Registered Utility Model No. 2528154

  According to the ionic water generating apparatus of the background art, when the water is not used for a long time, water discharge at the initial stage of water flow is not used, and further, water in the apparatus is not always generated beyond an allowable amount. You can save water compared to the device that does. However, when the unused time exceeds the set value and when it does not exceed, in other words, it is only switched whether or not the accumulated water is drained depending on whether or not it is used for a predetermined time based on the passage of water. Then, it has the subject that it cannot prevent reliably containing the water containing the bacteria which proliferate with time passage. Further, from the viewpoint of water saving, there is a problem that sufficient water saving cannot be performed only by switching whether or not the accumulated water is drained depending on whether it is not used for a predetermined time or when it is used. Furthermore, the ionic water generator is capable of generating alkaline water even in a state of passing water, alkaline water generating mode for generating alkaline water, purified water mode for passing water without generating ionic water, and acidic water for generating acidic water. There are multiple modes such as generation mode, and it is necessary to drain water when changing the mode, but if this drainage amount is constant, it can be used not only that sufficient water saving can not be done. There is a problem that the time until the water is supplied always takes a predetermined time and cannot satisfy the user's request to use it quickly.

  The present invention has been made to solve the above-mentioned problems, and it is possible to appropriately drain water that is not preferable for the use of bacteria, etc., and to realize sufficient water saving and a reduction in transition time until it can be used. It aims at providing a simple water purification apparatus.

The ionic water generating device according to the present invention includes a flow rate sensor that measures a flow rate and outputs it as an electrical signal, a control circuit that calculates the flow rate based on the electrical signal output from the flow rate sensor, and a drainage channel discharge. An electromagnetic valve disposed near the outlet and controlled to be opened and closed by the control circuit, wherein the control circuit generates alkaline water during generation of acidic water in an acidic water generation mode for generating acidic water when migrating to alkaline water generation mode, in the case of at least one when migrating from the acidic water while generating the acid water generation mode to passing water water purification mode for water flow that does not generate ion water, from the flow sensor based on the signal, the third the discarded water through water perform the opening and closing of the solenoid valve in line Migihitsuji, acidic alkaline water during the production of the alkali water generation mode acidic water generating mode When shifting during generation, when shifting from alkaline water generation in alkaline water generation mode to passing water in purified water mode, when shifting from passing water in purified water mode to acidic water generation in acidic water generation mode, in at least one when migrating from passing water into alkaline water while generating the alkaline water generation mode, based on a signal from the flow sensor, the solenoid valve discarded water fourth through water in a row Migihitsuji It opens and closes the one in which the third through water control rather greater than the fourth through water. As described above, in the present invention, when shifting from the generation of acidic water in the acidic water generation mode for generating acidic water to the generation of alkaline water in the alkaline water generation mode for generating alkaline water, the generation of acidic water in the acidic water generation mode In at least one of the cases of shifting to the water flow of the purified water mode in which the ionic water is not generated from the water, the third water flow is discarded, and the acidic water is generated from the generation of the alkaline water in the alkaline water generation mode. When transitioning to generation mode acidic water generation, when shifting from alkaline water generation of alkaline water generation mode to passing water of purified water mode, shifting from passing water of purified water mode to acidic water generation of acidic water generation mode In the case of shifting to the alkaline water generation in the alkaline water generation mode from the water flow in the clean water mode, at least one of the cases where the fourth water flow is discarded Since the third water flow rate is larger than the fourth water flow rate, the acidic water is used for face washing, boiled noodles, tea astringents, etc., while the alkaline water is used for cooking / tea, cooking rice, starting drinking However, it is preferable to be ingested by humans because it is alkaline and acidic water must be avoided. In other words, water that is discharged from the electrolyzed water outlet in the alkaline water generation mode must be alkaline water. Since it is not preferable that a part of the water is acidic water, the amount of discarded water is slightly larger, whereas water is discharged from the electrolyzed water outlet in the generation state of the acidic water generation mode. The water must also be acidic water, but it is not necessary to make a sufficient amount of discarded water. Thereby shortening the waiting time until the possible use of user, it is possible to eliminate the waste of water.

  The panel 90 is disposed in the center of the front side of the ionic water generating apparatus. As shown in FIG. 3, the power button 90a, the ORP display button 90b, the water flow rate display button 90c, Alkaline water supply button 90d, first level alkaline water supply button 90e, second level alkaline water supply button 90f, third level alkaline water supply button 90g, purified water supply button 90h, acidic water supply button 90i, sanitary water ( Strong acidic water) supply button 90j, life setting up button 90k, life setting down button 90l and reset button 90m. It also has a 7-segment LED 91 that displays information such as pH (pH), ORP, and water flow rate. The power button 90a is a button for starting the present ion water generating device, and is an effective button in any state. Even if the power button 90a is pressed, if the process such as the drainage process is not completed, it is preferable that these processes are completed and the power is turned off. The ORP display button 90b is a button for causing the 7-segment LED 91 to display the current ORP of water. The water flow amount display button 90c is a button for causing the 7-segment LED 91 to display the current water flow amount. The strong alkaline water supply button 90d is a button for instructing the ion water generating device to generate strong alkaline water. Strong alkaline water, for example, has a pH (pH) of 10.5, and can be used for boiled foods, pickled vegetables, boiled vegetables, and the like. The first level alkaline water supply button 90e is a button for instructing the ion water generating apparatus to generate the first level alkaline water.

