Description

Opfindelsen angår en vakuumtoiletanordning for mobile enheder,såsom tog og busser omfattende mindst én toiletstol, midlerfor frembringelse af et vakuum, en opsamlingsbeholder, lednin¬ger med ventiler til at transportere materiale fra toiletsto¬len til opsamlingsbeholderen ved hjælp af det nævnte vakuum,en ventrikel, som er indkoblet i ledningen for opsamlingsbe¬holderen og organer for tilførsel af skyllevæske til toilet¬stolen, hvorhos organerne til frembringelse af et vakuum iventriklen og i ledningerne består af en pneumatisk ejektorsluttet til en trykluftbeholder.The invention relates to a vacuum toilet device for mobile units, such as trains and buses comprising at least one toilet seat, means for generating a vacuum, a collecting container, conduits with valves for transporting material from the toilet seat to the collecting container by means of said vacuum, a ventricle which is connected in the conduit of the collection vessel and means for supplying flushing fluid to the toilet seat, the means for producing a vacuum inlet and in the conduits consisting of a pneumatic ejector connected to a compressed air vessel.

En sådan vakuumtoiletanordning kendes f.éks. fra svensk frem¬læggelsesskrift nr. 421.769. Hvis en af ventilerne går i styk¬ker, vil der imidlertid kunne løbe vand ud over toiletkummenog ud på gulvet.Such a vacuum toilet device is known, for example. from Swedish Petition No. 421,769. However, if one of the valves breaks down, water may flow over the toilet bowl and out onto the floor.

Formålet med opfindelsen er at anvise, hvorledes man elimine¬rer denne risiko, og dette formål er ifølge opfindelsen opnåetved hjælp af en hævertbrydende anordning, der kan tilføre lufttil den rørstrækning, der står i forbindelse med skyllevæske-tanken. Derved undgås vandskader i tilfælde af, at ventilernei skyl lesystemet skulle blive utætte, idet ansøgeren har er¬kendt, at udstrømningerne i forbindelse med de hidtidige an¬ordninger var en følge af hævertvirkningen.The object of the invention is to disclose how to eliminate this risk and this object is achieved according to the invention by means of an adhesive-breaking device which can supply air to the pipe line which is connected with the rinse liquid tank. This prevents water damage in the event that the valves do not flush the leakage system, as the applicant acknowledges that the outflows in connection with the previous devices were a consequence of the siphon effect.

Opfindelsen skal nærmere forklares i det følgende under hen¬visning til tegningen, hvor fig. 1 viser et vakuumtoiletsystem ifølge opfindelsen omfat¬tende mindst én toiletstol og en fækalietank, fig. 2 en ventrikelbeholder indskudt imellem toiletstolen ogfækal i etanken, fig. 3 en hævertbrydende anordning, der er indskudt i rør¬strækningen fra skyllevæsketanken, fig. 4 en fyldeanordning i forbindelse med den i fig. 3 visterørstrækning og fig. 5 det pågældende styresystem.The invention will be explained in more detail below with reference to the drawing, in which fig. 1 shows a vacuum toilet system according to the invention comprising at least one toilet seat and a faecal tank; FIG. 2 shows a ventricular container inserted between the toilet seat and fecal in the tank; FIG. 3 shows an adhesive-breaking device inserted into the pipe section of the rinsing tank; FIG. 4 shows a filling device in connection with the one shown in FIG. 3; 5 the operating system concerned.

Det i fig. 1 viste vakuumtoiletsystem for mobile enheder, så¬som tog eller busser, omfatter mindst én toiletstol 22, midlerfor frembringelse af et vakuum, en opsamlingsbeholder, lednin¬ger med ventiler til at transportere materiale fra toiletsto¬len 22 til opsamlingsbeholderen ved hjælp af det nævnte vaku¬um, og en ventrikel 19, som er indkoblet i ledningen for op¬samlingsbeholderen. Endvidere er der indrettet organer fortilførsel af skyllevæske til toiletstolen 22. Organerne tilfrembringelse af et vakuum i ventriklen 19 og i ledningerneudgøres af en ejektor 11 sluttet til en trykluftbeholder.The FIG. 1, the vacuum toilet system of mobile units, such as trains or buses, comprises at least one toilet seat 22, means for generating a vacuum, a collection container, conduits with valves for transporting material from the toilet seat 22 to the collection container by means of said vacuum, and a ventricle 19 which is plugged into the conduit of the collection vessel. Further, means are provided for supplying flushing fluid to the toilet chair 22. The means for generating a vacuum in the ventricle 19 and in the conduits are constituted by an ejector 11 connected to a compressed air container.

