Next, embodiments of the present invention will be described in detail with reference to the drawings.

(Example 1)

1 is a configuration diagram illustrating an overall configuration of Example 1 of an ion water purifier as a water treatment device according to the present invention. In the figure, a water switch lever 3 is attached to the faucet 1 for supplying potable raw water such as tap water through the raw water pipe 2. The water switch lever 3 is a lever that can be switched between a position on the "raw water" side using raw water as it is and a position on the "constant water" side using raw water as an purified water supply. When the water switch lever 3 is at the purified water side, raw water is supplied from the water switch lever 3 to the main body 8 through the water supply pipe 4. The water quality switching lever 5 is provided in the main body 8 to which the water supply pipe 4 is connected.

The water quality switching lever 5 is a lever for switching the water quality taken out from the ion water purifier into purified water or electrolytic water. When the water quality switch lever 5 is on the "constant water" side, the raw water flows into the purified water cartridge 7 as it is. When the water quality switching lever 5 is the "electrolyzed water" side, raw water flows into the purified water cartridge 7 from the water quality switching lever 5 via the rectifying amount valve 6. This is for limiting the flow rate of the raw water flowing into the main body 8 to the flow rate according to the generation capacity of the electrolytic water by the electrolytic cell 11 mentioned later. The water purification cartridge 7 includes activated carbon which adsorbs residual chlorine, trihalomethane, mold odor, etc. in raw water, and hollow fiber membrane which removes ordinary bacteria or solid impurities. Purification unit to purify the purified water.

Downstream of the purified water cartridge 7, a flow rate sensor 9 is provided, and the flow rate of purified water is measured. Downstream of the flow rate sensor 9, there is provided a calcium supply section 10 that adds calcium ions to purified water from calcium glycerophosphate or calcium lactate to increase the conductivity. After the flow rate is measured by the flow rate sensor 9, the purified water flows into the electrolytic cell 11 without being passed through the calcium supply part 10 and the remaining part.

The electrolytic cell 11 is provided with the diaphragm 12 which divides the electrolyzer 11 into two, and forms two electrode chambers, and the electrode plates 13 and 14 arrange | positioned in each electrode chamber. In the normal operation of the electrolytic cell 11, a negative DC voltage is supplied from the controller 18 to be described later to the electrode plate 13, and a positive DC voltage is supplied to the electrode plate 14. It is an electrolytic part which electrolyzes water. As a result, alkaline ionized water is generated in the electrode chamber on the cathode side and acidic ionized water is produced in the electrode chamber on the anode side.

The electrolytic cell 11 includes a water discharge pipe 15 for discharging water on the electrode plate 13 side (alkali ion water when the electrode plate 13 is a negative electrode) and water on the electrode plate 14 side (electrode plate ( 14) is an anode, the drain pipe 16 for discharging the washing water which eluted the scale which consists of acidic ionized water) and the retention water in the electrolytic cell 11, the calcium, magnesium, etc. at the time of electrode plate cleaning is connected. The drain pipe 16 is provided with a switching valve 17 which opens and closes in conjunction with the water quality switching lever 5. The switching valve 17 is closed when the water quality switching lever 5 is on the "constant" side, Open on the electrolytic water side.

The controller 18 controls the whole alkali ion water purifier, controls the polarity and voltage / current of the direct current applied to the electrode plates 13 and 14, and controls electrolysis by the electrolytic cell 11. Moreover, the controller 18 detects the presence or absence of water flow and the flow rate at the time of water flow, based on the flow rate signal detected by the flow rate sensor 9.

In addition, the controller 18 includes an operation unit 24 and a storage unit 25. The calculating part 24 of the water purification cartridge 7 is based on the integrated current value which is an integrated value of the flow rate value detected by the flow rate sensor 9 and the current values supplied to the electrode plates 13 and 14 during the operation of the ion purifier. The lifetime information and the lifetime information of the electrolytic cell 11 are calculated. The storage unit 25 stores the life information calculated by the calculation unit 24. The storage section 25 is a storage section including an EEPROM, a flash memory, and the like. The storage section 25 is a nonvolatile storage section which does not lose its contents even when the power supply from the power supply section 19 is stopped.

