Description

TECHNICAL FIELD

[0001] The present disclosure relates to a blow-out unit configured to a blow-out port of a ventilation passage toward an indoor, and blow out air supplied through the ventilation passage toward the indoor. BACKGROUND

[0002] Patent Literature 1 (Japanese Patent Application Publication No. 2007-155309) discloses a wind direction adjusting baffle provided to an air blow-out port of an air conditioner. The wind direction adjusting baffle of Patent Literature 1 is provided to be adjustable in angle with respect to a rotation shaft, and the blow-out direction of air is adjusted by controlling a wind direction adjusting motor linked to the wind direction adjusting baffle. SUMMARY

[0003] PROBLEMS TO BE SOLVED BY THE INVENTION

[0004] In Patent Literature 1, the rotation shaft of the wind direction adjusting baffle is disposed in the center portion of the wind direction adjusting baffle in a cross section in a direction perpendicular to the direction of the rotation shaft. In such a structure, if the wind direction adjusting baffle is rotated, air is blown out from both end sides of the wind direction adjusting baffle at the above-described cross section, and it is difficult to perform high-precision wind direction adjustment.

[0005] An object of the present disclosure is to provide a blow-out port having a simple structure and high freedom in wind direction adjustment.

The blow-out unit includes a first member and a second member disposed to the blow-out port. The first member is a plate member. The plate member moves a first edge of the plate member from the blow-out port into the ventilation passage by rotating around a rotation shaft apart from the first edge. The second member is disposed to a position different from the plate member at the blow-out port, and extends along the first edge of the plate member. The plate member and the second member change a first wind direction of air from the ventilation passage toward the blow-out port to a second wind direction, and the second wind direction is changed by the rotation of the plate member.

[0008] The blow-out unit of the first aspect can change the direction of air blown out from the blow-out port with a simple structure.

[0009] The blow-out unit of the second aspect is based on the blow-out unit of the first aspect, and in the blow-out unit of the second aspect, the second member is a guide portion. The guide portion has a first surface inclined toward the first edge from inside the ventilation passage. The plate member and the first surface of the guide portion change the first wind direction of air from the ventilation passage toward the blow-out port to the second wind direction.

[0010] The blow-out unit of the second aspect is capable of changing the direction of air blown from the blow-out port by rotating the plate member in a state where the first face of the guide portion is fixed.

[0058] <First Embodiment>

[0059] (1) Structure of Blow-out Unit 1

[0060] The blow-out unit 1 is disposed at the blow-out port P of the ventilation passage S toward the room, and blows air supplied through the ventilation passage S toward the room 3. Here, the supplied air includes air supplied as it is from outside air or room air, or air obtained by heating, cooling, dehumidifying, or humidifying outside air or room air. The blow-out port P is disposed at a ceiling surface or a wall surface of the room. The blow-out unit 1 is disposed at the ceiling back surface or the side wall back surface on the side of the ventilation passage S from the blow-out port P.

[0061] The blow-out unit 1 will be described with reference to the drawings. Figure 1 is a perspective view of the blow-out unit 1 as viewed from below the ceiling. Figure 2A 、 2B is a vertical sectional view of the blow-out unit 1 disposed at the ceiling back surface. Figure 3A 、 3B are diagrams each showing a result of simulation of air flow of the blow-out unit 1. Figure 2A 、 2B are diagrams each showing a result of simulation of air flow of the blow-out unit 1. Figure 4 is a diagram showing a range of rotation angle of the plate member 10 of the blow-out unit 1. Figure 5 is a control block diagram of the blow-out unit 1.

