Description

[Technical field]

[0001] The present disclosure relates generally to airflow environmental systems, and more particularly to airflow environmental systems that create airflow in an environmental space. [Background technology]

[0002] As a conventional example, an air purifying device 100 described in Patent Document 1 is illustrated with reference to FIG. 6. FIG. 6 is an external perspective view showing the structure of the conventional air purifying device 100. As shown in FIG. 6, the conventional air purifying device 100 is installed in front of a smoking seat 101, which is an open space, and is configured to include a fixture 102 arranged in front of the smoking seat 101 and an intake unit 103 installed on the smoking seat 101 side. In the air purifying device 100, an air flow 105 discharged from an exhaust port 104 of the fixture 102 incorporating an air discharge unit is caused to flow obliquely upward toward an intake opening 106 in the intake unit 103, and is sucked into the intake opening 106. According to the air purifying device 100, cigarette smoke and the like are caught by the air flow 105 directed obliquely upward, so that an outer space that is a non-smoker's area and an inner space that is a smoker's area are separated from each other, and the diffusion of cigarette smoke and the like into the outer area can be suppressed.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 9-010528 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, according to the conventional air purifying device, although it is possible to suppress the air flow between the outer space and the inner space (environmental space) by using the air flow going in an obliquely upward direction, it is not sufficient to confine the air flow within the inner space and improve the comfort for users (airflow sensation, coolness, cleanliness, etc.) because there is room for air to flow in and out on the sides of the smoking seat. In other words, it is desired to improve the comfort of users in the environmental space.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide an airflow environment system that can improve the comfort of users in an environmental space. [Means for solving the problem]

[0006] To achieve this objective, the airflow environment system of the present invention generates an airflow in a specific space whose front side is an open surface that is open to an external space. The airflow environment system includes an outlet that releases an airflow flowing along a specific direction on the rear side of the specific space into the specific space, and a reflecting unit that is arranged to face the outlet in the specific direction and that is hit by the airflow flowing along the specific direction. The reflecting unit is configured to return the hit airflow to the floor side of the specific space so as to cross the open surface on the front side of the specific space, thereby achieving the above-mentioned objective.

[0009] The airflow environment system according to the present invention generates an airflow in a specific space whose front side is an open surface that is open to an external space. The airflow environment system includes an outlet that releases an airflow flowing along a specific direction on the rear side of the specific space into the specific space, and a reflecting unit that is arranged to face the outlet in the specific direction and that is hit by the airflow flowing along the specific direction. The reflecting unit is configured to return the hit airflow to the floor side of the specific space so as to cross the open surface on the front side of the specific space.

[0010] According to this configuration, the air flow reflected by the reflecting portion flows back to the floor side of the specific space so as to cross the open surface on the front side of the specific space, so that the air flow can be confined within the specific space. Then, an air flow from the front side to the rear side in the specific space is generated by an air flow (induced air flow) that is attracted by the air flow flowing along a specific direction on the rear side of the specific space, so that the user who uses the specific space can feel the air flow. In other words, compared to the case where a conventional air purifying device is used, the comfort of the user in the specific space can be improved. In other words, an airflow environment system that can improve the comfort of the user in the specific space can be provided.

[0011] In the airflow environment system according to the present invention, a seat on which a user can sit is installed in the specific space. The front side of the seat in the specific space is an open surface that is open to the outside space, and the outlet may be configured to release an airflow flowing in a specific direction on the back side of the seat into the specific space. In this way, the airflow reflected by the reflecting part flows back to the floor side of the seat so as to cross the open surface on the front side of the seat, so that the airflow can be confined within the specific space. An airflow (induced airflow) is generated in the specific space from the front side to the back side due to the airflow induced by the airflow flowing in a specific direction on the back side of the seat, so that the user using the seat can feel the airflow. In other words, the comfort of the user using the seat in the specific space can be improved compared to the case of using a conventional air purifying device.

[0012] In the airflow environment system according to the present invention, the outlet is preferably provided at a position lower on the floor surface side than the position of the user's head so that an airflow flowing in a specific direction flows between the user sitting in the seat and the wall surface that constitutes the specific space exposed behind the user. In this way, an induced airflow is generated behind the user including the head, so that the user can more reliably feel the airflow from the front side to the back side in the specific space. In other words, the comfort of the user in the specific space can be effectively improved.

