The invention relates to installations for cleaning liquid membrane type preferably with a filtration rate of less than 1 liter per minute containing a means for supplying the cleaned fluid, the fluid treatment unit, means for discharge of treated liquid, gravity-flow portable container for receiving treated liquid, means for controlling the filling level of the purified liquid, and a device to control the flow of purified liquid.

The LEVEL of TECHNOLOGY

At the request of US 20070045159 from 01.03.2007, B01D 35/14, SHIN-PING LEE, known device for cleaning fluid designed for placement under the sink. The installation includes a reverse osmosis unit (50) and the base (11), designed to accommodate the container (15) for purified liquid (Figure 1). The base (11) has an opening (17)through which the treated liquid flows into the container (15), equipped with one-way valve (18). The container (15) consists of a body and a cover (19), hinged on top of the base (11). The container has a handle (151) to transfer without fluid (Figure 4). In the bottom of the container has a hole located correspondingly to the hole (17) in the base (11). In the lid (19) is a tool (191) for draining off excess pressure (excess pressure occurs when the removal of treated liquid by the pump from the container (5) for consumption). The apparatus comprises means (40) control filling level of the purified liquid, having a top element (41) control filling level of the purified liquid, the bottom element (42) control filling level of the purified liquid, and an electronic control unit (20) (Figure 2). The top element (41) control filling level of the purified fluid comprises a float valve, hinged on top of the base (11) and extending inside the container (15). The bottom element (42) control filling level of the purified fluid is located in the base (11). When opening the valve (70)having an electronic switch (60), connected to means (40) control filling level, device management (20) takes on the pump (30) signal about the removal of treated liquid from the container (15) to the valve (70) on consumption. When the tool (40) control filling level of the purified fluid determines that the liquid is on the lower level - control device (20) will signal to activate the pump (30) for injection of fluid into the container (15), which will be up until the treated liquid reaches a predetermined upper limit level, then the pump (30) is disabled. When the tool (40) control filling level of the purified fluid determines that the container (15) there is no liquid, the pump (30) will also be off the N. The unit operates from the network.

Known installation has a number of disadvantages. First, injection of purified liquid in the container (15)and for discharge of treated liquid at the intake to the valve (70) using a pump (30)located in the base (11) install. The presence of the pump (30) complicates the design of the installation and reduces the reliability of its work, because during pumping of the pump (30) of the purified fluid consumption in the untimely determination means (40) the absence of liquid in the container (15) of the pump (30) can burn out, and the installation to fail. In addition, the container (15) is pressurized and does not provide the possibility to transfer it purified liquid after the filtration process, as in the bottom of the container has an opening that remains open during the transfer, which reduces the operational characteristics of the facility for cleaning fluid.

Known device for cleaning liquid membrane type, manufactured by Weil Industrieanlagen GmbH, Germany http://www.rowa-wasser.de/trink_produkt.htm?ID=240&gruppe=48&bereich=2, figure 1, 2). The installation includes a reverse osmosis unit and a portable gravity jug, located in specifically designated for him stand. A cradle connected to the supply line of the purified fluid. The stand is provided with means for determining the weight and the arcuate tubing having in the top Central part of the funnel with the outlet, through which the treated liquid flows into the jug. Installation is connected to the cold water, the reverse osmosis unit is located under the sink, and stand for the pitcher and the arcuate pipe respectively located above the sink. The reverse osmosis unit is connected to the stand by line of purified liquid. Thus, the apparatus for cleaning liquid does not require a storage tank, instead it filters water directly into the jar 1.5 liter, made of durable glass. Depending on the model setup and the fluid pressure in the main line water filling jug is from 5 to 15 minutes, after which the filling process stops automatically. Control of the filling level is carried out by the microcontroller after installing the jar on stand by its weight using the weight set in the stand.

A disadvantage of the known installation is a complex design controls the fill level of the purified liquid, which feeds water into a jug and includes scales. Water supply depends on the level of filling of the jug, which is measured by indirect method - by weight. Scales respond to a mass system "jug+water". If the user instead of the prescribed pitcher accidentally try to use another container, for example the EP pitcher smaller, the amount of liquid required weight to stop filling in the prescribed pitcher may not fit in another smaller volume of the jar and the liquid goes over the edge - this reduces the reliability of the installation for cleaning liquid. Furthermore, the presence of the stationary base of the jug above the sink, takes up most of the space working kitchen area, which is usually the most loaded, which also reduces the operational characteristics of the known installation.

