DRAINAGE DEVICE

Description

[0001] The invention relates to a drainage device according to claim 1.

[0002] A variety of drainage systems for discharging wastewater are known. One problem with previously known drainage systems is that wastewater collects or remains on various surfaces of the drainage system, particularly on a support surface for a cover element. Wastewater that remains on the surfaces for a longer period of time evaporates instead of flowing away. This increases the humidity, and the evaporated wastewater leaves behind dirt residues on the surfaces of the drainage system. This leads to increased cleaning effort and increased cleaning costs. In addition, bacteria multiply very quickly in the wastewater that remains on the surfaces. This endangers the health of people who come into contact with the wastewater remaining on the surfaces or who inhale the wastewater that evaporates after some time.

[0003] SE 306 062 B describes a drain system with a stepped wall. Furthermore, a grating is arranged on the drain system, which is flush with the upper edge of the wall.

[0004] US 2 898 129 A describes a drainage device with a flange to which a waterproof membrane or a connection is attached by means of a clamping ring.

[0005] Document FR 2 296 113 A describes a trough-type siphon, in particular a drainage shaft with an inlet, an outlet manifold and a check valve.

[0006] US 4,462,123 describes a floor drain that is designed to retain objects, particularly washed-up garbage, and only allow the (waste) water to drain away.

[0007] DE 1 979 590 U describes a floor siphon consisting of a bowl equipped with a drainpipe and a vertical insert nozzle opening below the lower edge of the drainpipe near the bottom of the bowl. US 4,562,602 describes a wide floor drain adapted to a narrow drainpipe and including a wide drain body with an upper flange extending radially outward from its upper end and positioned flush with a floor surface.

[0008] US 2007 / 0177942 A1 discloses a floor drain with a drain pan and a grate inserted into the drain pan. A pipe is connected to the drain pan to drain surface water. The drain pan has a horizontal bar with upwardly oriented support elements to support the grate.

[0009] The invention is based on the object of demonstrating a drainage device in which it is technically simple to prevent wastewater from remaining on (surface) surfaces of the drainage device or from remaining there for a longer period of time.

[0010] This object is achieved by a drainage device according to claim 1. In particular, the object is achieved by a drainage device for discharging wastewater, comprising an upper edge surface which forms an outer perimeter of the drainage device, a support surface for supporting a cover element such that its walkable surface runs substantially flush with the upper edge surface, and a base for collecting and for conveying wastewater into an opening of a drain nozzle in the base of the drainage device, wherein the upper edge surface, the support surface and the base are connected to one another via connecting walls which run substantially vertically during use.

[0011] According to the invention, at least a portion of the support surface is configured to slope downwards toward the floor such that, during use, wastewater that reaches the support surface flows downwards. Furthermore, the floor comprises a plurality of floor elements that are inclined at an angle toward one another and slope downwards toward the opening of the drain outlet, with the floor elements being connected to one another via connecting edges. One advantage of this is that wastewater that reaches the various floor elements is reliably guided to the opening of the drain outlet. Furthermore, the connecting edges between the floor elements of the floor are each aligned perpendicular to one another when viewed from above.

[0012] A key point of the invention is that at least part of the support surface for supporting the cover element is designed to slope downwards towards the ground. This means that at least part of the support surface is inclined relative to the horizontal during use in such a way that water flows away or is diverted towards the ground and thus towards the opening of the drain nozzle. One advantage of this is that the wastewater flows away from the support surface of the drainage device in a technically simple, reliable and rapid manner. This prevents wastewater from accumulating on the support surface or from remaining there and evaporating, whereby residues of the evaporated wastewater accumulate on the support surface. This reduces the cleaning effort and costs. In addition, the proliferation of bacteria, which multiply rapidly in (warm) wastewater, is prevented or reduced on the drainage device.suppressed because no wastewater remains on the support surface (longer).

[0013] In one embodiment, the upper edge surface is designed to slope at least partially towards the ground such that, during use, wastewater that reaches the upper edge surface flows away towards the ground. This further prevents the accumulation or retention of wastewater on the upper edge surface. In addition, the formation or accumulation of residues from evaporated water on the upper edge surface is essentially prevented in a technically simple manner. This makes keeping the drainage system clean or cleaning it much easier. This leads to less cleaning effort and lower cleaning costs. Furthermore, the risk of slipping is reduced when a person steps on the drainage system or the upper edge surface, as friction is increased by the safe drainage of the wastewater from the upper edge surface. No wastewater remains on the upper edge surface that could act as a slip film.

[0014] In a further embodiment, at least some of the outer edges bordering the support surface, in particular all outer edges bordering the support surface, are rounded. This ensures even more reliable drainage of wastewater. Furthermore, the retention of wastewater on surfaces of the drainage system is further prevented. This makes it even more difficult for residues of evaporated wastewater to form or accumulate on the drainage system or surfaces of the drainage system. Furthermore, cleaning the support surface is facilitated.

