Definitions

  • the present invention relates to a dust suction nozzle, and more particularly to an improvement of the waste collection efficiency by such a nozzle.
  • the present invention is aimed at low power vacuum cleaners, such as those held by hand by a handle and resting on the ground by a nozzle connected to the body of the vacuum cleaner.
  • vacuum cleaner will designate such devices.
  • Broom vacuum cleaners frequently have batteries that allow them greater ease of use, but further limit the available power.
  • the document EP 1 033 101 describes a broom vacuum cleaner whose handle is collapsible.
  • the document US 5,107,567 describes a brush vacuum connected to the sector, the nozzle of this vacuum having a central suction opening, bordered on one side by a brush operated by a pedal located at the cover of the nozzle.
  • the latter is equipped with small wheels.
  • the brush is arranged in the suction channel and the nozzle has large wheels facilitating its movement.
  • One of the aims of the present invention is to provide a suction nozzle for vacuum cleaner low power, whose efficiency has been optimized for the available power, to improve the waste collection efficiency for such devices .
  • a suction nozzle of substantially rectangular shape comprising a soleplate intended to move on a surface to be cleaned by means of wheels or pads, said soleplate being covered by a hood , and having a suction channel open to the surface to be cleaned and extending over the width of the nozzle by connecting the two side edges of said nozzle, and a connecting tube to the body of the vacuum arranged at the rear of the nozzle, said tube being connected to the suction channel towards the middle thereof by a conduit, characterized in that the suction channel is delimited by a front wall and a rear wall, and in that the front wall forms a symmetrical circular arc with respect to the middle of the channel.
  • the arcuate shape of the front edge delimiting the suction channel allows when the nozzle is moved forward on carpeted surfaces, firstly to solicit the carpet pile differently by a movement having a lateral component and on the other hand to avoid having a frontal "leading" edge that can make it difficult to move the nozzle on such surfaces.
  • the rear wall delimiting the suction channel has the same configuration, forming a circular arc symmetrical with respect to the front wall.
  • the radius of curvature presented by the front wall and / or rear delimiting of the suction channel is greater than 500 mm and preferably less than 1000 mm.
  • the effectiveness of the nozzle placed on a vacuum cleaner given its low power, has good values when the width of the suction channel at the side edges of the nozzle is less than 15 mm, and when the width of the suction channel in the middle is between 20 and 25 mm.
  • the front and rear walls delimiting the suction channel are prominent with respect to the sole. These walls are in a way scraping rules that allow when they pass on the floors mentioned, on the one hand to scrape the carpet hairs, and on the other hand to eject the dust when the hair resumes its position, after the solicitation of the walls.
  • the depth of the suction channel in the nozzle Another parameter, little studied elsewhere, is the depth of the suction channel in the nozzle. Given the characteristics of the product and especially the low power of the engine, good performance was obtained by gradually changing the depth of the channel from the edges to the center. The best results have been obtained when the suction channel has an increasing depth of the lateral edges towards the center, this depth being less than 2 mm at the edges, and between 5 and 8 mm towards the center, before the connection with the conduit.
  • the present invention finds its full application in combination with an electric waste recovery device type brush vacuum, comprising a frame inside which is housed in particular a motor, a waste separation device, said apparatus having a finished handle by a handle, and a nozzle connected to the frame of the vacuum cleaner by a tube, the latter being in a ventilation connection with the waste separation device, said nozzle having at least one of the characteristics mentioned above.
  • the electrical power of the motor of the apparatus is less than 500 W, the characteristics of the nozzle having been specifically studied for low power.
  • the vacuum cleaner 1 shown in FIG. 1 is of the broom type, and thus comprises a frame 2, extended upwards by a handle 4.
  • the frame contains, in a manner known per se, a motor 6, a waste separation device 10 Aeraulic connection with the engine.
  • the waste separation device is a dust bag, but an inertia or cyclonic separation device can be envisaged in the context of the present invention.
  • the separation device is housed in a removable compartment 12, to facilitate the cleaning or replacement of the waste separation device.
  • the motor can be powered by the mains or, preferably, using rechargeable batteries 8.
  • the power of the vacuum cleaner as shown and having batteries, is 300 W.
  • the start of the vacuum cleaner is ensured by a switch 14 preferably located near the handle 4.
  • the frame 2 is connected to a nozzle 20 via a pipe 16 in aeraulic connection with the waste separation device.
  • This tubing is connected to the nozzle by an elbow tube 18 hinged to the nozzle.
  • the nozzle 20 is symmetrical with respect to the x-x 'axis of the tube 18. It comprises a sole 26 clearly visible Figure 6, capped with a cover 24, on which are mounted four wheels 36 to facilitate the movement of the nozzle.
  • the sole has an opening directed towards the surface to be cleaned and constituting the suction channel 28, extending from one side edge to the other of the nozzle, being delimited by two front walls 38 and rear 39 forming the edges of the channel.
  • This channel is aeraulically connected to the elbow tube 18 by a pipe 29 visible in FIGS. 5 and 7, which opens into the suction channel through an opening 30, substantially in the middle of the suction channel.
  • the nozzle also comprises two tear strips 32 arranged on either side of the suction channel. Furthermore, a brush 34 extending substantially over the width of the nozzle, is arranged near the front edge of the nozzle.
  • the present invention relates primarily to the characteristics of the suction channel 28, in relation to the low power presented by the engine.
  • FIGS. 3 and 4 show the respective increase in the width of the channel. and its depth.
  • the width of the suction channel at the side edges of the nozzle, denoted 1 is of the order of 13 mm.
  • the width of this same channel, near the opening 30, marked L, is of the order of 22 mm.
  • this increase in the width of the suction channel is continuously progressive, by the arcuate shape of the front wall 38 of the channel, in particular to have better air flows in said channel.
  • the suction channel is more and more deep when one passes from one of the lateral edges of the nozzle to the central opening 30, by a progressive slope given to the wall. 40 delimiting the depth of the channel.
  • the opening is of the order of 2 mm, with a slight rise on the edges of about 1 mm, while near the opening 30, the depth of the suction channel denoted h is 6 mm.
  • the two walls 38, 39 are slightly prominent of the sole and provide a scraping effect on the ground before suction. This protrusion of the walls of the suction channel is clearly visible in FIG. 6.
  • the walls 38, 39 are situated at a distance of between 0.5 and 1 mm. from the ground, scraping thus occurring only on carpet-type floors where the wheels sink slightly into the ground.
  • nozzle Another particularity of the nozzle as shown relates to the scraper brush 34 disposed near the front edge of the nozzle, which has notches to alternate scraping areas 44 with openings 40, 42 constituting suction areas of large waste, central opening 42 being wider than the openings 40.
  • the passage of the nozzle on the floor not only solicits the soil to be cleaned, and in particular the fibers of the carpet-like floors, but also to aspire large waste by the openings 40, 42, waste that would be pushed by the brush in the absence of said openings.
