た同時に連通することができる。An X-shaped ring 15 serving as a sealing material is provided on the outer periphery on the upper side of the cylindrical skirt.
Raw water that has flowed into the water supply hole 10b passes through the notch or opening 14b from the outer peripheral side of the cylindrical skirt portion, flows into the inner peripheral side of the cylindrical skirt portion, and is directed in the direction of arrow S, that is, on the water passage side of FIG. (In the direction of arrow B). Therefore, the state of FIG. 3 shows the discharge state of purified water.
At this time, since the lower end of the lower end 14a of the support shaft 14e of the cylindrical skirted valve stem 14 located on the middle and right sides shown in FIG. 3 is not in contact with the projection cam 11a of the rotary valve stem 11, the filter plate 13 and is urged downward by the pressure of the compression spring 18 and the flow of the raw water flowing in. For this reason, both the water supply holes 10b located at the middle and right sides of the water switch case 10 are both closed by the X-shaped ring 15, and both are connected to the raw water channel (the direction leading to the arrow F in FIG. 1). Raw water is in a water-stop state. When the water supply hole 10b located on the left side communicates with the purified water channel connected to the filtration cartridge 8 as described above, the water supply holes 10b located on the middle and right sides are stopped, and conversely, the water supply holes located on the middle and right sides. When the protrusions 11b communicate with each other by the contact of the projection cams 11a, the remaining water supply holes 10b remain closed.
In this way, the water supply hole 10b and the water channel groove 11c can be selectively and simultaneously communicated.

る。A D-shaped ring 15 'serving as a sealing material is provided on the outer periphery above the cross-shaped or Y-shaped rib. The raw water that has flowed into the water supply hole 10b flows into the fan-shaped recess 14'b from the outer periphery of the cross-shaped or Y-shaped rib, and is directed in the direction of arrow S, that is, on the side of the purified water channel (in the direction of arrow B in FIG. 1). ). Therefore, the state of FIG. 6 shows the discharge state of purified water. At this time, the valve stem 1 with a cross-shaped or Y-shaped rib located at the middle and right sides shown in FIG.
The lower end 14'a of the 4 'is provided with the projection cam 11a of the rotary valve rod 11.
Are not in contact with the filter plate 13 and are urged downward by the compression spring 18 mounted between the filter plate 13 and the water pressure of the flowing raw water. For this reason water switch case 1
Both of the water supply holes 10b located on the middle and right sides of the zero are closed by D-shaped rings 15 ', and both are connected to the raw water channel (the direction leading to the arrow F in FIG. 1). State. When the water supply hole 10b located on the left side communicates with the purified water channel connected to the filtration cartridge 8 as described above, the water supply holes 10b located on the middle and right sides are stopped, and conversely, the water supply holes located on the middle and right sides. When the protrusion 10b communicates with the projection cam 11a, the remaining water supply hole 10b
Remains closed. In this way, the water supply hole 10b
And the water channel 11c can be selectively and simultaneously communicated.
