JP2003-97833A

By the way, according to this air purifying device, air containing smoke and the like generated from a cigarette is taken in from the air intake port located at the upper part of the handle and passes through the inside of the handle. In other words, in this air purifying device, in order to suppress the diffusion of smoke and the like, the flow path of the airflow returning to the main body side is isolated from the environmental space by the handle. Therefore, when a person in the environmental space is to experience the airflow formed in the environmental space, there is a possibility that this air purifying device cannot provide a sufficient sensation.

(1) Overview Each figure described in the following embodiments is a schematic diagram, and the ratio of the size and thickness of each component in each figure does not necessarily reflect the actual size ratio. Not necessarily.

The airflow environment system 1 according to this embodiment is configured to form an airflow (airflow) in an environmental space 100 (see FIG. 1). As an example, the environmental space 100 is assumed to be a space inside a facility, but it may be a space outside the facility (outdoors). Facilities include, for example, office buildings, theaters, movie theaters, public halls, playgrounds, complexes, restaurants, department stores, schools, hotels, inns, hospitals, nursing homes, kindergartens, libraries, museums, art galleries, underground malls, stations, or It may also be a non-residential location such as an airport. In addition to non-residential facilities, the facility may also be residential, such as a detached house or a condominium (apartment complex).

The airflow environment system 1 includes a discharge port 5 and a reflector 3. The discharge port 5 discharges an air flow flowing along at least a specific direction A1 into the environmental space 100. The reflector 3 is arranged to face the discharge port 5 in a specific direction A1, and is struck by the airflow flowing along the specific direction A1. Here, as an example, it is assumed that the "specific direction A1" is vertically upward. Therefore, the reflecting section 3 is arranged directly above the emission port 5. The reflector 3 is configured to recirculate the airflow that hits it in the environmental space 100 toward the discharge port 5 (see recirculation direction A2 in FIG. 1).

According to this configuration, the airflow flowing along the specific direction A1 is emitted into the environmental space 100, and in the same environmental space 100, the airflow that has hit the reflection section 3 is returned to the side of the ejection port 5. Therefore, compared to the case where the air flow path returning to the main body side is isolated from the environmental space by the handle, as in the air purifier described in Patent Document 1, the person inside the environmental space 100 ( It becomes easier for the user (user) to experience the airflow formed in the environmental space 100. Therefore, it is possible to improve the sensation of the airflow formed in the environmental space 100.

(2) Details Below, 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 As described above, the airflow environment system 1 is configured to form an airflow in the environmental space 100 (see FIG. 1) within a facility, for example. The airflow environment system 1 includes a ventilation system 2 and a reflection section 3, as shown in FIG.

(2.2) Ventilation System As shown in FIG. 3, the ventilation system 2 includes a ventilation device 4 (fan section), a light projection section E1, a speaker section F1, a functional section G1, a control unit H1, an operation section J1, and a housing. It has body 7 etc.

The casing 7 is configured to house or hold the blower device 4, the light projection section E1, the speaker section F1, the functional section G1, the control unit H1, the operation section J1, etc. therein. Specifically, as shown in FIG. 1, the casing 7 includes a deck 70, a support 71, and a discharge section 72, and is configured as a whole to also function as a table. . The housing 7 is installed on a floor surface 101 within an environmental space 100.

The deck 70 is formed into a circular plate shape. The deck 70 has a circular hole penetrating in the thickness direction at its center. The support column 71 is formed into a hollow truncated cone shape. The blower device 4 and the control unit H1 are housed within the support column 71. The upper surface of the strut 71 is open, and the deck 70 is attached to the upper end of the strut 71 so as to cover the open upper surface of the strut 71. Further, the support column 71 has an air intake port 6 in its peripheral wall, as shown in FIG. The air intake port 6 is composed of, for example, a plurality of slit-shaped holes that are elongated in the vertical direction. In other words, the airflow environment system 1 includes the housing 7 with the intake port 6 connected to the environmental space 100. The material of the deck 70 and the pillars 71 is not particularly limited, but it is desirable that the materials have dimensions and durability that allow the casing 7 to function as a table. A power cord is exposed at the bottom of the support 71, and the plug of the power cord is connected to, for example, a floor outlet on the floor surface 101, and connects to the air blower 4, the light projecting section E1, the speaker section F1, and the functional section G1. An operating power source can be supplied to drive the devices, etc. Casters may be provided at the bottom of the support 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 part 72 is attached so that the peripheral edge of its lower end fits within the edge of a hole in the center of the deck 70. The upper surface of the discharge section 72 is covered with a protective cover 73 having a plurality of elongated blades lined up at equal intervals in order to prevent foreign matter from entering (see FIG. 2). The light projection section E1, the speaker section F1, and the functional section G1 are housed within the emission section 72 or the support column 71. The open upper surface of the discharge part 72 corresponds to the discharge port 5 that discharges the airflow flowing along at least the specific direction A1 into the environmental space 100. In other words, the airflow environment system 1 includes the discharge port 5 in the housing 7. The material of the emission part 72 is not particularly limited, but since the light projection part E1 is housed in the emission part 72, it is desirable that the material has high heat dissipation properties.

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

The blower device 4 is configured to generate an airflow flowing along a specific direction A1 (vertically upward in this case) and send it to the discharge port 5 under the control of the control unit H1. The blower device 4 is, for example, a sirocco fan that generates an air flow containing more straight components than swirling components. The blower device 4 sucks air in the environmental space 100 through the intake port 6 and generates an airflow flowing along a specific direction A1. The blower device 4 is not limited to a sirocco fan, but may be a propeller fan. The air blower 4 is housed in a support 71 with its front facing upward, and is connected to the outlet 5 via a duct 74 (see FIG. 2) arranged in front of the air blower 4. The duct 74 is formed into a cylindrical shape with both upper and lower ends open. In short, the airflow containing many straight components generated by the blower 4 can be released from the release port 5 as an airflow flowing along a specific direction A1 (in this case, vertically upward).