[0062] The blow-out unit 1 includes the plate member 10, the guide portion 200, the chamber case 30, the panel 33, the control portion 40, and the motor 41. The chamber case 30 is of a box shape, and has a suction port connected to a duct and a blow-out port through which air is blown. The structure of the chamber case 30 will be described later. The blow-out unit 1 is disposed at the ceiling back surface in such a manner that the blow-out port of the chamber case 30 is located at an opening portion of the ceiling surface 2 of the room. The chamber case 30 constitutes a part of the ventilation passage S, and the blow-out port of the chamber case 30 constitutes the blow-out port P of the ventilation passage S. The plate member 10 and the guide portion 200 are disposed at the blow-out port P. In the present embodiment, the blow-out port P is rectangular as viewed from the room side. The panel 33 is disposed at the ceiling surface in such a manner as to cover the periphery of the blow-out port P of the ceiling surface as viewed from the room side. The blow-out unit 1 blows air supplied through the chamber case 30 toward the room 3 by rotation of the plate member 10.

[0063] The plate member 10 is a rectangular plate having a prescribed thickness, and is disposed so that its surface is parallel to the ceiling surface. The surface of the plate member 10 on the room side is set as a first surface 101, and the surface on the side of the ventilation passage S is set as a second surface 102. The plate member 10 has a first edge 11a extending in a long direction and facing the guide portion 200, and a second edge 12a extending in parallel to the first edge 11a and facing the first wall surface 31 of the chamber case 30. The length of the plate member 10 in the long direction is substantially the same as the length of the blow-out port P in the long direction.

[0064] The shape of the plate member 10 can be appropriately changed according to the shape of the nozzle P. The plate member 10 may also be square instead of rectangular. The corners of the plate member 10 may be chamfered. The thickness D of the plate member 10 may be non-uniform. The thickness of the plate member 10 may decrease from the center of the plate member 10 towards the four ends.

[0065] In plate member 10, such as Figure 4 In the state shown, with the nozzle P in place, in a cross section (hereinafter referred to as section X) perpendicular to the nozzle P and extending from the plate member 10 along the guide portion 200, the end of the plate member 10 near the guide portion 200 is designated as the first end 11, and the end near the first wall surface 31 of the chamber box 30 is designated as the second end 12. The first end 11 is located at the first side 11a of the plate member 10, and the second end 12 is located at the second side 12a of the plate member 10. The plate member 10 has a pivot 15 on the second end 12 side. The distance between the pivot 15 and the second end 12 is less than 1 / 3 of the distance (length L) between the first end 11 and the second end 12 of the plate member 10. More preferably, the distance between the pivot 15 and the second end 12 is less than 1 / 2 of the thickness D of the plate member 10. As a result, when the plate member 10 is rotated, the amount of air flowing between the plate member 10 and the first wall surface 31 of the chamber box 30 can be reduced. Furthermore, even when the plate member 10 is rotated, it is possible to prevent the second end 12 from protruding towards the indoor side compared to the outlet P. For example... Figure 4 As shown, the plate member 10 can rotate 90° about the pivot 15 in the direction of the ventilation duct S. The plate member 10 can also rotate about the pivot 15 in the direction of the ventilation duct S by an angle from 0° to more than 45° but less than 90°. As long as it can rotate within the range that allows for adjustment of the airflow direction, it is acceptable.

[0066] A guide portion 200 is disposed opposite to the plate member 10 at the outlet P. The guide portion 200 is disposed adjacent to the first end 11 of the plate member 10 at section X. The guide portion 200 has a first surface 210, a second surface 220, a third surface 23, and a fourth surface 24 at section X, wherein the first surface 210 faces the ventilation duct S, the second surface 220 faces the interior, the third surface 23 faces the second wall surface 32 of the chamber 30, and the fourth surface 24 faces the first end 11 of the plate member 10. Specifically, the first surface 210 extends from the first end adjacent to the first end 11 of the plate member 10 to the second end. The second end is located on the opposite side of the first end from the interior side of the ventilation duct S and on the opposite side of the first end from the first end of the plate member 10 from the interior side. In other words, the first surface 210 is inclined from the second wall surface 32 side toward the plate member 10 side and from the ventilation duct S side toward the interior side. Figure 4In the sectional view, it is inclined in a straight line (planar) manner; however, it can also be inclined in a curved manner (curved surface). The second surface 220 is arranged parallel to the ceiling surface 2. When the plate member 10 is arranged in the state of the air outlet P, the first surface 101 of the plate member 10 on the interior side and the second surface 220 are arranged on the same plane. The second surface 220 is rectangular when viewed from the interior side. The second surface 220 has a first side 221 and a second side 222, wherein the first side 221 extends in the long side direction and extends parallel to the first side 11a of the plate member 10, and the second side 222 extends parallel to the first side 221 and faces the second wall surface 32 of the chamber box 30. The length of the second surface 220 in the long side direction can also be approximately the same as the length of the air outlet P in the long side direction. The third surface 23 contacts the second wall surface 32 in such a way that air does not flow between the third surface 23 and the second wall surface 32 of the chamber box 30. The fourth surface 24 is sandwiched between the first surface 210 and the second surface 220 and is parallel to the third surface 23.

