Description

The present invention relates to a cistern arrangement for flushing a sanitary ceramic according to the preamble of claim 1.

In principle, when flushing a sanitary ware, for example a toilet bowl or a urinal sink, water splashes can escape through the sanitary ware. Taking the toilet bowl as an example, according to the European standard EN 997, flushing of the toilet bowl must be ensured and spills, in short overspraying, must be avoided. Especially in so-called rimless toilet bowls, in which no peripheral rim is provided, this leads to increased demands on the precision in the manufacture of the sanitary ware.

In addition, there are different cisterns available on the market, which in turn have different rinsing flows. Older cisterns in particular regularly have rinsing flows in the range of 3 liters per second and newer cisterns have rinsing flows of 2 to 2.4 liters per second. The maximum flushing current is reached shortly after the start of the flushing process, approximately after 0.2 seconds. The flushing flow then decreases continuously due to the falling water level in the cistern via the flushing process. Thus, especially when the rimless toilet bowl is in operation, the maximum flushing current that is quickly present at the start of the flushing process can lead to over-splashing. However, it is problematic to adapt the flushing flow of the different cisterns to the toilet bowl, urinal bowl or the like to be connected when installing the sanitary ceramic, to avoid over-splashing. In this respect, a large number of different cisterns are available on the market, especially for the rimless toilet bowls from the various manufacturers, which do not exceed the maximum flushing current recommended for the respective toilet bowl. The sanitary ware must not have a too low flushing flow to ensure that the sanitary ware as well as the subsequent sewage pipes are sufficiently flushed.

The DE 80 06 070 U1 discloses a waste set for cisterns, by means of which the amount of water flowing into the toilet bowl or the like per unit time can be regulated. A height-adjustable ring is arranged on an outside of a housing of the drain fitting and, depending on its position, changes the free height of windows which are formed on the housing.

From the US 4,388,737 B. a cistern is known which has a plurality of partitions, so that a plurality of chambers are formed. According to one embodiment, a through opening is provided in a partition, which can be closed or opened by a pivotable slide. According to a further embodiment, a plurality of openings are provided in a partition, which can be closed by plugs.

From the US 2013/0180039 A1 a cistern with a drain valve is known. A flow adjustment body is arranged around the drain valve. The adjustment body is rectangular and open at the top. The adjustment body has flow openings in its side walls, through which water can get from the water box into the interior of the adjustment body. The flow openings can be covered with adjustment lids, which can be connected to the adjustment body in different positions.

From the EP 2 602 391 B1 a flushing water distributor for reducing the flushing flow is known, which is used in a rimless toilet bowl. The rinse water distributor has an elongated, half-shell-like base body in which two parallel inner walls are formed. Due to the inner walls, the rinse water distributor is divided into three flow channels, each of which has an area bent at the end with a lateral outlet opening for deflecting the rinse water. On the input side, the flushing water distributor has a flushing flow restrictor which is detachably fastened to the base body and by means of which the flushing water flowing into the flushing water distributor is to be disentangled or calmed down. In order to prevent the flushing water distributor made of plastic from being visible to a user of the toilet bowl for optical reasons, the flushing rimless toilet bowl has a cover which is fastened in front of it after the flushing water distributor has been inserted.

However, several of the known flushing flow restrictors, each with a differently strong flushing flow restrictor effect, must be provided in order to be able to adapt the flushing flow of a connected cistern to the toilet bowl. In addition, the entire rinsing water distributor must always be removed in order to adjust the rinsing flow in order to replace the rinsing throttle held on the back of the rinsing water distributor or in the direction of flow on the main body of the rinsing water distributor. This makes the setting of the flushing flow to the toilet bowl complex. Furthermore, it is only possible to equip the toilet bowl with the known flushing flow distributor if a corresponding installation space has been provided in the toilet bowl at the factory.

From the brochure "TECE flushing technology, technical information", 1-2015 from TECE GmbH it is known that the flushing flow can be changed by inserting a flushing flow restrictor in a valve seat of a drain cage used in a concealed cistern. For this purpose, a throttle set is provided with four different throttles, each of which has a different inner diameter. If the flushing flow of the concealed cistern is too high for the connected sanitary ware and the flushing water is splashing over, the flushing current can be reduced by inserting one of the throttles in the valve seat. The flushing flow is highest without a throttle and correspondingly lowest when the throttle with the smallest inside diameter is inserted in the valve seat.

In order to be able to use one of the throttles in the valve seat or to exchange them for another throttle with a different throttling effect, the drain valve interacting with the valve seat must be removed or subsequently reassembled due to the narrow interior of the concealed cistern. In addition, a throttle set with several throttles with different throttling effects must be provided in order to be able to set the flushing current suitable for the connected sanitary ware.

The object of the present invention is to provide a cistern arrangement which can be adapted to a sanitary ware in a simple and inexpensive manner in order to avoid over-splashing.

The object is achieved according to the invention in a cistern arrangement for flushing a sanitary ceramic according to the type mentioned at the outset in that the adjusting device is arranged on the drain valve, the actuating body being moved up together with the drain valve when the flush is actuated and then lowered again together with the drain valve. The adjustment body is arranged to be movable relative to the water tank and adjustable in several drain positions, the flushing flow of the defined amount of flushing water flowing out of the water tank being dependent on or influenced by the drain position of the adjustment body. The height of the adjustment body is kept adjustable on the drain valve, the flushing flow being changeable or adjustable accordingly.

