  • a corresponding pivot bearing can be designed in a structurally simple manner.
  • the suction head can be positioned on the suction body in such a way that its axis of rotation is at a minimal distance from the surface to be cleaned. This minimum distance is essentially half the diameter of the suction head.

  • the suction nozzle device can thus be used variably in a simple manner.
  • a guide runner is arranged in each case in the area of opposite end faces of the absorbent body.
  • the guide runners are spaced from one another. This results in an enlarged guide surface, with guide runners being positionable, for example, in such a way that they are at most minimally exposed to spray liquid, that is, the spraying of a surface to be cleaned does not shade the spraying of a surface to be cleaned to a relevant extent.
  • the at least one guide runner is oriented transversely to an axis of rotation of the suction head in order to achieve effective support and thus guidance.
  • the at least one guide runner is oriented in a direction which is parallel to a pulling direction of the suction nozzle device when the cleaning device is in operation. As a result, the at least one guide runner does not protrude beyond a front side of the absorbent body and the absorbent body can be brought close to a transverse wall to the surface to be cleaned.
  • one or more rollers are arranged on the at least one guide runner.

  • the suction head comprises a body on which the at least one suction opening and the at least one outlet opening are arranged, wherein these extend between the at least one suction channel in the body.
  • Suction material is then sucked in through the suction head, that is to say a flow path for the suction leads through the suction head. It can be realized in a simple way that the suction head touches the surface to be cleaned directly or via sealing lips and suction material is then sucked into a suction space following the suction head. As a result, large jumps in cross-section can be avoided in every rotational position of the suction head, and an optimized flow path results.
  • the suction body has a suction space which is in fluid communication with the connection, the at least one suction channel opening into the suction space in every rotational position of the suction head. This results in an optimized connection of the suction head to the suction body with regard to the flow guidance. Large cross-sectional jumps in the flow path can be avoided, so that an optimized suction result is obtained.
  • the suction body comprises a tubular element in which the suction space is formed
  • the suction head comprises at least one immersion element which is immersed in the tubular element, the at least one outlet opening being arranged in the at least one immersion element.
  • the at least one immersion element rests against a wall of the tubular element to form a sliding seal. This results in a sealing effect in every rotary position of the suction head.
  • the at least one immersion element has a rounded end head for rotatability on the tubular element. It can thereby be realized at the same time a rotatability and a sliding seal.
  • a first stop and a second stop for the suction head are provided on the suction body, the suction head being pivotable between the first stop and the second stop relative to the suction body.
  • the first stop and the second stop are formed in particular by corresponding structural measures on the suction head and the suction body.

  • the suction nozzle device has a spray connection which is in fluid communication with the at least one spray nozzle.
  • Spray liquid can be coupled into the suction nozzle device via the spray connection.

Aus der EP 1 880 651 B1 ist eine Sprühextraktionsdüse mit einem Saugkanal und einem Saugmund sowie einer dieser zugeordneten Sprühdüse und mit einem Adapter zur Bearbeitung von Oberflächen, die unterschiedliche Beschaffenheiten aufweisen, bekannt.

Der Adapter dient in seiner Ruhestellung als Auflagefläche für die Sprühextraktionsdüse.From the EP 1 880 651 B1 a spray extraction nozzle with a suction channel and a suction mouth and a spray nozzle assigned to this and with an adapter for processing surfaces that have different properties is known. The adapter is connected to the spray extraction nozzle via a pivot axis and can be pivoted from a rest position away from the suction mouth into a working position in front of the suction mouth of the spray extraction nozzle.

The suction head has a suction opening each on its underside and on its front face, and one of the two suction openings can be closed.

Aus der WO 87/01920 A1 ist eine variable Reinigungsdüse bekannt.From the WO 87/01920 A1 a variable cleaning nozzle is known.

Aus der DE 10 2011 050 697 A1 ist eine Flüssigkeitssaugvorrichtung zum Abziehen und Aufsaugen von Flüssigkeiten bekannt.From the DE 10 2011 050 697 A1 a liquid suction device for drawing off and sucking up liquids is known.

Der Erfindung liegt die Aufgabe zugrunde, eine Saugdüsenvorrichtung der eingangs genannten Art bereitzustellen, welche bei konstruktiv einfacher Ausbildung optimierte Saugeigenschaften aufweist.The invention is based on the object of providing a suction nozzle device of the type mentioned at the beginning, which has optimized suction properties with a structurally simple design.

Diese Aufgabe wird bei der eingangs genannten Saugdüsenvorrichtung erfindungsgemäß dadurch gelöst, dass mindestens eine Sprühdüse zur Sprühbeaufschlagung einer zu reinigenden Fläche vorgesehen ist, wobei die Drehachse in einer festen Position zu der mindestens einen Sprühdüse ist.This object is achieved according to the invention in the suction nozzle device mentioned at the outset in that at least one spray nozzle is provided for spraying a surface to be cleaned, the axis of rotation being in a fixed position relative to the at least one spray nozzle.

Über den Saugkörper erfolgt eine Einsaugung. Der Saugkörper kontaktiert dabei direkt die zu reinigende Fläche oder beispielsweise über Lippen wie Gummilippen.Suction takes place via the absorbent body. The absorbent body makes direct contact with the surface to be cleaned or, for example, via lips such as rubber lips.

Durch die Drehbarkeit des Saugkopfs kann eine Winkellage der Saugdüsenvorrichtung zu der reinigenden Fläche eingestellt werden. Dadurch ist auf einfache Weise und insbesondere selbsttätige Weise eine Anpassung an unterschiedliche Größen eines Bedieners möglich. Insbesondere ist, wenn eine Besprühung der zu reinigenden Fläche mit Reinigungsflüssigkeit vorgesehen ist, ein gleiches Sprühbild unabhängig von der Winkelposition der Saugdüsenvorrichtung zu der zu reinigenden Fläche erreicht.The rotatability of the suction head means that an angular position of the suction nozzle device in relation to the cleaning surface can be set. As a result, an adaptation to different sizes of an operator is possible in a simple manner and in particular automatically. In particular, if the surface to be cleaned is sprayed with cleaning fluid, the same spray pattern is achieved regardless of the angular position of the suction nozzle device in relation to the surface to be cleaned.

Es ist mindestens eine Sprühdüse zur Sprühbeaufschlagung einer zu reinigenden Fläche vorgesehen. Es lässt sich dadurch eine zu reinigende Fläche zuerst mit Reinigungsflüssigkeit besprühen und anschließend lässt sich überschüssige Flüssigkeit aufnehmen. Durch die Reinigungsflüssigkeit lässt sich Schmutz anlösen und aufnehmen. Beispielsweise ist die entsprechende Saugdüsenvorrichtung dann eine Sprühextraktions-Saugdüsenvorrichtung. Es kann beispielsweise auch vorgesehen sein, dass über die mindestens eine Sprühdüse Dampf auf die zu reinigende Fläche ausgesprüht wird.At least one spray nozzle is provided for spraying a surface to be cleaned. As a result, a surface to be cleaned can first be sprayed with cleaning liquid and then excess liquid can be absorbed. The cleaning fluid can loosen and absorb dirt. For example, the corresponding suction nozzle device is then a spray extraction suction nozzle device. It can also be provided, for example, that steam is sprayed onto the surface to be cleaned via the at least one spray nozzle.

Durch die Innenlagerung des Saugkopfs an dem Gehäuse ist dieser geschützt. Ein entsprechendes Drehlager lässt sich auf konstruktiv einfache Weise ausbilden.The internal bearing of the suction head on the housing protects it. A corresponding pivot bearing can be designed in a structurally simple manner.

Ferner lässt sich der Saugkopf so an dem Saugkörper positionieren, dass seine Drehachse einen minimalen Abstand zu der zu reinigenden Fläche hat. Dieser minimale Abstand ist im Wesentlichen der halbe Durchmesser des Saugkopfs.Furthermore, the suction head can be positioned on the suction body in such a way that its axis of rotation is at a minimal distance from the surface to be cleaned. This minimum distance is essentially half the diameter of the suction head.

Bei einer entsprechenden konstruktiv einfachen Ausbildung eines Drehlagers lässt sich der Saugkopf auch auf einfache Weise und insbesondere werkzeugfrei von dem Saugkörper beispielsweise für Reinigungszwecke abnehmen und wieder einsetzen.With a corresponding, structurally simple design of a pivot bearing, the suction head can also be designed in a simple manner and in particular without tools remove from the absorbent body, for example for cleaning purposes, and reinsert it.

