Modes for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figures, the same or corresponding parts are denoted by the same reference numerals and the description will not be repeated. Also, for the sake of convenience of explanation, a three-dimensional orthogonal coordinate system (X, Y, Z) is appropriately shown in the drawings. And in the figures, the X-axis and the Y-axis are parallel to the horizontal direction, and the Z-axis is parallel to the vertical direction. Also, in this specification, a plan view means viewing an object from directly above vertically.

[0009] [Embodiment 1] Referring to FIGS. 1 to 5, the air blowing system 1 according to Embodiment 1 of the present invention will be described. First, the air blowing system 1 will be described with reference to FIG. 1. FIG. 1 is a plan view showing the air blowing system 1. As shown in FIG. 1, as an example, the air blowing system 1 is installed inside the moving body VC. The moving body VC is movable by the power of a power source. The power source is, for example, an engine or a motor. In the example of FIG. 1, the moving body VC is a bus. However, the moving body VC is not particularly limited as long as it moves with people on board, and may be, for example, a ship, an airplane, or a vehicle (for example, a railway or a passenger car). The railway is, for example, a train, a locomotive, or a tram.

[0010] The moving body VC includes at least one first seat C1, a door VD, and a steering mechanism 10. In the example of FIG. 1, the moving body VC includes a plurality of first seats C1. People get on and off from the door VD. The steering mechanism 10 is a mechanism for steering the moving body VC. The steering mechanism 10 includes, for example, a steering wheel.

[0011] The plurality of first seats C1 are installed along the first direction D1. In the example of FIG. 1, the first direction D1 indicates a direction along the traveling direction of the moving body VC. For example, the first direction D1 is substantially parallel to the traveling direction of the moving body VC. Also, in the example of FIG. 1, the first direction D1 indicates a direction along the longitudinal direction of the moving body VC. For example, the first direction D1 is substantially parallel to the longitudinal direction of the moving body VC. The first direction D1 corresponds to an example of the "predetermined direction".

[0012] Each first seat C1 includes a single first seating area SA1, a plurality of first seating areas SA1, a single third seating area SA3, or a plurality of third seating areas SA3. The plurality of first seating areas SA1 are arranged at intervals along the first direction D1. The plurality of third seating areas SA3 are arranged at intervals along the first direction D1. The first seating area SA1 and the third seating area SA3 are alternately arranged along the first direction D1. People can be seated in the first seating area SA1 and the third seating area SA3.

[0013] The moving body VC preferably further includes at least one second seat C2. In the example of FIG. 1, the moving body VC includes a plurality of second seats C2. The plurality of second seats C2 are installed along the first direction D1.

[0014] Each second seat C2 includes a single second seating area SA2, a plurality of second seating areas SA2, a single fourth seating area SA4, or a plurality of fourth seating areas SA4. The plurality of second seating areas SA2 are arranged at intervals along the first direction D1. The plurality of fourth seating areas SA4 are arranged at intervals along the first direction D1. The second seating area SA2 and the fourth seating area SA4 are alternately arranged along the first direction D1. People can be seated in the second seating area SA2 and the fourth seating area SA4.

[0015] In the example in Figure 1, the first seating area SA1 and the fourth seating area SA4 face each other in the second direction D2. The second seating area SA2 and the third seating area SA3 face each other in the second direction D2. The second direction D2 intersects the first direction D1. In the example in Figure 1, the second direction D2 is approximately perpendicular to the first direction D1. Also, the second direction D2 is approximately parallel to the horizontal direction.

[0016] The blowing system 1 comprises at least one first ion delivery device 100. In the example shown in Figure 1, the blowing system 1 comprises a plurality of first ion delivery devices 100. The first ion delivery devices 100 deliver air containing ions. Specifically, each of the plurality of first ion delivery devices 100 delivers air containing ions toward a plurality of first seating areas SA1. In this specification, ions are, for example, particulate ions produced by applying a high voltage and causing an electrical discharge. The ions may include, for example, negatively charged ions (negative ions), positively charged ions (positive ions), or both negative and positive ions.

[0017] Hereinafter, the "ion-containing air" discharged by the first ion discharger 100 may be referred to as the first ion wind F1.

[0018] The blowing system 1 preferably further comprises at least one second ion delivery device 200. In the example shown in Figure 1, the blowing system 1 comprises a plurality of second ion delivery devices 200. The second ion delivery devices 200 deliver air containing ions. Specifically, each of the plurality of second ion delivery devices 200 delivers air containing ions toward a plurality of second seating areas SA2.

[0019] Hereinafter, the "ion-containing air" discharged by the second ion delivery device 200 may be referred to as the second ion wind F2.

[0020] The first ion delivery device 100 and the second ion delivery device 200 are installed above the internal space of the mobile body VC. Specifically, the first ion delivery device 100 and the second ion delivery device 200 are installed above the first seat C1 and the second seat C2. In other words, the first ion delivery device 100 and the second ion delivery device 200 are installed above the first seating area SA1 to the fourth seating area SA4. Details of the arrangement of the first ion delivery device 100 and the second ion delivery device 200 will be described later.

[0021] Next, the first ion delivery device 100 will be described with reference to Figure 2. Figure 2 is a diagram of the first ion delivery device 100. In Figure 2, a schematic cross-section of the first ion delivery device 100 is shown. As shown in Figure 2, the first ion delivery device 100 includes a first generation unit 101, a first air blowing unit 105, a first housing 110, and a first duct 120. The first ion delivery device 100 also has a first suction port 131 and a first outlet port 132.

[0022] The first generation unit 101, the first air blowing unit 105, and the first duct 120 are housed in the first housing 110.

[0023] The first generating unit 101 generates ions. The first generating unit 101 generates ions of first polarity and / or second polarity. The second polarity exhibits the opposite polarity to the first polarity. The first polarity ion is, for example, a positive ion. The second polarity ion is, for example, a negative ion. In this specification, ions can be used to suppress the activity of, for example, viruses and bacteria in the air, viruses and bacteria attached to objects, and viruses and bacteria attached to people. In addition, for example, ions can be used for sterilization, deodorization, static electricity suppression, and / or skin moisturizing.

[0024] Specifically, the first generation unit 101 includes a first electrode 102 and a second electrode 103. The first electrode 102 and the second electrode 103 are arranged at a distance from each other. The first electrode 102 generates ions of first polarity by discharging. The second electrode 103 generates ions of second polarity by discharging. The first generation unit 101 also includes a power supply circuit (not shown) for discharging the first electrode 102 and the second electrode 103.

[0025] The first duct 120 extends from the first air supply unit 105 to the first air outlet 132. The first duct 120 is inclined diagonally downward with respect to the horizontal direction.

[0026] The first air outlet 132 is located at the bottom of the first housing 110. The first air outlet 132 is angled downwards with respect to the horizontal. The first suction port 131 is located on the side of the first housing 110. The first suction port 131 is oriented horizontally.

[0027] The first blower unit 105 blows air along the first duct 120 and blows the air out from the first outlet 132. Specifically, the first blower unit 105 draws in air from the first intake port 131 and blows the drawn-in air through the first duct 120 and out from the first outlet 132. The first blower unit 105 is, for example, a centrifugal fan. A centrifugal fan includes, for example, a motor and an impeller.

[0028] The first electrode 102 and the second electrode 103 protrude into the first duct 120. Therefore, first polarity ions and second polarity ions are generated in the first duct 120. As a result, the first air blower 105 blows out a first ionized wind F1, which is air containing ions, from the first outlet 132. Specifically, the first air blower 105 blows out the first ionized wind F1 diagonally downward from the first outlet 132. In Embodiment 1, the first ionized wind F1 contains first polarity ions and second polarity ions.

[0029] The discharge angle θ of the first ion wind F1 from the first blower unit 105 is, for example, approximately 45 degrees or more and approximately 65 degrees or less downward with respect to the horizontal. Typically, the discharge angle θ is approximately 55 degrees. For example, the discharge angle θ is the discharge angle of the first duct 120 when the first duct 120 is inclined downward with respect to the horizontal. In this case, the discharge angle indicates the angle with respect to the horizontal. For example, the discharge angle θ is not particularly limited and is set appropriately based on the size of the internal space of the mobile body VC, the size and arrangement of the first seat C1 and the second seat C2, and the size and arrangement of the first seating area SA1 to the fourth seating area SA4. Furthermore, regarding the discharge angle θ, the shape of the first outlet 132 itself may be designed to deliver at the target angle, or a wind direction adjustment plate may be provided at the first outlet 132 and the wind direction adjustment plate may be adjusted appropriately to achieve the target angle.

[0030] The configuration of the second ion delivery device 200 shown in Figure 1 is the same as the configuration of the first ion delivery device 100 described with reference to Figure 2.

[0031] Specifically, as shown in Figure 2, the second ion delivery device 200 includes a second generation unit 201, a second air blowing unit 205, a second housing 210, and a second duct 220. The second ion delivery device 200 also has a second intake port 231 and a second outlet port 232.

[0032] The second generation unit 201, the second air blowing unit 205, and the second duct 220 are housed in the second housing 210.

[0033] The second generating unit 201 generates ions. The second generating unit 201 generates ions of first polarity and / or second polarity. Specifically, the second generating unit 201 includes a third electrode 202 and a fourth electrode 203. The third electrode 202 and the fourth electrode 203 are spaced apart. The third electrode 202 generates ions of first polarity by discharging. The fourth electrode 203 generates ions of second polarity by discharging. Otherwise, the configuration of the second generating unit 201 is the same as that of the first generating unit 101.

[0034] The second duct 220 extends from the second air supply unit 205 to the second air outlet 232. The second duct 220 is inclined diagonally downward with respect to the horizontal direction.

[0035] The second air outlet 232 is located at the bottom of the second housing 210. The second air outlet 232 is angled downwards with respect to the horizontal. The second suction port 231 is located on the side of the second housing 210. The second suction port 231 is oriented horizontally.

[0036] The second air blower 205 blows air along the second duct 220 and blows the air out from the second outlet 232. Specifically, the second air blower 205 draws in air from the second intake port 231 and blows the drawn-in air through the second duct 220 and out from the second outlet 232. Otherwise, the configuration of the second air blower 205 is the same as that of the first air blower 105.

[0037] The third electrode 202 and the fourth electrode 203 protrude into the second duct 220. Therefore, first polarity ions and second polarity ions are generated in the second duct 220. As a result, the second air blower 205 blows out a second ionized wind F2, which is air containing ions, from the second outlet 232. Specifically, the second air blower 205 blows out the second ionized wind F2 diagonally downward from the second outlet 232. In Embodiment 1, the second ionized wind F2 contains both first polarity ions and second polarity ions.

[0038] The discharge angle θ of the second ion wind F2 from the second blower unit 205 is, for example, approximately 45 degrees or more and approximately 65 degrees or less downward with respect to the horizontal. Typically, the discharge angle θ is approximately 55 degrees. For example, the discharge angle θ is the discharge angle of the second duct 220 when the second duct 220 is inclined downward with respect to the horizontal. In this case, the discharge angle indicates the angle with respect to the horizontal. Otherwise, the discharge angle θ of the second ion wind F2 is the same as the discharge angle θ of the first ion wind F1.

