The present invention relates to a dental water supply device, and more particularly, to a dental water supply method and apparatus for supplying silver ions to the dental water to increase the antibacterial and sterilizing power.

In general, the water supplied to the dental medical device is used to remove the powder and debris generated when cooling and grinding the heat generated in the handpiece of the dental unit chair or to brush the oral cavity. For this reason, hygiene and cleanliness are important, and in particular, since the direct contact with the wound of the oral cavity, the importance of antibacterial and bactericidal effects is emphasized. In addition, handpieces and scalers come into contact with contaminated teeth and affected areas, and various bacteria present in the contaminated areas form biofilm on hoses and water tanks connected to dental medical devices such as handpieces and scalers. Not only can the bacteria propagate, but the problem of the bacterial secondary infection or cross infection to other patients must be solved.

In addition, the conventional dental water supply device requires a lot of cleaning and disinfection in the tank that stores the water is often required to take the cost and effort in maintenance, and if the management is neglected, it causes hygiene problems.

For the hygiene and sterilization of the dental water supply, various chemicals and ozone have been conventionally used. However, antibiotics have limitations in their function, so more antimicrobial and bactericidal effects are sought.

On the other hand, silver (Ag) has been proven to be effective in sterilizing various bacteria from ancient times, and is used as jewelry or health products. Especially, silver ions (Ag +) have the strongest antibacterial effect among antibacterial methods by metal ions and have no skin irritation. The residual effect is continuous and stable, and even the parts not sterilized by ozone are completely sterilized. In order to use such silver usefully in the human body, the most effective method has been found to be most preferably used colloidally in the silver ion (Ag +) state. Dissolving silver ions (Ag +) in distilled water is called colloidal silver and is widely used as an alternative health therapy. Such silver ionized water is reported to sterilize about 650 bacteria, and above all, unlike general antibiotics, it is characterized by not being resistant. Silver ionized water is generated from such a small amount of minerals as purified water, and is extremely safe to use even in young children, and has no side effects of antibiotic resistance built by pharmacies.

A control unit 60 is provided for controlling the heater 16 and the pumps 3a and 3b and providing an interface with the manager.

Raw water is tap water or ground water supplied from a water supply source, or water supplied through an air gap device 170 as shown in FIG. 7, and is supplied to the water purification unit 2 via the raw water pipe 37 and the first solenoid valve 1a. do.

The water tank 10 is made of stainless steel (SUS), etc., and the inside thereof is coated with Teflon or resin having excellent corrosion resistance or chemical resistance. Since water flowing from the pumps 3a and 3b is controlled by the water level adjusting means including the ball top 34 and the controller 64, the water stored in the water tank 10 is always maintained at a constant level. In other words, the water tank 10 is supplied with water at a constant pressure by the first water supply pipe 32 and the pumps 3a and 3b penetrating into the water tank 10. Therefore, since water is supplied to the water tank 10 without opening and closing the lid, secondary pollution of the water tank 10 contaminated by contaminated air occurs when water is supplied in the conventional water tank which opens the lid to supply water. It doesn't work.

The auxiliary water tank 51 is stored in water to cope with the water cut and is made of stainless steel (SUS). The solenoid valve 1e connected to the auxiliary water tank 51 may be electrically controlled by the controller 64 but may be replaced by a manual valve.

The thioal filter 8 removes the unpleasant taste and smell in the water and supplies purified water to the cold / hot water for drinking water from which the taste and smell are removed.

The pump 3a is driven by the power supplied from the adapter 4a under the control of the controller 64 to supply the water purified by the water purification unit 2 to the water tank 10 at a constant pressure. Raw water is smoothly supplied to the purified water unit 2 by this pump 3a, and the water purified by the purified water unit 2 is smoothly filled in the water tank 10. For example, when the pressure of the raw water is low, the pure water is pressurized by the pump 3a to a predetermined pressure or more, so that the water purification process is smoothed by the water purification unit 2. The pump 3a supplies the purified water to the water tank 10 at a constant pressure until stopped by the controller 64.

The auxiliary pump 3b is driven at the time of failure of the pump 3a under the control of the controller 64 to supply raw water to the water purification unit 2 and the water tank 10 at a constant pressure. If the pump 3a is not a single stage, the water level of the water stored in the water tank 10 becomes abnormally low. In this case, when the water level of the water stored in the water tank 10 is sensed for a predetermined time or less below the lower limit level, the controller 64 determines that the pump 3a is fixed and drives the auxiliary pump 3b.

The controller 64 controls the 3-way valve 5b to maintain a constant water level in the water tank 10, and the solenoid so that the water stored in the auxiliary water tank 51 can be supplied to the water tank 10 at the time of watering. The valve 1e is controlled. Water stored in the auxiliary water tank 50 at the time of water supply is directly supplied to the water tank 10 via the auxiliary water supply pipe 38 and the solenoid valve 1e.

