Description

The invention relates to an odor trap according to the preamble of claim 1. The invention also relates to a drain pan and a drain system.

Various types of odor traps are known. Due to its structure, an odor trap forms a barrier fluid layer that prevents the passage of gases, for example from the sewer system.

An odor trap with the features of the preamble of claim 1 is, for example, from EP 3 117 047 B1 known. EP 3 117 047 B1 describes a drain fitting which comprises a floor drainage channel with a housing arranged at a drain opening. The housing has a housing cover and a housing pot. An odor trap is arranged in the housing. The odor trap comprises a dip tube and a cup-shaped container. The immersion tube comprises a flange which is arranged on webs protruding radially inward in the housing cover.

The one out EP 3 117 047 B1 known odor trap has the disadvantage that the immersion tube is not well attached, since the immersion tube with the flange only rests loosely on the webs. It is possible that the immersion tube changes position, for example slipped. This can impair the function of the odor trap or even completely lose it. It is also necessary that the odor trap is removed from time to time for maintenance or cleaning. The known odor trap has the disadvantage that removing the odor trap from the housing of the drain fitting is costly, since the immersion tube and the container can only be removed individually from the housing.

The present invention is therefore based on the object of specifying an odor trap in which the fastening of the dip tube to the container is improved. It is also an object of the invention to specify a drainage pot and a drainage system.

• den Ablauftopf durch den Gegenstand des Anspruchs 10 und
• das Ablaufsystem durch den Gegenstand des Anspruchs 14

gelöst.According to the invention, this object is achieved with a view to

• the odor trap by the subject matter of claim 1,
• the drain pan by the subject matter of claim 10 and
• the drainage system by the subject matter of claim 14

solved.

Specifically, the object is achieved by an odor trap for arrangement in a drainage pot comprising an upper part that has a dip tube and a lower part that has a container that is open at the top, the dip tube protruding into the container in the assembled state, and the upper part has at least one latching element on an outer surface of the dip tube and the lower part has at least one latching receptacle on an inner surface of the container, the upper part and the lower part being detachably positively and / or non-positively connected to one another by the latching element and the latching receptacle.

The advantage of the invention is that the immersion tube and the container, which is open at the top, are releasably non-positively and / or positively connected to one another by the latching element and the latching receptacle. The connection is strong enough to withstand external forces, but can still be released by hand.

Open at the top means that the opening of the container is arranged at the top in the direction of gravity in the assembled state. This means that a fluid can flow into the container in the direction of gravity.

The snap-in connection between the immersion tube and the container enables the odor trap to be set up and assembled easily. This means that the odor trap can be installed quickly and easily. Furthermore, the odor trap can be removed or installed as a unit. This makes the odor trap easy to maintain and clean.

Preferred embodiments of the invention are specified in the subclaims.

In a particularly preferred embodiment, the latching element has a latching geometry, in particular a cylindrical latching geometry, which is arranged on the outer surface of the immersion tube. The latching geometry is advantageous because it enables the latching connection to be held particularly well. The locking geometry can be adapted to the locking receptacle. Different shapes can be used as the locking geometry. Cylindrical, rectangular or polygonal shapes are possible.

In a further particularly preferred embodiment, the locking element has a spring element, in particular a slot, which extends parallel to a longitudinal axis of the immersion tube and is arranged centrally on the locking element. The spring element has the advantage that it facilitates the insertion of the locking element into the locking receptacle. The spring element, for example through the slot, allows the locking element to be compressed or compressed so that it can be pushed past a narrowing into the locking receptacle and then expand again when the locking element is arranged in the locking receptacle. The locking geometry returns to its uncompressed initial state. As a result, the locking element is arranged in the locking receptacle in a form-fitting and / or force-fitting manner.

The latching receptacle further particularly preferably comprises two webs, the webs each having an inner contour for receiving the latching geometry of the latching element, in particular the cylindrical latching geometry.

The latching geometry preferably has an outer contour, the inner contour of the webs corresponding at least in sections to the outer contour of the latching geometry.

