Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous water flow type electrolytic ion water generator for electrolyzing tap water or the like to prepare alkaline ionized water and acidic water.

[0002]

2. Description of the Related Art As is well known, a continuous water-flow type electrolytic ionized water generator electrolyzes water supplied from one side of an electrolysis cell while passing it through an electrode chamber of the electrolysis cell, and alkali water is supplied from the other side of the electrolysis cell. It is configured to produce water and acid water separately.
During use of this type of device, deposits such as calcium adhere to the cathode chamber and other passages of alkaline water, resulting in a decrease in electrolysis capacity.

In order to solve this problem, the actual fairness 2-76
As shown in Japanese Patent Publication No. 75, there is one in which the polarity of the applied voltage is reversed at the same time when the water supply to the electrolytic cell is stopped, and the reverse electrolysis cleaning is performed until the residual water in the electrolytic cell is drained.

[0004]

However, in the above-mentioned one, since the reverse electrolysis cleaning operation is performed while draining the residual water in the electrolytic cell, the water is drained during the reverse electrolysis cleaning, and the reverse electrolysis cleaning of the part is not performed. Disabled Particularly, in a continuous water-flow type electrolytic ionized water generator that supplies water from the lower part of the electrolytic cell and flows out the electrolytic water from the upper part, a large amount of calcium tends to adhere to the upper electrode and the electrolytic diaphragm where the alkali ion concentration is increased. When attempting to drain residual water from the lower part of the electrolytic cell in such an apparatus, there arises an inconvenience that the portion having the most adhering substances is not washed most.

In the case of the type in which residual water is drained from the electrolytic water discharge passage in the upper part of the electrolytic cell while continuing to supply water to the electrolytic cell, the electrolytic water faucet and the cleaning water outlet are common, so that the reverse electrolytic cleaning water is There is another problem of using it for drinking.

Therefore, an object of the present invention is to carry out reverse electrolysis cleaning in a state where the electrolytic cell is always filled with water, and after completion of the reverse electrolysis cleaning, the cleaning water is drained from the dedicated drainage line under the electrolysis cell. An object of the present invention is to provide an electrolytic ionized water producing device.

[0007]

In order to achieve the above object, the electrolytic ionized water producing apparatus of the present invention is a continuous water flow type electrolytic cell having a water supply pipe line and a drainage pipe line at the bottom thereof; Switch means for turning on and off by detecting water flow to the cell; and in response to an on / off signal of the switch, a DC voltage of a predetermined polarity for generating electrolytic ionized water to the electrode of the electrolytic cell by one signal Is applied, and the polarity of the DC voltage is inverted by the other signal of the switch means to switch to power supply for backwashing, and power supply for backwashing is supplied by a signal from the stop signal means for backwashing power supply. And an electrolysis control mechanism for stopping; at least while the DC voltage of the predetermined polarity or the reversal polarity is being applied to the electrodes of the electrolytic cell, the drainage conduit is closed, and after the voltage application of the reversal polarity of the reverse electric cleaning is stopped, Open the drainage line and Valve control means for performing reverse electrolysis cleaning in a state where the electrolysis cell is filled with water, and for discharging water in the electrolysis cell from the drain pipe after completion of the electrolysis cleaning. Characterize.

The control of the valve means for opening and closing the drainage pipe is performed by a mechanical control means for controlling the check valve with a damper operated by the water pressure of the water supply pipe and an electric control for controlling the electric valve by the output signal of the electrolytic control circuit. There is an intelligent control means.

The reversal of the voltage polarity for back washing may be activated every time electrolytic water is generated, that is, every time the water flow detecting switch means is turned off, and electrolytic ion water is generated. Alternatively, the electrolysis may be activated when the electrolysis having a predetermined polarity reaches a predetermined integrated value and the water flow detection switch means is turned off.

Power supply may be stopped for a moment immediately before reversing the polarity of the applied voltage, and the polarity may be reversed in a state where no voltage is applied to the electrodes.

In another embodiment, a reverse polarity voltage for reverse electrolysis cleaning is automatically lowered by half-wave rectification with respect to an applied voltage of a predetermined polarity.

[0012]

When water is supplied to the electrolytic cell, the water flow detecting switch means is activated, and a DC voltage of a predetermined polarity is applied to the electrode of the electrolytic cell by the output signal thereof to generate electrolytic ionic water. During this time, the opening / closing valve of the drainage pipe is closed.
When the water supply is stopped and the water flow detecting means is turned off, the voltage polarity is reversed and the back electrolysis cleaning is performed for a certain period of time, but the opening / closing valve of the water draining pipe is also closed during this time. After a certain amount of back electrolysis cleaning time has elapsed, the opening / closing valve of the drainage pipe opens and the residual water starts to be discharged.