The term “flushing flow” is understood to mean a volume flow, specifically the volume of the flushing water per unit of time through an outlet of the cistern arrangement, in particular the outlet of a drain connector of a cistern.

According to the invention, provision is thus made to set the flushing flow by means of a movable adjusting body, the adjusting body being able to be moved into at least two different drain positions. In the individual drain positions, the adjustment body changes a passage geometry of a passage through which the flushing water flows. As a rule, the smaller the passage geometry, that is, the more the adjustment body narrows the passage, the lower the resulting purge flow. Conversely, the flushing flow is usually maximal when the influence of the adjustment body on the passage is marginal. A first rinsing flow is thus established in the one outflow position on the basis of a first passage geometry influenced by the adjusting body and in the second outflow position on account of a changed second passage geometry a second rinsing flow. For example, the first flushing stream can be a high flushing stream, for example 2.4 liters per second, and the second flushing stream can be a lower flushing stream, for example 2.0 liters per second. In addition to the two aforementioned drain positions, the adjustment body can also be moved into additional drain positions.

Due to the variable adjustability of the adjustment body in the different drain positions, the flushing flow can be changed or adjusted. The adjusting body can be moved into one of the drain positions between individual rinsing processes, in particular between the test rinsing processes carried out by an installer. During the flushing processes, the movable or adjustable adjusting body can be held stationary relative to the water tank or a component of a conventional cistern arrangement, for example the drain valve or a filling valve, arranged in the water tank. The adjusting body can thus also be referred to as an obstacle body or resistance body, which changes or influences the flow in the cistern arrangement. The flowing rinsing water is disturbed in its undisturbed flow, which would occur without the adjusting body, since the adjusting body changes the passage geometry through which the rinsing water flows. In this way, the adjusting body engages in the flushing flow to change the flushing flow.

For example, the position and / or orientation of the adjustment body in relation to the flushing flow can be changed. The movement of the adjustment body can be graded or infinitely variable. As a result, the installer can easily adjust the flushing flow to the individual drain positions by means of the adjustment body inserted or installed in the cistern arrangement, without having to remove it or replace it with another adjustment body. Thus, once the adjustment body has been arranged in the flushing flow, it no longer has to be removed during operation of the sanitary arrangement and especially for setting the flushing flow.

It goes without saying that the reference to the rinsing water and the rinsing flow only serves for a better understanding of the spatial arrangement of the adjusting device in the cistern arrangement, since the water tank is only filled with rinsing water during operation and the rinsing water accordingly only in operation when the drain valve is open the floor opening can drain off.

The flushing flow is changed by moving the adjustment body into one of the drain positions. However, it is not provided that the adjusting body is designed and positioned in such a way that rinsing water is retained in the water tank by the adjusting body or the adjusting device. The total volume of rinsing water available for the rinsing process, that is to say the defined amount of rinsing water, thus remains unchanged. The defined amount of rinsing water can be, for example, a small amount of rinsing water of approximately 3 liters in a cistern with a known dual-flush technique, or a large amount of rinsing water of approximately 4 to 9 liters when selecting full rinsing. The flushing process can be interrupted in a cistern with a known start-stop function, whereby the defined amount of flushing water can be changed manually by pressing the stop button. However, the dual-flush technology or the start-stop function only changes the flush water quantity, the flush flow remaining unchanged.

The flushing flow can be reduced by the adjustment body partially covering or narrowing the area of the passage through which there is no flow, without narrowing it completely. Conversely, the flushing flow can be increased if the adjustment body is adjusted in such a way that the original passage geometry of the passage, which would result without the adjustment body, is reached again. For example, in one of the drain positions, the adjustment body can be arranged such that it is so distant from the passage, or its extension can be reduced in such a way, or it can be aligned parallel to the flow direction of the outflowing rinsing water with such low friction that the influence of the adjustment body on the rinsing water flowing out through the passage is marginal. A change in the flushing flow due to the influence of the adjusting body of a maximum of 5% compared to a flushing current which results without the adjusting body is still considered to be marginal considered.

Furthermore, the setting device can represent an independent structural unit. In particular, the adjusting device is a functionally and structurally separate unit from the drain valve. The setting device can be detachably attached to the drain valve, for example. The setting device is usually adjusted by the installer between two test rinsing processes in order to reduce or increase the rinsing flow. In contrast, the drain valve usually only moves during the rinsing process. The adjusting device thus functions independently of moving components of the drain valve, for example the valve closure part of the drain valve moving between the open position and the closed position. Likewise, the setting device can be moved up and down together with the valve closure part. In particular, the adjustment body is held stationary relative to the valve closure part.

Furthermore, the cistern arrangement can comprise exactly one adjustment body. The adjustment body can be made in one piece or in several parts. In principle, it is also conceivable and possible for the cistern arrangement to have several of the adjusting bodies which are formed in one or more parts. For example, at least one of the adjustment bodies can be arranged in the water tank and / or at least one of the adjustment bodies can be arranged in the outlet connection of the water tank and / or two adjustment bodies can be rotated relative to one another. For the sake of better readability, the at least one adjustment body is briefly referred to as the adjustment body. If exactly one adjustment body is important, it will be pointed out accordingly.

