Best Mode for Carrying Out the Invention

[0009] Preferred embodiments of the present invention will be described. The chlorine-based substance, ozone, and OH radical in the spray liquid of the present invention may be present in the electrolyzed water obtained by electrolyzing water before spraying. In this case, a spray liquid containing at least two of the chlorine-based substance, ozone, and OH radical can be easily generated, and sterilization and the like can be performed well.

[0010] The spray liquid of the present invention can be sprayed in a mist form. In this case, since the spray liquid floats in a wide space around the sprayed area, sterilization and the like can be performed well.

[0011] Next, Examples 1 to 3 in which an electrolyzed water spraying device for spraying the spray liquid of the present invention is embodied will be described with reference to the drawings. In the description of Example 1, "up and down" refers to the up and down in the state where the base portion 10 of the electrolyzed water spraying device 1 is installed on a horizontal installation surface and the main body portion 50 is connected on the base portion 10 as shown in FIGS. 1 and 2.

[0012] <Example 1> The electrolyzed water spraying device 1 of Example 1 includes a base portion 10, a main body portion 50, and an AC adapter (not shown) as shown in FIGS. 1 to 3. The base portion 10 has an upper surface 20, a lower surface 30, and a side surface 40. As shown in FIG. 5, the outer shape of the base portion 10 in a plan view is a substantially equilateral triangular shape in which each vertex and each side of an equilateral triangle bulge outward and are curved. That is, the outer shapes of the upper surface 20 and the lower surface 30 of the base portion 10 are substantially equilateral triangular shapes in which each vertex and each side of an equilateral triangle bulge outward and are curved in a plan view as shown in FIGS. 3 and 5, and the lower surface 30 is a similar shape slightly larger than the upper surface 20. The side surface 40 of the base portion 10 has an upper end edge continuous with the outer peripheral edge of the upper surface 20 and a lower end edge continuous with the outer peripheral edge of the lower surface 30. The base portion 10 is a cavity surrounded by the upper surface 20, the lower surface 30, and the side surface 40.

[0013] As shown in Fig. 3, the upper surface 20 of the base portion 10 is provided with a convex portion 21 protruding upward at the central portion. This convex portion 21 has a side surface 23 and an upper surface 25. The side surface 23 has three first side surfaces 23A that are planar and extend toward three curved sides at the outer peripheral edge of the upper surface 20 of the base portion 10, and three second side surfaces 23B that are curved surfaces bulging outward and connect the near end sides of adjacent first side surfaces 23A. The upper surface 25 is a flat surface continuous with the upper end edge of the side surface 23. The first terminal 27 for power supply is provided on the convex portion 21 so as to be exposed at the central portion of the upper surface 25. The first terminal 27 is electrically connected to a jack 43 described later. The base portion 10 has a rotationally symmetric shape that is symmetric three times at 120-degree intervals about the first terminal 27 in a plan view.

[0014] The lower surface 30 of the base portion 10 is flat, and as shown in Fig. 2, four disk-shaped elastic cushion members 31 are attached at four locations near the outer peripheral edge and spaced apart. These cushion members 31 have functions of buffering and anti-slip when the base portion 10 is placed on a placement surface.

[0015] As shown in FIG. 5, the side surface 40 of the base portion 10 has three surfaces facing in three directions, and three capacitive switches 41 shown in an annular shape are provided on one of those surfaces. The side surface 40 of the base portion 10 is slightly inclined inward upward. Each switch 41 is a power supply switch that supplies power to the electrolysis portion 90 described later. As shown in FIG. 1, the numbers "1", "3", and "5" are marked on each switch 41, and the character "min" is marked below each switch 41. That is, according to the switch 41 touched by a finger, power is supplied to the electrolysis portion 90 for the time (1 minute, 3 minutes, 5 minutes) of the number marked on that switch 41. As shown in FIG. 1, the base portion 10 is provided with an LED (Light Emitting Diode) 42 that blinks while each switch 41 above is being pressed to supply power to the electrolysis portion 90. The LED 42 is incorporated in the base portion 10, and when it blinks, light can be visually recognized through the side surface 40. As shown in FIG. 5, the side surface 40 of the base portion 10 is formed with a jack 43 into which the connector of the AC adapter is inserted on the side surface 40 located on the opposite side of the side surface 40 where the three switches 41 are provided.

[0016] Inside the base portion 10, a piezoelectric speaker, a circuit board, and wirings (not shown) are housed. The circuit board is formed with each switch 41, a piezoelectric speaker, a power supply circuit connected to the jack 43 and the first terminal 27, and a control circuit, etc. The base portion 10 has the lower end edge of the bottle portion 80 of the main body portion 50 abutted against the upper surface 20 to detachably mount the main body portion 50. When the main body portion 50 is placed on the upper surface 20 of the base portion 10, it becomes possible to supply power to the electrolysis portion 90 disposed in the bottle portion 80 described later.

[0017] As shown in FIGS. 1 to 3, the main body portion 50 has a cap portion 60 and a bottle portion 80. The cap portion 60 is detachably attached to the upper part of the storage portion 86 of the bottle portion 80 so as to close the upper end opening 88A of the storage portion 86 of the bottle portion 80 described later.

