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

As shown in FIG. 1, the ventilation system 1 according to the first embodiment includes a pair of nozzle portions 2. Each of the pair of nozzle portions 2 blows air flow from both sides of one surface 101 of the structure X1 (both left and right sides in FIG. 1) along one surface 101. The term "along one surface 101" as used in the present disclosure includes not only "parallel to one surface 101" but also "toward diagonally forward of one surface 101". Further, in the first embodiment, it is assumed that the number of the nozzle portions 2 is two, but three or more may be provided, and the ventilation system 1 includes, for example, two sets of a pair of nozzle portions 2 (four in total). You may.

Here, as shown in FIG. 2, the pair of nozzle portions 2 collide with each other in the directions of air blown out from each other, and flow away from the one surface 101 along the direction intersecting the one surface 101. It is configured to generate a confluent air flow G1. Here, the "direction intersecting the one surface 101" means a direction along a line passing one point on the one surface 101 in the thickness direction of the structure X1. That is, the "direction intersecting the one surface 101" refers to the direction along the line intersecting the line along the alignment direction D1 in FIG. 2, and is not only the direction along the line orthogonal to the line along the alignment direction D1. Includes the direction along the intersecting lines at an angle, that is, diagonally forward of one surface 101.

According to this configuration, the confluent air flow G1 generated by the collision of the air flows blown out from the pair of nozzle portions 2 flows away from the one surface 101. Therefore, for example, if a person is present in front of one surface 101, the person can experience the confluence G1. Therefore, for example, the air flow system 1 according to the first embodiment can provide an air flow with a sense of presence, as compared with the case where the air flow blown from a single nozzle portion is provided to a person as it is. As a result, the ventilation system 1 according to the first embodiment can improve the sensation of air flow.

In the first embodiment, it is assumed that the structure X1 is a window member 102 (see FIGS. 1 and 2) as an example.

The blower window 100 according to the first embodiment includes a blower 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 portions 2 are respectively arranged inside the pair of frame pieces 104 so that the outlet 25 for blowing out the air flow is exposed from the window frame 103.

In the first embodiment, the ventilation window 100 is installed on a higher floor where it is relatively difficult to open and close the window (window member 102) in a facility such as a condominium (apartment house), a hotel or an office building, for example. It is assumed that it will be done. Further, in the first embodiment, the ventilation window 100 assumes, for example, a window in which the window member 102 is fixed to the window frame 103 and cannot be opened or closed. However, the window member 102 may be supported so as to be openable and closable with respect to the window frame 103. In addition to the above facilities, the ventilation window 100 can be installed in detached houses, theaters, movie theaters, public halls, amusement parks, complex facilities, restaurants, department stores, schools, inns, hospitals, nursing homes, kindergartens, and libraries. , Museums, art galleries, underground streets, stations or airports, etc.

According to this configuration, it is possible to provide a blower window 100 provided with a blower system 1 capable of improving the sensation of air flow. In the following, the window member 102 (structure X1) will be described as one of the components of the ventilation window 100, but the window member 102 is not an essential component for the ventilation window 100. For example, at the installation site of the ventilation window 100 or the like, the window member 102 according to the request of the user or the like may be appropriately provided afterwards.

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

(2.1) Overall configuration As described above, the ventilation window 100 is applied as a window provided on an outer wall of, for example, a high floor in a facility. In the facility, a person (hereinafter referred to as "user") on the window side of the ventilation window 100 can view the outside view of the outside of the facility through the ventilation window 100.

FIG. 1 is an external perspective view of the ventilation window 100 as seen from the inside of the facility in a state where the ventilation window 100 is installed on the wall. FIG. 2 is a cross-sectional view taken along the line AA in FIG. Further, FIG. 3 is a block diagram showing the configuration of the ventilation system 1. In the following, the vertical and horizontal directions when the blower window 100 is viewed from the front in a room with the blower window 100 installed on the wall (see FIG. 1) are referred to as the vertical direction and the horizontal direction of the blower window 100. To do. Further, the indoor side of the blower window 100 is the front side (front side) of the blower window 100, and the outside view side of the blower window 100 is the rear side of the blower window 100. However, the provision of these directions is not intended to limit the direction of use of the blower window 100.

The blower window 100 has a rectangular shape that is long in the vertical direction as a whole. As described above, the ventilation window 100 includes a ventilation system 1, a window member 102 (structure X1), and a 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 material having translucency. The window member 102 is, for example, transparent, but may be translucent. 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 intended use of the blower window 100. Further, the window member 102 is not only composed of one plate material, but may be composed of two or more plate materials arranged side by side in the thickness direction (for example, double glazing or the like).

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

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

Each frame piece 104 has a storage space inside for accommodating a part of the nozzle portion 2 (described later) of the ventilation system 1. In particular, each frame piece 104 is provided with a slit-shaped through hole 106 for exposing the outlet 25 of the nozzle portion 2 to the outside. The through hole 106 connects the accommodation space and 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 side surface 107 (opposing surface of the pair of frame pieces 104) of the corresponding frame piece 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 side surface 107 in which the through hole 106 is provided.

(2.3) Blower system As described above, the blower system 1 includes a pair of nozzle portions 2 (see FIGS. 1 to 3). Further, as shown in FIG. 3, the blower system 1 includes one or more blowers 4 (two in the first embodiment), a control unit 6, a functional unit 5, an operation unit 7, and one or more (implementation). The second sensor Z1 in the first embodiment is further provided.

The two blowers 4 (fans) are arranged on the upstream side of the pair of nozzles 2 so as to generate an air flow and individually send the generated air flow to the pair of nozzles 2 on a one-to-one basis. It is composed of. Specifically, each blower 4 generates an air flow under the control of, for example, the control unit 6 and sends it to one of the pair of nozzle portions 2 via the flow path C2 (see FIG. 3). The flow path C2 is composed of a pair of ducts, each of which spatially connects one blower 4 and one nozzle portion 2. That is, since there are two blowers 4 in the first embodiment, the pair of ducts constituting the flow path C2 are configured to connect the two blowers 4 and the two nozzles 2 one-to-one.

The number of blowers 4 may be one, and in this case, the ducts constituting the flow path C2 may be configured to bifurcate in the middle in order to individually deliver the air flow to the pair of nozzle portions 2. .. In this case, it is desirable that a damper for adjusting the air volume is provided 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 portions 2 can be individually adjusted.

Each blower 4 is, for example, a sirocco fan that generates an air flow containing a large amount of a linear component as compared with a swirling component. A functional unit 5 is arranged around the blower 4, and the blower 4 sucks in air including an additional element (described later) added by the functional unit 5 to generate an air flow. The blower 4 is not limited to the sirocco fan, but may be a propeller fan. The ventilation system 1 of the first embodiment is configured to circulate the air in the room. Therefore, the air suction port toward the blower 4 is installed in the room.

Each blower 4 can adjust the rotation speed of the motor and appropriately change the air volume by, for example, inverter control. For example, the operation unit 7 is provided with a volume for adjusting the air volume, and the user can appropriately adjust the air volume of the blower 4 at the installation site of the blower window 100. Further, the control unit 6 can automatically change the air volume of the blower 4.

In the first embodiment, the blower 4 together with the control unit 6 constitutes a "air flow control unit 3" in which the blower 4 gives a change (first change) regarding the air volume of the air flow to the air flow blown out from the pair of nozzle units 2. To do. In other words, the airflow system 1 includes an airflow control unit 3 that gives a first change to the airflow blown from at least one of the pair of nozzle units 2, and the airflow control unit 3 is a blower 4 capable of changing the air volume. Includes. When there are two blowers 4, the first change may be applied to the air flow blown out from the corresponding nozzle portion 2 through only one blower 4. In short, it is not essential that the airflow control unit 3 gives the first change to the air flow blown out from both of the pair of nozzle units 2. Further, when the damper for adjusting the air volume is arranged in the middle of the duct, the damper can also be one of the components of the airflow control unit 3.