In this embodiment, specific life information stored in the storage unit 25 includes life information of the purified water cartridge 7 and life information of the electrolytic cell 11. If there are more parts that require life management in the ion purifier, the life information of the parts can also be stored in the storage unit 25.

The life information of the purified water cartridge 7 includes the integrated flow rate value passed through the purified water cartridge 7, and the elapsed time after the replacement of the purified water cartridge 7 or from the start of use. In this embodiment, when the integrated flow rate value reaches a predetermined water flow limit flow rate value (e.g., 12000 liters), or when the elapsed time reaches a predetermined limit value (e.g., one year), the purified water cartridge 7 Is judged to have reached the end of its life, and the " cartridge replacement " lamp 38 described later is turned on. As life information of the electrolytic cell 11, the integrated energization time value which is an integrated value of the energization time of the electrolytic cell 11 is mentioned. When the integration energization time of the electrolytic cell 11 reaches 850 hours, for example, the controller 18 determines that the electrolytic cell 11 has reached the end of its life, and the water quality display lamps 31 to 34 described later (see FIG. 9). All lights up, prompting the user to contact the retailer or construction shop.

The power supply unit 19 supplies, for example, AC 100V of commercial AC power supplied from the power plug 20 to the electrode plates 13 and 14 from the DC voltage for the operation of the controller 18 and the controller 18. Is converted into a direct current voltage and supplied to the controller 18.

The panel portion 21 includes a display portion 22 and an operation portion 23. The display unit 22 is connected to the controller 18 and can display the operation state of the ion purifier and the life information stored in the storage unit 25. The operation unit 23 is connected to the controller 18 and can input operation settings for the ion purifier. Moreover, the operation part 23 can input the operation instruction which reads the lifetime information stored in the memory | storage part 25 at the time of exchange of the controller 18, the date information related to the start date of use, or the date information of a maintenance work day.

FIG. 8 is a diagram illustrating an example of an appearance of the panel portion 21. In the panel 21, in order to display the water quality generated by the ion water purifier, the "water purification" lamp 31, the "weak acid" lamp 32, the "weak alkali" lamp 33, and the "strong alkali" lamp 34 is provided. In addition, the panel portion 21 is in the state of the ion water purifier, and is in the "generating" lamp 35 indicating that the weakly acidic or alkaline ionized water is being generated, and the "in cleaning" lamp 36 indicating that the electrolytic cell 11 is being cleaned. ), A "cleaning notification" lamp 37 indicating that the electrolytic cell 11 needs to be cleaned, and a "cartridge replacement" lamp 38 indicating that the water purification cartridge 7 needs to be replaced. The lamps 31 to 38 described above correspond to the display unit 22 in FIG. 1, and each lamp is not particularly limited, but is composed of a light emitting diode having a small power consumption and a long lifetime.

In addition, the panel unit 21 is a switch for inputting an operation setting for the ion water purifier. In order to instruct the water quality generated by the ion water purifier, the "weak acid" button 39 for instructing the generation of the weakly acidic ionized water and the weakly alkaline ionized water Or "alkali" button 40 for instructing generation of strong alkaline ionized water.

When the "weak acidity" button 39 is pressed once, the ion purifier enters the weakly acidic water mode, and at the same time, the "weakly acidic" lamp 32 is turned on. If the water is passed in the state in which the "weak acid" lamp 32 is turned on and the water supply stops after the use of the weak acid water, the water quality (weak alkali or strong alkali) before pressing the "weak acid" button 39 is returned. The " integer " lamp 31 is turned on when the water quality switching lever 5 is switched to the water purification side position.

