Description

Electrolyzed water generator

[0001] The present invention relates to an electrolytic water generating device, and more specifically, to an electrolytic water generating device that, when the discharge of the supply water itself without electrolysis of the supply water provided from the inlet line is required, allows the supply water to be bypassed so that it does not pass through the inside of the electrolytic cell and is discharged to the discharge line, and allows the supply water to pass through the inside of the electrolytic cell only when electrolysis of the supply water is required and to bypass the electrolytic cell when the supply water itself is simply discharged, thereby preventing the shortening of the lifespan of the electrolytic cell and each component constituting the electrolytic cell, and also suppressing the formation of scale inside the electrolytic cell.

[0002] Modern civilization, which is growing unhindered every year due to rapid industrial development, is facing a very serious situation regarding environmental pollution problems alongside this rapid growth.

[0003] Due to such environmental pollution, even water, which is an essential element for human survival that we must consume constantly, is being contaminated through various routes. Since people are generally aware of the problem of water pollution, they boil tap water before drinking, purify it with a water purifier, or purchase bottled water sold on the market to obtain drinking water that is harmless to the human body.

[0004] In particular, with the recent rise in public awareness of health, interest in water—essential for human survival—is on the rise day by day, and the public desires to be provided with water that is not merely harmless to the human body, but is more beneficial and safer for daily life.

[0005] In response to such public demand for water, various types of devices are being continuously developed to treat water in diverse ways and supply it in a form beneficial to the human body; an example of such a device is an electrolytic water generator.

[0006] An electrolytic water generator is a device that produces alkaline water (alkaline ionized water) and acidic water (acidic ionized water) by treating raw water, that is, generally tap water itself or purified water obtained through tap water purification.

[0007] This electrolytic water generator receives raw water through a solenoid valve, purifies the received raw water using a filter inside the generator, transmits it to an electrolytic cell via a flow control valve, and then generates alkaline and acidic water (ionized water) through electrolysis in the electrolytic cell, after which it is discharged through a flow switching valve.

[0008] Electrolyzed water can be classified as pure neutral water when the pH, which represents the hydrogen ion index, is 7, acidic water when the pH is less than 7, and alkaline water when the pH is greater than 7.

[0009] Among electrolyzed waters, weakly alkaline water is known to possess properties highly beneficial to the human body when consumed. It is widely used for its effectiveness in treating gastrointestinal symptoms such as chronic diarrhea, indigestion, abnormal fermentation in the stomach, and excessive stomach acid. Furthermore, strongly alkaline water has the potential to promote crop growth and improve soil, and it can clean dirty objects without the use of synthetic detergents.

[0010] Furthermore, acidic water is primarily used for sterilization purposes and is widely used, particularly for sterilization in food manufacturing processes, odor removal, and disinfection in livestock farming.

[0011] As such, an electrolytic water generating device can produce alkaline water and acidic water that can be beneficially used for various purposes, and as a related prior art, there is one disclosed in Korean Registered Patent Publication No. 10-2493547.

[0012] As illustrated in FIG. 1, a conventional electrolytic water generating device (1) comprises a device body (2) having an electrolytic cell (4) that electrolyzes water, and a water purification cartridge (5) that purifies water supplied to the electrolytic cell (4).

[0013] The water purification cartridge (5) is installed upstream of the electrolytic cell (4). Raw water is supplied to the water purification cartridge (5). Generally, tap water is used as the raw water, but other types of water, such as well water or groundwater, may also be used. The water purification cartridge (5) purifies the raw water by filtration and supplies the obtained purified water to the electrolytic cell (40).

[0014] Inside the electrolytic chamber (40), a positive feeder (41) and a negative feeder (42) are arranged facing each other. A diaphragm (43) is arranged between the positive feeder (41) and the negative feeder (42). The diaphragm (43) divides the electrolytic chamber (40) into a positive chamber (40A) on the positive feeder (41) side and a negative chamber (40B) on the negative feeder (42) side.

[0015] Water is supplied to both the positive chamber (40A) and the negative chamber (40B) of the electrolytic chamber (40), and a DC voltage is applied to the positive feeder (41) and the negative feeder (42), thereby supplying an electrolytic current (I) to the positive feeder (41) and the negative feeder (42), and electrolysis of water occurs within the electrolytic chamber (40).

[0016] The diaphragm (43) allows ions generated by electrolysis to pass through. The positive electrode feeder (41) and the negative electrode feeder (42) are electrically connected via the diaphragm (43). As water is electrolyzed within the electrolytic chamber (40), electrolytically reduced water is obtained in the negative electrode chamber (40B), and electrolytically acidic water is obtained in the positive electrode chamber (40A).

[0017] In the cathode chamber (40B), hydrogen gas is generated by electrolysis and dissolves into the water inside the electrode chamber (40B). Therefore, the electrolytically reduced water obtained from the cathode chamber (40B) is also called "electrolytic hydrogen water" and is effective in removing active oxygen (hereinafter referred to as "electrolytic hydrogen water").

[0018] The electrolytic hydrogen water obtained from the cathode chamber (40B) and the electrolytic acidic water obtained from the anode chamber (40A) are supplied to and discharged from a faucet (not shown) via a flow path switching valve (21). The flow path switching valve (21) is configured to switch the connection point while separating the flow path of the electrolytic hydrogen water obtained from the cathode chamber (40B) and the flow path of the electrolytic acidic water obtained from the anode chamber (40A).

[0019] However, these conventional electrolytic water generating devices have a problem in that, even when only purified water is required without electrolysis of water purified through a water cartridge, the purified water unnecessarily passes through the inside of the electrolytic cell before being discharged through the faucet.

[0020] In addition, conventional electrolytic water generation devices have a problem in that the lifespan of the electrolytic cell and its components is inevitably shortened because the purified water must always pass through the inside of the electrolytic cell regardless of whether electrolysis of the purified water occurs.

[0021] In addition, conventional electrolytic water generation devices have a problem in that scale frequently forms inside the electrolytic cell because the purified water inevitably passes through the inside of the electrolytic cell regardless of whether electrolysis of the purified water occurs.

[0022] In addition, conventional electrolytic water generating devices have the problem that they may cause inconvenience and hassle in use because the scale generated by the discharge of purified water must be managed frequently.

[0023] In addition, while conventional electrolytic water generation devices can typically remove scale inside the electrolytic cell by changing the polarity of the anode and cathode feeders, there is a problem in that it is difficult to remove scale formed on the flow switching valve connected to the electrolytic hydrogen water outlet of the electrolytic cell, the water outlet line connected thereto, and the faucet.

