[0035]
Next, the structure of the display operation part 21 of the electrolyzed water generating apparatus 1 of this invention is demonstrated.
[0036]
As shown in FIG. 2, the display operation unit 21 includes a plurality of mode display lamps 39 indicating the selected mode, a display unit 40, and the like. As shown in FIG. 3, the display unit 40 receives a transparent coating 41 that transmits light, a translucent resin pressing operation unit 42, and a pressing operation unit 42, and receives a lamp (water quality display lamp 44 and electrode cleaning). The drive unit 43 has a mortar shape that reflects and uniformly displays the light from the middle lamp 47), and has a switch-integrated structure in which a water quality indicator lamp 44, an electrode cleaning lamp 47, and a mode selection switch 45 are incorporated. Yes. When the display unit 40 is pressed (that is, when the pressing operation unit 42 provided on the display unit 40 is pressed), the driving unit 43 bends, and the driving unit 43 is bent to operate the switch 45 below to select the mode. It has come to be.
[0037]
There are a plurality of mode display lamps 39 corresponding to each mode. In the embodiment shown in the accompanying drawings, the display lamp 39a1 for the level 1 generation mode of alkaline ionized water and the display lamp for the level 2 generation mode of alkaline ionized water are used. 39a2, a display lamp 39a3 for alkaline ion water level 3 generation mode, and a display lamp 39a4 for water purification mode.
[0038]
Next, the usage method of the electrolyzed water generating apparatus 1 of this invention and the state transition of a display part are demonstrated.
[0039]
First, the operation in the case of performing electrolysis by passing water in the production mode of alkaline ionized water level 1 will be described based on the piping system diagram of FIG. 1, the block diagram of FIG. 5, and the flowchart of FIG. In FIG. 1, the flow of water is indicated by solid arrows.
[0040]
First, the user presses the display unit 40 on the operation display unit 21 on the upper surface of the apparatus (that is, the pressing operation unit 42 provided on the display unit 40) a plurality of times to select the mode display lamp 39a to be in the alkaline water level 1 mode. . In this embodiment, the mode is switched each time the display unit 40 is pressed. When the display unit 40 is pressed a plurality of times as described above so that the mode display lamp 39a is selected to be in the alkaline ion water level 1 mode, the display lamp 39a1 for the alkaline ion water level 1 generation mode is turned on. The display unit 40 remains off (that is, the water quality display lamp 44 and the electrode cleaning lamp 47 remain off). Further, if the display lamp 39a1 for the level 1 generation mode of the alkaline ionized water is left as it is, the luminance changes to about half of the normal lighting state after a predetermined time (this state is hereinafter referred to as half lighting). Similarly, when another mode is selected by pressing the display unit 40, the mode display lamp 39a of the selected mode is turned on, but it is turned on halfway after a predetermined time.
[0041]
In this state, the water tap 7 is released, and raw water such as tap water is supplied to the water supply port 2 of the electrolyzed water generating device 1 through the water supply hose 8.
[0042]
At this time, the raw water sent to the water supply port 2 is sent from the inlet 18 to the water purification cartridge 4 through the intake channel 9, and residual chlorine, musty odor, trihalomethane, agricultural chemicals, and the like are removed by the purification agent 6 in the adsorption purification tank 15. Is done. Subsequently, it is filtered by passing through the filtration membrane 5 of the filtration tank 16, and fine turbidity, bacteria, and the like are removed. In this way, by filtering the raw water through the water purification cartridge 4, the raw water is subjected to water purification treatment to produce purified water.
[0043]
The generated purified water flows out from the outlet 19 to the water supply channel 17, but passes through the flow sensor 60 when flowing through the water supply channel 17.
[0044]
When a signal is sent from the flow rate sensor 60 and the control unit 49 detects the passage of purified water in the water supply flow path 17, a voltage is applied between the anode 67 and the cathode 66 to start electrolysis. At the same time, the display unit 40 switches from the extinguished state to the blinking state of the water quality measurement lamp 44. The blinking display of the water quality measurement lamp 44 on the display unit 40 is for notifying that the electrolyzed water is not properly generated.
[0045]
Most of the purified water flowing through the water supply channel 17 is supplied from the inlet 54 to the electrolyte addition unit 50 through the water supply main channel 14, and the remaining part is supplied from the bypass port 94 through the bypass channel 10 to the cathode chamber of the electrolytic cell 62. 65.
[0046]
The purified water supplied to the electrolyte addition unit 50 is provided with a dissolved electrolyte. Most of the water to which the electrolyte is applied is supplied from the upper outlet 93 through the main supply passage 13 and a small part of the remaining water is supplied from the lower outlet 92 through the auxiliary supply passage 12 together. It flows into the flow path 11 and is supplied from the inlet 68 to the cathode chamber 65 and the anode chamber 64 of the electrolytic cell 62. At this time, after water is supplied to the position where the upper outlet 93 is formed, the water is mainly discharged from the upper outlet 93 and stays in the electrolyte adding part 50 to some extent. Water to which the electrolyte is sufficiently applied flows out from the electrolyte addition unit 50.
[0047]
At this time, most of the purified water that has passed through the water purification cartridge 4 is supplied to the electrolytic cell 62 after passing through the electrolyte addition unit 50, so that the electrolyte concentration in the water supplied to the electrolytic cell 62 is sufficiently ensured. As a result, electrolysis in the electrolytic cell 62 is efficiently performed.
