Description

Die vorliegende Erfindung betrifft eine Dunstabzugshaube mit einem lösbar an derselben montierbaren Filterelement und einer Sicherungsvorrichtung.The present invention relates to an extractor hood with a releasably attachable to the same filter element and a securing device.

Dunstabzugshauben sind mit abnehmbaren Filtern, insbesondere Fettfiltern versehen, um das Reinigen und/oder das Wechseln des Filtereinsatzes zu ermöglichen. Die Filterelemente sind über eine Befestigungseinrichtung, wie eine Verriegelungseinrichtung oder dergleichen 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 bis 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 Kochstelle herabfallen kann. Dabei kann einerseits das Filterelement selbst beschädigt oder zerstört werden und andererseits kann die Kochstelle, wie z.B. ein Glaskeramikkochfeld beschädigt oder zerstört werden.Cooker hoods are equipped with removable filters, especially grease filters, to allow cleaning and / or changing the filter element. The filter elements can be attached via a fastening device, such as a locking device or the like in the suction opening of a cooker hood. The release of the fastening device of the filter element is usually explained in the instructions for use. Since the filter must be replaced or cleaned at relatively large intervals (about 4 to 8 weeks), there is a risk that the user has forgotten the instructions for removing the filter element and the instructions for use not used, so that the filter element may improperly is expanded. In the worst case, this may result in the filter element falling from the cooker hood to the cooking surface during disassembly. In this case, on the one hand the filter element itself can be damaged or destroyed and on the other hand, the hotplate, such. a glass ceramic hob is damaged or destroyed.

Es ist bekannt, in der Absaugöffnung der 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 der Benutzer bei der Montage des Filterelements in der Absaugöffnung der Dunstabzugshaube bewusst oder unbewusst die Kette nicht mehr einhängt.It is known to attach in the suction opening of the hood a chain whose free end has a snap hook to attach the filter element. In an improper disassembly of the filter element, therefore, the filter element is collected by means of the chain. A disadvantage of this securing device is the fact that the user consciously or unconsciously no longer hangs up the chain during assembly of the filter element in the suction opening of the extractor hood.

Das Dokument FR-A-2423255 zeigt eine Sicherungsvorrichtung mit den Merkmalen der Praämbel des Anspruchs 1.Document FR-A-2423255 shows a securing device having the features of the preamble of claim 1.

Aufgabe der vorliegenden Erfindung ist es daher, eine Dunstabzugshaube mit einem lösbar an derselben montierbaren Filterelement und einer Sicherungsvorrichtung vorzusehen, die betriebssicher, benutzerfreundlich und einfach aufgebaut ist.Object of the present invention is therefore to provide a cooker hood with a releasably attachable to the same filter element and a securing device that is reliable, user-friendly and simple.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This object is solved by the features of patent claim 1.

In einer vorteilhaften Ausführung sind der Anlenkpunkt des Verbindungselements mit der Dunstabzugshaube gegenüber dem Befestigungspunkt des Verbindungselements mit dem Filterelement in montiertem Zustand des Filterelements an der Dunstabzugshaube zueinander derart versetzt, dass der steife Körper des Verbindungselements eine Schräglage einnimmt, wobei das am Filterelement befestigte Verbindungselement die Monatage des Filterelements der Absaugöffnung nicht behindert, so dass eine leichte Montage des Filterelements in der Absaugöffnung der Dunstabzugshaube möglich ist.In an advantageous embodiment, the articulation point of the connecting element with the extractor hood with respect to the attachment point of the connecting element with the filter element in the assembled state of the filter element to the hood are offset from each other such that the rigid body of the connecting element occupies an inclined position, wherein the fastening element attached to the filter element the Monatage the filter element of the suction opening is not hindered, so that an easy mounting of the filter element in the suction opening of the extractor hood is possible.

