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 decomposing tap water taken in from a tap of a tap water and discharging 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 into the tank, the water is filtered in a water purification tank to obtain purified water, and the purified water is ion-decomposed in the electrolytic cell and then discharged. In addition, the ion water generator can set the pH concentration of the ionic water to be poured to “strong”, “medium”, and “weak”, and does not perform ionic decomposition in the electrolytic cell. It is also equipped with a function that can discharge the purified water filtered by.

[0003] On the front of the main body of the ionized water generator, a user operates a switch to set a selected state of water to be poured out of alkaline ionized water, acidic ionized water and purified water. Is displayed.

[0004]

However, the ion water generator has a problem that the user cannot determine the operation state. That is, in the ionized water generator, for example, when alkaline ionized water is poured out, at the beginning of the pouring, water remaining inside the water purification tank or the electrolytic tank is poured out, and this water undergoes ionic decomposition. Not done. Therefore, it is preferable that the water is not used, but the user cannot determine whether or not the water is ready to be used. Such cautions are described only in the attached instruction manual, which is very inconvenient. In addition, since the time when it is preferably not used changes according to the non-use time, the user needs to remember the date and time when the user previously used it.

[0005] In some cases, the user is notified by a buzzer every morning at the time of first use or when the setting is such that acidic ionized water not used for drinking is poured out. The buzzer may be muted.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an ion water generator that allows a user to easily determine an operating state and easily determine whether or not the user can use the apparatus. is there.

[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 ion-decomposing the filtered purified water into alkali ion water and acidic ion water. And an operation unit of a switch for selecting the water to be poured out to be the alkaline ionized water, acidic ionized water or purified water, and an ion water generator including a liquid crystal panel for displaying a setting state. It is configured to have a usability state display function for displaying whether or not to permit on the liquid crystal panel.

According to this ion water generator, the user is provided with a use permission / prohibition state display function of displaying on the liquid crystal panel a state in which the use of the poured water is permitted and a state in which the use of the water is not permitted. It is easy to determine whether the water is allowed to be used or not to be used. For this reason, it is possible to reliably prevent the user from using the water remaining in the main body at the start of pouring. In addition, since the user does not need to remember the date and time of use before, the convenience can be improved.

[0009] Specifically, it is preferable that the use availability display function determines whether or not use is permitted based on at least the non-use time. In this way, even if bacteria grow during non-use hours,
By passing water in a state where use is not permitted, the water purification tank and the electrolytic tank can be reliably cleaned.

[0010] In the setting for discharging alkaline ionized water, the availability status display function determines whether or not the use is permitted based on whether or not the current supplied to the electrolytic cell has reached a predetermined current value. It is preferable that
In this way, it is possible to reliably prevent the user from using water with insufficient ion decomposition. In addition, when tap water, which is raw water, contains a large amount of free carbonic acid, it is possible to reliably prevent the inconvenience that use is not permitted even though ion decomposition is reliably performed.

[0011] Further, the availability status display function determines whether or not the use is permitted based on whether or not the power supply to the electrolytic cell has reached a predetermined voltage in the setting for discharging the alkaline ionized water. Preferably, it is
In this way, it is possible to more reliably prevent the inconvenience that use is not permitted even though ion decomposition is reliably performed.

The availability status display function is to display characters indicating the availability status on the display panel, so that it can be easily determined that any user can use the status. It is preferable to be able to do so.

Further, a backlight means is provided on the back of the liquid crystal panel, and the display by the backlight means is made different between a use permission state and a use non-permission state as the use permission state display function. It is preferable that the operation state can be easily determined even from the position.

In this case, the availability status display function is
It is preferable that a light emission cycle of the backlight means be different between a use permission state and a use non-permission state. Alternatively, the backlight means may emit a plurality of colors, and the availability state display function may emit different colors depending on whether the use is permitted or not. Alternatively, the use permission / prohibition state display function may cause a density of a color emitted by the backlight unit to be different between a use permission state and a use non-permission state.