The purified water supply button 90h is a button for instructing that the water from the tap water is allowed to pass through the ionic water generating apparatus without generating ionic water. The acidic water supply button 90i is a button for instructing the ion water generating apparatus to generate acidic water. Acidic water has a pH (pH) of 5.5, for example, and can be used for face washing, boiled noodles, tea astringents, and the like. The sanitary water supply lamp 90j indicates that the present ion water generator is in the sanitary water generation mode. The sanitary water has a pH (pH) of 2.5, for example. The life setting up button 90k also has a different life depending on the type of the upper water purification cartridge 42. Therefore, this button is used to set the life of the upper water purification cartridge 42. This is performed once when a cartridge different from the one used up to now is set and used. The life setting lower button 90l is the same as the life setting upper button 90k, and is different only in that it is for the lower water purification cartridge 31. The reset button 90m resets the accumulated water flow amount that has been accumulated until now, and actually clears the accumulated water flow amount counter present in the control circuit 50. The reset button 90m is enabled by long-pressing for 2 seconds, and prevents the integrated water flow rate from being reset by being erroneously pressed. The reset button 90m is performed when the upper water purification cartridge 32 or the lower water purification cartridge 31 is replaced. The strong alkaline water supply button 90d, the first level alkaline water supply button 90e, the second level alkaline water supply button 90f, the third level alkaline water supply button 90g, the purified water supply button 90h, and the acidic water supply button 90i are: The currently active button is lit and visible to the user. In addition, a temperature increase lamp for notifying the user when a temperature increase in the electrolytic cell 10 occurs is also arranged on the operation panel. In addition, there are a cleaning lamp 90n and a rinsing lamp 90o, which will be described later.

  As already described with respect to each button, in this ion water generating apparatus, it is roughly divided into an alkaline water generating mode for supplying alkaline water, a purified water mode for supplying purified water, an acidic water generating mode for supplying acidic water, and sanitary water. There are four generation modes of the sanitary water generation mode for supplying water. The alkaline water generation mode includes a strong alkaline water generation mode, a first level alkaline water generation mode, a second level alkaline water generation mode, and a third level alkaline water generation mode in the order of strong alkalinity. In the alkaline water generation mode, the second electrode plate 12 and the third electrode plate 13 are used as cathode plates and the first electrode plate 11 is used as an anode plate under the control of the control circuit 50 with the electromagnetic valve 63 opened. To do. In the alkaline water generation mode of each level, the applied voltage is different, and the strong alkaline water generation mode, the first level alkaline water generation mode, the second level alkaline water generation mode, and the third level alkaline water generation mode are relative to each other in this order. High voltage is applied. In the water purification mode, no voltage is applied to any of the electrode plates 11, 12, 13 with the electromagnetic valve 63 closed, that is, no electrolysis is performed. Here, by closing the electromagnetic valve 63, useless water is not discharged from the discharge port 63. In the acidic water generation mode, the second electrode plate 12 and the third electrode plate 13 are used as an anode plate and the first electrode plate 11 is used as a cathode plate under the control of the control circuit 50, contrary to the alkaline water generation mode. To do.

  When the above generation mode is set to the generation state, there are other states in the ion water generator, and the power off state, the standby state, the drainage state, the discarded water state, the washing state, and the generation stop state are not turned on. There are a retry state and a rinse state. These states will be described below based on FIGS. 4 to 7 together with the transition to each state.

  A state where the power button 90a of the operation panel 90 is pressed from the power-off state to activate the ionic water generating device is a standby state. The standby state is a state where water is not being passed (except for water passing at a level that cannot be detected by the flow sensor), and the electromagnetic valve 63 is closed. Normally, the electromagnetic valve 63 needs to be opened in order to drain the ionic water having a polarity that is not used when the ionic water is generated. In the standby state where the ionic water is not generated, the electromagnetic valve 63 needs to be opened. Since it is not necessary to keep the valve 63 open, the valve 63 is closed. When the power is turned off from the standby state, the electromagnetic valve 63 is in a closed state, and water is not discharged from the discharge port 62 even in the power off state. In the standby state, when the water flow of a predetermined amount or more is not performed, the state moves to the drainage state in which the electromagnetic valve 63 is opened and the staying water is drained. This is because when water has accumulated in the addition cylinders 41 and 42, the electrolytic cell 10, the auxiliary electrolytic cell 20, and each water channel when the state has shifted from the other state to the standby state, as the time passes, This is to prevent bacteria and the like from growing. Therefore, the transition from the standby state to the drained state and the return to the standby state after a predetermined time has elapsed after completion of the drainage are performed every predetermined time, and the stagnant water that serves as a hotbed for growth of germs, bacteria, and the like is drained. The transition to the power-off state, standby state, and drainage state is the same regardless of the currently selected generation mode. Since the transition to the other state differs depending on the currently selected generation mode, each of the generation modes, that is, the alkaline water generation mode, the acidic water generation mode, the purified water mode, and the sanitary water generation mode will be described below in order.

