Description

Die Erfindung betrifft ein an einen mit einem Staubsauger verbundenes Saugrohr anschließbares Saugmundstück, das mindestens einen von der Saugöffnung ausgehenden und sich quer im Boden des Saugmundstückes erstreckenden Saugkanal aufweist.The invention relates to a suction mouthpiece which can be connected to a suction pipe connected to a vacuum cleaner and which has at least one suction channel starting from the suction opening and extending transversely in the bottom of the suction mouthpiece.

Ein solches Saugmundstück ist durch die DE-B2-28 55 070 bekannt. Zur Verbesserung der Reinigungswirkung sind bei diesem Mundstück die den Saugkanal begrenzenden Kanten in der Höhe gegeneinander versetzt und insgesamt tiefer als die Tragfläche des Mundstückes angeordnet. Durch eine solche Gestaltung des Mundstückes läßt sich eine gute "Reinigungswirkung beim Absaugen von losem und körnigem Schmutz erzielen. Zwar sind beim Saugen einer Boden- oder Teppichfläche größtenteils nur lose Schmutzpartikel zu entfernen, jedoch muß das Saugmundstück zur Erzielung einer umfassenden Reinigungswirkung auch noch Zusatzfunktionen erfüllen, wie beispielsweise Randsaugen an den Schmalseiten des Mundstückes oder an seiner Frontseite, ferner Fäden oder Fasern saugen sowie Intensivsaugen über Ritzen oder besonders stark verschmutzte Stellen.Such a suction mouthpiece is known from DE-B2-28 55 070. In order to improve the cleaning effect, the edges of the suction channel delimiting the suction channel are offset from one another in height and are arranged overall lower than the wing of the mouthpiece. With such a design of the mouthpiece, a good " cleaning effect can be achieved when vacuuming loose and granular dirt. While vacuuming a floor or carpet surface mostly only loose dirt particles have to be removed, the suction mouthpiece must also perform additional functions in order to achieve a comprehensive cleaning effect , such as edge suction on the narrow sides of the mouthpiece or on its front side, also suck threads or fibers and intensive suction over cracks or particularly heavily soiled areas.

Die optimale Erfüllung sowohl der Hauptfunktion als auch der einzelnen Zusatzfunktionen stellt an die konstruktive Gestaltung des Saugmundstückes Anforderungen, die teilweise einander widersprechen. Beispielsweise wird dadurch, daß ein Fadenheber ständig in der Arbeitsstellung ist, das Staubaufnahmevermögen von einem textilen Bodenbelag verschlechtert oder es sinkt die Saugwirkung in der Mitte des Saugmundstückes ab, wenn der Luftstrom zur Erzielung einer optimalen Reinigungswirkung beim Randsaugen an einer oder beiden Seiten des Saugmundstückes konzentriert wird. Die gleichzeitige optimale Erfüllung aller Funktionen ist deshalb bisher ungelöst.The optimal fulfillment of both the main function and the individual additional functions places demands on the structural design of the suction mouthpiece, some of which contradict each other. For example, the fact that a thread lifter is always in the working position worsens the dust absorption capacity of a textile floor covering or the suction effect in the middle of the suction mouthpiece decreases when the air flow to achieve a optimal cleaning effect during edge suction is concentrated on one or both sides of the suction nozzle. The simultaneous optimal fulfillment of all functions has therefore not yet been resolved.

Der Erfindung liegt die Aufgabe zugrunde, ein Saugmundstück für einen Staubsauger so auszugestalten, daß sowohl beim üblichen Saugen als auch bei speziellen Reinigungsvorgängen (Randsaugen, Fadensaugen, Intensivsaugen) eine möglichst optimale Reinigungswirkung erzielt wird.The invention has for its object to design a suction mouthpiece for a vacuum cleaner so that the best possible cleaning effect is achieved both during normal suction and during special cleaning processes (edge suction, thread suction, intensive suction).

