Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft einen Haushalts-Dunstabzug mit einer Haube zum Auffangen von Dunst, einem Kamin über der Haube, einem im Kamin angeordneten Gebläse sowie einer im Kamin angeordneten Filteranordnung, wobei die Filteranordnung mehrere Filterplatten aufweist.The invention relates to a household extractor with a hood for catching haze, a chimney over the hood, a fan arranged in the chimney and a filter arrangement arranged in the chimney, wherein the filter arrangement has a plurality of filter plates.

Hintergrundbackground

Ein Dunstabzug dieser Art wird in EP 1 705 430 beschrieben. Er besitzt eine unten offene Haube zum Auffangen des von einer Kochstelle aufsteigenden Dunstes. Über der Haube ist ein Kamin angeordnet, in welchem ein Gebläse sowie eine Filteranordnung vorgesehen sind. Die Filteranordnung weist mehrere Filterplatten auf.A fume hood of this type will be in EP 1 705 430 described. It has a hood open at the bottom to catch the mist rising from a cooking place. Above the hood a fireplace is arranged, in which a blower and a filter arrangement are provided. The filter assembly has a plurality of filter plates.

Aus der EP 2 375 173 A1 ist eine Abzugseinrichtung gezeigt, bei welcher Filterkanäle wechselweise einlassseitig und auslassseitig verschlossen sind.From the EP 2 375 173 A1 a discharge device is shown in which filter channels are alternately closed on the inlet side and the outlet side.

In der EP 1563 889 A1 ist ein filternder Abscheider für partikelbelastete Gase gezeigt, welcher ein blockartiges Filterelement umfasst.In the EP 1563 889 A1 For example, there is shown a filtering particulate gas separator which comprises a block-like filter element.

Darstellung der ErfindungPresentation of the invention

Es stellt sich die Aufgabe, einen Haushalts-Dunstabzug dieser Art bereitzustellen, der eine verbesserte Filterwirkung aufweist. Diese Aufgabe wird vom Dunstabzug gemäss Anspruch 1 gelöst.It has as its object to provide a household extractor of this type, which has an improved filtering effect. This object is achieved by the extractor hood according to claim 1.

Demgemäss weist die Filteranordnung also mindestens einen Satz von mindestens vier voneinander beabstandeten, zueinander parallelen, vertikalen Filterplatten auf gleicher Höhe auf. Zwischen diesen Filterplatten werden mindestens eine nach unten offene Eingangskammer und mindestens eine nach oben offene Ausgangskammer gebildet. Die in die Eingangskammer eingesaugte Luft tritt durch eine der Filterplatten, gelangt so in die Ausgangskammer und wird von dort zum Gebläse weitergeführt.Accordingly, the filter assembly thus has at least one set of at least four mutually spaced, mutually parallel, vertical filter plates at the same height. Between these filter plates at least one downwardly open input chamber and at least one upwardly open output chamber are formed. The sucked into the inlet chamber air passes through one of the filter plates, passes so in the output chamber and is continued from there to the blower.

Zusätzlich wird zwischen den erwähnten mindestens vier vertikalen Filterplatten noch mindestens eine Kammer gebildet, welche vorzugsweise ebenfalls als nach oben offene Ausgangskammer ausgebildet ist. In diesem Falle ist zwischen den beiden Ausgangskammern vorteilhaft eine Eingangskammer vorgesehen. Dies hat den Vorteil, dass Luft von der Kochstelle auch von aussen über vertikale Filterplatten in die Ausgangskammern treten kann.In addition, between the mentioned at least four vertical filter plates still at least one chamber is formed, which is preferably also designed as an upwardly open output chamber. In this case, an input chamber is advantageously provided between the two output chambers. This has the advantage that air from the hob can also pass from the outside via vertical filter plates in the output chambers.

Aufgrund der gleichen Überlegung ist es auch von Vorteil, wenn jede Eingangskammer horizontal auf allen Seiten an mindestens eine Ausgangskammer angrenzt. Auch dann liegt die Eingangskammer innen, so dass Luft von der Kochstelle auch von aussen über vertikale Filterplatten in die Ausgangskammer(n) treten kann.Due to the same consideration, it is also advantageous if each input chamber is horizontally adjacent to at least one output chamber on all sides. Even then, the entrance chamber is inside, so that air from the hob can also from the outside via vertical filter plates in the output chamber (s) can occur.