  In the case where the alkaline water generation mode is selected, when water is passed from the standby state or the drainage state, the solenoid valve 63 is opened to shift to a discarded water state in which accumulated water is discarded for a predetermined amount or a predetermined time ( Hereinafter, refer to FIG. After the discarded water in the discarded water state is completed, the process proceeds to the generation state of the alkaline water generation mode described above. When an overcurrent or an undercurrent is generated in the electrolytic cell 10 during the alkaline water production mode, a transition is made to a retry state in which no ionic water is produced without applying a voltage to the electrode plates 11, 12, and 13. In the retry state, a voltage is not applied to the electrode plates 11, 12, 13 at all, but a voltage is applied to the electrode plates 11, 12, 13 at a predetermined interval, and no overcurrent or undercurrent is generated in the electrolytic cell 10. Try it. Then, when the trial is successful, it returns to the generation state again. Here, in the generated state, when there is an overcurrent or an undercurrent in the electrolytic cell, the state does not shift to the retry state, but shifts to the retry state only when a predetermined retry condition is satisfied. This is because, in the case of an abnormality that does not make sense even if retries are made, not only may there be a possibility that repairs cannot be made by retries, but it is not preferable from the viewpoint of safety. Therefore, when the retry condition is not satisfied, or when the predetermined time has elapsed since the transition to the generation state of the alkaline water generation mode, the generation stop that closes the solenoid valve 63 after the predetermined period has elapsed after the state transition Transition to the state. In the case of shifting to the generation stop state due to current abnormality or temperature rise, if the water stops, the state shifts to the drained state. In the case of shifting to the generation stop state due to the elapse of the predetermined time after shifting to the generation state of the alkaline water generation mode, if the water stops, the state is shifted to the cleaning state. Even if it is a case where water stops in a production | generation state, it transfers to a washing state. In this cleaning state, the electromagnetic valve 63 is closed, the voltage application is reversed, and the second electrode plate 12 and the third electrode plate 13 that have become cathode plates in the alkaline water generation mode generation state are used as anode plates. The first electrode plate 11 is also changed from an anode plate to a cathode plate, and a voltage is applied for a predetermined period. By doing so, scales and the like attached to the electrode plates 11, 12, and 13 can be removed, and the next generation of ionic water can be performed smoothly. Here, the check valve 63 applies water pressure when passing water, and does not flow water toward the discharge water channel 82, but in the stopped state where water pressure is not applied, it flows water toward the discharge water channel 82. Therefore, the electromagnetic valve 63 is closed, and thereby the inside of the electrolytic cell 10 can be cleaned in a state sufficiently filled with water. When the application of voltage for a predetermined time in the washing state is completed, if it is normal, the state shifts to a drained state, and if water is passed, it shifts to the discarded water state without shifting to the drained state. Here, in the cleaning state, so-called reverse electricity is used to remove scales and the like, and the stagnant water contains impurities. In order to surely drain the stagnant water containing such impurities, the drained state or It has shifted to a discarded water state.

  In the case where the water purification mode is selected, when water is passed from the standby state or the drainage state, the electromagnetic valve 63 is opened to shift to a discarded water state in which the accumulated water is discarded for a predetermined amount or a predetermined time (hereinafter, referred to as “water purification mode”). (See FIG. 5). In the above-described purified water mode, the water supplied from the water pipe 66 through various water channels is discharged from the electrolyzed water outlet 64 without applying a voltage in the electrolyzer 10 after the water is discarded in the discarded water state. Transition to the generation state. There is no state that shifts from the generated state of the water purification mode under a predetermined condition. When the water flow is stopped and the water is stopped, the state is shifted to the drained state. The reason that the electromagnetic valve 63 is closed in the generation state is that water is not discharged from the discharge port 62 in vain.

  In the case where the acidic water mode is selected, when water is passed from the standby state or the drainage state, the electromagnetic valve 63 is opened to shift to a discarded water state in which the accumulated water is discarded for a predetermined amount or for a predetermined time (hereinafter referred to as the water flow mode). FIG. 6). After the discarded water in the discarded water state is completed, the state shifts to the generation state of the acidic water generation mode. When an overcurrent or an undercurrent is generated in the electrolytic cell 10 during the generation state of the acidic water generation mode, a transition is made to a retry state in which no ion water is generated without applying a voltage to the electrode plates 11, 12, and 13. In the retry state, voltage is not applied to the electrode plates 11, 12, 13 at all, but a voltage is applied to the electrode plates at a predetermined interval to test whether an overcurrent or an undercurrent occurs in the electrolytic cell. Then, when the trial is successful, it returns to the generation state again. Here, in the generated state, when there is an overcurrent or an undercurrent in the electrolytic cell 10, the state does not shift to the retry state, but shifts to the retry state only when a predetermined retry condition is satisfied. When the retry condition is not satisfied, or when a predetermined time has elapsed since the transition to the generation state of the acidic water generation mode, the generation stop state in which the electromagnetic valve 63 is closed after the predetermined period has elapsed after the state transition. Migrate to In the case of shifting to the generation stop state due to current abnormality or temperature rise, if the water stops, the state shifts to the drained state. In the case of transition to the production stop state due to the passage of a predetermined time since the transition to the production state of the acidic water production mode, if the water is stopped, it is normal without the transition to the washing state. If the water is transferred to the drained state and water is passed, the water is transferred to the discarded water state without shifting to the drained state.

  In the case where the sanitary water mode is selected, when water is passed from the standby state or the drainage state, the solenoid valve 63 is opened to shift to a discarded water state in which the accumulated water is discarded for a predetermined amount or for a predetermined time (hereinafter referred to as the water supply mode). FIG. 7). After the waste water in the discarded water state is completed, the state shifts to the sanitized water generation mode. When an overcurrent or an undercurrent is generated in the electrolytic cell 10 during the sanitized water generation mode, a transition is made to a retry state in which ion water is not generated without applying a voltage to the electrode plate. In the retry state, a voltage is not applied to the electrode plates 11, 12, 13 at all, but a voltage is applied to the electrode plates 11, 12, 13 at a predetermined interval, and no overcurrent or undercurrent is generated in the electrolytic cell 10. Try it. Then, when the trial is successful, it returns to the generation state again. Here, in the generated state, when there is an overcurrent or an undercurrent in the electrolytic cell 10, the state does not shift to the retry state, but shifts to the retry state only when a predetermined retry condition is satisfied. When the retry condition is not satisfied, the state shifts to a generation stop state in which the electromagnetic valve 63 is closed after a lapse of a predetermined period after the state shift. In the production state of the sanitary water production mode, compared with the case where normal water is electrolyzed in the electrolytic cell 10, the current is high because salt is mixed in the water. However, when the salt in the salt-added cylinder is completely dissolved, the salt concentration gradually decreases, so the current value decreases. In order to obtain a desired amount of sanitary water, the user puts salt in the salt addition tube 41 as necessary to operate. Therefore, it is the place where this ion water production | generation apparatus is scheduled that the density | concentration of salt will become small. Therefore, this apparatus shifts to the generation state (no salt) while continuing the generation of sanitary water when the concentration of sodium chloride becomes a predetermined current value. Moreover, even if it is a case where the assumed electric current value is not obtained even if a predetermined voltage is applied to an electrode plate from the beginning in the production | generation state of sanitary water production | generation mode, it transfers to a production | generation state (no salt). The generated state (no salt) indicates that there is no salt in the salt addition tube 41, the water in the electrolytic cell 10 is not a salt solution having a predetermined concentration, and the electrolysis is not performed smoothly, and for a predetermined time. Transition to rinsing after elapse. Rinsing is a state in which water is passed without applying voltage to the electrode plates 11, 12, 13 and the auxiliary electrode plates 21, 22 with the electromagnetic valve 63 opened. After the transition to rinsing, if the water is stopped, the state transitions to the drained state, the water passage state is maintained without stopping the water, and the transition to the generation stop state is made after a predetermined period. Even when 5 minutes have passed, the state has been shifted to the rinse state. This is because it can be estimated that all the sanitized water has been generated if 5 minutes have passed. It is only an example, and it may be changed to another predetermined time, and a configuration in which this state transition path is deleted can be used.