[0024] In addition, conventional electrolytic water generation devices have a problem in that it is difficult to control the flow rate of purified water supplied into the electrolytic cell according to changes in water pressure.

[0025] In addition, conventional electrolytic water generation devices generally have a problem in that stepwise control of the flow control valve and the flow switching valve is very difficult because the flow control valve and the flow switching valve are typically formed as a single unit and operated in conjunction.

[0026] In addition, conventional electrolytic water generation devices have the problem that the valve itself must be replaced when it is necessary to change the type and number of flow paths of the flow control valve and the flow path switching valve.

[0095] As illustrated in FIGS. 2 and 3, an electrolytic water generating device according to one embodiment of the present invention (hereinafter referred to as an electrolytic water generating device) may be a device for generating electrolytic water by electrolyzing supply water supplied internally.

[0096] Since the electrolysis process of the electrolytic water generating device is identical to the prior art, it is decided to refer to the prior art.

[0097] Referring to FIGS. 2 and 3, the electrolytic water generating device may include an intake line (L1).

[0098] The intake line (L1) may be a line that supplies water for producing purified water or electrolytic water, etc., provided by an electrolytic water generating device.

[0099] The inlet line (L1) can be provided with a tube or hose through which fluid can flow.

[0100] The intake line (L1) can be connected to the water supply on the upstream side, which is supplied to homes or various buildings.

[0101] Accordingly, the intake line (L1) can supply water provided from the above water supply to the downstream side.

[0102] Referring to FIGS. 2 and 3, the electrolytic water generating device may include a first valve module (100).

[0103] The first valve module (100) is an inlet valve module provided to supply water to the electrolytic cell (200) to be described later, and can be connected to an inlet line (L1).

[0104] The first valve module (100) can receive supply water from the inlet line (L1).

[0105] The first valve module (100) may be configured to be connected to the downstream side of the inlet line (L1) and to selectively control the flow of supply water supplied from the inlet line (L1).

[0106] For example, the first valve module (100) may have multiple flow paths inside, and may receive supply water through one of the multiple flow paths and selectively allow the supply water to flow to at least one of the remaining flow paths or control the flow rate of the supply water.

[0107] The first valve module (100) will be described in more detail later.

[0108] Referring to FIGS. 2 and 3, the electrolytic water generating device may include an electrolytic cell (200).

[0109] The electrolytic cell (200) may be a core component of an electrolytic water generating device for electrolyzing supply water into electrolytic water.

[0110] The electrolytic cell (200) may have an electrolytic chamber (200a) formed inside.

[0111] The electrolytic chamber (200a) may be a space where the supply water supplied to the interior is electrolyzed.

[0112] A diaphragm (230) may be placed inside the electrolytic chamber (200a).

[0113] The electrolytic chamber (200a) can be divided into a first electrode chamber (210) and a second electrode chamber (220) on both sides based on the diaphragm (230).

[0114] A first electrode (211) may be installed in the first electrode chamber (210), and a second electrode (221) may be installed in the second electrode chamber (220).

[0115] The first electrode (211) and the second electrode (221) can be arranged facing each other within the electrolytic chamber (200a).

[0116] Of the first electrode (211) and the second electrode (221), one may be a negative (-) electrode and the other may be a positive (+) electrode.

[0117] For example, depending on the voltage provided by default, the first electrode (211) can be a negative (-) electrode and the second electrode (221) can be a positive (+) electrode, and accordingly, the first electrode chamber (210) can be a negative electrode chamber and the second electrode chamber (220) can be a positive electrode chamber, and the electrolysis of the electrolytic cell proceeding in such a state can be described as electrostatic electrolysis in which alkaline ion water is generated in the first electrode chamber (210) and acidic ion water is generated in the second electrode chamber (220).

[0118] Additionally, as the voltage provided for removing scale inside the electrolytic cell (200) is applied in the opposite direction, the polarity of the first electrode (211) and the second electrode (221) may be reversed, and accordingly, the first electrode chamber (210) may become the positive electrode chamber and the second electrode chamber (220) may become the negative electrode chamber, and the electrolysis of the electrolytic cell proceeding in this state can be described as reverse electrolysis in which acidic ion water is generated in the first electrode chamber (210) and alkaline ion water is generated in the second electrode chamber (220).

[0119] In the electrolytic cell (200), unlike in FIG. 2, a plurality of first electrode chambers (210) and second electrode chambers (220) may be provided alternately, and accordingly, a plurality of first electrodes (211) and second electrodes (221) may also be arranged alternately, and a diaphragm (230) may be arranged between each of the first electrodes (211) and second electrodes (221).

[0120] At this time, multiple first electrode chambers (210) can be connected to each other, and multiple second electrode chambers (220) can be connected.

[0121] The electrolytic cell (200) can have an inlet and an outlet.

[0122] The inlet of the electrolytic cell (200) may include an inlet of the first electrode chamber (210) and an inlet of the second electrode chamber (220) for the inflow of supply water into the electrolytic chamber (200a), and the outlet of the electrolytic cell (200) may include an outlet of the first electrode chamber (210) and an outlet of the second electrode chamber (220) for the outflow of electrolytic water from the electrolytic chamber (200a).

[0123] One side of the electrolytic cell (200) can be connected to the first valve module (100).

[0124] For example, the electrolytic cell (200) can be connected to the downstream side of the first valve module (100) as the inlet of the first electrode chamber (210) and the inlet of the second electrode chamber (220) are connected to the first electrode chamber guide path and the second electrode chamber guide path to be described later of the first valve module (100).

[0125] The electrolytic cell (200) and the first valve module (100) can be directly connected.

[0126] That is, the first valve module (100) can be integrated with the electrolytic cell (200) by being combined in a manner such that the first fastener (112a) and the second fastener (113a), which will be described later, are mounted corresponding to the inlet of the first electrode chamber (210) and the inlet of the second electrode chamber (220).

[0127] However, the electrolytic cell (200) and the first valve module (100) may be indirectly connected through a separate medium as needed.

[0128] The electrolytic cell (200) can electrolyze the supply water supplied into the interior through the first valve module (100) into electrolytic water.

[0129] For example, the electrolytic cell (200) can electrolyze the supply water supplied to the first electrode chamber (210) and the second electrode chamber (220) through the first valve module (100) to produce the first electrolytic water on the first electrode chamber (210) side and the second electrolytic water on the second electrode chamber (220) side.

[0130] At this time, the first electrolytic water may be alkaline ionized water, and the second electrolytic water may be acidic ionized water.