Durch die Lagerung des Saugkopfs in dem Innenraum des Gehäuses des Saugkörpers lässt sich ein Fluidweg für die Einsaugung realisieren, welcher unabhängig von der Drehstellung des Saugkopfs an dem Saugkörper minimierte Querschnittssprünge aufweist. Dadurch ergibt sich ein optimiertes Saugergebnis mit minimierten Strömungsverlusten.By mounting the suction head in the interior of the housing of the suction body, a fluid path for suction can be implemented which has minimized cross-sectional jumps regardless of the rotational position of the suction head on the suction body. This results in an optimized suction result with minimized flow losses.

Insbesondere weist das Gehäuse des Saugkörpers eine erste Wand und eine gegenüberliegende zweite Wand auf, zwischen welchen der Saugkopf positioniert ist. Die Wände lassen sich insbesondere zur Ausbildung eines Drehlagers verwenden. Es ergibt sich dadurch ein kompakter Aufbau mit einer geschützten Lagerung des Saugkopfs.In particular, the housing of the suction body has a first wall and an opposing second wall, between which the suction head is positioned. The walls can be used in particular to form a pivot bearing. This results in a compact structure with a protected mounting of the suction head.

Es ist dann vorteilhaft, wenn an der ersten Wand und der zweiten Wand jeweils Aufnahmen zur Drehlagerung des Saugkopfs angeordnet sind. Dadurch lässt sich ein entsprechendes Drehlager auf konstruktiv einfache und fertigungstechnisch einfache Weise ausbilden.It is then advantageous if receptacles for the rotary bearing of the suction head are arranged on the first wall and the second wall. As a result, a corresponding pivot bearing can be designed in a structurally simple and technically simple manner in terms of production.

Insbesondere ist eine jeweilige Aufnahme als Ausnehmung an der entsprechenden Wand ausgebildet. Es lässt sich dadurch ein Teil des Drehlagers gewissermaßen als Loch ausbilden. Es ist dabei vorteilhaft, wenn mindestens eine Aufnahme als durchgehende Ausnehmung ausgebildet ist. Dadurch kann ein Bediener von außen her durch entsprechende Druckausübung den Saugkopf von dem Saugkörper lösen.In particular, a respective receptacle is designed as a recess on the corresponding wall. As a result, part of the pivot bearing can be designed as a hole, so to speak. It is advantageous if at least one receptacle is designed as a continuous recess. As a result, an operator can detach the suction head from the suction body from the outside by applying appropriate pressure.

Konstruktiv günstig ist es, wenn dem Saugkopf gegenüberliegende Wellenstummel zur Drehlagerung am Saugkörper angeordnet sind. Die Wellenstummel sind dabei insbesondere drehfest an dem Saugkörper angeordnet. Bei entsprechendem Eintauchen in eine zugeordnete Aufnahme lässt sich auf einfache Weise eine Drehbarkeit beziehungsweise Schwenkbarkeit des Saugkopfs an dem Saugkörper realisieren.It is structurally favorable if shaft stubs opposite the suction head are arranged on the suction body for rotary mounting. The stub shafts are in particular arranged in a rotationally fixed manner on the suction body. With appropriate immersion in an assigned receptacle, the suction head can be rotated or pivoted on the suction body in a simple manner.

Günstig ist es, wenn mindestens ein Wellenstummel parallel zu einer Drehachse des Saugkopfs verschieblich ist. Dadurch lässt sich auf einfache Weise ein von dem Saugkörper lösbarer Saugkopf realisieren, wobei die Lösbarkeit (und auch Einsetzbarkeit) insbesondere werkzeugfrei möglich ist.It is favorable if at least one shaft stub is displaceable parallel to an axis of rotation of the suction head. In this way, a suction head that can be detached from the absorbent body can be implemented in a simple manner, the detachability (and also use) being possible in particular without tools.

Es ist dann günstig, wenn der mindestens eine verschiebliche Wellenstummel federbelastet ist, wobei zur Verschiebung des entsprechenden Wellenstummels in Richtung zu dem anderen Wellenstummel hin eine Federkraft überwunden werden muss. Die Federkraft drückt den verschieblichen Wellenstummel in eine Position, welche eine Drehlagerung des Saugkopfs an dem Saugkörper ermöglicht. Durch Verschiebung des entsprechenden Wellenstummels entgegen der Richtung der Federkraft, wobei hierzu ein Bedienerzugriff notwendig ist, kann ein entsprechender Wellenstummel aus seiner Aufnahme ausgetaucht werden und dadurch kann der Saugkopf von dem Saugkörper abgenommen werden.It is then advantageous if the at least one displaceable shaft stub is spring-loaded, a spring force having to be overcome in order to move the corresponding shaft stub in the direction of the other shaft stub. The spring force presses the displaceable shaft stub into a position which enables the suction head to be pivoted on the suction body. By shifting the corresponding stub shaft against the direction of the spring force, which requires operator access, a corresponding stub shaft can be removed from its receptacle and the suction head can thereby be removed from the suction body.

Insbesondere ist dann der Saugkopf werkzeugfrei abnehmbar und einsetzbar an dem Saugkörper positioniert. Dadurch kann ein Bediener auf einfache Weise den Saugkopf beispielsweise zur Reinigung austauschen. Es ist dadurch auch möglich, die Saugdüsenvorrichtung auf einfache Weise an unterschiedliche Anwendungen und dabei insbesondere an unterschiedliche Typen von zu reinigenden Flächen anzupassen. Es kann beispielsweise ein spezieller Saugkopf für Hartböden vorgesehen werden, welcher beispielsweise Rollen zur Rollenführung an dem Hartboden aufweist und Abziehlippen aufweist. Es kann ferner ein entsprechender Saugkopf zur Reinigung von textilen Materialien wie Teppichböden vorgesehen werden. Es ergibt sich dadurch eine variable Einsetzbarkeit der entsprechenden Saugdüsenvorrichtung.In particular, the suction head is then positioned on the suction body so that it can be removed and used without tools. As a result, an operator can easily replace the suction head, for example for cleaning. It is thereby also possible to adapt the suction nozzle device in a simple manner to different applications and in particular to different types of surfaces to be cleaned. For example, a special suction head for hard floors can be provided, which has, for example, rollers for guiding rollers on the hard floor and has pull-off lips. A corresponding suction head can also be provided for cleaning textile materials such as carpets. This results in a variable usability of the corresponding suction nozzle device.

Günstig ist es, wenn der Saugkopf als Welle ausgebildet ist und dabei insbesondere als Ganzes als Welle ausgebildet ist. Diese Welle, welche insbesondere Wellenstummel aufweist, ist als Ganzes drehbar in dem Gehäuseinnenraum des Saugkörpers positioniert.It is favorable if the suction head is designed as a shaft and, in particular, is designed as a shaft as a whole. This shaft, which in particular has shaft stubs, is rotatably positioned as a whole in the housing interior of the suction body.

Es ist günstig, wenn an dem Saugkörper ein Gleitlager für den Saugkopf angeordnet ist, wobei insbesondere eine Gleitdichtung zwischen dem Saugkörper und dem Saugkopf gebildet ist. Durch das Gleitlager erhält man eine zusätzliche Abstützung für die Drehbarkeit des Saugkopfs in dem Saugkörper. Gleichzeitig lässt sich dadurch eine Gleitdichtung ausbilden, so dass der Strömungsweg für den Eintritt in den Saugkörper im Wesentlichen nur durch den Saugkopf und dabei dort durch die Einsaugöffnung hindurch vorgegeben ist.It is advantageous if a slide bearing for the suction head is arranged on the suction body, in particular a sliding seal being formed between the suction body and the suction head. The slide bearing provides additional support for the rotatability of the suction head in the suction body. At the same time, a sliding seal can thereby be formed, so that the flow path for entry into the absorbent body is defined essentially only through the suction head and through the suction opening there.

Insbesondere weisen im Bereich des Gleitlagers der Saugkörper und der Saugkopf aneinander angepasste Zylinderkonturen auf. Dadurch ist auf einfache Weise eine Drehbarkeit des Saugkopfs in dem Gleitlager ermöglicht.In particular, in the area of the sliding bearing, the suction body and the suction head have cylinder contours that are adapted to one another. This enables the suction head to be rotatable in the plain bearing in a simple manner.