I forbindelse med ventriklen er der indrettet to slangeventi¬ler 17 og 18. To følere 25 overvåger niveauet i fækalietanken23, der tømmes ved hjælp af en slamsuger eller lignende.In connection with the ventricle, two hose valves 17 and 18. Two sensors 25 monitor the level in the fecal tank 23 which is emptied by means of a mud cleaner or the like.

Toiletsystemet aktiveres ved at påvirke en skyl leknap 26. Såsnart aktiveringen er sket, opbygges det nødvendige vakuum iventriklen 19. Systemet skyller derefter og transporterer fæ¬kalier med videre ti l fækalietanken 23. Den samlede skyl lecyk¬lus andrager ca. 15 sek.The toilet system is activated by actuating a flushing button 26. As soon as the activation has taken place, the necessary vacuum builds up the ventricle 19. The system then flushes and transports faeces with a further ten faecal tank 23. The total flushing cycle is approx. 15 sec.

Er niveauet i fækalietanken 23 steget til f.eks. 75%, indike¬res dette ved hjælp af en lampe. Nan bør derfor tømme tankenved næstkommende lejlighed. Hvis tanken skulle blive heltfuld, aktiveres en elektromagnetisk dørlås. Samtidigt tændesen rød advarselslampe, og skyl leknappert blokeres. Disse foran¬staltninger sikrer, at tanken ikke løber over.Has the level in the faecal tank 23 increased to e.g. 75%, this is indicated by a lamp. Nan should therefore empty his mind on the next occasion. If the tank becomes full, an electromagnetic door lock is activated. At the same time, the red warning light on the ignition and the flushing button is blocked. These measures ensure that the tank does not run over.

Ved aktivering af skyl leknappen 26 bliver anlæggets ventrikel19 evakueret ved hjælp af en trykluftdrevet ejektor 11 - sefig. 2 og 5. Derefter afbrydes ejektoren 11, og atmosfæretryk¬ket presser fækalier, vand med videre gennem rørsystemet ogned i ventriklen 19, hvor det midlertidigt opbevares. Ventrik¬len 19 lukkes og sættes under tryk. Derefter åbnes ventriklen19, og indholdet transporteres ved hjælp af lufttrykket viarørsystemet til fækalietanken 23. Ventriklen 19 lukkes, ogskylleforløbet afsluttes ved at toiletstolens 22 vandlås fyl¬des med vand. Toilettet er da igen i stand by position.By activating the flush button 26, the system's ventricle 19 is evacuated by means of a compressed air driven ejector 11 - sefig. 2 and 5. Then the ejector 11 is interrupted and the atmospheric pressure squeezes faeces, water, etc. through the piping system down into the ventricle 19, where it is temporarily stored. The ventricle 19 is closed and pressurized. The ventricle 19 is then opened and the contents are transported by means of the air pressure system to the faecal tank 23. The ventricle 19 is closed and the flushing process is completed by filling the toilet seat 22's water trap with water. The toilet is then in the standby position again.

