Next, a mode for carrying out the present invention will be described with reference to the drawings.

<First Embodiment>
As shown in FIG. 1, the electrolyzed water injection device 1 has a housing 2 and a support column 3 arranged on the upper portion of the housing 2. The electrolyzed water injection device 1 injects the electrolyzed water stored in the electrolyzed water tank 11 inside the housing 2 from the injection nozzle 16 attached to the support column 3.

Although not shown, in the electrolyzed water injection device 1, a control unit 20 (not shown) composed of an MPU (Micro Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown) injects electrolyzed water. The entire device 1 is controlled in an integrated manner.

The housing 2 houses an electrolyzed water tank 11, a pump 12, and a water pressure gauge 13. The electrolyzed water tank 11 is a tank for storing electrolyzed water, and its configuration is not limited, and a known tank can be used. For example, a tank having a capacity of 10 to 100 liters, such as a gallon bottle of about 10 liters, is preferably installed.

The electrolyzed water to be stored is not particularly limited, and any of acidic electrolyzed water having a pH of 2 to 6, neutral electrolyzed water having a pH of 6 to 8 and alkaline electrolyzed water having a pH of 9 to 13.5 may be used for injection. Electrolyzed water is used according to the application. For example, acidic electrolyzed water is preferably used for the purpose of sterilization.

A pump 12 is connected to the electrolyzed water tank 11 via a pipe 21. The pump 12 sucks the electrolyzed water from the electrolyzed water tank 11 via the pipe 21 and supplies it to the injection pipe 22. The configuration of the pump 12 is not limited, but for example, a DC pump using a DC (Direct Current) motor is preferably used. In this DC pump, the rotation speed of the DC motor changes according to the applied voltage value, and the output of the pump (the amount of electrolyzed water pumped from the electrolyzed water tank 11) changes. Further, an AC (Alternating Current) pump may be used in the same manner.

A water pressure gauge 13 for measuring the water pressure inside the injection pipe 22 is attached to the injection pipe 22. The control unit 20 (not shown) monitors the value of the water pressure gauge 13 and adjusts the flow rate of the electrolyzed water sucked from the electrolyzed water tank 11 by the pump 12 so that the water pressure of the injection pipe 22 is within a predetermined pressure range. ..

The strut portion 3 is a strut to which the injection member 14 is attached, is fixed to the rear side of the housing 2, and projects upward from the housing 2. The height and shape of the strut portion 3 are not particularly limited, and may be appropriately changed depending on the object to be injected. The target to be jetted is not particularly limited, and examples thereof include humans wearing protective clothing and white coats, and objects such as food and machinery. Hereinafter, as an example, a case where the injection target is a human being will be described.

As the strut portion 3, an elongated rectangular plate-shaped member is used, and the height of the upper portion of the strut portion 3 is set to about 170 to 220 cm. Injection members 14 (14A, 14B) are attached to the support columns 3 in a state of being separated in the vertical direction.

As shown in FIG. 2, the injection member 14 has a rectangular parallelepiped shape as a whole, and has a circular opening 17A on the front side of the injection housing 17. An injection nozzle 16 is installed at the center of the opening 17A in the vertical and horizontal directions. The injection nozzle 16 has an injection hole (not shown) formed on the tip surface located slightly rearward of the opening 17A. The injection nozzle 16 is fixed to a plate-shaped injection fixing portion 16A extending from the inner wall surface of the injection housing 17.

The injection nozzle 16 has a structure capable of ejecting a finely divided fluid from an injection hole on the front side (opening 17A side), and can vigorously inject electrolyzed water by the pressure of the supplied liquid. Is. The shape of the injection nozzle 16 is not limited, and a known injection nozzle is appropriately selected and used. For example, a fan-shaped nozzle (flat nozzle) that cuts out the circumferences of ellipses, diamonds, and circles that are long in one direction and injects them into a shape like the human eye, and an empty conical nozzle that has an annular spray pattern (holo). It is preferable to use a pressure mesh method for forming fine mist-like droplets by applying pressure to a narrowed flow path such as a cone nozzle) or a filled cone nozzle (full cone nozzle) and passing the mesh through the flow path.

For example, an empty conical nozzle can be preferably used as the injection nozzle. The injection angle is appropriately selected depending on the object to be injected, but is preferably 60 to 120 °, more preferably 70 to 100 °. The injection angle is the angle at which the tip of the injection nozzle 16 spreads from the central axis in the injection direction. For example, when a conical injection hole having no tip is formed so as to open at 60 ° from the mesh, the injection angle is 60 °.

The water pressure at the time of injection is appropriately adjusted according to the size of the object to be injected, the distance to the object to be injected, and the like, but is preferably 0.2 to 20 Mpa, more preferably 0.3 to 10 Mpa. If the water pressure is too low, the sprayable distance becomes too short, while if the water pressure is too high, the impact on the injection target becomes too large, which is not preferable.

The average particle size of the ejected droplets is preferably 5 to 300 μm, more preferably 20 to 250 μm and 45 to 210 μm. If the droplets are too small, the directivity will be reduced due to air resistance, which is not preferable. Further, if the droplets are too large, they are greatly affected by gravity and fall off immediately, which is not preferable.

Generally, when droplets are formed by ultrasonic waves, droplets having an average particle size of about 0.3 to 10 μm are generated, but since these droplets are too small, the directivity becomes small. On the other hand, in the present invention, the injection nozzle 16 can inject a droplet of an appropriate size.

The injection nozzle 16 may be installed in the horizontal direction, or may be installed at an angle from the horizontal direction. The direction of the injection nozzle 16 (that is, the injection direction) is appropriately set in relation to the position of the injection nozzle 16 and the object to be injected by adjusting the inclination of the injection member 14 itself, for example.