Ganz besonders vorteilhaft ist es, wenn an dem Saugkörper mindestens eine Führungskufe zur Auflage auf eine zu reinigende Fläche angeordnet ist. Dadurch wird eine vergrößerte Führungsfläche bereitgestellt. Durch die entsprechende vergrößerte Führungsfläche und damit auch durch eine vergrößerte Auflagefläche kann auf einfache Weise durch Anpassung einer Winkelstellung der Saugdüsenvorrichtung zu der zu reinigenden Fläche eine Anpassung an eine Bedienergröße erfolgen. Die Saugdüsenvorrichtung ist dadurch auf einfache Weise variabel einsetzbar.It is particularly advantageous if at least one guide runner is arranged on the absorbent body for resting on a surface to be cleaned. This provides an enlarged guide surface. By means of the corresponding enlarged guide surface and thus also by means of an enlarged contact surface, an adaptation to the size of the operator can be carried out in a simple manner by adapting an angular position of the suction nozzle device to the surface to be cleaned. The suction nozzle device can thus be used variably in a simple manner.

Insbesondere ist im Bereich gegenüberliegender Stirnseiten des Saugkörpers jeweils eine Führungskufe angeordnet. Die Führungskufen sind beabstandet zueinander. Es ergibt sich dadurch eine vergrößerte Führungsfläche, wobei Führungskufen beispielsweise so positionierbar sind, dass diese höchstens minimal mit Sprühflüssigkeit beaufschlagt werden, das heißt die Besprühung einer zu reinigenden Fläche nicht in relevantem Umfange abschatten.In particular, a guide runner is arranged in each case in the area of opposite end faces of the absorbent body. The guide runners are spaced from one another. This results in an enlarged guide surface, with guide runners being positionable, for example, in such a way that they are at most minimally exposed to spray liquid, that is, the spraying of a surface to be cleaned does not shade the spraying of a surface to be cleaned to a relevant extent.

Insbesondere ist die mindestens eine Führungskufe quer zu einer Drehachse des Saugkopfs orientiert, um eine effektive Auflage und damit Führung zu erreichen.In particular, the at least one guide runner is oriented transversely to an axis of rotation of the suction head in order to achieve effective support and thus guidance.

Es ist dabei günstig, wenn die mindestens eine Führungskufe in einer Richtung orientiert ist, welche parallel zu einer Ziehrichtung der Saugdüsenvorrichtung beim Betrieb des Reinigungsgeräts ist. Dadurch ragt die mindestens eine Führungskufe nicht über eine Vorderseite des Saugkörpers hinaus und der Saugkörper lässt sich dicht an eine Querwand zu der zu reinigenden Fläche heranführen.It is advantageous if the at least one guide runner is oriented in a direction which is parallel to a pulling direction of the suction nozzle device when the cleaning device is in operation. As a result, the at least one guide runner does not protrude beyond a front side of the absorbent body and the absorbent body can be brought close to a transverse wall to the surface to be cleaned.

Bei einem Ausführungsbeispiel sind an der mindestens einen Führungskufe eine oder mehrere Rollen angeordnet. Es lässt sich dadurch insbesondere ein Saugkopf realisieren, welcher vorteilhaft für die Reinigung von Hartböden ist. Beispielsweise für die Reinigung von textilen Materialien sind in der Regel solche Rollen nicht vorgesehen.In one embodiment, one or more rollers are arranged on the at least one guide runner. In particular, a suction head can thereby be implemented, which is advantageous for cleaning hard floors. Such roles are usually not provided for cleaning textile materials, for example.

Es ist ferner günstig, wenn eine Auflagefläche der mindestens einen Führungskufe für die zu reinigende Fläche parallel zu einer Drehachse des Saugkopfs orientiert ist. Es ergibt sich dadurch eine optimierte Führung.It is also advantageous if a support surface of the at least one guide runner for the surface to be cleaned is oriented parallel to an axis of rotation of the suction head. This results in optimized guidance.

Günstig ist es, wenn der Saugkopf mindestens einen Saugkanal aufweist, welcher sich zwischen mindestens einer Auslassöffnung und der mindestens einen Einsaugöffnung erstreckt. Der Saugkopf umfasst einen Körper, an welchem die mindestens eine Einsaugöffnung und die mindestens eine Auslassöffnung angeordnet sind, wobei sich diese zwischen dem mindestens einen Saugkanal in dem Körper erstrecken. Es wird dann Sauggut durch den Saugkopf hindurch eingesaugt, das heißt ein Strömungsweg für das Einsaugen führt durch den Saugkopf hindurch. Es lässt sich dadurch auf einfache Weise realisieren, dass der Saugkopf direkt oder über Dichtlippen die zu reinigende Fläche berührt und Sauggut wird dann in einen Saugraum nachfolgend dem Saugkopf eingesaugt. Dadurch wiederum lassen sich bei jeder Drehstellung des Saugkopfs große Querschnittssprünge vermeiden und es ergibt sich ein optimierter Strömungsweg.It is favorable if the suction head has at least one suction channel which extends between at least one outlet opening and the at least one suction opening. The suction head comprises a body on which the at least one suction opening and the at least one outlet opening are arranged, wherein these extend between the at least one suction channel in the body. Suction material is then sucked in through the suction head, that is to say a flow path for the suction leads through the suction head. It can be realized in a simple way that the suction head touches the surface to be cleaned directly or via sealing lips and suction material is then sucked into a suction space following the suction head. As a result, large jumps in cross-section can be avoided in every rotational position of the suction head, and an optimized flow path results.

Es ist dann günstig, wenn der Saugkörper einen Saugraum aufweist, welcher in fluidwirksamer Verbindung mit dem Anschluss steht, wobei der mindestens eine Saugkanal in den Saugraum bei jeder Drehstellung des Saugkopfs mündet. Dadurch ergibt sich ein optimierter Anschluss des Saugkopfs an den Saugkörper bezüglich der Strömungsführung. Es lassen sich große Querschnittssprünge im Strömungsweg vermeiden, so dass sich ein optimiertes Absaugergebnis ergibt.It is then favorable if the suction body has a suction space which is in fluid communication with the connection, the at least one suction channel opening into the suction space in every rotational position of the suction head. This results in an optimized connection of the suction head to the suction body with regard to the flow guidance. Large cross-sectional jumps in the flow path can be avoided, so that an optimized suction result is obtained.

Bei einem Ausführungsbeispiel umfasst der Saugkörper ein Rohrelement, in welchem der Saugraum gebildet ist, und der Saugkopf umfasst mindestens ein Eintauchelement, welches in das Rohrelement eingetaucht ist, wobei in dem mindestens einen Eintauchelement die mindestens eine Auslassöffnung angeordnet ist. Dadurch ergibt sich ein optimierter Übergang bezüglich der Strömungsführung von dem Saugkopf zu dem Saugkörper. Zwischen dem mindestens einen Eintauchelement und dem Rohrelement lässt sich auf einfache Weise eine Abdichtung insbesondere über eine Gleitdichtung erreichen, so dass der Strömungsweg im Wesentlichen über den mindestens einen Saugkanal im Saugkopf und den Saugraum definiert ist.In one embodiment, the suction body comprises a tubular element in which the suction space is formed, and the suction head comprises at least one immersion element which is immersed in the tubular element, the at least one outlet opening being arranged in the at least one immersion element. This results in an optimized transition with regard to the flow guidance from the suction head to the suction body. A seal can be achieved in a simple manner between the at least one immersion element and the tubular element, in particular via a sliding seal, so that the flow path is essentially defined via the at least one suction channel in the suction head and the suction space.

Es ist dann günstig, wenn das mindestens eine Eintauchelement zur Bildung einer Gleitdichtung an einer Wandung des Rohrelements anliegt. Dadurch ergibt sich bei jeder Drehstellung des Saugkopfs eine Dichtwirkung.It is then advantageous if the at least one immersion element rests against a wall of the tubular element to form a sliding seal. This results in a sealing effect in every rotary position of the suction head.