When the "alkali" button 40 is pressed once, the ion purifier enters the weak alkali mode, and at the same time the "weak alkali" lamp 33 is turned on. When the " alkali " button 40 is pressed once more, the ion water purifier changes from the weak alkali mode to the strong alkali mode, and at the same time the “weak alkali” lamp 33 is turned off and the “strong alkali” lamp 34 is turned on. When the " alkali " button 40 is pressed again, the ion purifier enters the weak alkali mode, and at the same time the “strong alkali” lamp 34 is turned off and the “weak alkali” lamp 33 is turned on. That is, whenever the "alkali" button 40 is pressed, the strength and weakness of the alkali alternately changes.

In addition, the panel unit 21 turns off the "cartridge replacement" lamp 38 after the water purification cartridge 7 is replaced, and also recognizes the cartridge replacement by the controller 18 to reset the life information of the water purification cartridge 7. The "reset" button 41 is provided. When the "reset" button 41 is kept pressed for 3 seconds or more so that the life information of the water purification cartridge 7 is not reset due to an incorrect operation, the reset is effectively performed. The buttons 39 to 41 correspond to the operation unit 23 in FIG. 1, and each button is not particularly limited, but is composed of a membrane switch having excellent waterproofness.

Hereinafter, the purified water mode operation and the electrolyzed water mode operation in the present embodiment will be described. First, the user selects a mode for generating desired water quality using the "weakly acidic" button 39 and the "alkali" button 40 of the panel portion 21, and the water quality switching lever 5 of the main body portion 8 is selected. ) Is switched to the purified water side or the electrolytic water side according to the desired water quality, the water switch lever 3 is switched to the purified water side, and the faucet 1 is opened.

Thereby, the raw water supplied from the tap 1 is supplied to the main-body part 8 via the raw water pipe 2 and the water switch lever 3 and the water supply pipe 4. When the water quality switching lever 5 is on the electrolytic water side, raw water limited to a constant flow rate through the rectifying flow valve 6 is supplied to the purified water cartridge 7, and when the water quality switching lever 5 is on the purified water side, Bypassing the valve 6, raw water with no flow rate limitation is supplied to the purified water cartridge 7. The flow rate of the purified water purified by the purified water cartridge 7 is detected by the flow rate sensor 9, the calcium powder is added by the calcium supply unit 10, and flows into the electrolytic cell 11.

The controller 18 recognizes the start of water passage when the flow rate value detected by the flow rate sensor 9 exceeds a predetermined value, and the flow rate sensor 9 starts counting pulse signals generated for each constant passage flow rate, thereby integrating the flow rate value. Start the operation of. In addition, when the controller 18 recognizes the start of water supply and the mode (or water quality) selected by the panel unit 21 is the electrolyzed water mode, the controller 18 starts to apply a voltage to the electrolytic cell 11 and, from the start of power supply to the stop of power supply. We begin measurement of this electricity supply time of time. On the other hand, in the constant water mode, the controller 18 does not apply a voltage to the electrode plates 13 and 14 of the electrolytic cell 11 and does not measure the energization time. In the water purification mode, the switching valve 17 closes as the water quality switching lever 5 switches to the water purification side, and drainage by the drain pipe 16 is stopped, and the purified water discharged from the electrolytic cell 11 is not electrolyzed. It is discharged through the pipe 15 and made available.

If the mode selected by the panel portion 21 is a strong alkali mode or a weak alkali mode, the controller 18 applies a negative voltage to the electrode plate 13 and a positive voltage to the electrode plate 14 to supply an electrolytic cell. Let (11) be electrolyzed. In the strong alkali mode, the current value flowing to the electrode plates 13 and 14 is larger than the weak alkali mode, and the amount of electric charge per unit flow rate of water is increased. As a result, the pH value of the generated alkaline ionized water is relatively high. Strong alkaline ionized water or weak alkali ionized water produced by this electrolysis is discharged through the discharge tube 15 from the electrode chamber provided with the electrode plate 13 as a cathode, and is made available. At the same time, acidic water is discharged from the electrode chamber including the electrode plate 14 serving as an anode through the switching valve 17 and the drain pipe 16.

