Description

Sicherungsvorrichtung für ein Filterelement Safety device for a filter element
Die vorliegende Erfindung betrifft eine Sicherungsvorrichtung für ein Filterelement, das an einer Dunstabzugshaube lösbar montierbar ist.The present invention relates to a securing device for a filter element, which can be detachably mounted on an extractor hood.
Dunstabzugshauben sind mit abnehmbaren Filtern, insbesondere Fettfiltem versehen, um das Reinigen und/oder das Wechseln des Filters zu ermöglichen. Die Filterelemente sind über eine Befestigungseinrichtung, beispielsweise eine Verriegelungseinrichtung oder eine Bolzenverbindung, in der Absaugöffnung einer Dunstabzugshaube befestigbar. Das Lösen der Befestigungseinrichtung des Filterelements wird in der Regel in der Gebrauchsanweisung erklärt. Da der Filter in relativ großen Abständen (ca. 4-8 Wochen) ausgetauscht bzw. gereinigt werden muß, besteht die Gefahr, daß der Benutzer die Hinweise zum Ausbauen des Filterelements vergessen hat und die Gebrauchsanweisung nicht benutzt, so daß das Filterelement unter Umständen unsachgemäß ausgebaut wird. Im schlimmsten Fall kann dies dazu führen, daß das Filterelement während der Demontage von der Dunstabzugshaube auf die darunter befindliche Kochstelle herabfallen kann. Dabei kann einerseits das Filterelement selbst beschädigt oder zerstört werden, andererseits kann die Kochstelle, wie zum Beispiel ein Glaskeramikkochfeld beschädigt oder zerstört werden.Extractor hoods are equipped with removable filters, especially grease filters, to enable cleaning and / or changing the filter. The filter elements can be fastened in the suction opening of an extractor hood via a fastening device, for example a locking device or a bolt connection. The loosening of the fastening device of the filter element is usually explained in the instructions for use. Since the filter has to be replaced or cleaned at relatively large intervals (approx. 4-8 weeks), there is a risk that the user has forgotten the instructions for removing the filter element and has not used the instructions for use, so that the filter element may be improper is expanded. In the worst case, this can lead to the filter element falling down from the extractor hood onto the hob underneath during dismantling. On the one hand, the filter element itself can be damaged or destroyed, on the other hand, the hotplate, such as a glass ceramic hob, can be damaged or destroyed.
Es ist bekannt, in der Absaugöffnung einer Dunstabzugshaube eine Kette zu befestigen, deren freies Ende über einen Karabinerhaken verfügt, um daran das Filterelement zu befestigen. Bei einer unsachgemäßen Demontage des Filterelements wird daher das Filterelement mittels der Kette aufgefangen. Nachteilig an dieser Sicherungsvorrichtung ist der Umstand, daß die Kette und der Karabinerhaken im Betrieb der Dunstabzugshaube, angeregt durch den Ventilator ein unangenehmes Geräusch, wie zum Beispiel Rasseln oder Klappern verursacht. Weiterhin ist eine derartige Vorrichtung sehr aufwendig, da sowohl am Filterelement als auch in der Dunstabzugshaube eine Öse vorgesehen werden muß, um die Kette bzw. den Karabinerhaken daran jeweils zu befestigen. Aufgabe der vorliegenden Erfindung ist es daher, eine Sicherungsvorrichtung für ein Filterelement, das an einer Dunstabzugshaube lösbar montiert ist, vorzusehen, die einfach aufgebaut, geräuscharm, benutzerfreundlich und betriebssicher ist.It is known to attach a chain in the suction opening of an extractor hood, the free end of which has a snap hook in order to attach the filter element to it. In the event of improper disassembly of the filter element, the filter element is therefore caught by means of the chain. A disadvantage of this securing device is the fact that the chain and the snap hook in operation of the extractor hood, caused by the fan, causes an unpleasant noise, such as rattling or rattling. Furthermore, such a device is very complex, since an eyelet must be provided both on the filter element and in the extractor hood in order to attach the chain or the snap hook to it in each case. The object of the present invention is therefore to provide a securing device for a filter element which is detachably mounted on an extractor hood, which is simple in construction, low in noise, user-friendly and reliable in operation.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is solved by the features of claim 1. Advantageous refinements and developments of the invention result from the subclaims.
