Description

Die Erfindung betrifft eine Vorrichtung zum Aufsaugen von einzusammelnden Partikeln mit mindestens einer Sammelkammer zum Ansammeln der Partikel und mindestens einer Aufnahmekammer für Saugmittel, wobei die Sammelkammer und die Aufnahmekammer durch eine Trennwand voneinander separiert sind, die eine Eintrittsöffnung für einen Luftstrom von der Sammelkammer zu den Saugmitteln aufweist.The invention relates to a device for sucking up particles to be collected, with at least one collecting chamber for collecting the particles and at least one receiving chamber for suction means, the collecting chamber and the receiving chamber being separated from one another by a partition wall which forms an inlet opening for an air flow from the collecting chamber to the suction means having.

In der Praxis kann insbesondere bei ultrakompakten Staubsaugern, vorzugsweise Bodenstaubsaugern, deren Saugleistung zu niedrig sein. Dies kann beispielsweise durch eine verwinkelte Führung des Saugluftstroms durch die äußerst kompakte Anordnung der einzelnen Bauteile im Inneren des Gehäuses solcher Staubsauger herrühren. Weiterhin können in die Chassis eines solchen Staubsaugers aufgrund des geringen Platzangebots oftmals nur leistungsschwächere Gebläseaggregate bzw. Saugaggregate angebracht werden, die gegenüber herkömmlichen, größeren Staubsaugertypen geringere Saugleistungen aufweisen.In practice, especially in the case of ultra-compact vacuum cleaners, preferably floor vacuum cleaners, their suction power may be too low. This can result, for example, from an angled guidance of the suction air flow through the extremely compact arrangement of the individual components inside the housing of such vacuum cleaners. Furthermore, due to the limited space available, often only less powerful blower units or suction units can be installed in the chassis of such a vacuum cleaner, which have lower suction power than conventional, larger types of vacuum cleaner.

Die Druckschriften DE 198 02 345 A1 sowie EP 0 636 336 A1 betreffen geräuschdämpfend ausgestaltete Staubsauger. Die DE 44 15 005 A1 offenbart einen beutellosen Staubsauger. Ein weiteres Beispiel für einen Staubsauger ist aus der GB 2 342 596 A bekannt.The pamphlets DE 198 02 345 A1 such as EP 0 636 336 A1 relate to noise-reducing vacuum cleaners. The DE 44 15 005 A1 discloses a bagless vacuum cleaner. Another example of a vacuum cleaner is from the GB 2 342 596 A known.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Aufsaugen von einzusammelnden Partikeln bereitzustellen, deren Saugleistung selbst bei kompakter Bauweise verbessert ist. Diese Aufgabe wird durch einen Staubsauger mit den Merkmalen des Anspruchs 1 gelöst. Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art insbesondere dadurch gelöst, daß die Trennwand als Eintrittsöffnung zur Ankopplung der Sammelkammer an Saugmittel der Aufnahmekammer einen Luftleittrichter aufweist, dessen Eintrittsfläche den wesentlichen Teil der Trennwandfläche bildet.The invention has for its object to provide a device for sucking up particles to be collected, the suction power is improved even with a compact design. This object is achieved by a vacuum cleaner with the features of claim 1. This object is achieved in a device of the type mentioned in particular in that the partition has an air guide funnel as an inlet opening for coupling the collection chamber to the suction means of the receiving chamber, the inlet surface of which forms the essential part of the partition wall surface.

Dadurch, daß die Trennwand als Eintrittsöffnung einen Luftleittrichter aufweist, dessen Eintrittsfläche den wesentlichen Teil der Trennwandfläche bildet, wird ein zu großer Druckverlust des Luftstroms vom Sammelraum bzw. der Sammelkammer zu den Saugmitteln weitgehend vermieden. Weiterhin wird dadurch eine zu stark beeinträchtigende Geräuschentwicklung weitgehend vermieden. Denn je größer die Eintrittsfläche des Luftleittrichters gewählt ist, desto weniger Widerstand wird dem zu den Saugmitteln gerichteten Luftstrom entgegengesetzt. Dadurch sind weitaus weniger Luftverwirbelungen in Richtung des Sammelraums möglich. Insgesamt läßt sich verbessert ein gerichteter Luftstrom vom Sammelraum durch den Luftleittrichter zu den Saugmitteln bereitstellen.Characterized in that the partition wall has an air guide funnel as the inlet opening, the inlet surface of which forms the essential part of the partition wall surface, an excessive pressure loss of the air flow from the collecting space or the collecting chamber to the suction means is largely avoided. This also largely avoids excessive noise. This is because the larger the inlet area of the air guide funnel is chosen, the less resistance is opposed to the air flow directed to the suction means. As a result, far less air turbulence in the direction of the collecting space is possible. Overall, a directed air flow from the collecting space through the air guide funnel to the suction means can be improved.

