(First embodiment of the present invention)
Hereinafter, a water treatment apparatus according to a first embodiment of the present invention will be described with reference to FIGS. In the present embodiment, an example of an ion water conditioner that generates not only alkaline water and acidic water as the target water but also purified water that has been purified without electrolysis will be described.

  In each of the drawings, the water treatment apparatus 1 according to the present embodiment includes a water supply pipe 11 that introduces raw water, a water purification unit 20 that purifies the raw water, and a flow rate sensor 30 that measures the flow rate of water purified by the water purification unit 20. A salt addition cylinder 41 for adding salt to the purified water, a calcium addition cylinder 42 for adding calcium to the purified water, and a salt addition cylinder 41 and a calcium addition cylinder 42 for the water passed through the flow sensor 30. A flow path switching unit 51 for directing or switching, an electrolytic cell 60 having a plurality of electrode plates 61, 62, 63 and performing electrolysis of water that has passed through the salt-added tube 41 or the calcium-added tube 42; The discharge channel 16 for supplying the target water to be supplied, the discharge channel 18 for discharging the water not to be used, the control unit 70 for controlling each electrically connected unit, and the display for displaying various information such as the flow rate. Display image as a means A part 80, which is configured to include an operation unit 90 as an input means for accepting an operation input of the user.

  One end of the water supply pipe 11 is connected to the branch plug 13 provided in the water tap 12 and the other end is connected to the first water purification cartridge 21 of the water purification unit 20 in the apparatus housing 10. As the raw water supplied to the water treatment apparatus 1, tap water fed from the water pipe 14 through the water tap 12 is introduced into the apparatus.

  The said water purification part 20 is a structure provided with the 1st water purification cartridge 21 and the 2nd water purification cartridge 22, and is a mechanism which flows and purifies water in order of the 1st water purification cartridge 21 and the 2nd water purification cartridge 22. FIG. The first water purification cartridge 21 is mainly filled with activated carbon, and the second water purification cartridge 22 includes a relatively coarse filter such as a metal mesh, cloth material, filter paper, and other bacteria such as a hollow fiber membrane. It is provided with filtration means that can be removed up to.

  The flow rate sensor 30 is a known measuring device that measures the flow rate of water in the flow path between the second water purification cartridge 22 and the flow path switching unit 51, and detailed description thereof is omitted. The flow rate of water that has passed through the water purification unit 20 is grasped by the output of the flow sensor 30 being input to the control unit 70, and part of the water that passes through the water purification unit 20 is ion water or water purification as the target water. As a result, the control unit 70 can calculate the effective amount of water actually used for drinking and the like.

  The flow path switching unit 51 switches whether the water passed through the flow sensor 30 is directed to either the salt addition tube 41 or the calcium addition tube 42, and according to the type of ionic water selected by the user, Under the control of the control unit 70, the flow sensor 30 side flow path is switched to which of the salt addition cylinder 41 and the calcium addition cylinder 42 is connected. The flow path switching state in the flow path switching unit 51 is always grasped by the control unit 70. The switching in the flow path switching unit 51 may be performed by a direct manual operation by the user. In this case, the flow path switching state in the flow path switching unit 51 is integrated with the flow path switching unit 51. It is preferable to output an electrical signal to the control unit 70 with this detection switch.

  The said salt addition cylinder 41 is equipped with the salt (sodium chloride) as an electrolysis promoter used in order to make water strongly acidic in the electrolytic vessel 60 so that water can be added. A check valve 43 is provided on the outlet side of the salt addition tube 41 to prevent the backflow of water from the calcium addition tube 42 side to the salt addition tube 41 side. Moreover, the said calcium addition cylinder 42 equips water with the calcium agent as an adjuvant for supplementing electrolyte to water so that addition is possible. The flow path connected to the outlet side of the salt addition cylinder 41 via the check valve 43 and the flow path connected to the outlet side of the calcium addition cylinder 42 merge to form an electrolytic cell 60 as an electrolytic cell flow path 44. Connected to.

  The electrolytic cell 60 includes a first electrode plate 61 positioned in the center, two second electrode plates 62 and a third electrode plate 63 positioned so as to sandwich the first electrode plate 61, and each electrode plate. It is a structure provided with the partition 64 which is arrange | positioned and does not allow water to pass through while allowing ion to pass through. The electrolytic cell 60 is divided into four compartments of a first electrolysis chamber 65, a second electrolysis chamber 66, a third electrolysis chamber 67, and a fourth electrolysis chamber 68 by the electrode plates 61, 62, 63 and the partition walls 64. It is done.

  The electrolytic cell 60 communicates the inlet side with the electrolytic cell channel 44 and communicates the outlet side with the discharge channel 18 and the water discharge channel 16. Specifically, among the electrolysis chambers 65, 66, 67, 68 of the electrolysis tank 60, the outlet sides of the first electrolysis chamber 65 and the fourth electrolysis chamber 68 are connected to the water discharge channel 16, and the second electrolysis chamber 66. The outlet side of the third electrolysis chamber 67 is connected to the discharge flow path 18.

  The water discharge channel 16 is a tube through which ionic water or purified water used for use out of the water that has passed through the electrolytic bath 60 flows, and the tip of the water discharge channel 16 serves as a water discharge port 17. Further, the discharge flow path 18 is a tube through which ionic water, etc., that is not used among the water that has passed through the electrolytic cell 60 flows, and the end portion is a discharge port 19. In the discharge flow path 18, an electromagnetic valve 53 that controls the discharge of water is disposed in the vicinity of the discharge port 19, and an electrolytic cell flow path 44 is connected via the check valve 15.

  The electromagnetic valve 53 is opened and closed under the control of the control unit 70 to adjust the state of drainage from the discharge flow path 18. The electromagnetic valve 53 is opened to drain the unused ionic water that is generated at the same time as the ionic water to be used when the ionic water is being generated. The ionic water is not generated. In the standby state, there is no need to drain unused ionic water, so the closed state is set.

  The check valve 15 always stops the reverse flow of water from the discharge flow path 18 toward the electrolytic cell flow path 44, applies water pressure during water flow, and opens the electromagnetic valve 53 to open the discharge flow path 18. In a state where water is flowing, it is a mechanism for stopping the flow of water from the electrolytic cell channel 44 toward the discharge channel 18, and only from the electrolytic cell channel 44 toward the discharge channel 18 when water is not passed. It is to allow the flow of water into the water.

  The control unit 70 is electrically connected to the flow sensor 30, the flow path switching unit 51, the power supply unit 52, the electromagnetic valve 53, the display screen unit 80, and the operation unit 90, respectively, and information obtained from the flow sensor 30 and the like. Based on the operation input in the operation unit 90 of the user, the generation / supply of ionic water and purified water and other controls are executed.

  As a main control operation, the control unit 70 flows in accordance with the water generation mode selected based on the switch operation of the operation unit 90 by the user, taking into account the type of water to be generated and the immediately preceding situation. The switching of the path switching unit 51, the opening and closing of the electromagnetic valve 53, and the application of a predetermined voltage to each electrode plate 61, 62, 63 of the electrolytic cell 60 by the power source unit 52 are controlled, respectively, and the generation of the target water is performed with water flow It is a mechanism to make it happen.

  Among these, for the first electrode plate 61, the second electrode plate 62, and the third electrode plate 63 of the electrolytic cell 60, the power from the power supply unit 52 depends on the type of water to be generated and the situation such as cleaning. This is a mechanism for controlling the supply and applying a predetermined voltage to each of the electrode plates 61, 62, 63. Among these electrode plates, the second electrode plate 62 and the third electrode plate 63 have the same pole, but the first electrode plate 61 has a different pole from the second electrode plate 62 and the third electrode plate 63. The That is, when the second electrode plate 62 and the third electrode plate 63 are cathodes, the first electrode plate 61 is an anode, and conversely, when the second electrode plate 62 and the third electrode plate 63 are anodes, the first electrode plate 61 is an anode. The electrode plate 61 becomes a cathode.

  The generation mode of the water generated based on the control by the control unit 70 is roughly divided into an alkaline water generation mode for supplying alkaline water, a purified water mode for supplying purified water, an acidic water generation mode for supplying acidic water, There are four generation modes of sanitary water generation mode for supplying sanitized water. The alkaline water production mode includes a strong alkaline water production mode, a first alkaline water production mode, a second alkaline water production mode, and a third alkaline water production mode in descending order of the alkalinity of the produced water.