On the contrary, if the mode selected by the panel portion 21 is a weakly acidic mode, the controller 18 applies the constant voltage to the electrode plate 13 and the negative voltage to the electrode plate 14 to cause the electrolytic cell 11 to undergo electrolysis. The weakly acidic ionized water generated by the electrolysis is discharged through the discharge tube 15 from the electrode chamber provided with the electrode plate 13 serving as the anode, and can be used. At the same time, alkaline ionized water is discharged from the electrode chamber including the electrode plate 14 serving as the cathode through the switching valve 17 and the drain pipe 16.

After the use of the desired water quality, the user locks the faucet 1 to stop the supply of raw water. When the supply of raw water stops, the flow rate value detected by the flow rate sensor 9 becomes less than the predetermined value, and the controller 18 recognizes that the water supply is stopped. When the controller 18 recognizes the stop of the water supply, the electricity supply to the electrolytic cell 11 is stopped. Moreover, the calculating part 24 of the controller 18 reads the integrated flow volume value stored in the memory | storage part 25, adds the accumulated flow volume value from this water supply start to a water supply stop, and adds to the memory | storage part ( By overwriting 25), the integrated flow rate value stored in the storage section 25 is updated.

In addition, the calculating part 24 of the controller 18 reads the integration energization time value of the electrolytic cell 11 memorize | stored in the memory | storage part 25, and adds the electricity supply time value to this electrolytic cell 11 to this read value. By overwriting the storage unit 25, the integrated energization time value of the electrolytic cell 11 stored in the storage unit 25 is updated.

The controller 18 compares the integrated flow rate value after the update of the storage unit 25 with the water passage limit flow rate value of the purified water cartridge 7 after the completion of the electrolytic operation or the water purification operation, and the integrated flow rate value is the water flow limit flow rate. When the value remains below 150 liters, the " cartridge replacement " lamp 38 blinks to indicate that the replacement time is near. After that, if the flow rate limit flow rate value is continuously exceeded, the "cartridge replacement" lamp 38 is turned on. The controller 18 compares the current date with the start date of use or the last replacement date of the purified water cartridge 7 stored in the storage section 25 after the completion of the electrolyzed water mode operation or the purified water mode operation, for example, one year. If abnormal has passed, the "cartridge replacement" lamp 38 is turned on.

Next, in the present embodiment, the maintenance work in the case where the need for replacement occurs in the controller 18 will be described. FIG. 2 is a block diagram for explaining the concept of taking over the life information of the storage unit 25 in the present embodiment. The same code | symbol is attached | subjected to the same component as the whole block diagram shown in FIG. 1, and the overlapping description is abbreviate | omitted.

Here, depending on the failure condition of the controller 18 before the replacement, the stored contents of the storage unit 25 may be destroyed, or there may be a problem in the control of reading the stored contents. Therefore, life information is stored from the storage unit 25. The description will be made separately in the case of being able to read and the case of being unable to read.

First, the case where life information can be read out from the memory | storage part 25 is demonstrated. In this case, the maintenance worker reads out the life information from the storage unit 25 of the controller 18 before the replacement and notes it, and uses the panel unit 21 for the controller 18a after the replacement to write the life information. By inputting, life information can be taken over. Hereinafter, the mode at which the lifetime information is read from the storage unit 25 of the controller 18 is set in the storage unit 25a of the controller 18a by inputting the lifetime information from the storage data confirmation mode and the panel unit 21. The mode to perform is called a memory data setting mode.

5 is a flowchart for setting the mode of the controller 18. The controller 18 is not particularly limited, but in the present embodiment, the controller 18 includes a microprocessor provided with a CPU, a program ROM, a working RAM, and an input / output interface.

