Description

The utility model relates to pipe fittings, in particular to sanitary devices designed for mixing hot and cold water at a given temperature and can be used in water supply systems for showers in industrial and municipal enterprises, as well as in swimming pools and bath and laundry trusts.

Traditional shower units are known (Russian Patent No. 2030522, class E03C 1/04, 1995.03.10 and Russian patent No. 2032798, class E03C 1/04, 1995.04.10) containing pipelines with valves for supplying cold and hot water, a mixer and a watering can.

The disadvantages of such installations are the difficult operation (control) when turning on and off the flow rate and setting the water temperature, since for this you have to manually control two valves, the increased irrational flow rate due to the long time of turning on, turning off and setting the water temperature when the water is not used , as well as with careless water use, when the valves are left open (forget to close), and there is no automatic closing, unsatisfactory hygiene Useful conditions (especially in public places), since hands already washed must close the faucet.

The closest in technical essence is a shower unit (Patent of Russia for utility model No. 69099, class E03C 1/04, 2007.12.10), containing cold and hot water pipes, a locking device connected to the water supply system with a controlled rod connected via a cable to the foot pedal (flooring).

The disadvantage of such installations is the presence of increased humidity in the premises, the presence of steam, as well as wet condensate on the nozzles with cold water, arising due to the temperature difference during the separate transportation of cold and hot water with the subsequent mixing of these flows to a certain average comfortable temperature right in the shower .

The objective of the utility model is to improve operating conditions, reduce water losses and reduce material costs for repair work.

The task is achieved in that in a shower installation including a water mixing and supply system, a watering can and a shut-off valve connected through a cable to a plastic platform, the electronic-controlled water mixing system is made of polypropylene pipes in the form of three circuits interconnected at the outlet of of which there is a temperature sensor electronically connected to a controller controlled by electrovalves installed on bypasses, while the mixed water supply system to the watering can is made single-pipe with the device, lowering conductive pressure and self-cleaning filter.

The figure shows a general diagram of a shower unit.

The shower unit contains a system 1, 2 for mixing and supplying water, a watering can 3, a shut-off valve 4 connected through a cable 5 to a plastic platform 6.

The water mixing system 1 is designed to mix hot and cold water in different ratios to a predetermined temperature. It is controlled by electronics. It consists of three circuits made of polypropylene pipes with a diameter of 50 mm, interconnected, effectively mixes water, controlling the temperature with a temperature sensor 7 located at the outlet of the last circuit. The signal from the temperature sensor 7 is supplied to the controller 8, through which the temperature in the system 1 is set.

System 1 allows you to pass and mix water at a flow rate of 10 to 200 liters per minute. The controller 8 of the system 1 is controlled by two solenoid valves 9 feeding the main flow through the bypass 10.

The system 2 for supplying water to the watering can is made single-pipe with a device 11 for lowering pressure and a self-washing filter 12.

The device 11 is made in the form of a valve with the ability to lower the pressure to 08-1 cm, which significantly affects the water flow, allowing the shower unit, working at low pressure, to achieve water savings of up to 60%.

Self-washing filter 12, built into the distribution plate 13 is designed to purify water. Flushing the filter takes 3-5 seconds, which allows you to wash the system every day. Purified water allows the use of watering cans of any design, increasing its life by 10 times.

The shut-off valve 4 is a spring-loaded conical rod 14 connected through a cable 5 with a plastic platform 6. The valve is placed on the distribution plate 13.

Shower installation works as follows.

Cold and hot water enter the water mixing system 1, where the water is mixed to a predetermined temperature. The temperature is controlled by the temperature sensor 7. The signal from the temperature sensor 7 is supplied to the controller 8, which sets the set temperature in the system 1.

Mixed water is supplied to a watering can of 3 showers. The user, stepping on a plastic platform 6, pulls the cable 5 under the weight of its own weight, thereby lowering the conical rod 14 down and water of a given temperature through the watering can 3 enters the consumer’s skin. At the end of the use of water, the platform 6 is released by the user, the rod 14, under the action of the spring 15, rises and blocks the flow of water into the watering can.

Thus, the proposed utility model is easy to maintain, and the use, in its design of the device, of a lowering pressure made it possible to achieve water savings of up to 60%. Using single pipe

systems in the premises have decreased humidity (lack of steam), according to the calculations of the capital construction department of Severstal-metiz repair work will be reduced by three. The first experiments on the use of a single-tube system gave the desired result in industrial

enterprises, swimming pools, bath and laundry trusts.