Thus, it is guaranteed that the reverse electrolysis cleaning is always performed while the electrolytic cell is filled with water, and the residual water is drained after the reverse electrolysis cleaning.

According to the inventions of claims 1 to 11, in the electrolyzed water generating operation, reverse electrolysis cleaning and residual water drainage are carried out every time the supply of water is stopped, whereas in the invention of claim 12 the electrolysis is carried out to a predetermined integrated value. On the condition that the water supply has been reached, the polarity of the applied voltage is reversed when the water supply is stopped, and the reverse electrowashing is performed.

[0015]

A drain pipe 9 for discharging residual water in the electrolytic cell 1 is connected to the lower portion of the electrolytic cell 1. In the illustrated embodiment, the drainage pipe 9 is configured by a branch pipe branching from the water supply pipe, but the present invention is not limited to this. For example, although not shown, the water drainage pipe 9 is supplied with water. It is also possible to have a configuration that is completely independent of the tube 2.

An opening / closing valve 10 whose opening / closing is controlled by a valve control means which will be described later is installed in the water draining pipe 9.

The switch means 8 detects the flow of water from the water supply pipe 2 to the electrolytic cell 1 and stops the flow of water, and transmits respective detection signals. In the embodiment of FIGS. 1 to 5, the switch means 8 is operated by the water supply pressure. A diaphragm 8a and a reed switch that outputs an ON / OFF signal by the operation of the diaphragm 8a,
Switches 8b such as limit switches and micro switches
It consists of

Thus, when water is supplied to the electrolytic cell 1, the detection signal (ON signal) of the switch means 8 causes the electrolytic cell 1 to be supplied.
When a DC voltage having a predetermined polarity for generating electrolytic ionized water is applied to the electrodes 5 and 6 on the other hand, while the water supply to the electrolytic cell 1 is stopped, the switch means 8 detects this and the detection signal at that time is detected. (OFF signal) reverses the polarity of the applied voltage,
Reverse electrolysis cleaning is performed in the electrolytic cell 1 until the application of the polarity reversal voltage to the electrodes 5 and 6 is stopped.

The opening / closing valve 10 of the water drainage conduit 9 is inverted at least while the DC voltage of the predetermined polarity is applied to the electrodes 5 and 6 of the electrolytic cell 1 (that is, when electrolytic water is being generated). There is provided valve control means for closing the drainage pipe 9 while the DC voltage of the polarity is being applied (that is, during reverse electrolysis cleaning), and opening the drainage pipe 9 after stopping the application of the voltage of the polarity reversal. There is.

The valve means includes electrical control for opening / closing the valve 10 according to the output signal of the electrolytic control circuit, and mechanical control means for opening / closing the valve 10 by a damper operated by the water pressure of the water supply pipe.

1 to 5 are schematic block diagrams of an electrolytic ion generator for controlling the opening and closing of the water drainage pipe 9 by means of an electrical valve control means, and FIGS. 9 to 13 are electrical control circuit diagrams thereof.

In the above electric control circuit, the electrolytic circuit 1
Reference numeral 3 is a control circuit for applying a direct current voltage having a predetermined polarity to the electrodes 5, 6 to generate electrolytic ion water, and 14 is a control circuit for inverting the polarity of the voltage applied to the electrodes 5, 6 for reverse electrolysis cleaning. , 15 are electric valve circuits for controlling opening and closing of the electric valve 10a installed in the drainage pipe 9. In the circuits of FIGS. 9 and 10, the electrolytic circuit 13 is switched to the reverse circuit 14 by the switch 12 of the switch means 8 of the water supply pipe 2, and only the set time of the reverse timer circuit 16 provided in parallel with the reverse circuit 14 is set. An electrolytic control circuit 11 for closing the normally closed contact 17 of the reverse electric circuit 14 is provided, whereby a DC voltage of a predetermined polarity for generating electrolytic ionized water is applied to the electrodes 5, 6 when the switch means 8 is on, for example. Switch means 8
Is turned off, the polarity is reversed for the set time of the reverse charge timer circuit 16 to supply power for reverse charge cleaning, and the power supply for reverse charge cleaning is stopped after the constant time reverse charge cleaning. ing.

In such an electric control circuit, in the embodiment of FIG. 9, an electric valve circuit 15 having a pair of parallel branch circuits 15a and 15b is provided in parallel with the electrolysis control circuit 11 and the pair of parallel branch circuits 15a. , 15b
On one side, 15a is provided with the normally closed contact 18a of the electrolytic circuit 13, and on the other branch circuit 15b is provided with the normally closed contact 18b of the reverse electric circuit 14. And the electric valve circuit 15
Is configured such that if either of the contacts 18a, 18b is on, the output signal thereof closes the electric valve 10a of the water drain pipe 9, and when both are off, the output signal opens the electric valve 10a. There is.

