Description

Die Erfindung betrifft einen Luftstromregler mit den Merkmalen des Oberbegriffes von Patentanspruch 1. Derartige Luftstromregler sind aus der DE 41 02 810 A1 bekannt.The invention relates to an air flow regulator with the features of the preamble of claim 1. Such air flow regulator are from the DE 41 02 810 A1 known.

Luftstromregler zum Regulieren des durch eine Saugdüse eines Staubsaugers hindurchströmenden Saugluftstromes mit einem den Saugluftstrom aufnehmenden Saugkanal, dem über mindestens eine Falschluftöffnung Falschluft zuführbar ist, wobei die Falschluftöffnung mittels eines Schließteiles wahlweise freigebbar oder verschließbar ist, kommen bei Staubsaugern zum Einsatz. Mit ihrer Hilfe kann der durch eine Saugdüse des Staubsaugers hindurchströmende Saugluftstrom reguliert werden. Soll beispielsweise ein hochfloriger Teppich abgesaugt werden, so ist es vorteilhaft, wenn ein möglichst starker Saugluftstrom durch die Saugdüse hindurchtritt, um dadurch eine möglichst intensive Reinigung des Teppichs zu erzielen. Ein intensiver Saugluftstrom ist allerdings nicht in allen Fällen wünschenswert, beispielsweise beim Absaugen von Vorhängen oder auch von empfindlichen Polstern ist es günstig, wenn der durch die Saugdüse hindurchströmende Saugluftstrom eine geringere Intensität aufweist. Hierzu kann der Luftstromregler mit einem Saugkanal zwischen die Saugdüse und eine Saugleitung des Staubsaugers geschaltet werden, und mittels des Luftstromreglers kann dem Saugkanal unter Umgehung der Saugdüse Falschluft zugeführt werden, so dass der durch die Saugdüse hindurchströmende Saugluftstrom abgeschwächt wird. Der Saugkanal umfasst hierzu mindestens eine Falschluftöffnung, die mittels eines Schließteiles vom Benutzer wahlweise freigegeben oder verschlossen werden kann. Ein derartiger Luftstromregler ist aus der US-A-2 176 139 bekannt.Air flow regulator for regulating the suction air flow passing through a suction nozzle of a vacuum cleaner with a suction duct receiving the suction air stream, to which secondary air can be supplied via at least one false air opening, the false air opening being selectively releasable or closable by means of a closing member, are used in vacuum cleaners. With their help, the suction air flow passing through a suction nozzle of the vacuum cleaner can be regulated. For example, if a high-pile carpet to be sucked, it is advantageous if the strongest possible suction air flow passes through the suction nozzle, thereby achieving the most intensive cleaning of the carpet. However, an intensive suction air flow is not desirable in all cases, for example, when sucking curtains or sensitive padding, it is advantageous if the suction air flowing through the suction nozzle has a lower intensity. For this purpose, the air flow regulator can be connected with a suction channel between the suction nozzle and a suction line of the vacuum cleaner, and by means of the air flow regulator can be supplied to the suction channel bypassing the suction false air, so that the suction air flowing through the suction nozzle stream is attenuated. For this purpose, the suction channel comprises at least one false air opening, which can be selectively released or closed by the user by means of a closing part. Such a flow regulator is out of US-A-2,176,139 known.

Die Zuführung von Falschluft über die Falschluftöffnung ist in vielen Fällen mit einer störenden Geräuschentwicklung verbunden.The supply of false air through the false air opening is in many cases associated with a disturbing noise.

Aufgabe der vorliegenden Erfindung ist es, einen Luftstromregler der eingangs genannten Art derart weiterzubilden, dass die Falschluft dem Saugkanal geräuschärmer zuführbar ist.Object of the present invention is to develop an air flow regulator of the type mentioned in such a way that the false air is quieter fed to the suction port.

Diese Aufgabe wird durch einen Luftstromregler mit den Merkmalen von Patentanspruch 1 gelöst.This object is achieved by an air flow regulator with the features of claim 1.

