Aus der Druckschrift
Demnach sind die vorhandenen Lösungen nicht ganz ausgereift und bieten noch ein weites Betätigungsfeld für Verbesserungen und Innovationen.Therefore, the existing solutions are not fully developed and still offer a wide field of activity for improvements and innovations.
Der Erfindung liegt die Aufgabe zu Grunde, einen verbesserten Schmutzbehälter für einen Handstaubsauger bereitzustellen, bei dem ein verbessertes Einströmverhalten erzielt wird und ein benutzerfreundliches Handhaben und ein flexibler Einsatz möglich sind. Darüber hinaus soll der Schmutzbehälter einfach, robust und kostengünstig herzustellen sein.The invention has for its object to provide an improved dirt container for a hand vacuum cleaner, in which an improved Einströmverhalten is achieved and a user-friendly handling and flexible use are possible. In addition, the dirt container should be simple, robust and inexpensive to manufacture.
Die Lösung der gestellten Aufgabe gelingt mit einem Schmutzbehälter für einen Staubsauger mit den Merkmalen des Anspruchs 1 sowie einem damit versehenen Handstaubsauger mit den Merkmalen des Anspruchs 11.The solution of the problem is achieved with a dirt container for a vacuum cleaner with the features of
Erfindungsgemäß ist dazu ein Schmutzbehälter für einen Handstaubsauger vorgesehen, wobei der Schmutzbehälter über eine Einlassöffnung mit einem Einlassstutzen zur Aufnahme angesaugter verschmutzter Luft verbindbar ist und wobei der Schmutzbehälter zusammen mit einem darin aufnehmbaren Abscheider zum Abscheiden von Schmutz aus der verschmutzten Luft eine erste Einheit bildet, und wobei der Schmutzbehälter beziehungsweise die erst Einheit ein erstes Kopplungselement aufweist, das mit einem dazu korrespondierenden zweiten Kopplungselement einer zweiten Einheit zur Bildung einer Verbindungsvorrichtung koppelbar ist, wobei die zweite Einheit eine Motor-Gebläse-Einheit zum Erzeugen eines Luftstroms und einen Energiespeicher zum Antreiben der Motor-Gebläse-Einheit umfasst. Ein solcher Schmutzbehälter ist besonders flexibel einsetzbar, da in ihm Abscheider unterschiedlicher Art anordenbar sind und der Schmutzbehälter mit unterschiedlichen Einlassstutzen ausgerüstet werden kann. Darüber hinaus lässt sich die mittels des Schmutzbehälters gebildete Einheit nicht nur zur Aufnahme angesaugter schmutziger Luft verwenden, sondern sie ermöglicht darüber hinaus auch das Durchleiten eines Blas-Luftstroms, was in manchen Fällen besonders günstig ist, um beispielsweise Schmutz in unzugänglichen Ecken heraus zu blasen oder den Handstaubsauger zum Aufblasen unterschiedlicher aufblasbarer Vorrichtungen zu nutzen. Mit anderen Worten gesagt, lässt sich die Richtung des Luftstroms umkehren. Eine solche Umkehrung ist natürlich nur dann möglich, wenn im Schmutzbehälter keine Abscheideeinheit untergebracht bzw. angeordnet ist. Da die erste Einheit, die einen Schmutzbehälter, einen Abscheider und einen Einlassstutzen umfasst, besonders kompakt und leicht aufgebaut ist, ist Ihre Handhabung auch besonders benutzerfreundlich, zumal sie getrennt vom Handstaubsauger, beispielsweise über den frontal angeordneten Einlassstutzen getragen und einfach über einen Mülleimer ausgeleert werden kann. Ferner ist der Schmutzbehälter besonders flexibel einsetzbar, da in ihm je nach Bedarf des Benutzers unterschiedliche Abscheider bzw. Abscheidesysteme angeordnet werden können. Dasselbe trifft für die damit aufgebaute erste Einheit zu, wobei ein modularer Zusammenbau eines Handstaubsaugers in Abhängigkeit der Bedürfnisse des Benutzers denkbar ist.According to the invention, a dirt container for a hand vacuum cleaner is provided, wherein the dirt container via an inlet opening with an inlet nozzle for receiving sucked polluted air is connectable and wherein the dirt container forms a first unit together with a recordable therein for separating dirt from the polluted air, and the dirt container or the first unit has a first coupling element, which can be coupled to a second coupling element of a second unit forming a connecting device, the second unit comprising a motor-blower unit for generating an air flow and an energy store for driving the motor-blower Unit includes. Such a dirt container can be used particularly flexibly, since separators of different types can be arranged in it and the dirt container can be equipped with different