Description

Gebäudelüffungsvorrichfung zum Einbau in eine Wanddurchbruchsöffnung Building ventilation device for installation in a wall opening
Die Erfindung betriff† eine Gebäudelüffungsvorrichfung zum Einbau in eine Wanddurchbruchsöffnung mit den Merkmalen des Oberbegriffs des AnspruchsThe invention relates to a building ventilation device for installation in a wall opening with the features of the preamble of the claim
1. 1.
Eine solche Gebäudelüffungsvorrichfung dien† z. B. der Entlüftung eines fenster losen Raums wie eines WCs. Sie umfass† zumindest ein Wandeinbaugehäuse, in das eine elektromotorisch angefriebene Venfilafionseinheif einsefzbar ist. Das Wandeinbaugehäuse besteh† im Wesentlichen aus einem Lüftungskanal, der sich durch die Wanddurchbruchsöffnung hindurch bis zur Gebäudeaußenseife erstreck† und der an einem Ende einen Trägerrahmen zur Befestigung auf einer Wandinnenfläche einer Gebäudewand aufweis†. Such a building ventilation device † z. B. the ventilation of a windowless room such as a toilet. It includes † at least one wall installation housing, into which a ventilafion unit rubbed by an electric motor can be inserted. The wall installation housing essentially consists † of a ventilation duct that extends through the opening in the wall to the outside of the building † and that has a support frame at one end for attachment to an inner wall surface of a building wall †.
In feuchten Klimazonen ergib† sich die zusätzliche Anforderung, dass anfallen des Kondenswasser zur Gebäudeaußenseife hin abgeführf werden muss. Dazu kann ein Wandeinbaugehäuse vorgesehen sein, dessen Lüffungskanal mit sei ner Mittelachse nicht genau normal zur Anlagefläche an der Rückseite des Trä gerrahmens ausgerichfef, sondern in einem Winkel dazu geneigt angesfellf ist, insbesondere von bis zu 5°, was zur Ableitung von Kondenswasser ausreichend ist. Andererseits ist eine Wanddurchbruchsöffnung mit Gefälle im Allgemeinen schwieriger herzusfellen als eine mit senkrechter Ausrichtung. Bei einer Kernboh- rung beispielsweise muss das Bohrgerät schräg zur Wandoberfläche ausgerich- fef werden. Hierbei einen kleinen Winkel exakt zu treffen ist schwierig, so dass Abweichungen auffrefen können. Eine nachträgliche Anpassung der Neigung ist aber bei einem einteiligen Wandeinbaugehäuse nicht möglich. Wegen der Schwierigkeiten wird bevorzug† immer dann auf jede Schrägstellung verzichte†, wenn sie nicht wirklich notwendig ist. Somit wären je nach Anforderung am Ein- bauor† unterschiedlich ausgebildete Wandeinbaugehäuse - nämlich solche mi† und ohne Neigung des Lüftungskanals in Bezug auf den Trägerrahmen - not wendig. In humid climates, there is an additional requirement that the condensation water must be drained to the outside of the building. For this purpose, a built-in wall housing can be provided, the ventilation duct with its central axis not being exactly normal to the contact surface on the back of the carrier frame, but inclined at an angle to it, in particular of up to 5 °, which is sufficient for draining condensation water. On the other hand, a wall opening with a slope is generally more difficult to make than one with a vertical orientation. In the case of a core drilling For example, the drill must be aligned at an angle to the wall surface. It is difficult to hit a small angle exactly, so that deviations can arise. Subsequent adjustment of the inclination is not possible with a one-piece wall installation housing. Because of the difficulties, it is preferred † to avoid any inclination † if it is not really necessary. Thus, depending on the requirements on the installation †, differently designed wall installation housings - namely those with a † and without inclination of the ventilation duct in relation to the support frame - would be necessary.
Die Aufgabe der vorliegenden Erfindung besteh† somit darin, ein Wandeinbau gehäuse so zu verbessern, dass es in allen Klimazonen universell einsetzbar ist und dass der Einbau erleichtert wird. The object of the present invention is therefore to improve a wall installation housing in such a way that it can be used universally in all climatic zones and that installation is made easier.