In die Erfindung fließt der Gedanke mit ein, dass eine Geräuschentwicklung bei der Zuführung von Falschluft reduziert werden kann, indem die Zuführung von Falschluft ohne Umlenkungen erfolgt. Hierzu ist die Falschluft parallel zur Strömungsrichtung der Saugluft zuführbar. Dadurch kann die Geräuschentwicklung ganz erheblich vermindert werden. Erfindungsgemäß weist das Schließteil zumindest einen Falschluftkanal auf, der wahlweise fluchtend oder versetzt zur Falschluftöffnung positionierbar ist, wobei Falschluft parallel zur Strömungsrichtung der Saugluft über den Falschluftkanal der Falschluftöffnung zuführbar ist. Das Schließteil ist relativ zu der mindestens einen Falschluftöffnung bewegbar gehalten, so dass je nach Stellung des Schließteiles die Falschluftöffnung freigegeben oder aber vom Schließteil verschlossen ist. Die Zuführung von Falschluft zum Saugkanal erfolgt über das Schließteil, das hierzu einen Falschluftkanal aufweist, der fluchtend zur Falschluftöffnung ausgerichtet werden kann und über den die Falschluft parallel zur Strömungsrichtung der Saugluft der.Falschluftöffnung zuführbar ist. Die Zuführung der Falschluft erfolgt somit ohne Umlenkungen, die eine Geräuschentwicklung zur Folge hätten. Der Falschluftkanal kann beispielsweise als Durchbrechung oder als Nut ausgestaltet sein.In the invention, the idea flows in that a noise in the supply of false air can be reduced by the supply of false air occurs without deflections. For this purpose, the false air can be fed parallel to the flow direction of the suction air. As a result, the noise can be significantly reduced. According to the invention, the closing part has at least one false air duct, which can be positioned either in an aligned manner or displaced to the false air opening, wherein false air can be supplied to the false air opening in parallel to the flow direction of the suction air via the false air duct. The closing part is held movable relative to the at least one false air opening, so that depending on the position of the closing part, the false air opening is released or closed by the closing part. The supply of false air to the suction channel via the closing part, which for this purpose has a false air duct, which can be aligned with the false air opening and over which the false air is fed parallel to the flow direction of the suction air der.Falschluftöffnung. The supply of false air thus takes place without deflections that would cause a noise. The false air channel can be configured for example as an opening or as a groove.

Vorzugsweise weist der Saugkanal einen Erweiterungsabschnitt auf, in dem sich der Strömungsquerschnitt des Saugkanals erweitert, wobei die mindestens eine Falschluftöffnung im Erweiterungsabschnitt angeordnet ist. Hierbei ist es von besonderem Vorteil, wenn der Erweiterungsabschnitt ringförmig ausgestaltet ist, denn dies gibt die Möglichkeit, mehrere Falschluftöffnungen über den Erweiterungsabschnitt vorzugsweise gleichförmig verteilt anzuordnen.The suction channel preferably has an extension section, in which the flow cross section of the suction channel widens, wherein the at least one false air opening is arranged in the extension section. In this case, it is of particular advantage if the extension section is of annular design, because this gives the possibility of arranging a plurality of false air openings preferably uniformly distributed over the extension section.

Bei einer konstruktiv besonders einfachen Ausgestaltung weist der Erweiterungsabschnitt eine radial nach außen gerichtete Stufe auf.In a structurally particularly simple embodiment, the extension section has a radially outwardly directed step.

Von Vorteil ist es, wenn in der Stufe zumindest zwei, über den Umfang des Strömungskanals gleichmäßig verteilte Falschluftöffnungen angeordnet sind. Als günstig hat es sich erwiesen, wenn zwei Falschluftöffnungen im Bereich der Stufe einander diametral gegenüberliegen.It is advantageous if at least two, evenly distributed over the circumference of the flow channel false air openings are arranged in the stage. It has proved to be favorable if two false air openings in the region of the step are diametrically opposed to one another.

Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Luftstromreglers umfasst dieser ein Rohrstück, das den Saugkanal ausbildet, und das Schließteil ist als das Rohrstück in Höhe der mindestens einen Falschluftöffnung umgreifende Hülse ausgebildet, die relativ zum Rohrstück verdrehbar ist, wobei die Falschluft über mindestens einen sich parallel zur Strömungsrichtung der Saugluft erstreckenden Durchgang der Falschluftöffnung zuführbar ist und die Falschluftöffnung mittels der Hülse wahlweise freigebbar oder verschließbar ist. Bei einer derartigen Ausgestaltung erfolgt die Zuführung von Falschluft über einen Durchgang, der beispielsweise zwischen der Hülse und dem Rohrstück angeordnet sein kann oder auch in die Hülse eingeformt sein kann.
Durch Drehen der Hülse kann die Falschluftöffnung vom Benutzer wahlweise verschlossen oder freigegeben werden. Hierbei kann je nach Drehstellung der Hülse die Falschluftöffnung mehr oder weniger verschlossen werden, das heißt die Menge der zuführbaren Falschluft ist kontinuierlich regulierbar.In a preferred embodiment of the air flow regulator according to the invention this comprises a piece of pipe which forms the suction channel, and the closing part is formed as the pipe piece at the level of at least one false air opening embracing sleeve which is rotatable relative to the pipe section, wherein the false air over at least one parallel to Flow direction of the suction air extending passage of the false air opening can be supplied and the false air opening by means of the sleeve is selectively releasable or closable. In such an embodiment, the supply of false air via a passage which may be arranged for example between the sleeve and the pipe piece or may also be formed in the sleeve.
By rotating the sleeve, the false air opening can optionally be closed or released by the user. Here, depending on the rotational position of the sleeve, the false air opening can be more or less closed, that is, the amount of supplied false air is continuously regulated.