[0013] In addition, the airflow environment system according to the present invention further includes an air intake port provided on the floor surface side of the seat portion for drawing in air from a specific space, and the air outlet directs the air drawn in from the air intake port in a specific direction. The reflecting portion may be configured to release the reflected air as an air flow that flows along the line. With this configuration, the air flow reflected by the reflecting portion is sucked in by the air intake port, so that the air flow can be more reliably trapped within the specific space. This makes it possible to more stably generate the flow of air (induced air flow) formed in the specific space.

[0014] Moreover, the airflow environment system according to the present invention further includes a functional unit that imparts an additional element to the airflow discharged from the outlet into the specific space, and the additional element preferably includes at least one of fragrance, air purification, humidity change, and temperature change. In this way, the additional element can be imparted to the airflow to fill the specific space with the additional element. The additional element is prevented from diffusing outside the specific space by the airflow reflected by the reflecting unit, so that the specific space can be easily maintained in a state where it is filled with the additional element. In other words, the comfort of the user in the specific space can be further improved.

[0015] The airflow environment system according to the present invention further includes a central air-conditioning room that introduces air from outside the specific space to add an additional element, and a duct that connects the central air-conditioning room to the outlet. The additional element may include at least one of fragrance, air purification, humidity change, and temperature change, and the outlet may be configured to release the air introduced from the central air-conditioning room as an air flow that flows along a specific direction. With this configuration, air (air with the additional element added) is supplied from the central air-conditioning room to the airflow environment system, so it can be easily applied to an airflow environment system having multiple independent specific spaces.

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the following embodiment is an example of the present invention, and does not limit the technical scope of the present invention. Also, each figure described in the embodiment is a schematic diagram, and the size and thickness ratios of each component in each figure do not necessarily reflect the actual dimensional ratios.

[0017] (Embodiment 1) First, an overview of an airflow environment system 1 according to embodiment 1 will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is an external perspective view of the airflow environment system 1 according to embodiment 1 of the present invention. Fig. 2 is a block diagram showing the configuration of an air blowing system 2 in the airflow environment system 1.

[0018] In the following explanation, the airflow environment system 1 will be viewed from the front, and the left-right direction (left side, right side), up-down direction (floor surface below, ceiling surface above), and front-back direction (front side near, back side far) will be defined.

[0019] The airflow environment system 1 is installed as a private room unit 10 that also serves as a rest room, a waiting room, etc., and is configured to form an airflow (air flow) that is comfortable for a user U (see FIG. 3) in a specific space SP1 formed in the private room unit 10. The specific space SP1 can also be called an environmental space.

[0020] As shown in FIG. 1, the airflow environment system 1 is configured to include a box-shaped private room unit 10, a seat section 3 equipped with an air blowing system 2, and a reflecting section 4.

[0021] The private room unit 10 is surrounded by a left wall 10a, a right wall 10b, a floor-side wall 10c, a ceiling-side wall 10d, and a rear-side wall 10e, and the front side of the seating section 3 has an open surface X that is open to the external space SP2. Note that the "open surface X" is a virtual surface with no substance, and is a virtual surface surrounded by the front end portions of the left wall 10a, the right wall 10b, the floor-side wall 10c, and the ceiling-side wall 10d. Inside the private room unit 10, the seating section 3 equipped with an air blowing system 2 is located on the floor side. A reflector 4 is installed on the ceiling side.

[0022] The air supply system 2 (seat section 3 equipped with the air supply system 2) is installed on a wall surface 10c on the floor side of the specific space SP1, and emits an air flow A1 (see FIG. 3) flowing along a first direction (the direction indicated by the arrow indicating the air flow A1 in FIG. 3), which is a specific direction, into the specific space SP1. The reflecting section 4 is installed on a wall surface 10d on the ceiling side of the specific space SP1 at a position facing the air supply system 2 in the first direction, and is hit by the air flow A1 flowing along the first direction. The reflecting section 4 is configured to return the hit air flow A2 to the floor side (the direction indicated by the arrow indicating the air flow A3 in FIG. 3) in the specific space SP1.

