[0009] The present disclosure generally relates to a blower, a blower system, and an environmental conditioning system. More particularly, the present disclosure relates to a blower, a blower system, and an environmental conditioning system that include a straightening vane.

[0010] The embodiment described below is merely an example of an embodiment of the present disclosure. The present disclosure is not limited to the following embodiment, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0011] In the following description, unless otherwise specified, the X-axis, Y-axis, and Z-axis are defined as being orthogonal to each other in FIG. 1. For convenience, one of the two directions along the X-axis will be referred to as the rightward direction, and the other as the leftward direction. Furthermore, one of the two directions along the Y-axis will be referred to as the forward direction, and the other as the backward direction. Furthermore, one of the two directions along the Z-axis will be referred to as the upward direction, and the other as the downward direction.

[0012] (Embodiment) (1) Overview of the blower 1 to 11 show a blower 1 according to this embodiment. The blower 1 is used in facilities such as office buildings, offices, stores, factories, and commercial facilities. The blower 1 may also be used in apartment buildings, detached houses, and the like.

[0013] As shown in FIG. 12 , the air blower 1 is attached above the air-conditioned space 9. Above the air-conditioned space 9 is a ceiling 91 of the building. A plurality of T-bars (framework) 92 arranged in a lattice pattern are suspended from the ceiling 91 by suspension bolts 93. The plurality of T-bars 92 arranged in a lattice pattern form a plurality of rectangular grids 95 arranged in a lattice pattern. The standard dimensions of the grids 95 are, for example, 600 mm × 600 mm. A system ceiling is constructed by placing ceiling panels or the like on each of the grids 95. The air blower 1 is suspended from the ceiling 91 by suspension devices 94 and placed on the grid 95. The air blower 1 draws in air from the air-conditioned space 9, rectifies the air, and blows it out into the air-conditioned space 9.

[0014] As shown in FIGS. 1 to 11 , the air blower 1 includes a housing 13, a rectifying vane 15, and a display surface G1. The housing 13 is formed in a box shape with an internal space 130, and includes an air intake 13g for feeding air into the internal space 130, an air outlet 13h for expelling air from the internal space 130, and a restrictor 13i that narrows the internal space 130 toward the periphery of the air outlet 13h. The rectifying vane 15 is disposed between the air intake 13g and the air outlet 13h. The display surface G1 is located in the internal space 130 and displays an image from the air outlet 13h toward the outside of the housing 13.

[0015] The blower device 1 having the above-described configuration has an expanded function by having a display function for displaying images in addition to the blowing function. Furthermore, in the blower device 1, the display surface G1 is located in the internal space 130 and displays images from the air outlet 13h toward the outside of the housing 13, thereby preventing the device from becoming larger due to the provision of the display surface G1. In other words, the blower device 1 can expand its functions while preventing it from becoming larger.

[0016] (2) Details of the blower As shown in FIGS. 2 to 5, the blower 1 includes a cover 11, a blower 12, a housing 13, a mounting bracket 14, and a rectifying plate 15.

[0017] (2.1) Housing The housing 13 includes a case 131 formed mainly from a zinc steel plate, and a frame 132 .

[0018] The case 131 includes a left wall 13a, a right wall 13b, a front wall 13c, a rear wall 13d, and a top wall 13e. The left wall 13a, the right wall 13b, the front wall 13c, the rear wall 13d, and the top wall 13e are each shaped like a substantially rectangular plate. The top wall 13e forms the top surface of the case 131. The left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d extend downward from four sides of the top wall 13e, forming side surfaces of the housing 13. The bottom surface of the case 131 forms a rectangular opening 13f surrounded by the lower ends of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d. The left wall 13a and the right wall 13b face each other in the left-right direction along the X-axis. The front wall 13c and the rear wall 13d face each other in the front-rear direction along the Y-axis. The upper wall 13e and the opening 13f face each other in the vertical direction along the Z axis.

[0019] The frame 132 includes a rectangular frame 132a and an edge 132b, and is attached to the bottom surface of the case 131 with screws or the like so as to surround the opening 13f on the bottom surface of the case 131.

[0020] The rectangular frame 132a is a rectangular frame formed of a flat plate. The rectangular frame 132a extends in a direction along the XY plane (a plane defined by the X and Y axes) so as to narrow a rectangular opening 13f formed by the lower ends of the left wall 13a, right wall 13b, front wall 13c, and rear wall 13d of the case 131. That is, the rectangular frame 132a forms a narrowing portion 13i that narrows the internal space 130 toward the periphery of the air outlet 13h. The rectangular opening surrounded by the rectangular frame 132a (narrowing portion 13i) corresponds to the air outlet 13h.

[0021] The edge 132b extends obliquely downward from the outer edge of the rectangular frame 132a. The edge 132b extends obliquely downward so as to widen from the lower ends of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d of the case 131.

[0022] The housing 13, which includes the case 131 and the frame body 132, has an internal space 130 surrounded by a left wall 13a, a right wall 13b, a front wall 13c, a rear wall 13d, an upper wall 13e, a rectangular frame 132a, and an air outlet 13h. That is, the housing 13 is formed in the shape of a hollow rectangular box having a rectangular air outlet 13h on its bottom surface.

[0023] Two rectangular air intakes 13g are provided in the center of the upper wall 13e. The long sides of the air intakes 13g are aligned along the X-axis, and the short sides of the air intakes 13g are aligned along the Y-axis. The two air intakes 13g are aligned along the Y-axis. The air intakes 13g spatially connect the space above the upper wall 13e to the internal space 130. Air sent out by the blower 12 passes through the air intakes 13g and is blown from top to bottom into the internal space 130.

[0024] The air outlet 13h is a rectangular plane along the XY plane (a plane defined by the X and Y axes), and the normal direction of this air outlet 13h is along the Z axis. A rectangular frame 132a constituting the throttling portion 13i is formed on the periphery of the air outlet 13h. The throttling portion 13i chokes the portion of the internal space 130 on the air outlet 13h side so as to narrow the internal space 130 toward the periphery of the air outlet 13h. Alternatively, the throttling portion 13i expands the internal space 130 from the periphery of the air outlet 13h to the outside of the air outlet 13h. In this embodiment, the throttling portion 13i extends in a brim-like shape along the XY plane from the lower ends of the left wall 13a, right wall 13b, front wall 13c, and rear wall 13d toward the air outlet 13h.

[0025] That is, the housing 13 is formed in a box shape having an internal space 130, and has an air intake 13g for sending air into the internal space 130, an air outlet 13h for expelling air from the internal space 130, and a constriction portion 13i that narrows the internal space 130 toward the periphery of the air outlet 13h.

[0026] The housing 13 also has an expansion space 134 in the internal space 130. The expansion space 134 is an upper space of the internal space 130, and its cross section viewed from the direction along the X-axis has a quadrangular pyramid shape. The expansion space 134 is a space that expands as it approaches the air rectifying vane 15 in the internal space 130 from the intake port 13g. Specifically, the front wall 13c has an inclined wall 133c that is inclined backward at an upper portion of the front wall 13c, and the rear wall 13d has an inclined wall 133d that is inclined forward at an upper portion of the rear wall 13d. The expansion space 134 is formed by the inclined wall 133c and the inclined wall 133d.