[0018] Specifically, to attach the cap portion 60 to the bottle portion 80, first, insert the suction pipe 71 and the pressurizing portion 75 that extend downward from the side surface of the outer shell portion 61 (to be described later) of the cap portion 60 into the storage portion 86 through the upper end opening 88A of the storage portion 86 of the bottle portion 80. In this state, rotate the cap portion 60 clockwise around the central axis of the upper end opening 88A of the storage portion 86 with respect to the bottle portion 80. Then, a convex portion (not shown) provided on the cap portion 60 is guided by a guide projection 89B provided on the outer peripheral surface of the neck portion 88 of the bottle portion 80 (to be described later) and is caught by the locking portion 89A, and the cap portion 60 is attached to the bottle portion 80.

[0019] To remove the cap portion 60 from the bottle portion 80, first, rotate the cap portion 60 counterclockwise around the central axis of the upper end opening 88A of the storage portion 86 with respect to the bottle portion 80. Then, the caught state between the convex portion (not shown) provided on the cap portion 60 and the locking portion 89A provided on the outer peripheral surface of the neck portion 88 of the bottle portion 80 is released. And by pulling out the suction pipe 71 and the pressurizing portion 75 that extend downward from the side surface of the outer shell portion 61 from the upper end opening 88A of the storage portion 86 of the bottle portion 80, the cap portion 60 can be removed from the bottle portion 80.

[0020] As shown in FIGS. 1 to 3, FIGS. 9 to 11, the cap portion 60 includes an outer shell portion 61, a lever 63, and a spraying portion 70. The outer shell portion 61 is a cylindrical shape with its upper surface closed, and the central portion in the vertical direction on the side surface is slightly constricted. The lower end edge of the outer shell portion 61 is circular in a bottom view. The lower end portion of the outer shell portion 61 is formed to be continuous with the side surface of the body portion 87 of the bottle portion 80 and cover the neck portion 88 of the storage portion 86 of the bottle portion 80 when the cap portion 60 is attached to the bottle portion 80. A nozzle 78 (to be described later) for spraying electrolyzed water in a mist form outward is provided at the upper portion of the side surface of the outer shell portion 61.

[0021] On the side surface of the outer shell portion 61, a lever 63 is provided below the nozzle 78. As shown in FIG. 2, the lever 63 moves between a protruding position and a pushed-in position about a rotation axis 63A. The lever 63 at the protruding position protrudes in a state inclined outward from the side surface of the outer shell portion 61 from the upper end portion toward the lower end portion. The lever 63 at the pushed-in position extends in the vertical direction along the side surface of the outer shell portion 61. As shown in FIGS. 1 and 3, on the side surface of the outer shell portion 61, a recess 61A for accommodating a part of the lever 63 at the pushed-in position is formed to extend in the vertical direction. The lever 63 is connected to an elastic member (not shown). The elastic force of this elastic member acts in a direction to move the lever 63 from the pushed-in position to the protruding position.

[0022] As shown in FIGS. 9 to 11, the spraying portion 70 includes a suction pipe 71, a piston portion 72, a communication passage 73, a branch passage 74, a pressurizing portion 75, a pressure regulating valve 76, two check valves (a first check valve 77A and a second check valve 77B), and a nozzle 78. As shown in FIGS. 1 and 3, the suction pipe 71 extends downward from the side surface of the outer shell portion 61 of the cap portion 60. The suction pipe 71 has an upper pipe 71A and a lower pipe 71B. The upper pipe 71A is integrally formed with a cylinder 75A of the pressurizing portion 75 described later. The lower pipe 71B is inserted into and connected to the upper pipe 71A from the lower end opening of the upper pipe 71A and extends downward from the upper pipe 71A. The lower pipe 71B has flexibility, and when the cap portion 60 is attached to the bottle portion 80, it contacts the bottom surface of the storage portion 86 of the bottle portion 80 and is slightly bent.

[0023] As shown in FIGS. 9 to 11, the first check valve 77A is provided in the middle of the suction pipe 71. The first check valve 77A allows the flow on the downstream side in the suction pipe 71 (the flow from the storage portion 86 to the piston portion 72 described later) and blocks the flow on the upstream side in the suction pipe 71 (the flow from the piston portion 72 to the storage portion 86).

[0024] The piston unit 72 has a rod 72A, a piston 72B, and a cylinder 72C. One end of the rod 72A is connected to the piston 72B, and the other end protrudes outside the cylinder 72C and is movable in the axial direction. The piston 72B divides the inside of the cylinder 72C into a rod-side chamber and a counter-rod-side chamber, and is movable in the vertical direction. The downstream end of the suction pipe 71 is connected to the counter-rod-side chamber of the piston unit 72. The other end of the rod 72A protruding outside the cylinder 72C is connected to the lever 63. The rod 72A and the piston 72B move up and down according to the movement of the lever 63. Specifically, when the lever 63 is in the protruding position, the piston 72B is in the uppermost position, and when the lever 63 is in the pushed-in position, the piston 72B is in the lowermost position. That is, when the user of the electrolyzed water spraying device 1 grasps the lever 63 and moves the lever 63 from the protruding position to the pushed-in position, the piston 72B moves from the uppermost position to the lowermost position, and the volume of the counter-rod-side chamber decreases. Due to the elastic force of the elastic member connected to the lever 63, when the lever 63 moves from the pushed-in position to the protruding position, the piston 72B moves from the lowermost position to the uppermost position, and the volume of the counter-rod-side chamber increases.