[0015] At least some of the outer edges bordering the floor, in particular all outer edges bordering the floor, can be rounded. This further prevents wastewater from accumulating or remaining on the surfaces of the drainage system. It also makes cleaning the floor easier.

[0016] According to the invention, at least a portion of the floor is designed to slope downwards toward the opening of the drain outlet. This supports and reliably ensures the drainage of water from the floor into the opening of the drain outlet. This more reliably prevents wastewater from remaining on parts of the floor. Thus, residues of evaporated water are less likely to remain on parts of the floor. This reduces cleaning effort and also lowers cleaning costs.

[0017] All surfaces of the drainage system intended for contact with wastewater can be designed to slope downwards toward the opening of the drain outlet. This allows for a technically simple drainage system that essentially prevents wastewater from accumulating or remaining on any surface of the drainage system. This prevents dirt residues from evaporated wastewater from accumulating or forming on the surfaces of the drainage system. This significantly reduces cleaning effort and costs. Furthermore, cleaning the surfaces is made easier. Furthermore, bacterial proliferation is suppressed.

[0018] In a further embodiment, the base has reinforced areas where the base has a greater thickness compared to the areas of the base outside the reinforced areas. One advantage of this is that the base of the drainage system is particularly stable. Thus, the base does not deform even with large quantities of wastewater. This ensures the functionality of the base, in particular the alignment of the base during use relative to the horizontal, even with large quantities of wastewater.

[0019] The longitudinal directions of the reinforcement sections can essentially run in the direction of the drain outlet opening. One advantage of this is that the reinforcement sections direct the wastewater even more precisely toward the drain outlet openings. This further prevents the accumulation of wastewater or wastewater remaining on parts of the drainage system.

[0020] According to the invention, the floor elements of the floor are designed to slope downwards toward the opening of the drain outlet. This ensures that no significant amounts of wastewater can remain on any of the floor elements, thus preventing dirt residues from evaporating wastewater from forming on the floor elements.

[0021] The drainage system can be designed to be mirror-symmetrical with respect to a mirror plane that runs through the center of the drain outlet opening and perpendicular to the connecting walls. This simplifies the technical manufacture of the drainage system. This reduces the manufacturing costs of the drainage system. Furthermore, the installation of the drainage system in the floor is simplified, as the orientation of the drainage system is arbitrary, meaning that the two longitudinal ends of the drainage system can be interchanged as desired.

[0022] In another embodiment, at least some of the corners of the floor are rounded. This allows for even more reliable drainage of wastewater. It also makes cleaning the corners of the floor easier.

[0023] Preferred embodiments are set out in the dependent claims. The invention is explained in more detail below with reference to drawings of exemplary embodiments. Fig. 1 is a perspective X-ray view of a first embodiment of the drainage device according to the invention; Fig. 2 is a detailed view of the area II of Fig. 1 ; Fig. 3 a perspective X-ray view of a further embodiment of the drainage device according to the invention; Fig. 4 an X-ray view of the drainage device from Fig. 3 ; and Fig. 5 a lateral X-ray view of the drainage device from Fig. 3 or Fig. 4 .

[0024] In the following description, the same reference numbers are used for identical and equivalent parts.

[0025] Fig. 1 shows a perspective X-ray view of a first embodiment of the drainage device 5 according to the invention. The drainage device 5 is, for example, a drainage channel that is installed in a floor, such as a tiled floor. However, it is also conceivable that the drainage device 5 is a shower channel. The drainage device 5 can also be a channel element.

[0026] The drainage device 5 comprises a base 10. The base 10 collects the wastewater and directs the wastewater into an opening 82 of a drain nozzle 80. The drain nozzle 80 serves to connect the drainage device 5 to a wastewater pipe or the sewer system.

[0027] Fig. 2 shows a detailed view of area II from Fig. 1 The base 10 is defined by outer edges 14 and corners 12. The outer edges 14 are rounded. The corners 12 are also rounded.

[0028] The drainage device 5 comprises on the two opposite long sides (in Fig. 1 top right and bottom left) each have a support surface 40. On the short and transverse sides (in Fig. 1 There is no support surface 40 on the short sides (top left or bottom right). However, it is also conceivable that a support surface is also provided on the short sides.

[0029] The base 10 (on the two long sides of the drainage device 5) transitions via rounded outer edges 14 into a connecting wall 25 and then, via outer edges 35, which are also rounded, into an end surface 40. The connecting wall 25 is arranged in use such that it runs essentially vertically. The base 10 thus transitions smoothly into the edges 14, then into the connecting wall 25 and, via the outer edges 35, into the support surface 40. The support surface 40 slopes downwards towards the base 10 or the opening 82 of the drain nozzle 80, i.e., the support surface 40 is (slightly) inclined relative to a horizontal line. As a result, the wastewater flows safely and quickly away from the support surface 40. It does not collect on the support surface 40, and essentially no wastewater remains on the support surface 40.

