Best Mode for Carrying Out the Invention Hereinafter, an example of using a water outlet valve for a water purifier having a raw water shutoff function according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

5, when the knob 22 is operated to be positioned on the first display unit 32, the purified water purified by the filter 4 is discharged to the outlet (not shown) 14). ≪ / RTI > That is, the raw water moving passage 16 is kept closed by the first check valve 17, and the constant movement passage 19 is kept closed by the second check valve 18.

Therefore, even when the raw water (raw water not purified by the filter 4) is discharged through the faucet 7 connected to the water pipe in the state where the discharge port 14 is closed, It is possible to prevent backflow from occurring because the passage 16 is blocked. Therefore, it is possible to solve the noise problem caused by the back flow.

When the knob 22 is rotated to the second display portion 33 at a first arbitrary angle (for example, at an angle of 90 degrees), the rotation of the shaft 20 causes the first check valve 17 and the second check valve The check valve 18 can be interlocked and rotated at the same angle.

The first pressing surface 24 of the first turning piece 26 and the first pressing surface 28 of the second turning piece 30 formed on the outer peripheral side of the shaft 20 and the lower portion thereof, 1 check valve 17 and the second check valve 18, so that the check function is canceled.

The raw water that is supplied from the raw water supply source through the pressure reducing valve 2 as a result of opening the raw water moving passage 16 and the purified water passage 19 is supplied to the raw water inlet of the first valve body 12 10).

The raw water flowing into the first valve body 12 through the raw water inlet 10 passes through the raw water moving passage 16 and the first check valve 17, the first turning piece 26, the raw water outlet 11, And is discharged from the first valve body 12.

The raw water discharged from the first valve body 12 flows into the filter 4 along the channel, and thus purified. At this time, since the structure for filtering the foreign substances contained in the raw water by the filter 4 is used in the related art, detailed description of these components is omitted.

Meanwhile, the purified water purified by the filter 4 flows into the second valve body 15 through the purified water inlet 13, so that the purified water in the purified water passage 19, the second check valve 18, Passes through the second rotating piece (30), passes through the second check valve (18), and is moved to the discharge port (14). Accordingly, the user can use the purified water discharged through the discharge port 14 of the second valve body 15.

When the knob 22 is rotated by the third display unit 34 at a second arbitrary angle (for example, at an angle of 155 degrees), the first check valve 17 and the second check valve 18 are interlocked It can be rotated at an angle.

That is, when the shaft 20 is rotated, the check function of the first check valve 17 is maintained by the second cut surface 25 of the first turning piece 26, 17 to shut off the raw water moving passage 16.

On the other hand, when the shaft 20 rotates, the second check valve 29 of the second rotating piece 30 presses the second check valve 18 to release the check function. This causes the water passage 20 to open.

Therefore, the first check valve 17 with the check function keeps shutting off the raw water flow passage 16, thereby preventing the raw water from flowing into the raw water inlet 10 of the first valve body 12 from the raw water supply source , While the filter (4) is replaced as the integral passage (19) is opened by the second check valve (18) with the check function being released, the outlet of the second valve body The residual pressure in the filter 4 can be discharged through the valve 14.

As described above, according to the embodiment of the present invention, a control valve for controlling the flow of raw water supplied from the raw water supply source, a control valve for controlling purified water flow purified by the filter 4, When the control valve 4 is replaced, the control valve for controlling the residual pressure flow discharged from the filter 4 is unified, so that the number of parts can be reduced and the cost cost can be greatly reduced. In addition, by opening and closing the first check valve 17 and the second check valve 18 by one-touch operation of the knob 22, convenience for the user can be provided.

The first check valve 17 also keeps the raw water passage 16 closed when the water passage 19 is closed by the second check valve 21. As a result, Even when the faucet 7 is opened in a state where the discharge port 14 is closed, the raw water flow passage 16 is blocked, so that reverse flow can be prevented. Therefore, it is possible to prevent noise from occurring due to backflow.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims. And changes may be made without departing from the spirit and scope of the invention.
