By the way, in such a conventional blower, when a downward flow is directly applied to a table user in winter in Japan, the user feels uncomfortable due to a draft feeling (excessive cold feeling or warm feeling). There is a problem. For this reason, it is necessary to change the airflow direction of the downward flow that blows toward the user depending on the season. It requires the work of exchanging with a different shape, and has a problem that it is not convenient for the user.

Therefore, the present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an airflow environment system capable of switching the airflow direction at the end of the reflecting portion when the airflow is returned to the environmental space. And.

Then, in order to achieve this object, the airflow environment system according to the present invention has an outlet that discharges an air flow flowing in at least a specific direction into the environmental space and a discharge port that faces the discharge port in a specific direction. It is provided with a reflecting portion that is arranged in the above and is hit by an air flow flowing along a specific direction, and a wind direction changing portion that returns the air flow that hits the reflecting portion to the discharge port side. The wind direction changing unit is characterized in that the airflow direction in which the recirculating air flow flows can be switched between the first recirculation direction and the second recirculation direction different from the first recirculation direction. , This achieves the purpose of the description.

According to the present invention, it is possible to obtain an airflow environment system capable of switching the airflow direction at the end of the reflecting portion when the airflow is returned to the environmental space.

FIG. 2 is an external perspective view of the airflow environment system as viewed from below.

FIG. 5 is a partial cross-sectional view showing the first state of the wind direction changing portion in the airflow environment system. FIG. 6 is a partial cross-sectional view showing a second state of the wind direction changing portion in the airflow environment system. FIG. 7 is a block diagram showing a configuration of a control unit in an airflow environment system. FIG. 8 is a cross-sectional view for explaining the airflow formed by the wind direction changing portion in the first state in the airflow environment system. FIG. 9 is a cross-sectional view for explaining the airflow formed by the wind direction changing portion in the second state in the airflow environment system. FIG. 10 is a cross-sectional view for explaining an air flow formed in the air flow environment system according to the second embodiment of the present invention. FIG. 11 is an external perspective view showing the structure of a conventional blower.

The airflow environment system according to the present invention is arranged so as to face a discharge port that discharges an air flow flowing in at least a specific direction into an environmental space and a discharge port in a specific direction, and along a specific direction. It is provided with a reflecting portion to which the flowing air flow hits, and a wind direction changing portion for returning the air flow hitting the reflecting portion to the discharge port side. Then, the wind direction changing unit is configured to be able to switch the airflow direction in which the recirculating air flow flows between the first recirculation direction and the second recirculation direction different from the first recirculation direction.

According to such a configuration, when the airflow is returned to the environmental space, the airflow direction can be automatically switched between the first return direction and the second return direction by the wind direction changing portion at the end portion of the reflecting portion. Therefore, it is possible to reduce the draft feeling (discomfort) due to the airflow blown toward the user without the user having to replace the reflective portion with one having a different shape as in the conventional airflow environment system.

Further, in the airflow environment system according to the present invention, the reflecting portion is located in the first region where the air flow flowing along a specific direction hits and around the first region so that the airflow hit in the first region follows. It is preferable to have a second region that flows into the air and reaches the wind direction changing portion. By doing so, an air flow flowing from the first region to the wind direction changing portion along the reflecting portion is formed, so that a layer of air flow returning from the wind direction changing portion to the discharge port side is likely to be formed. Therefore, there is a high possibility that the environmental space is divided into two spaces by the layer. Therefore, the sensation of airflow is improved.

Further, in the airflow environment system according to the present invention, in the environmental space, a first flow path in which the air flow discharged from the discharge port flows toward the reflection portion and a second flow path in which the air flow returned by the wind direction changing portion flows. And is formed, and when viewed along a specific direction, the second flow path is preferably formed so as to surround the first flow path. By doing so, the user who approaches the side of the first flow path is more likely to come into contact with the layer of the air flow that returns through the second flow path. Therefore, the sensation of airflow is improved. In particular, the velocity of the airflow returning through the second flow path may be attenuated by the reflecting portion and the wind direction changing portion, and may be smaller than the velocity of the airflow discharged from the discharge port. Therefore, conversely, the air flow discharged from the discharge port is directed to the reflection portion through the second flow path and returns to the side of the first flow path as compared with the case where the air flow is returned to the side of the discharge port through the first flow path. It is possible to reduce the possibility of causing discomfort to an approaching user.