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

The control unit H1 has a function of controlling the blower device 4. The control unit H1 includes, for example, a computer system with a processor and a memory. The computer system functions as the control unit H1 by the processor executing the program stored in the memory. Although the program executed by the processor is pre-recorded in the memory of the computer system here, it may also be provided recorded on a recording medium such as a memory card, or may be provided via a telecommunications line such as the Internet. .

The light projecting section E1 is configured to emit light toward the reflecting section 3 side. The light projector E1 includes, for example, one or more LEDs (Light Emitting diodes) as a light source. Further, the light projecting section E1 includes a translucent cover that covers the light source, a power supply circuit, a lighting circuit, a control circuit, and the like. At least some of the functions of the power supply circuit, the lighting circuit, and the control circuit may be integrated into the control unit H1. The operation of the light projector E1 may be controlled in conjunction with the operation of the air blower 4 under the control of the control unit H1. The emitted light color, color temperature, etc. of the light source are not particularly limited. Further, the light projecting section E1 is not limited to general lighting, and may provide dramatic lighting.

The light source of the light projecting part E1 is housed in the emission part 72 so as to face the window part 730 (see FIG. 2) of the protective cover 73, and the light emitted from the light source of the light projecting part E1 passes through the window part 730. Then, the light is irradiated toward the reflecting section 3. That is, the light from the light projecting portion E1 can be emitted upward from the emitting port 5 in the same way as the airflow. Lighting, dimming, and extinguishing of the light projecting section E1 can be executed, for example, by operating the operating section J1. By providing the light projecting section E1, it is possible to provide light (brightness) to the environmental space 100 in addition to airflow.

The speaker section F1 is configured to emit music or other sounds toward the reflecting section 3 side. The speaker section F1 includes a speaker F10 (see FIG. 2), a power supply circuit, an acoustic circuit, a control circuit, and the like. At least some of the functions of the power supply circuit, the audio circuit, and the control circuit may be integrated into the control unit H1. The operation of the speaker section F1 may be controlled in conjunction with 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 its front facing upward. Therefore, the sound output from the speaker F10 can be emitted upward from the ejection port 5 in the same way as the airflow.

Here, the speaker section F1 is assumed to be, for example, a so-called parametric speaker that uses ultrasonic waves to provide directivity. A part of the sound output from the speaker section F1 may be reflected by the reflecting section 3. Since the speaker section F1 is a parametric speaker, it provides sound to people in the environmental space 100, particularly within a specific narrow range such as right below the reflecting section 3. Turning the speaker unit F1 on and off, adjusting the volume, etc. can be performed, for example, by operating the operating unit J1. By providing the speaker section F1, sound (acoustic) can be provided to the environmental space 100 in addition to airflow.

The functional part G1 is configured to provide an additional element to the airflow discharged from the outlet 5 into 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 presentation device that includes an aromatic agent. The scent presentation device is housed within the emitting section 72. Vaporized scents from the fragrance may mix with the airflow from the blower 4 through the duct 74. As a result, the people (users) in the environmental space 100 can be provided with air with a good quality fragrance.

When the additional element includes air purification, the functional section G1 includes, for example, an air purification device. The air cleaning device is housed within the support column 71. The air purifying device includes a dust collection filter that collects fine particles such as pollen in the air sucked through the air intake port 6, a deodorizing filter, and the like. The air purified by the air purifying device can be discharged upward from the discharge port 5 as an air stream by the blower device 4 . As a result, purified air can be provided to people (users) in the environmental space 100.

Further, when the additional element includes air purification, the functional unit G1 may include, for example, a space sterilization and deodorization machine. The space sterilization and deodorization machine is housed within the support column 71. The space sterilization and deodorization machine is configured to generate hypochlorous acid and mix it into the airflow generated by the blower 4. The air flow containing hypochlorous acid is discharged upward from the discharge port 5 to sterilize the environmental space 100. As a result, purified air can be provided to people (users) in the environmental space 100.

When the additional element includes a temperature change, the functional section G1 includes, for example, an air conditioner. The air conditioner has a compressor, and cold or warm air generated by the air conditioner can be discharged upward from a discharge port 5 as an airflow by a blower device 4 . As a result, the people (users) in the environmental space 100 can be provided with air at a comfortable temperature.

When the functional unit G1 has the above-mentioned air purifying device, space sterilization and deodorizing machine, and air conditioner, turning on and off the power of these devices, adjusting various parameters, etc. can be performed, for example, by operating the operating unit J1. It is possible. Note that the control unit H1 may centrally control the functional section G1. The operation of the functional unit G1 may be controlled in conjunction with the operation of the blower device 4 under the control of the control unit H1.

By providing the functional portion G1 in this way, an additional element can be added to the air flow.

(2.3) Reflection part The reflection part 3 is arranged so as to face the emission port 5 in a specific direction A1. The reflector 3 is configured to be hit by the airflow emitted from the outlet 5 and flowing along a specific direction A1. Further, the reflection unit 3 is configured to cause the airflow that hits the environment space 100 to flow back toward the discharge port 5 side.

Hereinafter, the configuration of the reflection section 3 will be explained in detail. As shown in FIG. 1, the reflection section 3 includes a main body section 30, a support section 33, and a mounting section 35.

The main body portion 30 is formed into a substantially umbrella shape (more specifically, a curved bowl shape) with an open bottom surface. As an example, the main body part 30 is assumed to be composed of cloth and a plurality of rib parts that maintain the cloth in an umbrella shape, but is not particularly limited. The main body portion 30 may be a synthetic resin molded product or a metal molded product. Note that it is desirable to use a material that takes into consideration the acoustic characteristics of the sound output from the speaker section F1. For example, when improving the acoustic effect, a material with low sound absorption is used.

