The best option for implementation

The toilet system of a passenger carriage contains a storage tank 1, under the roof of the carriage, with a filling line 2, the outlet of which is connected to a water-pressure device 3 with a check valve at the inlet and a controlled valve at the outlet, which is connected to the toilet flush nozzles 4, the output of which is made in in the form of a U-shaped water shutter 5 connected by a heat-insulated sewer pipe 6 to the input of the storage tank 7 with thermal insulation, heating devices and devices for pumping fecal water, a vacuum unit 8 (which, for example Ep, may include a vacuum pump, an air filter and an air pressure sensor), the output of which is connected to the atmosphere, an automatic control unit 9, the outputs of which are connected to a vacuum unit 8, a water pressure device 3 and a remote toilet flush control organ 10. In the toilet system there is a separate vacuum vessel 11, and in the storage tank 7 a receiving device (compartment) 12, made, for example, in the form of a receiving pipe inclinedly inserted into the storage tank 7, into the upper end part of which a sewer pipe 6 is inserted, the diameter of the receiving pipe is much larger than the diameter of the sewer pipe 6, and in the lower end part of it there is a mechanical check valve 13, which can be installed with

a slight slope (several degrees) towards its opposite end, the input of the vacuum unit 8 is connected to a separate evacuated vessel 11, the input of which is connected to a receiving device (compartment) 13 in its upper part through a moisture separator 14 and a controlled air valve 15, while the upper part of the storage tank 7 has a non-return air valve 16.

Device operation

The device operates as follows.

When preparing the car for operation, the water tank 1 is refilled through the fuel line 2. As a result, water is supplied from their water tank 1 to the water pressure device 3 through its check valve. If it is necessary to flush the toilet 4 by acting on its remote control 10 and using the automatic control unit 9, a water-pressure device 3 is turned on, which creates a certain water pressure in front of its controlled valve, and a vacuum unit 8, which sucks air from a separate evacuated vessel 11 into the atmosphere until a certain level, for example, up to 70 ... 80 kPa, after which, at the signal of its air pressure sensor, the controllable valve at the output of the water-pressure device 3 is turned off and turned on. e through the toilet nozzles they begin to flush it, and after a few seconds the controlled air valve 15 and the air from the receiving device 12 open, through a dehumidifier 14 it is sucked into a separate evacuated vessel 11, while the non-return mechanical valve 13 blocks the flow of air or faecal from the storage tank 7 water (depending on the state of the storage tank 7 - empty or filled) into the receiving device (compartment) 12, while this creates a vacuum of air, which leads to the suction of 4 water into it from the toilet

from a water lock and fecal waters. When equalizing the air pressure in the receiving device (compartment) 12 and a separate evacuated vessel 11, the process stops automatically, with a delay of time to fill the water shutter of the toilet bowl 4 with a new portion of clean water, after which the water-pressure device 3 and its controlled valve, as well as a controlled air valve 15 are automatically switched off by the automatic control unit 9. After that, the toilet is ready for operation again.

The air check valve 16 is used to release excess air into the atmosphere in the storage tank 7 when it is full and prevents it from sucking air from the atmosphere into it when vacuuming the receiving device (compartment) 12.

From the above it is seen that the introduction of a set of distinctive features in the utility model allows you to create a toilet system for a passenger car with a simplified design of the shutter device, with a reduction in power consumption, as in this device, it is necessary to evacuate not the entire volume of the storage tank, but only the volume of its receiving device (compartment), which at the same time eliminates the load on the inside of the storage tank, because it retains atmospheric pressure.

Industrial applicability

A prototype toilet system was developed, manufactured and tested.
