Description

The invention relates to an arrangement for decentralized ventilation systems in the pitched roof area of buildings with a ventilation dormer adapted to the roof shape and/or roof tiles and a connection piece for a ventilation pipe penetrating the roof structure and leading into the interior of the building, wherein a heat recovery component and/or a fan can be inserted into the ventilation pipe, according to the preamble of claim 1.

Sound-insulating, decentralized ventilation systems with or without heat recovery and high volume flows are state of the art.

Ceramic bodies with a large number of flow channels are used as heat recovery components. Air flowing through them releases heat energy or absorbs heat energy when the direction is reversed.

In order to achieve the necessary volume flows, it is usually necessary to use fans, especially fans with reversible direction. Filter elements can also be used which are integrated into the flow path.

Roof ventilators are also well known, especially for building roofs covered with flat tiles.

The DE 199 00 316 A1 a roof ventilator, which should be architecturally integrated into the flat tile structure, so that a visually appealing design is achieved.

In this regard, the shape of the roof ventilator is designed in such a way that it corresponds to one or more flat tiles arranged in a composite. The roof ventilator is hollow and the top opening is made from the open narrow side on top. This makes it possible to create a low-profile ventilator dormer. A further development of the previously known solution consists in creating a step in the opening area, which prevents water from entering due to the effects of wind. The connection piece of the roof ventilator is located via a breakthrough in the roof structure, whereby the connection piece, preferably designed as a connection pipe, assumes an inclined position and thus leads into the interior of the building.

The roof ventilator described above for a roof covered with flat tiles and an opening on the underside and thus connected to the ventilation at the top solves the problem of integrating it into the roof tile composite as inconspicuously as possible, but there are no approaches to collecting condensate or moisture that forms or penetrates.

Based on the above, it is therefore the object of the invention to provide a further developed arrangement for decentralized ventilation systems in the pitched roof area of buildings with a ventilation dormer adapted to the roof shape and/or roof tiles, which ensures that condensate or moisture is retained, while at the same time providing the possibility of creating easy access to installed fans and/or heat recovery components. Pitched roof designs are understood to mean designs with an angle in the range between 30° and 60°. The solution according to the invention should dispense with an additional wall structure in the interior and the aforementioned condensate drain should be integrated into the ventilation system.

The object of the invention is achieved by an arrangement for decentralized ventilation systems in the pitched roof area of buildings according to the combination of features according to claim 1, wherein the subclaims represent at least expedient embodiments and further developments.

Accordingly, an arrangement for decentralized ventilation systems in the pitched roof area is assumed to have a pitched roof angle in the range of e.g. 30° to 60°, whereby the arrangement includes a ventilation dormer adapted to the roof shape and/or the roof tiles.

The ventilation dormer has a connection socket for a ventilation pipe that penetrates the roof structure and leads into the building.

A heat recovery component and/or at least one fan can be installed in the ventilation pipe to generate the necessary flow.

According to the invention, a connection area for a removable inner panel is formed at the end of the ventilation pipe on the inside of the building.

Furthermore, the connection area has a tub-like section with a drain to collect condensate or moisture.

According to the invention, an insert piece designed as a baffle plate is also provided, which retains the aforementioned condensate or moisture and directs it into the trough-like section.

The insert further comprises means for securing the heat recovery component and/or the fan.

If the insert is removed, easy access to the fan or heat recovery component is possible, ensuring uncomplicated assembly, disassembly or access for maintenance purposes.

According to one embodiment of the invention, the connection area is designed as a separate pipe section, which can be coupled to the ventilation pipe on the one hand and the inner panel on the other. This connection is usually made by plugging them into one another.

The connecting area or pipe section includes a funnel-like extension to form the trough-like section.

The funnel-like extension has a nozzle on the underside for connecting a hose or similar means for draining collected moisture.

The impact plate essentially follows the contour of the inside of the connection area and is adapted accordingly.

The impact plate can be inserted and fixed in a groove or recess in the connecting piece.

The impact plate has locking projections which are oriented in the longitudinal direction of the ventilation pipe in such a way that the heat recovery component and/or the fan in the ventilation pipe are held in an exchangeable manner. In one embodiment, the impact plate has a lower area which partially extends into the trough-like section and an upper area. This upper area has an arched recess. The height of the recess serves to safely hold back any penetrating water so that it does not reach beyond the trough-like area. On the other hand, however, the shape of the impact plate is selected in such a way that there is no adverse effect on the air flow or the flow path.

The locking projections are preferably formed in the upper area of the impact plate and secure their position in the ventilation pipe by coming into contact with a housing section of the fan or the heat recovery component.

The underside area of the impact plate has foot-like spacers pointing vertically away from the surface and extending towards the trough-like section in order to form a condensate flow channel into the trough-like section when the impact plate is inserted.

The invention will be explained in more detail below using an embodiment and with the aid of figures.

