  • the size of the grease filters is adapted to a certain area of the extractor hood.
  • the grease filters used may not cover the entire filter surface. These tolerances can then result in free spaces or gaps between the individual grease filters. However, this should be avoided. In order to avoid the problem of gap formation, the manufacture of the parts used could be made more precise. However, a lower tolerance causes significantly higher manufacturing costs.
  • the filter device comprises at least one housing device with at least one receiving section for at least two filter devices.

Description

Die vorliegende Erfindung betrifft eine Filtervorrichtung mit wenigstens einer Filterfläche. Die Filtervorrichtung umfasst dabei wenigstens eine Gehäuseeinrichtung mit wenigstens einem Aufnahmeabschnitt für wenigstens zwei Filtereinrichtungen. Dabei wird an dem Aufnahmeabschnitt im eingesetzten Zustand der Filtereinrichtungen die Filterfläche gebildet. Die erfindungsgemäße Filtervorrichtung kann insbesondere als Lüfterbaustein oder eine Dunstabzugshaube ausgeführt sein oder kann wenigstens einen Teil eines Lüfterbausteins oder einer Dunstabzugshaube zur Verfügung stellen.The present invention relates to a filter device with at least one filter surface. The filter device comprises at least one housing device with at least one receiving section for at least two filter devices. In this case, the filter surface is formed on the receiving section in the inserted state of the filter devices. The filter device according to the invention can in particular be designed as a fan module or an extractor hood or can provide at least part of a fan module or an extractor hood.

Über Kochstellen sind häufig Dunstabzugshauben vorgesehen, um die beim Kochen aufsteigenden Kochschwaden abzusaugen. Der aufsteigende Wrasen wird dann insbesondere von Fettbestandteilen befreit, wobei die gereinigte Luft entweder als Abluft aus der Küche abgeführt oder in einem Umluftbetrieb zurück in die Küche geblasen wird. Eine solche Vorrichtung ist beispielsweise aus der Druckschrift DE 10 2008 014 283 A1 und aus der Druckschrift EP 2 469 187 A1 bekannt.Extractor hoods are often provided over hotplates in order to suck off the steam that arises during cooking. The rising vapor is then freed from fat components in particular, the purified air either being discharged from the kitchen as exhaust air or being blown back into the kitchen in a recirculation mode. Such a device is for example from the publication DE 10 2008 014 283 A1 and from the pamphlet EP 2 469 187 A1 known.

Dabei sind in der Regel möglichst große Filterflächen bevorzugt, um eine möglichst gute Filterwirkung bereitzustellen. Dann bilden je nach Aufbau des Gehäuses oft mehrere benachbarte Fettfilter eine gemeinsame Filterfläche. Wichtig bei mehreren Filtern ist, dass diese bündig aneinander anschließen, damit keine Spalte bzw. Lücken zwischen den einzelnen Fettfiltern entstehen. Eine Anordnung mehrerer Filterkassetten aneinander, wobei ein Spalt zwischen den Filterkassetten vermieden wird, ist aus der Druckschrift WO 2005/075893 A1 und aus der Druckschrift EP 1 798 481 A2 bekannt.As a rule, the largest possible filter areas are preferred in order to provide the best possible filter effect. Then, depending on the structure of the housing, several adjacent grease filters often form a common filter surface. If there are several filters, it is important that they are flush with one another so that there are no gaps or gaps between the individual grease filters. An arrangement of several filter cassettes next to one another, with a gap between the filter cassettes being avoided, is from the document WO 2005/075893 A1 and from the pamphlet EP 1 798 481 A2 known.

Dann könnte nämlich fettbeladener Kochschwaden durch diese Spalte ins Innere der Dunstabzugshaube gelangen, diese verschmutzen und anschließend ungefiltert aus der Dunstabzugshaube wieder ausgeblasen werden.Then fat-laden steam could get through this gap into the interior of the extractor hood, contaminate it and then be blown out of the extractor hood again unfiltered.

Die Fettfilter sind von der Größe an einen bestimmten Aufnahmebereich der Dunstabzugshaube angepasst. Jedoch kann es durch Fertigungstoleranzen dazu kommen, dass die verwendeten Fettfilter zusammen nicht die gesamte Filterfläche abdecken. Dann können durch diese Toleranzen Freiräume bzw. Spalte zwischen den einzelnen Fettfiltern entstehen. Dies gilt es jedoch zu vermeiden. Um das Problem der Spaltbildung zu vermeiden, könnte man die Fertigung der verwendeten Teile präzisieren. Eine geringere Toleranz verursacht jedoch wesentlich höhere Fertigungskosten.The size of the grease filters is adapted to a certain area of the extractor hood. However, due to manufacturing tolerances, the grease filters used may not cover the entire filter surface. These tolerances can then result in free spaces or gaps between the individual grease filters. However, this should be avoided. In order to avoid the problem of gap formation, the manufacture of the parts used could be made more precise. However, a lower tolerance causes significantly higher manufacturing costs.

Zum Ausgleich der Toleranz ist aus der Druckschrift EP 2 060 853 A1 bekannt, dass einzelne Filterkassetten lösbar in einem Außenrahmen aufgenommen werden, welcher mit den Filterkassetten in einem Haushaltsgerät, insbesondere einer Dunstabzugshaube, eingesetzt wird.To compensate for the tolerance is from the publication EP 2 060 853 A1 known that individual filter cartridges are detachably received in an outer frame which is used with the filter cartridges in a household appliance, in particular an extractor hood.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Filtervorrichtung bereitzustellen, bei der auf einfache Art und Weise sichergestellt ist, dass eine geschlossene Filterfläche zur Verfügung gestellt wird, wobei die Toleranzen der einzelnen Filtereinrichtungen ausgeglichen werden.It is therefore the object of the present invention to provide a filter device in which it is ensured in a simple manner that a closed filter surface is made available, the tolerances of the individual filter devices being compensated.

Diese Aufgabe wird gelöst durch eine Filtervorrichtung mit den Merkmalen des Anspruchs 1. Bevorzugte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Weitere Vorteile und Merkmale der Erfindung ergeben sich aus den Ausführungsbeispielen.This object is achieved by a filter device having the features of claim 1. Preferred developments of the invention are the subject matter of the subclaims. Further advantages and features of the invention emerge from the exemplary embodiments.

Die erfindungsgemäße Filtervorrichtung umfasst wenigstens eine Gehäuseeinrichtung mit wenigstens einem Aufnahmeabschnitt für wenigstens zwei Filtereinrichtungen. Dabei ist an dem Aufnahmeabschnitt im eingesetzten Zustand der Filtereinrichtungen eine Filterfläche gebildet. Dem Aufnahmeabschnitt sind wenigstens eine Justiereinrichtung und/oder wenigstens eine Abdeckeinrichtung zugeordnet, die dazu geeignet und ausgebildet ist, die Filtereinrichtungen zu einer im Wesentlichen geschlossenen Filterfläche zusammenzuführen.The filter device according to the invention comprises at least one housing device with at least one receiving section for at least two filter devices. In this case, a filter surface is formed on the receiving section when the filter devices are in the inserted state. At least one adjusting device and / or at least one covering device are assigned to the receiving section, which adjustment device is suitable and designed to bring the filter devices together to form an essentially closed filter surface.

Erfindungsgemäß ist unter einer Filtereinrichtung insbesondere eine Dunstabzugshaube oder ein Teil davon zu verstehen. Eine Filtervorrichtung kann auch durch einen Lüfterbaustein zur Verfügung gestellt werden oder einen Teil des Lüfterbausteins darstellen.According to the invention, a filter device is to be understood as meaning in particular an extractor hood or a part thereof. A filter device can also be provided by a fan module or form part of the fan module.

Unter einer Filtereinrichtung ist erfindungsgemäß insbesondere ein Fettfilter zu verstehen, der vorzugsweise entnehmbar und wiedereinsetzbar an dem Aufnahmeabschnitt vorgesehen ist. Die Filterfläche wird insbesondere durch die Filtereinrichtungen gebildet. Dabei können zwei oder auch mehr Filtereinrichtungen nebeneinander oder auch anders benachbart angeordnet werden, sodass eine größere Filterfläche aus mehreren Filtereinrichtungen zusammengesetzt wird.According to the invention, a filter device is to be understood in particular as a grease filter which is preferably provided on the receiving section so that it can be removed and reinserted. The filter surface is formed in particular by the filter devices. Two or more filter devices can be arranged next to one another or also in a different manner adjacent so that a larger filter surface is composed of several filter devices.

