Abstract

A laundry machine includes a cabinet with a front panel having a laundry loading/unloading opening, and a door. A washing tub is accommodated within the cabinet. A drum is rotatably arranged within the washing tub in such a way that a frontal rim of the drum faces the laundry loading/unloading opening, and a bellows connecting a rim of the laundry loading/unloading opening to the opening of the washing tub. The bellows includes a first and a second lip protruding towards the rotation axis of the drum wherein the first and second lips are each placed to hinder the passage of foreign bodies from the drum to the washing tub through a gap between the drum and the washing tub. The frontal rim of the drum is located between the first and the second lips.

First claim

The invention claimed is:

1. A front loading laundry machine comprising:
a cabinet with a front panel having a laundry loading/unloading opening,
a door for closing the laundry loading/unloading opening,
a washing tub accommodated within the cabinet and having an opening corresponding to the laundry loading/unloading opening,
a drum rotatably arranged within the washing tub in such a way that a frontal rim of the drum faces the laundry loading/unloading opening, and
a bellows connecting a rim of the laundry loading/unloading opening to the opening of the washing tub,
wherein the bellows comprises a first and a second lip protruding towards the rotation axis of said drum,
said first lip being closer to the front panel than the second lip and being adapted to hinder the passage of foreign bodies from the drum to the washing tub through a gap between the drum and the washing tub,
said second lip being adapted to hinder the passage through said gap of foreign bodies possibly trespassing said first lip, said frontal rim of said drum being located between the first and the second lips, wherein:
said first lip comprises a first lip end having a distance from said rotation axis greater than the distance of the frontal rim of said drum from said rotation axis, so that said first lip end is close to, but spaced apart from said frontal rim,
wherein the bellows comprise a return duct adapted to flow washing liquid from the bellows into the washing tub to avoid the washing liquid from accumulating in the bellows;
wherein the return duct has an intake port formed in a lower portion of the bellows at an external bellows region located between the first lip and the front panel to the washing tub;
wherein at least one channel is formed in the lower portion of the bellows passing through the base of the first and second lips, said at least one channel being adapted to fluidly connect an external region of the bellows located between the first lip and the front panel to the washing tub, in order to flow toward the washing tub the washing liquid that may accumulate in the bellows.

2. The laundry machine according to claim 1 , wherein the first and second lips are formed from a resilient material.

3. The laundry machine according to claim 1 , wherein the second lip is bent towards the first lip.

4. The laundry machine according to claim 1 , wherein said first and second lips are annular in shape, each defining a circumference which center substantially corresponds to said rotation axis of said drum.

5. The laundry machine according to claim 1 , wherein said bellows and said return duct are made in a single piece construction.

6. The laundry machine according to claim 1 , wherein the return duct comprises a housing adapted to house an anti-clog filter.

7. The laundry machine according to claim 6 , wherein the anti-clog filter is removably accommodated within said filter housing.

8. The laundry machine according to claim 1 , wherein an anti-clog filter is non-removably associated to said return duct.

9. The laundry machine according to claim 8 , wherein said anti-clog filter is non-removably associated to said return duct in proximity of said intake port.

10. The laundry machine according to claim 8 , wherein said anti-clog filter is formed integral with the bellows.

11. The laundry machine according to claim 5 , wherein the return duct comprises a housing adapted to house an anti-clog filter.

12. The laundry machine according to claim 6 , wherein said housing is placed in proximity of said intake port.

13. The laundry machine according to claim 5 , wherein an anti-clog filter is non-removably associated to said return duct.

14. The laundry machine according to claim 1 wherein the second lip has a height approximately half the height of the first lip.