Thus, in the embodiment shown in FIG. 9, the drainage line 9 is provided while the predetermined polarity of electrolytic ion water production or the reverse polarity DC voltage of reverse electrolysis cleaning is applied to the electrodes 5 and 6 of the electrolytic cell 1.
Is closed and the drainage line 9 is opened only when no voltage is applied to any of the electrodes.

On the other hand, in the electric circuit of FIG. 10, a timer circuit 19 and an electric valve circuit 15 are provided in parallel with the reverse electric circuit 14, and the reverse electric timer circuit 16 normally operates between the reverse electric circuit 14 and the timer circuit 19. An open contact 20 is provided and a normally closed contact 21 of the timer circuit 19 is provided in the electric valve circuit 15. When the reverse charge timer circuit 16 reaches the reverse charge set time, the reverse charge 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. Circuit 19
After the set time, the electric valve circuit 15 is turned off and 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 the electric valve 10a is closed.

Thus, in the embodiment shown in FIG. 10, the drainage pipe 9 is closed from the generation of electrolytic ion water to the completion of the reverse washing, and after the reverse washing, the draining pipe 9 is opened for the set time of the timer circuit 19. .. Therefore, by adjusting the set time of the timer circuit 19 to the time required for draining and draining, it is possible to open the drainage conduit 9 only for the time required for draining residual water.

An electric valve controlled by electric control is a solenoid valve that opens and closes a check valve as shown in FIG. 1, and a solenoid valve as shown in FIG.
And those that use a motor valve as shown in FIG. 4, or those that electrically open and close a ball valve having a passage as shown in FIG. 5, and any other known element. Further, 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. As illustrated in FIG. 3, the water on the upstream side of the electric valve 10a is not limited to this. A check valve 21 may be added to the drain pipe 9.
With 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 is small and the operating performance is improved.

FIG. 6 and FIG. 7 are schematic block diagrams of an electrolytic ionized water generator for opening and closing the water draining pipe 9 by means of mechanical valve control means, and FIGS. 13 and 14 are electrolytic control for use in this device. The circuit diagram is shown.

The valve control means of the embodiment shown in FIGS. 6 and 7 is composed of a check valve 10b installed in the drainage pipe 9 and a damper 23 having a piston rod 22 for opening and closing the check valve 10b. The damper 23 arranges the tip of a piston rod 22 which reciprocates with a predetermined stroke in the opening direction of the check valve 10b, and pushes the rod 22 back to the shaft of the rod 22 by the water pressure of the water supply pipe 2. A cylindrical support member 25 that fixes 24 and connects the operating member 24 to the water supply pipe 2.
It is fitted so that it can reciprocate freely.

Inside the casing 27 of the damper 23, the actuating 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. The speed in the valve opening direction is adjusted so that the tip reaches the check valve 10b over a predetermined time by force, that is, the reverse electrolysis cleaning time, and the check valve 10b is opened after the reverse electrolysis cleaning time has elapsed.

Thus, in the embodiment of FIGS. 6 and 7, the damper 23 is pushed back during the electrolysis of the predetermined polarity, and the drainage pipe 9 is closed by the check valve 10b. Reverse water cleaning is started when the water supply is stopped, but since it takes a predetermined time for the tip of the piston rod 22 of the damper 23 to reach the check valve 10b, the check valve 10b remains closed during this period. Reverse electrolysis cleaning is performed.

In the embodiment of FIG. 6, the diaphragm 8a of the switch means 8 and the rod actuating member 24 of the damper 23 are integrally connected, whereby the switch means 8 and the damper 23 are combined in a complex manner, and the embodiment of FIG. Then, in addition to the combination as described above, only the switch portion 8b of the switch means 8 is provided at the rear of the damper 23 so that the switch is turned on and off by the operating piece 29 which is interlocked with the diaphragm 8a of the switch means 8. However, the configuration is not limited to the above, and it is of course possible to install the damper 23 and the switch means 8 separately.

As described above, when the valve control means is composed of the check valve 9 and the damper 23, in order to quickly control the opening and closing of the valve in response to water supply and stop of water supply, FIG.
As shown in FIG. 7, the switch means 8 is a switch 8 for detecting water flow.
b and the water supply stop switch 8c are separately configured, and the knuckle switches 8b and 8c are provided on the piston rod 22 of the ramp 23.
It is desirable that they be provided separately from each other in the axial direction.