[0027] The case 131 also has 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 flat, Y-shaped pieces with two branches at the tip.

[0028] (2.2) Blower Blower 12 is a crossflow fan that draws in and expels air above housing 13. Blower 12 has a cylindrical impeller 12a and is attached to the upper surface of upper wall 13e of housing 13 with screws or the like so that the rotation axis of impeller 12a is aligned with the X-axis. Blower 12 is located above air intake port 13g in upper wall 13e, and the air expelled by the rotation of impeller 12a flows into internal space 130 through air intake port 13g.

[0029] The two fans 12 are arranged side by side along the Y axis, with the fan 12 closer to the front wall 13c being fan 121 and the fan 12 closer to the rear wall 13d being fan 122. The direction in which fan 121 blows out air is opposite to the direction in which fan 122 blows out air. Fan 121 blows out air toward the front wall 13c (forward) (see arrow F1 in FIG. 5), and fan 122 blows out air toward the rear wall 13d (rearward) (see arrow F2 in FIG. 5).

[0030] The blower 12 is driven by AC power or DC power supplied from a power system (not shown), and when the blower 12 is driven, the impeller 12a rotates.

[0031] (2.3) Cover The cover 11 is a rectangular box with an opening 11a on the bottom surface and is made mainly of zinc steel sheet. The cover 11 accommodates the housing 13 inside the cover 11 through the opening 11a and is attached to the housing 13 with screws or the like.

[0032] A pair of rectangular insertion holes 11b are formed in each of the right and left walls of the cover 11. The housing 13 is positioned relative to the cover 11 by inserting the mounting pieces 13k of the housing 13 into the insertion holes 11b.

[0033] Furthermore, spaces are formed between the side surfaces of the cover 11 and the side surfaces of the housing 13, and between the lower surface of the cover 11 and the upper surface of the housing 13, forming air flow paths 136 for air flowing from below the cover 11 to the fan 12 (see FIGS. 4 and 5). The flow path 136 ensures a gap between the lower surface of the cover 11 and the upper surface of the housing 13 by means of a rod-shaped spacer 11c (see FIGS. 4 and 5) disposed between the lower surface of the cover 11 and the upper surface of the housing 13. A rectangular frame-shaped inlet 136a (see FIGS. 4 and 5) of the flow path 136 is formed along the entire periphery of the lower surface of the cover 11. When the fan 12 operates, air is drawn into the inlet 136a from below the cover 11 along the upper surface of the edge 132b. The air flowing into the flow path 136 from the inlet 136a passes through the flow path 136 and is drawn into the fan 12. The blower 12 draws in air through the flow path 136 and discharges it into the internal space 130 through the air intake port 13g.

[0034] (2.4) Mounting bracket The mounting bracket 14 includes a mounting plate 14a and four supports 14b. The mounting plate 14a is a rectangular flat plate. The supports 14b are rods, and the lower ends of the supports 14b are fixed to the four corners of the upper surface of the mounting plate 14a. The upper ends of the supports 14b are fixed to the lower surface of the upper wall 13e of the housing 13. In other words, the mounting plate 14a is fixed to the lower surface of the upper wall 13e by the four supports 14b and is disposed in the internal space 130 of the housing 13. The mounting plate 14a is located below the two air intake ports 13g in the internal space 130 and faces the two air intake ports 13g along the Z axis.

[0035] (2.5) Current plate The rectifying plate 15 has a rectangular plate shape and includes a first surface 15a and a second surface 15b that face each other in the thickness direction. The rectifying plate 15 is attached to the lower surface of the mounting plate 14a with screws or the like so that the first surface 15a of the rectifying plate 15 contacts the lower surface of the mounting plate 14a. That is, the rectifying plate 15 is disposed in the internal space 130 so that the first surface 15a faces the upper wall 13e and the second surface 15b faces the air outlet 13h.

[0036] Gaps constituting communication portions 135 are formed between the periphery of the rectifying plate 15 and the inner surfaces of the left wall 13a, right wall 13b, front wall 13c, and rear wall 13d of the housing 13. That is, a rectangular frame-shaped communication portion 135 is formed on the outside of the rectifying plate 15, connecting the space on the first surface 15a side with the space on the second surface 15b side in the internal space 130. Note that the communication portion 135 may be formed along the entire periphery of the rectifying plate 15, or may be formed along only a pair of sides facing each other along the X-axis or Y-axis.

[0037] Second surface 15b of rectifying plate 15 is exposed below housing 13 through air outlet 13h. That is, second surface 15b can be seen from below blower device 1 through air outlet 13h. Therefore, blower device 1 is provided with display surface G1 on second surface 15b. Display surface G1 forms a display area that displays an image from air outlet 13h toward the outside of housing 13.

[0038] Here, the rectifying plate 15 of this embodiment is a display device 151. The display device 151 has a rectangular plate shape, with the upper surface of the display device 151 being a first surface 15a and the lower surface of the display device 151 being a second surface 15b. The second surface 15b of the display device 151 is provided with a light-emitting screen 151a that emits an image, and the light-emitting screen 151a constitutes the display surface G1. In other words, the display device 151 also serves as the rectifying plate 15 and has the functions of both the rectifying plate 15 and the display surface G1.

[0039] (2.6) Ventilation When blower 12 is driven, impeller 12a rotates, and the air sent out by blower 12 passes through intake port 13g and is blown from top to bottom into internal space 130 of housing 13. The air supplied downward from intake port 13g flows along first surface 15a of rectifying vane 15 (display device 151) toward communication section 135, passes through communication section 135 from top to bottom, then travels between second surface 15b of rectifying vane 15 and throttle section 13i toward air outlet 13h, and is blown downward from air outlet 13h. The air blown out from air outlet 13h is supplied to air-conditioned space 9 (see FIG. 12).

[0040] Here, by including the restricting portion 13i that narrows the internal space 130 toward the periphery of the air outlet 13h, the air blower 1 has the function of increasing the directionality of the air blown out from the air outlet 13h compared to a case where the restricting portion 13i is not included. In other words, the air blower 1 can prevent the air blown out from the air outlet 13h from being excessively diffused, and can make the air blown out from the air outlet 13h into a concentrated airflow.

[0041] In addition, the blower device 1 has multiple air intake ports 13g (two in this embodiment), and the directions in which air is sent from the multiple air intake ports 13g into the internal space 130 are different from each other, so that the air blown downward from the air outlet 13h can be made into a surface airflow.

[0042] Specifically, as indicated by arrow F1 in Fig. 5, air discharged by blower 121 into internal space 130 flows along first surface 15a of current rectifier 15 toward front wall 13c, passes through communication portion 135 from top to bottom, and then flows along second surface 15b of current rectifier 15 toward rear wall 13d. Also, as indicated by arrow F2 in Fig. 5, air discharged by blower 122 into internal space 130 flows along first surface 15a of current rectifier 15 toward rear wall 13d, passes through communication portion 135 from top to bottom, and then flows along second surface 15b of current rectifier 15 toward front wall 13c. The air flowing from blower 121 along arrow F1 and the air flowing from blower 122 along arrow F2 collide below second surface 15b of current rectifier 15 (near the center of second surface 15b in the front-to-rear direction) and are blown downward from air outlet 13h. At this time, the air flowing along arrow F1 and the air flowing along arrow F2 move toward each other (in opposite directions) and collide below second surface 15b of straightening plate 15. As a result, the air blown downward from air outlet 13h becomes a planar airflow, and air can be blown out at a more uniform volume over a wide area below blower 1.

