Note that 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.

In the following description, unless otherwise specified, the X-axis, Y-axis, and Z-axis are defined as being perpendicular to each other in Figure 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.

(Embodiment)
1 to 11 show a blower 1 according to the present 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.

As shown in Figure 12, the air blower 1 is mounted above the air-conditioned space 9. Above the air-conditioned space 9 is the ceiling 91 of the building. A plurality of T-bars (framework) 92 arranged in a lattice pattern are suspended from the ceiling 91 by hanging 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 x 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 hanging 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.

As shown in Figures 1 to 11, the blower device 1 comprises 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 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. 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.

The blower device 1 having the above-described configuration has expanded functionality by including a display function for displaying images in addition to its air 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 presence of the display surface G1. In other words, the blower device 1 can expand its functionality while preventing it from becoming larger.

(2) Details of the Fan Device As shown in FIGS. 2 to 5, the fan device 1 includes a cover 11, a fan 12, a housing 13, a mounting bracket 14, and a rectifying plate 15.

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

The case 131 comprises 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 the 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.

The frame body 132 has a rectangular frame 132a and an edge portion 132b, and is attached to the underside of the case 131 with screws or the like so as to surround the opening 13f on the underside of the case 131.

The rectangular frame 132a is a rectangular frame formed from a flat plate. The rectangular frame 132a extends in a direction along the X-Y plane (a plane defined by the X and Y axes) so as to narrow the 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. In other words, 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.

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

The housing 13, which includes the case 131 and frame 132 described above, has an internal space 130 surrounded by a left wall 13a, a right wall 13b, a front wall 13c, a rear wall 13d, a top wall 13e, a rectangular frame 132a, and an air outlet 13h. In other words, the housing 13 is formed in the shape of a hollow rectangular box with a rectangular air outlet 13h on its underside.

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 with the internal space 130. Air delivered by the blower 12 passes through the air intakes 13g and is blown from top to bottom into the internal space 130.

Air outlet 13h is a rectangular plane that lies along the X-Y plane (the plane defined by the X and Y axes), with the normal direction of this air outlet 13h running along the Z axis. A rectangular frame 132a that constitutes the throttling portion 13i is formed around the periphery of 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 air outlet 13h. Alternatively, the throttling portion 13i expands the internal space 130 from the periphery of air outlet 13h to the outside of air outlet 13h. In this embodiment, the throttling portion 13i extends in a brim-like manner along the X-Y plane from the lower ends of the left wall 13a, right wall 13b, front wall 13c, and rear wall 13d toward air outlet 13h.

That is, the housing 13 is formed in a box shape with 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.

The housing 13 also has an expansion space 134 in the internal space 130. The expansion space 134 is the upper space of the internal space 130, and its cross section when 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 rectifier 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 the upper part of the front wall 13c, and the rear wall 13d has an inclined wall 133d that is inclined forward at the upper part of the rear wall 13d. The expansion space 134 is formed by the inclined wall 133c and the inclined wall 133d.

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 prongs at the tip.

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

The two blowers 12 are arranged side by side along the Y axis, with the blower 12 closer to the front wall 13c being blower 121 and the blower 12 closer to the rear wall 13d being blower 122. The direction in which blower 121 blows air is opposite to the direction in which blower 122 blows air. Blower 121 blows air toward the front wall 13c (forward) (see arrow F1 in Figure 5), and blower 122 blows air toward the rear wall 13d (rearward) (see arrow F2 in Figure 5).

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

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

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.

In addition, spaces are formed between the side of the cover 11 and the side of the housing 13, and between the underside of the cover 11 and the top of the housing 13, forming air flow paths 136 for air from below the cover 11 to the blower 12 (see Figures 4 and 5). The flow path 136 ensures a gap between the underside of the cover 11 and the top of the housing 13 by using a rod-shaped spacer 11c (see Figures 4 and 5) disposed between the underside of the cover 11 and the top of the housing 13. The rectangular frame-shaped inlet 136a (see Figures 4 and 5) of the flow path 136 is formed along the entire periphery of the underside of the cover 11. When the blower 12 operates, air is drawn into the inlet 136a from below the cover 11 along the top 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 blower 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.

