Definitions

  • the invention relates to a vacuum cleaner according to the preamble of the first claim.
  • a known vacuum cleaner of this type (DE-OS 17 03 053) is located in a front wall vertical in the operating position of the device housing, a connecting sleeve, the axis of which extends horizontally.
  • a connecting sleeve In an end wall of the sleeve pointing into the interior of the device housing there are two contact pins which run parallel to the axis of the connecting sleeve and are each pressed towards the open end of the sleeve by a contact spring.
  • These contact springs are connected to electrical lines, which lead to electrical devices arranged inside the housing.
  • the contact pins form counter-contacts to slip ring surfaces, which are provided on the front step heels of a connecting piece for a suction hose.
  • the slip ring surfaces which are electrically separated from one another and encircling the end face, are connected to electrical conductors which are guided in the hose jacket.
  • the slip ring surfaces are each connected to a cylindrical sleeve, one of which is fixed on the inner surface and the other on the outer surface of the connecting piece.
  • the invention has for its object to take a vacuum cleaner according to the preamble of the first claim measures by which a simple, axially short structure in the field of electrical contacting means is achieved.
  • the slip ring surfaces and mating contacts required for the electrical coupling can be arranged in the region of the outer surface of the connecting piece and the connecting sleeve, which is necessary for a secure fit of the connecting piece in the connecting sleeve anyway.
  • the slip ring surfaces only contribute to increasing the diameter of the connecting piece with their material thickness, and the mating contacts can be designed as tangentially guided sliding contact springs, which also have an insignificant space requirement in the radial direction.
  • the axis of the connecting sleeve or of the inserted connecting piece in the operating position and in the main direction of movement of the device housing is directed upwards at an acute angle and is perpendicular to a correspondingly inclined front side of the device housing.
  • This arrangement of the electromechanical rotary coupling on the device housing does not restrict the working area for the suction hose around the device housing, since when the suction hose is guided to the side, a force component occurs which causes the rotating coupling to rotate.
  • a second rotary coupling at the other end of the suction hose can be omitted without twisting with loops To have to accept suction hose when using.
  • a device housing (1) of a vacuum cleaner has a dust chamber cover (2) which is attached to it in a detachable or pivotable manner and is located in the operating position at the top.
  • the dust chamber cover (2) closes a dust collecting chamber in which a dust filter is arranged.
  • the dust chamber cover (2) has a front wall (3) which points in the main direction of movement indicated by the arrow (4) and is inclined at an angle of approximately 45 ° to the rear in the operating position shown.
  • the counter contacts are preferably on their lateral surface (6) adjacent side in the cross-sectional area shown in Figure 2 so curved that only their central parts can protrude beyond the lateral surface (6) and their edge zones remain hidden in the wall thickness of the connecting sleeve (5).
  • a connecting piece (8) is inserted axially into the connecting sleeve (5), the outer lateral surface of which in the area of the connecting sleeve has a diameter adapted to the inside diameter of the connecting sleeve (5).
  • closing ring surfaces (9) are embedded so that their circumference lies with the lateral surface of the connecting piece in a cylinder plane.
  • the locking ring surfaces (9) are formed by pipe sections made of electrically conductive material and are in electrically conductive contact with the counter contacts (7) in the working position shown.
  • a suction hose (10) is connected to the connecting piece (8), in which, for example, electrical conductors (11) worked spirally into the lateral surface are electrically connected to the slip ring contacts (9).