[0043] Furthermore, the internal space 130 has an expansion space 134 (see FIG. 5) that expands from the air intake port 13g toward the rectifying plate 15, thereby preventing the internal space 130 from having a dead zone where almost no air flows.

[0044] Specifically, air supplied from the air intake port 13g from top to bottom into the internal space 130 flows not only directly downward from the air intake port 13g and collides with the first surface 15a of the air straightening vane 15, but also flows downward from the air intake port 13g while gradually expanding along the expansion space 134 and collides with the first surface 15a of the air straightening vane 15. Because the expansion space 134 gradually expands downward, a dead zone where almost no air flows is unlikely to occur in the upper part of the internal space 130. In other words, the expansion space 134 has a shape in which the upper corners of the internal space 130 are cut off, and a dead zone is unlikely to occur in the internal space 130. Therefore, the blower device 1 can reduce air pressure loss in the internal space 130 and improve air blowing efficiency.

[0045] Furthermore, it is preferable that the amount of air discharged from air outlet 13h fluctuates with 1 / f fluctuation. Specifically, blower 12 fluctuates the amount of air discharged into interior space 130 through air inlet 13g with 1 / f fluctuation by fluctuating the rotation speed of impeller 12a. As a result, blower device 1 can fluctuate the amount of air discharged from air outlet 13h with 1 / f fluctuation. Then, people in air-conditioned space 9 (see FIG. 12) can feel the natural breeze due to the airflow fluctuating with 1 / f fluctuation, and can relax.

[0046] (2.7)Display The air blower 1 is provided with a display device 151 as the rectifying plate 15. The display device 151 is a liquid crystal display device, an organic EL display device, or the like. The display device 151 has a light-emitting screen 151a that emits an image, and the light-emitting screen 151a constitutes the display surface G1. A person in the air-conditioned space 9 can view the image displayed on the light-emitting screen 151a through the air outlet 13h.

[0047] Display device 151 is driven by AC power or DC power supplied from a power system (not shown). Display device 151 receives video data via wired or wireless communication and displays an image based on the video data on light-emitting screen 151a. The wireless communication is preferably wireless communication that complies with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power radio (specified low-power radio) that does not require a license. Alternatively, display device 151 may be configured to allow a portable external storage device such as a USB memory or an SD memory card to be detachably attached, and may play video data stored in the portable external storage device and display the image on light-emitting screen 151a.

[0048] It is preferable that the image displayed on the light-emitting screen 151a of the display device 151 constituting the display surface G1 be an image that has a relaxing effect on people. The image that has a relaxing effect on people is, for example, an environmental image depicting nature such as mountains, forests, woods, sky, stars, the moon, twilight, sunlight filtering through the trees, a bonfire, or the sea. The image that has a relaxing effect on people may also be a healing image with changing colors and shapes. People in the air-conditioned space 9 (see FIG. 12) can relax by looking at the display surface G1.

[0049] In addition, the air blower 1 can further improve the relaxing effect on people in the air-conditioned space 9 (see Figure 12) by displaying an image that has a relaxing effect on people on the display surface G1 while varying the amount of air blown out from the air outlet 13h with 1 / f fluctuations.

[0050] As shown in (2.6) and (2.7), the air blower 1 has a function of blowing air into the air-conditioned space 9 and a function of displaying information in the air-conditioned space 9. By displaying an image on the display surface G1, the air blower 1 induces a person who sees the image to move below the air blower 1. A person who moves below the air blower 1 feels relaxed due to the airflow blown out from the air blower 1, particularly the airflow fluctuating with 1 / f fluctuation, and the environmental image displayed on the display surface G1.

[0051] (2.8) Standard dimensions The blower 1 is arranged on a rectangular grid 95 formed by a plurality of T-bars 92 arranged in a lattice pattern as shown in Fig. 12. Therefore, it is preferable that the outer periphery of the frame 132 of the housing 13 has dimensions corresponding to the standard dimensions of the grid 95.

[0052] The standard dimensions of the grid 95 are, for example, 600 mm x 600 mm. In this case, the frame 132 is preferably a square frame, and is formed to have a size slightly smaller than the outer dimensions of 600 mm x 600 mm. Therefore, when the air blower 1 is fitted into the grid 95, it is possible to reduce the sense of incongruity of the frame 132 fitted into the grid 95, thereby improving the design of the system ceiling.

[0053] (2.9) Selection of air blower Furthermore, when a plurality of blower devices 1 are installed, it is preferable that each blower device 1 performs the following operations.

[0054] The operator operates terminal device 8 to select one of the multiple air blowers 1, and terminal device 8 transmits an apparatus selection signal including identification information (apparatus identification information) of the selected air blower 1. In each of the multiple air blowers 1, if the apparatus identification information included in the apparatus selection signal received by communication unit 16 matches the apparatus identification information of the own apparatus, display device 151 causes the image displayed on light-emitting screen 151a (display surface G1) to blink.

[0055] Therefore, the air blower 1 can notify the operator of its own presence, and as a result, the operator can easily find the air blower 1 he or she is looking for from among a plurality of air blowers 1.

[0056] (3) First Modification The air blower 1A of the first modified example further includes a discharge device 2 as shown in FIG.

[0057] The discharge device 2 is disposed in the flow path 136. In FIG. 13, the discharge device 2 is disposed in the flow path 136, between the side surface of the cover 11 and the side surface of the housing 13. The discharge device 2 adds an active ingredient to air flowing through the flow path 136 toward the blower 12. The blower 12 draws in air containing the active ingredient through the flow path 136 and expels the air containing the active ingredient into the internal space 130. As a result, the air containing the active ingredient is rectified by the rectifying vane 15, and then blown downward from the air outlet 13h, and the air containing the active ingredient is supplied to the air-conditioned space 9 (see FIG. 12).

[0058] Specifically, the discharge device 2 has a pair of electrodes, one of which holds water. The discharge device 2 applies a voltage between the pair of electrodes, generating a discharge between the pair of electrodes, thereby generating radicals as active ingredients and electrostatically atomizing the water held by the electrodes. The discharge device 2 thus generates nanometer-sized charged fine water particles containing radicals in the electrostatically atomized water droplets. The radicals are the basis for providing useful effects in a variety of situations, including sterilization, deodorization, moisturization, freshness preservation, and virus inactivation.

[0059] Alternatively, the discharge device 2 may generate a discharge between a pair of electrodes without holding water in the electrodes. In this case, the discharge device 2 generates air ions as an active ingredient by the discharge generated between the pair of electrodes.

[0060] The discharge device 2 may be configured to face the inner surface of at least one of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d. For example, the discharge device 2 may be configured to face the inner surface of each of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d, or the inner surface of each of the front wall 13c and the rear wall 13d.

