The case 131 includes a left wall 13a, a right wall 13b, a front wall 13c, a rear wall 13d, and an upper wall 13e. Each of the left wall 13a, the right wall 13b, the front wall 13c, the rear wall 13d, and the upper wall 13e has a substantially rectangular plate shape. The upper wall 13 e forms the upper surface of the case 131 . Left wall 13 a , right wall 13 b , front wall 13 c , and rear wall 13 d extend downward from four sides of upper wall 13 e to form side surfaces of housing 13 . The lower surface of the case 131 forms a rectangular opening 13f surrounded by lower ends of the left wall 13a, right wall 13b, front wall 13c, and rear wall 13d. The left wall 13a and the right wall 13b face each other in the horizontal 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 132 has a rectangular frame 132a and an edge portion 132b, and is attached to the lower surface of the case 131 with screws or the like so as to surround the opening 13f on the lower surface of the case 131.

The rectangular frame 132a is a rectangular frame formed of a flat plate. The rectangular frame 132a extends along the XY plane (X axis and Y the plane defined by the axis). That is, the rectangular frame 132a constitutes a narrowed portion 13i that narrows the internal space 130 toward the periphery of the air blowing port 13h. A rectangular opening surrounded by the rectangular frame 132a (diaphragm portion 13i) corresponds to the air blowing port 13h.

The edge portion 132b extends obliquely downward from the outer edge of the rectangular frame 132a. The edge portion 132b extends obliquely downward so as to spread 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. As shown in FIG.

The housing 13 including the case 131 and the frame body 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, an upper wall 13e, a rectangular frame 132a, and an air outlet 13h. have That is, the housing 13 is formed in the shape of a hollow rectangular box having a rectangular air outlet 13h on the bottom surface.

Two rectangular intake ports 13g are provided in the center of the upper wall 13e. The long side of the intake port 13g is along the X-axis, and the short side of the intake port 13g is along the Y-axis. The two intake ports 13g are arranged along the Y-axis. The intake port 13g spatially connects the space above the upper wall 13e and the internal space 130 . Then, the air sent out by the blower 12 is blown downward from above into the internal space 130 through the intake port 13g.

The blower opening 13h is a rectangular plane along the XY plane (a plane defined by the X axis and the Y axis), and the normal direction of the blower opening 13h is along the Z axis. A rectangular frame 132a that constitutes the narrowed portion 13i is formed around the periphery of the blower port 13h. The narrowed portion 13i narrows the part of the internal space 130 on the side of the air blow port 13h so that the internal space 130 narrows toward the periphery of the air blow port 13h. Alternatively, the narrowed portion 13i expands the internal space 130 from the periphery of the air blow port 13h to the outside of the air blow port 13h. The constricted portion 13i of this embodiment extends like a flange 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 blower port 13h.

That is, the housing 13 is formed in a box shape having an internal space 130, and includes an intake port 13g for sending air into the internal space 130, an air blowing port 13h for discharging air from the internal space 130, and the internal space 130. is narrowed toward the periphery of the blower port 13h.

In addition, the housing 13 has an expansion space 134 in the internal space 130 . The expansion space 134 is an upper space of the internal space 130, and has a truncated quadrangular pyramid shape in cross section when viewed along the X-axis. The expansion space 134 is a space that expands from the intake port 13g as it approaches the rectifying plate 15 inside the internal space 130 . Specifically, the front wall 13c includes a rearwardly inclined wall 133c at the upper portion of the front wall 13c, and the rear wall 13d includes a forwardly inclined wall 133d at the upper portion of the rear wall 13d. An expansion space 134 is formed by the inclined wall 133c and the inclined wall 133d.

The case 131 also includes a pair of mounting pieces 13k extending leftward from the left wall 13a and a pair of mounting pieces 13k extending rightward from the right wall 13b. The attachment piece 13k has a Y-shaped flat plate shape with two bifurcated ends.

(2.2) Blower The blower 12 is a cross-flow fan that draws in the air above the housing 13 and blows it out. 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 rotational axis of the impeller 12a is along the X-axis. The blower 12 is positioned above the air intake port 13g of the upper wall 13e, and the air discharged 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. The direction in which air blower 121 blows air is opposite to the direction in which air blower 122 blows air. The blower 121 blows air toward the front wall 13c (forward) (see arrow F1 in FIG. 5), and the blower 122 blows air toward the rear wall 13d (backward) (see arrow F2 in FIG. 5).

The blower 12 is driven by AC power 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 has a rectangular box shape with an opening 11a on the bottom surface and is mainly made of a galvanized steel plate. 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.

A pair of rectangular insertion holes 11b are formed in each of the right wall and the left wall of the cover 11 . The housing 13 is positioned with respect to the cover 11 by inserting the mounting pieces 13k of the housing 13 into the insertion holes 11b.

Between the side surface of the cover 11 and the side surface of the housing 13, and between the lower surface of the cover 11 and the upper surface of the housing 13, there is a space that serves as an air flow path 136 from below the cover 11 to the blower 12. are formed (see FIGS. 4 and 5). The flow path 136 is formed between the lower surface of the cover 11 and the upper surface of the housing 13 by a rod-shaped spacer 11c (see FIGS. 4 and 5) arranged between the lower surface of the cover 11 and the upper surface of the housing 13. Secures a gap. A rectangular frame-shaped inlet 136 a (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 blower 12 operates, air is sucked into the inlet 136a from below the cover 11 along the upper surface of the edge 132b. The air that has flowed into the flow path 136 from the inlet 136 a is sucked into the blower 12 through the flow path 136 . The blower 12 discharges the air sucked through the flow path 136 into the internal space 130 through the 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 support 14b is a rod, and the lower end of the support 14b is fixed to each of the four corners of the upper surface of the mounting plate 14a. The upper end of the support 14 b is fixed to the lower surface of the upper wall 13 e of the housing 13 . That is, the mounting plate 14 a is fixed to the lower surface of the upper wall 13 e by four supports 14 b and arranged in the internal space 130 of the housing 13 . The mounting plate 14a is positioned below the two intake ports 13g in the internal space 130 and faces the two intake ports 13g along the Z-axis.

