Description

[0001] The invention relates to a sanitary floor drainage device according to the preamble of claim 1.

[0002] Floor drains of this type comprise a drain body, an inlet basin within the drain body, and a fluid inlet into the inlet basin. Water entering the inlet basin via the fluid inlet is then drained away. Floor drains of this and similar types are used, for example, for floor drains in shower rooms, bathtubs, sinks, and the like. The inlet basin can be formed by a siphon, which acts as a trap, or be located downstream of one.

[0003] In the patent application WO 2014 / 067616 A1, a generic floor drain device is disclosed, designed for installation below drains, in particular those of walk-in showers, and comprising a horizontally arranged pump with which water located in a collection chamber serving as an inlet basin can be pumped out. The pump's suction area is located in the inlet basin, and the pump section, containing the pump's electrical components, is located in a pump chamber that is watertight from the inlet basin. This allows the water collected in the collection chamber to be pumped out of the floor drain device even overcoming a difference in height.

[0004] The invention is based on the technical problem of providing a sanitary floor drain device of the type mentioned above, which offers further advantages over the prior art mentioned above, in particular with regard to an extended functionality of the floor drain device.

[0005] The invention solves this problem by providing a sanitary floor drainage device with the features of claim 1. Advantageous embodiments of the invention are specified in the dependent claims, the wording of which is hereby incorporated by reference into the description. This includes, in particular, all embodiments of the invention resulting from the combinations of features defined by the cross-references in the dependent claims.

[0006] According to the invention, the sanitary floor drain device thus includes, in addition to its generic components mentioned above, an outlet basin in the drain housing body, a dirt filter arrangement via which the outlet basin is in fluid communication with the inlet basin, a fluid outlet from the outlet basin and an overflow outlet from the inlet basin.

[0007] This inventive design of the floor drain device enables the fluid entering the floor drain device, in particular water from a shower, bathtub, or sink, to be freed from dirt, especially coarse dirt, by the dirt filter arrangement, which separates this dirt on the dirt filter arrangement. The fluid filtered in this way enters the outlet basin and can be drawn off from it via the fluid outlet. The fluid drawn from the outlet basin, freed from dirt or coarse dirt, can be used for a suitable purpose, for example, in the case of water, as so-called greywater for toilet flushing and washing machines, and for garden irrigation. The overflow outlet can function as an emergency or backup outlet if, or to the extent that, the fluid cannot pass from the inlet basin into the outlet basin via the dirt filter arrangement, e.g.,because the fluid is too contaminated or the dirt filter assembly is clogged.

[0008] Dirt filtration directly through the floor drain eliminates the need for dirt filtration in a downstream device, such as a greywater treatment plant. Furthermore, dirt separation within the floor drain facilitates the conveyance of the now dirt-free fluid to a downstream fluid utilization device. Moreover, the floor drain according to the invention, due to its generic features, possesses the associated functions and properties known to those skilled in the art.

[0009] In a further development of the invention, the floor drain device has a collection basin that is divided into an inlet basin and an outlet basin by a filter partition unit of the dirt filter assembly. The inlet basin and the outlet basin are thus jointly formed by the collection basin, with the filter partition unit serving to divide the collection basin into the inlet basin and the outlet basin. Alternatively, the outlet basin can be spaced apart from the inlet basin and connected to it, for example, via a fluid-conveying channel.

[0010] In one embodiment of the invention, the inlet basin and the outlet basin are arranged at least partially one behind the other, side by side, and / or one above the other in the drain body, and the filter partition unit comprises at least one horizontally extending filter wall and / or one vertically extending filter wall and / or one inclined filter wall between the inlet basin and the outlet basin. This represents an advantageous spatial arrangement of the inlet basin and outlet basin in the drain body. Depending on the geometric design of the inlet basin and the outlet basin and depending on the application, the filter partition unit has one or more filter walls, at least one of which extends horizontally, vertically, or inclinedly and functions as a partition between the inlet basin and the outlet basin. Horizontal or inclined filter walls are defined as...Vertical here refers to the spatial orientation of the respective filter wall in the installed and operating position of the floor drain device and, in particular, the drain body. In the case of an inclined design, the filter wall has an extension component in both the horizontal and vertical directions; that is, the filter wall runs at an angle to the vertical and horizontal, respectively. The filter wall can be designed as a removable component, thus enabling advantageously simple cleaning of the filter partition unit.

