Description

Ozone water dispersing device

technical field

The invention relates to an ozone water dispersing device for dispersing ozone water in the form of rain and mist.

Background technique

For example, Patent Document 1 describes an ozone sprayer which generates ozone by electrolyzing water stored in a container and sprays ozone water containing the generated ozone in water.

The ozone nebulizer of Patent Document 1 includes: a container that accommodates raw material water; a head part that is attached to the container; a first pipe and a second pipe that communicate the head part and the container; and an electrolytic cell that is attached to the second pipe. A nozzle, trigger and piston-cylinder mechanism are provided in the head. The electrolytic cell has an anode and a cathode inside the electrolytic cell, and the electrolytic cell is arranged at the bottom of the container and is submerged when the raw material water is stored in the container. When the trigger is operated, a voltage is applied between the anode and the cathode of the electrolytic cell, and the raw water is electrolyzed to generate ozone water. The generated ozone water is sent to the nozzle through the piston cylinder mechanism, and the ozone water is sprayed from the nozzle.

In the above-mentioned ozone sprayer, if the water in the container is not reduced to an amount that needs to be replenished, the electrolytic cell is in a state of being immersed in water. Therefore, it is difficult to energize between the anode and the cathode in a state where no water exists in the electrolytic cell.

On the other hand, depending on the structure of the ozone atomizer, the electrolytic cell may be arranged in a position where it is difficult to be submerged by the water stored in the container. In the case of adopting such a structure, if electricity is supplied between the anode and the cathode in a state where no water exists in the electrolytic cell, there is a possibility that the anode and the cathode may be damaged.

SUMMARY OF THE INVENTION

The problem to be solved by the invention

The present invention has been made in view of this problem, and an object of the present invention is to provide an ozone water distributing device in which the anode and the cathode are less likely to be damaged when the structure is adopted to generate ozone water using an electrolysis unit having an anode and a cathode.

solution to the problem

The ozone water dispersing device according to the main aspect of the present invention is provided with: a discharge part for discharging ozone water containing ozone in water in the form of rain or mist; a water storage part for storing water; a channel for electrolyzing the water flowing in the flow channel to generate ozone water; a water supply device for sending the water drawn from the water storage part to the discharge part through the flow channel; and a control part for controlling the electrolysis part and the water delivery device. Here, the control unit energizes the anode and the cathode after a predetermined time has elapsed since the water supply device was started to operate.

According to the above-described configuration, the water drawn from the water storage portion can be fed into the flow path before the anode and the cathode are energized. This makes it difficult to energize the anode and the cathode in a state where no water exists in the flow path, and it is difficult to damage these electrodes. The ozone water spraying device of the present aspect may further include a detection unit for detecting whether or not water exists in the flow path. In this case, the control unit performs a predetermined abnormality process based on the absence of water in the flow path after the predetermined time has elapsed.

For example, the detection unit may detect the current when the anode and the cathode are energized. In this case, when the current value detected by the detection unit is smaller than a threshold value, the control unit determines that water does not exist in the flow path.

According to the above-mentioned structure, when the water is not normally supplied to the electrolysis unit, the ozone water distributing device can avoid such an abnormal state from being ignored.

In the case of adopting the above-mentioned configuration, a notification unit may be further provided. In this case, the control unit causes the notification unit to perform notification as the abnormal processing.

By adopting such a configuration, the user can grasp that the water is not being supplied to the electrolysis unit normally, and can appropriately perform countermeasures such as replenishment of water when the water storage unit is empty of water.

In the case of adopting the above-mentioned structure, an operation part that is operated when ozone is dispersed may be further provided. In this case, as the abnormality processing, even if the operation unit is operated, the control unit does not perform the operation of the water supply device and the energization of the anode and the cathode.

When such a structure is adopted, it is possible to prevent the water supply device from operating in vain, and it is more difficult to damage the anode and the cathode.

FIG. 4( a ) is a perspective view of the electrolysis unit 23 , and FIG. 4( b ) is a cross-sectional view of the electrolysis unit 23 taken along the line AA′ of FIG. 4( a ). FIG. 5( a ) is a front view of the ozone electrode unit 110 fixed to the sealing body 120 , and FIG. 5( b ) is a cross-sectional view of the anode 111 covered with the ion exchange membrane 113 .

Referring to FIGS. 4( a ) to 5 ( b ), the electrolysis unit 23 includes an ozone electrode unit 110 , a sealing body 120 , and a case body 130 .

