Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an improvement in an electrolyzed ionized water generation device that generates alkaline ionized water and acidic water by electrolyzing tap water, etc. In addition to using electrodes made of a material that can reverse the polarity and continue the electrolyzed water generation operation, the open signal time of the flow switch valve installed in the water supply and drainage system of the electrolyzer is integrated, and the integrated output signal is applied at predetermined intervals. The present invention relates to an electrolytic ionized water generating device that performs electrolysis by switching voltage polarity.

[Conventional technology]

The electrolytic ionized water generator supplies water to an electrolytic tank with a positive and negative electrode facing each other, and applies a DC voltage between the electrodes to electrolyze it into alkaline water and acidic water. Calcium and other scales precipitate and adhere to the cathode, reducing electrolytic efficiency. For this reason, a cleaning method is used in which scale is removed by reversing the polarity of the applied voltage when the electrolysis time at a predetermined voltage polarity reaches a certain time.

[Problem that the invention seeks to solve]

By the way, in this type of conventional water electrolysis device, materials used exclusively for the anode and cathode are used for the electrodes, so they are not suitable for long-term electrolysis with the voltage polarity reversed.

Therefore, conventional polarity reversal is only for the purpose of cleaning, takes a short time, and requires low applied voltage (adjustment). In addition, the original electrolyzed water cannot be obtained during polarity reversal. Therefore, the use of electrolyzed water has to be discontinued.

The purpose of the present invention is to change the voltage polarity of the cathode and anode to 1i1 at a predetermined time.
To provide an electrolyzed water generating device capable of continuing electrolyzed water generating operation by reversing to f+j, and automatically controlling polarity reversal of electrodes based on a signal from a flow switch valve of the electrolyzer. be.

Another object of the present invention is to perform electrolysis by reversing the voltage polarity of the electrolytic cell at predetermined time intervals, and to perform electrolysis by reversing the voltage polarity of the electrolytic cell at predetermined intervals.
An object of the present invention is to provide an electrolyzed water generating device that always drains water of the same properties.

[Means to solve the problem]

The object of the above-mentioned IE of the present invention is to provide an electrolyzer in which a pair of electrodes made of a material capable of performing electrolysis to generate electrolyzed water by reversing the polarity of an applied voltage are disposed opposite to each other in an electrolytic cell having an electrolytic cell; An electrolytic circuit that applies a DC electrolytic voltage to the electrodes of the tank, and an electrolytic circuit that is installed in the electrolyzer's supply channel, alkaline water discharge channel, or acidic water discharge channel, and is connected to the water outlet side pressure and
A flow switch valve that detects the open position of a valve member that opens and closes the flow path based on the pressure difference between the first side pressure and transmits an ON signal; This can be achieved by a fully electrolyzed ionized water generator having a control circuit that reverses the polarity of the applied voltage.

The other object of the present invention can be achieved by providing a flow path switching device that operates in synchronization with the integrated output signal of the flow switch valve in the pair of electrolyzed ionized water discharge paths of the electrolyzed ionized water generating device. can.

[Action of the invention]

Since the electrodes of the electrolyzer are made of an electrode material that allows the electrolyzed water generation operation to be performed by reversing the polarity of the applied voltage, the electrolyzed water generation operation can be continued by reversing the polarity at predetermined intervals.
In this case, scale is simultaneously removed during polarity reversal electrolysis,
A special scale cleaning process is required. Furthermore, since the voltage polarity of the electrolytic circuit is switched at predetermined time intervals based on the integrated output signal of the ON (open) signal time of the flow switch valve, polarity reversal is automated.

When a flow path switching device is provided in a pair of electrolyzed water discharge channels, the properties of water discharged from each of the pair of discharge channels do not change even if the voltage polarity is reversed. Furthermore, when the operation of the flow path switching device is synchronized with the integrated output signal of the flow switch valve, the flow path switching operation is automated.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the electrolytic cell 1 has a pair of electrodes 2.3 for water electrolysis disposed facing each other inside, and a pair of electrode chambers 2a with an electrolysis diaphragm 4 between these two electrodes.

There is a partition at 3a.

On one side (lower part in the figure) of the electrolytic cell 1, an internal electrode chamber 2a,
3a is provided with a water supply channel 5 for supplying raw water, and on the other side, a pair of discharge channels 7 which communicate with the electrode chambers 2a and 3a separately and discharge electrolyzed water generated in each electrode chamber.
8. is provided.

The electrodes 2 and 3 of the electrolytic cell 1 are electrically connected to an electrolytic current circuit 9 that applies a DC voltage for electrolysis, and by applying voltage to the electrodes 2 and 3, the water supplied to the electrolytic cell 1 is controlled. The water is electrolyzed into alkaline ionized water and acidic ionized water, which are removed via respective discharge channels 7 and 8 and covered.

