The mixed water flowing out of 26 is the plate 250b of the valve body 250a.
And flows out around the straight discharge flow path forming member 227, and is discharged from the shower discharge port 223 through the discharge surface upstream space 220 c formed by the partition member 225 and the shower plate 221.

Thus, the water purification cartridge 23
Even when the flow path switching valve 240 is provided on the downstream side of 0, both the raw water and the purified water can be easily selected. In combination with the discharge switching valve 250, both the raw water and the purified water are discharged straight. Or, it becomes possible to perform shower discharge. Further, at the time of discharging the raw water, the flow path on the upstream side of the water purification material 233 becomes a common flow path for the raw water and the purified water, and the water purification material 233 covered with the filter 234 is used.
The accumulated water that has accumulated on the surface of the filter 234 when the purified water is discharged is washed away by the mixed water passing through the inner surface side of the filter, making it difficult to cause clogging and preventing the water purification material 233 from deteriorating. Performance can be maintained at a high level.

It flows out around the discharge flow path forming member 327 and is discharged from the shower discharge port 323 via the discharge surface upstream space 320c formed by the partition member 325 and the shower plate 321.

As a result, the water purification cartridge 33
Even when the flow path switching valve 340 is provided on the downstream side of zero, both raw water and purified water can be easily selected. In combination with the discharge switching valve 350, both raw water and purified water are discharged straight. Or, it becomes possible to perform shower discharge. Furthermore, at the time of discharging the raw water, the flow path upstream of the water purification material 333 (the outer peripheral flow path 331 of the water purification cartridge 330) becomes a common flow path for the raw water and the purified water, and the water quality covered by the filter 334 is removed. Purifying material 333
The accumulated water that has accumulated on the surface of the filter 334 when the purified water is discharged is washed away by the mixed water passing through the outer surface side of the filter, making it difficult for clogging to occur and preventing the water purification material 333 from deteriorating. Performance can be maintained at a high level.