  In each of the above modes, the lamp 90n is turned on in the drained state and the washing state, and the rinse lamp 90o is turned on in the rinse state to alert the user. In addition to the lighting of these lamps, when the user passes water during the cleaning state and the drainage state, a warning sound is sounded for a predetermined period and the cleaning lamp blinks.

  The waste water in the waste water state when each mode is selected is not uniformly performed for a predetermined amount of time. Hereinafter, waste water control, which is a feature of the present invention, will be described in detail. The control circuit 50 does not shift from the standby state or the drainage state to the generation state as it is, but shifts to the generation state through the discarded water state. This is to treat the stagnant water that is preferably discarded at a minimum. When the control circuit 50 passes water for the first time after turning on the power, or when a predetermined time has passed since the water stoppage (the predetermined time is, for example, 15 [minutes] to 60 [minutes]. , Preferably 45 [min]), the first drainage water is discharged, and the second drainage water is discharged when the predetermined time has passed since the water stoppage. At this time, the first water flow amount (for example, 800 [cc] to 1100 [cc], preferably 1000 [cc]) is the second water flow amount (for example, 400 [cc] to 700 [cc], preferably 600 [cc]. cc]). In this way, the amount of discarded water was changed before and after the lapse of a predetermined time, because the bacteria and bacteria that grow in the water grow at a stretch over time. This reduces the amount of water used, shortens the waiting time of the user by making the transition to the generation state within a certain period of time, and further reduces the amount of discarded water, which is also suitable for the purpose of saving water.

  The discarded water of the first water flow amount or the second water flow amount relates to the transition from the water stop state to the supply state, but from the supply state of the ionic water generation state of a certain mode to another mode. In the case of a transition from the ionic water generation state to the supply state, the control circuit 50 controls the waste water as follows. That is, when the control circuit 50 shifts from the generation state of the acidic water generation mode to the generation state of the alkaline water generation mode or the generation state of the water purification mode, the control circuit 50 performs the third water passing amount to discard the alkaline water generation mode. When shifting from the generation state to the generation state of the acidic water generation mode or the generation state of the purified water mode, or when shifting from the generation state of the purified water mode to the generation state of the acidic water generation mode or the generation state of alkali generation, Drain the water with a flow rate of 4. At this time, the third water flow amount (for example, 450 [cc] to 700 [cc], preferably 600 [cc]) is the fourth water flow amount (for example, 200 [cc] to 350 [cc], preferably 250 [cc]. cc]). Thus, when shifting from the production state of the acidic water production mode to the production state of the alkaline water production mode or the production state of the purified water mode, the production state of the acidic water production mode or the production of the purified water mode from the production state of the alkaline water production mode The amount of wasted water was changed in the face wash in the case of shifting to the state, or in the case of shifting from the generation state of the purified water mode to the generation state of the acidic water generation mode or the generation state of alkali generation. Boiled noodles, tea astringents, etc., alkaline water is used for cooking, tea, rice cooking, starting drinking, etc. It is preferable that humans ingest alkaline, and acid water must be avoided. Because it must. That is, the water discharged from the electrolyzed water discharge port 64 in the alkaline water generation mode must be alkaline water, and part of the water is not allowed to be acidic water. On the other hand, water discharged from the electrolyzed water outlet 64 in the acidic water generation mode must also be acidic water, but it is not necessary to have a sufficient amount of discarded water. The amount of water discarded was such that alkaline water was not discharged. In addition, by reducing the waste water as much as possible, the transition to the waste water state is accelerated, and at the same time water saving is realized.

  In addition, sanitary water rinsing for reducing the concentration of the catalyst mixed in the water to be treated in the electrolytic cell 10 in order to shift to another mode when the production is stopped from the sanitary water production mode. If the sanitary water rinse has been completed when the next mode is entered, the fifth water flow is discarded, and the sanitary water rinse is incomplete. Dispose of water. At this time, the sixth water flow amount (for example, at least 800 [cc] to 1100 [cc], preferably 1000 [cc]) is the fifth water flow amount (for example, 200 [cc] to 350 [cc], preferably 250 [Cc]). In this way, when the production is stopped from the sanitary water generation mode, the sanitary water rinse is completed when the sanitary water rinse is performed and then the next mode is shifted, and the sanitary water rinse is incomplete. However, sanitary water is not used for beverages, and in alkaline water and purified water that can be used for beverages, it must be avoided to mix sanitary water. In addition, it is not limited to alkaline water and purified water, and even if it is acidic water, it is not preferable to use salt-containing water even if it is acidic water. When the water has been stopped before the rinsing is completed, the rinsing is incomplete and the rinsing needs to be completed. Because it can not be rinsed To respond, we are doing such a rinsing compensation for unfinished discarded water state when a next water passage.