[0025] The upstream end of the communication passage 73 communicates with the counter-rod-side chamber of the piston unit 72. The downstream end of the communication passage 73 communicates with the nozzle 78. A branch passage 74 branches off in the middle of the communication passage 73. A second check valve 77B is provided in the middle of the communication passage 73 on the upstream side of the branch portion 74A of the branch passage 74. The second check valve 77B allows the flow downstream in the communication passage 73 (the flow from the piston unit 72 to the nozzle 78 and the pressurizing unit 75 described later), and blocks the flow upstream in the communication passage 73 (the flow from the nozzle 78 and the pressurizing unit 75 to the piston unit 72).

[0026] The pressurizing unit 75 has a cylinder 75A, a piston 75B, and a coil spring 75C. The cylinder 75A is cylindrical and extends downward from the outer shell portion 61 of the cap portion 60 (see FIGS. 1 to 3). The piston 75B divides the inside of the cylinder 75A into upper and lower chambers and is movable in the vertical direction. The coil spring 75C is housed in the lower chamber. The elastic force of the coil spring 75C acts in a direction to move the piston 75B upward. The downstream end of the branch passage 74 communicates with the upper chamber.

[0027] A pressure regulating valve 76 is provided in the middle of the communication passage 73 on the downstream side of the branch portion 74A of the branch passage 74. The pressure regulating valve 76 opens to release the communication passage 73 when the pressure in the communication passage 73 upstream of the pressure regulating valve 76 reaches or exceeds a predetermined pressure. The pressure regulating valve 76 closes the communication passage 73 when the pressure in the communication passage 73 upstream of the pressure regulating valve 76 drops below the predetermined pressure. The pressure regulating valve 76 opens to release the communication passage 73 at a pressure lower than the maximum pressure in the pressurizing unit 75.

[0028] The nozzle 78 communicates with the downstream end of the communication passage 73. When the pressure regulating valve 76 opens and electrolyzed water at or above a predetermined pressure flows in, the nozzle 78 sprays the electrolyzed water in a mist form. The electrolyzed water sprayed in a mist form contains fine bubbles. There are two types of fine bubbles: microbubbles and ultra-fine bubbles smaller than them. Microbubbles are bubbles with a diameter of less than 100 μm and not less than 1 μm, and ultra-fine bubbles are bubbles with a diameter of less than 1 μm.

[0029] As shown in FIGS. 1 to 7, the bottle portion 80 includes a bottom portion 81, a storage portion 86, and an electrolysis portion 90. The bottom portion 81 is provided at the lowermost part of the bottle portion 80. The bottom portion 81 has an upper surface 81A, a side surface 81B, and a lower surface 81C. When the bottle portion 80 is placed on the upper surface 20 of the base portion 10, the lower end periphery of the side surface 81B of the bottom portion 81 is formed to be continuous with the outer peripheral edge of the upper surface 20 of the base portion 10. That is, the lower end periphery of the side surface 81B of the bottom portion 81 is in a substantially equilateral triangle shape having the same size as the outer shape of the upper surface 20 of the base portion 10 in a bottom view. The side surface 81B of the bottom portion 81 is slightly inclined inward upward.

[0030] As shown in FIG. 4, the lower surface 81C of the bottom portion 81 is continuous with the inner surface above the lower end periphery of the side surface 81B of the bottom portion 81 and closes the lower part of the bottom portion 81. That is, the lower end portion of the side surface 81B of the bottom portion 81 protrudes downward more than the lower surface 81C. The lower surface 81C of the bottom portion 81 is formed with an inner wall 83 that hangs down more inside than the side surface 81B of the bottom portion 81. When the bottle portion 80 is placed on the upper surface 20 of the base portion 10, the inner wall 83 is slightly outside the side surface 23 of the convex portion 21 provided on the upper surface 20 of the base portion 10 and is along the side surface 23 of the convex portion 21 and is formed to surround the convex portion 21. That is, in a bottom view, the inner wall 83 has three first inner walls 83A that extend linearly and second inner walls 83B that connect the near ends of adjacent first inner walls 83A and curve outward. The lower end edge of the inner wall 83 is located on the same plane as the lower end edge of the side surface 81B of the bottom portion 81. A plurality of ribs 83C are formed on the inner surface of the inner wall 83 to extend in the vertical direction. When the bottle portion 80 is placed on the upper surface 20 of the base portion 10, each rib 83C contacts the side surface 23 of the convex portion 21 provided on the upper surface 20 of the base portion 10 and suppresses the rattling of the main body portion 50 with respect to the base portion 10.

[0031] The lower surface 81C of the bottom portion 81 has a second terminal 85 for power supply exposed at the central portion. The second terminal 85 is electrically connected to the electrolytic portion 90. The second terminal 85 is movable in the vertical direction, and the elastic force of an elastic member (not shown) acts downward. The second terminal 85 protrudes slightly downward from the lower surface 81C of the bottom portion 81 when the bottle portion 80 is not placed on the upper surface 20 of the base portion 10. When the bottle portion 80 is placed on the upper surface 20 of the base portion 10, the second terminal 85 contacts the first terminal 27 and moves upward against the elastic force of the elastic member. Since the elastic force of the elastic member acts downward, the second terminal 85 can surely contact the first terminal 27 and supply power to the electrolytic portion 90 described later.

