Description

The present invention relates to a split-type ozone generator. In particular, the present invention relates to a split-type ozone generator that generates a large amount of ozone and is easy to maintain.

It has been known that ozone can be generated by corona discharge. In corona discharge for ozone generation, a device is known that generates ion wind by applying high voltage between a metal layer having a cavity pattern and a rod-shaped electrode placed at the center axis of the cavity pattern. (See Patent Document 1).

In such an ozone generator, dirt may adhere to the electrodes due to long-term corona discharge. When dirt adheres to the electrodes, it becomes difficult for discharge to occur, and the efficiency of ozone generation also decreases. Therefore, it is necessary to clean the electrodes depending on the usage conditions. In addition, metal parts other than the electrodes, that is, metal parts of the electrical system that supplies power to the electrodes and controls the supplied power, are also included in the device. Metal parts other than these electrodes, especially metal parts such as electrical contacts, become oxidized when they come in contact with ozone, resulting in a decline in function and performance (such as an increase in the contact resistance of the contacts). There was a problem.

However, cleaning the electrodes is unfamiliar to general users, and may deform electrodes with delicate structures, especially thin rod-shaped electrodes. Therefore, the first object of the present invention is to provide an ozone generator that allows a user to easily deal with dirt on the electrodes. A second objective is to prevent metal parts other than the electrode portions (particularly metal parts of the electrical system) from being exposed to ozone and oxidized.

In order to solve the above problems, the divided ozone generator 1 according to the first aspect of the present invention has a substantially annular first conductive region 14, as shown in FIGS. 1 and 2, for example. a plate-shaped first electrode 10 (12) in which a first electrode part 13 is formed; a second electrode 20 disposed at a position apart from the first electrode 10; the first electrode part of the first electrode 10; 13 and a second electrode 20 having a rod-shaped second electrode part 24 extending toward the first electrode 10 on the central axis of the electrode part 30; An ozone generating unit 90 including an electrode side casing 50 in which an ozone wind outlet 52 is formed through which the ozone wind flows out, and the first terminal 42 connected to the power line 44 that supplies power to the electrode unit 30 is connected to the electrode side. an ozone generating section 90 provided on the outer surface of the casing 50; a power source 110 for supplying power to the electrode section 30; a control device 120 for controlling power supplied from the power source 110 to the electrode section 30; The power supply unit 100 includes a power supply casing 150 that includes a device 120 and a second terminal 142 connected to a power line 144 that extracts power from the power source 110 on the outer surface of the power supply casing 150. Preparation: The electrode side casing 50 is integrally assembled to the power supply side casing 150 and is removable, and when assembled integrally, the first terminal 42 and the second terminal 142 are connected.

With this configuration, corona discharge occurs when power is supplied between the first electrode part and the second electrode part, and ozone is generated. The generated ozone flows out from the ozone air outlet and supplies ozone to the environment around the split-type ozone generator. In addition, the electrode side casing and the power supply side casing are assembled together and removable, so they are used as one body when generating ozone, but they can be removed during maintenance, for example, and the ozone generation part and the power supply part Since these can be handled separately, for example, when the electrode section becomes dirty, it is possible to clean or replace only the ozone generating section, allowing the user to easily deal with the dirt on the electrode. Furthermore, since the power source and control device are housed in a power supply side casing that is separate from the ozone generating section, the power source and control device are less susceptible to the effects of ozone, and oxidation of these metal parts is prevented.

In the split-type ozone generator 1 according to the second aspect of the present invention, as shown in FIG. It has two electrode parts 24. With this configuration, corona discharge occurs between the plurality of first electrode parts and the second electrode part, and ozone is generated, so even a split-type ozone generator of the same size can generate a large amount of ozone. can.

In the split-type ozone generator 1 according to the third aspect of the present invention, as shown in FIG. It has been airtight since the 1990s. With this configuration, the power supply section is airtight from the ozone generation section, so ozone generated in the ozone generation section does not enter the power supply section, and metal parts of the power supply section are prevented from being oxidized by ozone. be done.

In the divided ozone generator 1 according to the fourth aspect of the present invention, for example, as shown in FIG. 3, the first terminal 42 has a seal structure 72 that prevents ozone from entering. With this configuration, since the first terminal has a seal structure that prevents ozone from entering, ozone is prevented from leaking through the power line or the first terminal, and the first terminal and the second terminal connected to the first terminal are prevented from leaking through the power line or the first terminal. The terminals are also prevented from being oxidized by ozone.

