Abstract

A rinse arm or wash arm includes a tubular body connected to a fluid source. The tubular body has at least a first aperture and a second aperture therethrough. The first aperture forms a first spray and the second aperture forms a second spray when the fluid flows through the tubular body from the fluid source. The first aperture has a first aperture axis therethrough and the second aperture has a second aperture axis therethrough. The first aperture axis forms a first angle with a first vertical axis and the second aperture axis forms a second angle with a second vertical axis. The first angle is greater than 0 degrees, so that the first aperture directs the first spray towards the second spray forming an overlapping spray of the first spray and the second spray.

Claims

1. A rinse arm comprising:

a tubular body having a length and being connected to a fluid source, said tubular body having at least a first aperture, a second aperture, and a third aperture therethrough, said first aperture forming a first spray, said second aperture forming a second spray, and said third aperture forming a third spray when said fluid flows through said tubular body from said fluid source, said first aperture having a first aperture axis therethrough, said second aperture having a second aperture axis therethrough, and said third aperture having a third aperture axis therethrough, said first aperture axis forming a first angle with a first vertical axis, said second aperture axis forming a second angle with a second vertical axis, and said third aperture axis forming a third angle with a third vertical axis, and at least said first angle and said third angle being greater than 0 degrees, so that said first aperture and said third aperture direct said first spray and said third spray toward said second spray forming an overlapping spray of at least said first spray, said second spray, and said third spray, said first aperture, said second aperture, and said third aperture being positioned along said length of said tubular body so that said overlapping spray can extend across an entirety of a width of a rack holding a plurality of wares.

2. The rinse arm of claim 1, wherein said tubular body is an arched shape along a length of said tubular body.

3. The rinse arm of claim 2, wherein said tubular body is curved to form said arched shape.

4. The rinse arm of claim 2, wherein said tubular body is a plurality of segments that are connected to form said arched shape, and wherein each of said plurality of segments is straight.

5. The rinse arm of claim 1, wherein said tubular body is straight along said length of said tubular body, wherein each of said first aperture and said second aperture has a nozzle wall, and wherein at least one of said nozzle walls is connected to said tubular body so that it is non-perpendicular to said tubular body.

6. The rinse arm of claim 1, further comprising a warewashing system connected to the rinse arm, and wherein said warewashing system connected to the rinse arm has a water consumption of 70 gallons per hour.

7. The rinse arm of claim 1, wherein said first aperture and said third aperture are on opposite sides of said second aperture.

8. The rinse arm of claim 1, further comprising a warewashing system connected to the rinse arm, and wherein said warewashing system connected to the rinse arm uses 0.38 gallons of water per rack.

9. A wash arm comprising:

a tubular body having a length and being connected to a fluid source, said tubular body having at least a first aperture, a second aperture, and a third aperture therethrough, said first aperture forming a first spray, said second aperture forming a second spray, and said third aperture forming a third spray when said fluid flows through said tubular body from said fluid source, said first aperture having a first aperture axis therethrough, said second aperture having a second aperture axis therethrough, and said third aperture having a third aperture axis therethrough, said first aperture axis forming a first angle with a first vertical axis, said second aperture axis forming a second angle with a second vertical axis, and said third aperture axis forming a third angle with a third vertical axis, and at least said first angle and said third angle being greater than 0 degrees, so that said first aperture and said third aperture direct said first spray and said third spray toward said second spray forming an overlapping spray of at least said first spray, an said second spray, and said third spray, said first aperture, said second aperture, and said third aperture being positioned along said length of said tubular body so that said overlapping spray can extend across an entirety of a width of a rack holding a plurality of wares.

10. The wash arm of claim 9, wherein said tubular body is an arched shape along a length of said tubular body.

11. The wash arm of claim 10, wherein said tubular body is curved to form said arched shape.

12. The wash arm of claim 10, wherein said tubular body is a plurality of segments that are connected to form said arched shape, and wherein each of said plurality of segments is straight.

13. The wash arm of claim 9, wherein said tubular body is straight along said length of said tubular body, wherein each of said apertures has a nozzle wall, and wherein at least one of said nozzle walls is connected to said tubular body so that it is non-perpendicular to said tubular body.

14. The wash arm of claim 9, wherein said first aperture and said third aperture are on opposite sides of said second aperture.

15. A warewashing system comprising:

a housing;

a rack holding a plurality of wares in said housing;

a rack support that supports said rack in said housing, said rack having a width; and

a tubular body connected to a fluid source, said tubular body having at least a first aperture, a second aperture, and a third aperture therethrough, said first aperture forming a first spray, said second aperture forming a second spray, and said third aperture forming a third spray when said fluid flows through said tubular body from said fluid source, said first aperture having a first aperture axis therethrough, and said second aperture having a second aperture axis therethrough, and said third aperture having a third aperture axis therethrough, said first aperture axis forming a first angle with a first vertical axis, said second aperture axis forming a second angle with a second vertical axis, and said third aperture axis forming a third angle with a third vertical axis, and at least said first angle and said third angle being greater than 0 degrees, so that said first aperture and said third aperture directs direct said first spray and said third spray toward said second spray forming an overlapping spray of at least said first spray, said second spray, and said third spray contacting said wares, said overlapping spray extending across an entirety of said width of said rack.

16. The warewashing system of claim 15, wherein the warewashing system is a conveyorized warewashing system, and wherein said rack support is a conveyor.

17. The warewashing system of claim 15, wherein said tubular body rotates.

18. The warewashing system of claim 15, wherein said fluid passing through said tubular body out said apertures has a pressure of 15 pounds per square inch gauge (psig) to 30 psig.

19. The warewashing system of claim 15, wherein said first aperture and said third aperture are on opposite sides of said second aperture.
