[0009] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, identical or corresponding parts are denoted by the same reference numerals, and their description will not be repeated.

[0010] First, refer to Figure 1 An ion generating system 1 according to an embodiment of the present invention will be described. Figure 1 1 is a diagram showing an ion generating system 1 according to an embodiment of the present invention. Figure 1 As shown, the ion generating system 1 includes an ion generating device 20 .

[0011] The ion generator 20 emits ions. The ions include at least one of positive ions and negative ions. Positive ions are hydrogen ions (H + ) is formed by clustering of multiple water molecules around it (H + (H2O) m (m is an arbitrary integer greater than or equal to zero). In addition, negative ions are, for example, oxygen ions (O2 - ) is formed by clustering of multiple water molecules around it (O2 - (H2O) n (n is an arbitrary integer greater than or equal to zero).

[0012] The ion generator 20 is, for example, an air cleaner having an ion generating function. The ion generator 20 is, for example, an air conditioner having an ion generating function or other air conditioning equipment having an ion generating function.

[0013] The ion generator 20 is placed in a room 30. A user H is present in the room 30. The user H is an example of a "target person." The room 30 is an example of a "space where a target person is present." The room 30 may be a conference room, a waiting room or clinic in a hospital, a classroom or study room in a school or cram school, or a library. The ion generator 20 emits ions into the room 30. The ion generator 20 may release ions toward the user H, toward the upper body of the user H, toward the face of the user H, or may fill the room 30 with ions.

[0014] The ions released from the ion generator 20 reach the user H. Specifically, the user H inhales the ions sent from the ion generator 20 or inhales the air purified by the ions.

[0015] As a result, the blood flow in the blood vessels of user H increases. Specifically, the total hemoglobin concentration in the blood vessels of user H increases. More specifically, the total hemoglobin concentration in the blood vessels of user H increases compared to when ions do not reach user H. In other words, the ion generating device 20 can increase the blood flow in the blood vessels of user H. As a result, parts of user H are activated.

[0016] Specifically, the blood vessels of user H are located in the brain of user H. As a result, blood flow in the brain of user H increases. Consequently, at least one of user H's thinking ability, cognitive function, learning ability, and work ability is improved. In other words, according to the ion generating device 20, at least one of user H's thinking ability, cognitive function, learning ability, and work ability can be further improved by ions.

[0017] More specifically, the blood vessels of the user H are located in the frontal lobe of the user H. As a result, the ion generator 20 increases the blood flow in the frontal lobe of the user H. This improves at least one of the user's thinking ability, cognitive function, learning ability, and work ability.

[0018] More specifically, the blood vessels of the user H are located in the left brain of the user H. As a result, the ion generator 20 increases the blood flow in the left brain of the user H. This improves at least one of the user's thinking ability, cognitive function, learning ability, and work ability.

[0019] More specifically, the blood vessels of the user H are located in the Fp1 of the user H in the 10-20 method. As a result, the ion generator 20 increases the blood flow in the Fp1 of the user H. This improves at least one of the user's thinking ability, cognitive function, learning ability, and work ability.

[0020] More specifically, the concentration of oxyhemoglobin in the blood vessels of the user H increases. More specifically, according to the ion generating device 20 , the concentration of oxyhemoglobin in the blood vessels of the user H increases compared to when ions do not reach the user H.

[0021] More specifically, by allowing the user H to stay in the room 30 for more than one minute, at least one of the user H's thinking ability, cognitive function, learning ability, and work ability is improved. In other words, by allowing the user H to stay in the room 30 for a short period of several minutes, at least one of the user H's thinking ability, cognitive function, learning ability, and work ability is improved.

[0022] Next, refer to Figure 2 The ion generating device 20 will be described in detail. Figure 2 This is a diagram showing the ion generating device 20 of the ion generating system 1 according to this embodiment.

[0023] The ion generating device 20 includes a housing 21 , a duct 22 , an ion generating unit 23 , a blower 24 , a detector 25 , a louver 26 , and an adjuster 27 .

