[0004]

In order to solve the above-mentioned problems, in the present invention, a salt solution tank, an acidic water generator containing a hydrogen-substituted cation exchange resin, a non-diaphragm type electrolytic cell, It has a pumping means for pumping the saline solution from the saline solution tank to the non-diaphragm type electrolysis cell via the acidic water generation device, a DC power supply, and a control device. And a water flow passage formed by a pair of smooth wall surfaces facing each other in parallel, an anode plate forming one of the pair of wall surfaces, a cathode plate forming the other of the pair of wall surfaces, and a water flow passage.

In the apparatus for producing and discharging hypochlorous acid-containing acidic water according to the present invention, the saline solution stored in the saline solution tank is sent to the acidic water producing apparatus by the pressure feeding means. The saline solution that flows into the acidic water generator is replaced with hydrogen ions by replacing the calcium and magnesium ions, which are the hardness components in the saline, with hydrogen ions by the hydrogen-substituted cation exchange resin installed in the acidic water generator. It becomes saline. The acidic saline solution flowing out of the acidic water generator flows into the saline solution supply channel of the non-diaphragm type electrolytic cell, and further flows into the water channel. Between the anode plate forming one of the pair of wall surfaces forming the water passage and the cathode plate forming the other of the pair of wall surfaces forming the water passage, a DC voltage is applied by the DC power supply device,
The flowing water of the acidic saline solution flowing through the water flow path between the anode plate and the cathode plate is electrolyzed. Hypochlorous acid-containing acidic water generated near the anode and flowing along the wall of the water flow channel formed by the anode plate, and alkaline water generated near the cathode and flowing along the wall of the water flow channel formed by the cathode plate Flows from the downstream end of the water flow passage into the electrolytic water recovery flow passage and mixes.

The hypochlorous acid-containing acidic water flowing through the electrolytic water recovery flow path is discharged through an acidic water outlet. The operation of the pumping means and the diaphragmless electrolytic cell is controlled by a control device.

In the apparatus for generating and discharging hypochlorous acid-containing acidic water according to the present invention, since the acidic water is generated by the acidic water generating apparatus, the electrolytic water flowing out of the non-diaphragm type electrolytic cell is separated into acidic water and alkaline water. It is not necessary to divide the wastewater into wastewater, and a wastewater recovery tank for recovering alkaline water is not required. Further, since the entire amount of the saline solution stored in the saline solution tank is used as hypochlorous acid-containing acidic water, the saline solution tank provided in the hypochlorous acid-containing acidic water generation and discharge device according to the present invention is International Publication WO 96/03 having a sufficient capacity to store not only the saline required for producing acidic water to be used but also the saline required for producing discarded alkaline water.
It is possible to reduce the size compared with the saline solution tank provided in the apparatus for generating and discharging hypochlorous acid-containing acidic water of No. 881. Therefore, the hypochlorous acid-containing acidic water generation / discharge device according to the present invention can be further miniaturized than the hypochlorous acid-containing acidic water generation / discharge device of WO 96/03881. Acidic hypochlorous acid aqueous solution contains hypochlorous acid (HCl
Since O) is mainly present, the hypochlorous acid-containing acidic water discharged from the hypochlorous acid-containing acidic water generation and discharge device according to the present invention has a sufficient sterilizing power.

In a preferred embodiment of the present invention, a hollow fiber filter is provided between the hydrogen-substituted cation exchange resin and the non-diaphragm type electrolytic cell. Bacteria propagated in the cation exchange resin are removed from the saline solution flowing into the non-diaphragm type electrolysis tank by the hollow fiber filter disposed between the hydrogen-substituted cation exchange resin and the non-diaphragm type electrolysis tank. As a result,
The occurrence of a situation where the sterilizing power of the hypochlorous acid-containing acidic water discharged from the hypochlorous acid-containing acidic water generation / discharge device is reduced is prevented.

In a preferred embodiment of the present invention, the hypochlorous acid-containing acidic water generating and discharging apparatus includes a cartridge in which a hydrogen-substituted cation exchange resin and a hollow fiber filter are integrated. By integrating the hydrogen-substituted cation exchange resin and the hollow fiber filter into a cartridge,

The control device 9 is started. The CPU of the control device 9 is started, the pump 6 is started via the pump driving circuit, and the diaphragmless electrolytic cell 1 is connected via the electrolytic cell driving circuit and the harness 14.
To the spraying device drive circuit and the harness 14
And a high-frequency piezoelectric element driving power is supplied to the spraying device 2 via. As shown by the arrow in FIG. 1, the operation of the pump 6 causes the saline solution to be supplied from the saline solution tank 5 to the acidic water generator 7.
Through the saline solution supply tube 11 of the harness 14,
The pressure is fed to the non-diaphragm type electrolytic cell 1. When the saline solution passes through the acidic water generator 7, calcium ions and magnesium ions, which are hardness components in the saline solution, are replaced with hydrogen ions by the hydrogen-substituted cation exchange resin disposed in the acidic water generator. , The saline solution becomes an acidic saline solution.

