Definitions

  • the present invention relates to a dust vacuum cleaner, and more particularly an improvement of the ergonomics of the vacuum cleaner constituting the waste collection member that contaminates the surface to be cleaned.
  • Document FR 2 439 577 shows an improvement of this device by a suction nozzle having a double articulation between the base of the where the suction channels and the connecting tube connecting the vacuum cleaner.
  • Such a nozzle makes it easier to use: independently of the floors cleaned, especially by the presence of one of the joints outside the active suction surface, which reduces the thrust force of the nozzle during cleaning. Indeed, especially when the nozzle is moved forward, the vertical component of the thrust force of the nozzle is directly exerted on the wheels and not on the sole which makes it possible to to suppress the increase of the friction of the nozzle on the ground.
  • the present invention aims to overcome the disadvantages of the prior art by having an improved performance nozzle for a plurality of soils, while keeping a compact shape to the nozzle.
  • the suction nozzle is open towards the surface at cleaning by at least one suction channel formed in the sole of the nozzle and connected, by two articulated pipes, to a connecting tube connected to a frame of vacuum cleaner, the first tube being articulated on the sole, the second tubing being articulated on the first, at a distance from the latter, along axes substantially parallel, said nozzle having at least one wheel to be prominent relative to the sole, said wheel being mounted on the axis articulation of the second manifold, the nozzle further comprising a hood covering the sole, characterized in that the points of articulation of the second tubing on the first are located between the sole and the hood, and that the sole has openings for passage of the wheels.
  • the first tubing is connected, in opposition to the second manifold, to a connection zone leading to the suction channels.
  • This tubing is even shorter than the connection zone is reported on the sole and extends longitudinally rearward of said sole. Values less than 5 cm are thus reached with regard to the length of the first articulated pipe.
  • the distance between the axes of rotation of the tubes is preferably less than 5 cm, which allows, simply by a slight rotation of the second tubing, to leave or not the wheels of the sole.
  • the vacuum nozzle is substantially shaped triangular shape, in particular with two lateral edges forming the tip of the nozzle, said nozzle having two channels arranged along both edges sides forming the tip of the nozzle, and in that the openings of passage wheels are located around the center of gravity of the base triangular of the sole.
  • Such an architecture in particular by arranging the wheels in the vicinity of the center of gravity of the triangular sole and not the periphery as it is usually the case in rectangular suckers, helps to balance all when the wheels are active.
  • the present invention relates to a vacuum nozzle 1.
  • a vacuum nozzle 1 Such a nozzle has conduits 31, 30 and a tube 2 for binding to a body vacuum cleaner, not shown, including a motorcycle fan likely to create an air intake flow.
  • the conduit 31 opens at the sole 11 of the nozzle in contact with the soil to be cleaned, via a part 33 defining in part a connection area 32 opening on the suction channels.
  • These channels are usually configured according to the shape of the nozzle, so to optimize the suction efficiency. In the example presented where the nozzle is triangular shape, the suction channels extend partly along the two edges 5, 6 forming the tip of the nozzle, as well as in said tip of the nozzle after joining in the central portion 21 of the nozzle.
  • the angular zone forming the tip of the nozzle comprises a front orifice 7 intended to ensure suction in a direction substantially parallel to the surface to be cleaned.
  • the nozzle has retractable brushes actuated by a pedal 8 pivoting.
  • This pedal 8 is accessible at the hood 12 of the nozzle.
  • the latter in this embodiment, essentially only presents functions aesthetic and environmental protection.
  • the suction channels are closed, on the one hand by a internal structure made in part during the manufacture by molding of the sole, such as the parts of the suction channels extending along the edges and opening through the opening 7, but also by the upper part 33 partly comprising the connection zone 32.
  • connection zone 32 is obtained by the assembly of the upper piece 33 on the sole, using three screws arranged at the 16.
  • Other equivalent means, such as clips, may be used to return the piece 33 on the sole.
  • This upper piece 33 comprises a viewing area 14 of the waste on the surface being cleaned, made by making transparent a significant part of said piece triangular reported on the sole.
  • the hood 12 then has a simple opening opposite the zone of visualization 14.
  • Figure 2 shows the nozzle seen from below.
  • the sole 11 of nozzle has several suction channels: a channel 19 substantially parallel to the edge 6 of the nozzle, a channel 20 substantially parallel to the edge 5 of the nozzle. These channels meet in the central region 21 of the sucker, close of the connection zone 32.
  • the channels 19 and 20 have openings front, that is to say in the vertical edges of the sole, respectively 36 and 35, allowing lateral suction substantially parallel to the surface to clean.
  • the triangular shape is completed, at the rear of the nozzle, by a part 40 with two windows 42 through which are housed means facilitating the displacement of the nozzle, which can be either skids PTFE type, or wheels.
  • the nozzle further comprises a blade 23 extending in the region 21, the edge 5 of the nozzle at the edge 6, thus defining a channel before 18 and a rear channel 22, the front channel 18 opening at the tip of the nozzle by the front opening 7.
  • This blade 23 has a zone 24 where is disposed a pull-out fabric as it is known per se.