[0131] As previously mentioned, the process of electrolyzing the supply water through the electrolytic cell (200) is a general matter, so we will refer to the prior art and omit the explanation.

[0132] Referring to FIGS. 2 and 3, the electrolytic water generating device may include a second valve module (300).

[0133] The second valve module (300) is a water outlet valve module provided to switch the flow path, such as guiding the electrolytic water generated in the electrolytic cell (200) to the water outlet line or drainage line (L3) described later, or guiding the cleaning water provided through the cleaning line (L5) described later to the water outlet line (L2) described later, and can be connected to the other side of the electrolytic cell (200).

[0134] For example, the second valve module (300) can be connected to the downstream side of the electrolytic cell (200) as the first electrolytic water path and the second electrolytic water path, which will be described later, are connected to the outlet of the first electrode chamber (210) and the outlet of the second electrode chamber (220).

[0135] The electrolytic cell (200) and the second valve module (300) can be directly connected.

[0136] That is, the second valve module (300) can be integrated with the electrolytic cell (200) by being combined in such a way that the third fastening member (311a) and the fourth fastening member (312a), which will be described later, are mounted corresponding to the outlet of the first electrode chamber (210) and the outlet of the second electrode chamber (220).

[0137] However, the electrolytic cell (200) and the second valve module (300) may be indirectly connected through a separate medium as needed.

[0138] The second valve module (300) can receive electrolyzed water from the electrolytic cell (200).

[0139] The second valve module (300) may be configured to be connected to the downstream side of the electrolytic cell (200) to selectively control the flow of electrolytic water generated and provided from the electrolytic cell (200).

[0140] For example, the second valve module (300) may have multiple flow paths inside, and may receive the first electrolytic water through one of the multiple flow paths and receive the second electrolytic water through another flow path, and may selectively switch the flow paths so that the first electrolytic water and the second electrolytic water flow through one of the remaining flow paths and the other.

[0141] The second valve module (300) will be explained in more detail later.

[0142] Referring to FIGS. 2 and 3, the electrolytic water generating device may include an outlet line (L2).

[0143] The discharge line (L2) may be a line for discharging the first electrolytic water or the second electrolytic water, which is alkaline ionized water generated in the electrolytic cell (200) and flowing through the second valve module (300), to the outside for drinking or use.

[0144] The discharge line (L2) can be provided with a tube or hose through which fluid can flow.

[0145] The water outlet line (L2) can be connected to the second valve module (300) at its upstream side.

[0146] The discharge line (L2) is connected to a discharge means such as a faucet on the downstream side, and can guide the first electrolytic water or the second electrolytic water flowing through the discharge line (L2) to be discharged to the said discharge means.

[0147] The first electrolytic water or the second electrolytic water flowing into the outlet line (L2) through the second valve module (300) may be alkaline ionized water.

[0148] That is, the first electrolytic water generated as alkaline ionized water in the first electrode chamber (210), which is basically provided as a cathode chamber, can be guided to the water outlet line (L2) through the second valve module (300).

[0149] Additionally, when polarity switching occurs between the first electrode (211) of the first electrode chamber (210) and the second electrode (221) of the second electrode chamber (220), the voltage applied to the second electrode (221) of the second electrode chamber (220) becomes negative, and as a result, the second electrode chamber (220) is changed to a negative electrode chamber, so the second electrolytic water generated as alkaline ion water in the second electrode chamber (220) can be guided to the water outlet line (L2) through the second valve module (300).

[0150] Referring to FIGS. 2 and 3, the electrolytic water generating device may include a drainage line (L3).

[0151] The drainage line (L3) may be a line for draining the first electrolytic water or the second electrolytic water, which is acidic ion water generated in the electrolytic cell (200) and flowing through the second valve module (300), to the outside.

[0152] The drainage line (L3) can be provided with a tube or hose through which fluid can flow.

[0153] The drainage line (L3) can be connected to the second valve module (300) at its upstream side.

[0154] The drainage line (L3) may be connected to a drain on the downstream side or to a separate drainage means to guide the first electrolytic water or the second electrolytic water flowing through the drainage line (L3) to be drained to the drain or drainage means.

[0155] The first electrolytic water or the second electrolytic water flowing into the drainage line (L3) through the second valve module (300) may be acidic ionized water.

[0156] That is, the second electrolytic water generated from acidic ionized water in the second electrode chamber (220), which is basically provided as an anode chamber, can be guided to the drainage line (L3) through the second valve module (300).

[0157] Additionally, when polarity switching occurs between the first electrode (211) of the first electrode chamber (210) and the second electrode (221) of the second electrode chamber (220), the voltage applied to the first electrode (211) of the first electrode chamber (210) becomes positive, and as a result, the first electrode chamber (210) is changed to a positive electrode chamber, so the first electrolytic water generated as acidic ion water in the first electrode chamber (210) can be guided to the drainage line (L3) through the second valve module (300).

[0158] Although not shown, a filter (not shown) may be installed on at least one of the inlet line (L1) and the outlet line (L2).

[0159] For example, the filter can be installed on the inlet line (L1) and filtered to purify the supply water guided by the inlet line (L1), thereby making it purified, and the supply water provided from the inlet line (L1) to the first valve module (100) can be purified.

[0160] Accordingly, the supply water supplied to the first valve module (100) or the bypass line (L4) by the inlet line (L1) may refer to a purified water, and the supply water may be understood in this way in the following description as well.

[0161] Referring to FIGS. 2 and 3, the electrolytic water generating device may include a bypass line (L4).

[0162] The bypass line (L4) may be a line that allows the supply water, which flows into the inlet line (L1) and is supplied to the first valve module (100), to selectively bypass the electrolytic cell (200) and flow into the outlet line.

[0163] At this time, the supply water provided to the first valve module (100) may be purified water that has been filtered and purified by the filter as described above, and the bypass line (L4) may be a purified water line that guides such purified water.

[0164] The bypass line (L4) can be provided as a tube or hose through which fluid can flow.

[0165] The bypass line (L4) can be connected upstream to the first valve module (100).

[0166] For example, the upstream side of the bypass line (L4) can be connected to the bypass path to be described later of the first valve module (100).

[0167] The bypass line (L4) can be connected to the discharge line (L2) at its downstream end.

[0168] In the case where the supply water itself, preferably purified water purified through filtration of the supply water, must be discharged through the discharge means without electrolysis of the supply water provided from the inlet line (L1), the supply water or purified water can be discharged through the discharge means without passing through the interior of the electrolytic cell (200) by being guided to the bypass line (L4) and the discharge line (L2) through the bypass path of the first valve module (100).

