Abstract

A dishwashing appliance having a static jet assembly is provided herein. The dishwashing appliance may include a tub defining a wash chamber, a pump, and a spray assembly. The pump may be configured to deliver a wash fluid into the wash chamber. The spray assembly may be housed within the wash chamber of the tub in fluid communication with the pump to receive wash fluid therefrom. The static jet assembly may be disposed within the wash chamber and include a static body. The static body may extend about an exterior hole. The static body may define an interior passage and a jet aperture in fluid communication with the pump. The jet aperture may be defined in fluid communication between the interior passage and the wash chamber.

Claims

1. A dishwashing appliance comprising:

a tub defining a wash chamber;

a pump configured to deliver a wash fluid into the wash chamber;

a spray assembly housed within the wash chamber of the tub in fluid communication with the pump to receive wash fluid therefrom; and

a static jet assembly disposed within the wash chamber, the static jet assembly comprising a static body extending about an exterior hole such that the static body defines an enclosed perimeter shape of the exterior hole, the static body defining an interior passage and a jet aperture in fluid communication with the pump, the jet aperture being defined in fluid communication between the interior passage and the wash chamber, wherein the exterior hole defines a void through which fluid may pass, independent of the jet aperture and the pump.

2. The dishwashing appliance of claim 1, wherein the exterior hole defines a central axis parallel to the exterior hole and radially inward from the static body, and wherein the jet aperture is defined at a non-parallel angle directed toward the central axis.

3. The dishwashing appliance of claim 1, further comprising:

a basket disposed within the wash chamber, the basket defining a plurality of fluid slots, wherein the jet aperture is directed toward the basket.

4. The dishwashing appliance of claim 3, wherein the static body further defines a plurality of jet apertures, and wherein each of the plurality of jet apertures is aligned in fluid communication with a discrete slot of the plurality of fluid slots.

5. The dishwashing appliance of claim 3, wherein the static body includes an upper face and a support ridge, wherein the support ridge extends in a vertical direction from the upper face in engagement with a bottom portion of the basket, and wherein the upper face is spaced apart from the bottom portion of the basket.

6. The dishwashing appliance of claim 1, further comprising;

a fluid conduit fixed to the tub within the wash chamber, the fluid conduit extending in fluid communication between the pump and the interior passage.

7. The dishwashing appliance of claim 6, wherein the static body defines an inlet separably connected to the fluid conduit.

8. The dishwashing appliance of claim 7, wherein the fluid conduit includes a resilient bellow extending toward the inlet in fluid communication therewith.

9. The dishwashing appliance of claim 1, further comprising:

a rack assembly slidably disposed within the wash chamber above the spray assembly, wherein the static body is mounted to the rack assembly.

10. The dishwashing appliance of claim 9, wherein the jet aperture is defined at a non-parallel angle relative to a vertical direction.

11. The dishwashing appliance of claim 9, further comprising:

a basket disposed within the wash chamber, the basket defining a plurality of fluid slots, wherein the jet aperture is directed toward the basket.

12. The dishwashing appliance of claim 11, wherein the static body includes an upper face and a support ridge extending in a vertical direction from the upper face in engagement with a bottom portion of the basket, wherein the upper face is spaced apart from the bottom portion of the basket.

13. The dishwashing appliance of claim 9, further comprising;

a fluid conduit fixed to the tub within the wash chamber, the fluid conduit extending in fluid communication between the pump and the interior passage, wherein the static body defines an inlet separably connected to the fluid conduit.

14. The dishwashing appliance of claim 13, wherein the fluid conduit includes a resilient bellow extending toward the inlet in fluid communication therewith.

15. The dishwashing appliance of claim 9, wherein the spray assembly is a lower spray arm assembly disposed below the static body.

16. The dishwashing appliance of claim 15, wherein the rack assembly is a lower rack assembly disposed above the lower spray arm assembly, and wherein the dishwashing appliance further comprises:

an upper rack assembly disposed above the lower rack assembly;

an intermediate spray arm assembly disposed between the upper rack assembly and the lower rack assembly; and

an upper spray assembly disposed above the upper rack assembly.

17. The dishwashing appliance of claim 9, wherein the rack assembly is an upper rack assembly, and wherein the dishwashing appliance further comprises a lower rack assembly disposed beneath the upper rack assembly to receive a wash fluid directed from the jet aperture.

18. The dishwashing appliance of claim 9, wherein the rack assembly is a lower rack assembly defining a wash compartment to receive a wash fluid directed from the jet aperture, and wherein the dishwashing appliance further comprises an upper rack assembly disposed above the lower rack assembly.

19. The dishwashing appliance of claim 1, wherein the spray assembly is a lower spray arm assembly disposed below the static body.
