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.

Claims

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 loading and treating positions;

a dispenser provided on the dish holder and having a rechargeable battery and wherein the dispenser is an electricity-consuming component used to dispense treating chemistry; 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 dispenser 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 controller supplies electricity at a low voltage.

3. The dishwasher of claim 2 wherein the low voltage is a signal voltage.

4. The dishwasher of claim 3 wherein the low voltage is less than 5 volts.

5. The dishwasher of claim 1 wherein the controller further comprises a DC output that supplies the electricity.

6. The dishwasher of claim 1 wherein the controller is configured to turn on or turn off a signal to control the charging of the rechargeable battery.

7. The dishwasher of claim 1 wherein the dispenser is configured to dispense treating chemistry while consuming electricity supplied from the rechargeable battery.

8. 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 loading and treating positions;

a sensor 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 a second connector provided with one of the multiple walls and coupled to an electricity source configured to be coupled to an AC power supply and having a DC output;

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 electricity source through the electrical conduit, when the dish holder is in the treating position to recharge the rechargeable battery.

9. The dishwasher of claim 8 wherein the sensor comprises at least one of a pH sensor, a humidity sensor and a temperature sensor.
