Abstract: A washing machine is capable of determining whether measured vibration has been caused by noise or by rotation of the inner tub. The washing machine measures vibration occurring during rotation of the inner tub and performs control operation to address causes of vibration or prevent the washing machine from toppling in the case that the vibration has actually been caused by rotation of the inner tub.

Abstract: A method of controlling a laundry treatment apparatus includes: determining whether bubbles have been generated in a tub of the laundry treatment apparatus in a state in which a second washing apparatus of the laundry treatment apparatus is operated based on a sequence of operations; and based on a determination that bubbles have been generated, reducing bubbles by (i) adding at least one first operation to the sequence of operations or (ii) replacing at least one second operation of the sequence of operations.

Abstract: A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. Each of the first and second moving masses includes a single mass made of a metal material or a mass in which a plurality of thin metal plates are coupled to overlap each other, and the first moving mass has a mass greater than that of the second moving mass.

The dynamic absorber includes a support plate coupled to the cabinet, a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet, and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. To absorb the oscillation, a time point at which the second moving mass starts relative motion with respect to the support plate is different from that at which the first moving mass starts relative motion with respect to the support plate.

Abstract: A laundry treating apparatus is provided. The laundry treating apparatus includes a cabinet, a drum accommodated in the cabinet, a tub accommodating the drum, and a dynamic absorber provided to absorb oscillation of the cabinet. The dynamic absorber includes a support plate coupled to the cabinet, a first moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet, and a second moving mass movably provided on the support plate to absorb oscillation transmitted to the cabinet. A support comes into line or point contact with a bottom surface of the first moving mass so that the first moving mass has reduced attenuation ratio in comparison to the second moving mass.