Eine Lösung dafür gib† die Erfindung mi† der Gebäudelüftungsvorrichtung mi† den Merkmalen des Anspruchs 1 an. A solution for this is given by the invention with the building ventilation device with the features of claim 1.
Diese Lösung zeichne† sich insbesondere dadurch aus, dass Trägerrahmen und Lüftungskanal an zwei Gelenkpunkten gelenkig miteinander verbunden sind. Daher ist der Winkel zwischen dem auf der Wand zu montierenden Trägerrah men und dem sich daran anschließenden Lüftungskanal in einem ausreichen den Winkelbereich variabel, so dass sowohl eine Neigung von beispielsweise ±5° wie auch eine exakt senkrechte Stellung einstellbar ist. Im zuletz† genannten Fall ist die Mittelachse des Lüftungskanals parallel zur Flächennormalen einer Anla gefläche des Trägerrahmens ausgerichte† oder fäll† damit zusammen. This solution is characterized in particular by the fact that the support frame and ventilation duct are articulated to one another at two points of articulation. Therefore, the angle between the support frame to be mounted on the wall and the adjoining ventilation duct is variable in a sufficient angular range, so that both an inclination of, for example, ± 5 ° and an exactly vertical position can be set. In the last † case mentioned, the central axis of the ventilation duct is aligned † or coincides † with the surface normal of a contact surface of the support frame.
Die Gelenkpunkte sind am Trägerrahmen an einem Anschlusskragen angeord- ne†, welcher rückwärtig von dem Trägerrahmen absteh† und in Richtung der Wanddurchbruchsöffnung rag†. Am Lüftungskanal sind die Gelenkpunkte im Mündungsbereich vorgesehen. Außerdem ist der Querschnitt des Lüftungska nals zumindest an zwei sich gegenüberliegenden Seiten gegenüber dem An schlusskragen reduzier†, so dass in dem genannten Winkelbereich eine Beweg lichkeit der Teile zueinander gegeben ist. Der Vorteil liegt darin, dass die Neigung direkt auf der Baustelle einstellbar ist. Besteh† beispielsweise eine geringfügige Winkelabweichung im Gefälle der Wanddurchbruchsöffnung vom Sollmaß, wird diese direkt beim Einbau ausge glichen. Das Wandeinbaugehäuse kann entweder komplett, mi† dem Lüftungs kanal voran in die Wandöffnung eingeschoben werden, oder es wird zunächst zerleg†, so dass der Lüftungskanal zunächst allein eingesetzt, ausgerichte† und fixier† wird, bevor der Trägerrahmen an den Gelenkpunkten angekoppel† wird. The pivot points are arranged on the support frame on a connection collar †, which protrudes from the support frame at the rear † and protrudes in the direction of the opening in the wall †. The articulation points are provided in the mouth area of the ventilation duct. In addition, the cross-section of the ventilation duct is reduced at least on two opposite sides in relation to the connection collar, so that the parts can be moved relative to one another in the aforementioned angular range. The advantage is that the inclination can be adjusted directly on the construction site. If, for example, there is a slight angular deviation in the slope of the wall opening from the nominal dimension, this is compensated for directly during installation. The in-wall housing can either be pushed into the wall opening completely, with the ventilation duct first, or it is first dismantled † so that the ventilation duct is initially inserted, aligned † and fixed † before the support frame is coupled † to the hinge points.
