Description

Die vorliegende Erfindung betrifft ein Sauggerät für einen Sauger, mit einem Gehäuse, in dem ein Fliehkraftabscheider zur Abscheidung von Schmutzteilchen und/oder Flüssigkeit aus einem das Sauggerät durchströmenden Prozessluftstrom sowie ein Schwimmer vorgesehen sind.The present invention relates to a suction device for a nipple, with a housing in which a centrifugal separator for the separation of dirt particles and / or liquid from a suction device flowing through the process air stream and a float are provided.

Ein Sauger umfasst üblicherweise eine Saugdüse, einen Saugkanal und ein Sauggerät. Der Prozessluftstrom, der von einem im Sauggerät vorgesehenen, von einem Motor angetriebenen Radiallüfter erzeugt wird, tritt durch die Saugdüse in den Saugkanal ein, und strömt weiter in das Sauggerät. Der in das Sauggerät eintretende Prozesstuftstrom ist mit Feuchtigkeit, Schaum, Schmutz und/oder Staub durchsetzt. Im Sauggerät wird der Prozessluftstrom einer Fliehkraftabscheidung unterzogen, so dass Flüssigkeit und/oder Staub und Schmutz in einem im Sauggerät vorgesehenen Sammelbehälter aufgefangen werden.A sucker usually comprises a suction nozzle, a suction channel and a suction device. The process air flow, which is generated by a provided in the suction device, driven by a motor radial fan, enters through the suction nozzle in the suction channel, and continues to flow into the suction device. The process stream entering the vacuum cleaner is permeated with moisture, foam, dirt and / or dust. In the suction device, the process air flow is subjected to centrifugal separation, so that liquid and / or dust and dirt are collected in a collecting container provided in the suction device.

Die DE 30 34 400 A1 beschreibt ein Sauggerät für einen Nass-Trocken-Sauger, mit einem Schwimmer, d.h. einer Einrichtung zur Füllstandsabschaltung. Das bekannte Sauggerät weist ferner einen Fliehkraftabscheider auf, der im Wesentlichen als nach unten, d.h. zum Boden des Sammelbehälters hin, offene kreiszylindrische Innenwand ausgestaltet ist. Bei dieser Ausgestaltung besteht die Gefahr, dass sich Reste von Staub und Schmutz am Schwimmer absetzen und dessen vertikale Beweglichkeit beeinträchtigen. Ferner besteht die Gefahr der Schaumbildung, bspw. falls die aufgenommene Flüssigkeit ein Reinigungsmittel enthält. Der Schaum kann vom Prozessluftstrom mitgerissen werden bzw. sich bei hohem Füllstand im Sammelbehälter mit dem Prozessluftstrom vermischen. Damit besteht die Gefahr, dass die im Schaum enthaltene Feuchtigkeit in den Bereich des Gebläsemotors gelangt, und nicht im dafür vorgesehenen Behälter abgeschieden wird. Schließlich können aufgrund der hohen Geschwindigkeit des Prozessluftstroms auch Flüssigkeitsreste mit angesaugt und, zusammen mit Staub und Schmutz, mit der Prozessluft aus dem Sauggerät ausgeblasen werden.The DE 30 34 400 A1 describes a suction device for a wet-dry vacuum, with a float, ie a device for filling level shutdown. The known suction device further comprises a centrifugal separator, which is configured substantially as down, ie towards the bottom of the collecting container, open circular cylindrical inner wall. In this embodiment, there is a risk that settle remnants of dust and dirt on the float and affect its vertical mobility. There is also the risk of foaming, for example if the liquid absorbed contains a cleaning agent. The foam can be entrained by the process air flow or mix at high level in the sump with the process air flow. There is a risk that the moisture contained in the foam gets into the area of the fan motor and is not deposited in the container provided for this purpose. Finally, due to the high speed of the process air flow, liquid residues can also be sucked in and, together with dust and dirt, can be blown out of the suction device with the process air.

Die US-Patentschrift 3,820,310 offenbart ein Sauggerät gemäß dem Oberbegriff des Patentanspruchs 1.The U.S. Patent 3,820,310 discloses a suction device according to the preamble of patent claim 1.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein gattungsgemäßes Sauggerät weiterzuentwickeln, so dass die Gefahr von Beeinträchtigungen der Funktion durch Staub, Schmutz, Feuchtigkeit und Schaum so weit wie möglich reduziert wird, und das Sauggerät variabel für einen Nass-Trocken-Sauger oder für einen Trockensauger verwendbar ist.The object of the present invention is thus to develop a generic suction device, so that the risk of adverse effects on the function of dust, dirt, moisture and foam is reduced as much as possible, and the suction device variable for a wet-dry vacuum or for a dry vacuum is used.

