Abstract

PURPOSE:To eliminate the trouble caused by the precipitation of Ca by providing the water supply port and water discharge port communicating with either one of a cathode chamber and an anode chamber to one end and other end of the electrolytic cell constituted of the cathode chamber and the anode chamber partitioned by an electrolytic diaphragm. CONSTITUTION:When a water taking-in opening and closing means 9 of an electrolytic unit is opened, the water of a valve operating chamber 20 flows out because the pressure on the downstream side of the valve seat of a main dynamic valve chamber 15 is lowered and the valve member 18 integrated with a diaphragm 19 closes the valve seats 21a, 21b of the respective valve chambers 15, 16 simultaneously with the upward movement of the diaphragm 19. When the opening and closing means 9 is closed, the water pressure on the downstream side of the valve seat of the main dynamic valve chamber 15 rises and water flows in the valve operating chamber 20 through a passage 23. Therefore, the valve member 18 is pressed in the direction of the valve seat by the pressure of the valve operating chamber 20 to simultaneously close the valve seats 21a, 21b of the valve chambers 15, 16. The electrolytic current to the electrolytic unit 1 is turned ON and OFF by the signal of a signal transmitter generated by the movement of the valve member 18.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a continuous water flow type electrolyzed water generation device that electrolyzes water into alkaline ionized water and acidic water, and particularly relates to an electrolyzed water generation device that electrolyzes water into alkaline ionized water and acidic water, and particularly relates to an electrolyzed water generation device that electrolyzes water into alkaline ionized water and acidic water. The present invention relates to an electrolyzed water generating device that controls opening and closing of a water supply pipe of an electrolyzer unit by opening and closing a water drain pipe.

[Problem to be solved by the invention]

The cathode chamber and anode chamber of the electrolytic cell are divided into a cathode chamber and an anode chamber by an electrolytic diaphragm, and water is supplied from one side of the electrolytic cell to both electrolytic chambers for electrolysis. BACKGROUND ART Continuous water flow type water electrolyzers that discharge alkaline ionized water and acidic water separately from an electrolyzed water outlet are widely known for the purpose of producing alkaline ionized water or acidic water.

In this type of electrolyzed water generation device, a two-stage flow valve is installed in a pair of drainage pipes for alkaline water and acidic water, which opens and closes the pair of pipes in conjunction with the opening and closing of one pipe. For example, there is a two-stage flow valve in which the alkaline water passage and the acidic water passage are simultaneously opened and closed when an alkaline water intake faucet is opened and closed.

However, when a flow valve is provided on the drainage side of the electrolytic unit as described above, there is a problem that calcium deposits from alkaline water adhere to various parts of the flow valve, causing it to malfunction. To solve this problem, water is supplied to the electrolytic cell through the flow valve's main valve side passage, which is activated by opening and closing the alkaline water faucet, and the acidic water is discharged through the flow valve's driven valve side passage. I tried that.

However, with this system, the water supply to the electrolytic cell and the acidic water drainage channel can be opened in conjunction by opening the alkaline water drain faucet, but the electrolytic cell is connected to the common water supply channel passing through the main valve side passage of the flow valve. Since water is supplied to the cathode chamber and anode chamber of the electrolytic cell, even if the alkaline drain faucet is closed, the water supplied to the electrolytic cell will flow from the anode chamber to the acid water circuit, and the water supply cannot be stopped. Of course, the same applies to the case where the electrolyzed acidic water is passed through the main valve side passage of the flow valve and the electrolyzed alkaline water is drained through the driven valve side passage.

Therefore, the main object of the present invention is to ensure that the flow valve is not affected by calcium precipitation, and to reliably control the opening and closing of water supply to the electrolyzer unit by operating the opening/closing means of one of the utilized electrolyzed water discharge pipes. The purpose of the present invention is to provide an electrolyzed water generating device that can generate electrolyzed water.

Another object of the present invention is to use a flow valve provided with three systems of fluid valve chambers, so that water can be supplied to the electrolyzer unit by operating the opening/closing means of the alkaline water drainage pipe on the user side as described above. An object of the present invention is to provide an electrolyzed water generating device that can reliably control the opening and closing of water supply, and can also control the opening and closing of a drainage channel for acidic water using the same flow valve.