Anspruchsgemäss sind mindestens zwei Sätze zueinander paralleler, vertikaler Filterplatten vorgesehen. Die Filterplatten der beiden Sätze sind quer zueinander angeordnet. Auf diese Weise können mindestens neun Kammern zwischen den Platten gebildet werden. Vorzugsweise stehen dabei die Platten der beiden Sätze senkrecht zueinander, so dass rechteckige oder quadratische Kammern entstehen. Sie können jedoch grundsätzlich auch unter 60° bzw. 120° zueinander stehen, um dreieckige oder sechseckige Kammern zu bilden.According to the claim, at least two sets of parallel, vertical filter plates are provided. The filter plates of the two sets are arranged transversely to each other. In this way, at least nine chambers can be formed between the plates. Preferably, the plates of the two sets are perpendicular to each other, so that rectangular or square chambers arise. However, they can in principle also be below 60 ° or 120 ° to each other to form triangular or hexagonal chambers.

Wege zur Ausführung der ErfindungWays to carry out the invention Definitionen:definitions:

Die Richtungen "unten" und "oben" werden durch die Richtung des Luftstroms in der Filteranordnung definiert, indem der Luftstrom die Filteranordnung von unten nach oben durchläuft. Demgemäss folgt, dass die Haube unterhalb des Kamins angeordnet ist.The directions "bottom" and "top" are defined by the direction of the air flow in the filter assembly as the air flow passes through the filter assembly from bottom to top. Accordingly, it follows that the hood is located below the chimney.

Die Angaben "horizontal" und "vertikal" sind in gleicher Weise definiert. Demgemäss ist eine Filterplatte vertikal angeordnet, wenn sie parallel zur Längsrichtung des Kamins verläuft, und horizontal, wenn sie senkrecht dazu verläuft.The terms "horizontal" and "vertical" are defined in the same way. Accordingly, a filter plate is arranged vertically when it is parallel to the longitudinal direction of the chimney, and horizontally when it is perpendicular thereto.

Fig. 1 zeigt einen Dunstabzug mit einer nach unten offenen Haube 1, oberhalb der ein Kamin 2 angeordnet ist. Im Kamin 2 ist ein Gebläse 3 vorgesehen, sowie eine Filteranordnung 4. Das Gebläse 3 fördert die Luft bzw. den Dunst von der Haube 1 durch die Filteranordnung 4 und gibt diese durch eine Austrittsöffnung 5 ab. Fig. 1 shows a fume hood with a downwardly open hood 1, above which a chimney 2 is arranged. In the chimney 2, a fan 3 is provided, and a filter assembly 4. The fan 3 promotes the air or the haze of the hood 1 through the filter assembly 4 and outputs it through an outlet opening 5 from.

Beim Dunstabzug kann es sich um einen offenen Dunstabzug handeln, der die von der Filteranordnung 4 gereinigte Luft wieder an den Raum abgibt, oder um eine geschlossenen Dunstabzug, der die gereinigte Luft an ein Abluftsystem abgibt, über welches diese aus dem Raum geführt und z.B. ins Freie abgegeben wird.The extractor may be an open extractor which returns the air cleaned by the filter assembly 4 back to the room, or a closed extractor which discharges the cleaned air to an exhaust system via which it passes out of the room and e.g. is released to the outside.

Fig. 2 - 6 zeigen eine erste Ausführung der Filteranordnung 4. Deren Aufbau wird im Folgenden beschrieben. Fig. 2-6 show a first embodiment of the filter assembly 4. The structure will be described below.

Grundsätzlich besitzt die Filteranordnung 4 einen oberen und einen unteren Abschnitt 4a bzw. 4b. Die beiden Abschnitte besitzen im Wesentlichen den gleichen Aussendurchmesser. Der obere Abschnitt 4a bildet einen Gebläseraum 6 (Fig. 5, 6), in welchem das Gebläse 3 angeordnet ist. Der untere Abschnitt 4b bildet einen Filterbereich, in welchem ein Grossteil der Luft gefiltert wird.Basically, the filter assembly 4 has an upper and a lower portion 4a and 4b. The two sections have substantially the same outer diameter. The upper portion 4a forms a fan chamber 6 (FIG. Fig. 5, 6 ), in which the blower 3 is arranged. The lower portion 4b forms a filter area in which a majority of the air is filtered.

