Description

The present invention relates to an electrolytic operation method for a diaphragm membrane electrolytic water generator.

  As a form of diaphragm electrolysis electrolyzed water generator, electrolyzed water that is dilute salt water is electrolyzed in the diaphragm electrolyzer, and each electrolyzed water generated in each electrolyzer of the diaphragm electrolyzer flows out There is a diaphragm electrolysis type electrolyzed water generator of the type to be used (see Patent Documents 1, 2, and 3).

  In the diaphragm electrolysis water generator of this type, if Ca ions, Mg ions, etc. are present in the raw water or salt water that prepares the water to be electrolyzed, there will be a scale caused by Ca ions, Mg ions, etc. during diaphragm membrane electrolysis. A phenomenon that occurs frequently in each electrolysis chamber, particularly in the cathode side electrolysis chamber, adheres to and accumulates in each electrolysis chamber, and also adheres to and accumulates on the water-system pipeline on the downstream side of the electrolysis chamber. If the kale adheres to and accumulates in each electrolysis chamber, the electrolysis efficiency in the electrolysis chamber will be greatly reduced, and if the scale adheres to and accumulates on the water system pipeline on the downstream side of the electrolysis chamber, the water system pipeline will be clogged. Thus, it will adversely affect the outflow of electrolyzed water.

  For this reason, in the diaphragm electrolysis type | formula electrolyzed water generating apparatus of the said form, the countermeasure which removes the scale which generate | occur | produces in each electrolysis chamber is requested | required. In each electrolyzed water generating device proposed in each of the above-mentioned patent documents, a means for removing scale components in the raw water is adopted by interposing a water softener in the raw water supply pipe, and diaphragm electrolysis At the time when the electrolysis operation of the specified time elapses (before the scale is generated), the polarity of the electrodes in each electrolysis chamber is reversed to perform the reverse polarity electrolysis operation, thereby preventing the occurrence of scale in each electrolysis chamber Is adopted.

  Among these means, it is difficult to sufficiently prevent the generation of scale in each electrolysis chamber with the former means for removing scale components by the water softener, and with the latter means for performing reverse polarity electrolysis operation, Since the electrolysis water generated in each electrolysis chamber is different from the positive electrolysis operation, it is necessary to switch the outflow pipes of the respective electrolysis water flowing out to each other. Must be used.

  Therefore, in order to remove the scale generated in each electrolysis chamber by reverse polarity electrolysis operation (cleaning operation), normal electrolysis operation of diaphragm membrane electrolysis is temporarily stopped and water such as tap water is continuously supplied to each electrolysis chamber. In general, an electrolytic operation of reverse polarity is performed and each electrolytically generated water generated by electrolysis is continuously drained.

  By the way, the conventional washing operation (reverse polarity electrolysis operation using water as electrolyzed water) is similar to the normal electrolysis production operation in which water is continuously supplied to each electrolysis chamber of the diaphragm electrolyzer. This is a so-called flowing-water electrolysis operation in which the electrolyzed membrane is supplied and subjected to diaphragm electrolysis in each electrolysis chamber, and each electrolysis water produced in each electrolysis chamber flows out continuously. For this reason, in the reverse polarity cleaning operation, the electrolyzed water is normal water and does not contain an electrolysis auxiliary agent, so that the electrolysis efficiency is poor, and electrolysis with a high cleaning function sufficient to clean the electrolysis chamber is performed. It is difficult to produce the produced water, and a long washing operation is required. Moreover, since the washing operation is a flowing water electrolysis generation operation, the amount of water to be electrolyzed is increased, and since a long-time washing operation is added, the amount of water used is further increased. Become.

  On the other hand, in the reverse polarity cleaning operation, when the reverse polarity electrolytic generation operation employed in Patent Document 2 is employed as a dedicated cleaning operation in order to obtain electrolytically generated water having a high function of cleaning the electrolytic chamber. Since the electrolyzed water is dilute salt water, it is possible to generate electrolyzed water having a high cleaning function for the electrolysis chamber. However, since the washing operation is also a flowing water type washing operation, diluted salt water that is more expensive than water is used. The amount of use is large, and electrolyzed water is wasted. The main object of the present invention is to address such problems of the cleaning operation.