Further, in the airflow environment system according to the present invention, it is preferable that the wind direction changing section includes a first wind direction changing section and a second wind direction changing section different from the first wind direction changing section. By doing so, in the environmental space, a space through which the air flow returning through the first wind direction changing portion flows and a space in which the air flow returning through the second wind direction changing portion flows are independently formed. Can be done. Therefore, it is possible to blow an air flow suitable for the user for each space divided by the wind direction changing unit, and it is possible to reduce the possibility of causing discomfort to the user.

Further, the airflow environment system according to the present invention further includes a pedestal on which the user can sit. The first reflux direction is the direction in which the refluxing air flow is directed toward the feet of the user sitting on the pedestal, and the second reflux direction is the direction in which the refluxing air flow is directed toward the feet of the user sitting on the pedestal. It is preferable that the direction is such that the air flows toward. By doing so, if the user sitting on the pedestal feels uncomfortable with the air flow that recirculates in the second recirculation direction, simply switch to the air flow that recirculates in the first recirculation direction by the wind direction changing unit. It is possible to reduce the amount of airflow that directly hits the person. Therefore, the draft feeling due to the air flow felt by the user can be easily reduced.

Further, in the airflow environment system according to the present invention, the discharge port and the reflection part are separated from each other through the hollow part of the void in a specific direction, and are returned by the air flow and the wind direction changing part discharged from the discharge port. The air flow preferably flows through the hollow portion. By doing so, there is no obstacle that separates the air flow flowing along the specific direction and the air flow returning to the side of the discharge port from each other. Therefore, it is possible to increase the possibility of giving a feeling of openness to the user in the environmental space.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are examples that embody the present invention, and do not limit the technical scope of the present invention. In addition, the same parts are designated by the same reference numerals throughout the drawings, and the second and subsequent explanations are omitted.

(Embodiment 1)
First, the outline of the airflow environment system 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is an external perspective view of the airflow environment system 1 according to the first embodiment of the present invention. FIG. 2 is an external perspective view of the airflow environment system 1 as viewed from below. FIG. 3 is a block diagram showing the configuration of the ventilation system 7 in the airflow environment system 1.

In the following, the direction perpendicular to (orthogonal) with respect to the horizontal plane (floor surface 11) in the state where the blower unit 2 is installed on the floor surface 11 as shown in FIG. 1 is referred to as the "vertical direction". , This direction is not intended to limit the direction of use of the blower unit 2.

The airflow environment system 1 is, for example, a system configured to form an airflow in the environmental space 10 in the facility. The "environmental space" in the present invention is not limited to the space inside the facility, but may be a space outside the facility (outdoor).

As shown in FIGS. 1 and 2, the airflow environment system 1 includes a blower unit 2 and a reflection unit 3. The blower unit 2 is installed on the floor surface 11 in the environmental space 10, and discharges an air flow flowing along at least a specific direction A1 to the environmental space 10. The reflection unit 3 is installed at a position facing the blower unit 2 in a specific direction A1 on the ceiling surface (not shown) in the environmental space 10, and is hit by an air flow flowing along the specific direction A1. Then, the reflection unit 3 is configured to return the hit air flow to the side of the blower unit 2 in the environmental space 10 (see the return direction A3 in FIG. 1). Here, as an example of the "specific direction" in the present invention, it is assumed that the "specific direction A1" of the present embodiment is vertically upward. Therefore, the reflection unit 3 is arranged directly above the blower unit 2.

Specifically, the blower unit 2 will be described.

As shown in FIGS. 1 and 2, the blower unit 2 includes a housing 4, a discharge port 5, an intake port 6, and a blower system 7.

The housing 4 is a member that constitutes the outer frame of the blower unit 2, and is configured to function as a chair (a pedestal on which the user can sit) as a whole. Further, the housing 4 is configured to accommodate or hold the ventilation system 7 inside. Further, the housing 4 has a discharge port 5 formed on the central upper surface thereof and an intake port 6 formed on the outer peripheral side surface thereof. The material of the housing 4 is not particularly limited, but it is desirable that the housing 4 has dimensions and durability sufficient to function as a chair.

