Definitions
- the present invention relates to a vacuum toilet which has a toilet bowl, a transfer tank and a flushing water tank.
- the flushing water tank is designed and connected in such a way that when the toilet is actuated, a flushing process is triggered, in which, with the help of an overpressure applied in the flushing water tank by a compressed air source, flushing water is conveyed from this via a first flushing water line into the toilet bowl.
- the transfer tank is designed and connected in such a way that, after the flushing process, suction compound is sucked out of the toilet bowl using a negative pressure applied to the transfer tank.
- Vacuum toilets are used, for example, as toilets in vehicles (e.g. rail vehicles, airplanes, water vehicles, buses, etc.) and offer the possibility of sucking suction mass out of the toilet bowl into a transfer tank with the help of a vacuum and then finally passing it on to a waste water reservoir .
- vehicles e.g. rail vehicles, airplanes, water vehicles, buses, etc.
- Such a vacuum toilet is known, for example, from DE 20 202 101 760 U1.
- the vacuum toilet includes a toilet bowl, a transfer tank, and a flush tank.
- the flushing water tank is designed and connected in such a way that when the toilet is actuated, a flushing process is triggered, in which, with the help of an overpressure applied in the flushing water tank by a compressed air source, flushing water is conveyed from this via a first flushing water line into the toilet bowl.
- the transfer tank is designed and connected in such a way that, following the flushing process, suction mass is sucked out of the toilet bowl into the transfer tank using a negative pressure applied to the transfer tank. In such a vacuum toilet, impurities can accumulate in the accumulate in the transfer tank, which eventually even lead to a blockage of the vacuum toilet.
- this second flushing water line fed by the first flushing water line.
- This second rinsing water line has a controllable valve that can release or block the rinsing water flow in the second rinsing water line.
- suction mass is understood to mean the mass that is removed from the toilet bowl when it is flushed.
- the suction mass can contain flushing water as well as faeces and other components.
- the second flushing water line preferably branches off from the first flushing water line via a connection in the form of a T-piece.
- the flushing water flows from the first flushing water line z. B. into the vertical branch of the T-piece shape and divides into two flushing water streams in the T-piece shape, by one flushing water stream, which continues to form the flushing water stream of the first flushing water line, e.g. B. through the left horizontal branch, and the second rinse water stream, which is the rinse water stream of the second flushing water line flows out through the right horizontal branch of the tee shape.
- the transfer tank preferably has a rinsing nozzle with a plurality of nozzle openings that is fed by the second rinsing line.
- This rinsing nozzle device in the transfer tank ensures that as many as possible and ideally all areas of the inner wall of the transfer tank are rinsed.
- the first flushing water line is also provided with a controllable valve.
- the two controllable valves on the flushing water lines can be controlled independently of one another. This allows the flow of flushing water to be routed in different ways. If the valve of the first flush water line is open and the valve of the second flush water line is closed, flush water can flow from the flush water tank into the toilet bowl but not into the transfer tank. If the valve of the first flush water line is closed and the valve of the second flush water line is open, flush water can flow into the transfer tank but not into the toilet bowl. If both valves are open, flushing water can flow into the transfer tank and into the toilet bowl.
- controllable valve of the second flushing water line is designed as a 3/2-way valve.
- controllable valves are preferably solenoid valves. Further preferred embodiments relate to an electronic control device that the vacuum toilet has. This control device is programmed to control the compressed air source and the controllable valve of the second flushing water line in such a way that the transfer tank is flushed under predefined conditions.
- control device is set up to check the number of flushing processes of the toilet bowl after the last flushing of the transfer tank as a predefined condition. After a predetermined number of flushing processes, the control device controls the compressed air source and the controllable valve on the second flushing water line in such a way that a separate flushing process is carried out for the transfer tank.
- control device is set up to check the number of flushing processes of the toilet bowl after the last flushing of the transfer tank as a predetermined condition. After a predetermined number of flushing processes, the control device controls the compressed air source and the controllable valve on the second flushing water line in such a way that the transfer tank is flushed at the same time as the next flushing process of the toilet bowl.
- control device is set up to check the elapse of a predetermined regular time interval as a predetermined condition. After this time interval has elapsed, the control device controls the compressed air source and the controllable valve of the second flushing water line in such a way that the transfer tank is flushed.
