Abstract

The present invention relates to an aseptic water supplying system using electrolysis, which supplies sterilized water using electrolysis. The aseptic water supplying system using electrolysis in the present invention kills bacteria in water through electrolysis by sensing the flow of water and supplying power to an electrolytic bath, and supplies the water to a water pipe. More particularly, the aseptic water supplying system of the present invention comprises: a main valve which controls the flow of water and is installed at the rear side of the electrolytic bath; and a pump which is connected to the rear side of the main valve and a basin containing a disinfectant and supplies the disinfectant to a water pipe. The aseptic water supplying system closes the main valve if water is not used for a long period of time and instead operates the pump to supply the disinfectant to the water pipe, thereby preventing proliferation of bacteria inside the water pipe.

Description

[0001] The present invention relates to an aseptic water supply system using electrolysis,

The present invention relates to an aseptic water supply system using electrolysis to prevent the propagation of bacteria in a water tube and to supply water not contaminated with bacteria.

Dental care is usually done on a unit chair that allows the patient to comfortably lie down. The unit chair is equipped with a variety of necessary tools for physician consultation and treatment.

The dental unit chair requires water for oral cleaning of the patient, water to cool the frictional heat of the handpiece, and water for cleaning the medical device and for cleaning the hands of the patient or the doctor.

The water supplied to the handpiece of the dental unit chair may be used as it is or may be supplied by using a filtration device, but since the sterilization is not performed, the risk of infection after treatment is high, There is a problem that a film is formed and the flow path is clogged.

For this reason, the American Academy of Dentists (A.D.A.) recommends keeping the number of bacteria per ml of dental water from the handpiece or tip of the skeleler below 200 CFU / ml. This standard is much more stringent than the US NHS drinking water standard of 500 CFU / ml.

For this purpose, a method of sterilizing bacteria by electrolyzing water passing through a water tube has been developed. When the water is electrolyzed, the bacteria inside the water will be destroyed by destroying the cell wall, and the Cl (chlorine) component present in the water will be changed into HOCl or OCl ion and the sterilizing power will be obtained.

However, not only the amount of HOCl and OCl ions generated is small, but also the chlorine component is removed by the carbon filter when passing through a water purifier, so that HOCl and OCl ions are hardly generated. As a result, the electrolyzed water maintained its sterilizing power for a short time, but the bacteria grow in the water stagnated inside the water tube at night or on the holiday when the work is finished and the bacteria are released when the treatment is restarted. And biofilm may be generated.

Disclosure of the Invention The present invention has been made in order to solve the above problems and provides a sterile water supply system capable of suppressing bacterial propagation in a water pipe even when water is not used as well as supplying sterile sterile water when water is used .

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide an aseptic water supply system for supplying water to a water tube through which electricity is supplied to an electrolytic cell by sensing the flow of water, A main valve installed in the main body and controlling the flow of water; And a pump connected to the rear side of the main valve and connected to the container containing the disinfectant to supply the disinfectant into the water pipe. When the water is not used for a long period of time, the main valve is closed and the pump is operated. Thereby preventing the bacteria from propagating in the water tube.

A drain valve is provided on the rear side of the main valve to open the drain valve before the pump is operated for a long period of time to discharge the water inside the water pipe to the outside to lower the water pressure.

The present invention supplies sterilized sterilized water through electrolysis during use of water, and prevents disinfection by introducing disinfectant into the inside of the water tube according to user's operation during the time when water is not used, It is possible to prevent the biofilm formation inside the water tube.

1 is a schematic diagram of an aseptic water supply system using electrolysis according to an embodiment of the present invention;

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention in the drawings, portions not related to the description are omitted, and like reference numerals are given to similar portions throughout the specification.

Whenever a component is referred to as "including" an element throughout the specification, it is to be understood that the element may include other elements, not the exclusion of any other element, unless the context clearly dictates otherwise.

The sterilized water supply system using electrolysis according to the present invention is suitable for supplying various kinds of water used in hospitals, and can be used for stably supplying aseptic water required in a dental unit chair.

1 shows a configuration diagram of an aseptic water supply system using electrolysis of the present invention.

As shown in the figure, the aseptic water supply system using electrolysis comprises an electrolytic bath 100, a flow rate sensor 200, a control circuit 300, and a power supply 400.