[0067] The shape of the second surface 220 of the guide section 200 can be appropriately changed according to the shape of the nozzle P. The second surface 220 may also be a square instead of a rectangle. The corners of the second surface 220 may also be chamfered.

[0068] Figure 4 In the case where the plate member 10 is positioned at the outlet P, the second surface 220 of the guide portion 200 is arranged parallel to the first surface 101 of the plate member 10 facing the interior on the same horizontal plane. However, it is also possible that either the plate member 10 or the second surface 220 of the guide portion 200 is positioned on the ventilation duct S side.

[0069] like Figure 4 As shown, the plate member 10 can rotate 90° from its position at the outlet P until the first wall surface 31 is parallel to the second surface 102. Depending on the rotation angle of the plate member 10, the airflow direction and volume will change. Figure 4 The plate member 10 is shown in solid line, in other words, when the plate member 10 is located at the blow outlet P, the blow outlet P is closed by the plate member 10 and the guide portion 200.

[0070] The chamber case 30 is a box shape having a suction port connected to a duct and a blow-out port that blows out air. The suction port can be connected to an air handling unit such as an air exchange device, an air conditioning device, or the like through a duct. The blow-out port is substantially the same shape as the opening portion of the ceiling surface. The chamber case 30 has four wall surfaces that extend perpendicularly with respect to the blow-out port P. The blow-out port P is formed by the end portions of the four wall surfaces. The four wall surfaces include a first wall surface 31 on the side of the panel member 10 at the section X and a second wall surface 32 on the side of the guide portion 200. The suction port of the chamber case 30 can also be formed in the upper portion of the chamber case 30 or in the wall surface. The panel member 10 and the guide portion 200 are disposed at the blow-out port.

[0071] The blow-out unit 1 also includes a face plate 33. The face plate 33 is disposed on the ceiling surface 2 from the indoor side in a manner that covers the periphery of the blow-out port P of the ceiling surface 2. The face plate 33 is a frame having a prescribed thickness that extends from the ceiling surface 2 to a portion of the inner side of the blow-out port P. The face plate 33 covers a portion of the second end portion 12 side of the panel member 10 from the ceiling surface 2 at the section X and covers a portion of the second surface 220 of the guide portion 200 from the ceiling surface 2. The face of the face plate 33 on the indoor side is positioned more on the indoor side than the first surface 101 of the panel member 10 and the second surface 220 of the guide portion 200. In addition, the face of the face plate 33 on the indoor side can also be disposed in parallel with the first surface 101 of the panel member 10 and the second surface 220 of the guide portion 200 on the same plane. The face plate 33 can cover only the ceiling surface 2, but by extending to a portion of the inner side of the blow-out port P, it is possible to suppress the blow-out of air from between the second end portion 12 of the panel member 10 and the first wall surface 31 of the chamber case 30.

[0072] The motor 41 rotates the panel member 10 about the rotation shaft 15. The motor 41 can be a stepping motor. The motor 41 can be disposed inside the chamber case 30 or outside.

[0073] The control portion 40 controls the motor 41. The control portion 40 is a computer. The control portion 40 includes a processor and a storage portion. The control portion 40 can also be a microcomputer. The location where the control portion 40 is disposed is not particularly limited. The control portion 40 can also control a plurality of blow-out units 1 at the same time.

