    Insert for floor drain and floor drain Field of application The present application relates to floor drains configured to be installed in the floors of wet rooms. The present application relates specifically to an insert which can be installed in and removed from a floor drain.
    Background Floor drains are used for leading waste water from floors, and possibly from drainage fittings connected to the floor drain, into the sewer system. A floor drain usually has an interior formed by a body comprising a casing and a base, which form a base cup, and opposite the base cup an opening for receiving water into the floor drain, and a discharge fitting connected to the interior for discharging water from the drain. The floor drain may also comprise a side fitting connected to the interior for receiving water into the drain, for example, from the drainage fittings.
    The base cup of the floor drain may form a drain trap with the discharge pipe in the insert placed in the cup, whereupon the water remaining in the drain trap prevents sewer gases from rising into the room. Since water, especially waste water, stands in the drain trap for long periods of time, microflora and other impurities may appear in the drain trap and the floor drain must be cleaned from time to time. Because of this, the insert forming the drain trap may be removable for the purpose of cleaning the insert and the floor drain. If the floor drain insert includes a relief valve which prevents air or liquid from flowing or splashing from the insert, especially this type of structure may accumulate impurities and be difficult to clean or maintain. The relief valve is usually installed inside the discharge pipe from below, which means that it is difficult and unhygienic to detach and requires that the floor drain insert is removed from the floor drain.
    Brief summary The present application discloses an insert 10 for a floor drain, which insert is configured to be placed in a floor drain, the floor drain comprising - an interior formed by a body comprising a casing and a base which form a base cup, and opposite the base cup an opening for receiving water into the floor drain, and - a discharge fitting connected to the interior for discharging water from the floor drain, the insert comprising - a collar 12 which defines the opening for receiving water, - a drainage flange 16 connected to the inner surface of the collar 12, the flange being inclined with respect to the axis (x) of the collar, - a drainage aperture 18 in the drainage flange 16, 17, - a discharge pipe 20 connected to the drainage flange at the drainage aperture 18 on the opposite side 17 with respect to the collar for discharging the flowing water, the said discharge pipe being configured to be placed in the base cup of the floor drain to form a drain trap, wherein - in the drainage aperture 18 is a relief valve frame 36 configured to be placed removably in the drainage aperture from the collar 12 side, on the discharge pipe side of which frame is hinged a relief valve 30, which is suspended to settle against the frame 36 of the relief valve in order to close the discharge aperture 18.
    The present application also discloses a floor drain 50 comprising - an interior formed by a body comprising a casing 51 and a base 52 which form a base cup 53, and opposite the base cup an opening 54 for receiving water into the floor drain, - a discharge fitting 55 connected to the interior for discharging water from the floor drain, and - an insert 10, as described herein, placed in the interior of the floor drain.
    The floor drain insert described herein is easy to remove from the floor drain, thus facilitating the cleaning and maintenance of the floor drain. The structure of the insert helps to keep it free from microflora, which means that there is little slime formation especially on the insert and its parts. In the insert may be or is removably fixed a relief valve for closing the drainage aperture when water is not flowing in the insert. This prevents odour formation from the drain trap, or the sewer if the drain trap should dry out.
    Especially a relief valve located in the insert of a floor drain is detachable from the floor drain through the top end without removing the floor drain insert itself, which allows easy cleaning or maintenance of the insert and the floor drain. The relief valve is easy to replace or maintain without removing the entire floor drain insert from its place. Furthermore, since the relief valve is at the top end of the discharge pipe, it is in as little contact as possible with the water in the floor drain, which reduces its soiling substantially.
    Although the relief valve is easy to detach, keeping it closed during use is ensured by the solutions described herein, such as by means of projections fitted in holes in the frame of the relief valve, and through the design of the splash guard in the interior of the floor drain. In the solution described herein, a splash guard which is conventional as such, is designed in such a way that its parts settle above the frame of the relief valve so that the relief valve cannot rise upwards from its place.