Es kann vorgesehen sein, dass das mindestens eine Eintauchelement zur Drehbarkeit an dem Rohrelement einen abgerundeten Stirnkopf aufweist. Es lässt sich dadurch gleichzeitig eine Drehbarkeit realisieren und eine Gleitdichtung realisieren.It can be provided that the at least one immersion element has a rounded end head for rotatability on the tubular element. It can thereby be realized at the same time a rotatability and a sliding seal.

Bei einem Ausführungsbeispiel sind ein erster Anschlag und ein zweiter Anschlag für den Saugkopf an dem Saugkörper vorgesehen, wobei der Saugkopf zwischen dem ersten Anschlag und dem zweiten Anschlag relativ zu dem Saugkörper schwenkbar ist. Dadurch lässt sich auf einfache Weise eine an einen Bediener angepasste Winkelstellung der Saugdüsenvorrichtung zu der zu reinigenden Fläche einstellen. Der erste Anschlag und der zweite Anschlag sind insbesondere durch entsprechende konstruktive Maßnahmen an dem Saugkopf und dem Saugkörper gebildet. Beispielsweise ist ein Anschlag dadurch gebildet, dass eine oder mehrere Führungskufen an einen bestimmten Bereich des Saugkörpers anschlagen. Ein weiterer Anschlag ist beispielsweise dadurch gebildet, dass ein Anschlagelement des Saugkopfs wie eine Anschlagleiste an einen entsprechenden Gehäuseteil des Saugkörpers anschlägt.In one embodiment, a first stop and a second stop for the suction head are provided on the suction body, the suction head being pivotable between the first stop and the second stop relative to the suction body. In this way, an angular position of the suction nozzle device that is adapted to an operator can be achieved in a simple manner set the cleaning surface. The first stop and the second stop are formed in particular by corresponding structural measures on the suction head and the suction body. For example, a stop is formed in that one or more guide runners strike a specific area of the absorbent body. Another stop is formed, for example, in that a stop element of the suction head strikes a corresponding housing part of the suction body like a stop bar.

Insbesondere ist die Drehbarkeit zwischen dem ersten Anschlag und dem zweiten Anschlag stufenlos. Eine solche stufenlose Drehbarkeit lässt sich auf einfache Weise über ein entsprechendes Drehlager realisieren. Insbesondere ist dabei der Saugkopf als Ganzes als Welle ausgebildet. Es ergibt sich dadurch eine einfache Anpassung an unterschiedliche Benutzergrößen und auch für bestimmte Reinigungszwecke lässt sich die Winkelstellung der Saugdüsenvorrichtung zu der zu reinigenden Fläche variabel einstellen.In particular, the rotatability between the first stop and the second stop is stepless. Such an infinitely variable rotatability can be implemented in a simple manner using a corresponding rotary bearing. In particular, the suction head is designed as a shaft as a whole. This results in a simple adaptation to different user sizes and the angular position of the suction nozzle device in relation to the surface to be cleaned can also be set variably for certain cleaning purposes.

Es ist dann günstig, wenn die Saugdüsenvorrichtung einen Sprühanschluss aufweist, welcher in fluidwirksamer Verbindung mit der mindestens einen Sprühdüse steht. Über den Sprühanschluss lässt sich Sprühflüssigkeit in die Saugdüsenvorrichtung einkoppeln.It is then favorable if the suction nozzle device has a spray connection which is in fluid communication with the at least one spray nozzle. Spray liquid can be coupled into the suction nozzle device via the spray connection.

Bei einem Ausführungsbeispiel ist die mindestens eine Sprühdüse beabstandet zu dem Saugkopf positioniert. Es handelt sich dann insbesondere um eine Sprühextraktions-Saugdüsenvorrichtung. Es wird die zu reinigende Fläche über die mindestens eine Sprühdüse mit Sprühflüssigkeit besprüht, bevor eine Einsaugung stattfindet. Bei der erfindungsgemäßen Lösung liegt die Drehachse in einer festen Position zu der mindestens einen Sprühdüse. Dies bedeutet, dass bei jeder Winkelstellung der Saugdüsenvorrichtung das gleiche Sprühbild an der zu reinigenden Fläche erhalten wird.In one embodiment, the at least one spray nozzle is positioned at a distance from the suction head. It is then in particular a Spray extraction suction nozzle device. The surface to be cleaned is sprayed with spray liquid via the at least one spray nozzle before suction takes place. In the solution according to the invention, the axis of rotation lies in a fixed position in relation to the at least one spray nozzle. This means that the same spray pattern is obtained on the surface to be cleaned in every angular position of the suction nozzle device.

Bei einem Ausführungsbeispiel ist ein Halter vorgesehen, an welchem die mindestens eine Sprühdüse und der Saugkörper fixiert sind. Dadurch ergibt sich ein kompakter Aufbau der Saugdüsenvorrichtung. Ferner wird eine feste Abstandsrelation zwischen der mindestens einen Sprühdüse und dem Saugkopf eingestellt.In one embodiment, a holder is provided on which the at least one spray nozzle and the suction body are fixed. This results in a compact construction of the suction nozzle device. Furthermore, a fixed distance relationship is set between the at least one spray nozzle and the suction head.

Vor dem Halter liegt ein Vorderraum und hinter dem Halter liegt ein Hinterraum, wobei der Halter gewissermaßen den Vorderraum und den Hinterraum deckt. Es ist dann günstig, wenn die mindestens eine Sprühdüse in dem Hinterraum positioniert ist und im Normalbetrieb des Reinigungsgeräts der Saugkopf in einer Ziehrichtung, welche vom Vorderraum zum Hinterraum weist, gezogen wird. Es lässt sich dadurch zuerst ein bestimmter Bereich der zu reinigenden Fläche besprühen und anschließend wird durch das Ziehen der Saugdüsenvorrichtung in der Ziehrichtung der Saugkopf in Kontakt mit dem zuvor besprühten Flächenbereich gebracht und es lässt sich überschüssige Flüssigkeit insbesondere mit gelöstem Schmutz einsaugen.In front of the holder there is a front space and behind the holder there is a rear space, the holder to a certain extent covering the front space and the rear space. It is then favorable if the at least one spray nozzle is positioned in the rear space and, during normal operation of the cleaning device, the suction head is pulled in a pulling direction which points from the front space to the rear space. A certain area of the surface to be cleaned can first be sprayed and then the suction head is brought into contact with the previously sprayed surface area by pulling the suction nozzle device in the pulling direction and excess liquid, especially with loosened dirt, can be sucked in.

Die Saugdüsenvorrichtung 18 umfasst ein Griffstück 24. An dem Griffstück 24 ist ein flexibler Schlauch 26 gehalten. Der Schlauch 26 weist einen Anschluss 28 zur Unterdruckbeaufschlagung auf. Dieser Anschluss 28 der Saugdüsenvorrichtung 18 ist an den Sauganschluss 16 anschließbar.The suction nozzle device 18 comprises a handle 24. A flexible hose 26 is held on the handle 24. The hose 26 has a connection 28 for applying negative pressure. This connection 28 of the suction nozzle device 18 can be connected to the suction connection 16.

An dem Griffstück 24 ist eine Schalteinrichtung 30 angeordnet, über den ein Saugbetrieb und/oder Sprühbetrieb schaltbar ist.A switching device 30 is arranged on the handle 24, via which a suction mode and / or spray mode can be switched.

An dem Griffstück 24 sitzt an einer Seite, welche derjenigen Seite abgewandt ist, an welcher der Schlauch 26 positioniert ist, ein Rohrstück 32. Dieses Rohrstück 32 umfasst ein starres Rohr. Auf dem Rohrstück 32 sitzt ein Bügelgriff 34, über welchen ein Bediener die Saugdüsenvorrichtung 18 halten kann.A pipe section 32 is seated on the handle piece 24 on a side facing away from the side on which the hose 26 is positioned. This pipe section 32 comprises a rigid tube. A bow-type handle 34, via which an operator can hold the suction nozzle device 18, is seated on the pipe section 32.

Das Rohrstück 32 ist insbesondere mittels einer Überwurfmutter 36 an einem Gewinde des Griffstücks 24 fixiert.The pipe section 32 is fixed to a thread of the handle piece 24 in particular by means of a union nut 36.

An dem Rohrstück 32 sitzt ein weiteres Rohrstück 38, welches über eine Überwurfmutter 40 an einem Gewinde des Rohrstücks 32 fixiert ist.Another pipe section 38 is seated on the pipe section 32 and is fixed to a thread of the pipe section 32 via a union nut 40.