  The first water flow amount matches the internal capacity of the ionic water generating device, and accordingly, when water is passed for the first time after turning on the power, or when a predetermined time has passed since the water stoppage, Even if the internal volume of the waste water is discharged and the staying water is wiped out and bacteria and the like are growing, it can be reliably removed. The second water flow rate coincides with the internal capacity of the electrolytic cell 10, and thus impurities such as the scale of the electrolytic cell can be eliminated. The amount of the third water flow matches the internal capacity of the electrolytic cell 10, and in this way, when water is passed before a predetermined time has passed since the water stoppage, the generation of alkaline water from the generation of acid water in the acid water generation mode is performed. When shifting to the mode of alkaline water generation or water purification mode water passing, the internal volume of the electrolytic cell 10 is discarded, and the acidic water remaining as stagnant water is discharged as water used by the user. The generated water in the specified mode can be provided to the user. The fourth water flow amount is an amount less than the internal capacity of the electrolytic cell 10, and accordingly, during the generation of the alkaline water in the alkaline water generation mode to the generation of acidic water in the acidic water generation mode or in the water purification mode. In the case of shifting to water flow in the purified water mode, when shifting to the generation of acidic water in the acidic water generation mode or generation of alkaline water in the alkaline water generation mode, the amount of discarded water is smaller than the third flow rate. However, as already mentioned above, the amount of discarded water with a margin should be slightly greater when the third amount of discarded water is used than when the fourth amount of discarded water is used. Because.

  Further, when the mode is shifted from the mode other than the sanitary water generation mode to the sanitary water generation mode, the seventh water passing amount is discarded. It is assumed that the seventh water flow amount is approximately the same as the fourth water flow amount. As with acid water, sanitary water is not required to have a sufficient amount of discarded water.

  In addition, it is possible to alert the user that the user should not use the lamp and the warning sound in the discarded water state. A separate lamp may be provided, but the cleaning lamp 90n or the rinsing lamp 90o is turned on, “NO USE” is displayed with a 7-segment LED, a purified water supply button 90h, an acidic water supply button 90i, a sanitary water supply lamp It is also possible to arrange a color LED at 90j so that the generation state is green, the discarded water state is red, and the retry state is yellow. In particular, when a color LED is used, each state can be recognized universally by emitting light corresponding to the traffic light.

  The electromagnetic valve 63 is controlled by the control circuit 50 and can be opened and closed. However, the check valve 65 is not controlled by the control circuit 50 and is always directed from the discharge water channel 82 toward the electrolytic cell water channel 83. When there is a water pressure at the time of water flow, not only the flow of water in the direction of the electrolyzer water channel 83 but also the flow of water from the electrolyzer water channel 83 toward the discharge water channel 82 is stopped. According to the above-mentioned background art, there are those having only a solenoid valve and those having only a check valve. In these, water discharge during reverse electrolysis is stopped, and water is discharged when water flows. It cannot be achieved that it does not pass in the direction of 82 and does not drain water during water purification. In other words, the electromagnetic valve 63 has a role of retaining the stagnant water that is likely to be discharged during reverse electrolysis and does not discharge water during water purification, and the check valve 65 supplies water from the direction of the discharge water channel 82 to the electrolytic cell water channel. The flow of water from the electrolytic cell water channel 83 in the direction of the discharge water channel 82 is prevented at the time of water flow. Next, the operation of using the ionic water generating apparatus according to this embodiment will be described. Here, the user uses the operation panel 90 to sequentially use the alkaline water generation mode, the water purification mode, the acidic water generation mode, and the sanitary water generation mode.

  First, the user inserts the power cord plug of the ion water generator into an outlet so that the power can be turned on. This state is a power-off state for the ionic water generator. Next, the power button 90a of the operation panel 90 is pressed to shift to a standby state (at this time, it is assumed that the purified water supply button 90h is in a selected state and is lit by factory default). The user pressed the first level alkaline water supply button 90e as well as the power button 90a, and twisted the water tap 67 to pass water. When the alkaline water supply button 90e of the first level is pressed, the standby mode of the purified water mode is switched to the standby mode of the alkaline water generation mode, and the water is continuously passed. Move to water. Since the water is flowing, the check valve 65 does not flow water toward the discharge water channel 82. Here, since the water flow is the first time when the power is turned on, the first water flow amount is discarded under the control of the control circuit unit 50. When water is discarded, the electromagnetic valve 63 is opened and the 7-segment LED 91 flashes. When the waste water is finished, the first electrode plate 11 is used as the anode plate, the second electrode plate 12 and the third electrode plate 13 are used as the cathode while the electromagnetic valve 63 is kept open under the control of the control circuit 50. A voltage is applied to the electrode plates 11, 12 and 13 from the power supply unit 61 so as to form a plate. Then, electrolysis of water occurs in the electrolytic cell 10, and magnesium ions, sodium ions, potassium ions, calcium ions, etc. are drawn to the cathode plate, and hydroxide ions, sulfate ions, nitrate ions, chlorine ions, etc. are drawn to the anode plate. Alkaline water is generated in the first electrolysis chamber 15 and the fourth electrolysis chamber 18, and acidic water is generated in the second electrolysis chamber 16 and the third electrolysis chamber 17. Then, alkaline water is discharged from the electrolytic water discharge port 64 through the auxiliary electrolytic cell 20 and the like. The user intends to use the discharged alkaline water for cooking, etc., obtains the alkaline water in the amount desired by the user, and closes the water tap 67 to stop the water flow. Since the water is stopped, the check valve 65 allows water to flow in the direction of the discharge water channel 82. Further, the state shifts from the generation state to the cleaning state, the electromagnetic valve 63 is closed, and the first electrode plate 11 serves as a cathode plate, and the second electrode plate 12 and the third electrode plate 13 serve as an anode plate. , 12 and 13 are supplied with the power supply 61 and apply a voltage under the control of the controller 50. That is, the voltage is applied contrary to the case where alkaline water was generated earlier. Then, the scales and the like attached to the second electrode plate 12 and the third electrode plate 13 that acted as the cathode plate when the alkaline water was generated peeled off and floated in the water in the first electrolysis chamber 15 and the fourth electrolysis chamber 18. It becomes a state. After applying a voltage for a predetermined time in the cleaning state, the state shifts to a draining state, the closed electromagnetic valve 63 is opened, and water mixed with impurities such as scale is drained from the discharge port 62. After a predetermined time has elapsed since the transition to the drained state, the standby state is shifted to a state where all the accumulated water has been drained.

