Definitions

  • the present invention relates to vacuum cleaners which incorporate a cyclone separator connected to a vacuum source and comprising a mainly cylindrical cyclone housing with an inlet through which dust laden air is tangentially drawn into the cyclone housing and a liner arranged below the cyclone housing and shaped as a hollow up-side-down truncated cone with a lower opening facing toward a collecting container, and wherein the cyclone separator encloses a disposable filter disposed between the inlet and the outlet of the cyclone separator.
  • Vacuum cleaners of the above mentioned type are previously known, see EP 33250.
  • This type of vacuum cleaner is designed such that particles separated by the cyclone fall down through the narrow opening of the truncated cone and are collected on the bottom of a container arranged below the cyclone.
  • the cyclone separator To empty the container, the cyclone separator has to be removed and the container has to be turned up-side down.
  • particles and liquid have a tendency to stick to the walls which means that the container also has to be cleaned manually which is unpleasant and troublesome work.
  • the filter has to be removed separately which means further unpleasant work.
  • a device for a vacuum cleaner includes a cyclone separator having a cyclone housing, a liner, a collecting container, an inlet, an outlet, and a disposable filter.
  • the inlet issues generally tangentially into the cyclone housing relatively above the liner.
  • the liner is shaped as an upside-down truncated cone, and has a lower opening facing toward the collecting container.
  • the outlet is centrally located in the upper end of the cyclone housing.
  • the container is adapted to receive an air-impermeable bag.
  • Means are provided for securing the bag by evacuating air from a space between the bag and the container walls.
  • the lower opening of the liner is sized to permit the filter to fall downwardly through the liner opening and into the bag or container.
  • FIG. 1 is a schematic vertical view showing a vacuum cleaner having a cyclone separator according to the present invention
  • FIG. 2 is a schematic vertical section of the cyclone separator according to the present invention.
  • a vacuum cleaner having a vacuum cleaner housing 10 enclosing a motor-fan unit 11 which serves as a vacuum source is illustrated.
  • An inlet side of the fan is connected to a cyclone separator 12 arranged at a relatively forward portion of the vacuum cleaner.
  • the cyclone separator 12, via a hose 13, a tube handle 14 and a tube shaft 15 communicates with a nozzle 16.
  • the cyclone separator 12 serves as a filtering assembly which is operable to remove dirt, dust, and other particles from a dirty air stream supplied via the hose 13 and exhaust cleaned air via the fan. As shown in FIG.
  • the cyclone separator 12 has an inlet part 17 shaped as a sleeve to which the hose 13 can be connected, an outlet part 18 which is connected to the inlet side of the fan unit 11, and a cyclone part disposed between the inlet part 17 and the outlet part 18.
  • the cyclone part includes a cylindrical cyclone housing 19 in which the inlet part 17 ends such that the incoming air is directed generally tangentially.
  • An upper end of the cyclone housing 19 is covered by a cover 20 having a centrally-arranged, downwardly-extending sleeve 21 which communicates with the outlet part 18.
  • the cover 20 is removably arranged on the cyclone housing and is retained thereon by means of clamps 22.
  • a cup-shaped filter holder 23 is disposed within the cyclone housing 19.
  • the filter holder 23 serves as a support for a disposable filter 24 which is arranged relatively beneath the holder. The filter holder 23 prevents the filter 24 from being drawn into the sleeve 21 and outlet part 18.
  • the filter 24 is preferably made of a comparatively thin, air-permeable paper.
  • the filter 24 is cup-shaped, and an outer periphery of the filter 24 is clamped between corresponding parts of the filter holder 23 and a portion of the cyclone housing 19 preferably without being folded downwardly.
  • the engagement between the outer periphery of the filter 24 and the upper edge of the filter housing 19 is preferably not sufficient to support the filter 24 when the cover 20 and filter holder 23 are removed from the cyclone housing 19.
  • the filter holder 23 can include a plurality of downwardly extending ribs in engagement with the filter 24 and between which the filter will crumple during operation.
  • a lower end of the cyclone housing 19 has a collar-shaped part 25 and receives a liner 26.
  • the liner 26 is shaped as a hollow, up-side-down truncated cone, and has a lower opening 27 facing toward a collecting container 28 for particles separated by the cyclone.
  • the opening 27 is sized such that the filter 24 can easily pass through the opening 27.
  • the area of the opening is greater than 10%, and preferably greater than 30%, of the cross-sectioned area of the container.
  • the collar-shaped part 25 of the cyclone housing 19 rests on the upper edge of the collecting container 28 and is retained thereon by means of several clamps 29, as illustrated.
  • the container 28 receives a circular plate 30 which, by means of widely spaced-apart distance means 31, is disposed above a bottom wall 32 of the container, thereby establishing a chamber 33 between the plate 30 and the container bottom wall 32.
  • the plate 30, which may be perforated, has a somewhat smaller diameter than the inner diameter of the container 28, so as to create a peripheral slot or gap 34 between the container side wall and the plate 30.
  • the chamber 33 is, by means of a nipple 35 and a tube conduit 36, connected to the outlet part 18 via a valve (not shown) .
  • the container 28 also receives a bag 37 which is preferably made from an air impermeable material, such as plastic.
  • An upper, open end of the bag 37 is clamped between the collar shaped part 25 and an upper edge of the container 28, as illustrated, and effectively seals the upper extent of the gap or slot 34.
  • the device operates in the following manner.
  • dust-laden air is drawn through the inlet part 17 and tangentially into the cyclone housing 19 to create a vortex around the filter 24.
  • Centrifugal forces cause heavier particles to be thrown outwardly toward the periphery of the cyclone housing, and gravitational forces cause the particles to fall downwardly toward a bottom of the bag 37.
  • the partially- cleaned air at the center portion of the cyclone housing then passes through the filter 24 to the outlet part 18, thereby further cleaning the air before it passes through the fan to ambient.
  • the cover 20 and the filter holder 23 are removed to release the upper edge of the filter 24 and thereby permit the filter 24 to fall downwardly through the opening 27 in the liner 26 and into the bag 37.
  • the bag 37 can be lifted out of the container 28 and thrown away with its contents.
  • the valve (not shown) is then in its open position.
  • the filter holder 23 can be integral with, or secured to, the cover 20.
  • the outer periphery of the cover is preferably shaped as a cone while the outer portion of the filter in a corresponding way extends obliquely upwardly and outwardly away from the container.

Abstract

L'invention concerne un dispositif destiné à un aspirateur doté d'un séparateur cyclone raccordé à une source de vide. Le dispositif comprend un boîtier cyclone (19) cylindrique doté d'une entrée (17) par laquelle l'air chargé de poussière entre tangentiellement. Une pièce rapportée (26), placé sous le boîtier cyclone, a généralement la forme d'un cône tronqué, creux et posé à l'envers. Cette pièce rapportée a une ouverture inférieure (27) faisant face à un récipient collecteur (28). Ledit récipient collecteur est placé sous l'ouverture. Une sortie (21) est située au centre du boîtier cyclone. Le séparateur cyclone abrite un filtre (24) jetable placé entre l'entrée (17) et la sortie (21).
