EP2660399A1 - Actuation device for a runoff valve of a flushing device - Google Patents

Abstract

The operating device (1) has a motor (4) provided with an output element (5). The output element is connected loosely with a full flush lever (2) or a partial flush lever (3) during movement so as to provide movement of the flush levers against the gravitational force. The partial flush lever and the full flush lever are connected with each other through a coupling element (6) such that the movement of one flush lever driven by the output element is transferred onto the other flush lever that is uncoupled from the output element. An independent claim is included for a cistern arrangement.

Description

TECHNICAL AREA

The present invention relates to an actuating device for an outlet valve of a flushing device for selectively triggering a full-volume flush or a partial flush according to the preamble of claim 1 and a cistern assembly with an actuating device according to claim 10.

STATE OF THE ART

Flushing devices for triggering full-volume flushes and partial flushing are known from the prior art. For example, the shows EP 0 722 020 a rinsing device of the type mentioned EP 0 722 020 a closure body is lifted from a valve seat, then the rinse water from the cistern of the device to be flushed, such as a toilet or urinal can be supplied. The closure body is lifted by two tension elements or levers. One of the two tension elements serves to trigger the partial flush and the other of the two tension elements is used to trigger the Vollmengenspülung. For this purpose, one or the other of the two tension elements must be actuated by an actuating unit. This operation was usually solved to the effect that two tension elements are provided which can be actuated via two operating buttons.

After lifting the closure body, the tension elements move back to the starting position and the closure body is held open by a float. As soon as the water level in the cistern has dropped to a corresponding level, the closing body is flushed over the weight body during the partial flushing process and above the ventilation of the float during the full-flushing process closed.

In summary, it can therefore be said that the release takes place with mechanical means and that the closure then takes place through the drain fitting via floats and / or weight bodies.

The trigger usually has a relatively complex mechanics. This is disadvantageous because of the complexity of the manufacturing effort is relatively high and also the susceptibility to error of installers not professionally mounted elements is also high.

From the EP 1 493 873 In addition, a device is known, which is driven by an electric motor. The electric motor stands in firm connection with the drain valve. The drain valve is opened and the drain valve is closed directly via the servomotor. In this case, the outflow quantity is regulated substantially time-controlled, which has the disadvantage that the desired outflow quantity can not be manipulated manually. Furthermore, this forced coupling has also shown that uncontrolled forces act on the motor during the closing process, which adversely affects its service life.

PRESENTATION OF THE INVENTION

Based on this prior art, the invention has for its object to provide an automated driven, in particular electrically driven, actuator, with which a waste set can be operated as easily as possible. Next, the actuator should be designed as durable as possible with respect to the number of actuations.

Such an object is achieved by the actuating device according to claim 1. Accordingly, an actuating device for actuating a waste fitting of a flushing device for selectively triggering a full flush or a partial flush by lifting a closure body of the drain fitting a Full-quantity rinse lever for triggering a full-volume rinse and a partial-quantity rinse lever for triggering a partial-quantity rinse. The Vollmengenspülhebel is movable from a rest position to a Vollmengenspülposition and the Teilmengenspülhebel is movable from a rest position to a Teilmengenspülposition. The actuating device further comprises a single drive, preferably a motor, in particular an electric motor or a servo motor, with an output element, the output element on the Vollmengenspülhebel or the Teilmengenspülhebel loosely engages and used to move the driven lever. Teilmengenspülhebel and Vollmengenspülhebel are connected to a coupling element with each other, so that the movement of the driven element driven with the scavenging lever on the other from the driven element detached or not directly connected to the driven element flushing lever is transferable.

It is thus driven by the two rinse levers either the Teilmengenspülhebel or Vollmengenspülhebel actively by the drive and the driven element.

The inventive device has the advantage that the movement between the Vollmengenspülhebel and the Teilmengenspülhebel is coupled via the coupling element, whereby a single drive can be arranged. Hierdruch a particularly simple trained device can be provided. Furthermore, the drive always moves from the rest position to only two positions, namely the Teilmengenspülposition and Vollmengenspülposition, which significantly increases the life of the drive.

Another advantage comes from the fact that the output element only loosely engages one of the two rinse levers, that is, not in a firm bond with the same. Preferably, the flushing lever is raised against gravity.

Preferably, the actuating device further comprises a switching element, with which the connection provided by the coupling element between Teilmengenspülhebel and Vollmengenspülhebel can be canceled, wherein the switching element is on the route between rest position and Vollmengenspülposition or between rest position and Teilmengenspülposition. The cancellation of the connection of the two rinse lever has the advantage that one with the two rinse in combination standing waste set can be operated easily.

