Description

Toilettenanlage mit Unterdruckabsaugung Toilet system with vacuum suction
Die Erfindung betrifft eine Toüettenanlage mit UnterdruckabsaugungThe invention relates to a toilet system with vacuum suction
Bei herkömmlichen Toilettenanlagen wird Wasser als Transportmittel für die Fakalien genutzt. Eine Trennung des Wassers von den Fakalien erfolgt nicht. Es wird eine größere Menge von Wasser benotigt, was aus okologi- sehen und ökonomischen Gründen unerwünscht ist.In conventional toilet facilities, water is used as a means of transport for the faeces. The water is not separated from the faecal matter. A larger amount of water is required, which is undesirable for ecological and economic reasons.
Vakuumtoiletten sind seit längerem bekannt und im Einsatz. In der DE 41 36 931 AI ist eine Anlage für den Fahrzeugbau beschrieben, bei der ein Absaugbehalter evakuiert wird Danach werden mittels Ventile Leitungen geöffnet bzvv geschlossen, um mittels Druckluft das Fakal in den Sammelbehalter zu fordern. Diese Anlage hat zwar gegenüber dem bekannten Ablaufsystem gemäß DE-OS 39 32 893 den Vorteil, daß nur ein relativ kleiner Absaugbehälter unter Unterdruck gesetzt werden muß, weist aber den Nachteil auf, daß alle Rohrverbindungen und die Ventile vakuumdicht ausgeführt werden müssen und somit nur eine aufwendige technische Realisierung möglich ist.Vacuum toilets have been known for a long time and are in use. DE 41 36 931 AI describes a system for vehicle construction in which a suction container is evacuated. Lines are then opened or closed by means of valves in order to use compressed air to request the facal into the collecting container. This system has the advantage over the known drain system according to DE-OS 39 32 893 that only a relatively small suction container has to be placed under negative pressure, but has the disadvantage that all pipe connections and the valves have to be carried out vacuum-tight and thus only one complex technical implementation is possible.
In der DE 296 04 512 U l ist ein Verfahren beschrieben, wonach im Absaugbehalter nach jeder Absaugung ein Druckausgleich erfolgt Die Entlee- rung des Absaugbehalters in einen Fakalsammelbehalter soll drucklos erfolgen In der genannten Druckschrift sind das Verfahren und dessen Vorzuge weitläufig beschrieben, technische Losungen zur Nutzung des beschriebenen Verfahrens sind aber nicht enthalten Gemäß der Beschreibung ist der Einsatz der Anlage in größeren Gebäuden vorgesehen. Die notwendige Einzelabsaugung der Toiletten steht technisch diesem Einsatzgebiet entgegen. Es wird weiterhin ein Widerspruch darin gesehen, einerseits eine permanente Geruchsabsaugung zu realisieren und andererseits nach jedem Absaugvorgang den Absaugbehälter nach Druckausgleich zu entleeren.In DE 296 04 512 U l, a method is described, which is carried out in Absaugbehalter to j Eder suction pressure equalization The emptying tion of Absaugbehalters in a Fakalsammelbehalter is to be depressurized in the publication mentioned, the method and its merits are widely described, technical solutions to use the described method are not included. According to the description, the Use of the system in larger buildings. The necessary individual suction of the toilets is technically opposed to this area of application. There is also a contradiction in realizing a permanent odor extraction on the one hand and emptying the suction container after pressure equalization after each extraction process.
Der Erfindung liegt die Aufgabe zugrunde, mit einfachen Mitteln eine Umrüstung eines konventionellen Toilettenbeckens auf Absaugung zu ermöglichen.The object of the invention is to enable a conventional toilet bowl to be converted to suction with simple means.
Diese Aufgabe wird mit den im Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in claim 1.