[0039] Next, with reference to Figure 3, the airflow state of the first ion wind F1 from the first ion delivery device 100 will be explained. Figure 3 is a schematic cross-sectional view along the line III-III in Figure 1. In Figure 3, the first ion wind F1 is shown by dense dot hatching.

[0040] As shown in Figure 3, for example, the first ion delivery device 100 is installed on the ceiling surface 50 of the mobile body VC. Alternatively, for example, the first ion delivery device 100 may be installed between the horizontal bar supporting the handrail and the ceiling surface 50. Alternatively, for example, the first ion delivery device 100 may be installed on the vertical bar supporting the horizontal bar supporting the handrail. In this case, the vertical bar is fixed between the ceiling surface 50 and the horizontal bar.

[0041] The first blower unit 105 of the first ion delivery device 100 delivers a first ion wind F1 toward the first seating area SA1. The first seating area SA1 is located diagonally below the first ion delivery device 100. Therefore, according to Embodiment 1, in a cross-sectional view, the first blower unit 105 delivers the first ion wind F1 diagonally downward toward the first seating area SA1. As a result, ions can be effectively blown not only on seated people HM1 but also on standing people HM2. For example, the ion concentration in the first ion wind F1 from the first ion delivery device 100 to the first seating area SA1 is 30,000 ions / cm³. 3 , and so on. Furthermore, as long as the first ion wind F1 reaches the first seating region SA1, the wind speed of the first ion wind F1 is not particularly limited.

[0042] In this specification, a cross-sectional view refers to viewing an object cut by a plane substantially perpendicular to the first direction D1 (Figure 1).

[0043] Specifically, in a cross-sectional view, the first air blower 105 sends out the first ion wind F1 diagonally downward with respect to the second direction D2, thereby causing the first ion wind F1 to reach the first seating area SA1.

[0044] Next, with reference to Figure 4, the airflow state of the second ion wind F2 from the second ion delivery device 200 will be explained. Figure 4 is a schematic cross-sectional view along the line IV-IV in Figure 1. In Figure 4, the second ion wind F2 is shown by dense dot hatching.

[0045] As shown in Figure 4, for example, the second ion delivery device 200 is installed on the ceiling surface 50 of the mobile unit VC. Other installation examples for the second ion delivery device 200 are the same as those for the first ion delivery device 100.

[0046] The second air blower 205 of the second ion delivery device 200 delivers a second ion wind F2 toward the second seating area SA2. The second seating area SA2 is located diagonally below the second ion delivery device 200. Therefore, according to Embodiment 1, in a cross-sectional view, the second air blower 205 delivers the second ion wind F2 diagonally downward toward the second seating area SA2. As a result, ions can be effectively blown not only on seated people HM3 but also on standing people HM4. For example, the ion concentration in the second ion wind F2 from the second ion delivery device 200 to the second seating area SA2 is 30,000 ions / cm³. 3 Furthermore, as long as the second ion wind F2 reaches the second seating region SA2, the wind speed of the second ion wind F2 is not particularly limited.

[0047] Specifically, in a cross-sectional view, the second air blower 205 sends out the second ion wind F2 diagonally downward with respect to the second direction D2, thereby causing the second ion wind F2 to reach the second seating region SA2.

[0048] Furthermore, in Embodiment 1, as shown in Figure 4, the first ion wind F1 from the first ion delivery device 100 shown in Figures 1 and 3 reaches the third seating area SA3 of the first seat C1. Therefore, ions can be blown onto a person seated in the third seating area SA3 by the first ion wind F1. The ion concentration of the first ion wind F1 in the third seating area SA3 is lower than the ion concentration of the second ion wind F2 in the second seating area SA2. For example, the ion concentration of the first ion wind F1 in the third seating area SA3 is 23,000 ions / cm³. 3 In Figure 4, the first ionic wind F1 is shown by sparse dot hatching.

[0049] Similarly, as shown in Figure 3, the second ion wind F2 from the second ion delivery device 200 shown in Figures 1 and 4 reaches the fourth seating area SA4 of the second seat C2. Therefore, ions can be blown onto a person seated in the fourth seating area SA4 by the second ion wind F2. The ion concentration of the second ion wind F2 in the fourth seating area SA4 is lower than the ion concentration of the first ion wind F1 in the first seating area SA1. For example, the ion concentration of the second ion wind F2 in the fourth seating area SA4 is 23,000 ions / cm³. 3 In Figure 3, the second ion wind F2 is shown by sparse dot hatching.

[0050] Referring again to Figure 1, the arrangement of the first ion delivery device 100 and the second ion delivery device 200 will be explained.

[0051] As shown in Figure 1, in a plan view, the first ion delivery device 100 is installed on the side of the second seating area SA2 that is closer to the second ion delivery device 200. Also, in a plan view, the second ion delivery device 200 is installed on the side of the first seating area SA1 that is closer to the first ion delivery device 100.

[0052] Specifically, in a plan view, the first ion delivery device 100 and the second ion delivery device 200 are positioned obliquely to each other with respect to the first direction D1. Therefore, collisions between the first ion wind F1 and the second ion wind F2 can be suppressed. As a result, according to Embodiment 1, neutralization of ions between the first ion wind F1 and the second ion wind F2 can be suppressed.

[0053] In other words, in a plan view, the first ion delivery device 100 and the second ion delivery device 200 are positioned obliquely to each other with respect to the second direction D2.

[0054] To put it another way, in a plan view, the first ion discharger 100 is positioned diagonally from the second ion discharger 200 with respect to the direction of the second ion wind F2. In addition, in a plan view, the second ion discharger 200 is positioned diagonally from the first ion discharger 100 with respect to the direction of the first ion wind F1.

[0055] In a plan view, the first air blower 105 blows a first ion wind F1 toward the first seating area SA1 along the second direction D2. Also in a plan view, the second air blower 205 blows a second ion wind F2 toward the second seating area SA2 along the second direction D2. Furthermore, in a plan view, the directions of the first ion wind F1 and the second ion wind F2 are opposite to each other. Therefore, in a plan view, the directions of the first ion wind F1 and the second ion wind F2 are not moving away from each other, but rather moving towards each other.

[0056] Referring to Figure 1, the details of the arrangement of the first ion delivery device 100 and the second ion delivery device 200 will be described.

[0057] As shown in Figure 1, the multiple first ion delivery devices 100 are installed at intervals along the first direction D1. In the example in Figure 1, the multiple first ion delivery devices 100 are installed at equal intervals along the first direction D1.

[0058] Furthermore, the multiple second ion delivery devices 200 are installed at intervals along the first direction D1. In the example shown in Figure 1, the multiple second ion delivery devices 200 are installed at equal intervals along the first direction D1.

[0059] Specifically, a first row L1 consisting of multiple first ion delivery devices 100 extends along a first direction D1. In the example shown in Figure 1, in a plan view, the multiple first ion delivery devices 100 in the first row L1 are arranged in a nearly straight line. However, for example, in a plan view, the multiple first ion delivery devices 100 in the first row L1 may be arranged in a zigzag pattern.

[0060] Furthermore, a second row L2 consisting of multiple second ion delivery devices 200 extends along the first direction D1. In the example shown in Figure 1, in a plan view, the multiple second ion delivery devices 200 in the second row L2 are arranged in a nearly straight line. However, for example, in a plan view, the multiple second ion delivery devices 200 in the second row L2 may be arranged in a zigzag pattern.

[0061] The first row L1 and the second row L2 face each other in the second direction D2. In a plan view, the first ion discharger 100 and the second ion discharger 200 that are closest to each other between the first row L1 and the second row L2 are offset from each other in the first direction D1. In other words, in a plan view, the first ion discharger 100 and the second ion discharger 200 are installed alternately along the first direction D1 between the first row L1 and the second row L2. To put it another way, in a plan view, the first ion discharger 100 and the second ion discharger 200 are installed in a zigzag pattern along the first direction D1. To put it yet another way, in a plan view, the first ion discharger 100 and the second ion discharger 200 are installed in a staggered pattern.

[0062] Therefore, according to Embodiment 1, ions can be effectively blown onto people riding on the mobile vehicle VC while suppressing an increase in the number of ion delivery devices (first ion delivery device 100 and second ion delivery device 200). In addition, collisions between the first ion wind F1 and the second ion wind F2 can be suppressed, thus preventing ions from being neutralized between the first ion wind F1 and the second ion wind F2.

[0063] Furthermore, in Embodiment 1, the mobile body VC has a passage AS. The passage AS extends along a first direction D1. The first seat C1 and the second seat C2 face each other in the second direction D2, with the passage AS in between. The first seating area SA1 and the fourth seating area SA4 face each other in the second direction D2, with the passage AS in between. The second seating area SA2 and the third seating area SA3 face each other in the second direction D2, with the passage AS in between.

[0064] In other words, in a plan view, the first seating area SA1 and the third seating area SA3 are located on one side of the aisle AS. One side of the aisle AS refers to one side of the aisle AS in the second direction D2. Also, in a plan view, the second seating area SA2 and the fourth seating area SA4 are located on the other side of the aisle AS. The other side of the aisle AS refers to the other side of the aisle AS in the second direction D2.

[0065] In Embodiment 1, the first ion delivery device 100 can effectively blow ions onto both person HM2 in the passage AS and person HM1 seated in the first seating area SA1 (Figure 3). Furthermore, the second ion delivery device 200 can effectively blow ions onto both person HM4 in the passage AS and person HM3 seated in the second seating area SA2 (Figure 4).

[0066] Furthermore, in Embodiment 1, the first ion delivery device 100 is installed above the fourth seating area SA4, which is adjacent in the first direction D1 to the second seating area SA2 to which the second ion wind F2 is blown. In addition, the second ion delivery device 200 is installed above the third seating area SA3, which is adjacent in the first direction D1 to the first seating area SA1 to which the first ion wind F1 is blown. Therefore, collisions between the first ion wind F1 and the second ion wind F2 can be effectively suppressed, and thus the neutralization of ions between the first ion wind F1 and the second ion wind F2 can be effectively suppressed.

[0067] Specifically, in a plan view, the first ion delivery device 100 is installed closer to the first seating area SA1 than to the position directly above the fourth seating area SA4. Therefore, the first ion delivery device 100 can reliably deliver the first ion wind F1 to the first seating area SA1. Also, in a plan view, the second ion delivery device 200 is installed closer to the second seating area SA2 than to the position directly above the third seating area SA3. Therefore, the second ion delivery device 200 can reliably deliver the second ion wind F2 to the second seating area SA2.

[0068] Furthermore, in Embodiment 1, multiple first ion dischargers 100 and multiple second ion dischargers 200 are installed in the mobile body VC. Therefore, in the mobile body VC, which is prone to becoming filled with bacteria or viruses, the ions blown by the first ion dischargers 100 and the second ion dischargers 200 (first ion wind F1 and second ion wind F2) can suppress the activity of viruses and bacteria. Also, for example, since odors tend to accumulate in the mobile body VC, the ions blown by the first ion dischargers 100 and the second ion dischargers 200 can effectively deodorize the body. Furthermore, for example, the ions blown by the first ion dischargers 100 and the second ion dischargers 200 can effectively suppress static electricity generated in the mobile body VC.