(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.

(2.5) Rectifying Plate The rectifying plate 15 is a rectangular plate having 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. In other words, 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.

Gaps that form communication sections 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 section 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. The communication section 135 may be formed along the entire periphery of the rectifying plate 15, or along only a pair of opposing sides along the X-axis or Y-axis.

The second surface 15b of the air straightening plate 15 is exposed below the housing 13 through the air outlet 13h. In other words, the second surface 15b can be seen from below the air blower 1 through the air outlet 13h. Therefore, the air blower 1 has a display surface G1 provided on the second surface 15b. The display surface G1 forms a display area that displays images from the air outlet 13h toward the outside of the housing 13.

Here, the rectifying plate 15 in 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 the first surface 15a and the lower surface of the display device 151 being the second surface 15b. The second surface 15b of the display device 151 is provided with a light-emitting screen 151a that emits images, 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.

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

Here, the air blower 1 is provided with a constriction portion 13i that narrows the internal space 130 toward the periphery of the air outlet 13h, thereby enhancing the directionality of the air blown out from the air outlet 13h compared to when the constriction portion 13i is not provided. In other words, the air blower 1 prevents the air blown out from the air outlet 13h from diffusing too much, allowing the air blown out from the air outlet 13h to become a concentrated airflow.

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.

Specifically, as indicated by arrow F1 in Fig. 5, air discharged by the blower 121 into the interior space 130 flows along the first surface 15a of the rectifying vane 15 toward the front wall 13c, passes through the connecting portion 135 from top to bottom, and then flows along the second surface 15b of the rectifying vane 15 toward the rear wall 13d. Also, as indicated by arrow F2 in Fig. 5, air discharged by the blower 122 into the interior space 130 flows along the first surface 15a of the rectifying vane 15 toward the rear wall 13d, passes through the connecting portion 135 from top to bottom, and then flows along the second surface 15b of the rectifying vane 15 toward the front wall 13c. The air flowing from the blower 121 along arrow F1 and the air flowing from the blower 122 along arrow F2 collide below the second surface 15b of the rectifying vane 15 (near the center of the second surface 15b in the front-to-rear direction) and is blown downward through the 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, allowing air to be blown out at a more uniform volume over a wide area below blower 1.

In addition, the internal space 130 has an expansion space 134 (see Figure 5) that expands as it approaches the air intake port 13g and the straightening vane 15, thereby preventing the creation of dead zones in the internal space 130 where almost no air flows.

Specifically, air supplied from the intake port 13g from top to bottom into the internal space 130 flows not only directly downward from the intake port 13g and strikes the first surface 15a of the air straightening vane 15, but also gradually expands as it flows downward from the intake port 13g along the expansion space 134 and strikes 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 form 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, making it unlikely that a dead zone will form 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.

It is also preferable that the amount of air discharged from the air outlet 13h fluctuates with a 1/f fluctuation. Specifically, the blower 12 fluctuates the amount of air discharged into the interior space 130 through the air intake 13g with a 1/f fluctuation by varying the rotational speed of the impeller 12a. As a result, the blower device 1 can fluctuate the amount of air discharged from the air outlet 13h with a 1/f fluctuation. People in the air-conditioned space 9 (see Figure 12) can feel the natural breeze and relax due to the airflow fluctuating with a 1/f fluctuation.

(2.7) Display The air blower 1 is equipped 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 images, and the light-emitting screen 151a constitutes the display surface G1. People in the air-conditioned space 9 can view the image displayed on the light-emitting screen 151a through the air outlet 13h.

The display device 151 is powered by AC or DC power supplied from a power grid (not shown). The display device 151 receives video data via wired or wireless communication and displays an image based on the video data on the 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 unlicensed low-power radio (specified low-power radio). Alternatively, the display device 151 may be configured to allow a portable external storage device such as a USB memory or SD memory card to be attached or detached, and may play video data stored in the portable external storage device and display the image on the light-emitting screen 151a.

