Definitions
- the invention relates to a bagless vacuum cleaner with a dust container.
- Bagless vacuum cleaners are known per se. These work with a centrifugal separator and the outer housing of such centrifugal separator, sometimes referred to as a cyclone, acts as a dust container in the bagless vacuum cleaner. In this dust container, the absorbed dust is collected to a large extent. During operation, however, pollute the inner surfaces of the dust container, in particular by there precipitated fine dust.
- Such bagless vacuum cleaners are thus capable of improvement insofar as a transparent dust container in the course of operation sometimes due to sucked up dust, especially fine dust, an unhygienic appearance receives when the dust is reflected on the inner surfaces of the dust container. Conversely, the dust container but also not run intransparent, because then no simple optical level control by the operator is more possible.
- the dust container to avoid permanent visibility of the dust container located in the dust container and to avoid a concomitant visually unfavorable impression is partly reflective and partly transparent.
- the dust container should then be reflective when viewed from the outside and in normal lighting conditions and thus opaque.
- a lighting of the dust container is activated during the suction operation, which illuminates the interior of the dust container, which should therefore be visible from the outside.
- the DE 20 2010 006 456 U determined.
- a vacuum cleaner robot is described as a device with a luminous in an environment-dependent color housing.
- the vacuum robot is to be equipped with a housing which, at least in parts, is optically transmissive and transparent is such that light coupled into the transmissive part propagates there and is visible upon viewing the outer surface.
- the invention thus presents the problem of providing a further embodiment of a vacuum cleaner in which the content of a dust container enclosed by the vacuum cleaner can be made visible if necessary.
- a bagless vacuum cleaner with a dust container having the features of patent claim 1. It is in a bagless, a dust container comprehensive vacuum cleaner of the type mentioned, in particular a bagless vacuum cleaner with a dust container, an intermediate filter, an exhaust filter, a suction fan and a controller for the vacuum cleaner, provided that the dust container wholly or partly of a chromogenic material manufactured or coated with such a material and thus can be influenced in its transparency.
- controllable in its transparency used here and hereinafter means that the material itself changes its optical properties between transparent (transparent or essentially transparent) and non-transparent / opaque or substantially opaque).
- the transparency of the dust container can be influenced due to its material properties, in a transparent state of the dust container or a transparent state of portions of the dust container further optical level control by the user is possible.
- In an opaque state disturbs dust that is reflected on the inner surfaces of the dust container, not and otherwise about perceived as unhygienic impression of the dust container or the vacuum cleaner is avoided.
- the chromogenic material for the dust container or for coating the dust container is a chromogenic functional polymer. Chromogenic material is carefully selected from luminescent material and the effect of electroluminescence (on that in the DE 10 2007 011 457 A proposed approach). In a special form of a chromogenic material in the form of electrochromic material changes when it creates an electrical voltage whose transparency, so its transparency. In electroluminescence, light is emitted when an electrical voltage is applied. The exploitation of the effect of electroluminescence is thus compared to conventional bulbs only an alternative way to illuminate the interior of a dust container, but causes no change in the transparency of the dust container due to its material properties.
- the transparency of the dust container can be influenced by the approach proposed here, by this in its entirety or at least in sections, which then act like a window or the like, made of a chromogenic material, in particular a chromogenic functional polymer.

- the chromogenic material is an electrochromic material and the dust container has electrodes for activating the electrochromic material.
- Electrochromic material has the advantage that its transparency can be influenced by a current flow and / or an external electromagnetic field. In this way, the transparency of the dust container can be influenced particularly easily and without problems.
- the dust container can be removed from the vacuum cleaner and the electrodes associated with the dust container can be connected to the vacuum cleaner with a circuit for activating the electrochromic material when the dust container is combined.
- the dust container continues to be removed for cleaning purposes or the like from the vacuum cleaner.
- a dust container for a bagless vacuum cleaner is usually kept in a forced operation or a lock in the vacuum cleaner, so that no dust leaks during operation and the suction power can be provided.
- defined positions for the dust container with respect to the surrounding interior of the vacuum cleaner can be used to provide contact points for contacting the electrodes on an outer surface of the vacuum cleaner.
- the circuit for activating the electrochromic material can be influenced via an operating element of the vacuum cleaner. Then the user can choose whether the dust container should be transparent or non-transparent.
- a control element for influencing the transparency of the dust container is an operating device on a handle of the vacuum cleaner into consideration, especially when the bagless vacuum cleaner is designed as a so-called Stabstaubsauger, as a vacuum cleaner or as a table vacuum cleaner.
- the operating device comprises a switch as a control element for influencing the circuit for activating the electrochromic material
- a transparency or intransparency of the electrochromic material is associated with the two switching positions of such a switch.
- the user can thus easily select and change the state of the dust container.
