[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ion water conditioner that electrolyzes raw water such as tap water to produce alkali ion water and acidic ion water.
[0002]
[Prior art]
An ion water conditioner electrolyzes raw water such as tap water to obtain ionic water. Alkaline ionic water is used for drinking, medical use, etc. ing.
[0003]
Here, in recent years, a continuous electrolysis type ion water conditioner has become widespread. This ion water conditioner electrolyzes tap water or the like in an electrolytic cell to generate acidic ion water on the anode side and alkali ion water on the cathode side.
[0004]
Hereinafter, a conventional continuous electrolysis type ion water conditioner will be described.
A conventional ion water conditioner outputs a flow rate sensor that detects the flow rate of raw water flowing into the water conditioner, and a voltage (hereinafter referred to as “electrolysis voltage”) that is applied to an electrolytic cell to electrolyze the raw water. Electrolytic voltage application means, pH sensor for detecting the pH value of the generated alkaline ionized water or acidic ionized water (hereinafter referred to as “ionic water”) or raw water, current flowing in the electrolytic cell (hereinafter referred to as “electrolytic current”) )), A control means for determining the flow level from the flow rate detected by the flow sensor and determining the electrolytic voltage to be output to the electrolytic voltage application means, and for calculating a timer and data, etc., and for the ionic water to be generated It comprises a pH setting means for setting a pH value with a switch, a storage means for storing data such as an electrolysis voltage, and an alarm means for informing a malfunction with an LED or a buzzer.
[0005]
Then, when raw water is poured into such a water conditioner and the flow rate detected by the flow sensor is equal to or higher than an arbitrary flow rate of the storage means (hereinafter referred to as “water flow”), the flow rate level at which the set pH value has passed. Is determined from any initial data stored in advance in the storage means, and the electrolysis voltage is applied. Thereafter, the set pH value and the pH value are compared at a constant rate, and the applied electrolysis voltage is increased or decreased at a constant rate until the pH value becomes, for example, ± 0.1 of the set pH value. Then, the electrolytic voltage when the pH value is stabilized is stored in the storage means as the electrolytic voltage corresponding to the flow rate level of the set pH value.
[0006]
Similarly, when the set pH value is switched or the flow rate level is changed, an electrolytic voltage that is arbitrary initial data corresponding to the changed set pH value or changed flow rate level is determined from the storage means, The electrolytic voltage is applied. When the pH value of the generated ionized water is stabilized at ± 0.1 of the set pH value, the electrolysis voltage at that time is stored in the storage means.

[0009]
In addition, when ionic water is generated at a flow rate level other than the flow rate level at which the water first flows, an arbitrary electrolysis voltage stored in the storage means is applied at the start of water flow at the new flow level. It takes time to stabilize the pH value of the ionic water generated by the difference within a predetermined range of the set pH value.
[0010]
Furthermore, when the operation shifts from water stoppage to water flow or when the set pH value is switched from a small value to a large value in the water flow state, an electrolytic voltage corresponding to the flow rate level of the changed pH value is applied. However, in this case, it takes time until the pH value of the generated ionic water approaches the predetermined range of the set pH value.
[0011]
And when an overcurrent flows during the production | generation of ionic water, an overload will be applied to a control means and operation | movement of a water conditioner will become unstable.

Further, according to the present invention, when the operation shifts from water stoppage to water passage or when the set pH value is switched to a large value, the pH value of the ionic water is within a predetermined range of the set pH value within a short time. An object of the present invention is to provide an ion water conditioner that can be stabilized.
[0015]
An object of the present invention is to provide an ion water conditioner in which an overload due to an overcurrent is not applied to the control means.
[0016]
[Means for Solving the Problems]
In order to solve this problem, the ion water adjuster of the present invention outputs a voltage applied to a pair of electrode plates that electrolyze the raw water and a flow rate sensor that detects the flow rate of the raw water flowing into the water adjuster. An electrolytic voltage application means, a pH sensor for detecting the pH value of the generated ionic water or raw water, an electrolytic current sensor for detecting the current flowing in the electrolytic cell in which the electrode plate is installed, and the pH value of the ionic water to be generated The pH setting means to set, the increase / decrease of the electrolysis voltage applied to the electrode plate, and the detection speed of the pH value are changed according to the pH value level of the ionic water detected by the pH sensor, and the pH value of the ionic water is changed. And a control means for setting the pH within a predetermined range. Thereby, the arrival time to within the predetermined range of the setting pH value in ion water can be shortened.