[0048]
Then, alkaline ionized water is generated in the cathode chamber 65 and acidic ionized water is generated in the anode chamber 64 by electrolysis. Alkaline ion water generated in the cathode chamber 65 flows into the water discharge pipe 3 mainly from the outlet 69 having a large opening area among the water outlet 95 and the outlet 69, and is led out of the apparatus. On the other hand, the acidic ion water generated in the cathode chamber 64 is discharged out of the apparatus through the discharge port 72 through the discharge port 70.
[0049]
Since the water in the electrolytic cell 62 is not replaced with the newly introduced water until a constant total flow rate flows for a certain period of time within a predetermined flow rate range after the water flow is detected and the electrolysis starts, inappropriate water And the water quality measurement lamp 44 of the display unit 40 is blinked.
[0050]
When a suitable water state is reached after a certain time, that is, after a certain total flow rate has flowed, the water quality measurement lamp 44 of the display unit 40 changes to lighting, and the user can easily recognize that suitable water has been produced. .
[0051]
In addition to this embodiment, when a plurality of different color lamps are used as the water quality measurement lamp 44, the color of the lamp can be freely changed depending on whether it is inappropriate water or suitable water. You may make it show.
[0052]
In addition, as shown in FIG. 5, a warning sound generator 48 may be provided so that a warning sound is generated when inappropriate water is used to notify the user that the water is inappropriate. In addition to the display by the display unit 40 as described above, the user can recognize that it is inappropriate by a warning sound, and can eliminate erroneous recognition without oversight.
[0053]
In addition, when the amount of water flowing into the electrolyzed water generator increases from an appropriate water state to an excessive flow rate, the electrolysis capability may reach a limit and may not reach a predetermined pH. When the control unit 49 determines that this state has been reached based on a signal from the flow sensor 60, the water quality measurement lamp 44 of the display unit 40 is caused to blink more quickly than the normal blinking state (this state is referred to as fast blinking). ), Let the user know that the flow rate is excessive, and inform the user to adjust the flow rate of the water flowing into the electrolyzed water generating device to be within the predetermined flow rate.
[0054]
In addition to this embodiment, in the case where a plurality of different color water quality measurement lamps 44 are provided in the display unit 40, the lamp color can be freely adjusted depending on the excessive flow rate when the water is inappropriate and when the water is suitable. You may make it change and let you know. In this case, the color of the lamp may be further varied depending on whether the water is unsuitable due to an excessive flow rate at the time of unsuitable water or the case of unsuitable water for other reasons.
[0055]
In the case where the warning sound generating unit 48 is provided, a warning sound may be generated to notify the user while the warning sound is determined to be inappropriate due to the excessive flow rate.
[0056]
In the above operation, if the direction of the voltage applied in the electrolytic cell 62 is reversed, the cathode chamber 65 functions as an anode chamber to generate acidic ion water, and the anode chamber 64 serves as the cathode chamber. The alkaline ionized water is generated by fulfilling the above function. At this time, acidic water flows into the water discharge pipe 3 from the outlet 69 and is led out of the apparatus, and alkaline water is discharged from the discharge pipe 72 through the discharge port 70 to the outside of the apparatus.
[0057]
Next, the operation when the supply of water into the electrolyzed water generator 1 is stopped will be described.
[0058]
When the water supply to the electrolyzed water generating device 1 is stopped by closing the water tap 7 by the user, the flow of water in the water supply flow path 17 is stopped and the flow rate sensor 60 enters a water stop state. Therefore, the control unit 49 determines that the water is stopped.
[0059]
At this time, if necessary, a reverse voltage is applied between the electrodes 66 and 67 to remove the scale on the surfaces of the electrodes 66 and 67, and then the voltage is applied between the electrodes 66 and 67 in the electrolytic cell 62. Stopped.
[0060]
Simultaneously with the application of the reverse voltage, the electrode cleaning lamp 47 is lit to display that the display unit 40 is in the process of electrode cleaning. Thereafter, drainage of the accumulated water remaining in the downstream water flow path, the electrolyte addition unit 50, and the electrolytic cell 62 from the water purification cartridge 4 in the electrolyzed water generating device 1 is started when the drain valve 30 opens. After draining is completed, the electrode cleaning lamp 47 of the display unit 40 is turned off.
[0061]
At this time, drainage of the accumulated water that has accumulated in the downstream water channel, the electrolyte addition unit 50, and the electrolytic cell 62 from the water purification cartridge 4 in the electrolyzed water generating device 1 is started.
[0062]
In addition, when the water is again flowed into the electrolyzed water generating apparatus 1 during the electrode cleaning and within a predetermined time after the electrode cleaning is completed, the display unit 40 switches the electrode cleaning lamp 47 from the state in which the electrode cleaning lamp 47 is turned on simultaneously with the water flow. Since the electrode cleaning water is mixed until it changes to the 47 flashing state and flows for a certain time in the predetermined flow rate range, it is determined that the water is inappropriate, and the electrode cleaning lamp 47 of the display unit 40 is flashed. At the same time, there is a danger of harming the body when drinking water in this state, so the warning sound generator 48 may generate a warning sound to warn.
[0063]
In addition to this embodiment, in an embodiment having a plurality of lamps of different colors, the electrode cleaning water is mixed as described above and it is determined that the water is inappropriate. The lamp color may be changed freely and notified by single lighting or simultaneous lighting of a plurality of lamps when it is determined that there is.
[0064]