    Detailed description The present application discloses an insert 10 for a floor drain configured to be placed in a floor drain. In this connection, "insert" refers to an insert for a floor drain which can be installed in the floor drain and removed from it, which together with a suitable floor drain allows the formation of a drain trap. The insert may be provided, for example, together with a compatible floor drain or as a separate spare part. The insert is described in the following with reference to the accompanying Figures 1 to 8, which show illustrative examples of embodiments of the floor drain insert.
    A floor drain 50 usually comprises an interior formed by a body comprising a casing 51 and a base 52 which form a base cup 53, and opposite the base cup an opening 54 for receiving water into the floor drain, and a discharge fitting 55 connected to the interior for discharging water from the drain (Fig. 9). The casing forms the walls of the floor drain and it may be of the same piece with the base. The discharge fitting is usually at a distance from the base cup, on the wall of the floor drain, which allows an amount of water to remain in the base cup and further the formation of a drain trap. The floor drain has a first end and a second end. When the floor drain is installed, the base cup is at the bottom of the floor drain, at the second end of the floor drain, and its diameter is usually smaller than the largest diameter of the floor drain, which is in the upper part of the floor drain, at its first end, that is, at the end with the opening for receiving water into the floor drain. This end is usually installed essentially at floor surface level or slightly below it. Above this opening may be installed a grating. The inside diameter of the base cup may be, for example, approximately 8 to 10 cm. The largest inside diameter of the floor drain may be, for example, approximately 12 to 14 cm, such as approximately 13 cm.
    The insert 10 has a first end and a second end, the second end being the lower end when the insert is installed in the floor drain. The insert comprises a collar 12 which defines the opening for receiving water (Fig. 1). The collar is usually a round or essentially round cylindrical part or edging which is fitted inside the floor drain, to fit its first end. Through the midpoint of the collar, parallel with the first and second end of the insert, runs an axis or central axis x of the collar, or of the cylinder forming the collar, the said axis usually also being the central axis of the insert (Fig. 6). The upper edge of the collar, which forms the first end of the insert, usually settles on the level of the upper edge of the floor drain or slightly below it. The opening for receiving water refers to an open part of the insert at its first end, which points upwards in use and is usually immediately below the floor drain grating. The collar may have a gasket 39 for fitting and sealing the collar against the casing of the floor drain. The gasket may be in a groove 38 on the outer surface of the collar, which groove may encircle the collar on the drainage flange level or parallel with the edge of the first end of the collar. The gasket may be of an elastic material, for example rubber or silicone, and it may be, for example, in the shape of an O-ring. The gasket may have a protruding ridge which is arranged to settle against the inner walls of the floor drain and to keep the insert in place. The collar and the floor drain casing may also have one or more guide elements, for example, one or more guides, such as a protrusion, a peg, a ridge or the like, and a groove, a slot or the like fitted to it, which are arranged to guide and/or support the settling of the insert in the floor drain. The guide element or the outer edge of the second side 17 of the drainage flange of the insert or a part connected to it, for example adjacent to the groove 38, or these together, are configured to settle in the floor drain 50 in such a way that the guide element 28 or other said part meets a receiving part in the floor drain, for example an edging, a ridge, a projection, a guide element or the like, thus limiting the penetration of the insert in the floor drain, such that the distance of the discharge pipe from the base cup remains suitable for forming the drain trap and the insert will not go too deep into the floor drain.
    The collar may also have one or more openings 26. These may be covered by a splash guard 15 or a splashboard which may have, for example, a curved outer surface, as shown in Figure 2. The splashboard may be detachable and replaceable.
    On the inner surface of the collar 12, at its second end, connects or is connected a drainage flange 16, 17 which is inclined with respect to axis x of the collar (Fig. 6). The inclination is arranged to be such that it causes water to flow into a drainage aperture when the insert is installed in the floor drain. The inclination may be determined, for example, with respect to the first end, that is, the upper edge of the collar 12, or axis x of the collar or the normal of this axis, which may be parallel with the plane of the upper edge of the collar or the second end of the discharge pipe 20. The angle (a) of the drainage flange with the normal of the axis x of the collar may be within the range from 12° to 30°, such as 14° to 20°, or 14° to 16°, for example, approximately 15°. The drainage flange has a first side 16 or first surface which is on the side of the collar 12 and onto which the water entering the floor drain flows, and a second side 17 or second surface which is on the discharge pipe 20 side and in the use on the base cup 53 side. In use, the first side is the upper side and the second side is the lower side.