Branch injection pipes 23 and 24 are connected to the injection nozzle 16, and electrolyzed water is supplied from the electrolyzed water tank 11 via the pipe 21, the pump 12, and the injection pipe 22.

A fan 15 is installed on the rear side of the injection nozzle 16 (that is, the rear side of the injection fixing portion 16A), and can blow air in an injection direction substantially coincide with the central axis of the injection nozzle 16. It should be noted that substantially coincident with the central axis of the injection nozzle 16 means that it is within ± 15 ° from the central axis.

The injection members 14A and 14B are arranged at the same position in the left-right front-rear direction and separated from each other in the up-down direction. For example, the height of the center of the injection member 14A (the center of the injection nozzle 16) is 180 cm, and the height of the center of the injection member 14B is 130 cm.

As described above, the water pressure in the injection pipe 22 is controlled, and the branch injection pipes 23 and 24 also supply the electrolyzed water to the injection nozzle 16 within a predetermined pressure range and inject the electrolyzed water in the injection direction. At this time, the fan 15 can send wind in the injection direction and urge the injected electrolyzed water while spreading it from the opening 17A, and inject the electrolyzed water in a directional and to a certain extent. Can be done. Therefore, the electrolyzed water injection device 1 can efficiently inject the electrolyzed water to the object to be injected even in a space having a large capacity or in an environment where there is some wind.

<Second Embodiment>
Next, the second embodiment will be described. In the electrolyzed water injection device 101 of the second embodiment described with reference to FIG. 3, the point of diluting and injecting the electrolyzed water generated by the electrolysis unit 131 and the three injection members 14 (14A to 14C) Is different from the first embodiment shown in FIGS. 1 and 2. In the second embodiment, the same reference numerals are given to the same parts as those of the first embodiment, and 100 is added to the corresponding parts, and the description of the same parts will be omitted.

As shown in FIG. 3, the electrolyzed water injection device 101 has an auxiliary liquid tank 111 in which an electrolytic auxiliary liquid in which an electrolyte is dissolved is stored. The electrolytic auxiliary solution is not particularly limited, and a known compound that dissolves in water and exhibits properties as an electrolyte can be appropriately used.

For example, when it is desired to generate slightly acidic electrolyzed water as electrolyzed water, a hydrochloric acid aqueous solution or a hydrochloric acid / sodium chloride mixed aqueous solution is preferably used. There is no limitation on the concentration and ratio, and the chlorine concentration is appropriately selected so as to be easy to handle and to have a chlorine concentration according to the application. For example, a mixed aqueous solution of hydrochloric acid / sodium chloride in which 5 to 20% by weight of sodium chloride and 5 to 30% by weight of hydrochloric acid in terms of 10% hydrochloric acid is dissolved, or 5 to 30% by weight of an aqueous hydrochloric acid solution is used.

The pump 12 supplies the sucked electrolytic auxiliary liquid to the electrolysis unit 131 via the injection pipe 22. The electrolysis unit 131 is a one-chamber type electrolytic cell having a cathode electrode and an anode electrode (not shown) in one water bath, electrolyzes an electrolytic auxiliary liquid to generate an electrolyzed water stock solution, and injects pipe 132. To discharge. A known structure can be appropriately used for the one-chamber type electrolytic cell.

A relief valve 125 is attached to the injection pipe 132, and when the water pressure of the injection pipe 132 exceeds a predetermined release pressure, a part of the electrolytic auxiliary liquid is guided to the discharge pipe 126 and discharged from the discharge unit 127. do.

That is, the control unit 120 controls so that the electrolytic auxiliary liquid is supplied from the auxiliary tank 111 to the electrolysis unit 131 at a constant pressure in a constant amount. Then, when the pressure becomes excessive due to a factor such as clogging of the injection nozzle 16, the pressure is adjusted by the relief valve 125.

A diluted water supply unit 133 is connected to the injection pipe 132. The diluted water supply unit 133 is connected to so-called water supply, including public water supply such as water supply and industrial water, and private water supply that pumps water from wells and water tanks to supply water to various places in facilities and factories. The diluted water is supplied to the injection pipe 132 by opening and closing the valve. Further, a dedicated water storage tank may be provided, and diluted water may be supplied to the injection pipe 132 by a pump or gravity.

A pressure relief valve 134 is installed in the branch injection pipe 146. The pressure relief valve 134 is a valve for releasing the residual pressure when the operation of the electrolyzed water injection device 101 is stopped. ..

The injection pipe 132 is branched into three branch injection pipes 144, 145, and 146 by the branch valve 143, and each is connected to the injection member 14. Therefore, the electrolyzed water generated by the electrolysis unit 131 is supplied to the injection member 14 via the injection pipe 132, the branch valve 143, and the branch injection pipes 144, 145, 146, and is injected from the injection nozzle 16.

A sensor 151 using infrared rays or the like is attached to the front side of the housing 2. When the sensor 151 detects an object on the front side, it supplies a detection signal to the control unit 120 (not shown). The control unit 120 drives the pump 12, the electrolysis unit 131, the diluted water supply unit 133, and the fan 15. As a result, electrolyzed water is injected from the injection nozzle 16.

When the control unit 120 injects the electrolyzed water over a predetermined injection time, the control unit 120 stops the pump 12, the electrolysis unit 131, the diluted water supply unit 133, and the fan 15. Further, when the control unit 120 stops the generation and injection of the electrolyzed water, the pressure relief valve 134 is opened, and the pressure relief valve 134 is closed after a predetermined time or before the next generation and injection of the electrolyzed water. .. As a result, the electrolyzed water can be automatically injected only when the object to be injected is detected by the sensor 151.