In the first embodiment, each of the pair of nozzle portions 2 assumes, for example, a molded product of synthetic resin, but is not particularly limited. Each of the pair of nozzle portions 2 may be a molded product of metal (for example, aluminum or the like). The pair of nozzle portions 2 are configured to blow air flow from both sides of one surface 101 of the window member 102 which is the structure X1 (both left and right sides in the first embodiment) along the one surface 101.

The pair of nozzle portions 2 are arranged in the left-right direction (see the arrangement direction D1 in FIG. 2). The pair of nozzle portions 2 have substantially the same shape and the same dimensions, and are arranged so as to be plane-symmetrical in the left-right direction. Each nozzle portion 2 has a flat hollow square tube shape in which the end faces of both ends of the first end portion 21 and the second end portion 22 are open. Hereinafter, when the pair of left and right nozzle portions 2 are described separately from each other, the left nozzle portion 2 may be referred to as a nozzle portion 2A, and the right nozzle portion 2 may be referred to as a nozzle portion 2B.

As shown in FIG. 1, each nozzle portion 2 gradually increases in vertical dimension from the first end portion 21 to the second end portion 22, and when viewed along the thickness direction thereof, the nozzle portion 2 gradually increases in size. It has a substantially triangular shape as a whole. Further, each nozzle portion 2 extends from the first end portion 21 to the vicinity of the second end portion 22 along the front-rear direction, and the second end portion 22 is bent so as to face the other nozzle portion 2. (See Fig. 2).

An introduction port 23 (see FIG. 1) into which an air flow from the upstream side (blower 4 side) can be introduced is provided on the end surface of the first end portion 21, and a nozzle portion 2 is provided on the end surface of the second end portion 22. An air outlet 25 (see FIG. 2) for blowing out the air flow introduced therein is provided. The outlets 25 of the pair of nozzle portions 2 face each other in the alignment direction D1. The internal flow path 24 in which the air flow flows from the introduction port 23 to the air outlet 25 in each nozzle portion 2 is bent in a substantially L shape when viewed in the vertical direction (see FIG. 2). In other words, each of the pair of nozzle portions 2 has an outlet 25 for blowing an air flow along one surface 101 of the window member 102. The outlet 25 has a slit shape whose longitudinal direction is along one surface 101. In the first embodiment, the longitudinal direction of the outlet 25 is the vertical direction.

Similar to the outer shell of the nozzle portion 2, the internal flow path 24 gradually increases in vertical dimension from the first end portion 21 to the second end portion 22. The air flow passing through the internal flow path 24 can be blown out from the outlet 25 with a substantially uniform air volume in the vertical direction.

The pair of nozzle portions 2 configured in this way are respectively arranged inside the pair of frame pieces 104 so that the outlet 25 for blowing out the air flow is exposed from the through hole 106 of the window frame 103. In the first embodiment, of each nozzle portion 2, only the second end portion 22 and its peripheral portion are housed in the corresponding frame piece 104, and the other portions including the first end portion 21 are framed. It is held by the window frame 103 in a state of protruding from the back side of the piece 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 unit 3" that gives the first change. When a damper for adjusting the air volume is arranged 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 the housing 9 (see FIG. 3) together with the blower 4, for example. The control unit 6 has, for example, a computer system having a processor and memory. Then, when the processor executes the program stored in the memory, the computer system functions as the control unit 6. The program executed by the processor is assumed to be pre-recorded in the memory of the computer system here, but may be recorded in a non-temporary recording medium such as a memory card and provided, or a telecommunications line such as the Internet. May be provided through.

The operation unit 7 receives an operation input from the outside (user). The operation unit 7 is provided, for example, on a wall surface or the like in the facility. The user can turn on and off the power of the ventilation system 1 by operating the operation unit 7. When the operation unit 7 receives the operation of turning on the power, the control unit 6 starts driving the blower 4. Further, the user can adjust the air volume of each blower 4 by operating the volume for adjusting the air volume of the operation unit 7. When the control unit 6 receives an operation for adjusting the air volume by the operation unit 7, the control unit 6 changes the air volume of the blower 4 according to the operation. The operation unit 7 may be a remote controller, in which 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.

As shown in FIG. 3, the two sensors Z1 are, for example, a motion sensor 11 and an air volume (wind speed) sensor 12. Each sensor Z1 is connected to the control unit 6 by wire (or wirelessly) so as to be able to communicate with each other. Each sensor Z1 outputs an electric signal to the control unit 6. The control unit 6 controls the blower 4 according to the electric signal acquired from each sensor Z1 to change the air volume of the air flow.

The motion sensor 11 has, for example, the window frame 103 or the window frame 103 so that the 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 in the vicinity. For example, the motion sensor 11 detects a light ray (heat ray) radiated from the user's human body existing in the detection area R0 in front of the window member 102, includes the detection result in an electric signal, and outputs the detection result to the control unit 6. To 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 side, a second area R2 in the center, and a third area R3 on the right side. ..

Based on the detection result of the motion sensor 11, the control unit 6 determines whether the user has entered the detection area R0 or has exited the detection area R0 (entrance / exit determination), and the user has entered the first area R1 to the third area. It is determined in which area of R3 it exists (position determination) and the like.

When the control unit 6 determines that the user has entered the detection area R0 by the entry / exit determination, the power of the blower 4 may be turned on to automatically start blowing. Further, when the control unit 6 determines that the user has left the detection area R0 by the entry / exit determination, the power of the blower 4 may be turned off to automatically stop the blowing.

Further, the control unit 6 automatically adjusts the air volume of the blower 4 so that the wind direction of the confluent air flow G1 faces the first area R1 when, for example, the user determines that the user exists in the first area R1 by the position determination. It may be configured to adjust to. In other words, the control unit 6 (air flow control unit 3) changes the air volume of the air flow so that the wind direction of the confluent air flow G1 changes according to the result of the position determination, so that the pair of nozzle units 2 can be combined. The position where the air streams collide with each other in the line-up direction D1 is adjusted. The details of the change in the wind direction of the confluence G1 will be described later.

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

Here, the control unit 6 is configured to automatically adjust the air volume of the blower 4 so as to roughly 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 according to the current air volume outside the facility at the installation site where it is difficult to open and close the windows easily, such as on the upper floors of the facility. As a result, the ventilation system 1 can reproduce a simulated environment linked with the actual natural environment in the facility.

The functional unit 5 is configured to add an additional element to the air flow blown from at least one of the pair of nozzle units 2 (both in the first embodiment). Additional elements include at least one of scent, air purification and temperature changes.

When the additional element contains a scent, the functional unit 5 has, for example, a scent presenting device containing a fragrance. The scent presenting device is arranged, for example, on the upstream side of each blower 4 and in the vicinity of the blower 4. The scent presenting device may be housed in the housing 9. Each blower 4 sucks in air containing a vaporized scent from an air freshener to generate an air flow, and blows it out from a pair of nozzle portions 2. As a result, the ventilation system 1 can provide the user in front of the window member 102 with high-quality scented air.

When the additional element includes air purification, the functional unit 5 has, for example, an air purifier. The air purifier is arranged, for example, on the upstream side of each blower 4 and in the vicinity of the blower 4. The air purifier may be housed in the housing 9. The air purifier has a dust collecting filter for collecting fine particles such as pollen in the air, a filter for deodorizing, and the like. Each blower 4 sucks in the air purified by the air purifier to generate an air flow, and blows it out from the pair of nozzles 2. As a result, the ventilation system 1 can provide purified air to the user in front of the window member 102.