inlet nozzles. In addition, the unit formed by the dirt container can not only be used to pick up sucked dirty air, but it also allows the passage of a blast air flow, which is particularly favorable in some cases, for example, to blow out dirt in inaccessible corners or to use the hand vacuum cleaner to inflate different inflatable devices. In other words, the direction of the airflow can be reversed. Of course, such a reversal is only possible if no separation unit is housed or arranged in the dirt container. Since the first unit, which includes a dirt container, a separator and an inlet nozzle, is particularly compact and lightweight, your handling is also very user-friendly, especially since they are carried separately from the vacuum cleaner, for example via the frontally arranged inlet nozzle and simply emptied through a trash can can. Furthermore, the dirt container is particularly flexible, since different separators or separation systems can be arranged in it according to the needs of the user. The same applies to the thus constructed first unit, wherein a modular assembly of a hand vacuum cleaner is conceivable depending on the needs of the user.
So kann bei einer vorteilhaften Alternative ein Abscheider vorgesehen werden, der nach dem Fliehkraftprinzip arbeitet. Solche Abscheider ermöglichen es, eine nahezu gleich bleibende Saugleistung des Handstaubsaugers aufrecht zu erhalten, unabhängig von dem bereits in dem Schmutzbehälter aufgenommenen Staub bzw. Schmutz. Staubsauger beziehungsweise Abscheider, die nach dem Fliehkraftprinzip arbeiten, nutzen die Zentrifugalkräfte zur Trennung von Staub und Schmutz aus der angesaugten Luft. Bei einer Staubabscheideeinheit des Staubsaugers wird die verschmutzte Luft als Träger der abzuscheidenden Partikel - Schmutz und Staub - durch deren eigene Strömungsgeschwindigkeit und eine entsprechende konstruktive Gestaltung der Staubabscheideeinheit in eine Drehbewegung versetzt. Die Stofftrennung erfolgt im Fliehkraft-Abscheider durch die auf den Schmutz und Staub wirkenden Zentrifugalkräfte beziehungsweise Fliehkräfte. Gängige Bezeichnungen für Staubsauger mit Abscheidern, die eingerichtet sind, nach dem Fliehkraftprinzip bei einer Dreh- und/oder Schraubbewegung des Luftstroms zu arbeiten, sind Fliehkraftabscheider, Zyklonstaubsauger oder Drallabscheider.Thus, in an advantageous alternative, a separator may be provided, which operates on the principle of centrifugal force. Such separators make it possible to maintain a nearly constant suction capacity of the hand vacuum cleaner, regardless of the dust or dirt already received in the dirt container. Vacuum cleaners or separators, which operate on the centrifugal force principle, use the centrifugal forces to separate dust and dirt from the intake air. In a Staubabscheideeinheit the vacuum cleaner, the polluted air as a carrier of the particles to be separated - dirt and dust - by their own flow velocity and a corresponding structural design of the Staubabscheideeinheit offset in a rotary motion. The material separation takes place in the centrifugal separator by the centrifugal forces or centrifugal forces acting on the dirt and dust. Common names for vacuum cleaners with separators, which are designed to operate according to the principle of centrifugal force during a rotary and / or screw movement of the air flow, are centrifugal separators, cyclone vacuums or swirl separators.
Bei einer weiteren Alternative ist der Abscheider ein Staubfilterbeutel. Staubfilterbeutel eignen sich insbesondere zur Aufnahme von Schmutz und Staub einer besonders kleinen Körnung und sind daher besonders für Benutzer mit Staub-Allergien geeignet. Darüber hinaus weist ein Handstaubsauger mit einem Staubfilterbeutel als Abscheider eine reduzierte Geräuschemission gegenüber einem herkömmlichen Handstaubsauger auf, der einen Abscheider verwendet, der nach dem Fliehkraftprinzip arbeitet.In another alternative, the separator is a dust filter bag. Dust filter bags are particularly suitable for receiving dirt and dust of a particularly small grain size and are therefore particularly suitable for users with dust allergies. In addition, a hand vacuum cleaner with a dust filter bag as a separator on a reduced noise emission compared to a conventional hand vacuum cleaner using a separator, which operates on the principle of centrifugal force.
