Hereinafter, the entire configuration of the sterilizing water supply system 1 according to one embodiment of the present application will be described with reference to Figs. 1 and 2. Fig.

The sterilization water supply system 1 according to an embodiment of the present application may be a system for generating and safely supplying sterilized water having a sterilization power of a predetermined level or higher in a medical facility, an industrial facility, a residential facility, or the like.

FIG. 1 is a block diagram schematically illustrating an overall configuration of a sterilization water supply system 1 according to one embodiment of the present application, and FIG. 2 is a block diagram of a sterilization water supply system 1 according to an embodiment of the present application FIG. 7 is a graph illustrating an exemplary concentration of the sterilized water supplied over time. FIG.

1, a sterilization water supply system 1 according to an embodiment of the present application includes a sterilization water production apparatus 100, a storage unit 200, a supply unit 300, a water return pipe 400, and the like .

The sterilization water generating apparatus 100 may be a device for generating sterilized water using raw water supplied from the outside.

For example, the sterilizing water generator 100 may be an apparatus for generating sterilized water by electrolyzing raw water without adding any chloride. The detailed configuration and operation of the sterilizing water generator 100 will be described in more detail in the following related portions.

The storage unit 200 may be a storage tank for storing sterilized water generated from the sterilization water generator 100 described above.

In addition, the storage unit 200 may be designed to have different capacities according to the needs of the user, and may be formed in various forms.

For example, the storage unit 200 may be formed of a material or a shape suitable for storing the sterilized water.

As another example, the storage unit 200 may be formed of a material or a shape suitable for maintaining the concentration of the sterilizing water generated from the sterilizing water generating apparatus 100.

The supply unit 300 may be configured to supply sterilized water stored in the storage unit 200 to one or more destinations.

That is, referring to FIG. 1, the supply unit 300 may be a supply pipe for supplying the sterilized water to the use place 1 to the use place 5.

For example, the use may be a medical office or an operating room located in a medical facility. At this time, the user can immediately use the sterilized water supplied through the supply pipe 300 by opening the water supply or discharge valve located in the clinic or the operating room.

The chlorine concentration of the sterilizing water supplied to the use site through the supply pipe 300 may be preferably at least the minimum concentration required for performing the sterilizing function. This is because, if a certain level of sterilization water can not be supplied smoothly in a medical facility such as a hospital, it may cause various medical accidents.

At this time, the minimum concentration required to perform the sterilization function may differ depending on the characteristics of each facility or the requirements of the user.

The water return pipe 400 may be a separate pipe for discharging water having a reduced concentration of sterilized water in the supply unit 300 described above.

The water return pipe 400 may be provided at one side of the supply unit 300 to discharge sterilized water stagnated in the supply unit 300. This is because when the sterilization water supplied through the supply unit 300 is not used in the place of use, the concentration of hypochlorous acid in the sterilization water decreases and the sterilization power may be lost.

For example, as shown in Fig. 2, it can be seen that the concentration (ppm) of sterilized water continuously decreases from 2.64 to less than 2 over time.

Therefore, the sterilization water supply system 1 according to an embodiment of the present application can further reduce the concentration of sterilized water by discharging the sterilized water having a reduced concentration by providing the water supply pipe 400 in the supply unit 300, The sterilized water can be supplied continuously.

A separate valve B is further provided between the supply unit 300 and the water return pipe 400 to discharge sterilized water supplied from the storage unit 200 to the supply unit 300 through the water return pipe 400 .

For example, referring to FIG. 1, a solenoid valve B may be installed on one side of the water return pipe 400. The solenoid valve B is a valve that is automatically opened when no current flow is detected.

Therefore, when the flow of the current in the sterilized water supply system 1 is not detected, the solenoid valve is opened and the sterilized water stagnated in the supply part 300 can be automatically discharged through the water return pipe 400.

However, in the case where only the solenoid valve B is installed in the water return pipe 400, even when the user does not use the sterilized water temporarily, the solenoid valve B is opened to unnecessarily discharge the sterilization water having the sterilization power above the minimum reference concentration There may be a problem.

Therefore, a separate device may be required so that the solenoid valve B is opened when the user does not use the predetermined sterilizing water and / or when the concentration of the sterilizing water falls below the preset concentration.

For example, a timer (not shown) may be further provided on one side of the solenoid valve B.

At this time, if the supply of sterilized water from the storage unit 200 to the supply unit 300 is not detected for a predetermined time or longer, the solenoid valve may be opened to automatically discharge the sterilized water through the water return pipe.

Alternatively, if supply of the sterilized water from the supply unit 300 to the at least one use destination is not detected for a predetermined time or longer, the solenoid valve may be opened to automatically discharge the sterilized water through the water return pipe 400 have.

The preset time may be a value arbitrarily set to continuously supply sterilization water at a concentration desired by the user.

For example, as shown in FIG. 2, it can be confirmed that the concentration of the sterilized water is reduced by about 30% to about 1.8 ppm when about 4 hours have elapsed. Therefore, when the user desires to receive sterilized water of 2 ppm or more, the timer can be set so that the solenoid valve B is opened when sterilized water is not used at the place of use for 3 hours.

As another example, a sensor (not shown) may be further provided at one end of the valve B.

At this time, the sensor may be a sensor for detecting the concentration of sterilized water stagnated in the supply unit 300. The control unit (not shown) may control the valve B to be opened when the concentration of sterilized water detected by the sensor is less than a predetermined concentration.