[0169] Accordingly, the electrolytic water generating device allows the supply water to pass through the inside of the electrolytic cell (200) only when electrolysis of the supply water is required, and bypasses the electrolytic cell (200) when the supply water itself is simply discharged, that is, when purified water is discharged. By blocking the unnecessary flow of purified water inside the electrolytic cell (200), it is possible to prevent the lifespan of the electrolytic cell (200) and each component forming the electrolytic cell (200) from being shortened in advance, and also to suppress the occurrence of scale inside the electrolytic cell (200).

[0170] Referring to FIGS. 2 and 3, the electrolytic water generating device may include a washing line (L5).

[0171] The cleaning line (L5) may be a line connecting the first valve module (100) and the second valve module (300) to remove scale that may occur inside the second valve module (300), the water outlet line (L2), and the water outlet means.

[0172] The cleaning line (L5) can be provided with a tube or hose through which fluid can flow.

[0173] The washing line (L5) can be connected to the first valve module (100) at its upstream side.

[0174] For example, the upstream side of the washing line (L5) can be connected to the washing line guide path described later of the first valve module (100).

[0175] The washing line (L5) can be connected to the second valve module (300) at its downstream side.

[0176] For example, the downstream side of the washing line (L5) can be connected to the washing water inflow path of the second valve module (300), which will be described later.

[0177] The supply water flowing into the first valve module (100) can optionally be supplied to the washing line through the washing line guide path of the first valve module (100).

[0178] A washing material storage tank (400) may be installed on the washing line (L5).

[0179] The cleaning material storage tank (400) can store cleaning material.

[0180] The cleaning material stored in the cleaning material storage tank (400) may be citric acid or water in which citric acid is dissolved.

[0181] The cleaning material stored in the cleaning material storage tank (400) can be dissolved or mixed in the supply water flowing through the cleaning line (L5) which is selectively introduced from the first valve module (100) during the cleaning operation of the electrolytic water generating device, and as a result, the supply water can become acidic cleaning water.

[0182] Such washing water flows along the washing line (L5) and is discharged through the second valve module (300), the water outlet line (L2), and the water outlet means, thereby removing scale that may occur inside the second valve module (300), the water outlet line (L2), and the water outlet means.

[0183] The cleaning operation of the electrolytic water generator can be performed manually or automatically.

[0184] For example, when the output amount of alkaline ionized water from the electrolytic water generator reaches a certain amount, an alert sound requesting a cleaning operation may be sounded or an alert indicator may be displayed on the screen, and the user may proceed with the cleaning operation by pressing a cleaning icon or a cleaning button upon recognizing this. Alternatively, the electrolytic water generator may be controlled so that the cleaning operation proceeds automatically when the output amount of alkaline ionized water from the electrolytic water generator reaches a certain amount.

[0185] In addition, when the operating time of the electrolytic water generator reaches a certain time, an alert sound requesting a cleaning operation may be sounded or an alert indicator may be displayed on the screen, and the user may proceed with the cleaning operation by pressing a cleaning icon or a cleaning button upon recognizing this. Alternatively, the electrolytic water generator may be controlled so that the cleaning operation proceeds automatically when the operating time of the electrolytic water generator reaches a certain time.

[0186] Meanwhile, below, the first valve module (100) and the second valve module (300) will be described in more detail with reference to the drawings.

[0187] As illustrated in FIGS. 2 to 6, the first valve module (100) may be configured to control the flow of supply water provided through the inlet line (L1) and regulate the flow rate, as previously described, by forming a plurality of flow paths.

[0188] For example, the first valve module (100) may include five flow paths internally, and at least two of the five flow paths may be selectively interconnected to guide the supply water supplied from the inlet line (L1) to at least one of the first electrode chamber (210), the second electrode chamber (220), the outlet line (L2), and the washing line.

[0189] The first valve module (100) may include an inlet path.

[0190] The above intake channel may be a channel in which the upstream side is connected to the downstream side of the intake line (L1) so that supply water flows from the intake line (L1) to the first valve module (100).

[0557] At this time, the inner upper surface of the insertion groove on the fifth Euro section (165) side can be pressed against the upper end of the insertion section on the fifth mounting hole (155) side, thereby improving the sealing force of the first disc packing (150).

[0558] A first friction reduction part (166) may be formed on the first fixed disk (160).

[0559] The first friction reduction part (166) may be formed in the shape of a concave groove or a sunken shape on the upper surface of the first fixed disk (160).

[0560] That is, the first friction reduction part (166) can be formed in a stepped state lower than the upper surface of the first fixed disk (160).

[0561] The first friction reduction unit (166) can be provided in multiple numbers.

[0562] For example, the first friction reduction section (166) may be formed with the same size or different sizes between the first flow section (161), the second flow section (162), and the fourth flow section (164), between the first flow section (161), the second flow section (162), and the fifth flow section (165), between the first flow section (161), the third flow section (163), and the fourth flow section (164), and between the first flow section (161), the third flow section (163), and the fifth flow section (165), respectively.

[0563] The first friction reduction part (166) can reduce the frictional force between the first fixed disk (160) and the first rotating disk (170) when the first rotating disk (170), which will be described later, rotates in close contact with the first fixed disk (160).

[0564] The first fixed disk (160), like the first disk packing (150), may have one side of its outer circumference cut off in a planar arc shape to form a vertical surface, and the other side of its outer circumference, which is the opposite side, may have a first rotation prevention part (167) formed by being cut open in a radially outward and vertical direction.

[0566] At this time, the insertion part of the first mounting hole (151) side is inserted into the insertion groove on the first flow path (161) side and can be pressed by the inner upper surface of the insertion groove on the first flow path (161) side, the insertion part of the second mounting hole (152) side is inserted into the insertion groove on the second flow path (162) side and can be pressed by the inner upper surface of the insertion groove on the second flow path (162) side, the insertion part of the third mounting hole (153) side is inserted into the insertion groove on the third flow path (163) side and can be pressed by the inner upper surface of the insertion groove on the third flow path (163) side, the insertion part of the fourth mounting hole (154) side is inserted into the insertion groove on the fourth flow path (164) side and can be pressed by the inner upper surface of the insertion groove on the fourth flow path (164) side, and the insertion groove on the fifth flow path (165) side, The sealing force of the first disc packing (150) for the gap between the first fixed disc (160) and the first disc cover (140) can be further improved by inserting the insertion part on the fifth mounting hole (155) side and pressing it against the inner upper surface of the insertion groove on the fifth Euro part (165) side.

