Abstract: The present invention provides, in one embodiment, a vacuum cleaner nozzle comprising a nozzle body (1); a suction plate (2) having an elongated suction inlet (3), wherein the suction plate (2) is pivotally connected to the nozzle body (1) about a first pivot axis (A), which first pivot axis (A) extends parallel to the elongated direction of the suction inlet (3); a nozzle outlet device (5) having, at a first end thereof, a tubular opening (6), which tubular opening is matable with a tubular component (7) of a vacuum cleaner; and flexible hose (8) which is arranged to interconnect the suction plate (2) with the nozzle outlet device (5) such that the suction inlet (3) is in fluid communication with the tubular opening (6) of the nozzle outlet device (5).

Abstract: A cyclone separator for a vacuum cleaner. The separator has a cyclone chamber, an air entrance device having a flow passage arrangement therethrough for introducing an air stream into the cyclone chamber in a manner that causes the air stream to swirl in the cyclone chamber to remove dust from the air stream, and an air outlet for emitting the air stream from the cyclone chamber. The entrance device has a control member that is operable to alter the flow passage arrangement such that one or more properties of the air stream in the cyclone chamber are affected by the alteration. The flow passage arrangement has a first path and a second path, and the control member is operable to alter the flow passage arrangement by redirecting the air stream from the first path to the second path.

Abstract: An accessory unit of a vacuum cleaner, alone, with a vacuum cleaner conduit, and with a vacuum cleaner. The accessory unit has a housing, a first tool end, and a second tool end for releasable connection to a vacuum cleaner conduit. The first tool end has a first nozzle for vacuum cleaning, and the second tool end has two pivotable arms for forming second and third nozzles. Each arm has distal and proximal ends. The distal ends are arranged to be brought together for forming the second nozzle, and to be spread apart for forming the third nozzle. Furthermore, the arms are folded together to bring the distal arm ends in vicinity of each other for releasable connection of the second tool end to the vacuum cleaner conduit by at least partial insertion into said vacuum cleaner conduit.

Abstract: A vacuum cleaner comprising a vacuum cleaner housing (10) with a vacuum source and an inlet (13) for dust-laden air communicating with the vacuum source. The vaccum cleaner has a separation system for particles separated from the airflow that is placed after the inlet as seen in the airflow direction. The separated particles are collected in a bag (21) of a mainly airtight material. The vaccum cleaner is provided with a closing and/or sealing arrangement by which a bag (21) inserted into the vaccum cleaner is closed and/or sealed before the bag is removed from the vacuum cleaner.

Abstract: A device for a vacuum cleaner that has a vacuum source (12) connected to an inlet channel, and an outlet channel for air flowing through the vacuum cleaner. The vacuum cleaner includes a device for electrostatically charging a feather-duster (20) or a micro fiber type with static electricity.

Abstract: A device for a vacuum cleaner having a vacuum source communicating with an inlet channel and an outlet channel for air flowing through the vacuum cleaner. The vacuum cleaner includes a holder (19) for a dust pick-up tool such as a feather-duster (20) or a micro fiber-type duster/. The holder is provided with a chamber (21) which, by operation of a valve (28,30), can be connected to the inlet or outlet channel so that the dust pick-up tool is cleaned by the air flowing through the chamber.

Abstract: A vacuum cleaner having a housing (10) in which is disposed an electric circuit, a motor-fan unit (14), and a dust container (12). The dust container is received in a chamber (11). The chamber is provided with an opening (16) through which the dust container can be removed from the chamber. The opening is normally closed by a cover (17). The cover (17) is provided with a heat-transmitting surface which is thermally connected to at least one heat-generating power component (42) disposed in the cover.

Abstract: Method of passing an uninsulated, relatively rigid, conductor through an opening in a non-conductive housing wall. The conductor has a cross-section which is substantially less than the cross-section of the opening yet is firmly maintained in place by means of a rivet which presses a portion of the conductor against a surface surrounding the opening.