[0061] (4) Second Modification Fig. 14 shows a block diagram of a blower device 1B of a second modified example. The blower device 1B is configured by further providing a communication unit 16 and a control unit 17 to the blower device 1 of the embodiment. Note that the block diagram shown in Fig. 14 is a diagram particularly for explaining the operation of the blower device 1B, and does not show all of the components of the blower device 1B.

[0062] In addition to the two fans 12 and the display device 151, the air blowing device 1B further includes a communication unit 16 and a control unit 17. The control unit 17 has an air blowing control unit 17a and an image switching unit 17b.

[0063] The communication unit 16 has at least a wireless communication interface function for receiving wireless signals. The wireless communication is preferably wireless communication conforming to standards such as Wi-Fi, Bluetooth, ZigBee, or low-power wireless communication that does not require a license (specified low-power wireless). Note that the communication unit 16 may not only receive wireless signals but also transmit wireless signals.

[0064] The control unit 17 preferably includes a computer system. That is, in the control unit 17, a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) reads and executes programs stored in memory, thereby realizing some or all of the functions of the control unit 17. The control unit 17 mainly includes a processor that operates according to a program. The type of processor is not important as long as it can realize functions by executing a program. The processor is composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or an LSI (Large Scale Integration). Although the terms IC and LSI are used here, the names may vary depending on the degree of integration, and may also be called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Field programmable gate arrays (FPGAs), which are programmed after LSI fabrication, or reconfigurable logic devices that can reconfigure the connections within the LSI or set up circuit partitions within the LSI, can also be used for the same purpose. Multiple electronic circuits may be integrated on a single chip or on multiple chips. The plurality of chips may be arranged in a concentrated manner or in a dispersed manner.

[0065] The air blowing control unit 17a controls the operation of each of the two fans 12 individually, thereby controlling the amount of air blown out from each of the two fans 12.

[0066] Image switching unit 17b switches the image to be displayed on light-emitting screen 151a (display surface G1) of display device 151 to one of a plurality of images. For example, display device 151 accesses an external image database, selects one image from a large number of images stored in the image database, and displays it on light-emitting screen 151a. Then, image switching unit 17b instructs display device 151 which image to display. Display device 151 displays the instructed image on light-emitting screen 151a.

[0067] Then, the control unit 17 controls the two fans 12 and the display device 151 based on the control signal received by the communication unit 16.

[0068] Specifically, an operator who manages air blower 1B carries terminal device 8. Terminal device 8 is, for example, a tablet terminal, a smartphone, or a dedicated terminal. The operator operates terminal device 8 to send various control signals to communication unit 16 of air blower 1B. Examples of the various control signals include an air blow control signal, a video control signal, and an air blow mode control signal. As an example, terminal device 8 displays a web browser screen or an application screen, and the operator causes terminal device 8 to send various control signals by operating the browser screen or the application screen.

[0069] The air blowing control signal is a control signal for controlling the amount of air blown by air blowing device 1B. When communication unit 16 of air blowing device 1B receives the air blowing control signal, air blowing control unit 17a controls the operation of each of two air blowers 12 individually based on the air blowing control signal, thereby adjusting the amount of air blown out from each of two air blowers 12.

[0070] The airflow mode control signal is a control signal for controlling the airflow mode of the fan 12. The two fans 12 included in the fan device 1B can operate in any of a plurality of predetermined airflow modes. In this embodiment, the plurality of airflow modes are a first airflow mode, a second airflow mode, and a third airflow mode. The first airflow mode is a mode in which the two fans 12 operate independently. The second airflow mode is a mode in which the two fans 12 operate in synchronization with each other. The third airflow mode is a mode in which at least one of the two fans 12 draws air from the interior space 130 through the air intake 13g. In this case, the airflow control unit 17a selects one of the plurality of airflow modes based on the airflow mode instruction signal and operates the two fans 12 in the selected airflow mode.

[0071] The first air blowing mode is an air blowing mode in which the two fans 12 operate independently. When the two fans 12 are operating in the first air blowing mode, the operator can operate the terminal device 8 to individually adjust the amount of air blown out from each of the two fans 12.

[0072] The second airflow mode is an airflow mode in which two fans 12 operate in synchronization with each other. When two fans 12 operate in the second airflow mode, the amount of air discharged from each of the two fans 12 is adjusted in synchronization with each other according to a predetermined pattern. For example, when fans 121 and 122 periodically vary their airflow rates, the operations of fans 121 and 122 are synchronized so that the timing at which the airflow rate of fan 121 reaches its maximum coincides with the timing at which the airflow rate of fan 122 reaches its minimum, and the timing at which the airflow rate of fan 121 reaches its minimum coincides with the timing at which the airflow rate of fan 122 reaches its maximum. Alternatively, the operations of the fans 121 and 122 are synchronized so that the timing when the air volume of the fan 121 reaches a maximum coincides with the timing when the air volume of the fan 122 reaches a maximum, and the timing when the air volume of the fan 121 reaches a minimum coincides with the timing when the air volume of the fan 122 reaches a minimum.

[0073] The third blowing mode is a blowing mode in which at least one of the two blowers 12 draws air from the internal space 130 through the air intake port 13g. The blower 12 can draw air from the internal space 130 through the air intake port 13g by reversing the rotation direction of the impeller 12a. Therefore, in the third blowing mode, the impellers 12a of the blowers 121 and 122 rotate in the reverse direction, and the blowers 121 and 122 draw air from the internal space 130. Note that one of the blowers 121 and 122 may rotate its impeller 12a in the forward direction to discharge air into the internal space 130, and the other of the blowers 121 and 122 may rotate its impeller 12a in the reverse direction to draw air from the internal space 130.

[0074] The video control signal is a control signal that instructs display device 151 to display a video on luminescent screen 151a. For example, the video control signal instructs one of a large number of video data stored in a video database as the video to be displayed. When communication unit 16 of blower device 1B receives the video control signal, video switching unit 17b instructs display device 151 to display a video based on the video control signal. Display device 151 downloads the instructed video from the video database and displays it on luminescent screen 151a.

[0075] Therefore, the air blowing device 1B can perform air blowing and display operations in response to operations on the external terminal device 8 by further including the communication unit 16, the air blowing control unit 17a, and the video switching unit 17b.

[0076] Moreover, the air blowing device 1B can flexibly change the pattern of the air blowing operation by operating in one of a plurality of air blowing modes.

[0077] (5) Third Modification Fig. 15 shows a block diagram of a blower device 1C of a third modified example. The blower device 1C is configured by adding an opening / closing member 3 and an opening / closing control unit 17c to the blower device 1B of the second modified example. Note that the block diagram shown in Fig. 15 is a diagram particularly for explaining the operation of the blower device 1C, and does not show all of the components of the blower device 1C.

[0078] The opening / closing member 3 is a so-called flap in the shape of a flat plate, and is driven to open and close by a driving means such as a motor or a cylinder (not shown). As shown in Figures 16 and 17, the opening / closing member 3 is attached to the inner surfaces of the left wall 13a, right wall 13b, front wall 13c, and rear wall 13d of the housing 13, respectively, and is configured to rotate (displace) between an open state in which the communication portion 135 is opened and a closed state in which the communication portion 135 is closed. The communication portion 135 corresponds to a gap between the periphery of the rectifying vane 15 and the inner surface of the housing 13. Note that Figures 16 and 17 show the opening / closing member 3 attached to the front wall 13c and rear wall 13d.

