Spray arm for directing spray in a warewashing machine
An arm includes a tubular body that is rotatable. The tubular body has a first end portion, a second end portion and an intermediate portion between the first end portion and the second end portion. The first end portion is bent in a first direction forming a first angle with the intermediate portion, and the second end portion is bent in a second direction forming a second angle with the intermediate portion. A plurality of nozzles are through the tubular body.
1. A warewashing spray arm comprising:
a tubular body that is rotatable, said tubular body has a first end portion, a second end portion and an intermediate portion disposed between said first end portion and said second end portion, said first end portion being bent in a first direction forming a first angle with said intermediate portion, and said second end portion being bent in a second direction forming a second angle with said intermediate portion; and
a plurality of nozzles through said tubular body, at least a first nozzle of said plurality of nozzles being through said first end portion and at least a second nozzle of said plurality of nozzles being through said second end portion,
wherein said intermediate portion is rotatable in a plane of rotation about an axis of rotation, and
wherein said first end portion is bent in said first direction along a first vertical plane out of said plane of rotation so that said first nozzle initially directs fluid toward said axis of rotation and said second end portion is bent in said second direction along a second vertical plane out of said plane of rotation so that said second nozzle initially directs fluid away from said axis of rotation, and
wherein said first direction and said second direction are on opposite sides of said plane of rotation.
2. The arm of claim 1 , wherein said first angle is about 5 degrees to about 15 degrees.
3. The arm of claim 1 , wherein said second angle is about 5 degrees to about 15 degrees.
4. The arm of claim 1 , wherein said first end portion has a length of about 0.5 inches to about 5 inches.
5. The arm of claim 1 , wherein said second end portion has a length of about 0.5 inches to about 5 inches.
6. The arm of claim 1 , wherein said intermediate portion has a connector that rotatably connects the arm to a warewashing machine.
7. The arm of claim 1 , wherein said plurality of nozzles are positioned on said tubular body forming an angle with an axis through the arm between about 1 degree to about 45 degrees.
8. The arm of claim 1 , wherein said intermediate portion is unbent.
9. The arm of claim 1 , wherein said first end portion has a first amount of said plurality of nozzles that is greater than a second amount of said plurality of nozzles on said second end portion.
10. A warewashing machine comprising:
a spray arm having a tubular body that is rotatable, said tubular body has a first end portion, a second end portion and an intermediate portion disposed between said first end portion and said second end portion, said first end portion being bent in a first direction forming a first angle with said intermediate portion, and said second end portion being bent in a second direction forming a second angle with said intermediate portion, said spray arm having a plurality of nozzles through said tubular body; and
a rack that supports one or more wares that are contacted by a spray dispensed from said spray arm,
wherein said first end portion is bent in said first direction along a first vertical plane toward said rack, and
wherein said second end portion is bent in said second direction along a second vertical plane away from said rack.
11. The warewashing machine of claim 10 , wherein said spray arm is a first spray arm on a first side of said rack, and further comprising a second spray arm that is the same as said first arm positioned on a second side of said rack opposite said first side.
