By the way, in the conventional switching valve, the water passage 2, the tubular portion 3, the straight outlet 9, the shower outlet 10, the shower cap, etc. are vertically arranged. Therefore, the height dimension inevitably becomes large, and it is difficult to further reduce the height. Therefore, when the switching valve is attached to the faucet, the space between the lower end of the switching valve and the bottom of the sink becomes very narrow, and the working space below the switching valve cannot be sufficiently secured, and cooking and washing of dishes are not performed. There was a problem that it was difficult to do such work. In addition, the switching valve includes the opening 5 of the tubular portion 3.
And the outflow port 9 of the valve body 1 and the opening 6 and the outflow port 10 are made to coincide with each other so that the water flows out to the target outflow port. Therefore, the openings 5, 6 and the outflow ports 9, 1
In order to secure a sufficient amount of runoff water to 0,
Since the cylindrical portion 3 and the valve body 1 need to have a sufficient circumferential dimension, they are increased in size and the above problem becomes more serious.

On the other hand, when connecting the water purifier to the switching valve, the opening of the tubular portion 3 and the outlet of the valve main body 1 are added, and the water purifier is connected to the added outflow passage. In particular, the size of 1 in the direction along the cylindrical body 3 becomes large, and this causes a problem that the lower portion of the switching valve becomes difficult to see.
Further, the water purifier is directly fixed to the side portion of the valve body 1 or is installed in a different place from the switching valve, but in the former case, there is a problem that the lower portion of the switching valve becomes more difficult to see,
In the latter case, since purified water is discharged from the outlet of the water purifier, there arises a problem that the outlets 9 and 10 are likely to be mistaken for the water outlet location. In addition, although the outlet of the water purifier is provided separately from the outlets 9 and 10, a space for installing the outlet and a working space below the outlet when using purified water are required. Therefore, these spaces can be secured in a narrow sink. There is also a problem that it becomes difficult and causes a decrease in workability such as cooking and washing dishes.