[0032] The side surface 81B, the lower surface 81C, and the inner wall 83 of the bottom portion 81 are rotationally symmetric shapes that are symmetric three times at 120-degree intervals around the second terminal 85 in a bottom view. Therefore, when placing the bottle portion 80 on the upper surface 20 of the base portion 10, by aligning the lower end periphery of the side surface 81B of the bottom portion 81 with the substantially equilateral triangular outer shape of the upper surface 20 of the base portion 10, while housing the convex portion 21 provided on the upper surface 20 of the base portion 10 in the space surrounded by the inner wall 83 of the lower surface 81C of the bottom portion 81, the bottle portion 80 can be placed on the upper surface 20 of the base portion 10 with the first terminal 27 and the second terminal 85 in contact. That is, the bottle portion 80 can be placed on the upper surface 20 of the base portion 10 regardless of which of the three directions rotated at 120-degree intervals around the vertical line passing through the second terminal 85 it faces.

[0033] As shown in FIGS. 1, 3, and 5, the upper surface 81A of the bottom portion 81 is slightly smaller than the lower surface 81C of the bottom portion 81 and is a substantially equilateral triangular shape similar to the outer shape of the lower surface 81C of the bottom portion 81. The upper surface 81A of the bottom portion 81 is formed at the boundary between the bottom portion 81 and the storage portion 86.

[0034] The bottom part 81 has a cavity in the portion surrounded by the upper surface 81A, the side surface 81B, and the lower surface 81C. Inside the bottom part 81, LEDs (not shown), a circuit board, and wirings are housed. While the LED is supplying power to the electrolytic part 90, it lights up, and its light can pass through the upper surface 81A of the bottom part 81 to illuminate the vicinity of the electrolytic part 90 in the storage part 86. The circuit board is formed with a second terminal 85, a power circuit connected to the electrolytic part 90 and the LED, a control circuit, and the like.

[0035] As shown in FIGS. 1 to 3 and FIG. 5, the storage part 86 is made of a transparent resin and has a body part 87 and a neck part 88. The body part 87 of the storage part 86 is continuously formed from the upper end of the side surface 81B of the bottom part 81. The horizontal cross-sectional shape of the body part 87 of the storage part 86 is a substantially equilateral triangle with the lower end having the same size as the outer shape of the upper surface 81A of the bottom part 81, and it gradually changes into an annular shape upward. On the body part 87 of the storage part 86, three linear marks extending horizontally and the characters "1min", "3min", "5min" are marked beside each mark.

[0036] As shown in FIG. 3, the neck part 88 of the storage part 86 is continuous with the upper end of the body part 87, is cylindrical, and forms an upper end opening 88A of the storage part 86. The neck part 88 of the storage part 86 is formed with a locking part 89A on the outer peripheral surface where a convex part (not shown) of the cap part 60 catches, and a guiding protrusion 89B for guiding the convex part to the locking part 89A. As shown in FIG. 7, the neck part 88 of the storage part 86 is formed with a groove part 88B extending vertically in the opposing parts of the inner peripheral surface. The groove part 88B is an exhaust path for exhausting the gas generated in the electrolytic part 90 to the outside when the cap part 60 is attached to the bottle part 80.

[0037] As shown in FIGS. 1, 3, and 5, the electrolysis section 90 is provided in a state of rising on the upper surface 81A of the bottom section 81. The electrolysis section 90 is located within the storage section 86. As shown in FIG. 6, the electrolysis section 90 includes a titanium anode 90A, a stainless-steel cathode 90B having a plurality of openings formed therein, and a pair of spacers 90C. The anode 90A has a substantially square shape on both its front and back surfaces, and is arranged such that the front and back surfaces rise vertically with one side end face facing the upper surface 81A of the bottom section 81. The anode 90A has a connection portion 90X protruding downward from the lower side in a state where the front and back surfaces are arranged to rise. The connection portion 90X of the anode 90A is connected to the positive electrode side of the power circuit within the bottom section 81. The anode 90A is formed by performing annealing treatment after forming titanium, and performing a plurality of coating and sintering processes. Among the plurality of coatings, ruthenium and iridium are mixed in a ratio in one or more coatings.

[0038] The cathode 90B is formed by bending a stainless-steel flat plate, and has a substantially square first surface 90F and second surface 90S that are slightly larger than the front and back surfaces of the anode 90A, and a third surface 90T that connects one side of the first surface 90F and one side of the second surface 90S and has a width larger than the thickness of the anode 90A. The cathode 90B has a connection portion 90Y protruding downward from the lower side of the second surface 90S in a state where the anode 90A is arranged between the first surface 90F and the second surface 90S. The connection portion 90Y of the cathode 90B is connected to the negative electrode side of the power circuit within the bottom section 81.

[0039] Each spacer 90C is attached at a position separated in the vertical direction of the anode 90A so as to go around the anode 90A in the horizontal direction. Each spacer 90C prevents contact between the anode 90A and the cathode 90B when the anode 90A is arranged between the first surface 90F and the second surface 90S of the cathode 90B. The cathode 90B is supported by a support portion 91 such that the anode 90A is arranged between the first surface 90F and the second surface 90S.

[0040] Next, the usage method of this electrolyzed water spraying device 1 will be described. <Connection of power supply> Insert the connector of the AC adapter into the jack 43 of the base unit 10, plug the power plug of the AC adapter into the outlet to connect the power supply. Install the base unit 10 on a horizontal installation surface.

[0041] <Storage of tap water into the storage part 86 of the bottle part 80> First, rotate the cap part 60 counterclockwise around the central axis of the upper end opening 88A of the storage part 86 with respect to the bottle part 80 to remove the cap part 60 from the bottle part 80. Next, pour tap water into the upper end opening 88A of the storage part 86 and store the tap water until the water surface rises to any one of the three marks marked on the body part 87 of the storage part 86 of the bottle part 80.

