Abstract

In the application, a system for functionally extending conventional WC cisterns with float-controlled sealing bell for closing the outlet pipe is described. The possibility is to be provided of discharging at least two different-sized quantities of water by means of an additional device. This is achieved in that an additional float (2), freely movable around the sealing bell (1), is provided with a buoyancy body (3) and an additional weight (4) and is held in the rest position by a magnet (6) fastened to the WC cistern (5). By means of an actuating element (7) to be controlled from outside, the steel disc (8) integrated in the additional float (2) is separated from the magnet (6), so that when the water level falls the additional float (2) with its resulting weight is laid upon the sealing bell (1) and leads to early closure of the discharge pipe, as a result of which some of the water remains in the WC cistern. The described functioning of the system according to the invention can be seen in the enclosed drawing (Figure 1). <IMAGE>

Description

System for expanding the functionality of conventional toilet cisterns.

The invention relates to a system for expanding conventional functions Toilet cisterns with float-controlled sealing bell to close the drain pipe.

With such toilet cisterns, the possibility should be created dispense at least 2 different amounts of water through an additional device.

Cisterns are known, especially for toilet systems (see PS 9 63 319) where it is possible to add any desired amount of water by raising it the bell from the cistern. So the total amount of water of the Cistern made to flow out by lifting the bell for a long time. With more or less short actuation of the pulling device is the one flowing out of the cistern Infinitely variable amount of water.

The prerequisite for dispensing the desired amount of water is here however, the exact adherence to the respectively desired Amount of water assigned duration of operation. A determination of different amounts of water that can be called up can not.

There are also known toilet flushing devices in which the upper The interior of the flushing block can be filled with air through an air inlet valve, so that the reber effect and thus the flushing process at any point in time is interrupted. However, these known flushing devices have not caught on, because they are too expensive to buy and complicated to set up and therefore very prone to failure are.

In the DOS 26 29 162 a device for limiting the water outflow Described from water tanks in which different amounts of water can be called up are. This object is achieved in that the actuating means from FIG. 2 is telescopic parts that can be pushed into one another, one facing away from the other The end is pivotally connected to the rod carrying the plate and the other movable part on the side of the pivot point facing the rod Carrying weight.

The actuating means is now designed in such a way that when it is fully extended, the weight-bearing part of the container empties completely before the rubber plate again closes the outlet pipe. If not all of the contents of the Toilet cistern is required, the weight must not be pulled out will. Here, too, additional handling is assumed by the user, which the Prevented the implementation of this system on the market.

The filling of the conventional cisterns that have been used up to now is in set approximately between 6 and 10 1. When in use, the entire amount of rinse water discharged through the drainpipe, resulting in a significant waste of fresh water contributes. These disadvantages are particularly noticeable in large cities and metropolitan areas, as the increasing environmental pollution and the increasing representation end Fresh water scarcity the surface water is treated at high cost have to.

The invention is therefore based on the object of conventional toilet cisterns that are too round with float-controlled sealing bell for closing the drainpipe with an additional system to provide, which the flushing system so in its function with the least effort extended that rinsing with a metered amount of the rinsing water at the request of the User without additional handling and settings is possible.

This object is achieved according to the invention in that a the Sealing bell (1) freely movable additional bedroom (2) with a float (3) and an additional weight (4) and in the rest position of one on the toilet locker (5) attached magnet (6) is held. By an actuating element that can be controlled from the outside (7) the steel disc (8) integrated into the additional float (2) is removed from the magnet (6) separated, so that the additional float (2) with falling water level with his resulting weight on the sealing bell (1) and premature closure the drain pipe leads, whereby some of the water remains in the toilet cistern.

The measure according to the invention ensures that the valve the outlet pipe only remains open until the flush volume specified by the design left the toilet cistern.

When testing the system, it has proven to be advantageous Set the holding force of the magnet (6) to be greater than the resulting weight the additional float (2).

In a variation of the inventive concept that is not described in more detail is, the magnetic attachment (6) of the additional float (2) by a form-fitting Bracket by means of two Soheren levers are replaced.

To be aware of the different dimensions of different types of toilet cisterns to be able to adapt, in a variant according to the invention, the upper part (11) of the additional float (2) is provided with a height adjustment option (perforated Side panels) which enables the adjustment.

It has been found to be advantageous to use the float (3) of the additional float (2) Manufactured from closed-cell foams such as Styrofoam or PUR.

The actuating elements (7, 12) get a bias, which produced according to the invention by helical springs (9) or also by foam can be.

It is advantageous for the function of the system according to the invention also that when the toilet cistern is full, the immersion depth of the additional float (2) is dimensioned so that the buoyancy of the float (3) the additional float (2) presses against the magnet (6).

An embodiment of the invention is shown in the drawing and is described in more detail below. They show: FIG. 1: Section through the front view.

Figure 2: Positive mounting of the additional float by means of two Scissor lever.

Figure 3: Variant of the additional float with the possibility of height adjustment.

In Figure 1, the starting position of the system when the cistern is full shown. The sealing bell (1) has the outlet hope (not shown in the drawing ) closed. The additional float (2) has risen due to the incoming water and became in the area of attraction of the magnet when the final water level was reached (6) recorded and held by this.

To ensure that the additional float (2) from Magnet (6) is detected, its immersion depth when the toilet cistern was full dimensioned so that it is additionally affected by the water pressure - after reaching the eniviasserstandes - is pressed against the magnet.

If the full amount of water is now required, all that is needed is the actuating element (12) to press. The sealing bell (1) is raised via the lever (14), so that the water begins to run out. Since the sealing bell (1) with a (not shown) Is provided with a float, the buoyancy of the sealing bell (1) is above the closing pressure, so that the toilet cistern runs completely empty.

If the set small amount of water (e.g. 4.5 l) is required, so both actuating elements (7, 12) must now be pressed. The sealing bell (1) is raised by the actuating element (12), while the additional float (2) by the push button (13) is separated from the magnet (6). The additional float (2) sets now when the water level falls rapidly due to its resulting weight the sealing bell (1), which remains in the open state for the time being. The lift At this point in time, your float is even greater than the weight of the sealing bell (1) and additional float (2). After about half the amount of water has expired the weight of the sealing bell (1) and the additional float (2) is greater than the buoyancy. The sealing bell sinks and closes the outlet opening with its rubber plate of the cistern. The additional float is now due to the water flowing in again (2) raised and pressed against the magnet (6) after the final water level has been reached and held by this. A new rinsing process can begin.

As shown symbolically in FIG. 2, the additional swimmer can (2) with the same function as described in Figure 1, instead of a magnet (6) as well held by 2 scissor levers (10). Instead of the one integrated in the additional sockwimmer Steel washer (8) is the upper end of the additional float with groove-like undercuts provided, which allow the scissor lever to reach around.

The additional float is triggered as described in Figure 1 over the actuating element (7) and the finger (13), which over the helical spring (9) is held in the starting position. To adapt to structurally specified Dimensional differences in the various toilet cisterns can occur with an inventive Variant of the additional float (2) in its webs (11) are designed so that the respective adaptation to the Achieving the desired amount of rinse water is made possible.

The advantages of the described system according to the invention for expanding functions conventional W0 cisterns can be seen in the fact that the adaptation to the various given toilet cisterns is possible without structural changes and the delivery different amounts of water to adapt to the respective If necessary, by simply pressing two elements (7, 12) is made possible without that a different holding or volume-adapted adjustment is required.
