Definitions

the present invention relates to a dust vacuum cleaner nozzle, and in particular an improvement in the efficiency of waste collection.
the vacuum cleaner nozzles are the collection organs for waste contaminating the surface to be cleaned. They are therefore the subject of numerous improvements aimed in particular at improving such collection.
the GB document 885,613 presents in particular a nozzle with a scraping rule flexible by presenting 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 ruler relative to the direction of travel so improve waste collection.
nozzle rectangular shape including a suction channel open to the surface to clean and comprising, in the middle of this channel, a rigid scraper blade allowing the hairs to be removed from the surface to be treated, of the carpet type so easier access to dust embedded in the fibers.
suckers by proposing only one rule of scraping, have a relatively weak action by the sole solicitation of the ground.
a rule can obstruct the circulation of waste in the canal.
the present invention aims to remedy these problems while having a nozzle of simple and compact shape.
the present invention is achieved using a vacuum cleaner nozzle substantially triangular in 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 lateral edges forming the tip of the nozzle, characterized in that that the underside of said nozzle has parallel scraper blades extending from each side edge towards the other side edge, in the corresponding suction channel.
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 bearing on the upper face of the squeegee and extending to the next blade.
Such an architecture makes it possible, by the presence of a base, to avoid areas between the blades that are too deep where some waste could risk To block.
the upper face of the bases has a slope towards the suction channel, allowing the waste to be guided ejected by the scraping effect of the blades towards the suction channel, thus avoiding any waste retention area.
the nozzle isosceles shape with a rear edge joining the lateral edges, the blades then being substantially parallel to said rear edge.
the isosceles shape and the "closing" of the squeegee by a rear edge facilitate the use and the passage of the squeegee by the symmetry provided, the edge rear also allows to increase the cleaning surface, for a better waste collection.
the two channels arranged along the lateral edges meet in the front part of the squeegee, allowing for a wide suction area towards the front of the squeegee.
the front edge of the squeegee has at least one front opening intended to ensure suction in a direction substantially parallel to the surface to be cleaned, said orifice suction front being connected to one of the suction channels.
One of the advantages of this structure is, not only to be able physically place the nozzle in the corners of the parts to be cleaned, but also to really suck at the tip and even slightly in front of this point, by the front opening thus formed.
Such a ease of use mainly avoids the use of small accessories cleaning that is available in place of the squeegee to access places narrow such as the nooks and crannies.
the present invention relates to a vacuum cleaner nozzle 1.
a sucker has a connecting tube 2 for connection to a vacuum cleaner body, not shown, including a motor fan capable of creating a air suction flow.
the connecting tube 2 opens at the level of the sole 11 of the nozzle contact with the floor 4 to be cleaned, via a connection 3.
This duct opens onto the suction channels.
These channels are generally configured according to the shape of the squeegee, in order to optimize suction efficiency.
the suction channels as represented by the dotted lines 10, extend partly along the two edges 5, 6 forming the tip of the nozzle, as well as in said nozzle tip after joining in the part central nozzle.
the edges 5, 6 are connected by a rear edge 9.
the angular zone forming the tip of the nozzle has a front opening 7 intended to ensure suction in a direction substantially parallel to the surface to be cleaned.
the nozzle has retractable brushes actuated by a pivoting pedal 8.
This pedal 8 is accessible at the cover 12 of the squeegee.
the latter in this exemplary embodiment, essentially presents only functions aesthetic and environmental protection.
the suction channels are closed, on the one hand by a internal structure produced in part during the manufacture by molding of the soleplate, such as the parts of the suction channels extending along the edges and opening through the opening 7, but also through an upper part 14 which, according to the exemplary embodiment, is a viewing area produced in making the triangular piece attached to the sole transparent.
this viewing area can cover a larger field than that of the suction channel, in order to adjust the aim of the waste to be extracted from the ground.
the viewing area has a magnifying glass effect, with a convex shape. So the waste under the area of visualization are magnified, thus improving the visualization of the surface to clean.
