Definitions
- the present invention relates to a cistern arrangement for flushing a sanitary ceramic according to the preamble of claim 1.
- 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.
- a cistern which has a plurality of partitions, so that a plurality of chambers are formed.
- a through opening is provided in a partition, which can be closed or opened by a pivotable slide.
- a plurality of openings are provided in a partition, which can be closed by plugs.
- 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.
- 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.
- 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.
- the flushing rimless toilet bowl has a cover which is fastened in front of it after the flushing water distributor has been inserted.
- 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.
- 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.
- the drain valve interacting with the valve seat must be removed or subsequently reassembled due to the narrow interior of the concealed cistern.
- 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.
- flush 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.
- the adjustment body changes a passage geometry of a passage through which the flushing water flows.
- the smaller the passage geometry that is, the more the adjustment body narrows the passage, the lower the resulting purge flow.
- 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.
- the first flushing stream can be a high flushing stream, for example 2.4 liters per second
- the second flushing stream can be a lower flushing stream, for example 2.0 liters per second.
- the adjustment body can also be moved into additional 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.
- 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.
- 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.
- 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.
- 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.
- the flushing flow is changed by moving the adjustment body into one of the drain positions.
- 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.
- 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.
- the adjustment body in one of the drain positions, 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.
- the setting device can represent an independent structural unit.
- 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.
- 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.
- the setting device can be moved up and down together with the valve closure part.
- the adjustment body is held stationary relative to the valve closure part.
- the cistern arrangement can comprise exactly one adjustment body.
- the adjustment body can be made in one piece or in several parts.
- 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.
- 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.
- the adjustment body can be arranged to be movable within the water box.
- the adjustment body can be reached by the installer via an inspection opening of the water box and moved into the individual drain positions.
- 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.
- the adjustment body 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.
- guide and / or holding means are provided which hold the adjustment body in the water tank.
- 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.
- the adjustment body in the water tank can be moved up and down in a simple manner, in particular linearly.
- the height of the adjustment body can also be adjusted by a rotary movement.
- 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.
- the adjustment body can be displaceably guided in the water tank.
- a guide rail can be attached to the water box, on which the adjustment body can be moved in a guided manner.
- the adjustment body is held stationary by the guide and / or holding means, at least during a flushing process, relative to the flushing flow.
- 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.
- 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.
- 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.
- an inner radius of the adjusting body can be larger, equal to or smaller than an outer radius of the valve closure part.
- 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.
- the adjustment body can be designed interrupted in the circumferential direction.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the adjusting device can have a base body arranged on the overflow pipe.
- 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.
- 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.
- 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.
- 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.
- 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.
- the adjusting device can have screw means.
- 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.
- the adjustment body have an internal thread and the base body has a corresponding external thread.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- a carrier can be, for example, a height-adjustable partition for a two-quantity control technique of the cistern.
- 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.
- 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.
- the valve seat can be formed on a conventional drain basket his.
- 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.
- valve closure part can move up and down within the drain basket between the open position and the closed position.
- 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.
- 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.
- 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.
- the adjustment body is arranged in an outlet connection of the water box following the valve seat in the flow direction.
- 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.
- the adjusting device can have a second adjusting body with at least one second passage opening for the rinsing water.
- 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.
- the adjustment bodies can each have a plurality of the passage openings, which are formed distributed on the adjustment bodies in the circumferential direction.
- 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.
- the passage openings of the adjustment body can be designed to be uniformly distributed in the circumferential direction.
- the adjustment bodies can be wheel-shaped or star-shaped.
- 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.
- the adjustment body can have means for changing its inner diameter.
- the adjustment body can be designed in the form of a photographic diaphragm.
- 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.
- 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.
- the adjustment body can be adjusted without tools.
- 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.
- 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.
- 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.

- 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 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.
- the degree of coverage of the passage openings 32 of the adjusting bodies 29, 29 ′ arranged one above the other is changed.
- 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.

- 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.

- a holding element 54 is arranged for the clamping reception of the rod 52.
- 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.

- 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.
- 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.

Description
Die vorliegende Erfindung betrifft eine Spülkastenanordnung zur Spülung einer Sanitärkeramik nach dem Oberbegriff des Anspruchs 1.The present invention relates to a cistern arrangement for flushing a sanitary ceramic according to the preamble of
Grundsätzlich können bei der Spülung einer Sanitärkeramik, beispielsweise eines Toilettenbeckens oder eines Urinalbeckens, Wasserspritzer über die Sanitärkeramik austreten. Am Beispiel des Toilettenbeckens muss gemäß der europäischen Norm EN 997 allerdings sowohl eine flächige Ausspülung des Toilettenbeckens gewährleistet als auch ein Austreten von Spritzern, kurz Überspritzen, vermieden werden. Dies führt vor allem bei sogenannten spülrandlosen Toilettenbecken, bei denen kein umlaufender Spülrand vorgesehen ist, zu einer erhöhten Anforderung an die Präzision bei der Herstellung der Sanitärkeramik.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.
Zudem kommt hinzu, dass am Markt unterschiedliche Spülkästen verfügbar sind, die ihrerseits unterschiedliche Spülströme aufweisen. So weisen vor allem ältere Spülkästen regelmäßig Spülströme im Bereich von 3 Litern pro Sekunde und neuere Spülkästen Spülströme von 2 bis 2,4 Litern pro Sekunde auf. Dabei wird der maximale Spülstrom bereits kurz nach Beginn des Spülvorgangs, etwa nach 0,2 Sekunden, erreicht. Anschließend nimmt der Spülstrom aufgrund des sinkenden Wasserpegels im Spülkasten über den Spülvorgang kontinuierlich ab. Somit kann vor allem beim Betrieb der spülrandlosen Toilettenbecken der zu Beginn des Spülvorgangs schnell anliegende maximale Spülstrom zum Überspritzen führen. Allerdings zeigt es sich problematisch, bei Installation der Sanitärkeramik den Spülstrom der unterschiedlichen Spülkästen an die anzuschließenden Toilettenbecken, Urinalbecken oder dergleichen anzupassen, um ein Überspritzen zu vermeiden. Insofern wird vor allem für die spülrandlosen Toilettenbecken der diversen Hersteller eine Vielzahl unterschiedlicher Spülkästen am Markt vorgehalten, die den für das jeweilige Toilettenbecken empfohlenen maximalen Spülstrom nicht überschreiten. Dabei darf die Sanitärkeramik auch nicht mit einem zu niedrigen Spülstrom durchströmt werden, um stets zu gewährleisten, dass die Sanitärkeramik sowie die nachfolgenden Abwasserleitungen ausreichend gespült werden.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.

