Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ionic water generator for electrolyzing tap water taken from a tap of a tap and discharging the ionic water as ionic water.

[0002]

2. Description of the Related Art An ion water generator of this kind is provided with a water purification tank and an electrolytic tank inside a main body, and operates a lever of a changer attached to a faucet of a tap to connect the main body through a connection pipe. Tap water is supplied to the inside, the water is filtered in a water purification tank to make purified water, and the purified water is electrolyzed in the electrolytic tank and poured out. In addition, the ion water generator can set the electrolysis level of the ionic water to be poured to “strong”, “medium”, and “weak”, and does not perform electrolysis in the electrolyzer. It is also equipped with a function that can discharge the purified water filtered by.

[0003] A panel provided with a number of switches and a display section is provided on the front of the main body of the ionized water generator. Then, by operating the switch on the panel, the user can select which type of water to pour out of the alkaline ionized water, the acidic ionized water, and the purified water, and can set the setting state on the display unit or the alkaline ionized water. An operation state including a level display indicating the level of electrolysis is displayed.

[0004]

However, in the above-mentioned ionized water generator, the order of water quality to be poured out on the panel is the order of acidic ionized water, purified water, and alkaline ionized water.
The arrangement is difficult to understand the relevance of things that can be electrolyzed, drinkable, and drinkable. For this reason, the user may feel uncomfortable, erroneously mistake what is drinkable and what is not drinkable, and may accidentally swallow non-drinkable acidic ionized water.

[0005] The level of the operation state is displayed only by the level of electrolysis of the alkaline ionized water, and the level of other purified water and the level of the acidic water are not displayed. There is a problem that the situation cannot be determined. In particular, in this type of ionized water generator, a time is set to prohibit the use of the discharged water according to the unused time. In recent years, an ionized water generator has been provided which displays the status when it becomes available. However, the user does not memorize the non-use time that has not been used, and does not know the operation state, so that the time until the usable state is displayed becomes very long. .

Accordingly, the present invention provides an ionic water generator which makes it easy for a user to understand the display on the panel to prevent accidental ingestion of acid ionic water which is not drinkable and which makes it easy for the user to understand the operating condition. The task is to provide.

[0007]

In order to solve the above-mentioned problems, an ion water generator according to the present invention comprises a water purification tank for filtering raw water and an electrolytic cell for electrolyzing the filtered purified water into alkali ion water and acidic ion water. And a panel having a switch for selecting the water to be poured out to be the alkaline ionized water, acidic ionized water or purified water and a display unit for displaying a setting state. In addition to providing a portion, an acidic display portion is provided in another portion, an alkali display portion is provided therebetween, and the alkali display portion is arranged in order of weak, medium, and strong levels from the side of the water purification display portion. .

[0008] According to the above-mentioned ionized water generator, purified water which is not electrolyzed and ionized water which is electrolyzed are divided into a part and another part. The water is separated into a part and another part. Moreover, the alkaline ionized water is arranged in order of weak, medium, and strong levels from the side of the purified water that is not electrolyzed. Therefore, it is easy to understand the relationship between electrolyzed water and non-drinkable water, drinkable water and non-drinkable water, and it is possible to suppress accidental ingestion of non-drinkable acidic ionized water.

[0009] In the ionized water generator, it is preferable that a level display section for displaying a purified water level or an electrolytic level in stages is provided on the purified water display section, the alkaline display section, and the acidic display section. This makes it possible to determine a situation in which the user is ready for use, thereby improving convenience.

In this case, it is preferable that the level display section displays a level from the purified water display section when the alkaline ionized water is poured. In addition, it is preferable that the level display section displays the level in a direction opposite to that when the alkaline ionized water is discharged when the acidic ionized water is discharged. Further, it is preferable that the color level of the level display section is changed between at least drinkable purified water and alkaline ionized water, and non-drinkable acidic ionized water. In this manner, accidental ingestion of acidic ionized water, which is impossible to drink, can be reliably prevented.

Further, it is preferable that a notification sound is output together with the level of the level display section. In this case, it is preferable that the notification sound be different for each level. This is more convenient because the user can understand the progress of the operation by ear.

As shown in FIG. 3, the water purifying tank 17 is provided with a water purifying cartridge 19 replaceable therein, and is connected to a water tap via a flow rate sensor 18 for detecting a water supply amount. It is connected. The water purification cartridge 19
In this example, an activated carbon filter 21 is provided on the outer periphery of a laminated central hollow fiber membrane filter 20, and granular calcium serving as an electrolytic accelerator is contained in an upper cap. In the water purification cartridge 19, the tap water flowing from the bottom is filled with the activated carbon filter 2.

