Abstract

A dishwasher appliance and a method for mounting a slide rail within a dishwasher appliance are provided. A rack assembly of the dishwasher appliance includes a bracket with a post. A slide rail is mounted to the bracket, and the slide rail and the bracket are positioned within a wash chamber of the dishwasher appliance. The post extends through the tub, and a sleeve is positioned opposite the bracket on the tub and engages the post. The sleeve hinders retraction of the post through the tub.

First claim

What is claimed is:

1. A dishwasher appliance, comprising:
a tub defining a wash chamber; and
a rack assembly positioned within the wash chamber, the rack assembly comprising
a bracket positioned within the wash chamber of the tub;
a post integrally mounted to the bracket as a continuous element, the post extending through the tub;
a sleeve positioned opposite the bracket on the tub, the sleeve engaging the post such that the sleeve hinders the post from retracting through the tub; and
a slide rail positioned within the wash chamber and mounted to the bracket,
wherein the post comprises a threaded post and the sleeve defines an inner chamber that extends between a first opening and a second opening, the threaded post extending through the tub into the inner chamber of the sleeve at the first opening of the inner chamber, a fastener extending into the inner chamber of the sleeve at the second opening of the inner chamber outside of the wash chamber, the fastener being compressed against the sleeve.

2. The dishwasher appliance of claim 1 , wherein a top portion of the tub defines a curved inner surface, the bracket defining a curved outer surface that is complementary to the curved inner surface of the tub, the bracket positioned within the wash chamber such that the curved outer surface of the bracket is positioned at the curved inner surface of the tub, wherein the threaded post extends from the curved inner surface.

3. The dishwasher appliance of claim 1 , wherein the rack assembly further comprises a gasket extending between the bracket and the tub.

4. The dishwasher appliance of claim 1 , wherein the fastener includes a plate having a width, the width of the plate being greater than a width of the second opening of the inner chamber.

5. The dishwasher appliance of claim 1 , wherein the slide rail comprises a first rail, a second rail and a plurality of bearings, the first rail mounted to the bracket, the plurality of bearings permitting movement of the second rail relative to the first rail.

6. The dishwasher appliance of claim 5 , wherein the rack assembly further comprises a projection, a clip and a wire frame, the projection mounted to the second rail, the clip mounted to the wire frame and defining a vertical slot, the projection received within the vertical slot.

7. The dishwasher appliance of claim 6 , wherein the vertical slot is a first vertical slot, the clip further defining a second vertical slot and a transverse slot that extends between the first and second vertical slots, the projection moveable within the transverse slot between the first and second vertical slots.

8. A method for mounting a slide rail to a tub of a dishwasher appliance, comprising:
providing the tub that defines a wash chamber, a bracket with a post and a sleeve, the post integrally mounted to the bracket as a continuous element, the post comprising a threaded post, and the sleeve defining an inner chamber that extends between a first opening and a second opening;
positioning the bracket within the wash chamber of the tub;
directing the post of the bracket through a hole in a wall of the tub such that the post extends through the tub into the inner chamber of the sleeve at the first opening of the inner chamber;
fastening the sleeve to the post of the bracket; and
fixing a fastener to the post, the fastener extending into the inner chamber of the sleeve at the second opening of the inner chamber outside of the wash chamber, the fastener being compressed against the sleeve.

9. The method of claim 8 , wherein said step of fastening comprises manually rotating the sleeve onto the post of the bracket.

10. The method of claim 8 , wherein said step of fixing comprises turning the fastener with a drill and threading the fastener into the post with the drill.

11. The method of claim 8 , further comprising mounting the bracket to the slide rail prior to said step of positioning.

12. The method of claim 11 , wherein the slide rail is substantially level after said step of fastening.

13. The method of claim 8 , wherein said step of providing farther comprises providing a gasket, wherein said step of positioning comprises positioning the bracket within the wash chamber of the tub such that the gasket is positioned between the tub and the bracket.

14. The method of claim 13 , further comprising drawing the bracket towards the tub such that the gasket compresses between the tub and the bracket.

15. The method of claim 8 , wherein the bracket is a first bracket and the sleeve is a first sleeve, said step of providing further comprising providing a second bracket with a post and a second sleeve, said step of positioning comprising positioning the first and second bracket within the wash chamber of the tub, said step of directing comprising directing the post of the first bracket through a first hole defined by the tub and the post of the second bracket through a second hole defined by the tub, said step of fastening comprises fastening the first sleeve onto the post of the first bracket and the second sleeve onto the post of the second bracket.

16. A dishwasher appliance, comprising
a tub defining a wash chamber;
a wire frame positioned within the wash chamber;
a slide rail mounted to the tub;
means for coupling the wire frame to the slide rail;
a bracket mounted to the slide rail within the wash chamber of the tub;
a post integrally mounted to the bracket as a continuous element, the post extending through the tube; and
a sleeve positioned opposite the bracket on the tub, the sleeve engaging the post such that the sleeve hinders the post from retracting through the tub,
wherein the post comprises a threaded post and the sleeve defines an inner chamber that extends between a first opening and a second opening, the threaded post extending through the tub into the inner chamber of the sleeve at the first opening of the inner chamber, a fastener extending into the inner chamber of the sleeve at the second opening of the inner chamber outside of the wash chamber, the fastener being compressed against the sleeve.

17. The dishwasher appliance of claim 16 , wherein the means for coupling comprises a projection and a clip, the projection mounted to the slide rail, the clip mounted to the wire frame and defining a first vertical slot, a second vertical slot and a transverse slot that extends between the first and second vertical slots, the projection moveable within the transverse slot between the first and second vertical slots.

18. The dishwasher appliance of claim 16 , wherein the means for coupling comprises a plurality of hooks and a plurality of clips, the plurality of clips mounted to the slide rail, each clip of the plurality of clips defining an opening, the plurality of hooks mounted to the wire frame, each hook of the plurality of hooks positioned within a respective opening of the plurality of clips.