Allerdings müssen mehrere der bekannten Spülstromdrosseln mit jeweils einer unterschiedlich starken Spülstromdrosselwirkung bereitgestellt werden, um den Spülstrom eines angeschlossenen Spülkastens an das Toilettenbecken anpassen zu können. Darüber hinaus muss zur Einstellung des Spülstromes stets der gesamte Spülwasserverteiler entnommen werden, um die rückseitig, beziehungsweise in Flussrichtung eingangsseitig, am Grundkörper des Spülwasserverteilers gehaltene Spüldrossel auszutauschen. Dadurch gestaltet sich die Einstellung des Spülstromes an das Toilettenbecken aufwendig. Des Weiteren ist die Ausstattung des Toilettenbeckens mit dem bekannten Spülstromverteiler nur dann möglich, wenn werkseitig ein entsprechender Bauraum im Toilettenbecken vorgesehen wurde.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.
Aus dem Prospekt "TECE-Spültechnik, Technische Informationen", 1-2015 der TECE GmbH ist bekannt, dass durch Einsetzen einer Spülstromdrossel in einem Ventilsitz eines in einem Unterputz-Spülkasten eingesetzten Ablaufkorbes der Spülstrom verändert werden kann. Hierzu wird ein Drosselset mit vier verschiedenen Drosseln bereitgestellt, die jeweils einen unterschiedlichen Innendurchmesser aufweisen. Wenn der Spülstrom des Unterputz-Spülkastens für die angeschlossene Sanitärkeramik zu hoch ist und das Spülwasser überspritzt, kann der Spülstrom durch Einsetzen einer der Drosseln in den Ventilsitz reduziert werden. Dabei ist der Spülstrom ohne eine Drossel am höchsten und entsprechend am niedrigsten, wenn die Drossel mit dem kleinsten Innendurchmesser im Ventilsitz eingesetzt ist.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.
Um eine der Drosseln im Ventilsitz einsetzen oder gegen eine andere Drossel mit einer unterschiedlichen Drosselwirkung austauschen zu können, muss aufgrund des beengten Innenraums des Unterputz-Spülkastens das mit dem Ventilsitz zusammenwirkende Ablaufventil demontiert bzw. anschließend wieder montiert werden. Zudem muss ein Drosselset mit mehreren Drosseln unterschiedlicher Drosselwirkung bereitgestellt werden, um den für die angeschlossene Sanitärkeramik passenden Spülstrom einstellen zu können.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.
Aufgabe der vorliegenden Erfindung ist es, eine Spülkastenanordnung bereitzustellen, die auf einfache und kostengünstige Weise an eine Sanitärkeramik angepasst werden kann, um ein Überspritzen zu vermeiden.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.
Die Aufgabe ist erfindungsgemäß bei einer Spülkastenanordnung zur Spülung einer Sanitärkeramik gemäß der eingangs genannten Art dadurch gelöst, dass die Einstellvorrichtung am Ablaufventil angeordnet ist, wobei beim Betätigen der Spülung der Verstellkörper zusammen mit dem Ablaufventil hochbewegt wird und sich anschließend zusammen mit dem Ablaufventil wieder absenkt. Der Verstellkörper ist relativ zum Wasserkasten bewegbar angeordnet und in mehrere Ablaufpositionen verstellbar, wobei der Spülstrom der aus dem Wasserkasten abfließenden definierten Spülwassermenge von der Ablaufposition des Verstellkörpers abhängig ist, respektive beeinflusst wird. Der Verstellkörper ist am Ablaufventil höhenverstellbar gehalten, wobei der Spülstrom entsprechend veränderbar bzw. einstellbar ist.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.
Unter dem Begriff des Spülstroms wird ein Volumenstrom, konkret das Volumen des Spülwassers pro Zeiteinheit durch einen Auslass der Spülkastenanordnung, insbesondere den Auslass eines Ablaufstutzens eines Spülkastens, verstanden.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.
Erfindungsgemäß ist somit vorgesehen, den Spülstrom durch einen bewegbaren Verstellkörper einzustellen, wobei der Verstellkörper in wenigstens zwei voneinander unterschiedliche Ablaufpositionen bewegt werden kann. In den einzelnen Ablaufpositionen wird durch den Verstellkörper eine Durchlassgeometrie eines vom abfließenden Spülwasser durchströmten Durchlasses verändert. Regelmäßig gilt, dass je kleiner die Durchlassgeometrie ist, das heißt je mehr der Verstellkörper den Durchlass verengt, desto geringer ist der sich ergebende Spülstrom. Im Umkehrschluss ist der Spülstrom regelmäßig dann maximal, wenn der Einfluss des Verstellkörpers auf den Durchlass marginal ist. Somit stellt sich in der einen Ablaufposition aufgrund einer vom Verstellkörper beeinflussten ersten Durchlassgeometrie ein erster Spülstrom und in der zweiten Ablaufposition aufgrund einer veränderten zweiten Durchlassgeometrie ein zweiter Spülstrom ein. Beispielsweise kann der erste Spülstrom ein hoher Spülstrom, beispielsweise 2,4 Liter pro Sekunde, und der zweite Spülstrom ein geringerer Spülstrom, beispielsweise 2,0 Liter pro Sekunde, sein. Neben den beiden vorgenannten Ablaufpositionen kann der Verstellkörper auch in weitere Ablaufpositionen bewegt werden.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.