In the present embodiment, a three-way valve 25 is provided at the outlet of the acidic ionized water in the electrolytic cell 22, and when the user sets the operation of "purification", the three-way valve 25 flows to the discharge path of the acidic ionized water. It is configured to flow the purified water so as to join the alkaline ionized water discharge path. Further, the switching when the alkaline ionized water and the acidic ionized water are discharged from the discharging nozzle 23 is performed by switching the polarity of the anode chamber and the cathode chamber of the electrolytic cell 22.

A microcomputer mounted on a control circuit (not shown) operates the operation units 4a to 4g of the operation panel 3 to select a desired water quality from the discharge nozzle among purified water, weak alkali, medium alkali, strong alkali, and acid. Of water. Among these water qualities, in the operation setting of alkaline ionized water or acidic ionized water, the level is changed based on the current value supplied to the electrolytic cell 22 or the applied voltage value, and the electrolytic current value and the flow rate are changed. The alkalinity is set based on the above calculation. When the operation is set to a slightly weak alkali, the alkaline ionized water with a pH value of about 8.5 is poured out. When the operation is set in an alkaline state, the alkaline ionized water with a pH of about 9.0 is poured out. When the operation setting is set to a high alkali level, alkali ion water having a pH value of about 9.5 is poured out.

Further, the microcomputer turns on the two LEDs 10a and 10b of the level display section 9 when the operation of the water purification is set, and turns on the usable state display section 11 when the usable state is reached. In the case of the operation setting of weak alkali, the four LEDs 10a to 10d of the level display section 9 are turned on,
When the usable state is reached, the usable state display section 11 is turned on. In the case of the operation setting in the alkaline state, the six LEDs 10a to 10f of the level display section 9 are turned on, and when the usable state is reached, the usable state display section 11 is turned on. In the case of the operation setting of strong alkali, 8 of the level display section 9
The LEDs 10a to 10h are turned on, and when the usable state is reached, the usable state display section 11 is turned on. In the case of an acidic operation setting, two Ls from the right side of the level display section 9 are set.
The EDs 10j and 10i are turned on, and when the usable state is reached, the usable state display unit 11 is turned on.

Further, the microcomputer includes the level display section 9.
LEDs 10a to 10j and usable state display unit 11
Is turned on in stages until it can be used, and a notification sound is output by a piezoelectric buzzer mounted on a circuit board each time the level is increased. Here, the usable state differs depending on the time counted after stopping the supply of water and the electrolysis level when the operation setting is alkaline ionized water or acidic ionized water. That is, the water that is poured out at the beginning of the water supply is water remaining in the washing tank or the electrolytic tank 22. Bacteria may be propagated in the water. Has not been made. Therefore, the water at the beginning of the dispensing is not used by the user, and the LED 10a of the level display unit 9 according to the level is used in order to inform the user of the progress state.
Are displayed in stages. Table 1 below shows conditions (standby time) for shifting from the use-prohibited state to the usable state based on the non-use time when the water purification operation is set, and LE.
D10a, 10b and an example of the lighting time of the usable state display unit 11 are shown.

[0025]

[Table 1]

As shown in Table 1, when the counted non-use time is less than 10 hours, there is no standby time for prohibiting use, and the device can be used immediately. In the level display section 9 according to the present embodiment, the LEDs 10a and 10b and the usable state display section 11 are arranged at 0.
Lights in order every 5 seconds, and the last usable state display section 11
It takes 2 seconds before lights up.

When the non-use time is 10 hours or more and less than 24 hours, the standby time for prohibiting use is set to 12 seconds. Then, when water flow is started, the LED 10a
Is turned on after 0.5 seconds, and LED 10b is turned on after 1 second (LED
0.5 seconds after 10a is turned on), and finally the usable state display section 11 is turned on after 12 seconds.

When the non-use time is 24 hours or more and less than 48 hours, the standby time for prohibiting use is set to one minute. When the water flow is started, the LED 10a is turned on after 0.5 seconds, the LED 10b is turned on after 1 second,
Finally, the usable state display section 11 turns on after 60 seconds.

When the non-use time is 48 hours or more or there is no data, the standby time for prohibiting use is set to 2 minutes. Here, the absence of the data occurs, for example, when the user disconnects the power cord from the outlet of the commercial power supply in a non-use state. Then, when water flow is started, the LED 10a is turned on after 0.5 seconds,
D10b lights up one second later, and finally the usable state display unit 11 lights up 120 seconds later.

When the operation setting of the alkaline ionized water and the acidic ionized water is set, the transition condition (standby time) from the use-prohibited state to the usable state is substantially the same as in the case of the purified water. Specifically, in the case of these operation settings, when the counted non-use time is less than 10 hours, a waiting time until the electrolysis current value indicating the electrolysis level reaches a reference value according to the user setting is added. You. Then, in the case of ordinary tap water, the time required for this electrolytic current value to reach the reference value is shorter than the standby time (12 seconds) in the case of 10 hours or more and less than 24 hours, and is about 8 seconds. Therefore, when the non-use time is 10 hours or more, the standby time is substantially the same as the case of the operation setting of the water purification.

