Description
1 144645 o1 144645 d
Opfindelsen angår et klosetanlæg af den i indledningen til krav 1 angivne art, som arbejder med lille skyl-levandmængde.The invention relates to a toilet system of the type specified in the preamble of claim 1, which operates with a small amount of rinsing water.
Der har længe været et ønske om klosetter, der c kan udskylles med mindre vandvoluminer, end de der anvendesThere has long been a desire for toilets that can be flushed with smaller volumes of water than those used
DD
ved konventionelle klosetter. Disse konventionelle klosetters skyllevandvolumen er i Sverige normeret til ni liter pr. gang.by conventional toilets. The flushing volume of these conventional toilets in Sweden is standardized at nine liters per walk.
De derved fremkomne store voluminer afløbsvand kræver permanente afløbsledninger med en kapacitet, som i reglen kun g kommunale kloaknet kan fremvise.The resulting large volumes of wastewater require permanent drainage pipes with a capacity that, as a rule, only municipal sewer networks can show.
Baggrunden for ønsket om klosetter, der er udformet til små skyllevandmængder, er i nogle tilfælde, at man gerne vil undgå den ødslen med drikkeligt vand, det er at bruge dette vand til at skylle klosetter ud med. En anden og lige så tungtvejende grund til at mindske skyllevandvolumi-ner er, at de afløbsvandvoluminer, der skal behandles i rensningsanlæg, med fordel kan begrænses. Desuden findes et stigende antal huse, der har en sådan beliggenhed, at deres afløbsledninger ikke kan tilsluttes til kommunale kloaknet. For 2Q disse huse, der i reglen er fritidshuse, samt for beboelseshuse i traditionelle, spredte bebyggelser løses spildevands-problemet ved, at vandet opsamles i en tank, der, når det bliver nødvendigt, tømmes over i en bil med et slamsugningsaggregat med henblik på spildevandets landevejstransport til 2 et rensningsanlæg.The reason for the desire for toilets, which are designed for small amounts of rinsing water, is in some cases that you want to avoid the waste of drinking water that is to use this water to flush toilets out with. Another and equally weighty reason for reducing rinsing water volumes is that the effluent water volumes to be treated in treatment plants can be advantageously limited. In addition, there is an increasing number of houses that are located in such a way that their drainage pipes cannot be connected to municipal sewer networks. For 2Q these houses, which are usually holiday homes, as well as for residential houses in traditional, scattered settlements, the wastewater problem is solved by collecting the water in a tank which, when necessary, is emptied into a car with a sludge suction unit for wastewater road transport to 2 a treatment plant.
Med en sådan tanktilslutning af klosettet er det hensigtsmæssigt, at klosettets skyllevandmængde holdes lille, hvorved tankens tømningsinterval kan få en passende længde, og tømningsomkostningerne således holdes nede.With such a tank connection of the toilet, it is expedient that the flushing water quantity of the toilet is kept small, whereby the emptying interval of the tank can have a suitable length, and the emptying costs are thus kept down.
For at kunne opfylde disse krav har man anvendt 30 klosetanlæg magen til dem, der anvendes ved mobile enheder.In order to meet these requirements, 30 toilet systems similar to those used in mobile devices have been used.
Flere af disse anlæg, der arbejder med meget små skyllevandmængder, er kendte f.eks. fra skibs-, tog- og flyvemaskineklosetter. I disse kendte anlæg anvendes der store undertryk ^ til at transportere klosetaffaldet gennem ledningerne til en opsamlingstank. For at opnå disse undertryk er det nødvendigt 2 144645 o at have kostbar hjælpeudrustning i form af vakuumpumper eller ventilatorer med stor sugeevne og elektromagnetisk styrede ventiler. Adgang til elektrisk energi er således en forudsætning for, at disse systemer skal kunne fungere.Several of these plants, which work with very small volumes of rinsing water, are known e.g. from ship, train and airplane closets. In these known plants large negative pressures are used to transport the toilet waste through the pipes to a collection tank. In order to achieve these negative pressures, it is necessary to have expensive auxiliary equipment in the form of vacuum pumps or fans with high suction power and electromagnetically controlled valves. Access to electrical energy is thus a prerequisite for these systems to be able to function.