Bei einer weiteren Alternative ist der Abscheider ein Nassabscheider, wodurch der Handstaubsauger sogar zur Aufnahme und Reinigung feuchter Schmutzpartikel oder sogar Flüssigkeiten eingesetzt werden kann.In a further alternative, the separator is a wet scrubber, whereby the hand vacuum cleaner can even be used for receiving and cleaning moist dirt particles or even liquids.
Ein weiterer Aspekt der Erfindung betrifft einen Handstaubsauger umfassend eine erste Einheit gemäß einer der nachstehend beschriebenen Ausführungsformen mit einem Schmutzbehälter und einem darin aufnehmbaren Abscheider zum Abscheiden von Schmutz aus der verschmutzten Luft, wobei der Schmutzbehälter über eine Einlassöffnung mit einem Einlassstutzen zur Aufnahme angesaugter verschmutzter Luft verbindbar ist und eine an die erste Einheit koppelbare zweite Einheit wobei die erste Einheit ein erstes Kopplungselement aufweist, das mit einem dazu korrespondierenden zweiten Kopplungselement der zweiten Einheit zur Bildung einer Verbindungsvorrichtung koppelbar ist, wobei die zweite Einheit eine Motor-Gebläse-Einheit zum Erzeugen eines Luftstroms und einen Energiespeicher zum Antreiben der Motor-Gebläse-Einheit umfasst, und die gebildete Verbindungsvorrichtung eingerichtet ist, die erste Einheit und die damit verbindbare zweiten Einheit aus einer Verschlussstellung in eine Offenstellung oder Trennungsstellung gegeneinander zu verdrehen und umgekehrt. Die in den vorherstehenden Ausführungsformen des Schmutzbehälters beschriebenen Vorteile und Wirkungen sind ebenso für den Handstaubsauger zutreffend, der die erste Einheit bzw. den Schmutzbehälter umfasst.A further aspect of the invention relates to a hand vacuum cleaner comprising a first unit according to one of the embodiments described below with a dirt container and a receptacle therein for removing dirt from the polluted air, the dirt container via an inlet opening with an inlet nozzle for receiving sucked polluted air connectable and a second unit which can be coupled to the first unit, wherein the first unit has a first coupling element that can be coupled to a second coupling element of the second unit forming a connecting device, the second unit comprising a motor-fan unit for generating an air flow and an energy storage for driving the motor-blower unit, and the formed connection device is configured to move the first unit and the second unit connectable therewith from a closed position to an open position ng or separation position to turn against each other and vice versa. The advantages and effects described in the foregoing embodiments of the dirt container are also applicable to the hand vacuum cleaner comprising the first unit and the dirt container, respectively.
Im Sinne der Erfindung ist mit einem Handstaubsauger ein Staubsauger zu verstehen, der ein geringes Gewicht und eine kompakte Bauweise aufweist und deswegen einhändig tragbar und bedienbar ist.For the purposes of the invention is to be understood with a hand vacuum cleaner, a vacuum cleaner, which has a low weight and a compact design and therefore one hand is portable and operable.
Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind Gegenstand der abhängigen Ansprüche. Die für den erfindungsgemäßen Schmutzbehälter zutreffenden Vorteile gelten gleichermaßen für einen damit versehenen und betriebenen Handstaubsauger.Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims. The advantages that apply to the dirt container according to the invention apply equally to a hand vacuum cleaner provided with it and operated.
Zweckmäßigerweise ist das zur Bildung der Verbindungsvorrichtung koppelbare erste Kopplungselement zerstörungsfrei an das korrespondierende zweite Kopplungselement koppelbar und/oder lösbar. Dadurch lassen sich die einzelnen Einheiten gesondert warten oder nach Bedarf austauschen oder aufbewahren. Darüber hinaus wird die Benutzung, beispielsweise das Entleeren des Schmutzbehälters, erheblich erleichtert, da der entkoppelte Schmutzbehälter alleine nicht so sperrig ist wie in dem gekoppelten Zustand.Conveniently, the first coupling element which can be coupled to form the connecting device can be coupled to the corresponding second coupling element in a non-destructive manner and / or detachably. This allows the individual units to be maintained separately or replaced or stored as needed. In addition, the use, for example, the emptying of the dirt container, greatly facilitated because the decoupled dirt container alone is not as bulky as in the coupled state.
