(1) Overview Each of the drawings described in the following embodiments is a schematic drawing, and the ratio of the size and the thickness of each constituent element in each drawing does not necessarily reflect the actual dimensional ratio. Not necessarily.

The airflow environment system 1 according to the present embodiment is configured to form an airflow (airflow) in the environmental space 100 (see FIG. 1). As an example of the “environmental space” in the present disclosure, the space in the facility (environmental space 100) is assumed in the present embodiment.

Here, the facility is, for example, an office building, a theater, a movie theater, a public hall, a playground, a complex facility, a restaurant, a department store, a school, a hotel, an inn, a hospital, a nursing home, a kindergarten, a library, a museum, a museum, an underground mall, It may be non-residential such as a station or an airport. The facility may be a house such as a detached house or a condominium (a housing complex) other than a non-house. The “environmental space” in the present disclosure is not limited to the space inside the facility, and may be the space outside the facility (outdoors).

The airflow environment system 1 includes a discharge port 5 and a reflection unit 3. The discharge port 5 discharges the airflow flowing along at least the specific direction A1 to the environmental space 100. The reflector 3 is arranged so as to face the discharge port 5 in the specific direction A1, and is hit by the airflow flowing along the specific direction A1. As an example of the “specific direction” in the present disclosure, the “specific direction A1” of the present embodiment is assumed to be vertically upward. Therefore, the reflection part 3 of the present embodiment is arranged right above the emission port 5. Then, the reflector 3 is configured to recirculate the impinging airflow to the discharge port 5 side in the environmental space 100 (see the recirculation direction A2 in FIG. 1 ).

According to this configuration, the airflow flowing along the specific direction A1 is discharged to the environmental space 100, and in the same environmental space 100, the airflow hitting the reflecting portion 3 is returned to the discharge port 5 side. Therefore, compared with the case where the flow path of the air flow returning to the main body side is separated from the environmental space by the handle as in the air purifying device described in Patent Document 1, a person who is in the environmental space 100 ( It becomes easier for the user) to experience the air flow formed in the environmental space 100. Therefore, it is possible to improve the sensible feeling of the air flow formed in the environmental space 100.

(2) Details Hereinafter, the overall configuration of the airflow environment system 1 according to the present embodiment will be described in detail with reference to FIGS. 1 to 4.

(2.1) Overall Configuration FIG. 1 is an external perspective view of an airflow environment system 1 according to the embodiment. FIG. 2 is a front view of the discharge port 5 in the airflow environment system 1. FIG. 3 is a block diagram showing the configuration of the blower system 2 in the airflow environment system 1.

(2.2) Blower System As shown in FIG. 3, the blower system 2 includes a blower device 4 (fan unit), a light projecting unit E1, a speaker unit F1, a functional unit G1, a control unit H1, an operating unit J1, and a housing. It has 7 mag.

The housing 7 is configured to house or hold therein the blower 4, the light projector E1, the speaker F1, the functional unit G1, the control unit H1, the operation unit J1, and the like. Specifically, as shown in FIG. 1, the housing 7 has a deck 70, a column 71, and a discharge part 72, and is configured to function as a table as a whole. The housing 7 is installed on the floor surface 101 in the environmental space 100.

The deck 70 is formed in a circular plate shape. The deck 70 has a circular hole penetrating in the thickness direction at the center thereof. The pillar 71 is formed in a hollow truncated cone shape. The blower device 4 and the control unit H1 are housed in the column 71. The upper surface of the pillar 71 is open, and the deck 70 is attached to the upper end of the pillar 71 so as to close the opened upper surface of the pillar 71. Further, as shown in FIG. 1, the column 71 has an intake port 6 on its peripheral wall. The intake port 6 is composed of, for example, a plurality of slit-shaped holes that are vertically long. In other words, the airflow environment system 1 includes the air intake port 6 connected to the environment space 100 in the housing 7. The materials for the deck 70 and the columns 71 are not particularly limited, but it is desirable that the housing 7 have dimensions and durability to the extent that they can function as a table. The power cord is exposed from the bottom of the column 71, and the plug of the power cord is connected to, for example, a floor outlet of the floor surface 101 or the like, and the blower device 4, the light projecting unit E1, the speaker unit F1, the functional unit G1, etc. Operating power may be provided to drive the. A caster may be provided on the bottom of the column 71 so that the housing 7 can be easily moved.

The discharge part 72 is formed in a cylindrical shape with both upper and lower ends open. The discharge portion 72 is attached so that the peripheral edge portion of the lower end thereof fits within the edge of the hole in the central portion of the deck 70. The upper surface of the emission portion 72 is covered with a protective cover 73 configured to have a plurality of elongated blades arranged at equal intervals in order to prevent the entry of foreign matter and the like (see FIG. 2). The light projecting portion E1, the speaker portion F1, and the functional portion G1 are housed in the emitting portion 72 or the column 71. The open upper surface of the discharge portion 72 corresponds to the discharge port 5 that discharges the airflow flowing along at least the specific direction A1 to the environment space 100. In other words, the airflow environment system 1 includes the discharge port 5 in the housing 7. The material of the emitting portion 72 is not particularly limited, but since the light emitting portion E1 is housed in the emitting portion 72, it is desirable that the material has high heat dissipation.

An operation unit J1 that receives an operation input from the outside (user) is installed on the deck 70 or the discharge unit 72. The user can turn on and off the power of the blower system 2 by operating the operation unit J1. When the control unit H1 accepts an operation of turning on the power at the operation unit J1, the control unit H1 starts driving the blower device 4. The operation unit J1 may be a remote controller, and in that case, the deck 70 or the emission unit 72 may be provided with a light receiving unit that receives infrared rays emitted from the operation unit J1.

The blower device 4 is configured to generate an air flow that flows along a specific direction A1 (here, vertically upward) by the control of the control unit H1 and send it to the discharge port 5. The blower device 4 is, for example, a sirocco fan that generates an air flow that contains a larger amount of straight-ahead components than swirl components. The air blower 4 sucks in the air in the environment space 100 (the airflow recirculated from the reflection part 3 to the discharge port 5 side as described later) from the intake port 6 and flows along the specific direction A1. Generate. The blower 4 is not limited to a sirocco fan, but may be a propeller fan. The blower device 4 is housed in the support column 71 with its front face facing upward, and is connected to the discharge port 5 via a duct 74 (see FIG. 2) arranged on the front face of the blower device 4. The duct 74 is formed in a cylindrical shape whose upper and lower ends are open. In short, the air flow generated in the air blower 4 and containing a large amount of straight-ahead components can be discharged from the discharge port 5 as it is as an air flow flowing along the specific direction A1 (here, vertically upward).