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß im Saugkanal mindestens ein die Saugfunktion änderndes Zusatzorgan angeordnet ist, das mit einem vom Führungshandgriff aus zu steuernden Antrieb gekoppelt ist. Beim Saugen kann somit je nach Bedarf das Zusatzorgan vom Führungshandgriff aus betätigt werden und das Saugmundstück dem jeweiligen Bedarfsfall angepaßt werden.The object is achieved according to the invention in that at least one additional element which changes the suction function is arranged in the suction channel and is coupled to a drive to be controlled from the guide handle. When vacuuming, the additional element can thus be actuated from the guide handle as required and the suction mouthpiece can be adapted to the respective need.

Besonders vorteilhaft ist es, daß zur Betätigung des Zusatzorganes ein pneumatischer Antrieb vorgesehen ist. Eine konstruktiv einfache Ausführungsform eines pneumatischen Antriebs und seiner Steuerung ergibt sich dadurch, daß im Saugkanal ein durch eine Membran oder einen-Faltenbalg gegenüber dem im Saugkanal herrschenden Unterdruck abgeschlossener Druckraum vorgesehen ist und das Zusatzorgan mit der Membran bzw. dem Faltenbalg verbunden ist, daß ferner ein im Druckraum mündender und sich bis zum Führungshandgriff erstreckender Leitungskanal vorgesehen ist, der über ein am Führungshandgriff angeordnetes Steuerelement wahlweise mit der Außenluft oder dem Innenraum des Saugrohres verbindbar ist. Zur Erhöhung der Funktionssicherheit ist es weiterhin vorteilhaft, daß eine mit der Membran oder dem Faltenbalg gekoppelte Zugfeder vorgesehen ist, deren Kraft der Unterdruckkraft im Saugkanal entgegengerichtet ist.It is particularly advantageous that a pneumatic drive is provided for actuating the additional element. A structurally simple embodiment of a pneumatic drive and its control results from the fact that in the suction channel a pressure chamber is provided, which is closed off by a membrane or a bellows with respect to the negative pressure prevailing in the suction channel, and the additional element is connected to the membrane or the bellows, furthermore, that a line duct opening into the pressure chamber and extending as far as the guide handle is provided, which can optionally be connected to the outside air or the interior of the intake manifold via a control element arranged on the guide handle. To increase the functional reliability, it is furthermore advantageous that a tension spring coupled to the membrane or the bellows is provided, the force of which is directed counter to the negative pressure force in the suction channel.

Entsprechend einer weiteren Ausgestaltung der Erfindung ist zur Verstellung des Zusatzorganes ein elektromagnetischer Antrieb vorgesehen und am Führungshandgriff ein über Steuerleitungen mit der Spule der Elektromagneten verbundener Steuerschalter angeordnet.According to a further embodiment of the invention, an electromagnetic drive is provided for adjusting the additional element and a control switch connected to the coil of the electromagnet via control lines is arranged on the guide handle.

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

  • Fig. 1 ein auf ein mit einem Staubsauger verbundenes Saugrohr aufgestecktes Saugmundstück,
  • Fig. 2 ein Saugmundstück und einen Führungshandgriff im Detailschnitt.
The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows
  • 1 shows a suction mouthpiece plugged onto a suction pipe connected to a vacuum cleaner,
  • Fig. 2 shows a suction nozzle and a guide handle in a detail section.

