The water purification unit 2 comprising: a flow rate sensor C that measures the amount of water that has passed through the water purification unit 2, an additive mixing unit 50 that adds salt and calcium to the purified water, and the purified raw water is electrolyzed The electrolysis part 3 is provided and the water treatment flow path which can take out purified water, acidic water, and alkaline water from the discharge outlet 19c of the water pipe 19b is formed. In FIG. 1, 11a is a water tap and 11b is a branch plug provided on the downstream side of the water tap 11a. By operating a lever 11c of the branch plug 11b, tap water as raw water is adjusted to the water regulating device 1. The user can select whether the water is passed to the side or directly.

  Here, first, the whole structure of the water adjuster 1 which concerns on this embodiment is demonstrated concretely along the flow of water.

  In a state where the lever 11c is switched to the water conditioner 1 side, the raw water supplied to the water conditioner 1 side by the user operating the water tap 11a is first purified through the water conduit 11 and the water inlet 19a. Part 2 is reached.

  The purified water part 2 plays the role which produces | generates purified water by removing the fine impurities etc. which are contained in raw | natural water, and is comprised in the purified water tank 20 which consists of the upper cartridge 20a and the lower cartridge 20b. . The upper cartridge 20a and the lower cartridge 20b contain hollow fiber membranes, activated carbon, and the like, and can be individually replaced according to the degree of deterioration or the like.

  The raw water supplied to the water purification unit 2 becomes purified water and reaches the flow sensor C.

  The flow sensor C is electrically connected to the control unit 7 and plays a role of measuring the flow rate of purified water purified by the water purification unit 2 and transmitting the information to the control unit 7.

  The purified water that has passed through the flow sensor C reaches the additive mixing unit 50 that adds calcium and salt to the purified water.

  The additive mixing section 50 is connected to a flow path switching valve 80 that selectively switches the flow path of purified water flowing into the additive mixing section 50 in two directions, and one branch pipe that extends from the flow path switching valve 80. The calcium addition section 8, the salt addition section 9 connected to the other branch pipe extending from the flow path switching valve 80, the outlet pipe extended from the salt addition section 9, and the calcium addition section 8. And a check valve 70 interposed in the middle of the outlet pipe between the salt addition section 9 and the merging pipe section 60.

  The flow path switching valve 80 plays a role of switching the flow path of the water that has passed through the flow sensor C to the calcium addition part 8 side or the salt addition part 9 side. Specifically, the user can switch the flow path in either direction by operating a two-way selector switch 81 provided on the upper part of the flow path switching valve 80.

  The flow path switching valve 80 is electrically connected to the control unit 7 so that the flow path selected by the user by operating the two-way switch 81 can be detected by the control unit 7.

  The calcium addition part 8 enables supply of calcium into raw water to be supplied to the main electrolytic cell 30 described later, and a preparation for elution of calcium (for example, a calcined shell calcium preparation or a calcium preparation derived from salmon). Is housed.

  The salt addition unit 9 enables supply of salt into the raw water supplied to the main electrolytic cell 30, and the salt addition unit 9 accommodates the salt in the water passing through the salt addition unit 9. It is comprised so that a predetermined amount of salt can be dissolved.

  When the user operates the flow path switching valve 80 to select the flow path in the additive mixing part 50 as the calcium addition part 8, the check valve 70 is water that has passed through the calcium addition part 8 This is a valve for preventing the flow back to the adding portion 9 side. That is, salt is added to promote electrolysis in the electrolysis unit 3, but when the user desires water that does not require electrolysis (purified water), backflow occurs and salt is mixed into the purified water. It plays a role in preventing it.

  The purified water that has passed through the additive mixing part 50 flows into the electrolysis part 3. The electrolysis unit 3 is a first electrolysis unit 30 that electrolyzes purified water, and a second electrolysis unit that increases the concentration of dissolved hydrogen in alkaline water generated in the second electrode chamber 34 of the main electrolysis cell 30. It is comprised with the subelectrolyzer 40 which is. The main electrolyzer 30 and the sub electrolyzer 40 are configured so that a pair of electrodes having different polarities are opposed to each other, and function as an electrolyzer that electrolyzes water and generates alkaline water or acidic water.

  As shown in FIG. 1, the main electrolytic cell 30 is a first electrode provided with a first electrode 31 that becomes the anode side when discharging alkaline water in the present embodiment and becomes the cathode side when discharging acidic water. A partition 32 is formed between the chamber 32 and a second electrode chamber 34 provided with a second electrode 33 which becomes the anode side when discharging alkaline water and becomes the anode side when discharging acidic water. Yes. In the present embodiment, two each of the second electrode chamber 34 and the first electrode chamber 32 are provided in the main electrolytic cell 30, but the present invention is not particularly limited thereto.

  Further, a first water intake port 39 a is formed at the downstream end of the first electrode chamber 32, and a pipe for supplying water to the sub electrolytic cell 40 is connected thereto. Similarly, a second water intake port 39 b is also formed at the downstream end of the second electrode chamber 34, and a pipe for supplying water to the sub electrolytic cell 40 is connected thereto.

  The sub-electrolyzer 40 plays a role of increasing the concentration of dissolved hydrogen in the generated alkaline water, and the inside of the third electrode chamber 44 and the fourth electrode chamber, which are flat spaces through the electrochemical cell 43, is provided inside. And 45 are formed.

  A first water inlet 41 a is formed at the upstream end of the third electrode chamber 44, and a pipe extending from the first water inlet 39 a of the main electrolytic tank 30 is connected to connect the first electrode chamber 32. The passed water can flow into the third electrode chamber 44.

  Similarly, a second water inlet 41b is also formed at the upstream end of the fourth electrode chamber 45, and a pipe extending from the second water inlet 39b of the main electrolytic cell 30 is connected to the second electrode. Water that has passed through the chamber 34 can flow into the fourth electrode chamber 45.

  A first water outlet 42 a is formed at the downstream end of the third electrode chamber 44, and a drain pipe 12 b that extends downward from the casing 10 is extended to the first water outlet 42 a. ing.

  The drain pipe 12b is connected to a drain pipe 12a extending from the upstream end of the first electrode chamber 32 and the second electrode chamber 34, and when the supply of raw water is stopped, The water staying in the water can be discharged from the discharge port 51. Reference numeral 72 is a check valve that is provided in the middle of the drain pipe 12a and prevents the inflow of water from the drain pipe 12b toward the drain pipe 12a.

  Further, an electromagnetic valve 71 electrically connected to the control unit 7 is disposed in the vicinity of the discharge port 51 of the drain pipe 12b so that water discharge can be controlled. The electromagnetic valve 71 is provided in the middle of the discharge flow path connected to the electrolytic cells 30 and 40 and functions as a valve device that opens and closes in response to a command from the control unit 7 described later.

  On the other hand, a second water outlet 42b is formed at the downstream end of the fourth electrode chamber 45. A water intake pipe 19b is extended to the second water outlet 42b, and purified water is discharged from the outlet 19c at the tip. And electrolytic water, that is, acid water and alkaline water can be taken.

  It should be noted that the “water discharge conduit” in the water conditioner according to the present embodiment means from the electrolysis unit 3 to the discharge port 19c of the water intake pipe 19b, and has a volume of about 100 ml.

  Therefore, when the electrolyzed water discharged lastly remains in the water discharge pipe in the state where the water tap 11a is closed, when the water tap 11a is opened again and 100 ml of purified water is supplied to the electrolyzing unit 3. Almost all of the remaining electrolyzed water is expelled from the pipe flow path and discharged.

  As described above, the purified water sent from the additive mixing part 50 to the main electrolytic cell 30 is electrolyzed to generate acidic water and alkaline water. For example, when alkaline water is taken from the discharge port 19c The acidic water generated in the first electrode chamber 32 of the main electrolytic cell 30 is the first intake port 39a → the first water inlet port 41a → the third electrode chamber 44 → the first water outlet port 42a → the drain pipe 12b → the outlet port 51. On the other hand, the alkaline water generated in the second electrode chamber 34 of the main electrolytic cell 30 is the second water intake 39b → second water inlet 41b → fourth electrode chamber 45 → second water outlet 42b → water intake pipe 19b → It flows out of the discharge port 19c and flows out.

  At this time, when the electrochemical cell 43 of the sub-electrolysis tank 40 is energized, the acidic water is electrolyzed in the third electrode chamber 44 of the sub-electrolysis tank 40, and as shown in the reaction formula (1), oxygen and hydrogen And hydrogen ions pass through the ion exchange membrane 43a to the fourth electrode chamber 45, and the concentration of dissolved hydrogen in the alkaline water produced continuously can be increased. In the electrolysis in the sub-electrolysis tank 40, the current value of the electrolysis in the main electrolysis tank 30 was 4A, but it may be about 0.5A.