  The present invention relates to an electrolytic operation method for a diaphragm membrane electrolytic water generator. The electrolyzed water generating apparatus which is subject to electrolysis operation by the present invention electrolyzes water to be electrolyzed, which is dilute salt water, in a diaphragm electrolyzer, and produces each electrolyzed water generated in each electrolyzer of the diaphragm electrolyzer. It is a diaphragm electrolysis type electrolyzed water generating device of the type which makes it flow out.

  Thus, in the first electrolysis operation method according to the present invention, water to be electrolyzed is continuously supplied to each electrolysis chamber of the diaphragm electrolyzer and subjected to diaphragm electrolysis in each electrolysis chamber, and generated in each electrolysis chamber. The electrolyzed water is continuously flowed out, and the water to be electrolyzed retained in each electrolysis chamber is subjected to diaphragm electrolysis for a predetermined time with the polarity of the electrodes reversed. A batch type cleaning operation of reverse polarity is performed in which each electrolytically generated water generated in each electrolytic chamber is flowed out after the passage to wash each electrolytic chamber.

  The second electrolysis operation method according to the present invention is that water to be electrolyzed is continuously supplied to each electrolysis chamber of the diaphragm electrolyzer to conduct electrolysis of the diaphragm in each electrolysis chamber, and is generated in each electrolysis chamber. Electrolytically generated water that continuously flows out each electrolyzed water is operated, and then the electrolyzed water retained in each electrolysis chamber is subjected to diaphragm membrane electrolysis in a state where the polarity of the electrode is reversed, and a predetermined time has elapsed. Later, each electrolytically generated water generated in each electrolysis chamber was discharged to wash each electrolysis chamber, and then a reverse polarity batch type cleaning operation was performed, and then the electrodes remained in each electrolysis chamber with the polarity reversed. And subjecting the electrolyzed water to be subjected to separation membrane electrolysis, and performing a positive batch cleaning operation in which each electrolytically generated water generated in each electrolytic chamber is flowed out after a predetermined time has passed to wash each electrolytic chamber. To do.

  In the electrolytic operation method according to the present invention, in the batch cleaning operation, the time exceeding the set electrolytic current value is integrated, and the cleaning operation is stopped when the loaded time exceeds the set time, During the remaining time until the set time, the electrolytically generated water is not allowed to flow out of each electrolysis chamber, and can remain in each electrolysis chamber.

  Further, in the electrolytic operation method according to the present invention, in the batch cleaning operation, after the electrolytic operation reaches a predetermined time, the electrolytic operation is stopped and each electrolytically generated water is retained in each electrolytic chamber for a predetermined time. It can also be done.

  In the electrolytic operation method according to the present invention, the time of one day is divided into a time zone in which the electrolytic generation operation is performed and a time zone in which the electrolytic generation operation is not performed. It is set so that the operation can be repeated, and the batch cleaning operation is set to be performed in the time zone in which the electrolysis generation operation is not performed, and in the time zone in which the electrolysis generation operation is performed, it is necessary for the repeated electrolysis generation operation. When the set time reaches the set time, the batch cleaning operation can be performed.

  In this case, prior to the batch type cleaning operation, display on the operation panel or the like that the batch type cleaning operation is performed, and if necessary, indicate that the batch type cleaning operation is being performed. can do.

  Further, in this case, the division of the time zone in which the electrolysis generation operation is performed and the time zone in which the electrolysis generation operation is not performed is managed by a 24-hour timer of 24-hour measurement, and the time measured by the 24-hour timer on an operation panel or the like. When the time displayed on the time display unit is different from the current time, the measurement of the 24-hour timer is corrected. The time displayed on the time display unit can be corrected to the current time.

  Further, in the electrolytic operation method according to the present invention, the number and time of the batch-type cleaning operation are determined based on the hardness of the raw water employed, and the reverse is performed depending on the hardness of the raw water for preparing the electrolyzed water. The number of polar batch cleaning operations and the number of positive polarity batch cleaning operations can be set.

  Further, in the electrolytic operation method according to the present invention, prior to the reverse polarity batch type cleaning operation, the reverse polarity flowing water type cleaning operation is performed in a state where the polarity of the electrode during the electrolytic generation operation is reversed. be able to.

  Further, in the electrolytic operation method according to the present invention, when stopping the electrolysis generation operation, first, the application of voltage to the electrode is stopped, a predetermined time is delayed, and a salt water supply pump that supplies salt water is driven, and The supply of raw water can be stopped and the water to be electrolyzed can be retained in each electrolytic chamber of the diaphragm electrolyzer.