In the installed state, the latching geometry is arranged between the inner contours of the webs. The latching geometry is preferably cylindrical, for example as a pin. The diameter or the width of the latching geometry preferably corresponds essentially to the spacing of the webs in the area of the bulges from one another. The locking geometry is arranged in the locked state in the inner contour. In this case, the latching geometry on the outer contour rests, at least in sections, on the inner contours of the webs. The constriction is arranged from the opening of the container in front of the inner contour of the webs.

In one embodiment, the immersion tube comprises two longitudinal and two transverse sides, the immersion tube merging into a collar at one axial end in a funnel shape. This is advantageous because the funnel-shaped collar improves the flow behavior of the fluid to be diverted. This means that larger amounts of fluid, for example waste water, can be discharged.

Holding means, in particular handles or tabs, which each extend in the direction of the opposite side, are preferably arranged on two opposite sides of the collar. The handles are useful when the odor trap needs to be removed from the drain pan for maintenance or cleaning. The immersion tube and the container can be removed and serviced as a unit or separately, one after the other.

In a further particularly preferred embodiment, the upper part has at least one support element, in particular a rib or a wing, a circumferential gap being formed by the support element in the assembled state between an upper edge of the container and an underside of the collar of the dip tube, the height of the gap is between 2 mm and 35 mm, in particular between 5 mm and 30 mm, in particular between 10 mm and 25 mm, in particular between 15 mm and 20 mm. The gap allows the fluid to drain into the drainage pot. Depending on the size and volume flow of the fluid, it is advantageous to vary the width of the gap. The height of the gap is preferably 8 mm.

It is advantageous if the fluid-conducting sections of the container and the dip tube are rounded. This improves the fluid-conducting properties of the odor trap. Furthermore, in this way the odor trap remains largely free of soiling. Since there are no surfaces on which residual fluid can remain, the dirt is continuously removed or washed away with the fluid to be discharged.

In the context of the invention, a drain pot for discharging a fluid, in particular waste water, is disclosed and claimed, the drain pot having side walls, and the side walls being convex outward and the drain pot having at least one connection area, in particular at least two connection areas, which can be connected with a connecting piece.

The side walls are preferably arched or curved convexly outward in the circumferential direction and / or along the central longitudinal axis of the drain pot. The central longitudinal axis runs orthogonally to the bottom of the drainage pot. The curvature or curvature preferably extends from the opening in the direction of the closed bottom of the drainage pot. The side walls are designed in particular spherical, spherical or bulb-shaped. In particular, the side walls are essentially circular arc-shaped in a cross section of the drain pot.

It is advantageous if the side walls are curved along their entire length in the circumferential direction and / or in the direction of the central longitudinal axis. Alternatively, it is conceivable that the side walls are only partially or partially curved convex outward. In particular, it is advantageous if a non-curved section is provided in the area of the opening. This allows the drain pan to be butt welded.

The advantage of the drain pan is that the convex curvature of the side walls and the associated larger volume of the drain pan enable good drainage values for small sizes. It is also possible to connect the drainage pot to several connecting pieces or to freely choose the side on which the connecting piece is connected to the drainage pot.

It is particularly advantageous if the connection piece is flush with the bottom of the drainage pot in the assembled state. This allows the drain pan to run completely empty so that no fluid remains in the drain pan. This reduces dirt residues.

It is also particularly advantageous if the at least one connection area has a funnel-shaped contour. In other words, the connection area has a conical area. As a result, the flow behavior of the fluid in this area is improved to the effect that the fluid can flow away more quickly.

In order to fasten the drainage pot in a soil material, the drainage pot has at least one anchor element, in particular beads, on an outer surface. The anchor element is also advantageous in order to stiffen and reinforce the side walls. This is necessary because the side walls are made of a relatively thin material.

In the context of the invention, a drain system comprising an odor trap according to one of claims 1 to 9 and a drain pot according to one of claims 10 to 13 is disclosed and claimed, the drain pot being connected to a drainage channel, in particular welded, and the odor trap being arranged in the drain pot .

