Field of application

The present application relates to floor drains arranged to be installed in floors of wet rooms. In particular, the present application relates to an interior part that can be installed and removed from a floor drain.

Background

Floor drains are used to drain wastewater from floors and possibly from sewer fixtures connected to the floor drain to the sewer system. The floor drain generally has an interior formed by a body having a sheath and a base forming a bottom cup, and an opening opposite the bottom cup for receiving water to the floor drain, and an interior outlet outlet for removing water from the well. The floor drain may also have a side connection in connection with the interior to receive water to the well, for example from sewage fittings.

The floor drain bottom cup can form a water trap with the outlet pipe 20 inserted inside it, whereby the water remaining in the water trap prevents sewer gases from entering the room. Because of the water trap for long periods of time, especially wastewater, microbial growth and other contaminants may be present and the floor drain needs to be cleaned periodically. As a result, the inner part forming the water trap may be removable for cleaning the inner part and the floor drain.

Detailed explanation

The application discloses an interior part 10 of a floor drain adapted to be placed in a floor drain. By "inner part" is meant in this case the insert 35 in the floor drain and the removable inner part of the floor drain, which together with a suitable floor drain allows the formation of a water trap. The interior can be provided, for example, with a compatible floor drain or as a separate spare.

20165272 prh 13 -01- 2020

Generally, the floor drain 50 comprises an interior compartment formed by a body having a shell 51 and a base 52 forming a bottom cup 53 and an opening 54 opposite the bottom cup to receive water to the floor drain, and an interior outlet 55 to drain water from the well. The sheath forms the walls of 5 floor wells and may be the same as the bottom. The outlet is usually located at a distance from the bottom cup in the floor drain wall, allowing the amount of water to remain in the bottom cup and further creating a water trap. The floor drain has a first end and a second end. The bottom cup when the floor drain is installed at the bottom of the floor drain at one end of the floor drain 10 and is generally smaller in diameter than the largest diameter of the floor drain at the top of the floor well at its first end, i.e., an opening. This end is usually mounted substantially at or slightly below the floor level. A grille can be mounted above this opening. The bottom cup may, for example, have an inside diameter of about 8 to 10 cm. For example, a floor drain may have a maximum inside diameter of about 12 to 14 cm, such as about 13 cm.

Optionally, the floor drain may have one or more interior connections to receive water to the well. The side fittings may be tubular portions detaching from the floor drain 20 to the side to which a drain pipe from a water fixture such as a washing machine, wash basin or the like can be connected. In one example, a floor drain has two side joints that can be parallel. In one example, a floor drain has four side joints, two of which are always parallel and opposite two other side joints.

The inner member 10 has a first end and a second end, one end being the lower end when the inner member is mounted. The inner member comprises a collar 12 defining an opening for receiving water. The collar is generally a circular or substantially circular cylindrical part or rim which is fitted inside the floor well to its first end. The axis or central axis x of the collar or parallel to the first and second ends of the inner member, or the cylinder forming the collar, is generally also the central axis of the inner member. The upper edge of the collar, which forms the first end of the inner part, generally lies at or slightly below the top of the floor drain. The opening for receiving water 35 means the open portion of the interior at its first end, which, in use, points upwards and is generally immediately below the floor drain grille. The collar may have a seal to fit and seal the collar against the floor drain casing. The seal may be in a groove 38 on the outer surface of the collar which:

20165272 prh 13 -01-2020 can rotate the collar in the plane of the flange or parallel to the edge of the first end of the collar. The gasket may be made of an elastic material, for example rubber, and may be in the form of, for example, an O-ring. The seal may have a protruding ridge arranged to abut against the inner walls 5 of the floor drain and to hold the inner member in place. The collar and floor drain casing may also have one or more guide elements 28, for example one or more guides, for example a protrusion, pin, ridge or the like, and a groove, slot or the like arranged thereon to guide and / or support insertion of the interior. The guide element 28 or the second 10 side of the inner part valumalaipan 17 of the outer edge or the part related to it, for example, the groove 38 next to it, or a combination, adapted to fit into the floor drain 50, so that the guide element 28 or the other said part falls on the receiving part, for example the rim, the ridge, the protrusion in the floor drain , a guide element or the like, limiting the penetration of the inner part into the floor drain so that the distance of the outlet pipe from the bottom cup remains suitable for forming a water trap and the inner part does not go too deep into the floor drain.

The collar may also have one or more openings 14 on one or more side joints of the floor drain.