In the ionic water generator configured as described above, the user can easily determine whether or not to use the water to be poured out, so that the convenience in use can be further improved.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an ionized water generator 1 of the present invention. The ion water generator 1 includes a flow sensor 15, a water purification tank 14, and an electrolytic tank 19 inside the main body 2.
And a control circuit (not shown).

An operation panel 3 is provided on the front of the main body 2 as shown in FIGS. In the operation panel 3, a liquid crystal panel 4 is provided at the center, and switch operation sections 10a to 10g are provided therearound.

The liquid crystal panel 4 is of a well-known segment type provided with minute holes (not shown) for transmitting light at the back. The liquid crystal panel 4 has a level display section 5 indicating the level of ion decomposition in the electrolytic cell 19 for each step, an available state display section 6 indicating a state in which the used water can be used, and a cleaning time. A cleaning display unit 7 for indicating the replacement timing of the water purification cartridge 16 to be described later, a level display unit 8a for displaying a reference for replacement of the water purification cartridge 16, and a mark indicating which operating condition is selected. The display section 9 is formed by segment electrodes.

The operation units 10a to 10g of the switches are
This is for setting operating conditions. The operation unit 1
0a is the operation setting of "strongly alkaline", the operation unit 10b is the operation setting of "during alkali", and the operation unit 10c is "weakly alkaline".
, The operation unit 10d is an operation setting of “pure water”, the operation unit 10e is an operation setting of “acid”, the operation unit 10f is an operation setting of “washing”, and the operation unit 10g is an operation setting of “reset”.

In the present embodiment, when the operation setting is "strong alkali", all (9) levels of the level display section 5 of the liquid crystal panel 4 are turned on, and the alkaline ion having a pH value of about 9.5. Pour out the water. Further, when the operation setting is “under alkaline”, the level display section 5 of the liquid crystal panel 4 lights up six levels from below and discharges alkaline ionized water having a pH value of about 9.0. When the operation setting is set to "weak alkali", the level display section 5 of the liquid crystal panel 4 turns on three levels from below, and pours out alkaline ionized water having a pH value of about 8.5. I have.

As shown in FIG. 4, a backlight substrate 11 of the liquid crystal panel 4 is provided behind the liquid crystal panel 4. As shown in FIG. 5, the backlight substrate 11 includes a rectangular reflector 12 and a plurality of LEDs 13 disposed at predetermined intervals on upper and lower sides of the reflector 12. The LED 13 is capable of emitting three primary colors of red, green, and blue. In addition, an LED that emits red light,
LED that emits green light and LED that emits blue light
May be provided respectively.

As shown in FIG. 2, the water purifying tank 14 has a water purifying cartridge 16 disposed therein so as to be replaceable. The water purifying tank 14 is connected to a water tap via a flow rate sensor 15 for detecting a water supply amount. It is connected. The water purification cartridge 16
The antibacterial activated carbon filter 18 is arranged on the outer periphery of the laminated hollow fiber membrane filter 17 at the center, and granular calcium serving as an electrolysis accelerator is contained in the upper cap. And this water purification cartridge 1
In 6, the tap water flowing in from the bottom is permeated through the antibacterial activated carbon filter 18 and the chlorine content contained therein is removed.
The dust and the like contained through the hollow fiber membrane filter 17 are separated and removed, and purified. After that, it is poured into the electrolytic bath 19 to be ion-decomposed by calcium through the inside of the cap.

The electrolytic cell 19 is of a well-known type in which a cathode plate, an anode plate, and a diaphragm are disposed so as to partition the two plates. When a current is supplied to the bipolar plates at a predetermined set value from the control board, on the cathode plate side,
Water is reduced (takes off electrons) by reduction of water according to the following chemical formula (1) to produce hydrogen gas, and hydroxide ions are generated, indicating alkalinity. On the side of the anode plate, water is oxidized (releases electrons) according to the following chemical formula (2) to become oxygen gas, and hydrogen ions are generated, indicating acidity. Thereby, the purified water supplied from the water purification tank 14 is decomposed into alkaline ionized water and acidic ionized water. The decomposed alkaline ionized water is discharged from the discharge nozzle 20 shown in FIG. 1, and the acidic ionized water is discharged from the discharge nozzle 21 shown in FIG.

