Abstract

A filter vessel for accommodating a filter insert made of water-permeable material and fillable with coffee grounds. The filter vessel includes a bottom; and side walls upwardly extending from the bottom and spreading outwardly. The bottom includes at least two openings through which a filtrate can pass. The bottom includes a separating element in a central region of the bottom. The separating element divides a region above the bottom into two approximately equal sized drainage chambers. Each drainage chamber includes at least one of the at least two openings for discharging the filtrate.

Claims (18)

1. A filter vessel for accommodating a filter insert made of water-permeable material and which is fillable with coffee grounds, the filter vessel comprising

a bottom including at least two openings through which a filtrate can pass; and

side walls upwardly extending from the bottom and spreading outwardly;

wherein the bottom includes a central region and a separating element in the central region of the bottom, the separating element dividing a region above the bottom into two approximately equal sized drainage chambers, and each drainage chamber including at least one opening-for discharging the filtrate; and

wherein the filter vessel has an underside, and further including a downwardly projecting web between the at least two openings on the underside of the filter vessel, wherein the downwardly projecting web extends parallel to the separating element.

2. The filter vessel according to claim 1 , wherein the separating element is adapted to support a lower edge of the filter insert when the filter insert is inserted into the filter vessel.

3. The filter vessel according to claim 1 , wherein the separating element is arranged to present a partition wall between the two drainage chambers.

4. The filter vessel according to claim 1 , wherein each drainage chamber has a bottom which descends towards the respective opening.

5. The filter vessel according to claim 4 , wherein each bottom has an inclination relative to a horizontal line at an angle between 3° and 30°.

6. The filter vessel according to claim 1 , wherein the spreading side walls of the filter vessel have an inner side that includes ribs extending towards the bottom.

8. The filter vessel according to claim 1 , wherein each drainage chamber includes at least one bottom rib extending from the separating element towards the at least one opening in each drainage chamber.

9. The filter vessel according to claim 8 , wherein the separating element has a height higher than the at least one bottom rib extending from the separating element in each drainage chamber.

10. The filter vessel according to claim 1 , further including a guide element for the filtrate disposed in each opening.

11. The filter vessel according to claim 1 , wherein the filter vessel has an underside including a support plate having a downwardly facing edge.

12. The filter vessel according to claim 11 , wherein the support plate and/or the edge has a recess or a viewing window.

13. A filter vessel according to claim 1 , wherein the underside further includes at least two approximately radially oriented support webs, relative to one of the openings, and having lower edges defining a plane, the underside further including at least one web adjoining the downward projecting web and having a lower edge vertically offset upwardly relative to the downwardly projecting web between the two openings and located in the same plane as the lower edges of the two approximately radially oriented webs.

14. The filter vessel according to claim 1 , wherein the filter vessel has an underside, and further including a tubular or U-shaped rib arranged around each opening on the underside of the filter vessel.
