By the way, according to this air purifier, the air containing smoke and the like generated from cigarettes is taken in from the air suction port at the upper part of the handle and passes through the inside of the handle. In other words, in this air purifier, in order to suppress the diffusion of smoke and the like, the flow path of the air flow returning to the side of the main body portion is isolated from the environmental space by the handle portion. Therefore, when the airflow formed in the environmental space is to be experienced by a person in the environmental space, it may not be possible to obtain sufficient sensation with this air purifier. Further, when a speaker that provides sound (acoustic) is provided in the environmental space, the sound (acoustic) leaks out of the environmental space, which may cause discomfort to a person outside the environmental space.

This disclosure is made in view of the above reasons, and it is possible to improve the sensation of the airflow formed in the environmental space and to provide sound (sound) to a person who is within a specific narrow range in the environmental space . The purpose is to provide an acoustic system .

The acoustic system of one aspect of the present disclosure has a speaker unit that outputs sound toward the hollow portion, and a main body portion that reflects a part of the sound output from the speaker unit toward the hollow portion. It is provided with a reflecting portion arranged so as to be sandwiched and opposed to the speaker portion, and a support portion for suspending the main body portion from the side of the ceiling surface .

According to the present disclosure, there are advantages that it is possible to improve the sensation of the airflow formed in the environmental space and to provide sound (sound) to a person who is within a specific narrow range in the environmental space. ..

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

The acoustic system 1 according to the present embodiment is configured to form an air flow (air flow) in the environmental space 100 (see FIG. 1). The environmental space 100 is assumed to be a space inside the facility as an example, but may be a space outside the facility (outdoor). Facilities include, for example, office buildings, theaters, movie theaters, public halls, amusement parks, complex facilities, restaurants, department stores, schools, hotels, inns, hospitals, geriatric homes, kindergartens, libraries, museums, museums, underground streets, stations, or It may be a non-residential facility such as an airport. In addition to non-residential facilities, the facilities may be residential such as detached houses or condominiums (apartments).

The sound system 1 includes a discharge port 5 and a reflection unit 3. The discharge port 5 discharges an air flow flowing along at least a specific direction A1 into the environmental space 100. The reflecting portion 3 is arranged so as to face the discharge port 5 in the specific direction A1, and is hit by an air flow flowing along the specific direction A1. Here, as an example, it is assumed that the "specific direction A1" is vertically upward. Therefore, the reflective portion 3 is arranged directly above the discharge port 5. Then, the reflecting unit 3 is configured to recirculate the hit air flow to the side of the discharge port 5 in the environmental space 100 (see the recirculation direction A2 in FIG. 1).

According to this configuration, the air flow flowing along the specific direction A1 is discharged to the environmental space 100, and in the same environmental space 100, the air flow hitting the reflective portion 3 is returned to the side of the discharge port 5. Therefore, a person who is in the environmental space 100 as compared with the case where the air flow path returning to the main body side is isolated from the environmental space by the handle portion as in the air purifying device described in Patent Document 1. The user) can easily 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 Hereinafter, the overall configuration of the acoustic 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 acoustic system 1 is configured to form an air flow in, for example, the environmental space 100 (see FIG. 1) in the facility. As shown in FIG. 1, the acoustic system 1 includes a blowing system 2 and a reflecting unit 3.

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

The housing 7 is configured to accommodate or hold the blower 4, the light projecting unit E1, the speaker unit 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 support column 71, and a discharge portion 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 the shape of a circular plate. The deck 70 has a circular hole penetrating in the thickness direction at the center thereof. The column 71 is formed in the shape of a hollow truncated cone. The blower 4 and the control unit H1 are housed in the support column 71. The upper surface of the column 71 is open, and the deck 70 is attached to the upper end of the column 71 so as to close the open upper surface of the column 71. Further, as shown in FIG. 1, the support 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 elongated in the vertical direction. In other words, the acoustic system 1 includes an intake port 6 connected to the environmental space 100 in the housing 7. The materials of the deck 70 and the column 71 are not particularly limited, but it is desirable that the housing 7 has dimensions and durability enough to function as a table. The power cord is exposed at the bottom of the support column 71, and the plug of the power cord is connected to, for example, the floor outlet of the floor surface 101, and the blower 4, the light projecting unit E1, the speaker unit F1, and the functional unit G1 are connected. And the like can be supplied with an operating power source for driving. Casters may be provided on the bottom of the column 71 so that the housing 7 can be easily moved.