Die Lösung besteht in einem Sauggerät mit den Merkmalen des Patentanspruchs 1. Erfindungsgemäß ist vorgesehen, dass ein den Schwimmer umgebender Filterkörper fest am Gehäuse angebracht ist, und dass ein den Filterkörper umschließender, im Wesentlichen topfförmiger Zykloneinsatz abnehmbar am Gehäuse angebracht ist.The solution consists in a suction device with the features of claim 1. The invention provides that a float surrounding the filter body is fixedly mounted on the housing, and that a filter body enclosing, substantially cup-shaped cyclone insert is removably attached to the housing.

Gemäß der vorliegenden Erfindung wird der Schwimmer von einem Filterkörper umgeben, der fest am Gehäuse angebracht ist. Der Filterkörper verhindert, dass im Anschluss an die Fliehkraftabscheidung ggf. mitgerissene Reste von Partikeln wie Schmutz oder Staub in den Strömungsweg des gereinigten Prozessluftstroms gelangen können. Daher können diese Verunreinigungen weder die Funktion des Schwimmers noch die Funktion des Motors beeinträchtigen. Diese Verunreinigungen werden ferner nicht mehr mit dem gereinigten Prozessluftstrom aus dem Gehäuse ausgeblasen. Der erfindungsgemäß den Filterkörper umschließende Zykloneinsatz ist abnehmbar am Gehäuse angebracht, so dass er leicht entfernt und wieder angebracht werden kann. Der Zykloneinsatz und der Filterkörper können somit leicht gereinigt werden. Ferner kann der Zykloneinsatz durch einen weiteren Filter für trockenen Staub und/oder Schmutz ersetzt werden, welcher ebenfalls abnehmbar am Gehäuse angebracht werden kann, und der den Filterkörper umschließt. Somit kann das Sauggerät auch für einen reinen Trockensauger verwendet werden.According to the present invention, the float is surrounded by a filter body fixedly attached to the housing. The filter body prevents entrained residues of particles such as dirt or dust from entering the flow path of the purified process air stream following centrifugal separation. Therefore, these impurities can affect neither the function of the float nor the function of the engine. These impurities are also no longer blown out of the housing with the purified process air stream. The inventively the filter body enclosing cyclone insert is removably attached to the housing, so that it can be easily removed and replaced. The cyclone insert and the filter body can thus be easily cleaned. Furthermore, the cyclone insert can be replaced by another filter for dry dust and / or dirt, which can also be removably attached to the housing, and which encloses the filter body. Thus, the suction device can also be used for a pure dry vacuum cleaner.

Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.Advantageous developments emerge from the subclaims.

Eine besonders bevorzugte Weiterbildung sieht vor, dass der obere freie Rand des Zykloneinsatzes vom Gehäuse beabstandet ist und eine Durchtrittsöffnung für den gereinigten Prozessluftstrom gebildet ist. Bei dieser Ausgestaltung tritt der gereinigte Prozessluftstrom entgegen der Bewegungsrichtung der abgeschiedenen Verunreinigungen in den vorgesehenen Strömungsweg ein. Damit wird zusätzlich verhindert, dass Feuchtigkeit, Schaum, Staub und/oder Schmutz in den Strömungsweg für den gereinigten Prozessluftstrom gelangen.A particularly preferred embodiment provides that the upper free edge of the cyclone insert is spaced from the housing and an opening for the purified process air flow is formed. In this embodiment, the purified process air stream enters the intended flow path counter to the direction of movement of the deposited impurities one. This additionally prevents moisture, foam, dust and / or dirt from entering the flow path for the purified process air stream.

Eine zusätzliche vorteilhafte Maßnahme besteht darin, dass der Bereich des oberen freien Randes des Zykloneinsatzes radial erweitert ausgebildet ist. Damit ist der Querschnitt der Durchtrittsöffnung für den gereinigten Prozessluftstrom vergrößert ausgebildet. Dies erleichtert den Zutritt des gereinigten Prozessluftstroms in den vorgesehenen Strömungsweg.An additional advantageous measure is that the area of the upper free edge of the cyclone insert is formed radially widened. Thus, the cross section of the passage opening for the purified process air flow is formed enlarged. This facilitates the access of the purified process air stream in the intended flow path.