The air blower 4 may be capable of appropriately changing the air volume by adjusting the rotation speed of the motor by inverter control, for example. For example, the operation unit J1 may be provided with a volume for adjusting the air volume, and the user may be able to appropriately adjust the air volume of the blower 4 in the installation site of the airflow environment system 1, that is, in the environmental space 100. Further, the control unit H1 may automatically and periodically change the air volume of the blower 4.

The control unit H1 has a function of controlling the blower 4. The control unit H1 has, for example, a computer system having a processor and a memory. The computer system functions as the control unit H1 by the processor executing the program stored in the memory. The program executed by the processor is assumed to be recorded in advance in the memory of the computer system here, but may be recorded in a recording medium such as a memory card and provided, or provided through an electric communication line such as the Internet. May be.

At least a part of the functions of the power supply circuit, the lighting circuit, and the control circuit may be integrated in the control unit H1. The operation of the light projecting unit E1 may be controlled to be linked to the operation of the blower device 4 under the control of the control unit H1. The emission color and color temperature of the light source are not particularly limited. Further, the light projecting unit E1 is not limited to general lighting, and may be one that provides effect lighting.

The light source of the light projecting section E1 is housed in the emitting section 72 so as to face the window section 730 (see FIG. 2) of the protective cover 73, and the light emitted from the light source of the light projecting section E1 passes through the window section 730. Then, the light is irradiated toward the reflecting portion 3. That is, the light of the light projecting portion E1 can be emitted upward from the emission port 5 in the present embodiment, similarly to the air flow. Lighting, dimming, and extinguishing of the light projecting unit E1 can be performed by operating the operation unit J1, for example. By providing the light projecting unit E1, light (brightness) can be provided to the environment space 100 in addition to the airflow.

The speaker unit F1 is configured to emit a sound such as music toward the reflecting unit 3 side. The speaker unit F1 includes a speaker F10 (see FIG. 2), a power supply circuit, an acoustic circuit, a control circuit, and the like. At least a part of the functions of the power supply circuit, the acoustic circuit, and the control circuit may be integrated in the control unit H1. The operation of the speaker unit F1 may be controlled to be linked to the operation of the blower device 4 under the control of the control unit H1. The speaker F10 is arranged to face the protective cover 73 with the front surface thereof facing upward. Therefore, the sound output from the speaker F10 can be emitted upward in the present embodiment from the emission port 5 similarly to the airflow.

Here, as an example, the speaker unit F1 is assumed to be a so-called parametric speaker in which ultrasonic waves are used to provide directivity. A part of the sound output from the speaker unit F1 may be reflected by the reflecting unit 3. Since the speaker unit F1 is a parametric speaker, a sound is provided to the person in the environment space 100, particularly under a specific narrow range such as directly below the reflection unit 3. Turning on and off the power of the speaker unit F1 and adjusting the volume can be performed by operating the operation unit J1, for example. Since the speaker unit F1 is provided, sound (sound) can be provided to the environment space 100 in addition to the airflow.

The functional unit G1 is configured to add an additional element to the airflow discharged from the discharge port 5 to the environmental space 100. The additional element includes at least one of scent, air purification, and temperature change.

When the additional element includes a scent, the functional unit G1 has, for example, a scent presenting device including a fragrance. The scent presenting device is housed in the emission section 72. The scent vaporized from the fragrance can be mixed with the air flow from the blower 4 through the duct 74. As a result, the airflow environment system 1 can provide the person (user) in the environment space 100 with the air of good scent.

When the additional element includes air cleaning, the functional unit G1 has, for example, an air cleaning device. The air cleaning device is housed in the column 71. The air purifying device has a dust collecting filter for collecting fine particles such as pollen in the air sucked in through the intake port 6 and a deodorizing filter. The air purified by the air cleaning device can be discharged upward from the discharge port 5 in the present embodiment as an air flow from the blower device 4. As a result, the airflow environment system 1 can provide the person (user) in the environment space 100 with purified air.

When the additional element includes air purification, the functional unit G1 may have, for example, a space disinfection deodorizer. The space disinfection deodorizer is housed in the column 71. The space disinfection deodorizer is configured to generate hypochlorous acid and mix it with the air flow generated by the blower 4. The air flow containing hypochlorous acid is discharged upward from the discharge port 5 in the present embodiment to sterilize the environmental space 100. As a result, the airflow environment system 1 can provide the person (user) in the environment space 100 with purified air.

When the additional element includes a temperature change, the functional unit G1 has, for example, an air conditioner. The air conditioner has a compressor, and cool air or warm air generated in the air conditioner can be discharged upward in the present embodiment from the discharge port 5 as an air flow from the blower 4. As a result, the airflow environment system 1 can provide the person (user) in the environment space 100 with air at a comfortable temperature.

When the functional unit G1 includes the air cleaning device, the space disinfection deodorizer, and the air conditioner described above, turning on/off of the power supplies and adjustment of various parameters can be performed by, for example, operating the operation unit J1. Is. It should be noted that the control unit H1 may centrally control the functional unit G1. The operation of the functional unit G1 may be controlled to be linked to the operation of the blower device 4 under the control of the control unit H1.

As described above, the airflow environment system 1 can add an additional element to the airflow by providing the functional unit G1.

(2.3) Reflector The reflector 3 is arranged so as to face the emission port 5 in the specific direction A1. The reflector 3 is configured so that the airflow emitted from the outlet 5 and flowing along the specific direction A1 hits. Further, the reflecting portion 3 is configured to cause the hit airflow to recirculate to the discharge port 5 side in the environmental space 100.

The configuration of the reflector 3 will be described in detail below. As shown in FIG. 1, the reflection section 3 has a main body section 30, a support section 33, and a mounting section 35.

The main body 30 is formed into a substantially umbrella shape (more specifically, a curved bowl shape) with an open lower surface. As an example, it is assumed that the main body 30 is composed of a cloth and a plurality of bones that maintain the cloth in an umbrella shape, but the main body 30 is not particularly limited and may have another structure. That is, the main body 30 may be a synthetic resin molded product or a metal molded product. It should be noted that the body portion 30 is preferably made of a material that takes into account the acoustic characteristics of the sound output from the speaker portion F1. For example, when enhancing the acoustic effect, a material having low sound absorption is used.

