Definitions

  • the present invention relates to a drum type washing machine, and more particularly but not exclusively, to a drum type washing machine in which axially-extending lifters arranged around an inner peripheral surface of a rotatable tub upwardly inclinedly installed to allow easy laundry loading and unloading operations have an improved structure, thereby being capable of achieving an improvement in wash performance.
  • a conventional washing machine generally includes a housing forming an outer appearance of the washing machine, a cylindrical water tub installed in the housing and adapted to contain wash water, a cylindrical rotatable tub rotatably installed in the water tub and adapted to wash laundry contained therein, a drive motor arranged in the rear of the water tub and adapted to rotate the rotatable tub, and a door hingably mounted to a front wall of the housing.
  • Various lifters are protruded from an inner peripheral surface of the rotatable tub to a desired height while being arranged to be circumferentially spaced apart from one another around the rotatable tub and to extend axially along the inner peripheral surface of the rotatable tub.
  • Openings are provided at respective front ends of the water tub and rotatable tub such that they are opened and closed by the door.
  • the door When the door is open, it is possible to put laundry into the rotatable tub through the openings or to take the laundry out of the rotatable tub through the openings.
  • the door When the door is closed, the water tub and rotatable tub are sealed against the outside of the door. In this state, a wash cycle can be carried out.
  • drum type washing machines In order to eliminate or at least reduce such inconvenience, improved drum type washing machines have recently been developed.
  • the rotatable tub is upwardly inclined such that the opening thereof is upwardly directed, so that the user can perform loading and unloading of laundry without bending his body too much.
  • the laundry not lifted by the lifters at the rear end portion of the rotatable tub may be entangled as the lifters are rotated along with the rotatable tub.
  • the laundry may be damaged.
  • the user must disentangle the entangled laundry after completion of the washing process.
  • the laundry distributed in a relatively small amount at the front end portion of the rotatable tub is easily lifted by the lifters, and then moved toward the rear end portion of the rotatable tub.
  • the laundry tends to bunch up at the rear end portion of the rotatable tub even more.
  • wash water which is mixed with detergent and introduced into a bottom portion of the rotatable tub at the front end portions of the lifters, is raised in accordance with an upward movement of the lifters, and then downwardly sprayed through water spray holes provided at the lifters.
  • the amount of wash water sprayed through the water spray holes is small. A large amount of wash water flows toward the rear end portions of the lifters. For this reason, the wash water is mainly sprayed by the rear end portions of the lifters. As a result, the laundry positioned at the front end portion of the rotatable tub is insufficiently doused with the wash water, so that the laundry is ineffectively washed.

  • the water spray holes may be longitudinally arranged in rows, in which corresponding water spray holes in respective rows are laterally aligned.
  • the lifter may include, in the interior thereof, partition plates which divide the interior of the lifter into chambers.
  • Each partition plate may be inclined toward a front end of the lifter such that an upper end of the partition plate is closer to the front end of the lifter than a lower end of the partition plate.
  • the partition plates may have different inclination angles, respectively.
  • the partition plates may be arranged at different spaces, respectively.
  • the present invention provides a drum type washing machine comprising: a housing; a rotatable tub rotatably positioned in the housing and upwardly inclined toward a front wall of the housing an inclination angle; and at least one lifter arranged on an inner peripheral surface of the rotatable tub, the lifter including at a top portion thereof a plurality of grooves and a plurality of protrusions.

  • Lifters 20 are arranged on an inner peripheral surface of the rotatable tub 3 such that they are circumferentially uniformly spaced apart from one another around the rotatable tub 3 while extending axially along the rotatable tub 3. As the rotatable tub 3 rotates, the lifters 20 raise laundry contained in the rotatable tub 3, along with wash water, and then release the raised laundry and wash water at a certain level, thereby causing the laundry and wash water to be dropped. Thus, the laundry is washed.

  • the lifters 20 can lift a relatively large amount of laundry at their rear end portions having a relatively large height when they are positioned at the lowest level of the rotatable tub 3, while lifting a relatively small amount of laundry at their front end portions having a relatively small height. Accordingly, the rotatable tub 3 is maintained in a dynamically balanced state, so that it can uniformly wash all of the laundry while rotating smoothly.
  • the lifters 20 are arranged around the rotatable tub 3 such that they are circumferentially uniformly spaced apart from one another while extending axially from the rear end of the rotatable tub 3 to the front end thereof, that is, throughout the length of the rotatable tub 3.

  • the laundry can be stably lifted by the lifters. Accordingly, the rotatable tub can be rotated in a dynamically stable state.
  • the laundry is not entangled or lumped. Accordingly, the rotatable tub is rotated in a balanced state during a spin-dry process. It is also unnecessary to disentangle the washed laundry.
  • partition plates are arranged in each lifter to define, in the interior of the lifter, chambers respectively having approximately equal capacities.
  • each lifter has a wave-shaped structure at its top portion.
  • Water spray holes are arranged in rows at the crests and valleys of the wave-shaped structure.
