Note that the embodiments described below are merely examples of the embodiments of the present disclosure. The present disclosure is not limited to the following embodiments, and various changes can be made depending on the design and the like as long as the effects of the present disclosure can be achieved.

Further, in the following description, unless otherwise specified, the X-axis, Y-axis, and Z-axis that are orthogonal to each other are defined in FIG. For convenience, one of the two directions along the X-axis is to the right and the other is to the left. Further, one of the two directions along the Y axis is the front direction, and the other direction is the rear direction. Further, one of the two directions along the Z axis is the upward direction, and the other direction is the downward direction.

(Embodiment)
(1) Outline of the ventilation system FIGS. 1 and 2 show the configuration of the ventilation system 1 of the present embodiment. The ventilation system 1 is used in a facility such as an office building, an office, a store, a factory, or a commercial facility. Further, the ventilation system 1 may be used in a dwelling unit of an apartment house, a detached house, or the like.

The ventilation system 1 is attached to the ceiling 91 of the air conditioning space 9. In this case, the ceiling 91 corresponds to the structure to which the ventilation system 1 is attached. The ventilation system 1 sucks the air in the air conditioning space 9 as the second air A2. Further, the ventilation system 1 is connected to an external ventilation passage 2 such as a duct arranged in the attic space 92 above the ceiling 91, and is sent out from an air conditioning facility (not shown) via the external ventilation passage 2. Receive the third air A3. Then, the ventilation system 1 blows out the air obtained by mixing the second air A2 and the third air A3 into the air conditioning space 9 as the first air A1.

Specifically, the blower system 1 includes a blower device 3, a chamber device 4, a duct 5, and a controller K1. The controller K1 drives the blower device 3 and the chamber device 4 to control each operation of the blower device 3 and the chamber device 4. The chamber device 4 produces the first air A1 by mixing the second air A2 and the third air A3. The blower device 3 and the chamber device 4 are connected to each other via a duct 5, and the chamber device 4 supplies the first air A1 to the blower device 3 by flowing the first air A1 into the duct 5. The blower 3 blows the first air A1 supplied from the duct 5 into the air conditioning space 9.

The third air A3 is harmonized air generated by air conditioning equipment, and is air in which at least one of temperature, humidity, and cleanliness is adjusted. That is, the blowing system 1 generates the first air A1 in which the second air A2 and the third air A3 are mixed, so that the first air A1 contains the harmonized air. The conditioned air may be air to which a scent is added or the amount of virus is reduced.

(2) Configuration of Blower The blower 3 includes a housing 31, a straightening vane 32, and a drive mechanism 33, as shown in FIGS. 2 to 5. The drive mechanism 33 is provided in the housing 31, and the straightening vane 32 is movably supported by the drive mechanism 33.

(2.1) Housing The housing 31 is formed in the shape of a hollow rectangular box mainly made of zinc steel plate, and has a left surface (side surface) 31a, a right surface (side surface) 31b, a front surface (side surface) 31c, and a rear surface (side surface). 31d, an upper end surface (first end surface) 31e, and a lower end surface (second end surface) 31f are provided. The housing 31 has an internal space 310 surrounded by a left surface 31a, a right surface 31b, a front surface 31c, a rear surface 31d, an upper end surface 31e, and a lower end surface 31f. The left surface 31a and the right surface 31b face each other in the left-right direction along the X axis. The front surface 31c and the rear surface 31d face each other in the front-rear direction along the Y axis. The upper end surface 31e and the lower end surface 31f face each other in the vertical direction along the Z axis.

A cylindrical air supply port 31g is provided in the center of the upper end surface 31e. The upper end of the air supply port 31g is connected to the duct 5, and the lower end of the air supply port 31g is spatially continuous with the internal space 310. The first air A1 sent out from the chamber device 4 to the duct 5 is blown from top to bottom into the internal space 310 of the housing 31 through the air supply port 31 g.