[0024] The housing 21 houses the duct 22 , the ion generating unit 23 , the air blowing unit 24 , the detecting unit 25 , the louver 26 , and the adjusting unit 27 . The housing 21 is an outer shell of the ion generating device 20 .

[0025] The duct 22 guides air and includes a main body 221 , an air inlet 222 , a first air outlet 223 , and a second air outlet 224 .

[0026] The air inlet 222 allows air to flow into the main body 221. Therefore, air flows into the main body 221 from the first direction F1 side through the air inlet 222. The first direction F1 indicates a direction from the outside of the main body 221 toward the inside.

[0027] The main body 221 serves as an air flow path. The main body 221 guides air flowing in from a first direction F1 toward a second direction F2. The second direction F2 refers to the direction from the intake port 222 toward the first outlet 223 or the direction from the intake port 222 toward the second outlet 224. Specifically, the main body 221 guides air flowing in from the intake port 222 toward the first outlet 223 and the second outlet 224.

[0028] First outlet 223 releases air flowing into main body 221 into the atmosphere. Specifically, first outlet 223 releases air in a third direction F3. Third direction F3 is a direction different from the direction in which air inlet 222 is located. Third direction F3 is, for example, the direction from second outlet 224 toward first outlet 223.

[0029] The second outlet 224 releases air flowing into the main body 221 into the atmosphere. Specifically, the second outlet 224 releases air in a fourth direction F4. The fourth direction F4 releases air in a direction different from the third direction F3. For example, the fourth direction F4 is different from the direction in which the air inlet 222 is located. For example, the fourth direction F4 is the direction from the first outlet 223 toward the second outlet 224.

[0030] The ion generating unit 23 generates ions. The ion generating unit 23 includes a pair of discharge units. Each of the discharge units is a needle-shaped or brush-shaped electrode. Each of the discharge units is formed, for example, of a conductive metal. Alternatively, each of the discharge units can be made of, for example, conductive carbon fiber or resin.

[0031] A pair of discharge units discharges. Specifically, a pair of discharge units, to which a high voltage is applied, discharges, generating active species. Active species include ions. For example, a pair of discharge units, to which a high voltage is applied, generates corona discharge. For example, one discharge unit in the pair releases positive ions through discharge. Furthermore, the other discharge unit in the pair releases negative ions through discharge.

[0032] Specifically, one of the pair of discharge sections is fixed to a flat substrate. Furthermore, an induction electrode and a repelling electrode are provided on the surface of the substrate. Furthermore, the back surface of the substrate is fixed to the housing 21. The induction electrode and the repelling electrode are insulated and sealed with resin.

[0033] The induction electrode is an annular electrode, surrounding the discharge portion in a plan view, with the discharge portion located at the center of the annulus. Applying a positive high-voltage pulse to the induction electrode generates a discharge from the discharge portion, generating positive ions. The shape of the induction electrode is not limited to an annular shape.

[0034] The repeller electrode is a circular electrode that surrounds the support, with the support located at the center of the ring. The repeller electrode is designed to achieve a higher ion concentration, and a voltage of the same polarity as the sensing electrode is applied to the repeller electrode.

[0035] Applying a voltage to the sensing electrode generates positive ions from the front end of the conductor. These positive ions migrate along the lines of force from the front end of the conductor toward the sensing electrode. However, applying a voltage of the same polarity to the repeller electrode causes these lines of force to avoid the repeller electrode and circle around it. This facilitates the diffusion of positive ions upward, away from the repeller electrode. This reduces the number of positive ions recovered by the sensing electrode and its surroundings, allowing more positive ions to be released into the airflow.

[0036] Furthermore, the shape of the repeller electrode is not limited to a circular ring. Similarly, one of the discharge sections in a pair of discharge sections is provided with an induction electrode and a repeller electrode. Furthermore, by applying a negative voltage to the induction electrode and repeller electrode in the discharge section, a large number of negative ions can be released into the airflow.

