I DK 1999 00087 er der angivet en kendt lugtspærre af denne type, men den omfatter visse uhensigtsmæssigheder i forbindelse med rengøring og ved genmontage af ni-10 veaurør.DK 1999 00087 discloses a known odor barrier of this type, but it includes certain inconveniences in connection with cleaning and in the re-assembly of nine-tube pipes.

For at lette rengøringen af lugtspærren ifølge DK 1999 00087 kan det inderste rør, niveaurøret, fjernes for at give bedre plads til rengøring. Når niveaurøret genmonteres er det vigtigt for virkningen af lugtspærren, at røret kommer helt i bund i dets sæde.In order to facilitate the cleaning of the odor barrier according to DK 1999 00087, the inner tube, the level tube, can be removed to give better room for cleaning. When reassembling the level pipe, it is important for the effect of the odor barrier that the pipe is fully immersed in its seat.

15 Hvis ikke genmontagen er korrekt, kan der opstå problemer med, at spærrevæsken der sikrer, at der ikke kommer kloaklugt ud i lokalet, strømmer ud i kloakken, og dermed åbner for den uønskede lugt. Alternativt kan fejlmontering medføre at væskestanden i lugtspærren ifølge DK 1999 00087 hæves og i værste fald medføre at væske ikke kan strømme ud af lugtspærren. Denne fejlmontering opdages ofte ikke af rengøringsper-20 sonalet ved genmontage, og opdages således først ved næste rengøring. Dette kan selvsagt afstedkomme uønskede hændelser med urinaler uden vandlås/lugtspærre eller alternativt tilstoppede urinaler hvorfra væske ikke kan føres til kloak.15 If the reassembly is not correct, problems can occur that the barrier fluid, which ensures that no sewer odor enters the room, flows into the sewer, thus opening up the unwanted odor. Alternatively, incorrect mounting may result in raising the liquid level in the odor barrier according to DK 1999 00087 and in the worst case, liquid cannot flow out of the odor barrier. This fault mounting is often not detected by the cleaning staff on reassembly, and is thus not detected until the next cleaning. This can, of course, cause undesirable incidents with urinals without a water trap / odor barrier or alternatively clogged urinals from which fluid cannot be drained.

Det er formålet med en lugtspærrer ifølge opfindelsen, at angive en løsning på det 25 nævnte problem med fejlmontering af lugtspærrens enkeltdele, så det tydeligt afsløres, hvis der er sket en fejlmontering og som tillader fejlen at blive rettet hurtigt og bekvemt.It is the object of an odor barrier according to the invention to provide a solution to the problem of the aforementioned problem of malfunctioning the individual parts of the odor barrier so that it is clearly revealed if an error assembly has occurred and which allows the fault to be corrected quickly and conveniently.

En lugtspærre ifølge opfindelsen er udført med et niveaurør, hvis længde i det væsent-30 lige modsvarer afstanden fra dets sæde i bunden af det ydre rør og til undersiden af dækslet, hvor den opragende ende på niveaurøret er forsynet med en overløbssikring, DK 174577 B1 2 der samvirker med dækslet til afhjælpning af ukorrekt montage af niveaurøret samt som indikator for korrekt/ukorrekt montage.An odor barrier according to the invention is provided with a level tube whose length substantially corresponds to the distance from its seat at the bottom of the outer tube and to the underside of the cover, the projecting end of the level tube being provided with an overflow guard, DK 174577 B1. 2 which cooperates with the cover for rectifying incorrect level pipe installation and as indicator for correct / incorrect mounting.

For at undgå problemstillingen med fejlmontering udformes lugtspærren således, at 5 dækslet, der ligger over lugtspærren i samarbejde med niveaurøret, virker som en indikator for korrekt montage. Den opragende del af niveaurøret har til formål, at sikre ’ at niveaurøret altid genmonteres korrekt. Hvis niveaurøret ikke er monteret korrekt, , dvs. hvis det ikke er trykket helt i bund i sit sæde, kan dækslet ikke monteres, eller alternativt vil dækslet ikke kunne falde på plads i sin reces og giver derved indikation 10 om fejlagtig montage.To avoid the problem of malfunctioning, the odor barrier is designed so that the cover above the odor barrier in cooperation with the level tube acts as an indicator for correct mounting. The projecting part of the level tube is intended to ensure that the level tube is always reassembled correctly. If the level tube is not fitted correctly, ie. if it is not fully pressed into its seat, the cover cannot be fitted, or alternatively the cover will not be able to fall into place in its recess, thereby giving indication 10 of incorrect mounting.

