Definitions

  • the invention relates to a hand-held cyclonic vacuum cleaner.
  • the hand-held cyclonic vacuum cleaner is also referred to below as a vacuum cleaner.
  • cyclone vacuum cleaner is to be understood as meaning a vacuum cleaner that is bagless and in which turbulence and any turbulence are generated in an air flow entering the vacuum cleaner, whereby suction material such as dust particles are pressed in a predetermined direction due to centrifugal force and in a Separator of the vacuum cleaner are deposited.
  • bagless means that the suction material in the vacuum cleaner is collected directly in the separator without a bag or similar exchangeable filter medium for receiving suction material being arranged in it, so that the user has to empty the suction material from the Suction material container no bag or the like. Removes from the suction material container. Rather, the suction material is collected directly in the separator and emptied from it.
  • a hand-held cyclone vacuum cleaner with a separator which has a housing, a central filter arranged in the housing and a fine filter which is arranged in the central filter and which is designed in such a way that it is in the housing when the central filter is removed from the housing remains.
  • the user has disadvantages in terms of handling and the performance of the vacuum cleaner.
  • the central filter cannot be accessed by the user when it is being cleaned and that he always has to disassemble the separating system in order to achieve a performance gain by cleaning the central filter.
  • the invention therefore addresses the problem of providing a hand-held cyclone vacuum cleaner in which handling for the user and the performance of the central filter are improved.
  • the advantages that can be achieved with the invention are that the user can use the cleaning function of the central filter during operation, since this can be done directly from the outside is accessible, and that the user does not have to carry out an additional handling step in order to remove the central filter from the separator.
  • the user thus has an increase in comfort.
  • the cleaning mechanism for the central filter that is integrated in the vacuum cleaner can be operated manually by the user during operation and when the vacuum is not being used.
  • the central filter in the vacuum cleaner according to the invention is designed in such a way that it has a rotatable handle, which is used for cleaning in the first state and also, through the rotary movement in the predetermined direction of rotation, in the second state is used to enable the user to remove the central filter from the separator .
  • the cleaning is designed in such a way that the user can clean the central filter during operation and in a vacuum break without detaching the separator from the device body. In this way, a good performance of the central filter can be achieved again very quickly.
  • the vacuum cleaner has an automatic or automated lock that prevents the central filter from being removed from the separator as long as the separator is connected to the body of the device.
  • the central filter is for the User from the separator in the second state easily and easily removed without the risk that dirt can fall into the drive unit when removing the central filter.
  • the central filter is designed in such a way that it can be cleaned individually after removal from the separator. Furthermore, thanks to the implemented filter system, the user has relatively few elements that need to be cleaned.
  • the separator is preferably constructed in such a way that the central filter is arranged concentrically inside the housing.
  • the intake area of the power unit is located downstream of the central filter, facing the air flow. If the central filter is removed, the separator has direct access to this suction area from above as long as it is connected to the body of the device.
  • the separator and the device body are fluidically connected to one another via the opening.
  • the separator In the first state, the separator is detachably connected to the device body, i.e. mounted on it.
  • the separator is detached from the device body, i.e. not connected to it or dismantled from it.
  • the fact that the user can only remove the central filter from the separator in the second state prevents the interior of the device body from becoming dirty, in particular the drive unit, when it is removed.
  • the handle preferably has one or more recessed grips.
  • the recessed grip(s) are preferably designed in such a way that the user can turn the handle using the recessed grip(s). As a result, the handle is easy for the user to manipulate and rotate.
  • the central filter in the separator is preferably non-rotatable, ie the central filter does not rotate with the handle when the handle is rotated.
  • the central filter is arranged concentrically in the housing and the separator has an axis which is arranged inside the central filter, which is connected to the rotatable handle and on which one or more cleaning elements are designed and arranged in such a way that that when rotating the rotatable handle in the first state, he or she cleans the central filter by contact and the resulting pulse transmission.
  • the central filter preferably has folds.
  • the axis is preferably designed in such a way that when it is rotated it moves on the inside of the central filter and engages with the cleaning element or elements in the folds of the central filter.
  • the cleaning element or elements Due to the rotary movement, the cleaning element or elements generate an impulse on the filter, which leads to cleaning.
  • the separator and the device body are connected to one another, it or they are preferably designed in such a way that the central filter is cleaned when the handle is turned, regardless of the direction of rotation, ie whether clockwise or counterclockwise.
  • the axis is preferably designed to be connected to the handle via a form-fitting connection to turn. That is, in the first state, the axle and the handle are preferably connected to one another in a form-fitting manner.
  • the device body preferably has a drive unit protective grille which is arranged and designed in such a way that in the first state it forces the axis into a first position in which a connection between the rotatable handle, a filter holder of the separator and the axis with a play, preferably one axial play is designed.
