Description

Beschreibungdescription
Staubsauger mit FliehkraftabscheiderVacuum cleaner with centrifugal separator
Die Erfindung betrifft einen Staubsauger mit einem Fliehkraftabscheider gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a vacuum cleaner with a centrifugal separator according to the preamble of claim 1.
Es gibt bereits verschiedene Ausführungen von so genannten beutellosen Staubsaugern, welche mit Fliehkraftabscheidern arbeiten. Bei einem großen Teil dieser Staubsauger ist der Staubsammelbehälter direkt mit dem Fliehkraftabscheider kombiniert und als ein Bauteil ausgeführt. Der Abscheider befindet sich beispielsweise im Inneren des Staubsammelbehälters, der Schmutz wird in dem den Abscheider umgebenden Behälter gesammelt. Dieser Aufbau hat den Nachteil, dass bei einer Entnahme des Staubsammelbehälters zum Ausleeren des Staubes auch der Fliehkraftabscheider mit entnommen wird. Hierdurch wird das gesamte zu entnehmende Teil recht schwer und unhandlich. Außerdem ist der Aufbau des kombinierten Bauteils recht komplex und damit teuer in der Entwicklung.There are already various designs of so-called bagless vacuum cleaners, which work with centrifugal separators. For a large part of these vacuum cleaners, the dust collector is combined directly with the centrifugal separator and designed as one component. The separator is located, for example, inside the dust collector, the dirt is collected in the container surrounding the separator. This structure has the disadvantage that when a removal of the dust collection container for emptying the dust and the centrifugal separator is removed with. As a result, the entire part to be removed is quite heavy and unwieldy. In addition, the structure of the combined component is quite complex and therefore expensive to develop.
Aus diesem Grund gibt es auch nach dem Fliehkraftprinzip arbeitende Staubsauger, die einen vom Abscheider separierten Staubsammelbehälter aufweisen. Bei diesen Modellen sind sowohl die Staubsammelbehälter als auch die Fliehkraftabscheider im Allgemeinen sehr einfach ausgeführt. Oftmals werden diese Staubsauger entwickelt, indem herkömmliche staubbeutelbehaftete Staubsauger weiterentwickelt werden. Hierbei ist Priorität, dass möglichst viele Bauteile des herkömmlichen Staubsaugers ohne Veränderungen übernommen werden können. Aufgabe der Erfindung war es daher, einen Staubsauger mit einem entnehmbaren Staubsammelbehälter so zu entwickeln, dass der Staubsammelbehälter separat vom Fliehkraftabscheider entnehmbar ist, gleichzeitig aber ein möglichst einfacher, kostengünstiger und bedienerfreundlicher Aufbau des Staubsaugers beibehalten werden kann. Gelöst wird diese Aufgabe gemäß der Erfindung durch einen Staubsauger mit einem Fliehkraftabscheider mit den Merkmalen von Anspruch 1. Weitere vorteilhafte Ausführungsformen sind Bestandteil der Unteransprüche im Zusammenhang mit der Beschreibung und den Zeichnungen.For this reason, there are also working on the centrifugal force vacuum cleaner, which have separated from the separator dust collector. In these models, both the dust collectors and centrifugal separators are generally very simple. Often, these vacuum cleaners are developed by further developing conventional vacuum bagged vacuum cleaners. Here, priority is that as many components of the conventional vacuum cleaner can be adopted without changes. The object of the invention is therefore to develop a vacuum cleaner with a removable dust collector so that the dust collector is removed separately from the centrifugal separator, but at the same time as simple, inexpensive and user-friendly design of the vacuum cleaner can be maintained. This object is achieved according to the invention by a vacuum cleaner with a centrifugal separator with the features of claim 1. Further advantageous embodiments are part of Subclaims in connection with the description and the drawings.