The drainage channel and the drainage pot are preferably made of metal, in particular stainless steel. The upper part and the lower part are preferably each formed in one piece or monolithically from a plastic, for example by injection molding. As a result, the production costs can be reduced.

In a preferred embodiment, the drainage channel has an end plate, the end plate having at least one elongated hole and / or at least one bore. The at least one elongated hole makes it possible to determine the installation height of the drainage system in the floor material and to anchor the drainage system. The hole is advantageous for grounding the drainage system.

The invention is explained in more detail below on the basis of exemplary embodiments with reference to the accompanying drawings.

The Figures 1 to 6 relate to an odor trap 10.

In the Figures 1, 2 and 3 an upper part 11 of the odor trap 10 is shown. The upper part 11 comprises a dip tube 12. The dip tube 12 has two straight longitudinal sides and two circular arc-shaped transverse sides. At one axial end, the immersion tube 12 has a funnel-shaped transition to a collar 23.

The funnel-shaped transition is advantageous for the drainage property, since the fluid to be drained can be drained off quickly. The collar 23, in particular the outer edge of the collar 23, comprises a sealing lip which, in the installed state, seals the odor trap 10 to the outside, for example against a drainage body.

A latching element 15 is arranged in each case on an outer surface A 'of the transverse sides. The latching element 15 comprises a latching geometry 17, a reinforcement structure 40, a guide element 41 and a spring element 18. The latching elements 15 are each arranged centrally on the transverse sides. The latching elements 15 are preferably formed in one piece or monolithically with the immersion tube 12.

The reinforcement structure 40 is plate-shaped. Other shapes for the reinforcement structure 40, such as struts or ribs, are possible. The reinforcement structure 40 is arranged between the collar 23 and the latching geometry 17. The reinforcement structure 40 is connected to the outer surface A ′ and the latching geometry 17. More precisely, the reinforcement structure 40 is stretched between the collar 23 and the latching geometry 17. The reinforcement structure 40 has a slope which increases in the direction of the latching geometry 17.

The reinforcement structure 40 absorbs forces with which the latching element 15 is acted upon during assembly or in the installed state. especially the The locking geometry 17 is relieved by the reinforcement structure 40 and the risk of the locking geometry 17 breaking is reduced.

The locking geometry 17 comprises a cylindrical shape. Alternatively, other shapes, for example polygonal shapes, are possible. The cylindrical latching geometry 17 extends perpendicularly away from the outer surface A '. The latching geometry 17 does not extend further than the collar 23. More precisely, the latching geometry 17 does not protrude beyond the collar 23.

A guide element 41 is arranged on the side of the latching geometry 17 facing away from the collar 23. The guide element 41 is an extension which extends in the direction of the central longitudinal axis of the immersion tube 12 and away from the collar 23. The width of the guide element 41 is smaller than the width of the latching geometry 17. The width here is to be understood as the extent of the guide element 41 in a direction orthogonal to the longitudinal sides.

The guide element 41, in particular the smaller width of the guide element 41, makes it possible to arrange the latching element 15 in a corresponding latching receptacle 16 (cf. Fig. 4 ) simplified.

The spring element 18 of the latching element 15 comprises a slot 19 or a gap. In other words, the spring element 18 is formed by the slot 19. The slot 19 extends essentially along the entire latching element 15. More precisely, the slot 19 extends through the reinforcement structure 40, through the latching geometry 17 and through the guide element 41. The depth of the slot 19 increases linearly in the direction of the reinforcement structure 40. More precisely, the slot 19 begins in the reinforcement structure 40 and deepens in the direction of the guide element 41.

The slot 19 enables the latching element 15 to be compressed. As a result, the latching element 15 can, for example, be compressed so far that the latching geometry 17 can be guided past a constriction or a projection. The locking element 15 can then at least partially return to its original shape. As a result, the locking geometry 17 is arranged behind the projection in a non-positive and / or positive manner. The slot 19 has a in the area of the reinforcement structure 40 shallower depth in order not to impair the reinforcing function of the reinforcement structure 40. The slot 19 is more pronounced in the area of the latching geometry 17 and the guide element 41, since these areas require a certain elasticity in order to be able to be pressed together during assembly.

