The reverse voltage cleaning is performed by reversing the voltage applied to the electrode while the electrolytic cell is filled with water.

In order to achieve the first object, an electrolytic ionized water generator according to the present invention comprises: a continuous flow-through type electrolytic cell having a water supply pipe and a drain pipe at its lower part; A switch means for detecting the passage of water and performing an on / off operation; responding to an on / off signal of the switch, applying a DC voltage having a predetermined polarity for generating electrolytic ionic water to the electrode of the electrolytic cell with one of the signals; The reverse of the polarity of the DC voltage is switched by the other signal of the switch means to switch to power supply for backwashing, and the power supply for backwashing is stopped by a signal from the stop signal means for backwashing power supply. A control mechanism; at least while the DC voltage of the predetermined polarity or the reverse polarity is being applied to the electrode of the electrolytic cell, the drainage line is closed, and after the application of the reverse polarity voltage of the reverse cleaning is stopped, the drainage tube is stopped.

6 has an electrolysis control circuit 11 for closing the normally closed contact 17 of the reverse power circuit 14 for a set time, whereby the switch means 8
For example, when the switch is on, a predetermined polarity DC voltage for generating electrolytic ionic water is applied to the electrodes 5 and 6, and when the switch means 8 is turned off, the polarity is reversed for a set time of the reverse voltage timer circuit 16 to perform reverse voltage cleaning. Is supplied, and after the backwashing for a certain period of time, the backfeeding of the backwashing is stopped.

[0027] In such conductive Machinery path, in the embodiment of FIG. 9, a pair of parallel branch circuit 15a, the electric valve circuit 15 with 15b, provided with in parallel to the electrolysis control circuit 11, the pair of parallel branch circuits One of 15a and 15b is provided with a normally closed contact 18a of the electrolysis circuit 13 and the other branch circuit 15b is provided with a normally closed contact 18b of the reverse power circuit 14. Then, the electric valve circuit 15 closes the electric valve 10a of the drainage pipe 9 by an output signal when either of the contacts 18a, 18b is turned on, and the electric valve 10a by the output signal when both are off. It is configured to open.

Thus, in the embodiment shown in FIG. 9, the drain line 9 is applied to the electrodes 5 and 6 of the electrolytic cell 1 while the DC voltage having the predetermined polarity for generating the electrolytic ionic water or the reverse polarity for the reverse electric cleaning is applied.
Is closed, and the drain line 9 is opened only when no voltage is applied to any of the electrodes.

On the other hand, in the electric circuit shown in FIG. 10, a timer circuit 19 and a motor-operated valve circuit 15 are provided in parallel with the reverse power circuit 14, and the normal time of the reverse power timer circuit 16 is provided between the reverse power circuit 14 and the timer circuit 19. An open contact 20 is provided, and a normally closed contact 21 of a timer circuit 19 is provided in the electric valve circuit 15. When the reverse power timer circuit 16 reaches the reverse power set time, the reverse power circuit 14 is turned off, and at the same time, the electric valve circuit 15 is turned on for the set time of the timer circuit 19, and the output signal opens the electric valve 10a.

When the electric valve circuit 15 is turned off after the set time, the electric valve 10a is closed. When the switch 12 is connected to the electrolytic circuit 13, the electric valve circuit 15 is turned off by the switch 12, so that the electric valve 10a is closed.

Thus, in the embodiment of FIG. 10, the drainage line 9 is closed until the backwashing is completed after the generation of the electrolytic ionic water, and after the backwashing, the drainage line 9 is opened for a set time of the timer circuit 19. . Therefore, by adjusting the set time of the timer circuit 19 to the time required for drainage and drainage, the drainage pipe 9 can be opened for the time required for drainage of residual water.

A motor-operated valve controlled by electric control opens and closes a check valve by means of a solenoid as shown in FIG. 1, and a line 9 which is directly driven by a solenoid valve as shown in FIG.
, A motor valve as shown in FIG. 4 or a ball valve having a passage as shown in FIG. FIG. 8 shows a diaphragm mounting structure with less fatigue.

