Abstract

A swimming pool cleaning assembly that has at least one ultrasonic generator, a swimming pool cleaning machine including a support frame, a housing shell provided with a bottom wall and arranged around the support frame, a driver located in the housing shell, advancer supported by the frame and arranged to be place, in use, on a surface to be cleaned of a swimming pool and driven, at least one water suction opening provided in the bottom surface of the housing shell, which is designed to be put in fluid communication with water suction, driver being tightly sealed in the housing shell and electrically connectable to the supply, the ultrasonic generator being arranged at the bottom wall facing, in use, the surface to be cleaned.

First claim

The invention claimed is:

1. A swimming pool cleaning assembly comprising at least one ultrasonic wave generator which generator severs particles of microparticles of scales from a side wall or the bottom of the swimming pool by ultrasonic waves, Comprising: a swimming pool cleaning machine including a support frame, a housing shell provided with a bottom wall and arranged around the support frame, a driving structure located in said housing shell, an advancing structure supported by said frame and arranged to be placed, in use, on a surface to be cleaned of a swimming pool and driven by said driving structure, at least one water suction opening provided in the bottom surface of said housing shell, which is designed to be put in fluid communication with water suction structure, said driving structure being tight sealed in the housing shell and electrically connectable to supply structure, wherein at least one said ultrasonic generator is arranged at said bottom wall facing, in use, said surface to be cleaned, at least one front and rear brushing member members and at least one intermediate brushing member for brushing the surface to be cleaned, mounted for rotation on said frame and driven by said driving structure, and comprising said at least one front and rear brushing member and at least one intermediate brushing member and in that are arranged substantially parallel to one another.; wherein the intermediate brushing member is spaced apart from the front and rear brushing members; and wherein the intermediate brushing member is arranged to rotate about an axis of rotation.

2. A cleaning assembly as claimed in claim 1 , comprising resilient structure suitable for yieldingly biasing said ultrasonic generator towards said surface to be cleaned wherein the intermediate brushing member is positioned between the front and rear brushing members.

3. A cleaning assembly as claimed in claim 1 , comprising at least one front and rear brushing member for the surface to be cleaned, mounted for rotation on said frame and driven by said driving structure wherein the axis of rotation of the intermediate brushing member is parallel to an axis of rotation of each of the front and rear brushing members.

4. A cleaning assembly as claimed in claim 3 1, comprising a first motion transmission structure arranged to transmit motion from said driving structure to said at least one brushing member of the front and rear brushing members.

5. A cleaning assembly as claimed in claim 4 , wherein said first motion transmitting structure comprises at least one transmission belt wound around a driving pulley driven by said driving structure and a driven pulley rigid in rotating with said at least one brushing member of the front and rear brushing members.

6. A cleaning assembly as claimed in claim 3 1, wherein said at least one of the front and rear brushing member comprise each members comprises a cylinder provided with a plurality of brushing lugs.

7. A cleaning assembly as claimed in claim 1 , comprising at least one intermediate brushing member for said surface to be cleaned, mounted for rotation on said frame through said bottom wall and arranged to be driven by said driving structure comprising at least one water suction opening provided in the housing shell, which is designed to be put in fluid communication with a water suction structure.

8. A cleaning assembly as claimed in claim 7 1, comprising a second motion transmission structure arranged to transmit motion from said driving structure to said at least one intermediate brushing member.

9. A cleaning assembly as claimed in claim 7 1, comprising a second motion transmission structure arranged to transmit motion from said driving structure to said at least one intermediate brushing member, wherein second motion transmission structure comprises at least one belt wound around a driving pulley designed to be driven by said driving structure, and a driven pulley rigid in rotation with said at least one intermediate brushing member.

10. A cleaning assembly as claimed in claim 7 9, wherein said second motion transmission structure is designed to cause said at least one intermediate brushing member to rotate in a direction opposite to that of said a first transmission structure that is arranged to transmit motion from said driving structure to at least one brushing member of the front and rear brushing members.

11. A cleaning assembly as claimed in claim 7 1, comprising a plurality of ultrasonic generators arranged aligned between said at least one opening and said at least one intermediate brushing member.

12. A cleaning assembly as claimed in claim 7 1, wherein said at least one intermediate brushing member comprise each a cylinder provided with a plurality of brushing lugs.

13. A cleaning assembly as claimed in claim 1 , comprising a third motion transmission means operatively connected between arranged to transmit motion from said driving structure and said advancing structure.

14. A cleaning assembly as claimed in claim 1 13, wherein said third motion transmission structure comprises at least one transmission belt wound around at least one driving pulley arranged to be driven by said driving structure, and at least one driven pulley arranged to drive said advancing structure.

15. A cleaning assembly as claimed in claim 1 , wherein said advancing structure are rigid in rotation and coaxial with said at least one brushing member of the front and rear brushing member or said at least one intermediate brushing member.

16. A cleaning assembly as claimed in claim 1 , wherein said advancing structure comprises at least one pair of tracks, at least one driving wheel, and at least one idle transmission wheel for said at least one pair of tracks, said at least one driving wheel being operatively connectable to said driving structure.

17. A cleaning assembly as claimed in claim 16 1, wherein said comprising a programmable control unit can that is arranged to be remotely operated.

18. A cleaning assembly as claimed in claim 1 , comprising a controllable programmable control unit, and a steering system arranged to be controlled by said programmable control unit.

19. A cleaning assembly as claimed in claim 18 , wherein said steering system comprises:
a differential system inserted on an axle comprising semiaxes, each semiaxis of the semiaxes supporting a respective driving wheel of at least one pair of tracks, and a braking structure for each semiaxis.

20. A cleaning assembly as claimed in claim 1 7, comprising a programmable control unit designed that is arranged to control at least one out of said driving structure and/or said a suction structure.

21. A cleaning assembly as claimed in claim 20 19, wherein said braking structure comprises an electromagnetic disc brake.

22. A cleaning assembly as claimed in claim 1 , wherein said driving structure comprises a reversible electric motor carried by said support frame inside said housing shell.

23. A cleaning assembly as claimed in claim 1 , wherein said comprising a supply structure for said driving structure, wherein the supply structure comprises an electric battery.

24. A cleaning assembly as claimed in claim 1 7, wherein said water suction structure comprises a pump pumping member suitable for sucking water from said at least one opening.
