Description

  The present invention relates to an electrolyzed water generating apparatus that generates electrolyzed water generated by electrolysis.

  2. Description of the Related Art Conventionally, an electrolyzed water generating apparatus that generates electrolyzed water in which hydrogen is dissolved by electrolysis is known (see, for example, Patent Document 1). In the electrolyzed water generating device disclosed in Patent Document 1, when the electrolyzed water generated in the first electrode chamber is used, the electrolyzed water generated as a secondary in the second electrode chamber is usually discarded. Discarded as sewage as water.

  By the way, when clogging occurs in a water supply path that supplies water to be electrolyzed to the second electrode chamber or a water discharge path that sends electrolyzed water from the second electrode chamber for some reason, the water flow that moves through the second electrode chamber 40B Therefore, gas generated by electrolysis in the second electrode chamber stays in the second electrode chamber. In this case, since water supplied to the surface of the second power feeder is reduced, electrolysis in the electrolysis chamber may be significantly suppressed.

  Further, the water supplied to the first and second electrode chambers has an action of cooling the diaphragm. In such a case, when the water supply channel connected to the second electrode chamber is clogged, the water supply from the water supply channel to the second electrode chamber is stopped. When electrolysis proceeds in this state, the water in the second electrode chamber is gradually consumed, and the water level in the second electrode chamber decreases. As a result, the amount of water supplied to the surface of the diaphragm on the second electrode chamber side decreases, and the diaphragm may be damaged by overheating.

  On the other hand, in the case where the water discharge channel connected to the second pole chamber is clogged, the generated gas will not be discharged from the water discharge channel. The gas fills and eventually the water level in the second electrode chamber decreases. As a result, the water supplied to the surface of the diaphragm on the second electrode chamber side decreases as in the case where the water supply channel is clogged, and the diaphragm may be damaged by overheating. As already mentioned, since the electrolyzed water generated in the second electrode chamber is often discarded, clogging of the water supply channel or the water discharge channel on the second electrode chamber side is difficult for the user to detect, so the problem described above. Tends to occur.

Japanese Patent Laying-Open No. 2015-213868

  The present invention has been devised in view of the actual situation as described above, and provides an electrolyzed water generating device capable of efficiently performing electrolysis in an electrolysis chamber and increasing the dissolved hydrogen concentration while suppressing damage to the diaphragm. The main purpose.

  The electrolyzed water generating apparatus according to the first aspect of the present invention is divided into a first electrode chamber in which a first power feeding body is disposed and a second electrode chamber in which a second power feeding body is disposed, and water is separated by a diaphragm. An electrolysis chamber that generates electrolyzed water by electrolysis, a first water supply channel that is connected to the first electrode chamber and supplies water to be electrolyzed to the first electrode chamber, and is connected to the first electrode chamber And a second water supply channel connected to the second electrode chamber and supplying water to be electrolyzed to the second electrode chamber. And a second water discharge channel that is connected to the second electrode chamber and delivers electrolyzed electrolyzed water from the second electrode chamber, and a water level in the second water discharge channel is provided in the second water discharge channel. A water level detecting means for detecting the above is provided.

  In the electrolyzed water generating apparatus according to the present invention, the water level detection unit detects an light irradiated from the irradiation unit, and light emitted from the irradiation unit and transmitted through the second water discharge channel, and outputs an electric signal. It is desirable to have a light receiving part.

  In the electrolyzed water generating apparatus according to the present invention, the water level detection means further includes a determination means for determining clogging of the second water supply channel and the second water discharge channel based on an electrical signal output from the light receiving unit. It is desirable to provide.

  In the electrolyzed water generating device according to the present invention, it is preferable that the second water discharge channel extends upward from an upper end portion of the second electrode chamber.

  In the electrolyzed water generating apparatus according to the present invention, it is preferable that a water supply restriction unit that restricts water supply to the second electrode chamber is provided in the second water supply channel.

  In the electrolyzed water generating device of the present invention, an electrolysis chamber having a diaphragm, a first electrode chamber and a second electrode chamber, a first water supply channel and a first water discharge channel connected to the first electrode chamber, and a second electrode chamber A connected first water supply channel and a first water supply channel are provided. The gas generated by the electrolysis in the first electrode chamber dissolves in the electrolyzed water, is sent from the first electrode chamber through the first water discharge channel together with the electrolyzed water, and the user can use the electrolyzed water in which the gas is dissolved.

