Definitions

  • This invention relates to a device in vac uum cleaners and the like, and its object is to provide a vacuum cleaner which cleans the F surface or object to be treated in an effective way,
  • Another object of the invention is to provide a vacuum cleaner with an agitating device which is continuously rotated on account of the pressure difference between the interior and exterior of the cleaner.
  • a further object of the invention is to provide a. vacuum cleaner, in which the shaft of the agitating device is located nearer to one of the longitudinal edges or working edges of the suction pipe than to the other.
  • FIG. 1 is a diagrammatic view of a vacuum cleaner of any construct-ion, said vacuum cleaner being provided with a deviceaccording to the invention.
  • Figure 2 represents a vertical section, in detail, of the cleaning device, part of the box being broken away.
  • Figure 3 represents a vertical section, corresponding to Figure 2 showing a modified form of box.
  • Figure 4 represents in detail a modification of the beating element shown in Figure 2.
  • Figure 5 represents a top plan view of the cleaning device as a whole.
  • the vacuum cleaner is indicated by 1 and may be of any type as mentioned above.
  • the suction pipe 2 which according to the invention is coupled to a cleaning device 0 consisting of a box having a plane lower side or bottom 4.
  • the lnsertlon opening for the suction pipe 2 is indicated by 5.
  • an agitating device which is journalled in such a way that it may be automatically brought to rotate during the operation on account of the pressure difference between the interior and the exterior of the cleaner.
  • the shaft 6 is provided with a number of beating elements 13, which may consist of a yielding material, for instance paper, pasteboard or the like.
  • the fore edges of the beating elements may be provided with reinforcing strips 14 or the like.
  • This device is clearly shown in Figure 4E and the object of the same is to cause increased friction between the beating elements and the object to be cleaned.
  • This embodiment is further characterized therein that one of the working edges, viz. 7, of the suction pipe or box 3 is located at a certain distance from the plane working surface or bottom 4 of the box 3, the turning y axis of the shaft 6 being located nearer to this ed e 7 than to the other workingedge 8. It thus results that the beating elements 13 will beat and drag against the object to be cleaned, and further that, the beating elements on the side toward the working edge 8 extend relatively far from the revolving shaft.
  • the mode of'operation of the device is as 1 follows: than the vacuum cleaner is started, there is is a reduction in pressure in the suction pipe or box 3, which results in the total pressure on the beating elements be tween the shaft 6 and the working edge 8 becoming considerably greater than the total pressure on the beating elements between the shaft 6 and the edge 7. lhus, the shaft 6 will be rotated automatically in the direction of I the arrow 12 ( Figure 2). It is evident that the rotation of the agitating device results in a beating of the carpet, or the like, being treated, and that thus a very effective cleaning action will result.
  • the shaft is journalled with its journals 19 in the material of the suction pipe;
  • T he side walls of the box may for this purpose on one or on both sides be provided with slits or guiding grooves 20 open towards the mouth of the suction pipe, the agitating device being held in position in the slits or grooves on-account'of the resilient'pressure of the beating elements against the edge 7 located closer to the journals 19;
  • the agitating device may by reason of this arrangement be easily taken'out or inserted' in the box 3 bya single manipulation.
  • a suction pipe having a working opening, a retary agitating means located in, and substantially' filling said' opening, said agitating means having an axial shaft located nearer to one of the longitudinal edges of the working opening than to the other, and an operative portion of theagitating means extendin g normally outside of the working opening of the suction pipe, whereby-the"agitating means may be automatically rotateddur ing the operation of the cleaner on account of the pressure difference between the interior and exterior of the cleaner.- 1 i 2.
  • the agitating means included'esbeating elemerits-mounted parallel to the axis, said elements extending at their points of attachment tangentially from their supporting bOdy.
  • a device in which the agitating means includes beating elements of resilient material mounted parallel to the axis, said elements extending at their points of attachment tangentially from their supporting body: and being provided with reinforcing strips adjacent thei-router edges.
  • a device in which the bottom surface of the suction pipe is formed as a plane adapted to rest against the object to be cleaned, one edge of thezworking opening beinglocated at a distance from said plane surface, and said agitating means being mounted closer to said edgethan tothe plane surfacta a.
  • a device in which the side walls of the device are extended beyond the edges of the working opening and adjacent the sides of the agitating means, whereby they serve to cover the greater part of the sides of said means, said side walls having their lower edges curved upward from the lower edge of the working openin 7
  • the side walls otthe device are extended beyond the edges of the working opening and adjacent the sides of the agitating means, whereby they serve to cover the greater part of the sides of said means, said side walls having their lower edges curved upward from the lower edge of the working opening, said upwardly curved portions being formed as separate pieces pivotally securedto' the side walls, whereby a continuous close-com tact with the material being cleaned is ensured.