[0023] Specifically, the seat section 3 equipped with the ventilation system 2 will be described.

[0024] The seat 3 has a base and a backrest on which a user can sit. The seat 3 can also be said to serve as a member that constitutes the outer frame of the ventilation system 2, and is configured with the ventilation system 2, an outlet 5, and an intake 6.

[0025] The outlet 5 is disposed, for example, on the upper surface of the backrest of the seat 3. The outlet 5 is configured as a slit-shaped opening (or a plurality of holes) in a range from the left wall surface 10a to the right wall surface 10b. The outlet 5 is configured to communicate with the ventilation system 2, and releases the air blown from the ventilation system 2 into the specific space SP1 as an air flow A1 flowing along the first direction. In particular, the outlet 5 is provided at a position (floor surface side) lower than the position of the head of the user U so that the air flow A1 flowing along the first direction flows between the user U and the wall surface 10e exposed behind the user U (see FIG. 3). Here, the position of the head of the user U refers to the position of the head when the user U, who has at least a standard seated height, is seated in the seat 3 in a correct posture.

[0026] The air intake 6 is disposed on the front side of the floor surface side of the base of the seat 3, and is composed of, for example, a plurality of slit-shaped holes that are long in the vertical direction. The air intake 6 is configured to communicate with the ventilation system 2 via the internal space (not shown) of the seat 3, and as the ventilation system 2 blows air, it draws air from the specific space SP1 into the internal space.

[0027] As described above, the air supply system 2 is configured to be housed or held inside the seat portion 3. The air supply system 2 is connected in communication with the air outlet 5 and the air intake 6 in the internal space of the seat portion 3. Air in the specific space SP1 is supplied to the air supply system 2 from the air intake 6 and is discharged from the air outlet 5 to the specific space SP1.

[0028] Specifically, as shown in FIG. 2, the air blowing system 2 includes an air blowing device 2a and a functional unit 2b.

[0029] The blower 2a is a device that draws in air in the specific space SP1 through the intake port 6 under the control of a control unit (not shown), generates an airflow A1 flowing along a first direction (vertical upward direction), and sends it out to the discharge port 5. The blower 2a is, for example, a sirocco fan that generates an airflow that contains more linear components than swirling components. The blower 2a draws in air in the specific space SP1 through the intake port 6, and generates an airflow A1 flowing along the first direction. Here, the material of the blower 2a is not particularly limited, but it is preferable that the material is one whose durability is not affected by additional elements that are added to the airflow discharged from the discharge port 5 to the specific space SP1 by the functional unit 2b described later.

[0030] The functional unit 2b is a device that adds an additional element to the airflow discharged from the discharge port 5 to the specific space SP1. The additional element is at least one of a fragrance, air purification, a humidity change, and a temperature change. Also includes one.

[0031] When the additional element includes a fragrance, the functional unit 2b is housed in the seat unit 3. The additional element includes, for example, a fragrance presentation device including an aromatic agent. The fragrance vaporized from the aromatic agent mixes with the airflow flowing from the blower device 2a to the outlet 5. As a result, air with a good fragrance can be provided to the user U in the specific space SP1.

[0032] When the additional element includes air purification, the functional unit 2b has, for example, an air purification device. The air purification device is housed in the seat unit 3. The air purification device has a dust collection filter that collects fine particles such as pollen in the air sucked in from the air intake 6, a deodorizing filter, and the like. The air purified by the air purification device is discharged upward from the discharge port 5 as an air flow by the blower 2a. As a result, purified air can be provided to the user U in the specific space SP1.

[0033] When the additional element includes air purification, the functional unit 2b may have, for example, a space sterilizing deodorizer. The space sterilizing deodorizer is housed in the seat unit 3. The space sterilizing deodorizer is configured to generate hypochlorous acid and mix it into the airflow generated by the blower 2a. The airflow containing hypochlorous acid is discharged upward from the discharge port 5 to sterilize the specific space SP1. As a result, purified air can be provided to the user U in the specific space SP1.