[0069] Next, with reference to Figure 5, the arrangement of the first electrode 102 and the second electrode 103 of the first ion delivery device 100, and the third electrode 202 and the fourth electrode 203 of the second ion delivery device 200 will be described.

[0070] Figure 5 is a plan view showing the details of the arrangement of the first ion delivery device 100 and the second ion delivery device 200. As shown in Figure 5, in plan view, between the first ion delivery device 100A and the second ion delivery device 200A, the first electrode 102 that generates first polarity ions is located closer to the third electrode 202 that generates first polarity ions than the second electrode 103 that generates second polarity ions. The first ion delivery device 100A and the second ion delivery device 200A are adjacent to each other at an angle with respect to the first direction D1. In addition, between the first ion delivery device 100A and the second ion delivery device 200A, the second electrode 103 that generates second polarity ions is located further away from the third electrode 202 that generates first polarity ions than the first electrode 102 that generates first polarity ions. Therefore, according to Embodiment 1, the neutralization of first polarity ions and second polarity ions can be effectively suppressed.

[0071] Specifically, in a plan view, between the second ion delivery device 200A and one of the two first ion delivery devices 100A and 100B, the first electrode 102 is located closer to the third electrode 202 than the second electrode 103, and the second electrode 103 is located further away from the third electrode 202 than the first electrode 102. Therefore, according to Embodiment 1, the neutralization of first polarity ions and second polarity ions can be effectively suppressed. The second ion delivery device 200A is located diagonally adjacent to the two first ion delivery devices 100A and 100B that are adjacent in the first direction D1.

[0072] In addition, in a plan view, between the second ion delivery device 200A and the other first ion delivery device 100B of the two first ion delivery devices 100A and 100B, the second electrode 103 is located closer to the fourth electrode 203 than the first electrode 102, and the first electrode 102 is located further away from the fourth electrode 203 than the second electrode 103. Therefore, according to Embodiment 1, the neutralization of first polarity ions and second polarity ions can be effectively suppressed.

[0073] Furthermore, in the multiple first ion delivery devices 100 constituting the first column L1, the first electrode 102 and the second electrode 103 are arranged alternately along the first direction D1. Similarly, in the multiple second ion delivery devices 200 constituting the second column L2, the third electrode 202 and the fourth electrode 203 are arranged alternately along the first direction D1. The direction from the first electrode 102 to the second electrode 103 is opposite to the direction from the third electrode 202 to the fourth electrode 203.

[0074] More specifically, between the first ion delivery device 100A and the second ion delivery device 200A, the distance D13 between the first electrode 102 and the third electrode 202 is shorter than the distance D23 between the second electrode 103 and the third electrode 202. In addition, between the first ion delivery device 100B and the second ion delivery device 200A, the distance D24 between the second electrode 103 and the fourth electrode 203 is shorter than the distance D14 between the first electrode 102 and the fourth electrode 203.

[0075] More specifically, in a side view, the first electrode 102 and the third electrode 202 are adjacent in the first direction D1. Also, in a side view, the fourth electrode 203 and the second electrode 103 are adjacent in the first direction D1.

[0076] In this specification, a side view refers to viewing the object from a second direction D2.

[0077] (Variation 1) Referring to Figure 6, the blower system 1 according to Modification 1 of Embodiment 1 will be described. The positions of the first ion delivery device 100 and the second ion delivery device 200 differ between Modification 1 and Embodiment 1 described with reference to Figure 1. The differences between Modification 1 and Embodiment 1 will be mainly described below.

[0078] Figure 6 is a plan view showing the blowing system 1 according to modified example 1. As shown in Figure 6, the first ion delivery device 100 is installed directly above the fourth seating area SA4. The second ion delivery device 200 is installed directly above the third seating area SA3.

[0079] (Modification 2) Next, with reference to Figures 1 to 4 and Figure 7, the air blowing system 1 according to Modification 2 of Embodiment 1 will be described. Modification 2 and Embodiment 1, described with reference to Figure 1, differ mainly in that the first ion delivery device 100 delivers the first ion wind F1 in three directions, and the second ion delivery device 200 delivers the second ion wind F2 in three directions. The differences between Modification 2 and Embodiment 1 will be mainly described below.

[0080] Figure 7 is a plan view showing the details of the arrangement of the first ion delivery device 100 and the second ion delivery device 200 according to a modified example 2 of Embodiment 1. As shown in Figure 7, the mobile body VC is equipped with a plurality of first ion delivery devices 100 and a plurality of second ion delivery devices 200. The first ion delivery device 100 delivers a first ion wind F1 to the first seating area SA1 and the third seating area SA3. The second ion delivery device 200 delivers a second ion wind F2 to the second seating area SA2 and the fourth seating area SA4.

[0081] In other words, the first ion delivery device 100 can effectively blow ions onto a person seated in the third seating area SA3. In addition, the second ion delivery device 200 can effectively blow ions onto a person seated in the fourth seating area SA4. Therefore, the difference in concentration of the first ion wind F1 in the third seating area SA3 and the first ion wind F1 in the first seating area SA1 can be reduced, and the difference in concentration of the second ion wind F2 in the fourth seating area SA4 and the second ion wind F2 in the second seating area SA2 can be reduced. As a result, the ion concentration near the seating areas can be made uniform.

[0082] Each of the multiple first ion delivery devices 100 has multiple first outlets 132 as shown in Figure 2. For example, one first ion delivery device 100 has three first outlets 132. In other words, the first ion delivery device 100 delivers multiple first ion winds F. Specifically, the first ion delivery device 100 delivers a first ion wind F1A, a first ion wind F1B, and a first ion wind F1C.

[0083] As shown in Figure 3, in a cross-sectional view, the first air blower 105 sends out the first ion wind F1B diagonally downward with respect to the second direction D2, thereby causing the first ion wind F1B to reach the third seating area SA3. As shown in Figure 7, in a plan view, the first ion wind F1B is sent out from the first air blower 105 toward the third direction D3. The third direction D3 is the direction from the door VD shown in Figure 1 toward the control mechanism 10.

[0084] As shown in Figure 3, in a cross-sectional view, the first air blower 105 sends out the first ion wind F1C diagonally downward with respect to the second direction D2, thereby causing the first ion wind F1C to reach the third seating area SA3. As shown in Figure 7, in a plan view, the first ion wind F1C is sent out from the first air blower 105 toward the fourth direction D4. The fourth direction D4 is the direction from the control mechanism 10 shown in Figure 1 toward the door VD. The fourth direction D4 is the opposite direction to the third direction D3.

[0085] As shown in Figure 3, in a cross-sectional view, the first air blower 105 sends out the first ion wind F1A diagonally downward with respect to the second direction D2, thereby causing the first ion wind F1A to reach the first seating area SA1. As shown in Figure 7, in a plan view, the first ion wind F1A is sent out from the first air blower 105 toward the fifth direction D5. The fifth direction D5 indicates the direction from the second seat C2 toward the first seat C1.

[0086] Each of the multiple second ion delivery devices 200 has multiple second outlets 232 as shown in Figure 2. For example, one second ion delivery device 200 has three second outlets 232. In other words, the second ion delivery device 200 delivers multiple second ion winds. Specifically, the second ion delivery device 200 delivers a second ion wind F2A, a second ion wind F2B, and a second ion wind F2C.

[0087] As shown in Figure 4, in a cross-sectional view, the second air blower 205 sends out the second ion wind F2A diagonally downward with respect to the second direction D2, thereby causing the second ion wind F2A to reach the second seating area SA2. As shown in Figure 7, in a plan view, the second ion wind F2A is sent out from the second air blower 205 in the sixth direction D6. The sixth direction D6 is the direction from the first seat C1 to the second seat C2. The sixth direction D6 is the opposite direction to the fifth direction D5.

[0088] As shown in Figure 4, in a cross-sectional view, the second air blower 205 sends out the second ion wind F2B diagonally downward with respect to the second direction D2, thereby causing the second ion wind F2B to reach the fourth seating area SA4. As shown in Figure 7, in a plan view, the second ion wind F2B is sent out from the second air blower 205 toward the third direction D3.

[0089] As shown in Figure 4, in a cross-sectional view, the second air blower 205 sends out the second ion wind F2C diagonally downward with respect to the second direction D2, thereby causing the second ion wind F2C to reach the fourth seating area SA4. As shown in Figure 7, in a plan view, the second ion wind F2C is sent out from the first air blower 105 toward the fourth direction D4.

[0090] [Embodiment 2] Next, the second embodiment of the blower system 1 will be described with reference to Figures 2 to 4 and Figure 8. The second embodiment of the blower system 1 differs from the first embodiment of the blower system 1 in that the first ion delivery device 100 and the second ion delivery device 200 are arranged facing each other. The following will mainly describe the differences between the second embodiment and the first embodiment.

[0091] Figure 8 is a plan view showing the ventilation system 1 according to Embodiment 2. As shown in Figure 8, the ventilation system 1 is installed, for example, inside the mobile body VC shown in Figure 1. The mobile body VC includes a first seat C1, a second seat C2, a door VD (see Figure 1), and a control mechanism 10 (see Figure 1).

[0092] The first seat C1 is installed along the first direction D1. The first seat C1 includes multiple first seating areas SA1 and multiple third seating areas SA3. The multiple first seating areas SA1 are spaced apart along the first direction D1. The multiple third seating areas SA3 are spaced apart along the first direction D1. The first seating areas SA1 and the third seating areas SA3 are arranged alternately along the first direction D1. Persons can sit in the first seating areas SA1 and the third seating areas SA3.

[0093] The second seat C2 includes multiple second seating areas SA2 and multiple fourth seating areas SA4. The multiple second seating areas SA2 are spaced apart along the first direction D1. The multiple fourth seating areas SA4 are spaced apart along the first direction D1. The second seating areas SA2 and the fourth seating areas SA4 are arranged alternately along the first direction D1. Persons can sit in the second seating areas SA2 and the fourth seating areas SA4.

[0094] In the example shown in Figure 8, in a plan view, the first seating area SA1 and the second seating area SA2 face each other in the second direction D2, separated by the aisle AS. The third seating area SA3 and the fourth seating area SA4 face each other in the second direction D2, separated by the aisle AS. That is, in a plan view, the first seating area SA1 and the third seating area SA3 are located on the side of the aisle AS in the fifth direction D5. Also, in a plan view, the second seating area SA2 and the fourth seating area SA4 are located on the side of the aisle AS in the sixth direction D6.

[0095] In Embodiment 2, the first ion delivery device 100 and the second ion delivery device 200 are installed above the internal space of the mobile body VC. Specifically, the first ion delivery device 100 and the second ion delivery device 200 are installed above the first seat C1 and the second seat C2. In other words, the first ion delivery device 100 and the second ion delivery device 200 are installed above the first seating area SA1 to the fourth seating area SA4.

