Gasket and washing machine using the same
Disclosed is a drum type washing machine having a gasket blocking a gap between a laundry entrance and a tub to prevent particles from being put therein. The present invention includes a cabinet having a first opening through which a laundry is put in, a tub having a second opening at a tub front side, a drum provided in the tub to have a third opening at a drum front side corresponding to the second opening, a rotation mans having a rotational shaft penetrating a rear side of the tub to be connected to the drum, a door opening/closing the first opening, and a gasket blocking a gap between the first and second openings to prevent leakage of water and blocking a gap between the second and third openings to prevent a particle from being put between the tub and the drum.
1. In a washing machine including a cabinet having a first opening through which laundry is put in at a cabinet front side, a tub having a second opening at a tub front side, and a drum rotatably provided in the tub to have a third opening at a drum front side, a gasket comprising:
a leakage preventing part having one end connected to a rim of the first opening and the other end connected to a rim of the second opening; and
a ring protrusion protruding toward a center of the third opening between the one and the other ends of the leakage preventing part to block a gap between the second and third openings, the ring protrusion having a front end defining a front end opening and a rear end defining a rear end opening, with the rear end being closer to the drum than the front end, and a diameter of the front end of the protrusion being greater than a diameter of the rear end opening of the protrusion.
2. The gasket as claimed in claim 1 , wherein the protrusion extends to a front end of the third opening from an inside of the leakage preventing part.
3. The gasket as claimed in claim 1 , wherein an inside diameter of the second opening is greater than that of the third opening.
4. The gasket as claimed in claim 3 , wherein the second opening is formed ahead of the third opening.
5. The gasket as claimed in claim 4 , wherein the protrusion extends to a front end of the third opening from an inside of the other end of the leakage preventing part.
6. The gasket as claimed in claim 1 , wherein the diameter of the front end opening of the protrusion is equal to an outside diameter of the third opening.
7. The gasket as claimed in claim 1 , wherein the diameter of the front end opening of the protrusion is greater than the outside diameter of the third opening.
8. The gasket as claimed in claim 1 , wherein the diameter of the rear end opening of the protrusion is smaller than the inside diameter of the third opening.
9. A drum washing machine comprising:
a cabinet having a first opening through which laundry is put in at a cabinet front side;
a tub having a second opening at a tub front side; a drum provided in the tub to have a third opening at a drum front side corresponding to the second opening;
a rotation means having a rotational shaft penetrating a rear side of the tub to be connected to the drum;
a door opening/closing the first opening; and
a gasket blocking a gap between the first and second openings to prevent leakage of water and blocking a gap between the second and third openings to prevent a particle from being put between the tub and the drum, the gasket including:
a leakage preventing part having one end connected to a rim of the first opening and the other end connected to a rim of the second opening; and
a ring protrusion protruding toward a center of the third opening between the one and the other ends of the leakage preventing part to block a gap between the second and third openings, the ring protrusion having a front end defining a front end opening and a rear end defining a rear end opening, with the rear end being closer to the drum than the front end, and a diameter of the front end of the protrusion being greater than a diameter of the rear end opening of the protrusion.
10. The drum washing machine as claimed in claim 9 , wherein the protrusion extends to a front end of the third opening from an inside of the leakage preventing part.
11. The drum washing machine as claimed in claim 9 , wherein an inside diameter of the second opening is greater than that of the third opening.
12. The drum washing machine as claimed in claim 11 , wherein the second opening is formed ahead of the third opening.
13. The drum washing machine as claimed in claim 12 , wherein the protrusion extends to a front end of the third opening from an inside of the other end of the leakage preventing part.
14. The drum washing machine as claimed in claim 9 , wherein the diameter of the front end opening of the protrusion is equal to an outside diameter of the third opening.
15. The drum washing machine as claimed in claim 9 , wherein the diameter of the front end opening of the protrusion is greater than the outside diameter of the third opening.
16. The drum washing machine as claimed in claim 9 , wherein the diameter of the rear end opening of the protrusion is smaller than the inside diameter of the third opening.
17. The gasket as claimed in claim 1 , wherein the front and rear ends are substantially normal to a center axis of the drum.
18. The drum washing machine as claimed in claim 9 , wherein the front and rear ends are substantially normal to a center axis of the drum.