The main body 30 has an inner curved surface 300 facing the discharge port 5, as shown in FIG. The curved surface 300 is inclined such that the tangential direction D at the opening edge thereof is wider with respect to the vertical direction toward the lower side. Further, the main body portion 30 has a first region 31 and a second region 32 on the curved surface 300. The first area 31 is a central area including the apexes of the curved surface 300, and is an area to which the air flow flowing along the specific direction A1 hits. The second region 32 is around the first region 31. In other words, when the curved surface 300 is viewed from the front (from the lower side), the second region 32 is a donut-shaped region. The second region 32 is a region in which the air flow hitting the first region 31 flows along and is returned to the discharge port 5 side. In the main body portion 30 of the present embodiment, the second region 32 approaches the discharge port 5 side as the distance from the first region 31 increases in the direction orthogonal to the specific direction A1 (horizontal direction in the present embodiment). Is curved. The color of the curved surface 300 is not particularly limited, but a color considering the reflection characteristic of the light emitted from the light projecting portion E1 is desirable.

As shown in FIG. 1, the support portion 33 is a portion for suspending the main body portion 30 from the ceiling surface side. In the present embodiment, the support portion 33 is formed in a vertically long rod shape, but the support portion 33 may be formed in a string shape. A mounting portion 35 is provided at a first end (upper end in FIG. 1) of the support portion 33, and a second end (lower end in FIG. 1) of the support portion 33 is attached to an outer apex of the main body portion 30. ..

The attachment portion 35 is configured to be detachably attached to the wiring duct 200. The wiring duct 200 is formed in a rail shape and is fixed to the ceiling or the like of the facility. The wiring duct 200 may be, for example, a duct rail for lighting. The wiring duct 200 includes a duct body having a so-called lip groove. The mounting portion 35 has, for example, a terminal plate protruding in a T shape. After the terminal plate is inserted into the lip groove of the wiring duct 200, the mounting portion 35 is rotated about 90 degrees about the axis of the mounting portion 35 so that the terminal plate is locked in the lip groove, and the mounting portion 35 is attached to the wiring duct 200. Will be stopped. By providing the attachment portion 35, the workability regarding the installation of the reflection portion 3 is improved.

As described above, according to the airflow environment system 1 of the present embodiment, the reflector 3 is configured to cause the hit airflow to flow back to the discharge port 5 side in the environment space 100. Therefore, it is possible to improve the sensation of the airflow formed in the environmental space 100 to the user (person) who is in the environmental space 100. In addition, since the reflecting portion 3 has the first region 31 and the second region 32, a layer of the air flow recirculated to the discharge port 5 side around the first region 31 is easily formed, and The layers increase the likelihood that the environmental space 100 will be divided into two spaces. Therefore, the sensation of the airflow to the user (person) in the environment space 100 is further improved.

By the way, the airflow environment system 1 may further include an illumination unit E2 that emits light toward the discharge port 5 side, as shown in FIG. The illuminating section E2 is arranged in the first region 31 of the main body section 30 in the reflecting section 3. The illumination unit E2 includes, for example, one or a plurality of LEDs as a light source. The illumination unit E2 includes a translucent cover that covers the light source, a power supply circuit, a lighting circuit, a control circuit, and the like. Lighting, dimming, and extinguishing of the illumination unit E2 can be performed by, for example, an operation unit (not shown) provided in the illumination unit E2. The emission color and color temperature of the light source are not particularly limited. The illumination unit E2 is not limited to general illumination, and may be one that provides presentation illumination.

The operating power of the lighting unit E2 may be supplied from the wiring duct 200. The terminal plate of the attachment portion 35 may be engaged with the lip groove of the wiring duct 200 to achieve electrical connection with the conductor portion of the wiring duct 200. A power cord may be housed in the support portion 33, and the terminal plate of the mounting portion 35 may be electrically connected to the power circuit of the lighting unit E2 via the power cord. The power supply circuit of the lighting section E2 receives, for example, commercial AC power from the conductor section of the wiring duct 200 via the power cord in the support section 33 and the terminal plate of the mounting section 35, and converts it into DC power for LED lighting. You may. The airflow environment system 1 can provide the environment space 100 with light (brightness) in addition to the airflow because the illumination unit E2 is provided.

(2.4) Airflow in Environmental Space Hereinafter, the airflow that can be formed in the environmental space 100 by the airflow environmental system 1 will be described with reference to FIG.

FIG. 4 shows an air flow discharged from the discharge port 5 in the air flow environment system 1 and a state in which the air flow hits the reflecting portion 3 and the hit air flow recirculates to the discharge port 5 side in the environmental space 100 (flow. (Line) shows the simulation results. The airflow environment system 1 of FIG. 4 is slightly different from the airflow environment system 1 of FIG. 1, and the housing 7 and the support portion 33 are omitted and illustrated. In addition, the emission port 5 of FIG. 4 is located at a position slightly higher than the emission port 5 of FIG. 1 (position closer to the reflecting portion 3).

By operating the airflow environment system 1, as shown in FIG. 4, a first flow path P1 and a second flow path P2 are formed in the environmental space 100. The first flow path P1 is a flow path through which the air flow discharged from the discharge port 5 flows toward the reflecting section 3, and the second flow path P2 is the side where the air flow hitting the reflecting section 3 is on the discharge port 5 side. It is a flow path that returns to.

That is, the airflow discharged from the discharge port 5 flows toward the first region 31 of the reflecting portion 3 through the first flow path P1. Then, the airflow that hits the first region 31 of the reflecting portion 3 and spreads outward along the second region 32 of the reflecting portion 3 flows back to the discharge port 5 side (vertically downward) through the second flow path P2. When viewed along the specific direction A1 (in this embodiment, for example, from above), the second flow path P2 is formed so as to surround the first flow path P1.

Therefore, for example, a person (user) who approaches the first flow path P1 side from the outside of the air flow environment system 1 is likely to come into contact with the layer of the air flow recirculating through the second flow path P2. Therefore, the sensation of airflow is further improved. In particular, since the velocity of the air flow that recirculates through the second flow path P2 is attenuated by the reflecting portion 3, it can be lower than the velocity of the air flow discharged from the discharge port 5. Therefore, conversely, as compared with the case where the airflow discharged from the discharge port 5 is directed toward the reflecting portion 3 through the second flow path P2 and is returned to the discharge port 5 side through the first flow path P1. It is possible to reduce the possibility of giving discomfort to a person (user) approaching the first flow path P1.