[0096] Furthermore, in Embodiment 2, as shown in Figure 8, in a plan view, the first ion delivery device 100 is installed on the side of the second seating area SA2 than the second ion delivery device 200. Specifically, the first ion delivery device 100 is installed above the fourth seating area SA4.

[0097] As shown in Figure 2, the first ion delivery device 100 includes a first generation unit 101, a first air blowing unit 105, a first housing 110, and a first duct 120. The first ion delivery device 100 also has a first intake port 131 and a first outlet port 132. The first generation unit 101, the first air blowing unit 105, and the first duct 120 are housed in the first housing 110.

[0098] The first generating unit 101 generates ions. The first generating unit 101 generates ions of first polarity and / or ions of second polarity. The first generating unit 101 includes a first electrode 102 and a second electrode 103. The first electrode 102 generates ions of first polarity by discharging. The second electrode 103 generates ions of second polarity by discharging.

[0099] The first duct 120 extends from the first air supply unit 105 to the first air outlet 132.

[0100] The first blower unit 105 draws in air from the first intake port 131 and blows out the drawn-in air through the first duct 120 from the first outlet port 132. The first blower unit 105 is, for example, a centrifugal fan. A centrifugal fan includes, for example, a motor and an impeller.

[0101] The first electrode 102 and the second electrode 103 protrude from within the first duct 120.

[0102] The discharge angle θ of the first ion wind F1 from the first blower unit 105 includes discharge angle θA and discharge angle θB. Discharge angle θA represents the angle with respect to the horizontal direction. Discharge angle θA is approximately 45 degrees or more and approximately 65 degrees or less downward with respect to the horizontal direction, as shown in Figure 2, for example. Typically, discharge angle θA is approximately 55 degrees. For example, discharge angle θA is the discharge angle of the first duct 120 when the first duct 120 is inclined downward with respect to the horizontal direction.

[0103] As shown in Figure 8, the discharge angle θB represents the angle with respect to the second direction D2. For example, the discharge angles θA and θB are not particularly limited and are set appropriately based on the size of the internal space of the mobile body VC, the size and arrangement of the first seat C1 and the second seat C2, and the size and arrangement of the first seating area SA1 to the fourth seating area SA4.

[0104] In other words, as shown in Figure 3, in a cross-sectional view, the first air blower 105 sends out the first ion wind F1A diagonally downward with respect to the second direction D2, thereby causing the first ion wind F1A to reach the first seating area SA1. Furthermore, as shown in Figure 8, in a plan view, the first ion wind F1 is sent out from the first air blower 105 toward the third direction D3.

[0105] As shown in Figure 8, in a plan view, the second ion delivery device 200 is installed closer to the first seating area SA1 than the first ion delivery device 100. In addition, the second ion delivery device 200 is installed above the third seating area SA3 adjacent to the first direction D1.

[0106] As shown in Figure 2, the second ion delivery device 200 includes a second generation unit 201, a second air blowing unit 205, a second housing 210, and a second duct 220. The second ion delivery device 200 also has a second intake port 231 and a second outlet port 232. The second generation unit 201, the second air blowing unit 205, and the second duct 220 are housed in the second housing 210.

[0107] The second generation unit 201 generates ions. The second generation unit 201 generates ions of first polarity and / or second polarity. The second generation unit 201 includes a third electrode 202 and a fourth electrode 203. The third electrode 202 generates ions of first polarity by discharging. The fourth electrode 203 generates ions of second polarity by discharging. Otherwise, the configuration of the second generation unit 201 is the same as that of the first generation unit 101.

[0108] The second duct 220 extends from the second air supply unit 205 to the second air outlet 232.

[0109] The second air blower 205 draws in air from the second intake port 231 and blows the drawn-in air out through the second duct 220 and out from the second outlet port 232. Otherwise, the configuration of the second air blower 205 is the same as that of the first air blower 105.

[0110] The third electrode 202 and the fourth electrode 203 protrude from within the second duct 220.

[0111] The discharge angle θ of the second ion wind F2 from the second blower unit 205 includes discharge angle θC and discharge angle θD. Discharge angle θC represents the angle with respect to the horizontal direction. As shown in Figure 2, the discharge angle θC is, for example, approximately 45 degrees or more and approximately 65 degrees or less downward with respect to the horizontal direction. Typically, the discharge angle θC is approximately 55 degrees. For example, the discharge angle θC is the discharge angle of the second duct 220 when the second duct 220 is inclined downward with respect to the horizontal direction.

[0112] As shown in Figure 8, the discharge angle θD represents the angle with respect to the second direction D2. For example, the discharge angles θC and θD are not particularly limited and are set appropriately based on the size of the internal space of the mobile body VC, the size and arrangement of the first seat C1 and the second seat C2, and the size and arrangement of the first seating area SA1 to the fourth seating area SA4.

[0113] In other words, as shown in Figure 4, in a cross-sectional view, the second air blower 205 sends out the second ion wind F2 diagonally downward with respect to the second direction D2, thereby causing the second ion wind F2 to reach the second seating region SA2. As shown in Figure 8, in a plan view, the second ion wind F2 is sent out from the second air blower 205 toward the fourth direction D4.

[0114] In Embodiment 2, in a plan view, the first ion delivery device 100 and the second ion delivery device 200 face each other. In a plan view, the first seating area SA1 from which the first ion delivery device 100 blows the first ion wind F1 and the second seating area SA2 from which the second ion delivery device 200 blows the second ion wind F2 are positioned obliquely to each other with respect to a predetermined first direction D1. Therefore, collisions between the first ion wind F1 and the second ion wind F2 can be suppressed. As a result, neutralization of ions between the first ion wind F1 and the second ion wind F2 can be suppressed.

[0115] Specifically, as shown in Figure 8, in a plan view, the third seating area SA3 and the fourth seating area SA4 face each other. The first ion delivery device 100 is installed above the fourth seating area SA4. In the fourth direction D4 of the fourth seating area SA4, above which the first ion delivery device 100 is installed, lies the second seating area SA2, from which the second ion delivery device 200 delivers the second ion wind F2.

[0116] Furthermore, the second ion delivery device 200 is installed above the third seating area SA3. In the third direction D3 of the third seating area SA3 above which the second ion delivery device 200 is installed, lies the first seating area SA1 from which the first ion delivery device 100 delivers the first ion wind F1. Therefore, collisions between the first ion wind F1 and the second ion wind F2 can be suppressed. As a result, neutralization of ions between the first ion wind F1 and the second ion wind F2 can be suppressed.

[0117] Next, with reference to Figure 8, the details of the arrangement of the first ion delivery device 100 and the second ion delivery device 200 will be described.

[0118] As shown in Figure 1, the multiple first ion delivery devices 100 are installed at intervals along the first direction D1. In the example shown in Figure 8, the multiple first ion delivery devices 100 are installed at equal intervals along the first direction D1.

[0119] Specifically, a first row L1 consisting of multiple first ion delivery devices 100 extends along a first direction D1. In the example shown in Figure 8, in a plan view, the multiple first ion delivery devices 100 in the first row L1 are arranged in a nearly straight line.

[0120] Furthermore, the multiple second ion delivery devices 200 are installed at intervals along the first direction D1. In the example shown in Figure 8, the multiple second ion delivery devices 200 are installed at equal intervals along the first direction D1.

[0121] Furthermore, a second row L2, consisting of multiple second ion delivery devices 200, extends along the first direction D1. In the example shown in Figure 8, in a plan view, the multiple second ion delivery devices 200 in the second row L2 are arranged in a nearly straight line. The first row L1 and the second row L2 face each other in the second direction D2. In a plan view, the first ion delivery device 100 and the second ion delivery device 200 that are closest to each other between the first row L1 and the second row L2 face each other in the second direction D2.

[0122] Therefore, according to Embodiment 2, ions can be effectively blown onto people riding on the mobile vehicle VC while suppressing an increase in the number of ion delivery devices (first ion delivery device 100 and second ion delivery device 200). In addition, collisions between the first ion wind F1 and the second ion wind F2 can be suppressed, thus preventing ions from being neutralized between the first ion wind F1 and the second ion wind F2.

[0123] (Variation 1) Referring to Figures 2-4, 8, and 9, the blower system 1 according to Modification 1 of Embodiment 2 will be described. The main differences between Modification 1 of Embodiment 2 and Embodiment 2 described with reference to Figure 8 are that the first ion delivery device 100 delivers the first ion wind F1 in three directions, and the second ion delivery device 200 delivers the second ion wind F2 in two directions. The differences between Modification 1 and Embodiment 2 will be mainly described below.

[0124] Figure 9 is a plan view showing the details of the arrangement of the first ion delivery device 100 and the second ion delivery device 200 according to a modified example 1 of Embodiment 2. As shown in Figure 9, the mobile unit VC is equipped with a plurality of first ion delivery devices 100 and a plurality of second ion delivery devices 200.

[0125] As shown in Figure 9, the first ion delivery device 100 delivers a first ion breeze F1 to a plurality of first seating areas SA1. The plurality of first seating areas SA1 are located on one side of the passage AS extending along the first direction D1. Therefore, one first ion delivery device 100 can deliver the first ion breeze F1 to a plurality of first seating areas SA1. As a result, even if the number of first ion delivery devices 100 is less than the number of first seating areas SA1, the ion breeze can be effectively delivered to people seated in the first seating areas SA1.

[0126] Specifically, each of the multiple first ion delivery devices 100 has multiple first outlets 132 as shown in Figure 2. For example, the first ion delivery device 100 has three first outlets 132. Two of the three first outlets 132 are located on the faces of the first ion delivery device 100 and the second ion delivery device 200. One of the three first outlets 132 is located on the face of the first ion delivery device 100 facing the wall of the mobile body VC. In other words, the first ion delivery device 100 delivers multiple first ion winds. Specifically, the first ion delivery device 100 delivers a first ion wind F1B, a first ion wind F1C, and a first ion wind F1D.

[0127] For example, as shown in Figure 3, the first air blower 105 sends out the first ion wind F1B diagonally downward with respect to the second direction D2 in a cross-sectional view, thereby causing the first ion wind F1B to reach the first seating area SA1. As shown in Figure 9, in a plan view, the first ion wind F1B is sent out from the first air blower 105 toward the third direction D3. Specifically, the first ion delivery device 100 sends out the first ion wind F1B toward the first seating area SA1 located toward the third direction D3 of the third seating area SA3.

[0128] For example, the first air blower 105 sends out the first ion wind F1C diagonally downward with respect to the second direction D2 in a cross-sectional view, thereby causing the first ion wind F1C to reach the first seating area SA1. As shown in Figure 9, in a plan view, the first ion wind F1C is sent out from the first air blower 105 toward the fourth direction D4. Specifically, the first ion delivery device 100 sends out the first ion wind F1C toward the first seating area SA1 located toward the fourth direction D4 side of the third seating area SA3.