[0011] In a further embodiment of the invention, the filter partition unit comprises at least two filter walls spaced apart one behind the other in the direction of fluid flow. This measure enables a staged filtration effect of the dirt filter arrangement through the two or more filter walls, which are sequentially flowed through by the fluid. Depending on requirements and application, the two filter walls arranged in series can be implemented with the same or different filtration effects, for example, a finer filtering filter wall behind a coarser filter wall. In alternative embodiments, the filter partition unit comprises only a single filter wall in the direction of fluid flow if this is sufficient for the respective applications.

[0012] In another embodiment of the invention, the filter partition unit comprises a filter basket, the interior of which forms the inlet basin. This represents a technically simple and advantageous implementation of the filter partition unit for filtration. The filter basket can preferably contribute to the filtration effect with both its base and its side walls, as these areas are designed as filter walls or filter surfaces. In this case, the outlet basin can surround the inlet basin from below and / or on one, several, or all sides. In alternative embodiments, the filter partition unit can, for example, be implemented by a single filter plate or filter surface. The filter basket can be designed as a removable component, thus enabling advantageously simple cleaning of the filter partition unit.

[0013] In another embodiment of the invention, the inlet basin comprises an inlet basin section arranged next to the outlet basin and a further inlet basin section arranged above the outlet basin, with the horizontally extending filter wall separating the outlet basin from the further inlet basin section arranged above it. This allows the fluid, for example, to flow into the inlet basin section next to the outlet basin and from there into the further inlet basin section above the outlet basin, thereby flooding the horizontal filter wall and passing through it into the outlet basin. Excess or heavily contaminated fluid can be discharged via the overflow outlet, which for this purpose leads, for example, from the further inlet basin section located above the outlet basin to the bottom drain device.

[0014] In yet another embodiment of the invention, the overflow outlet comprises an overflow outlet opening spaced laterally and / or vertically from the discharge basin and / or an overflow wall, downstream of which, in the direction of fluid flow, an overflow chamber is arranged, from which an overflow outlet opening leads. The overflow wall can optionally form a side wall of the discharge basin. This represents a functionally advantageous design for the overflow outlet, through which the fluid can be drained from the inlet basin if the fluid flow from the inlet basin to the discharge basin is obstructed or blocked. Preferably, the overflow outlet opening is located at a suitable overflow height of the inlet basin, which is above a maximum desired fill level of the inlet basin. In the case of the overflow wall, it similarly has a wall height with which a desired maximum fluid level in the inlet basin can be set.Advantageously, the overflow wall can also function as a tight side wall of the outlet basin if required.

[0015] In a further development of the invention, the floor drain device includes a pump that is arranged with a fluid inlet in the discharge basin or coupled to the fluid outlet. In this embodiment, the floor drain device enables the filtered fluid to be pumped out of the discharge basin. Depending on requirements and application, the pump is designed as a pressure pump or a suction pump. In the case of a pressure pump, its fluid inlet is preferably arranged in the discharge basin. In the case of a suction pump, its fluid inlet is preferably coupled to the fluid outlet of the discharge basin. In alternative embodiments, the floor drain device is designed without a pump if this is not required for the respective applications or if a pump, in particular a suction pump, is located in a device downstream of the floor drain device.

[0016] In one embodiment of the invention, the pump is arranged within the drain body. This represents an advantageous integration of the pump into the floor drain. Housing the pump within the drain body minimizes the space required for the floor drain, including the pump. In alternative embodiments, the pump can, for example, be arranged externally on the drain body.

[0017] In a further development of the invention, a trap unit is positioned upstream of the inlet basin in the direction of fluid flow within the drain body. This advantageously provides the floor drain with an additional odor trap function. The trap unit can, for example, comprise a conventional siphon unit or a standard mechanical odor trap, such as a flap. The trap unit can be integrated into the drain body, which is advantageous for achieving a compact floor drain. In alternative embodiments, the floor drain does not have such a siphon unit, or a siphon unit is arranged outside the drain body, particularly upstream of the inlet basin in the direction of fluid flow.