A rectangular opening is formed as a blower port 31h on the lower end surface 31f. The air outlet 31h is a rectangular plane along the XY plane (plane defined by the X-axis and the Y-axis), and the axial direction of the air outlet 31h is the direction along the Z-axis. A flange portion 31j constituting the throttle portion 31i is formed on the peripheral edge of the air outlet 31h. The throttle portion 31i expands the internal space 310 from the peripheral edge of the air outlet 31h to the outside of the air outlet 31h. Alternatively, the throttle portion 31i narrows the portion of the internal space 310 on the air outlet 31h side so as to narrow the internal space 310 toward the peripheral edge of the air outlet 31h. The flange portion 31j, which is an example of the throttle portion 31i, extends in a flange shape along the XY plane from the lower ends of the left surface 31a, the right surface 31b, the front surface 31c, and the rear surface 31d toward the air outlet 31h. That is, the lower end surface 31f is provided with a flange portion 31j extending from the peripheral edge of the air outlet 31h to the left surface 31a, the right surface 31b, the front surface 31c, and the rear surface 31d, with the throttle portion 31i.

In the present embodiment, it is preferable that the left surface 31a, the right surface 31b, the front surface 31c, the rear surface 31d, and the flange portion 31j of the housing 31 are made of one sheet metal-processed galvanized steel sheet. Further, the left surface 31a, the right surface 31b, the front surface 31c, the rear surface 31d, the upper end surface 31e, and the flange portion 31j of the housing 31 may be made of one sheet metal-processed zinc steel plate.

(2.2) Drive mechanism The drive mechanism 33 includes an electric actuator 33a and a support guide 33b.

The electric actuator 33a is attached to the front side of the upper end surface 31e of the housing 31. The electric actuator 33a includes an electric motor, a ball screw extending in the left-right direction along the X axis, a screw nut fitted in the ball screw, and a rod attached to the screw nut. The rotational force of the electric motor is transmitted to the ball screw, and the ball screw rotates with the axis of the ball screw as the rotation axis. The screw nut moves to the left along the X-axis when the ball screw rotates in one direction, and moves to the right along the X-axis when the ball screw rotates in the other. A rod is attached to the screw nut, and the rod also moves along the X axis according to the rotation of the ball screw like the screw nut.

The upper end surface 31e of the housing 31 is formed with an opening extending along the X axis facing the electric actuator 33a. The rod of the electric actuator 33a is connected to the upper ends of the first support and the second support, which are two rod-shaped supports. The lower ends of the first support and the second support are inserted into the internal space 310 through the opening of the upper end surface 31e and attached to the straightening vane 32. For example, in FIG. 6, an opening 31k is formed on the upper end surface 31e of the housing 31 along the X axis. The first support 33c is inserted through the opening 31k, the upper end of the first support 33c is connected to the rod of the electric actuator 33a, and the lower end of the first support 33c is attached to the straightening vane 32. The second support is also attached to the straightening vane 32 in the same manner as the first support 33c.

The support guide 33b is attached to the rear side of the upper end surface 31e of the housing 31. The support guide 33b includes a linear rail and a slider attached to the rail. The rail is attached so as to extend in the left-right direction along the X-axis. The slider moves linearly to the left and right along the rail. That is, the extending direction of the rail is the same as the displacement direction of the electric actuator 33a. The upper end surface 31e of the housing 31 is formed with an opening extending along the X axis facing the support guide 33b. The upper end of a third support, which is one rod-shaped support, is connected to the slider of the support guide 33b. The lower end of the third support is inserted into the internal space 310 through the opening of the upper end surface 31e and attached to the straightening vane 32. The third support is also attached to the straightening vane 32 in the same manner as the first support 33c (see FIG. 6).

The controller K1 controls the position of the electric actuator 33a. That is, the position of the rod of the electric actuator 33a is controlled by the controller K1.

(2.3) Straightening plate The straightening vane 32 is formed into a rectangular plate shape by resin molding using polypropylene as a material.

As shown in FIG. 5, the straightening vane 32 includes a first surface 32a and a second surface 32b facing in the thickness direction, the first surface 32a facing the upper end surface 31e, and the second surface 32b facing the lower end surface 31f. It is arranged in the internal space 310 so as to face each other. Two

circular insertion holes

32c and 32d are formed side by side in the left-right direction on the front side of the straightening vane 32. On the rear side of the straightening vane 32, one circular insertion hole 32e is formed in the middle in the left-right direction.

