Description

Technical Field

[0001] The present disclosure relates to an air blowing device, an air blowing system, and an environment adjustment system.

Background Art

[0002] An air cleaning device in Patent Literature 1 includes a casing having an air inlet port and an air outlet port, and a guidance plate is provided inside the casing. The guidance plate is disposed at nearly the center of the casing, and a gap for ventilation is provided between the guidance plate and a peripheral plate of the casing. In addition, a baffle plate that covers the inner peripheral edge of the air outlet port is provided under the guidance plate. The guidance plate sends air having been sent into the casing toward the air outlet port via the gap by a fan, while guiding the same toward the peripheral plate. An opening is formed at a position corresponding to the center of the opening shape of the air outlet port, and the baffle plate straightens an airflow toward the opening.

[0003] In recent years, the functions of various devices have been expanded with addition of functions other than original functions. However, the devices are likely to be upsized due to the addition of the functions, and therefore both the expansion of the functions and suppression of upsizing have been demanded.

Further, one direction among both directions along the Y-axis will be defined as a front direction, and the other direction will be defined as a rear direction. Further, one direction among both directions along the Z-direction will be defined as an upper direction, and the other direction will be defined as a lower direction.

(Embodiment)

(1) Outline of Air Blowing Device

[0013] Figs. 1 to 11 show an air blowing device 1 according to the present embodiment. The air blowing device 1 is used in, for example, facilities such as office buildings, business offices, stores, factories, and commercial complexes. Further, the air blowing device 1 may be used in dwellings of apartment houses, independent houses, or the like.

[0014] As shown in Fig. 12, the air blowing device 1 is installed in an upper part of an air conditioning space 9. In the upper part of the air conditioning space 9, a ceiling 91 of a structure is present. From the ceiling 91, a plurality of T-bars (frameworks) 92 assembled in a lattice shape are suspended by hanging bolts 93. The plurality of T-bars 92 assembled in a lattice shape form a plurality of rectangular grids 95 arranged side by side in a lattice shape. Note that the grids 95 have a standard dimension of, for example, 600 mm × 600 mm. Further, a system ceiling is constructed with arrangement of a ceiling panel in each of the grids 95. The air blowing device 1 is suspended from the ceiling 91 by hanging tools 94 and disposed in the grids 95. The air blowing device 1 sucks air inside the air conditioning space 9, and blows out the sucked air into the air conditioning space 9 after straightening the same.

[0015] Further, as shown in Figs. 1 to 11, the air blowing device 1 includes a housing 13, a straightening plate 15, and a display surface G1. The housing 13 is formed in a box shape having an internal space 130, and includes inlet ports 13g for sending air into the internal space 130, an air blowing port 13h for blowing out the air from the internal space 130, and a squeezing part 13i for narrowing the internal space 130 toward the peripheral edge of the air blowing port 13h. The straightening plate 15 is disposed between the inlet ports 13g and the air blowing port 13h. The display surface G1 is positioned inside the internal space 130, and displays video from the air blowing port 13h toward the outside of the housing 13.

[0016] The air blowing device 1 having the configuration described above expands its functions with addition of the function of displaying video besides the function of blowing air. In addition, the display surface G1 is positioned inside the internal space 130, and displays video from the air blowing port 13h toward the outside of the housing 13 in the air blowing device 1. Thus, upsizing due to provision of the display surface G1 is suppressed. That is, the air blowing device 1 can expand functions and suppress upsizing.

(2) Details about Air Blowing Device

[0017] As shown in Figs. 2 to 5, the air blowing device 1 includes a cover 11, air blowers 12, the housing 13, a mounting bracket 14, and the straightening plate 15.

(2.1) Housing

[0018] The housing 13 includes a case 131 mainly formed of a zinc steel plate and a frame body 132.

[0019] The case 131 includes a left wall 13a, a right wall 13b, a front wall 13c, a rear wall 13d, and an upper wall 13e. Each of the left wall 13a, the right wall 13b, the front wall 13c, the rear wall 13d, and the upper wall 13e has nearly a rectangular plate shape. Further, the upper wall 13e forms an upper surface of the case 131. Each of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d extends downward from four side parts of the upper wall 13e, and forms a lateral surface of the housing 13. A lower surface of the case 131 forms a rectangular opening 13f surrounded by the respective lower ends of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d. Note that the left wall 13a and the right wall 13b are opposed to each other in a left-and-right direction along the X-axis. The front wall 13c and the rear wall 13d are opposed to each other in a fore-and-aft direction along the Y-axis. The upper wall 13e and an opening 13f are opposed to each other in a top-and-bottom direction along the Z-axis.

[0020] The frame body 132 includes a rectangle frame 132a and an edge part 132b, and is mounted on a lower surface of the case 131 by screws or the like so as to surround the opening 13f of the lower surface of the case 131.

[0021] The rectangle frame 132a is a rectangular frame formed of a flat plate. The rectangle frame 132a extends in a direction along an X-Y plane (plane defined by the X-axis and the Y-axis) so as to narrow the rectangular opening 13f formed by the respective lower ends of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d of the case 131. That is, the rectangle frame 132a functions as the squeezing part 13i for narrowing the internal space 130 toward the peripheral edge of the air blowing port 13h. Further, a rectangular opening surrounded by the rectangle frame 132a (squeezing part 13i) corresponds to the air blowing port 13h.

[0022] The edge part 132b extends obliquely downward from the outer edge of the rectangle frame 132a. The edge part 132b extends obliquely downward so as to spread from the respective lower ends of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d of the case 131.

[0023] The housing 13 including the case 131 and the frame body 132 described above has the internal space 130 surrounded by the left wall 13a, the right wall 13b, the front wall 13c, the rear wall 13d, the upper wall 13e, the rectangle frame 132a, and the air blowing port 13h. That is, the housing 13 is formed in a hollow rectangle box shape having the rectangular air blowing port 13h at its lower surface.

[0024] At the center of the upper wall 13e, the two rectangular inlet ports 13g are provided. The long sides of the inlet ports 13g are arranged along the X-axis, and the short sides thereof are arranged along the Y-axis. The two inlet ports 13g are aligned along the Y-axis. The inlet ports 13g spatially connect a space on an upper side of the upper wall 13e and the internal space 130. Further, air sent out by the air blowers 12 blows into the internal space 130 from an upper side to a lower side via the inlet ports 13g.

[0025] The air blowing port 13h is a rectangular plane arranged along the X-Y plane (plane defined by the X-axis and the Y-axis), and a normal direction of the air blowing port 13h is arranged along the Z-axis. At the peripheral edge of the air blowing port 13h, the rectangle frame 132a functioning as the squeezing part 13i is formed. The squeezing part 13i squeezes a portion on the side of the air blowing port 13h of the internal space 130 so that the internal space 130 is narrowed toward the peripheral edge of the air blowing port 13h. Alternatively, the squeezing part 13i expands the internal space 130 from the peripheral edge of the air blowing port 13h toward the outside of the air blowing port 13h. The squeezing part 13i according to the present embodiment expands in a flange shape along the X-Y plane from the respective lower ends of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d toward the air blowing port 13h.

[0026] That is, the housing 13 is formed in a box shape having the internal space 130, and has the inlet ports 13g for sending air into the internal space 130, the air blowing port 13h for blowing out the air from the internal space 130, and the squeezing part 13i for narrowing the internal space 130 toward the peripheral edge of the air blowing port 13h.

[0027] Further, the housing 13 has an expanded space 134 provided in the internal space 130. The expanded space 134 is an upper space of the internal space 130, and has a truncated quadrangular pyramid shape in its cross section when seen from a direction along the X-axis. The expanded space 134 is a space expanded from the inlet ports 13g toward the straightening plate 15 inside the internal space 130. Specifically, the front wall 13c includes an inclination wall 133c inclined rearward at its upper part, and the rear wall 13d includes an inclination wall 133d inclined frontward at its upper part. The expanded space 134 is formed by the inclination wall 133c and the inclination wall 133d.

