Abstract

A clothes washing machine is automatically responsive to indications of high suds level conditions during washing operations to, not only counteract the high level of suds, but effectively educate the user on avoiding the reoccurrence of the conditions. A display, such as an LCD touch screen which is also preferably used to input desired cycle parameters, is integrated into the washing machine for both alerting the user to the occurrence of a high suds level condition and conveying information on how to avoid the development of the situation in the future. In order to avoid prematurely alarming the user, it is preferable to instruct the user only after a predetermined number of high level suds cycles are detected.

Claims

1. An automatic washing machine for performing laundering operations including wash and rinse cycles during which mechanical actions are imparted upon articles of clothing comprising:

a cabinet including a control panel;

a display integrated into the control panel, said display being adapted to present a plurality of visual screens to a user of the washing machine; and

a control system adapted to detect high suds level conditions developed within the washing machine during the laundering operations and for signaling the display to present information to the user concerning a high suds level condition.

2. The automatic washing machine according to claim 1, wherein the display is constituted by a touch screen display.

3. The automatic washing machine according to claim 1, wherein the control system includes means for storing information concerning the high suds level conditions.

4. The automatic washing machine according to claim 3, wherein the control system causes the display to present the information concerning the high suds level condition only after verification of the high suds level condition.

5. The automatic washing machine according to claim 4, wherein the control system verifies the high suds level condition when a predetermined number of high suds level conditions are detected during a preset number of laundering operations.

6. The automatic washing machine according to claim 1, wherein the information concerning the high suds level condition includes instructions on preventing future occurrences of high suds level conditions.

7. An automatic washing machine for performing laundering operations including wash and rinse cycles during which mechanical actions are imparted upon articles of clothing comprising:

a cabinet including a control panel;

display means, integrated into the control panel, for presenting a plurality of visual screens to a user of the washing machine; and

control means for detecting high suds level conditions developed within the washing machine during the laundering operations and signaling the display to present information to the user concerning a high suds level condition.

8. The automatic washing machine according to claim 7, wherein the display means constitutes a touch screen display.

9. The automatic washing machine according to claim 7, wherein the control means includes means for storing information concerning the high suds level conditions.

10. The automatic washing machine according to claim 9, wherein the control means causes the display means to present the information concerning the high suds level condition only after verification of the high suds level condition.

11. The automatic washing machine according to claim 10, wherein the control means verifies the high suds level condition when a predetermined number of high suds level conditions are detected during a preset number of laundering operations.

12. The automatic washing machine according to claim 11, wherein the control means signals the display means to present the information concerning the high suds level condition when four out of the last seven cycles indicate high suds level conditions.

13. The automatic washing machine according to claim 7, wherein the information concerning the high suds level condition includes instructions on preventing future occurrences of high suds level conditions.

14. A method of operating a clothes washing machine comprising:

sensing a high suds level condition developed during a laundering operation in the washing machine; and

providing information to a user of the washing machine concerning the high suds level condition through a visual display incorporated into the washing machine.

15. The method of claim 14, wherein the display provides text information to the user.

16. The method of claim 15, further comprising:

programming the washing machine for a laundering operation through the display.

17. The method of claim 16, further comprising:

providing a screen sequence on the display to instruct the user on preventing future occurrences of high suds level conditions.

18. The method of claim 14, further comprising:

verifying the high suds level condition; and

presenting the information only after verification of the high suds level condition.

19. The method of claim 18, further comprising:

verifying the high suds level condition when a predetermined number of high suds level conditions are detected during a preset number of laundering operations.

20. The method of claim 19, further comprising:

verifying the high suds level condition by detecting when four out of the last seven cycles indicate high suds level conditions.