[0017]
In this ion water conditioner, the control means calculates the electrolysis voltage at the other flow level from the flow level and the electrolysis voltage when the pH value of the first generated ionic water falls within the predetermined range of the set pH, This electrolytic voltage can be applied to the electrode plate. Thereby, the pH value of ionic water can be stabilized within a predetermined range of the set pH value in a short time.
[0018]
Further, in this ion water conditioner, when the control means shifts from water stoppage to water flow and when the setting is switched from a small pH value to a large pH value during the water flow, a predetermined time from the start of generation of the ion water. The maximum electrolysis voltage can be applied for a certain period of time after the elapse of time, and then the set electrolysis voltage can be applied. Thereby, the pH value of ionic water can be stabilized within the set pH value within a short time.
[0019]
Furthermore, in this ion water conditioner, the electrolysis voltage in the electrolytic cell can be detected by applying a small electrolysis voltage for a certain time from the start of the production of ionic water by the control means. As a result, an excessive electrolytic current is prevented from flowing in advance, and the control means is not overloaded by the overcurrent.

[0031]
The ion water adjuster 3 having such a piping structure is provided with a control means 14 such as an MPU that controls the operation of the ion water adjuster 3.
[0032]
As shown in detail in FIG. 2, the flow rate sensor 5, the electromagnetic valve 11, and the pH sensor 13 described above are electrically connected to the control unit 14, and the flow rate data of the introduced water is transferred from the flow rate sensor 5 to the control unit 14. The opening and closing of the bypass pipe 23 is controlled by the control means 14, and the pH value data of the water passing through the electrolytic cell 7 is sent from the pH sensor 13 to the control means 14.
[0033]
Further, the control means 14 includes an electrolytic voltage applying means 21 such as an FET for applying an electrolytic voltage to the electrode plates 9 and 10, and an electrolytic current flowing through the electrolytic cell 7 by the electrolytic voltage applied by the electrolytic voltage applying means 21.

[0034]

[0035]
Such control means 14 is operated by a direct current that is taken in from the power-on plug 15 and converted from an alternating current in the power supply unit 16.
[0036]
Next, the operation | movement which produces | generates ion water is demonstrated about the ion water conditioner 3 in this Embodiment comprised as mentioned above.
[0037]
First, the user inputs the pH value of alkaline ion water or acidic ion water to be generated by the pH setting means 19 and opens the faucet 2. As a result, the raw water passed from the raw water pipe 1 is freed of residual chlorine and impurities in the raw water by the water purification unit 4, the amount of water flow is detected by the flow sensor 5, and calcium glycerophosphate and the like are dissolved by the calcium supply unit 6. After being treated with electrolyzed water, it is guided to the electrolytic cell 7.
[0038]
On the other hand, for example, a voltage of AC 100 V is supplied from the power-on plug 15 and is converted into a control DC voltage by the power supply unit 16. Then, a positive voltage and a negative voltage, which are voltages having different polarities, are applied to the electrode plates 9 and 10 provided in the electrolysis chambers 7a and 7b. Thereby, an anode chamber and a cathode chamber are formed, and alkali ion water is generated on the cathode chamber side and acidic ion water is generated on the anode chamber side.
[0039]
When the flow rate level detected by the flow rate sensor 5 exceeds a predetermined value, the control means 14 determines that water is flowing. At this time, since the electrolysis conditions are set by the pH setting means 19, the control means 14 applies an electrolysis voltage for performing electrolysis in the electrolytic cell 7 to the electrode plates 9 and 10 via the electrolysis voltage application means 21. As a result, the generated water at the set pH value level is discharged from the water discharge pipe 12.
[0040]
When the ion water conditioner 3 is in a water-stopped state or when a predetermined cleaning condition is satisfied, the polarity of the voltage applied to the electrode plates 9 and 10 is reversed and the electrode plates 9 and 10 are cleaned. After completion of the cleaning, the electromagnetic valve 11 is opened by the control means 14 and the cleaning water is discharged from the bypass pipe 23 and the drain pipe 18.