[Means to solve the problem]

An electrolyzed water generating device for achieving the above-mentioned main object of the present invention comprises an electrolytic cell by partitioning a cathode and an anode which are arranged oppositely into a cathode chamber and an anode chamber by an electrolytic diaphragm. One end side and the other end side are provided with a pair of water supply ports and a pair of discharge ports that communicate independently with either the cathode chamber or the anode chamber, and water is taken into a drain pipe that communicates with one of the electrolyzed water discharge ports. a water electrolyzer unit equipped with an opening/closing means; at least two independent valve chambers each having a fluid inlet and an outlet, the interior of which is divided into an inlet side and an outlet side by a valve seat;
A valve operating chamber is provided in the valve casing in multiple stages and partitioned by a transverse diaphragm on the upstream side of the valve seat of one of the valve chambers, and the valves of the plurality of valve chambers are provided in the axial direction of the rev casing A common valve member for interlockingly controlling the opening and closing of the seat is disposed and fixedly supported by the diaphragm, and the valve operating chamber and the downstream side of the valve seat of either valve chamber are communicated with each other through a passage to form a main operating valve chamber. a multi-stage flow valve, wherein the fluid outlet of the main valve chamber of the multi-stage flow valve is communicated with the water supply port of the electrode chamber on the side that communicates with the water intake opening/closing means of the electrolyzer unit, and One of the fluid outlets is connected to the water supply port of the electrode chamber on the other side of the electrolyzer unit, and the fluid inlets of the two valve chambers of the flow valve communicating with the pair of water supply ports of the electrolyzer unit are connected to the raw water supply port. The structure is as follows.

In addition, an electrolyzed water generating device for achieving the above-mentioned objective of the present invention has an electrolytic cell constructed by partitioning a cathode and an anode, which are arranged oppositely, into a cathode chamber and an anode chamber by an electrolytic diaphragm. A pair of water supply ports and a pair of discharge ports are provided at one end and the other end of the electrolytic cell, each independently communicating with either the cathode chamber or the anode chamber, and a faucet or the like is provided at the alkaline water discharge port leading to the cathode chamber. A water electrolyzer unit equipped with a pipe line having an opening/closing means: Three independent valve chambers each having a fluid inlet and an outlet, the interior of which is divided into an inlet side and an outlet side by a valve seat, are installed in the valve casing. A valve operating chamber is provided in three stages within the valve chamber and partitioned by a transverse diaphragm on the upstream side of the valve seat of one of the valve chambers, and the valve seats of the plurality of valve chambers are interlocked in the axial direction of the valve casing. A multi-stage flow valve is provided, in which a common valve member for controlling opening and closing is arranged and fixedly supported by the diaphragm, and the valve operating chamber and the downstream side of the valve seat of either valve chamber are communicated through a passage. The fluid outlet of the valve chamber that opens and closes the passage to the valve operating chamber is communicated with the water supply port leading to the cathode chamber of the electrolyzer unit, and the fluid outlet of one of the other valve chambers is connected to the anode chamber of the electrolyzer unit. The acid water outlet leading to the anode chamber of the electrolyzer unit is also connected to the fluid volume of the remaining valve chamber, and the two flow valves communicating to the pair of water inlets of the electrolyzer unit The fluid inlets of the two valve chambers serve as raw water supply ports.

It is desirable that the electrolytic diaphragm of the electrolyzer unit maintains sufficient mechanical strength to not be deformed or damaged by the water pressure difference between the cathode chamber and the anode chamber of the electrolytic cell.

The flow valve may be provided with a switch means for detecting the opening/closing position of the flow passage of the valve member and transmitting a signal, and the electrolytic current circuit of the electrolyzer unit may be ON/OFF controlled by the detection signal.

Furthermore, the partition between each valve chamber of the flow valve is a valve. A pair of outlet ports of the valve are separately communicated with these two water supply ports. Therefore, when you first open the opening/closing means such as a faucet installed in the drainage pipe of electrolyzed water (alkaline water or acidic water) on the user side, the water pressure downstream of the valve seat in the main valve chamber changes to the water pressure in the valve operating chamber above the diaphragm. As the water in the valve operating chamber flows out, the water pressure on the upstream side of the valve seat in the main valve chamber becomes relatively high.For this reason, the valve body integrated with the diaphragm is connected to a pair of water supply pipes. The channels are simultaneously opened to allow water to flow to the electrolyzer unit.

