Description

Die Erfindung betrifft ein Fenster-Lüftungsgerät, welches in der Lage ist, Luft zwischen einem Außenraum und einem Innenraum auszutauschen und dabei die Luft im Innenraum qualitativ "zu verbessern". Dem Fenster-Lüftungsgerät wird ein nicht mehr als bereichsweiser Einbau in den profilierten Rahmen ermöglicht und es werden Elemente des fest stehenden (unbeweglichen) Rahmens als Hohlkammern in Form von Strömungskanälen für die Luftführung zum Wärme- und/oder Feuchtigkeitstausch verwendet.The invention relates to a window ventilation device, which is able to exchange air between an exterior space and an interior, while the quality of the air in the interior "to improve". The window ventilation device is not more than area-wise installation in the profiled frame allows and there are elements of the fixed (immovable) frame used as hollow chambers in the form of flow channels for the air duct for heat and / or moisture exchange.

Aus der DE-U 20 2011 003463 (Schellenberg ) ist ein dezentrales Lüftungsgerät als integrierter Fensterrahmen bekannt, welches einen Axiallüfter einsetzt. Offen ist die Vorderseite.From the DE-U 20 2011 003463 (Schellenberg ) is a decentralized ventilation unit known as an integrated window frame, which uses an axial fan. Open is the front.

Die EP 1 486 637 offenbart ein Lüftungsgerät für ein Fenster, bei dem an gegenüberliegenden Seiten eines Gehäuses jeweils zwei Öffnungsbereiche vorgesehen sind, um Außenluft nach innen und Innenluft nach außen strömen zu lassen. In einem mittleren Bereich ist ein Wärmetauscher vorgesehen.The EP 1 486 637 discloses a ventilation device for a window, in which two opening areas are provided on opposite sides of a housing, in order to allow outside air to flow inwards and inside air to the outside. In a central region, a heat exchanger is provided.

In der WO 2011/105 969 ist eine Lüftungsvorrichtung mit einem Wärmetauscher bekannt. Über Ventilatoren kann ein Luftstrom von innen nach außen und von außen nach innen zirkulieren.In the WO 2011/105 969 is a ventilation device with a heat exchanger known. Fans can circulate airflow from inside to outside and from outside to inside.

Eine Problemstellung der beanspruchten Erfindung liegt darin, den verdeckten Einbau eines solchen Fenster-Lüftungsgeräts bauseits zu realisieren. Es soll dabei nicht vollständig in den Festrahmen integriert sein, sondern muss bereichsweise (volumenmäßig betrachtet) herausragen. Trotz des Fenster-Lüftungsgeräts im Festrahmen (Blendrahmen) soll die Glasgröße im beweglichen Flügel erhalten bleiben, der Blendrahmen soll also nicht größer werden (sich nach innen ausweiten), um das Lüftungsgerät aufzunehmen, sondern der Glasanteil des Flügels soll gleich groß bleiben. Zusätzlich geschaffene Bauräume, die auf Kosten der Tür- oder Fensterglasgröße des beweglichen Flügels gehen, sind aufgabengemäß zu vermeiden. Unter einer "Bewegung" wird ein Kippen, Schwenken oder Schieben verstanden, auch deren beliebige Kombination.A problem of the claimed invention is to realize the covert installation of such a window ventilation device on site. It is not intended to be fully integrated into the fixed frame, but must protrude in areas (in terms of volume). Despite the window ventilation device in the fixed frame (frame), the glass size in the movable wing is to remain, so the frame should not be larger (expand inward) to accommodate the ventilation unit, but the glass portion of the wing should remain the same size. Additionally created installation spaces, which are at the expense of the door or window glass size of the movable sash, are to be avoided according to the task. A "movement" is understood to mean tilting, swiveling or pushing, or any combination thereof.

Die Lösung findet sich in Anspruch 1 oder Anspruch 15.The solution can be found in claim 1 or claim 15.

Gegenstand der Beanspruchung ist nur das Fenster-Lüftungsgerät und seine Eigenschaften oder Eignungen, in einen feststehenden Rahmen (Blendrahmen) eines Flügels (mit einem Flügelrahmen und einem Glaselement) eingebaut zu werden, ohne dass damit der Rahmen oder das Rahmenprofil als solches oder der Flügel oder das Glaselement mit beansprucht ist. Soweit dieser Profilrahmen in Form von Funktions- und Eignungsangaben genannt ist (als Zweckbestimmung oder Zweckverwirklichung), dient das Hohlprofil zur komplementären Umschreibung der Anpassung, Ausgestaltung und Eignung des Fenster- Lüftungsgeräts als solches (und seines Arbeitsverfahrens).Subject of the claim is only the window ventilation unit and its properties or aptitudes, in a fixed frame (frame) of a wing (with a sash and a glass element) to be installed without affecting the frame or the frame profile as such or the wing or the glass element is claimed with. As far as this profile frame is mentioned in the form of functional and suitability specifications (as a purpose or purpose realization), the hollow profile is used to complement the adaptation, design and suitability of the window ventilation device as such (and its working method).

Vom Wesen her benötigt das beanspruchte Fenster-Lüftungsgerät dabei vier Öffnungen (im allgemeinen Sinne verstanden auch "Auslässe", wobei diese auch einen Einlass umfassen, eben abstrakt im Sinne einer "Strömungsöffnung" als Öffnungsbereich).In essence, the claimed window ventilation device requires four openings (understood in the general sense also "outlets", which also include an inlet, just abstract in the sense of a "flow opening" as the opening area).

Zwei Strömungsöffnungen sind nach außen wirkend (nicht: gerichtet) bereitzustellen, mit Blick auf den Flügel als Trennebene, "außen" im Sinne der wetterabhängigen Seite. Zwei Strömungsöffnungen sind für die Innenseite wirkend zu platzieren ("innen" mit Blick auf den Wohnbereich). Diese vier Strömungs-Öffnungsbereiche, zwei davon sind Auslässe, zwei davon sind Ansaugöffnungen, sind so passend auf das Lüftungsgerät verteilt, dass sie strömungstechnisch günstig liegen, das Fenster-Lüftungsgerät bautechnisch klein gestalten lassen und gleichzeitig Umgebungsbedingungen erfüllen, die den Einbau des Blendrahmens aus Hohlprofilen in der Bauausnehmung erreichen.Two flow openings are to be provided to the outside (not: directed), with a view of the wing as parting plane, "outside" in the sense of the weather-dependent side. Two flow openings are to be placed on the inside ("inside" overlooking the living area). These four flow-opening areas, two of which are outlets, two of which are suction, are distributed to the ventilation unit so that they are favorable flow, let the window ventilation device small in construction and at the same time meet environmental conditions, the installation of the frame of hollow sections reach in the Bauausnehmung.

Erfindungsgemäß ist das Fenster-Lüftungsgerät einfach zu warten, was zum Auswechseln von Filtern oder Wärmetauscher-Elementen oder Elektronikbauteilen von Zeit zu Zeit erforderlich ist.According to the invention, the window ventilation device is easy to maintain, which is required for replacement of filters or heat exchanger elements or electronic components from time to time.

