Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In the following, the invention is described in more detail by means of exemplary embodiments with reference to the drawings, wherein:

[0011] FIG. 1: shows a schematic view of a grind size adjustment assembly according to the invention showing a front view in section of a principle of a grinder for grinding coffee beans; and

[0012] FIG. 2: shows a schematic view of the grind size adjustment assembly according to the invention with several coffee machines.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] FIG. 1 shows a schematic view of a grind size adjustment assembly 1 according to the invention with a front view in section of a principle of a grinder 2 for grinding coffee beans 7. FIG. 2 shows a schematic view of the grind size adjustment assembly 1 according to the invention with a plurality of coffee machines K1, K2, K3, Kn.

[0014] In this exemplary embodiment, the grind size adjustment assembly 1 comprises at least one grinder 2 of a coffee grinder or coffee machine K1, K2, K3, Kn and a remote control unit 10. The grind size adjustment assembly 1 may also comprise several coffee grinders, coffee machines, each having at least one grinder 2. This is illustrated in FIG. 2.

[0015] Here, the grinder 2 comprises a first grinding disc 3 and a second grinding disc 4 and a drive unit 6. Here, the second grinding disc 4 is driven by the drive unit 6, with the first grinding disc 3 being stationary. However, both grinding discs 3, 4 or the first grinding disc 3 can also be driven.

[0016] The grinder 2 further comprises at least one grind size adjustment device 5. The grind size adjustment device 5 effects an adjustment of a grind size of the grinding mechanism. For this purpose, the grind size adjustment device 5 may act on the first grinding disc 3 and change an adjustment of a distance between the first grinding disc 3 and the second grinding disc 4. In another embodiment, a force acting on the grinding disc 3, 4 to be adjusted can also be changed to adjust the grind size. Other embodiments are also possible, but will not be considered further here. The grind size adjustment device 5 can also act on the second rotatable grinding disc 4 or on both grinding discs 3, 4.

[0017] The grind size adjustment device 5 can be driven, for example, electromotively by a stepper motor or servomotor controlled by a control unit 8. The control unit 8 also controls an electric drive of the drive unit 6.

[0018] Here, the remote control unit 10 communicates with the control unit 8 and with the grind size adjustment device 5 connected thereto. The grind size adjustment device 5 may also have its own control unit (not shown).

[0019] The remote control unit 10 is coupled to the control unit 8 via a transmission link 11. The transmission link 11 can be wired or wireless, e.g., radio, infrared, ultrasound, Internet, WLAN, LAN, etc. It is also conceivable that the remote control unit 10 is a smartphone.

[0020] The grinder 2 can also have a sensor device 9, which determines a current setting value of the grind size adjustment device 5 and transmits it to the control unit 8, which in turn can also transmit this value to the remote control unit 10. This enables remote measurement, i.e. telemetric measurement, of the respective current setting value of the grind size adjustment device 5 of the grinder 2 belonging to a coffee machine K1, K2, K3, Kn. The value determined in this way can be used for further, different purposes, e.g. statistics, overview, regulations, etc.

[0021] In this way, telemetric access is provided for the remote control unit 10. The term “telemetric” access is to be understood here as meaning that the remote control unit 10 sends data for setting the grind size adjustment device 5 to the control unit 8 of the grinder 2 via the transmission link 11. In addition, data, for example measured values of the settings of the grind size setting device 5 can also be transmitted to the remote control unit 10 via the transmission link.

[0022] FIG. 2 shows a grind size adjustment assembly 1 with three coffee machines K1, K2, K3. The reference sign Kn is intended to indicate that further coffee machines Kn can also be assigned to the grind size adjustment assembly 1.

[0023] Coffee machine K1 has one grinder 2, whereas coffee machine K2 includes three grinders 2-1, 2-2, 2-3. Coffee machine K3 includes two grinders 2-1, 2-2. Of course, more grinders 2 than shown can also be assigned to the respective coffee machine K1, K2, K3. Each coffee machine K1, K2, K3 has a control unit 8 here.

[0024] This enables a central setting of individual or several grinders 2, 2-1,2-2, 2-3 to desired (e.g. identical) grind sizes and thus comparable product settings for achieving defined quality standards of several coffee machines K1, K2, K3, Kn (for example with so-called chain customers) by controlling the grinders 2, 2-1,2-2, 2-3 via the telemetric access by means of the remote control unit 10.

[0025] The grind size adjustment assembly 1 may also comprise a so-called stand-alone coffee grinder with a grinder 2. In this case, the associated control unit 8 may be part of the grinder 2.
