Description

Die Erfindung betrifft einen Dachwassereinlauf mit einer Wassersammelmulde, die einen in einer Ebene eines Daches angeordneten Rand und einen im Abstand zu diesem Rand angeordneten Boden mit einer Öffnung aufweist und diese Öffnung zu einem unten am Boden angebrachten Ablauf führt und mit einem Ventil zur Regulierung der Ablaufleistung.The invention relates to a roof water inlet with a water collection well, which has a arranged in a plane of a roof edge and arranged at a distance to this edge bottom with an opening and this opening leads to a bottom mounted drain and with a valve for regulating the drainage performance ,

Dachwassereinläufe sind seit langem bekannt und werden insbesondere zur Entwässerung von Flachdächern und gefällschwachen Dächern verwendet. Beispielsweise offenbart die WO 95/15423 des Anmelders einen solchen Dachwassereinlauf. Dieser besitzt eine Wassersammelmulde und über dieser zwei Platten. Diese wirken als Umlenkplatten, sodass sich in der Ablaufleitung ein so genannte geschlossene Strömung bilden kann. Eine solche geschlossene Strömung hat den Vorteil, dass infolge einer Saugwirkung eine hohe Leistung erreicht werden kann. Der Durchmesser der Ablaufleitung kann dadurch kleiner sein, als ohne eine solche geschlossene Strömung.Roof drains have long been known and are used in particular for drainage of flat roofs and weak fuzzy roofs. For example, the WO 95/15423 the applicant such a roof water inlet. This has a water collection trough and above these two plates. These act as baffles so that a so-called closed flow can form in the drain line. Such a closed flow has the advantage that a high performance can be achieved due to a suction effect. The diameter of the discharge line can thereby be smaller than without such a closed flow.

Durch die EP 1 203 851 ist ein Dachwassereinlauf bekannt geworden, bei dem im Abstand zur Wassersammelmulde in einer Fallleitung ein Ablaufventil angeordnet ist. Dieses Ablaufventil wird mit einem Füllstandssensor geregelt, der in der Wassersammelmulde angeordnet ist. Das Ablaufventil ist so geregelt, dass die Ablaufleitung wenigstens angeordnet ist. Das Ablaufventil ist so geregelt, dass die Ablaufleitung wenigstens teilweise immer mit Wasser gefüllt ist. Dadurch ist es möglich, die Ablaufgeräusche zu vermindern. Zudem lässt sich die mechanische Belastung bei hoher Leistung infolge von dynamischen Schwankungen verringern. Dieser Dachwassereinlauf ist in der Herstellung jedoch vergleichsweise aufwändig.By the EP 1 203 851 a roof water inlet has become known in which a drain valve is arranged at a distance from the water collection well in a downpipe. This drain valve is controlled by a level sensor located in the water collection well. The drain valve is regulated so that the drain line is at least arranged. The drain valve is controlled so that the drain line is at least partially always filled with water. This makes it possible to reduce the drainage noise. In addition, the mechanical stress at high power due to dynamic fluctuations can be reduced. However, this roof water inlet is relatively expensive to manufacture.

Der Erfindung liegt die Aufgabe zugrunde, einen Dachwassereinlauf der genannten Art zu schaffen, der wesentlich kostengünstiger herstellbar ist. Der Dachwassereinlauf soll sich ebenfalls durch geringe Ablaufgeräusche und eine geringe mechanische Belastung auszeichnen.The invention has for its object to provide a roof water inlet of the type mentioned, which is much cheaper to produce. The roof water inlet should also be characterized by low drainage noise and a low mechanical load.

