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

The air blowing system 1 according to this embodiment includes a pair of nozzle parts 2, as shown in FIG. The pair of nozzle parts 2 each blow out airflow along the one surface 101 from both sides (left and right sides in FIG. 1) of the one surface 101 of the structure X1. In the present disclosure, "along one surface 101" includes not only "parallel to one surface 101" but also "heading diagonally in front of one surface 101." Further, in the following, it is assumed that the number of nozzle parts 2 is two, but it may be three or more, and the ventilation system 1 may be provided with two pairs of nozzle parts 2 (total of four), for example. .

Here, as shown in FIG. 2, the pair of nozzle parts 2 collide the airflows blown out from each in a direction approaching each other, so that the air flows away from the one surface 101 along the direction intersecting the one surface 101. It is configured to generate a combined airflow G1.

According to this configuration, the combined airflow G1 caused by the collision of the airflows blown out from the pair of nozzle parts 2 flows away from the one surface 101. Therefore, for example, if a person is present in front of one surface 101, that person can experience the combined airflow G1. As a result, it is possible to provide an airflow with a more realistic feeling than when, for example, the airflow blown out from a single nozzle section is directly directed toward a person. As a result, the sensation of airflow can be improved.

In this embodiment, as an example, it is assumed that the structure X1 is the window member 102 (see FIGS. 1 and 2). The ventilation window 100 according to this embodiment includes the ventilation system 1 and a window frame 103 that supports the window member 102. The window frame 103 has a pair of frame pieces 104 facing each other. The pair of nozzle parts 2 are respectively arranged inside the pair of frame pieces 104 so that the air outlet 20 that blows out the airflow is exposed from the window frame 103.

As an example, the ventilation window 100 is assumed to be installed on a high floor in a facility such as an apartment (apartment housing complex), a hotel, or an office building, where it is relatively difficult to open and close the window (window member 102). do. The ventilation window 100 is assumed to be, for example, a window in which a window member 102 is fixed to a window frame 103 and cannot be opened or closed. However, the window member 102 may be supported so as to be openable and closable relative to the window frame 103. In addition to the above-mentioned facilities, the ventilation window 100 can be installed in detached houses, theaters, movie theaters, public halls, playgrounds, complexes, restaurants, department stores, schools, inns, hospitals, nursing homes, kindergartens, and libraries. , a museum, an art gallery, an underground mall, a station, or an airport.

According to this configuration, it is possible to provide the ventilation window 100 equipped with the ventilation system 1 that can improve the sensation of airflow. In addition, although the window member 102 (structure X1) is also demonstrated below as one of the components of the ventilation window 100, the window member 102 is not an essential component for the ventilation window 100. For example, at a site where the ventilation window 100 is installed, the window member 102 may be appropriately installed later in accordance with a user's request.

(2) Details Hereinafter, the overall configuration of the ventilation window 100 equipped with the ventilation system 1 according to the present embodiment will be described in detail with reference to FIGS. 1 to 3.

(2.1) Overall Configuration As described above, the blower window 100 is applied as a window used in the outer wall of, for example, a high floor in a facility. Inside the facility, a person (hereinafter referred to as a "user") standing next to the window of the ventilation window 100 can view the external scenery outside the facility through the ventilation window 100.

FIG. 1 is an external view of the ventilation window 100 as seen from inside a facility in a state where the ventilation window 100 is installed on a wall. In the following, the vertical and horizontal directions of the ventilation window 100 when viewed from the front indoors with the ventilation window 100 installed on a wall (see FIG. 1) are referred to as the vertical and horizontal directions of the ventilation window 100. do. Further, the indoor side with respect to the ventilation window 100 is the front side (front side) of the ventilation window 100, and the outside view side with respect to the ventilation window 100 is the rear side of the ventilation window 100. However, these directions are not intended to limit the direction in which the ventilation window 100 is used.

The ventilation window 100 has an overall rectangular shape that is elongated in the vertical direction. As described above, the ventilation window 100 includes the ventilation system 1, the window member 102 (structure X1), and the window frame 103 (see FIG. 1).

(2.2) Window member and window frame The window member 102 has a rectangular plate shape. The window member 102 is made of a translucent material. The window member 102 is, for example, transparent, but may be semitransparent. Further, the window member 102 is made of a glass plate, but is not particularly limited, and may be made of an acrylic plate, a polycarbonate plate, or the like depending on the usage of the ventilation window 100. Moreover, the window member 102 is not only configured by one plate material, but may also be configured by two or more plate materials arranged in the thickness direction (for example, double-glazed glass, etc.).

The window frame 103 is configured to support the structure X1, which is the window member 102. The window frame 103 is formed into a rectangular frame shape so as to surround the four sides of the window member 102 which is a rectangular plate shape. A detailed explanation of the structure in which the window frame 103 supports the window member 102 will be omitted here, but for example, grooves into which the four sides of the window member 102 are fitted are formed on the inner side surface of the window frame 103. There is.

As shown in FIG. 1, the window frame 103 includes a pair of frame pieces 104 facing each other in the left-right direction and a pair of frame pieces 105 facing each other in the vertical direction. Each frame piece 104 has a rectangular prismatic shape extending in the vertical direction. Each frame piece 105 has a rectangular prismatic shape extending along the left-right direction. The window frame 103 has a rectangular frame shape because a pair of frame pieces 104 and a pair of frame pieces 105 are integrally connected. Frame piece 104 is longer than frame piece 105.

