Abstract
A laundry washing machine and method utilize a plurality of level sensors capable of outputting signals from which the orientation of a wash tub relative to level can be determined. The signals may then be used to determine a level state of the wash tub, which may then be used to level the laundry washing machine and thereby optimize the performance thereof.
Claims20
A laundry washing machine, comprising:
- a wash tub suspended within a housing by a suspension assembly and configured to receive a load of laundry;
- a plurality of level sensors disposed at respective rotational positions about the wash tub and configured to output respective signals that vary at least in part based on the orientation of the wash tub relative to level;
- and
- a controller coupled to the plurality of level sensors and configured to perform a wash cycle to wash the load of laundry in the wash tub, the controller further configured to determine a level state of the wash tub using the respective signals output by the plurality of level sensors.

A laundry washing machine, comprising:
- a wash tub supported within a housing and configured to receive a load of laundry;
- a plurality of force sensors disposed at respective positions in the housing and configured to output respective signals that vary at least in part based on the orientation of at least a portion of the laundry washing machine relative to level;
- and
- a controller coupled to the plurality of weight sensors and configured to perform a wash cycle to wash the load of laundry in the wash tub, the controller further configured to determine a level state of the laundry washing machine using the respective signals output by the plurality of weight sensors.

A laundry washing machine, comprising:
- a wash tub supported within a housing and configured to receive a load of laundry;
- a plurality of capacitive sensors disposed at respective rotational positions about the wash tub to detect fluid in the wash tub, the plurality of capacitive sensors configured to output respective signals that vary at least in part based on the orientation of the wash tub relative to level when fluid is in the wash tub;
- and
- a controller coupled to the plurality of capacitive sensors and configured to perform a wash cycle to wash the load of laundry in the wash tub, the controller further configured to determine a level state of the laundry washing machine using the respective signals output by the plurality of weight sensors.