Dass die Filterfläche im Wesentlichen geschlossen ist, heißt insbesondere, dass eine vollständig geschlossene Filterfläche zur Verfügung gestellt wird. Dabei ist erfindungsgemäß unter geschlossen insbesondere gemeint, dass die einzelnen Filtereinrichtungen derart nah aneinander liegen, dass es zu keiner Spaltbildung zwischen den einzelnen Filtereinrichtungen kommt. Dabei sind die einzelnen Filtereinrichtungen in dem Aufnahmeabschnitt insbesondere derart orientiert beziehungsweise durch die Justiereinrichtung positioniert, dass die Filtereinrichtungen vorzugsweise im Wesentlichen bündig aneinander angrenzen, sodass kein Spalt entsteht, durch welchen aufsteigender Wrasen ungefiltert hindurchtreten könnte. Erfindungsgemäß ist unter geschlossen insbesondere auch gemeint, dass es zu keiner Bildung eines strömungsdurchlässigen Spalts zwischen den einzelnen Filtereinrichtungen kommt. Dabei sind an den Rahmenabschnitten benachbarter Filtereinrichtungen und ggf. an den in dem Aufnahmeabschnitt angeordnetem Rahmenabschnitten der Filtereinrichtungen Abdeckeinrichtung angeordnet, wodurch ein eventuell zwischen den Filtereinrichtungen und zwischen Filtereinrichtung und Aufnahmeabschnitt vorhandene Differenz in der Längenausdehnung überdeckt ist, sodass ein strömungsdurchlässiger Spalt wesentlich verkürzt wird oder kein strömungsdurchlässiger Spalt entsteht, durch welchen aufsteigender Wrasen ungefiltert hindurchtreten könnte.The fact that the filter surface is essentially closed means in particular that a completely closed filter surface is made available. According to the invention, the term closed means in particular that the individual filter devices are so close to one another that there is no gap formation between the individual filter devices. The individual filter devices in the receiving section are in particular oriented or positioned by the adjusting device in such a way that the filter devices preferably adjoin one another essentially flush so that no Gap arises through which rising vapor could pass unfiltered. According to the invention, “closed” also means in particular that there is no formation of a flow-permeable gap between the individual filter devices. Covering devices are arranged on the frame sections of adjacent filter devices and possibly on the frame sections of the filter devices that are arranged in the receiving section, whereby any difference in length expansion that may exist between the filter devices and between the filter device and the receiving section is covered, so that a flow-permeable gap is substantially shortened or none A flow-permeable gap is created through which rising vapors could pass unfiltered.

Durch die Reduzierung der toleranzbedingten Spalte wird erreicht, dass die mit Ölen und Fetten verunreinigte Kochwrasen nicht mehr ungehindert - und somit nicht mehr ungefiltert - in die Dunstabzugshaube gelangen kann. Hierdurch wird der Fettabscheidegrad erhöht und die Verschmutzung im inneren der Dunstabzugshaube reduziert, wodurch der Reinigungsaufwand sinkt.By reducing the gap due to tolerances, it is achieved that the cooking vapors contaminated with oils and fats can no longer get into the extractor hood unhindered - and therefore no longer unfiltered. This increases the degree of grease separation and reduces soiling inside the extractor hood, which in turn reduces the cleaning effort.

An die Filterfläche schließt sich bevorzugt ein Absaugbereich an, der in der Regel wenigstens eine Gebläseeinrichtung umfasst. Durch ein solches Gebläse werden die von einer Kochstelle aufsteigenden Kochschwaden dann durch die Filtereinrichtungen ins Innere der Filtervorrichtung gesaugt. Dadurch wird der Wrasen insbesondere von Fettbestandteilen befreit.A suction area, which as a rule comprises at least one blower device, preferably adjoins the filter surface. By means of such a fan, the boiling steam rising up from a hotplate is then sucked through the filter devices into the interior of the filter device. This frees the vapor in particular from fat components.

Die erfindungsgemäße Filtervorrichtung bietet viele Vorteile. Ein erheblicher Vorteil ist, dass an dem Aufnahmeabschnitt eine aus mehreren Filtereinrichtungen bestehende Filterfläche gebildet wird, welche im Wesentlichen geschlossen ist. Durch das Vorsehen von mehreren Filtereinrichtungen kann auch bei einem schwer zugänglichen Aufnahmeabschnitt oder einem teilweise verbauten Aufnahmeabschnitt eine große Filterfläche gebildet werden. Dabei können die einzelnen Filtereinrichtungen durch die Justiereinrichtung bzw. auch durch mehrere Justiereinrichtungen derart zueinander positioniert werden, dass zwischen den einzelnen Filtereinrichtungen keine Spalte entstehen und/oder durch die Abdeckeinrichtung bzw. auch durch mehrere Abdeckeinrichtungen derart zueinander positioniert werden, dass zwischen den einzelnen Filtereinrichtungen keine Spalte entstehen.The filter device according to the invention offers many advantages. A considerable advantage is that a filter surface consisting of a plurality of filter devices is formed on the receiving section and is essentially closed. By providing several filter devices, a large filter surface can be formed even in the case of a receiving section that is difficult to access or a partially built-up receiving section. The individual filter devices can be positioned with respect to one another by the adjusting device or also by several adjusting devices in such a way that no gaps arise between the individual filter devices and / or by the covering device or also by several covering devices are positioned relative to one another in such a way that none between the individual filter devices Gaps arise.

So können Fertigungstoleranzen sowohl des Aufnahmebereichs als auch der einzelnen Filtereinrichtungen effektiv durch eine oder mehrere Justiereinrichtungen und/oder eine oder mehrere Abdeckeinrichtungen ausgeglichen werden. Dies kann die Fertigungskosten reduzieren bzw. gleichhalten, da die einzelnen Teile nicht mit einer geringeren Toleranz gefertigt werden müssen.Thus, manufacturing tolerances both of the receiving area and of the individual filter devices can be effectively compensated for by one or more adjustment devices and / or one or more cover devices. This can reduce the manufacturing costs or keep them the same, since the individual parts do not have to be manufactured with a lower tolerance.

Bevorzugt weist der Aufnahmeabschnitt eine Längsausdehnung auf und auch die Filtereinrichtungen weisen jeweils eine Längsausdehnung auf. Dabei ist sind die Abdeckeinrichtung und/oder die Justiereinrichtung dazu geeignet und ausgebildet, wenigstens eine Differenz zwischen der Summe der Längsausdehnungen der Filtereinrichtungen und der Längsausdehnung des Aufnahmeabschnitts auszugleichen. Zwar ist die Größe der einzelnen Filtereinrichtungen auf die Größe des Aufnahmeabschnitts angepasst. Dennoch kann es durch Fertigungstoleranzen dazu kommen, dass die Filtereinrichtungen zusammen eine geringere Längsausdehnung als die Längsausdehnung des Aufnahmeabschnitts aufweisen. Dann könnte es im ungünstigen Fall dazu kommen, dass die Filtereinrichtungen nicht bündig aneinander anliegen, wodurch zwischen wenigstens zwei Filtereinrichtungen ein Spalt entstehen kann.The receiving section preferably has a longitudinal extent and the filter devices also each have a longitudinal extent. The covering device and / or the adjusting device are suitable and designed to compensate for at least one difference between the sum of the longitudinal expansions of the filter devices and the longitudinal expanse of the receiving section. It is true that the size of the individual filter devices is adapted to the size of the receiving section. Nevertheless, due to manufacturing tolerances it can happen that the filter devices together have a smaller longitudinal extent than the longitudinal extent of the receiving section. In the worst case, it could then happen that the filter devices do not lie flush against one another, as a result of which a gap can arise between at least two filter devices.

Durch die Justiereinrichtung wird erreicht, dass zum Beispiel durch Fertigungstoleranzen auftretende Differenzen in der Längsausdehnung derart ausgeglichen werden, dass kein Spalt zwischen den Filtereinrichtungen entsteht, sodass eine geschlossene Filterfläche zur Verfügung gestellt wird. Durch die Abdeckeinrichtung wird erreicht, dass zum Beispiel durch Fertigungstoleranzen auftretende Differenzen in der Längsausdehnung derart ausgeglichen werden, dass ein möglicher Spalt zwischen den Filtereinrichtungen überdeckt wird, sodass eine geschlossene Filterfläche zur Verfügung gestellt wird.The adjustment device ensures that, for example, differences in the longitudinal extent that occur due to manufacturing tolerances are compensated for in such a way that no gap arises between the filter devices, so that a closed filter surface is made available. The cover device ensures that, for example, differences in the longitudinal extent that occur due to manufacturing tolerances are compensated for in such a way that a possible gap between the filter devices is covered so that a closed filter surface is made available.

