Description

The invention relates to sanitary equipment, in particular to sanitary units containing toilets with flush tanks and washbasins and / or sinks, and may find application in the toilet rooms of residential, industrial and office premises.

A well-known bathroom containing a toilet with a flushing cistern (patent for utility model RU 88369 E03D 11/02, publ. 10.11.2009).

The disadvantage of this bathroom is the high consumption of clean tap water for flushing the toilet.

The specified bathroom is the closest in technical essence to the proposed invention.

The technical result of the invention is the saving of clean tap water while improving and accelerating the flushing of the toilet, increasing hygiene, preventing intestinal diseases, creating more comfortable conditions for users, improving the health and quality of their lives, saving energy for cleaning and disinfecting water.

The technical result is achieved due to the fact that in a bathroom containing a toilet with a flush tank, into which water from a cold water supply system enters a supply pipe, a wash basin and / or a sink, a supply pipe is connected to a drain neck of the washbasin and / or sink with a pipe containing a check valve, and also made with a valve that stops access to the flush tank of water from the cold water supply system.

By flushing the toilet understand the flushing of the contents of the bowl (inner cavity) of the toilet.

The drawing shows a bathroom.

The toilet contains a toilet 1 with a flushing cistern 2 and a start button 3, a supply pipe 4 with a valve 5 for filling the flushing cistern 2 from a cold water supply system 6 (cold water riser), a pipeline 7 with a non-return valve 8, a wash basin 9 with a sink 10, a drain neck (not shown), pipe 11 with a hole 12 in the wall for draining excess waste water into the sewer.

The bathroom is used as follows.

A valve 5 closes the access of water to the flushing tank 2 from the cold water supply system 6.

In the process of washing, water from a faucet (not shown) enters the sink 10 of the washbasin 9 and through the drain neck, a pipe 11 through a pipe 7, a supply pipe 4 enters the tank 2 and fills it. After filling the tank 2, excess water through the hole 12 in the wall of the pipe 11 goes into a sewer outlet (not shown).

If necessary, flush the toilet, the user presses the start button 3 of the flushing tank 2, after which flushing is carried out.

After flushing the toilet, the user washes his hands, and the flushing tank 2 is filled with waste water from the wash basin 9.

If there is a lack of wastewater in the flush tank 2, open the valve 5 manually or using automatic devices and fill the flush tank 2 with tap water from the cold water supply system 6. The check valve 8 is a device that lets the wastewater pass from the sink 10 of the wash basin 9 into the flush tank 2 and not letting clean tap water from the cold water supply system 6 in the opposite direction to the wash basin 9.

After filling the wastewater tank 2 with the valve 5 with the spent water, the access of tap water to the tank 2 and the pipe section 7 to the check valve 8 are blocked.

Obviously, to use the wastewater from the sink, for example, after washing the dishes, it is necessary to install cleaning filters to prevent unwanted impurities and impurities from entering the flush tank, which could damage it.

The cessation of access of water from the cold water supply system to the flushing tank is carried out in manual mode or in automatic mode using automation equipment.

The greatest economic effect of the proposed technical solution will be achieved if the washing of the hands by the user is carried out both before and after using the toilet, which will be an additional prevention of various intestinal diseases.

In addition, the effectiveness of this technical solution will increase dramatically when automating the opening and closing of the valve 5, depending on the level of water in the flushing tank 2 and / or on the toilet 1 or in the user's toilet room.

In the presence, for example, on the toilet 1 or next to it in the user’s toilet room, the flushing tank 2 must be filled either with waste water, or, in its absence, with clean water from the cold water supply system. This requires the presence of appropriate sensors, namely a water level sensor in the flush tank 2 and a user presence sensor on or near the toilet.

It is possible to install automation, providing closing of the valve 5 in the presence of waste water in the pipeline 7.

When a signal appears on both sensors, a signal is sent to trigger an output trigger device that is electrically connected to the sensors, namely, the mechanism for turning valve 5 into an open or closed state.

In this case, the valve 5 either stops access to the flushing tank 2 of water from the cold water supply system 6, or ensures its free flow into the flushing tank 2.

In the case when the ingress of waste water into the flushing tank 2 is undesirable, and the pressure in the cold water supply system 6 is not enough to prevent the waste water from entering the flushing tank 2, into the pipeline 7, connecting the supply pipe 4 to the drain (s) the neck (s) of the washbasin and / or sink, install an additional valve.

An additional valve in the closed position eliminates the ingress of waste water not only into the flushing tank 2, but also when the valve 5 is open, into the cold water supply system 6 in the absence of water.

The method of operation of the bathroom, including its use for sending natural necessities, is that the dispatch of natural necessities is carried out in the bathroom considered above.

Saving clean tap water is carried out by reducing its need for flushing the toilet. Improving hygiene and accelerating flushing is achieved by using warmer water to flush the toilet.

Energy savings for cleaning and disinfecting water are obtained by reducing the amount of clean tap water to flush the toilet.

The creation of more comfortable conditions for users and the improvement of their quality of life is facilitated by an increase in the ambient temperature due to the appearance of warmer waste water in the toilet flush cistern, saving money on the cost of tap water.