Further, in the present embodiment, the emission port 5 and the reflecting portion 3 are separated from each other in the specific direction A1 via the hollow portion 9 of the void. The air flow discharged from the discharge port 5 (forward air flow) and the air flow returning to the discharge port 5 side (return air flow) flow through the hollow portion 9. In other words, there is no obstacle (wall or the like) that separates the first flow path P1 and the second flow path P2 from the discharge port 5 to the reflection section 3. Therefore, it is possible to increase the possibility of giving a feeling of openness to a person (user) in the environmental space 100.

Further, in the present embodiment, the blower device 4 sucks the airflow recirculated from the reflecting portion 3 to the discharge port 5 side from the intake port 6 and generates the airflow flowing along the specific direction A1. The airflow formed in the space 100 can be circulated more stably. In particular, since the intake port 6 is arranged at a position lower than the discharge port 5, the second flow path P2 can be formed as a flow path having a relatively long distance in the vertical direction.

By the way, in the present embodiment, the second region 32 of the reflecting section 3 is formed between the first flow path P1 and the second flow path P2 so that the intermediate layer X1 having a relatively low airflow velocity is formed. Shape, or the distance from the emission port 5 to the first region 31 of the reflecting portion 3 and the like are defined. A user who uses the airflow environment system 1 can experience the presence of the intermediate layer X1 separated by the airflow by entering the intermediate layer X1 from the outside of the airflow environment system 1 after passing through the second flow path P2. .. The middle layer X1 is provided as if it is an environment that is shielded from the outside, even though it is not partitioned by a physical partition wall. The user can experience the middle layer X1 with a gentle airflow as a place for relaxation. Further, it is possible to reduce the cost as compared with the case of being partitioned by a physical partition wall, and the user can easily enter the middle layer X1 and the convenience is high.

Further, in the airflow environment system 1 of the present embodiment, when the airflow discharged from the discharge port 5 hits the reflecting portion 3 and then flows back to the discharge port 5 side (vertically downward) through the second flow path P2, A part of the air flow is sucked through the intake port 6 and can be circulated as a whole. Therefore, it can be expected that the usage amount of the additional element in the functional unit G1 will be reduced.

When the additional element includes air purification, there is a high possibility that the air purified by the air cleaning device of the functional unit G1 will be discharged from the discharge port 5 and then recirculated and sucked again from the intake port 6. As a result, the airflow environment system 1 contributes to prolonging the life of the dust collecting filter, the deodorizing filter, and the like.

When the additional element includes a temperature change, cold air (or warm air) generated by the air conditioner included in the functional unit G1 may be discharged from the discharge port 5 and then recirculated and sucked again from the intake port 6. Becomes higher. As a result, the airflow environment system 1 contributes to prolonging the life of the air conditioner and reducing the power consumption of the air conditioner.

Further, in the airflow environment system 1 of the present embodiment, when the airflow discharged from the discharge port 5 hits the reflecting portion 3 and then flows back to the discharge port 5 side (vertically downward) through the second flow path P2, The air flow can function as an air curtain. In particular, the recirculating airflow can be discharged in a form that does not easily mix with the airflow in the space inside the air curtain. As a result, the airflow environment system 1 can confine, for example, an additional element by the functional unit G1 included in the airflow discharged from the discharge port 5 by the air curtain. Therefore, it can be expected that the additional element is suppressed from leaking to the outside of the air curtain. In short, according to the airflow environment system 1, the situation in which the space inside the air curtain is filled with additional elements is likely to be maintained.

(3) Modifications The above embodiment is only one of various embodiments of the airflow environment system according to the present disclosure. The above-described embodiment can be variously modified according to the design and the like as long as the object of the airflow environment system according to the present disclosure can be achieved. Hereinafter, modified examples of the above embodiment will be listed. The modifications described below can be applied in appropriate combination. Hereinafter, the above embodiment may be referred to as a “basic example”.

(3.1) Modification 1
Hereinafter, the airflow environment system 1A of the modification 1 will be described with reference to FIG. However, constituent elements that are substantially common to the airflow environment system 1 of the basic example are designated by the same reference numerals, and description thereof will be appropriately omitted.

As a result of earnest verification, the inventors of the present disclosure have determined that the shape of the reflection part 3 is more than the height position of the discharge port 5 (distance from the discharge port 5 to the reflection part 3), the air volume and the wind speed of the blower 4. It has been found that this is a factor that can greatly influence the formation of the air flow returning to the side of the discharge port 5.

FIG. 5 is a schematic diagram for explaining an airflow formed by the airflow environment system 1A according to the first modification. As shown in FIG. 5, the airflow environment system 1A of the modified example 1 is provided with a reflection portion 3A having a shape different from that of the reflection portion 3 of the basic example, instead of the reflection portion 3 of the basic example. Different from the system 1. The discharge port 5 in FIG. 5 is at substantially the same height as the discharge port 5 in FIG. 1 in the basic example.

The reflecting section 3A of the first modification includes a main body section 30A, a supporting section 33, and a mounting section 35 (the supporting section 33 and the mounting section 35 are not shown in FIG. 5). 30 A of main-body parts are formed in the substantially umbrella shape which the lower surface opened. However, the main body 30 of the basic example has the curved surface 300 curved in a bowl shape, while the main body 30A of the modified example 1 has the flat conical curved surface 300A. That is, the curved surface 300A is a conical surface.

As shown in FIG. 5, the main body 30A has a first region 31A and a second region 32A on the inner curved surface 300A facing the discharge port 5. The first area 31A is a central area including the apex of the curved surface 300A, and is an area to which the airflow flowing along the specific direction A1 hits. The second area 32A is around the first area 31A. The second region 32A is a region in which the airflow hitting the first region 31A flows along and is returned to the discharge port 5 side. In the main body portion 30A of the present embodiment, the second region 32A is straightly inclined so as to come closer to the discharge port 5 as it goes away from the first region 31A along the horizontal direction.

FIG. 5 shows an airflow emitted from the outlet 5 in the airflow environment system 1A of the modified example 1, and the airflow hits the reflecting portion 3A, and the hit airflow is returned to the outlet 5 side in the environmental space 100. The result of the simulation (streamline) is shown.

By operating the airflow environment system 1A, as shown in FIG. 5, a first flow path P1A and a second flow path P2A are formed in the environmental space 100. That is, the airflow discharged from the discharge port 5 flows toward the first region 31A of the reflecting portion 3A through the first flow path P1A. Then, the airflow that hits the first area 31A of the reflecting section 3A and spreads outward along the second area 32A of the reflecting section 3A flows back to the discharge port 5 side (vertically downward) through the second flow path P2A.