Support elements 25 are arranged centrally on the outer surface A ′ of the longitudinal sides of the immersion tube 12. The support elements 25 are designed as wings. Alternatively, other shapes, such as ribs or webs, can be implemented. The support elements 25 are connected to the underside of the collar 23 and the outer surface A ′ of the immersion tube 12. The support elements 25 each have a recess on an edge facing away from the collar 23. The function of the support elements 25 is shown below with a view to Fig. 6 received in more detail.

The fluid-conducting areas of the upper part 11 are rounded. This ensures that no residual fluid can remain on any surface and dirt can thus be deposited. The fluid is always discharged essentially completely.

The upper part 11 has two holding means 24. The holding means 24 are each arranged opposite one another on an inner surface of the transverse sides in the funnel-shaped area. The holding means 24 have rounded surfaces and each extend in the direction of the opposing holding means 24 and are inclined upwards away from the immersion tube 12.

The rounded surfaces and the inclination of the holding means 24 are advantageous for the drainage of the fluid and prevent residual fluid from remaining on the surfaces. Furthermore, it is possible to easily remove the odor trap 10 for maintenance by means of the holding means 24.

The Figures 4 and 5 show a lower part 13 of the odor trap 10. The lower part 13 comprises a container 14 which is open at the top. Open at the top means that the container 14 is open at the top in the assembled state. The container 14 is elongated in cross section with longitudinal and transverse sides, the longitudinal sides of the container 14 being straight and the transverse sides being in the shape of an arc of a circle. The upper edge 26 of the container 14 has rounded portions 28.

The rounded upper edge 26 forms a circumferential overflow edge. The encircling overflow edge is advantageous since turbulence in the fluid to be discharged is avoided or reduced in this way. The roundings 28 prevent residues of the fluid to be discharged from sticking.

The container 14 has an inner surface I '. A latching receptacle 16 is arranged in each case on the inner surface I 'of the transverse sides. The latching receptacle 16 comprises two webs 20 which are arranged symmetrically to a plane of symmetry parallel to the longitudinal sides. The webs 20 extend from the upper edge 25 in the direction of the bottom of the container 14. The axial ends of the webs 20 in the region of the upper edge 25 are at a greater distance than the opposite axial ends of the webs 20.

The greater spacing of the webs 20 from one another in the area of the upper edge 25 allows the latching element 15 to be inserted into the latching receptacle 16. The smaller spacing between the opposing axial ends of the webs 20 prevents the upper part 11 from being pushed too far into the lower part 13.

An inner contour 21 is formed between the axial ends of the webs 20. The inner contour 21 corresponds at least in sections to an outer contour 22 of the latching geometry 17 of the latching element 15. Here, the webs 20 are each curved away from one another, so that an inner contour 21 that is essentially circular in sections is formed. The circular inner contour 21 corresponds to the cylindrical shape of the latching geometry 17 or to the latching geometry 17, which is circular in cross section. Starting from the upper edge 25, a constriction is arranged in front of the respective curvature or in front of the inner contour 21. The spacing of the webs 20 from one another in the region of the constriction is smaller than the width of the latching geometry 17.

The locking element 15 is compressed during assembly. The narrowing of the webs 20 is advantageous since the latching geometry 17 is thus arranged in the latching receptacle 16 in a detachable form-fitting and / or force-fitting manner.

A first elevation 42 is arranged centrally on the bottom of the container. The first elevation 42 serves to center the odor trap 10 in a component provided for this purpose during assembly.

Fig. 6 shows the odor trap 10 in the assembled state. The upper part 11 is pushed into the lower part 13 to such an extent that the support elements 25 rests with the recesses on the upper edge 26 and the latching elements 15 are arranged in the latching receptacle 16.

The height of the container 14 corresponds to the height of the barrier fluid column. The barrier fluid column penetrates both the immersion tube 12 and the container 14. The barrier fluid is the fluid that remains in the container 14 and the immersion tube 12 and prevents gases from escaping from the sewer system through the drain.