  • the play in the second state is preferably non-existent.
  • the first position is preferably an upper position. Position and direction information relate to a working position of the vacuum cleaner.
  • the separator has a spring adapted to be pushed by the axle in the first condition to the first position, the axle being seated against an end stop in the filter seat.
  • the spring is further configured to be compressed between the axle and the rotatable handle in the first state.
  • This spring is preferably designed as a compression spring.
  • the axle is preferably pushed far enough (upward) through the drive unit protective grille that it sits at the end stop in the filter holder.
  • the handle is preferably also moved into a first, preferably upper, handle position, with a latching point between the filter holder and the handle preferably representing a stop.
  • the handle therefore preferably has a latching point with the filter receptacle, which represents a stop when the handle is arranged in the first, preferably upper, handle position.
  • the play between the axis in the filter holder is preferably at least as large as the sum of the axial play between the handle and the filter holder and the axial play between the axis and the handle.
  • the play between the handle and the axle is preferably at least twice as large as the play between the handle and the filter holder. As a result, there is play in this first position between the end faces of the filter holder and the handle. This game ensures that a rotary movement of the handle is only transmitted to the axis.
  • the spring is preferably designed in such a way that in the second state it presses the axle into a second position in which one or more latching elements of the axle are in contact with the handle.
  • the spring is decompressed in the second state.
  • the second position is preferably a lower position. If the separator is or is detached from the device body, ie not mounted with it, the drive unit protective grille as a counter bearing for the axle is omitted.
  • the axle is pressed into its second, preferably lower, position by the spring located between the handle and the axle.
  • This is preferably characterized in that the one or more locking elements of the axis on the handle preferably rest at the bottom of the handle. Since the counter bearing for the handle is also missing due to the downward movement of the axis, the latter moves by gravity into a second, preferably lower, handle position. As a result, the play between the components in the longitudinal direction no longer exists or does not exist.
  • the rotatable handle and the filter holder each have one or more drivers which are designed to engage in one another in the second state.
  • the drivers are preferably each formed on an end face.
  • the rotatable handle has a further driver and the filter holder has teeth and a geometry of the rotatable handle is designed such that the further driver engages in the teeth in the second state.
  • the additional driver and the toothing are each preferably arranged centrally.
  • the toothing is preferably designed in such a way that it has a bevel which is designed in such a way that the further driver rises over the bevel when the rotatable handle is rotated counter to the predetermined direction of rotation and is released from the toothing, so that the central filter is in the second state can be cleaned when the rotatable handle is rotated counter to the predetermined direction of rotation.
  • the toothing is preferably designed in such a way that it has the bevel on one side.
  • the fact that the bevel is preferably designed such that when the handle is rotated counter to the predetermined direction of rotation, preferably anti-clockwise, the handle with its driver rises over it and disengages from the toothing, a kind of freewheel is created.
  • the central filter can continue to be cleaned when turning against the predetermined direction of rotation via the power transmission handle - axis.
  • the separator also has at least one ramp, which is designed in such a way that the central filter can be unscrewed from the housing when the rotatable handle is rotated in the predetermined direction of rotation in the second state. This also ensures that the central filter is released from the separator by rotating the handle in the predetermined direction of rotation, more preferably clockwise. If the handle is turned in the predetermined direction of rotation, it is transferred to the filter holder. This movement is then converted into a combination of linear and rotary movement via the at least one ramp, so that the central filter unscrewed from the housing. As a result, the central filter can be removed from the separator in the second state and cleaned individually.
  • the separator preferably also has a pre-filter which is arranged in the housing and in which the central filter is arranged.
  • the pre-filter is preferably arranged concentrically in the housing of the separator.
  • the pre-filter is preferably arranged concentrically surrounding the central filter.
  • the pre-filter serves in particular as filter protection for the central filter.
  • the pre-filter is located upstream of the central filter. Only suction material such as dust that has not settled on the pre-filter settles on the central filter.
  • a three-stage filter system is preferably provided, in which the cyclone generated by the drive unit serves as the first filter stage, the pre-filter serves as the second filter stage and the central filter serves as the third filter stage.
  • the central filter is preferably mounted non-rotatably or non-rotatably in the pre-filter.
  • the central filter is preferably mounted non-rotatably in the pre-filter due to the geometry of the filter mount.
  • the pre-filter preferably has the at least one ramp.
  • the vacuum cleaner is preferably a cordless vacuum cleaner. That is, the vacuum cleaner has an accumulator and is designed to be operated using the accumulator as a power source.
  • the accumulator can be connected to the separator and/or the device body, preferably the device body.
  • the central filter serves in particular to store dust and is preferably designed as a fine filter. It is preferably designed as a depth filter. For this purpose, it has one or more corresponding filter elements.
