Description

Water discharge device for a cistern of a WC.

The invention relates to a device of water discharge for a toilet cistern, with controls independent to optionally release the download of a certain amount of water of discharge.

The water discharge devices of this type, which are also called water discharge devices of two quantities are known, for example, from the application for European patent EP 0 723 050 A1 and WO patent application 92/01842.

A European patent application describes a two-quantity water discharge device that uses a usual discharge valve in WC tanks with which at raise the body of the discharge valve remains raised a valve plate of a valve seat found in the discharge outlet of the tank base, and is maintained raised at least one float by pushing action vertical until the cistern is completely empty. To close the discharge valve ahead of time for a certain amount smaller discharge water, that is, before the tank is have emptied, two floats are planned, of which one is fixedly attached and the other detachably with the body of The discharge valve. By releasing the large amount of water from discharge, both floats are attached to the valve body Download Through the vertical thrust of both floats, the valve plate remains lifted from the valve seat until the entire amount of discharge water has been released. In the case of releasing the smallest amount of water from discharge, a float separates from the body of the discharge valve during the water discharge process and retained in this position of rest by means of a mechanical system of hitch until the end of the water discharge process, so that only the thrust vertical of a float keeps the body of the discharge valve in the raised state. Due to the reduced vertical thrust, the plate of the valve already rests on the valve seat before the discharge of the entire amount of discharge water, and close the discharge valve after discharge of a certain partial amount of discharge water. This download device of water of two quantities is in its structure very complicated and prone to breakdowns.

In the case of the solution according to the request of WO 92/01842, the different vertical thrust of the body of the discharge valve in the case of the release of an amount major or minor discharge water is controlled by a bell of load that can be filled with water, fixedly connected with the discharge valve body, which, depending on whether start the water discharge process and after lifting the Valve plate The valve seat can penetrate or not air from outside in the charging hood, the valve body of discharge or remains heavy due to the water load of the charging bell and, therefore, prematurely closes the valve discharge, or increases the vertical thrust due to the air entering and, therefore, the discharge valve is kept open until it is has discharged all the discharge water contained in the cistern. The Air supply to the hood is done through a tube flexible spiral, which leads from inside the hood loading to the outside of the tank. There it is, combined with the release button to lift the valve discharge, a vent valve. This one is always open in the resting position. Therefore, when filling the tank, the bell it can always work full of water, because the air that exists eventually in the bell can be evicted out through of the tube. For the release of the entire amount of water from discharge, in the case of this water discharge device, it press a rocker lever in one direction, by means of which only the discharge valve body is raised and, without However, the ventilation valve remains open. With this guy of release, water also escapes from the charging bell in case of a decrease in the water level in the cistern and is replaced by air, which flows subsequently to the charging bell through the open vent valve and flexible tube. Therefore increases the vertical thrust of the discharge valve body and closes the discharge valve only after all of it has been discharged the amount of water present in the cistern. If the lever swingarm is operated in the direction of the "small amount", there is also a closing of the ventilation valve, in addition to an elevation of the discharge valve body. Therefore, in the If the water level in the tank drops, the water will is in the discharge hood, and the body valve plate of the discharge valve loaded in this way, close the valve discharge before the entire amount of water has been discharged Download

This solution is also relatively complicated. in its structure due to the mechanics necessary for the combination of the release button with the ventilation valve. The tube flexible air between the vent valve located on the lid of the cistern and the top side of the discharge bell either It is able to meet the continuous mechanical effort, so that This solution is also relatively prone to breakdowns.

Therefore, the invention is based on the task of create a water discharge device for a toilet cistern with independent controls to release the download of a certain amount of water from the discharge water, which does not It is complicated in its structure and is not prone to breakdowns.

The task is solved with a device water discharge with the characteristics of the claim of protection 1. Advantageous embodiments of the invention are subject to dependent claims 2 to 11.

The following will explain in detail the invention by means of two embodiments together with figures 1 to 6.

Figure 1 shows a first form of embodiment of a water discharge device according to the invention for a cistern of a WC in rest position;

Figure 2 shows the discharge device of water according to the invention shown in figure 1, in the case of a release of large amount of discharge water;

Figure 4 shows a second form of embodiment of a water discharge device according to the invention in rest position;

Figure 5 shows the discharge device of water according to the invention shown in figure 4, in the case of release of the small amount of discharge water; Y

Figure 6 shows the second form of embodiment of the invention shown in figures 4 and 5 in a partial view in perspective.

Figure 1 shows the device for water discharge according to the invention in rest position.

A plate 2 of the valve of a body 1 of the discharge valve rests on a seat 3 of the valve e prevents the discharge of discharge water 4 from a cistern (no shown). Around the upper area of the valve body 1 of discharge, a container 7 of water is fixedly arranged fundamentally void, open at the bottom. Because of a valve 13 ventilation, always open in the resting position, in the area wall of the water container 7 facing upwards and which it comprises a ventilation opening 8, as well as a lever 12 rotating with a butterfly valve 10 arranged next to it, in if the tank is filled, the air that is eventually in the water container 7 it is pushed out to through the vent opening 8, so that the container 7 of water is completely filled with water in the position of repose.