[0129] Furthermore, for example, the first air blower 105 blows out the first ion wind F1D diagonally downward with respect to the vertical direction in a cross-sectional view, thereby transforming the first ion wind F1D into the 4 Seating area SA 4 To reach. Specifically, the first ion delivery device 100 is located on the sixth direction D6 side of the first ion delivery device 100. 4 Seating area SA 4 First ion wind F1 D Send it out.

[0130] In other words, the first ion delivery device 100 has a plurality of first seating areas SA1 and 4 Seating area SA 4 And it is possible to send out the first ion wind F1. Therefore, 4 Seating area SA 4 The second ion wind F2A is blown towards the second ion delivery device 200, and 4 Seating area SA 4 The first ion wind F1D, which is blown towards the first ion delivery device 100, merges with it. As a result, 4 Seating area SA 4 This can improve the ion concentration.

[0131] The second ion delivery device 200 is located on the side of the second ion delivery device 200 in the sixth direction D6. 4 Seating area SA 4A second ion wind F2A is sent out. The second ion wind F2A passes between the first ion wind F1B and the first ion wind F1C sent out from the first ion sending device 100. Collisions between the first ion wind F1B, the first ion wind F1C, and the second ion wind F2A can be suppressed, thus preventing ion neutralization between the first ion wind F1 and the second ion wind F2.

[0132] Furthermore, the second ion delivery device 200 delivers a second ion wind F2D to the third seating area SA3 located on the fifth direction D5 side of the second ion delivery device 200. In other words, the second ion delivery device 200 can effectively blow ions onto people seated in the second seating area SA2 and people seated in the third seating area SA3. Therefore, the difference between the concentration of the second ion wind F2 in the third seating area SA3 and the concentration of the first ion wind F1 in the first seating area SA1 can be reduced. As a result, the ion concentration in the first seat C1 can be made uniform.

[0133] (Modification 2) Referring to Figures 2-4, 8, and 10, the air blowing system 1 according to Modification 2 of Embodiment 2 will be described. The main differences between Modification 2 of Embodiment 2 and Embodiment 2 described with reference to Figure 8 are that the first ion delivery device 100 delivers the first ion wind F1 in two directions, and the second ion delivery device 200 delivers the second ion wind F2 in three directions. The differences between Modification 2 and Embodiment 2 will be mainly described below.

[0134] Figure 10 is a plan view showing the details of the arrangement of the first ion delivery device 100 and the second ion delivery device 200 according to a modified example 2 of Embodiment 2. As shown in Figure 10, the mobile unit VC is equipped with a plurality of first ion delivery devices 100 and a plurality of second ion delivery devices 200.

[0135] As shown in Figure 10, the second ion delivery device 200 delivers a second ion breeze F2 to multiple second seating areas SA2. The multiple second seating areas SA2 are located on the other side of the passage AS that extends along the first direction D1. Therefore, one second ion delivery device 200 can deliver the second ion breeze F2 to multiple second seating areas SA2. As a result, even if the number of second ion delivery devices 200 is less than the number of second seating areas SA2, the ion breeze can be effectively delivered to people seated in the second seating areas SA2.

[0136] Specifically, each of the multiple second ion delivery devices 200 has multiple second outlets 232 as shown in Figure 2. For example, the second ion delivery device 200 has three second outlets 232. Two of the three second outlets 232 are located on the faces of the second ion delivery device 200 and the first ion delivery device 100. One of the three second outlets 232 is located on the face of the second ion delivery device 200 and the wall of the mobile body VC. In other words, the second ion delivery device 200 delivers multiple second ion winds. Specifically, the second ion delivery device 200 delivers a second ion wind F2B, a second ion wind F2C, and a second ion wind F2D.

[0137] For example, as shown in Figure 4, the second air blower 205 sends out the second ion wind F2B diagonally downward with respect to the second direction D2 in a cross-sectional view, thereby causing the second ion wind F2B to reach the second seating region SA2. As shown in Figure 9, in a plan view, the second ion wind F2B is sent out from the second air blower 205 toward the third direction D3. Specifically, the second ion delivery device 200 sends out the second ion wind F2B toward the second seating region SA2 located toward the third direction D3 of the fourth seating region SA4.

[0138] For example, the second air blower 205 sends out the second ion wind F2C diagonally downward with respect to the second direction D2 in a cross-sectional view, thereby causing the second ion wind F2C to reach the second seating region SA2. As shown in Figure 9, in a plan view, the second ion wind F2C is sent out from the second air blower 205 toward the fourth direction D4. Specifically, the second ion delivery device 200 sends out the second ion wind F2C toward the second seating region SA2 located toward the fourth direction D4 of the fourth seating region SA4.

[0139] Furthermore, for example, the second air blower 205 sends out the second ion wind F2D diagonally downward with respect to the vertical in a cross-sectional view, thereby causing the second ion wind F2D to reach the first seating area SA1. Specifically, the second ion delivery device 200 sends out the second ion wind F2D to the first seating area SA1 located on the side of the second ion delivery device 200 in the fifth direction D5.

[0140] In other words, the second ion delivery device 200 can deliver the second ion wind F2 to the first seating area SA1 and multiple second seating areas SA2. Therefore, the first ion wind F1A blown from the first ion delivery device 100 toward the first seating area SA1 and the second ion wind F2D blown to the second ion delivery device 200 toward the first seating area SA1 merge. As a result, the ion concentration in the first seating area SA1 can be increased.

[0141] The first ion delivery device 100 delivers a first ion wind F1A to a first seating area SA1 located on the fifth direction D5 side of the first ion delivery device 100. The first ion wind F1A passes between the second ion wind F2B and the second ion wind F2C delivered from the second ion delivery device 200. Collisions between the second ion wind F2B, the second ion wind F2C, and the first ion wind F1A can be suppressed, thereby preventing ion neutralization between the first ion wind F1 and the second ion wind F2.

[0142] Furthermore, the first ion delivery device 100 delivers the first ion wind F1D to the fourth seating area SA4 located on the sixth direction D6 side of the first ion delivery device 100. In other words, the first ion delivery device 100 can effectively blow ions onto people seated in the first seating area SA1 and people seated in the fourth seating area SA4. Therefore, the difference between the concentration of the first ion wind F1 in the fourth seating area SA4 and the concentration of the second ion wind F2 in the second seating area SA2 can be reduced. As a result, the ion concentration in the second seat C2 can be made uniform.

[0143] [Embodiment 3] The blower system 1 according to Embodiment 3 will be described with reference to Figures 11 to 13. Embodiment 3 differs from Embodiment 1, which was described with reference to Figure 1, and Embodiment 2, which was described with reference to Figure 8, mainly in that the first ion delivery device 100 has a first output unit 141, and the second ion delivery device 200 has a second output unit 241. Hereinafter, Embodiment 3 will mainly be described in terms of the differences from Embodiment 1 and Embodiment 2.

[0144] Figure 11 is a block diagram showing the configuration of the first ion delivery device 100 of the blowing system 1 according to Embodiment 3. As shown in Figure 11, the first ion delivery device 100 includes a first generation unit 101, a first blowing unit 105, a first output unit 141, a first detection unit 142, a first control unit 150, and a first storage unit 160.

[0145] The first generating unit 101 generates ions. The first generating unit 101 generates ions of first polarity and / or ions of second polarity.

[0146] The first air blower unit 105 blows out air.

[0147] The first output unit 141 outputs sound. The sound includes, for example, a warning sound or a voice. The first output unit 141 is, for example, a speaker.

[0148] The first detection unit 142 detects a person. Specifically, the first detection unit 142 detects the approach of a person. In this case, the first detection unit 142 is, for example, a distance measuring sensor. That is, the first detection unit 142 outputs a signal to the first control unit 150 that corresponds to the distance between the person and the first detection unit 142.

[0149] Furthermore, the first detection unit 142 may detect when a person comes into contact with the first housing 110 of the first ion delivery device 100. In this case, the first detection unit 142 is, for example, a pressure sensor. The pressure sensor outputs a signal corresponding to the pressure to the first control unit 150. In other words, the first detection unit 142 outputs a signal to the first control unit 150 corresponding to the pressure generated when a person comes into contact with the first housing 110 of the first ion delivery device 100.

[0150] The first control unit 150 includes a processor such as a CPU (Central Processing Unit) or ASIC (Application Specific Integrated Circuit), and a memory device. For example, the first control unit 150 receives various signals from each element of the first ion delivery device 100 and controls each element of the first ion delivery device 100 based on the received signals. Specifically, the first control unit 150 controls each element of the first ion delivery device 100, such as the first generation unit 101, the first air blowing unit 105, the first output unit 141, the first detection unit 142, and the first storage unit 160.

[0151] The first storage unit 160 stores data and computer programs. For example, the first storage unit 160 temporarily stores data necessary for each process of the first control unit 150. The first storage unit 160 includes a storage device (main memory and auxiliary storage device), for example, a memory and a hard disk drive. The first storage unit 160 may also include removable media.

[0152] Next, with reference to Figure 11, the processing performed by the first control unit 150 will be explained. As shown in Figure 11, the first control unit 150 includes a first output control unit 151. The first control unit 150 functions as the first output control unit 151 by executing a computer program stored in the first storage unit 160.

[0153] The first output control unit 151 controls the first output unit 141. Specifically, the first output control unit 151 controls the first output unit 141 to output sound based on the detection result of the first detection unit 142. Therefore, the first ion emitter 100 can output sound to a person detected by the first detection unit 142. As a result, a sound warning can be given to the person.

[0154] More specifically, the first output control unit 151 controls the first output unit 141 to output sound when the detection result of the first detection unit 142 indicates that a person has been detected. Therefore, the first ion emitter 100 can output sound to the person detected by the first detection unit 142. As a result, a sound warning can be given to the person.

[0155] For example, if the detection result of the first detection unit 142 indicates that the distance between the first ion discharger 100 and a person is within a predetermined distance, the first output control unit 151 controls the first output unit 141 to output sound. Therefore, the first ion discharger 100 can output sound to a person approaching it. As a result, a sound warning can be given to the person.

[0156] Furthermore, for example, if the detection result of the first detection unit 142 indicates that a person has come into contact with the first ion discharger 100, the first output control unit 151 controls the first output unit 141 to output sound. Therefore, the first ion discharger 100 can output sound to a person approaching it. As a result, a sound warning can be given to the person.

[0157] Figure 12 is a block diagram showing the configuration of the second ion delivery device 200 of the blowing system 1 according to Embodiment 3. As shown in Figure 12, the second ion delivery device 200 includes a second generation unit 201, a second blowing unit 205, a second output unit 241, a second detection unit 242, a second control unit 250, and a second storage unit 260.

[0158] The configuration of the second ion delivery device 200 shown in Figure 12 is the same as the configuration of the first ion delivery device 100 in Embodiment 3, which was described with reference to Figure 11.

[0159] The second generation unit 201 generates ions. The second generation unit 201 generates ions of first polarity and / or ions of second polarity.

[0160] The second air blower unit 205 blows out air.

[0161] The second output unit 241 outputs sound. The sound includes, for example, a warning sound or a voice. The second output unit 241 is, for example, a speaker.