Erfindungsgemäß ist das Fenster-Lüftungsgerät auch geeignet, in einem Mittelpfosten (im Sinne eines Verbreiterungsprofils) platziert zu werden. Die außerhalb des Rahmens gelegene Auskragung ist dabei nicht zu groß.According to the invention, the window ventilation device is also suitable for being placed in a center post (in the sense of a broadening profile). The out-of-frame cantilever is not too big.

Die Strömungen und ihre Richtungen sind für außen und innen im Sprachgebrauch (in Deutschland) normiert. Angesaugte Außenluft (AU) tritt ein und wird im Lüftungsgerät konditioniert. Die Konditionierung durch Erwärmung erfolgt durch die aus dem Innenraum abgesaugte "alte" Innenluft, die beim Ansaugen Abluft heißt (AB). Die am Ende dieses Weges nach außen abgegebene Fortluft (FO) ergibt sich. Auf der Innenseite heißen die beiden Strömungsrichtungen Abluft (AB) für die aus dem Raum vom Fenster-Lüftungsgerät angesaugte "schlechte" Luft, dagegen ist die in den Raum eingeblasene Zuluft (ZU), die angesaugte Außenluft (AU), konditioniert und erwärmt als neue Raumluft, die in den Innenraum eingeblasen wird. Die Konditionierung (Erwärmung) erfolgt mit der kreuzenden oder vorbeiströmenden Abluft (AB). AB konditioniert AU für ZU und wird FO.The currents and their directions are standardized for outside and inside in the usage of language (in Germany). Sucked outside air (AU) enters and is conditioned in the ventilation unit. The conditioning by heating takes place through the "old" inside air extracted from the interior, which is called exhaust air when sucked in (AB). The exhaust air (FO) emitted to the outside at the end of this path results. On the inside, the two flow directions are called exhaust air (AB) for those out of the room from the window ventilation unit sucked "bad" air, on the other hand is the supply air blown into the room (ZU), the sucked outside air (AU), conditioned and heated as new room air, which is blown into the interior. The conditioning (heating) takes place with the exhaust air flowing through or passing by (AB). AB conditions AU for ZU and becomes FO.

Sofern in der folgenden Beschreibung unterschiedliche oder abweichende Begriffe verwendet werden, sind sie sinngemäß zu interpretieren. Angesaugte Außenluft, nach außen abgegebene Fortluft betreffen den Außenraum. Eingeblasene Innenluft und aus dem Raum abgesaugte Abluft betreffen den Innenraum. Es sind immer zumindest beide Begriffspaare zum Verständnis zu verwenden, die Richtung und der Ort (AN/AB und innen/außen). Sofern dabei die normierten Begriffe Außenluft, Fortluft, Zuluft und Abluft nicht immer harmonisiert verwendet werden, sind sie gemäß den hier gemachten Angaben sinngemäß im physikalischen Zusammenhang zu interpretieren.If different or different terms are used in the following description, they shall be interpreted analogously. Aspirated outside air, exhaust air discharged to the outside affect the outside space. Blown inside air and exhaust air extracted from the room affect the interior. At least both pairs of terms are always to be used for understanding, the direction and the place (AN / AB and inside / outside). If the standardized terms outside air, exhaust air, supply air and exhaust air are not always used in a harmonized manner, they must be interpreted in the physical context in accordance with the information given here.

Soweit von einem Fenster-Lüftungsgerät gesprochen wird, ist der Begriff des Fensters auch als Fenstertür oder Tür als solche zu sehen. Der Begriff des Fensters ist funktionell zu betrachten, also mit einem Glas-Einsatz versehen, der gemäß Aufgabe nicht verkleinert werden soll und gleichzeitig Lüftungsmöglichkeit an seinem Profilrahmen (Festrahmen) erreichen soll.As far as a window ventilation device is spoken, the term of the window is also to be seen as a French door or door as such. The term of the window is functional to look at, so provided with a glass insert, which should not be reduced according to task and at the same time to achieve ventilation on his profile frame (fixed frame).

Sensoren können vorgesehen sein. Zwei Sensoren können in Verbindung mit der elektrischen Schaltung auf der Platine zur Erkennung der Einbaulage des Lüftungsgeräts, als rechts oder links am Profilrahmen (Blendrahmen) angebauten "Gerät" dienen, ohne vorher in der Fertigung das rechte oder linke Gerät definieren zu müssen. Es kann also nur eine Gerätetype, die sich beim Einbau automatisch auf rechts oder links einstellt, gefertigt werden.Sensors can be provided. Two sensors can be used in conjunction with the electrical circuit on the board to detect the installation position of the ventilation unit, as a "device" mounted on the right or left of the profile frame (frame) without having to define the right or left device in the production. Thus, only one device type, which automatically adjusts to the right or left during installation, can be manufactured.

Temperatursensoren für eine Frostschutzstrategie können auch vorhanden sein, um das Lüftungsgerät im Betrieb vor Vereisung zu schützen.Temperature sensors for an antifreeze strategy may also be present to protect the ventilation unit from icing during operation.

Die Frostschutzstrategie zur Vermeidung eines Vereisens des Lüftungsgeräts durch steuerungstechnische Maßnahmen ist wie folgt.The antifreeze strategy for avoiding icing of the ventilation unit by control measures is as follows.

Um ein Vereisen des Wärmeübertragers (Wärmetauscher-Einsatzes) zu verhindern, ist ein Temperatursensor im Fortlufttrakt (dem Kanal, der die Luft nach außen führt) angeordnet. Da vor dem endgültigen Einbau nicht bekannt ist, ob das Lüftungsgerät rechts oder links am Festrahmen (Blendrahmen) montiert wird, können zwei Temperatursensoren, einer im beispielsweise jeweils äußersten Strömungskanal angebracht sein. Bei der Endmontage stellt ein Monteur am Gerät ein, ob es sich um ein linkes oder rechtes Lüftungsgerät handelt und die Steuerung wählt dazu den richtigen Sensor als "Fortluftsensor" aus (Sensor für die nach außen abgegebene Fortluft FO).In order to prevent icing of the heat exchanger (heat exchanger insert), a temperature sensor in the exhaust air duct (the channel that leads the air to the outside) is arranged. As it is not known before the final installation, whether the ventilation unit is mounted on the right or left of the fixed frame (frame), two temperature sensors, one in each example outermost flow channel attached be. During final assembly, an installer adjusts the unit to a left or right ventilation unit, and the control system selects the correct sensor as the "outgoing sensor" (FO outward sensor).

Die elektronische/elektrische Steuerung arbeitet mit einer Hysterese von wenigen °C, beispielsweise zwischen 2°C bis 4°C.The electronic / electrical control operates with a hysteresis of a few ° C, for example between 2 ° C to 4 ° C.