At the request of US 2009/0288999 from 26.11.2009, B01D 61/12, SHIN-PING LEE known device for purification of a liquid by reverse osmosis, powered, i.e. power cord to connect the unit to the wall outlet (Figure 1). The apparatus comprises a block (11) reverse osmosis (Fig 3, 5). The reverse osmosis unit is enclosed in a housing (1)with the installation platform (12), in which there is a hole (13) to yield the purified liquid. On the installation platform (12) is removable pressure container (2), consisting of a body (not shown), the lid (25), a holder (26), islennogo spout (27) and the holes (21) for receiving the purified liquid located at the bottom of the container (2), respectively, the outlet (13) installation of the platform (12).

The plant is equipped with means (3) control of the filling level of the purified fluid. Means (3) control, Ural branch of the nya filling purified liquid consists of a body (311) with a movable magnetic float (312), installed inside the container (2) in its upper part, and two magnetic switches (32, 33), sequentially installed on the inner side of the housing (1) block (11) reverse osmosis. Switches (32, 33) are mounted so that the magnetic float (312)inside the container (2), moving along his body (311), interacts with them (elements controls the fill level of the purified liquid placed in different parts of the installation, namely one inside the container (2), and the other inside the housing (1) block (11) reverse osmosis). Means (3) control of the filling level of the purified fluid is supplied by a microcontroller (34). As the filling of the container (2) level of purified liquid will raise the float (312), is the contact of the float (312) with the switch (33) and generates a corresponding signal to the microcontroller (34), or when the user removes the container (2) from the platform (12) before the end time of the filter is the opposite opening of the NC contact of the float (312) with the switch (32) with formation of the corresponding signal.

The plant is equipped with a device to control the flow of purified liquid is made with the possibility of transition to the open position from the beginning of the filtration process and the inflow of liquid into the container (2) and move to the closed position with concanamycins filter and fluids in the container. Device control the flow of purified liquid is flowing from the valve (23)located in the hole (21) of the bottom of the container (2) and solenoid valve (15)located in the installation platform (12) of the housing (1) block (11) reverse osmosis. When installing the container (2) on the platform (12) rod (231) flow valve (23) abuts against the protrusion (131)located on the platform (12), and a flow valve (23) is opened, the magnetic float (312) comes into contact with the switch (32), feeding through the microcontroller (34) signal to the electromagnetic valve (15) at the beginning of the filtration process (electromagnetic valve (15) moves to the open position). Starts the flow of purified liquid in the container (2) and the filling. As the filling of the container (2) magnetic float (312) comes in contact with another switch (33), feeding the signal to the electromagnetic valve (15) on the termination of the filtering process (electromagnetic valve (15) moves to the closed position). The flow of purified liquid in the container (2) is terminated. The user removes the container (2) from the platform (12), the rod (231) flow valve (23) in the bottom of the container (2) is locked, not allowing the purified fluid to flow from the holes (21) in the bottom. Similarly, the filtering process can be stopped when the container (2) filled incompletely. User CH the bottom of the container (2) from the platform (12), it is breaking the magnetic float (312) with the appropriate switch (32) and a signal to the solenoid valve (15) on the end of the filtration process (prototype).

One of the drawbacks of the known installation is that it has a complex mechanism of interaction between the flow control device of the purified fluid from the tool (3) control of the filling level of the purified liquid, require two valves (23, 15) and the magnetic float (312) with two magnetic switches (32, 33), which complicates the design of the installation for cleaning liquid. Another disadvantage is that functionally interconnected magnetic elements controls the fill level of the purified liquid are located in different parts of the installation (magnetic float (312) is located in the container (2), and switches (32, 33) inside the housing (1) block (11) reverse osmosis respectively). In different parts of the installation are also functionally connected to the valve device to control the flow of purified liquid (flow valve (23) is located at the bottom of the container (2)and solenoid valve (15) inside the installation platform (12) of the housing (1) block (11) reverse osmosis), which together reduces reliability in its operation. Another disadvantage of the known installation is that,for example, in the container (2) by chance may get some part, such as a grain of sand, which during the filter can become clogged in the flow-through valve (23)located in the bottom of the container (2), and during the removal of the container (2) from the platform (12) flow valve (23) may not be closed completely and the treated liquid will seep through the bottom. This also reduces the reliability of the installation for cleaning liquid. In addition, the unit is designed for placement above the sink, for example, on the surface of the working kitchen area, which, as a rule, is the most loaded. The availability of a platform for installation of the container increases the size of the machine and does not allow you to place the main unit (11) cleaning under the sink, which reduces the operational characteristics of the facility for cleaning fluid.