Further, when the additional element includes air purification, the functional unit 5 may have, for example, a space sterilization deodorizer. The space sterilization deodorizer is arranged, for example, on the upstream side of each blower 4 and in the vicinity of the blower 4. The space sterilization deodorizer may be housed in the housing 9. Spatial sterilization deodorizers are configured to produce hypochlorous acid. Each blower 4 sucks in air containing hypochlorous acid to generate an air flow, and blows it out from a pair of nozzle portions 2. The air flow containing hypochlorous acid is released in front of the window member 102 to sterilize the surrounding space. As a result, the ventilation system 1 can provide purified air to the user in front of the window member 102.

When the additional element includes a temperature change, the functional unit 5 has, for example, an air conditioner. The air conditioner has a compressor. The air conditioner is arranged, for example, on the upstream side of each blower 4 and in the vicinity of the blower 4. The air conditioner may be housed in the housing 9. Each blower 4 sucks in the cold air or warm air generated by the air conditioner to generate an air flow, and blows it out from the pair of nozzle portions 2. As a result, the ventilation system 1 can provide air at a comfortable temperature to the user who is in front of the window member 102.

When the functional unit 5 has the above-mentioned air purifier, space sterilization deodorizer, and air conditioner, the power on / off and adjustment of various parameters can be performed by, for example, operating the operation unit 7. Is. The control unit 6 may centrally control the function unit 5. The operation of the functional unit 5 may be controlled so as to be linked to the operation of the blower 4 under the control of the control unit 6.

By providing the functional unit 5 in this way, the ventilation system 1 can provide the user with the confluent air flow G1 to which the additional element is added.

In the first embodiment, the functional unit 5, the blower 4 (s) and the nozzles (s) are on the flow path C1 of the air flow to the pair of nozzles 2 (see the arrow C1 in FIG. 3). These are arranged in the order of part 2 (see FIG. 3). Therefore, for example, as compared with the case where the functional unit 5 is arranged between the blower 4 and the nozzle unit 2, the replacement work (for example, the replacement work of the air freshener, the filter, etc.) related to the functional unit 5 becomes easier.

A power cord is led out to the housing 9, and a plug of the power cord is connected to, for example, an outlet in the facility to supply an operating power source for driving the blower 4, the control unit 6, the functional unit 5, and the like. Can be done. The housing 9 may be arranged inside the outer wall, for example, or may be installed in a predetermined space (may be the ceiling or the floor) in the room, and only the flow path C2 may be arranged inside the outer wall. ..

The ventilation system 1 may further include a speaker unit configured to sound music or the like from the periphery of the window member 102 toward the front. The operation of the speaker unit may be controlled under the control of the control unit 6 so as to be interlocked with the operation of the blower 4. The speaker unit may be, for example, a so-called parametric speaker in which directivity is provided by using ultrasonic waves. Since the speaker unit is a parametric speaker, sound (sound) can be provided in addition to the air flow to the user who is in a local space (near the window member 102).

(2.4) Confluence Airflow Hereinafter, the confluence airflow G1 provided by the ventilation system 1 will be described with reference to FIGS. 2, 4A to 4D, and FIGS. 5A to 5D.

4A to 4D and 5A to 5D are diagrams for explaining the confluence air flow G1 when the air volume balance is adjusted by the ventilation system 1.

As described above, the pair of nozzle portions 2 collide with each other in the direction of approaching each other, and merge to flow away from the one surface 101 along the direction intersecting the one surface 101 of the window member 102. An air flow G1 is generated.

In the first embodiment, the pair of nozzle portions 2 are set so that the collision point P1 at which the air streams collide with each other is substantially located on the virtual line connecting the pair of outlets 25. At the collision point P1, the air flows collide with each other, so that the air flows are generally separated in the front-rear direction. However, since the window member 102 exists behind, the air flow from the collision point P1 to the rear hits one surface 101 and can be mixed with the air flow from the collision point P1 to the front. As a result, as shown in FIGS. 4D and 5D, a substantially linear confluence air flow G1 orthogonal to the one surface 101 is generated toward the front of the one surface 101.

5A to 5D are thermal images of the confluent airflow G1 provided by the ventilation system 1 as viewed from above when the air volume balance (ratio) of the airflow blown from the left and right nozzle portions 2 is different. (Experimentally, the air flow is warm air). 4A to 4D show the simulation results of the confluence air flow G1 viewed from diagonally forward.

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. That is, here, as an example, the air volume of the air flow from the left nozzle portion 2A is changed in the range of "40" to "100" with respect to the air volume of the air flow from the right nozzle portion 2B "100". There is.

As shown in FIGS. 5A to 5D, it can be easily understood that the position of the collision point P1 in the alignment direction D1 changes by changing the air volume ratio of the air flow blown from the left and right nozzle portions 2. That is, as the air volume of one of the left and right nozzle portions 2 decreases with respect to the air volume of the other, the collision point P1 moves to the one nozzle portion 2 side. Then, as the collision point P1 moves, the wind direction of the confluent air flow G1 also changes as shown in FIGS. 4A to 4D and 5A to 5D. That is, when the left and right air volume ratio is 1: 1, the wind direction of the confluent air flow G1 is perpendicular to one surface 101 (see FIGS. 4D and 5D). As the air volume of one side (nozzle portion 2A) decreases, the wind direction of the confluent air flow G1 begins to tilt toward the one side (nozzle portion 2A), and the inclination angle with respect to one surface 101 becomes smaller.

As described above, in the first embodiment, the confluent air flow G1 due to the collision of the air flows blown out from the pair of nozzle portions 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 confluence G1. As a result, for example, it is possible to improve the sensation of the air flow as compared with the case where the air flow blown out from the single nozzle portion is provided to a person as it is.

In particular, the collision point P1 which is the source of the confluence air flow G1 exists in front of the window member 102. In other words, even though the air outlet 25 does not exist on the window member 102, it is possible to experience the confluence G1 having a realistic feeling close to the natural wind as if it were blown out from the window member 102. That is, the user who exists in front of the window member 102 can experience the wind of the outside air in a simulated manner even if the window member 102 is not open. Further, the outlet 25 of the nozzle portion 2 does not obstruct the external view seen through the window member 102.

Further, the airflow control unit 3 (the blower 4 and the control unit 6 in the first embodiment) changes the air volume of the airflow so that the direction of the confluent airflow G1 changes, so that the position where the airflows collide with each other can be determined. Because of the adjustment, the sensation of air flow is further improved.

If, for example, the control unit 6 determines that the user exists in the first area R1 by the position determination based on the detection result of the motion sensor 11, the air volume on the left is reduced and the confluent air is reduced as shown in FIG. 5A or FIG. 5B. The wind direction of the flow G1 may be changed diagonally forward to the left. In this case, by interlocking with the detection result of the motion sensor 11, the sensation of the confluent air flow G1 is further improved.

Further, on an actual windy day outside the facility, the control unit 6 may control the blower 4 so that the air volume of the confluent air flow G1 increases 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 a strong wind equivalent to that outside the facility while observing the shaking of roadside trees and the like due to the wind through the window member 102 inside the facility. In this case, the perceived feeling of the confluent air flow G1 is further improved.

(3) Modified Example The first embodiment is only one of the various embodiments of the present disclosure. The first embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved.