Efter at en person har været på toilettet trykker han på skyl-leknappen 26, der står i forbindelse med et styreskab 21. Der¬ved startes ejektoren 1 ved at ventil nr. 1 åbnes - se fig. 5.Derved blæses der trykluft gennem ejektoren 11, hvorved deropbygges et vakuum. Dernæst aktiveres ventil nr. 2 og ventilnr. 3, og det frembragte vakuum forplanter sig derved gennemledning C og D. Ledning D er sluttet til ventriklen 19 - sefig. 2. Ventriklen 19 evakueres ca. 70%. Samtidigt suges derpå ledning C - se fig. 3. Ledning C står i forbindelse med enfyldeanordning 31, der er vist detaljeret i fig. 4. Denne fyl-deanordning 31 indeholder en gummibold 27, der bæres oppe afvandet og senere lukker fyldeanordningen 31. Undertrykket ifyldeanordningen 31 bevirker, at der suges vand ind gennem enkontraventil 28 og et vandret rørstykke. Derved fyldes det øv¬rige rørsystem med vand, indtil vandstanden er nået op tilgummibolden 27 i fyldeanordningen 31. Det lodrette rørstykkehar en diameter på 1 tomme, hvilket giver et volumen på mindst1 1. Dette vandvolumen anvendes til skylning. Når vandstandener nået til gummibolden 27, lukker denne for sugeledningen C.Bolden 27 bliver simpelthen suget fast, således at der ikkesuges mere vand ud i systemet. Rørsystemet er nu fyldt medvand. I en U-formet del af rørstystemet sidder der desuden enhævertbrydende anordning 29. Denne hævertbrydende anordning 29omfatter en kontraventil, der bevirker, at der kun kan ske enudblæsning ved ventriklens tilledning D. Den udblæste luft¬mængde reguleres ved hjælp af en drøvling, der sidder overkontraventilen.After a person has been in the toilet, he presses the flush button 26, which is connected to a control cabinet 21. The ejector 1 is then started by opening valve # 1 - see fig. 5. Thereby, compressed air is blown through the ejector 11, thereby creating a vacuum. Next, valve # 2 and valve no. 3, and the resulting vacuum propagates through passages C and D. Conduit D is connected to the ventricle 19 - sefig. 2. Ventricle 19 is evacuated for approx. 70%. At the same time, line C is then sucked - see fig. 3. Conduit C is connected to a single filling device 31, shown in detail in FIG. 4. This filling device 31 contains a rubber ball 27 which is carried up the drainage and later closes the filling device 31. The negative pressure of the filling device 31 causes water to be sucked in through the check valve 28 and a horizontal pipe piece. Thereby the other pipe system is filled with water until the water level has reached the rubber ball 27 in the filling device 31. The vertical pipe piece has a diameter of 1 inch, which gives a volume of at least 1 1. This water volume is used for rinsing. When water levels reach the rubber ball 27, it closes for the suction line C. The ball 27 is simply sucked so that more water is not sucked into the system. The piping system is now filled with water. In a U-shaped part of the pipe system there is also a self-breaking device 29. This self-breaking device 29 comprises a non-return valve, which means that a single blowout can only be effected at the ventricular supply D. the check valve.