On the other hand, the two water flow paths from the pair of valve chambers of the flow valve to the pair of drain pipes of the electrolyzer unit are independent, so when the opening/closing means of the drain pipe of the electrolyzed water on the usage side is closed, the above-mentioned As a result, the water pressure downstream of the valve seat in the main valve chamber increases and water flows into the valve operating chamber.As a result, the valve element integrated with the diaphragm that partitions the valve operating chamber causes The two valves close simultaneously and the water supply to the electrolyzer unit is cut off.

Next, the invention described in claim (2) of the present application provides an opening/closing means in the alkaline water drainage pipe, and communicates the main valve chamber outlet side of the flow valve with the water supply port of the cathode chamber communicating with the alkaline water drainage pipe. Since the drainage pipe is connected to the inlet side of the other driven valve chamber of the three-stage flow valve, in addition to the above-mentioned action, when the on-off valve of the alkaline water drainage pipe is opened or closed, acidic water The drain pipes of the two drains will be opened and closed by the valve body of the same flow valve.

If you open or close the opening/closing means of the drain pipe on the user side when the water pressures in the cathode and anode chambers are balanced, the electrolytic diaphragm may be deformed or damaged due to the pressure difference between the cathode and anode chambers. This problem can be solved by adding reinforcing nets on both sides.

If the flow valve is equipped with a switch device that detects the opening/closing position of the valve body and sends a signal, this signal can be used to control the electrolysis ON/OFF of the electrolyzer unit, thereby controlling the electrolyzed water drainage on the user side. The operation of the electrolyzer unit is controlled by operating the opening/closing means of the conduit.

Furthermore, if the partitions between each valve chamber of a flow valve are constructed with a diaphragm that is integrated with the valve body, not only will the operating resistance of the valve body become smaller, but changes in water pressure will act on each partition diaphragm, causing the valve body to operate. help.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a continuous water flow type electrolyzer unit that electrolyzes water supplied from a water supply port and drains it as alkaline ionized water and acidic water from a pair of discharge ports.

The cathode chamber 5 and the anode chamber 6 are separated by an ion exchange partition such as an electrolyzer unit or wall used in the electrolyzed water generating device of the present invention.
A pair of water supply lowers a and 8a are provided on one side (lower part of the figure) of the electrolytic cell, which communicate independently with the cathode chamber 5 and the anode chamber 6, respectively. A pair of electrolyzed water discharge lowers b and 3b are also provided on the other side of the tank (in the upper part of the figure), which communicate independently with the cathode chamber 5 and the anode chamber 6, respectively.

Thus, the passageway passing through the cathode chamber 5 and the passageway passing through the anode chamber 6 of the electrolyzer unit 1 constitute independent passageways from the water supply lowers a, 8a to the discharge lowers b, 8b.

In this electrolyzer unit 1, a drain pipe 10 having an opening/closing means 9 such as a faucet is connected to one electrolyzed water outlet (alkaline water outlet 8a in the illustrated embodiment).
The other electrolyzed water outlet (acidic water outlet 8b in the illustrated embodiment)
) is connected to a drainage pipe line 12 leading to a drainage drain 11.

The electrolysis diaphragm 4 of the electrolyzer unit 1 has a cathode chamber 5 and an anode chamber 6.
It is desirable to maintain mechanical strength so that it will not be deformed or damaged by the water pressure difference.

For this reason, when a thin film-like electrolytic diaphragm is used as shown in the figure, reinforcing support nets 13 are stretched on the inside and outside of the diaphragm 4 to support the diaphragm 4. Instead of this, it is important to make the diaphragm 4 of a porous material such as unglazed fired material, which is microporous enough to provide the diaphragm itself with a supporting force.

14 is a flow valve used in the present invention, and this flow valve 14 has a plurality of valve chambers 15 and 16 each having a fluid inlet and an outlet arranged in upper and lower stages in the axial direction of the valve caning 17. The valve seats 15a and 16a of the valve chambers 15 and 16 are opened and closed by a common valve member 18, and there is a transverse A valve actuation chamber 20 is provided which is partitioned off by a directional diaphragm 19 .

The valve member 18 is a valve seat 15a of each valve chamber 15,16.

Valve bodies 21a and 21b corresponding to valve body 16a are attached to a series of valve rods 22, and are fixed and supported by a diaphragm 19 that partitions the valve operating chamber 20.