Erfindungsgemäß steht der Fliehkraftabscheider in einem sogenannten beutellosen Staubsauger mit dem Deckel des Staubsaugers in Verbindung. Er ist also am Deckel gehaltert und kann zusammen mit diesem entnommen werden. Dadurch, dass der Fliehkraftabscheider im Staubsaugerdeckel gehaltert ist, kann der Staubsaugerdeckel den Fliehkraftabscheider vollständig überdecken, sodass an den Abscheider keine besonderen Designanforderungen zu stellen sind. Das Erscheinungsbild des Staubsaugers wird in erster Linie durch den Deckel geprägt, welcher als Designteil auszubilden ist. Die unter dem Deckel angeordneten Bauteile können sehr einfach geformt sein. Dadurch kann der Fliehkraftabscheider unter rein funktionellen Gesichtspunkten entwickelt werden. An seinen Aufbau bestehen keine optischen Anforderungen. Hierdurch werden Konstruktions- und Herstellkosten eingespart. Auch bei einer Weiterentwicklung des Staubsaugers, welche beispielsweise aufgrund eines geänderten Zeitgeschmacks erfolgt, muss nur der Staubsaugerdeckel verändert werden, der darunter befindliche Fliehkraftabscheider, welcher als rein funktionelles Teil ausgebildet ist, kann in der bestehenden Form übernommen werden. Besonders vorteilhaft ist die Verbindung von Fliehkraftabscheider und Staubsaugerdeckel, wenn der Fliehkraftabscheider oberhalb des Staubsammelbehälters angeordnet ist. In diesem Fall wird der am Deckel befestigte Fliehkraftabscheider automatisch mit dem Staubsaugerdeckel vom Staubsammelbehälter abgenommen, sobald der Staubsauger zum Entleeren des Staubsammelbehälters geöffnet wird. Beim Öffnen des Staubsaugers bleibt der Fliehkraftabscheider also fest in seiner vorgesehenen Position, während der Staubsammelbehälter zum Entleeren einfach entnommen werden kann, wie der Bediener dies von einem Staubsauger mit herkömmlichem Staubbeutel gewohnt ist. Hierdurch wird auch der beutellose Staubsauger sehr bedienerfreundlich. Vorzugsweise ist der Fliehkraftabscheider lösbar am Staubsaugerdeckel befestigt. Dadurch kann der Fliehkraftabscheider einfach vom Deckel getrennt werden, falls er beispielsweise aufgrund einer Verstopfung selbst gewartet werden muss. Die lösbare Befestigung kann vorzugsweise in einer Rastverbindung bestehen. Eine Rastverbindung, bestehend aus Rastlasche und Rasthaken ist eine sehr kostengünstige einfach zu montierende Befestigung und hilft somit die Herstellkosten gering zu halten. Die lösbare Verbindung kann aber auch als Schraubverbindung ausgeführt sein, was sich insbesondere dann anbietet, wenn der Staubsauger zu einem höherklassigen Modell gehört und einen robusteren Eindruck beim Bediener machen soll.According to the invention, the centrifugal separator is connected to the lid of the vacuum cleaner in a so-called bagless vacuum cleaner. So he is supported on the lid and can be removed together with this. The fact that the centrifugal separator is held in the vacuum cleaner cover, the vacuum cleaner cover can completely cover the centrifugal separator, so that no special design requirements are to be placed on the separator. The appearance of the vacuum cleaner is primarily characterized by the lid, which is to be designed as a design part. The arranged under the lid components can be shaped very easily. As a result, the centrifugal separator can be developed under purely functional aspects. There are no optical requirements for its structure. This saves design and manufacturing costs. Even with a further development of the vacuum cleaner, which takes place, for example, due to a changed zeitgeschmacks, only the vacuum cleaner cover must be changed, the underlying centrifugal, which is designed as a purely functional part, can be adopted in the existing form. Particularly advantageous is the combination of centrifugal separator and vacuum cleaner cover when the centrifugal separator is arranged above the dust collection container. In this case, the centrifugal separator attached to the lid is automatically removed from the dust collector with the vacuum cleaner lid when the vacuum cleaner is opened to empty the dust collector. When opening the vacuum cleaner so the centrifugal separator remains fixed in its intended position, while the dust collector can be easily removed for emptying, as the operator is used to this from a vacuum cleaner with a conventional dust bag. As a result, the bagless vacuum cleaner is very user-friendly. Preferably, the centrifugal separator is releasably attached to the vacuum cleaner cover. This allows the centrifugal separator easily from the lid be disconnected, for example, if he has to be self-serviced due to a blockage. The releasable attachment may preferably consist in a latching connection. A locking connection, consisting of locking tab and locking hooks is a very cost-effective easy to install attachment and thus helps to keep the manufacturing costs low. The detachable connection can also be designed as a screw connection, which is particularly useful when the vacuum cleaner belongs to a higher-class model and should make a more robust impression on the operator.
In einer weiteren vorteilhaften Ausführungsform sind Fliehkraftabscheider und Staubsaugerdeckel einteilig ausgebildet. Dieses einstückige Kombinationsteil lässt sich vorzugsweise aus Kunststoff in einem Schritt in einem Spritzgussverfahren herstellen. Dies ermöglicht eine besonders kostengünstige Produktion und bietet sich vorzugsweise für eine günstige Modelllinie des Staubsaugers an.In a further advantageous embodiment centrifugal separator and vacuum cleaner cover are integrally formed. This one-piece combination part can be preferably made of plastic in one step in an injection molding process. This allows a particularly cost-effective production and preferably lends itself to a favorable model line of the vacuum cleaner.