Dadurch, daß ein konventionelles Toilettenbecken, in der Regel ein Tiefspülbecken, mit einem an eine Absaugvorrichtung angeschlossenen Einsatz versehen wird, kann eine Umrüstung auf Absaugung mit dem Vorteil der Wassereinsparung vorgenommen werden. Die Umrüstung kann vorzugsweise bei vorhandenen Toilettenbecken vorgenommen werden, es ist aber auch möglich, bei neu zu installierenden Toilettenanlagen umzurüsten.The fact that a conventional toilet bowl, usually a sink, is provided with an insert connected to a suction device, can be converted to suction with the advantage of saving water. The retrofitting can preferably be carried out with existing toilet bowls, but it is also possible to retrofit with newly installed toilet facilities.
An das Absaugaggregat können auch zwei oder mehr Toilettenbecken angeschlossen werden, es wird aber immer jedes Toilettenbecken einzeln abgesaugt. Deswegen kann das Volumen des Absaugaggregats klein gehalten werden.Two or more toilet bowls can also be connected to the suction unit, but each toilet bowl is always suctioned off individually. Therefore, the volume of the suction unit can be kept small.
Da für das Absaugaggregat zum Betrieb ein Gebläse und auch für die Steuerung ein Elektroanschluß vorhanden sein muß, bietet es sich an, das Toilettenbecken mit Komforteinrichtungen wie Beheizung, Beleuchtung, Beschallung mit Musik und dergl. zu versehen. Der Einsatz der erfindungsgemäß ausgebildeten Toilettenanlage erfolgt vorzugsweise in Fahrzeugen, z.B. in Wohnmobilen und Wohnanhängern, er ist aber auch in stationären Einrichtungen, also z.B. in Ein- und Zweifamilienhäusern, möglich.Since there must be a fan for the suction unit for operation and also an electrical connection for the control, it makes sense to provide the toilet bowl with comfort facilities such as heating, lighting, sound with music and the like. The toilet system designed according to the invention is preferably used in vehicles, for example in mobile homes and caravans, but it is also possible in stationary facilities, for example in one- and two-family houses.
Ein besonderer Vorteil der erfindungsgemäß ausgebildeten Anlage besteht darin, daß weder die Rohrverbindungen noch die Ventile vakuumdicht ausgeführt sein müssen.A particular advantage of the system designed according to the invention is that neither the pipe connections nor the valves have to be vacuum-tight.
Weitere vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.
Insbesondere ist von Vorteil, wenn das Absaugaggregat auch für eine Ge- ruchabsaugung eingesetzt wird, wobei die für die Fäkalabsaugung notwendige Absaugleitung auch für die Geruchabsaugung verwendet wird.It is particularly advantageous if the suction unit is also used for odor extraction, the suction line required for fecal extraction also being used for odor extraction.
Die Erfindung wird im folgenden anhand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläutert. Es zeigt:The invention is explained in more detail below on the basis of exemplary embodiments schematically illustrated in the drawing. It shows:

Die Fig. 1 zeigt ein konventionelles Toilettenbecken 10, das als Tietspul- becken ausgebildet ist. In das Toilettenbecken 10 ist zur Umrüstung auf Absaugung ein Einsatz l eingebracht, der in seinen Abmessungen an die Abmessungen des Toilettenbeckens 10 angepaßt ist. Der Einsatz 1 , der mit einer Antihaftbeschichtung versehen ist, hegt über Flansche auf dem oberen Rand des Toilettenbeckens 10 auf.Cut; 7 shows the hose used for the hose valve arranged at the lower end of the suction unit in cross-section; Fig. 8 shows the object shown in Fig. 7 in a side view. 1 shows a conventional toilet bowl 10, which is designed as a wash basin. In the toilet bowl 10 an insert l is introduced for conversion to suction, the dimensions of which are adapted to the dimensions of the toilet bowl 10. The insert 1, which is provided with a non-stick coating, rests on flanges on the upper edge of the toilet bowl 10.
Nahe dem oberen Rand des Einsatzes befinden sich Spuldusen 7, die über eine Spύlleitung 2 an ein Spülventil 3 angeschlossen sind. Das Spülventil 3 wird mit Druckwasser beaufschlagt. Das Druckwasser stammt bei einer Verwendung in einem Gebäude aus dem Hauswassernetz, ansonsten aus einem Wasserbehälter mit angeschlossenem Druckerzeuger.Near the upper edge of the insert there are rinsers 7 which are connected to a rinsing valve 3 via a rinsing line 2. The flushing valve 3 is pressurized with pressurized water. When used in a building, the pressurized water comes from the domestic water network, otherwise from a water tank with a connected pressure generator.