Besonders bevorzugt ist die Justiereinrichtung der Gehäuseeinrichtung zugeordnet. In einer solchen vorteilhaften Ausgestaltung ist die Justiereinrichtung an der Gehäuseeinrichtung und insbesondere an dem Aufnahmeabschnitt der Gehäuseeinrichtung vorgesehen. Hierdurch wird es unter anderem möglich, dass alle Filtereinrichtungen gleich ausgestaltet werden können, da die Justiereinrichtung an der Gehäuseeinrichtung und nicht an einer oder mehreren Filtereinrichtungen vorgesehen ist.The adjusting device is particularly preferably assigned to the housing device. In such an advantageous embodiment, the adjusting device is provided on the housing device and in particular on the receiving section of the housing device. This makes it possible, among other things, for all filter devices to be configured identically, since the adjustment device is provided on the housing device and not on one or more filter devices.

In vorteilhaften Weiterbildungen weist der Aufnahmeabschnitt wenigstens eine obere Anlagefläche und wenigstens eine seitliche Anlagefläche zur Abstützung der Filtereinrichtungen auf. Durch diese beiden Anlageflächen wird eine Art Kragen an der Gehäuseeinrichtung beziehungsweise an dem Aufnahmeabschnitt zur Verfügung gestellt, in welchen die Filtereinrichtungen eingesetzt werden können. Dabei stützen sich die Filtereinrichtungen in zweckmäßigen Ausgestaltungen gegen die Anlageflächen ab, wobei eine Fixierung der Filtereinrichtungen über bekannte Befestigungsmechanismen erreicht werden kann. Dabei können die Filtereinrichtungen z. B. an einer Seite eingehakt werden und dann anschließend an der anderen Seite mittels eines Schnappverschlusses oder einer anderen Verrastung an dem Aufnahmeabschnitt fixiert werden.In advantageous developments, the receiving section has at least one upper contact surface and at least one lateral contact surface for supporting the filter devices. These two contact surfaces provide a type of collar on the housing device or on the receiving section, in which the filter devices can be inserted. In this case, the filter devices are supported in expedient configurations against the contact surfaces, it being possible to fix the filter devices using known fastening mechanisms. The filter devices can, for. B. be hooked on one side and then subsequently fixed on the other side by means of a snap lock or other latching on the receiving section.

Vorzugsweise sind die obere und die untere Anlagefläche wenigstens abschnittsweise den Aufnahmeabschnitt umlaufend ausgebildet. Hierdurch wird eine besonders gute Anlage der einzelnen Filtereinrichtungen an dem Aufnahmeabschnitt ermöglicht.Preferably, the upper and the lower contact surface are designed at least in sections to run around the receiving section. This enables the individual filter devices to rest particularly well on the receiving section.

Bevorzugt ist die Justiereinrichtung wenigstens einer seitlichen Anlagefläche zugeordnet. Dabei kann die Justiereinrichtung insbesondere der linken und/oder der rechten seitlichen Anlagefläche zugeordnet sein. Vorzugsweise ist die Justiereinrichtung insbesondere einer solchen seitlichen Anlagefläche zugeordnet, dass eine an der Justiereinrichtung anliegende Filtereinrichtung mittels der Justiereinrichtung in Richtung einer benachbarten Filtereinrichtung verlagerbar ist.The adjusting device is preferably assigned to at least one lateral contact surface. The adjusting device can in particular be assigned to the left and / or the right lateral contact surface. The adjustment device is preferably assigned in particular to such a lateral contact surface that a filter device resting on the adjustment device can be displaced by means of the adjustment device in the direction of an adjacent filter device.

Besonders bevorzugt sind wenigstens zwei Justiereinrichtungen vorgesehen, wobei die Justiereinrichtungen an sich gegenüberliegenden seitlichen Anlageflächen vorgesehen sind. Dabei sind die beiden Justiereinrichtungen insbesondere an der linken und der rechten seitlichen Anlagefläche vorgesehen. Durch das Vorsehen von Justiereinrichtungen an wenigstens zwei Seiten des Aufnahmeabschnitts wird erreicht, dass die einzelnen Filtereinrichtungen symmetrisch verteilt im Aufnahmeabschnitt angeordnet werden.At least two adjustment devices are particularly preferably provided, the adjustment devices being provided on opposite lateral contact surfaces. The two adjusting devices are provided in particular on the left and right lateral contact surfaces. By providing adjustment devices on at least two sides of the receiving section, it is achieved that the individual filter devices are arranged symmetrically distributed in the receiving section.

Erfindungsgemäß umfasst die Justiereinrichtung wenigstens eine Federeinrichtung. Durch eine solche Federeinrichtung kann eine eventuell entstehende Differenz zwischen der Längsausdehnung des Aufnahmeabschnitts und der Summe der Längsausdehnungen der Filtereinrichtungen effektiv ausgeglichen werden. Ein sonst eventuell entstehender Spalt kann dann dadurch vermieden werden, dass die Federeinrichtung wenigstens eine Filtereinrichtung in Richtung der benachbarten Filtereinrichtung drückt, wodurch die beiden Filtereinrichtungen bündig aneinander anliegen. So entsteht eine im Wesentlichen vollständig geschlossene Filterfläche.According to the invention, the adjusting device comprises at least one spring device. By means of such a spring device, any difference that may arise between the longitudinal extension of the receiving section and the sum of the longitudinal extensions of the filter devices can be effectively compensated for. A gap that might otherwise arise can then be avoided in that the spring device presses at least one filter device in the direction of the adjacent filter device, as a result of which the two filter devices lie flush against one another. This creates an essentially completely closed filter surface.

Erfindungsgemäß ist die Federeinrichtung einteilig mit der Gehäuseeinrichtung gefertigt. Dabei ist die Justiereinrichtung beziehungsweise die Federeinrichtung insbesondere einteilig mit dem Aufnahmeabschnitt gefertigt. So kann eine Federeinrichtung auf eine einfache Art zur Verfügung gestellt werden, ohne dass separate Teile an der Gehäuseeinrichtung befestigt werden müssen.According to the invention, the spring device is manufactured in one piece with the housing device. The adjusting device or the spring device is in particular manufactured in one piece with the receiving section. A spring device can thus be provided in a simple manner without separate parts having to be attached to the housing device.

Erfindungsgemäß wird die Federeinrichtung durch wenigstens eine Perforation in der Gehäuseeinrichtung zur Verfügung gestellt. So wird erreicht, dass sich der durch die Perforation begrenzte Bereich der Gehäuseeinrichtung insbesondere nach außen weg verformen kann. Erfindungsgemäß umfasst die Justiereinrichtung wenigstens eine Distanzeinrichtung. Eine solche Distanzeinrichtung dient insbesondere zum Ausgleich eines eventuell durch Fertigungstoleranzen entstehenden Spaltes zwischen wenigstens zwei Filtereinrichtungen.According to the invention, the spring device is made available by at least one perforation in the housing device. What is achieved in this way is that the area of the housing device delimited by the perforation can deform away in particular towards the outside. According to the invention, the adjusting device comprises at least one distance device. Such a spacer device is used in particular to compensate for a gap that may possibly arise between at least two filter devices due to manufacturing tolerances.

Dabei umfasst die Distanzeinrichtung besonders bevorzugt wenigstens ein Kunststoffteil. Durch ein solches Kunststoffteil kann eine bestimmte Distanz gut überbrückt werden, wobei durch die Ausgestaltung aus Kunststoff eine besonders schonende Anlage der Filtereinrichtung an der Justiereinrichtung ermöglicht wird.The spacer device particularly preferably comprises at least one plastic part. By means of such a plastic part, a certain distance can be bridged well, with the design made of plastic allowing the filter device to rest particularly gently on the adjusting device.

Erfindungsgemäß umfasst die Distanzeinrichtung wenigstens einen Befestigungsabschnitt und wenigstens einen Distanzabschnitt. Die Distanzeinrichtung kann dann vorzugsweise mittels des Befestigungsabschnitts an der Federeinrichtung aufgenommen werden. Bevorzugt gleicht der Distanzabschnitt Toleranzen aus, die zu einem Spalt zwischen zwei Filtereinrichtungen führen würden.According to the invention, the spacer device comprises at least one fastening section and at least one spacer section. The spacer device can then preferably be received on the spring device by means of the fastening section. The spacer section preferably compensates for tolerances which would lead to a gap between two filter devices.

Dazu weist der Distanzabschnitt eine Stärke auf, die an die größte anzunehmende Differenz der Längsausdehnungen angepasst ist. Dabei ist dies insbesondere der Fall, wenn nur an einer Seite des Aufnahmeabschnitts eine Justiereinrichtung vorgesehen ist. Sind an beiden Seiten des Aufnahmeabschnitts Justiereinrichtungen vorgesehen, beträgt die Stärke der Distanzabschnitte bevorzugt entsprechend jeweils der Hälfte der größten anzunehmenden Differenz zwischen den Längsausdehnungen.For this purpose, the spacer section has a thickness which is adapted to the greatest difference to be assumed between the longitudinal dimensions. This is particularly the case when an adjusting device is provided on only one side of the receiving section. If adjusting devices are provided on both sides of the receiving section, the thickness of the spacer sections is preferably in each case corresponding to half of the greatest difference to be assumed between the longitudinal dimensions.