In the split type ozone generator 1 according to the fifth aspect of the present invention, as shown in FIG. It is formed on the opposite side from where it is located. With this configuration, air is sent to the electrode part from the air inlet formed on the opposite side of the first electrode to the second electrode, and the ozone wind generated in the electrode part flows out from the ozone wind outflow part. The flow of air or ozone within the ozone generator becomes smooth, and the ozone supply efficiency of the split-type ozone generator increases.

In the split-type ozone generator 1 according to the sixth aspect of the present invention, the air inlet 54 is formed at a position facing the second electrode section 24, as shown in FIG. 4, for example. With this configuration, air flowing in from the air inlet formed at a position facing the second electrode part flows directly to the second electrode part, so the air or ozone in the ozone generating part flows smoothly, and the split type The ozone supply efficiency of the ozone generator increases.

In the split-type ozone generator 1 according to the seventh aspect of the present invention, as shown in FIG. It is formed at a position facing the first electrode part 13. With this configuration, the ozone wind generated by converting air into ozone between the first electrode part and the second electrode part directly flows out from the ozone wind outlet formed at a position facing the first electrode part. , the flow of air or ozone within the ozone generator becomes smoother, and the ozone supply efficiency of the split-type ozone generator becomes higher.

In the divided ozone generator 1 according to the eighth aspect of the present invention, a convex portion 58 is formed around the air inlet 54 on the outer surface of the electrode side casing 50, as shown in FIG. 5, for example. With this configuration, even when the split-type ozone generator is placed on a table, etc. with the air inlet facing down and the ozone air outlet facing up, there is no space between the split-type ozone generator and the table, etc. A space for air to flow is secured, and the air flows smoothly from the air inlet, which prevents the ozone supply efficiency of the divided ozone generator from decreasing.

In the divided ozone generator 1 according to the ninth aspect of the present invention, as shown in FIG. 4, for example, the position of the electrode side casing 50 facing the first electrode 10 and the position facing the second electrode 20 are different A side air inlet 56 is formed in the side surface 50S. With this configuration, since air also flows in from the side air inlet, the air flow inside the ozone generator becomes smooth, and the ozone supply efficiency of the divided ozone generator increases.

In the split-type ozone generator 1 according to the tenth aspect of the present invention, as shown in FIG. Formed on the side of the body. With this configuration, the air flowing in from the side air inlet passes through the second electrode side of the first electrode and flows to the first electrode, causing corona discharge between the first electrode and the second electrode. This makes it easier to turn into ozone, generate ozone wind, and increase the ozone supply efficiency of the split-type ozone generator.

In the split-type ozone generator 1 according to the eleventh aspect of the present invention, as shown in FIG. 4, for example, the first electrode 10 is A rectifier plate 60 extending toward the surface on the second electrode 20 side is formed. With this configuration, the ozone wind generated at the electrode part is prevented from flowing back to the second electrode side, and the air flowing in from the side air inlet is more reliably flowed between the first electrode and the second electrode. The ozone gas escapes and flows to the first electrode, and ozone wind is easily generated due to corona discharge between the first and second electrodes, increasing the ozone supply efficiency of the split type ozone generator.

In the divided ozone generator 1 according to the twelfth aspect of the present invention, the power supply section 100 has an airtight structure, as shown in FIG. 3, for example. With this configuration, since the power supply part has an airtight structure, ozone present in the environment surrounding the split type ozone generator does not enter the power supply part, and the metal parts of the power supply part are prevented from being oxidized by ozone. Prevented.

In the split-type ozone generator 1 according to the thirteenth aspect of the present invention, for example, as shown in FIG. has a third terminal 46 connected to a communication line 48 connected to the memory 80 on the outer surface of the power supply side casing 150; has a fourth terminal 146 connected to a communication line 148 connected to the control device 120 on the outer surface of the power feeding side casing 150; When the side casing 50 is assembled integrally with the power supply side casing 150, the third terminal 46 and the fourth terminal 146 are connected. With this configuration, the ozone generator has a memory for recording the operation of the electrode section, and when the electrode side casing and power supply side casing are assembled together, it is connected to the power supply section, so the operation of the electrode section can be recorded. In addition to being able to record, the ozone generator and power supply unit can be removed and handled separately, so when only the ozone generator is replaced, the memory itself will be new, so you can start recording the operating hours from 0, and when replacing the ozone generator, the memory itself will be new. The operation time of the new ozone generator can be recorded reliably.

