Abstract

A dishwasher for treating dishes according to a cycle of operation, the dishwasher having a tub at least partially defining a treating chamber, a dish rack having a first wash zone and a second wash zone, and a spray tube having at least one set of nozzles and rotatable between a first position and a second position.

Claims (26)

1. A dishwasher for treating dishes according to a cycle of operation, the dishwasher comprising:

a tub at least partially defining a treating chamber;

a dish rack having a first wash zone and a second wash zone, the dish rack defined by at least a first set of wires and a second set of wires, separate from the first set of wires, together defining a frame including an upper rim and the dish rack having at least one section defined by the second set of wires in the second wash zone movable between a deployed position, wherein the at least one section is spaced from the upper rim to define a depth of the at least one section from the upper rim, and a stowed position, wherein the at least one section is located proximate the upper rim; and

a spray tube having at least one set of nozzles and rotatable between a first position, wherein the at least one set of nozzles is oriented toward the at least one section when the at least one section is in the deployed position, and a second position, wherein the at least one set of nozzles is oriented toward the first wash zone.

2. The dishwasher of claim 1 wherein the spray tube is fluidly coupled to a water supply and the at least one nozzle faces the second wash zone when in the first position.

3. The dishwasher of claim 2 wherein the spray tube is closed to a water supply when in the second position facing the first wash zone.

4. The dishwasher of claim 2 wherein the spray tube is open to a water supply and the at least one nozzle faces the first wash zone when in the second position.

5. The dishwasher of claim 1 further comprising a second dish rack, below the first rack, received within the treating chamber, and having a least a portion with a seat for supporting dishes.

6. The dishwasher of claim 5 wherein, in the deployed position, a lowest point of the at least one section defines the depth of the at least one section and defines a first height with the seat, and, in the stowed position, the lowest point of the at least one section defines a second height with the seat, the second height being greater than the first height and the depth of the at least one section from the upper rim being deeper in the deployed position than in the stowed position.

7. The dishwasher of claim 1 wherein the first set of wires is stationary.

8. The dishwasher of claim 7 further comprising a third set of wires that is stationary and wherein the second set of wires is disposed between the first and third set of wires.

9. The dishwasher of claim 8 further comprising a pivot connection for connecting sequential wires in the second set of wires.

10. The dishwasher of claim 9 wherein the pivot connection defines a pivot axis about which the second set of wires rotates.

11. The dishwasher of claim 10 wherein the pivot connection defines a meeting edge between the second set of wires and the third set of wires.

12. A dishwasher for treating dishes according to a cycle of operation, the dishwasher comprising:

a tub at least partially defining a treating chamber;

a dish rack having a first wash zone and a second wash zone, the dish rack defined by a wire frame including an upper rim and a seat for supporting dishes; the wire frame of the second wash zone being pivotably movable between a deployed position, wherein a distance between the seat and the upper rim defines a first depth, and a stowed position, wherein the distance between the seat and the upper rim defines a second depth; the first depth being bigger than the second depth; and

a spray tube having at least one set of nozzles and rotatable between a first position, wherein the at least one set of nozzles is oriented toward the second wash zone when the second wash zone is in the deployed position, and a second position, wherein the at least one set of nozzles is oriented toward the first wash zone.

13. The dishwasher of claim 12 wherein the spray tube is fluidly coupled to a water supply and the at least one nozzle faces the second wash zone when in the first position.

14. The dishwasher of claim 13 wherein the spray tube is closed to a water supply when in the second position facing the first wash zone.

15. The dishwasher of claim 13 wherein the spray tube is open to a water supply and the at least one nozzle faces the first wash zone when in the second position.

16. The dishwasher of claim 12 further comprising a second dish rack, below the first rack, received within the treating chamber, and having a least a portion with a seat for supporting dishes.

17. The dishwasher of claim 12 wherein the dish rack is defined by at least a first set of wires and a second set of wires, separate from the first set of wires, the second set of wires at least partially defining the second wash zone.

18. The dishwasher of claim 12 wherein the first set of wires is stationary.

19. The dishwasher of claim 18 further comprising a third set of wires that is stationary and wherein the second set of wires is disposed between the first and third set of wires.

20. The dishwasher of claim 19 wherein the pivot connection defines a pivot axis about which the second set of wires rotates.
