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 (11)

1. A system comprising:

a coffee brewing chamber;

a cleaning receptacle associated with the coffee brewing chamber having a soap key that may be selectively insertable to the cleaning receptacle and removable from the cleaning receptacle;

a water manifold at least partially within the cleaning receptacle for guiding soap water within the coffee brewing chamber;

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

wherein activation of the magnetic stirrer creates a cleaning vortex rotating about the stirrer axis that cleans the coffee brewing chamber;

wherein the soap key comprises a plurality of selectively removable soap tablets.

2. The system as in claim 1 , further comprising:

a mesh fabric at the bottom of the coffee brewing chamber.

3. The system as in claim 2 , wherein the water manifold guides a portion of the soap water through the bottom of the coffee brewing chamber so that the soap water rises above the mesh fabric.

4. The system as in claim 2 , 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.