Für den Einsatz des Wandeinbaugehäuses bei der Gebäudeentlüftung sollte der von einer Ventilationseinhei† erzeugte Luftstrom zu einem überwiegenden Teil direkt in den Lüftungskanal geleite† werden. Totzonen oder gar Öffnungen im Übergangsbereich sollten vermieden werden. Daher sieh† die Erfindung ei nen Anschlusskragen vor, der den Mündungsbereich des Lüftungskanals umgib†, und außerdem sind im Bereich des Anschlusskragens die Gelenkpunkte angeordne†. Durch die geeignete Abstimmung der Geometrien von Anschluss kragen und Lüftungskanal wird erreich†, dass der Lüftungskanal in seiner geneig ten Stellung mi† seiner Unterseite auf einer Kante an einem unteren horizontalen Abschnitt des Anschlusskragens auflieg† und außerdem mi† seiner oberen hori zontalen Kante von innen an einem oberen horizontalen Abschnitt des An schlusskragens drück†. Oben und unten müssen also nur sehr kleine Spalte zwi schen der Außenseite des Lüftungskanals und der Innenseite des Anschlusskra gens vorgesehen werden, wodurch zwar eine geringe Schrägstellung ermög lich† wird, aber keine offenen Querschnitte entstehen. Seitlich sind gar keine Spalte notwendig. For the use of the in-wall housing for building ventilation, the air flow generated by a ventilation unit † should for the most part be directed directly into the ventilation duct †. Dead zones or even openings in the transition area should be avoided. The invention therefore provides a connection collar which surrounds the opening area of the ventilation duct, and the hinge points are also arranged in the area of the connection collar. Suitable coordination of the geometries of the connection collar and ventilation duct ensures that the ventilation duct in its inclined position rests with its underside on an edge on a lower horizontal section of the connection collar † and also with its upper horizontal edge from the inside press † on an upper horizontal section of the connection collar. So only very small gaps need to be provided at the top and bottom between the outside of the ventilation duct and the inside of the connecting collar, which allows a slight inclination †, but does not create any open cross-sections. No gaps at all are necessary on the side.
Möglich ist auch, eine zusätzliche Abschlussblende vorzusehen, die am Ende des Lüftungskanals aufgesetzt wird. Eine solche Abschlussblende kann auch Teil einer Ventilationseinhei† sein, die in den Lüftungskanal eingeschoben wird. It is also possible to provide an additional cover panel that is placed at the end of the ventilation duct. Such a cover panel can also be part of a ventilation unit † that is pushed into the ventilation duct.
Bevorzug† sind Lüftungskanal und Abschlussblende zumindest in dem Bereich, in dem sie überlappen, im Querschnitt gesehen in einer rechteckigen Konfigura tion ausgebilde†, das hei߆ es gib† zwei sich gegenüberliegende parallele Sei ten, wobei die Ecken aus strömungstechnischen Gründen gerundet sind. Möglich sind aber auch andere Querschnittsformen, wie insbesondere eine Kreisform, so dass runde Lüffungskanäle für den Wanddurchbruch verwendet werden können. Preferably † the ventilation duct and cover panel, at least in the area in which they overlap, are designed in a rectangular configuration when viewed in cross-section †, i.e. † there are † two opposite parallel sides, with the corners being rounded for flow reasons. However, other cross-sectional shapes are also possible, in particular a circular shape, so that round ventilation ducts can be used for the wall opening.
Weitere vorteilhafte Ausgestaltungen der Erfindung werden nachfolgend mit Bezug auf das in den Zeichnungen dargesfellfe Ausführungsbeispiel erläutert. Die Figuren zeigen im Einzelnen: Further advantageous embodiments of the invention are explained below with reference to the exemplary embodiment shown in the drawings. The figures show in detail:

Figur 1 zeig† eine Gebäudelüftungsvorrichtung 100 gemäß einer bevorzugten Ausführungsform. Diese umfass† neben einem Trägerrahmen 10 und einem Lüf tungskanal 20 auch eine speziell angepasste Ventilationseinhei† 30, welche in den Lüftungskanal 20 eingeschoben werden kann. Nach Abschluss der Mon tage wird ein Lüftungsgitter 40 auf den Trägerrahmen 10 aufgesetzt. Figure 1 shows a building ventilation device 100 according to a preferred embodiment. In addition to a support frame 10 and a ventilation duct 20, this also includes a specially adapted ventilation unit 30, which can be pushed into the ventilation duct 20. After completion of the Mon days, a ventilation grille 40 is placed on the support frame 10.
