Systems for multi-channel conduits in dishwasher appliances

Abstract

A dishwasher appliance includes a tub that defines a wash chamber, and a diverter assembly at a bottom of the wash chamber. The dishwasher appliance also includes a wash conduit in the wash chamber. The wash conduit includes a first supply channel extending between the diverter assembly and a wash conduit outlet, and a second supply channel extending between the diverter assembly and an upper spray assembly. An inlet comprises both a first supply channel inlet and a second supply channel inlet. The first supply channel inlet and the second supply channel inlet are co-planar. The first supply channel inlet and the second supply channel inlet are different shapes.

What is claimed is: 
     
         1 . A dishwasher appliance, comprising,
 a tub defining a wash chamber;   a diverter assembly at a bottom of the wash chamber; and   a wash conduit in the wash chamber, the wash conduit comprising;
 a first supply channel extending between the diverter assembly and a wash conduit outlet, 
 a second supply channel extending between the diverter assembly and an upper spray assembly, and 
 an inlet comprising both a first supply channel inlet and a second supply channel inlet, the first supply channel inlet and the second supply channel inlet positioned co-planar, 
 wherein the first supply channel inlet and the second supply channel inlet are different shapes. 
   
     
     
         2 . The dishwasher appliance of  claim 1 , further comprising:
 a first rack assembly slidably positioned within the wash chamber;   a first spray assembly positioned in the wash chamber and configured to direct wash fluids at the first rack assembly;   a second rack assembly slidably positioned in the wash chamber above the first rack assembly;   a second spray assembly positioned in the wash chamber and configured to direct wash fluids at the second rack assembly;   a third rack assembly slidably positioned in the wash chamber above the second rack assembly; and   a third spray assembly positioned within the third rack assembly and configured to direct wash fluid at articles located in the third rack assembly.   
     
     
         3 . The dishwasher appliance of  claim 1 , wherein the first supply channel inlet is circular shaped. 
     
     
         4 . The dishwasher appliance of  claim 3 , wherein the second supply channel inlet is stadium shaped. 
     
     
         5 . The dishwasher appliance of  claim 4 , wherein the diverter assembly comprises a diverter outlet. 
     
     
         6 . The dishwasher appliance of  claim 5 , wherein the diverter assembly comprises a first diverter outlet and a second diverter outlet, the first diverter outlet coupled with the first supply channel inlet and the second diverter outlet coupled with the second supply channel inlet. 
     
     
         7 . The dishwasher appliance of  claim 6 , wherein the first diverter outlet is circular shaped to coupled with the first supply channel inlet and the second diverter outlet is stadium shaped to couple with the second supply channel inlet. 
     
     
         8 . A method of forming a wash conduit in a dishwasher appliance, the method comprising;
 blow molding a wash conduit, the wash conduit comprising a plurality of supply channels, and   concurrently trimming both the plurality of supply channels such that each end of the plurality of supply channels terminates on a common plane,   wherein each end of the plurality of supply channels is a different shape.   
     
     
         9 . The method of  claim 8 , wherein the plurality of supply channels of the wash conduit comprises a first supply channel and a second supply channel. 
     
     
         10 . The method of  claim 9 , wherein the first supply channel inlet is circular shaped. 
     
     
         11 . The method of  claim 10 , wherein the second supply channel inlet is stadium shaped.