As another example, both the timer and the sensor may be provided at one end of the valve B.

At this time, the controller can control to open the valve B when it is determined that the predetermined time has elapsed and the concentration of the sterilization water detected at one end of the supply part 300 is equal to or less than a predetermined value.

Therefore, according to the sterilization water supply system 1 according to the embodiment of the present application, sterilizing water having a sterilization power stagnated inside the supply part 300 is discharged to the outside through the water return pipe 400, It is possible to continuously provide sterilization water having a minimum concentration capable of performing the function.

Hereinafter, the configuration and operation of the sterilizing water producing apparatus 100 according to one embodiment of the present application will be described in detail with reference to FIGS. 3 to 6. FIG.

3 is a diagram for explaining an internal configuration of a sterilizing water producing apparatus 100 according to an embodiment of the present application.

3, the sterilizing water producing apparatus 100 according to an embodiment of the present invention includes at least one electrolyzer 110, a rectifier 120, a controller 130, a sensor 140, a check valve 150, And the like.

The electrolytic bath 110 is an apparatus for electrolyzing raw water to produce hypochlorous acid. The electrolytic bath 110 can be connected to the inlet I and electrolyze the raw water flowing through the inlet I.

The capacity and shape of the electrolytic bath 110 may be designed in various ways depending on the purpose of use and the needs of the user.

For example, in the case of a large-capacity sterilization water generator 100 used in an industrial facility such as a medical facility, an appropriate capacity can be designed in consideration of installation area, purpose of use, scale of use, and other user's requirements.

For example, even when an electrolytic cell of the same capacity is used, the concentration of chlorine ions detected in the raw water differs depending on the local characteristics, and consequently the concentration of the sterilizing water produced may vary. For example, in an area using ground water as raw water, the concentration of chlorine ions detected in raw water may be low.

Therefore, in the case of the industrial sterilizing water producing apparatus, it is necessary to determine the capacity of the electrolytic cell by inspecting the components of the raw water in advance for each region to be installed.

As another example, in the case of a small sterilizing water generating device for use in a home or a specific space, it can be designed to be a size that can be accommodated in an interior space of a sink for convenience of installation and use.

 As another example, it is possible to design an electrolytic cell of a standard size without providing an individual design of the electrolytic cell according to the characteristics of each facility, and to connect the plurality of electrolytic cells according to the user's need. At this time, a plurality of electrolytic baths may be provided in the form of one module.

For example, the standard may be calculated on the basis of the national average chlorine ion concentration.

Referring to FIG. 3, a plurality of standard capacity electrolytic cells may be arranged in series in the sterilizing water producing apparatus 100 according to the embodiment of the present application.

For example, when sterilized water is produced using the first electrolytic cell 110a, the second electrolytic cell 110b, and the third electrolytic cell 110c, the first electrolytic cell 110a electrolyzes the raw water, Can be produced.

At this time, the second electrolytic bath 11b can receive the sterilized water having the first concentration from the first electrolytic bath 110a, and electrolyzes the sterilized water having the first concentration again to generate the sterilized water having the second concentration .

In the same manner, the third electrolytic bath 110c can be supplied with the sterilized water having the second concentration from the second electrolytic bath 110b, electrolyzed again the sterilized water having the second concentration, Lt; / RTI >

That is, when the sterilizing water producing apparatus using a plurality of electrolytic baths according to an embodiment of the present application is used, the concentration of chlorine ions can be sequentially amplified through electrolysis.

Therefore, according to the sterilizing water producing apparatus according to an embodiment of the present invention, it is possible to use one or more standard electrolytic baths connected to each other so as to generate sterilized water having required sterilizing power in consideration of the characteristics of raw water in each region , And the manufacturing cost of the product can be lowered.

The rectifier 120 is electrically connected to the electrolytic bath 110 to provide a current for performing electrolysis.

As an example, in the case where a plurality of electrolytic baths are provided, one or more rectifiers for providing current to each electrolytic bath may be provided.

For example, as shown in FIG. 3, when sterilizing water is generated using the first electrolytic cell 111a, the second electrolytic cell 111b, and the third electrolytic cell 111c, The first rectifier 120a, the second rectifier 120b, and the third rectifier 120c may be provided, respectively.

The control unit 130 may receive power from the external power source P to control the operation of the at least one electrolyzer 110.

For example, the control unit 130 may control the amount of current applied to one or more electrolytic cells according to a target concentration set in advance by the user.

As another example, when a plurality of electrolytic cells are provided as shown in FIG. 3, the control unit 130 may be capable of generating a desired concentration of hypochlorous acid by activating at least one of the plurality of electrolytic cells according to a predetermined target concentration .

For example, when the user sets the first target concentration, the control unit 130 generates the hypochlorous acid number of the first target concentration by applying only the first current and the second current to the first electrolytic cell and the second electrolytic cell, respectively can do.

Alternatively, for example, when the user sets the first target concentration, the controller 130 applies the third current, the fourth current, and the fifth current to the first electrolytic cell, the second electrolytic cell, and the third electrolytic cell, respectively The hypochlorous acid number of the first target concentration can be generated.

At this time, there may be a variety of ways in which the controller 130 turns on / off a plurality of electrolytic cells and applies an amount of current to each electrolytic cell to generate a hypochlorous acid number of a predetermined target concentration. The electrolytic bath can be operated.

The sensor 140 may be a sensor for detecting the flow of the raw water flowing into the sterilizing water producing apparatus 100 through the inlet I.