Figur 1 zeigt schematisch in Draufsicht die Anordnung der wesentlichen Komponenten eines Bodenstaubsaugers SS, der nach dem erfindungsgemäßen Prinzip ausgebildet ist. Er weist an der einen Stirnseite seines Gehäuses GH eine Eintrittsöffnung EO mit vorzugsweise kreisrundem Querschnitt zum Ansaugen von Saugluft SL auf. Im Gehäuse hinter dieser Eintrittsöffnung EO ist eine erste Sammelkammer bzw. ein Sammelraum SR vorgesehen, der der Ansammlung von anzusaugenden Partikeln bzw. Teilchen, insbesondere Schmutzpartikeln oder Staubteilchen, dient. Hier im Ausführungsbeispiel von Figur 1 ist im Sammelraum SR ein Filterbeutel bzw. Staubbeutel PF zur Aufnahme der von außen durch die Eintrittsöffnung EO in die Sammelkammer SR hineingesaugten Schmutz oder Staubteilchen ST dient. Der Filterbeutel PF ist dabei an das ausgangsseitige Ende der etwa rohrförmigen Eintrittsöffnung EO innenseitig aufgesteckt, so daß von außen angesaugte Partikel bzw. Teilchen direkt in das Innere des Staubbeutels PF gelangen. An die Eintrittsöffnung EO ist in der Regel außen ein Staubsaugerrohr oder ein Staubsaugerschlauch angekoppelt, mit dem sich dann zum Beispiel Staubteilchen von einem Teppich aufsaugen lassen. Figure 1 shows schematically in plan view the arrangement of the essential components of a vacuum cleaner SS, which is designed according to the principle of the invention. It has an inlet opening EO on the one end face of its housing GH with a preferably circular cross section for sucking in suction air SL. A first collecting chamber or a collecting space SR is provided in the housing behind this inlet opening EO and serves to collect particles or particles to be sucked in, in particular dirt particles or dust particles. Here in the embodiment of Figure 1 a filter bag or dust bag PF is used in the collecting space SR to hold the dirt or dust particles ST sucked into the collecting chamber SR from the outside through the inlet opening EO. The filter bag PF is attached to the inside of the outlet end of the approximately tubular inlet opening EO, so that particles or particles sucked in from the outside get directly into the interior of the dust bag PF. A vacuum cleaner pipe or a vacuum cleaner hose is usually coupled to the outside of the inlet opening EO, with which, for example, dust particles can then be sucked up from a carpet.

Zweckmäßig kann es gegebenenfalls sein, in der Sammelkammer SR zwischen der Eintrittsöffnung EO und dem Staubbeutel PF zusätzlich mindestens ein Filterelement wie zum Beispiel ein Filtervlies zwischenzuschalten.It may be expedient to additionally interpose at least one filter element, such as a filter fleece, in the collecting chamber SR between the inlet opening EO and the dust bag PF.