  Moreover, the control part 70 is calculating the flow volume of the water flowed based on the electrical signal output from the flow sensor 30, and also counts the integrated flow volume which integrated | accumulated this over the predetermined period, 1st water purification By integrating the cartridge 21 and the second water purification cartridge 22 independently and recording and holding the integrated value, it is possible to appropriately notify the user of the replacement time of the cartridge. That is, as an integrated flow rate counter for each water purification cartridge, the control unit 70 integrates the flow rate based on the output of the flow sensor 30 every time water passes through the cartridge by passing water, and the control unit 70 sets each cartridge at an arbitrary timing. Compared with the upper limit value of the flow rate stored as the lifetime of the cartridge, when the integrated flow rate is about to reach the upper limit value of the flow rate to be replaced, the user is notified that it is time to replace the cartridge. The upper limit value of the flow rate can be changed according to the type of cartridge, and when the water purification cartridge is replaced, the value counted in the integrated flow counter as the integrated flow rate for the water purification cartridge before replacement is automatically Or when the user operates the reset switch 90m at the time of replacement. The integrated flow rate may be displayed on the display screen unit 80 at all times or when the user operates the switch.

  Further, the control unit 70 uses known information such as the flow rate information output from the flow rate sensor 30 and the amount of water not used for the total amount of water flowing through the flow path with the flow rate sensor 30 immediately after the water purification unit 20. The calculation unit 71 as the calculation means for calculating the effective water amount that can be regarded as actually used for drinking or the like after exiting the spout 17 as the target water, and the obtained effective water amount as a total value or target water over a predetermined period A storage unit 72 that stores data for each type and the like, and a timer unit 73 that acquires and manages each time and elapsed time during a control operation including calculation start and stop in the calculation unit 71 are provided. It has a function of recording the amount of water used for drinking, etc., and displaying it on the display screen unit 80 as necessary.

  Specifically, the ionic water or purified water actually used as the target water that comes out of the spout 17 is used in the water that is not used, that is, in the electrolytic cell 60, from the amount of water in the flow path with the flow sensor 30. Excludes parts such as ionic water on the unused side, waste water that may be mixed with extraneous components immediately after passing water, and stagnant water that is discharged after remaining in the device for a specified time or longer. The flow rate sensor 30 cannot directly measure and acquire the amount of target water used. However, in the calculation unit 71, the flow rate obtained by the flow rate sensor 30, that is, immediately after flowing into the apparatus and passing through the water purification unit 20. , A value representing the total amount of water including both the target water and the portion not used, the set amount of waste water stored in advance in the storage unit 72 and the total amount of water discharged from the discharge port 19 Use percentage of quantity A mechanism for calculating estimated effective amount of water corresponding to the amount actually used drinking, etc. out of the spout 17 of the objective water.

  The calculation unit 71 is discharged from the set amount of waste water or the discharge port 19 with respect to the flow rate immediately after the water purification unit 20 obtained by the flow rate sensor 30 and the total amount of water in the flow channel with the flow rate sensor 30. By using a predetermined value such as the proportion of water that is occupied, the amount of waste water that cannot be directly measured and the amount of drainage discharged from the discharge port 19 through the discharge channel 18 are also calculated, similar to the effective amount of water. In addition, in the usage conditions such as the type of target water such as alkaline water and purified water and the interval of water flow, the set amount of discarded water, the presence or absence of water discharged from the discharge port 19 during water flow, and the ratio to the total amount are respectively For example, in the case of alkaline water, it is necessary to calculate in consideration of the flow rate ratio with the acidic water discharged from the discharge port 19, whereas in the case of purified water, ions that are not used because there is no electrolysis Although the calculation conditions are different, for example, the ratio of the effective water amount to the total amount of water increases compared to the case of alkaline water because water is not generated and there is no drainage from the discharge port 19, the calculation unit 71 switches the operation unit 90. In accordance with the selection of the water generation mode by the operation, such a known condition is read from the storage unit 72 to adjust the calculation method.

  And in the calculation part 71, after water flow start, the flow rate information output from the flow sensor 30, the set amount of the waste water read from the storage part 72, and the flow rate sensor 30 part flow path of the water discharged from the discharge port 19 Using the known information such as the ratio of the total amount of water flowing through the water, first calculate the amount of waste water that exits from the same outlet 17 as the target water, compare the amount of this waste water with the set amount, After the predetermined amount of time, when the set amount of discarded water is discharged, the discarded water state ends and the target water is generated. That is, the target water is not the water that may contain foreign components. The time point at which water having the same quality as the predetermined ionic water or purified water is discharged is determined, and the calculation of the effective water amount is started with this point as the target water supply start point. The obtained value of the effective water amount is output to the display screen unit 80, and the measurement display of the effective water amount is started almost simultaneously with the calculation on the display screen unit 80. However, in this embodiment, the effective water amount is displayed on the display screen unit 80 in the name of “used amount” to facilitate the understanding of the user, and the calculation unit 71 calculates the effective water amount and displays the display screen unit 80. The effective amount of water is displayed only for alkaline water (excluding strong alkaline water) and purified water for drinking.

  In the calculation unit 71, the effective water amount is calculated and displayed on the display screen unit 80 at each use opportunity until the target water is discharged and stopped. By storing in the storage unit 72 at the end of the calculation, the total value of each effective water amount at a plurality of usage opportunities from a predetermined time is also calculated. For example, the effective water amount from the beginning of a certain day is totaled. It is a mechanism that can finally obtain a total value corresponding to the amount of use. In this case, the potable water for which the effective water amount is calculated and displayed, that is, the total effective water amount is totaled by combining the effective water amounts of alkaline water excluding strong alkaline water and purified water that does not undergo electrolysis. I handle it. The display screen 80 displays the effective water amount at that time in the target water generation state and also displays the total effective water amount totaled from a certain time. The display of the total effective water amount is displayed in the name of “total use amount” as in the case of the effective water amount.

  The total effective water amount from a certain point in time in the calculation unit 71 and the display on the display screen unit 80 can be reset from any point in time by resetting the summation and storage in the storage unit 72 by the user's operation of the reset switch 90m. You can start anew.

  The display screen unit 80 is disposed on the front surface of the apparatus housing 10 and displays information such as the pH value, ORP (oxidation-reduction potential) value of discharged water, effective water amount, and total effective water amount as the display means. Is. In addition to this, the display screen unit 80 also displays a temperature increase display to notify the user when the temperature in the electrolytic cell 60 rises, and a drain / washing display that lights to notify the user when the temperature is in the drained or washed state. The display function includes a rinsing display that lights up in a rinse state to alert the user, a first water purification cartridge replacement time display for notifying the replacement time of each water purification cartridge, and a second water purification cartridge replacement time display. The display screen unit 80 may be configured as an operation input unit as a so-called touch panel. Further, in addition to the display function of the display screen unit 80, a notification unit that sounds a warning sound for a predetermined period when the user passes water in the cleaning state and the drainage state may be provided in accordance with the apparatus housing.

  The operation unit 90 is arranged in the center of the front surface of the apparatus housing 10 and includes various switches that can be operated by the user. The switches include a power switch 90a for switching the start / stop of the apparatus, an ORP display switch 90b for displaying the current ORP on the display screen unit 80, and an integration up to that point on the display screen unit 80. A switch display switch 90c for displaying the flow rate and the total effective water amount, a strong alkaline water switch 90d for instructing alkaline water generation in the strong alkaline water generation mode, and alkaline water in each alkaline water generation mode A first alkaline water switch 90e, a second alkaline water switch 90f, and a third alkaline water switch 90g for instructing generation, and a water purification switch for instructing that water is allowed to pass through without being electrolyzed as the water purification mode. 90h, acidic water switch 90i for instructing the generation of acidic water in the acidic water generation mode, Sanitary water switch 90j for instructing the production of sanitary water in the raw water production mode, a first life setting switch 90k for setting the life of the first water purification cartridge 21, and a first for setting the life of the second water purification cartridge 22. This is a configuration comprising a two-life setting switch 90l and a reset switch 90m for resetting the integrated flow rate and the total effective water amount.

  The power switch 90a is an effective switch regardless of the state of the ion water generator. However, even if the power switch 90a is pressed, if a process that is in the middle of processing, such as wastewater treatment, is not completed, use a software-controlled power switch that ends those processes and turns off the power. Is preferred.

  The changeover display switch 90c is for displaying the integrated flow rate that is not displayed on the display screen unit 80 in the normal state and the total effective water amount that is normally displayed only during the generation state of the target water that can be consumed at a desired time. For example, the switch is set so that the integrated flow rate is displayed on the display screen unit 80 for a predetermined time, when the first press is performed, and the total effective water amount is displayed when the second press is performed.

  The strong alkaline water switch 90d is a switch for instructing the generation of strong alkaline water as the strong alkaline water generation mode. Strong alkaline water is, for example, pH 10.5, and can be used for boiled food, acupuncture, vegetable bowls, and the like.

  The first alkaline water switch 90e is a switch for instructing generation of alkaline water having a first pH level, for example, ph 9.5, as the first alkaline water generation mode. This level of alkaline water can be used for cooking, tea, and the like, for example. The second alkaline water switch 90f is a switch for instructing generation of alkaline water having a second pH level, for example, pH 9.0, as the second alkaline water generation mode. This level of alkaline water can be used, for example, for cooking rice. Further, the third alkaline water switch 90g is a switch for instructing generation of alkaline water at a third pH level, for example, pH 8.5, as the third alkaline water generation mode. This level of alkaline water can be used, for example, as drinking water.

