Drain valve for toilet cisterns

The object of the innovation is a swim-controlled drain valve for toilet cisterns for draining a _2Ö selectable amount of water via a drain pipe into the toilet bowl.

Drinking water is generally used to flush a toilet bowl, about 9 liters each ] 25 Rinsing process. Because of the increased environmental awareness in large parts of the population the knowledge has enforced that drinking water is not available indefinitely, and for its extraction more and more complex procedures have to be used 3Q, there was no lack of suggestions,

Reduce the amount of water used to flush the toilet. It is known that only for a minor

Part of all flushing processes the full amount of water is required, be it for cleaning reasons or for a Blockage in the only slightly sloping underground Avoid sewer pipes and sewers. There were therefore cisterns of various types constructed that are able to handle different amounts of water to dispense one or more valves in the toilet bowl.

Toilet boxes with several outlet valves (DE-OS

can be operated with each other are because of the |

safe. It was therefore in DE-OS 30 36 590 a | float-controlled valve proposed in which two on levers at different heights Swimmers hold the operated valve by means of a detent lock until the water level rises the desired height has fallen and the lock connected to the float is released, so that the Valve body can close the valve opening. Those sensitive to dirt and deposits However, detent locks impair the functionality of these outlet valves.

It was therefore the task of a float-controlled

Drain valve for toilet cisterns / for draining a,

to develop a selectable amount of water that does not periodically lie under water against pollution sensitive parts such as joints and detent locks having.

The object is achieved according to the invention by an outlet valve which, in a manner known per se, consists of a hollow valve body (1) with a sealing washer (2) and a valve body (1) located in a float housing (3) with an outlet opening (4) and loosely enclosing the valve body (1) The float (5) consists and is provided with at least one float (6) arranged above it and displaceable on the valve body (1), the float (5) and float (6) each being provided with a hold-down device (7 * 8), which is above the water level is held by a releasable lock from the outside (9, 10) and the valve body (1) on the outside above the float (5) and the buoyancy body (6) with projections (11, 12) provided ^1St ·

The locks are preferably suspended movably in the upper part of the cistern above their center of gravity and return to their upright position,

as soon as the swimmer or the float after the 20th

Drained the water taken their lower position

to have.

The restoring torque must be large enough to reduce the bearing friction to overcome and return the controls (13, 14) to their original position. The controls are designed so that with one only the lock of the float, but with the other both locks can be released. Floats and floats can be made of closed-cell plastic foam exist or be designed as a hollow body or as a bell open at the bottom.

Push rods as operating elements.

Fig. 2 shows levers as operating elements with the associated locks.

The outlet valve remains closed due to the water pressure acting on the sealing washer (2). By pressing the push rod (14), the lock (9) is pivoted to the left and the hold-down device (8) of the ■ The float (6) is unlocked. The float (6) floats up and engages under the projection (12) of the valve body (1) and lifts it. The outlet valve remains open until about 3 liters of water have flowed out and the float (6) has returned to its starting position. Of the Hold-down device (8) clears the way for the lock (9), which, due to its own weight, is in the vertical position : Position swiveled back while the push rod (14)

thereby swiveled to the left and the hold-down devices (7, 8) of the float (6) and the float (5) are unlocked. The float (6) pulls the valve body (1) and thus opens the drain valve. After the expiration of more than 3 liters of water, the valve body (1) is removed from the float (5) solely via its projection (11) kept open. The outlet opening (4) in the float housing (3) is selected as usual so that the float is buoyant (5) large enough to lift the valve body (1) until the entire amount of water is out of the cistern has flowed out. The float (6) is supported so that the float (5) that is too large does not have to be used. advantageously not on the hold-down device (7), but on the ring segment (15) of the float housing (3).

The actuation mechanism can also be implemented in other ways, for example, as shown in Fig. shown. The lock (10) can be swiveled in the upper part of the cistern between two bars (20) stored, of which at least one is provided with a guide groove (21) in which the pin (22) the lock (10) moves. The axis of the center of gravity of the lock (10) does not go in the rest position through the pivot point, so that a moment remains that pushes the pin (22) against the end of the guide groove (21) presses. This protects the lock (10) against unintentional unlocking. The levers (16, 17) are also mounted between two webs (18) of the upper cistern part and articulated with the locks tied together. With the lever (17) the lock for the hold-down device of the float is actuated to the to allow less water to flow out.

It lies below and in front of the lever (16) with an L-shaped extension (19) which rests on the lever (17). When the lever (16) is depressed, the lever (17) is also actuated, so that the entire amount of water flows out.

The lock and bearings that belong to the lever (17) are not shown for reasons of clarity, but correspond to those of the lever (16).