[0041]
Here, a process of generating ionic water within a predetermined range of the set pH value from raw water in the ionic water conditioner 3 in the present embodiment will be described with reference to FIG. In the present embodiment, the case of generating ionic water within a range of ± 0.1 of the set pH value will be described, but the range for the set pH value can be freely defined. Moreover, although the flow level is made into four steps, this can also be set freely.
[0042]
In FIG. 3, when the flow rate detected by the flow rate sensor 5 and input to the control unit 14 is not equal to or higher than the flow rate value stored in the storage unit 17 (hereinafter referred to as “water stop”), the electrolytic voltage output is stopped. (Step 1).
[0043]
On the other hand, when the flow rate by the flow rate sensor 5 is not less than the flow rate value stored in the storage unit 17 (hereinafter referred to as “water flow”), it is determined whether or not the mode set by the pH setting unit 19 is the water purification mode. (Step 2), the electrolysis voltage output is stopped in the water purification mode. In the alkaline or acidic mode, it is determined whether 20 to 40 seconds have elapsed from the start of water flow, that is, whether the pH value control may be permitted (step 3). And if it is prohibition, it will return to step 1, and if it is permission, the pH value of produced | generated ion water will be input into the control means 14 from the pH sensor 13 (step 4). Thereafter, it is determined whether or not the initial setting of the pH value control speed has been completed (step 5).
[0044]
If the initial setting is completed, an electrolytic voltage is applied (step 6). If not set, the control speed (about 0.5 to 2 seconds) is initially set, and the electrolysis voltage of arbitrarily set initial data stored in the storage means 17 is applied (step 7).
[0045]
After step 6, the set pH control speed is counted, and if the count is not over, the process returns to step 1 (step 8). If the count is over, it is determined in step 4 whether the pH value of the ionic water input to the control means 14 is within ± 0.1 of the set pH value (step 9). If there is, the control speed 4 (about 2 to 8 seconds) is set. If it is out of the range, it is judged whether the pH value of the ionic water is within the range of ± 0.2 of the set pH value (step 10), and if it is within the range, the control speed 3 (about 2 to 8 seconds) is set. Is done. If it is outside the range, it is judged whether the pH value of the ionic water is within the range of ± 0.3 of the set pH value (step 11). If it is within the range, the control speed 2 (about 2 to 8 seconds) is set. Is done. Furthermore, if it is out of the range (step 12), the control speed 1 (about 0.5 to 2 seconds) is set.
[0046]
If the pH value of the ionic water is within ± 0.1 of the set pH value, the electrolysis voltage at that time is stored in the storage means 17 as an electrolysis voltage corresponding to the set pH value and the flow rate level (step 13). If it is out of the range, the electrolysis voltage is increased or decreased to be within the range (step 14), and the process returns to step 1.
[0047]
As described above, according to the ion water conditioner according to the present embodiment, the increase / decrease of the electrolysis voltage applied to the electrode plates 9 and 10 and the detection speed of the pH value are determined based on the pH value of the ion water detected by the pH sensor 13. Since the pH value of the ionic water is set within the range of ± 0.1 of the set pH by changing according to the level, the time required to reach the range of ± 0.1 of the set pH value in the ionic water is shortened. can do.
[0048]
Here, pH value control of ionic water when the flow rate level of raw water changes will be described.
[0049]
In FIG. 4, water is first passed through the ion water conditioner 3, and the initial setting of the electrolytic voltage is performed by steps 1 to 14 as described above at an arbitrary flow rate level at a certain pH value. Then, it is determined whether or not the initial setting has been completed (step 15). If it has not been completed, the initial setting is performed. If completed, an electrolysis voltage other than the electrolysis voltage corresponding to the initially set flow level is calculated at each set pH value and stored in the storage means 17 (step 16).
[0050]
Here, as a calculation method, the difference between the electrolytic voltage set in the initial setting and the electrolytic voltage data corresponding to the flow level of the set pH value stored in advance in the storage unit 17 is obtained, and the maximum value and the minimum of the difference are obtained. Increase / subtract within the range of values to determine the electrolysis voltage at other flow levels.
[0051]
In each set pH value, the second and subsequent water flows update and store the data previously stored in the storage unit 17 for the electrolytic voltage set in steps 1 to 14.
