Abstract

A dishwasher for treating dishes according to an automatic cycle of operation having a tub that at least partially defines a treating chamber, a slidable dish holder, an electricity-consuming component having a rechargeable battery, and a battery charging system to recharge the rechargeable battery of the electricity-consuming component when the dish holder is in the treating position.

First claim

What is claimed is:

1. A dishwasher for treating dishes according to an automatic cycle of operation, the dishwasher comprising:
a tub defining multiple walls that at least partially defines a treating chamber for receiving dishes for treating according to the cycle of operation and an open face providing access to the treating chamber;
a dish holder slidable relative to the tub through the open face between a loading position and a treating position;
a liquid spraying system having at least one sprayer configured to spray liquid into the treating chamber;
an electricity-consuming component provided on the dish holder and having a rechargeable battery; and
a battery charging system supplying electricity to the rechargeable battery and having an electrical conduit having a first connector carried with the dish holder and one end electrically coupled to the electricity-consuming component and a second connector provided with one of the multiple walls and coupled to a controller;
wherein the first and second connectors are disconnected and prevent supply of electricity through the electrical conduit when the dish holder is in the loading position and the first and second connectors are physically coupled and configured to form a conductive path to permit the supply of electricity from the controller through the electrical conduit, when the dish holder is in the treating position to recharge the rechargeable battery.

2. The dishwasher of claim 1 wherein the electricity-consuming component comprises at least one of a dispenser, a light, a liquid controller, and a sensor.

3. The dishwasher of claim 2 wherein the sensor comprises at least one of a pH sensor, a humidity sensor, and a temperature sensor.

4. The dishwasher of claim 1 wherein the at least one sprayer is selectively supplied liquid by a liquid controller.

5. The dishwasher of claim 4 wherein the dish holder comprises a dish rack and the liquid spraying system comprises multiple sprayers, with each of the sprayers defining a spray zone within the dish rack, and the liquid controller selectively supplies liquid to the multiple sprayers to control the spray of liquid in the spray zones.

6. The dishwasher of claim 5 wherein the dish rack comprises upper and lower dish racks, with the multiple sprayers provided on the upper dish rack.

7. The dishwasher of claim 6 wherein the battery charging system supplies electricity at a low voltage.

8. The dishwasher of claim 7 wherein the low voltage is a signal voltage.

9. The dishwasher of claim 8 wherein the low voltage is less than 5 volts.