Am unteren Ende des Einsatzes 1 befindet sich ein Geruchverschluß 6, der hier in der Form des für diesen Zweck üblichen Siphons ausgebildet ist. Das absaugseitige Ende des Siphons ist an eine Absaugleitung 6 angeschlossen, deren anderes Ende mit einem noch zu beschreibenden AbsaugaggregatAt the lower end of the insert 1 there is an odor trap 6, which is designed here in the form of the siphon which is customary for this purpose. The suction-side end of the siphon is connected to a suction line 6, the other end of which is to be described with a suction unit
14 verbunden ist (Fig. 2). Das Absaugaggregat 14 weist einen Bodenablaß14 is connected (Fig. 2). The suction unit 14 has a floor drain
15 auf, über den das Absaugaggregat 14 in einen Sammelbehälter 12 ent- leerbar ist.15, via which the suction unit 14 can be emptied into a collecting container 12.
Das umgerüstete Toilettenbecken 10 ist auch mit Mitteln zur Geruchabsau- gung versehen. Die Geruchabsaugung erfolgt über eine Geruchabsaugleitung 9, deren eines Ende an das obere Ende des Einsatzes 1 und deren anderes Ende an die Absaugleitung des Geruchverschlusses 6 angeschlossen ist.The retrofitted toilet bowl 10 is also provided with means for odor extraction. The odor extraction takes place via an odor extraction line 9, one end of which is connected to the upper end of the insert 1 and the other end of which is connected to the extraction line of the odor trap 6.
Die verschiedenen Aggregate und Ventile werden durch eine Steuerung 13 betätigt, die durch Bewegen eines Betatigungselements 8 in Funktion tritt. In Fig 2 ist dargestellt, daß zwei Toilettenbecken 10 an ein Absaugaggregat 14 angeschlossen sind Für diese Konstellation ist die Absaugleitung 5 über ein Stellventil 1 1 in der Weise verzweigt, daß immer nur ein Toilettenbek- ken 10 evakuiert wirdThe various units and valves are actuated by a controller 13, which comes into operation by moving an actuating element 8. 2 shows that two toilet bowls 10 are connected to a suction unit 14. For this constellation, the suction line 5 is branched via a control valve 11 in such a way that only one toilet bowl 10 is ever evacuated
In Fig. 3 ist schematisch der Aufbau eines Absaugaggregats 14 dargestellt. Dieses weist einen Absaugbehalter 16 auf, an dessen oberem Ende sich ein Geblase 17 befindet, dessen Saugseite mit dem Absaugbehälter 16 verbunden ist, in den die Absaugleitung 5 einmundet.In Fig. 3, the structure of a suction unit 14 is shown schematically. This has a suction container 16, at the upper end of which there is a blower 17, the suction side of which is connected to the suction container 16, into which the suction line 5 merges.