An dem Rohrstück 38 wiederum sitzt eine Saugdüse 42.A suction nozzle 42 is in turn seated on the pipe section 38.

Bei einem Ausführungsbeispiel ist die Saugdüse 42 mittels einer Überwurfmutter 44 an einem Gewinde des Rohrstücks 38 fixiert. Die Saugdüse 42 umfasst einen Saugkörper 46 mit einem Gehäuse 48. An dem Gehäuse 48 sitzt ein Rohrstück 50, welches mit der Überwurfmutter 44 mit dem Rohrstück 38 verbunden ist.In one embodiment, the suction nozzle 42 is fixed to a thread of the pipe section 38 by means of a union nut 44. The suction nozzle 42 comprises a suction body 46 with a housing 48. A pipe section 50 is seated on the housing 48 and is connected to the pipe section 38 by the union nut 44.

Über den Saugkörper 46 lässt sich Fluid einsaugen. Es ist ein Fluidtransportweg durch den Saugkörper 46, das Rohrstück 50, das Rohrstück 38, das Rohrstück 32 und das Griffstück 24 durch den Schlauch 26 bis zum Anschluss 28 bereitgestellt, so dass Fluid (schmutzbehaftetes Fluid, welches auch Flüssigkeit enthalten kann) durch das Reinigungsgerät 10 über den Sauganschluss 16 einsaugbar ist.Fluid can be sucked in via the absorbent body 46. A fluid transport path is provided through the suction body 46, the pipe section 50, the pipe section 38, the pipe section 32 and the handle piece 24 through the hose 26 to the connection 28, so that fluid (contaminated fluid, which can also contain liquid) through the cleaning device 10 can be sucked in via the suction connection 16.

Das Rohrstück 38 bildet einen Halter 52 für die Saugdüse 42 an dem Saugkörper 46. Dieser Halter 52 hält auch eine Sprühdüse 54 (Figuren 2 und 4). Die Saugdüsenvorrichtung 18 hat einen Sprühanschluss 56 (Figur 2), welcher an den Bereitstellungsanschluss 20 anschließbar ist. Von diesem Sprühanschluss 56 ausgehend verläuft eine Leitung 58 für Sprühflüssigkeit entlang des Griffstücks 24, des Rohrstücks 32, des Rohrstücks 38 und teilweise entlang des Rohrstücks 50 bis zu der Sprühdüse 54.The pipe section 38 forms a holder 52 for the suction nozzle 42 on the suction body 46. This holder 52 also holds a spray nozzle 54 ( Figures 2 and 4th ). The suction nozzle device 18 has a spray connection 56 ( Figure 2 ), which can be connected to the supply connection 20. Starting from this spray connection 56, a line 58 for spray liquid runs along the handle piece 24, the tube piece 32, the tube piece 38 and partly along the tube piece 50 up to the spray nozzle 54.

Die Sprühdüse 50 selber ist beabstandet zu dem Rohrstück 50 an einer Unterseite 60 des Halters 52 angeordnet und beabstandet zu dem Saugkörper 46.The spray nozzle 50 itself is arranged at a distance from the pipe section 50 on an underside 60 of the holder 52 and at a distance from the suction body 46.

In einer normalen Bedienungsposition ist das Rohrstück 50 in einem spitzen Winkel 62 zu einer zu reinigenden Fläche 64 geneigt. Die Unterseite 60 weist dann zu der zu reinigenden Fläche 64 zu.In a normal operating position, the pipe section 50 is inclined at an acute angle 62 to a surface 64 to be cleaned. The bottom 60 then faces the surface 64 to be cleaned.

Die Sprühdüse 54 ist so ausgerichtet, dass ein Bereich 66 der zu reinigenden Fläche 64, welcher vor dem Saugkörper 46 liegt, angesprüht wird.The spray nozzle 54 is oriented in such a way that an area 66 of the surface 64 to be cleaned which lies in front of the absorbent body 46 is sprayed on.

Durch den Halter 52 wird der Raum, in welchem der Halter 52 positioniert ist, in einen Vorderraum 68 und einen Hinterraum 70 unterteilt. Die Sprühdüse 54 ist in dem Hinterraum 70 positioniert. In einem Normalbetrieb der Saugdüsenvorrichtung 18 an dem Reinigungsgerät 10 wird diese in einer Ziehrichtung 72, welche von dem Vorderraum 68 in den Hinterraum 70 weist, gezogen.By means of the holder 52, the space in which the holder 52 is positioned is divided into a front space 68 and a rear space 70. The spray nozzle 54 is positioned in the rear space 70. In normal operation of the suction nozzle device 18 on the cleaning device 10, it is pulled in a pulling direction 72 which points from the front space 68 into the rear space 70.

Das Gehäuse 48 des Saugkörpers 46 weist einen Gehäuseinnenraum 74 auf. In diesem Gehäuseinnenraum 74 ist ein Saugkopf 76 um eine Drehachse 78 drehbar angeordnet.The housing 48 of the suction body 46 has a housing interior 74. In this housing interior 74, a suction head 76 is arranged rotatably about an axis of rotation 78.

Wenn der Saugkopf 76 an der zu reinigenden Fläche 64 anliegt, dann ist die Drehachse 78 parallel zu der zu reinigenden Fläche 64.When the suction head 76 rests against the surface 64 to be cleaned, the axis of rotation 78 is parallel to the surface 64 to be cleaned.

Das Gehäuse 48 weist gegenüberliegend beabstandet eine erste Wand 80 und eine zweite Wand 82 auf (Figuren 5 und 6). Zwischen der ersten Wand 80 und der zweiten Wand 82 ist der Saugkopf 76 positioniert.The housing 48 has a first wall 80 and a second wall 82 at a distance from one another ( Figures 5 and 6th ). The suction head 76 is positioned between the first wall 80 and the second wall 82.

Die erste Wand 80 weist eine Aufnahme 84 auf. Die Aufnahme 84 ist durch eine Ausnehmung gebildet, welche insbesondere hohl-zylindrisch ist.The first wall 80 has a receptacle 84. The receptacle 84 is formed by a recess which is in particular hollow-cylindrical.

Die zweite Wand 82 weist eine entsprechende Aufnahme 86 auf, welche ebenfalls als Ausnehmung an der zweiten Wand 82 und insbesondere als hohl-zylindrische Ausnehmung ausgebildet ist.The second wall 82 has a corresponding receptacle 86, which is also designed as a recess on the second wall 82 and in particular as a hollow-cylindrical recess.

Der Saugkopf 76 umfasst einen Körper 88. Dieser Körper 88 ist zumindest näherungsweise zylindrisch ausgebildet.The suction head 76 comprises a body 88. This body 88 is at least approximately cylindrical.

Der Körper 88 hat der ersten Wand 80 zugewandt eine erste Stirnseite 90 und der zweiten Wand 82 zugewandt eine zweite Stirnseite 92. An der ersten Stirnseite 90 sitzt ein erster Wellenstummel 94, welcher zylindrisch ausgebildet ist und in der Aufnahme 84 positioniert ist. Entsprechend sitzt an der zweiten Stirnseite 92 ein zweiter Wellenstummel 96, welcher ebenfalls zylindrisch ausgebildet ist und in der Aufnahme 86 positioniert ist.The body 88 has a first end face 90 facing the first wall 80 and a second end face 92 facing the second wall 82. A first shaft stub 94, which is cylindrical and is positioned in the receptacle 84, sits on the first end face 90. Correspondingly, a second shaft stub 96 is seated on the second end face 92, which is likewise cylindrical and is positioned in the receptacle 86.

Durch den ersten Wellenstummel 94 mit zugehöriger Aufnahme 84 und dem zweiten Wellenstummel 96 mit zugehöriger Aufnahme 86 ist ein Drehlager 98 gebildet, über welches der Saugkopf 76 drehbar in dem Gehäuseinnenraum 74 gelagert ist.A rotary bearing 98 is formed by the first stub shaft 94 with an associated receptacle 84 and the second stub shaft 96 with an associated receptacle 86, via which the suction head 76 is rotatably mounted in the housing interior 74.