[0034] When the additional element includes a humidity change, the functional unit 2b has, for example, a dehumidifier / humidifier. The dehumidifier / humidifier is housed in the seat unit 3. Air that has been humidified (dehumidified or humidified) by the dehumidifier / humidifier is discharged upward from the discharge port 5 as an air flow by the blower 2a. As a result, air with a comfortable humidity level can be provided to the user U in the specific space SP1.

[0035] When the additional element includes a temperature change, the functional unit 2b 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 outlet 5 as an air flow by the blower 2a. As a result, air at a comfortable temperature can be provided to the user U in the specific space SP1.

[0036] When the functional unit 2b has the above-mentioned air purifier, spatial sterilization and deodorization device, dehumidification device, and air conditioner, the power on / off and adjustment of various parameters can be performed, for example, by operating an operation panel (not shown). Note that the operation of the functional unit 2b may be controlled to be linked to the operation of the blower 2a under the control of the control unit.

[0037] By providing the functional part 2b to the air blowing system 2 in this way, an additional element can be easily added to the air flow.

[0038] Next, the reflecting section 4 will be described with reference to Fig. 3. Fig. 3 is a schematic diagram for explaining the airflow generated by the airflow environment system 1.

[0039] As shown in Fig. 3, the reflecting section 4 is installed on the wall surface 10d on the ceiling surface side of the private room unit 10. The reflecting section 4 is disposed so as to face the discharge port 5 in the first direction (vertical upward direction), and the lower surface of the reflecting section 4 (the surface facing the discharge port 5) has a curved surface 4a with a recessed central portion and an approximately semi-cylindrical (semi-cylindrical) shape. Specifically, the approximately semi-cylindrical curved surface 4a has an axial direction approximately parallel to the open surface X and the wall surface 10c on the floor surface side, and is curved in an arc shape so as to be convex toward the ceiling surface side when viewed along the axial direction.

[0040] In the reflecting section 4, when the airflow environment system 1 (air blowing system 2) is in operation, the airflow A1 (airflow A1 flowing along the first direction) discharged from the discharge port 5 hits the curved surface 4a of the reflecting section 4. The airflow that hits the curved surface 4a is then reflected along the curved surface 4a in a second direction. The air flow A1 flows in the first direction (from the back side to the front side) while being reflected. Furthermore, the air flow A2 flowing in the second direction is emitted from the end of the front side of the curved surface 4a toward the floor side (the direction indicated by the arrow indicating the air flow A3 in FIG. 3). In other words, the reflecting portion 4 is configured so that the air flow A1 flowing along the first direction hits the reflecting portion 4, and the hit air flow A2 (air flow A2 flowing in the second direction) is returned to the floor side of the seat portion 3 so as to cross the open surface X on the front side of the seat portion 3 in the up-down direction.

[0041] Next, the airflow of the airflow environment system 1 will be described with reference to FIG.

[0042] In the airflow environment system 1, as described above, the airflow A1 flowing along the first direction is discharged from the discharge port 5 by the air blowing system 2. Here, the airflow A1 discharged from the discharge port 5 flows along the wall surface 10e due to the attraction phenomenon caused by the Coanda effect (a negative pressure area is generated between the discharged air and the wall surface 10e, and the discharged airflow is attracted to the negative pressure area). Then, the airflow A1 discharged from the discharge port 5 hits the curved surface 4a at the end of the back side of the curved surface 4a in the reflecting section 4. Then, the airflow A2 that hits the curved surface 4a flows so as to be reflected in the second direction along the curved surface 4a. Then, the airflow A2 flowing in the second direction is discharged from the end of the front side of the curved surface 4a toward the floor side as the airflow A3 flowing in the third direction (direction from the ceiling surface side toward the floor surface side). The released airflow A3 then flows vertically (from the ceiling side to the floor side) across the open surface X of the private room unit 10 toward the floor side. The airflow A4 that has flowed toward the floor side flows in a fourth direction (from the front side to the back side) along the wall surface 10c and is sucked in through the air intake 6 of the seat section 3. The sucked in airflow is then released again by the ventilation system 2 as the airflow A1 that flows in the first direction. In this way, a series of airflows (airflows A1 to A4) are formed in the specific space SP1.