According to one embodiment of the present invention, the adjustment body can be arranged to be movable within the water box. Thus, the adjustment body can be reached by the installer via an inspection opening of the water box and moved into the individual drain positions.

Advantageously, the height of the adjustment body is held within the water box. The influence of the adjustment body on the flushing flow increases, the closer the adjustment body is to the bottom opening of the water tank or the valve seat is arranged, and vice versa. The drain valve usually lifts the valve closure part linearly upward from the valve seat along a travel path between the closed position and the open position. In a conventional cistern without an adjusting body, the flushing water would then flow through the bottom opening between the drain valve and the valve seat. Due to the height adjustment, the adjustment body can be moved up and down, for example, radially spaced from the valve closure part. If the adjustment body is moved upwards to such an extent that the adjustment body does not axially overlap with the travel path of the valve closure part, the adjustment body has no or at most a marginal effect on the flushing flow that arises. If, on the other hand, the adjustment body is adjusted further downwards, the passage between the drain valve and the valve seat is partially covered. This results in a changed passage geometry of the passage, in particular the passage is reduced in size, as a result of which the flow rate, that is to say the flushing flow, is reduced. Furthermore, in the open position of the valve closure part, the adjustment body can also be arranged at least partially in the bottom opening in order to change the passage of the bottom opening, or to narrow it selectively compared to the original passage of the bottom opening.

In particular, guide and / or holding means are provided which hold the adjustment body in the water tank. In this way, the flushing flow can be set simply and reproducibly by the installer when the cistern arrangement is installed. The adjusting body can, for example, be held in a height-adjustable manner in the water tank by being fastened to a guide and / or holding means in the form of an elongated rod which is held on a stationary component of the cistern arrangement, for example a wall of the water tank or a housing of the drain valve , The rod can, for example, be clipped, releasably locked, or fastened to a stationary component within the water box or to the water box itself with a manually operated plastic screw. As a result, the adjustment body in the water tank can be moved up and down in a simple manner, in particular linearly. Likewise, the height of the adjustment body can also be adjusted by a rotary movement. For example, the adjustment body on one be attached to the lower end of a rotating spindle, which in turn can be held on the water tank, drain valve or on a stationary component. Furthermore, the adjustment body can be displaceably guided in the water tank. For example, a guide rail can be attached to the water box, on which the adjustment body can be moved in a guided manner. In particular, the adjustment body is held stationary by the guide and / or holding means, at least during a flushing process, relative to the flushing flow.

In order not to retain any flushing water in the water tank by the adjustment body in the open position, the adjustment body should always be spaced from a bottom of the water tank. For example, an axial longitudinal extent of the adjustment body can be smaller than an axial distance between the valve closure part located in the open position and the valve seat. This ensures that the adjustment body does not completely cover the original passage in any position and that flushing water can always flow out through the passage.

Furthermore, the adjustment body can be dimensionally stable and can only be adjusted in the position and / or orientation to the flushing flow. The adjustment body can be closed in the circumferential direction. The adjustment body can be of hollow cylindrical or frustoconical or frustoconical design. The adjustment body can have a closed outer surface. Alternatively, the adjustment body can have a perforated and / or slotted jacket surface, so that at least a portion of the outflowing rinsing water can flow through the adjustment body before it flows through the passage. This can also slow down the rinsing water and thus reduce the rinsing flow. In particular, an inner radius of the adjusting body can be larger, equal to or smaller than an outer radius of the valve closure part. Furthermore, the adjustment body can be arranged concentrically with the valve seat. If the inner diameter of the adjusting body is larger than that of the drain valve, then the adjusting body can grip around the drain valve and be moved axially up and down to the drain valve. The adjustment body is expediently held adjustable on the drain valve. Furthermore, the adjustment body can be designed interrupted in the circumferential direction. For example, the adjustment body can have a plurality of elements distributed in the circumferential direction. The Elements can, for example, be held relative to one another via guide and / or holding means.

Furthermore, the adjustment body can be held on one of the components usually provided in a water tank of a conventional cistern. Conventional cisterns can thus be easily retrofitted with the setting device.

In particular, the adjustment body can be arranged at least partially within the bottom opening of the water tank, at least in the open position of the valve closure part. In this way, the adjustment body reaches into the bottom opening in the open position and narrows the passage or the passage geometry of the bottom opening. In the closed position of the valve closure part, the adjustment body can in particular be arranged completely in the bottom opening. The adjustment body can thus be lowered together with the valve closure part in the closed position, in which the valve closure part sits on the valve seat and closes the bottom opening in a watertight manner.

Furthermore, a drain basket can be used in the bottom opening, which has a drain section tapering the cross section of the bottom opening. In this way, the passage resulting between the adjustment body and the bottom opening can be narrowed additionally in order to influence the flushing flow.