Here, unlike the second flow path P2 of the basic example, the second flow path P2A of the modified example 1 is diffused in a direction away from the blower system 2. Therefore, in the modified example 1, the volume of the intermediate layer X1A can be ensured to be larger than that in the basic example. As a result, it is highly possible that more users can use the intermediate layer X1A. However, in terms of "circulation" in which the airflow discharged from the discharge port 5 returns to the intake port 6 again, the modified example 1 may have a lower circulation property than the basic example. As in the basic example, when the second region 32 is curved so as to be closer to the discharge port 5 side as it is farther from the first region 31, a layer of the air flow recirculated to the discharge port 5 side is further formed. It is easy to be done. Therefore, the user who uses the airflow environment system 1A has a higher sensation of airflow in the basic example than in the first modification.

Next, another example of Modified Example 1 (airflow environment system 1B) will be described with reference to FIG.

FIG. 6 is a schematic diagram for explaining an airflow formed by the airflow environment system 1B according to another example of the first modification. As shown in FIG. 6, the airflow environment system 1B includes a reflecting section 3B instead of the reflecting section 3 of the basic example. The body portion 30B of the reflecting portion 3B has a curved surface 300B (having a first region 31B and a second region 32B) that is curved like a bowl, similarly to the reflecting portion 3 of the basic example. However, the curved surface 300B differs from the curved surface 300 of the basic example in that the tangential direction D1 at the opening edge is substantially parallel to the vertical direction. That is, the tangential direction D at the opening edge of the curved surface 300 of the basic example is inclined so as to expand outward as it goes downward with respect to the vertical direction.

The reflector 3B in FIG. 6 has higher circulation than the basic example and the example in FIG. Therefore, a layer of the air flow recirculated to the discharge port 5 side is more likely to be formed, and the sensation of the air flow to the person (user) in the environment space 100 can be improved. However, the volume of the intermediate layer X1B formed between the first flow path P1B and the second flow path P2B tends to be small, and the possibility that the user can experience the existence of the intermediate layer X1B separated by the airflow is reduced. To do. The volume of the intermediate layer X1B can be increased by increasing the air volume of the blower device 4 or adjusting the height position of the discharge port 5.

Next, another example of the modified example 1 (airflow environment system 1C) will be described with reference to FIG. 7.

FIG. 7 is a schematic diagram for explaining an airflow formed by the airflow environment system 1C according to another example of the first modification. As shown in FIG. 7, the airflow environment system 1C includes a reflecting portion 3C instead of the reflecting portion 3 of the basic example. The body portion 30C of the reflecting portion 3C has a curved surface 300C (having a first region 31C and a second region 32C) that is curved like a bowl, similarly to the reflecting portion 3 of the basic example. However, this curved surface 300C differs from the curved surface 300 of the basic example in that the tangential direction D2 at the opening edge is inclined so as to narrow inward as it goes downward.

The reflector 3C in FIG. 7 has a higher circulation property than the example in FIG. Therefore, a layer of the air flow recirculated to the discharge port 5 side is more likely to be formed, and the sensation of the air flow to the person (user) in the environment space 100 can be further improved. However, the volume of the intermediate layer X1C formed between the first flow path P1C and the second flow path P2C is likely to be further reduced. The volume of the intermediate layer X1C can be increased by increasing the air volume of the blower device 4 or adjusting the height position of the discharge port 5.

Further, another example of Modified Example 1 (airflow environment system 1D) will be described with reference to FIG.

FIG. 8 is a schematic diagram for explaining an airflow formed by the airflow environment system 1D according to yet another example of the first modification. As shown in FIG. 8, the airflow environment system 1D includes a reflecting section 3D instead of the reflecting section 3 of the basic example. The body portion 30D of the reflecting portion 3D has a curved surface 300D (having a first region 31D and a second region 32D) curved in a bowl shape, like the reflecting portion 3 of the basic example. However, the curved surface 300D is different from the curved surface 300 of the basic example in that the distance (depth W1) from the opening surface of the curved surface to the apex is deeper than the depth of the curved surface 300 of the basic example. The tangential direction D3 at the opening edge of the curved surface 300D is substantially parallel to the vertical direction.

Circularity is also relatively high in the reflection part 3D in FIG. Therefore, a layer of the air flow recirculated to the discharge port 5 side is more likely to be formed, and the sensation of the air flow to the person (user) in the environment space 100 can be improved. However, the volume of the intermediate layer X1D formed between the first flow path P1D and the second flow path P2D tends to be small. It is possible to increase the volume of the intermediate layer X1D by increasing the air volume of the blower device 4 or adjusting the height position of the discharge port 5.

(3.2) Modification 2
Hereinafter, the airflow environment system 1E of the modified example 2 will be described with reference to FIG. However, constituent elements that are substantially common to the airflow environment system 1 of the basic example are designated by the same reference numerals, and description thereof will be appropriately omitted.

FIG. 9 is an external perspective view of an airflow environment system 1E according to Modification 2. In the airflow environment system 1 of the basic example, the discharge port 5 is provided in the housing 7 configured to also function as a table. On the other hand, the airflow environment system 1E of the modified example 2 is different from the airflow environment system 1 of the basic example in that the discharge port 5 is directly provided on the floor surface 101.

In addition, in the airflow environment system 1 of the basic example, the reflector 3 has a hanging structure. On the other hand, the airflow environment system 1E of the modified example 2 is different from the airflow environment system 1 of the basic example in that the airflow environment system 1E of the modified example 2 includes the reflecting portion 3E having an embedded structure.

Here, the discharge port 5 of Modification 2 is configured, for example, as a circular through hole that penetrates the floor material in the thickness direction. In this case, the blower device 4, the light projecting unit E1, the speaker unit F1, the functional unit G1, the control unit H1, and the like are installed under the floor. The operation unit J1 may be installed near the discharge port 5 or may be installed on the wall surface 152.

FIG. 9 shows an example in which the reflection section 3E of the second modification is embedded and arranged in one of a plurality of square type ceiling materials 151 in the system ceiling 150. The reflecting portion 3E is not limited to the case where it is embedded in one ceiling material 151, and may be embedded over a plurality (for example, four) of ceiling materials 151. The reflection part 3E is directly fixed to, for example, a hanging bolt of a ceiling slab in the ceiling.

