Definitions

  • the present invention relates to a vacuum cleaner for carpets and rugs, dry hard floors and wet hard floors.
  • a first known type of nozzle comprises on the one hand, a housing provided with a suction tube and forming a body with a sole which delimits between pads at least one channel communicating by at least one passage with said tube and, on the other hand, a mobile plate fitted with a brush passing through a slot made between the sole and the housing, plate which is controlled by an actuating device placing it in the high position for cleaning carpets or rugs or in the low position for cleaning hard floors.
  • This known nozzle is not designed for cleaning hard wet floors, but only for cleaning dry hard floors: tiles, tiles, parquet ... so that the brush generally extends around the entire periphery of the sole. and moves with the mobile stage, to rest on the ground in the low position and be retracted in the high position.
  • a second known type of nozzle is described in European patent application No. 0 158 145. It comprises a housing integral with a bent duct, the rear upper end of which is connected to a suction pipe and the lower end of which is median opens through an opening in a transverse suction channel from below the housing. Two brushes extending parallel to this channel are guided in vertical translation on either side of the bent conduit and are moved by a transverse slide to occupy several positions. The slide guided in horizontal translation in the housing can be moved, to select the position of the brushes, by the user. To this end, it acts on a pusher of said slide which passes through the housing and projects outside.
  • a flexible blade is fixed under the housing between the brushes to come into contact with the ground or a carpet when the brushes are retracted or in low projection, the blade having the function of increasing the speed of the air at l entry of the squeegee.
  • the present invention aims at this object by perfecting the nozzle of the first type.
  • a scraper device made of flexible material is mounted on the plate on the side of the channel opposite to that where there is a straight part of the brush, the scraper device extending parallel to the brush to a level located slightly below that of said brush so that, the plate being in the low position, the device flexes in the direction opposite to that of the displacement of the squeegee and delimits passages through which the water which is not scraped travels.
  • the rectilinear brush, front or rear, is extended by lateral parts to form a U-shaped brush.
  • the scraper device is located at the rear of the channel and consists of a monolithic blade having recessed on the rear face of the vertical grooves which open downward, as well as forward to let the water pass when the squeegee is pulled back with the plate in the low position, the blade is laid forward and rests on the ground, delimiting passages through the ridges of ribs separating the grooves.
  • the blade is inclined downward and forward.
  • the scraper device whether located at the rear or at the front of the channel, consists of two alignments of flaps parallel to each other, the flaps of an alignment being separated from each other by passages located opposite flaps of the other alignment so that the "wave” scraped on the ground by the flaps in forward direction is swallowed by the suction channel without the possibility of s escape backwards in staggered passages, while the "wave” scraped on the ground in reverse is sucked forward by said channel through said passages staggered.
  • the lower edge of the scraper device extends at or above the sliding plane of the sole and at a short distance.
  • the squeegee comprises a housing 1 made of plastic forming a body, at its upper rear part, with a sleeve 2 in which a suction tube 3 is mounted to rotate with sealing around an axis substantially horizontal anteroposterior.
  • This tubing 32 opens into a chimney 4 communicating, through a passage 5, with a channel 6 of a metal sole 7 fixed in the housing 1.
  • This sole is intended to slide on the ground by pads 8 delimiting between them the channel 6 cited above.
  • the housing 1 can be integral with the suction tube 3 or it can be rotatably mounted relative to the housing around not only an anteroposterior axis but also a transverse axis.
  • the squeegee can cooperate with a rear support roller and more particularly it can be of the floating type described in French patent No. 2,546,054.
  • the housing 1 contains, above the sole 7, a plate 9 capable of occupying two positions illustrated by FIGS. 3 and 4.
  • the plate 9 is held in the high position, called the retracted retracted position (FIG. 3), by conical helical springs 10 interposed between the sole 7 and itself, these springs being threaded on rods 11 for guiding said plate in vertical translation, allowing it to move parallel to itself.
  • the plate 9 is controlled in translation towards the low position called the intervention output position (FIG. 4) and locked in this position, by end pins 12 of a transmission rod 13 passing through levers 15 of two actuating pedals 16 , 17 articulated by means of pivots 18 in the housing.