Der Saugkopf 76 bildet mit seinen Wellenstummeln 94 und 96 eine drehbar an dem Gehäuse 48 und in dem Gehäuseinnenraum 74 zwischen der ersten Wand 80 und der zweiten Wand 82 positionierte Welle.The suction head 76 with its stub shafts 94 and 96 forms a shaft which is rotatably positioned on the housing 48 and in the housing interior 74 between the first wall 80 and the second wall 82.

Mindestens ein Wellenstummel ist verschieblich ausgeführt. Bei dem gezeigten Ausführungsbeispiel ist der zweite Wellenstummel 96 in einer Richtung 100, welche parallel zur Drehachse 78 ist, verschieblich ausgebildet.At least one shaft stub is designed to be movable. In the exemplary embodiment shown, the second shaft stub 96 is designed to be displaceable in a direction 100 which is parallel to the axis of rotation 78.

Der zweite Wellenstummel 96 ist dabei federbelastet; es ist eine Federeinrichtung 102 vorgesehen, welche in einer Ausnehmung 104 im Bereich der zweiten Stirnseite 92 des Saugkopfs 76 angeordnet ist. In der Ausnehmung 104 ist der zweite Wellenstummel 96 in der Richtung 100 verschieblich, wobei sich die Federeinrichtung 102 an einer Rückseite 106 des zweiten Wellenstummels 96 und einem Boden 108 der Ausnehmung 104 abstützt. Die Federeinrichtung 102 drückt den zweiten Wellenstummel 96 von dem Boden 108 weg.The second stub shaft 96 is spring-loaded; a spring device 102 is provided, which is arranged in a recess 104 in the region of the second end face 92 of the suction head 76. The second stub shaft 96 is displaceable in the direction 100 in the recess 104, the spring device 102 being supported on a rear side 106 of the second stub shaft 96 and a bottom 108 of the recess 104. The spring device 102 presses the second shaft stub 96 away from the base 108.

An dem zweiten Wellenstummel 96 ist ein Anlageelement 110 angeordnet, welches beispielsweise scheibenförmig ist. Eine Decke 112 für die Ausnehmung 104 bildet eine Anlagefläche für das Anlageelement 110 aus, welches die Wegverschiebung des zweiten Wellenstummels 96 von dem Boden 108 weg begrenzt. Das Anlageelement 110 und die Decke 112 sind so dimensioniert, dass, wenn das Anlageelement 110 an der Decke 112 anliegt, der zweite Wellenstummel 96 in der Aufnahme 86 so positioniert ist, dass der Saugkopf 76 in dem Gehäuseinnenraum 74 drehbar an der ersten Wand 80 und der zweiten Wand 82 gehalten ist.A contact element 110, which is, for example, disk-shaped, is arranged on the second shaft stub 96. A cover 112 for the recess 104 forms a contact surface for the contact element 110, which limits the displacement of the second shaft stub 96 away from the bottom 108. The contact element 110 and the ceiling 112 are dimensioned such that, when the contact element 110 lies against the ceiling 112, the second shaft stub 96 is positioned in the receptacle 86 in such a way that the suction head 76 is rotatable in the housing interior 74 on the first wall 80 and the second wall 82 is held.

Um den zweiten Wellenstummel 96 aus der Aufnahme 86 herauszuführen, muss der zweite Wellenstummel 96 in Richtung auf den ersten Wellenstummel 94 entgegen der Federkraft der Federeinrichtung 102 verschoben werden. Dadurch kann der zweite Wellenstummel 96 aus der Aufnahme 86 austauchen. Es ist dann möglich, den Saugkopf 76 als Ganzes von dem Gehäuse 48 abzunehmen.In order to guide the second stub shaft 96 out of the receptacle 86, the second stub shaft 96 must be displaced in the direction of the first stub shaft 94 against the spring force of the spring device 102. As a result, the second shaft stub 96 can emerge from the receptacle 86. It is then possible to remove the suction head 76 as a whole from the housing 48.

Die Aufnahme 86 (und vorteilhafterweise auch die Aufnahme 84) ist als durchgehende Ausnehmung ausgebildet. Ein Bediener kann dann von außen den zweiten Wellenstummel 96 aus der Aufnahme 86 hinausdrücken, um eine Entnahme des Saugkopfs 76 zu ermöglichen.The receptacle 86 (and advantageously also the receptacle 84) is designed as a continuous recess. An operator can then press the second shaft stub 96 out of the receptacle 86 from the outside in order to enable the suction head 76 to be removed.

An dem Saugkopf 76 ist eine Führungskufeneinrichtung 114 angeordnet, durch welche eine vergrößerte Auflagefläche für die Auflage des Saugkopfs 76 an der zu reinigenden Fläche 64 bewirkt wird.A guide runner device 114 is arranged on the suction head 76, by means of which an enlarged contact surface for the contact of the suction head 76 on the surface 64 to be cleaned is effected.

Bei einem Ausführungsbeispiel umfasst die Führungskufeneinrichtung 114 eine erste Führungskufe 116, welche im Bereich der ersten Stirnseite 90 angeordnet ist. Es ist ferner eine beabstandete zweite Führungskufe 118 vorgesehen, welche im Bereich der zweiten Stirnseite 92 angeordnet ist. Zwischen der ersten Führungskufe 116 und der zweiten Führungskufe 118 liegt ein Freiraum.In one embodiment, the guide runner device 114 comprises a first guide runner 116 which is arranged in the region of the first end face 90. Furthermore, a spaced-apart second guide runner 118 is provided, which is arranged in the region of the second end face 92. There is a free space between the first guide runner 116 and the second guide runner 118.

Die erste Führungskufe 116 und die zweite Führungskufe 118 sind parallel zueinander ausgerichtet. Sie erstrecken sich jeweils in eine Richtung quer zu der Drehachse 78.The first guide runner 116 and the second guide runner 118 are aligned parallel to one another. They each extend in a direction transverse to the axis of rotation 78.

Die erste Führungskufe 116 und die zweite Führungskufe 118 sind der Unterseite des Halters 52 zugewandt und erstrecken sich in den Hinterraum 70. Dadurch wird ein Anstoßen der Führungskufen 116, 118 an eine Querfläche zu der zu reinigenden Fläche 64 verhindert, wenn der Saugkörper 56 in Gegenrichtung zu der Richtung 72 auf diese Querfläche zubewegt wird.The first guide runner 116 and the second guide runner 118 face the underside of the holder 52 and extend into the rear space 70. This prevents the guide runners 116, 118 from hitting a transverse surface to the surface 64 to be cleaned when the suction body 56 is in the opposite direction towards the direction 72 is moved towards this transverse surface.

Eine Unterseite 120 der Führungskufeneinrichtung 114 ist insbesondere eben ausgebildet beziehungsweise bildet eine ebene Einhüllendenfläche.An underside 120 of the guide runner device 114 is in particular designed to be flat or forms a flat envelope surface.

Bei einem Ausführungsbeispiel sind an der Führungskufeneinrichtung 114 Rollen 122 angeordnet (in Figur 4 angedeutet). Eine entsprechende Saugdüsenvorrichtung mit solchen Rollen 122 ist insbesondere zur Reinigung von Hartböden geeignet.In one embodiment, rollers 122 are arranged on the guide runner device 114 (in Figure 4 indicated). A corresponding suction nozzle device with such rollers 122 is particularly suitable for cleaning hard floors.

Bei einer Saugdüsenvorrichtung, welche zur Reinigung von textilen Materialien und insbesondere zur Reinigung von Teppichböden verwendet wird, ist die Führungskufeneinrichtung 114 als Gleitführung ohne Rollen 122 ausgebildet.In a suction nozzle device which is used for cleaning textile materials and in particular for cleaning carpets, the guide runner device 114 is designed as a sliding guide without rollers 122.

In dem Gehäuseinnenraum 74 des Gehäuses 48 ist ein Gleitlager 124 für den Saugkopf 76 angeordnet. Dieses Gleitlager 124 umfasst eine Gleitfläche 126 mit einer (Hohl-)Zylinderkontur, welches angepasst ist an eine entsprechende Zylinderkontur des Saugkopfs 76. Der Saugkopf 76 liegt an der Gleitfläche 126 an. Durch das Gleitlager 124 mit Anlage einer Außenkontur des Saugkopfs 76 an der Gleitfläche 126 ist eine Gleitdichtung gebildet.A slide bearing 124 for the suction head 76 is arranged in the housing interior 74 of the housing 48. This sliding bearing 124 comprises a sliding surface 126 with a (hollow) cylinder contour which is adapted to a corresponding cylinder contour of the suction head 76. The suction head 76 rests on the sliding surface 126. A sliding seal is formed by the sliding bearing 124 with an outer contour of the suction head 76 resting on the sliding surface 126.