In the divided ozone generator 1 according to the fourteenth aspect of the present invention, the control device 120 issues an alarm or initiates an operation when the operating time of the electrode section 30 recorded in the memory 80 exceeds a predetermined threshold. Configured to stop. With this configuration, when the operating time of the electrode section exceeds a predetermined threshold, an alarm is issued or the operation is stopped, thereby preventing the electrode section from being operated for an inappropriately long time exceeding the predetermined threshold. can do.

According to the present invention, the split-type ozone generator includes a plate-shaped first electrode in which a first electrode portion having a substantially annular first conductive region is formed, and a position spaced apart from the first electrode. an electrode portion, the second electrode having a rod-shaped second electrode portion extending toward the first electrode on the central axis of the first electrode portion of the first electrode; an electrode side casing in which an ozone wind outlet is formed through which the ozone wind generated in the electrode part flows out; an ozone generating section provided on the outer surface of the electrode side casing; a power source for supplying power to the electrode section; a control device for controlling the power supplied from the power source to the electrode section; and a power supply side that includes the power source and the control device. a power feeding unit comprising a casing, the power feeding unit having a second terminal connected to a power line for extracting power from the power source on the outer surface of the power feeding side casing; the electrode side casing is integrally assembled with the power feeding side casing, In addition, it is removable and when assembled together, the first terminal and the second terminal are connected, so when generating ozone, the ozone generating part and the power feeding part can be used as one, and for example, during maintenance. The ozone generator and power supply section can be removed and handled separately, allowing the user to easily deal with dirt on the electrodes, and the power supply and control device are housed in a separate electrode-side casing from the ozone generation section. The ozone generating device is such that the metal parts and the control device are not easily affected by ozone, and the oxidation of these metal parts is prevented.

Embodiments of the present invention will be described below with reference to the drawings. In each figure, parts that are the same or correspond to each other are given the same reference numerals, and redundant explanations will be omitted. FIG. 1 is a conceptual diagram of a split-type ozone generator 1 as an embodiment of the present invention. The split-type ozone generator 1 includes an ozone generating section 90 that houses an electrode section 30 that generates ozone, a power source 110 that supplies power to the electrode section 30, and a power source that controls the power supplied from the power source 110 to the electrode section 30. Alternatively, it is roughly divided into a power supply section 100 that houses a control device 120 that controls the operation of the split-type ozone generator 1 .

The electrode section 30 includes a plate-shaped first electrode 10 and a second electrode 20 having a rod-shaped second electrode section 24 spaced apart from the first electrode 10 . The plate-shaped first electrode 10 may be a single plate electrode or a combination of a plurality of plate electrodes. In FIG. 1, the plate-shaped first electrode 10 is composed of three plate electrodes 12, 16, and 18, but the present invention is not limited to this. To explain the plate electrode 12 in detail, in the example shown in FIG. 1, seven first electrode parts 13 are formed on the plate electrode 12. The number of first electrode parts 13 may be one or more, or any number, and the arrangement thereof may be arbitrary. However, as shown in FIG. 1, it is preferable to arrange the seven first electrode parts 13 at equal intervals because it is easy to generate a large amount of uniform ozone air.

The first electrode part 13 has a substantially circular first cavity, a substantially annular second cavity that is coaxial with the first cavity, and is formed outside the first cavity. A substantially annular first conductor region 14 is formed between the cavity and the cavity. Here, "substantially circular" is a shape including a circle, a polygon, an ellipse, a rice ball shape, etc., and is a shape that forms the inner edge (inner diameter) of a substantially annular shape, which will be described later. Furthermore, the term "substantially circular" refers to a shape in which the outer and inner edges are sandwiched between the above-mentioned "substantially circular" shapes, and may include portions where the annular shape is discontinuous. Note that it is preferable that both the substantially circular shape and the substantially annular shape be circular because the distance to the second electrode portion 24 can be made equal. Note that the substantially annular first conductive region 14 is electrically and mechanically connected to the plate electrode by a conductive connecting portion 14a.

