DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the use of a water purifier having a hinge with an ASV according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 7, after the frame 14 is brought into close contact with the wall surface of the kitchen or the inside of the sink, a fastening hole 32 of the frame 14 is fastened to a screw (not shown) And is fixed by hanging.

The connector (5, 6, 7, 8) is connected to the frame (14) by the side and side hinges (16, 18) and the hinges (9, 10, 11) (14).

That is, the rocker 26 formed on the bottom of the side and side hinges 16, 18 and the hinges 9, 10, 11 corresponds to the locking hole 25 formed through the bottom of the coupling part 12 ). At this time, the locker 26 can be prevented from disengaging from the locking hole 25 by the separation preventing jaw 27 protruding from the outer surface of the lower end of the locker 26.

The side and side hinges 16 and 18 and the hinges 9 and 10 and 11 are attached to the coupling part 12 of the frame 14 so that the side hinge 16 and the side hinge 16, 6, 7, 8 can be rotatably fixed to the frame 14 by the hinges 9, 10, 11, respectively.

When the connectors 5, 6, 7, 8 are rotated upward to lift the first angle restricting jaw 28 formed on the connectors 5, 6, 7, 8, (1, 2, 3, 4) coupled to the connectors (5, 6, 7, 8) are mounted on the upper surfaces of the hinges (9, 10, 11) . Accordingly, it is not necessary to apply an excessive external force to the connectors 5, 6, 7, 8 and to rotate the connector 5, 6, 7, 8 upwardly beyond an unnecessary angle.

Therefore, the connectors 5, 6, 7 and 8, which are rotated within an angle between the vertical direction (which refers to the initial position) and the horizontal direction (the maximum angle at which the connectors 5, 8) can be combined with the water filters (1, 2, 3, 4).

In this case, when the openings of the water filters 1, 2, 3, 4 are coupled to the connectors 5, 6, 7, 8 and rotated in one direction at an arbitrary angle, 3, 4) are seated in the engaging grooves 34 formed in the connectors 5, 6, 7, 8 in a corresponding manner.

Accordingly, the water filters 1, 2, 3, and 4 can be detachably coupled to the connectors 5, 6, 7, and 8. At this time, the check valve 24 supported by the compression coil spring in the connector 5, 6, 7, 8 is pushed upward by the upper end of the opening of the water filter 1, 2, 3, (At this time, the compression coil spring is subjected to a compressive force).

Therefore, the raw water can be introduced into the water filter (1) through the fluid transfer passage (23) of the connector (5) through the hose (15) connected to the intake side hinge (16).

On the other hand, when separating the water filters 1, 2, 3, 4 from the connectors 5, 6, 7, 8, the water pressure of the raw water flowing into the connector 5 and the elastic restoring force The check valve 24 is returned to the initial position by the check valve 24 to shut off the fluid transfer passage 23. This makes it possible to prevent leakage of water from the connectors (5, 6, 7, 8) when the water filters (1, 2, 3, 4) are separated from the connectors .

On the other hand, when the connectors 5, 6, 7, 8 coupled with the water filters 1, 2, 3, 4 are rotated in the vertical direction of the initial position, The formed second angle restricting jaw 28 is brought into close contact with the bottom surface of the fastening portion 12. Accordingly, the water filters (1, 2, 3, 4) coupled to the connectors 5, 6, 7, 8 can maintain the vertical direction.

(1, 2, 3, 4) are detachably coupled to the connectors (5, 6, 7, 8) and a structure in which the hoses (15) coupled to the intake side hinges (1, 2, 3, 4) connected in series and the purified water purified water is passed through a hose (17) coupled to the outgoing side hinge (18) Or the like is the technical content used in the related art, and thus a detailed description thereof will be omitted.

5, when the water filter 3 is an RO filter, concentrated water filtered by the water filter 3 is supplied to the hose 35 connected to the hose connector 3a of the water filter 3 Can be discharged through a sink. In this case, when the power switch is turned off, the purified water purified by the water filter 3 is sent to the water storage tank 19 through the hose 36, The condensed water filtered by the condenser water is discharged to the sink through the hose connected to the hose connection port 3a because it is a technical content used in the technical field of the present invention.

The amount of purified water purified by the water filter 3 (referred to as RO filter) becomes relatively small compared to the amount of concentrated water to be treated. When the purified water is not used by the faucet A or the like, the purified water purified by the water filter 3 is stored in the water storage tank 19, and then purified water is discharged from the water storage tank 28 when necessary .

At this time, the purified water stored in the water storage tank 19 is passed through the water filter 4 and supplied to the faucet A or the like to remove the odor from the water and improve the water taste.

On the other hand, when the constant stored in the water storage tank 19 is full, the ASV 22 can prevent the water from being introduced into the water filters 2, 3, 4 side.

When the pressure of the water storage tank 19 exceeds the set pressure (the ASV 22 is connected to the constant flow hoses 36 and 37 between the water filter 3 and the water storage tank 19) The pressure of the water storage tank 19 can be detected by the pressure of the water storage tank 19 when the water level is high in the water storage tank 19 22c to the on state. The passage between the inlet side flow path 20 connected to the water filter 1 and the water outlet side flow path 21 connected to the water filter 2 is blocked by the movement of the plunger 22c.

Therefore, when the constant stored in the water storage tank 19 becomes high and a pressure exceeding the set pressure is generated, the water filter (1) is removed from the water filter (1) by the ON operation of the plunger (22a) It is possible to automatically shut off the raw water to be transferred to the washing machine 2.

Therefore, when raw water is continuously treated by the water filter (1, 2, 3, 4) in a state where the inflow of purified water into the water storage tank 19 is blocked, purified water is supplied to the sink It can be prevented from being discarded and wasted.

As described above, when the constant stored in the water storage tank 19 is flooded, the ASV 22 blocking the introduction of the raw water into the water filter (1, 2, 3, 4) For example, a hinge connecting the first connector 5 and the second connector 6 in a communicative manner).

As a result, the ASV (22) is unified with the hinge (9) to simplify the shape, thereby reducing the cost of manufacturing the ASV (22) and reducing the number of assembling work processes, thereby improving productivity.

In addition, since the ASV 22 and the hinge 9 are unified, the assembled parts of the components are reduced, thereby preventing the generation of leaks through the assembled part gaps.

When the pressure exceeding the set pressure is generated in the water filters 1, 2, 3, 4, the hinge 9, 10, 11 and the inlet / It is possible to prevent the water side hinges 16, 18 and the connectors 5, 6, 7, 8 from leaking when released.

In detail, a flange-shaped rib 30 formed on the left and right outer sides of the connectors 5, 6, 7, 8 is located inside the plate 12a of the fastening portion 12, and the hinge 9 And the supporter 31 formed on the bottom surface of the upper plate of the inlet and outlet side hinges 16 and 18 is positioned outside the plate 12a of the coupling portion 12. The ribs 30 and the supporter 31 wrap the inner and outer sides of the plate 12a so that the plates 12a of the fastening portions 12 are spaced apart from the hinges 9, The side hinges 16 and 18 can be prevented from being separated from each other.