While the air pressure of the compressed air purified by the air purifier 26 is 8 to 6 kgf / cm ² , the air pressure of the compressed air controlled by the pressure regulator 27 is maintained at 1.8 to 2.5 kgf / cm ² . The water stored in the water tank 10 by the compressed air compressed at a constant air pressure is subjected to a constant pressure. As a result, the compressed air generated from the compressed air supply unit 40 flows into the water tank 10, so that the water stored in the water tank 10 by the compressed air is supplied to the dental unit chairs 101 to 10k at a constant pressure. Supplied. Water supplied to the dental unit chairs 101 to 10k is supplied to the final stage medical devices 71 to 7k such as handpieces, mouthwashes, and scalers.

3 is a view showing a silver ion supply apparatus according to a first embodiment of the present invention.

Referring to FIG. 3, the water tank includes a ball top 34, an ozone lamp 13, a temperature sensor 15, a heater 16, a water level detection detector 18a, 18b18c, and a silver ion supply device ( 80).

Ball top 34 is air is injected into the buoyancy is generated to float on the water surface in the water tank (10). The ball tower 34 is connected to the other side of the lever hinged one side not shown and is moved up and down according to the water level in the water tank to push up or down the water supply plug not shown. The water supply port stopper opens and closes the water supply port in conjunction with the vertical movement of the ball top 34.

The water level detection sensors 18a, 18b, and 18c are located corresponding to the upper limit level, the intermediate level, and the lower limit level in the water tank 10, respectively, and generate a level detection signal Sh.

The controller 64 is difficult to supply water to the water tank 10 due to a failure of the pump 3a or a blockage of the reverse osmosis filter 7 when the lower limit water level detection signal is input for a predetermined time or more among the water level detection signals Sh. It is determined that the auxiliary pump 3b is operated and the three-way valve 5b is operated so that the pores between the pot sediment filter 24 and the first water supply pipe 32 have large pores (UF) membrane filter 70. Through the water tank 10 to be filled in a short time.

When the water level is at the high water level, a signal from the high water level sensor 18a is applied to the controller 64, and the controller 64 controls to close the feed water supply switch valve. If the electrical control function is abnormal, the water supply port of the first water supply pipe 32 is blocked to prevent the water in the water tank 10 from overflowing in the ball top 34. When the water supply port of the first water supply pipe 32 is blocked by the ball tower 34, the pressure in the first water supply pipe 32 reaches or exceeds the set pressure and stops the pumps 3a and 3b so that no more water is used. It does not flow into the tank 10.

The temperature sensor 15 senses the temperature of the water stored in the water tank 10 and supplies a temperature detection signal St indicating the temperature of the water to the controller 64. In response to the temperature detection signal St, the controller 64 determines that the temperature of the water stored in the water tank 10 is maintained at a predetermined temperature, for example, 5 ° C. or lower for a predetermined time, to prevent freezing. ). The heater 16 then raises the temperature in the water tank 10 under the control of the controller 64 to prevent freezing.

The ozone lamp 13 is discharged by the power from the power supply unit 14. Instead of the ozone lamp 13, an ozone generating device which electrolyzes water and then converts oxygen into ozone water using a discharge can be used. This ozone generator is more effective when the dissolved oxygen amount of water stored in the water tank 10 is low.

The silver ion supply device 80 supplies silver ionized water so that the water in the water tank 10 maintains a constant silver ion concentration. Water sterilized by the ozone lamp 15 and having sterilization power has stronger sterilization and antibacterial power as silver ions are added.

The silver ion supply device 80 supplies power to a pair of silver electrodes 83, a silver ion water concentration sensor 81 for detecting a concentration of silver ion water in the water tank 15, and the silver electrode pair 83. And a controller 64 for controlling the operation of the silver ion supply device while periodically changing the polarity of the power applied to the silver electrode pair 83 by controlling the power supply unit. When power is applied to the silver electrode pairs 83 from the power supply unit, silver ions are dissolved into water by electrolysis, and dental water becomes silver ionized water. The controller 64 controls the power supply unit according to the silver ion concentration in the water tank sensed by the silver ion water concentration sensor 81. The concentration of silver ion water having bactericidal power is generally 0.01 ppm or more, but since it is water changed into ozone water by an ozone lamp, even a small amount of silver ions can improve the bactericidal power.

Water in the water tank 10 is to prevent the generation of silver chloride (AgCl) harmful to the human body by the chlorine (Cl) component contained in the general water to use, purified water or distilled water is used.