In case of AG release, shown in the Figure 2, of the large amount of discharge water, body 1 of the discharge valve is dragged up by the control corresponding (not shown) for the large amount of water from discharge, and the plate 2 of the seat valve 3 of the valve. This discharges the discharge water from the cistern, whereby the water level W falls in the cistern. With the lowering of the water level W in the cistern, the water found in the water container 7 because the air L atmospheric can then circulate through valve 13 of open ventilation. This increases the total vertical thrust of the body 1 of the discharge valve and it keeps floating until the tank has been completely emptied, and plate 2 of the valve sits again on the valve seat 3 and it close the discharge valve for the new tank load, load that is controlled by a feed valve.

As already stated, the water container 7 it is completely filled again with water also in the case of a new load because the valve 3 ventilation is always open in the rest position, through which it is evicted all the air L that is in the water container.

In the case of the AK release, shown in the Figure 3, of the small amount of discharge water, the control corresponding (not shown) for the minor amount of water from discharge pulls a pull rod 11 arranged laterally and parallel to the body 1 of the discharge valve. This rod 11 of traction is movably placed in body 1 of the discharge valve or in water container 7, parallel to the shaft of the body 1 of the discharge valve, so that first moves upwards relative to the discharge valve body without drag with it to body 1 of the discharge valve and, with this, for example, by means of a traction flange 21, which protrudes laterally, which is attached to the lower part of the arm 9 of the swivel lever 12 of the vent valve 13 drags up the arm 9 of the rotating lever 12 and, therefore, the butterfly valve 10 located on the other arm 5 of the rotating lever 12 presses on the vent opening 8 and, thereby, close the vent valve 13. From now on, through an additional drag of the pull rod 11, keeping Hermetically sealed valve 13, body 1 of the discharge valve crawls up and, therefore, the Discharge valve valve plate 2 rises from the valve seat 3. Discharge water begins to discharge of the cistern. However, unlike the release of the large amount of discharge water, in case of a decrease in water level W in the tank due to valve 13 of closed ventilation, water cannot flow out of the water container 7. Therefore, the total vertical thrust of the body 1 of the discharge valve and plate 2 of the valve sits on the seat 3 of the valve before the total amount of water from discharge has left the tank. Ventilation valve 13, due to the suction of the water that is in the container 7 of water, remains closed until the water level W in the cistern again exceeds the level of water in the container 7 of Water. Then, in the water container 7 there is no longer any suction and the butterfly valve 10 rises again from the ventilation opening 8 after the pull rod 11, after releasing the knob, it has slid back into position at rest, that is, for example, due to the arm's own weight 9 opposite of the rotating lever 12, or also due to the action of a defined elastic force and, therefore, occupies the position of rest of the discharge valve 1, with the ventilation valve 13 open, necessary for a new optional release of a Small amount or large amount of discharge water.

In another embodiment of the invention especially advantageous, shown in figures 4, 5 and 6, in the Guiding part 15 for body 1 of the discharge valve is fixedly arranged an erect adjustment pin 16 towards up vertically, which can travel easily in a closed channel 17 arranged in the water container 7. In the resting position of the water discharge device, the adjusting pin 16 through the closed channel 17 arranged in the water container 7, protruding from the upper surface of the area of the wall of the water container 7 facing upwards, and lift arm 5 of lever 12 from the ventilation opening swivel equipped with butterfly valve 10. Also, with the bearing 19 of the rotating lever 12 is connected an element 20 of braking, which gives the bearing 19 a certain hardness and prevents the rotating lever 12 from moving due to the action of reduced random forces, for example, due to vibrations, etc.

In the case of the release of the quantity AG large discharge water, body 1 of the discharge valve, As shown in Figure 2, it is dragged up. Thus, the valve plate 2 is lifted from the valve seat 3. Simultaneously, due to the relative movement caused by the release between body 1 of the discharge valve and part 15 guided to the cistern, the adjustment pin 16 is removed from its upper position protruding through channel 17 closed in the water container 7. Through the action of element 20 of braking, the ventilation valve 13 is kept forward open safely, so that when the W level of the water (see figure 2), atmospheric air L can enter the water container 7 through the vent valve and, by this, water can leave the water container. Therefore, it increases the total vertical thrust of the discharge valve body of such so that the total amount of water contained in the tank before the discharge valve closes again. To the close the discharge valve, body 1 of the discharge valve returns to the rest position shown in figure 4 and, after filling the tank again, it is ready again for the optional release of the discharge of a certain greater or lesser amount of discharge water.

The release of the small amount of water from discharge in the case of this embodiment of the invention, in which the ventilation valve is controlled with interaction of the adjusting pin 16, is shown in figure 5.

