Body (41) from treated water delivery pipe (5) through communication pipe (414X)
It reaches the lower chamber (41B) of the lower chamber and is sent from here to the water discharge head (24) through the water discharge pipe (23). As a result, the treated water is discharged from the water discharge port (240) of the water discharge head (24). To discharge treated water, slide the changeover switch (67) to the tip side, that is, to the side of discharging raw water, or the lever (212) of the faucet body (21).
It can be stopped by performing a water stop operation.

As described above, also in the raw water / treated water switching / discharging device of the second embodiment, the raw water and the treated water can be discharged by operating the changeover switch (67) provided on the water discharge head (24). You can switch. Therefore, even when the water discharge head (24) is being used by pulling it from the faucet body (21), switching between raw water discharge and treated water discharge can be performed using the fingers of the hand holding the water discharge head (24). It's easy to do and very easy to use. Further, since the drive part (60A) of the raw water / treated water switching valve (60) is provided on the joint member (40) which is hidden below the top plate (B) apart from the faucet body (21). As the faucet body (21), it is possible to use a compact one that looks good.
