Abstract

Please substitute the following paragraph(s) for the abstract now appearing in the currently filed specification:

A machine and a method for the preparation of a hot drink with a housing, a water tank and a reclosable brewing chamber, which can be charged and emptied in the opened state. In order to improve handling, the brewing chamber can be completely removed from the housing for charging, emptying and cleaning.

Claims

1. Machine (1) for the preparation of a hot drink, comprising a housing (11), a water tank (7) and a reclosable and refillable brewing chamber (3), and wherein the brewing chamber (3) can be completely removed from the housing for charging, emptying and cleaning.

2. Machine (1) according to claim 1, wherein the brewing chamber (3) comprises an upper part (3b) and a lower part (3a).

3. Machine according to claim 2, wherein the upper part (3b) and the lower part (3a) are joined by a locking mechanism (24).

4. Machine according to claim 1, wherein the housing (11) has a drawer compartment (22), into which the brewing chamber (3) can be inserted as a complete unit.

5. Machine according to claim 4, wherein the dimensions of the drawer compartment (22) are formed such that the upper side of the upper part (3b) and the underside of the lower part (3a) contact the drawer compartment (22) at least partially.

6. Machine according to claim 4, wherein the dimensions of the drawer compartment (22) are formed such that the brewing chamber (3) contacts the drawer compartment (22) at the side.

7. Machine according to claim 2, wherein a joint gap (19) between the upper part (3b) and the lower part (3a) is sealed by an internal seal (20).

8. Machine according to claim 1 the brewing chamber (3) has a section through which brewing water can be passed, wherein in this region a seal (16) is provided between the brewing chamber (3) and the housing (11).

9. Machine according to claim 1, wherein the brewing chamber (3) has a coding (33), which indicates a certain type of brewing chamber, and a sensor device (32) is provided which acquires the coding.

10. Machine according to claim 9, wherein the machine (1) has a controller (13), which controls the brewing process in dependence of the acquired coding (33).

11. Machine according to claim 1, wherein the machine (1) has a region (9) for inserting a container (2).

12. Machine according to claim 11, wherein the drawer compartment is arranged one of in or above the region (9) for inserting a container.

13. Machine according to claim 1, wherein the brewing chamber (3) protrudes over an outer side of the housing (11).

14. Machine according to claim 1, and several different brewing chambers of a different type, each different brewing chamber being designed for a medium to be processed.

15. Machine according to claim 14, wherein the different types of brewing chambers each have an appropriate coding (33).

16. Method of preparing a hot drink with a machine (1) according to claim 1, and opening the brewing chamber (3), which is removed as a complete unit from the housing (11) and charging the brewing chamber (3) with the medium (23) to be brewed,

closing and inserting the brewing chamber (3) into the machine housing (11) as a complete unit,

passing brewing water into the brewing chamber (3) under pressure, and

passing out the prepared hot drink of the brewing chamber (3).

17. Method according to claim 16, and removing the brewing chamber (3) from the housing (11) as a complete unit and opening the brewing chamber (3) for emptying the medium.