- a switch is a button or the like into consideration. Upon actuation of a button can be provided that the electrochromic material is activated only during the actuation period of the probe in terms of transparency of the dust container. In a particular embodiment, it is also contemplated that a short-term actuation of the probe is sufficient and the activation of the electrochromic material with respect to a transparency of the dust container is then automatically for a predetermined or predetermined duration.
- Another embodiment of the bagless vacuum cleaner is characterized in that the activation of the electrochromic material takes place automatically and at predetermined or predefinable points in time, in particular at predetermined or predefinable times for a predetermined or predefinable duration.
- the switch-on of the vacuum cleaner is considered, because it is sometimes necessary to check whether the intended suction can still be performed or whether previously required a drainage of the dust container is.
- Alternatively or additionally comes as a date for such activation of the electrochromic material and the time of turning off the bagless vacuum cleaner into consideration, because it may be useful to empty the dust container after use of the vacuum cleaner, if its degree of filling suggests this.
- the activation of the electrochromic Material during operation of the bagless vacuum cleaner automatically, for example, at equidistant times, done so that the user can judge the suction result based on the progressive degree of filling of the dust container.
- FIG. 1 shows a bagless vacuum cleaner 10 known in the art in one embodiment as a vacuum cleaner.
- This has a specialist in terminology sometimes referred to as a cyclone 12 centrifugal (dust container 12).
- This is downstream of an intermediate filter 14 (fine dust filter) and an exhaust filter 16 in the direction of adjusting in operation Saug Kunststoffstroms.
- a blower 18 is provided in a conventional manner.
- a vacuum cleaner control 20 is provided for controlling the bagless vacuum cleaner 10.
- the user of the bagless vacuum cleaner 10 can influence its operating mode by making adjustments to an operating device or the like (FIG. 3), which are evaluated by the vacuum cleaner control 20 and influence, for example, the speed of the fan 18 and thus the suction power.
- the dust container 12 is made wholly or predominantly of a transparent polymer, on the one hand to enable the user to look into the dust container 12 and, on the other hand, to function as the cyclone with the cyclone vortex forming in the dust container 12, to make the sucked dust into rotation, to make visible.

- Particularly suitable electrochromic materials are electrochromic polymers in which the transparency of the polymer can be changed by the application of an electric field / voltage, as is spaced apart from one another between two arranged electrodes 22, as in FIG. 2 shown.
- the electric field or the voltage between the electrodes 22 is switchable by means of the vacuum cleaner control 20 in the sense that the electrodes 22 and the circuit in which they are integrated, are effective for influencing the transparency of the dust container 12.
- FIG. 3 shows a provided for acting on the vacuum cleaner control 20 operating device 24.

- a control element 28 in the form of a push button or a pressure switch with two switch positions, the above-mentioned circuit is closed or a means for closing this circuit is activated upon actuation of the control element 28, so that an electric field is established between the electrodes 22 or an existing electrical Field is turned off.
- control element 28 When the control element 28 is designed as a button, when it is actuated, a time counter (not shown) can be started, which shuts off the electric field / voltage after the expiration of the counter and thus after a defined period of time to return the dust container 12 back into to set the intransparent state. Thus, it is only possible to look into the dust container 12 for a short time in order, for example, to control the filling level / loading state. If the control element 28 is designed as a switch, there is an easy way for the user to decide whether the dust container 12 should be switched transparent or non-transparent. It is therefore at the discretion of the user which transparency state he chooses.
- This variant can also be combined with the expiration of a counter or an otherwise suitably defined period of time, so that the dust container 12, for example, each time when switching the switching position of acting as a control element switch 28 is switched to transparent during the expiration of each suitably defined period of time ,
- control element 28 may additionally or alternatively to a positioning in or on an operating device 24, which is usually attached to the outside of the sucker housing of the bagless vacuum cleaner 10, also on a handle or the like, for example, a handle member of a suction hose in one embodiment of the bagless vacuum cleaner 10 as a vacuum cleaner, arranged be. Then, the control element 28 acts as a kind of remote control for influencing the transparency of the dust container 12.

Description
Die Erfindung betrifft einen beutellosen Staubsauger mit einem Staubbehälter. Beutellose Staubsauger sind an sich bekannt. Diese arbeiten mit einem Fliehkraftabscheider und das äußere Gehäuse eines solchen mitunter auch als Zyklon bezeichneten Fliehkraftabscheiders fungiert in dem beutellosen Staubsauger als Staubbehälter. In diesem Staubbehälter wird der aufgesaugte Staub zu einem großen Teil gesammelt. Während des Betriebs verschmutzen allerdings die innenliegenden Flächen des Staubbehälters, insbesondere durch dort niedergeschlagenen Feinstaub.The invention relates to a bagless vacuum cleaner with a dust container.