Each frame piece 104 has an accommodation space therein for accommodating a part of the nozzle section 2 (described later) of the air blowing system 1. In particular, each frame piece 104 is provided with a slit-shaped through hole 106 for exposing the air outlet 20 of the nozzle section 2 to the outside. The through hole 106 connects the housing space to the outside. Each through hole 106 is elongated in the vertical direction. Each through hole 106 penetrates in the left-right direction on the inner surface 107 of the corresponding frame piece 104 (the opposing surface between the pair of frame pieces 104), and communicates with the accommodation space. In particular, each through hole 106 is arranged in a region in front of one surface 101 (front surface) of the window member 102 (structure X1) on the inner surface 107 thereof.

(2.3) Air Blowing System As described above, the air blowing system 1 includes a pair of nozzle sections 2 (see FIGS. 1 to 3). As shown in FIG. 3, the blower system 1 includes one or more (here, two) blowers 4, a control unit 6, a functional section 5, an operation section 7, and one or more (here, two) blowers 4. ) and a sensor Z1.

The two blowers 4 (fan sections) are disposed upstream of the pair of nozzle sections 2, and are configured to generate airflow and individually send it to the pair of nozzle sections 2 one-on-one. Specifically, each blower 4 generates an air flow flowing in a specific direction under the control of the control unit 6, for example, and blows the air between the pair of nozzle parts 2 through the flow path C2 (see FIG. 3). Send it to one side. The flow path C2 is constituted by a pair of ducts, each of which spatially connects the blower 4 and the nozzle section 2. That is, here, since there are two blowers 4, the pair of ducts is configured to connect the two blowers 4 and the pair of nozzle parts 2 one-to-one, respectively.

The number of blowers 4 may be one, and in this case, the duct may be configured to branch into two in the middle in order to send airflow to the pair of nozzle portions 2 individually. In this case, it is desirable to provide a damper for adjusting the air volume in the middle of the bifurcated branch path so that the air volume of the air flow blown out from each of the pair of nozzle parts 2 can be adjusted individually.

Each blower 4 is, for example, a sirocco fan that generates an air flow containing more straight components than swirling components. A functional section 5 is arranged around the blower 4, and the blower 4 sucks air containing the additional elements provided by the functional section 5 to generate an air flow. Note that the blower 4 is not limited to a sirocco fan, and may be a propeller fan. The ventilation system 1 of this embodiment is configured to circulate indoor air. Therefore, the air inlet toward the blower 4 is installed indoors.

Each blower 4 can change the air volume as appropriate by adjusting the rotational speed of the motor under, for example, inverter control. For example, the operation unit 7 is provided with a volume for adjusting the air volume, so that the user can adjust the air volume of the blower 4 as appropriate at the installation site of the ventilation window 100. Further, the control unit 6 can automatically change the air volume of the blower 4.

In this embodiment, the blower 4, together with the control unit 6, constitutes an "airflow control section 3" that applies a change (first change) regarding the airflow of the airflow to the airflow blown out from the pair of nozzle sections 2. . In other words, the ventilation system 1 includes the airflow control section 3. When there are two blowers 4, the first change may be applied to the airflow blown out from the corresponding nozzle part 2 through only one blower 4. In short, in the ventilation system 1, it is not essential to apply the first change to the airflow blown out from both of the pair of nozzle parts 2. Further, when a damper for adjusting air volume is placed in the middle of the duct, the damper can also be one of the components of the airflow control section 3.

Each of the pair of nozzle parts 2 is, for example, a molded product of synthetic resin, but is not particularly limited. Each of the pair of nozzle parts 2 may be a molded product of metal (for example, aluminum, etc.). The pair of nozzle parts 2 are configured so that each blows out an air flow along one surface 101 from both sides (in this case, both left and right sides) of one surface 101 of the window member 102 that is the structure X1.

The pair of nozzle parts 2 are lined up in the left-right direction (see line-up direction D1 in FIG. 2). The pair of nozzle parts 2 have substantially the same shape and the same size, and are arranged so as to be plane symmetrical in the left-right direction. Each nozzle portion 2 has a flat, hollow, rectangular tube shape with both first and second ends 21 and 22 open. Hereinafter, when a pair of left and right nozzle sections 2 are to be explained while being distinguished from each other, the left nozzle section 2 may be referred to as a nozzle section 2A, and the right nozzle section 2 may be referred to as a nozzle section 2B.

When viewed along the thickness direction, each nozzle portion 2 has a vertical dimension that gradually increases from the first end portion 21 to the second end portion 22, and has an approximately triangular shape as a whole. There is. Further, each nozzle part 2 extends along the front-rear direction from the first end part 21 to the vicinity of the second end part 22, and the second end part 22 is bent so as to face the other nozzle part 2. (See Figure 2).

An inlet 23 (see FIG. 1) through which an air flow from the upstream side (blower 4 side) can be introduced is provided on the end surface of the first end 21, and an inlet 23 (see FIG. 1) is provided on the end surface of the second end 22. A blowout port 20 (see FIG. 2) is provided for blowing out the air flow introduced therein. The air outlets 20 of the pair of nozzle parts 2 face each other in the arrangement direction D1. The internal flow path 24 through which air flows from the inlet 23 to the outlet 20 in each nozzle portion 2 is bent into a substantially L-shape when viewed in the vertical direction (see FIG. 2). In other words, each of the pair of nozzle parts 2 has an air outlet 20 that blows out an air flow along one surface 101 of the window member 102. The air outlet 20 has a slit shape whose longitudinal direction is along one surface 101. Here, the air outlet 20 is along the vertical direction.