Als weitere Maßnahme zur Optimierung der Steuerung des Prozessluftstroms kann in radialem Abstand vom oberen freien Rand des Zykloneinsatzes ein umlaufender Schutzschild am Gehäuse vorgesehen sein. Falls der Prozessluftstrom noch Verunreinigungen enthält, werden diese am Schutzschild abgeschieden. Die abgeschiedene Flüssigkeit bildet mit Schaum, Staub und/oder Schmutz durchsetzte Tropfen, die am Schutzschild abfließen. Diese Tropfen können vom Prozessluftstrom nicht mitgerissen werden, da sie hierfür zu schwer sind. Zur Optimierung dieser Wirkung kann der Schutzschild den freien oberen Rand des Zykloneinsatzes überragen.As a further measure to optimize the control of the process air flow, a circumferential protective shield may be provided on the housing at a radial distance from the upper free edge of the cyclone insert. If the process air stream still contains impurities, they are deposited on the shield. The separated liquid forms with foam, dust and / or dirt interspersed drops that drain on the shield. These drops can not be carried along by the process air flow as they are too heavy for this purpose. To optimize this effect, the shield can surmount the free upper edge of the cyclone insert.

Der Zykloneinsatz ist bspw. mittels eines Bajonettverschlusses abnehmbar am Gehäuse befestigt, so dass er auf besonders einfache Weise abgenommen und wieder montiert werden kann.The cyclone insert is, for example. By means of a bayonet lock removably attached to the housing so that it can be removed and re-assembled in a particularly simple manner.

Vorzugsweise ist der Filterkörper im Wesentlichen topfförmig ausgebildet, und umschließt den Schwimmer, so dass der Schwimmer geschützt ist, und ggf. mitgerissene Reste von Feuchtigkeit, Schaum, Schmutz und/oder Staub besonders zuverlässig zurückgehalten werden.Preferably, the filter body is substantially cup-shaped, and surrounds the float, so that the float is protected, and possibly entrained residues of moisture, foam, dirt and / or dust are retained particularly reliable.

Der Filterkörper kann bspw. als Filtergitter, Lochfilter, Papierfilter oder Vliesfilter ausgebildet sein. Die Ausgestaltung als Filtergitter oder Lochfilter aus Kunststoff ist bevorzugt, da ein solcher Filterkörper leicht von außen gereinigt werden kann.The filter body can be designed, for example, as a filter grid, perforated filter, paper filter or fleece filter. The design as a filter grid or hole filter made of plastic is preferred because such a filter body can be easily cleaned from the outside.

Vorzugsweise sind im Gehäuse separate Luftkammern und Austrittsöffnungen für den Prozessluftstrom einerseits sowie für einen, zur Kühlung eines Antriebsmotors dienenden, Kühlluftstrom andererseits, vorgesehen. Somit werden der Prozessluftstrom und der Kühlluftstrom in getrennten Luftkammern geführt, und aus getrennten Austrittsöffnungen ausgeblasen. Daher kann keine ggf. im Prozessluftstrom enthaltene Feuchtigkeit in den Bereich des Kühlluftstroms und damit in den Bereich des Motors eindringen, und diesen beschädigen.Preferably, separate air chambers and outlet openings for the process air flow on the one hand and for a, for cooling a drive motor serving, cooling air flow on the other hand, are provided in the housing. Thus, the process air flow and the cooling air flow in led separate air chambers, and blown out of separate outlet openings. Therefore, any moisture contained in the process air flow can not penetrate into the region of the cooling air flow and thus into the area of the engine, and damage it.

Das Sauggerät kann in an sich bekannter Weise ein als Sammelbehälter ausgebildetes Unterteil und ein Oberteil aufweisen, oder es kann in an sich bekannter Weise ein als Sammelbehälter ausgebildetes Unterteil und ein Oberteil, sowie ein zwischen Unterteil und Oberteil angeordnetes Mittelteil aufweisen. Dann können zweckmäßigerweise alle für die Funktion des erfindungsgemäßen Sauggeräts wesentlichen Bauteile am Oberteil und/oder am Mittelteil vorgesehen sein, so dass das Unterteil lediglich als Sammelbehälter dient, und auf einfache Weise entleert und gereinigt werden kann.The suction device may in known manner have a lower part designed as a collecting container and an upper part, or it may comprise, in a manner known per se, a lower part formed as a collecting container and an upper part, and a middle part arranged between lower part and upper part. Then, all components essential for the function of the suction device according to the invention can expediently be provided on the upper part and / or on the middle part, so that the lower part merely serves as a collecting container, and can be emptied and cleaned in a simple manner.

