Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Anschließen einer Regenwasser-Zisterne an die häusliche Installation um diese mittels eines sog. Hauswasserwerkes mit Regenwasser zu versorgen (z. B. Toiletten, Waschmaschinen).The invention relates to a device for connecting a rainwater cistern to the domestic installation to this by means of a so-called house waterworks with rainwater supply (e.g. toilets, washing machines).
Um für den Fall eines niederschlagsarmen Zeitraums trotzdem die angeschlossenen Wasserverbraucher mit Wasser versorgen zu können sind Installationen bekannt, die die in diesem Fall die Zufuhr von Trinkwasser regeln. So dürfen nach der Trinkwasserverordnung und DIN 1988 Trinkwasserleitungen nicht mit Wasserleitungen verbunden sein, die nicht Trinkwasser (also z. B. Regenwasser) führen.In order to be able to use the connected ones in the event of a low-precipitation period Installations are known to be able to supply water consumers with water regulate the supply of drinking water in this case. So according to the Drinking Water Ordinance and DIN 1988 drinking water pipes should not be connected to water pipes that are not Lead drinking water (e.g. rainwater).
Dieser Vorschrift wird dadurch entsprochen, daß bei unterschreiten eines Minimalwasserstandes die Frischwasserzuführung durch einen freien Zulauf, der unter keinen Umständen mit Nicht-Trinkwasser in Kontakt kommen darf, vorgenommen wird. Um dies zu bewerkstelligen sind von den ausführenden Handwerkern folgende Komponenten innerhalb der Zisterne zu installieren: Magnetventil, Schwimmerschalter für Trockenlaufschutz und Minimalwasserstand (die Schwimmerschalter sprechen durch entsprechende Fixierung an der Zisterne auf die überwachten Wasserstände an, d. h. die Einstellung ist mehr als problematisch), Saugrohranschluß mit Rückschlagventil für das anzuschließende Hauswasserwerk und gfls. einen Sensor zur Anzeige des Zisterneninhalts.This regulation is complied with by falling below a minimum water level the fresh water supply through a free inlet, which under no Circumstances may come into contact with non-drinking water. In order to accomplish this, the following components are required by the executing craftsmen To be installed inside the cistern: solenoid valve, float switch for dry running protection and minimum water level (the float switches respond by appropriate fixation the cistern to the monitored water levels, d. H. the setting is more than problematic), intake manifold connection with check valve for the to be connected Domestic waterworks and gfls. a sensor to display the contents of the cistern.
Trotz des offensichtlichen Installationsaufwandes bleibt jedoch ein insbesondere für größere Zisternen wesentliches Problem ungelöst: bei unterschreiten des Minimalwasserstandes müssen aufgrund der im allgemeinen großen Fläche (typisch: 3,5 qm) des Zisternenbodens große Frischwassermengen (350 Liter/10 cm Wasserstand) zugeführt werden, ehe der Zulauf wieder gestoppt werden kann. Dieses zugeführte Trinkwasser wird mit dem in der Zisterne noch befindlichen Regenwasser vermischt. Dieser Qualitätsminderung kommt deshalb auch hohe Bedeutung zu, daß durch den freien Zulauf des Trinkwassers in die Zisterne auf dem Zisternenboden befindliche Schlammablagerungen (falls nicht mit einer wie unter P 42 02 245.2 beschriebenen Vorrichtung nur gereinigtes Regenwasser in die Zisterne gelangt) aufgewühlt werden. Diese Vermischung von Trinkwasser und Regenwasser mit Schlammablagerungen bedeutet, daß für den Fall einer notwendigen Frischwasserzufuhr die Wasserqualität an den Entnahmestellen abnimmt.Despite the obvious installation effort, one remains, especially for larger ones Cisterns essential problem unsolved: if the minimum water level falls below due to the generally large area (typically: 3.5 square meters) of the cistern floor Fresh water quantities (350 liters / 10 cm water level) are added before the inlet again can be stopped. This supplied drinking water is still in the cistern rainwater is mixed. This reduction in quality also comes with high Significance that through the free inflow of drinking water into the cistern on the Mud deposits located in the cistern floor (if not with one as below P 42 02 245.2 described device only cleaned rainwater enters the cistern) be churned up. This mixing of drinking water and rainwater with Sludge deposits means that in the event of a necessary fresh water supply Water quality at the tapping points decreases.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, die vorstehend genannten Nachteile zu beseitigen, insbesondere eine Vorrichtung zu schaffen, mit derThe present invention is therefore based on the object, the aforementioned To eliminate disadvantages, in particular to create a device with which
- - das Anschließen von Zisternen vereinfacht wird,- the connection of cisterns is simplified,
- - mit der so wenig Trinkwasser wie möglich aber soviel wie notwendig der Zisterne zugeführt wird und- with as little drinking water as possible but as much as necessary the cistern is fed and
- - mit der im Falle einer Trinkwasserzufuhr in die Zisterne die Wasserqualität an den Entnahmestellen beständig zunimmt.- With which in the case of a drinking water supply in the cistern the water quality to the Tapping points is constantly increasing.
Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung wie in Bild 1 dargestellt insbesondere dadurch erreicht,According to the invention, this object is achieved in particular by a device as shown in Figure 1,
- - daß sämtliche für den Anschluß der Zisterne benötigten Anschlüsse im Zisternen-Dom liegen (das ist der Bereich, der nicht der Wasserspeicherung dient), innerhalb des eigentlichen Speicherraumes also keine Installationsmaßnahmen erforderlich sind- That all connections required for the connection of the cistern in the cistern cathedral lie (this is the area that is not used for water storage) within the actual storage space so no installation measures are required
- - daß die auf dem Zisternenboden lose liegende Einheit folgende Komponenten zusammenfaßt: Sensor für Tankinhaltsmessung (4), Schwimmerschalter für Frischwasserzulaufs-Niveau (1), Schwimmerschalter für Trockenlaufschutz-Niveau (2) des angeschlossenen Hauswasserwerkes, Rückflußverhinderer und Siebkorb (5) für die Wasserentnahme aus der Zisterne, Entnahmepuffer (6),- That the unit lying loosely on the bottom of the cistern combines the following components: sensor for tank content measurement ( 4 ), float switch for fresh water supply level ( 1 ), float switch for dry running protection level ( 2 ) of the connected domestic waterworks, backflow preventer and strainer basket ( 5 ) for water withdrawal from the cistern, removal buffer ( 6 ),
- - daß das über die Trinkwasserleitung (7) zugeführte Wasser über eine freie Strecke (12) in den sog. Entnahmepuffer (6) geleitet wird, aus dem die Entnahmeleitung (8) entweder Zisternenwasser oder das zugeführte Trinkwasser entnimmt, so daß das zugeführte Trinkwasser also nicht mit dem Restwasser in der Zisterne vermischt wird- That the water supplied via the drinking water line ( 7 ) is passed over a free path ( 12 ) into the so-called extraction buffer ( 6 ), from which the extraction line ( 8 ) either takes cistern water or the drinking water supplied, so that the drinking water supplied is not mixed with the residual water in the cistern
- - daß die lose auf dem Zisternenboden liegende Einheit per Schlauch- (8, 13) und Kabelverbindungen (14) in Zisternen bis zu einer festzulegenden Maximalhöhe ohne Installationsaufwand durch Absenken in die Zisterne eingebracht werden kann,- That the unit lying loosely on the bottom of the cistern can be inserted into the cistern by lowering into the cistern by hose ( 8 , 13 ) and cable connections ( 14 ) in cisterns up to a maximum height to be determined,
- - daß die Frischwasserzufuhr so gesteuert wird, daß auch bei hohem Leitungsdruck (öffentliches Netz) und kleinen Durchfluß-Öffnungen der verwendeten Magnetventile (15, 16) zugeführtes Frischwasser nur in den Entnahmepuffer (6) gelangt, die zugeführte Trinkwassermenge also minimiert wird.- That the fresh water supply is controlled so that even with high line pressure (public network) and small flow openings of the solenoid valves ( 15 , 16 ) supplied fresh water only gets into the removal buffer ( 6 ), the amount of drinking water supplied is thus minimized.
