Description

Die Erfindung betrifft einen Staubsauger mit einem auf den Motor des Gebläseaggregates aufsteckbaren schalldämmenden Körper, welcher das Motorgehäuse unter Belassung eines Strömungsraumes umgibt.The invention relates to a vacuum cleaner with a sound-absorbing body which can be plugged onto the motor of the blower unit and which surrounds the motor housing while leaving a flow space.

Ein solcher Staubsauger ist durch das DE-GM 75 14 249 bekannt. Bei diesem Staubsauger ist ein röhrenförmig ausgebildeter Körper aus Schaumstoff über den Motor des Gebläseaggregates geschoben. Der auf der freien Stirnseite des Motors austretende Luftstrom wird mittels einer formstabilen Umlenkkappe, die auf das Motorgehäuse aufgesetzt ist, in Richtung zum Gebläse des Gebläseaggregates umgelenkt und strömt zwischen der Außenseite der Umlenkkappe und dem Schaumstroffkörper zur mit Austrittsschlitzen versehenen Rückseite des Staubsaugers. Sowohl die Umlenkkappe als auch der röhrenförmige Schaumstoffkörper beanspruchen viel Raum, so daß für die Vorratshaltung bei der Fertigung ein entsprechend hoher Bedarf an Lagerraum besteht.Such a vacuum cleaner is known from DE-GM 75 14 249. In this vacuum cleaner, a tubular body made of foam is pushed over the motor of the blower unit. The air flow exiting on the free end face of the motor is deflected towards the blower of the blower unit by means of a dimensionally stable deflection cap, which is placed on the motor housing, and flows between the outside of the deflection cap and the foam body to the rear of the vacuum cleaner provided with exit slots. Both the deflection cap and the tubular foam body take up a lot of space, so that there is a correspondingly high need for storage space for stockpiling during production.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger der eingangs beschriebenen Art so auszubilden, daß für die Vorratshaltung der für die Geräuschdämpfung am Staubsauger benötigten Teile weniger Lagerraum benötigt wird.The invention has for its object to provide a vacuum cleaner of the type described in such a way that less storage space is required for the storage of the parts required for noise reduction on the vacuum cleaner.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß der schalldämmende Körper plattenförmig ausgebildet und mit eine hutförmige Verformung zulassenden, keilförmigen Einschnitten versehen ist, welche sich vom Umfangsrand her mit ihrer Spitze zur Mitte des Körpers erstrecken. Da der plattenförmige Schalldämmkörper erst beim Einbau in den Staubsauger in seine entsprechende Raumform gebracht wird, ergibt sich bei der Lagerrung wegen der plattenförmigen Ausbildung nur ein entsprechend geringer Raumbedarf.The object is achieved according to the invention in that the sound-absorbing body is plate-shaped and is provided with a hat-shaped deformation, wedge-shaped incisions which extend from the peripheral edge with its tip to the center of the body. Since the plate-shaped soundproofing body is only brought into its corresponding spatial shape when installed in the vacuum cleaner, results only a correspondingly small space requirement due to the plate-shaped design.

Die hutförmige Verformung des schalldämmenden Körpers gelingt mittels einer den auf die freie Stirnseite des Motors aufgelegten schalldämmenden Körper übergreifenden Kappe. Eine solche Kappe wird über den schalldämmenden Körper geschoben und biegt die durch die Einschnitte gebildeten Lappen parallel zum Motorgehäuse um, so daß der schalldämmende Körper das Motorgehäuse umhüllt.The hat-shaped deformation of the sound-absorbing body is achieved by means of a cap which engages over the sound-absorbing body placed on the free end face of the motor. Such a cap is pushed over the sound-absorbing body and bends the tabs formed by the incisions parallel to the motor housing, so that the sound-insulating body envelops the motor housing.

Eine Fertigungsvereinfachung ergibt sich dadurch, daß die Kappe am Staubsaugergehäuse angeformt ist. Hierdurch erfolgt die Verformung des plattenförmigen Körpers selbsttätig beim Aufsetzen des entsprechenden Staubsaugergehäuseteiles.A simplification of production results from the fact that the cap is molded onto the vacuum cleaner housing. As a result, the deformation of the plate-shaped body takes place automatically when the corresponding vacuum cleaner housing part is put on.

Eine Erleichterung der Montage des schalldämmenden Körpers ergibt sich dadurch, daß dieser mit mindestens einer auf einen an der freien Stirnseite des Motors vorgesehenen Vorsprung passen den Aufstecköffnung versehen ist.The assembly of the sound-absorbing body is facilitated by the fact that it is provided with at least one push-fit opening that fits onto a projection provided on the free end face of the motor.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt:

FIG 1
einen Staubsauger im Schnitt,
FIG 2
eine Ausführungsform eines plattenförmigen schalldämmenden Körpers,
FIG 3
den zu einem Hut geformten schalldämmenden Körper nach FIG 2,
FIG 4

The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows:
FIG. 1
a vacuum cleaner on average,
FIG 2
one embodiment of a plate-shaped sound-absorbing body,
FIG 3
the sound-absorbing body shaped into a hat according to FIG. 2,
FIG 4
another embodiment of a plate-shaped sound-absorbing body,
FIG 5
the deformation of the sound-absorbing body according to FIG 4 by means of a slip-on cap.

