As with 25, it is assembled so as to rotate around the central axis. And the vicinity of the through-hole formation part of the switching valve main body 20 is covered with the main body cover top 16 so that the through-hole 20b formed in the side surface of the switching valve main body 20 may not be exposed when the lever handle 26 is operated.

  The lower end of the switching valve body 20 and the lower case 21 are connected to a raw water inflow path 31 through which the primary side raw water flows and a water purifier 40 through the central cavity of the main body adapter 13 and the hole of the top plate mounting unit 19. The raw water outflow passage 32 (see FIG. 4) that communicates with the raw water inlet 40c and passes the primary raw water, the purified water passage 33 that communicates with the purified water outlet 40a of the water purifier 40, and the raw water outlet 40b of the water purifier 40 communicate with each other. A raw water flow path 34 (see FIG. 4) is formed.

The fixed valve 23 and the movable valve 24 that form the valve seat and the valve body of the switching valve are formed in a thick disk provided with necessary recesses or through holes.
As shown in FIG. 5, the fixed valve 23 has rectangular cut portions 23 a, 23 a, in which two wide rectangles and two narrow rectangles are arranged side by side at four locations on the outer circumferential surface. 23b, 23b are engraved, and the holes 23c, 23d, 23e, 23f are formed at the same distance from the center (axial center) with the plane shape formed in a fan shape and penetrating with substantially the same flow area from the upper surface to the lower surface. Two holes are drilled side by side at two positions (on the same circumference) and axisymmetric. As for the size of each hole, the holes 23c and 23d are formed in the same size, the holes 23e and 23f are formed in the same size, and the latter is larger in the holes 23c and 23d and the holes 23e and 23f. Form.
The holes 23c, 23d, 23e, and 23f of the fixed valve 23 are used as a purified water flow path, a raw water flow path, a raw water inflow path on the upstream side of the water purifier, and a raw water outflow path, respectively.

  As shown in FIG. 6, the movable valve 24 is formed by engraving rectangular recesses 24 a at four locations on the outer circumferential surface, and forming a circular recess 24 b with a certain depth on the upper surface. A through hole 24e is formed by combining two large and small fan-shaped holes 24c and 24d having a common center line of the curved portion from the circular recess 24b. The through hole 24e has a large fan-shaped hole 24c drilled from the downstream side and a small fan-shaped hole 24d drilled from the upstream side, and the position is adjusted so that both the holes 24c and 24d intersect and penetrate at an intermediate position. . Further, on the upstream surface, in addition to the small fan-shaped hole 24d, the small fan-shaped hole 24d and a fan-shaped hole having a size covering both the two holes 23e and 23f of the fixed valve 23 at the axially symmetrical position are formed. The communication path 24f formed is engraved so that the flow path through which the primary-side raw water flows is diverted from the hole 23e by the communication path 24f and flows out to the water purifier side through the hole 23f. To do.

The movable valve 24 and the fixed valve 23 can be combined with each other according to their relative positions when combined, and a necessary flow path is formed.
As shown in FIG. 4, when the movable valve 24 is rotated and the holes 24 c and 24 d forming the through hole 24 e of the movable valve 24 overlap with one of the holes 23 c and 23 d of the fixed valve 23, the water purifier The flow path on the downstream side can pass water, and either purified water or raw water can be discharged.
At this time, the communication path 24f (see FIG. 5) is positioned at the position of the movable valve 24 facing the holes 23e and 23f of the fixed valve 23, and the holes 23e and 23f of the fixed valve 23 are communicated with each other. From the hole 23e through the communication passage 24f to the hole 23f, and flows from the hole 23f through the raw water outflow passage 32 into the water purifier 40 through the raw water inlet 40c.
As a result, the raw water flowing into the faucet part 11 from the raw water inflow passage 31 connects the two holes 23e and 23f of the fixed valve 23 via the communication passage 24f of the movable valve 24, changes the direction of the flow path, and flows out of the raw water. Raw water can flow into the water purifier 40 through the path 32 and the raw water inlet 40c.