Erfindungsgemäß ist die Distanzeinrichtung an der Federeinrichtung aufgenommen. Dazu weist die Federeinrichtung insbesondere eine Aufnahme für die Distanzeinrichtung auf. Eine solche Aufnahme kann in einer einfachen Ausgestaltung durch eine Durchgangsöffnung zur Verfügung gestellt werden, in welche bevorzugt der Befestigungsabschnitt der Distanzeinrichtung aufgenommen werden kann.According to the invention, the spacer device is received on the spring device. For this purpose, the spring device has in particular a receptacle for the spacer device. In a simple embodiment, such a receptacle can be provided by a through opening into which the fastening section of the spacer device can preferably be received.

Es hat sich als günstig erwiesen, dass die wenigstens eine Abdeckeinrichtung zumindest ein Abdeckelement umfasst, welches lösbar an der Gehäuseeinrichtung und/oder an wenigstens einem Rahmenabschnitt einer der Filtereinrichtungen angeordnet ist. Hierdurch ist es für den Nutzer auf einfache Weise möglich die Filtereinrichtungen einzeln der Gehäusevorrichtung zu entnehmen und alle Teile, insbesondere die Filtereinrichtungen und die Abdeckeinrichtungen, leicht zu reinigen, beispielsweise in einem Geschirrspülautomaten.It has proven to be favorable that the at least one cover device comprises at least one cover element which is detachably arranged on the housing device and / or on at least one frame section of one of the filter devices. This makes it easy for the user to remove the filter devices individually from the housing device and to easily clean all parts, in particular the filter devices and the cover devices, for example in an automatic dishwasher.

Es ist vorgesehen, dass die wenigstens eine Abdeckeinrichtung zumindest eine Halteeinrichtung für das Abdeckelement aufweist, wobei die Halteeinrichtung an der Gehäuseeinrichtung befestigt ist und das Abdeckelement lösbar mit der Halteeinrichtung verbunden ist. Weiterhin ist vorgesehen, dass die wenigstens eine Abdeckeinrichtung wenigstens eine Verbindungseinrichtung umfasst, wobei das Abdeckelement mittels der Verbindungseinrichtung lösbar an der zumindest einen Halteeinrichtung und/oder an dem wenigstens einem Rahmenabschnitt gehalten ist.It is provided that the at least one cover device has at least one holding device for the cover element, the holding device being fastened to the housing device and the cover element being detachably connected to the holding device. It is further provided that the at least one cover device comprises at least one connecting device, the cover element being releasably held by means of the connecting device on the at least one holding device and / or on the at least one frame section.

Das Abdeckelement weist eine Breite aufweist, die wenigstens einer größten anzunehmenden Differenz der Längsausdehnungen entspricht, vorzugsweise der Rahmenbreite eines Rahmenabschnittes, in besonders bevorzugter Weise der doppelten Rahmenbreite eines Rahmenabschnittes entspricht. Hierdurch werden eine ausreichende Überdeckung und ein sicherer Verschluss eines gegebenenfalls sich zwischen zwei Filtereinrichtungen ergebenen Spalts gewährleistet.The cover element has a width that corresponds to at least one of the greatest differences to be assumed between the longitudinal dimensions, preferably the frame width of a frame section, in a particularly preferred manner corresponds to twice the frame width of a frame section. This ensures adequate coverage and secure closure of any gap that may arise between two filter devices.

Bevorzugt weist die wenigstens eine Verbindungseinrichtung zwei einander gegenüberliegende Verbindungspartner auf, wobei ein erster der Verbindungspartner an einem Rahmenabschnitt und/oder an einem Abdeckelement angeordnet ist. Ein weiterer der Verbindungspartner ist an einem Rahmenabschnitt und/oder an einer Halteeinrichtung angeordnet.The at least one connection device preferably has two mutually opposite connection partners, a first of the connection partners being arranged on a frame section and / or on a cover element. Another of the connection partners is arranged on a frame section and / or on a holding device.

Als besonders günstig erwiesen hat es sich, dass mindestens der eine der Verbindungspartner ein Dauermagnet ist und der zugehörige andere der Verbindungspartner entweder ein von diesem Dauermagneten magnetisch anziehbares Material oder ein von diesem Dauermagneten magnetisch anziehbarer weiterer Dauermagnet mit entgegengesetzter Polarität ist.It has proven particularly advantageous that at least one of the connection partners is a permanent magnet and the associated other connection partner is either a material that can be magnetically attracted by this permanent magnet or a further permanent magnet with opposite polarity that can be magnetically attracted by this permanent magnet.

Ebenso günstig ist es, dass mindestens der eine der Verbindungspartner eine Nut mit einem Rastvorsprung ist und der zugehörige andere der Verbindungspartner ein in dieser Nut anordenbare Feder mit einem Rastvorsprung ist. Bevorzugt ist die Feder ein längsgestrecktes, insbesondere mit dem Abdeckelement einteilig ausgeführtes, Profil. Die Feder kann jedoch auch als Stift ausgeführt sein. Zum verbesserten Halt der Verbindung ist es günstig, dass die Nut und/oder der wenigstens eine Rastvorsprung der Nut und/oder der wenigstens eine Rastvorsprung der Feder elastisch verformbar ist.It is also favorable that at least one of the connection partners is a groove with a latching projection and the associated other of the connection partners is a tongue with a latching projection that can be arranged in this groove. The spring is preferably an elongated profile, in particular one that is embodied in one piece with the cover element. However, the spring can also be designed as a pin. For an improved hold of the connection, it is favorable that the groove and / or the at least one latching projection of the groove and / or the at least one latching projection of the tongue can be elastically deformed.

Die Ausführung der Verbindungseinrichtung mittels einer magnetischen oder rastmechanischen Kopplung erlaubt es dem Nutzer werkzeuglos eine Verbindung herzustellen und aufzulösen. Dies erleichtert die Handhabung der Komponenten und damit den Umgang mit der gesamten Filtervorrichtung.The implementation of the connection device by means of a magnetic or snap-in mechanical coupling allows the user to establish and disconnect a connection without tools. This facilitates the handling of the components and thus the handling of the entire filter device.

Vorzugsweise sind an mehreren Stellen der Rahmenabschnitte der Filtereinrichtungen und optional auch an mehreren Stellen des Aufnahmeabschnittes Verbindungseinrichtungen vorgesehen. Dabei sind insbesondere bei zwei benachbart angeordneten Filtereinrichtungen die Verbindungspartner paarweise einander gegenüberliegend angeordnet. Durch die beispielsweise Verwendung eines Dauermagneten bei wenigstens einem der paarweise vorgesehenen Verbindungspartner ist es möglich, dass sich die Filtereinrichtungen einander Anziehen und so der Spalt zwischen den Filtereinrichtungen reduziert wird. Bei den Verbindungspartnern an den Verbindungsstellen von Filtereinrichtung und Aufnahmeabschnitt hat es sich hingegen als günstig erwiesen, dass beide Verbindungspartner als Dauermagneten ausgeführt sind, wobei diese hinsichtlich ihrer Polung derart ausgerichtet sind, dass sich die Filtereinrichtung von dem Aufnahmeabschnitt abstößt. Alternativ können einzelne oder alle Verbindungseinrichtungen zwischen zwei benachbarten Filtereinrichtungen auch Nut und Feder ausgeführt sein. Weitere Vorteile und Merkmale der vorliegenden Erfindung ergeben sich aus den Ausführungsbeispielen, welche im Folgenden mit Bezug auf die beiliegenden Figuren erläutert werden.Connection devices are preferably provided at several locations on the frame sections of the filter devices and optionally also at several locations on the receiving section. In this case, particularly in the case of two adjacent filter devices, the connection partners are arranged opposite one another in pairs. For example, by using a permanent magnet in at least one of the pairs provided connection partner, it is possible that the filter devices attract each other and thus the gap between the filter devices is reduced. In the case of the connection partners at the connection points between the filter device and the receiving section, however, it has proven to be beneficial that both connection partners are designed as permanent magnets, with their polarity being aligned in such a way that the filter device repels itself from the receiving section. Alternatively, individual or all connecting devices between two adjacent filter devices can also be tongue and groove. Further advantages and features of the present invention emerge from the exemplary embodiments, which are explained below with reference to the accompanying figures.

