Abstract

A system for brewing a desired portion of a beverage, such as a single-cup portion of coffee, is provided. The system may have more than one brew module. The system allows a user to quickly and easily brew a variety of types of single-cup portions of a beverage. In some embodiments, the system may brew a single-cup portion of coffee in a relatively short period of time based on a combination of certain parameters. The system may include an automatic cleaning mechanism such that a user does not need to manually clean components of a brewing machine between brew cycles. The system may also include apparatus configured to substantially prevent steam from reaching grinder components of the system. The system may also include apparatus configured to provide a precise dose of material based on, for example, volume of the material. Methods and apparatus for brewing a beverage are also disclosed.

First claim

What is claimed is:

1. An apparatus for brewing a beverage, the apparatus comprising:
at least one brew module configured to brew a single-cup portion of a beverage, the at least one brew module comprising a chamber configured to receive ground material and configured to engage with a nozzle;
wherein the chamber defines a first opening and a second opening, the first opening configured to receive ground material and the second opening configured to engage with the nozzle to direct a fan spray of liquid to one or more inner sidewalls of the chamber during a brew cycle;
wherein the second opening defines a plane across the second opening;
wherein the nozzle is configured to be inclined with respect to the plane across the second opening such that a face of the nozzle defines an angle between 5° and 60° with respect to the plane across the second opening;
wherein the nozzle is configured to direct liquid to an inner portion of the chamber during a brew cycle to agitate ground material during the brew cycle.

2. The apparatus of claim 1 , wherein the chamber comprises a plow feature configured to direct debris toward a waste bin.

3. The apparatus of claim 1 , wherein the chamber is configured to be removed from the brew module after a brew cycle.

4. The apparatus of claim 1 , wherein the face of the nozzle defines an angle between about 10° and 30° with respect to the plane across the second opening.

5. The apparatus of claim 1 , wherein the face of the nozzle defines an angle between about 15° and 20° with respect to the plane across the second opening.

6. The apparatus of claim 1 , wherein the at least one brew module further comprises a wiper assembly configured to automatically clean the at least one brew module.

7. The apparatus of claim 1 , wherein the apparatus further comprises a doser and a grinder, wherein the doser is configured to provide a precise amount of material to the grinder.

8. The apparatus of claim 7 , wherein the apparatus further comprises an upper subassembly configured to engage with the doser which is configured to engage with one or more hoppers.

9. The apparatus of claim 1 , wherein the ground material is ground coffee.

10. The apparatus of claim 1 , wherein the liquid is water.

11. The apparatus of claim 1 , wherein the apparatus is configured to brew at least three single-cup portions of coffee simultaneously.

12. The apparatus of claim 1 , wherein the apparatus for brewing a beverage comprises one brew module.

13. The apparatus of claim 1 , wherein the apparatus for brewing a beverage comprises two brew modules.

14. The apparatus of claim 1 , wherein the apparatus for brewing a beverage comprises three brew modules.

15. The apparatus of claim 1 , wherein the apparatus for brewing a beverage comprises four or more brew modules.