[0162] The second detection unit 242 detects a person. Specifically, the second detection unit 242 detects the approach of a person. In this case, the second detection unit 242 is, for example, a distance measuring sensor. That is, the second detection unit 242 outputs a signal to the second control unit 250 that corresponds to the distance between the person and the second detection unit 242.

[0163] Furthermore, the second detection unit 242 may detect when a person comes into contact with the second housing 210 of the second ion delivery device 200. In this case, the second detection unit 242 is, for example, a pressure sensor. That is, the second detection unit 242 outputs a signal to the second control unit 250 corresponding to the pressure generated when a person comes into contact with the second housing 210 of the second ion delivery device 200.

[0164] The second control unit 250 includes a processor such as a CPU or ASIC, and a memory device. For example, the second control unit 250 receives various signals from each element of the second ion delivery device 200 and controls each element of the second ion delivery device 200 based on the received signals. Specifically, the second control unit 250 controls each element of the second ion delivery device 200, such as the second generation unit 201, the second air blowing unit 205, the second output unit 241, the second detection unit 242, and the second memory unit 260.

[0165] The second storage unit 260 stores data and computer programs. For example, the second storage unit 260 temporarily stores data necessary for each process of the second control unit 250. The second storage unit 260 includes a storage device (main memory and auxiliary storage device), for example, a memory and a hard disk drive. The second storage unit 260 may also include removable media.

[0166] Next, with reference to Figure 12, the processing performed by the second control unit 250 will be explained. As shown in Figure 12, the second control unit 250 includes a second output control unit 251. The second control unit 250 functions as the second output control unit 251 by executing a computer program stored in the second storage unit 260.

[0167] The second output control unit 251 controls the second output unit 241. Specifically, the second output control unit 251 controls the second output unit 241 to output sound based on the detection result of the second detection unit 242. Therefore, the second ion emitter 200 can output sound to a person detected by the second detection unit 242. As a result, a sound warning can be given to the person.

[0168] More specifically, the second output control unit 251 controls the second output unit 241 to output sound when the detection result from the second detection unit 242 indicates that a person has been detected. Therefore, the second ion emitter 200 can output sound to the person detected by the second detection unit 242. As a result, a sound warning can be given to the person.

[0169] For example, if the detection result of the second detection unit 242 indicates that the distance between the second ion discharger 200 and a person is within a predetermined distance, the second output control unit 251 controls the second output unit 241 to output sound. Therefore, the second ion discharger 200 can output sound to a person approaching it. As a result, a sound warning can be given to the person.

[0170] Furthermore, for example, if the detection result of the second detection unit 242 indicates that a person has come into contact with the second ion discharger 200, the second output control unit 251 controls the second output unit 241 to output sound. Therefore, the second ion discharger 200 can output sound to a person approaching it. As a result, a sound warning can be given to the person.

[0171] Next, the processes performed by the first control unit 150 will be described in more detail with reference to Figures 11 to 13. Note that the processes performed by the second control unit 250 are the same as those performed by the first control unit 150 and will therefore be omitted. Figure 13 is a flowchart showing the processes performed by the first control unit 150 of the blower system 1 according to Embodiment 3. The processes performed by the first control unit 150 include steps S101 to S103.

[0172] In step S101, the first output control unit 151 determines whether the first detection unit 142 has detected a person. If the detection result of the first detection unit 142 is not a person (No in step S101), the process proceeds to step S103. If the detection result of the first detection unit 142 is a person (Yes in step S101), the process proceeds to step S102.

[0173] If the answer in step S101 is Yes, then in step S102, the first output control unit 151 controls the first output unit 141 so that it outputs sound. The process then proceeds to step S103.

[0174] In step S103, the first control unit 150 determines whether the termination condition is met. If the termination condition is not met (No in step S103), the process proceeds to step S101. If the termination condition is met (Yes in step S103), the process terminates.

[0175] Furthermore, when the second control unit 250 executes the processing shown in Figure 13, the first output unit 141 is replaced with the second output unit 241, the first detection unit 142 with the second detection unit 242, the first control unit 150 with the second control unit 250, and the first output control unit 151 with the second output control unit 251.

[0176] The first output unit 141, the first detection unit 142, the first control unit 150, and the first storage unit 160 of the first ion delivery device 100 described in Embodiment 3 may also be present in the first ion delivery device 100 of Embodiment 1. Furthermore, the second output unit 241, the second detection unit 242, the second control unit 250, and the second storage unit 260 of the second ion delivery device 200 described in Embodiment 3 may also be present in the second ion delivery device 200 of Embodiment 1.

[0177] The first output unit 141, the first detection unit 142, the first control unit 150, and the first storage unit 160 of the first ion delivery device 100 described in Embodiment 3 may also be present in the first ion delivery device 100 of Embodiment 2. Furthermore, the second output unit 241, the second detection unit 242, the second control unit 250, and the second storage unit 260 of the second ion delivery device 200 described in Embodiment 3 may also be present in the second ion delivery device 200 of Embodiment 2.

[0178] [Embodiment 4] Next, the ventilation system 1 of Embodiment 4 will be described with reference to Figures 14 to 16. The ventilation system 1 of Embodiment 4 differs from the ventilation systems 1 of Embodiments 1 to 3 in that it changes the amount of air blown. Below, the differences between Embodiment 4 and Embodiments 1 to 3 will be mainly described.

[0179] Figure 14 is a block diagram showing the configuration of the first ion delivery device 100 of the blowing system 1 of Embodiment 4. As shown in Figure 14, the first ion delivery device 100 includes a first generation unit 101, a first blowing unit 105, a third detection unit 143, a first control unit 150, and a first storage unit 160.

[0180] The first generating unit 101 generates ions. The first generating unit 101 generates ions of first polarity and / or ions of second polarity.

[0181] The first air blower unit 105 blows out air.

[0182] The third detection unit 143 detects a person. Specifically, the third detection unit 143 detects a person by detecting their body heat. The third detection unit 143 is, for example, a pyroelectric infrared sensor. A pyroelectric infrared sensor detects far-infrared rays (radiant heat) emitted from the human body.

[0183] The first control unit 150 includes a processor such as a CPU or ASIC, and a memory device. For example, the first control unit 150 receives various signals from each element of the first ion delivery device 100 and controls each element of the first ion delivery device 100 based on the received signals. Specifically, the first control unit 150 controls each element of the first ion delivery device 100, such as the first generation unit 101, the first air blowing unit 105, the third detection unit 143, and the first storage unit 160.

[0184] The first storage unit 160 stores data and computer programs. For example, the first storage unit 160 temporarily stores data necessary for each process of the first control unit 150. The first storage unit 160 includes a storage device (main memory and auxiliary storage device), for example, a memory and a hard disk drive. The first storage unit 160 may also include removable media.

[0185] Next, with reference to Figure 14, the processes performed by the first control unit 150 will be explained. As shown in Figure 14, the first control unit 150 includes a first airflow control unit 152 and a first determination unit 153. The first control unit 150 functions as the first airflow control unit 152 and the first determination unit 153 by executing a computer program stored in the first storage unit 160.

[0186] The first determination unit 153 determines whether there are many people or not based on the detection results of the third detection unit 143. Specifically, the first determination unit 153 determines whether there are many people or not based on the amount of human heat detected by the third detection unit 143 within a predetermined period. More specifically, if the amount of human heat detected by the third detection unit 143 within a predetermined period is greater than a threshold, the first determination unit 153 determines that there are many people. Conversely, if the amount of human heat detected by the third detection unit 143 within a predetermined period is not greater than a threshold, the first determination unit 153 determines that there are not many people.

[0187] The first airflow control unit 152 controls the first airflow unit 105 based on the determination result of the first determination unit 153. Therefore, the amount of airflow from the first airflow unit 105 can be changed according to the number of people. As a result, the ion concentration can be changed according to the number of people.

[0188] Specifically, if the determination result of the first determination unit 153 indicates that the amount of heat from a person detected by the third detection unit 143 within a predetermined period is not greater than a threshold, the first airflow control unit 152 controls the first airflow unit 105 to change its airflow from the current airflow set in the first airflow unit 105 to the first airflow. Furthermore, if the determination result of the first determination unit 153 indicates that the amount of heat from a person detected by the third detection unit 143 within a predetermined period is greater than a threshold, the first airflow control unit 152 controls the first airflow unit 105 to change its airflow from the current airflow set in the first airflow unit 105 to the second airflow. The second airflow is greater than the first airflow.

[0189] Figure 15 is a block diagram showing the configuration of the second ion delivery device 200 of the blowing system 1 of Embodiment 4. As shown in Figure 15, the second ion delivery device 200 includes a second generation unit 201, a second blowing unit 205, a fourth detection unit 243, a second control unit 250, and a second storage unit 260.

[0190] The configuration of the second ion delivery device 200 shown in Figure 15 is the same as the configuration of the first ion delivery device 100 in Embodiment 4, which was described with reference to Figure 14.

[0191] The second generation unit 201 generates ions. The second generation unit 201 generates ions of first polarity and / or ions of second polarity.

[0192] The second air blower unit 205 blows out air.

[0193] The fourth detection unit 243 detects a person. Specifically, the fourth detection unit 243 detects a person by detecting their body heat. The fourth detection unit 243 is, for example, a pyroelectric infrared sensor. A pyroelectric infrared sensor detects far-infrared rays (radiant heat) emitted from the human body.

[0194] The second control unit 250 includes a processor such as a CPU or ASIC, and a memory device. For example, the second control unit 250 receives various signals from each element of the second ion delivery device 200 and controls each element of the second ion delivery device 200 based on the received signals. Specifically, the second control unit 250 controls each element of the second ion delivery device 200, such as the second generation unit 201, the second air blowing unit 205, the fourth detection unit 243, and the second memory unit 260.

[0195] The second storage unit 260 stores data and computer programs. For example, the second storage unit 260 temporarily stores data necessary for each process of the second control unit 250. The second storage unit 260 includes a storage device (main memory and auxiliary storage device), for example, a memory and a hard disk drive. The second storage unit 260 may also include removable media.

[0196] Next, with reference to Figure 15, the processes performed by the second control unit 250 will be explained. As shown in Figure 15, the second control unit 250 includes a second airflow control unit 252 and a second determination unit 253. The second control unit 250 functions as the second airflow control unit 252 and the second determination unit 253 by executing a computer program stored in the second storage unit 260.

[0197] The second determination unit 253 determines whether there are many people or not based on the detection results of the fourth detection unit 243. Specifically, the second determination unit 253 determines whether there are many people or not based on the amount of human heat detected by the fourth detection unit 243 within a predetermined period. More specifically, if the amount of human heat detected by the fourth detection unit 243 within a predetermined period is greater than a threshold, the second determination unit 253 determines that there are many people. Conversely, if the amount of human heat detected by the fourth detection unit 243 within a predetermined period is not greater than a threshold, the second determination unit 253 determines that there are not many people.