Vorteilhafterweise ist das zur Bildung der Verbindungsvorrichtung koppelbare erste Kopplungselement eingerichtet, mit dem korrespondierenden zweiten Kopplungselement eine gelenkige Verbindung zu bilden, mit dem die erste Einheit gegen die zweite Einheit aus einer Offenstellung oder Trennungsstellung in eine Verschlussstellung drehbar ist und umgekehrt. Dieses ermöglicht dem Benutzer festzustellen, wie voll ein Schmutzbehälter oder ein im Schmutzbehälter angeordneter Staubfilterbeutel ist, ohne den Handstaubsauger gleich in mehrere Teile zerlegen zu müssen.Advantageously, the first coupling element which can be coupled to form the connecting device is designed to form an articulated connection with the corresponding second coupling element, with which the first unit can be rotated against the second unit from an open or disconnected position into a closed position and vice versa. This allows the user to determine how full a dirt container or dust filter bag placed in the dirt container is, without having to disassemble the hand vacuum cleaner into several parts.
Gemäß einer vorteilhaften Ausführungsform des Schmutzbehälters umfasst das zur Bildung der Verbindungsvorrichtung koppelbare erste Kopplungselement eine Schale oder einen Zapfen. Eine Achse des Zapfens definiert dabei die Schwenkachse, um die die erste Einheit gegen die zweite Einheit drehbar gelagert ist. Damit kann ein besonders einfaches und robustes Gelenk gebildet werden, dass ein leichtes Schwenken und Trennen des Schmutzbehälters von der zweiten Einheit des Handstaubsaugers ermöglicht. Weiter ermöglicht ein solches Gelenk ein einfaches und schnelles Zusammenfügen bzw. Trennung der ersten und der zweiten Einheit. Weiter kann dieses Gelenk im unteren Bereich des Schmutzbehälters oder in der Nähe des Bodens angeordnet sein. Damit kann ein einfaches intuitives Koppeln der beiden Kopplungselemente ermöglicht werden.According to an advantageous embodiment of the dirt container, the first coupling element, which can be coupled to form the connecting device, comprises a shell or a journal. An axis of the pin defines the pivot axis about which the first unit is rotatably mounted against the second unit. Thus, a particularly simple and robust joint can be formed, that a slight pivoting and separating the dirt container from the second unit of the hand vacuum cleaner allows. Furthermore, such a joint allows a simple and quick assembly or separation of the first and the second unit. Furthermore, this joint can be arranged in the lower region of the dirt container or in the vicinity of the bottom. Thus, a simple intuitive coupling of the two coupling elements can be made possible.
Bei einer besonders vorteilhaften Ausführungsform des Schmutzbehälters ist das zur Bildung der Verbindungsvorrichtung koppelbare erste Kopplungselement eingerichtet, mit dem korrespondierenden zweiten Kopplungselement einen Bajonettverschluss zu bilden, mit dem die erste Einheit gegen die zweite Einheit aus einer Offenstellung oder Trennungsstellung in eine Verschlussstellung drehbar ist und umgekehrt. Beispielsweise kann ein zylinderförmig ausgebildeter Schmutzbehälter aus einer Trennungsstellung, in der die erste und die zweite Einheit voneinander entkoppelt sind, in eine Offenstellung gebracht werden, in der die erste und die zweite Einheit miteinander gekoppelt sind Dabei kann beispielsweise eine zylinderförmige erste Einheit in eine dazu korrespondierende aufnehmende Schale - halber Zylinder - der zweiten Einheit eingebracht und gegen diese in eine feste Position - Verschlussstellung - verdreht werden.In a particularly advantageous embodiment of the dirt container which can be coupled to form the connecting device first coupling element is adapted to form a bayonet with the corresponding second coupling element with which the first unit is rotatable against the second unit from an open position or separation position into a closed position and vice versa. For example, a cylinder-shaped dirt container from a separation position in which the first and second units are decoupled from each other, be brought into an open position in which the first and the second unit are coupled to each other Here, for example, a cylindrical first unit in a corresponding thereto receiving shell - half cylinder - the second unit introduced and against this in a fixed position - closed position - twisted.