[0028] Further, the case 131 includes a pair of mounting pieces 13k extending leftward from the left wall 13a and a pair of mounting pieces 13k extending rightward from the right wall 13b. The mounting pieces 13k are Y-shaped flat plates of which the tip end is branched into two parts.

(2.2) Air Blowers

[0029] The air blowers 12 are cross flow fans that suck air in an upper part of the housing 13 and blow out the sucked air. The air blowers 12 include cylindrical impellers 12a, and are mounted on an upper surface of the upper wall 13e of the housing 13 by screws or the like so that rotational shafts of the impellers 12a are arranged along the X-axis. The air blowers 12 are positioned on the inlet ports 13g of the upper wall 13e, and air blown out when the impellers 12a rotate flows into the internal space 130 via the inlet ports 13g.

[0030] The two air blowers 12 are aligned along the Y-axis. An air blower 12 closer to the front wall 13c will be defined as an air blower 121, and an air blower 12 closer to the rear wall 13d will be defined as an air blower 122. A direction in which the air blower 121 blows out air and a direction in which the air blower 122 blows out air are opposite to each other. The air blower 121 blows out air toward the front wall 13c (frontward) (see an arrow F1 in Fig. 5), and the air blower 122 blows out air toward the rear wall 13d (rearward) (see an arrow F2 in Fig. 5).

[0031] The air blowers 12 are driven by AC power or DC power supplied from a power system not shown, and the impellers 12a rotate when the air blowers 12 are driven.

(2.3) Cover

[0032] The cover 11 has a rectangle box shape having an opening 11a provided at its lower surface, and is mainly formed of a zinc steel plate. The cover 11 accommodates the housing 13 therein via the opening 11a, and is mounted on the housing 13 by screws or the like.

[0033] Each of a right wall and a left wall of the cover 11 has a pair of rectangular insertion holes 11b. By insertion of the mounting pieces 13k of the housing 13 into the insertion holes 11b, positioning of the housing 13 with respect to the cover 11 is performed.

[0034] Further, between a lateral surface of the cover 11 and one of the lateral surfaces of the housing 13 and between the lower surface of the cover 11 and the upper surface of the housing 13, a space serving as an air flow path 136 ranging from a lower side of the cover 11 to the air blowers 12 is formed (see Figs. 4 and 5). The flow path 136 secures the gap between the lower surface of the cover 11 and the upper surface of the housing 13 by rod-shaped spacers 11c (see Figs. 4 and 5) disposed between the lower surface of the cover 11 and the upper surface of the housing 13. A rectangle-frame-shaped inflow port 136a (see Figs. 4 and 5) of the flow path 136 is formed along the entire peripheral edge of the lower surface of the cover 11. When the air blowers 12 operate, air is sucked from the lower side of the cover 11 into the inflow port 136a along an upper surface of the edge part 132b. The air having flowed from the inflow port 136a into the flow path 136 is sucked into the air blowers 12 via the flow path 136. The air blowers 12 blow out the air having been sucked via the flow path 136 into the internal space 130 via the inlet ports 13g.

(2.4) Mounting Bracket

[0035] The mounting bracket 14 includes a mounting plate 14a and four supporting bodies 14b. The mounting plate 14a is a rectangular flat plate. The supporting bodies 14b are rod bodies, and the lower ends of the supporting bodies 14b are fixed at four corners of an upper surface of the mounting plate 14a. The upper ends of the supporting bodies 14b are fixed to a lower surface of the upper wall 13e of the housing 13. That is, the mounting plate 14a is fixed to the lower surface of the upper wall 13e by the four supporting bodies 14b, and disposed inside the internal space 130 of the housing 13. The mounting plate 14a is positioned beneath the two inlet ports 13g and opposed to the two inlet ports 13g along the Z-axis in the internal space 130.

(2.5) Straightening Plate

[0036] The straightening plate 15 has a rectangle plate shape, and includes a first surface 15a and a second surface 15b opposed to each other in its thickness direction. Further, the straightening plate 15 is mounted on a lower surface of the mounting plate 14a by screws or the like so that the first surface 15a of the straightening plate 15 contacts the lower surface of the mounting plate 14a. That is, the straightening plate 15 is disposed inside the internal space 130 so that the first surface 15a is opposed to the upper wall 13e, and so that the second surface 15b is opposed to the air blowing port 13h.

[0037] Between the peripheral edge of the straightening plate 15 and respective inner surfaces of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d of the housing 13, a gap functioning as a communication part 135 is generated. That is, the rectangle-frame-shaped communication part 135 that connects a space on the side of the first surface 15a and a space on the side of the second surface 15b in the internal space 130 is formed on the outside of the straightening plate 15. Note that the communication part 135 may be formed along the circumference of the peripheral edge of the straightening plate 15, or may be formed along only a pair of sides opposed to each other along the X-axis or the Y-axis.

[0038] The second surface 15b of the straightening plate 15 is exposed to a lower side of the housing 13 via the air blowing port 13h. That is, the second surface 15b can be seen from a lower side of the air blowing device 1 via the air blowing port 13h. Therefore, the display surface G1 is provided on the second surface 15b in the air blowing device 1. The display surface G1 functions as a display area that displays video from the air blowing port 13h toward the outside of the housing 13.

[0039] Here, the straightening plate 15 according to the present embodiment is a display device 151. The display device 151 has a rectangle plate shape. An upper surface of the display device 151 is the first surface 15a, and a lower surface thereof is the second surface 15b. On the second surface 15b of the display device 151, a light-emitting screen 151a that emits video is provided. The light-emitting screen 151a functions as the display surface G1. That is, the display device 151 serves also as the straightening plate 15, and has the functions of both the straightening plate 15 and the display surface G1.

(2.6) Air Blowing

[0040] The impellers 12a rotate when the air blowers 12 are driven, and air sent out by the air blowers 12 blows into the internal space 130 of the housing 13 from the upper side to the lower side via the inlet ports 13g. The air supplied downward from the inlet ports 13g flows toward the communication part 135 along the first surface 15a of the straightening plate 15 (display device 151), and passes through the communication part 135 from an upper side to a lower side. After that, the air advances toward the air blowing port 13h between the second surface 15b of the straightening plate 15 and the squeezing part 13i, and blows out downward from the air blowing port 13h. The air blown out from the air blowing port 13h is supplied into the air conditioning space 9 (see Fig. 12).

[0041] Here, the air blowing device 1 includes the squeezing part 13i for narrowing the internal space 130 toward the peripheral edge of the air blowing port 13h. Therefore, compared with a case where the air blowing device 1 does not include the squeezing part 13i, the air blowing device 1 has the function of enhancing the directivity of the air blown out from the air blowing port 13h. That is, the air blowing device 1 can suppress excessive diffusion of the air blown out from the air blowing port 13h, and blow out the air from the air blowing port 13h as a concentrated airflow.

[0042] Further, the air blowing device 1 has a plurality of the inlet ports 13g (two in the present embodiment), and the directions in which the air is sent from the plurality of inlet ports 13g into the internal space 130 are different from each other. Therefore, the air blowing device 1 can blow out the air downward from the air blowing port 13h as a surface airflow.