Zur Ausbildung eines Durchganges zwischen der Hülse und dem Rohrstück kann vorgesehen sein, dass der Innendurchmesser der Hülse mit Ausnahme zumindest eines Überdeckungsabschnittes größer gewählt ist als der Außendurchmesser des Rohrstückes. In einer ersten Drehstellung der Hülse kann der mindestens eine Überdeckungsabschnitt versetzt zur Falschluftöffnung angeordnet sein, so dass über den Durchgang zwischen der Hülse und dem Rohrstück Falschluft der Falschluftöffnung zugeführt werden kann. In einer zweiten Drehstellung kann der Überdeckungsabschnitt der Hülse die Falschluftöffnung überdecken, so dass die Zuführung von Falschluft unterbunden ist.To form a passage between the sleeve and the pipe piece can be provided that the inner diameter of the sleeve with the exception of at least one overlap portion is selected to be greater than the outer diameter of the pipe section. In a first rotational position of the sleeve, the at least one overlapping section can be arranged offset to the secondary air opening, so that over the passage between the sleeve and the pipe section false air of the false air opening can be supplied. In a second rotational position of the cover portion of the sleeve can cover the false air opening, so that the supply of false air is prevented.

Es kann auch vorgesehen sein, dass der Durchgang als in die Hülse eingeformte Ausnehmung ausgestaltet ist, die einen wahlweise fluchtend oder versetzt zu einer Falschluftöffnung ausrichtbaren Falschluftkanal ausbildet, über den die Falschluft parallel zur Strömungsrichtung der Saugluft der Falschluftöffnung zuführbar ist. Bei einer derartigen Ausgestaltung kann die Hülse in Umfangsrichtung zumindest in Teilbereichen an der Außenseite des Rohrstükkes anliegen. Durch Drehen der Hülse kann diese derart positioniert werden, dass die mindestens eine Ausnehmung fluchtend zu einer Falschluftöffnung des Rohrstückes ausgerichtet ist, so dass Falschluft parallel zur Strömungsrichtung der Saugluft dem Saugkanal zugeführt werden kann.It can also be provided that the passage is designed as a recess formed in the sleeve, which forms an optionally aligned or offset to a false air opening alignable false air duct, via which the false air can be fed parallel to the flow direction of the suction air of the false air opening. In such an embodiment, the sleeve may rest in the circumferential direction, at least in some areas on the outside of the Rohrstükkes. By rotating the sleeve, it can be positioned in such a way the at least one cutout is aligned in alignment with a false air opening of the pipe section, so that secondary air can be supplied to the suction channel parallel to the flow direction of the suction air.

Eine besonders einfache Handhabung des Luftstromreglers kann dadurch erzielt werden, dass die Hülse axial unverschieblich am Rohrstück gehalten ist. Zum Freigeben der Falschluftöffnung muss bei einer derartigen Ausgestaltung die Hülse vom Benutzer lediglich relativ zum Rohrstück verdreht werden, es ist jedoch keine zusätzliche axiale Bewegung der Hülse erforderlich.A particularly simple handling of the air flow regulator can be achieved in that the sleeve is held axially immovably on the pipe section. To release the false air opening the sleeve must be rotated by the user only relative to the pipe section in such an embodiment, but there is no additional axial movement of the sleeve required.

Zur Vereinfachung der Montage ist bei einer vorteilhaften Ausführungsform vorgesehen, dass die Hülse mit dem Rohrstück verrastbar ist. So kann beispielsweise vorgesehen sein, dass das Rohrstück einen Rastvorsprung umfasst, der von einer Rastnase der Hülse hintergreifbar ist.To simplify the assembly is provided in an advantageous embodiment that the sleeve can be locked with the pipe section. For example, it may be provided that the tube piece comprises a latching projection, which can be engaged behind by a latching nose of the sleeve.

