  • the blower motor 4 can be switched on and off via a gun switch 6. With a boost or turbo button 7, the fan motor 4 can be operated temporarily at a particularly high speed.
  • Below the motor / fan unit there is a blow-out opening 8 for the suction air emerging from the motor / fan unit 5.
  • the vacuum cleaner 1 has a generally upright centrifugal separator 9.
  • This centrifugal separator 9 is arranged essentially parallel to the fan motor 4 of the motor-fan unit 5, which is also arranged upright.
  • a suction nozzle 10 is provided on the centrifugal separator 9, specifically in its upper area, a suction nozzle 10 is provided with which suction air can be drawn into the centrifugal separator 9.
  • the suction connector 10 is essentially tubular, the longitudinal axis of this tube running perpendicular to the longitudinal axis of the centrifugal separator 9.
  • various attachment elements not shown, e.g. B. different suction nozzles, or a suction tube can be attached.
  • the centrifugal separator 9 is shown in more detail. It is pot-shaped with a cylindrical jacket 11 and a closed base 12 that is integral with the jacket 11. The top of the centrifugal separator 9 is open but covered by the cover component of the vacuum cleaner 1. The bottom 12 of the centrifugal separator 9 cannot be opened due to the closed bottom 12, which is integral with the jacket 11 of the centrifugal separator 9, which in particular also prevents a dust collector 13 of the centrifugal separator 9 from being emptied through the bottom.
  • the centrifugal separator 9 comprises a separating device 14, which is arranged in the upper part of the centrifugal separator 9, and the dust collecting container 13 in the lower part.
  • the separating device 14 comprises a filter 15 which is surrounded by this jacket surface and which can be removed from the centrifugal separator 9 in order to empty the dust collector 9.
  • the air which has already been partially freed of dust in this way, now passes through the filter 15 of the separator 14, as a result of which further dust and other components can be removed from the air. As a rule, these constituents also fall from the filter into the dust collection container 13 following the force of gravity.
  • the air passes through the filter 15 via a deflection pipe 17, which is present in the cover component of the vacuum cleaner 1, into the motor / fan unit 5 of the vacuum cleaner 1 and is blown out through the exhaust opening 8 of the vacuum cleaner 1.
  • the suction port 10 is also equipped with a protective flap 18, which prevents the downwardly tilted nozzle 10 and switched off blower motor 4 dust from the dust collecting device 13 passes through the suction nozzle 10 back to the outside.
  • the vacuum cleaner 1 When the vacuum cleaner 1 is placed on a flat, horizontal surface, the vacuum cleaner 1 rests partly on the floor 12 of the centrifugal separator and partly on a foot 19 which is arranged below the blow-out openings 8 of the motor-fan unit 5. On the other hand, the vacuum cleaner 1 in particular does not rest on the battery pack 3 arranged below the handle 2. In this way, it is possible for a user to easily reach the battery 3 for the purpose of replacement.
  • the vacuum cleaner 1 also has an actuating element 20 with which the centrifugal separator 9 can be detached from the rest of the vacuum cleaner 1 in order to remove it from the rest of the vacuum cleaner 1.
  • an actuating element 20 To the actuating element 20 is an in Figures 3 and 4th recognizable bolt 21, which is in a blocking position when the centrifugal separator 9 is inserted in the vacuum cleaner 1 and the actuating element 20 is not actuated at the same time, in which it interacts in a locking manner with a stop on the cover component 13 of the vacuum cleaner 1 in such a way that the centrifugal separator 9 cannot be removed from the vacuum cleaner 1.
  • the bolt 21 In the actuated state of the actuating element 20, however, the bolt 21 is in an open position in which it no longer interacts with the stop in a blocking manner, so that the centrifugal separator can be removed from the vacuum cleaner 1.
  • the actuating element 21 is designed as a pushbutton switch which is pretensioned in the blocking position with a spring element in the form of a helical spring. If the actuating element 20 is moved downwards against the force of the spring element, the bolt 21 also moves with it under the stop, whereby the centrifugal separator 9 is released so that it can be released from the vacuum cleaner 1.
  • the bolt 21 is equipped with a bevel, whereby the bolt 21 (and with it the actuating element 20) when the centrifugal separator 9 is reinserted is moved by the bevel against the force of the spring element in the actuating direction of the actuating element 20, so that the bolt 21 is moved under a The lower edge of the stop can go through back into its blocking position here the stop. With the same effect, the run-up bevel can be arranged instead of on the bolt 21 or in addition to it on the lower edge of the stop.
  • the actuating element 20 is arranged on the upper side of the suction nozzle 10 so that it can be reached with the thumb or another finger of the hand surrounding the suction nozzle 10.
  • the button of the actuating element 21 clearly protrudes in the non-actuated position out of the plane of the suction connector 10 upwards. In this way, it can be avoided that it is inadvertently already actuated when gripping the suction connector 10.
  • a base 22 of the actuating element (in Figures 4 , 5 and 6th easily recognizable), which also protrudes from the plane of the suction nozzle surface.
  • the centrifugal separator 9 To remove the centrifugal separator 9, it can be tilted around the axis of a joint with a hand grasping the suction nozzle 10. The tilting takes place against the intended direction of flow of the suction air.
  • the joint and thus also the pivot point are located on the side of the centrifugal separator opposite the suction nozzle 10 in the lower region of the centrifugal separator 9 and the vacuum cleaner 1.
  • the joint consists of a first coupling element, which is arranged on the centrifugal separator 9, and a second coupling element that can be connected to it, which is adjacent to the centrifugal separator 9 at the level of the exhaust opening 8 of the vacuum cleaner 1.
  • the first element is designed as a pin 23, the second as a shell 24 in the form of a cylindrical groove in which the pin 23 comes to rest when the two coupling elements are connected.
  • the pin 23 When tilted, the pin 23 is rotated about its longitudinal axis relative to the shell 24.
  • the pin 23 can be lifted out of the shell 24 by lifting the pin 23 relative to the shell 24 in order to remove the centrifugal separator 9 from the vacuum cleaner 1.
  • this is not possible because the cover component of the vacuum cleaner 1 prevents the pin 23 from being lifted relative to the shell 24.
  • the filter 15 is first removed, as in FIG Figure 5 shown. Then the centrifugal separator 9 can be rotated around the longitudinal axis of the suction nozzle 10 with the hand that grips it at the suction nozzle 10 so that the dust can be emptied through the opening of the centrifugal separator 9. In this way is the Dust collection container 13 can be emptied easily. In particular, the dust can carefully get into the in Figure 6 trash can 25 also shown are emptied. The emptying can be metered by determining the angle by which the centrifugal separator 9 is rotated about the longitudinal axis of the suction nozzle 10 in order to avoid the formation of a dust cloud. Then the centrifugal separator 9 can still be cleaned, for. B. with a damp cloth. The filter 15 can be exchanged if necessary.
  • the (possibly new) filter 15 can then be reinserted into the centrifugal separator 9, and the centrifugal separator 9 can be attached to the other part of the vacuum cleaner 1 in a tilted position so that the pin 23 engages in the shell 24.
  • the centrifugal separator 9 can now be moved back into its non-tilted position until the bolt 21 has passed the lower edge of the stop again into its blocking position, so that the vacuum cleaner 1 is ready for operation again.
  • the vacuum cleaner according to the invention collects dust, dirt and liquids reliably and is easy to empty.