Can be done. A plurality of electronic circuits may be integrated on one chip, or may be distributed on a plurality of chips. The plurality of chips may be integrated in one device, or may be distributed in a plurality of devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Further, it is not essential for the control unit 6 that a plurality of functions of the control unit 6 of the ventilation system 1 are integrated in one housing, and the components of the control unit 6 are dispersed in the plurality of housings. It may be provided. On the contrary, a plurality of functions in the control unit 6 may be integrated in one housing. Further, at least a part of the functions of the control unit 6, for example, a part of the functions of the control unit 6 may be realized by a cloud (cloud computing) or the like.

(3.1) Modification 1
Hereinafter, the ventilation system 1A of the modified example 1 will be described with reference to FIGS. 6 to 9B. However, the components substantially common to the ventilation system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

FIG. 6 is a cross-sectional view of a blower window provided with the blower system 1A according to the first modification. FIG. 7A is a perspective view of the nozzle portion 2 in the modified example 1, and FIG. 7B is a cross-sectional view taken along the line BB in FIG. 7A. 8A and 8B are diagrams for explaining the confluence air flow G1 in the ventilation system 1X according to the comparative example. Further, FIGS. 9A and 9B are diagrams for explaining the confluence air flow G1 in the ventilation system 1A according to the first modification. The ventilation system 1A of the modification 1 is different from the ventilation system 1 of the basic example in that the airflow control unit 3 gives a second change to the air flow.

The second change is a change in which the air flow blown out from at least one of the pair of nozzle portions 2 is divided into a plurality of air flows. The airflow control unit 3 of the first modification has a flow dividing structure 30 (see FIGS. 7A and 7B) for imparting a second change. The flow dividing structure 30 is provided in the nozzle portion 2 to divide the air flow into a plurality of air flows.

In the first modification, the second change is applied to the air flow blown out from both of the pair of nozzle portions 2. Therefore, the flow dividing structure 30 is provided in each of the pair of nozzle portions 2. However, the second change may be applied only to the air flow blown from one of the pair of nozzle portions 2, and the diversion structure 30 may be provided only to one of the nozzle portions 2.

The airflow control unit 3 of the modified example 1 imparts at least the second change among the first change and the second change of the basic example. In other words, in the modified example 1, the first change of the basic example is not essential. In the following, it is assumed that both the first change and the second change are given.

Hereinafter, the diversion structure 30 will be specifically described. The flow dividing structure 30 is arranged in the vicinity of the outlet 25 inside each nozzle portion 2. The diversion structure 30 is configured to form an intermittent air flow in the vertical direction. As shown in FIGS. 7A and 7B, the diversion structure 30 has a plurality of (here, five) openings 31 and a plurality of (here, four) wall portions 32. In addition, in FIG. 7A and FIG. 7B, only the left nozzle portion 2A is shown.

The plurality of openings 31 are arranged along one surface 101 (vertical direction in the modified example 1). The plurality of openings 31 are configured to emit a plurality of airflows, respectively. As shown in FIG. 7A, each opening 31 opens in a long rectangular shape in the vertical direction when the air outlet 25 is viewed from the front. The above-mentioned opening shape of the opening 31 is merely an example, and is not particularly limited, and may be opened in 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 long in the vertical direction when the air outlet 25 is viewed from the front. Each wall portion 32 is a rib formed integrally with the inner side surface (22A, 22B) of the nozzle portion 2. As shown in FIG. 7B, the cross section of each wall portion 32 cut along the direction orthogonal to the thickness direction of the nozzle portion 2 near the outlet 25 has a rectangular shape. Specifically, the cross section of the two central wall portions 32 of the four wall portions 32 has a substantially trapezoidal shape that expands as it approaches the outlet 25. On the other hand, the cross section of the two wall portions 32 on the upper and lower sides of the four wall portions 32 has a substantially parallelogram shape in which the long side is inclined along the inner peripheral surface of the nozzle portion 2. .. The cross-sectional shape of the wall portion 32 is merely an example and is not particularly limited.

The air flow toward the outlet 25 hits the plurality of wall portions 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 the modification 1 is obliquely forward with respect to the one surface 101 so that the air flows collide with each other at a position separated from the one surface 101 by a predetermined distance W1 (see FIG. 6). It is configured to emit multiple airflows. Here, the first inner side surface 22A and the second inner side surface 22B (see FIG. 6) facing each other inside the second end portion 22 of each nozzle portion 2 have a predetermined angle with respect to one surface 101 of the window member 102. It is tilted diagonally forward. The predetermined angles of the pair of nozzle portions 2 are substantially 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, unless the air flows from the pair of nozzle portions 2 flow forward in parallel with each other). However, considering the stable formation of the confluence air flow G1, it is desirable that the predetermined angle is within the range of 15 degrees or more and 45 degrees or less. The predetermined angle is set so that the collision point P1 is located between the one surface 101 and the user in the detection area R0, so that the perceived feeling of the confluence air flow G1 is further improved. On the contrary, the predetermined angle may be set so that the collision point P1 is located further in front of the detection area R0, and in this case, the air flow from the pair of nozzle portions 2 and one surface 101 are surrounded. The user can experience the closed space.

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

Since the ventilation system 1X of the comparative example does not have the flow dividing structure 30, one of the air flows from the pair of nozzle portions 2X engulfs the other and mixes in a swirling manner, and the air flows linearly forward. It can be understood 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 ambient air pressure, and the two air streams are drawn into the negative pressure space.

On the other hand, since the ventilation system 1A of the modified example 1 has the flow dividing structure 30, the wall portion 32 has two adjacent two adjacent airflows in a plurality of airflows emitted from the plurality of openings 31 as shown in FIG. 9B. An attracting portion 33 is created in which air is attracted during the air flow. That is, due to the presence of the attracting portion 33, the air in the surrounding space SP1 flows into the negative pressure space SP2 between the two air streams through the attracting portion 33, and the air pressure in the space SP1 and the space SP2 The balance with the air pressure is maintained. As a result, turbulence of the confluent air flow G1 due to negative pressure can be suppressed. That is, even if the collision point P1 is set at a position separated from the surface 101 by a predetermined distance W1 in front, a linear confluence air flow G1 in the forward direction can be stably formed (see FIG. 9A). ).

(3.2) Modification 2
Hereinafter, the ventilation system 1B of the second modification will be described with reference to FIG. 10A. However, the components substantially common to the ventilation system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

FIG. 10A is a front view of the air outlet 25 in the ventilation system 1B according to the second modification. Note that FIG. 10A schematically shows only the air outlet 25 and its peripheral portion in one of the pair of nozzle portions 2.

The airflow control unit 3 of the modified example 2 is common to the airflow system 1 of the basic example in that the airflow control unit 3 gives the first change to the air flow, while the airflow control unit 3 can change the air volume. It differs from the airflow system 1 of the basic example in that it further includes an opening / closing mechanism Y1 (see FIG. 10A).

In the second modification, each of the pair of nozzle portions 2 has one or a plurality of (here, one) louvers 8 that control the wind direction of the air flow, and the louvers 8 may also serve as the opening / closing mechanism Y1. Function.

The louver 8 has a rectangular strip shape that is long in the vertical direction. The louver 8 has shaft portions at both upper and lower ends thereof, and is attached to the main body 20 of the nozzle portion 2 so as to be exposed from the outlet 25 of the nozzle portion 2 via these shaft portions. Further, the louver 8 is rotatably supported with respect to the main body 20 of the nozzle portion 2 via these shaft portions within a predetermined angle range. The louver 8 can be rotated between, for example, a first position whose thickness direction substantially coincides with the front-rear direction and a second position whose thickness direction substantially coincides with the left-right direction.