[0024]

Embedded image

In this embodiment, a three-way valve 22 is provided at the outlet of the acidic ionic water in the electrolytic cell 19, and when the user sets the operation of "purification", the three-way valve 22 flows to the discharge path of the acidic ionic 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 20 is performed by switching the polarity of the anode chamber and the cathode chamber of the electrolytic cell 19.

A control circuit for controlling the ionic water generator 1 includes a control board on which a microcomputer is mounted, and an operation unit 10a of each switch arranged on the operation panel 3 by a user.
An operation set according to an operation of 10 to 10 g is executed. Further, the display by the LEDs 13 of the backlight substrate 11 is made different depending on the set operation, that is, the type of water selected by the user and the execution state of the operation. Table 1 below shows specific settings of the present embodiment.

[0027]

[Table 1]

As shown in Table 1, depending on the type of water selected by the user, the color of light emitted by the backlight substrate 11 is blue for alkaline ionized water, green for purified water, and acidic ionized water. Is set to red. Moreover, in a state in which the use of the water discharged from the discharge nozzle 20 is permitted, the LED 13 is turned on and the usable state display section 6 is lighted. On the other hand, in the state of not permitting (non-permission), the LED 13 is made to blink, and the usable state display unit 6 is set to be turned off so as not to be displayed.

Here, whether or not to permit the use of the poured water depends on the time counted after stopping the water supply,
When the operation setting is alkaline ionized water, it differs depending on the ion decomposition level. 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 19, and bacteria may be propagated in the water. The water is displayed so as not to allow the user to use the water. Table 2 below shows conditions for shifting the display of permission to use alkaline ionized water based on the non-use time.

[0030]

[Table 2]

As shown in Table 2, when the counted non-use time is less than 10 hours, the use is not permitted for 3 seconds, and for 3 seconds, the LED 13 of the backlight substrate 11 is used. The liquid crystal panel 4 is configured to blink with blue light emission. If the non-use time is 10 hours or more and less than 24 hours, 12 seconds,
Flash with blue light. When the non-use time is 24 hours or more and less than 48 hours, the light is blinked with blue light for one minute. If the non-use time is 48 hours or more or there is no data, the light is blinked with blue light emission for 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. The transfer condition of the acidic ionic water is the same as that of the alkaline ionic water, and the transfer condition of the purified water is 0 when the non-use period is less than 30 seconds.
The only difference is in seconds.

Further, the microcomputer of this embodiment changes the display of the level display section 5 based on the value of the current supplied to the electrolytic cell 19 and the value of the applied voltage. Then, in the operation setting for discharging the alkaline ionized water, both the determination of the availability state based on the non-use time and the determination of the availability state based on the energization of the electrolytic cell 19 are cleared. Then, it is configured to allow use.

Next, control by the microcomputer will be described. When the power supply is turned on, the microcomputer of the ion water generator 1 waits until the flow rate sensor 15 detects water supply in step S1, as shown in FIG.

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 unit 10e from the operation unit 10a, or a previous setting operation by the user not operating before starting water supply. is there.

Next, in step S5, display processing of the display panel according to the operation information is performed, and then, in step S6.
Then, a backlight color setting process is executed. That is, blue is set when the set operation information is alkaline ionized water, green when it is purified water, and red when it is acidic ionized water.

Thereafter, in step S7, the non-use time by the counter is read, and in step S8, the time (flashing time) during which use is not permitted is set, and then in step S9,
The timer for the set time is started, and step S10
Then, the LED 13 starts blinking with the color scheme set in the step S6.

Next, as shown in FIG.
Then, it is detected whether or not the operation setting selected by the user is purified water. And if it is purified water, step S1
Proceeding to 2, the three-way valve 22 is positioned on the side of the ejection nozzle 20, and then proceeding to step S18. On the other hand, if the water is not purified, the process proceeds to step S13, where the three-way valve 22 is connected to the discharge nozzle 21.
After that, the process proceeds to step S14.