Upon reaching the rest position, the coupling element engages with the flushing lever, with which the coupling element is not in communication again, so that the connection between the two flushing levers can be restored.

Particularly preferably, the coupling element is designed as a pawl, which is pivotable to the corresponding flushing lever, wherein the other flushing lever without the coupling element has a driving element which enters into a latching connection with the pawl.

During the movement from the rest position into the full-quantity rinsing position or into the partial-quantity rinsing position, the output element can preferably be brought into engagement with the full-quantity rinse lever or the partial quantity rinse lever. In the rest position, the output member of the drive is therefore not in connection with the rinse lever and then attacks after the operation of the rinse lever. Immediately after reaching the desired rinsing position, the driven element is movable into the rest position, whereby the connection between the output element and rinse lever is canceled again. The waste set is kept open via appropriate flushing units, such as a Vollmengenpüleinheit or a Teilmengenpüleinheit until the desired flush volume was removed from the cistern.

Preferably, the output element of the drive engages a molded on the Vollmengenspülhebel or Teilmengenspülhebel lever section.

Preferably, the switching element is provided by a stop on which the coupling element is present during the movement, wherein upon reaching the stop, the connection between Vollmengenspülhebel and Teilmengenspülhebel can be canceled.

A cistern assembly includes an actuator as described above, a cistern having an interior bounding wall and a wall penetrating inlet opening and having a wall penetrating outlet opening with a valve seat and a drain fitting with a in the interior lift the closure opening in a closed position closing closure body, wherein the closure body is movable from the closure position into a rinsing position releasing the outlet opening. The drain fitting comprises a Vollmengenspülhebel operable Vollmengenpüleinheit operable with the Teilmengenspülhebel Teilmengenpüleinheit, which flushing units are in communication with the closure body. Upon actuation of the Teilmengenspülung the Vollmengenpüleinheit is bridged or not operated and when operating the Vollmengenspülung the Teilmengenpüleinheit is bridged or not operated.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the Fig. 1 an actuator 1 for the operation of a drain fitting of a flushing device is shown. The actuating device 1 serves for the selective triggering of a full flush or a partial flush. During the rinsing process, a closure body of a waste fitting arranged in a cistern is raised by a valve seat surrounding an outlet opening so that rinsing water can flow out of the cistern. The closure body is thus lifted from a closure position closing the outlet opening into a rinsing position and is moved again from the rinsing position to the closure position after the rinsing water has been removed.

The actuator 1 essentially comprises a Vollmengenspülhebel 2 for triggering a Vollmengenspülung and a Teilmengenspülhebel 3 to trigger a Teilmengenspülung. With the full flush, a larger amount of water is removed from the cistern than with the partial flush.

The actuated by the actuator 1 to be operated waste comprises, as in the FIGS. 6 to 8 shown for the actuation of the closure body 51 operable with the Vollmengenspülhebel 2 Vollmengenpüleinheit 53 and actuated with the Teilmengenspülhebel 3 Teilmengenpüleinheit 54. The flushing units 53 and 54 are in communication with the closure body 51 and hold the closure body 51 as long as in the flushing position to the corresponding Rinse water was removed from the cistern.

The Vollmengenspülhebel 2 is movable from a rest position to a Vollmengenspülposition. During the movement of the Vollmengenspülhebels 2 in the Vollmengenspülposition the closure body 51 of the drain assembly 50 is lifted from the valve seat 52 from the closed position to the scavenging position. The Vollmengenpüleinheit 53 then holds the closure body 51 in the flushing position until the corresponding amount of flushing water has flowed out of the cistern.

The Teilmengenspülhebel 3 is also movable from a rest position to a Teilmengenspülposition. In the partial flush, the closure body 51 of the drain fitting 50 is also raised from its valve seat 52 from the closed position to the flushing position. In analogy to the full-flush, the Teilmengenpüleinheit 54 of the drain fitting holds the closure body 51 in the flushing position until the corresponding amount of flushing water has flowed out of the cistern.

The actuating device 1 further comprises a single drive 4, preferably in the form of a motor 4, with an output element 5. The output element 5, which is driven by the motor 4, acts on either the Vollmengenspülhebel 2 or the Teilmengenspülhebel 3 and serves to move the driven Rinse lever 2, 3. In the present embodiment, the output member 5 engages a lever portion 8, which extends from the Teilmengenspülhebel 3, at. The output element 5 thus acts here on the Teilmengenspülhebel 3.