  On the other hand, the gas generated by electrolysis in the second electrode chamber is sent out from the second electrode chamber via the second water discharge channel. If the use of the electrolyzed water generating device is continued in a state where the second water supply channel or the second water discharge channel is clogged, the gas generated in the second electrode chamber will eventually be in the second water discharge channel. It fills up and the water level in the 2nd drainage channel falls. In the present invention, since the water level in the second water discharge channel is detected by the water level detection means provided in the second water discharge channel, the clogging of the second water supply channel or the second water discharge channel can be known. Accordingly, it is possible to efficiently perform the electrolysis in the electrolysis chamber and increase the dissolved hydrogen concentration, while cooling the diaphragm with the electrolyzed water in the second electrode chamber, and to suppress the damage to the diaphragm.

It is a block diagram which shows schematic structure of one Embodiment of the electrolyzed water generating apparatus which concerns on 1st invention of this invention. It is a block diagram which shows the electrical structure of the electrolyzed water generating apparatus of FIG. It is a figure which shows schematic structure of the water level detection means of FIG. It is a figure which shows the signal output from the liquid level sensor of FIG.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of an electrolyzed water generating apparatus 1 according to an embodiment of the present invention. The electrolyzed water generating device 1 generates electrolyzed hydrogen water that is used for drinking or cooking, or used for dialysis treatment. The electrolyzed water generating apparatus 1 includes an electrolyzer 4, a water supply channel 11, and water discharge channels 12 and 13.

  The electrolytic cell 4 generates electrolytic hydrogen water by electrolyzing the supplied water. The electrolytic cell 4 includes an electrolysis chamber 40, a first power feeding body 41, a second power feeding body 42, and a diaphragm 43. The electrolytic chamber 40 is divided by a diaphragm 43 into a first electrode chamber 40A on the first power feeder 41 side and a second electrode chamber 40B on the second power feeder 42 side.

  As the first power supply body 41 and the second power supply body 42, for example, a structure in which a platinum plating layer is formed on the surface of a net-like metal such as an expanded metal made of titanium or the like is applied. Such a net-like first power supply body 41 and second power supply body 42 can distribute water to the surface of the diaphragm 43 while sandwiching the diaphragm 43, and promote electrolysis in the electrolytic chamber 40.

  One of the first power supply 41 and the second power supply 42 is applied as an anode power supply, and the other is applied as a cathode power supply. Water is supplied to both the first electrode chamber 40 </ b> A and the second electrode chamber 40 </ b> B of the electrolysis chamber 40, and a direct current voltage is applied to the first power supply body 41 and the second power supply body 42. Electrolysis occurs.

  For the diaphragm 43, for example, a solid polymer film made of a fluorine-based resin having a sulfonic acid group is appropriately used. On both surfaces of the diaphragm 43, plating layers made of platinum are formed. The plating layer of the diaphragm 43 is in contact with and electrically connected to the first power feeding body 41 and the second power feeding body 42. The diaphragm 43 allows ions generated by electrolysis to pass through. The first power supply body 41 and the second power supply body 42 are electrically connected via the diaphragm 43. When the diaphragm 43 made of a solid polymer material is applied, the dissolved hydrogen concentration can be increased without increasing the pH value of the electrolytic hydrogen water. Such electrolytic hydrogen water is suitable for reducing oxidative stress of patients in dialysis treatment, for example.

  When water is electrolyzed in the electrolysis chamber 40, hydrogen gas and oxygen gas are generated. For example, when the first power supply 41 is applied as a cathode power supply, hydrogen gas is generated in the first electrode chamber 40A, and electrolytic hydrogen water in which the hydrogen gas is dissolved is generated. On the other hand, in the second electrode chamber 40B, oxygen gas is generated, and electrolytic oxygen water in which the oxygen gas is dissolved is generated. When the first power supply body 41 is applied as an anode power supply body, oxygen gas is generated in the first electrode chamber 40A, and electrolytic oxygen water in which the oxygen gas is dissolved is generated. On the other hand, in the second electrode chamber 40B, hydrogen gas is generated, and electrolytic hydrogen water in which the hydrogen gas is dissolved is generated.

  Raw water to be electrolyzed is supplied to the water supply channel 11. A water purification cartridge (not shown) for purifying raw water is appropriately provided upstream of the water supply channel 11.

