Lüftungsanordnungen dieser Art sind in den verschiedensten Ausführungsformen seit langem bekannt.Ventilation arrangements of this type are in the most varied Embodiments have long been known.
Bei einer dieser Lüftungsanordnungen bestehen die Wände des Sammelkanales aus streifenförmigen Blechteilen, die über Profile aus Aluminium miteinander verbunden sind. Mit entsprechend geformten Profilen werden bei dieser bekannten Konstruktion auch die Verstärkungen im Bereich der Ränder der Kanalöffnungen gebildet. Auf diese Weise erhalten die Ränder eine hohe Stabilität und ermöglichen eine gut abdichtbare Anlage für die Einsätze, wie die Abscheider, Verschließblenden oder dergleichen. In one of these ventilation arrangements, the walls of the Collection channel from strip-shaped sheet metal parts, which over Profiles made of aluminum are interconnected. With accordingly shaped profiles are known in this Construction also the reinforcements in the area of the edges the channel openings formed. That way they get Edges have a high stability and enable a well sealable Plant for the inserts, such as the separators, closing covers or similar.
In der US-A-3 190 209 ist eine Lüftungsanordnung zur Belüftung von Räumen offenbart, mit der warme, gekühlte oder Frischluft in einen Raum, eine Halle oder dergleichen zugeführt werden kann. Die hierin gezeigte Lüftungsanordnung weist zumindest einen im wesentlichen horizontal verlaufenden, und mindestens drei Seitenwände aufweisenden Sammelkanal auf, ist aber mit einer Belüftungsquelle verbunden. Die über die gesamte Sammelkanallänge verlaufende Kanalöffnung ist mit einem Einsatzgrill zu versehen und zwar in lösbarer Weise. Die in den Figuren und der Beschreibung dargestellte Ausführungsform ist offensichtlich auf eine aus Kunststoff gespritzte Ausgestaltung gerichtet. Zwar ist auch die Verwendung von Blechteilen darin offenbart, jedoch offensichtlich nicht so, daß dort erfindungsgemäße Abkantungen von Blech als Verstärkungen dienend für einen Durchschnittsfachmann hierdurch nahegelegt sein können. Denn die gesamte Beschreibung, die auf möglicherweise als Verstärkungen anzusehende Teile gerichtet ist, beschränkt sich auf die Spritzgußausbildung. In US-A-3 190 209 a ventilation arrangement is known Ventilation of rooms revealed with the warm, chilled or Fresh air in a room, hall or the like can be supplied. The ventilation arrangement shown here has at least one substantially horizontal extending, and having at least three side walls Collecting duct on, but is with a ventilation source connected. The one running the entire length of the collecting duct Canal opening is to be provided with a grill in a detachable way. The in the figures and the description illustrated embodiment is obviously based on one Injection molded plastic directed. Although it is discloses the use of sheet metal parts therein, however obviously not so that there according to the invention Bending of sheet metal as reinforcements for one Average specialist can be suggested by this. Because the entire description that may be on as Reinforcement parts is limited on injection molding training.
Aufgabe der vorliegenden Erfindung ist es, eine vollkommen neuartige Lüftungsanordnung zu schaffen, die bei einfachem Aufbau und vergleichbarer Stabilität ohne den Einsatz von Profilen auskommt.The object of the present invention is to achieve a perfect to create novel ventilation arrangement that with simple Structure and comparable stability without the use of Profiles.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verstärkungen durch zum Sammelkanalinnenraum hin gerichtete Abkantungen einstückig aus dem Blechmaterial des Sammelkanals herausgebildet sind.This object is achieved in that the Reinforcements through towards the collecting duct interior Bends in one piece from the sheet material of the Collection channel are formed.
Der Erfindung liegt der Gedanke zugrunde, die aufwendigen Profile im Bereich der Ränder durch Abkantungen zu ersetzen. Zwar sind Abkantungen zum Zwecke der Aussteifung bzw. Versteifung in der Blechbearbeitung bereits bekannt. Es herrscht jedoch die Meinung vor, daß Abkantungen an Rändern von Blechwerkstücken keine derart präzise Ausrichtung und ebene Flächenausbildung ermöglichen, wie dies beispielsweise beim Einsatz von stranggepreßten Aluminium-Profilen möglich ist. Diese Bedenken gelten insbesondere für Abkantungen über große Längen, wie sie bei Sammelkanälen der hier zur Diskussion stehenden Art realisiert werden müssen, und insbesondere dann, wenn die Abkantungen nach innen gerichtet , d.h., in Bereichen angeordnet sind, in denen beengte Raumverhältnisse vorliegen.The invention is based on the idea that the complex Replace profiles in the area of the edges with bends. Bends are for the purpose of stiffening or stiffening in sheet metal processing already known. However, the prevailing opinion is that bevels occur Edges of sheet metal workpieces no such precise alignment and enable flat surface training like this for example when using extruded aluminum profiles is possible. These concerns apply in particular for bending over long lengths, as is the case with collecting ducts of the type under discussion here must be, and especially when the bevels facing inwards, i.e. arranged in areas in which there is limited space.
Versuche haben nun ergeben, daß sich nach innen gerichtete Abkantungen überraschenderweise auch über große Längen derart präzise ausrichten und hinsichtlich der Flächenausbildung gestalten lassen, daß auf die Anordnung von Profilen in diesem Bereich verzichtet und damit ohne funktionelle Nachteile ein erheblich vereinfachter und verbilligter Aufbau bei derartigen Lüftungsanordnungen erzielt werden kann.Experiments have now shown that inward-looking Bends, surprisingly, also over great lengths align precisely and in terms of surface area design that on the arrangement of Profiles in this area are dispensed with and therefore without functional disadvantages a considerably simplified and cheaper Structure achieved with such ventilation arrangements can be.
Grundsätzlich können die Abkantungen in Anpassung an den jeweiligen Anwendungsfall in jeder beliebigen geeigneten Weise ausgebildet sein. Eine besonders vorteilhafte Ausgestaltung ergibt sich jedoch, wenn die in dieser Weise gebildeten Verstärkungen durch zweimaliges Abkanten um jeweils 90° aus dem Material des Sammelkanales herausgebildet sind.Basically, the folds can be adapted to the respective application in any suitable Be trained. A particularly advantageous embodiment arises, however, if that in this way reinforcements formed by folding twice each formed 90 ° from the material of the collecting duct are.
Insbesondere bei Großküchen umfassen Lüftungsanordnungen der hier zur Diskussion stehenden Art nicht nur einen einzigen geraden Sammelkanal, sondern vielmehr einen Sammelkanal der aus mindestens zwei, meist in einem Winkel von 90° aneinander anschließenden geraden Kanalabschnitten zusammengesetzt ist. Bei einer derartigen Anordnung ist es vorteilhaft, wenn die Kanalabschnitte im einander zugewandten Anschlußbereich auf Gehrung geschnitten und vorzugsweise stumpf miteinander verschweißt sind. Diese Anschlußbereiche wurden bei Lüftungsanordnungen der bekannten Art bisher ebenfalls mit Verbindungsprofilen gestaltet, deren Anordnung und Abdichtung gegenüber der Sammelkanalwandung jedoch stets einen gewissen Aufwand erforderte.Especially in large kitchens include ventilation arrangements of the type under discussion here not just one single straight collecting channel, but rather one Collection channel consisting of at least two, mostly at an angle of straight duct sections adjoining one another is composed. With such an arrangement it is advantageous if the channel sections in each other facing connection area cut to miter and are preferably butt welded together. These connection areas were known in ventilation arrangements Art previously also designed with connecting profiles, their arrangement and sealing against the collecting duct wall however always required a certain effort.
Grundsätzlich können die Kanalabschnitte des Sammelkanales den jeweiligen räumlichen Gegebenheiten, insbesondere in Bezug auf die Anordnung der Kochstellen, genau angepaßt werden. In den überwiegenden Fällen wird jedoch der Sammelkanal aus vier geraden Kanalabschnitten bestehen, die zur Bildung einer rechteckigen oder quadratischen Ringkanalanordnung jeweils in einem Winkel von 90° aneinander angeschlossen sind.Basically, the channel sections of the collecting channel the respective spatial conditions, especially in Regarding the arrangement of the hotplates, precisely adapted become. In the majority of cases, however, the collection channel consist of four straight channel sections, which for Formation of a rectangular or square ring channel arrangement each at an angle of 90 ° to each other are connected.
Für besondere Anwendungen können im Bedarfsfalle jedoch auch lediglich drei gerade Kanalabschnitte zur Bildung einer U-förmigen Anordnung jeweils im Winkel von 90° aneinander angeschlossen werden.For special applications, however, if necessary also just three straight channel sections for formation a U-shaped arrangement each at an angle of 90 ° can be connected to each other.