It is preferable that the image displayed on the light-emitting screen 151a of the display device 151 that constitutes display surface G1 be an image that has a relaxing effect on people. Images that have a relaxing effect on people are, for example, environmental images depicting nature such as mountains, forests, woods, sky, stars, the moon, twilight, sunlight filtering through the trees, a bonfire, or the sea. In addition, images that have a relaxing effect on people may be healing images that change color and shape. People in the air-conditioned space 9 (see Figure 12) can relax by looking at display surface G1.

In addition, the air blower 1 can further enhance 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 a 1/f fluctuation.

As shown in (2.6) and (2.7), the air blower 1 has the function of blowing air into the air-conditioned space 9 and the 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 feeling of wanting to move below the air blower 1 in the viewer. 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 fluctuations, and the environmental image displayed on the display surface G1.

(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.

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 so that its external dimensions are slightly smaller than 600 mm x 600 mm. Therefore, when the blower device 1 is fitted into the grid 95, it is possible to minimize any sense of incongruity with the frame 132 fitted into the grid 95, thereby improving the design of the system ceiling.

(2.9) Selection of Fan Device Furthermore, when a plurality of fan devices 1 are installed, it is preferable that the fan device 1 performs the following operation.

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

Therefore, the air blower 1 can notify the operator of its presence. As a result, the operator can easily find the air blower 1 they are looking for from among multiple air blowers 1.

(3) First Modification A blower device 1A of a first modification further includes a discharge device 2 as shown in FIG.

The discharge device 2 is disposed in the flow path 136. In Figure 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 then adds active ingredients to the air flowing through the flow path 136 toward the blower 12. The blower 12 draws in air containing the active ingredients through the flow path 136 and expels the air containing the active ingredients into the internal space 130. As a result, the air containing the active ingredients is rectified by the rectifying vane 15, and then blown downward from the air outlet 13h, and the air containing the active ingredients is supplied to the air-conditioned space 9 (see Figure 12).

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 water particles containing radicals in the fine droplets of electrostatically atomized water. These radicals are the basis for a variety of useful effects, including sterilization, deodorization, moisturization, freshness preservation, and virus inactivation.

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

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

(4) Second Modification Fig. 14 shows a block diagram of a blower device 1B of a second modification. The blower device 1B is configured by adding 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.

In addition to the two fans 12 and the display device 151, the air blower 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.

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

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 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 primarily includes a processor that operates according to a program. The type of processor is not important as long as it can realize its 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). While ICs and LSIs are used here, the names may vary depending on the degree of integration, and may also be called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration). Field programmable gate arrays (FPGAs), which are programmed after the LSI is manufactured, 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. The electronic circuits may be integrated on a single chip or may be provided on multiple chips, and the multiple chips may be arranged in a concentrated manner or in a distributed manner.

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

The image switching unit 17b switches the image displayed on the luminous screen 151a (display surface G1) of the display device 151 to one of multiple images. For example, the display device 151 accesses an external image database, selects one image from the many images stored in the image database, and displays it on the luminous screen 151a. The image switching unit 17b then instructs the display device 151 which image to display. The display device 151 displays the instructed image on the luminous screen 151a.

The control unit 17 then controls the two fans 12 and the display device 151 based on the control signal received by the communication unit 16.

Specifically, the operator who manages the air blower 1B carries a terminal device 8. The terminal device 8 is, for example, a tablet terminal, a smartphone, or a dedicated terminal. By operating the terminal device 8, the operator sends various control signals to the communication unit 16 of the 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, the terminal device 8 displays a web browser screen or an application screen, and the operator causes the terminal device 8 to send various control signals by operating the browser screen or the application screen.

The air blowing control signal is a control signal for controlling the amount of air blown by the air blowing device 1B. 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 air blown out from each of the two air blowers 12 by individually controlling the operation of each of the two air blowers 12 based on the air blowing control signal.