According to the second modification, the convenience can be improved while reducing the possibility that the aesthetic appearance of the environmental space 100 is impaired, as compared with the case where the discharge port 5 is arranged on one surface of a dedicated housing, for example. .. Moreover, the airflow environment system 1E of the second modification can share the components (floor and housing).

As another example of Modification 2, the ceiling material 151 itself may be the reflecting portion 3E having the curved surface 300 recessed in an umbrella shape.

As yet another example of Modification 2, the airflow environment system 1E may include a plurality of pairs of one reflecting portion 3E and one outlet 5 corresponding to each other. Specifically, the plurality of reflecting portions 3E may be embedded in the system ceiling 150, and the plurality of outlets 5 may be provided on the floor surface 101 so as to correspond to the respective reflecting portions 3E in a one-to-one manner. .. In this case, the numbers of the blowers 4 and the control units H1 do not necessarily have to be the same as the numbers of the discharge ports 5. For example, the airflow generated by one blower device 4 may be discharged from a plurality of discharge ports 5 through a duct installed under the floor. Further, one control unit H1 may be installed in a management room or the like in the facility so that the plurality of blowers 4 can be collectively centrally managed. Note that, similarly in the basic example, the airflow environment system 1 includes one reflecting unit 3 and one discharge port 5 as a set, and includes a plurality of these units, and one control unit H1 causes a plurality of blowers. 4 may be configured to be collectively managed collectively.

(3.3) Modification 3
Hereinafter, the airflow environment system 1F of Modification 3 will be described with reference to FIG. However, constituent elements that are substantially common to the airflow environment system 1 of the basic example are designated by the same reference numerals, and description thereof will be appropriately omitted.

FIG. 10 is an external perspective view of an airflow environment system 1F according to Modification 3. The airflow environment system 1F of Modification 3 has a structure in consideration of convenience and design, assuming that it will be installed in a hotel lobby or the like. The housing 7F of the air blowing system of the airflow environment system 1F is configured to also function as a long table. Further, the housing 7F has a bottle-shaped figurine 75, and the open upper surface thereof serves as the discharge port 5. The figurine 75 has an opening at the bottom, and the airflow of the blower 4 housed in the long table can be discharged upward from the discharge port 5 through the opening of the figurine 75. A plurality of lobby sofas 301 are installed so as to surround the housing 7F.

If the number of the lobby sofas 301 is one (on the left side of FIG. 10), the housing 7K may be provided instead of the housing 7F. The housing 7K is configured to function as a side table, and its configuration is similar to that of the housing 7F. That is, the casing 7K has a bottle-shaped figurine 75, and the open upper surface thereof serves as the discharge port 5.

Here, the reflection section 3F of Modification 3 has a cylindrical main body section 30F whose lower surface is open. The reflecting portion 3F does not have the supporting portion 33 of the basic example, and the main body portion 30F is directly attached to the ceiling surface. The lobby sofa 301 is arranged so as to be substantially within the projection area when the opening surface of the main body portion 30F is projected onto the floor surface 101. Therefore, the reflecting portions 3F having various sizes and shapes are installed according to the number and shape of the lobby sofas 301.

In this way, by providing the airflow by the airflow environment system 1F in the hotel lobby or the like, it is possible to provide a local space different from the surroundings in the environment space 100 without being blocked by a physical partition wall. .. Furthermore, the airflow environment system 1F can provide a local space that is a more comfortable place of relaxation in the environmental space 100 by appropriately combining light, sound, and additional elements (fragrance, etc.) with the provided airflow. ..

Next, another example of Modified Example 3 (airflow environment system 1G) will be described with reference to FIG.

FIG. 11 is an external perspective view of an airflow environment system 1G according to another example of Modification Example 3. The airflow environment system 1G of FIG. 11 has a structure in consideration of convenience and sterilization, assuming that it will be installed in a waiting room or the like in a hospital. The airflow system of the airflow environment system 1G has a pole-shaped housing 7G. The discharge port 5 is formed on the upper surface of the housing 7G. The airflow of the blower device 4 housed in the housing 7G can be discharged upward from the discharge port 5. Further, a donut-shaped waiting chair 302 is arranged so as to surround the periphery of the housing 7G.

The reflecting portion 3G in FIG. 11 has an umbrella-shaped main body portion 30G whose lower surface is open. Like the lobby sofa 301 in FIG. 10, the waiting chair 302 is arranged so as to be substantially within the projection area of the opening surface of the main body portion 30G. The reflector 3G in FIG. 11 has a relatively large size so that it can be used by as many users (patients) as possible.

As described above, by providing the airflow by the airflow environment system 1G in the waiting room or the like in the hospital, it is possible to realize the provision of a local space different from the surroundings in the environmental space 100 without being blocked by a physical partition wall. .. In addition, the air flow passing through the second flow path has an effect as a barrier function, and the risk of nosocomial infection can be reduced. Furthermore, the airflow environment system 1G can provide a local space that becomes a cleaner place in the environmental space 100 by appropriately combining an additional element (air purification: hypochlorous acid, etc.) with the provided airflow. ..

(3.4) Modification 4
Hereinafter, the airflow environment system 1H of the modified example 4 will be described with reference to FIG. However, constituent elements that are substantially common to the airflow environment system 1 of the basic example are designated by the same reference numerals, and description thereof will be appropriately omitted.

FIG. 12 is an external perspective view of an airflow environment system 1H according to Modification 4. The airflow environment system 1H of the modified example 4 is different from the airflow environment system 1 of the basic example in that the discharge port 5 is arranged on one surface of a member forming the chair 303. The reflection part 3 of the airflow environment system 1H is common to the basic example, and therefore illustration and description thereof are omitted.

The airflow environment system 1H of Modification 4 has a housing 7H that functions as a chair 303. The housing 7H includes a hollow seat portion 76 having a substantially rectangular parallelepiped shape, and a prismatic backrest 77 provided at the center of an upper surface (seat surface 760) of the seat portion 76. The blower 4 and the like are housed in the seat portion 76 or the backrest 77.

The outlet 5 is provided on the upper end surface of the backrest 77. The intake port 6 is provided on the seat surface 760 of the seat portion 76. Specifically, the seat surface 760 is assembled so that, for example, a plurality of square members 761 are arranged side by side with a predetermined gap, and the gap between the adjacent square members 761 becomes the intake port 6.

The airflow environment system 1H according to the modified example 4 is more convenient than the case where the discharge port 5 is arranged on one surface of a dedicated housing, for example, while reducing the possibility that the aesthetic appearance of the environment space 100 is impaired. Can be improved. Moreover, the airflow environment system 1H of the modified example 4 can share the components (chair and housing).