In an electrolyzer having such a configuration, one feature of the present invention is that the pair of electrodes 2 and 3 are made of an electrode material that can withstand the application of electrolytic voltage for both cathode and anode, and the polarity of the applied voltage is reversed to perform electrolysis. The reason is that it has become possible to perform electrolysis for water production.

Examples of such electrode materials include ferrite, magnetite, ceramics, and other ceramics that have been surface-treated with gold or platinum using higusuri, and other conductive materials that can be used as positive electrodes. Ceramics; titanium; titanium alloy; titanium coated with tl (metal plating); or an alloy that prevents wear as a positive electrode from collapsing on the surface of the electrode by the electric charge of the alloy's ions. Examples include materials.

A flow switch valve 10 that detects the flow of water and sends a signal is installed in either the water supply channel 5 or the electrolyzed water discharge channel 7 or 8 of the electrolytic cell 1, and its ON signal (valve open signal) is The electrodes 2.3 are manually operated by a control circuit 17, which will be described later, which switches and controls the polarity of the electrolytic current circuit 9.
A DC electrolytic voltage of a predetermined polarity is applied to.

The flow switch valve IO opens and closes the valve member of the fluid passage with a valve body that operates based on the pressure difference between the outlet pressure and the outlet pressure of the flow passage,
It transmits a detection signal for the opening/closing position of the valve body, for example, the second

and a diaphragm chamber 12, and a diaphragm 10e.
1111 A valve body 101 for opening and closing the valve member 10d is integrally fixed, and the fluid passage II is opened and closed by the upward operation of the diaphragm lOc. A through hole 13 communicating from the fluid outlet side B to the diaphragm chamber I2 on one side of the diaphragm 1 is formed in the shaft of the valve body 10f, and when the fluid outlet side pressure becomes larger than the inlet side J and F forces, the outlet side I3 Water flows into the diaphragm chamber 12 from the passage 13 and closes the valve part 10d, and conversely, when the pressure on the fluid outlet side 13 becomes lower than the pressure on the inlet side due to drainage etc. The pressure on the person 1'' side becomes relatively high, and the pressure difference causes the valve portion 10d to open.

A magnet 10g is fixed to the valve body]Of, and a transmitting device 10 such as a reed switch that detects the magnet lOg on the casing and transmits a detection signal.

A signal is sent, and when the water flow reaches I, the signal turns off.

Incidentally, FIG. 2b shows a flow switch valve particularly suitable for the apparatus of the present invention, and this one has a first valve that is opened and closed by the main valve element 10d that is operated by the outlet pressure and inlet pressure of water as described above. It has a fluid passage ll and a second fluid passage 11' which is opened and closed by a driven valve element 10[' which is interlocked with the main valve element 10d, and the flow of water is detected as described above depending on the position of these valve elements. This is a two-stage flow switch valve that sends a signal (signal), and can open and close simultaneously the two flow paths of the water supply and drainage system of the electrolyzed ionized water generator.

In the embodiment shown in FIG. 2b, the water supply channel 5 is passed through the fluid passage 11 on the ball valve side (of the two-stage flow switch valve), and the passage 11 on the driven valve side
'Acidic water discharge passage 8 is passed through.

This structure does not allow alkaline water to pass through the flow switch valve 10, but controls the flow switch valve IO and opens and closes the acidic water discharge path 8 by taking in the alkaline water, which has the major effect of preventing calcium carbonate from being deposited in the flow switch valve 10. There are advantages. However, the present invention is not limited to this structure, and it is of course possible to pass the pair of alkaline discharge passages 7 and acidic water discharge passages 8 of the electrolyzer through the pair of passages 11, 11' of the flow switch valve 10.

(As shown in Fig. 1, the ON signal of the flow switch valve is input to the electrolytic control circuit, the ON signal is integrated, and the integrated output is used to perform various controls as described below. This will be explained with reference to FIG.

It is connected to a rectifier circuit 19 via a switch 18, and from the rectifier circuit electrolytic electrodes 2,

A rectifier circuit 20 is connected to a part of the secondary side of the transformer 15 in the second column, and an electrolytic control circuit 17 is connected to the rectifier circuit 20 via a capacitor 21.

The electrolysis control circuit 17 includes at least an electrolysis control section 21 to which the ON signal of the flow switch valve 10 is manually input, an electrolysis relay 22 that responds to the ON signal of the flow switch valve, and an integration circuit section 23 that integrates the ON signal time of the flow switch valve. is equipped.

Further, the control circuit 17 is provided with a polarity reversal relay 24 that is activated by the integration output signal of the integration circuit section 23, and the electrolytic circuit 16 is provided with a contact 24 of the polarity reversal relay 24.