The airflow mode control signal is a control signal for controlling the airflow mode of the blower 12. The two blowers 12 provided in the air blower 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 blowers 12 operate individually. The second airflow mode is a mode in which the two blowers 12 operate in synchronization with each other. The third airflow mode is a mode in which at least one of the two blowers 12 draws air from the internal 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 blowers 12 in the selected airflow mode.

The first airflow mode is an airflow mode in which the two fans 12 operate individually. When the two fans 12 are operating in the first airflow mode, the operator can individually adjust the amount of air discharged from each of the two fans 12 by operating the terminal device 8.

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

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 13g. The blower 12 can draw air from the internal space 130 through the air intake 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 expel air into the internal space 130, while 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.

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

Therefore, by further comprising a communication unit 16, an air blowing control unit 17a, and an image switching unit 17b, the air blowing device 1B can perform air blowing and display operations in response to operations on an external terminal device 8.

In addition, the blower device 1B can flexibly change the blower operation pattern by operating in one of multiple blower modes.

(5) Third Modification Fig. 15 shows a block diagram of a blower device 1C of a third modification. The blower device 1C is the same as the blower device 1B of the second modification, but further includes an opening/closing member 3 and an opening/closing control unit 17c. 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.

The opening/closing member 3 is a flat flap that is driven to open and close by a driving means such as a motor or 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 that opens the communication section 135 and a closed state that closes the communication section 135. The communication section 135 corresponds to the gap between the periphery of the straightening 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.

The control unit 17 of the blower device 1C further includes an opening/closing control unit 17c. The opening/closing control unit 17c controls the opening and closing operation of the opening/closing member 3 by controlling the drive means of the opening/closing member 3. By controlling the opening and closing operation of the opening/closing member 3, the opening/closing control unit 17c controls the wind direction of the air blown out from the air outlet 13h.

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

Also, as shown in Figure 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, right wall 13b, and 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, right wall 13b, and 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 Figure 17).

As described above, the blower device 1C is equipped with an opening/closing member 3, which allows for control of the direction of the air blown out from the air outlet 13h.

(6) Fourth Modification Fig. 18 shows a block diagram of a blower device 1D of the fourth modification. The blower device 1D further includes a rectifying vane drive unit 41, an opening/closing member 42, and an elevation control unit 17d in addition to the components of the blower device 1B of the second modification. 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.

The rectifying vane drive unit 41 uses a drive means such as a motor or a cylinder to move the rectifying vane 15 up and down along the Z axis (see Figures 19 and 20). That is, the rectifying vane drive unit 41 moves the rectifying vane 15 in the opposing direction between the air intake 13g and the air outlet 13h.

The opening/closing member 42 is a flat flap that is driven to open and close by a driving means such as a motor or cylinder (not shown). As shown in Figures 19 and 20, the opening/closing member 42 is a rectangular frame 132a that is rotatable relative to the edge 132b of the frame body 132. When the opening/closing member 42 is closed and aligned horizontally (in the X-Y plane), the opening/closing member 42 (rectangular frame 132a) functions as the throttling 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. In other words, 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 that opens the periphery of the opening 13f and a closed state that closes the periphery of the opening 13f and functions as the throttling section 13i. 19 and 20 show the opening/closing member 42 attached to the front and rear edges of the rectangular frame-shaped edge portion 132b.

The control unit 17 of the blower device 1D further includes a lifting/lowering control unit 17d. The lifting/lowering control unit 17d controls the drive means to control the lifting/lowering operation of the rectifying vane drive unit 41 and the opening/closing operation of the opening/closing member 42. The lifting/lowering control unit 17d controls the lifting/lowering operation of the rectifying vane drive unit 41 and the opening/closing operation of the opening/closing member 3, thereby controlling the wind range of the air blown out from the air outlet 13h.