[0018] In one embodiment of the invention, the odor trap unit is inserted into the inlet basin or connected to the inlet basin via a fluid channel. The embodiment with the odor trap unit inserted into the inlet basin further contributes to achieving a smaller footprint for the floor drain. The embodiment in which the odor trap unit is connected to the inlet basin via the fluid channel is particularly suitable for applications where the inlet basin does not offer sufficient space for inserting the odor trap unit. In the latter case, the odor trap unit does not need to be considered when dimensioning the inlet basin.

[0019] In a further development of the invention, the floor drain device includes a removable cover that covers at least the inlet basin. This allows the inlet basin to be concealed from view. The cover can also prevent dirt and the like from entering the inlet basin from above. The cover can be, in particular, removable from the drain body. Since the cover is removable, it does not obstruct access to the inlet basin. For example, the cover can be removed for cleaning and maintenance. Depending on requirements and application, the outlet basin can also be covered by the same or another, preferably removable, cover. In alternative embodiments, the cover can be omitted if it is not problematic for the respective application that the inlet basin remains open at the top.In other alternative designs, the inlet basin can also be covered with a fixed, i.e. non-removable, cover, especially if there is no need for the inlet basin to remain accessible from above.

[0020] In one embodiment of the invention, the cover has a recess for inserting the odor trap unit. Advantageously, in this case, the cover also serves as a receptacle for inserting the odor trap unit. Alternatively, the odor trap unit can be arranged elsewhere or inserted into the inlet basin. The cover can have at least one further recess, which can be closed, particularly watertight, by means of a cover element, especially a pivotable one. The at least one further recess can, for example, serve as a maintenance opening for the filter partition unit and / or the pump.

[0021] In a further development of the invention, the drain body is designed as a channel-shaped housing. This represents a design advantageous for many applications. In particular, this design is suitable for channel-shaped floor drains, especially for so-called shower channels, as commonly used in shower rooms. In alternative embodiments, the drain body is of a different shape, e.g., a cuboid or cylindrical drain body.

[0022] In one embodiment of the invention, the inlet basin and the outlet basin are arranged one behind the other in a longitudinal direction of the drain body. This represents an optimal arrangement of the inlet basin and outlet basin in the channel-shaped drain body for many applications, which facilitates achieving a small footprint. In alternative embodiments, the inlet basin and the outlet basin can be arranged side by side transversely to the longitudinal direction of the channel.

[0023] In corresponding designs, the pump and the outlet basin are arranged one behind the other in a longitudinal channel direction of the outlet housing body.

[0024] This measure facilitates the achievement of a small footprint for floor drain devices with a pump, while simultaneously ensuring the optimal functional position of the pump relative to the outlet basin. In alternative designs, the pump and outlet basin can also be arranged side-by-side, perpendicular to the longitudinal direction of the drain body, if this offers advantages for specific applications.

[0025] Advantageous embodiments of the invention are illustrated in the drawings. These and further embodiments of the invention are explained in more detail below. The drawings show: Fig. 1 is an exploded view of a first embodiment of the floor drain device according to the invention with two inclined filter plates and integrated siphon; Fig. 2 is a perspective view of the floor drain device. Fig. 1 , Fig. 3 a cutaway side view of the floor drainage device of Fig. 1 Fig. 4 a schematic side view of a second embodiment of the floor drain device according to the invention with a filter basket, Fig. 5 a schematic perspective view of a third embodiment of the floor drain device according to the invention with a more complex filter geometry, an overflow wall and separate siphon, Fig. 6 an exploded view of a fourth embodiment of the floor drain device according to the invention with a substantially horizontal filter plate and integrated siphon, Fig. 7 a cutaway side view of the floor drain device of Fig. 5 and Fig. 8 a top view of the floor drainage device of Fig. 5 , where a cover and a cover plate of the floor drain device are hidden.

