Description

  The present invention relates to an electrolyzed water generating apparatus capable of generating electrolyzed water by electrolyzing water, and more particularly to a control unit.

  Conventionally, as an electrolyzed water generating apparatus, after purifying raw water such as tap water in a septic tank, it is supplied to an electrolyte adding part and an electrolyte such as calcium salt is added, and further supplied to an electrolytic tank to be electrolyzed and acidified. Some discharge ion water or alkali ion water to the outside of the apparatus (for example, refer to Patent Document 1).

  In such an electrolyzed water generating apparatus that has been generally performed conventionally, there is a device that displays whether it is suitable water or unsuitable water with a lamp or the like, and the display starts water flow. In many cases, after a certain amount of water has passed through or after a certain period of time has passed, a judgment is made from inappropriate water to suitable water. In addition, as an electrode cleaning means, there is one that performs electrode cleaning by reversing the polarity of the electrolytic cell for a certain period of time after the electrolytic water has been stopped, and when water is passed again during electrode cleaning, In many cases, determination of suitable water from the unsuitable water becomes slower than usual.

However, when performing the above-mentioned control, when water is used after being stopped from the water flow state and then immediately re-watered, water remains in the main body, so the water is already in the appropriate water. Despite the change, there is a contradiction that the display remains unsuitable water. Further, when the electrode is cleaned every time the water is stopped, there is a problem that the water must be discarded until the water is changed from an inappropriate water to a suitable water.

  The present invention has been made in view of the above points, and an object of the present invention is to provide an electrolyzed water generating device that can change from unsuitable water to suitable water as soon as possible and improve usability. .

  In order to solve the above problems, an electrolyzed water generating apparatus according to the present invention causes electrolyzed water to flow by flowing water into an electrolyzer and electrolyzing water by applying a voltage between electrodes arranged in the electrolyzer. The electrode cleaning means for cleaning the electrode by reversing the polarity from the electrolysis in the water flow while gradually draining the water in the electrolytic cell at the time of water stop, and provided upstream of the electrolytic cell In an electrolyzed water generating apparatus having a control unit that determines whether the water is suitable or unsuitable based on information from the flow sensor, the electrolysis water generator is restarted during a period before the water drains from the electrolyzer. A control unit is provided that corrects the determination criterion according to the amount of water remaining in the electrolytic cell when water is passed. With such a configuration, the need for unnecessary waste water can be minimized and the usability can be improved.

  In addition, the control unit sets the determination criterion so that the total amount of the total flow rate flowing into the electrolyzed water generating device and the amount of water remaining in the electrolyzed water generating device according to the water stop time is a constant amount. It is preferable to correct. By setting it as such a structure, it can recognize as water suitable at the time of water flowing out from a spout regardless of a water stop time, and usability improves.

  Moreover, it is preferable to provide a switch for switching between a normal mode in which the electrode is cleaned by the electrode cleaning means when the water is stopped and a continuous mode in which the electrode is not cleaned. By adopting such a configuration, the electrode cleaning water is not mixed even if re-watering is performed, so that the necessity of discharging inappropriate water can be minimized.

  As described above, in the invention according to the first aspect of the present invention, when the water is re-passed during the period before the water is drained from the electrolytic cell, the determination criterion is determined according to the remaining water amount in the electrolytic cell.

  In addition, in the invention of claim 4, in addition to the invention of claim 1, the control unit is provided in the electrolyzed water generating device according to the total flow rate flowing into the electrolyzed water generating device and the water stop time. Since the judgment criteria are corrected so that the total amount with the remaining water amount becomes a constant amount, it can be recognized as suitable water when the water flows out from the spout regardless of the stoppage time, and the usability is improved. It will improve.

  Further, in the invention of claim 5, in addition to the invention of any one of claims 1 to 4, a normal mode in which the electrode is cleaned by the electrode cleaning means when the water stops, and a continuous mode in which the electrode is not cleaned By switching to the continuous mode with this switch, the electrode cleaning water will not be mixed even if re-watering is performed, and the need to discharge inappropriate water can be minimized. is there.

The flow sensor 60 is resistant to the spring force by a rotatable wing that is urged by a rotational force in the direction opposite to the water flow by a spring force and the flow pressure of the water that flows through the water supply channel 17. What is comprised by the angle sensor which measures the rotation angle at the time of being rotated can be used. A downstream side of the water supply channel 17 is branched into a water supply main channel 14 and a drain channel 10.

Further, the acidic water discharge pipe 72 is led out to the outside of the apparatus, and its tip is external It is open toward.

  Next, the structure of the display operation part 21 of the electrolyzed water generating apparatus 1 of this invention is demonstrated.