(2.5) Straightening plate The straightening plate 15 has a rectangular plate shape and includes a first surface 15a and a second surface 15b facing each other in the thickness direction. Then, 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 is in contact with the lower surface of the mounting plate 14a. That is, the straightening plate 15 is arranged 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.

Between the peripheral edge of the current plate 15 and the inner surfaces of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d of the housing 13, there are gaps that form the communicating portion 135. That is, outside the current plate 15, a communication portion 135 in the shape of a rectangular frame that connects the space on the first surface 15a side and the space on the second surface 15b side in the internal space 130 is formed. The communicating portion 135 may be formed along the entire circumference of the rectifying plate 15, or may be formed along only a pair of sides facing each other along the X-axis or the Y-axis.

The second surface 15b of the straightening plate 15 is exposed below the housing 13 through the air blowing port 13h. That is, from below the blower 1, the second surface 15b can be seen through the blower port 13h. Therefore, in the blower device 1, the display surface G1 is provided on the second surface 15b. The display surface G1 constitutes a display area for displaying an image from the blower port 13h toward the outside of the housing 13. As shown in FIG.

Here, the straightening plate 15 of this embodiment is the display device 151 . The display device 151 has a rectangular plate shape, the upper surface of the display device 151 is the first surface 15a, and the lower surface of the display device 151 is the second surface 15b. The second surface 15b of the display device 151 is provided with a light-emitting screen 151a for emitting an image, and the light-emitting screen 151a constitutes the display surface G1. That is, the display device 151 also serves as the current plate 15 and has the functions of both the current plate 15 and the display surface G1.

(2.6) Blowing Air When the blower 12 is driven, the impeller 12a rotates, and the air blown out by the blower 12 is blown from top to bottom into the internal space 130 of the housing 13 through the air inlet 13g. The air supplied downward from the intake port 13g flows toward the communication portion 135 along the first surface 15a of the current plate 15 (display device 151), and passes through the communication portion 135 from top to bottom. After that, it advances toward the air outlet 13h between the second surface 15b of the straightening plate 15 and the narrowed portion 13i, and blows downward from the air outlet 13h. The air blown out from the blower port 13h is supplied to the air-conditioned space 9 (see FIG. 12).

Here, the air blower 1 includes the narrowed portion 13i that narrows the internal space 130 toward the periphery of the air blow port 13h. It has the function of increasing That is, the blower device 1 can suppress the excessive diffusion of the air blown from the blower port 13h and make the air blown from the blower port 13h a concentrated airflow.

In addition, the blower 1 has a plurality of (two in this embodiment) air inlets 13g, and the directions in which the air is sent into the internal space 130 from the plurality of air inlets 13g are different from each other. It is possible to make the air blown out to the surface airflow.

Specifically, as indicated by arrow F1 in FIG. After passing downward from the top, it flows along the second surface 15b of the straightening plate 15 toward the rear wall 13d. 5, the air discharged by the blower 122 into the internal space 130 flows along the first surface 15a of the current plate 15 toward the rear wall 13d, and flows through the communicating portion 135 from top to bottom. After passing toward the front wall 13c, along the second surface 15b of the rectifying plate 15, it flows toward the front wall 13c. The air flowing along the arrow F1 from the blower 121 and the air flowing along the arrow F2 from the blower 122 collide below the second surface 15b of the current plate 15 (near the center of the second surface 15b in the front-rear direction), The air is blown downward from the blower port 13h. At this time, below the second surface 15b of the straightening plate 15, the air flowing along the arrow F1 and the air flowing along the arrow F2 advance in directions toward each other (opposite directions) and collide with each other. As a result, the air blown downward from the blower port 13h becomes a surface air current, and the air can be blown out in a uniform air volume over a wide area below the blower 1. FIG.

In addition, the internal space 130 has an expansion space 134 (see FIG. 5) that expands from the intake port 13g as it approaches the current plate 15, thereby suppressing the occurrence of a dead zone in the internal space 130 in which little air flows.

Specifically, the air supplied downward from the air intake port 13g into the internal space 130 not only flows directly downward from the air intake port 13g and collides with the first surface 15a of the straightening plate 15, but also It also becomes an air current that flows downward while gradually expanding along the expansion space 134 from 13 g and collides with the first surface 15 a of the straightening plate 15 . Since the expansion space 134 gradually expands as it progresses downward, a dead zone in which little air flows is less likely to occur in the upper portion of the internal space 130 . That is, the expansion space 134 has a shape obtained by cutting the upper corner of the internal space 130 , and dead zones are less likely to occur in the internal space 130 . Therefore, the air blower 1 can reduce the air pressure loss in the internal space 130 and improve the air blowing efficiency.

Also, it is preferable that the amount of air discharged from the blower port 13h fluctuates with 1/f fluctuations. Specifically, the air blower 12 fluctuates the rotation speed of the impeller 12a to fluctuate the amount of air discharged into the internal space 130 through the air inlet 13g with 1/f fluctuation. As a result, the blower device 1 can vary the amount of air discharged from the blower port 13h with 1/f fluctuation. A person in the air-conditioned space 9 (see FIG. 12) can feel the natural wind and relax due to the air current fluctuating with 1/f fluctuation.

(2.7) Display The blower device 1 includes a display device 151 as the current 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 luminous screen 151a for emitting an image, and the luminous screen 151a constitutes the display surface G1. A person in the air-conditioned space 9 can see the image displayed on the light-emitting screen 151a through the blower port 13h.