As shown in FIG. 4, the main body portion 30 has a first region 31 and a second region 32 on an inner curved surface 300 facing the discharge port 5. The first region 31 is a central region including the apex of the curved surface 300, and is a region that is hit by the airflow flowing along the specific direction A1. The second region 32 is located around the first region 31 . In other words, when the curved surface 300 is viewed from the front (from below), the second region 32 is a donut-shaped region. In the second region 32, the airflow that has hit the first region 31 flows along and is returned to the discharge port 5 side. In the main body 30 of the present embodiment, the second region 32 is curved so that the farther it is from the first region 31 along the direction (horizontal direction) orthogonal to the specific direction A1, the closer it gets to the discharge port 5 side. There is. The color of the curved surface 300 is not particularly limited, but is preferably a color that takes into account the reflection characteristics of the light emitted from the light projecting section E1.

The support portion 33 is a portion for hanging the main body portion 30 from the ceiling surface side. The support portion 33 is formed into a rod shape that is elongated in the vertical direction. The support portion 33 may be formed in a string shape. The first end (lower end in FIG. 1) of the support portion 33 is attached to the outer vertex of the main body portion 30, and the attachment portion 35 is provided at the second end (upper end in FIG. 1) of the support portion 33. .

The attachment portion 35 is configured to be detachably attached to the wiring duct 200. The wiring duct 200 is formed in the shape of a rail and is fixed to the ceiling of the facility or the like. The wiring duct 200 may be a duct rail for lighting, for example. The wiring duct 200 includes a duct body having a so-called lip groove. The mounting portion 35 has, for example, a terminal plate projecting in a T-shape. After the terminal board is inserted into the lip groove of the wiring duct 200, the mounting part 35 is rotated about 90 degrees around the axis of the mounting part 35, so that the terminal board is locked in the lip groove and attached to the wiring duct 200. It is prevented from falling out. The installation of the mounting portion 35 improves the workability of installing the reflecting portion 3.

As described above, according to the airflow environment system 1 of the present embodiment, since the reflection unit 3 is configured to recirculate the airflow that hits the environment space 100 toward the discharge port 5 side, it is possible to It is possible to improve the sensation of the airflow. In addition, since the reflecting section 3 has the first region 31 and the second region 32, a layer of airflow that is returned to the discharge port 5 side centering on the first region 31 is likely to be formed. The layer increases the possibility that the environmental space 100 will be divided into two spaces. Therefore, the sensation of airflow is further improved.

By the way, the airflow environment system 1 may further include an illumination part E2 that irradiates light toward the discharge port 5 side, as shown in FIG. The illumination part E2 is arranged in the first region 31 of the main body part 30 in the reflection part 3. The illumination unit E2 includes, for example, one or more LEDs as a light source. The lighting section E2 also includes a translucent cover that covers the light source, a power supply circuit, a lighting circuit, a control circuit, and the like. The lighting, dimming, and extinguishing of the lighting section E2 can be performed, for example, with an operation section provided in the lighting section E2. The emitted light color, color temperature, etc. of the light source are not particularly limited. Furthermore, the illumination section E2 is not limited to general illumination, and may provide dramatic illumination.

The operating power for the lighting section E2 may be supplied from the wiring duct 200. The terminal board of the attachment part 35 may also be electrically connected to the conductor part of the wiring duct 200 by being engaged with the lip groove of the wiring duct 200. A power cord may be installed inside the support portion 33, and the terminal plate of the attachment portion 35 may be electrically connected to the power circuit of the illumination portion E2 via the power cord. The power 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 board of the mounting section 35, and converts it into DC power for lighting the LED. You may. By providing the lighting section E2, it is possible to provide light (brightness) to the environmental space 100 in addition to airflow.

(2.4) Air Flow in Environmental Space Hereinafter, the air flow that can be formed in the environmental space 100 by the air flow environment system 1 will be described with reference to FIG.

FIG. 4 is a simulation result showing the airflow discharged from the discharge port 5 in the airflow environment system 1 and how the airflow hits the reflection section 3 and flows back toward the discharge port 5 (streamline). Note that the airflow environment system 1 shown in FIG. 4 is slightly different from the airflow environment system 1 shown in FIG. Further, the discharge port 5 in FIG. 4 is located at a slightly higher position (closer to the reflecting section 3) than the discharge port 5 in FIG.

As the airflow environment system 1 operates, a first flow path P1 and a second flow path P2 are formed in the environmental space 100, as shown in FIG. That is, the airflow discharged from the discharge port 5 flows toward the first region 31 of the reflection section 3 through the first flow path P1. Then, the airflow that hits the first region 31 of the reflection section 3 and spreads outward along the second region 32 of the reflection section 3 returns to the discharge port 5 side (vertically downward) through the second flow path P2. When viewed along the specific direction A1, the second flow path P2 is formed to surround the first flow path P1.

Therefore, for example, for a person (user) approaching the first flow path P1, there is a high possibility that the person (user) will come into contact with the layer of air flowing back through the second flow path P2. Therefore, the sensation of airflow is further improved. In particular, the speed of the airflow flowing back through the second flow path P2 is attenuated by the reflection section 3 and may become smaller than the speed of the airflow discharged from the discharge port 5. Therefore, compared to the case where the airflow discharged from the discharge port 5 passes through the second flow path P2 toward the reflection section 3 and flows back to the discharge port 5 side through the first flow path P1, The possibility of causing discomfort to a person (user) approaching the first flow path P1 can be reduced.

Moreover, in this embodiment, the emission port 5 and the reflection part 3 are spaced apart from each other via the hollow part 9 of the gap in the specific direction A1. The airflow discharged from the discharge port 5 (outward airflow) and the airflow flowing back to the discharge port 5 side (return airflow) flow through the hollow portion 9. In other words, there is no obstacle (such as a wall) between the discharge port 5 and the reflection section 3 that isolates the first flow path P1 and the second flow path P2 from each other. Therefore, it is possible to increase the possibility of giving a feeling of openness to the person (user) in the environmental space 100.