Furthermore, the drain valve can have an overflow pipe with the valve closure part, wherein the adjustment body can be arranged below the valve closure part on the overflow pipe. In this way, the flushing flow can be changed particularly well. The valve closure part can be disc-shaped, for example in the form of a silicone sealing disc. This can be held on a longitudinal end region of the overflow pipe facing the bottom opening. Thus, the adjustment body can be raised together with the overflow pipe when the drain valve is actuated, so that the adjustment body located in the closed position below the valve closure part is at least partially lifted out of the bottom opening. The adjustment body is only raised so far that it remains at least partially within the bottom opening and there narrows the passage geometry between the water tank or a drain basket inserted into the bottom opening and the adjustment body.

In particular, the adjusting device can have a base body arranged on the overflow pipe. Furthermore, the adjustment body can be held on the base body so as to be adjustable relative to the base body. The base body can serve as a connecting body between the overflow pipe and the adjustment body. In addition to the holding function for the adjustment body, the base body can have a support surface for the valve closure part on the end face facing the valve closure part in order to prevent the valve closure part from turning over due to the water load which acts particularly on the valve closure part in the open position.

Furthermore, the adjusting device can have latching means which are effectively arranged between the adjusting body and the base body. The latching means can be effective in such a way that the height of the adjustment body is held on the base body. In particular, the locking means can have two locking arms arranged on the adjusting body, wherein the locking arms can engage undercuts formed on the base body in a spring-elastic manner. In this way, the adjustment body can be adjusted or snapped into different drain positions, with the locking arms locking in a positive and non-positive manner in the individual drain positions to hold the adjustment body on the base body. In an analogous manner, the latching means can also have, in particular, two latching arms arranged on the base body, wherein the latching arms can engage undercuts formed on the adjusting body in a spring-elastic manner. In the respective locking positions, the adjustment body is held stationary relative to the base body.

As an alternative to the height-adjustable mounting of the adjustment body on the base body by means of the latching means, the adjusting device can have screw means. In particular, the adjustment body and the base body can have mutually corresponding threaded sections. The adjustment body and the base body can thus be screwed to one another in a height-adjustable manner. For example, the adjustment body have an internal thread and the base body has a corresponding external thread. Alternatively, the base body can have an internal thread into which the adjusting body provided with an external thread can be screwed in and out in a height-adjustable manner.

In particular, the adjusting device has loosening means in order to prevent a complete detachment of the adjustment body from the base body when the adjustment body is adjusted into the different drain positions.

Furthermore, the guide means of the adjusting device can be designed in such a way that the adjustment body can be adjusted into the drain position from a longitudinal end of the drain valve facing away from the bottom opening. In particular, the guide means can have a rod which is arranged in the overflow pipe and is connected to the adjusting body. In this way, the adjustment body can be moved from the upper longitudinal end of the drain valve into the individual drain positions. The rod can be guided in the overflow pipe in order to be able to pull the rod up and down easily. Alternatively, the rod can also be moved up and down by rotating it. The rod can in particular be a threadless rod or a threaded rod.

Furthermore, a filling unit can be provided for filling the water tank with rinsing water, the adjusting body being held on a carrier of the filling unit, in particular held vertically adjustable. Such a carrier can be, for example, a height-adjustable partition for a two-quantity control technique of the cistern. Furthermore, the adjusting body can be fastened to a holding rod, which is held in particular in a height-adjustable manner on a stationary housing of the drain valve or the filling unit or the water tank itself.

Furthermore, the valve seat can be a component inserted in the bottom opening. The valve seat can have a central through-hole through which the rinsing water can drain. In the closed position, the valve closure part sits on the valve seat and closes the valve seat and thus also the bottom opening in a watertight manner. In particular, the valve seat can be formed on a conventional drain basket his. In other words, the valve seat can be part of the drain basket. The drain basket is usually inserted in the bottom opening of the water box and sealed against the bottom opening of the water box. The drain basket used in the bottom opening can extend in the direction of the drain valve and at least partially encompass it in the circumferential direction. The drain basket can thus axially cover the travel path of the valve closure part. This means that the valve closure part can move up and down within the drain basket between the open position and the closed position. In principle, the valve closure part can also perform a pivoting movement between the open position and the closed position. The drain basket usually has ribs or struts, in particular transverse and longitudinal struts, which delimit passages between them through which the rinsing water can flow first into the drain basket and then through the valve seat or the bottom opening from the water tank.

In particular, the valve seat can be formed on a drain basket, wherein the adjusting body can be held movably on the drain basket or can be an adjustable component of the drain basket. Thus, the at least one adjustment body of the adjusting device can be designed in the form of at least one movably arranged strut, in particular the transverse and / or longitudinal struts, of the drain basket. The struts can then be adjusted to adjust the rinsing flow in order to disturb the outflowing rinsing water as close as possible to the bottom opening or the valve seat and in this way to change the rinsing flow.

According to a further embodiment of the present invention, it is provided that the adjustment body is arranged in an outlet connection of the water box following the valve seat in the flow direction. In particular, the adjustment body can be held so as to be rotatable in the drainage connection and have at least one passage opening for the rinsing water. By turning the adjustment body, it can be adjusted into the individual drain positions. Furthermore, the adjusting device can have a second adjusting body with at least one second passage opening for the rinsing water. By turning at least one of the adjustment bodies relative to the other adjustment body, the degree of coverage of the two passage openings is changed, as a result of which the passage geometry of the passage changes in the individual Process positions changes. The greater the degree of coverage of the passage openings of the two adjusting bodies, the larger the passage, or the larger the resulting flushing flow, and vice versa. In this way, the purge flow can be changed.