Further, the housing 4 includes an operation panel 4a (see FIG. 7) that can be used as an input device by the user when operating the operating state of the airflow environment system 1. The operation panel 4a is used as an input means to the control unit 12 (see FIG. 7) described later. The operation panel 4a may be a liquid crystal screen installed in the housing 4, or may be a remote controller or the like that exists in the environment space 10 and can wirelessly communicate with the control unit 12.

The discharge port 5 is arranged on the central upper surface of the housing 4 (the surface on the side in the specific direction A1). The discharge port 5 is configured to communicate with the ventilation system 7 through a duct (not shown), and the air flow blown from the ventilation system 7 is used as an air flow flowing along at least a specific direction A1 in the environment. Release into space 10.

The intake port 6 is arranged on the outer peripheral side surface of the housing 4 (circumferential direction in the specific direction A1), and is composed of, for example, a plurality of slit-shaped holes that are elongated in the vertical direction. The intake port 6 is configured to communicate with the ventilation system 7 via a duct (not shown), and as the ventilation system 7 blows air, air is introduced from the outside to the inside of the housing 4 along the intake direction B1. Inhale.

As described above, the ventilation system 7 is configured to be housed or held inside the housing 4. Further, the ventilation system 7 is communicated with the discharge port 5 and the intake port 6 via a duct inside the housing 4. Then, the air in the environmental space 10 is supplied to the ventilation system 7 from the intake port 6 and discharged to the environmental space 10 from the discharge port 5.

Specifically, as shown in FIG. 3, the ventilation system 7 includes a ventilation device 7a and a functional unit 7b.

The blower 7a sucks the air in the environmental space 10 from the intake port 6 under the control of the control unit 12 (see FIG. 7), and generates an air flow flowing along a specific direction A1 (here, vertically upward). , It is configured to be sent to the discharge port 5. The blower 7a 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 7a is housed in the housing 4 with its front surface facing upward, and is connected to the discharge port 5 by communicating with the discharge port 5 by a duct. The air flow generated by the blower 7a is discharged from the discharge port 5 as an air flow flowing along the specific direction A1 as it is.

Here, the blower device 7a may be able to adjust the rotation speed of the motor and appropriately change the air volume by, for example, inverter control. At this time, the operation panel 4a is provided with a volume for adjusting the air volume, and the user appropriately adjusts the air volume of the air flow device 7a at the installation site of the air flow environment system 1, that is, the environmental space 10.

Further, the air flow generated by the blower device 7a is not limited to being discharged from the discharge port 5 as it is, and for example, a branch chamber for merging the air flows generated by the plurality of blower devices 7a and a duct connecting them are provided. It may be discharged from the discharge port 5 through. The materials of the blower 7a, the branch chamber, and the duct are not particularly limited, but the durability is affected by the additional element given to the air flow discharged from the discharge port 5 to the environmental space 10 by the functional unit 7b described later. It is desirable not to receive it.

The functional unit 7b is configured to add an additional element to the air flow discharged from the discharge port 5 to the environmental space 10. Additional elements include at least one of scent, air purification, and temperature changes.

When the additional element contains a scent, the functional portion 7b is housed in the housing 4. The additional element has, for example, a scent presenting device containing a fragrance. The scent vaporized from the fragrance mixes with the air flow flowing from the blower 7a to the discharge port 5. As a result, it is possible to provide the user in the environmental space 10 with high-quality scented air.

If the additional element includes air purification, functional unit 7b has, for example, an air purifier. The air purifier is housed in the housing 4. The air purifier has a dust collecting filter for collecting 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 7a. As a result, purified air can be provided to the user in the environmental space 10.

If the additional element includes air purification, the functional unit 7b may have, for example, a space sterilization deodorizer. The space sterilization deodorizer is housed in the housing 4. The space sterilization deodorizer is configured to generate hypochlorous acid and mix it with the air flow generated by the blower 7a. The air stream containing hypochlorous acid is discharged upward from the discharge port 5 to sterilize the environmental space 10. As a result, purified air can be provided to the user in the environmental space 10.

If the additional element includes a temperature change, the functional unit 7b has, for example, an air conditioner. The air conditioner has a compressor, and the cold air or warm air generated by the air conditioner is discharged upward from the discharge port 5 as an air flow by the blower 7a. As a result, it is possible to provide the user in the environmental space 10 with air having a comfortable temperature.