Reaction formula (1) 2H ₂ O → 4H ⁺ + 4e ⁻ + O ₂

  In the water conditioner 1 according to the present embodiment, the main electrolytic cell 30 and the sub electrolytic cell 40 can be individually controlled via the control unit 7. Specifically, the first electrode 31 and the second electrode 33 disposed in the main electrolytic cell 30 and the later-described electrochemical cell 43 disposed in the sub electrolytic cell 40 are controlled, for example, (1) Both energization of the main electrolyzer 30 and the sub electrolyzer 40 is ON, (2) both are OFF, (3) the main electrolyzer 30 is ON, the sub electrolyzer 40 is OFF, (4) the main electrolyzer Control such that 30 is OFF and the sub-electrolysis tank 40 is ON can be freely performed, and water having a desired property can be obtained. Also, the current value can be individually controlled, and the pH of the alkaline water can be changed, for example, in the range of 8 to 10, or the dissolved hydrogen concentration value can be changed.

  With the above configuration, the alkaline water and the acidic water, and further neutral water, that is, purified water can be taken in from the common main discharge port 19c by stopping energization of the main electrolytic tank 30. By the way, when the acidic water is taken from the discharge port 19c, the polarities of the electrodes 31 and 33 of the main electrolytic cell 30 are reversed. In this way, the water having the necessary properties can be selectively taken out from the common discharge port 19c, so that it is easy to use.

  As shown in FIG. 2, the operation and various settings for taking water of various properties with the water adjuster 1 are performed by operating the control unit 7 with the operation buttons B1 to B10 of the operation panel P provided on the side surface of the casing 10. Can be run through.

The larger the positive value, the greater the oxidation ability, and the larger the negative value, the more the reduction ability. large. Accordingly, the strength of the acid water and alkaline water can be confirmed from these numerical values. Here, when the ORP display button B2 is pressed, the current ORP value is digitally displayed on the display portion D.

  Further, when the water flow amount display button B3 is pressed, the current raw water flow amount into the water adjuster 1 is digitally displayed on the display unit D. Then, below the water flow amount display button B3, a strong alkaline water button B4, alkaline water buttons B5 to B7, a purified water button B8, and an acidic water button B9 are arranged in a vertical line. Alkaline water can be selected in three stages depending on the application.

  With such a configuration, the user can use the two-way selector switch 81 as necessary while normally using in a state in which alkaline water, which is considered to be good for health and to which calcium is added and the amount of dissolved hydrogen is increased, can be taken. The salt water is mixed into the raw water with a simple operation to increase the degree of electrolysis, and in this state, the acidic water button B9 and the strong alkaline water button B4 are operated to provide strong acidic water used for sanitary water, various washing waters, etc. It is possible to take in strongly alkaline water that can be used for

  When water is taken again after a time of 30 minutes or more and less than 8 hours has elapsed since the last water intake (hereinafter also referred to as water stoppage), a predetermined amount (this embodiment) regardless of the type of water taken last. In this case, the water is discarded (hereinafter referred to as condition X2). This condition X2 is for cleaning the inside of the electrode unit 104 and the piping.

  When water is taken again after the time of 8 hours or more has elapsed after the water stoppage, the water is discarded by a predetermined amount (1.0 L in this embodiment) regardless of the type of water taken last (hereinafter referred to as condition X3). .) This condition X3 is for more reliably cleaning the inside of the electrode unit 104 and the pipe when a longer time has passed than the condition X2. In other words, the condition X2 is less likely to be contaminated over time than the condition X3, and the amount of water discarded is reduced because simple cleaning is sufficient.

  When strong alkaline water or acidic water is taken and the time of 0 seconds or more and less than 30 seconds has elapsed after stopping the water (including the case where the mode is changed while passing water), or after stopping the water for 1 second or more during standby When the time of less than 30 minutes has elapsed, when taking alkali 1 to 3 water, a predetermined amount (0.3 L in the present embodiment) is discarded (hereinafter referred to as condition X4). This condition X4 is a state in which strong alkaline water or acidic water that is not suitable for drinking remaining in the electrode part 104 or in the piping is completely drained from the discharge port 19c, and alkali 1-3 water is discharged. Is to do. In other words, it is for replacing strongly alkaline water or acidic water that is not suitable for drinking remaining in the electrode part 104 or in the piping with alkali 1 to 3 water suitable for drinking.

  Further, in this wastewater amount definition table, the following definition is made to reduce wastewater as much as possible.

  In the case where water is taken again after 30 seconds or more and less than 30 minutes have elapsed after the water is stopped without waiting for reverse electricity, the water is not discarded regardless of the type of water taken last (hereinafter referred to as condition Y1). . That is, the alarm display control means, when water is taken again after the water stoppage, if the drainage in the electrolytic cell is completed by the staying drainage means and within a predetermined set time, the alarm by the drainage warning display means The display is not performed. This condition Y1 is not drained when there is no possibility that the water taken last will be mixed and there is no need to drain water when the water taken last in the electrode part 104 or in the piping does not remain. That's what it meant.

  When taking alkali 1 to 3 water or purified water again and taking alkali 1 to 3 water again, it is less than 30 minutes after water stoppage (regardless of whether or not it is waiting for reverse power) If it is included, the water is not discarded (hereinafter referred to as condition Y2). Although this condition Y2 is different in alkaline degree of alkali 1 water, alkali 2 water, and alkali 3 water, there is no difference that all are alkaline water suitable for drinking, and less than 30 minutes after water stoppage. If there is no possibility of contamination over time, it is decided not to drain the water in order to reduce it as much as possible.

  When water is taken and the time of 0 seconds or more and less than 30 seconds has elapsed since the water stopped (including when the water flow mode is changed), or during the reverse power standby time of 1 second or more and less than 30 minutes When the purified water is taken again, the water is not discarded (hereinafter referred to as condition Y3). As for this condition Y3, the water remaining in the electrode part 104 or in the pipe is purified water, and there is no problem even if it is mixed into the purified water to be taken again. Since there is no risk of contamination, water is not discarded to reduce wastewater as much as possible.

  When the time of 0 seconds or more and less than 30 seconds has elapsed after the water stoppage (including the case where the water has passed through, or when the mode has been changed) When strongly alkaline water or acidic water is taken, it is not discarded regardless of the type of water taken last (hereinafter referred to as condition Y4). In this condition Y4, when water that is not suitable for drinking is taken, compared to the case where water that is suitable for drinking is taken, there is less demand for highly accurate purity. In order to accept the contamination of water and to reduce the wastewater as much as possible, it is decided not to drain the water.

  Furthermore, as a characteristic point of this wastewater amount definition table, in order to be able to supply purified water to the user as soon as possible without draining even after taking electrolyzed water, it is defined as follows. ing.

  When strong alkaline water, alkaline 1 to 3 water, or acidic water is taken and the time of 0 seconds or more and less than 30 seconds has elapsed since the water was stopped (including when the mode is changed while water is running) When the time of 1 second or more and less than 30 minutes elapses after the water is stopped during standby, when purified water is taken, reverse liquid purified water is generated (hereinafter referred to as condition Z1). This condition Z1 can generate neutralized purified water by mixing electrolytic water and reverse liquid purified water present in the water discharge pipe in a container such as a cup when the user takes water.

  In addition, it is needless to say that the water discharge amount and the time condition in the water discharge amount definition table shown in FIG. 4 are examples, and can be appropriately changed according to the specifications of the water conditioner 1.

  As shown in FIG. 5, the electrolytic voltage value table is a table in which the type of water selected by the user is associated with the voltage value and application state applied to the water when generating the type of water. For example, in the case of generating alkaline 1 water, there is information such as applying an alkali voltage V2 [V] to the electrolysis unit 3.

  The reverse liquid water purification coefficient table determines the voltage to be applied to the water when generating the reverse liquid water, and is necessary for calculating the type of the electrolyzed water collected last and the reverse liquid water generation voltage value. There are information on the coefficient and added value, and the voltage application state. That is, the reverse liquid water purification coefficient table is a table for determining the voltage value of the reverse polarity voltage according to the strength of the liquidity of the electrolyzed water taken last.

  Specifically, the voltage applied to the water to generate the reverse liquid purified water is a value obtained by multiplying the voltage applied to generate the electrolyzed water discharged last by a coefficient and adding the added value.

  For example, when the electrolyzed water discharged last is alkaline 2 water, the voltage applied to the water to generate reverse liquid purified water corresponding to alkaline 2 water is V3 × 1.8 + 0 [V]. In addition, when the electrolyzed water discharged last is strong alkaline water, the voltage applied to the water to generate the reverse liquid purified water is V1 × 0 + 0.9 [V].

  In addition, the polarity of the voltage applied at that time is opposite to the voltage applied to generate the electrolyzed water discharged last, that is, alkaline 2 water is generated by applying alkali, so reverse liquid purified water is used. An acid is applied at the time of production, and acid water is produced by the application of an acid, so an alkali is applied at the time of production of reverse liquid purified water.

  In addition, according to the reverse liquid water purification coefficient table shown in FIG. 6, the voltage value required for the production of the reverse liquid water corresponding to the strong alkaline water is irrespective of the voltage value required when producing the strong alkaline water. It is set to a constant value (that is, 0.9 [V]), and other values are values that change in a linear function by multiplying by a coefficient, but are not limited thereto. It may be determined as appropriate.

  Moreover, in this embodiment, in order to determine the reverse liquid purified water generation voltage value, the value is a discrete table, but the type of the electrolyzed water taken last and the voltage for generating the reverse liquid purified water In addition, the correspondence between the type of electrolyzed water and the reverse liquid purified water generation voltage value may be continuous calculation information (for example, a correlation equation).

