20110277269 | Robot cleaner with improved dust collector - A robot cleaner including a suction hole to suction dust, a blower to generate a suction force to suction the dust, a dust collector to receive the dust suctioned by said suction force through the suction hole, and a rotating brush to sweep up and collect the dust into the dust collector through the suction hole by a drive force of the rotating brush. The dust collector includes a backflow preventing member movable between an open position and a closed position. The backflow preventing member is pivotably rotatable in an air suction direction by the suction force of the blower to the open position and is adapted to return to the closed position to prevent the dust in the dust collector from being discharged through the suction hole upon stoppage of the blower. | 11-17-2011 |
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 |
20130118211 | DRUM WASHING MACHINE - A drum washing machine provided with a dynamic absorber capable of reducing the vibration of a low frequency band, the drum washing machine including a body, a drum rotatably installed at an inside the body, a tub installed to vibrate while surrounding the drum, and a dynamic absorber installed at the tub to directly reduce vibration delivered to the tub, wherein the dynamic absorber includes a mass body and an elastic member configured to elastically support the mass body for the mass body to move toward a direction of the vibration of the tub to reduce the vibration of the tub. | 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 |
20130227812 | ROBOT CLEANER WITH IMPROVED DUST COLLECTOR - A robot cleaner including a suction hole to suction dust, a blower to generate a suction force to suction the dust, a dust collector to receive the dust suctioned by said suction force through the suction hole, and a rotating brush to sweep up and collect the dust into the dust collector through the suction hole by a drive force of the rotating brush. The dust collector includes a backflow preventing member movable between an open position and a closed position. The backflow preventing member is pivotably rotatable in an air suction direction by the suction force of the blower to the open position and is adapted to return to the closed position to prevent the dust in the dust collector from being discharged through the suction hole upon stoppage of the blower. | 09-05-2013 |
20150041270 | LOWER SHOCK-ABSORBING APPARATUS FOR WASHING MACHINE PACKING - Disclosed is a lower shock-absorbing apparatus for washing machine packing that supports and protects a washing machine to prevent damage to the washing machine during transportation of the washing machine.