[0030] On the side facing away from the connecting wall 25, the support surface 40 seamlessly transitions into upper outer edges 45 of the support surface 40. The upper outer edge 45 of the support surface 40, in turn, seamlessly transitions into a connecting wall 50 between the support surface 40 and an upper edge surface 65. The connecting wall 50 then seamlessly transitions into the rounded outer edge 60 of the upper edge surface 65. Finally, the rounded outer edge 60 seamlessly transitions into the upper edge surface 65. This means that the outer edges 45 of the support surface 40 and the outer edge 60 of the upper edge surfaces 65 are rounded. The connecting wall 50 between the support surface 40 and the upper edge surface 65 is essentially vertically aligned during use. The upper edge surface 65 forms an outer enclosure of the drainage device 5.

[0031] The support surface 40 serves to support a cover element (not shown). The cover element covers the floor 10 of the drainage device 5. The cover element has a walkable surface that, during use, is substantially flush with the upper edge surface 65. During use, the surface of the cover element runs substantially horizontally. The cover element can, in particular, be a cover grid or a cover grate. The wastewater passes through slots in the cover element into the interior of the drainage device 5 or to the floor 10.

[0032] The upper edge surface 65 serves as a visible surface. This means that after inserting the cover element and installing the drainage device 5 into the floor, normally only the upper edge surface 65 and the surface of the cover element are directly visible. Of course, other parts of the drainage device 5 are visible through the slots in the cover element.

[0033] The corners 12 of the base 10 are also rounded. Thus, there is a smooth transition in the corner areas between the outer edges 14 of the base 10 along the long side of the drainage device 5 and the outer edges 14 of the base along the short or transverse side of the drainage device 5. The edge 45 of the support surface 40 in the corner area is also rounded.

[0034] It is also conceivable that only some of the (outer) edges and / or corners are rounded.

[0035] In Fig. 1 and Fig. 2 the entire support surface 40 on the two opposite long sides of the drainage device 5 is designed to slope down towards the floor 10. The entire upper edge surface 65 (ie on both long sides and on both short or transverse sides of the drainage device 5) is in Fig. 1 and in Fig. 2 designed to slope downwards towards the base 10. It is also conceivable that only a part of the upper edge surface 65 and / or the support surface 40 is designed to slope downwards towards the base 10 or the opening 82 of the outlet nozzle 80; for example, only the upper edge surface 65 on the two long sides or on the two short or transverse sides. In the embodiment shown in Fig. 1 and Fig. 2 the entire upper edge surface 65, the entire support surface 40 as well as all corners 12 of the base 10, all edges 14 of the base 10, all (upper and lower) edges 35, 45 of the support surface 40 and the entire (circumferential) edge 60 of the upper edge surface 65 are rounded or designed to slope downwards towards the base 10 or towards the opening 82 of the drain outlet 80. This applies to the corresponding elements on both long sides of the drainage device 5. It is also conceivable that one or some of the aforementioned elements and / or only parts or regions of the aforementioned elements are rounded or designed to slope downwards towards the base 10.

[0036] The base 10 has a plurality of base elements 16, 16'. The base elements 16, 16' are connected to one another via connecting edges 18. The base elements 16, 16' are inclined at an angle to one another. This means that the base elements 16, 16' form an acute angle to one another and, in use, to the horizontal. The base elements 16, 16' are also designed to slope downwards towards the opening 82 of the drain connection 80. The base 10 comprises, in the Fig. 1 The embodiment shown comprises four substantially rectangular floor elements 16, 16' of equal size. Other shapes of the floor elements, such as triangular, pentagonal, hexagonal, etc., are also conceivable.

[0037] The base 10 may have (in particular linear) reinforcement regions (not shown). In the reinforcement regions, the base has a greater thickness (measured in the vertical direction during use) than the regions of the base 10 outside the reinforcement regions. The longitudinal directions (greatest dimensions) of these (linear) reinforcement regions may extend substantially in the direction of the opening 82 of the drain connection 80.

[0038] Fig. 3 shows a perspective X-ray view of a further embodiment of the drainage device 5 according to the invention. Fig. 3 The embodiment shown differs from the first embodiment of the Fig. 1 and Fig. 2 only in that the drain device 5 additionally has fastening elements 90, height adjustment elements 95 and feet 96 of the height adjustment elements 95. Fig. 4 shows an X-ray view from above (in use) of the drain device from Fig. 3 . Fig. 5 shows a side X-ray view of the discharge device 5 from Fig. 3 or 4.