The second electrode section 24 is a rod-shaped member. The tip of the rod-shaped member (the end closer to the first electrode part 13) may be sharp, or may be smooth or flat without being sharp. The second electrode portion 24 of the rod-like member may be fixed to one plate-like member 22 and maintain its posture. Note that the second electrode portion 24 may not be rod-shaped but may be a square member having a polygonal cross section, or may be formed by punching and bending the same plate material as the plate member 22. An opening may be formed in the plate member 22 to allow air to pass therethrough, and the shape thereof is arbitrary. Further, the plurality of second electrode portions 24 may be fixed to one plate member 22, or may be connected to each other with a bar or the like to maintain their posture and be electrically connected. The second electrode section 24 is arranged on the substantially annular central axis of the first electrode section 13 . Here, on the central axis of the approximately annular shape may be any axis that is within the inner edge of the approximately annular shape and intersects with the plane of the first electrode 10 (plate electrode 12), and preferably on the axis that intersects the plane of the first electrode 10 (plate electrode 12). on an axis that intersects the plane of at an angle of 70 degrees or more, more preferably on an axis that intersects at an angle of 80 degrees or more, or on an axis that intersects at an angle substantially perpendicular to the plane of the plane. Further, it is preferable that the tip of the second electrode section 24 be at an equal distance from the first electrode section 13.

By applying a positive voltage to the first electrode 10 configured in this way and a negative voltage to the second electrode 20, a corona discharge is generated between the first electrode part 13 and the second electrode part 24, and the air is ionized. Oxygen in the air becomes ozone. The ions flow to the first electrode 10 side of the positive voltage, producing an ozone wind. Note that when the first electrode 10 has a plurality of plate electrodes, for example, plate electrodes 12, 16, and 18, the plate electrode 16 on the second electrode 20 side from the plate electrode 12 has a first conductor region 14. A substantially annular conductor region with a larger diameter is formed in the plate electrode 18 on the second electrode 20 side, and a substantially circular cavity with an even larger diameter is formed, and the vicinity of the inner edge of the cavity becomes the conductor region. preferable. Preferably, the plate electrodes 12, 16, and 18 are parallel to each other. With this configuration, more ozone wind is generated.

The first electrode 10 and the second electrode 20 are enclosed in an electrode-side casing 50. The electrode side casing 50 is formed with an ozone air outlet 52 through which at least the ozone air generated in the electrode section 30 flows out. A pair of power lines 44 that supply power to the first electrode 10 and the second electrode 20 are connected within the electrode side casing 50, and a first terminal 42 is connected to the end thereof. The first terminal 42 is exposed to the outside of the electrode-side casing 50 on the power supply section 100 side when the ozone generation section 90 is assembled integrally with the power supply section 100. That is, the first terminal 42 becomes the outer surface of the electrode side casing 50. Strictly speaking, the first terminal 42 is two terminals, one on the positive voltage side and the other on the negative voltage side, but here they are collectively referred to as the first terminal 42, and the positive voltage side terminal and the negative voltage side terminal are not connected even if they are adjacent to each other. Alternatively, they may be spaced apart as shown in FIG.

Further, it is preferable that a memory 80 for recording the operating time of the electrode section 30 is included in the electrode side casing 50. The memory 80 will be described later. A plurality of communication lines 48 such as a pair of communication lines for communicating driving information data are connected to the memory 80, and a third terminal 46 is connected to the end thereof. The third terminal 46 is exposed to the outside of the electrode side casing 50 on the power supply section 100 side when the ozone generation section 90 is assembled integrally with the power supply section 100. Typically, it is arranged in line with the first terminal 42. Strictly speaking, the third terminal 46 is a plurality of terminals, such as a pair of two terminals, but here they are collectively referred to as the third terminal 46, and the plurality of terminals may be adjacent to each other, or as shown in FIG. may be spaced apart from each other.

