Definitions

  • the present invention relates to a drum type washing machine, and more particularly, to a drum type washing machine in which axially-extending lifters arranged around an inner peripheral surface of a rotating 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 rotating 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 rotating tub, and a door hingably mounted to a front wall of the housing.
  • Various lifters are protruded from an inner peripheral surface of the rotating tub to a desired height while being arranged to be circumferentially spaced apart from one another around the rotating tub and to extend axially along the inner peripheral surface of the rotating tub.
  • Openings are provided at respective front ends of the water tub and rotating 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 rotating tub through the openings or to take the laundry out of the rotating tub through the openings.
  • the door When the door is closed, the water tub and rotating 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 such inconvenience, improved drum type washing machines have recently been developed.
  • the rotating tub In such a drum type washing machine, the rotating 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 positioned at a level higher than the height of the lifters at the rear end portion of the rotating tub may not be lifted by the lifters, so that it is ineffectively washed.
  • the amount of laundry lifted by the lifters at the front end portion of the rotating tub is relatively small. As a result, the lifters operate inefficiently.
  • the laundry not lifted by the lifters at the rear end portion of the rotating tub may be entangled as the lifters are rotated along with the rotating tub. As a result, the laundry may be damaged. There is also inconvenience in that 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 rotating tub is easily lifted by the lifters, and then moved toward the rear end portion of the rotating tub. As a result, the laundry tends to bunch up at the rear end portion of the rotating tub even more.
  • each lifter Since the front end portion of each lifter is rotated at a level higher than that of the rear end portion of the lifter, because the rotating tub upwardly is inclined toward the front wall of the housing, wash water raised by the lifter flows toward the rear end portion of the lifter. For this reason, the wash water is mainly sprayed by the rear end portions of the lifters, while little wash water is sprayed by the front end portions of the lifters. As a result, the laundry positioned at the front end portion of the rotating tub is insufficiently doused with the wash water.
  • the present invention has been made in view of the problems involved with the above mentioned conventional drum type washing machines, and an aspect of the invention is to provide a drum type washing machine in which axially-extending lifters arranged around an inner peripheral surface of a rotating tub which is upwardly inclined have an improved structure, thereby achieving an improvement in wash performance.
  • a drum type washing machine including: a housing; a rotating tub rotatably positioned in the housing; and at least one lifter positioned on an inner peripheral surface of the rotating tub and extending axially along the rotating tub, the lifter having, at a rear end portion thereof, a width larger than that at a front end portion of the lifter.
  • the rotating tub may be upwardly inclined toward a front wall of the housing.
  • the lifter may have a width gradually reducing as it extends from the rear end thereof to the front end of the lifter.
  • the lifter may include, at a top portion thereof, water spray holes for downwardly spraying wash water raised by the lifter.
  • the water spray holes may be longitudinally arranged in rows at the top portion of the lifter. Corresponding water spray holes in respective rows may be laterally aligned.
  • the lifter may include, at a front end thereof, with a width-enlarged portion.
  • the width-enlarged portion may have water spray holes so that a relatively large amount of wash water may be sprayed at the front end of the lifter, which is arranged at a relatively high level.
  • FIG. 1 is a sectional view schematically illustrating a drum type washing machine according to the present invention
  • FIG. 2 is a perspective view of a rotating tub from FIG. 1 , in which lifters having opposite planar side surfaces and a width gradually reducing in a forward direction in accordance with a first embodiment of the present invention are arranged on the inner peripheral surface of the rotating tub; and
  • FIG. 3 is a perspective view of another rotating tub, in which lifters having opposite curved side surfaces and a width gradually reducing in a forward direction in accordance with a second embodiment of the present invention are arranged on the inner peripheral surface of the rotating tub.
  • FIG. 1 is a sectional view schematically illustrating the configuration of a drum type washing machine according to the present invention.
  • the drum type washing machine according to the present invention includes a housing 1 having an approximately box shape to define an outer appearance of the washing machine, a drum-shaped water tub 2 installed in the housing 1 and adapted to contain wash water, a drum-shaped rotating tub 3 rotatably positioned in the water tub 2 and including spin-dry holes 4 at a peripheral wall of the rotating tub, and a drive motor 5 adapted to rotate the rotating tub 3 , in order to wash and spin-dry laundry contained in the rotating tub 3 .
  • Openings 2 a and 3 a are provided at respective front ends of the water tub 2 and rotating tub 3 , in order to allow laundry to be put into the rotating tub 3 and to be taken out of the rotating tub 3 .
  • a door 6 is hingably mounted to a front wall of the housing 1 , so as to open and close the openings 2 a and 3 a of the water tub 2 and rotating tub 3 .
  • a water supply pipe 7 for receiving wash water from an external water supply source
  • a detergent container 8 for containing detergent, and mixing the detergent with the wash water supplied via the water supply pipe 7 .
  • a drain pump 9 and a drain hose 10 are installed at the bottom of the housing 1 , in order to externally drain wash water after completion of a wash cycle.
  • the drive motor 5 is fixedly mounted to a rear end of the water tub 2 outside the water tub 2 .