The ozone electrode unit 110 includes: a round rod-shaped anode 111 ; a linear cathode 112 , which is spirally wound around the outer circumference of the anode 111 ; The ion exchange membrane 113 is attached to the outer peripheral surface of the anode 111 and covers the outer peripheral surface.

The base end portion of the ozone electrode unit 110 is connected to the cylindrical holder 140 . The anode lead terminal 141 and the cathode lead terminal 142 extend upward from the holder 140 . Inside the holder 140 , the anode 111 is connected to the anode lead terminal 141 , and the cathode 112 is connected to the cathode lead terminal 142 .

The sealing body 120 includes a cylindrical threaded portion 121 formed with an external thread, and a hexagonal prism-shaped head portion 122 . An O-ring 123 made of rubber or the like is attached to the root of the screw portion 121 . The screw portion 121 is provided with a cylindrical recessed portion 124 , and the head portion 122 is provided with two through

holes

125 and 126 connected to the recessed portion 124 . The holder 140 is inserted into the concave portion 124 to be fixed, and the anode lead terminal 141 and the cathode lead terminal 142 protrude above the head portion 122 through the corresponding through

holes

125 and 126, respectively. In this way, the ozone electrode unit 110 is covered with the ion exchange membrane 113 and the base end portion of the anode 111 on which the cathode 112 is wound is fixed to the sealing body 120 via the holder 140 .

The case body 130 has a cylindrical shape with one end closed and the other end open. The ozone electrode unit 110 is accommodated in the case body 130 , and the open end of the case body 130 is blocked by the screw portion 121 of the sealing body 120 . A female screw portion is formed on the inner wall surface of the case body 130 corresponding to the screw portion 121, and the female screw portion meshes with the male screw portion. The sealing body 120 and the box body 130 are water-sealed by the O-ring 123 .

The part other than the part blocked by the screw part 121 of the sealing body 120 in the inside of the case body 130 becomes the flow path 131 . The flow path 131 becomes longer in the direction in which the anode 111 extends. The ozone electrode unit 110 is arranged in the center of the flow channel 131 . A concave portion 132 is provided at the position of the center of the flow path 131 at the closed end portion of the case body 130 . The distal end portion of the anode 111 is fitted into the concave portion 132 and held by the concave portion 132 . Thereby, the ozone electrode unit 110 , which is the anode 111 , is held in a state of being supported at both ends by the sealing body 120 and the concave portion 132 , and is in a state of being straight with respect to the flow path 131 .

The inner diameter and outer diameter of the other parts of the case body 130 constituting the flow path 131 are smaller than the inner diameter and outer diameter of the part blocked by the screw portion 121 of the sealing body 120 . Thereby, the diameter of the flow path 131 can be kept small, and the flow rate of the water flowing in the flow path 131 can be reduced. For example, when the radius R1 of the ozone electrode unit 110 is set to be about 4.0 mm, the inner diameter of the other part, that is, the radius R2 of the flow path 131 can be set to 5.0 mm.

The inflow port 133 is formed in the position of the front end part of the ozone electrode unit 110 in the peripheral surface part of the case 130, and the outflow port 134 is formed in the position of the base end part of the ozone electrode unit 110. The inflow port 133 and the outflow port 134 open in a second direction orthogonal to the first direction in which the anode 111 locks extend. In the first direction, the flow path 131 becomes longer, and the case 130 becomes longer. Further, the inflow port 133 and the outflow port 134 protrude in the second direction from the peripheral surface of the case body 130 . The diameters of the inflow port 133 and the outflow port 134 are set to be smaller than the diameter of the flow path 131 . The diameters of the inflow port 133 and the outflow port 134 may be substantially equal to the diameter of the flow path 131 .

The discharge pipe 25 to the pump 22 is connected to the inflow port 133 . The common pipe 31 to the rain discharge part 40 and the mist discharge part 50 is connected to the outflow port 134 .

The electrolysis part 23 is arranged in the casing 10 with the vertical direction of the ozone sprayer 1 as the longitudinal direction, that is, in the casing 10 in the longitudinal direction.