In einer weiteren vorteilhaften Ausführungsform ist der den Fliehkraftabscheider tragende Deckel des Staubsaugers schwenkbar am Staubsaugerunterteil befestigt. Dadurch können Staubsaugerdeckel und Fliehkraftabscheider zum Entleeren des Staubsammelbehälters einfach bedienerfreundlich weggeklappt werden und bleiben weiterhin mit dem Unterteil in Verbindung, so dass keine losen Teile zwischendurch abgesetzt und anschließend wieder eingesetzt werden müssen. Vorzugsweise weist der Staubsauger zwei parallel betriebene Fliehkraftabscheider auf, wobei beide Fliehkraftabscheider direkt oder indirekt mit dem Staubsaugerdeckel in Verbindung stehen. Hierdurch kann die Abscheideleistung des Staubsaugers erhöht werden und der Staubsauger leiser betrieben werden als nur mit einem Abscheider. Insbesondere können aber vorzugsweise zwei kleinere Abscheider parallel betrieben werden. Bei einer Befestigung am Deckel ermöglicht die Verwendung kleinerer Abscheider ein kompakteres Gesamtelement als es nur ein Fliehkraftabscheider ermöglichen würde, der um eine entsprechende Leistung zu bringen, deutlich größer ausgebildet sein müsste. Auch die Verteilung des Gewichts am Deckel ist gleichmäßiger, wenn zwei kleinere Fliehkraftabscheider an ihm befestigt sind. Dadurch kann der Deckel einfacher verschwenkt werden.In a further advantageous embodiment of the centrifugal separator-carrying lid of the vacuum cleaner is pivotally mounted on the vacuum cleaner base. As a result, vacuum cleaner lid and centrifugal separator for emptying the dust collector can be easily folded user-friendly and remain with the lower part in conjunction so that no loose parts dropped in between and then reused. The vacuum cleaner preferably has two centrifugal separators operated in parallel, with both centrifugal separators being connected directly or indirectly to the vacuum cleaner cover. As a result, the separation efficiency of the vacuum cleaner can be increased and the vacuum cleaner operated quieter than only with a separator. In particular, however, two smaller separators can preferably be operated in parallel. When attached to the lid, the use of smaller separators allows a more compact overall element than would allow only a centrifugal separator, which would have to be made significantly larger in order to bring about a corresponding performance. Also, the distribution of weight on the lid is more uniform, if two smaller centrifugal separators are attached to it. This allows the lid to be pivoted easier.

Figur 1 zeigt anhand einer Schnittdarstellung das Innere eines erfindungsgemäßen Staubsaugers. An einem Staubsaugerunterteil 1 ist ein Staubsaugerdeckel 2 über eine Schwenkachse 3 schwenkbar angebracht. Im Inneren des Staubsaugers ist ein Gebläse 4 zum Ansaugen der Luft, ein Fliehkraftabscheider 5 zum Abscheiden des Staubs aus der angesaugten staubbeladenen Luft und eine Staubsammelbox 6 zum Sammeln des vom Fliehkraftabscheider 5 abgeschiedenen Staubs angeordnet. Die staubbeladene Luft, welche über ein nicht dargestelltes Saugrohr eingesaugt wird, tritt über den Eintrittsbereich 7 in den Fliehkraftabscheider 5 sowie einen in der Darstellung nicht zu sehenden zweiten spiegelbildlich zum Fliehkraftabscheider 5 aufgebauten Fliehkraftabscheider ein. Im Fliehkraftabscheider 5 und entsprechend in dem nicht gezeigten zweiten Abscheider wird die einströmende Luft in eine Drehbewegung versetzt, wodurch der Staub über Fliehkräfte an die Wand des Fliehkraftabscheiders 5 gedrängt wird. An der dem Eintrittsbereich 7 gegenüberliegenden Seite des Fliehkraftabscheiders 5 befindet sich ein Auslass 8 für den abgeschiedenen Staub.Figure 1 shown vacuum cleaner and Figure 3: a detail section corresponding to that shown in Figure 2 but with a different fastening. Figure 1 shows a sectional view of the interior of a vacuum cleaner according to the invention. On a vacuum cleaner base 1, a vacuum cleaner cover 2 is pivotally mounted about a pivot axis 3. Inside the vacuum cleaner, a fan 4 for sucking the air, a centrifugal separator 5 for separating the dust from the sucked dust-laden air, and a dust collecting box 6 for collecting the dust separated from the centrifugal separator 5 are disposed. The dust-laden air, which is sucked in via a suction pipe, not shown, enters the centrifugal separator 5 via the inlet region 7 and a second mirror-image centrifugal separator 5, which is not shown in the illustration. In the centrifugal separator 5 and correspondingly in the second separator, not shown, the incoming air is set in a rotational movement, whereby the dust is forced by centrifugal forces to the wall of the centrifugal separator 5. At the inlet side 7 opposite side of the centrifugal separator 5 is an outlet 8 for the separated dust.