Im unteren Abschnitt sind die oben erwähnten vertikalen Filterplatten 8, 9 vorgesehen, die alle auf gleicher Höhe angeordnet sind. In der gezeigten Ausführung bilden diese Filterplatten ein erstes, inneres Modul 10 aus vier senkrecht zueinander angeordneten inneren Filterplatten 8 sowie ein äusseres Modul 11 aus vier senkrecht zueinander angeordneten äusseren Filterplatten 9 (Fig. 6). Das zweite Modul 11 umgibt das erste Modul 10. Jedes Modul 10, 11 wird von jeweils vier zueinander senkrecht stehender Filterplatten 8 bzw. 9 gebildet und besitzt rechteckigen, vorzugsweise quadratischen Querschnitt. Denkbar ist jedoch auch, dass die Module jeweils aus drei oder mehr als vier Filterplatten gebildet werden und z.B. drei- oder sechseckigen Querschnitt besitzen.In the lower section, the above-mentioned vertical filter plates 8, 9 are provided, which are all arranged at the same height. In the embodiment shown, these filter plates form a first, inner module 10 of four mutually perpendicular inner filter plates 8 and an outer module 11 of four mutually perpendicular outer filter plates 9 (FIGS. Fig. 6 ). The second module 11 surrounds the first module 10. Each module 10, 11 is formed by four mutually perpendicular filter plates 8 and 9 and has a rectangular, preferably square cross-section. However, it is also conceivable that the modules are each formed from three or more than four filter plates and, for example, have a triangular or hexagonal cross-section.

Das erste Modul 10 umgibt eine Eingangskammer 14 (vgl. Fig. 4), welche gegen unten, d.h. zur Haube 1 hin, offen ist, und gegen oben von einem Deckel 15 (Fig. 5, 6) abgeschlossen wird. Der Deckel 15 kann luftundurchlässig oder als Filter ausgestaltet sein.The first module 10 surrounds an input chamber 14 (see FIG. Fig. 4 ), which is open towards the bottom, ie toward the hood 1, and upwardly from a cover 15 (FIG. Fig. 5, 6 ) is completed. The lid 15 may be impermeable to air or designed as a filter.

Zwischen den Filterplatten 8 bzw. 9 des ersten und dem zweiten Moduls wird mindestens eine Ausgangskammer 16 gebildet (Fig. 5). Diese ist nach oben, d.h. zum Lüfter 3 hin, offen, nach unten aber durch einen Boden 17 geschlossen. Der Boden 17 kann luftundurchlässig oder als Filter ausgestaltet sein.Between the filter plates 8 and 9 of the first and the second module at least one output chamber 16 is formed ( Fig. 5 ). This is upwards, ie toward the fan 3, open, but closed down by a bottom 17. The bottom 17 may be impermeable to air or designed as a filter.

Wie weiter aus Fig. 5 ersichtlich, sind die Platten 8 bzw. 9 beabstandet von der Wand 18 des Kamins 2 angeordnet, so dass sich zwischen der Wand 18 und den Platten ein Steigkanal 19 für Dunst von der Haube 1 bildet.How farther Fig. 5 can be seen, the plates 8 and 9 spaced from the wall 18 of the chimney 2 are arranged so that forms a riser 19 for the vapor from the hood 1 between the wall 18 and the plates.

Der Gebläseraum 6 ist oberhalb der vertikalen Filterplatten 8, 9 angeordnet. Mindestens eine der vertikalen Aussenwände des Gebläseraums 6 wird von einer Gebläseraum-Filterplatte 20 gebildet. Diese ist beabstandet von der Wand 19 angeordnet, so dass sich der Steigkanal 19 entlang der Aussenseite der Gebläseraum-Filterplatte 20 nach oben fortsetzt.The blower chamber 6 is arranged above the vertical filter plates 8, 9. At least one of the vertical outer walls of the fan chamber 6 is formed by a fan filter plate 20. This is spaced from the wall 19, so that the riser 19 continues along the outside of the fan filter plate 20 upwards.