Im Gehäuse GH des Staubsaugers SS von Figur 1 ist vom Sammelraum bzw. von der Sammel- oder Staubkammer SR eine Aufnahmekammer MR durch eine Zwischenwand TW abgetrennt. Dieser Aufnahmeraum MR dient insbesondere der Unterbringung und Lagerung von Saugmitteln, mit denen sich ein richtbarer Saugluftstrom LF durch die Eintrittsöffnung EO, dem Sammelraum SR sowie dem dort gegebenenfalls vorgesehenen Staubbeutel PF hindurch erzeugen läßt. In der Figur 1 ist dabei die Wegführung der Luftströmung LF durch das Innere des Gehäuses des Staubsaugers SS hindurch durch gestrichelte Pfeile angedeutet. Die Saugmittel sind beim Staubsauger SS primär durch ein Gebläse GB bekannter Bauart gebildet, das von einem Motor MO angetrieben wird. Die Rotorblätter des Gebläses GB sind so gestaltet, daß sie Luft von außen durch die Eintrittsöffnung EO in das Innere des Gehäuses GH einsaugen, durch den Sammelraum SR hindurchströmen lassen, anschließend durch eine Eintrittsöffnung in der Trennwand TW in den Aufnahmeraum MR absaugen, und schließlich durch Austrittsöffnungen AO im Gehäuse GH wieder nach außen ausblasen. Die ausströmende Ausblasluft ist in der Figur 1 ebenfalls mit gestrichelten Pfeilen AL angedeutet. Neben den Saugmitteln MO, MR können im Aufnahmeraum MR gegebenenfalls auch weitere Komponenten des Staubsaugers wie zum Beispiel dessen Kabeltrommel KT zum Aufwickeln eines elektrischen Anschlußkabels KA untergebracht sein.In the housing GH of the vacuum cleaner SS from Figure 1 a receiving chamber MR is separated from the collecting space or from the collecting or dust chamber SR by an intermediate wall TW. This receiving space MR is used, in particular, for the accommodation and storage of suction means with which a directional suction air flow LF can be generated through the inlet opening EO, the collecting space SR and the dust bag PF provided there, if necessary. In the Figure 1 is the routing of the air flow LF through the inside of the housing of the vacuum cleaner SS through dashed arrows indicated. In the SS vacuum cleaner, the suction means are primarily formed by a blower GB of a known type, which is driven by a motor MO. The rotor blades of the blower GB are designed such that they suck in air from the outside through the inlet opening EO into the interior of the housing GH, flow through the collecting space SR, then suction through an inlet opening in the partition TW into the receiving space MR, and finally through Blow out outlet openings AO in housing GH outwards again. The outflowing air is in the Figure 1 also indicated by dashed arrows AL. In addition to the suction means MO, MR, other components of the vacuum cleaner such as its cable drum KT for winding up an electrical connecting cable KA can also be accommodated in the receiving space MR.

Um nun eine ausreichende Saugleistung des Staubsaugers SS selbst bei kompaktem Baumaß bereitstellen zu können, wird die Eintrittsöffnung in der Trennwand TW zweckmäßigerweise an einer solchen Stelle vorgesehen, daß der Luftstrom LF von der Eintrittsöffnung EO durch den Sammelraum SR zu den Saugmitteln GB, MO hinter der Trennwand TW im Aufnahmeraum MR im wesentlichen geradlinig gerichtet führbar ist. Um eine solche gezielte Luftführung zu ermöglichen, das heißt der eingesaugten Luft eine bestimmte, vorgebbare Strömungsrichtung aufprägen zu können, ist die Einlaßöffnung in der Trennwand TW als Luftleittrichter LT ausgebildet. Dieser Luftleittrichter LT verjüngt sich ausgehend von seiner Eintrittsfläche beim Sammelraum SR in Richtung auf die Saugmittel GB, MR zu. An seine Austrittsöffnung sind unmittelbar die Saugmittel, insbesondere das Gebläse GB möglichst dicht mechanisch angekoppelt.In order to be able to provide sufficient suction power of the vacuum cleaner SS even with a compact design, the inlet opening in the partition TW is expediently provided at such a point that the air flow LF from the inlet opening EO through the collecting space SR to the suction means GB, MO behind the Partition TW can be guided in a substantially rectilinear manner in the receiving space MR. In order to enable such a targeted air flow, that is to be able to impress a certain, predeterminable flow direction on the sucked-in air, the inlet opening in the partition wall TW is designed as an air guide funnel LT. This air guide funnel LT tapers from its entry surface at the collecting space SR towards the suction means GB, MR. The suction means, in particular the blower GB, are mechanically coupled as closely as possible to its outlet opening.