[0037] The ion generating unit 23 may also be capable of switching the output. For example, the ion generating unit 23 may also include an input unit on the surface of the housing 21 for receiving input operations from the user H. In addition, the input unit may also accept remote input operations such as a remote controller. Moreover, the ion generating unit 23 may also increase or decrease the amount of ions released in stages or continuously according to the input operations received by the input unit. For example, the amount of ions released in three stages, namely weak, medium, and strong, may be adjusted. In this case, it is preferred to set the ion generating unit 23 to be able to increase or decrease the amount of ions released in stages or continuously according to the input operations received by the input unit. 3 Output stage of ion concentration of more than 50,000 and make the indoor ion concentration 30 per 1cm 3 Output stage of ion concentration less than 50,000. For example, when the intensity is weak, it can be set to 30 per 1cm 3 The ion concentration is about 12,500, and when the intensity is medium, it is 30 per 1cm indoors. 3 The ion concentration is about 25,000, and when the intensity is strong, it is 30 per 1cm indoors. 3 In addition, according to the ion generating unit 23, regardless of the ion concentration of positive ions and negative ions, it can be set to 1 cm per 30 in the room. 3 There are more than 50,000 ion concentrations.

[0038] The ion generating unit 23 is disposed on the duct 22. Specifically, the ion generating unit 23 is disposed between the suction port 222 and the first discharge port 223. Alternatively, the ion generating unit 23 may be disposed between the suction port 222 and the second discharge port 224.

[0039] The air supply unit 24 generates wind. The air supply unit 24 is, for example, a fan. Examples of fans include a sirocco fan, a propeller fan, a turbo fan, a diagonal flow fan, a linear flow fan (registered trademark), and a cross-flow fan. Specifically, the air supply unit 24 generates wind in a direction from the suction port 222 toward the first discharge port 223. Furthermore, the air supply unit 24 generates wind in a direction from the suction port 222 toward the second discharge port 224. The air supply unit 24 is disposed at the suction port 222.

[0040] The wind generated by the air supply unit 24 contains ions generated by the ion generating unit 23. That is, the wind containing ions is discharged from the first discharge port 223 and the second discharge port 224. Then, the ions are released into the room 30. The ions are released from the ion generating device 20 into the room 30.

[0041] The detection unit 25 detects the user H. Specifically, the detection unit 25 detects an exposed skin portion of the user H. The exposed skin portion may be the user H's face, for example.

[0042] The louver 26 is rotatably mounted on the housing 21. Specifically, the louver 26 is rotatably mounted on the housing 21 about a rotation axis (not shown). The rotation axis of the louver 26 is, for example, substantially parallel to the horizontal direction. Furthermore, the louver 26 is detachably mounted on the housing 21. Furthermore, the louver 26 is mounted on the housing 21 so as to face the first discharge port 223. Furthermore, the louver 26 is mounted on the housing 21 so as to face the second discharge port 224.

[0043] For example, in the first discharge port 223, the louver 26 guides the wind passing through the interior of the duct 22 in a direction corresponding to the rotation angle of the louver 26. That is, the direction of the wind discharged from the first discharge port 223 is the direction corresponding to the rotation angle of the louver 26. Furthermore, for example, in the second discharge port 224, the wind passing through the interior of the duct 22 is guided in a direction corresponding to the rotation angle of the louver 26. That is, the direction of the wind discharged from the second discharge port 224 is the direction corresponding to the rotation angle of the louver 26.

[0044] The adjustment unit 27 adjusts the rotation angle of the louver 26. Specifically, the adjustment unit 27 adjusts the rotation angle of the louver 26 attached to the first outlet 223. Furthermore, the adjustment unit 27 adjusts the rotation angle of the louver 26 attached to the second outlet 224. Thus, the angle of the louver 26 can be adjusted to release air containing ions. As a result, air containing ions can be released in the direction desired by the user H.

[0045] Next, refer to Figure 1 Figure 2 , the ion generating device 20 of this embodiment is described in more detail. Figure 1 and Figure 2 As shown, the ion generating system 1 may include a plurality of ion generating devices 20 .