The silver ionized water is supplied to the dental unit chairs 101 to 10k via the water discharge pipe 12 and supplied to the plurality of water tanks 10 via the water return pipe 12 as shown in FIG. ) And the unit chair to circulate continuously to maintain the sterilizing power in the pipe. For example, conventionally, since water in the water discharge pipe 12 provided between the water tank 10 and the dental unit chairs 101 to 10k is stagnant when water is not discharged from the dental unit chairs 101 to 10k. Even if the water is sterilized, it will lose its sterilizing power over time. In this case, the tube or hose installed between the water tank 10 and the dental unit chairs 101 to 10k is infected, and the infection causes the water tank 10 or the mouth of the patient to become secondary infection. On the contrary, in the dental water supply device according to the present invention, the water stored in the water tank 10 is converted into ozone water, and contains silver ions, so that the sterilizing power is strong and the ozone water containing the silver ions loses sterilizing power. By not doing so, the pipes 12 and 19 provided between the water tank 10 and the dental unit chairs 101 to 10k are always sterilized.

In addition, the dental water supply apparatus according to the present invention is a chemical tank 52, chemical supply pipe 53 and solenoid valve for supplying a strong sterilizing and disinfecting chemicals to the water flowing through the water discharge pipe 12 as shown in FIG. 55, a pump 3c for circulating water, and a three-way valve 54 provided in the water return pipe 19. In the sterilization mode, the sterilizing water and the medicine mixed with the water are used for the dental unit chairs (101 to 10k), the handpiece, the mouthwash, the scale and the tube in the end medical device (71 to 7k). Are sterilized and disinfected. In this full sterilization mode, the three-way valve 54 connected to the water return pipe 19 for a predetermined time connects the water return pipe 19 and the sewage treatment unit for treating the waste water under the control of the controller 64, In the normal driving state not in the sterilization mode, the connection between the water return pipe 19 and the sewage treatment unit is blocked, and the water supply path between the water return pipe 19 and the water tank 10 is opened.

The solenoid valve 55 connected to the chemical supply pipe 53 opens the chemical supply path between the chemical tank 52 and the water discharge pipe 12 in the full sterilization mode, while the chemical in the normal driving state, not the full sterilization mode. The chemical supply path between the tank 52 and the water discharge pipe 12 is blocked and the water supply path between the water discharge pipe 12 and the water tank 10 is opened.

The medicine stored in the chemical tank 52 takes the form of liquid or powder and is supplied to the water discharge pipe 12 in a piston manner. Drugs include Sodium Hypochlorite (NaOCl), Chloramine, Elemental Chlorine, Chlorhexidine, Hydrogen Peroxide (H ₂ O ₂ ), Iodine Composition ) At least one.

The pump 3c is connected to the water discharge pipe 12 or the water return pipe 19 to circulate water between the water discharge pipe 12 and the water return pipe 19 or to sterilize the water discharge pipe 12 in the full sterilization mode. One water is pumped to the sewage treatment unit.

In the entire sterilization mode, it is preferable that the water outlet of the last stage medical devices 71 to 7k installed in each of the dental unit chairs 101 to 10k is opened. This is because the water dispensing ports of the terminal medical devices 71 to 7k must be opened so that the chemicals are mixed and water having sterilization power by ozone can be sterilized and disinfected to the water outlets of the medical devices 71 to 7k.

The operation time of the entire sterilization mode is set in advance in the controller 64. The solenoid valve 54 connected to the water return pipe 19 and the solenoid valve 55 connected to the chemical supply pipe 53 may be replaced by a manual valve. In this case, when it is determined that the entire disinfection is necessary, the manager closes the manual valve connected to the water return pipe 19 and opens the manual valve connected to the chemical supply pipe 53.

4 is a view showing a silver ion supply apparatus according to a second embodiment of the present invention.

In this embodiment, the same components as those of the above-described embodiments will be denoted by the same reference numerals as those of the above-described embodiments, and detailed description thereof will be omitted.

Referring to Figure 4, the silver ion supply device according to an embodiment of the present invention is a small silver ion water tank 91 and silver ion water connected to the water tank (10) connecting the water tank 10 and the final stage medical equipment A silver ion supply device 90 is provided inside the tank 91.

Water primarily stored in the water tank 10 is secondaryly stored in the silver ionized water tank 91 via the water outlet pipe 11. The water stored in the silver ionized water tank 91 becomes silver ionized water by the silver ion supply device 90. The silver ion water stored in the silver ion water tank 91 is a high concentration of silver ion water, not water that is finally supplied. When there is the use of the final stage medical device, the controller 64 controls the valve 92 to inject a high concentration of silver ionized water into the water passing through the water discharge pipe 12 so that the finally discharged water is at a proper concentration of silver ionized water. Be sure to In addition, when there is no use in the final stage, water is supplied to the silver ionized water tank 91 to store high concentration of silver ionized water. A certain amount of time is required to obtain an appropriate concentration of silver ionized water. Thus, the provision of a small silver ionized water tank can shorten the time required to produce silver ionized water in the tank.