  • a rotating shaft 5 a which is connected to the drive motor 5 at one end thereof, is fixedly coupled to a rear end of the rotating tub 3 at the other end of the rotating shaft, so that it transmits a rotating force from the drive motor 5 to the rotating tub 3 , thereby causing the rotating tub 3 to rotate.
  • the rotating tub 3 is upwardly inclined at a certain angle toward the front wall of the housing 1 , in order to allow the user to perform loading and unloading of laundry without bending his body.
  • the water tub 2 is upwardly inclined at a certain angle toward the front wall of the housing 1 , while being suspended in the housing 1 .

  • the inclination angle a is excessively large, the amount of laundry positioned at a rear end portion of the rotating tub 3 increases excessively, so that a degradation in wash performance occurs.
  • Lifters 20 are arranged on an inner peripheral surface of the rotating tub 3 such that they are circumferentially uniformly spaced apart from one another around the rotating tub 3 while extending axially along the rotating tub 3 .
  • the lifters 20 raise laundry contained in the rotating 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.
  • the laundry is washed.
  • the lifters 20 In order to prevent the laundry contained in the rotating tub 3 from bunching up at the rear end portion of the rotating tub 3 , as compared to the front end portion of the rotating tub 3 , due to the upward inclination of the rotating tub 3 toward the front wall of the housing 1 , the lifters 20 have a width gradually reducing as they extend from the rear end of the rotating tub 3 to the front end thereof. Such a structure of the lifters 20 will be described hereinafter, with reference to FIGS. 2 and 3 .
  • FIG. 2 is a perspective view of the rotating tub, in which lifters having opposite planar side surfaces and a width gradually reducing in a forward direction in accordance with a first embodiment of the present invention are arranged on the inner peripheral surface of the rotating tub.
  • the lifters are designated by the reference numeral 20 .
  • the lifters 20 are arranged on the inner peripheral surface of the rotating tub 3 such that they are circumferentially uniformly spaced apart from one another around the rotating tub 3 while extending axially from the rear end of the rotating tub 3 to the front end thereof, that is, throughout the length of the rotating tub 3 , in order to upwardly lift laundry contained in the rotating tub 3 .
  • Each lifter 20 has a constant height throughout the length of the rotating tub 3 while having, at a rear end thereof, a larger width than that at a front end of the rotating tub. Each lifter 20 has a width gradually reducing as it extends from the rear end of the tub to the front end thereof. Each lifter 20 also has opposite planar side surfaces.
  • each lifter 20 corresponds to the rear end of the rotating tub 3 adjacent to the rear wall of the housing 1
  • the front end of each lifter 20 corresponds to the front end of the rotating tub 3 adjacent to the door 6 .
  • the lifters 20 each have, at the rear end thereof, a relatively larger width than at the front end thereof, the amount of laundry positioned at the rear end portion of the rotating tub 3 is correspondingly reduced, so that the laundry not positioned at the rear end portion of the rotating tub 3 is positioned at the front end portion of the rotating tub 3 where the lifters 20 have a smaller width. Accordingly, it is possible to prevent laundry from bunching up only at the rear end portion of the rotating tub 3 .
  • laundry can be uniformly distributed in the rotating tub 3 . That is, although the rotating tub 3 has an upwardly inclined structure, the laundry contained in the rotating tub 3 is uniformly distributed throughout the length of the rotating tub 3 .
  • the area where the laundry is positioned between adjacent lifters 20 has a height at the rear end portion of the rotating tub 3 larger than that at the front end portion of the rotating tub 3 so that the laundry is uniformly distributed throughout the length of the rotating tub 3 . Accordingly, it is possible to rapidly and effectively wash the laundry. Also, the rotating tub 3 can rotate in a dynamically stable state.
  • the lifters 20 each have a width gradually reducing as it extends from the rear end thereof to the front end thereof, they push the laundry from the rear end of the rotating tub 3 to the front end thereof, as the tub rotates. Accordingly, the laundry positioned at the front end is prevented from shifting toward the rear end portion of the rotating tub 3 at a level lower than the front end portion of the rotating tub 3 .
  • Each lifter 20 also has a structure to spray wash water. That is, each lifter 20 has a downwardly-opened hollow structure for receiving wash water in its interior. Further, water spray holes 23 are provided at a top portion 21 of each lifter 20 . Each lifter 20 is also opened at a bottom portion 22 to communicate with openings (not shown) formed at a portion of the rotating tub 3 where the lifter 20 is arranged. Accordingly, wash water is introduced into each lifter 20 via the opened bottom portion 22 at the bottom side of the rotating tub 3 , and then downwardly sprayed through the water spray holes 23 at the top side of the rotating tub 3 . Thus, the wash water, which is mixed with detergent, can effectively permeate into the laundry, so that the laundry can be more rapidly washed.
  • spray holes may also be provided at the opposite side portions of each lifter 20 , so as to laterally spray wash water.
  • each lifter 20 contacts the inner peripheral surface of the rotating tub 3 , whereas the top portion 21 of each lifter 20 is spaced apart from the inner peripheral surface of the rotating tub 3 by a maximum distance.