Bei einer noch vorteilhafteren Ausführungsform weist der Schmutzbehälter der ersten Einheit eine Fixierungsvorrichtung auf, die eingerichtet ist, die erste Einheit an eine dazu korrespondierende Fixierungsvorrichtung der damit verbindbaren zweiten Einheit in einer Verschlussstellung zu fixieren und in einer Offenstellung zu lösen. Dadurch kann sichergestellt werden, dass die erste Einheit mit der zweiten Einheit fest verbunden werden kann und dadurch ein stabiler und zuverlässig einsetzbarer Handstaubsauger gebildet wird.In an even more advantageous embodiment, the dirt container of the first unit has a fixing device which is set up to fix the first unit to a corresponding fixing device of the second unit which can be connected thereto in a closed position and to release it in an open position. It can thereby be ensured that the first unit can be firmly connected to the second unit, thereby forming a stable and reliably usable hand vacuum cleaner.
Bei einer besonders kostengünstigen und wirksamen Ausführungsform der Fixierungsvorrichtung für den Schmutzbehälter umfasst die Fixierungsvorrichtung zumindest einen Rast- oder Schnappverschluss. Letzterer ist einfach herzustellen und zu beschaffen und bietet eine zuverlässige Fixierungsmöglichkeit.In a particularly inexpensive and effective embodiment of the fixation device for the dirt container, the fixing device comprises at least one latching or snap closure. The latter is easy to manufacture and procure and provides a reliable fixation option.
Im Sinne der Erfindung ist ein Schnappverschluss ein Verschluss, der durch Einrasten, Einschnappen fest schließt. Ferner wird darunter ein Verschluss verstanden, der im Allgemeinen nach Überwinden einer mechanischen Schwelle einrastet und dadurch eine Fixierung gewährleistet.For the purposes of the invention, a snap closure is a closure that closes tightly by snapping, snapping. Further, this is understood to mean a closure which generally engages after overcoming a mechanical threshold and thereby a Fixation guaranteed.
Gemäß einer besonders vorteilhaften Ausführungsform des Schmutzbehälters ist die Fixierungsvorrichtung in unmittelbarer/greifbarer Nähe der Einlassöffnung angeordnet. Da sich der an die Einlassöffnung des Schmutzbehälters anordenbare Einlassstutzen insbesondere dazu eignet, den Schmutzbehälter bzw. die erste Einheit zu greifen, ist es für den Benutzer auch möglich, die Fixierungsvorrichtung mit derselben Hand bzw. einhändig zu bedienen.According to a particularly advantageous embodiment of the dirt container, the fixing device is arranged in the immediate / tangible vicinity of the inlet opening. Since the inlet nozzle which can be arranged on the inlet opening of the dirt container is particularly suitable for gripping the dirt container or the first unit, it is also possible for the user to operate the fixing device with the same hand or with one hand.
Besonders vorteilhaft ist es, wenn der Schmutzbehälter zumindest teilweise eine zur zweiten Einheit komplementäre Form aufweist. Dadurch lässt sich beispielsweise ein Bajonettverschluss zwischen dem zylinderförmigen Schmutzbehälter, bzw. der ersten Einheit und einer dazu komplementären Schale mit halb-zylindrischer Form, besonders einfach herstellen. Darüber hinaus ist es durch die komplementäre Form der beiden Einheiten möglich, eine optimale Verbindungsposition der beiden Einheiten zueinander einzustellen, da die komplementären Formen einander automatisch gegenseitig ausrichten. Zur optimalen Ausrichtung der beiden Einheiten zueinander können Vorsprünge und dazu korrespondierende Ausnehmungen vorgesehen sein, die beim Ineinandergreifen die beiden Einheiten automatisch in einer richtigen VerbindungsPosition zueinander ausrichten.It is particularly advantageous if the dirt container at least partially has a shape complementary to the second unit. As a result, for example, a bayonet lock between the cylindrical dirt container, or the first unit and a complementary shell with semi-cylindrical shape, particularly easy to manufacture. Moreover, it is possible by the complementary shape of the two units to set an optimal connection position of the two units to each other, since the complementary shapes automatically align each other. For optimal alignment of the two units to each other projections and corresponding recesses may be provided, which automatically align the two units in a correct connection position to each other when meshing.