In particular, the through openings of the two adjustment bodies match in shape and position. If the passage openings of the two adjusting bodies are arranged one above the other in alignment, the flushing flow that is set is maximum. If the two adjustment bodies are rotated against each other, the passage geometry of the passage through which the flushing water flows can be reduced, so that a flushing flow that is reduced compared to the maximum achievable flushing flow can be set. In particular, the adjustment bodies can each have a plurality of the passage openings, which are formed distributed on the adjustment bodies in the circumferential direction. In particular, the second adjustment body is held in the drain socket in a rotationally fixed manner. In this way, the flushing flow can be adjusted in a simple manner by rotating the first adjustment body.

Furthermore, the passage openings of the adjustment body can be designed to be uniformly distributed in the circumferential direction. For example, the adjustment bodies can be wheel-shaped or star-shaped. In particular, webs that run radially and delimit the passage openings are narrower than the passage openings when viewed in the circumferential direction, so that when the adjustment bodies are rotated relative to one another, a flow of the flushing water through the passage is always maintained. This avoids that flushing water flowing out is completely retained by the adjustment body, or that the flushing flow becomes zero.

Furthermore, the adjustment body can have means for changing its inner diameter. For example, the adjustment body can be designed in the form of a photographic diaphragm. For this purpose, the adjusting body can have a plurality of lamellae distributed in the circumferential direction, which can be shifted into one another in such a way that the inside diameter becomes larger or smaller. The smaller the inside diameter, the more the flushing water is slowed down or the flushing flow is reduced. Accordingly, the larger the inner diameter, the more The outflowing rinsing water can flow through the adjustment body more freely and is accordingly braked less strongly. This results in a further possibility of setting or changing the flushing flow by changing the passage geometry of the passage.

The passage geometry changed by the adjustment body can in principle have any two or three-dimensional geometric shape. For example, the changed passage geometry lies on the lateral surface of a cone, a truncated cone, a cylinder or a cuboid. The passage can also be formed by a plurality of gaps between the adjusting body on the one hand and the drain valve or the bottom of the water tank on the other hand and / or by cutouts in the adjusting body itself.

In particular, the adjustment body can be adjusted without tools. For example, the adjusting body arranged in the water box can be fastened to a holding rod. Then the installer can easily grasp an upper end of the holding rod through an inspection opening in order to adjust the adjustment body to the desired drain position. Snap-in and / or snap and / or clip connections are particularly suitable for tool-free adjustment. Using the example of the aforementioned photographic diaphragm or the rotatable adjusting body arranged in the drain connector or the two adjusting bodies rotatable relative to one another, the adjusting body can in particular have an adjusting lever or adjusting ring which passes through the drain connector and is sealed with respect to it.

Optical and / or haptic display means are expediently provided for displaying the position and / or orientation of the adjusting body in the flushing flow. In this way, when adjusting the adjustment body, it can be seen in which run position the adjustment body is located. In this respect, the installer can use the display means to adjust the adjustment body to the desired drain position in order to change, in particular enlarge or reduce, the passage geometry of the passage through which the flushing water flows, without having to have a direct view of the adjustment body. The display means can, for example, be a scale, in particular comprise a number scale or a plurality of palpable elevations which are arranged, in particular, equidistantly from one another.

In particular, the cistern arrangement has a flush-mounted cistern for front wall or stud wall installation or a surface-mounted cistern.

In the Figures 1 to 6 a cistern arrangement for flushing a sanitary ware, not shown, according to a first embodiment of the present invention is shown. The cistern arrangement has a water tank 1 for receiving rinsing water, which can be filled with rinsing water via a filling unit 2 in a manner known per se. The filling unit 2 is on one inside the water tank 1 arranged carrier 3 held. The carrier 3 is here as a partition that is vertically displaceable along a longitudinal direction X for one of the DE 10 2004 046 721 B1 known two-quantity control technology trained. Furthermore, the water tank 1 has a bottom opening 4, to which an outlet connection 20 with an outlet 21 at the end connects. The bottom opening 4 is opened by a drain valve 5 and closed watertight. For this purpose, the drain valve 5 has a valve closure part 6, which is between one in the Figure 6 shown open position and a closed position in the Figures 1 and 2 is shown, can be moved linearly up and down along a travel path H extending parallel to the longitudinal axis X. In the closed position, the valve closure part 6 interacts with a valve seat 7, inserted in the bottom opening 4, of a drain basket 25 inserted in the bottom opening 4. In the open position, the valve closure part 6 is lifted off the valve seat 7 and opens the bottom opening 4, so that the rinsing water can flow out through the bottom opening 4 and flush the connected sanitary ware. The drain basket 25 has, in a manner known per se, a plurality of longitudinal struts 26 and transverse struts 27 arranged between the longitudinal struts 26 and connected to them. Between the struts 26, 27, the rinsing water can flow into the drain basket 25 and, in the open position, flow out through the valve seat 7 of the drain basket 25 into the drain connector 20 connected to the sanitary ceramic.