When the functional unit 7b has the above-mentioned air purifier, space sterilization deodorizer, and air conditioner, the power of these devices can be turned on / off and various parameters can be adjusted by, for example, operating the operation panel 4a. It is feasible. The control unit 12 (see FIG. 7), which will be described later, may intensively control the functional unit 7b. The operation of the functional unit 7b may be controlled under the control of the control unit 12 so as to be interlocked with the operation of the blower device 7a.

By providing the functional unit 7b to the ventilation system 7 in this way, an additional element can be easily added to the air flow.

Next, the reflection unit 3 will be described with reference to FIGS. 1, 2, and 4. FIG. 4 is an enlarged schematic view of the attachment portion of the wind direction changing portion 9 in the airflow environment system 1.

As shown in FIGS. 1 and 2, the reflection unit 3 includes a reflection unit 8 and a wind direction changing unit 9.

The reflective portion 8 has a cylindrical shape with an open lower surface, and is directly attached to the ceiling surface. The lower surface of the reflecting portion 8 (the surface facing the discharge port 5) has a curved surface 8a (specifically, a curved bowl shape) in which the central portion thereof is recessed. The reflection unit 8 is located directly above the discharge port 5 of the blower unit 2, and is arranged so that the blower unit 2 generally fits within the projection area when the opening surface of the reflection unit 8 is projected onto the floor surface 11. NS.

In the reflection unit 8, when the airflow environment system 1 (blower system 7) is operated, the air flow discharged from the discharge port 5 (the air flow flowing along the specific direction A1) hits the curved surface 8a of the reflection unit 8. .. Then, the reflecting portion 8 circulates the hit air flow along the curved surface 8a to the side of the wind direction changing portion 9 (the end side of the reflecting portion 8) (reflection direction A2 in FIG. 2).

On the other hand, as shown in FIG. 2, the wind direction changing portions 9 are installed at a plurality of locations along the circumferential direction of the reflecting portion 8 at the outer peripheral end portion of the reflecting portion 8. The wind direction changing unit 9 is configured to return the air flow (reflection direction A2) reflected by the reflection unit 8 to the discharge port 5 side in the environmental space 10 (reflux direction A3).

Specifically, as shown in FIG. 4, each of the plurality of wind direction changing units 9 is a servomotor 9a that rotates the wind direction changing unit 9 within a predetermined movable range, and a servomotor 9a that rotates the servomotor 9a to the wind direction changing unit 9. It is configured to include a transmission gear 9b. As a result, the wind direction changing section 9 is driven by the servomotor 9a via the gear 9b, and the air flow returning from the wind direction changing section 9 to the discharge port 5 side flows in the recirculation direction A3 (at the tip of the wind direction changing section 9). The tangential direction (corresponding to D1) is changed within a predetermined range.

Subsequently, with reference to FIGS. 5 and 6, the recirculation direction A3 of the air flow recirculating from the wind direction changing portion 9 to the discharge port 5 side will be described. Here, the first state (first tangential direction D11) in which the tangential direction D1 corresponding to the reflux direction A3 is inclined to the outside of the reflecting portion 8 with respect to the vertical direction, and inside the reflecting portion 8 with respect to the vertical direction. Two states, the second state of inclination (second tangential direction D12), will be illustrated. FIG. 5 is a partial cross-sectional view showing the first state of the wind direction changing portion 9 in the airflow environment system 1. FIG. 6 is a partial cross-sectional view showing a second state of the wind direction changing portion 9 in the airflow environment system 1. The reflux direction A3, the first reflux direction A31, and the second reflux direction A32 are assumed to be the directions in which the air flow immediately after passing through the wind direction changing portion 9.

In the first state, as shown in FIG. 5, by driving the servomotor 9a, the tangential direction D1 of the wind direction changing portion 9 is inclined so as to expand outward with respect to the vertical direction, and the first tangential direction D11. The wind direction changing portion 9 is rotated so as to be. As a result, in the wind direction changing section 9 in the first state, the air flow flowing in the reflecting direction A2 along the reflecting section 8 flows toward the first reflux direction A31 via the wind direction changing section 9.