[0043] Specifically, as shown by an arrow F1 in Fig. 5, air blown out by the air blower 121 into the internal space 130 flows toward the front wall 13c along the first surface 15a of the straightening plate 15, passes through the communication part 135 from the upper side to the lower side, and flows toward the rear wall 13d along the second surface 15b of the straightening plate 15. Further, as shown by an arrow F2 in Fig. 5, air blown out by the air blower 122 into the internal space 130 flows toward the rear wall 13d along the first surface 15a of the straightening plate 15, passes through the communication part 135 from the upper side to the lower side, and flows toward the front wall 13c along the second surface 15b of the straightening plate 15. The air flowing from the air blower 121 along the arrow F 1 and the air flowing from the air blower 122 along the arrow F2 collide with each other under the second surface 15b of the straightening plate 15 (near the center in the fore-and-aft direction of the second surface 15b), and blow out downward from the air blowing port 13h. At this time, the air flowing along the arrow F 1 and the air flowing along the arrow F2 advance in directions (opposite directions) in which the air flowing along the arrow F 1 and the air flowing along the arrow F2 approach each other, and collide under the second surface 15b of the straightening plate 15. As a result, the air blowing out downward from the air blowing port 13h turns into a surface airflow, and can blow out in a wide range under the air blowing device 1 with a more uniform airflow amount.

[0044] Further, the internal space 130 has the expanded space 134 (see Fig. 5) expanded from the inlet ports 13g toward the straightening plate 15. Therefore, generation of a dead zone where air hardly flows can be suppressed in the internal space 130.

[0045] Specifically, the air supplied from the inlet ports 13g toward the internal space 130 from the upper side to the lower side turns into not only an airflow that flows immediately below the inlet ports 13g and collides with the first surface 15a of the straightening plate 15 but also an airflow that flows from the inlet ports 13g to the lower side while gradually spreading along the expanded space 134 and collides with the first surface 15a of the straightening plate 15. Since the expanded space 134 is gradually expanded toward the lower side, generation of a dead zone where almost no air flows hardly occurs in an upper part of the internal space 130. That is, the expanded space 134 has a shape obtained by cutting off upper corners of the internal space 130, and generation of a dead zone hardly occurs in the internal space 130. Accordingly, the air blowing device 1 can reduce pressure loss of the air in the internal space 130 to increase air blowing efficiency.

[0046] Further, an amount of the air blown out from the air blowing port 13h preferably fluctuates with 1/f fluctuation. Specifically, the air blowers 12 cause the amount of the air blown into the internal space 130 via the inlet ports 13g to fluctuate with 1/f fluctuation by changing the rotation speed of the impellers 12a. As a result, the air blowing device 1 can cause the amount of the air blown out from the air blowing port 13h to fluctuate with 1/f fluctuation. Then, a person inside the air conditioning space 9 (see Fig. 12) can feel natural wind from an airflow fluctuating with 1/f fluctuation and relax.

(2.7) Display

[0047] The air blowing device 1 includes the display device 151 as the straightening plate 15. The display device 151 is a liquid crystal display device, an organic EL display device, or the like. Further, the display device 151 has the light-emitting screen 151a that emits video, and the light-emitting screen 151a functions as the display surface G1. A person inside the air conditioning space 9 can see video displayed on the light-emitting screen 151a via the air blowing port 13h.

[0048] The display device 151 is driven by AC power or DC power supplied from the power system not shown. Then, the display device 151 receives video data through wired communication or wireless communication, and displays video based on the video data on the light-emitting screen 151a. The wireless communication is, for example, preferably wireless communication complying with a standard such as Wi-Fi (TM), Bluetooth (TM), ZigBee (TM), and low power radio (specified low power radio) that does not require a license. Alternatively, the display device 151 may be configured to enable attachment/detachment of a portable external storage device such as a USB flash drive and an SD memory card, and may reproduce video data stored in the portable external storage device and display video on the light-emitting screen 151a.

[0049] The video displayed on the light-emitting screen 151a of the display device 151 functioning as the display surface G1 is preferably video that makes a person relax. The video that makes a person relax is, for example, background video reflecting nature such as mountains, forests, woods, skies, stars, moons, evening, sunlight, bonfire, and seas. Further, the video that makes a person relax may be healing video that changes its color, shape, or the like. A person inside the air conditioning space 9 (see Fig. 12) can relax by seeing the display surface G1.

[0050] Further, the air blowing device 1 can further increase a relaxation effect on a person inside the air conditioning space 9 (see Fig. 12) by causing the amount of the air blown out from the air blowing port 13h to fluctuate with 1/f fluctuation while displaying the video that makes the person relax on the display surface G1.

[0051] As described in (2.6) and (2.7), the air blowing device 1 has the function of blowing out air into the air conditioning space 9 and the function of displaying video on to the air conditioning space 9. Therefore, the air blowing device 1 motivates a person having seen video to move to a place under the air blowing device 1 by displaying video on the display surface G1. The person having moved to the place under the air blowing device 1 has a relaxed feeling through an airflow blown out from the air blowing device 1, particularly an airflow fluctuating with 1/f fluctuation and background video displayed on the display surface G1.

(2.8) Standard Dimension

[0052] The air blowing device 1 is disposed in the rectangular grids 95 formed by the plurality of T-bars 92 assembled in a lattice shape shown in Fig. 12. Therefore, the dimension of the outer periphery of the frame body 132 of the housing 13 is preferably a dimension corresponding to the standard dimension of the grids 95.

[0053] The grids 95 have a standard dimension of, for example, 600 mm × 600 mm. In this case, the frame body 132 is preferably a square frame body, and formed to have a size slightly smaller than the outer dimension 600 mm × 600 mm. Accordingly, when the air blowing device 1 is fitted into the grids 95, design characteristics of a system ceiling can be improved with a reduction in a sense of incongruity on the frame body 132 accommodated in the grids 95.

(2.9) Selection of Air Blowing Device

[0054] Further, in a case where a plurality of the air blowing devices 1 are provided, the air blowing devices 1 preferably perform the following operation.

[0055] An operator selects any one of the air blowing devices 1 by operating a terminal device 8, and the terminal device 8 transmits a device selection signal containing identification information (device identification information) on the selected air blowing device 1. In each of the air blowing devices 1, the display device 151 blinks video displayed on the light-emitting screen 151a (display surface G1) if the device identification information contained in the device selection signal received by a communication unit 16 matches device identification information on the own device.

[0056] Accordingly, the air blowing device 1 can inform the existence of the own device to the operator. As a result, the operator can easily find the air blowing device 1 that he/she looks for among the air blowing devices 1.

(3) First Modified Example

[0057] A blowing device 1A according to a first modified example further includes a discharging device 2 as shown in Fig. 13.

[0058] The discharging device 2 is disposed in a flow path 136. In Fig. 13, the discharging device 2 is disposed between a lateral surface of a cover 11 and a lateral surface of a housing 13 in the flow path 136. Further, the discharging device 2 adds an effective component to air flowing toward air blowers 12 in the flow path 136. The air blowers 12 suck the air containing the effective component via the flow path 136, and blow out the air containing the effective component into an internal space 130. As a result, the air containing the effective component is straightened by a straightening plate 15, and then blows out downward from an air blowing port 13h to be supplied into an air conditioning space 9 (see Fig. 12).

[0059] Specifically, the discharging device 2 has a pair of electrodes, and one of the pair of electrodes is caused to retain water. Then, the discharging device 2 generates discharge between the pair of electrodes by applying a voltage between the pair of electrodes to generate radical as an effective component and electrostatically atomize the water retained by the electrode. Therefore, the discharging device 2 generates charged particle water of a nanometer size in which the radical is contained in fine liquid droplets of the electrostatically-atomized water. The radical serves as a base that produces useful effects in various scenes, other than serving to perform disinfection, deodorizing, moisturizing, freshness keeping, and inactivation of viruses.

[0060] Further, the discharging device 2 may generate discharge between the pair of electrodes without causing the electrode to retain water. In this case, the discharging device 2 generates atmospheric ion as the effective component by the discharge generated between the pair of electrodes.