The display device 151 is driven by AC power or DC power supplied from a power system (not shown). Then, the display device 151 receives the image data through wired communication or wireless communication, and displays an image based on the image data on the light-emitting screen 151a. Wireless communication is wireless communication that conforms to standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power wireless that does not require a license (specified low-power wireless). is preferred. Alternatively, the display device 151 may have a configuration in which a portable external storage device such as a USB memory or an SD memory card can be attached and detached. An image may be displayed on the screen 151a.

The image displayed on the luminous screen 151a of the display device 151 that constitutes the display surface G1 is preferably an image that has the effect of relaxing people. Images that have a relaxing effect on people are, for example, images of nature, such as mountains, forests, forests, skies, stars, moons, dusk, sunlight filtering through trees, bonfires, and seas. Also, the image that has the effect of relaxing a person may be a healing image in which colors, shapes, and the like change. A person in the air-conditioned space 9 (see FIG. 12) can relax by looking at the display surface G1.

In addition, the air blower 1 changes the amount of air discharged from the air blowing port 13h by 1/f fluctuation while displaying an image having a relaxing action on the display surface G1, thereby reducing the air conditioning space 9 (FIG. 12). see) can further improve the relaxing effect on the person inside.

The air blower 1 has a function of blowing air to the air-conditioned space 9 and a function of displaying to the air-conditioned space 9, as in (2.6) and (2.7). Therefore, the blower device 1 displays an image on the display surface G1, thereby making the person who sees the image feel to move below the blower device 1.例文帳に追加A person who moves below the blower 1 feels relaxed due to the airflow blown out from the blower 1, especially the airflow fluctuating with 1/f fluctuation, and the environmental image displayed on the display surface G1.

(2.8) Standard Dimensions The blower device 1 is arranged on a rectangular grid 95 formed by a plurality of T-bars 92 arranged in a grid pattern as shown in FIG. Therefore, it is preferable that the dimensions of the outer periphery of the frame 132 of the housing 13 correspond 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 to have a size slightly smaller than the outer dimensions of 600 mm×600 mm. Therefore, when the blower device 1 is fitted in the grid 95, it is possible to suppress a sense of incongruity with the frame 132 fitted in the grid 95, thereby improving the design of the system ceiling.

(2.9) Selection of Blower Device When a plurality of blower devices 1 are installed, it is preferable that the blower device 1 performs the following operation.

An operator selects one of the plurality of air blowers 1 by operating the terminal device 8, and the terminal device 8 is a device including identification information (device identification information) of the selected air blower 1. Send a selection signal. In each of the plurality of 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 its own device, the display device 151 displays the emission screen 151a (display surface G1 ) flashes the image displayed.

Therefore, the blower device 1 can notify the operator of its existence. As a result, the operator can easily find the desired blower 1 among the plurality of 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 arranged in the channel 136 . In FIG. 13 , the discharge device 2 is arranged between the side surface of the cover 11 and the side surface of the housing 13 in the channel 136 . Then, the discharge device 2 adds an effective component to the air flowing through the flow path 136 toward the blower 12 . The blower 12 sucks air containing the active ingredient through the flow path 136 and discharges air containing the active ingredient into the internal space 130 . As a result, the air containing the active ingredient is rectified by the rectifying plate 15 and then blown downward from the air outlet 13h to supply the air containing the active ingredient to the air-conditioned space 9 (see FIG. 12).

Specifically, the discharge device 2 has a pair of electrodes, and water is held in one electrode of the pair of electrodes. By applying a voltage between the pair of electrodes, the discharge device 2 generates a discharge between the pair of electrodes, thereby generating radicals as an active ingredient and statically dissipating water held between the electrodes. Electro-atomize. Thus, the discharge device 2 generates nanometer-sized charged fine water particles containing radicals in the electrostatically atomized water fine droplets. Radicals are the basis for producing useful effects in various situations, not limited to sterilization, deodorization, moisturizing, freshness preservation, and virus inactivation.

Further, the discharge device 2 may generate discharge between a pair of electrodes without holding water in the electrodes. In this case, the discharge device 2 generates air ions as active ingredients by the discharge generated between the pair of electrodes.

It should be noted that the discharge device 2 may be provided facing 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 is provided facing the inner surfaces of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d; It may be any of the configurations provided.

(4) Second Modification FIG. 14 shows a block configuration of a blower device 1B of a second modification. The blower device 1B is obtained by further providing a communication unit 16 and a control unit 17 to the blower device 1 of the embodiment. Note that the block configuration shown in FIG. 14 is a diagram specifically for explaining the operation of the blower device 1B, and does not show all the components of the blower device 1B.

The blower device 1B further includes a communication unit 16 and a control unit 17 in addition to the two blowers 12 and the display device 151 . The control unit 17 has a fan control unit 17a and an image switching unit 17b.

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

The control unit 17 is preferably equipped with 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 a program stored in a memory, thereby performing part or all of the functions of the control unit 17. is realized. The control unit 17 has a processor that operates according to a program as a main hardware configuration. Any type of processor can be used as long as it can implement functions by executing a program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or LSI (Large Scale Integration). Here, they are called ICs and LSIs, but the names change depending on the degree of integration, and may be called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration). A field programmable gate array (FPGA), which is programmed after the LSI is manufactured, or a reconfigurable logic device capable of reconfiguring the connection relationships inside the LSI or setting up circuit partitions inside the LSI for the same purpose. can be done. A plurality of electronic circuits may be integrated on one chip or may be provided on a plurality of chips. A plurality of chips may be collectively arranged or distributed.

The air blow control unit 17a controls the amount of air discharged from each of the two air blowers 12 by individually controlling the operation of each of the two air blowers 12.