  Moreover, in this embodiment, in generating reverse liquid purified water, it was decided to use the reverse liquid purified coefficient table that uses the coefficient and the added value as information, but the present invention is not limited to this. For example, the voltage value Is fixed, and using the correlation information (calculation information) with the application time as information, the reverse liquid purified water is generated according to the strength of the electrolyzed water taken last by the length of the application time. good.

  Returning to the description of the electrical configuration of the water conditioner 1, the RAM 112 functions as a temporary storage area for storing various flags to be referred to when the CPU 110 executes a program stored in the ROM 111. Examples of the flags stored in the RAM 112 include a reverse electrolysis standby flag indicating whether or not reverse electrolysis is in standby, a drive signal flag indicating whether or not to output a drive signal, and an electrolysis relay. Electrolytic relay flag that indicates whether or not, electromagnetic valve opening flag that indicates whether or not to open the electromagnetic valve, drainage end flag that indicates whether or not draining has ended, whether or not in sleep mode A sleep mode flag indicating, a reverse liquid purified water generation end flag indicating whether or not the generation of the reverse purified water is completed, and a neutral purified water generation end flag indicating whether or not the generation of the neutralized purified water is completed. . In addition to these flags, for example, flags for storing inputs from the keys B1 to B10 are also stored. The actual handling of these flags in the program will be described later in detail using the flowcharts shown in FIGS.

  An RTC (Real Time Clock) denoted by reference numeral 115 is used to generate a clock pulse that serves as a reference for executing a system timer interrupt process described later. Even when the CPU 110 is executing the main process, the CPU 110 interrupts the main process according to a clock pulse generated every predetermined cycle (for example, 2 milliseconds) from the RTC 115, and performs a system timer interrupt process. May be executed. The RTC 115 also has a function of measuring the time elapsed since the last water intake and sequentially storing it in the RAM 112.

  The peripheral device interface 113 is responsible for operation control of peripheral devices connected to the control unit 7 and transmission / reception of signals. The peripheral device interface 113 includes the zero cross detection unit 102, the electrolytic relay 103, and the like. The electromagnetic valve 71, the flow sensor C, the display D, the keys B1 to B10, and the lamps L1 to L8 are connected to each other.

  The electromagnetic valve 71 is a valve that opens and closes based on an instruction from the CPU 110.

  The flow sensor C plays a role of detecting whether or not the purified water is flowing in the pipe and transmitting the amount of the purified water flowing to the control unit 7. The signal transmitted from the flow sensor C is stored in the predetermined address on the RAM 112 via the peripheral device interface 113 as the presence / absence of the flow rate and the accumulated water amount for each type of water taken.

  The display unit D plays a role of displaying information from the control unit 7 to the user. The display unit D is a water discharge warning for prompting water to be discarded for a predetermined time, a neutral water purification notification as a first notification indicating that neutral water purification is being generated, or generation of normal water purification. It functions as a notification unit that performs notification according to the properties of the discharged water, such as normal water purification notification as the second notification shown. Moreover, the control part 7 controls alerting | reporting to the display part D which is an alerting | reporting part, when the generation | occurrence | production signal of purified water is input by discharging the electrolyzed water by performing the below-mentioned flow.

  Each key B1 to B10 is a switch for realizing each function as described above. When the peripheral device interface 113 detects an input from each key B1 to B10, it sets a predetermined flag in the RAM 112. The CPU 110 can recognize which key is pressed. In particular, the input from the buttons B4 to B9 is a generation signal for purified water or electrolyzed water.

  Each of the lamps L1 to L8 is a lamp for displaying each state as described above, and is turned on or off through the peripheral device interface 113 based on an instruction from the CPU 110.

[Processing flow of control unit]
Next, the process in the control part 7 in the water adjuster 1 is demonstrated using FIGS. FIG. 7 is a flowchart showing the main process of the water conditioner 1 according to the present embodiment, FIG. 8 is a flowchart showing the operation of the system timer interrupt process, and FIGS. 9 to 11 and FIG. 7 is a flowchart showing the operation of the sub-process branched from the main process of FIG. 7, and FIG. 12 is a flowchart showing the operation of the sub-process branched from the purified water generation process of FIG.

  First, the main flow will be described with reference to FIG. First, the CPU 110 of the control unit 7 executes initial setting processing such as permitting access to the RAM 112 and initializing the work area (step S10).

  At this time, the CPU 110 sets the value of the reverse electrolysis standby flag in the RAM 112 to “0: reverse electrolysis non-standby”, the value of the drive signal flag to “0: drive signal stopped”, and the value of the electrolysis relay flag to “0: electrolysis”. “Relay operation stop”, electromagnetic valve open flag value “0: valve closed”, drainage end flag value “0: before drainage end”, sleep mode flag value “0: not in sleep mode”, The value of the reverse liquid purified water generation end flag is set to “0: reverse liquid purified water generation not completed”, and the value of the neutralized purified water generation end flag is set to “0: neutralized purified water generation not completed”. The flag value indicating the input of B10 is initialized.

  Next, the CPU 110 refers to the RAM 112 and determines whether or not there is water passing through the installation site of the flow sensor C (step S11).

  If it is determined that there is no water flow (step S11: No), the CPU 110 moves the process to step S12.

  In step S12, the CPU 110 refers to the RAM 112 and determines whether or not the value of the sleep mode flag is “1: in sleep mode”. Here, when it is determined that the value of the sleep mode flag is not “1” (step S12: No), the CPU 110 shifts the processing to step S13. On the other hand, when it is determined that the value of the sleep mode flag is “1” (step S12: Yes), the water conditioner 1 returns the process to step S11 again assuming that it is currently in the sleep mode, that is, in the standby state.

  In step S13, a reverse electrolysis confirmation process is performed to determine whether or not to perform a reverse electrolysis process for removing the scale adhering to the electrode by applying a voltage for a predetermined time while inverting the polarity of the electrode. . This reverse electrolysis confirmation process will be described later with reference to FIG.

  Thereafter, the CPU 110 executes a stoppage confirmation process (step S14). This confirmation process at the time of water stop is also demonstrated later using FIG. When the water stoppage confirmation process is completed, the CPU 110 returns the process to step S11 again.

  On the other hand, if it is determined in step S11 that there is water flow (step S11: Yes), the CPU 110 moves the process to step S15.

  In step S15, the CPU 110 refers to the RAM 112 and determines whether or not the water purification mode is set. If it is determined that the water purification mode is selected (step S15: Yes), the CPU 110 moves the process to step S16.

  In step S16, CPU110 performs a purified water production | generation process. This purified water generation process will be described later with reference to FIG. When this purified water generation process ends, the CPU 110 moves the process to step S11 again.

  On the other hand, when it is determined in step S15 that the water purification mode is not selected (step S15: No), the CPU 110 moves the process to step S17.

  In step S17, the CPU 110 refers to the RAM 112 and determines whether or not the electrolyzed water mode is set. If it is determined that the electrolyzed water mode is selected (step S17: Yes), the CPU 110 moves the process to step S18.

  In step S18, the CPU 110 executes an electrolyzed water generation process for generating acidic water or alkaline water. This electrolyzed water generation process will be described later with reference to FIG.

  On the other hand, if it is determined in step S17 that the mode is not the electrolyzed water mode (step S17: No), the CPU 110 moves the process to step S11 again.

  Next, the system timer interrupt process will be described with reference to FIG. That is, the CPU 110 may interrupt the main process and execute the system timer interrupt process even when the main process is being executed. The following system timer interrupt process is executed in response to a clock pulse generated every predetermined period (for example, 2 milliseconds) from the RTC 115.

  As shown in FIG. 8, first, when each key B1 to B10 is pressed, the CPU 110 executes each key press confirmation process referring to a flag set at a predetermined address in the RAM 112 by the peripheral device interface 113 (see FIG. 8). Step S20). That is, the CPU 110 executes step S20 so that it can be determined which key the user has pressed.

  Further, in each key pressing confirmation process, when it is confirmed that the user has pressed the strong alkaline water button B4, alkaline 1 button B5, alkaline 2 button B6, alkaline 3 button B7, water purification button B8, acidic water button B9, The CPU 110 sets the value of the drainage completion flag stored in the RAM 112 to “0: before drainage completion” and sets flags corresponding to the buttons B4 to B9. This flag serves as an index for determining what type of water the user has last drawn by referring to the CPU 110 in the processing described later. In addition, for example, when the alkali 2 button B6 is pressed, “Alkali 2” is displayed on the display unit D, and a display corresponding to the button selected on the display unit D is performed.

  Next, when the flow sensor C detects the flow of purified water, the CPU 110 executes a water flow confirmation process that refers to a flag set at a predetermined address in the RAM 112 by the peripheral device interface 113 (step S21). That is, the CPU 110 executes step S20 so that it can be determined whether or not clean water is flowing through the site where the flow sensor C is installed. In this step, when it is determined that the purified water is flowing through the installation site of the flow sensor C, the CPU 110 sets the value of the electromagnetic valve open flag stored in the RAM 112 to “1: valve open”. .

  Next, the CPU 110 refers to the drive signal flag in the RAM 112 and executes a zero cross drive signal output process for outputting or stopping the zero cross drive signal (step S22). In this zero-cross drive signal output process, when the value of the drive signal flag is “1: drive signal output”, a drive signal is output toward the zero-cross drive unit 121. When the value of the drive signal flag is “0: drive signal stop”, the drive signal is not output.

