Description

Die Erfindung betrifft zunächst einen Elektro-Staubsauger mit einer Anordnung zur Erfassung eines eingesetzten Filterelements.The invention first relates to an electric vacuum cleaner with an arrangement for detecting a filter element used.

Elektro-Staubsauger mit einer Anordnung zur Erfassung des in dem Elektro-Staubsauger eingesetzten Filterelements sind bekannt. Mittels solcher Anordnungen wird der betriebsgerechte Zustand des Elektro-Staubsaugers kontrolliert, indem über diese Anordnung festgestellt wird, ob ein betriebsgerechter Filter vorgesehen ist, darüber hinaus gegebenenfalls ob dieser korrekt eingesetzt ist und weiter gegebenenfalls ob dieser neu ist. So ist weiter beispielsweise bekannt, das Filterelement mit einem aus einem Einwirkungsbereich entfernbaren Element zu versehen, um so auf optischem und/oder mechanischem Wege das korrekte Einsetzen eines für den Betrieb geeigneten Filterelements zu erfassen. Nach erstmaligem Einsetzen wird das beispielsweise einen geräteseitigen Schalter oder dergleichen beeinflussende Element in eine Nichtwirkstellung verbracht, so dass ein Wiedereinsetzen eines gebrauchten Filterelements zu einer entsprechenden geräteseitigen Detektion führt.Electric vacuum cleaners with an arrangement for detecting the filter element used in the electric vacuum cleaner are known. By means of such arrangements, the operational state of the electric vacuum cleaner is controlled by this arrangement determines whether a proper filter is provided, in addition, if appropriate, if this is used correctly and further, if necessary, whether this is new. For example, it is further known to provide the filter element with a removable from an area of action element so as to detect the correct insertion of a suitable filter element for operation by optical and / or mechanical means. After initial insertion, for example, a device-side switch or the like influencing element is spent in a non-operative position, so that a re-insertion of a used filter element leads to a corresponding device-side detection.

Aus der WO2006/0077190 A , welches Stand der Technik nach Art, 54(3) EPÜ ist, ist eine Anordnung zur Erfassung eines in einem Elektro-Staubsauger eingesetzten Filterelementes als neu bekannt. Die Erfassung wird durch eine am Filterrahmen ausgebildete Betätigungslasche erreicht, die beim Einbringen des Filters in die Aufnahmekammer des Elektro-Staubsaugers einen Betriebsstundenzähler zurücksetzt. Durch das Einbringen wird die Betätigungslasche in eine bleibende Nichtbetätigungsstellung versetzt. Bei einem erneuten Einbringen dieses Filters in die Aufnahmekammer setzt dieser Filter den Betriebsstundenzähler nicht mehr zurück und ist damit als nicht neuer oder falscher Filter identifizierbar.From the WO2006 / 0077190 A What is state of the art under Art. 54 (3) EPC is an arrangement for detecting a filter element used in an electric vacuum cleaner as new. The detection is achieved by an operating tab formed on the filter frame, which resets an operating hours counter when the filter is introduced into the receiving chamber of the electric vacuum cleaner. By introducing the actuating tab is placed in a permanent non-actuated position. When re-introducing this filter into the receiving chamber, this filter no longer resets the hour meter and is therefore identifiable as a non-new or incorrect filter.

Im Weiteren ist zum Stand der Technik auf die DE 197 25 990 A1 , die US 5 378 254 A , die EP 0 934 721 A , die EP 0 895 744 A1 und die WO 2004/004537 A zu verweisen.Furthermore, the state of the art on the DE 197 25 990 A1 , the US 5,378,254 A , the EP 0 934 721 A , the EP 0 895 744 A1 and the WO 2004/004537 A to refer.

Der Erfindung stellt sich die Aufgabe, einen Elektro-Staubsauger mit einer vorteilhaften Anordnung zur Erfassung eines eingesetzten Filterelementes als neu und ggf. in bestimmter Weise ausgebildet anzugeben, sowie weiterhin ein hierfür geeignetes Filterelement anzugeben.The invention has as its object to provide an electric vacuum cleaner with an advantageous arrangement for detecting a filter element used as new and possibly designed in a certain way, and continue to provide a suitable filter element for this purpose.

