It will be described how to discharge the purified water in the section up to 150 (or where the third valve is located).

First, a user or a manufacturer inputs an operating time and a period of the purified water discharge operation and an operating time and a period of the purified water filling operation through the input unit 250.

The input time and periods are recorded in the timer 192 of the controller 190, and the discharge operation starts when the purified water discharge operation time or the purified water discharge operation time is compared with the present time to match the purified water discharge operation time. The signal is transmitted, and when the integer filling operation time matches, the integer filling start signal is transmitted.

After transmitting the signals, when the elapsed time after transmitting the discharge operation start signal coincides with the operation period of the purified water discharge operation recorded in the timer 192 of the controller 190, the purified water discharge operation end signal is transmitted. When the elapsed time after transmitting the integer filling operation start signal coincides with the operation period of the integer filling operation recorded in the timer 192 of the controller 190, the integer filling operation end signal is transmitted. At this time, the timer 192 of the controller 190 transmits a water purifying operation signal to the device controller 194 of the controller 190 and transmits a pipe cleaning signal to the display unit 260 to display the display unit 260. By operating the lamp of the purified water discharge status indicator of) to indicate that the purified water in the water pipe 110 of the dental unit chair is discharged to inform the user that there is no purified water in the purified water in the water pipe 110 As such, the hand piece 220 of the dental unit chair is not operated.

These signals are transmitted in the order of the water discharge operation start signal, the discharge operation end signal, the water purification start signal and the water purification end signal, which is the water pipe 110 when the dental unit chair is not used for a certain period of time. This is because it is necessary to fill the purified water in the water pipe 110 in order to remove the purified water in the) and use the dental unit chair again.

In addition, the device control unit 194 of the control unit 190 receiving the discharge operation start signal changes the first valve 130 to an off state (if it is normally using a dental unit chair, it is in an on state). Also, the second valve 170 is opened (closed when the dental unit chair is normally used), and the third valve 180 is closed (open when the dental unit chair is normally used. Is present) discharge operation to discharge the purified water in the water pipe 110 to the outside through the water pipe (160).

After the discharging operation proceeds for a predetermined time, the operation period of the discharging operation recorded in the timer 192 of the controller 190 is compared with the elapsed time after transmitting the discharging operation start signal, and if the time is identical. The timer 192 of the controller 190 transmits a discharge operation end signal to the device controller 194.

In addition, the device controller 194 of the controller 190 receiving the discharge operation end signal closes the second valve 170 to complete the purified water discharge operation. At this time, the first valve 130 should be maintained in an off state, because if it is changed to the on state, purified water may flow from the water purification pipe 100 into the water pipe 110.

Therefore, the controller 190 compares the operation time of the integer filling operation recorded in the timer 192 with the current time, and if the integer filling operation time is equal to the current time, the controller 190 of the controller 190 of the controller 190. Sends a fill operation start signal.

In addition, the device controller 194 receives the filling operation start signal, changes the first valve 130 to an on state, opens the second valve 170, and supplies purified water to the water pipe 110. Flow to perform the integer filling operation.

After the constant filling operation is performed for a predetermined time, the device controller 194 closes the second valve 160 after receiving the filling operation end signal, and opens the third valve 180 to open the purified water. Complete the filling operation.

Therefore, according to the present invention, by performing the purified water discharge operation and the purified water filling operation as described above, when the dental unit chair is not used for a predetermined time, the purified water is prevented from being stagnated by removing the purified water in the water pipe 110. The biofilm on the inner wall of the water pipe 110 may be prevented from occurring.

In addition, the present invention is a second embodiment, using the first valve 130 and the third valve 180, the water pipe 110 (from the water purification pipe 100, the first valve 130 of almost all sections) ), As well as a method for discharging the purified water in the first pipe 210 which is branched from the master block 120 and connecting the hand piece 220 to the place where the water pipe 110 is located). do.

First, a user or a manufacturer inputs an operating time and a period of the purified water discharge operation and an operating time and a period of the purified water filling operation through the input unit 250.