In this dust container, the absorbed dust is collected to a large extent. During operation, however, pollute the inner surfaces of the dust container, in particular by there precipitated fine dust.
Solche beutellosen Staubsauger sind also insofern verbesserungsfähig, als ein transparent ausgeführter Staubbehälter im Verlauf des Betriebs mitunter aufgrund von aufgesaugtem Staub, insbesondere Feinstaub, ein unhygienisches Erscheinungsbild erhält, wenn sich der Staub an den Innenflächen des Staubbehälters niederschlägt. Umgekehrt kann der Staubbehälter aber auch nicht intransparent ausgeführt werden, weil dann keine einfache optische Füllstandskontrolle durch den Bediener mehr möglich ist.Such bagless vacuum cleaners are thus capable of improvement insofar as a transparent dust container in the course of operation sometimes due to sucked up dust, especially fine dust, an unhygienic appearance receives when the dust is reflected on the inner surfaces of the dust container.

Erfindungsgemäß wird dieses Problem durch einen beutellosen Staubsauger mit einem Staubbehälter mit den Merkmalen des Patentanspruchs 1 gelöst. Dabei ist bei einem beutellosen, einen Staubbehälter umfassenden Staubsauger der eingangs genannten Art, insbesondere einem beutellosen Staubsauger mit einem Staubbehälter, einem Zwischenfilter, einem Abluftfilter, einem Saugergebläse und einer Steuerung für den Staubsauger, vorgesehen, dass der Staubbehälter ganz oder teilweise aus einem chromogenen Material gefertigt oder mit einem solchen Material beschichtet und damit in seiner Transparenz beeinflussbar ist. Der hier und im Folgenden verwendete Ausdruck "in seiner Transparenz beeinflussbar" meint dabei, dass das Material selbst seine optischen Eigenschaften gesteuert zwischen transparent (durchsichtig oder im Wesentlichen durchsichtig) und intransparent/undurchsichtig oder im Wesentlichen undurchsichtig) wechselt.According to the invention, this problem is solved by a bagless vacuum cleaner with a dust container having the features of
Indem der Staubbehälter aufgrund von dessen Materialeigenschaften in seiner Transparenz beeinflussbar ist, ist bei einem transparenten Zustand des Staubbehälters oder einem transparenten Zustand von Abschnitten des Staubbehälters weiterhin eine optische Füllstandskontrolle durch den Benutzer möglich. Bei einem intransparenten Zustand stört Staub, der sich an den Innenflächen des Staubbehälters niederschlägt, nicht und ein ansonsten etwa als unhygienisch empfundener Eindruck des Staubbehälters oder des Staubsaugers wird vermieden.By the transparency of the dust container can be influenced due to its material properties, in a transparent state of the dust container or a transparent state of portions of the dust container further optical level control by the user is possible. In an opaque state disturbs dust that is reflected on the inner surfaces of the dust container, not and otherwise about perceived as unhygienic impression of the dust container or the vacuum cleaner is avoided.
Als chromogenes Material für den Staubbehälter oder zur Beschichtung des Staubbehälters kommt ein chromogenes Funktionspolymer in Betracht. Chromogenes Material ist sorgfältig von lumineszierendem Material und dem Effekt der Elektrolumineszenz (auf dem der in der
Beim hier vorgeschlagenen Ansatz werden aufgrund der Verwendung von chromogenem, insbesondere elektrochromem Material die Materialeigenschaften des Staubsammelbehälters selbst für eine Beeinflussung von dessen Transparenz ausgenutzt. Dies ist auch sorgfältig zu unterscheiden von einer Änderung der Möglichkeiten, in einen Raum, also zum Beispiel einen Staubbehälter, hineinzusehen, wenn dessen Inneres heller als die Umgebung des Betrachters ist. Der letztgenannte Effekt, auf dem der Ansatz in der