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

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

Specifically, the operator who manages the blower device 1B carries the terminal device 8. The terminal device 8 is, for example, a tablet terminal, a smart phone, or a dedicated terminal. The operator operates the terminal device 8 to transmit various control signals to the communication unit 16 of the blower device 1B. Various control signals include a fan control signal, a video control signal, a fan mode control signal, and the like. 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 transmit various control signals by operating the browser screen or the application screen.

The blower control signal is a control signal for controlling the amount of air blown by the blower 1B. Then, when the communication unit 16 of the blower device 1B receives the blower control signal, the blower control unit 17a individually controls the operations of the two blowers 12 based on the blower control signal, so that each of the two blowers 12 Adjust the amount of air exhaled from the

A blowing mode control signal is a control signal for controlling the blowing mode of the blower 12 . The two blowers 12 included in the blower device 1B can operate in one of a plurality of predetermined blower modes. In this embodiment, a first blowing mode, a second blowing mode, and a third blowing mode are used as the plurality of blowing modes. The first blowing mode is a blowing mode in which the two blowers 12 operate individually. The second blowing mode is a blowing mode in which the two blowers 12 operate in synchronization with each other. The third blowing mode is a blowing mode in which at least one of the two blowers 12 sucks the air in the internal space 130 through the air intake port 13g. In this case, the blower controller 17a selects one of a plurality of blower modes based on the blower mode instruction signal, and operates the two blowers 12 in the selected blower mode.

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

The second blowing mode is a blowing mode in which the two blowers 12 operate in synchronization with each other. When the two fans 12 are operating in the second fan mode, the amount of air discharged from each of the two fans 12 is synchronously adjusted in a predetermined pattern. For example, when the air volume of the

fans

121 and 122 is periodically fluctuated, the timing at which the air volume of the fan 121 reaches its maximum coincides with the timing at which the air volume of the fan 122 reaches its minimum. Each operation of the

blowers

121 and 122 is synchronized so that the timing when the air volume of the blower 122 becomes maximum coincides with the timing when the air volume of the blower 122 becomes maximum. Alternatively, the timing at which the air volume of the fan 121 reaches its maximum coincides with the timing at which the air volume of the fan 122 reaches its maximum, and the timing at which the air volume of the blower 121 reaches its minimum coincides with the timing at which the air volume of the blower 122 reaches its minimum. , the operations of the

blowers

121 and 122 are synchronized.

The third blowing mode is a blowing mode in which at least one of the two blowers 12 sucks the air in the internal space 130 through the air intake 13g. By reversing the rotation direction of the impeller 12a, the blower 12 can suck the air in the internal space 130 through the air inlet 13g. Therefore, in the third blowing mode, the impellers 12a of the

blowers

121 and 122 are reversed so that the

blowers

121 and 122 draw air from the internal space . One of the

fans

121 and 122 may rotate the impeller 12a forward to discharge air into the internal space 130, and the other of the

fans

121 and 122 may reverse the impeller 12a to suck air from the internal space 130.

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

Therefore, the blower device 1B further includes the communication unit 16, the blower control unit 17a, and the image switching unit 17b, so that the blower operation and the display operation can be performed according to the operation of the external terminal device 8.

In addition, the blower 1B can flexibly change the blowing operation pattern by operating in one of a plurality of blowing modes.

(5) Third Modification FIG. 15 shows a block configuration of a blower device 1C of a third modification. The blower device 1C is the same as the blower device 1B of the second modified example, but is further provided with an opening/closing member 3 and an opening/closing control section 17c. Note that the block configuration shown in FIG. 15 is a diagram specifically for explaining the operation of the blower device 1C, and does not show all the components of the blower device 1C.

The opening/closing member 3 is a flat plate-shaped so-called flap, and is driven to open and close by a driving means such as a motor (not shown) or a cylinder. 16 and 17, the opening/closing member 3 is attached to the inner surfaces of the left wall 13a, the right wall 13b, the front wall 13c, and the rear wall 13d of the housing 13, and serves as an opening for opening the communicating portion 135. and a closed state in which the communicating portion 135 is closed (displaced). The communicating portion 135 corresponds to the gap between the peripheral edge of the straightening plate 15 and the inner surface of the housing 13 . 16 and 17 show the opening/closing member 3 attached to the front wall 13c and the 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/closing operation of the opening/closing member 3 by controlling the driving means of the opening/closing member 3. FIG. The opening/closing control unit 17c controls the opening/closing operation of the opening/closing member 3, thereby controlling the direction of the air blown out from the air outlet 13h.

For example, as shown in FIG. 16, the opening/closing controller 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 from the air blowing port 13h becomes a surface air current (a down-flow surface air current) blowing directly below the air blowing port 13h (see arrows F1 and F2 in FIG. 16).

Further, as shown in FIG. 17, the opening/closing control part 17c opens the opening/closing member 3 attached to the front wall 13c, and is attached to each of the left wall 13a, the right wall 13b, and the rear wall 13d. The opening/closing member 3 is closed. In this case, air flows through the communicating portion 135 along the front wall 13c, but does not flow through the communicating portion 135 along the left wall 13a, the right wall 13b, and the rear wall 13d. Therefore, the air blown out from the blower port 13h is blown backward from the front of the blower port 13h (see arrow F3 in FIG. 17).

As described above, the blower device 1C is provided with the opening/closing member 3, so that it is possible to control the direction of the air blown out from the blower port 13h.

(6) Fourth Modification FIG. 18 shows a block configuration of a blower device 1D of a fourth modification. The blower device 1D is the same as the blower device 1B of the second modification, but further includes a rectifying plate driving section 41, an opening/closing member 42, and an elevation control section 17d. Note that the block configuration shown in FIG. 18 is a diagram specifically for explaining the operation of the blower device 1D, and does not show all the components of the blower device 1D.

