Abstract

FIELD: construction.

SUBSTANCE: public lavatory includes sinks and toilets with flush tanks. At least one toilet with a flush tank is connected to the drain holes of the sinks through a pipe and has a device with the help of which the flush tank of, at least, one other toilet is connected to the drain holes of the sinks through a supply pipe. The device opens the supply pipe when the flush tank, containing it, is full and closes it when the flush tank is empty. The flush tanks of all the toilets or part thereof are connected to the water supply system through a supply pipe.

EFFECT: reduced consumption of clean water, improved hygiene, reduced number of incidents of infectious diseases, creation of more comfortable environment for users, reduced operation costs.

Description

Economy public toilet. 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 at least one toilet bowl with a flush tank, which is connected by a pipeline to the drain holes of the washbasins and contains a device through which the flush tank, at least one other toilet bowl is connected by a supply pipe to the drain holes of the washbasins, and which opens the supply pipe when the flushing tank containing the device is full and closes it if not filled with flushing cistern, and flushing cisterns of all or part of the toilets are connected to the water supply system by means of a supply pipe.

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 the open state, passing the wastewater from the sinks 10, 11, 12 to the flushing tanks 13 and 14 when the flushing tank 1 is full, and the closed, not allowing the wastewater to pass through, with an unfilled flushing tank 1.

The flushing tank 13 is connected to the water supply system 6 by a supply pipe 19, and the flushing tank 14 is connected to a supply pipe 20. The flushing tanks 13 and 14 are filled with waste water through a supply pipe 21. The flow of waste water into the flushing tanks 13 and 14 is controlled by a float valve (device), installed in the flushing tank 1.

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 only with waste water in the washbasins 10, 11 and 12, in general, 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 waste water used in washbasins is reused for flushing the toilets stimulates the user to wash their hands more thoroughly, which reduces the likelihood of infectious diseases.

The proposed technical solution has novelty, is industrially applicable, is not obvious to a specialist.

Claims (2)

1. Public toilet, including washbasins and toilets with flush tanks, characterized in that it contains at least one toilet bowl with a flush tank, which is connected by a pipeline to the drain holes of the washbasins and contains a device through which the flush tank of at least one other the toilet is connected by a supply pipe to the drain holes of the washbasins, and which opens the supply pipe when the flush tank containing the device is filled and closes it when the flush tank is empty, When in use, flushing cisterns of toilet bowls of all or part connected to the water supply system through the supply line. 2. A public toilet according to claim 1, characterized in that the device is a float valve.