[0079] The control unit 17 of the air blower 1C further includes an opening / closing control unit 17c. The opening / closing control unit 17c controls the driving means of the opening / closing member 3 to control the opening and closing operation of the opening / closing member 3. The opening / closing control unit 17c controls the opening and closing operation of the opening / closing member 3 to control the direction of the air blown out from the air outlet 13h.

[0080] For example, as shown in Fig. 16, the opening / closing control unit 17c opens the opening / closing members 3 attached to the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d. In this case, the air blown out from the air outlet 13h becomes a surface airflow (downflow surface airflow) blown out directly below the air outlet 13h (see arrows F1 and F2 in Fig. 16).

[0081] 17, the opening / closing control unit 17c opens the opening / closing member 3 attached to the front wall 13c and closes the opening / closing members 3 attached to the left wall 13a, the right wall 13b, and the rear wall 13d. In this case, air flows through the communication portion 135 along the front wall 13c, but does not flow through the communication portions 135 along the left wall 13a, the right wall 13b, and the rear wall 13d. Therefore, air blows out from the air outlet 13h from the front to the rear of the air outlet 13h (see arrow F3 in FIG. 17).

[0082] As described above, the blower device 1C is provided with the open / close member 3, and thus can control the direction of the air blown out from the blower opening 13h.

[0083] (6) Fourth Modification Fig. 18 shows a block diagram of a blower device 1D of the fourth modified example. The blower device 1D is configured by adding a rectifying plate drive unit 41, an opening / closing member 42, and an elevation control unit 17d to the blower device 1B of the second modified example. Note that the block diagram shown in Fig. 18 is a diagram particularly for explaining the operation of the blower device 1D, and does not show all of the components of the blower device 1D.

[0084] The rectifying vane driving unit 41 moves the rectifying vane 15 up and down along the Z axis by a driving means such as a motor or a cylinder (see FIGS. 19 and 20). That is, the rectifying vane driving unit 41 moves the rectifying vane 15 along the opposing direction of the air intake port 13g and the air outlet 13h.

[0085] The opening / closing member 42 is a so-called flap in the shape of a flat plate, and is driven to open and close by a driving means such as a motor or a cylinder (not shown). As shown in FIGS. 19 and 20 , the opening / closing member 42 is a rectangular frame 132a configured to be rotatable relative to an edge 132b of the frame body 132. When the opening / closing member 42 is closed and aligned horizontally (in a direction along the XY plane), the opening / closing member 42 (rectangular frame 132a) functions as the throttle section 13i. When the opening / closing member 42 rotates downward and opens, the periphery of the opening 13f of the case 131 becomes the periphery of the air outlet 13h. That is, the opening / closing member 42 is attached to each of the four sides of the edge 132b of the frame body 132 and is configured to rotate (displace) between an open state in which the periphery of the opening 13f is open and a closed state in which the periphery of the opening 13f is closed and the opening / closing member 42 functions as the throttle section 13i. 19 and 20 show the opening / closing members 42 attached to the front and rear edges of the rectangular frame-shaped edge portion 132b.

[0086] The control unit 17 of the blower device 1D further includes a lift control unit 17d. The lift control unit 17d controls the drive means to control the lifting and lowering operation of the rectifying vane drive unit 41 and the opening and closing operation of the opening and closing member 42. The lift control unit 17d controls the lifting and lowering operation of the rectifying vane drive unit 41 and the opening and closing operation of the opening and closing member 42, thereby controlling the airflow area of ​​the air blown out from the air outlet 13h.

[0087] 19, for example, the elevation control unit 17d moves the rectifying vane 15 to the upper limit position and closes the opening / closing member 42. In this case, the rectifying vane 15 is located within the internal space 130, and the opening / closing member 42 functions as the restricting unit 13i, so that the air blowing out from the air outlet 13h can be prevented from being excessively diffused. In other words, the air blowing out from the air outlet 13h can be made into a concentrated airflow.

[0088] 20, the elevation control unit 17d moves the rectifying vane 15 to the lowest position and opens the opening / closing member 42. In this case, the rectifying vane 15 descends below the air outlet 13h and is positioned outside the internal space 130, and the opening / closing member 42 opens the periphery of the opening 13f, causing the air blowing device 1D to diffuse the air blown out from the air outlet 13h. That is, the air blowing device 1D can turn the air blown out from the air outlet 13h into a diffused airflow.

[0089] (7) Fifth Modification 21 to 29 show a blower device 1E according to a fifth modified example.

[0090] As shown in FIGS. 21 to 23, the air blower 1E includes a projection panel 152 as the rectifying plate 15 instead of the display device 151. The projection panel 152 is rectangular, with the upper surface of the projection panel 152 being the first surface 15a and the lower surface of the projection panel 152 being the second surface 15b. The lower surface of the projection panel 152 is provided with a projection surface 152a. The projection surface 152a is a surface onto which an image is projected via the air outlet 13h, and constitutes the display surface G1. It is preferable that a screen fabric that reflects the projected image is attached to the projection surface 152a, for example.

[0091] 30 shows an air blowing system VS1 including an air blowing device 1E. In addition to the air blowing device 1E, the air blowing system VS1 also includes a projector device 7. The projector device 7 is placed on the floor or a stand of the air-conditioned space 9. The projector device 7 projects an image onto a projection surface 152a (display surface G1) of the air blowing device 1E installed above the air-conditioned space 9.

[0092] People inside the air-conditioned space 9 can view the image projected onto the projection screen 152a through the air outlet 13h.

[0093] Projector device 7 accesses an external video database, selects one video from a large number of videos stored in the video database, and projects the selected video onto projection surface 152a. Preferably, an operator operates terminal device 8 to transmit a video control signal to projector device 7. Upon receiving the video control signal, projector device 7 downloads the specified video from the video database and projects the downloaded video onto projection surface 152a.

[0094] The blower device 1E having the above-described configuration can reduce the dimension along the Z axis (height dimension) by including the projection panel 152 instead of the display device 151. That is, the blower device 1E can further reduce its size while having a display function for displaying images in addition to a blowing function.

[0095] (8) Sixth Modification The air blower 1F in FIGS. 31 and 32 is the air blower 1E of the fifth modified example further provided with a light source 5.

[0096] The light source 5 is disposed above the projection panel 152A (rectifier plate 15) in the internal space 130 so as to face the first surface 15a of the projection panel 152A. The light source 5 is, for example, a long, rod-shaped bar light, and includes a plurality of solid-state light-emitting elements such as LEDs (Light Emitting Diodes), organic electroluminescence (OEL), or laser diodes. In the air blower 1F, the longitudinal direction of each of the three light sources 5 is along the Y axis, and the three light sources 5 are aligned along the X axis. The light source 5 is turned on by AC power or DC power supplied from a power system (not shown), and emits illumination light downward.