At the other end of the collar 12, at its other end, a casting flange 16, 17 inclined relative to the collar axis x is connected or connected. The slope is arranged to cause water to flow into the drain when the interior is installed in a floor drain. The inclination may be determined, for example, relative to the first end of the collar 12, i.e. the upper edge, or to the collar axis x or normal to this axis, which may be parallel to the collar upper plane or the second end of the outlet tube 20. The angle (a) of the casting flange with the normal x of the collar axis may be in the range 12-30 °, such as 14-20 °, or 14-16 °, for example about 15 °. The pouring flange has a first side 16 or a surface 30 on the side of the collar 12 into which the water entering the floor drain runs, and a second side 17 or a surface located on the side of the outlet pipe 20 and in use on the bottom cup 53. In use, the first side is the upper side and the second side is the lower side.

The drain flange 16, 17 has a drain opening 18 for receiving water. The drainage opening is generally located on the first end of the inner portion, such as the upper edge of the collar 12, on the side of the furthest flange area. This side is the lower side of the drainage flange. The drainage opening is at least substantially offset from the center of the collar or the x axis. The drainage hole may be round or

20165272 prh 13 -01-2020 other shape. In the embodiments shown in the figures, the drainage opening has one straight edge joined by a U-shaped edge, wherein the drainage opening is D-shaped. For example, the straight edge of the opening may be 30-60 mm long, such as about 4050 mm. The opening may also have a diameter of about 30-60 mm in the other direction.

A drainage pipe 20 is connected or connected to a drainage flange 20 on the opposite side of the collar to the drainage port 18 for discharging the flowing water which is arranged to be inserted into the bottom cup 53 of the floor drain 50 to form a water trap. The outlet pipe may have a length in the range of 50-100 mm. 10 Due to the slope of the drainage flange, the length of the drainage pipe may be different across it.

The outlet pipe may have a diameter in the range of 50-80 mm. The shape of the outlet cross-section, i.e. the profile, may be circular or other and may conform to the shape of the spout, for example it may be D-shaped. The end of the outlet pipe, i.e. the other end of the inner portion, is generally perpendicular to the longitudinal direction of the outlet pipe, so that in use it is positioned parallel to the water surface. The outlet, shape, length and diameter are adapted such that, when installed inside the floor drain, the outlet is positioned in the bottom cup, leaving a distance between the outlet and the bottom cup walls and bottom, for example 5-20 mm, to allow a water trap. Thus, in use, water remaining in the bottom cup forms a water trap, but water flow in the water trap is possible.

The diameter of the outlet pipe 20, in particular the inside diameter, is larger than the diameter of the drainage opening 18, so that the edge of the drainage flange forming the edge of the drainage opening forms at least a portion of the opening 22 which may also be called a rim. The protrusion may be substantially in the x-axis of the inner collar 12 or in the center or center region of the pouring flange, allowing the inner member 10 to be lifted from the floor drain by gripping. Substantially in the midpoint range means that the central collar axis x or the center of the casting flange may pass through the protrusion 22, or some portion of the protrusion, or the protrusion or any portion thereof 30 may be close to the center collar x or the center .

The projection 22 formed by the edge of the cast flange may have a depth (a) of 5 to 20 mm, such as 8 to 12 mm, for example about 10 mm. This allows the inside to be gripped by the fingers through the drainage protrusion. Because the protrusion is practically located in or very close to the center axis of the interior, the lifting force is practically directed upwards, whereby the interior rises perpendicularly from the floor level. This prevents the inner part, for example its collar, from wedging

20165272 prh 13 -01-2020 As little force as possible is required against the walls of the floor well and lifting. This reduces the lifting force, especially when the inside is stuck in a floor drain, for example due to impurities. No separate handles or similar separately mounted gripping projections are required, which allows the interior structure to be kept as simple as possible. The inner part containing the gripping part is thus one piece, whereby it can be formed in one casting. This simplifies the fabrication and also the assembly of the final insert. Since the gripping portion is an integral part of the inner part, it is extremely sturdy and cannot under any circumstances detach from the inner part. The accumulation of impurities in the solid part is also low.

The edge of the partial projection 22 or edge formed by the edge of the pouring flange may be straight, preferably 30-60 mm in length (b) at the drain opening, such as 40-50 mm, for example about 45 mm. This further facilitates finger gripping, since such a straight section allows multiple fingers to be used to provide a good grip on the protrusion.