  Next, the CPU 110 performs a zero cross signal detection process (step S23) for detecting the zero cross signal output from the zero cross detection signal output unit 120.

  Next, the CPU 110 executes an electrolytic relay operation process (step S24). This electrolytic relay operation process energizes the electrode unit 104 when the value of the electrolytic relay flag is “1: electrolytic relay activated”, and receives the zero cross signal when it is received. When the signal voltage of the zero cross signal is at a high level and the value of the electrolytic relay flag is “1: electrolytic relay operation”, the electrode unit 104 is energized.

  Here, energization of the electrode unit 104 by the electrolytic relay 103 is performed by setting the electrolytic relay 103 at a polarity based on the timing stored in the ROM 111 in advance according to the selected mode and the application state of the electrolytic voltage value table. This is done by turning it on. Specifically, when the current mode is the acidic water mode, an acid is applied, and when the alkaline mode is 1 to 3 water, a voltage is applied to the electrode as compared with strongly alkaline water by pulse width control or the like Control time short.

  Next, CPU110 performs an electromagnetic valve operation process (step S25). In this electromagnetic valve operation process, when the signal voltage of the received zero cross signal is at a high level, the value of the electromagnetic valve open flag is “1: valve open”, and the electromagnetic valve is in a closed state, The CPU 110 instructs the peripheral device interface 113 to open the electromagnetic valve 71.

  Next, the CPU 110 executes sleep mode processing (step S26). In this sleep mode process, the value of the sleep mode flag stored in the RAM 112 is set to “1: on the condition that the user does not pass water or operates the keys B1 to B10, etc. for a predetermined time (for example, 1 hour). A process of setting the value of the sleep mode flag to “0: not in sleep mode” is performed when “sleep mode” is set, or when water is passed or each key B1 to B10 is operated. When this sleep mode process is completed, the process returns to the address before branching.

  Next, the reverse electrolysis confirmation process executed in step S13 of the main flow shown in FIG. 7 will be described with reference to FIG.

  As shown in FIG. 9, in the reverse electrolysis confirmation process, the CPU 110 first refers to the RAM 112, and the total sum of the generated alkaline water amounts of alkali 1, alkali 2, alkali 3, and strong alkaline water is a predetermined water amount (for example, 10L) is determined (step S30).

Here, if it is determined that the total does not exceed the predetermined amount of water, the CPU 110 moves the process to step S31.
In step S31, the CPU 110 sets the value of the reverse electrolysis standby flag stored in the RAM 112 to “0: reverse electrolysis non-standby”, and returns the process to the address before branching.

  On the other hand, if it is determined that the sum exceeds the predetermined amount of water (step S30: Yes), the process proceeds to step S32.

  In step S32, the CPU 110 sets the value of the reverse electrolysis standby flag stored in the RAM 112 to “1: reverse electrolysis standby”, and then determines whether or not a predetermined time (for example, 30 minutes) has elapsed since the water stoppage. That is, it is determined whether or not the water conditioner 1 has not been used for a while (step S33).

  More specifically, for example, in the water conditioner 1 installed in a general household or the like, a time zone in which the use time zone is relatively concentrated during the day, such as when cooking or washing the face, and other times When there is no use for a certain period of time (for example, 30 minutes) since the last use, it is determined that the time is relatively not used and disturbs water intake. The reverse electrolysis process described later is performed so as not to occur. The predetermined time is not particularly limited, and may be, for example, 10 minutes or 1 hour, or may be set appropriately by the user.

  If it is determined in step S33 that the predetermined time has not elapsed (step S33: No), the CPU 110 returns the processing to the address before branching.

  On the other hand, when determining in step S33 that the predetermined time has elapsed (step S33: Yes), the CPU 110 shifts the processing to step S34.

  In step S34, the CPU 110 sets the value of the drive signal flag stored in the RAM 112 to “1: drive signal output” and sets the value of the electrolysis relay flag to “1: electrolysis relay operation”. In this step S34, the value of the drive signal flag is set to “1: drive signal output”, so that the detection signal from the flow sensor C is not received (that is, in step S11 of the main process described above). Even when the reverse electrolysis process is performed, a drive signal is output to the zero cross drive unit 121 prior to the execution of the reverse electrolysis process.

  Next, the CPU 110 performs a reverse electrolysis process in which the electrodes of the electrolytic cell are energized in the reverse direction to clean the electrodes (step S35). In this reverse electrolysis treatment, a negative voltage is applied to the electrodes disposed in the first electrode chamber 32 and the third electrode chamber 44, while a positive voltage is applied to the electrodes disposed in the second electrode chamber 34 and the fourth electrode chamber 45. The scale attached to the electrode is removed by applying a voltage. In this embodiment, the execution time of the reverse electrolysis treatment (reverse voltage application time) is 10 seconds, but is not limited to this, and is appropriately adjusted according to the use environment, water quality, etc. of the water conditioner 1. You may make it do.

  After completing the reverse electrolysis process, the CPU 110 sets the value of the drive signal flag stored in the RAM 112 to “0: drive signal stop”, the value of the reverse electrolysis standby flag to “0: reverse electrolysis not standby”, and the electrolytic relay. The value of the flag is set to “0: electrolytic relay operation stop” (step S36), and the process is returned to the address before branching.

  Next, the water stoppage confirmation process executed in step S14 of the main flow shown in FIG. 7 will be described with reference to FIG.

  As shown in FIG. 10, in the water stoppage confirmation process, the CPU 110 first sets the value of the electrolysis relay flag stored in the RAM 112 to “0: electrolysis relay operation stop” and the value of the reverse liquid purified water generation end flag to “0”. : Reverse liquid purified water generation not completed ”and neutralized purified water production end flag are set to“ 0: Neutralized purified water generation not completed ”(step S40).

  Next, the CPU 110 determines whether or not the value of the reverse electrolysis standby flag is “1: reverse electrolysis standby” (step S41).

  If it is determined that the value of the reverse electrolysis standby flag is “1: reverse electrolysis standby” (step S41: Yes), the CPU 110 advances the process to step S43.

  On the other hand, when it is determined that the value of the reverse electrolysis standby flag is not “1: reverse electrolysis standby” (eg, “0: reverse electrolysis not standby”) (step S41: No), the CPU 110 performs processing. Move to S42.

  In step S42, the CPU 110 determines whether or not a predetermined time (for example, 30 seconds) has elapsed since the last water intake. During this predetermined time, the water stored in the first electrode chamber 32, the third electrode chamber 44, the second electrode chamber 34, and the fourth electrode chamber 45 of the electrolysis unit 3 is drained from the drain pipe 12a → the check valve 72 → the electromagnetic This is the time from the flow through the valve 71 to the discharge port 51 until it is completely removed. In the non-reverse electrolysis standby state, the electromagnetic valve 71 is closed after the water stored in the electrolysis unit 3 has been removed. Yes. In the present embodiment, the predetermined time in this step S42 is 30 seconds, but the time depends on the capacity of the first electrode chamber 32, the third electrode chamber 44, the second electrode chamber 34, the fourth electrode chamber 45, etc. May be changed.

  When it is determined in step S42 that a predetermined time has elapsed after water intake (step S42: Yes), the CPU 110 moves the process to step S43.

  On the other hand, if it is determined that the predetermined time has not elapsed since the intake (step S42: No), the process is returned to the address before branching. In addition, since the CPU 110 performs the processing in the flow of the above-described step S41: No → this step S42: No → RETURN, the electromagnetic valve is kept open even after the water stops, It plays the role of waste water treatment for draining the water in the electrolyzers 30 and 40.

  In step S43, the CPU 110 sets the value of the drive signal flag stored in the RAM 112 to “1: drive signal output”, and sets the value of the electromagnetic valve open flag to “0: valve closed”. By performing this step S43, it plays a role of a retention process for retaining water in the electrolytic cells 30 and 40. Moreover, CPU110 functions as a stay wastewater treatment means which can selectively perform a stay process and a wastewater process by performing the process of step S41-step S43.

  Next, the CPU 110 determines whether or not a predetermined time (for example, 1 second) sufficient for the operation of the electromagnetic valve 71 has elapsed (step S44).

  If it is determined that the predetermined time has not elapsed (step S44: No), the process is returned to the address before branching.

  On the other hand, if it is determined that the predetermined time has elapsed (step S44: Yes), the process proceeds to step S45.

  In step S45, the CPU 110 sets the value of the drive signal flag stored in the RAM to “0: stop drive signal”, and returns the process to the address before branching.

  Next, the purified water production | generation process performed by step S16 of the main flow shown in FIG. 7 is demonstrated using FIG.

  As shown in FIG. 11, in the purified water generation process, the CPU 110 first refers to the RAM 112 to confirm the type of the water taken last, the time elapsed since the last water intake, and the wastewater amount definition table stored in the ROM 111 and Collation is performed (step S50). At this time, the CPU 110 obtains information on whether the value of the specified wastewater amount or the generation of reverse liquid purified water is necessary from the wastewater amount definition table.

  Next, the CPU 110 determines whether or not draining is necessary (step S51). Here, when it is determined that water is not required (step S51: No), the process proceeds to step S56.