In the above embodiment, the drain pipe 9 is opened only by the electric valve 10a. However, the present invention is not limited to this, and as shown in FIG. A check valve 21 may be added to the drain pipe 9.
In this configuration, since the electric valve is controlled in a state where no water pressure is applied, there is an advantage that the operating force can be reduced and the operating performance is improved.

FIGS. 6 and 7 show schematic diagrams of an electrolytic ionized water generator for opening and closing the drainage line 9 by mechanical valve control means. FIGS. 13 and 14 show the electrolytic control used in this device. FIG. 3 shows a circuit diagram.

The valve control means of the embodiment shown in FIGS. 6 and 7 comprises a check valve 10b installed in the drain pipe 9 and a damper 23 provided with a piston rod 22 for opening and closing the check valve 10b. The damper 23 arranges the tip of the piston rod 22 which reciprocates at a predetermined stroke in the opening direction of the check valve 10b, and pushes the rod 22 to the shaft of the rod 22 by the water pressure of the water supply pipe 2. 24, and this operating member 24 is connected to a cylindrical support member 25 communicating with the water supply pipe 2.
Is reciprocally fitted.

Inside the casing 27 of the damper 23, the operating member 24 of the rod 22 receives the water pressure of the water supply pipe 2 and easily pushes the piston rod 22 back to the shortened position. Thus, the speed in the valve opening direction is adjusted so that the tip reaches the open position of the check valve 10b over a predetermined time, that is, the backwash time, and the check valve 10b is opened after the backwash time elapses. .

Thus, in the embodiment of FIGS. 6 and 7, the damper 23 is pushed back during electrolysis of a predetermined polarity, and the drainage line 9 is closed by the check valve 10b. When the supply of water is stopped, backwashing is started. However, since a predetermined time is required until the tip of the piston rod 22 of the damper 23 reaches the open position of the check valve 10b, the check valve 10b is operated during this time. Reverse electricity cleaning is performed with the lid closed.

In the embodiment of FIG. 6, the diaphragm 8a of the switch means 8 and the rod operating member 24 of the damper 23 are integrally connected, whereby the switch means 8 and the damper 23 are combined in a complex manner. In this embodiment, only the switch portion 8b of the switch means 8 is provided behind the damper 23, and the switch is turned on and off by an operating piece 29 which is interlocked with the diaphragm 8a of the switch means 8. However, the present invention is not limited to the above configuration, and the damper 23 and the switch unit 8 can be separately provided.

When the valve control means is constituted by the check valve 10b and the damper 23 as described above, a switch as shown in FIG. 6 and FIG. It is desirable that the means 8 be divided into a switch 8b for detecting water flow and a switch 8c for stopping water supply, and the skewer switches 8b and 8c be provided separated from each other in the axial direction of the piston rod 22 of the damper 23.

The check valve 10b of the drain line 9
As shown in FIG. 7, the drain line 9 is diverted from the water supply pipe 2 in an inverted U-turn so that the check valve 10b is closed by the water supply pressure. Is more preferred.

In the above description, the case of using the reverse power timer as the means for stopping the power supply for the reverse power cleaning, that is, the means for turning off the reverse power circuit 14 shown in the figure, but the present invention is limited to this. Instead, for example, the following various sensors can be used. (A) An electric capacity sensor that detects the integrated electric capacity of the backwashing power supply and outputs a signal. (B) A current sensor that detects a change in current during backwashing power supply and outputs a signal. (C) Backwashing. Conductivity sensor that detects a change in the conductivity of water in the electrolytic cell during power supply and outputs a signal. (D) Temperature sensor that detects a change in the temperature of water in the electrolytic cell during power backup and supplies a signal. ) A pH sensor that detects a change in the pH of the water in the electrolytic cell during the backwashing power supply and outputs a signal. The above sensors (b), (c), (d), and (e) correspond to the backwashing power supply. As a change over time, a point at which the current or conductivity flowing through the electrolyzed water changes, or a point at which the temperature or the pH value of the electrolyzed water changes, is used to output each change as an electric signal. Then, according to the output signal of the sensor, the reverse power circuit 14 in the electric circuit diagram is opened to stop the power supply.

