Auxiliary water tank 50, the ball tower 34, which floats buoyantly in the water stored in the water tank 10, and the water supply port by the ball tower 34 when the water stored in the water tank 10 reaches a certain level Is installed between the first water supply pipe 32, the second water supply pipe 33 installed between the water purification unit 2 and the cold / hot water heater 17 for drinking water, and the water purification unit 2 and the wastewater processor 9. Pressure for supplying the waste water pipe 31, the ozone lamp 13 installed in the water tank 10, the temperature sensor 15 and the heater 16, and the compressed air purified in the water tank 10. Solenoid valves (1a, 1b, 1c, 1d), three-way valves (5a, 5b) and heaters provided in the air supply unit 40, the pipes 31, 32, 33, and 34 through which water flows. 16) and a control unit 60 for controlling the pumps 3a, 3b, 3c and providing an interface with the manager.

The raw water is supplied to the purified water part through the raw water pipe 37 and the first solenoid valve 1a as tap water or ground water supplied from a water supply source.

The water tank 10 is made of stainless steel (SUS). The water flowing from the pump 3a is controlled by the water level adjusting means including the ball top 34 and the controller 64 so that 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 or 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 tank 50 is stored in water to cope with the water cut and is made of stainless steel (SUS).

The control unit 60 includes a controller 64, a memory 61 connected to the controller 64, a pressure regulator 27, a display device 62, and an input / operation panel 63. Detailed description thereof will be described later.

The water purification unit 2 serves to remove various foreign matters, debris, suspended matter, chemical pollutants, heavy metals, ions, bacteria, and the like contained in the raw water supplied from the raw water pipe 37. To this end, the water purification unit 2 is installed in series between the preseedment filter 21, the auxiliary pump 3b, and the second three-way valve 5b installed between the first solenoid valve 1a and the pump 3a. A pre-carbon filter 22, a post carbon filter 23 and a post sediment filter 24, a reverse osmosis filter 7 provided between the second three-way valve 5b and the water supply pipes 32, 33; The thioal filter 8 provided between the reverse osmosis filter 7 and the cold / hot water heater 17 for drinking water is provided.

The sediment filter (21, 24) is composed of a non-woven fabric, filter paper, etc. to remove various foreign matter, debris, suspended matter contained in raw water. The carbon filters 22 and 23 remove chemical pollutants. Reverse osmosis filter (7) is removed by the heavy metal, bacteria, ion membrane separation method using a membrane (Membrane) that blocks only heavy water (H ₂ O) and larger than the water molecules and blocks heavy metals, bacteria, and ionic substances. 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 water supplied from the water supply source 1 is low, raw water is pressurized by a pump 3a or more by a predetermined pressure or more, so that the water purification treatment 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.

Compressed air supply unit 40 includes a compressor 25, an air purifier 26 and a pressure regulator 27 connected in series as shown in FIG. The compressor 25 generates compressed air, and the air purifier 26 is composed of an air purifying filter made of a fine membrane such as a nonwoven fabric and a filtration device to remove various foreign matter dust contained in the compressed air compressed by the compressor 25. Remove The pressure regulator 27 adjusts the pressure of the compressed air purified by the air purifier 26 as a regulator operated by a manager. 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 this compressed air is maintained at a constant pressure to the dental unit chair at a constant pressure. Supplied. The water supplied to the dental unit chair is again supplied to the handpiece, the mouthwash stand, the scaler, and the like installed in the dental unit chair.

The ball tower 34 for opening and closing the water supply port formed at the end of the first water supply pipe 32 serves to prevent the water from overflowing in the tank 10 during the malfunction of the water level detection sensors 18a, 18b, and 18c. . To this end, the ball top 34 is air injected therein so that buoyancy is generated and floats on the water surface in the water tank 10. The ball tower 34 moves up and down according to the water level in the water tank 10 to open and close the water supply port of the first water supply pipe 32. That is, when the water level in the water tank 10 reaches a predetermined level, the ball tower 34 blocks the water supply port of the first water supply pipe 32. 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 is increased.

The pressure regulator 27 senses the pressure of the first water supply pipe 32 and stops the pump 3a when the pressure of the first water supply pipe 32 reaches a predetermined pressure or more, so that no more water is supplied to the water tank 10. Control not to enter.

The auxiliary pump 3b is driven at the time of failure or shortage of the pump 3a under the control of the controller 64 to supply the water stored in the raw water or the auxiliary water tank 50 to the water purification unit 2 and the water tank 10 at a constant pressure. Supply. In case of failure of the pump 3a, since the pressure of the first water supply pipe 32 is changed, the auxiliary pump 3b is driven by the controller 64 which senses this pressure change. When water is cut off, the water level stored in the water tank 10 becomes abnormally low. When the water level of the water stored in the water tank 10 is detected for a predetermined time or less below the lower limit level, the controller 64 determines the number of stages and drives the auxiliary pump 3b. In order to detect the water level during the water shortage, the water tank 10 is provided with water level detection sensors 18a, 18b, and 18c at positions corresponding to the upper limit level, the intermediate level, and the lower limit level, respectively. Each of the water level detection sensors 18a, 18b, and 18c generates a water 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 second three-way valve (5b) by operating the pores between the pot sediment filter 24 and the first water supply pipe (32) large membrane filter (UF) ( 70) to fill the water tank 10 in a short time.