Mit 1 ist ein Staubsauger bezeichnet, in dessen Gehäuse ein Staubraum 2 und ein Gebläseraum 3 ausgebildet ist. Ein im Gebläseraum 3 angeordnetes Gebläseaggregat besteht aus einem Motor 4 und einem mit diesem verbundenen Gebläse 5. Zur Geräuschdämpfung des zur freien Stirnseite des Motors 4 hin austretenden, durch Pfeile 6 angedeuteten Luftstromes ist auf der freien Stirnseite des Motors 4 ein plattenförmiger, schalldämmender Körper 7 aufgelegt. Eine an der oberen Hälfte des Staubsaugergehäuses angeformte Kappe 8 übergreift den schalldämmenden Körper 7 und verformt diesen zu einem das Motorgehäuse umschließenden Hut. Die Kappe 8 ist so bemessen, daß sich der schalldämmende Körper 7 nicht am Motorgehäuse anlegt, sondern ein Durchtrittsspalt 9 für den Luftstrom verbleibt.1 denotes a vacuum cleaner, in the housing of which a dust chamber 2 and a blower chamber 3 are formed. A blower unit arranged in the blower chamber 3 consists of a motor 4 and a blower 5 connected to it. In order to dampen the noise of the airflow emerging from the free front side of the motor 4, indicated by arrows 6, there is a plate-shaped, sound-absorbing body 7 on the free front side of the motor 4 hung up. A molded on the upper half of the vacuum cleaner housing 8 engages over the sound-absorbing body 7 and deforms it into a hat enclosing the motor housing. The cap 8 is dimensioned such that the sound-absorbing body 7 does not abut the motor housing, but a passage gap 9 remains for the air flow.

Wie aus den Figuren2 und 4 zu erkennen ist, ist der schalldämmende Körper 7 plattenförmig ausgebildet und mit keilförmigen Einschnitten 10 versehen. Diese Einschnitte 10 ermöglichen eine Verformung des schalldämmenden Körpers 7 zu einem Hut. In FIG 3 ist der schalldämmende Körper 7 beispielsweise durch überlappendes Verbinden der Seitenkanten der Einschnitte 10 zu einem Hut geformt, der auf den Motor 4 aufgesetzt werden kann. Die Verformung zu einem Hut geschieht somit in einen gesonderten Arbeitsgang.As can be seen from FIGS. 2 and 4, the sound-absorbing body 7 is plate-shaped and provided with wedge-shaped incisions 10. These incisions 10 allow the sound-absorbing body 7 to be deformed into a hat. In FIG. 3, the sound-absorbing body 7 is formed into a hat, for example by overlapping connection of the side edges of the incisions 10, which can be placed on the motor 4. The deformation to a hat is done in a separate operation.

Wie aus der Darstellung der FIG 5 erkennbar, kann die entsprechende Verformung des schalldämmenden Körpers 7 auch durch Überstülpen einer Kappe 8 über den in plattenförmiger Gestalt auf die freie Stirnseite des Motors 4 aufgelegten schalldämmenden Körper 7 erfolgen. Um ein Verrutschen des auf die Stirnseite des Motors 4 aufgelegten Körpers 7 zu vermeiden, weist dieser eine Aufstecköffnung 11 auf, mit der er auf einen entsprechenden Vorsprung 12, z.B. einer Lagerkappe des Motors 4 aufsteckbar ist.As can be seen from the illustration in FIG. 5, the corresponding deformation of the sound-absorbing body 7 can also take place by fitting a cap 8 over the sound-absorbing body 7 placed in a plate shape on the free end face of the motor 4. In order to prevent the body 7 placed on the end face of the motor 4 from slipping, it has a push-on opening 11, by means of which it fits onto a corresponding projection 12, e.g. a bearing cap of the motor 4 can be plugged on.

Ist die Kappe 8 am Staubsaugergehäuse vorgesehen, dann geschieht die Verformung des schalldämmenden Körpers 7 mit dem Aufsetzen der entsprechenden Gehäusehälfte des Staubsaugers. Es ist somit kein gesonderter Arbeitsgang notwendig.If the cap 8 is provided on the vacuum cleaner housing, then the deformation of the sound-absorbing body 7 takes place with the Put on the corresponding housing half of the vacuum cleaner. No separate work step is therefore necessary.