By triggering the trigger for the small amount of discharge water, the pull rod 11 movably positioned on the water container 7. A traction flange 21 arranged in the pull rod 11 is attached from below to arm 9 of the lever of the lever 12 rotating transversely to the direction of traction, for example, by means of a drive pin 22 which protrudes laterally from arm 9 of the lever, and drags the lever arm 9 up. Therefore, not only creeps up the entire body 1 of the discharge valve, but also the rotating lever 12 rotates so that the arm 5 opposite of the lever with the butterfly valve 10 rotates down and close the ventilation opening 8. This is possible because at drag the body 1 of the discharge valve upwards performs a relative movement between the body 1 of the valve discharge and the guide piece 15 fixed in the cistern, and the spike 16 adjustment projecting vertically upwards from part 15 guiding is removed from its upper position protruding through of the channel 17 closed in the water container 7 and, with it, the lever arm 5 is no longer held in the raised position using the adjustment pin 16. The braking force exerted by the braking element 20 on the bearing 19, which prevents a rotation of the rotating lever 12 not loaded in the case of release of the large amount of discharge water by random forces, for example, vibrations, etc., is reduced by the much higher tensile force exerted from below by the pull rod 11 on the arm 9 of the lever 12 swivel, and arm 9 crawls up, whereby the arm 5 with the butterfly valve 10 is pressed on the opening 8 ventilation, and remains in this position also after the completion of the action of the tensile force AK by means of braking action of the braking element 20 and by the action of water suction in the water container 7. Through the water retained in the water container 7, the thrust Total vertical discharge valve body is reduced by one defined quantity and, therefore, after downloading an amount determined discharge water, before it has been discharged the entire amount of discharge water, the valve is closed again 2, 3 output. Upon reaching the closed position of valve 2, 3 of discharge, also the body of the discharge valve adopts from again its resting position, that is, the adjustment pin 16 erect perpendicularly upwards on the guide piece 15 crosses the closed channel 17 again in the water container 7 and protrudes from it, so that its tip presses the arm again 5 of the vent valve, in the raised position of the ventilation opening 8.

After a new tank load, the which is controlled in a known way by a special valve of supply, the water discharge device according to the invention is ready again for the optional release of a certain amount of water from the discharge through the independent command

Figure 6 illustrates in a partial view in perspective some details, not shown in the remaining figures, of the water discharge device according to the invention, thus, by example, that the adjustment pin 16 is not fixed directly to the lower part of the arm 5 of the lever lever 12 rotatable, but to the bottom of a connected drive flange 18 with the arm 5 of the lever and protruding laterally parallel to the lower part of the arm 5 of the lever, whereby it can renounce the tolerances of measures too narrow for interaction of the two pieces.

In addition, it can be seen that on rod 11 of traction is provided the protruding traction flange 21 transversely to the direction of traction, interacting this flange with the arm 9 of the lever lever 12 rotatable by means of the drive pin 22 protruding from the arm 9 of the lever transversely to the longitudinal axis of the lever 12 swivel

Finally, another form can be observed of possible embodiment of the braking element 20. Element 20 of braking is configured as an elastic element, for example, of elastic plastic, which presses radially on a configuration in the form of a circular segment of the rotating lever 12 by means of the bearing 19. By a braking element 20 of this type, increases the friction of the bearing in the bearing 19 and prevents the rotary lever, when not in operation temporarily by adjusting pin 16 or lever 22 of traction, is displaced by randomly acting forces, for example, by vibrations, etc.

The following advantageous embodiments of the invention are not shown in the figures: the container 7 of water forms, with the lever 12 rotating and the rod 11 of traction positioned displaceably on a bearing sliding arranged in the water container 7, as well as, given the case, with channel 17 closed, a construction group, which manufactures completely independent of valve body 1 discharge, and can be mechanically hooked with it by A simple lace connection. Therefore, it is possible, on the one hand, manufacture known standard bodies of the discharge valve (without water discharge of two quantities) and, on the other hand, to be able use these also for two water discharge devices quantities by simple mechanical coupling of the groups Additional constructs mentioned. This greatly reduces manufacturing, storage and sales costs.

In addition, it is advantageous to provide the bearing with sliding for the pull rod 11 or the rod 11 traction with one stop or with several stops, which limit the sliding movement of the pull rod 11 in the sliding bearing as necessary to drag the arm 9 of the rotating lever 12 upwards both that the butterfly valve 10 close the ventilation opening 8 of fixed way. By means of such a stop on the bearing of sliding and / or on the pull rod 11 prevents all the force necessary to lift the body 1 of the valve discharge act on the drive device on rod 11 of traction to lift the arm 9 of the rotary lever, as well as, on the bearing 13 of the rotating lever 12, and there cause a risk of breakage or increased wear.

The water discharge device according to the invention has the advantage that it has a simple structure and It is fundamentally less prone to breakdowns, compared to known water discharge devices with independent controls for the optional release of the discharge of a certain greater or lesser amount of discharge water.