Then, the lower end of the first support of the electric actuator 33a abuts on the first surface 32a of the straightening vane 32 so as to face the insertion hole 32c. The lower end of the second support of the electric actuator 33a abuts on the first surface 32a of the straightening vane 32 so as to face the insertion hole 32d. Further, the lower end of the third support of the support guide 33b abuts on the first surface 32a of the straightening vane 32 so as to face the insertion hole 32e. Screw holes are formed along the Z axis at the lower ends of the first to third supports, and three screws 35 (see FIG. 4) are located below the straightening vanes 32 in the insertion holes 32c to 32e (the first). It is inserted from the side of the two surfaces 32b) and screwed into each screw hole of the first to third supports. As a result, the head 35a of the screw 35 is locked to the second surface 32b, and the straightening vane 32 is sandwiched between each head 35a of the three screws 35 and the lower ends of the first to third supports. , Is fixed to the first to third supports.

For example, in FIG. 6, the first support 33c has an opening 31k inserted, and the upper end of the first support 33c is connected to the rod of the electric actuator 33a. The lower end of the first support 33c is in contact with the first surface 32a of the straightening vane 32 so as to face the insertion hole 32c. Then, the screw 35 is inserted into the insertion hole 32c from below the straightening vane 32 (on the side of the second surface 32b) and screwed into the screw hole of the first support 33c. As a result, the straightening vane 32 is sandwiched between the head 35a of the screw 35 and the lower end of the first support 33c.

Further, the lower end of the second support abuts on the first surface 32a of the straightening vane 32 so as to face the insertion hole 32d, and the lower end of the third support of the straightening vane 32 faces the insertion hole 32e. The screw 35 abuts on the first surface 32a and is screwed into the screw holes of the second support and the third support (see FIG. 4).

Therefore, when the rod of the electric actuator 33a moves along the X axis, the straightening vane 32 also slides along the X axis. That is, the straightening vane 32 slides in the direction intersecting the Z axis along the axial direction of the air outlet 31h by the drive mechanism 33. The controller K1 controls the position of the straightening vane 32 by controlling the position of the electric actuator 33a. That is, assuming that the position of the straightening vane 32 along the X axis is the slide position, the sliding position of the straightening vane 32 is adjusted by the controller K1 controlling the position of the electric actuator 33a.

(2.4) Installation of the blower device As shown in FIG. 1, the blower device 3 is embedded and arranged in the mounting hole 91a of the ceiling 91. Each of the left side 31a and the right side 31b of the housing 31 is attached with two mounting brackets 34 arranged along the Y axis. Each of the front surface 31c and the rear surface 31d is attached with two mounting brackets 34 arranged along the X axis. Each of the mounting brackets 34 is formed in an L shape with a metal such as aluminum or stainless steel, and is fixed to the back surface (upper surface) of the ceiling 91 in the ceiling space 92 with screws.

FIG. 7 shows an outline of the installation structure of the blower device 3. In FIG. 7, the straightening vane 32, the drive mechanism 33, the mounting bracket 34, and the screw 35 of the blower device 3 are omitted. Since the housing 31 of the blower device 3 is embedded and arranged in the mounting hole 91a of the ceiling 91, the size of the mounting hole 91a is slightly larger than the size of the housing 31. As a result, a gap G1 is created between the outer periphery of the housing 31 embedded in the mounting hole 91a and the peripheral edge of the mounting hole 91a. Therefore, in order to hide the gap G1 generated in the ceiling 91, the frame body 36 is attached to the housing 31. The frame body 36 has a square frame shape and is attached to the lower end of the housing 31.

The frame body 36 includes a plate frame 36a formed in a square frame shape by a flat plate along an XY plane, and a mounting plate 36b extending upward from the upper surface of the plate frame 36a over the entire circumference of the plate frame 36a. The mounting plate 36b is inserted into the gap G1 from below and is attached to the lower end of the housing 31 by screws 37. The upper surface of the plate frame 36a abuts on the lower surface of the ceiling 91 and the lower surface of the flange portion 31j. As a result, the plate frame 36a covers the lower end of the gap G1 and can hide the gap G1 from below the ceiling 91. Further, the frame body is preferably a square frame body, and is formed to have an outer dimension of 600 mm × 600 mm, for example.

(3) Chamber device As shown in FIG. 2, the chamber device 4 includes a mounting member 41, a chamber box 42, an air supply cover 43, a ventilation device 44, and an air supply box 45.

