Further, one of the strong mode, the medium mode, and the weak mode can be switched and selected by the pH adjustment button 232.
[0008]
When each mode is selected with the mode selection button 230 and the pH adjustment button 232 and water is passed, the setting of the electrolysis and the water passage state are judged by the control means 22 shown in FIG. 4, and predetermined water is discharged after electrolysis. be able to.

Next, the operation | movement at the time of producing | generating alkali ion water is demonstrated with reference to FIGS. 4-6 about the conventional built-in alkali ion water adjuster 8 comprised as mentioned above.
[0014]
The user operates the mode selection button 230 and the pH adjustment button 232 of the operation display unit 23, sets the electrolysis conditions such as the electrolysis mode and the electrolysis strength, and opens the faucet 3.

[0016]
After the water flow, the flow rate detection unit 221 in the control means 22 reads the signal from the flow rate sensor 10 and determines that this state is underwater when the flow rate level exceeds a certain level. At this time, since the electrolysis conditions are already set in the operation display control unit 222 by the operation of the operation display unit 23, the MPU 220 switches the polarity to perform the electrolysis in the electrolytic cell 13, and the electrode plate 15 becomes the cathode. Thus, the operation command is output to the electrolysis control unit 223. At the same time, a command is output to the solenoid valve control unit 224 to open the solenoid valve 18.

[0017]
The generated alkaline ionized water is discharged from the water discharge pipe 6 via the water flow pipe 17 and the water discharge pipe connection joint 7, and the generated acidic water is discharged from the auxiliary water discharge pipe 19 via the electromagnetic valve 18.
[0018]
Further, the control means 22 reverses the polarity of the voltage when the built-in alkali ion water conditioner 8 is in a water-stopping state when an adherent such as a scale made of Ca, Mg or the like adheres to the electrode plate surface. The electrode plate is washed by eluting the scale and the like into the electrolyzed water. Thereafter, when the user passes the water, it is necessary to discharge the washing water accumulated in the electrolytic cell 13 to the outside as it is for a few seconds after the start of use. During this time, the cleaning notification unit 233 of the operation display unit 23 is turned on or blinks, and a warning buzzer that does not allow drinking is sounded to notify the user that the discharged water is not drunk.
[0019]
[Problems to be solved by the invention]
Thus, the conventional built-in alkali ion water conditioner can select between alkaline ionized water and purified water, and can control the pH in the ionized water to three levels of strong mode, medium mode, and weak mode. There is no pH measurement means such as a sensor, and feedback control cannot be performed so as to keep the pH value in the ionized water in a predetermined state.
[0020]
In addition, since the conventional built-in alkaline ion water conditioner is always filled with water, when the pH sensor is attached, the internal solution such as potassium chloride (KCl) of the pH sensor is likely to be washed away. The life of the is shortened.
[0021]
Further, in the conventional alkaline ionized water device, the cleaning water in the electrolytic cell is discharged from the water discharge pipe at the time of the first water flow after the cleaning is stopped, which is not convenient.

[0039]
Next, the operation | movement at the time of producing | generating the alkali ion water is demonstrated about the built-in alkali ion water adjuster 8 comprised as mentioned above below.
[0040]
The user uses the pH setting unit 280 of the operation display unit 28 to select a predetermined concentration level according to the purpose of use (for example, pH 9.5). At this time, it can be confirmed by the concentration level display lamp 281 which pH concentration level is currently set.