Next, the control by the microcomputer will be specifically described. The microcomputer of the ion water generator 1 includes:
When the power is turned on, as shown in FIG.
Then, the flow waits until water supply is detected by the flow sensor 18.

When the water supply is detected, step S2
Then, it is detected whether or not the counter for measuring the non-use time is operating. If the counter is operating, the process proceeds to step S3, where the counter is stopped and the process proceeds to step S3.
Proceed to 4. On the other hand, if the counter is not operating, the process proceeds directly to step S4.

In step S4, the set operation information is read. Here, the set operation information is an operation set by the user operating the operation units 4a to 4e, or a previous setting operation by the user not operating before starting water supply.

Then, in step S5, the non-use time by the counter is read, and in step S6, the time for which use is prohibited is set. In step S7, the timer for the set time is started.

Next, in step S8, it is detected whether or not the operation setting selected by the user is purified water. And
If the water is purified, the process proceeds to step S9, where the three-way valve 25 is positioned on the side of the discharge nozzle 23, and then proceeds to step S14 shown in FIG. On the other hand, if the water is not purified, step S
Proceeding to 10, the three-way valve 25 is positioned on the side of the discharge nozzle 24, and then proceeding to step S11.

In step S11, it is detected whether or not the operation setting selected by the user is acidic. If it is acidic, the process proceeds to step S12, in which energization of the cathode and the anode is started so that acidic water is injected from the injection nozzle 23 into the electrolytic cell 22, and then, step S14 shown in FIG. Proceed to. On the other hand, if it is not acidic, the process proceeds to step S13, in which the energization of the cathode and the anode is started so that the alkaline ionized water is injected from the injection nozzle 23 into the electrolytic cell 22, and then the process proceeds to step S14 shown in FIG.
Proceed to.

As shown in FIG. 5, in step S14,
Perform level display processing. The level display processing will be described later in detail.

Next, in step S15, it is detected whether or not the timer for prohibiting use has counted up. If the count has not been counted up, step S16
To detect whether or not the operation setting has been changed by the user operating the operation units 4a to 4e. Here, if there is no change, the process returns to step S14, and if there is a change, the process proceeds to step S17, the count time is stored, and the process returns to step S4. This step S
When the process returns to step S4 via step 17, only the time obtained by subtracting the storage time already counted from the use prohibition time based on the non-use time in the newly selected operation setting is counted.

On the other hand, if it is determined in step S15 that the timer has counted up, the flow advances to step S18 to set the flag f indicating that the level display processing has been completed to 1
Is detected whether or not is input. If f is not 1 (if f is 0), the process proceeds to step S16 similar to the above, and if f is 1, step S19 is performed.
Proceed to.

After resetting the non-use time counter in step S19, it is detected in step S20 whether or not the water supply has stopped. If the water supply has not stopped, the process proceeds to step S21, and if the water supply has stopped, the process proceeds to step S22.

In step S21, the user operates the operation unit 4a.
It is detected whether or not there has been a change in the operation setting by operating .about.4e. If there is no change, the process returns to step S20, and if there is a change, the process returns to step S4. In addition,
When the process returns to step S4 after step S21, since the counter for measuring the non-use time has been reset in step S19, the standby time is 0 second regardless of the operation setting. Therefore, only when changing to alkaline ionized water or acidic ionized water, a short time until the electrolytic current value reaches the reference value is the standby time.

On the other hand, when it is detected in step S20 that the water supply has stopped, in step S22, the level display section 9 and the usable state display section 11 are turned off, and in step S23, the power to the electrolytic cell 22 is turned off. Stop.

Then, in step S24, the operation setting when the water supply is stopped is stored, and in step S25, the flag f indicating that the level display processing is completed is set to 0.
Enter

Thereafter, in step S26, a counter for measuring the non-use time is started, and the process returns to step S1 shown in FIG.

Next, the level display processing by the microcomputer will be described. In this level display process, as shown in FIG. 6, first, in step S14-1, it is detected whether or not a level-up time according to each operation setting has elapsed. If the level-up time has elapsed, step S1
Proceed to 4-2, and if the level-up time has not elapsed, skip the subsequent steps and return.

In step S14-2, it is detected whether or not the operation setting selected by the user is purified water. And when it is not water purification, it progresses to step S14-3, and when it is water purification, it progresses to step S14-6.

In step S14-3, after the value of the current supplied to the electrolytic cell 22 is detected, the flow proceeds to step S14-3.
In step 4, it is detected whether or not the current value is a current value that increases the display of the level display section 9 by one level (increases the number of lights). If the current value is to increase the level, the process proceeds to step S14-6. If the current value is not to increase the level, the process proceeds to step S14-6 via step S14-5. In step S14-5, it is detected whether or not the applied voltage value is a voltage value that increases in level. Here, if the voltage value does not reach the level-up display, the process returns after skipping the subsequent steps. If the voltage value reaches the level-up display, the process proceeds to step S14-6.