For the variable setting of the flushing flow or the volume flow of the flushing water flowing out through the outlet 21, the cistern arrangement has an adjusting device 8 which is shown in FIG Figure 4 to clarify the structure of which is shown separately. The adjusting device 8 has, for example, a hollow cylindrical adjusting body 9. According to the in the Figure 4 Enlarged view of the adjustment body 9 can have several, for example two, in particular diametrically opposed arranged radially inwardly bent guide openings 24. Likewise, the adjustment body 9 can have a plurality of openings in the form of round or elongated bores or slots. In principle, the adjustment body 9 can also have an angular profile. Furthermore, the adjustment body 9 can have the shape of a shell which is semicircular in cross section and can be adjusted axially and / or radially to the longitudinal axis X. In principle, the adjustment body 9 can also consist of several parts be trained. For example, the adjusting body 9 can have a plurality of shell-like elements, in particular two semicircular shells, which can be adjusted axially and / or radially to the longitudinal axis X. The individual elements of the adjusting body 9 can be arranged in the circumferential direction in an abutting manner or at a distance from one another. In principle, the adjustment body 9 can have any three-dimensional geometric shape, wherein the adjustment body 9 can be formed in one piece or in several parts.

According to the in the Figure 4 The embodiment shown here can be held on guide means by way of example of the adjustment body 9 which is designed here as closed in the circumferential direction. The guide means have an elongated holding rod 10 to which the adjustment body 9 is attached. In the longitudinal direction of the holding rod 10, a plurality of cutouts 11 are provided which are equally distributed over the longitudinal extent. Furthermore, the guide means have a holding plate 12, on which the holding rod 10 and thus also the adjusting body 9 are guided so as to be adjustable in height parallel to the longitudinal axis X. Specifically, a holding tab 13 is formed on the holding plate 12, which is penetrated by the holding rod 10. As soon as one of the recesses 11 of the holding rod 10 overlaps with the holding tab 13, the holding rod 10 detachably latches with the holding plate 12. In this way, the adjusting body 9 is guided and held on the holding plate 12 in a height-adjustable manner.

The in the Figures 1 to 3 Adjustment device 8 shown in the installed state is held by the holding plate 12 on the carrier 3 of the filling valve 2. In the installed state, the holding plate 12 and the holding rod 10 are arranged parallel to the longitudinal axis X and the adjusting body 9 is arranged radially to the longitudinal axis X. It can be seen that an inner radius r _{i of} the hollow cylindrical adjusting body 9 is greater than an outer radius r _{a of} the drain valve 5. The outer radius r _a need not be the maximum outer radius of the drain valve 5. The inner radius r _{i of} the adjusting body 9 should only be greater along the area in which the adjusting body 9 is adjusted in height relative to the drain valve 5 than the drain valve 5 in this area. This is because it has been shown that the adjusting body 9 should be brought as close as possible to the bottom opening 4 or the valve seat 7 in order to adjust the flushing flow. Basically, it is sufficient if the inner radius r _{i of} the adjusting body 9 is greater than an outer radius of the valve closure part 6.

In the Figure 2 it can be seen that the adjusting body 9 is arranged concentrically with the valve seat 7 and engages around the drain valve 5. In principle it is possible and also conceivable that the adjusting body 9 is arranged eccentrically or eccentrically to the valve seat 7. Furthermore, an axial longitudinal extent B of the adjusting body 9 is smaller than an axial distance H between the valve closure part 6 and the valve seat 7 in the open position of the drain valve 5.

In the Figure 5 three different drain positions of the adjustment body 9 are shown in a simplified schematic partial view.

In the Figure 5a the adjusting body 9 is shown in an upper drain position. A cylindrical passage 16a is formed between a lower end face 14 of the drain valve 5 and an upper outer surface 15 of the valve seat 7. The adjustment body 9 is pushed so far up that it does not axially cover the passage 16a. Thus, the flushing water can flow freely through the bottom opening 4 in the open position of the drain valve 5. This results in a high purge flow. The high purge flow corresponds negligibly to the maximum achievable purge flow that would have been achieved with this cistern arrangement if no adjustment body 9 was used.

In the Figure 5b the adjusting body 9 is shown in a middle drain position, in which the adjusting body 9 axially partially covers the cylindrical passage 16a. It can be seen that the passage geometry of the passage has been changed. The rinsing water that is drained off must now flow through a restricted passage. Specifically, the adjustment body 9 moved down in front of the passage results in a passage with an annular gap 16b 'extending radially to the longitudinal axis X and a narrower cylindrical passage gap 16b "extending axially to the longitudinal axis X. The sum of the two surfaces 16b', 16b through which the flushing water flows "is smaller than the original one in the Figure 5a shown cylindrical passage 16a. The result of the narrowed passage geometry of the passage 16b ', 16b "is an average purge flow.

In the Figure 5c the adjustment body 9 is further shifted downwards in the direction of a bottom 17 of the water tank 1. The passage is further narrowed by the adjustment body 9. Specifically, there is a passage with an annular gap 16c 'which extends conically to the longitudinal axis X and a further reduced cylindrical passage gap 16c "which extends axially to the longitudinal axis X. The sum of the two surfaces 16c', 16c" through which the flushing water flows is smaller than the original , in the Figure 5a shown cylindrical passage 16a and smaller than the sum of the in the Figure 5b shown passage geometry 16b ', 16b ". As a result, the passage geometry 16b', 16c", which is narrowed further, results in a low purge flow.