For example, in Figure 19, the lift 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 positioned within the internal space 130, and the opening/closing member 42 functions as the throttling unit 13i, allowing the blower device 1D to prevent the air blown out from the air outlet 13h from diffusing too much. In other words, the blower device 1D can create a concentrated airflow by blowing out the air from the air outlet 13h.

In addition, in Figure 20, the lifting control unit 17d moves the rectifying vane 15 to its 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 blower 1D to diffuse the air blown out from the air outlet 13h. In other words, the air blower 1D can turn the air blown out from the air outlet 13h into a diffused airflow.

(7) Fifth Modification FIGS. 21 to 29 show a blower device 1E according to a fifth modification.

As shown in Figures 21-23, the air blower device 1E is provided with 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. A projection surface 152a is provided on the lower surface of the projection panel 152. The projection surface 152a is the surface onto which an image is projected via the air outlet 13h, and constitutes the display surface G1. It is preferable that the projection surface 152a is covered with, for example, a screen fabric that reflects the projected image.

Figure 30 shows an air blowing system VS1 equipped with 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 toward the projection surface 152a (display surface G1) of the air blowing device 1E installed at the top of the air-conditioned space 9.

People in the air-conditioned space 9 can view the image projected onto the projection surface 152a through the air outlet 13h.

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

The blower device 1E having the above-described configuration is equipped with a projection panel 152 instead of the display device 151, thereby reducing the dimension along the Z axis (height dimension). In other words, the blower device 1E has a display function for displaying images in addition to its blowing function, while still being able to further reduce its size.

(8) Sixth Modification A blower 1F shown in FIGS. 31 and 32 is configured by further providing a light source 5 to the blower 1E of the fifth modification.

The light source 5 is disposed above the projection panel 152A (rectifier panel 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 multiple 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 aligned along the Y axis, and the three light sources 5 are aligned along the X axis. The light source 5 is powered by AC or DC power supplied from a power system (not shown), and emits illumination light downward.

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 transmits light incident on the first surface 15a and emits it 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 translucent panel for light incident on the first surface 15a and as a reflector 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 diffuser, the illumination light emitted from the projection surface 152a (display surface G1) becomes diffused light, thereby enhancing the relaxing effect of the illumination light. That is, the blower device 1F further includes a light source 5 arranged in the internal space 130 and emitting illumination light, which 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.

In addition, the projection panel 152A functions as a reflector for light incident on the first surface 15a, causing the first surface 15a to become the projection surface 152a (display surface G1).

Figure 33 shows the block configuration of the air blower 1F. The control unit 17 of the air blower 1F includes an air blowing control unit 17a, an illumination control unit 17e, and an operation mode switching unit 17f. Note that the block configuration shown in Figure 33 is a diagram particularly for explaining the operation of the air blower 1F, and does not show all of the components of the air blower 1F.

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. Furthermore, if the light source 5 is a dimmable light source, the light source 5 is dimmed by the lighting control unit 17e. Furthermore, if the light source 5 is a color-adjustable light source, the light source 5 is color-adjusted by the lighting control unit 17e.

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

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

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

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

Note that the operating modes are not limited to the video mode and lighting mode described above. The operating modes may be other than the video mode and lighting mode, and the number of operating modes that can be instructed may be three or more.

In addition, the lighting control unit 17e may control the light source 5 according to the air flow generated by the blower device 1.

For example, the light source 5 is dimmed or adjusted in color depending on 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.

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.

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

For example, the image displayed on display surface G1 is an image that notifies the status of a person positioned below blower 1 using a message, symbol, color, or the like. In this case, the management system including blower 1 acquires identification information (person identification information) of the person positioned below blower 1, and displays an image on display surface G1 notifying 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, and information from an information terminal carried by the person, and manages the person's status in association with the person identification information.

Examples of a person's status include on the phone, in a remote meeting, on a break, and at work. In this case, a person in the air-conditioned space 9 can easily know the status of the people around them in the air-conditioned space 9, and can take action (talk to them, keep quiet, move around, etc.) according to the status of the people around them.