Wenn die Fortlufttemperatur (die Temperatur der Fortluft FO) im Betrieb unter einen eingestellten ersten Wert von z. B. 2°C sinkt, regelt die elektronische Steuerung auf der Platine in Abhängigkeit von einer Ventilatorstufe (Drehzahl) den Zuluftventilator herunter (Ventilator für die Luft ZU), insbesondere ganz aus.When the exhaust air temperature (the temperature of the exhaust air FO) in operation below a set first value of z. B. 2 ° C drops, the electronic control on the board in response to a fan speed (speed) down the supply fan (fan for the air CLOSED), in particular completely off.

Wenn die Fortlufttemperatur wieder auf einen größeren Wert, z. B. ca. 4°C angestiegen ist, wird der Zuluftventilator wieder auf der gleichen Stufe (mit der gleichen Drehzahl) wie der Abluftventilator (der Ventilator der Abluft AB, die nach dem Wärmetauscher die Fortluft FO ist) betrieben.If the exhaust air temperature returns to a higher value, eg. B. has risen about 4 ° C, the supply air fan is again at the same stage (at the same speed) as the exhaust fan (the fan of the exhaust air AB, which is the exhaust air FO after the heat exchanger).

Strategie zur Vermeidung von Zuluftüberschuss ist in Anspruch 13 beschrieben.Strategy for avoiding excess air supply is described in claim 13.

Da das Lüftungsgerät symmetrisch aufgebaut sein kann und vor der Endmontage nicht feststeht, wie es eingebaut wird, kann eine Möglichkeit gegeben sein, dass das Gerät die Volumenströme auf den jeweiligen Modus (rechts/links) abstimmt. Der Monteur stellt daher beim Einbau des Gehäuses ein, ob es sich um einen rechten oder linken Einbau handelt.Since the ventilation unit can be of symmetrical design and it is not known before final assembly how it is installed, there may be a possibility that the unit tunes the volume flows to the respective mode (right / left). The installer therefore adjusts when installing the housing, whether it is a right or left installation.

Die auf der Platine befindliche Elektronik kann die Ventilatoren damit so regeln, dass der jeweils oben liegende Ventilator als Abluftventilator und der untere als Zuluftventilator betrieben wird. Der Zuluftventilator wird auf eine etwas geringere Drehzahl eingestellt, so dass sichergestellt ist, dass kein Zuluftüberschuss im Innenraum (Auslass von ZU) entsteht.The on-board electronics can regulate the fans so that the top fan is operated as an exhaust fan and the bottom fan as a supply fan. The supply air fan is set to a slightly lower speed, so that it is ensured that there is no supply air surplus in the interior (outlet from CLOSED).

Ausführungsbeispiele der Erfindung werden im Folgenden beschrieben. Sie erleichtern und Ergänzen das Verständnis der beanspruchten Erfindung.

Figur 1
ist eine Stirnansicht eines Fester-Lüftungsgeräts 1 auf seine Stirnseite. Dieses Gerät besitzt ein Gehäuse 10 mit vier Öffnungen 12 bis 15, die Einlass- oder Auslass für eine Luftströmung sind.
Figur 2
veranschaulicht einen Schnitt A-A aus Figur 1, also in Längsrichtung des Gehäuses 10 und senkrecht zur Stirnseite. In dieser Schnittansicht ist der innere Aufbau der Strömungswege zu sehen, ein Strömungsweg S1 und ein zweiter Strömungsweg S2, die sich im Beispiel der Figur 2 kreuzen. Der Kreuzungsbereich ist 9 und an dieser Stelle ist ein Wärmetauscher 30 platziert.
Figur 3
ist eine Explosionsdarstellung des Geräts der Figur 1, mit allen Komponenten, die für die Funktion tragend sind. Das Gehäuse 10 nimmt diese Elemente auf und enthält Wände, die Bahnführungen definieren, unter anderem für die Strömungswege S1 und S2.
Figur 4
ist der eingebaute Zustand eines Lüftungsgeräts 1 an einem fest stehenden Rahmen 8, der im Ausschnitt dargestellt ist. Es sind Hohlkammern H1, H2, H3 in Längsrichtung ersichtlich, die zur Luft-Strömungsführung verwendet werden, was hier aber nicht näher erläutert wird. Sichtbar sind nur zwei laterale Strömungsöffnungen, von denen S2e die Ausströmöffnung in den Innenraum ist und die Strömungsöffnung S1a ist die Ansaugöffnung für die aus dem Innenraum zu entnehmende Abluft AB. Diese werden in entsprechenden Hohlkammern (als Kanäle) des Rahmenprofils geleitet und gelangen zu den Strömungswegen S1 und S2 des angebauten Fenster-Lüftungsgeräts 1 mit seinem Gehäuse 10 (oder stammen von diesen Strömungswegen im Gerät 1).
Embodiment examples of the invention will be described below. They facilitate and supplement the understanding of the claimed invention.
FIG. 1
is an end view of a fixed ventilation device 1 on its front side. This device has a housing 10 with four openings 12 to 15 which are inlet or outlet for air flow.
FIG. 2
illustrates a section AA FIG. 1 , ie in the longitudinal direction of the housing 10 and perpendicular to the end face. In this sectional view, the inner structure of the flow paths can be seen, a flow path S1 and a second flow path S2, which in the example of the FIG. 2 cross. The crossing area is 9 and at this point a heat exchanger 30 is placed.
FIG. 3
is an exploded view of the device FIG. 1 , with all the components that are responsible for the function. The housing 10 receives these elements and includes walls that define web guides, including the flow paths S1 and S2.
FIG. 4
is the installed state of a ventilation device 1 on a fixed frame 8, which is shown in the cutout. There are hollow chambers H1, H2, H3 seen in the longitudinal direction, which are used for air flow guidance, which will not be explained in detail here. Only two lateral flow openings are visible, of which S2e is the outflow opening into the interior, and the flow opening S1a is the intake opening for the exhaust air AB to be taken from the interior. These are passed in corresponding hollow chambers (as channels) of the frame profile and reach the flow paths S1 and S2 of the attached window ventilation device 1 with its housing 10 (or originate from these flow paths in the device 1).

Mit Figur 4 ist besonders deutlich ersichtlich, dass nur ein geringer Abschnitt des Fenster-Lüftungsgeräts mit seinem Gehäuse 10 in den Profil-Rahmen 8v tatsächlich eingreift, oder sogar nur berührend an einem Flächenabschnitt (nach links weisend) anliegt. Die zu diesem vertikalen Profilholm 8v weisenden Öffnungsbereiche 12, 13, 14 und 15 der Stirnseite 10d der Figur 1 übernehmen die Luftführung (Lufteintritt oder Luftaustritt). With FIG. 4 is particularly clear that only a small portion of the window ventilation device actually engages with its housing 10 in the profile frame 8v, or even only touching a surface portion (facing left) is applied. The opening portions 12, 13, 14 and 15 of the end face 10d facing the vertical profile spar 8v FIG. 1 take over the air duct (air intake or air outlet).