  Further, in the electrolytic operation method according to the present invention, when an electrolyzed water generating device including a plurality of pairs of electrolysis chambers formed by a plurality of pairs of electrodes is employed as an object of the electrolytic operation, an electrolytic generation operation, a batch type When starting the cleaning operation, or the electrolytic generation operation and the batch cleaning operation, the number of energized electrodes can be increased stepwise.

  Further, in the electrolytic operation method according to the present invention, as the target of the electrolytic operation, one electrolytically generated water generated by each electrolytically generated water generated in each electrolytic chamber of the diaphragm membrane electrolytic cell is poured out and used, and the other electrolytically generated When an electrolyzed water generating device is used that drains water without using it, each electrolyzed water generated in a batch-type cleaning operation is used in addition to the extraction pipe that pours one electrolyzed water. It is possible to provide a drain pipe for discharging the water.

  In addition, in the electrolytic operation method according to the present invention, when an electrolyzed water generating device that prepares electrolyzed water by supplying salt water of a predetermined concentration to raw water as an object of electrolytic operation, electrolytic generation is performed. During operation, if the number of supply strokes of the salt water pump greatly increases compared to the number of strokes at the initial setting, the amount of scale generated in the diaphragm electrolyzer has reached the limit, and the cleaning operation is displayed. If necessary, the electrolytic generation operation can be stopped.

  Further, in the electrolytic operation method according to the present invention, raw water supply pipes for introducing raw water for preparing water to be electrolyzed and raw water for diluting and preparing one electrolytically generated water that has been electrolytically generated are introduced as targets for electrolytic operation. When the electrolyzed water generating apparatus including the dilution water supply pipe is employed, a small water softener can be interposed in the raw water supply pipe.

The main pipeline 34 includes a pair of branch pipeline sections 34 a and 34 b that are branched from each other in the middle of the main pipeline 34. A water supply valve 35a is interposed upstream from the branch portion.

  In the raw water supply mechanism 30B, one branch pipe 34a of the branch pipe section is configured as a raw water supply pipe section 34a that supplies raw water for preparing electrolyzed water, and the other of the branch pipe sections. The branch pipe line 34b is configured as a dilution water supply pipe part 34b for supplying dilution water for diluting the electrolytically generated water. The raw water supply pipe part 34 a is connected to a part upstream of the branch part of the electrolyzed water supply pipe 31, and raw water for preparing the electrolyzed water is supplied to the salt water of the electrolyzed water supply pipe 33. It is configured to be. The raw water supplied to the electrolyzed water supply pipe 33 through the raw water supply pipe part 34a dilutes the salt water continuously supplied to the electrolyzed water supply pipe 33 to prepare electrolyzed water having a predetermined concentration. .

  In the electrolysis operation of the electrolyzed water generation apparatus, a flowing water electrolysis generation operation for performing normal diaphragm membrane electrolysis and a reverse polarity batch type cleaning operation for cleaning each electrolytic chamber, or a reverse polarity batch type cleaning operation and positive polarity It has a batch-type cleaning operation. In the reverse polarity batch-type cleaning operation, each electrolysis water generated in each electrolysis chamber dissolves and removes the scale that adheres to and accumulates in each electrolysis chamber and its downstream side pipe, and each outflow pipe 32a. Each of the electrolyzed water that has flowed out to 32b is drained.

  In the electrolyzed water generating apparatus, the electrolytically generated water that flows out to the outflow pipe 32a by switching the three-way switching valve 36a interposed in the middle of the outflow pipe 32a of one of the electrolyzed water (electrolytically generated acidic water). Alkaline water is drained from the drain port of the drain line 36b. In addition, the electrolytically generated acidic water flowing out to the outflow pipe 32b is drained from the drain port of the outflow pipe 32b in the same manner as the electrolytically generated alkaline water generated during the electrolytic generation operation.

  The electrolysis operation method according to the present invention for electrolyzing the electrolyzed water generation apparatus is basically a batch cleaning operation having a reverse polarity to the flowing water electrolysis generation operation, or a batch type having a reverse polarity to the flowing water electrolysis generation operation. This is a method comprising a cleaning operation and a positive polarity batch cleaning operation.