In the power supply unit 100, a power supply 110 and a control device 120 are included in a power supply side casing 150. Power source 110 is typically a battery, but may also be a known power source such as a fuel cell. When the power source 110 is a battery, a battery charging terminal 112 is provided in the power feeding side casing as necessary, and a charging wiring 114 connecting the charging terminal 112 and the power source 110 is housed in the power feeding side casing. A pair of power lines 144 are connected to the power source 110, and a second terminal 142 is connected to the ends thereof. The second terminal 142 is exposed to the outside of the power supply side casing 150 on the ozone generation unit 90 side when the ozone generation unit 90 is assembled integrally with the power supply unit 100 . That is, the second terminal 142 becomes the outer surface of the power feeding side casing 150. The second terminal 142 also has two terminals, one on the positive voltage side and one on the negative voltage side, but they are collectively referred to as the second terminal 142 here. Further, a plurality of communication lines 148 such as a pair of communication lines are connected to the control device 120, and a fourth terminal 146 is connected to the end thereof. The fourth terminal 146 is exposed to the outside of the electrode-side casing 50 on the power feeding unit 100 side when the ozone generating unit 90 is assembled integrally with the power feeding unit 100. Typically, it is arranged in line with the second terminal 142. The fourth terminal 146 is also a plurality of terminals, such as a pair of two terminals, but they are collectively referred to as the fourth terminal 146 here. The second terminal 142 and the fourth terminal 146 are arranged at positions where they are connected to the first terminal 42 and the third terminal 46, respectively, when the ozone generating section 90 is assembled integrally with the power feeding section 100. A switch 130 for a user to operate the divided ozone generator 1 is installed in the power supply unit 100. The switch 130 may instruct the starting/stopping of the divided ozone generator 1 and the amount of ozone generated, that is, the voltage to be applied to the electrode section 30. The control device 120 controls the voltage applied to the electrode section 30 from the power source 110 based on instructions from the switch 130.

As shown in FIG. 2, the ozone generating section 90 and the power feeding section 100 are assembled together and are removable from each other. As shown in FIG. 2, when the casing convex portion 152, which is an annular projection formed on the power supply side casing 150, is inserted into the casing recess 51, which is a depression formed on the electrode side casing 50, the ozone generating part 90 and the power supply part 100 can be stably assembled into one body. Further, for example, it is preferable to form a pawl 154 on the casing convex portion 152 so that the pawl 154 engages with a recess (not shown) formed on the casing concave portion 51 so that the assembly will not come loose. As shown in FIG. 2, when the first terminal 42 is arranged inside the casing recess 51 of the electrode side casing 50 and the second terminal 142 is arranged inside the casing convex part 152 of the power supply side casing 150, the ozone generating section 90 and the power supply section 100 are arranged. It is preferable that when the first terminal 42 and the second terminal 142 are removed, the first terminal 42 and the second terminal 142 are surrounded to prevent the user from touching them or from coming into contact with other objects. Note that the method and configuration for assembling and removing the ozone generator 90 and the power supply unit 100 are not limited to this, and may be any known method or configuration.

When the ozone generation section 90 and the power supply section 100 are assembled together, the first terminal 42 and the second terminal 142 are connected, and power can be supplied from the power source 110 to the electrode section 30. Ozone wind is generated by supplying electric power to the electrode section 30. On the other hand, by removing the ozone generating section 90 and the power feeding section 100, the electrode section 30, which is easily contaminated by corona discharge, can be cleaned and replaced. That is, in the split type ozone generator 1, by removing the electrode section 30 that is easily soiled from the power supply section 100, which includes the power supply 110, control device 120, etc., which are sensitive to liquids such as water, liquid cleaning using water or alcohol can be performed. It becomes easier to do. Furthermore, the electrode section 30 can be easily replaced as a cassette component. Therefore, the split-type ozone generator 1 allows the user to easily deal with dirt on the electrodes.

