Fluid circulation arrangement for providing an intensified wash effect in a dishwasher and an associated method
First Claim
1. A dishwasher comprising:
- a tub;
a rack configured to be positioned within the tub, wherein the rack defines a bottom of the rack and at least one sidewall that extends upwardly from the bottom of the rack, the rack adapted to receive dishware therein;
a dishwashing fluid supply channel configured to supply a dishwashing fluid;
a spray arm positioned below the rack, wherein the spray arm is configured to receive the dishwashing fluid and to dispense the dishwashing fluid; and
a spray assembly directly coupled to the sidewall of the rack, the spray assembly comprising at least one nozzle member adapted to receive the dishwashing fluid from the dishwashing fluid supply channel and to dispense the dishwashing fluid therefrom into an intensified wash zone, the spray assembly comprising a manifold coupled to the sidewall and a plurality of nozzle members coupled thereto, wherein the manifold is positioned adjacent to the sidewall such that the nozzle members extend at least partially through the sidewall; and
wherein the dishwashing fluid dispensed from the spray arm is incident on the intensified wash zone from a different direction than the dishwashing fluid dispensed from the spray assembly.

Abstract
According to embodiments of the present invention, a dishwasher may provide an intensified wash effect. The dishwasher may include a rack defining a bottom and a sidewall, wherein the rack is adapted to receive dishware therein. A dishwashing fluid supply channel may be configured to supply dishwashing fluid to a spray assembly. The spray assembly may comprise at least one nozzle member. Thereby, the spray assembly may be adapted to receive the dishwashing fluid from the dishwashing fluid supply channel and to dispense the dishwashing fluid therethrough. The spray assembly may be coupled to the sidewall of the rack. Further, the nozzle member may be attached to an arm which is moveable between at least a first position wherein the arm is adjacent the sidewall of the rack and a second position wherein the arm is adjacent the bottom of the rack.

22. A dishwasher comprising:
-
a tub; a rack configured to be positioned within the tub, wherein the rack defines a bottom of the rack and at least one sidewall that extends upwardly from the bottom of the rack, the rack adapted to receive dishware therein; a dishwashing fluid supply channel configured to supply a dishwashing fluid; a spray arm positioned below the rack, wherein the spray arm is configured to receive the dishwashing fluid and to dispense the dishwashing fluid; and a spray assembly directly coupled to the sidewall of the rack, the spray assembly comprising at least one nozzle member adapted to receive dishwashing fluid from the dishwashing fluid supply channel and to dispense the dishwashing fluid therefrom into an intensified wash zone, wherein the at least one spray arm defines a spray arm fluid connector configured to couple the at least one spray arm to the dishwashing fluid supply channel to provide fluid communication therebetween, wherein the at least one spray arm is configured to direct dishwashing fluid into the tub, wherein the spray assembly further comprises a spray assembly fluid connector configured to couple the spray assembly to the dishwashing fluid supply channel so as to provide fluid communication therebetween, and wherein the spray assembly fluid connector is spaced apart from the spray arm fluid connector such that there is no direct fluid communication between the at least one spray arm and the spray assembly and wherein the dishwashing fluid dispensed from the spray arm is incident on the intensified wash zone from a different direction than the dishwashing fluid dispensed from the spray assembly.