[0046] The plurality of ion generating devices 20 include a first ion generating device 200A, a second ion generating device 200B, a third ion generating device 200C, and a fourth ion generating device 200D. The first ion generating device 200A to the fourth ion generating device 200D are air cleaners each having an ion generating function.

[0047] The plurality of ion generating devices 20 are arranged at different positions. Figure 2As shown, the second ion generating device 200B to the fourth ion generating device 200D send ions to the user H from a different position than the first ion generating device 200A. That is, the first ion generating device 200A to the fourth ion generating device 200D send ions to the user H respectively. As a result, the concentration of ions around the user H can be increased. For example, by adjusting the air volume or configuration of each of the multiple ion generating devices 20, the concentration of ions in the room 30 can be made to be more than 1 million per 1 cm3. 3 The ion concentration is more than 12,500, preferably 30 per 1 cm 3 More than 25,000 ion concentrations are preferred, with 30 ion concentrations per 1 cm 3 50,000 or more ion concentrations, it is particularly preferred to make the indoor ion concentration 30 per 1 cm 3 Therefore, the blood flow in the blood vessels of the user H can be further increased.

[0048] Furthermore, the ion generator 20 emits ions into the room 30 before the user H uses the room 30. Specifically, the ion generator 20 emits ions into the room 30 a predetermined period before the user H performs work. The predetermined period is, for example, one minute. Therefore, while the user H is performing work, the blood flow in the user's blood vessels can be further increased. For example, this can improve at least one of the user's thinking ability, cognitive function, learning ability, and work performance.

[0049] When the first ion generating device 200A sends ions to the user H, the second ion generating device 200B The fourth ion generating device 200D also emits ions toward the user H. Therefore, when the user H is working, the blood flow in the blood vessels of the user H can be further increased.

[0050] Next, refer to Figure 3 , the processing executed by the motion system 1 involved in this embodiment is described. Figure 3 FIG. 1 is a diagram showing the processing performed by the motion system 1 according to this embodiment. Figure 3 As shown, the process includes steps S101 to S104.

[0051] In step S101, the ion generating unit 23 of the ion generating device 20 starts generating ions. The process proceeds to step S102.

[0052] In step S102, the blower 24 of the ion generator 20 starts generating wind. The wind generated by the blower 24 contains ions generated by the ion generator 23. The process proceeds to step S103.

[0053] In step S103, the ion generating unit 23 of the ion generating device 20 ends generating ions, and the process proceeds to step S226.

[0054] In step S104, the air blowing unit 24 of the ion generating device 20 stops generating air. The process ends.

[0055] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the above-mentioned embodiments and can be implemented in various ways without departing from the main purpose thereof. In addition, various inventions can be formed by appropriately combining the multiple components disclosed in the above-mentioned embodiments. For example, some components can be deleted from all the components shown in the embodiments. In addition, the components of different embodiments can also be appropriately combined. In the accompanying drawings, each component is schematically shown as a main body for easy understanding, and for the convenience of drawing, the thickness, length, quantity, etc. of each component shown in the drawings may be different from the actual ones. In addition, the material, shape, size, etc. of each component shown in the above-mentioned embodiments are only examples and are not particularly limited. Various changes can be made within the scope that does not substantially depart from the effect of the present invention.

[0056] (1) In the ion generating system 1 of this embodiment, the user H performs an operation in the room 30 where the ion generating device 20 is installed. However, the present invention is not limited thereto. For example, the room 30 may be the room of a mobile object. When the ion generating system 1 is installed in the mobile object, the operation is the operation of driving the mobile object.

[0057] Examples of the mobile object include cars, trains, ships, and airplanes. Furthermore, seats are provided in the interior 30 of the mobile object. A user H is seated on the seat. The user H operates the mobile object. The ion generator 20 can increase blood flow in the blood vessels of the user H operating the mobile object.