Similar to the outer contour of the nozzle portion 2, the internal flow path 24 gradually increases in vertical dimension from the first end 21 toward the second end 22. The airflow passing through the internal flow path 24 can be blown out from the air outlet 20 at a substantially uniform air volume in the vertical direction.

The pair of nozzle parts 2 configured in this manner are respectively arranged inside the pair of frame pieces 104 so that the air outlet 20 for blowing out the airflow is exposed from the through hole 106 of the window frame 103. In this embodiment, of each nozzle part 2, only the second end part 22 and its surrounding parts are housed in the corresponding frame piece 104, and the other parts including the first end part 21 are housed in the frame piece 104. It is held on the window frame 103 while protruding from the rear side of the window frame 104.

The control unit 6 has a function of controlling the air volume of the blower 4. That is, as described above, the control unit 6, together with the blower 4, constitutes the "airflow control section 3" that provides the first change. When a damper for adjusting air volume is disposed in the middle of the duct, the control unit 6 may have a function of controlling the opening/closing operation of the damper.

The control unit 6 is housed in a housing 9 (see FIG. 3) together with the blower 4, for example. The control unit 6 includes, for example, a computer system with a processor and a memory. The computer system functions as the control unit 6 by the processor executing the program stored in the memory. Although the program executed by the processor is pre-recorded in the memory of the computer system here, it may also be provided recorded on a non-temporary recording medium such as a memory card, or provided via a telecommunications line such as the Internet. may be done.

The operation unit 7 accepts operation input from the outside (user). The operation unit 7 is provided, for example, on a wall in the facility. A user can turn on and off the power of the ventilation system 1 by operating the operation unit 7. When the control unit 6 receives an operation to turn on the power at the operation unit 7, it starts driving the blower 4. Further, the user can adjust the air volume of each blower 4 by operating the air volume adjustment volume of the operation unit 7. When the control unit 6 receives an operation to adjust the air volume through the operation unit 7, it changes the air volume of the blower 4 in accordance with the operation. The operation unit 7 may be a remote controller, and in that case, a light receiving unit that receives infrared rays emitted from the operation unit 7 may be provided at or near the window frame 103.

The two sensors Z1 are, for example, a human sensor 11 and an air volume (wind speed) sensor 12, as shown in FIG. Each sensor Z1 is connected to the control unit 6 in a wired (or wireless) manner. Each sensor Z1 outputs an electrical signal to the control unit 6. The control unit 6 controls the blower 4 to change the amount of airflow according to the electrical signals acquired from each sensor Z1.

The human sensor 11 is configured, for example, on the window frame 103 or on the window frame 103 so that its detection area R0 (see FIG. 2) is set in the space in front of one surface 101 of the window member 102 (structure X1). It will be installed nearby. The human sensor 11 detects, for example, light rays (heat rays) emitted from the human body of the user present in the detection area R0 in front of the window member 102, includes the detection result in an electrical signal, and outputs the result to the control unit 6. do. Specifically, for example, the detection area R0 is divided into three areas in front of the window member 102: a first area R1 on the left, a second area R2 in the center, and a third area R3 on the right. ing.

Based on the detection result of the human sensor 11, the control unit 6 determines whether the user has entered the detection area R0 or exited the detection area R0 (entry/exit determination), and whether the user has entered the first to third areas R1. - Determine in which area of R3 it exists (position determination).

When the control unit 6 determines that the user has entered the detection area R0 based on the entrance/exit determination, the control unit 6 may turn on the power to the blower 4 to automatically start blowing air. Further, when the control unit 6 determines that the user has left the detection area R0 by entering/exiting determination, the control unit 6 may turn off the power to the blower 4 and automatically stop blowing the air.

Further, when the control unit 6 determines that the user is present in the first area R1 through position determination, the control unit 6 automatically adjusts the air volume of the blower 4 so that the direction of the combined air flow G1 is directed toward the first area R1. It may be configured to adjust to. In other words, the control unit 6 (airflow control section 3) causes the airflows in the alignment direction D1 in which the pair of nozzle sections 2 are lined up to collide with each other so that the wind direction of the combined airflow G1 changes according to the result of the position determination. Adjust the position. Note that details regarding the change in wind direction of the combined air flow G1 will be described later.

The airflow sensor 12 is installed on the back side of the window member 102 so as to be in contact with the outside air so as to detect the airflow outside the facility. The air volume sensor 12 measures the wind speed using, for example, a thermal method (temperature change of the wind speed element), calculates the air volume, includes the calculation result (air volume information) in an electrical signal, and outputs it to the control unit 6.

Here, the control unit 6 is configured to automatically adjust the air volume of the blower 4 to approximately match the air volume outside the facility based on the air volume information acquired from the air volume sensor 12. That is, the ventilation system 1 performs control in accordance with the current air volume outside the facility at an installation site where it is difficult to open and close windows, such as on a high floor of the facility. As a result, a simulated environment that is linked to the actual natural environment can be recreated within the facility.

