Grind size adjustment assembly comprising a coffee machine, coffee machine of an assembly of this type, and method for adjusting the grind size

A method for adjusting the grind size of a grind size adjustment assembly (1) having a coffee machine with a grinder and a control unit, comprising the method steps of

• (VS1) inputting a reference variable (target value) for a grind size of the grinder (2) into a force generation device (7a) of grinding tools (3, 4) of the grinder (2) of the coffee machine before operation or during operation of the grinder (2);
• (VS2) detecting forces or/and positions of the grinder (2) by means of a sensor device (12), generating a corresponding indication signal of force generation device (7a);
• and
• (VS3) comparing the indication signal thus obtained with the reference variable (target value) or with a reference variable obtained from a server (15), and setting the force generation device (7a) of the grinder (2) of the coffee machine for adjusting the grind size of the grind size adjustment assembly (1),
• wherein the control unit (10) has a regulating unit and, together with the sensor device (12) and the force generation device (7a) of the grinder (2), forms a control loop (16) configured for regulating the grind size of the grinder (2), and
• wherein the server (15) is designed in such a way that the server (15) transmits to the control unit (10) predetermined data for the force generation device (7a) of the grinder (2).

A method for telemetrically adjusting a grind of a grind size adjustment assembly comprising a coffee machine with at least one grinder and a control unit, and a server, comprising the method steps of

• (VS1) inputting a reference variable (target value) for a grind size of the grinder (2) before operation or during operation of the grinder (2) into a regulating unit of the control unit (10) or of the server (15) communicating with the control unit (10), wherein the regulating unit adjusts grinding tools (3, 4) of the grinder (2) via a force generation device (7a) via an actuating signal;
• (VS2) detecting forces or/and positions of the grinder (2) by means of a sensor device (12), generating a corresponding measuring signal (12b) and forwarding the measuring signal (12b) to the regulating unit;
• and
• (VS3) comparing the measuring signal (12b) thus obtained with the reference variable (target value) and forming a corresponding control signal for controlling the grind size of the grinder (2),
• wherein the regulating unit, together with the sensor device (12) and the force generation device (7a) of the grinder (2), forms a control loop (16) configured for regulating the grind size of the grinder (2), and
• wherein the server (15) is designed in such a way that the server (15) transmits to the control unit (10) predetermined data for the force generation device (7a) of the grinder (2).
