Abstract

An automated coffee machine grinder features two grinding bodies that are rotatable relative to one another about a rotational grinding axis using a driveshaft device as well as an output opening for ground material arranged laterally of the grinding elements. The driveshaft device is positioned divergent from the rotational grinding axis. The output opening and the driveshaft device can be positioned differently relative to one another.

First claim

The invention claimed is:

1. A grinding device for grinding material to be ground, featuring
a first grinding element and
a second grinding element, as well as
an output opening device for ground material that is arranged laterally of the grinding elements,
wherein the first grinding element and the second grinding element are arranged with respect to each other so that a grinding slot located between the first grinding element and the second grinding element is provided,
wherein the first grinding element and the second grinding element are configured to be driven by means of a driveshaft device such that the first grinding element and the second grinding element rotate relative to one another about a rotational grinding axis and are enabled to pulverize material to be ground in the grinding slot during a rotation of the first grinding element and the second grinding element relative to one another about the rotational grinding axis,
wherein the driveshaft device is arranged divergent from the rotational grinding axis, and
wherein the output opening device and the driveshaft device are configured to be positioned in different positions relative to one another.

2. The grinding device according to claim 1 , wherein the output opening device and the driveshaft device are configured to be at least sectionally positioned in different positions relative to one another in a continuous fashion.

3. The grinding device according to claim 1 , wherein the output opening device and the driveshaft device are configured to be at least sectionally positioned in different positions relative to one another in an incremental fashion.

4. The grinding device according to claim 1 , wherein the different positioning of the output opening device and the driveshaft device relative to one another refers at least to an angular position of the output opening device and the driveshaft device relative to one another.

5. The grinding device according to claim 1 , wherein the grinding device features first and second subassemblies that are configured to be coupled to one another, wherein the first subassembly features the output opening device and the second subassembly features the driveshaft device ( 10 , 31 ).

6. The grinding device according to claim 1 ,
wherein the driveshaft device and the rotational grinding axis extend skewed to one another, and
wherein the driveshaft device and at least one of the first grinding element and the second grinding element are coupled to one another by means of a worm gear.

7. The grinding device according to claim 1 ,
wherein the driveshaft device and the rotational grinding axis are spaced apart from one another, and
wherein the driveshaft device and at least one of the first grinding element and the second grinding element are coupled to one another by a power transmission arrangement.

8. The grinding device according to claim 1 , comprising a position fixing device for fixing the position of the driveshaft device and the output opening device relative to one another.

9. The grinding device according to claim 8 , wherein the position fixing device is configured to interconnect the driveshaft device and the output opening device in at least one of a non-positively interlocking manner, a positively interlocking manner, and an integrally interlocking manner.

10. The grinding device according to claim 8 , wherein the position fixing device is realized in the form of a device that is configured to be handled separately and/or to cooperate with a device that is configured to be handled separately.

11. The grinding device according to claim 1 , comprising a drive unit configured to cause a rotational motion of the driveshaft device for enabling the first grinding element and the second grinding element to be driven by the driveshaft device such that the first grinding element and the second grinding element rotate relative to one another about the rotational grinding axis.

12. The grinding device according to claim 1 , comprising a brewing device for brewing ground material, wherein the brewing device is arranged with respect to the output opening device so that ground material is enabled to be fed from the output opening device to the brewing device.

13. The grinding device according to claim 1 , comprising just one and/or a multitude of output opening devices and/or wherein at least one output opening device is arranged in a radially outer region of at least one grinding element.

14. The grinding device according to claim 1 , comprising at least one grinder casing.

15. A coffee grinder, coffee machine or fully automated coffee machine featuring a grinding device according for grinding material to be ground comprising a first grinding element and a second grinding element, as well as an output opening device for ground material that is arranged laterally of the grinding elements, wherein the first grinding element and the second grinding element are configured to be driven by means of a driveshaft device such that the first grinding element and the second grinding element rotate relative to one another about a rotational grinding axis, wherein the driveshaft device is arranged divergent from the rotational grinding axis, and wherein the output opening device and the driveshaft device are configured to be positioned in different positions relative to one another.

16. The grinding device according to claim 8 , wherein the position fixing device is realized in the form of a reversible position fixing device.

17. The grinding device according to claim 8 , wherein the position fixing device is realized in the form of an irreversible position fixing device.

18. The grinding device according to claim 9 , wherein the position fixing device is realized in the form of an interlocking device configured to interlock in a clip-like and/or in a bayonet-like fashion.

19. The grinding device according to claim 11 , wherein the drive unit is configured as an electric motor.
