Abstract

The overflow tube (13) has fittings (19) above the water level (7) which when the cistern body (2) is overloaded, the air inlet into the overflow tube at the overflow opening is reduced. By forming of a closed flow in the lumen of the overflow tube, the outflow power is increased. The fittings consist of a cover which is fixed at a specific distance above the overflow opening and is plate-shaped. The cover extends over an upper edge of the overflow tube. Between the upper edge of the overflow tube and the cover is a ring-shaped gap. The distance between the cover and an upper edge of the overflow tube is approximately 6mm.

The invention 33 relates to a cistern with a reservoir and a lid, in which a drain garment is located, an inlet valve! and an overflow pipe with an overflow arranged above the water surface.

BACKGROUND OF THE INVENTION [0002] reservoir washers of this kind are generally known.

There are prapaaove pipes for drainage performance standards, which is generally the valve body of the drain valve. In such a standard, it is required that a maximum 15 mm back pressure be maintained at the inlet valve 0.23 1/330 inlet and after interruption. the water inlet has fallen to a minimum of 5 mm in 2 seconds. This standard has so far been fulfilled by the corresponding cross-sectional dimension of the overflow pipe, but in some cases large cross-sections such as 45 mm were necessary. The invention would like to remedy this.

SUMMARY OF THE INVENTION

The inventive tank flushing device is characterized in that the overflow pipe has means above the water surface which, when overfilling the reservoir body, reduces the access of air to the overflow pipe at the overflow opening and increases draining performance by creating a substantially closed flow in the overflow pipe cavity. the flushing cistern according to the invention, with an overflow pipe of internal diameter 23 mm, the above standard is guaranteed. The power output in this case is as big as it is already

karzK: The knob has a clearance of 45 mm. According to a further development of the invention, it is mounted on a yoke on which an overflow tube is also attached. According to an embodiment of the invention, the lid for the yoke is formed without the add-on piece.

Further advantageous features derive from the dependent claims, the following description and the drawing.

Prahl; An example of an embodiment of the invention will be explained in more detail in the following drawing.

1 is a schematic sectional view of an inventive tank flushing device. 1 is a partial view of FIG. 1; FIG. 3 is a partial view of FIG. f design yields a reservoir flushing a

Figure 1 shows a reservoir flushing device having a cuboid body of a reservoir body 2, which is, for example, mounted on a toilet bowl (not shown). A removable lid 3 is provided on the body of the reservoir 2, in which the reservoir control button 17 is mounted. 2, an inlet valve of a known type is provided, which is provided with a mine-inlet tube S and a float 5. Usually as a "float valve" the indicated inlet valve 4 opens and closes depending on the water level 1.

The bottom 5 of the container body 2 is provided with a drain outlet 10 which forms a drain valve 12 together with the generally known drain garment 11. The valve 12 is opened by pulling out the central tube 13 which simultaneously forms the overflow tube. a button 17 on which the arm 1 (5, which engages in the yoke 15) is arranged. This yoke 15 has the shape of a fork according to FIG. 2 and is fixed at the upper end of the tube 13. Ί

The flush tank 1 shown in Figure 1 is stretched S1 and ready for flushing. The water level 7 is somewhat below the overflow opening 13 of the pipe 13. The lid 19 is arranged on the yoke 15 and is preferably mounted on the yoke 15. The horizontal lid 12 is located in a certain direction. This distance C is, for example, mm. As shown in particular in FIG. 3, the edge 20 of the lid 1 extends the edge 22 of the pipe 13. Thus, an annular gap 23 is formed between the edge 22 and the lid 13. The lid 19 is preferably closed, but this is not a condition. The lid may also be replaced by another element. It is essential that it partially obscures the opening 18 and fulfills a function which will be explained in the following.

For example, in Figure 2, the flushing cistern is overfilled due to a defect in the inlet valve 4. At a constant inflow of 0.23 l / seo, the height of the backwater A at 15 mm is stabilized. The cap 13 reduces the air inlet into the cavity 21 so that it is 21 against the tube 19. The diameter D can be 15 m above the A and the backflow A of the tube. Thus, at a given drainage power, the tube D can be kept at a maximum of 15 mm A at a given drainage power than at the container in the example of said inflow. If the flushing water inflows into the cistern 1, the backflow height A decreases and the water level J finally drops to the pipe edge 22. Due to the increased outflow of the pipe 13_, the backwater height Λ of Figure 4 decreases after the inflow in time of 2 seconds to a height of 5 mm.

Since, unlike a conventional flushing cistern, only a comparatively simple accessory piece 14 is required, which can be made of plastic, the additional manufacturing cost has almost no weight. However, the cap 19 can also be welded to the yoke 15_.
