20130118210 | WASHING MACHINE HAVING VIBRATION REDUCING APPARATUS AND VIBRATION REDUCING METHOD USING THE SAME - A washing machine with a vibration reducing apparatus is capable of reducing a tub by use of the gyroscopic effect. If the drum is rotated in an imbalanced state where the laundry is positioned at a side of the drum without being uniformly distributed, a biased force is applied to a rotary shaft, and the drum performs an eccentric motion, causing vibration of the tub. The vibration of the tub is increased when the drum rotates at a high speed. The washing machine measures vibration of the tub at the high speed, and generates a vibration restraining force, thereby preventing the vibration from being transmitted to the outside due to a reaction force. The efficiency in reducing the excessive vibration of the tub is enhanced, so that the interval between the tub and the frame is reduced, thereby increasing the capacity of the washing machine. | 05-16-2013 |
20130167596 | WASHING MACHINE - A washing machine having a balancer provided with enhanced performance, and including a cabinet, a tub disposed at an inside the cabinet to accommodate washing water, a rotating tub having a cylindrical unit to form a circumferential side surface of the rotating tub and rotatively disposed at an inside the tub, a first balancer mounted at an upper portion of the rotating tub to offset an unbalanced load of the rotating tub, and a second balancer mounted at a lower portion of the rotating tub such to offset unbalanced load of the rotating tub by using a portion of the washing water at an inside the rotating tub, the second balancer includes an inner channel to store a portion of the washing water, and an outer channel formed along an outer circumference of the inner channel to offset the unbalanced load of the rotating tub. | 07-04-2013 |

20140083142 | WASHING MACHINE AND CONTROL METHOD FOR THE SAME - 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. | 03-27-2014 |
20150308029 | METHOD AND APPARATUS FOR DETERMINING AN INERTIA OF A LAUNDRY LOAD IN A LAUNDRY TREATING APPLIANCE - An apparatus and method for determining an inertia of a laundry load for a laundry treating appliance during an acceleration phase, wherein the rotational speed of a rotatable drum of the laundry is controlled based on the determined inertia. | 10-29-2015 |
20150354123 | LAUNDRY MACHINE - A laundry machine including a cabinet forming an exterior appearance of the laundry machine, a tub provided inside the cabinet, a drum rotatably provided inside the tub, a balancer housing coupled to a front portion or a back portion of the drum, and a balancing unit movably formed inside the balancer housing in order to reduce an eccentric rotation of the drum. The balancing unit further including a body forming an exterior of the balancing unit, and the body including a first mass body on one lateral side of the body, and a first wheel on another lateral side of the body and configured to roll within the balancer housing, and an elastic member provided between the first mass body and the first wheel, so as to push the first mass body and the first wheel to both lateral sides of the body. | 12-10-2015 |
20150368844 | METHOD FOR DETECTING SATELLIZATION SPEED OF CLOTHES LOAD IN A HORIZONTAL AXIS LAUNDRY TREATING APPLIANCE - A laundry treating appliance may include a rotatable treating chamber for receiving a laundry load for treatment, and a motor for rotating the treating chamber, and may be operated such that during the acceleration of the laundry load toward a satellizing speed, the satellizing of the laundry load may be detected, whereby subsequent operation of the laundry treating appliance may be controlled based on the detection. | 12-24-2015 |
20220136160 | METHOD, DEVICE, AND SYSTEM FOR DETECTING DYNAMIC IMBALANCE OF WASHING MACHINE - A dynamic imbalance detection system capable of whether a washing machine is in a dynamically imbalanced position by using big data and executing an AI algorithm or a machine learning algorithm in a 5G communications network environment built for IoT. The system includes a washing machine and a server communicating with the washing machine. The washing machine includes a vibration sensor attached to a washing machine cabinet and a controller receiving a vibration signal detected by the vibration sensor during the operation of the washing machine and processing the vibration signal into vibration data. The server receives the vibration data from the controller and trains a machine learning algorithm on a training dataset that is obtained by processing one or more features among a displacement magnitude, a displacement ratio, and a displacement phase, and determines result values of dynamic balance and dynamic imbalance labeled with the one or more features. | 05-05-2022 |