On the other hand, in the second state, as shown in FIG. 6, by driving the servomotor 9a, the tangential direction D1 of the wind direction changing portion 9 is inclined so as to expand inward with respect to the vertical direction, and the second tangential direction. The wind direction changing portion 9 is rotated so as to be D12. As a result, in the wind direction changing section 9 in the second state, the air flow flowing in the reflecting direction A2 along the reflecting section 8 flows toward the second reflux direction A32 via the wind direction changing section 9.

Then, the wind direction changing unit 9 simply drives the servomotor 9a to switch the state of the wind direction changing unit 9 to the first state or the second state, and the air flow returning from the wind direction changing unit 9 to the discharge port 5 side is generated. The flowing reflux direction A3 can be switched to the first reflux direction A31 or the second reflux direction A32.

Next, the control unit 12 in the airflow environment system 1 will be described with reference to FIG. 7. FIG. 7 is a block diagram showing the configuration of the control unit 12 in the airflow environment system 1.

The control unit 12 controls the operating operation of the servomotor 9a used to drive the ventilation system 7 (blower device 7a, functional unit 7b) and the wind direction changing unit 9. The control unit 12 may be housed inside the housing 4, or may be housed inside the reflection unit 8. Further, the control unit 12 performs communication with the operation panel 4a, communication with the ventilation system 7, and communication with the servomotor 9a wirelessly or by wire.

Specifically, as shown in FIG. 7, the control unit 12 includes an input unit 12a, a processing unit 12b, an output unit 12c, a storage unit 12d, and a timekeeping unit 12e.

The input unit 12a provides information on turning on / off the power of the ventilation system 7, air volume setting, and additional element setting by the user's operation from the operation panel 4a installed in the housing 4, and the setting angle of the wind direction changing unit 9. Receives information about the above and outputs it to the processing unit 12b. Here, the information regarding the set angle corresponds to the information regarding the tangential direction D1 (first tangential direction D11, second tangential direction D12) in the wind direction changing unit 9.

The processing unit 12b specifies the blower output information (information on the on / off of the operation operation and the rotation speed) for the blower device 7a based on the information related to the air volume setting of the blower system 7 output from the input unit 12a, and the output unit 12c Output to.

Here, when the air volume of the blower 7a is changed periodically, the processing unit 12b has the time information output from the time measuring unit 12e and the information regarding the periodic change output from the storage unit 12d (air volume and time interval). ) And the calculation program, the blower output information (information on the on / off of the operation operation and the rotation speed) for the blower device 7a is specified and output to the output unit 12c.

Further, the processing unit 12b specifies the operation operation information (information regarding on / off of the operation operation, etc.) for the function unit 7b based on the information regarding the additional element setting of the ventilation system 7 output from the input unit 12a, and the output unit 12b. Output to 12c.

Here, when the operation operation of the functional unit 7b is changed periodically, the processing unit 12b uses the time information output from the time measuring unit 12e, the information regarding the periodic change output from the storage unit 12d, and the calculation unit. Using a program, the driving operation information (information regarding on / off of the driving operation, etc.) for the functional unit 7b is specified and output to the output unit 12c.

Further, the processing unit 12b drives, for example, the servomotor 9a to change the state of the wind direction changing unit 9 to the first state or the second state based on the information regarding the set angle of the wind direction changing unit 9 output from the input unit 12a. Identify information to change. Specifically, the processing unit 12b uses the current angle information of the servomotor 9a output from the storage unit 12d, the information regarding the set angle of the servomotor 9a, and the angle output information with respect to the servomotor 9a by using the calculation program. (Information on on / off of the operation of the servomotor 9a and the number of rotations) is specified and output to the output unit 12c.

The calculation program executed by the processing unit 12b may be a program recorded on a recording medium such as a memory card and provided, or a program provided through a telecommunication line such as the Internet may be used. May be good.

The storage unit 12d stores the operation operation information of the blower device 7a, the operation operation information of the function unit 7b, the angle output information of the servomotor 9a, and the calculation parameters, and the current blower device 7a output from the processing unit 12b. The operation operation information of the above, the operation operation information of the functional unit 7b, and the angle output information of the current servomotor 9a are received and stored. Each of the stored information is output from the storage unit 12d to the processing unit 12b in response to a request from the processing unit 12b.

The output unit 12c outputs information regarding the operating operation of the ventilation system 7 (blower device 7a, functional unit 7b) and the servomotor 9a received from the processing unit 12b to the ventilation system 7 and the servomotor 9a, respectively. Then, the ventilation system 7 executes the operation according to the information regarding the operation operation output from the output unit 12c. Further, the servomotor 9a executes an operation according to the angle output information output from the output unit 12c.