[0567] Additionally, one side of the outer vertical surface of the first fixed disk (160) can be in close contact with the vertical surface of the locking portion of the first disk cover (140) together with the one side of the outer vertical surface of the first disk packing (150), and the other side of the outer vertical surface of the first fixed disk (160) can be fitted from the upper side to the lower side of the locking projection of the first disk cover (140) together with the other side of the outer cut portion of the first disk packing (150).

[0970] At this time, the inner upper surface of the insertion groove on the 9th Euro section (364) side can be pressed against the upper end of the insertion section on the 9th mounting hole (354) side, thereby improving the sealing force of the 2nd disc packing (350).

[0971] In the center of the second fixed disk (360), a tenth Euro section (365) may be formed.

[0972] The 10th Euro section (365) can be formed in the center between the 6th Euro section (361), the 7th Euro section (362), the 8th Euro section (363) and the 9th Euro section (364).

[0973] The 10th Euro section (365) may be a circular hole that penetrates the center of the second fixed disk (360) in an up-and-down direction.

[0974] The 10th Euro section (365) can be connected to the 10th mounting hole (355) while being located directly above the 10th mounting hole (355) when the 2nd fixed disk (360) is installed in the upper position of the 2nd disk packing (350).

[0975] The 10th Euro section (365) can be included in the washing water inflow path as a part of the washing water inflow path.

[0976] That is, the washing water inflow path is configured to include the 10th guide hole (315), 10th through hole (345), and 10th mounting hole (355) described above, as well as the 10th path section (365), so that when selectively connected with the above-mentioned discharge path, it can become a path that guides washing water flowing in from the above-mentioned washing line to the above-mentioned discharge path and discharge line (L2).

[0977] At this time, the washing water flowing into the washing water inflow channel can flow in the order of the 10th guide hole (315), the 10th through hole (345), the 10th mounting hole (355), and the 10th flow channel section (365).

[0978] An insertion groove on the lower surface of the second fixed disk (360) on the 10th Euro section (365) side may be formed.

[0979] The insertion groove on the side of the 10th Euro section (365) can be formed concavely from the lower surface of the second fixed disk (360) upward in the form of a circular groove surrounding the lower circumference of the 10th Euro section (365).

[0980] The depth of the insertion groove on the 10th Euro section (365) side can be formed shorter than the height of the insertion section on the 10th mounting hole (355) side.

[0981] The insertion groove on the side of the 10th Euro section (365) can be formed spaced apart from the 10th Euro section (365), and as a result, the inner surface of the insertion groove on the side of the 10th Euro section (365) can be spaced apart from the inner surface of the 10th Euro section (365).

[0982] The insertion groove on the 10th Euro section (365) corresponds to the insertion part on the 10th mounting hole (355) side, so that when the first fixed disk (160) is installed overlappingly on the upper surface of the second disk packing (350), it can be mutually fitted and coupled with the insertion part on the 10th mounting hole (355) side.

[0983] At this time, the inner upper surface of the insertion groove on the 10th Euro section (365) side can be pressed against the upper end of the insertion section on the 10th mounting hole (355) side, thereby improving the sealing force by the second disc packing (350).

[0984] A second friction reduction part (366) may be formed on the second fixed disk (360).

[0985] The second friction reduction part (366) may be formed in the shape of a concave groove or a sunken shape on the upper surface of the second fixed disk (360).

[0986] That is, the second friction reduction part (366) can be formed in a stepped state lower than the upper surface of the second fixed disk (360).

[0987] The second friction reduction unit (366) may be provided in multiple numbers.

[0988] For example, the second friction reduction section (366) can be formed as a circular shape of equal size between the sixth section (361) and the tenth section (365), and between the seventh section (362) and the tenth section (365), respectively.

[0989] The second friction reduction part (366) can reduce the frictional force between the second fixed disk (360) and the second rotating disk (370) when the second rotating disk (370), which will be described later, rotates in close contact with the second fixed disk (360).

[0990] The second fixed disk (360), like the second disk packing (350), may have one side of its outer circumference cut off in a planar arc shape to form a vertical surface, and a second anti-rotation part (367) may be formed on the other side of its outer circumference, which is the opposite side, by being cut open in a radially outward and vertical direction.

[0991] The second fixed disk (360) can be inserted and installed in the second disk cover (340) so that its lower surface is placed on the upper surface of the second disk packing (350) which is mounted inside the second disk cover (340) and is in close contact with it.

[0992] At this time, the insertion part of the 6th mounting hole (351) side is inserted into the insertion groove on the 6th flow section (361) side and can be pressed by the inner upper surface of the insertion groove on the 6th flow section (361) side, the insertion part of the 7th mounting hole (352) side is inserted into the insertion groove on the 7th flow section (362) side and can be pressed by the inner upper surface of the insertion groove on the 7th flow section (362) side, the insertion part of the 8th mounting hole (353) side is inserted into the insertion groove on the 8th flow section (363) side and can be pressed by the inner upper surface of the insertion groove on the 8th flow section (363) side, the insertion part of the 9th mounting hole (354) side is inserted into the insertion groove on the 9th flow section (364) side and can be pressed by the inner upper surface of the insertion groove on the 9th flow section (364) side, and the insertion groove on the 10th flow section (365) side, The sealing force of the second disc packing (350) in the gap between the second fixed disc (360) and the second disc cover (340) can be further improved by inserting the insertion part on the 10th mounting hole (355) side and pressing it against the inner upper surface of the insertion groove on the 10th Euro part (365) side.

[0993] Additionally, one side of the outer vertical surface of the second fixed disk (360) can be in close contact with the vertical surface of the locking part of the second disk cover (340) together with the one side of the outer vertical surface of the second disk packing (350), and the other side of the outer second rotation prevention part (367) of the second fixed disk (360) can be fitted from the upper side to the lower side to the locking projection of the second disk cover (340) together with the other side of the outer cut of the second disk packing (350).

[0994] As a result, the second fixed disk can be fixedly installed within the second disk cover (340) in a non-rotatable state by being restrained by the locking portion of the second disk cover (340) and the locking projection of the second disk cover (340).

[0995] Referring to FIGS. 9 to 11, the second valve module (300) may include a second rotating disk (370).

[1012] That is, the second connecting part (372) can selectively switch the path to which the first electrolytic water path is connected according to the rotation of the second rotating disk (370).

[1013] On the opposite side of the second connecting part (372), a third connecting part (373) may be formed.

[1019] The third connecting part (373) can selectively connect the seventh fluid passage (362) and the eighth fluid passage (363) formed on the second fixed disk (360) according to the rotation of the second rotating disk (370) by the second driving part (390) to be described later, or selectively connect the seventh fluid passage (362) and the ninth fluid passage (364), and as a result, the second electrolytic water passage and the water outlet passage can be selectively connected, or the second electrolytic water passage and the drainage passage can be selectively connected.