The image displayed on 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 display surface G1.

(10) Eighth Modification Each of the above-described 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 a human body detection sensor (such as an infrared sensor, a camera image sensor, or a thermal image sensor), a temperature sensor, a humidity sensor, an air quality sensor, and a carbon dioxide sensor. Furthermore, each of the above-described controls may be coordinated control according to the state of other equipment (such as air conditioning equipment or lighting equipment).

The rectifying vane 15 may also be configured to be movable along the X-Y plane. In this case, the rectifying vane 15 can be moved along the X-Y plane within the internal space 130 by a drive mechanism including an electric actuator or the like, making it possible to vary the slide position of the rectifying vane 15 on the X-Y plane. By changing the slide position of the rectifying vane 15, it is possible to control the directionality of the air blown out from the air outlet 13h of the blower 1, 1A-1F.

Furthermore, the constriction 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 constriction portion 13i may be shaped so that the internal space 130 gradually widens as it moves upward from the periphery of the air outlet 13h.

Furthermore, although the rectifying plate 15 is a single plate member, multiple plate members may also be used as the rectifying plate.

Furthermore, the structure to which the blower devices 1, 1A-1F are attached is not limited to the ceiling 91, but may be other structures such as a stand installed above the air-conditioned space 9.

In addition, the configurations of the above-mentioned embodiments and each modified example can be combined as appropriate, and the effects of each configuration can be obtained in the same way.

(11) Environmental Adjustment System Fig. 34 is a block diagram showing an environmental adjustment system ES1. The environmental adjustment system ES1 includes a blower 1G and a control system CS1. Preferably, the environmental adjustment 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.

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

The imaging device C1 captures an image of at least a portion 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.

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. Airflow control controls the air blower 1G to control the air blown out of the air outlet 13h toward the air blowing area R1. Video control controls the image displayed on the display surface G1 by controlling the air blower 1G or the projector device 7 (see Figure 30).

Specifically, the control system CS1 estimates the movements and states of user H1 present in the air blowing area R1 and person H2 present in the air-conditioned space 9 based on the captured images. The control system CS1 estimates the movements and states of 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 FCN (Fully Convolutional Networks) or CNN (Convolutional Neural Network). The machine learning uses the captured images for learning and the movements and states of 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 images captured by the imaging device C1, software equipped with a predetermined image processing algorithm is used as such image processing software, but this software is not limited to software built into the imaging device C1 or an interface near the imaging device C1, and may also be software that relies on image processing analysis technology from an external so-called AI (artificial intelligence) connected to the control system CS1.

Then, the control system CS1 performs air flow control and video control based on the estimated results of the movements and states of at least one of the user H1 and the person H2.

That is, the environmental 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 depending on the results of an analysis of the user H1's behavior or state from the 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 depending on the results of an analysis of the user H1's behavior or state from the image captured by the imaging device C1.

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

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), it is possible to select any vacant seat on the office floor, sit there, and work. The concentration stage ST3 below (11.3), the chat stage ST4 below (11.4), and the creative stage ST5 below (11.5) are intended to increase work productivity and efficiency, for example, by incorporating relaxing scenes. Furthermore, the cleaning stage ST6 below (11.6) is designed to implement measures against infectious diseases, for example.

(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, an image on the display surface G1 that advises that the use of the air blowing area R1 is recommended.

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 indicating 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" or an image in a color (e.g., blue) that allows the user to intuitively recognize that the air blowing area R1 can be used.

In this modified example, 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 device. Once user H1 sits in air blowing area R1, user H1 begins work. Therefore, user H1 can easily recognize the available space and feel a sense of security.

A fan device 1G is installed above user H1, who is seated in the fan area R1. User H1 can adjust the strength and direction of the airflow from fan device 1G by running an application pre-installed on a tablet device, smartphone, or laptop computer that he or she carries. Furthermore, by running the application, user H1 can switch the image displayed on the display surface G1 of fan device 1G to an image of his or her choice. User H1 can also set the content of the message to be displayed on the display surface G1 of fan device 1G.