  • This blade 23 connects the edge 5 to the edge 6 as a bridge, leaving a space between the face opposite the zone 24 and the viewing zone 14. This blade is preferably parallel to the rear edge 9 of the nozzle.
  • a second zone 124 carrying a pull-out fabric may be provided on a border of the channel 22, symmetrically to the zone 24 carrying the pull-son.
  • the channels 19 and 20 each have scraping blades 46 and 45 extending respectively from the edge 6 and the edge 5 towards the other edge in the suction channel.
  • these blades are fixed and issuing from the bottom plate of the nozzle while extending substantially parallel to the rear edge 9 for a distance close to half of the width of the canal.
  • these blades are slightly prominent by compared to the bottom plate of the nozzle.
  • the nozzle also comprises brushes 55, 56, 57, said brushes being retractable through the sole using of a mechanism 25 visible in FIG. 3 and not further described herein. request.
  • a mechanism 25 visible in FIG. 3 and not further described herein. request.
  • the wheels 43 mounted on a rod 44 and connected to the conduits 30, 31, as will be explained later.
  • the ducts 30, 31 are articulated respectively along an axis x-x 'and y-y', more particularly visible on the Figures 5 and 6. These axes are substantially parallel to the rear edge 9 of the nozzle.
  • the conduit 30 is articulated on the conduit 31, itself articulated on the sole of the sucker.
  • the conduit 30 has two side walls 300 directed towards bottom and in which are formed two orifices 301 defining the axis x-x '.
  • the duct 31 has two orifices 311 located partly rear of said conduit, on the x-x 'axis, between the orifices 301.
  • the x-x' axis is physically materialized by the rod 44 for supporting the wheels 43, the latter being mounted at each end of the rod 44.
  • two grooves 47 are formed in inner edge of the passages 42 of the wheels to receive the rod 44. These grooves are only rest points of the rod 44 in the low position.
  • conduit 31 comprises, in the front part, pins 312 defining the y-y 'axis.
  • sole 11 comprises bearings 48 receiving pins 312, the latter being force-fitted into the bearings 48.
  • the conduit 31 is articulated, by the pins 312, on the sole of the sucker, substantially in the vicinity of the center of gravity of the nozzle.
  • the conduit 30 is articulated on the conduit 31 via the rod 44, this articulation being floating following the rotational movement of the conduit 31 around his articulation.
  • the two axes of articulation are located at a distance from each other, this distance resulting from a compromise between the maneuverability of the sucker that would be less if distance was important, and lack of interest by the inefficiency of a double articulation if the distance is too small. In practical, a distance between 3 and 5 cm separates the two axes of rotation x-x 'and y-y'.
  • the first tubing 31 has a relatively small length 1, less than 5 cm, such that it is represented figure 8. This figure also makes it possible to go account of the arrangement of the pipes, and in particular the covering large potential of the tubing 31 on the tubing 30 during its pivoting.
  • Figures 8 and 9 also show the extreme positions of different tubings when handling the nozzle. So, figure 8, when the user moves the nozzle forward, it can rotate the tubing 30 around the axis x-x 'materialized by the rod 44, this pivoting being realized at an angle ⁇ of up to 35 °. At this angle value reached, the tubing 30 abuts against a vertical wall 310 weakly pronounced on the outer casing of the upper part of the tubular 31.
  • This first pivot allows in particular to keep the nozzle well in contact with the surface to be cleaned when moving forward, with significant latitude with respect to the angular position of the tubes of connection related to the nozzle.
  • Such a nozzle also has the following remarkable phenomenon, in use on carpeted floors. It is known that for these types of coating, vacuuming is made tedious by force necessary to move the nozzle, the latter sinking into the hairs of the carpet and reducing the flow of air sucked which leads to a local increase of depression.
  • a piece of blocking 70 can be added to the nozzle.
  • Such a room is located behind of the hinge 30 and can be actuated by the pedal 8 when the user want to take out the brushes.
  • FIG. 11 shows the suction nozzle brushes retracted, while Figure 12 shows the nozzle brushes outlets.
  • the blocking member 70 passes under the hinge 30 so as to block the wheels in high position.
  • the reader may refer to the French application bearing the registration number FR 0307438 which details said brush outlet mechanism such as present.
  • the pedal 8 when actuated to make remove the brushes from the nozzle, rotate an angled rod 50 which leads to its two horizontally movable trolleys, the latter, by a surface of inclined cam during this horizontal movement operate two rockers carrying the brushes, movable vertically in relation to the sole, against the return force of two springs.
  • the piece 70 carries a notch 71 accommodating the rod 50.
  • the part 70 advantageously has an inclined surface 72 in its front part, allowing the wheels to be moved upwards when these past are out. It is therefore not necessary to position the tube 30 in a particular position, in particular that indicated in FIG. 9 where the wheels are raised to lock said wheels.
  • the blocking is realized whatever the initial position of the joint.
  • the nozzle rests on the brushes, favoring, on the type of soil concerned, that is to say the smooth soils, the Lateral displacement of the squeegee by preventing the wheels from rubbing on the ground when moving the nozzle in a direction that does not correspond to the wheel running direction.