[0042] Next, insert the suction pipe 71 and the pressurizing part 75 extending downward from the side surface of the outer shell part 61 of the cap part 60 into the storage part 86 through the upper end opening 88A of the storage part 86 of the bottle part 80, and rotate the cap part 60 clockwise around the central axis of the upper end opening 88A of the storage part 86 with respect to the bottle part 80 to attach the cap part 60 to the bottle part 80. At this time, the suction pipe 71 is in a state of contacting the bottom surface of the storage part 86 and being slightly bent.

[0043] <Generation of electrolyzed water> First, align the substantially equilateral triangular upper surface 20 of the base unit 10 with the substantially equilateral triangular lower end periphery of the side surface 81B of the bottom part 81, and place the main body part 50 on the upper surface 20 of the base unit 10. At this time, while the convex part 21 provided on the upper surface 20 of the base unit 10 is housed in the space surrounded by the inner wall 83 of the lower surface 81C of the bottom part 81, a plurality of ribs 83C formed on the inner surface of the inner wall 83 contact the side surface 23 of the convex part 21 provided on the upper surface 20 of the base unit 10, and the rattling of the main body part 50 with respect to the base unit 10 is suppressed. Also, the first terminal 27 of the base unit 10 and the second terminal 85 of the bottom part 81 of the main body part 50 come into contact, and the electrolysis part 90 can be powered.

[0044] Next, touch with your finger the switch 41 provided on the side surface 40 of the base portion 10 according to the amount of water stored in the storage portion 86. That is, by touching with your finger the switch 41 marked with the same time as the characters ("1 min", "3 min", "5 min") written beside the mark at the same height as the water surface, a voltage of 24 V is applied between the anode 90A and the cathode 90B for that period of time. In this way, the tap water stored in the storage portion 86 of the bottle portion 80 is electrolyzed to generate electrolyzed water. Hypochlorous acid, hypochlorite ions, chlorate ions, ozone, OH radicals, etc. were detected from the generated electrolyzed water. Hypochlorous acid, hypochlorite ions, and chlorate ions are chlorine-based substances.

[0045] By varying the power supply time to the electrolysis portion 90 according to the amount of water stored in the storage portion 86, electrolyzed water having an appropriate concentration can be generated. Also, while power is being supplied to the electrolysis portion 90, the LED 42 provided above the switch 41 touched with the finger blinks, and light can be visually recognized through the side surface 40 of the base portion 10, and the LED that illuminates the vicinity of the electrolysis portion 90 in the storage portion 86 lights up. For this reason, it is possible to recognize that electrolyzed water is being generated. Also, the surplus gas generated in the electrolysis portion 90 is exhausted to the outside of the bottle portion 80 through the groove portion 88B formed on the inner peripheral surface of the neck portion 88 of the storage portion 86.

[0046] When the power supply time of the pressed switch 41 elapses and the generation of electrolyzed water is completed, a "pip" sound rings from the piezoelectric speaker in the base portion 10, the LED that illuminates the vicinity of the electrolysis portion 90 goes out, and the LED 42 provided above the switch 41 changes from blinking to lighting and goes out after a predetermined time (about 15 minutes) has elapsed. For this reason, it is possible to recognize that the generation of electrolyzed water is completed. Also, since the ozone concentration in the generated electrolyzed water gradually decreases with the passage of time, the spraying of the electrolyzed water can be completed using as a guide the time that the LED 42 above the switch 41 is lit.

[0047] <Spraying of mist-like electrolyzed water> Lift and separate the main body 50 from the base 10. By the user of the electrolyzed water spraying device 1 grasping the lever 63 of the cap part 60, the lever 63 moves from the protruding position to the pushed-in position, and the lever 63 moves from the pushed-in position to the protruding position due to the elastic force of the elastic member connected to the lever 63 are repeated. Then, mist-like electrolyzed water is continuously sprayed from the nozzle 78 of the main body 50. The electrolyzed water sprayed in a mist form is the spraying liquid.

[0048] Specifically, when the user grasps the lever 63 and moves the lever 63 from the protruding position to the pushed-in position, the volume of the anti-rod side chamber of the piston part 72 decreases, and the electrolyzed water temporarily stored in the anti-rod side chamber flows to the nozzle 78 side through the communication passage 73 and also flows into the pressurizing part 75 through the communication passage 73 and the branch passage 74. The electrolyzed water flowing to the nozzle 78 side is sprayed in a mist form from the nozzle 78 through a pressure regulating valve 76 that opens when the pressure reaches a predetermined pressure or higher. Also, the electrolyzed water flowing into the pressurizing part 75 pushes down the piston 72B and stores the electrolyzed water in the upper chamber of the pressurizing part 75 in a pressurized state. In the situation where the lever 63 is moved from the protruding position to the pushed-in position, the flow to the upstream side in the suction pipe 71 (the flow from the piston part 72 to the storage part 86) is blocked by the first check valve 77A provided in the middle of the upper pipe 71A of the suction pipe 71.

