Definitions
- Embodiments of the present disclosure relate to a washing machine and a washing method using the same, and more particularly, to a washing machine which removes dust, lint, and other foreign substances from washing water supplied to a washing tub, and a washing method using the same.
- washing machines including drum type washing machines and pulsator type washing machines, include a washing tub that holds both laundry and washing water for washing laundry.
- Drum type washing machines wash laundry using friction between the laundry and the inner surface of the washing tub and the impact which occurs when laundry falls during rotation of the washing tub, where the washing tub is parallel to the ground.
- Pulsator type washing machines wash laundry using water that is agitated when a pulsator in the washing tub is rotated, where the washing tub is perpendicular to the ground.
- FIG. 1 is a diagram illustrating a cross-sectional view of an exemplary pulsator type washing machine having a single washing tub according to embodiments of the present invention.
- a pulsator type washing machine 100 has a filter unit 300 for removing foreign substances, and a filter guide unit 200 for mounting the filter unit 300 to the interior of the washing machine.
- a water storage tub 120 of the pulsator type washing machine 100 is positioned around a washing tub 130 which stores laundry.
- water used to wash laundry is supplied from the water storage tub 120 to the washing tub 130 during washing, and water which has been used to wash laundry (e.g., used washing water) is discharged from the water storage tub 120 during a spin-dry process using a water drain port 150.
- the used washing water may also include foreign substances such as lint, dust, dirt, and the like that have been separated from laundry, and as a result, foreign substances may become attached to an inner surface of the water storage tub 120 and remain attached when the used washing water is discharged from the washing tub 130 and the water storage tub 120.
- a filter unit 300 is used to remove foreign substances from the washing water.
- FIG. 2 is a diagram illustrating an exemplary prior art filter unit 300A which may be detachably mounted on a filter guide unit.
- lateral sides of the filter unit 300A have a first set of ribs 310A that couple to lateral sides of a filter guide unit. While coupled in this way, a gap may exist between the filter guide unit and the filter unit 300A, and washing water may unfortunately leak through the gap due to pressure caused by washing water passing through filter unit 300A. Accordingly, the foreign substances remaining in the water storage tub may flow into the washing tub without being filtered.
- the foreign substances may include dust, dirt, lint, and the like that may contaminate the laundry being washed.
- a gap between the filter unit 300A and a filter guide may gradually widen due to the pressure of the washing water.