Der Trägerrahmen 10 ist an seiner Rückseite mi† einem Anschlusskragen 12 ver sehen, der senkrecht von einer rückwärtigen Anlagefläche 1 1 absteh† und Ge lenkpunkte zur Verbindung mi† dem Lüftungskanal 20 besitz†. Die Ventilations einhei† 30 ist so angepass†, dass sie in den lichten Querschnitt des Lüftungskanals 20 eingeschoben werden kann. Sie ist mi† einer endseitig ausgebildeten Ab schlussblende 31 versehen, sodass vermieden wird, dass die Ventilationseinhei† 30 zu weit in den Lüftungskanal 20 hineinrutsch†. Figur 2 zeig† den Trägerrahmen 10 allein in perspektivischer Ansicht. Dieser um fass† in der dargesfellfen Ausführungsform eine rechteckige, umfänglich ge schlossene Basisplatte 17, deren Rückseite die Anlagefläche 1 1 bilde†. Senk recht zu der Basisplatte 17 ist ein Anschlusskragen 12 ausgebilde†, der eine Lüf tungsöffnung 13 umgib† und der zwei horizontale Abschnitte 15 und zwei verti kale Abschnitte 14 umfass†. Diese Konfiguration ist grundsätzlich zwar aus zwei Paaren von parallelen Wandabschnitten 14, 15 gebildet, welche die Lüftungs öffnung 13 umgeben, also rechteckig. Die jeweiligen Eckenbereiche sind aber großzügig gerundet ausgebilde†, um einen strömungsgünstigen Querschnitt zu erhalten. The support frame 10 is seen on its rear side with a connection collar 12 which protrudes perpendicularly from a rear contact surface 11 and has articulation points for connection to the ventilation duct 20. The ventilation unit † 30 is adapted † so that it can be pushed into the clear cross section of the ventilation duct 20. It is provided with a closure panel 31 formed at the end, so that the ventilation unit † 30 is prevented from slipping too far into the ventilation duct 20 †. Figure 2 shows the support frame 10 alone in a perspective view. This around fass † in the Dargesfellfen embodiment a rectangular, circumferentially closed base plate 17, the back of which forms the contact surface 11 †. A connection collar 12 is formed perpendicularly to the base plate 17 †, which surrounds a ventilation opening 13 † and which includes two horizontal sections 15 and two vertical sections 14 †. This configuration is basically formed from two pairs of parallel wall sections 14, 15 which surround the ventilation opening 13, that is to say rectangular. However, the respective corner areas are generously rounded † in order to obtain a flow-favorable cross-section.
An den vertikalen Abschnitten 14 des Anschlusskragens 12 ist jeweils ein Gelenk punk† 16 ausgebilde†, der bei der dargestellten bevorzugten Ausführungsform exakt auf halber Höhe der vertikalen Abschnitte 14 angeordne† ist. Der An schlusskragen 12 ist damit bevorzug† spiegelsymmetrisch in Bezug auf die zwi schen den Gelenkpunkten 16 gebildete Achse. Somit kann die Neigung des an den Gelenkpunkten 16 anzusetzenden Lüftungskanals in beide Richtungen ein gestellt werden, und es muss bei der Montage des Trägerrahmens 10 auf der Wand nicht auf dessen korrekte Einbaulage geachtet werden. On each of the vertical sections 14 of the connection collar 12 a joint point 16 is formed which, in the preferred embodiment shown, is arranged exactly halfway up the vertical sections 14. The connection collar 12 is thus preferably mirror-symmetrical with respect to the axis formed between the hinge points 16. Thus, the inclination of the ventilation duct to be attached to the hinge points 16 can be set in both directions, and it is not necessary to pay attention to its correct installation position when mounting the support frame 10 on the wall.
Die Basisplatte 17 ist an ihrer Außenkante mi† einem umlaufenden Kragen 18 versehen, auf welchen das in Figur 1 dargestellte Lüftungsgitter 40 aufgesetzt werden kann. The base plate 17 is provided on its outer edge with a circumferential collar 18 on which the ventilation grille 40 shown in FIG. 1 can be placed.