Figures 2 and 4 show the squeegee seen from below.
the sole 11 of the squeegee has several suction channels: a channel 19 substantially parallel to the edge 6 of the nozzle, a substantially parallel channel 20 at edge 5 of the squeegee. These channels meet in the central region 21 of the nozzle.
Channels 19 and 20 have front openings, i.e. in the vertical edges 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 back of the nozzle, by a part full 40 comprising two locations 42 of means promoting the displacement of the squeegee, which can be either PTFE type pads or wheels.
the squeegee also comprises a blade 23 extending in the region 21, from edge 5 of the squeegee to edge 6, thereby defining a front channel 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 an area 24 where a thread-pulling fabric as it is known per se.
This blade 23 connects the edge 5 to the edge 6 like a bridge, providing a space between the face opposite 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 thread-pulling fabric can be provided on an edge of the channel 22, symmetrically to the zone 24 carrying the wire puller.
the channels 19 and 20 each have blades of scraping 46 and 45 extending respectively from edge 6 and edge 5 into direction of the other edge in the suction channel.
these blades are fixed and issuing from the bottom nozzle of the nozzle while extending substantially parallel to the rear edge 9 over a distance close to the half the width of the channel.
these blades are not or are not very prominent in relation to the bottom plate of the squeegee.
each blade is shallow and limited by a base defined for each blade, each base extending up to the next slide.
the blade 46 has a base 47 extending up to the blade in front of it.
the depth of the suction channel being progressively variable along the lateral edges of the nozzle, the blades bases are then of different height.
each base can have, advantageously, a slope oriented towards the suction channel, in order to limit as much as possible any areas where waste is trapped.
the sole 11 also has locations 25, 26 (see fig. 3) for retractable brushes 55, 56, 57 (see fig. 2 and 4), these brushes bordering advantageously the suction channels.
the squeegee In operation, the squeegee is moved to the floor 4 to be cleaned, preferably in a direction perpendicular to the rear edge 9, the user directs the nozzle to the areas to be cleaned, using even unconsciously, from the tip of the nozzle as a guide.
the front opening 7 in the tip of the nozzle the largest waste can be vacuumed without the need to lift the squeegee to collect them.
this waste passes over the blade 23 carrying the wire puller, in direction F. They are then directed towards the body of the vacuum cleaner leaving the squeegee through the connection duct 3.
the visualization 14 possibly makes it possible to check that certain waste does do not remain blocked at the level of the blade.
the blades 45, 46 allow effective solicitation of the soil fibers, in particular carpet type floors, by removing, during the passage of the nozzle, the carpet fibers so that the suction is carried out at the heart of the fibers.
the fibers of the carpet after their solicitation by one blades, are again requested by the next blade before said fiber has not returned to its initial position, which allows more action long and deep suction on the carpet to be cleaned.
the threads and fibers remaining hanging on the ground are stressed by the thread puller of the blade 23 which has the advantage of being bordered by the two channels 18 and 22 suction. Whether the squeegee is moved forward or backward, the solicitation of the self by the wire puller will, in both cases, immediately followed, in the movement of the squeegee, by an aspiration.
the present invention is not limited to the embodiment present. Many variants can be envisaged. We can in particular configure the blades according to blade 23 carrying the wire puller, the blades then extending over the entire width of the channel, leaving a space at the above them, like a bridge, allowing air flow and waste, in particular the largest, to circulate freely above each blade. The length of total scraping would be increased, which would increase efficiency suction.
the blades are preferably parallel to the rear edge of the squeegee, so as to stress the fibers by a perpendicular blade in the direction of movement of the squeegee.
the efficiency is slightly improved when the blades have a certain inclination with respect to the rear edge, for example around 20 °.
a explanation could be the mode of fiber solicitation which is more complex, and therefore more effective when the blades are not perpendicular in the direction of movement of the squeegee.
