MPK V61D 35/00 E OZD 9/04

The utility model relates to the sanitary equipment of vehicles, and more specifically to toilets used in railway cars. It is most advisable to use the proposed toilet system in passenger cars and electric trains, but it can also be used on other vehicles (cars, ships), as well as in city autonomous toilets equipped with feces collection tanks, when it is necessary to solve the problem of combating unpleasant odors.

A toilet system is already known that contains a body forming a toilet room, inside which there is a toilet, the outlet of which is connected to an underground collecting tank and a device for ventilating the room and cavity of the collecting tank (US Pat. No. 3,601821, 1971, sheet 4-300). However, the known toilet system uses natural ventilation, which is not effective enough.

Known toilet systems containing a housing forming a room in which the toilet is located with its flushing system, an underground collection tank and a forced ventilation device communicating with the toilet outlet, made in the form of a communicating outlet cavity of the toilet bowl and a tank with an outside space outside the fume hood in the output part of which a fan is installed (see nanomer, PM No.

16275, V61D 35/00, 2000 or pat. US No. 5575019 Fig. 4-209R, 1992).

The supply of a chimney with a toilet fan installed in it prevents efficient ventilation of the toilet and gas

the noses of the collection tank, which helps to remove unpleasant odors,

however, this system only works effectively when the valve at the toilet outlet is open, and when it is closed (most of the time), the ventilation of the interior is not carried out by the exhaust system.

The objective of the claimed utility model is to increase the comfort for users of the toilet system by increasing the efficiency of removing unpleasant odors from the room, and the technical result is to provide simultaneous ventilation of both the toilet bowl and the collection tank and the toilet room with an exhaust system, regardless of position valve at the outlet of the toilet.

This result is achieved due to the fact that in the toilet system containing the body forming the toilet room, in which the toilet is placed, an underground tank-collector communicating with the toilet outlet and

device for forced ventilation, made in the form of communicating

the outlet cavity of the toilet bowl and the collection tank with the surrounding space outside the chimney, in the outlet of which a fan is installed, the chimney in front of the fan is equipped with a pipe that communicates its cavity with the internal volume of the room.

To prevent air from entering the exhaust pipe into the toilet room, a non-return valve can be installed in the pipe, and a throttle washer can be installed in the pipe, before connecting it to the pipe, setting the ratio of air flow through the pipe and pipe.

To increase the ventilation efficiency, a confuser is installed at the open end of the pipe leaving the room, and a deflector is installed at the outlet of the exhaust pipe.

A possible embodiment of the utility model is shown in the attached drawing, where in FIG. 1 shows a diagram of the proposed toilet system.

The toilet system comprises a housing 1, forming a toilet room 2, in which a toilet 3 is placed with a flush system 4 and a valve 5 (for example, a poppet, with a pedal actuator). The outlet 6 of the toilet 3 is in communication with an underground collection tank 7 having an overflow pipe 8.

The cavity of the outlet 6 of the toilet 3 and the collection tank 7 communicates with the surrounding space by a chimney 9, in the outlet of which a fan 10 is installed.

In front of the fan 10, the exhaust pipe 9 is connected to the pipe 11, which communicates its cavity with the internal volume of the room 2.

In the pipe 11, a check valve 12 can be installed to prevent air from entering the exhaust pipe 9 in room 2, and the exhaust pipe 9, before connecting it to the pipe 11, can be equipped with a throttle washer 13 that sets the ratio of air flow through

exhaust pipe 9 and pipe 11.

To increase the efficiency of ventilation (mainly when the fan 10 is turned off), a confuser 14 is installed on the open (input) cone of the pipe 11, and a deflector 15 is installed at the outlet of the exhaust pipe 9.

When the fan 10 is turned on (which can be dried either manually or automatically), air is sucked both through the exhaust pipe 9 and through the pipe 11, while the ratio of the costs of the air removed together with unpleasant odors is determined, in particular, by the ratio of the exhaust diameters pipes 9 and pipe 11, and more precisely can be installed with a throttle washer 13. The ventilation process is carried out both when the valve 5 of the toilet 3 is open and closed, both through the exhaust pipe 9 and pipe And, creating a comfortable Slovenia for users of the toilet system as well as for other passengers.