In the exemplary embodiment, the suction device 10 comprises a lower part 11 designed as a collecting container, a middle part 12 and a top part 13. In the exemplary embodiment, the upper part 13 and the middle part 12 are screwed together. The unit of upper part 13 and central part 12 is also referred to as a suction head. The middle part 12 is detachably connected to the lower part 11 by means of a lever closure 14. At the lower part 11 is an inlet nozzle 15 for a suction channel, for example. In the form of a known suction hose (not shown), provided.

Das Mittelteil 12 weist in an sich bekannter Weise einen Motor 16, im Ausführungsbeispiel in Form eines Bypass-Gebläsemotors, auf (nicht dargestellt). Der Bypass-Gebläsemotor 16 ist mit einem Axiallüfter 17 zum Erzeugen eines Kühlluftstroms K, und einem Radiallüfter 18 zum Erzeugen eines Prozessluftstroms P versehen. Beim Bypass-Gebläsemotor 16 sind Prozessluft und Kühlluft voneinander getrennt. Der Kühlluftstrom K durchströmt den Bypass-Gebläsemotor 16 und kühlt ihn. Der Prozessluftstrom P dient zum Ansaugen von Verunreinigungen wie Feuchtigkeit, Schmutz und/oder Staub. Der Axiallüfter 17 und der Radiallüfter 18 sind durch eine Dichtung 19 derart voneinander getrennt, dass sich Kühlluftstrom K und Prozessluftstrom P nicht miteinander vermischen können.The middle part 12 has a motor 16 in a manner known per se, in the exemplary embodiment in the form of a bypass fan motor (not shown). The bypass blower motor 16 is provided with an axial fan 17 for generating a cooling airflow K, and a centrifugal fan 18 for generating a process airflow P. In the bypass fan motor 16, process air and cooling air are separated from each other. The cooling air flow K flows through the bypass fan motor 16 and cools it. The process air flow P is used to suck in contaminants such as moisture, dirt and / or dust. The axial fan 17 and the radial fan 18 are separated by a seal 19 such that cooling air flow K and process air flow P can not mix with each other.

Der dem Unterteil 11 zugewandte Boden 21 des Mittelteils 12 weist einen Schwimmer 22 auf, der entlang der Mittelachse M des Sauggeräts 10 vertikal beweglich angeordnet ist. Der Schwimmer 22 dient in an sich bekannter Weise zur Füllstandsmessung des im Unterteil 11 angesammelten Wassers und/oder Schaums. Der Schwimmer 22 verschließt beim Erreichen einer vorgegebenen Füllstandshöhe im Unterteil 11 den Strömungsweg für den Prozessluftstrom P. Dadurch wird der Saugvorgang beendet. Der Schwimmer 22 ist besonders groß und leicht ausgestaltet, um auch auf die Füllstandshöhe von einem Wasser-Schaum-Gemisch ansprechen zu können.The lower part 11 facing bottom 21 of the central part 12 has a float 22 which is arranged vertically movable along the central axis M of the suction device 10. The float 22 is used in a conventional manner for level measurement of accumulated in the lower part 11 of water and / or foam. The float 22 closes upon reaching a predetermined level height in the lower part 11 of the flow path for the process air flow P. This completes the suction process. The float 22 is particularly large and slightly designed to be able to respond to the level of a water-foam mixture.

Der Schwimmer 22 ist von einem Filterkörper 23 umgeben, der im Ausführungsbeispiel aus Kunststoff besteht. Der Filterkörper 23 ist im Ausführungsbeispiel als im Wesentlichen topfförmiges Filtergitter mit einer zylindrischen Filterwand 24 und einem Filterboden 25 ausgebildet. Der Filterkörper 23 ist fest mit dem Boden 21 des Mittelteils 12 verbunden, und umschließt den Schwimmer 22. Der Filterkörper 23 dient dazu, im Prozessluftstrom P ggf. vorhandene Reste von Feuchtigkeit, Schaum, Schmutz und/oder Staub zurückzuhalten. Er schützt den Schwimmer 22 vor Verunreinigungen und vor mechanischen Beschädigungen bei der Montage eines Zykloneinsatzes (siehe unten).The float 22 is surrounded by a filter body 23, which consists in the embodiment of plastic. The filter body 23 is formed in the embodiment as a substantially cup-shaped filter grid with a cylindrical filter wall 24 and a filter bottom 25. The filter body 23 is fixedly connected to the bottom 21 of the middle part 12, and surrounds the float 22. The filter body 23 serves to retain in the process air flow P possibly existing residues of moisture, foam, dirt and / or dust. It protects the float 22 from contamination and mechanical damage when installing a cyclone insert (see below).