[0026] As can be seen from the figures, which illustrate advantageous exemplary embodiments, the sanitary floor drain device according to the invention comprises a drain body 1, an inlet basin 2 arranged in the drain body 1, a fluid inlet 3 opening into the inlet basin 2, and an overflow outlet 4 opening from the inlet basin 2. Furthermore, the sanitary floor drain device according to the invention comprises an outlet basin 5 arranged in the drain body 1, a dirt filter arrangement 6 through which the outlet basin 5 is in fluid communication with the inlet basin 2, and a fluid outlet 7 from the outlet basin 5.

[0027] The overflow outlet 4 acts as an emergency or backup outlet, meaning that the fluid can flow out of the inlet basin 2 via the overflow outlet 4 if the fluid outlet 7 from the inlet basin 5 or a downstream component of the bottom drain device is blocked, so that the inlet basin 2 does not overflow.

[0028] In corresponding embodiments, as in the examples shown, the sanitary floor drain device comprises a collection basin 8, which is divided into the inlet basin 2 and the outlet basin 5 by a filter partition unit 9 of the dirt filter arrangement 6. The inlet basin 2 and the outlet basin 5 are thus jointly formed by the collection basin 8, as for example in the Fig. 3 The collection basin 8 typically comprises a bottom and side walls, the bottom preferably having a slope towards the fluid outlet 7, as shown in Fig. 3evident, and the side walls rise essentially vertically from the ground.

[0029] In corresponding implementations, the inlet basin 2 and the outlet basin 5 are arranged at least partially side by side in the drain body 1. In the embodiments according to the Figs. 4 to 8 The inlet basin 2 and the outlet basin 5 are arranged at least partially one above the other in the drain body 1.

[0030] In corresponding implementations, the filter partition unit 9 includes at least one substantially horizontal filter wall 9 1 between the inlet basin 2 and the outlet basin 5, as shown in the Figs. 4 to 8The examples shown illustrate this. In these examples, the filter partition unit 9 includes a substantially horizontal filter wall 9 1. A slight inclination to the horizontal can, if necessary, facilitate the flow of the fluid. The filter partition unit 9 according to the sanitary floor drain device of Fig. 4 It also includes at least one vertically extending filter wall 9 2 between the inlet basin 2 and the outlet basin 5. In this embodiment, the filter partition unit 9 includes four vertically extending filter walls 9 2. The embodiments of the Figs. 1 to 3 and 5 Each figure shows a filter partition unit 9, which includes at least one inclined filter wall 9s between the inlet basin 2 and the outlet basin 5. The example of Fig. 5 The curved shape of the inclined filter wall 9 3 can advantageously function as an overflow ramp for the fluid.

[0031] In advantageous embodiments, the filter partition unit 9 comprises at least two filter walls 9 3 , 9 4 spaced apart one behind the other in the fluid flow direction, as in particular in the Fig. 3 The filter walls 9 3 , 9 4, which are arranged one behind the other, are flowed through serially by the fluid as the fluid flows from the inlet basin 2 into the outlet basin 5.

[0032] In an embodiment not shown, the sanitary floor drain device according to Fig. 3 only a single filter wall for 9 seconds.

[0033] In corresponding implementations, the filter partition unit 9 includes a filter basket 9s, the interior of which forms the inlet basin 2, see Fig. 4In this example, the filter basket 9s has four substantially vertical filter walls 9 2, which form the basket side walls, and one substantially horizontal filter wall 9 1, which forms the basket bottom, between the inlet basin 2 and the outlet basin 5. The outlet basin 5 surrounds the inlet basin 2 on its underside and on all sides, in particular by at least one narrow channel belonging to the outlet basin, adjacent to the inlet basin. In alternative embodiments not shown, the outlet basin 5 is not surrounded by the inlet basin 2 on all sides, but, for example, only on one side, or the outlet basin includes a pipe or the like that extends through the inlet basin 2.