The rectifying plate driving unit 41 moves the rectifying plate 15 up and down along the Z-axis by driving means such as a motor or a cylinder (see FIGS. 19 and 20). That is, the rectifying plate driving section 41 moves the rectifying plate 15 along the direction in which the intake port 13g and the air blowing port 13h face each other.

The opening/closing member 42 is a flat plate-shaped so-called flap, and is driven to open and close by a driving means such as a motor (not shown) or a cylinder. The opening/closing member 42 is a rectangular frame 132a configured to be rotatable with respect to the edge 132b of the frame 132, as shown in FIGS. When the opening/closing member 42 is closed and extends in the horizontal direction (the direction along the XY plane), the opening/closing member 42 (rectangular frame 132a) functions as the narrowed portion 13i. When the opening/closing member 42 rotates downward to open, the periphery of the opening 13f of the case 131 becomes the periphery of the air blowing port 13h. That is, the opening/closing member 42 is attached to each of the four sides of the edge portion 132b of the frame 132, and has an open state in which the peripheral edge of the opening 13f is opened, and a closed state in which the peripheral edge of the opening 13f is closed and functions as the diaphragm portion 13i. is configured to rotate (displace) between 19 and 20 show the opening/closing member 42 attached to the front and rear sides of the rectangular frame-shaped edge portion 132b.

The control unit 17 of the blower device 1D further includes an elevation control unit 17d. The elevation control unit 17d controls the elevation operation of the current plate driving unit 41 and the opening/closing operation of the opening/closing member 42 by controlling the driving means. The elevation control unit 17d controls the elevation operation of the straightening plate driving unit 41 and the opening/closing operation of the opening/closing member 3, thereby controlling the air range of the air blown out from the air blowing port 13h.

For example, in FIG. 19, the elevation control unit 17d moves the current plate 15 to the upper limit position and closes the opening/closing member 42 . In this case, the rectifying plate 15 is positioned in the internal space 130 and the opening/closing member 42 functions as the narrowed portion 13i, so that the air blower 1D can prevent the air blown from the air blowing port 13h from diffusing too much. That is, the air blower 1D can make the air blown from the blower port 13h into a concentrated airflow.

Also, in FIG. 20, the elevation control unit 17d moves the straightening plate 15 to the lower limit position and opens the opening/closing member 42 . In this case, the rectifying plate 15 descends below the air blow port 13h and is positioned outside the internal space 130, and the opening/closing member 42 opens the peripheral edge of the opening 13f. Diffuse the air blowing from 13h. That is, the air blower 1D can make the air blown out from the blower port 13h into a diffusion airflow.

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

As shown in FIGS. 21 to 23, the blower device 1E includes a projection plate 152 instead of the display device 151 as the straightening plate 15. FIG. The projection plate 152 has a rectangular plate shape, the upper surface of the projection plate 152 is the first surface 15a, and the lower surface of the projection plate 152 is the second surface 15b. A projection surface 152 a is provided on the lower surface of the projection plate 152 . The projection plane 152a is a plane onto which an image is projected through the blower port 13h, and constitutes the display plane G1. It is preferable that the projection plane 152a is pasted with, for example, a screen material that reflects the projected image.

FIG. 30 shows a blower system VS1 including a blower 1E. The blower system VS1 includes a projector device 7 in addition to the blower device 1E. The projector device 7 is arranged on the floor of the air-conditioned space 9 or on a stand. The projector device 7 projects an image onto the projection surface 152a (display surface G1) of the blower device 1E installed in the upper part of the air-conditioned space 9. FIG.

A person in the air-conditioned space 9 can see the image projected onto the projection surface 152a through the air blowing port 13h.

The projector device 7 accesses an external image database, selects one image from many images stored in the image database, and illuminates the projection surface 152a. Preferably, the operator operates the terminal device 8 to transmit the image control signal to the projector device 7 . Upon receiving the image control signal, the projector device 7 downloads the instructed image from the image database and projects the downloaded image onto the projection surface 152a.

The blower device 1E having the above configuration can reduce the dimension (height dimension) along the Z axis by providing the projection plate 152 instead of the display device 151. That is, the air blower 1E can further suppress an increase in size while having a display function of displaying an image in addition to the air blowing function.

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

The light source 5 is arranged above the projection plate 152A in the internal space 130 so as to face the first surface 15a of the projection plate 152A (rectifying plate 15). The light source 5 is, for example, a long rod-shaped bar light, and includes a plurality of solid light emitting devices such as LEDs (Light Emitting Diodes), organic ELs (Organic Electro Luminescence, OEL), or laser diodes. In the blower device 1F, the longitudinal direction of each of the three light sources 5 is along the Y-axis, and the three light sources 5 are arranged along the X-axis. The light source 5 is lit by AC power or DC power supplied from a power system (not shown), and emits illumination light downward.

In the blower device 1F, the upper surface of the projection plate 152A is the first surface 15a, and the lower surface of the projection plate 152A is the second surface 15b. The projection plate 152A emits light incident on the first surface 15a from the second surface 15b. Also, the projection plate 152A reflects the light incident on the second surface 15b. That is, the projection plate 152A functions as a translucent plate for the light incident on the first surface 15a, and functions as a reflector for the light incident on the first surface 15a. Therefore, the illumination light emitted by the light source 5 is transmitted through the projection plate 152A, is emitted from the projection surface 152a (display surface G1), and is emitted downward from the air blowing port 13h. In addition, since the projection plate 152A further has a function as a diffusion plate, the illumination light emitted from the projection surface 152a (display surface G1) becomes diffused light, and the relaxation effect of the illumination light can be improved. That is, the blower device 1F is arranged in the internal space 130 and further includes a light source 5 that emits illumination light. becomes diffuse light.

