Definitions

the invention relates to a flushing device for a toilet cistern, with separate controls for optionally triggering the flow of a certain larger or smaller amount of flushing water.
flushing devices which are also referred to as dual-flush devices, are e.g. B. from the European patent application EP 0 723 050 A1, the German utility model DE 295 17 393 U1 and the patent application PCT / EP91 / 01374 known.
a two-quantity flushing device which uses a drain valve common in toilet cisterns, in which a valve disc is lifted from a valve seat located at the outlet in the bottom of the cistern by lifting the drain valve body and kept lifted for at least one float by the buoyancy effect until the cistern is completely emptied.
two floats are provided, one of which is fixed and the other detachably connected to the drain valve body. When triggered the large amount of flushing water, both floats are connected to the drain valve body.
German utility model DE 295 17 393 U1 when the small amount of flushing water is triggered, the buoyancy of the drain valve body is reduced and the drain valve is closed again after a certain amount of partial flushing water has expired. This is done by an additional weight body with which the drain valve body is locked via a swivel lever gear when the small amount of flushing water is triggered. The additional weight body counteracts the buoyancy of the float and presses the valve plate back onto the valve seat of the drain valve before the total amount of flushing water contained in the cistern runs out.
the different buoyancy of the drain valve body when a larger or a smaller amount of flushing water is triggered is controlled by a loading bell that is firmly connected to the drain valve body and can be filled with water, which bell, depending on whether the flushing process is triggered and After lifting the valve plate from the valve seat, air can enter the load bell from the outside or not, the drain valve body either remains heavy due to the water filling of the load bell and thereby the drain valve closes prematurely, or the buoyancy increases due to the penetration of air, and thereby the drain valve is kept open until all of the flushing water in the cistern has run out.
the air is supplied to the bell via a flexible, coiled hose that goes from the inside of the load bell to the outside of the Cistern leads.
a ventilation valve combined with the trigger button for lifting the drain valve. This is always open in the rest position.
the bell can always run full of water when filling the cistern because any air in the bell can be displaced to the outside through the hose.
a rocker arm is pressed in one direction in this flushing device, whereby only the drain valve body is raised, but the ventilation valve remains open.
the invention is therefore based on the object of providing a flushing device for a toilet cistern with separate control elements for triggering the outflow of a certain larger or smaller amount of flushing water, which is uncomplicated in structure and less susceptible to faults.
a valve plate 2 of a drain valve body 1 rests on a valve seat 3 and prevents the rinsing water 4 from escaping from a cistern (not shown).
An essentially annular, downwardly open water vessel 7 is fixedly arranged around the upper region of the drain valve body 1.
a ventilation valve 13 which is always open in the rest position in the upwardly facing wall region of the water vessel 7 and comprises a ventilation opening 8 and a pivoting lever 12 with a valve flap 10 arranged thereon, any air in the water vessel 7 is pushed out through the ventilation opening 8 when the cistern is filled, so that the water vessel 7 is completely filled with water in the rest position.
the water container 7 is again completely filled with water even when it is refilled due to the ventilation valve 13 which is always open in the rest position and through which all air L in the water container is displaced.
the corresponding control element pulls the pulling rod 11 arranged laterally and parallel to the drain valve body 1 for the smaller flushing water amount.
This pull rod 11 is in the drain valve body 1 or in the water vessel 7, parallel to Axis of the drain valve body 1 is slidably mounted in such a way that it first moves upward relative to the drain valve body without pulling the drain valve body 1 and thereby, for. B.
the ventilation valve 13 remains closed due to the suction of the water in the water vessel 7 until until the water level W in the cistern again exceeds the water level in the water container 7. Then there is no more suction in the water vessel 7 and the valve flap 10 lifts after the pull rod 11 has slid back into its rest position after releasing the control element, e.g. B.
a fixed upright adjusting pin 16 which in a closed channel 17 arranged in the water vessel 7 with clearance fit is movable.
the actuating pin 16 protrudes through the closed channel 17 arranged in the water vessel 7, beyond the upper surface of the upwardly facing wall region of the water vessel 7, and lifts the arm 5 of the pivoting lever 12 provided with the valve flap 10 from the ventilation opening .