The discharge portion 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 at the lower end thereof fits within the edge of the hole in the central portion of the deck 70. The upper surface of the discharge portion 72 is covered with a protective cover 73 in which a plurality of elongated blades are arranged at equal intervals in order to prevent foreign matter from entering (see FIG. 2). The light projecting unit E1, the speaker unit F1, and the functional unit G1 are housed in the emission unit 72 or the support column 71. The open upper surface of the discharge portion 72 corresponds to a discharge port 5 that discharges an air flow flowing along at least a specific direction A1 to the environmental space 100. In other words, the acoustic system 1 includes a discharge port 5 in the housing 7. The material of the light emitting unit 72 is not particularly limited, but since the light projecting unit E1 is housed in the light emitting unit 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 emission unit 72. The user can turn on / off the power of the ventilation system 2 by operating the operation unit J1. When the control unit H1 receives the operation of turning on the power in 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 flowing along a specific direction A1 (here, vertically upward) under the control of the control unit H1 and send it to the discharge port 5. The blower 4 is, for example, a sirocco fan that generates an air flow containing a large amount of a linear component as compared with a swirling component. The blower device 4 sucks the air in the environmental space 100 from the intake port 6 and generates an air flow flowing along the specific direction A1. The blower device 4 is not limited to the sirocco fan, and may be a propeller fan. The blower device 4 is housed in a support column 71 with its front surface facing upward, and is connected to a discharge port 5 via a duct 74 (see FIG. 2) arranged in front of the blower device 4. The duct 74 is formed in a cylindrical shape with both upper and lower ends open. In short, the air flow containing a large amount of the straight component generated by the blower 4 can be discharged from the discharge port 5 as an air flow flowing along the specific direction A1 (here, vertically upward) as it is.

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

The control unit H1 has a function of controlling the blower device 4. The control unit H1 has, for example, a computer system having a processor and a memory. Then, when the processor executes the program stored in the memory, the computer system functions as the control unit H1. The program executed by the processor is 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 may be provided through a telecommunication line such as the Internet. ..

The light projecting unit E1 is configured to irradiate light toward the reflecting unit 3. The light projecting unit E1 includes, for example, one or a plurality of LEDs (LightEmittingdiode) as a light source. Further, the light projecting unit E1 includes a translucent cover for covering the light source, a power supply circuit, a lighting circuit, a control circuit, and the like. 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 so as to be interlocked with 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 provide directing lighting.

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

The speaker unit F1 is configured to sound a sound such as music toward the reflection unit 3. 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 so as to be interlocked with the operation of the blower device 4 under the control of the control unit H1. The speaker F10 is arranged so as to face the protective cover 73 with its front surface facing upward. Therefore, the sound output from the speaker F10 can be emitted upward from the discharge port 5 in the same manner as the air flow.

Here, as an example, the speaker unit F1 assumes a so-called parametric speaker that has directivity by using ultrasonic waves. A part of the sound output from the speaker unit F1 may be reflected by the reflection unit 3. Since the speaker unit F1 is a parametric speaker, sound is provided to a person who is in a specific narrow range such as directly under the reflective unit 3 in the environmental space 100. The power on / off of the speaker unit F1 and the volume adjustment can be executed by, for example, operating the operation unit J1. By providing the speaker unit F1, sound (sound) can be provided to the environmental space 100 in addition to the air flow.

The functional unit G1 is configured to add an additional element to the air flow discharged from the discharge port 5 to the environmental space 100. Additional elements include at least one of scent, air purification, and temperature changes.

When the additional element contains a scent, the functional unit G1 has, for example, a scent presenting device containing a fragrance. The scent presenting device is housed in the emitting unit 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, it is possible to provide a person (user) in the environmental space 100 with high-quality scented air.

If the additional element comprises air purification, functional unit G1 has, for example, an air purifier. The air purifier is housed in the column 71. The air purifier has a dust collecting filter that collects fine particles such as pollen in the air sucked from the intake port 6, a filter for deodorizing, and the like. The air purified by the air purifier can be discharged upward from the discharge port 5 as an air flow by the blower 4. As a result, purified air can be provided to the person (user) in the environmental space 100.

Further, when the additional element includes air purification, the functional unit G1 may have, for example, a space sterilization deodorizer. The space sterilization deodorizer is housed in the support column 71. The space sterilization deodorizer is configured to generate hypochlorous acid and mix it with the air flow generated by the blower 4. The air stream 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 the person (user) in the environmental space 100.

If the additional element comprises a temperature change, the functional unit G1 has, for example, an air conditioner. The air conditioner has a compressor, and the cold air or warm air generated by the air conditioner can be discharged upward from the discharge port 5 as an air flow by the blower 4. As a result, it is possible to provide air at a comfortable temperature to a person (user) in the environmental space 100.

