Abstract:
Adapters and spray arm assemblies for dishwasher appliances are provided. An adapter defines an axial direction, a radial direction, and a circumferential direction. The adapter includes a base unit. The base unit includes an inlet housing defining an inlet annulus. The base unit further includes a first conduit extending from the inlet housing and comprising a passage defined between an inlet and an outlet. The base unit further includes a second conduit extending from the inlet housing and comprising a passage defined between an inlet and an outlet. The entire passage of the first conduit and the entire passage of the second conduit each extend at an angle to the axial direction of less than or equal to 60 degrees.
Abstract:
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.
Abstract:
A diverter for a dishwasher appliance that can be used to provide more options for directing fluid among various spray arms or spray devices in a dishwasher appliance. The diverter can be used e.g., to select between fluid delivery to both the upper and lower spray arm assemblies or to both the upper and middle spray arm assemblies.

Abstract:
Spray arm assemblies for dishwasher appliances are provided. A spray arm assembly includes a first spray arm. The first spray arm includes an arm member, the arm member defining an interior and a plurality of apertures in fluid communication with the interior. The arm member further extends along and is rotatable about a longitudinal axis. The spray arm assembly further includes a central housing defining and rotatable about a central axis, the central axis generally perpendicular to the longitudinal axis. In some embodiments, the spray arm assembly further includes a bevel drive assembly disposed within the central housing. The bevel drive assembly is configured to rotate the arm member about the longitudinal axis when the central housing rotates about the central axis. The bevel drive assembly includes a drive member, an axle member, and an idler member, the axle member mounted to the arm member.
Abstract:
A filter assembly for a dishwasher appliance is provided including a first filter, a second filter, and a backflow device. The backflow device is positioned within the second filter and movably attached to the second filter, such that backflow device is movable between an open position and a closed position. When in the closed position, the backflow device prevents a flow of fluid through an inlet of the second filter.
Abstract:
Bottle washer assemblies for dishwasher appliances are provided. A bottle washer assembly includes a main conduit defining a main passage for flowing wash fluid therethrough. The bottle washer assembly further includes a spray tine, the spray tine including a conduit defining a passage for flowing wash fluid therethrough. The passage is in selective fluid communication with the main passage. The conduit is movable between a first position wherein wash fluid flow into the passage is permitted and a second position wherein wash fluid flow into the passage is restricted relative to the wash fluid flow in the first position.

Bottle washer assemblies for dishwasher appliances are provided. A bottle washer assembly includes a main conduit defining a main passage for flowing wash fluid therethrough, and a tine base connected to the main conduit, the tine base defining a base passage in fluid communication with the main passage for flowing wash fluid from the main passage therethrough. The bottle washer assembly further includes a check valve disposed within the base passage, the check valve movable between an open position and a closed position, wherein in the open position the check valve permits wash fluid flow therepast and in the closed position the check valve prevents wash fluid flow therepast. The bottle washer assembly further includes a spray tine, the spray tine comprising a conduit defining a passage for flowing wash fluid therethrough, the spray tine removably connectable to the tine base.