The ventilation system 1B has a drive unit (not shown) that rotationally drives the louver 8 between the first position and the second position under the control of the control unit 6. The wind direction of the louver 8 can be changed by rotating the louver 8 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 air flow may be discharged diagonally forward as in the first modification. By such wind direction control, the sensation of air flow is further improved.

The louver 8 also functions as the opening / closing mechanism Y1 as described above. The louver 8 suppresses (changes) the air volume of the air flow by rotating the louver 8 so as to substantially block the air outlet 25, for example. By including the opening / closing mechanism Y1 in this way, the airflow control unit 3 can change the air volume of the confluent airflow G1, and the perceived feeling of the airflow is further improved. For the second modification, it is not essential that the control unit 6 (air flow control unit 3) in the basic example adjusts the rotation speed of the motor to control the air volume of the blower 4.

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

Furthermore, the louver 8 is not limited to its rotation axis being along the vertical direction. FIG. 10B is a front view of the air outlet 25 in the ventilation system 1B according to another example of the modified example 2. FIG. 10B shows a louver 8A which is another example of the louver 8 according to the modified example 2. 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 angle range with respect to the main body 20 of the nozzle portion 2 via shaft portions at both ends in the front-rear direction thereof. Also in the example of FIG. 10B, the air volume of the confluent air flow G1 can be changed, and the perceived feeling of the air flow is further improved.

(3.3) Modification 3
Hereinafter, the ventilation system 1C of the modified example 3 will be described with reference to FIG. 11A. However, the components substantially common to the ventilation system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate. In the modified example 3, as an example, it is assumed that the structure X1 is the window member 102 (see FIG. 11A) as in the basic example.

In the vicinity of the window member 102 whose rear side (outside view side) is exposed to the outside air in a season such as winter, descending cold air H1 (see FIG. 11A) may be generated on the front side (indoor side) of the window member 102 (see FIG. 11A). Cold draft phenomenon). And the cold draft phenomenon can impair comfort with respect to room temperature.

Therefore, the ventilation system 1C of the modified example 3 is different from the ventilation system 1 of the basic example in that the pair of nozzle portions 2 are provided in the upper and lower frame pieces 105 instead of the left and right frame pieces 104. Then, one of the pair of nozzle portions 2 (here, the lower nozzle portion 2) of the modified example 3 has an air flow from bottom to top so as to face the descending cold air H1 generated in front of one surface 101 of the window member 102. Blow out. Here, regarding the air volume ratio of the pair of nozzle portions 2, the air volume of one (here, the lower nozzle portion 2) is defined to be larger than the air volume of the other (here, the upper nozzle portion 2). .. According to this configuration, cold draft in the window member 102 can be suppressed.

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

Even with a configuration in which an air flow is blown from a pair of left and right nozzle portions 2 as in the ventilation system 1 of the basic example, a certain effect of suppressing cold draft can be obtained, but the modified example 3 has a higher effect. Is obtained.

(3.4) Modification 4
Hereinafter, the ventilation system 1D of the modified example 4 will be described with reference to FIG. 11B. However, the components substantially common to the ventilation system 1 of the basic example are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

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

Digital signage 150 is an information medium that displays various images or characters. In the example of FIG. 11B, the digital signage 150 is embedded and arranged in a pillar 160 of a station building, an underground shopping 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 an image and characters, and a housing frame 180 for accommodating or holding these. Here, the structure X1 is a display unit 170.

The display unit 170 is realized by, for example, a liquid crystal display or an organic EL (Electroluminescence) display. The pair of nozzles 2 of the ventilation system 1D are arranged so as to blow out air flow from both sides (here, both left and right sides) of one surface 101 of the display unit 170 along one surface 101.

According to this configuration, the sensation of air flow to a person (user) who browses the image or the like displayed on the display unit 170 is improved.

In particular, in the modified example 4, the control unit 6 is configured to acquire video information from a video processing unit (not shown) that generates video and outputs it to the display unit 170. Then, the control unit 6 is configured to adjust the air volume of the blower 4 according to the video information from the video processing unit (in cooperation with the video information). For example, when presenting a scene or a video related to a product advertisement that imagines a refreshing feeling, by giving a change to the air volume of the blower 4, the refreshing feeling given to a person near the digital signage 150 is the confluence G1. Can be improved by

In addition, when presenting a video related to the announcement of food or restaurants, by blowing out an air stream with a scent (for example, the scent of citrus fruits), people who pass by the digital signage 150 are attracted by advertising. be able to. As a result, purchasing motivation and the like are further promoted.

In particular, the ventilation system 1D of the modified example 4 starts blowing out an air flow when a person passing by the digital signage 150 is detected by the motion sensor 11 described in the basic example, thereby consuming unnecessary power. It is possible to provide the confluent air flow G1 at an appropriate timing while suppressing the above.

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

(3.5) Other Modification Examples In the basic example, the window frame 103 is formed in a rectangular frame shape so as to surround the four sides of the rectangular plate-shaped window member 102. However, the window member 102 is not limited to the rectangular plate shape, and may be a polygonal plate shape other than the rectangular plate shape or a circular plate shape. The window frame 103 may also have a polygonal frame shape other than a rectangular shape 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 not similar to each other.

Regarding the cooperation with the natural environment in the basic example, the ventilation system 1 blows out an air flow like a breeze in the early morning when the sun starts to rise, gradually raises the temperature of the air flow as the sun rises, and at dusk. 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, or the like as the sensor Z1, and control the air volume of the air flow based on the detection results thereof. Further, the ventilation system 1 may control the air volume based on the current time. With such air volume control, the ventilation system related to this deformation can reproduce an environment close to the natural environment in the facility. Further, the ventilation system 1 may control the air volume so that the confluent air flow G1 has a fluctuation (may be a fluctuation of 1 / f) close to the wind in the natural environment.

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

In the basic example, the nozzle portion 2 has an introduction port 23 into which the air flow from the blower 4 is introduced is arranged at the rear end portion (first end portion 21). However, the introduction port 23 may be provided at the lower end portion of the nozzle portion 2, and the nozzle portion 2 may be configured such that the air flow introduced into the nozzle portion 2 is blown out in the lateral direction from below. The ventilation system related to this deformation can suppress the dimensions of the nozzle portion 2 in the front-rear direction. However, in this configuration, there is a high possibility that the air volume of the air flow will be uneven on both the upper and lower sides of the outlet 25, so that the basic example is desirable from the viewpoint of the uniformity of the air volume.

The ventilation window 100 may be a so-called bay window. When the blower window 100 is a bay window, the collision point P1 of the air flow blown straight from the pair of nozzles 2 in the left-right direction as in the basic example is only a certain distance (for example, about 30 cm) from one surface 101 of the window member 102. It can be in a remote position. In this case, since an air flow toward the rear is generated, there is a possibility that a stable confluence air flow G1 toward the front cannot be obtained. Therefore, when the blower window 100 is a bay window, it is desirable that the blower 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 portions in addition to the pair of left and right nozzle portions 2. The confluent air flow G1 may be formed by collision of air flows from the top, bottom, left, and right (four sides). The pair of upper and lower nozzle portions may have a structure (dimension and shape) different from that of the pair of left and right nozzle portions 2.

The end surface of the second end portion 22 (with the outlet 25) 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.

The structure X1 may be a mirror in addition to the window member 102 and the display unit 170. When the structure X1 is a mirror, the ventilation system 1 may be applied, for example, to a vanity.

