A device for separating and collecting waste entrained by an air flow generated by a suction group in a vacuum cleaner, the device having an air inlet tube opening in a tangential direction into a waste separation chamber, a conduit having a plurality of openings being located in a central part of said chamber, the conduit being in communication with the suction group, and the chamber being connected to a tank for collecting waste. According to the invention, the conduit has inclined walls directed toward the separation chamber, in the direction of circular movement of the air flow in the separation chamber, and the end of each wall has a substantially flat opening that is parallel to the underlying and adjacent conduit. The openings in the conduit are situated in line with the openings in the walls.

Device for separation of waste in a vacuum cleaner

The invention concerns a device for separating and collecting waste driven by an air stream, comprising an intake duct () emerging along a tangential direction in a waste separating chamber () defining an internal volume having substantially the shape of a cylinder, in the central part of said chamber () is arranged at least an opening () emerging onto a duct connected to a suction unit, said chamber () having a channel () for evacuating waste along a radial direction, said channel () being connected to a sealed pan () collecting centrifuged waste, the air intake channel () and the waste evacuating channel () being arranged substantially at the same height in the waste separating chamber (). The invention is characterized in that the diametrical section of the chamber () ranges between twice and ten times the smallest cross-section of the channel carrying waste from the nozzle.