[0034] In corresponding embodiments, the inlet basin 2 comprises an inlet basin part 2a arranged next to the outlet basin 5 and a further inlet basin part 2b arranged above the outlet basin 5 and in fluid communication with it, as in the exemplary embodiment of the Figs. 6 to 8 The inlet basin section 2a is surrounded on all sides, i.e., all longitudinal and transverse sides, by the outlet basin 5, as shown in particular in Fig. 8As shown, alternatively, the outlet basin 5 can, for example, only pass by the inlet basin section 2a on one side. The horizontally extending filter wall 9 1 separates the outlet basin 5 from the inlet basin section 2b located above it. In this embodiment, the fluid initially flows into the inlet basin section 2a, which can, for example, also be formed as a water barrier of a siphon, next to the outlet basin 5. When the fluid in the inlet basin section 2a reaches a certain fill level, the fluid flows from this inlet basin section 2a into the inlet basin section 2b above the outlet basin 5, thereby flooding the horizontally extending filter wall 9 1 and the fluid enters the outlet basin 5 completely or partially. The inlet basin section 2b, located above the outlet basin 5, also includes the overflow outlet 4, through which excess or more heavily contaminated fluid can flow out of the bottom drain device, as is particularly evident in the Fig. 7shown.

[0035] In corresponding implementations, the overflow outlet 4 comprises an overflow outlet opening 4 1 spaced laterally from the discharge basin 5, as in the design according to the Figs. 6 to 8 is shown. Alternatively, the overflow outlet 4 includes an overflow wall 4 2, downstream of which, in the fluid flow direction, an overflow chamber 4s is connected, see Fig. 2 An overflow outlet opening 44 leads from the overflow chamber 43. The overflow outlet 4 allows fluid to be automatically drained from the inlet basin 2 if the fluid flow from the inlet basin 2 to the outlet basin 5 is obstructed or blocked, or if no pumping from the outlet basin 5 takes place. In the design according to the Fig. 5The overflow wall 4 2 functions as a sealed side wall of the outlet basin 5. In the examples shown, the overflow outlet 4 is located at a suitable overflow height of the inlet basin 2, which is above a maximum desired fill level of the inlet basin 2, as for example in Fig. 4 is shown.

[0036] In corresponding embodiments, the sanitary floor drain device further comprises a delivery pump 10 in the form of a pressure pump, which is arranged with a fluid inlet part 10a in the outlet basin 5, as shown in the Fig. 3 and 8 as shown. Alternatively, a feed pump 10 in the form of a suction pump with a fluid inlet part 10a is coupled to the fluid outlet 7 of the discharge basin 5, as shown in the Fig. 4The pumps 10 enable the filtered fluid to be pumped out of the outlet basin 5. In the illustrated embodiments, the pumps 10 are arranged within the outlet housing 1. If the pump 10 is deactivated, the fluid can, if necessary, flow out of the inlet basin 2 via the overflow outlet 4 as an emergency or backup outlet.

[0037] In one embodiment (not shown), the pump 10 is arranged externally on the drain body 1. In another embodiment (not shown), the pump 10 is arranged spatially separate from the drain body and is connected to the fluid outlet 7 by means of a fluid line.

[0038] The sanitary floor drain device according to Fig. 5 is designed without such a pump 10.

[0039] In advantageous embodiments, an odor trap unit 11 is positioned upstream of the inlet basin 2 in the direction of fluid flow. In the embodiments according to the Figs. 1 to 3 and 6 to 8 The odor trap unit 11 is inserted into the inlet basin 2 in the form of a siphon unit. Alternatively, in the design according to Fig. 5 The odor trap unit 11 is connected separately in the form of a siphon unit to the inlet basin 2 via a fluid channel 12.

[0040] The floor drain device according to Fig. 4 does not have such an odor trap unit 11, however, such an odor trap unit 11 can be installed upstream of the floor drain device outside the drain housing body 1, preferably in the direction of fluid flow, in front of the inlet basin 2.

[0041] In corresponding implementations, as in the examples shown, the sanitary floor drain further comprises a removable cover 13, which covers at least the inlet basin 2 in a fluid-tight and concealed manner. The removable cover 13 of the inlet basin 2 prevents dirt from entering the inlet basin 2 while simultaneously allowing access to it. Furthermore, the cover 13, in conjunction with the odor trap provided by the odor seal unit 11, can also serve as an odor-tight cover for the floor drain.