One of the valve chambers communicates with the valve operating chamber 20 via a passage 23, and constitutes a main operating valve chamber. In the illustrated embodiment, the valve operating chamber 20 and the downstream side of the valve seat of the upper valve chamber 15 are communicated through a passage 23 formed in the shaft of the valve rod 22, and the pressure between the valve operating chamber 20 and the downstream side of the valve seat of the main valve chamber 15 is The difference is such that fluid moves through the passage 23. Note that the valve member 18 is the spring 2
4, it is lightly biased toward the valve seat. Reference numeral 25 denotes a signal transmitting device that detects the valve open/close position of the valve member 18 and outputs an open/close signal.
The valve member 18 includes a switch member 25b such as a reed switch fixed opposite the magnet 25a to the valve member 18.
The magnet 25a approaches and leaves the switch member 25b by the valve opening/closing operation, and a signal is transmitted from the switch member 25b due to magnetic field fluctuation.

The valve chambers 15 and 16 may be separated by a normal partition wall, but preferably, as shown in the figure, a flexible bellows or diaphragm 26 fixed between the inner wall of the valve casing and the valve member 18 is used to seal the space between the valve chambers 15 and 16. do.

The present invention is directed to the outlet 2 of the main valve chamber 15 of this flow valve 14.
7b is connected to the water supply lower a of the electrode chamber 5, which communicates with the water intake opening/closing means of the electrolyzer unit 1, via the water supply pipe 27c, and the outlet 28b of the other valve chamber 16 (driven valve chamber)
The water supply pipe 28c is connected to the other electrode chamber 6 of the electrolyzer unit 1.
fluid population 27a of both valve chambers 15, 16,
Raw water is pumped through 28b.

(Thus, in the embodiment shown in FIG. 1, when the water intake opening/closing means 9 of the electrolyzer unit 1 is opened, the pressure on the downstream side of the valve seat of the main operating valve chamber 15 decreases, so water in the valve operating chamber 20 flows out, and the diaphragm 1
9 moves upward, the valve member 18 integrated therewith simultaneously closes the valve seats 2Ia, 21b of each valve chamber 15, 16.

On the other hand, since the passage from the main operating valve chamber 15 to the opening/closing means 9 forms a sealed circuit by an independent water supply lower a, when the opening/closing means 9 is closed, the water pressure downstream of the valve seat of the main operating valve chamber 15 increases. It flows into the valve actuation chamber 20 through the passage 23 . Therefore, the pressure in the valve actuation chamber 20 pushes the valve member 18 toward the valve seat, and the valve seats 21a, 21b of the valve chambers 15, 16 close simultaneously. By turning on and off the electrolytic current to the electrolyzer unit 1 using a signal from the signal transmitter 25 generated by the movement of the valve member 18 at this time, the electrolyzer is automatically operated by operating the user-side electrolyzed water faucet.

Although FIG. 1 shows an example in which alkaline water is used, the outlet 27b of the main operating valve chamber 15 is connected to the water supply lower a of the cathode chamber 5, but the present invention connects the outlet 27b of the main operating valve chamber 15 to the anode. The same applies to the case where the acidic electrolyzed water is used by connecting to the water supply port 8a of the chamber 6.

FIG. 2 shows another embodiment of the present invention, and this embodiment is premised on an apparatus intended for the use of alkaline water. That is, the flow valve 14 is connected to three systems of fluid valve chambers 15.
．． This embodiment is the same as the embodiment shown in FIG. 1 except that the acidic water drainage pipe 12 is connected to the inlet 30a of the additional driven valve chamber 29.

In this embodiment, the water supply to the electrolytic cell is opened and closed by opening and closing the alkaline water intake faucet 9, and at the same time, the same flow valve 14 is used to open and close the acidic electrolyzed water drainage pipe 12. The aim is to eliminate acidic water dripping.

〔Effect of the invention〕

As described above, in the present invention, since the flow valve is not affected by alkaline water, there is no trouble caused by calcium precipitation.

Therefore, long-term continuous operation is possible and the life of the flow valve is significantly improved.

If you leave the acidic water drainage channel open as in the past, there is a risk that bacteria may enter the electrolytic cell, and as a countermeasure, installing a check valve in the pipeline will prevent the valve from being closed by the acidic water. There was a problem of early breakage, but this problem can be solved if a three-stage flow valve is used to open and close the drainage of acidic electrolyzed water, as in the present invention.

In addition, since the electrolytic diaphragm has a supporting force against the pressure difference in the electrode chamber, the diaphragm will not be deformed or damaged when the water intake faucet is opened or closed.
