BACKGROUND OF THE INVENTION
The present invention relates to an electrolyzed water generating apparatus.
[0002]
[Prior art]
As one type of electrolyzed water generating device, an electrolyzer having a pair of electrodes, a water supply line for supplying electrolyzed water into the electrolyzer, an outflow pipe for allowing electrolyzed water in the electrolyzer to flow out, and a water supply pipe The electrolytic operation is controlled in such a manner that the electrolyzed water supplied to the electrolytic tank through the passage is electrolyzed in the electrolytic tank, and the generated electrolytic generated water flows out to a predetermined place through the outflow valve provided in the outflow pipe. There is a first-stop type electrolyzed water generating device that includes a control device and closes the outflow valve to stop the supply of the electrolyzed water into the electrolyzer.
[0003]
In the electrolyzed water generating apparatus, during electrolysis operation, the outflow valve is opened to supply electrolyzed water into the electrolytic cell through the water supply pipe, and the electrolyzed water generated in the electrolytic cell is passed through the outflow valve to a predetermined level. When the electrolysis operation is stopped, the outflow valve is closed to stop the outflow of the electrolyzed water from the outflow valve at the same time, and at the same time, the electrolytic cell through the water supply line is covered. The water supply of electrolyzed water is stopped.
[0004]
[Problems to be solved by the invention]
By the way, since the electrolyzed water generating device is a first-stop type device, when the electrolysis operation is stopped, a high water pressure is always applied from the supply source side of the electrolyzed water, and it is durable by the constantly applied water pressure. There is a risk that water will leak due to a decline in the properties. For this reason, in order to maintain high water pressure resistance in the water supply pipeline, the electrolytic cell, and the outflow pipeline, and in consideration of leakage of water when there is no monitoring person such as at night when the electrolysis operation is stopped, the water supply pipeline, As each component constituting the electrolytic cell and the outflow pipe, one having durability more than necessary is used.
[0005]
In order to cope with this, a method is conceivable in which a main plug is disposed in the vicinity of the supply source of the electrolyzed water and the main plug is closed when the electrolysis operation is stopped. However, depending on the installation state of the electrolyzed water generating device, there is a problem that the position of the main plug is located away from the installation location of the electrolyzed water generating device. In addition, once the main plug is closed, after that, forcing maintenance of the electrolyzed water generation device, for example, maintaining water quality in the device and preventing freezing, it is impossible to forcibly supply and discharge water to the device at regular intervals. become.
[0006]
Accordingly, an object of the present invention is to address these problems in an electrolyzed water generating device of the type.
[0007]

[0017]
The power application mechanism 40 includes a DC power supply 41 and an electromagnetic switch 42, and each electrode of the DC power supply 41 is connected to the electrodes 13 a and 13 b in the electrolytic cell 10 via the electromagnetic switch 42. The DC power supply 41 is of a voltage variable type in which the applied voltage is variable. The electromagnetic switch 42 opens and closes and functions to interrupt the application of voltage to the electrodes 13a and 13b, and reverses the polarity of the applied voltage to the electrodes 13a and 13b by a switching operation. In the power application mechanism 40, a current sensor 43 is interposed in the middle of a connection circuit that connects the electromagnetic switch 42 and the electrode 13b.
[0018]
The control device 50 controls the operation of the electrolyzed water generating device. The control device 50 operates when the power is turned on by the main switch 51, controls the water supply control valve 27, controls the switching of the flow path switching valve 31, and controls the electromagnetic switching. By controlling the opening / closing / switching of the vessel 42 and controlling the opening / closing of the discharge control valve 34c, the electrolyzed water generating device is operated and the operation is interrupted or stopped.
[0019]
In the electrolyzed water generating apparatus, when the operation is stopped, the water supply control valve 27 and each discharge valve 34c are closed, and the electromagnetic switch 42 is opened, and the main switch 51 of the control apparatus 50 is turned on. As a result, the electrolysis operation of the electrolyzed water generator is started.
[0020]
When the main switch 51 of the control device 50 is turned on and the outflow valve 33c and / or the outflow valve 33d are in an open state, the water supply control valve 27 is opened and the electromagnetic switch 42 is closed, and the electrolysis operation is started. Is done. At this time, the tap water in the water pipe 20a is supplied as electrolyzed water to the second water supply pipe 23 of the water supply mechanism 20 through the water purifier 21, and is passed through the branch pipes 23b and 23c on the tip side of the pipe main body 23a. The electrolytic chambers 14a and 14b are supplied at a constant flow rate. Further, a voltage is applied to the electrodes 13a and 13b from the DC power source 41 through the electromagnetic switch 42, and the electrolyzed water supplied to the electrolysis chambers 14a and 14b is constant in the electrolysis chambers 14a and 14b. It is electrolyzed with the electrolysis voltage of the voltage and is generated in electrolyzed water.