The controller 18 checks the pressed state of the button of the operation unit 23 in the process of initializing (power initialize) the controller 18 immediately after turning on the power, and accordingly, the controller 18 The initialization program is recorded so as to transition to any one of the maintenance mode including the board inspection mode, the storage data confirmation mode, and the storage data setting mode when the board is inspected, and the product mode operating as a normal product. do.

In order to put the controller 18 into the board inspection mode or the storage data confirmation mode, the power plug 20 is unplugged from the outlet once, and a plurality of buttons (for example, the "alkali" button 40 of FIG. ) And the "reset" button 41) at the same time, the power supply of the ion water purifier is turned on by connecting the power plug 20 to an outlet (step S100).

Thereby, the initialization is performed immediately after the power is turned on. At this time, the controller 18 recognizes that several buttons of the operation unit 23 are simultaneously pressed and a combination of the buttons in the process of initializing the water purifier. That is, when the combination is in the substrate inspection mode (YES in step S101), the flow advances to step S104 to perform the substrate inspection, and if not (NO in step S101), the transition to the maintenance mode is instructed. It recognizes (YES in step S102), and transfers to the maintenance mode of step S105.

After the transition to the maintenance mode in step S105, the controller 18 checks which of the "reset" button 41, the "alkali" button 40, and the "weakly acidic" button 39 is pressed. That is, in step S106, the controller 18 determines whether there is an input from the "reset" button 41. If there is an input from the "reset" button 41, the controller 18 shifts to the memory data reset mode of step S200.

If there is no input from the "reset" button 41 in step S106, the controller 18 proceeds to step S107 to determine whether there is an input from the "alkali" button 40. If there is an input from the "alkali" button 40, the controller 18 shifts to the storage data setting mode of step S300.

If there is no input from the "alkali" button 40 in step S107, the controller 18 proceeds to step S108 to determine whether there is an input from the "weakly acidic" button 39. If there is an input from the "weakly acidic" button 39, the controller 18 shifts to the storage data confirmation mode of step S400. If there is no input from the "weak acidity" button 39 in step S108, the controller 18 returns to step S106.

FIG. 8 is a flowchart for explaining the operation of the controller 18 in the storage data confirmation mode. After shifting to the storage data confirmation mode of step S400, in step S401, the controller 18 displays on the display unit 22 that the storage data confirmation mode has been entered. In the display of the "memory data confirmation mode", for example, the controller 18 lights the "weakly acidic" lamp 32 and also flashes the "weak alkali" lamp 33, and at the same time the "replace cartridge" It is realized by flashing the lamp 38. Subsequently, in step S402, the controller 18 sounds a single beep three times by the buzzer to inform the maintenance worker that the storage data has been shifted into the maintenance mode confirmation mode.

Then, in step S403, the controller 18 clears the data number count to zero. Next, in step S404, the controller 18 enters a state of waiting for input from the "reset" button 41. If there is an input from the "reset" button 41 in step S404, the controller 18 proceeds to step S405 and increments the data number by one. Subsequently, in step S406, the controller 18 displays the life information of the stored data indicated by the data number on the display unit 22. Next, in step S407, the controller 18 determines whether or not the data number is last, and returns to S404 if not last. If it is the last, in step S408, the controller 18 returns to the maintenance mode of S105. Thus, by repeating step S404-step S407, the some memory data (life time information) memorize | stored in the memory | storage part 25 is displayed on the display part 22 sequentially in numerical order. The maintenance worker can read desired life information by pressing the "reset" button 41 for each of the plurality of life information stored in the storage unit 25 by the corresponding data number.

When displaying each memory data in the display part 22 in step S406, if it is the structure of the panel part 21 shown in FIG. 8, for example, the "water purification lamp" 31, the "weak acid lamp" 32, Four lamps consisting of a `` weak alkali '' lamp 33 and a `` strong alkali '' lamp 34, which display one decimal digit or one hexadecimal digit, and display the "weak acid" button 39 or the "alkali" button ( Each time 40) is pressed, the number of displayed digits in the stored data is not overlapped and displayed for each digit. In addition, it is preferable to write the conversion table of the lamp display and the corresponding number in the maintenance manual.