  On the other hand, the acidic water switch 90i is a switch for instructing the generation of acidic water, for example, pH 5.5 water, as the acidic water generation mode. The acidic water is used for, for example, face washing, boiled noodles, tea astringent, etc. Can be used. The sanitary water switch 90j is a switch for instructing generation of strongly acidic sanitary water, for example, pH 2.5 water, as the sanitary water generation mode.

  The first alkaline water switch 90e, the second alkaline water switch 90f, the third alkaline water switch 90g, the acidic water switch 90i, the strong alkaline water switch 90d, the water purification switch 90h, and the sanitary water switch 90j are currently selected and effective. The built-in illumination in the switch is turned on and is visible to the user.

  The first life setting switch 90k is for setting the life of the first water purification cartridge 21. When the cartridge is replaced with a cartridge of a different type from the cartridge used so far, In response to the fact that the amount of water passing through the life varies depending on the type, notification of an appropriate replacement time can be performed by setting. The second life setting switch 90l is the same as the first life setting switch 90k, and is different only in that it corresponds to the second water purification cartridge 22.

  When the water purification cartridge is replaced, the reset switch 90m resets the integrated flow rate that has been counted so far in correspondence with the water purification cartridge before the replacement. An instruction to clear is given. The reset switch 90m is also used as a switch for resetting the total effective water amount obtained by summing up the effective water amounts calculated by the calculation unit 71. For example, in the case of resetting the total effective water amount, the switch is normally pressed, In the case of resetting the integrated flow rate corresponding to the cartridge, it is properly used by pressing and holding the switch.

  Next, the water generation mode in the water treatment apparatus according to the present embodiment will be described. The strong alkaline water production mode, the first alkaline water production mode, the second alkaline water production mode, the third alkaline water production mode, the purified water mode, the acidic water production mode, and the sanitary water production mode, which are water production modes in the present embodiment. Each generation mode is selected based on an operation by a user of each switch of the operation display unit 90 corresponding to each generation mode, and each target water is generated along with water flow.

  In the alkaline water generation mode, the electromagnetic valve 53 is opened under the control of the control unit 70 during water flow, and the purified water passes through the calcium addition tube 42 and proceeds from the electrolytic cell channel 44 to the electrolytic cell 60, and the electrolytic cell. In 60, a voltage is applied so that the second electrode plate 62 and the third electrode plate 63 serve as cathodes and the first electrode plate 61 serves as an anode under the control of the control unit 70. In each alkaline water generation mode, the applied voltage is different, and the strong alkaline water generation mode, the first alkaline water generation mode, the second alkaline water generation mode, and the third alkaline water generation mode are in descending order of the applied voltage.

  Among the alkaline water generation modes, in the first alkaline water generation mode, the second alkaline water generation mode, and the third alkaline water generation mode in which the generated alkaline water as target water may be used for drinking, it is The effective water amount corresponding to the amount actually used out of the water discharged during water is calculated by the calculation unit 71 and displayed on the display screen unit 80. On the other hand, in the strong alkaline water generation mode, the strong alkaline water generated as the target water is not used for drinking, so that the integrated flow rate is counted, but the amount discharged from the water discharge port 17 is actually used. The corresponding effective water amount is not particularly calculated and displayed on the display screen unit 80.

  In the water purification mode, when water is passed, the electromagnetic valve 53 is in a closed state and no voltage is applied to the electrode plates 61, 62, 63, and the purified water passes through the calcium addition tube 42 from the electrolytic cell channel 44. Proceeding to the electrolytic bath 60, it passes through the electrolytic bath 60 as it is, reaches the water discharge passage 16, and the purified water is discharged from the water discharge port 17 as the target water. In this case, the electromagnetic valve 53 is closed, so that water is not discharged from the discharge port 63 wastefully. Even in this water purification mode, the effective amount of water corresponding to the amount of water actually used for drinking out of the water discharged during water flow is calculated by the calculation unit 71 and displayed on the display screen unit 80.

  In the acidic water generation mode and the sanitary water generation mode, the second electrode plate 62 and the third electrode plate 63 are set as anodes and the first electrode plate 61 is set as a cathode under the control of the control unit 70, contrary to the alkaline water generation mode. A voltage is applied so that In particular, in the sanitary water generation mode, the purified water passes through the salt addition tube 41, reaches the electrolytic cell 60 in a state where salt is mixed in the water, and generates strongly acidic water as a high current value in the electrolytic cell 60. When the salt in the salt-added tube 41 is completely dissolved, the concentration of the salt is gradually reduced, so that the current value is reduced and the production efficiency of the strongly acidic water is reduced. In order to obtain a desired amount of sanitary water, the user puts the salt into the salt addition tube 41 and operates it as necessary.

  In these acidic water generation mode and sanitary water generation mode, since the generated acidic water and sanitary water are not used for drinking, the integrated flow rate is counted by the control unit 70 but is discharged from the spout 17. The effective water amount corresponding to the water amount is not particularly calculated by the calculation unit 71 and displayed on the display screen unit 80.

  The operation control states during the generation of water in each of these generation modes include a standby state, a drainage state, a discarded water state, a washing state, a generation stop state, a retry state, and a rinse state.

  The standby state corresponds to a state immediately after the power switch 90a of the operation display unit 90 is pressed and the water treatment apparatus 1 is started from a power-off state where power is not turned on. In this state, water flow at a level that can be detected by the flow sensor 30 is not performed, and the electromagnetic valve 53 is closed. Even when the power is turned off from the standby state, the solenoid valve 53 remains closed and water is not discharged from the discharge port 19 unnecessarily.

  The drainage state is a state in which the electromagnetic valve 53 is opened and the accumulated water is drained when water is not passed through for a predetermined amount of water or for a predetermined time in the standby state. This prevents water from stagnating in each of the addition cylinders 41 and 42, the electrolytic cell 60, and each flow path when shifting from another state to a standby state, and preventing germs and the like in the retained water from growing over time. Therefore, when the electromagnetic valve 53 is opened in a state where there is no water flow, water can flow out from the electrolytic cell channel 44 through the check valve 15 to the discharge channel 18, and the electrolytic cell 60, each addition cylinder, etc. The water staying in the water will be discharged. The transition from the standby state to the drained state and the return to the standby state after the drainage is completed are performed every predetermined time, and the mechanism is designed to ensure the drainage of stagnant water that serves as a hotbed for growth of germs and the like. Even when water flow is stopped and water is stopped from the water generation state in the water purification mode, the state is shifted to this drainage state.

  The waste water state is the start of water flow in each generation mode, and when there is a problem when the accumulated water in the apparatus is discharged and used as it is, especially when the state immediately before water flow is a standby state for a predetermined time or more. Alternatively, in the drained state, prior to water generation, the electromagnetic valve 53 is opened and the accumulated water is discarded for a predetermined set amount or a predetermined set time. By opening the electromagnetic valve 53 in a water-flowing state, water does not flow from the electrolytic cell channel 44 to the discharge channel 18 via the check valve 15, and water passes through the electrolytic cell 60 from the electrolytic cell channel 44. Thus, it flows out from the discharge channel 18 and the water discharge channel 16. After the waste water in the discarded water state is completed, the process proceeds to the generation state of each generation mode.

  In this discarded water state, a warning is displayed on the display screen unit 80, a warning sound is output, etc., in order to prevent the user from accidentally using the water discharged from the spout 17. In addition, the user may be reminded that the user should not use the water by lighting or flashing the lamp. For example, the illumination units of the switches 90d to 90j other than the display screen unit 80 may be connected simultaneously. For example, lighting or blinking, or providing a multicolor LED as an illuminating unit for each of the switches 90d to 90j, lighting the green state for the generated state, red for the discarded water state, and yellow for the retry state, and the like. Further, in the discarded water state, although water comes out from the spout 17, the calculation and display of the effective water amount as the target water that can be used for drinking and the like is not performed because the water cannot be used. In other words, the effective amount of water is not displayed even though the water is discharged from the spout 17, so that the user can recognize that this water is waste water, and a kind of warning means to the user. As a role.

The said washing | cleaning state is a state which wash | cleans the inside of the electrolytic vessel 60, when water flow is stopped from a production | generation state and it stops water in alkaline water production | generation mode. In this cleaning state, the electromagnetic valve 53 is closed, and the second electrode plate 62 and the third electrode plate 63 that have become cathodes in the generation state of the alkaline water generation mode are used as anodes, and the first electrode plate 61 is also used as anodes to cathodes. A voltage is applied for a predetermined time. Thereby, the scale etc. which adhered to each electrode plate 61, 62, 63 can be removed, and the next ionic water production | generation can be performed smoothly. In this case, by closing the electromagnetic valve 53, water does not flow from the electrolytic cell channel 44 to the discharge channel 18 via the check valve 15, and the electrolytic cell 60 is sufficiently filled with water. Can be washed in the wet state. When the voltage application for the predetermined time is completed, the accumulated water contains impurities such as the removed scale. Therefore, in order to surely drain the accumulated water, it normally shifts to the drained state. When the water flow operation is performed immediately, the state does not shift to the drained state but shifts to the discarded water state.
In the purified water mode and the acidic water generation mode, when the water flow is stopped from the generation state and the water is stopped, the state is shifted to the drainage state.