[0021]
The generated electrolyzed water is, for example, acid water generated in the electrolysis chamber 14a on the positive electrode side, through the flow path switching valve 31 of the outflow mechanism 30, through the outflow conduit 33a, and the outflow valve 33c in the open state. It is supplied to the place of use through. Further, for example, alkaline water generated in the electrolysis chamber 14b on the negative electrode side is supplied to the place of use through the flow path switching valve 31 of the outflow mechanism 30 through the outflow pipe 33b and through the open outflow valve 33d. Is done.
[0022]
In the electrolyzed water generating apparatus, the electrolysis state is set to one cycle, and thereafter, the electromagnetic switch 52 is opened by operating the manual changeover switch 52 of the control device 50 to interrupt the electrolysis operation. By re-operating, the electromagnetic switch 42 is switched to switch the polarity of the voltage applied to the electrodes 13a and 13b to each other, and the flow switching valve 31 is switched to restart the electrolysis operation.
[0023]
In this case, the flow path switching valve 31 is switched from the state shown by the solid line in FIG. 1 to the state shown by the two-dot chain line. For example, the alkaline water generated in the electrolysis chamber 14a on the negative electrode side Through the outflow pipe 33b and through the outflow valve 33d in an open state to the place of use. Further, for example, the acidic water generated in the electrolysis chamber 14b on the positive electrode side is supplied to the place of use through the flow path switching valve 31 and the outflow pipe 33a and through the open outflow valve 33c.
[0024]
In the electrolyzed water generating apparatus, the flow state of the electrolyzed water is monitored by the flowing water sensors 26a and 26b interposed in the branch pipes 23b and 23c of the second water supply pipe 23 during the electrolysis operation, and An energization state of the electrolytic current is monitored by a current sensor 43 interposed in the middle of a connection circuit that connects the electromagnetic switch 42 of the power applying mechanism 40 and the electrode 13b.
[0025]
The control device 50 receives the water flow detection signals from the water flow sensors 26a and 26b, and stops the electrolysis operation when the water flow rate of the electrolyzed water calculated based on these water flow detection signals is equal to or less than the set flow rate. And enter a standby state. Further, the control device 50 receives a current detection signal of the electrolysis current from the current sensor 43, and controls the voltage applied to the electrodes 13a and 13b based on the current detection signal so that the electrolysis current becomes constant. When power is turned on by the main switch 51, the normal electrolysis operation is repeated in conjunction with the outflow valves 33c and 33d.
[0026]
Thus, in the electrolyzed water generating apparatus, when the power supply is stopped by the main switch 51, the control apparatus 50 operates to close the water supply control valve 27 and operates to open each discharge control valve 34c. Thereby, the water pressure from the supply source (water pipe 20a) side of the electrolyzed water (tap water) to the water supply mechanism 20, the electrolytic tank 10 and the outflow mechanism 30 is cut off, and the water supply mechanism 20, the electrolytic tank 10 and the outflow mechanism The pressure in the 30 flow paths is released and the pressure is reduced.
[0027]
Therefore, in the electrolyzed water generating apparatus, since the high water pressure resistance required for the electrolyzer 10, the water supply mechanism 20, the outflow mechanism 30 and the like is eliminated, these mechanisms do not require the use of highly durable parts. become.
[0028]
Further, in the electrolyzed water generating apparatus, the water supply control valve 27 can be disposed in the vicinity of the electrolyzer 10 or the operation panel, so that the main plug 24 provided near the electrolyzed water supply source 20a is used. The problem that the installation position is located far away from the installation location of the electrolyzed water generating device is solved.
[0029]
In the electrolyzed water generating apparatus, the open / close operation of the water supply control valve 27 is automatically performed by the control apparatus 50, and the water supply control valve 27 is closed in conjunction with the stop of the electrolysis operation. Even when it is forgotten to close the outflow valves 33c and 33d as the stop valves when the electrolysis operation is stopped, the leakage of water from the outflow pipes 33a and 33b can be eliminated or kept to a minimum. .
[0030]
In the electrolyzed water generating apparatus, by opening and closing the water supply control valve 27 and each discharge control valve 34c, the pressure in the apparatus can be greatly reduced, and the water is forcedly supplied and discharged in the apparatus. For the maintenance after the operation of the electrolyzed water generating device is stopped, for example, for the maintenance of the water quality in the device and the prevention of freezing, the water supply / discharge control for the water in the device is performed at regular intervals. It is possible.
