## Abstract

A dishwasher appliance and a spray assembly for the same are provided. The spray assembly includes a spray body and features for moving the spray body within a wash chamber of the dishwasher appliance. Wash fluid coverage within the wash chamber can be improved by moving the spray body within the wash chamber.

## Claims

### Claim 1

A dishwasher appliance, comprising:
a tub that defines a wash chamber;
a rack assembly slidably positioned within the wash chamber of said tub and configured for receipt of articles for washing;
a spray assembly mounted within the wash chamber of said tub and configured for directing a spray of wash fluid towards said rack assembly, said spray assembly defining a lateral direction, said spray assembly comprising
a spray body;
a pair of links, each link of said pair of links rotatably mounted to said tub and said spray body;
a crank configured for rotation about an axis of rotation; and
a coupler rotatably mounted to one of said pair of links and said crank such that said coupler extends between and connects said crank and the one of said pair of links;
wherein said spray body moves along the lateral direction when said crank rotates about the axis of rotation.

### Claim 2 (depends on 1)

The dishwasher appliance of claim 1, wherein said spray assembly defines a transverse direction that is perpendicular to the lateral direction, each link of said pair of links extending between first end portion and a second end portion, the first end portions of said pair of links rotatably mounted to said tub at opposite, transverse sides of the wash chamber of said tub.

### Claim 3 (depends on 1)

The dishwasher appliance of claim 1, wherein the second end portions of said pair of links are rotatably mounted to said spray body at opposite, lateral side portions of said spray body.

### Claim 4 (depends on 1)

The dishwasher appliance of claim 1, wherein the first end portions of said pair of links are spaced apart from each other along the transverse direction.

### Claim 5 (depends on 1)

The dishwasher appliance of claim 1, wherein the second end portions of said pair of links are spaced apart from each other along the lateral direction.

### Claim 6 (depends on 1)

The dishwasher appliance of claim 1, wherein said spray assembly defines a transverse direction that is perpendicular to the lateral direction, the links of said pair of links being spaced apart from each other along the transverse direction.

### Claim 7 (depends on 1)

The dishwasher appliance of claim 1, wherein said spray assembly further comprises a motor in mechanical communication with said crank, said motor configured for rotating said crank about the axis of rotation.

### Claim 8 (depends on 1)

The dishwasher appliance of claim 1, wherein said spray assembly further comprises a rail mounted to said tub and extending along the lateral direction, said spray body slidably mounted to said rail.

### Claim 9 (depends on 1)

The dishwasher appliance of claim 1, wherein said pair of links includes a water link that is configured for supplying wash fluid to said spray body, said spray body defining a plurality of outlets for directing wash fluid towards said rack assembly.

### Claim 10 (depends on 1)

The dishwasher appliance of claim 1, wherein said spray body includes a first spray arm and a second spray arm spaced apart from each other along the lateral direction.

### Claim 11 (depends on 1)

The dishwasher appliance of claim 1, wherein the wash chamber of said tub extends between a top portion and a bottom portion, said spray assembly positioned at the top portion of the chamber and also positioned above said rack assembly.

### Claim 12

A spray assembly for a dishwasher appliance, the spray assembly defining a lateral direction and a transverse direction, the spray assembly comprising:
a spray body having a first lateral side portion and a second lateral side portion spaced apart from each other along the lateral direction, said spray body also having a first transverse side portion and a second transverse side portion spaced apart from each other along the transverse direction;
a link positioned proximate the second transverse side portion of said spray body and rotatably mounted to said spray body at the second lateral side portion of said spray body;
a rocker positioned proximate the first transverse side portion of said spray body and rotatably mounted to said spray body at the first lateral side portion of said spray body;
a crank configured for rotation about an axis of rotation; and
a coupler rotatably mounted to said rocker and said crank such that said coupler extends between and connects said crank and said rocker;
wherein said spray body moves along the lateral direction when said crank rotates about the axis of rotation.

### Claim 13 (depends on 12)

The spray assembly of claim 12, further comprising a motor in mechanical communication with said crank, said motor configured for rotating said crank about the axis of rotation.

### Claim 14 (depends on 12)

The spray assembly of claim 12, further comprising a rail that extends along the lateral direction, said spray body slidably mounted to said rail.

### Claim 15 (depends on 12)

The spray assembly of claim 12, wherein said link defines a passage, the passage of said link configured for directing a flow of wash fluid into said spray body, said spray body defining a plurality of outlets for directing the flow of wash fluid out of said spray body.

### Claim 16 (depends on 12)

The spray assembly of claim 12, wherein said spray body includes a first spray arm and a second spray arm spaced apart from each other along the lateral direction.

### Claim 17

A dishwasher appliance, comprising:
a tub that defines a wash chamber;
a rack assembly slidably mounted within the wash chamber of said tub and configured for receipt of articles for washing;
a spray assembly mounted within the wash chamber of said tub, said spray assembly defining a lateral direction, said spray assembly comprising
a spray body configured for directing a spray of wash fluid towards said rack assembly; and
means for moving said spray body along the lateral direction.

### Claim 18 (depends on 16)

The dishwasher appliance of claim 16, wherein the wash chamber of said tub extends between a front portion and a back portion along the lateral direction, said means for moving further comprising means for moving said spray body between the front portion of the wash chamber and the back portion of the wash chamber along the lateral direction.

### Claim 19 (depends on 16)

The dishwasher appliance of claim 16, wherein the wash chamber of said tub extends between a left side portion and a right side portion along the lateral direction, said means for moving further comprising means for moving said spray body between the left side portion of the wash chamber and the right side portion of the wash chamber along the lateral direction.

### Claim 20 (depends on 16)

The dishwasher appliance of claim 16, wherein the wash chamber of said tub extends between a top portion and a bottom portion, said spray assembly positioned at the top portion of the chamber and also positioned above said rack assembly.
