FIG. 11 is a plan sectional view showing the inside of the faucet body in a water discharge state of the purified water similarly.

First, an outline of the composite single faucet of the present invention will be described with reference to FIGS. A composite single faucet 2 configured to discharge raw water and purified water is attached to a countertop 1 of a kitchen or the like. The composite single faucet 2 selectively discharges one of raw water and purified water from a spout 2d through a spout pipe 2c by rotating a switching operation lever 2b provided on the faucet main body 2a. It is configured as follows. In the composite single faucet 2, the lower end of the composite single faucet 2
A raw water conduit 3 for supplying raw water and a purified water conduit 4 for supplying purified water are fitted in the lower end of the raw water conduit 3 through a check valve 6 and a water stopcock 5a. And the water pipe 7
Is connected. The connecting portion between the water supply pipe 7 and the raw water conduit 3 is branched and connected to the inlet 6a of the water purifier 6 via the water stopcock 5b on the water purification side, and the outlet 6b of the water purifier 6 is connected to the water purifier 6 for water purification. It is connected to the lower end of the water pipe 4.

[0009] Tap water as raw water supplied from the water supply pipe 7 is directly sent out to the composite single faucet 2 through the raw water conduit 3, and at the inlet of the water purifier 6 connected to the water supply pipe 7. Water is supplied to the water purifier 6 from 6a. Water purifier 6
Is supplied to the composite single faucet 2 through the water purification pipe 4 after being purified by the water purifier 6. As described above, the tap water as raw water and the purified water obtained by purifying the tap water with the water purifier 6 are supplied to the composite single faucet 2 and the switching operation lever 2b is rotated to operate any one of the raw water and the purified water. One of them is selectively discharged from the water discharge port 2d. In addition, tap water as raw water supplied to the composite single faucet 2 through the raw water conduit 3 is discharged from the water discharge port 2d as water when supplied directly from the water pipe, and is supplied by a water heater or the like on the way. When heated and supplied, it is discharged from the water outlet 2d as hot water.

Next, a description will be given of a switching mechanism for switching the discharge of raw water, the discharge of purified water, and the stoppage of water of the composite single faucet 2. As shown in FIGS. 3 and 4, the raw water conduit 3 fitted into the composite single faucet 2 from the lower end is connected to a raw water flow path 11 in the faucet main body 2a. It is connected to the channel 12. The raw water flow path 11 has a communication hole 11
a is opened, and a communication port 12 a is opened in the purified water flow path 12. Further, a switching valve 15 is provided in the faucet main body 2a, and a switching valve shaft 15c of the switching valve 15 is configured to be rotated integrally with the switching operation lever 2b. The switching valve shaft 15c has a switching flow path 15a in the axial direction.
A switching communication port 15b for communicating the switching channel 15a with the outer peripheral surface of the switching valve shaft 15c is opened at one end of the switching channel 15a, and the other end of the switching channel 15a is provided with water. It is always in communication with the discharge channel 13 formed in the plug body 2a. Water spout pipe 2c fitted from the upper end of faucet body 2a
Is connected to the discharge channel 13.

The communication port 11a of the raw water flow path 11 communicates with the switching communication port 15b of the switching flow path 15a by the rotation position of the switching valve shaft 15c of the switching valve 15 which is rotated by the switching operation lever 2b. State (state shown in FIG. 5),
A state in which the communication port 12a of the purified water channel 12 communicates with the switching communication port 15b of the switching channel 15a, and the switching communication port 15b of the switching channel 15a is connected to the communication port 11a of the raw water channel 11 and the communication port 11a of the purified water channel 12. It is configured to be selectively switched to any one of the states that are not in communication with either of the communication ports 12a (the states shown in FIGS. 3 and 4).

The communication port 11a of the raw water flow path 11 and the switching flow path 1
When the raw water from the raw water conduit 3 is in communication with the switching communication port 15b of the raw water flow path 5a, the raw water flow path 11, the switching flow path 15
a, and is guided to the water discharge pipe 2c through the discharge flow path 13 and discharged from the water discharge port 2d, so that the composite single faucet 2 is in a water discharge state of raw water. In addition, the communication port 12a of the purified water flow path 12
And the switching communication port 15b of the switching flow path 15a, the purified water from the water purification conduit 4 passes through the purified water flow path 12, the switching flow path 15a, and the discharge flow path 13 to the water discharge pipe 2c. Guided and discharged from spout 2d, composite single faucet 2
Is in the state of spouting clean water. Further, in a state where the switching communication port 15b of the switching channel 15a is not in communication with either the communication port 11a of the raw water channel 11 and the communication port 12a of the purified water channel 12, the communication port 11a of the raw water channel 11 is switched. Since the raw water is blocked by the valve 15, the raw water from the raw water conduit 3 does not flow downstream of the raw water flow path 11, and the communication port 12 a of the purified water flow path 12 is closed by the switching valve 15. Therefore, the purified water from the water purification conduit 4 does not flow downstream of the purified water flow path 12, so that the composite single faucet 2 is in a water-stop state.

As described above, only by operating a single switching device constituted by the switching valve 15 and the switching operation lever 2b,
The composite single faucet 2 can switch between spouting of raw water, spouting of purified water, and stopping of water. Thereby, the switching operation between the water discharge and the water stoppage and the switching operation between the raw water discharge and the purified water discharge can be performed at the same time, and the switching operation can be simplified and the erroneous operation can be prevented.

The switching flow path 15a of the switching valve 15
The discharge passage 13 and the water discharge pipe 2c function as a raw water passage when the raw water from the raw water conduit 3 is discharged from the water discharge port 2d, and supply the purified water from the water purification conduit 4 to the water discharge port 2d. When it is discharged from, it functions as a water passage for purified water. That is, on the downstream side of the switching valve 15, the water passage for the raw water and the water passage for the purified water are shared.

As described above, by sharing the raw water passage and the purified water passage, for example, after discharging the purified water from the water discharge port 2d, the tap water as the raw water is discharged to switch the water passage. Purified water remaining inside the flow path 15a, the discharge flow path 13, and the water discharge pipe 2c can be washed with tap water, and bacteria can be removed downstream of the switching device inside the water passage through which the purified water passes. This can be prevented from occurring.

That is, since the residual chlorine contained in the tap water is removed from the purified water supplied from the water purifier 6, the purified water is discharged from the water discharge port 2d.
If the purified water remaining inside the water passage stays for a long time, various bacteria may be generated. However, since the tap water from the raw water conduit 3 contains residual chlorine, if the tap water is discharged after cleaning the clean water to wash the inside of the water passage,
The sterilization by the residual chlorine in the tap water can prevent the generation of various bacteria inside the water passage. Generally, composite single faucet 2
The frequency of tap water discharge is low, and the tap water is frequently discharged.If used normally, the tap water will be discharged within a short period of time after the discharge of purified water, reducing the occurrence of various bacteria. The inside of the canal can be kept sanitary.
