Abstract

Opfindelsen angår en afløbsrende (101) indrettet til at lede afløbsvand imod et afløb, og hvor denne omfatter en konkav skalform (103) med sidevægge. Afløbsrenden er i dennes bunddel udformet med en bundrende (107). Denne bundrende er mindre end afløbsrenden, og derved kræves der mindre afløbsvand i denne, før den leder afløbsvandet imod et afløb. Selv mindre mængder afløbsvand kan nu ledes imod et afløb, hvorved man undgår, at der står vand i renderne.BACKGROUND OF THE INVENTION The invention relates to a drainage channel (101) adapted to direct drainage water towards a drainage, the latter comprising a concave shell form (103) with side walls. The drain channel is formed in its bottom part with a bottom gutter (107). This bottom drain is smaller than the drainage channel, and therefore less drainage water is required in it before it directs the drainage water towards a drain. Even smaller amounts of wastewater can now be directed towards a drain, thereby avoiding water in the channels.

Afløbsrende med bundrende Omfang af opfindelsenDrain Pipe with Bottom Scope of the Invention

Den foreliggende opfindelse angår afløbsrende indrettet til at lede afløbsvand imod et 5 afløb, hvor afløbsrenden i dennes bunddel er udformet med en bundrende, og hvor afløbsrenden omfatter en konkav skalform med sidevægge.BACKGROUND OF THE INVENTION The present invention relates to drainage channels adapted to conduct drainage water against a drain, wherein the drainage channel in the bottom part thereof is formed with a bottom drainage, and the drainage channel comprises a concave shell shape with side walls.

Baggrund for opfindelsen I forbindelse med gulvafløb, eksempelvis i forbindelse med vådrum i produktionsom-10 råder i slagterier eller lignende, kan der være placeret aflange render i gulvet, der har en hældning, hvorved overskydende vand via renderne ledes hen til et afløb.BACKGROUND OF THE INVENTION In connection with floor drains, for example in connection with wet rooms in production areas in slaughterhouses or the like, elongated troughs may be located in the floor having a slope whereby excess water via the trenches is led to a drain.

Ved mindre mængder af afløbsvand kan dette ikke ledes videre af rendernes hældning, og derfor grundet vandets overfladespænding ligger dette i bunden af renderne, indtil 15 det bliver skyllet ud sammen med større mængder af afløbsvand. Disse mindre mængder af afløbsvand, eksempelvis vanddråber, kan ligge i bunden i længere perioder, hvilket kan skabe kalkaflejringer i renden, når de fordamper, eller der dannes bakterier, hvis vandet går i forrådnelse.With smaller amounts of wastewater, this cannot be passed on by the slope of the channels, and therefore due to the surface tension of the water, this lies at the bottom of the channels until it is flushed out together with larger amounts of wastewater. These smaller amounts of wastewater, for example water droplets, can remain in the bottom for extended periods, which can create limescale deposits in the gutter as they evaporate or bacteria form if the water goes into decay.

20 Der kendes fra WO2010/047720 Al en afløbsrende af den indledningsvis nævnte type. Der er heri bekrevet plane sidevægge, der mødes ved skarpe hjørner. Ved disse hjørner kan der samles afløbsvand, som kan ligge i længere perioder og giver anledning til de ovenfor omtalte problemer. Selv om bundrenden har mindre tværsnit end afløbsrendens øvre hoveddel, så har den en plan bund. På denne plane bund kan min-25 dre mængder af afløbsvand, eksempelvis vanddråber, ligeledes ligge i længere perioder og giver derfor også anledning til de ovenfor omtalte problemer.WO2010 / 047720 A1 discloses a drainage channel of the type mentioned initially. There are described flat side walls herein which meet at sharp corners. At these corners, wastewater can accumulate, which may linger for longer periods and give rise to the problems mentioned above. Although the bottom gutter has a smaller cross-section than the upper body of the drain gutter, it has a flat bottom. On this flat bottom, lesser amounts of wastewater, for example water droplets, can also lie for longer periods and therefore also give rise to the problems mentioned above.