Den del af det opragende niveaurøret, der modsvarer afstanden fra væskeoverfladen og op til undersiden af lugtspærrens dæksel udgør en overløbsfunktion og kan defineres som en overløbssikring. Denne overløbssikring kan, udover at sikre og opretholde en 15 væskestand, anvendes til - via dækslet - at udøve et tryk på niveaurøret hvorved en korrekt genmontage sikres. Dækslet kan så at sige anvendes som trykplade hvis niveaurøret er fejlmonteret og kan således blot trykkes på plads i sin reces.The portion of the projecting level tube corresponding to the distance from the liquid surface to the underside of the odor barrier cover constitutes an overflow function and can be defined as an overflow protection. In addition to securing and maintaining a fluid level, this overflow protection can be used - via the cover - to exert pressure on the level tube, thereby ensuring a correct reassembly. The cover can, so to speak, be used as a pressure plate if the level tube is incorrectly mounted and can thus simply be pressed into place in its recess.

En lugtspærrer ifølge opfindelsen har som nævnt en overløbssikring der i en foretruk-20 ken variant dannes ved at niveaurøret kan have en skråt afskåret ende, der vender mod dækslet, hvor den øverste ende af niveaurøret, i korrekt monteret tilstand, findes umiddelbart under dækslets underside.As mentioned, an odor barrier according to the invention has an overflow guard, which in a preferred variant is formed in that the level tube may have an obliquely cut end facing the cover, where the upper end of the level tube, in the correctly mounted state, is located immediately below the underside of the cover. .

En yderligere variant af en lugtspærrer ifølge opfindelsen kan være således udstyret at 25 nævnte overløbssikring udgøres af lugtspærrens niveaurør der er forsynet med åbninger i rørvæggen i den ende, der vender mod dækslet, hvor den øverste ende af niveaurøret, i korrekt monteret tilstand, findes umiddelbart under dækslets underside.A further variant of an odor barrier according to the invention may be such that said overflow protection is constituted by the level barrier of the odor barrier provided with openings in the tube wall at the end facing the cover, where the upper end of the level tube, in the correctly mounted state, is immediately found. beneath the underside of the cover.

Med denne løsning opnås samme effekt som nævnt ovenfor, nemlig at lugten fra klo-30 akken forhindres i at trænge ud i lokalet idet den skrå afskæring eller åbningerne i rørvæggen bevirker, at der i lugtspærren opretholdes den nødvendige/ønskede mængde væske.With this solution, the same effect as mentioned above is obtained, namely that the odor from the socket is prevented from penetrating into the room as the sloping cut or the openings in the pipe wall cause the required / desired amount of liquid to be maintained in the odor barrier.

3 DK 174577 B1 I en foretrukken variant af en lugtspærrer ifølge opfindelsen er både det samlede areal hvorigennem væske strømmer ud af niveaurøret og ringarealet mellem niveaurør og afgangsrør, større end det samlede areal af tilgangsåbninger i dækslet, hvorved det 5 sikres, at der ved skylning med en spand vand eller lignende forud for rengøring ikke opstår problemer såsom utilsigtet udskylning af spærrevæske.In a preferred variant of an odor barrier according to the invention, both the total area through which fluid flows out of the level tube and the ring area between level tubes and outlet pipes is greater than the total area of inlet openings in the cover, thereby ensuring that, upon rinsing, with a bucket of water or the like prior to cleaning, problems such as unintentional flushing of the blocking fluid do not occur.

I det følgende beskrives opfindelsen under henvisning til tegningen, der uden at skulle virke begrænsende, viser en foretrukken udførelse af en lugtspærre ifølge opfindelsen, 10 hvor:In the following, the invention is described with reference to the drawing which, without being limiting, shows a preferred embodiment of an odor barrier according to the invention, wherein:

Fig. 1 viser et tværsnit af en lugtspærre 2 ifølge opfindelsen, hvor lugtspærren 2 er sammenbygget med et urinal 4 af den vandløse type, og hvor dens enkeldele tydeligt ses. Urinaler af den vandløse type virker ved, at der i stedet for skylninger med vand findes en spærrevæske 6, med en vægtfylde der er mindre end vand/urin 8, i lugtspær-20 ren 2. Denne type urinaler 4 anvendes ofte på offentlig tilgængelige toiletter, hvor der herved spares meget vand.FIG. 1 is a cross-sectional view of an odor barrier 2 according to the invention, wherein the odor barrier 2 is combined with a urinal 4 of the waterless type and its single parts are clearly visible. The waterless type urinals work in that, instead of rinsing with water, there is a barrier liquid 6, with a density less than water / urine 8, in the odor barrier 20. This type of urinals 4 is often used on publicly accessible toilets , which saves a lot of water.

Lugtspærren 2 består i princippet af 3 rør, nemlig et ydre rør 10, et afgangsrør 12 og et niveaurør 14. Det ydre rør 10 udgør den beholder, der indeholder spærrevæske 6, 8, og 25 hvori niveaurøret 14 monteres. Afgangsrøret 12 er fast forbundet til dækslet 16 og er det rør, der sammen med niveaurøret 14 bevirker, at lugten fra kloakken forhindres i at trænge ud i lokalet.The air barrier 2 consists in principle of 3 pipes, namely an outer pipe 10, a discharge pipe 12 and a level pipe 14. The outer pipe 10 constitutes the container containing barrier liquid 6, 8 and 25 in which the level pipe 14 is mounted. The outlet pipe 12 is firmly connected to the cover 16 and is the pipe which, together with the level pipe 14, prevents the smell from the sewage from entering the room.

