Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved electrolyzed water generator for continuously generating alkaline ionized water and acidic water.

[0002]

2. Description of the Related Art As a continuous electrolyzed water generator, a cathode membrane and an anode compartment are separated by a diaphragm through which metal ions can pass, and electrodes are provided in the respective pole compartments to apply a DC voltage to the cathode compartment. In addition, there is one that causes electrolysis and electropermeability of water flowing in the anode chamber. In this type of continuous electrolysis apparatus, it is known to control the application of the DC voltage to the electrodes of the electrolytic cell in accordance with the supply of water, so that the supply side before the electrolytic cell controls. That is,
When the supply of water is unnecessary, the valve on the supply side is closed and at the same time, the switch interlocking with the valve stops the application of the DC voltage to the electrode of the electrolytic cell.

In addition to this, there is one that performs a predetermined control by using the effluent discharged from the electrolytic cell. For example, in FIG.
In the apparatus of Japanese Utility Model Publication No. 63-7358, the water supply port side of the electrolytic cell is connected to a pressure water source such as tap water, and the pressure is used to secure the water pressure in the electrolytically generated water supply line. It is configured so that electrolyzed water can be taken out.

In FIG. 2, reference numeral 1 is an electrolytic cell, which is provided with a water supply chamber 2 at its lower end and is divided into a center and an outer peripheral side by a cylindrical porous diaphragm 3 at its upper part, and an outer peripheral side is a cathode chamber 4. The center of the anode chamber 5 is provided with electrodes 6 and 7, respectively. The bipolar chambers 4 and 5 communicate with the water supply chamber 2 at the lower ends. Further, the cathode chamber 4 and the anode chamber 5 are connected at their upper ends to the supply lines 8 and 9, respectively, and the supply line 8 is provided with a switch means 10 such as a flow switch. An opening / closing valve 11 such as a solenoid valve which is controlled to open / close by a signal from the means 10 is provided. A curran 12 is provided at the tip of the supply line 8 and can be manually opened and closed. In addition, the above-mentioned supply line 8
Has a three-way valve 13 that can be manually switched between the switch means 10 and the calan 12, and is switched and connected to the drain portion 14 of the supply line 9 so as to communicate the upstream side.

With such a structure, when the calan 12 is opened, electrolyzed water (alkali ionized water) in the supply line 8
Is squeezed out to the supply destination via the calan 12. At this time, the switch means 10 outputs a signal by the flow of water and opens the on-off valve 11. With this, electrolyzed water (acidic water) in the supply line 9
Is also discharged to the drain portion 14. A DC voltage is applied to the electrodes 6 and 7 by the function of the switch means 10. That is, when the alkaline ionized water flows from the cathode chamber 4 through the switch means 10, the on / off valve 11 which is interlocked by the signal generated at that time is driven to open, and the acidic water in the anode chamber 5 is discharged, The electrolysis state of the chamber 4 can reach the anode chamber 5. In this way, the water source and the respective supply lines 8 and 9 are connected to each other through the electrolytic cell to form a closed path, and the switch means 10 operates only when the calan 12 is opened to release the electrolytically generated water. Is done. According to the configuration of FIG. 2, by providing the switch means and the on-off valve, the electrolyzed water can be supplied to the target location in a pressure state using tap water pressure at a desired time.

[0006]

However, the conventional device of FIG. 2 has the following problems in practical use. In the apparatus of FIG. 2, not only the water pressure in the input side line of the electrolyzer changes depending on the usage status of tap water, but this electrolyzed water generating apparatus is not shown in FIG. It is assumed that the load on water will be constant, but in practice it will not always be used as assumed.

In FIG. 3 (a), the water discharged from the electrolyzer 1 is discharged from the calan 12 to a water release section 20 such as a sink in the upper portion thereof.
The configuration is such that the water is drained via the load pipe 21 that has been once started up toward. However, in this case, water is discharged under the water pressure corresponding to the resistance for the startup.

On the other hand, as shown in FIG. 3 (b), the ink may be discharged without receiving resistance. In the above example, the resistance based on the height of the sink was described, but it is rare that the drained water directly flows out from the calan 12, and in the actual use condition, it is used from the calan 12 via a hose such as resin. ing. At this time, an obstacle such as bending of the hose often occurs. As a result, the resistance of the wastewater changes depending on the discharge condition after the currant even if the water pressure input to the electrolyzed water generator is constant.