[0049] When the user weakens the force of gripping the lever 63 and the lever 63 moves from the pushed-in position to the protruding position by the elastic force of the elastic member connected to the lever 63, the electrolyzed water stops flowing into the pressurizing section 75, and the piston 72B moves upward by the elastic force of the coil spring 75C housed in the lower chamber of the pressurizing section 75. The electrolyzed water temporarily stored in a pressurized state in the upper chamber of the pressurizing section 75 flows toward the nozzle 78 side through the branch path 74 and the communication path 73. Since the pressure regulating valve 76 opens the communication path 73 by opening at a pressure lower than the maximum pressure in the pressurizing section 75, the electrolyzed water flowing from the pressurizing section 75 toward the nozzle 78 side is sprayed in a mist form from the nozzle 78 through the pressure regulating valve 76. Thus, this electrolyzed water spraying device 1 can spray the electrolyzed water in a mist form from the nozzle 78 not only when the lever 63 moves from the protruding position to the pushed-in position but also when the lever 63 moves from the pushed-in position to the protruding position.

[0050] When the lever 63 moves from the pushed-in position to the protruding position, the volume of the anti-rod side chamber of the piston portion 72 increases, and the electrolyzed water flows into the anti-rod side chamber from the storage portion 86 through the suction pipe 71 and is stored in the anti-rod side chamber. In the situation where the lever 63 moves from the pushed-in position to the protruding position, the flow upstream in the communication path 73 (the flow from the nozzle 78 and the pressurizing section 75 to the piston portion 72) is blocked by the second check valve 77B provided in the middle of the communication path 73 on the upstream side of the branch portion 74A of the branch path 74.

[0051] Next, the generation amount of ultra-fine bubbles and the like in this electrolyzed water spraying device 1 will be described. Tap water in Tokyo was stored up to the position of the mark written beside the character "5min" in the storage portion 86 of the bottle portion 80 of this electrolyzed water spraying device 1. The switch 41 with the number "5" written on the base portion 10 was touched with a finger, and power was supplied to the electrolyzing section 90 for 5 minutes to generate electrolyzed water, and the generated electrolyzed water was sprayed in a mist form from the nozzle 78. Table 1 shows the generation amount and generation amount ratio of ultra-fine bubbles at this time.

[0052]

Table 1

[0053] The "blank water" and "measured value" in Table 1 are the number of particles less than 1 μm per 1 mL measured by the NanoSite NS300 manufactured by Malvern. The "blank water" is the tap water stored in the storage unit 86 and is the value measured before power is supplied to the electrolysis unit 90. The "measured value" is the value obtained by measuring the electrolyzed water stored in the storage unit 86 after power is supplied to the electrolysis unit 90 for electrolysis, and the electrolyzed water sprayed in a mist form from the nozzle 78. It is considered that the "blank water" and "measured value" include the number of ultrafine bubbles in tap water and electrolyzed water, and the number of fine dust less than 1 μm in tap water and electrolyzed water. Therefore, the "ultrafine bubble generation amount (measured value - blank water)" is considered to indicate the number of ultrafine bubbles increased by electrolyzing tap water by supplying power to the electrolysis unit 90, and further the number of ultrafine bubbles increased by spraying in a mist form from the nozzle 78. From the "generation amount ratio of blank water and measured value" in Table 1, it can be seen that in this electrolyzed water spraying device 1, compared with the increase in ultrafine bubbles by supplying power to the electrolysis unit 90 for electrolysis, the increase in ultrafine bubbles by spraying in a mist form from the nozzle 78 is larger.

[0054] Next, the sterilization and virus removal effects of the electrolyzed water sprayed in a mist form from the nozzle 78 of this electrolyzed water spraying device 1 will be described.

[0055] (1) Sterilization effect on Escherichia coli and Staphylococcus aureus (Test 1) After culturing Escherichia coli (Escherichia coli, JCM5491), it was adjusted to 10 7 cfu / mL with sterilized water and used as the test bacterial solution. Similarly, after culturing Staphylococcus aureus (Staphylococcus aureus, NBRC12732), it was adjusted to 10 7 cfu / mL with sterilized water and used as the test bacterial solution.

[0056] After dropping 400 μL of the test bacterial solution into a plastic petri dish, six types of test water were mixed in amounts of 1 mL, 2 mL, and 3 mL each according to the spraying conditions, and after 5 minutes, standard agar medium was added to stop the reaction (n = 2). The six types of test water were obtained by storing either tap water collected in Tokyo or tap water collected in Nagoya in the storage section 86 of the bottle section 80 of this electrolyzed water spraying device 1, and setting the power supply time to the electrolysis section 90 to 0 minutes, 2 minutes, or 4 minutes. After the reaction was stopped, the mixture was cultured at 35°C for 48 hours, and the number of bacteria detected in each petri dish was counted. The test results for Escherichia coli are shown in Table 2, and the test results for Staphylococcus aureus are shown in Table 3.

[0057]

Table 2

[0058]

Table 3

[0059] As shown in Table 2 and Table 3, the electrolyzed water sprayed in a mist form from the nozzle 78 of this electrolyzed water spraying device 1 has a bactericidal effect against Escherichia coli and Staphylococcus aureus.

[0060] (2) Bactericidal effect against Escherichia coli and Staphylococcus aureus (Test 2) Regarding the sprayed liquid sprayed by the electrolyzed water spraying device 1, based on Appendix C "Test Method for Bactericidal Performance" of JIS B 8701, Escherichia coli (Escherichia coli, NBRC3972; number of subcultures 5 times) and Staphylococcus aureus (Staphylococcus aureus, NBRC12732; number of subcultures 5 times) were used as test bacteria to evaluate the "bactericidal performance".