Auch an Figur 4 ersichtlich ist die kompakte Baugröße des Lüftungsgeräts 1, welches eine Erstreckung von a1' als Auskragung, eine Breite a3 und eine Höhe a2 aufweist. Im ausgebauten Zustand hat das Gehäuse 10 ein Quermaß von a1.Also on FIG. 4 the compact size of the ventilation device 1, which has an extent of a1 'as a projection, a width a3 and a height a2, can be seen. When removed, the housing 10 has a transverse dimension of a1.

Die Maße a1, a2, a3 definieren das Volumen des Lüftungsgeräts 1, wobei zwei abgerundete Kanten 10a und 10b durch Wandabschnitte definiert werden, die gleichzeitig auf der Innenseite des Gehäuses 10 Strömungswege begrenzen, wie das am Schnitt der Figur 2 ersichtlich ist.The dimensions a1, a2, a3 define the volume of the ventilation device 1, wherein two rounded edges 10a and 10b are defined by wall sections which at the same time delimit flow paths on the inside of the housing 10, as at the intersection of the FIG. 2 is apparent.

Das Fenster-Lüftungsgerät 1 mit seinem Gehäuse 10 und den beiden Strömungswegen S1 und S2 soll mit den übrigen Figuren näher erläutert werden.The window ventilation device 1 with its housing 10 and the two flow paths S1 and S2 will be explained in more detail with the other figures.

Die Rückwand 10c (an der linken Seite), die sich an die beiden gebogenen Wände 10a und 10b anschließt, ist das am Weitesten herausragende Stück oder Flächenstück des Fenster-Lüftungsgeräts. Dieses kann von einer bauseits vorgesehenen Mauerausnehmung aufgenommen werden, ohne dass der vertikale Rahmenabschnitt 8v selbst verbreitert werden muss, um das Lüftungsgerät aufzunehmen. Fensterfläche 7 geht dabei nicht verloren.The rear wall 10c (on the left side), which adjoins the two curved walls 10a and 10b, is the most projecting piece or patch of the window ventilation apparatus. This can be accommodated by a wall recess provided on site, without the vertical frame section 8v itself having to be widened to accommodate the ventilation device. Window area 7 is not lost.

Als Orientierung soll das eingeführte Koordinatensystem x, y und z gemäß Figur 4 (linkes Eck des Glaseinsatzes 7) dienen.As an orientation, the introduced coordinate system x, y and z according to FIG. 4 (left corner of the glass insert 7) serve.

Zu Figur 4 wäre noch zu sagen, dass die Bewegung des Glaseinsatzes 7 durch einen inneren Flügelrahmen ermöglicht ist, der an nicht dargestellten Scharnieren oder Gelenken oder Lagern in einer beliebigen Form eines Fensters oder einer Tür oder eine Fenstertür gehalten sein kann. Der Festrahmen 8 als Profilrahmen 8v (vertikaler Abschnitt) und 8h (horizontaler Abschnitt) bleibt unbeweglich. Daher seine Benennung als Festrahmen.To FIG. 4 It should also be pointed out that the movement of the glass insert 7 is made possible by an inner casement which can be held on hinges or hinges or bearings, not shown, in any shape of window or door or French window. The fixed frame 8 as a profile frame 8v (vertical section) and 8h (horizontal section) remains immovable. Hence his naming as a fixed frame.

Das Lüftungsgerät 1 gemäß Figur 1 und Figur 2 ist angepasst, nur ein Stück weit in dieses Rahmenprofil 8 (vertikal 8v, horizontal 8h) eingefügt oder nur daran dichtend angefügt zu werden. Entsprechend sind die Öffnungsbereiche 12 bis 15 von einer Dichtung jeweils umgeben, oder aber von einer in einer umlaufenden Nut jeweils vertieft liegenden Dichtung umgeben, die eine luftmäßige Abdichtung mit Blick oder relativ zu dem vertikalen Abschnitt 8v des Festrahmens 8 ermöglichen (vertikaler Profilholm 8v oder einem Luft führenden Zwischenbauteil).The ventilation device 1 according to FIG. 1 and FIG. 2 is adapted to be just a little way into this frame profile 8 (vertical 8v, horizontal 8h) inserted or just attached to it sealingly. Accordingly, the opening portions 12 to 15 are each surrounded by a seal, or surrounded by a respective recessed groove in a circumferential groove, which is an air-tight seal with a view or relative to the vertical portion 8v allow the fixed frame 8 (vertical profile spar 8v or air-bearing intermediate component).

Der außerhalb des Rahmens verbleibende Abschnitt a1' des Gehäuses 10 ist in Figur 4 zu ersehen. Er hat die Erstreckung a1', die kleiner oder gleich dem Maß a1 in Figur 2 ist. Jedenfalls wird nicht mehr als maximal 5 % bis 25 % der Tiefe (Tiefenmaß a1) des Gehäuses 10 von dem vertikalen Rahmenprofil-Abschnitt 8v aufgenommen, wenn überhaupt. Bei a1 in einem Bereich von 120 mm bis 100 mm ist der aufgenommene Anteil zwischen 5 mm bis 25 mm, bei einem auskragenden Rest von a1' = 95 mm.The remaining outside of the frame portion a1 'of the housing 10 is in FIG. 4 to see. It has the extension a1 ', which is less than or equal to the dimension a1 in FIG. 2 is. In any event, no more than a maximum of 5% to 25% of the depth (depth dimension a1) of the housing 10 is received by the vertical frame profile section 8v, if any. For a1 in a range of 120 mm to 100 mm, the recorded proportion is between 5 mm to 25 mm, with a protruding remainder of a1 '= 95 mm.

In Figur 3 ist dazu das Stück a1" eingezeichnet, welches das Gerät 1 mit seiner vorderen Schmalseite 10d in den Rahmenprofil-Abschnitt 8v versenkt werden kann, wenn es nicht aufliegend montiert wird.In FIG. 3 For this purpose, the piece a1 "is shown, which the device 1 can be sunk with its front narrow side 10d in the frame profile section 8v, when it is not mounted on-the-rest.

Das Gehäuse 10 mit seinen Wandabschnitten, die sowohl das Gehäuse begrenzen, wie auch im Innenraum des Gehäuses die dargestellten Strömungswege S1 und S2 festlegen, sind mit 10a, 10b, 10c sowie flachseitig mit 10e und 10f benannt.The housing 10 with its wall sections which define both the housing and define the illustrated flow paths S1 and S2 in the interior of the housing are designated by 10a, 10b, 10c and on the flat side by 10e and 10f.

In der Ausführung der Figur 2 kreuzen sich die beiden Strömungswege S1 und S2. Die von ihnen geführte Luft wird indes nicht berührend gekreuzt, sondern unter Verwendung eines Wärmetauscher-Einsatzes 30 aneinander vorbeiströmend geführt, aber nicht berührend. Der Wärmetauscher 30 ist als Einsatzelement in den Kreuzungsbereich 9 eingesetzt, und die Führungslinien S1 und S2 zeigen, wie die Luft funktionell strömt, von innen nach außen, respektive von außen nach innen.In the execution of FIG. 2 the two flow paths S1 and S2 intersect. The air guided by them is, however, not touchingly crossed, but guided by using a heat exchanger insert 30 flowing past each other, but not touching. The heat exchanger 30 is inserted as an insert element in the crossing region 9, and the guide lines S1 and S2 show how the air flows functionally, from inside to outside, or from outside to inside.

