Unitary spray nozzle for a washing machine appliance
A unitary nozzle for a washing machine appliance includes an inlet body and an outlet body that are integrally formed together. The outlet body defines an outlet conduit with a first cross-sectional area at an entrance of outlet conduit and a second cross-sectional area at an exit of the outlet conduit. A shape of the second cross-sectional area is substantially arcuate. A related method for forming a unitary nozzle of a washing machine appliance is also provided.
1. A unitary spray nozzle for a washing machine appliance, comprising:
an inlet body defining a bend along a length of the inlet body, the inlet body further defining an inlet conduit configured for receiving a flow of wash fluid and directing the flow of wash fluid through the inlet body; and
an outlet body integrally formed within the inlet body and defining an outlet conduit, the outlet conduit being contiguous with the inlet conduit of the inlet body such that the outlet conduit is configured for receiving the flow of was fluid from the inlet conduit and directing the flow of wash fluid through the outlet body, the outlet conduit having a first cross-sectional area at an entrance of the outlet conduit and a second cross-sectional area at an exit of the outlet conduit, a shape of the second cross-sectional area being substantially arcuate, the shape of the second cross-sectional area being different than a shape of the first cross-sectional area.
2. The unitary spray nozzle of claim 1 , wherein the outlet body comprises a top plate and a bottom plate, the top plate and the bottom plate spaced apart from each other such that at least a portion of the outlet conduit is defined between the top plate and the bottom plate of the outlet body.
3. The unitary spray nozzle of claim 1 , wherein the top and bottom plates each have a partially spherical shape.
4. The unitary spray nozzle of claim 1 , wherein the inlet body and the outlet body are constructed of a single continuous piece of material.
5. The unitary spray nozzle of claim 4 , wherein the inlet body and the outlet body are constructed of a single continuous piece of plastic or metal.
6. The unitary spray nozzle of claim 1 , wherein the shape of first cross-sectional area is substantially hemispherical.
7. The unitary spray nozzle of claim 1 , wherein the inlet body is positioned above the outlet body at the entrance of the outlet body.
8. The unitary spray nozzle of claim 7 , wherein the entrance of outlet conduit is positioned above the exit of the outlet conduit.
9. The unitary spray nozzle of claim 1 , wherein the outlet conduit expands radially from the entrance of outlet to the exit of the outlet conduit.
10. The unitary spray nozzle of claim 1 , wherein the inlet conduit shifts between a circular cross-sectional shape and a semi-circular cross-sectional shape along the length of the inlet body.
11. A method for forming a unitary spray nozzle for a washing machine appliance, comprising: establishing three-dimensional information of the unitary spray nozzle; converting the three-dimensional information of the unitary spray nozzle from said step of establishing into a plurality of slices, each slice of the plurality of slices defining a respective cross-sectional layer of the unitary spray nozzle; and successively forming each cross-sectional layer of the unitary spray nozzle with an additive process; wherein, after said step of successively forming: (1) the unitary spray nozzle has an inlet body defining a bend along a length of the inlet body and also defines an inlet conduit and an outlet body defining an outlet conduit; (2) the outlet conduit is contiguous with the inlet conduit; (3) the outlet conduit having a first cross-sectional area at an entrance of outlet conduit and a second cross-sectional area at an exit of the outlet conduit, a shape of the second cross-sectional area being substantially arcuate; and (4) a shape of the second cross-sectional area is different than a shape of first cross-sectional area.
12. The method of claim 11 , wherein the additive process comprises at least one of fused deposition modeling, selective laser sintering, stereolithography, and digital light processing.
13. The method of claim 11 , wherein the shape of the second cross-sectional area is substantially arcuate after said step of successively forming.
14. The method of claim 11 , wherein the outlet body comprises a top plate and a bottom plate after said step of successively forming, the top plate and the bottom plate spaced apart from each other such that at least a portion of the outlet conduit is defined between the to plate and the bottom plate of the outlet body.
15. The method of claim 14 , wherein the top and bottom plates each have a partially spherical shape after said step of successively forming.
16. The method of claim 11 , wherein the shape of first cross-sectional area is substantially hemispherical after said step of successively forming.
17. The method of claim 11 , wherein the inlet body is positioned above the outlet body at the entrance of the outlet body after said step of successively forming.
18. The method of claim 17 , wherein the entrance of outlet conduit is positioned above the exit of the outlet conduit after said step of successively forming.
19. The method of claim 11 , wherein the outlet conduit expands radially from the entrance of outlet to the exit of the outlet conduit after said step of successively forming.
20. The method of claim 11 , wherein the unitary spray nozzle comprises a single continuous piece of plastic after said step of successively forming.