In the basic example, the installation location of the ventilation window 100 is assumed to be inside the facility (indoor), but the installation location of the ventilation window 100 may be outside the facility (outdoor), and the ventilation window 100 is, for example, a window of a moving body. It may be. Examples of moving objects may include automobiles, trains, aircraft, ships, construction machinery and amusement park vehicles. For example, when applied to a train window where the window cannot be opened and closed, the air volume of the air flow blown out from the nozzle portion 2 on the side in the traveling direction of the train is made larger than the air volume of the nozzle portion 2 on the opposite side to the outside. You can get a simulated experience as if the wind hits your face.

When the functional unit 5 has 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, dew condensation is likely to occur on one surface 101 on the front side (indoor side) of the window member 102 whose rear side is exposed to the outside air in a season such as winter. .. However, dew condensation can also be suppressed by the air flow from the left and right pair (or the upper and lower pair) of the nozzle portions 2. When suppressing dew condensation, an air stream containing cold air may be blown out so that the temperature difference between the outdoor and indoor areas is reduced.

The camera 280 may be provided separately from the display device 220, or a camera 280 provided in the housing 220a of the display device 220 may be used.

Here, the operating principle of the blower 210 will be described with reference to FIGS. 13A and 13B. First, the operating principle in which the airflow (fifth airflow 230FU) is sent out toward the front of the display surface 220b by the first outlet 215LU and the second outlet 215RU will be described.

From the first outlet 215LU, air is blown out substantially parallel to the display surface 220b in the first direction from the first position on the left side of the housing 220a to the second position on the right side. Then, the blown air is displayed by an attraction phenomenon due to the Coanda effect (a phenomenon in which a negative pressure region is generated between the blown air and the display surface 220b and the blown air is attracted to the negative pressure region side). A first airflow 230LU is formed along the surface 220b. Further, from the second outlet 215RU, air is blown out substantially parallel to the display surface 220b in the second direction from the second position on the right side of the housing 220a toward the first position on the left side. Then, the blown air forms a second airflow 230RU along the display surface 220b due to the attraction phenomenon due to the Coanda effect.

Here, the first outlet 215LU and the second outlet 215RU face each other. Therefore, the first airflow 230LU formed by the first outlet 215LU and the second airflow 230RU formed by the second outlet 215RU collide with each other in the upper front region 230CU of the display surface 220b. Then, the first airflow 230LU and the second airflow 230RU that collide with each other are sent out as a fifth airflow 230FU on the upper side of the display surface 220b by being pushed forward from the display surface 220b with the display surface 220b as a wall. Will be done.

The operating principle of sending the sixth airflow 230FL toward the front of the display surface 220b by the third outlet 215LL and the fourth outlet 215RL is the same as the operating principle of sending the fifth airflow 230FU. That is, the third airflow 230LL formed by the third outlet 215LL (see FIG. 12) and the fourth airflow 230RL formed by the fourth outlet 215RL collide with each other in the lower front region 230CL of the display surface 220b, and the display surface 220b Airflow is sent out in front of. As a result, the sixth airflow 230FL is sent forward from the display surface 220b on the lower side of the display surface 220b.

As described above, the blower 210 having the display device 220 of the second embodiment sends out the fifth airflow 230FU from the upper side of the display surface 220b toward the front by the first air outlet 215LU and the second air outlet 215RU. Further, the blower 210 having the display device 220 of the second embodiment sends out the sixth airflow 230FL from the lower side to the front side of the display surface 220b by the third air outlet 215LL and the fourth air outlet 215RL. Therefore, the blower 210 of the second embodiment can blow the airflow forward from two places on the display surface 220b. It should be noted that each airflow is blown out from the first outlet 215LU, the second outlet 215RU, the third outlet 215LL, and the fourth outlet 215RL so as to be substantially parallel to the display surface 220b. Is sufficient as long as the attraction phenomenon due to the Coanda effect can act. That is, the airflows blown from the first outlet 215LU, the second outlet 215RU, the third outlet 215LL, and the fourth outlet 215RL are slightly separated or approached from the direction parallel to the display surface 220b. However, it is included in the scope of "substantially parallel" in the present disclosure.

Next, with reference to FIGS. 14 to 16, airflows blown out from the first outlet 215LU, the second outlet 215RU, the third outlet 215LL, and the fourth outlet 215RL (first airflow 230LU, second airflow). A method of controlling the amount of air flow of 230RU, the third airflow 230LL, and the fourth airflow 230RL) will be described.

FIG. 14 is a block diagram showing a configuration of a blower device 210 for controlling the amount of airflow blown from the first outlet 215LU, the second outlet 215RU, the third outlet 215LL, and the fourth outlet 215RL. is there. FIG. 15 is a diagram schematically showing an example of controlling the amount of airflow blown from the first outlet 215LU, the second outlet 215RU, the third outlet 215LL, and the fourth outlet 215RL. FIG. 16 is a diagram schematically showing another example of controlling the amount of airflow blown from the first outlet 215LU, the second outlet 215RU, the third outlet 215LL, and the fourth outlet 215RL.

A control unit 270 is provided inside the blower 210. The control unit 270 includes a first airflow 230LU blown out from the first outlet 215LU, a second airflow 230RU blown out from the second outlet 215RU, and a third airflow 230LL blown out from the third outlet 215LL. It is an arithmetic unit that controls the amount of air blown to the fourth airflow 230RL blown out from the fourth air outlet 215RL. The control unit 270 controls the air flow amount of each of the first airflow 230LU, the second airflow 230RU, the third airflow 230LL, and the fourth airflow 230RL. Then, the control unit 270 causes the first airflow 230LU and the second airflow 230RU to collide with each other to generate a fifth airflow 230FU from the display surface 220b toward the front. Further, the control unit 270 causes the third airflow 230LL and the fourth airflow 230RL to collide with each other to generate the sixth airflow 230FL from the display surface 220b toward the front.

Here, the airflow amount of the first airflow 230LU blown out from the first airflow outlet 215LU is determined by the airflow amount of the first airflow machine 260LU that supplies air to the first airflow outlet 215LU. The airflow amount of the second airflow 230RU blown out from the second airflow outlet 215RU is determined by the airflow amount of the second airflow machine 260RU that supplies air to the second airflow outlet 215RU. The amount of airflow of the third airflow 230LL blown out from the third outlet 215LL is determined by the amount of airflow of the third airflow machine 260LL that supplies air to the third outlet 215LL. The airflow amount of the fourth airflow 230RL blown out from the fourth airflow outlet 215RL is determined by the airflow amount of the fourth airflow machine 260RL that supplies air to the fourth airflow outlet 215RL.

Therefore, the control unit 270 controls the amount of each of the first blower 260LU, the second blower 260RU, the third blower 260LL, and the fourth blower 260RL. As a result, the control unit 270 controls the amount of airflow blown from the first outlet 215LU, the second outlet 215RU, the third outlet 215LL, and the fourth outlet 215RL.

A camera 280 is connected to the control unit 270. Further, a storage unit 290 is connected to the control unit 270. The storage unit 290 is provided inside the blower 210, and stores the airflow transmission position and the air volume on the display surface 220b suitable for the image together with the image information displayed on the display device 220.

In the following, two methods for determining the amount of each of the first blower 260LU, the second blower 260RU, the third blower 260LL and the fourth blower 260RL will be described.

First, the first method will be explained. The control unit 270 has, for example, the first blower 260LU, the second blower 260RU, the third blower 260LL, and the fourth blower 260RL, respectively, based on the airflow transmission position and the air volume on the display surface 220b stored in the storage unit 290. Determine the amount of airflow.