When the functional unit G1 has the above-mentioned air purifier, space sterilization deodorizer, and air conditioner, the power of these devices can be turned on and off, and various parameters can be adjusted, for example, by operating the operation unit J1. It is possible. The control unit H1 may centrally control the functional unit G1. The operation of the functional unit G1 may be controlled so as to be interlocked with the operation of the blower device 4 under the control of the control unit H1.

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

(2.3) Reflecting unit The reflecting unit 3 is arranged so as to face the discharge port 5 in a specific direction A1. The reflection unit 3 is configured to be hit by an air flow flowing along a specific direction A1 discharged from the discharge port 5. Further, the reflection unit 3 is configured to return the hit air flow to the side of the discharge port 5 in the environmental space 100.

Hereinafter, the configuration of the reflective unit 3 will be described in detail. As shown in FIG. 1, the reflective portion 3 has a main body portion 30, a support portion 33, and a mounting portion 35.

The main body 30 is formed in a substantially umbrella shape (more specifically, a curved bowl shape) with an open lower surface. As an example, the main body portion 30 is assumed to be composed of a fabric and a plurality of bone portions that maintain the fabric in an umbrella shape, but is not particularly limited. The main body portion 30 may be a molded product of synthetic resin or a molded product of metal. It should be noted that a material considering the acoustic characteristics of the sound output from the speaker unit F1 is desirable, and for example, when enhancing the acoustic effect, a material having 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 the inner curved surface 300 facing the discharge port 5. The first region 31 is a central region including the vertices of the curved surface 300, and is a region to which an air flow flowing along a 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 below), the second region 32 is a donut-shaped region. The second region 32 flows along the air flow hit by the first region 31 and returns to the side of the discharge port 5. In the main body portion 30 of the present embodiment, the second region 32 is curved so as to be closer to the discharge port 5 as the distance from the first region 31 increases along the direction (horizontal direction) orthogonal to the specific direction A1. There is. The color of the curved surface 300 is not particularly limited, but a color that takes into consideration the reflection characteristics of the light emitted from the light projecting unit E1 is desirable.

The support portion 33 is a portion for suspending the main body portion 30 from the side of the ceiling surface. The support portion 33 is formed in a rod shape that is long 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 apex 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 mounting 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 a 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 inserting the terminal plate into the lip groove of the wiring duct 200, the mounting portion 35 is rotated about 90 degrees around the axis of the mounting portion 35 so that the terminal plate is locked to the lip groove with respect to the wiring duct 200. It will be stopped. Since the mounting portion 35 is provided, the workability related to the installation of the reflecting portion 3 is improved.

As described above, according to the acoustic system 1 of the present embodiment, the reflective portion 3 is configured in the environmental space 100 so as to recirculate the hit air flow to the side of the discharge port 5, and thus is formed in the environmental space 100. It is possible to improve the sensation of airflow. Further, since the reflective portion 3 has the first region 31 and the second region 32, it becomes easy to form a layer of air flow that is returned to the side of the discharge port 5 with the first region 31 as the center. There is a high possibility that the environmental space 100 is divided into two spaces by the layer. Therefore, the sensation of the airflow is further improved.

By the way, as shown in FIG. 1, the acoustic system 1 may further include an illumination unit E2 that irradiates light toward the emission port 5. The illumination unit E2 is arranged in the first region 31 of the main body unit 30 in the reflection unit 3. The illumination unit E2 includes, for example, one or a plurality of LEDs as a light source. Further, 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. The lighting unit E2 can be turned on, dimmed, and turned off by, for example, an operation unit provided in the lighting unit E2. The emission color and color temperature of the light source are not particularly limited. Further, the lighting unit E2 is not limited to general lighting, and may provide directing lighting.

Then, the operating power supply of the lighting unit E2 may be supplied from the wiring duct 200. By locking the terminal plate of the mounting portion 35 to the lip groove of the wiring duct 200, electrical connection with the conductor portion of the wiring duct 200 may also be achieved. A power cord may be built in the support portion 33, and the terminal plate of the mounting portion 35 may be electrically connected to the power supply circuit of the lighting unit E2 via the power cord. The power supply circuit of the lighting unit E2 receives, for example, commercial AC power from the conductor portion of the wiring duct 200 via the power cord in the support portion 33 and the terminal plate of the mounting portion 35, and converts it into DC power for lighting the LED. You may. By providing the illumination unit E2, light (brightness) can be provided to the environmental space 100 in addition to the air flow.

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

FIG. 4 is a simulation result showing an air flow discharged from the discharge port 5 in the acoustic system 1 and a state (streamline) in which the air flow hits the reflection unit 3 and returns to the side of the discharge port 5. Note that the acoustic system 1 of FIG. 4 is slightly different from the acoustic system 1 of FIG. 1, and the housing 7, the support portion 33, and the like are omitted and schematically. Further, the discharge port 5 of FIG. 4 is located at a slightly higher position (position close to the reflection portion 3) than the discharge port 5 of FIG.