Eine zweckmäßige Ausgestaltung des Luftleittrichters LT von Figur 1 zeigt Figur 2 in räumlicher Darstellung im Detail. Dort weist der Luftleittrichter LT eine im wesentlichen rechteckförmige Eintrittsfläche RE für den Luftstrom LF aus dem Staubraum SR auf. Die Eintrittsfläche RE des Luftleittrichters LT schließt dabei im wesentlichen bündig mit der ansonsten vorzugsweise plan ausgebildeten Trennwand TW ab. Die Innenwände des Luftleittrichters LT laufen dann ausgehend von dieser rechteckförmigen Außenkontur aufeinander in der Art eines Konus in Richtung auf die Saugmittel zu, die ja hinter der Trennwand TW sitzen. Dabei bilden die Innenwände des Luftleittrichters LT schließlich eine im Querschnitt etwa kreisrunde Ausgangsöffnung zur formschlüssigen Ankopplung des etwa kreisrunden Ausblasrohres des Gebläses GB. Diese Form des Luftleittrichters LT als Ankoppelkomponente für den Luftstrom LF zwischen der Sammelkammer SR und der Aufnahmekammer MR ist in der Figur 4 anhand eines Querschnittsbildes vergrößert in Seitenansicht dargestellt. Dabei endet das Innere des Luftleittrichters LT mit einer etwa kreisrunden Austrittsöffnung KRO. An diese ist über stirnseitige Abdichtungselemente GT das Gebläse GB mechanisch angekoppelt. Die Laufräder LR des Gebläses GB sind dabei stirnseitig im Abdichtelement GT geführt, wo sie sich weitgehend dicht durch den Betrieb einschleifen. Dadurch ist durch das Abdichtelement GT ein Puffer zwischen dem jeweiligen Laufrad wie zum Beispiel LR und dem Außengehäuse des Gebläses GB gebildet. Diese Verhältnisse sind nochmals zusammen mit den wichtigsten anderen Komponenten des Staubsaugers SS in der Figur 3 in Seitenansicht komplett dargestellt.A practical embodiment of the air guide funnel LT from Figure 1 shows Figure 2 in spatial representation in detail. There, the air guide funnel LT has an essentially rectangular entry surface RE for the air flow LF from the dust space SR. The entry surface RE of the air guide funnel LT is essentially flush with the otherwise preferably planar partition TW. Starting from this rectangular outer contour, the inner walls of the air guide funnel LT then converge towards one another in the manner of a cone in the direction of the suction means which are located behind the partition wall TW. The inner walls of the air guide funnel LT finally form an outlet opening which is approximately circular in cross section for the positive coupling of the approximately circular outlet pipe of the blower GB. This form of the air funnel LT as a coupling component for the air flow LF between the collecting chamber SR and the receiving chamber MR is in the Figure 4 shown enlarged in cross-sectional view in side view. The interior of the air guide funnel LT ends with an approximately circular outlet opening KRO. The blower GB is mechanically coupled to this via sealing elements GT on the end face. The impellers LR of the blower GB are guided on the end face in the sealing element GT, where they grind themselves in tightly through operation. As a result, a buffer is formed between the respective impeller such as LR and the outer housing of the blower GB by the sealing element GT. These conditions are together with the most important other components of the vacuum cleaner SS in the Figure 3 shown completely in side view.

