Abstract

A flush water container system for the flush water of a mobile toilet (11), in particular of a mobile vacuum toilet (11), comprising

• • a flush water container (43) having a flush water container inflow (44),
  • characterized in that the flush water container (43) is designed to receive gray water from a washbasin (10), which in particular is a wash hand basin or a shower washbasin, and
  • a metering device (41) is provided, which is in fluidic communication with the flush water container (43) and is designed to treat the gray water by feeding a descaling and/or bactericidal treatment agent,
    wherein the flush water container (43) is designed to release the treated gray water as flush water to the mobile toilet (11).

Claims

1. A flush water container system for flush water for a mobile toilet, in particular of a mobile vacuum toilet, comprising

a flush water container having a flush water container inflow,

characterized in that the flush water container is designed to receive gray water from a washbasin, which in particular is a wash hand basin or a shower washbasin, and in that

a metering device is provided, which is in fluidic communication with the flush water container and is designed to treat the gray water by feeding a descaling and/or bactericidal treatment agent,

wherein the flush water container is designed to release the treated gray water as flush water to the mobile toilet.

2. The flush water container system according to claim 1, wherein the metering device is in fluidic communication with the flush water container inflow in order to feed the treatment agent into a feed pipe connected to the flush water container inflow.

3. The flush water container system according to claim 1, wherein the metering device in fluidic communication with the flush water container in order to feed the treatment agent into the flush water container.

4. The flush water container system according to claim 1, wherein the metering device is designed to add the descaling and/or bactericidal agent to the gray water regularly, in particular continuously and/or at specified time intervals.

5. The flush water container system according to claim 1, wherein the flush water container system further comprises a sensor for detecting an event and/or a filling level of the flush water container, and a control unit for controlling the metering device, and wherein the control unit is in signal communication with the sensor and is so designed that, in response to the detected event and/or filling level, it causes the metering device to add the descaling and/or bactericidal agent to the gray water.

6. The flush water container system according to claim 1, wherein the flush water container system further comprises a filter for filtering the gray water, in particular for filtering particles out of the gray water, wherein the filter is arranged, in particular, in the flush water container inflow.

7. The flush water container system according to claim 6, wherein the filter has a filter fabric which in particular is bactericidal and/or contains silver threads.

8. The flush water container system according to claim 1, wherein the flush water container system further comprises an odor trap, which in particular is a valve or a siphon, arranged in the flush water container inflow.

9. The flush water container system according to claim 1, wherein the flush water container system has a minimum level sensor for detecting a filling level of the flush water container for flushing the mobile toilet and a control unit for controlling at least one valve that controls the inflow to the flush water container, and the control unit is designed to cause the flush water container to receive fresh water from a fresh water supply When the detected filling level is below a predetermined threshold value.

10. The flush water container system according to claim 1,

characterized by a treatment agent connector preferably provided in the form of a bayonet-type connector on the metering device for connecting to a reservoir, and a reservoir for the treatment agent, said reservoir being provided in the form of a bag and having a matching discharge opening for connecting to the treatment agent connector.

11. The flush water container system according to claim 1,

characterized by a metering piston, which is in fluidic communication with the flush water stream on a first side and in fluidic communication on its opposite side with the reservoir and which is preferably biased by a spring in a direction against the compressive force acting on the first side, wherein the metering piston defines on its second side a metering chamber which is in fluidic communication with the flush water container via a fluid conduit.

12. The flush water container system according to claim 1,

characterized in that the metering device is arranged on a filtration device, in particular on a filtration device comprising a filter element, which is inserted into a connection line between the washbasin and the flush water container, and a collecting tank, which is designed to receive solids filtered out by the filtration device, in particular by the filtration device further comprising a flushing device which has a flushing inflow and a flushing outflow and is designed to flush solids collected in the region of the filter element into the collecting tank, wherein the flushing inflow is preferably designed and arranged with a double function as an inflow for adding a descaling and/or bactericidal treatment agent to the metering device.

13. A flush water system of a mobile toilet, in particular of a mobile vacuum toilet, comprising

a flush water container system according to claim 1, and

the mobile toilet, in particular the mobile vacuum toilet.

14. The flush water system according to claim. 1, wherein the flush water system further comprises the washbasin.

15. A method for operating a flush water system of a mobile toilet, in particular of a mobile vacuum toilet, comprising a flush water container system according to claim 1, and the mobile toilet, in particular the mobile vacuum toilet, wherein the flush water system further comprises the washbasin, in particular, and the method further comprises the steps of the method for operating a flush water container system according to the invention for a mobile toilet, in particular for a mobile vacuum toilet.
