Abstract
A washing machine and method for detecting unbalance in a washing machine. A power filter may be calculated based on a detected load size, speed of a component of the washing machine, and/or a resonant frequency of the washing machine. An unbalanced indicator may be activated when a speed does not pass the power filter.
Claims20
A method for identifying unbalance in a washing machine comprising:
- detecting a load size of articles in a tub of the washing machine;
- determining power or torque required for a speed range based on the detected load size;
- and
- calculating a power filter based on the detected load size and determined power or torque required for a speed range.
1 more element
A washing machine comprising:
- a tub rotatable around an axis;
- a motor coupled to the tub;
- a sensor for detecting rotational speed of the tub or motor;
- and
- a controller coupled to the motor and the sensor, configured to
- detect a load size of articles in the tub,
- determine power or torque required for a speed range based on the detected load size, and
- calculate a power filter based on the detected load size and calculated power or torque required for the speed range.