In einer vorteilhaften Ausführung ist der Befestigungspunkt zwischen Verbindungselement und Filterelement entlang einer Längsführung verschiebbar. Somit kann einerseits bei der Demontage des Filterelements das Filterelement tiefer abgehängt werden, wobei die Zugänglichkeit zum Verbindungselement und damit zum Lösen des Verbindungselements verbessert wird. Andererseits wird die Montage des Filterelements in der Absaugöffnung der Dunstabzugshaube erleichtert, da durch die Längsführung das Filterelement gegenüber der Absaugöffnung in einem größeren Bereich beweglich ist.In an advantageous embodiment of the attachment point between the connecting element and filter element along a longitudinal guide is displaceable. Thus, on the one hand during disassembly of the filter element, the filter element can be suspended lower, the accessibility to the connecting element and thus for releasing the connecting element is improved. On the other hand, the assembly of the filter element in the suction opening of the extractor hood is facilitated because the filter element is movable in a larger area relative to the suction opening by the longitudinal guide.

In einer vorteilhaften Ausführung ist die Längsführung als ein hintergreifbarer Steg ausgebildet, der parallel zur Ebene des Filterelements am Filterelement vorgesehen ist, wobei eine besonders einfache Längsführung zur Verfügung gestellt wird.In an advantageous embodiment, the longitudinal guide is formed as a tangible behind web, which is provided parallel to the plane of the filter element on the filter element, with a particularly simple longitudinal guide is provided.

In einer vorteilhaften Ausführung ist an der unteren Endseite des steifen Körpers eine Hakeneinrichtung zum lösbaren Befestigen des Filterelements vorgesehen, wodurch das Verbindungselement auf einfache Weise am Filterelement montiert und demontiert werden kann.In an advantageous embodiment, a hook means for releasably securing the filter element is provided on the lower end side of the rigid body, whereby the connecting element can be easily mounted on the filter element and disassembled.

In einer vorteilhaften Ausführung ist die Hakeneinrichtung als eine zangenförmige Feder ausgebildet, die mit dem Steg in Eingriff bringbar ist, wodurch eine sichere Verbindung zwischen dem Verbindungselement und dem Filterelement zur Verfügung gestellt wird. Indem die zangenförmige Feder einen Griffabschnitt zum Öffnen der zangenförmigen Feder hat, kann die zangenförmige Feder auf einfache Weise durch einen Benutzer betätigt werden.In an advantageous embodiment, the hook device is designed as a pincer-shaped spring, which can be brought into engagement with the web, whereby a secure connection between the connecting element and the filter element is provided. By the forceps-shaped spring having a handle portion for opening the forceps-shaped spring, the forceps-shaped spring can be easily operated by a user.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehen Beschreibung eines Ausführungsbeispiels einer erfindungsgemäßen Dunstabzugshaube unter Bezugnahme auf die Zeichnungen.Further details, features and advantages of the invention will become apparent from the following description of an embodiment of an extractor hood according to the invention with reference to the drawings.

Der Filter 10 kann aus einem waschbaren Vliesmaterial oder einem Streckmetall oder Ähnlichem hergestellt sein, das insbesondere zur Abscheidung von Fett geeignet ist. An zwei gegenüber liegenden Seiten des Filterelements 4 ist je eine Verriegelungseinrichtung 11 (siehe auch Fig. 3) vorgesehen, die dazu dient, das in die Absaugöffnung 2 der Dunstabzugshaube 3 eingesetzte Filterelement 4 mit der Dunstabzugshaube zu verriegeln. Die Verriegelungseinrichtung 11 hat dazu gemäß Fig. 3 eine verriegelte und eine entriegelte Stellung.The extractor hood 3 has an inner rear portion of a lamp housing 7. The filter element 4 has at its rear portion a recess 8 which is closed with a transparent material, such as glass or Plexiglas. In a middle section of the expansion 8, a web 9 extending from the rear to the front is formed. In a front portion of the filter element 4, a replaceable filter 10 is used, are sucked through the vapors and fumes, which rise from an underlying hotplate. The filter 10 may be made of a washable nonwoven material or an expanded metal or the like, which is particularly suitable for the deposition of grease. On two opposite sides of the filter element 4 is ever a locking device 11 (see also Fig. 3) is provided, which serves to the inserted into the suction opening 2 of the hood 3 Lock filter element 4 with the extractor hood. The locking device 11 has, according to FIG. 3, a locked and an unlocked position.