In einem nicht dargestellten Beispiel können die Strömungswege im Bereich 9 auch nicht kreuzend aneinander vorbeigeführt werden, was anhand der Bahnführung nur des äußeren Strömungswegs und nur des inneren Strömungswegs ebenso ersichtlich ist, wobei die verwendeten Axiallüfter 20, 21 dann anders zu platzieren sind, einer in jedem Strömungsweg. Ein angepasstes Wärmetauscher-Element 30' (nicht gesondert dargestellt) ist dann zu verwenden.In an example, not shown, the flow paths in the area 9 can also be passed not crossing each other, which is also evident from the web guide only the outer flow path and only the inner flow path, the axial fans used 20, 21 are then placed differently, one in every flow path. An adapted heat exchanger element 30 '(not shown separately) is then to be used.

Die Strömung selbst wird von den beiden Axiallüftern 20, 21 ermöglicht, die an den beiden weiter innen liegenden Öffnungsbereichen 12,14 platziert sind, wie das aus Figur 2 und 3 ersichtlich ist. Der Axiallüfter 20 bedient den Strömungsweg S2. Der Axiallüfter 21 bedient den Strömungsweg S1. Die Axiallüfter sind jeweils am Einlass des Strömungsweges, also S2a und S1a (a für Anfang) angeordnet. Ein zusätzlicher Filter 22 bzw. 23 ist an dem jeweiligen Lüfter 20, 21 angeordnet.The flow itself is made possible by the two axial fans 20, 21, which are placed at the two inner opening regions 12, 14, like that FIG. 2 and 3 is apparent. The axial fan 20 operates the flow path S2. The axial fan 21 operates the flow path S1. The axial fans are respectively arranged at the inlet of the flow path, ie S2a and S1a (a for beginning). An additional filter 22 or 23 is arranged on the respective fan 20, 21.

Die weiteren beiden Öffnungsbereiche, die auch von den zwei ohnehin schon beabstandeten Öffnungsbereichen 12, 14 beabstandet sind und mit ihnen nicht überlappen, sind die Ausströmöffnungen 13 und 15. Sie sind das Ende des jeweiligen Strömungsweges S1 bzw. S2, wobei der Strömungsweg S1, bedient von dem Axiallüfter 21, über den Kreuzungsbereich 9 geführt zum Auslass S1e führt. Ist bei S1a die Abluft AB platziert, ergibt sich bei S1e die Fortluft FO.The other two opening areas, which are also spaced from the two already spaced opening portions 12, 14 and do not overlap with them, are the outflow openings 13 and 15. They are the end of the respective flow path S1 and S2, the flow path S1, operated from the axial fan 21, led over the crossing region 9 leads to the outlet S1e. If the exhaust air AB is placed at S1a, the exhaust air FO results at S1e.

In gleicher Weise oder sagen wir "funktionell vergleichbar" ist der andere Strömungsweg S2, ausgehend von dem anderen Axiallüfter 20 gestaltet. Hier beginnt der Strömungsweg bei S2a, führt über den Kreuzungsbereich 9 und endet am entfernteren, außen liegenden Öffnungsbereich 15 mit dem Auslass S2e (e für Ende). Ist der Lüfter 20 beispielweise der angesaugten Außenluft AU zugeordnet, führt er die angesaugte Außenluft über den Kreuzungsbereich 9 und das Wärmetauscher-Element 30, wo diese Luft konditioniert wird, dem Ausgang S2e für die in den Raum eingeblasene Zuluft ZU zu.In the same way or say "functionally comparable" is the other flow S2, designed from the other axial fan 20. Here, the flow path starts at S2a, passes over the crossing area 9 and ends at the more remote, outside opening area 15 with the outlet S2e (e for end). If the fan 20, for example, associated with the sucked outside air AU, he leads the sucked outside air through the crossing region 9 and the heat exchanger element 30, where this air is conditioned, the output S2e for the blown into the room supply air ZU.

Ersichtlich ist, dass jeweils ein nahe beieinander liegendes Paar von Öffnungsbereichen 12,13 bzw. 14,15 vorgesehen ist, die aber funktionell nicht zusammengehören, sondern unterschiedlichen Strömungswegen angehören.It can be seen that in each case a pair of opening areas 12, 13 and 14, 15, which are close to one another, is provided, but which do not belong together functionally, but belong to different flow paths.

Die Beabstandung dieser beiden Paare 12,13 und 14,15 erfolgt durch den Zwischenbereich 11, der als weiterer Öffnungsbereich für die Aufnahme des Wärmetauscher-Elements vorgesehen ist, um diesen in dem Kreuzungsbereich 9 austauschbar zu platzieren. Entsprechende Haltekanten und Aufnahmen (beispielsweise an der rückwärtigen Wand 10c als Aufnahmemulde 10c') fixieren oder halten das Wärmetauscher-Element 30 (zusätzlich).The spacing of these two pairs 12, 13 and 14, 15 takes place through the intermediate region 11, which is provided as a further opening region for receiving the heat exchanger element in order to place it interchangeably in the intersection region 9. Corresponding retaining edges and receptacles (for example, on the rear wall 10c as a receiving trough 10c ') fix or hold the heat exchanger element 30 (in addition).

Die weitere Öffnung 11 wird verschlossen durch eine Abdeckung 40, die muldenartig 43 ausgebildet ist und im Beispiel rechteckig gestaltet ist.The further opening 11 is closed by a cover 40, the trough-like 43 is formed and is designed rectangular in the example.

Die Abdeckung 40 hat eine Mulde 43, die zur Aufnahme einer Platine P geeignet ist, die mit elektrischen und elektronischen Bauelementen bestückt ist. Zusätzlich kann eine Abdeckung 41 vorgesehen sein, welche den offenen Raum 43 verschließt, in den die Platine eingelegt ist. Entsprechende Bahnführungen für elektrische Leitungen sind in Figur 3 ersichtlich, die auch bei geschlossener Abdeckung 41 in den Innenraum 43 führen und die Lüfter 20,21-von der Elektronik - gesteuert mit Strom versorgen.The cover 40 has a trough 43 which is suitable for receiving a board P, which is equipped with electrical and electronic components. In addition, a cover 41 may be provided, which closes the open space 43, in which the board is inserted. Corresponding web guides for electrical lines are in FIG. 3 can be seen, leading even with the cover 41 closed in the interior 43 and the fan 20,21-controlled by the electronics - supply power.

Mit der Platine P und ihren elektronischen/elektrischen Bauelementen, die nicht gesondert dargestellt sind, können die Axiallüfter 20,21 gesteuert werden, in ihrer Drehzahl gesteuert werden oder in Gestalt eines An/Aus-Betriebs.With the board P and its electronic / electrical components, which are not shown separately, the axial fans 20,21 can be controlled, are controlled in their speed or in the form of an on / off operation.