a brake element 20 is connected to the bearing 19 of the pivot lever 12, which gives the bearing 19 a certain stiffness and prevents the pivot lever 12 from accidental small forces, z. B. can be adjusted by vibrations, etc.
the drain valve body 1 When the large flushing water quantity AG is triggered, the drain valve body 1 is pulled upward, as shown in FIG. As a result, the valve plate 2 lifts off the valve seat 3. At the same time, as a result of the relative movement caused by the release between the drain valve body 1 and the guide part 15 anchored in the cistern, the actuating pin 16 withdraws from its uppermost position which projects through the closed channel 17 in the water vessel 7. Due to the action of the braking element 20, the ventilation valve 13 is still securely kept open, so that when the water level W (see FIG. 2) drops, the atmospheric air L can flow into the water vessel 7 through the ventilation valve and the water can thereby escape from the water vessel.
FIG. 5 The triggering of the small amount of flushing water in this embodiment of the invention, in which the ventilation valve is controlled with the assistance of the actuating pin 16, is shown in FIG. 5.
the pull rod 11 By actuating the trigger for the small amount of flushing water, the pull rod 11, which is displaceably mounted in the water vessel 7, is pulled upward.
the pivot lever 12 is pivoted in such a way that the opposite lever arm 5 pivots with the valve flap 10 downward and closes the ventilation opening 8.
the drain valve 2, 3 also the drain valve body returns to its rest position, ie the control pin 16 standing vertically upwards on the guide part 15 penetrates again the closed channel 17 in the water vessel 7 and protrudes therefrom, so that its tip arm 5 of the ventilation valve presses again into the position lifted from the ventilation opening 8.
the flushing device according to the invention After refilling the cistern, which is controlled in a known manner by a special inlet valve, the flushing device according to the invention is again ready to selectively trigger a certain larger or smaller amount of flushing water by means of the separate operating elements.
Figure 6 illustrates in a partial perspective view some details of the flushing device according to the invention, not shown in the remaining figures, such. B. that the actuating pin 16 does not act directly on the underside of the lever arm 5 of the pivoting lever 12, but on the underside of an actuating flange 18 connected laterally to the underside of the lever arm 5 and parallel to the underside of the lever arm 5, which results in excessively narrow dimensional tolerances for the interaction both parts can be dispensed with.
the pull flange 21 projecting transversely to the pulling direction is arranged on the pull rod 11 and cooperates with the lever arm 9 of the pivot lever 12 via the actuating pin 22 projecting from the lever arm 9 transversely to the longitudinal axis of the pivot lever 12.
the braking element 20 is as a resilient element, for. B. made of elastic plastic that presses radially on a circular segment-shaped design of the pivot lever 12 above the bearing 19.
the braking element 20 By such a braking element 20, the bearing friction in the bearing 19 is increased, and it is prevented that the pivot lever, if it is temporarily not operated by the actuating pin 16 or the pull lever 11 in operation, by randomly acting forces, e.g. B. adjusted by vibrations, etc.
the water vessel 7 forms a subassembly with the pivot lever 12 and the pull rod 11, which is displaceably mounted in a slide bearing arranged on the water vessel 7, and optionally with the closed channel 17, which is manufactured completely separately from the drain valve body 1 and can be locked with it by a simple snap-in connection.
the slide bearing for the pull rod 11 or the pull rod 11 itself with a stop or a plurality of stops, which limit the sliding movement of the pull rod 11 in the slide bearing to the extent required by the arm 9 of the pivot lever 12 as far as possible to pull up that the valve flap 10 closes the ventilation opening 8 firmly.
a stop in the slide bearing and / or on the pull rod 11 it is avoided that the entire force required for lifting the drain valve body 1 acts on the driver device on the pull rod 11 for lifting the pivot lever arm 9 and on the bearing 13 of the pivot lever 12 and there one Risk of breakage or increased wear.
the flushing device according to the invention has the advantage that it has a simple structure and is much less susceptible to faults in comparison to the known flushing devices with separate operating elements for optionally triggering the flow of a certain larger or smaller amount of flushing water.