Gemäß Fig. 4, 5 und 6 ist die als Verbindungselement 5 ausgebildete Absturzvorrichtung 1 näher dargestellt. Das Verbindungselement 5 ist als eine Hakeneinrichtung 12 aus einem steifen Federstahldraht hergestellt. Das Verbindungselement 5 hat einen Gelenkabschnitt 13 von dem sich U-förmig zwei Schenkel 14 erstrecken. In einem mittleren Abschnitt der Schenkel 14 ist an jedem Schenkel 14 jeweils eine nach innen gerichtete Biegung vorgesehen, so dass sich die zwei Schenkel 14 kreuzen. Nach dem Kreuzungsabschnitt der Schenkel 14 ist an jedem Schenkel 14 an seinem vorderen Abschnitt ein zu einer Mittellinie 15 hin gerichteter Haken 16 derart ausgebildet, dass die sich gegenüberliegenden Haken 16 eine zangenförmige Feder 17 ausbilden.According to Fig. 4, 5 and 6, designed as a connecting element 5 crash device 1 is shown in more detail. The connecting element 5 is made as a hook device 12 made of a stiff spring steel wire. The connecting element 5 has a hinge portion 13 of the U-shaped two legs 14 extend. In a middle section of the legs 14, in each case an inward bend is provided on each leg 14, so that the two legs 14 intersect. After the crossing portion of the legs 14, a hook 16 directed towards a center line 15 is formed on each leg 14 at its front portion such that the opposing hooks 16 form a pincer-shaped spring 17.

Das Verbindungselement 5 ist mit seinem Gelenkabschnitt 13 mittels einer Öse 18 am Lampengehäuse 7 derart angelenkt, so dass das Verbindungselement 5 nach vorne und hinten verschwenkbar ist. Das Verbindungselement ist mit seinem unteren Abschnitt, der als zangenförmige Feder 17 ausgebildet ist, mit dem Steg 9 des Filterelements 4 verbindbar. Die zangenförmige Feder 17 ist entlang des Stegs beweglich, so dass eine Längsführung 19 entlang des Stegs 9 ausgebildet wird.The connecting element 5 is articulated with its hinge portion 13 by means of an eyelet 18 on the lamp housing 7 such that the connecting element 5 is pivotable forward and backward. The connecting element can be connected to the web 9 of the filter element 4 with its lower portion, which is designed as a pliers-shaped spring 17. The forceps-shaped spring 17 is movable along the web, so that a longitudinal guide 19 is formed along the web 9.

Nachstehend wird der Vorgang der Demontage des Filterelements 4 von der Dunstabzugshaube 3 näher erläutert. Zunächst werden die Verriegelungseinrichtungen 11 von ihrer verriegelten Position in die entriegelte Position verdreht. Das Filterelement 4 ist nun von der Dunstabzugshaube 3 gelöst und nach unten entnehmbar. In diesem Zustand wird das Filterelement 4 mittels des Verbindungselements 5 an der Dunstabzugshaube 3 gehalten, wobei der vordere Abschnitt des Filterelements 4 nach unten hängen kann. Um das Verbindungselement 5 zu lösen, wird gemäß Fig. 2 mit zwei Fingern in Richtung der Pfeile 20 auf die Schenkel 14 des Verbindungselements 5 gedrückt, wobei sich die Haken 16 der zangenförmigen Feder 17 in Richtung des Pfeils 21 öffnen und so die Umschlingung der zangenförmigen Feder 17 gegenüber dem Steg 9 freigibt. Nun ist das Filterelement komplett entnehmbar und kann gereinigt oder getauscht werden.The process of dismantling the filter element 4 from the extractor hood 3 will be explained in more detail. First, the locking devices 11 are rotated from their locked position to the unlocked position. The filter element 4 is now detached from the extractor hood 3 and can be removed downwards. In this state, the filter element 4 is held by means of the connecting element 5 to the extractor hood 3, wherein the front portion of the filter element 4 can hang down. To release the connecting element 5, 2 is pressed with two fingers in the direction of arrows 20 on the legs 14 of the connecting element 5, as shown in FIG. Open with the hooks 16 of the pincer-like spring 17 in the direction of arrow 21 and so the wrap of the pincers Spring 17 relative to the web 9 releases. Now the filter element is completely removable and can be cleaned or replaced.