Mindestens eine weitere vertikale Aussenwand des Gebläseraums wird von einem luftundurchlässigen Wandabschnitt 22 gebildet. Dies hat den Vorteil, dass die Aussenwand in diesem Bereich dünner gestaltet werden kann, so dass mehr Platz für das Gebläse 3 bleibt.At least one further vertical outer wall of the fan chamber is formed by an air-impermeable wall section 22. This has the advantage that the outer wall can be made thinner in this area, so that more space for the fan 3 remains.

Im Betrieb tritt der angesaugte Dunst, wie in Fig. 5 illustriert, von der Haube in die Eingangskammer 14 ein, von wo er über die vertikalen Filterplatten 8 des ersten Moduls in die Ausgangskammer 16 treten kann. Von der Ausgangskammer 16 steigt die Luft nach oben in den Gebläseraum 6 und somit zum Gebläse 3. Gleichzeitig steigt die Luft von der Haube 1 auch in den Steigkanal 19, von wo sie entweder von aussen in die Ausgangskammer 16 oder direkt in den Gebläseraum 6 treten kann.In operation, the aspirated vapor, as in Fig. 5 illustrated, from the hood in the input chamber 14, from where it can pass through the vertical filter plates 8 of the first module in the output chamber 16. From the outlet chamber 16, the air rises up into the fan chamber 6 and thus to the blower 3. At the same time the air from the hood 1 also rises into the riser 19, from where they either enter the outlet chamber 16 from outside or directly into the blower chamber 6 can.

In der gezeigten Ausführung ist zwischen dem oberen Bereich 4a und dem unteren Bereich 4b ein mittlerer Bereich 4c ausgebildet, welcher von vier Zwischenbereichs-Filterplatten 24 gebildet wird. Hierdurch kann der Gebläseraum 6 vergrössert werden.In the embodiment shown, a middle region 4 c is formed between the upper region 4 a and the lower region 4 b, which is formed by four intermediate-area filter plates 24. As a result, the fan chamber 6 can be increased.

Wie insbesondere aus Fig. 6 ersichtlich, bestehen die Filterplatten 8, 9, 20, 24 vorzugsweise aus jeweils aus identischen, vorzugsweise quadratischen Filterelementen 25. In der gezeigten Ausführung besitzen die Filterplatten 8 des ersten Moduls 10 jeweils einen Drittel der Filterfläche der Filterplatten 9 des zweiten Moduls. Somit können die Filterplatten 9 aus dreimal mehr Filterelementen 25 aufgebaut werden als die Filterplatten 8 des ersten Moduls. In der vorliegenden Ausführung sind die Filterplatten 8 des ersten Moduls 10 jeweils aus drei Filterelementen 25 aufgebaut und die Filterplatten 9 des zweiten Moduls 11 aus neun.As in particular from Fig. 6 As can be seen, the filter plates 8, 9, 20, 24 preferably each consist of identical, preferably square filter elements 25. In the embodiment shown, the filter plates 8 of the first module 10 each have one third of the filter surface of the filter plates 9 of the second module. Thus, the filter plates 9 can be constructed of three times more filter elements 25 than the filter plates 8 of the first module. In the present embodiment, the filter plates 8 of the first module 10 are each constructed of three filter elements 25 and the filter plates 9 of the second module 11 of nine.

Zur Befestigung der Filteranordnung 4 ist beispielsweise ein Rahmen 28 aus Profilstangen vorgesehen. Der Rahmen 28 ist am Deckel 29 des Kamins 2 befestigt und hängt im Kamin 2 nach unten. Die äusseren Filterplatten 9, 20 und 24, die an den Steigraum 19 angrenzen, sind direkt in den Rahmen 28 eingehängt. Zur Befestigung des ersten Moduls 10 am zweiten Modul 11 sind Streben 30 (Fig. 4, 6) vorgesehen, welche sich von der Unterkante des ersten Moduls zur Unterkante des zweiten Moduls erstrecken und die dort im Rahmen 28 eingehängt sind.For attachment of the filter assembly 4, for example, a frame 28 is provided from profiled bars. The frame 28 is fixed to the lid 29 of the chimney 2 and hangs in the chimney 2 down. The outer filter plates 9, 20 and 24, which adjoin the riser 19, are mounted directly in the frame 28. For attachment of the first module 10 on the second module 11 are struts 30 (FIG. Fig. 4, 6 ), which extend from the lower edge of the first module to the lower edge of the second module and which are suspended there in the frame 28.