[0097] In the air blower 1F, the upper surface of the projection panel 152A is the first surface 15a, and the lower surface of the projection panel 152A is the second surface 15b. The projection panel 152A emits light incident on the first surface 15a from the second surface 15b. The projection panel 152A also reflects light incident on the second surface 15b. That is, the projection panel 152A functions as a light-transmitting panel for light incident on the first surface 15a and as a reflecting panel for light incident on the first surface 15a. Therefore, the illumination light emitted by the light source 5 passes through the projection panel 152A, exits from the projection surface 152a (display surface G1), and is irradiated downward from the air outlet 13h. Furthermore, since the projection panel 152A also functions as a diffusion panel, the illumination light emitted from the projection surface 152a (display surface G1) becomes diffused light, thereby improving the relaxation effect of the illumination light. That is, the air blower 1F is further provided with a light source 5 arranged in the internal space 130 and emitting illumination light, and the illumination light is emitted from the display surface G1 toward the air outlet 13h, and the illumination light emitted from the display surface G1 becomes diffused light.

[0098] Furthermore, projection plate 152A functions as a reflector for light incident on first surface 15a, and first surface 15a becomes projection surface 152a (display surface G1).

[0099] Fig. 33 shows a block configuration of air blower 1F. Control unit 17 of air blower 1F includes air blow control unit 17a, lighting control unit 17e, and operation mode switching unit 17f. Note that the block configuration shown in Fig. 33 is a diagram particularly for explaining the operation of air blower 1F, and does not show all of the components of air blower 1F.

[0100] The lighting control unit 17e controls the lighting and extinguishing of the light source 5 by instructing the light source 5 to be in a lighting state. That is, the light source 5 is turned on or off by the lighting control unit 17e. If the light source 5 is a dimmable light source, the light source 5 is dimmed by the lighting control unit 17e. If the light source 5 is a color-adjustable light source, the light source 5 is color-adjusted by the lighting control unit 17e.

[0101] The operation mode switching unit 17f selects one of a plurality of operation modes, including a video mode in which an image is displayed on the display surface G1, and an illumination mode in which illumination light is emitted from the display surface G1, in response to the operation mode signal.

[0102] The operator operates terminal device 8 to select a desired operation mode from a plurality of operation modes, and terminal device 8 transmits an operation mode signal instructing the selected operation mode to blower device 1F. When communication unit 16 of blower device 1B receives the operation mode signal, operation mode switching unit 17f switches the operation mode of blower device 1F to the operation mode instructed by the operation mode signal.

[0103] Specifically, when the video mode is instructed, the lighting control unit 17e controls to turn off the light source 5. Meanwhile, the projector device 7 also receives the operation mode signal, and when the video mode is instructed, it projects an image onto the projection surface 152a (display surface G1). That is, in the video mode, the light source 5 is turned off and an image is displayed on the projection surface 152a.

[0104] Furthermore, when the lighting mode is instructed, the lighting control unit 17e controls the lighting of the light source 5. Meanwhile, when the projector device 7 also receives the operation mode signal and is instructed to switch to the lighting mode, it stops projecting an image onto the projection surface 152a (display surface G1). That is, in the lighting mode, the light source 5 is turned on, and no image is displayed on the projection surface 152a.

[0105] The operation modes are not limited to the video mode and lighting mode described above, and may be other than the video mode and lighting mode, and the number of operation modes that can be specified may be three or more.

[0106] Furthermore, the lighting control unit 17e may control the light source 5 in accordance with the airflow generated by the air blower 1.

[0107] For example, the light source 5 is adjusted in brightness or color according to the volume of air blown out by the air blower 1. Specifically, the greater the volume of air blown out by the air blower 1, the greater the output of the illumination light from the light source 5. Alternatively, the greater the volume of air blown out by the air blower 1, the closer the illumination light from the light source 5 is to red, and the smaller the volume of air blown out by the air blower 1, the closer the illumination light from the light source 5 is to blue.

[0108] Furthermore, in the above-mentioned (3) first variant, when the discharge device 2 is operating and the air blown out from the blower device 1 contains active ingredients, the color of the illumination light from the light source 5 is adjusted, and for example, blue illumination light is irradiated into the air-conditioned space 9.

[0109] (9) Seventh Modification The image displayed on the display surface G1 may be an image other than the environmental image and the healing image.

[0110] For example, the image displayed on display surface G1 is an image that notifies the status of a person positioned below air blower 1 using a message, symbol, color, or the like. In this case, the management system including air blower 1 acquires identification information (person identification information) of the person positioned below air blower 1, and displays an image on display surface G1 that notifies the status of the person corresponding to the acquired person identification information. The management system performs authentication processing of the person in air-conditioned space 9 and status determination processing of the person in air-conditioned space 9 based on schedule information, images captured by a camera in air-conditioned space 9, information from an information terminal carried by the person, and the like, and manages the person's status in association with the person identification information.

[0111] The state of a person may be, for example, on the phone, in a remote meeting, on a break, at work, etc. In this case, a person in the air-conditioned space 9 can easily know the state of the people around them in the air-conditioned space 9, and can take action (talk to them, keep quiet, move, etc.) according to the state of the people around them.

[0112] The image displayed on the display surface G1 may also be a message for people in the air-conditioned space 9. For example, images such as a welcome message, an emergency message, a business notice, and a news message may be displayed on the display surface G1.

[0113] (10) Eighth Modification Each of the above-mentioned controls, such as airflow control, video switching, wind direction control, wind zone control, airflow mode switching, operation mode switching, and lighting control, may be manual control using a smartphone, tablet terminal, or an operating device installed on the wall of the air-conditioned space 9, or automatic control using various sensors installed in the air-conditioned space 9. The sensors include human body detection sensors (infrared sensors, camera image sensors, thermal image sensors, etc.), temperature sensors, humidity sensors, air quality sensors, and carbon dioxide sensors. Furthermore, each of the above-mentioned controls may be coordinated control according to the status of other equipment (air conditioning equipment, lighting equipment, etc.).

[0114] The rectifying vane 15 may also be configured to be movable along the XY plane. In this case, the rectifying vane 15 can be moved along the XY plane within the internal space 130 by a drive mechanism having an electric actuator or the like, and the slide position, which is the position of the rectifying vane 15 on the XY plane, can be varied. By changing the slide position of the rectifying vane 15, the directionality of the air blown out from the air outlet 13h of the air blower 1, 1A-1F can be controlled.

[0115] Furthermore, the constricted portion 13i may be configured to constrict the portion of the internal space 130 on the side of the air outlet 13h so as to narrow the internal space 130 toward the periphery of the air outlet 13h. For example, the constricted portion 13i may be shaped so that the internal space 130 gradually widens from the periphery of the air outlet 13h upward.

[0116] Moreover, although the current plate 15 is a single plate member, a plurality of plate members may be used as the current plate.

[0117] Furthermore, the structure to which the air blowers 1, 1A-1F are attached is not limited to the ceiling 91, but may be another structure such as a stand provided above the air-conditioned space 9.

[0118] Furthermore, the configurations of the above-described embodiment and each of the modified examples can be combined as appropriate, and the effects of each configuration can be similarly obtained.