However, in the conventional apparatus of FIG. 2, the switch means 10 is a switch that responds to the flow rate, and therefore operates regardless of the above water pressure. Therefore, if only this is used for control, there are the following problems. (I) That is, with the signal from the switch means 10 only, a slight flow rate flow as a result of the increase in resistance due to the water pressure and a consciously reduced flow rate flow due to the result of squeezing the calan 12 are distinguished. The on-off valve cannot be controlled separately. Therefore, although not desired, there is a possibility that the electrolysis condition of the cathode chamber may reach the anode chamber. Therefore, alkaline ionized water having a pH outside the desired concentration is generated. (Ii) The switch means 10 outputs a signal even when there is only a small flow rate at the start of electrolysis. At this time, a DC voltage is immediately applied to the electrodes 6 and 7 regardless of the flow rate. For this reason, a large current may flow from the power source to the electrode, shortening the life of the electrode, and in some cases, the breaker of the power source may be activated to discontinue use.

An object of the present invention is to provide a continuous electrolyzed water generator which solves the above problems.

[0011]

In order to achieve the above object, the present invention divides an electrolytic cell to which a predetermined amount of water is supplied into a cathode chamber and an anode chamber with a diaphragm, and an electrode is provided in each electrode chamber, In a continuous electrolyzed water generator in which a DC voltage is applied to obtain alkaline ionized water and acidic water from the cathode chamber and the anode chamber, respectively, a flow switch that responds to the flow rate on the outlet side line that communicates with the negative or anode chamber side. Means, a pressure switch means for responding to water pressure in a line communicating with the inlet side of the electrolytic cell, and a valve for an outlet side line communicating with the positive or negative electrode chamber side, respectively, for responding to signals generated by the flow switch means and the pressure switch means. The gist is that it is configured to control the above valve.

In the above apparatus of the present invention, power switch means for controlling the application of the DC voltage to the electrodes in response to the signals from the flow switch means and the pressure switch means may be provided.

[0013]

The valve is opened by a signal from each of the pressure switch means and the flow switch means when they are activated. If the power switch means is provided,
At this time, it is turned on to start electrolysis, and acidic water and alkaline ionized water having a predetermined pH concentration are obtained.

[0014]

Embodiments of the present invention shown in the drawings will be described below.
FIG. 1A shows an embodiment of a continuous electrolyzed water producing apparatus according to the present invention, and the same reference numerals as those in FIG. 2 represent the same or similar parts. The structure of the electrolytic cell 1 is shown in FIG.

The embodiment of FIG. 1 differs from the conventional apparatus of FIG. 2 in that the inlet side line 15 for supplying water to the electrolytic cell 1 is different.
A pressure switch 16 that responds to water pressure is provided in the control circuit 17, and the control circuit 17 controls the valve 11 to open in response to signals generated by the pressure switch 16 and the flow switch 10. Further, in the above embodiment, it is preferable that the control circuit 17 responds to signals from the pressure switch 16 and the flow switch 10 by the power switch 1.
8 is turned on.

With such a structure, when a predetermined water, for example, tap water is supplied and the calan 12 is opened, signals are output from the pressure switch 16 and the flow switch 10,
In response to this, the power switch 18 is turned on, a DC voltage is applied to the electrodes 6 and 7, electrolysis is started, and the valve 11 is opened. Therefore, the alkaline ionized water and the acidic water flow through the supply lines 8 and 9, and are pressure-fed to the supply destination via the currant 12 and the valve 11.

A polarity switching circuit 19 for the DC voltage applied to the electrodes may be provided in the embodiment of FIG.
As the polarity switching circuit 19, for example, a switch as shown in FIG. 1C is used, and the switching is controlled by the control circuit 17. If the polarity switching circuit 19 is inverted by the control circuit 17, for example, a positive voltage can be applied to the cathode 6 and a negative voltage can be applied to the anode 7. Therefore, by this, not only the flow rate of the anode water can be controlled by the flow rate of the cathode water, but conversely, the flow rate of the cathode water can be controlled by the flow rate of the anode water. In the above embodiment, the control circuit 17 is linked with the polarity switching circuit 19 if necessary.
The three-way valve 13 can also be controlled by. Thereby, the flow switch 10 can be easily pickled.

[0018]

As described above, according to the present invention, the valve on the outlet side of the anode chamber is opened in response to not only the signal from the flow switch on the outlet side of the electrolytic cell but also the signal from the pressure switch on the inlet side. As a result, the electrolyzed water having the desired pH is output regardless of the inflow pressure of the electrolytic cell and the water flow resistance after the currant. If the power switch is turned on by the signals from the above two switches, a DC voltage will not be applied to the electrodes when the flow rate in the electrolytic cell is low, so a large current will not flow at the start of electrolysis. .