As indicated by the arrows in FIG. 6, the acidic saline solution flowing into the saline solution inlet 22 of the diaphragmless electrolytic cell 1 flows into the saline solution supply channel 26, while flowing through the saline solution supply channel 26. It flows into the water passage 25. A DC voltage is applied between the anode plate 19 and the cathode plate 20 via the electrolytic cell drive circuit of the control unit 9, and the flowing water of the acidic saline solution flowing through the water passage 25 is electrolyzed. Hypochlorous acid-containing acidic water is generated near the anode plate 19, and alkaline water is generated near the cathode plate 20.

As indicated by the arrows in FIG. 6, the hypochlorous acid-containing acidic water generated near the anode plate 19 and flowing along the anode plate 19 and the hypochlorous acid-containing acidic water generated near the cathode plate 20 along the cathode plate 20 The flowing alkaline water flows into the electrolyzed water recovery flow path 28 from the downstream end of the water flow path 25.

It flows out of the non-diaphragm type electrolytic cell 1 through the acidic water outlet 24 while mixing. By mixing the hypochlorous acid-containing acidic water and the alkaline water in the electrolytic water recovery flow path 28, the acidity and the alkalinity caused by the electrolysis are neutralized. As a result, the electrolyzed water flowing through the electrolyzed water recovery flow path 28 becomes hypochlorous acid-containing water having a pH before electrolysis, that is, hypochlorous acid-containing acidic water.

A non-diaphragm type electrolytic cell 1 through an acidic water outlet 24
The hypochlorous acid-containing acidic water flowing out of the tank flows into the open spray tank 32 of the spray device 2 and fills the open spray tank 32. The hypochlorous acid-containing acidic water filling the open spray tank 32 soaks one surface of the porous plate 31 covering the open end of the open spray tank 32.

The sprayed hypochlorous acid-containing acidic water is
It is applied to an inflamed part of atopic dermatitis, a gangrene part due to diabetes, etc., or a bedsore such as a bedridden elderly person, to sterilize MRSA propagated in the part and prevent itching and suppuration of the part.

After the spraying is completed, when the user presses the hand switch 3 to stop the operation of the control device, the CPU of the control device 9
Of the pump 6, the diaphragmless electrolytic cell 1, and the spraying device 2 are stopped. When the operation of the pump 6 is stopped, the supply of the acidic saline solution to the diaphragmless electrolytic cell 1 is stopped. The user replenishes the saline solution tank 5 of the main body 10 with saline as needed, replaces the hydrogen-substituted cation exchange resin in the acidic water generator 7, and replaces the battery of the DC power supply 8.

In the apparatus A for producing and discharging hypochlorous acid-containing acidic water, the anode plate 19 and the cathode plate 20 of the non-diaphragm type electrolytic cell 1 are provided.
Are opposed to each other without the interposition of a diaphragm, so that the distance between the electrodes is narrower and the electric resistance of the saline solution existing between the electrodes is smaller than that of a conventional generator using a diaphragm type electrolytic cell. Therefore, in the present apparatus A, the saline solution is electrolyzed with less electric power as compared with a generator using a conventional diaphragm type electrolytic cell. As a result, the device A is made smaller and more portable because of the downsizing of the non-diaphragm type electrolytic cell 1 due to the narrowing of the distance between the electrodes and the downsizing of the DC power supply device 8 and the control device 9 due to the lower power consumption. The electrolytic spray unit 4 is palm-sized. Since the entire apparatus is miniaturized and portable, a user can easily carry the apparatus A to an arbitrary place and use it. Since the electrospray unit 4 is palm-sized, the user holds the electrospray unit 4 connected to the main body 10 through the hearth 14 in his / her hand and places the hypochlorous acid-containing acidic water on any part of the body. Can be applied. Therefore, the usability of the device A is high.

