Abstract

An automatic dishwasher having a tub defining a treating chamber and a housing physically separate from the tub and defining a sump to receive liquid sprayed into the tub, the housing having an inlet fluidly connected to a liquid outlet of the tub and an outlet fluidly coupled to a sprayer located within the tub to define a recirculation path for the sprayed liquid.

First claim

What is claimed is:

1. A dishwasher for treating dishes according to a cycle of operation, the dishwasher comprising:
a cabinet defining an interior;
a tub located within the interior and at least partially defining a treating chamber, and having an opening providing access to the treating chamber;
a door moveably mounted to the cabinet between opened and closed positions to selectively close the opening; and
electrical components including both high voltage electrical components and low voltage electrical components, wherein only low voltage electrical components are located within the door; and
wherein the high voltage electrical components includes a controller and the low voltage electrical components includes a user interface for the controller.

2. The dishwasher of claim 1 wherein at least one of the low voltage electrical components is located within the cabinet.

3. The dishwasher of claim 1 wherein at least some of the high voltage electrical components are located within the cabinet and beneath the tub.

4. The dishwasher of claim 1 wherein at least some of the high voltage electrical components are arranged in a high voltage module and at least some of the low voltage electrical components are arranged in a low voltage module.

5. The dishwasher of claim 4 wherein the high voltage module includes a high voltage input and a low voltage output.

6. The dishwasher of claim 5 , further comprises a low voltage wiring harness connecting the low voltage output to the low voltage module.

7. The dishwasher of claim 6 wherein at least a portion of the low voltage wiring harness extends through the door.

8. The dishwasher of claim 7 wherein the high voltage module is located within the cabinet beneath the tub, and the low voltage module is located in the door.

9. The dishwasher of claim 5 wherein the high voltage module further comprises at least one of a recirculation pump, a blower, or a drain pump.

10. The dishwasher of claim 5 wherein the high voltage module is located at a rear of the cabinet and the door is located at a front of the cabinet.

11. The dishwasher of claim 1 , further comprising a low voltage wiring harness connecting the user interface to the controller.

12. The dishwasher of claim 1 wherein the controller is located within the cabinet at a location lower than the tub.

13. A dishwasher for treating dishes according to a cycle of operation, the dishwasher comprising:
a cabinet defining an interior;
a tub located within the interior and at least partially defining a treating chamber, and having an opening providing access to the treating chamber;
a moveable element moveably mounted to the cabinet between opened and closed positions to selectively close the opening; and
electrical components including both high voltage electrical components and low voltage electrical components, wherein only low voltage electrical components are located within the moveable element and wherein the high voltage electrical components include a controller and the low voltage electrical components include a user interface for the controller.

14. The dishwasher of claim 13 wherein the moveable element comprises at least one of a door or a drawer.

15. The dishwasher of claim 13 wherein at least one of the low voltage electrical components is located within the cabinet and beneath the tub.

16. The dishwasher of claim 13 wherein at least some of the high voltage electrical components are arranged in a high voltage module and at least some of the low voltage electrical components are arranged in a low voltage module.

17. The dishwasher of claim 13 , further comprising a low voltage wiring harness connecting the user interface to the controller.