Fig. 7 - 11 zeigen eine zweite Ausführung eines Dunstabzugs, die sich gegenüber der ersten Ausführung primär in Anordnung und Aufbau der Filterplatten unterscheidet. Fig. 7 - 11 show a second embodiment of a fume hood, which differs from the first embodiment primarily in the arrangement and construction of the filter plates.

Wiederum besitzt die Filteranordnung 4 einen oberen und einen unteren Abschnitt 4a bzw. 4b, deren Funktionen denjenigen der ersten Ausführung entsprechen.Again, the filter assembly 4 has upper and lower portions 4a and 4b, respectively, whose functions correspond to those of the first embodiment.

In der gezeigten Ausführung sind im unteren Abschnitt insgesamt vier Sätze von Filterplatten 9a - 9d, 9e - 9h, 9i - 91, 9m - 9p vorgesehen. Zwei dieser Sätze werden als "obere Sätze" bezeichnet und umfassen einen ersten oberen Filtersatz 9a - 9d sowie einen zweiten oberen Filtersatz 9e - 9h. Die beiden übrigen Sätze werden als "untere Sätze" bezeichnet und umfassen einen ersten unteren Filtersatz 9i - 91, sowie einen zweiten unteren Filtersatz 9m - 9p.In the embodiment shown, a total of four sets of filter plates 9a-9d are in the lower portion, 9e - 9h, 9i - 91, 9m - 9p. Two of these sets are referred to as "upper sets" and comprise a first upper filter set 9a-9d and a second upper filter set 9e-9h. The remaining two sets are referred to as "lower sets" and include a first lower filter set 9i-91 and a second lower filter set 9m-9p.

Die Filterplatten jedes einzelnen Satzes sind zueinander parallel und vorzugsweise gleichabständig angeordnet. In der gezeigten Ausführung sind pro Satz jeweils vier Filterplatten vorhanden.The filter plates of each set are arranged parallel to each other and preferably gleichabständig. In the illustrated embodiment, four filter plates are available per set.

Für die oberen Filtersätze 9a - 9h gilt, dass die Filterplatten alle auf derselben Höhe angeordnet sind. Die Filterplatten der beiden Sätze 9a - 9d bzw. 9e - 9h stehen in der gezeigten Ausführung senkrecht zueinander und kreuzen sich, so dass sie in ihren Zwischenräumen insgesamt neun rechteckige Kammerabschnitte bilden. Die Filterplatten 9a - 9d weisen jeweils von ihrem oberen Rand vertikal nach innen (d.h. unten) verlaufende Ausnehmungen 32 auf, während die Filterplatten 9e - 9h jeweils von ihrem unteren Rand vertikal nach innen (d.h. oben) verlaufende Ausnehmungen 32 aufweisen. Die Breite der Ausnehmungen 32 ist jeweils so bemessen, dass sie im Wesentlichen der Dicke der Filterplatten entspricht, so dass die Filterplatten der beiden Sätze ineinander gesteckt werden können, derart, dass sie sich im Bereich der Ausnehmungen kreuzen.For the upper filter sets 9a-9h, the filter plates are all arranged at the same height. The filter plates of the two sets 9a - 9d and 9e - 9h are perpendicular to each other in the embodiment shown and intersect, so that they form a total of nine rectangular chamber sections in their interstices. The filter plates 9a-9d have respective recesses 32 extending vertically inwardly (i.e., below) from their upper edges, while the filter plates 9e-9h have recesses 32 extending vertically inwardly (i.e., above) from their lower edges, respectively. The width of the recesses 32 is in each case dimensioned such that it corresponds substantially to the thickness of the filter plates, so that the filter plates of the two sets can be inserted into one another such that they intersect in the region of the recesses.