For example, the sensor 140 may be a flow rate sensor, and the controller 130 may apply a current to the at least one electrolyzer 110 based on a signal sensed by the sensor 140.

Further, although not shown in the figure, a sensor for detecting the concentration of chlorine remaining in the raw water may be further provided.

Meanwhile, in the sterilizing water supply system according to another embodiment of the present application, the sterilizing water producing apparatus 100 is provided separately from the controller 130 for controlling the operation of the sterilizing water producing apparatus 100 .

The sterilizing water producing apparatus 100 may include one or more electrolytic baths 110 and the controller 130 for controlling the operation of the electrolytic bath 110 may include a sterilizing water generating device 100, 1 position by a predetermined distance or more.

For example, the sterilization water generator 100 may be installed at a first location, such as an underground site in a building where the sterilization water supply system 1 is located, And may be installed at a second position separated from the first position by a predetermined distance or more.

Alternatively, for example, the sterilizing water producing apparatus 100 may be provided in the sterilizing water supply system 1 described above in a supply path for supplying the sterilizing water generated from the electrolyzer 110 to one or more places of use And the control unit 130 may be installed at a position (second position) close to the external power source P for supplying power to the electrolyzer 110.

Therefore, the sterilization water generating apparatus 100 can be controlled to generate sterilization water of a predetermined concentration according to a signal received from the control unit 130 located at the outside.

In another example, in the case where the electrolytic bath 110 is constituted by a cylindrical housing, the cylindrical electrolytic bath 110 may be directly connected to a supply pipe for supplying the sterilized water generated in the electrolytic bath 110 to one or more uses have.

At this time, when the electrolytic bath 110 receives an input signal for operating the electrolytic bath 110 from the controller 130, the electrolytic operation can be started and the sterilized water generated from the electrolytic bath 110 can be supplied to the supply pipe Can be supplied directly to the user.

For example, one or more electrolytic cells may be connected in series to the supply pipe, and the operation of generating sterilizing water by the at least one electrolytic cell 110 may be sequentially performed in the same manner as in the above-described embodiment.

As another example, the sterilization water generator 100 may include one or more electrolytic cells and a cylindrical housing, and the one or more electrolytic cells may be disposed in series within the cylindrical housing and attached to one side of the supply pipe

Therefore, the sterilizing water supply system 100 according to another embodiment of the present invention is provided separately from the control unit 130, so that the sterilizing water generating apparatus 100, regardless of the position of the external power source, Can be installed at a position desired by the user. Furthermore, the controller 130 for controlling the operation of the sterilizing water generator 100 can be controlled more conveniently by providing the sterilizer water generator 100 at a desired position.

Meanwhile, the sterilizing water producing apparatus according to one embodiment of the present application may further include a check valve 150.

The backflow prevention valve 150 prevents the water flowing into the sterilizing water generator 100 through the inlet I from flowing out in the reverse direction to prevent the sensor 140 from unnecessarily operating.

For example, when the outlet valve is opened to use the sterilized water in the place of use, the raw water flows into the check valve 150 and passes through the sensor 140. The control unit 130 may operate the at least one electrolytic cell 120 to generate sterilized water based on the signal detected from the sensor 140. The sterilized water generated in the electrolytic cell may be supplied to the storage tank 200 And can be supplied to the use place.

If the user does not use the outlet valve for a long period of time while the outlet valve is shut off, the flow rate and the hydraulic pressure fluctuation may be caused in the pipe according to various parameters of the peripheral use source in the raw water supply pipe, This phenomenon can be mistaken for the sensor 140 to be inflow of water.

The control unit 130 may operate one or more electrolytic cells 120 to perform electrolysis according to a signal that is erroneously detected by the sensor 140. At this time, hydrogen gas due to electrolysis is generated in the electrolytic bath 120. If the above phenomenon occurs repeatedly, hydrogen gas generated in the electrolytic bath 120 may not be discharged to the outside, and the electrolytic bath may be damaged.

3, it is possible to reduce the risk of breakage of the electrolytic cell due to malfunction of the sensor 140 by further attaching the check valve 150 between the inlet I and the sensor 140. [

Hereinafter, the structure of the interior of the electrolytic cell according to one embodiment of the present application will be described in more detail with reference to FIGS. 4 to 6. FIG.

FIG. 4 is a view for explaining a shape of an electrolytic cell according to an embodiment of the present application, and FIG. 5 is a cross-sectional view for explaining an internal configuration of an electrolytic cell according to an embodiment of the present application. 6 is a diagram for explaining a shape of an electrode according to an embodiment of the present application.

As described above, the electrolytic bath 110 is a device for electrolyzing raw water to generate hypochlorous acid. The electrolytic bath 110 includes a housing H, a plurality of first electrode plates 110a and a second electrode plate 1000b, a first electrode rod 1112a, A second electrode rod 1112b, and the like.

At this time, a first path may be provided to one side of the housing (H) for transferring raw water or sterilized water into the electrolytic bath (110) for electrolysis. For example, the first path may be an inlet (I) into which raw water or sterilization water flows.

A second path may be provided on the other side of the housing H for discharging electrolyzed sterilized water passing through electrodes disposed in the electrolytic bath 110 to the outside. For example, the second path may be connected to a storage unit 200 for storing the sterilized water or a supply unit 300 for providing the sterilized water to one or more uses.

The housing (H) may be a three-dimensional shape for disposing a plurality of electrode plates for performing electrolysis therein.