In the apparatus A for producing and discharging hypochlorous acid-containing acidic water, the anode plate 19 and the cathode plate 20 of the non-diaphragm type electrolytic cell 1 are used.
By reducing the distance between the electrodes, the electrolysis power supply can be made into a battery through lowering the electrolysis voltage and lowering the electrolysis power. In the apparatus A for generating and discharging hypochlorous acid-containing acidic water, the distance between the anode plate 19 and the cathode plate 20 of the diaphragmless electrolytic cell 1 is set to about 0.2 mm to about 1.0 mm. Not only the power source but also the pump drive power source has been realized by optimizing the water flow resistance of the water flow passage 25.

In the apparatus A for producing and discharging hypochlorous acid-containing acidic water, the spraying device 2 is constituted by the piezoelectric element 30 and the porous plate 31 having one end fixed to the piezoelectric element 30.

In the apparatus A for generating and discharging hypochlorous acid-containing acidic water, the electrospray unit 4 and the harness 14 were stored in the opening of the main body 10, so that the entire apparatus was integrated, downsized, and transported.

In the apparatus A for generating and discharging hypochlorous acid-containing acidic water, since the acidic water is generated by the acidic water generator 7, the electrolytic water flowing out of the non-diaphragm type electrolytic cell 1 is separated into acidic water and alkaline water. It is not necessary to divide the wastewater into wastewater, and a wastewater recovery tank for recovering alkaline water is not required. Further, since the entire amount of the saline solution stored in the saline solution tank 5 is used as the hypochlorous acid-containing acidic water, the saline solution tank 5 provided in the hypochlorous acid-containing acidic water generation and discharge device A is Hypochlorous acid containing WO96 / 03881 which has a sufficient capacity to store not only the saline required for producing the acidic water to be used but also the saline required for producing the discarded alkaline water. The size can be reduced as compared with the saline solution tank provided in the acidic water generation and discharge device. Accordingly, the apparatus A for producing and discharging acidic water containing hypochlorous acid is disclosed in International Publication WO96 / 03.
It is possible to further reduce the size of the apparatus for generating and discharging hypochlorous acid-containing acidic water of No. 881. Since the hypochlorous acid (HClO) having strong sterilizing power is mainly present in the acidic hypochlorous acid aqueous solution, the hypochlorous acid-containing acid discharged from the hypochlorous acid-containing acidic water generating and discharging device A is mainly present. Water has sufficient bactericidal activity.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. A hollow fiber filter may be provided at a location downstream of the hydrogen-substituted cation exchange resin in the acidic water generator 7. The bacteria propagated on the cation exchange resin are removed from the saline flowing into the non-diaphragm type electrolytic cell 1 by the hollow fiber filter. As a result, the occurrence of a situation in which the sterilizing power of the hypochlorous acid-containing acidic water discharged from the hypochlorous acid-containing acidic water generation and discharge device A is reduced is prevented.

The acidic water generator 7 may be configured as a cartridge in which a hydrogen-substituted cation exchange resin and a hollow fiber filter are integrated. By configuring the acidic water generating device 7 as a cartridge in which the hydrogen-substituted cation exchange resin and the hollow fiber filter are integrated, the hydrogen-substituted cation exchange resin when the life of the hydrogen-substituted cation exchange resin has expired is exhausted. Exchange of the ion exchange resin becomes easy.

The spray device 2 may be removed and the hypochlorous acid-containing acidic water flowing out from the acidic water outlet 24 may be discharged from the acidic mist outlet 15a of the electrolytic spray unit 4.

The concentration of hypochlorous acid may be adjusted according to the application by variably controlling the electrolytic current applied to the electrolytic cell 1. For example, by controlling the concentration of hypochlorous acid to about 0 ppm to 0.5 ppm and combining it with a dryer, a "treatment dryer" for keeping hair clean and supple can be obtained. Hypochlorous acid concentration from 0ppm to 1pp
m, and by combining it with a heater for spraying heated mist, a "beautifying device" that makes the skin finer can be obtained. Hypochlorous acid concentration of 1ppm to 5pp
By setting it to about m, a "skin cleaner" that discharges a lotion for skin care can be obtained. By setting the hypochlorous acid concentration to about 5 ppm to 50 ppm, a "kitchen spray" for removing bacteria from a cutting board or the like can be obtained. By adjusting the concentration of hypochlorous acid to about 2 ppm to 10 ppm, a "bottom spray disinfector" that controls the hygiene of the buttocks and prevents hemorrhoids can be obtained. Hypochlorous acid concentration from 0ppm to 2p
pm and being incorporated in a refrigerator or a food showcase, a "refrigerator with a function of maintaining freshness" can be obtained.
By making the concentration of hypochlorous acid about 0 ppm to 2 ppm and atomizing while heating in the bathroom, a "mist sauna apparatus" for whole body beauty can be obtained.
