Abstract

A peripheral, flexible bumper strip is provided round the housing of a vacuum cleaner, partic. intended for cleaning floors. It consists of a flexible sleeve (2), secured to the vacuum cleaner housing (1), the sleeve being inflatable. Pref. the discharge air from the vacuum cleaner blower is used for inflation of the sleeve. The latter may be fitted with one or several air outlet apertures (6), through which the discharge air is released downwards. After the air discharge, the flexibility of the sleeve permits close abutment to the vacuum cleaner housing. The positioning of the outlet apertures in the sleeve enhances noise reduction. The sleeve is so positioned that it covers the discharge aperture (3) for air from the vacuum cleaner. In this manner, the bumper sleeve is automatically inflated when the vacuum cleaner operation is started.

Description

BodenstaubsaugerCylinder vacuum cleaner

Die Erfindung betrifft einen Bodenstaubsauger mit einem außen a1n Staubsaugergeiiäuse umlaufend befestigten, elastischen Stoßschutzband.The invention relates to a cylinder vacuum cleaner with an outside a1n Elastic shock protection tape attached all around the vacuum cleaner housing.

Ein solcher Bodenstaubsauger ist durch die DE-OS 28 24 033 bekannt. Bei diesem Staubeauger ist um das Staubsaugergehäuse ein Stoßband gelegt, das ganz aus elastischem Alaterial besteht.Such a cylinder vacuum cleaner is known from DE-OS 28 24 033. In this vacuum cleaner, a bumper strip is placed around the vacuum cleaner housing, which is completely consists of elastic aluminum material.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger so auszubilden, daß für das Stoßschutzband wesentlich weniger Material benötigt wird.The invention is based on the object of designing a vacuum cleaner in such a way that that much less material is required for the shock protection tape.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindurg dadurch, daß das Stoßschutzband aus einer am Staubsaugergehäuse befestigten elastischen Hülle besteht, die aufblasbar ist. Eine solche Hülle ist relativ dünn und erfordert dementsprechend nur wenig elastisches Material. Im aufgeblasenen Zustand bildet die Hülle einen Schutzwulst, durch den das Gehäuse ausreichend gegen Stöße gesichert ist.According to the invention, the task at hand is achieved by that the shock protection tape consists of an elastic cover attached to the vacuum cleaner housing that is inflatable. Such a sheath is relatively thin and accordingly requires only a little elastic material. When inflated, the envelope forms one Protective bead by which the housing is adequately secured against impacts.

Dadurch, daß die Hülle durch die Ab luft des Staubsaugergebläses aufblasbar und mit einem Auslaßventil ersehen ist, kann nach dem Saugen die Luft aus der Hülle abgelassen wercn, so daß solch diese infolge ihrer Elastizität eng an das Gchäuse einlegt. Der Staubsauger beansprucht somit weniger Abstellraum.In that the shell is inflatable through the air from the vacuum cleaner fan and can be seen with an outlet valve, the air can be removed from the envelope after suction are drained so that these, owing to their elasticity, fit closely to the housing inserts. The vacuum cleaner therefore takes up less storage space.

Beim Anmeldugsgegenstand wird ferner auf einfache Weise eine sehr gute Dämpfung des durch das Staubsaugergebläse erzeugten Geräusches dadurch erreicht, daß die Abluft des Staubsaugergebläses durch die mit einer oder mehreren Luftaustrittsöffnungen versehene elastische Hülle nach außen abgeleitet ist.When the subject of the application is also a very simple way good attenuation of the noise generated by the vacuum cleaner fan is achieved by that the exhaust air of the Vacuum cleaner fan with one or several air outlet openings provided elastic sleeve diverted to the outside is.

Ankand eines in der Zeichnung dargestellten Ausführungsbeispiels wird der Anmeldungsgegenstalll nachfolgend näher beschrieben. Es zeigt Fig. 1 eine Draufsicht eines Bodenstaubsaugers in schematischer Darstellung, Fig. 2 einen Bodenstaubsunger im Querschnitt mit während des Betriebes aufgeblasener Hülle und Fig. 3 einen Bodenstaubsauger im Querschnitt nach dem Abschalten des Staubsaugergebläses.Ankand of an embodiment shown in the drawing is the registration counter stalll described in more detail below. 1 shows a plan view of a cylinder vacuum cleaner in a schematic representation, FIG. 2 shows a floor dust cleaner in cross section with the envelope inflated during operation and FIG. 3 shows a cylinder vacuum cleaner in cross section after switching off the vacuum cleaner fan.