Zum Montieren des Filterelements 4 an der Dunstabzugshaube 3 muss das Filterelement 4 wieder in die Absaugöffnung 2 der Dunstabzugshaube 3 eingesetzt werden. Dazu muss zunächst das Verbindungselement 5 mit dem Steg 9 wieder verbunden werden. Wird dieser Vorgang unterlassen, so stößt das aus dem festen Drahtkörper bestehende Verbindungselement 5, das über die Absaugöffnung 2 der Dunstabzugshaube 3 nach unter vorsteht, gegen das Filterelement 4, wobei ein korrektes Einsetzen des Filterelements 4 in die Absaugöffnung 2 unterbunden wird. Wird dagegen das Verbindungselement 5 ordnungsgemäß mit dem Steg 9 verbunden, so gleitet die zangenförmige Feder 17 beim Einsetzen des Filterelements 4 entlang des als Längsführung 19 ausgebildeten Stegs 9 nach hinten, so dass bei in der Ansaugöffnung 2 montiertem Filterelement 4 das Verbindungselement 5 eine Schrägstellung einnimmt, wobei der Anlenkpunkt des Verbindungselements 5 mit der Dunstabzugshaube 3 gegenüber einem Befestigungspunkt des Verbindungselements 5 mit dem Filterelement 4 in montiertem Zustand des Filterelements 4 an der Dunstabzugshaube 3 zueinander versetzt sind.For mounting the filter element 4 on the extractor hood 3, the filter element 4 must again be inserted into the suction opening 2 of the extractor hood 3. This must be First, the connecting element 5 are connected to the web 9 again. If this process is omitted, the connecting element 5 consisting of the solid wire body, which protrudes downward beyond the suction opening 2 of the extractor hood 3, abuts against the filter element 4, whereby a correct insertion of the filter element 4 into the suction opening 2 is prevented. If, on the other hand, the connecting element 5 is properly connected to the web 9, then the pliers-shaped spring 17 slides backwards during insertion of the filter element 4 along the web 9 formed as a longitudinal guide 19 so that the connecting element 5 assumes an inclined position when the filter element 4 is mounted in the intake opening 2 , wherein the articulation point of the connecting element 5 with the extractor hood 3 are offset from one another with respect to an attachment point of the connecting element 5 with the filter element 4 in the assembled state of the filter element 4 on the extractor hood 3.

Damit das schräggestellte Verbindungselement 5 nicht gegen das Lampengehäuse 7 stößt, ist in einem mittleren Abschnitt der Schenkel 14 eine Biegung mit einem Winkel α an den Schenkeln 14 ausgebildet (Fig. 6).So that the inclined connecting element 5 does not abut against the lamp housing 7, a bend is formed at an angle α on the legs 14 in a middle section of the legs 14 (FIG. 6).

Die vorstehend beschriebene Sicherungsvorrichtung hat gegenüber einer als Kette ausgebildeten Sicherungsvorrichtung den Vorteil, dass Vibrationen, die durch einen Ventilator angeregt werden, nicht zu Schwingungsgeräuschen führen.The safety device described above has the advantage over a safety device formed as a chain that vibrations that are excited by a fan, do not lead to vibration noises.

Alternativ zu der vorstehend beschriebenen mechanischen Lösung kann eine Montagesperre auch über einen Sensor bewerkstelligt werden, der erkennt, ob das Filterelement über ein Verbindungselement mit der Dunstabzugshaube verbunden ist oder nicht, und mittels einer Steuerungseinrichtung nur dann eine Montage des Filterelements zulässt, wenn das Verbindungselement zwischen Filterelement und Dunstabzugshaube vorgesehen ist.As an alternative to the mechanical solution described above, a mounting lock can also be accomplished via a sensor which detects whether the filter element is connected to the extractor hood via a connecting element or not, and by means of a control device only allows mounting of the filter element when the connecting element between Filter element and hood is provided.