For example, the housing H according to the first embodiment of the present application may have a rectangular shape such as a hexahedron or a rectangular parallelepiped so that a plurality of electrodes can be stacked.

However, when the housing H is manufactured in a rectangular shape, it is easy to stack a plurality of electrode plates, but the outer shape of the housing is easily deformed at a high water pressure, and various housings must be manufactured in accordance with the increase / decrease of the capacity of the electrolytic bath. .

Alternatively, for example, the housing H according to the second embodiment of the present application may have a cylindrical shape as shown in FIG. 4, and a plurality of electrode plates may be disposed inside the cylindrical housing.

At this time, a method of arranging a plurality of electrode plates in the cylindrical housing H may be various.

For example, a plurality of electrode plates can be arranged in the lateral direction so as to be parallel to the height direction of the cylinder. In this case, however, the number of electrodes that can be disposed inside the electrode capacitance may be limited.

Alternatively, for example, as shown in FIG. 4, a plurality of electrode plates 1110a and 1110b may be stacked in the vertical direction so as to be perpendicular to the height direction of the cylinder. In this case, since electrodes can be added along the height of the cylinder, there is an advantage that more electrodes can be stacked.

Referring to FIG. 4, a plurality of first electrode plates 1110a and second electrode plates 1110b may be alternately arranged in the housing H described above. At this time, the first electrode plate 1110a and the second electrode plate 1110b may be formed in an appropriate number according to a predetermined capacity.

On the other hand, the shape of the electrode plate disposed inside the housing H may vary. For example, the first electrode plate 1110a and the second electrode plate 1110b may be substantially rectangular or circular in shape. The shape of the first electrode 1110a and the second electrode 1110b is not limited to the shape described above and may be formed in various shapes that can be stacked in the electrode housing H.

For example, referring to FIG. 4, when a plurality of electrodes are arranged in the cylindrical housing H along the height of the cylindrical housing, it may be efficient to stack electrodes of generally circular shape.

The first electrode plate 1110a may be an anode or a cathode and the second electrode plate 1110b may be configured to have a polarity opposite to that of the first electrode 1110a.

In addition, the first electrode plate 1110a and the second electrode plate 1110b are insoluble electrodes, and may be formed of a metal material.

For example, the surfaces of the first electrode plate 1110a and the second electrode plate 1110b may be composed mainly of an iridium (Ir) compound, a ruthenium (Ru) compound, and a tin (Sn) (Ti) compound, a molybdenum (Mo) compound, a tantalum (Ta) compound and a zirconium (Zr) compound.

 Also, for example, a chloride may be used for each element compound of the coating layer, and the thickness of the coating layer may be formed within a predetermined thickness. For example, when the thickness of the coating layer is less than 3 占 퐉, the coating layer may be damaged by friction or hydrogen bubbles. Further, for example, when the thickness of the coating layer is more than 10 mu m, there is a possibility that crystal grains or abnormal crystal grains are formed during the thermal decomposition process of the compound to peel off. Therefore, the thickness of the coating layer of the first electrode plate 1110a and the second electrode pin 1110b according to an embodiment of the present invention may be preferably 3 to 10 占 퐉.

6, when circular electrodes are used, a first electrode 1112a and a second electrode 1112b are formed on one side of the first electrode plate 1110a and the second electrode plate 1110b, respectively, Openings 1120a and 1120b for connection may be respectively provided.

For example, the openings 1120a and 1120b may be formed in various shapes to connect the electrode rods to apply the current to the first electrode plate 1110a and the second electrode plate 1110b.

For example, the openings 1120a and 1120b may be formed at different positions so that positive and negative electrode currents can be applied to the first electrode plate 1110a and the second electrode plate 1110b by crossing each other, .

For example, referring to FIG. 6, the openings 1120a and 1120b may be formed at the peripheral portions of the first electrode plate 1110a and the second electrode plate 1110b, have.

At this time, the positions of the openings provided in the plurality of first electrodes may coincide with each other, and the positions of the openings provided in the plurality of second electrodes may coincide with each other.

That is, the first electrode bar and the second electrode bar can be disposed through the openings provided on one side of the plurality of first electrodes and the second electrode, and a positive current is applied to the first electrode bar and a negative current .

Therefore, the raw water flowing into the housing H can be electrolyzed while passing between the first electrode plate 1110a and the second electrode plate 1110b.

On the surfaces of the first and second electrode plates 1110a and 1110b, a plurality of voids may be provided on the surface of the first electrode plate 1110a and the second electrode plate 1110b so that the raw water introduced into the housing H can smoothly pass between the electrodes.

For example, as shown in FIG. 6, the surfaces of the first electrode and the second electrode may be formed in the form of a mesh.

Therefore, according to the electrolytic bath 110 according to the embodiment of the present application, water flowing into the housing H through the air formed on the surface of the plurality of electrodes can be passed through, and the sterilized water can be efficiently generated.

In addition, the first electrode plate 1110a and the second electrode plate 1110b may be periodically switched to a cathode or an anode. When the electrode is used for a long time in one direction, foreign substances such as K, Ca, and Mg are deposited on the negative electrode (-) of the electrode, thereby increasing resistance of the electrode and causing current unevenness of the electrode.

This causes deterioration of the efficiency of electrolysis and shortening of the life of the electrode. Thus, conventionally, in the use of the electrolytic apparatus using the electric relay system, the negative electrode (-) and the positive electrode (+ Respectively. However, if alternating operation is performed periodically, it may be an impediment to the function and durability of the electrolytic cell due to frequent changes in current flow inside.