[0043] In the airflow environment system 1, the airflow A3 vertically crossing the open surface X functions as an air curtain, thereby suppressing the airflow between the specific space SP1 and the external space SP2. At this time, the left wall surface 10a and the right wall surface 10b suppress the inflow of air into the private room unit 10 or the outflow of air to the outside of the private room unit 10, thereby confining the airflow within the specific space SP1.

[0044] In addition, in the airflow environment system 1, an induced airflow B1 is generated by the airflow A1 flowing along the first direction on the back side of the seat 3. Furthermore, the flow of this induced airflow B1 generates an airflow (induced airflow B2) from the front side to the back side in the specific space SP1. As a result, a series of air flows (airflows A1 to A4) generates an induced airflow (induced airflow B1, induced airflow B2) from the front side to the back side in the specific space SP1. In other words, a user U using the seat 3 can feel the flow of these airflows.

[0045] As described above, the airflow environment system 1 can trap air within a specific space SP1 in which the front side of the private unit 10 is an open surface X that is open to the external space SP1, and can generate an airflow within the specific space SP1.

[0046] As described above, according to the airflow environment system 1 according to the first embodiment, the following effects can be obtained.

[0047] (1) The airflow environment system 1 includes an outlet 5 that discharges an airflow A1 flowing along a first direction on the back side of the seat 3 into a specific space SP1, and a reflecting unit 4 that is disposed opposite the outlet 5 in the first direction and that is hit by the airflow A1 flowing along the first direction. The airflow A2 that has hit the reflecting unit 4 is reflected by the airflow A2 as it traverses the open surface X on the front side of the seat 3. In this way, the airflow A3 reflected by the reflecting unit 4 is returned to the floor side of the seat unit 3 so as to cross the open surface X on the front side of the seat unit 3, so that the airflow can be confined within the specific space SP1. Then, an airflow (induced airflow B1) induced by the airflow A1 flowing along the first direction on the back side of the seat unit 3 generates an airflow (induced airflow B2) from the front side to the back side in the specific space SP1, so that the user U using the seat unit 3 can feel the airflow. In other words, the comfort of the user U in the specific space SP1 can be improved compared to the case where a conventional air purifying device is used. In other words, the airflow environment system 1 can be made to be capable of improving the comfort of the user U in the specific space SP1.

[0048] (2) In the airflow environment system 1, the outlet 5 is provided at a position lower on the floor surface side than the position of the head of the user U so that the airflow A1 flowing in the first direction flows between the user U seated in the seat 3 and the wall surface (wall surface 10e) constituting the specific space exposed behind the user U. This generates an induced airflow B1 behind the user U including his / her head, so that the user U can more reliably feel the airflow (induced airflow B2) from the front side toward the back side in the specific space SP1. In other words, the comfort of the user U in the specific space SP1 can be effectively improved.

[0049] (3) In the airflow environment system 1, an air intake 6 is provided on the floor side of the seating section 3 to draw in air from the specific space SP1, and the air outlet 5 is configured to discharge the air (air including airflow A4) drawn in from the air intake 6 as airflow A1 flowing along the first direction. This allows the airflow A3 reflected by the reflecting section 4 (the subsequent airflow A4) to be drawn in by the air intake 6, so that the airflow can be more reliably contained within the specific space SP1. This makes it possible to more stably generate the flow of air (induced airflow B1 and induced airflow B2) formed in the specific space SP1.

[0050] (4) In the airflow environment system 1, a functional unit 2b is provided that imparts an additional element to the airflow A1 discharged from the outlet 5 into the specific space SP1, and the additional element includes at least one of fragrance, air purification, humidity change, and temperature change. This allows the additional element to be imparted to the airflow A1, filling the specific space SP1 with the additional element. The airflow A3 reflected by the reflecting unit 4 prevents the additional element from diffusing outside the specific space SP1 (outside space SP2), making it easier to maintain the situation in which the specific space SP1 is filled with the additional element. In other words, the comfort of the user U in the specific space SP1 can be further improved.

[0051] (Embodiment 2) An airflow environment system 1a according to the second embodiment of the present invention differs from the first embodiment in that it is configured to receive an airflow supply from a centralized airflow system 12 instead of an airflow supply from a ventilation system 2. Other than this, the configuration of the airflow environment system 1a is the same as that of the airflow environment system 1 according to the first embodiment. Below, the contents already explained in the first embodiment will not be explained again as appropriate, and the differences from the first embodiment will be mainly explained.