For example, as shown in FIG. 15, the storage unit 290 stores the airflow from the upper front area 230CU set in the upper right of the display surface 220b and the lower front area 230CL set in the lower left so as to send the airflow forward. Suppose it was. In this case, the control unit 270 is set so that each airflow (first airflow 230LU and second airflow 230RU) is blown out from the first outlet 215LU with a strong airflow and from the second outlet 215RU with a weak airflow. The amount of air blown by the first blower 260LU and the second blower 260RU is controlled. Further, the control unit 270 is set to the third so that each airflow (third airflow 230LL and fourth airflow 230RL) is blown out from the third airflow outlet 215LL with a weak airflow and from the fourth airflow outlet 215RL with a strong airflow. The amount of air blown by the blower 260LL and the fourth blower 260RL is controlled. As a result, the blower 210 can send each airflow (fifth airflow 230FU and sixth airflow 230FL) forward from the upper right region and the lower left region of the display surface 220b.

Further, as shown in FIG. 16, the storage unit 290 sends a strong airflow forward from the upper front area 230CU set in the upper right of the display surface 220b and a weak airflow from the lower front area 230CL set in the lower left. It is assumed that it was remembered in. In this case, the control unit 270 controls the amount of air blown by the first blower 260LU and the second blower 260RU as follows. That is, each airflow (first airflow 230LU and second airflow 230LU and second) is generally stronger from the first outlet 215LU and the second outlet 215RU while weakening the airflow of the second outlet 215RU than the airflow from the first outlet 215LU. The control unit 270 controls so that the airflow 230RU) is blown out. Further, the control unit 270 controls the amount of air blown by the third blower 260LL and the fourth blower 260RL as follows. That is, while strengthening the air volume of the fourth air outlet 215RL than the air volume from the third air outlet 215LL, each air flow (third airflow 230LL, fourth airflow 230LL, fourth airflow) is generally weaker from the third airflow outlet 215LL and the fourth outlet 215RL. The control unit 270 controls so that the airflow 230RL) is blown out. As a result, the blower 210 can send a strong airflow (fifth airflow 230FU) from the upper right of the display surface 220b and a weak airflow (sixth airflow 230FL) from the lower left toward the front.

In this way, the control unit 270 determines the position at which the fifth airflow 230FU is generated on the display surface 220b and the sixth airflow 230FL on the display surface 220b based on the content of the image displayed on the display surface 220b of the display device 220. Control the position to generate. As a result, the blower 210 can send each airflow forward from the plurality of portions of the display surface 220b.

Next, the second method will be described.

Further, the blower 310 includes a fourth outlet 311R on the right side of the housing 320a at a position away from the display surface 320b from the second outlet 310R.

The third air outlet 311L blows out the third airflow 331L from the left side of the housing 320a in the direction away from the display surface 320b (forward in the third embodiment). The fourth air outlet 311R blows out the fourth airflow 331R from the right side of the housing 320a in a direction away from the display surface 320b (forward in the third embodiment).

As shown in FIG. 18, a first air conduction path 313L and a third air conduction path 314L are formed inside the left side of the housing 320a. A second air conduction path 313R and a fourth air conduction path 314R are formed inside the right side of the housing 320a.

The first air conduction path 313L communicates with the first outlet 310L, and the first blower 340L is connected to the port opposite to the first outlet 310L. By blowing air from the first blower 340L to the first air conduction path 313L, the blown air is blown out from the first air outlet 310L as the first airflow 330L through the first air conduction path 313L.

The third air conduction passage 314L communicates with the third air outlet 311L, and the third blower 341L is connected to the port opposite to the third air outlet 311L. By blowing air from the third blower 341L to the third air conduction path 314L, the blown air is blown out from the third air outlet 311L as the third airflow 331L through the third air conduction path 314L.

The fourth air conduction path 314R communicates with the fourth air outlet 311R, and the fourth blower 341R is connected to the port opposite to the fourth air outlet 311R. By blowing air from the fourth blower 341R to the fourth air conduction path 314R, the blown air is blown out from the fourth air outlet 311R as the fourth airflow 331R through the fourth air conduction path 314R.

Further, the blower 310 has a camera 380 provided above the housing 320a of the display device 320. The camera 380 is an example of the imaging device of the present disclosure, and is used to image a region in front of the display device 320 and identify the existence and location of a viewer who views the display device 320 from the captured image. .. The camera 380 may be provided separately from the display device 320, or a camera provided in the housing 320a of the display device 320 may be used.

Here, the operating principle of the blower 310 will be described with reference to FIG. From the first air outlet 310L, the first airflow 330L is blown out substantially parallel to the display surface 320b in the first direction from the left side to the right side of the housing 320a. Then, the blown out first airflow 330L is attracted by the Coanda effect (a negative pressure region is generated between the first airflow 330L and the display surface 320b, and the first airflow 330L is attracted to the negative pressure region side). ) Flows along the display surface 320b. Further, when the second airflow 330R is blown out from the second outlet 310R in the second direction from the right side to the left side of the housing 320a substantially parallel to the display surface 320b, the blown out second airflow 330R becomes the Coanda. It flows along the display surface 320b due to the effect attraction phenomenon.

Here, in the third embodiment, the first outlet 310L and the second outlet 310R face each other, and are formed by the first airflow 330L formed by the first outlet 310L and the second outlet 310R. The second airflow 330R collides with the front region of the display surface 320b. Then, the collision first airflow 330L and the second airflow 330R are sent out as the fifth airflow 330F by having the display surface 320b as a wall and being pushed forward from the display surface 320b.

On the other hand, the third airflow 331L blown out from the third outlet 311L and the fourth airflow 331R blown out from the fourth outlet 311R surround the fifth airflow 330F sent forward from the display surface 320b. It will be in a state of being. It can be said that this is a state in which the fifth airflow 330F is sent out in the region sandwiched between the third airflow 331L and the fourth airflow 331R. That is, the third airflow 331L and the fourth airflow 331R function as an air curtain, and it is possible to prevent the fifth airflow 330F from diffusing outside the third airflow 331L and the fourth airflow 331R. Therefore, the airflow blown out from the first outlet 310L and the second outlet 310R can efficiently send out the fifth airflow 330F from the display surface 320b toward the front.

Each airflow (first airflow 330L, second airflow 330R) is blown out from the first outlet 310L and the second outlet 310R so as to be substantially parallel to the display surface 320b. As long as the attraction phenomenon due to the Coanda effect can act. That is, even if the airflow blown out from the first outlet 310L and the second outlet 310R is slightly separated or approached from the direction parallel to the display surface 320b, it is within the range of "substantially parallel" of the present disclosure. included.

Next, with reference to FIG. 19, each airflow (first airflow 330L, second airflow 330R,) blown out from the first airflow outlet 310L, the second airflow outlet 310R, the third airflow outlet 311L, and the fourth airflow outlet 311R. A method of controlling the amount of airflow of the third airflow 331L and the fourth airflow 331R) will be described. FIG. 19 is a block diagram for controlling the amount of airflow blown from the first outlet 310L, the second outlet 310R, the third outlet 311L, and the fourth outlet 311R.

A control unit 370 is provided inside the blower 310. The control unit 370 has a first airflow 330L blown out from the first outlet 310L, a second airflow 330R blown out from the second outlet 310R, and a third airflow blown out from the third outlet 311L. It is an arithmetic unit that controls the amount of airflow of the airflow 331L and the amount of airflow of the fourth airflow 331R blown out from the fourth airflow outlet 311R.

Here, the air flow amount of the first airflow 330L blown out from the first air outlet 310L is determined by the air flow amount of the first air blower 340L that supplies air to the first air outlet 310L. The amount of air blown by the second airflow 330R blown out from the second air outlet 310R is determined by the amount of air blown by the second blower 340R that supplies air to the second air outlet 310R. The amount of airflow of the third airflow 331L blown out from the third outlet 311L is determined by the amount of airflow of the third blower 341L that supplies air to the third outlet 311L. The airflow amount of the fourth airflow 331R blown out from the fourth airflow outlet 311R is determined by the airflow amount of the fourth airflow machine 341R that supplies air to the fourth airflow outlet 311R.