In Figur 1 sieht man eine erfindungsgemäße Filtereinrichtung 1 in einer rein schematischen perspektivischen Ansicht von unten. Die Filtervorrichtung 1 ist hinsichtlich ihres Einsatzes nicht auf eine spezielle Dunstabzugshaube 101 beschränkt sondern kann in Wandhauben 100, aber auch in Inselhauben und anderen Ausführungsformen eingesetzt werden. Man schaut auf die Unterseite 24 der Filtervorrichtung 1, wobei die im vorderen Bereich zu sehenden Lampen 25 im installierten Zustand der Filtervorrichtung 1 nach unten auf eine in Figur 1 nicht dargestellte Kochstelle strahlen.In Figure 1 one sees a filter device 1 according to the invention in a purely schematic perspective view from below. With regard to its use, the filter device 1 is not limited to a special extractor hood 101 but can be used in wall-mounted hoods 100, but also in island hoods and other embodiments. One looks at the underside 24 of the filter device 1, the lamps 25 to be seen in the front area in the installed state of the filter device 1 pointing downwards to an in Figure 1 Not shown hotplate shine.

Die Filtervorrichtung 1 umfasst eine Gehäuseeinrichtung 2, welche einen Aufnahmeabschnitt 3 zur Verfügung stellt, an welchem eine Filterfläche 6 ausgebildet werden kann. Die Filterfläche 6 wird in dem hier gezeigten Ausführungsbeispiel durch drei Filtereinrichtungen 4, 5, 21 gebildet, welche nebeneinander in dem Aufnahmeabschnitt 3 angeordnet sind. In anderen Ausführungsformen können auch nur zwei oder mehr als drei Filtereinrichtungen vorgesehen sein. Die Filtereinrichtungen können auch in mehreren Reihen vorgesehen werden.The filter device 1 comprises a housing device 2 which provides a receiving section 3 on which a filter surface 6 can be formed. In the exemplary embodiment shown here, the filter surface 6 is formed by three filter devices 4, 5, 21 which are arranged next to one another in the receiving section 3. In other embodiments, only two or more than three filter devices can also be provided. The filter devices can also be provided in several rows.

An den Aufnahmeabschnitt 3 bzw. an die Filterfläche 6 schließt sich in dem hier gezeigten Ausführungsbeispiel ein Ansaugbereich 35 mit einer Gebläseeinrichtung an, welche aufsteigende Kochschwaden durch die Filtereinrichtungen 4, 5, 21 ins Innere der Filtervorrichtung 1 saugt. Der Ansaugbereich 35 ist in der Figur 6 dargestellt. Die Gebläseeinrichtung ist in den Figuren nicht näher dargestellt. Die Gebläseeinrichtung kann auch als externes Gebläse außerhalb der Dunstabzugshaube ausgebildet sein.In the exemplary embodiment shown here, a suction area 35 with a fan device adjoins the receiving section 3 or the filter surface 6, which Sucks rising boiling steam through the filter devices 4, 5, 21 into the interior of the filter device 1. The suction area 35 is in the Figure 6 shown. The fan device is not shown in detail in the figures. The fan device can also be designed as an external fan outside of the extractor hood.

Die Filtereinrichtungen 4 sind als Fettfilter 26 ausgebildet, welche jeweils einen Rahmenabschnitt 27 und einen Filterabschnitt 28 aufweisen. Die Fettfilter 26 werden in der hier gezeigten Ausführungsform an einer Seite 31 in den Aufnahmeabschnitt 3 eingehakt. Auf der anderen Seite 32 ist ein Befestigungselement 29 vorgesehen, welches hier als Schnappverschluss 30 ausgebildet ist.The filter devices 4 are designed as grease filters 26 which each have a frame section 27 and a filter section 28. In the embodiment shown here, the grease filters 26 are hooked into the receiving section 3 on one side 31. On the other side 32, a fastening element 29 is provided, which is designed here as a snap lock 30.

Der Aufnahmeabschnitt 3 weist eine Längsausdehnung 8 auf, welche in dem hier gezeigten Ausführungsbeispiel ungefähr der dreifachen Längsausdehnung der drei Filtereinrichtungen 4, 5, 21 entspricht.The receiving section 3 has a longitudinal extent 8 which, in the exemplary embodiment shown here, corresponds approximately to three times the longitudinal extent of the three filter devices 4, 5, 21.

Dabei ist es vorteilhaft, wenn sich die einzelnen Längsausdehnungen 9, 10, 22 der einzelnen Filtereinrichtungen 4, 5, 21 zu der Längsausdehnung 8 des Aufnahmeabschnitts 3 addieren. So kann sichergestellt werden, dass die einzelnen Filtereinrichtungen 4, 5, 21 im Wesentlichen bündig aneinander anliegen, sodass eine im Wesentlichen vollständig geschlossene Filterfläche 6 zur Verfügung gestellt wird. Insbesondere muss sichergestellt werden, dass zwischen den Filtereinrichtungen 4, 5, 21 kein Spalt entstehen kann, wodurch aufsteigender Kochschwaden ungefiltert in die Gehäuseeinrichtung 2 gelangen könnte.It is advantageous if the individual longitudinal extensions 9, 10, 22 of the individual filter devices 4, 5, 21 add up to the longitudinal extension 8 of the receiving section 3. It can thus be ensured that the individual filter devices 4, 5, 21 lie essentially flush against one another, so that an essentially completely closed filter surface 6 is made available. In particular, it must be ensured that no gap can arise between the filter devices 4, 5, 21, as a result of which rising boiling steam could reach the housing device 2 unfiltered.

Bedingt durch Fertigungstoleranzen ist es jedoch möglich, dass eine Differenz 11 zwischen der Längsausdehnung 8 des Aufnahmeabschnitts 3 und der Summe der Längsausdehnungen 9, 10, 22 der Filtereinrichtungen 4, 5, 21 entsteht. Dann könnte es je nach Anordnung der Filtereinrichtungen 4, 5, 21 zu einer Spaltbildung zwischen wenigstens zwei Filtereinrichtungen 4, 5, 21 kommen.Due to manufacturing tolerances, however, it is possible that a difference 11 arises between the longitudinal extent 8 of the receiving section 3 and the sum of the longitudinal extents 9, 10, 22 of the filter devices 4, 5, 21. Then, depending on the arrangement of the filter devices 4, 5, 21, a gap could form between at least two filter devices 4, 5, 21.

Um dies zu vermeiden, ist es vorteilhaft, wenn die Filtereinrichtungen 4, 5, 21 in Richtung der Längsausrichtung 8 des Aufnahmeabschnitts bündig in Richtung Mitte des Aufnahmeabschnitts 3 zusammengeschoben werden. So kann sichergestellt werden, dass die Filtereinrichtungen 4, 5, 21 bündig aneinander anliegen, sodass es nicht zu einer unerwünschten Spaltbildung kommt. Im Außenbereich des Aufnahmeabschnitts können konstruktionsbedingt gewisse Spaltmaße zwischen einer Filtereinrichtung 4, 5, 21 und der Gehäuseeinrichtung 2 ausgeglichen werden. Dies resultiert unter anderem aus den im Aufnahmeabschnitt 3 im Wesentlichen umlaufenden Anlageflächen 12, 13, welche näher in den Figuren 2 und 3 dargestellt sind.To avoid this, it is advantageous if the filter devices 4, 5, 21 are pushed together flush in the direction of the longitudinal alignment 8 of the receiving section 3 in the direction of the center of the receiving section 3. It can thus be ensured that the filter devices 4, 5, 21 lie flush against one another, so that there is no undesirable gap formation. In the outer area of the receiving section, certain gap dimensions between a filter device 4, 5, 21 and the housing device 2 can be compensated for due to the design. This results, among other things, from the contact surfaces 12, 13 which are essentially circumferential in the receiving section 3 and which are shown in more detail in FIGS Figures 2 and 3 are shown.

Damit die Filtereinrichtungen 4, 5, 21 bündig in Richtung der Mitte des Aufnahmeabschnitts 3 zusammengeschoben werden, sind in dem hier gezeigten Ausführungsbeispiel 4 Justiereinrichtungen 7 vorgesehen. Dabei sind die Justiereinrichtungen 7 an der linken Seite 33 und der rechten Seite 34 der Gehäuseeinrichtung 2 vorgesehen. In anderen Ausgestaltungen kann an jeder Seite auch nur eine Justiereinrichtung vorteilhaft vorgesehen werden. Wenn keine symmetrische Ausrichtung der Filtereinrichtungen 4, 5, 21 innerhalb des Aufnahmeabschnitts 3 erforderlich ist, kann auch nur eine Seite 33 oder 34 mit Justiereinrichtungen 7 oder sogar nur mit einer einzigen Justiereinrichtung 7 ausgestattet sein.So that the filter devices 4, 5, 21 are pushed together flush in the direction of the center of the receiving section 3, 4 adjusting devices 7 are provided in the exemplary embodiment shown here. The adjusting devices 7 are provided on the left side 33 and the right side 34 of the housing device 2. In other configurations, only one adjusting device can advantageously be provided on each side. If a symmetrical alignment of the filter devices 4, 5, 21 within the receiving section 3 is not required, only one side 33 or 34 can also be equipped with adjustment devices 7 or even only with a single adjustment device 7.