Next, with reference to FIG. 3, a structure for making the divided ozone generator 1 airtight will be described. In FIG. 3, the control device 120, the communication lines 48, 148, the third terminal 46, the fourth terminal 146, and the communication line between the control device 120 and the switch 130 are not shown and are formed on the electrode side casing 50. The ozone air outlet 52 that has been removed is indicated by a chain line. Since the oxidizing power of ozone is strong, ozone generated in the electrode section 30 oxidizes the connection terminals such as the first terminal 42, the second terminal 142, the third terminal 46, and the fourth terminal 146, and then enters the power supply section 100. This may oxidize metal parts of the electrical system, such as the power supply 110 and the control device 120. Therefore, first, measures to prevent ozone from entering the power supply unit 100 will be explained. In order to fixedly support the second terminal 142 and the fourth terminal 146 of the power feeding unit 100 at the portion where the second terminal 142 and the fourth terminal 146 extend to the outer surface of the power feeding side casing 150, that is, the portion where the second terminal 142 and the fourth terminal 146 penetrate the power feeding side casing 150. A second terminal support 170 is formed to be thicker than the power feeding side casing 150. Note that the second terminal support 170 may be molded integrally with the power feeding side casing 150, or may be molded separately and then integrated. Then, the space between the second terminal 142 and the fourth terminal 146 and the second terminal support 170 is made airtight. For example, the second terminal support 170 may be made of a known elastic material such as soft plastic or rubber to make it airtight, or a seal material may be used between the second terminal 142 and the fourth terminal 146 and the second terminal support 170. may be filled with. By making the space between the second terminal 142 and the fourth terminal 146 and the second terminal support 170 airtight, it is possible to prevent ozone on the ozone generating section 90 side from entering the power feeding section 100 side. Further, the second terminal 142 may have a movable part such as a spring to ensure connection with the first terminal 42. In that case, the part of the second terminal support 170 that accommodates the movable part of the second terminal 142 requires clearance in order to be movable, so it cannot be airtight; Airtightness is possible by making sure that the parts are in close contact with each other without any gaps. Of course, this can also be applied to the fourth terminal 146.

Note that by making the entire power feeding side casing 150 including the second terminal support 170 airtight, even if ozone generated in the split type ozone generator 1 stays around, it can be prevented from entering the power feeding part 100. preferable. In order to make the entire power supply side casing 150 airtight, a sealing structure may be formed in the same manner as the second terminal support 170 even at the opening portion. In addition, even when the power supply section 100 is not integrated with the ozone generation section 90, that is, when the power supply section 100 is alone, an elastic sheet with slits is used to prevent the surface of the second terminal 142 from being oxidized. may be provided. That is, a sheet provided with a slit at a position facing the second terminal 142 is installed so as to cover the second terminal 142 . When the sheet is removed from the ozone generating section 90, the opposite sides of the slit are in close contact with each other due to the elasticity of the sheet, and the slit is closed, preventing ventilation, thereby preventing the second terminal 142 from oxidizing. When integrated with the ozone generator 90, the first terminal 42 pushes open the slit and passes through, allowing contact with the second terminal 142. Further, locations that can become openings such as the battery charging terminal 112 may be sealed by providing a charging terminal cover 116 made of rubber, for example. Further, the switch 130 may also be covered with a rubber sheet to provide an airtight structure, but the airtight structure of these parts is not particularly limited and may be made airtight by a known method.

In addition, the first terminal 42 and the third terminal 46 of the ozone generating section 90 are fixed to a portion where the first terminal 42 and the third terminal 46 are exposed to the outer surface of the electrode side casing 50, that is, a portion where the first terminal 42 and the third terminal 46 penetrate the electrode side casing 50. A first terminal support 70 is formed to be thicker than the electrode side casing 50 in order to provide support. Like the second terminal support 170, the first terminal support 70 may be molded integrally with the electrode side casing 50, or may be molded separately and then integrated. Preferably, the first terminal 42 and the third terminal 46 and the first terminal support 70 are airtight, similar to the second terminal support. Furthermore, it is preferable that a sealing structure 72 is further provided to make the space between the first terminal 42 and the third terminal 46 and the first terminal support 70 airtight. The seal structure 72 is a plate-shaped member formed of a known elastic material such as soft plastic or rubber, and the first terminal 42 and the third terminal 46 may pass through the seal structure 72 in an airtight manner, or the seal structure 72 may be a plate member made of a known elastic material such as soft plastic or rubber. The coating may be applied to a portion where the third terminal 46 penetrates the first terminal support 70. By further providing a sealing structure 72 that makes airtight between the first terminal 42 and the third terminal 46 and the first terminal support 70, ozone on the ozone generating section 90 side is transferred to the connection terminal (the first terminal support 70) with the power supply section 100 side. The first terminal 42, the second terminal 142, the third terminal 46, the fourth terminal 146, etc.) can be prevented from being oxidized, and furthermore, it can be more reliably prevented from entering the power supply unit 100 side.