In addition, the display unit 22 may be provided with a liquid crystal display device that displays one digit number in seven segments, or a seven segment LED display, or the like, to display the stored data. When such seven-segment indicators are provided, when the number of digits of the indicator is smaller than the number of digits of the storage data to be displayed, the storage data can be displayed for every displayable digit as in the case of the lamp display.

Next, the storage data setting mode will be described with reference to FIG. The storage data setting mode is a mode in which the life information read from the controller 18 before replacement is set in the storage unit 25a of the controller 18a after replacement. The maintenance worker unplugs the power plug 20 from the outlet and repairs the controller 18 by replacing it with the replacement controller 18a (hereinafter, simply referred to as the controller 18). The procedure is operated to put the controller 18 in the storage data setting mode.

In the storage data setting mode, in step S301, the controller 18 indicates to the display unit 22 that the storage data setting mode has been entered. In the display of the "memory data setting mode", for example, the controller 18 flashes the "weakly acidic" lamp 32, lights up the "weak alkaline" lamp 33, and at the same time, "cartridge replacement". It is realized by flashing the lamp 38. At the same time, the controller 18 sounds a single beep three times by the buzzer to inform the maintenance worker that the storage data has been set in the maintenance mode.

Then, in step S302 and step S303, the controller 18 determines whether it is a storage data input mode or a storage data operation setting mode, and shifts to any of these modes. When reading the life information from the controller 18 before the replacement is successful, the maintenance worker presses the "alkali" button 40 to select the storage data input mode. When the life information reading is not successful, the maintenance worker presses the "weak acidity" button 39 to select the stored data calculation setting mode.

In step S302, the controller 18 determines whether or not there is an input from the "weakly acidic" button 39. If there is an input, the controller 18 shifts to the storage data calculation setting mode in step S313.

If there is no input from the "weak acidity" button 39 in step S302, the controller 18 proceeds to step S303 and determines whether there is an input from the "alkali" button 40. If there is an input from the "alkali" button 40, the controller 18 shifts to the storage data input mode of step S304. If there is no input from the "alkali" button 40, the controller 18 returns to step S302.

The maintenance worker selects the data number to be set by the "weakly acidic" button 39 and selects the numerical value to be stored in the data number by the "reset" button 41. Repeat as many times.

In step S304, the controller 18 enters the storage data input mode. Next, in step S305, the controller 18 substitutes 0 for the data number count n and clears it. Then, in step S306, the controller 18 increments the data number n by one. Next, in step S307, the controller 18 determines whether there is an input from the "weakly acidic" button 39. If there is an input from the "weakly acidic" button 39, the controller 18 returns to step S306 to increase the data number. If there is no input from the "weakly acidic" button 39 in step S307, the controller 18 proceeds to step S308 and determines whether there is an input from the "reset" button 41. If there is no input from the "reset" button 41, the flow returns to step S307. If there is an input from the "reset" button 41, the controller 18 proceeds to step S309 and counts up the contents of the data number n, and displays the contents of the data number n in step S310. Mark on. The content display of this data number n is the same as the display at the time of reading the data number of the controller 18 before replacement.

Next, the controller 18 determines whether or not the data number is final in step S311, and returns to step S307 if it is not final.

If the data number is the last, the controller 18 proceeds to step S312, waits for the input of the "alkali" button 40, and if there is an input from the "alkali" button 40, confirms the data input of all data numbers. . Next, in step S318, the controller 18 performs a process of storing the determined input data in the storage unit 25. In step S319, the controller 18 shifts to the maintenance mode. Finally, the maintenance worker pulls out the power plug 20 from the outlet, and once again connects the power plug 20 to the outlet, the controller 18 is brought into the product mode and is delivered to the user.

