Definitions

  • the present invention relates to a washing machine, and more particularly, to a washing machine in which a liquid balance weight is mounted at a surface portion of a drum where a spider is also mounted.
  • FIG. 1 is a schematic sectional view illustrating a conventional washing machine.
  • the conventional washing machine comprises a cabinet 1 forming an outer appearance of the washing machine, a tub 2 mounted in the cabinet 1 and adapted to receive wash water therein, a drum 3 rotatably disposed in the tub 2 and adapted to agitate laundry (m) and wash water filled therein by use of lifters 3a, and a motor 4 mounted to a rear surface portion of the tub 2 and adapted to rotate the drum 3.
  • the cabinet 1 is formed at a front surface portion thereof with a laundry entrance/exit opening 1a.
  • a door 1b is provided to open and close the laundry entrance/exit opening 1a.
  • the tub 2 is formed at a front surface portion thereof with an opening 2a such that the opening 2a is located behind the laundry entrance/exit opening 1a.
  • the tub 2 is connected to the ceiling of the cabinet 1 by means of springs 2b such that the tub 2 is hung in the cabinet 1.
  • the tub 2 is also connected to the bottom of the cabinet 1 by means of dampers 2c such that the tub 2 is supported in the cabinet 1 in a shock absorbing manner.
  • the tub 2 has a gasket 2d interposed between the opening 2a and the laundry entrance/exit opening 1a of the cabinet 1.
  • the drum 3 has a plurality of lifters 3a uniformly protruding inward from an inner peripheral surface thereof.
  • the drum 3 also has a plurality of through-holes 3b perforated therethrough, to allow the wash water received in the tub 2 to be introduced into the drum 3.
  • the drum 3 is formed at a front surface portion thereof with an opening 3c such that the opening 3c is located behind the laundry entrance/exit opening 1a.
  • a spider 3d is mounted at a rear surface portion of the drum 3.
  • the spider 3d includes a shaft mount for the mounting of a drive shaft 4a that will be explained hereinafter, and a plurality of legs protruding from the shaft mount to be coupled to the drum 3.
  • the drive shaft 4a which is one constituent element of the motor 4, is configured to penetrate through a rear surface portion of the tub 2 to thereby be mounted to the spider 3d.
  • a liquid balance weight 7 is mounted at the front surface portion of the drum 3.
  • the liquid balance weight 7 serves to compensate for the imbalance of the drum 3.
  • the liquid balance weight 7 is internally formed with a plurality of baffles. If the interior of the drum 3 is unbalanced, contents, for example, salt water, filled in the liquid balance weight 7 is inclined in one direction opposite to the imbalance direction of the drum 3, so as to compensate for the imbalance of the drum 3.
  • the conventional washing machine has a sufficient balancing function because the liquid balance weight 7 is aligned on approximately the same axis as the laundry causing the imbalance of the drum 3.
  • the direction of a centrifugal force f2 generated by the liquid balance weight 7 is diagonally opposite to the direction of an imbalance force fl. This makes impossible the liquid balance weight 7 to achieve a desired balancing function, and may result in an increase in vibration of the drum 3.
  • additional liquid balance weight (not shown) is provided at the rear surface portion of the drum 3.
  • the additional balance weight has a risk of collision with the tub 2. If a longitudinal length of the drum 3 is reduced to prevent the collision, it results in a reduction in the capacity of the washing machine. Conversely, if the lengths of the tub 2 and cabinet 1 are increased, it requires an increased size of the washing machine.
  • the present invention is directed to a washing machine that substantially obviates one or more problems due to limitations and disadvantages of the related art. This object is attained with the subject-matter of the claims.
  • An advantage of the present invention is to provide a washing machine which is capable of minimizing generation of vibration due to imbalance, without reducing a wash capacity or increasing the size of the washing machine.
  • Another advantage of the present invention is to provide a washing machine which is capable of compensating for the imbalance of a drum regardless of the position of a subject causing the imbalance.
  • Yet another advantage of the present invention is to provide a washing machine which is capable of maximizing the volume of a liquid balance weight.

  • the drum may be formed with a plurality of fastening holes, and the liquid balance weight may be formed with a plurality of fastening bosses corresponding to the fastening holes of the drum. Accordingly, the drum and liquid balance weight may be fixed to each other as fastening members are inserted through the fastening holes and fastening bosses.
  • the liquid balance weight may be formed with a plurality of fastening holes, and the spider may be formed with a plurality of fastening bosses corresponding to the fastening holes of the liquid balance weight.