In addition, the projection plate 152A functions as a reflector for light incident on the first surface 15a, so that the first surface 15a becomes the projection surface 152a (display surface G1).

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

The lighting control unit 17e controls the lighting and extinguishing of the light source 5 by instructing the light source 5 to turn on. That is, the light source 5 is turned on or off by the lighting controller 17e. Further, if the light source 5 is a dimmable light source, the light source 5 is dimmed and controlled by the lighting control section 17e. Further, if the light source 5 is a light source that can be color-tuned, the color-tone control of the light source 5 is performed by the lighting control unit 17e.

The operation mode switching unit 17f selects one of a plurality of operation modes including an image mode for displaying an image on the display surface G1 and an illumination mode for emitting illumination light from the display surface G1 according to the operation mode signal. do.

The operator operates the terminal device 8 to select a desired operation mode from a plurality of operation modes, and the terminal device 8 transmits an operation mode signal indicating the selected operation mode to the blower device 1F. Then, 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, the lighting control unit 17e turns off the light source 5 when the video mode is instructed. On the other hand, when the projector apparatus 7 also receives the operation mode signal and is instructed to enter the image mode, it projects an image onto the projection surface 152a (display surface G1). That is, in the image mode, the light source 5 is turned off and an image is displayed on the projection surface 152a.

Also, the lighting control unit 17e controls the lighting of the light source 5 when the lighting mode is instructed. On the other hand, when the projector apparatus 7 also receives the operation mode signal and is instructed to enter the illumination mode, it stops projecting the 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.

Note that the operation mode is not limited to the video mode and lighting mode described above. The operation mode may be other than the video mode and lighting mode, and the number of instructable operation modes may be three or more.

Further, the lighting control unit 17e may control the light source 5 according to the airflow generated by the blower 1.

For example, the light source 5 is dimmed or colored according to the amount of air blown by the blower device 1 . Specifically, the output of the illumination light from the light source 5 is increased as the amount of air blown by the blower 1 increases. Alternatively, the larger the amount of air blown by the blower 1, the closer the illumination light of the light source 5 is to red, and the smaller the amount of air blown by the blower 1, the closer the illumination light of the light source 5 is to blue.

In addition, in the above-mentioned (3) first modification, if the discharge device 2 operates and the air blown from the blower device 1 contains an effective component, the illumination light from the light source 5 is adjusted to, for example, blue illuminating the air-conditioned space 9.

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

For example, the image displayed on the display surface G1 is an image that notifies the state of the person positioned below the blower 1 by a message, symbol, color, or the like. In this case, the management system including the blower 1 acquires the identification information (person identification information) of the person located below the blower 1, and displays an image notifying the state of the person corresponding to the acquired person identification information. It is displayed on the surface G1. The management system performs authentication processing of the person in the air-conditioned space 9 and State determination processing is performed, and the state of a person is managed in association with the person identification information.

A person's status includes, for example, being on the phone, being in a remote meeting, taking a break, and working. In this case, the person in the air-conditioned space 9 can easily know the state of the surrounding people in the air-conditioned space 9, and act according to the state of the surrounding people (talk, be quiet, move, etc.). can take

Also, the image displayed on the display surface G1 may be a message for the people in the air-conditioned space 9. For example, images such as a welcome message, an emergency notification message, a business communication notification message, and a news notification message are displayed on the display surface G1.

(10) Eighth Modified Example Each control such as the above-described airflow control, video switching, wind direction control, wind area control, ventilation mode switching, operation mode switching, and lighting control can be performed on the wall of the air-conditioned space 9 by smartphones, tablet terminals, etc. Either manual control by an installed operating device or automatic control using various sensors installed in the air-conditioned space 9 may be used. The sensors include human body detection sensors (such as infrared sensors, camera image sensors, or thermal image sensors), temperature sensors, humidity sensors, air quality sensors, and carbon dioxide sensors. Further, each control described above may be cooperative control according to the state of other devices (air conditioners, lighting devices, etc.).

Further, the current plate 15 may be configured to be movable along the XY plane. In this case, the straightening plate 15 is moved along the XY plane in 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 straightening plate 15 on the XY plane, is variable. can do. By changing the sliding position of the current plate 15, it is possible to control the directivity of the air blown from the blower ports 13h of the

blowers

1, 1A-1F.

In addition, the narrowed portion 13i may be configured to narrow the portion of the internal space 130 on the side of the air blow port 13h so that the internal space 130 narrows toward the periphery of the air blow port 13h. For example, the constricted portion 13i may have a shape that gradually widens the internal space 130 as it progresses upward from the periphery of the blower port 13h.

Further, although the current plate 15 is a single plate member, a plurality of plate members may be used as the current plate.

Also, the structure to which the

blowers

1, 1A-1F are attached is not limited to the ceiling 91, and may be another structure such as a frame provided above the air-conditioned space 9.

In addition, the configurations of the above-described embodiment and modifications can be combined as appropriate, and the effects of each configuration can be similarly obtained.

(11) Environment Adjustment System FIG. 34 is a block diagram showing the environment adjustment system ES1. The environmental adjustment system ES1 comprises a blower 1G and a control system CS1. The environment adjustment system ES1 preferably further includes an imaging device C1. The blower 1G is one of the

blowers

1, 1A to 1F, or a combination of at least two functions of the

blowers

1, 1A to 1F.

The air blower 1G is installed above the air-conditioned space 9. Then, the blower 1G blows air from the blower port 13h to the blowing area R1 below the blower 1G to generate an air current in the blowing area R1. Further, the blower device 1G can show the image to the user H1 present in the blowing area R1 and the person H2 present in the air-conditioned space 9 by displaying the image on the display surface G1.

