<P>PROBLEM TO BE SOLVED: To provide an automatic water supply device capable of reducing an error in a total amount of discharged water to a toilet bowl due to variance in water supply pressure and a momentary flow rate. <P>SOLUTION: An automatic water supply device includes a solenoid valve 16 provided to a water conduction channel 8d of an automatic water supply device body 4 to be opened and closed, and a controller 22 which adjusts a solenoid valve opening time T1 based upon water flow information detected by a flow rate sensor 20 detecting the water flow information on the water condition channel of the automatic water supply device body so as to control toilet bowl washing. Based upon the water flow information that the flow rate sensor 20 detects in a predetermined period Δt in the period from valve opening operation start time t1 of the solenoid valve 16 to valve closing operation start time t3, the controller 22 adjusts the time t3 when the valve closing operation of the solenoid valve 16 starts so that the total amount of water discharged from a water discharge port 10 to the toilet bowl reaches a predetermined water discharge amount while taking into consideration an amount of closing discharged water flowing out of the water discharge port 10 from when the solenoid valve 16 starts the valve closing operation until when a main valve body 14 is closed. When the adjusted period comes, the valve closing operation of the solenoid valve 16 is started. <P>COPYRIGHT: (C)2013,JPO&INPIT |
