摘要:
A method for treating dust including: separating, in a vacuum cleaner, the dust into at least two fractions which differ in at least one of a size and a mass of particles of the dust; and adding a dust-binding agent to at least a first of the fraction.
摘要:
A method for operating a vacuum cleaner having a fan, an electronic control system for the fan and/or another load, and a dust chamber for receiving an air-permeable dust bag, includes providing the dust bag with an identifier, and providing the vacuum cleaner with an identifying device associated with the electronic control system and configured to identify the identifier. When the identifier fails to be identified, at least one of the fan and the other load is controlled using the electronic control system so as to reduce at least one parameter associated with an intake of dust into the dust bag.

摘要:
A device for separating dust from dust-laden air. The device includes a first cyclone separator having an inlet portion with a tangential inlet. An axial inlet cyclone separator is disposed downstream of the first cyclone separator. The axial inlet cyclone separator has an air inlet disposed within the first cyclone separator. The axial air inlet includes a widening tubular section in the shape of a funnel extending into the inlet portion of the first cyclone separator.

摘要:
A circuit arrangement for preventing the discharge of a battery powering a signal evaluation circuit while the circuit is in a stand-by mode, provided with a sensor for generating signals and means responsive to the generation of signals for connecting the battery to the signal evaluation circuit and for disconnecting the battery in the absence of signals. The signal responsive means include an amplifier for triggering a monostable flip flop the output of which controls the conductivity of a transistor between the battery and the signal evaluation circuit.
摘要:
A filter includes a filter medium, a filter inlet side, a filter outlet side and an indicator device. The indicator device is configured to be acted upon by air flow through the filter and is disposed adjacent to the filter medium and extends from the filter inlet side to the filter outlet side. The indicator device includes an air path starting from the filter inlet side, a viewing window covering the air path on the filter outlet side, and a flow-through usage indicator configured to receive filtered material and disposed in the air path and visible beneath the viewing window on the filter outlet side.