[0061] Note that the discharging device 2 may be configured to be provided opposed to an inner surface of at least one of a left wall 13a, a right wall 13b, a front wall 13c, and a rear wall 13d. For example, the discharging device 2 may be configured to be provided opposed to the respective inner surfaces of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d, or may be configured to be provided opposed to the respective inner surfaces of the front wall 13c and the rear wall 13 d.

(4) Second Modified Example

[0062] Fig. 14 shows the block configuration of an air blowing device 1B according to a second modified example. The air blowing device 1B is one obtained by further providing a communication unit 16 and a control unit 17 in the air blowing device 1 according to the embodiment. Note that the block configuration shown in Fig. 14 is a diagram for particularly describing an operation of the air blowing device 1B, and does not show all the constituting elements of the air blowing device 1B.

[0063] The air blowing device 1B further includes the communication unit 16 and the control unit 17 in addition to two air blowers 12 and a display device 151. The control unit 17 has an air blowing control unit 17a and a video switching unit 17b.

[0064] The communication unit 16 has at least an interface function for wireless communication to receive a wireless signal. The wireless communication is, for example, preferably wireless communication complying with a standard such as Wi-Fi, Bluetooth, ZigBee, and low power radio (specified low power radio) that does not require a license. Note that the communication unit 16 may perform not only reception of a wireless signal but also transmission of a wireless signal.

[0065] The control unit 17 preferably includes a computer system. That is, in the control unit 17, a part or all of the functions of the control unit 17 is realized when a processor such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit) reads and runs a program stored in a memory. The control unit 17 includes the processor that operates according to the program as a primary hardware configuration. The type of the processor is not limited so long as the processor is capable of realizing the functions by running the program. The processor is composed of one or a plurality of electronic circuits including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). The circuit illustrated here is an IC and an LSI but varies depending on an integration degree. A circuit called a system LSI, a VLSI (Very Large Scale Integration), or a ULSI (Ultra Large Scale Integration) may be used. A field-programmable gate array (FPGA) programmed after manufacturing of an LSI or a reconfigurable logic device enabling reconfiguration of a connection relationship inside an LSI or setup of circuit partition inside the LSI can also be used for the same purpose. The plurality of electronic circuits may be integrated on one chip, or may be provided on a plurality of chips. The plurality of chips may be disposed in a consolidated manner or a dispersed manner.

[0066] The air blowing control unit 17a controls an amount of air blown out from each of the two air blowers 12 by separately controlling respective operations of the two air blowers 12.

[0067] The video switching unit 17b switches video displayed on a light-emitting screen 151a (display surface G1) of the display device 151 to any of a plurality of video. For example, the display device 151 accesses an external video database, and selects and displays one video from among a multiplicity of video stored in the video database on the light-emitting screen 151a. Upon this, the video switching unit 17b provides an instruction to display video to the display device 151. The display device 151 displays the instructed video on the light-emitting screen 151a.

[0068] Further, the control unit 17 controls the two air blowers 12 and the display device 151 on the basis of a control signal received by the communication unit 16.

[0069] Specifically, an operator who manages the air blowing device 1B carries a terminal device 8. The terminal device 8 is, for example, a tablet terminal, a smart phone, or a dedicated terminal. The operator transmits various control signals to the communication unit 16 of the air blowing device 1B by operating the terminal device 8. Examples of the various control signals include an air blowing control signal, a video control signal, and an air blowing mode control signal, or the like. As an example, the terminal device 8 displays a Web browser screen or an application screen, and the operator causes the various control signals to be transmitted from the terminal device 8 by operating the browser screen or the application screen.

[0070] The air blowing control signal is a control signal for controlling an amount of air to be blown by the air blowing device 1B. Then, when the communication unit 16 of the air blowing device 1B receives the air blowing control signal, the air blowing control unit 17a adjusts the amount of the air blown out from each of the two air blowers 12 by separately controlling the respective operations of the two air blowers 12 on the basis of the air blowing control signal.

[0071] The air blowing mode control signal is a control signal for controlling an air blowing mode of the air blowers 12. The two air blowers 12 included in the air blowing device 1B can operate in any of a plurality of preset air blowing modes. In the present embodiment, a first air blowing mode, a second air blowing mode, and a third air blowing mode are used as the plurality of air blowing modes. The first air blowing mode is an air blowing mode in which the two air blowers 12 separately operate. The second air blowing mode is an air blowing mode in which the two air blowers 12 operate in synchronization with each other. The third air blowing mode is an air blowing mode in which at least one of the two air blowers 12 sucks air inside an internal space 130 from inlet ports 13g. In this case, the air blowing control unit 17a selects any one of the plurality of air blowing modes on the basis of an air blowing mode instruction signal, and causes the two air blowers 12 to operate in the selected air blowing mode.

[0072] The first air blowing mode is an air blowing mode in which the two air blowers 12 separately operate. When the two air blowers 12 operate in the first air blowing mode, an operator can separately adjust an amount of air blown out from each of the two air blowers 12 by operating the terminal device 8.

[0073] The second air blowing mode is an air blowing mode in which the two air blowers 12 operate in synchronization with each other. When the two air blowers 12 operate in the second air blowing mode, amounts of air blown out from the two air blowers 12 are adjusted in synchronization with each other with a preset pattern. For example, when the air blowers 121 and 122 fluctuate the airflow amount periodically, the respective operations of the air blowers 121 and 122 are synchronized with each other so that the timing when an airflow amount of the air blower 121 becomes maximum matches the timing when an airflow amount of the air blower 122 becomes minimum, and so that the timing when the airflow amount of the air blower 121 becomes minimum matches the timing when the airflow amount of the air blower 122 becomes maximum. Alternatively, the respective operations of the air blowers 121 and 122 are synchronized with each other so that the timing when the airflow amount of the air blower 121 becomes maximum matches the timing when the airflow amount of the air blower 122 becomes maximum, and so that the timing when the airflow amount of the air blower 121 becomes minimum matches the timing when the airflow amount of the air blower 122 becomes minimum.

[0074] The third air blowing mode is an air blowing mode in which at least one of the two air blowers 12 sucks air inside the internal space 130 from the inlet ports 13g. The air blowers 12 can suck the air inside the internal space 130 from the inlet ports 13g by reversing a rotational direction of impellers 12a. Therefore, in the third air blowing mode, the respective impellers 12a of the air blowers 121 and 122 reversely rotate, and the air blowers 121 and 122 suck the air from the internal space 130. Note that one of the air blowers 121 and 122 may cause the impeller 12a to normally rotate to blow out air into the internal space 130, and the other thereof may cause the impeller 12a to reversely rotate to suck air from the internal space 130.

[0075] The video control signal is a control signal for instructing video to be displayed on the light-emitting screen 151a by the display device 151. For example, the video control signal instructs any one of a multiplicity of video data stored in a video database as video to be displayed. Then, when the communication unit 16 of the air blowing device 1B receives the video control signal, the video switching unit 17b instructs the display device 151 to display the video based on the video control signal. The display device 151 downloads the instructed video from the video database, and displays the downloaded video on the light-emitting screen 151a.

[0076] Accordingly, the air blowing device 1B can perform, by further including the communication unit 16, the air blowing control unit 17a, and the video switching unit 17b, an air flowing operation and a display operation according to manipulation of the external terminal device 8.

[0077] Further, the air blowing device 1B can flexibly change a pattern of an air blowing operation by operating in any of the plurality of air blowing modes.