Die Platine P kann weitere technologische Funktionsaufgaben des Fenster-Lüftungsgeräts 1 übernehmen, so Steuerung der Vermeidung von Zuluftüberschuss, Temperatursteuerung, Temperaturüberwachung (Frost-/Vereisungsschutz des Wärmetauschers), Signalisierung, Wartungszustände, Wartungsintervalle und Lageerkennungen, die durch Anbringung geeigneter Sensoren an dem langgestreckten Gehäuse 10 in den Strömungswegen, bevorzugt an deren Enden, so platziert sind, dass das Gerät selbsttätig erkennt, in welcher Einbaulage es eingebaut ist, um Einlass/Auslass festzulegen, die den vier Öffnungsbereichen 12 bis 15 zugewiesen sind. Diese verändern sich je nach Einbaulage, und entsprechend können die Schaltung und ihre Sensoren auf die zu erkennende Einbaulage reagieren und das Fenster-Lüftungsgerät 1 funktionell entsprechend einstellen, und zwar automatisiert.The board P can take over other technological functions of the window ventilation device 1, so control of avoidance of supply air excess, temperature control, temperature monitoring (frost / icing protection of the heat exchanger), signaling, maintenance conditions, maintenance intervals and location detections by attaching appropriate sensors to the elongated housing 10 in the flow paths, preferably at their ends, are placed so that the device automatically recognizes in which mounting position it is installed to define inlet / outlet, which are assigned to the four opening areas 12 to 15. These vary depending on the installation position, and accordingly, the circuit and its sensors can respond to the installation position to be detected and the window ventilation device 1 functionally set accordingly, namely automated.

Die Stirnseite 10d ('vordere' Schmalseite) ist die funktionstragende Seite, die anderen Seiten sind eher passive Seiten. Alle Strömungen enden und beginnen an der Stirnseite, der Wärmetauscher 30 wird hier eingesetzt, entnommen und ausgetauscht. Die Platine wird hier platziert, ausgetauscht, repariert oder neu eingesetzt, und auch die Filterplatten 22,23 für die Lüfter werden hier platziert und/oder ausgetauscht oder gewartet.The front side 10d ('front' narrow side) is the functional side, the other sides are more passive sides. All flows end and start at the front, the heat exchanger 30 is used here, removed and replaced. The board is placed here, replaced, repaired or reused, and also the filter plates 22,23 for the fans are placed here and / or replaced or maintained.

Die gesamte Wartung des Fenster-Lüftungsgeräts geschieht von der (schmalen) Stirnseite 10d aus. Die gesamte Funktion erfolgt ebenfalls von dieser Schmalseite (Stirnseite) aus.The entire maintenance of the window ventilation device is done from the (narrow) end face 10d. The entire function also takes place from this narrow side (front side).

In der genauen Ausgestaltung kann der Wärmetauscher-Einsatz 30 sechseckig ausgebildet werden, wobei zwei Flächenbereiche die Platzierung bei der Aufnahmemulde 10c' und bei der eingesetzten Abdeckung 40 übernehmen, und jeweils zwei geneigte Flächenabschnitte den Anschluss an das jeweilige Ende einer jeweils gekrümmten Führungswand bilden, so dass die zwei geneigt verlaufenden Endbereiche des Wärmetauschers der linken oder rechten Seite der Figur 2 jeweils zwei Einlass/Auslass-Bereiche definieren, durch welche die Strömungsführung der Luft erfolgt. Der Wärmetauscher definiert damit einen abgeschlossenen Bereich im Kreuzungsbereich 9, der von zwei Strömungswegen durchkreuzt wird, wobei der Wärmetauscher 30 selbst aus einer Vielzahl von aufeinanderliegenden Platten gestaltet ist, so dass sich eine abwechselnde Schichtung der durchströmenden Luft ergibt und damit ein Gegenstrom-Wärmetauscher mit hoher Effizienz verwendet werden kann.In the exact embodiment of the heat exchanger insert 30 can be formed hexagonal, with two surface areas take over the placement in the receiving trough 10c 'and the cover used 40, and two inclined surface portions form the connection to the respective end of a respective curved guide wall, so that the two inclined end portions of the heat exchanger of the left or right side of FIG. 2 each defining two inlet / outlet areas through which the flow of air is carried out. The heat exchanger thus defines a closed region in the crossing region 9, which is crossed by two flow paths, wherein the heat exchanger 30 itself is formed of a plurality of superimposed plates, so that there is an alternating layering of the air flowing through and thus a countercurrent heat exchanger with high Efficiency can be used.

Der Wärmetauscher-Einsatz 30 wird vollständig von dem Gehäuse 10 aufgenommen. Er schließt an die gehäuseinternen Strömungswege an, in die er einschiebbar ist. Ebenso kann der Wärmetauscher aber zu Wartungszwecken herausgenommen werden, oder bei Beschädigung oder Ende seines Lebenszyklusses vollständig ausgetauscht werden. In gleicher Weise sind auch die Axiallüfter 21,20 austauschbar, oder aber die Filterplatten 22,23, die mit einem Netz versehen sein können, um grobe Schwebestoffe herauszufiltern.The heat exchanger insert 30 is completely received by the housing 10. It connects to the in-house flow paths into which it can be inserted. Likewise, the heat exchanger can be removed for maintenance purposes, or completely replaced if damaged or end of its life cycle. In the same way, the axial fans 21,20 are exchangeable, or the filter plates 22,23, which may be provided with a network to filter out coarse suspended matter.

Werden zwei Strömungswege S1 und S2 verwendet, werden nicht mehr als zwei Axiallüfter 21,22 benötigt. Diese Lüfter sind bevorzugt am Einlass eines jeweiligen Strömungswegs platziert.If two flow paths S1 and S2 are used, no more than two axial fans 21, 22 are required. These fans are preferably placed at the inlet of a respective flow path.

Die besondere Ausgestaltung der Figur 2 zeigt die beiden Axiallüfter an den beiden weiter innen liegenden Öffnungsbereichen 12,14. Dies ist eine mögliche Ausgestaltung, die auch invertiert werden kann, so dass die beiden außen liegenden Öffnungsbereiche 13,15 die beiden Axiallüfter 20,21 tragen. Eine entsprechende Bahnführung des jeweiligen Strömungswegs S1 und S2 wird dann durch entsprechend geformte Wandabschnitte innerhalb des Gehäuses 10 realisiert.The special embodiment of FIG. 2 shows the two axial fans at the two further inner opening portions 12,14. This is a possible embodiment, which can also be inverted, so that the two outer opening regions 13, 15 carry the two axial fans 20, 21. A corresponding web guide of the respective flow path S1 and S2 is then realized by correspondingly shaped wall sections within the housing 10.

