Definitions

  • the invention relates to the technical field of vacuum cleaners and more particularly to separators according to the introductory part of claim 1.
  • Such a vacuum cleaner is shown in FR-A-670220.
  • Vacuum cleaners adapted for the suction of liquids require special provisions depending on whether solid particles (dust) and/or liquids (water) is/are to be sucked. Furthermore, with conventional vacuum cleaners, the suction of hot and incandescent particles (e.g. ash, welding cinder, close-burning coal etc.) is not possible.
  • the object of the invention therefore is to provide a separator for a vacuum cleaner which avoids the above mentioned disadvantages.
  • the aim of the invention is achieved by the measures proposed in the characterising part of claim 1.
  • the inventive separator is positioned vertically to the surface of the medium. Further embodiments and improvements of the invention are described in the subclaims.
  • the instant hydroactive separator of solid particles and liquids forms a diffusor at the ending of the suction tube, installed in the vacuum cleaner's container. All parts of the construction are solidly connected to each other.
  • the use of a flexible suction tube, eventually made of ribbed rubber (bellows) and/or the use of floats enabling the raise or fall of the separator - depending on the water level - is preferred.
  • CARRIER REINFORCEMENT 1 its function (purpose) is to reinforce the construction and to build a cylindrical diffusor.
  • LINKS 2 - present the hard connection between the protective cylinder 4 and the other parts of the separator.
  • DIFFUSOR 3 - forms the ending of the flexible suction tube 14.
  • PROTECTIVE CYLINDER 4 - a part of construction which has on its upper part a sectional conical surface, that directs the air current 9 to the protective cover 5.
  • PROTECTIVE COVER 5 prevents spraying of water onto the vacuum motor 12 inlet. Further sheet guides between said protective cover 5 and said vacuum motor 12 could be provided.
  • the cylindrical surface between the upper border of the protective cylinder 4 and the protective cover 5 is smaller than the cylindrical surface between the lower border of the protective cover brink and the surface of the liquid 7. Such a relation is necessary because of the decrease of the air current speed and enables separation of remaining water droplets from the air current (in consequence of gravity). On the borders of the protective cover 5, floats 6 are attached.
  • FLOATS 6 - enable the separator to maintain a constant position in relation to the water surface.
  • the water level, when the vacuum cleaner is off, has to cover the links 2.
  • the water presents the medium by means of which the solid particles, liquids and other materials can be separated from the air current 9.
  • the parts 1 to 5 may be held rigidly with respect to the housing 10.
  • Fig.3 presents a partial section of the separator and the function of the device when the vacuum cleaner is on.
  • the vacuum cleaner is turned on, and in consequence of the outside atmosphere effect in the suction tube 14, i.e. in the diffusor 3, the water level is lowered.
  • Particles of dust with bigger mass because of the centrifugal force, unable to be directed to the protective cylinder 4 and to the protective cover 5, rush into the water and sink down or are dispersed in the water.
  • Particles of dust with small mass to which centrifugal forces have no significant effect, are directed via the air current to the protective cover 5 and are trapped in sprayed water when coming in contact with it.
  • the conical part of the protective cylinder 4 enables extra whirling circulation where the rest of the light particles is trapped in water and thereby moved out of the air current.
  • liquids could be used, e.g. desinfectant liquids like cardi, or the like for avoiding a bacteriological pollution.
  • the liquid could be exchanged permanently via tubes (not shown).

Claims (10)

  1. Separator für feste und flüssige Partikel aus einem Luftstrom (9), der insbesondere für Staubsauger anwendbar ist, mit einem flüssigen Abscheide- bzw. Filtermedium (7), durch welches der Luftstrom (9) - im Abscheide- bzw. Filtrierzustand - hindurch- oder entlang des flüssigen Mediums (7) gesaugt wird, um die festen Partikel mit der Flüssigkeit in Kontakt zu bringen und sie aus dem Luftstrom zu entfernen, wobei der Separator
       ein Saugrohr (11, 14) mit einem Auslaß aufweist, durch den der Luftstrom (9) - im Abscheide- bzw. Filtrierzustand - zum Medium geführt wird,
       dadurch gekennzeichnet, daß das Saugrohr (14) zum Erlauben von vertikalen Bewegungen seines in Form eines Diffusors (3) ausgebildeten Auslasses biegsam ist, und daß der Diffusor (3) über Verbindungen (2) mit einer Schutzeinfassung (4) verbunden ist, wobei der Diffusor (3) und die Schutzeinfassung (4) zum Erlauben des Schwimmens des Diffusors (3) und der Schutzeinfassung (4) auf dem flüssigen Medium - im Abscheide- bzw. Filtrierzustand - mit Schwimmern (6) verbunden sind.
  2. Separator nach Anspruch 1, dadurch gekennzeichnet, daß er ferner oberhalb der Schutzeinfassung (4) eine Schutzabdeckung (5) aufweist, welche Abdeckung (5) mit dem Auslaß verbunden ist, wobei die Schutzeinfassung (4) und der Diffusor (3) mindestens zum Teil in das flüssige Medium (7) eintauchbar sind.
  3. Separator nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Schutzeinfassung (4) zum Leiten des Luftstromes (9) gegen die Schutzabdeckung (5) einen konischen oberen Teil aufweist.
  4. Separator nach einem der Ansprüche 2 bis 3, dadurch gekennzeichnet, daß die aus dem Diffusor (3), der Einfassung (4) und der Abdeckung (5) bestehenden, fest miteinander verbundenen Teile eine Anordnung zum Verringern der Geschwindigkeit des Luftstromes aufweisen, wobei die Einfassung (4) und die Schutzabdeckung (5) jeweils scheibenförmig bzw. zylindrisch sind.
  5. Separator nach Anspruch 4, dadurch gekennzeichnet, daß der abgedeckte Flächenbereich des Mediums (7) zwischen dem Auslaß des Saugrohres (14) und der Einfassung (4) kleiner ist als der abgedeckte Flächenbereich des Mediums (7) zwischen der auf dem Medium (7) schwimmenden Einfassung (4) und der Schutzabdeckung (5).
  6. Separator nach Anspruch 4, dadurch gekennzeichnet, daß die Zylinderfläche zwischen dem oberen Rand der Schutzeinfassung (4) und der Schutzabdeckung (5) kleiner als die Zylinderfläche zwischen dem unteren Rand der Schutzabdeckung (5) und der Oberfläche des Mediums (7) ist, oder daß die in das flüssige Medium (7) eintauchende Zylinderfläche der Schutzeinfassung (4) größer als diejenige Zylinderfläche der Einfassung (4) ist, welche oberhalb des flüssigen Mediums (7) verbleibt.
  7. Separator nach einem der vorhergehenden Ansprüche, bei dem die Schwimmer (6) das Gewicht des Auslasses tragen und alle Teile mit ihm verbunden und so ausgebildet sind, daß sie es den Verbindungen (2) gestatten, mit der Oberfläche des Mediums (7) immer dann in Kontakt zu kommen, wenn sich der Separator im Ruhezustand befindet.
  8. Separator nach einem der vorhergehenden Ansprüche, bei dem das Medium ein Desinfektionsmittel ist oder ein solches enthält.
  9. Separator nach einem der vorhergehenden Ansprüche, bei dem die Verbindungen (2) zum zyklonartigen Drehen des Luftstromes (9) eine propellerblattförmige Gestalt haben.