Formål med opfindelsenObjects of the Invention

Et formål med opfindelsen er at løse ovennævnte problemstillinger, herunder at finde 30 frem til en afløbsrende, hvor man kan undgå, at der står vand i bunden af denne.An object of the invention is to solve the above-mentioned problems, including finding a drainage channel where water can be avoided at the bottom of it.

Beskrivelse af opfindelsenDescription of the Invention

Det opnås ifølge den foreliggende opfindelse med en afløbsrende af den indledningsvis nævnte type, som er særpræget ved, at afløbsrendens skalform er en skalform, der har buede sidevægge med en første rundingsradius, og at bundrendens sidevægge er 5 buede og har en anden rundingsradius mindre end den første rundingsradius.It is achieved in accordance with the present invention with a drain channel of the type mentioned in the introduction, which is characterized in that the shell shape of the drain channel is a shell shape having curved side walls with a first rounding radius and that the bottom channel side walls are curved and having a second round radius less than the first rounding radius.

Derved dannes en lille rende i bunden af afløbsrenden, hvor afløbsvand kan samles uafhængigt af den øvrige rendes dimensioner. Ved at danne en lille bundrende ved hjælp af de buede sidevægge kan antallet af skarpe hjørne undgås/minimeres. Dette er 10 specielt en fordel, da skarpe hjørner er mere følsomme for brud, når afløbsrenden er dannet ved at bukke plademateriale. Yderligere kan sådanne skarpe hjørner bremse vandråber på vej imod bundrenden.Thereby a small gutter is formed at the bottom of the drainage channel, where drainage water can be collected independently of the other channel's dimensions. By forming a small bottom edge using the curved side walls, the number of sharp corners can be avoided / minimized. This is especially advantageous as sharp corners are more sensitive to fracture when the drainage gutter is formed by bending sheet material. Further, such sharp corners can slow down water droplets on their way to the bottom edge.

Bundrenden er mindre end afløbsrenden, og derved kræves der mindre afløbsvand i 15 bundrenden, før den leder afløbsvandet imod et afløb. Selv mindre mængder afløbsvand kan nu ledes imod et afløb, hvorved man undgår, at der står vand i renderne. Ligeledes vil den konkave form gøre det muligt at undgå skarpe kanter, som kan være med til at vand opsamles i bunden af afløbsrenden og ikke ledes ud. Ligeledes vil bundrenden ikke have en plan bund, hvilket yderligere bidrager til, at afløbsrenden 20 tømmes effektivt for afløbsvand.The bottom gutter is smaller than the drain gutter, and thus less drainage water is required in the bottom gutter before it directs the drain water towards a drain. Even smaller quantities of wastewater can now be directed towards a drain, avoiding the fact that there is water in the channels. Likewise, the concave shape will allow sharp edges to be avoided, which may help to collect water at the bottom of the drainage channel and not escape. Likewise, the bottom gutter will not have a flat bottom, which further contributes to the drain gutter 20 being effectively emptied of wastewater.

I en udførelsesform er den anden rundingsradius 1/4 af den første rundingsradius. Dette har vist sig at være en fordelagtig dimensionering i forhold til at opnå optimal ledning af spildevand imod afløb.In one embodiment, the second rounding radius is 1/4 of the first rounding radius. This has proven to be an advantageous design in relation to obtaining optimum conduction of wastewater against drains.

25 I en udførelsesform udgør bundrendens højde under 1/5 af afløbsrendens samlede ren-dehøjde. Dette har vist sig at være en fordelagtig dimensionering i forhold til at opnå optimal ledning af spildevand imod afløb.In one embodiment, the bottom channel height is less than 1/5 of the overall channel height of the drain. This has proven to be an advantageous design in relation to obtaining optimum conduction of wastewater against drains.

30 I en udførelsesform er afløbsrenden udført af en bukket stålplade. Dette er en simpelproduktionsform og ligeledes har stål gode hygiejneegenskaber i relation til efterfølgende rengøring af renderne.In one embodiment, the drainage channel is made of a bent steel plate. This is a simple form of production and also steel has good hygienic properties in relation to subsequent cleaning of the gutters.