    The drainage flange 16, 17 has a drainage aperture 18 for receiving water. The drainage aperture is usually on the side of the drainage flange area furthest away from the first end of the insert, such as the upper edge of the collar 12. In use, this side is the side of the drainage flange which remains lower. The drainage aperture is at least for the most part to the side of the midpoint of the collar or of axis x. The drainage aperture may be round or of a different shape. In the embodiments shown in the Figures, the drainage aperture has one straight edge connected to a U-shaped edge, which make the drainage aperture D-shaped. In this case, the straight edge is closest to the central axis x of the collar and facilitates the implementation of hinging on the relief valve. The edge closest to the central axis of the drainage aperture, such as a straight edge, may run at a distance of 5 to 15 mm from the central axis x, such as at distance of 10 to 12 mm. The straight edge of the aperture may be, for example, 30 to 60 mm long, such as approximately 40 to 50 mm long. The diameter of the aperture may be approximately 30 to 60 mm also in another direction.
    A discharge pipe 20 connects to is connected to the drainage flange at the drainage aperture 18, on the opposite side 17 with respect to the collar, for discharging the flowing water, the said discharge pipe being configured to be placed in the base cup 53 of the floor drain 50 to form a drain trap. The length of the discharge pipe may be within the range from 50 to 100 mm. Due to the inclination of the drainage flange, the length of the discharge pipe may differ on its different sides. The diameter of the discharge pipe may be within the range from 50 to 80 mm. The shape of the section of the discharge pipe, that is, its profile, may be round or a different shape, and it may imitate the shape of the drainage aperture, for example, it may be D-shaped. The end of the discharge pipe, that is, the second end of the insert, is usually perpendicular to the longitudinal direction of the discharge pipe, in which case it settles parallel to the surface of the water in use. The shape, length and diameter of the discharge pipe are configured to be such that when the insert is installed in the floor drain, the discharge pipe settles in the base cup in such a way that between the discharge pipe and the walls and bottom of the base cup remains a distance, for example, 5 to 20 mm, which makes the formation of a drain trap possible. In use, the water remaining in the base cup thus forms a drain trap, but the flow of water in the drain trap is possible.
    In the drainage aperture 18 of the present floor drain is a relief valve frame 36 configured to be removably placed in the drainage aperture from the collar 12 side, on the discharge pipe side of which frame is hinged a relief valve 30, which is suspended to settle against the frame 36 of the relief valve in order to close the discharge aperture 18. The relief valve has a first surface 30, which settles against the frame 36, and a second surface 31 , which is on its opposite side. The frame may be detached from and/or correspondingly be placed back in the position designed for it in the drainage opening by using manual force. The user can, therefore, replace the relief valve or a part of it manually, without tools, or detach the valve with its frame for maintenance, replacement or cleaning without removing the insert itself from the floor drain.
    When the relief valve 30 is arranged to settle against the frame 36, the valve will also settle far enough from the surface of the water in the drain trap, whereupon the valve will remain clean and free of growth better than if it was lower down in the insert.
    The relief valve may have shaft journals 32 for connecting it with hinges to the corresponding counterparts in the frame, in practice holes 40. The shaft journals may be on the second surface 31 of the relief valve, for example, connected to it with a connecting piece, as shown in Figure 8. The relief valve is connected with springs, that is, it may include a spring means 40, for example, a spring bent into shape from steel wire or the like, or other elastic piece, which is arranged to return the valve against the frame when no pressure is exerted on the valve. The rigidity of the spring means is arranged to be such that the valve is configured to open by the weight of the water flowing into the insert. The relief valve, or the relief valve with its frame, or its spring means, may be offered for sale as a separate spare part and it is easy to replace in the insert.