When the acoustic system 1 operates, as shown in FIG. 4, a first flow path P1 and a second flow path P2 are formed in the environmental space 100. That is, the air flow discharged from the discharge port 5 flows toward the first region 31 of the reflection unit 3 through the first flow path P1. Then, the air flow that hits the first region 31 of the reflection unit 3 and spreads outward along the second region 32 of the reflection unit 3 returns to the side of the discharge port 5 (vertically downward) through the second flow path P2. When viewed along a specific direction A1, the second flow path P2 is formed so as to surround the first flow path P1.

Therefore, for example, for a person (user) approaching the side of the first flow path P1, there is a high possibility that the person (user) will come into contact with the layer of the air flow flowing back through the second flow path P2. Therefore, the sensation of the airflow is further improved. In particular, the velocity of the air flow returning through the second flow path P2 may be attenuated by the reflecting unit 3 and become smaller than the velocity of the air flow discharged from the discharge port 5. Therefore, conversely, as compared with the case where the air flow discharged from the discharge port 5 is directed to the reflecting portion 3 through the second flow path P2 and returns to the side of the discharge port 5 through the first flow path P1. It is possible to reduce the possibility of causing discomfort to a person (user) approaching the side of the first flow path P1.

Further, in the present embodiment, the discharge port 5 and the reflection portion 3 are separated from each other via the hollow portion 9 of the gap in the specific direction A1. Then, the air flow discharged from the discharge port 5 (outward air flow) and the air flow returning to the side of the discharge port 5 (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 each other between the discharge port 5 and the reflection portion 3. Therefore, it is possible to increase the possibility of giving a feeling of openness to the person (user) in the environmental space 100.

Further, in the present embodiment, the blower device 4 sucks the air flow returned from the reflection unit 3 to the side of the discharge port 5 from the intake port 6 and generates an air flow flowing along the specific direction A1, so that the environment space. The circulation of the airflow formed in 100 can be performed 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 portion 3 is formed between the first flow path P1 and the second flow path P2 so that the intermediate layer X1 having a relatively small air flow velocity is formed. The shape, the distance from the discharge port 5 to the first region 31 of the reflection unit 3, and the like are defined. The acoustic system 1 forms the intermediate layer X1 in the environmental space 100, and for the user who uses the acoustic system 1, the air enters the intermediate layer X1 after passing through the second flow path P2. You can experience the existence of the intermediate layer X1 separated by the flow. The intermediate layer X1 is provided as if it were isolated 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 air flow as a place of relaxation. Further, the cost can be reduced as compared with the case of partitioning by a physical partition wall, and the user can easily enter the intermediate layer X1 and is highly convenient.

Further, in the acoustic system 1 of the present embodiment, when the air flow discharged 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 air flow is taken in. It is configured so that it can be sucked in from the mouth 6 and circulated as a whole. Therefore, it can be expected to reduce the amount of additional elements used in the functional unit G1.

If the additional element is, for example, air purification, there is a high possibility that the air purified by the air purifying device will be discharged from the discharge port 5 and then refluxed and sucked in from the intake port 6 again. As a result, the life of the dust collecting filter, the deodorizing filter, etc. is extended.

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

Further, in the acoustic system 1 of the present embodiment, when the air flow discharged from the discharge port 5 returns to the side of the discharge port 5 (vertically downward) through the second flow path P2, the air flow functions as an air curtain. It is possible. In particular, the refluxing air flow can be released in a form that is less likely to be mixed with the air flow in the space inside the air curtain. As a result, for example, the additional element by the functional unit 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 is suppressed from leaking to the outside of the air curtain. In short, it becomes easier to sustain the situation where the space inside the air curtain is filled with additional elements.

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

(3.1) Modification 1
Hereinafter, the acoustic system 1A of the modification 1 will be described with reference to FIG. However, the components substantially common to the acoustic system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

As a result of diligent verification, the inventors of the present disclosure have determined that the shape of the reflecting portion 3 is larger than the height position of the discharging port 5 (distance from the discharging port 5 to the reflecting portion 3), the air volume of the blower 4, and the wind speed. , It was found that it is a factor that can greatly influence the formation of the air flow returning to the side of the discharge port 5.

The acoustic system 1A of the modification 1 is different from the acoustic system 1 of the basic example in that it includes a reflection unit 3 having a different shape from the reflection unit 3 of the basic example. The discharge port 5 in FIG. 5 is located at substantially the same height as the discharge port 5 in FIG. 1 in the basic example.