The functional section 5 is configured to provide an additional element to the airflow blown out from at least one (here, both) of the pair of nozzle sections 2. The additional element includes at least one of scent, air purification, and temperature change.

When the additional element includes a scent, the functional unit 5 has, for example, a scent presentation device that includes an aromatic agent. The scent presentation device is arranged, for example, on the upstream side of the pair of blowers 4 and near the blowers 4. The scent presentation device may be housed within the housing 9. Each blower 4 sucks in air containing a vaporized aroma from an aromatic agent, generates an air flow, and blows it out from a pair of nozzle sections 2. As a result, the user who is in front of the window member 102 can be provided with air with good quality fragrance.

When the additional element includes air purification, the functional unit 5 includes, for example, an air purification device. The air cleaning device is arranged, for example, upstream of the pair of blowers 4 and near the blowers 4. The air cleaning device may be housed within the housing 9. The air cleaning device includes a dust collection filter that collects fine particles such as pollen in the air, a deodorizing filter, and the like. Each blower 4 sucks air purified by the air purifier, generates an air flow, and blows it out from a pair of nozzle parts 2. As a result, purified air can be provided to the user in front of the window member 102.

Furthermore, when the additional element includes air purification, the functional unit 5 may include, for example, a space sterilization and deodorization machine. The space sterilization and deodorization machine is arranged, for example, in the vicinity of the blowers 4 on the upstream side of the pair of blowers 4. The space sterilization and deodorization machine may be housed within the housing 9. The space disinfection and deodorization machine is configured to produce hypochlorous acid. Each blower 4 sucks air containing hypochlorous acid, generates an air flow, and blows it out from a pair of nozzle parts 2. The air flow containing hypochlorous acid is discharged in front of the window member 102, thereby sterilizing the surrounding space. As a result, purified air can be provided to the user in front of the window member 102.

When the additional element includes a temperature change, the functional unit 5 includes, for example, an air conditioner. The air conditioner has a compressor. The air conditioner is arranged, for example, on the upstream side of the pair of blowers 4 and near the blowers 4 . The air conditioner may be housed within the housing 9. Each blower 4 sucks in cold or warm air generated by the air conditioner, generates an air flow, and blows it out from a pair of nozzle sections 2 . As a result, the user in front of the window member 102 can be provided with air at a comfortable temperature.

When the functional unit 5 includes the above-mentioned air purifying device, space sterilizing and deodorizing device, and air conditioning device, turning on and off the power supply thereof, adjusting various parameters, etc. can be performed, for example, by operating the operating unit 7. It is possible. Note that the control unit 6 may centrally control the functional section 5. The operation of the functional unit 5 may be controlled in conjunction with the operation of the blower 4 under the control of the control unit 6.

By providing the functional unit 5 in this manner, the combined airflow G1 to which additional elements are added can be provided to the user.

In this embodiment, on the flow path of the air flow to the pair of nozzle parts 2 (see arrow C1 in FIG. 3), the functional part 5, the (pair of) blowers 4, and the (pair of) nozzle parts 2, in this order, These are arranged (see FIG. 3). Therefore, compared to, for example, a case where the functional part 5 is disposed between the blower 4 and the nozzle part 2, the replacement work regarding the functional part 5 (for example, the replacement work of an air freshener, a filter, etc.) becomes easier.

A power cord is led out from the housing 9, and the plug of the power cord is connected to, for example, an outlet in the facility to provide an operating power source for driving the blower 4, control unit 6, functional section 5, etc. Can be supplied. The casing 9 may be placed, for example, inside the outer wall, or may be installed in a predetermined space indoors (may be in the ceiling or under the floor), and only the flow path C2 may be placed inside the outer wall. .

The ventilation system 1 may further include a speaker section configured to emit music or other sounds from around the window member 102 toward the front. The operation of the speaker section may be controlled in conjunction with the operation of the blower 4 under the control of the control unit 6. The speaker section may be, for example, a so-called parametric speaker that uses ultrasonic waves to provide directivity. Since the speaker section is a parametric speaker, it is possible to provide sound (sound) in addition to airflow to a user who is in a local space (near the window member 102).

(2.4) Combined Air Flow The combined air flow G1 provided by the blower system 1 will be described below with reference to FIGS. 2, 4A to 4D, and 5A to 5D.

As described above, the pair of nozzle parts 2 collide the airflows blown out from each in a direction approaching each other, and form a confluence that flows away from the one surface 101 along the direction intersecting the one surface 101 of the window member 102. Generate an air flow G1.

In this embodiment, the pair of nozzle parts 2 are set so that the collision point P1 where the air flows collide with each other is located approximately on the imaginary line connecting the pair of air outlets 20. At the collision point P1, the airflows collide with each other, so that the airflows are divided approximately in the front-rear direction. However, since the window member 102 is present at the rear, the airflow flowing backward from the collision point P1 hits one surface 101 and can mix with the airflow flowing forward from the collision point P1. As a result, as shown in FIGS. 4D and 5D, a substantially linear combined airflow G1 perpendicular to the one surface 101 is generated toward the front of the one surface 101.

Note that FIGS. 5A to 5D are thermal images viewed from above of the combined airflow G1 provided by the ventilation system 1 when the air volume balance (ratio) of the airflows blown out from the left and right nozzle parts 2 is different. (Experimentally, the air flow is warm air). 4A to 4D show simulation results of the combined air flow G1 viewed diagonally from the front.