Besonders vorteilhaft ist es, wenn das Rohrstück einen ersten Rohrabschnitt aufweist, der sich über eine Stufe in einen zweiten Rohrabschnitt erweitert, wobei im Abstand zur Stufe am ersten Rohrabschnitt ein Rastvorsprung angeordnet ist und die Hülse mittels eines innenseitigen Bundes axial unbeweglich zwischen der Stufe und dem Rastvorsprung gehalten ist.It is particularly advantageous if the pipe section has a first pipe section, which widens via a step into a second pipe section, wherein a locking projection is arranged at a distance from the step on the first pipe section and the sleeve by means of an inside Federal axially immovable between the step and the Latching projection is held.

Von besonderem Vorteil ist es, wenn das Rohrstück einen Handgriff zur Handhabung einer an diesem angeschlossenen Saugdüse ausbildet. Die Saugdüse kann bei einer derartigen Ausgestaltung mittels des Rohrstückes an einer zu reinigenden Fläche entlang bewegt werden.It is particularly advantageous if the tube piece forms a handle for handling a suction nozzle connected thereto. The suction nozzle can be moved in such a configuration by means of the pipe section along a surface to be cleaned.

Vorzugsweise ist das Rohrstück gekrümmt, denn dadurch kann das Rohrstück vom Benutzer in ergonomisch günstiger Weise ergriffen werden.Preferably, the pipe section is curved, because thereby the pipe section can be taken by the user in an ergonomically favorable manner.

In Figur 1 ist schematisch ein Staubsauger 10 dargestellt mit einem Sauggerät 11, an das eine Saugleitung in Form eines flexiblen Saugschlauches 12 angeschlossen ist. Der Saugschlauch 12 trägt an seinem freien Ende einen erfindungsgemäßen Luftstromregler 14, der ein Rohrstück 16 aufweist, auf den ein Schließteil in Form einer das Rohrstück 16 in Umfangsrichtung umgebenden Hülse 18 aufgesteckt ist. In den Figuren 1 und 2 ist die Hülse 18 nach Art einer Explosionszeichnung im Abstand zum Rohrstück 16 angeordnet, wohingegen in den Figuren 3 bis 6 der Luftstromregler 14 im montierten Zustand dargestellt ist.In FIG. 1 schematically a vacuum cleaner 10 is shown with a suction device 11, to which a suction line in the form of a flexible suction hose 12 is connected. The suction hose 12 carries at its free end an air flow regulator 14 according to the invention, which has a pipe section 16, onto which a closing part in the form of a sleeve 18 surrounding the pipe section 16 in the circumferential direction is attached. In the FIGS. 1 and 2 the sleeve 18 is arranged in the manner of an exploded view at a distance from the pipe section 16, whereas in the FIGS. 3 to 6 the air flow regulator 14 is shown in the assembled state.

Das Rohrstück 16 umfasst einen vorderen Rohrabschnitt 20, an den eine in der Zeichnung nicht dargestellte, an sich bekannte Saugdüse angeschlossen werden kann, sowie einen hinteren Rohrabschnitt 22, der an seinem hinteren Ende ein Anschlussteil 23 aufweist zur Herstellung einer lösbaren Verbindung mit dem Saugschlauch 12.The pipe section 16 comprises a front pipe section 20, to which a suction nozzle, not shown in the drawing, can be connected, and a rear pipe section 22, which has a connection part 23 at its rear end for producing a detachable connection with the suction hose 12 ,

Der hintere Rohrabschnitt 22 ist gekrümmt und bildet einen Handgriff 24 aus, an dem der Benutzer den Luftstromregler 14 ergreifen kann.The rear tube section 22 is curved and forms a handle 24 from which the user can grasp the air flow regulator 14.

Der vordere Rohrabschnitt 20 verjüngt sich in Richtung auf dessen freies Ende 26 und kann in einen Rohrstutzen einer Saugdüse des Staubsaugers 10 eingesetzt werden.The front pipe section 20 tapers in the direction of its free end 26 and can be inserted into a pipe socket of a suction nozzle of the vacuum cleaner 10.

