Abstract
A washing machine has a tub, a drum configured to be rotatable inside the tub, a weight balancer coupled to the tub, a vibration sensor configured to detect vibration of the tub while the drum is rotating, and at least one processor configured to determine whether a weight balancer is damaged based on a difference between a magnitude of the detected vibration of the tub at a fundamental frequency corresponding to a rotational speed of the drum and a magnitude of the detected vibration of the tub at a harmonic frequency of the fundamental frequency.
Claims15
A washing machine, comprising:
- a tub;
- a drum configured to be rotatable inside the tub;
- a weight balancer coupled to the tub;
- a vibration sensor configured to detect vibration of the tub while the drum is rotating;
- and
- at least one processor configured to determine whether the weight balancer is damaged based on a difference between a magnitude of the detected vibration at a fundamental frequency corresponding to a rotational speed of the drum and a magnitude of the detected vibration at a harmonic frequency of the fundamental frequency.
A method for controlling a washing machine comprising a tub, a drum configured to be rotatable inside the tub, a weight balancer coupled to the tub, and a vibration sensor configured to detect vibration of the tub, the method comprising:
- detecting vibration of the tub by the vibration sensor while the drum is rotating;
- determining whether the weight balancer is damaged, based on a difference between a magnitude of the detected vibration at a fundamental frequency corresponding to a rotational speed of the drum and a magnitude of the detected vibration at a harmonic frequency of the fundamental frequency.