The left and right air volume ratio in FIG. 5A is 0.4:1, and FIG. 4A is a simulation result at the same ratio. The left and right air volume ratio in FIG. 5B is 0.6:1, and FIG. 4B is a simulation result at the same ratio. The left and right air volume ratio in FIG. 5C is 0.8:1, and FIG. 4C is a simulation result at the same ratio. The left and right air volume ratio in FIG. 5D is 1:1, and FIG. 4D is a simulation result at the same ratio. In other words, here, as an example, the air volume of the air flow from the left nozzle part 2A is changed in the range of "40" to "100" with respect to the air flow volume of "100" from the right nozzle part 2B. There is.

From these drawings, it can be easily understood that by changing the air volume ratio of the air flows blown out from the left and right nozzle sections 2, the position of the collision point P1 in the arrangement direction D1 changes. That is, as the air volume of one of the left and right nozzle parts 2 decreases relative to the air volume of the other, the collision point P1 shifts to the one side. As the collision point P1 moves, the direction of the combined airflow G1 also changes. That is, when the left and right air volume ratio is 1:1, the direction of the combined air flow G1 is perpendicular to one surface 101 (see FIGS. 4D and 5D), but if the air volume on one side (left side in the figure) is As it descends, it begins to tilt to one side, and the angle of inclination with respect to one surface 101 becomes smaller.

As described above, in this embodiment, the combined airflow G1 caused by the collision of the airflows blown out from the pair of nozzle parts 2 flows away from the one surface 101. Therefore, for example, if a user is present in front of one surface 101, the user can experience the combined airflow G1. As a result, it is possible to improve the sensation of the airflow compared to, for example, the case where the airflow blown out from a single nozzle section is directly provided to a person.

In particular, the collision point P1, which is the source of the combined air flow G1, is located in front of the window member 102. In other words, even though the air outlet is not present on the window member 102, the combined air flow G1 can be experienced as if it were blowing out from the window member 102, with a sense of reality close to natural wind. In other words, a user who is present in front of the window member 102 can experience a simulated feeling of outside air even if the window member 102 is not open. Furthermore, the external view seen through the window member 102 is not obstructed by the air outlet of the nozzle portion.

In addition, the airflow control unit 3 (here, the blower 4 and the control unit 6) adjusts the position where the airflows collide with each other so that the direction of the combined airflow G1 changes, so the sensation of the airflow is further improved. .

For example, if the control unit 6 determines that the user is present in the first area R1 based on the position determination based on the detection result of the human sensor 11, the control unit 6 lowers the left air volume and directs the combined air as shown in FIG. 5A or FIG. 5B. The direction of the flow G1 may be changed to diagonally forward to the left. In this case, by interlocking with the detection result of the human sensor 11, the sensation of the combined air flow G1 is further improved.

Furthermore, on a windy day outside the actual facility, the control unit 6 may control the blower 4 to increase the air volume of the combined air flow G1 by automatically adjusting the air volume based on the detection result of the air volume sensor 12. . Even if the window member 102 is not open, the user can experience strong winds equivalent to those outside the facility while watching street trees and the like sway due to the wind through the window member 102 inside the facility. In this case, the sensation of the combined airflow G1 is further improved.

(3.1) Modification example 1
Hereinafter, the ventilation system 1A of Modification 1 will be described with reference to FIGS. 6 to 9B. However, the same reference numerals are given to the constituent elements that are substantially common to the air blowing system 1 of the basic example, and the explanation thereof will be omitted as appropriate.

The ventilation system 1A of the modified example 1 differs from the ventilation system 1 of the basic example in that the airflow control unit 3 applies a second change to the airflow.

The second change is a change in which the airflow blown out from at least one of the pair of nozzle parts 2 is divided into a plurality of airflows. The airflow control unit 3 of Modification 1 has a flow dividing structure 30 (see FIGS. 7A and 7B) for applying the second change. The dividing structure 30 is provided in the nozzle portion 2 and divides the airflow into a plurality of airflows.

In the following, it is assumed that the second change is applied to the airflow blown out from both of the pair of nozzle parts 2. Therefore, the flow dividing structure 30 is provided in each of the pair of nozzle parts 2. However, the second change may be applied only to the airflow blown out from one of the pair of nozzle sections 2, and the flow dividing structure 30 may be provided on one nozzle section 2.

The airflow control unit 3 of the first modification applies at least the second change of the first change and the second change of the basic example. In other words, in the first modification, the first variation of the basic example is not essential. In the following, it is assumed that both the first change and the second change are provided.

The flow dividing structure 30 will be specifically explained below. The flow dividing structure 30 is arranged near the air outlet 20 inside each nozzle section 2 . The flow dividing structure 30 is configured to form an intermittent air flow in the vertical direction. The flow dividing structure 30 has a plurality of (here, five) openings 31 and a plurality of (here, four) wall portions 32. Note that in FIGS. 7A and 7B, only the left nozzle portion 2A is illustrated.

The plurality of openings 31 are lined up along one surface 101 (in the vertical direction here). The plurality of openings 31 are each configured to emit a plurality of airflows. As shown in FIG. 7A, each opening 31 has an elongated rectangular shape in the vertical direction when the air outlet 20 is viewed from the front. Note that the above-mentioned opening shape of the opening portion 31 is merely an example, and is not particularly limited, and may have a circular shape, for example.