In step S14, it is detected whether or not the operation setting selected by the user is acidic. If it is acidic, the process proceeds to step S15, in which electricity supply to the cathode and anode is started so that acidic water is discharged from the discharge nozzle 20 to the electrolytic cell 19, and then step S1 is performed.
Proceed to 8. On the other hand, if it is not acidic, the process proceeds to step S16.

In step S16, energization of the cathode and the anode is started so that the alkaline ionized water is injected from the injection nozzle 20 into the electrolytic cell 19, and the flow proceeds to step S1.
After executing the energization level processing described later in step 7, the process proceeds to step S18.

In step S18, it is detected whether or not 1 has been input to the flag f indicating that the non-use time has already been measured by the timer. If f is not 1, the process proceeds to step S19, and if f is not 1 (f
Is 0), the process skips steps S19 to S22 to be described later and proceeds to step S23.

In step S19, it is detected whether or not the timer has counted up. If the timer has not counted up, the process proceeds to step S20 to detect whether or not the operation setting has been changed by the user operating the operation unit 10e from the operation unit 10a. And
If there is no change, the process returns to step S18. If there is a change, the process proceeds to step S21, where the count time is stored and the process returns to step 4. On the other hand, if the timer has counted up in step S19, the process proceeds to step S22, where 1 is input for f indicating that the non-use time has been measured by the timer, and the process proceeds to step S23.

When returning to step S4 after step S21, the storage time that has already been counted is subtracted from the set time in which use based on the non-use time in the newly selected operation setting is not permitted. Only the counted time is counted.

Next, as shown in FIG.
Then, a display process is performed so that the usable state display section 6 of the liquid crystal panel 4 is turned on. In step S24, the LED 13 is turned on in the same color as the blinking light emission color, and then the step S24 is performed.
At 25, it is detected whether or not the water supply has stopped. If the water supply has not stopped, the process proceeds to step S26, and if the water supply has stopped, the process proceeds to step S27.

In step S26, the user operates the operation unit 10
It is detected whether or not the operation setting has been changed by operating the operation unit 10e from a. If there is no change, the process returns to step S25, and if there is, the process returns to step S4.

Here, when the process returns to step S4 after step S26, the time count for disabling use based on the non-use time is not performed by the flag in step S22. Therefore, when the setting is changed from the setting of the purified water or the acidic water to the setting of the alkaline ionized water, an energization level process that does not permit use until a predetermined current or voltage is applied to the electrolytic cell 19 is performed. It can be used.

On the other hand, when it is detected in step S25 that the water supply has stopped, the LED 13
Is turned off, the power supply to the electrolytic cell 19 is stopped in step S28.

Then, in step S29, after storing the operation setting when the water supply is stopped, in step S30, a flag f indicating that the non-use time is measured by the timer is input as 0 (no measurement).

Thereafter, in step S31, the counter for measuring the non-use time is reset, and then in step S32
Then, the counter is started and the process returns to step S1 shown in FIG.

Next, the energization level processing by the microcomputer will be described. In the energization level process, as shown in FIG. 9, first, in step S17-1, the value of the current applied to the electrolytic cell 19 is detected.

Next, in step S17-2, it is detected whether or not the current value is a current value for displaying the level display section 5 by one level. If the current value reaches the level-up display, step S17-
If the current value does not reach the level-up display current, the process proceeds to step S17-3 through step S17-3.
Proceed to. In step S17-3, it is detected whether or not the applied voltage value is a voltage value for level-up display. Here, when the voltage value for level-up display is not reached, the process returns to step S17-2, and when the voltage value for level-up display is reached, the process proceeds to step S17-4.

In step S17-4, the level display section 5
After changing the display so that the number of one-level lighting increases, the process proceeds to step S17-5.