The reflection portion 3A of the modified example 1 has a main body portion 30A, a support portion 33, and a mounting portion 35 (the support portion 33 and the mounting portion 35 are omitted in FIG. 5). The main body 30A is formed in a substantially umbrella shape with an open lower surface. However, the main body portion 30 of the basic example has a bowl-shaped curved surface 300, while the main body portion 30A of the modified example 1 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 the 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 to which an air flow flowing along a specific direction A1 hits. The second region 32 is around the first region 31. The second region 32 flows along the air flow hit by the first region 31 and returns to the side of the discharge port 5. In the main body portion 30A of the present embodiment, the second region 32 is inclined straight so as to be closer to the discharge port 5 side as the distance from the first region 31 is along the horizontal direction.

FIG. 5 is a simulation result showing an air flow discharged from the discharge port 5 in the acoustic system 1A of the modification 1 and a state (streamline) in which the air flow hits the reflection unit 3A and returns to the side of the discharge port 5. be.

When the acoustic system 1A operates, 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 air flow discharged from the discharge port 5 flows toward the first region 31 of the reflection unit 3A through the first flow path P1. Then, the air flow that hits the first region 31 of the reflective portion 3A and spreads outward along the second region 32 of the reflective portion 3A returns to the side of the discharge port 5 (vertically downward) through the second flow path P2.

Here, unlike the second flow path P2 of the basic example, the second flow path P2 of the modified example 1 is diffused in a direction away from the ventilation system 2. Therefore, in the modified example 1, the volume of the intermediate layer X1 can be secured wider than that of the basic example. As a result, it is more likely that more users will be able to use the middle layer X1. However, in terms of "circulation" in which the air flow discharged from the discharge port 5 returns to the intake port 6 again, the modified example 1 may have lower circulation 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 the distance from the first region 31 is increased, a layer of air flow returning to the discharge port 5 side is further formed. It becomes easy to be done. Therefore, for the user who uses the acoustic system 1A, the experience of the airflow is higher in the basic example than in the modified example 1.

Further, another example of the modified example 1 ( acoustic system 1B) may include a reflecting unit 3B as shown in FIG. The main body portion 30B of the reflective portion 3B has a curved surface 300B curved in a bowl shape, similarly to the reflective portion 3 of the basic example. However, this curved surface 300B is different from the curved surface 300 of the basic example in that the tangential direction D1 at the opening edge portion is substantially parallel to the vertical direction. That is, the tangential direction 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 reflective portion 3B of FIG. 6 has higher circulation than the basic example and the example of FIG. Therefore, a layer of the air flow that is returned to the side of the discharge port 5 is more likely to be formed, and the sensation of the air flow can be improved. However, the volume of the intermediate layer X1 tends to be small, and the possibility that the user can experience the existence of the intermediate layer X1 separated by the air flow is reduced. 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 discharge port 5.

Yet another example of variant 1 ( acoustic system 1C) may include a reflector 3C, as shown in FIG. The main body portion 30C of the reflective portion 3C has a curved surface 300C curved in a bowl shape, similarly to the reflective portion 3 of the basic example. However, this curved surface 300C is different from the curved surface 300 of the basic example in that the tangential direction D2 at the opening edge portion is inclined so as to narrow inward toward the lower side.

The reflective portion 3C of FIG. 7 has higher circulation than the example of FIG. Therefore, a layer of the air flow that is returned to the side of the discharge port 5 is more likely to be formed, and the sensation of the air flow can be improved. However, the volume of the intermediate layer X1 tends to be smaller. 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 discharge port 5.

Yet another example of variant 1 ( acoustic system 1D) may include a reflector 3D, as shown in FIG. The main body portion 30D of the reflective portion 3D has a curved surface 300D curved in a bowl shape, similarly to the reflective portion 3 of the basic example. However, the 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. The tangential direction D3 at the opening edge of the curved surface 300D is substantially parallel to the vertical direction.

The reflective portion 3D of FIG. 8 also has relatively high circulation. Therefore, a layer of the air flow that is returned to the side of the discharge port 5 is more likely to be formed, and the sensation of the air flow can be improved. However, the volume of the intermediate layer X1 tends to be small. 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 discharge port 5.

(3.2) Modification 2
Hereinafter, the acoustic system 1E of the modification 2 will be described with reference to FIG. However, the components substantially common to the acoustic system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

In the acoustic system 1 of the basic example, the discharge port 5 is provided in the housing 7 configured to also function as a table. The acoustic system 1E of the modification 2 is different from the acoustic system 1 of the basic example in that the emission port 5 is directly provided on the floor surface 101.