If it is desired to change the digitally displayed pH value, it can be adjusted by pressing the plus button or minus button of the pH fine adjustment unit 284.
[0041]
After that, when the faucet 3 is opened, the raw water passed through the faucet 3 passes through the raw water supply pipe 4, and impurities such as residual chlorine odors and general bacteria in the raw water are removed by the water purification unit 9. After passing through the sensor 10, calcium glycerophosphate and the like are dissolved in the calcium supply unit 11 and treated with water that is easily electrolyzed, and then passed through the check valve 12 to the electrolytic cell 13. At this time, the water stop valve 24 is closed by the water pressure during water flow, so that water does not flow to the water pipe 25 through the water stop valve 24.
[0042]
After the water flow, the flow rate detector 221 in the control means 22 reads the signal from the flow rate sensor 10, and determines that this state is underwater when the flow rate level exceeds a certain level.
[0043]
At this time, based on the setting of the operation display unit 28, the MPU 220 outputs an operation command to the electrolysis control unit 223 so that the electrode plate 15 becomes a cathode by switching the polarity in order to perform the electrolysis in the electrolytic cell 13. A command is output to the solenoid valve control unit 224 to open the solenoid valve 18 and the solenoid valve 26. As a result, the electrolysis control unit 223 applies a voltage to the electrode plates 15 and 16 so that the electrode plate 15 becomes a cathode, and alkali ion water is generated in the cathode chamber of the electrolytic cell 13 and acidic ion water is generated in the anode chamber. Will be.
[0044]
The generated alkaline ionized water is discharged from the water discharge pipe 6 through the water flow pipe 17, and a part thereof is guided to the pH sensor 27 through the water flow pipe 25 and the electromagnetic valve 26. The pH value of the generated ionized water is immediately fed back by the pH sensor 27 and the pH measuring means 225, and the electrolysis output is manipulated by the electrolysis control unit 223 so as to approach the target pH value.
[0045]
When the faucet 3 is closed, the control means 22 determines that the water flow has ended based on a signal from the flow sensor 10, stops the electrolysis, and closes the solenoid valve 18 and the solenoid valve 26. At this time, the water stop valve 24 is opened, and the accumulated water in the electrolytic cell 13 can be drained. Here, by opening the electromagnetic valve 26 and the electromagnetic valve 18, accumulated water such as the electrolytic cell 13 and the water pipe is drained into the drainage tank 31. The reason why the electromagnetic valve 18 is opened is that air is introduced from the auxiliary water discharge pipe 19 to smoothly drain the water.
[0046]
When drainage is completed, the solenoid valve 18 and the solenoid valve 26 are closed. Here, the water in the pH sensor 27 is also drained at the same time, and the internal solution such as potassium chloride (KCl) of the pH sensor 27 can be prevented from flowing out.
[0047]
When the water level detection means 227 in the control means 22 detects that water has accumulated over a certain level by the water level sensor 33 in the drainage tank 31 when the drainage is completed, the drainage pump control unit 226 uses the The pump 34 is started. Thus, water in the drainage tank 31 is discharged from the auxiliary water discharge pipe 19 through the drain pipe 35 and the connection adapter 36. At this time, since the electromagnetic valve 18 is closed, the drainage does not flow into the electrolytic cell 13.
[0048]
When the water level of the drainage tank 31 falls, the water level detection means 227 detects that the water level in the drainage tank 31 has fallen by the signal of the water level sensor 33, and the drainage pump control unit 226 stops the drainage pump 34. .
[0049]
Further, the control means 22 reverses the polarity of the voltage when the built-in alkali ion water conditioner 8 is in a water-stopping state when an adherent such as a scale made of Ca, Mg or the like adheres to the electrode plate surface. The electrode plate is washed by eluting the scale and the like into the electrolyzed water. When the cleaning is completed, the cleaning water containing the scale is drained into the drainage tank 31 by opening the solenoid valve 26 and the solenoid valve 18.
[0050]
In addition, since the drainage tank 31 and the drainage pump 34 are detachable, the drainage tank 31 and the drainage pump 34 can be removed when the drainage can be drained as it is below the built-in alkali ion water conditioner 8.
[0051]
【The invention's effect】
As can be seen from the above description, according to the alkaline ionized water device of the present invention, ion water having a stable pH can be discharged, and the life of the pH sensor can be extended. Furthermore, it is possible to prevent drainage such as washing water of the electrolytic cell from being discharged from the water discharge pipe for beverages.