Es war auch angesprochen worden, dass der Kreuzungsbereich 9 nicht zwingend ist, wie in der Figur 2 dargestellt. Ebenso können Wärmetauscher als Einsatzelemente verwendet werden, die eine parallele Führung (kein Kreuzen der Strömungswege S1/S2) realisieren.It had also been mentioned that the crossing area 9 is not mandatory, as in the FIG. 2 shown. Likewise, heat exchangers can be used as insert elements, which realize a parallel guidance (no crossing of the flow paths S1 / S2).

In einer solchen modifizierten Ausgestaltung, die nicht gesondert dargestellt ist, ist ein weiteres Ausführungsbeispiel zu sehen.In such a modified embodiment, which is not shown separately, a further embodiment can be seen.

Weitere Möglichkeiten der Platzierung der Axiallüfter liegen darin, beide Axiallüfter auf der weiter links liegenden Seite zu platzieren oder beide Axiallüfter auf der weiter rechts liegenden Seite so zu platzieren, dass die beiden Öffnungsbereiche 12,13 je einen Axiallüfter erhalten oder in einer anderen Ausführung die beiden Öffnungsbereiche 14,15 je einen Axiallüfter tragen. Die Bahnführungen der Strömungswege S1' und S2' (nicht gesondert dargestellt) sind dann entsprechend zu wählen.Further possibilities for the placement of the axial fans are to place both axial fans on the side further to the left or to place both axial fans on the side further to the right so that the two opening regions 12, 13 each receive an axial fan or in another embodiment the two Opening areas 14,15 each wear an axial fan. The web guides of the flow paths S1 'and S2' (not shown separately) are then to be selected accordingly.

Alle aufgeführten Möglichkeiten der Platzierung der verschiedenen Lüfter, der Kreuzung oder der Nicht-Kreuzung sind miteinander austauschbar.All listed ways of placing the various fans, intersection or non-intersection are interchangeable.

Es versteht sich an der bildlichen Darstellung, dass die geeignete Wahl der Form der Öffnungsbereiche ein Rechteck ist. Dies ist zumindest für diejenigen Öffnungsbereiche 12,14 günstig, die mit einem Axiallüfter versehen sind. Die anderen, eher in der Gestaltung freier zu wählenden Öffnungsbereiche 15,13 sind aus Gründen der Ergonomie im Beispiel auch viereckig gestaltet. Andere Formen sind indes ebenso möglich, beispielsweise auch abgerundete Formen. Maßgebend ist allein, dass funktionelle(r) Öffnungsbereich(e) vorhanden ist/sind, der/die einen Strömungs-Auslass oder einen Strömungs-Einlass für die zu führende Luft ermöglicht.It is understood from the pictorial representation that the appropriate choice of the shape of the opening areas is a rectangle. This is favorable at least for those opening areas 12, 14 that are provided with an axial fan. The other, more in the design of free to choose opening areas 15,13 are designed for reasons of ergonomics in the example also quadrangular. However, other forms are also possible, for example, rounded shapes. The only thing that matters is that functional opening area (s) is present that allows a flow outlet or flow inlet for the air to be supplied.

Ebenso ersichtlich an den Beispielen ist, dass die Wand des Gehäuses 10 dünn ausgestaltet ist, nicht mehr als mit einer Materialstärke von 2 bis 5 mm Stärke. Nur an Montagebereichen können stärkere Abschnitte auftreten, wie im Bereich 48,49, der Anschlussflansche festlegt, die mit Muffen 48a,49a an dem vertikalen Rahmenabschnitt 8v zu montieren sind. Die stärkeren Bereiche 49/48 sind an der oberen und unteren Wand 10g und 10h vorgesehen.Also evident from the examples is that the wall of the housing 10 is made thin, not more than with a material thickness of 2 to 5 mm thickness. Only on mounting areas For example, stronger sections may occur, such as in section 48, 49, which defines connection flanges to be mounted with sleeves 48a, 49a on the vertical frame section 8v. The stronger portions 49/48 are provided on the upper and lower walls 10g and 10h.

Durch die Festlegung der Gehäuse-Wandstärke wird jeder der Öffnungsbereiche von stirnseitig mit einer Wandstärke des Gehäuses begrenzt. Diese Wandstärke des Gehäuses 12a,13a, 14a,15a kann mit einer Nut versehen sein, die eine eingelegte Dichtung aufnimmt. Die dichtende Anlagekante ist damit die Dichtung. Sie liegt an einer Fläche des Hohlprofils oder an einer Fläche eines weiteren Anschlussbauteils an, welches für die weitere Luftführung ausgebildet ist.By fixing the housing wall thickness, each of the opening areas is bounded by the front side with a wall thickness of the housing. This wall thickness of the housing 12a, 13a, 14a, 15a may be provided with a groove which receives an inserted seal. The sealing contact edge is thus the seal. It is located on a surface of the hollow profile or on a surface of another connection component, which is designed for the further air flow.

Ist eine Dichtung nicht gesondert vorgesehen, kann die Gehäusewand auch direkt an oder ein Stück weit in den vertikalen Abschnitt 8v des Profilrahmens eingreifen oder anliegen. Die "dichtende Anlagekante" für den Flächenbereich dieses Rahmenprofils dient der Fortführung des jeweiligen Strömungswegs aus den Strömungswegen S1 und S2 des Gehäuses 10 in die oder von den Hohlkammern H1, H2, H3 des Rahmenprofils.If a seal is not provided separately, the housing wall can also engage or abut directly on or a little way into the vertical section 8v of the profile frame. The "sealing contact edge" for the surface area of this frame profile serves to continue the respective flow path from the flow paths S1 and S2 of the housing 10 into or from the hollow chambers H1, H2, H3 of the frame profile.

Für die genaue Ausführung der Axiallüfter 20,21 und der zugehörigen Filterscheiben (oder Filterplatten) versteht sich, dass die Lüfter so gestaltet sind, dass sie in die zugehörigen Öffnungsbereiche 12,14 passen und dort aufgenommen werden können, gegebenenfalls unter Hinzunahme einer umlaufenden (elastomeren) Rahmendichtung (nicht dargestellt in Figur 3, aber sinngemäß ersichtlich als 20a und 21a in Figur 2). Ebenso die sie nach außen abdeckende Filterplatte (oder Filterscheibe), die vor den Axiallüftern platziert sind und nicht von der Stirnseite 10d vorstehen, sondern ebenso vollständig von dem jeweiligen Öffnungsbereich aufgenommen wird.For the exact design of the axial fans 20,21 and the associated filter discs (or filter plates) is understood that the fans are designed so that they fit into the associated opening portions 12,14 and can be recorded there, optionally with the addition of a circumferential (elastomeric ) Frame gasket (not shown in FIG. 3 , but mutatis mutandis apparent as 20a and 21a in FIG. 2 ). Likewise, the filter plate (or filter disc) covering it to the outside, which are placed in front of the axial fans and not protrude from the end face 10d, but is also completely absorbed by the respective opening area.

