Abstract

An improved coffee brewer and brewing method are provided for producing brewed coffee with improved flavor. The coffee brewer includes a brew basket having jet ports connected to a source of heated water and positioned to deliver hot water streams into the brew basket at a location beneath the level of coffee grounds contained therein. These hot water streams turbulently agitate and stir the coffee grounds to produce a substantially fluidized bed of water-borne coffee grounds for improved flavor extraction and enhanced aroma. This fluidized bed is directed against one or more mesh filter elements forming a wall portion of the brew basket for outward passage of the thus-brewed coffee which is then directed into an underlying carafe or the like. In one preferred form, a portion of the brew basket incorporates an illuminated window to permit visual observation of the fluidized bed therein.

Claims (28)

1. A coffee brewer, comprising:

a brew basket for receiving a quantity of ground coffee;

at least one water inflow port for introducing at least one hot water stream into said brew basket for contacting the ground coffee to produce brewed coffee;

said brew basket further including a substantially transparent window to permit visual observation of the ground coffee contained therein;

a light for illuminating at least a portion of said brew basket for external viewing through said window; and

at least one filter element for passage of the brewed coffee substantially without passage of the ground coffee;

said at least one water inflow port being positioned for introducing said at least one hot water stream into the brew basket at a location within the ground coffee contained therein, whereby the at least one hot water stream agitates and stirs the ground coffee, said transparent window and said light accommodating external viewing of the water-agitated ground coffee during a brew cycle;

said light being spaced at least a short distance from said window and cooperating therewith to define a chamber therebetween for receiving a portion of the water-agitated coffee grounds during a brew cycle, said light back-illuminating said portion of the water-agitated coffee grounds.

2. The coffee brewer of claim 1 wherein said at least one filter element defines a wall portion of said brew basket.

3. The coffee brewer of claim 1 further including a brewer head defining a brew cavity for removably receiving and supporting said brew basket.

4. The coffee brewer of claim 3 wherein said brew cavity further defines a forwardly open geometry with a generally U-shaped arcuate recess, said light being positioned generally at a lower margin of said arcuate recess.

5. The coffee brewer of claim 4 wherein said brew basket includes a frontal segment including a forwardly protruding shoulder having a size and shape for seated reception generally within said arcuate recess, and a substantially transparent front window, said shoulder further defining a pocket for slide-fit reception of said light, said pocket being spaced at least a short distance from said window and cooperating therewith to define a chamber therebetween, said light back-illuminating said chamber.

6. The coffee brewer of claim 5 wherein said pocket is translucent.

7. The coffee brewer of claim 1 wherein said brew basket is upwardly open, and further including a cap movable between an open position to permit coffee grounds to be received into and removed from said brew basket, and a closed position during a brew cycle, said cap in said closed position carrying said light in a position spaced from said window and cooperating therewith to define said chamber therebetween.

8. The coffee brewer of claim 1 wherein said light comprises an LED.

9. The coffee brewer of claim 1 wherein said light comprises a translucent bulb body.

10. The coffee brewer of claim 1 wherein said light comprises a frosted bulb.

11. The coffee brewer of claim 1 further including a light control circuit for respectively turning the light on and off upon initiation and completion of a brew cycle.

12. The coffee brewer of claim 11 including a sensor for detecting completion of a brew cycle and for signaling said light control circuit.

13. A coffee brewer, comprising:

a brew basket for receiving a quantity of ground coffee;

a brewer head defining a brew cavity for removably receiving and supporting said brew basket;

at least one water inflow port for introducing at least one hot water stream during a brew cycle into said brew basket at a location within the ground coffee contained therein, whereby the at least one hot water stream agitates and stirs the ground coffee to produce brewed coffee;

said brew basket further including a frontal segment having a substantially transparent front window to permit visual observation of the ground coffee contained therein;

a light positioned within said brew basket during a brew cycle and spaced at least a short distance from said window and cooperating therewith to define a chamber therebetween for circulation of at least a portion of the water-agitated ground coffee during a brew cycle, said light back-illuminating said chamber; and

at least one filter element for passage of the brewed coffee substantially without passage of the ground coffee.

14. The coffee brewer of claim 13 further including a light control circuit for respectively turning the light on and off upon initiation and completion of a brew cycle.

15. The coffee brewer of claim 14 including a sensor for detecting completion of a brew cycle and for signaling said light control circuit.
