Heads (not shown) are connected to each other.

The operation of the faucet device 1 configured as described above will be described.
First, when the mixing unit 2 and the switching unit 18 of the faucet device 1 are mounted inside the mounting wall A such as a counter, the direction of the pipe connecting members 11 and 11a depends on the positional relationship between the installation location and the pipe. It is determined by rotating around the central axes L1 and L2.

  That is, the pipe connection member 11 is rotated on the mixing unit 2 side. In this state, if the water supply pipe 16 is connected to the first connection port 13 and the hot water supply pipe 17 is connected to the second connection port 14, the water supply pipe 16 and the hot water supply pipe 17 are bent or bent. It is possible to connect them linearly or in a state close to a straight line.

  Similarly, on the switching unit 18 side, the pipe connection member 11a is rotated, and in this state, the currant side connection pipe 28 is connected to the first connection port 13a and the shower side connection to the second connection port 14a. If the pipes 29 are connected to each other, they can be connected in a straight line or a state close to a straight line without curving or bending the currant side connecting pipe 28 and the shower side connecting pipe 29.

  That is, the pipe connecting member 11 is rotatable around the central axis L1 of the outer case 3 of the mixing unit 2, and the pipe connecting member 11a is rotatable around the central axis L2 of the outer case 19 of the switching unit 18. Each of the connection ports 13, 14, 13a, 14a of the connection members 11, 11a can be oriented in either the left or right direction. Therefore, the water supply pipe 16, the hot water supply pipe 17, the currant side connection pipe 28, and the shower side connection pipe 29 are bent at any position except when avoiding interference with the mixing unit 2 and the switching unit 18. It can be connected to the connection ports 13, 14, 13a, 14a without bending.

  When the faucet device 1 is used, the switching unit 18 is operated in a state where the mixing ratio of water and hot water (temperature of the mixed water) is arbitrarily set by rotating the temperature adjusting handle 6 of the mixing unit 2. The flow path switching handle 22 is turned to the currant side or the shower side. Then, the water and hot water supplied into the mixing unit 2 from the water supply pipe 16 and the hot water supply pipe 17 via the connection ports 13 and 14 of the mixing unit 2 are mixed or mixed at a set mixing ratio. Without being supplied to the switching unit 18 via the connection pipe 30.

  Further, in the switching unit 18, the flow path of the water, hot water or mixed water supplied from the mixing unit 2 is switched to the currant side or the shower side by the turning operation of the flow path switching handle 22, and the water, hot water or mixed water is switched. Is supplied to the shower side connecting pipe 29 via the first connecting port 13a and the currant side connecting pipe 28 or the second connecting port 14a. As a result, water, hot water or mixed water set to a predetermined temperature by the temperature adjustment handle 6 and set to a predetermined water discharge amount by the amount of rotation of the flow path switching handle 22 is discharged from the currant or shower head.

In this embodiment, the pipe connection member on the mixing unit side is provided with connection ports on the left and right sides, and the pipe connection member on the switching unit side is described on an example in which the connection port is formed on the same axis with the attachment portion interposed therebetween. However, the present invention is not limited to this. For example, the pipe connection member on the mixing unit side has the connection port formed on the same axis with the attachment portion interposed therebetween, and the pipe connection member on the switching unit side has the connection port on the left and right sides. A pipe connecting member having the same structure may be attached to both units. The connection port is formed perpendicular to the axial direction of the mounting portion, that is, the central axis direction, but is not limited to this, and is parallel to the axial direction of the mounting portion, that is, the central axis direction. It may be formed.

Therefore, according to the present embodiment, the following effects can be obtained.
The faucet device 1 is equipped with a mixing unit 2 that adjusts the mixing ratio of water and hot water, and a switching unit 18 that switches the flow path of the mixed water adjusted by the mixing unit 2. Valve mechanisms 4 and 20 are accommodated in the outer cases 3 and 19 of the units 2 and 18. On the outer periphery of each outer case 3, 19, pipe connection members 11, 11 a that can communicate with the valve mechanisms 4, 20 are attached so as to be rotatable about the central axes L 1, L 2 of the outer cases 3, 19. .

  For this reason, if the central axes L1 and L2 of the mixing unit 2 and the switching unit 18 are set to be horizontal or substantially horizontal, the pipe connection members 11 and 11a are arranged according to the positional relationship between the installation location of the faucet device 1 and the pipe. The connection direction can be directed in any direction. Therefore, the water supply pipe 16 and the like can be straightly piped along the predetermined direction with respect to the pipe connecting members 11 and 11a, and the pipe connecting work can be easily and quickly performed. Further, since the pipe is hardly bent or bent, the risk of pressure loss can be suppressed, and the mixed water or the like can be smoothly supplied to the user.

  Further, in the faucet device 1, the pipe connection members 11 and 11a of the units 2 and 18 are configured to be able to rotate 360 degrees around the horizontal central axes L1 and L2. For this reason, each piping connection member 11 and 11a can be rotated to the left or right direction around the outer cases 3 and 18, and the connection direction of these piping connection members 11 and 11a is matched with a piping direction. It can be changed freely without any blind spots.

  Furthermore, in this faucet device 1, the connection ports 13, 14, 13a, 14a of both the units 2, 18 are formed integrally with the pipe connection members 11, 11a. For this reason, since the number of parts of the faucet device 1 can be reduced, the manufacturing cost can be reduced, and the faucet device can be easily assembled.
