Apparatus for deflecting a spray of wash liquid to a desired location in a cleaning appliance

1. A cleaning appliance comprising:

a wash chamber for holding items to be washed;

a wash liquid dispenser having an outlet for emitting wash liquid; and

at least one deflector located to deflect the wash liquid emitted from the outlet into the wash chamber, and comprising:

an outer surface; and

a deflecting surface opposite the outer surface comprising:

a laterally planar first section in axially opposing relation to the outlet; and

a laterally planar second section below the outlet and which terminates in a rounded tip having a tear-drop shape;

wherein the first section is oriented at a first angle and the second section is oriented at a second angle that is different than the first angle, and an intersection of the first and second sections forms an obtuse angle; and

wherein the outer and deflecting surfaces merge toward each other in a direction away from the rounded tip to define the tear-drop shape.

2. The cleaning appliance according to claim 1 wherein the second section is oriented at a steeper angle than the first section.

3. The cleaning appliance according to claim 1 wherein the at least one deflector comprises multiple deflectors disposed around the wash chamber.

4. The cleaning appliance according to claim 1 wherein the first section and the second section are joined by a transition section which is configured to maintain liquid adhesion along the deflecting surface.

5. The cleaning appliance according to claim 1 wherein the deflecting surface comprises an uninterrupted deflecting surface.

6. The cleaning appliance according to claim 1 wherein the deflecting surface comprises a laterally uninterrupted deflecting surface.

7. The cleaning appliance according to claim 1 wherein wash liquid emitted at a first velocity flows along the deflecting surface and separates from the deflector at the tip in a fan-like pattern, and wash liquid emitted at a second velocity, less than the first velocity, flows along the deflecting surface around the tip wherein it separates from the deflector in a fountain-like pattern.

8. The cleaning appliance according to claim 7 wherein the fan-like pattern comprises wash liquid moving downwardly from the detecting surface.

9. The cleaning appliance according to claim 7 wherein the fountain-like pattern comprises wash liquid moving upwardly and outwardly from the outer surface.

10. The cleaning appliance according to claim 1 and further comprising a tub for holding wash liquid and a drum located within the tub and defining the wash chamber.

11. The cleaning appliance according to claim 10 wherein the drum rotates about a vertical axis of rotation.

12. The cleaning appliance according to claim 10 and further comprising a tub ring carried by the tub and defining an opening into the drum and the at least one deflector is provided on the tub ring.

13. The cleaning appliance according to claim 12 wherein the at least one deflector is formed in the tub ring.

14. The cleaning appliance according to claim 12 wherein the wash liquid dispenser comprises a header with at least one orifice aligned with the at least one deflector and defining the outlet.

15. The cleaning appliance according to claim 1 , wherein the at least one deflector comprises a shape wherein wash liquid emitted at a first velocity separates from the deflector at a first location and wash liquid emitted at a second velocity, less than the first velocity, separates from the deflector at a second location.

16. The cleaning appliance according to claim 15 wherein the first location comprises the deflecting surface of the at least one deflector.

17. The cleaning appliance according to claim 15 wherein the second location comprises the outer surface of the at least one deflector.

18. A cleaning appliance comprising:

a tub for holding wash liquid;

a drum located within the tub and defining a wash chamber for holding items to be washed;

a wash liquid dispenser having an outlet for emitting wash liquid; and

at least one deflector located to deflect the wash liquid emitted from the outlet into the wash chamber, and comprising:

an outer surface; and

a deflecting surface opposite the outer surface comprising:

a first angled section in axially opposing relation to the outlet; and

a second angled section below the outlet and which terminates in a rounded tip having a tear-drop shape;

wherein the first angled section is oriented at a first angle and the second angled section is oriented at a second angle that is steeper than the first angle, and an intersection of the first and second angled sections forms an obtuse angle; and

wherein the outer and deflecting surfaces merge toward each other in a direction away from the rounded tip to define the tear-drop shape.

19. The cleaning appliance according to claim 18 , wherein the at least one deflector comprises a shape to provide at least two distinct flow paths in response to the velocity of the emitted wash liquid, with a first flow path projecting downwardly from the deflector and a second flow path projecting forwardly from the deflector.

20. The cleaning appliance according to claim 19 wherein the shape comprises the tip having a geometry that provides at least one of the at least two distinct flow paths.

21. The cleaning appliance according to claim 19 wherein the first flow path generates a fan-like pattern.

22. The cleaning appliance according to claim 19 wherein the second flow path generates a fountain-like pattern.

23. The cleaning appliance according to claim 18 wherein the drum rotates about a vertical axis of rotation.

24. The cleaning appliance according to claim 18 and further comprising a tub ring carried by the tub and defining an opening into the drum and the at least one deflector is carried by the tub ring.

25. The cleaning appliance according to claim 24 wherein the at least one deflector is formed in the tub ring.

26. The cleaning appliance according to claim 24 wherein the wash liquid dispenser comprises a header with at least one orifice aligned with the at least one deflector and defining the outlet.

27. The cleaning appliance according to claim 18 wherein the at least one deflector comprises multiple deflectors disposed around the wash chamber.
