Abstract

A dispenser for a dishwasher having a wash tub includes a fluid reservoir to hold a treating chemistry, a lid operatively mounted to the fluid reservoir, and configured to move between an open position and a closed position, and a hydraulic actuator fluidly coupled to a fluid source and configured to initiate movement of the lid between its closed and the open positions in response to fluid pressure applied to the actuator by the fluid source. The dispenser is configured to be mounted at more than one location in the wash tub.

First claim

What is claimed is:

1. A dispenser for a dishwasher having a wash tub, the dispenser comprising:
a fluid reservoir to hold a treating chemistry;
a lid operatively mounted to the fluid reservoir, and configured to move between an open position and a closed position; and
a hydraulic actuator configured to be fluidly coupled to a fluid source external to the wash tub, and configured to initiate movement of the lid between the closed and the opened positions in response to fluid pressure applied to the hydraulic actuator by the fluid source external to the wash tub; and
wherein the dispenser is configured to be mounted at more than one location in the wash tub.

2. The dispenser of claim 1 , wherein the wash tub has a treating chamber and the dispenser is configured to be mounted at more than one location in the treating chamber.

3. The dispenser of claim 2 , wherein the treating chamber has a lower rack, an upper rack and a top, and the dispenser is configured to be mounted at any one of the lower rack, the upper rack or the top.

4. The dispenser of claim 3 , further comprising a dispenser supply tube for coupling the dispenser to one of a recirculation pump or to at least one manifold tube for transporting liquid to a spray manifold, a mid-level rotatable sprayer, or an upper sprayer depending on the location of the dispenser in the treating chamber.

5. The dispenser of claim 1 , wherein the wash tub has a lower rack, an upper rack and a top, and the dispenser is configured to be mounted at any one of the lower rack, the upper rack or the top.

6. The dispenser of claim 1 , further comprising a dispenser supply tube for coupling the dispenser to one of a recirculation pump or to at least one manifold tube for transporting liquid to a spray manifold, a mid-level rotatable sprayer, or an upper sprayer depending on the location of the dispenser in the wash tub.

7. A dishwasher configured to execute at least one automatic cycle of operation for treating dishes, the dishwasher comprising:
a tub at least partially defining a treating chamber with an open face for receiving dishes for treatment;
a moveably mounted door movable between an opened position for providing access to the treating chamber and a closed position for selectively closing the open face of the treating chamber during the automatic cycle of operation; and
a dispenser selectively disposed within the tub at any one of a plurality of locations in the tub and comprises a fluid reservoir to hold a treating chemistry, a lid operatively mounted to the fluid reservoir and configured to selectively close the fluid reservoir, and a hydraulic actuator fluidly coupled to a fluid source external to the tub and configured to selectively open the lid in response to fluid pressure applied to the hydraulic actuator by the fluid source during the automatic cycle of operation.

8. The dishwasher of claim 7 , wherein the tub has a treating chamber and the dispenser is selectively disposed at any one of a plurality of locations within the treating chamber.

9. The dishwasher of claim 8 , wherein the treating chamber has a lower rack, an upper rack and a top, and the dispenser is mounted at any one of the lower rack, the upper rack or the top.

10. The dishwasher of claim 9 , further comprising a dispenser supply tube for coupling the dispenser to one of a recirculation pump or to at least one manifold tube for transporting liquid to a spray manifold, a mid-level rotatable sprayer, or an upper sprayer depending on the location of the dispenser in the treating chamber.

11. The dishwasher of claim 7 , wherein the tub has a lower rack, an upper rack and a top, and the dispenser is configured to be mounted at any one of the lower rack, the upper rack or the top.

12. The dishwasher of claim 7 , further comprising a dispenser supply tube for coupling the dispenser to one of a recirculation pump or to at least one manifold tube for transporting liquid to a spray manifold, a mid-level rotatable sprayer, or an upper sprayer depending on the location of the dispenser in the tub.
