Description

The invention "relates to a toilet cistern with a Cistern housing, which holds a predetermined amount of water above a toilet bowl, a flush - ~ water control, which can be actuated in such a way that it releases V / water from the cistern for flushing, and a mechanical one Linkage for actuating the flushing water control.

In a toilet cistern that works like a siphon, water can drain up to a certain level rise, and flushing is carried out by actuating a siphon unit, whereby a volume of water is mechanically increased is used to set the siphon in motion, which empties the cistern to the toilet bowl.

Tests have shown that with a certain amount of water In a certain water column in the cistern the efficiency of the flush can be improved if one improves the piping system through which the water from Cistern is led to the toilet bowl. A useful improvement has been achieved by making a gradual Bending instead of a sudden bend in the connecting pipe was ensured. An enlargement of the pipe diameter has not proven to be particularly effective. Al-Lerdings it has now been established that another Improvement can be achieved by having a multiple line outlet and preferably a multiple Provides biphon system.

The invention is based on this discovery and is suitable for a toilet cistern with a drain valve as well as for a toilet cistern that works like a siphon.

The object of the invention is therefore to create an improved Lbortspülkasten.

The toilet cistern according to the invention is distinguished

assumes that the flushing water control has several water outlets

outlet lines, preferably two water outlet lines.

In a S; Lphonsystern the outlet lines can with be connected to a single siphon unit. Preferably, however, more than one siphon unit is provided, each has at least one outlet line. In the case of a drain valve arrangement, more than just a drain valve is used intended.

The outlet lines can be pipes which are connected to one another below the cistern before they enter the Lead the toilet bowl. Preferably, however, the lines enter the toilet bowl at the appropriate points a.

The invention is suitable for any type of abortion, be it simple, for example, with flushing down or double siphon-like closure or spiral-like closure.

The invention is described below with further advantageous details on the basis of schematically illustrated exemplary embodiments explained in more detail. In the drawings shows:

Fig. 1 is a perspective view of a siphon type drain with a cistern according to the invention;

FIG. 2 is a view similar to FIG. 1 of a toilet working with a drain valve with a cistern according to FIG Invention·

In Fig. 1, a toilet with a bowl 1 is shown, above which a cistern 2 is attached. The case of the cistern contains water up to a level indicated by the dashed line 3. The water inlet is by a ball valve not shown here in a conventional manner

Way closed. The cistern contains two siphon units 4 and 5, which are of conventional type and one below the other are the same. The siphon unit 4 has, for example, a bell 4a connected to an upwardly directed pipe 4b is. A downwardly directed pipe 4c is connected to the upwardly directed pipe via a U-shaped pipe bend 4d. Inside the bell there is a plate that normally rests on the floor. This plate comes with a connecting rod 4e, which is attached to a rod 6. It can be seen that the connecting rods of both Siphon units are connected to the rod 6.

To flush the cistern, there is one at the end of the rod 6 attached lever 7 operated to rotate the rod and thus raise the siphon plates. This raises water over the U-shaped arches and creates a siphon effect in each of the siphon units in progress.

The downwardly facing tubes 4c and 5c are connected to corresponding Outlet lines 8 and 9 connected, which lead to different parts of an outlet channel 10, which around the rim of the toilet bowl. Rinse water runs down from the outlet channel on the toilet bowl.

The efficiency of the flushing in the arrangement shown in the drawings can be used to reduce the to reduce the necessary water column in the cistern. This allows a very low cistern to provide what the Has the advantage of saving space and a pleasant aesthetic appearance. Conventionally, for example, the No less than 30 in. (76.20 cm) total height of a low flush toilet with a cistern. The one described here and In contrast, the arrangement shown in the drawing requires an overall height of 60.96 cm (24 inches) or less.

pig. 2 shows a toilet cistern with drain valve, in which the two siphon units 4, 5 according to Pig. 1

are replaced by drain valves H. These valves have Spunde 15, which sit in corresponding openings 16 of the outlet lines 8,9. On each drain valve 14 is a Float 17 attached, which gives the combination of float and valve a slight negative buoyancy. This Buoyancy is not enough to make the valve rise under normal circumstances, but it is not at the same time so negative that the valves could sink and close the mouths of the outlet channels until the flushing ended is when by lifting a button 7 a cLie Valves have been raised via ropes 4-e to flush the toilet.

The invention is not restricted to the arrangement explained in connection with the drawings. It can e.g. more than two siphon units or drain valves can be provided for simultaneous actuation.