Diese Aufgabe ist zunächst beim Gegenstand des Anspruches 1 gelöst, wobei darauf abgestellt ist, dass die Erfassung aufgrund einer elektrischen Schaltung erreicht ist, wobei das Filterelement zumindest zunächst Teil der elektrischen Schaltung ist und in diesem Zustand ein Gebrauchszähler auf Null gesetzt wird und/oder in Abhängigkeit einer Öffnung des das Filterelement aufnehmenden Gehäuses bei Weiterverwendung desselben Filterelements eine Fehlermeldung ausgelöst wird. Zufolge dieser Ausgestaltung ist eine Erfassung eines in einem Elektro-Staubsauger eingesetzten Filterelements als neu und ggf. in bestimmter Weise ausgebildet auf elektrischem Wege erreicht. Das Filterelement ist hierzu zumindest zunächst Teil der elektrischen Schaltung, schließt entsprechend bevorzugt einen der Filterelementerfassung dienenden Stromkreis. Das Filterelement fungiert in dieser Situation im übertragenen Sinne als Schalter. In Abhängigkeit von einem solchen Schließen eines Schaltungskreises wird entsprechend einer Ausführungsform ein geräteseitiger Gebrauchszähler auf Null gesetzt. Insbesondere für Filterelemente in Form von Feinstfiltern oder dergleichen, deren Füllgrad nicht oder nur bedingt erfasst werden kann, sind solche Gebrauchszähler von Vorteil. Anhand einer vorgegebenen Maximal-Betriebsstundenzahl wird dem Benutzer beispielsweise über eine optische Anzeige der nötige Wechsel des Filterelementes angezeigt. Der hiernach zu erfolgende Einsatz eines neuen Filterelements bedingt das Rücksetzen des Gebrauchszählers.This object is first achieved in the subject matter of claim 1, wherein it is pointed out that the detection is achieved due to an electrical circuit, wherein the filter element is at least initially part of the electrical circuit and in this state, a usage counter is set to zero and / or in Depending on an opening of the filter element receiving housing upon further use of the same filter element an error message is triggered. According to this embodiment, a detection of a filter element used in an electric vacuum cleaner as new and possibly formed in a certain way is achieved by electrical means. For this purpose, the filter element is at least initially part of the electrical circuit, correspondingly preferably closing a circuit that serves to detect the filter element. The filter element acts in this situation in a figurative sense as a switch. In response to such closing of a circuit circuit, a device-side usage counter is set to zero according to one embodiment. In particular, for filter elements in the form of ultrafine filters or the like, the degree of filling can not or only partially be detected, such utility meter are beneficial. Based on a predetermined maximum number of operating hours, the user is displayed, for example via a visual display of the necessary change of the filter element. The use of a new filter element to be performed hereafter requires resetting the utility meter.

Die Verwendung eines Gebrauchszählers kann darüber hinaus auch in Zusammenhang mit einem Filterbeutel zur Aufnahme des aufzusaugenden Grobschmutzes vorgesehen sein, wobei dann auch bei einer solchen Konfiguration der Einsatz eines neuen Staubfilterbeutels die Rückstellung des Gebrauchszählers auf Null zur Folge hat. Der Einsatz eines bereits gebrauchten Filterelements lässt den Gebrauchszähler unbeeinflusst.The use of a utility meter can also be provided in connection with a filter bag for receiving the aufzuschaugenden coarse dirt, then even with such a configuration, the use of a new dust filter bag has the provision of the utility meter to zero result. The use of an already used filter element leaves the use counter unaffected.

Darüber hinaus kann auch eine Fehlermeldung ausgelöst werden, sobald dasselbe Filterelement zur Weiterverwendung wieder in das dieses aufnehmende Gehäuse eingesetzt wird, dies in Abhängigkeit von einer Öffnung des Gehäuses. Entsprechend bedarf es nach einem Öffnen des das Filterelement aufnehmenden Gehäuses des Einsetzens eines neuen, den entsprechenden Teil einer elektrischen Schaltung aufweisenden Filterelements.In addition, an error message can be triggered as soon as the same filter element is reused in the receiving this housing, depending on an opening of the housing. Accordingly, after opening the filter element accommodating housing of the insertion of a new, the corresponding part of an electrical circuit having a filter element is required.