On the other hand, the controller 64 controls the first and second three-way valves (5a, 5b) to switch the flow path of water so that the water stored in the auxiliary tank (50) can be supplied to the water tank (10) in the water shortage . At this time, the water stored in the auxiliary tank 50 is purified by the water purification unit 2 via the auxiliary water supply pipe 35, the fourth solenoid valve 1d, the first three-way valve 5a, and the auxiliary pump 3b. After the treatment, the water is supplied to the water tank 10 via the second three-way valve 5b and the third water supply pipe 36.

The ozone lamp 13 installed in the water tank 15 sterilizes the water stored in the water tank 10 by converting the water stored in the water tank 10 into ozone water. The water converted into ozone water by the ozone lamp 13 is sterilized and supplied to the water discharge pipe 12 via the water discharge pipe 11. The outlet pipe 11 is elongated to a nearly bottom position of the water tank 10 so that water can be supplied to the dental unit chair even when the water level is low. The water converted into ozone water by the ozone lamp 13, that is, sterilization water, is supplied to the dental unit chair via the water discharge pipe 19, and also through the water return pipe 12 as shown in FIG. 3. 10) is continuously supplied between the water tank 10 and the unit chair to maintain the sterilization power in the pipe. For example, conventionally, when water is not discharged from the unit chair, since the water in the water discharge pipe installed between the water tank and the unit chair is stagnant, the sterilizing power is lost even if the water is sterilized. In this case, the tube or hose installed between the water tank 10 and the unit chair is infected, and the infection causes the water tank or the oral cavity of the patient to become secondary infection. On the contrary, in the dental water tank automatic water supply device according to the present invention, water stored in the water tank 10 is converted into ozone water to have sterilization power and the ozone water is sterilized so that the sterilization power is not lost between the water tank and the dental unit chair. The water discharge pipe installed in the tank is always sterilized. The ozone lamp 13 is discharged by the power source from the adapter 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.

In addition, the dental water tank automatic water supply device according to the present invention prevents the stagnant water in the pipe to cool by circulating the heated water in the water tank 10 when the external temperature is low, such as winter, and dental unit chair It can effectively supply hot water to dental equipment.

In order to prevent leakage at a time other than the medical time without the manager, the controller 40 stops the pumps 3a and 3b and the compressed air supply unit 40 at a time other than the medical time input by the manager. Even in this case, the ozone lamp 13 is driven to continuously sterilize the water stored in the water tank 10. The treatment time information input through the input / operation panel 63 is stored in the memory 61.

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 input / operation panel 63 has an on / off key of a power supply, a pressure gauge indicating a water tank pressure, a keyboard, etc. to allow an administrator to control an automatic water tank for a dental water tank. It also monitors and regulates the water pressure. In addition, the manager may input and update information such as a medical treatment time through the input / operation panel 63.

The display device 62 displays the information input from the controller 64 so that the manager can know the operation state of the dental water tank automatic water supply device.

The wastewater processor 9 serves to discharge the wastewater supplied from the reverse osmosis filter 7 using a membrane having fine pores. The third solenoid valve 1c installed at both ends of the wastewater processor 9 is opened by bypassing the wastewater at a high flow rate without passing through the wastewater processor 9 under the control of the controller 64, thereby allowing the wastewater processor 9 to be opened. Remove the debris attached to the wall surface of the reverse osmosis filter (7) as a fine membrane.

The fourth solenoid valve 1d provided between the first three-way valve 5a and the auxiliary tank 50 is opened only when water is cut off under the control of the controller 64.

As described above, the dental water tank automatic water supply device according to the present invention automatically supplies the raw water supplied through the water purification unit from the water supply to the water tank at a constant pressure, and sterilizes the water stored in the water tank to generate ozone water. Supply the dental medical device at a constant pressure. As a result, the dental water tank automatic water supply apparatus according to the present invention does not need to pour water into the water tank, thereby minimizing the inconvenience of the administrator during water supply and preventing the infection of water stored in the water tank. By circulating the water with the water, the secondary infection caused by the tube or hose can be prevented, and the hot water is effectively supplied when the outside temperature is low, such as in winter, to reduce the pain of the patient when the cold water is supplied to the patient's syringe. I can alleviate it. In addition, the dental water tank automatic water supply apparatus according to the present invention can supply water to the water tank normally even in the event of failure or water shortage using the auxiliary water tank and the auxiliary pump, and detects the temperature to respond to the detected temperature of the water in the water tank.