Furthermore, in the present embodiment, the blower device 4 sucks the airflow returned from the reflection section 3 toward the discharge port 5 side through the intake port 6, and generates an airflow flowing along a specific direction A1. It is possible to more stably circulate the airflow formed at 100. In particular, since the intake port 6 is arranged at a lower position 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 an intermediate layer X1 having a relatively low airflow velocity is formed. , the distance from the emission port 5 to the first region 31 of the reflection section 3, etc. are defined. The airflow environment system 1 forms the intermediate layer X1 in the environmental space 100, so that it is convenient for the user who uses the airflow environment system 1 to enter the intermediate layer X1 after passing through the second flow path P2. , the presence of the intermediate layer X1 separated by the airflow can be felt. Although the intermediate layer X1 is not partitioned by a physical partition wall, it is provided as if it were an environment isolated from the outside. The user can experience the intermediate layer X1 with gentle airflow as a place of relaxation. Furthermore, compared to the case where the middle layer X1 is partitioned by a physical partition wall, the cost can be reduced, and the user can easily enter the middle layer X1, which is highly convenient.

Furthermore, in the airflow environment system 1 of this embodiment, when the airflow released from the discharge port 5 returns to the side of the discharge port 5 (vertically downward) through the second flow path P2, a part of the airflow It is configured to be sucked in through the intake port 6 and circulated as a whole. Therefore, a reduction in the amount of additional elements used in the functional unit G1 can be expected.

If the additional element is, for example, air purification, there is a high possibility that the air purified by the air purifier will be discharged from the discharge port 5 and then recirculated and sucked in from the intake port 6 again. As a result, the lifespan of dust collection filters, deodorizing filters, etc. can be extended.

Furthermore, if the additional factor is, for example, a temperature change, there is a high possibility that the cold air (or warm air) generated by the air conditioner will be released from the discharge port 5 and then recirculated and sucked in again from the intake port 6. Become. As a result, the life of the air conditioner etc. can be extended and the power consumption by the air conditioner can be reduced.

Furthermore, in the airflow environment system 1 of the present embodiment, when the airflow released from the discharge port 5 returns to the side of the discharge port 5 (vertically downward) through the second flow path P2, the airflow acts as an air curtain. It is something that can function. In particular, the returning airflow can be discharged in a form that is less likely to mix with the airflow in the space inside the air curtain. As a result, for example, the additional element due to the functional part G1 contained in the air flow discharged from the discharge port 5 is confined by the air curtain. Therefore, it can be expected that the additional element will be prevented from leaking to the outside of the air curtain. In short, it becomes easier to maintain a situation in which the space inside the air curtain is filled with additional elements.

(3) Modifications The above embodiment is just one of various embodiments of the present disclosure. The embodiments described above can be modified in various ways depending on the design, etc., as long as the objective of the present disclosure can be achieved. Modifications of the above embodiment will be listed below. The modified examples described below can be applied in combination as appropriate. Below, the above embodiment may be referred to as a "basic example".

(3.1) Modification example 1
Hereinafter, an airflow environment system 1A according to modification 1 will be described with reference to FIG. 5. However, components that are substantially common to the airflow environment system 1 of the basic example are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

As a result of intensive verification, the inventors of the present disclosure found that the shape of the reflecting section 3 is more important than the height position of the outlet 5 (distance from the outlet 5 to the reflecting section 3) and the air volume and wind speed of the blower 4. It has been found that this is a factor that can greatly influence the formation of the airflow flowing back to the discharge port 5 side.

The airflow environment system 1A of Modification 1 differs from the airflow environment system 1 of the basic example in that it includes a reflecting section 3A having a different shape from the reflecting section 3 of the basic example. Note that the outlet 5 in FIG. 5 is at approximately the same height as the outlet 5 in FIG. 1 in the basic example.

The reflecting section 3A of Modification 1 includes a main body section 30A, a support section 33, and a mounting section 35 (the support section 33 and the mounting section 35 are omitted in FIG. 5). The main body portion 30A is formed in a substantially umbrella shape with an open bottom surface. However, while the main body 30 of the basic example has a bowl-shaped curved surface 300, the main body 30A of the first modification has a flat conical curved surface 300A. That is, the curved surface 300A is a conical surface.

As shown in FIG. 5, the main body portion 30A has a first region 31 and a second region 32 on an inner curved surface 300A facing the discharge port 5. The first region 31 is a central region including the apex of the curved surface 300A, and is a region that is hit by an airflow flowing along a specific direction A1. The second region 32 is located around the first region 31 . In the second region 32, the airflow that has hit the first region 31 flows along and is returned to the discharge port 5 side. In the main body portion 30A of this embodiment, the second region 32 is sloped straight so that the further away from the first region 31 in the horizontal direction, the closer it approaches the discharge port 5 side.

FIG. 5 is a simulation result showing the airflow discharged from the discharge port 5 in the airflow environment system 1A of Modification Example 1 and how the airflow hits the reflection section 3A and flows back toward the discharge port 5 side (streamline). It is.

By operating the airflow environment system 1A, as shown in FIG. 5, a first flow path P1 and a second flow path P2 are formed in the environmental space 100. That is, the airflow discharged from the discharge port 5 flows toward the first region 31 of the reflection section 3A through the first flow path P1. Then, the airflow that hits the first region 31 of the reflection section 3A and spreads outward along the second region 32 of the reflection section 3A returns to the discharge port 5 side (vertically downward) through the second flow path P2.