However, even in this case, when one silver ion water tank is used, if water is supplied from the water tank to the silver ion water tank according to the demand of the finally discharged silver ion water, there may be insufficient time for adjusting the appropriate silver ion concentration. In order to ensure sufficient time to meet the demand, the amount of water used in the final stage may not be met.

5 is a view showing a silver ion supply apparatus according to a third embodiment of the present invention.

Referring to Figure 5, the silver ion supply device according to the present invention is connected to the water discharge pipe 12 connecting the water tank 10 and the final stage medical device 12 or more small silver ion water tank having a water level sensor inside (111,112 ... 11m, where m is a natural number). Each silver ion water tank (111, 112 ... 11m) is provided with silver ion supply devices (100a, 100b ...) therein.

In the present embodiment, since the contents of the ball top 34, the temperature sensor 15, the ozone lamp 13, and the chemical tank 52 are the same as those of the first and second embodiments described above, the description thereof will be omitted.

Water primarily stored in the water tank 10 is secondarily stored in the silver ionized water tanks 101 via the water outlet pipe 11.

The silver ion supply device 100 supplies silver ionized water to the silver ionized water tanks 111, 112... 11m so that water has an appropriate concentration of silver ion.

In order to discharge water to the final stage medical device, first water of the first ionized water tank 111 is used, and for this, the first and second discharge pipe valves 103b are opened and all other valves are closed. Water in the first silver ionized water tank 111 is discharged through the water discharge pipe by the pressure difference in the water tank from the device. When the water of the first silver ionized water tank 111 is exhausted, the water of the second silver ionized water tank 112 is used, and the first silver ionized water tank 111 receives water from the water tank 10 to receive silver ionized water. Manufacture.

The timing controller 64 receives a signal by a water level sensor not shown in each of the silver ionized water tanks, determines whether the silver ionized water remains in the silver ionized water tanks, and controls the valves.

The repetition of the above operations may be performed manually without automatic control. For example, when the level of each silver ion water tank is notified to the display device by a signal, opening and closing of the valve is performed manually. In addition, the water level of the silver ionized water tank can be made visible to the naked eye for simplicity of the controller.

If more than one silver ionized water tank is provided in this manner, the silver ionized water is maintained at an appropriate concentration in each silver ionized water tank, and the water of any one of the silver ionized water tanks is used and the water level is lowered from the water tank. While taking water and adjusting it to the appropriate concentration of silver ionized water, it is possible to use the appropriate concentration of silver ionized water at all times because water from another silver ionized water tank is used.

6 is a view showing a silver ion supply apparatus according to a fourth embodiment of the present invention.

Referring to FIG. 6, the silver ion supply device according to the fourth embodiment of the present invention is configured to discharge water from the silver ionized water tank 121 and the silver ionized water tank 121 installed on the flow path in the water discharge pipe 12. A flow rate sensor 125 is provided at the inlet of the discharge pipe.

The ionized water production apparatus 110 installed in the silver ionized water tank 121 supplies silver ions to ozone water under the control of the controller 64.

The flow rate sensor 125 detects the water flowing in the water discharge pipe and sends a signal to the controller 64 when there is the use of water from the final stage medical device.

The controller 64 increases the silver ion concentration of the ozone water by driving the silver ionized water production apparatus 110 when the flow rate in the water discharge pipe 12 increases in response to a signal from the flow rate sensor 125, that is, when dental water is used. On the other hand, when the flow rate in the water discharge pipe 12 decreases, that is, when the dental water is not used, the operation of the silver ionized water production apparatus 110 is stopped.

By providing a tank 121 including the silver ionized water production apparatus 110 in the water discharge pipe 12, it is possible to simplify the structure of the entire apparatus. In addition, since the water flowing into the silver ionized water tank 121 is already water having sterilization power by chemicals and ozone, the sterilizing power and the antimicrobial power can be increased even by adding a small amount of silver ions immediately before being discharged to the final stage.

7 is a view schematically illustrating the air gap device 170.

Referring to FIG. 7, the air gap device 170 includes a tank 174 on which an inlet pipe 171, a water outlet pipe 172, and an overflow outlet 173 are formed.

The water supply pipe 171 is supplied with tap water or ground water supplied from a water supply source. The inlet of the inlet 171 is located at the top of the tank 174.

The outlet pipe 172 is connected to the outlet port formed on the bottom of the tank 174 to supply the water stored in the tank 174 to the water purification unit 2.

The overflow outlet 173 is formed at the side wall of the tank 172 between the inlet of the inlet pipe 171 and the outlet of the outlet formed in the bottom of the tank 172. Therefore, an air gap of a predetermined height exists between the inlet port of the inlet pipe 171 and the overflow outlet 173.