(5) Third Modified Example

[0078] Fig. 15 shows the block configuration of an air blowing device 1C according to a third modified example. The air blowing device 1C is one obtained by further providing an opening/closing member 3 and an opening/closing control unit 17c in the air blowing device 1B according to the second modified example. Note that the block configuration shown in Fig. 15 is a diagram for particularly describing an operation of the air blowing device 1C, and does not show all the constituting elements of the air blowing device 1C.

[0079] The opening/closing member 3 is a so-called flap having a flat plate shape, and driven to be opened/closed by a motor not shown or driving means such as a cylinder. As shown in Figs. 16 and 17, the opening/closing member 3 is mounted on each of the inner surfaces of a left wall 13a, a right wall 13b, a front wall 13c, and a rear wall 13d of a housing 13, and configured to rotate (change) between an opening state in which a communication part 135 is opened and a closing state in which the communication part 135 is closed. The communication part 135 corresponds to the gap between the peripheral edge of a straightening plate 15 and the inner surface of the housing 13. Note that Figs. 16 and 17 show the opening/closing member 3 mounted on the front wall 13c and the rear wall 13d.

[0080] A control unit 17 of the air blowing device 1C further includes the opening/closing control unit 17c. The opening/closing control unit 17c controls an opening/closing operation of the opening/closing member 3 by controlling the driving means for the opening/closing member 3. The opening/closing control unit 17c controls a direction of air blown out from an air blowing port 13h by controlling the opening/closing operation of the opening/closing member 3.

[0081] For example, as shown in Fig. 16, the opening/closing control unit 17c puts the opening/closing member 3 mounted on each of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d into the opening state. In this case, air blown out from the air blowing port 13h turns into a surface airflow (downflow surface airflow) blowing out immediately below the air blowing port 13h (see arrows F1 and F2 in Fig. 16).

[0082] Further, as shown in Fig. 17, the opening/closing control unit 17c puts the opening/closing member 3 mounted on the front wall 13c into the opening state, and puts the opening/closing member 3 mounted on the left wall 13a, the right wall 13b, and the rear wall 13d into the closing state. In this case, air flows to the communication part 135 arranged along the front wall 13c, while air does not flow to the communication part 135 arranged along each of the left wall 13a, the right wall 13b, and the rear wall 13d. Accordingly, the air blown out from the air blowing port 13h blows out from the front side to the rear side of the air blowing port 13h (see an arrow F3 in Fig. 17).

[0083] As described above, the air blowing device 1C can control the direction of the air blown out from the air blowing port 13h with the opening/closing member 3.

(6) Fourth Modified Example

[0084] Fig. 18 shows the block configuration of an air blowing device 1D according to a fourth modified example. The air blowing device 1D is one obtained by further providing a straightening plate driving unit 41, an opening/closing member 42, and an up-and-down control unit 17d in the air blowing device 1B according to the second modified example. Note that the block configuration shown in Fig. 18 is a diagram for particularly describing an operation of the air blowing device 1D, and does not show all the constituting elements of the air blowing device 1D.

[0085] The straightening plate driving unit 41 moves a straightening plate 15 up and down along a Z-axis by a motor or driving means such a cylinder (see Figs. 19 and 20). That is, the straightening plate driving unit 41 moves the straightening plate 15 along a direction in which inlet ports 13g and an air blowing port 13h are opposed to each other.

[0086] The opening/closing member 42 is a so-called flap having a flat plate shape, and driven to be opened/closed by a motor not shown or driving means such as a cylinder. As shown in Figs. 19 and 20, the opening/closing member 42 is a rectangle frame 132a configured to be rotatable with respect to an edge part 132b of a frame body 132. Further, the opening/closing member 42 (rectangle frame 132a) functions as a squeezing part 13i when closed and aligned along a horizontal direction (direction along an X-Y plane). When the opening/closing member 42 rotates downward and is opened, the peripheral edge of an opening 13f of a case 131 serves as the peripheral edge of the air blowing port 13h. That is, the opening/closing member 42 is mounted on each of four sides of the edge part 132b of the frame body 132, and configured to rotate (change) between an opening state in which the peripheral edge of the opening 13f is opened and a closing state in which the opening/closing member 42 functions as the squeezing part 13i with the peripheral edge of the opening 13f closed. Note that Figs. 19 and 20 show the opening/closing member 42 mounted on a front side and a rear side of the rectangle-frame-shaped edge part 132b.

[0087] A control unit 17 of the air blowing device 1D further includes the up-and-down control unit 17d. The up-and-down control unit 17d controls an up-and-down operation of the straightening plate driving unit 41 and an opening/closing operation of the opening/closing member 42 by controlling driving means. The up-and-down control unit 17d performs wind area control of air blown out from the air blowing port 13h by controlling the up-and-down operation of the straightening plate driving unit 41 and the opening/closing operation of the opening/closing member 3.

[0088] For example, in Fig. 19, the up-and-down control unit 17d has moved the straightening plate 15 to an upper limit position, and has put the opening/closing member 42 into the closing state. In this case, the straightening plate 15 is positioned inside an internal space 130, and the opening/closing member 42 functions as the squeezing part 13i. Therefore, the air blowing device 1D can suppress excessive diffusion of air blown out from the air blowing port 13h. That is, the air blowing device 1D can blow out the air from the air blowing port 13h as a concentrated airflow.

[0089] Further, in Fig. 20, the up-and-down control unit 17d has moved the straightening plate 15 to a lower limit position, and has put the opening/closing member 42 into the opening state. In this case, the straightening plate 15 moves down to a lower side of the air blowing port 13h and is positioned outside the internal space 130, and the opening/closing member 42 opens the peripheral edge of the opening 13f. Therefore, the air blowing device 1D diffuses air blown out from the air blowing port 13h. That is, the air blowing device 1D can blow out the air from the air blowing port 13h as a diffused airflow.

(7) Fifth Modified Example

[0090] Figs. 21 to 29 show an air blowing device 1E according to a fifth modified example.

[0091] As shown in Figs. 21 to 23, the air blowing device 1E includes a projection plate 152 as a straightening plate 15 instead of a display device 151. The projection plate 152 has a rectangle plate shape. An upper surface of the projection plate 152 is a first surface 15a, and a lower surface thereof is a second surface 15b. On the lower surface of the projection plate 152, a projection surface 152a is provided. The projection surface 152a is a surface onto which video is irradiated via an air blowing port 13h, and functions as a display surface G1. On the projection surface 152a, a screen texture that reflects projected video is, for example, preferably pasted.

[0092] Fig. 30 shows an air blowing system VS1 including the air blowing device 1E. The air blowing system VS1 includes a projector device 7 in addition to the air blowing device 1E. The projector device 7 is disposed on a floor of an air conditioning space 9 or a table or the like. The projector device 7 irradiates video toward the projection surface 152a (display surface G1) of the air blowing device 1E provided in an upper part of the air conditioning space 9.

[0093] A person inside the air conditioning space 9 can see the video having been irradiated onto the projection surface 152a via the air blowing port 13h.

[0094] The projector device 7 accesses an external database, selects one video from among a multiplicity of video stored in the video database, and irradiates the selected video onto the projection surface 152a. An operator preferably transmits a video control signal to the projector device 7 by operating a terminal device 8. Upon receiving the video control signal, the projector device 7 downloads instructed video from the video database, and irradiates the downloaded video onto the projection surface 152a.

[0095] The air blowing device 1E having the configuration described above includes the projection plate 152 instead of the display device 151. Therefore, the air blowing device 1E can suppress its dimension (height dimension) along a Z-axis. That is, the air blowing device 1E has the function of displaying video in addition to the function of blowing air, but can further suppress upsizing.

(8) Sixth Modified Example

[0096] An air blowing device 1F in Figs. 31 and 32 is one obtained by further providing light sources 5 in the air blowing device 1E according to the fifth modified example.

