Definitions

  • the present invention relates to the field of equipment for swimming pools. It relates more particularly to an autonomous swimming pool cleaning device of the robot type.
  • the invention relates to an apparatus for cleaning a surface immersed in a liquid, such as a surface formed by the walls of a basin, in particular of a swimming pool. It is in particular a mobile swimming pool cleaning robot.
  • a cleaning robot performs said cleaning by traversing the bottom and the walls of the swimming pool basin, by brushing these walls, and by sucking the debris towards a filter.
  • Debris denotes all the particles present within the basin, such as pieces of leaves, microalgae, etc., this debris being normally deposited at the bottom of the basin or stuck on the side walls of the latter.
  • the robot is supplied with energy by an electric cable connecting the robot to an external control and power unit.
  • Such devices include a body, members for driving said body on the submerged surface, a filtration chamber formed within the body and comprising a liquid inlet, a liquid outlet, a hydraulic circuit for circulating liquid between the body. inlet and outlet through a filter device.
  • patent FR 2 584 442 aimed at a swimming pool cleaning apparatus also comprising a member for lateral lifting of the body of the apparatus which, when the apparatus changes direction of travel, laterally lifts said apparatus from the guide plane, so as to give it a line of trajectory different from the one it had just before the change of direction of travel.
  • EP1277897A1 discloses another pool cleaner according to the state of the art.
  • the object of the invention is to remedy this drawback in particular.
  • washing pool cleaning apparatus is used to describe an apparatus for cleaning an immersed surface, that is to say typically an apparatus, mobile within or at the bottom of a swimming pool, and suitable for carrying out filtration. debris deposited both at the bottom and on a wall.
  • Such a device is commonly known under the name of a swimming pool cleaning robot, when it comprises means for automated management of movements at the bottom and on the walls of the swimming pool to cover the entire surface to be cleaned.
  • an intermediate wheel articulated around an axis of rotation arranged between the front and rear wheels, at least on one of the two sides of the device, and not touching the guide plane XrYr when the robot is resting on it allows that, when at least one of the front or rear wheels is no longer in contact with the ground (the surface on which the robot is moving) due to the crossing of an obstacle, the wheel intermediary comes into contact with said obstacle and facilitates its crossing.
  • the intermediate wheel is part of the drive means, it is driven in rotation around its axis of rotation by the motor of the cleaning device.
  • the effect of the invention is therefore to allow an intermediate drive means to rest on and push on an obstacle which would protrude from the plane tangent to the front and rear wheels with the ground (this plane being the plane of contact wheels with the ground, in the absence of obstacle to cross), to facilitate crossing.
  • Another advantage of such a swimming pool cleaning device is that since the intermediate wheel is in contact with the surface on which the robot moves only in cases where the device encounters an obstacle on said surface, the cleaning apparatus with a lower energy consumption compared to the same cleaning apparatus of which all the wheels (intermediate wheel included) would be in permanent contact with said surface.
  • the axis of rotation around which the intermediate wheel is articulated is parallel to the transverse axis Yr, which corresponds to the drive axis of the front and rear wheels. In another particular embodiment, the axis of rotation around which the intermediate wheel is articulated is not parallel to the transverse axis Yr.
  • the axis of rotation of the intermediate wheel is located in the plane defined by the axes of rotation of the front and rear wheels.
  • the intermediate wheel is located longitudinally practically halfway between the front and rear wheels.
  • the intermediate wheel has a friction zone in its circumference, of substantially cylindrical shape, provided with a non-slip surface condition.
  • the intermediate wheel is driven in rotation thanks to an internal meshed zone of said wheel, of diameter smaller than that of the friction zone, this meshed zone coming to cooperate with a gear, itself driven by the wheel. rear or front wheel.
  • the meshed zone of the intermediate wheel cooperates with two gears, driven by the rear and front wheels.
  • the intermediate wheel is driven by the set of gears at a speed different from the front and rear wheels.
  • the intermediate wheel rotates in the same direction as the front and rear wheels, this intermediate wheel having a speed of rotation such that the tangential speed of the friction zone is substantially equal to that of the front wheels and back.
  • the intermediate wheel turns in the same direction as the front and rear wheels, this intermediate wheel having a speed of rotation such that the tangential speed of the friction zone is slower than that of the front wheels and back.