Die Sicherungsvorrichtung für ein Filterelement, das an einer Dunstabzugshaube lösbar montierbar ist, hat eine Verbindungseinrichtung zum lösbaren Verbinden des Filterelements mit der zugehörigen Dunstabzugshaube, wobei die Verbindungseinrichtung das Filterelement beim Demontieren von der Dunstabzugshaube auffängt und gegen Herabfallen sichert. Indem die Verbindungseinrichtung ein Befestigungselement mit einem stabartigen Abschnitt und einer daran anschließenden Verdickung und ein Verschlußelement mit einem U-förmigen Schlitz hat, wobei der stabartige Abschnitt des Befestigungselements passend zur U-förmigen Schlitz des Verschlußelements ausgebildet ist, wird eine sehr einfache und leicht zu handhabende Verbindungseinrichtung zur Verfügung gestellt, da zum Verbinden lediglich das Befestigungselement mit seinem stabartigen Abschnitt in den U-förmigen Schlitz des Verschlußelements eingeführt werden muß.The securing device for a filter element, which can be detachably mounted on an extractor hood, has a connecting device for releasably connecting the filter element to the associated extractor hood, the connecting device catching the filter element when it is removed from the extractor hood and securing it against falling. In that the connecting device has a fastening element with a rod-like section and an adjoining thickening and a closure element with a U-shaped slot, the rod-like section of the fastening element being designed to match the U-shaped slot of the closure element, a very simple and easy to use Connection device provided, since only the fastening element with its rod-like section has to be inserted into the U-shaped slot of the closure element for connection.
Indem der stabartige Abschnitt des Befestigungselements passend zur U-förmigen Schlitz des Verschlußelements ausgebildet ist, wird einerseits eine sichere Verbindung bereitgestellt , die sich nicht lockern kann, andererseits werden Relativbewegungen zwischen den Teilen vermieden, so dass keine Vibrationsgeräusche entstehen können.Because the rod-like section of the fastening element is designed to match the U-shaped slot of the closure element, on the one hand a secure connection is provided that cannot loosen, and on the other hand relative movements between the parts are avoided, so that no vibration noises can occur.
In einer vorteilhaften Ausführung hat die Verbindungseinrichtung ein Band, wobei das eine Ende des Bandes entweder am Filterelement oder an der Dunstabzugshaube befestigt ist und das andere Ende des Bandes entweder mit dem Befestigungselement oder dem Verschlußelement versehen ist, wobei das jeweilige Gegenstück entweder das Verschlußelement oder das Befestigungselement entweder am Filterelement oder an der Dunstabzugshaube befestigt ist. Hier durch ist es möglich, den U-förmigen Schlitz des Befestigungselements auf einfache Weise entweder integral am Gehäuse der Dunstabzugshaube oder integral am Filterelement auszubilden. Damit wird eine sehr einfach aufgebaute Verbindungseinrichtung zur Verfügung gestellt.In an advantageous embodiment, the connecting device has a band, one end of the band being attached either to the filter element or to the extractor hood and the other end of the band being provided with either the fastening element or the closure element, the respective counterpart either the closure element or the Fastening element is attached either to the filter element or to the extractor hood. Here, it is possible to easily integrate the U-shaped slot of the fastener either integrally on the housing Extractor hood or integral on the filter element. This provides a very simply constructed connection device.
In einer vorteilhaften Ausführung ist das Band aus einem elastischen Material, bevorzugt Kunststoff, insbesondere einem verformungsfähigen Thermoplasten hergestellt. Indem ein elastisches Material für das Band vorgesehen wird, wird einerseits ein herabstürzendes Filterelement weich aufgefangen, andererseits hat ein elastisches Material eine sehr hohe Eigendämpfung, so dass eine Vibrationsanregung durch den Ventilator unterdrückt wird und somit eine Geräuschentwicklung verhindert wird.In an advantageous embodiment, the band is made of an elastic material, preferably plastic, in particular a deformable thermoplastic. By providing an elastic material for the belt, on the one hand a falling filter element is softly collected, on the other hand an elastic material has a very high internal damping, so that vibration excitation by the fan is suppressed and noise is prevented.
In einer vorteilhaften Ausführung ist die Länge des Bandes derart vorbestimmt, dass das am Band herabhängende Filterelement eine darunter befindliche Kochstelle nicht berührt. Für den Fall, dass ein Filterelement beim Austauschen oder Wechseln abstürzt, wird dadurch insbesondere auch die darunter befindliche Kochstelle vor Beschädigung geschützt,.In an advantageous embodiment, the length of the belt is predetermined in such a way that the filter element hanging on the belt does not touch a hotplate located underneath. In the event that a filter element crashes when exchanging or replacing, this also protects the hotplate underneath from damage.
In einer vorteilhaften Ausführung ist das Band mit einer Signalfarbe versehen, so dass der Benutzer der Dunstabzugshaube beim Wiedereinbau des Filterelements die Verbindungseinrichtung nicht übersehen kann, und daran erinnert wird, das Befestigungselement in das Verschlußelement einzuführen.In an advantageous embodiment, the band is provided with a signal color, so that the user of the extractor hood cannot overlook the connection device when the filter element is reinstalled, and is reminded to insert the fastening element into the closure element.
