    The invention relates to a toilet system and a method for operating the toilet system. The toilet system can preferably be operated in mobile use and with vacuum support. The existing toilets can be so-called vacuum toilets.
    Manufacturers of toilet systems for mobile use, especially in rail vehicles, are faced in various applications with extreme situations with regard to the laying of the sewer line from toilet bowls to a waste water collector for the waste water. Long pipe routes, insufficient, sometimes no gradient or even an increase in a sewage pipe to the sewage collection tank and an undefined number of diversions make the requirements significantly more difficult. To make matters worse, for example when using the toilet systems in sleeping cars, a large number of toilets are connected via a few sewage pipes and at the same time there are few users. Despite these conditions, the manufacturers of the toilet systems must ensure a safe discharge over a long period of time. Blockages or deposits in the waste water pipes between the toilets and the waste water collection container should be avoided or simply removed.
    It is therefore an object of the invention to provide a toilet system that can be operated safely over longer periods of time without the need for complex maintenance work and blockages or deposits in sewage pipes between toilets and a waste water container can be avoided or easily removed, without manual intervention in the sewage system of the toilet system.
    According to the invention this object is achieved with a toilet system having the features of claim 1. The claim 6 relates to a method for operating the toilet system. Advantageous refinements and developments of the invention can be realized with the features specified in the dependent claims.
    For use under these conditions, a toilet system is proposed in which the conventional flushing process is supported by a time and / or usage-dependent compressed air and / or liquid bursts with increased pressure from a separate pressure vessel.
    The product of the pressure vessel internal volume and the relative pressure in the pressure vessel should be at least as large, preferably greater than the volume (standard liters) of all waste water lines via which the waste water collection container is to be discharged. In other words, this means that a gas, in particular air and / or a liquid, in particular water (preferably gray water), is / are contained in the pressure vessel with a volume which, under normal ambient pressure conditions (atmospheric pressure), is at least as large as the internal volume all waste water pipes between the toilets of the toilet system and the central waste water collector for these toilets. As is known, the volume of gases in particular increases when a pressure reduction occurs. This can be achieved by opening a first controllable valve on the pressure vessel. Accordingly, a smaller volume is required for a pressure vessel that can only be filled with compressed gas.
    The internal volume of the pressure vessel can also be larger than is necessary for triggering a single pressure surge and the cleaning of the sewage pipes that can be achieved thereby. After the first valve has been closed, at least one second valve, which is present on the pressure vessel, can be opened by means of the control in order to fill the pressure vessel sufficiently or completely. If a sufficient amount of gas and / or liquid with a sufficient pressure has been taken up inside the pressure vessel, the second valve can be closed.
    As already mentioned, the first and second valves on the pressure vessel can be operated by means of a controller. The first valve can be opened depending on a predeterminable number of uses of the toilets of the toilet system. The number of uses of individual toilets can be evaluated differently. For example, the number of uses of a toilet that is furthest away from the waste water collector or one that is located in an unfavorable sewer branch can be evaluated with a factor greater than "one" and other uses of toilets can only be taken into account individually if a predefinable number of uses for the control opening of the first valve is to be used.
    Alone or additionally, the opening of a first valve on the pressure vessel can also be triggered after a predefinable time interval or after reaching a destination in a rail vehicle. For example, pressure surges can be initiated at least once a day, after reaching a destination station or before each start-up after a long period of rest, in which the toilet system according to the invention was not in active use. Reaching a destination, commissioning are examples of events after which opening of a first valve can be triggered.
    An opening of a first valve can also take place if no or a reduced amount of waste water has been supplied to the waste water collection container within a predeterminable time interval, which can be an indicator of a deposit or a blockage in a waste water or the waste water collection line. For example, a level sensor in the wastewater collection container that is monitored over time can be used for this purpose.
    [0011] At least one sensor should be present in / on the pressure vessel, with which, for example, condition monitoring or regulation of the operation is possible. In particular, this can be a sensor for determining the internal pressure.
    A sensor should be connected to the controller for opening and closing the first and second valves. The filling of the pressure container and, if the pressure container is sufficiently large, the refilling up to a desired, predeterminable internal pressure can thus be influenced. If the pressure drops below a minimum, the at least one second valve can be opened in order to again reach a predeterminable minimum internal pressure.
    Additionally or alone, a temperature sensor can also be present on the pressure vessel, with which different temperatures during filling and in operation can also be taken into account.
    A first valve can be opened and closed by a central control in order to initiate a pressure surge in the sewage pipes and then close the valve again.
    A modified toilet control enables the effective use of the contents of the pressure vessel for all toilets integrated in a common sewage collection line. The pressure tank should be located near the toilet furthest away from the waste water collector and connected to the waste water pipe or close to the waste water pipe there. Differences in the running time of the pressure wave to more distant toilets can be compensated by an electronic control. The toilet system according to the invention has an improved energy efficiency compared to systems with a central vacuum, in which a relatively high negative pressure must be maintained in almost all waste water pipes between the individual toilets and the waste water collection container, since the pressure container can be operated, used or dimensioned accordingly .
    A further supply line with a further valve can be connected to the pressure vessel, via which gas or liquid can be supplied. A separate supply of gas and liquid into the pressure vessel can be realized in this way. For example, a liquid can be filled without pressure and a gas compressed into the pressure vessel until a predeterminable internal pressure has been reached.
    A pressure vessel can be filled or refilled via its own compressor assigned to it or via a central compressed air supply.
    There is also the possibility to connect the pressure vessel via several lines with sewage and / or the sewage manifold at different positions. In each case, a separately controllable first valve can be arranged in the lines, so that depending on the opening of a first valve, gas and / or liquid have a stronger flow through other areas of the waste water lines and / or waste water collecting line. This can also be controlled depending on the use after a predeterminable number of uses of the individual toilets has been reached.
    [0019] The invention will be explained in more detail below by way of example.
    [0020] Here:<tb> <SEP> Figure 1 is a block diagram of an example of a toilet system according to the invention.
    In the example shown in Figure 1, five vacuum toilets 2 are connected via waste water lines 5 and a waste water collecting line 4 to a waste water collecting container 3, into which the waste water from the toilets and possibly further process water are conducted and collected.
    In this example, the waste water manifold 4 is connected to a pressure vessel 1, which in turn is connected via line 6 to a compressed air system of a rail vehicle and can be closed with the second valve 1.2 when a sufficient internal pressure has been reached in the pressure vessel 1.
    As explained in the general part of the description, the first valve 1.1 can be opened when a predetermined number of uses of toilets has been reached or an event has occurred. The pressure vessel 1 can be completely emptied, so that the gas volume after the expansion corresponds at least to the inner volume of all waste water lines 5 and the waste water collecting line 4, whereby at least an almost complete flow through all line cross sections can be achieved, which in turn leads to the removal of deposits and blockages can be dissipated by the pressure surge in the waste water collecting tank 3.
