Definitions

  • the invention relates to a vacuum cleaner with a centrifugal separator according to the preamble of claim 1.
  • Such vacuum cleaners are known from various applications.
  • Components of such a vacuum cleaner are essentially one or more nozzles for sucking the dust, a suction pipe, which is designed depending on the structure of the vacuum cleaner as a floor, hand or upright sucker shorter or longer or rigid or flexible, one or more centrifugal ,
  • a dust container which may be part of the centrifugal or the centrifugal separator or is designed as a separate dust collector, a vacuum chamber through which the air is sucked by a fan, and optionally a fine dust filter for cleaning the outgoing air.
  • a generic vacuum cleaner is from the DE 100 21 594 A1 known.
  • the vacuum cleaner described there essentially comprises the usual components of a conventional vacuum cleaner.
  • the housing is formed by a lower shell and a dust chamber lid.
  • a dust box instead of the dust bag is a dust box, consisting of a centrifugal separator comprising a dip tube, a dust collection chamber and a filter.
  • a centrifugal separator comprising a dip tube, a dust collection chamber and a filter.
  • the invention has for its object to develop a vacuum cleaner with centrifugal separator, in which the structure of a conventional device can be largely adopted, without causing the dust collection space is unnecessarily limited.
  • the centrifugal separator is releasably connected to the housing of the vacuum cleaner.
  • the centrifugal separator preferably removably engages in the housing at the point at which the suction pipe is attached to a conventional predecessor model of the vacuum cleaner, which was equipped with a vacuum cleaner bag.
  • the centrifugal separator is effectively inserted between the housing and the suction pipe of a conventional vacuum cleaner. As a result, the previous structure of the conventional vacuum cleaner can be used without conversion measures.
  • the centrifugal separator is releasably secured by means of a connecting piece on the housing.
  • This allows the attachment of the suction pipe for the conventional vacuum cleaner in principle without changes as attachment for the mounting of the centrifugal separator are taken.
  • the proven for the suction pipe of a conventional vacuum cleaner technology is thus used here for the centrifugal separator and the subsequent intake manifold. This can severely limit the development and design costs. A always problematic in new constructions error prone can be avoided.
  • connecting piece is fastened via a latching connection in the housing.
  • a locking connection is easily solvable in the event of a blockage for troubleshooting, so that the centrifugal separator can be removed easily at any time in this case without the use of tools.
  • Another advantage of the locking connection is that no threads or other connecting elements are provided on the housing, so that the housing can be very easily constructed.
  • a joint is provided on the connecting piece, which serves to guide the pivoting movement of the centrifugal separator.
  • the centrifugal separator is stably stored and can still be pivoted away for removing a dust box located below it, so that the centrifugal separator does not have to be removed from the housing to remove the dust box each time.
  • a flexible connecting element such as a flexible tube is provided between the housing and the centrifugal separator.
  • this flexible connecting element ensures the air flow for the purified air discharged by the centrifugal separator and, on the other hand, gives the centrifugal separator the necessary freedom despite bearing on the housing to carry out the pivoting movement to the extent necessary for removing the dust box.
  • This connecting element is preferably designed as a spiral tube.
  • a spiral tube By means of a spiral tube, the necessary stability can be ensured at the same time which prevents the centrifugal separator from hanging down from the housing and, at the same time, mobility is provided on a large scale.
  • the flexible connecting element is guided in a joint, which preferably has stops for restricting the pivoting movement. This ensures that a controlled pivoting movement is performed while keeping the load on the flexible element as low as possible.
  • the joint is realized by means of a slotted guide. This can cause a very controlled, little material claiming pivotal movement of the centrifugal separator.
  • a spring preferably a leg spring, is arranged on the joint, which causes the centrifugal separator to pivot automatically into the removal position for the dust box. This allows the vacuum cleaner to be made more user-friendly, since it is not necessary at the same time to keep the centrifugal separator away when the dust box is to be removed.
  • the flexible connecting element itself is resilient, so that this causes the automatic pivoting of the centrifugal separator in the removal position for the dust box.
  • an additional spring is unnecessary, the joint itself can be made simpler.
  • the connecting element is designed as a spiral hose with an integrated metal spring.
  • an afflicted with a restoring elastic connection between the housing and centrifugal separator is realized particularly cost-effective and stable.