The mounting member 41 is formed in the shape shown in FIG. 8 using an aluminum plate material. The mounting member 41 includes a substrate 41a, a first mounting base 41b, and a second mounting base 41c.

The substrate 41a has a rectangular plate shape in which the dimension in the front-rear direction along the Y axis is longer than the dimension in the left-right direction along the X axis. The first mounting base 41b is located on the front side of the board 41a, and the second mounting base 41c is located on the rear side of the board 41a.

The first mounting base 41b is formed in a rectangular box shape protruding upward on the upper surface of the substrate 41a. A rectangular opening 412 is formed on the upper surface of the first mounting base 41b, and a rectangular opening 411 facing the opening 412 is formed on the substrate 41a. A rectangular frame-shaped flange portion 413 along the outer periphery of the opening 412 is formed on the upper surface of the first mounting base 41b, and the ventilation device 44 shown in FIG. 9 is attached to the upper surface of the flange portion 413. Further, a rectangular box-shaped chamber box 42 having an open lower surface is attached to the first mounting base 41b so as to cover the ventilation device 44 (see FIG. 2).

The ventilation device 44 shown in FIG. 9 has a housing 44a containing a motor and a fan, an intake port 44b formed on the lower surface of the housing 44a, a rectangular plate-shaped louver 44c covering the intake port 44b, and a side surface of the housing 44a. The formed exhaust port 44d and the like are provided. Then, the ventilation device 44 sucks air from the intake port 44b covered with the louver 44c by rotating the fan by the motor in the housing 44a, and sucks the sucked air from the exhaust port 44d into the chamber box 42 (see FIG. 2). ).

The second mounting base 41c is formed in a rectangular box shape protruding upward on the upper surface of the substrate 41a. A rectangular opening 414 is formed on the upper surface of the second mounting base 41c. A rectangular frame-shaped flange portion 415 along the outer periphery of the opening 414 is formed on the upper surface of the second mounting base 41c, and the air supply box 45 shown in FIG. 10 is attached to the upper surface of the flange portion 415. Further, a rectangular box-shaped air supply cover 43 having an open lower surface is attached to the second mounting base 41c so as to cover the air supply box 45 (see FIG. 2).

The air supply box 45 shown in FIG. 10 has a rectangular plate-shaped dustproof structure that covers the housing 45a, the intake port 45b formed on the side surface of the housing 45a, the exhaust port 45c formed on the lower surface of the housing 45a, and the exhaust port 45c. A filter 45d and the like. The intake port 45b is connected to the external ventilation passage 2 (see FIGS. 1 and 2). Then, the air supply box 45 sucks the third air A3 sent out from the air conditioning equipment (not shown) through the external ventilation passage 2 from the intake port 45b, and the sucked third air A3 is an exhaust port covered with the dustproof filter 45d. It is discharged from 45c into the air supply cover 43 (see FIG. 2). The inside of the air supply cover 43 is connected to the inside of the chamber box 42 via a duct (not shown). Therefore, the third air A3 discharged from the exhaust port 45c of the air supply box 45 into the air supply cover 43 is sent out into the chamber box 42.

The above-mentioned chamber device 4 is embedded in the ceiling 91 so that the intake port 44b of the ventilation device 44 faces downward from the ceiling 91. Therefore, the ventilation device 44 sucks in the air in the air conditioning space 9 as the second air A2, and discharges the second air A2 into the chamber box 42.

The chamber box 42 is formed in a rectangular box shape mainly using a zinc steel plate, and the second air A2 is supplied from the ventilation device 44, and the third air A3 is supplied from the air supply box 45. The chamber box 42 produces the first air A1 by mixing the second air A2 and the third air A3. The inside of the chamber box 42 is connected to the air supply port 31 g of the blower device 3 via the duct 5. Then, the first air A1 generated in the chamber box 42 is sent out to the air supply port 31g of the blower device 3 through the duct 5, and is supplied from the air supply port 31g to the internal space 310 of the housing 31.

In the present embodiment, the ventilation device 44 and the air supply box 45 are attached to one attachment member 41. Therefore, since the ventilation device 44 and the air supply box 45 can be configured as one unit, it is easier to attach the ventilation device 44 and the air supply box 45 to the ceiling 91 than to configure them separately.

