[0005]

In the electrolytic ionic water generating apparatus according to the present invention, a DC voltage is applied to both electrodes in both electrode chambers in a state where treated water such as water or saline solution flows in both electrode chambers of the electrolytic cell. Then, the treated water is electrolyzed in the electrolytic cell, and acidic ionic water is generated and discharged from the electrode chamber of the positive electrode, and alkaline ionic water is generated and discharged from the electrode chamber of the negative electrode.

First switching valve 35 and second switching valve 3
Numeral 6 denotes a rotary valve having a spherical valve element which is rotated by driving the first electric motor 37 and the second electric motor 38, respectively, as shown in FIGS. Disk cams 39 and 40 and disk cams 41 and 42 are integrally attached to the drive shafts 37a and 38a of the drive shaft 38, respectively.

It is configured so that the stop timings of 7, 38 can be detected.

The electric control device 50 is provided with a microcomputer, and has the above-described position detecting sensor 4.
3, 44 and the detection signals from the position detection sensors 45 and 46, a signal obtained by operating the generation operation switch SW1 for starting / stopping the ion water generation operation, and the cleaning switch SW2 for starting / stopping the pipe cleaning operation. Based on the signal obtained by the operation, the above-described electric supply pump 22, electrode switching means 51, power supply circuit 52,
The operation of the first electric motor 37 and the operation of the second electric motor 38 are controlled, and the following operations are obtained.

[Operation During Generation Operation] In the electrolytic ionic water generation apparatus configured as described above, when the generation operation switch SW1 is operated in the illustrated state and a start signal is output, the electric control unit 50 supplies electric power. The pump 22 is started to supply the treated water from the tank 20 to the electrode chambers 14 and 15 of the electrolytic cell 10, and the position detection sensors 43 and 44
For example, the electrode switching means 51 is de-energized on the basis of a signal from the power supply circuit 52, and an ON signal is output to the power supply circuit 52 so that the DC voltage between the positive electrode and the negative electrode of the power supply circuit 52 becomes a predetermined value. Therefore, the positive electrode of the power supply circuit 52 is connected to the electrode 11 of the electrolytic cell 10, and the negative electrode is connected to the electrode 12.
The acidic ionized water generated by the electrolysis in the inside and flowing from the electrode chamber 14 to the first discharge pipe 31 flows from the first discharge pipe 31 to the first discharge pipe 31.
The alkaline ionized water guided to the acidic ion water outlet pipe 33 via the switching valve 35 and flowing from the electrode chamber 15 to the second discharge pipe 32 is supplied from the second discharge pipe 32 to the second switching valve 36.
Is led to the alkaline ionized water outlet pipe 34.

When the elapsed time after the start of the generation operation (measured by a reverse rotation time setting timer (not shown) provided in the electric control device 50) reaches a set time (for example, 2 hours), the electric control device 50 An OFF signal is output to reduce the DC voltage between the positive and negative electrodes of the power supply circuit 52 to zero, and the electrode switching means 51 is turned on to connect the negative electrode of the power supply circuit 52 to the electrode 11 of the electrolytic cell 10; Also, the plus electrode is connected to the electrode 12, and both electric motors 37 and 38 are started. For this reason, the communication state of each switching valve 35, 36 is switched by each electric motor 37, 38, and the time when each switching is completed (each driving shaft 37a, 38).
at the time point a is rotated by 180 degrees).
Groove portions 41a, 42a or 41b, 42b engage with the position detection sensors 45, 46, and
When the stop timing of the power supply circuit 38 is detected, the electric control unit 50 stops the electric motors 37 and 38 based on the stop timing, and outputs an ON signal to the power supply circuit 52 to output a direct current between the positive electrode and the negative electrode of the power supply circuit 52. The voltage is set to a predetermined value. Therefore, in each of the electrode chambers 14 and 15 of the electrolytic cell 10, reverse ionized water is generated, and the electrode chambers 1 and 15 are generated.
The alkaline ionized water flowing from 4 to the first discharge pipe 31 is guided from the first discharge pipe 31 to the alkaline ionized water discharge pipe 34 via the first switching valve 35, while the acidic ionized water flowing from the electrode chamber 15 to the second discharge pipe 32. The ionic water is guided from the second discharge pipe 32 to the acidic ionic water outlet pipe 33 via the second switching valve 36. The elapsed time after the completion of the switching of each of the switching valves 35 and 36 is measured again by the reverse rotation time setting timer provided in the electric control device 50.

The reverse operation of the electrode switching means 51 and the two switching valves 35 and 36 is automatically performed at every set time unless the generation operation switch SW1 is stopped, whereby the respective electrodes 11 of the electrolytic cell 10 are turned off. , 12 are electrically backwashed, and before the reversal, the discharge pipe through which the alkaline ionized water flows is washed with the acidic ionized water flowing by the reversal. When the generation operation switch SW1 is stopped, a stop signal is output, and the electric control device 50 stops the electric supply pump 22 and outputs an OFF signal to the power supply circuit 52 to output the power supply circuit 52.
The DC voltage between the positive electrode and the negative electrode of the second electrode is made zero, and the electrode switching means 51 is turned off.

