The publications mentioned are not suitable for deriving a toilet hygiene system with practical requirements. The major pioneering inventions have so far not been used in toilet applications, although highly innovative inventions have found their way into all areas of the human environment.

 Solution

The additional device is screwed onto the existing holes in the toilet bowl. The 3-way valve VI is activated by the trigger mechanism (foot, hand or combined) and the working fluid pressure (e.g. water) acts on the cylinder (ZA) which is in tandem with the cylinder (ZB) via the common piston rod. The cylinder (ZB) is several times larger in cross section than the cylinder (ZA). This is drawn from the starting point to the end point and there is overpressure on the piston cable side of the cylinder (ZB) and negative pressure on the piston rear side. The negative pressure is piped through the toilet seat axis (4a) to the suction pads (4b)) in the toilet seat ring (4). The overpressure side is connected via pipes to the pneumatic pressure bellows (8a), which has the result that, at the same time as the negative pressure is generated, the resulting excess pressure is piped to the pressure bellows (8a) around the WC locked in the reservoir (3) on locating pins (8) -Press paper pads against the suction nubs (4b) to prevent gaps from forming so that the vacuum can be built up quickly. The diaphragm valve (V2) responds to this negative pressure and directs the working fluid pressure to the cylinder (Z1), which is advantageously positioned transversely to the toilet seat axis by means of a chain, a toothed belt and a pulley that wraps around the pinion shaft of the toilet seat axis (4a) and simultaneously the return energy

saves. This energy can be: a spring, gas spring or working fluid pressure (e.g. Vasser pressure). The cylinder (Z1) moves the toilet seat onto the toilet bowl with adherent paper support. The toilet operator lets the automatically running system stop as long as the usage time is. After relieving the pressure on the toilet seat, the stored energy pulls this seat back. That from the

Cylinder (ZA) + (Z1) pressed work equipment is directed into the water box or toilet bowl via the 3-way valves (V1) + (V2). The return movement of the cylinder (ZB) changes from the negative pressure. For generating overpressure, whereby the suction nubs (4b) are ventilated and the overlay paper is ventilated, which supports the paper rinsing. The return water from (Z1) is reduced to one

pneumatic bellows (9), which triggers the flushing mechanism with its expansion. In order to easily recognize the paper supply, there is a display slide (7a) whose symbol is in the oval pivoting middle part (6). -or number marking through a plexiglass window (7) can be seen from a greater distance. The amount is determined by measuring the thickness of the stock

 Tactile lever (7b) which moves the respective deflection

Tooth segment, ratio pinion 1:10, transmitted to the indicator slider via positive pinion transmission. When the seat is lowered, several locking segments are pivoted eccentrically from the oval center piece against the end frame (3a) via the toilet seat axis (4a) on which an eccentric piece on the 4-arm driving lever (6b) positively swings and thus closes the reservoir against external influences. The vacuum system allows automatic monitoring in the vise, so that the function is only ensured if paper is stored, the flushing trigger is intact, the pipe system is tight and there is sufficient system-determining energy, ie work equipment.