[0061] In evaluating the bactericidal effect of the electrolyzed water sprayed in a mist form from the nozzle 78 of the electrolyzed water spraying device 1, the reason for evaluating the "bactericidal performance" based on Appendix C "Test Method for Bactericidal Performance" of JIS B 8701 is as follows: 1. and 2. shown below. 1. There is no standard for evaluating the sterilization effect of the electrolyzed water sprayed in the form of mist, such as the sprayed liquid generated by the electrolyzed water spraying device 1. 2. If the test results based on the "Sterilization Performance Test Method" in Appendix C of JIS B 8701 show that there is sterilization performance, it can be evaluated that there is a sterilization effect.

[0062] The "sterilization test" was carried out as described below. First, the specimens (test water and control) directly sprayed from the nozzle 78 of the electrolyzed water spraying device 1 into a sterilized glass container were collected. 9.8 mL was separated and obtained from each of the collected specimens, 0.1 mL of the test bacterial solution was added, and it was stirred with a vortex mixer for 30 seconds. After stirring, 0.1 mL of 3% sodium thiosulfate was added and stirred for 30 seconds to stop the reaction. After the reaction stopped, 1 mL was collected, mixed and diluted on a standard agar medium, and cultured at 35 ± 1 °C for 48 hours. The sterilization test of the test water was carried out 3 times repeatedly.

[0063] The test water of the specimen was the tap water collected in Nagoya City stored in the storage part 86 of the bottle part 80 of the electrolyzed water spraying device 1. After 240 mL of tap water was stored and power was supplied to the electrolysis part 90 for 5 minutes, the electrolyzed water stored in the storage part 86 for 12 hours was sprayed in the form of mist from the nozzle 78 of the main body part 50. Also, as a control, the sterilized water of the tap water collected in Nagoya City stored in the storage part 86 of the bottle part 80 of the electrolyzed water spraying device 1 and sprayed in the form of mist from the nozzle 78 of the main body part 50 was used as the control. Also, the test bacterial solution was adjusted so that the number of bacteria of each test bacterium was 2.0×10 8 ~1.0×10 9 CFU / mL.

[0064] The number of colonies appearing in each medium was counted, and the "sterilization performance" in the "Sterilization Performance Test Method" in Appendix C of JIS B 8701 was calculated by the following formula 1 from the number of bacteria in the control and the average remaining number of bacteria in the test water. The calculated value is rounded down to the second digit after the decimal point and displayed with one digit after the decimal point. If no colony form is recognized in any medium, the detected number of bacteria is set to 1×10 0 CFU / mL, and the measurement result is regarded as "not detected".

[0065] [Number]

[0066] The results of the "sterilization performance test" for each specimen are shown in Table 4. The sterilization performance of the test water met the standard of 6.0 or higher for the two test bacterial species, and was judged to have "sterilization performance" according to the judgment criteria of Appendix C, "Sterilization Performance Test Method" of JIS B 8701. That is, the electrolyzed water generated by the electrolyzed water spraying device 1 maintained the sterilization effect even 12 hours after generation.

[0067] [Table 4]

[0068] (3) Removal effect on influenza A virus and feline calicivirus A liquid of influenza A virus (Influenza A virus, A / PR / 8 / 34, ATCC VR-1469) was dropped (2 μL × 10 places = 20 μL) onto a glass plate (5 cm × 5 cm) and dried in a desiccator at room temperature to obtain a test carrier. Similarly, a liquid of feline calicivirus (Feline calicivirus, F-9, ATCC VR-782) was dropped (2 μL × 10 places = 20 μL) onto a glass plate (5 cm × 5 cm) and dried in a desiccator at room temperature to obtain a test carrier.

[0069] The electrolyzed water generated by the electrolyzed water spraying device 1 was sprayed 1 to 3 times on the test carrier from a distance of about 10 cm. The electrolyzed water was generated by storing tap water in the storage part 86 of the bottle part 80 of the electrolyzed water spraying device 1 and supplying power to the electrolysis part 90 for 5 minutes. After standing for 5 minutes, the virus was washed out from the test carrier with the washing liquid, and the infectious titer of the washing liquid was measured by the plaque method. The test results for influenza A virus are shown in Table 5, and the test results for feline calicivirus are shown in Table 6.

[0070] [Table 5]

[0071]

Table 6

[0072] As shown in Table 5 and Table 6, it can be seen that the electrolyzed water sprayed in a mist form from the nozzle 78 of this electrolyzed water spraying device 1 has a removal effect on type A influenza virus and feline calicivirus.

[0073] As described above, the spraying liquid of Example 1 contains chlorine-based substances, ozone, and OH radicals and is sprayed. Therefore, this spraying liquid can perform sterilization and virus removal well.

[0074] The chlorine-based substances, ozone, and OH radicals in this spraying liquid are present in the electrolyzed water obtained by electrolyzing water before spraying. In this way, the spraying liquid can be easily generated.

[0075] <Example 2> As shown in FIGS. 12 and 13, the electrolyzed water spraying devices 2 and 3 of Example 2 are of a permanent installation type. The spraying liquid sprayed from the electrolyzed water spraying devices 2 and 3 is electrolyzed water obtained by electrolyzing water and contains at least two of chlorine-based substances, ozone, and OH radicals.

[0076] A plurality of spray nozzles 101 are attached along the eaves 110A of the roof 110 of a building provided outdoors for the electrolyzed water spraying device 2. A plurality of spray nozzles 102 are attached to the upper part of the ceiling part 12A of the entrance 120 of the building and the wall part 120B continuous with the ceiling part for the electrolyzed water spraying device 3.

