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 may incorporate a window to permit visual observation of the fluidized bed therein.

Claims (38)

1. A coffee brewer, comprising:

a brew basket for receiving a quantity of ground coffee;

a plurality of jet ports for introducing a plurality of hot water streams into said brew basket, at least one of said jet ports being positioned to deliver a hot water stream into the brew basket at a location beneath the level of ground coffee contained therein, whereby the hot water streams introduced into said brew basket agitate and stir the coffee grounds to produce brewed coffee; and

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

said brew basket defining a plenum chamber in flow communication with said jet ports, and an open feed port for receiving a supply of hot water into said plenum chamber;

said brew basket having an upwardly open configuration defining a bottom wall and an upstanding side wall, said bottom wall defining said open feed port for receiving a supply of hot water into said plenum chamber, said side wall defining a plurality of hollow upstanding ribs in flow communication with said plenum chamber and each further defining at least one of said jet ports positioned to deliver a hot water stream into the brew basket at a location beneath the level of ground coffee contained therein.

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 means for directing the brewed coffee from said at least one filter element for flow into a coffee pot.

4. The coffee brewer of claim 1 wherein said brew basket further includes a substantially transparent window to permit visual observation of the water-agitated coffee grounds contained therein.

5. The coffee brewer of claim 1 wherein said jet ports are positioned and aimed for jetting water streams generally tangentially into said brew basket in a common swirling direction.

6. The coffee brewer of claim 1 wherein each of said hollow ribs defines a plurality of said jet ports, at least one of which is positioned to deliver a hot water stream into the brew basket at a location beneath the level of ground coffee contained therein.

7. The coffee brewer of claim 1 further including a brewer head defining an upwardly open brew cavity for removably receiving and supporting said brew basket, said brewer head further including a drip outlet port for guided drip flow passage of brewed coffee passing through said at least one filter element into a coffee pot.

8. The coffee brewer of claim 7 wherein said brewer head further includes a hot water inflow port for seated engagement with said brew basket feed port, when said brew basket is positioned within said brew cavity.

9. A coffee brewer, comprising:

a brew basket for receiving a quantity of ground coffee:

a plurality of jet ports for introducing a plurality of hot water streams into said brew basket, at least one of said jet ports being positioned to deliver a hot water stream into the brew basket at a location beneath the level of ground coffee contained therein, whereby the hot water streams introduced into said brew basket agitate and stir the coffee grounds to produce brewed coffee;

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

said brew basket defining a plenum chamber in flow communication with said jet ports, and an open feed port for receiving a supply of hot water into said plenum chamber;

a brewer head defining an upwardly open brew cavity for removably receiving and supporting said brew basket, said brewer head further including a drip outlet port for guided drip flow passage of brewed coffee passing through said at least one filter element into a coffee pot; and

further including a base platen for removably supporting a coffee pot in position for drip flow reception of brewed coffee passing through said drip outlet port.

10. The coffee brewer of claim 9 further including a support post for supporting said brewer head in spaced relation above said base platen.

11. The coffee brewer of claim 9 wherein said base platen further includes a heating element.

12. A coffee brewer, comprising:

a brew basket for receiving a quantity of ground coffee;

a plurality of jet ports for introducing a plurality of hot water streams into said brew basket, at least one of said jet ports being positioned to deliver a hot water stream into the brew basket at a location beneath the level of ground coffee contained therein, whereby the hot water streams introduced into said brew basket agitate and stir the coffee grounds to produce brewed coffee;

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

said brew basket defining a plenum chamber in flow communication with said jet ports, and an open feed port for receiving a supply of hot water into said plenum chamber; and

further including a reservoir for receiving a supply of water, a heating element, a first check valve for permitting unidirectional flow of water from said reservoir into heat exchange relation with said heating element to produce hot water, and a second check valve for permitting unidirectional flow of said hot water to said at least one jet port.

13. A coffee brewer, comprising:

a brew basket for receiving a quantity of ground coffee;

a plurality of hollow, generally upstanding ribs positioned within said brew basket, each of said ribs being coupled to a supply of hot water, and each of said ribs including at least one jet port for introducing a plurality of hot water streams into said brew basket, at least one of said jet ports on at least one of said ribs being positioned to deliver a hot water stream into the brew basket at a location beneath the level of ground coffee contained therein to agitate and stir the coffee grounds to produce brewed coffee; and

at least one filter element carried by said brew basket for passage of the brewed coffee substantially without passage of the coffee grounds.

14. The coffee brewer of claim 13 further including a brewer head defining an upwardly open brew cavity for removably receiving and supporting said brew basket.

15. The coffee brewer of claim 14 wherein said brewer head further defines a hot water inflow port for seated engagement with said brew basket and in flow communication with each of said hollow ribs, when said brew basket is positioned within said brew cavity.

16. The coffee brewer of claim 14 wherein said hollow ribs are positioned within said brew basket when said brew basket is positioned within said brew cavity.

17. The coffee brewer of claim 14 wherein said hollow ribs are formed integrally with said brew basket.

18. The coffee brewer of claim 13 wherein each of said hollow ribs includes at least one jet port positioned to deliver a hot water stream into the brew basket at a location beneath the level of ground coffee contained therein.

19. The coffee brewer of claim 13 wherein said jet ports are positioned and aimed for jetting water streams generally tangentially into said brew basket in a common swirling direction.