[0119] (11) Environmental control system 34 is a block diagram showing an environmental conditioning system ES1. The environmental conditioning system ES1 includes a blower 1G and a control system CS1. Preferably, the environmental conditioning system ES1 further includes an imaging device C1. The blower 1G is a combination of the functions of any one of the above-described blowers 1, 1A-1F, or at least two of the above-described blowers 1, 1A-1F.

[0120] The air blower 1G is installed above the air-conditioned space 9. The air blower 1G blows air from an air outlet 13h into an air-blowing area R1 below the air blower 1G, generating an airflow in the air-blowing area R1. The air blower 1G also displays an image on a display surface G1, allowing a user H1 present in the air-blowing area R1 and a person H2 present in the air-conditioned space 9 to see the image.

[0121] The imaging device C1 captures an image of at least a part of the air-conditioned 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 black and white video, but may also be a still image.

[0122] When the control system CS1 receives an image captured by the imaging device C1, it performs airflow control and video control based on the captured image. The airflow control controls the air blowing device 1G to control the air blown out from the air outlet 13h toward the air-blowing area R1. The video control controls the video displayed on the display surface G1 by controlling the air blowing device 1G or the projector device 7 (see FIG. 30).

[0123] Specifically, the control system CS1 estimates the movements and states of a user H1 present in the air blowing area R1 and a person H2 present in the air-conditioned space 9 based on the captured images. The control system CS1 estimates the movements and states of the user H1 and person H2 appearing in the captured images using a learning model constructed by machine learning such as deep learning. The learning model is preferably constructed by deep learning using fully convolutional networks (FCN) or convolutional neural networks (CNN). The machine learning uses the captured images for learning and the movements and states of the user H1 and person H2 appearing in the captured images for learning as training data. The learning model may also use other algorithms such as a support vector machine. When analyzing the captured images of the imaging device C1, software equipped with a predetermined image processing algorithm is used as image processing software. However, this software is not limited to software built into the imaging device C1 or an interface near the imaging device C1, and may also rely on image processing and analysis technology provided by external AI (artificial intelligence) connected to the control system CS1.

[0124] The control system CS1 then performs airflow control and video control based on the estimated results of the movement and state of at least one of the user H1 and the person H2.

[0125] That is, the environment adjustment system ES1 further includes an imaging device C1 that captures an image of a user H1 present in the air blowing area R1. The control system CS1 switches the image displayed on the display surface G1 according to the results of analyzing the behavior or state of the user H1 from the captured image captured by the imaging device C1. The control system CS1 also controls the air blown out from the air outlet 13h toward the air blowing area R1 according to the results of analyzing the behavior or state of the user H1 from the captured image captured by the imaging device C1.

[0126] Assuming that the air-conditioned space 9 is a working space in an office with a free address system, the air conditioning control and video control of the control system CS1 in the air-conditioned space 9 will be explained below with reference to Fig. 35. In this case, the ventilation area R1 is a space where users work or take breaks, and office furniture such as desks and chairs are installed in the ventilation area R1.

[0127] The control system CS1 operates in one of the control modes of stages ST1-ST6 in Figure 35. In the selection stage ST1 below (11.1) and the preparation stage ST2 below (11.2), for example, employees can choose any vacant seat on the office floor and sit there while working. The concentration stage ST3 below (11.3), the chat stage ST4 below (11.4), and the creation stage ST5 below (11.5) aim to increase work productivity and efficiency while incorporating relaxing scenes, for example. Furthermore, the cleaning stage ST6 below (11.6) is designed to take measures against infectious diseases, for example.

[0128] (11.1) Selection Stage ST1 When the state of the air blowing area R1 becomes a specific state, the control system CS1 displays, as video control, a video on the display surface G1 that advises that use of the air blowing area R1 is recommended.

[0129] Specifically, when cleaning of the air blowing area R1 is completed in the cleaning stage ST6 described below (corresponding to a specific state of the air blowing area R1), the control system CS1 switches the control mode to the selection stage ST1. When the control system CS1 sets the control mode to the selection stage ST1, it displays on the display surface G1 a message that the user may use the air blowing area R1. The image displayed on the display surface G1 in the selection stage ST1 is, for example, an image of a message such as "Available for use" and an image in a color (for example, blue) that allows the user to intuitively recognize that the air blowing area R1 is available for use.

[0130] In this modification, user H1 sits in the air blowing area R1 of air blowing device 1G, which displays on display surface G1 that it is OK to use the air blowing area R1. Once user H1 sits in air blowing area R1, user H1 begins work. Therefore, user H1 can easily recognize the available space and feels a sense of security.

[0131] A fan 1G is installed above a user H1 seated in the fan area R1. The user H1 can adjust the strength and direction of the airflow from the fan 1G by executing an application pre-installed on a tablet device, smartphone, or laptop computer that the user H1 carries. By executing the application, the user H1 can also change the image displayed on the display surface G1 of the fan 1G to an image of his / her choice. The user H1 can also set the content of the message to be displayed on the display surface G1 of the fan 1G.

[0132] (11.2) Preparation Stage ST2 The control system CS1 operating in the selection stage ST1 switches the control mode from the selection stage ST1 to the preparation stage ST2 when the time that the user H1 has been staying in the air blowing area R1 reaches or exceeds the time threshold. When the time that the user H1 has been staying in the air blowing area R1 reaches or exceeds the time threshold, the control system CS1 operating in the preparation stage ST2 starts an air blowing operation to blow air out of the air outlet 13h of the air blower 1G as air blowing control.

[0133] In this modification, the image capture device C1 captures an image of at least a portion of the air-conditioned space 9 including the air-blowing area R1, and the control system CS1 receives the image captured by the image capture device C1 and measures the elapsed time since the user H1 sat down in the air-blowing area R1 based on the image. When the elapsed time reaches a time threshold, the control system CS1 controls the airflow of the air blower 1G to cause air to be blown out from the air outlet 13h of the air blower 1G.

[0134] In the preparation stage ST2, the environmental adjustment system ES1 generates an air current in the ventilation area R1, thereby supporting the concentration of the user H1 who is about to start work in the ventilation area R1.

[0135] Furthermore, when the control system CS1 detects based on the captured image that a user H1 seated in the air blowing area R1 has performed a predetermined specific action (for example, raising one hand), it may control the air blowing of the air blowing device 1G and cause the air blowing operation of the air blowing device 1G to begin.

[0136] Furthermore, the control system CS1 may measure the time that the user H1 stays in the air blowing area R1 using another person detection means such as a pyroelectric sensor that detects users in the air blowing area R1.

[0137] (11.3) Intensive Stage ST3 The control system CS1 operating in the preparation stage ST2 detects the state of the user H1 based on the captured image. Then, when the state of the user H1 is in a specific state, the control system CS1 switches the control mode from the preparation stage ST2 to the concentration stage ST3. As a video control, the control system CS1 operating in the concentration stage ST3 displays a video on the display surface G1 informing the user that communication with the user H1 will be declined.