[0097] The light sources 5 are disposed over a projection plate 152A so as to be opposed to a first surface 15a of a projection plate 152A (straightening plate 15) inside an internal space 130. The light sources 5 are, for example, long rod-shaped bar lamps, and include solid-state light-emitting elements such as a plurality of LEDs (Light Emitting Diodes), organic ELs (Organic Electro Luminescence, OEL), and laser diodes. In the air blowing device 1F, a longitudinal direction of each of the three light sources 5 is aligned along a Y-axis, and the three light sources 5 are arranged along an X-axis. The light sources 5 are lighted up by AC power or DC power supplied from a power system not shown, and emit illumination light downward.

[0098] In the air blowing device 1F, an upper surface of the projection plate 152A is the first surface 15a, and a lower surface thereof is a second surface 15b. The projection plate 152A emits light incident on the first surface 15a from the second surface 15b. Further, the projection plate 152A reflects light incident on the second surface 15b. That is, the projection plate 152A functions as a translucent plate for light incident on the first surface 15a, and functions as a reflection plate for light incident on the first surface 15a. Accordingly, illumination light emitted by the light sources 5 passes through the projection plate 152A, is emitted from the projection surface 152a (display surface G1), and irradiated downward from an air blowing port 13h. In addition, the projection plate 152A further has a function as a diffusion plate. Therefore, illumination light emitted from the projection surface 152a (display surface G1) turns into diffused light, and a relaxation effect by the illumination light can be increased. That is, the air blowing device 1F further includes the light sources 5 that are disposed inside the internal space 130 and emit illumination light, and the illumination light is emitted from the display surface G1 toward the air blowing port 13h. The illumination light is emitted from the display surface G1 toward the air blowing port 13h, and the illumination light emitted from the display surface G1 turns into diffused light.

[0099] Further, the projection plate 152A functions as a reflection plate for light incident on the first surface 15a. Therefore, the first surface 15a serves as the projection surface 152a (display surface G1).

[0100] Fig. 33 shows the block configuration of the air blowing device 1F. A control unit 17 of the air blowing device 1F includes an air blowing control unit 17a, a lighting control unit 17e, and an operation mode switching unit 17f. Note that the block configuration shown in Fig. 33 is a diagram for particularly describing an operation of the air blowing device 1F, and does not show all the constituting elements of the air blowing device 1F.

[0101] The lighting control unit 17e performs respective control of lighting and extinction of the light sources 5 by providing an instruction of a lighting state to the light sources 5. That is, the light sources 5 are lighted up or extinguished by the lighting control unit 17e. Further, the light sources 5 are dimming-controlled by the lighting control unit 17e when the light sources 5 are light sources that enable dimming. Further, the light sources 5 are toning-controlled by the lighting control unit 17e when the light sources 5 are light sources that enable toning.

[0102] The operation mode switching unit 17f selects any of a plurality of operation modes including a video mode in which video is displayed on the display surface G1 and an illumination mode in which illumination light is emitted from the display surface G1 according to an operation mode signal.

[0103] An operator selects a desired operation mode from among the plurality of operation modes by operating a terminal device 8, and the terminal device 8 transmits an operation mode signal instructing the selected operation mode to the air blowing device 1F. Then, when a communication unit 16 of the air blowing device 1F receives the operation mode signal, the operation mode switching unit 17f switches an operation mode of the air blowing device 1F to the operation mode instructed by the operation mode signal.

[0104] Specifically, the lighting control unit 17e performs extinction control of the light sources 5 when instructed to enter the video mode. Meanwhile, a projector device 7 irradiates video onto the projection surface 152a (display surface G1) when receiving the operation mode signal and instructed to enter the video mode. That is, in the video mode, the light sources 5 are extinguished, and video is displayed on the projection surface 152a.

[0105] Further, the lighting control unit 17e performs lighting control of the light sources 5 when instructed to enter the illumination mode. Meanwhile, the projector device 7 also stops projection of video on the projection surface 152a (display surface G1) when receiving the operation mode signal and instructed to enter the illumination mode. That is, in the illumination mode, the light sources 5 are lighted up, and video is not displayed on the projection surface 152a.

[0106] Note that the operation modes are not limited to the video mode and the illumination mode described above. The operation modes may be modes other than the video mode and the illumination mode, and the number of the operation modes that can be instructed may be three or more.

[0107] Further, the lighting control unit 17e may perform control of the light sources 5 according to an airflow generated by the air blowing device 1F.

[0108] For example, the light sources 5 are dimmed or toned according to an amount of air blown out from the air blowing device 1F. Specifically, an output of the illumination light of the light sources 5 is increased as the air blowing device 1F blows out a large amount of air. Further, the illumination light of the light sources 5 is more approximated to red as the air blowing device 1F blows out a large amount of air, and is approximated to blue as the air blowing device 1F blows out a small amount of air.

[0109] Further, in a case where the discharging device 2 operates and air blown out from the air blowing device 1A contains an effective component in (3) the first modified example described above, illumination light of the light sources 5 is dimmed, and blue illumination light is, for example, irradiated inside an air conditioning space 9.

(9) Seventh Modified Example

[0110] Video displayed on the display surface G1 may be video other than background video and healing video.

[0111] For example, the video displayed on the display surface G1 is video that informs a state of a person positioned under the air blowing device 1 through a message, a symbol, a color, or the like. In this case, a management system including the air blowing device 1 acquires identification information (person identification information) on the person positioned under the air blowing device 1, and displays the video that informs the state of the person corresponding to the acquired person identification information on the display surface G1. The management system performs authentication processing for a person inside the air conditioning space 9 and state determination processing for the person inside the air conditioning space 9 on the basis of schedule information, a captured image by a camera inside the air conditioning space 9, information from an information terminal carried by the person, or the like, and manages a state of the person in association with person identification information.

[0112] The state of the person includes, for example, a state in which the person is on the phone, a state in which the person is in a remote conference, a state in which the person is on a break, a state in which the person is at work, or the like. In this case, the person inside the air conditioning space 9 can easily understand a state of a surrounding person inside the air conditioning space 9, and take an action (such as speaking, being quiet, and moving) according to the state of the surrounding person.

[0113] Further, the video displayed on the display surface G1 may be a message for a person inside the air conditioning space 9. For example, video such as a message for issuing a welcome, a message for informing an emergency, a message for informing a business contact, and a message for informing news is, for example, displayed on the display surface G1.

(10) Eighth Modified Example

[0114] The respective control described above such as airflow control, video switching, wind direction control, wind area control, air blowing mode switching, operation mode switching, and lighting control may be any of manual control using a smart phone, a tablet terminal, and an operation device provided on a wall surface in the air conditioning space 9 and automatic control using various sensors provided in the air conditioning space 9. The sensors include a human body detection sensor (such as an infrared sensor, a camera image sensor, and a thermal image sensor), a temperature sensor, a humidity sensor, an air quality sensor, a carbon dioxide sensor, or the like. In addition, the respective control described above may be cooperative control according to states of other equipment (such as air conditioning equipment and illumination equipment).

[0115] Further, the straightening plate 15 may be configured to be movable along the X-Y plane. In this case, the straightening plate 15 is moved along the X-Y plane inside the internal space 130 by a driving mechanism having an electric actuator or the like, and can vary its slide position that is a position on the X-Y plane. Further, the directivity of air blown out from the air blowing port 13h of the air blowing device 1, 1A to 1F can be controlled with a change in the slide position of the straightening plate 15.

[0116] Further, the squeezing part 13i may only be configured to squeeze the portion on the side of the air blowing port 13h of the internal space 130 so that the internal space 130 is narrowed toward the peripheral edge of the air blowing port 13h. For example, the squeezing part 13i may have such a shape as to gradually expand the internal space 130 upward from the peripheral edge of the air blowing port 13h.