Therefore, the sterilizing water producing apparatus 100 according to an embodiment of the present invention can alternately perform the alternate operation at the next reuse after the use of the sterilizing wash water is stopped without performing the alternate operation during the operation.

That is, the polarities of the first electrode plate 1110a and the second electrode plate 1110b can be switched each time the operation of the electrolyzer 110 is started.

In addition, since the apparatus 100 for generating sterilization water according to an embodiment of the present invention may cause safety accidents such as explosion, overheating, etc. during the electrolysis process, various devices for preventing and blocking the sterilization water may be provided.

For example, when the flow of raw water by the flow sensor 140 is not detected and a predetermined time has elapsed, the controller 130 may control the power to be supplied to the sterilizing water generator 100 to be shut off .

That is, when the sterilizing water producing device is not used, the sensor 140 can function as a safety sensor for preventing an explosion accident caused by continuous power supply of the electrolytic device.

As another example, an automatic air vent 1114 may be further attached to one side of the electrolyzer 110, as shown in FIG. The automatic air vent 114 is a device that automatically discharges the gas to the outside when the pressure is increased by air generated in the inside.

As described above, when sterilization water generated by the sterilization water generator 100 is supplied through the supply unit 300 and the user stops using water for a predetermined time, the controller 130 supplies power to the electrolyzer 110 Can be blocked. However, there may be a case where a current is continuously applied to the electrolyzer 110 due to an unexpected abnormality such as a malfunction of the apparatus. At this time, hydrogen (H ₂ ) and oxygen (O ₂ ) gas are generated by the electrolysis process in the electrolyzer 110, so that when the pressure rises, the electrolyzer 110 may explode.

Accordingly, an automatic air vent 1114 is further provided on one side of the electrolyzer 110, so that the gas can be automatically discharged to the outside when an abnormal pressure is generated in the electrolyzer 110. A silicone packing (not shown) may be further attached to the automatic air vent 114.

As another example, a temperature sensor (not shown) may be further provided on one side of the electrolytic bath 110.

The temperature sensor may be a bimetallic temperature sensor configured to detect a temperature for preventing overheating of the interior of the electrolyzer 110.

For example, a metal conduction plate may be attached to the surface of the electrolytic bath 110 and connected to the control unit 130 to control the sterilization water generator 100 according to the temperature detected by the temperature sensor Can be.

That is, when the sterilization water generated by the sterilization water generator 100 is supplied through the supply unit 300 and the user stops using the water for a predetermined time or longer, the controller 130 cuts off power to the electrolyzer 110 . However, there may be a case where a current is continuously applied to the electrolyzer 110 due to an unexpected abnormality such as a malfunction of the apparatus.

Accordingly, when the temperature inside the electrolytic bath 110 continuously increases, the electrolytic bath 110 may be ruptured due to overheating. Therefore, when a temperature sensor is further provided on one side of the electrolytic bath 110 and the internal temperature of the electrolytic bath 210 is detected by the temperature sensor to exceed a predetermined safe use temperature, Can be designed to shut off power to the electrolyzer (110).

For example, when the temperature of the inside of the electrolytic bath 110 is detected to be higher than 40 degrees by the temperature sensor, the control unit 130 may cut off the power to the electrolytic bath 110.

Therefore, according to the sterilization water supply system according to the embodiment of the present invention, it is possible to provide a sterilization water supply system that secures safety and minimizes manufacturing and maintenance cost.

Hereinafter, the detailed construction and electrolysis process of the sterilizing washing water producing system 200 for generating hypochlorous acid sterilizing washing water according to another embodiment of the present invention will be described in detail with reference to FIG. 7 to FIG. FIG. 7 is a block diagram showing a schematic configuration of a sterilizing and washing water producing system according to another embodiment of the present invention, and FIGS. 8 to 10 are views showing the configuration of an electrode according to an embodiment of the present invention.

7, the sterilizing washing water generating system 100 may include an inlet I, an electrolyzer 110, a controller 130, a rectifier 120, a sensor unit 240, and the like.

The inlet (I) is a passage through which raw water flows from the outside, and can be connected to a pipe through which raw water flows.

The raw water is water used for process water, water, water reservoir, Guam water pipe, bottled tap water, village water supply, small water supply facility, ground water, spring water, drinking water, swimming pool and ballast water.

Generally, raw water introduced from the outside may be supplied to the hot water valve 20 and / or the cold water valve 30 in a connected state. For example, a sterilizing wash water generating system according to one embodiment of the present invention may be connected to a cold water valve 30.

The electrolytic bath 110 is an apparatus for electrolyzing raw water introduced from the inflow part I to generate sterilizing washing water. For example, the inlet (I) connected to a pipe through which raw water flows may be formed on one side of the electrolyzer (110).

Referring to FIG. 8, a plurality of first electrodes 221 and second electrodes 223 may be arranged at predetermined intervals in the electrolytic bath 110.

 The first electrode 221 and the second electrode 223 may be formed in an appropriate number according to the capacity of the sterilizing washing water generating system 200. For example, as shown in FIG. 8, three first electrodes 221 and four second electrodes 223 may be alternately arranged.

The first electrode 221 may be an anode or a cathode and the second electrode may have a polarity opposite to that of the first electrode 223, that is, a cathode or an anode.

