Therefore, when the control valve 3 is opened, the residual cold water in the mixing water chamber 41 and the residual cold water in the water outlet pipe 42 are simultaneously discharged from the water discharge sections 12 and 22 of the valve front cold water passage and the valve rear cold water passage, respectively. . The two drainage processes are independent of each other. Therefore, no matter which residual water in the waterway is discharged first, the residual cold water in the other waterway can continue to be discharged without being affected, reaching the main control valve 4.