  The generation stop state is a state in which the electrolysis in the electrolytic cell 60 is stopped while the electromagnetic valve 53 is closed when a predetermined time has elapsed from the start of the generation state in the alkaline water generation mode and the acidic water generation mode. Even if the generation is stopped, water continues to flow out of the water discharge channel 16 if the water flow continues. Although water comes out from the spout 17 in this way, the amount of water used is not calculated and displayed for water that is not suitable for use. In the alkaline water generation mode, after shifting to the generation stop state, if the water flow is stopped and the water is stopped, the state is shifted to the washing state. On the other hand, in the acidic water production mode, if the water is stopped in this production stop state, it normally shifts to a drainage state. Transition to the water state.

  In the rinsing state, after a predetermined time has elapsed from the start of the sanitary water generation mode, the electromagnetic valve 53 is opened and water is passed through the electrode plates 61, 62, 63 without applying voltage to the electrolytic cell. 60 is a state of rinsing. In the production state of the sanitary water production mode, compared with the case where normal water is electrolyzed in the electrolytic bath 60, the salt has mixed into the water, so that the current value is high. However, when the salt in the salt-added cylinder is completely dissolved, the concentration of the salt is gradually decreased, so that the current value is decreased. When the concentration of the salt is reduced to a predetermined current value, the generation state (no salt) is shifted to while the generation of sanitary water is continued. In addition, even when a predetermined voltage is not applied even if a predetermined voltage is applied to the electrode plate from the beginning of the generation state in the sanitary water generation mode, the state shifts to the generation state (no salt). This generated state (no salt) is a state in which there is no salt in the salt addition tube 41, the water in the electrolytic bath 60 is not a salt solution of a predetermined concentration, and electrolysis is not performed smoothly. In this case, too, the rinsing state is entered after a predetermined time has elapsed.

  After a predetermined time has elapsed since the start of the sanitary water generation mode, for example, when 5 minutes have elapsed, the transition to the rinsing state is made. This is because it can be estimated that it has been generated, and the setting of this elapsed time may be changed. After the transition to the rinsing state, if the water is stopped, the state is shifted to the drainage state. If the water passage state is maintained without stopping the water and a predetermined period elapses, the electromagnetic valve 53 is closed and the generation stop state is closed. If water is stopped in this production stop state, the state normally shifts to a drained state, but if a water flow operation is performed immediately, the state is shifted to the discarded water state without shifting to the drained state.

  The retry state is an overcurrent or an undercurrent in the electrolytic cell 60 during a production state in a production mode in which electrolysis is performed in the electrolytic cell 60, such as an alkaline water production mode, an acidic water production mode, or a sanitary water production mode. In this case, as a rule, the state has been shifted to a state in which ionic water is not generated. In this retry state, a voltage is applied to the electrode plates 61, 62, 63 at a predetermined time interval to test whether an overcurrent or an undercurrent occurs in the electrolytic cell 60. Then, when the trial is successful, it returns to the generation state again. The transition to the retry state when overcurrent or undercurrent is generated in the electrolytic cell in this generated state is only when the predetermined retry condition is satisfied, and a state in which an abnormality that makes no sense of retry has occurred, etc. When the retry condition is not satisfied, the process shifts to a generation stop state in which the solenoid valve 53 is closed. In the case of shifting to the generation stop state, if the water stops, the state shifts to the drained state.

  In this retry state, since water continues to flow, although water comes out from the spout 17, it is not normally generated water, so that the effective water amount is calculated by the calculation unit 71 and the display screen unit 80. The effective water amount is not displayed in

  In each of the generation modes, after the generation state ends, when the time that can be continuously shifted to the generation state is exceeded, the generation state is shifted to the generation state through the discarded water state. This is to discharge the accumulated water. When the control unit 70 passes water for the first time after turning on the power, or when a predetermined time has elapsed since the water stoppage, the control unit 70 discards the first amount of water and passes the water before the predetermined time has passed since the water stoppage. In the case of water, a second amount of water is discarded. The amount of the first water coincides with the internal volume of the water treatment apparatus, and thus the waste water for the internal volume of the apparatus is discharged, so that the accumulated water is wiped out and bacteria and the like are propagated in the accumulated water. Can also be reliably removed. Further, the second amount of water coincides with the inner capacity of the electrolytic cell 60, and thus impurities such as the scale of the electrolytic cell 60 can be eliminated.

  In this way, the amount of discarded water was changed before and after the lapse of a predetermined time, because miscellaneous bacteria that propagate in the water multiply at a stretch over time, so that the number of bacteria in the water is low within a predetermined time In addition to being able to be removed sufficiently even if the amount of discarded water is reduced, the transition to the production state can be made quick to shorten the waiting time of the user, and further water saving can be realized.

  Further, when the control unit 70 does not shift from the water stop state to the generation state but directly changes from the generation state of a certain generation mode to the generation state of another generation mode, the first and second water amounts are Perform different wastewater controls. That is, 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 third water amount is discarded. Moreover, when shifting from the production state of the alkaline water production mode to the production state of the acidic water production mode or the production state of the purified water mode, or the production state of the acidic water production mode or the production of the alkaline water production mode from the production state of the purified water mode When shifting to the state, the fourth amount of water is discarded.

  The amount of the third water coincides with the inner volume of the electrolyzer 60, whereby the acidic water remaining as the staying water is not discharged as the water used by the user, and only the generated water in the designated mode is discharged. Can be provided to the user. On the other hand, the amount of the fourth water is less than the internal capacity of the electrolytic cell 60, and thus, the amount of discarded water is smaller than the amount of the third water. This is to avoid the water that is directly consumed being acidic water. That is, water discharged from the spout 17 in the production state of the alkaline water production mode is always used as alkaline water, so that the amount of discarded water has a margin, whereas in the acidic water production mode, there is a margin. Since there is little need for the amount of discarded water, the amount of discarded water is set so that alkaline water is not discharged. By making the wastewater as small as possible, the transition from the wastewater state becomes faster and at the same time water saving is realized.

  In addition, when the control unit 70 transitions from the sanitized water generation mode generation state to the next mode through a rinsing state that reduces the salt concentration mixed into the water to be treated in the electrolytic bath 60, the rinsing is completed. If the rinsing has not been completed, the sixth water is discarded.

  The sixth water amount is substantially equal to the internal volume of the ion water generating device, whereas the fifth water amount is an amount that does not satisfy the internal volume of the electrolytic cell 60. In this way, when rinsing has been completed and when rinsing has not been completed, the amount of discarded water has been changed for alkaline water and purified water that can be used for beverages. In addition, it is not desirable to use water containing salt even if it is acidic water, so it is desirable that the rinsing is completed reliably. In case of shifting to a drained state, etc., rinsing is incomplete, and it is necessary to complete rinsing, but if water is stopped, rinsing cannot be performed, In order to cope with this, the sixth water amount is sufficiently discarded in the discarded water state when the next water flow is performed, and this incomplete rinsing is compensated.

  On the other hand, when the mode is shifted from the mode other than the sanitary water generation mode to the sanitary water generation mode, the seventh water amount is discarded. The seventh amount of water is approximately the same as the fourth amount of water. As with acid water, sanitary water is used as the amount of water flow, because it is not necessary to make enough discarded water.

  Furthermore, the target water generation and discharge operation and the effective water amount calculation / display state in the water treatment apparatus according to the present embodiment will be described. As a premise, when the water treatment apparatus 1 can be turned on, when the user presses the power switch 90a of the operation display unit 90, the water treatment apparatus 1 first shifts to a standby state in the water purification mode that is set at the time of factory shipment. The selected state is indicated by the lighting of the water purification switch 90h.

  First, when the user desires alkaline water at the third pH level (pH 8.5) for drinking, the user presses the third alkaline water switch 90g and opens the water tap 12 to pass water. At this time, in response to the switch operation, the standby state of the purified water mode shifts to the standby state of the alkaline water generation mode, and the illumination of the third alkaline water switch 90g is turned on instead of the purified water switch 90h. And the calculation part 71 of the control part 70 recognizes that it is an alkaline water production | generation mode, reads conditions, such as the waste_water | drain ratio of the acidic water previously stored in the memory | storage part 72, the amount of discarded water, etc. based on these The effective amount of alkaline water as the target water can be calculated.