(4) Airflow control of the blower device As described above, the first air A1 is supplied from the chamber device 4 to the internal space 310 of the housing 31 of the blower device 3. Then, the drive mechanism 33 changes the slide position of the straightening vane 32 to control the directivity of the first air A1 blown out from the blower port 31h of the blower device 3 (airflow control).

Hereinafter, the airflow control of the blower device 3 will be described with reference to FIGS. 11A and 11B. In FIGS. 11A and 11B, the drive mechanism 33, the mounting bracket 34, and the screw 35 of the blower device 3 are omitted.

In FIG. 11A, the slide position of the straightening vane 32 is controlled in the center of the internal space 310. A gap forming the communication portion 311 is formed between the left end 32f of the straightening vane 32 and the left surface 31a of the housing 31. Further, a gap forming the communication portion 312 is formed between the right end 32g of the straightening vane 32 and the right surface 31b of the housing 31. The length dimensions of the communication portion 311 and the communication portion 312 along the X-axis are the same as each other. That is, gaps are formed on both the left and right sides of the straightening vane 32 to make the space on the first surface 32a side and the space on the second surface 32b side continuous. In this case, the first air A1 supplied from the top to the bottom to the internal space 310 from the air supply port 31g of the upper end surface 31e is the airflow F1 heading to the left along the first surface 32a of the straightening vane 32 and the right. It is divided into an airflow F2 heading in the direction. The air flow F1 passes through the communication portion 311 from top to bottom, and then travels to the right between the second surface 32b of the straightening vane 32 and the flange portion 31j. The air flow F2 passes through the communication portion 312 from top to bottom, and then travels to the left between the second surface 32b of the straightening vane 32 and the flange portion 31j. After the airflow F1 and the airflow F2 collide with each other, they are blown downward from the air outlet 31h. That is, the first air A1 is blown out directly below the air outlet 31h.

In FIG. 11B, the slide position of the straightening vane 32 is controlled so as to be offset to the right side of the internal space 310. A gap forming the communication portion 313 is formed between the left end 32f of the straightening vane 32 and the left surface 31a of the housing 31. Further, the right end 32g of the straightening vane 32 is in contact with the right surface 31b of the housing 31. That is, a gap is formed on the left side of the straightening vane 32 to connect the space on the first surface 32a side and the space on the second surface 32b side, but on the right side of the straightening vane 32, the first surface 32a side. There is no gap forming a continuous space between the space and the space on the second surface 32b side. In this case, the first air A1 supplied from the top to the bottom to the internal space 310 from the air supply port 31g of the upper end surface 31e becomes an air flow F3 heading to the left along the first surface 32a of the straightening vane 32. .. The air flow F3 passes through the communication portion 313 from top to bottom, and then travels to the right between the second surface 32b of the straightening vane 32 and the flange portion 31j. The airflow F3 is blown out from the air outlet 31h in the lower right diagonal direction. That is, the first air A1 is blown out from the air outlet 31h in the lower right diagonal direction.

Further, when the slide position of the straightening vane 32 is controlled to be offset to the left side of the internal space 310, the first air A1 is blown out from the air outlet 31h in the lower left diagonal direction.

As described above, the drive mechanism 33 includes the

communication portions

311 and 313, which are gaps formed between the left surface 31a of the housing 31 and the left end 32f of the straightening vane 32, and the right surface 31b of the housing 31 and the straightening vane 32. The straightening vane 32 is slid so as to change the communication portion 312, which is a gap formed between the right end 32g and the right end 32g. Then, the blower device 3 can control the directivity of the first air A1 blown out from the blower port 31h by changing the slide position of the straightening vane 32. Further, the blower device 3 can easily control the directivity of the first air A1 by adopting a simple configuration in which the straightening vane 32 is slid.

Further, the blower device 3 is provided with the flange portion 31j on the peripheral edge of the blower port 31h, so that the first air A1 blown out from the blower port 31h can be used as a directional airflow as compared with the case where the flange portion 31j is not provided. can. That is, the flange portion 31j has a function of increasing the directivity of the first air A1 blown out from the blower port 31h, and the blower device 3 can concentrate the first air A1 blown out from the blower port 31h in a narrow range. can. In other words, the first air A1 reaches only the targeted region and has low diffusivity to the surroundings.