- control device is set up to check, as a predefined condition, whether there is a frost emptying signal for the vehicle. The frost emptying signal is triggered before the train closes, for example, in order to empty all water-carrying pipes and containers.
- control device controls the compressed air source and the controllable valve of the second flushing water line in such a way that the flushing water that is drained is used to flush the transfer tank. This ensures that the transfer tank is cleaned before the vacuum toilet is not used for a longer period of time in order to prevent deposits from solidifying in the transfer tank.
- Figure 1 shows a schematic structure of the vacuum toilet with a controllable valve on the second flushing water line
- FIG. 2 shows a schematic structure of the vacuum toilet with a controllable valve on the second flushing water line and a controllable valve on the first flushing water line,
- Figure 3 shows a schematic structure of the vacuum toilet with a controllable valve on the second flushing water line, which is designed as a 3/2-way valve.
- the vacuum toilet includes a toilet bowl 10 , a transfer tank 12 and a flush water tank 14 .
- the flushing water tank 14 has a fill level sensor B02 which is coupled to a valve Q06. If the filling level sensor B02 indicates that there is not enough rinsing water in the rinsing water tank 14, the valve Q06 is opened and the rinsing water tank 14 is filled via a rinsing water line 20 coming from a fresh water reservoir.
- the flushing water tank 14 is designed and connected in such a way that a flushing process is triggered when the toilet is actuated.
- compressed air is conducted via a compressed air line 22 coming from the compressed air source 21 via a flushing valve Q01 and a valve 24 into the interior of the flushing water tank 14 .
- flushing water is conveyed from the flushing water container 14 into the toilet bowl 10 via a first flushing water line 16 .
- the supply of compressed air to the flushing water tank 14 is stopped, whereupon the setting of the valve 24 changes.
- the transfer tank 12 is designed and connected in such a way that after the flushing process, the inlet valve Q05 is opened and suction mass is sucked out of the toilet bowl 10 into the transfer tank 12 using a vacuum applied to the transfer tank 12 .
- the inlet valve Q05 is then closed again and an overpressure is generated in the transfer tank 12 .
- the outlet valve Q04 is then opened and the suction mass located in the transfer tank 12 is conveyed by the overpressure applied to the transfer tank 12 into a waste water reservoir connected to the transfer tank 12 .
- the vacuum or the overpressure in the transfer tank 12 is controlled via the pressure valve Q02 and the vacuum valve Q03.
- a second flushing water line 18 is connected in such a way that it is fed through the first flushing water line 16 .
- the second flushing water line 18 has a controllable valve Q07 which can release or block the flow of flushing water in the second flushing water line 18 .
- the controllable valve Q07 opens the second flushing water line 18, flushing water is conveyed into the transfer tank 12 and the transfer tank 12 is flushed.
- the second flushing water line 18 branches off from the first flushing water line 16 via a connection in the form of a T-piece 17 .
- the flushing water of the first flushing water line 16 flows z. B. into the vertical branch of the T-piece shape 17 and is divided into two flushing water streams in the T-piece shape 17 by one flushing water flow, which continues to form the flushing water flow of the first flushing water line 16, e.g. B. through the left horizontal branch, and the second flushing water flow, which forms the flushing water flow of the second flushing water line 18, flows out through the right horizontal branch of the T-piece mold 17.
- FIG. 2 shows an embodiment of the present invention in which the first flushing water line 16 is also provided with a controllable valve Q08.
- the two controllable valves Q07 and Q08 can be controlled independently of one another. This allows the flow of flushing water to be routed in different ways. If the valve of the first flush water line Q08 is opened and the valve of the second flush water line Q07 is closed, flush water can flow from the flush water tank 14 into the toilet bowl 10 but not into the transfer tank 12 . If the valve of the first flush water line Q08 is closed and the valve of the second flush water line Q07 is open, flush water can flow into the transfer tank 12 but not into the toilet bowl 10 . If both valves Q07 and Q08 are open, flushing water can flow into the transfer tank 12 and into the toilet bowl 10.
- FIG. 3 shows a vacuum toilet in which the controllable valve of the second flushing water line Q07 is designed as a 3/2-way valve.