The imaging device C1 captures an image of at least part of the air-conditioned space 9 including the ventilation area R1, and outputs the captured image to the control system CS1. The captured image is preferably a color or black and white moving image, but may be a still image.

Upon receiving the image captured by the imaging device C1, the control system CS1 performs ventilation control and image control based on the captured image. The air blowing control controls air blown from the air blowing port 13h toward the blowing area R1 by controlling the air blowing device 1G. The video control controls the video displayed on the display surface G1 by controlling the blower device 1G or the projector device 7 (see FIG. 30).

Specifically, the control system CS1 estimates the actions and states of the user H1 present in the ventilation area R1 and the person H2 present in the air-conditioned space 9 based on the captured image. The control system CS1 uses a learning model constructed by machine learning such as deep learning to estimate the actions and states of the user H1 and the person H2 appearing in the captured image. The learning model is preferably constructed by deep learning using FCN (Fully Convolutional Networks) or CNN (Convolutional Neural Network). In the machine learning, captured images for learning and motions and states of the user H1 and the person H2 appearing in the captured images for learning are used as teacher data. The learning model may also use other algorithms such as Support Vector Machine. Software having a predetermined image processing algorithm is used as such image processing software in analyzing the captured image of the imaging device C1. The image processing analysis technology is not limited to the built-in one, and may be one that relies on an external so-called AI (artificial intelligence) connected to the control system CS1 for image processing analysis technology.

Then, the control system CS1 performs ventilation control and image control based on the estimation result of the motion and state of at least one of the user H1 and the person H2.

That is, the environment adjustment system ES1 further includes an imaging device C1 that captures an image of the user H1 present in the ventilation area R1. The control system CS1 switches the video displayed on the display surface G1 according to the result of analyzing the motion or state of the user H1 from the captured image captured by the imaging device C1. In addition, the control system CS1 controls the air that is blown out from the blower opening 13h toward the blowing area R1 according to the result of analyzing the motion or state of the user H1 from the captured image captured by the imaging device C1.

Below, assuming that the air-conditioned space 9 is a free address working space in an office, the air-conditioning control and video control of the control system CS1 in the air-conditioned space 9 will be described using FIG. In this case, the ventilation area R1 is a space where the user works or takes a break, and office fixtures such as desks and chairs are installed in the ventilation area R1.

The control system CS1 operates in one of the control modes of stages ST1-ST6 in FIG. In the following (11.1) selection stage ST1 and the following (11.2) preparation stage ST2, for example, an arbitrary vacant seat on the office floor is selected and it is possible to sit down and work. The following (11.3) concentration stage ST3, the following (11.4) chat stage ST4, and the following (11.5) creation stage ST5 are intended to enhance the productivity and efficiency of work while, for example, incorporating relaxing scenes. It is something to do. Furthermore, the following (11.6) cleaning stage ST6 is devised to take measures against infectious diseases, for example.

(11.1) Selection stage ST1
When the state of the air blowing area R1 reaches a specific state, the control system CS1 displays, as image control, an image that recommends the use of the air blowing area R1 on the display surface G1.

Specifically, when the cleaning of the blowing area R1 is completed (corresponding to a specific state of the blowing area R1) in the cleaning stage ST6, which will be described later, 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 screen G1 that the user may use the 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" or an image of a color (for example, blue) that allows the user to intuitively recognize that the blowing area R1 is available. is.

In this modified example, the user H1 sits in the blowing area R1 of the blower 1G, which is displayed on the display surface G1 to the effect that it may be used. The user H1 starts work when seated in the ventilation area R1. Therefore, the user H1 can easily recognize the available space and feel a sense of security.

A blower 1G is installed above the user H1 seated in the blowing area R1. Then, the user H1 can adjust the strength and direction of the air blown by the air blower 1G by executing an application pre-installed on the tablet terminal, smartphone, or laptop personal computer that the user H1 carries. Further, the user H1 can switch the image displayed on the display surface G1 of the blower device 1G to his/her favorite image by executing the application. The user H1 can also set the content of the message to be displayed on the display surface G1 of the blower 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 user H1 stays in the air blowing area R1 for a period equal to or longer than the time threshold. When the user H1 stays in the air blowing area R1 for a time equal to or longer than the time threshold, the control system CS1 operating in the preparation stage ST2 performs air blowing control to blow air from the air blowing port 13h of the air blower 1G. to start.

In this modification, the imaging device C1 captures an image of at least part of the air-conditioned space 9 including the blowing area R1, and when the control system CS1 receives the captured image of the imaging device C1, based on the captured image, the control system CS1 Elapsed time after H1 takes a seat in the blowing area R1 is counted. When the elapsed time reaches the time threshold, the control system CS1 controls the blower 1G to blow air from the blower port 13h of the blower 1G.

In the preparation stage ST2, the environment adjustment system ES1 supports the concentration of the user H1, who is about to start work in the ventilation area R1, by creating an air current in the ventilation area R1.

Further, when the control system CS1 detects that the user H1 seated in the blowing area R1 has performed a predetermined specific action (for example, raises one hand) based on the captured image, the control system CS1 turns on the blower 1G. Air blowing control may be performed to start the air blowing operation of the air blower 1G.

In addition, the control system CS1 may use other human detection means such as a pyroelectric sensor that detects the user in the ventilation area R1 to measure the time that the 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. Then, the control system CS1 switches the control mode from the preparation stage ST2 to the concentration stage ST3 when the user H1 is in a specific state. As image control, the control system CS1 operating on the concentration stage ST3 displays an image on the display surface G1 to inform the user that communication with the user H1 is to be terminated.

