Definitions

  • the invention relates to a vacuum cleaner, in particular a hand-held vacuum cleaner, with a housing which provides a dust collecting space, and a Staubabscheide observed which is arranged in the dust collecting space.
  • Vacuum cleaners in general and hand vacuum cleaners in particular are well known from the prior art, which is why it does not require a separate documentary evidence at this point.
  • a generic vacuum cleaner typically has a suction fan, which generates a suction air flow in the intended use case. This arrives via an inlet opening in the dust collecting space provided by the housing. There it passes the Staubabscheide founded which retains the suction flow with transported dust particles, impurities and / or the like dirt. The suction air stream cleaned to this extent continues to pass through the pressure-generating blower and then leaves the housing via corresponding blow-off openings.
  • a vacuum cleaner of the type mentioned is proposed with the invention, which is characterized in that the Staubabscheide noticed is rotatable about an axis of rotation.
  • Staubabscheide which can be rotated about an axis of rotation.
  • a twisting movement results in a cleaning of Staubabscheide Surprise characterized in that thereto adhering dust particles, impurities and / or the like dirt are thrown off by the centrifugal force induced as a result of the rotational movement.
  • These thrown-off soiling remain in the dust collection room and can be taken care of at a next emptying of the dust collection room.
  • the rotatably rotatable arrangement of Staubabscheide nails makes it possible to dispense with a manual removal for the purpose of cleaning the user side. Without it being necessary to remove the dust removal device, the dust removal device can be cleaned on the user side by moving it around its axis of rotation in rotational movement.
  • the embodiment of the invention makes it possible on the user side in a simple and comfortable way to be able to effect a cleaning of Staubabscheide Surprise, without prior removal from the housing.
  • a cleaning can be carried out, for example, by a simple push of a button before and / or after each vacuuming, so that there is always a cleaned Staubabscheide overlooked with the aim of optimized suction.
  • the Staubabscheide perceived is designed to be displaceable in the longitudinal direction of its axis of rotation according to a further feature of the invention.
  • the Staubabscheide wisdom can therefore be moved from a first position to a second position and vice versa.
  • the Staubabscheidevoriques is in its first position in the so-called suction position in which a normal operation of the vacuum cleaner is permitted.
  • the Staubabscheide listening is in its cleaning position, in which already as described above, a cleaning of Staubabscheide driving can be performed.
  • the Staubabscheide has according to a further feature of the invention on a turbine blading.
  • This turbine blading serves to be able to set the Staubabscheide raised in rotary motion, if the Staubabscheide overlooked is in its cleaning position.
  • the Staubabscheide In order to put the Staubabscheide Published in a rotational rotational movement for the purpose of cleaning, it requires the inventive construction according to no additional motor support. Rather, the suction air flow generated in any case by the suction fan during operation is used to set the dust removal device in rotation for the purpose of cleaning. For this reason, the Staubabscheide accent has a turbine blading, which causes a corresponding rotational movement of the Staubabscheide recognized in the case of flowing past a suction air flow. In an alternative embodiment, however, it is also conceivable to arrange an additional motor element which sets the dust removal device in rotation.
  • the turbine blading is immersed in a first feature of the invention in the first position of the Staubabscheide observed in a housing provided by the housing receiving space. In the suction position, that is, in the first position of the Staubabscheide owned the turbine blading is therefore not in operative connection with the suction air flow generated by the suction fan.
  • the turbine blading is arranged within the space provided for this purpose and sucked by the suction fan suction air is passed through the Staubabscheide arthritis.
  • the Staubabscheide is held in accordance with a further feature of the invention under Federkraftbeetzschlagung in its first position. So far as no manual transfer of Staubabscheide annoying from the suction position takes place in the cleaning position, the Staubabscheide coupled is in the suction position, which is accomplished by means of a force acting on the Staubabscheide coupled compression spring. To transfer the Staubabscheide issued from the suction position in the cleaning position, the Staubabscheide responded against the spring force acting on it to move axially, which is on the user side to accomplish by means of a corresponding actuator.
  • the Staubabscheide has a bottom plate on the one hand and a cover on the other.
  • the lid and the bottom plate are spaced from each other and take between them a cylindrical filter element with a formed from a filter material jacket body.
  • the turbine blading is arranged on the bottom plate, so that an automatic immersion of the turbine blading takes place in the receiving space when the Steuerabscheide coupled spring loaded in their first position, that is, the suction position is spent.
