VARIABLE POSITION DIVERTER FOR AN APPLIANCE

摘要

A variable position diverter that provides wash fluid to selected combinations of outlet ports and spray assemblies. The diverter includes a housing having four fluid outlet ports, and a valve disk having a three apertures. The valve disk is rotated relative to the housing to align one or more of the three apertures with one or more of the four fluid outlet ports to selectively control the flow of wash fluid through corresponding spray assemblies. Selectively diverting wash fluid in this manner can improve wash performance and reduce cycle time while meeting government regulations regarding water usage.

1. A dishwasher appliance, comprising:
a wash chamber for receipt of articles for washing; a pump for providing fluid flow for cleaning the articles; and a diverter for selectively controlling the fluid flow to a plurality of spray assemblies, the diverter defining an axial direction, a radial direction, and a circumferential direction, the diverter comprising:
a housing;a fluid inlet for receiving fluid flow from the pump;a fluid outlet comprising four outlet ports, each of the four outlet ports being spaced apart by 90 degrees along the circumferential direction; anda valve positioned within the housing, the valve being rotatable along the circumferential direction, the valve comprising:
a disk defining a flange extending around a circumference of the disk and along the axial direction toward the fluid inlet, the disk further defining three apertures, the three apertures being positioned along the circumferential direction at 0, 90, and 225 degrees; anda positioning assembly configured to rotate the disk incrementally through eight angular positions, each of the eight angular positions being separated by 45 degrees.