  For example, in the production state in the alkaline water production mode, when the total flow rate acquired by the flow sensor is 1000 ml, alkaline water and acidic water are produced at a ratio of 4: 1 in the electrolytic bath 60, so that the alkaline water is 800 ml. It is obtained and this is the amount discharged from the water outlet, but about 300 ml of water discharged first is not used as waste water, and the official alkaline water is 500 ml. However, the entire amount of alkaline water discharged is not used, and part of it is used for rinsing cups, etc., so this loss is expected to be about 1/10, and finally 450 ml is actually consumed, etc. The amount used is recognized as the amount used, and the effective water amount is calculated from the flow rate at the flow rate sensor 30 at such a ratio (see FIG. 4).

  In the operation in the alkaline water generation mode, after the transition from the water purification mode, the water is continuously passed without taking time, so that the operation shifts to the discarded water state without shifting to the drained state. In this discarded water state, the first water flow is performed after the power is turned on, and therefore the first amount of discarded water is discharged under the control of the control unit 70. In accordance with the water flow, the control unit 70 starts counting the integrated flow based on the output of the flow sensor 30. Note that water does not flow in the direction of the discharge flow path 18 through the check valve 15 because of the water flow state.

  While water is being discarded, the solenoid valve 53 is opened and water is discharged from both the water discharge channel 16 and the discharge channel 18, and the water discharged from the warning display portion of the display screen 80 is waste water. During the display, the calculation unit 71 does not calculate the effective water amount and the display screen unit 80 does not display the effective water amount, but the calculation unit 71 calculates the amount of waste water. Therefore, it is determined whether or not the amount of water has reached the first amount of water as the set amount.

  From the total amount of water based on the output of the flow sensor 30 and the proportion of discarded water occupying this, when the calculation unit 71 determines that the first amount of water has been discharged and discharged as discarded water and the discarded water state has ended, Control is performed by the control unit 70 to shift from the discarded water state to the generated state, and with the solenoid valve 53 open, the voltage is set so that the first electrode plate 61 is the anode and the second electrode plate 62 and the third electrode plate 63 are the cathode. Is applied.

  As a result, electrolysis of water proceeds in the electrolytic bath 60, and cations such as magnesium ions, sodium ions, potassium ions, and calcium ions are attracted to the second electrode plate 62 and the third electrode plate 63, which are the hydroxide ions. Anions such as sulfate ion, nitrate ion and chlorine ion are attracted to the first electrode plate 61 of the anode, and alkaline water is generated in the first electrolysis chamber 65 and the fourth electrolysis chamber 68, and the second electrolysis chamber 66 and Acidic water is generated in the third electrolysis chamber 67. Then, while the alkaline water is discharged from the water discharge port 17 through the water discharge channel 16, the acidic water is discharged through the discharge channel 18.

  Along with the transition to the generation state, the control unit 70 displays on the display screen unit 80 that drinking is possible, and the calculation unit 71 changes the flow rate obtained by the flow rate sensor 30 to the amount actually discharged from the alkaline water. The corresponding effective water amount is calculated, and the obtained effective water amount is displayed on the display screen unit 80 as the usage amount. When alkaline water discharge continues with continuous water flow, the value of the effective water amount calculated based on the flow rate value from the flow sensor 30 also increases, and the display value of the effective water amount as the usage amount on the display screen unit 80 also increases. It gradually increases.

  When the user uses a desired amount (eg, 200 ml) of alkaline water to be sprinkled for drinking, etc., when the water faucet 12 is closed and the water flow is stopped, the water transitions to the washing state and the water flows. With the stop, the control unit 70 stops counting the integrated flow rate, and the calculation of the effective water amount in the calculation unit 71 is also stopped. Then, each value of the integrated flow rate and the effective water amount (200 ml) up to this point is stored in the storage unit 72. The value of the effective water amount displayed on the display screen unit 80 is stopped after displaying the final value (200 ml) for a while.

  In the cleaning state, the scales and the like attached to the second electrode plate 62 and the third electrode plate 63, which were the cathodes when the alkaline water was generated, are peeled off and become floating in the water in the first electrolysis chamber 65 and the fourth electrolysis chamber 68. . After this cleaning state, the state is shifted to a draining state, and the electromagnetic valve 53 that is closed in the cleaning state is opened, and water mixed with impurities such as scale is allowed to pass from the electrolytic cell channel 44 through the check valve 15 to the discharge port 19. Drain from. 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.

  Subsequently, when the user desires acidic water (pH 5.5) for use in face washing or the like, the user presses the acidic water switch 90i, opens the water tap 12 and passes water. At this time, simultaneously with the switch operation, the alkaline water generation mode standby state is shifted to the acidic water generation mode standby state, and the illumination of the acidic water switch 90i is turned on instead of the third alkaline water switch 90g. And the calculation part 71 of the control part 70 recognizes that it is an acidic water production | generation mode, and reads conditions, such as the drainage rate of the alkaline water previously stored in the memory | storage part 72, the amount of discarded water, but does not drink acidic water. Therefore, the effective amount of acidic water is not calculated.

  In the operation in the acidic water generation mode, after the transition from the alkaline water generation mode, water is continuously passed from the standby state without taking time, so that the operation shifts to the discarded water state without shifting to the drainage state. While the water is being discarded, the electromagnetic valve 53 is opened, water is discharged from both the water discharge channel 16 and the discharge channel 18, and the control unit 70 starts counting the integrated flow rate in accordance with the water flow. Note that water does not flow in the direction of the discharge flow path 18 through the check valve 15 because of the water flow state. In this acidic water generation mode, since it is not drinkable regardless of whether it is waste water or not, there is no indication that the water discharged on the display screen unit 80 is not used for drinking as waste water. While the waste water comes out so that it can be used appropriately, a notification to that effect or a flashing of a part of the display screen unit 80 is given.

  In the discarded water state, when the predetermined time has elapsed since the end of the previous alkaline water generation, that is, when a predetermined amount of time has passed, the first amount of discarded water is discharged, and from the end of the previous alkaline water generation, that is, the stoppage of water. When it is before the predetermined time has passed from the water, the second amount of discarded water is discharged. In this acidic water generation mode, calculation of the effective water amount by the calculation unit 71 and display of the effective water amount on the display screen unit 80 are not performed, but the calculation unit 71 calculates the amount of waste water, and this water amount is It is determined whether or not the first water amount or the second water amount as the set amount has been reached.

  From the flow rate based on the output of the flow rate sensor 30, the known amount of discarded water discharged from the outlet 17 and the ratio of the amount of water discharged from the outlet 19 to the total amount, etc. If it is determined that the second amount of water is discharged and discharged as discarded water and the discarded water state is finished, the control unit 70 controls to move to the acidic water generation state, and the electromagnetic valve 53 remains open while the first electrode is open. A voltage is applied so that the plate 61 is a cathode and the second electrode plate 62 and the third electrode plate 63 are anodes.

  As a result, electrolysis of water proceeds in the electrolytic bath 60 and acidic water is generated in the first electrolysis chamber 65 and the fourth electrolysis chamber 68 by drawing the cation to the cathode and the anion to the anode, respectively. Alkaline water is generated in the second electrolysis chamber 66 and the third electrolysis chamber 67. The acidic water is discharged from the water discharge port 17 through the water discharge channel 16, while the alkaline water is discharged through the discharge channel 18. Along with the transition to the generation state, the control unit 70 displays on the display screen unit 80 that the acidic water can be used, but the effective amount of acidic water is not displayed.

  After the user uses the desired amount of acid water discharged to wash the face, etc., the water faucet 12 is closed to stop the water flow. Then, the counting of the integrated flow rate is stopped, and the integrated flow rate up to this point is stored in the storage unit 72. In the drained state, the accumulated water is drained from the discharge port 19 through the electrolytic cell channel 44 via the check valve 15. 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.

  Subsequently, when the user again desires the alkaline water at the third pH level (pH 8.5) for drinking, the user presses the third alkaline water switch 90g and opens the water tap 12 to pass water. At this time, simultaneously with the switch operation, a transition is made from the standby state of the acidic water generation mode to the standby state of the alkaline water generation mode, and the illumination of the third alkaline water switch 90g is turned on instead of the acidic water switch 90i. And the calculation part 71 of the control part 70 recognizes that it is an alkaline water production | generation mode similarly to the above, reads the conditions memorize | stored in the memory | storage part 72, and the state which can calculate the effective water amount of alkaline water based on this It becomes.

  In the operation in the alkaline water generation mode, after the transition from the acidic water mode, the water is continuously passed from the standby state without taking time, so the transition to the discarded water state is performed without shifting to the drained state. In this discarded water state, from the end of the previous generation of acidic water, that is, when a predetermined time has elapsed since the water stoppage, the first amount of water is discarded and before the predetermined time has elapsed since the water stoppage. In that case, the second amount of water is discarded. In accordance with the water flow, the control unit 70 starts counting the integrated flow rate. Note that water does not flow in the direction of the discharge flow path 18 through the check valve 15 because of the water flow state.