Durch die variable Verstellbarkeit des Verstellkörpers in die verschiedenen Ablaufpositionen kann der Spülstrom verändert, beziehungsweise eingestellt werden. Dabei kann der Verstellkörper zwischen einzelnen Spülvorgängen, insbesondere zwischen den von einem Installateur durchgeführten Probespülvorgängen, in eine der Ablaufpositionen bewegt werden. Während der Spülvorgänge kann der an sich bewegbare, beziehungsweise verstellbare Verstellkörper relativ zum Wasserkasten oder einem im Wasserkasten angeordneten Bauteil einer herkömmlichen Spülkastenanordnung, beispielsweise dem Ablaufventil oder einem Füllventil, ortsfest gehalten. Somit kann der Verstellkörper auch als Hinderniskörper oder Widerstandskörper bezeichnet werden, der die Strömung in der Spülkastenanordnung verändert, respektive beeinflusst. Das abfließende Spülwasser wird in seinem ungestörten Fluss, der sich ohne den Verstellkörper einstellen würde, gestört, da der Verstellkörper die vom Spülwasser durchströmte Durchlassgeometrie verändert. Auf diese Weise greift der Verstellkörper gestaltend in die Spülströmung ein, um den Spülstrom zu verändern.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.
Beispielsweise kann der Verstellkörper in seiner Lage und/oder Ausrichtung zur Spülströmung verändert werden. Dabei kann die Bewegung des Verstellkörpers gestuft oder stufenlos erfolgen. Dadurch kann der Installateur den Spülstrom auf einfache Weise durch den in der Spülkastenanordnung eingesetzten beziehungsweise eingebauten Verstellkörper in die einzelnen Ablaufpositionen verstellen, ohne diesen hierzu entnehmen oder gegen einen anderen Verstellkörper austauschen zu müssen. Somit muss der einmal in der Spülströmung angeordnete Verstellkörper im Betrieb der Sanitäranordnung und vor allem zur Einstellung des Spülstromes nicht mehr entnommen werden.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.
Es versteht sich, dass der Bezug auf das Spülwasser und die Spülströmung lediglich dem besseren Verständnis der räumlichen Anordnung der Einstellvorrichtung in der Spülkastenanordnung dient, da der Wasserkasten nur im Betrieb mit Spülwasser befüllt ist und das Spülwasser entsprechend nur im Betrieb in der Offenstellung des Ablaufventils aus der Bodenöffnung abfließen kann.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.
Durch Verstellung des Verstellkörpers in eine der Ablaufpositionen wird der Spülstrom verändert. Allerdings ist nicht vorgesehen, dass der Verstellkörper derart ausgestaltet und positioniert ist, dass durch den Verstellkörper beziehungsweise die Einstellvorrichtung Spülwasser im Wassertank zurückgehalten wird. Somit bleibt das für den Spülvorgang zur Verfügung stehende Gesamtvolumen des Spülwassers, das heißt die definierte Spülwassermenge, unverändert. Die definierte Spülwassermenge kann beispielsweise bei einem Spülkasten mit einer bekannten Zweimengenspültechnik eine kleine Spülwassermenge von circa 3 Litern oder bei der Anwahl der Vollspülung eine große Spülwassermenge von circa 4 bis 9 Litern sein. Der Spülvorgang kann bei einem Spülkasten mit einer bekannten Start-Stop-Funktion unterbrochen werden, wodurch die definierte Spülwassermenge manuell durch Betätigung der Stop-Taste verändert werden kann. Allerdings wird durch die Zweimengenspültechnik oder die Start-Stop-Funktion lediglich die Spülwassermenge verändert, wobei der Spülstrom unverändert bleibt.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.
Der Spülstrom kann reduziert werden, indem der Verstellkörper die sich ohne den Verstellkörper ergebende durchströmte Fläche des Durchlasses teilweise überdeckt, respektive verengt, ohne diesen vollständig zu versperren. Im Umkehrschluss kann der Spülstrom erhöht werden, wenn der Verstellkörper derart verstellt wird, dass die ursprüngliche Durchlassgeometrie des Durchlasses, die sich ohne den Verstellkörper ergeben würde, wieder erreicht wird. Beispielsweise kann der Verstellkörper in einer der Ablaufpositionen derart entfernt vom Durchlass angeordnet oder derart in seiner Erstreckung verkleinert oder derart reibungsarm parallel zur Strömungsrichtung des abfließenden Spülwassers ausgerichtet sein, dass der Einfluss des Verstellkörpers auf das durch den Durchlass abfließende Spülwasser marginal ist. Dabei wird eine Veränderung des Spülstroms durch den Einfluss des Verstellkörpers von maximal 5% gegenüber einem sich ohne den Verstellkörper ergebenden Spülstrom noch als marginal betrachtet.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.
Weiterhin kann die Einstellvorrichtung eine unabhängige Baueinheit darstellen. Insbesondere ist die Einstellvorrichtung eine vom Ablaufventil funktional und baulich getrennte Einheit. Die Einstellvorrichtung kann beispielsweise lösbar am Ablaufventil befestigt sein. Die Einstellvorrichtung wird üblicherweise vom Installateur zwischen zwei Probespülvorgängen verstellt, um den Spülstrom zu reduzieren oder zu erhöhen. Dagegen bewegt sich das Ablaufventil üblicherweise nur während der Spülvorgänge. Somit funktioniert die Einstellvorrichtung unabhängig von sich bewegenden Bauteilen des Ablaufventils, beispielsweise dem sich zwischen der Offenstellung und der Schließstellung bewegenden Ventilverschlussteil des Ablaufventils. Ebenso kann die Einstellvorrichtung zusammen mit dem Ventilverschlussteil hoch- und herunterbewegt werden. Insbesondere ist der Verstellkörper relativ zum Ventilverschlussteil ortsfest gehalten.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.