Zweckmäßigerweise ist der Energiespeicher zum Antreiben der Motor-Gebläse-Einheit der zweiten Einheit des Handstaubsaugers ein elektrischer Akkumulator. Elektrische Akkumulatoren sind an die erforderlichen räumlichen Bedürfnisse im Handstaubsauger leicht anpassbar, einfach herzustellen und zu beschaffen. Weiter kann der Akkumulator als ein wechselbarer Akkumulator ausgeführt sein, sodass mit einem weiteren Akkumulator die Laufzeit von dem Handstaubsauger verlängert werden kann.Conveniently, the energy storage for driving the motor-blower unit of the second unit of the hand vacuum cleaner is an electrical accumulator. Electric accumulators are easily adaptable to the required space requirements in the hand vacuum cleaner, easy to manufacture and procure. Next, the accumulator can be designed as a removable accumulator, so that the term can be extended by the hand vacuum cleaner with another accumulator.
Um eine nahezu gleich bleibende Saugleistung des Handstaubsaugers aufrecht zu erhalten, unabhängig von dem bereits in dem Schmutzbehälter aufgenommenen Staub bzw. Schmutz umfasst der Handstaubsauger bei einer besonders zweckmäßigen Ausführungsform einen Abscheider zum Abscheiden von Schmutz aus der verschmutzten Luft, wobei der Abscheider nach dem Fliehkraftprinzip funktioniert. Insbesondere ist die Achse des Fliehkraftabscheiders bei einer üblichen Betriebslage des Handstaubsaugers derart angeordnet, dass sich der Staub und Schmutz auf Grund der Gravitationskraft der Erde am Boden des Schmutzbehälters ansammeln kann.In order to maintain a nearly constant suction power of the hand vacuum cleaner, regardless of the dust or dirt already received in the dirt container comprises the hand vacuum cleaner in a particularly useful embodiment, a separator for separating dirt from the polluted air, the separator works on the principle of centrifugal force , In particular, the axis of the centrifugal separator in a conventional operating position of the hand vacuum cleaner arranged so that the dust and dirt can accumulate due to the gravitational force of the earth at the bottom of the dirt container.
Bei einer besonders bevorzugten Ausführungsform des Handstaubsaugers ist die Fixierungsvorrichtung des Schmutzbehälters bzw. der ersten Einheit eingerichtet, einhändig oder mittels eines Fingers einer Hand gelöst zu werden. Besonders bevorzugt handelt es sich dabei um den Finger derselben Hand, die den einhändig tragbaren Handstaubsauger auch bedient und trägt. Dabei weist der Schmutzbehälter eine Fixierungsvorrichtung auf, die eingerichtet ist, die erste Einheit an eine dazu korrespondierende Fixierungsvorrichtung der zweiten Einheit in einer Verschlussstellung zu fixieren und in einer Offenstellung zu lösen, wobei die Fixierungsvorrichtung eingerichtet ist, mittels eines Fingers derselben Hand gelöst zu werden, die die erste Einheit hält.In a particularly preferred embodiment of the hand vacuum cleaner, the fixing device of the dirt container or the first unit is set up to be released with one hand or by means of a finger of one hand. Particularly preferably, this is the finger of the same hand, which also operates and carries the hand-held vacuum cleaner with one hand. In this case, the dirt container on a fixing device which is adapted to fix the first unit to a corresponding thereto fixing device of the second unit in a closed position and to release in an open position, wherein the fixing device is adapted to be solved by a finger of the same hand, which holds the first unit.
Die vorliegenden Ausführungsformen der Erfindung tragen dazu bei, die Benutzerfreundlichkeit bei Handstaubsaugern wesentlich zu erhöhen. Durch die Möglichkeit der modularen Gestaltung der ersten Einheit, die einen Schmutzbehälter, einen Abscheider und einen dazu passenden Einlassstutzen umfasst, ist der damit versehen Handstaubsauger besonders vielseitig und flexibel einsetzbar.The present embodiments of the invention help to substantially increase the ease of use of handheld vacuum cleaners.
