Definitions

  • the invention relates to an electric suction brush for a vacuum cleaner according to the preamble of claim 1.
  • Such electric suction brushes are known per se and have a housing, an electric motor, an intake manifold connection piece, a brush driven by the electric motor, a suction air guide, and a swivel joint arranged in the area of the intake pipe connection piece.
  • the intake manifold connection piece and thus the connected intake manifold can be tilted about an axis lying essentially parallel to the rear edge of the housing and simultaneously rotated about its central axis.
  • the electric motor of an electric suction brush is always on one side of the longitudinal central axis of the brush, so that the electric suction brush always turns to the side on which the electric motor is raised when it reaches a corresponding tilt angle between the suction tube and the brush is arranged.
  • This movement is made possible by the tilt and turn joint and is quite desirable when the brush is in operation on the ground, but it makes handling when lifting the brush disadvantageous.
  • the organization system essentially consists of a catch arranged either on the suction pipe or on the vacuum cleaner housing, which can be inserted into a groove in a guide rail.
  • a counterweight could be attached in the electric suction brush on the side opposite the electric motor, so that the electric suction brush is in equilibrium even after lifting up to the tube axis.
  • This solution initially has the disadvantage that the electric suction brush is overall heavier and therefore more unwieldy, and additional materials have to be used which further increase the production and assembly costs.
  • latching devices could also be incorporated in the rotary tilt joint, which, however, has the disadvantage that this latching would have to be latched on every time during normal work, which makes the work unpleasant and also causes a noise. Furthermore, the production and assembly costs are also increased here.
  • the invention is therefore based on the object of developing an electric suction brush according to the preamble in such a way that lateral turning of the electric suction brush when lifting is reduced or avoided due to the uneven weight distribution such that suction is not impaired even when the suction brush is briefly raised in the meantime, or a twisting off of the freely suspended or raised suction brush is limited, so that the disadvantages mentioned in connection with the use of an organization system do not occur without the production and assembly costs being increased disproportionately.
  • the housing bushing for the rotary tilt joint or the intake manifold connection piece is narrowed downwards in such a way that, when the tilt angle increases, the rotating part of the rotary tilt joint or pipe connection piece comes to rest there and its ability to rotate is therefore braked.
  • the angle of tilt between the suction pipe and the brush increases.
  • the rear edge of the brush lifts off the floor and still lies on the front edge, while the tilt angle increases.
  • Due to the narrowing of the housing bushing in its lower area the tilt and turn joint or the intake manifold connection piece comes into contact with the housing bushing from a certain tilting angle and its ability to rotate is thus braked. In this way, the brush can be advantageously lifted off the ground without immediately turning away to one side due to the uneven weight distribution.
  • the ability to turn can be influenced by an appropriate design of the braking device or the surfaces or parts that come into contact with it, or tilt and swivel parts.
  • the braking device could act non-positively in that surfaces come into contact with one another so that a certain, albeit greatly reduced, ability to turn is retained, or work in a form-fitting manner, e.g. Interlocking gears that do not allow any further turning ability.
  • This particularly simple, advantageous embodiment makes it possible to prevent the brush from turning away immediately when it is lifted off, without unnecessarily increasing the production and assembly costs.
  • the narrowing of the housing bushing consists of at least one cam which is arranged in the lower region on the housing bushing.
  • a cam can also be provided on both sides of the housing bushing in the lower region thereof, which improves the functionality for a long period of time.
  • the cams can have a substantially tetrahedral shape, so that when the tilt angle is increased, the contact surface is enlarged.
  • cams in one piece with the housing, i.e. to train them at the same time as the housing production. They can be designed as an injection molded part, so that they can be easily sprayed onto the housing during production.
  • the rib is advantageously formed by a rounded portion on the flanks, which can be latched on by the associated cam, on the outer circumference of the rotatable intake manifold nozzle. In extreme operating positions of the intake manifold, it is therefore guaranteed that the maximum angle of rotation of the tilt and swivel joint can be used.
  • An electric suction brush 1 has, in a manner known per se, a housing 2 which has a cover 3 on its upper side. At the rear of the housing 2 there is an opening 4, which serves for the implementation of a swivel-tilt joint 5 or an intake manifold connection piece 6. In the intake manifold connector 6, the intake manifold 7 is used in a known manner.
  • the tilt and turn joint allows the intake manifold connection piece 6 or the tilt and turn joint 5 to be tilted about an axis essentially parallel to the rear edge of the housing, i.e. a tilting up and down, as indicated by the double arrow 8, until the intake manifold connection piece strikes the lead-through edges. Furthermore, the tilt and turn joint enables rotation about the center axis of the intake manifold, as indicated by the double arrow 9.
  • Such electric suction brushes are usually equipped with rollers 11 which improve the usability of the brush.
  • a bushing constriction 12 which is shown in FIG Embodiment is formed by two cams 10.
  • These cams can be integrally formed with the rear wall of the housing, molded, tetrahedral elements, which cause that when the intake manifold connection piece 6 is tilted downwards, it comes into contact with the cams 10 and is thus considerably impeded in its freedom of rotation 9.
  • the arrangement of the cams 10 on the housing 2 is chosen in relation to the arrangement of the housing stop 13 on the cylindrical portion 14 of the tilting part of the rotary tilt joint 5, that the outside of the intake manifold connection piece 6 first comes into contact with the cams 10 before the stop 13th bears against the housing 2 to limit the tilting movement.
  • a rib 15 is provided on the outside of the cylinder of the rotary connector 16, against which the right cam 10 comes to rest when, for example, the electric suction brush 1 with respect to Fig. 2 with the cylinder held 16 rotated counterclockwise.
  • the rotary movement at a certain tilting position - as occurs, for example, when attaching the electric suction brush by means of the suction pipe 7 to the vacuum cleaner - is limited to a certain maximum value, so that it is avoided that the electric suction brush 1 has a corner over the lower edge of the vertical canister to be turned off protrudes.
  • the rib 15 is designed to be relatively short and is only in the path of movement of the cams 10 when the rotary tilt joint 5 assumes the corresponding tilt angle.
  • the flanks of the rib 15 are rounded so that the rib can be locked by the cams if this is required in extreme operating positions of the suction brush in order to utilize the maximum angle of rotation. This can e.g. occur when vacuuming under furniture.
