Abstract
An automatic dishwasher with a treating chamber, at least one dish holder, and a sprayer. The sprayer can be coupled to the dish holder and include a set of fan spray nozzles or a set of jet nozzles. The set of fan spray nozzles or the set of jet nozzles fluidly connect the sprayer and treating chamber. One or more angles in which fluid flows from the set of fan spray nozzles or the set of jet nozzles into the treating chamber can be adjusted.
Claims36
A dishwasher for treating dishes according to an automatic cycle of operation, the dishwasher comprising:
- a tub at least partially defining a treating chamber with an access opening;
- a closure mounted for relative movement with the tub to selectively open/close the access opening;
- at least one dish holder located within the treating chamber;
- a sprayer emitting liquid into the treating chamber and having a manifold having a hollow interior through which liquid flows to define a flow direction;
- a recirculation circuit fluidly coupling the treating chamber to the sprayer to recirculate liquid from the treating chamber to the hollow interior of the sprayer;
- and
- a set of fan spray nozzles provided on the manifold with at least some of the fan spray nozzles in the set comprising a slot with a corresponding rib, upstream of the slot, the rib having a height controlling an angle at which liquid is emitted from the slot into the treating chamber.
