Abstract
A clothes treatment apparatus for identifying a noise course in which abnormal noise occurs, the clothes treatment apparatus including: a frame forming a skeleton of a cabinet; a cover plate surrounding the frame to form an external appearance of the cabinet; a tub provided in the cabinet; a drum rotatably provided in the tub; a drum motor configured to rotate the drum; and a vibration sensor provided on the frame.
Claims14
A clothes treatment apparatus comprising:
- a frame to form a skeleton of a cabinet;
- a cover plate surrounding the frame and forming an external surface of the cabinet;
- a tub in the cabinet;
- a drum in the tub and configured to be rotatable;
- a motor configured to rotate the drum;
- a vibration sensor on the frame and configured to sense a vibration of the frame and output a vibration signal in a time domain related to the vibration of the frame;
- and
- a processor configured to:
- convert the vibration signal in the time domain into a vibration signal in a frequency domain,
- classify, based on a rotation speed of the motor, the vibration signal in the frequency domain into a plurality of orders respectively corresponding to a plurality of noise sources of the clothes treatment apparatus, and
- determine a noise source of the plurality of noise sources based on amplitudes of a plurality of amplitudes respectively corresponding to the plurality of orders.

A method of controlling a clothes treatment apparatus, the method comprising:
- receiving a vibration signal in a time domain that is output from a vibration sensor attached to a frame forming a skeleton of a cabinet of the clothes treatment apparatus;
- converting the vibration signal in the time domain into a vibration signal in a frequency domain;
- classifying, based on a rotation speed of a motor, the vibration signal in the frequency domain into a plurality of orders respectively corresponding to a plurality of noise sources of the clothes treatment apparatus;
- and
- determining a noise source of the plurality of noise sources based on amplitudes of a plurality of amplitudes respectively corresponding to the plurality of orders.