As membranes are used, for example, reverse osmosis membrane or nanofiltration membrane. Drain in drainage is through line 9, which is equipped with a restrictor (not shown) in order to create the necessary process for filtering fluid pressure inside the membrane unit 8. Highway 10 connects hydraulically operated shut-off valve 6 and the tool 3 for discharge of treated liquid and is intended to provide feedback on the press the s (liquid) between the device 4 to control the flow of treated fluid and hydraulically operated shut-off valve 6. Unit 2 cleaning fluid is designed for filtration of liquid and is installed under the sink.

The means 3 for discharge of treated liquid, connected to the output of block 2 cleaning liquid, made for example in the form of a flexible hose or tube having sufficient rigidity. The length of the hose or tube is at least 25 see Tool 3 for discharge of treated liquid can be made in the form of a double pipe or double tube - inner (main)for the supply of the purified liquid, and the outer (protective), to protect the inner tube from damage in the event of any inaccurate operation by the user tools 3.

The device 4 to control the flow of purified liquid includes a control valve and connecting means 11 (Fig.7). The control valve is performed, for example, in the form of a mechanical valve 12 (Fig.9), mechanical valve with a valve (not shown) or solenoid valve (not shown). The valve 12 has a seat 13 and a spring-loaded movable rod 14, the spring 15 provides the force for fast switching device 4 to control the flow of purified liquid in open or closed position. The connecting means 11 is designed for the connection device 4 control the flow of purified liquid from the container 5 and consists of adapter 16 with the housing 17, and item established what I performed, for example, in the form of a gate trench 18 or locking protrusion (not shown) on the outer side of the housing 17 of the adapter 16 (Fig.9).

The connecting means 11, in particular, the adapter 16 is located at the output means 3 for discharge of treated liquid. Output means 3 for discharge of treated liquid is mounted above the sink (Figure 5) so that the tool 3 for discharge of treated liquid may be adjustable in length, which increases the convenience of operation of the installation for cleaning liquid membrane type, i.e. the user, clasping the connecting means 11 by the hand and pulling him can pull the tool 3 for discharge of treated liquid to the required length (unit 4 control the flow of purified liquid is moved together with the tool 3 for discharge of treated liquid) and connect the device 4 to control the flow of purified liquid from the container 5 (6) for filling the container with purified liquid in any chosen location for example the kitchen area. After detaching device 4 to control the flow of purified liquid from the container 5, the user removes the portion of the means 3 for discharge of treated liquid, which was stretched out, back under the sink and sets the connecting means 11 to its original place above the sink. Also for the convenience of operation of the installation can be productrepository length for the tool 3 for discharge of treated fluid for retracting it under the sink, made in the form of weighting 19 (Figure 5, 6) or automatic retracting device (not shown), which will also be located under the sink. Retainer length can also be used as a limiter pulling means 3 for discharge of treated liquid, as seen in Figure 5, 6 for example, the filler 19. To further improve performance installation tool 3 for discharge of treated liquid may be additionally provided with decorative clamping and guiding means 20 located above the sink (Figure 5, 6).

The container 5 includes a housing 21, a cover 22 and an additional element 23 to install the device 4 to control the flow of purified liquid (Fig.7). The container 5 may be made in the form of a tank, bottle, jar or container of any shape, in particular capacity jug type. The element 23 to install the device 4 to control the flow of purified liquid consists of a housing 24 (Fig.9) from the installation cavity 25, communicating with the container 5 through the opening 26, and areas of emphasis made in the form of a protrusion 27 or plate (not shown), limiting the depth of installation of the device 4 to control the flow of purified liquid in the container 5. The element 23 to install the device 4 to control the flow of purified liquid can be made as separate parts (h is Rajah not shown) or in one piece with the container 5 (Fig.7-10). The element 23 to install the device 4 to control the flow of purified liquid may be provided with a fastening element (not shown) for additional fixing device 4 in the housing 24. The fastening element may be in the form of a protrusion on the inner side of the housing 24 of the installation cavity 25, the retaining device 4 by means of the friction force on the housing 17 of the adapter 16, or in the form of notches on the housing 24 of the installation cavity 25, is able to interact with the tab on the housing 17 of the adapter 16 (bayonet mount).