In the production unit 20 , when the pump 22 operates, the water in the container 21 is sucked from the water suction port 241 , and sent to the electrolysis unit 23 through the water suction pipe 24 , the pump 22 , and the discharge pipe 25 . In the electrolysis unit 23 , electricity is supplied between the anode 111 and the cathode 112 . The water flowing into the flow path 131 from the inflow port 133 hits the wall surface of the flow path 131 , changes direction at a substantially right angle, and flows into the flow path 131 so as to follow the ozone electrode unit 110 . A part of the water flowing through the flow path 131 contacts the ion exchange membrane 113 between the anode 111 and the cathode 112, and the contacted water is electrolyzed to generate ozone. The generated ozone is dissolved in water to generate ozone water. At this time, in the flow path 131, when the water flowing in from the inflow port 133 hits the wall surface and changes direction at a substantially right angle, the water flow is disturbed and a turbulent flow occurs. As a result, water easily reaches the concave portion of the spirally wound cathode 112 , and the water easily comes into contact with the ion exchange membrane 113 , thereby improving the ozone generation efficiency. In addition, the generated ozone is easily miniaturized due to turbulent flow, and is easily dissolved in water. Therefore, ozone water with a high ozone concentration is easily produced.

The ozone water flowing through the flow path 131 encounters the sealing body 120 , changes direction at a substantially right angle, and flows out from the outflow port 134 .

2 , the water guide 30 includes a common pipe 31 , a rain pipe 32 , a mist pipe 33 , a rain valve 34 , and a mist valve 35 .

The switching portion 36 is arranged in the head portion 10 c of the casing 10 .

When the pump 22 and the electrolysis unit 23 are not in operation, the rain valve 34 and the mist valve 35 are closed, and when the pump 22 and the electrolysis unit 23 are in operation, one valve is opened. The ozone water that flows out from the electrolysis unit 23, which is the generation part 20, and flows through the common pipe 31 by the water supply pressure of the pump 22, is sent to the rain discharge part 40 through the rain pipe 32 when the rain valve 34 is opened, and is sent to the rain discharge part 40 for mist.

The control part 81 determines whether the 2nd time (for example, 0.5 second) has passed since the pump 22 started operating (S204). Usually, until the second time elapses, the water drawn from the container 21 reaches the electrolysis unit 23 , the water flows through the flow path 131 , and the anode 111 and the cathode 112 are immersed in the water existing in the flow path 131 .

When the second time has elapsed ( S204 : YES), the control unit 81 operates the electrolysis unit 23 , that is, energizes the anode 111 and the cathode 112 ( S205 ). Then, the control unit 81 detects the current flowing between the anode 111 and the cathode 112 via the current detection unit 89 ( S206 ), and determines whether the detected current value is larger than a preset threshold value ( S207 ). When water exists in the flow path 131, the current flows well between the anode 111 and the cathode 112, and the detected current value is larger than the threshold value.

When the detected current value is larger than the threshold value ( S207 : YES), the control unit 81 waits for the elapse of a third time (for example, 1.5 seconds) after the electrolysis unit 23 is operated ( S208 ). When the pump 22 and the electrolysis unit 23 operate, the ozone water generated by the electrolysis unit 23 is sent to the rain discharge unit 40 , and the rain-like ozone water is discharged from the discharge port 14 of the casing 10 .

When the third time has elapsed ( S208 : YES), if the operation button 61 is not continuously pressed ( S209 : NO), the control unit 81 causes the operation of the pump 22 and the operation of the electrolysis unit 23 to cause the anode 111 and the cathode 112 to operate The power-on is stopped (S210). Thereby, the discharge of ozone water from the discharge port 14 is stopped.

On the other hand, when the operation button 61 is still pressed after the third time has elapsed ( S209 : YES), the control unit 81 stops the operation of the electrolysis unit 23 while the pump 22 continues to operate ( S217 ). After that, the process returns to S204, and when the second time has elapsed since the electrolysis unit 23 was stopped (S204: YES), the control unit 81 operates the electrolysis unit 23 again (S205). In this way, the control unit 81 repeats the processes of S204 to S209 and S217 until the operation button 61 is released. Thereby, the pump 22 continues to operate, and the electrolysis unit 23 repeats the stop for the second time and the operation for the third time. Thereby, while the operation button 61 is pressed, the rain-like ozone water is continuously discharged from the discharge port 14 of the casing 10 . When the operation button 61 is released (S209: NO), the control unit 81 stops the operation of the pump 22 and the electrolysis unit 23 (S210).

It should be noted that although the flowchart of FIG. 10 is not shown, even when the operation button 61 is still being pressed, when a limited time (for example, 10 seconds) has elapsed since the operation button 61 was started to be pressed , the control unit 81 also shifts to S210 to stop the operation of the pump 22 and the electrolysis unit 23 .