The expression "attack" or "attack loosely" in this context means that there is no firm connection between the output element 5 and the corresponding flushing lever 2, 3. Rather, the output element 5 only serves to raise the corresponding flushing lever 2, 3 from its rest position to the corresponding flushing position. There is no firm connection between connecting element 5 and flushing lever 2, 3rd

The output element 5 is brought into motion with the Vollmengenspülhebel 2 or with the Teilmengenspülhebel 3 when moving from the rest position in the Vollmengenspülposition or in the Teilmengenspülposition. In the rest position, the output element 5 is not in engagement with the corresponding rinse levers, which has the advantage that the rinse in an emergency can be easily triggered by hand. Immediately after reaching the desired rinsing position, the output element 5 is moved back to the rest position.

The drive can be designed in various ways. Preferably, it is an electric motor 4, in particular a servomotor. Alternatively, the drive can also be designed otherwise, for example as a mechanical, pneumatic or hydraulic drive. In the following, the term "motor" is used to describe the drive, which includes all types of suitable drives.

The engine 4 substantially travels two positions, namely, the partial purge position and the full-purge position, from the rest position. After reaching the corresponding flushing position, the motor 4 then moves back to the rest position. The motor 4 is controlled via corresponding communication elements. The communication elements are connected to an actuating plate, not shown in connection. The user actuates the actuator plate and a signal is generated via the communication lines to the motor 4 out. Depending on the operation of the actuator plate, the signal is then associated with the partial flush or the full-flush.

With regard to the water level seen in a cistern, the two rinse levers are at different heights, preferably the Vollmengenspülhebel is above the Teilmengenspülhebels. Thus, the two flushing positions can be distinguished from each other and it is possible to prioritize the flushing.

The Teilmengenspülhebel 3 and the Vollmengenspülhebel 2 are connected to a coupling element 6 in connection, so that the movement of the driven with the driven element 5 flushing lever 2, 3 on the other from the driven element 5 detached and not directly driven flushing lever 2, 3 is transferable.

In the present embodiment, as already mentioned above, the output element 5 engages the subset purge lever 3. Consequently, the movement is transmitted from the output element 5 to the Teilmengenspülhebel 3 and from this then via the coupling element 6 to the Vollmengenspülhebel 2. Further, a single motor is provided due to the coupling between the two flushing levers 2, 3. Consequently, therefore, an output element 5 raises both rinse lever 2, 3 and it can be triggered with this one element and the motor 4, both the full amount and the part quantity. As a result, the mechanical structure of an actuator is substantially simplified.

In operation, which is then below in connection with the Fig. 2 to 5 will be explained in more detail, the engine 4 moves substantially two positions. On the one hand, the Teilmengenspülposition and on the other hand, the Vollmengenspülposition. Shortly after reaching the corresponding flushing position, the motor 4 then returns to the starting position and the waste set is kept open via the Vollmengenpüleinheit 53 and the Teilmengenpüleinheit 54 until the corresponding amount of flushing water has drained from the cistern. In other words, this means that the motor 4 while the operation of the two flushing lever 2, 3 is used, but then does not serve to keep the pop-up over the time required for the appropriate flushing open. This keeping open the drain fitting or is provided exclusively by the drain fitting and its units 53 and 54.

Further, the actuating device 1 comprises a switching element 7. With the switching element 7, the coupling provided by the coupling element 6 between Teilmengenspülhebel 3 and Vollmengenspülhebel 2 can be canceled. The switching element 7 can be on the route between rest position and Vollmengenspülposition or between rest position and Teilmengenspülposition. The removal of the connection between Teilmengenspülhebel 3 and Vollmengenspülhebel 2 has the advantage that the two rinse, so the Vollmengenspülhebel 2 and the Teilmengenspülhebel 3, are formed separable, whereby the functionality of the actuator 1 is considerably improved. This is then related to the description of the Fig. 2 to 9 explained in detail.

The coupling element 6 is arranged in this embodiment between the Vollmengenspülhebel 2 and the Teilmengenspülhebel 3. Preferably, the coupling element 6 is connected to the Teilmengenspülhebel 3 in connection. The coupling element 6 is preferably rotatably or pivotally mounted to the corresponding flushing lever.

The switching element 7 is preferably provided by a stop 9. At this stop 9 is the coupling element 6 in the movement, wherein upon reaching the Stop 9 the connection between Vollmengenspülhebel 2 and Teilmengenspülhebel 3 can be canceled.