Die Aufgabe ist bei einem gattungsgemässen Dachwassereinlauf gemäss Anspruch 1 gelöst. Durch die Anordnung des Ventils in der Wassersammelmulde kann ein regulierter Ablauf auch ohne einen Füllstandssensor erreicht werden. Das Ventil öffnet im Wesentlichen proportional zum Anfall des Regenwassers, so dass ein Ansaugen von Luft und damit die Bildung von Turbulenzen im Ablaufrohr weitgehend vermieden werden kann.The problem is solved in a generic roof water inlet according to claim 1. The arrangement of the valve in the water collection well, a regulated flow can be achieved without a level sensor. The valve opens substantially proportionally to the attack of rainwater, so that suction of air and thus the formation of turbulence in the drainage pipe can be largely avoided.

Der Dachwassereinlauf kann besonders kostengünstig hergestellt werden, da das Ventil als Schwimmerventil ausgebildet ist.The roof water inlet can be made particularly inexpensive, since the valve is designed as a float valve.

Vorzugsweise ist der Dachwassereinlauf so ausgebildet, dass sich das Ventil nach dem Erreichen einer vorbestimmten Wasserhöhe in der Wassersammelmulde selbsttätig öffnet. Nach dem Öffnen öffnet das Ventil vorzugsweise kontinuierlich entsprechend dem Wasseranfall. Mit ansteigender Wasserhöhe wird die Ablauföffnung entsprechend grösser und dadurch kann eine optimale Vollfüllung erreicht werden. Das Ventil ist so eingestellt, dass beispielsweise ab einer Leistung von 4 l/Sek. eine Vollfüllung gewährleistet ist. Bei einer kleineren Leistung erfolgt der Ablauf gravimetrisch, wobei auch hier kaum Luft angesaugt wird, da das Ventil entsprechend wenig geöffnet ist.Preferably, the roof water inlet is designed so that the valve opens automatically after reaching a predetermined height in the water collection tray. After opening, the valve preferably opens continuously according to the water attack. With increasing water level, the drain opening is correspondingly larger and thus optimal filling can be achieved. The valve is set so that, for example, from a capacity of 4 l / sec. a full filling is guaranteed. At a lower power, the process takes place gravimetrically, whereby hardly any air is sucked in here, since the valve is correspondingly less open.

Die Erfindung betrifft zudem ein Verfahren zum Betrieb eines Dachwassereinlaufes der genannten Art. Bei diesem wird das Ventil so eingestellt, dass vor einer vorbestimmten Ablaufleistung von beispielsweise 4 1/Sek. ein gravimetrischer Ablauf und über dieser Leistung ein Ablauf mit Vollfüllung erfolgt.The invention also relates to a method for operating a roof water inlet of the type mentioned. In this, the valve is adjusted so that before a predetermined drainage capacity of, for example, 4 1 / sec. a gravimetric process and over this performance a procedure with full filling takes place.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features emerge from the dependent claims, the following description and the drawings.

Show it:
FIG. 1
schematically a partial section through a roof with two inventive roof water inlets and
FIG. 2
schematically a section through an inventive roof water inlet.

Der Dachwassereinlauf 1 besitzt eine Wassersammelmulde 2, die an einem Dach 3 montiert ist. Die Wassersammelmulde 2 besitzt einen oberen Rand 5, der sich im Wesentlichen in einer Ebene 4 des Dachs 3 befindet. Im Abstand zu diesem Rand 5 weist die Wassersammelmulde 2 eine Öffnung 9 auf, welche in eine Ablaufleitung 7 führt. Auf dem Dach 3 angesammeltes Wasser gelangt über den Rand 5 in die Wassersammelmulde 2 und schliesslich durch die Öffnung 9 in die Ablaufleitung 7.The roof water inlet 1 has a water collecting trough 2, which is mounted on a roof 3. The water collecting trough 2 has an upper edge 5, which is located substantially in a plane 4 of the roof 3. At a distance from this edge 5, the water collection well 2 has an opening 9, which leads into a drain line 7. On the roof 3 accumulated water passes over the edge 5 in the water collection trough 2 and finally through the opening 9 in the drain line. 7