When the fourth time (eg, 0.3 seconds) has elapsed since the pump 22 and the electrolysis unit 23 were stopped ( S211 : YES), the control unit 81 locks the rain valve 34 ( S212 ). In this way, the ozone rain emission process is completed.

In S203, it is assumed that the water is not sent to the electrolysis unit 23 even after the second time has elapsed since the pump 22 started to operate. Also, consider the case where water was sent to the electrolysis unit 23 after the pump 22 started to operate, but water was not sent to the electrolysis unit 23 while the pump 22 and the electrolysis unit 23 were operating while the operation button 61 was pressed. The reasons include, for example, that the water in the container 21 decreases to a level where the pump 22 cannot draw it, the pump 22 does not operate normally due to a malfunction or the like, and the suction pipe 24 or the discharge pipe 25 falls off.

In this case, since water does not exist in the flow path 131 of the electrolysis unit 23 , when the anode 111 and the cathode 112 are energized in S205 , current does not easily flow between the anode 111 and the cathode 112 . Therefore, the current value detected by the current detection unit 89 in S206 is smaller than the threshold value.

In S207, when it is determined that the current value is equal to or less than the threshold value (S207: NO), the control unit 81 stops the operation of the electrolysis unit 23 (S213). After that, the control unit 81 repeats the processes of S204 to S207 and S213 until the number of times that the current value is determined to be equal to or less than the threshold value in S207 reaches a predetermined number of times (for example, three times) (S214: NO), and the pump 22 is operated to The anode 111 and the cathode 112 are energized intermittently.

When the water is not sent into the flow path 131 and the state in which the current value is not determined to be larger than the threshold has reached a predetermined number of times in S207 (S214: YES), the control unit 81 stops the operation of the pump 22 (S215). Then, the control unit 81 sets the abnormality flag (S216). After that, when the fourth time has elapsed ( S211 : YES), the control unit 81 locks the rain valve 34 ( S212 ).

FIG. 11 is a flowchart showing the ozone mist emission process.

11 , the control unit 81 opens the mist valve 35 (S301), and then operates the pump 22 when the first time (eg, 0.3 seconds) elapses (S302: YES) (S303).

When the second time (eg, 0.5 seconds) has elapsed since the pump 22 started to operate ( S304 : YES), the control unit 81 operates the electrolysis unit 23 , that is, energizes the anode 111 and the cathode 112 ( S305 ). Then, the control unit 81 detects the current flowing between the anode 111 and the cathode 112 through the current detection unit 89 ( S306 ). When the detected current value is larger than the threshold value ( S307 : YES), the control unit 81 waits for the elapse of a third time (for example, 1 second) after the electrolysis unit 23 is operated ( S308 ). By the operation of the pump 22 and the electrolysis part 23 , the ozone water generated by the electrolysis part 23 is sent to the mist discharge part 50 and stored in the water storage tank 53 .

When the third time period has elapsed (S308: YES), the control unit 81 operates the ultrasonic transducer 52 (S309). Thereby, the mist containing ozone is released from the vibration surface 521 of the mist release part 50 , and the mist is released from the release port 15 of the casing 10 .

If the operation button 61 is not continuously pressed ( S310 : NO), the control unit 81 stops the operation of the pump 22 and the energization of the anode 111 and the cathode 112 ( S311 ). Thereby, the supply of ozone water to the mist discharge|release part 50 is stopped.

On the other hand, when the operation button 61 is still pressed after the third time has elapsed ( S310 : YES), the control unit 81 stops the operation of the electrolysis unit 23 while the pump 22 continues to operate ( S320 ). After that, returning to the process of S304, the control unit 81 repeats the processes of S304 to S310 and S320 until the operation button 61 is released. Thereby, the ozone water is continuously supplied to the mist discharge part 50 while the operation button 61 is being pressed. It should be noted that, in S309, the ultrasonic vibrator 52 continues to operate. When the operation button 61 is released (S310: NO), the control unit 81 stops the operation of the pump 22 and the electrolysis unit 23 (S311).

It should be noted that although the flowchart of FIG. 11 is not shown, even when the operation button 61 is still being pressed, when a limited time (for example, 10 seconds) has elapsed since the operation button 61 was started to be pressed , the control unit 81 also shifts to S311 to stop the pump 22 and the electrolysis unit 23 from operating.