In bevorzugter Ausgestaltung verliert das Filterelement nach Einsetzen in den Staubsauger und in bevorzugter Weise nach hiernach erfolgendem Erst-Einschalten des Staubsaugers seine Funktion als Teil der elektrischen Schaltung, was zur Folge hat, dass dieses Filterelement bei einem Wiederverwenden als nicht neu erfasst wird. Weiter ist mittels der in dem Filterelement vorgesehenen elektrischen Teilschaltung auch der Typ des Filterelements ggf. detektierbar, so beispielsweise in Abhängigkeit von vorgegebenen Widerstandswerten innerhalb der eingeschleiften Teilschaltung.In a preferred embodiment, the filter element loses after insertion into the vacuum cleaner and in a preferred manner according to hereafter initial switch-on the vacuum cleaner its function as part of the electrical circuit, with the result that this filter element is not re-detected in a reuse. Furthermore, by means of the electrical subcircuit provided in the filter element, the type of filter element may also be detectable, for example as a function of predetermined resistance values within the looped-in subcircuit.

In einer bevorzugten Ausgestaltung des Erfindungsgegenstandes ist vorgesehen, dass das Filterelement ein elektrisch leitfähiges Element aufweist, das bei Inbetriebnahme des Staubsaugers, bei im übrigen Teil fest ausgebildeter Schaltung, und bestimmungsgemäßer Bestromung der Schaltung nach Art einer elektrischen Sicherung seine Leitfähigkeit verliert. Es kann sich diesbezüglich um ein elektrisches bzw. elektronisches Bauteil handeln, welches durch Einsetzen des neuen Filterelements in den Staubsauger zum Schließen der der Erfassung dienenden elektrischen Schaltung führt. Die außerhalb des Filterelements vorgesehene Teilschaltung ist fester Bestandteil des Staubsaugers und steht in elektronischem Kontakt zu einer Elektronik, die beispielsweise den Gebrauchszähler auf Null setzt und/oder eine Fehlermeldung bei Weiterverwendung desselben Filterelements auslöst. Dieses an bzw. in dem Filterelement vorgesehene elektrisch leitfähige Element führt zu einem kurzzeitigen Schließen des Erfassungs-Stromkreises. Mittels des hierbei in üblicher Höhe durch die Schaltung fließenden Stromes wird die Leitfähigkeit des filterelementseitigen Elements aufgehoben. Der Schaltkreis ist hiernach unterbrochen. Entsprechend führt das Einsetzen eines neuen Filterelements lediglich zu einem impulsartigen Schalten infolge der Stromkreisschließung mittels des Filterelements. Das den Gebrauchszähler auf Null setzende und eine Fehlermeldung unterbindende elektrische Element des neuen Filters wird unmittelbar nach dessen Erfassung so beeinflusst, dass der Stromkreis wieder unterbrochen ist.In a preferred embodiment of the subject invention, it is provided that the filter element has an electrically conductive element, which loses its conductivity at startup of the vacuum cleaner, in the remaining part fixed circuit, and intended energization of the circuit in the manner of an electrical fuse. It may in this regard be an electrical or electronic component, which leads by closing the new filter element in the vacuum cleaner for closing the detection serving electrical circuit. The provided outside of the filter element subcircuit is an integral part of the vacuum cleaner and is in electronic contact with an electronics, for example, sets the utility counter to zero and / or triggers an error message on further use of the same filter element. This provided on or in the filter element electrically conductive element leads to a brief closure of the detection circuit. By means of this in the usual amount flowing through the circuit current, the conductivity of the filter element-side element is canceled. The circuit is interrupted thereafter. Accordingly, the insertion of a new filter element merely results in a pulse-like switching due to the circuit closing by means of the filter element. This sets the usage counter to zero and suppresses an error message electrical element of the new filter is influenced immediately after its detection so that the circuit is interrupted again.

In Abhängigkeit vom Schließen des Stromkreises infolge eines intakten elektrisch leitfähigen Elements in dem Filterelement kann beispielsweise ein mechanisches Element so verlagert werden, dass das filterseitige Element zerstört, beispielsweise getrennt wird. Eine insbesondere herstellungsgünstige Lösung ist dadurch erreicht, dass das leitfähige Element durch Schmelzen elektrisch getrennt wird. Entsprechend ist das leitfähige Element so ausgelegt, dass dieses bei bestimmungsgemäßer Bestromung infolge eines Erst-Einschaltens des Staubsaugers in kürzester Zeit, bevorzugt innerhalb eines Teils einer Sekunde durchbrennt. Die kurzzeitige Leitfähigkeit vor einem Schmelzen reicht als Impuls für eine geräteseitige Elektronik zur Rückstellung des Gebrauchszählers auf Null bzw. zur Unterbindung einer Fehlermeldung aus.Depending on the closing of the circuit due to an intact electrically conductive element in the filter element, for example, a mechanical element can be displaced so that the filter-side element is destroyed, for example, separated. A particularly low-production solution is achieved in that the conductive element is electrically separated by melting. Accordingly, the conductive element is designed so that it burns during normal energization as a result of a first switching on the vacuum cleaner in a very short time, preferably within a part of a second. The short-term conductivity before melting is sufficient as a pulse for a device-side electronics for resetting the utility counter to zero or to prevent an error message.