  The water supply channel 11 branches into a first water supply channel 11 a and a second water supply channel 11 b and is connected to the electrolytic cell 4. The first water supply path 11a is connected to the first pole chamber 40A. The first water supply channel 11a supplies water to be electrolyzed to the first pole chamber 40A. The second water supply channel 11b is connected to the second pole chamber 40B. The second water supply channel 11b supplies water to be electrolyzed to the second pole chamber 40B.

  The first water discharge channel 12 is connected to the first pole chamber 40A. The first water discharge channel 12 delivers the electrolyzed water electrolyzed in the first electrode chamber 40A from the first electrode chamber 40A.

  In the present embodiment, the first water supply channel 11a communicates with the lower end portion of the first pole chamber 40A, and the first water discharge channel 12 communicates with the upper end portion of the first pole chamber 40A. Thereby, a general flow of water is generated from the lower part to the upper part of the first electrode chamber 40A. The gas generated by the electrolysis in the first electrode chamber 40A becomes a fine bubble and moves to the upper part of the first electrode chamber 40A. Therefore, since the gas moving direction and the direction in which water flows in the first pole chamber 40A coincide with each other, the gas easily dissolves in water, and the concentration of dissolved gas is easily increased.

  The second drainage channel 13 is connected to the second pole chamber 40B. The second drainage channel 13 delivers the electrolyzed water electrolyzed in the second electrode chamber 40B from the second electrode chamber 40B.

  In the present embodiment, the second water supply channel 11b communicates with the lower end portion of the second pole chamber 40B, and the second water discharge channel 13 communicates with the upper end portion of the second pole chamber 40B. Thereby, a general flow of water is generated from the lower part to the upper part of the second electrode chamber 40B. The gas generated by electrolysis in the second electrode chamber 40B becomes a fine bubble and moves to the upper part of the second electrode chamber 40B. Therefore, since the gas moving direction and the direction in which water flows generally in the second electrode chamber 40B coincide with each other, the gas is easily sent out from the second electrode chamber 40B. Thereby, it is suppressed that gas stays on the surface of the second power feeding body 42, and sufficient water is supplied to the surface of the second power feeding body 42 to promote electrolysis in the electrolysis chamber 40. The hydrogen concentration is easily increased.

  FIG. 2 shows an electric circuit for supplying an electrolytic current to the power feeding bodies 41 and 42. The electrolytic current I supplied to the power feeding bodies 41 and 42 is controlled by the control unit 6.

  The control unit 6 controls each unit such as the power feeding bodies 41 and 42. The control unit 6 includes, for example, a CPU (Central Processing Unit) that executes various arithmetic processes, information processing, and the like, a program that controls the operation of the CPU, and a memory that stores various information.

  For example, the control unit 6 controls the polarities of the first power feeding body 41 and the second power feeding body 42. When the control unit 6 changes the polarities of the first power supply body 41 and the second power supply body 42 to each other, desired electrolyzed water out of the electrolyzed hydrogen water or the electrolyzed oxygen water is supplied from the first electrode chamber 40A to the first water outlet 12 and is available for use.

  Hereinafter, the case where the first power feeding body 41 is applied as a cathode power feeding body will be described unless otherwise specified, but the same applies to the case where the first power feeding body 41 is applied as an anode power feeding body.

  A current detection means 44 is provided on the current supply line between the first power feeder 41 and the control unit 6. The current detection unit 44 may be provided in a current supply line between the second power feeder 42 and the control unit 6. The current detection unit 44 detects the electrolytic current I supplied to the power feeding bodies 41 and 42 and outputs an electric signal corresponding to the value to the control unit 6.

  For example, the control unit 6 controls the DC voltage applied to the first power supply body 41 and the second power supply body 42 based on the electrical signal output from the current detection means 44. More specifically, the control unit 6 controls the first power supply body 41 and the second power supply body 41 so that the electrolysis current I detected by the current detection unit 44 becomes a desired value according to the preset dissolved hydrogen concentration. The DC voltage applied to the power feeding body 42 is feedback controlled. For example, when the electrolysis current I is excessive, the control unit 6 decreases the voltage, and when the electrolysis current I is excessive, the control unit 6 increases the voltage. Thereby, the electrolysis current I supplied to the 1st electric power feeder 41 and the 2nd electric power feeder 42 is controlled appropriately.