Ist die Außenfläche des vertikalen Hohlprofils 8v eine ebene Fläche, enden alle Stirnkanten 13a,12a,14a und 15a der vier Öffnungsbereiche in einer funktionellen Montageebene M, die ein Aufsetzen des Gehäuses 10 auf die Außenfläche des Hohlprofils definiert.If the outer surface of the vertical hollow profile 8v is a flat surface, all the end edges 13a, 12a, 14a and 15a of the four opening regions end in a functional mounting plane M which defines a seating of the housing 10 on the outer surface of the hollow profile.

Die Größenbemessung für ein kompaktes Lüftungsgerät 1, festgelegt durch die Außenabmessung des Gehäuses 10, können für die verschiedenen Anwendungsbereiche umschrieben werden.The sizing for a compact ventilation device 1, determined by the outer dimension of the housing 10, can be described for the various areas of application.

Kompakt heißt, dass das Gerät in seiner größten Erstreckung des Gehäuses 10 nicht länger als 700 mm ist, bevorzugt weniger als 550 mm als größtes Erstreckungsmaß besitzt. Dies ist das erste, größte Maß. Diese Größe ist kleiner als der Abstand von Riegelzapfen, oder aber dem maximalen Schraubabstand des profilierten Festrahmens. Das Gerät soll sich in Längsrichtung so in seine funktionelle Umgebung einfügen, dass es als kompakt benannt jedenfalls keine Modifikation einer normalen Montage erfordern würde und schlimmstenfalls auch nicht erzwingt.Compact means that the device in its greatest extent of the housing 10 is not longer than 700 mm, preferably less than 550 mm has the greatest extent extent. This is the first, biggest measure. This size is smaller than the distance of locking pin, or the maximum screw spacing of the profiled fixed frame. The device should fit longitudinally into its functional environment so that it would not require any modification of a normal assembly in any case, and in the worst case would not force it.

Kompakt ist das Gehäuse 10 (und damit auch das Lüftungsgerät 1) auch deshalb, weil es für Profiltiefen des Festrahmens von weniger als 100 mm, bevorzugt weniger als 80 mm angepasst und geeignet ist. Bevorzugt hat das kompakte Lüftungsgerät 1 ein Breitenmaß a3 (in Richtung der Profiltiefe) von weniger als 80 mm. Dies ist das kleinste, dritte Maß.Compact is the housing 10 (and thus also the ventilation unit 1) also because it is adapted and suitable for profile depths of the fixed frame of less than 100 mm, preferably less than 80 mm. Preferably, the compact ventilation device 1 has a width dimension a3 (in the direction of the tread depth) of less than 80 mm. This is the smallest, third measure.

Es verbleiben im eingebauten Zustand als aus dem Rahmenprofil seitlich herausragender Abschnitt a1' des Gehäuses 10 nicht mehr als 100 mm. Dies passt sogar in ein Verbreiterungsprofil eines Mittelpfostens, der jedenfalls erzwingt, dass weniger als 100 mm Bauraum nur zur Verfügung stehen. Auch hier soll das Gehäuse 10 und damit das Lüftungsgerät 1 einpassbar und einbaubar sein.It remain in the installed state as from the frame profile laterally projecting portion a1 'of the housing 10 is not more than 100 mm. This even fits in a broadening profile of a center post, which in any case forces that less than 100 mm of space available only. Again, the housing 10 and thus the ventilation device 1 should be adjustable and installable.

Dies ist das mittlere, zweite Maß a1, das kleiner als a2 und größer als a3 ist. Ein Stück des zweiten Maßes, absolut zwischen 5 mm und 20 mm und relativ zu a1 zwischen 5 % und 25 % kann in den Profilrahmen eingesetzt sein und reduziert die auskragende Länge a1' auf weniger als 100 mm.This is the middle, second measure a1, which is smaller than a2 and larger than a3. A piece of the second dimension, absolutely between 5 mm and 20 mm and relative to a1 between 5% and 25%, can be inserted in the profile frame and reduces the projecting length a1 'to less than 100 mm.

Alle Maßwerte sind dabei als "praktische Maße" mit ein wenig Toleranz (zumindest ± 1 %) zu sehen.All measurements are to be seen as "practical dimensions" with a little tolerance (at least ± 1%).

Die Ausführungsformen erfüllen die Umfeld-Bedingungen dadurch, dass das Gehäuse maximal ein Stück weit in das Profil des Festrahmens (Blendrahmen) eingesetzt wird, wenn nicht sogar die Stirnebene 10d unmittelbar mit der Montageebene M auf die Außenfläche des vertikalen Flügelprofils 8v aufgesetzt wird.The embodiments meet the environmental conditions in that the housing is inserted a maximum of a little way into the profile of the fixed frame (frame), if not even the frontal plane 10d is placed directly to the mounting plane M on the outer surface of the vertical wing profile 8v.

Eine Quererstreckung des Gehäuses 10, senkrecht zur Ebene der genannten Schmalseite 10d ist im Sinne eines kompakten Aufbaus auch weniger als 80 mm. Das Gehäuse 10 erfordert es damit nicht, dass ein vollständiger Durchbruch der gesamten bauseitigen Wand notwendig ist, um das Lüftungsgerät zwischen der Rauminnenseite und der Raumaußenseite entlang der gesamten Wandtiefe zu platzieren, vielmehr genügt ein relativ klein zu benennender Bauraum, der von der Innenseite des Raumes ausgeht, aber die Außenseite nicht erreicht.A transverse extent of the housing 10, perpendicular to the plane of said narrow side 10d is in the sense of a compact construction also less than 80 mm. The housing 10 does not require it so that a complete breakthrough of the entire on-site wall is necessary to place the ventilation unit between the room inside and the room outside along the entire wall depth, but a relatively small to be designated space is sufficient, from the inside of the room goes out, but the outside is not reached.

Eine "Tiefenerstreckung" des Gehäuses 10 ist deshalb bevorzugt weniger als 80 mm. Die meisten Rahmenprofile 8 haben eine größere Tiefe und überbrücken den Raum zwischen der Innenfläche und der Außenfläche der Wand im Fenster- oder Türbereich.A "depth extension" of the housing 10 is therefore preferably less than 80 mm. Most frame profiles 8 have a greater depth and bridge the space between the inner surface and the outer surface of the wall in the window or door area.

Kompakte Geräte haben Maße, die unter 12 cm x 70 cm x 10 cm liegen, insbesondere unter 12 cm x 55 cm x 8 cm. Damit das Gerät selbst hoch effektiv ist, wird die gesamte Tiefe (in Erstreckungsrichtung der Stirnseite) für die Strömungsbahnen zur Verfügung gestellt. Dies entspricht dem Maß a3 in Figur 4 und erstreckt sich in Blickrichtung der Figur 2 "in die Tiefe".Compact devices have dimensions that are less than 12 cm x 70 cm x 10 cm, in particular less than 12 cm x 55 cm x 8 cm. In order for the device itself to be highly effective, the entire depth (in the extension direction of the face) is provided for the flow paths. This corresponds to the dimension a3 in FIG FIG. 4 and extends in the direction of the FIG. 2 "into the deep".