In Figur 2 ist rein schematisch eine Ansicht auf dem Aufnahmeabschnitt 3 einer Gehäuseeinrichtung 2 einer erfindungsgemäßen Filtervorrichtung 1 in einer perspektivischen Ansicht dargestellt. Dabei ist zur besseren Übersicht nur die Gehäuseeinrichtung 2 ohne die Filtereinrichtungen 4, 5, 21 dargestellt. Weiterhin ist eine Justiereinrichtung 7 in einer Vergrößerung dargestellt.In Figure 2 is a purely schematic view of the receiving section 3 of a housing device 2 of a filter device 1 according to the invention in a perspective view. For a better overview, only the housing device 2 is shown without the filter devices 4, 5, 21. Furthermore, an adjusting device 7 is shown enlarged.

Die Gehäuseeinrichtung 2 weist an dem Aufnahmeabschnitt 3 seitliche Anlageflächen 13 und obere Anlageflächen 12 auf, welche die eingelegten Filtereinrichtungen 4, 5, 21 abstützen. Die obere Anlagefläche 12 ist in Figur 2 nach unten gerichtet, da auch in Figur 2 wie schon in Figur 1 eine Ansicht auf die untere Seite der Filtervorrichtung 1 gezeigt ist.The housing device 2 has lateral contact surfaces 13 and upper contact surfaces 12 on the receiving section 3, which support the inserted filter devices 4, 5, 21. The upper contact surface 12 is in Figure 2 directed downwards, since also in Figure 2 as in Figure 1 a view of the lower side of the filter device 1 is shown.

Durch die entnommenen Filtereinrichtungen 4, 5, 21 wird insbesondere der Blick auf die Anlagefläche 12 auf der linken Seite 33 des Aufnahmeabschnitts 3 frei, an welcher Justiereinrichtungen 7 vorgesehen sind. Die Justiereinrichtungen 7 umfassen jeweils eine Federeinrichtung 14, die in der hier gezeigten Ausführungsform durch eine Perforation 15 in der Gehäuseeinrichtung 2 zur Verfügung gestellt wird. Somit ist die Federeinrichtung 14 einteilig mit der Gehäuseeinrichtung 2 gefertigt. In anderen Ausführungsformen kann die Justiereinrichtung 7 oder die Federeinrichtung 14 auch als separates Teil vorgesehen sein. Die Federeinrichtung 14 weist eine Aufnahme 23 für eine Distanzeinrichtung 16 auf.The removed filter devices 4, 5, 21 in particular open up a view of the contact surface 12 on the left side 33 of the receiving section 3, on which adjustment devices 7 are provided. The adjusting devices 7 each include a spring device 14 which, in the embodiment shown here, is made available through a perforation 15 in the housing device 2. The spring device 14 is thus manufactured in one piece with the housing device 2. In other embodiments, the adjusting device 7 or the spring device 14 can also be provided as a separate part. The spring device 14 has a receptacle 23 for a spacer device 16.

In Figur 3 ist die Ansicht gemäß Figur 2 erneut dargestellt, wobei in die Federeinrichtung 14 der Justiereinrichtung 7 eine Distanzeinrichtung 16 eingesteckt ist. Die Distanzeinrichtung 16 wird hier durch ein Kunststoffteil 17 zur Verfügung gestellt, welches einen Befestigungsabschnitt 18 und einen Distanzabschnitt 19 aufweist. Die Distanzeinrichtung 16 ist im Detail in Figur 5 dargestellt.In Figure 3 is the view according to Figure 2 shown again, a spacer device 16 being inserted into the spring device 14 of the adjusting device 7. The spacer device 16 is provided here by a plastic part 17 which has a fastening section 18 and a spacer section 19. The spacer device 16 is shown in detail in Figure 5 shown.

Dabei ist der Befestigungsabschnitt 18 der Distanzeinrichtung 16 in eine Aufnahme 23 in der Federeinrichtung 14 eingesteckt. Das Distanzelement 16 dient zum Ausgleich einer Differenz 11 zwischen der Summe der Längsausdehnungen 9, 10, 22 der Filtereinrichtungen 4, 5, 21 und der Längsausdehnung 8 des Aufnahmeabschnitts 3.The fastening section 18 of the spacer device 16 is inserted into a receptacle 23 in the spring device 14. The spacer element 16 serves to compensate for a difference 11 between the sum of the longitudinal extensions 9, 10, 22 of the filter devices 4, 5, 21 and the longitudinal extension 8 of the receiving section 3.

Dazu weist der Distanzabschnitt 19 eine Stärke 20 auf, die je nach Ausführungsform an eine größte anzunehmende Differenz 11 angepasst ist. Sind die Filtereinrichtungen 4, 5, 21 oder auch nur eine davon durch Fertigungstoleranzen zu schmal ausgeführt, würde es in der Filterfläche 6 zu einer Spaltbildung kommen. Um dies zu verhindern, werden die äußeren Filtereinrichtungen 4, 21 durch die Justiereinrichtungen 7 derart in die Mitte des Aufnahmeabschnitts 2 geschoben, dass die Filtereinrichtungen 4, 5, 21 bündig aneinander anliegen und so eine geschlossene Filterfläche 6 bilden.For this purpose, the spacer section 19 has a thickness 20 which, depending on the embodiment, is adapted to a greatest difference 11 to be assumed. If the filter devices 4, 5, 21 or even just one of them are too narrow due to manufacturing tolerances, a gap would form in the filter surface 6. In order to prevent this, the outer filter devices 4, 21 are pushed by the adjusting devices 7 into the center of the receiving section 2 in such a way that the filter devices 4, 5, 21 lie flush against one another and thus form a closed filter surface 6.

Je nach Längsausdehnung 9, 10, 22 der Filtereinrichtungen 4, 5, 21 kann die Stärke 20 des Distanzabschnitts 19 der Distanzeinrichtung 16 die Längsausdehnung 8 des Aufnahmeabschnitts 3 zu sehr beschränken. Dann federt das Distanzelement 16 zusammen mit der Federeinrichtung 14 nach außen weg, sodass immer ein optimaler Abstand zwischen der Gehäuseeinrichtung 2 und den äußeren Filtereinrichtungen 4, 21 besteht. So wird eine Spaltbildung effektiv vermieden.Depending on the longitudinal extent 9, 10, 22 of the filter devices 4, 5, 21, the thickness 20 of the spacer section 19 of the spacer device 16 can restrict the longitudinal extent 8 of the receiving section 3 too much. Then the spacer element 16 springs away together with the spring device 14, so that there is always an optimal distance between the housing device 2 and the outer filter devices 4, 21. This effectively prevents the formation of a gap.

Damit die Distanzeinrichtung 16 zusammen mit der Federeinrichtung 14 nach außen wegfedern kann, ist die Form der Distanzeinrichtung 16 und insbesondere die Form des Distanzabschnitts 19 an die Formgebung der Federeinrichtung 14 angepasst, sodass die Distanzeinrichtung 16 durch die seitliche Anlagefläche 13 nach außen durchtauchen kann, sodass ausreichend Platz für die Filtereinrichtungen 4, 5, 21 im Aufnahmeabschnitt 3 zur Verfügung steht.So that the spacer device 16 can spring away outwards together with the spring device 14, the shape of the spacer device 16 and in particular the shape of the spacer section 19 is adapted to the shape of the spring device 14 so that the spacer device 16 can penetrate outward through the lateral contact surface 13 so that there is sufficient space for the filter devices 4, 5, 21 in the receiving section 3.

In Figur 4 sind rein schematisch zwei Einbausituationen von Filtereinrichtungen 4, 5, 21 dargestellt, wobei nur die Filtereinrichtung 4 abschnittsweise dargestellt ist.In Figure 4 Two installation situations of filter devices 4, 5, 21 are shown purely schematically, only the filter device 4 being shown in sections.

In der linken dargestellten Einbausituation ist eine maximale Differenz 11 zwischen den Längsausdehnungen 9, 10, 22 der Filtereinrichtungen 4, 5, 21 und der Längsausdehnung 8 des Aufnahmeabschnitts 3 gegeben. Dann liegt die Federeinrichtung 14 bündig in der seitlichen Anlagefläche 13 und die Distanzeinrichtung 16 beziehungsweise der Distanzabschnitt 19 steht vollständig in den Aufnahmeabschnitt 3 hinein. In dieser Position wird die Filtereinrichtung 4 durch den Distanzabschnitt 19 in Richtung der Mitte des Aufnahmeabschnitts 3 geschoben, sodass die Filtereinrichtungen 4, 5, 21 bündig aneinander anliegen.In the installation situation shown on the left, there is a maximum difference 11 between the longitudinal extensions 9, 10, 22 of the filter devices 4, 5, 21 and the longitudinal extension 8 of the receiving section 3. Then the spring device 14 lies flush in the lateral contact surface 13 and the spacer device 16 or the spacer section 19 protrudes completely into the receiving section 3. In this position, the filter device 4 is pushed through the spacer section 19 in the direction of the center of the receiving section 3, so that the filter devices 4, 5, 21 lie flush against one another.