5 Der kendes klosetter, der undgår de nævnte hjælpe udstyr, og som kan skylles med vandvoluminer, der ganske vist er større end de, der forekommer ved undertryksystemerne, men dog betydeligt mindre end de vandvoluminer, der anvendes i de konventionelle systemer. Et kloset af denne art 10 er beskrevet i SE fremlæggelsesskrift nr. 366 085. I dette kloset er mindskningen i skyllevandmængden opnået ved, at kun den øverste del af skyllecisternens vandvolumen udtømmes ved skylning. Der er i øvrigt tale om et i det væsentlige konventionelt kloset. Vandlåsens dimensioner har for at 15 muliggøre vandlåsens funktion dog måttet mindskes, hvorved vandlåsens volumen mindskes fra to til én liter og dens spærrende dybde fra 50 til 35 mm. Disse foranstaltninger har i sig selv ikke været tilstrækkelige i praksis, og klosettet er da også blevet forsynet med en vakuumventil på 20 vandlåsens udløbsdel.5 Toilets are known which avoid the said auxiliary equipment and which can be flushed with volumes of water which are admittedly larger than those found in the negative pressure systems, but still considerably smaller than the volumes of water used in the conventional systems. A toilet of this kind 10 is described in SE submission specification no. 366 085. In this toilet the reduction in the amount of rinsing water is achieved by draining only the upper part of the water volume of the rinsing tank by rinsing. It is, moreover, an essentially conventional toilet. However, in order to enable the function of the water trap, the dimensions of the water trap have had to be reduced, whereby the volume of the water trap is reduced from two to one liter and its blocking depth from 50 to 35 mm. These measures have not in themselves been sufficient in practice, and the toilet has been fitted with a vacuum valve on the outlet part of the water trap.
Opfindelsen har til formål at undgå de nævnte ulemper og tilvejebringe et kloset, som er tilknyttet en enkel, gennemprøvet teknik, men som kan arbejde med en vandmængde på mindre end tre liter pr. skylning. Da de svenske 25 kommuner har pligt til at tilvejebringe permanente kloaknet, så snart det lader sig gøre, er klosettet udformet i over ensstemmelse med forskrifterne til tilslutning til sådanne kloaknet. Denne kommunale pligt er generel, men vil indenfor en overskuelig periode først og fremmest få betydning for 30 fritidshuse i tæt bebyggelse. De i denne sammenhæng vigtige forskrifter, som de kendte småtskyllende klosetter ikke opfylder, men som klosettet ifølge opfindelsen er i overensstemmelse med, er først og fremmest en spærrende vandlåsdybde på 50 mm og et vandlåsvolumen, som tillader passage for sådant 35 affald, som normalt ikke skal skylles ned i klosetter, f.eks.The object of the invention is to avoid the mentioned disadvantages and to provide a toilet which is associated with a simple, proven technique, but which can work with a water volume of less than three liters per liter. rinsing. As the Swedish 25 municipalities have a duty to provide permanent sewer networks as soon as possible, the toilet is designed in accordance with the regulations for connection to such sewer networks. This municipal duty is general, but within a foreseeable period will first and foremost have an impact on 30 holiday homes in densely populated areas. The important requirements in this connection, which the known small flushing toilets do not meet, but with which the toilet according to the invention complies, are first and foremost a blocking water trap depth of 50 mm and a water trap volume which allows passage for such waste, which normally does not should be flushed down toilets, e.g.
papirhåndklæder, hygiejnebind og bleer. Med henblik herpå skal o 3 U6665 vandlåsen indeholde så tilpas meget vand, at fordampning fra vandspejlet ikke skal sænke vandstanden så langt, at der opstår gaskommunikation fra afløbsledningen. Dette er en forskrift af stor betydning ved sporadisk anvendte fritidshu-5 se.paper towels, sanitary napkins and diapers. To this end, the water trap must contain such a sufficient amount of water that evaporation from the water table must not lower the water level to such an extent that gas communication occurs from the drain line. This is a prescription of great importance for sporadically used holiday homes.
For at opnå de opstillede mål er vandklosettet ifølge opfindelsen udformet således som det fremgår af patentkravene .In order to achieve the set goals, the water closet according to the invention is designed as it appears from the claims.