[0058] (2) The ion generating device 20 of the ion generating system 1 of this embodiment can change the air volume based on the heart rate of the user H. The heart rate of the user H can be obtained by a heart rate monitor. The heart rate monitor and the ion generating device 20 can communicate via wired or wireless communication. That is, the heart rate obtained by the heart rate monitor is sent to the ion generating device 20. The air supply unit 24 of the ion generating device 20 that has obtained the heart rate of the user H changes the air volume based on the obtained heart rate. In other words, the air supply unit 24 changes the air volume according to the obtained heart rate. Specifically, the higher the obtained heart rate, the more the air supply unit 24 increases the air volume. Therefore, the air volume of the air supply unit 24 can be changed according to the heart rate of the user H. As a result, when the heart rate increases due to exercise, the air volume can be increased. In addition, the air supply unit 24 supplies air, and the ion generating unit 23 releases ions. Therefore, the air generated by the air supply unit 24 contains ions. In other words, as the air volume increases, the amount of ions delivered can also increase. As a result, when the heart rate rises due to exercise, wind containing ions can be sent to the user H.

[0059] Furthermore, the adjustment unit 27 of the ion generator 20 can also adjust the rotation angle of the louver 26 in response to an increase in heart rate. Thus, the angle of the louver 26 can be adjusted to release wind containing ions. As a result, wind containing ions can be released in a direction desired by the user H with increased volume. [Example]

[0060] Next, refer to Figures 4 to 9 The present invention will be described in detail based on the following examples, but the present invention is not limited to the following examples.

[0061] [Example] First, refer to Figure 4 , describing the experimental steps using the ion generating system 1 of the present invention. Figure 4 This diagram shows the experimental procedure using the ion generating system according to the present invention. The experimental procedure includes the first step PC1 to the fifth step PC5. Twenty-five users H performed the work according to the experimental procedure. The 25 users H were male students.

[0062] The first step PC1 is a step in which the user H wears an electroencephalogram (ENIRS) (Wearable Optical Topology WOT-202, manufactured by Neu Corporation) as the electroencephalogram. The NIRS acquires the oxygenated hemoglobin concentration and the deoxygenated hemoglobin concentration in Fp1 and Fp2 of the user H's brain every second, for example, using the 10-20 method.

[0063] The second step PC2 represents a step in which the user H is quiet in the room 30. The user H is quiet in the room 30 for 1 minute. In the room 30, ions are sent to the user H. In the room 30, every 1 cm 3 The ion concentration becomes 100,000 or more. In addition, the user H does not know that the wind containing ions is sent out from the ion generating device 20.

[0064] The third step PC3 is a step in which the user H performs an operation. Specifically, the user H performs TMT test B. The user H repeats TMT test B 5 times for 1 minute. In the room 30, ions are sent to the user H. In the room 30, ions are sent to the user H for every 1 cm 3 The ion concentration becomes 100,000 or more. In addition, the user H does not know that the wind containing ions is sent out from the ion generating device 20.

[0065] The fourth step PC4 shows the step of user H staying quiet in room 30. It shows the sequence of user H staying quiet in room 30. In room 30, ions are sent to user H. In room 30, ions are sent to user H. 3 The ion concentration becomes 100,000 or more. In addition, the user H does not know that the wind containing ions is sent out from the ion generating device 20.

[0066] The fifth step PC5 represents a step in which the user H takes off the electroencephalogram monitor.

[0067] [Comparative Example] In the comparative example, in the second step PC2 , the third step PC3 , and the fourth step PC4 of the embodiment, ions are not sent to the user H instead of being sent to the user H. In the room 30 , the ion concentration is zero.

On the other hand, the average value of the change in total hemoglobin concentration in the Comparative Example is "approximately 0.12." The average value of the change in total hemoglobin concentration in the Example is larger than that in the Comparative Example.

[0073] Furthermore, the experimental result PTB2 of the Example showed a numerically larger result than the experimental result CPB2 of the Comparative Example. Specifically, the average change in the oxyhemoglobin concentration of the Example was approximately 0.26. Meanwhile, the average change in activity level of the Comparative Example was approximately 0.17. The average change in the oxyhemoglobin concentration of the Example was larger than that of the Comparative Example.