As described above, in the storage data operation setting mode, the lifetime information read from the storage unit 25 of the controller 18 before replacement is inputted from the operation unit 23, so that the controller 18 (reference numeral 18a in FIG. 2) after the replacement is input. It can take over to the memory | storage part 25 (25a in FIG. 2).

In addition, for the count up and the content display of the content of the data number from step S306 to step S311, a numerical value of 0 to 9 decimal number or 0 to F hexadecimal number can be input for each digit. . In addition, for each digit, there are four lamps consisting of the "integer lamp" 31, the "weak acid lamp" 32, the "weak alkali" lamp 33, and the "strong alkali" lamp 34. Alternatively, you can display one hexadecimal digit.

In addition, the display unit 22 may be provided with a liquid crystal display device for displaying a single digit in seven segments, a seven-segment LED display, or the like for one or more digits to display the stored data. When such seven-segment indicators are provided, when the number of digits of the indicator is smaller than the number of digits of the storage data to be displayed, the storage data can be displayed for every displayable digit as in the case of the lamp display.

Next, the case where life information cannot be read out from the memory | storage part 25 of the controller 18 before replacement is demonstrated. In this case, since the life information read out from the storage unit 25 before replacement is not available, the controller 18 inputs the date information related to the start date of use of the product and the date information of the maintenance work day from the operation unit 23. The lifespan information is calculated by the calculating unit 24, so that the calculated lifespan information is stored in the storage unit 25. As a result, even in the case where life information cannot be read out from the storage unit 25 of the controller 18 before replacement, the life information, although not perfect, can be transferred to the storage unit 25 of the controller 18 after replacement.

In addition, the date information related to the start date of use of the product includes the date of receipt or product warranty, the date of registration of the customer registration card in the database of the manufacturer or sales company, the date of manufacture of the product which is determined from the manufacturing lot number or the manufacturing number, The start date of use etc. which the maintenance worker heard from the user can be used.

Setting the controller 18 after the replacement in the maintenance mode and then in the storage data setting mode is the same as when the life information reading is successful.

In step S302 and step S303 of FIG. 7, the controller 18 determines whether it is a storage data input mode or a storage data calculation setting mode, and transfers to either of these modes. When the life information is not read successfully from the controller 18 before the replacement, the maintenance worker presses the "weak acidity" button 39 to select the storage data calculation setting mode.

In step S302, the controller 18 determines whether there is an input from the "weakly acidic" button 39. If there is an input from the "weakly acidic" button 39, the controller 18 proceeds to step S313, enters the storage data calculation setting mode, sounds a single beep with a buzzer, and enters the maintenance worker into the storage data calculation setting mode. Inform.

 Next, in step S314, the controller 18 inputs the data of the date information by the "reset" button 41 and the "weakly acidic" button 32 from the operation part 23 of the panel part 21. Then, as shown in FIG. The date information input here is the date information related to the start date of use of the product and the date information of the maintenance work date when the controller is replaced. In the present embodiment, these date information is an 8-digit number format indicating lift year, month, and day, each listed in the order of ｙｙｙｙｍｍｄｄ (for example, if November 21, 2008, 20081121), for a total of 16 digits. We shall input. It is also possible to omit the first two digits of the Gregorian Year and to have six digits for each date. In addition, you may abbreviate dd which shows the day.

In step S314, the "weakly acidic" button 39 is allocated to select the number of digits in 16 digits to be input, and the number of times the "reset" button 41 is pressed is used for selection of the number to be input in the corresponding digits. At this time, the number input by the display lamps 31 to 34 is displayed on the display unit 22 in binary.