Here, the second flow path P2 of Modified Example 1 is different from the second flow path P2 of the basic example, and is diffused in the direction away from the ventilation system 2. Therefore, in the first modification, the volume of the intermediate layer X1 can be ensured larger than in the basic example. As a result, it becomes more likely that more users will be able to use the middle tier X1. However, in terms of "circulation" in which the airflow released from the outlet 5 returns to the intake port 6 again, the first modification may have poorer circulation than the basic example. As in the basic example, if the second region 32 is curved so that the farther it is from the first region 31, the closer it gets to the discharge port 5 side, the more layers of airflow that is returned to the discharge port 5 side are formed. become more susceptible to Therefore, for the user who uses the airflow environment system 1A, the sense of airflow is higher in the basic example than in the first modification.

Further, another example of Modification 1 (airflow environment system 1B) may include a reflection section 3B, as shown in FIG. The main body portion 30B of the reflecting portion 3B has a bowl-shaped curved surface 300B, similar to the reflecting portion 3 of the basic example. However, this curved surface 300B differs from the curved surface 300 of the basic example in that the tangential direction D1 at the opening edge is approximately parallel to the vertical direction. That is, the tangential direction of the opening edge of the curved surface 300 in the basic example is inclined with respect to the vertical direction so as to expand outward as it goes downward.

The reflecting section 3B in FIG. 6 has higher circulation than the basic example and the example in FIG. Therefore, a layer of airflow flowing back toward the discharge port 5 side is more likely to be formed, and the sensation of the airflow can be improved. However, the volume of the intermediate layer X1 tends to become small, reducing the possibility that the user will be able to experience the presence of the intermediate layer X1 separated by the airflow. Note that it is possible to increase the volume of the intermediate layer X1 by increasing the air volume of the blower 4 or adjusting the height position of the outlet 5.

Yet another example of Modification 1 (airflow environment system 1C) may include a reflection section 3C, as shown in FIG. The main body portion 30C of the reflecting portion 3C has a bowl-shaped curved surface 300C, similar 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 that it narrows inward as it goes downward.

The reflective section 3C in FIG. 7 has higher circulation than the example in FIG. Therefore, a layer of airflow flowing back toward the discharge port 5 side is more likely to be formed, and the sensation of the airflow can be improved. However, the volume of the intermediate layer X1 tends to become even smaller. Note that it is possible to increase the volume of the intermediate layer X1 by increasing the air volume of the blower 4 or adjusting the height position of the outlet 5.

Yet another example of Modification 1 (airflow environment system 1D) may include a reflection section 3D, as shown in FIG. The main body portion 30D of the reflecting portion 3D has a bowl-shaped curved surface 300D, similar to the reflecting portion 3 of the basic example. However, this curved surface 300D differs in that the distance (depth W1) from the opening surface to the apex is deeper than the depth of the curved surface 300 of the basic example. Note that the tangential direction D3 at the opening edge of the curved surface 300D is approximately parallel to the vertical direction.

The reflective portion 3D in FIG. 8 also has relatively high circulation. Therefore, a layer of airflow flowing back toward the discharge port 5 side is more likely to be formed, and the sensation of the airflow can be improved. However, the volume of the intermediate layer X1 tends to be small. Note that it is possible to increase the volume of the intermediate layer X1 by increasing the air volume of the blower 4 or adjusting the height position of the outlet 5.

(3.2) Modification 2
Hereinafter, an airflow environment system 1E according to modification 2 will be described with reference to FIG. 9. However, components that are substantially common to the airflow environment system 1 of the basic example are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

In the airflow environment system 1 of the basic example, the discharge port 5 is provided in a casing 7 configured to also function as a table. The airflow environment system 1E of the second modification differs from the airflow environment system 1 of the basic example in that the discharge port 5 is provided directly on the floor surface 101.

Further, in the airflow environment system 1 of the basic example, the reflection section 3 has a hanging type structure. The airflow environment system 1E of the second modification differs from the airflow environment system 1 of the basic example in that it includes a reflection section 3E having an embedded structure.

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

The reflecting section 3E of the second modification is, for example, embedded in one of the plurality of square-type ceiling materials 151 in the system ceiling 150. The reflecting portion 3E may be embedded over a plurality of (for example, four) ceiling materials 151. For example, the reflecting portion 3E is directly fixed to a hanging bolt of a ceiling slab in the attic.

According to the second modification, compared to a case where the outlet 5 is arranged on one side of a dedicated housing, for example, the possibility that the aesthetic appearance of the environmental space 100 will be impaired can be reduced, and convenience can be improved. . Additionally, parts (floor and housing) can be standardized.

As another example of Modification 2, the ceiling material 151 itself may have a reflective portion 3E having an umbrella-shaped concave curved surface 300.

As yet another example of Modification 2, the airflow environment system 1E may include a plurality of sets of one reflective section 3 and one discharge port 5 that correspond to each other. Specifically, a plurality of reflecting sections 3E may be embedded in the system ceiling 150, and a plurality of emission ports 5 may be provided on the floor surface 101 in one-to-one correspondence with the plurality of reflecting sections 3E. In this case, the number of blowers 4 and control units H1 does not necessarily have to be the same as the number of outlets 5. For example, the airflow generated by one blower 4 may pass through a duct installed under the floor and be released from a plurality of outlets 5. Alternatively, one control unit H1 may be installed in a management room or the like within a facility and configured to be able to centrally manage a plurality of air blowers 4 at once. Similarly, in the basic example, the airflow environment system 1 includes a plurality of sets of one reflecting section 3 and one discharge port 5, and one control unit H1 controls a plurality of blowers. 4 may be configured to be able to be centrally managed.