  The electrolysis operation according to the present invention is started by the opening operation of the water supply valve 35a interposed in the main pipe 34 of the raw water supply pipe of the raw water supply mechanism 30B, and the raw water is supplied to the diaphragm electrolyzer through the raw water supply pipe 34a. While being supplied to the D side, salt water is supplied from the salt water tank E to the raw water supply pipe line 34 a through the salt water supply pipe 33 by driving the salt water pump F. As a result, salt water is supplied to the raw water flowing in the raw water supply pipe section 34a to prepare electrolyzed water that is a diluted salt water having a predetermined concentration, and the prepared electrolyzed water is supplied to each electrolyzed water supply pipe. Through 31a and 31b, it flows into each electrolysis chamber of the diaphragm electrolyzer D and undergoes diaphragm electrolysis.

  Among each electrolytic chamber, electrolytically generated acidic water is generated in the anode-side electrolytic chamber, and synchronously, electrolytically generated alkaline water is generated in the cathode-side electrolytic chamber. The generated electrolytically generated acidic water flows into the dilution water supply pipe section 34b through the outflow pipe 32a, is diluted with raw water flowing through the dilution water supply pipe section 34b, and is diluted to a predetermined concentration. The generated acidic water is poured out from the spout 34c. On the other hand, the electrolytically generated alkaline water generated in the cathode side electrolysis chamber is not intended to be used in the electrolytic water generating apparatus, and is thus drained through the outflow pipe 32b. In the present invention, the above diaphragm membrane electrolysis is referred to as flowing water type electrolysis production operation.

  In the electrolytic operation method according to the present invention, a batch type electrolytic operation with a reverse polarity is performed to remove the scale deposited and deposited on the electrolytic chamber and the downstream water line in the electrolytic generation operation described above, and if necessary, the positive electrode A batch type electrolytic operation is performed. In the present invention, the batch type electrolytic operation is referred to as a batch type cleaning operation.

  In starting the reverse polarity batch type cleaning operation, the electrolyzed water is retained in each electrolysis chamber, and the electrolysis operation is started with the reverse polarity obtained by inverting the polarity of the electrode during the electrolysis generation operation. In the reverse polarity batch cleaning operation, the electrolytic chamber on the anode side is converted into the electrolytic chamber on the cathode side and the electrolytic chamber on the cathode side is converted into the electrolytic chamber on the anode side during the electrolysis generation operation. Electrolytically generated alkaline water is generated in the electrolysis chamber, and synchronously generated acidic water is generated synchronously in the electrolysis chamber that was the electrolysis chamber on the cathode side. Each of the electrolyzed water produced is of a batch type and has high electrolysis efficiency. Therefore, the electrolyzed water has a high removal function against the scale in a short time and without wasting much electrolyzed water. Water is produced.

  The electrolyzed water having a high removal function with respect to the scale dissolves and removes the scale deposited and deposited in the electrolysis chamber and the subsequent outflow pipes 32a and 32b, and cleans these parts. The electrolytically generated alkaline water that has flowed out to the outflow pipe 32a is drained through the discharge port of the drainage pipe 36b, and the degenerated acidic water that has flowed out to the outflow pipe 32b is drained through the drainage of the outflow pipe 36b.

  In this electrolytic operation method, after the reverse polarity batch cleaning operation is completed, a positive polarity batch cleaning operation in which the polarity of the electrode is reversed can be further added. As a result, both the electrolytic chambers and the outflow pipes 32a, 32b and the like on the downstream side can be more accurately washed.

  In the above-described reverse polarity batch-type cleaning operation and positive polarity batch-type cleaning operation, after the batch-type electrolysis is performed for a predetermined time, the state in which the electrolyzed water in the electrolytic chamber is retained is maintained for a predetermined time. Also good.

  FIG. 7 shows an embodiment of a batch cleaning operation in the electrolytic operation method according to the present invention. The batch type cleaning operation employs an embodiment in which a reverse polarity batch type cleaning operation is first performed, and then a positive polarity batch type cleaning operation is performed. Depending on the hardness of the raw water used, the reverse polarity batch type cleaning operation is performed. The operation is repeated a plurality of times, and the positive batch cleaning operation is performed a plurality of times.

  When starting the reverse polarity cleaning operation, the polarity of the electrode is reversed and the supply of the electrolyzed water to each electrolysis chamber is stopped and the electrolyzed water stays in each electrolysis chamber. Energize the chamber electrode and perform reverse polarity batch cleaning operation. When the reverse polarity batch-type cleaning operation elapses for a predetermined time, each electrolytically generated water generated in each electrolysis chamber is discharged, and the reverse polarity batch-type cleaning operation is completed. Subsequently, a positive batch cleaning operation is performed.