Of the Fig. 1 can be further recognized that the device comprises a storage element 10 here. The bearing element 10 essentially serves to receive the corresponding elements of the actuating device 1. The bearing element 10 thus provides a receptacle for the pivotable mounting of the Vollmengenspülhebels 2 and Teilmengenspülhebels 3, a receptacle 11 for the motor 4 and the switching element 7 and the stopper 9 ready , Vollmengenspülhebel 2 and Teilmengenspülhebel 3 are rotatably mounted about a common center axis M in a storage lug 12.

Furthermore, the storage element 10 comprises an optional hooking portion 13, with which the storage element 10 can be suspended in a cistern.

In the present embodiment, the function of the Vollmengenspülhebels and the other flushing lever was assigned the function of Teilmengenspülhebels the one rinse lever. The functions can also be reversed, so that the designated above as Vollmengenspülhebel rinsing lever is provided for the subset and vice versa.

Based on Fig. 2 to 5 Now, the operation of the actuator 1 will be explained.

In the Fig. 2a and the Fig. 2b , All elements are in the rest position. The output element 5 is outside the range of movement of the two rinse 2, 3. In the Fig. 2a In addition, the Teilmengenspülhebel 3 is shown partially cut in the region of the coupling element 6, so that the view of the coupling element 6 is free.

The coupling element 6 is, as already explained, with the Teilmengenspülhebel 3 in connection and engages here on a driving element 14, which is in communication with the Vollmengenspülhebel 2, a, so that the two levers 2, 3 are coupled together when moving. This is shown in more detail in detail Z, where it can be well recognized that the coupling element 6 here a driving portion 15th has, which is in accordance with the driving element 14 in conjunction, or engages with the driving element 14, as soon as the two levers 2, 3 move from the rest position into the rinsing position.

In the Fig. 2a In addition, it can be recognized that the flushing lever, which is not in communication with the coupling element 6, has a link 16. This gate 16 serves the coupling element 6 as feedback after actuation. The coupling element 6 will come back into engagement with the entrainment element 14 via the link 16 during the movement from the scavenging position into the rest position.

In the Fig. 3a and 3b the position of the output element 5 is shown shortly after flushing. The driven by the motor 4 drive element 5 has already pivoted to the lever portion 8 and attacks on this lever section 8. Here, the output element 5 raises the lever portion 8 and thus Vollmengenspülhebel 2 and also the Teilmengenspülhebel 3 are raised accordingly. As explained above, the lever portion 8 is formed here on the Teilmengenspülhebel 3 and the movement of the Teilmengenspülhebel 3 is transmitted via the coupling element 6 on the Vollmengenspülhebel 3.

In detail Y the Fig. 3a can also continue to be recognized that the coupling element 6 is in engagement with the driving element 14 of the Vollmengenspülhebels 2. The movement is transmitted accordingly via this.

In the Fig. 4a. and 4b the output lever 5 is shown in the Vollmengenspülposition. The Vollmengenspülhebel 2 has thus reached its end position, so the Vollmengenspülposition 2. With regard to the waste fitting with the closure body is hereby mentioned that the Vollmengenpüleinheit 53 has now also reached the specific position for the Vollmengenspülung position and thus the closure body is arranged correspondingly spaced from the valve seat. The closure, so the return movement of the closure body on the valve seat, it is preferably level controlled, that is, when the level of the rinse water in the cistern has reached a predetermined lower level, the closure body moves automatically to the valve seat.

Immediately after reaching the Vollmengenspülposition the output lever 5 is moved back to the rest position.

This is on the one hand due to the formation of the drain set possible because the Teilmengenpüleinheit were not operated due to their arrangement or because the said elements were bridged. On the other hand, as can be clearly seen in the figures, the Vollmengenspülhebel 2 with respect to the water level in the cistern with an offset above the Teilmengenspülhebels 3. This offset has the effect that the Vollmengenspülung takes precedence over the Teilmengenspülung because when reaching the Vollmengenspülung not the Teilmengenspülposition has been reached.

In the Fig. 5a and 5b the release of the partial flush is explained accordingly.

On the way to the Teilmengenspülposition the coupling element 6 comes into contact with the switching element 7. Here, the coupling between Vollmengenspülhebel 2 and Teilmengenspülhebel 3 is repealed accordingly. In detail W the Fig. 5a This can be well recognized. The Vollmengenspülhebel 2 returns immediately after the decoupling of the two rinse lever 2, 3 in the rest position. The Teilmengenspülhebel 3 is then moved further in the Teilmengenspülposition. The Teilmengenpüleinheit 54 is then actuated accordingly and keeps the closure body 51 in the upper position until the Teilmengenspülung was done accordingly. The Teilmengenspülhebel 3 and the output element 5 move but immediately after reaching the Teilmengenspülposition back to the corresponding rest position.