[Operation at the time of pipe cleaning] When the cleaning switch SW2 is operated during the above-described generation operation, a cleaning start signal is output from the electric control device 50, and the electric control device 50 determines that the electrode switching means 51 is not operated. If it is energized, it is energized; if it is energized, it is de-energized.
Therefore, in the electrolytic cell 10, ionic water is generated which is the reverse of that before the operation of the washing switch SW 2, and the alkaline ionic water flows from the discharge pipe through the switching valve to the acidic ionic water discharge pipe 33.
The acidic ionized water is guided from the discharge pipe to the alkaline ionized water outlet pipe 34 via the switching valve. For this reason, it is possible to dissolve and remove the precipitate deposited on the alkaline ionized water outlet pipe 34 to which the alkaline ionized water is supplied with the acidic ionized water during non-cleaning, and to perform the cleaning. Therefore, it is possible to save the trouble of replacing the alkaline ionized water outlet pipe, in which deposits such as calcium and sodium tend to accumulate. Further, since it is not necessary to circulate a chemical such as dilute hydrochloric acid to remove the precipitate, it is not necessary to prepare a pump and a tank dedicated to these chemicals. When the cleaning switch SW2 is stopped, the electric control device 50 outputs a cleaning end signal, and the electric control device 50 returns the electrode switching means 51 to the state before cleaning. During the above-mentioned washing of the pipes, the reverse ionic water is guided to the respective outlet pipes 33 and 34. Therefore, it is necessary to appropriately discard these ionic waters. A waste valve is provided near the outlet of each of the ion water outlet pipes 33 and 34. It is preferable that a waste pipe is provided to form a branch. If the disposal valve is also controlled by the control device 50, no inconvenience such as erroneous use of the ionic water to be disposed does not occur.

In the above embodiment, the electric control device 50
The electrode switching means 51 and both the switching valves 35 and 36 are switched at every set time during the generation operation, so that the acidic ion water is guided from the electrolytic cell 10 to the acidic ion water outlet pipe 33. Although the alkaline ionized water is introduced into the alkaline ionized water outlet pipe 34, a forward / reverse switch is provided in place of the above-mentioned timer, and the electrode switching means 51 and the two-way switching valve are provided each time the forward / reverse switch is operated during the generation operation. 35, 36
It is also possible to implement the present invention by configuring so that both can be switched.

In the above embodiment, only the electrode switching means 51 is switched by the electric control device 50 when the cleaning switch SW2 is operated.
When the cleaning switch SW2 is operated, both switching valves 3
Only 5 and 36 are switched, and the alkaline ionic water generated in the electrolytic cell 10 is guided from the discharge pipe to the acidic ionic water outlet pipe 33 via the switching valve during pipe washing, and the acidic ionic water is switched from the discharge pipe. It is also possible to carry out the present invention in such a manner that it is guided to the alkaline ionized water outlet pipe 34 via a valve. In the above-described embodiment, the pipe cleaning is performed between the time when the cleaning switch SW2 is started and the time when the cleaning switch SW2 is stopped. However, the electric control device 50 is provided with a cleaning timer for defining the pipe cleaning time. It is also possible to implement the present invention by configuring so that the pipe cleaning is performed only until the cleaning switch SW2 is activated and the cleaning timer times out.

In the above embodiment, the first discharge pipe 3
The first discharge pipe 31 and the second discharge pipe 3 are interposed at the connection portion between the first and second discharge pipes 32 and both ion water outlet pipes 33 and 34.
The first switching valve 35 and the second switching valve 36 are adopted as switching valve means for communicating the second and third components 2 with the acidic ionized water outlet pipe 33 or the alkaline ionized water outlet pipe 34, respectively. As shown in the figure, the first discharge pipe 31, the second discharge pipe 32, the acidic ionized water discharge pipe 3
3 and the alkaline ionized water outlet pipe 34 are connected to each other, and depending on the position of the rotating member 61, the ionized water is transferred from the first outlet pipe 31 and the second outlet pipe 32 to the acidic ionized water outlet pipe 33 or the alkaline ionized water outlet pipe 34. It is also possible to adopt a single motor-operated switching valve 60 capable of switching the flow path and to make the switching valve means compact.

The motor-operated switching valve 60 is the first embodiment of the present invention.
The switching valve 35 and the second switching valve 36 are driven by an electric motor similarly to the switching valve 35 and the pair of cam plates and a pair of position detection sensors so that the switching state and the stop timing of the electric motor can be detected.
The electric control device is controlled in the same manner as in the above embodiment. When the acidic ion water is supplied through the first discharge pipe 31 during the production operation and the alkaline ion water is supplied through the second discharge pipe 32, , Rotating member 6
1 is located as shown by the solid line, and when the alkaline ionized water is supplied through the first discharge pipe 31 and the acidic ionized water is supplied through the second discharge pipe 32, the rotating member 61 is rotated.
Is located as shown by the imaginary line, and the acidic ionized water outlet pipe 3
3 is supplied with acidic ionized water, and alkaline ionized water outlet pipe 34 is supplied with alkaline ionized water at all times.

In the above embodiment, the present invention is applied to an apparatus for electrolytically treating a saline solution. However, the present invention can be similarly applied to an apparatus for electrolytically treating fresh water. Further, in the above embodiment, the present invention was applied to the apparatus configured to supply the treated water stored in the tank 20 to the electrolytic cell 10 by the electric supply pump 22, but the treatment water was supplied from the water pipe through the electromagnetic water supply valve. The present invention can be similarly implemented in an apparatus configured to supply water to the electrolytic cell 10, in which case the electromagnetic water supply valve is connected to the electric control device 5.