Therefore, the control unit 370 controls the amount of air blown by each of the first blower 340L, the second blower 340R, the third blower 341L, and the fourth blower 341R. As a result, the control unit 370 controls the amount of airflow blown from the first outlet 310L, the second outlet 310R, the third outlet 311L, and the fourth outlet 311R.

A camera 380 is connected to the control unit 370. Further, a storage unit 390 is connected to the control unit 370. The storage unit 390 is provided inside the blower 310, and stores the airflow transmission position and the air volume on the display surface 320b suitable for the content of the image together with the image information displayed on the display device 320.

In the following, two methods for determining the amount of each of the first blower 340L, the second blower 340R, the third blower 341L and the fourth blower 341R will be described.

First, the first method will be explained. The control unit 370 has, for example, the first blower 340L and the second blower based on the airflow transmission position and the air volume on the display surface 320b, which is stored in the storage unit 390 and is suitable for the content of the image displayed on the display surface 320b. The airflow amount of each of the 340R, the third blower 341L and the fourth blower 341R is determined.

For example, it is assumed that the storage unit 390 is stored so as to send out the fifth air flow 330F from a predetermined position on the display surface 320b toward the front with a predetermined air volume. In this case, the control unit 370 of the first airflow 330L blown out from the first airflow outlet 310L so that the fifth airflow 330F is sent forward from the display surface 320b at a predetermined air volume from the predetermined position. The amount of air blown and the amount of airflow of the second airflow 330R blown out from the second air outlet 310R are calculated. Then, based on the calculated airflow amount of the first airflow 330L blown out from the first airflow outlet 310L and the airflow amount of the second airflow 330R blown out from the second airflow outlet 310R, the control unit 370 sets the first blower 340L. And control the air flow amount of the second blower 340R.

Further, the control unit 370 properly surrounds the fifth airflow 330F that is sent forward from the predetermined position, and the amount of airflow of the third airflow 331L and the third airflow 331L that are blown out from the third airflow outlet 311L. The amount of airflow of the fourth airflow 331R blown out from the four outlets 311R is calculated. Then, based on the calculated airflow amount of the third airflow 331L blown out from the third airflow outlet 311L and the airflow amount of the fourth airflow 331R blown out from the fourth airflow outlet 311R, the control unit 370 sets the third airflow machine 341L. And the air flow amount of the fourth blower 341R is controlled.

In this way, the control unit 370 controls the position on the display surface 320b where the fifth air flow 330F is generated, based on the content of the image displayed on the display surface 320b of the display device 320.

Next, the second method will be described. The control unit 370 grasps the position of the viewer in front of the display device 320 and the age, gender, etc. of the viewer from the image of the area in front of the display device 320 captured by the camera 380. Then, the control unit 370 sends the first blower 340L and the second blower 340R to the main viewer so as to send the fifth airflow 330F of the air volume suitable for the viewer from the display surface 320b. Determine the air volume. Here, the air volume suitable for the viewer is, for example, a relatively strong air volume when the viewer is far away, a young person (younger age), or a man, and the viewer has a relatively strong air volume. The air volume is relatively weak if you are nearby, if you are elderly or if you are a woman.

Further, the control unit 370 determines the amount of airflow of the third blower 341L and the fourth blower 341R, which are necessary to appropriately surround the fifth airflow 330F to be sent out. Then, the control unit 370 controls the first blower 340L, the second blower 340R, the third blower 341L, and the fourth blower 341R so as to obtain the determined air flow amount.

Then, the control unit 370 controls the position on the display surface 320b where the fifth air flow 330F is generated, based on the image captured by the camera 380.

As described above, the control unit 370 controls the amount of airflow of each airflow blown out from the first outlet 310L, the second outlet 310R, the third outlet 311L, and the fourth outlet 311R. Then, the control unit 370 causes the first airflow 330L and the second airflow 330R to collide with each other in the region sandwiched between the third airflow 331L and the fourth airflow 331R, so that the fifth airflow 330F is directed forward from the display surface 320b. Causes. Therefore, the blower 310 can send out the fifth airflow 330F from the predetermined position on the display surface 320b with a predetermined air flow, and the third airflow 331L and the fourth airflow 331R send out the fifth airflow forward from the display surface 320b. The five airflows 330F can be reliably surrounded. Therefore, the airflow blown out from the first outlet 310L and the second outlet 310R can efficiently send out the fifth airflow 330F from the display surface 320b toward the front.

Whether the control unit 370 determines the amount of air blown by the first blower 340L, the second blower 340R, the third blower 341L, and the fourth blower 341R by the above-mentioned first method or the second method is determined. It may be set by a switch (not shown) provided in the device 310. Further, this setting may be performed by storing the setting information for each image information stored in the storage unit 390. Further, the control unit 370 may be configured to determine these airflow amounts only based on the airflow delivery position on the display surface 320b stored in the storage unit 390. Further, the control unit 370 may be configured to determine the amount of air blown only based on the image of the area in front of the display device 320 captured by the camera 380.

As described above, according to the blower 310 according to the third embodiment, the first airflow 330L blown out from the first outlet 310L and the second airflow 330R blown out from the second outlet 310R move forward from the display surface 320b. The fifth airflow 330F is sent toward the direction. Further, the third airflow 331L blown out from the third outlet 311L and the fourth airflow 331R blown out from the fourth outlet 311R surrounded the fifth airflow 330F sent forward from the display surface 320b. It becomes a state. That is, in the region sandwiched between the third airflow 331L and the fourth airflow 331R, the fifth airflow 330F is sent forward from the display surface 320b. Therefore, it is possible to prevent the fifth airflow 330F from diffusing outside the third airflow 331L and the fourth airflow 331R. As a result, the blower 310 according to the third embodiment efficiently uses the airflow (first airflow 330L and second airflow 330R) blown out from the first outlet 310L and the second outlet 310R from the display surface 320b. The fifth airflow 330F can be sent forward.

Although the present disclosure has been described above based on the third embodiment, the present disclosure is not limited to the third embodiment, and various improvements and modifications can be made without departing from the spirit of the present disclosure. That is easy to guess. For example, the third embodiment can be obtained by adding a part or a plurality of parts of the configuration of another embodiment to the third embodiment or exchanging a part or a plurality of parts of the configuration of the third embodiment. It may be modified and configured. Further, the numerical values given in each of the above embodiments are examples, and it is naturally possible to adopt other numerical values.

In the blower 310 according to the third embodiment, the third outlet 311L is provided on the left side of the same housing 320a as the first outlet 310L, and the fourth outlet 311R is provided in the same housing 320a as the second outlet 310R. It was explained as being provided on the right side.

However, this is an example, and the third outlet 311L may be provided on the upper side of the housing 320a, and the fourth outlet 311R may be provided on the lower side of the housing 320a facing the upper side. Also by this, the third airflow 331L blown out from the third airflow outlet 311L and the fourth airflow 331R blown out from the fourth airflow outlet 311R can surround the fifth airflow 330F sent forward from the display surface 320b. it can. Therefore, it is possible to prevent the fifth airflow 330F from diffusing outside the third airflow 331L and the fourth airflow 331R. Therefore, the blower device according to this modification can efficiently send the fifth airflow 330F forward from the display surface 320b by the wind blown from the first outlet 310L and the second outlet 310R.