Die beiden unteren Filtersätze 9i - 9p sind in gleicher Weise aufgebaut.The two lower filter sets 9i - 9p are constructed in the same way.

Aufeinandergestellt kommen die Kammerabschnitte, die von den Sätzen gebildet werden, vertikal übereinander zu liegen und bilden Eingangs- und Ausgangskammern 14 bzw. 16 (Fig. 8), deren Aufbau im Folgenden genauer beschrieben wird.Arranged come the chamber sections, which are formed by the sentences to lie vertically above one another and form input and output chambers 14 and 16 ( Fig. 8 ), the structure of which will be described in more detail below.

Oberhalb der beiden oberen Sätze von Filterplatten ist eine obere Blende 33 vorgesehen, welche Öffnungen 34 im Bereich der Ausgangskammern 16 aufweist, während sie im Bereich der Eingangskammern 14 geschlossen ist. Unterhalb der beiden unteren Sätze von Filterplatten ist eine untere Blende 35 vorgesehen, welche Öffnungen 36 im Bereich der Eingangskammern 14 aufweist, während sie im Bereich der Ausgangskammern 16 geschlossen ist.Above the two upper sets of filter plates, an upper aperture 33 is provided, which has openings 34 in the region of the outlet chambers 16, while it is closed in the region of the inlet chambers 14. Below the two lower sets of filter plates, a lower aperture 35 is provided, which has openings 36 in the region of the inlet chambers 14, while it is closed in the region of the outlet chambers 16.

Auf diese Weise entstehen insgesamt vier nach unten geöffnete Eingangskammern 14 sowie fünf nach oben geöffnete Ausgangskammern 16.In this way, a total of four downwardly open input chambers 14 and five upwardly open output chambers 16.

Alle Filterplatten 9a - 9p sind identisch aufgebaut und miteinander vertauschbar. Nebst den bereits erwähnten Ausnehmungen 32 weisen sie hierzu an ihren vertikalen Seitenkanten jeweils ineinandergreifende Abstufungen 38 auf (Fig. 11).All filter plates 9a - 9p are constructed identically and interchangeable. In addition to the recesses 32 already mentioned, they each have mutually interlocking graduations 38 on their vertical side edges (FIG. Fig. 11 ).

Der obere Abschnitt 4a ist im Wesentlichen aufgebaut wie jener der ersten Ausführung. Wiederum wird der Gebläseraum 6 von drei vertikalen Seiten von Gebläseraum-Filterplatten 20 eingefasst, während eine Aussenwand des Gebläseraums von einem luftundurchlässigen Wandabschnitt 22 gebildet wird.The upper portion 4a is basically constructed like that of the first embodiment. Again, the fan room 6 is enclosed by three vertical sides of fan room filter plates 20, while an outer wall of the fan room is formed by an air-impermeable wall portion 22.

Die Luftströmung in der zweiten Ausführung ist ähnlich wie bei der ersten Ausführung, indem die Luft über die Eingangskammern 14 oder die Steigkammern 19 in die Ausgangskammern 16 übertritt, oder indem sie über die Gebläseraum-Filterplatten 20 direkt in den Gebläseraum 6 gelangt.The air flow in the second embodiment is similar to the first embodiment, in that the air passes through the inlet chambers 14 or the riser chambers 19 into the outlet chambers 16, or passes directly into the fan chamber 6 via the fan filter plates 20.

Um die Filterplatten zu befestigen, sind im Bereich der vertikalen Kanten der Filteranordnung Führungsmittel angebracht. In der Ausführung nach Fig. 10 und 11 handelt es sich dabei um Stangen 40, welche am Deckel 29 des Kamins 2 befestigt sind und nach unten hängen. Am unteren Ende der Führungsmittel sind Sicherungsmittel vorgesehen, z.B. in Form von Muttern 42 (Fig. 9), die mit den Stangen 40 verschraubt sind.In order to secure the filter plates, guide means are mounted in the region of the vertical edges of the filter arrangement. In the execution after 10 and 11 These are rods 40, which are attached to the lid 29 of the chimney 2 and hang down. At the lower end of the guide means securing means are provided, for example in the form of nuts 42 (FIG. Fig. 9 ), which are bolted to the rods 40.