[0117] Further, the straightening plate 15 is a single plate member, but may use a plurality of plate members.

[0118] Further, a structure on which the air blowing device 1, 1A to 1F is mounted is not limited to the ceiling 91, but may be mounted on another structure such as a base provided in the upper part of the air conditioning space 9.

[0119] Further, the configurations of the embodiment and the respective modified examples described above can be appropriately combined together, and the effects of the respective configurations can be similarly obtained.

(11) Environment Adjustment System

[0120] Fig. 34 is a block diagram showing an environment adjustment system ES1. The environment adjustment system ES1 includes an air blowing device 1G and a control system CS1. The environment adjustment system ES1 preferably further includes an imaging device C1. Note that the air blowing device 1G is one in which the functions of any one or at least two of the air blowing devices 1 and 1A to 1F described above are combined together.

[0121] The air blowing device 1G is provided in the upper part of the air conditioning space 9. Then, the air blowing device 1G blows out air from the air blowing port 13h to an air blowing area R1 under the air blowing device 1G to generate an airflow in the air blowing area R1. Further, the air blowing device 1G can let a user H1 present in the air blowing area R1 and a person H2 present in the air conditioning space 9 see video by displaying the video on the display surface G1.

[0122] The imaging device C1 captures an image of at least a part of the air conditioning space 9 including the air blowing area R1, and outputs the captured image to the control system CS1. The captured image is preferably a color or monochrome moving image but may be a still image.

[0123] Upon receiving the captured image from the imaging device C1, the control system CS1 performs air blowing control and video control on the basis of the captured image. Under the air blowing control, the air blowing device 1G is controlled to control air blown out from the air blowing port 13h toward the air blowing area R1. Under the video control, the air blowing device 1G or a projector device 7 (see Fig. 30) is controlled to control video displayed on the display surface G1.

[0124] Specifically, the control system CS1 estimates actions and states of the user H1 present in the air blowing area R1 and the person H2 present in the air conditioning space 9 on the basis of the captured image. Using a learning model constructed by machine learning such as deep learning, the control system CS1 estimates the actions and the states of the user H1 and the person H2 reflected in the captured image. The learning model is preferably constructed by deep learning using FCN (Fully Convolutional Networks), CNN (Convolutional Neural Network), or the like. The machine learning uses the captured image for learning and the actions and the states of the user H1 and the person H2 reflected in the captured image for learning as teacher data. Further, the learning model may use another algorithm such as support vector machine. In analyzing the captured image of the imaging device C1, software including a prescribed image processing algorithm is used as such image processing software. However, the software is not limited to one installed in the imaging device C1 or an interface near the imaging device C1, but may be an external one connected to the control system CS1 that relies on so-called AI (Artificial Intelligence) for an image processing analysis technology.

[0125] Then, the control system CS1 performs the air blowing control and the video control on the basis of an estimation result of the action and the state of at least one of the user H1 and the person H2.

[0126] That is, the environment adjustment system ES1 further includes the imaging device C1 that captures an image of the user H1 present in the air blowing area R1. The control system CS1 switches video displayed on the display surface G1 according to an analysis result of an action and a state of the user H1 from the image captured by the imaging device C1. Further, the control system CS1 controls air blown out from the air blowing port 13h toward the air blowing area R1 according to an analysis result of the action and the state of the user H1 from the image captured by the imaging device C1.

[0127] Hereinafter, the air conditioning control and the video control of the control system CS1 in the air conditioning space 9 will be described using Fig. 35, assuming that the air conditioning space 9 is a free address working space of an office. In this case, the air blowing area R1 is a space in which a user works or has a break or the like, and office fixtures such as a desk and a chair are installed in the air blowing area R1.

[0128] The control system CS1 operates in any of respective control modes of stages ST1 to ST6 in Fig. 35. The following (11. 1) Selection Stage ST1 and (11.2) Preparation Stage ST2 enable, for example, a user to select any vacant seat and do work in a seated state on an office floor. The following (11.3) Concentration Stage ST3, (11.4) Chat Stage ST4, and (11.5) Creation Stage ST5 aim to enhance productivity efficiency of business, while providing a relaxable scene. In addition, the following (11.6) Cleaning Stage ST6 aims to take measures against, for example, infectious diseases.

(11.1) Selection Stage ST1

[0129] The control system CS1 displays, when the air blowing area R1 is put into a specific state, video that informs recommendation of use of the air blowing area R1 on the display surface G1 as the video control.

[0130] Specifically, when cleaning of the air blowing area R1 is completed in the cleaning stage ST6 that will be described later (corresponding to the specific state of the air blowing area R1), the control system CS1 switches a control mode to the selection stage ST1. After setting the control mode to the selection stage ST1, the control system CS1 displays that a user is permitted to use the air blowing area R1 on the display surface G1. The video displayed on the display surface G1 in the selection stage ST1 is, for example, video of a message such as "available" or video of a color (for example, blue) by which the user is enabled to intuitively recognize availability of the air blowing area R1.

[0131] In the present modified example, the user H1 sits on a chair in the air blowing area R1 of the air blowing device 1G that displays on the display surface G1 that the user H1 is permitted to use the air blowing area R1. After sitting on the chair in the air blowing area R1, the user H1 starts doing work. Accordingly, the user H1 can easily recognize an available space, and feels a sense of ease.

[0132] Over the user H1 sitting on the chair in the air blowing area R1, the air blowing device 1G is provided. Then, the user H1 can adjust an intensity, a direction, or the like of air blown out by the air blowing device 1G by running an application installed in advance in a tablet terminal, a smart phone, or a laptop personal computer carried by the user H1. Further, the user H1 can switch the video displayed on the display surface G1 of the air blowing device 1G to favorite one by running the application. Further, the user H1 can also set a content of a message displayed on the display surface G1 of the air blowing device 1G.

(11.2) Preparation Stage ST2

[0133] The control system CS1 that operates in the selection stage ST1 switches a control mode from the selection stage ST1 to the preparation stage ST2 when the user H1 stays in the air blowing area R1 for a time threshold or more. The control system CS1 that operates in the preparation stage ST2 starts an air blowing operation to blow out air from the air blowing port 13h of the air blowing device 1G as the air blowing control when the user H1 stays in the air blowing area R1 for a time threshold or more.

[0134] In the present modified example, the imaging device C1 captures an image of at least a part of the air conditioning space 9 including the air blowing area R1. Upon receiving the captured image from the imaging device C1, the control system CS1 counts an elapsed time since the time when the user H1 has sit on the chair in the air blowing area R1 on the basis of the captured image. When the elapsed time reaches the time threshold, the control system CS1 performs the air blowing control of the air blowing device 1G to cause air to be blown out from the air blowing port 13h of the air blowing device 1G.

[0135] In the preparation stage ST2, the environment adjustment system ES1 supports the user H1 who is about to start doing work in the air blowing area R1 to concentrate by generating an airflow in the air blowing area R1.

[0136] Further, the control system CS1 may perform the air blowing control of the air blowing device 1G to start the air blowing operation of the air blowing device 1G when detecting that the user H1 sitting on the chair in the air blowing area R1 has taken a preset specific action (for example, raising one hand) on the basis of the captured image.

[0137] Further, the control system CS1 may count the time when the user H1 stays in the air blowing area R1 using another human detection means such as pyroelectric sensor that detects a user inside the air blowing area R1.

(11.3) Concentration Stage ST3

[0138] The control system CS1 that operates in the preparation stage ST2 detects a state of the user H1 on the basis of a captured image. Then, the control system CS1 switches a control mode from the preparation stage ST2 to the concentration stage ST3 when the user H1 is in a specific state. The control system CS1 that operates in the concentration stage ST3 displays video that informs refusal of communication with the user H1 on the display surface G1 as the video control.

