Definitions

  • the invention relates to a vacuum cleaner with centrifugal separator according to the preamble of claim 1.
  • the object of the invention is therefore to develop a centrifugal separator for a vacuum cleaner so that the vacuum cleaner of failures is preserved by blockages, but at the same time the manufacturing cost of the vacuum cleaner can not be increased.
  • At least one of the lateral surfaces of the cover or the wall of the centrifugal separator connectable to the cover is conical, whereby the circumference of the engaging lateral surface at least partially exceeds the inner diameter of the female part, so that the overlapping lateral surfaces of the interlocking parts when the cover is closed enter ring-shaped press connection. Due to the enlarged diameter of the inserted locking closure part, an extremely good seal is achieved, which ensures an airtight seal even without additional sealing means such as O-rings or the like. Due to the conical shape of one of the lateral surfaces, the introduction of the larger lateral surface is made possible on the one hand, but on the other hand causes this formation that the lateral surfaces do not contact surface but only in an annular line, which additionally causes an improved sealing function.
  • the detachable lid is provided as a closure for a centrifugal separator, which has a dust outlet through which the separated dust can be ejected into a separate collecting container.
  • the closed with the lid opening of such centrifugal separator is used exclusively cleaning purposes of the centrifugal separator, for example in the case of a blockage and must therefore be solved very rarely.
  • the lid must be easy to open, even if it has not been used for a long time, if any dirt particles have accumulated between the lid and the separator.
  • the invention is not limited to this type of centrifugal separators. Rather, it can also be used advantageously in centrifugal separators, in which the releasable lid must be opened in each case for the removal of the separated in the centrifugal separator dust and dirt. Again, it is of course necessary to provide a well sealed against the environment detachable lid, so that the invention is advantageously used.
  • the lid engages in the inner wall of the centrifugal separator or in a mounted on the inner wall of the centrifugal separator recording.
  • the centrifugal separator itself or an associated receptacle represents a particularly stable connection part, so that when inserting a circumferentially enlarged lid into the interior of centrifugal separator or recording a particularly good sealing connection is formed, since this counteracts enough resistance.
  • the invention in a centrifugal separator, in which the cover engages in the outer wall of the centrifugal separator and thus effectively slipped over the centrifugal separator.
  • the latter embodiment may be more advantageous, since the opening of the lid is simplified in this case, even if the sealing function may be somewhat reduced in this case.
  • actuating surfaces are advantageously provided on the lid, which protrude upwards as a handle for opening the lid and thus represent a suitable intervention for the hand.
  • these actuating surfaces are rounded so that they allow an optimal application of force of the hand, through which an opening of the lid can be easily made even after a long period of non-use.
  • both the wall of the lid in the region of engagement in the centrifugal separator and the wall, in which engages the lid so the wall of the centrifugal separator itself or an associated receptacle for the lid is conically shaped.
  • a meshing of the mating jacket walls is particularly simplified.
  • the lateral surfaces of the connecting part engaging in the interior are formed in the conically shaped area with respect to the outer peripheral lateral surfaces as a truncated cone of a cone with a larger opening angle.
  • the engaging further open truncated cone exerts pressure in this case during insertion and closing pressure against the surrounding outer surface, so that it is pressed to the outside, with a good seal between the surfaces is ensured.
  • the invention proves to be particularly advantageous when it is combined with a closure which is arranged separately from the region against which the two intermeshing lateral surfaces abut each other in a sealing manner.
  • a closure which is arranged separately from the region against which the two intermeshing lateral surfaces abut each other in a sealing manner.
  • a rotatable closure to the centrifugal separator.
  • a screw cap can also be provided with some leeway, which allows the interlocking surfaces to introduce deeper into each other after some wear, so that the sealing function is maintained even after wear.

  • the dust collection box 3 can be removed via a handle 4 separated from the centrifugal separator 2. In the inserted state, it is connected via a latching hook 5 with the lower part 1.

From the air inlet 11, the offset due to the inlet geometry, not shown in a vortex air flows in the vortex tube 13 of the centrifugal separator 2 to the lid 14 of the centrifugal separator 2 on the basis of the geometry of the molded cone 15 of the vortex and inside the vortex tube 13 in a dip tube sixteenth of the centrifugal separator 2 is introduced.
  • the purified air passes into an air outlet 17 through which it passes into the sucking vacuum chamber in the vacuum cleaner from which it is discharged to the environment.

  • Figure 5 shows a longitudinal section through the upper half of the vortex tube 13 with the molded receptacle 19 in which the lid 14 engages.
  • the seal forming connection of the inner wall 26, the receptacle 19 and outer wall 27 of the lid 14 can be seen.
  • the two jacket walls 26 and 27 are conically shaped.
  • the drawn on the right side of the connection angle 28 of the cone of the sealing portion of the lid 14 is about 7 ° and is thus significantly greater than the angle 29 of the receiving cone 19 of the vortex tube 13. Due to the larger angle of attack 28 of the engaging lid cone of the lid 14th exceeds the outer diameter of the lid 14 in the upper region of the lateral surface 27, the inner diameter of the receiving cone 19 in the region of the lateral surface 26. This has the consequence that the lid 14 presses the receiving cone 19 during insertion to the outside, wherein the lateral surfaces 26 and 27 due to However, touch differently inclined angles of attack only in an annular small area and thus form an optimally sealing surface.
  • the buttons 23 and 24 of the bayonet lock engage in the thread segments 22 and 25 of the lid and hold it firmly. Since the sealing connection of the jacket walls 26 and 27 is not in the region of the bayonet but above, the sealing effect is not affected by repeated opening of the lid and the associated wear of the closure.
