The invention relates to means water, in particular to mixing devices designed for the mixing of water streams with different parameters in water supply systems.

Known mixing devices designed to control the flow of water in water supply networks [1-9].

Known mixer taps [1]regarding the mixing devices designed for mixing various ratios of hot and cold water, and used as shut-off and control device in the water supply systems. Faucet-mixer includes a housing with a mixing chamber, channels, supply of hot and cold water and water drainage channels, locking device, the cover and the switch.

Known water mixer [2]related to hardware plumbing fixtures and used in water supply networks, where the need arises mixing fluid flows with different parameters. Water faucet includes a housing, two valve heads, tube spout, inlet tube, and the tube spout installed in the Central part of the body with the possibility of messages with the mixing zone and the inlet tube is installed in the inlet channels is made in the case.

These [1, 2] or similar [3-9] mixing devices have a number of significant n the flaws. They do not meet the requirements of creating equipment on the principles of energy-saving technologies. The task of the rational use and conservation of the network of water supply systems of industrial and communal enterprises is directly related to the problem of creating plumbing, built on the principles of energy-saving technologies. Application of these mixers as part of the sanitary equipment is a significant, objectively uncontrolled flow of water in water supply systems and a significant over-expenditure of thermal energy required for its heating. Water over-consumption, in particular, is associated with the expiry of water from Slavnoi mixer tube straight stream or through inefficient shower heads.

Another significant disadvantage of these mixers is associated with inability to comply with stricter health and safety standards, which take an increasing number of countries. The fact that these mixers are contact, i.e. they are driven manually each individual user that is becoming more and more undesirable, and in some cases is simply inadmissible.

Closest to the proposed invention is odometery faucet company “DELABIE” [10]. Specified odometery faucet with bancontact the output remote control includes a housing with a mixing chamber and a water switch, inlet tube, slevou tube with output nozzle and transceiver head, Autonomous control and measuring unit, electrically connected with the source and receiver of optical radiation and electromagnetic valves in the water supply. This faucet mixer differs from the above-mentioned devices contactless turning on the water supply. However, it has some significant drawbacks. The specified mixer taps uneconomical as the consumption of water and energy spent on its heating. Large amounts of consumable water tap two reasons: water overuse caused uneconomical output nozzle for water discharge from Slavnoi tube and dosing system, water supply, based on a strictly fixed and unambiguously prescribed time maintain the valve in an enabled state, which determines the electrical circuit of the control and measuring unit. In other words, the design of the nozzle does not help reduce water consumption and its flow is determined by the time it expires, incorporated in an electric circuit, regardless of the availability of the object of processing before transmitting the head of the crane, i.e. hands from under the jet can be removed, and the water will continue to flow from the nozzle Slavnoi tube according to the established electrical circuit time of maintenance of the crane is in the enabled state.

Following the disadvantage of this faucet mixer is its electrical activity. Mixer taps are reported with a self-contained unit located at the periphery by means of an electrical cable, and therefore requires electrical isolation when placing it in areas of high potential. It is known that the breakage of the electrical cable leads to the creation of sparks, causing the faucet mixer is explosive. In addition, the presence of an electric cable makes faucet-mixer vulnerable to hover electromagnetic interference and, as a consequence, rise to unacceptable false inclusions crane.

The objective of the invention is to reduce the consumption of water and heat energy consumed for its heat, ensuring the on condition of the valve only in the presence of a treatment object in the control zone, in the absence of a treatment object in the control zone faucet should be turned off, is a combination of non-contact on/off water supply to the electrical passivity of the crane, its resistance to electromagnetic interference and the appearance of false inclusions, vandal-proof performance sensitive optical elements contactless actuator of the crane.

The technical result is achieved by the fact that in sadomasichism a crane with a contactless remote control, sod is Rasem housing with a mixing chamber and a water switch, inlet tube, slevou tube with output nozzle and transceiver head, Autonomous control and measuring unit, electrically connected with the source and receiver of optical radiation and the electromagnetic valves of the water supply, the output nozzle is made in the form of a centrifugal spray nozzle, forming a cone of fine-dispersed evenly sprayed water, Islena tube configured to accommodate a fiber optic Converter with external modulation optical output end face of which is placed in the transmitting-receiving head Slavnoi tube, and the opposite end face of the optical Converter is connected with the source and receiver of optical radiation, placed in the Autonomous measuring and control unit, electrically connected with the electromagnetic the valves supplying water, with the electric circuit unit is made on the basis of the integrating circuit of accumulation of the signal measurement information.