The means 28 controls the fill level of the purified liquid is placed in the cleaning unit (not shown) or in the container 5 (7) and consists of a level sensor of the purified fluid and connected to the actuator. The actuating element is designed as a lever mechanism 29 (7) or control unit (not shown). A lever mechanism 29 is a lever 30, fixed in the housing 21 (not shown) or in the lid 22 of the container 5, in particular, in the case of 24 item 23, made in one piece with the container 5 (Fig.9), with the possibility of rotation around the axis 31 (Fig.9). One end of the lever 30 has a fastening element, made for example in the form of locking tabs 32 (Fig.9), interacting through geometric circuit with shut-off is padini 18 connecting means 11, or Vice versa in the form of locking depressions (not shown)capable of interaction through geometric closures from the locking protrusion of the connecting means 11 (not shown). The locking protrusion 32 ensures the fixation of the adapter 16 in the housing 24 of the element 23, while holding the stem 14 of the valve 12 open (Fig.9), and the liberation of the adapter 16 from the locked end of the filtering process (Figure 10).

If the control valve is made in the form of a mechanical valve with a valve pivoted in the housing 17 of the adapter 16 (not shown), the locking tab 32 also will capture and hold the valve open during the entire filtration process, thus fixing the adapter 16 in the container 5 can be made to move the valve in open position, for example, by a bayonet connection of the housing 17 of the adapter 16 with item 23 of the container 5 under the action of physical effort from the user. Accordingly, detach bayonet adapter 16 from the element 23 of the container 5 (not shown) may also be carried out under the action of the physical effort of the user after switching the valve to the closed position (not shown).

The other end of the lever 30 is connected to the level sensor of the purified liquid, which JW is AESA sensor float type made in clear float 33 (7, 8) or private float (not shown), or a torque sensor type (not shown). The torque sensor type (not shown) may include a spring disposed on the outer side of the bottom of the container 5, with one end of the lever 30 will extend beyond the housing 21 of the container 5 and rests against a flat surface on which the container 5. As the filling of the container 5 fluid, the spring will be compressed, and rests on the flat surface end of the arm 30 will be actuated lever mechanism 29.

The lid 22 of the container 5 must be additionally coupled with the housing 21 (not shown) or to have a certain mass, which would not permit the lever 30 to push or displace the lid 22 of the container 5 in the process of their work. Additional clutch cover 22 to the housing 21 may be, for example, by means of fixation, made in a special tab on the lid 22 and the special cavity of the housing 21, or Vice versa (not shown).

Part of the lever 29 can extend beyond the cover 22. The protruding portion may be made as separate parts, for example in the form of a button (not shown) capable of interaction with the ne end of the lever, or in the form of a protruding part 34 (Fig.7-10) of the lever 30 so that the user by pressing the protruding portion 34 of the lever 29 may release the adapter 16 from fixing regardless of the position level of the purified liquid in the container 5, i.e. to stop the filtering process at any time.

The actuating element may be designed as a control unit with a power source, the output of which is connected to the input of the control unit (not shown). The control unit and level sensor purified fluid interconnected. Level sensor purified liquid is a conductivity sensor or a proximity sensor (not shown). The control unit is located in the container 5 (not shown), or in the unit 4 control the flow of purified liquid (not shown) and provided with a fastening element, an input connected to the output of the control unit.

