Abstract
A dishwasher appliance includes a spray nozzle having a housing defining a spray chamber in fluid communication with a fluid circulation assembly. A diversion element is positioned within the spray chamber and is movable between a lowered position and a raised position where it contacts a discharge orifice. The diversion element defines a plurality of flow paths that are randomly oriented relative to the discharge orifice every time the diversion element is moved into the raised position, such as when the fluid circulation assembly cycles off and then on again.
Claims20
A dishwasher appliance defining a vertical, a lateral, and a transverse direction, the dishwasher appliance comprising:
- a wash tub that defines a wash chamber;
- a wash rack mounted within the wash chamber, the wash rack being configured for receiving articles for washing;
- a fluid circulation assembly for providing a flow of wash fluid for cleaning articles placed within the wash chamber;
- and
- a spray nozzle comprising:
- a housing defining a spray chamber in fluid communication with the fluid circulation assembly, the housing defining a discharge orifice;
- and
- a diversion element positioned within the spray chamber, the diversion element defining a plurality of flow paths and being movable between a lowered position and a raised position, at least one of the plurality of flow paths directing the flow of wash fluid through the discharge orifice when the diversion element is in the raised position,
- wherein the fluid circulation assembly is selectively operated to move the diversion element between the lowered and the raised position, such that the diversion element is randomly oriented each time the fluid circulation assembly urges the flow of wash fluid.
A spray nozzle for a dishwasher appliance, the dishwasher appliance comprising a fluid circulation assembly for selectively urging a flow of wash fluid, the spray nozzle comprising:
- a housing defining a spray chamber in fluid communication with the fluid circulation assembly, the housing defining a discharge orifice;
- and
- a diversion element positioned within the spray chamber, the diversion element being substantially spherical and defining a plurality of flow paths and being movable between a lowered position and a raised position, at least one of the plurality of flow paths directing the flow of wash fluid through the discharge orifice when the diversion element is in the raised position.
A spray nozzle for a dishwasher appliance, the dishwasher appliance comprising a fluid circulation assembly for selectively urging a flow of wash fluid, the spray nozzle comprising:
- a housing defining a spray chamber in fluid communication with the fluid circulation assembly, the housing defining a discharge orifice, wherein the spray chamber defines a chamber width;
- and
- a diversion element positioned within the spray chamber, the diversion element defining a plurality of flow paths and being movable between a lowered position and a raised position, at least one of the plurality of flow paths directing the flow of wash fluid through the discharge orifice when the diversion element is in the raised position, wherein the diversion element defines an element diameter, the chamber width being greater than the element diameter.