At this time, the first electrode 221 and the second electrode 113 can be switched to a cathode or an anode each time the operation of the electrolyzer 110 is started. When the electrode is used for a long time, foreign substances such as K, Ca, and Mg are deposited on the negative electrode (-) of the electrode, thereby increasing the resistance of the electrode and causing current unevenness of the electrode. This degrades the efficiency of electrolysis and shortens the service life of the electrode. Thus, in the related art, the negative electrode (-) and the positive electrode (+) are periodically alternated by using electric relays to prevent the degradation of the function. However, if alternating operation is performed periodically, it may be an impediment to the function and durability of the electrolytic cell due to frequent changes in current flow inside. Therefore, the sterilizing and washing water producing system 100 according to an embodiment of the present invention can be alternated at the time of the next reuse after the use of the sterilizing wash water is stopped in the sink without alternating operation during operation. Hereinafter, for convenience of explanation, it is assumed that the first electrode 221 is a cathode and the second electrode 223 is a cathode.

The first electrode 221 and the second electrode 223 are insoluble electrodes, and the surface of the first electrode 221 and the second electrode 223 is coated with a Pt group metal oxide. For example, the surfaces of the first electrode 221 and the second electrode 223 may be composed mainly of an iridium (Ir) compound, a ruthenium (Ru) compound, and a tin (Sn) ) Compound, a molybdenum (Mo) compound, a tantalum (Ta) compound, and a zirconium (Zr) compound. Further, for example, a chloride may be used for each element compound of the coating layer, and the thickness of the coating layer may be formed within at least a predetermined thickness. For example, when the thickness of the coating layer is less than 3 占 퐉, the coating layer may be damaged by friction or hydrogen bubbles. Further, for example, when the thickness of the coating layer is more than 10 mu m, there is a possibility that crystal grains or abnormal crystal grains are formed during the thermal decomposition process of the compound to peel off. Therefore, the thickness of the coating layer of the first electrode 221 and the second electrode 223 according to an embodiment of the present invention may be preferably 3 to 10 mu m.

9 (a), one side edge of the first electrode 221 may be formed to be inclined in the first direction. 9 (b), one side edge of the second electrode 223 may be formed to be inclined in a second direction opposite to the first direction. 9 (c) and FIG. 10, external electrodes may be connected to the protruding portions of the first electrode 211 and the second electrode 213. Referring to FIG. The first terminal rod 222 and the second terminal rod 224 may be mounted to maintain a gap between the first electrodes 221 and the second electrodes 223, respectively. The first electrode 221 and the second electrode 223 may be alternately arranged at a predetermined interval. For example, the first electrode 221 and the second electrode 223 may be alternately arranged with a gap of about 0.3 mm Spaced apart.

Therefore, according to the sterilizing and washing water producing system 100 of the embodiment of the present invention, the water introduced from the inflow section I can flow between the first electrodes 221 and the second electrodes 223 A sterilizing wash water can be generated while passing through.

The sensor unit 240 may include a sensor for detecting the flow of the raw water flowing into the inlet I. For example, when the flow of raw water by the sensor unit 240 is not detected and a predetermined time has elapsed, the controller 130 may control the power supply to the sterilizing water washing apparatus 100 to be shut off .

That is, the sensor unit 240 may function as a safety sensor to prevent an explosion accident caused by continuous power supply to the electrolytic apparatus when the sterilizing water cleaning apparatus is not used.

In addition, the sensor unit 240 may further include a function of detecting the chlorine concentration remaining in the raw water.

In particular, when the sterilizing water washing apparatus 100 is implemented in a large capacity, it is necessary to keep the hypochlorite ion concentration of the sterilizing washing water constant.

Accordingly, the controller 240 can detect the concentration of chlorine remaining in the raw water passing through the piping, and the controller 130 controls the concentration of chlorine in the electrolyzer 110 according to the concentration of chlorine detected by the sensor 240, Can be controlled.

For example, when the concentration of chlorine remaining by the sensor unit 240 is lower than a predetermined concentration, the controller 130 may increase the amount of current applied to the electrolyzer 110.

Alternatively, for example, the controller 130 may reduce the amount of current applied to the electrolyzer 110, which is detected by the sensor 240 as being higher than a preset concentration.

Meanwhile, the electrolyzer 110, the controller 130, and the rectifier 120 according to an embodiment of the present invention may be provided in a state accommodated in a case (not shown). The case may be made to have an appropriate size to be accommodated in the sink S,

Referring to FIG. 11, the apparatus 100 for generating sterilizing water according to an embodiment of the present invention may further include an automatic air vent 250.

The automatic air vent 250 is a device that automatically discharges the gas to the outside.

As described above, when the sterilizing wash water generated by the sterilizing water cleaning apparatus 100 is supplied through the supply unit 300 and the user stops using the water by the operation of the operation means 400, 130 can shut off the power to the electrolytic bath 110 when a predetermined time has elapsed without detecting the flow of raw water by the sensor unit 240.

However, there may be a case where a current is continuously applied to the electrolyzer 110 due to an unexpected abnormality such as a malfunction of the apparatus. At this time, hydrogen (H ₂ ) and oxygen (O ₂ ) gas are generated by the electrolysis process in the electrolyzer 110, so that when the pressure rises, the electrolyzer 110 may explode.

Accordingly, an automatic air vent 250 is further provided on one side of the electrolyzer 110, so that the gas can be automatically discharged to the outside when an abnormal pressure is generated in the electrolyzer 110.