[0042] In an embodiment not shown, the sanitary floor drain device does not have such a removable cover 13, so that the inlet basin 2 is open at the top.

[0043] In advantageous embodiments, the cover 13 has a recess 14 for inserting the odor trap unit 11, as shown in the examples according to the Figs. 1 to 3and 6 to 8 is shown.

[0044] In advantageous embodiments, as in the examples shown, the drain body 1 is designed as a trough-shaped housing body.

[0045] In corresponding embodiments, the inlet basin 2 and the outlet basin 5 are arranged one behind the other in a longitudinal channel direction RL of the drain body 1, as is particularly evident in the Fig. 2 , 4 and 6 The pump 10 and the outlet basin 5 are preferably arranged one behind the other in the longitudinal direction RL of the outlet body 1.

[0046] In advantageous embodiments, the feed pump 10 and the discharge basin 5 are arranged one behind the other in the longitudinal direction RL of the drain body 1, as in the embodiments according to the Fig. 3 and 7 shown.

[0047] In embodiments not shown, the feed pump 10 and the outlet basin 5 are arranged side by side transversely to the longitudinal direction RL of the drain body 1.

[0048] In corresponding implementations, the sanitary floor drain device includes a fill level sensor 19, as in the Fig. 1 , 4 and 8 The level sensor 19 can, for example, be a float switch. The level sensor 19 activates the pump 10 when a defined level is reached in the inlet basin 2. Additionally, it is also conceivable that the pump 10 is activated or deactivated depending on the level in the outlet basin 5 or by predefined switching programs, for example, to run a regular cleaning program.

[0049] In advantageous embodiments, as described in the Fig. 1, 3 , 6 and 7The sanitary floor drain device includes a cover plate 15, which is located in the user's field of vision, e.g., in a shower room. The cover plate 15 is removable from above the cover 13 and can be removed, for example, to clean the odor trap unit 11. The cover plate 15 thus conceals the recess 14 and the odor trap unit 11 inserted therein. In the illustrated embodiments, the cover plate 15 is designed such that fluid can flow laterally along the edge into a cavity between the cover plate 15 and the cover 13 and from there towards the fluid inlet 3. Alternatively, the cover plate 15 could also be designed as a grate with a plurality of openings, whereby the fluid can flow through the openings into the cavity between the cover plate 15 and the cover 13 and from there towards the fluid inlet 3.

[0050] In the versions shown, the floor drain device has an inlet frame at the top into which the cover plate 15 is inserted, as shown in the Fig. 1, 2 , 8 and 9. The inlet frame preferably serves as a boundary for a surrounding floor covering. In the upper area of ​​the drain body 1, particularly adjacent to the inlet frame, a flange preferably projects horizontally from the drain body 1, as can also be seen from the Fig. 1, 2 , 8 and 9. The flange can be advantageous for simple and precise installation of the floor drain. A moisture-resistant sealing element can be attached to the flange in a manner known per se.

[0051] In the embodiment according to the Fig. 6A flap cover 17 is also provided. For this purpose, the cover 13 has a further recess 18 for the fluid-tight insertion of this flap cover 17. The flap cover 17 allows access to the filter partition unit 9.

[0052] In appropriate versions, the sanitary floor drain device includes 1 height-adjustable feet 16 on the outside of the drain body, as in particular in the Fig. 3 and 6 The height-adjustable feet 16 enable height adjustment and alignment of the floor drain device, in particular the fluid inlet 3, within the available installation space.

[0053] As the illustrated and further embodiments described above clearly demonstrate, the invention provides a floor drain device with extended functionality. The floor drain device according to the invention enables the fluid entering the floor drain device, in particular water from a shower, bathtub, or sink, to be freed from dirt, especially coarse dirt, by the dirt filter assembly 6, which separates this dirt on the dirt filter assembly 6. The fluid filtered in this way enters the outlet basin 5 and can be drawn off from it via the fluid outlet 7. The fluid drawn from the outlet basin 5, freed from dirt or coarse dirt, can be used for a suitable purpose, for example, in the case of water, as so-called greywater for toilet flushing and washing machines, and for garden irrigation.