In der rechts in Figur 4 dargestellten Einbausituation sind die Filtereinrichtungen 4, 5, 21 etwas breiter gefertigt, so dass nur ein kleiner Spalt entstehen würde. Dann federt die Federeinrichtung 14 durch die seitliche Anlagefläche 13 nach außen weg, so dass auch die Distanzeinrichtung 16 und insbesondere der Distanzabschnitt 19 wenigstens abschnittsweise nach außen federt. So wird ausreichend Platz für die Filtereinrichtungen 4, 5, 21 in dem Aufnahmeabschnitt 3 zur Verfügung gestellt.In the right in Figure 4 The installation situation shown, the filter devices 4, 5, 21 are made somewhat wider, so that only a small gap would arise. The spring device 14 then springs away through the lateral contact surface 13 so that the spacer device 16 and in particular the spacer section 19 also springs outward at least in sections. In this way, sufficient space for the filter devices 4, 5, 21 is made available in the receiving section 3.

In Figur 5 ist noch einmal rein schematisch und beispielhaft die Distanzeinrichtung 16 dargestellt, wie sie in Figur 3 in die Federeinrichtung 14 eingesetzt ist. Hier erkennt man den Befestigungsabschnitt 18 und den Distanzabschnitt 19. Dabei weist der Distanzabschnitt 19 eine Stärke 20 auf, die je nach anzunehmender maximaler Differenz 11 unterschiedlich ausgeführt sein kann. Dabei hängt die Stärke 20 des Distanzabschnitts 19 wesentlich von den zu erwartenden Fertigungstoleranzen sowohl der einzelnen Filtereinrichtungen 4, 5, 21, als auch von den Fertigungstoleranzen der Gehäuseeinrichtung 2 ab. Sind an beiden Seiten des Aufnahmeabschnitts 3 Justiereinrichtungen vorgesehen, kann die Stärke 20 des Distanzabschnitts 19 der Distanzeinrichtung 16 auf die Hälfte der maximal zu erwartenden Differenz 11 eingestellt werden.In Figure 5 the spacer device 16 is shown again purely schematically and by way of example, as shown in FIG Figure 3 is inserted into the spring device 14. The fastening section 18 and the spacer section 19 can be seen here. The spacer section 19 has a thickness 20 which, depending on the maximum difference 11 to be assumed, can be designed differently. The thickness 20 of the spacer section 19 depends essentially on the expected manufacturing tolerances both of the individual filter devices 4, 5, 21 and on the manufacturing tolerances of the housing device 2. If adjustment devices are provided on both sides of the receiving section 3, the thickness 20 of the spacer section 19 of the spacer device 16 can be set to half the maximum difference 11 to be expected.

In Figur 6 sieht man eine erfindungsgemäße Filtereinrichtung 1 in einer rein schematischen geschnittenen Ansicht. Dargestellt sind die Filtereinrichtungen 4, 5, 21 und die Gehäuseeinrichtung 2, welche einen Aufnahmeabschnitt 3 zur Verfügung stellt, an welchem eine Filterfläche 6 ausgebildet werden kann. Die Filterfläche 6 wird in dem hier gezeigten Ausführungsbeispiel durch drei Filtereinrichtungen 4, 5, 21 gebildet, welche nebeneinander in dem Aufnahmeabschnitt 3 angeordnet sind.In Figure 6 one can see a filter device 1 according to the invention in a purely schematic sectional view. The filter devices 4, 5, 21 and the housing device 2, which provides a receiving section 3 on which a filter surface 6 can be formed, are shown. In the exemplary embodiment shown here, the filter surface 6 is formed by three filter devices 4, 5, 21 which are arranged next to one another in the receiving section 3.

An den Aufnahmeabschnitt 3 bzw. an die Filterfläche 6 schließt sich in dem hier gezeigten Ausführungsbeispiel ein Ansaugbereich 35 mit einer Gebläseeinrichtung an, welche aufsteigende Kochschwaden durch die Filtereinrichtungen 4, 5, 21 ins Innere der Filtervorrichtung 1 saugt.In the exemplary embodiment shown here, a suction area 35 with a blower device connects to the receiving section 3 or to the filter surface 6, which sucks rising boiling steam through the filter devices 4, 5, 21 into the interior of the filter device 1.

Damit eine im Wesentlichen vollständig geschlossene Filterfläche 6 zur Verfügung gestellt wird, ist nach dieser Ausführungsform erfindungsgemäß vorgesehen, dass an den einander zugewandten Rahmenabschnitten 27 zweier benachbarter Filtereinrichtungen 4, 5, 21 Abdeckeinrichtungen 50 angeordnet sind. Hierdurch wird erreicht, dass zwischen den Filtereinrichtungen 4, 5, 21 kein strömungsdurchlässiger Spalt entstehen kann, durch den aufsteigender Kochschwaden ungefiltert in die Gehäuseeinrichtung 2 gelangen könnte.In order to provide a substantially completely closed filter surface 6, according to this embodiment it is provided according to the invention that cover devices 50 are arranged on the mutually facing frame sections 27 of two adjacent filter devices 4, 5, 21. This ensures that no flow-permeable gap can arise between the filter devices 4, 5, 21 through which rising boiling steam could reach the housing device 2 unfiltered.

In Figur 7 ist eine rein schematische Darstellung einer ersten Variante der Ausgestaltung Abdeckeinrichtungen 50 gezeigt. Bei dieser Variante sind an den Rahmenabschnitten 27 einer Filtereinrichtung 5 jeweils Abdeckeinrichtungen 50 angeordnet. Die Abdeckeinrichtungen 50 sind vorzugsweise einteilig mit den Rahmenabschnitten 27 ausgebildet oder dauerhaft mit den Rahmenabschnitten 27, beispielsweise mittels Kleben, verbunden. Die Abdeckeinrichtungen 50 erstrecken sich dabei soweit über die Längsausdehnung 22 der filtereinrichtung 5, dass ein Spalt zwischen zwei benachbarten Filtereinrichtungen 4, 5, 21 von den Abdeckeinrichtungen 50 überdeckt ist.In Figure 7 a purely schematic representation of a first variant of the embodiment of covering devices 50 is shown. In this variant, cover devices 50 are arranged on the frame sections 27 of a filter device 5. The cover devices 50 are preferably designed in one piece with the frame sections 27 or are permanently connected to the frame sections 27, for example by means of gluing. The cover devices 50 extend over the longitudinal extent 22 of the filter device 5 to such an extent that a gap between two adjacent filter devices 4, 5, 21 is covered by the cover devices 50.

In Figur 8 ist eine rein schematische Darstellung einer zweiten Variante der Ausgestaltung der Abdeckeinrichtungen 50 gezeigt. Die Abdeckeinrichtungen 50 sind an der Unterseite 24 der Filtervorrichtung 1 angeordnet und wie bei der ersten Variante einteilig mit den Rahmenabschnitten 27 ausgebildet oder dauerhaft mit den Rahmenabschnitten 27, beispielsweise mittels Kleben, Schweißen oder Nieten, verbunden. Darüber hinaus weist jede der Abdeckeinrichtungen 50 der zweiten Variante zumindest einen Dauermagneten 56 auf. Jeder der Dauermagnete 56 ist einer der Verbindungspartner 54, 55 einer Verbindungseinrichtung 53. Mittels der Verbindungseinrichtungen 53 werden die Abdeckeinrichtungen 50 strömungsdicht an den Rahmenabschnitten 27 benachbarter Filtereinrichtungen 4, 5 oder an der Gehäuseeinrichtung 2 angelegt. In den Rahmenabschnitten 27 benachbarter Filtereinrichtungen 4, 5 oder in der Gehäuseeinrichtung 2 ist als ein anderer der Verbindungspartner 54, 55 der Verbindungseinrichtung 53 ein gegenpolig angeordneter Dauermagnet 56 oder ein magnetisches Material vorgesehen.In Figure 8 a purely schematic representation of a second variant of the configuration of the cover devices 50 is shown. The cover devices 50 are arranged on the underside 24 of the filter device 1 and, as in the first variant, are formed in one piece with the frame sections 27 or are permanently connected to the frame sections 27, for example by means of gluing, welding or riveting. In addition, each of the cover devices 50 of the second variant has at least one permanent magnet 56. Each of the permanent magnets 56 is one of the connection partners 54, 55 of a connection device 53. By means of the connection devices 53, the cover devices 50 are applied in a flow-tight manner to the frame sections 27 of adjacent filter devices 4, 5 or to the housing device 2. In the frame sections 27 of adjacent filter devices 4, 5 or in the housing device 2, a permanent magnet 56 arranged in opposite polarity or a magnetic material is provided as another of the connection partners 54, 55 of the connection device 53.