Further, a reset switch 47b for resetting the accumulated amount is provided adjacently.

  Next, the usage method of the electrolyzed water generating apparatus 1 of this invention is demonstrated.

  First, the operation in the case of performing electrolysis in the alkaline ionized water level 1 generation mode as the electrolysis mode will be described based on the piping system diagram of FIG. 1, the block diagram of FIG. 5, and the flowcharts of FIGS. . In addition, when electrolyzing in another electrolysis mode, it can consider similarly to the case where it carries out in the level 1 production | generation mode of alkaline ionized water. In FIG. 1, the flow of water is illustrated by solid arrows.

  First, the user selects a mode by pressing the level 1 switch 41a2 of the alkaline ionized water on the main display operation unit 21a on the upper surface of the apparatus. At this time, the display unit 40a2 lights up in conjunction. Similarly, when the other switch 41 is pressed to select another mode, the associated display unit 40 is lit.

  As described above, in the state where the switch 41 is pressed and the mode is selected, the water tap 7 is opened, and raw water such as tap water is supplied to the water supply port 2 of the electrolyzed water generating apparatus 1 through the water supply hose 8.

  At this time, the raw water sent to the water supply port 2 is sent from the inlet 18 to the water purification cartridge 4 through the intake channel 9, and residual chlorine, musty odor, trihalomethane, agricultural chemicals, etc. are removed by the purification agent 6 in the adsorption clarification tank 15. Is done. Subsequently, it is filtered by passing through the filtration membrane 5 of the filtration tank 16 to remove fine turbidity, bacteria, and the like. In this way, the raw water is filtered through the purified water cartridge 4 so that the raw water is purified to produce purified water.

  The generated purified water flows out from the outlet 19 to the water supply channel 17, but passes through the flow sensor 60 when flowing through the water supply channel 17.

  Based on the signal sent from the flow sensor 60, the control unit 49 applies a voltage between the anode 67 and the cathode 66 to determine whether to start electrolysis (see FIG. 5).

  The purified water flowing through the water supply channel 17 is supplied from the inlet 54 to the electrolyte adding unit 50 through the water supply main channel 14.

  The purified water supplied to the electrolyte addition unit 50 is provided with a dissolved electrolyte. The water provided with the electrolyte flows into the added water supply channel 11 from the upper outlet 93 through the main supply channel 13 and is supplied from the inlet 68 to the cathode chamber 65 and the anode chamber 64 of the electrolytic cell 62. . At this time, after water is supplied to the electrolyte adding portion 50 up to the position where the upper outlet 93 is formed, the water mainly flows out from the upper outlet 93, and stays in the electrolyte adding portion 50 to some extent, and the electrolyte. Water that has been sufficiently added flows out from the electrolyte addition unit 50.

  At this time, the purified water that has passed through the water purification cartridge 4 is supplied to the electrolytic cell 62 after passing through the electrolyte addition unit 50, and the electrolyte concentration in the water supplied to the electrolytic cell 62 is sufficiently ensured. Thus, electrolysis in the electrolytic cell 62 is efficiently performed.

  Then, alkaline ionized water is generated in the cathode chamber 65 and acidic ionized water is generated in the anode chamber 64 by electrolysis. Alkaline ion water generated in the cathode chamber 65 flows into the water discharge pipe 3 from the outlet 69 and is led out of the apparatus. On the other hand, the acidic ion water generated in the anode chamber 64 is discharged from the acidic water discharge pipe 72 through the discharge port 70 to the outside of the apparatus.

After the water flow is detected, the electrolytic cell 62 is filled with water until a predetermined time in the predetermined flow rate range in which electrolysis starts, that is, until a constant total flow rate (this is referred to as a first constant total flow rate) flows. Therefore, the control unit 49 does not perform electrolysis until the first constant total flow rate flows (see FIG. 7A). In the present embodiment, the first constant total flow rate is set to 150 cc (150 cm ³ ). During this time, the display unit 46 that displays “in production” is not discharged from the water discharge pipe 3 and before electrolysis is started, so it is determined that the water is not suitable. The light is turned off (see FIG. 5).

  This first constant total flow rate is corrected according to the amount of water remaining in the electrolyzed water generating apparatus 1 (including the electrolyzer 62 and each flow path) (see FIG. 9A). Conventionally, electrolysis was performed after a constant amount of water was passed regardless of whether the amount of remaining water was large or small. However, in the present invention, the amount of water flow (the first constant amount) By changing the total flow rate), electrolysis can be performed after passing the necessary and sufficient water. Therefore, the amount of waste water can be greatly reduced by the above correction. Specifically, when the time from the water stoppage to re-watering is short, the water in the electrolyzed water generating device 1 is not drained so much, so the first constant total flow rate correction amount (of FIG. 9A) As the amount of water remaining in the electrolyzed water generating device 1 decreases as time elapses from the water stoppage, the first constant total flow rate correction amount (of FIG. 9A) is increased. It is set in multiple stages according to the time from water stoppage to re-watering so as to reduce (corresponding to the correction value).