  In step S56, the CPU 110 determines whether or not it is necessary to generate reverse liquid purified water. Here, when it determines that the production | generation of reverse liquid purified water is required (step S56: Yes), a process is moved to step S57.

  In step S57, a reverse liquid purified water generation process is executed. This reverse liquid purified water generation process will be described later with reference to FIG. When this step S57 is completed, the CPU 110 returns the processing to the address before branching.

  On the other hand, if the CPU 110 determines in step S56 that the production of reverse liquid purified water is not necessary (step S56: No), the process returns to the address before branching. As can be seen by referring to the wastewater amount definition table shown in FIG. 4, if the drainage in the electrolyzers 30 and 40 is completed by the above-described staying drainage means and within a predetermined set time, The processing is returned to the address before branching as it is, and the warning display by the drain warning display processing (step S53) described later is not performed.

  In addition, if the type of water to be retaken is the same type of water as at the time of the previous take, if the elapsed time until retake is within the set time, no drainage is required. Regardless of whether the drainage is completed or not, no water discharge warning is displayed on the display unit D.

  If the CPU 110 determines in step S51 that drainage is necessary (step S51: Yes), the process proceeds to step S52.

  In step S52, the CPU 110 determines whether or not the value of the drainage end flag is “0: before the end of drainage”, and determines that the value of the drainage end flag is not “0” (step S52). : No), the process is returned to the address before branching. On the other hand, when it is determined that the value of the drainage end flag is “0” (step S52: Yes), the process proceeds to step S53.

  In step S53, the CPU 110 displays a water discharge warning on the display unit D. Here, the value or the like of the specified wastewater amount acquired from the wastewater amount definition table in step S50 is displayed, and the user is prompted to perform the water removal.

  Next, the CPU 110 refers to the RAM 112 and determines whether or not the purified water flowing through the flow rate sensor C has exceeded the specified water discharge amount, that is, whether or not the water discharge amount has been discharged from the discharge port 19c by the specified water discharge amount (step S54). ).

  Here, when it is determined that the specified amount of waste water has not been exceeded (step S54: No), the CPU 110 returns the processing to the address before branching. On the other hand, if it is determined that the specified amount of discarded water has been exceeded (step S54: Yes), the CPU 110 moves the process to step S55.

  In step S55, the CPU 110 ends the water discharge warning display and sets the value of the water discharge end flag stored in the RAM 112 to “1: water discharge end”. Then, the CPU 110 returns the processing to the address before branching.

  Next, the reverse liquid purified water generation process executed in step S56 of the purified water generation process shown in FIG. 11 will be described with reference to FIG.

  As shown in FIG. 12, in the reverse liquid purified water generation process, the CPU 110 refers to a predetermined address in the RAM 112 and determines whether or not the value of the neutralized purified water generation end flag is “1: neutralized purified water generation end”. A determination is made (step S80).

  If the CPU 110 determines that the value of the neutralized purified water generation end flag is “1: neutralized purified water generation complete” (step S80: Yes), the process returns to the address before branching.

  On the other hand, when the CPU 110 determines that the value of the neutralized purified water generation end flag is not “1: neutralized purified water generation end” (step S80: No), the process proceeds to step S81.

  In step S <b> 81, the CPU 110 determines whether or not the value of the reverse liquid purified water generation end flag is “1: reverse liquid purified water generation end”.

  Here, when it is determined that the value of the reverse liquid purified water generation end flag is “1: reverse liquid purified water generation end” (step S81: Yes), the CPU 110 shifts the process to step S84.

  On the other hand, when it is determined that the value of the reverse liquid purified water generation end flag is not “1: reverse liquid purified water generation end” (step S81: No), the CPU 110 moves the process to step S82.

  In step S82, the CPU 110 refers to the reverse liquid purified water coefficient table stored in the ROM 111, and acquires the reverse liquid purified water generation voltage value and polarity according to the type of the water taken last. And CPU110 calculates a reverse liquid purified water production | generation voltage value based on the coefficient acquired from the reverse liquid purified water coefficient table, and an addition value (step S82).

  Next, in step S83, the CPU 110 sets the application state acquired from the reverse liquid purification coefficient table to the electrolysis relay 103, and sets the value of the electrolysis relay flag to “1: electrolysis relay operation”.

  And CPU110 displays on the display part D that it is producing | generating neutralized water (step S84), and moves a process to step S85.

  In step S85, the CPU 110 determines whether or not the amount of water that has flowed through the flow sensor C is less than 100 ml up to the specified water amount (300 ml in the present embodiment).

  Here, when it is determined that the specified water amount is less than 100 ml (step S85: Yes), the CPU 110 moves the process to step S86.

  In step S86, the CPU 110 sets the value of the reverse liquid clean water generation end flag to “1: reverse liquid clean water generation end”, and sets the value of the electrolysis relay flag to “0: electrolysis relay operation stop”, processing. To step S87.

  On the other hand, when it is determined in step S85 that the specified water amount is not less than 100 ml (step S85: No), the CPU 110 moves the process to step S87.

  In step S87, the CPU 110 determines whether or not the amount of water that has flowed through the flow sensor C has exceeded a specified amount of water.

  Here, when it is determined that the specified amount of water has been exceeded (step S87: Yes), the CPU 110 moves the process to step S88.

  In step S88, the CPU 110 sets the value of the neutralized purified water generation end flag to “1: neutralized purified water generation end” and displays on the display unit D that normal purified water is being generated. When step S88 is completed, the CPU 110 returns the process to the address before branching.

  On the other hand, when it is determined in step S87 that the specified water volume has not been exceeded (step S87: No), the CPU 110 returns the process to the address before branching.

  Next, the electrolyzed water generation process executed in step S18 of the main flow shown in FIG. 7 will be described with reference to FIG.

  As shown in FIG. 13, in the electrolyzed water generation process, the CPU 110 first refers to the RAM 112 to confirm the type of water selected by the user, the type of water taken last, and the time elapsed since the last water intake. Then, it is collated with the wastewater amount definition table stored in the ROM 111 (step S60). At this time, the CPU 110 acquires the value of the specified water discharge amount from the water discharge amount definition table.

  Next, the CPU 110 determines whether or not drainage is necessary (step S61). If it is determined that drainage is not necessary (step S61: No), the electrolysis according to the type of the selected water is performed. The voltage value is acquired from the electrolytic voltage value table, the value of the drive signal flag stored in the RAM 112 is set to “1: drive signal output”, and the value of the electrolysis relay flag is set to “1: electrolysis relay operation” ( In step S62), the process returns to the address before branching.

  On the other hand, when it is determined that water is required (step S61: Yes), the process proceeds to step S63.

  In step S63, the CPU 110 acquires the electrolytic voltage value corresponding to the selected water type from the electrolytic voltage value table, and sets the value of the electrolytic relay flag to “1: electrolytic relay operation”. Then, the CPU 110 determines whether or not the value of the drainage completion flag is “1: drainage completion” (step S64). Here, when the value of the drainage completion flag is “1” (step S64: Yes), the CPU 110 returns the processing to the address before branching. On the other hand, when it is determined that the value of the water removal completion flag is not “1” (step S64: No), the CPU 110 moves the process to step S65.

  In step S65, the CPU 110 displays a water discharge warning. Here, the value or the like of the specified wastewater amount obtained from the wastewater amount definition table in step S60 is displayed, and the user is prompted to perform the water removal.

  Next, the CPU 110 refers to the RAM 112 and determines whether or not the amount of purified water flowing through the flow sensor C is less than 100 ml up to the zero cross start water amount (step S66).

  Here, when it is determined that the remaining water amount is not less than 100 ml until the zero cross start water amount (step S66: No), the CPU 110 shifts the process to step S68. On the other hand, if it is determined that the remaining water amount is less than 100 ml until the zero cross start water amount (step S66: Yes), the CPU 110 moves the process to step S67.

  In step S67, the CPU 110 sets the value of the drive signal flag stored in the RAM 112 to “1: drive signal output”, and moves the process to step S68. Note that, by setting the value of the drive signal flag to “1: drive signal output” in step S67 or step S62 described above, the zero-cross drive unit 121 is received when the detection signal from the flow sensor C is received. A drive signal is output to Further, the CPU 110 outputs the display signal to the water discharge warning display means (display unit D) by executing the above-described step S65, step S66, and the present step S67, and then outputs the drive signal to the zero-cross drive unit 121. It will be.

  In step S68, the CPU 110 refers to the RAM 112 and determines whether or not the purified water flowing through the flow rate sensor C has exceeded the specified water discharge amount, that is, whether or not the discharge water 19c has been discharged by the specified water discharge amount.

  Here, if it is determined that the specified amount of water has not been exceeded (step S68: No), the CPU 110 returns the processing to the address before branching. On the other hand, if it is determined that the specified amount of discarded water has been exceeded (step S68: Yes), the CPU 110 moves the process to step S69.

  In step S69, the CPU 110 ends the water discharge warning display and sets the value of the water discharge end flag stored in the RAM 112 to “1: water discharge end”. Then, the CPU 110 returns the processing to the address before branching.

  As described above, such a process is performed in the water adjuster 1 according to the present embodiment.