In der Regel sind auf dem Dach 3 mehrere solche Dachwassereinläufe 1 angeordnet, die gemäss Figur 1 mit einer im Wesentlichen horizontalen Rohrleitung 19 miteinander verbunden sind. Diese Rohrleitung 19 ist an der Unterseite des Dachs 3 mit Trägern 23 fixiert und führt in ein Fallrohr 20. Grundsätzlich können auch mehrere solche Rohrleitungen 19 und Fallrohre 20 vorgesehen sein.In general, several such roof water inlets 1 are arranged on the roof 3, according to FIG. 1 are connected to each other with a substantially horizontal pipe 19. This pipe 19 is fixed to the underside of the roof 3 with supports 23 and leads into a downpipe 20. In principle, several such pipes 19 and downpipes 20 may be provided.

Über der Wassersammelmulde 2 ist ein an sich üblicher abnehmbarer Laubfangkorb 18 angeordnet. Dieser ist für Wasser 22, jedoch nicht für grössere feste Teile, wie beispielsweise Laub, durchgängig. Ein solcher Laubfangkorb 18 ist jedoch nicht zwingend.About the water collection well 2 a per se custom removable leaf catcher basket 18 is arranged. This is for water 22, but not for larger solid parts, such as foliage, consistently. However, such a leaf catcher 18 is not mandatory.

In der Wassermulde 2 ist ein Ventil V angeordnet, das ein Gehäuse 11 aufweist, das einen nach oben ragenden Führungsteil 24 besitzt. Das untere Ende des Gehäuses ist als Flansch 12 ausgebildet, der über der Öffnung angeordnet und fest mit der Wassersammelmulde 2 verbunden ist. Der Flansch 12 besitzt wenigstens einen mittigen Durchgang 14, der mit Öffnungen 15 eines Führungsteils 24 verbunden ist. Am Führungsteil 24 ist ein Schwimmer 8 höhenverschieblich gelagert, der plattenförmig ausgebildet ist und mit einem rohrförmigen Schieber 10 am Führungsteil 24 gelagert ist. Der Schwimmer 8 ist beispielsweise hohl ausgebildet, aus einem geschäumten oder sonst wie leichten Werkstoff ausgebildet. Steigt das Wasser in der Wassersammelmulde 2 über die in Figur 2 gezeigte Anstauhöhe 16, so wird der Schwimmer 8 und mit diesem der Schieber 10 angehoben. Unterhalb dieser Anstauhöhe 16 bleibt das angestaute Wasser in der Wassersammelmulde 2 stehen. In der untersten Stellung liegt eine untere Kante 25 des Schiebers 10 auf dem Flansch 12 auf. Die Öffnungen 15 sind hierbei vom Schieber 10 abgedeckt.In the water well 2, a valve V is arranged, which has a housing 11 which has an upwardly projecting guide member 24. The lower end of the housing is formed as a flange 12 which is disposed above the opening and fixedly connected to the water collection well 2. The flange 12 has at least one central passage 14 which is connected to openings 15 of a guide member 24. On the guide member 24, a float 8 is mounted vertically displaceable, which is plate-shaped and is mounted with a tubular slider 10 on the guide member 24. The float 8 is for example hollow, formed of a foamed or otherwise light material. If the water in the water collection trough 2 rises above the in FIG. 2 shown damming height 16, the float 8 and with this the slider 10 is raised. Below this accumulation height 16, the accumulated water remains in the water collection well 2. In the lowest position, a lower edge 25 of the slider 10 rests on the flange 12. The openings 15 are covered by the slider 10.

Nachfolgend wird die Funktionsweise des Dachwassereinlaufs 1 näher erläutert.The operation of the roof water inlet 1 will be explained in more detail below.

