Description

VEHICLE TOILET

The invention relates to sanitary equipment of vehicles, and in particular to toilets used in railway cars, airplanes, buses.

Known toilets of vehicles containing a series-connected toilet bowl with a water lock, a flushing metering device with a flush switch, a collection tank and conveying pipelines 1-5.

The disadvantage of these toilets is their design using only one collection tank. A toilet made in such a constructive manner is very difficult to use in almost real-life conditions.

A vehicle toilet is known containing a toilet bowl, a water tank, a collection tank, a level sensor, a temperature sensor, electric heaters and heat exchangers hydraulically connected by pipelines, the sensors and electric heaters being connected to the electrical network, and the heat exchangers to the vehicle’s heating system.

The disadvantage of this toilet was originally laid in the design scheme of its execution, which has a toilet connected with only one tank-collector. The toilet, made according to such a constructive scheme, has limited, and sometimes impossible practical

implementation. This is clearly shown in FIG. 2 in the description of the utility model. It can be seen from the figure that the collection tank occupies the entire space in the car space under the toilet room. This is the essence of the problem. The fact is that during the operation of the car, carrying out routine and repair work, it is impossible, due to the collection tank, to get to such an important unit of the car as the coupling device. And in practice, due to the maintenance of the towing device of the wagons, the collection tank has to be removed and then re-suspended in its original place in the carriage space.

It is precisely because of this antagonistic contradiction of several regulatory and repair services that railroad workers refuse to use toilets in railway cars made in a constructive way with one collecting tank. In addition, the water exchange and heating systems, equipped with one temperature sensor and one level sensor, have low reliability.

The objective of the invention is to increase the practical applicability and reliability of the toilet of the vehicle.

The specified technical result is achieved by the fact that in the vehicle’s toilet containing a toilet, a water tank, a collection tank, a level sensor, a temperature sensor, electric heaters and heat exchangers, the sensors and electric heaters are connected to the mains and the heat exchangers to

The vehicle heating system according to the invention has a storage tank comprising temperature sensors, liquid level detectors and a flexible flat heat heater electrically connected to the control unit, the storage tank having an outlet through a filter and a fan to the atmosphere and is hydraulically connected through a fecal pump to tank collector, and the tank collector is equipped with temperature sensors, liquid level alarms, flexible flat

the heater has an outlet through the filter into the atmosphere and is hydraulically connected by a pipeline to the toilet, the flush metering system of which contains a hydraulically connected solenoid valve, check valves, valves, a hydraulic accumulator, a water supply pump, a pressure sensor and a water tank equipped with temperature sensors, liquid level detectors and flexible flat heaters, with temperature sensors, liquid level alarms, flash heaters, solenoid valves, electric pumps trically connected to the control unit and the power supply system of the railway carriage.

The invention provides increased practical applicability by changing the design of the toilet of the vehicle. In the claimed technical solution there is an additional storage tank, which allows you to place it in any

a place of the carriage free from other nodes, devices, highways, for example, in the center of the carriage space. The storage tank performs the function of the main waste collection and can have any maximum permissible overall dimensions. The function of preliminary intermediate waste collection is intended to be performed by the collection tank. Due to its intermediate function, its dimensions are very limited, and therefore it can be located in the traditional place of the car space under the toilet room, and at the same time it will not interfere with the maintenance and repair work, in particular, the routine maintenance of the carriage hitch device that is relevant for railway workers. The proposed constructive design of the toilet removes the contradictions between various repair and maintenance services, the customer welcomes such a solution to the problem, which is why the practical applicability of the claimed toilet is very high.

Improving the reliability of the claimed technical solution is achieved through the use of several sensors of the same type, which allows the control unit to compare their readings with each other and issue a proven control signal for heating the system or transporting the liquid. In addition, the reliability of the system increases due to duplication by sensors of the same type of their control and measuring functions.

Figure 1 shows a diagram of the toilet of a railway car, figure 2 shows a diagram of the hydroelectric equipment of the toilet room, and Fig. 3 a diagram of the hydroelectric equipment of the storage tank.

The vehicle’s toilet contains a toilet 1, a water tank 2, a collection tank 3, a storage tank 4, a pedal 5, a water supply pump 6, a fecal pump 7, a hydraulic accumulator 8, an electromagnetic valve 9, a chopping knife 10, a filter 11, a fan 12, which are hydraulically connected by pipelines , flexible flat heater 13 pressure sensor 14, temperature sensor 15, liquid level switches 16, non-return valves 17, valves 18, the existing water pipe of the car 19, the water pipe of the car to be carried out 20, the ventilation pipe 21, a control unit (not shown in FIG.).

The toilet of the vehicle is controlled by the control unit. Input signals to the control unit come from sensors, or from the performer when the last pedal of the toilet bowl is pressed. Depending on the input signals, the control unit generates the output signals of the pumps or fans.

The proposed vehicle toilet was tested in real conditions of the expedition, showing high reliability. A serial production of the declared vehicle toilet is being prepared.