Efficiency photometering of the crane, i.e. low consumption of tap water, and, consequently, reducing the cost of thermal energy spent on heating the water, is achieved by a new build scheme object detection control. For detection scheme requires two conditions from the object of control: the presence of the object of control in the area identified the Oia and the Commission of the object of control of oscillatory movements, the corresponding oscillatory movements of human hands under the tap. If only the first condition detection circuit will include odometery faucet, but will turn it off after 3 seconds Only in accordance with the second condition oscillatory movements washable man - detection scheme by the integrating the supply chain, which has accumulated the necessary and sufficient signal of the oscillation of the object is transformed into a measuring circuit that monitors the presence of an object and its oscillatory movements. At the end of the process hands from the tap cleaned and measuring circuit generates the control signal solenoid valves on the water supply interruption. In the measuring circuit protects odometery faucet from false inclusions and provides the enabled state of the crane only in the presence of human hands in the washing process. Such a construction of the measuring circuit self-contained units in the proposed sadomasichism the faucet saves water and energy for its heating.

A special role in saving water and heat in the present invention belongs to a centrifugal spray nozzle. The ability of this nozzle is significantly and dramatically reduce the water consumption thanks to its original design is known from [11]. To offer the same image as the attachment on the new used spray characteristics of the nozzle, specifically, the reflective properties of the generated nozzle cone of sprayed liquid. In fact, when the spray nozzle forms the flare (cone) uniform fine liquid.

And this torch (or cone) is uniformly sprayed fine liquid allows fiber-optic Converter confidently distinguish in the detection zone washable hands and at the same time, the essence of the design concept, not to react, not “notice” the torch of sprayed liquid. And it allows you to essentially required to implement the enabled state of the tap while washing hands. Spray nozzles, such as prototype - French mixers firm “DELABIE”, do not allow this effect can be achieved due to the fact that the water flows out of the nozzle straight stream or a stream with a qualitatively low shape and composition of the sprayed water. The appearance before the fiber-optic Converter direct a jet of water with considerable reflection coefficient will be received by the detection circuit as a false object control and 3 with the water supply will be disconnected. Transparent as the torch of our nozzle allows fiber-optic Converter “to see” and the presence of hands in the detection zone and to capture the process of washing, i.e. the desired oscillatory motion. As a result, when on the trainee offer photometering crane is installed and used new dependency and the influence of the reflective properties of sprayed centrifugal atomizer uniform fine water jet torch on detecting ability of fiber-optical Converter and the control and measuring unit as a whole.

Thus, saving water and thermal energy is achieved in two ways: the process of washing hands only in the presence of the past in the control zone and the original design is applied to the nozzle, and it should be emphasized that in both methods the nozzle plays a key role.

In the invention of new solved the problem contactless remote detection and control of object processing.

As a sensitive element used fiber optic with external modulation. To solve problems of the invention need among the many known and possible options for converters to establish and determine the principles necessary for optimal Converter.

From [12] it is known mathematical expression for theoretical calculation of the parameters of optical fiber Converter:

Pand- power optical radiation at the end of the sending light conductor;

Pp- power optical radiation at the end of the receiving light conductor;

a - the radius of the fiber core;

x - the distance between the longitudinal axes of the optical fibers;

NA is the numerical aperture of the fiber;

Z is the distance to the test object on the end face of the light guide;

r-a+r·tgα, α aperture angle of the light guide.

According to the above formula graphs (figure 1) depending on the optical power at the end of the receiving light conductor on the distance to the test object at different parameters and NA of the fiber, the radiation power at the transmitting end of the light guide. We are interested in the impact on the sensitivity of the transducer geometry and NA optical parameters of the fiber, the power at the transmitting end of the light guide.