(3.3) Modification 3
Hereinafter, the airflow environment system 1F of modification 3 will be described with reference to FIG. 10. However, components that are substantially common to the airflow environment system 1 of the basic example are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

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 is assumed to be installed in a hotel lobby, etc., and has a structure that takes convenience and design into consideration. The housing 7F of the blower system 2 of the airflow environment system 1F is configured to also function as a long table. The housing 7F also has a bottle-shaped ornament 75, the open top of which serves as the discharge port 5. The figurine 75 has an opening at the bottom, and the airflow from the blower device 4 housed in the long table can be discharged upward from the outlet 5 through the opening of the figurine 75. Furthermore, one or more lobby sofas 301 are installed so as to surround the housing 7F.

The reflecting section 3F of the third modification has a cylindrical main body section 30F with an open bottom surface. The reflecting section 3F does not have the support section 33 of the basic example, and the main body section 30F is directly attached to the ceiling surface. The lobby sofa 301 is arranged so as to generally fit within the projection area of the opening surface of the main body portion 30F. Depending on the number and shape of the lobby sofas 301, reflecting portions 3F having various sizes and shapes are installed.

In this way, by providing airflow using the airflow environment system 1F in a hotel lobby, etc., it is possible to provide a localized space that is different from the surrounding area in the environment space 100 without being blocked by a physical partition wall. . Furthermore, by appropriately combining light, sound, and additional elements (scent, etc.) with the air flow, it is possible to provide an even more comfortable place for relaxation.

FIG. 11 is an external perspective view of another example of modification 3 (airflow environment system 1G). The airflow environment system 1G shown in FIG. 11 is assumed to be installed in a waiting room or the like in a hospital, and has a structure that takes convenience and sterilization into consideration. The ventilation system 2 of the airflow environment system 1G has a pole-shaped housing 7G. The discharge port 5 is formed on the upper surface of the pole-shaped housing 7G. The air flow of the blower device 4 housed in the pole-shaped housing 7G can be discharged upward from the discharge port 5. Further, donut-shaped waiting chairs 302 are arranged to surround the periphery of the housing 7G.

The reflecting section 3G in FIG. 11 has an umbrella-shaped main body section 30G with an open bottom surface. The waiting chair 302 is arranged so as to generally fit within the projection area of the opening surface of the main body 30G. The reflective section 3G in FIG. 11 has relatively large dimensions so that it can be used by as many users (patients) as possible.

In this way, by providing airflow using the airflow environment system 1G in a hospital waiting room, etc., it is possible to provide a localized space that is different from the surrounding area in the environment space 100 without being blocked by a physical partition wall. can. Moreover, the air flow passing through the second flow path P2 has an effect as a barrier function, and the risk of in-hospital infection can be reduced. Furthermore, by appropriately combining additional elements (air purification: hypochlorous acid, etc.) with the air flow, an even cleaner place can be provided.

(3.4) Modification example 4
Hereinafter, an airflow environment system 1H according to modification 4 will be described with reference to FIG. 12. However, components that are substantially common to the airflow environment system 1 of the basic example are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

The airflow environment system 1H of the fourth modification differs from the airflow environment system 1 of the basic example in that the discharge port 5 is arranged on one surface of the member constituting the chair 303. Note that the reflection unit 3 of the airflow environment system 1H is the same as the basic example, so a description thereof will be 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, substantially rectangular parallelepiped seat 76, and a prismatic backrest 77 provided at the center of the upper surface (seat surface 760) of the seat 76. The blower 4 and the like are housed within the seat 76 or the backrest 77.

The discharge port 5 is provided on the upper end surface of the backrest 77. Further, the intake port 6 is provided on the seat surface 760 of the seat portion 76. Specifically, for example, a plurality of square pieces 761 are assembled so as to be lined up at a predetermined interval, and the gap between adjacent square pieces 761 becomes the air intake port 6.

According to this modification 4, compared to a case where the discharge port 5 is arranged on one side of a dedicated housing, for example, the possibility that the aesthetic appearance of the environmental space 100 will be impaired can be reduced, and convenience can be improved. . In addition, parts (chair and housing) can be standardized.

(3.5) Modification example 5
Hereinafter, an airflow environment system 1I according to modification 5 will be described with reference to FIG. 13. However, components that are substantially common to the airflow environment system 1 of the basic example are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

The airflow environment system 1I of the fifth modification differs from the airflow environment system 1 of the basic example in that it further includes a guide section 8.

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

The reflecting section 3H has a main body section 30 and a support section 33. In FIG. 13, the main body portion 30 of the reflecting portion 3H is illustrated only with a dashed line. The main body part 30 of the reflective part 3H has a substantially umbrella shape with an open bottom surface, and is substantially the same as the main body part 30 of the reflective part 3 of the basic example.

The support part 33 of the reflection part 3H is different from the support part 33 of the reflection part 3 of the basic example, and is not a part for hanging the main body part 30 from the ceiling side, but protrudes from the pedestal B1 and supports the main part 30. ing. That is, the support part 33 of the reflection part 3H is a part corresponding to the handle (shaft) of the umbrella (main body part 30). The first end (upper end) of the support part 33 is attached to the inner vertex of the main body part 30, and the second end (lower end) of the support part 33 is fixed to the base B1. However, here, the support part 33 of the reflection part 3H is realized by the guide part 8. In other words, the guide section 8 supports (the main body section 30 of) the reflecting section 3H.

The housing 7I of the blower system 2 of the airflow environment system 1I also serves as a pedestal B1 on which (a plurality of) people can sit. In other words, the airflow environment system 1I includes the pedestal B1. The pedestal B1 has a flat cylindrical shape in a specific direction A1. The pedestal B1 functions as a chair on which a person can sit. The center axis of the pedestal B1 generally coincides with the center axis of the support portion 33 corresponding to the handle of the umbrella (main body portion 30). The blower device 4 and the like are housed in the pedestal B1 (casing 7I). The intake ports 6 are arranged on the outer circumferential surface of the pedestal B1 (two locations are shown in FIG. 13). Here, the outer diameter of the main body part 30 of the umbrella-shaped reflective part 3H is set larger than the outer diameter of the base B1. As a result, the airflow that hits the reflection section 3H is facilitated to circulate.

