Abstract

A control device for a laundry appliance includes a member which need only be manually shifted through a limited range of travel, from a neutral position to which the control member is biased, in either of first and second opposing directions, to establish a desired cycle and to adjust an operational time for the cycle. The control member is provided with numerous movable contacts which are interposed between fixed contacts. Shifting of the control member a limited amount in either direction will function to engage a single pair of the contacts, while shifting the control member a further amount in the same direction causes another pair of the contacts to become engaged. In this manner, the contacts are paired to slowly increase or decrease the operational time and to also select either the next or previous operational cycle. User feedback of the selected setting is preferably provided through the use of a illuminated indicator that shifts around a track adjacent operational indicia.

Claims

1. In a clothes laundering appliance having a plurality of user selectable settings for cycle and operational times, a control device for use in setting both the cycle and operational times for a laundry operation comprising:

a control member which is manually shiftable from a neutral position through a predetermined range of travel in first and second, opposing directions;

a plurality of spaced contact members movable with said control member; and

a plurality of spaced contact elements, wherein the control member may be selectively shifted varying amounts in each of the first and second, opposing directions to interengage respective ones of the plurality of contact members and contact elements in order to selectively establish the desired cycle and operational time for the laundry operation.

2. The control device according to claim 1, wherein the control member is rotatable.

3. The control device according to claim 2, wherein the control member is rotatable only through less than 45°

.

4. The control device according to claim 3, wherein the control member is rotatable only through approximately 15°

from the neutral position in each of the first and second opposing directions.

5. The control device according to claim 1, wherein the appliance is adapted to operate in at least two different cycles, with each cycle having a wide range of selectable operational times and wherein the control device further comprises:

indicia provided about at least a portion of the control member, said indicia representing the at least two cycles and the varying operational times.

6. The control device according to claim 5, further comprising:

an indicator movable along the indicia based on the setting of the desired cycle and operational time.

7. The control device according to claim 6, wherein said indicia extends annularly about the control member.

8. The control device according to claim 1, further comprising:

a spring member for biasing the control member to the neutral position.

9. The control device according to claim 8, wherein said plurality of spaced contact members and spaced contact elements include at least two movable contacts and three fixed contacts, each of said two movable contacts being interposed between respective ones of said three fixed contacts.

10. The control device according to claim 9, wherein four contact members are interposed between three contact elements.

11. The control device according to claim 10, wherein shifting of said control member a first predetermined amount in the first direction causes a first pair of the plurality of spaced contact members and contact elements to become engaged, shifting of the control member a second predetermined amount, which is greater than the first predetermined amount, in the first direction causes a second pair of the plurality of spaced contact members and contact elements to become engaged, shifting of the control member a third predetermined amount in the second direction causes a third pair of the plurality of spaced contact members and contact elements to become engaged, and shifting of the control member a fourth predetermined amount in the second direction causes a fourth pair of the plurality of spaced contact members and contact elements to become engaged, with engagement of each pair of the spaced contact members and contact elements functioning to alter at least one of a cycle and operational time parameter of the appliance in order to establish the desired cycle and operational time for the laundry operation.

12. An appliance for laundering clothes comprising:

a cabinet including an access opening;

a lid, pivotally attached to the cabinet, for enabling clothes to be placed into and removed from the appliance through the access opening; and

means, including a control member manually shiftable through a predetermined range of travel in first and second, opposing directions from a neutral position, for setting both cycle and operational times for the appliance.

13. The appliance according to claim 12, wherein said setting means comprises a manually rotatable control member.

14. The appliance according to claim 13, wherein the control member is rotatable only through less than 45°

.

15. The appliance according to claim 14, wherein the control member is rotatable only through approximately 15°

from the neutral position in each of the first and second opposing directions.

16. The appliance according to claim 15, further comprising:

a spring member for biasing the setting means to the neutral position.

17. The appliance according to claim 12, wherein the appliance is adapted to operate in at least two different cycles, with each cycle having a wide range of selectable operational times and wherein the appliance further comprises:

indicia provided about at least a portion of the setting means, said indicia representing the at least two cycles and the varying operational times.

18. The appliance according to claim 17, further comprising:

an indicator movable along the indicia based on the setting of the desired cycle and operational time.

19. The appliance according to claim 18, wherein said indicia extends annularly about the setting means.

20. The appliance according to claim 12, wherein said setting means comprises a shiftable control member, a plurality of spaced contact members movable with said control member, and a plurality of spaced contact elements, and wherein shifting of said control member a first predetermined amount in the first direction causes a first pair of the plurality of spaced contact members and contact elements to become engaged, shifting of the control member a second predetermined amount, which is greater than the first predetermined amount, in the first direction causes a second pair of the plurality of spaced contact members and contact elements to become engaged, shifting of the control member a third predetermined amount in the second direction causes a third pair of the plurality of spaced contact members and contact elements to become engaged, and shifting of the control member a fourth predetermined amount in the second direction causes a fourth pair of the plurality of spaced contact members and contact elements to become engaged, with engagement of each pair of the spaced contact members and contact elements functioning to alter at least one of a cycle and operational time parameter of the appliance in order to establish the desired cycle and operational time for the laundry operation.

21. A method of setting both a desired cycle and operational time for a laundry operation in an appliance comprising:

rotating a control member from a neutral position in a first direction a first amount to cause a first set of electrical contacts to become engaged in order to adjust one of the cycle and the operational time; and

continuing to rotate the control member in the first direction a second amount to cause a second set of electrical contacts to further become engaged in order to adjust another of the cycle and the operational time wherein, from the neutral position through the second amount, the control member being permitted to rotate through a maximum angle of 45°

.

22. The method according to claim 21, further comprising:

limiting a permissible angular rotation of the control member to approximately 15°

in each of opposing first and second directions from the neutral position.

23. The method according to claim 21, further comprising:

providing a visual indication to a user of said cycle and operational times.

24. The method according to claim 21, further comprising:

biasing the control member to the neutral position.