Die Transparenz des Staubbehälters lässt sich nach dem hier vorgeschlagenen Ansatz beeinflussen, indem dieser in seiner Gesamtheit oder zumindest in Abschnitten, die dann wie ein Fenster oder dergleichen wirken, aus einem chromogenen Material, insbesondere einem chromogenen Funktionspolymer, gefertigt ist. Alternativ kommt auch in Betracht, den Staubbehälter zum Beispiel aus einem Kunststoff zu fertigen, wobei in dem Staubbehälter dann zumindest abschnittsweise durchsichtige Bereiche gebildet sind. Zumindest diese durchsichtigen Bereiche lassen sich auch mit einem chromogenen Material, insbesondere einem chromogenen Funktionspolymer, beschichten, zum Beispiel indem eine solche Beschichtung dauerhaft aufgetragen oder in Form einer Klebefolie oder dergleichen aufgebracht wird. Alle beschriebenen Varianten und auch solche Varianten, die für den Fachmann anhand der hier vorgestellten Ausführungsformen entnehmbar sind, werden im Folgenden und ohne Verzicht auf eine weitergehende Allgemeingültigkeit als Beeinflussbarkeit der Transparenz des Staubbehälters bezeichnet, und zwar unabhängig davon, ob dies für den Staubbehälter insgesamt oder nur abschnittsweise oder durch Beeinflussung des Materials, aus dem der Staubbehälter gefertigt ist, oder durch Beeinflussung einer auf eine Innen- oder Außenoberfläche des Staubbehälters aufgetragenen Beschichtung erfolgt.The transparency of the dust container can be influenced by the approach proposed here, by this in its entirety or at least in sections, which then act like a window or the like, made of a chromogenic material, in particular a chromogenic functional polymer. Alternatively, it is also possible to manufacture the dust container, for example, from a plastic, wherein transparent areas are then formed in the dust container at least in sections. At least these transparent regions can also be coated with a chromogenic material, in particular a chromogenic functional polymer, for example by permanently applying such a coating or applying it in the form of an adhesive film or the like. All variants described and also those variants which can be inferred to the person skilled in the art on the basis of the embodiments presented here are referred to below as an influencing of the transparency of the dust container without sacrificing any general validity, regardless of whether this is the case for the dust container as a whole or only in sections or by influencing the material from which the dust container is made, or by influencing a applied to an inner or outer surface of the dust container coating.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen. Dabei verwendete Rückbeziehungen weisen auf die weitere Ausbildung des Gegenstandes des Hauptanspruches durch die Merkmale des jeweiligen Unteranspruches hin. Sie sind nicht als ein Verzicht auf die Erzielung eines selbständigen, gegenständlichen Schutzes für die Merkmalskombinationen der rückbezogenen Unteransprüche zu verstehen. Des Weiteren ist im Hinblick auf eine Auslegung der Ansprüche bei einer näheren Konkretisierung eines Merkmals in einem nachgeordneten Anspruch davon auszugehen, dass eine derartige Beschränkung in den jeweils vorangehenden Ansprüchen nicht vorhanden ist.Advantageous embodiments and further developments of the invention will become apparent from the following subclaims. Here used backlinks indicate the further development of the subject matter of the main claim by the features of the respective subclaim. They should not be construed as a waiver of obtaining independent, objective protection for the feature combinations of the dependent claims. Furthermore, with a view to an interpretation of the claims in a closer specification of a feature in a subordinate claim, it is to be assumed that such a restriction does not exist in the respective preceding claims.
Bei einer besonderen Ausführungsform des beutellosen Staubsaugers ist vorgesehen, dass das chromogene Material ein elektrochromes Material ist und der Staubbehälter Elektroden zur Aktivierung des elektrochromen Materials aufweist. Elektrochromes Material hat den Vorteil, dass dessen Transparenz durch einen Stromfluss und/oder ein äußeres elektromagnetischen Feld beeinflussbar ist. Auf diese Weise lässt sich die Transparenz des Staubbehälters besonders leicht und unproblematisch beeinflussen.In a particular embodiment of the bagless vacuum cleaner it is provided that the chromogenic material is an electrochromic material and the dust container has electrodes for activating the electrochromic material. Electrochromic material has the advantage that its transparency can be influenced by a current flow and / or an external electromagnetic field. In this way, the transparency of the dust container can be influenced particularly easily and without problems.
