportioning chamber due to the overpressure caused by the grinding mill, which forces the wall element to a displacement, whereby the signal generator is operated. Subsequently, on the one hand, the motor of the grinding mill is switched off and, on the other hand, a bottom wall part of the proportioning chamber is unlocked, whereby the milled product, assisted by the elastically resilient wall element, is discharged from the proportioning chamber.
