Definitions

  • the invention refers to a cleaning apparatus, consisting of brushes and suction openings adjacent to these brushes, which are attached to a suction device, in particular a vacuum cleaner.
  • a suction device in particular a vacuum cleaner.
  • only a part of the nozzle of the vacuum cleaner is fitted with tufts of bristles, while the remaining part is provided with suction openings, between which there are individual webs which serve to support the relatively thin wall of the brush unit.
  • a further development of the basic idea of this invention consists of the following: proceeding from the main fitting of the vacuum cleaner with tufts of bristles, which are mainly placed on one side, individualtufts of bristles, in the shape of projecting transverse rows or in projecting clusters or wedge-shaped arrangements, are placed at suitable locations outside of the suction slits, in particular at the border areas and in the areas of the webs which have been provided.
  • These tufts o'f bristles have the same length as the tufts of bristles of the main fitting, and have the purpose of providing firm guidance as the nozzle unit glides over the surface to be cleaned, and in particular that of preventing tilting or canting.
  • the dirt also includes fluid and gummy ingredientg' such as oils, waxes, greases and the like, which during to a suction device, in particular a vacuum cleaner.
  • fluid and gummy ingredientg' such as oils, waxes, greases and the like, which during to a suction device, in particular a vacuum cleaner.
  • a vacuum cleaner is especially suitable for removing the fine dust or it is particularly effective when it is necessary to move larger and heavier types of dirt into the in- I terior of the suction nozzle with adequate dependability and speed.
  • suction slits which open at a very small distance of one or only a few millimeters above the surface to be cleaned, and in addition other suction slits which open at a considerably greater dis high specific weight, such as fine metal particles, rnetal dust, filings, paper clips, pins andthe like are certain to be sucked inas a result of the high speed and strong suction from the suction slits opening close to the floor.
  • Coarser matter such as paper scraps, cigarette butts and the like,which to be sure are relatively bulky in their dimensions but are relatively light because of the'low specific weight of the material of which they are-made, are not, it is true, sucked. in by the nozzle slits which open close to the floor, since they are pushed aheadof thecle aner' by the walls of the nozzle slits'. But these bulky items'can b'e sucked in by the other nozzle -openings which open at a substantially greater distance from the surface to be cleaned. Furthermorq'it is expedient to make the dimensions of these nozzles bigger and to make their air flow channels wider and broader, so that these bulky items really get sucked in and do not get stuck in the interior of the channels.
  • suction nozzles are also intended to be used to remove dirt and dust from the corners of rooms and from other places to which access is relatively diflicult, and since it has been established that dust and dirt cling relatively stubbornly to these corners and cannot be removed without difficulty, it can be of advantage to make the nozzles in such a way that the suction power for use in corners is particularly strong.
  • the suction opening are given a very special shape; care is taken so that the distance between the nozzle opening and the floor is not uniform along the entire length of the nozzle slit, but reaches a minimum in the direction of the narrow side of the nozzle unit.
  • Fig. l is a bottom plan view of a cleaning apparatus provided with narrow slits along one longitudinal edge and with relatively broad slits along the other longitu dinal edge of the apparatus;
  • Fig. 2 is a transverse sectional view through the apparatus taken along the line 2-2 in Fig. 4;
  • Fig. 3 is a transverse sectional view taken along line 3-3 in Fig. 4 and being drawn in an enlarged scale;
  • Fig. 4 is a front elevational view of the cleaning appaslits and are disposed in forward to rearward alignment with the suction channels 20, 22 and 24. It is noted that the suction channels 20,22 and 24 are of relatively large area and that the slits 46, 48 and 50 are arranged transversely to the forward direction of the movement of the body.
  • A'nozzle for a vacuum cleaner device comprising a body with a working face having a forward leading edge
  • said body having a plurality of aligned elongated suction channels therein positioned in spaced apart relation to each other defining webs therebetween and extending through said working face and located rearwardly of said forward leading edge of said body, said webs having recesses therein, said body having a groove therein, a main bristle unit received in said groove and including bristle tufts located forwardly of said suction channels and extending transversely to the direction of normal movement of said body, auxiliary tufts of bristles located rearwardly of and contiguous to said forwardly located tufts of bris- 1
  • the body is provided with a plurarity of aligned elongated suction channels as are indicated at 20, 22 and 24, respectively, positioned in spaced apart relation to each other defining webs as at 26 and 28 therebetween.
  • suction channels 20, 22' and 24 are located rearwardly of the forward leading edge 16 of the 1 body.
  • the webs have recesses therein as indicated at 30 and 32, respectively, which recesses communicate with the groove 34 in the body.
  • a main bristle unit 36 is received in the groove 34 and includes bristle tufts 38 located forwardly of the suction channels 20, 22 and nozzle 10 when the nozzle is moved over a surface to be cleaned and prevents canting while offering simultaneously a substantially unobstructed suction effect through the suction channels 20, 22 and 24.
  • the working face 14 is provided with a group of suction openings 46, 48 and 50, which are relatively elongated to form tles and in said recesses in said webs between said suction channels, said auxiliary tufts of bristles being of substantially the same length as that of said forwardly located tufts'of bristles to provide effective guidance for said nozzle when same is moved over a surface to be cleaned andfpreventing'canting while offering simultaneously a substantially unobstructed suction effect through said suction channels, said working face being provided with a group of suction openings adjacent said leading edge, said suction openings being relatively elongated to form slits and disposed in forward to rearward alignment with said suction channels of relatively large area, at least one of said slits 'being arranged transversely to the forward direction of movement of said body.