Des Weiteren kann die Spülkastenanordnung genau den einen Verstellkörper umfassen. Dabei kann der Verstellkörper einteilig oder mehrteilig ausgebildet sein. Es ist prinzipiell auch denkbar und möglich, dass die Spülkastenanordnung mehrere der einteilig oder mehrteilig ausgebildeten Verstellkörper aufweist. Beispielsweise kann wenigstens einer der Verstellkörper im Wassertank und/oder wenigstens einer der Verstellkörper im Ablaufstutzen des Wassertanks angeordnet sein und/oder es können zwei Verstellkörper gegeneinander drehbar sein. Der besseren Lesbarkeit halber wird der zumindest eine Verstellkörper kurz mit der Verstellkörper bezeichnet. Wenn es auf genau den einen Verstellkörper ankommt, wird entsprechend darauf hingewiesen.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.
Gemäß einer Ausführungsform der vorliegenden Erfindung kann der Verstellkörper innerhalb des Wasserkastens bewegbar angeordnet sein. Somit kann der Verstellkörper über eine Revisionsöffnung des Wasserkastens vom Installateur erreicht und in die einzelnen Ablaufpositionen bewegt werden.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.
Vorteilhafterweise ist der Verstellkörper innerhalb des Wasserkastens höhenverstellbar gehalten. Dabei wird der Einfluss des Verstellkörpers auf den Spülstrom größer, je näher der Verstellkörper an die Bodenöffnung des Wasserkastens oder den Ventilsitz angeordnet ist, und vice versa. Üblicherweise hebt das Ablaufventil das Ventilverschlussteil entlang eines Verfahrweges zwischen der Schließstellung und der Offenstellung linear nach oben vom Ventilsitz ab. Bei einem herkömmlichen Spülkasten ohne Verstellkörper würde dann das Spülwasser in der Offenstellung zwischen dem Ablaufventil und dem Ventilsitz durch die Bodenöffnung abfließen. Durch die Höhenverstellung kann der Verstellkörper beispielsweise radial beabstandet zum Ventilverschlussteil hoch- und runterbewegt werden. Wenn der Verstellkörper soweit nach oben bewegt ist, dass sich der Verstellkörper nicht mit dem Verfahrweg des Ventilverschlussteils axial überlagert, übt der Verstellkörper keinen oder allenfalls einen marginalen Effekt auf den sich einstellenden Spülstrom aus. Wenn dagegen der Verstellkörper weiter nach unten verstellt wird, wird der Durchlass zwischen dem Ablaufventil und dem Ventilsitz teilweise überdeckt. Dadurch ergibt sich eine veränderte Durchlassgeometrie des Durchlasses, insbesondere wird der Durchlass verkleinert, wodurch die Durchflussrate, das heißt der Spülstrom, reduziert wird. Weiterhin kann der Verstellkörper auch in der Offenstellung des Ventilverschlussteils zumindest teilweise in der Bodenöffnung angeordnet sein, um den Durchlass der Bodenöffnung zu verändern, respektive gegenüber dem ursprünglichen Durchlass der Bodenöffnung wahlweise zu verengen.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.
Insbesondere sind Führungs- und/oder Haltemittel vorgesehen, die den Verstellkörper im Wasserkasten halten. Auf diese Weise kann der Spülstrom bei Installation der Spülkastenanordnung durch den Installateur einfach und reproduzierbar eingestellt werden. Der Verstellkörper kann beispielsweise dadurch höhenverstellbar im Wasserkasten gehalten sein, indem er an einem Führungs- und/oder Haltemittel in Form eines länglichen Stabs befestigt ist, der an einem ortsfesten Bauteil der Spülkastenanordnung, beispielsweise einer Wandung des Wasserkastens oder einem Gehäuse des Ablaufventils, gehalten ist. Der Stab kann beispielsweise geclipst, lösbar arretiert oder mit einer manuell bedienbaren Kunststoffschraube an einem ortsfesten Bauteil innerhalb des Wasserkastens oder am Wasserkasten selbst befestigt sein. Dadurch kann der Verstellkörper in dem Wasserkasten auf einfache Weise insbesondere linear hoch-und runterbewegt werden. Ebenso kann der Verstellkörper auch durch eine Drehbewegung in der Höhe verstellt werden. Beispielsweise kann der Verstellkörper an einem unteren Ende einer Drehspindel befestigt sein, die wiederum am Wasserkasten, Ablaufventil oder an einem ortsfesten Bauteil gehalten sein kann. Weiterhin kann der Verstellkörper im Wasserkasten geführt verschiebbar sein. Beispielsweise kann am Wasserkasten eine Führungsschiene befestigt sein, an der der Verstellkörper geführt verschoben werden kann. Insbesondere ist der Verstellkörper durch die Führungs- und/oder Haltemittel zumindest während eines Spülvorgangs relativ zur Spülströmung ortsfest gehalten.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.
Um in der Offenstellung kein Spülwasser im Wasserkasten durch den Verstellkörper zurückzuhalten, soll der Verstellkörper stets von einem Boden des Wasserkastens beabstandet sein. Beispielsweise kann eine axiale Längserstreckung des Verstellkörpers kleiner sein als ein axialer Abstand zwischen dem sich in der Offenstellung befindlichen Ventilverschlussteil und dem Ventilsitz. Somit wird gewährleistet, dass der Verstellkörper den ursprünglichen Durchlass in keiner Stellung vollständig verdeckt und stets Spülwasser durch den Durchlass abfließen kann.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.
