Abstract

A coffee brewing system includes a brew vessel adapted to receive water and ground coffee to produce and store a brewed beverage and to provide for a cleaning system. The brew vessel includes a filter and a magnet stirrer in the lower portion of the brew vessel. The magnet stirrer creates a water vortex for brewing the coffee. The used coffee grounds are allowed to settle on the filter creating a bed of used coffee grounds and the coffee is then filtered through both the bed of used coffee grounds and the filter and collected in a coffee storage container. A cleaning system is used to remove unsightly coffee stains and oil films in the system after a brewing cycle.

Claims (21)

1. A method comprising:

producing heated water;

guiding the heated water via a water manifold into a coffee brewing chamber, wherein the coffee brewing chamber has a transparent portion;

using moving heated air, guiding coffee grounds into the coffee brewing chamber;

activating a magnetic stirrer within the coffee brewing chamber that creates a brewing vortex rotating about an axis of the magnetic stirrer;

brewing the heated water and the coffee grounds into brewed coffee within the brewing vortex;

upon deactivation of the magnetic stirrer, creating a second set of coffee grounds descending from within the brewed coffee onto a filter located within the coffee brewing chamber;

withdrawing the brewed coffee from the coffee brewing chamber through the set of second coffee grounds and the filter.

2. The method as in claim 1 , wherein the set of second coffee grounds have an increasing gradient of size.

3. The method as in claim 1 , wherein the water manifold guides a portion of the heated water from a plurality of nozzles installed within the top of the coffee brewing chamber.

4. The method as in claim 1 , further comprising:

producing soap water in a cleaning receptacle associated with the coffee brewing chamber;

guiding the soap water via the water manifold from the cleaning receptacle into the coffee brewing chamber;

activating the magnetic stirrer that creates a cleaning vortex rotating about the axis of the magnetic stirrer;

cleaning the coffee brewing chamber using at least the cleaning vortex.

5. The method as in claim 4 , wherein the soap water rises from the bottom of the coffee brewing chamber so that soap water rises above the filter.

6. The method as in claim 4 , wherein the soap water is produced via a soap key that may be selectively insertable to the cleaning receptacle and removable from the cleaning receptacle.

7. The method as in claim 6 , wherein the soap key comprises a plurality of selectively removable soap tablets.

8. The method as in claim 7 , wherein the water manifold guides a portion of the soap water from a plurality of nozzles installed within the top of the coffee brewing chamber.

9. The method as in claim 8 , wherein the water manifold guides a portion of the soap water from a plurality of nozzles installed within the top of the coffee brewing chamber so that the soap water cleans the coffee brewing chamber in a crisscross manner.

10. The method as in claim 4 , wherein the magnetic stirrer comprises a ball bearing.