Subsequently, the air flow formed in the environmental space 10 by the airflow environment system 1 will be described in detail with reference to FIGS. 8 and 9. FIG. 8 is a cross-sectional view for explaining the airflow formed by the wind direction changing portion 9 in the first state in the airflow environment system 1. FIG. 9 is a cross-sectional view for explaining the airflow formed by the wind direction changing portion 9 in the second state in the airflow environment system 1.

First, the common part in the airflow environment system 1 in which the wind direction changing portion 9 is in the first state or the second state will be additionally described.

As described above, the reflecting portion 8 has a curved surface 8a whose central portion is recessed on the surface facing the discharge port 5. More specifically, as shown in FIGS. 8 and 9, the reflecting unit 8 has a first region 81 and a second region 82 on the curved surface 8a.

The first region 81 is a central region including the apex of the curved surface 8a, and is a region hit by an air flow flowing along a specific direction A1.

The second region 82 is around the first region 81. In other words, when the curved surface 8a is viewed from the front (from the lower side), the second region 82 is a donut-shaped region. The second region 82 is a region in which the air flow that hits the first region 81 flows along and returns to the side of the discharge port 5. In the reflection unit 8 of the present embodiment, the second region 82 moves toward the discharge port 5 as the distance from the first region 81 increases along the direction orthogonal to the specific direction A1 (horizontal direction in the present embodiment). It is curved to approach.

In the reflection unit 8, when the airflow environment system 1 (blower system 7) is operated, the air flow discharged from the discharge port 5 with respect to the first region 81 of the curved surface 8a of the reflection unit 8 (flows along a specific direction A1). Air flow) hits. Then, the air flow that hits the first region 81 of the curved surface 8a is reflected and flows toward the side of the wind direction changing portion 9 (reflection direction A2) along the second region 82 of the curved surface 8a. Further, the air flow flowing in the reflection direction A2 is returned to the side of the discharge port 5 (reflux direction A3) by the wind direction changing portion 9 located at the outer peripheral end portion of the reflection portion 8.

Then, when a series of airflow flows are formed by the airflow environment system 1, the first flow path P1 and the second flow path P2 are formed in the environment space 10. The first flow path P1 is a flow path in which the air flow discharged from the discharge port 5 flows toward the reflection portion 8, and the second flow path P2 is a flow path in which the air flow hitting the reflection portion 8 moves toward the discharge port 5. It is a flow path that returns.

That is, the air flow discharged from the discharge port 5 flows toward the first region 81 of the reflection unit 8 through the first flow path P1. Then, the air flow whose flow direction has been changed by the wind direction changing unit 9 returns to the side of the discharge port 5 (vertically downward) through the second flow path P2. When viewed along a specific direction A1 (for example, from above), the second flow path P2 is formed so as to surround the first flow path P1.

Further, the discharge port 5 and the reflection portion 8 are separated from each other via the hollow portion 13 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 13. 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 8. Therefore, it is possible to increase the possibility of giving a feeling of openness to the person (user) in the environmental space 10.

Next, the airflow environment system 1 in which the wind direction changing unit 9 is in the first state will be described.

When the wind direction changing portion 9 is in the first state, as shown in FIG. 8, the first return direction A31 is seated on the pedestal of the housing 4 when the user is seated on the pedestal of the housing 4. The direction is such that the air flow flows toward the user's feet. That is, in the first state, 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 recirculated air flow sits on the pedestal of the housing 4. The air is blown toward the feet of the user. As a result, the amount of airflow that directly hits the user can be reduced, so that the draft feeling due to the airflow felt by the user can be reduced.

Further, in the first state, 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 discharged to the intake port 6 (in the intake port 6 (vertically downward). It is configured so that it can be sucked in from (see FIG. 1) and circulated as a whole. Therefore, it can be expected to reduce the amount of additional elements used in the functional unit 7b.

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

Further, if the additional element is, for example, a temperature change, there is a 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. It gets higher. 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 first state, 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 can function as an air curtain. Is. 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, the additional element by the functional unit 7b included 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.

Next, the airflow environment system 1 in which the wind direction changing unit 9 is in the second state will be described.