Des Weiteren kann der Verstellkörper formstabil und nur in der Lage und/oder Ausrichtung zur Spülströmung verstellbar sein. Der Verstellkörper kann in Umfangsrichtung geschlossen ausgebildet sein. Der Verstellkörper kann hohlzylindrisch oder kegel- oder kegelstumpfartig ausgebildet sein. Der Verstellkörper kann eine geschlossene Mantelfläche aufweisen. Alternativ kann der Verstellkörper eine löchrige und/oder geschlitzte Mantelfläche aufweisen, sodass zumindest eine Teilmenge des abfließenden Spülwassers den Verstellkörper durchströmen kann, bevor es durch den Durchlass durchströmt. Dies kann ebenfalls zu einer Verlangsamung des Spülwassers und somit zu einer Reduzierung des Spülstroms führen. Insbesondere kann ein Innenradius des Verstellkörpers größer, gleich oder kleiner als ein Außenradius des Ventilverschlussteils sein. Des Weiteren kann der Verstellkörper konzentrisch zum Ventilsitz angeordnet sein. Wenn der Innendurchmesser des Verstellkörpers größer ist als der des Ablaufventils, dann kann der Verstellkörper das Ablaufventil umgreifen und axial zum Ablaufventil hoch und runterbewegt werden. Zweckmäßigerweise ist der Verstellkörper am Ablaufventil verstellbar gehalten. Weiterhin kann der Verstellkörper in Umfangsrichtung unterbrochen ausgebildet sein. Beispielsweise kann der Verstellkörper mehrere in Umfangsrichtung verteilt angeordneten Elemente aufweisen. Die Elemente können zum Beispiel über Führungs- und/oder Haltemittel relativ zueinander gehalten sein.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.
Des Weiteren kann der Verstellkörper an einem der in einem Wasserkasten eines herkömmlichen Spülkastens üblicherweise vorgesehenen Bauteile gehalten sein. Somit können herkömmliche Spülkasten auf einfache Weise mit der Einstellvorrichtung nachgerüstet werden.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.
Insbesondere kann der Verstellkörper zumindest in der Offenstellung des Ventilverschlussteils zumindest teilweise innerhalb der Bodenöffnung des Wasserkastens angeordnet sein. Auf diese Weise greift der Verstellkörper in der Offenstellung in die Bodenöffnung und verengt den Durchlass, respektive die Durchlassgeometrie der Bodenöffnung. Der Verstellkörper kann in der Schließstellung des Ventilverschlussteils insbesondere vollständig in der Bodenöffnung angeordnet sein. Somit kann der Verstellkörper in der Schließstellung, in der das Ventilverschlussteil auf dem Ventilsitz aufsitzt und die Bodenöffnung wasserdicht verschließt, zusammen mit dem Ventilverschlussteil abgesenkt werden.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.
Weiterhin kann in der Bodenöffnung ein Ablaufkorb eingesetzt sein, der einen den Querschnitt der Bodenöffnung verjüngenden Ablaufabschnitt aufweist. Auf diese Weise kann der sich zwischen den Verstellkörper und der Bodenöffnung ergebende Durchlass zusätzlich verengt werden, um den Spülstrom zu beeinflussen.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.
Des Weiteren kann das Ablaufventil ein Überlaufrohr mit dem Ventilverschlussteil aufweisen, wobei der Verstellkörper unterhalb des Ventilverschlussteils am Überlaufrohr angeordnet sein kann. Auf diese Weise kann der Spülstrom besonders gut verändert werden. Das Ventilverschlussteil kann scheibenförmig ausgebildet sein, beispielsweise in Form einer Silikondichtscheibe. Diese kann an einem der Bodenöffnung zugewandten Längsendbereich des Überlaufrohrs gehalten sein. Somit kann der Verstellkörper beim Betätigen des Ablaufventils zusammen mit dem Überlaufrohr angehoben werden, sodass der sich in der Schließstellung unterhalb des Ventilverschlussteils befindliche Verstellkörper aus der Bodenöffnung zumindest teilweise herausgehoben wird. Dabei wird der Verstellkörper nur soweit angehoben, dass dieser zumindest teilweise innerhalb der Bodenöffnung verbleibt und dort die Durchlassgeometrie zwischen dem Wasserkasten bzw. einem in die Bodenöffnung eingesetzten Ablaufkorbes und dem Verstellkörper verengt.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.
Insbesondere kann die Einstellvorrichtung einen am Überlaufrohr angeordneten Basiskörper aufweisen. Weiterhin kann der Verstellkörper relativ zum Basiskörper verstellbar am Basiskörper gehalten sein. Der Basiskörper kann als Verbindungskörper zwischen dem Überlaufrohr und dem Verstellkörper dienen. Neben der Haltefunktion für den Verstellkörper kann der Basiskörper an der dem Ventilverschlussteil zugewandten Stirnseite eine Stützfläche für das Ventilverschlussteil aufweisen, um ein Umschlagen des Ventilverschlussteils aufgrund der besonders in der Offenstellung auf das Ventilverschlussteil einwirkenden Wasserlast zu verhindern.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.
Weiterhin kann die Einstellvorrichtung Rastmittel aufweisen, die zwischen dem Verstellkörper und dem Basiskörper wirksam angeordnet sind. Die Rastmittel können dabei derart wirksam sein, dass der Verstellkörper höhenverstellbar am Basiskörper gehalten ist. Insbesondere können die Rastmittel zwei am Verstellkörper angeordnete Rastarme aufweisen, wobei die Rastarme am Basiskörper ausgebildete Hinterschneidungen federelastisch hintergreifen können. Auf diese Weise kann der Verstellkörper in verschiedene Ablaufpositionen verstellt, respektive eingerastet werden, wobei zur Halterung des Verstellkörpers am Basiskörper die Rastarme in den einzelnen Ablaufpositionen form- und kraftschlüssig verrasten. In analoger Weise können die Rastmittel auch insbesondere zwei am Basiskörper angeordnete Rastarme aufweisen, wobei die Rastarme am Verstellkörper ausgebildete Hinterschneidungen federelastisch hintergreifen können. In den jeweiligen Raststellungen ist der Verstellkörper relativ zum Basiskörper ortsfest gehalten.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.