Der Luftleittrichter LT ist nun vorteilhafterweise als Eintrittsöffnung in der Trennwand TW derart ausgebildet, daß seine Eintrittsfläche den wesentlichen Teil der Trennwandfläche bildet. Dies geht insbesondere aus Figur 2 hervor. Vorzugsweise nimmt die Eintrittsfläche RE des Luftleittrichters LT mindestens 50 %, bevorzugt zwischen 70 und 80 % der Gesamtfläche der Trennwand TW ein. Durch diese großflächige Eintrittsfläche wird ein Druckabfall des Luftstroms LF beim Ansaugen in die Saugmittel GB, MO im Aufnahmeraum MR hinein weitgehend vermieden. Der Luftleittrichter bewirkt dabei durch seine sich in Richtung auf die Saugmittel GB, MR verjüngende Form einen homogenen Übergang für den Luftstrom LF von der Sammelkammer SR zu den an der Austrittsöffnung des Luftleittrichters LT angekoppelten Saugmitteln. Denn die Ansaugröhre AR der Ansaugmittel GB, MR weist vorzugsweise einen kreisrunden Querschnitt auf, der wesentlich kleiner als die Querschnittsbreite der Trennwand TW ist. Zudem wird durch die annäherungsweise konusförmige Verjüngung des Luftleittrichters LT ein zusätzlicher Ansogeffekt für den Luftstrom LF von der Sammelkammer SR durch die Trennwand TW hindurch in den Aufnahmeraum MR bewirkt. Durch den sich in Richtung auf die Sammelkammer SR hin aufspreizenden, aufweitenden Eintrittskanal des Luftleittrichters LT wird eine Bündelwirkung bzw. Fokussierung des Luftstroms LF zusätzlich mit erreicht. Dadurch läßt sich der Luftstrom LF durch die Aufnahmekammer SR sowie dem dort eingebrachten Staubbeutel PF in gezielter Weise richten, d.h. eine Wegführung für den Luftstrom vorgeben. Insbesondere wird der Luftstrom LF durch entsprechende Ausrichtung der Eintrittsöffnung des Lichtleittrichters LT auf die gegenüberliegende Eintrittsöffnung EO der Sammelkammer SR im wesentlichen geradlinig geführt. Dadurch ist eine besonders kompakte Anordnung der Komponenten des Staubsaugers SS in dessen Gehäuse bei gleichzeitig hoher Saugleistung gewährleistet. Durch diese zum Sammelraum SR gewandte Aufspreizung bzw. Aufweitung des Luftleittrichter LT wird der angesaugten Luftströmung LF ein geringerer Luftwiderstand entgegengesetzt, wie wenn die Eintrittsöffnung in der Trennwand TW lediglich kreisrund ausgebildet wäre. Dadurch sind durch den Luftleittrichter LT auch weitgehend Luftverwirbelungen zurück in den Sammelraum SR weitgehend vermieden. Je größer dabei der Einlauftrichter des Luftleittrichters LT gewählt wird, desto weniger kommt es zu unerwünschten Reflexionen des Luftstroms LF zurück in den Staubraum SR und desto besser läßt sich die Luftströmung durch das Gebläse GB der Saugmittel aus dem Staubraum SR absaugen.The air guide funnel LT is now advantageously designed as an inlet opening in the partition wall TW such that its inlet surface forms the essential part of the partition wall surface. This is particularly the case Figure 2 forth. The inlet area RE of the air guide funnel LT preferably takes up at least 50%, preferably between 70 and 80% of the total area of the partition wall TW. A pressure drop in the air flow LF during suction into the suction means GB, MO in the receiving space MR is largely avoided by this large-area entry surface. The air guide funnel causes a homogeneous transition for the air flow LF from the collection chamber SR to the suction means coupled to the outlet opening of the air guide funnel LT due to its shape tapering in the direction of the suction means GB, MR. This is because the suction tube AR of the suction means GB, MR preferably has a circular cross section that is significantly smaller than the cross sectional width of the partition wall TW. In addition, the approximately conical tapering of the air guide funnel LT causes an additional suction effect for the air flow LF from the collecting chamber SR through the partition wall TW into the receiving space MR. The widening inlet channel of the air guide funnel LT, which widens in the direction of the collecting chamber SR, additionally achieves a bundling effect or focusing of the air flow LF. As a result, the air flow LF can be directed in a targeted manner through the receiving chamber SR and the dust bag PF introduced there, that is to say a route for the air flow can be specified. In particular, the air flow LF is guided essentially in a straight line by appropriately aligning the inlet opening of the light guide funnel LT with the opposite inlet opening EO of the collecting chamber SR. This makes the components particularly compact of the SS vacuum cleaner in its housing with high suction power at the same time. This spreading or widening of the air guide funnel LT facing the collecting space SR means that the sucked-in air flow LF is opposed to a lower air resistance than if the inlet opening in the partition wall TW were only circular. As a result, air turbulence back into the collecting space SR is largely avoided by the air guide funnel LT. The larger the inlet funnel of the air guide funnel LT is chosen, the less there are undesirable reflections of the air flow LF back into the dust space SR and the better the air flow can be sucked out of the dust space SR by the blower GB of the suction means.

