Definitions

  • the invention relates to a vacuum cleaner with a speed-controllable blower motor according to the preamble of claim 1.
  • Such a vacuum cleaner is known from DE-OS 20 16 194.
  • an electronic control circuit is arranged in its engine compartment, which has a rotary knob that can be operated from the outside of the vacuum cleaner housing in order to set a certain speed.
  • an on-off switch which can also be actuated from the outside is provided.
  • the semiconductor switching element required for speed control is arranged towards the dust chamber for cooling reasons. All of these elements are connected via separate lines, the laying of which means considerable installation effort.
  • the invention has for its object to design a vacuum cleaner of the generic type so that the effort for the assembly of the connecting lines is largely eliminated.
  • connection of all elements via a common printed circuit board eliminates all connecting cables that have to be routed and connected separately.
  • the printed circuit board is expediently connected to the cable located on the cable drum via a plug contact connection.
  • a vacuum cleaner designed in accordance with the features of subclaim 3 is characterized by great robustness and particularly simple attachment of the printed circuit board in the vacuum cleaner housing.
  • the mounting of the supporting part receiving the printed circuit board by means of a clamp connection does not require any special holding elements and is therefore particularly easy to manufacture.
  • the attachment of the switching element to the support member has the advantage that the actuating forces for this switching element are kept away from the circuit board. Likewise, undesirable effects of force on the printed circuit board are also kept away from the latter by the fact that the adjusting element for the control element is movably attached to the vacuum cleaner housing. Forces that are not used to adjust the control element are absorbed by the housing.
  • a hub recess 6 is formed on the fixed housing part 5 of the cable drum 4. At the bottom of this hub recess 6 there are two plug contacts 7, which are connected to the wires of the cable 8 wound on the cable drum 4.
  • a circuit board 10 is attached.
  • the electrical and electronic components required for the speed control of the blower motor 11 are arranged on the printed circuit board and are electrically connected to one another via the conductor tracks of the printed circuit board.
  • a potentiometer necessary for the speed adjustment is designed as a slide potentiometer, the conductor tracks 12 are also provided on the circuit board 10 and the slide 13 is arranged on the side edge 25 of the circuit board 10 adjacent to the top of the vacuum cleaner housing and the side edge with a U-shaped contact part 13a 25 overlaps.
  • the slide 13 is actuated via a displaceable adjusting element 14 arranged on the outside of the housing.
  • a switch 15 used to switch the blower unit on and off is fastened to the supporting part 9 and connected to the corresponding conductor tracks of the printed circuit board 10 by means of plug-in tabs 16.
  • the switch 15 is actuated via a step button 17, which acts on the switching plunger 19 of the switch 15 via a plunger attachment 18. Since the switch 15 is fastened to the support part 9, the actuating forces are absorbed by the latter, so that the printed circuit board 10 is not burdened thereby.
  • the support part 9 itself is held by means of a projection 20 which is molded onto it and fits into the hub recess 6 of the fixed housing part 5 of the cable drum 4.
  • the extension 20 is dimensionally designed so that it sits firmly clamped in the hub recess.
  • the mating contacts 7 are arranged corresponding mating contacts 21, which in turn are connected to corresponding conductor tracks of the printed circuit board 10.
  • a spring 24 is provided on the slide 13 of the slide potentiometer, which has two spring arms 26 resting on both sides of the slide 13 on the side edge 25 of the printed circuit board 10.
  • the side edge 25 overlap tabs 27 are formed on both sides, so that the spring arms 26 are guided when adjusting the slide 13 and can not slip off the side edge 25.
  • the slider 13 is pressed by the spring arms 26 against an overlapping bar 28 formed on the support part 9. Characterized the slide 13 is secured in the correct position on the circuit board 10, so that its contact part 13a is always in engagement with the conductor track provided on the circuit board 10. Tilting of the slide 13 is also prevented by the spring arms 26 resting on the side edge 25 under tension.
  • the adjustment element 14 is coupled to the slide 13 via a spur 29 formed on the adjustment element 14, which engages in a corresponding slot 30 provided on the slide 13.
  • a spur 29 formed on the adjustment element 14, which engages in a corresponding slot 30 provided on the slide 13.
  • blower motor 11 is still connected to the printed circuit board 10 via lines 23.
  • Such a line connection can also be replaced by a direct plug contact connection of the blower motor 11 to the printed circuit board 10.