In Fig. 1 ist mit 1 ein Saugrohr bezeichnet, auf dessen oberes Ende ein Führungshandgriff 2 aufgesteckt ist, an dem ein zu einem Staubsauger führender Saugschlauch 3 angeschlossen ist. Auf das untere Ende des Saugrohres 1 ist ein Saugmundstück 4 aufgesteckt. Das Saugmundstück 4 weist einen sich quer in dessen Boden erstreckenden Saugkanal 5 auf. In der Mitte des Saugmundstückes ist bekannterweise eine in den Saugkanal 5 mündende Saugöffnung vorgesehen, die über einen am Gehäuse des Saugmundstückes 4 angeformten Anschlußstutzen 6 mit dem Saugrohr 1 in Verbindung steht. Wie in Fig. 1 schematisch angedeutet, ist in dem Saugkanal 5 ein Faltenbalg 7 angeordnet, an dem beispielsweise ein Fadenheber 8 befestigt ist. Der Faltenbalg 7 bildet zusammen mit dem Fadenheber 8-einen Druckraum 9. Von dem Druckraum 9 führt ein Leitungskanal 10 zu einem an dem Führungshandgriff .2 angeordneten Steuerelement 11.In Fig. 1, 1 denotes a suction pipe, on the upper end of which a guide handle 2 is attached, to which a suction hose 3 leading to a vacuum cleaner is connected. A suction mouthpiece 4 is slipped onto the lower end of the suction pipe 1. The suction mouthpiece 4 has a suction channel 5 extending transversely in the bottom thereof. As is known, a suction opening opening into the suction channel 5 is provided in the middle of the suction mouthpiece and is connected to the suction pipe 1 via a connecting piece 6 formed on the housing of the suction mouthpiece 4. As indicated schematically in FIG. 1, a bellows 7 is arranged in the suction channel 5, to which a thread lifter 8 is attached, for example. The bellows 7 forms a pressure chamber 9 together with the thread lifter 8. A pressure duct 9 leads from the pressure chamber 9 to a control element 11 arranged on the guide handle 2.

Wie aus der Detaildarstellung in Fig. 2 zu erkennen, ist in dem Druckraum 9 ferner eine Zugfeder 12 angebracht, welche den mit dem Faltenbalg 7 verbundenen Fadenheber 8 entgegen den im Saugkanal 5 herrschenden Unterdruck nach oben zieht.As can be seen from the detailed illustration in FIG. 2, a tension spring 12 is also mounted in the pressure chamber 9, which pulls the thread lifter 8 connected to the bellows 7 upwards against the negative pressure prevailing in the suction channel 5.

Der Leitungskanal 10 ist auf einen an dem Druckraum 9 angeformten Anschlußstutzen aufgesteckt und führt zu dem an dem Führungshandgriff 2 angebrachten Steuerelement 11, das beispielsweise als Dreiwegehahn ausgebildet ist. Dieser Dreiwegehahn besitzt ein drehbares Küken 13, das einen rechtwinkelig ausgebildeten Durchlaßkanal 14 aufweist. In der in Fig. 2 gezeigten Stellung verbindet der Durchlaßkanal 14 den Leitungskanal 10 mit einer in den Führungshandgriff und damit in das Saugrohr mündenden öffnung 15. Durch eine 90 -Drehung des Kükens 13 im Uhrzeigersinn wird über den Durchlaßkanal 14 eine Verbindung zwischen dem Leitungskanal 10 und einem ins Freie mündenden Anschlußstutzen 16 des Dreiwegehahnes hergestellt.The conduit 10 is connected to one of the pressure chamber 9 molded connection piece plugged and leads to the attached to the guide handle 2 control element 11, which is designed for example as a three-way valve. This three-way valve has a rotatable plug 13, which has a right-angled passage 14. In the position shown in FIG. 2, the passage channel 14 connects the line channel 10 with an opening 15 opening into the guide handle and thus into the intake manifold. A 90 rotation of the plug 13 clockwise creates a connection between the line channel 10 via the passage channel 14 and a connecting piece 16 of the three-way valve opening into the open.