• 1a eine Seitenansicht der Anordnung mit Lüftungsrohr, Verbindungsbereich sowie Innenblende (die eigentliche Lüftergaube mit Anschlussstutzen ist nicht dargestellt);
• 1b eine Ansicht der Anordnung gemäß 1a von vorn (d. h. von der Gebäudeinnenseite aus) mit angedeutetem Ventilator sowie wannenartigen Abschnitt mit Ablauf für Kondensat oder Feuchtigkeit;
• 2a einen Längsschnitt durch ein als separates Rohrstück ausgebildeten Verbindungsbereich mit eingesetzter Prallplatte, wannenartigen Abschnitt und Ablauf zum Auffangen von Kondensat oder Feuchtigkeit;
• 2b einen Teilquerschnitt der Anordnung nach 2a mit Ansicht von vorn (Draufsicht) auf den wannenartigen Abschnitt mit eingesetzter Prallplatte;
• 3a eine Vorderansicht der Prallplatte mit oberseitigem Bereich, der eine Bogenform bzw. einen bogenförmigen Rücksprung aufweist sowie unterseitigen Bereich, an welchem fußartige Abstandshalter ausgebildet sind, um im eingebauten Zustand einen Kondensatströmungskanal (siehe auch 4) auszubilden;
• 3b eine Seitenansicht der Prallplatte gemäß 3a und
• 4 eine perspektivische Darstellung mit Ansicht hinein in den Verbindungsbereich mit wannenartigem Abschnitt und eingesetzter Prallplatte (zur besseren Erkennbarkeit in teilweggebrochener Darstellung).

Here we show:

• 1a a side view of the arrangement with ventilation pipe, connection area and inner panel (the actual ventilation dormer with connection nozzle is not shown);
• 1b a view of the arrangement according to 1a from the front (ie from the inside of the building) with an indicated fan and a tray-like section with a drain for condensate or moisture;
• 2a a longitudinal section through a connection area designed as a separate pipe section with an inserted baffle plate, trough-like section and drain for collecting condensate or moisture;
• 2 B a partial cross-section of the arrangement according to 2a with front view (top view) of the trough-like section with inserted impact plate;
• 3a a front view of the impact plate with an upper area which has an arched shape or an arched recess and an underside area on which foot-like spacers are formed in order to form a condensate flow channel when installed (see also 4 ) to train;
• 3b a side view of the impact plate according to 3a and
• 4 a perspective view with a view into the connection area with a trough-like section and an inserted impact plate (partially broken away for better visibility).

According to the representations after the 1a and 1b It is assumed that there is a ventilation pipe 1, in the interior of which (see partially broken-off part of the illustration) a heat recovery component 2 and/or a fan 3 can be arranged.

At the building-side end of the ventilation pipe 1 there is a connecting area 4 which carries a removable inner cover 5.

The connecting area 4 comprises a trough-like section 6 with drain 7 for collecting against condensate or moisture that forms or penetrates.

The connection area 4 can be designed as a pipe section 9 (see 2a and 2 B) The pipe section 9 can be connected to the ventilation pipe 1 and the inner panel 5 (see 1b) .

From the 2a and 2 B It can be seen that the connecting region 4 or the pipe section 9 comprises a funnel-like extension 10 for forming the aforementioned trough-like section 6.

The funnel-like extension 10 goes into the nozzle (11) (see also 1a and 1b) The nozzle 11 serves to connect a hose (not shown) or similar means to drain condensate or moisture which has collected in the extension 10.

From the overview of the 2a , 2 B , 3a and 3b It is clear that the impact plate 8 follows the contour of the inside of the connection area 4 or the pipe section 9 and is adjusted accordingly. The impact plate 8 can be fixed in the pipe section 9 and can be removed for the purpose of accessing the fan 3 or the heat recovery component 2.

To fix the heat transfer component 2 or the fan 3, the baffle plate 8 has locking projections 12 which are oriented in the longitudinal direction of the fan pipe 1 such that the heat recovery component 2 and/or the fan 3 are held in the ventilation pipe 1 in an exchangeable manner.

The pin-like respective locking extension 12 of the impact plate 8, as in 2a shown, thus forming a stop for, for example, a housing section of the fan 3.

As in particular the 4 can be removed, the impact plate 8 has a lower side 13, partially extending into the trough-like section 6, and an upper side 14 area, whereby this upper side area 14 has an arched recess 15 (see also 3a) includes.

The locking projections 12 are preferably formed in or on the upper region 14 of the impact plate 8.

The underside area 13 of the impact plate 8 has foot-like spacers 16 pointing perpendicularly away from its surface in order to form a condensate flow channel 17 (see 4 ) into the trough-like section 6.

Finally, it should be noted that all of the features disclosed are essential to the invention, including technical modifications of the design solutions described in the exemplary embodiments. The design of a baffle plate in the area of a condensate collecting tray for the arrangement presented is crucial for the invention, whereby the baffle plate serves not only to hold back moisture that would otherwise escape, but also to fix components located in the ventilation pipe, but also to ensure access to these components after the baffle plate has been removed. When and to the extent that we speak of a connecting pipe or pipe section, this does not mean that only components with a circular cross-section are meant. Rather, all relevant deviations in the cross-sectional shape or cross-sectional design are also included.