  Next, the user presses the purified water supply button 90h of the operation panel 90. As a result, the first level alkaline water supply button 90e is turned on and the purified water supply button 90h is turned on, and the standby state of the alkaline water generation mode is shifted to the standby state of the purified water mode. Subsequently, the user passed the water tap 67 by twisting it. Since the water is flowing, the check valve 65 does not flow water toward the discharge water channel 82. Since the water was passed immediately from the standby state, the state shifted to the discarded water state without passing through the drained state. Here, since the previous generation of alkaline water, that is, before a predetermined time has elapsed since the water stoppage, the electromagnetic valve 63 is opened by the control of the control circuit unit 50, and the second water passing amount of the discarded water is discharged. Made. When water is discarded, the electromagnetic valve 63 is opened and the 7-segment LED 91 flashes. When the waste water is finished, the electromagnetic valve is closed, and a transition is made to a generation state where no voltage is applied to the electrode plates 11, 12, 13, 14. Then, purified water is discharged from the electrolyzed water discharge port 64 through the auxiliary electrolytic cell 20 and the like. At this time, since the electromagnetic valve 63 is closed, water is not discharged from the discharge port 62. It leads to point water that does not drain water wastefully. This is different from the production state in the alkaline water production mode. The user wanted to take the medicine using the purified water discharged, got the amount of purified water desired by the user, closed the water tap 67 and stopped the water flow. Since the water is stopped, the check valve 65 allows water to flow in the direction of the discharge water channel 82. Further, the generation state is shifted to the drainage state, the closed electromagnetic valve 63 is opened, and the accumulated water is drained from the discharge port 62. After a predetermined time has elapsed since the transition to the drained state, the standby state is shifted to a state where all the accumulated water has been drained.

  Next, the user presses the acidic water supply button 90i on the operation panel 90. Thereby, it turns from lighting of the purified water supply button 90h to lighting of the acidic water supply button 90i, and shifts from the standby state of the purified water mode to the standby state of the acidic water generation mode. Subsequently, the user passed the water tap 67 by twisting it. Since the water is flowing, the check valve 65 does not flow water toward the discharge water channel 82. Since the water was passed immediately from the standby state, the state shifted to the discarded water state without passing through the drained state. Here, since the predetermined time has elapsed since the generation of the purified water, that is, since the water stoppage, the electromagnetic valve 63 is opened by the control of the control circuit unit 50, and the first water flow amount is discarded. When water is discarded, the electromagnetic valve 63 is opened and the 7-segment LED 91 flashes. When the discarded water is finished, the first electrode plate 11 is set as the cathode plate, the second electrode plate 12 and the third electrode plate 13 are set as the anode while the electromagnetic valve 63 is kept open under the control of the control circuit 50. A voltage is applied to the electrode plates 11, 12 and 13 from the power supply unit 61 so as to form a plate. Then, electrolysis of water occurs in the electrolytic cell 10, and magnesium ions, sodium ions, potassium ions, calcium ions, etc. are drawn to the cathode plate, and hydroxide ions, sulfate ions, nitrate ions, chlorine ions, etc. are drawn to the anode plate. Acid water is generated in the first electrolysis chamber 15 and the fourth electrolysis chamber 18, and alkaline water is generated in the second electrolysis chamber 16 and the third electrolysis chamber 17. Then, acidic water is discharged from the electrolytic water discharge port 64 through the auxiliary electrolytic tank 20 and the like. The user intends to use the acid water discharged to wash the face, etc., obtains the amount of acid water desired by the user, and closes the water tap 67 to stop water flow. Since the water is stopped, the check valve 65 allows water to flow in the direction of the discharge water channel 82. Further, the generation state is shifted to the drainage state, the closed electromagnetic valve 63 is opened, and the accumulated water is drained from the discharge port 62. After a predetermined time has elapsed since the transition to the drained state, the standby state is shifted to a state where all the accumulated water has been drained.

