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 (41)

1. A system comprising:

a coffee brewing chamber;

a coffee chute associated with the coffee brewing chamber having coffee grounds;

a water manifold for guiding heated water into the coffee brewing chamber;

an air flow chamber for guiding moving air into the coffee brewing chamber;

a magnetic stirrer within the coffee brewing chamber rotating about a stirrer axis;

wherein the moving air guides the coffee grounds from the coffee chute into the coffee brewing chamber;

wherein activation of the magnetic stirrer creates a brewing vortex rotating about the stirrer axis that brews the heated water and the coffee grounds into brewed coffee;

wherein the coffee brewing chamber has a transparent portion;

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.

2. The system as in claim 1 , wherein the coffee grounds comprise a set of second coffee grounds that settle at a bottom of the coffee brewing chamber upon deactivation of the coffee brewing chamber.

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

4. The system as in claim 3 , wherein the brewed coffee is withdrawn from the coffee brewing chamber through the set of second coffee grounds.

5. The system as in claim 3 , wherein the set of second coffee grounds acts as a filter for the brewed coffee.

6. The system as in claim 1 , wherein release of the portion of the heated water occurs radially.

7. The system as in claim 6 , wherein the portion of the heated water cleans the transparent portion.

8. The system as in claim 1 , wherein the activation and deactivation of the magnetic stirrer uses a modulation pattern.

9. The system as in claim 1 , wherein the air flow chamber draws the moving air over heated elements to heat the moving air.

10. The system as in claim 9 , wherein the air flow chamber further comprises a fan to force the moving air into the coffee brewing chamber.

11. The system as in claim 1 , wherein increasing and decreasing speed of the magnetic stirrer produces the brewing vortex of varying height.

12. A system comprising:

a coffee brewing chamber;

a coffee chute associated with the coffee brewing chamber having coffee grounds;

a water manifold for guiding heated water into the coffee brewing chamber;

an air flow chamber for guiding moving air into the coffee brewing chamber;

a magnetic stirrer within the coffee brewing chamber rotating about a stirrer axis;

wherein the moving air guides the coffee grounds from the coffee chute into the coffee brewing chamber;

a flexible accumulator for uptake of excess liquid,

wherein activation of the magnetic stirrer creates a brewing vortex rotating about the stirrer axis that brews the heated water and the coffee grounds into brewed coffee;

wherein the coffee brewing chamber has a transparent portion.

13. A system comprising:

a coffee brewing chamber;

a coffee chute associated with the coffee brewing chamber having coffee grounds;

a water manifold for guiding heated water into the coffee brewing chamber;

an air flow chamber for guiding moving air into the coffee brewing chamber;

a magnetic stirrer within the coffee brewing chamber rotating about a stirrer axis;

wherein the moving air guides the coffee grounds from the coffee chute into the coffee brewing chamber;

wherein activation of the magnetic stirrer creates a brewing vortex rotating about the stirrer axis that brews the heated water and the coffee grounds into brewed coffee;

wherein the coffee grounds comprise a set of second coffee grounds that settle at a bottom of the coffee brewing chamber upon deactivation of the coffee brewing chamber;

a mesh fabric upon which the set of second coffee grounds settle;

wherein the coffee brewing chamber has a transparent portion.