When the wind direction changing portion 9 is in the second state, as shown in FIG. 9, the second return direction A32 is seated on the pedestal of the housing 4 when the user is seated on the pedestal of the housing 4. The direction is such that the air flow flows toward the user's head. That is, in the second state, 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 returning air flow sits on the pedestal of the housing 4. The air is blown toward the user's head. As a result, in the second state, the air flow directly hits the user, so that the user can effectively feel the air flow (cold air or hot air).

Then, in the airflow environment system 1 according to the present embodiment, the wind direction changing unit 9 can switch between the first state (see FIG. 8) and the second state (see FIG. 9). As a result, an air flow suitable for the user can be blown, and the possibility of causing discomfort to the user can be reduced.

As described above, according to the airflow environment system 1 according to the first embodiment, the following effects can be enjoyed.

(1) In the airflow environment system 1, the airflow direction (reflux direction A3) through which the recirculating air flow flows is set to the first recirculation direction A31 and the second recirculation direction by the wind direction changing portion 9 provided at the outer peripheral end of the reflection portion 8. It is configured to be switchable to A32. As a result, when the airflow is returned to the environmental space 10, the airflow direction can be automatically switched between the first return direction A31 and the second return direction A32 by the wind direction changing unit 9 at the outer peripheral end of the reflection unit 8. can. Therefore, it is possible to reduce the draft feeling (discomfort) due to the airflow blown toward the user without the user having to replace the reflective portion with one having a different shape as in the conventional airflow environment system.

(2) In the airflow environment system 1, the curved surface 8a of the reflecting portion 8 is located in the first region 81 where the air flow flowing along the specific direction A1 hits, and around the first region 81, and hits in the first region 81. It has a second region 82 that flows along the air flow and reaches the wind direction changing portion 9. As a result, an air flow flowing from the first region 81 to the wind direction changing portion 9 along the reflecting portion 8 is formed, so that a layer of air flow returning from the wind direction changing portion 9 to the discharge port 5 side is formed. This facilitates the possibility that the environmental space 10 is divided into two spaces by the layer. Therefore, the user's sensation of airflow is improved.

(3) In the air flow environment system 1, the first flow path P1 in which the air flow discharged from the discharge port 5 flows toward the reflection unit 8 and the second air flow recirculated by the wind direction changing unit 9 flow in the environment space 10. The flow path P2 is formed, and when viewed along a specific direction A1, the second flow path P2 is formed so as to surround the first flow path P1. As a result, the user who approaches the side of the first flow path P1 is more likely to come into contact with the layer of the air flow that returns through the second flow path P2. Therefore, the user's sensation of airflow is improved. In particular, the velocity of the air flow returning through the second flow path P2 may be attenuated by the reflection section 8 and the wind direction changing section 9 and may be 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 passes through the second flow path P2 toward the reflecting portion 8 and returns to the side of the discharge port 5 through the first flow path P1, the first flow. It is possible to reduce the possibility of causing discomfort to the user approaching the side of one flow path P1.

(4) In the airflow environment system 1, the first recirculation direction A31 is the direction in which the recirculating air flow is directed toward the feet of the user sitting on the pedestal, and the second recirculation direction A32 is the direction in which the recirculating air flow is the pedestal. The direction was set so that the air flowed toward the head of the user sitting on the floor. As a result, when the user seated on the pedestal feels uncomfortable with the air flow recirculated in the second recirculation direction A32, the user simply switches to the air flow recirculated in the first recirculation direction A31 by the wind direction changing unit 9. The amount of airflow that directly hits the airflow can be reduced. Therefore, it is possible to surely reduce the draft feeling due to the air flow felt by the user.

(5) In the airflow environment system 1, the discharge port 5 and the reflection portion 8 are separated from each other through the hollow portion 13 of the gap in a specific direction A1, and the air flow and the wind direction change portion discharged from the discharge port 5 are separated from each other. The air flow recirculated by 9 is made to flow through the hollow portion 13. As a result, there is no obstacle that separates the air flow flowing along the specific direction A1 and the air flow returning to the side of the discharge port 5 from each other. Therefore, it is possible to increase the possibility of giving a feeling of openness to the user in the environmental space 10.