Ved rengøring af lugtspærren 2 fjernes dækslet 16 og dermed afgangsrøret 12. Deref-30 ter fjernes niveaurøret 14, og den væske 6, 8 der er samlet i lugtspærren 2 strømmer ud i kloakken. Når niveaurøret 14 er fjernet, kan der let rengøres i lugtspærren 2, da der nu ikke længere findes forstyrrende elementer i lugtspærren 2. Når niveaurøret 14 igen 4 DK 174577 B1 skal monteres sikres det at de tætningsmidler 18, der skal være mellem det ydre rørs bunddel 20 og niveaurøret 14 er intakt og korrekt monteret. Herefter presses niveaurøret 14 på plads i sit sæde 22 i bunden 20 af lugtspærren 2.By cleaning the odor barrier 2, the cover 16 is removed and thus the exhaust pipe 12. Then the level tube 14 is removed and the liquid 6, 8 collected in the odor barrier 2 flows into the sewer. Once the level tube 14 has been removed, the odor barrier 2 can be easily cleaned, as there are no longer any disturbing elements in the odor barrier 2. When the level tube 14 is again to be mounted, it is ensured that the sealing means 18 to be between the outer tube bottom portion 20 and level tube 14 are intact and properly mounted. Next, the level tube 14 is pressed into place in its seat 22 at the bottom 20 of the odor barrier 2.

5 Den øverste ende af niveaurøret 14 er her udført med en skråt afskåret ende 24, således at længden på niveaurøret 14 i det væsentlige modsvarer afstanden fra bunden af niveaurørets sæde 22 og op til undersiden af dækslet 16. Den skrå afskæring 24 har en , vinkel, der bevirker at der i lugtspærren 2 opretholdes den nødvendige/ønskede mængde væske 6, 8.Here, the upper end of the level tube 14 is provided with an obliquely cut end 24 such that the length of the level tube 14 substantially corresponds to the distance from the bottom of the level tube seat 22 to the underside of the cover 16. The oblique cut 24 has an angular which causes the required / desired amount of liquid 6, 8 to be maintained in the odor barrier 2.

10 I fig. 2 ses en variant af niveaurøret 14, hvor der i stedet for en skrå afskåret ende 24 er åbninger 26 i rørvæggen, der tillader passage af den nødvendige mængde væske 6,8.10 In FIG. 2 shows a variant of the level tube 14, where instead of an obliquely cut end 24 there are openings 26 in the tube wall which allow passage of the required amount of liquid 6.8.

Denne variant har den samme højde som niveaurøret 14 med den skrå ende 24.This variant has the same height as the level tube 14 with the inclined end 24.

15 Disse to typer niveaurør 14 har den egenskab, at hvis de ikke monteres korrekt så ses det tydeligt på placeringen af dækslet 16, der så ikke kan falde på plads i sit sæde 28.15 These two types of level tubes 14 have the property that if they are not mounted correctly, it is clearly visible on the location of the cover 16, which then cannot fall into place in its seat 28.

Derved fremgår det tydeligt, at niveaurøret 14 ikke er korrekt monteret. Hvis dækslet 14 ikke falder på plads, kan man eventuelt bringe montagen i orden ved at presse dækslet 16 på plads, hvorved også niveaurøret 14 presses på plads i sit sæde 22.This makes it clear that the level tube 14 is not mounted correctly. If the cover 14 does not fall into place, it is possible to put the assembly in order by pressing the cover 16 in place, whereby the level tube 14 is also pressed into place in its seat 22.

Fig. 3 viser hvordan dæksel 16, udsparinger 30 og anlægsfladen 28 for dækslet 16 er udformet.FIG. 3 shows how the cover 16, recesses 30 and the abutment surface 28 of the cover 16 are designed.

Det samlede areal af de udsparinger 30 der er i dækslet 16 bør altid være mindre end 25 det virksomme areal, der tillader væske 6,8 at strømme ud af niveaurøret 14, såvel som mindre end arealet mellem niveaurør 14 og afgangsrør 12, hvorved det sikres, at f der ved skylning med en spand vand eller lignende forud for rengøring ikke opstår problemer såsom utilsigtet udskylning af spærrevæske.The total area of the recesses 30 in the cover 16 should always be less than 25 the effective area allowing liquid 6.8 to flow out of the level tube 14, as well as less than the area between level tube 14 and discharge tube 12, thereby ensuring , that when rinsing with a bucket of water or the like prior to cleaning, no problems such as unintentional flushing of blocking fluid occur.