11, a silicone packing 251 may be further attached to the automatic air vent 250.

Referring to FIG. 12, the apparatus 100 for generating sterilizing water according to an embodiment of the present invention may further include a temperature sensor 260. The temperature sensor 260 may be a bimetallic temperature sensor for detecting a temperature for preventing overheating of the electrolyzer 110. 12, a metal conductive plate 261 may be attached to the surface of the electrolytic bath 110, and a metal conductive plate 261 may be attached to the surface of the electrolytic bath 110, And may be connected to the controller 130 for control.

As described above, when the sterilizing wash water generated by the sterilizing water cleaning apparatus 100 is supplied through the supply unit 300 and the user stops using the water by the operation of the operation means 400, 130 can shut off the power to the electrolytic bath 110 when a predetermined time has elapsed without detecting the flow of raw water by the sensor unit 240.

However, there may be a case where a current is continuously applied to the electrolyzer 110 due to an unexpected abnormality such as a malfunction of the apparatus. Accordingly, when the temperature inside the electrolytic bath 110 continuously increases, the electrolytic bath 110 may be ruptured due to overheating.

The temperature sensor 250 may further include a temperature sensor 250 on one side of the electrolyzer 110. When the internal temperature of the electrolyzer 110 is detected by the temperature sensor 250 to exceed a predetermined safe use temperature, The control unit 130 may be designed to shut off power to the electrolyzer 110.

For example, when the temperature of the inside of the electrolytic bath 110 is detected to be higher than 40 degrees by the temperature sensor 250, the controller 130 may cut off power to the electrolytic bath 110.

Therefore, according to the present application, it is possible to provide a sterilizing washing water generating system capable of ensuring safety and minimizing the maintenance cost.

The sterilizing water producing system according to another embodiment of the present application is a sterilizing water producing system in which a sterilizing water producing device necessary for washing vegetables, fruits, dishes or the like at home or business or for washing various medical instruments in a hospital, So that sterilizing washing water can be easily used according to the user's needs. Hereinafter, a sink equipped with a sterilizing water cleaning system according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 13 is a perspective view of a sink equipped with a sterilizing and washing water generating system according to an embodiment of the present invention, and FIG. 14 is a block diagram showing a schematic configuration of a sink shown in FIG. FIG. 15 is a front view of a sink equipped with a sterilizing and washing water generating system according to an embodiment of the present invention, and FIG. 16 is a plan view of the sink shown in FIG.

Here, the sterilizing wash water may be water containing sterilizing and / or cleaning ions or salts such as hypochlorous acid. At this time, hypochlorous acid can be generated using the chlorine ion (Cl < - >) remaining in the raw water, and the general electrolysis method described above can be applied.

The sterilization and washing water producing apparatus 100 may include an electrolytic bath 110, a controller 130, a rectifier 120, a sensor unit 240, and the like.

The electrolytic bath 110 is an apparatus for electrolyzing raw water to produce hypochlorous acid.

The controller 130 controls the overall operation of the sterilizing water generator 100. [

The rectifier 120 is configured to supply power to the sterilizing water generator 100.

The sensor unit 240 may include a sensor for detecting the flow of raw water flowing into the inlet I, and may further be provided with a function of detecting the concentration of chlorine remaining in the raw water. The detailed configuration of the sterilizing washing water producing apparatus 100 will be described in more detail in the related section.

The supplying unit 300 is a unit for supplying the sterilizing washing water generated by the sterilizing washing water generating apparatus 100 or the general water supplied from the inlet I as it is.

The supplying part 300 may be connected to one side of the sterilizing water producing device 100 and may be connected to a faucet installed on the upper part of the sink S to supply water.

In addition, the supply part 300 may provide sterilizing washing water or general water. At this time, it is not necessary to separately provide a valve means for switching the supply path of the water to selectively provide sterilizing washing water or ordinary water.

In other words, the supply part 300 can be formed as a single flow path, and it is possible to provide a small-sized sterilizing water cleaning system with a safe and low manufacturing cost by allowing sterilizing water or general water to be supplied through one flow path .

The operating means 400 may be configured to open the supplying portion 300 to acquire the sterilizing washing water or the general water.

As shown in Figs. 15 and 16, for example, the operating means 400 may be in the form of a knob for starting supply of water from the receptacle of the sink S, regulating the supply amount, and stopping the supply of the water .

The user can adjust the supply of water as needed by operating the operating means (400). For example, when the user operates the operating means 400 to use water, the supplying portion 300 may be opened.

On the other hand, when the user operates the operating unit 400 to receive hot water of a predetermined temperature or higher, the controller 130 generates the hot water through the electrolytic bath 110 according to the amount of water supplied through the hot water valve 20 The concentration of the sterilizing wash water can be adjusted.

This is because when the hot water is supplied through the supply unit 300 and the hot water is mixed with the sterilizing wash water generated in the electrolyzer 110, the concentration of the sterilizing wash water may be lowered according to the proportion of the hot water to be mixed.

Therefore, in order to supply sterilizing washing water of a predetermined concentration or higher to the user, it is necessary to adjust the concentration of the aseptic washing water generated in the electrolytic bath 110 according to the ratio of the water supplied through the hot water valve 20 and the cold water valve 30 have.

The input unit 500 may be configured to start the operation of the sterilizing water washing apparatus 100. [

The input means 500 may be provided in various forms for the convenience of the user, and may be provided in the form of a push button, for example. Hereinafter, for convenience of explanation, it is assumed that the input means 500 is provided in the form of a push button.