It is controlled separately from the two wind direction changing units 92. The division of the plurality of wind direction changing units 9 may be assigned by the user directly by selecting and assigning the first wind direction changing unit 91 and the second wind direction changing unit 92 by the operation panel 4a, or the processing unit. The program processed by 12b may automatically assign the first wind direction changing unit 91 and the second wind direction changing unit 92. Here, of the plurality of wind direction changing portions 9 attached to the reflecting portion 8, half of the adjacent wind direction changing portions 9 are designated as the first wind direction changing portion 91, and the rest are referred to as the second wind direction changing portion 92. In FIG. 10, the right half of the wind direction changing section 9 is shown as the first wind direction changing section 91, and the remaining left half is shown as the second wind direction changing section 92.

Specifically, the control unit 12 in the airflow environment system 1A receives information regarding the classification of the wind direction changing unit 9, and based on the information, the wind direction changing unit 9 is combined with the first wind direction changing unit 91 and the second wind direction changing unit 92. It is divided into. Then, the control unit 12 specifies that the first wind direction changing unit 91 is in the first state based on the information regarding the set angle of the wind direction changing unit 9, and controls the reflux direction A3 to be the first reflux direction A31. do. Further, the control unit 12 specifies that the second wind direction changing unit 92 is in the second state based on the information regarding the set angle of the wind direction changing unit 9, and controls the reflux direction A3 to be the second reflux direction A32. do. As a result, in the airflow environment system 1A, in the environmental space 10, the air flowing through the first wind direction changing section 91 and flowing through the first intermediate layer X1 and the air flowing back through the second wind direction changing section 92 are returned. The second intermediate layer X2 into which the flow flows is formed independently of each other.

Here, as in the state of the wind direction changing unit 9 shown in the first embodiment, in the first state, the first reflux direction A31 by the first wind direction changing unit 91 is at the feet of the user seated on the pedestal of the housing 4. In the second state, the second return direction A32 by the second wind direction changing unit 92 is the direction in which the air flow flows toward the head of the user who is seated on the pedestal of the housing 4. The direction. Therefore, the user seated on the pedestal in the second intermediate layer X2 can feel the airflow more strongly than the user seated on the pedestal in the first intermediate layer X1. Therefore, for the user seated on the pedestal in the first intermediate layer X1 and the user seated on the pedestal in the second intermediate layer X2, the discomfort due to the draft feeling is eliminated and the draft feeling is maintained at the same time. Can be provided.

As described above, according to the airflow environment system 1A according to the second embodiment, the following effects can be enjoyed.

(6) In the airflow environment system 1A, a plurality of wind direction changing units 9 are configured by dividing the first wind direction changing unit 91 and the first wind direction changing unit 91 and the second wind direction changing unit 92 having different reflux directions A3. .. As a result, in the environmental space 10, a space through which the air flow returning through the first wind direction changing portion 91 flows (first intermediate layer X1) and a space in which the air flow returning through the second wind direction changing portion 92 flows (second). The intermediate layer X2) can be formed independently of each other. Therefore, it is possible to blow an air flow suitable for the user for each space divided by the wind direction changing unit 9, and it is possible to reduce the possibility of causing discomfort to the user.

In the airflow environment system 1 according to the first embodiment, the control unit 12 controls the airflow direction so as not to cause discomfort due to the draft feeling to the user, but the present invention is not limited to this. For example, the control unit 12 may control to change the direction of the downward flow that blows toward the user depending on the season (summer or winter).

In the airflow environment system according to the present embodiment, the specific direction A1 is preferably vertically upward. As a result, the airflow environment system can more stably form an air flow that returns to the side of the discharge port 5.

In the airflow environment system 1 according to the first embodiment, the processing unit 12b of the control unit 12 is controlled to fix the wind direction changing unit 9 in the first state or the second state, but the control is not limited to this. For example, the processing unit 12b may continuously drive the servomotor 9a to periodically change the state of the wind direction changing unit 9. In this case, the processing unit 12b has time information output from the time counting unit 12e, current angle information of the servomotor 9a output from the storage unit 12d, and information (angle and) regarding the periodic change of the angle of the servomotor 9a. The time interval) and the angle output information for the servomotor 9a (information on the on / off of the operation of the servomotor 9a and the number of rotations) may be specified and output to the output unit 12c. By doing so, it is possible to reduce the possibility of causing discomfort to the user because the air flow that the user feels unpleasant does not continuously hit.