The electrolytic bath 100 is constructed such that two or more electrodes are arranged in parallel and water can pass through the electrolytic bath 100. The electrolytic bath 100 is hermetically sealed except for the inlet and the outlet for the water to prevent the water from leaking to the outside. When an electric current is supplied to the electrode of the electrolytic bath 100, the cell walls of the bacteria passing through the electrolytic bath 100 are opened and water is infiltrated into the electrolytic bath 100 by the osmotic pressure.

When the electric current is continuously supplied to the electrolytic bath 100, the electrode is decomposed and consumed. Therefore, the flow sensor 200 is installed at the rear side of the electrolytic bath so that electrolysis can be performed only when water is used.

The signal sensed by the flow sensor 200 is transmitted to the control circuit 300. The control circuit 300 analyzes the signal of the flow sensor 200 and senses the flow rate to generate a current To the electrolytic bath (100).

The present invention further comprises a main valve 500 and a pump 600 in the aseptic water supply system configured as described above.

The main valve 500 is installed on the rear side of the electrolytic bath 100 to control the flow of electrolyzed water. During use of the water, the main valve 500 is opened so that water passing through the electrolytic bath 100 can be supplied to the water pipe 800 side.

When the water is not used for a long period of time, for example, after work, vacation, holidays, etc., the main valve 500 is shut off to prevent water passing through the electrolytic bath 100 from being supplied to the water pipe 800 side.

And the pump 600 is connected by branching the pipe on the rear side of the main valve 500. [ The pump 600 is connected to a container 610 containing a disinfectant so that when the pump 600 operates, the disinfectant in the container 610 is discharged. The pump 600 is not operated during the use of water and operates when water is not used for a long period of time, that is, when the main valve 500 is shut off, thereby supplying disinfectant into the water pipe 800. Accordingly, even when water is not used, disinfectant is present in the water pipe 800, so that the bacteria introduced from the outside can be removed.

However, while the main valve 500 is opened, the pressure inside the water pipe 800 is kept the same as the pressure of the raw water. Since the pressure inside the water pipe 800 is maintained as it is when the main valve 500 is locked without using water, the pressure inside the water pipe 800 is high even when the pump 600 is operated, It is necessary to lower the pressure inside the water pipe 800 before the pump 600 is operated.

To this end, in the present invention, the drain valve 700 is installed by branching the piping on the rear side of the main valve 500. When the drain valve 700 is opened, the water inside the water pipe 800 is discharged to the outside through the drain valve 700 by the water pressure, so that the pressure inside the water pipe 800 drops. The disinfection agent can be easily introduced when the pump 600 operates because the water pressure is maintained even when the drain valve 700 is closed.

The duct connected to the drain valve 700 connects an empty container which can be directly connected to a sewer or the like and collects the drained water.

In the embodiment of the present invention, hypoxic hypochlorous acid water is used as the disinfectant supplied into the water tube. The hypoxic hypochlorous acid water is a liquid having a pH of about 5 to 6.5, which is produced by electrolysis of hydrochloric acid. In the present invention, the effective chlorine concentration of the acidic hypochlorous acid water in the container connected to the pump 600 is about 20 to 30 ppm before being supplied to the water pipe.

The sterilized water supply system using the electrolysis of the present invention is connected between the raw water supply pipe and the water pipe in the dentistry and the main valve 500 is opened when the power is turned on so that the water can be used.

When the user then uses a handpiece or the like in the unit chair connected to the end of the water pipe 800, the valve in the dental unit chair is opened and water flows. When the flow sensor 200 senses the flow of water, the control circuit 300 supplies current to the electrolytic bath 100 to supply sterilized water, which has killed the bacteria, to the water pipe 800. When water is used on the unit chair side, electrolysis is performed. If water is not used, the flow of water is cut off, and the water is not electrolyzed.

When the step of the dentist selects the standby mode at the time of leaving work, the control circuit 300 first blocks the main valve 500. Thereafter, the control circuit 300 opens the drain valve 700 to drop the pressure inside the water pipe 800. After the drain valve 700 is closed again, the pump 600 is operated to supply the acidic hypochlorous acid water into the water pipe 800. Since the water inside the water tube contains a mixture of water and hypochlorous acid, there is a possibility that the germs in the water pipe are killed by the acidic hypochlorous acid water. Therefore, even if water is not used for several days, It becomes impossible to reproduce.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be.

It is therefore to be understood that the embodiments described above are intended to be illustrative, but not limiting, in all respects.