Therefore, the blower 3 uses the first air A1 as a directional airflow and controls its directivity to concentrate on a narrow range where one person (or a small number of people) exists, and to concentrate on the temperature, humidity, and cleanliness. A first air A1 adjusted for at least one of aroma and viral load can be blown out. That is, when controlling the air conditioning zone in the air conditioning space 9, each zone can be narrowed and the air quality can be adjusted for each narrow zone. It is also possible to change the position of the zone in the air-conditioned space 9. As a result, even when a person moves in the air-conditioned space 9 or when a plurality of people exist in the air-conditioned space 9, a comfortable air-conditioned environment can be provided for each person.

FIG. 12A shows a simulation result of the wind speed distribution of the first air A1 blown out from the blower device 3 provided with the flange portion 31j. In FIG. 12A, the slide position of the straightening vane 32 is controlled in the center of the internal space 310, and the range where the wind speed of the first air A1 is relatively high is a relatively narrow range R1 near the center of the air outlet 31h. focusing. That is, the first air A1 blown out from the blower device 3 is a directional airflow concentrated in a relatively narrow range R1 directly below the center of the blower port 31h.

FIG. 12B shows, as a comparative example, a simulation result of the wind speed distribution of the first air A1 blown out from the blower device 3A not provided with the flange portion 31j. In FIG. 12B, the slide position of the straightening vane 32 is controlled in the center of the internal space 310, and the range where the wind speed of the first air A1 is relatively high extends to a relatively wide range R2 below the air outlet 31h. .. That is, the first air A1 blown out from the blower device 3A is a diffusive airflow extending over a relatively wide range R2 below the blower port 31h.

As described above, the controller K1 of the blower device 3 controls the position of the straightening vane 32 (position control of the electric actuator 33a). At this time, it is preferable that the controller K1 receives an external signal and controls the position of the straightening vane 32 based on the external signal. That is, the controller K1 adjusts the slide position of the straightening vane 32 to the center of the internal space 310 (see FIG. 11A), the right side of the internal space 310 (see FIG. 11B), or the left side of the internal space 310 according to the external signal. can do. The slide position of the straightening vane 32 may be continuously displaceable in four or more stages or steplessly, instead of the three stages of the center, right side, and left side of the internal space 310.

The external signal is, for example, a signal output by an operating device installed on the wall surface of the air conditioning space 9. The operation device includes at least one such as a push button, a slide knob, and a touch panel operated by a manager as an operation unit, and the operation unit is operated according to the slide position of the straightening vane 32. Then, the operating device outputs an external signal corresponding to the operation of the operating unit to the controller K1. In this case, the manager operates the operation unit according to the position of the person existing in the air-conditioned space 9. That is, the blower device 3 can generate a comfortable air-conditioned environment for each person in the air-conditioned space 9 by manually operating the operating device.

Further, the external signal may be, for example, a signal output by a human body detection sensor installed in the air-conditioned space 9. The human body detection sensor includes an infrared sensor, a camera image sensor, a thermal image sensor, and the like, detects the position of a person in the air-conditioning space 9, and outputs the detection result as an external signal to the controller K1. In this case, the controller K1 automatically controls the slide position of the straightening vane 32 according to the position of a person in the air conditioning space 9. That is, the blower device 3 can generate a comfortable air-conditioned environment for each person in the air-conditioned space 9 by automatic control using the human body detection sensor.

(5) Deformation Example of Straightening Plate The straightening vane 32 is preferably provided with three recesses on the second surface 32b, and insertion holes 32c to 32e are formed on the bottom surfaces of the three recesses, respectively. In this case, when the three screws 35 are inserted into the insertion holes 32c to 32e from below the straightening vane 32 (on the side of the second surface 32b) and screwed into the screw holes of the first to third supports, the inside of the recess is formed. The head 35a of the screw 35 is stored in the screw 35. Then, the opening of the recess is closed with a cover. As a result, the head 35a of the screw 35 is hidden by the cover, so that the design of the blower device 3 is improved.