  Next, the actual movement of the water conditioner 1 having the above-described configuration will be described with reference to FIG. FIG. 14 shows the switch operation of the water conditioner 1 according to the present embodiment, the state display on the display unit D, the detection of purified water in the flow sensor C, the water discharge warning display on the display unit D, the water purification type display on the display unit D, It is explanatory drawing which showed the timing of the drainage from the electrode part after electrolysis, the output of a zero cross drive signal, solenoid valve operation | movement, and water intake. Further, FIG. 14A shows a state in which the reverse electrolysis is in a standby state, that is, the total amount of water that has generated strong alkaline water, alkali 1 water, alkali 2 water, and alkali 3 water after the last reverse electrolysis treatment is a predetermined amount of water. FIG. 14 (b) shows the operation of the water conditioner 1 that is in a standby state for performing the reverse electrolysis treatment when it exceeds the time zone (for example, 10L) and is in a relatively unused time period as described above. Shows the operation of the water conditioner 1 in a state in which the reverse electrolysis is not on standby, that is, in a state where the total amount of water that has generated each of the alkaline water is less than a predetermined amount.

  Describing in chronological order based on FIG. 14, first, when the user presses, for example, the alkali 3 button B <b> 7, the display unit D displays that the alkali 3 water has been selected.

  Next, when the user opens the water tap 11a (see FIG. 1) and supplies raw water to the water conditioner 1, the flow sensor C detects the flow of purified water, and as shown in FIG. 16 (a), A water drain warning is displayed on the information notification unit 85 of the display unit D, and electrolysis is started. On the display unit D, a status display unit 86, an information notification unit 85, and a cartridge replacement information display unit 87 are provided, and the type of water selected by the user is displayed on the status display unit 86. Then, the water discharge warning display, the neutralized purified water generation display, and the normal purified water generation display are displayed on the information notification unit 85 and notified. The cartridge replacement information display unit 87 is a display for prompting the user to replace the upper cartridge 20a and the lower cartridge 20b based on the information from the flow sensor C.

  Also, the zero cross drive signal is output almost simultaneously, the solenoid valve is opened at the zero cross timing, and the output of the zero cross drive signal is stopped soon.

  Next, when the control unit 7 determines that the amount of purified water flowing through the flow sensor C has exceeded the zero-crossing start water amount, the zero-cross drive signal is output again, and thereafter, when the control unit 7 determines that the specified wastewater amount has been exceeded, Disappear.

  Thereafter, when the water intake by the user is finished and the water tap 11a is closed, the flow sensor C detects water stoppage, the electrolysis is stopped, and the electromagnetic valve is closed.

  Thereafter, when water is not taken in by the user and a certain time (for example, 30 minutes) has elapsed, the control unit 7 outputs a zero-cross drive signal, and performs reverse electrolysis for a predetermined time (for example, 10 seconds) at the zero-cross timing.

  When the reverse electrolysis is completed, the electromagnetic valve 71 is opened at the zero cross timing, and the output of the zero cross drive signal is stopped.

  Then, after the time for sufficient drainage has elapsed, the zero cross drive signal is output again, the electromagnetic valve 71 is closed, and then the output of the zero cross drive signal is stopped, and the display unit D shifts to the sleep mode. Turns off the display.

  After such water intake, when the user again takes water in the order of alkaline 3 water → acidic water → alkaline 3 water → alkaline 3 water → purified water → alkaline 3 water, FIG. 14 (a) It will operate as shown in the subsequent stage.

  That is, for example, when the alkali 3 button B7 is pressed by the user, the display unit D displays that the alkali 3 water has been selected.

  Next, when the user opens the water tap 11a and supplies raw water to the water conditioner 1, the flow sensor C detects the flow of purified water and displays a drainage warning on the display unit D in accordance with the condition X1. Then, electrolysis is started.

  Further, when the acidic water is taken soon after taking the alkaline 3 water (for example, 30 seconds or more and less than 30 minutes), the condition Y4 is met, and the water discharge warning is not displayed. Thereby, the amount of waste water can be reduced as much as possible.

  Thereafter, when the intake of acidic water is finished and the alkali 3 button B7 is pushed down and the water is passed through the water conditioner 1, a water drain warning is displayed in accordance with the condition X4 to prompt the user to drain the water.

  In addition, if the same alkaline 3 water is taken soon after the intake of the alkaline 3 water, the condition Y2 is satisfied and the water discharge warning is not displayed, and the amount of water discharged is reduced as much as possible. That is, if the type of water to be retaken is the same type of water as at the time of the previous intake, if the elapsed time up to the retake is within the set time, how is the drainage in the electrolytic cell completed? Regardless, the warning display by the water discharge warning display means is not performed.

  After that, when the intake of the alkaline 3 water is finished and the water purification button B8 is pressed soon and the water is passed through the water conditioner 1, the condition Z1 is met.

  At this time, neutralized water purification display is performed on the display unit D, and reverse liquid water is generated by applying a reverse liquid water generation voltage to the electrolysis unit 3. That is, it does not prompt the user to discard water. In addition, this neutralization water purification display and the production | generation of reverse liquid purification water are explained in full detail behind.

  Next, the generation of the reverse liquid purified water stops, and the purified water is supplied to the electrolysis unit 3 to which no voltage is applied, and the normal purified water display is performed on the display unit D with a slight delay.

  Then, after finishing the water intake, when the alkali 3 button B7 is pressed and the water is passed through the water conditioner 1, the water discharge warning is displayed in accordance with the condition Y2, and the amount of water discharged is reduced as much as possible. Yes.

  As described above, when the water conditioner 1 is in reverse electrolysis standby, it operates in this way.

  Here, generation of purified water characteristic of the present embodiment, particularly generation of neutralized purified water and display timing thereof will be described with reference to FIGS. 15 and 16.

  FIG. 15 is an explanatory view showing the generation of neutralized water, the display timing, and the like in the generation process Q shown in FIG. Specifically, FIG. 15A shows the display timing in the display unit D, FIG. 15B shows the voltage value and polarity applied to the electrolysis unit 3, and FIG. The pH of the water discharged from the discharge port 19c is shown, FIG.15 (d) has shown the change of the cumulative pH of the neutralized purified water discharged during the neutralized purified water display. FIG. 16 is an explanatory diagram showing the display state of the display unit D.

  During the generation of the alkaline 3 water, a display indicating that the alkaline 3 water is being generated is displayed on the state display unit 86 as shown in FIGS. 15 (a) and 16 (b).

  At this time, as shown in FIG. 15B, a voltage is applied to the electrolysis unit 3 at a voltage value V4 in the case of generating alkali 3 water obtained from the electrolysis voltage value table (see FIG. 5). As shown in FIG. 15C, alkaline alkaline 3 water is discharged from the discharge port 19c.

  And if a user finishes water intake of alkaline 3 water, passes the interruption period L, and presses water purification button B8 in order to obtain purified water, as shown in FIG.15 (b), it will be in the state display part 86 of the display part D. Is displayed that the purified water is being generated, and the information notification unit 85 is displayed that the neutralized purified water is being generated, and is notified to the user.

  At this time, according to the reverse liquid water purification coefficient table (see FIG. 6), the electrolysis unit 3 is multiplied by the coefficient applied to generate the electrolyzed water discharged last, and is added to the voltage value. The voltage having the opposite polarity to the voltage applied to generate the electrolyzed water discharged last, that is, according to this embodiment, a voltage of −V4 × 1.8 [V] is applied with alkali (V4). A voltage of x1.8 [V] is applied with an acid).

  Then, as shown in FIG. 15 (c), about 100 ml of alkali 3 water stored in the water discharge pipe is first discharged from the discharge port 19c, and subsequently, acid reverse liquid purified water is discharged. The

  The application of the reverse liquid purified water generation voltage is applied for generating 200 ml of reverse liquid purified water, which is twice the capacity of the water discharge pipe (100 ml in the present embodiment), and then is turned off.

  Then, when the neutralized purified water generation is displayed and 300 ml of water is discharged, a display indicating that normal purified water is being generated is performed as shown in FIG.

  Here, when looking at the accumulated pH of the water discharged while the neutralized water purification display is being made, as shown in FIG. 15 (d), the liquidity that was initially inclined to the alkaline side due to the discharge of alkaline 3 water was found. Then, the pH gradually decreases due to the mixing of the reverse liquid purified water, becomes neutral when 300 ml is discharged (when the neutralized purified water display disappears), and 300 ml of neutralized purified water is produced.

  That is, immediately after the user presses the water purification button, water is collected while being stored in a container such as a cup, so that neutralized purified water is removed when it exceeds 300 ml (when the capacity exceeds 3 times the water discharge line). Even after the electrolyzed water is taken, the user can be provided with purified water as quickly as possible without discarding it.

  In addition, the display period of the neutralized water purification display is the time from the start of water discharge to the time when three times the water discharge pipe volume is discharged, and the electrolysis for generating reverse liquid purified water is the start of water discharge. It is set as time to discharge water twice the water discharge pipe volume.

  In other words, the neutralized water purification display period is divided into 2: 1, the first two-thirds are used for the production of reverse liquid clean water, and the second third is used for normal water purification, which pushes out the reverse liquid clean water in the water discharge line. I'm on time.