In Figur 9 ist eine schematische Darstellung einer dritten Variante der Ausgestaltung der Abdeckeinrichtungen 50 mit Dauermagneten 56 als Teil einer Verbindungseinrichtung 53 gezeigt. Bei dieser Variante sind die Abdeckeinrichtungen 50 auf einer dem Ansaugbereich 35 zugewandten Seite der Filtereinrichtungen 4, 5 angeordnet und liegen auf den Filtereinrichtungen 4, 5, 21 und/oder dem Aufnahmeabschnitt 3 auf. Die Abdeckeinrichtungen 50 welche den Spalt zweier benachbarter Filtereinrichtungen 4, 5 überbrücken umfassen zwei Dauermagneten 56 jeweils einen für eine Verbindungseinrichtung mit einem der benachbarten Filtereinrichtungen 4, 5. Die an dem Aufnahmeabschnitt 3 angeordneten Abdeckeinrichtungen 50 sind formschlüssig, strömungsdicht und zumindest in eine Richtung translatorisch beweglich 62 mit der Gehäuseeinrichtung 2 verbunden. Hierdurch wird der Austausch der Filtereinrichtungen 4, 5 erleichtert, gleichzeitig liegen die Abdeckeinrichtungen 50 durch die auf sie wirkende Schwerkraft und insbesondere durch die Magnetkraft 63 der mit einem Dauermagneten 56 ausgestatteten Verbindungseinrichtung 53 nach der Montage der benachbarten Filtereinrichtungen 4, 5 an diesem strömungsdicht an.In Figure 9 a schematic representation of a third variant of the configuration of the cover devices 50 with permanent magnets 56 as part of a connecting device 53 is shown. In this variant, the cover devices 50 are arranged on a side of the filter devices 4, 5 facing the suction area 35 and rest on the filter devices 4, 5, 21 and / or the receiving section 3. The cover devices 50, which bridge the gap between two adjacent filter devices 4, 5, comprise two permanent magnets 56 each one for a connection device with one of the adjacent filter devices 4, 5. The cover devices 50 arranged on the receiving section 3 are interlocking, flow-tight and translationally movable in at least one direction 62 is connected to the housing device 2. This makes it easier to replace the filter devices 4, 5; at the same time, the cover devices 50 rest against the adjacent filter devices 4, 5 in a flow-tight manner due to the force of gravity acting on them and, in particular, the magnetic force 63 of the connecting device 53 equipped with a permanent magnet 56.

In Figur 10 ist eine rein schematische Darstellung einer vierten Variante der Ausgestaltung einer Abdeckeinrichtung 50 mit einer Halteeinrichtung 52 gezeigt. Die Abdeckeinrichtung 50 umfasst ein Abdeckelement 51 und eine Halteeinrichtung 52 für das Abdeckelement 51. Hier weiter nicht dragestellt ist, wie die Halteeinrichtung 51 an der Gehäuseeinrichtung 2 befestigt ist. Das Abdeckelement 51 ist lösbar mit der Halteeinrichtung 52 verbunden. Hierzu ist eine Verbindungseinrichtung 53 derart ausgestaltet, dass ein erster der Verbindungspartner 54, 55 an dem Abdeckelement 51 und ein weiterer der Verbindungspartner 54, 55 an der Halteeinrichtung 52 angeordnet ist. Dabei sind die Verbindungspartner 54, 55 als eine Nut 57 mit einem Rastvorsprung 58 und eine in der Nut 57 anordenbare Feder 59 mit einem Rastvorsprung 58 ausgeführt. Durch die gegenseitig hinterschneidenen Rastvorsprünge 58 sind Nut 57 und Feder 59 ineinander gehalten. Nut 57 und Feder 59 sind derart ausgestaltet, dass diese zumindest in einer Richtung translatorisch beweglich 62 sind. Diese Beweglichkeit 62 ermöglicht ein Ausweichen der von den Filtereinrichtungen 4, 5, 21 unabhängigen Abdeckeinrichtung 50 bei der Montage und ein strömungsdichtes Anliegen der Abdeckeinrichtung 50 an den Filtereinrichtungen 4, 5, 21 im montierten Zustand.In Figure 10 a purely schematic representation of a fourth variant of the configuration of a cover device 50 with a holding device 52 is shown. The cover device 50 comprises a cover element 51 and a holding device 52 for the cover element 51. It is not shown here how the holding device 51 is attached to the housing device 2. The cover element 51 is detachably connected to the holding device 52. For this purpose, a connection device 53 is designed such that a first of the connection partners 54, 55 is arranged on the cover element 51 and a further one of the connection partners 54, 55 is arranged on the holding device 52. The connection partners 54, 55 are formed as a groove 57 with a latching projection 58 and a tongue 59 that can be arranged in the groove 57 with a Latching projection 58 executed. The groove 57 and tongue 59 are held in one another by the mutually undercut locking projections 58. Groove 57 and tongue 59 are designed in such a way that they are translationally movable 62 at least in one direction. This mobility 62 enables the cover device 50, which is independent of the filter devices 4, 5, 21, to evade during assembly and the cover device 50 rests against the filter devices 4, 5, 21 in a flow-tight manner in the assembled state.

In Figur 11 ist eine rein schematische Darstellung der Halteeinrichtung 52 in einer perspektivischen Ansicht gezeigt. Die Halteeinrichtung 52 weist an einer Seite einen als Nut 57 ausgeführten Verbindungspartner 54 auf. An einer weiteren Seite hat die Halteeinrichtung 52 einen Befestigungsvorsprung 64 zur Befestigung der Halteeinrichtung 52 an der Gehäuseeinrichtung 2, insbesondere an dem Aufnahmeabschnitt 3 der Gehäuseeinrichtung 2 auf.In Figure 11 a purely schematic representation of the holding device 52 is shown in a perspective view. The holding device 52 has on one side a connection partner 54 designed as a groove 57. On a further side, the holding device 52 has a fastening projection 64 for fastening the holding device 52 on the housing device 2, in particular on the receiving section 3 of the housing device 2.

In Figur 12 ist eine rein schematische Darstellung eines Abdeckelements 51 der Abdeckeinrichtung 50 in einer perspektivischen Ansicht gezeigt. Das Abdeckelement 51 hat einen als Feder 59 ausgeführten Verbindungspartner 55, welcher zum Eingriff in die Nut 57 der Halteeinrichtung 52 vorgesehen ist.In Figure 12 a purely schematic representation of a cover element 51 of the cover device 50 is shown in a perspective view. The cover element 51 has a connection partner 55 designed as a tongue 59, which is provided for engagement in the groove 57 of the holding device 52.

In den Figuren 13 und 14 sind in rein schematischen Darstellungen eine fünfte und eine sechste Variante der Abdeckeinrichtung 50 gezeigt. Die Beweglichkeit 62 der Abdeckeinrichtung 50 ist mittels eines Doppelpfeiles angedeutet. Das Abdeckelement 51 der Abdeckeinrichtung 50 hat eine Breite 60 die wenigstens einer größten anzunehmenden Differenz 11 der Längsausdehnungen 9, 10, 22 der Filtereinrichtungen 4, 5, 21 entspricht. In den dargestellten Varianten ist die Breite 60 des Abdeckelementes 51 deutlich größer. In der in Figur 13 gezeigten fünften Variante entspricht die Breite 60 des Abdeckelementes 51 der Rahmenbreite 61 eines Rahmenabschnittes 27. In der in Figur 14 gezeigten sechsten Variante ist die Breite 60 des Abdeckelementes 51 größer als die zwei Rahmenbreiten 61 der benachbart angeordneten Rahmenabschnitte 27 zuzüglich der größten anzunehmenden Differenz 11.In the Figures 13 and 14 A fifth and a sixth variant of the covering device 50 are shown in purely schematic representations. The mobility 62 of the cover device 50 is indicated by means of a double arrow. The cover element 51 of the cover device 50 has a width 60 which corresponds to at least one greatest difference 11 to be assumed in the longitudinal dimensions 9, 10, 22 of the filter devices 4, 5, 21. In the variants shown, the width 60 of the cover element 51 is significantly larger. In the in Figure 13 The fifth variant shown corresponds to the width 60 of the cover element 51 of the frame width 61 of a frame section 27. In the FIG Figure 14 The sixth variant shown, the width 60 of the cover element 51 is greater than the two frame widths 61 of the adjacently arranged frame sections 27 plus the greatest difference 11 to be assumed.