  As described above, the control unit 49 opens the water faucet 7 and reflows water, and the inside of the electrolyzed water generating device 1 according to the total flow rate of water newly flowing into the electrolyzed water generating device 1 and the water stop time. The set value is corrected so that the total amount with the remaining water amount (corresponding to the initial value in FIG. 9A) becomes a constant amount.

  In the present embodiment, as shown in the graph of FIG. 9, the time from water stoppage to re-watering is the time when the water remaining in the electrolyzed water generating apparatus 1 (excluding the water purification cartridge 4 and before) has almost disappeared. There are 6 levels including (50 seconds).

  As another example, a water amount sensor (not shown) for detecting the amount of water in the electrolyzer 62 may be provided in the electrolyzed water generating apparatus 1, and the actual remaining water amount may be detected by the water amount sensor.

When the first constant total flow rate flows, the electrolytic cell 62 is filled with water and can be electrolyzed, but a time difference occurs until the electrolyzed water reaches a predetermined pH. After the predetermined total flow rate, a suitable water state is not obtained until the second constant total flow rate further flows. In other words, this second constant total flow rate corresponds to the amount of water in the transition period until the desired electrolyzed water is obtained. Therefore, the display unit 46 that displays “generating” continues to be turned off. When the second constant total flow rate flows and the water is in a suitable state, the display unit 46 that displays “generating” is turned on (see FIG. 9B and FIG. 7A for the flowchart) The user can easily recognize that suitable water has been produced. In this embodiment, the second constant total flow rate is set to 150 cc (150 cm ³ ).

That is, whether or not the constant total flow rate has been reached from the detection of water flow is determined by the control unit 49 based on the flow rate detection signal from the flow rate sensor 60 and whether the water is suitable or not suitable for electrolysis. The display of the display unit 46 that displays “generating” is changed and notified (see FIG. 5). In the present embodiment, when a constant total flow rate of 300 cc (300 cm ³ ) at the maximum flows, a display section that displays “generating” is turned on.

  In the above operation, if the direction of the voltage applied in the electrolytic cell 62 is reversed, the cathode chamber 65 functions as an anode chamber to generate acidic ion water, and the anode chamber 64 serves as the cathode chamber. Alkaline ion water is generated by fulfilling the above function. At this time, acidic water flows into the water discharge pipe 3 from the outlet 69 and is led out of the electrolyzed water generator 1, and alkaline ionized water is discharged out of the electrolyzed water generator 1 from the acidic water discharge pipe 72 through the outlet 70. Is.

  Next, the operation when the supply of water into the electrolyzed water generator 1 is stopped will be described.

  When the water supply to the electrolyzed water generating device 1 is stopped by closing the water tap 7 by the user, the flow of water in the water supply flow path 17 is stopped, and the flow rate sensor 60 enters a water stop state. Therefore, the control unit 49 determines that the water is stopped. After the water has stopped, after the water in the water discharge pipe 3 has drained, air enters through the opening of the water discharge pipe 3, and the water remaining in the electrolytic cell 62 is caused to flow into the acidic water discharge pipe 72 or the bypass. It gradually escapes from the discharge pipe 75 via the flow path 120. In this example, when about 50 seconds elapse after the water stoppage, the water in the electrolyzed water generating apparatus 1 is almost lost (see FIG. 9A). At this time, if necessary, a reverse voltage is applied between the electrodes 66 and 67 to remove the scale on the surfaces of the electrodes 66 and 67, and then the voltage application between the electrodes 66 and 67 in the electrolytic cell 62 is stopped. Is done. Incidentally, in this embodiment, when the electrodes 66 and 67 are washed as described above after the water stoppage, it takes about 50 seconds until the water drains from the electrolytic cell 62 after the water stoppage (FIG. 9A). In this case, it is necessary to perform the above cleaning.

  Simultaneously with application of the reverse voltage, the display unit 40 is all turned off, and the electrode cleaning in-progress display unit 45 indicating that the electrode is being cleaned is turned on (see FIG. 5).