  This period allocation of 2: 1 is the optimum ratio obtained by the present inventors' experience and earnest research, but can be changed according to the specifications of the water conditioner 1 or the like. For example, while the user discharges about 200 to 400 cc (that is, about one cup) immediately after pressing the water purification button B8, the accumulated pH of the discharged water is controlled to be in a neutral region. good.

  In addition, in order to discharge reverse liquid purified water during neutralized purified water display, it is sufficient that at least the cumulative flow rate during neutralized purified water display is set to be larger than the water discharge pipe volume, and the final concentration referred to in the present invention is The pH concentration of water (about 200 cc) that is in the user's cup at the end of the neutralized water purification display may be controlled so that the pH is in a neutral region.

  Returning to the description of FIG. 14 again, even in the case of the water conditioner 1 in the state of not waiting for reverse electrolysis, as shown in the previous stage of FIG. 14 (b), when the user presses the alkali 3 button B7, The operation is the same as during the reverse electrolysis standby, but when the water intake is completed, the zero-cross drive signal is immediately stopped and the electromagnetic valve 71 is kept open for a certain time (for example, 5 minutes).

  When the predetermined time elapses, the controller 7 outputs the zero cross drive signal again, closes the electromagnetic valve 71 at the zero cross timing, and stops the output of the zero cross drive signal.

  By operating in this way, the stored water in the electrolysis unit 3 can be drained reliably, and then the electromagnetic valve is closed to shut off the electrolysis unit 3 and the outside and clean the electrolysis unit 3. In addition, the closing operation can be performed at the timing of zero crossing.

  Similarly, at 30 minutes or more and less than 8 hours after stopping the water, the user intermittently takes water in the order of alkaline 3 water → acidic water → alkaline 3 water, then alkaline 3 water → acidic water → alkaline 3 water → When water is continuously taken in the order of purified water → alkaline 3 water, the operation is as shown in the subsequent stage of FIG.

  That is, for example, when the alkali 3 button B7 is pressed by the user, the display unit D displays that the alkali 3 water has been selected.

  Next, when the user opens the water tap 11a and supplies raw water to the water conditioner 1, the flow sensor C detects the flow of purified water and displays a drain warning on the display unit D in accordance with the condition X2. Then, electrolysis is started.

  In addition, after taking 3 alkaline waters and stopping water (for example, 30 seconds or more and less than 30 minutes), when acid water is taken, the above-mentioned condition Y4 is satisfied, and no water discharge warning is displayed. . Thereby, the amount of waste water can be reduced as much as possible.

  In addition, unlike in the state of waiting for reverse electrolysis, when acid water is taken in and water is stopped immediately (for example, 30 seconds or more and less than 30 minutes), when alkaline 3 water is taken, drain immediately after taking the previous acidic water. Is carried out and acidic water is not stored in the electrolysis unit 3, the condition Y1 is met, and no water discharge warning is displayed. Thereby, the amount of waste water can be reduced as much as possible.

  In addition, when the subsequent alkali 3 water → acidic water is taken continuously, that is, when the mode is switched to a mode in which water suitable for drinking is taken and water that is not suitable for drinking is generated while maintaining the water flow state. In this case, the condition Y4 is satisfied, and the display of the waste water is not performed. This also reduces the amount of the waste water as much as possible.

  In addition, when the subsequent acidic water → alkaline 3 water is taken continuously, that is, when the mode is switched to a mode in which water that is not suitable for drinking is taken and water that is suitable for drinking is generated while maintaining the water flow state. In this case, the condition X4 is satisfied, and a drain warning is displayed to prompt the user to drain the water.

  Thereafter, when water is continuously taken from alkaline 3 water to purified water, the condition Z1 is satisfied.

  At this time, the neutralization water purification display is performed on the display unit D, and the reverse liquid water purification is generated by applying the reverse liquid water generation voltage to the electrolysis unit 3, as in the case of waiting for the reverse power. Subsequently, normal water purification display is performed on the display part D, and normal water purification is generated. That is, it does not prompt the user to discard water. In addition, the neutralization water purification display in this non-back-charging non-standby state and the production | generation of reverse liquid purification water are explained in full detail behind.

  After that, when water is continuously taken from purified water to alkaline 3 water, the condition Y2 is met and the water discharge indication is not performed, so that the amount of water discharge can be reduced as much as possible. ing.

  Here, the neutralization water purification display in the above-mentioned reverse electricity non-standby state and the production | generation of reverse liquid purification water are demonstrated using FIG. In addition, although description here has a part which overlaps partially with the description at the time of the reverse power standby state demonstrated using FIG. 15, in order to make an understanding easy, it may explain again. FIG. 17 is an explanatory diagram showing the generation of neutralized water, the display timing, and the like in the generation process R shown in FIG.

  During the generation of the alkaline 3 water, a display indicating that the alkaline 3 water is being generated is displayed on the state display unit 86 as shown in FIGS. 17 (a) and 16 (b).

  At this time, as shown in FIG. 17B, a voltage is applied to the electrolysis unit 3 at a voltage value V4 in the case of generating alkali 3 water obtained from the electrolysis voltage value table (see FIG. 5). As shown in FIG. 17C, alkaline alkaline 3 water is discharged from the discharge port 19c.

  Then, when the user presses the water purification button B8 during alkaline 3 water discharge, as shown in FIG. 17 (a), the state display unit 86 of the display unit D displays that purified water is being generated. At the same time, the information notification unit 85 displays that neutralized purified water is being generated, and notifies the user.

  At this time, as shown in FIG. 17 (b), the electrolysis unit 3 has a coefficient applied to the voltage applied to generate the discharged electrolyzed water according to the reverse liquid water purification coefficient table (see FIG. 6). A voltage obtained by multiplying and adding the added value and having a polarity opposite to the voltage applied to generate the electrolyzed water discharged last, that is, according to this embodiment, −V4 × 1.8. A voltage of [V] is applied with an alkali (a voltage of V4 × 1.8 [V] is applied with an acid).

  Then, as shown in FIG. 17 (c), about 100 ml of alkali 3 water stored in the water discharge pipe is first discharged from the discharge port 19c, and subsequently acid reverse liquid purified water is discharged. The

  The application of the reverse liquid purified water generation voltage is applied for generating 200 ml of reverse liquid purified water, which is twice the capacity of the water discharge pipe (100 ml in the present embodiment), and then is turned off.

  Then, when the neutralized purified water generation is displayed and 300 ml of water is discharged, a display indicating that normal purified water is being generated is performed as shown in FIG.

  Here, when looking at the accumulated pH of the water discharged while the neutralized water purification display is being made, as shown in FIG. Then, the pH gradually decreases due to the mixing of the reverse liquid purified water, becomes neutral when 300 ml is discharged (when the neutralized purified water display disappears), and 300 ml of neutralized purified water is produced.

  That is, immediately after the user presses the water purification button, water is collected while being stored in a container such as a cup, so that neutralized purified water is removed when it exceeds 300 ml (when the capacity exceeds 3 times the water discharge line). Even after the electrolyzed water is taken, the user can be provided with purified water as quickly as possible without discarding it.

  Thereafter, when the user presses the alkali 3 button B7 again during clean water discharge, as shown in FIG. 17, a display indicating that alkali 3 water is being generated is displayed on the state display portion 86 of the display portion D. At the same time, the voltage V4 is applied to the electrolysis unit 3 with alkali, and alkali 3 water is discharged from the discharge port 19c.

[Other embodiment 1]
In the water conditioner 1 which concerns on above-mentioned embodiment, as shown in FIG.16 (b), the 1st alert | report showing that neutralized purified water is being produced | generated is made into neutralized purified water alert | report, and it is the production | generation of normal purified water. Although the 2nd alerting | reporting which shows this was made into normal water purification alert | reporting, if the boundary of the production | generation of neutralization purified water and production | generation of normal water purification can be alert | reported with respect to a user, it will not specifically limit to this.

  Then, in other Embodiment 1, the water conditioner which changed the alerting | reporting form of 1st alerting | reporting and 2nd alerting | reporting is demonstrated. In addition, in the following description, since it has the structure similar to the above-mentioned water adjuster 1 except the above-mentioned difference, description is abbreviate | omitted.

  The water conditioner 200 according to the other embodiment 1 is different in configuration in that the first notification and the second notification are displayed as a water discharge recommendation display and a drinking display as shown in FIG.

  Here, the water discharge recommendation display is a display for recommending water to the user, and the appeal of water discharge is slightly weaker than the water discharge warning display.

  By adopting such a configuration, it is possible to notify the user of the timing when normal clean water is generated as “drinking time” and to a container such as a cup during a water discharge warning display due to various circumstances of the user. Even when water is taken, purified water (neutralized purified water) can be provided at an early stage.

  In addition, in this other Embodiment 1, although the 2nd display was set as the drinking time display, of course, it is good also considering the 2nd display as the normal water purification display shown in FIG.16 (b).

[Other embodiment 2]
In the water conditioner 1,200 according to the above-described embodiment and the other embodiment 1, as shown in FIG. 15 and FIG. 17, the neutralized water purification display period is divided into 2: 1, and the first half of the first half is In the production of the reverse liquid purified water, the latter half of the latter half is usually used for the time to push out the reverse liquid purified water in the water discharge pipe with the normal purified water, but it is not particularly limited to this.