[0039] The drain device 5 from the Fig. 3 bis 5 has fastening elements 90. These fastening elements 90 extend essentially perpendicular to the connecting walls 25, 50 outwards, ie away from the drain connection 80. The fastening elements 90 serve to fasten the drain device 5 in or on the floor in which the drain device 5 is installed. The fastening can be carried out, for example, by screwing, riveting, gluing or by means of other fastening methods. The drain device 5 has in Fig. 4 six equally spaced fastening elements 90, three on each long side of the drainage device 5. Other arrangements of the fastening elements are conceivable, such as just two, three, four, or five fastening elements. A larger number than six fastening elements, e.g., seven or eight fastening elements, is also conceivable.

[0040] The discharge device 5 has at or near its two opposite longitudinal ends (in Fig. 4 right and left) arranged on the two opposite long sides (in Fig. 4 top and bottom) according to the invention has a total of four height adjustment elements 95. These height adjustment elements 95 can, for example, be screws or threaded bolts with a nut. The height adjustment elements 95 stand on feet 96 or are connected to feet 96. The height adjustment elements 95 serve to adjust the height of the respective area of ​​the drainage device 5. They serve to align the drainage device 5 with respect to the floor or with respect to the horizontal. The height adjustment elements 95 are adjusted such that the opening 82 of the drain nozzle 80 is located at the lowest point of the drainage device 5. In addition, the drainage device 5 is installed or aligned in the floor such that the connecting walls 25, 50 run essentially vertically. Furthermore, during installation, care is taken to ensure that the angle of the support surface 40 to the horizontal on the two opposite long sides (in Fig. 3 left and right or in Fig. 4 top and bottom) and the angle of the upper edge surface 65 to the horizontal are essentially the same on all sides of the drainage device 5.

[0041] The opening 82 of the drain nozzle 80 is round. Other shapes are also conceivable, such as oval, elliptical, triangular, square, pentagonal, hexagonal, etc. It is also conceivable that more than one drain nozzle, e.g., two drain nozzles, with corresponding openings are present. The opening 82 of the drain nozzle 80 is located in the base 10 of the drainage device 5.

[0042] The drainage device 5 can be designed mirror-symmetrically with respect to a mirror plane S1, which runs through the center M of the opening 82 of the drain connection 80 and perpendicular to the connecting walls 25, 50. The Fig. 4 The embodiment shown is designed to be mirror-symmetrical except for the two middle connecting elements 90.

[0043] The upper edge surface 65 serves as the outer enclosure of the drainage device 5. It is located in Fig. 4 thus both left, right, top and bottom. A support surface 40 is located in Fig. 4 only at the top and bottom, while on the right and left side of the drain device in Fig. 4 no support surface 40 is present. However, it is also conceivable that part of the support surface 40 is present in this area (ie on the short transverse sides of the drainage device 5).

[0044] The cover element or the contact surfaces of the cover element can be designed to complement the support surface 40, so that there is extensive contact between the cover element and the support surface 40. Contact or contact between the cover element and the support surface 40 only over a thin linear area is also conceivable. The cover element can be firmly connected to the support surface 40 or formed integrally with the support surface 40. It is also conceivable for the cover element to be a separate element that can be (removably) connected to the support surface 40 or the drainage device 5, e.g., by screwing and / or gluing.

[0045] In Fig. 5 It is particularly clearly visible that all surfaces 10, 40, 65 of the drainage device 5, which are designed to contact the wastewater, are designed to slope downwards toward the base 10 or the opening 82 of the drain connection 80. Sloping means that the respective surfaces have an angle to the horizontal that is in the range from greater than zero to less than 90 degrees.

[0046] The drainage device 5 is also mirror-symmetrical to a further mirror plane S2, which is perpendicular to the mirror plane S1. The mirror plane S1 runs through the center point M of the opening 82 of the drain connection 82 and is perpendicular to the long side of the drainage device 5 (in Fig. 4 left or right).

[0047] The drainage device 5 has a substantially rectangular outer shape. Other (outer) shapes such as round, oval, elliptical, circular, triangular, square (not rectangular), pentagonal, hexagonal, etc. are conceivable.

[0048] The support surface 40 can, in particular, have an angle of approximately 50 degrees to the horizontal. In use, the height difference between the surfaces of different areas of the floor 10 is at least approximately 3 mm. The width of the floor 10 is approximately 163 mm. The total height of the drainage device 5 is approximately 50 mm. The distance between the upper edges of the opposing support surfaces 40 is approximately 200 mm.

[0049] The connecting edges 18 between the floor elements 16, 16' of the floor 10 are in Fig. 4 (ie viewed from above) are aligned perpendicular to each other.

[0050] The radii of the various roundings of the different corners 12 or edges 14, 35, 45, 60 can be the same size. However, it is also conceivable that the radii of different corners 12 and edges 14, 35, 45, 60, or of the corners 12, are different from the edges 14, 35, 45, 60. Bezugszeichenliste:
