Description

Die Erfindung bezieht sich auf ein Bauteil aus Metall für eine Einrichtung in einem Raum mit Dampf, insbesondere fetthaltigen Dampf, erzeugenden Geräten, über denen eine den Dampf und Luft enthaltende Fluidströmung entsteht.The invention relates to a component made of metal for a device in a room with steam, in particular fatty steam, generating devices over which a fluid flow containing the steam and air is created.

Bei bekannten Bauteilen in Form von Sammelrinnen und Tragköpfen (DE 29 49 235 C2), wie sie für abgehängte Lüftungsdecken in Räumen mit Wasserdampf, fetten Wrasen, Schwebeteilchen oder sonstigen Verunreinigungen in der Raumluft verwendet werden, ist der Boden nach unten gewölbt und der Fluidströmung zugekehrt. Das Fluid strömt hierbei am Boden des Bauteils unter Verdrängung der an dem Boden angrenzenden Luftschicht vorbei. Dabei bildet sich am Boden des Bauteils Kondensat, das vom Boden abtropfen und in den Raum fallen kann.In the case of known components in the form of collecting channels and support heads (DE 29 49 235 C2), such as are used for suspended ventilation ceilings in rooms with water vapor, greasy vapors, suspended particles or other contaminants in the ambient air, the floor is curved downwards and the fluid flow is turned . The fluid flows past the bottom of the component, displacing the air layer adjacent to the bottom. Condensate forms on the bottom of the component, which can drip off the floor and fall into the room.

Der Erfindung liegt die Aufgabe zugrunde, ein Bauteil der eingangs genannten Art anzugeben, das eine solche Kondensatbildung verhindert.The invention has for its object to provide a component of the type mentioned that prevents such condensation.

Gemäß der Erfindung ist diese Aufgabe dadurch gelöst, daß das Bauteil eine gegen die Fluidströmung offene Kammer aufweist, die so geformt ist, daß sie eine Verdrängung der am Boden der Kammer auf seiten der Fluidströmung angrenzenden Luftschicht durch die Fluidströmung weitgehend verhindert.According to the invention, this object is achieved in that the component has an open chamber against the fluid flow, which is shaped so that it largely prevents displacement of the air layer adjacent to the bottom of the chamber on the fluid flow side by the fluid flow.

Bei dieser Lösung dringt das Fluid praktisch nicht in die Kammer ein, so daß die Innenflächen der Kammer weitgehend nicht mit dem Fluid in Berührung kommen und der in dem Fluid enthaltene Dampf nicht kondensieren kann.With this solution, the fluid practically does not penetrate into the chamber, so that the inner surfaces of the chamber largely do not come into contact with the fluid and the vapor contained in the fluid cannot condense.

Bei dem Bauteil kann es sich um verschiedenste Arten von Bauteilen handeln. Vorzugsweise ist dafür gesorgt, daß es die Form eines Tragkopfes mit radial abstehenden Tragarmen für eine Lüftungseinrichtung mit Kondensatbildung aufweist, wobei die Lüftungseinrichtung wenigstens eine der Kondensatbildung dienende, nach oben gewölbte Kassette aufweist, deren Ränder jeweils in eine Sammelrinne ragen und sich auf den Tragarmen abstützen, und daß der Tragkopf an seiner Unterseite die Kammer aufweist.The component can be a wide variety of types of components. It is preferably ensured that it has the shape of a support head with radially projecting support arms for a ventilation device with condensate formation, the ventilation device having at least one condensation-forming, upwardly curved cassette, the edges of which each protrude into a collecting channel and are supported on the support arms , and that the support head has the chamber on its underside.

Das Bauteil kann auch die Form der erwähnten Sammelrinne aufweisen, die an ihrer Unterseite wenigstens eine derartige Kammer aufweist.The component can also have the shape of the collecting channel mentioned, which has at least one such chamber on its underside.

Besonders günstige Verhältnisse ergeben sich, wenn die Kammer einen rechtwinkligen oder trapezförmigen Querschnitt aufweist und die Querschnittsebene mit der Fluidströmungsrichtung zusammenfällt.Particularly favorable conditions result when the chamber has a rectangular or trapezoidal cross-section and the cross-sectional plane coincides with the direction of fluid flow.

Die Großküche nach Fig. 1 enthält eine von der Raumdecke abgehängte Lüftungseinrichtung in Form einer Lüftungsdecke 1. Die Lüftungsdecke 1 enthält nach oben gewölbte doppelwandige Kassetten 2, die nebeneinander angeordnet sind. Ein Abluftkanal 3 oberhalb der Lüftungsdecke saugt durch Löcher 4 (Fig. 2 und 4) mit nach innen umgebogenen Rändern in den Innenwänden 5 und Außenwänden 6 der Kassetten 2 Luft aus dem Küchenraum an. Dabei kann in der Luft enthaltener Dampf an den metallischen Wänden 5 und 6 kondensieren und das Kondensat in nach oben offene Sammelrinnen 7a abfließen, in die sich die Ränder der Kassetten 2 erstrecken (vgl. insbesondere Fig. 2 und 4). Die Kassetten 2 stützten sich mit ihren Eckbereichen, siehe insbesondere Fig. 5, auf horizontalen Tragarmen 8 kreuzförmiger Tragköpfe 9 ab, die über Stangen 10 (siehe Fig. 2, 4 und 5) an der Küchendecke aufgehängt sind. Die Tragarme 8 und Tragköpfe 9 haben nach oben abgewinkelte Seitenwände 8a, zwischen denen das Kondensat ebenfalls in die Sammelrinne 7a abfließen kann.The commercial kitchen according to FIG. 1 contains a ventilation device suspended from the ceiling in the form of a ventilation ceiling 1. The ventilation ceiling 1 contains double-walled cassettes 2 which are curved upwards and are arranged next to one another. An exhaust air duct 3 above the ventilation ceiling sucks in air from the kitchen space through holes 4 (FIGS. 2 and 4) with edges bent inwards in the inner walls 5 and outer walls 6 of the cassettes 2. Steam contained in the air can condense on the metallic walls 5 and 6 and the condensate can flow into collecting channels 7a which are open at the top and into which the edges of the cassettes 2 extend (cf. in particular FIGS. 2 and 4). The cassettes 2 are supported with their corner areas, see in particular FIG. 5, on horizontal support arms 8 of cross-shaped support heads 9 which are suspended from the kitchen ceiling via rods 10 (see FIGS. 2, 4 and 5). The support arms 8 and support heads 9 have upwardly angled side walls 8a, between which the condensate can also flow into the collecting channel 7a.

Die Endabschnitte der Längsränder jeder Sammelrinne 7a sind jeweils mit einer in Richtung zum jeweils gegenüberliegenden Längsrand der Sammelrinne 7a ragenden Rastnase 11 versehen. Die Rastnasen 11 sind durch Einschnitte in den Längsrändern und Ausbauchung nach innen ausgebildet, so daß sie durch Hochschieben der Sammelrinne 7a über die Seitenwände 8a der Tragarme 8 hinweggleiten und jeweils über den oberen Rand der Seitenwände 8a einschnappen können. Die Sammelrinnen 7a haben ferner an jedem Ende eine Stirnwand 12.The end portions of the longitudinal edges of each collecting channel 7a are each provided with a locking lug 11 projecting in the direction of the respectively opposite longitudinal edge of the collecting channel 7a. The locking lugs 11 are formed by incisions in the longitudinal edges and bulge inwards, so that they slide over the side walls 8a of the support arms 8 by pushing up the collecting channel 7a and can each snap over the upper edge of the side walls 8a. The collecting troughs 7a also have an end wall 12 at each end.

Wie Fig. 6 deutlicher zeigt, hat jeder Tragkopf 9 eine gegen die aufwärts gerichtete Fluidströmung aus Dampf, insbesondere fetthaltigen Dampf, und Luft offene Kammer 13a. Bei dieser Kammer 13a, deren Querschnitt rechtwinklig ist, wobei die Querschnittsebene mit der Fluidströmungsrichtung zusammenfällt, ist das Verhältnis von Tiefe oder Höhe zur Grundfläche so gewählt, daß sie eine Verdrängung der auf seiten der Fluidströmung am Boden 14 der Kammer 13a befindlichen Luftschicht, hier praktisch die gesamte in der Kammer 13a enthaltene Luft, weitgehend verhindert. Das Fluid strömt daher praktisch nicht in die Kammer 13a hinein, sondern wird unterhalb der Kammer seitlich umgelenkt, so daß es auch praktisch nicht mit der Kammer 13a in Berührung kommt und der im Fluid enthaltene Dampf weder außen noch innen an der Kammer 13a kondensieren kann. Auf diese Weise wird ein Herabtropfen von Kondensat an den Tragköpfen 9 in den Küchenraum vermieden.As FIG. 6 shows more clearly, each support head 9 has a chamber 13a which is open to the upward fluid flow of steam, in particular fatty steam, and air. In this chamber 13a, the cross section of which is rectangular, the cross-sectional plane coinciding with the direction of fluid flow, the ratio of depth or height to the base area is chosen so that it largely displaces the air layer located on the side of the fluid flow at the bottom 14 of the chamber 13a, here practically all of the air contained in the chamber 13a prevented. The fluid therefore practically does not flow into the chamber 13a, but is deflected laterally below the chamber, so that it practically does not come into contact with the chamber 13a and the vapor contained in the fluid cannot condense on the outside or inside of the chamber 13a. In this way, dripping of condensate on the support heads 9 into the kitchen is avoided.