[0052] An airflow environment system 1a according to a second embodiment of the present invention will be described with reference to Fig. 4. Fig. 4 is a schematic diagram of the airflow environment system 1a according to the second embodiment of the present invention.

[0053] As shown in Fig. 4, the airflow environment system 1a is configured to be connected in communication with a centralized air blowing system 12 via a duct 11. The centralized air blowing system 12 corresponds to the "centralized air-conditioned room" in the claims.

[0054] The duct 11 is connected in communication with the exhaust port 5 from the internal space of the seat portion 3. Therefore, the seat portion 3 is not provided with an intake port 6.

[0055] The centralized air supply system 12 is configured with an air supply device 12a and a functional unit 12b, each of which has the same functions as the air supply system 2 (air supply device 2a and functional unit 2b). The centralized air supply system 12 is installed in an air-conditioning room or the like separated from the airflow environment system 1a, and supplies air to the airflow environment system 1a. For this reason, the centralized air supply system 12 takes in air outside the specific space SP1 (air in the external space SP2) and supplies it to the airflow environment system 1a. Meanwhile, the centralized air supply system 12 is also connected in communication with an airflow environment system 1b that is different from the airflow environment system 1a. This makes it possible to supply air to a plurality of airflow environment systems.

[0056] In the airflow environment system 1a, similarly to the airflow environment system 1, the front side of the private room unit 10 is an open surface X that is open to the outside space SP1, and in the specific space SP1, air can be trapped within the specific space SP1 and an airflow can be generated within the specific space SP1. In the airflow environment system 1a, the airflow A3 flowing in the third direction is adapted to diffuse along the floor surface side.

[0057] As described above, according to the airflow environment system 1a of the second embodiment, the following effects can be obtained.

[0058] (5) The airflow environment system 1a is provided with a centralized air supply system 12 that introduces air from outside the specific space SP1 (external space SP2) to add an additional element, and a duct 11 that connects the centralized air supply system 12 to the outlet 5. The additional element includes at least one of fragrance, air purification, humidity change, and temperature change. The outlet 5 is configured to release the air introduced from the centralized air supply system 12 as an air flow A1 that flows along the first direction. This allows air (air with the additional element added) to be supplied from the centralized air supply system 12 to the airflow environment system 1a, and therefore the system can be easily applied to an airflow environment system 1b having a plurality of independent specific spaces SP1.

[0059] (Embodiment 3) An airflow environment system 1c according to embodiment 3 of the present invention differs from embodiment 1 in that, instead of a seat section 3 equipped with an airflow system 2, the airflow environment system 1c is configured with an airflow unit 3a equipped with an airflow system 2. Other than this, the configuration of the airflow environment system 1c is similar to that of the airflow environment system 1 according to embodiment 1. Below, the contents already explained in embodiment 1 will not be explained again as appropriate, and differences from embodiment 1 will be mainly explained.

[0060] An airflow environment system 1c according to a third embodiment of the present invention will be described with reference to Fig. 5. Fig. 5 is a schematic configuration diagram of the airflow environment system 1c according to the third embodiment of the present invention.

[0061] In the airflow environment system 1c, as shown in FIG. 5, a box-shaped private room unit 10 having an open surface X does not have a seating area where a user U can sit, and the user U uses the private room unit 10 while standing.

[0062] As shown in FIG. 5, the blower unit 3a is installed on the wall surface 10c on the floor side, adjacent to the wall surface 10e on the rear side of the specific space SP1. The blower unit 3a emits air flow A1, which flows along a first direction (the direction indicated by the arrow showing the air flow A1), which is a specific direction, into the specific space SP1. The reflecting section 4 is installed on the wall surface 10d on the ceiling side of the specific space SP1, at a position facing the blower unit 3a in the first direction, and is hit by the air flow A1 flowing along the first direction. The reflecting section 4 is installed in the specific space SP1, at a position facing the blower unit 3a in the first direction, and is hit by the air flow A1 flowing along the first direction. The reflecting section 4 is disposed in the specific space SP1, and is configured to reflect the air flow A1. The airflow A2 is returned to the floor surface side (in the direction indicated by the arrow showing the airflow A3).