Im Grund, das heißt, in der Nähe der Austrittsöffnung des Luftleittrichters LT, ist ein in Richtung der Sammelkammer SR abstehendes Eingriffschutzelement ES vorgesehen. Dieses ist vorzugsweise konusförmig gewölbt ausgebildet. Es weist insbesondere einen Rippenkörper mit Lücken zum Hindurchlassen des Luftstroms LF auf. Dieser Rippenkörper ist gegenläufig zur Verjüngung des Eintrittskanals des Luftleittrichters LT ausgerichtet. Insbesondere weist er ebenfalls eine Trichterform auf, die sich in Richtung auf die Sammelkammer SR hin aufweitet. Dadurch läßt sich ebenfalls eine Vergrößerung der Eintrittsfläche für den Luftstrom LF erzielen. Ein unerwünschter Druckverlust des Luftstroms LF beim Übergang von der Sammelkammer SR zu den Saugmitteln GB, MO ist somit weitgehend vermieden. Durch dieses rippenförmige Eingriffschutzelement ES wird der Bediener vor einem unzulässigen Hineinlangen in das Gebläse abgehalten, so daß zum Beispiel Handverletzungen durch die rotierenden Gebläseblätter weitgehend vermieden sind. Durch die spezielle Trichterform des als Motorschutzgitter wirkenden Eingriffschutzelements ES kann in vorteilhafter Weise der freie Luftquerschnitt zwischen den einzelnen Rippen größtmöglich ausgeführt werden, und somit eine relativ geringe Behinderung des Luftstroms trotz dieser zusätzlichen Schutzmaßnahme erreicht werden.Basically, that is, in the vicinity of the outlet opening of the air guide funnel LT, an engagement protection element ES projecting in the direction of the collecting chamber SR is provided. This is preferably conically curved. In particular, it has a rib body with gaps for the passage of the air flow LF. This rib body is oriented in the opposite direction to the tapering of the inlet duct of the air guide funnel LT. In particular, it also has a funnel shape that widens in the direction of the collecting chamber SR. This also makes it possible to increase the entry area for the air flow LF. An undesirable loss of pressure in the air flow LF during the transition from the collecting chamber SR to the suction means GB, MO is thus largely avoided. By means of this rib-shaped engagement protection element ES, the operator is prevented from entering the blower inadmissibly, so that, for example, hand injuries caused by the rotating blower blades are largely avoided. Due to the special funnel shape of the intervention protection element ES, which acts as a motor protection grille, the free air cross section between the individual ribs can advantageously be made as large as possible, and thus a relatively small obstruction of the air flow can be achieved despite this additional protective measure.

Zusammenfassend betrachtet ist es also zweckmäßig, aus Sicherheitsgründen in der Trichtermitte des Luftleittrichters LT, das heißt zur Öffnung zum Gebläse hin, Schutzrippen in Form eines domartigen, in Richtung der Sammelkammer SR abstehenden Eingriffsschutzelements ES vorzusehen. Neben der sich in Richtung der Sammelkammer SR domartig aufweitenden Form des Eingriffsschutzelements ES können gegebenenfalls auch anders geformte Rippenkörper ebenfalls eine Sicherheitsfunktion erfüllen.In summary, it is therefore expedient, for safety reasons, to provide protective ribs in the form of a dome-like engagement protection element ES projecting in the direction of the collecting chamber SR in the center of the funnel of the air guide funnel LT, that is to say toward the opening towards the fan. In addition to the shape of the anti-tamper element ES that widens in the direction of the collecting chamber SR if necessary, also differently shaped rib bodies also fulfill a safety function.

Zweckmäßigerweise steht das domartige Eingriffsschutzelement ES in Richtung der Sammelkammer SR lediglicht so weit ab, daß seine Außenkontur bündig mit der Eintrittsfläche RE des Luftleittrichters LT abschließt. Dadurch kann in vorteilhafter Weise zusätzlich mindestens ein Filterelement FI vor der Eintrittsöffnung des Luftleittrichters LT mittels zweier seitlich von der Eintrittsfläche RE des Luftleittrichters LT angeordneter Stegklemmen SI1, SI2 angebracht werden. Dieses Filterelement FI dient zur weiteren Reinigung der Abluft LF, die aus dem Staubraum SR abgezogen wird. Es kann insbesondere als Pollen- oder Allergikerfilter ausgebildet sein. Ein oder mehrere Filtervliese FIV werden dort vorzugsweise zwischen die beiden Hälften eines heftartigen Haltegitters HF eingeklemmt. Dies ist in der Figur 5 dargestellt, wo die übrigen Komponenten des Staubsaugers in zerlegtem Zustand dargestellt sind.The dome-like tamper protection element ES expediently protrudes from the collection chamber SR only to such an extent that its outer contour is flush with the entry surface RE of the air guide funnel LT. As a result, at least one filter element FI can advantageously also be attached in front of the inlet opening of the air guide funnel LT by means of two web clamps SI1, SI2 arranged laterally from the entry surface RE of the air guide funnel LT. This filter element FI is used for further cleaning of the exhaust air LF, which is drawn off from the dust chamber SR. It can be designed in particular as a pollen or allergy filter. One or more filter fleeces FIV are preferably clamped there between the two halves of a booklet-like holding grid HF. This is in the Figure 5 shown where the other components of the vacuum cleaner are shown disassembled.