Bei einer weiteren Ausführungsform des beutellosen Staubsaugers ist vorgesehen, dass der Staubbehälter aus dem Staubsauger entnehmbar ist und die dem Staubbehälter zugeordneten Elektroden beim Kombinieren des Staubbehälters mit dem Staubsauger mit einem Stromkreis zur Aktivierung des elektrochromen Materials verbindbar sind. Bei dieser Ausführungsform bleibt der Staubbehälter weiterhin zu Reinigungszwecken oder dergleichen aus dem Staubsauger entnehmbar. Indem zum Beispiel im Anschluss an eine Reinigung des Staubbehälters beim Wiedereinsetzen des Staubbehälters in den Staubsauger, also beim Kombinieren des Staubbehälters mit dem Staubsauger, die dem Staubbehälter zugeordneten Elektroden mit einem Stromkreis zur Aktivierung des elektrochromen Materials selbsttätig verbunden werden, ist der Benutzer des Staubsaugers nicht damit belastet, etwa selbst für den Anschluss der Elektroden und die Wirksamkeit des Stromkreises zur Aktivierung des elektrochromen Materials zu sorgen. Ein Staubbehälter für einen beutellosen Staubsauger wird üblicherweise in einer Zwangsführung oder einer Arretierung im Staubsauger gehalten, damit im Betrieb kein Staub austritt und die Saugleistung erbracht werden kann. Damit ergeben sich definierte Positionen für den Staubbehälter in Bezug auf den umgebenden Innenraum des Staubsaugers. Diese definierten Positionen können dafür genutzt werden, auf einer Außenfläche des Staubsaugers Kontaktstellen zur Kontaktierung der Elektroden vorzusehen. Beim Kombinieren des Staubbehälters mit dem Staubsauger lassen sich solche Kontaktstellen leicht mit entsprechenden, dem Innenraum des Staubsaugers zugeordneten Kontaktelementen, zum Beispiel Federkontakten oder dergleichen, kontaktieren.In a further embodiment of the bagless vacuum cleaner it is provided that the dust container can be removed from the vacuum cleaner and the electrodes associated with the dust container can be connected to the vacuum cleaner with a circuit for activating the electrochromic material when the dust container is combined. In this embodiment, the dust container continues to be removed for cleaning purposes or the like from the vacuum cleaner. By, for example, following a cleaning of the dust container when reinserting the dust container in the vacuum cleaner, so when combining the dust container with the vacuum, the dust container associated electrodes are automatically connected to a circuit for activating the electrochromic material, the user of the vacuum cleaner is not burdened with, for example, even for the connection of the electrodes and the effectiveness of the circuit to activate the electrochromic material. A dust container for a bagless vacuum cleaner is usually kept in a forced operation or a lock in the vacuum cleaner, so that no dust leaks during operation and the suction power can be provided. With that result defined positions for the dust container with respect to the surrounding interior of the vacuum cleaner. These defined positions can be used to provide contact points for contacting the electrodes on an outer surface of the vacuum cleaner. When combining the dust container with the vacuum cleaner, such contact points can be easily contact with corresponding, the interior of the vacuum cleaner associated contact elements, such as spring contacts or the like.
Bei einer besonderen Ausführungsform des beutellosen Staubsaugers ist vorgesehen, dass der Stromkreis zur Aktivierung des elektrochromen Materials über ein Bedienelement des Staubsaugers beeinflussbar ist. Dann kann der Benutzer wählen, ob der Staubbehälter transparent oder intransparent sein soll. Als besonderer Ort für ein derartiges Bedienelement zur Beeinflussung der Transparenz des Staubbehälters kommt eine Bedieneinrichtung an einem Handgriff des Staubsaugers in Betracht, speziell wenn der beutellose Staubsauger als sogenannter Stabstaubsauger, als Bodenstaubsauger oder als Tischstaubsauger ausgeführt ist.In a particular embodiment of the bagless vacuum cleaner is provided that the circuit for activating the electrochromic material can be influenced via an operating element of the vacuum cleaner. Then the user can choose whether the dust container should be transparent or non-transparent. As a special place for such a control element for influencing the transparency of the dust container is an operating device on a handle of the vacuum cleaner into consideration, especially when the bagless vacuum cleaner is designed as a so-called Stabstaubsauger, as a vacuum cleaner or as a table vacuum cleaner.
Wenn die Bedieneinrichtung einen Schalter als Bedienelement zur Beeinflussung des Stromkreises zur Aktivierung des elektrochromen Materials umfasst, ist mit den beiden Schaltstellungen eines solchen Schalters eine Transparenz bzw. Intransparenz des elektrochromen Materials assoziiert. Der Benutzer kann also den Zustand des Staubbehälters leicht wählen und ändern. Als Alternative zu einem Schalter kommt ein Taster oder dergleichen in Betracht. Bei einer Betätigung eines Tasters kann vorgesehen sein, dass das elektrochrome Material nur während der Betätigungsdauer des Tasters im Hinblick auf eine Transparenz des Staubbehälters aktiviert ist. Bei einer besonderen Ausführungsform kommt auch in Betracht, dass eine kurzzeitige Betätigung des Tasters ausreicht und die Aktivierung des elektrochromen Materials im Hinblick auf eine Transparenz des Staubbehälters dann automatisch für eine vorgegebene oder vorgebbare Dauer erfolgt.If the operating device comprises a switch as a control element for influencing the circuit for activating the electrochromic material, a transparency or intransparency of the electrochromic material is associated with the two switching positions of such a switch. The user can thus easily select and change the state of the dust container. As an alternative to a switch is a button or the like into consideration. Upon actuation of a button can be provided that the electrochromic material is activated only during the actuation period of the probe in terms of transparency of the dust container. In a particular embodiment, it is also contemplated that a short-term actuation of the probe is sufficient and the activation of the electrochromic material with respect to a transparency of the dust container is then automatically for a predetermined or predetermined duration.