In einer vorteilhaften Ausführung hat der U-förmige Schlitz des Befestigungselements eine Verengung an seiner Öffnung. Hierdurch ist es möglich, das Befestigungselement mit seinem stabartigen Abschnitt sicher in montiertem Zustand zu halten.In an advantageous embodiment, the U-shaped slot of the fastening element has a constriction at its opening. This makes it possible to hold the fastener with its rod-like section securely in the assembled state.
In einer vorteilhaften Ausführung ist der U-förmige Schlitz in einem Blechabschnitt des Filterelements oder der Dunstabzugshaube ausgebildet. Hierdurch kann das Verschlußelement auf besonders einfache Weise hergestellt werden.In an advantageous embodiment, the U-shaped slot is formed in a sheet metal section of the filter element or the extractor hood. As a result, the closure element can be produced in a particularly simple manner.
In einer vorteilhaften Ausführung schließt sich an die Öffnung des U-förmigen Schlitzes eine große Öffnung zum Einführen der Verdickung des Befestigungselements an und ist damit schlüssellochförmig ausgebildet, und die Verdickung ist kugelförmig ausgebildet. Durch diese Gestaltung ist ein einfaches Verbinden des Befestigungselement mit dem Verschlußelement gewährleistet. Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispiels einer erfindungsgemäßen Sicherungsvorrichtung für ein Filterelement an einer Dunstabzugshaube unter Bezugnahme auf die Zeichnungen.In an advantageous embodiment, the opening of the U-shaped slot is adjoined by a large opening for introducing the thickening of the fastening element and is thus keyhole-shaped, and the thickening is spherical. This design ensures a simple connection of the fastening element to the closure element. Further details, features and advantages of the invention result from the following description of an exemplary embodiment of a securing device according to the invention for a filter element on an extractor hood with reference to the drawings.

Das Verschlußelement 11 ist als eine schlüssellochförmige Öffnung 14 integral in einem Blech oder einer Lasche des Gehäuses 2 der Dunstabzugshaube 1 ausgebildet. Die schlüssellochflörmige Öffnung 14 hat eine große Öffnung 15 und einen sich daran anschließenden U-förmigen Schlitz 16. Die große Öffnung 15 ist derart dimensioniert, dass die Verdickung 13 hindurch paßt. Der U-förmige Schlitz 16 ist in seiner Breitenerstreckung derart bemessen, dass der stabartige Abschnitt 12 benachbart zur Verdickung 13 enganliegend paßt. Der U-förmige Schlitz 16 hat im Übergangsbereich zur großen Öffnung 15 eine Verengung 17.2, the filter element 3 has a frame 6 with a tab 7 attached to the frame 6. In FIG. 2, the housing 2 of the extractor hood 1 is only shown as a small section of a sheet metal part inside the housing 2. The securing device 4 is designed as a connecting device 8, which comprises a band 9, a fastening element 10 and a closure element 11. The band 9 is fastened with its one end side to the tab 7 of the filter element 3 and on its other end side it is provided with the fastening element 10, which comprises a rod-like section 12 and a thickening 13 adjoining it. In the present case, the rod-like section 12 is formed integrally with the band 9. The closure element 11 is formed as a keyhole-shaped opening 14 integrally in a sheet or a tab of the housing 2 of the extractor hood 1. The keyhole-shaped opening 14 has a large opening 15 and an adjoining U-shaped slot 16. The large opening 15 is dimensioned such that the thickening 13 fits through. The width of the U-shaped slot 16 is dimensioned such that the rod-like section 12 fits closely to the thickening 13. The U-shaped slot 16 has a constriction 17 in the transition area to the large opening 15.
Das Band ist bevorzugt aus einem elastischen Material, insbesondere Kunststoff bzw. einem verformungsfähigen Thermoplasten hergestellt. Die Länge des Bandes 9 ist derart ausgelegt, dass das am Band herabhängende Filterelement 3 eine darunterbefindliche Kochstelle (nicht dargestellt) nicht berühren kann. Die Verdickung 13 ist bevorzugt kugelförmig ausgebildet.The band is preferably made of an elastic material, in particular plastic or a deformable thermoplastic. The length of the belt 9 is designed in such a way that the filter element 3 hanging on the belt cannot touch a hotplate (not shown) located underneath. The thickening 13 is preferably spherical.
Zur Montage der Verbindungseinrichtung 8 wird das Band 9 mit der daran ausgebildeten Verdickung 13 durch die große Öffnung 15 der schlüssellochförmigen Öffnung 14 eingeführt und dann mit seinem stabartigen Abschnitt 12 gegen die Verengung 17 in den U-förmigen Schlitz 16 eingeführt. Die Demontage der Verbindungseinrichtung 8 erfolgt in entgegengesetzter Reihenfolge.To assemble the connecting device 8, the band 9 with the thickening 13 formed thereon is inserted through the large opening 15 of the keyhole-shaped opening 14 and then inserted with its rod-like section 12 against the constriction 17 into the U-shaped slot 16.
