Bekannt sind Staubsauger mit an ihrem Saugstutzen angeordneter, gegebenenfalls durch den in den Saugstutzen einzuführenden Saugschlauch aufstoßbarer Rückschlagklappe oder Rückschlagventil. Eine solche Rückschlagklappe verhindert das Austreten von Staub aus dem Staubbeutel bei Abnahme des Ansaugschlauches. Vacuum cleaners are known with arranged on their suction nozzle, optionally through the in the suction nozzle Suction hose to be introduced, push-open non-return valve or non-return valve. Such Non-return flap prevents dust from escaping from the dust bag when the suction hose is removed.
Die Erfindung bezieht sich auf einen Staubsauger, dessen Ansaugstutzen bei Nichtbenutzung mittels eines daran angeordneten Ventils verschlossen ist, und das Wesentliche besteht darin, daß die gleiche Einrichtung für den Auslaßstutzen vorgesehen ist. Dies hat den Vorteil, daß bei Betriebsunterbrechung kein Staub in das Gehäuse und damit in die Lager des Elektromotors gelangen kann.The invention relates to a vacuum cleaner, the suction port by means of when not in use of a valve arranged thereon is closed, and the essential thing is that the same device is provided for the outlet port. This has the advantage that no Dust can get into the housing and thus into the bearings of the electric motor.
Mit Vorteil sind die beiden Ventile derart miteinander verbunden, daß sie sich gleichzeitig öffnen und schließen, wenn eins der Ventile betätigt wird. Das Ventil am Ansaugstutzen ist dabei zweckmäßig so angeordnet, daß es beim Einführen des Saugrohres durch dieses geöffnet wird. Hierdurch werden durch Einführen des Saugrohres in den Saugstutzen beide Ventile des Ansaugstutzens und des Auslaßstutzens zwangläufig geöffnet, so daß der Luftstrom nicht gebremst und die Leistung des Staubsaugers nicht vermindert wird. Die Ventile sind dabei zweckmäßig als Klappenventile ausgebildet. Die Ventile können auch in Form einer Drosselklappe ausgebildet sein, die um eine den Rohrstutzen durchdringende Achse schwenkbar sind. Die Ventile können auch aus Ventilteller und Ventilschaft bestehen.The two valves are advantageously connected to one another in such a way that they open and simultaneously close when one of the valves is operated. The valve on the intake port is expediently arranged in such a way that that it is opened through this when the suction tube is inserted. This will be by introducing of the suction pipe in the suction port, both valves of the intake port and the outlet port inevitably opened so that the air flow is not slowed down and the performance of the vacuum cleaner is not reduced will. The valves are expediently designed as flap valves. The valves can also be in shape a throttle valve which can be pivoted about an axis penetrating the pipe socket. The valves can also consist of a valve disk and a valve stem.
Mit Vorteil sind Ventilklappen mittels Winkelhebeln und einem daran befestigten Bowdenzug miteinander verbunden.Valve flaps by means of angle levers and a Bowden cable attached to them are advantageous with one another tied together.

Nach Fig. 1 ist über das innere Ende eines Ansaugstutzens 2 einer Staubsaugergehäusekappe 3 ein Gummiring 4 gezogen, der mit einer einstückig damit verbundenen Gummirückschlagklappe 5 versehen ist, die um die Kerbe 6 gegen die Federkraft des Gummis ausschwenkbar ist, wie in strichpunktierten Linien gezeigt.According to Fig. 1, a vacuum cleaner housing cap 3 is on the inner end of a suction port 2 Pulled rubber ring 4, which is provided with an integral rubber non-return flap 5, which can be swung out around the notch 6 against the spring force of the rubber, as shown in dash-dotted lines shown.
Ein Ansaugrohr 7 eines Ansaugschlauches, das ebenso wie der Stutzen 2 schwach konisch ausgebildet ist, ist so weit in den Ansaugstutzen 2 hineinsteckbar, daß es mit seiner Kante 8 die Klappe 5 zwangsweise öffnet. Auf diese Weise kann die Klappe 5 im Be-Staubsauger, dessen AnsaugstutzenA suction pipe 7 of a suction hose which, like the nozzle 2, is slightly conical is, is so far inserted into the intake 2 that it with its edge 8, the flap 5 forcibly opens.

Nach Fig. 2 ist in einer Gehäusekappe 3 ein Ansaugstutzen 2 angeordnet, und am anderen Ende des Gehäuses 9 ist in der Kappe 10 ein Auslaßstutzen 11 eingesetzt. Ein zwischen den Teilen 3 und 9 befestigter Ring 12 trägt einen Staubbeutel 13, und Ringe 14 und 15 tragen ein Motorgehäuse 16 nebst Luftschraube. According to Fig. 2, an intake port 2 is arranged in a housing cap 3, and at the other end of the Housing 9, an outlet connection 11 is inserted in the cap 10. One attached between parts 3 and 9 Ring 12 carries a dust bag 13, and rings 14 and 15 carry a motor housing 16 and propeller.
Am Ansaugstutzen 2 ist eine Rückschlagklappe 17 bei 18 angelenkt und mit einem Hebel 19 versehen. Am Auslaßstutzen 11 ist eine Verschlußklappe 20 bei 21 angelenkt und mit einem Hebel 22 versehen. Die Hebel 19 und 22 sind durch einen Bowdenzug 23 miteinander verbunden, der die Ringe 12., 14 und 15 durchdringt.A non-return flap 17 is articulated at 18 on the intake manifold 2 and provided with a lever 19. A closure flap 20 is articulated at 21 on the outlet connection 11 and is provided with a lever 22. the Levers 19 and 22 are connected to one another by a Bowden cable 23 that connects the rings 12., 14 and 15 penetrates.
Durch das Hineinstoßen des Rohres 7 des Ansaugschlauches wird die Klappe 17 zwangsweise geöffnet und durch die Verbindung 19., 23, 22 auch zwangläufig gleichzeitig die Verschlußklappe 20 geöffnet. In den Gelenken 18 und 21 sind Schraubenfedern vorgesehen, die beim Herausziehen des Schlauchstutzens 7 beide Klappen 17 und 20 wieder verschließen, so daß weder Staub aus dem Beutel 13 nach außen noch Staub von außen durch den Stutzen 11 in den Motor gelangen kann.By pushing in the pipe 7 of the suction hose, the flap 17 is forcibly opened and through the connection 19., 23, 22 also inevitably at the same time the shutter 20 is opened. In the joints 18 and 21 coil springs are provided, which close both flaps 17 and 20 when pulling out the hose connector 7, so that neither dust from the bag 13 to the outside nor dust from the outside through the nozzle 11 into the motor can get.
Der neue Staubsauger ist somit bei Außerbetriebstellung stets verschlossen, so daß weder angesaugter Staub nach außen noch Schmutzteile von außen in den Motor gelangen können. Durch die neuen Verschlüsse werden die Sauberkeit erhöht und die Betriebsdauer des Staubsaugers verbessert.The new vacuum cleaner is therefore always closed when it is not in operation, so that neither is sucked in Dust to the outside and dirt particles from outside can get into the motor. With the new closures the cleanliness is increased and the service life of the vacuum cleaner is improved.