Further, in the acoustic system 1 of the basic example, the reflecting portion 3 has a hanging type structure. The acoustic system 1E of the modified example 2 is different from the acoustic system 1 of the basic example in that it includes a reflecting portion 3E having an embedded structure.

The discharge port 5 of the modified example 2 is configured as, for example, a circular through hole penetrating the floor material in the thickness direction. In this case, the blower 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 in the vicinity of the discharge port 5 or may be installed on the wall surface 152.

The reflective portion 3E of the modification 2 is embedded and arranged in, for example, one of a plurality of square type ceiling materials 151 in the system ceiling 150. The reflecting portion 3E may be embedded and arranged over a plurality of (for example, four) ceiling materials 151. The reflective portion 3E is directly fixed to, for example, a hanging bolt of a ceiling slab behind the ceiling.

According to this modification 2, 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. .. In addition, parts (floor and housing) can be shared.

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

As yet another example of the modification 2, the acoustic system 1E may include a plurality of sets of one reflecting unit 3 and one emitting port 5 corresponding to each other as one set. Specifically, a plurality of reflecting portions 3E may be embedded and arranged in the system ceiling 150, and a plurality of discharging ports 5 may be provided on the floor surface 101 so as to have a one-to-one correspondence with the plurality of reflecting portions 3E. In this case, the number of the blower 4 and the control unit H1 does not necessarily have to be the same as the number of the discharge ports 5. For example, the air flow generated by one blower 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 control room or the like in the facility so that a plurality of blower devices 4 can be centrally managed. Similarly, in the basic example, the acoustic system 1 has one reflecting unit 3 and one emission port 5 as one set, and a plurality of sets thereof are provided, and one control unit H1 has a plurality of blower devices 4. May be configured to be centrally managed.

(3.3) Modification 3
Hereinafter, the acoustic system 1F of the modification 3 will be described with reference to FIG. However, the components substantially common to the acoustic system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

FIG. 10 is an external perspective view of the acoustic system 1F of the modified example 3. The sound system 1F of the modified example 3 is assumed to be installed in a hotel lobby or the like, and has a structure in consideration of convenience and design. The housing 7F of the ventilation system 2 of the sound 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 a discharge port 5. The figurine 75 has an opening at the bottom, and the air flow 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. Further, one or a plurality of lobby sofas 301 are installed so as to surround the housing 7F.

The reflective portion 3F of the modified example 3 has a cylindrical main body portion 30F having an open lower surface. The reflective portion 3F does not have the support 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 of the opening surface of the main body 30F. Reflective portions 3F having various dimensions and shapes are installed according to the number and shape of the lobby sofa 301.

By providing the air flow by the sound system 1F in the lobby of the hotel or the like in this way, it is possible to provide a local space different from the surroundings in the environmental space 100 without being blocked by a physical partition wall. Further, by appropriately combining light, sound, and additional elements (scent, etc.) with the air flow, it can be provided as a more comfortable place for relaxation.

FIG. 11 is an external perspective view of another example ( acoustic system 1G) of the modified example 3. The acoustic system 1G of FIG. 11 is assumed to be installed in a waiting room or the like in a hospital, and has a structure in consideration of convenience and sterilization. The ventilation system 2 of the sound 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 4 housed in the pole-shaped 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 reflective portion 3G of FIG. 11 has an umbrella-shaped main body portion 30G having an open lower surface. 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 reflective portion 3G of FIG. 11 has a relatively large size so that it can be used by as many users (patients) as possible.

In this way, by providing an air flow by the acoustic system 1G in a waiting room or the like in a hospital, it is possible to provide a local space different from the surroundings in the environmental space 100 without being blocked by a physical partition wall. .. Further, the air flow passing through the second flow path P2 is effective as a barrier function, and the risk of nosocomial infection can be reduced. Further, by appropriately combining an additional element (air purification: hypochlorous acid, etc.) with the air flow, it can be provided as a cleaner place.

(3.4) Modification 4
Hereinafter, the acoustic system 1H of the modified example 4 will be described with reference to FIG. However, the components substantially common to the acoustic system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

The acoustic system 1H of the modification 4 is different from the acoustic system 1 of the basic example in that the emission port 5 is arranged on one surface of a member constituting the chair 303. Since the reflection unit 3 of the acoustic system 1H is common to the basic example, the description thereof will be omitted.

The acoustic system 1H of the modification 4 has a housing 7H that functions as a chair 303. The housing 7H has a hollow substantially rectangular parallelepiped seat portion 76 and a prismatic backrest 77 provided in the center of the upper surface (seat surface 760) of the seat portion 76. The blower device 4 and the like are housed in the seat portion 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 timbers 761 are assembled so as to be lined up at predetermined intervals, and the gap between the adjacent square timbers 761 becomes the intake port 6.

