Spray arm assembly for a dishwasher appliance
A dishwasher appliance is provided with a spray arm assembly. The spray arm assembly defines an orifice for directing liquid out of the spray arm assembly. The orifice can selectively receive a nozzle with a particular outlet geometry. By selectively receiving the nozzle, a spray pattern of liquid exiting the orifice can be changed by replacing or modifying the nozzle without remanufacturing or replacing the spray arm assembly.
1. A spray assembly for a dishwasher appliance comprising:

a second nozzle inserted within another one of the plurality of orifices, the second nozzle having a second outlet geometry, the second outlet geometry being different from the first outlet geometry, wherein said first and second nozzles are configured for directing wash fluid out of the chamber of said spray arm; and
a sheet extending between said first nozzle and said second nozzle, said first nozzle and said second nozzle mounted to said sheet, said sheet disposed within the chamber of said spray arm.
2. The spray assembly of claim 1 , wherein said first nozzle is a first color and said spray arm is a second color, wherein the first color is different from the second color.
3. The spray assembly of claim 2 , wherein said second nozzle is a third color, wherein third color is different from the first and second colors.
4. The spray assembly of claim 1 , wherein the first outlet geometry comprises a pencil jet geometry and the second outlet geometry comprises a fan jet geometry.
5. The spray assembly of claim 1 , wherein the first outlet geometry comprises a pencil jet geometry with a first diameter and the second outlet geometry comprises a pencil jet geometry with a second diameter, wherein the first diameter is different than the second diameter.
6. The spray assembly of claim 1 , wherein the first outlet geometry comprises a pencil jet geometry that directs wash fluid in a first direction and the second outlet geometry comprises a pencil jet geometry that directs wash fluid in a second direction, wherein the first direction is different than the second direction.
7. The spray assembly of claim 6 , wherein said first nozzle or said second nozzle is heat staked, ultrasonically welded, over-molded, or co-molded to said spray arm.
8. The spray assembly of claim 1 , wherein said first and second nozzles are constructed of a rigid material.
9. The spray assembly of claim 1 , wherein said first and second nozzles are constructed of an elastic material.
