Opfindelsen angår en vandlås af punglåstypen, bestående af en skålformet underdel og en udtagelig, tragtformet indsats, hvis ydre omfang forneden er mindre end den skålformede underdels indre omfang, og som er udformet til 5 indsætning oppefra i den skålformede underdel og til at rage ned i skålen og at ende i afstand fra dennes bund ved hjælp af afstandsribber, der holder indsatsens øvre ende i afstand fra den skålformede underdels øvre ende under dannelse af afgangsåbninger imellem de to dele.BACKGROUND OF THE INVENTION The invention relates to a purse-type water trap consisting of a bowl-shaped base and a removable funnel-shaped insert, the outer scope of which is lower than the inner size of the bowl-shaped base, and which is designed for insertion from the top into the bowl-shaped base and protruding into it. the bowl and ending at a distance from the bottom thereof by means of spacers which keep the upper end of the insert away from the upper end of the bowl-shaped base to form outlet openings between the two parts.

10 Det har vist sig, at afstandsribberne hurtigt kan komme til at fange smudspartikler i så væsentlige mængder, at der fremkommer en uønsket tilstopning af de nævnte afgangsåbninger. Formålet med opfindelsen er at angive, hvorledes denne gene kan imødegås.10 It has been found that the spacer ribs can quickly catch dirt particles in such substantial quantities as to cause undesired clogging of said outlet openings. The object of the invention is to indicate how this nuisance can be countered.

15 Dette er ifølge opfindelsen opnået ved, at der i det mindste ud for afstandsribberne imellem den tragtformede indsats og den skålformede underdel er anbragt skillevægge, som opdeler det mellem indsatsen og underdelen dannede ringrum i enkelte gennemstrømningsafsnit.This is achieved according to the invention by separating partitions at least along the distance ribs between the funnel-shaped insert and the cup-shaped bottom partition, which divide the annular space formed between the insert and the bottom part in individual flow sections.

20 Disse skillevægge gør det muligt at meddele det af gående vand et sådant strømningsforløb, at der undgås generende aflejring af smudspartikler i området omkring afstandsribberne.These partitions make it possible to impart to the flow of running water such that nuisance deposits of dirt particles are avoided in the area around the spacers.

En særlig fordelagtig udførelsesform for vandlåsen 25 består ifølge opfindelsen i, at rumfanget af det nævnte ringrum, som begrænses af en del af den tragtformede indsats, udformes mindre end rumfanget af den af samme del begrænsende del af indsatsens inderrum, og at skillevæggene strækker sig i det mindste langs en væsentlig del af indsatsens nedre 30 ende.A particularly advantageous embodiment of the water trap 25 according to the invention consists in that the volume of said annulus, which is limited by a portion of the funnel-shaped insert, is formed less than the volume of the part-limiting part of the inner space of the insert and that the partitions extend in at least along a substantial portion of the lower end of the insert.

Denne særlige udformning af rumfangsforholdene medfører, at vandtrykket i det fra låsen afgående vand forøges.. Anvendt i forbindelse med den for opfindelsen karakteristiske anbringelse af skillevæggene opnås herved en særlig god 35 renholdelse af vandlåsen for aflejring af smudspartikler. I traditionelle vandlåse uden sådanne skillevægge vil der 2 DK 168768 B1 selv ved forøget vandtryk forekomme generende aflejringer af smudspartikler omkring afstandsribberne.This particular design of the volume ratio causes the water pressure in the water exiting from the lock to increase. Used in connection with the arrangement of the partitions characteristic of the invention, a particularly good cleaning of the water trap for deposition of dirt particles is achieved. In traditional water locks without such partitions, even with increased water pressure, nuisance deposits of dirt particles around the spacers will occur.

En udførelsesform for vandlåsen ifølge opfindelsen skal i det følgende forklares nærmere under henvisning til 5 tegningen, på hvilken fig. 1 skematisk viser et længdesnit igennem vandlåsen, og fig. 2 et tværsnit efter linien II-II i fig. 1.An embodiment of the water trap according to the invention will be explained in the following with reference to the drawing, in which fig. 1 is a schematic longitudinal section through the water trap; and FIG. 2 is a sectional view taken along line II-II of FIG. First

Den på tegningen viste vandlås af punglåstypen består 10 af en skålformet underdel 10 og en tragtformet indsats 12, der udtageligt er indsat oppefra i underdelen 10. Indsatsen 12 har en i det væsentlige keglestubformet øvre part 14, og en cylindrisk nedre part 16.The purse-type water trap shown in the drawing 10 consists of a bowl-shaped bottom part 10 and a funnel-shaped insert 12 which is removably inserted from above in the bottom part 10. The insert 12 has a substantially cone-shaped upper part 14, and a cylindrical lower part 16.

Underdelen 10 har forneden en skålformet part 18, og 15 foroven en ringformet part 20, der ved hjælp af afstandsribber 22 er forbundet med parten 18, hvorved der mellem parterne 18 og 20 dannes ved pile 24 markerede afgangsåbninger, hvis sidebegrænsninger er dannet af ribberne 22.The lower part 10 has a bowl-shaped part 18 below and 15 above an annular part 20, which is connected to the part 18 by means of spacers 22, whereby opening portions marked by arrows 24 are formed between the parts 18 and 20, whose lateral restrictions are formed by the ribs 22 .

Indsat i underdelen hviler indsatsen. 1-2- med sin øvre 20 part ved hjælp af ikke nærmere beskrevne skuldre på tilsvarende kontraskuldre af underdelen 10's ringformede part 20. Indsatsen 12's nedre part 16 ender som vist i afstand fra underdelen 10's bund 26. Parten 16 danner sammen med underdelen 10' s part 18 et ringformet gennemstrømningsrum 28, 25 således at oppefra igennem indsatsen tilstrømmende vand atter kan forlade vandlåsen via ringrummet 28 og afgangsåbningerne 24.Inserted into the lower part rests the insert. 1-2- with its upper 20 part by means of unspecified shoulders on corresponding contrast shoulders of the annular part 20. The lower part 16 of the insert 12 ends as shown at a distance from the bottom 26. The part 16 forms together with the lower part 10 '. s 18, an annular flow space 28, 25 so that water flowing through the insert can again leave the water trap via the annulus 28 and the outlet openings 24.

I den viste udførelsesform er der på indsatsen 12's yderside anbragt skillevægge 30, der er placeret ud for 30 afstandsribberne 22 og i den viste udførelsesform strækker sig hele vejen ned over indsatsen 12's nedre part 16. Ved hjælp af disse skillevægge opdeles ringrummet 28 i enkelte, gennemstrømningsafsnit 28a, som det bedst fremgår af fig.In the illustrated embodiment, partition 30 is disposed on the outside of the insert 12 which is positioned beyond the spacer ribs 22 and in the illustrated embodiment extends all the way down to the lower portion 16. The annular space 28 is divided into individual, flow section 28a, as best seen in FIG.

2. Herved opnås sådanne strømningsforløb, at aflejringer af 35 smudspartikler bagfra i området omkring afstandsribberne 22 modvirkes.2. In this way, flow flows are obtained so that deposits of 35 dirt particles from behind in the area around the spacers 22 are counteracted.

Ringrummet 28’s rumfang er mindre end rumfanget af indsatsen 12's part 16, hvorved der i ringrummet fremkaldes et forøget vandtryk. Dette kan udnyttes fuldtud til yderligere renholdelse af afgangsåbningerne 24.The volume of the annulus 28 is smaller than the volume of the part 16 of the insert 12, thereby causing an increased water pressure in the annulus. This can be fully utilized for further cleaning of the outlet openings 24.