The support elements 25 form a circumferential gap 27 between the underside of the collar 23 and the upper edge 26 of the container 14. The gap 27 has a height of 8 mm. Depending on the requirements, the gap 27 can be dimensioned differently.

The latching element 15 is arranged in the latching receptacle 16 as described above. More precisely, the latching geometry 17 is arranged in the area between the webs 20, the inner contour of which essentially and / or at least partially corresponds to the outer contour of the latching geometry 17. The constriction prevents the latching element 17 from being removed from the latching receptacle 16 without the action of an external force, and the upper part 11 therefore not being able to be displaced.

The Figures 7, 8 and 9 show a drain pan 30 in which the previously described odor trap 10 can be arranged. The drain pan is open at the top. The side walls 31 of the drainage pot 30 are curved convexly outward along the circumference. In Fig. 9 it can be seen that the side walls 31 are arcuate in cross section. Alternatively, spherical or spherical side walls 31 are possible.

The volume of the drainage pot 30 is increased by the convex curvature. The curvature also improves the flow behavior of the fluid to be discharged. As a result, backwater or overflow of the drain pot 30 can be avoided.

In the area of the opening, the drainage pot 30 has a non-arched section along the circumference. This section has the function that the drain pot can be butt welded.

Anchor elements 35 are arranged on the outside. The anchor elements 35 extend between the opening of the drain pot 30 and its bottom. The anchor elements 35 are designed as beads. Other variants for anchor elements 35, for example ribs or extensions, are conceivable.

The drain pot 30 has two connection areas 32. A connection piece 33 is arranged on a connection area 32. The connection areas 32 have rounded surfaces. In other words, the connection areas have funnel-shaped or conical areas. It is conceivable that the drain pot 30 has up to four connection areas 32 or connection stubs 33.

The funnel-shaped or conical connection areas 32 are advantageous for the flow behavior of the fluid to be discharged. The funnel-shaped connection areas 32 result in less turbulence and the fluid can be discharged more quickly through the connection piece 33.

A second elevation 43 is arranged on the bottom of the drainage pot 30. The second elevation 43 corresponds to the first elevation 42 of the odor trap 10. The odor trap 10 is arranged with the first elevation 42 on the second elevation 43 during assembly. The odor trap 10 is thus centered in the drain pan 30.

Fig. 10 shows an embodiment of a drainage pot 30 with lower side walls 31. Except for the lower side walls 31, the drainage pot 30 essentially corresponds to the embodiment described above. Especially in the embodiment with lower side walls 31, the convex curvature is advantageous because, due to the smaller volume, good drainage behavior is even more important.

The Figures 11a and 11b show a drainage channel 36 to which the in the Figures 7, 8 and 9 shown drain pot 30 is arranged. The drain pan 30 is welded to the drainage channel 36.

End plates 37 are arranged at the axial ends of the drainage channel 36. The end plates 37 are arranged on the side of the drainage channel 36 on which the drainage pot 30 is located. The end plate 37 has an elongated hole 38. The elongated hole 38 extends centrally on the face plate 37 and perpendicular to a longitudinal axis of the drainage channel 36.

The function of the elongated hole 38 is that the face plate 37 can dig into the floor material, for example screed. Furthermore, a stepless height adjustment of the drainage channel 36 is possible through the elongated hole 38. As a result, the drainage channel 36 can be adapted to the level of the ground. Alternatively, it is possible for the end plate 37 to be bent in order to improve the anchor property.

The Figures 12a and 12b essentially correspond to the Figures 11a and 11b . In contrast to the exemplary embodiment described above, the end plate 37 has two elongated holes 38 and a bore 39. The elongated holes 38 are arranged parallel to one another. The bore 39 is arranged below the elongated holes on the central longitudinal axis of the end plate 37.

The bore 39 is advantageous because electrical grounding can be implemented in a simple manner through the bore 39.

The Figures 13a and 13b correspond to the Figures 12a and 12b . and show the exemplary embodiment from FIGS Figures 12a and 12b with the drain pot 30 according to the Figure 10 .