The angle (a) of the drain flange 16, 17 with the normal axis x of the collar may be in the range of 12-30 °, thereby providing effective drainage of water into the drain port 18, while allowing a sufficiently large length of the drain pipe 20. With a greater inclination, the drainage tube would have to be substantially shorter so that the drainage hole and any associated parts would be close to the surface of the water trapped in the trap, increasing the risk of microbial growth in these areas, i.e. virtually liming. When the drain hole and associated parts, such as a non-return valve, are far enough away from the water surface of the water trap, they remain dry and grip on the inside is more hygienic, more comfortable and easier.

In one embodiment, the entire drain aperture 18 is surrounded by a projection 22, 24 or rim formed by the edge of the drain flange. This enables other functionalities and further enhances hygiene. For example, a non-return valve 30, 31 may be provided in the drain opening 18 to close the opening when no water flows into the interior. This prevents odors from the water trap or, if the water trap dries, from the drain.

The inner part, especially for the parts described above, is the same piece. The inner part may be made, for example, by injection molding. The material of the inner part may be, for example, plastic, but other materials are also possible, for example

20165272 prh 13 -01-2020 composite materials such as plastic composites. Examples of suitable plastics include polypropylene, polyethylene, polystyrene, polyethylene terephthalate (PET) and PVC. In one embodiment, the inner member is polypropylene.

In one embodiment, the drainage tube has a hinged non-return valve 30 springed to abut a protrusion 22, 24 formed by an edge of the drainage flange 17 surrounding the drainage opening 18. The non-return valve has a first surface 30 which is seated against a casting flange 17 and a second surface 31 which is on its opposite side.

When the flap 30 is arranged to rest against the surface 17 of the drainage flange, the flap will also be positioned far enough from the surface of the water in the water trap so that the flap will remain clean and free of growth than it would be lower in the interior.

In one embodiment, the non-return valve 30 is hinged, preferably by hinge pins 32, directly to the inner body, preferably in the region of the connection between the drain flange 17 and the drain pipe 20, such as the drain surface 17 or the inner surface of the drain pipe 20. This simplifies the structure and assembly of the interior.

Changing the flap is also easy, especially when compared to a structure in which the flap is hinged to a separate inner part to be installed in the exhaust pipe, which is difficult to remove, especially from a long-term soiled interior. The back flap hinged to the inner body may have shaft pins 32 for engaging it with corresponding counterparts 26 on the inside. no pressure applied. The rigidity of the spring member is arranged such that the flap is adapted to open to the interior by the weight of the water flowing. Such a detachable non-return valve 30 may be offered for sale separately as a spare part and is easily replaceable in the interior.

The gasket 34 may be provided on the surface of the non-return valve 30 to rest against a protrusion formed by the edge of the casting flange, such as a fixed gasket, preferably a gasket glued to the flap 35. A fixed gasket is a gasket which is fixed against the flap, i.e. the gasket does not contribute to any part of the flap. For example, the seal may be a strip 34, preferably 4 to 7 mm wide, at the edges of the drain flange at the edges of the return flap 30. Such a gasket is lightweight and due to the gluing there is no need to make holes or the like in the back flap for mounting the gasket. The seal may be made of an elastic material, for example an elastomer such as rubber.

The interior may also have other components, for example, the splash guard shown in the figures as covering one or more side portions of the floor drain of any one or more openings. The splash guard may have an opening at the spout so that it does not block the flow of water from the side joints to the spout. The splash guard prevents water coming from the side connection from being pressurized from the floor drain.

The insert is intended to be placed in a compatible floor drain, resulting in an arrangement and arrangement of the interior and the floor drain itself.

One embodiment provides a floor drain 50 which comprises

an interior space formed by a body having a sheath 51 and a base 52 forming a bottom cup 53 and an opening 54 opposite the bottom cup for receiving water into the floor drain,

an inlet connection 55 for removing water from a floor well, and

The inner part 10 is arranged to be positioned inside the floor well 50 so that the outlet pipe 20 and the bottom cup 53 form a functioning water trap. The floor drain 50 may further comprise one or more side ports communicating with the interior to receive water to the floor drain.

The inside of the floor drain and the arrangement of the floor drain will now be described with reference to the exemplary embodiment shown in the figures.

Example

Figure 1 shows an exemplary floor drain insert 10 having a cylindrical collar 12 with a diameter of about 13 cm at the first end 5 of the insert and an associated inclined pouring flange having a first surface 16 visible. The inside height is 103 mm. The collar 12 has two openings for the side joints of the 14 floor wells. Due to the slope of the casting flange, the collar height varies from 11.05 to 40.50 mm across the collar. The drainage flange has a drainage opening 18 for water which is located in the portion of the drainage flange 10 which is furthest from the first end of the inner part, i.e. the upper edge of the collar 12.