  • an actuating element for manually transferring the Staubabscheide issued from its first position to the second position.
  • This actuator is the user side accessible from the outside, that is without prior opening of the housing and / or the dust collection chamber.
  • the actuating element is preferably a sliding element which acts on the dust removal device with the interposition of a linkage.
  • a space adjacent to the dust collecting additional space is provided, wherein the dust collecting space merges with the interposition of a passage opening in the intermediate space.
  • the Staubabscheide worn is longitudinally displaceable within this passage opening, wherein in the manner described above, the Staubabscheide recognized from a suction position in a cleaning position and vice versa can be transferred.
  • the peculiarity of the alternative embodiment consists in the fact that air openings are formed in the additional space bounding wall of the housing, so that fresh air can be sucked from the outside directly through the air openings in the wall of the housing at a befindliches in cleaning position Staubabscheidevorraum.
  • the particular advantage of this alternative embodiment is that not a suction air flow, but a fresh air flow is used to put the Staubabscheide worn in a corresponding rotational movement, so that on the introduced in the housing vents not a dust-laden air outlet, but rather a fresh air outlet ,
  • FIGS. 1 and 2 show in each case an alternative embodiment, the vacuum cleaner 1 according to the invention, wherein in the figures respectively above the axis 20, the so-called “suction position” and below the axis of rotation 20, the so-called “cleaning position” is shown.
  • the vacuum cleaner 1 has a housing 2. This is divided by a partition wall 3 into two areas, wherein the one area is formed by the dust collecting space 4 and the other area by the fan chamber 5.
  • the fan chamber 5 serves to receive a suction fan 6, which has a known manner via an electric motor 7 and an impeller 8.
  • a Staubabscheide noticed 9 is arranged within the dust collecting space 4. This has a top plate 11 and a bottom plate 10, between which an annular filter fabric 12 extends. Overall, the Staubabscheide noticed 9 is rotationally symmetrical to the axis of rotation 20 is formed.
  • the Staubabscheide overlooked 9 is freely rotatably mounted on a shaft 13 about the rotation axis 20. On the shaft 13, the Staubabscheide annoyed 9 can be moved in the longitudinal direction 14, that is, with respect to the plane of the drawing after the FIGS. 1 and 2 to the left and to the right.
  • the dust removal device 9 can be moved on the user side out of the "dust position" axially into the "cleaning position", that is to say in the longitudinal direction 14 with respect to the plane of the drawing FIGS. 1 and 2 to the left.
  • the actuator 23 has for this purpose a housing outside accessible slide 24, which cooperates with the interposition of a linkage 25 with the Staubabscheide issued 9.
  • the Staubabscheide noticed 9 is equipped with a turbine blading 21, which is arranged on the bottom plate 10.
  • the turbine blading 21 dips into a receiving space 22 provided by the dividing wall 3.
  • the turbine blading 21 is exposed, as the FIGS. 1 and 2 each can be seen in the below the respective axis of rotation 20 sectional view.
  • an additional space 26 is provided which is formed between the dust collecting space 4 and the receiving space 22.
  • the additional space 26 is separated from the dust collection chamber 4 by a partition, which has a passage opening 27 provides. Within this passage opening 27, the Staubabscheide issued 9 is held with its bottom plate 10 longitudinally displaceable.
  • the wall of the housing 2 is formed with air openings 28, through which a fresh air stream 29 can be sucked.
  • the rotationally symmetrical turbine blading 21 is located in this position of the Staubabscheidevorplatz 9 in the associated receiving space 22 and is not flowed through by the suction air flow 17. If the Staubabscheidevorplatz 9 user side brought by means of the actuator 23 in its "cleaning position", the turbine blading 21 is led out of the receiving space 22, whereby the turbine blading 21 is exposed to the suction air flow 17. Due to the increased flow resistance of the contaminated in the cleaning case Staubabscheidevorides 9 a large part of the Saugluftströmung 17 is no longer passed through the filter fabric 12 but through the turbine blading 21, as a result the dust collecting device 9 is set in rotation about the axis of rotation 20 defined by the shaft 13.
  • the speed of the Staubabscheidevoroplasty is, for example, between 1,000 and 5,000 revolutions per minute, as a result of which the filter fabric 12 adhering dust particles, impurities and / or the like contaminants are centrifuged off.
  • the actuator 23 can be released on the user side, which then induced by the compression spring 15 leads to a sliding movement of the Staubabscheidevorides 9 back into the "suction position".