Sammelt sich auf dem Dach 3 gemäss Figur 2 Wasser 22, so fliesst dieses über den Rand 5 in die Wassersammelmulde 2 und staut sich bis zur Anstauhöhe 16 an. Mit zunehmendem Wasseranfall steigt das Niveau des Wassers in der Wassersammelmulde 2 und hebt mit dem Schwimmer 8 den Schieber 10 an. Danach gelangt Wasser durch die teilweise freigegebenen Öffnungen 15 in den Durchgang 14 und schliesslich in die Ablaufleitung 7. Das in die Wassersammelmulde 2 einströmende Wasser wird durch den Schwimmer 8 in bekannter Weise und wie in Figur 2 gezeigt umgelenkt. Der Schwimmer 8 befindet sich wenigstens in der untersten Stellung wenigstens bereichsweise unterhalb des Randes 5 und bildet mit diesem einen umlaufenden vergleichsweise schmalen Rand R, durch den Wasser 22 abfliessen kann. Bereits in den tiefen Stellungen wird dadurch ein Ansaugen von Luft vermieden. Dadurch kann sich in der Rohrleitung 19 und im Fallrohr 20 eine geräuscharme Strömung bilden. Steigt das Wasserniveau 21 weiter an, so wird entsprechend der Schieber 10 weiter angehoben und damit die Öffnungen 15 zunehmend geöffnet. Der Durchgang durch die Öffnungen 15 wird entsprechend grösser. Dieser Vorgang erfolgt kontinuierlich bis schliesslich die untere Kante 25 des Schiebers 10 die Öffnungen 15 ganz freigibt und die Ablaufleistung somit maximal wird. Über den Öffnungen 15 befindet sich im Führungsteil 24 ein Luftraum 17, der oben mit einer Wandung 13 geschlossen ist, so dass von oben keine Luft angesaugt werden kann.Collects on the roof 3 according to FIG. 2 Water 22, so this flows over the edge 5 in the water collection tray 2 and accumulates up to the accumulation height 16 at. As the amount of water increases, the level of the water in the water collection trough 2 increases and with the float 8 raises the slider 10. Thereafter, water passes through the partially released openings 15 in the passage 14 and finally into the drain line 7. The water flowing into the water collection tray 2 is water by the float 8 in a known manner and as in FIG. 2 shown deflected. The float 8 is at least in the lowest position at least partially below the edge 5 and forms with this a circumferential comparatively narrow edge R, can flow through the water 22. Already in the deep positions, this prevents the intake of air. This can form a low-noise flow in the pipe 19 and the downpipe 20. If the water level 21 continues to increase, so does the slider 10 further raised and thus the openings 15 increasingly open. The passage through the openings 15 is correspondingly larger. This process takes place continuously until finally the lower edge 25 of the slider 10 completely clears the openings 15 and thus the drainage capacity becomes maximum. Above the openings 15 is located in the guide member 24, an air space 17 which is closed at the top with a wall 13, so that no air can be sucked from above.

Sinkt das Wasserniveau 21 bei geöffnetem Ventil V, so fällt entsprechend kontinuierlich der Schieber 10 bis schliesslich die Öffnungen 15 geschlossen sind. Die Ablauföffnung wird somit entsprechend kontinuierlich verkleinert.If the water level 21 drops when the valve V is open, the slide 10 accordingly drops continuously until finally the openings 15 are closed. The drain opening is thus continuously reduced accordingly.

Durch die Selbstregulierung des Abflusses verringern sich von Anfang an die Ablaufgeräusche, die durch Schwingungen und durch mitgenommene Luft verursacht werden. Durch die Dämpfung der Schwingungen wird auch die mechanische Belastung im Rohrleitungssystem vermindert. Das Ventil V kann als Schwimmerventil mechanisch sehr einfach und trotzdem funktionssicher ausgebildet werden. Ein Füllstandssensor oder ähnliche Messmittel sind nicht erforderlich.The self-regulation of the drain reduces from the beginning the drainage noise caused by vibrations and entrained air. By damping the vibrations and the mechanical stress in the piping system is reduced. The valve V can be designed as a float valve mechanically very simple and still reliable. A level sensor or similar measuring means are not required.