Am unteren Ende des Absaugbehalters 16 befindet sich ein Bodenablaß 15, der durch ein Schlauchventil 19 verschließbar istAt the lower end of the suction container 16 there is a floor drain 15 which can be closed by a hose valve 19
Das Schließen des Schlauchventils 19 erfolgt in der Weise, daß die Druck- seite des Geblases 17 an zwei Abluftleitungen 18 angeschlossen ist, deren Mundungen einander gegenüberliegend radial auf den das Schlauchventil 19 bildenden Schlauch 23 gerichtet sind Der Schlauch 23 ist in radialer Richtung leicht verformbar und wird durch den aus den Abluftleitungen 18 austretenden Abluftstrom in Verbindung mit dem im Absaugbehalter 16 auftretenden Unterdruck zusammengedruckt, so daß das Schlauchventil 19 geschlossen wird. Der Bodenablaß 15 ist normalerweise geöffnetThe hose valve 19 is closed in such a way that the pressure side of the blower 17 is connected to two exhaust air lines 18, the mouths of which are directed radially opposite one another onto the hose 23 forming the hose valve 19. The hose 23 is easily deformable in the radial direction and is compressed by the exhaust air flow emerging from the exhaust air lines 18 in connection with the negative pressure occurring in the suction container 16, so that the hose valve 19 is closed. The floor drain 15 is normally open
In Fig 4 ist ein Ventil 4 dargestellt, welches dafür sorgt, daß bei geringer Saugleistung des Geblases 17 eine Verbindung zwischen der Absaugleitung 5 und der Geruchabsaugleitung 9 hergestellt wird, wahrend dieses Ventil 4 bei st rkerer Saugleistung, nam ch beim Absaugen der Toiletteninhaltstoffe, geschlossen wird Zu diesem Zweck ist in einem Gehäuse 21 ein Verschluß- korper 22 angeordnet, der bei geringer Saugleistung etwas angehoben wird und dadurch die Geruchabsaugleitung 9 an die Absaugleitung 5 anschließt, wahrend bei stärkerer Saugleistung der Verschlußkoφer 22 in seine obere Schließposition gelangt, so daß wahrend des Evakuierens des Einsatzes l keine Geruchabsaugung stattfindet.In Fig. 4, a valve 4 is shown, which ensures that at low suction power of the blower 17, a connection between the suction line 5 and the odor suction line 9 is made, while this valve 4 is closed with stronger suction power, namely when suctioning the toilet contents For this purpose, a closure body 22 is arranged in a housing 21, which is raised somewhat when the suction power is low and thereby connects the odor suction line 9 to the suction line 5, while when the suction power is stronger the closure body 22 is in its upper one Closing position arrives so that no odor extraction takes place during the evacuation of the insert l.
In den Fig. 5 und 6 ist ein mechanisch wirkender Geruchverschluß darge- stellt, der alternativ zu einem Siphon eingesetzt werden kann. Dieser Geruchverschluß weist ein Gehäuse 24 auf, das in die Absaugleitung 5 zwischengeschaltet ist und ferner an die Geruchabsaugleitung 9 angeschlossen ist. Durch Drehen eines mit einer Ausfräsung 27 versehenen Drehschiebers 25 kann wahlweise die Absaugleitung 5 freigegeben werden oder der ab- saugseitige Abschnitt der Absaugleitung 5 wirkungsmäßig mit der Geruchabsaugleitung 9 verbunden werden. In einer dritten Stellung wird sowohl die Absaugleitung 5 als auch die Geruchabsaugleitung 9 geschlossen. Der Drehschieber 25 ist im Gehäuse 24 gelagert und kann durch ein Stellglied bet tigt werden, wobei diese Betätigung durch die Steuerung 13 veranlaßt wird.5 and 6 show a mechanically acting odor trap which can be used as an alternative to a siphon. This odor trap has a housing 24 which is interposed in the suction line 5 and is also connected to the odor suction line 9. By turning a rotary slide valve 25 provided with a cutout 27, the suction line 5 can optionally be released or the section of the suction line 5 on the suction side can be operatively connected to the odor suction line 9. In a third position, both the suction line 5 and the odor suction line 9 are closed. The rotary valve 25 is mounted in the housing 24 and can be actuated by an actuator, this actuation being caused by the controller 13.
Gemäß den Fig. 7 und 8 ist der im Bodenablaß 15 angeordnete, das Schlauchventil 19 bildende Schlauch 23 zur Langsversteifung mit Versteifungsrippen 26 versehen. Durch diese Rippen wird die gewünschte leichte Verformbarkeit in radialer Richtung nicht beeinträchtigt.7 and 8, the hose 23 arranged in the floor drain 15 and forming the hose valve 19 is provided with stiffening ribs 26 for longitudinal stiffening. The desired easy deformability in the radial direction is not impaired by these ribs.