The drainage opening is straight on one side and otherwise curved, i.e. D-shaped. The drainage opening does not extend all the way to the collar 12 on the side of the openings 14, but even closes at a distance of about 10 mm from the collar. The pouring flange also has two protrusions 19 for securing a separately mounted splash guard 36.

Figure 2 shows the inside of the floor drain 10 as seen from the bottom, showing the outlet pipe 20 connected to the second surface 17 of the drain flange, which is located at the drain opening 18. The diameter (61 mm x 68 mm) of the outlet pipe 20 is larger than the diameter of the spout 18 so that the edge 20 of the spout flange 17 adjoining the spout 18 forms a protrusion 22 having a depth (a) of about 10 mm. The protrusion at the spout (b) is approximately 46 mm and is mostly straight.

At the edge of the collar, there is a slot 28 for aligning and securing the inner part to a floor drain having a corresponding counter piece for the slot. Hahlo locks the inside into the desired position in the floor drain.

Figure 3 shows the inside 10 of the floor drain directly below, or from the other end of the inside, viewed from below. The figure shows that the drainage flange 17 forms on the inside of the drainage pipe 20 a rim 22, 24 or a protrusion around the entire drainage opening 18. The straight portion 22 has a greater depth (about 10 to 30 mm) than the curved portion 24 (about 5 mm). At the junction of the drain flange 17 and the outlet pipe 20, two counterparts 26 are formed for the hinge pins of the non-return valve.

Figure 4 shows the inside 10 of the floor drain as seen from the top and the non-return valve 35 30, 31 mounted. The first flap surface 30, which abuts against the second surface of the casting flange 17, has a flap-sealed rubber seal 34 which wraps the flap edges in the form of a band.

20165272 prh 13 -01- 2020

Fig. 5 shows the same embodiment below the inner part 10, where the hinge pins 32 of the non-return flap 30, 31 are mounted on the counterparts 24. The spring member is not shown but would lie against the second surface 31 of the flap and the inner surface of the outlet pipe 20.

Fig. 6 is a side sectional view of the flared insert 10. The splash guard 36 is mounted and covers the side port openings 14. The collar 12 rotates a groove 38 in the plane of the spout flange 16, 17 where a seal can be mounted. The figure also shows the central axis x of the collar, which passes through the projection 22 of the opening 10, i.e. the edge of the casting flange. When the projection 22 is gripped with the inner member 10, the inner member can be lifted axially out of the floor drain. The figure shows the inclination (a) of the drain flange at 14.6 ° relative to the collar axis x normal which is parallel to the first edge or top edge of the collar 12, or to the bottom 15 of the outlet pipe 20.

Fig. 7 shows a non-return valve as seen from the side of its first surface 30. The first surface is glued with a strip-like rubber gasket 34 extending 5 mm wide along the flap edges. There are two shaft pins 20 32 on the straight edge of the flap, which are intended to be secured to respective counterparts 26 on the inside of the outlet pipe. A shaped spring 40 made of steel wire is mounted on a corresponding shaft pin between the actual shaft pins 32 for flap actuation. From Fig. 8, it can be seen that the spring has a helical portion which divides the first elongated portion located against the second surface 31 of the flap and a second elongated portion located against the wall of the outlet pipe.

Figure 9 is a cross-sectional view of an exemplary floor drain interior mounted to an exemplary floor drain 50. The collar 12 of the interior fits snugly close to the opening 54 of the floor drain casing 51, thereby sealing the interior into the floor drain (seal).

the second side of the inner part valumalaipan 17 of the outer edge of the floor drain shell 51 of the receiving part, the inner part of the exhaust pipe 20 is set 53 so that there is a space 20 between the second end of the bottom 52 and the exhaust pipe and the exhaust pipe and the drain of the sheath 51 the drain bottom cup in which the water can flow 35 through the drain to the outlet 55, and where a water trap may be formed.

The other end of the outlet pipe 20 is thus below the bottom edge of the outlet connection 55, i.e. the bottom side of the bottom cup, i.e. the bottom of the bottom cup.

The draft flange protrusion 22 is also located at the center axis of the opening 54 of the floor drain 50, so that when lifting the inner part out of the projection, the inner part rises straight up from the floor well, requiring minimal force to lift it.