[0198] The second airflow control unit 252 controls the second airflow unit 205 based on the determination result of the second determination unit 253. Therefore, the amount of air blown by the second airflow unit 205 can be changed according to the number of people. As a result, the ion concentration can be changed according to the number of people.

[0199] Specifically, if the determination result of the second determination unit 253 indicates that the amount of heat from a person detected by the fourth detection unit 243 within a predetermined period is not greater than a threshold, the second airflow control unit 252 controls the second airflow unit 205 to change its airflow from the current airflow set in the second airflow unit 205 to the first airflow. Also, if the determination result of the second determination unit 253 indicates that the amount of heat from a person detected by the fourth detection unit 243 within a predetermined period is greater than a threshold, the second airflow control unit 252 controls the second airflow unit 205 to change its airflow from the current airflow set in the second airflow unit 205 to the second airflow.

[0200] Next, the processes performed by the first control unit 150 will be described in more detail with reference to Figures 14 to 16. Note that the processes performed by the second control unit 250 are the same as those performed by the first control unit 150 and will therefore be omitted. Figure 16 is a flowchart showing the processes performed by the first control unit 150 of the first ion delivery device 100 of Embodiment 4. The processes performed by the first control unit 150 include steps S111 to S115.

[0201] In step S111, the first determination unit 153 determines whether there are many people or not based on the detection result of the third detection unit 143. If it determines that there are not many people (No in step S111), the process proceeds to step S115. If it determines that there are many people (Yes in step S111), the process proceeds to step S112.

[0202] If the answer in step S111 is Yes, then in step S112, the first airflow control unit 152 controls the first airflow unit 105 to change its airflow rate to the second airflow rate. The process then proceeds to step S113.

[0203] In step S113, the first determination unit 153 determines whether there are many people or not based on the detection result of the third detection unit 143. If it determines that there are many people (Yes in step S113), the process proceeds to step S115. If it determines that there are not many people (No in step S113), the process proceeds to step S114.

[0204] If the answer in step S113 is No, then in step S114, the first airflow control unit 152 controls the first airflow unit 105 to change its airflow rate to the first airflow rate. The process then proceeds to step S115.

[0205] If the answer is No in step S111, Yes in step S113, and after step S114, in step S115, the first control unit 150 determines whether the termination condition is met. If the termination condition is not met (No in step S115), the process returns to step S111. If the termination condition is met (Yes in step S115), the process terminates.

[0206] Furthermore, when the second control unit 250 executes the process shown in Figure 16, the first air blower unit 105 is replaced with the second air blower unit 205, the third detection unit 143 with the fourth detection unit 243, the first control unit 150 with the second control unit 250, the first air blower control unit 152 with the second air blower control unit 252, and the first determination unit 153 with the second determination unit 253.

[0207] The third detection unit 143, the first control unit 150, and the first storage unit 160 of the first ion delivery device 100 described in Embodiment 4 may be present in the first ion delivery device 100 of Embodiment 1 or the second ion delivery device 200 of Embodiment 2. Also, the fourth detection unit 243, the second control unit 250, and the second storage unit 260 of the second ion delivery device 200 described in Embodiment 4 may be present in the second ion delivery device 200 of Embodiment 1 or the first ion delivery device 100 of Embodiment 2.

[0208] (Variation 1) Referring to Figure 17, the blower system 1 according to Modification 1 of Embodiment 4 will be described. The main differences between Modification 1 of Embodiment 4 and Embodiment 4, which was described with reference to Figures 14 to 16, are that the first ion delivery device 100 controls the first blower unit 105 based on reservation information stored in the first storage unit 160, and the second ion delivery device 200 controls the second blower unit 205 based on reservation information stored in the second storage unit 260. The differences between Modification 1 and Embodiment 4 will be mainly described below.

[0209] The first storage unit 160 shown in Figure 14 stores reservation information. The reservation information stored in the first storage unit 160 includes the time to start blowing air and the amount of air blown. Specifically, the reservation information includes information that the first ion delivery device 100 will start blowing the first ion wind F1 at a predetermined time, information indicating the airflow rate of the first blowing unit 105, and information that the first ion delivery device 100 will stop blowing the first ion wind F1 at a predetermined time.

[0210] The first control unit 150 measures time. The first control unit 150 can also determine whether the time being measured has reached a predetermined time.

[0211] The first airflow control unit 152 controls the first airflow unit 105 based on the reservation information.

[0212] The second storage unit 260 shown in Figure 15 stores reservation information. The reservation information stored in the second storage unit 260 includes the time to start blowing air and the amount of air blown. Specifically, the reservation information includes information that the second ion delivery device 200 will start blowing the second ion wind F2 at a predetermined time, information indicating the airflow rate of the second blowing unit 205, and information that the second ion delivery device 200 will stop blowing the second ion wind F2 at a predetermined time.

[0213] For example, reservation information is created in advance based on the operational information of the mobile vehicle (VC). The operational information includes the names of multiple stations where the mobile vehicle (VC) stops, and the arrival times determined for each of those stations.

[0214] Note that reservation information may be created in advance, for example, based on meeting room usage reservation information. Usage reservation information includes the start time of meeting room use, the end time of meeting room use, and the number of users.

[0215] The second control unit 250 measures the time. The second control unit 250 can also determine whether the time being measured has reached a predetermined time.

[0216] The second airflow control unit 252 controls the second airflow unit 205 based on the reservation information. Therefore, the airflow system 1 can be controlled according to the requests of the person who created the reservation information. As a result, ionized air can be delivered efficiently.

[0217] Next, with reference to Figure 17, the processes performed by the first control unit 150 will be described in more detail. Note that the processes performed by the second control unit 250 are the same as those performed by the first control unit 150 and will therefore be omitted. Figure 17 is a flowchart showing the processes performed by the first control unit 150 of the first ion delivery device 100 of the modified example 1 of Embodiment 4. The processes performed by the first control unit 150 include steps S121 to S123.

[0218] In step S121, the first control unit 150 obtains reservation information from the first storage unit 160. The process then proceeds to step S122.

[0219] In step S122, the first control unit 150 determines, based on the reservation information, whether the time it measures has reached a predetermined time. If it has not reached the predetermined time (No in step S122), the process repeats step S122. If it has reached the predetermined time (Yes in step S122), the process proceeds to step S123.

[0220] If the answer in step S122 is Yes, then in step S123, the first airflow control unit 152 controls the first airflow unit 105 based on the reservation information. Specifically, the first airflow control unit 152 changes the airflow rate of the first airflow unit 105 based on the airflow rate information included in the reservation information and sends out the first ion wind F1. The process then ends.

[0221] Furthermore, when the second control unit 250 performs the processing shown in Figure 17, the first air blower unit 105 is replaced with the second air blower unit 205, the first control unit 150 with the second control unit 250, the first storage unit 160 with the second storage unit 260, and the first output control unit 151 with the second output control unit 251.

[0222] Furthermore, the first airflow control unit 152 may control the first airflow unit 105 so that it blows the first ion wind F1 from an earlier time than the predetermined time indicated by the reservation information. In addition, the second airflow control unit 252 may control the second airflow unit 205 so that it blows the second ion wind F2 from an earlier time than the predetermined time indicated by the reservation information. Therefore, the space in which the first ion delivery device 100 and the second ion delivery device 200 are installed can be filled with ions in advance. As a result, the space can be filled with ions in advance before a person enters it.

[0223] [Embodiment 5] Next, the ventilation system 1 of Embodiment 5 will be described with reference to Figures 18 and 19. The ventilation system 1 according to Embodiment 5 differs from the ventilation systems 1 of Embodiments 1 to 4 in that the first ion delivery device 100 and the second ion delivery device 200 change the amount of ion air delivered according to the opening and closing of the door of the mobile body VC. Below, Embodiment 5 will mainly be described in terms of the differences from Embodiments 1 to 4.

[0224] Figure 18 is a block diagram showing the configuration of the blower system 1 according to Embodiment 5. As shown in Figure 18, the mobile body VC includes a drive unit V1, an opening / closing sensor V2, a control unit V5, a storage unit V6, and a mobile body communication unit V7.

[0225] The drive unit V1 moves the mobile body VC.

[0226] The open / close sensor V2 detects the opening and closing of the door VD of the mobile body VC shown in Figure 1. The open / close sensor V2 may be placed on the door VD. The open / close sensor V2 outputs a signal to the control unit V5 indicating that the door VD is open. The open / close sensor V2 also outputs a signal to the control unit V5 indicating that the door VD is closed.

[0227] The control unit V5 includes a processor such as a CPU or ASIC, and a memory device. For example, the control unit V5 receives various signals from each element of the mobile body VC and controls each element of the mobile body VC based on the received signals. Specifically, the control unit V5 controls each element of the second ion delivery device 200, such as the drive unit V1, the memory unit V6, and the mobile body communication unit V7.

[0228] The storage unit V6 stores data and computer programs. For example, the storage unit V6 temporarily stores data necessary for each process of the control unit V5. The storage unit V6 includes storage devices (main memory and auxiliary storage devices), such as memory and hard disk drives. The storage unit V6 may also include removable media.

[0229] The mobile communication unit V7 communicates with the first ion discharger 100 and the second ion discharger 200. The mobile communication unit V7 is equipped with a wireless communication module conforming to a short-range wireless communication standard. The short-range wireless communication standard is, for example, Bluetooth®. For example, by associating the mobile communication unit V7 with the first ion discharger 100, the mobile unit VC and the first ion discharger 100 are linked. Also, for example, by associating the mobile communication unit V7 with the second ion discharger 200, the mobile unit VC and the second ion discharger 200 are linked. The mobile communication unit V7 may also be connected to the first ion discharger 100 and the second ion discharger 200 by wires.

[0230] The mobile communication unit V7 transmits the open / close information to the first ion discharger 100. The mobile communication unit V7 also transmits the open / close information to the second ion discharger 200.

[0231] As shown in Figure 18, the first ion delivery device 100 includes a first generation unit 101, a first air blowing unit 105, a first control unit 150, a first storage unit 160, and a first communication unit 170.

[0232] The first generating unit 101 generates ions. The first generating unit 101 generates ions of first polarity and / or ions of second polarity.

[0233] The first air blower unit 105 blows out air.

[0234] The first control unit 150 includes a processor such as a CPU or ASIC, and a memory device. For example, the first control unit 150 receives various signals from each element of the first ion delivery device 100 and controls each element of the first ion delivery device 100 based on the received signals. Specifically, the first control unit 150 controls each element of the first ion delivery device 100, such as the first generation unit 101, the first air blowing unit 105, the first storage unit 160, and the first communication unit 170.

[0235] The first storage unit 160 stores data and computer programs. For example, the first storage unit 160 temporarily stores data necessary for each process of the first control unit 150. The first storage unit 160 includes a storage device (main memory and auxiliary storage device), for example, a memory and a hard disk drive. The first storage unit 160 may also include removable media.

[0236] The first communication unit 170 communicates with the mobile communication unit V7 of the mobile unit VC. The first communication unit 170 is equipped with a wireless communication module conforming to a short-range wireless communication standard. The short-range wireless communication standard is, for example, Bluetooth®. The first communication unit 170 may also be connected to the mobile communication unit V7 by a wire.