Das Rohrstück 16 definiert einen Saugkanal 30 und weist im Bereich zwischen dem vorderen Rohrabschnitt 20 und dem hinteren Rohrabschnitt 22 einen Erweiterungsabschnitt 32 auf, in dem sich der Strömungsquerschnitt des Saugkanals 30 über eine radial nach außen gerichtete Stufe 34 erweitert. In die Stufe 34 sind einander diametral gegenüberliegend zwei Falschluftöffnungen 36, 37 eingeformt. In axialem Abstand zur Stufe 34 ist außenseitig an den vorderen Rohrabschnitt 20 ein radial nach außen gerichteter Rastvorsprung 39 angeformt, der den vorderen Rohrabschnitt 20 in Umfangsrichtung vollständig umgibt.The pipe section 16 defines a suction channel 30 and has an extension section 32 in the area between the front pipe section 20 and the rear pipe section 22, in which the flow cross section of the suction channel 30 widens via a radially outwardly directed step 34. In the Step 34 are diametrically opposite two false air openings 36, 37 formed. At an axial distance from the step 34, a radially outwardly directed locking projection 39 is integrally formed on the outside of the front pipe section 20, which completely surrounds the front pipe section 20 in the circumferential direction.

Die Hülse 18 umgreift in Höhe der Stufe 34 das Rohrstück 16 und weist innenseitig einen Bund 41 auf, der einerseits am Rastvorsprung 39 und andererseits an der Stufe 34 anliegt und daher die Hülse 18 in axialer Richtung festlegt.The sleeve 18 engages around the level of the step 34, the pipe section 16 and has on the inside a collar 41, which rests on the one hand on the locking projection 39 and on the other hand on the step 34 and therefore determines the sleeve 18 in the axial direction.

Innenseitig sind in die Hülse einander diametral gegenüberliegend zwei Ausnehmungen 43, 44 eingeformt, die jeweils einen Falschluftkanal ausbilden, indem sie einen Durchgang 46 bzw. 47 zwischen der Hülse 18 und der Außenseite des vorderen Rohrabschnittes 20 definieren.On the inside diametrically opposite two recesses 43, 44 are formed in the sleeve, each forming a false air passage by defining a passage 46 and 47 between the sleeve 18 and the outside of the front pipe section 20.

Die Hülse 18 ist um die Längsachse 49 des vorderen Rohrabschnitts 20 verdrehbar am Rohrstück 16 gehalten und kann zwischen einer ersten, in den Figuren 3 und 5 dargestellten Drehstellung und einer zweiten, in den Figuren 4 und 6 dargestellten Drehstellung kontinuierlich hin und her verdreht werden. In der ersten Drehstellung überdeckt der Bund 41 die Falschluftöffnungen 36 und 37, so dass über diese keine Falschluft von außen in den Saugkanal 30 eintreten kann. In der zweiten Drehstellung sind die Ausnehmungen 43 und 44 fluchtend zur Falschluftöffnung 36 bzw. 37 ausgerichtet, und folglich kann Falschluft parallel zur Strömungsrichtung 51 der den Saugkanal 30 durchströmenden Saugluft dem Saugkanal 30 zugeführt werden. Die Strömungsrichtung der Falschluft ist in Figur 4 durch die Pfeile 53 symbolisiert.The sleeve 18 is held about the longitudinal axis 49 of the front pipe section 20 rotatable on the pipe section 16 and can between a first, in the Figures 3 and 5 shown rotational position and a second, in the FIGS. 4 and 6 shown rotational position are continuously rotated back and forth. In the first rotational position, the collar 41 covers the false air openings 36 and 37, so that no false air from the outside can enter into the suction channel 30 via this. In the second rotational position, the recesses 43 and 44 are aligned with the false air opening 36 or 37, and consequently, false air can be supplied to the suction channel 30 parallel to the flow direction 51 of the suction channel 30 flowing through the suction air. The flow direction of the false air is in FIG. 4 symbolized by the arrows 53.

Die Falschluft durchströmt somit sowohl die Ausnehmungen 43 und 44 der Hülse 18 als auch die Falschluftöffnungen 36 und 37 des Rohrstückes 16 parallel zur Strömungsrichtung 51 der Saugluft. Dies hat zur Folge, dass die Zuführung von Falschluft in den Saugkanal 30 ohne Umlenkungen erfolgen kann, und dies wiederum stellt sicher, dass die Zuführung von Falschluft ohne starke Geräuschentwicklung erfolgt.The false air thus flows through both the recesses 43 and 44 of the sleeve 18 and the false air openings 36 and 37 of the pipe section 16 parallel to the flow direction 51 of the suction air. This has the consequence that the supply of false air into the suction channel 30 can be done without deflections, and this in turn ensures that the supply of false air occurs without strong noise.