[1020] That is, the third connecting part (373) can selectively switch the path to which the second electrolytic water path is connected according to the rotation of the second rotating disk (370).

[1021] A fourth connecting part (374) may be formed between the second connecting part (372) and the third connecting part (373).

[1022] The fourth connecting part (374) can be formed in the center of the lower surface of the second rotating disk (370).

[1024] The fourth connecting part (374) may include a fourth connecting groove (374a) and a fifth connecting groove (374b).

[1025] The fourth connecting groove (374a) may be a circular groove formed in the center of the lower surface of the second rotating disk (370).

[1026] The fourth communication groove (374a) can always remain in communication with the tenth flow path (365) formed in the second fixed disk (360) regardless of the rotation of the second rotating disk (370).

[1027] A fifth connecting groove (374b) can be connected to one side of the fourth connecting groove (374a).

[1028] The fifth connecting groove (374b) may be a square groove integrally connected to the rear side of the fourth connecting groove (374a).

[1029] The fifth connecting groove (374b) can be connected by overlapping directly above the eighth groove (363b) of the eighth flow section (363) according to the rotation of the second rotating disk (370).

[1030] As a result, the fourth connecting part (374) can be connected to the eighth Euro part (363).

[1031] That is, the fourth connecting part (374) can selectively connect the eighth fluid passage (363) and the tenth fluid passage (365) formed in the second fixed disk (360) according to the rotation of the second rotating disk (370) by the second driving part (390) to be described later, and thereby the washing water inflow passage and the water outflow passage can be selectively connected.

[1032] The second rotating disk (370) is configured as described above and can selectively switch the connection of each flow path formed in the second valve module (300) according to the operating mode of the electrolytic water generating device.

[1033] Referring to FIGS. 8 to 10, the second valve module (300) may include a second bracket (380).

[1034] The second bracket (380) may be configured to connect the second driving unit (390), which will be described later, onto the second valve cover (330).

[1035] The second bracket (380) may have fastening portions formed on both the left and right sides of the outer circumference of the disc.

[1036] The second bracket (380) may have a pair of fastening holes formed in its lower portion to correspond to a pair of fastening bosses of the second valve cover (330).

[1037] A pair of fastening holes of the second bracket (380) can be fastened by screws while being fitted into a pair of fastening bosses of the second valve cover (330), and thereby the second bracket (380) can be fastened and fixed to the second valve cover (330).

[1038] Referring to FIGS. 8 to 10, the second valve module (300) may include a second driving unit (390).

[1039] The second drive unit (390) may be configured to provide rotational force to the second rotating disk (370).

[1040] The second drive unit (390) may be a motor having a second rotation shaft (391) that protrudes downward and rotates.

[1041] In particular, the second drive unit (390) may be a stepping motor or a step motor that rotates at a certain angle according to a pulse signal.

[1042] On both sides of the lower surface of the second drive unit (390), flanges corresponding to the two fastening parts of the second bracket (380) may be formed.

[1043] The second rotation axis (391) may have its upper part formed as a circular axis, and its lower part may be formed as a non-circular axis corresponding to the lower part of the shaft groove formed in the upper body of the second linkage axis (332).

[1044] The second drive unit (390) can be fixedly installed on the upper part of the second bracket (380).

[1045] The second drive unit (390) can be in close contact with the upper surface of the second bracket (380) with the lower second rotation shaft (391) inserted into the shaft groove formed in the upper body of the second linkage shaft (332).

[1046] At this time, the flanges on both sides of the second drive unit (390) can be seated on the upper surface of the fastening portions on both sides of the second bracket (380), and in this state, the flanges on both sides of the second drive unit (390) and the fastening portions on both sides of the first bracket (180) are screw-fastened to each other, so that the first drive unit (190) can be fixedly installed on the first bracket (180).

[1047] As described above, the second valve module (300) is provided including each of the aforementioned components and the combination relationships between each of the components, so that the flow paths can be switched to have different flow directions for the first electrolytic water and the second electrolytic water depending on the electrolytic operation or reverse electrolytic operation of the electrolytic cell (200), and the flow paths can be switched so that only specific flow paths are connected and opened during the cleaning operation of the electrolytic water generating device.

[1048] Additionally, the second valve module (300) may have the same configuration as the first valve module (100), except that the shape of each flow path formed on the second rotating disk (370) and each connecting part formed on the second fixed disk (360) differs from the shape of each flow path formed on the first rotating disk (170) and each connecting part formed on the first fixed disk (160).

[1049] Therefore, the first valve module (100) and the second valve module (300) can be used by replacing only the fixed disk and the rotating disk as needed, so they can be compatible with each other and have excellent occupancy.

[1050] Hereinafter, with reference to the drawings, the operation of the first valve module (100) and the second valve module (300) according to the operating mode of the electrolytic water generating device, that is, the rotational state of the first rotating disk (170) relative to the first fixed disk (160) and the rotational state of the second rotating disk (370) relative to the second fixed disk (360), will be described, and the respective flow paths communicating therewith will also be described together.

[1051] Before explaining, the reference position of the first fixed disk (160) and the first rotating disk (170) may be the state shown in FIG. 7 (a) and (b), and the basic state of the second fixed disk (360) and the second rotating disk (370) may be the state shown in FIG. 11 (a) and (b).

[1052] At this time, the first rotation disk (170) and the second rotation disk (370) at the reference position may be designated as having a rotation angle of 0 degrees detected by the first sensor (131) and the second sensor (331).

[1053] When the electrolytic water generating device is not in operation, the first rotating disk (170) and the second rotating disk (370) can be positioned in a reference position.

[1054] Referring to FIGS. 7, FIGS. 11, and FIGS. 12, the electrolytic water generating device can perform electrolytic operation according to the user's selection.

[1055] When the electrolytic discharge operation is in progress, if the first rotating disk (170) and the second rotating disk (370) are not in a reference position, the electrolytic water generating device may perform the electrolytic discharge operation after returning the first rotating disk (170) and the second rotating disk (370) to a reference position.

[1056] Depending on the operation of the power outage, the first rotating disk (170) can remain in the reference position without the first driving unit (190) being driven, and the second rotating disk (370) can rotate counterclockwise at a certain angle, for example, about 127 degrees, from the reference position by receiving rotational force through the driving of the second driving unit (390).