If the switch means 8 for switching between the positive electrolysis and the reverse electrolysis cleaning electrolysis is divided into a water flow detection switch 8b and a water supply stop detection switch 8c, the water flow detection switch 8b A positive signal voltage is applied to the electrode of the electrolytic cell by a control signal (for example, an ON signal), and even when the water supply stop detection switch 8c is turned on, the positive application voltage is maintained and the water supply stop detection is performed. Switch 8c
When is turned off, the polarity of the applied voltage is switched to supply power for backwashing.
When b becomes OFF, the reverse cleaning power supply may be stopped (refer to claim 8).

In the above embodiment, the case where the electrolysis of a predetermined polarity, ie, the generation of the electrolytic ionic water is stopped, and the backwashing and the drainage of the residual water are performed every time, is described.
Electrolysis of a predetermined polarity may be performed several times, and when a predetermined electrolysis integrated value is reached, back electrolysis cleaning and drainage of residual water may be performed. For this reason, in the embodiment of FIG. 11, FIG. 12, and FIG.
When the integrating circuit 30 reaches a predetermined integrated value, the reverse power circuit 14
Are provided.
In the embodiment of FIG. 12, the relay valve 32 that turns off the electric valve circuit 15 when the integration circuit 30 reaches the integrated value is necessary because the electric valve circuit 15 must be kept in a non-conductive state until the integrated value is reached. Is provided.

When switching from the predetermined polarity to the reverse polarity is performed instantaneously, a spark occurs. To prevent this,
It is desirable to temporarily stop the voltage application and then switch to the reverse voltage application. This object is achieved, for example, 11, 12, so that the timer 3 in the electric circuit during reverse voltage in FIG. 14
3 and a relay contact 34 for turning off the reverse power circuit 14 by the timer 33 for a predetermined short time.

Further, when reverse voltage is applied, the electrolytic cell 1 is easily heated, so that a trouble is likely to occur when a normal voltage is applied for a long time. For this reason, at the time of reverse power, it is desirable to lower the voltage by, for example, half-wave rectification or other means. FIG. 15 exemplifies a circuit in which the applied current is half-wave rectified at the time of reverse voltage.

[0045]

According to the present invention, when performing the backwashing after the electrolytic ionic water is generated, the remaining water is not drained during the backwashing.
Drainage is started after the reverse power supply stops. Therefore,
Since the power supply for the backwashing is always performed in a state where the electrolytic bath is filled with water, the backwashing operation and the cleaning effect are remarkably improved over the entire area of the electrolytic bath during a predetermined time.

Further, since a drain pipe for draining residual water after washing is provided in the lower part of the electrolytic tank separately from the electrolytic water discharge pipe, there is a possibility that washing sewage is mixed into potable electrolytic water or the like. It is surely eliminated.

Since the power supply to the electrodes is temporarily stopped when the polarity of the reverse voltage is reversed, sparks at the time of switch switching are prevented.

By lowering the applied voltage during the backwash, the heating of the electrolytic cell is prevented, so that the backwash can be continued for a long time. As a result, the acidification of the cathode compartment dissolves not only the electrodes but also the calcium on the surface of the electrolytic membrane, and the cleaning effect is further improved. Further, according to the present invention, the backwashing is performed in a state where the electrolyzer is filled with water, and the voltage of the electrolyzer is sterilized by lowering the voltage applied during the backwashing (for example, 50 ° C.). (Before and after) and the reverse voltage duration required for sterilization (for example, several minutes to several tens of minutes), so that the effect of two birds per stone that the electrolytic cell is sufficiently sterilized during the reverse power cleaning can be obtained.
