Definitions

  • the present invention relates to a dust suction nozzle, and more particularly to an improvement of the waste collection efficiency.
  • Vacuum suckers are waste collection devices that contaminate the surface to be cleaned. They are therefore the object of many improvements aimed in particular to improve such collection.
  • the document GB 895,613 has in particular a nozzle having a flexible scraping rule having two lips articulated around a fastener and intended, on the one hand to collect the waste, and on the other hand to close the half-channel located at the back of the rule in relation to the direction of travel to improve the collection of waste.
  • US Patent 4638527 shows a triangular dust suction nozzle according to the preamble of the independent claim.
  • suckers proposing only one scraper rule, have a relatively low action by the sole solicitation of the soil.
  • a rule can impede the flow of waste in the channel.
  • the present invention aims to remedy these problems while having a nozzle of simple and compact shape.
  • the present invention is attained by means of a vacuum nozzle of substantially triangular shape, in particular having two lateral edges forming the tip of the nozzle, said nozzle being open towards the surface to be cleaned by at least two suction channels arranged respectively along each of the two side edges forming the tip of the nozzle, characterized in that the underside of said nozzle has scraper blades parallel to each other extending from each side edge towards the other side edge, in the suction channel corresponding.
  • the length of each blade in the suction channel is less than half the width of the channel at this level.
  • each blade has a base resting on the upper face of the nozzle and extending to the next blade.
  • Such an architecture allows, by the presence of a base, to avoid areas between the blades too deep where some waste could hang.
  • the upper face of the bases has a slope oriented towards the suction channel, to guide the waste ejected by the scraping effect of the blades to the suction channel, thus avoiding any waste retention zone.
  • the vacuum nozzle is isosceles-shaped having a rear edge joining the side edges, the blades then being substantially parallel to said rear edge.
  • the isosceles shape and the "closure" of the nozzle by a rear edge facilitate the use and passage of the nozzle by the symmetry provided, the rear edge also to increase the cleaning surface, for better waste collection.
  • the two channels arranged along the lateral edges meet in the front part of the nozzle, making it possible to provide a large suction zone towards the front of the nozzle.
  • the front edge of the nozzle has at least one front orifice intended to provide suction in a direction substantially parallel to the surface to be cleaned, said front suction orifice being connected to one of the channels of aspiration.
  • the present invention relates to a vacuum nozzle 1.
  • a vacuum nozzle 1 has a connection tube 2 connecting to a vacuum cleaner body, not shown, including a motor-fan capable of creating an air intake flow.
  • the connecting tube 2 opens at the sole 11 of the nozzle in contact with the soil 4 to be cleaned, via a connecting conduit 3.
  • This conduit opens on the suction channels.
  • These channels are generally configured according to the shape of the nozzle, in order to optimize the suction efficiency.
  • the suction channels as represented by the dots 10, extend in part 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 part of the nozzle.
  • the edges 5, 6 are connected by a rear edge 9.
  • the angular zone forming the tip of the nozzle comprises a front orifice 7 intended to provide 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 exemplary embodiment, has essentially only aesthetic functions and environmental protection.
  • the suction channels are closed on the one hand by an 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 an upper part 14 which, according to the embodiment, is a viewing area made by making transparent the triangular piece attached to the sole.
  • this viewing area may cover a larger field than that of the suction channel, in order to adjust the target of the waste to be extracted from the ground.
  • the viewing area has a magnifying effect, having a convex shape.
  • the waste under the viewing area is magnified, improving the visualization of the surface to be cleaned.
  • the Figures 2 and 4 present the nozzle seen from below.
  • the sole 11 of the 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 nozzle.
  • the channels 19 and 20 have front openings, that is to say in the vertical flanges of the sole, respectively 36 and 35, allowing a lateral suction substantially parallel to the surface to be cleaned.
  • the triangular shape is completed, at the rear of the nozzle, by a solid portion 40 having two locations 42 means promoting the displacement of the nozzle, which may be either PTFE-type pads or wheels.
  • the nozzle also comprises a blade 23 extending in the region 21, from the edge 5 of the nozzle to the edge 6, thus defining a front channel 18 and a rear channel 22, the front channel 18 opening at the tip of the nozzle through the opening 7 front.
  • This blade 23 has a zone 24 where is disposed a pull-wire fabric as it is known per se.
  • This blade 23 connects the edge 5 to the edge 6 as a bridge, providing a space between the face opposite the zone 24 and the upper part 14. This blade is preferably parallel to the rear edge 9 of the nozzle.
  • a second zone 28 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 respectively extending 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, extending substantially parallel to the rear edge 9 over a distance close to half the width of the channel.
  • these blades are not or are not prominent relative to the bottom plate of the nozzle.
  • each blade is shallow and limited by a base defined for each blade, each base extending to the next blade.
  • the blade 46 has a base 47 extending to the blade in front of it.
  • the depth of the suction channel being progressively variable along the side edges of the nozzle, the bases of the blades are then of different height.
  • each base may advantageously have a slope oriented towards the suction channel, in order to limit as much as possible the areas of possible jamming of the waste.
  • the sole 11 also has locations 25, 26 (cf. fig.3 ) for retractable brushes 55, 56, 57 (cf. Fig. 2 and 4 ), these brushes advantageously bordering the suction channels.
  • the nozzle In operation, the nozzle is moved on the floor 4 to be cleaned, preferably in a direction perpendicular to the rear edge 9, the user directing the nozzle to the areas to be cleaned by using, even unconsciously, the tip of the nozzle as a guide.
  • the tip of the nozzle By the presence of the front opening 7 in the tip of the nozzle, the largest waste can be sucked without the need to lift the nozzle to collect them.
  • this waste passes over the blade 23 carrying the pull-son, in the direction F. They are then directed to the body of the vacuum cleaner leaving the nozzle through the connecting pipe 3.
  • the zone visualization 14 can optionally control that some waste does not remain blocked at the blade.
  • the blades 45, 46 allow efficient solicitation of the soil fibers, including carpet-type floors, by removing, during the passage of the nozzle, the fibers of the carpet so that the suction is performed in the heart of the fibers.
  • the fibers of the carpet after their solicitation by one of the blades, are again requested by the next blade before said fiber has recovered in its initial position, which allows a longer action and in depth of the suction on the carpet to be cleaned.
  • the son and fibers remaining on the ground are solicited by the pull-son of the blade 23 which has the advantage of being bordered by the two channels 18 and 22 suction.
  • the solicitation of the self by the pull-son will, in both cases, immediately be followed, in the movement of the squeegee, by an aspiration.
  • the blades can be configured according to the blade 23 carrying the tear wire, the blades then extending over the entire width of the channel, by providing a space above them, such as a bridge, allowing the flow of air and waste, especially larger ones, to move freely over each blade. The total scraping length would be increased, which would increase the suction efficiency.
  • the blades are preferably parallel to the rear edge of the nozzle, so as to bias the fibers by a blade perpendicular to the direction of movement of the nozzle.
  • the efficiency is slightly improved when the blades have a certain inclination relative to the rear edge, for example about 20 °.
  • An explanation could be the stressing mode of the fibers which is more complex, and then more effective when the blades are not perpendicular to the direction of displacement of the nozzle.