According to this modification 4, 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. .. In addition, parts (chair and housing) can be shared.

(3.5) Modification 5
Hereinafter, the acoustic system 1I of the modified example 5 will be described with reference to FIG. However, the components substantially common to the acoustic system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

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

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

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

Unlike the support portion 33 of the reflection portion 3 of the basic example, the support portion 33 of the reflection 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 33 of the reflective 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 33 is attached to the inner apex of the main body portion 30, and the second end (lower end) of the support portion 33 is fixed to the pedestal B1. However, here, the support portion 33 of the reflection portion 3H is realized by the guide portion 8. In other words, the guide portion 8 supports the reflective portion 3H (the main body portion 30).

The housing 7I of the ventilation system 2 of the sound system 1I also serves as a pedestal B1 on which (a plurality of) people can sit. That is, the acoustic system 1I includes a 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 central axis of the pedestal B1 substantially coincides with the central axis of the support portion 33 corresponding to the handle portion of the umbrella (main body portion 30). A blower device 4 and the like are housed in the pedestal B1 (housing 7I). The intake port 6 is arranged on the outer peripheral surface of the pedestal B1 (shown at two locations in FIG. 13). Here, the outer diameter of the main body portion 30 of the umbrella-shaped reflective portion 3H is set to be larger than the outer diameter of the pedestal B1. As a result, the air flow that hits the reflective portion 3H is made easy to return.

The guide unit 8 is configured to guide the air flow flowing to the reflection unit 3H along the specific direction A1. The guide portion 8 is fixed to the pedestal B1. The guide portion 8 has a partition portion 80 (one or a plurality of portions) that divides the environmental space 100 into two or more along the circumferential direction D4 of the specific direction A1. Here, as an example, the environment space 100 is divided into four by having a total of four partition portions 80 (only three are shown in FIG. 13). Each partition 80 has a long plate shape along a specific direction A1. Here, the four plate-shaped partition portions 80 guide the air flow flowing to the reflective portion 3H along the specific direction A1.

The four partition portions 80 project from the pedestal B1 along a specific direction A1. Here, the four partition portions 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 regions on the upper surface of the pedestal B1 is fan-shaped 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 area. That is, here, four people are set to be able to 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 of each partition 80 (the edge opposite to the central axis) is the intermediate edge 800 extending in the vertical direction, the first edge 801 continuous from the lower part of the intermediate edge 800, and the 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 when viewed along the thickness direction of each partition portion 80. 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 reflective portion 3H. The four partition portions 80 function as a plurality of bone portions that stably hold the umbrella-shaped reflective portion 3H by contacting the inner surface of the reflective portion 3H at each third edge 803.

Further, the guide portion 8 further has a backrest portion 81 protruding from the upper surface of the pedestal B1 along a specific direction A1 between two partition portions 80 adjacent to each other of the four partition portions 80. A total of four backrest portions 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 area of the pedestal B1 can relax by using the backrest portion 81.

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

According to the acoustic system 1I of the modification 5, the stability of the returning air flow can be further improved by providing the guide portion 8.

Further, since the guide portion 8 has the partition portion 80, it is possible to improve the sensation of the air flow individually in each of the plurality of spaces divided by the partition portion 80. Further, since the partition portion 80 protrudes from the pedestal B1 along a specific direction A1, each person can sit on the pedestal B1 and experience the air flow in each space divided by the partition portion 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.

Then, in the acoustic system 1I of the modification 5, each person sits in the area between the two adjacent partition portions 80 on the upper surface of the pedestal B1 in the space surrounded by the two partition portions 80. Then, you can experience the airflow discharged from the corresponding discharge port 5. In particular, by being partitioned by the partition portion 80, a certain distance from the person sitting sideways is maintained, and there is a high possibility that the line of sight from the person next to the person is blocked. As a result, it is possible to give a sense of security to each person who uses the sound system 1I.

Further, the acoustic system 1I of the modified example 5 does not require a portion for suspending the main body 30 from the side of the ceiling surface, and the installation and introduction of the acoustic system 1I can be easily performed even in a space where the ceiling is a stairwell, for example.

(3.6) Modification 6
Hereinafter, the acoustic system 1J of the modification 6 will be described with reference to FIG. However, the components substantially common to the acoustic system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

The acoustic system 1J of the modification 6 is different from the acoustic system 1 of the basic example in that it includes a reflection portion 3I having a main body portion 30 having a substantially semi-cylindrical shape (kamaboko shape).

FIG. 14 is an external perspective view of the acoustic system 1J of the modified example 6. In the sound system 1J of the modification 6, for example, a plurality of (six here) chairs 401 and a work desk 402 (long desk) are installed so that a plurality of people can use and study or work. It is expected to be applied to the workspace.

