Abstract

A dishwasher includes a compartment in the form of a drawer or pull-out treating chamber slidably mounted in a chassis is provided with one or more liquid supply and draining conduits for supplying and draining liquid to and from the treating chamber.

First claim

What is claimed is:

1. A dishwasher comprising:
a chassis defining an interior with an open face;
a first fluid coupling located within the interior;
a drawer slidably mounted to the chassis for slidable movement through the open face and at least partially defining a treating chamber with a second fluid coupling; and
a fluid conduit extending between the first fluid coupling and the second fluid coupling, comprising:
a telescoping fluid line having multiple, telescopically connected segments, with a first segment fluidly coupled to the first fluid coupling and a second segment fluidly connected to the second fluid coupling; and
a bellows comprising multiple pleats and extending between the first fluid coupling and the second fluid coupling, encompassing the telescoping fluid line, and configured to direct liquid escaping from the telescoping fluid line into a space between the telescoping fluid line and the bellows and the bellows is configured such that the escaped liquid is drainable through the first fluid coupling and the second fluid coupling; and

wherein as the drawer is slid from a wash position, where the treating chamber is located within the interior, to a loading position, where at least a portion of the treating chamber is exterior of the chassis, the fluid conduit moves from a contracted position to an extended position to extend the segments relative to each other and expand the pleats of the bellows.

2. The dishwasher of claim 1 wherein the first fluid coupling comprises one of a water inlet from a household water supply, a pump outlet, a drain outlet to a household drain, or a pump inlet.

3. The dishwasher of claim 2 further comprising one of a recirculation pump or a wash pump, with the pump inlet being provided on the one of the recirculation pump or the wash pump.

4. The dishwasher of claim 3 wherein at least one of the recirculation pump or the wash pump does not move with the drawer as the drawer is slid from the wash position to the load position.

5. The dishwasher of claim 2 wherein the second fluid coupling comprises one of a treating chamber inlet or a treating chamber outlet.

6. The dishwasher of claim 5 wherein the treating chamber inlet is coupled with a sprayer mounted within the treating chamber.

7. The dishwasher of claim 5 wherein the treating chamber outlet comprises a drain outlet in the treating chamber.

8. The dishwasher of claim 1 wherein the first and second fluid couplings receive the corresponding segment.

9. The dishwasher of claim 8 wherein the bellows circumscribes the first and second fluid couplings.

10. The dishwasher of claim 9 further comprising at least one clamp compressing the bellows about at least one of the first and second fluid couplings.

11. The dishwasher of claim 1 wherein the drawer further comprises a tub and the tub at least partially defines the treating chamber.

12. A dishwasher comprising:
a chassis defining an interior with an open face;
a first fluid coupling located within the interior;
a drawer having a bottom wall and slidably mounted to the chassis for slidable movement through the open face and at least partially defining a treating chamber;
a tub outlet fluidly coupled with the bottom wall of the drawer;
a pump system having a pump outlet fluidly coupled to an inlet of the treating chamber and having a pump inlet fluidly coupled to the tub outlet; and
a fluid conduit extending between the tub outlet and the pump inlet, comprising:
a telescoping fluid line having multiple, telescopically connected segments, with a first segment fluidly coupled to the tub outlet and a second segment fluidly connected to the pump inlet; and
a bellows comprising multiple pleats and extending between the tub outlet and the pump inlet, encompassing the telescoping fluid line, and configured to direct liquid escaping from the telescoping fluid line into a space between the telescoping fluid line and the bellows and the bellows is configured such that the escaped liquid is drainable through the tub outlet and the pump inlet; and

wherein as the drawer is slid from a wash position, where the treating chamber is located within the interior, to a loading position, where at least a portion of the treating chamber is exterior of the chassis, the fluid conduit moves from a contracted position to an extended position to extend the segments relative to each other and expand the pleats of the bellows.