For example, in FIG. 13, the second surface 32b of the straightening vane 32 is provided with a recess 32h, and a circular insertion hole 32i is formed on the bottom surface of the recess 32h. The lower end of the first support 33c connected to the rod of the electric actuator 33a is in contact with the bottom surface of the recess 32h so as to face the insertion hole 32c. Then, the screw 35 is inserted into the insertion hole 32c from below the straightening vane 32 (on the side of the second surface 32b) and screwed into the screw hole of the first support 33c. The head 35a of the screw 35 is housed in the recess 32h, and the opening of the recess 32h is closed by the cover 32j. Further, as in the case of the first support 33c, the screw 35 is screwed into the second support and the third support.

(6) Airflow control system FIG. 14 shows an airflow control system 8 using the above-mentioned blower system 1.

The airflow control system 8 includes a plurality of floor ventilation devices 71, air conditioning equipment 72, an external ventilation passage 2, and a return ventilation passage 21 in addition to the ventilation system 1.

Each of the plurality of floor ventilation devices 71 is embedded in the floor 93 of the air conditioning space 9 and sucks the air in the air conditioning space 9 as the fourth air A4. The fourth air A4 sucked by each of the plurality of floor ventilation devices 71 is supplied to the air conditioning equipment 72 through the return ventilation passage 21. By providing the plurality of floor ventilation devices 71, the air flow control system 8 can suck the fourth air A4 more strongly than in the case where the plurality of floor ventilation devices 71 are not provided. As a result, the airflow control system 8 can increase the ventilation volume per unit time in the air-conditioned space 9, and can quickly replace the air in the air-conditioned space 9.

The air conditioning equipment 72 adjusts at least one of the temperature, humidity, and cleanliness of the fourth air A4 and sends it out to the external ventilation passage 2 as the third air A3. The third air A3 is harmonized air generated by the air conditioning equipment 72. The conditioned air may be air to which a scent is added or the amount of virus is reduced.

The ventilation system 1 sucks the air in the air conditioning space 9 as the second air A2. Further, the ventilation system 1 receives the third air A3 sent out from the air conditioning equipment 72 through the external ventilation passage 2. Then, the ventilation system 1 blows out the air obtained by mixing the second air A2 and the third air A3 into the air conditioning space 9 as the first air A1.

The ventilation system 1 uses the first air A1 as a directional airflow and controls its directivity to concentrate on a narrow range where one person (or a small number of people) exists, and to concentrate on the temperature, humidity, cleanliness, and scent. , The first air A1 adjusted to at least one viral load can be blown out. That is, when controlling the air conditioning zone in the air conditioning space 9, each zone can be narrowed and the air quality can be adjusted for each narrow zone. It is also possible to change the position of the zone in the air-conditioned space 9. As a result, the airflow control system 8 can provide a comfortable air-conditioned environment for each person H1 and H2 to each person H1 and H2 in the air-conditioned space 9.

Here, in FIG. 14, the direction of the first air A1 sent by the ventilation system 1 to the person H2 on the right side corresponds to the first state (see FIG. 11A) in which the straightening vane 32 is located substantially in the center in the left-right direction. do. Further, in FIG. 14, the direction of the first air A1 sent by the ventilation system 1 to the person H1 on the left side is such that the straightening vane 32 is not substantially in the center of the left-right direction but on either side of the left-right direction (right side in FIG. 11B). Corresponds to the second state (see FIG. 11B). The switching control between the first state and the second state of the rectifying plate 32 is manually controlled by the operating device installed on the wall surface of the air conditioning space 9, and the human body detection sensor (infrared sensor,) installed in the air conditioning space 9. It may be either an automatic control using a camera image sensor, a thermal image sensor, or the like). The human body detection sensor detects the positions of people H1 and H2 with respect to the ventilation system 1 (directly below the ventilation system 1, right side, left side, etc.).

Further, for the automatic control of the straightening vane 32, an authentication system (not shown) that performs an authentication process when entering the air-conditioned space 9 may be used. The authentication system uses, for example, a card reader or a biometric authentication device to determine whether or not a person can enter the air-conditioned space 9, and manages entry and exit of the air-conditioned space 9. The ventilation system 1 automatically controls the straightening vane 32 using the authentication result of the authentication system. For example, the persons H1 and H2 who are permitted to enter the air-conditioned space 9 by the authentication system, the positions of the seats of the persons H1 and H2, and the ventilation system 1 in the vicinity of each seat are paired and associated with each other. Then, the ventilation system 1 controls the position of the straightening vane 32 of each ventilation system 1 so that the first air A1 faces each of the seats of the people H1 and H2.

