Definitions

  • the present invention belongs to the field of maintenance equipment for swimming pools and other artificial pools, in particular vacuum cleaners for swimming pools, and relates more particularly to a suction head with a central deflector for cleaning swimming pools and a vacuum cleaner equipped with such a vacuum cleaner. suction head.
  • the use of vacuum devices for cleaning swimming pool bottoms is known.
  • the suction makes it possible to reach the debris precipitated at the bottom of a swimming pool more efficiently than a traditional swimming pool brush which requires, in addition to a long and tedious sweeping, a collection of the debris packed using a landing net. for example.
  • Vacuum cleaners for swimming pools are widely marketed and can be chosen according to the specifics of each pool.
  • electric and autonomous vacuum brushes operating on battery, which generally comprise a suction head connected to a handle. The interest here is focused on the latter category.
  • Vacuum brushes can be classified into two types according to their design, filter vacuum brushes and bagged (or net) vacuum brushes.
  • a filter vacuum sweeper mainly comprises a suction head, a filter and a suction pump, and can suck up relatively heavy and small debris.
  • the debris is stored in a compartment partially delimited by the filter.
  • This type of vacuum broom is not suitable for vacuuming large debris such as leaves for example due to a low headroom between the bottom of the basin and the suction head, as well as a low storage volume in the debris compartments.
  • Such a vacuum brush is for example described in the document US 3755843 .
  • a bagged vacuum broom mainly comprises a propeller pump which delivers the raw water sucked into a large capacity bag placed above the pump.
  • the document US 3075227 describes an apparatus of this type.
  • This vacuum cleaner has certain drawbacks such as the reduced section of the suction duct which can cause the suction duct to be blocked by bulky debris. This design is likely to render the vacuum cleaner unusable for vacuuming leaves.
  • the present invention aims to overcome the drawbacks of the prior art described above, in particular the problem of accumulation of bulky debris. below the propeller of the suction pump which can lead to clogging of the pump.
  • the present invention relates to a suction head, intended for use submersible in the water of an artificial pond, comprising a body, provided with a suction duct, and a suction pump , placed inside the suction duct and comprising an electric motor coupled to a propeller, the rotation of the propeller producing a suction along the suction duct between a suction mouth and an upper opening of said duct.
  • This suction head is remarkable in that it comprises a central deflector placed between the motor and the propeller so as to prevent bulky debris from accumulating below said propeller.
  • the central deflector is integral with the propeller and is driven by the same rotational movement as the latter, for better evacuation of bulky debris towards the periphery of the suction duct.
  • the central deflector is integral with an engine block containing the engine, and remains static during the rotation of the propeller.
  • the central deflector is coaxial with an axis of rotation of the propeller.
  • the central deflector has a flat shape extending radially over a radius smaller than the radius of the helix.
  • the central deflector is a disc through which a motor shaft passes.
  • the central deflector has a curved shape.
  • the central deflector comprises an upper wall, placed between the engine and the propeller, and a side wall converging towards said engine.
  • the top wall and the side wall are respectively flat circular and curved frustoconical.
  • the upper opening of the suction duct is delimited by an annular edge able to cooperate with a flexible container for collecting bulky debris such as a bag or a net.
  • the suction head further comprises a sleeve, able to receive a handle of a vacuum brush, and a electric battery supplying the suction pump, said battery being rechargeable, removable and placed in a sealed compartment of the body.
  • the subject of the invention is also a vacuum cleaning brush, or a vacuum cleaning robot, for cleaning swimming pool floors, equipped with a suction head having one or more characteristics set out above.
  • the figure 2 , 3 and 5 show a suction head 100 mainly comprising a body 10 materializing its outer casing, a propeller pump 20 for sucking up debris, a sleeve 30 adapted to receive a handle not shown, and a battery 40 supplying the pump and placed in a compartment 14 of the body.
  • the body 10 comprises a lower shell 11, provided with a suction mouth 111, and a suction duct 12 surmounting said shell.
  • the body 10 can be formed in a single block, manufactured by molding, injection, additive manufacturing or by any other suitable process; or in several assembled parts.
  • the body 10 is made of a strong plastic material suitable for submersible use.
  • the lower shell 11 has an elongated shape, in a direction substantially perpendicular to the direction of movement of the suction head 100, tightening at its lateral ends.
  • the suction mouth 111 visible on the figures 3 and 4 , is placed in a central part of the lower shell 11, directly above the suction duct 12.
  • the suction duct 12 has a tubular shape, preferably cylindrical, extended perpendicularly to a mean plane of the lower shell 11, communicating at its lower end with the suction mouth 111, and ending at its upper end with an annular rim 121 which defines an upper opening 122 through which the debris passes, towards a debris collection bag, not shown.
  • the suction duct 12 defines an internal volume, between the suction mouth 111 and its upper opening 122, in which the suction pump 20 is placed.
  • the suction pump 20 comprises an electric motor 21 coupled to a propeller 23 whose rotation produces the suction of water, and therefore debris, along the suction duct 12 between the suction mouth 111 and the upper opening 122. Suction is carried out along current lines, shown in broken lines on the figure 4 , which pass near the blades of the propeller 23, and can therefore cause a accumulation of bulky debris, such as leaves, between the propeller 23 and the motor 21, as is the case with vacuum cleaners of the prior art.
  • the suction pump 20 is provided with a central deflector 25, positioned between the motor 21 and the propeller 23, preventing the voluminous debris sucked from piling up. below said propeller.
  • the central deflector 25 is integral with the propeller 23 and is animated by the same rotational movement as the latter in order to expel the voluminous debris sucked towards the periphery of the suction duct 12.
  • the central deflector 25, is in the form of a disc, or ring, placed coaxially with the propeller 23 and extending radially over a radius sufficient for the voluminous debris sucked up to bypass the blades of the rotating propeller 23 and pass close by of the walls of the suction duct 12 without impeding the rotation of said propeller.
  • the radius of the central deflector 25 must be smaller than that of the propeller 23 so that the suction is established in the suction duct 12.
  • the central deflector may nevertheless have a different shape and dimensions in alternative embodiments not shown.
  • the central deflector may have a convexity, or a specific curvature, to facilitate the evacuation of bulky debris towards the periphery of the suction duct.
  • the central deflector may, in addition to a circular planar upper wall forming a screen below the propeller, comprise a frustoconical side wall converging towards the motor 21 from the edge of the planar wall, thus facilitating the evacuation of bulky debris towards the periphery. of the propeller 23.
  • the frustoconical wall can be slightly curved for more efficiency.
  • the side wall has a pyramidal shape, for example, each of the faces of which is associated with one side of the square.
  • the central deflector comprises a side evacuation wall as described above, it is no longer necessary for said deflector to be coupled in rotation to the propeller, and said side wall may be integral with a housing 22 of the motor 21, or even manufactured in one piece with said housing.
  • the suction head 100 can be fitted to a vacuum brush via the sleeve 30 which can receive a handle of said brush by clipping or by any other rapid fixing means.
  • the sleeve 30 is articulated on the body 10 and can pivot in a plane perpendicular to the plane of movement of the suction head and parallel to the direction of movement of said head.
  • the displacement of the suction head 100 is for example carried out by running elements such as wheels or rollers 60.
  • the suction head 100 includes other equipment such as a charging adapter 150 for the battery.
  • the suction head thus described finds direct application in vacuum cleaners for swimming pools.