  Thereafter, drainage of the accumulated water remaining in the water flow path downstream from the water purification cartridge 4 in the apparatus, the electrolyte addition unit 50, and the electrolytic tank 62 is started by opening the drain valve 30. After the drainage is completed, the display unit 45 during electrode cleaning is turned off, and the display unit 40 (display unit 40a1 in the embodiment) is turned on.

In addition, when water flows into the electrolyzed water generating apparatus 1 again during the electrode cleaning and within a predetermined time after the electrode cleaning is completed, the display unit 46 that displays “generating” is separate from the first and second, Until the third constant total flow rate, the electrode cleaning water is mixed, so it is determined that the water is inappropriate and the light-off state is continued. At the same time, there is a danger of harming the body when drinking water in this state, so the warning sound generator 48 generates a warning sound to warn. In this embodiment, the third constant total flow rate is set to 500 cc (500 cm ³ ) after the flow rate sensor 60 detects water flow. As another example, the third constant total flow rate may be set after the first constant total flow rate flows (see FIG. 9B and FIG. 7A for the flowchart). Since the first constant total flow rate changes according to the time from the water stoppage to the re-watering, it is possible to shorten the period when the water is determined to be inappropriate.

  Further, if the electrode cleaning is performed every time water is stopped as described above, the life of the electrodes 66 and 67 can be extended, but the usability is deteriorated for the user. Therefore, when the water stops, the continuous mode selection switch 42b is displayed as a switch for switching between the normal mode in which the electrodes 66 and 67 are cleaned by the electrode cleaning means and the continuous mode in which the electrodes 66 and 67 are not cleaned. The main display operation unit 21a is provided with a display unit 42a for reducing the inappropriate discharge of water as much as possible to improve the usability. In this embodiment, the continuous mode is adopted, but the continuous mode is automatically canceled when the water stop time continues for a certain time or more, and the continuous mode is set only when necessary. When the continuous mode is unnecessary, electrode cleaning can be performed to maintain the lifetime of the electrodes 66 and 67. In this continuous mode, the same electrolysis mode as before the water stoppage is continued even when water is passed again after using the water in the predetermined electrolysis mode (see FIG. 6 for the flowchart, for example). ). Because of this, when using strong alkaline ionized water generation mode and acidic ionized water generation mode that were not suitable for drinking in the past, each time the water stopped, it automatically switched to a mode suitable for drinking. It is possible to use water and water repeatedly and to improve usability. That is, even if it is unsuitable for drinking, strong alkaline ionized water or acidic ionized water may be required for purposes other than drinking, but in conventional electrolyzed water generators, in order to obtain the above ionized water The selected electrolysis mode is automatically switched to the electrolysis mode to obtain ionized water suitable for drinking when water is passed again after stopping water to prevent accidental ingestion, and strong alkaline ionized water is required. It was inconvenient for the user who does it. However, in the electrolyzed water generating apparatus 1 according to the present invention, the electrolysis mode selected for obtaining strong alkaline ionized water or the like is not switched when re-watering after stopping water, and the electrolysis mode is re-performed. Since it is maintained after water, it is convenient for users who use the ionic water for purposes other than drinking.

  As an additional function of the continuous mode, the second constant total flow rate can be set shorter than the normal mode. This is because when the time from stop water to re-watering is short, the water in the electrolyzed water generating device 1 is not drained so much, and the electrolyzed water before the water stop remains, and therefore re-watered. This is because the time required to reach a predetermined pH is shortened. In the present embodiment, the second constant total flow rate is set to zero when the continuous mode is set. This further enhances usability.

  As another example, instead of the continuous mode, the electrode cleaning may be performed only when the water flow is stopped after a certain amount of time or the flow time of electrolysis has passed, and in this case, When the water flow is repeated, the electrode cleaning is performed once every plural times. Therefore, even if the continuous mode is not set, even if the water is passed again immediately after the water is stopped, it is possible to quickly generate suitable water.

  As another embodiment, when water is passed again after the continuous mode is released, the polarity is reversed during running in the stage before electrolysis is performed by applying a forward voltage between the electrodes 66 and 67. In addition, a water flow cleaning mode for cleaning the electrode may be provided (see FIG. 7B for a flowchart). In addition, when the continuous mode is canceled and water is passed again and the water is stopped again, the controller 49 may include a control unit 49 that increases the applied voltage for electrode cleaning from the normal level (see FIG. 8B for a flowchart). . In addition, when the continuous mode is canceled and water is passed again and the water is stopped again, the controller 49 may include a control unit 49 that extends the application time of electrode cleaning from the normal time (see FIG. 8A for a flowchart). . As a result, electrode cleaning that has been omitted in the continuous mode can be supplemented, and the life of the electrodes 66 and 67 can be extended.