Each wall portion 32 is interposed between two adjacent openings 31 in the plurality of openings 31 . The plurality of wall portions 32 have a rectangular shape that is elongated in the vertical direction when the air outlet 20 is viewed from the front. Each wall portion 32 is a rib formed integrally with the inner surface of the nozzle portion 2 . As shown in FIG. 7B, a cross section of each wall portion 32 taken near the air outlet 20 along a direction perpendicular to the thickness direction of the nozzle portion 2 has a rectangular shape. Specifically, the cross sections of the two central walls 32 of the four walls 32 have a substantially trapezoidal shape that widens as they approach the air outlet 20. On the other hand, the cross sections of the two walls 32 on both the upper and lower sides of the four walls 32 have a substantially parallelogram shape with the long sides inclined along the inner circumferential surface of the nozzle part 2. . Note that the above-described cross-sectional shape of the wall portion 32 is merely an example, and is not particularly limited.

The airflow toward the outlet 20 hits the plurality of walls 32 and can be discharged from the plurality of openings 31 as a plurality of airflows at a substantially uniform air volume.

Further, the pair of nozzle portions 2 of Modification 1 are arranged diagonally forward with respect to the one surface 101 so that the air flows collide with each other at a position a predetermined distance W1 (see FIG. 6) forward from the one surface 101. configured to emit multiple airflows. Here, a first inner surface 221 and a second inner surface 222 (see FIG. 6) that face each other inside the second end 22 of each nozzle part 2 are at a predetermined angle with respect to one surface 101 of the window member 102. It is tilted diagonally forward. The predetermined angles in the pair of nozzle portions 2 are approximately equal to each other.

The predetermined angle is, for example, 45 degrees. The predetermined angle is not particularly limited as long as it is less than 90 degrees (that is, the airflows from the pair of nozzle parts 2 do not flow forward in parallel to each other). However, in consideration of stable formation of the combined airflow G1, it is desirable that the predetermined angle be within a range of 15 degrees or more and 45 degrees or less. Note that by setting the predetermined angle such that the collision point P1 is located between the surface 101 and the user within the detection area R0, the sensation of the combined air flow G1 is further improved. Conversely, the predetermined angle may be set so that the collision point P1 is located further forward than the detection area R0, and in this case, it is surrounded by the air flow from the pair of nozzle parts 2 and the one surface 101. This allows the user to experience a closed space.

By the way, FIGS. 8A and 8B show the state of air flow in the ventilation system 1X, which is a comparative example. The ventilation system 1X of the comparative example does not have the flow dividing structure 30 similarly to the ventilation system 1 of the basic example. However, the pair of nozzle parts 2X of the comparative example are configured to emit a plurality of air streams obliquely forward at an inclination angle of 45 degrees with respect to the one surface 101, similarly to the blower system 1A of the first modification. .

The air blowing system 1X of the comparative example does not have the flow dividing structure 30, so that one of the air flows from the pair of nozzle parts 2X swirls around the other, so that they flow together in a swirling manner, and the air flows straight into the front. It can be seen from FIGS. 8A and 8B that the air flow G1 is not formed. This is because the air pressure between the two air streams is lower than the surrounding air pressure, and the two air streams are drawn into a negative pressure space.

On the other hand, the ventilation system 1A of Modification 1 has the flow dividing structure 30, so that the wall portion 32 can separate two adjacent airflows in the plurality of airflows discharged from the plurality of openings 31, as shown in FIG. 9B. An attraction part 33 is created in which air is attracted during the airflow. In other words, due to the existence of the attraction part 33, the air in the surrounding space SP1 flows into the negative pressure space SP2 between the two air flows through the attraction part 33, and the air pressure in the space SP1 and the space SP2 are reduced. Balance with air pressure is maintained. As a result, turbulence of the combined airflow G1 due to negative pressure can be suppressed. In other words, even if the collision point P1 is set at a predetermined distance W1 forward from the surface 101, it is possible to stably form a straight forward merged airflow G1 (see FIG. 9A). ).

(3.2) Modification 2
Hereinafter, a ventilation system 1B according to modification 2 will be described with reference to FIG. 10A. However, the same reference numerals are given to the constituent elements that are substantially common to the air blowing system 1 of the basic example, and the explanation thereof will be omitted as appropriate. Note that FIG. 10A schematically shows only the air outlet 20 and its surrounding area in one of the pair of nozzle parts 2.

The ventilation system 1B of the modification 2 is common to the ventilation system 1 of the basic example in that the airflow control unit 3 applies the first change to the airflow, but the airflow control unit 3 can change the air volume. This differs from the ventilation system 1 of the basic example in that it further includes an opening/closing mechanism Y1 (see FIG. 10A).

In modification 2, each of the pair of nozzle parts 2 has one or more (here, one) louver 8 that controls the direction of airflow, and this louver 8 also functions as the opening/closing mechanism Y1. Function.

The louver 8 has a rectangular strip shape that is elongated in the vertical direction. The louver 8 has shaft portions at its upper and lower ends, and is attached to the main body 200 of the nozzle portion 2 via these shaft portions so as to be exposed from the air outlet 20 of the nozzle portion 2. Further, the louver 8 is rotatably supported within a predetermined angular range with respect to the main body 200 of the nozzle portion 2 via these shaft portions. The louver 8 is rotatable, for example, between a first position where its thickness direction generally coincides with the front-back direction and a second position where its thickness direction generally coincides with the left-right direction.