Diagram 1 built by:

a=200 µm; x=400 μm; NA=0,3; PH=4000 μw

Graph 2 built at:

a=100 μm; x=200 μm; NA=0,3; PH=4000 μw

Graph 3 built in:

a=200 µm; x=400 μm; NA=0,5; PH=4000 μw

Figure 4 built by:

a=100 μm; x=200 μm; NA=0,5; PH=8000 μw

A comparative analysis of the constructed graphical dependences shows that the greatest sensitivity has a fiber optic-based fiber with a small core radius, a large numerical aperture for a considerable amount transmitted through the light power of the optical radiation. These findings formed the basis of the principle of the construction of a fiber-optical Converter with external modulation photometering crane.

According to this principle, fiber optic Converter with external modulation contains transmitting and receiving vitology (or the wiring transmitting and receiving optical fibers), low optical losses, small size core volnovatsa patterns, high numerical aperture, wherein the transmitting optical fiber (or bundle of transmitting optical fibers) should be transmitted optical radiation of high power.

Because Autonomous control and measuring unit connected to the detection area by using fibers which are good insulators, does not require electrical isolation or other means of isolation at the location of the cranes in the field, even if that place is in the area of high potential. The consequence of this electric passivity of the crane is doubtless to be found only in such technical execution of the crane, dignity is an absolute explosion fire safety.

Technical design of the crane on the basis of the fibers ensures its resistance to electromagnetic interference. This advantage is significant and in some cases decisive. The presence of electromagnetic interference leads to an increase in the noise background in electrical information-measuring tract. Because information-measuring path is made on the basis of optical fibers, electromagnetic interference is practically not observed.

Odometery faucet with touchless remote control includes (2) ESAT is 1 with the mixing chamber water 2 and switch 3, the inlet tube 4, slevou tube 5 with an output nozzle, made in the form of a centrifugal spray nozzle 6, and with a receiving-transmitting cylinder 7 for placing the output end of the fiber optic Converter with external modulation, transmitting optic fiber (or harness fiber) 9 Converter 8, the receiving optic fiber (or fiber optic harness) 10 Converter 8, Autonomous control and measuring unit 11 source 12 and receiver 13 of the optical radiation, electromagnetic valves 14.

Odometery faucet with touchless remote control works as follows. In the initial state of the electromagnetic valves 14 are closed, the optical radiation from the source 12 enters the transmitting optic fiber (or fiber optic harness) 9 and with its end located in the transmitting-receiving head 7, is radiated in the open space zone of detection. If the open space of the object of control is not reflected radiation and Autonomous control and measuring unit 11 does not issue a signal to the valve 14. When the detection area of the object of control (at putting the hands to the faucet), you may receive the reflected signal picked up by the receiving end of the fiber (or bundle of optical fibers 10 and passed them to the radiation receiver. Unit 11 processes the Postup is our signal measurement information and issues a control signal to the valve 14 on the water supply to the faucet. This process occurs in the case where the detection area was really hands doing the “cleaning” of the oscillatory motion. If no movement is detected, the block 11 through 3 turns off the water supply. After completion of the actual process of washing hands, when their removal from the area detection unit 11 through 0.5 to stop the water flow.

In the best performance odometery faucet with touchless remote control is made with application of Autonomous control and measuring unit, on the basis of the electric circuit integrates the chain and pulse pumping radiation source AL-119, solenoid valves, and fiber optic Converter of bundles of optical fibers of the multi-component glass with the size of the fiber core 50 μm, a numerical aperture of 0.5, the optical loss of 50 dB/km detection Range (distance from the output end of the transducer to the object of control) was 60 see this particularly noteworthy is the fact that the output end of the fiber optic transducer, placed in the transmitting-receiving head Slavnoi tube made not combined and separate, i.e. receiving and transmitting bundles of optical fibers form a separate information-measuring channels. This is done in order to fulfill the condition vandal-proof crane, tchakirides showed when combined end (having the best performance in terms of detection range of the object of control) the presence of small scratches on the fibers causes a false turn on the tap. The separate execution of the end face of the transducer is the same scratch causes only a reduction of the detection range of the object of control, but does not cause unacceptable false inclusions photometering crane.