Die Gleitfläche 126 umgibt ein Rohrelement 128, welches in dem Gehäuseinnenraum 74 angeordnet ist. Das Rohrelement 128 hat einen Saugraum 130, welcher in fluidwirksamer Verbindung mit dem Anschluss 28 steht. Der Saugraum 130 ist über ein Rohr 132 mit dem Rohrstück 50 verbunden. Das Rohr 132 ist dabei an einem Übergangsbereich 134 vom Saugkörper 46 der Saugdüse 42 zu dem Rohrstück 50 angeordnet.The sliding surface 126 surrounds a tubular element 128 which is arranged in the housing interior 74. The pipe element 128 has a suction space 130 which is in fluid communication with the connection 28. The suction chamber 130 is connected to the pipe section 50 via a pipe 132. The pipe 132 is arranged in a transition region 134 from the suction body 46 of the suction nozzle 42 to the pipe section 50.

An dem Saugkopf 76 ist (mindestens) eine Einsaugöffnung 136 angeordnet. Die Einsaugöffnung 136 ist eine Mündung eines (oder mehrerer) Saugkanäle 138, welche durch den Körper 88 durchgehen und auf einer der Einsaugöffnung 136 abgewandten Seite in (mindestens) einer Auslassöffnung 140 münden. Die Auslassöffnung 140 ist unabhängig von der Drehstellung des Saugkopfs 76 in dem Saugraum 130 positioniert.(At least) one suction opening 136 is arranged on the suction head 76. The suction opening 136 is an opening of one (or more) suction channels 138, which pass through the body 88 and open into (at least) one outlet opening 140 on a side facing away from the suction opening 136. The outlet opening 140 is positioned in the suction chamber 130 independently of the rotational position of the suction head 76.

Bei Betrieb der Saugdüsenvorrichtung 18 ist die Einsaugöffnung 136 direkt der zu reinigenden Fläche 64 zugewandt.When the suction nozzle device 18 is in operation, the suction opening 136 faces directly towards the surface 64 to be cleaned.

An dem Körper 88 des Saugkopfs 76 ist ein Eintauchelement 142 gebildet, welches in dem Saugraum 130 eingetaucht ist. An dem Eintauchelement 142 liegt die Auslassöffnung 140. Das Eintauchelement 142 ist in dem Saugraum 130 drehbar, wobei das Eintauchelement 142 an dem Rohrelement 128 anliegt; dadurch ist eine Gleitdichtung zwischen dem Eintauchelement 142 und dem Rohrelement 128 gebildet.An immersion element 142, which is immersed in the suction space 130, is formed on the body 88 of the suction head 76. On the immersion element 142 is the outlet opening 140. The immersion element 142 is rotatable in the suction chamber 130, the immersion element 142 resting against the pipe element 128; as a result, a sliding seal is formed between the immersion element 142 and the tubular element 128.

Für eine Drehbarkeit (Schwenkbarkeit) des Eintauchelements 142 in dem Rohrelement 128 weist das Eintauchelement 142 einen Stirnkopf 144 auf, welcher abgerundet ist.For rotatability (pivotability) of the immersion element 142 in the tubular element 128, the immersion element 142 has an end head 144 which is rounded.

Bei einem Ausführungsbeispiel ist die Einsaugöffnung 136 als Schlitz ausgebildet, welcher sich insbesondere über näherungsweise die gesamte Länge des Saugkopfs 76 zwischen dem ersten Wellenstummel 94 und dem zweiten Wellenstummel 96 erstreckt. Dadurch wird eine große Mündungsfläche zum Einsaugen bereitgestellt.In one embodiment, the suction opening 136 is designed as a slot which extends in particular over approximately the entire length of the suction head 76 between the first stub shaft 94 and the second stub shaft 96. This provides a large opening area for suction.

Der Saugkanal 138 an der Einsaugöffnung 136 weist bei einem Ausführungsbeispiel eine geringere Länge als die Einsaugöffnung 136 auf. Insbesondere entspricht eine Länge der Auslassöffnung 140 mindestens näherungsweise einer entsprechenden Länge des Saugraums 130.In one embodiment, the suction channel 138 at the suction opening 136 has a shorter length than the suction opening 136. In particular, a length of the outlet opening 140 corresponds at least approximately to a corresponding length of the suction chamber 130.

Die Lage der Drehachse 78 relativ zu der Saugdüse 42 ist unabhängig von der Schwenkstellung des Saugkopfs 76. Dadurch ergibt sich unabhängig von der Drehposition (Schwenkposition) des Saugkopfs 76 das gleiche Sprühbild.The position of the axis of rotation 78 relative to the suction nozzle 42 is independent of the pivoting position of the suction head 76. This results in the same spray pattern regardless of the rotational position (pivoting position) of the suction head 76.

Die Saugdüsenvorrichtung 18 funktioniert wie folgt:
Die Saugdüsenvorrichtung 18 ist bei einem Betrieb des Reinigungsgeräts 10 an dieses angeschlossen. Der Anschluss 28 zur Unterdruckbeaufschlagung ist an den Sauganschluss 16 angeschlossen und der Sprühanschluss 56 ist an den Bereitstellungsanschluss 20 angeschlossen.The suction nozzle device 18 functions as follows:
The suction nozzle device 18 is connected to the cleaning device 10 when it is in operation. The connection 28 for applying negative pressure is connected to the suction connection 16 and the spray connection 56 is connected to the supply connection 20.

Die Gebläseeinrichtung 14 erzeugt einen Unterdruck-Luftstrom (Saugluftstrom), welcher an der Einsaugöffnung 136 ansteht. Über den Bereitstellungsanschluss 20 wird der Sprühdüse 54 Sprühflüssigkeit bereitgestellt.The blower device 14 generates a negative pressure air flow (suction air flow) which is present at the suction opening 136. Spray liquid is provided to the spray nozzle 54 via the supply connection 20.

Beim Reinigungsbetrieb liegt der Saugkopf 76 auf der zu reinigenden Fläche 64 auf. Zusätzlich liegt die Führungskufeneinrichtung 114 auf der zu reinigenden Fläche 64 auf.During the cleaning operation, the suction head 76 rests on the surface 64 to be cleaned. In addition, the guide runner device 114 rests on the surface 64 to be cleaned.

Durch den drehbaren Saugkopf 76 ist der spitze Winkel 62 an die Größe eines Bedieners anpassbar, so dass sich unabhängig von der Größe des Bedieners eine komfortable Arbeitsposition ergibt.With the rotatable suction head 76, the acute angle 62 can be adapted to the size of an operator, so that a comfortable working position is obtained regardless of the operator's size.

Der Saugkopf 76 passt sich automatisch an, so dass die Einsaugöffnung 136 zum entsprechenden Einsaugen positioniert ist.The suction head 76 adjusts itself automatically so that the suction opening 136 is positioned for the corresponding suction.

Es ergibt sich dabei unabhängig von dem Winkel 62 an der zu reinigenden Fläche 64 in der Nähe des Saugkopfs 76 das gleiche Sprühbild; die Drehachse 78 liegt in einer festen Position zu der Sprühdüse 54.This results in the same spray pattern regardless of the angle 62 on the surface 64 to be cleaned in the vicinity of the suction head 76; the axis of rotation 78 lies in a fixed position relative to the spray nozzle 54.

Der Saugkörper 46 definiert einen ersten Anschlag 146 (Figur 4) und einen zweiten Anschlag 148 für die Drehbarkeit des Saugkopfs 76. Zwischen dem ersten Anschlag 146 und dem zweiten Anschlag 148 ist der Saugkopf 76 stufenlos drehbar und damit der Winkel 62 einstellbar.The absorbent body 46 defines a first stop 146 ( Figure 4 ) and a second stop 148 for the rotatability of the suction head 76. Between the first stop 146 and the second stop 148, the suction head 76 can be rotated steplessly and the angle 62 is thus adjustable.

Der Saugkopf 76 schlägt an dem ersten Anschlag 146 insbesondere über die Führungskufeneinrichtung 114 an.The suction head 76 strikes the first stop 146, in particular via the guide runner device 114.