Fig. 7 stellt einen abgewandelten Tragkopf 9a dar, dessen Querschnitt in einer mit der Fluidströmungsrichtung zusammenfallenden Querschnittsebene trapezförmig ist, wobei sich der Abstand der Seitenwände der Kammer 13b zu ihrem Boden 14 hin verringert. Im übrigen ist sie ebenso bemessen, wie die Kammer 13a nach Fig. 6. Bei dieser Abwandlung ist in noch höherem Maße sichergestellt, daß das aufwärts strömende Fluid auch nicht mit den Außenflächen der Seitenwände der Kammer 13b in Berührung kommt.FIG. 7 shows a modified support head 9a, the cross section of which is trapezoidal in a cross-sectional plane that coincides with the fluid flow direction, the distance between the side walls of the chamber 13b and its bottom 14 decreasing. Otherwise, it is dimensioned in the same way as the chamber 13a according to FIG. 6. With this modification, it is ensured to an even greater extent that the upward flowing fluid does not come into contact with the outer surfaces of the side walls of the chamber 13b.

Wie die Fig. 8 und 9 zeigen, ist auch die Sammelrinne 7a an ihrer Unterseite mit einer der Kammer 13a entsprechenden Kammer 13c versehen, deren Boden 15 gleichzeitig den Boden der Sammelrinne 7a bildet.As FIGS. 8 and 9 show, the collecting trough 7a is also provided on its underside with a chamber 13c corresponding to the chamber 13a, the bottom 15 of which simultaneously forms the bottom of the collecting trough 7a.

Die Sammelrinne 7b nach den Fig. 10 und 11 ist auf der Unterseite mit mehreren in Längsrichtung der Sammelrinne 7b hintereinanderliegenden Kammern 13d mit trapezförmigem Querschnitt entsprechend der Kammer 13b nach Fig. 7 versehen, wobei auch hier die Böden 15 der Kammern 13d gleichzeitig den Boden der Sammelrinne 7b bilden.The collecting trough 7b according to FIGS. 10 and 11 is provided on the underside with a plurality of chambers 13d, one behind the other in the longitudinal direction of the collecting trough 7b, with a trapezoidal cross-section corresponding to the chamber 13b according to FIG. 7, the bottoms 15 of the chambers 13d also being the bottom of the chambers Form collecting channel 7b.

Die Sammelrinne 7c nach den Fig. 12 und 13 unterscheidet sich von der nach den Fig. 8 und 9 lediglich darin, daß die Kammer 13e im Querschnitt trapezförmig und getrennt von der Sammelrinne 7c ausgebildet ist, wobei der Boden 15 der Kammer 13e mit dem Boden 16 der Sammelrinne 7c, z.B. durch Punktschweißung oder Kleben, verbunden ist. Die getrennte Ausbildung der Kammer 13e hat den Vorteil, daß sie auch aus einem anderen Material als die Sammelrinne 7c, die üblicherweise aus Metall besteht, hergestellt werden kann, wobei das Material der Kammer 13e so gewählt werden kann, daß es die Kondensatbildung schon von sich aus erschwert.The collecting trough 7c according to FIGS. 12 and 13 differs from that according to FIGS. 8 and 9 only in that the chamber 13e is trapezoidal in cross-section and separate from the collecting trough 7c, the bottom 15 of the chamber 13e with the bottom 16 of the collecting channel 7c, for example is connected by spot welding or gluing. The separate formation of the chamber 13e has the advantage that it can also be made of a different material than the collecting channel 7c, which usually consists of metal, the material of the chamber 13e can be chosen such that it already condensates out difficult.

Die Erfindung ist nicht auf Bauteile wie Sammelrinnen und Tragköpfe von Lüftungsdecken beschränkt, sondern kann auch bei allen anderen Bauteilen aus Metall angewandt werden, die einer Dampf und Luft enthaltenden Fluidströmung ausgesetzt sind.The invention is not restricted to components such as collecting channels and support heads of ventilation ceilings, but can also be applied to all other metal components which are exposed to a fluid flow containing steam and air.
