If the foot switch is turned off before the foot switch on time has elapsed a predetermined time (for example, 3 seconds) after controlling the open state of the sole valve, as a touch control process, it is determined whether the foot switch is on. Return to step S1.

On the other hand, if the foot switch is not turned on in the step (S1) of determining whether the foot switch is on, the step (S8) to determine whether the sole valve 20 is open, the sole valve is not open If not, return to step S1 to determine whether the footswitch is on. If the solenoid valve is open when the footswitch is off, the time for which the solenoid valve is open is a fixed time (e.g., 3 minutes). ) Performs the automatic water supply stop time determination step (S9) to determine whether elapsed. If 3 minutes have not elapsed in the automatic water supply stop time determination step (S9), return to the foot switch on signal determination step (S1), and if 3 minutes have elapsed, controlling the solenoid valve in a closed state (S3) is performed. do.

That is, when water is started by pressing the footswitch for less than 3 seconds for the first time during the exaggeration of the touch control, the water supply is automatically stopped after 3 minutes when the water supply is left without pressing the footswitch again.

Therefore, the pressing control process of the present invention, the foot switch on determination step (S1), the sole valve reading determination step (S2), the control step (S4), the predetermined time elapsed determination step (S5), the sole valve open state, the sole valve The water supply state is maintained through the open state maintaining step (S ^), and when the foot switch is turned off by releasing the foot switch, controlling the state of the solenoid valve through the foot switch off determination step (S7) (S3). Press to terminate the press control process.

In addition, the touch control process, the foot switch on determination step (S1), the sole valve reading determination step (S2), the control step (S4), the predetermined time elapsed determination step (S5) to the sole valve open state, at this time When the switch is turned off within 3 seconds, the water supply is maintained in the off state of the foot switch, and when the foot switch is turned on again through the foot switch on determination step (S1) while the water supply is maintained, the sole valve opening state determination step The touch control process is terminated by performing the step S3 of controlling the state of the sole valve through the S2.

In addition, the automatic water supply stop control process, the sole valve when the foot switch is not turned on in the foot switch on determination step (S1) performed for the second time during the touch control process to control the sole valve to the open state. Determining whether is open (S8), the step of determining whether the sole valve is open for a predetermined time (S9), if there is no second footswitch on signal for a predetermined time, the sole valve control state (S2) End the automatic water supply stop control process by executing.

As described in detail above, the water-saving device according to the present invention accommodates a solenoid valve, a control board, and a battery in one housing, and provides it as one device, and provides only a foot switch to be installed externally.
