Abstract

FIELD: human vital needs satisfaction.

SUBSTANCE: group of inventions refers to sanitary equipment. The public toilet comprises a toilet (2) with a flushing cistern (1) which is connected by a conduit (9) to the drain holes of the washbasins (10, 11, 12) and contains a device by which the flush tank (13) of another toilet (15) is connected with drain holes of the washbasins (10, 11, 12) by a supply pipe (21). The device includes a supply line (21) with the flushing cistern (1) containing the device filled in and turns it off when the flush tank (1) is empty. Filling of each subsequent flushing tank (13 and 14) with waste water is carried out sequentially after filling the previous flushing tank (1). Flushing tanks (1, 13, 14) of all or part of the toilets (2, 15, 16) are connected to the water supply system (6) through the supply line (5, 19, 20). In this method the public toilet is used for the dispatch of natural needs. In this case the described above toilet is used.

EFFECT: reducing the consumption of clean water, improved sanitation, reducing the incidence of infectious diseases, creating a more comfortable environment for users.

Description

The invention relates to sanitary equipment, namely, to stationary and mobile public toilets, and can find application in catering, railway stations and airports, in crowded places.

A public toilet is known, including washbasins and toilet bowls with flush tanks (patent RU 2495981 C2, E03D 7/00, publ. 10/20/2013, bull. No. 29). However, the disadvantage of this public toilet is the high consumption of water. The specified public toilet is the closest in technical essence to the proposed invention and adopted as a prototype.

The invention was set the task of reducing water consumption, improving hygiene, creating more comfortable conditions for users, reducing the cost of a public toilet and the cost of its operation. EFFECT: reduced consumption of clean water, increased hygiene, reduced incidence of infectious diseases, creation of more comfortable conditions for users, reduced operating costs.

The technical result is achieved due to the fact that a public toilet, including washbasins and toilets with flush tanks, contains a toilet with a flush tank, which is connected by a pipe to the drain holes of the wash basins and contains a device by which the flush tank of the other toilet is connected by a supply pipe to the drain holes of the wash basins and which turns on the inlet pipe when the flush tank containing the device is full, and turns it off (off) when the flush tank is empty, when In this case, the filling of each subsequent flushing tank with waste water is carried out sequentially after filling the previous flushing tank, and the flushing tanks of all or part of the toilets for guaranteed filling, including waste water, are connected to the water supply system via a supply pipe. The inclusion of the pipeline means its transition to a conductive state in which the working medium moves through the pipeline containing the device. Disconnection means putting it into a non-conductive state, in which the working medium does not move along the pipeline containing the device.

As a device, a float valve is used.

In FIG. 1 conventionally shows a flushing tank; in FIG. 2 - public toilet.

The flushing tank 1 to the toilet 2 contains a supply valve 3 with a float 4 for supplying clean water via a supply pipe 5 from a water supply system 6, a supply valve 7 with a float 8 for supplying waste water through a pipe 9 from wash basins 10, 11, 12 to the flushing tanks 1 , 13, 14 toilets 2, 15 and 16, respectively.

The flushing tank 1 includes a float valve 17 with a float 18. The float valve 17 is in an open (on) state, passing the wastewater from the wash basins 10, 11, 12 to the flushing tanks 13 and 14 when the flushing tank 1 is full, and disconnected, not letting the spent water condition with an unfilled flushing tank 1.

The flushing tank 13 is connected to the water supply system 6 by the supply pipe 19, and the flushing tank 14 is connected to the supply pipe 20. The flushing tank 13 is filled with waste water from the wash basins 10, 11, 12 through the pipe 21 after filling the flushing tank 1 with the spent water through the pipe 9. The receipt of the spent water in the flush tank 14 is regulated by a float valve (device) installed in the flush tank 13.

A public toilet is used as follows.

The flushing tank 1 is filled with waste water from the washbasins 10, 11 and 12 and used as intended to flush the toilet 2. If the wastewater is not sufficient for flushing, then to fill the flushing tank 1, additionally use clean water from the water supply system 6, having previously adjusted the filling level of the flushing tank 1 using a float valve 3.

When using the toilet 2 with flushing tank 1, the waste water is used to the greatest extent, which minimizes the cost of clean water. Therefore, the indicated toilet bowl with flushing tank is the most attractive for users with a small income, since the cost of visiting it will be minimal.

The presence of the toilet 2, the flushing of which is carried out, as a rule, only with water spent in the washbasins 10, 11 and 12, generally reduces the cost of visiting a public toilet and makes a public toilet an economy class toilet.

Based on the load of the toilet and the actual amount of wastewater coming from the washbasins 10, 11 and 12, the flushing tanks 13 and 14 either use only clean water from the water supply system, or add a small amount of wastewater remaining after filling the flush tank 1.

The knowledge that the water used in washbasins is reused to flush the toilet encourages the user to wash their hands more thoroughly, which reduces the likelihood of infectious diseases.

A method of operating a public toilet, including washbasins and toilets with flushing cisterns, is to use a public toilet containing a toilet with a flushing cistern that is connected by a pipe to the drains of the washbasins and contains a device by which the flush cistern of the other toilet is connected a supply pipe with drain holes for washbasins and which includes a supply pipe when the flush tank containing the ystvo, and disables it when unfilled cistern, wherein the content of each subsequent waste water cistern is carried out sequentially after the previous filling a cistern, the cisterns of toilets or parts connected to the water supply system through the supply line.