Der Filterkörper 23 ist von einem Zykloneinsatz 26 umschlossen, der im Ausführungsbeispiel aus einem Kunststoff besteht. Der Zykloneinsatz 26 ist im Ausführungsbeispiel im Wesentlichen topfförmig mit einer zylindrischen Zykloneinsatzwand 27 und einem Zykloneinsatzboden 28 ausgebildet. Der Zykloneinsatzboden 28 ist mit kleinen Öffnungen 29 sowie einem Handgriff 31 versehen. Die Öffnungen 29 dienen dazu, dass das gesammelte Wasser bzw. eine Wasser-Schaum-Mischung mit dem Schwimmer 22 in Kontakt treten kann, so dass dieser die Füllstandshöhe im Unterteil 11 messen kann, und ggf., wie oben beschrieben, den Strömungsweg für den Prozessluftstrom P blockieren kann. Ferner dienen die Öffnungen 29 dazu, dass beim Abnehmen des Oberteils 13 und Mittelteils 12 vom Unterteil 11 das bei hohem Füllstand des Unterteils 11 im Zykloneinsatz 26 stehende Wasser ablaufen kann. Der Zykloneinsatz 26 ist im Ausführungsbeispiel mittels eines Bajonettverschlusses 32 am Boden 21 des Mittelteils 12 abnehmbar befestigt. Der Handgriff 31 dient zur einfachen Handhabung des Zykloneinsatzes 26 bei der Montage bzw. Demontage. Der Filterkörper 23 schützt den Schwimmer 22 vor mechanischen Beschädigungen bei der Montage bzw. Demontage des Zykloneinsatzes 26.The filter body 23 is enclosed by a cyclone insert 26, which consists in the embodiment of a plastic. The cyclone insert 26 is formed in the embodiment substantially cup-shaped with a cylindrical cyclone insert wall 27 and a cyclone insert bottom 28. The cyclone insert bottom 28 is provided with small openings 29 and a handle 31. The openings 29 serve that the collected water or a water-foam mixture with the float 22 can come into contact, so that it can measure the level height in the lower part 11, and possibly, as described above, the flow path for the Process air flow P can block. Further, the openings 29 are used to ensure that when removing the upper part 13 and middle part 12 from the lower part 11, the standing at high level of the lower part 11 in the cyclone insert 26 water can drain. The cyclone insert 26 is removably attached in the embodiment by means of a bayonet lock 32 on the bottom 21 of the central part 12. The handle 31 is used for easy handling of the cyclone insert 26 during assembly or disassembly. The filter body 23 protects the float 22 against mechanical damage during assembly or disassembly of the cyclone insert 26.

Der obere freie Rand 33 des Zykloneinsatzes 26 ist im montierten Zustand vom Boden 21 des Mittelteils 12 beabstandet. Dadurch ist eine Durchtrittsöffnung 34 für den Prozessluftstrom P gebildet. Zur Vergrößerung der Durchtrittsöffnung 34 ist der obere freie Rand 33 des Zykloneinsatzes 26 radial erweitert ausgebildet, im Ausführungsbeispiel trichterförmig aufgeweitet.The upper free edge 33 of the cyclone insert 26 is spaced in the mounted state from the bottom 21 of the central part 12. As a result, a passage opening 34 for the process air flow P is formed. To increase the passage opening 34 of the upper free edge 33 of the cyclone insert 26 is formed radially widened, widened funnel-shaped in the embodiment.