  The second water supply passage 11b is provided with a water supply restriction means 25 for restricting water supply to the second pole chamber 40B. In the present embodiment, for example, a flow control valve is applied as the water supply restriction unit 25. The water supply restriction means 25 may be configured by the second water supply passage 11b in which a part or the whole flow passage cross-sectional area is set to be small. By providing the water supply restricting means 25 in the second water supply path 11b, it is possible to reduce the electrolyzed water generated secondary in the second electrode chamber 40B and to effectively use the water. When water supply to the second electrode chamber 40B is remarkably limited by the water supply restricting means 25, a part of the oxygen gas O generated in the second electrode chamber 40B becomes electrolyzed water in the second electrode chamber 40B. It is not melted and is sent out from the second water discharge passage 13 together with the electrolyzed water in the form of minute bubbles.

  The second water outlet 13 is provided with a water level detection means 26 for detecting the water level in the second water outlet 13. The water level detection means 26 includes, for example, an optical liquid level sensor 28 (see FIG. 2).

  FIG. 3 shows the liquid level sensor 28. The liquid level sensor 28 includes an irradiation unit 28a that emits light, and a light receiving unit 28b that receives the light emitted from the irradiation unit 28a.

  The irradiation unit 28a is configured by, for example, a light emitting diode. The irradiation unit 28a is controlled by the control unit 6 and irradiates infrared light toward the light receiving unit 28b. The light receiving unit 28b is configured by, for example, a light receiving element such as a photodetector. The light receiving unit 28 b photoelectrically converts the infrared light transmitted through the second water discharge channel 13 and outputs an electrical signal corresponding to the value to the control unit 6. The liquid level sensor 28 is disposed so that the second water discharge channel 13 is positioned in the optical path between the irradiation unit 28a and the light receiving unit 28b. The second water discharge channel 13 has translucency at least at a location where the liquid level sensor 28 faces.

  FIG. 3A shows that the water level in the second water discharge channel 13 is lower than the detection region of the liquid level sensor 28 (that is, in the second water discharge channel 13 corresponding to the detection region of the liquid level sensor 28). FIG. 3B shows a case where the water level in the second water discharge channel 13 is higher than the detection region of the liquid level sensor 28 (that is, the second corresponding to the detection region of the liquid level sensor 28). This shows a case where the water outlet 13 is filled with water.

  As shown in FIG. 3A, when the water level in the second water discharge channel 13 is lower than the detection area of the liquid level sensor 28, the light emitted from the irradiation unit 28a is the second water discharge channel. The light is refracted on the inner surface of 13 and is incident on the light receiving portion 28b and detected. In this case, a signal (high signal) indicating that light has been received is output from the light receiving unit 28 b to the control unit 6.

  On the other hand, as shown in FIG. 3B, when the water level in the second water discharge channel 13 is higher than the detection area of the liquid level sensor 28, the light emitted from the irradiation unit 28 a is the second water discharge channel 13. As a result, it does not enter the light receiving portion 28b and is not detected. In this case, a signal (low signal) indicating that light has not been received is output from the light receiving unit 28 b to the control unit 6.

  The controller 6 controls the operation of the electrolytic cell 4 based on the electrical signal output from the light receiver 28b. For example, when the water level in the second water discharge channel 13 is lower than the detection region of the liquid level sensor 28, the control unit 6 stops supplying the electrolytic current I to the first power supply body 41 and the second power supply body 42. To do. Thereby, the electrolysis in the electrolysis chamber 40 is stopped, further lowering of the water level in the second water discharge channel 13 is suppressed, and damage to the diaphragm 43 can be suppressed. When the water level in the 2nd water discharge channel 13 falls rather than the detection area of the liquid level sensor 28, the control part 6 may be comprised so that the warning which urges | checks and repairs the electrolyzed water generating apparatus 1 may be issued. .

  FIG. 4 shows the transition of the signal output from the light receiving unit 28b to the control unit 6. 4A shows that each part of the electrolyzed water generating apparatus 1 is operating normally (that is, electrolyzing water supplied to the electrolyzer 4 to generate electrolyzed hydrogen water and electrolyzed oxygen water). In this case, the signal is output from the light receiving unit 28b. FIG. 4B shows a signal output from the light receiving unit 28b when the second water supply channel 11b or the second water supply channel 13 is clogged.

  During normal operation, oxygen gas generated by electrolysis in the second electrode chamber 40B is sent from the second electrode chamber 40B on a water stream that moves through the second electrode chamber 40B while maintaining a small bubble state. It passes through the detection area of the liquid level sensor 28. As shown in FIG. 3B, when the second water outlet 13 is filled with water, the light receiving unit 28b outputs an output of a low signal L1 indicating that light has not been received. The light receiving unit 28b that has detected the bubble outputs a high signal H1 having a small width. For this reason, during normal operation, as shown in FIG. 4A, a pulse signal P1 having a small width is output randomly and frequently. Such a signal is the pulse signal P1 during normal operation.