(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. 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 when the time that the user H1 has been staying in the air blowing area R1 reaches or exceeds the time threshold.

In this modified example, the imaging device C1 captures an image of at least a portion of the air-conditioned space 9 including the air-blowing area R1. When the control system CS1 receives the image captured by the imaging device C1, it 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 blow air out of the air outlet 13h of the air blower 1G.

In the preparation stage ST2, the environmental adjustment system ES1 generates airflow in the ventilation area R1 to help user H1, who is about to start work in the ventilation area R1, concentrate.

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 start the air blowing operation of the air blowing device 1G.

In addition, the control system CS1 may use other person detection means, such as a pyroelectric sensor, to detect users within the ventilation area R1 and measure the time that user H1 stays in the ventilation area R1.

(11.3) Concentration Stage ST3
The control system CS1 operating in the preparation stage ST2 detects the state of the user H1 based on the captured image. 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.

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 online conferences are becoming more commonplace. When people are seated during an online conference, it is often difficult for those watching to tell whether they are in a meeting or whether it is okay to speak to them. This often leads to people accidentally speaking to others, causing trouble for those in the conference. To prevent this from happening, it is possible to display a message on a screen in the ceiling indicating that no one is allowed to speak to them. Therefore, the concentration stage ST3 is an attempt to increase work productivity by preventing people from speaking to others, which often happens during online conferences.

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.

The control system CS1 may also be equipped with 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 to the information terminal carried by person H2, such as "User H1 is in a remote meeting. Please do not speak to user H1."

Therefore, user H1 can concentrate without being disturbed by those around him.

(11.4) Chat Stage ST4
The control system CS1 operating in 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 in the chat stage ST4 displays on the display surface G1 a video that notifies the user H1 that communication with the user H1 is possible.

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

The control system CS1 may also be equipped with 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.

Therefore, people H2 around user H1 can communicate with user H1 without disturbing user H1.

(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.

For example, user H1 may sit upright 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 longer, control system CS1 displays an image that has a relaxing effect on user H1 on display surface G1. An 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. An image that has a relaxing effect on user H1 may also be a healing image with changing colors and shapes. User H1 can relax and refresh themselves by looking at display surface G1.

Furthermore, it is preferable that the control system CS1 operating in the creation stage ST5 fluctuates the amount of air discharged from the air outlet 13h of the blower device 1G with 1/f fluctuation. The airflow fluctuating with 1/f fluctuation allows the user H1 to feel a natural breeze, which allows them to relax and refresh.

(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 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.

The control system CS1 blows away dust, debris, and other particles 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 ventilation area R1 with the airflow, thereby keeping the ventilation area R1 clean.

It is also preferable that the air blower 1G is equipped with the discharge device 2 of the first modified example described above (see Figure 13). In this case, the air blower 1G can use the discharge device 2 to generate active ingredients such as radicals, nanometer-sized charged water particles containing radicals, or air ions, 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.

In addition, 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 the complementary or opposite color of the surrounding color of the display surface G1. As a result, the image displayed on the display surface G1 can be made to stand out, allowing the user H1 to easily recognize the space being cleaned and feeling a sense of security.

In addition, the control system CS1 operating in the cleaning stage ST6 may display a message such as "Cleaning in progress" on the display surface G1.

(11.7) Flow of Each Stage Basically, one cycle of the control mode of the control system CS1 is completed by transitioning in the following order: 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 CS1 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.

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 creative stage ST5, as well as the number of times each of the concentration stage ST3, chat stage ST4, and creative stage ST5 is performed, are not limited to any particular form.

(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.

Specifically, the control system CS1 determines the gesture made by the user H1 based on the image captured by the imaging device C1. The gestures made by the user H1 are predetermined and correspond to 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 "clasping both hands behind the head." The gesture corresponding to the start of the cleaning stage ST6 is the action of "waving one hand."