Alternativ zu der höhenverstellbaren Halterung des Verstellkörpers am Basiskörper mittels der Rastmittel kann die Einstellvorrichtung Schraubmittel aufweisen. Insbesondere können der Verstellkörper und der Basiskörper einander korrespondierende Gewindeabschnitte aufweisen. Somit können der Verstellkörper und der Basiskörper höhenverstellbar miteinander verschraubt sein. Beispielsweise können der Verstellkörper ein Innengewinde und der Basiskörper ein korrespondierendes Außengewinde aufweisen. Alternativ kann der Basiskörper ein Innengewinde aufweisen, in welches der mit einem Außengewinde versehene Verstellkörper höhenverstellbar rein- und rausgeschraubt werden kann.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.
Insbesondere weist die Einstellvorrichtung Verliermittel auf, um ein vollständiges Lösen des Verstellkörpers vom Basiskörper beim Verstellen des Verstellkörpers in die verschiedenen Ablaufpositionen zu verhindern.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.
Weiterhin können die Führungsmittel der Einstellvorrichtung derart ausgebildet sein, dass der Verstellkörper von einem von der Bodenöffnung abgewandten Längsende des Ablaufventils aus in die Ablaufposition verstellbar ist. Insbesondere können die Führungsmittel eine im Überlaufrohr angeordnete Stange aufweisen, die mit dem Verstellkörper verbunden ist. Auf diese Weise kann der Verstellkörper vom oberen Längsende des Ablaufventils aus in die einzelnen Ablaufpositionen bewegt werden. Die Stange kann im Überlaufrohr geführt sein, um die Stange auf einfache Weise Hochziehen und Runterdrücken zu können. Alternativ kann die Stange auch durch eine Drehbewegung hoch und runterbewegt werden. Die Stange kann insbesondere eine gewindelose Stange oder eine Gewindestange sein.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.
Weiterhin kann eine Fülleinheit zur Befüllung des Wasserkastens mit Spülwasser vorgesehen sein, wobei der Verstellkörper an einem Träger der Fülleinheit gehalten, insbesondere höhenverstellbar gehalten ist. Ein solcher Träger kann beispielsweise eine höhenverschiebbare Trennwand für eine Zweimengensteuertechnik des Spülkastens sein. Weiterhin kann der Verstellkörper an einem Haltestab befestigt sein, der an einem ortsfesten Gehäuse des Ablaufventils oder der Fülleinheit oder dem Wassertank selbst insbesondere höhenverstellbar gehalten ist.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.
Weiterhin kann der Ventilsitz ein in der Bodenöffnung eingesetztes Bauteil sein. Der Ventilsitz kann eine zentrale Durchgangsbohrung aufweisen, durch die das Spülwasser abfließen kann. In der Schließstellung sitzt der Ventilverschlussteil auf dem Ventilsitz auf und verschließt den Ventilsitz und somit auch die Bodenöffnung wasserdicht. Insbesondere kann der Ventilsitz an einem herkömmlichen Ablaufkorb ausgebildet sein. Mit anderen Worten kann der Ventilsitz ein Bestandteil des Ablaufkorbes sein. Der Ablaufkorb ist üblicherweise in der Bodenöffnung des Wasserkastens eingesetzt und gegenüber der Bodenöffnung des Wasserkastens abgedichtet. Der in der Bodenöffnung eingesetzte Ablaufkorb kann sich in Richtung des Ablaufventils erstrecken und dieses zumindest teilweise in Umfangsrichtung umgreifen. Somit kann der Ablaufkorb den Verfahrweg des Ventilverschlussteils axial überdecken. Das heißt, das Ventilverschlussteil kann sich innerhalb des Ablaufkorbes zwischen der Offenstellung und der Schließstellung hoch- und runterbewegen. Grundsätzlich kann das Ventilverschlussteil auch eine Schwenkbewegung zwischen der Offenstellung und der Schließstellung durchführen. Der Ablaufkorb weist üblicherweise Rippen beziehungsweise Streben, insbesondere Quer- und Längsstreben, auf, die zwischen sich Durchlässe begrenzen, durch die das Spülwasser zunächst in den Ablaufkorb und anschließend durch den Ventilsitz, respektive die Bodenöffnung aus dem Wasserkasten ausströmen kann.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.
Insbesondere kann der Ventilsitz an einem Ablaufkorb ausgebildet sein, wobei der Verstellkörper am Ablaufkorb bewegbar gehalten oder ein verstellbares Bauteil des Ablaufkorbes sein kann. Somit kann der wenigstens eine Verstellkörper der Einstellvorrichtung in Form zumindest einer bewegbar angeordneten Strebe, insbesondere der Quer- und/oder Längsstreben, des Ablaufkorbes ausgebildet sein. Zur Einstellung des Spülstromes können dann die Streben verstellt werden, um das abfließende Spülwasser möglichst nah an der Bodenöffnung beziehungsweise dem Ventilsitz zu stören und auf diese Weise den Spülstrom zu verändern.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.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung ist vorgesehen, dass der Verstellkörper in einem in Flussrichtung dem Ventilsitz nachfolgenden Ablaufstutzen des Wasserkastens angeordnet ist. Insbesondere kann der Verstellkörper im Ablaufstutzen drehend bewegbar gehalten sein und wenigstens eine Durchtrittsöffnung für das Spülwasser aufweisen. Durch Drehen des Verstellkörpers ist dieser in die einzelnen Ablaufpositionen verstellbar. Weiterhin kann die Einstellvorrichtung einen zweiten Verstellkörper mit wenigstens einer zweiten Durchtrittsöffnung für das Spülwasser aufweisen. Durch Verdrehen zumindest eines der Verstellkörper relativ zum anderen Verstellkörper wird der Überdeckungsgrad der beiden Durchtrittsöffnungen verändert, wodurch sich die Durchlassgeometrie des Durchlasses in den einzelnen Ablaufpositionen ändert. Je größer der Überdeckungsgrad der Durchtrittsöffnungen der beiden Verstellkörper ist, desto größer ist der Durchlass, respektive desto größer ist der sich ergebende Spülstrom, und vice versa. Auf diese Weise kann der Spülstrom verändert werden.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.
