Abstract
A dishwasher appliance includes a wash tub that defines a wash chamber, a sump for collecting wash fluid, a wash pump assembly in fluid communication with the sump for circulating the wash fluid, a diverter assembly fluidly coupled to the wash pump assembly for selectively directing the wash fluid, and a hydraulic manifold assembly fluidly coupled to the diverter assembly. The hydraulic manifold assembly includes a lower portion positioned over a diverter housing of the diverter assembly to at least partially define a diverter chamber of the diverter assembly and an upper portion joined to the lower portion to define a filter cleaning manifold and one or more spray arm channels.
Claims20
A dishwasher appliance defining a vertical direction, the dishwasher appliance comprising:
- a wash tub that defines a wash chamber;
- a sump for collecting wash fluid;
- a wash pump assembly in fluid communication with the sump for circulating the wash fluid;
- a diverter assembly fluidly coupled to the wash pump assembly for selectively directing the wash fluid;
- and
- a hydraulic manifold assembly fluidly coupled to the diverter assembly, the hydraulic manifold assembly comprising:
- a lower portion positioned over a diverter housing of the diverter assembly to at least partially define a diverter chamber of the diverter assembly;
- and
- an upper portion joined to the lower portion to define a filter cleaning manifold and one or more spray arm channels, wherein the upper portion and the lower portion define at least one wash fluid plenum downstream of a diverter chamber.
A hydraulic manifold assembly for a dishwasher appliance, the dishwasher appliance comprising a wash pump assembly for circulating wash fluid and a diverter assembly fluidly coupled to the wash pump assembly for selectively directing the wash fluid, the hydraulic manifold assembly comprising:
- a lower portion positioned over a diverter housing of the diverter assembly to at least partially define a diverter chamber of the diverter assembly;
- an upper portion joined to the lower portion to define a filter cleaning manifold and one or more spray arm channels;
- and
- a diverter gasket overmolded onto the lower portion of the hydraulic manifold assembly for sealing against the diverter housing to define the diverter chamber.
A dishwasher appliance defining a vertical direction, the dishwasher appliance comprising:
- a wash tub that defines a wash chamber;
- a sump for collecting wash fluid;
- a wash pump assembly in fluid communication with the sump for circulating the wash fluid;
- a diverter assembly fluidly coupled to the wash pump assembly for selectively directing the wash fluid;
- and
- a hydraulic manifold assembly fluidly coupled to the diverter assembly, the hydraulic manifold assembly comprising:
- a lower portion positioned over a diverter housing of the diverter assembly to at least partially define a diverter chamber of the diverter assembly;
- and
- an upper portion joined to the lower portion to define a filter cleaning manifold and one or more spray arm channels;
- and
- a cylindrical filter screen positioned within the sump, the cylindrical filter screen defining a filtered region and an unfiltered region, wherein the lower portion of the hydraulic manifold assembly defines one or more vertical spray arms extending along the vertical direction adjacent the cylindrical filter screen, the one or more vertical spray arms defining a plurality of outer ports in fluid communication with the filter cleaning manifold, the plurality of outer ports being positioned and oriented for directing the wash fluid at least partially along a circumferential direction about the cylindrical filter screen.