Die durch die Steuerung 13 bewerkstelligte Funktionsweise der vorstehend beschriebenen Vorrichtung ist folgende:The functioning of the device described above, which is accomplished by the controller 13, is as follows:
Bei Betätigung des Betatigungselements 8 saugt das Geblase 17 Luft aus dem Absaugbehalter 16 und der Absaugleitung 5. Der dabei entstehende Abluftstrom wird über die Abluftleitungen 18 in radialer Richtung von zwei Seiten auf das Schlauchventil 19 geleitet. Dieser Abluftstrom und der Unterdruck durch das Absaugen der Luft aus dem Absaugbehalter 16 bewirken ein Schließen des Schlauchventils 19. Es erfolgt nun die Geruchabsaugung bei verminderter Drehzahl des Gebläses 17. Die verringerte Drehzahl kann durch ein Bauelement in der Steuerung 13 verändert und der Länge der Absaugleitung 5 und der Anlagenanordnung angepaßt werden. Nach einer in der Steuerung 13 programmierten Zeit oder nach nochmaligem Betätigen des Betätigungselements 8 wird die Drehzahl des Gebläses 17 mit einer Sanftanlaufschaltung auf die volle Drehzahl erhöht. Es wird nun der Inhalt des Einsatzes 1 in den Absaugbehalter 16 gesaugt, nachdem das Ventil 4 geschlossen wurde. Der Gasabscheider 20 verhindert, daß das Absauggut in das Gebläse 17 gelangt. Der Steuerimpuls zur Erhöhung der Drehzahl des Gebläses 17 bewirkt gleichzeitig eine Öffnung des Spülventils 3 zur Spülung des Einsatzes 1. Das Wasser aus dem vorhandenen Druckwassernetz gelangt durch das Spülventil 3 in die Spüldüsen 7 und wird durch diese in den Einsatz 1 gesprüht, um diesen zu reinigen. Die Dauer des Absaugvorgangs ist durch die Steuerung 13 geregelt und kann bei der Montage dem Anlagenaufbau angepaßt werden. Die Dauer des Spülvorgangs ist ebenfalls durch die Steuerung 13 geregelt. Nach dem Abschalten des Gebläses 17 bleibt das Druckspülventil noch eine kurze Zeit geöffnet, um zu erreichen, daß der Geruchverschluß 6, beispielsweise der Siphon, wieder mit Wasser gefüllt ist. Das nach der Absaugung im Absaugbehalter 16 befindliche Absauggut kann nun nach dem selbständigen Öffnen des Schlauchventils 19 im Bodenablaß 15 in einen Sammelbehälter 12 oder in die Kanalisation abfließen. When the actuating element 8 is actuated, the blower 17 sucks air out of the suction container 16 and the suction line 5. The resulting exhaust air flow is directed in a radial direction via the exhaust air lines 18 to the hose valve 19 from two sides. This exhaust air flow and the negative pressure due to the suction of the air from the suction container 16 cause the hose valve 19 to close. The odor extraction now takes place at a reduced speed of the fan 17. The reduced speed can be changed by a component in the controller 13 and adapted to the length of the suction line 5 and the system arrangement. After a time programmed in the controller 13 or after actuating the actuating element 8 again, the speed of the fan 17 is increased to the full speed with a soft start circuit. The contents of the insert 1 are now sucked into the suction container 16 after the valve 4 has been closed. The gas separator 20 prevents the suction material from getting into the blower 17. The control pulse to increase the speed of the fan 17 also causes the flushing valve 3 to be opened for flushing the insert 1. The water from the existing pressurized water network passes through the flushing valve 3 into the flushing nozzles 7 and is sprayed through this into the insert 1 in order to close it clean. The duration of the suction process is regulated by the controller 13 and can be adapted to the system structure during assembly. The duration of the rinsing process is also regulated by the controller 13. After the fan 17 has been switched off, the pressure-flushing valve remains open for a short time in order to ensure that the odor trap 6, for example the siphon, is again filled with water. The suction material located in the suction container 16 after the suction can now flow into a collecting container 12 or into the sewage system after the hose valve 19 has automatically opened in the floor drain 15.