The reflection portion 3I of the acoustic system 1J of the modification 6 has a main body portion 30 and one or a plurality of (here, a pair) of support portions 33. The main body portion 30 is long along one direction. The main body 30 has a substantially semi-cylindrical shape in which both ends and the lower surface in the longitudinal direction are open. The longitudinal direction of the main body 30 is along the longitudinal direction of the work desk 402. In other words, the axial direction of the substantially semi-cylindrical main body 30 is along the longitudinal direction of the work desk 402. The main body portion 30 is a plate-shaped portion 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 30 from the side of the ceiling surface.

The housing 7J of the ventilation system 2 of the sound system 1J also serves as a work desk 402. The work desk 402 includes a rectangular parallelepiped base 403 that is long along the axial direction of the main body 30, and a flat plate-shaped top plate 404 that is placed on the base 403. Each person can sit on a chair 401 and place a notebook computer or the like on the top plate 404 to carry out the work.

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

In the acoustic system 1J, the discharge port 5 is composed of an opening provided in the central portion 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.

This acoustic system 1J realizes a configuration in which the air flow that hits the substantially semi-cylindrical reflecting portion 3I easily returns. That is, the air flow discharged from the discharge port 5 hits the inner surface of the substantially semi-cylindrical main body portion 30 and recirculates 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 the modification 6, the acoustic system 1K as shown in FIG. 15 may be provided. In the acoustic system 1K, three chairs 401 are arranged along the axial direction of the main body portion 30 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. On the other hand, the second side portion 402B, which is the other of both side portions in the width direction of the work desk 402, is in a state close to the wall 405 which is a building material such as a building.

Further, the reflective portion 3J of the acoustic system 1K has a main body portion 30 which is only one side (right one side in FIG. 14) of the main body portion 30 of the above-mentioned reflective portion 3I in the width direction.

In this acoustic system 1K, each person sitting on the chair 401 works in a form facing the wall 405. Even in this configuration, the work can be performed while experiencing the air flow. In particular, the wall 405 functions as the "guide portion 8" described in the modified example 5. That is, the wall 405 can guide the air flow flowing to the reflecting portion 3J along the specific direction A1. As a result, the stability of the recirculated air flow can be further improved.

(3.7) Other Modifications The blower 4, the light projecting unit E1, the speaker unit F1, and the functional unit G1 in the basic example are not essential components in the acoustic system 1, and the acoustic system 1 is among these. It does not have to have at least one. Further, the intake port 6 in the basic example is not an essential component in the acoustic system 1, and the acoustic system 1 does not have to include the intake port 6.

In the basic example, the specific direction A1 is parallel to the vertical direction and is vertically upward, but may be vertically downward. Alternatively, the specific direction A1 may be a direction that intersects the vertical direction. However, if the specific direction A1 is at least parallel to the vertical direction, it is possible to easily form an air flow that returns to the side of the discharge port 5.

In the basic example, both the light projecting unit E1 and the lighting unit E2 are provided, but only one of these may be provided. Further, the object to which the mounting portion 35 is mounted may be a rail member having no power feeding function (conductor portion) in addition to the wiring duct 200 of the basic example.

In the basic example, the reflective portion 3 is configured to hang the main body portion 30 from the side of the ceiling surface via the support portion 33. However, like the handle (axis) of the umbrella, the first end of the support 33 is attached to the inner apex of the main body 30 (the center of the first region 31), 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 (similar to the basic example), and the intermediate 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 reflective portion 3 has an umbrella shape as a whole, but it may have a curved surface 300 inside thereof. For example, the reflective portion 3 is formed in a block shape as a whole, and only the lower surface thereof has a curved surface 300. It may be dented in.

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

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

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

(4) Summary As described above, the acoustic system (1, 1A to 1K) according to the first aspect includes a discharge port (5) and a reflection unit (3, 3A to 3J). The discharge port (5) discharges 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 so as to face the discharge port (5) in a specific direction (A1), and are hit by an air flow flowing along the specific direction (A1). The reflecting portions (3, 3A to 3J) are configured to return the hit air flow to the discharge port (5) side in the environmental space (100). According to the first aspect, it is possible to improve the sensation of the air flow formed in the environmental space (100).

Regarding the acoustic system (1, 1A to 1K) according to the second aspect, in the first aspect, the reflecting unit (3, 3A to 3J) includes the first region (31), the second region (32), and the second region (32). It is preferable to have. The first region (31) is hit by an air flow flowing along a specific direction (A1). The second region (32) is around the first region (31), and the air flow hit by the first region (31) flows along the flow and is returned to the side of the discharge port (5).