Steps S14-2 and S14
-4 or step S14-5 via step S14-5.
When the number reaches 6, the lighting number of the level display section 9 which is currently displayed is read.

Then, in step S14-7, the number of lights of the LEDs 10a to 10j of the level display section 9 is changed to be increased by one, and then in step S14-8, a notification sound corresponding to the number of lights is output. Here, in the case of setting of purified water and alkaline ionized water, lighting is started sequentially from the LED 10a (from the left), and in the case of setting of acidic ionized water, lighting is started from the LED 10j (from the right).
The notification sound according to the number of lightings is a sound in which the scale is changed by changing the amount of current supplied to the piezoelectric buzzer.

Next, in step S14-9, it is detected whether or not all the LEDs 10a to 10j corresponding to the operation setting selected by the user have been turned on, and whether or not the last usable state display section 11 has been turned on. When the usable state display unit 11 is turned on, the process proceeds to step S14-10, where 1 is input to the flag f indicating that the level display process has been completed, and the process returns. On the other hand, if the usable state display section 11 is not lit, the process returns.

As described above, in the ionized water generator 1 of the present invention, the purified water which is not electrolyzed into the panel and the ionized water which is electrolyzed are divided into left and right, and the purified water and the alkaline ionized water which are drinkable and the unionized water are not drinkable. Acidic ionized water is similarly divided into left and right. Moreover, the alkaline ionized water is displayed in order of weak, medium, and strong levels from the side of the purified water that does not undergo electrolysis, and has different colors. Therefore, electrolyzed or non-electrolyzed water, and
It is easy to understand the relationship between drinkable water and non-drinkable water, and it is possible to suppress accidental ingestion of non-drinkable acidic ionized water.

A level display section 9 is provided at a corresponding portion of each of the display sections 6 to 8, and the level is displayed from the LED 10a of the purified water display section 6 when the alkaline ionized water is poured out. Including the ban on use
The progress of the operation can be easily understood, and the convenience can be improved. In addition, when dispensing acidic ionic water that is not drinkable, the level is displayed in the opposite direction to when dispensing alkaline ionized water or purified water that can be dispensed. it can. In addition, it is possible to easily determine a state in which the use of the water that has been discharged from the discharge nozzle 23 is permitted and a state in which the use of the water is prohibited.
It is possible to prevent a user from using water remaining in the main body 2 by mistake. Further, the notification sound is output at the same time as the level of the level display section 9 is raised, and the notification sound is made different for each level, so that the user can understand the progress of the operation by ear, which is more convenient. It is.

Furthermore, in the present embodiment, when displaying the availability of use, the time for which use is prohibited is set based on the non-use time, and the setting for pouring out the alkaline ionized water is performed in the electrolytic cell 22. It is determined whether or not use is permitted based on the current value or voltage value to be energized. Therefore, even if bacteria grow during non-use time, the water purification tank 17 and the electrolytic tank 22 can be reliably cleaned by passing water in a state where use is prohibited. In addition, it is possible to reliably prevent the user from using water with insufficient electrolysis. When a pH sensor is used, if tap water contains a large amount of free carbon dioxide, there is a possibility that use will be permitted even if ion decomposition is reliably performed. However, in the present invention, since the determination is made based on the current value and the voltage value, the inconvenience does not occur.

The ion water generator 1 of the present invention is not limited to the configuration of the above embodiment. For example, in the embodiment, the purified water display section 6, the alkaline display section 8, and the acidic display section 7 are arranged from the left side, and the alkali display sections 8 are arranged in order of low, medium, and strong levels from the side of the purified water display section 6. However, in this order, they may be arranged from any of the upper right and lower sides.

Further, in the above embodiment, the purified water to be poured out,
Alkaline ionized water and acidic ionized water are displayed in different colors, but at least the colors of drinkable water (purified water and alkaline ionized water) and non-drinkable water (acidic water) are different. Is also good. further,
Similarly, the color scheme of the LEDs 10a to 10j arranged on the level display section 9 may be different only in the drinkable water quality and the non-drinkable water quality.

Furthermore, in the above-described embodiment, the notification sound output at the same time as the level of the level display section 9 is increased is different for each level. However, different melody may be used, and the same scale is used for each level. A different number of pronunciations may be used intermittently, and the continuous output time may be made different.

The lighting times of the LEDs 10a to 10j of the level display section 9 and the operable state display section 11 which are lit in the state of each operation setting are not limited to the configuration of the above-described embodiment, but are as shown in Table 2 below. L to light the standby time
The time may be divided by the number obtained by adding the usable state display unit 11 to the ED.