In addition, the input means 500 may be waterproof. In the case of the sink (S), since it is always exposed to a large amount of moisture in use, a waterproof function of a certain level or more is required for the durability of the product.

Also, the input unit 500 may be connected to the controller 130 of the sterilizing washing water generator 100.

Hereinafter, an example of a control method of the sterilizing washing water producing apparatus 100 according to an embodiment of the present invention will be described with reference to FIG.

FIG. 17 is a flowchart illustrating a process of supplying sterilizing washing water or general water to a sink equipped with the sterilizing washing water generating apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 17, the controller 130 of the apparatus 100 for generating a sterilizing water according to an embodiment of the present invention can determine whether a first input signal is received (S2) If it is determined that the received signal has been received, the operation of the sterilizing water washing apparatus 100 may be started (S3). The sterilizing washing water generated from the sterilizing washing water producing apparatus 100 may be supplied through the supplying unit 300 (S4). The control unit 130 may then determine whether a second input signal is received during the sterilization wash water supply (S5). If it is determined that the second input signal is received, The operation can be stopped (S6). Alternatively, if the second input signal is not received, the sterilizing wash water can be continuously supplied through the supply unit 300. When the second input signal is received and the operation of the sterilizing water washing apparatus 100 is stopped, the general water can be supplied through the supplying unit 300 (S7). Each step will be described in detail below.

The controller 130 may determine whether a first input signal has been received (S2). For example, when the user presses the push button 500 for sterilizing wash water, a first input signal for initiating operation of the sterilizing wash water generator 100 may be received via the controller 130 .

If the first input signal is input through the input unit 500, the control unit 130 may control the sterilizing water cleaning apparatus 100 to start operation (S3). Accordingly, the sterilizing washing water generated from the sterilizing washing water producing apparatus 100 may be supplied through the supplying unit 300 (S4).

In addition, the controller 130 may determine whether a second input signal is received during the supply of the sterilizing wash water (S5). For example, when the user pushes the push button 500 again to stop the use of the sterilizing wash water during the supply of the sterilizing wash water, a second input signal for stopping the operation of the sterilizing wash water generating device 100 And may be received through the control unit 130. If the second input signal is input through the input unit 500, the control unit 130 may control the sterilizing water washing apparatus 100 to stop operating (S6). Accordingly, the chlorine concentration is reduced to 0.7 ppm or less within a few seconds, so that regular water other than the sterilizing wash water can be supplied (S7).

Hereinafter, an example of a control method of the sterilizing washing water producing apparatus 200 according to another embodiment of the present invention will be described with reference to FIG. 18 is a flowchart for explaining a control method of the sterilizing washing water generating apparatus 100 in the counter seat according to another embodiment of the present invention.

18, the control unit 130 of the apparatus 100 for generating a sterilizing water according to an embodiment of the present invention can determine whether a first input signal has been received (S20) If it is determined that the signal has been received, the operation of the sterilizing water washing apparatus 100 may be started (S30). The sterilizing washing water generated from the sterilizing water washing apparatus 100 may be supplied through the supplying unit 300 (S40). The control unit 130 can check whether the raw water flow is detected from the sensor unit 240 in step S50 and if the flow of raw water is detected by the sensor unit 240 in step S40, It is possible to control to supply washing water. Alternatively, if the flow of the raw water by the sensor unit 240 is not detected, the control unit 130 may determine whether a predetermined time has elapsed (S60). Accordingly, when the predetermined time has elapsed from the initial point of time when the flow of the raw water by the sensor unit 240 is not detected, the control unit 130 can control to shut off the power of the sterilizing washing water generating apparatus S70). Alternatively, if the predetermined time has not elapsed since the first time when the flow of the raw water by the sensor unit 240 is not detected, the controller 130 controls the flow of the raw water by the sensor unit 240 according to step S50. It is possible to confirm again whether or not it is detected. Hereinafter, each step will be described in detail. Since steps S20 to S40 correspond to steps S2 to S4 of FIG. 5 described above, detailed description will be omitted.

If the first input signal is received (S20), the control unit 220 may start the operation of the sterilizing water cleaning apparatus 100 (S30). Accordingly, the controller 130 may check whether the raw water flow is detected from the sensor unit 240 during the sterilizing wash water is supplied through the supply unit 100 in operation S40.

For example, during the supply of the sterilizing wash water, the supply unit 300 may be closed when the user operates the operation means 400 to stop the use of water. At this time, the control unit 130 may determine whether a predetermined time has elapsed when the flow of the raw water by the sensor unit 240 is not detected (S60).

The control unit 130 may control to shut off the power of the sterilizing washing water generator when a predetermined time has elapsed since the first time when the flow of the raw water by the sensor unit 240 is not detected at step S70.

When the user stops the supply of water while the push button 500 for stopping the operation of the sterilizing water washing apparatus 100 is stopped during use of the sterilizing water for washing, There is a risk of an explosion or the like.

Accordingly, when the user operates the operating unit 400 to close the supplying unit 300 during the use of the sterilizing water, the controller 130 controls the power supply to the sterilizing water producing apparatus 100 to be shut off within a few seconds can do.

As described above, the sterilizing and washing water producing apparatus according to another embodiment of the present invention is integrally provided at the lower part of the sink S so that the user can easily operate the input means to easily receive general water and sterilizing water ≪ / RTI >
