Abstract

A method for indicating a cycle of operation in a laundry treating appliance having a space that includes at least one electrically conductive element disposed in the space and coupled with a controller, the method includes producing in the at least one electrically conductive element the voltage or the current in reaction to the energized e-field apart from the article. Receiving in the controller a signal from the at least one electrically conductive element indicative of a value of a parameter associated with the voltage or the current of the at least one electrically conductive element. And, generating an indication, by the controller, indicative of a cycle of operation and wherein the indication increases or decreases in intensity proportional to the value of the parameter associated with the voltage or the current.

First claim

What is claimed is:

1. A method for indicating a cycle of operation in a laundry treating appliance comprising a first support element comprising a first cathode element and a first anode element spaced from the first cathode element, and a second support element comprising a second cathode element and a second anode element spaced from the second cathode element, an air gap between the first support element and the second support element, an RF generator electrically coupled to the first and second cathode and anode elements, a space for heating an article of laundry, wherein the space includes the article of laundry to be heated and at least one electrically conductive element configured to produce a voltage or a current in reaction to an energized e-field in the space and coupled with a controller, the method comprising:
producing an energized e-field by the RF generator apart from the article of laundry;
producing in the at least one electrically conductive element the voltage or the current in reaction to the energized e-field;
receiving in the controller a signal from the at least one electrically conductive element indicative of a value of a parameter associated with the voltage or the current of the at least one electrically conductive element; and
generating an indication, by the controller, indicative of a cycle of operation and wherein the indication increases or decreases in intensity proportional to the value of the parameter associated with the voltage or the current.

2. The method of claim 1 further comprising determining that the energized e-field occupies the space based on the signal.

3. The method of claim 2 wherein the intensity of the indication changes when the intensity of the e-field generates a voltage or a current value that is a danger to a user.

4. The method of claim 2 , further comprising, upon determining that the energized e-field occupies the space, determining an indication of a current cycle of operation, and generating the indication indicative of the current cycle of operation.

5. The method of claim 2 further comprising, upon determining that the energized e-field occupies the space, determining an efficiency of a current cycle of operation, and altering the energizing of the energized e-field based on the determined efficiency.

6. The method of claim 1 wherein the generated indication is a visual indication.

7. The method of claim 6 wherein the visual indication is at least one of illuminating brighter, altering a visible color, or altering a blinking pattern.

8. The method of claim 1 wherein the indication is generated in the at least one electrically conductive element.

9. The method of claim 1 wherein the generated indication is an audible indication.

10. The method of claim 9 wherein the audible indication indicates a proportional presence of the energized e-field by at least one of increasing a volume of the audible indication or changing an audible message.

11. The method of claim 1 wherein the electrically conductive element comprises at least one light bulb.

12. The method of claim 11 wherein the light bulb further comprises at least one of an incandescent bulb or a fluorescent bulb.

13. The method of claim 1 wherein the at least one electrically conductive element comprises an array of electrically conductive elements.

14. The method of claim 13 wherein the signal is further indicative of which at least one electrically conductive element in the array of electrically conductive elements is in the energized e-field in the space.

15. The method of claim 1 wherein the parameter includes at least one of the voltage or the current.

16. The method of claim 1 , wherein the energized e-field is energized in a faraday cage defining an inside space and an outside space, and which is configured to prevent an energized e-field leakage from the inside space to the outside space.

17. The method of claim 16 wherein the at least one electrically conductive element is positioned in at least one of the inside space or the outside space.

18. The method of claim 17 wherein the signal indicative of the energized e-field leakage is proportional to an amount of the energized e-field leakage.

19. The method of claim 16 wherein the signal indicates the energized e-field leakage from the inside space.
