Description

Die Erfindung betrifft einen mit Druckluft betriebenen Staubsauger, bei welchem als Saugelement zwei oder mehr parallel geschaltete Strahlpumpen dienen.The invention relates to a compressed air operated one Vacuum cleaner in which two or more jet pumps connected in parallel are used as the suction element.

Gemäß der Erfindung wird die Leistung des Staubsaugers dadurch bedeutend verbessert, daß die Strahlpumpen bisher nicht bekannte Abmessungen erhalten.According to the invention, the performance of the vacuum cleaner significantly improved by the fact that the jet pumps are given previously unknown dimensions.

Di© besonderen neuen Merkmale der Erfindung sind dadurch gekennzeichnet, daß das Verhältnis des Querschnitts des Ansaugstutzens zu der Summe der kleinsten Querschnitte der Mischrohre der Strahlpumpen gleich 3,5 bis 3,8 ist und daß der Abstand der Druckluftdüsenmündung vom inneren Ende des konischen Teils jedes Mischrohres, der eine Konizität von 10° aufweist, drei Viertel der Länge des konischen Teils beträgt, wobei das Verhältnis des größeren zum kleineren Durchmesser des konischen Teils des Mischrohres 2,16 ist.These are special new features of the invention characterized in that the ratio of the cross section of the suction port to the sum of the smallest Cross-sections of the mixing tubes of the jet pumps is equal to 3.5 to 3.8 and that the distance between the compressed air nozzle mouth from the inner end of the conical part of each mixing tube, which has a conicity of 10 ° is three quarters of the length of the conical part, the ratio of the larger to the smaller Diameter of the conical part of the mixing tube is 2.16.

Diese Größenverhältnisse ermöglichen es, unter Beibehaltung des meist völlig ausreichenden Vakuums, wie es bei den bekannten Konstruktionen erzielt wird, den Luftverbrauch bis 21 °/o zu verringern.These proportions make it possible, while maintaining the usually completely sufficient vacuum, as it is achieved with the known constructions to reduce the air consumption to 21%.

Der Gegenstand der Erfindung ist schematisch in der Zeichnung in den Abb. I und II dargestellt. Dabei zeigtThe subject of the invention is shown schematically in the drawing shown in Figs. I and II. It shows

Abb. I einen erfmdungsgemäßen Staubsauger im Längsschnitt,Fig. I a vacuum cleaner according to the invention in longitudinal section,

Abb. II eine Draufsicht auf das stehende Gerät.Fig. II is a top view of the standing device.

Der Preßluftstaubsauger hat bei der gezeigten Ausführungsform als Saugelement zwei Strahlpumpen 1, welche am Deckel 2 im Behälter 3 innerhalb des Staubbeuteis 4 angeordnet sind. Die Druckluft wird durch die Rohrleitung 5 den Strahlpumpen zugeführt. Zum Aufstecken des Saugschlauches ist der Stutzen 6 vorgesehen. Den kleinsten Querschnitt des Mischrohres jeder Strahlpumpe bildet Teil 7.In the embodiment shown, the compressed air vacuum cleaner has two jet pumps 1 as suction element, which are arranged on the cover 2 in the container 3 within the dust bag 4. The compressed air is fed through the pipe 5 to the jet pumps. The connector 6 is provided for attaching the suction hose. Part 7 forms the smallest cross-section of the mixing tube of each jet pump.