  While the water is being discarded, the solenoid valve 53 is opened, water is discharged from both the water discharge channel 16 and the discharge channel 18, and the water discharged from the display portion of the display screen 80 is drunk with the discarded water. During this time, the calculation unit 71 does not calculate and display the effective water amount, but the calculation unit 71 calculates the amount of waste water, and this water amount is used as the set amount. It will be determined whether or not the first water amount or the second water amount has been reached.

  While the water is discharged and discharged as discarded water, the calculation unit 71 calculates the total flow rate based on the output of the flow sensor 30, the amount of water discharged from the discharge port and the amount of water discharged from the discharge port in a known total amount. If it is determined from the ratio that the predetermined amount of the first water amount or the second water amount is discarded and the discarded water state is finished, the control unit 70 controls to shift to the alkaline water generation state, and the solenoid valve 53 A voltage is applied so that the first electrode plate 61 serves as an anode and the second electrode plate 62 and the third electrode plate 63 serve as a cathode.

  As a result, electrolysis of water proceeds in the electrolytic bath 60, the cation is attracted to the cathode, the anion is attracted to the anode, and alkaline water is generated in the first electrolysis chamber 65 and the fourth electrolysis chamber 68. Acidic water is generated in the second electrolysis chamber 66 and the third electrolysis chamber 67. Then, while the alkaline water is discharged from the water discharge port 17 through the water discharge channel 16, the acidic water is discharged through the discharge channel 18.

  Along with the transition to the generation state, the control unit 70 displays that it is drinkable on the display screen unit 80, and the calculation unit 71 is alkaline water corresponding to the amount actually discharged from the flow rate obtained by the flow rate sensor 30. The effective water amount is calculated and the obtained effective water amount is displayed on the display screen unit 80 almost simultaneously. Then, the total effective water amount combined with the last drinkable effective water amount (200 ml) is separately displayed on the display screen unit 80.

  After the user has used the desired amount of alkaline water to be discharged (eg 150 ml) for drinking, etc., the water faucet 12 is closed and the water flow is stopped. The control unit 70 stops counting the integrated flow rate, and the calculation of the effective water amount in the calculation unit 71 is also stopped. And the integrated flow volume and total effective water amount (200 + 150 = 350 ml) until this time are each memorize | stored in the memory | storage part 72. FIG. The values of the effective water amount and the total effective water amount displayed on the display screen unit 80 are stopped after displaying the final values (150 ml, 350 ml) for a while.

  In the cleaning state, as described above, the scale and the like attached to each electrode plate that is the cathode is peeled off and becomes floating in the water in the first electrolysis chamber 65 and the fourth electrolysis chamber 68. After this cleaning state, the state is shifted to a draining state, and the electromagnetic valve 53 that is closed in the cleaning state is opened, and water mixed with impurities such as scale is allowed to pass from the electrolytic cell channel 44 through the check valve 15 to the discharge port 19. Drain from. 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.

  In the state where the third alkaline water generation mode is still selected, when the user desires alkaline water again for drinking, the water tap 12 is newly opened and water is passed. The operation in this case is not performed because the time has not elapsed since the end of the previous alkaline water generation, that is, the water stoppage. In accordance with the water flow, the control unit 70 starts counting the integrated flow rate, shifts to the alkaline water generation state under the control of the control unit 70, and opens the first electrode plate 61 with the anode, A voltage is applied so that the second electrode plate 62 and the third electrode plate 63 serve as cathodes. As a result, alkaline water is generated in the first electrolysis chamber 65 and the fourth electrolysis chamber 68 of the electrolytic cell 60 as described above, and acidic water is generated in the second electrolysis chamber 66 and the third electrolysis chamber 67. Then, while the alkaline water is discharged from the water discharge port 17 through the water discharge channel 16, the acidic water is discharged through the discharge channel 18.

  Along with the transition to the generation state, the control unit 70 displays on the display screen unit 80 that drinking is possible, and the calculation unit 71 uses the effective amount of water corresponding to the amount of water actually drunk from the flow rate obtained by the flow rate sensor 30. And the obtained effective water amount is displayed on the display screen unit 80 at the same time. In the same manner as described above, the display screen unit 80 also displays the total effective amount of water combined with the total value (350 ml) of the effective amount of drinkable water up to the previous time.

  When the user uses the desired amount of alkaline water to be discharged (eg, 180 ml) for drinking, etc., the water faucet 12 is closed and the water flow is stopped. Accordingly, the control unit 70 stops counting the integrated flow rate, and the calculation of the usage amount in the calculation unit 71 is also stopped. And the integrated flow volume and total effective water amount (200 + 150 + 180 = 530 ml) until this time are each memorize | stored in the memory | storage part 72. FIG. The values of the effective water amount and the total effective water amount displayed on the display screen unit 80 are stopped after displaying the final values (180 ml, 530 ml) for a while.

  In the cleaning state, as described above, the scale and the like attached to each electrode plate that is the cathode is peeled off and becomes floating in the water in the first electrolysis chamber 65 and the fourth electrolysis chamber 68. After this cleaning state, the state is shifted to a draining state, and the electromagnetic valve 53 that is closed in the cleaning state is opened, and water mixed with impurities such as scale is allowed to pass from the electrolytic cell channel 44 through the check valve 15 to the discharge port 19. Drain from. 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.

  Subsequently, when the user desires purified water that is not ionic water for drinking or the like, the user presses the purified water switch 90h and opens the water tap 12 to pass water. At this time, simultaneously with the switch operation, the standby state of the alkaline water generation mode shifts to the standby state of the purified water mode, and the illumination of the purified water switch 90h is turned on instead of the third alkaline water switch 90g. And the calculation part 71 of the control part 70 recognizes that it is a purified water mode, reads conditions, such as a set amount of waste water corresponding to this purified water mode memorize | stored in the memory | storage part 72, and uses water based on this The amount can be calculated.

  For example, in the generation state in the purified water mode, when the total flow rate acquired by the flow sensor 30 is 1000 ml, all the purified water is discharged from the outlet without electrolysis in the electrolytic cell 60, and the discharged water amount is Although it becomes 1000 ml, about 300 ml of water discharged first is not used as waste water, and officially purified water is 625 ml. However, the entire amount of purified water discharged is not used, and some of it is used for rinsing cups, etc., so this loss is expected to be about 1/10, and finally about 563 ml is actually consumed, etc. The amount used is authorized, and the amount used is calculated from the flow rate at the flow rate sensor 30 at such a ratio.

  In the operation in the water purification mode, after the transition from the alkaline water generation mode, the water is continuously passed from the standby state without taking time, so the state is shifted to the discarded water state without shifting to the drained state. In this discarded water state, from the end of the previous alkaline water production, that is, when a predetermined time has elapsed since the water stoppage, the first amount of discarded water is made, from the previous alkaline water production end, If it is before the predetermined time has passed since the water stoppage, the second amount of water is discarded. In accordance with the water flow, the control unit 70 starts counting the integrated flow rate.

  While the water is being discarded, the solenoid valve 53 is opened, water is discharged from both the water discharge channel 16 and the discharge channel 18, and the water discharged at the display portion of the display screen 80 is the waste water. A warning requesting that it should not be used for drinking is made, and during this time, the calculation unit 71 does not calculate and display the effective water amount. When the calculation unit 71 determines that the predetermined amount of water is discharged and discharged as discarded water and the state of the discarded water is finished from the output of the flow sensor 30 or the like, the electromagnetic valve 53 is closed under the control of the control unit 70, and the electrolytic cell It moves to the production | generation state of the purified water which does not apply a voltage to each electrode plate of 60.

  The purified water is discharged from the water discharge port 17 through the water discharge channel 16. At this time, since the electromagnetic valve 53 is closed, water is not discharged through the discharge flow path 18, and water is not wasted. Along with the transition to the generation state, the control unit 70 displays that it is drinkable on the display screen unit 80, and the calculation unit 71 corresponds to the amount of water that is effectively discharged from the flow rate obtained by the flow rate sensor 30 as purified water. The effective water amount is calculated, and the effective water amount is displayed on the display screen unit 80 at the same time. In the same manner as described above, the total effective water amount combined with the total value (530 ml) of the effective water amount that can be drunk up to the previous time is separately displayed on the display screen unit 80.

  After the user has used the desired amount of purified water (eg, 250 ml) for drinking, etc., when the water faucet 12 is closed and the water flow is stopped, the water is transferred to a drained state, and the water flow is stopped. The control unit 70 stops counting the integrated flow rate, and the calculation of the effective water amount in the calculation unit 71 is also stopped. Then, the integrated flow rate up to this point and the total effective water amount (200 + 150 + 180 + 250 = 780 ml) are obtained and stored in the storage unit 72, respectively. About each value of the effective water amount and the total effective water amount displayed on the display screen part 80, after displaying a final value (250 ml, 780 ml) for a while, a display is stopped. In the drained state, the closed electromagnetic valve 53 is opened, and the accumulated water is drained from the discharge port 19 through the check valve 15. 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.

