DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved electrolytic ionized water generator. More specifically, the reverse of cleaning the electrolytic cell
The present invention relates to the maintenance of the water level in an electrolytic cell for electrolysis.

[0002]

2. Description of the Related Art In a continuous electrolytic ionized water generator, calcium oxide, magnesium carbonate, calcium hydroxide, magnesium hydroxide, etc. precipitate on a cathode plate when electrolysis is performed for a predetermined time or more, as is well known. Adhere to. Therefore, in order to remove these deposits, the polarity of the voltage applied to the anode plate is periodically inverted for a predetermined time to dissolve the deposits.

[0003] Thus, the polarity inversion operation is performed at the time of electrolysis, there is a possibility that drinking accidentally unsuitable acidic water drinking is generated to the cathode chamber, using residual water in the electrolytic cell during electrolysis is stopped It is desirable to do it. In this case, if an automatic drain valve is provided in the electrolytic cell for discharging residual water, the water level in the electrolytic cell may be insufficient and may not reach the upper part of the electrode plate depending on the structure. Since the polarity inversion time becomes relatively short to some extent if the water level is above the electrode plate, the deposits on the cathode plate may not be sufficiently dissolved and removed.

[0004]

Therefore, conventionally, a solenoid valve or a motor-operated valve is used as the automatic drain valve, and the valve operation is delayed by being driven through a timer circuit or a delay circuit, so that a sufficient polarity inversion time is obtained. To maintain the required water level during However, according to such a conventional method, there is a drawback that the cost is high and the configuration is complicated, and complete drainage is not possible depending on the valve structure, which also leads to decay of residual water.

It is an object of the present invention to provide an electrolytic ionized water generator having a simple and inexpensive delay drain valve by solving the above-mentioned conventional disadvantages.

[0006]

According to the present invention, a cathode plate and an anode plate are disposed in an electrolytic cell with a separator interposed therebetween so as to continuously flow water. Along with
An acidic ionic water generator configured to invert the polarity of the voltage applied to the cathode plate and the anode plate when the electrolysis is stopped and the drainage channel communicates with the acid drainage port for a predetermined period of time, and When the level of the residual water in the electrolytic cell is maintained at a predetermined level during the polarity reversal time when the electrolysis is stopped, and operated to drain the residual water after the lapse of the time , a delay drain valve is provided for the electrolytic cell. The delay drain valve is provided in a bypass channel communicating from the water supply channel to the drain channel.
Spring force and sliding friction between sliding part and piston
The gist is that a delay time is set by braking by friction .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below.
FIG. 1 shows an embodiment of the electrolytic ionized water generator of the present invention, wherein 1 is an electrolytic cell, 2 is a separator, 3 is a cathode plate, 4 is an anode plate, 5 is a delay drain valve, and 5i is a slide of the delay drain valve. Moving part, 6 is a flow sensor,
7 is a water pressure switch, 8 is a water outlet, 9 is a damper, 10 is a drain port, and 11 is a tap.

In FIG. 1, normally, water is continuously supplied from a tap faucet 11 into an electrolytic cell 1 via a water supply channel 1a, and a negative voltage and a positive voltage are applied to a cathode plate 3 and an anode plate 4, respectively. ,
Electrolysis is performed, alkaline ionized water is obtained from the water discharge port 8 through the damper 9, and acidic water is discharged from the water discharge port 10. The drain 10 communicates with the drain. Then ,
In order to remove the deposit from the electrode plate, the supply of water from the faucet 11 was stopped, and the polarity of the voltage applied to the cathode plate 3 and the anode plate 4 was reversed. A voltage and a negative voltage (−) are applied to the anode. In this case, the delayed drain valve 5 opens after a predetermined time delay and starts draining. Therefore, if this delay time is set to a value which is appropriately longer than the required polarity inversion time, the water level in the electrolytic cell 1 is set to a sufficient water level a corresponding to the head pressure during this polarity inversion time. And after that time drains automatically. The water level indicated as the water level b is the water level at the upper end of the electrode, and the water level a is desirably at least at a height position equal to or higher than the water level b.

FIG. 2 shows an example of the configuration of the delay drain valve 5. 5a is a piston, 5b is a sliding rubber packing, 5c is a valve body push-up spring, 5d is a cylinder, 5e is a rod, 5f is a support plate, and 5g is a cylinder. An inlet opening 5h is a cylinder outlet opening, and 5i is a sliding portion of the sliding rubber packing 5b. The delay drain valve 5 is disposed in a bypass passage 1c communicating from the water supply passage 1a to the drain passage 1b of the electrolytic cell 1, and is provided to the piston 5a to which water pressure is applied via a sliding rubber packing 5b and a support plate 5f. The structure is such that the force of the body push-up spring 5c is applied. When the electrolysis is stopped and the polarity is reversed, the tap water pressure disappears , and only the head pressure of the residual water shown by hatching in FIG. 1 is applied to the piston 5a, but the force of the valve body push-up spring 5c is increased with respect to this head pressure. Piston 5a to overcome
Is pushed out to the water supply channel 1a side, and becomes a state of FIG. 3A, that is, a state in which the piston 5a and the sliding portion 5i protrude to the water supply channel 1a side. As a result, as shown by the arrow, the residual water passes through the gap between the sliding portion 51 and the support plate 5f, the gap between the edge surface of the support plate 5f and the cylinder 5d, and from the space between the valve body push-up spring 5c and the cylinder. The water is discharged to the drain 1a through the outlet opening 5h. While the sliding portion 5i is sliding with the piston 5a, braking by the frictional force of the sliding portion 5i of the rubber packing 5b works to gradually move the piston 5a, so that a necessary delay time can be taken. In the state of FIG. 3A, the delayed discharge valve 5 is opened,
The residual water in the electrolytic cell 1 is discharged. When the electrolysis is performed, the tap water pressure is added, so that the biston 5a is pushed back. Further, since the sliding portion 5i and the cylinder 5d are tightly fixed , the state shown in FIG.

The dotted line in FIG. 4 shows the change in the pH of the discharged water with respect to the flow rate (vertical axis) according to the conventional example without reverse electrolysis, and the solid line shows the change in the pH of the discharged water of the present invention. As is clear from the figure,
In the conventional example, the electrolysis efficiency is reduced due to the adhesion of calcium or the like, but according to the present invention, the reduction in the electrolysis efficiency is very low. Further, FIG. 5 shows the temporal change of the pH value of the cathode remaining water, for example, the delay time of the delay drain valve of the present invention Taking about 30 seconds, it can be seen that a practically sufficient.

[0012]

According to the present invention as described above, according to the present invention, the slave
Replaced with automatic drain valves such as solenoid valves and electric valves
Drainage of residual water in the electrolytic cell by friction between the piston and the sliding part.
By installing a simple and inexpensive delay drain valve that brakes by force in the bypass channel that communicates from the water supply channel to the drain channel of the electrolytic cell, the level of the residual water in the electrolytic cell is maintained at a predetermined level, and the required polarity is maintained. Since the drainage can be performed after the reversal time is maintained, the deposits on the electrode plate can be reliably removed.