Further, as schematically shown by arrows in FIG. 3, the ozone generated at the first electrode 10 flows out from the electrode side casing 50 through the ozone air outlet 52, and flows from the outside to the casing of the electrode side casing 50. It may pass between the recess 51 and the casing protrusion 152 of the power supply side casing 150 and flow to connection terminals such as the first terminal 42, second terminal 142, third terminal 46, and fourth terminal 146. Therefore, a seal structure 172 is provided to cover the portion where the first terminal 42 and the second terminal 142 and the third terminal 46 and the fourth terminal 146 are connected, that is, the first terminal support 70 and the second terminal support 170. is preferable. The seal structure 172 may be a known seal structure for obtaining an airtight structure. By providing the seal structure 172, the connection points between the first terminal 42 and the second terminal 142 and the third terminal 46 and the fourth terminal 146, that is, the connection points between the ozone generation section 90 and the power supply section 100 come into contact with ozone. This can prevent these connection terminals from oxidizing. Furthermore, it is possible to prevent ozone from entering the power supply unit 100. Further, a sealing material may be provided at a portion where the casing recess 51 and the casing protrusion 152 fit together.

Next, with reference to FIG. 4, the flow of air and ozone wind in the ozone generator 90 of the split type ozone generator 1 will be described. In the ozone generating section 90, the ozone wind generated in the electrode section 30 flows out of the electrode side casing 50 from the ozone wind outlet 52, thereby obtaining effects of the ozone wind, such as sterilization and deodorization. In order to smoothly cause the ozone wind generated in the electrode section 30 to flow out from the ozone wind outflow port 52, it is preferable that air inflow ports 54 and 56 are formed in the electrode side casing 50 to take in outside air. Here, the ozone air outlet 52 is preferably formed at a position opposite to the second electrode 20 with respect to the first electrode 10 of the electrode section 30. That is, in FIG. 4, since the first electrode 10 is located above the second electrode 20, the ozone air outlet 52 is formed in the electrode-side casing 50 above the first electrode 10. By forming the ozone wind outlet 52 in this way, the ozone wind generated by the corona discharge between the second electrode part 24 and the first electrode part 13 flows toward the first electrode 10, so that it can continue to flow as it is. It will flow out from the ozone air outlet 52. Furthermore, when the ozone air outlet 52 is formed at a position facing the first electrode part 13, that is, at a position directly above the first electrode part 13 in FIG. The ozone wind generated by the corona discharge during this period flows linearly and flows out from the ozone wind outlet 52, which is preferable. Note that the ozone air outlet 52 may be one large opening, or may be a plurality of openings, for example, an opening formed for each first electrode part 13, and the shape and number thereof are not particularly limited. First, it is determined as appropriate based on the dimensions of the ozone generator 90, the material of the electrode side casing 50, the design of the split type ozone generator 1, etc.

The air inlet 54 is preferably formed at a position opposite to the first electrode 10 with respect to the second electrode 20 of the electrode section 30 . That is, in FIG. 4, the air inlet 54 is formed in the electrode side casing 50 below the second electrode 20. By forming the air inlet 54 in this way, air flows in from the second electrode 20 side, and the ozone wind generated by corona discharge between the second electrode part 24 and the first electrode part 13 is transferred to the first electrode part 13. It is suitable for flowing to the electrode 10 side. Furthermore, if the air inlet 54 is formed at a position facing the second electrode part 24, that is, in a position directly below the second electrode part 24 in FIG. This is preferable because it flows and receives the corona discharge between the second electrode part 24 and the first electrode part 13 to become ozone wind.