  Furthermore, when the user desires to use strong alkaline water (pH 10.5) as water for use in boiled foods, squeezes, or vegetable bowls, the strong alkaline water switch 90d is pressed and the water tap 12 is turned on. Open and pass water. At this time, simultaneously with the switch operation, the standby state of the purified water mode shifts to the standby state of the strong alkaline water generation mode, and the strong alkaline water switch 90d lights up instead of the purified water switch 90h. And the calculation part 71 of the control part 70 recognizes that it is a strong alkaline water production | generation mode, and since strong alkaline water is not drunk, the calculation of an effective water amount is not performed.

  In the operation in the strong alkaline water generation mode, after the transition from the water purification mode, the water is continuously passed from the standby state without taking time, so that the operation shifts to the discarded water state without shifting to the drainage state. While the water is being discarded, the electromagnetic valve 53 is opened, water is discharged from both the water discharge channel 16 and the discharge channel 18, and the control unit 70 starts counting the integrated flow rate in accordance with the water flow. Note that water does not flow in the direction of the discharge flow path 18 through the check valve 15 because of the water flow state. In this strong alkaline water generation mode, since it is not drinkable regardless of whether it is discarded water, the display screen unit 80 does not display that the water discharged from the display screen 80 is not used for drinking with discarded water. While the water is discharged so that the water can be used appropriately, a notification to that effect or a flashing of a part of the display screen unit 80 is given.

  In the discarded water state, when the predetermined time has elapsed since the end of the previous purified water generation, that is, when the predetermined amount of time has elapsed since the water stop, the first amount of water is discarded, and before the predetermined time has elapsed since the water stoppage. A second amount of water is discarded. In the strong alkaline water generation mode, the calculation unit 71 does not calculate the effective water amount and does not display the effective water amount on the display screen unit 80. However, the calculation unit 71 calculates the amount of waste water. It is determined whether the first water amount or the second water amount as the set amount has been reached.

  When it is determined from the total flow rate based on the output of the flow rate sensor 30 that the calculation unit 71 discharges and discharges the first water amount or the second water amount as waste water and the waste water state is finished, the control unit 70 Under the control, the voltage is applied so that the first electrode plate 61 is the anode and the second electrode plate 62 and the third electrode plate 63 are the cathode while the electromagnetic valve 53 is open. .

As a result, electrolysis of water proceeds in the electrolytic bath 60, and strong alkaline water is generated in the first electrolysis chamber 65 and the fourth electrolysis chamber 68 by drawing a cation to the cathode and an anion to the anode. Acidic water is generated in the second electrolysis chamber 66 and the third electrolysis chamber 67. Then, strong alkaline water is discharged from the water outlet 17 through the water discharge passage 16, while acidic water is discharged through the discharge passage 18.
At the same time as the transition to the generation state, the control unit 70 displays on the display screen unit 80 that strong alkaline water can be used, but the calculation unit 71 does not calculate and display the effective water amount.

  After the user uses a desired amount of strong alkaline water to be discharged, when the water tap 12 is closed and the water flow is stopped, the flow shifts to the cleaning state and the control unit 70 integrates the water flow stop. The counting of the flow rate is stopped, and the integrated flow rate up to this point is stored in the storage unit 72.

  In the cleaning state, as described above, the scale and the like attached to the electrode plates 62 and 63, which were the cathodes, are peeled off and become floating in the water in the first electrolysis chamber 65 and the fourth electrolysis chamber 68. After this cleaning state, the state shifts to a draining state. In the cleaning state, the closed electromagnetic valve 53 is opened, and water containing impurities such as scale is drained from the discharge port 19 via the check valve 15. 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.

  At the stage when the use of the strong alkaline water is finished, since the strong alkaline water is not potable water, the effective water amount and the total effective water amount are not displayed, but the user can operate the display screen unit 80 by operating the changeover display switch 90c. The total effective water amount (780 ml) can be displayed on the screen, and the amount used as potable water from the start of use to this point can be grasped.

  As described above, the water treatment apparatus according to the present embodiment uses the flow rate sensor 30 that measures the flow rate of water including ionic water or purified water as target water, and calculates the calculation unit 71 from the obtained flow rate information. Calculates the effective water amount corresponding to the amount actually used for the target water, and displays this effective water amount on the display screen unit 80. Start with reference to the timing when the wastewater state at the start of water supply ends and transition to the production state where the target water is produced, and the target water is used by the user when the user is actually using the target water. The amount of target water used can be easily displayed by displaying the effective water amount obtained by appropriately estimating the amount of target water used from the flow rate obtained by the flow sensor 30. Be sure to recognize the amount used for drinking, etc. The water usage can be managed appropriately, and the flow rate information from the flow sensor 30 that is not specialized for the target water is used for the purpose of counting the accumulated flow, and a measuring means such as a sensor is separately used for the target water. There is no need for additional arrangement, and the measurement system can be simplified.

  In addition, in the water treatment apparatus which concerns on the said embodiment, although the example of the ion water purifier provided with the water purifying part 20 is shown, in the water purifier which has not only this but only a water purifying function, a part which is not provided for use of waste water etc. It can also be set as the structure which calculates and displays appropriately the effective amount of purified water except for. In this case, similarly to the above, the calculation unit is not limited to calculating the amount of discarded water to determine the end of the discarded water state and the transition time to the generated state, but as a simpler structure, known water that is not used As information, a predetermined waiting time from the start of water flow, that is, a waiting time that can be regarded as the presence of purified water that does not have the possibility of mixing foreign substances such as germs after the elapse of the predetermined time, is given. The calculation unit may start calculating the effective amount of water and the display screen unit may start displaying on the basis of the time point. Furthermore, instead of displaying a warning on the display screen unit for preventing the user from accidentally using the discarded water, the user is allowed to recognize the unusable state by discharging water without displaying the effective water amount during the waiting time. In other words, the display can be simplified.

  Moreover, in the water treatment apparatus according to the embodiment, the effective water amount of drinking alkaline water or purified water in the target water is calculated, aggregated, and collectively displayed as the total effective water amount. May be calculated and displayed separately for alkaline water and purified water, respectively, or the alkaline water may be divided for each pH level to calculate and display the total effective water amount. Further, the calculation unit 71 also calculates the effective amount of each of the acidic water in the acidic water generation mode, the strong alkaline water in the strong alkaline water generation mode, and the sanitary water in the sanitary water generation mode. You may make it display on. However, when calculating the effective amount of acidic water and sanitary water, the flow rate ratio between the amount of water that is directed to the spout 17 and the alkaline water discharged from the discharge port 19 out of the total amount of water. Is calculated in consideration of the above.

  Moreover, in the water treatment apparatus according to the embodiment, the display of the effective water amount on the display screen unit 80 is a numerical display, but in addition to this, a graph display indicating the magnitude of the amount can be made by the length of the bar. .

  In the water treatment apparatus according to the embodiment, the calculation unit 71 calculates the amount of discarded water and determines the end of the discarded water state and the transition time to the generated state. When there is almost no change, simply use a timer to measure the known set time that elapses before the appropriate amount of wastewater is discharged, and determine the transition point from the wastewater state to the production state. You may make it determine.

(Second embodiment of the present invention)
A water treatment apparatus according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 8 is a front view of the main part of the display screen and operation unit of the water treatment apparatus according to the present embodiment, FIG. 9 is an explanatory diagram of the operation state of each part in the water treatment apparatus according to the present embodiment, and FIG. FIG. 11 is an operation state explanatory diagram in the case of including a reset operation of each unit in the water treatment apparatus according to the embodiment, and FIG. 11 is an operation state explanatory diagram in a case of including calculation / display stop operation of each unit in the water treatment apparatus according to the present embodiment.

  In each of the drawings, the water treatment apparatus according to the present embodiment is similar to the first embodiment in that the water supply pipe 11, the water purification unit 20, the flow sensor 30, the salt addition cylinder 41, the calcium addition cylinder 42, A path switching unit 51, an electrolytic cell 60, a water discharge channel 16, a discharge channel 18, a control unit 70, a display screen unit 80, and an operation unit 90 are provided. It has a configuration including a measurement start switch 91 that receives an instruction to start display of the effective amount of water.

  The calculation unit 71 of the control unit 70 stores the flow rate information output from the flow rate sensor 30 and the water generation mode selected by switch operation after the start of water flow, as in the first embodiment. Using the known information such as the set amount of discarded water read from the unit 72 and the ratio of the water discharged from the discharge port 19 to the total amount of water flowing through the flow rate sensor 30 unit, first from the same outlet 17 as the target water. Calculate the amount of discarded water to be discharged, compare this amount of discarded water with the set amount, and after the specified amount of discarded water has been discharged a predetermined amount of time after the start of water flow, the discarded water state ends and the target water To determine when to enter the generation state. At the time when the discarded water state is completed, the control unit 70 controls to move from the discarded water state to the target water generation state, and ionic water or purified water as the target water is discharged from the water outlet 17. Although the warning display of the discarded water state is completed or it is displayed that drinking is possible, the calculating unit 71 does not calculate the effective water amount.