    The hinging may be essentially in the area of axis x of the collar 12 of the insert or in the area of the midpoint or central part of the drainage flange, thus allowing the relief valve with its frame to be lifted directly upwards from the floor drain by gripping the frame. Essentially in the midpoint area means that the central axis x of the collar or the midpoint of the drainage flange may pass through the hinging, or through a part of the hinging, such as the shaft or spring of a shaft journal or shaft journals, or the hinging or its part may be close to the central axis x of the collar or the midpoint of the drainage flange, for example, at a maximum distance of 10 mm or 5 mm. In one example, the relief valve 30 is hinged to the frame 36 of the relief valve in such a way that when the frame is installed in the drainage aperture, the hinging settles in the central axis x area of the collar or in its vicinity, as described above.
    On the surface of the relief valve 30 may be a gasket 34, such as a fixed gasket, preferably a gasket glued to the relief valve, arranged to settle, for example, against the edging on the frame 36, preferably the first edging 37. A fixed gasket is a gasket which is fixedly against the valve, that is, no part of the gasket is detached from the valve. The gasket may be, for example, a strip 34, preferably having a width of 4 to 7 mm, which settles at the projections formed by the edge 37 of the drainage flange on the edges of the relief valve 30. This type of gasket is light, and due to the gluing, no holes or the like need to be made in the relief valve for installing the gasket. The gasket may be made of an elastic material, for example an elastomer, such as rubber, or silicone.
    The diameter of the discharge pipe 20, especially its inner diameter, may be the size of the diameter of the drainage aperture 18, or slightly smaller than its diameter, for example 1 to 3 mm smaller. The diameter of the discharge pipe extending from the surface 16 of the drainage flange may be configured to receive the frame 36 of the relief valve at a height of, for example, approximately 3 to 10 mm, after which the inner diameter may be smaller up to its other end. A recess 14 arranged to receive the frame 36 of the relief valve may, therefore, encircle the inner surface of the discharge pipe, starting directly from the surface 16.
    In one embodiment, the relief valve frame 36 includes a surface configured to settle on the surface 16 of the drainage flange, the surface forming an edging 37 surrounding the drainage aperture, against which edging the relief valve 30 is configured to settle. The upper surface of the frame and the upper surface of the drainage flange are, therefore, on the same level as the relief valve frame when the relief valve frame is installed in place. From Figures 3 and 4 can be seen how the relief valve frame 36, especially its edging 37 (Fig. 7), settles on the level of the surface 16 of the drainage flange, which facilitates the flow of water into the drainage aperture 18. Due to the edging 37 encircling it, the drainage aperture closed by the valve 30 and formed by the frame 36 is smaller than the actual discharge aperture 18 opening into the discharge pipe 20. This edging can also be called the first edging 37. The width of the edging 37 encircling the drainage aperture of the frame may be, for example, 2 to 15 mm or 4 to 12 mm. The width of the edging may be different on different sides of the frame. For example, in the example of Figure 7, the edging 37 is widest on that side of the frame on which the relief valve is hinged, for example approximately 12 mm at the widest point, which may form the straight section of the frame, and approximately 4 mm at the narrowest point, which may form the curved section of the frame. The frame may include a second edging 35 protruding perpendicularly from the edging, the second edging being on the relief valve side and surrounding it, and to which the relief valve may be hinged, for example, with shaft journals 32 in the holes 40 on the second edging 35. The second edging 35 settles against the inner walls of the discharge aperture 18, preferably at the point 14 designed for it, which may thus be slightly wider in its inner diameter than the rest of the discharge aperture.
    The angle (a) of the drainage flange 16, 17 with the normal of axis x of the collar may be within the range from 12° to 30°, whereby an efficient flow of water into the drainage aperture 18 is achieved, but at the same time a sufficient length of the discharge pipe 20 is made possible. With a greater inclination, the discharge pipe would have to be essentially shorter, in which case the drainage aperture and the parts possibly connected to it would be close to the surface of the water remaining in the drain trap, which increases the risk of microflora in these areas, that is, in practice slime formation. When the drainage aperture and the parts relating to it, such as the relief valve, are far enough from the surface of the water in the drain trap, they will remain dry and gripping the insert is more hygienic, more pleasant and easier.