[0077] In the electrolyzed water spraying devices 2 and 3, flow paths (not shown) for supplying electrolyzed water are communicated with the respective spray nozzles 101 and 102. In the electrolyzed water spraying devices 2 and 3, the electrolyzed water is sprayed in a mist form from each of the spray nozzles 101 and 102. As a method of spraying the electrolyzed water in a mist form from each of the spray nozzles 101 and 102, any one of a method of pressurizing the electrolyzed water and spraying it in a mist form, a method of spraying the electrolyzed water in a mist form by compressed air, and a method of generating mist by ultrasonic waves and spraying it in a mist form can be appropriately used.

[0078] In the electrolyzed water spraying devices 2 and 3, the electrolyzed water may be constantly sprayed in a mist form from each of the spray nozzles 101 and 102. Further, in the electrolyzed water spraying devices 2 and 3, when a human body detection sensor is provided and a person passing through the eaves 110A under the roof 110 or the entrance 120 is detected, the electrolyzed water may be sprayed in a mist form from each of the spray nozzles 101 and 102. Furthermore, in the electrolyzed water spraying devices 2 and 3, the electrolyzed water may be sprayed in a mist form from each of the spray nozzles 101 and 102 at a predetermined time or at predetermined time intervals.

[0079] In the electrolyzed water spraying devices 2 and 3, when they are attached to an outdoor area or a building facing the outdoors, in order to spray the electrolyzed water in a mist form, the mist-like electrolyzed water floats in a wide surrounding space where the electrolyzed water is sprayed, and it can be sterilized well and is also effective as a measure against heat stroke.

[0080] <Example 3> As shown in FIG. 14, the electrolyzed water spraying device 4 of Example 3 is a mobile type. The spraying liquid sprayed from the electrolyzed water spraying device 4 is electrolyzed water obtained by electrolyzing water and contains at least two kinds of chlorine-based substances, ozone, and OH radicals.

[0081] The electrolyzed water spraying device 4 includes a main body 201 and a pedestal 202 that supports the main body 201. The main body 201 has a substantially cylindrical shape, and a plurality of spray openings 201A for spraying electrolyzed water in a mist form are formed on a substantially annular front end surface. Each spray opening 201A communicates with a flow path (not shown) for supplying electrolyzed water. As a method of spraying electrolyzed water in a mist form from the spray opening 201A, any of a method of pressurizing electrolyzed water and spraying it in a mist form, a method of spraying electrolyzed water in a mist form by compressed air, and a method of generating mist by ultrasonic waves and spraying it in a mist form can be appropriately used.

[0082] The main body 201 ejects air from a central opening 201B forward along the central axis. For this reason, in the electrolyzed water spraying device 4, the electrolyzed water sprayed in a mist form from the spray opening 201A rides on the air ejected from the central opening 201B of the main body 201 and reaches far away. As a result, the mist-like electrolyzed water floats in a wide surrounding space where the electrolyzed water is sprayed, and it can be sterilized well and is also effective as a countermeasure against heat stroke.

[0083] The main body 201 is pivotally supported by the pedestal 202 such that the angle formed by the central axis and the horizontal plane can be freely changed. The main body 201 can be fixed to the pedestal 202 at an arbitrary angle formed by the central axis and the horizontal plane. Therefore, by arranging a plurality of electrolyzed water spraying devices 4 with different angles formed by the central axis of the main body 201 and the horizontal plane side by side, a wider space can be sterilized.

[0084] A plurality of wheels (not shown) are attached to the lower end of the pedestal 202. The pedestal 202 is provided with a locking mechanism for locking the rotation of the wheels. The electrolyzed water spraying device 4 can be easily moved by the wheels by releasing the locking mechanism. For this reason, the electrolyzed water spraying device 4 can be easily moved and installed at an event venue or the like.

[0085] The present invention is not limited to the embodiments 1 to 3 described with the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention. (1) In Example 1, a base portion was provided separately from the main body portion. However, the base portion may not be provided, and a jack for directly inserting the connector of the AC adapter into the main body portion may be provided to supply power to the electrolysis portion. (2) In Example 1, three switches were provided on the side surface of the base portion. However, the number of switches is not limited to three. (3) In Example 1, corresponding to "1 min", "3 min", and "5 min" described in the storage portion, switches marked with "1", "3", and "5" were provided on the side surface of the base portion to supply power to the electrolysis portion for a certain time. However, the power supply time of the electrolysis portion is only an example, and other times may also be used. (4) In Example 1, the spraying portion includes a piston portion, a communication passage, a branch passage, a pressurizing portion, a pressure regulating valve, two check valves (a first check valve and a second check valve), and a nozzle, and a water circuit in which they are communicated with each other is formed. However, this water circuit is only an example, and other water circuits may also be used. (5) In Example 1, hypochlorous acid, hypochlorite ions, chlorate ions, ozone, OH radicals, etc. were detected from the electrolyzed water generated by supplying power to the electrolysis portion and electrolyzing the tap water stored in the storage portion of the bottle portion. However, at least any two of these may be present in the electrolyzed water obtained by electrolyzing tap water. (6) In Example 1, the generation amount of ultra-fine bubbles, etc. was confirmed. However, the electrolyzed water sprayed in a mist form may contain microbubbles. (7) In Example 2, a plurality of spray nozzles were attached under the eaves of the roof or at the entrance and exit of the building. However, the electrolyzed water spraying device may be installed in buildings such as agricultural greenhouses and livestock houses. (8) In Examples 2 and 3, the electrolyzed water to be sprayed may contain fine bubbles.