  When starting a positive batch cleaning operation, the polarity of the electrode is reversed, the supply of the electrolyzed water to each electrolysis chamber is stopped, and the electrolyzed water stays in each electrolysis chamber, A positive batch cleaning operation is performed by energizing the electrodes in each electrolytic chamber. When the positive batch cleaning operation elapses for a predetermined time, each electrolytically generated water generated in each electrolysis chamber is discharged, and the positive batch cleaning operation ends. The electrolyzed water generating apparatus waits until the electrolysis generating operation is started by the consumer.

  In the cleaning operation of this embodiment, in the region where the hardness of the raw water is less than 150 ppm, the reverse polarity batch type cleaning operation is pattern A (twice cleaning operation), and the positive polarity batch type cleaning operation is pattern A (one time). In the region where the hardness of the raw water is 150 ppm or more, the reverse polarity batch cleaning operation is set to pattern B (5 cleaning operations), and the positive polarity batch cleaning operation is set to pattern B (2 times). Thereby, the batch type washing | cleaning driving | operation corresponding to the area where the hardness of raw | natural water differs can be performed.

  In this embodiment, a means for converting the hardness of the raw water from the electrolytic current value of the raw water is adopted. The measured electrolysis current value of the raw water is converted into electrical conductivity using the graph shown in FIG. 9 (a), and the converted electrical conductivity is further converted into a graph shown in FIG. 9 (b). Converted into hardness. Based on the converted hardness, the amount of scale generated in the electrolysis chamber is estimated, and the number of batch cleaning operations with a reverse polarity and the number of positive batch cleaning operations are set.

  In this embodiment, when the raw water has a hardness of less than 150 ppm, the reverse polarity batch cleaning operation is set to 2 times, and the positive polarity batch cleaning operation is set to 1 time. When the raw water has a hardness of 150 ppm or more, The reverse polarity batch cleaning operation is set to 5 times, and the positive polarity batch cleaning operation is set to 2 times. The graph of FIG. 9C shows the consumption of the electrode when the raw water is less than 150 ppm in hardness and the batch cleaning operation is performed three times, and when the raw water is the hardness of 150 ppm and more and the batch cleaning operation is performed seven times ( Min), drainage (L), and power consumption (Wh).

  In the batch type cleaning operation of this embodiment, if the current value exceeding the specified electrolytic current value exceeds a certain time during the batch type cleaning operation, one batch type cleaning is completed at that point. As a result, the cleaning operation is stopped, and the state in which the electrolytically generated water is retained in each electrolytic chamber is maintained until the set batch type cleaning operation time.

  In batch-type cleaning operation, if the electrolysis current value rises too much during batch-type cleaning, the electrolyzed water and electrolyzed water in the electrolysis chamber will be in a heated state, and resin parts such as spacers that make up the electrolytic cell May be deformed to cause a decrease in function, water leakage from the electrolytic cell, and a decrease in the lifetime of the electrolytic cell. In this embodiment, this problem is addressed.

  The electrolyzed water generating apparatus that is the object of the cleaning operation of this embodiment employs an assembly 10A of electrode plate units 10 shown in FIG. 6, and a plurality of pairs of electrolysis formed by a plurality of pairs of electrode plates 10d and 10e. A room is provided. The electrolyzed water generating apparatus includes a total of five electrode plates 10d and 10e. However, when a voltage is simultaneously applied to the five electrode plates 10d and 10e at the start of electrolysis operation, an excessive inrush current is generated in the electrolysis chamber. There is a fear.

  In the present embodiment, in order to cope with such a problem, means for increasing the number of energized electrodes in a stepwise manner is employed when the electrolysis operation is started. FIG. 8 shows the current generated in the electrolytic chamber when a 12 V DC voltage is applied to the electrode plate in a state where electrolyzed water having a salt concentration of 0.2 wt% is supplied to the electrolytic chamber at a flow rate of 700 mL / sec. An experiment to measure the behavior was attempted.

  Experiment 1 measures the behavior of the current generated in the electrolytic chamber when voltage is simultaneously applied to the five electrode plates 10e1, 10d1, 10e2, 10d2, and 10e3. In Experiment 1, the inrush current is 27A. I'm getting results.

  Experiment 2 measures the behavior of the current generated in the electrolytic chamber when voltage is first applied to the four electrode plates 10e1, 10d1, 10d2, and 10e3, and then voltage is applied to one electrode plate 10e2. In Experiment 2, an experimental result with an inrush current of 20 A was obtained.