    The insert may be of the same piece, especially as regards the parts described above. The insert may be made, for example, by injection moulding. The material of the insert may be, for example, plastic, but other materials are also viable, for example, composite materials such as plastic composites. Examples of suitable plastics are polypropylene, polyethylene, polystyrene, polyethylene terephthalate (PET) and PVC. In one embodiment the insert is polypropylene.
    The insert may also include other parts, for example a splash guard 15, as shown in the Figures, as cover for one or more side fittings of a floor drain with one or more potential apertures. The splash guard may have an opening at the drainage aperture, in which case it will not prevent the flow of water from the side fittings into the drainage aperture. The splash guard prevents the water coming from the side fitting, possibly under pressure, from splashing from the floor drain. The insert is intended to be placed in a compatible floor drain, whereby an arrangement and an assembly formed by the insert and the actual floor drain is obtained. The floor drain insert may also include a handle for lifting the insert out of the floor drain, for example, a handle 13 hinged on the first surface 16 of the drainage flange.
    In one embodiment there is a splash guard 15 on the collar side surface 16 of the drainage flange, of which splash guard at least a part 24, 25 is configured to settle on the frame 36 of the relief valve. Figures 1 and 4 show a splash guard 15 installed in place on two protrusions 19 on the surface of the drainage flange 16 and supported on the inner wall of the collar 12. The splash guard has specifically at least one part which is configured to settle on the frame of the relief valve when the splash guard is in place, whereupon the frame is unable to rise up from its installed location. In the example of Figure 4, the splash guard has two corners 24, 25 which settle above the edges of the relief valve frame on the surface of the drainage flange in such a way that the splash guard is in contact with or presses the edges of the frame, or in between remains only a very small gap, such as less than 1 mm, for example, 0.2 to 1 mm, such as 0.2 to 0.5 mm or 0.5 to 1 mm. The splash guard is detachable, which means that it can be removed to gain access to the relief valve.
    A different solution may also be applied to ensure that the relief valve and its frame remain attached. In one embodiment, the relief valve has shaft journals 32 by means of which it is hinged in holes 40 passing through the relief valve frame 36 in such a way that the shaft journals 32 do not extend completely through the holes 40, and wherein in the drainage aperture 18 are projections 22 configured to settle in the holes for locking the relief valve frame 36 in place in the drainage aperture. The holes fitted in the projections may also be other holes or recesses in the relief valve frame, especially in the second frame 35. The projections 22 may be, for example, nodule- or peg-like. Their projection from the plane of the drainage aperture may be relatively small, such as 0.5 to 2 mm, for example 0.5 to 1 mm. The diameter of the projections may be, for example, 2 to 3 mm. If the projections settle in the same holes 40 in the frame 36, 35 in which the hinge pins 32 already are, the projections also help to stabilise the relief valve 30 in the frame by preventing the movement of the valve in the holes of the frame in the direction of the axis of the hinge pins.
    The material of the floor drain insert 10 and preferably of the relief valve frame 36 and the relief valve 30 may be plastic, such as a plastic selected from the group of polypropylene, polyethylene, polystyrene, polyethylene terephthalate (PET) and PVC, preferably polypropylene.
    One embodiment provides a floor drain 50 which comprises - an interior formed by a body comprising a casing 51 and a base 52 which form a base cup 53, and opposite the base cup an opening 54 for receiving water into the floor drain, - a discharge fitting 55 connected to the interior for discharging water from the floor drain, and - an insert 10 placed in the interior of the floor drain. The insert 10 is configured to settle in the interior of the floor drain 50 such that the discharge pipe 20 and the base cup 53 form a functioning drain trap. The floor drain 50 may further comprise one or more side fittings connected to the interior for receiving water into the floor drain.
    The insert for the floor drain and the arrangement in the floor drain are described in the following with reference to an illustrative implementation shown in the Figures.