  When the user who sees the warning display end or the drink-ready display on the display screen unit 80 operates the measurement start switch 91 to instruct the measurement start, the calculation unit 71 sets this point as the target water supply start point. The calculation of the effective water amount will be started. The obtained value of the effective water amount is output to the display screen unit 80, and the measurement display of the effective water amount is started almost simultaneously with the calculation on the display screen unit 80. However, in the display screen unit 80, as in the first embodiment, the effective water amount is displayed in the name of “used amount”, and when the previous effective water amount is stored in the storage unit 72, the total effective amount is displayed. The amount of water is also displayed under the name of “total usage”.

  Next, the alkaline water generation discharge operation and the effective water amount calculation / display state in the water treatment apparatus according to the present embodiment will be described. As a premise, in the state where the water treatment apparatus 1 can be turned on as in the first embodiment, when the user presses the power switch 90a, the water treatment apparatus 1 is temporarily switched to the standby state in the water purification mode, and this water purification mode has been selected. Is indicated by lighting of the water purification switch 90h. The generation mode of each water, the ratio of discarded water and waste water such as waste water and target water, and the amount of discarded water in each situation are the same as those in the first embodiment.

  The user pushes the third alkaline water switch 90g to open the water tap 12 and allows water to pass to drink alkaline water at the third pH level (pH 8.5). In response to this switch operation, the standby state of the purified water mode is shifted to the standby state of the alkaline water generation mode, and the illumination of the third alkaline water switch 90g is turned on instead of the purified water switch 90h. And the calculation part 71 of the control part 70 recognizes that it is an alkaline water production | generation mode, reads conditions, such as the waste_water | drain ratio of the acidic water previously stored in the memory | storage part 72, the amount of discarded water, etc. based on these The effective amount of alkaline water as the target water can be calculated.

  For example, in the production state in the alkaline water production mode, when the total flow rate acquired by the flow sensor 30 is 1000 ml, alkaline water and acidic water are produced in the electrolytic cell 60 at a ratio of 4: 1. 800 ml is obtained, and this is the amount discharged from the spout. Of this, about 300 ml discharged first is not used as discarded water, and the official alkaline water is 500 ml. As in the first embodiment, the entire amount of the discharged alkaline water is not used, and a part of the alkaline water is used for rinsing the cup. However, in this embodiment, the actual user is operated by the user's switch operation. Since it is possible to grasp the period of use, it is not necessary to allow for this loss, and when the flow sensor 30 obtains the flow rate value of 1000 ml while it is recognized that the user has used alkaline water by operating the switch Will be certified as the amount actually used for drinking, etc., except for the portion of acid water and waste water, and the amount used will be calculated from the flow rate at the flow sensor 30 at this rate. It is a mechanism to be done.

  In the operation in the alkaline water generation mode, after the transition from the water purification mode, water is continuously passed without taking time, so that the operation shifts to the discarded water state without shifting to the drained state. In this discarded water state, the first water flow is performed after the power is turned on, and therefore the first amount of discarded water is discharged under the control of the control unit 70. In accordance with the water flow, the control unit 70 starts counting the integrated flow based on the output of the flow sensor 30. In this water flow state, water does not flow in the direction of the discharge flow path 18 through the check valve 15.

  While the water is being discarded, the solenoid valve 53 is opened, water is discharged from both the water discharge channel 16 and the discharge channel 18, and the water discharged from the display portion of the display screen 80 is drunk with the discarded water. During this time, the calculation unit 71 does not calculate the effective water amount and the display screen unit 80 does not display the effective water amount, but the calculation unit 71 calculates the amount of waste water. Then, it is determined whether or not the amount of water has reached the first amount of water as the set amount. Even if the user erroneously operates the measurement start switch 55 in the discarded water state, the calculation of the effective water amount by the calculation unit 71 and the display of the effective water amount on the display screen unit 80 are not changed.

  When it is determined from the total amount of water based on the output of the flow sensor 30 and the ratio of discarded water in the total amount, the calculation unit 71 discharges and discharges the first amount of water as discarded water, and the discarded water state ends. Then, the control unit 70 makes a transition from the discarded water state to the generation state, and the first electrode plate 61 is used as an anode and the second electrode plate 62 and the third electrode plate 63 are used as cathodes while the electromagnetic valve 53 is open. Apply voltage.

  As a result, electrolysis of water proceeds in the electrolytic bath 60, the cations are attracted to the second electrode plate 62 and the third electrode plate 63 as the cathode, and the anions are attracted to the first electrode plate 61 as the anode. Alkaline water is generated in the electrolysis chamber 65 and the fourth electrolysis chamber 68, and acidic water is generated in the second electrolysis chamber 66 and the third electrolysis chamber 67. Then, while the alkaline water is discharged from the water discharge port 17 through the water discharge channel 16, the acidic water is discharged through the discharge channel 18.

  Along with the transition to the generation state, the control unit 70 displays on the display screen unit 80 that drinking is possible. When the user who sees this starts drinking water such as an operation of pouring alkaline water into a cup, and simultaneously operates the measurement start switch 55 to instruct the start of measurement, the calculation unit 71 receives this and the flow rate sensor The effective water amount corresponding to the amount of alkaline water actually discharged is calculated from the flow rate obtained at 30, and the obtained effective water amount is displayed on the display screen unit 80 as the usage amount.

  When the user uses a desired amount (eg, 200 ml) of alkaline water to be sprinkled, drinking water, etc., and then closing the water tap 12 to stop the water flow, the production state shifts to the washing state. When the water flow is stopped, the control unit 70 stops counting the integrated flow rate, and the calculation unit 71 also stops calculating the effective water amount. Then, each value of the integrated flow rate and the effective water amount (200 ml) up to this point is stored in the storage unit 72. The value of the effective water amount displayed on the display screen unit 80 is stopped after displaying the final value (200 ml) for a while.

  In the cleaning state, as in the first embodiment, the scale and the like attached to the second electrode plate 62 and the third electrode plate 63, which were the cathodes when the alkaline water was generated, peeled off, and the first electrolysis chamber 65 and the fourth electrolysis chamber. It becomes floating in 68 water. After this cleaning state, the state is shifted to a draining state, and the electromagnetic valve 53 that is closed in the cleaning state is opened, and water mixed with impurities such as scale is allowed to pass from the electrolytic cell channel 44 through the check valve 15 to the discharge port 19. Drain from. 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.

  In this embodiment, since the start of display of the effective water amount (usage amount) can be arbitrarily set by the measurement start switch 91 in the target water generation state, the effective value calculated by the calculation unit 71 by operating the reset switch 90m immediately before the start. If you reset the total effective water volume to 0, you can start calculating the next effective water volume and start counting the total effective water volume (total usage) from the beginning of the display (see Fig. 10). In addition, the starting points of the effective water amount (used amount) and the total effective water amount (total used amount) can be easily adjusted to the same time point.

  As described above, in the water treatment apparatus according to the present embodiment, the measurement start switch 91 that accepts the user's operation is arranged, and when this switch is operated, the calculation unit 71 uses the target time point as a reference to calculate the target water. The effective amount of water is calculated, and the display screen unit 80 displays the effective amount of water so that the user can grasp the amount of target water used. If the switch is operated by itself when actually starting, the calculation unit 71 can appropriately recognize the use period of the target water, and the effective water amount can be calculated and displayed as a value substantially matching the actual target water use amount. The user can be informed of the exact amount of water used.

  In the water treatment apparatus according to the embodiment, the calculation of the effective water amount of the target water started by the operation of the measurement start switch 91 and the stop of the display are performed in accordance with the end of the water flow by closing the water tap 12. Although not limited to this, a measurement stop switch 92 for receiving an operation for instructing stoppage of calculation and display of the effective amount of target water started by operation of the measurement start switch 91 is provided, as shown in FIG. In addition to the start, the end can be instructed by the user's switch operation. If the measurement stop switch 92 is operated to continue the water flow even after the end of drinking, the calculation unit keeps the water flow. The calculation of the effective amount of water at 71 and the display on the display screen unit 80 can be stopped, and after drinking, the appropriate amount of water can be calculated corresponding to the state of continuing to dispense water for use different from drinking, The amount of use who was drinking a can accurately grasp. The metering stop switch 92 can also be configured to be used as a metering start switch because the timing for instructing the stop does not overlap the timing for instructing the start.

  Moreover, in the water treatment apparatus which concerns on the said embodiment, although the example of the ion water purifier provided with the water purifying part 20 is shown, also in the water purifier which has not only this but only a water purifying function, it calculates on the basis of switch operation time.