Eine weitere Ausführungsform des beutellosen Staubsaugers zeichnet sich dadurch aus, dass die Aktivierung des elektrochromen Materials automatisch und zu vorgegebenen oder vorgebbaren Zeitpunkten, insbesondere zu vorgegebenen oder vorgebbaren Zeitpunkten für eine vorgegebene oder vorgebbare Dauer, erfolgt. Als Zeitpunkt für eine Aktivierung des elektrochromen Materials im Hinblick auf eine Transparenz des Staubbehälters kommt zum Beispiel der Einschaltzeitpunkt des Staubsaugers in Betracht, weil dann mitunter notwendig ist, zu prüfen, ob der beabsichtigte Saugvorgang noch ausgeführt werden kann oder ob vorher eine Entleerung des Staubbehälters erforderlich ist. Alternativ oder zusätzlich kommt als Zeitpunkt für eine solche Aktivierung des elektrochromen Materials auch der Zeitpunkt des Ausschaltens des beutellosen Staubsaugers in Betracht, weil es sinnvoll sein kann, den Staubbehälter nach Gebrauch des Staubsaugers zu entleeren, wenn dessen Füllgrad dies nahe legt. Zusätzlich oder alternativ kommt auch in Betracht, dass die Aktivierung des elektrochromen Materials während des Betriebs des beutellosen Staubsaugers automatisch, zum Beispiel zu äquidistanten Zeitpunkten, erfolgt, so dass der Benutzer das Saugergebnis anhand des fortschreitenden Füllgrades des Staubbehälters beurteilen kann.Another embodiment of the bagless vacuum cleaner is characterized in that the activation of the electrochromic material takes place automatically and at predetermined or predefinable points in time, in particular at predetermined or predefinable times for a predetermined or predefinable duration. As a timing for activation of the electrochromic material in terms of transparency of the dust container, for example, the switch-on of the vacuum cleaner is considered, because it is sometimes necessary to check whether the intended suction can still be performed or whether previously required a drainage of the dust container is. Alternatively or additionally comes as a date for such activation of the electrochromic material and the time of turning off the bagless vacuum cleaner into consideration, because it may be useful to empty the dust container after use of the vacuum cleaner, if its degree of filling suggests this. Additionally or alternatively, it is also considered that the activation of the electrochromic Material during operation of the bagless vacuum cleaner automatically, for example, at equidistant times, done so that the user can judge the suction result based on the progressive degree of filling of the dust container.
Der hier um im Folgenden beschriebene Ansatz kommt grundsätzlich für jede denkbare Ausführungsform eines Staubsaugers in Betracht, also für Bodenstaubsauger, Stabstaubsauger, Tisch- oder Handstaubsauger, usw. Da speziell bei Tisch- oder Handstaubsaugern zumeist aus Platz- und/oder Kostengründen auf aufwendige Messmethoden zur Beurteilung des Staubraumfüllstandes verzichtet werden muss, ist hier eine Möglichkeit zur optischen Füllstandskontrolle besonders relevant. Solche Staubsauger werden aber auch in Wohnräumen aufbewahrt, z.B. in Küche, Wohn- oder Esszimmer, so dass hier die dauerhafte Wahrnehmbarkeit des eingesaugten Schmutzes besonders störend sein kann. Deshalb kommt der hier vorgeschlagene Ansatz, wenn auch nicht ausschließlich, so doch ganz besonders für solche Staubsauger in Betracht.The approach described here below is basically for every conceivable embodiment of a vacuum cleaner into consideration, ie for vacuum cleaner, vacuum cleaner, table or vacuum cleaner, etc. Since especially for table or vacuum cleaners mostly for space and / or cost reasons to elaborate methods of measurement Assessment of Staubraumfüllstandes must be waived, here is a possibility for optical level control particularly relevant. However, such vacuum cleaners are also stored in living quarters, e.g. in kitchen, living room or dining room, so that the permanent perception of sucked dirt can be particularly disturbing here. Therefore, the approach proposed here, though not exclusively, at least especially for such vacuum cleaners into consideration.

