[0013]
Next, the operation | movement which produces | generates ion water is demonstrated about the alkali ion water adjuster 3 comprised as mentioned above.
[0014]
The user selects the pH value of alkaline ion water or acidic ion water to be generated by the set pH input operation means 19. Then, the faucet 2 is opened. The raw water passed through the faucet 2 removes residual chlorine and impurities in the raw water at the water purification unit 4, confirms the amount of water flow through the flow rate input means 5, and dissolves calcium glycerophosphate and the like at the calcium supply unit 6 to facilitate electrolysis. After being treated with water, it is passed through the electrolytic cell 7.
[0015]
On the other hand, AC 100 V is supplied from the power-on plug 15 and converted into a control DC power source by the power source unit 16. When a positive voltage and a negative voltage are relatively applied to the electrode plates 9 and 10 of the electrolytic chamber partitioned by the diaphragm 8 in the electrolytic cell 7, an anode chamber and a cathode chamber are formed, respectively. At this time, alkaline ionized water is generated on the cathode chamber side and acidic ionized water is generated on the anode chamber side.
[0016]
Now, when water is made to flow through the main body, the flow rate input means and the control means 14 determine that water has passed. At this time, since the electrolysis conditions are set by the set pH input operation means 19, the control means 14 applies an electrolysis voltage to the electrodes via the electrolysis voltage output means 21 in order to perform electrolysis in the electrolytic cell 7. As a result, the set generated water is discharged to the discharge pipe 12.
[0017]
Further, when the flow rate input by the alkali ion water conditioner 3 with the flow rate input means 5 is less than the arbitrary flow rate of the storage means 17 (hereinafter referred to as water stoppage), the polarity of the voltage is reversed when a certain cleaning condition is satisfied.

[0018]
Next, a description will be given based on the block diagram of the control unit of the alkali ion water conditioner 3 of FIG.
[0019]
The control unit includes a ROM that stores initial values (constants) of programs and data, a RAM that stores data (variable number) necessary for operation, and an EEPROM that stores retained data even when the power is turned off. The flow rate input means 5 that can detect the flow rate such as a flow rate sensor, the electrolytic voltage output means 21 such as an FET that outputs the voltage applied to the electrolytic cell for electrolysis, and the electrolytic cell flow As a result of applying the electrolysis voltage by the electrolysis current input means 22 for inputting the current and the raw water or the electrolysis voltage output means 21, the pH value of the generated ionic water is inputted by the pH sensor or the pH value from the electrolysis current etc. Can be predicted, and the flow rate level is determined from the flow rate of the flow rate input unit 5, the electrolysis voltage of the electrolysis voltage output unit 22 is determined, the timer, the data calculation, the data A control means (MPU) 14 for performing input / output, a setting pH input operation means 19 for setting a pH value of ionic water to be generated, and an alarm means 20 for notifying a malfunction such as an overcurrent by an LCD display or a buzzer. It is configured.
[0020]
According to the flowchart of FIG. 3, when the pH value of the raw water is higher than the set pH value in the case of alkali and low in the case of acidity, the generated ion is applied when an electrolytic voltage that minimizes the ratio to be applied is applied to the electrolytic cell. When the pH value of water is higher than that of the set pH value in the case of alkaline ionized water, and in the case of acidic water, the pH value is small. A control method will be described in which the electrolytic voltage is applied at a rate smaller than the minimum rate by changing the width within a range in which ion water having a set pH value can be generated.
[0021]
As shown in FIG. 3, the control means 14 first inputs the flow rate input means 5 except when the pH value of the raw water is higher than the pH value set by the set pH input operation means 19 and when it is low in acidity. It is judged whether or not the flow rate is equal to or higher than the flow rate at which arbitrary generation of the storage means 17 is started (step 1). If it is not the production start flow rate, the process ends. If the flow rate is the generation start flow rate, the pH value desired to be generated is set by the set pH input operation means 19, so the flow rate input in step 1 or the electrolytic voltage corresponding to the flow level is set in the storage means 17 (step 2). .
[0022]
The control means 14 applies an arbitrary constant pulse width: T so that the electrolytic voltage of the storage means 17 set via the electrolytic voltage output means 21 is applied to the electrodes for electrolysis in the electrolytic cell 7: An electrolytic voltage of t _on is applied to generate ionic water (step 3).
[0023]
Thereafter, the pH value of the generated ionic water is inputted by the pH value judging means 13, and it is judged whether or not the input pH value is within the range of the pH value set by the set pH input operating means 19 (step 4). If it is within the range, the process ends. If within the range, when the alkali ion water generator, if the input pH value is greater than the set pH value (Step 5), the rate applied: continue to reduce t _on. In the case of acidic ion water generation, if the input pH value is smaller than the set pH value (step 5), the application ratio: t _on is decreased (step 6, the increase / decrease data n at this time is an arbitrary number of 0 or more) And).
[0024]
Next, it is determined whether or not the application ratio: t _on is the minimum application ratio: t _min (step 7). Minimum percentage applies: unless t _min, the flow returns to step 3. If the minimum ratio to be applied is t _min , the minimum ratio to be applied: t _min is left as it is, and the pulse width T is increased (step 8, the increment m at this time is an arbitrary number greater than or equal to 0). It is determined whether the maximum pulse width that can be set to the increased pulse width is T _max , that is, whether or not the maximum pulse width is T _max for electrolysis in the electrolytic cell so that ion water having a set pH value is discharged from the discharge pipe 12. (Step 9, T _max is an arbitrary number). If the pulse width is maximum, the process ends. If the pulse width is not the maximum, return to Step 3.
[0025]
Minimum percentage applied like this: t _min is fixed, pulse width: By ionized water set pH value T is varied can be generated range, minimum percentage applies: with t _min minor proportions An electrolytic voltage can be applied.
[0026]
Thus, according to the control method of the alkaline ionized water device of the first embodiment, the application ratio is the minimum except when the pH value of the raw water is higher than the set pH value in the alkali and low in the acidity. When the electrolytic voltage is applied to the electrolytic cell, the pH value of the generated ionic water is larger than that of the set pH value in the case of alkaline ionic water, and is smaller in the case of acidic water. The application voltage can be applied at a rate smaller than the applied minimum rate by changing the pulse width within a range in which ion water having a set pH value can be generated while fixing the minimum width of the applied rate. It becomes possible.
[0027]
【The invention's effect】
As is apparent from the above description, according to the present invention, the pH value of the raw water is higher than the set pH value, even if the conductivity of the raw water is high, except when it is higher in alkali and lower in acidity. An alkaline ionized water device capable of generating ion water having a value can be obtained.
