Definitions

  • the present disclosure relates to a washing machine, and more particularly, to a washing machine including an integral tub configured to hold or store washing water and drum configured to accommodate and rotate laundry.
  • a washing machine refers to an apparatus which eliminates foreign substances on or in laundry by agitating and rotating water together with the laundry. Washing machines may be classified into a pulsator type washing machine which washes the laundry using a water flow generated by a pulsator in the washing tub, and a drum type washing machine that washes laundry by dropping the laundry vertically, which is caused by a rotation of a drum.
  • the drum type washing machine in the related art when the laundry is washed, the laundry is put into the tub in a lateral direction by opening a door at the front of the drum type washing machine, washing water is supplied to the tub, and then the laundry is washed while a lifter in the drum lifts up and drops the laundry as the drum rotates by power from the drive motor.
  • the drum type washing machine in the related art includes the tub in addition to the drum. That is, the drum type washing machine in the related art has a structure that includes the tub to store washing water, and the drum in the tub that washes the laundry.
  • the tub is typically made of a plastic material, the tub may be easily contaminated by water scale, mold, mildew or other foreign substances when the tub is used over a long period of time.
  • the tub may be easily contaminated by water scale, mold, mildew or other foreign substances when the tub is used over a long period of time.
  • the tub becomes corroded and the laundry becomes contaminated, which may cause skin irritation or a skin disease.
  • This problem may exist in the pulsator type washing machine as well as the drum type washing machine. The reason is that the pulsator type washing machine also includes a reservoir (or tub) in a main body thereof.
  • the EP 0 381 423 A1 discloses a washing machine comprising an integrated tub/drum configured to store washing water, hold laundry and rotate.
  • a water drain guide and/or groove in or on an inner circumferential surface of the integrated tub/drum is configured to guide water in the integrated tub/drum to a discharge region of the integrated tub/drum.
  • the present disclosure has been made in an effort to provide a washing machine that has an integrated tub/drum, thereby suppressing the generation of contaminants and allowing the integrated tub/drum to be easily cleaned. Moreover the efficiency of the water drainage during the spin-drying process of the washing machine is to be improved. This object is achieved by the characterising features of claim 1.
  • the present disclosure has been made in an effort to provide a washing machine that may effectively drain washing water in an integrated tub/drum.
  • One or more exemplary embodiments of the present disclosure provide a washing machine including an integrated tub/drum that simultaneously stores washing water, holds or accommodates laundry, and rotates.

  • the fixed shaft 415 supports the water supply pipe 610 and the water drain pipe 620 in the hollow rotary shaft 410. That is, even when the hollow rotary shaft 410 rotates, the water supply pipe 610 and the water drain pipe 620 in the fixed shaft 415 do not rotate.
  • One end of the fixed shaft 415 extends or protrudes outside of the hollow rotary shaft 410 (e.g., awy from the end panel or wall of the integrated tub/drum 200), and the shaft brace or frame (e.g., fixing portion) 545 connects the one end of the fixed shaft 415 to the supporting frame 500. That is, the shaft fixing portion 545 is coupled to the supporting frame 500 to support the fixed shaft 415 so that the fixed shaft 415 does not rotate in the hollow rotary shaft 410.
  • the shaft brace or frame e.g., fixing portion
  • the rotary bearing 418 is between the hollow rotary shaft 410 and the fixed shaft 415 so that the hollow rotary shaft 410 and the fixed shaft 415 are slidable (e.g., freely rotatable) relative to each other. That is, the rotary bearing 418 enables the hollow rotary shaft 410 to rotate when the fixed shaft 415 is fixed in place.
  • the rotary bearing 418 may be or comprise a needle roller bearing.
  • the water seal (or gasket) 218 is between the hollow rotary shaft 410 and the fixed shaft 415 and is configured to block the water in the integrated tub/drum 200 from flowing into the rotary bearing 418 through an opening in the end of the hollow rotary shaft 200.
  • the supporting bearing 508 is between the hollow rotary shaft 410 and the supporting frame 500.
