Definitions

  • the present invention relates to a laundry treatment apparatus.
  • a conventional laundry treatment apparatus includes a cabinet defining the external appearance of the laundry treatment apparatus, a tub installed inside the cabinet, a drum rotatably installed inside the tub, the drum serving to wash laundry, a power transmission unit installed to transmit torque to the drum in order to rotate the drum, and a motor fixed to the power transmission unit, the motor having a rotating shaft installed to penetrate the tub.
  • the drum may fail to maintain dynamic balance due to the position of the laundry contained in the drum, thus being rotated.
  • Dynamic balance means the state in which centrifugal force or a moment made by the centrifugal force when a rotator rotates becomes zero with respect to a rotation axis. In the case of a rigid body, dynamic balance is maintained when the distribution of the mass is constant about a rotation axis.
  • the dynamic balance of the laundry treatment apparatus may be understood as the case where, when the drum, in which laundry is stored, rotates, the distribution of the mass of the laundry is within an allowable range about the rotation axis of the drum (i.e. the case where the drum rotates while vibrating within an allowable range).
  • the state in which dynamic balance is broken is the state in which the distribution of the mass of the laundry is not constant about the rotation axis of the drum while the drum is rotating. This occurs when the laundry is not uniformly distributed inside the drum.
  • the conventional laundry treatment apparatus includes a balancing unit for eliminating the unbalance of the drum.
  • the ball balancer or fluid balancer included in the conventional laundry treatment apparatus is configured to control unbalance caused by laundry by the movement of the ball or fluid in the direction opposite the direction in which the laundry that is causing the unbalance is located, when the rotational path of the drum fluctuates due to the laundry.
  • the conventional balancing unit has difficulty in rapidly (actively) eliminating the unbalance once the unbalance has occurred.
  • the method of supplying water to the balancer in order to eliminate the unbalance requires the balancer to be mounted to the drum. In this case, however, a space is formed between the balancer and the drum, which makes it difficult to efficiently supply water to the balancer.
  • the present invention is directed to a laundry treatment apparatus that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • One object of the present invention is to provide a laundry treatment apparatus, which may actively and efficiently remove the unbalance of a drum in the transient vibration state, which is an unbalanced state of the drum in which laundry is not uniformly distributed inside the drum.
  • Another object of the present invention is to provide a laundry treatment apparatus, which is configured to efficiently drain water supplied into a balancer in order to actively eliminate the unbalance of a drum.
  • a laundry treatment apparatus includes a cabinet defining an external appearance of the laundry treatment apparatus, a drum rotatably provided inside the cabinet, the drum being configured to accommodate laundry therein, a drive unit configured to generate torque required to rotate the drum, a power transmission unit provided on one surface of the drum, the power transmission unit being configured to transmit the torque generated by the drive unit to the drum so as to rotate along with the drum, and at least one balancer provided on an inner circumferential surface of the drum, wherein water is selectively supplied into the balancer so as to eliminate unbalance occurring in the drum.
  • the water supplied into the balancer may be supplied to a front of the balancer and is drained to a rear of the balancer.
  • the balancer may be provided in a longitudinal direction on the inner circumferential surface of the drum.
  • the balancer may protrude inward into the drum to a prescribed height, thereby serving as a lifter configured to lift the laundry inside the drum.
  • the balancer may include a balancer body having a cavity therein, and a plurality of partitions configured to form a plurality of compartments inside the balancer body.
  • the partitions may be provided perpendicular to a center axis of the drum.
  • the balancer may be provided so as to communicate with the power transmission unit.
  • the water accommodated inside the balancer may be drained through the power transmission unit.
  • the laundry treatment apparatus may further include a balancer water supply unit configured to penetrate the tub so as to be exposed between the tub and the drum, the balancer water supply unit serving to supply water.
  • the balancer may include a water supply hole provided in a front end of the balancer so as to provide a space required to supply water into the balancer, and a drain hole provided in a rear end of the balancer so as to provide a space required to drain the water inside the balancer.
  • the power transmission unit may include a center portion to which a shaft is mounted, and a plurality of extensions configured to extend from the center portion in a radial direction of the drum, and the at least one balancer may include a plurality of balancers communicating with the extensions.
  • the extensions may be provided in the same number as the balancers.
  • the balancer may include a drain hole provided in a rear end of the balancer so as to provide a space required to drain water inside the balancer, and each of the extensions may include a drain connector configured to communicate with the drain hole.
  • the balancer may further include a protrusion configured to protrude from the drain hole toward the power transmission unit, and the protrusion may be inserted into the drain connector.
  • the drum may include a drum drain hole configured to communicate with the drain connector, and the drum drain hole may drain the water, drained from the balancer, to an outside of the drum.
  • the laundry treatment apparatus may further include a drain duct provided inside each of the extensions, the drain duct being configured to communicate with the drain connector so as to form a flow path, through which the water drained from the balancer is drained.
  • the laundry treatment apparatus may further include an extension drain hole provided in a distal end of each of the extensions, the extension drain hole being configured to communicate with the drain duct, and the extension drain hole may communicate with a drum drain hole provided in the drum so that the water inside the balancer is drained to an outside of the drum.
  • the present invention has the effect of providing a laundry treatment apparatus, which may actively and efficiently remove the unbalance of a drum in the transient vibration state, which is an unbalanced state of the drum in which laundry is not uniformly distributed inside the drum.
  • the present invention has the effect of providing a laundry treatment apparatus, which is configured to efficiently drain water supplied into a balancer in order to actively eliminate the unbalance of a drum.