Ved hjælp af det i krav l's kendetegnende del 10 anførte opnås, at der ved skylning dannes en prop af vand i afløbsledningen, hvilken prop skaber et undertryk i den vertikale del af klosettets udløbsrør. Dette undertryk bevirker en effektiv udsugning fra klosettets vandlås. Passagen mellem genopfyldningsrøret og kanalen tjener til efter skylningen at 15 genindstille den spærrende vanddybde i vandlåsen til den foreskrevne størrelse.By means of the characterizing part 10 of claim 1, it is achieved that by rinsing a plug of water is formed in the drain line, which plug creates a negative pressure in the vertical part of the outlet pipe of the toilet. This negative pressure causes an efficient extraction from the toilet water trap. The passage between the backfill pipe and the channel serves to reset the blocking water depth in the water trap to the prescribed size after rinsing.
Ved at udforme klosetanlægget som anført i krav 2 opnås, at især det vandrette rørstykke bevirker en fordelagtig, relativ langsom udstrømning af vandet, hvilket bidrager 20 til, at den som en vandlås udformede rørbøjning fyldes med vand.By designing the toilet system as stated in claim 2, it is achieved that in particular the horizontal pipe section causes an advantageous, relatively slow outflow of the water, which contributes to the pipe bend designed as a water trap being filled with water.
Opfindelsen skal i det følgende forklares nærmere under henvisning til tegningen, på hvilken fig. 1 viser et klosetanlæg ifølge opfindelsen, 25 fig. 2 i større målestok en del af afløbsledningen fra klosetanlægget ifølge fig. 1, og fig. 3 klosettets skyllecisterne.The invention will be explained in more detail below with reference to the drawing, in which fig. 1 shows a toilet system according to the invention, fig. 2 shows on a larger scale a part of the drain line from the toilet system according to fig. 1, and FIG. 3 toilet flush cisterns.
Det på tegningen viste klosetanlæg omfatter et kloset 1 med en skyllecisterne 7. Klosettet 1 har en vandlås 30 26 og har i øvrigt en konventionel udformning. Udløbsrøret 2 fra vandlåsen 26 er gjort tilspidsende mod sin munding. Vandlåsen og udløbsrøret har form af en S-bøjning, og det har vist sig hensigtsmæssigt at lade S-bøjlen bibeholde deri sædvanligt anvendte diameter på i det væsentlige 100 mm, medens den sidste 35 del af udløbsrøret tilspidser til en diameter på i det væsentlige 65 mm. Med denne mindre diameter sparer man skyllevand samtidigt med, at diameteren er tilstrækkelig stor tilThe toilet system shown in the drawing comprises a toilet 1 with a flushing cistern 7. The toilet 1 has a water trap 30 26 and otherwise has a conventional design. The outlet pipe 2 from the water trap 26 is made tapered towards its mouth. The water trap and the outlet pipe are in the form of an S-bend, and it has been found expedient to allow the S-bracket to retain the commonly used diameter therein of substantially 100 mm, while the last part of the outlet pipe tapers to a diameter of substantially 65 mm. mm. With this smaller diameter, rinsing water is saved at the same time as the diameter is large enough

4 U4645 at tillade passage af selv det ovenfor nævnte affald, som ikke burde forekomme. Udløbsrøret 2 er tilsluttet til en under atmosfæretryk stående afløbsledning 3, som hensigtsmæssigt har nævnte reducerede diameter. Mellem udløbsrøret 2 og af-5 løbsledningen 3 er indsat et rørstykke 4 med en som en vandlås U-formet rørbøjning 8 og et gængs, vandret forløbende rør 5. En passende længde på det vandrette rør er ca. 0,5 m. Rørene 4 og 5 er sammenkoblede og koblet til udløbsrøret 2 og afløbsledningen 3 ved hjælp af med hængselbøjler forsynede 10 gummimanchetkoblinger 6. Røret 4 har en lodret indløbsdel 11 og en vandret udløbsdel 10 på hver side af den U-formede rørbøjning 8. Niveauet 24 af det i rørbøjningen 8 stående vand 9 bestemmes af den vandrette udløbsdel 10's nedre væg 27. Til forskel fra en vandlås står indløbsdelen 11 og udløbsdelen 15 10 imidlertid normalt i åben forbindelse med hinanden, idet den lavestliggende flade 25 på den U-formede rørbøjning 8's øvre væg ligger højere end det normale vandniveau 24. Afstanden mellem fladen 25 og vandniveauet 24 er hensigtsmæssigt 40 til 60% af rørbøjningen 8's diameter.4 U4645 to allow the passage of even the above-mentioned waste, which should not occur. The outlet pipe 2 is connected to a drain line 3 under atmospheric pressure, which suitably has said reduced diameter. Between the outlet pipe 2 and the drain pipe 3 a pipe piece 4 is inserted with a pipe bend 8 shaped like a water trap and a common, horizontally extending pipe 5. A suitable length of the horizontal pipe is approx. 0.5 m. The pipes 4 and 5 are connected and connected to the outlet pipe 2 and the drain line 3 by means of 10 hinge brackets provided with hinge brackets 6. The pipe 4 has a vertical inlet part 11 and a horizontal outlet part 10 on each side of the U-shaped pipe bend 8. The level 24 of the water 9 standing in the pipe bend 8 is determined by the lower wall 27 of the horizontal outlet part 10. Unlike a water trap, however, the inlet part 11 and the outlet part 15 are usually in open communication with each other, the lowest surface 25 on the U The upper wall of the shaped pipe bend 8 is higher than the normal water level 24. The distance between the surface 25 and the water level 24 is suitably 40 to 60% of the diameter of the pipe bend 8.