In Figur 3 ist die Grundkonfiguration des Wandeinbaugehäuses der erfindungs gemäßen Gebäudelüftungsvorrichtung 100 dargestell†, wobei der zuvor be schriebene Trägerrahmen 10 gelenkig mi† dem Lüftungskanal 20 gekoppelt ist. Die Kopplung erfolg† dadurch, dass der Lüftungskanal 20 in seinem Mündungs bereich an gegenüberliegenden Seiten jeweils eine Ausnehmung 21 besitz†, in welche je ein Gelenkzapfen 16 eingreif†. In Figure 3, the basic configuration of the built-in wall housing of the fiction, contemporary building ventilation device 100 is dargestell †, wherein the previously described support frame 10 is articulated with the ventilation duct 20 is coupled. The coupling takes place † in that the ventilation duct 20 in its mouth area on opposite sides each has a recess 21 †, in each of which a pivot pin 16 engages †.
Wie im rechten Teil von Figur 1 erkennbar, sind Ausnehmungen 21 an beiden Seiten des Lüftungskanals 20 ausgebilde†, sodass beim Einbau des Lüftungska nals 20 in die Wanddurchbruchsöffnung nicht darauf geachtet werden brauch†, welche der beiden Enden zur Gebäudeinnenseite angeordnet ist. Au ßerdem ist es grundsätzlich möglich, einen gleichartigen Trägerrahmen 10 auch am anderen Ende, also zur Gebäudeaußenseite hin, vorzusehen. As can be seen in the right-hand part of FIG. 1, recesses 21 are formed on both sides of the ventilation duct 20, so that no attention is paid to this when installing the ventilation duct 20 in the opening in the wall need †, which of the two ends is facing the inside of the building. In addition, it is basically possible to provide a support frame 10 of the same type at the other end, that is to say towards the outside of the building.
In Figur 3 ist die Schrägstellung des Lüftungskanals 20 in Bezug auf die Anlage fläche 1 1 insbesondere bei den horizontalen Abschnitten 15 des Anschlusskra gens 12 erkennbar. An dem unteren horizontalen Abschnitt 15 rag† eine Außen kante 22 des Lüftungskanals 20 etwas über die Basisplatte 17 hinaus, wohinge gen im oberen Bereich die Außenkante 22 gegenüber der Basisplatte 17 etwas zurückspring†, sodass dort ein Teil des Anschlusskragens 12 sichtbar is†. Allerdings lieg† oben die Außenkante 22 direkt an den horizontalen oberen Abschnitt 15 des Anschlusskragens 12 an. In Figure 3, the inclination of the ventilation duct 20 in relation to the contact surface 1 1, in particular in the horizontal sections 15 of the connection collar 12 can be seen. On the lower horizontal section 15, an outer edge 22 of the ventilation duct 20 protrudes slightly beyond the base plate 17, whereas in the upper area the outer edge 22 springs back slightly from the base plate 17, so that part of the connecting collar 12 is visible there. However, at the top, the outer edge 22 lies directly against the horizontal upper section 15 of the connection collar 12.
Figur 4 zeig† einen sich an die Situation aus Figur 3 anschließenden Monfage- schri††. Flierbei ist eine Venfilafionseinheif 30 in den Lüffungskanal 20 eingescho ben worden, und zwar so weif, bis die Venfilafionseinheif 30 mi† ihrer Abschluss blende 31 an der Außenkante 22 des Lüftungskanals 20 anlieg†. Der Außenum fang der Abschlussblende 31 entsprich† der Kontur des Lüftungskanals 20 im Be reich seiner Außenkante 22. Die Blende 31 steh† also nicht über die Außenkante 22 hervor, sodass sie auch die Einstellung der Neigung des Lüftungskanals 20 gegenüber dem Trägerrahmen 10 nicht behindert. FIG. 4 shows a mounting document following the situation from FIG. 3. At the same time, a ventilation unit 30 has been pushed into the ventilation duct 20 until the ventilation unit 30 with its end panel 31 lies against the outer edge 22 of the ventilation duct 20. The outer circumference of the cover plate 31 corresponds to the contour of the ventilation duct 20 in the area of its outer edge 22. The cover 31 does not protrude beyond the outer edge 22, so that it does not hinder the setting of the inclination of the ventilation duct 20 relative to the support frame 10.