In the Figure 6 is the adjustment body 9, as in the Figure 5b , Shown in the middle drain position, in which the adjusting body 9 axially partially covers the travel path H of the valve closure part 6. To clarify the flow flow of the outflowing rinsing water which results in the open position of the drain valve 5, this is shown in simplified form with arrows S, the flow flow with a view to FIG Figure 6 only on the right half of the Figure 6 is drawn.

A mark 18 is provided on the carrier 3 of the filling valve 2 so that the installer can recognize the drain position of the adjusting body 9 from the outside when looking into the water tank 1. An upper longitudinal end 19 of the holding rod 10 is flush with the marking 18 when the adjustment body 9 is arranged in a predetermined lowest drain position, in which the adjustment body 9 is spaced from the floor 17. For example, the adjustment body 9 in the lowest can be spaced from the floor 17 by approximately 10 millimeters. To adjust the adjustment body 9 without tools, the installer can reach into the water tank 1 through an inspection opening (not shown in more detail) and move the holding rod 10 by pulling the holding rod 10 upwards or pushing it downwards. Furthermore, a number scale can be applied to the holding rod 10, so that when the holding rod 10 is adjusted in height, the installer recognizes together with the marking 18 in which of the drain positions the adjusting body 9 is located.

In the Figure 7 a cistern arrangement for flushing a sanitary ware, not shown, according to a second embodiment of the present invention is shown, components which correspond to the cistern arrangement described above being provided with the same reference numbers.

In contrast to that in the Figures 1 to 6 shown cistern arrangement, the adjusting device 8 is held height adjustable on the drain valve 5. Specifically, a guide rail 22 is arranged on a housing 23 of the drain valve 5, on which the holding rod 10 is movably held. The adjusting body 9 can thus be adjusted into the desired running position by adjusting the holding rod 10.

In the Figures 8 and 9 A cistern arrangement for flushing a sanitary ceramic, not shown, according to a third embodiment of the present invention is shown, components which correspond to one of the above-described embodiments being provided with the same reference numerals.

The adjusting device 28 has a first adjusting body 29 and a second adjusting body 29 ', both adjusting bodies 29, 29' being arranged in the outlet connection 20. The first adjusting body 29 in the flow direction is held so as to be rotatable in the outlet connection 20 and can be adjusted from the outside via a rotary ring 30 which is sealed off from the outlet connection 20. The second adjusting body 29 'following in the direction of flow is inserted in the outlet connection 20 in a rotationally fixed manner.

In the Figure 9 the second adjustment body 29 'is shown as an example. The first adjustment body 29 corresponds to the configuration of the second adjustment body 29 ′, the first adjustment body 29 additionally having the rotating ring 30. It can be seen that the two adjusting bodies 29, 29 'have a spoke-shaped configuration in cross section. This means that the adjustment bodies 29, 29 'have a plurality of radially extending webs 31 which delimit through openings 32 for the rinsing water between them.

In order to change the flushing flow of the flushing water flowing out of the water tank 1 with a defined flushing water quantity through the setting device 28 the rotatable first adjustment body 29 is rotated relative to the fixed second adjustment body 29 ′ via the rotary ring 30 into the desired running position. In this way, the degree of coverage of the passage openings 32 of the adjusting bodies 29, 29 ′ arranged one above the other is changed. In this way, the passage geometry of the passage is changed in the individual drain positions. The greater the degree of coverage of the passage openings 32 of the two adjusting bodies 29, 29 ', the larger the passage, or the greater the resulting rinsing flow, and vice versa. In this way, the purge flow can be changed.

So that the installer can see the set drain position of the first adjusting body 29 from the outside with a view of the drain connector 20, optical and / or haptic display means (not shown in more detail) for displaying the position and / or orientation of the Adjustment body 29 may be provided.

In principle, it is possible and conceivable that at least one of the struts 26, 27 is variably adjustable in order to change the rinsing flow of the rinsing water flowing out through the bottom opening 4.

In the Figures 10 to 16 A cistern arrangement for flushing a sanitary ceramic, not shown, according to a further embodiment of the present invention is shown, components which correspond to one of the above-described embodiments being provided with the same reference numbers.

In the sectional view of the Figure 10 it can be seen that the adjusting device 38 has an adjustment body 39 and a base body 40, the base body 40 being arranged on an overflow pipe 41 of the drain valve 5. The valve closure part 6 is also held on the overflow pipe 41, the base body 40 being releasably connected to the overflow pipe 41 below the valve closure part 6. The base body 40 can, for example, be pushed on, plugged on or screwed onto the longitudinal end of the overflow pipe 41. Here, the base body 40 and the overflow pipe 41 are connected to one another by means of a bayonet lock 42. The base body 40 is approximately tapered to the bottom opening 4, so that the end face of the base body 40 facing the valve closure part 6 has a maximum outer diameter. Thus, the valve closure part 6, which is designed here in the form of an annular silicone sealing disc, can be in the Figure 11 Support the open position shown on the end face of the base body 40. This prevents the silicone sealing disk 6 from folding over due to the water load acting on it.

The adjusting body 39 is of hollow cylindrical design and can be adjusted in height in the form of a sliding ring or telescopically by moving it up and down relative to the base body 40 and thus moved into several drain positions.

