Motorised robot for cleaning swimming pools or the like, which operates when submerged in a fluid
First Claim
1. A motorized robot (1) for cleaning swimming pools or the like which operates submerged in a fluid, comprising:
- displacement means (2) for the robot, of the wheel, brush, or caterpillar type, comprising a surface (3) of contact with a submerged surface of displacement of said swimming pool or the like,means (4) for generating, through the robot, a circulation of the fluid in which the robot is submerged, comprising;
an aspiration opening (5) for said fluid,a discharge opening (6) for the aspirated fluid,a fluid conduit (7) linking the aspiration and discharge openings,means (8) generating a stream of said fluid in said conduit,a strut (9) for lifting from the displacement surface, at least one part of said surface (3) of contact of the displacement means, said strut being movable at least between the following two positions;
a first position, termed the inactive position, in which said strut is retracted inside the robot, said surface (3) of contact of the displacement means then being able to be entirely in contact with said displacement surface,a second position, termed the active position, in which said strut stands proud of said surface (3) of contact of the displacement means, so that a part of this surface (3) of contact can no longer be in contact with the displacement surface,characterized in that said robot furthermore comprises means (10) for controlling the displacement of said strut which are activated by a motion of the fluid in said fluid conduit, said means (10) for controlling the displacement of said strut (9) between active and inactive positions comprising means (11) for opposing the motion of the fluid in the fluid conduit (7), which are movable in the fluid conduit (7) so as to at least partially obstruct said conduit or to clear the fluid conduit (7), and are tied to the strut, in such a way that, depending on the position adopted in the fluid conduit by said opposing means, the strut takes an active or inactive position.

Abstract
The invention relates to a motorized robot for cleaning swimming pools, including: means (2) for moving the robot, having a surface (3) for making contact with a movement surface submerged in the swimming pool; means (4) for generating a circulation of fluid in the robot, including an opening for the suction (5) of said fluid, and an opening for the backflow (6) of the aspirated fluid; a conduit (7) of fluid connecting the suction and backflow openings; means for generating (8) a flow of said fluid in the conduit; a strut for lifting at least part of the contact surface (3) from the movement surface, said strut being mobile between a first inactive position in which the strut is retracted inside the robot and a second active position in which the strut projects past the contact surface of the movement means in such a way that part of said contact surface can no longer be in contact with the movement surface; and means for controlling (10) the movement of the strut between its active and inactive positions, said means being activated by a movement of the fluid in the fluid conduit, and including means (11) for opposing the movement of the fluid in the fluid conduit (7), which are mobile in said conduit in such a way as to at least partially block the conduit or release it, and connected to the strut in such a way that the strut takes on its active or inactive position according to the position adopted in the fluid conduit by the opposition means.
