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 for use in a warewashing system including a rack for wares, the warewashing system being in fluid communication with a fluid source, comprising:

a tubular body connected to the fluid source, the tubular body including a wall forming an arch with a convex side facing upwardly and a concave side facing downwardly, the arch extending along a length of the tubular body, the tubular body having at least a first aperture and a second aperture therethrough, the first aperture forming a first spray and the second aperture forming a second spray when the fluid flows through the tubular body from the fluid source, the first aperture having a first aperture axis therethrough and the second aperture having a second aperture axis therethrough, the first aperture axis forming a first angle with a first vertical axis and the second aperture axis forming a second angle with a second vertical axis, and the first angle being 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, wherein the arch is a continuous curved shape and the first aperture axis and the second aperture axis are perpendicular to the wall of the tubular body so that the first angle of the first aperture axis and the second angle of the second aperture axis are determined by the continuous curved shape of the arch.

2. The rinse arm of claim 1, the first aperture and the second aperture being positioned along the length of the tubular body so that the overlapping spray extends across an entirety of a width of the rack holding wares.

3. The rinse arm of claim 1, the tubular body further comprising a third aperture therethrough, the third aperture forming a third spray and having a third aperture axis therethrough, the third aperture axis forming a third angle with a third vertical axis, the third angle being greater than 0 degrees so that the third aperture directs third spray toward the second spray forming an overlapping spray of at least the first spray, the second spray, and the third spray, the first aperture, the second aperture, and the third aperture being positioned along the length of the tubular body so that the overlapping spray extends across an entirety of a width of the rack holding wares.

4. A wash arm use in a warewashing system including a rack for wares, the warewashing system being in fluid communication with a fluid source, comprising:

a tubular body connected to a fluid source, the tubular body including a wall forming an arch with a convex side facing upwardly and a concave side facing downwardly, the arch extending along a length of the tubular body, the tubular body having at least a first aperture and a second aperture therethrough, the first aperture forming a first spray and the second aperture forming a second spray when the fluid flows through the tubular body from the fluid source, the first aperture having a first aperture axis therethrough and the second aperture having a second aperture axis therethrough, wherein the first aperture axis and the second aperture axis intersect a vertical axis that passes through an apex of the arch at a first angle and a second angle, respectively, 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, wherein the arch is a continuous curved shape and the first aperture axis and the second aperture axis are perpendicular to the wall of the tubular body so that the first angle of the first aperture axis and the second angle of the second aperture axis are determined by the continuous curved shape of the arch.

5. A warewashing system comprising:

a housing;

a rack holding a plurality of wares in the housing;

a rack support that supports the rack in the housing; and

a tubular body connected to a fluid source, the tubular body including a wall forming an arch with a convex side facing upwardly and a concave side facing downwardly, the arch extending along a length of the tubular body, the tubular body having at least a first aperture and a second aperture therethrough, the first aperture forming a first spray and the second aperture forming a second spray when the fluid flows through the tubular body from the fluid source, the first aperture having a first aperture axis therethrough and the second aperture having a second aperture axis therethrough, the first aperture axis forming a first angle with a first vertical axis and the second aperture axis forming a second angle with a second vertical axis, and the first angle being 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 contacting the wares, wherein the arch is a continuous curved shape and the first aperture axis and the second aperture axis are perpendicular to the wall of the tubular body so that the first angle of the first aperture axis and the second angle of the second aperture axis are determined by the continuous curved shape of the arch.

6. The warewashing system of claim 5, wherein the warewashing system is a conveyorized warewashing system, and wherein the rack support is a conveyor.

7. The warewashing system of claim 5, wherein the tubular body rotates.

8. The warewashing system of claim 5, wherein the fluid passing through the tubular body out the apertures has a pressure of 15 pounds per square inch gauge (psig) to 30 psig.

9. The warewashing system of claim 5, the first aperture and the second aperture being positioned along the length of the tubular body so that the overlapping spray extends across an entirety of a width of the rack holding wares.

10. The warewashing system of claim 5, the tubular body further comprising a third aperture therethrough, the third aperture forming a third spray and having a third aperture axis therethrough, the third aperture axis forming a third angle with a third vertical axis, the third angle being greater than 0 degrees so that the third aperture directs third spray toward the second spray forming an overlapping spray of at least the first spray, the second spray, and the third spray, the first aperture, the second aperture, and the third aperture being positioned along the length of the tubular body so that the overlapping spray extends across an entirety of a width of the rack holding wares.