With regard to the full-volume flushing unit 53, it should be noted that it is bridged accordingly or not switched on or not actuated when the partial flushing is triggered. In other words, when driving over the Vollmengenspülposition by the Vollmengenspülhebel 2, the Vollmengenspüleinheit 53 are switched off or bridged at the drain fitting 50 accordingly.

Based on FIGS. 6 to 8 Now, an exemplary pop-up waste 50, which with the Actuator described above is actuated, described in more detail. The drain fitting 50 may also be designed differently. In the FIGS. 6 to 8 the elements of the actuator are shown schematically.

In the FIG. 6 the waste set 50 is shown in the closed position. The closure body 51 is in contact with the valve seat 52 of the cistern 55 and is in the closed position.

With reference to the FIGS. 6 and 7 the full flush is explained. The Vollmengenspülhebel 2 engages in a tab 56 of the Vollmengenpüleinheit 53. About the Vollmengenpüleinheit 53, which is in communication with the closure body 51, then the closure body 51 is lifted from the valve seat 52. In the FIG. 7 this will be clarified. When the purge is triggered, the engine 4 is actuated, and thus the output member 5 is in the Vollmengenspülposition after FIG. 7 pivoted. The output element 5 acts on the Teilmengenspülhebel 3 and the coupling element 6, the movement is transmitted to the Vollmengenspülhebel 2. The Vollmengenspülhebel 2 then lifts on the Vollmengenpüleinheit 53, the closure body 51 at. Immediately after reaching the Vollmengenspülposition the output element 5 and the Vollmengenspülhebel 2 is pivoted back to the rest position and the Vollmengenpüleinheit 53 holds the closure body 51 in the scavenging position. For this purpose, the Vollmengenpüleinheit 53 may for example comprise a coupled to a float 57 latching element. The latching element provides for the closure body 51 in the Vollmengenspülposition a stop against the movement toward the valve seat 52 ready. As soon as the water in the cistern under the float 56 has dropped, its buoyancy force drops through the water and the latch member is actuated, so that the stop for the closure body 51 is omitted and this moves to the closed position.

In the full-flush, the Teilmengenpüleinheit 53 is raised equally. The stroke of the Teilmengenpüleinheit 53 is too small here, however, that the Teilmengenpüleinheit 53 could be actuated or switched on. If the stroke were greater in the full-flush, the Teilmengenpüleinheit 53 would not be switched on.

Based on FIGS. 6 and 8 the partial purge is explained. The Teilmengenspülhebel 3 engages in a tab 58 of the Teilmengenpüleinheit 54. About the Teilmengenpüleinheit 54, which is in communication with the closure body 51, then the closure body 51 is lifted from the valve seat 52. In the FIG. 8 this will be clarified. When the purge is triggered, the motor 4 is actuated and thus the output element 5 is in the Teilmengenspülposition after FIG. 8 pivoted. The output element 5 acts on the Teilmengenspülhebel 3 and the coupling element 6, the movement is also transmitted to the Vollmengenspülhebel 2. Upon reaching the switching element 7 and the stop 9, the coupling between Vollmengenspülhebel 2 and Teilmengenspülhebel 3 is repealed. The Teilmengenspülhebel 3 is further moved by the output member 5 in the Teilmengenspülposition and the Vollmengenspülhebel 2 moves automatically back to the rest position. The Vollmengenpüleinheit 53 is not activated or switched here, although the Vollmengenspülposition is passed in the movement of the closure body 51. Immediately after reaching the Teilmengenspülposition the output element 5 is pivoted back to the rest position and the Teilmengenpüleinheit 54 holds the closure body 51 in the rinsing position. For this purpose, the Teilmengenpüleinheit 54 may include, for example, a 60 coupled to a float 59 latching. The latching element provides a stop against the movement in the direction of the valve seat 52 for the closure body 51 in the Teilmengenspülposition. As soon as the water in the cistern has sunk below the float 59, its buoyancy force drops through the water and the latching element is actuated, so that the stop for the closure body 51 is removed and this moves into the closed position.

The float 59 could also be a closing weight, in which case the function of the device would be slightly different.

For the elimination of Vollmengenpüleinheit 53 and the Teilmengenpüleinheit 54, the flushing units 53, 54, for example, provided with a switching member which engages a preferably stationary in the cistern 55 counterpart, so that the corresponding flushing is not actuated.

Vollmengenspülung and Teilmengenspülung the waste set can also be based on the device EP 0 722 020 be executed.