Insbesondere stimmen die Durchtrittsöffnungen der beiden Verstellkörper in Form und Position überein. Wenn die Durchtrittsöffnungen der beiden Verstellkörper fluchtend übereinander angeordnet sind, ist der sich einstellende Spülstrom maximal. Wenn die beiden Verstellkörper gegeneinander verdreht werden, kann die Durchlassgeometrie des vom Spülwasser durchströmten Durchlasses verkleinert werden, sodass sich ein gegenüber dem maximal erreichbaren Spülstrom reduzierter Spülstrom einstellen lässt. Insbesondere können die Verstellkörper jeweils mehrere der Durchtrittsöffnungen aufweisen, die an den Verstellkörpern in Umfangsrichtung verteilt ausgebildet sind. Insbesondere ist der zweite Verstellkörper drehfest im Ablaufstutzen gehalten. Auf diese Weise kann der Spülstrom durch Drehen des ersten Verstellkörpers auf einfache Weise eingestellt werden.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.
Weiterhin können die Durchtrittsöffnungen der Verstellkörper in Umfangsrichtung gleichmäßig verteilt ausgebildet sein. Beispielsweise können die Verstellkörper radförmig oder sternförmig ausgebildet sein. Insbesondere sind radial verlaufende und die Durchtrittsöffnungen begrenzende Stege in Umfangsrichtung betrachtet schmaler ausgebildet als die Durchtrittsöffnungen, sodass beim Verdrehen der Verstellkörper relativ zueinander stets ein Durchfluss des Spülwassers durch den Durchlass aufrechterhalten bleibt. Somit wird vermieden, dass abfließendes Spülwasser durch die Verstellkörper vollständig zurückgehalten wird, respektive, dass der Spülstrom zu Null wird.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.
Des Weiteren kann der Verstellkörper Mittel zur Veränderung seines Innendurchmessers aufweisen. Beispielsweise kann der Verstellkörper in Form einer fotografischen Blende ausgebildet sein. Hierzu kann der Verstellkörper mehrere in Umfangsrichtung verteilte Lamellen aufweisen, die so ineinander verschoben werden können, dass der Innendurchmesser größer oder kleiner wird. Je kleiner der Innendurchmesser ist, desto mehr wird das abfließende Spülwasser verlangsamt, beziehungsweise der Spülstrom reduziert. Entsprechend gilt, dass je größer der Innendurchmesser ist, desto ungehinderter kann das abfließende Spülwasser den Verstellkörper durchströmen und wird entsprechend weniger stark abgebremst. Dadurch ergibt sich eine weitere Möglichkeit, den Spülstrom durch Veränderung der Durchlassgeometrie des Durchlasses einzustellen beziehungsweise zu verändern.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.
Die durch den Verstellkörper veränderte Durchlassgeometrie kann grundsätzlich jede zwei oder dreidimensionale geometrische Form aufweisen. Beispielsweise liegt die veränderte Durchlassgeometrie auf der Mantelfläche eines Konus, eines Kegelstumpfes, eines Zylinders oder eines Quaders. Dabei kann der Durchlass auch durch mehrere sich zwischen dem Verstellkörper einerseits und dem Ablaufventil beziehungsweise dem Boden des Wassertanks andererseits ergebende Spalte und/oder durch Aussparungen im Verstellkörper selbst gebildet sein.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.
Insbesondere ist der Verstellkörper werkzeuglos verstellbar. Beispielsweise kann der im Wasserkasten angeordnete Verstellkörper an einem Haltestab befestigt sein. Dann kann der Installateur auf einfache Weise durch eine Revisionsöffnung hindurch ein oberes Ende des Haltestabes greifen, um den Verstellkörper in die gewünschte Ablaufposition zu verstellen. Zur werkzeuglosen Verstellung eignen sich vor allem Rast- und/oder Schnapp- und/oder Clipverbindungen. Am Beispiel der vorgenannten fotografischen Blende oder dem im Ablaufstutzen angeordneten drehbaren Verstellkörper oder den beiden relativ zueinander verdrehbaren Verstellkörpern kann der Verstellkörper insbesondere über einen den Ablaufstutzen durchgreifenden und gegenüber diesem abgedichteten Verstellhebel oder Verstellring aufweisen.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.
Zweckmäßigerweise sind optische und/oder haptische Anzeigemittel zur Anzeige der Stellung und/oder Ausrichtung des Verstellkörpers in der Spülströmung vorgesehen. Auf diese Weise kann beim Einstellen des Verstellkörpers erkannt werden, in welcher Ablaufposition sich der Verstellkörper befindet. Insofern kann der Installateur durch die Anzeigemittel den Verstellkörper in die gewünschte Ablaufposition verstellen, um die Durchlassgeometrie des vom Spülwasser durchströmten Durchlasses zu verändern, insbesondere vergrößern oder verkleinern, ohne dabei einen direkten Blick auf den Verstellkörper haben zu müssen. Die Anzeigemittel können beispielsweise eine Skala, insbesondere eine Zahlenskala oder mehrere tastbare Erhebungen umfassen, die insbesondere äquidistant zueinander angeordnet sind.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.