In order to reduce the risk of infectious diseases these days, people want to avoid direct meetings as much as possible, and more and more people are using so-called web conferences to hold meetings. When you sit on a seat and have a web conference, it tends to be difficult to tell from the side whether you are in a meeting or you can talk to it, and you often talk to it, resulting in a web conference. There is a circumstance that makes it difficult for the people inside. In order to prevent this trouble, it is conceivable to display an intention to refuse to talk on a screen on the ceiling. Therefore, the concentration stage ST3 is an attempt to improve work productivity by preventing being spoken to from the side, which tends to occur during a Web conference.

For example, when the user H1 is in a meeting, the control system CS1 displays on the display surface G1 a video message indicating that communication with the user H1 is to be terminated as video control. At this time, a message such as "I am in a remote meeting. Please do not talk to me." is displayed on the display screen G1.

In addition, 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 the information of the persons who are permitted to enter the air-conditioned space 9, and when the person entering the air-conditioned space 9 is identified, the control system CS1 identifies the tablet carried by the person. It is possible to read the address information of a terminal or an information terminal such as a smart phone. When the control system CS1 detects a person H2 approaching the user H1 based on the captured image, the control system CS1 outputs to the information terminal carried by the person H2 "User H1 is in a remote conference. Do not talk to user H1." Please send a message such as

Therefore, user H1 can concentrate without being disturbed by people 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. Then, the control system CS1 switches the control mode from the concentration stage ST3 to the chat stage ST4 unless the state of the user H1 is a specific state. As image control, the control system CS1 operating in the chat stage ST4 displays an image on the display surface G1 to convey that communication with the user H1 is possible.

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

In addition, 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 the information of the persons who are permitted to enter the air-conditioned space 9, and when the person entering the air-conditioned space 9 is identified, the control system CS1 identifies the tablet carried by the person. It is possible to read the address information of a terminal or an information terminal such as a smart phone. When the control system CS1 detects a person H2 approaching the user H1 based on the captured image, the control system CS1 transmits a message such as "User H1 is available for communication" to the information terminal carried by the 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 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 chat stage ST4 to the creative stage ST5. The control system CS1 operating in the creation stage ST5 displays, as image control, an image having an effect of relaxing the user H1 on the display surface G1.

For example, user H1 may lose his posture and lose himself in thought while looking up at the ceiling. Therefore, when the user H1 continues to look up at the ceiling for a predetermined period of time or longer, the control system CS1 displays an image that relaxes the user H1 on the display surface G1. The video that has the effect of relaxing the user H1 is, for example, an environmental video showing nature such as mountains, forests, forests, the sky, stars, the moon, dusk, sunbeams filtering through foliage, bonfires, or the sea. Also, the image that has the effect of relaxing the user H1 may be a healing image that changes in color, shape, and the like. The user H1 can relax and refresh by looking at the display surface G1.

Also, the control system CS1 operating in the creation stage ST5 preferably varies the amount of air discharged from the blower port 13h of the blower device 1G with 1/f fluctuation. The user H1 can feel the natural wind, relax and refreshed by the air current fluctuating with 1/f fluctuation.

(11.6) Cleaning stage ST6
The control system CS1 operating in the concentration stage ST3, the chat stage ST4, or the creative stage ST5 detects the state or action 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 cleans the blowing area R1 by blowing air from the blowing port 13h of the blower 1G toward the blowing area R1 as blowing control.

The control system CS1 blows air from the blower 1G to the desks and chairs in the blowing area R1 to blow away dust and debris adhering to the desks and chairs. Therefore, when the user H1 leaves the blowing area R1, the control system CS1 can keep the blowing area R1 clean by washing the inside of the blowing area R1 with the airflow.

Also, the blower device 1G preferably includes the discharge device 2 (see FIG. 13) of the first modified example described above. In this case, the blower device 1G can generate active ingredients such as radicals, nanometer-sized charged microparticle water containing radicals, or air ions by the discharge device 2, and add the active ingredients to the air blown into the blowing area R1. can do. As a result, it is also possible to disinfect the desks and chairs in the ventilation area R1.

Also, the control system CS1 operating in the cleaning stage ST6 displays on the display surface G1 that the ventilation area R1 is being cleaned. The image displayed on the display surface G1 in the cleaning stage ST6 is, for example, a color image that allows the user to intuitively recognize that the blowing area R1 cannot be used. In this case, the control system CS1 preferably sets the color of the image to be complementary or opposite to the surrounding color of the display surface G1 as image control while cleaning the air blowing area R1. As a result, the image displayed on the display surface G1 can be made conspicuous, so that the user H1 can easily recognize the space being cleaned and feel a sense of security.

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

(11.7) Flow of Each Stage Basically, the control mode of the control system CS1 transitions in the following order: selection stage ST1→preparation stage ST2→concentration stage ST3→chat stage ST4→creation stage ST5→cleaning stage ST6. , one cycle of the control mode is completed. However, after the preparation stage ST2, transition may be made to any one of the concentration stage ST3, chat stage ST4, and creation stage ST5. Moreover, the number of executions of each of the concentration stage ST3, chat stage ST4, and creation stage ST5 in one cycle is not limited to a specific number of times.

That is, the selection stage ST1 may be entered after the cleaning stage ST6. It is 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 stage described above based on gestures (movements) of the user H1.

Specifically, the control system CS1 determines the gesture made by the user H1 based on the captured image of the imaging device C1. Gestures performed by the user H1 are predetermined in association with the start or end of the stage. Each of the plurality of gestures is a motion distinguishable from each other. For example, the gesture corresponding to the start of the preparation stage ST2 is assumed to be an action of "raising one hand". The gesture corresponding to the start of the creative stage ST5 is assumed to be a motion of "bringing both hands behind the head". The gesture corresponding to the start of the cleaning stage ST6 is assumed to be a motion of "waving one hand".