(3.5) Modification 5
Hereinafter, the airflow environment system 1I of the fifth modification will be described with reference to FIG. However, constituent elements that are substantially common to the airflow environment system 1 of the basic example are designated by the same reference numerals, and description thereof will be appropriately omitted.

The airflow environment system 1I of the modified example 5 is different from the airflow environment system 1 of the basic example in that a guide portion 8 is further provided.

FIG. 13 is an external perspective view of the airflow environment system 1I of Modification 5. It is assumed that the airflow environment system 1I of Modification 5 is installed, for example, in a lobby of a hotel, a hospital, a station, or a waiting room such as an airport.

The reflector 3H has a main body 30 and a support 33H. In FIG. 13, the main body portion 30 of the reflecting portion 3H is shown only by the alternate long and short dash line. The body portion 30 of the reflecting portion 3H has a substantially umbrella shape with an open lower surface, and is substantially common to the body portion 30 of the reflecting portion 3 of the basic example.

Unlike the supporting portion 33 of the reflecting portion 3 of the basic example, the supporting portion 33H of the reflecting portion 3H is not a portion for suspending the main body portion 30 from the ceiling surface side, but protrudes from the pedestal B1 to support the main body portion 30. ing. That is, the support portion 33H of the reflection portion 3H is a portion corresponding to the handle portion (axis) of the umbrella (main body portion 30). The first end (upper end) of the support portion 33H is attached to the apex inside the main body portion 30, and the second end (lower end) of the support portion 33H is fixed to the pedestal B1. However, here, the support portion 33H of the reflection portion 3H is realized by the guide portion 8. In other words, the guide portion 8 supports (the body portion 30 of) the reflecting portion 3H.

The housing 7I of the airflow environment system 1I also serves as a pedestal B1 on which a plurality of people can sit. That is, the airflow environment system 1I includes the pedestal B1. The pedestal B1 has a flat cylindrical shape in the specific direction A1. The pedestal B1 functions as a chair on which a person can sit. The central axis of the pedestal B1 substantially coincides with the central axis of the support portion 33H corresponding to the handle portion of the umbrella (main body portion 30). The blower 4 and the like are housed in the pedestal B1 (housing 7I). The intake ports 6 are arranged on the outer peripheral surface of the pedestal B1 (two positions are shown in FIG. 13). Here, the outer diameter of the main body portion 30 of the umbrella-shaped reflecting portion 3H is set to be larger than the outer diameter of the pedestal B1. The fact that the outer diameter of the main body portion 30 is larger than the outer diameter of the pedestal B1 makes it easier to recirculate the air flow hitting the reflecting portion 3H.

The guide unit 8 is configured to guide the air flow discharged from the discharge port 5 so as to flow toward the reflecting unit 3H side along the specific direction A1. The lower end of the guide portion 8 is fixed to the pedestal B1. The guide portion 8 has one or a plurality of partition portions 80 that divide the environment space 100 into two or more along a direction D4 orthogonal to the specific direction A1. Here, as an example, the partition 80 has a total of four (only three are shown in FIG. 13), and the environment space 100 is divided into four. Each partition 80 has a plate-like shape elongated along a specific direction A1. Here, the four plate-shaped partition parts 80 guide the airflow discharged from the discharge port 5 so as to flow toward the reflection part 3H along the specific direction A1.

The four partition parts 80 project from the pedestal B1 along the specific direction A1. Here, the four partition portions 80 are arranged so as to divide the region of the upper surface of the pedestal B1 into four equal parts with the central axis of the pedestal B1 as the center when the pedestal B1 is viewed from above. That is, each of the quadrants of the upper surface of the pedestal B1 has a fan shape with a central angle of about 90 degrees. Here, as an example, the dimensions of the pedestal B1 are set so that one person can sit in each fan-shaped region. That is, here, it is set that four people can sit on the pedestal B1 at the same time. However, the number of people who can sit at the same time is not limited to four.

The outer edge (edge on the side opposite to the central axis) of each partition 80 has an intermediate edge 800 extending in the vertical direction, a first edge 801 continuous from the lower portion of the intermediate edge 800, and an intermediate edge 800. It is composed of a second edge 802 continuous from the upper part and a third edge 803 continuous from the tip of the second edge 802. The first edge 801 is curved so as to expand toward the peripheral edge of the pedestal B1 as it approaches the upper surface of the pedestal B1. The second edge 802 is curved so as to be convex upward. The third edge 803 is curved so as to hang down along the inner surface of the reflecting portion 3H. The four partition portions 80 function as a plurality of bone portions that stably hold the umbrella-shaped reflecting portion 3H by contacting the inner surface of the reflecting portion 3H at each third edge 803.

Further, the guide portion 8 further has a backrest portion 81 projecting from the upper surface of the pedestal B1 along the specific direction A1 between two adjacent partition portions 80 of the four partition portions 80. A total of four backrests 81 are provided so as to be arranged in each fan-shaped region of the pedestal B1 (only two are shown in FIG. 13). A person seated in each fan-shaped region of the pedestal B1 can relax using the backrest 81.

By the way, each backrest 81 has a hollow cylindrical shape with both longitudinal end faces open. Furthermore, each backrest portion 81 communicates with the accommodation space of the blower 4 in the pedestal B1. The open upper surface of each backrest portion 81 serves as the discharge port 5. In short, the airflow of the blower 4 in the pedestal B1 can pass through the respective backrests 81 and be discharged upward from the discharge port 5. Therefore, the airflow of the blower device 4 is individually discharged upward from the discharge ports 5 at four places in total. Here, the common air flow from one blower device 4 branches at the entrances of the four backrests 81 and is discharged from the four discharge ports 5.

The airflow environment system 1I of the fifth modification can further improve the stability of the recirculating airflow by including the guide portion 8.

Further, since the guide portion 8 has the partition portion 80, it is possible to individually improve the sensation of air flow in each of the plurality of spaces divided by the partition portion 80. Further, since the partition 80 projects from the pedestal B1 along the specific direction A1, each person can sit on the pedestal B1 and experience the airflow in each space divided by the partition 80. Further, since the guide portion 8 supports the reflection portion 3H, it is not necessary to provide a support member for supporting the reflection portion 3H separately from the guide portion 8 that guides the air flow.