The check valve 10b of the drainage pipe 9
In order to prevent the water from being opened by the water supply pressure, as shown in FIG. 7, the drainage pipe 9 is diverted from the water supply pipe 2 in an inverted U-turn shape, and the check valve 10b is arranged to be closed by the water supply pressure. Is more preferable.

In the above description, the case of using the reverse current timer has been described as the means for stopping the power supply for the reverse current cleaning, that is, the means for turning off the reverse current circuit 14 in the figure, but the present invention is not limited to this. For example, the following various sensors can be used. (A) Capacitance sensor that outputs a signal by detecting the integrated electric capacity of the reverse electric cleaning power supply (b) Current sensor that detects a change in current during reverse electric power supply and outputs a signal (c) Reverse electric cleaning 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 reverse power supply and outputs a signal (e ) PH sensor that detects a pH change in water in the electrolytic cell during reverse electrolysis cleaning power supply and outputs a signal Note that the sensors (b), (c), (d), and (e) are reverse electrolysis cleaning power supply. As a change with time, the change in the current or conductivity of the electrolytically treated water or the change in the temperature or pH value of the electrolytically treated water is used to output each change as an electric signal. Then, by the output signal of the sensor, the reverse power circuit 14 in the electric circuit diagram is opened to stop the power supply.

When the switch means 8 for controlling the switching between the forward electrolysis and the reverse electrolysis cleaning electrolysis is divided into the water passage detection switch 8b and the water supply stop detection switch 8c, the water passage detection switch 8b is not provided. A voltage of positive electrolysis polarity is applied to the electrode of the electrolytic cell by a control signal (for example, an ON signal), and even if the water supply stop detection switch 8c is turned on, the positive electrolysis voltage application is maintained and the water supply stop detection is performed. Switch 8c
When the power is turned off, the polarity of the applied voltage is switched to supply power for reverse electrolysis cleaning, and after a predetermined time has passed, the water flow detection switch 8
When b is turned off, the reverse electrolysis cleaning bulb charge may be stopped (see claim 8).

In the above embodiment, the case of performing the reverse electrolysis cleaning and draining the residual water every time the electrolysis of the predetermined polarity, that is, the production operation of the electrolytic ion water is stopped, is explained.
It is also possible to perform electrolysis of a predetermined polarity several times, and perform reverse electrolysis cleaning and drainage of residual water when a predetermined electrolysis integrated value is reached. Therefore, in the embodiment shown in FIGS. 11, 12 and 14, the electrolysis integrating circuit 30 is separately provided in the electrolysis electric circuit.
When the integrating circuit 30 reaches a predetermined integrated value, the reverse circuit 14
There is provided a relay switch 31 for conducting the.
In addition, in the embodiment of FIG. 12, it is necessary to keep the electric valve circuit 15 in a non-conducting state until the integrated value is reached. Therefore, when the integrated circuit 30 reaches the integrated value, the relay contact 32 that turns off the electric valve circuit 15 is provided. It is provided.

Sparking occurs when the predetermined polarity is switched to the reverse polarity inversion instantaneously. To prevent this,
It is desirable to temporarily stop the voltage application and then switch to the reverse voltage application. The purpose of this is, for example, as shown in FIG. 11, FIG. 12, and FIG.
3 and the relay contact 34 for turning off the reverse electric circuit 14 by the timer 33 for a predetermined short time.

Further, since the electrolytic cell 1 is easily heated at the time of reverse charging, a trouble is likely to occur when a normal voltage is applied for a long time. Therefore, it is desirable to reduce the voltage by means of half-wave rectification or the like at the time of reverse power supply. FIG. 15 exemplifies a circuit in which an applied current is half-wave rectified at the time of reverse charging.

[0043]

According to the present invention, the residual water is not drained during the reverse electrolysis cleaning when the electrolysis cleaning is performed after the electrolytic ion water is generated.
Drainage is started after the reverse power supply is stopped. Therefore,
Since the power for reverse electrolysis cleaning is always supplied in a state where the electrolytic cell is filled with water, the reverse electrolysis cleaning action and the cleaning effect are surely improved over the entire area of the electrolysis cell during a predetermined time.

Further, since the drainage pipe for draining the residual water after cleaning is provided in the lower part of the electrolytic cell, which is different from the electrolytic water discharge pipe, there is no possibility that cleaning wastewater will be mixed with drinking electrolytic water or the like. It will surely be resolved.

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

By lowering the applied voltage during the reverse electrolysis cleaning, the electrolytic bath is prevented from being heated, so that the reverse electrolysis cleaning can be continued for a long time. As a result, the acidification of the cathode chamber dissolves not only the electrode but also the calcium on the surface of the electrolytic diaphragm, further improving the cleaning effect.
