  • a dental clean water treatment system according to the present invention 100 includes a first valve being 3 -way valve 160 and a turbidity measuring sensor 150, which are positioned on a predetermined location of the clean water pipe 120.
  • the dental clean water treatment system 100 outlets residual clean water in the clean water pipe 120 into the drain pipe 140 using a compressed air inlet from an air pipe 180 depending on a measurement value of the turbidity measuring sensor 150.
  • the water purifier 110 is connected to a water acquisition pipe including a raw water valve 11 for controlling on/off of raw water, i.e., tap water.
  • the water acquisition pipe 10 purifies the raw water inlet therefrom and then outlets the purified raw water into the clean water pipe 120 via an outlet opening.
  • the water purifier 110 plays a role in removing impurities (e.g., rusty water, bacilli, microbes) mixed in raw water.
  • the water purifier 110 includes a plurality of filters, a motor pump and a purification tank, and a typical purifier may be used as the water purifier.
  • the clean water pipe 120 is connected to surroundings of the outlet opening of the water purifier 110.
  • the clean water pipe 120 is connected to various dental treatment devices included in the unit chair 130 and a water supply pipe 121 for supplying clean water to dental treatment assistant devices.
  • a cut-off valve 170 is installed on a predetermined region of the water supply pipe 121, so that it is possible for clean water to be interrupted into the unit chair 130.
  • the first valve 160 as 3-way valve includes a mobility path connecting the clean water pipe 120 and the air pipe 180.
  • This first valve 160 inlets clean water supplied from the clean water pipe 120 into unit chair 130 during turned on state. During turned off state, this first valve 160 interrupts clean water of the clean water pipe 120 and at the same time, outlets compressed air inlet from the air pipe 180 toward to the unit chair 130.
  • the first valve 160 is installed on a start point of the clean water pipe 120. The reason for this is that when residual clean water in the clean water pipe 120 is outlet using compressed air supplied from the air pipe 180, it is necessary that the first valve 160 is connected to the start point of the clean water pipe 120 connected to the outlet opening of the water purifier 110. As a result, more large portions of the clean water pipe 120 can be cleaned.
  • the turbidity measuring sensor 150 measures turbidity in the clean water pipe 120, and then inputs the measured turbidity data to the control unit 190.
  • the turbidity in the clean water pipe 120 can be measured using various measuring methods. For instance, the turbidity in the clean water pipe 120 is found using light or measuring the degree of scale covering a resistance measurement means included in the clean water pipe 120.
  • the turbidity measuring sensor 150 is installed on the end of the clean water pipe 120.
  • the reason for this is that it is possible to measure real turbidity inlet into the unit chair 130 by installing the turbidity measuring sensor 150 on the clean water pipe 120 next to the unit chair 130 that is finally connected to the clean water pipe 120.
  • the drain pipe 140 is connected to the end of the clean water pipe 120, thereby out- letting clean water in the clean water pipe 120 via the drain pipe 140.
  • the control unit 190 controls the first valve 160. At this time, the control unit 190 compares a turbidity measurement value in the clean water pipe input from the turbidity measuring sensor 150 with a critical value of predetermined turbidity, thereby controlling the first valve 160. That is, the control unit 190 maintains the first valve 160 to be on state if the turbidity measurement value is smaller than the critical value. In contrast, if the turbidity measurement value is larger than the critical value, the control unit 190 makes the first valve 160 to be off-state. Thus, when the first valve 160 is at off-state, clean water remained in the clean water pipe 120 is outlet into the drain pipe 140 by compressed air supplied from the air pipe 180. At this time, the cutoff valve 170 of the water supply pipe 121 is performed, thereby preventing clean water from being inlet into the unit chair 130.
  • control unit 190 is connected to a displaying unit 191. Accordingly, if the turbidity measurement value measured by the turbidity measuring sensor 150 is input to the control unit 190, this turbidity measurement value is transmitted into the displaying unit 191 and, then displayed to be visible to users.
  • control unit 190 is connected to the alarming unit 192. If there is high turbidity in the clean water pipe 120, an alarm signal is generated. As a result, it is possible for users to acknowledge turbidity level in the clean water pipe 120.

  • the water purifier 110 is connected to an acquisition pipe 10 including a raw water valve 11.
  • the water purifier 110 purifies raw water supplied from the acquisition pipe 10 to discharge it to the clean water pipe 220 via the outlet opening.
  • the clean water pipe 220 is connected neighboring the outlet opening of the water purifier 110.