The guide section 8 is configured to guide the airflow flowing toward the reflection section 3H along a specific direction A1. The guide portion 8 is fixed to the base B1. The guide part 8 has a partition part 80 (one or more) that divides the environmental space 100 into two or more parts along the circumferential direction D4 of the specific direction A1. Here, as an example, there are a total of four partitions 80 (only three are shown in FIG. 13), and the environmental space 100 is divided into four. Each partition part 80 has a long plate shape along a specific direction A1. Here, the four plate-shaped partitions 80 guide the airflow flowing toward the reflecting section 3H along a specific direction A1.

The four partitions 80 protrude from the base B1 along a specific direction A1. Here, the four partitions 80 are arranged so as to divide the area of the upper surface of the pedestal B1 into four equal parts about the central axis of the pedestal B1, when the pedestal B1 is viewed from above. That is, each of the quarterly divided areas on 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 to such an extent that one person can sit in each fan-shaped area. That is, here, the setting is such that four people can sit on the pedestal B1 at the same time. However, the number of people who can be seated at the same time is not limited to four.

The outer edge (the edge on the opposite side of the central axis) of each partition portion 80 includes an intermediate edge 800 extending along the up-down direction, a first edge 801 continuous from the lower part of the intermediate edge 800, and a first edge 801 extending from the bottom of the intermediate edge 800. It is composed of a second edge 802 continuous from the top and a third edge 803 continuous from the tip of the second edge 802. The first edge 801 is curved so as to widen toward the periphery of the pedestal B1 as it approaches the upper surface of the pedestal B1 when viewed along the thickness direction of each partition portion 80. The second edge 802 is curved to be convex upward. The third edge 803 is curved so as to hang down along the inner surface of the reflective section 3H. The four partitions 80 function as a plurality of ribs that stably hold the umbrella-shaped reflector 3H by contacting the inner surface of the reflector 3H at each third edge 803.

The guide portion 8 further includes a backrest portion 81 that protrudes from the upper surface of the base B1 along a specific direction A1 between two adjacent partition portions 80 of the four partition portions 80. A total of four backrest parts 81 are provided, one in each fan-shaped area of the base B1 (only two are shown in FIG. 13). A person seated in each fan-shaped area of the pedestal B1 can use the backrest part 81 to relax.

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

According to the airflow environment system 1I of this modification 5, by providing the guide portion 8, the stability of the circulating airflow can be further improved.

Further, since the guide section 8 has the partition section 80, it is possible to individually improve the sensation of airflow in each of the plurality of spaces divided by the partition section 80. Furthermore, since the partition part 80 protrudes from the pedestal B1 along the specific direction A1, each person can sit on the pedestal B1 and experience the airflow within each space divided by the partition part 80. Further, since the guide section 8 supports the reflection section 3H, there is no need to provide a support member for supporting the reflection section 3H separately from the guide section 8 that guides the airflow.

In the airflow environment system 1I of this fifth modification, each person can sit in the area between the two adjacent partitions 80 on the upper surface of the pedestal B1, thereby creating a space surrounded by the two partitions 80. Inside, you can experience the airflow released from the corresponding outlet 5. Particularly, by being partitioned by the partition part 80, a certain distance can be maintained from the person sitting next to the person, and there is a high possibility that the line of sight from the person sitting next to the person will be blocked. As a result, each person using the airflow environment system 1I can be given a sense of security.

In addition, the airflow environment system 1I of Modification 5 does not require a part for hanging the main body 30 from the ceiling side, and the airflow environment system 1I can be easily installed even in a space with an open ceiling, for example. Become.

(3.6) Modification 6
Hereinafter, an airflow environment system 1J according to modification 6 will be described with reference to FIG. 14. However, components that are substantially common to the airflow environment system 1 of the basic example are given the same reference numerals, and descriptions thereof will be omitted as appropriate.

The airflow environment system 1J of the sixth modification differs from the airflow environment system 1 of the basic example in that it includes a reflection section 3I having a main body section 30 that is approximately semicylindrical (semi-cylindrical).

FIG. 14 is an external perspective view of an airflow environment system 1J according to modification 6. For example, the airflow environment system 1J of Modification 6 is equipped with a plurality of (six in this case) chairs 401 and work desks 402 (long desks) so that a plurality of people can use them to study or work. It is assumed that this will be applied to the workspace where the

The reflecting section 3I of the airflow environment system 1J of Modification 6 includes a main body section 30 and one or more (here, a pair) support sections 33. The main body portion 30 is elongated in one direction. The main body portion 30 has a substantially semi-cylindrical shape with both longitudinal ends and the lower surface thereof open. The longitudinal direction of the main body part 30 is along the longitudinal direction of the work desk 402. In other words, the axial direction of the approximately semi-cylindrical main body portion 30 is along the longitudinal direction of the work desk 402. The main body portion 30 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 parts 33 are parts for hanging the main body part 30 from the ceiling surface side.

The housing 7J of the blower system 2 of the airflow environment system 1J also serves as a work desk 402. The work desk 402 includes a rectangular parallelepiped-shaped base 403 extending along the axial direction of the main body 30 and a flat plate-shaped top plate 404 placed on the base 403. Each person can sit on a chair 401, place a laptop computer or the like on the top plate 404, and perform work.

Six 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 part 30 so as to face the first side part 402A, which is one of the both sides in the width direction of the work desk 402. Similarly, the remaining three chairs 401 are lined up along the axial direction of the main body part 30 so as to face the second side part 402B, which is the other of the both sides in the width direction of the work desk 402. The air blower 4 and the like are housed in the base 403 of the work desk 402 (casing 7J). The intake ports 6 are arranged on the outer peripheral surface of the base 403 (two locations are shown in FIG. 13). Here, the width dimension (diameter dimension) of the approximately semi-cylindrical main body portion 30 is set so that each person seated on the chair 401 is surrounded by the circulating airflow.

