Abstract

A brewing apparatus including a housing having a movable lid; a water heater connected to the housing; and a hot water discharge head connected to the lid for delivering hot water from the hot water heater in a downward direction. The hot water discharge head includes at least two arrays of water discharge holes including a first center array of smaller holes and a second surrounding array of larger holes.

Claims (31)

1. A brewing apparatus comprising:

a housing having a movable lid;

a water heater connected to the housing; and

a hot water discharge head connected to the lid for delivering hot water from the hot water heater in a downward direction, the hot water discharge head comprising at least two arrays of water discharge holes comprising a first center array of smaller holes and a second surrounding array of larger holes, wherein each of the second set of holes are at least 50 percent larger than the first set of holes to direct more of the water through the second set of holes then through the first set of holes.

2. A brewing apparatus as in claim 1 wherein the lid is pivotable between an up position and a down position, and wherein the hot water discharge head is stationarily connected to the lid.

3. A brewing apparatus as in claim 1 wherein the second array of larger holes comprises two concentric rings of the larger holes.

4. A brewing apparatus as in claim 3 wherein the first array of smaller holes comprises four of the smaller holes, a first one of the concentric rings comprises four of the larger holes, and a second one of the concentric rings comprises four of the larger holes.

5. A brewing apparatus as in claim 4 wherein the first concentric ring of larger holes has a same pattern as the first array of smaller holes, but is axially rotated relative to the first array about 45 degrees.

6. A brewing apparatus as in claim 5 wherein the second concentric ring of larger holes has a same pattern as the first array and is aligned with the first array.

7. A brewing apparatus as in claim 1 wherein the second surrounding array of larger holes comprises a first set of the larger holes located closer to the first array of smaller holes than a second set of the larger holes, and wherein the second set of larger holes are offset about 45 degrees relative to the first set of larger holes.

8. A brewing apparatus as in claim 1 wherein each of the second set of holes are at least about 75 percent larger than the first set of holes.

9. A brewing apparatus as in claim 1 further comprising a seal connected to an outer side perimeter of the hot water discharge head.

10. A brewing apparatus hot water discharge head comprising:

a first center water discharge outlet system comprising at least one smaller water discharge hole located in a center region of a bottom side of the discharge head; and

a second outer water discharge outlet system comprising a set of larger water discharge holes located generally radially outward relative to the at least one water discharge hole,

wherein the total area of the set of larger holes is larger than the total area of the at least one smaller hole such that more water passes through the second outer water discharge outlet system than the first center water discharge outlet system during each brew cycle.

11. A brewing apparatus hot water discharge head as in claim 10 wherein each of the second set of holes are at least about 50 percent larger than the first set of holes.

12. A brewing apparatus hot water discharge head as in claim 10 wherein each of the second set of holes are at least about 75 percent larger than the first set of holes.

13. A brewing apparatus hot water discharge head comprising:

a first center water discharge outlet system comprising at least one water discharge hole located in a center region of a bottom side of the discharge head; and

a second outer water discharge outlet system comprising a set of water discharge holes located generally radially outward relatiye to the at least one water discharge hole,

wherein the total area of the set of holes is larger than the total area of the at least one hole such that more water passes through the second outer water discharge outlet system than the first center water discharge outlet system during each brew cycle;

wherein the second outer water discharge outlet system comprises an array of the larger holes arranged in two concentric rings.

14. A brewing apparatus hot water discharge head as in claim 13 wherein the first set of smaller holes comprises four of the smaller holes, a first one of the concentric rings comprises four of the larger holes, and a second one of the concentric rings comprises four more of the larger holes.

15. A brewing apparatus hot water discharge head as in claim 14 wherein the first concentric ring of larger holes has a same pattern as the first set of smaller holes, but is axially rotated relative to the first set about 45 degrees.

16. A brewing apparatus hot water discharge head as in claim 14 wherein the second concentric ring of larger holes has a same pattern as the first set and is aligned with the first set.

17. A brewing apparatus hot water discharge head comprising:

a first center water discharge outlet system comprising at least one water discharge hole located in a center region of a bottom side of the discharge head; and

a second outer water discharge outlet system comprising a set of water discharge holes located generally radially outward relative to the at least one water discharge hole,

wherein the total area of the set of holes is larger than the total area of the at least one hole such that more water passes through the second outer water discharge outlet system than the first center water discharge outlet system during each brew cycle;

wherein the second outer water discharge outlet system comprises a first subset of larger holes located closer to the first center water discharge outlet system than a second subset of larger holes, and wherein the second subset of larger holes are axially rotated about 45 degrees relative to the first subset of larger holes.