[1057] Accordingly, the first valve module (100) can be in a state where the first communication groove (172a) of the first communication part (172) is in communication with the first flow path part (161) of the inlet flow path, the second communication groove (172b) of the first communication part (172) is in communication across the second penetration part (162a) of the second flow path part (162) of the first electrode chamber guide flow path, and the third communication groove (172c) of the first communication part (172) is in communication over the rear end of the third groove part (163b) of the third flow path part (163) of the second electrode chamber guide flow path, so that the inlet flow path can be in communication with the first electrode chamber guide flow path and the second electrode chamber guide flow path.

[1058] Additionally, the second valve module (300) can be in a state where the sixth flow path (361) and the eighth flow path (363) are connected by the second connecting part (372), and the seventh flow path (362) and the ninth flow path (364) are connected by the third connecting part (373), so that the first electrolytic water flow path can be connected to the discharge flow path, and the second electrolytic water flow path can be connected to the drainage flow path.

[1059] In this way, the supply water supplied from the inlet line (L1) according to the operation of the first valve module (100) and the second valve module (300) during electrostatic operation flows into the inlet water path and is then guided to the first electrode chamber (210) and the second electrode chamber (220) through the first electrode chamber guide path and the second electrode chamber guide path, and can be electrolyzed into the first electrolytic water, which is alkaline ion water, in the first electrode chamber (210) and the second electrolytic water, which is acidic ion water, in the second electrode chamber (220).

[1060] Afterward, the alkaline ionized water of the first electrode chamber (210) is introduced into the first electrolytic water flow path and then guided to the discharge line (L2) by the discharge flow path, and can be discharged through a discharge means such as a faucet, so that it can be drunk or placed in a separate container for use, and the acidic ionized water of the second electrode chamber (220) is introduced into the second electrolytic water flow path and then guided to the drain line (L3) by the drain flow path and discharged through a drain or collected separately for use.

[1061] The electrolytic water generating device can perform electrolytic operation through such processes. Although it was described above that the first rotating disk (170) is in a reference position during electrolytic operation, the first rotating disk (170) during electrolytic operation may be rotated so that the direct communication range (overlap range) between the second flow path (162) and the second communication groove (172b) and the direct communication range (overlap range) between the third flow path (163) and the third communication groove (172c) change depending on the change in water pressure of the supply water flowing through the inlet line (L1) and supplied to the first valve module (100) or the amount of alkaline ion water and acidic ion water required by the user, etc., by operating the first driving unit (190).

[1062] Referring to FIGS. 7, FIGS. 11 and FIGS. 13, the electrolytic water generating device can perform reverse electrolysis operation according to the user's selection.

[1063] Reverse electrolysis operation can be provided to remove scale generated inside the electrolytic cell (200) of the electrolytic water generating device.

[1064] When reverse electrolysis is performed, if the first rotating disk (170) and the second rotating disk (370) are not in the reference position, the electrolytic water generating device may perform reverse electrolysis after returning the first rotating disk (170) and the second rotating disk (370) to the reference position.

[1065] Depending on the performance of the reverse operation, the first rotating disk (170) can rotate counterclockwise by receiving rotational force from the driving of the first driving unit (190), for example, about 67 degrees, and the second rotating disk (370) can rotate clockwise by receiving rotational force from the driving of the second driving unit (390), for example, about 128 degrees.

[1066] Accordingly, the first valve module (100) can be in a state where the first communication groove (172a) of the first communication part (172) is in communication with the first flow path part (161) of the inlet flow path, and the second communication groove (172b) of the first communication part (172) is in a state where it is in communication over the rear end of the second groove part (162b) of the second flow path part (162) of the first electrode chamber guide flow path, and the third communication groove (172c) of the first communication part (172) is in a state where it is in communication across the third penetration part (163a) of the third flow path part (163) of the second electrode chamber guide flow path, so that the inlet flow path is in communication with the first electrode chamber guide flow path and the second electrode chamber guide flow path.

[1067] Additionally, the second valve module (300) can be in a state where the sixth flow path (361) and the ninth flow path (364) are connected by the second connecting part (372), and the seventh flow path (362) and the eighth flow path (363) are connected by the third connecting part (373), so that the second electrolytic water flow path can be connected to the discharge flow path, and the first electrolytic water flow path can be connected to the drainage flow path.

[1068] That is, when operating in reverse electrolysis, the connection of the flow paths by the rotation of the first rotating disk (170) and the second rotating disk (370) can be formed in a shape approximately symmetrical to that of the electrolytic electrolysis operation described above.

[1069] In this way, the supply water supplied from the inlet line (L1) according to the operation of the first valve module (100) and the second valve module (300) during reverse electrolysis operation flows into the inlet water path and is then guided to the first electrode chamber (210) and the second electrode chamber (220) through the first electrode chamber guide path and the second electrode chamber guide path, and can be electrolyzed into acidic ionized water in the first electrode chamber (210) and alkaline ionized water in the second electrode chamber (220).

[1070] Afterward, the acidic ion water of the first electrode chamber (210) can be introduced into the first electrolytic water path and then guided to the drain line (L3) by the drain path and discharged through a drain, etc., and the alkaline ion water of the second electrode chamber (220) can be introduced into the second electrolytic water path and then guided to the discharge line (L2) by the discharge path and discharged through a discharge means such as a faucet.

[1071] The electrolytic water generator can perform reverse electrolysis operation through these processes.

[1072] Referring to FIGS. 7, FIGS. 11 and FIGS. 14, the electrolytic water generating device can perform water purification operations according to the user's selection.

[1073] Water purification operation can be provided for drinking or using purified water without the electrolysis process of the electrolytic water generator.

[1074] When the first rotating disk (170) and the second rotating disk (370) are not in a reference position during the water purification operation, the electrolytic water generating device may perform the water purification operation after returning the first rotating disk (170) and the second rotating disk (370) to the reference position.

[1075] Depending on the operation of the integer, the first rotating disk (170) can rotate clockwise at a certain angle, for example, about 33 degrees, by receiving rotational force from the driving of the first driving unit (190), and the second rotating disk (370) can rotate counterclockwise at a certain angle, for example, about 180 degrees, by receiving rotational force from the driving of the second driving unit (390).

[1076] Accordingly, the first valve module (100) can be in a state where the first communication groove (172a) of the first communication part (172) is in communication with the first flow path part (161) of the inlet flow path, and the third communication groove (172c) of the first communication part (172) is in communication over the right half of the fourth flow path part (164) of the bypass flow path, so that the inlet flow path is in communication with the bypass flow path.