Immediately after the transfer to step S314, the first one digit is input from the 16 digits. At this time, since the candidate of the input number is 0 which is an initial state, the lamps 31-34 of the panel part 21 are all turned off. Subsequently, when the "reset" button 41 is pressed once, the candidate of the input number becomes 1, and the lamps 31-33 of the panel part 21 display the lamps "0001" in order to display "0001". Is turned off, and the lamp 34 is turned on. Each time the " reset " button 41 is pressed, the input number candidate is increased by one, and the binary number represented by the lighting state of the lamps 31 to 34 of the panel 21 is increased by one. do. When the maintenance worker presses the "reset" button 41 as many times as the number of numbers he wants to input, and confirms the input number candidate in the lighting state of the lamps 31-34 of the panel part 21, the "weakly acidic" button 32 Press) once. In step S314, if there is an input from the "weakly acidic" button 32, the controller 18 goes to the next digit.

In step S314, eight digits of the first half indicating the year and month are input as date information related to the start date of use in step S314a, and then the last eight digits indicating the year and month are the date information of the maintenance work day when the controller is replaced in step S314b. Is entered. If the "alkali" button 40 is pressed after the 16-digit number is input, the input data is confirmed, and the controller 18 proceeds to step S317.

In step S317, the controller 18 calculates the use elapsed days that are the periods between the two year and the month dates using the input two year and date information, and then calculates the life information from the use elapsed days.

In calculating the lifetime information from the number of days of use, the standard daily flow rate (for example, 30 liters) and the passage flow rate (for example, 2 liters / minute) of the rectifier valve 6 in FIG. Calculate using

For example, the integration energization time value of the electrolytic cell 11 can be calculated by Formula (1).

Accumulated energizing time value = days of use elapsed x 30 x (1/2) x (1/60). (One)

Next, in step S318, the controller 18 sets the calculated lifetime information in the storage unit 25 of the controller after the exchange. Thereafter, the controller 18 shifts to the maintenance mode in step S319. Finally, the maintenance worker unplugs the power plug 20 from the outlet, and once again connects the power plug 20 to the outlet, the controller 18 is brought into the product mode and is delivered to the user.

6 is a flowchart for describing the processing contents when the memory data reset mode is selected in FIG. 5. The memory data reset mode is a process used for resetting the life information of the electrolytic cell 11 stored in the storage unit 25 when the maintenance worker replaces the electrolytic cell 11, and thus is a departure from the gist of the present invention. , Further explanations are omitted.

As described above, according to the present embodiment, when the life information can be read out from the storage by only adding the program of the controller without complicating the structure of the ion water purifier, inputting the life information read into the controller after the replacement. In addition, when the life information cannot be read out from the storage unit, the storage result can be stored in the storage unit as the lifetime information by inputting the date information related to the start of use of the product and the date of the maintenance work day. have.

Therefore, when exchanging the control part provided with the memory | storage part which memorize | stores life information, life information can be handed over to the control part after replacement | exchange, and the water treatment apparatus after replacing a control part also makes it possible to judge the parts replacement time correctly. Indicates.

The socket 26 is mounted on the controller 18 by soldering or the like, and the storage unit 25 is detachably attached to the socket 26. As a result, the memory 25 is detachable from the controller 18. The maintenance worker separates the storage unit 25 from the controller 18 before replacement, and attaches the separated storage unit 25 to the socket 26a of the replacement controller 18a. Subsequently, if the lifespan information stored in the storage unit 25 is not lost by exchanging the controller 18 with the replacement controller 18a, the lifespan information stored in the storage unit 25 is exchanged. You can take over. In the present embodiment, the memory unit 25 may be an IC that can be mounted in a socket, or may be an IC memory card such as SD memory cards including a mini SD memory card and a micro SD memory card, a memory stick, or the like. Moreover, as a structure for making the storage part 25 detachable from the controller 18, it is good also as a connector and a card slot other than a socket.

As described above, according to the second embodiment, the storage unit for storing the life information can be attached and detached from the control unit. As a result, if there is no problem in the storage contents of the storage unit before the exchange, the storage unit is transferred to the control unit after the exchange, so that the life information can be inherited by the control unit after the exchange without the need for cumbersome data setting to take over the life information. . Therefore, also in the water treatment apparatus after replacing a control part, the effect that a part replacement time can be judged correctly is exhibited.