  • the pins 12 bear directly on inclined ramps 14 integral with the plate 9 and ending in high notches 19 for locking.
  • a peripheral slot 20 is formed between the sole 7 and the housing 1 for the passage of cleaning members on hard ground.
  • These members include a linear brush 21 called “strip" which, in the example shown, is shaped like a U; it has a facial part 22 extending in front of the channel 6 and extended by lateral parts 23, 24.
  • the bristles of this brush 21 are fixed in a frame 25 inserted in a slide 26 of the plate 9.
  • the cleaning members comprise, in addition to the brush 21, a scraper device 27 constituted by a flexible material such as a rubber or other elastomer.
  • This device extends parallel to the facial part 22 of the brush 21 and is located on the other side of the channel 6.
  • the scraper device 27 is integral with a strip 28 inserted in the slide 26 of the plate 9.
  • the part 22 of the brush is located at the front and the scraper device 27 at the rear.
  • This scraper device consists of a monolithic blade 29 having in hollow, facing the rear, vertical grooves 30 separated by ribs 31 profiled in V. The grooves open at the bottom.
  • the free edge 32 of the blade 29 at rest is located at a slightly lower level than that of the brush 21.
  • d can be between 1 and 4 mm, while D is between 5 and 8 mm.
  • the blade 29 at rest instead of being vertical, is tilted down and forward when at rest. This inclination makes it possible to favor the curving of the blade in reverse so as not to scrape the water and to stiffen the curved blade in forward to better scrape the water.
  • the part 22 of the brush is always located at the front and the scraper device 27 at the rear.
  • This scraper device comprises two substantially parallel alignments of flaps 35 and 36 forming one body with the strip 28 mounted in the plate.
  • the flaps 35 are separated from each other by passages 37 and the flaps 36 by passages 38.
  • the flaps 36 of the second alignment are located opposite the passages 37 of the first alignment. Consequently, the passages 37 and 38 are distributed in a staggered fashion and communicate with each other by the passage 39 formed between the two alignments.
  • the flaps 35, 36 and the strip 28 are relatively stiff.
  • the front and rear faces of these flaps are flat.
  • the lower edges of said flaps are rectilinear and situated at a level slightly lower than that of the brush 21; however, the distance "e" ( Figure 5) of these levels is reduced so that the flaps 35, 36 barely bend when moving the squeegee in forward or reverse; it can even be zero.
  • This type of device scrapes and draws water in both directions.
  • the staggered arrangement of the flaps and passages makes it possible to scrape the water off the ground and to remove it, when the nozzle is pulled or pushed, in a straight line or in a zig-zag, because that the suction combines its effects with the scraping flaps thanks to the presence of the passages through which the said suction intervenes.
  • a third embodiment illustrated in FIG. 7 is applicable in particular to the floating nozzle which is the subject of French patent n ° 2.546.054.
  • This nozzle is identical to that described with reference to Figures 1 to 5, with the only differences that the housing 1 is not integral in this case with the sleeve 2.
  • a tilting nozzle 40 is pivotally mounted around a transverse axis 41 of the housing and its internal conduit 42 opens into the chimney 4.
  • the sleeve 2 in which the suction pipe 3 is mounted to rotate about an anteroposterior longitudinal axis is pivotally mounted on the tilting nozzle 40 around a transverse axis 43 located between the aforementioned axis 41 and an axis 44 around which a roller 45 is mounted to rotate.
  • the axis 44 is carried by the nozzle 40 behind the housing 1 and at the bottom.
  • the housing 1, the sole 7, the plate 9, the brush 21 and the squeegee 27 form a floating assembly.
  • the brush 21 shaped into a U is symmetrical to the previous one, since its facial part 22 is now located at the rear. Consequently, the scraper device 27 with flaps 35, 36 and staggered passages 37, 38, 39 is mounted in the plate 9 at the front; it operates in the same way as set forth in the above for the second embodiment. It also has the advantage of being sensitive to maneuverability.
  • the scraper device 27 can be used as a thread puller, provided however that its lower edge is located at low distance and above the sliding plane 33 of the sole 7. This distance d is advantageously between 1 and 3 mm.