Furthermore, the side air inlet 56 is located at a position of the electrode side casing 50 facing the first electrode 10, that is, an upper position in FIG. 4, and a position facing the second electrode 20, that is, a lower position in FIG. may be formed at different side surfaces 50S of the electrode side casing, that is, at the left and right positions in FIG. When ozone wind is generated in the electrode section 30 and flows out from the ozone wind outflow port 52, the inside of the electrode side casing 50 becomes negative pressure, so air also flows in from the side air inflow port 56, and the second electrode section 24 and the first It flows between the electrode part 13 and is turned into ozone wind by corona discharge. In order to flow between the second electrode part 24 and the first electrode part 13 to become ozone wind and exit as the ozone wind outlet 52, the side air inlet 56 is located on the second electrode 20 side with respect to the first electrode 10. It is preferable that the first electrode 10 be formed at a position lower than the first electrode 10 in FIG. Note that the shape and number of the air inlet 54 and the side air inlet 56 are not limited, and are determined as appropriate based on the dimensions of the ozone generator 90, the material of the electrode side casing 50, the design of the split ozone generator 1, etc. . Moreover, even if only the air inlet 54 is formed, only the side air inlet 56 is formed, both are formed, or even if neither is formed, air flows into the ozone generating part 90. do it.

Furthermore, as shown in FIG. 4, a current plate 60 may extend from the inner surface of the electrode-side casing 50. The rectifier plate 60 prevents the ozone wind generated in the electrode section 30 from flowing toward the second electrode 20 side, and also prevents the air flowing in from the side air inlet 56 from flowing into the second electrode 20 side from the first electrode 10, for example, toward the second electrode 20 side. The second electrode of the first electrode 10 is connected to the second electrode of the first electrode 10 from a position closer to the ozone air outlet 52 than the side air inlet 56, from above the side air inlet 56 in FIG. It is preferable that the electrode 20 be formed toward the bottom surface of the first electrode 10 in FIG. In FIG. 4, the current plate 60 extends obliquely, but the inclination of the current plate 60 may be determined as appropriate, and may be parallel to the first electrode 10 and the like.

Further, as shown in FIG. 5, a convex portion 58 may be formed around the air inlet 54 on the outer surface of the electrode side casing 50. The divided ozone generator 1 can be used in any manner, such as by placing it on a table, hanging it on a wall, or hanging it from the user's neck with a string. It's okay. When placed on the table 62, the ozone air outlet 52 is generally directed upward. As a result, the air inlet 54 faces the table 62 and may be blocked by the table 62, or the gap between the table 62 and the electrode-side casing 50 may be narrow, making it difficult for air to flow into the electrode-side casing 50. be. Therefore, a convex portion 58 is formed around the air inlet 54 on the outer surface of the electrode side casing 50 to secure an air flow path between the outer surface of the electrode side casing 50 and the table 62, and It is preferable to encourage air to flow into the area. The shape, quantity, and structure of the convex portion 58 are not particularly limited as long as an air flow path can be secured.

Here, the memory 80 will be explained. The memory 80 records the operating time of the electrode section 30. The electrode section 30 is easily contaminated due to corona discharge, and when dirt accumulates due to long-term operation, the corona discharge becomes weaker due to the dirt, that is, the efficiency of generating ozone wind is reduced. Therefore, the operation time of the electrode section 30 is recorded in the memory 80. The recorded operating time is transmitted to the control device 120 via the connected third terminal 46 and fourth terminal 146. Then, when the recorded driving time exceeds a predetermined threshold value, it is preferable that the control device 120 issues an alarm. The alarm may be by lighting a warning lamp, emitting an alarm sound, or other means. The predetermined threshold value is a continuous operation time of the electrode section 30 determined in terms of design and manufacturing, and may be set in advance by the user. If the recorded operating time exceeds a predetermined threshold value, the control device 120 may stop the operation of the divided ozone generator 1. Here, it is preferable that the memory 80 is placed in the ozone generator 90 separately from the control device 120. This is because in the split type ozone generator 1, when the electrode section 30 becomes dirty, the ozone generating section 90 can be removed from the power supply section 100 as a cassette type and replaced with a new ozone generating section 90. Therefore, the operation time of the electrode section 30 starts to be recorded from zero for a new ozone generating section 90. Therefore, it is preferable to make the memory 80 a part of the ozone generator 90. Further, the memory 80 may measure and record time, or may receive a time signal or a signal that can be converted into time from the control device 120, add it, and record it.

In the description so far, the split type ozone generator 1 includes the memory 80 in the ozone generator 90, and the operating time is transmitted to the control device 120 by connecting the third terminal 46 and the fourth terminal 146. However, the present invention is not limited to this, and the memory 80 may be installed in the power supply unit 100 or may be a part of the control device 120 so that the memory 80 can be reset to zero. In that case, the third terminal 46 and the fourth terminal 146 may not be provided.