The ventilation system 1B includes a drive unit that rotates the louver 8 between a first position and a second position under the control of the control unit 6. The louver 8 can change the wind direction by being rotated by the drive unit. By rotating the louver 8 to a position forming a predetermined angle with respect to one surface 101 of the window member 102, the airflow may be emitted diagonally forward as in the first modification. Such airflow direction control further improves the sensation of airflow.

The louver 8 also functions as the opening/closing mechanism Y1 as described above. The louver 8 suppresses (changes) the volume of airflow by, for example, being rotated to the extent that it almost blocks the air outlet 20 . Since the airflow control unit 3 includes the opening/closing mechanism Y1 in this manner, the air volume of the combined airflow G1 can be changed, and the sensation of the airflow is further improved. Note that for the second modification, it is not essential that the control unit 6 (airflow control section 3) in the basic example adjusts the rotational speed of the motor to control the air volume of the blower 4.

Further, for the second modification, a drive unit that rotationally drives the louver 8 under automatic control is not essential, and the louver 8 may be rotated by receiving a manual operation from the user.

Furthermore, the rotation axis of the louver 8 is not limited to being along the vertical direction. FIG. 10B shows another example of modification 2 (louver 8A). The rotation axis of the louver 8A is along the front-rear direction. The plurality of louvers 8A are arranged in the vertical direction. In the example of FIG. 10B, each louver 8A is rotatably supported within a predetermined angular range with respect to the main body 200 of the nozzle section 2 via shaft portions at both ends in the front-rear direction. In the example of FIG. 10B as well, the air volume of the combined air flow G1 can be changed, and the sensation of the air flow can be further improved.

(3.3) Modification 3
Hereinafter, a ventilation system 1C according to modification 3 will be described with reference to FIG. 11A. However, the same reference numerals are given to the constituent elements that are substantially common to the air blowing system 1 of the basic example, and the explanation thereof will be omitted as appropriate.

In seasons such as winter, descending cold air H1 (see FIG. 11A) may occur on the front side (indoor side) of the window member 102 near the window member 102 whose back side is exposed to the outside air (cold draft phenomenon). In addition, the cold draft phenomenon may impair indoor temperature comfort.

Therefore, the blowing system 1C of the third modification differs from the blowing system 1 of the basic example in that the pair of nozzle parts 2 are provided in the upper and lower frame pieces 105 instead of the left and right frame pieces 104. One of the pair of nozzle parts 2 in the third modification (here, the lower nozzle part 2) directs the airflow from bottom to top so as to face the descending cold air generated in front of one surface 101 of the window member 102. Speech out. Note that here, regarding the air volume ratio of the pair of nozzle parts 2, it is specified that the air volume of one (here, the lower nozzle part 2) is larger than the air volume of the other (here, the upper nozzle part 2). . According to this configuration, cold drafts in the window member 102 can be suppressed.

The ventilation system 1C of modification 3 may further include a temperature sensor as the sensor Z1. The control unit 6 may automatically start the operation of the blower 4 based on the temperature information obtained from the temperature sensor so as to suppress cold draft.

Although a certain effect of suppressing cold draft can be obtained even with a configuration in which the air flow is blown out from a pair of left and right nozzle parts 2 as in the ventilation system 1 of the basic example, modification example 3 has a higher effect. is obtained.

(3.4) Modification example 4
Hereinafter, a ventilation system 1D according to modification 4 will be described with reference to FIG. 11B. However, the same reference numerals are given to the constituent elements that are substantially common to the air blowing system 1 of the basic example, and the explanation thereof will be omitted as appropriate.

In the basic example, the ventilation system 1 is applied to a ventilation window 100. The ventilation system 1D of the modification 4 differs from the ventilation system 1 of the basic example in that it is applied to a so-called digital signage 150.

Digital signage 150 is an information medium that displays various images and characters. In the example of FIG. 11B, the digital signage 150 is embedded in a pillar 160 of a station building, an underground mall, a department store, or the like. The digital signage 150 includes a ventilation system 1D, a display unit 170 for displaying at least one of images and text, and a housing frame 180 that accommodates or holds these. Here, the structure X1 is the display section 170.

The display unit 170 is realized by, for example, a liquid crystal display or an organic EL (Electro Luminescence) display. The pair of nozzle parts 2 of the air blowing system 1D are arranged so that they each blow out airflow along the one surface 101 from both sides (in this case, both left and right sides) of the one surface 101 of the display part 170.

According to this configuration, the sensation of airflow for the person (user) viewing the video displayed on the display unit 170 is improved.

In particular, in the fourth modification, the control unit 6 is configured to acquire video information from a video processing section that generates video and outputs it to the display section 170. The control unit 6 is configured to adjust the air volume of the blower 4 according to the video information from the video processing section (in cooperation with the video information). For example, when presenting a scene that gives an image of a refreshing feeling or an image related to a product advertisement, by changing the air volume of the blower 4, the refreshing feeling given to people near the digital signage 150 can be increased by changing the combined air flow G1. can be improved by

Furthermore, when presenting a video related to an advertisement for food, a restaurant, etc., it is possible to alert people passing by the digital signage 150 to the advertisement by blowing out an air stream with a scent (for example, a scent of citrus fruits, etc.). can. As a result, purchasing intentions are further promoted.