20 Ved skylningen løber lidt mere end to liter vand fra skyllecisternen 7 ned i klosettet 1 og skyller dettes vægge. Denne lille vandmængde er ikke tilstrækkelig til at udføre det trykarbejde, som i konventionelle klosetter får affaldet ud af vandlåsen 26 og ind i afløbsledningen 3. I 25 klosetanlægget ifølge opfindelsen dannes der i rørstykket 4 imidlertid en sugekraft, som tømmer klosettets vandlås for affald. Denne sugekraft opstår på den måde, at der ved begyndelsen af skylningsforløbet løber vand fra klosettets vandlås 26 ned i rørstykket 4's omtrent til den halve højde fyldte, 30 vandlåslignende rørbøjning 8 og bringer det der værende vand 9 i bevægelse. Fordi den lige efter rørstykket 4 liggende del 5 af afløbsledningen forløber horisontalt, løber vandet 9 ikke hurtigere nedad, end at rørbøjningen 8 fyldes. Til opbremsning af vandstrømmen bidrager endvidere den omstændighed, 35 at en kraftig turbulens opstår i udløbsdelen 10, fordi vandet fra den U-formede rørbøjning 8 kastes op mod udløbsdelen20 When rinsing, a little more than two liters of water run from the rinsing tank 7 down into the toilet 1 and rinse its walls. This small amount of water is not sufficient to perform the pressure work which in conventional toilets gets the waste out of the water trap 26 and into the drain line 3. In the toilet system according to the invention, however, a suction force is formed in the pipe section 4 which empties the toilet water trap of waste. This suction force arises in such a way that at the beginning of the rinsing process water flows from the water trap 26 of the toilet down into the pipe part 4, which is approximately half the height, filled with water trap-like pipe bend 8 and moves the water 9 there. Because the part 5 of the drain line lying just after the pipe section 4 runs horizontally, the water 9 does not run downwards faster than the pipe bend 8 is filled. The fact that a strong turbulence occurs in the outlet part 10 also contributes to the slowing down of the water flow because the water from the U-shaped pipe bend 8 is thrown up against the outlet part.

5 144646 10's øvre væg. I den U-formede rørbøjning 8 og udløbsdelen 10 dannes altså en såkaldt vandprop, der bevæger sig til højre i fig. 2, og som fylder rørbøjningen 8. Derved opbygges et undertryk i rørstykket 4's lodrette del 11. Dette undertryk 5 suger affaldet ud af klosettet l's vandlås 26, hvorved endog det tidligere nævnte, utilbørlige affald tømmes ud af klosettet. Ved denne udsugning afgår der ikke en hel liter af vandlåsens ordinære vandindhold, hvorved den spærrende dybde 22 bliver omkring 10 mm.5 144646 10's upper wall. In the U-shaped pipe bend 8 and the outlet part 10, a so-called water plug is thus formed, which moves to the right in fig. 2, and which fills the pipe bend 8. Thereby a negative pressure is built up in the vertical part 11 of the pipe piece 4. This negative pressure 5 sucks the waste out of the water trap 26 of the toilet 1, whereby even the previously mentioned, inappropriate waste is emptied out of the toilet. With this extraction, not a whole liter of the ordinary water content of the water trap emits, whereby the blocking depth 22 becomes about 10 mm.
