As shown in the figure, an annular groove 27 is provided around the inlet 26 of the third flow path, and a valve seal packing 31 is attached thereto. Further, a semicircular recess 29 is formed at the small diameter end of the valve body 21, and a stopper 3 is provided at the deep bottom of the valve body mounting port 1a shown in FIG.
3 to prevent the valve body 21 from rotating more than necessary.

The reference numeral 34 shown in FIG. 1 is a click ring that provides a click feeling when the lever 32 is rotated to select one of the three channels formed in the valve body 21. The valve body 21 is also configured to come into contact with the inner surface of the cover 35 described in 1. to prevent the valve body 21 from coming off in the opposite direction to the mounting direction due to water pressure. 35 is the valve body mounting port 1a of the valve box 1
This is a cover that screws into the threaded part provided on the outer edge of the inlet.

The water purifier main body 18 is connected to the third outlet 5 of the valve box 1.
It is a hollow container that communicates with the purified water outlet 19 and has a purified water outlet 19 at the bottom, and a filter cylinder 18a is housed inside the hollow container, and the outflow side thereof is formed to communicate with the purified water outlet 19.

Next, the operation of the water purifier having the above configuration will be explained using FIGS. 1 to 3.

FIG. 1 shows a state in which the first flow path 23 of the valve body 21 is selected. In this case, the inlet 2 of the valve body 1 communicates with the first outlet 3 via the first flow path 23 .
Therefore, the raw water from the faucet 20 flows out from the first outlet 3, is rectified by the rectifying plate 15, and then is discharged as straight drainage. At this time, valve body 2
1 and the inlet 26 of the third flow path are sealed by the valve stem seal packing 30 and the valve seal packing 31, so that the raw water is prevented from leaking to the third outlet 5 and the outside. There is a concern that leakage may occur through the gap between the valve box 1 and the valve body 21 to the second outlet 4. However, the first
The inlet of the flow path 23 has a larger diameter, and the first flow path 2
The diameter of the first outlet 3 of the valve body 1 is larger than that of the outlet 3, and there is no bend from the inlet 2 to the first outlet 3, so the flow velocity is high and pressure loss is small. No leakage to outlet 4. Therefore, seal packings are not required at the inlet and outlet of the first flow path 23.

FIG. 2 shows the state in which the lever is rotated 90 degrees to the left when viewed from the lever 32 side compared to the state shown in FIG.
5 is selected. In this case, the inlet 2 of the valve body 1 communicates with the second outlet 4 via the second flow path 25 . Therefore, the raw water from the faucet 20 is
The water flows out from the outlet 4, is rectified by the shower-side rectifying plate 17, and is discharged as an even shower.
At this time, both ends of the valve body 21 and the inlet 26 of the third flow path
is sealed by the valve stem seal packing 30 and the valve seal packing 31, so that the raw water does not leak to the third outlet 5 and the outside. At the same time, the valve seal gasket 31 also seals the first outlet 3, so that no leakage occurs to the first outlet 3.

Figure 3 shows the third flow path 2 by rotating the lever 90 degrees to the right when viewed from the lever 32 side than in the state shown in Figure 1.
8 is selected. In this case, the inlet 2 of the valve body 1 communicates with the third outlet 5 via the third flow path 28 . Therefore, the raw water from the faucet 20 is
After flowing into the gap between the water purifier main body 18 and the filter cylinder 18a from the outlet 5, the water is purified through the inside of the filter cylinder 18a, and is discharged from the purified water drain port 19. At this time, since the inlet 26 of the third flow path 28 is sealed by the valve seal packing 31, there is no leakage to other flow paths.

(Effects of the Invention) As is clear from the above description, according to the present invention, by operating one lever, it is possible to easily select among the straight drainage of raw water, purified water, and showering of raw water.

In addition, if configured as in the above embodiment, the seal gasket will consist of one valve seal gasket provided on the inlet side of one of the three flow paths and two shaft seal gaskets provided on the valve body. With only 3 pieces, leakage can be completely prevented with just a few seals.

Furthermore, there is only one valve seal gasket that communicates the mouth edges of each inlet and outlet of the valve box, which allows the valve body to rotate smoothly.
There is less damage to the seal packing, resulting in a longer life.
