Abstract

A laundry appliance includes a drum that is rotationally operable within a wash tub. A chemistry receptacle is located proximate the drum. A chemistry dispensing module is coupled to the chemistry receptacle and has a prewash portion and a main wash portion. A first fluid inlet is coupled with the prewash portion and a second fluid inlet is coupled to the main wash portion. An outlet extends from the chemistry dispensing module to a laundry treating chamber. A prewash nozzle is coupled to the first fluid inlet and the prewash portion. The prewash nozzle includes an elongated arcuate body that follows a curvature of the prewash portion and defines a cyclonic flow path from the prewash nozzle to the outlet.

Claims (18)

1. A laundry appliance comprising:

a drum that is rotationally operable within a wash tub;

a chemistry receptacle located proximate the drum;

a chemistry dispensing module coupled to the chemistry receptacle and having a prewash portion and a main wash portion;

a first fluid inlet coupled with the prewash portion and a second fluid inlet coupled to the main wash portion;

an outlet that extends from the chemistry dispensing module to a laundry treating chamber; and

a prewash nozzle coupled to the first fluid inlet and the prewash portion, wherein the prewash nozzle includes an elongated arcuate body that follows a curvature of the prewash portion and defines a cyclonic flow path from the prewash nozzle to the outlet.

2. The laundry appliance of claim 1 , wherein the main wash portion is positioned at least partially above the prewash portion.

3. The laundry appliance of claim 2 , wherein a fluid moving through the prewash portion does not substantially enter into the main wash portion.

4. The laundry appliance of claim 1 , wherein the elongated arcuate body includes a substantially continuous arcuate wall that extends from the first fluid inlet to an open bottom of the prewash nozzle.

5. The laundry appliance of claim 4 , wherein the prewash nozzle and the prewash portion cooperate to define the cyclonic flow path as a laminar flow path at least from the open bottom of the prewash nozzle and to the outlet.

6. The laundry appliance of claim 1 , wherein the prewash nozzle is slidably engaged with the first fluid inlet.

7. The laundry appliance of claim 6 , wherein the prewash nozzle is an after-market nozzle that is configured to replace a manufacturer installed nozzle.

8. The laundry appliance of claim 1 , further comprising:

a main wash nozzle slidably coupled with the second fluid inlet, wherein the main wash nozzle includes an angled deflector, the angled deflector adapted to redirect a main wash fluid through the main wash portion and to the outlet.

9. The laundry appliance of claim 1 , wherein the prewash portion is laterally offset from the main wash portion.

10. The laundry appliance of claim 9 , wherein the main wash portion is at least partially located between the outlet and the prewash portion.

11. The laundry appliance of claim 1 , wherein the prewash portion includes a substantially rounded end, and wherein the prewash nozzle is seated within the rounded end.