[0139] In order to reduce the risk of recent infectious diseases, person-to-person conferences are desired to be avoided as much as possible, and therefore so-called web conferences have been frequently adopted in general. When a person is in a Web conference while sitting on a chair, it is often difficult for surrounding persons to recognize whether the person concerned is in the Web conference or does not mind being spoken to by the surrounding persons. Therefore, the surrounding persons speak to the person concerned in many cases, and the person concerned in the Web conference is annoyed. In order to prevent this trouble, it is considered that an intention to refuse communication is displayed on a screen of a ceiling. Thus, the concentration stage ST3 prevents a person from being spoken to by surrounding persons in a Web conference to enhance productivity efficiency of business.

[0140] For example, the control system CS1 displays, when the user H1 is in a conference, video that informs refusal of communication with the user H1 on the display surface G1 as the video control. At this time, a message such as "The user H1 is in a remote conference. Please do not speak to the user H1." is displayed on the display surface G1.

[0141] Moreover, the control system CS1 may further include the function of managing access to the air conditioning space 9. In this case, the control system CS1 stores in advance information on persons permitted to access the air conditioning space 9, and can read address information on an information terminal such as a tablet terminal and a smart phone carried by a person when identifying the person accessing the air conditioning space 9. Then, upon detecting the person H2 approaching the user H1 on the basis of a captured image, the control system CS1 transmits a message such as "The user H1 is in a remote conference. Please do not speak to the user H1" on an information terminal carried by the person H2.

[0142] Accordingly, the user H1 can concentrate without being interrupted by surrounding persons.

(11.4) Chat Stage ST4

[0143] The control system CS1 that operates in the concentration stage ST3 detects a state of the user H1 on the basis of a captured image. Then, the control system CS1 switches a control mode from the concentration stage ST3 to the chat stage ST4 when the user H1 is not in a specific state. The control system CS1 that operates in the chat stage ST4 displays video to inform that communication with the user H1 is possible on the display surface G1 as the video control.

[0144] For example, the control system CS1 displays, when the user H1 is not in a conference, video to inform that communication with the user H1 is possible on the display surface G1 as the video control. At this time, a message such as "Welcome" is displayed on the display surface G1.

[0145] Moreover, the control system CS1 may further include the function of managing access to the air conditioning space 9. In this case, the control system CS1 stores in advance information on persons permitted to access the air conditioning space 9, and can read address information on an information terminal such as a tablet terminal and a smart phone carried by a person when identifying the person accessing the air conditioning space 9. Then, upon detecting the person H2 approaching the user H1 on the basis of a captured image, the control system CS1 transmits a message such as "Communication with the user H1 is possible." on an information terminal carried by the person H2.

[0146] Accordingly, the person H2 around the user H1 can communicate with the user H1 without interrupting the user H1.

(11.5) Creation Stage ST5

[0147] The control system CS1 that operates in the concentration stage ST3 or the chat stage ST4 detects a state of the user H1 on the basis of a captured image. Then, the control system CS1 switches a control mode from the concentration stage ST3 or the chat stage ST4 to the creation stage ST5 when the user H1 takes a specific action. The control system CS1 that operates in the creation stage ST5 displays video having the function of making the user H1 relax on the display surface G1 as the video control.

[0148] For example, the user H1 occasionally loses a posture, and is lost in thought while looking up at a ceiling. Then, when the user H1 continues to look up at the ceiling for a prescribed time or more, the control system CS1 displays video having the function of making the user H1 relax on the display surface G1. The video that makes the user H1 relax is, for example, background video reflecting nature such as mountains, forests, woods, skies, stars, moons, evening, sunlight, bonfire, and seas. Further, the video that makes the user H1 relax may be healing video that changes its color, shape, or the like. The user H1 can relax and refresh by seeing the display surface G1.

[0149] Further, the control system CS1 that operates in the creation stage ST5 preferably causes an amount of air blown out from the air blowing port 13h of the air blowing device 1G to fluctuate with 1/f fluctuation. The user H1 can feel natural wind from an airflow fluctuating with 1/f fluctuation, and relax and refresh.

(11.6) Cleaning Stage ST6

[0150] The control system CS1 that operates in the concentration stage ST3, the chat stage ST4, or the creation stage ST5 detects a state or an action of the user H1 on the basis of a captured image. Then, when the user H1 is away from the air blowing area R1, the control system CS1 switches a control mode from the concentration stage ST3, the chat stage ST4, or the creation stage ST5 to the cleaning stage ST6. The control system CS1 that operates in the cleaning stage ST6 cleans the air blowing area R1 by causing air to be blown out from the air blowing port 13h of the air blowing device 1G toward the air blowing area R1 as the air blowing control.

[0151] The control system CS1 blows away dust, trash, or the like attached to a desk and a chair by applying air from the air blowing device 1G to the desk and the chair inside the air blowing area R1. Accordingly, when the user H1 is away from the air blowing area R1, the control system CS1 can keep the air blowing area R1 clean by cleaning the air blowing area R1 with an airflow.

[0152] Further, the air blowing device 1G preferably includes the discharging device 2 (see Fig. 13) according to the first modified example described above. In this case, with the discharging device 2, the air blowing device 1G can generate an effective component such as radical, charged particle water of a nanometer size in which the radical is contained, and air ion, and add the generated effective component to air blown out to the air blowing area R1. As a result, it is possible to perform disinfection of a desk and a chair inside the air blowing area R1.

[0153] Further, the control system CS1 that operates in the cleaning stage ST6 displays that the air blowing area R1 is being cleaned on the display surface G1. The video displayed on the display surface G1 in the cleaning stage ST6 is, for example, video of a color by which a user is enabled to intuitively recognize unavailability of the air blowing area R1. In this case, the control system CS1 preferably makes the color of the video complementary or opposite to a surrounding color of the display surface G1 as the video control when cleaning the air blowing area R1. As a result, the video displayed on the display surface G1 can be made conspicuous. Therefore, the user H1 can easily recognize a space that is being cleaned, and feels a sense of ease.

[0154] Further, the control system CS1 that operates in the cleaning stage ST6 may display a message such as "cleaning" on the display surface G1.

(11.7) Flow of Respective Stages

[0155] Basically, the control mode of the control system CS1 transitions in the order of the selection stage ST1, the preparation stage ST2, the concentration stage ST3, the chat stage ST4, the creation stage ST5, and the cleaning stage ST6 to complete its one cycle. However, the control mode may transition to any of the concentration stage ST3, the chat stage ST4, and the creation stage ST5 after the preparation stage ST2. Further, the number of respective execution times of the concentration stage ST3, the chat stage ST4, and the creation stage ST5 in one cycle is not limited to a specific number of times.

[0156] That is, the control mode may only transition to the selection stage ST1 after the cleaning stage ST6, and the order of the concentration stage ST3, the chat stage ST4, and the creation stage ST5 and the number of respective execution times of the concentration stage ST3, the chat stage ST4, and the creation stage ST5 are not limited to specific modes.

(11.8) Gestures

[0157] The control system CS1 may determine at least one of the starts and ends of the respective stages described above on the basis of gestures (actions) made by the user H1.

[0158] Specifically, the control system CS1 determines gestures made by the user H1 on the basis of an image captured by the imaging device C1. The gestures made by the user H1 are determined in advance so as to correspond to the starts and ends of the stages. The plurality of gestures are actions distinguishable from each other. For example, a gesture corresponding to the start of the preparation stage ST2 is an action of "raising one hand." A gesture corresponding to the start of the creation stage ST5 is an action of "crossing both hands behind a head." A gesture corresponding to the start of the cleaning stage ST6 is an action of "waving one hand."