  In Experiment 3, voltage is first applied to the four electrode plates 10e1, 10d1, 10d2, and 10e3, then voltage is applied to one electrode plate 10e2 and voltage application to the two electrode plates 10d2 and 10e3 is interrupted. Then, the behavior of the current generated in the electrolytic chamber when a voltage is applied to the two electrode plates 10d2 and 10e3 is measured. In Experiment 3, an experimental result with an inrush current of 18A was obtained.

  In the electrolyzed water generating apparatus, assuming that there is much use in the daytime and almost no use at midnight, one day (24 hours) is a time zone for performing the electrolysis generation operation and a time for performing the cleaning operation. It is divided into bands and managed by a 24-hour timer that can measure 24 hours. However, when the accumulated time of the electrolysis generation operation in the time zone for performing the electrolysis generation operation reaches a certain time, it is necessary to perform the cleaning operation on the assumption that the scale generated in the electrolysis chamber has reached the limit. . It is a nuisance for consumers to suddenly enter a batch-type cleaning operation during a time period during which an electrolytic generation operation is performed. In this embodiment, this problem is addressed.

  In this embodiment, the batch cleaning operation timing is controlled by a 30-minute timer that measures 30 minutes and a 60-minute timer that measures 60 minutes. The type cleaning operation is performed at a time set in the time zone of the cleaning operation (for example, 12:00 at midnight).

  In this embodiment, the 30-minute timer measures the accumulated time required for the electrolysis operation in the time zone in which the electrolysis generation operation is performed, and when the accumulated time reaches the set time (30 minutes), the cleaning operation time zone It functions to issue a command to perform a cleaning operation at. In addition, the integration time for the scale generated in the electrolysis chamber to reach the limit is set to 60 minutes, and the 60 minute timer measures the integration time required for the electrolysis operation in the time zone for performing the electrolysis generation operation. When the time reaches 60 minutes, the subsequent electrolytic generation operation is stopped, and a command to perform a batch cleaning operation is performed.

  In this case, the cleaning lamp attached to the operation panel A1 is turned on when the integration time of the 60-minute timer reaches 50 minutes. Thereby, the consumer can recognize that the cleaning operation is near by visually confirming the lighting of the cleaning lamp. In this case, the consumer can perform the batch-type cleaning operation manually under arbitrary judgment. In the electrolyzed water generating apparatus, batch cleaning operation is automatically performed when the lighting time of the cleaning lamp reaches a set time. Thereby, the trouble which a consumer gives can be reduced. The consumer can wait for the time when the batch-type cleaning operation ends to start the electrolysis generation operation of the electrolyzed water generation apparatus.

  For the 24-hour timer employed in this embodiment, the time measured by the 24-hour timer is displayed on the operation panel A1, and the time displayed by the 24-hour timer is the current time. If the time is different from the time, the time of the 24-hour timer can be corrected to the current time.

  In the electrolyzed water generator, the salt water supply pump E is used to prepare the electrolyzed water, and the number of strokes (salt water supply stroke) of the salt water supply pump E (for example, in the range of 30 to 60 times / minute). By controlling the above, dilute salt water (electrolyzed water) having a predetermined concentration is obtained. For this reason, in the said electrolyzed water production | generation apparatus, when it continues for a fixed time in the state which the salt water supply stroke frequency increased extremely, the means to stop an electrolysis operation | movement can be taken. In this embodiment, it is estimated that the scale has adhered and accumulated in the electrolytic chamber from the number of times of the salt water supply stroke, and the batch type cleaning operation is controlled.

  In this embodiment, the control device stores the number of strokes of the salt water supply stroke at the start of the initial operation, and when the number of strokes reaches 2.1 times the number of initial strokes, the salt water immediately after continuing further When it is determined that cutting occurs, a cleaning warning is displayed and / or the cleaning operation is stopped.

  In this embodiment, the control device determines that scale deposition has occurred in the electrolytic cell at the point in time when the batch cleaning operation has continued for 1 hour, and then displays a cleaning warning and then continues. Then, the batch cleaning operation is performed, and the batch cleaning operation is stopped when the number of strokes reaches three times the number of initial strokes.

