Abstract

A dishwasher includes a modular docking system supporting the docking of one or more spray containers at various locations within a dishwasher. Each spray container includes a container body capable of retaining utensils along with one or more nozzles supplied with fluid by the modular docking system to direct a spray of fluid at utensils retained by the container body.

Claims

1. A dishwasher, comprising:

a wash tub;

a pump configured to recirculate fluid within the wash tub;

a manifold including a fluid inlet in fluid communication with the pump and a plurality of docking ports in fluid communication with the fluid inlet, the plurality of docking ports disposed at a plurality of locations;

a plurality of valves respectively coupled to the plurality of docking ports, each valve configured to seal the respective docking port when the respective docking port is unused; and

a plurality of spray containers, each spray container including;

a container body configured to retain utensils;

one or more nozzles integrated with the spray container and configured to direct a spray of fluid at utensils retained by the container body; and

a connector in fluid communication with the one or more nozzles and configured to removably and mechanically couple with a docking port among the plurality of docking ports, the connector further configured to place the one or more nozzles in fluid communication with the manifold when removably and mechanically coupled with the docking port, wherein each of the plurality of spray containers is configured to be docked in multiple locations among the plurality of locations to customize the dishwasher for different wash loads.

2. The dishwasher of claim 1, further comprising:

a rack disposed in the wash tub and configured to support a plurality of utensils to be washed, wherein the manifold is coupled to the rack; and

a port disposed on a wall of the wash tub and in fluid communication with the pump;

wherein the rack is configured to move between loading and washing positions along a substantially horizontal direction, and wherein the fluid inlet of the manifold is configured to mate with the port disposed on the wall of the wash tub when the rack is moved to the washing position such that the manifold is in fluid communication with the pump when the rack is moved to the washing position.

3. The dishwasher of claim 1, wherein a first spray container among the plurality of spray containers is a spray basket including a bottom wall and one or more side walls defining a perimeter of the container body, and wherein the container body defines one or more compartments for housing utensils.

4. The dishwasher of claim 3, wherein the first spray container is a silverware basket configured to house silverware and/or cutlery.

5. The dishwasher of claim 4, wherein the first spray container includes an interior sprayer disposed within an interior of the container body and inwardly from the side walls defining the perimeter of the container body, wherein the one or more nozzles are disposed on the interior sprayer to direct a spray of fluid at utensils retained within a compartment among the one or more compartments of the container body.

6. The dishwasher of claim 5, wherein the interior sprayer is in fluid communication with the connector of the first spray container and extends along an axis substantially perpendicular to the bottom wall, and wherein the one or more nozzles includes a plurality of nozzles separated from one another along the axis.

7. The dishwasher of claim 6, wherein the first spray container further includes an overhead sprayer disposed above a compartment among the one or more compartments and in fluid communication with the connector of the first spray container, the overhead sprayer configured to direct a spray of fluid into a compartment among the one or more compartments from a higher elevation than the plurality of side walls.

8. The dishwasher of claim 7, wherein the overhead sprayer spins or oscillates in response to fluid flow.

9. The dishwasher of claim 7, wherein the overhead sprayer is integrated into a handle of the first spray container.

10. The dishwasher of claim 3, wherein the first spray container is a drinkware basket configured to house cups, glasses, bottles and/or stemware.

11. The dishwasher of claim 10, wherein the first spray container includes at least one spray member disposed in a compartment among the one or more compartments of the first spray container and configured to direct a spray of fluid onto an interior surface of a drinkware article.

12. The dishwasher of claim 11, wherein the at least one spray member is in fluid communication with the connector of the first spray container and projects upwardly into the drinkware article when the drinkware article is placed upside down in the compartment.

13. The dishwasher of claim 12, wherein the at least one spray member includes a plurality of side nozzles configured to direct a spray of fluid toward a side wall of the drinkware article and one or more end nozzles configured to direct a spray of fluid toward a bottom of the drinkware article.

14. The dishwasher of claim 12, wherein the first spray container further includes an adjustable stemware support configured to support a stem of the drinkware article.

15. The dishwasher of claim 14, wherein the drinkware article is a first drinkware article, and wherein the adjustable stemware support is further configured to additionally support a second drinkware article above the first drinkware article.

16. The dishwasher of claim 14, wherein the adjustable stemware support includes a drinkware support member configured to pivot about a substantially horizontal axis between engaged and unengaged positions, and further configured to move along a substantially vertical axis to adjust an elevation thereof.

17. The dishwasher of claim 3, wherein the first spray container is a cup tree including a plurality of branches, each branch configured to support a drinkware article, and each branch including one or more nozzles in fluid communication with the connector of the first spray container to direct a spray of fluid onto an interior surface of the drinkware article, wherein the plurality of branches extend from a single vertical trunk and are disposed at a plurality of elevations.

18. The dishwasher of claim 1, wherein a first spray container among the plurality of spray containers includes a mechanical coupler configured to mechanically couple with a second docking port without unsealing the second docking port.

19. The dishwasher of claim 1, wherein the manifold further includes a plurality of mechanical supports arranged intermediate of docking ports among the plurality of docking ports, and wherein a first spray container among the plurality of spray containers includes a cooperative mechanical coupler configured to mate with one of the plurality of mechanical supports when the connector of the first spray container mates with one of the plurality of docking ports.

20. The dishwasher of claim 1, wherein the manifold is a first manifold and is supported on a rack, and wherein the rack further includes a second manifold including a second fluid inlet in fluid communication with the pump and a second plurality of docking ports in fluid communication with the second fluid inlet.