Mit Hilfe des Dreiwegehahnes kann der Druckraum 9 somit entweder mit Atmosphärendruck oder mit dem im Saugrohr herrschenden Unterdruck beaufschlagt werden. Dementsprechend wird der Faltenbalg 7 in dem Saugkanal 5 nach oben oder unten bewegt. Bei Beaufschlagung mit Atmosphärendruck wird der Faltenbalg 7 gedehnt und der Fadenheber 8 in dem Saugkanal 5 nach unten gegen die abzusaugende Fläche gedrückt. Wird dagegen der Druckraum 9 mit dem im Saugrohr herrschenden Unterdruck beaufschlagt, so wird der Fadenheber 8 nach oben gezogen, wobei die Zugfeder 12 unterstützend wirkt. Der Fadenheber 8 kann somit nach Bedarf in einfacher Weise vom Führungshandgriff 2 aus in die Betriebs-oder in die Ruhestellung geschaltet werden.With the help of the three-way valve, the pressure chamber 9 can thus be acted upon either with atmospheric pressure or with the negative pressure prevailing in the intake manifold. Accordingly, the bellows 7 is moved up or down in the suction channel 5. When atmospheric pressure is applied, the bellows 7 is stretched and the thread lifter 8 in the suction channel 5 is pressed down against the surface to be extracted. If, on the other hand, the pressure chamber 9 is acted upon by the negative pressure prevailing in the intake manifold, the thread lifter 8 is pulled upwards, the tension spring 12 acting as a support. The thread lifter 8 can thus be switched from the guide handle 2 to the operating or the rest position in a simple manner as required.

Der Fadenheber 8 kann durchgehend über die ganze Breite des Saugmundstückes ausgebildet sein. Es besteht aber auch die Möglichkeit, in den beiden links und rechts. von der Saugöffnung des Saugmundstückes sich erstreckenden- Saugkanalhälften je einen sich nur jeweils über diese Saugkanalhälfte erstreckenden Fadenheber anzuordnen. Jedem Fadenheber wird dann ein eigener Fältenbalg 7 zugeordnet. Wird von jedem durch den entsprechenden Faltenbalg gebildeten Druckraum ein gesonderter Leitungskanal zum Führungshandgriff geführt, so können die in den beiden Saugkanalhälften angeordneten Fadenheber individuell gesteuert werden. Anstelle der Fadenheber können auch andere Zusatzorgane im Saugkanal vorgesehen werden, deren Steuerung dann in der gleichen Weise erfolgt wie die der Fadenheber. Beispielsweise können die beiden Saugkanalhälften durch ein Verschlußorgan gegenüber der Saugöffnung abgeriegelt werden, so daß nur noch im Bereich der Saugöffnung angesaugt wird, wodurch sich eine starke Saugströmung ergibt. Es besteht auch die Möglichkeit, nur eine Saugkanalhälfte abzuriegeln und den Saugluftstrom auf die andere Saugkanalhälfte zu konzentrieren, so daß ein besseres Randsaugen möglich ist.The thread lifter 8 can be formed continuously over the entire width of the suction mouthpiece. But there is also the option of left and right in both. Arrange suction channel halves extending from the suction opening of the suction mouthpiece, one thread lifter each only extending over this suction channel half. Each thread lifter is then assigned its own bellows 7. If a separate conduit is led to the guide handle from each pressure chamber formed by the corresponding bellows, the thread lifters arranged in the two suction channel halves can be controlled individually. Instead of the thread lifters, other additional elements can also be provided in the suction channel, the control of which then takes place in the same way as that of the thread lifters. For example, the two halves of the suction channel can be sealed off from the suction opening by a closure member, so that suction is only carried out in the area of the suction opening, resulting in a strong suction flow. There is also the option of sealing off only one suction channel half and concentrating the suction air flow on the other suction channel half, so that a better edge suction is possible.

Die Steuerung des Zusatzorganes kann auch direkt auf mechanischem Wege vom Führungshandgriff aus erfolgen. Beispielsweise kann am Führungshandgriff ein kleiner Betätigungshebel angeordnet werden, über den ein mit dem Zusatzorgan gekoppelter Bowdenzug betätigt und dadurch das Zusatzorgan in der gewünschten Weise verstellt wird.The control of the additional element can also take place mechanically directly from the guide handle. For example, a small actuating lever can be arranged on the guide handle, via which a Bowden cable coupled to the additional element is actuated and the additional element is thereby adjusted in the desired manner.