When the fourth time (for example, 0.3 seconds) has elapsed since the pump 22 and the electrolysis unit 23 were stopped (S312: YES), the control unit 81 locks the mist valve 35 (S313).

When the fifth time has elapsed since the operation of the ultrasonic transducer 52 ( S314 : YES), the control unit 81 stops the operation of the ultrasonic transducer 52 ( S315 ). The fifth time is set as the time when all the ozone water stored in the water storage tank 53 is released, and the longer the time when the operation button 61 is pressed, the larger the supply amount of ozone water to the water storage tank 53, the longer the fifth time is. .

In this way, the ozone mist release process is completed.

Similar to the ozone rain emission process, the case where water is sent to the electrolysis unit 23 without the operation of the pump 22 is considered. In this case, the current value detected by the current detection unit 89 in S306 is smaller than the threshold value.

In S307, when it is determined that the current value is equal to or less than the threshold value (S307: NO), the control unit 81 stops the operation of the electrolysis unit 23 (S316). After that, the control unit 81 repeats the processes of S304 to S307 and S316 until the number of times that the current value is determined to be equal to or less than the threshold value in S307 reaches a predetermined number of times (for example, three times), and the control unit 81 operates the pump 22 to the anode 111 and the cathode 112 Power on intermittently.

When it is not determined in S307 that the state where the current value is larger than the threshold has reached a predetermined number of times (S317: YES), the control unit 81 stops the pump 22 (S318). Then, the control unit 81 sets the abnormality flag (S319). After that, when the fourth time has elapsed (S312: YES), the control unit 81 locks the mist valve 35 (S313). Then, when the ultrasonic vibrator 52 is in operation, after the fifth time period has elapsed ( S314 : YES), the control unit 81 stops the operation of the ultrasonic vibrator 52 ( S315 ).

In the ozone rain emission treatment and the ozone mist emission treatment, the anode 111 and the cathode 112 of the electrolysis unit 23 are energized after the second time has elapsed since the pump 22 started to operate (S203 to S205 in FIG. 10 and S303 to S305 in FIG. 11 ). ), the anode 111 and the cathode 112 are less likely to be energized in a state where no water exists in the flow path 131 of the electrolysis unit 23, and these

electrodes

111 and 112 are less likely to be damaged.

In addition, when the current value that flows by energizing the anode 111 and the cathode 112 is equal to or less than the threshold value and it is considered that there is no water in the flow path 131, the operation of the pump 22 and the electrolysis unit 23 is stopped (S206, S207, and S207 in FIG. 10 ). S213 to S215 and S306 , S307 , and S316 to S318 in FIG. 11 ), the anode 111 and the cathode 112 are less likely to be damaged.

Then, the rain valve 34 and the mist valve 35 are opened before the pump 22 is operated (S201 to S203 in FIG. 10 and S301 to S303 in FIG. 11 ), and the rain valve 34 and the mist valve 35 are closed after the pump 22 is stopped ( 10 to S212 and S311 to S313 of FIG. 11 ), therefore, the water supply pressure of the pump 22 can prevent the common pipe 31 from coming off the outflow port 134 of the electrolysis unit 23 or the discharge pipe 25 from coming off the discharge port 223 of the pump 22 .

Returning to FIG. 9 , when any of the release processes is executed ( S104 , S105 ), the control unit 81 determines whether or not an abnormality flag is set ( S106 ). When the abnormal flag is not set ( S106 : NO), the control unit 81 temporarily ends the control process and starts the control process from the beginning.

When an abnormality in water supply occurs during the execution of the discharge process, an abnormality flag is set. When the abnormality flag is set ( S106 : YES), the control unit 81 causes the mode display unit 13 to notify the abnormality ( S107 ). For example, the mode display unit 13 blinks in any color or different colors corresponding to the two operation modes. Alternatively, the mode display unit 13 is lit in a color different from the color corresponding to the two operation modes.

When the abnormality notification is performed by setting the abnormality flag, in the subsequent control processing, it is determined in S101 that the abnormality flag is set (S101: YES). Therefore, the control unit 81 does not perform the processing after S102, that is, does not accept the operation of the operation unit 60, and does not execute the ozone rain emission process and the ozone mist emission process even if the user presses the operation button 61. Thereby, the pump 22 and the electrolysis unit 23 are not operated, and the ozone water is not sprayed by the ozone sprayer 1 .