In radialem Abstand vom oberen freien Rand 33 des Zykloneinsatzes 26 ist am Boden 21 des Mittelteils 12 ein umlaufender Schutzschild 35 befestigt. Der Schutzschild 35 besteht im Ausführungsbeispiel aus einem Kunststoff. Seine vertikale Höhe ist so bemessen, dass der Schutzschild 35 den oberen freien Rand 33 des Zykloneinsatzes 26 in Richtung des Unterteils 11 überragt. Der Schutzschild 35 dient zum Abscheiden von Feuchtigkeit, Schaum, Schmutz und/oder Staub aus dem Prozessluftstrom P.At a radial distance from the upper free edge 33 of the cyclone insert 26, a circumferential shield 35 is attached to the bottom 21 of the central part 12. The shield 35 is in the embodiment of a plastic. Its vertical height is dimensioned so that the protective shield 35 projects beyond the upper free edge 33 of the cyclone insert 26 in the direction of the lower part 11. The shield 35 serves to separate moisture, foam, dirt and / or dust from the process air stream P.

Der Zykloneinsatz 26 kann durch einen an sich bekannten Patronenfilter ersetzt werden, der ebenfalls, bspw. mit Hilfe eines Handgriffs, mittels eines korrespondierenden Bajonettverschlusses am Boden 21 des Mittelteils 12 befestigt werden kann (nicht dargestellt). Der Patronenfilter umschließt den Filterkörper 23 ebenso wie der Zykloneinsatz 26 vollständig. Der Patronenfilter kann ein Papier-, Vlies- oder Kunststofffilter sein. Mit dem Patronenfilter ist das Sauggerät 10 zur Verwendung als reiner Trockensauger ausgerüstet.The cyclone insert 26 can be replaced by a known per se cartridge filter, which can also, for example, by means of a handle, by means of a corresponding bayonet catch on the bottom 21 of the central part 12 can be attached (not shown). The cartridge filter encloses the filter body 23 as well as the cyclone insert 26 completely. The cartridge filter may be a paper, nonwoven or plastic filter. With the cartridge filter, the suction device 10 is equipped for use as a pure dry vacuum cleaner.

Wie es in den Figuren 2 und 3 anhand der Pfeile dargestellt ist, erzeugt das Sauggerät 10 im Betrieb in an sich bekannter Weise mittels des Radiallüfters 18 einen Prozessluftstrom P, ausgehend von einer Saugdüse (nicht dargestellt) über einen Saugkanal, bspw. ein Saugrohr und/oder einen Saugschlauch (nicht dargestellt), bis der Prozessluftstrom P durch den Einlassstutzen 15 in das Innere des Unterteils 11 eintritt.As it is in the Figures 2 and 3 shown in the arrows, the suction device 10 generates in operation in a conventional manner by means of the radial fan 18 a process air flow P, starting from a suction nozzle (not shown) via a suction channel, for example. A suction pipe and / or a suction hose (not shown) until the process air flow P enters through the inlet port 15 into the interior of the lower part 11.

Der Einlassstutzen 15 ist so gekrümmt, dass der Prozessluftstrom P im Wesentlichen tangential in das Unterteil 11 eintritt, und in eine kreisförmige Strömung von hoher Geschwindigkeit rund um den Zykloneinsatz 26 gezwungen wird. Aufgrund der dabei auftretenden Fliehkräfte werden die im Prozessluftstrom P vorhandenen Verunreinigungen, wie Flüssigkeit, Schaum, Schmutz und/oder Staub, nach außen in Richtung der Innenwand des Unterteils 11 geschleudert, so dass sie an der Innenwand auftreffen, dort abgeschieden werden, und in den unteren Bereich des als Sammelbehälter ausgebildeten Unterteils 11 absinken bzw. ablaufen.The inlet port 15 is curved so that the process air flow P enters the base 11 substantially tangentially and is forced into a circular flow of high velocity around the cyclone insert 26. Due to the centrifugal forces occurring in the process air flow P present impurities such as liquid, foam, dirt and / or dust are thrown outwards in the direction of the inner wall of the lower part 11 so that they impinge on the inner wall, are deposited there, and in the Lower or run down the lower portion of the formed as a collecting container lower part 11.