To adjust the height of the adjustment body 39 on the base body 40, the adjusting device 38 has latching means 43 which are effective between the adjustment body 39 and the base body 40. Specifically, two locking arms 44 arranged diametrically opposite one another are arranged on the hollow-cylindrical adjusting body 39. The latching arms 44 extend through two receiving slots 45 formed in the base body 40 into the interior of the base body 40. The locking arms 44 have on their radial outer sides a plurality of locking lugs 46, here six locking lugs 46 per locking arm 44, which engage undercuts 47 formed on the base body 40 due to the spring-elastic design of the locking arms 44. Thus, the adjustment body 39 can be adjusted in height relative to the base body 40, or relative to the drain valve 5, in six different drain positions. Furthermore, a retaining lug 48 is formed on the free end of the latching arms 44 facing the drain valve 5, which lugs prevent the adjusting body 39 from being lost towards the bottom opening 4.

In Figures 11 and 12 it can be seen that, in order to increase the stability of the latching arms 44, webs 49 can be formed on the radially inwardly facing outer surfaces, which webs are designed here as triangular webs 49 projecting radially inwards.

In Figure 10 It can be seen that the adjusting device 38 further comprises guide means 50, by means of which the adjusting body 39 can be adjusted in height from a longitudinal end 51 of the drain valve 5 facing away from the bottom opening 4 into the different drain positions determined by the latching lugs 46. Specifically, the guide means 50 have a rod 52 which is arranged in the overflow pipe 41 and is connected to the adjusting body 39 at its lower longitudinal end. For this purpose, two radially oriented retaining webs 53 are arranged at the lower longitudinal end of the rod 52, which are connected to the rod 52 on the radially inner side. The retaining webs 53 are connected radially on the outside to the adjustment body 39, two longitudinal slots open axially downward being formed in the base body 40, through which the retaining webs 53 extend radially outward. At the upper longitudinal end of the rod 52, a holding element 54 is arranged for the clamping reception of the rod 52.

In the Figure 14 the drain valve 5 is shown as a separate assembly. It can be seen that the setting device 38 is arranged on the drain valve 5 and can therefore be inserted and removed from the water tank 1 together with the drain valve 5. This allows a conventional cistern arrangement with a conventional drain valve by exchanging the drain valve with the in Figure 14 drain valve 5 shown can be retrofitted with the adjusting device 38. A conventional drain valve can also be retrofitted with the setting device 38. In the simplest embodiment, the adjusting device 38 then only has the base body 40 and the adjusting body 39, which is retrofitted on the lower longitudinal end of the overflow pipe of a conventional drain valve. The retrofitted variant can also be provided in a particularly simple embodiment of the adjusting device 38 without the guide means 50.

In Figure 10 it can be seen that the drain basket 25 inserted into the bottom opening 4 has an outlet section 55 tapering the cross section of the bottom opening 4

When the flush is actuated, the adjusting body 39 is moved up together with the drain valve 5 and then lowers again together with the drain valve 5. In Figure 11 the drain valve 5 is shown in the open position, in which the valve closure part 6 is lifted off the valve seat 7 and releases the bottom opening 4. In Figure 12 the drain valve 5 is shown in the closed position, in which the valve closure part 6 sits on the valve seat 7 and closes the bottom opening 4 in a watertight manner.

In Figure 11 It can be seen that in the open position of the valve closure part 6, the base body 40 is lifted out of the bottom opening 4 of the water tank 1, the adjusting body 39 remaining partially inside the bottom opening 4 due to the arrangement at the lower longitudinal end of the overflow pipe 41. In principle, the base body 40 could also be arranged at least partially within the bottom opening in the open position.

Characterized in that the adjusting body 39 extends in the open position into the bottom opening 4, or into the drain section 55 tapered by the drain basket 25, the drain opening or the passage geometry for the outflowing rinse water is narrowed. By adjusting the height of the adjusting body 39 relative to the base body 40 or the overflow pipe 41, the depth of the adjusting body 39 with which the adjusting body 39 extends into the bottom opening 4 in the open position can be adjusted. The term depth is understood here to mean the axial length of the axial overlap of the adjusting body 39 with the bottom opening 4. In this way, the adjusting body 39 can be adjusted in six different drain positions, the flushing flow of the defined amount of flushing water flowing out through the bottom opening 4 being dependent on the adjusted drain position of the adjusting body 39. In the in Figure 12 The closed position shown is the base body 40 and the adjustment body 39 within the bottom opening 4. Depending on the set drain position, the adjusting body 39 can also extend beyond the bottom opening 4 into the drain connector 20 connected to the water tank 1.

For easier adjustment of the flushing flow, the adjusting body 39 can be moved between individual flushing processes, in particular between the test flushing processes carried out by an installer, by pulling the rod 52 upward or pushing it downward into one of the, here six, latching positions, or drain positions. During the flushing process, the adjusting body 39 is held stationary relative to the base body 40 or to the drain valve 4.

In principle, instead of the height-adjustable latching means 43, the adjusting body 39 could be screwed to the base body 40 so as to be height-adjustable in a manner not shown, so that a rotational movement of the rod 52 would then transfer the adjusting body 39 into the different running positions. This enables a continuous height adjustment of the adjustment body 39 to be provided.