Bei im Stand der Technik bekannten beutellosen Staubsaugern 10 wird der Staubbehälter 12 ganz oder überwiegend aus einem transparenten Polymer gefertigt, um dem Benutzer einerseits einen Blick in den Staubbehälter 12 zu ermöglichen und andererseits die Funktion des Zyklons mit dem sich in dem Staubbehälter 12 ausbildenden Zyklonwirbel, der den aufgesaugten Staub in Rotation versetzt, sichtbar zu machen. Bei einzelnen beutellosen Staubsaugern 10 werden auch Staubbehälter 12 verwendet, die aus einem intransparenten Polymer gefertigt sind.In the
Dem Staubbehälter 12 sind dabei bei dem hier als elektrochrom angenommenen chromogenen Material des Staubbehälters 12 Elektroden 22 zugeordnet, die zur Aktivierung des elektrochromen Materials, aus dem der Staubbehälter 12 ganz oder teilweise gefertigt ist oder mit dem der Staubbehälter 12 ganz oder abschnittsweise beschichtet ist, wirksam sind. Die Elektroden 22 stehen mit der Staubsaugersteuerung 20 in Wirkverbindung, indem die Elektroden 22 Bestandteil eines nicht näher dargestellten und von der Staubsaugersteuerung 20 ausgehenden oder zumindest durch die Staubsaugersteuerung 20 beeinflussbaren Stromkreises sind. Als elektrochromes Material kommen speziell elektrochrome Polymere in Betracht, bei denen sich die Transparenz des Polymers durch das Anlegen eines elektrischen Feldes/einer elektrischen Spannung verändern lässt, wie sich dies zwischen zwei beabstandet voneinander angeordneten Elektroden 22, wie in
Wenn das Bedienelement 28 als Taster ausgeführt ist, kann bei dessen Betätigung ein Zeitzähler (nicht dargestellt) gestartet werden, der das elektrische Feld/die elektrische Spannung nach Ablauf des Zählers und damit nach Verstreichen einer definierten Zeitspanne wieder abschaltet, um den Staubbehälter 12 zurück in den intransparenten Zustand zu versetzen. So kann nur während einer kurzen Zeit in den Staubbehälter 12 geschaut werden, um beispielsweise den Füllstand/Beladungszustand zu kontrollieren. Wenn das Bedienelement 28 als Schalter ausgeführt ist, besteht für den Benutzer eine einfache Möglichkeit, zu entscheiden, ob der Staubbehälter 12 transparent oder intransparent geschaltet sein soll. Es liegt somit im Ermessen des Benutzers, welchen Transparenzzustand er wählt. Diese Variante lässt sich auch mit dem Ablauf eines Zählers oder einer sonst in geeigneter Weise definierten Zeitdauer kombinieren, so dass der Staubbehälter 12 zum Beispiel jedes Mal beim Wechseln der Schaltstellung eines als Bedienelement 28 fungierenden Schalters während des Ablaufs der jeweils geeignet definierten Zeitdauer transparent geschaltet wird.When the
Weiter kommt in Betracht, das elektrische Feld unmittelbar, insbesondere nur unmittelbar nach dem Einschalten des beutellosen Staubsaugers 10 über die Elektroden 22 an den Staubbehälter 12 anzulegen und dieses nach Ablauf einer definierten Zeit, zum Beispiel zwei Minuten, wieder abzuschalten. So besitzt der Benutzer die Möglichkeit, sofort nach dem Einschalten des beutellosen Staubsaugers 10 den Füllstand/den Beladungszustand des Staubbehälters 12 zu überprüfen. Das in

Die Transparenz des Staubbehälters 12 kann stufenlos oder zumindest im Wesentlichen stufenlos, nämlich in unterschiedlichen Transparenzgraden, durch ein variables elektrisches Feld/eine variable elektrische Spannung über die Staubsaugersteuerung 20 eingestellt werden. Der Grad der Transparenz kann dabei zum Beispiel füllgradabhängig gesteuert werden, so dass ein hoher Füllgrad beispielsweise mit einer vollständigen Transparenz einhergeht. Als Füllgradsensor kommt beispielsweise ein im Staubbehälter 12 befindlicher optischer Niveausensor zum Einsatz.The transparency of the
Die Darstellung in
Der Staubbehälter 12 ist größtenteils blickdicht und umfasst zumindest ein in seiner Transparenz beeinflussbares Sichtfenster 38. Das Sichtfenster 38 ist hier an einer Seite des Staubsaugers 10 angeordnet, es kann jedoch auch an einer anderen Stelle des Staubbehälters 12 angeordnet sein, die dazu geeignet ist, dem Bediener möglichst komfortabel Einsicht in den Staubbehälter 12 zu gewähren. Auch kann auf der anderen, in die Zeichnungsebene hinein zeigenden Seite des Staubbehälters 12 ein ähnliches Sichtfenster 38 angeordnet sein. Die Form des Sichtfensters 38 beschränkt sich keinesfalls auf die hier gezeigte Form und als Form des Sichtfensters 38 kann jede beliebige Form gewählt werden. Auch die Größe des Sichtfensters 