Der so gereinigte Prozessluftstrom P tritt durch die Durchtrittsöffnung 34 in den Zwischenraum 36 zwischen dem Zykloneinsatz 26 und dem Filterkörper 23 ein. Hierfür muss der Prozessluftstrom P den umlaufenden Schutzschild 35 unterlaufen, da dieser die Durchtrittsöffnung 34 verdeckt. Falls noch Reste von Verunreinigungen, wie Feuchtigkeit, Schaum, Schmutz und/oder Staub, im Prozessluftstrom P enthalten sind, prallen diese gegen den Schutzschild 35 und werden auf diese Weise vom Prozessluftstrom P abgetrennt. Die ggf. vom Prozessluftstrom P abgetrennte Flüssigkeit sammelt sich zu Tropfen, die vom Schutzschild 35 in Richtung des Unterteils 11 ablaufen. Diese Tropfen sind zu groß und schwer, um vom gereinigten Prozessluftstrom P in Richtung der Durchtrittsöffnung 34 mitgerissen zu werden.The thus purified process air flow P enters through the passage opening 34 into the intermediate space 36 between the cyclone insert 26 and the filter body 23. For this purpose, the process air flow P must circumvent the surrounding protective shield 35, since it covers the passage opening 34. If any residues of impurities, such as moisture, foam, dirt and / or dust, are contained in the process air flow P, they collide against the protective shield 35 and are separated in this way from the process air flow P. The optionally separated from the process air flow P liquid collects to drops that drain from the shield 35 in the direction of the lower part 11. These drops are too large and heavy to be carried along by the purified process air flow P in the direction of the passage opening 34.

Der Strömungsweg des Prozessluftstroms P durch die Durchtrittsöffnung 34 ist gegenüber einem möglichen Durchtritt durch die Öffnungen 29 im Boden 28 des Zykloneinsatzes 26 bevorzugt, da der Querschnitt der Öffnungen 29 viel kleiner ist als der Querschnitt der Durchtrittsöffnung 34.The flow path of the process air flow P through the passage opening 34 is preferred to a possible passage through the openings 29 in the bottom 28 of the cyclone insert 26, because the cross section of the openings 29 is much smaller than the cross section of the passage opening 34th

Der gereinigte Prozessluftstrom P tritt durch die Filterwand 24 des Filterkörpers 23 in dessen Innenraum ein. Der Filterkörper 23 dient als weitere Barriere für Verunreinigungen, die trotz der bisher beschriebenen Maßnahmen noch im Prozessluftstrom P enthalten sein könnten. Die Verunreinigungen scheiden sich an der Filterwand 24 des Filterkörpers 23 ab. Der Prozessluftstrom P umströmt den Schwimmer 22, und tritt in eine umlaufende separate Luftkammer 37 im Inneren des Mittelteils 12 ein. Die Luftkammer 37 mündet in eine im Mittelteil 12 vorgesehene separate Austrittsöffnung 38, durch welche der gereinigte Prozessluftstrom P aus dem Sauggerät 10 austritt. Mit dem Prozessluftstrom P treten keine Verunreinigungen, wie Feuchtigkeit, Staub und/oder Schmutz, aus der Austrittsöffnung 38 aus.The purified process air flow P enters through the filter wall 24 of the filter body 23 in the interior thereof. The filter body 23 serves as a further barrier for impurities that could still be contained in the process air flow P despite the measures described so far. The impurities are deposited on the filter wall 24 of the filter body 23. The process air flow P flows around the float 22, and enters into a circulating separate air chamber 37 in the interior of the central part 12. The air chamber 37 opens into a provided in the middle part 12 separate outlet opening 38, through which the purified process air flow P exits the suction device 10. With the process air flow P occur no impurities such as moisture, dust and / or dirt from the outlet opening 38.

Der vom Bypass-Gebläsemotor 16 mittels des Axiallüfters 17 erzeugte Kühlluftstrom K tritt nach dem Durchströmen des Motors 16 in eine weitere, umlaufende separate Luftkammer 39 im Inneren des Mittelteils 12 ein. Die Luftkammer 39 mündet in eine im Mittelteil 12 vorgesehene separate Austrittsöffnung 41, durch welche der Kühlluftstrom aus dem Sauggerät 10 austritt.The cooling air flow K generated by the bypass fan motor 16 by means of the axial fan 17 occurs after flowing through the motor 16 in a further, circulating separate air chamber 39 in the interior of the central part 12 a. The air chamber 39 opens into a provided in the middle part 12 separate outlet opening 41, through which the cooling air flow exiting the suction device 10.

Durch diese Führung von Prozessluftstrom P und Kühlluftstrom K wird verhindert, dass sich die beiden Luftströme P, R mischen, und bspw. Feuchtigkeit in den Bypass-Gebläsemotor 16 eindringen und diesen beschädigen kann.This guidance of process air flow P and cooling air flow K prevents the two air streams P, R mixing and, for example, moisture from penetrating into the bypass fan motor 16 and damaging it.