When the water supply abnormality is caused by, for example, a decrease in the amount of water in the container 21 , the user performs a release operation after replenishing the water in the container 21 . By the control unit 81, the abnormality notification by the mode display unit 13 is stopped and the abnormality flag is reset. Thereby, in the control process of FIG. 9, the operation performed by the operation part 60 is accepted.

It should be noted that, in the present embodiment, the pump 22 is a diaphragm-driven pump, and the discharge port 223 has a check valve 228. When the pump 22 stops operating to stop sending water from the pump 22, the check valve 228 is closed. closure. This prevents water such as ozone water existing in the flow path 131 of the electrolysis unit 23 from flowing to the pump 22 side without being sent to the rain discharge section 40 and the mist discharge section 50, and the flow path 131 remains in a state where water remains. Thereby, when the operation button 61 is pressed next time, water tends to exist in the flow path 131 . Therefore, with the configuration in which the check valve 228 functions as a blocking portion for blocking the flow of water to the pump 22 side in this way, it is also possible to prevent energization between the anode 111 and the cathode 112 in a state where no water exists in the flow path 131 , Therefore, the anode 111 and the cathode 112 are less likely to be damaged.

According to the present embodiment, in the ozone rain emission treatment and the ozone mist emission treatment, the anode 111 and the cathode 112 of the electrolysis unit 23 are energized after the second time has elapsed since the pump 22 started to operate. Thereby, the water drawn from the container 21 can be sent into the flow path 131 of the electrolysis unit 23 before the anode 111 and the cathode 112 are energized. Therefore, it is difficult to energize the anode 111 and the cathode 112 in a state where no water exists in the flow path 131, and these

electrodes

111 and 112 are less likely to be damaged.

Further, according to the present embodiment, when it is determined that there is no water in the flow path 131 after the pump 22 is activated, the mode display unit 13 performs an abnormality notification as an abnormality process based on the determination result. Thereby, the user can grasp the fact that water is not being supplied to the electrolysis unit 23 normally, and can appropriately take measures such as replenishment of water when there is no water in the container 21 .

Furthermore, according to the present embodiment, even if the operation unit 60 is operated, the operation of the pump 22 and the energization of the anode 111 and the cathode 112 are not performed as abnormal processing. As a result, the pump 22 can be prevented from operating in vain, and the anode 111 and the cathode 112 are less likely to be damaged.

Furthermore, according to the present embodiment, it is possible to determine whether or not water exists in the flow path 131 by detecting the current flowing when the anode 111 and the cathode 112 are energized by the current detection unit 89 .

The embodiments of the present invention have been described above, but the present invention is not limited to the above-described embodiments and the like, and various modifications other than those described above can be made in the embodiments of the present invention.

For example, in the above-described embodiment, the diaphragm pump 22 is used as the water supply device for sending the water drawn from the container 21 to the rain discharge part 40 and the mist discharge part 50 through the flow path 131 of the electrolysis part 23 . In addition, when the pump 22 is used, the check valve 228 provided in the discharge port 223 functions as a blocking part that blocks the flow of water from the inside of the flow path 131 of the electrolysis part 23 to the pump 22 side. However, like the pump 22 , a piston-type pump in which the check valve functions as the blocking portion may be used, and another type of pump that does not have a structure as the blocking portion may also be used.

In addition, in the above-described embodiment, in order to generate ozone water, the rod-shaped anode 111, the wire-shaped cathode 112 spirally wound around the outer periphery of the anode 111, and the ion exchange between the anode 111 and the cathode 112 are used. The ozone electrode unit 110 constituted by the membrane 113 is arranged in the electrolysis unit 23 in the flow path 131 of the case 130 . However, as an electrolysis unit having another structure, for example, as the electrolysis unit of the ozone electrode unit, a membrane-electrode assembly including a rod-shaped anode, a holding anode, and a It consists of a cathode having a curved cathode claw portion, a separator arranged on the cathode claw portion and separating the anode from the cathode, and an anode terminal connected to the anode.

Moreover, in the said embodiment, the ozone sprayer 1 is provided with the rain discharge|release part 40 which discharge|releases ozone water in the form of rain. However, the ozone sprayer 1 may include, instead of the rain discharge part 40 , a discharge part having a nozzle having a nozzle that discharges the ozone water in a mist shape having a particle size larger than that of the mist discharge part 50 .