If the control unit is located in the container 5, for example, in the case of 24 item 23 (not shown), the fastening element may be in the form of electrically controlled locking ledge or electrically-controlled locking depressions (not shown)capable of interaction through geometric circuit with shut-off cavity 18 or locking protrusion (che is the intellectual property not shown) respectively on the outer side of the housing 17 of the adapter 16. Similarly, the locking projection 32 (Fig.9, 10) electrically operated locking tab ensures the fixation of the adapter 16 in the container 5, while holding the stem 14 of the valve 12 open and release adapter 16 from the locked end of the filtration process (not shown). Or if the control valve is made in the form of a mechanical valve with a valve pivoted in the housing 17 of the adapter 16 (not shown), electrically-controlled locking tab, similar to the locking projection 32 will be retained in the filtration process, the valve open, thus fixing the adapter 16 in the container 5 can be made to move the valve in open position, for example, by a bayonet connection of the housing 17 of the adapter 16 with item 23 of the container 5 under the action of physical effort from the user. Accordingly, detach bayonet adapter 16 from the element 23 of the container 5 may also be carried out under the action of the physical effort of the user after switching the valve to the closed position (not shown).

If the control unit is located in the device 4 to control the flow of purified liquid, for example in the housing 17 of the adapter 16 (not shown), the fastening element control unit may be in the form of electrically controlled fixiruyem the ledge, also located on the outside of the housing 17 of the adapter 16 and is capable of holding device 4 to control the flow of purified liquid in the container 5 is in the open position due to the friction force resulting from contact of the projection with the inner side of the housing 24 item 23 (not shown).

If the control valve is made in the form of an electromagnetic valve, its input is connected to the output of the control unit. The solenoid valve can be located in the housing 17 of the adapter 16 and is connected to the control unit via contacts (not shown) or on the tool 3 for discharge of treated liquid and is connected to the control unit through contacts or radio (not shown). If the solenoid valve is located on the tool 3 for discharge of treated liquid, the installation for cleaning liquid can be further provided with a safety valve located within the housing 17 of the adapter 16 of the connecting means 11 (not shown).

The control unit is equipped with a position sensor, the input signal to the control unit of the connection device 4 to control the flow of purified liquid from the container 5, and accordingly it disconnecting. The position sensor and the control unit are connected by contacts or by radio. Position sensor mo is et to be an optical sensor or switch (button). If the position sensor is made in the form of a micro switch (button)located on the outside of the housing 17 of the adapter 16, he may additionally hold the device 4 to control the flow of purified liquid in the open position due to the friction forces that occur when the contact surface of the button with the inner side of the housing 24 item 23 (not shown).

The control unit may be further provided with a button (not shown) to signal to the control unit exemption adapter device 16 4 control the flow of purified liquid from fixation. The button may be located, for example, on the housing 21 and the lid 22 of the container 5, and the exit button is connected to the input of the control unit. The user by pressing the button can release the adapter 16 from fixing regardless of the position level of the purified liquid in the container 5, i.e. to stop the filtering process at any time.

Thus, the tool 28 to control the filling level of the purified fluid is located in block 2 of cleaning fluid (not shown) or in the container 5 (Fig.7, 8).

Installation for cleaning liquid membrane type can contain tool salinity (not shown) for enrichment of minerals of the liquid which has passed the cleaning in the cleaning unit 2 is fluid. The tool mineralization performed, for example, in the form of individual granules of mineralizer, a perforated container filled with the mineralizing composition, or package with the mineralizing composition, as well as in the form of a unit dosage of the mineral concentrate. Depending on the modification of the installation tool mineralization may be located in any part thereof, for example in unit 2, the cleaning liquid container 5.

Installation for cleaning liquid may contain an indicating unit for determining the state of a resource, at least one filter element unit 2 cleaning fluid (not shown). The display device, preferably, is located in the upper part of the body or lid of the container 5.

Installation for cleaning liquid can be made of various modifications, including to include additional blocks both before and after the block 2 cleaning fluid, such as sorption, ion exchange, as well as modules and cartridges filled with special resins (e.g., antibacterial), ultraviolet sources.

Installation for cleaning liquid membrane type operates as follows.

The source device 4 to control the flow of purified liquid is in the closed position out of communication with the container 5 (Figure 5). To obtain a purified liquid will is executed, the user pulls the tool 3 supply of treated liquid, the output of which is located on the device 4 to control the flow of purified liquid is mounted above the sink, to the desired length (Figure 5, 6). To begin the filtering process and the inflow of liquid into the container 5 of the device 4 to control the flow of purified liquid is put in the open position, the user physical force should enter (put) the adapter 16 of the device 4 to control the flow of purified liquid into the housing 24 of the element 23 of the cover 22 of the container 5.