Die Erfindung betrifft des weiteren ein in einem Elektro-Staubsauger einzusetzendes Filterelement, beispielsweise Filterbeutel oder kastenartiger Feinstfilter.The invention further relates to a filter element to be used in an electric vacuum cleaner, for example a filter bag or a box-type superfine filter.

Um ein Filterelement der in Rede stehenden Art in gebrauchsvorteilhafter Weise weiterzubilden, wird ein elektrisch leitfähiges Element vorgeschlagen, das beim Einsetzen des Filterelements in den Staubsauger Teil einer sich unter Ergänzung durch staubsaugerfeste Komponenten ergebenden elektrischen Schaltung sein kann, wobei das elektrisch leitfähige Element bei bestimmungsgemäßer Bestromung in Art einer Sicherung in einen nicht leitfähigen Zustand übergeht. Infolge dieser Ausgestaltung ist mittels eines solchen Filterelements in Zusammenhang mit einem entsprechend ausgebildeten Staubsauger eine Wiederverwendung eines gebrauchten Filterelements gegebenenfalls unterbindbar, so weiter jedenfalls in Form einer Fehlermeldung anzeigbar. Zudem kann mittels des leitfähigen Elements bei entsprechender Ausbildung des Staubsaugers ein Gebrauchszähler oder dergleichen auf Null gesetzt werden, sofern ein neuer Filter eingesetzt wurde. Nach Einsetzen eines neuen, das elektrisch leitfähige Element aufweisenden Filterelements in den Staubsauger und anschließendem Erst-Einschalten desselben verliert das elektrisch leitfähige Element des Filters bei bestimmungsgemäßer Bestromung der Gesamtschaltung seine Leitfähigkeit, wonach der Filter als bereits einmal eingesetzt und in den Stromkreis eingebunden gekennzeichnet wird.In order to develop a filter element of the type in question in nutzsvorteilhafter way, an electrically conductive element is proposed, which may be part of a resulting from supplementation by Staubsaugerfeste components electrical circuit when inserting the filter element in the vacuum cleaner, wherein the electrically conductive element under normal energization in the manner of a fuse changes into a non-conductive state. As a result of this configuration, a reuse of a used filter element can optionally be prevented by means of such a filter element in connection with a suitably designed vacuum cleaner, so on, at least in the form of an error message displayable. In addition, by means of the conductive element with appropriate design of the vacuum cleaner, a utility counter or the like can be set to zero, if a new Filter was used. After inserting a new, the electrically conductive element having filter element in the vacuum cleaner and subsequent initial switching of the same loses the electrically conductive element of the filter in accordance with the intended energization of the overall circuit its conductivity, after which the filter is already used as already inserted and integrated into the circuit.

Dargestellt und beschrieben ist zunächst mit Bezug zu Figur 1 ein Elektro-Staubsauger 1 in Form eines Handstaubsaugers mit einem Grundgehäuse 2, einer an diesem abschwenkbar gehalterten, einen ein erstes Filterelement E bildenden Filterbeutel 3 aufnehmenden Filterkammer 4, sowie einem Gerätestiel 5 und einem Saug-Vorsatzgerät 6.Shown and described is first with reference to FIG. 1 an electric vacuum cleaner 1 in the form of a hand-held vacuum cleaner with a base housing 2, a abgeschwenkbar held on this, a first filter element E forming filter bag 3 receiving filter chamber 4, and a device handle 5 and a suction attachment. 6

Der Filterbeutel 3 weist eine Halteplatte 7 auf, mit einer Öffnung 8, durch welche mittels des aufzubringenden Saugluftstromes Schmutz-/Staubpartikel in den Filterbeutel 3 transportiert werden.The filter bag 3 has a holding plate 7, with an opening 8 through which dirt / dust particles are transported into the filter bag 3 by means of the suction air flow to be applied.