  • the centrifugal separator In order to hold the centrifugal separator in its working position on the housing against a possible restoring force, the centrifugal separator is constructed on its side opposite the connecting element housing side so that it engages in a connection provided on the housing handle and is fixable there.
  • a mounted on the housing handle connection for fixing the centrifugal separator can be very user-friendly for the removal of the dust box by means of a simple Release button can be released as soon as the operator has his hand on the handle of the vacuum cleaner.
  • FIG. 1 shows a section through a vacuum cleaner 5 according to the invention with centrifugal separator 1, which is connected via a connecting hose 2 with the housing 4 of the vacuum cleaner 5 removably attached hose nozzle 3.
  • the hose nozzle 3 engages via a latching connection in the housing 4 of the vacuum cleaner 5, so that it can be detached, if it comes in the connection area between centrifugal 1 and 5 vacuum cleaner to blockage. As a result, a frequent failure of the vacuum cleaner 5 can be avoided.
  • the trained on the vacuum cleaner 5 receptacle for the hose nozzle 3 is formed as well as the receptacle for the hose nozzle of the suction pipe of a conventional dust bag vacuum cleaner.
  • the centrifugal separator 1 is pivotally mounted about the pivot point, so that it can be pivoted away from the vacuum cleaner 5 in a range of about 90 ° for removing the vacuum cleaner located below it in the 5 separate dust box.
  • the fulcrum is located in an axis which is part of a hinge 6 which can not be represented in this sectional view.
  • this joint 6 which stabilizes the connection between the detachable hose nozzle 3 and the centrifugal separator 1, the connecting hose 2 is guided during the pivoting movement.
  • the joint 6 is equipped with a slotted guide.
  • In addition to the air outlet region 7 is airtight separated from this the air inlet region 9 of the centrifugal separator 1.
  • the air vortex flowing from the air inlet 9 through the vortex tube 12 to the opposite end is deflected into the interior of the centrifugal separator 1 to the dip tube 8 back.
  • the deflected air vortex is discharged via the air outlet 7 to the vacuum cleaner 5.
  • a dirt discharge 16 which is designed as an opening in the vortex tube 12.
  • the separated from the turbulent air via centrifugal dust is discharged to a separate dust collection container, not shown, which is located in the vacuum cleaner 5.
  • the suction pipe 11 connected via the connection piece 10 to the centrifugal separator 1 enters the centrifugal separator 1 in a straight line.
  • the inflowing air is guided in a straight line past the unavoidable edges resulting from the connection between the suction pipe 11 and the separator 1, so that there is no potential for setting larger dust particles entrained in the air. Turbulence caused by the air deflection and can cause blockages when passing such edges, arise only in the interior of the vortex tube 12, where no edges occur.
  • the air in the lower region of the air inlet 9 is deflected by means of a formed in the air inlet region 9 in the interior of the vortex tube 12 Archimedean screw.
  • the centrifugal separator 1 is a in the FIGS. 2 and 3 Detent connection 19 shown in detail held on the handle 17 of the vacuum cleaner 5.
  • the handle 17 has a release button 18, which must be pressed to release the locking connection 19 down.
  • the release button 18 is pressed, the latching tongue 19 is pushed away from the cover 13, in which it engages in the closed state, and thus releases the centrifugal separator 1.
  • the connecting hose 2 between centrifugal separator 1 and hose nozzle 3 is as a spiral hose with an integrated metallic Spiral spring is formed and thus has intrinsic restoring force, which lifts the centrifugal separator 1 from the vacuum cleaner 5 and in an occupied by about 90 to the in the working position in the FIG. 1 pivoted position shown.
  • This joint 6 also has a non-visible in the sectional view stop which defines the rest position of the centrifugal separator 1, in which the centrifugal separator is approximately perpendicular to the vacuum cleaner 5 and a not shown stored inside the vacuum cleaner 5 dust box for removal releases.
  • the dust box is released for emptying by the user actuates the release button 18 on the handle 17.
  • the unfolding of the centrifugal separator 1 thus takes place automatically by releasing the release button 18, without any further manipulation of the user would be necessary.
  • the FIGS. 2 and 3 show the set by pressing the release button 18 in progress mechanism for opening the locking connection 19 again in detail in the closed or opened state.