[0237] As shown in Figure 18, the second ion delivery device 200 includes a second generation unit 201, a second air blowing unit 205, a second control unit 250, a second storage unit 260, and a second communication unit 270.

[0238] The configuration of the second ion delivery device 200 shown in Figure 18 is the same as the configuration of the first ion delivery device 100 in Embodiment 5, which was described with reference to Figure 18.

[0239] The second generation unit 201 generates ions. The second generation unit 201 generates ions of first polarity and / or ions of second polarity.

[0240] The second air blower unit 205 blows out air.

[0241] The second control unit 250 includes a processor such as a CPU or ASIC, and a memory device. For example, the second control unit 250 receives various signals from each element of the second ion delivery device 200 and controls each element of the second ion delivery device 200 based on the received signals. Specifically, the second control unit 250 controls each element of the second ion delivery device 200, such as the second generation unit 201, the second blowing unit 205, the second storage unit 260, and the second communication unit 270.

[0242] The second storage unit 260 stores data and computer programs. For example, the second storage unit 260 temporarily stores data necessary for each process of the second control unit 250. The second storage unit 260 includes a storage device (main memory and auxiliary storage device), for example, a memory and a hard disk drive. The second storage unit 260 may also include removable media.

[0243] The second communication unit 270 communicates with the mobile communication unit V7 of the mobile unit VC. The second communication unit 270 is equipped with a wireless communication module conforming to a short-range wireless communication standard. The short-range wireless communication standard is, for example, Bluetooth®. The second communication unit 270 may also be connected to the mobile communication unit V7 by a wire.

[0244] Next, with reference to Figure 18, the first control unit 150 of the first ion delivery device 100 and the second control unit 250 of the second ion delivery device 200 will be described in detail. As shown in Figure 18, the first control unit 150 includes a first airflow control unit 152. The first control unit 150 functions as the first airflow control unit 152 by executing a computer program stored in the first storage unit 160.

[0245] The first airflow control unit 152 controls the first airflow unit 105 based on the opening / closing information. Then, the second airflow control unit 252 controls the second airflow unit 205 based on the opening / closing information. Therefore, the ion concentration, which changes according to the opening and closing of the door VD, can be adjusted. As a result, it becomes easy to maintain a constant ion concentration.

[0246] Specifically, when the first communication unit 170 receives open / close information indicating that the door VD has been opened, the first airflow control unit 152 controls the first airflow unit 105 to change the airflow rate to the second airflow rate. Also, when the first communication unit 170 receives open / close information indicating that the door VD has been closed, the first control unit 150 determines whether a predetermined period has elapsed since receiving the information. If the first control unit 150 determines that a predetermined period has elapsed, the first airflow control unit 152 controls the first airflow unit 105 to change from the second airflow rate to the first airflow rate. Therefore, the first airflow unit 105 continues to send out the first ion wind F1 at the second airflow rate until the predetermined period has elapsed after the door VD has been closed. As a result, even if the ion concentration decreases when the door VD is opened for people to enter or exit, the decreased ions can be replenished because the first ion wind F1 is sent out at the second airflow rate.

[0247] Furthermore, when the second communication unit 270 receives open / close information indicating that the door VD has been opened, the second airflow control unit 252 controls the second airflow unit 205 to change the airflow rate to the second airflow rate. Also, when the second communication unit 270 receives open / close information indicating that the door VD has been closed, the second control unit 250 determines whether a predetermined period has elapsed since the information indicating that the door VD has been closed was received. If the second control unit 250 determines that a predetermined period has elapsed, the second airflow control unit 252 controls the second airflow unit 205 to change from the second airflow rate to the first airflow rate. Therefore, the second airflow unit 205 continues to send out the second ion wind F2 at the second airflow rate until the predetermined period has elapsed after the door VD has been closed. As a result, even if the ion concentration decreases when the door VD is opened for people to enter or exit, the decreased ions can be replenished because the second ion wind F2 is sent out at the second airflow rate. In addition, since the first ion wind F1 is also discharged from the first ion discharger 100, the ion concentration inside the mobile body VC is stabilized.

[0248] Next, with reference to Figure 19, the processes performed by the blower system 1 shown in Embodiment 5 will be described in detail. Figure 19 is a flowchart of the processes performed by the first ion delivery device 100 of the blower system 1 shown in Embodiment 5. As shown in Figure 19, the processes performed by the first ion delivery device 100 include steps S131 to S135. Note that the processes performed by the second control unit 250 of the second ion delivery device 200 are the same as those performed by the first control unit 150, and are therefore omitted.

[0249] In step S131, the first control unit 150 controls the first communication unit 170 so that it receives open / close information from the mobile communication unit V7. The process then proceeds to step S132.

[0250] In step S132, the first air supply control unit 152 controls the first air supply unit 105 to change the airflow to the second airflow rate based on the open / close information indicating that the door VD has been opened. The process then proceeds to step S133.

[0251] In step S133, the first control unit 150 controls the first communication unit 170 so that it receives open / close information from the mobile communication unit V7. The process then proceeds to step S134.

[0252] In step S134, the first control unit 150 determines whether a predetermined period has elapsed since it received open / close information indicating that the door VD is closed. If the predetermined period has not elapsed (No in step S134), the process repeats step S134. If the predetermined period has elapsed (Yes in step S134), the process proceeds to step S135.

[0253] If the answer in step S134 is Yes, then in step S135, the first airflow control unit 152 controls the first airflow unit 105 to change from the second airflow rate to the first airflow rate based on the open / closed information indicating that the door VD is closed. The process then ends.

[0254] Furthermore, when the second control unit 250 performs the processing shown in Figure 19, the first air blower unit 105 is replaced with the second air blower unit 205, the first control unit 150 with the second control unit 250, the first output control unit 151 with the second output control unit 251, and the first communication unit 170 with the second communication unit 270.

[0255] Embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the embodiments described above, and can be implemented in various forms without departing from its spirit. Furthermore, the multiple components disclosed in the above embodiments can be modified as appropriate. For example, some components from all the components shown in one embodiment may be added to the components of another embodiment, or some components from all the components shown in one embodiment may be deleted from the embodiment.

[0256] Furthermore, the drawings schematically show each component in order to facilitate understanding of the invention, and the thickness, length, number, spacing, etc. of each component shown may differ from the actual dimensions due to the convenience of drawing creation. Also, the configuration of each component shown in the above embodiments is merely an example and is not particularly limiting, and it goes without saying that various modifications are possible without substantially departing from the effects of the present invention.

[0257] (1) The first ion delivery device 100 shown in Figure 2 may have a first wind direction adjustment mechanism (not shown). The first wind direction adjustment mechanism adjusts the wind direction of the first ion wind F1 in a first direction D1 (Figure 1) and / or vertically. The second ion delivery device 200 shown in Figure 2 may also have a second wind direction adjustment mechanism (not shown). The second wind direction adjustment mechanism adjusts the wind direction of the second ion wind F2 in a first direction D1 (Figure 1) and / or vertically. For example, each of the first and second wind direction adjustment mechanisms includes a louver and a motor. For example, the first and second wind direction adjustment mechanisms are located at the first outlet 132 and the second outlet 232, respectively.

[0258] For example, the first wind direction adjustment mechanism may cause the wind direction of the first ion wind F1 to swing in a first direction D1 and / or vertically. For example, the second wind direction adjustment mechanism may cause the wind direction of the second ion wind F2 to swing in a first direction D1 and / or vertically. In this case, the wind direction swing pattern by the first wind direction adjustment mechanism and the wind direction swing pattern by the second wind direction adjustment mechanism may be complementary and different. For example, when the wind direction of the first ion wind F1 swings from top to bottom, the wind direction of the second ion wind F2 swings from bottom to top, and when the wind direction of the first ion wind F1 swings from bottom to top, the wind direction of the second ion wind F2 swings from top to bottom.

[0259] Furthermore, for example, the first wind direction adjustment mechanism (not shown) of the first ion delivery device 100 adjusts the wind direction of the first ion wind F1 to the third direction D3 (Figure 5) and / or the fourth direction D4 (Figure 5). Furthermore, for example, the second wind direction adjustment mechanism (not shown) of the second ion delivery device 200 adjusts the wind direction of the second ion wind F2 to the third direction D3 (Figure 5) and / or the fourth direction D4 (Figure 5).

[0260] For example, the first wind direction adjustment mechanism may cause the wind direction of the first ion wind F1 to swing in the third direction D3 and / or the fourth direction D4. For example, the second wind direction adjustment mechanism may cause the wind direction of the second ion wind F2 to swing in the third direction D3 and / or the fourth direction D4. In this case, the wind direction swing pattern by the first wind direction adjustment mechanism and the wind direction swing pattern by the second wind direction adjustment mechanism may be complementary and different. For example, when the wind direction of the first ion wind F1 swings from the third direction D3 to the fourth direction D4, the wind direction of the second ion wind F2 swings from the fourth direction D4 to the third direction D3, and when the wind direction of the first ion wind F1 swings from the third direction D3 to the fourth direction D4, the wind direction of the second ion wind F2 swings from the fourth direction D4 to the third direction D3.

[0261] (2) The air blowing system 1 shown in Figures 1 and 6 may, for example, be equipped with a motion sensor. The motion sensor detects the presence of a person. The first ion discharger 100 and the second ion discharger 200 each discharge a first ion wind F1 and a second ion wind F2 for a predetermined period of time from the moment the motion sensor detects the presence of a person.

[0262] (3) The arrangement of the first seat C1 and the second seat C2 shown in Figures 1 and 6 is not particularly limited. For example, multiple first seats C1 may be arranged along the second direction D2. For example, multiple second seats C2 may be arranged along the second direction D2.

[0263] (4) In Figures 1 and 6, the first blower unit 105 of the first ion delivery device 100 may deliver the first ion wind F1 towards the region between the first seating region SA1 and the third seating region SA3. Therefore, delivering the first ion wind F1 towards the first seating region SA1 indicates that the first ion wind F1 is delivered towards all or part of the first seating region SA1. Also, the second blower unit 205 of the second ion delivery device 200 may deliver the second ion wind F2 towards the region between the second seating region SA2 and the fourth seating region SA4. Therefore, delivering the second ion wind F2 towards the second seating region SA2 indicates that the second ion wind F2 is delivered towards all or part of the second seating region SA2.

[0264] (5) The first ion delivery device 100 may blow ion-containing air (ion wind) not only toward the first seating area SA1 but also toward the fourth seating area SA4. The fourth seating area SA4 is located below the first ion delivery device 100. The second ion delivery device 200 may blow ion-containing air (ion wind) not only toward the second seating area SA2 but also toward the third seating area SA3. The third seating area SA3 is located below the second ion delivery device 200.

[0265] (6) The installation location of the ventilation system 1 shown in Figures 1 and 6 is not limited to the mobile body VC. For example, the ventilation system 1 may be installed inside a building (e.g., indoors). [Industrial applicability]