Rørsystemet er nu blevet fyldt med vand, og ventriklen 19 erblevet evakueret. Derefter åbnes den første slangeventil (vedhjælp af ledning B) - se fig. 5. Atmosfæretrykket presser der¬efter fækalier og vand ud til ventriklen 19. Derefter afbrydesventil nr. 1 og tryklufttilførslen til ejektoren 11, og derlukkes igen for ventil nr. 2 og ventil nr. 3. Derefter aktive¬res ventil nr. 4, som står i forbindelse med ledning C. Dervedåbnes ventil nr. 4, og der tilføres trykluft til ledning C.Ledning C står i forbindelse med fyldeanordningen 31. Denneåbnes ved et tryk på ca. 3 bar ved en skylleventil 32, hvorved vandet i rørsystemet føres ud i toiletskålen 22. Samtidigt åb¬nes for ventil nr. 5, der styrer slangeventilen 18 via led¬ning B. Derved åbnes slangeventilen 18, således at vand, fæka¬lier med videre presses ind i ventriklen 19 af atmosfæretryk¬ket. Når denne proces er afsluttet, lukkes ventil nr. 4, ogderved lukkes for trykluftti lførslen til skyl leanordningen, ogder åbnes for ventil nr. 2 for aflastning af lufttrykket irørsystemet. Derved afbrydes skyl leforløbet ganske brat ikraft af at trykluft sendes ud i det fri. Dernæst aktiveresventil nr. 7, og derved blæses trykluft ud i ventriklen 19 vialedning D. Der skabes derved et overtryk i ventriklen 19. Des¬uden blæses der via den hævertbrydende anordning 29 trykluftud i det U-formede rørstykke, hvorved der sker en afbrydelseaf den hævertvirkning, der ellers kunne opstå. Der lukkes igenfor ventil nr. 7 og åbnes for ventil nr, 6, dvs. ledning A,som styrer den anden slangeventil 17, og derved opnås der ad¬gang til fækalietanken 23. Det overtryk, der er dannet i ven¬triklen 19, blæser så alt indholdet ud gennem rørsystemet tilfækalietanken 23.The piping system has now been filled with water and the ventricle 19 has been evacuated. Then open the first hose valve (using line B) - see fig. 5. The atmospheric pressure then exhausts faeces and water to the ventricle 19. Then valve # 1 and the compressed air supply to the ejector 11 are disconnected and then closed again for valve # 2 and valve # 3. Then valve # 4 is activated, which is connected to conduit C. The valve 4 is then opened, and compressed air is supplied to conduit C. Conduit C is connected to the filling device 31. This is opened at a pressure of approx. 3 bar at a flush valve 32, whereby the water in the piping system is discharged into the toilet bowl 22. At the same time, valve # 5 which controls the hose valve 18 via conduit B. is opened, thereby opening the hose valve 18 so that water, faeces with further pressed into the ventricle 19 by atmospheric pressure. When this process is completed, valve # 4 is closed, thereby closing the compressed air supply to the flushing system, and also opening valve # 2 for relieving the air pressure in the pipe system. In this way the flushing process is interrupted quite abruptly by the fact that compressed air is released into the open air. Next, valve # 7 is activated, thereby compressing compressed air into the ventricle 19 via conduit D. This creates an overpressure in the ventricle 19. In addition, via the siphon-breaking device 29 compressed air is blown into the U-shaped pipe piece, thereby causing a breakdown of the siphon effect that might otherwise occur. Valve # 7 is closed again and valve # 6 opened, ie. conduit A, which controls the second hose valve 17, thereby providing access to the fecal tank 23. The excess pressure formed in the valve 19 then blows out all the contents through the tube system the fecal tank 23.

Det her beskrevne system resulterer i en kortere cyklustid endhidtil kendt.The system described here results in a shorter cycle time than heretofore known.

Komponenterne af vakuumtoiletsystemet er koblet som vist ifig. 1. I det egentlige toiletrum placeres toiletstolen 22.Under vognbunden i nærheden af denne monteres ventriklen 19.Denne sørger for transporten af fækalier med videre fra toi-letstolen 22 til fækalietanken 23. Fækalietanken 23 kan place¬res flere steder f.eks. i eller under vognen, hvor der erbedst plads. Styringen af anlægget varetages af styreskabet21, der kan monteres et servicevenligt sted i vognen.The components of the vacuum toilet system are coupled as shown. 1. In the actual toilet room, the toilet seat 22. Position the ventricle 19. Under the trolley floor, the ventricle 19 is mounted.This ensures the transport of faeces on from the toilet seat 22 to the faecal tank 23. The faecal tank 23 can be placed in several places e.g. in or under the cart where space is needed. The control of the system is carried out by the control cabinet21, which can be mounted in a service-friendly place in the carriage.

De enkelte delenheder forbindes ved hjælp af fleksible slangerog rør. Derved dæmpes vibrationstransmissioner imellem kompo¬nenterne .The individual subunits are connected by flexible hose and tubing. This reduces vibration transmissions between the components.

Hvis togvognen er udstyret med mere end et toiletrum, kan dertilsluttes flere vakuumtoiletter til samme opsamlingstank.Derved reduceres omkostningerne både med hensyn til installa¬tion og tømning.If the trolley is equipped with more than one toilet compartment, several vacuum toilets can be connected to the same collection tank, thereby reducing the cost of both installation and emptying.