38 im Vergleich zum Staubbehälter 12 ist nicht auf die hier gezeigte Größe beschränkt. Das Sichtfenster 38 kann z.B. auch ein von einer Seite des Staubbehälters 12 zur anderen Seite des Staubbehälters 12 durchgängiges Sichtfenster (nicht dargestellt) sein. Auch der gesamte Staubbehälter 12 kann aus einem in seiner Transparenz beeinflussbaren Material sein. Ein solcher Staubbehälter 12 und ein Staubbehälter 12 mit einem solchen Sichtfenster 38 sind ebenfalls Beispiele für einen ganz oder teilweise aus einem chromogenen Material gefertigten oder damit beschichteten Staubbehälter 12. Durch das elektrochrome Material, welches bei Anlegen eines elektrischen Felds oder bei einem Stromfluss seine optischen Eigenschaften z.B. von undurchsichtig nach durchsichtig ändern kann, wird auch das Sichtfenster 38 in seiner Transparenz beeinflussbar. Auf diese Weise kann die Einsicht in den Staubbehälter 12, d.h. das Sichtbarmachen des Inhalts des Staubbehälters 12, zu unterschiedlichen Zeiten und/oder Zuständen und/oder auf Anforderung durch den Bediener ermöglicht werden.The
Im Vergleich zu der in
Das Leuchtmittel 40 kann außerhalb des Staubbehälters 12 im Gehäuse des Staubsaugers 10 angeordnet sein. Es ist dann eine transparente Abtrennung zwischen dem Leuchtmittel 40 und dem Staubbehälter 12 vorgesehen, durch die das Leuchtmittel 40 das Innere des Staubbehälters 12 beleuchten kann. Das Leuchtmittel 40 kann alternativ auch im Staubbehälter 12 angeordnet sein. Dann umfasst der Staubbehälter 12 ein elektrisches Kontaktmittel (nicht dargestellt), mit dem das Leuchtmittel 40 elektrisch mit einer im Gehäuse des Staubsaugers 10 angebrachten Kontaktstelle kontaktierbar und so mit der Staubsaugersteuerung 20 verbindbar ist. Das elektrische Kontaktmittel ist vorzugsweise so ausgeführt, dass beim Trennen des Staubbehälters 12 vom Gehäuse des Staubsaugers 10, z. B. zum Leeren des Staubbehälters 12, der elektrische Kontakt getrennt wird und bei Wiedereinsetzen des Staubbehälters 12 der elektrische Kontakt unmittelbar wiederhergestellt wird.The
Alternativ oder zusätzlich zur Aktivierung während des Saugbetriebs kann das Leuchtmittel 40 und das elektrochrome Material auch aktiviert werden, wenn der Staubsauger 10 nicht in Betrieb ist. Der Bediener muss den Staubsauger 10 dann nicht extra starten, wenn er nur den Füllstand des Staubbehälters 12 kontrollieren will. Dazu kann der Staubsauger 10 z.B. einen zusätzlichen Schaltknopf (in
Bei einer Kombination der Beleuchtung des Innenraums des Staubbehälters 12 mit einer Beeinflussung der Transparenz des Staubbehälters 12 kann mithilfe der Staubsaugersteuerung 20 die Beleuchtung gleichzeitig oder in einer vorgegebenen oder vorgebbaren zeitlichen Korrelation zur Aktivierung des elektrochromen Materials erfolgen. Zusätzlich oder alternativ kann des Weiteren die Spannungsversorgung für das Leuchtmittel 40 und/oder die Spannungsversorgung zur Aktivierung des elektrochromen Materials auf- und/oder abgedimmt werden.With a combination of the illumination of the interior of the
Um die Innenoberfläche des Staubbehälters 12 gegen Abrasion durch die sich in Bewegung befindlichen Staubpartikel zu schützen, speziell wenn der Staubbehälter 12 insgesamt aus einem chromogenen oder elektrochromen Material gefertigt ist oder sich eine solche Beschichtung auf der Innenoberfläche des Staubbehälters 12 befindet, wird das chromogene / elektrochrome Material durch die Beimischung von Additiven gleichzeitig kratzfest ausgeführt.In order to protect the inner surface of the
Es versteht sich, dass zur Ausführung des Staubbehälters 12 als in seiner Transparenz beeinflussbarer Staubbehälter 12 auch chromogene Gläser, insbesondere elektrochrome Gläser, Verwendung finden können. Bei einer solchen Ausführungsvariante kommt ein schichtartiger Aufbau des Staubbehälters 12 in Betracht, wobei sich eine elektrochrome Glasschicht zwischen einem die Innenoberfläche des Staubbehälters 12 bildenden kratzfesten Glaskörper und einem zweiten, außen liegenden Glaskörper mit herkömmlichen Materialeigenschaften befindet.It goes without saying that chromogenic glasses, in particular electrochromic glasses, can be used to carry out the
Insgesamt kann mit dem hier vorgeschlagenen beutellosen Staubsauger 10 mit dem in seiner Transparenz beeinflussbaren Staubbehälter 12 ein speziell im Betrieb hochwertig anmutender beutelloser Staubsauger 10 geschaffen werden.Overall, with the