Unterseitig der Halteplatte 7 ist der luftdurchlässige, sackartige Beutel 9 befestigt, unter Belassung eines umlaufenden freien Halteplattenrandes 10.On the underside of the holding plate 7, the air-permeable, bag-like bag 9 is fixed, leaving a circumferential free holding plate edge 10th

Mittels dieses Halteplattenrandes 10 stützt sich der Filterbeutel 3 an einer zugeordneten Stirnrandkante 11 der Filterkammer 4 ab unter klemmendem Einschluss des Halteplattenrandes 10 durch eine mit der Stirnrandkante 11 der Filterkammer korrespondierenden Randkante 12 des Grundgehäuses 2.By means of this holding plate edge 10, the filter bag 3 is supported on an associated end edge 11 of the filter chamber 4 under clamping inclusion of the holding plate edge 10 by a corresponding with the end edge 11 of the filter chamber edge 12 of the base housing. 2

In einem Teilabschnitt des Halteplattenrandes 10, in dem Ausführungsbeispiel mittig einer Längsrandkante, ist unterseitig, in Einbausituation entsprechend der Stirnrandkante 11 der Filterkammer 4 zugewandt, ein elektrisch leitfähiges Element 13 vorgesehen. Dieses ist vollflächig mit dem Halteplattenmaterial verbunden, so beispielsweise mit diesem verklebt und in einfachster Weise in Form einer elektrischen Leiterbahn ausgebildet, mit zwei freien Enden.In a partial section of the retaining plate edge 10, in the exemplary embodiment in the middle of a longitudinal edge, an electrically conductive element 13 is provided on the underside, in the installation situation corresponding to the end edge 11 of the filter chamber 4 facing. This is the entire surface connected to the holding plate material, for example glued to this and formed in the simplest manner in the form of an electrical conductor, with two free ends.

Diese beiden freien Enden des elektrischen Elements 13 werden in Einbausituation gemäß der Darstellung in Figur 3 staubsaugerseitig kontaktiert durch entsprechend positionierte Kontaktfahnen 14. Diese stehen in Einbausituation in elektrischem Kontakt zu dem elektrischen Element 13 und bilden die freien Enden einer geräteseitig fest ausgebildeten Schaltung S.These two free ends of the electrical element 13 are in the installation situation as shown in FIG FIG. 3 Vacuum cleaner side contacted by appropriately positioned tabs 14. These are in the installation situation in electrical contact with the electrical element 13 and form the free ends of a device side fixed circuit S.

Nach Einbau eines neuen Filterelements E, das heißt in dem ersten Ausführungsbeispiel eines neuen Filterbeutels 3, mit intaktem elektrischen Element 13, wird auf der mit Info bezeichneten Leitung das Potential VB gemessen. Ein Mikrocontroller 15 detektiert hieraus das neu eingesetzte Filterelement E. Entsprechend wird über eine Leitung Zo ein nicht dargestellter Gebrauchszähler auf Null gesetzt.After installation of a new filter element E, that is, in the first embodiment of a new filter bag 3, with intact electrical element 13, the potential V B is measured on the line indicated by Info. A microcontroller 15 detects from this the newly inserted filter element E. Accordingly, a non-illustrated utility counter is set to zero via a line Zo.

Unmittelbar nach der Detektierung des neuen Filterelements E, was innerhalb eines Bruchteils einer Sekunde erfolgt, wird das elektrische Element 13 zerstört, so infolge eines Schmelzens der Leiterbahn infolge bestimmungsgemäßer Bestromung der gesamten Schaltung. Die Leiterbahn ist hierzu mit einer entsprechend geringen Stärke bzw. Breite versehen. Die Schmelzstelle kann vordefiniert sein, so bspw. durch eine taillenartige Einschnürung und/oder durch kontaktfreies Freilegen eines Leiterbahnabschnitts.Immediately after the detection of the new filter element E, which takes place within a fraction of a second, the electrical element 13 is destroyed, as a result of melting of the conductor as a result of intended energization of the entire circuit. The conductor is provided for this purpose with a correspondingly low thickness or width. The melting point can be predefined, for example by a waist-like constriction and / or by contact-free exposure of a conductor track section.

Die galvanische Trennung bewirkt, dass infolge dessen auf der Info-Leitung nunmehr das Potential VA gemessen wird.As a result of this, galvanic isolation causes the potential V A to be measured on the info line.