In addition, in the airflow environment system 1I of Modification Example 5, each person sits on the upper surface of the pedestal B1 in a region between two adjacent partitioning portions 80, whereby a space surrounded by the two partitioning portions 80 is formed. Inside, the airflow emitted from the corresponding outlet 5 can be experienced. In particular, by being partitioned by the partition section 80, a certain distance from a person who is seated sideways is maintained, and there is a high possibility of blocking the line of sight of a person who is sitting sideways. As a result, it is possible to give a sense of security to each person who uses the airflow environment system 1I.

The airflow environment system 1I of Modification 5 does not require a portion for suspending the main body 30 from the side of the ceiling surface, and the airflow environment system 1I can be easily installed and introduced even in a space such as a ceiling. Become.

(3.6) Modification 6
Hereinafter, the airflow environment system 1J of Modification 6 will be described with reference to FIG. However, constituent elements that are substantially common to the airflow environment system 1 of the basic example are designated by the same reference numerals, and description thereof will be appropriately omitted.

The airflow environment system 1J of the modified example 6 is different from the airflow environment system 1 of the basic example in that the airflow environment system 1J of the modified example 6 includes a reflecting portion 3I having a substantially semicylindrical (cylindrical) main body 30H.

FIG. 14 is an external perspective view of the airflow environment system 1J of Modification 6. In the airflow environment system 1J of the modification 6, for example, a plurality of (here, six) chairs 401 and work desks 402 (long desks) are installed so that a plurality of people can learn and work. It is envisioned that it will be applied to the specified workspace.

The reflection part 3I of the airflow environment system 1J of the modified example 6 has a main body part 30H and one or a plurality of (here, a pair) support parts 33. The main body 30H is elongated in one direction (the direction from the front to the back in FIG. 14). The main body 30H has a substantially semi-cylindrical shape with both ends in the longitudinal direction and the lower surface open. The longitudinal direction of the main body portion 30H is along the longitudinal direction of the work desk 402. In other words, the axial direction of the substantially semi-cylindrical main body portion 30H is along the longitudinal direction of the work desk 402. The main body portion 30H is a plate-shaped portion that is curved in an arc shape so as to be convex toward the ceiling surface when viewed along the axial direction. The pair of support portions 33 are portions for suspending the main body portion 30H from the ceiling surface side.

The housing 7J of the airflow system of the airflow environment system 1J also serves as the work desk 402. The work desk 402 includes a rectangular parallelepiped base 403 that is long along the axial direction of the main body 30H, and a flat plate-shaped top plate 404 placed on the base 403. Each person can sit down on the chair 401 and place a laptop computer or the like on the top plate 404 to perform the work.

6 chairs 401 are arranged around the work desk 402. Specifically, the three chairs 401 are lined up along the axial direction of the main body 30H so as to face the first side part 402A, which is one of both side parts in the width direction of the work desk 402. Similarly, the remaining three chairs 401 are arranged along the axial direction of the main body portion 30H so as to face the second side portion 402B which is the other side portion in the width direction of the work desk 402. Here, the case where six chairs 401 are arranged around the work desk 402 is shown as an example, but the work desk 402 has various sizes and shapes depending on the number of chairs 401 and the arrangement thereof. The blower 4 and the like are housed in the base 403 of the work desk 402 (housing 7J). The intake ports 6 are arranged on the outer peripheral surface of the base 403 (illustrated at two locations in FIG. 13). Here, the width dimension (diameter dimension) of the substantially semi-cylindrical main body portion 30H is set so that each person seated on the chair 401 is wrapped by the recirculating airflow.

In the airflow environment system 1J, the discharge port 5 is composed of an opening provided at the center of the top plate 404. The opening of the top plate 404 communicates with the accommodation space in the base 403 in which the blower 4 is accommodated. Here, it is desirable that the top plate 404 is covered with, for example, a mesh-shaped protective cover so that foreign matter does not enter through the opening of the top plate 404.

In this airflow environment system 1J, the airflow that hits the substantially semi-cylindrical reflector 3I is easily recirculated. That is, the air flow discharged from the discharge port 5 hits the inner surface of the substantially semi-cylindrical main body portion 30H and is recirculated so as to be divided into both sides (two hands) in the width direction. Therefore, each person sitting on the chair 401 can perform the work while experiencing the air flow.

By the way, as another example of Modification 6, an airflow environment system 1K as shown in FIG. 15 may be provided. In the airflow environment system 1K, the three chairs 401 are arranged along the axial direction of the main body portion 30H so as to face the first side portion 402A which is one of both side portions in the width direction of the work desk 402.

Further, the reflecting portion 3J of the airflow environment system 1K has a body portion 30I which is only one side (right side in FIG. 14) of the body portion 30H of the above-described reflecting portion 3I in the width direction.

In this airflow environment system 1K, each person who sits on the chair 401 works while facing the wall 405. Even with this configuration, each person can perform work while experiencing the airflow. In particular, the wall 405 functions as the “guide portion 8” described in the fifth modification. That is, the wall 405 can guide the air flow discharged from the discharge port 5 so as to flow toward the reflecting portion 3J along the specific direction A1. As a result, the airflow environment system 1K can further improve the stability of the recirculating airflow by the wall 405.

However, like the handle (shaft) of the umbrella, the first end of the support 33 is attached to the apex (center of the first region 31) inside the main body 30, and the second end of the support 33 is It may be fixed to the deck 70 of the housing 7.

Alternatively, the support portion 33 may be formed in a substantially J shape as a whole. Specifically, the first end of the support portion 33 is attached to the outer apex of the main body portion 30 (as in the basic example), and the middle portion of the support portion 33 is curved so as to bypass the hollow portion 9. The second end of the support portion 33 may be fixed to the floor surface 101.

In the basic example, the reflecting portion 3 has an umbrella shape as a whole, but may have a curved surface 300 inside thereof, for example, it may be formed in a block shape as a whole so that only the lower surface thereof becomes the curved surface 300. It may be recessed.

In the basic example, the reflector 3 has only one curved surface 300 inside. However, the reflector 3 may have a plurality of continuous curved surfaces 300. In other words, one or a plurality of inflection points may be provided inside the reflection part 3 so as to be convex in the direction approaching the emission port 5.

In the basic example, the airflow environment system 1 operates via the operation unit J1. However, for example, it may be configured to include a motion sensor and automatically operate when a person is detected.

The body portion 30 of the reflecting portion 3 in the basic example may be able to be deflated or expanded so that the umbrella is folded around the handle. In short, the opening area of the main body 30 may be appropriately variable at the installation site.