Damit der Installateur beim Blick in den Wasserkasten 1 von außen die Ablaufposition des Verstellkörpers 9 erkennen kann, ist an dem Träger 3 des Füllventils 2 eine Markierung 18 vorgesehen. Ein oberes Längsende 19 des Haltestabes 10 schließt mit der Markierung 18 bündig ab, wenn der Verstellkörper 9 in einer vorgegebenen untersten Ablaufposition, in der der Verstellkörper 9 vom Boden 17 beabstandet ist, angeordnet ist. Beispielsweise kann der Verstellkörper 9 in der untersten mit etwa 10 Millimetern vom Boden 17 beabstandet sein. Zur werkzeuglosen Verstellung des Verstellkörpers 9 kann der Installateur durch eine nicht näher dargestellte Revisionsöffnung in den Wasserkasten 1 greifen und den Haltestab 10 bewegen, in dem der Haltestab 10 nach oben gezogen oder nach unten gedrückt wird. Weiterhin kann auf dem Haltestab 10 eine Zahlenskala aufgebracht sein, sodass der Installateur beim Höhenverstellen des Haltestabes 10 zusammen mit der Markierung 18 erkennt, in welcher der Ablaufpositionen sich der Verstellkörper 9 befindet.A

Die Einstellvorrichtung 28 weist einen ersten Verstellkörper 29 und einen zweiten Verstellkörper 29' auf, wobei beide Verstellkörper 29, 29' im Ablaufstutzen 20 angeordnet sind. Der in Flussrichtung erste Verstellkörper 29 ist im Ablaufstutzen 20 drehend bewegbar gehalten und kann über einen gegenüber dem Ablaufstutzen 20 abgedichteten Drehring 30 von außen verstellt werden. Der in Flussrichtung nachfolgende zweite Verstellkörper 29' ist im Ablaufstutzen 20 drehfest eingesetzt.The adjusting

Um den Spülstrom der aus dem Wasserkasten 1 mit einer definierten Spülwassermenge abfließenden Spülwassers durch die Einstellvorrichtung 28 zu verändern, wird der drehbare erste Verstellkörper 29 relativ zum feststehenden zweiten Verstellkörper 29' über den Drehring 30 in die gewünschte Ablaufposition gedreht. Auf diese Weise wird der Überdeckungsgrad der Durchtrittsöffnungen 32 der übereinander angeordneten Verstellkörper 29, 29' verändert. Auf diese Weise wird die Durchlassgeometrie des Durchlasses in den einzelnen Ablaufpositionen verändert. Je größer der Überdeckungsgrad der Durchtrittsöffnungen 32 der beiden Verstellkörper 29, 29' ist, desto größer ist der Durchlass, respektive desto größer ist der sich ergebende Spülstrom, und vice versa. Auf diese Weise kann der Spülstrom verändert werden.In order to change the flushing flow of the flushing water flowing out of the
Damit der Installateur mit Blick auf den Ablaufstutzen 20 von außen die eingestellte Ablaufposition des ersten Verstellkörpers 29 erkennen kann, können am Drehring 30 und/oder außen am Ablaufstutzen 20 nicht näher gezeigte optische und/oder haptische Anzeigemittel zur Anzeige der Stellung und/oder Ausrichtung des Verstellkörpers 29 vorgesehen sein.So that the installer can see the set drain position of the first adjusting

Zur Höhenverstellung des Verstellkörpers 39 am Basiskörper 40 weist die Einstellvorrichtung 38 Rastmittel 43 auf, die zwischen dem Verstellkörper 39 und dem Basiskörper 40 wirksam sind. Konkret sind an dem hohlzylindrisch ausgebildeten Verstellkörper 39 zwei einander diametral gegenüberliegend angeordnete Rastarme 44 angeordnet. Die Rastarme 44 erstrecken sich durch zwei im Basiskörper 40 ausgebildete Aufnahmeschlitze 45 in das Innere des Basiskörpers 40 hinein. Die Rastarme 44 weisen an deren radialen Außenseiten mehrere übereinander angeordnete Rastnasen 46, hier sechs Rastnasen 46 je Rastarm 44, auf, die am Basiskörper 40 ausgebildete Hinterschneidungen 47 aufgrund der federelastischen Ausgestaltung der Rastarme 44 hintergreifen. Somit kann der Verstellkörper 39 relativ zum Basiskörper 40, respektive relativ zum Ablaufventil 5 in sechs verschiedene Ablaufpositionen höhenverstellt werden. Weiterhin sind an dem zum Ablaufventil 5 gewandten freien Ende der Rastarme 44 jeweils eine Haltenase 48 angeformt, die ein Verlieren des Verstellkörpers 39 zur Bodenöffnung 4 hin verhindern.To adjust the height of the

Dadurch, dass sich der Verstellkörper 39 in der Offenstellung in die Bodenöffnung 4, respektive in den vom Ablaufkorb 25 verjüngten Ablaufabschnitt 55 hinein erstreckt, wird die Ablauföffnung, respektive die Durchlassgeometrie für das abfließende Spülwasser verengt. Durch Höhenverstellen des Verstellkörpers 39 relativ zum Basiskörper 40, respektive zum Überlaufrohr 41, kann die Tiefe des Verstellkörpers 39, mit der sich der Verstellkörper 39 in der Offenstellung in die Bodenöffnung 4 hinein erstreckt, eingestellt werden. Unter dem Begriff Tiefe wird hier die axiale Länge der axialen Überdeckung des Verstellkörpers 39 mit der Bodenöffnung 4 verstanden. Auf diese Weise kann der Verstellkörper 39 in hier sechs verschiedene Ablaufpositionen verstellt werden, wobei der Spülstrom der durch die Bodenöffnung 4 abfließenden definierten Spülwassermenge von der eingestellten Ablaufposition des Verstellkörpers 39 abhängig ist. In der in
Zur einfacheren Einstellung des Spülstromes kann der Verstellkörper 39 zwischen einzelnen Spülvorgängen, insbesondere zwischen den von einem Installateur durchgeführten Probespülvorgängen, durch nach oben Ziehen oder nach unten Drücken der Stange 52 in eine der, hier sechs, Raststellungen, respektive Ablaufpositionen bewegt werden. Während der Spülvorgänge ist der Verstellkörper 39 relativ zum Basiskörper 40 respektive zum Ablaufventil 4 ortsfest gehalten.For easier adjustment of the flushing flow, the adjusting
Grundsätzlich könnte der Verstellkörper 39 statt der höhenverstellbaren Rastmittel 43 in nicht gezeigter Weise mit dem Basiskörper 40 höhenverstellbar verschraubt sein, sodass dann eine Drehbewegung der Stange 52 den Verstellkörper 39 in die verschiedenen Ablaufpositionen überführen würde. Dadurch kann eine stufenlose Höhenverstellung des Verstellkörpers 39 bereitgestellt werden.In principle, instead of the height-adjustable latching means 43, the adjusting