Zum Anschlag an dem zweiten Anschlag 148, welcher insbesondere an einer Stirnseite des Gleitlagers 124 gebildet ist, ist an dem Körper 88 eine Anschlagleiste 150 ausgebildet.For stopping against the second stop 148, which is formed in particular on an end face of the slide bearing 124, a stop bar 150 is formed on the body 88.

Durch die freie Drehbarkeit des Saugkopfs 76 zwischen dem ersten Anschlag 146 und dem zweiten Anschlag 148 kann ein Bediener auch die Winkelposition der Saugdüsenvorrichtung 18 anpassen, um bestimmte Flächen zu reinigen.Because the suction head 76 can rotate freely between the first stop 146 and the second stop 148, an operator can also adjust the angular position of the suction nozzle device 18 in order to clean certain surfaces.

Die Führungskufeneinrichtung 114 weist in den Hinterraum 70. Dadurch lässt sich der Saugkörper 46 an einer in den Vorderraum 68 weisenden Vorderseite 152 mindestens näherungsweise eben beziehungsweise mit ebener Einhüllendenfläche ausbilden. Dadurch kann der Saugkörper 46 dicht an eine Querwand zu der zu reinigenden Fläche 64 geschoben werden, wobei insbesondere die Führungskufeneinrichtung 114 dieses Anschieben beziehungsweise Anliegen nicht behindert.The guide runner device 114 points into the rear space 70. As a result, the absorbent body 46 can be embodied on a front side 152 pointing into the front space 68 at least approximately flat or with a flat envelope surface. As a result, the absorbent body 46 can be pushed tightly against a transverse wall to the surface 64 to be cleaned, the guide runner device 114 in particular not hindering this pushing or contact.

Wenn beispielsweise eine Sprühextraktionsreinigung eines textilen Materials wie beispielsweise eines Teppichbodens durchgeführt wird, dann wird der Saugkopf 76 in der Richtung 72 bewegt, das heißt er wird in diese Richtung 72 gezogen. Ein zu reinigender Flächenbereich wird dann zuerst mit Sprühflüssigkeit besprüht und anschließend fährt der Saugkopf 76 mit der Einsaugöffnung 136 über den besprühten Flächenbereich und saugt überschüssige Flüssigkeit (mit gelöstem Schmutz) ein.If, for example, a textile material such as a carpet floor is carried out by spray extraction, then the suction head 76 is moved in the direction 72, that is to say it is pulled in this direction 72. A surface area to be cleaned is then first sprayed with spray liquid and then the suction head 76 with the suction opening 136 moves over the sprayed surface area and sucks in excess liquid (with loosened dirt).

Der Saugkopf 76 ist zwischen der ersten Wand 80 und der zweiten Wand 82 in dem Gehäuseinnenraum 74 positioniert. Er ist dadurch geschützt angeordnet und ein entsprechendes Drehlager 98 lässt sich auf einfache Weise über die Wellenstummel 94, 96 ausbilden.The suction head 76 is positioned between the first wall 80 and the second wall 82 in the housing interior 74. It is arranged in a protected manner and a corresponding rotary bearing 98 can be formed in a simple manner via the stub shaft 94, 96.

Die (mindestens eine) Auslassöffnung 140 mündet unabhängig von der Drehstellung des Saugkopfs 76 auf die gleiche Weise in den Saugraum 130. Es lassen sich dadurch Querschnittssprünge mit einer negativen Strömungsbeeinflussung verhindern und es wird ein optimiertes Einsaugergebnis erhalten.The (at least one) outlet opening 140 opens into the suction chamber 130 in the same way regardless of the rotational position of the suction head 76. This prevents cross-sectional jumps with a negative flow influence and an optimized suction result is obtained.

Der Saugkopf 76 lässt sich durch die Ausbildung des Drehlagers 98 mit mindestens einem federbelasteten Wellenstummel 96 auf einfache Weise von dem Saugkörper 46 zur Reinigung abnehmen.The suction head 76 can be easily removed from the suction body 46 for cleaning due to the design of the rotary bearing 98 with at least one spring-loaded shaft stub 96.

Es ist dadurch auch möglich, die Saugdüsenvorrichtung 18 auf einfache Weise durch Umrüstung des Saugkopfs 76 an die zu reinigende Fläche 64 anzupassen.It is thereby also possible to adapt the suction nozzle device 18 to the surface 64 to be cleaned in a simple manner by converting the suction head 76.

Bei einem Ausführungsbeispiel ist ein Satz von unterschiedlichen Saugköpfen 76 vorgesehen, um ein optimiertes Reinigungsergebnis für unterschiedliche Arten von zu reinigenden Flächen 64 zu erhalten.In one embodiment, a set of different suction heads 76 is provided in order to obtain an optimized cleaning result for different types of surfaces 64 to be cleaned.

Insbesondere umfasst der Satz an Saugköpfen 76 einen Saugkopf zur Reinigung von Hartböden. Ein solcher Saugkopf weist insbesondere Rollen 122 an der Führungskufeneinrichtung 114 auf. Ferner können Lippen aus einem elastischen Material wie beispielsweise Gummilippen vorgesehen sein, welche sich in Längsrichtung der Einsaugöffnung 136 erstrecken, wobei die Einsaugöffnung 136 zwischen solchen Lippen liegt.In particular, the set of suction heads 76 includes a suction head for cleaning hard floors. Such a suction head has, in particular, rollers 122 on the guide runner device 114. Furthermore, lips made of an elastic material, such as for example rubber lips, can be provided which extend in the longitudinal direction of the suction opening 136, the suction opening 136 lying between such lips.

Es ist ferner ein Saugkopf 76 für die Reinigung von textilen Materialien wie Teppichböden vorgesehen. Bei diesem Ausführungsbeispiel ist die Führungskufeneinrichtung 114 als reine Gleitführung ausgebildet, welche über das textile Material gleiten kann. Der Saugkopf 76 ist ferner zur Gleitführung an der zu reinigenden Fläche 64 aus textilem Material ausgebildet, ohne dass Gummilippen oder dergleichen vorgesehen sind.A suction head 76 is also provided for cleaning textile materials such as carpets. In this exemplary embodiment, the guide runner device 114 is designed as a pure sliding guide which can slide over the textile material. The suction head 76 is also designed for sliding guidance on the surface 64 to be cleaned made of textile material, without rubber lips or the like being provided.

Die Saugdüse 42 der Saugdüsenvorrichtung 18 ist bei der erfindungsgemäßen Lösung kompakt aufgebaut. Der Saugkopf 76 liegt in dem Gehäuseinnenraum 74. Er ist dadurch vor Beschädigung geschützt und weniger empfindlich gegen Verunreinigungen.The suction nozzle 42 of the suction nozzle device 18 is compact in the solution according to the invention. The suction head 76 lies in the housing interior 74. It is thereby protected from damage and is less sensitive to contamination.

Der Saugkopf 76 kann auf leichte Weise entfernt werden und wieder eingesetzt werden. Dadurch ist zum einen eine leichte Reinigung des Saugkopfs 76 möglich und zum anderen kann die Saugdüsenvorrichtung 18 und damit auch das Reinigungsgerät 10 auf einfache Weise an die Art der zu reinigenden Fläche 64 wie beispielsweise Hartboden oder textiles Material angepasst werden.The suction head 76 can be easily removed and reinserted. On the one hand, this enables the suction head 76 to be cleaned easily possible and on the other hand the suction nozzle device 18 and thus also the cleaning device 10 can be adapted in a simple manner to the type of surface 64 to be cleaned, such as hard floor or textile material.

Durch die Positionierung des Saugkopfs 76 in dem Gehäuseinnenraum 74, das heißt durch eine Innen-Drehlagerung des Saugkopfs 76 lassen sich große Querschnittssprünge in dem Fluidweg ausgehend von der Einsaugöffnung 136 bei jeder Drehstellung des Saugkopfs 76 vermeiden und es ergibt sich dadurch eine effektive Saugwirkung.By positioning the suction head 76 in the housing interior 74, that is to say by means of an internal rotary bearing of the suction head 76, large cross-sectional jumps in the fluid path starting from the suction opening 136 can be avoided in every rotary position of the suction head 76, and this results in an effective suction effect.