10 Skylningen af klosettet sker ved at man ved hjælp af en stang 28 løfter en ventil 29, som derved frilægger en åbning 30 i skyllecisternen 7's bund. Vandet i cisternen strømmer derpå gennem en kanal 23 til toiletskålen 1. Cisternen 7 indeholder endvidere et tragtformet rør 20, 15 hvis nedre del står i forbindelse med kanalen 23, og hvis øvre ende befinder sig over det normale vandniveau 21. Røret 20 sikrer, at vandet aldrig stiger højere end til rørets overkant.The flushing of the toilet takes place by lifting a valve 29 by means of a rod 28, which thereby exposes an opening 30 in the bottom of the flushing tank 7. The water in the cistern then flows through a channel 23 to the toilet bowl 1. The cistern 7 further contains a funnel-shaped pipe 20, 15 whose lower part communicates with the channel 23 and whose upper end is above the normal water level 21. The pipe 20 ensures that the water never rises higher than to the top of the pipe.
Efter en skylning vil vandniveauet i vandlåsen 26, 20 som tidligere nævnt, være lavere end det normale. For at genindstille vandlåsen 26's spærrende dybde til overensstemmelse med forskrifternes 50 mm, er der i skyllecisternen 7 indbygget et organ til vandlåsens efterfyldning. Denne efterfyldning sker samtidigt med skyllecisternen 7's genfyldning, idet der 25 fra vandledningsnettet føres vand gennem en tilslutningsledning 12 til skyllecisternen 7. Dette vand passerer et strømningsregulerende organ 13, som tilvejebringer en konstant strømning. Organet 13 kan f.eks. være af den art, der er beskrevet i beskrivelsen til dansk patent nr. 140572. På 30 ledningen 12 er der monteret en ventil 14, som via en arm 15 påvirkes af en svømmer 16, der styrer genopfyldningsforlø bet. Når vandfladen i skyllecisternen efter en skylning befinder sig i en nedre stilling 17, åbner ventilen 14. Derefter løber vand gennem et rør 18 meden afgrening 19. Gennem 35 røret 18 genfyldes skyllecisternen 7, medens en begrænset vandmængde strømmer gennem afgreningen 19 og ned 6After rinsing, the water level in the water trap 26, 20, as previously mentioned, will be lower than normal. In order to reset the locking depth of the water trap 26 to conform to the 50 mm of the regulations, a means for refilling the water trap is built into the rinsing tank 7. This refilling takes place simultaneously with the refilling of the rinsing tank 7, water 25 being led from the water supply network through a connecting line 12 to the rinsing tank 7. This water passes a flow regulating means 13, which provides a constant flow. The means 13 can e.g. be of the type described in the description of Danish patent no. 140572. A valve 14 is mounted on the line 12, which valve is actuated via an arm 15 by a float 16, which controls the refilling process. When the water surface in the rinsing tank after a rinsing is in a lower position 17, the valve 14 opens.

144665 i røret 20 og videre til klosettets vandlås. Idet organet 13 holder strømningen konstant under genopfyldningsforløbet, modtages der gennem afgreningen 19 præcis den vandmængde, som medgår til at efterfylde klosettet l's vandlås, medens 5 skyllecisternen 7 genfyldes. Hvis det tillades, at strømmen gennem røret 12 varierer, så vil forholdet mellem strømmene i rørene 18 og 19 forandres, hvilket indebærer, at tilstrømningen gennem røret 19 til vandlåsen 26 enten vil blive for stor eller for lille. Når vandfladen når op til stillingen 21, 10 er svømmeren 16 blevet løftet så højt, at ventilen 14 har lukket vandtilførslen, og klosettet er rede til et nyt skylningsforløb .144665 in the pipe 20 and on to the toilet water trap. As the means 13 keeps the flow constant during the refilling process, exactly the amount of water which is used to refill the water trap of the toilet 1 is received through the branch 19, while the rinsing tank 7 is being refilled. If the flow through the pipe 12 is allowed to vary, then the ratio of the flows in the pipes 18 and 19 will change, which means that the inflow through the pipe 19 to the water trap 26 will either be too large or too small. When the water surface reaches the position 21, 10, the float 16 has been lifted so high that the valve 14 has closed the water supply and the toilet is ready for a new flushing process.