In step S17-5, it is detected whether or not the current value has reached the concentration (strong, medium, weak) of the alkaline ionized water set by the user. Then, when the current value reaches the set current value, the process returns. On the other hand, if the set current value has not been reached, the process proceeds to step S17-6 to detect whether or not the set current value has been reached. If the set voltage value has not been reached, the process returns to step S17-1, and if the set voltage value has been reached, a simple turn is made.

As described above, in the ionic water generator 1 of the present invention, the color arrangement of the liquid crystal panel 4 is changed by the LED 13 of the backlight substrate 11 according to the operation state set by the user's switch operation. The state can be easily determined. As a result, it is possible to prevent the user from accidentally drinking acidic ionized water that is prohibited from drinking.

Further, since there is provided an availability state display function for displaying a state in which the use of water discharged from the discharge nozzle 20 is permitted and a state in which the use of water is not permitted, the water remaining in the main body 2 is provided. It is possible to prevent the user from using water erroneously. Moreover, as the availability status display function,
Since the display unit 5 indicating a usable state is displayed and the light emission cycle of the LED 13 of the backlight board 11 is changed, it is easy for the user to determine whether or not to use the poured water. , The convenience in use can be further improved. Moreover, the user does not need to remember the date and time of previous use.

The availability status display function sets the time of prohibition of use based on the non-use time, and sets the electrolytic cell 19 in the setting of discharging alkaline ionized water.
It is determined whether or not use is permitted based on a current value or a voltage value applied to the power supply. Therefore, even if bacteria grow during non-use time, the water purification tank and the electrolytic tank can be reliably cleaned by passing water in a state where use is prohibited. Moreover, it is possible to reliably prevent the user from using water with insufficient ion decomposition. Furthermore, when a pH sensor is used, if tap water contains a large amount of free carbonic acid, there is a possibility that use will be permitted even though 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 ionic water generator 1 of the present invention is not limited to the configuration of the above embodiment. For example, in the embodiment, the state in which the use of the poured water is permitted and the state in which the use of the
Are displayed by changing the light emission cycle according to the above. However, as shown in Table 3 below, in each operation setting, light emission may be performed in light and dark colors so as to be distinguished.

[0058]

[Table 3]

Alternatively, as shown in Table 4 below, a color whose use is permitted and a color whose use is not permitted may be emitted in different colors so as to be able to be distinguished.

[0060]

[Table 4]

In the above embodiment, when the operation setting is alkaline ionized water, the display on the liquid crystal panel 4 is blue regardless of the strong, medium and weak levels, but different colors are emitted according to the levels. You may.

Further, in the above embodiment, the discharging nozzle 2
The display method of the liquid crystal panel 4 by the backlight substrate 11 is changed depending on the type of water to be poured from 0 and the use permission state and the use non-permission state. You may change the display method of
In addition, the liquid crystal panel 4 is used only when the use is permitted and when the use is not permitted.
May be changed.

[0063]

As is apparent from the above description, the ionized water generator of the present invention displays a state in which the use of water discharged from the discharge nozzle is permitted and a state in which the use of water is not permitted. Since the use availability state display function is provided, it is possible to prevent the user from using the water remaining in the main body.

Further, the function of displaying the availability state is to determine whether or not to permit use based on the non-use time. By passing water in a disallowed state, the water purification tank and the electrolytic tank can be reliably cleaned. Further, in the setting for pouring out the alkaline ionized water, in order to determine whether to permit the use based on the current value or the voltage value by energizing the electrolytic cell, the user may use water with insufficient ion decomposition. Can be reliably prevented. In addition, when tap water, which is raw water, contains a large amount of free carbonic acid, it is possible to reliably prevent the inconvenience that use is not permitted even though ion decomposition is reliably performed.

The availability status display function includes a character indicating an availability status on the display panel, or
Since the display by the backlight means provided on the back of the liquid crystal panel is made different, the user can easily determine the operation state.

Moreover, the availability status display function of the backlight means is configured to change the light emission cycle of the LED, to emit light of a different color, or to make the density of the emitted light different. With the configuration, the user can easily determine whether to use the water to be poured out, and the convenience in use can be further improved.