An dem mit 1 bezeichneten Staubsaugergehäuse ist eine aus elastischem Material bestehende Hülle 2 umlaufend angebracht. Die Hülle 2 überdeckt eine im Staubsaugergehäuse 1 vorgesehene Ausblasorrnung 3 für die Abluft des im Staubsaugergehäuse angeordneten Gebläseaggregates 4. Ist das Gebläseaggregat 4 während eines Saugvorganges eingeschaltet, so strömt die Abluft, wie durch Pfeile 5 angedeutet, durch die Ausblasöffnung 3 und gelangt zwischen das Staubsaugergehäuse 1 und die Hülle 2, die durch den Druck der Abluft aufgeblasen wird. Hierdurch erhält die Hülle die Funktion eines Stoßschutzbandes.At the designated 1 vacuum cleaner housing is made of elastic Material existing shell 2 attached circumferentially. The shell 2 covers an im Vacuum cleaner housing 1 provided Ausblasorrnung 3 for the exhaust air in the vacuum cleaner housing arranged blower unit 4. If the blower unit 4 is during a suction process switched on, the exhaust air flows, as indicated by arrows 5, through the exhaust opening 3 and gets between the vacuum cleaner housing 1 and the cover 2, which is caused by the pressure the exhaust air is inflated. This gives the cover the function of a shock protection tape.

Auf der der Ausblasöffnung gegenüberliegenden Seite sind in der Hülle 2 eine Vielzahl von Luftaustrittsöffnungen 6 vorgesehen, durch die die Abluft des Gebläseaggregates 4 ins freie strJmen kann. Der Gesamtquerschnitt dieser Luftaustrittsöffnungen 6 ist so bemessen, daß der Abluft zwar ein gewisser Widerstand entgegengesetzt wird, so daß ein die Hülle aufblähender Druck entsteht, daß aber dieser Druck nicht so hoch wird, daß eine nennenswerte Reduzierung der Förderleistung des Ceblü.seaggregates 4 eintritt.On the side opposite the blow-out opening are in the envelope 2 a plurality of air outlet openings 6 are provided through which the exhaust air of the Blower unit 4 can flow into the open. The total cross-section of these air outlet openings 6 is dimensioned so that the exhaust air is opposed to a certain resistance, so that a pressure that inflates the envelope arises, but this pressure is not so It is high that a noticeable reduction in the delivery rate of the Ceblü.seaggregates 4 entry.

Anstelle einer Vielzahl von Luftaustrittsöffnungen 6 kann auch eine einzige Austrittsöffnung vorgesehen werden, deren Querschnitt nach den erläuterten Kriterien bemessen ist.Instead of a plurality of air outlet openings 6, one can also single outlet opening are provided whose cross-section according to the explained Criteria is measured.

Die am Staubsaugergehäuse 1 angeordnete Hülle 2 wird bei dem beschriebenen Staubsauger bei Inbetriebnahme desselben selbsttätig aufgeblasen (Fig. 2) und legt sich nach dem Abschalten des Staubsaugers wieder eng an das Gehäuse an (Fig. 3). Damit kann die während eines Saugvorganges aufgeblasene Hülle 2 ihre Funktion als Stoßschutzband voll erfüllen. Beim Abstellen des Bodenstaubsaugers in einem entp rechenden Anfbewahrungs itlum liegt die lltille 2 eng an dem Staubsaugeraehause 1 an, so daß weniger Raum beansprucht wird.The arranged on the vacuum cleaner housing 1 shell 2 is described in the Vacuum cleaner automatically inflates when it is started up (Fig. 2) and sets after switching off the vacuum cleaner to the housing again closely (Fig. 3). Thus, the envelope 2 inflated during a suction process can function as Fully meet shock protection tape. When parking the cylinder vacuum cleaner in an entp On the right, the lltille 2 lies close to the vacuum cleaner house 1 so that it takes up less space.

Dadurch, daß die Abluft des Gebläseaggregates 4 durch den zwischen dem Staubsaugergehäuse 1 und der Hülle 2 gebildeten Hohlraum nach außen abgeleitet wird, tritt eine sehr starke Dämpfung des durch das Gebläseaggregat 4 erzeugten Geräusches ein. Zur Dämpfung trägt sowohl die Elastizität der Hülle 2 als auch die Verlängerung des Weges der Abluft vom Austritt am Gebläseaggregat 4 bis zum Austritt aus der Hülle 2 bei.The fact that the exhaust air from the blower unit 4 through the between the vacuum cleaner housing 1 and the shell 2 formed cavity discharged to the outside there is a very strong damping of the generated by the blower unit 4 Noise. Both the elasticity of the shell 2 and the Extension of the path of the exhaust air from the outlet at the blower unit 4 to the outlet from the case 2.