    Example Figures 1 and 2 show an insert 10 for a floor drain according to an example, wherein at the first end of the insert is a cylindrical collar 12 having a diameter of approximately 13 cm and an inclined drainage flange connected to it and with its first surface visible 16. The height of the interior is 103 mm. Due to the inclination of the drainage flange, the height of the collar is different on different sides of the collar and it is within the range from 11.05 to 40.50 mm. The drainage flange has a drainage aperture 18 for water, which aperture is located in a part of the drainage flange which is furthest away from the first end of the insert, that is, from the upper edge of the collar 12. The drainage aperture is straight on one side and otherwise curved, that is, D-shaped. The drainage aperture does not reach all the way to the collar 12 on the side of the openings 14, but remains even at closest at a distance of approximately 10 mm from the collar. The drainage flange also has two elongated protrusions 19 for fixing a separately installed splash guard 15.
    Figure 2 shows a discharge pipe 20 connected to the second surface 17 of the drainage flange, the discharge pipe being at the discharge aperture 18. The diameter (59 mm x 64 mm) of the discharge pipe 20 is slightly smaller than the diameter of the drainage aperture 18 because at the top end of the discharge pipe is formed a widening 14 for the relief valve frame 36, 35. In Figure 2, the splash guard is set in place and rests on the protrusions 19. To the insert is also connected a hinged handle 13 for lifting the insert from the floor drain.
    In Figure 3, the relief valve 30 with its frame are installed in place in the floor drain insert. In Figure 4, a splash guard 15 is also installed in place in the floor drain insert, the splash guard ensuring that the relief valve frame 36 remains in its opening by means of the shaped corners 24, 25 of the splash guard, the said corners preventing the relief valve frame 36 from rising up from its place.
    Figure 5 shows the floor drain insert 10 as seen directly from below, from the second surface 17 side of the drainage flange, or from the second end side of the insert. The Figure shows that the relief valve is hinged to the frame 36 with shaft journals 32 and supported with a spring 40 on the discharge pipe 20.
    Figure 6 shows a cross-section of the insert 10 with a valve as seen from the side. The splash guard 15 is installed in place. The collar 12 is encircled on the drainage flange 16, 17 surface by a groove 38 in which is installed a gasket 39. The Figure also shows the central axis x of the collar which runs through the hinging of the relief valve. The Figure shows the inclination (a) 14.6° of the drainage flange with respect to the normal of axis x of the collar, the normal being parallel with the level of the first edge or upper edge of the collar 12, or the level of the lower edge of the discharge pipe 20.
    Figure 7 shows the relief valve as seen from the side of its first surface 30. On the first surface is glued a band-like, 5 mm wide rubber gasket 34 which follows the edges of the valve. On the straight edge side of the valve are two shaft journals 32 which are placed in corresponding holes 40 on the other edging 35 of the frame 36. Figure 8 shows the relief valve as seen from the side of its second surface 31 . A formed spring 40 made of steel wire is installed on a corresponding shaft journal between the actual shaft journals 32 intended for installing shafts in the valve. In Figure 8 can be seen that the spring has a part made into a spiral from which diverges a first elongated part that settles against the second surface 31 of the valve, and a second elongated part that settles against the wall of the discharge pipe.
    Figure 9 shows a cross-section of an illustrative example of a floor drain 50. When installed, the collar 12 of the insert settles tightly to the end near the opening 54 of the casing 51 of the floor drain, whereupon the gasket in the groove 38 of the insert seals the insert to the floor drain. The outer edge of the second side 17 of the drainage flange of the insert meets the receiving part in the casing 51 of the floor drain, whereupon the discharge pipe 20 of the insert settles in the base cup 53 of the floor drain such that between the base 52 and the second end of the discharge pipe 20 and the discharge pipe and the floor drain casing 51 remains a space in which water can flow through the floor drain into the discharge fitting 55, and in which a drain trap may be formed. The second end of the discharge pipe 20 is thus below the lower edge of the discharge fitting 55, that is, below the base cup side edge, in other words on the base cup side.