  Then, other Embodiment 2 demonstrates the water adjuster 300 which changed the production | generation timing of reverse liquid purified water. In addition, in the following description, since it has the structure similar to the above-mentioned water adjuster 1 and the water adjuster 200 except the above-mentioned difference, description is abbreviate | omitted. In order to simplify the explanation, the operation in the generation process R for continuous water discharge shown in FIG. 14B will be described, and the operation in the generation process Q for intermittent water discharge will be described. Omitted.

  At the time of purified water generation in the generation process R shown in FIG. 14B, in the water conditioner 300 according to the other embodiment 2, as shown in FIG. When the water purification button B8 is pressed, the state display unit 86 of the display unit D displays that purified water is being generated, and the information notification unit 85 displays that neutralized purified water is being generated, Informed to the user.

  At this time, as shown in FIG. 19B, the electrolysis unit 3 has a coefficient applied to the voltage applied to generate the discharged electrolyzed water according to the reverse liquid water purification coefficient table (see FIG. 6). A voltage obtained by multiplying and adding the added value and having a polarity opposite to the voltage applied to generate the electrolyzed water discharged last, that is, according to this embodiment, −V4 × 1.8. A voltage of [V] is applied with an alkali (a voltage of V4 × 1.8 [V] is applied with an acid).

  Then, as shown in FIG. 19 (c), about 100 ml of alkali 3 water stored in the water discharge pipe is first discharged from the discharge port 19c, and subsequently, acid reverse liquid purified water is discharged. The

  Here, the application of the reverse liquid purified water generation voltage in the second embodiment is stopped when the accumulated pH of the discharged water shown in FIG. 19 (d) becomes neutral (pH 7) (FIG. 19 ( b)), and the neutral water purification display that is the first notification is switched to the normal water purification display that is the second notification (see FIG. 19A).

  Even by performing such control, immediately after the user presses the water purification button, water is collected while being stored in a container such as a cup, so that the time when it exceeds 300 ml (three times the capacity of the water discharge conduit). Neutralized purified water can be obtained at the time of exceeding), and the purified water can be provided to the user as soon as possible without draining even after taking the electrolyzed water.

  In addition, as shown in FIG.19 (c), even after neutralization water purification display disappears, reverse liquid water will be discharged a little, and as shown with a broken line in FIG.19 (d), accumulated pH is pH7. However, since it is within the neutral range, it can be said that it is normal purified water even when it is taken immediately after the neutralized purified water display end (that is, immediately after the normal water purification display is made).

[Other embodiment 3]
In the water conditioners 1, 200 and 300 according to the above-described embodiment and other embodiments 1 and 2, as shown in FIG. 16 and FIG. However, the present invention is not limited to this.

  Therefore, in another embodiment 3, a water conditioner 400 that performs the first notification and the second notification by another means will be described. In addition, in the following description, description is abbreviate | omitted about the structure similar to the above-mentioned water adjuster 1, the water adjuster 200, and the water adjuster 300. FIG.

  FIG. 20 is an explanatory diagram showing the operation panel P of the water adjuster 400 according to the third embodiment. As shown in FIG. 2, the configuration of the operation panel P is almost the same as that of the above-described water regulator 1,200,300, but the power button B1, the strong alkaline water button B4, the alkaline water buttons B5 to B7, and the purified water. The button B8 and the acid water button B9 are each provided with a light emitting unit 90, and a water discharge warning lamp L9 is provided. The display unit D performs a water discharge warning display, a first notification, and a second notification. The configuration is different in that it is not broken.

  The light emitting unit 90 provided in each button is lit when each button is pressed by the user. In the power button B1, the power-on state is indicated in each button B3 to B9. Thus, the user can be notified of the type of water selected.

  Moreover, the water discharge warning lamp L9 substitutes the water discharge warning display which was displayed on the display part D by the above-mentioned water conditioner 1,200,300, and makes this water discharge warning lamp L9 light. Thus, the user is made to recognize the water discharge warning. In addition, in FIG. 20, the state which the power button B1, the water purification button B8, and the water discharge warning lamp L9 is lighting is shown.

  In the water conditioner 400 having such a configuration, the other embodiment 3 is characterized by the combination of the lighting state and the lighting time of the light emitting unit 90 of the water purification button B8 and the water discharge warning lamp L9. The first notification and the second notification are made to the person.

  A specific operation will be described with reference to FIG. 17. First, as shown in FIG. 17A, the light emitting portion 90 of the alkali 3 button B7 is lit while the alkali 3 water is being discharged.

  Next, when the user depresses the water purification button B8 while discharging the alkaline 3 water, the light emitting unit 90 of the alkaline 3 button B7 is turned off, the light emitting unit 90 of the water purification button B8 is turned on, and the water discharge warning lamp L9 is turned on. Turns on and asks the user to recognize that neutralized purified water is being generated, which is the first notification.

  At this time, as shown in FIG. 17B, the electrolytic unit 3 is subjected to an alkali application of a voltage of −V4 × 1.8 [V] (a voltage of V4 × 1.8 [V] is applied with an acid), As shown in FIG. 17 (c), about 100 ml of alkali 3 water stored in the water discharge pipe is first discharged from the discharge port 19c, and then acid reverse liquid purified water is discharged.

  The application of the reverse liquid purified water generation voltage is applied for generating 200 ml of the reverse liquid purified water, which is twice the capacity of the water discharge pipe (100 ml in the other embodiment 3), and then is turned off.

  And when neutralization water purification production | generation is made | formed and 300 ml of water is discharged, the water discharge warning lamp L9 will go out and the 2nd alert | report which shows that it is producing | generating normal water purification will be performed with respect to a user.

  Then, when the alkali 3 button B7 is pressed by the user during clean water discharge, the light emitting unit 90 of the water purification button B8 is turned off, and the light emitting unit 90 of the alkali 3 button B7 is turned on, so 3 Informs that water is generated.

  As described above, even the water conditioner 400 having such a configuration can perform the first notification and the second notification.

  In addition, as a state where the light emitting unit 90 of the water purification button B8 and the water discharge warning lamp L9 are lit at the same time (hereinafter simply referred to as “simultaneous lighting state”), in addition to the case of the first notification described above. A case where the condition X3 is satisfied is conceivable.

  When the condition X3 is met and the light is on at the same time, the water is being discharged while washing the inside of the electrode part 104 and the inside of the pipe, and it is not preferable to drink this. However, as can be seen from the wastewater amount definition table shown in FIG. 4, the wastewater amount is set to 1 L which is sufficiently larger than the amount of neutralized purified water produced (300 ml), and is in the simultaneous lighting state in accordance with the condition X3. In this case, even when the user takes water into a container such as a cup, it is clearly longer than the lighting time of the simultaneous lighting state at the time of neutralized purified water generation.

  Therefore, the user can be made to recognize whether the simultaneous lighting state is in the generation of neutralized purified water or the state that matches the condition X3.

  As described above, according to the water conditioner 1,200,300 according to the present embodiment, the control unit performs notification by the notification unit when a generation signal of purified water is input during or after discharge of the electrolyzed water. In addition, the voltage having the opposite polarity to the voltage applied to generate the electrolyzed water discharged last is applied to the electrode. Even if it is not immediately after, the purified water can be supplied as soon as possible without draining even after taking the electrolyzed water.

  Finally, the description of each embodiment described above is an example of the present invention, and the present invention is not limited to the above-described embodiment. For this reason, it is a matter of course that various modifications can be made in accordance with the design and the like as long as they do not depart from the technical idea according to the present invention other than the embodiments described above.

  For example, in each of the above-described embodiments, the case where purified water is generated from the alkali 3 when the condition Z1 is met has been mainly described. However, when purified water is generated from other alkaline water, purified water is generated from acidic water. In this case, it is needless to say that the purified water can be supplied to the user as soon as possible by generating the neutralized purified water. In addition, when producing | generating reverse liquid purified water at the time of producing | generating purified water from acidic water, as shown also in the reverse liquid purified water coefficient table of FIG. 6, the application state to the electrolysis part 3 becomes an alkali application.

  Moreover, in each said embodiment, although it decided to display by displaying a drain warning, 1st alerting | reporting, and 2nd alerting | reporting on the display part D, for example, a buzzer sound, a music, an audio | voice, etc. May be notified either alone or in combination.

  Moreover, in each said embodiment, although the capacity | capacitance of the water discharge pipe line was 100 ml, a different capacity | capacitance may be sufficient. At this time, the neutralized water purification labeling period is divided into 2: 1. The first two-thirds is used for the production of reverse liquid clean water, and the second third is the normal water for the reverse liquid clean water in the water discharge line. Although it is preferable to use the time for extrusion, this ratio may be changed as appropriate.

  Moreover, in each said embodiment, although it was decided to apply the reverse polarity voltage in the production | generation of reverse liquid purification water in 2/3 of the first half which divided the period of neutralization water purification display into 2: 1, it was discharged. It is not limited to this as long as it is possible to make the final concentration of hydrogen ions in water neutral, and for example, neutralized purified water by appropriately changing the applied reverse polarity voltage and adjusting the application time. May be generated.

  Further, for example, a pH sensor may be provided at the discharge port 19c and connected to the control unit 7, and the control unit 7 may be configured to calculate the amount of reverse liquid purified water that can generate neutralized purified water. .