  By taking such scale adhesion determination, it is possible to improve the life of the electrodes and the diaphragm that constitute the electrolysis chamber, and it is possible to shorten the time required for removal (cleaning) of the scale that adheres and accumulates. . In addition, it is not necessary to open the electrolytic cell D in order to check the scale that has adhered and deposited, and the time for confirming the scale can be shortened. It is possible to shorten the electrolytic operation time of the generator.

  In the electrolysis operation of the electrolyzed water generator, when performing reverse electrolysis operation in which the polarity of the electrode is reversed, in order to reverse the polarity of the electrode, a large load is applied to the electrode, and when the load is repeatedly applied, Life is shortened early. Therefore, also in the electrolytic operation method of the present invention, it is required to reduce the polarity reversal (polarity switching) of the electrodes as much as possible. In addition, in the batch cleaning operation, the generated electrolyzed water does not continuously flow into the outflow pipe and the like, and therefore, the scale that adheres and accumulates in the outflow pipe or the like cannot be easily removed. There is a fear, and it is necessary to increase the number of reverse-polarity batch cleaning operations and positive-polarity batch cleaning operations. The present embodiment addresses such problems.

  In the present embodiment, the reverse polarity flowing water type cleaning operation is performed prior to the reverse polarity batch type cleaning operation employed in the present invention. If reverse-polar water-flow cleaning operation is performed prior to reverse-polar batch cleaning operation, a large amount of scale that adheres to and accumulates in the electrolysis chamber, outflow pipe, etc. before performing reverse-polar batch cleaning operation Thus, the load on the subsequent reverse polarity batch cleaning operation and the positive polarity batch cleaning operation can be reduced. This can reduce the number of reverse-polarity batch cleaning operations and positive-polarity batch cleaning operations, reduce the number of electrode polarity changes, and improve the electrode life. it can.

  In the electrolyzed water generating device, when the electrolysis operation stop button is pressed, the control device stops applying the voltage to the electrodes, stops driving the salt water supply pump, delays several seconds, and turns on the water supply valve. Closed control is performed. Thereby, while the closing of the water supply valve is delayed, the electrolyzed water in the electrolysis chamber is expelled by the supplied raw water, thereby preventing the electrolytic cell from being damaged due to the electrolyzed water. The stop timing of the control is shown in FIG.

  In the control for stopping the electrolysis operation of the electrolyzed water generation apparatus, raw water is retained in each electrolysis chamber of the electrolysis tank, and in this state, it waits until the next electrolysis operation is commanded. For this reason, when starting the next electrolysis operation, it takes time for the electrolyzed water to be supplied to each electrolysis chamber to fill the electrolysis chamber, and feedback control of the driving stroke (supply stroke) of the salt water supply pump is performed. It takes time and a considerable amount of time is required until normal electrolytic operation is started. This embodiment addresses such a problem.

  In this embodiment, in order to cope with such a problem, when the electrolysis operation stop button is pressed, the control device stops applying the voltage to the electrode, delays several seconds, and stops the driving of the salt water supply pump. The control to close the water supply valve is performed. The stop timing of the control is shown in FIG. According to the control, the electrolyzed water is supplied to each electrolysis chamber in a state where no voltage is applied to the electrodes, and the electrolyzed water is supplied to each electrolysis chamber by closing the water supply valve. It will stay. For this reason, in the next electrolysis operation, the feedback control of the driving stroke of the salt water supply pump is performed in a short time, and the time required until the normal electrolysis operation is started can be shortened.

  In the electrolyzed water generating apparatus of this type, conventionally, a large water softener having a large water softening function is installed outside the main body of the electrolyzed water generating apparatus in order to soften the raw water. For this reason, it is necessary to perform piping work to install a water system pipeline between the main body of the device and a separate water softener, the piping work is complicated, and a large installation space is required for installing a large water softener. I was trying.

Since the electrolyzed water generating apparatus is equipped with a batch-type washing operation, the load on the water softener can be greatly reduced, and depending on the capability of the batch-type washing operation, the use of the water softener can even be abolished. it can. In this embodiment, paying attention to the fact that the load of the water softener is greatly reduced, compared with the conventional water softener in the middle of the raw water supply pipe line part 34a of the raw water supply mechanism 30B constituting the electrolyzed water generating device. Thus, an extremely small small water softener 35e is interposed. In other words, a configuration in which the small water softener 35e is built in the apparatus main body C is adopted.
For this reason, when installing the electrolyzed water generating device, it is not necessary to secure an installation space for separately installing the water softener, and complicated piping work of the water system pipe line with the separately installed water softener is not required. .