[1077] Additionally, the second valve module (300) can be in a state where the second connecting part (372) is connected only to the sixth flow path (361), and the third connecting part (373) is connected only to the seventh flow path (362), so that all flow paths of the second valve module (300) can be disconnected from each other.

[1078] In this way, the purified water supplied from the inlet line (L1) according to the operation of the first valve module (100) and the second valve module (300) during purification operation flows into the inlet water path, and then is guided directly to the outlet line (L2) through the bypass path without passing through the electrolytic cell (200) and the second valve module (300), so that it can be discharged through a water outlet means such as a faucet, and thus can be drunk or used by placing it in a separate container, etc.

[1079] The electrolytic water generator can perform water purification operations through such processes.

[1080] Referring to FIGS. 7, FIGS. 11 and FIGS. 14, the electrolytic water generating device can perform a cleaning operation according to the user's selection.

[1081] A cleaning operation may be provided to remove scale generated inside the second valve module (300) of the electrolytic water generating device, the water outlet line (L2), and the water outlet means such as the faucet.

[1082] When the first rotating disk (170) and the second rotating disk (370) are not in a reference position during the cleaning operation, the electrolytic water generating device may perform the cleaning operation after returning the first rotating disk (170) and the second rotating disk (370) to the reference position.

[1083] Depending on the performance of the cleaning operation, the first rotating disk (170) can rotate counterclockwise at a certain angle, for example, approximately 213 degrees, by receiving rotational force from the driving of the first driving unit (190), and the second rotating disk (370) can remain in the reference position as the second driving unit (390) is not driven.

[1084] Accordingly, the first valve module (100) may be in a state where the first communication groove (172a) of the first communication section (172) is in communication with the first flow path section (161) of the inlet flow path, and the second communication groove (172b) of the first communication section (172) may be in a state where it is in communication over the rear end of the fifth groove section (165b) of the fifth flow path section (165) of the washing line guide flow path.

[1085] Additionally, the second valve module (300) can be in a state where the eighth flow path (363) and the tenth flow path (365) are connected by the fourth connecting part (374).

[1086] In this way, the supply water supplied from the inlet line (L1) according to the operation of the first valve module (100) and the second valve module (300) during the cleaning operation can be guided to the cleaning line (L5) through the cleaning line guide path after flowing into the inlet water path.

[1087] At this time, citric acid provided from a washing material storage tank (400) installed on the washing line (L5) may be dissolved in the supply water guided to the washing line (L5), and as a result, the supply water guided to the washing line (L5) may become washing water that is somewhat acidic.

[1088] Subsequently, the washing water of the washing line (L5) flows into the washing water inlet path to remove scale within the second valve module (300), that is, scale in the outlet path, and is guided to the outlet line (L2) to remove scale formed in the outlet line (L2) and the outlet means such as the faucet, and is discharged to the outside, thereby having improved performance compared to conventional technologies that could only remove scale of the electrolytic cell (200) through polarity switching.

[1089] The electrolytic water generator can perform cleaning operations through such processes.

[1090] Hereinafter, an electrolytic water generating device according to another embodiment of the present invention is described. Since each component of the electrolytic water generating device according to another embodiment of the present invention, excluding the electrolytic cell, is applied in the same way as each component of the electrolytic water generating device according to one embodiment of the present invention, the description thereof is omitted and reference is made to the aforementioned contents.

[1092] FIG. 17 is a perspective view illustrating an electrolytic water generating device according to another embodiment of the present invention.

[1093] As illustrated in FIGS. 16 to 17, an electrolytic water generating device according to another embodiment of the present invention may be provided with a plurality of electrolytic cells (200, 200') to improve performance.

[1094] For example, the electrolytic cell (200, 200') may be provided in two, such as an upstream electrolytic cell (200) and a downstream electrolytic cell (200').

[1095] The upstream electrolytic cell (200) may have an electrolytic chamber (200a) formed inside, and a diaphragm (230) may be placed inside the electrolytic chamber (200a). The electrolytic chamber (200a) may be divided into a first electrode chamber (210) and a second electrode chamber (220) on both sides based on the diaphragm (230), and a first electrode (211) may be installed in the first electrode chamber (210) and a second electrode (221) may be installed in the second electrode chamber (220).

[1096] Additionally, the downstream electrolytic cell (200') may also have an electrolytic chamber (200a') formed inside, and a diaphragm (230') may be placed inside the electrolytic chamber (200a'). The electrolytic chamber (200a') may be divided into a first electrode chamber (210') and a second electrode chamber (220') on both sides based on the diaphragm (230'), and a first electrode (211') may be installed in the first electrode chamber (210') and a second electrode (221') may be installed in the second electrode chamber (220').

[1097] The electrolysis process by the upstream electrolytic cell (200) and the downstream electrolytic cell (200') is omitted from the description, with reference to the aforementioned content and prior art.

[1098] The upstream electrolytic cell (200) and the downstream electrolytic cell (200') can be directly joined and connected in an integrated state so that their opposing surfaces are in close contact with each other.

[1099] At this time, the outlet of the first electrode chamber (210) and the outlet of the second electrode chamber (220) of the upstream electrolytic cell (200) can be connected to the inlet of the first electrode chamber (210') and the inlet of the second electrode chamber (220') of the corresponding downstream electrolytic cell (220'), respectively.

[1100] However, the upstream electrolytic cell (200) and the downstream electrolytic cell (200') may be connected to each other via a separate line as needed.

[1101] In another embodiment of the present invention, the electrolytic water generating device may have a first valve module (100) connected to the inlet of the first electrode chamber (210) and the inlet of the second electrode chamber (220) of the upstream electrolytic cell (200), and a second valve module (300) connected to the outlet of the first electrode chamber (210') and the outlet of the second electrode chamber (220') of the downstream electrolytic cell (200').

[1102] In another embodiment of the present invention, an electrolytic water generating device may have an inlet line (L1) connected to the upstream side of a first valve module (100), an outlet line (L2) and a drainage line (L3) each connected to the downstream side of a downstream electrolytic tank (200'), a bypass line (L4) connected between the first valve module (100) and the outlet line (L2) by bypassing the upstream electrolytic tank (200) and the downstream electrolytic tank (200'), and a washing line (L5) connected between the first valve module (100) and the second valve module (300).

[1103] An electrolytic water generating device according to another embodiment of the present invention is configured as described above and can undergo a plurality of electrolysis processes, thereby generating and utilizing electrolytic water containing a large amount of dissolved hydrogen.

[1104] As described above, although the present invention has been explained by limited embodiments and drawings, the present invention is not limited thereto and it is obvious that various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims described below by those skilled in the art to which the present invention belongs.