Die erfindungsgemäße Ausgestaltung eignet sich grundsätzlich für Sammelkanäle jeglichen Querschnittes. Besonders vorteilhaft ist es jedoch, wenn der Querschnitt im wesentlichen dreieckig ist und die Kanalöffnung zur Bildung einer schräg verlaufenden, im wesentlichen zur Raummitte hin gerichteten Anordnung im Bereich der Hypotenuse des Querschnittes angeordnet ist. The configuration according to the invention is basically suitable for collecting channels of any cross-section. However, it is particularly advantageous if the cross section is essentially triangular and the channel opening for Forming an oblique, essentially to Arrangement towards the center of the room Hypotenuse of the cross section is arranged.
Im folgenden ist zur weiteren Erläuterung und zum besseren Verständnis der Erfindung ein Ausführungsbeispiel unter Bezugnahme auf die beigefügten Zeichnungen näher beschrieben und erläutert:

Bei dem in Fig. 1 dargestellten Ausführungsbeispiel einer
erfindungsgemäßen Lüftungsanordnung zur Entlüftung einer
Küche ist ein Sammelkanal vorgesehen, der aus insgesamt
vier Kanalabschnitten 1, 2, 3 und 4 zusammengesetzt ist,
die zur Bildung einer rechteckigen Ringkanalordnung jeweils
in einem Winkel von 90° aneinander angeschlossen sind.
Jeder Kanalabschnitt 1 bis 4 besteht aus drei Seitenwänden
5, 6 und 7, wodurch sich ein im wesentlichen dreieckiger
Querschnitt des Sammelkanals ergibt.In the embodiment shown in Fig. 1

Kathete bildende Seitenwand 6 im Deckenbereich der Küche,
d.h. waagerecht verläuft, während die anschließende äußere
Seitenwand 5 parallel zur Wand der Küche, d.h. senkrecht
ausgerichtet ist, und die die Hypotenuse des dreieckigen
Querschnittes bildende Seitenwand 7 schräg verläuft, d.h.
dem Kücheninnenraum zugewandt ist.The arrangement is such that the one
Der aus den vier Kanalabschnitten 1 bis 4 gebildete Sammelkanal ist über einen Stutzen 8 mit einer Saugluftquelle (nicht dargestellt) verbunden, wie dies in Fig. 2 mit einem Pfeil 9 angedeutet ist. The collecting channel formed from the four channel sections 1 to 4 is via a nozzle 8 with a suction air source (not shown) connected, as shown in Fig. 2 with a Arrow 9 is indicated.
Die dem Kücheninnenraum zugewandte Seitenwand 7 jedes
Kanalabschnittes 1 bis 4 ist über die gesamte Länge des
jeweiligen Kanalabschnittes mit einer Kanalöffnung 10 ausgestattet,
die sich im wesentlichen parallel zur Längserstreckung
des jeweiligen Kanalabschnittes erstreckt und
im Bereich ihrer Ränder jeweils mit einer Verstärkung 11
ausgestattet ist. Im vorliegenden Fall werden die Verstärkungen

Wie aus Fig. 1 hervorgeht, wird die Kanalöffnung 10 jeweils
durch verschiedene Einsätze abgedeckt. Im vorliegenden Ausführungsbeispiel
besteht ein Teil dieser Einsätze aus
sogenannten Verschließblenden 13, die die Kanalöffnung 10
in denjenigen Bereichen abdecken, in denen kein Absaugluftstrom
erwünscht ist. Zwischen den Verschließblenden 13 sind
sogenannte Abscheider 14 eingesetzt, über die in der Abluft
enthaltene Partikel oder Tröpfchen abgeschieden und einer
Sammelrinne (nicht dargestellt) oder dergleichen zugefügt
werden können. Diese Abscheider 14 können in
verschiedenster Weise ausgestaltet sein. Ein derartiger
Abscheider ist beispielsweise in der deutschen Patentschrift
P 27 20 201 beschrieben.As can be seen from Fig. 1, the channel opening 10 each

Wie erwähnt, haben Versuche in überraschender Weise
gezeigt, daß die Abkantungen 12 derart gestaltet werden
können, daß auch über große Längen eine präzise
ausgerichtete und mit einfachen Mitteln abdichtbare Auflage
für die Einsätze ausgebildet werden kann. As mentioned, attempts have surprisingly
shown that the