Opfindelsen vil herefter blive forklaret nærmere under henvisning til den medfølgende tegning, hvor 5 fig. 1A-D viser en afløbsrende ifølge opfindelsen, set fra forskellige vinkler.The invention will now be explained in more detail with reference to the accompanying drawing, in which: FIG. 1A-D show a drainage channel according to the invention, seen from different angles.

Detaljeret beskrivelse af opfindelsenDetailed description of the invention

Fig. 1A-D illustrerer en første udførelsesform af en afløbsrende 101 med en bundrende 107, og hvor det er set fra forskellige vinkler, og hvor fig. 1A er et tværsnit, fig. IB er 10 set skråt fra oven, fig. 1C er set fra siden, og fig. ID er set fra oven.FIG. 1A-D illustrate a first embodiment of a drain channel 101 with a bottom channel 107 and where viewed from different angles and in which FIG. 1A is a cross-section, FIG. 1B is an oblique view from above; FIG. 1C is a side view, and FIG. ID is seen from above.

Afløbsrenden 101 er indrettet til at lede afløbsvand imod et afløb, og omfatter en konkav skalform 103 med sidevægge. I bunden af afløbsrenden er der udformet en bundrende 107.The drainage trough 101 is arranged to conduct drainage water against a drain, and comprises a concave shell mold 103 with side walls. A bottom 107 is formed at the bottom of the drainage gutter.

Bundrenden 107 danner en mindre rende i forhold til afløbsrenden 101, hvorved små mængder afløbsvand kan samles i denne og danne en, i forhold til bundrenden, relativ stor mængde afløbsvand i forhold til den relativ lille eller smalle bundrende 107.The bottom gutter 107 forms a smaller gutter relative to the drain gutter 101, whereby small amounts of drain water can be collected therein and form a relatively large amount of drain water relative to the relatively small or narrow bottom gutter 107 relative to the bottom gutter.

20 For at opnå en bundrende, som kan samle og lede selv forholdsvis små mængder afløbsvand har afløbsrendens konkave skalform sidevægge med en første hældning 105, og bundrendens sidevægge har en anden hældning 109 stejlere end den første hældning 105. Disse hældninger kan tilpasses i forhold til mængden af afløbsvand afhængigt af produktionsområdet, hvor afløbet er placeret.20 In order to obtain a bottom channel which can collect and conduct even relatively small amounts of drainage water, the drainage channel's concave shell form has sidewalls with a first slope 105, and the bottom channel sidewalls have a second slope 109 steeper than the first slope 105. These slopes can be adapted to the amount of wastewater depending on the production area where the drain is located.

25 Både bundrende og afløbsrende kan have lige skrå sider, men alternativt, og som vist på figuren, har afløbsrenden buede sidevægge med en første rundingsradius markeret med 105, og bundrenden har sidevægge med en anden rundingsradius markeret ved 109, og som er mindre end den første rundingsradius.Both bottom and drain channels may have equally inclined sides, but alternatively, and as shown in the figure, the drain channel has curved side walls with a first radius of radius marked with 105, and the bottom channel has sidewalls with a second radius of radius marked at 109, which is smaller than the one. first rounding radius.

Den første rundingsradius kan være på ca. 60 mm, hvor den anden radius kan være på 15 mm, som er ca. 1/4 af den første rundingsradius.The first rounding radius may be approx. 60 mm, the second radius being 15 mm, which is approx. 1/4 of the first rounding radius.

DK 177813 B1 4 På figuren fremgår det, at højden 113 på bundrenden er betydeligt mindre end højden 111 på hele afløbsrenden.DK 177813 B1 4 The figure shows that the height 113 of the bottom gutter is considerably smaller than the height 111 of the entire drain gutter.

Afløbsrenden vist på figuren er udført i en bukket plade, fortrinsvis af stål.The drainage channel shown in the figure is made in a bent plate, preferably of steel.

55

Opfindelsen er ikke begrænset til de på figurerne viste og ovenfor beskrevne udførelsesformer. Andre udførelsesformer med andre former af afløbsrenden er tænkelige indenfor rammerne af denne opfindelse og de efterfølgende krav.The invention is not limited to the embodiments shown in the figures and described above. Other embodiments with other forms of the drainage channel are conceivable within the scope of this invention and the subsequent claims.