Furthermore, in the above-described embodiment, the mist discharge unit 50 has a configuration including the water storage tank 53 that stores the ozone water from the generation unit 20 and the ultrasonic vibrator 52 that atomizes the ozone water stored in the water storage tank 53 by ultrasonic vibration. However, the mist discharge part 50 is not limited to the above-mentioned structure, For example, the structure which has the nozzle which discharge|releases the ozone water in the form of a mist may be sufficient.

Furthermore, in the above-described embodiment, the ozone sprayer 1 includes both the rain releasing unit 40 and the mist releasing unit 50 as the releasing unit that releases the ozone water in the form of rain or mist, but may include only one of them. When the rain releasing unit 40 is not provided, the ozone rain releasing process of FIG. 10 is not performed, and when the mist releasing unit 50 is not provided, the ozone mist releasing process of FIG. 11 is not performed.

Furthermore, in the above-described embodiment, the abnormality notification is performed by the mode display unit 13, but the ozone sprayer 1 may be provided with a dedicated display unit for performing abnormality notification. In addition, notification of abnormality can be realized not only by display, but also by sound from a speaker or a sound from a buzzer.

Furthermore, in the above-described embodiment, it is determined whether or not water exists in the flow path 131 based on the current detected by the current detection unit 89 . However, the electrolysis unit 23 may be provided with a flow sensor that detects the flow rate of water flowing in the flow path 131 as a detection section, and may determine whether or not water exists in the flow path 131 based on the detected flow rate of the flow sensor.

Furthermore, in the above-described embodiment, in the ozone rain emission process of FIG. 10 and the ozone mist emission process of FIG. 11 , it is determined whether or not the number of times that the current value detected by the current detection unit 89 is determined to be equal to or less than the threshold value has reached a predetermined number (S214, S214, S214). S317). However, it is possible to shift to the process of stopping the pump 22 ( S215 , S318 ) only if it is determined that the detected current value is equal to or less than the threshold value, without making the determination of whether or not the predetermined number of times has been reached.

Furthermore, in the above-described embodiment, the switching unit 36 for switching which of the rain pipe 32 and the mist pipe 33 to flow the ozone water flowing out from the generating unit 20 is composed of the rain valve 34 and the mist valve. 35 These two solenoid valves constitute. However, the switching portion 36 may be constituted by a three-way valve. In this case, the common pipe 31 is connected to the inlet of the three-way valve. In addition, the rain pipe 32 and the mist pipe 33 are composed of a single pipe, and are connected to one outlet and the other outlet of the three-way valve, respectively. In the ozone rain emission process of FIG. 10 , after switching so that the ozone water flows through the rain pipe 32 in the three-way valve, the pump 22 is operated. In the ozone mist release process of FIG. 11, after switching so that the ozone water may flow through the pipe 33 for mist in a three-way valve, the pump 22 is operated.

Furthermore, in the above-described embodiment, the container 21 , the electrolysis unit 23 , and the power supply unit 70 are arranged inside the trunk portion 10 a of the casing 10 . However, the entire trunk portion 10a may be used as a water storage portion as a container, and the electrolysis portion 23 and the power source portion 70 may be arranged on the neck portion 10b or the head portion 10c of the casing 10 . In this case, the electrolysis part 23 and the power supply part 70 have the size which can be arrange|positioned at the neck part 10b or the head part 10c.

Furthermore, in the above-described embodiment, a water level detection unit capable of detecting the water level in the container 21 may be provided, and when the water level detection unit detects that the water level has dropped to such an extent that water cannot be drawn by the pump 22, even if When the operation button 61 is operated, the pump 22 and the electrolysis unit 23 do not operate. In this way, it is possible to prevent energization between the anode 111 and the cathode 112 without the water passing through the flow path 131 of the electrolysis unit 23 , thereby further protecting the anode 111 and the cathode 112 .

Furthermore, in the above-described embodiment, the electrolysis unit 23 is disposed downstream of the pump 22 , and the water drawn from the container 21 and sent from the pump 22 is taken into the electrolysis unit 23 . However, the electrolysis part 23 may be arranged upstream of the pump 220 , and the water in the container 21 may pass through the electrolysis part 23 before being sucked into the pump 22 . In either configuration, the pump 22 sends the water drawn from the container 21 to the rain discharge part 40 and the mist discharge part 50 through the flow path 131 of the electrolysis part 23 .

In addition, the embodiment of the present invention can be appropriately modified in various ways within the scope of the technical idea shown in the claims.
