The zero solenoid 204 is excited. Solenoid 204
Due to the excitation, the plunger 206 and the valve body 205 are integrally separated from the valve seat 224 against the spring 208. The water in the water side back pressure chamber 66 and the hot water in the hot water back pressure chamber 166 are discharged to the outside through the discharge flow path 222 as waste water. At this time, the drainage flow rate of the discharge flow path 222 is the flow rate flowing from the primary side flow path 32 into the water side back pressure chamber 66 via the communication path 76 and the drain flow rate from the primary side flow path 132 via the communication path 176. Since it is larger than the sum of the flow rate flowing into the pressure chamber 166,
The liquid pressures in the water side back pressure chamber 66 and the hot water side back pressure chamber 166 respectively decrease. Due to the decrease in the hydraulic pressure, the valve body 70 and the valve body 170 are opened, water flows from the primary side flow passage 32 to the secondary side flow passage 42 through the flow passage opening 28, and the primary side flow is generated. Hot water flows from the passage 132 through the passage opening 128 to the secondary passage 142.