Nach Erreichen einer maximalen Betriebsstundenzahl und/oder im Zuge des Öffnens des das Filterelement E aufnehmenden Gehäuses wird die Schaltung S in einen Zustand versetzt, in welchem eine Überwachung des Filterelementschaltkreises erfolgt. Wird in diesem Zustand ein gebrauchtes Filterelement E mit zerstörtem elektrischen Element wieder eingesetzt, so führt dies entsprechend nicht zu einer Detektierung der Spannung VB. Der Mikroprozessor 15 übersetzt nach einem Schließen des das Filterelement E aufnehmenden Gehäuses dies als Fehler, zufolge dessen der Betriebsstundenzähler nicht auf Null zurückgesetzt wird. Vielmehr wird über eine weitere Leitung F eine Fehlermeldung ausgelöst, so beispielsweise eine optische oder akustische Fehlermeldung, die dem Benutzer den nicht ordnungsgemäßen Einsatz eines Filterelements E vermittelt. Entsprechend wird auch ein Nichteinsetzen eines Filterelements E erfasst.After reaching a maximum number of operating hours and / or in the course of opening the filter element E receiving housing, the circuit S is placed in a state in which a monitoring of the filter element circuit takes place. If a used filter element E with destroyed electrical element is used again in this state, this does not correspondingly result in a detection of the voltage V B. The microprocessor 15, after closing the housing housing the filter element E, translates this as a fault, according to which the operating hours counter is not reset to zero. Rather, an error message is triggered via a further line F, such as a visual or audible error message that the user the improper use of a filter element e taught. Accordingly, a non-insertion of a filter element E is detected.

Erst der Einsatz eines neuen, ein intaktes elektrisches Element aufweisenden Filterelements E führt zu einem Reset der Schaltung S.Only the use of a new, an intact electrical element having filter element E leads to a reset of the circuit S.

In Figur 6 ist das Filterelement E in Form eines Feinstfilters 16 dargestellt. Dieses weist ein kastenartiges Gehäuse 17 auf, in welchem Filtermaterial 18 in ZickZack-Form eingelegt ist.In FIG. 6 the filter element E is shown in the form of a superfine filter 16. This has a box-like housing 17 in which filter material 18 is inserted in zigzag form.

An einer Seitenfläche des Gehäuses 17 ist außenwandig das elektrische Element 13 in Form einer schlangenlinienartig aufgebrachten Leiterbahn vorgesehen, mit endseitigen Kontaktstellen 19, die in Gebrauchsstellung mit geräteseitigen Kontaktfahnen in elektrischer Verbindung stehen. Auch dieses elektrische Element 13 ist so ausgelegt, dass bei bestimmungsgemäßer Bestromung, das heißt bei einer üblichen, für die Schaltung S geeigneten Bestromung diese schmilzt und somit ihre elektrische Leitfähigkeit verliert.On a side surface of the housing 17, the electrical element 13 is externally provided in the form of a serpentine applied conductor track, with end-side contact points 19, which are in use position with device-side tabs in electrical connection. Also, this electrical element 13 is designed so that when properly energized, that is, in a conventional, suitable for the circuit S energizing them melts and thus loses its electrical conductivity.

Claims (4)

  1. An electrical vacuum cleaner (1) with a device for detecting whether an inserted filter element (E) is new and optionally whether it is formed in a particular manner, the detecting being effected by virtue of an electrical switch (S), the filter element (E) being, at least initially, part of the electrical switch (S), and, in this condition, a usage counter being set to zero and/or an error signal being triggered, in dependence on the housing accommodating the filter (E) being opened, in the event of the same filter element being used again.
  2. An electrical vacuum cleaner according to Claim 1, characterized in that the filter element (E) has an electrically conductive element (13), which, in the case of a switch (S) which is otherwise solid state, when the vacuum cleaner (1) is started-up and and the switch is energized with the rated current, loses its conductivity in the manner of an electrical fuse.
  3. An electrical vacuum cleaner according to Claim 2, characterized in that conductive element (13) is electrically severed by melting.
  4. A filter element (E) insertable into an electrical vacuum cleaner (1), in particular a filter bag (3) or a box-form fine filter (16), characterized by an electrically conductive element (13), which, when the filter element (E) is inserted into the vacuum cleaner (1), can be part of an electrical switch (S), which is provided in conjunction with components fixed to the vacuum cleaner, the electrically conductive element (13) changing to a non-conductive state, in the manner of a fuse, in the presence of the rated current.
