Definitions

  • the present invention relates to an automatic device for lifting waste water for discharging into sewers.
  • devices which consist of a receptacle forming a relay into which the water ends, and when the level reaches the sufficient height, a float switch controls the setting in running, and conversely stopping, a submersible pump.
  • the device according to the invention makes it possible to obtain permanent regular suction. It is miniaturized in order to be able to be housed at a very low height and in any case not higher than the usual height of the bottom of the receptacle located lowest, that is to say a shower tray, to obtain the required lower part.
  • FIG. 1 represents the lifting device according to the invention in isolation
  • FIG. 2 a view of the same device applied to a receptacle of shower.
  • the body 1 of the elevator includes the conduit 2 for supplying the water to be evacuated connected to the receptacle R to be drained (a shower tray in this example).
  • This conduit which penetrates at the base of the body 1, is directed upwards to a vertex 3 in the form of a pronounced elbow.
  • the section of this part 2 of the conduit is strongly decreasing to the vertex 3 from which the part 4 of the duct is sloped with a larger section to lead to the body of a conventional suction pump 5 included in the body 1.
  • a miniature float 6 mounted on a very short lever arm 7.
  • the reference P designates an air intake.
  • the operation of the device is as follows: the water fluid arrives from bottom to top according to the arrow and acts on the float 6 which then controls an electrical contact determining the activation of the suction pump 5.
  • the significant narrowing of the duct 2 upstream of the apex 3 forms a constriction which produces a Venturi effect which, combined with the suction of the pump 5, causes an absolutely complete rapid evacuation by the duct 8, even for a very low flow rate.
  • the float 6 returns to its rest position, thus controlling the stopping of the pump 5 by cutting the electrical circuit, and this, until a new operating cycle.

  1. Automatische Hebevorrichtung (1) für Haushaltsabwässer, die für den Anschluß an einen Ablauf bestimmt ist und eine automatisch in Abhängigkeit vom Pegel der abzulassenden Flüssigkeit gesteuerte Saugpumpe (5) umfaßt, dadurch gekennzeichnet, daß sie unten einen nach oben gerichteten Kanal (2) für die Zuleitung von abzuführendem Wasser mit einem bis zu einem den Gipfel bildenden Krümmer (3) deutlich abnehmenden Querschnitt, wonach ein Kanal (4) mit starker Neigung und größerem Querschnitt folgt, der am Körper der Saugpumpe (5) mündet, und einen Miniaturschwimmer (6) umfaßt, der unmittelbar vor jenem Krümmer (3) an der engsten Stelle zur Steuerung eines elektrischen Kontaktes angeordnet ist, der die Betätigung jener Saugpumpe (5) bestimmt, wenn der für die Entleerung erforderliche Pegel erreicht ist, wobei jener abnehmende Querschnitt einen Venturi-Effekt bestimmt, der zusammen mit der Ansaugung durch die arbeitende Pumpe eine ganz und gar vollständige Entleerung gewährleistet, selbst bei einer sehr geringen Menge, beispielsweise von einer kaum aufgedrehten Handdusche, wonach jener Miniaturschwimmer (6) in die Ruheposition zurückkehrt und bis zu einem neuen Arbeitszyklus jene Saugpumpe abschaltet.