  Next, in order to obtain a predetermined amount of sanitary water, the user puts salt corresponding to the predetermined amount into the salt addition tube 41. Then, the water channel switching 52 is switched so that the inflow port and the outflow port in the direction of the salt addition tube 41 are in a state in which flow is possible. When the water channel switching 52 is performed, the strong acid detection switch 53 outputs that the water channel has been switched to supply sanitary water to the control circuit 50, and the control circuit 50 supplies sanitary water from the lighting of the acid water supply button 90i. The lamp 90j is turned on and the standby state of the acidic water generation mode is shifted to the standby state of the sanitary water generation mode. Subsequently, the user passed the water tap 67 by twisting it. Since the water is flowing, the check valve 65 does not flow water toward the discharge water channel 82. Since the water was passed immediately from the standby state, the state shifted to the discarded water state without passing through the drained state. Here, since the generation of the acid water, that is, the generation of sanitary water regardless of the lapse of a predetermined time since the water stoppage, the electromagnetic valve 63 is opened by the control of the control circuit unit 50, and the first Waste water with a water flow of 7 is made. When water is discarded, the electromagnetic valve 63 is opened and the 7-segment LED 91 flashes. When the discarded water is finished, the first electrode plate 11 is set as the cathode plate, the second electrode plate 12 and the third electrode plate 13 are set as the anode while the electromagnetic valve 63 is kept open under the control of the control circuit 50. A voltage is applied to the electrode plates 11, 12 and 13 from the power supply unit 61 so as to form a plate. Then, electrolysis of water occurs in the electrolytic cell 10, and magnesium ions, sodium ions, potassium ions, calcium ions, etc. are drawn to the cathode plate, and hydroxide ions, sulfate ions, nitrate ions, chlorine ions, etc. are drawn to the anode plate. Sanitary water is generated in the first electrolysis chamber 15 and the fourth electrolysis chamber 18, and alkaline water is generated in the second electrolysis chamber 16 and the third electrolysis chamber 17. And sanitary water is discharged from the electrolyzed water outlet 64 through the auxiliary electrolyzer 20 and the like. The user intends to use the sanitized water discharged to wash the face, etc., and obtains the sanitary water in the amount desired by the user and passes the water as it is without stopping. Then, the amount of salt in the salt addition cylinder 41 decreases, the concentration of salt gradually decreases, and the current value in the electrolytic cell 10 also decreases at the same time. If this current value becomes a predetermined value or less, the control circuit 50 Shifts to the production (no salt) state. After a while after shifting to the generated (no salt) state, the state shifts to the rinse state. When the water passage is washed away by the rinsing state and the user stops the water, the check valve 65 causes water to flow in the direction of the discharge water passage 82, shifts to the drainage state, and drains the accumulated water from the discharge port 62. After a predetermined time has elapsed since the transition to the drained state, the standby state is shifted to a state where all the accumulated water has been drained.

  As described above, according to the ionic water generating apparatus according to the present embodiment, when the water is passed for the first time after the power is turned on, or when the water is passed after a predetermined time has elapsed since the water stoppage, the first amount of discarded water is passed. When the water flow has not passed for a predetermined time since the water stoppage, the second water flow rate is discarded, and the first water flow rate is larger than the second water flow rate. In order to grow at a stretch over time, the bacteria and bacteria are removed after a predetermined time, and within a predetermined time, the amount of waste water is reduced and impurities such as the scale of the electrolytic cell 10 are eliminated. In addition, the transition to the production state within a certain time can be made quicker, and further, the purpose of saving water can be met by the fact that the amount of waste water is reduced. Moreover, according to the ionic water production | generation apparatus which concerns on this embodiment, when shifting to the alkaline water production | generation of the alkaline water production | generation mode which produces | generates alkaline water from the acidic water production | generation of the acidic water production | generation mode which produces | generates acidic water, acidic water In at least one of the cases of shifting to the purified water flow mode in which the ionic water is not generated from the acidic water generation in the generation mode, the third flow rate is discarded, and the alkaline water generation mode is set. When shifting from alkaline water generation to acidic water generation in the acidic water generation mode, when shifting from alkaline water generation in the alkaline water generation mode to running water in the purified water mode, from the running water in the purified water mode to the acidic water generation mode. In the case of shifting during the generation of acidic water, in the case of shifting to the generation of alkaline water in the alkaline water generation mode from passing water in the purified water mode, Since the third water flow is larger than the fourth water flow, the acidic water is used for face washing, boiled noodles, tea astringents, etc., while the alkaline water is used for cooking / tea, For cooking rice, starting drinking, etc., it is preferable that humans ingest it directly because it is alkaline, and it must be avoided that it is acidic water, that is, water is discharged from the electrolyzed water outlet in the alkaline water generation mode. It must be alkaline water, and it is not desirable that some of the water is acidic. The water discharged from the water spout 64 must be acidic water, but it is not necessary to make a sufficient amount of discarded water. Therefore, the amount of discarded water should be set so that alkaline water is not discharged. And with discarded water and to shorten the waiting time until the available user by, it can be eliminated waste water. In addition, according to the ionic water generating apparatus according to the present embodiment, the production has been stopped from the sanitary water generating mode for generating strongly acidic sanitary water having higher acidity than the acidic water using NaCl or the like for promoting electrolysis. In this case, sanitary water rinsing is performed when a transition is made to the next mode after performing a sanitary water rinse that reduces the concentration of the catalyst mixed in the water to be treated in the electrolytic cell in order to shift to another mode. When the water flow is completed, the fifth water flow is discarded. When the sanitary water rinse is not completed, the sixth water flow is discarded, and the sixth water flow is the fifth flow. When the production is stopped from the sanitary water generation mode, the sanitary water rinse has been completed and the sanitary water rinse has been completed. The reason for changing the amount of discarded water when it was not completed was In the case of alkaline water and purified water that can be used for drinking, not for drinking, it must be avoided that sanitized water is mixed in, and not only alkaline water and purified water but also acidic water. It is not desirable to use salt-containing water even if it is acidic water, so it is desirable that the rinsing is completed. In the case of transition to the state, etc., the rinse is in an incomplete state, and it is necessary to complete the rinse, but if the water is stopped, the rinse cannot be performed. Such incomplete rinsing can be performed in the discarded water state when water has passed.

  In the ionic water generating apparatus according to the present embodiment, the water channel switch 52 is manually operated. However, the water channel switch 52 can be automatically operated by the control of the control circuit 50 by the operation panel operation 90, for example, By providing a sanitary water supply button and pressing the button, it is possible to make a configuration for shifting to the sanitary water supply mode as long as the salt is added to the salt addition tube 41 in advance.