As a result, electrolysis with a predetermined voltage polarity is started by the ON signal of the flow switch valve 10, and when the ON signal time reaches a predetermined integrated value, the polarity reversal relay 24 is activated and its relay contacts 24a and 24b are turned off. By switching, the voltage polarity applied to the electrodes 2 and 3 is reversed.

The integration circuit 23 is equipped with a circuit that operates a polarity reversal relay 24 each time one integration is completed, and thus, each time an integration output signal is transmitted, the contacts 24a and 24b are alternately switched via the polarity reversal relay 24. The voltage polarity is switched at predetermined intervals.

FIG. 3 is an example of a circuit route diagram for implementing the present invention,
It is of course possible to realize the technical idea of the present invention by using another circuit, and the present invention also includes such circuits.

As described above, when the polarity of the electrode is reversed, the properties of the water drained from the electrolyzed water discharge channel are also reversed, causing confusion on the water intake side. In order to prevent this, in the embodiment shown in FIG. 4, a flow path switching device 30 is provided in the electrolyzed water discharge paths 7 and 8.

The flow path switching device 30 includes, for example, a pair of introduction portions 31a and 31b that communicate with the discharge path 7.8, and a drain pipe 32a that separately discharges alkaline water and acidic water.

A slide valve 34 for flow path switching is slidably fitted into a cylindrical casing 33 having a liquid-tight opening.
are provided at regular intervals in the axial direction.

Furthermore, one of the pair of drain pipes 32a and 32b is provided between the introduction portions 32a and 32b of the casing 33, and the other drain pipe 32b has a bifurcated connection portion with the casing 33. The forks 32b (1) and 32b (2) are communicated with both ends of the casing 33, respectively.

The slide valve 34 has two valve bodies 34b and 3 on a rod 34a.
4C are fixed at a predetermined interval, and the valve bodies 34b and 34C move each of the introduction parts 318 and 31b from the state of communication with one of the drain pipes 32a to the casing end by reciprocating movement of the slide valve. The drain pipes 32b are arranged in such a positional relationship that they are alternately switched to a state of communication with the other drain pipe 32b via the drain pipe 32b.

The slide valve 34 is operated by a drive device 35 using a motor 35a or the like. In this case, by synchronizing the polarity reversal of the motor 35a and the electrolyzer 1, the flow path of the flow path switching valve device 30 can be switched at the same time as the polarity of the electrolyzer 1 is switched (the reverse is also possible).

Next, the present invention will be explained in detail.

When the water intake faucet on the water use side of the electrolyzer is opened, the flow switch valve IO opens, and as water flows, the ON signal of the flow switch valve IO is manually input to the electrolysis control section 21 of the control circuit 17, and the electrolysis relay 22 is activated to switch on the flow switch valve IO. The contact 22a is closed and a DC voltage of a predetermined polarity is applied to the electrode.

The ON signal of the flow switch valve 10 is output from the integrating circuit section 23.
The ON signal time is accumulated manually.

When the ON signal time reaches a predetermined integrated value, the integrated output signal activates the polarity reversal relay 24, and its contacts 24a,
By switching 2/lb, the polarity of the voltage applied to the electrodes 2.3 is reversed.

In the present invention, the electrodes 2 and 3 are made of a material that allows electrolyzed water generation operation with the voltage polarity reversed as described above, so even if the polarity is reversed, the electrolyzed water generation operation continues as is, and during reverse electrolysis, the electrolyzed water generation operation continues. Scales such as calcium carbonate generated during polarity electrolysis before the reversal are dissolved and removed with acidic water.

Of course, due to polarity reversal, alkaline water and acidic water are also drained from the electrolyzed water discharge channel through the opposite discharge channel, but discharge channels 7 and 8
If a flow path switching device is installed in the water intake system, water with the same properties will always be discharged without being affected by this.

〔Effect of the invention〕

Since the present invention has the following configuration, it is possible to perform electrolysis to generate electrolyzed water by automatically switching the voltage polarity at predetermined intervals, so that precipitated calcium carbonate etc. are automatically dissolved during the generation of electrolyzed water by reverse electrolysis. , are removed, so no special cleaning operation is required.

Also, turn on the flow switch valve installed in the water supply and drainage system.
Since the signal time is integrated and the polarity reversal is controlled using the integrated signal, there is no risk of malfunction like with a pressure switch, a highly reliable signal can be obtained, and the installation location of the device is restricted. Nor.

In addition, if a flow path switching device is provided in the electrolyzed water discharge path, confusion can be avoided because the predetermined amount of electrolyzed water is always discharged from the water intake snake [I side] even if the polarity is changed.