In the airflow environment system 1J, the discharge port 5 is constituted by an opening provided in the center of the top plate 404. The opening of the top plate 404 communicates with an accommodation space in the base 403 in which the blower device 4 is accommodated. Here, it is desirable that the top plate 404 be covered with a mesh-like protective cover, for example, to prevent foreign matter from entering through the opening.

This airflow environment system 1J has a configuration in which the airflow that hits the substantially semi-cylindrical reflection section 3I is easily circulated. That is, the airflow discharged from the discharge port 5 hits the inner surface of the approximately semi-cylindrical main body portion 30, and is returned so as to be divided into both sides (two hands) in the width direction. Therefore, each person sitting on the chair 401 can perform work while experiencing the airflow.

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, three chairs 401 are lined up along the axial direction of the main body part 30 so as to face the first side part 402A, which is one of the both sides of the work desk 402 in the width direction. On the other hand, the second side portion 402B, which is the other of the both sides in the width direction of the work desk 402, is in a state close to a wall 405 that is a construction material of a building or the like.

Further, the reflecting section 3J of this airflow environment system 1K has a main body section 30 that is only one side in the width direction (the right side in FIG. 14) of the main body section 30 of the above-mentioned reflecting section 3I.

In this airflow environment system 1K, each person sitting on a chair 401 works while facing a wall 405. With this configuration as well, work can be performed while experiencing the airflow. In particular, the wall 405 functions as the "guide portion 8" described in the fifth modification. In other words, the wall 405 can guide the airflow flowing toward the reflecting section 3J along the specific direction A1. As a result, the stability of the circulating air flow can be further improved.

(3.7) Other Modifications The blower device 4, light projecting section E1, speaker section F1, and functional section G1 in the basic example are not essential components in the airflow environment system 1, and the airflow environment system 1 It is not necessary to include at least one of these. Further, the air intake port 6 in the basic example is not an essential component in the airflow environment system 1, and the airflow environment system 1 does not need to be provided with the air intake port 6.

In the basic example, the specific direction A1 is parallel to the vertical direction and is also vertically upward, but may also be vertically downward. Alternatively, the specific direction A1 may be a direction intersecting the vertical direction. However, if the specific direction A1 is at least parallel to the vertical direction, it is easier to form an air flow that flows back toward the discharge port 5 side.

In the basic example, both the light projection section E1 and the illumination section E2 are provided, but only one of them may be provided. In addition to the wiring duct 200 of the basic example, the object to which the attachment portion 35 is attached may be a rail member that does not have a power feeding function (conductor portion).

In the basic example, the reflecting section 3 is configured to suspend the main body section 30 from the ceiling surface side via the supporting section 33. However, like the handle (shaft) of an umbrella, the first end of the support part 33 is attached to the inner vertex of the main body part 30 (the center of the first region 31), and the second end of the support part 33 is It may be fixed to the deck 70 of the housing 7.

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

In the basic example, the reflecting section 3 has an umbrella shape as a whole, but it is sufficient that the reflecting section 3 has a curved surface 300 on the inside thereof. It may be concave.

In the basic example, the reflecting section 3 has only one curved surface 300 inside thereof. However, the reflecting section 3 may have a plurality of continuous curved surfaces 300. In other words, there may be one or more inflection points that are convex in the direction approaching the emission port 5 inside the reflection section 3 .

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

The main body 30 of the reflector 3 in the basic example may be able to collapse or expand, like an umbrella being folded around its handle. In short, the opening area of the main body 30 may be changed as appropriate at the installation site.

(4) Summary As explained above, the airflow environment system (1, 1A to 1K) according to the first aspect includes the discharge port (5) and the reflection section (3, 3A to 3J). The outlet (5) releases an air flow flowing along at least a specific direction (A1) into the environmental space (100). The reflecting portions (3, 3A to 3J) are arranged to face the discharge port (5) in a specific direction (A1), and are hit by the airflow flowing along the specific direction (A1). The reflectors (3, 3A to 3J) are configured to recirculate the airflow that hits them in the environmental space (100) towards the outlet (5). According to the first aspect, it is possible to improve the sensation of airflow formed in the environmental space (100).

Regarding the airflow environment system (1, 1A to 1K) according to the second aspect, in the first aspect, the reflecting section (3, 3A to 3J) has a first region (31) and a second region (32). It is preferable to have the following. The first region (31) is hit by an airflow flowing along a specific direction (A1). The second region (32) is located around the first region (31), and the air flow that hits the first region (31) flows along it and is returned to the discharge port (5) side. According to the second aspect, for example, a layer of air flow that is returned to the outlet (5) side around the first region (31) is likely to be formed, and the layer allows the environmental space (100) to be divided into two There is a high possibility that it will be divided into spaces. Therefore, the sensation of airflow is further improved.

Regarding the airflow environment system (1, 1A to 1K) according to the third aspect, in the second aspect, the second area (32) is arranged in the first area (31) along the direction orthogonal to the specific direction (A1). ) is preferably curved so that the farther it is from the outlet (5), the closer it gets to the outlet (5). According to the third aspect, it becomes easier to form a layer of air flow that is returned to the side of the discharge port (5).

Regarding the airflow environment system (1, 1A to 1K) according to the fourth aspect, in any one of the first to third aspects, the environmental space (100) includes a first flow path (P1) and a first flow path (P1). It is preferable that two channels (P2) are formed. In the first flow path (P1), the airflow discharged from the discharge port (5) flows toward the reflecting portions (3, 3A to 3J). In the second flow path (P2), the airflow that has hit the reflecting portions (3, 3A to 3J) flows back toward the discharge port (5). When viewed along the specific direction (A1), the second flow path (P2) is formed to surround the first flow path (P1).