[0052]
As described above, according to the ion water conditioner according to the present embodiment, the flow rate level and electrolysis when the pH value of the ionic water generated by first passing water is within the range of ± 0.1 of the set pH. Since the electrolysis voltage at other flow levels is calculated from the voltage and this electrolysis voltage is applied, when the flow level changes, the electrolysis voltage value obtained by the calculation is applied, and this is related to the water quality. In addition, the pH value of the ionic water can be stabilized within a range of ± 0.1 of the set pH value in a short time.
[0053]
Next, the pH value control of ionic water when the operation is shifted from water stoppage to water passage and the set pH value is switched to a large value will be described.
[0054]
After the raw water is passed through the ion water conditioner, it is determined in FIG. 5 whether or not m seconds (about 1 to 2 seconds) have elapsed since the start of generation in the alkaline or acidic mode (step 17). If not, in step 18, an electrolytic voltage (hereinafter referred to as “electrolytic voltage X%”) of about 10 to 15% of the capability is applied. If it has elapsed, it is determined whether or not n seconds (about 3 to 5 seconds) of generation has elapsed (step 22). Then, if it has elapsed, an electrolytic voltage corresponding to the set pH value and flow rate level is applied (step 23). Further, if it has not elapsed, it is determined whether or not the pH setting value has been switched from the small value to the large value during the passage from the stop water or the passage of water (step 24). If so, 100% electrolysis voltage is applied (step 25), otherwise the process proceeds to step 23.
[0055]
On the other hand, when the electrolytic voltage X% is applied in step 18, the electrolytic current value in the electrolytic cell 7 is input from the electrolytic current sensor 22 to the control means 14 (step 19). Then, the input electrolysis current value is compared with the maximum electrolysis current value stored in the storage means 17 (step 20). As a result, when the input electrolysis current value is larger than the maximum electrolysis current value, it is determined as an overcurrent, the application of the electrolysis voltage is stopped, and the alarm means 20 issues an alarm to the operator (step 21). . On the other hand, if it is small, the electrolysis voltage X% is applied as it is.
[0056]
As described above, according to the ion water adjuster according to the present embodiment, when transition from water stoppage to water flow or when the setting is switched from a small pH value to a large pH value during water flow, the generation of ionic water is started. Since the maximum electrolysis voltage is applied for a certain period of time after the elapse of time, and then the set electrolysis voltage is applied, the pH value of the ionic water is stable within the set pH value within a short time. It can be made.
[0057]
In addition, at the set pH value, the electrolytic current in the electrolytic cell is detected by applying a small electrolysis voltage for a certain time from the start of the production of ionic water, so that an excessive electrolysis current is prevented from flowing in advance. The overload is not applied to the control means 14 due to the overcurrent.
[0058]
【The invention's effect】
As described above, according to the present invention, an increase or decrease in the electrolysis voltage applied to the electrode plate and the detection speed of the pH value are changed according to the level of the pH value of the ionic water detected by the pH sensor. Since the pH value is set within the predetermined range of the set pH, an effective effect that the time required for the ion water to reach the predetermined range of the set pH value can be shortened.
[0059]
In addition, according to the present invention, the electrolysis voltage at another flow rate level is calculated from the flow rate level and the electrolysis voltage when the pH value of the ionic water generated by first passing water is within the predetermined range of the set pH. Since this electrolytic voltage is applied, by applying the electrolytic voltage value when the flow level changes, regardless of the water quality, the pH value of the ionic water is set to the predetermined pH value within a short time. The effective effect that it can stabilize within the range of this is acquired.
[0060]
Furthermore, according to the present invention, the maximum electrolysis voltage after a lapse of a predetermined time from the start of generation of ionic water when the water flow is changed from water stoppage to water flow or when the setting is switched from a small pH value to a large pH value during the water flow. Is applied for a certain period of time, and then the set electrolysis voltage is applied, so that the pH value of the ionic water can be stabilized within the set pH value within a short time. Is obtained.
[0061]
According to the present invention, at the set pH value, an electrolysis voltage in the electrolytic cell is detected by applying a small electrolysis voltage for a certain time from the start of the generation of ionic water, so that an excessive electrolysis current flows. Is effectively prevented, and an effective effect that the control means is not overloaded by the overcurrent is obtained.