Insbesondere kann durch eine so komplettierte Einheit, bei der der Installateur lediglich die aus der Zisterne herauszuführenden Anschlüsse (7, 8, 9, 10, 11) versorgen muß, den Vorschriften der Trinkwasserverordnung sicher Rechnung getragen werden. Folgende Anschlüsse müssen vom Installateur versorgt werden: Frischwasser-Anschluß (7), Entnahmeleitung (8), Stromversorgung (9), Tankanzeigen-Anschluß (10) und Pumpenschaltkontakt (11).In particular, such a completed unit, in which the installer only has to supply the connections ( 7 , 8 , 9 , 10 , 11 ) to be led out of the cistern, can safely comply with the provisions of the Drinking Water Ordinance. The installer must supply the following connections: fresh water connection ( 7 ), extraction line ( 8 ), power supply ( 9 ), fuel gauge connection ( 10 ) and pump switch contact ( 11 ).
Das Hauswasserwerk saugt über die Entnahmeleitung (8) Wasser aus dem Entnahmepuffer an, der wiederum Zisternenwasser über den Rückflußverhinderer mit Siebkorb (5) aus der Zisterne ansaugt; wichtig ist, daß hierbei das Magnetventil (16) geschlossen ist.The domestic waterworks sucks water from the extraction buffer via the extraction line ( 8 ), which in turn sucks cistern water out of the cistern via the backflow preventer with strainer basket ( 5 ); it is important that the solenoid valve ( 16 ) is closed.
- - Magnetventil (15) öffnet, wodurch Frischwasser in den Zulaufpuffer (6) fließt,- solenoid valve ( 15 ) opens, causing fresh water to flow into the inlet buffer ( 6 ),
- - Magnetventil (16) öffnet, wodurch sich der Zulauf-Puffer (17) in den Entnahmepuffer (6) entleert- Solenoid valve ( 16 ) opens, whereby the inlet buffer ( 17 ) empties into the removal buffer ( 6 )
- - mittel Schwimmerschalter (3) wird das Überlaufen des Zulauf-Puffers (17) verhindert, d. h. übersteigt der Wasserstand im Zulauf-Puffer das entsprechende Niveau, so wird der Frischwasserzulauf solange unterbrochen, bis der Zulaufpuffer (17) in den Entnahmepuffer (6) entsprechend entleert wurde.- Medium float switch ( 3 ) prevents the inflow buffer ( 17 ) from overflowing, i.e. if the water level in the inflow buffer exceeds the corresponding level, the fresh water supply is interrupted until the inflow buffer ( 17 ) in the removal buffer ( 6 ) accordingly was emptied.
Wird über den Zulaufpuffer (17) im Bedarfsfall zuwenig Frischwasser dem Entnahmepuffer (6) zugeführt, so wird nach entsprechender Zeit das per Schwimmerschalter (2) überwachte Trockenlaufschutz-Niveau unterschritten, wodurch das über den Pumpenkontakt (11) angeschlossene Hauswasserwerk solange abgeschaltet wird, bis dieses Niveau wieder überschritten wird. Hauswasserwerke sind jedoch durch einen Druckkessel druckstabilisiert, d. h. kurzfristige Druckschwankungen werden von diesem ausgeglichen.If too little fresh water is supplied to the withdrawal buffer ( 6 ) via the inlet buffer ( 17 ), the dry-running protection level monitored by the float switch ( 2 ) is undershot after a corresponding time, whereby the domestic water system connected via the pump contact ( 11 ) is switched off until this level is exceeded again. However, domestic water works are pressure-stabilized by a pressure boiler, ie short-term pressure fluctuations are compensated for by this.
Bild 1 stellt die Zisternen-Anschluß-Einheit schematisch dar. Figure 1 shows the cistern connection unit schematically.