  Moreover, in the ionic water production | generation apparatus which concerns on this embodiment, although the 4th water flow amount is also a fixed amount, the water flow (for example, 2 [second] thru | or 8 [second], Preferably 5 [ Seconds]) may be used as waste water, and if there is 5 seconds, sufficient water can be discarded if there are 5 seconds. However, as a user waiting for a usable state, the instability cannot be wiped off. It is a highly convenient configuration. In particular, as described above, water discharged from the electrolyzed water discharge port 64 in the acidic water generation mode must also be acidic water, but it is not necessary to make a sufficient amount of discarded water. It is sufficient to drain the fourth water flow amount, which is the amount of discarded water to the extent that alkaline water is discharged. Furthermore, if the fourth water flow amount can pass water for a predetermined time in this way, similarly, when the state is shifted from the generation state of the mode other than the sanitary water generation mode to the sanitary water generation state of the sanitary water generation mode. Even in this case, the water flow for a predetermined time (for example, 5 [seconds]) may be used as the discarded water without determining the water flow amount as the predetermined amount, and the same effect is produced. The reason is that sanitary water is not directly taken from the mouth more than acid water, and it is not necessary to provide a margin for the discarded water.

  In the ionic water generating apparatus according to the present embodiment, the default state of the electromagnetic valve 63 is closed, and the electromagnetic valve 63 is opened even when the power is turned off or the power plug is removed from the outlet. Even if it is, it can also be configured to close after a while, for example, a configuration in which it is biased by a spring or the like to the default state, so that the electromagnetic valve is maintained in an open state when power is not supplied from the power supply unit 61. In this configuration, the solenoid valve can always be closed in the power-off state, and even when the user passes water in the power-off state. It can be used without wasteful water from the outlet.

  In addition, when adding a description to the present embodiment, when discarding water, there are a case of discarding water depending on the amount of discarded water and a case of discarding water depending on a predetermined time. Can be disposed of properly, that is, when discarding water for a predetermined time, if the flow rate is small, the amount of water is small, and conversely, if the flow rate is large, the amount of water is large and the difference is large and stable. On the other hand, from the user's point of view, water can always be used for a certain start-up time. Therefore, these are appropriately used in the ionic water generator in the present embodiment. In addition, when the water amount sensor which can detect how much waste water has flowed in the vicinity of the discharge port 62 and the discharge port is provided, a certain amount of water can be discharged.

  Further, in addition to the description of the present embodiment, if the ionic water generator as shown in FIG. 1 is used, water in the electrolyzer 10, the salt-added tube 41, the calcium-added tube 42, etc. is lost by draining. It will be drained. However, which part of water is lost due to drainage depends on the arrangement of each component.

(Other embodiments)
In the ionic water generating apparatus according to the embodiment, when the power is turned off in the cleaning state, the last used drinking water mode (for example, third level alkaline water) is set when the power is turned on next time. This can prevent accidental drinking of acidic water.

  In the ionic water generating apparatus according to the embodiment, when the strong alkaline water, acidic water, sanitary water is generated, when water that is not suitable for drinking such as a washing state is generated or discharged, A buzzer can be sounded to alert the user.

  Moreover, in the ionic water production | generation apparatus which concerns on the said embodiment, the control circuit 50 can integrate | accumulate by the output of the flow sensor 51, and can count an integrated water flow amount. Especially in the ionic water production | generation apparatus which concerns on the said embodiment. There are a lower water purification cartridge 31 and an upper water purification cartridge 32, and the two cartridges can be added separately, and the user can be notified of the replacement time of the cartridge appropriately. That is, the lower water purification cartridge 31 is provided with an integrated water flow counter for the lower water purification cartridge 31 and a life water flow value that stores the life of the currently set cartridge. Then, the control circuit 50 adds the water flow rate based on the output of the flow sensor 51, and the control circuit 50 compares the life flow rate value at an arbitrary timing. It is preferable to notify the replacement with a slightly smaller value), and the lower water purification cartridge replacement timing lamp 90q is lit to notify the user that it is time to replace the lower cartridge. Similar to the lower water purification cartridge 31, the upper water purification cartridge 32 also has an integrated water flow counter, a life water flow value, and an upper water cartridge replacement timing lamp 90p, which operate in the same manner. In addition, there are a plurality of types of cartridges and the life may be different, but this can be changed by operating the life setting up button 90k (or the life setting down button 90l). When the water purification cartridge is replaced, the reset button resets the value counted by the integrated water flow counter as the integrated water flow amount of the water purification cartridge before replacement.

  Moreover, in the ionic water production | generation apparatus which concerns on the said embodiment, although it was the structure which always closed the electromagnetic valve 63 in the washing | cleaning state, it can also be set as the structure which opens the electromagnetic valve 63 in the final stage of a washing | cleaning state, and a waste_water | drain state It is possible to complete the drainage more quickly than when the solenoid valve 63 is opened after the transition to the waste water state or the transition to the waste water state, the state transition is performed quickly, and the waiting time of the user is shortened as a result. be able to.

  In the standby state, the electromagnetic valve 63 is closed. In order to prevent water overflow in this state, the flow rate sensor detects a flow rate equivalent to 0.3 [L] or more, and then 0.3 [L ] If it becomes less than a considerable amount, it can be shifted to a drained state. Here, 0.3 [L] is merely an example.

  In addition, while the cleaning in the cleaning state is started, the in-cleaning lamp 90n is turned on, the electromagnetic valve 63 is opened from a predetermined time before the cleaning ends, the drainage is performed together with the cleaning, and the drainage is continuously performed after the cleaning is completed. In the case of performing time, the in-cleaning lamp 90n can be turned on even when draining is continuously performed.

  In the ionic water generator according to the embodiment, the current value in the electrolytic cell is detected constantly or at predetermined intervals, and the current value in the electrolytic cell is still high when sanitary water soot is not completed. It is also possible to continue draining water, especially when shifting from sanitary water mode to alkaline mode, since it is water directly taken by the human body, it is necessary to provide enough water to be discarded. The effect of continuing to do is great.