  • a slower speed makes it possible to reduce any slippage of the intermediate wheel on the obstacle to be crossed.
  • the drive means of the cleaning apparatus comprise an intermediate wheel on each side of the body.
  • the friction zone comprises at least one protuberance forming a lug, adapted to bear on an obstacle located at the bottom of the swimming pool to facilitate its crossing by said cleaning device.
  • the intermediate wheel is articulated around an eccentric axis of rotation. In such an embodiment, the intermediate wheel still does not touch the guide plane XrYr when the robot is resting on it.
  • the drive means of the swimming pool cleaning apparatus comprise an intermediate wheel on each side of the body, these intermediate wheels being of different diameter and / or speed of rotation.
  • the invention finds its place within a technical swimming pool environment, for example an in-ground swimming pool of the family type.
  • a submerged surface cleaning system comprises, in the present example embodiment, a cleaning apparatus 10, referred to below as a swimming pool cleaning robot, and a power supply and control unit for said swimming pool cleaning robot (not illustrated on the figures).
  • this supply and control unit can be integrated into the cleaning device.
  • the cleaning apparatus 10 is shown according to an embodiment given here by way of example, in figures 1 and 2 .
  • the type of device is here with water ejection directed towards the rear of the device relative to the running surface of the device.
  • the apparatus has water ejection directed towards the top of the apparatus, relative to the running surface of the robot.
  • the pool cleaning apparatus comprises a body 11 and driving and guiding means 12 of the body 11 on a submerged surface.
  • these drive and guide means 12 consist of front 32 and rear 33 wheels, arranged sideways to the body (see figure 1 ).
  • These drive and guide means define a guide plane on a submerged surface by their points of contact with said submerged surface.
  • Said guide plane is generally substantially tangent to the submerged surface at the point at which the device is located.
  • Said guide plane is for example substantially horizontal when the device moves on a submerged surface of the pool bottom.
  • Such a guide plane is defined in the figures of the present application along the perpendicular axes Xr and Yr. It is called the XrYr guidance plane.
  • top and bottom are defined along a straight line, perpendicular to said guide plane, a “bottom” element being closer to the guide plane than a top element.
  • the swimming pool cleaning apparatus further comprises a motor driving said drive and guide means, said motor being, in the present example, supplied with energy by the command and control unit via a waterproof flexible cable.
  • the swimming pool cleaning apparatus has at least one liquid inlet 13 and one liquid outlet 14.
  • the liquid inlet 13 is located at the base of the body (in other words under it), that is, that is to say immediately opposite a submerged surface on which the device moves in order to be able to suck up the debris accumulated on said submerged surface.
  • the liquid outlet 14 is located here on the cover, at the rear of the device.
  • the liquid outlet is in a direction facing the rear of the apparatus.
  • This arrangement is not, however, limiting, and a water outlet substantially perpendicular to the guide plane, that is to say vertically if the cleaning device rests on the bottom of the swimming pool, is also possible.
  • the apparatus comprises a hydraulic circuit connecting the liquid inlet 13 to the liquid outlet 14.
  • the hydraulic circuit is adapted to be able to ensure circulation of liquid from the liquid inlet 13 to the liquid outlet 14.
  • the apparatus comprises for this purpose a circulation pump comprising an electric motor and a propeller, said electric motor driving the propeller in rotation, said propeller being arranged in the hydraulic circuit.
  • the apparatus comprises a filtration chamber 17 interposed, on the hydraulic circuit, between the liquid inlet 13 and the liquid outlet 14.
  • the filtration chamber is in particular supplied with liquid via at least one upstream channel connecting the inlet. of liquid 13 to the filtration chamber 17.
  • the filtration chamber 17 includes a filtration basket. This filtration basket is advantageously but not necessarily removable.
  • the drive means furthermore comprise an intermediate wheel 31, disposed between the front wheel 32 and the rear wheel 33, at least on one of the two sides of the device.
  • This intermediate wheel 31 is here articulated around an axis 34 parallel to the transverse axis Yr, which corresponds to the drive axis of the front 32 and rear 33 wheels.
  • this intermediate wheel 31 is articulated. around an axis not parallel to the transverse axis.
