Abstract

Apparatuses, systems, and methods for brewing a desired portion of a beverage, such as a single-cup portion of coffee, are provided. The system can include one or more hopper assemblies configured to provide a controlled dose of beverage material to a brew chamber. The system can also include a water input system configured to wet the ground beverage material as the grinds enter the brew chamber and substantially prevent steam from reaching grinder components of the system. Further, the system can include an automatic cleaning mechanism such that a user does not need to manually clean components of a brewing machine between brew cycles.

First claim

What is claimed is:

1. A brewing assembly for brewing coffee, the brewing assembly comprising:
a brew chamber configured to receive ground coffee;
a first fluid channel in fluid communication with the brew chamber; and
a mixing valve in fluid communication with the first fluid channel, the mixing valve comprising:
an outlet configured to deliver the ground coffee to the brew chamber; and
a number of passageways circumferentially disposed around the outlet, each of the number of passageways disposed at an angle greater than 0 degrees and less than 90 degrees relative to a longitudinal axis of the mixing valve such that the ground coffee mixes with water dispensed from the number of passageways as the ground coffee enters the brew chamber;

a dispensing outlet for dispensing brewed coffee, the dispensing outlet positioned downstream of the brew chamber.

2. The brewing assembly of claim 1 , wherein the angle is between 1 degree and 5 degrees.

3. The brewing assembly of claim 1 , further comprising a second fluid channel in fluid communication with the brew chamber, a fill nozzle in fluid communication with the second fluid channel.

4. The brewing assembly of claim 3 , wherein water delivered from the mixing valve has a first temperature and water delivered from the fill nozzle has a second temperature greater than the first temperature.

5. The brewing assembly of claim 1 , wherein the mixing valve comprises a ground coffee channel for delivering ground coffee to the brew chamber.

6. The brewing assembly of claim 5 , wherein the number of passageways are circumferentially disposed around the ground coffee channel.

7. The brewing assembly of claim 5 , wherein the mixing valve comprises a recessed portion disposed between at least one of the number of passageways and the ground coffee channel.

8. The brewing assembly of claim 5 , wherein the mixing valve includes a wall portion separating an outer recess and an inner recess, the inner recess comprising the number of passageways.