Anstelle von Stangen 40 können als Führungsmittel z.B. auch Kantenprofile 43 verwendet werden, wie sie in Fig. 8 gestrichelt dargestellt sind, welche in den Ecken des Kamin 1 befestigt werden.Instead of rods 40 can be used as a guide, for example, edge profiles 43, as in Fig. 8 dashed lines are shown, which are fastened in the corners of the chimney 1.

Die Filterplatten bzw. deren Filterelemente umfassen vorzugsweise zwei beabstandete, luftdurchlässige Deckschichten, zwischen denen das eigentliche Filtermaterial, insbesondere aus Aktivkohle, angeordnet ist.The filter plates or their filter elements preferably comprise two spaced, air-permeable cover layers, between which the actual filter material, in particular of activated carbon, is arranged.

Der untere Abschnitt 4b der Filteranordnung kann den jeweiligen Anforderungen angepasst sein, bzw. es können basierend auf demselben Design Filteranordnungen mit unterschiedlichen Ausbaustufen angeboten werden. So kann z.B. anstelle der gezeigten unteren Abschnitte 4b auch eine einfachere Anordnung vorgesehen sein, welche eine kleinere Filterfläche besitzt. Beispielsweise können die unteren zwei Sätze von Filterplatten der Ausführung nach Fig. 7 - 11 auch entfallen, und die untere Blende 35 wird angrenzend an die oberen Sätze von Filterplatten montiert, so dass die Eingangs- und Ausgangskammern nur die halbe Höhe aufweisen. In einer weiteren Variante kann der Dunstabzug auch ganz ohne den unteren Abschnitt 4b ausgeliefert werden. In diesem Falle wird die Unterseite der Gebläsekammer 6 durch eine horizontal angeordnete Filterplatte oder Verschlussplatte ersetzt.The lower section 4b of the filter arrangement can be adapted to the respective requirements, or it can be offered based on the same design filter arrangements with different configuration levels. For example, instead of the lower sections 4b shown, a simpler arrangement may be provided which has a smaller filter area. For example, the lower two sets of filter plates may be of the type Fig. 7 - 11 also omitted, and the lower panel 35 is mounted adjacent to the upper sets of filter plates, so that the input and output chambers have only half the height. In a further variant, the extractor can be delivered without the lower section 4b. In this case, the underside of the fan chamber 6 is replaced by a horizontally arranged filter plate or closure plate.

Zusammenfassend kann gesagt werden, dass der Haushalts-Dunstabzug eine Filteranordnung besitzt, welche mindestens einen Satz von vier voneinander beabstandeten, zueinander parallelen, vertikalen Filterplatten 9a - 9p auf gleicher Höhe aufweist. Zwischen den Filterplatten 9a - 9p werden mindestens eine nach unten offene Eingangskammer 14 und mindestens eine nach oben offene Ausgangskammer 16 gebildet. Dadurch wird bei kompaktem Aufbau die zur Verfügung stehende Filterfläche erhöht.In summary, it can be said that the household extractor has a filter assembly which has at least one set of four spaced, mutually parallel, vertical filter plates 9a - 9p at the same height. At least one downwardly open input chamber 14 and at least one upwardly open output chamber 16 are formed between the filter plates 9a-9p. As a result, the available filter area is increased in a compact design.

Die Zahl paralleler Filterplatten kann auch höher als vier sein, z.B. sechs oder acht, wodurch die Zahl der Eingangs- und Ausgangskammern entsprechend erhöht wird.The number of parallel filter plates can also be higher than four, e.g. six or eight, which increases the number of input and output chambers accordingly.

Während in der vorliegenden Anmeldung bevorzugte Ausführungen der Erfindung beschrieben sind, ist klar darauf hinzuweisen, dass die Erfindung nicht auf diese beschränkt ist und in auch anderer Weise innerhalb des Umfangs der folgenden Ansprüche ausgeführt werden kann.While preferred embodiments of the invention are described in the present application, it should be clearly understood that the invention is not limited thereto and in any other way within the scope of the following claims.