If the actuating element is designed as a lever mechanism 29, when the user of the adapter 16 into the housing 24 of the element 23 of the lever 30 leans back, letting the adapter 16 into the cavity 25, the stem 14 of the valve 12 rests on the ledge 27, the spring 15 due to its compression provides the lifting rod 14 simultaneously with the transfer device 4 to control the flow of purified liquid in the open position, at this point, the locking projection 32 of the lever 30 is in the locking cavity 18, locking the adapter 16 from longitudinal movement and holding device 4 to control the flow of purified during the filtration of the liquid in the open position by the weight of the float 33. Thus, the device 4 to control the flow of purified liquid in the open position is in a spring loaded condition. If the control valve device 4 control is the exercise by the flow of purified liquid is made in the form of a mechanical valve with a valve, when the user of the adapter 16 into the housing 24 of the element 23, the user simultaneously performs the bayonet connection of the housing 17 of the adapter 16 with the body 24 of the element 23, the lever 30 when it leans back, letting the adapter 16 into the cavity 25.

When returning the lever 30 to its original position, its locking tab 32 is in contact with the valve and opens it, holding during the filter in the open position by the weight of the float 33.

If the actuating element is designed as a control unit, when the user of the adapter 16 into the housing 24 in the case of a mechanical valve 12 and its rod 14 abuts against the protrusion 27, the spring 15 due to its compression provides the lifting rod 14 simultaneously with the transfer device 4 to control the flow of purified liquid to the open position when the compression spring 15 and the control unit by a signal from the position sensor sends a signal to the electrically-controlled locking tab on the entrance of the isolation trench 18. Electrically-controlled locking tab is in the locking cavity 18, locking the adapter 16 from longitudinal movement and holding device 4 to control the flow of purified during the filter in the open position. Thus, the device 4 to control the flow of purified liquid in the open position is in a spring loaded condition. the case of mechanical valve with valve when the user of the adapter 16 into the housing 24 of the element 23, the user simultaneously performs the bayonet connection of the housing 17 of the adapter 16 with the body 24 of the element 23. Then the electrically-controlled locking tab on a signal from the control unit comes in contact with the flap, opening it and holding during the filter in the open position by the weight of the float 33. If the control valve is made in the form of an electromagnetic valve, when the user of the adapter 16 into the installation cavity 25 by the signal from the position sensor, the control unit sends a signal to the solenoid valve about his transition to the open position and electrically operated simultaneously on a ledge about fixing adapter 16 from longitudinal movement in the installation cavity 25 of the container 5. In this case, the signal on the transition of the electromagnetic valve in the open position can be carried out after fixation of the adapter 16. If the control unit is located in the housing 17 of the adapter 16 (or in unit 2 cleaning fluid), fixation of the adapter 16 can be due to friction resulting from contact electrically-controlled locking tabs (located on the outside of the housing 17 of the adapter 16) with the inner side of the housing 24 of the installation cavity 25. If the device 4 to control the flow of purified is hidcote made with the possibility of connection with the container 5 bayonet connection, fixation of the adapter 16 may be carried out under the action of the physical effort of the user (manually).

After opening the control valve fluid under pressure from the drinking water passes through the means 1 for supplying the cleaned fluid, opens hydraulically operated shut-off valve 6 and falls to the input unit 2 cleaning fluid. In unit 2, the liquid flows, for example, in module 7 sorption, where the removal of chlorine, heavy metal ions and organic substances, and further in module 8 with a membrane, where the removal of harmful impurities, bacteria, viruses, mostly dissolved salts and organic substances.

The passage of fluid through the plug 8 with a membrane formed purified liquid and concentrate. Concentrate on line 9 enters the drainage. The purified fluid through the tool 3 for discharge of treated liquid and the device 4 to control the flow of purified liquid flows into the container 5.

As the filling of the container 5, the level of purified liquid 35 (Fig) increases and reaches its specified maximum value. Level sensor purified liquid sends a signal to the actuating element of the device control the flow of purified liquid in the closed position.