In particular, in Modification 4, when the human sensor 11 described in the basic example detects a person passing by the digital signage 150, it starts blowing air, thereby reducing unnecessary power consumption. The combined air flow G1 can be provided at appropriate timing.

Note that the control unit 6 may also have the function of a video processing section. In addition to the digital signage 150, the ventilation system 1D may be applied to a gaming machine having a display section.

(3.5) Other Modifications In the basic example, the window frame 103 is formed into a rectangular frame shape so as to surround the four sides of the window member 102, which is a rectangular plate shape. However, the window member 102 is not limited to a rectangular plate shape, and may be a polygonal plate shape other than a rectangle, or a circular plate shape. The window frame 103 may also have a polygonal frame shape other than a rectangle, or a circular frame shape, depending on the shape of the window member 102. Further, the window member 102 and the window frame 103 may have shapes that are dissimilar to each other.

Regarding cooperation with the natural environment in the basic example, the ventilation system 1 blows out a breeze-like air flow in the early morning when the sun begins to rise, gradually increases the temperature of the air flow as the sun rises, and in the evening An air stream containing cold air may be blown out. In this case, the ventilation system 1 may have an illuminance sensor, a temperature sensor, etc. as the sensor Z1, and may control the airflow volume based on the detection results thereof. Air volume control may also be performed. By controlling the air volume in this way, an environment close to the natural environment can be recreated within the facility. Further, the ventilation system 1 may perform air volume control so that the combined airflow G1 has fluctuations (may be fluctuations of 1/f) similar to winds in a natural environment.

In the basic example, a configuration is adopted in which indoor air is circulated. That is, the air suction port toward the blower 4 is installed indoors in the facility. However, the inlet may be installed outside the facility to circulate outside air. However, when performing outside air circulation, it is desirable that the functional unit 5 has an air cleaning device having a dust collection filter that collects pollen, dust, yellow sand, and particulate matter (PM10, PM2.5, etc.).

In the basic example, the nozzle portion 2 has an inlet through which the air flow from the blower 4 is introduced is arranged at the rear end (first end 21). However, the introduction port may be provided at the lower end of the nozzle portion 2, and the nozzle portion 2 may be configured such that the air flow introduced into the nozzle portion 2 from below is blown out laterally. In this case, the dimensions of the nozzle portion 2 in the front-rear direction can be suppressed. However, with this configuration, there is a high possibility that the air volume will be uneven on both sides of the air outlet 20, so the basic example is preferable from the viewpoint of uniformity of the air volume.

The ventilation window 100 may be a so-called bay window. When the blowing window 100 is a bay window, as in the basic example, the collision point P1 of the air flow blown straight in the left and right direction from the pair of nozzle parts 2 is a certain distance (for example, about 30 cm) from one surface 101 of the window member 102. It can be in a remote location. In this case, since a backward airflow is generated, there is a possibility that a stable forward merged airflow G1 cannot be obtained. Therefore, when the ventilation window 100 is a bay window, it is desirable that the ventilation system 1 has the flow dividing structure 30 of the first modification.

The ventilation system 1 in the basic example may further include a pair of upper and lower nozzle sections in addition to the pair of left and right nozzle sections 2. The combined airflow G1 may be formed by collision of airflows from the upper, lower, right, and left (four directions). The pair of upper and lower nozzle parts may have a different structure (dimensions and shape) from the pair of left and right nozzle parts 2.

The end surface of the second end portion 22 (where the air outlet 20 is located) in each nozzle portion 2 is not limited to a flat surface, and may be curved in an arc shape when viewed from the front of the window member 102, for example.

In addition to the window member 102 and the display section 170, the structure X1 may also be a mirror. When the structure X1 is a mirror, the ventilation system 1 may be applied to a bathroom vanity, for example.

In the basic example, the installation location of the ventilation window 100 is assumed to be inside the facility (indoors), but the installation location of the ventilation window 100 may be outside the facility (outdoors). But that's fine. Examples of moving objects may include automobiles, trains, airplanes, ships, construction machinery, amusement park rides, and the like. For example, when the window is applied to a train window that cannot be opened or closed, the air flow blown out from the nozzle part 2 on the side in the direction of train movement is made larger than the air volume from the nozzle part 2 on the opposite side. You can experience a simulated feeling of the wind hitting your face.

When the functional unit 5 includes an air conditioner, the blower 4 and the air conditioner may be integrated. In other words, the air conditioner may function as the blower 4.

In addition to the cold draft described in Modification 3, there is a high possibility that condensation will occur on one surface 101 of the front side (indoor side) of the window member 102 whose back side is exposed to the outside air in seasons such as winter. . However, dew condensation can also be suppressed by the airflow from the left and right pair (or upper and lower pair) of nozzle parts 2. When suppressing dew condensation, an air flow containing cold air may be blown out so as to reduce the temperature difference between outdoors and indoors. On the other hand, when there are people in the room, there is a high possibility that the comfort of the indoor temperature will be impaired by the cold air, so the air volume may be increased instead of the cold air, and even in that case, the effect of suppressing dew condensation can be obtained.

In the basic example, the nozzle part 2 is separate from the window frame 103, and a part of the nozzle part 2 is housed inside the window frame 103. However, the nozzle portion 2 and the window frame 103 may be formed integrally. For example, the window frame 103 may also have the function of the nozzle section 2.
