Abstract

A method of operating a dishwashing machine including determining user satisfaction with a dishwashing cycle, adjusting at least one operational parameter of the dishwashing cycle based on the user satisfaction, and incorporating the adjusted operational parameter into a subsequent dishwashing cycle.

First claim

The invention claimed is:

1. A method of operating a dishwashing machine, comprising:
determining user satisfaction with a dishwashing cycle, including soliciting by requesting and prompting, through a display, user input regarding each of a plurality of different characteristics of dishwasher performance, receiving individual user-input signals indicative of the user satisfaction for each of the plurality of different characteristics for the dishwashing cycle, and identifying individual, distinct unsatisfactory characteristics of dishwasher performance based on the user-input signals, wherein the plurality of characteristics of dishwasher performance encompasses at least three different characteristics of dishwasher performance and includes at least washing quality and drying quality, and identifying the unsatisfactory characteristic of dishwasher performance includes identifying a stage of the dishwashing cycle exhibiting unsatisfactory performance,
adjusting at least one operational parameter of the dishwashing cycle based on the user satisfaction, and
incorporating the adjusted operational parameter into a subsequent dishwashing cycle.

2. The method of claim 1 , further comprising:
identifying at least one operating condition of the dishwashing cycle associated with the user satisfaction,
wherein the adjusted operational parameter is incorporated into a subsequent dishwashing cycle when the identified operating condition is present in the subsequent dishwashing cycle.

3. The method of claim 1 , wherein the plurality of characteristics of dishwasher performance further includes noise generated during the dishwashing cycle.

4. The method of claim 3 , wherein the plurality of characteristics of dishwasher performance further includes dishwashing cycle duration.

5. The method of claim 1 , wherein adjusting at least one operational parameter of the dishwashing cycle includes:
(i) selecting an operational parameter associated with the unsatisfactory characteristic of dishwasher performance, and
(ii) adjusting the selected operational parameter.

6. The method of claim 5 , wherein adjusting the selected operational parameter includes determining whether additional adjustments are available for the selected operational parameter.

7. The method of claim 1 , wherein identifying the unsatisfactory characteristic of dishwasher performance includes identifying a location within the dishwashing machine exhibiting unsatisfactory performance.

8. The method of claim 7 , wherein identifying the unsatisfactory characteristic of dishwasher performance includes identifying one of a plurality of ware types not satisfactorily cleaned.

9. The method of claim 8 , wherein adjusting at least one operational parameter of the dishwashing cycle includes:
(i) selecting at least one operational parameter associated with the identified stage, the identified location, and the identified ware type, and
(ii) adjusting the selected operational parameter to improve cleaning quality.

10. A method of operating a dishwashing machine, comprising:
operating the dishwashing machine in accordance with a dishwashing cycle,
communicating with a plurality of sensors to determine operating conditions present in the dishwashing cycle,
determining user satisfaction with dishwasher performance at the conclusion of the dishwashing cycle based on soliciting user input regarding a plurality of characteristics of dishwasher performance, wherein the plurality of characteristics of dishwasher performance are individually solicited and evaluated and encompasses at least three different characteristics of dishwasher performance and includes at least washing quality and drying quality,
adjusting an operational parameter of the dishwashing cycle based on the user satisfaction,
identifying at least one operating condition of the dishwashing cycle associated with the user satisfaction, and
incorporating the adjusted operational parameter into a subsequent dishwashing cycle when the identified at least one operating condition is present in the subsequent dishwashing cycle.

11. The method of claim 10 , wherein communicating with the plurality of sensors comprises:
communicating with a soil sensor to determine the soil level of fluid in the dishwashing machine, and
communicating with a temperature sensor to determine the temperature of fluid in the dishwashing machine.

12. The method of claim 10 , further comprising:
determining a number of user preferences for the dishwashing cycle,
wherein adjusting the operational parameter includes adjusting at least one operational parameter associated with at least one of the number of user preferences when a user is determined to be satisfied with the dishwashing cycle.

13. The method of claim 10 , wherein incorporating the adjusted operational parameter into the subsequent dishwashing cycle includes:
(i) communicating with the plurality of sensors to determine operating conditions present in the subsequent dishwashing cycle,
(i) determining that at least one operating condition present in the subsequent dishwashing cycle is equal to the identified operating condition, and
(ii) modifying the subsequent dishwashing cycle to include the adjusted operational parameter.

14. The method of claim 10 , further comprising determining whether the operational parameter can be adjusted.

15. The method of claim 14 , wherein determining whether the operational parameter can be adjusted includes:
(i) identifying a current value of the operational parameter,
(ii) comparing the current value of the operational parameter to a predetermined threshold of the operational parameter, and
(iii) generating an error message when the current value is equal to the predetermined threshold.

16. The method of claim 10 , wherein the plurality of characteristics of dishwasher performance additionally includes noise generated during the dishwashing cycle.

17. The method of claim 16 , wherein the plurality of characteristics of dishwasher performance further includes dishwashing cycle duration.

18. The method of claim 10 , further comprising: identifying an unsatisfactory characteristic of dishwasher performance based on the user input, wherein identifying the unsatisfactory characteristic of dishwasher performance includes identifying a location within the dishwashing machine exhibiting unsatisfactory performance.

19. The method of claim 18 , wherein identifying the unsatisfactory characteristic of dishwasher performance includes identifying one of a plurality of ware types not satisfactorily cleaned.