[0138] In order to reduce the risk of infection these days, people are trying to avoid in-person meetings as much as possible, and so-called web conferencing is becoming more common. When people are seated during a web conference, it is often difficult for others to tell whether they are in a meeting or not, which can lead to people accidentally speaking to others, causing trouble for those in the conference. To prevent this problem, a message indicating that conversations are not allowed could be displayed on a screen above the room. Therefore, the Concentration Stage ST3 aims to increase work productivity by preventing people from speaking to others, which often happens during web conferences.

[0139] For example, when user H1 is in a meeting, the control system CS1 controls the video to display on the display surface G1 a video informing the user that communication with user H1 is being declined. At this time, a message such as "I am in a remote meeting. Please do not speak to me" is displayed on the display surface G1.

[0140] The control system CS1 may further include an entry / exit management function for the air-conditioned space 9. In this case, the control system CS1 stores in advance information about people who are permitted to enter the air-conditioned space 9, and when it identifies a person who has entered the air-conditioned space 9, it can read out the address information of an information terminal such as a tablet terminal or smartphone carried by that person. Then, when the control system CS1 detects person H2 approaching user H1 based on the captured image, it sends a message such as "User H1 is in a remote conference. Please do not speak to user H1" to the information terminal carried by person H2.

[0141] Therefore, the user H1 can concentrate without being disturbed by people around him.

[0142] (11.4) Chat Stage ST4 The control system CS1 operating on the concentration stage ST3 detects the state of the user H1 based on the captured image. If the state of the user H1 is not a specific state, the control system CS1 switches the control mode from the concentration stage ST3 to the chat stage ST4. As a video control, the control system CS1 operating on the chat stage ST4 displays on the display surface G1 a video that notifies the user that communication with the user H1 is possible.

[0143] For example, if the user H1 is not in a meeting, the control system CS1 controls the video to display on the display surface G1 a video that informs the user that communication with the user H1 is possible. At this time, a message such as "Welcome" is displayed on the display surface G1.

[0144] The control system CS1 may further include an entry / exit management function for the air-conditioned space 9. In this case, the control system CS1 pre-stores information about people who are permitted to enter the air-conditioned space 9, and when it identifies a person entering the air-conditioned space 9, it can read out the address information of an information terminal such as a tablet terminal or smartphone carried by that person. Then, when the control system CS1 detects person H2 approaching user H1 based on the captured image, it sends a message such as "User H1 is available for communication" to the information terminal carried by person H2.

[0145] Therefore, people H2 around the user H1 can communicate with the user H1 without disturbing the user H1.

[0146] (11.5) Creation Stage ST5 The control system CS1 operating in the concentration stage ST3 or the chat stage ST4 detects the state of the user H1 based on the captured image. Then, when the user H1 performs a specific action, the control system CS1 switches the control mode from the concentration stage ST3 or the chat stage ST4 to the creation stage ST5. The control system CS1 operating in the creation stage ST5 displays, as image control, an image that has the effect of relaxing the user H1 on the display surface G1.

[0147] For example, user H1 may lose his / her balance and become lost in thought while looking up at the ceiling. Therefore, when user H1 continues to look up at the ceiling for a predetermined period of time or more, control system CS1 displays an image that has a relaxing effect on user H1 on display surface G1. The image that has a relaxing effect on user H1 may be, for example, an environmental image depicting nature such as mountains, forests, woods, sky, stars, the moon, twilight, sunlight filtering through the trees, a bonfire, or the sea. Furthermore, the image that has a relaxing effect on user H1 may be a healing image with changing colors and shapes. User H1 can relax and refresh themselves by looking at display surface G1.

[0148] Furthermore, the control system CS1 operating in the creation stage ST5 preferably varies the amount of air discharged from the air outlet 13h of the air blower 1G with 1 / f fluctuation. The airflow fluctuating with 1 / f fluctuation allows the user H1 to feel a natural breeze, which can relax and refresh him / herself.

[0149] (11.6) Cleaning stage ST6 The control system CS1 operating in the concentration stage ST3, the chat stage ST4, or the creation stage ST5 detects the state or movement of the user H1 based on the captured image. Then, when the user H1 leaves the air blowing area R1, the control system CS1 switches the 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 operating in the cleaning stage ST6 controls the air blowing by blowing air from the air outlet 13h of the air blower 1G toward the air blowing area R1, thereby cleaning the air blowing area R1.

[0150] The control system CS1 blows away dust, dirt, and the like adhering to the desks and chairs in the ventilation area R1 by blowing air from the ventilation device 1G onto them. Therefore, when the user H1 leaves the ventilation area R1, the control system CS1 cleans the inside of the ventilation area R1 with the airflow, thereby keeping the ventilation area R1 clean.

[0151] Furthermore, it is preferable that the air blower 1G is equipped with the discharge device 2 (see FIG. 13) of the first modified example described above. In this case, the air blower 1G can generate active ingredients such as radicals, nanometer-sized charged water particles containing radicals, or air ions using the discharge device 2, and can add the active ingredients to the air blown into the air blowing area R1. As a result, it is also possible to sterilize the desks and chairs in the air blowing area R1.

[0152] Additionally, the control system CS1 operating in the cleaning stage ST6 displays on the display surface G1 that the air blowing area R1 is being cleaned. The image displayed on the display surface G1 in the cleaning stage ST6 is, for example, an image in a color that allows the user to intuitively recognize that the air blowing area R1 is unavailable. In this case, when the control system CS1 is cleaning the air blowing area R1, it is preferable to control the image so that the color of the image is a complementary or opposite color to the color of the surrounding area of ​​the display surface G1. As a result, the image displayed on the display surface G1 stands out, allowing the user H1 to easily recognize the space being cleaned and feeling a sense of security.

[0153] Furthermore, the control system CS1 operating in the cleaning stage ST6 may display a message such as "Cleaning in progress" on the display surface G1.

[0154] (11.7) Flow of each stage Basically, one cycle of the control mode of the control system CS1 is completed by transitioning in the order of selection stage ST1 → preparation stage ST2 → concentration stage ST3 → chat stage ST4 → creation stage ST5 → cleaning stage ST6. However, after the preparation stage ST2, the control system may transition to any of the concentration stage ST3, chat stage ST4, and creation stage ST5. Furthermore, the number of times each of the concentration stage ST3, chat stage ST4, and creation stage ST5 is executed in one cycle is not limited to a specific number.

[0155] In other words, it is sufficient to transition to the selection stage ST1 after the cleaning stage ST6, and the order of the concentration stage ST3, chat stage ST4, and creation stage ST5, as well as the number of times each of the concentration stage ST3, chat stage ST4, and creation stage ST5 is performed, are not limited to a specific form.

[0156] (11.8) Gestures The control system CS1 may determine at least one of the start and end of each of the above-mentioned stages based on a gesture (movement) of the user H1.

[0157] Specifically, the control system CS1 determines the gesture made by the user H1 based on the image captured by the imaging device C1. The gesture made by the user H1 is predetermined and associated with the start or end of a stage. Each of the multiple gestures is a distinguishable action. For example, the gesture corresponding to the start of the preparation stage ST2 is the action of "raising one hand." The gesture corresponding to the start of the creation stage ST5 is the action of "putting both hands behind the head." The gesture corresponding to the start of the cleaning stage ST6 is the action of "waving one hand."
