(Background to the present invention)
A faucet that mixes hot water and water supplied from a hot water supply port and a water supply port and discharges water from a shower or a faucet is known. For example, in the faucet of Patent Document 1, hot water and water are mixed by a hot water mixing valve of a water passage portion housed in a metal pipe, and the amount of mixed water discharged and the direction of water discharge are controlled by a switching valve.

In the faucet of Patent Document 1, the hot water inlet (hot water joint) into which hot water flows from the hot water supply port and the water inlet (water supply joint) into which water from the water supply port flows in are separated from each other in a metal pipe. ing. Further, in the water passage, the metal pipe is provided with a mixed water outlet through which the mixed water in which hot water and water are mixed flows out. In the faucet of Patent Document 1, a hot water inlet, a mixed water outlet, and a water inlet are provided in this order from one side to the other side of the metal pipe.

In the faucet of Patent Document 1, the inflowing hot water and water are supplied to the hot water mixing valve through the flow path formed in the water passage portion. Further, due to the structure of the hot water mixing valve, it is necessary to bring hot water and water close to each other to supply the hot water mixing valve. The mixed water mixed in the hot and cold water mixing valve is discharged from the shower or the curan by flowing out from the mixed water outlet through the flow path and the switching valve formed in the water passage portion.

On the mounting surface to which such a faucet is attached, a hot water supply port and a water supply port are often provided corresponding to the positions of the hot water inlet and the water inlet provided in the metal pipe.

The present inventors have developed a faucet made of resin in order to realize a reduction in manufacturing cost.

In the faucet, the hot water inlet and the water inlet are provided close to each other on one side where the hot water mixing valve is arranged, and the mixed water outlet is provided on the other side where the switching valve is arranged. ..

However, like the faucet of Patent Document 1, many faucets are provided with the hot water inlet and the water inlet separated from each other. Further, the hot water supply port and the water supply port provided on the mounting surface side such as the wall surface of the bathroom are provided apart from each other in order to correspond to the positions of the hot water inlet and the water inlet of the faucet. That is, the distance between the hot water inlet and the water inlet of the faucet is equal to the distance between the hot water supply port and the water supply port on the mounting surface side. In addition, the distance between the hot water supply port and the water supply port is often standardized.

In such a case, when the resin faucet invented by the present inventors is attached to the attachment surface corresponding to the conventional faucet, the distance between the hot water supply port and the water supply port on the attachment surface side is reduced. There is a need. Therefore, the resin faucet cannot be easily attached to the attachment surface.

As a result of diligent research, the present inventors have conducted a hot water supply port and a water supply port on the mounting surface side, and a hot water channel connecting the hot water inlet and the water inlet of the faucet main body of the resin faucet, respectively. We have found a configuration in which a resin faucet is attached to a mounting surface using a flow path block having a water channel, and have reached the following invention.

Hereinafter, embodiments will be described with reference to the accompanying drawings. Further, in each figure, each element is exaggerated for the sake of easy explanation.

Since the water channel 82 three-dimensionally intersects the mixed water channel 83, the water flowing through the water channel 82 also flows in a direction that three-dimensionally intersects the direction of the mixed water flowing through the mixed water channel 83. Specifically, the water flowing into the flow path block 80 from the water channel upstream port 82a flows under the mixed water channel 83 in the width direction (Y direction) of the flow path block 80. After that, the water flows in the thickness direction (X direction) of the flow path block 80, and flows into the faucet main body 21 from the water channel downstream port 82b. The mixed water flowing inside the faucet main body 21 flows into the mixed water channel 83 from the mixed water channel upstream port 83a of the flow path block 80, and is discharged from the mixed water channel downstream port 83b (see arrow F3). The mixed water flowing into the flow path block 80 from the mixing water channel upstream port 83a flows above the water channel 82 in the width direction (Y direction) of the flow path block 80. After that, the mixed water flows in the thickness direction (X direction) of the flow path block 80, and flows into the shower elbow 29 from the mixed water channel downstream port 83b.