At this time, the ventilation system 1 holds in advance the data of the favorite air qualities of the people H1 and H2, and the first air blown out by each of the blasting systems 1 to blow out the favorite air qualities of the people H1 and H2. It is preferable to reflect it in A1. That is, the ventilation system 1 individually controls the quality of the first air A1 blown out by each ventilation system 1 so that the air quality is the preference of each individual of the person H1 and H2. For example, the person H1 prefers warm air rather than cold air because of its cold sensitivity, and also desires relaxation with a favorite scent. Therefore, the blowing system 1 in the vicinity of the person H1 blows warm air containing the favorite scent of the person H1 as the first air A1. Further, the person H2 has no request for air quality if the temperature in the air-conditioned space 9 is, for example, 25 degrees or less as in winter. However, since the human H2 is hot, if the temperature in the air-conditioned space 9 exceeds, for example, 25 degrees as in summer, cold air having a temperature of 24 degrees or less and dry air are desired. Therefore, if the air temperature in the air-conditioned space 9 exceeds 25 degrees, the ventilation system 1 in the vicinity of the person H2 blows cold air of 24 degrees or less, which is preferred by the person H2, and dry air as the first air A1. Such control of air quality is realized by executing a program created in advance by the computer of the ventilation system 1.

Further, if there is only one air-conditioning system 1 in the air-conditioned space 9, one air-conditioning system 1 controls the first air A1 for two people H1 and H2 as follows. When the first air A1 is blown to two people H1 and H2, the blowing system 1 alternately directs the blowing direction of the first air A1 to the person H1 for a predetermined time, and then turns the first air A1 toward the person H1 for a predetermined time. Similarly, the direction switching control is performed so that the air is directed to the person H1 for a predetermined time and the person H1 is directed to the person H1 for a predetermined time. At this time, as described above, as individual control for reflecting the individual preference of each of the person H1 and H2 in the first air A1, the air quality of each of the person H1 and H2 is set to the first air A1. It may be reflected alternately in.

Further, even if one blowing system 1 fixes the blowing direction of the first air A1 to two people H1 and H2 without performing the direction switching control for switching the blowing direction of the first air A1. good. In this case, the ventilation system 1 may reflect only the preferred air quality common to the two persons H1 and H2 in the first air A1. Alternatively, if there is no preferred air quality common to the two persons H1 and H2, a predetermined standard air quality may be reflected in the first air A1.

In the louver main body 441, a plurality of linear openings 442 extending in the left-right direction along the X axis are formed side by side in the front-rear direction along the Y axis. Further, the frame body 36 is arranged along the outer periphery of the housing 31, and hides the gap between the housing 31 and the ceiling 91 when viewed from below the ceiling 91.

FIG. 15B is a view of the ventilation system 1 using the louver 44e instead of the louver 44c as viewed from below. The louver 44e includes a rectangular plate-shaped louver body 443 that is long in the front-rear direction. On the rear side of the louver main body 443, a plurality of linear openings 444 extending in the left-right direction along the X axis are formed side by side in the front-rear direction along the Y axis. On the front side of the louver main body 443, a plurality of linear grooves 445 extending in the left-right direction along the X axis are formed side by side in the front-rear direction along the Y axis. The opening 444 is inserted in the vertical direction, and the groove 445 is closed in the vertical direction. That is, the louver 44e not only functions as a flow path of the second air A2 like the louver 44c, but can also improve the design when viewed from below.

It suffices to have a configuration in which the portion of the space 310 on the air outlet 31h side is narrowed down). For example, the throttle portion 31i may have a shape that gradually expands as the internal space 310 advances upward from the peripheral edge of the air outlet 31h.

Further, although the straightening vane 32 is a single plate member, a plurality of plate members may be used as the straightening vane instead of the straightening vane 32.

Further, the slide direction of the straightening vane 32 is not limited to the left-right direction along the X axis. That is, the slide direction of the straightening vane 32 may be a direction along a virtual line segment on the XY plane, for example, a front-back direction along the Y axis.

Further, the slide direction of the straightening vane 32 is not limited to the direction orthogonal to the Z axis, and may be any direction that intersects the Z axis.