  On the other hand, at the time of abnormal operation in which the second water supply passage 11b is clogged, the water flow that moves through the second electrode chamber 40B disappears, so that oxygen gas generated by electrolysis stays in the second electrode chamber 40B. For this reason, the detection area of the liquid level sensor 28 is not filled with small bubbles but is still filled with water. As shown in FIG. 4B, the light signal from the light receiving unit 28b is a low signal L2. Is output continuously. When oxygen gas bubbles staying in the second electrode chamber 40B grow in a lump shape, the bubbles move upward from the second electrode chamber 40B by buoyancy and pass through the detection region of the liquid level sensor 28. At this time, as shown in FIG. 4 (b), a pulse signal P2 based on a high signal H2 having a large width is output from the light receiving unit 28b that has detected a lump of bubbles. Such a signal is the pulse signal P2 at the time of abnormal operation.

  When clogging occurs in the second water supply channel 11b connected to the second electrode chamber, the water supply from the second water supply channel 11b to the second electrode chamber 40B is stopped. When the electrolysis proceeds in this state, the water in the second electrode chamber 40B is gradually consumed, and the water level in the second outlet channel 13 is lowered as the above-mentioned bubbles of the massive oxygen gas move upward. As a result, when the water level falls to the detection region of the liquid level sensor 28, as shown in FIG. 4B, the high signal H3 is continuously output from the light receiving unit 28b.

  On the other hand, even when the second water discharge channel 13 is clogged, the generated gas is no longer discharged from the second water discharge channel 13, so that oxygen gas eventually flows from the clogged portion of the second water discharge channel 13 to the second electrode chamber 40B. As a result, the water level in the second electrode chamber 40B decreases. As a result, the signal shown in FIG. 4B is output as in the case where the second water supply channel 11b is clogged.

  Therefore, the control unit 6 can detect clogging of the second water supply passage 11b and the second water discharge passage 13 by monitoring a signal output from the liquid level sensor 28. That is, the control unit 6 has a function as a determination unit that determines whether the second water supply channel 11b and the second water supply channel 13 are clogged.

  For example, the control unit 6 counts the number of pulses output from the liquid level sensor 28 during a predetermined time T (see FIGS. 4A and 4B), and sets a predetermined first threshold value. Compare. As a result, as shown in FIG. 4A, when the number of pulses is larger than the first threshold, it is possible to determine that the state of the electrolytic cell 4, the second water supply channel 11b, and the second water discharge channel 13 is normal. . On the other hand, as shown in FIG. 4B, when the number of pulses is smaller than the first threshold value, it is possible to determine that the state of the electrolytic cell 4, the second water supply channel 11b, and the second water discharge channel 13 is abnormal ( First method).

  Further, the control unit 6 calculates the width w (see FIGS. 4A and 4B) of the pulse output from the liquid level sensor 28 and compares it with a predetermined second threshold value. As a result, as shown in FIG. 4A, when the pulse width w is smaller than the second threshold value, it is determined that the state of the electrolytic cell 4, the second water supply channel 11b, and the second water discharge channel 13 is normal. it can. On the other hand, as shown in FIG. 4B, when the pulse width w is larger than the second threshold value, it is possible to determine that the state of the electrolytic cell 4, the second water supply channel 11b, and the second water discharge channel 13 is abnormal. (Second method).

  By using the first method or the second method, the control unit 6 uses the second water supply channel 11b or the second water discharge channel before the water level in the second water discharge channel 13 decreases to the detection area of the liquid level sensor 28. 13 abnormalities can be detected. The control unit 6 may determine whether the second water supply channel 11b and the second water discharge channel 13 are clogged by combining the first method and the second method. In this case, it becomes possible to determine the clogging of the second water supply channel 11b and the second water supply channel 13 more accurately.