Figur 5 zeig† die fertig montierte Belüftungsvorrichtung 100. Der Lüftungskanal 20 ist in einem Winkel a von etwa 5° in Bezug auf die Flächennormale des Träger rahmens 10 an seiner Anlagefläche 1 1 ausgerichte†. Die Ventilationseinhei† 30 ist in den Lüftungskanal 20 eingeschoben, und das Lüftungsgitter 40 ist so auf den Trägerrahmen 10 aufgesetzt, dass sie den Kragen 18 des Trägerrahmens 10 vollständig umschlie߆. Figure 5 shows † the fully assembled ventilation device 100. The ventilation channel 20 is aligned at an angle α of about 5 ° with respect to the surface normal of the support frame 10 on its contact surface 11 †. The ventilation unit † 30 is pushed into the ventilation duct 20, and the ventilation grille 40 is placed on the support frame 10 in such a way that it completely encloses the collar 18 of the support frame 10.
Wesentlich für die gute Einstellbarkei† der Neigung ist der in Figur 5 unten links markierte Bereich am Anschlusskragen unten sowie des entsprechenden Ge genstücks oben am Anschlusskragen 12. Der untere Bereich ist zur Verdeutli chung in Figur 6 in einem vergrößerten Detail dargestell†. Dort ist zum einen er kennbar, wie die Unterseite des Lüftungskanals 20 auf dem unteren horizontalen Abschnitt des Anschlusskragens 12 auflieg†. Weiterhin ist erkennbar, dass hinter der Anschlussblende 31, der Ventilationseinhei† 30 noch ein Dichtungsring 32 vorgesehen ist. Die Anschlussblende 31 lieg† somit mit dem Dichtungsring 32 an ihrer Rückseite an der Außenkante 22 des Lüftungskanals 20 an. An der Rück seite des Lüffungsgiffers 40 ist eine umlaufende Dichtung vorgesehen, die an dem Kragen 18 (vgl. Fig. 1 ) anlieg† Essential for the good adjustability of the inclination is the area marked at the bottom left in FIG. 5 on the connection collar at the bottom and the corresponding counterpart at the top of the connection collar 12. The lower area is shown in an enlarged detail in FIG. 6 for clarity. There he can be seen on the one hand, as the underside of the ventilation duct 20 on the lower horizontal Section of the connection collar 12 on top †. It can also be seen that a sealing ring 32 is also provided behind the connection panel 31, the ventilation unit † 30. The connecting panel 31 is therefore in contact with the sealing ring 32 on its rear side against the outer edge 22 of the ventilation duct 20. A circumferential seal is provided on the back of the ventilation gripper 40, which rests on the collar 18 (see FIG. 1) †
Bei der bevorzugten Ausführungsform ist der axiale Abstand der Gelenkpunkte 21 am Lüftungskanal 20 zur Außenkante 22 kleiner ist als der axiale Abstand der Gelenkpunkte 15 zur Vorderseite der Basisplatte 17 des Trägerrahmens 10. Dadurch rag† der geneigt ausgerichtete Lüftungskanal 20 nur mi† seiner unteren Kante ein wenig nach außen, so dass er nicht gegen das auf den Trägerrahmen 10 aufgesetzte Lüftungsgitter 40 stößt. In the preferred embodiment, the axial distance between the hinge points 21 on the ventilation duct 20 and the outer edge 22 is smaller than the axial distance between the hinge points 15 and the front of the base plate 17 of the support frame 10. As a result, the inclined ventilation duct 20 protrudes only with its lower edge little to the outside, so that it does not hit the ventilation grille 40 placed on the support frame 10.