Die Trennwand TW, der Luftleittrichter LT, und dessen vorgesetztes Eingriffsschutzelement ES sind als einstückiges Bauteil ausgebildet. Diese drei Komponenten als Einzelbauteile zu fertigen und dann mechanisch aneinander zu koppeln, ist nicht erfindungsgemäß.The partition wall TW, the air guide funnel LT, and its front engagement protection element ES are designed as a one-piece component. Manufacturing these three components as individual components and then mechanically coupling them to one another is not according to the invention.

Insbesondere kann also der Luftleittrichter fest, das heißt direkt in das Kunststoffgehäuse der Trennwand zwischen dem Staubraum und Motorraum integriert sein. Auf der Motorraumseite wird dann der Motor bzw. das zugehörige Gebläse zweckmäßig über Gummiteile an die Austrittsöffnung des Luftleittrichters angekoppelt und abgedichtet. Gemäß einer weiteren Variante kann der Luftleittrichter gegebenenfalls als Zusatzteil auf dem Motor bzw. die Gebläsehaube gesteckt werden. Die ganze Einheit wird dann über Gummiteile bekannter Art im Gerätekörper angekoppelt und abgedichtet. Bei bisherigen Bauweisen konnte die Saugluft nur um sehr starke Krümmungen aus dem Staubraum in das Gebläse gelangen. Durch den Luftleittrichter wird nun die Luft strömungsgünstig aus dem Staubraum in das Gebläse geführt. Dieser Luftleittrichter wird vorteilhafterweise im Staubraum zur Vergrößerung der Eintrittsfläche als Rechteck ausgeführt. Die Trichterform verläuft dabei vorzugsweise zügig und ohne Kontursprung auf den runden Durchmesser der Gebläseeintrittsöffnung zu. Aus Sicherheitsgründen können in der Trichtermitte (Öffnung zum Gebläse) Schutzrippen angebracht sein. Der Rippenkörper ist dabei zweckmäßigerweise gegenläufig zum Luftleittrichter nach außen in Richtung auf den Staubraum zu trichterförmig ausgebildet. Durch diese spezielle Trichterform des Motorschutzgitters (Rippenkörpers) kann der freie Luftquerschnitt zwischen den einzelnen Rippen größtmöglich ausgeführt bzw. eine relativ geringere Behinderung des Luftstromes erreicht werden. Dadurch ist insgesamt eine Steigerung der Luftleistung und somit eine Erhöhung der Abgabeleistung des jeweiligen Staubsaugers ermöglicht.In particular, the air guide funnel can thus be firmly, that is to say integrated directly into the plastic housing of the partition between the dust chamber and the engine compartment. On the engine compartment side, the engine or the associated blower is then expediently coupled and sealed via rubber parts to the outlet opening of the air guide funnel. According to a further variant, the air guide funnel can optionally be inserted as an additional part on the engine or the fan cover. The entire unit is then coupled and sealed in the device body via known rubber parts. With previous designs, the suction air could only get into the blower from the dust chamber by very large bends. The air is now guided from the dust chamber into the fan in a streamlined manner through the air guide funnel. This air guide funnel is advantageously designed as a rectangle in the dust space to enlarge the entry area. The funnel shape preferably runs quickly and without a contour jump to the round diameter of the fan inlet opening. For safety reasons, protective ribs can be attached in the middle of the funnel (opening to the fan). The rib body is there expediently designed to be funnel-shaped in the opposite direction to the air guide funnel in the direction of the dust chamber. This special funnel shape of the motor protection grille (rib body) allows the free air cross-section between the individual ribs to be made as large as possible or a relatively lower obstruction of the air flow to be achieved. This enables an overall increase in the air output and thus an increase in the output of the respective vacuum cleaner.