Der Auslass 8 ist in dem in Figur 2 gezeigten Detailausschnitt zu sehen, bei dem die Staubbox 6 weggelassen wurde und deshalb der gesamte Fliehkraftabscheider 5 sichtbar wird. Die vom Staub gereinigte Luft verlässt über einen nicht dargestellten lufteintrittseitig im Zentrum des Fliehkraftabscheiders 5 angeordneten Luftaustritt den Fliehkraftabscheider 5 und gelangt über einen in der Figur nicht sichtbaren Feinstaubfilter in den Unterdruckraum 9, von dem aus die gereinigte Luft über das Gebläse 4 an die Umgebung abgegeben wird. Erfindungsgemäß ist der Fliehkraftabscheider 5 über eine Rastverbindung 10 an dem Staubsaugerdeckel befestigt. Die Rastverbindung 10 weist einen Rasthaken 11 auf, der am Fliehkraftabscheider 5 angebracht ist und der in eine am Staubsaugerdeckel 2 vorgesehene Rastlasche 12 eingreift. Über die Rastverbindung 10 ist der Fliehkraftabscheider 5 also lösbar am Staubsaugerdeckel 2 befestigt und kann zum Öffnen des Staubsaugers zusammen mit dem Staubsaugerdeckel 2 weggeschwenkt werden. Zum Reinigen des Fliehkraftabscheiders 5 lässt sich die Rastverbindung 10 öffnen, so dass der Fliehkraftabscheider 5 entnommen werden kann. Figur 3 zeigt ebenso wie Figur 2 einen Detailausschnitt aus einem erfindungsgemäßen Staubsauger, bei dem insbesondere die Verbindung von Fliehkraftabscheider 5 und Staubsaugerdeckel 2 zu sehen ist. Allerdings handelt es sich hier um ein weiteres Ausführungsbeispiel, bei dem die Verbindung über eine Schraubverbindung 13 realisiert ist. Hierfür weisen Staubsaugerdeckel 2 und Fliehkraftabscheider 5 Befestigungselemente auf, die über eine Schraube verbunden werden. Da eine Entnahme des Fliehkraftabscheiders 5 nur im Ausnahmefall notwendig ist, wenn der Fliehkraftabscheider 5 verstopft ist, kann auch eine derartige, etwas stabilere Befestigung sinnvoll sein. The outlet 8 can be seen in the detail shown in Figure 2, in which the dust box 6 has been omitted and therefore the entire centrifugal separator 5 is visible. The purified air from the dust leaves via a non-illustrated air inlet side in the center of the centrifugal 5 arranged air outlet the centrifugal 5 and passes through a not visible in the figure fine dust filter in the vacuum chamber 9, from which the purified air through the fan 4 to the environment becomes. According to the centrifugal separator 5 is attached via a snap-in connection 10 on the vacuum cleaner cover. The latching connection 10 has a latching hook 11, which is attached to the centrifugal separator 5 and which engages in a provided on the vacuum cleaner cover 2 locking tab 12. About the locking connection 10 of the centrifugal 5 is therefore releasably attached to the vacuum cleaner cover 2 and can be pivoted away to open the vacuum cleaner together with the vacuum cleaner cover 2. To clean the centrifugal separator 5, the locking connection 10 can be opened, so that the centrifugal separator 5 can be removed. Figure 3 shows as well as Figure 2 shows a detail of a vacuum cleaner according to the invention, in which in particular the connection of centrifugal 5 and vacuum cleaner cover 2 can be seen. However, this is a further embodiment in which the connection is realized via a screw connection 13. For this purpose, vacuum cleaner cover 2 and centrifugal 5 have fasteners that are connected by a screw. Since a removal of the centrifugal separator 5 is necessary only in exceptional cases when the centrifugal separator 5 is clogged, such a slightly more stable attachment may be useful.
