Abstract

A laundry washing machine having a washing tub in which a drum for receiving laundry is arranged, a filter, and an outlet duct fluidically connecting the washing tub and the filter. The filter comprises a filter seat and a filter body insertable/inserted on the filter seat, and the filter body is built in a once-piece design as a monolithic body with two hemi-shells that are connected to each other by at least one deformable connection element.

First claim

The invention claimed is:

1. A laundry washing machine comprising:
a washing tub;
a drum configured for receiving laundry arranged in the washing tub;
a filter comprising a filter seat and a filter body configured to be inserted in a first direction into the filter seat, the filter seat comprising a first outlet port and a second outlet port, each outlet port extending laterally to the first direction; and
an outlet duct fluidly connecting the washing tub to the filter;
wherein the filter body comprises a one-piece monolithic body with two hemi-shells, each hemi-shell having an external surface, and at least one deformable connection joining the two hemi-shells, wherein the external surface of the first hemi-shell comprises a first recess facing the first outlet port and the external surface of the second hemi-shell comprises a second recess facing the second outlet port when the filter body is inserted into the filter seat.

2. The laundry washing machine according to claim 1 , wherein the at least one deformable connection element is shaped as a lip.

3. The laundry washing machine according to claim 1 , wherein the at least one deformable connection element comprises two lips, each of the two lips being located a respective opposing axial end of the hemi-shells.

4. The laundry washing machine according to claim 1 , wherein the monolithic body is made of plastic.

5. The laundry washing machine according to claim 1 , wherein each of the two hemi-shells comprises at least a first closure on a first one of the hemi-shells, and at least a second closure on a second one of the hemi-shells, and therein the first closure and the second closure are configured to interact to hold the hemi-shells in a closed position.

6. The laundry washing machine according to claim 1 , wherein the filter seat comprises a third outlet port in fluid communication with a suction port of a pump, and an end of the filter body facing the suction port comprises an integrated disk extending around an outer perimeter of the outlet port.

7. The laundry washing machine according to claim 6 , wherein the integrated disk comprises a flexible material.

8. The laundry washing machine according to claim 1 , wherein the filter seat comprises a third outlet port in fluid communication with a suction port of a pump, and an end of the filter body facing the outlet port comprises a safety collar configured to extend into the outlet port.

9. The laundry washing machine according to claim 1 , wherein the filter seat comprises a third outlet port in fluid communication with a suction port of a pump, and an end of the filter body facing the suction port comprises an integrated disk extending around an outer perimeter of the outlet port and a safety collar configured to extend into the outlet port, wherein the safety collar protrudes from the integrated disk in an axial direction.

10. The laundry washing machine according to claim 1 , wherein the first recess extends into the external surface of the first hemi-shell and the second recess extends into the external surface of the second hemi-shell.

11. The laundry washing machine according to claim 1 , wherein the filter body comprises a cylindrical shape surrounding a cylindrical axis when the two hemi-shells are connected to each other.

12. The laundry washing machine according to claim 11 , wherein the first recess comprises a portion of an external wall of the first hemi-shell that is closer to the cylindrical filter body axis than the rest of the external wall and the second recess comprises a portion of an external wall of the second hemi-shell that is closer to the cylindrical filter body axis than the rest of the external wall.

13. The laundry washing machine according to claim 1 , wherein the laundry washing machine further comprises a first recirculation pump and a second recirculation pump, and wherein the first outlet port is fluidly connected to the first recirculation pump, and the second outlet port is fluidly connected to the second recirculation pump.

14. The laundry washing machine according to claim 1 , wherein the filter comprises a cap that is rotatably connected to the filter body and configured to connect the filter body to the filter seat.

15. The laundry washing machine of claim 1 , wherein each of the external surfaces are perforated with the exception of areas where the first recess and the second recess are provided.

16. The laundry washing machine of claim 1 , wherein the first recess and the second recess are arranged at the same distance from an end of the filter body.

17. A filter for filtering contaminants from liquid in a laundry washing machine, the filter comprising a filter body with a filter inlet and a filter outlet, wherein the filter body comprises a one-piece monolithic body with two hemi-shells, each hemi-shell having an external wall, and at least one deformable connection joining the two hemi-shells, wherein the external wall of the first hemi-shell comprises a first recess extending therein and the external wall of the second hemi-shell comprises a second recess extending therein.

18. The filter of claim 17 , wherein each of the external walls are perforated with the exception of areas where the first recess and the second recess are provided.

19. The filter of claim 17 , wherein the first recess and the second recess are arranged at the same distance from an end of the filter body.
