Abstract:
A multi-cyclone dust-collecting apparatus is provided in which maintenance and repair are made easier while a compact size is maintained. The multi-cyclone dust-collecting apparatus includes a first cyclone dust-collecting unit to separate dust from drawn-in air, and a plurality of second cyclone dust-collecting units to separate dust from air discharged from the first cyclone dust-collecting unit, the plurality of second cyclone dust-collecting units enclosing the first cyclone dust-collecting unit, wherein part of the first cyclone dust-collecting unit and part of the second cyclone dust-collecting units form the external surface of the multi-cyclone dust-collecting apparatus.
Abstract:
The invention provides a handheld cleaning appliance (10) comprising a main body (12), a dirty air inlet (18), a clean air outlet (24) and a cyclonic separator (100) for separating dirt and dust from an airflow located in an airflow path leading from the air inlet (18) to the air outlet (24). The cyclonic separator (100) is arranged in a generally upright orientation. A base surface (172) of the main body (12) and a base surface (174) of the cyclonic separator (100) together form a base surface of the appliance (10) for supporting the appliance (10) on a surface. By providing a base surface of the appliance (10), which is made up of the base surface (172) of the main body (12) and the base surface (174) of the cyclonic separator (100), the appliance (10) is provided with a substantial base surface on which the appliance (10) can be stably and reliably supported. This is also achieved without substantially increasing the size of the appliance (10) as a whole.

Der Fliehkraftabscheider (5) und der Staubsammelbehälter (6) sind in einem Gehäuse des Staubsaugers zwischen Staubsaugerdeckel (2) und Staubsaugerunterteil (1) angeordnet. Erfindungsgemäß ist der Fliehkraftabscheider (5) an dem Staubsaugerdeckel (2) befestigt.
Abstract:
A vacuum cleaner includes a housing (12) as well as a suction generator (38) and bagless dirt system carried on the housing. The bagless dirt system includes a dirt cup (60), a prefilter (46), a filter chamber (32) remote from the dirt cup, a filter (36) in the filter chamber and a first conduit (50) providing fluid communication between the dirt cup and the filter chamber. A second conduit (54) provides fluid communication between the filter chamber and the suction generator.
Abstract:
A bagless canister vacuum cleaner (A) includes a selectively removable dirt cup (D), and an airstream (S) flows rotationally through the dirt cup (D) between an interior wall (31) of the dirt cup (D) and a filter assembly (F) selectively mounted in the dirt cup (D) so that entrained contaminants are separated from the airstream (S) flowing through the dirt cup (D) and collected by the dirt cup (D). The filter lies substantially parallel to the support surface on which the vacuum cleaner (A) is supported. A cover member (74) is connected to the main housing (B), and the cover member (74) is selectively movable to and held in an operative position in covering relation with an open first end (32) of a dirt cup (D). The main housing (B) defines a base (150) conformed to self-support the main housing (B) on a support surface with the dirt cup (D) arranged with its open first end (32) at a higher elevation than is closed second end (34). The removable dirt cup (D) includes a handle (80) adapted for being held by a user, and the dirt cup (D) defines or includes a spout (58) to facilitate emptying dirt therefrom.
Abstract:
An upright vacuum cleaner (A) includes an upright housing section (B) and a nozzle section (C). A cyclonic airflow dirt and dust separating chamber (54) is defined in said upright housing section. A suction source (E) pulls air and entrained dirt, dust, and other contaminants through a main suction opening (26) formed in the underside (24) of the nozzle and into the cyclonic airflow chamber (54). The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container (52) that defines the chamber (54). A main filter element (K) filters residual contaminants from the suction airstream between the chamber and the suction source. The main filter element is preferably made from high-density polyethylene porous filter media. A final filter assembly (F) filters the suction airstream discharged by the suction source to ensure that the air discharged into the atmosphere is contaminant free, including those contaminants introduced into the airstream by the suction source itself.
Abstract:
An apparatus and method for filtering a dirty air stream in a vacuum cleaner to obtain a clean air stream comprises subjecting the dirty air stream to a first cyclonic separation stage (32) to obtain a partially cleaned air sream and subjecting the partially cleaned air stream to an electronic filtration stage (50) and optionally a second cyclonic separation stage (60) to obtain the clean air stream. The electronic filtration stage (50) is optionally removable with a cyclonic cleaning stage from the vacuum cleaner. The electronic filtration stage (50) is optionally an electrostatic precipitator which utilizes air flow through the vacuum cleaner to generate the voltage used by the electrostatic precipitator.