In the water purifier 30 provided with this composite faucet 10, the order of raw water discharge and purified water discharge from the time of water stoppage is set by the piping between the faucet part 11 and the built-in water purifier 40.
For example, as shown in FIG. 7, the lever handle 26 is turned from the time of water stoppage (see FIG. 8), and first the raw water is discharged (see FIG. 9), and then the purified water is discharged (see FIG. 10). In the case of setting the order, as shown in FIG. 4, the raw water outflow path 32 is connected to the raw water inlet 40 c of the water purifier 40, the purified water flow path 33 is connected to the purified water outlet 40 a of the water purifier 40, The water channel 34 is piped so as to be connected to the raw water outlet 40 b of the water purifier 40.
As a result, when the lever handle 26 is turned to the discharge side with the water stop state as a base point, the holes 24c and 24d that form the through holes 24e of the movable valve 24 become holes 23d of the fixed valve 23 as shown in FIGS. The downstream raw water flow path 34 communicating with the raw water outlet 40b of the water purifier 40 is allowed to flow, and the fan-shaped communication path 24f of the movable valve 24 is formed in the holes 23e and 23f of the fixed valve 23. Positioned above, the hole 23e and the hole 23f are communicated with each other through the communication passage 24f, and the primary side raw water flows into the water purifier 40 through the faucet part 11, and passes through in an unpurified state. It flows out to the faucet part 11 side via the raw | natural water flow path 34, and can discharge now with raw | natural water.

  Thereafter, when the lever handle 26 is further rotated in the same direction, as shown in FIGS. 4 and 10, the holes 24 c and 24 d forming the through holes 24 e of the movable valve 24 reach positions where the holes 23 c of the fixed valve 23 overlap. The downstream purified water flow path 33 communicating with the purified water outlet 40 a of the water purifier 40 can pass through the water, and at the same time, the fan-shaped communication path 24 f of the movable valve 24 is positioned above the holes 23 e and 23 f of the fixed valve 23. And the state where the hole 23e and the hole 23f are communicated with each other through the communication path 24f is maintained, and the primary raw water flows into the water purifier 40 through the faucet portion 11, and is purified by the water purifier 40. Then, it flows out to the faucet part 11 side through the purified water flow path 33, and it becomes possible to discharge purified water.

As shown in FIG. 4, the water purifier 40 incorporating the purification material-containing cartridge 43 for water purification includes one raw water inlet 40c and two outlets, namely, a purified water outlet 40a and a raw water outlet 40b. Then, from the raw water inlet 40c to the location where the upstream surface of the cartridge 43 containing the purification material forms a part of the flow path is defined as an upstream flow path 40e, and the quality of the water path from the upstream water flow path 40e to the raw water outlet 40b is improved. A raw water flow path 41 inside the water purifier that is not purified is formed, and a path from the upstream flow path 40 e of the raw water flow path 41 through the purification material-containing cartridge 43 to the purified water outlet 40 a is formed as the purified water flow path 42.
Thereby, in the case of water purification discharge, the water quality is purified in the process of the raw water passing through the cartridge 43 containing the purification material inside the water purifier, and in the case of raw water discharge, the purification water is contained when the raw water passes through the raw water flow channel 41. Contaminants attached or deposited on the surface of the cartridge 43 are washed away.

[Function and effect]
In the embodiment configured as described above, when the lever handle 26 is in the water stop position (FIG. 7), as shown in FIG. 8, the lever handle 26 rotates integrally with the rotation shaft member 25 to which the lever handle 26 is attached. The relative positional relationship between the movable valve 24 assembled to the fixed valve 23 and the fixed valve 23 with which the movable valve 24 comes into surface contact is such that the through hole 24e (hole 24d) of the movable valve 24 is connected to the hole 23d and the hole 23e of the fixed valve 23. The discharge-side flow passages 33 and 34 are closed at a non-perforated portion between them, and the fan-shaped communication passage 24f of the movable valve 24 is positioned so as to straddle both the hole 23c and the hole 23f of the fixed valve 23. Thus, the raw water inflow passage 31 connected to the primary side raw water is closed, and both the inflow and discharge flow paths 31, 32, 33, and 34 of the faucet portion 11 are closed, and water cannot pass through. At this time, since the communication path 24f of the movable valve 24 is located across both the hole 23c and the hole 23f of the fixed valve 23, the raw water in the raw water outflow path and the purified water in the purified water flow path are mixed. Thus, only the purified water is not sealed, and it is possible to prevent germs from breeding in the closed flow path located upstream of the movable valve 24 of the faucet part 11 due to the chlorine content in the raw water.

When the lever handle 26 is rotated to change from the water stop position to the raw water discharge position (FIG. 7), the position of the through hole 24e (hole 24d) of the movable valve 24 is changed to the hole 23d of the fixed valve 23 as shown in FIG. The raw water flow path 34 and the water flow path 25a of the rotary shaft member 25 are communicated to change the flow path on the discharge side to the raw water discharge, and the communication path 24f of the movable valve 24 is a fixed valve 23.