  In the present invention, since the water level in the second water discharge channel 13 is detected by the water level detection means 26 provided in the second water discharge channel 13, the clogging of the second water supply channel 11b or the second water discharge channel 13 is known. Can be done. Accordingly, it is possible to efficiently perform the electrolysis in the electrolytic chamber 40 and increase the dissolved hydrogen concentration, while cooling the diaphragm 43 with the electrolytic water in the second electrode chamber 40B, and to suppress the damage of the diaphragm 43. In this embodiment, since water more than the amount of water supply of the 2nd water supply path 11b is supplied from the 1st water supply path 11a to the 1st pole room 40A, it is by electrolyzed water in the 1st pole room 40A and the 2nd pole room 40B. It is possible to cool the entire diaphragm 43 from both sides and further suppress the damage to the diaphragm 43.

  Further, in the optical (non-contact) liquid level sensor 28 that detects the water level in the second water discharge channel 13 by using infrared light transmitted through the second water discharge channel 13, a sensor or the like is arranged in the second water discharge channel 13. Therefore, generation and propagation of germs in the second water discharge channel 13 can be suppressed.

  In addition, in the electrolyzed water generating apparatus 1, the water supply restriction means 25 may be omitted from the second water supply path 11b. In this case, since the amount of water supplied from the second water supply channel 11b to the second electrode chamber 40B increases, the oxygen gas generated in the second electrode chamber 40B is likely to dissolve in the electrolyzed water in the second electrode chamber 40B. As a result, the bubbles of oxygen gas become smaller or all of the oxygen gas dissolves in the electrolyzed water, and the pulse shown in FIG. 4A is obtained from the signal output from the liquid level sensor 28 during normal operation. May not be detected. Even in this case, when the second water supply passage 11b or the second water discharge passage 13 is clogged, the abnormal pulse signal P2 shown in FIG. 4B is detected. Therefore, the control part 6 can detect abnormality of the 2nd water supply channel 11b or the 2nd water discharge channel 13 by using the said 2nd method.

  The second water discharge channel 13 extends upward from the upper end of the second pole chamber 40B. Thereby, when the states of the second water supply channel 11b and the second water discharge channel 13 are normal, the oxygen gas generated by the electrolysis in the second electrode chamber 40B rides on the water flow moving through the second electrode chamber 40B. Thus, it is easy to send out from the second electrode chamber 40B. Accordingly, the normal pulse signal P1 shown in FIG. 4 (a) is easily detected from the signal output from the liquid level sensor 28, and more abnormalities such as clogging of the second water supply passage 11b and the second water discharge passage 13 are further detected. It becomes possible to judge more accurately.

  In addition, when the diaphragm 43 is damaged for some reason, the water in the second polar chamber 40B flows into the second polar chamber 40B, and the water level in the second outlet channel 13 is lowered. In the present embodiment, even when such an abnormality occurs, the liquid level sensor 28 detects that the water level in the second outlet channel 13 has decreased, and the water level reaches the upper end of the second polar chamber 40B. Before the decrease, the control unit 6 stops the operation of the electrolytic cell 4.

  In the electrolyzed water generating apparatus 1, the clogging due to adhesion of the scale or the like of the second water discharge channel 13 connected to the second electrode chamber 40B that is the cathode chamber is detected by applying the first power supply body 41 as the anode power supply body. can do. Such a function is easily realized by the control unit 6 exchanging the polarities of the first power feeding body 41 and the second power feeding body 42 with each other. The detection of clogging due to adhesion of the scale or the like of the second water discharge channel 13 connected to the cathode chamber is particularly effective in a form in which the diaphragm 43 is constituted by, for example, a polytetrafluoroethylene (PTFE) hydrophilic film.

  As mentioned above, although the electrolyzed water generating apparatus 1 of this embodiment was demonstrated in detail, this invention is changed and implemented in various aspects, without being limited to said specific embodiment. That is, the electrolyzed water generating apparatus 1 is divided into at least a first electrode chamber 40A in which the first power feeding body 41 is disposed and a second electrode chamber 40B in which the second power feeding body 42 is disposed by the diaphragm 43, and An electrolysis chamber 40 that generates electrolyzed water by electrolyzing water, a first water supply path 11a that is connected to the first electrode chamber 40A and supplies water to be electrolyzed to the first electrode chamber 40A, and a first electrode Connected to the chamber 40A, the electrolyzed electrolyzed water is sent from the first electrode chamber 40A to the first water outlet 12 and the second electrode chamber 40B, and the electrolyzed water is supplied to the second electrode chamber 40B. The second water supply passage 11b, and the second water discharge passage 13 that is connected to the second electrode chamber 40B and delivers the electrolyzed electrolytic water from the second electrode chamber 40B. It is sufficient if water level detection means 26 for detecting the water level in the two outlet channels 13 is provided. .