[0063] Specifically, the air blowing unit 3a equipped with the air blowing system 2 will be described.

[0064] It can be said that the air blowing unit 3a also serves as a member that constitutes the outer frame of the air blowing system 2, and is configured to include the air blowing system 2, an outlet 5a, and an intake 6a.

[0065] The outlet 5a is disposed on the upper surface of the blower unit 3a. Although not shown in particular, the outlet 5a is configured as a slit-shaped opening (or a plurality of holes) extending from the left wall surface 10a to the right wall surface 10b, similar to the outlet 5. The outlet 5a is configured to communicate with the blower system 2, and releases the air blown from the blower system 2 into the specific space SP1 as an air flow A1 flowing along the first direction. The position where the outlet 5a is formed (height from the floor surface side) is approximately the same height as the position where the outlet 5 in the seat portion 3 is formed.

[0066] The air intake 6a is disposed on the front side of the floor surface side of the air blowing unit 3a and is composed of, for example, a plurality of slit-shaped holes that are long in the vertical direction. The air intake 6a is configured to communicate with the air blowing system 2 via the internal space (not shown) of the air blowing unit 3a, and draws air from the specific space SP1 into the internal space as the air blowing system 2 blows air.

[0067] As described above, the air blowing system 2 is configured to be housed or held inside the air blowing unit 3a. The air blowing system 2 is connected to the air outlet 5a and the air inlet 6a in the internal space of the air blowing unit 3a. The air in the specific space SP1 is supplied to the air blowing system 2 from the air inlet 6a and discharged from the air outlet 5a to the specific space SP1.

[0068] The airflow generated by the airflow environment system 1c is similar to the airflow generated by the airflow environment system 1, and therefore a description thereof will be omitted.

[0069] As described above, the airflow environment system 1c can confine air within a specific space SP1 in which the front side of the private unit 10 is an open surface X that is open to the external space SP1, and can generate an airflow within the specific space SP1.

[0070] As described above, according to the airflow environment system 1c according to the third embodiment, the following effects can be obtained.

[0071] (6) The airflow environment system 1c includes an outlet 5a that releases an airflow A1 flowing along a first direction on the rear side of the specific space SP1 into the specific space SP1, and a reflecting unit 4 that is arranged to face the outlet 5a in the first direction and is hit by the airflow A1 flowing along the first direction. The reflecting unit 4 is configured to return the hit airflow A2 to the floor side of the specific space SP1 so as to cross the open surface X on the front side of the specific space SP1. In this way, the airflow A3 reflected by the reflecting unit 4 returns to the floor side so as to cross the open surface X on the front side of the specific space SP1, so that the airflow can be trapped within the specific space SP1. An airflow (induced airflow B1) induced by the airflow A1 flowing along the first direction on the rear side of the specific space SP1 generates an airflow (induced airflow B2) from the front side to the rear side in the specific space SP1, so that a user U who uses the specific space SP1 in a standing position can feel the airflow. That is, compared to the case where a conventional air purifying device is used, the comfort of the user U in the specific space SP1 can be improved.

[0072] The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and it can be easily imagined that various improvements and modifications are possible within the scope of the present invention without departing from the spirit of the present invention.

[0073] In the airflow environment system 1 according to the first embodiment, the air intake 6 is provided in the seat section 3 to circulate the airflow, but this is not limited to the above. For example, the air intake 6 may not be provided, and the airflow A3 flowing in the third direction may be diffused along the floor surface side. With such a configuration, the above-mentioned effects can be obtained.

[0074] In addition, in the airflow environment system 1 according to the first embodiment, the outlet 5 is provided on the upper surface of the backrest of the seat 3, but this is not limited to this. For example, a gap may be provided between the seat 3 and the wall surface 10e, and the outlet 5 may be located in the gap. This increases the design freedom of the airflow environment system 1. [Industrial Applicability]

[0075] As described above, the airflow environment system according to the present embodiment is useful because it can improve the comfort of users in an environmental space. [Explanation of symbols]