If the actuating element is designed as ricain the mechanism 29, the level of purified liquid raises the float 33, thereby rotating the lever 30 and releasing the adapter 16 from fixation (Figure 10). Under the action of the spring 15 and the adapter 16 otmelivaetsja, disconnecting the device 4 to control the flow of purified liquid from the container 5 simultaneously with the closing of the valve 12. If the control valve is made in the form of a mechanical valve with the valve and the adapter 16 is connected to the container 5 bayonet connection, the level of purified liquid raises the float 33, thereby rotating the lever 30. The locking protrusion 32 ceases to press on the valve and it closes. This exemption adapter 16 from the fixation can be performed manually by the user at any time.

If the actuating element is designed as a control unit, in case of mechanical valve 12 gauge purified liquid registers the specified maximum level of the purified fluid and sends a signal to the control unit exemption adapter 16 from fixation. Electrically-controlled locking tab out of the gate trench 18 and under the action of the spring 15 and the adapter 16 otmelivaetsja, disconnecting the device 4 to control the flow of purified liquid from the container 5 simultaneously with the closing of the valve 12. If the control valve is made in the form of a mechanical valve with the valve and the adapter 6 is connected to the container 5 bayonet connection, the level sensor purified liquid registers the specified maximum level of the purified fluid and sends a signal to the control unit to cease contact electrically-controlled locking tab flap. The protrusion ceases to press on the valve and it closes. This exemption adapter 16 from the fixation can be performed manually by the user at any time. If the control valve is made in the form of a solenoid valve, level sensor purified liquid registers the specified maximum level of the purified fluid and sends a signal to the control unit on closing of the electromagnetic valve and simultaneously about the liberation of the adapter 16 from fixation. In this case, the signal exemption adapter 16 from the fixation may be lodged after the closing of the electromagnetic valve. Exemption from fixation in this case can occur under the action of the physical effort of the user, if the device 4 to control the flow of purified liquid is connected to the housing of the installation cavity bayonet connection.

After the closure of the control valve the flow of purified liquid in the container is stopped, and the filtering process stops, the means 3 for discharge of treated liquid increases the pressure, under which the hydraulically operated locking clap the n 6 is closed (feedback pressure between the valves is carried out through line 10). The user returns the device 4 to control the flow of purified liquid to its original place above the sink (Figure 5) and carries the container 5 for the consumption of purified liquid. Installation for cleaning fluid enters the standby mode. In standby mode, over washing can only output means 3 purified liquid located on the device 4 to control the flow of purified liquid, which, even with extra decorative clamping and guiding means 20 (Figure 5) take up so little space that the surface of the sink remains free. Under the sink can only block 2 cleaning liquid having a small size and does not occupy a lot of space unlike the closest analogue. As required in the purified liquid, the user takes the container 5 and sets it to device 4 controls the purified liquid (6). The cycle repeats.

Unlike most similar analogue, in which the valve device to control the flow of purified liquid, and magnetic elements controls the fill level of the purified fluid located in different parts of the installation, respectively, in the invention, the device 4 to control the flow of purified liquid is an integral part of cleaning fluid, and means 28 controls the level of the floor is to be placed purified liquid located in the container 5, or in unit 2 cleaning fluid, thus achieving simplification of the design of the facility while improving plant reliability during its operation. Design solution provides the convenience and ease of installation and detaching device 4 to control the flow of purified liquid from the container 5, for filling which, in contrast to the nearest analogue, does not require any special installation platform or stand, to move the filled container prevents seepage of treated fluid through the bottom of the container. The filling of the container 5 can be carried out not only on the surface cooking area (above the sink), which, as a rule, is the most loaded, but in any other desired user location kitchen area, resulting in improved performance installation for the purification of liquids.

The container 5, and a lever mechanism 29 and the float 33 is made of plastic material and are in contact with the purified liquid. After some time after the start of operation of the installation for cleaning liquid container 5, and a lever mechanism 29 and the float 33 can be washed with disinfectant separately from unit 2 cleaning fluid, which also improves the operating characteristics of the installation for cleaning liquid is Ty.

Concentrate from the first and second steps is merged and taken for mixing with initial water fed at the input of the first step. Permeate obtained from the first step is taken to the second reverse osmosis step. Permeate from the second step is the end product. When desalinating water from natural sources, the water undergoes pre-settling and mechanical impurities are removed.

EFFECT: invention enables to obtain deeply desalinated water with salt content less than 1,5 mg/l without additional desalination steps, simplifies the process, enables to get rid of secondary effluent and additional chemical agents.