[0074] The control portion 40 can be controlled by the instruction of a remote controller operated by a user.

[0075] (2) Wind direction adjustment

[0076] In the blowing unit 1, the first surface 210 of the plate member 10 and the guide portion 200 changes the first airflow direction from the ventilation duct S toward the outlet P to a second airflow direction. When the plate member 10 is positioned at the outlet P, the outlet P is closed by the plate member 10 and the guide portion 200. Rotation of the plate member 10 moves the first end 11 of the plate member 10 from the outlet P to the ventilation duct S, opening the outlet P and allowing airflow. The air in the ventilation duct S flows between the first surface 101 of the plate member 10 and the first surface 210 of the guide portion 200 and is blown out from the outlet P into the room 3. Within the ventilation duct S, the airflow is directed towards a first airflow direction F1 parallel to either the first wall surface 31 or the second wall surface 32. The airflow direction changes to a second airflow direction F21 or F22 between the first surface 101 of the plate member 10 and the first surface 210 of the guide portion 200. The direction of the second airflow depends on the tilt angle of the first surface 210 of the guide portion 200 and the rotation angle of the plate member 10. The tilt angle of the first surface 210 of the guide section 200 is pre-designed and fixed to each blowing unit 1. The tilt angle of the first surface 210 of the guide section 200 is preferably 20° to 65° relative to the first wind direction. Alternatively, the tilt angle of the first surface 210 can be 25° to 70° relative to the horizontal, and more preferably 40° to 55°. The rotation angle of the plate member 10 is changed by rotating the plate member 10 using a motor 41.

[0077] The second wind direction changes according to the rotation angle of the plate member 10. To investigate how the wind direction of the air blown from the outlet P into the room 3 changes when the rotation angle of the plate member 10 of the blowing unit 1 changes, a simulation was conducted. As simulation conditions, the entire system was set to an isothermal field, and the blowing air volume was set to 10 m³ / s. 3 / points. In Figure 2A , 2B The simulation was conducted under the condition of the rotation angle of the plate member 10 of the blow-out unit 1 shown. Figure 3A , 3B The simulation results are shown separately.

[0078] exist Figure 2A , 3A In 2B and 3B, the inclination angle of the first surface 210 of the guide portion 200 is 35° to the horizontal. For example... Figure 2A , 3A As shown, when the rotation angle of the plate member 10 is 45° with the horizontal, the second wind direction F21 is 40° with the horizontal. Similarly, as... Figure 2B , 3B As shown, when the rotation angle of the plate member 10 is 80° with the horizontal, the second wind direction F22 is 70° with the horizontal. According to the simulation results, in the blowing unit 1, the larger the rotation angle of the plate member 10 with the horizontal, the smaller the angle change of the first wind direction F1 (vertical direction) towards the second wind directions F21 and F22.

[0079] (3) Shape parameter of blowing unit 1

[0080] The shape parameter of the blowing unit 1 will be described. Figure 4 is a view in which the shape parameter is described at the vertical cross-sectional view (cross section X) of the blowing unit 1.

[0081] With respect to the length L between the first end portion 11 and the second end portion 12 of the plate member 10, the following condition is preferably satisfied. With respect to the length W of the blowing port P in the direction from the first end portion 11 toward the second end portion 12 (the width of the air duct, Figure 4 is the interval between the first wall surface 31 and the second wall surface 32), the condition of formula (1) is preferably satisfied.

[0082] W / 4 < L < W / 2 (1)

[0083] In other words, the length L of the plate member 10 is preferably smaller than the length W-L at the blowing port P of the guide portion 200.

[0084] Further, with respect to the thickness D of the plate member 10, the condition of formula (2) is preferably satisfied.

[0085] 0 < D < W / 8 (2)

[0086] In other words, by setting the thickness D of the plate member 10 to a certain range, the control of the wind direction becomes smoother.

[0087] Next, the length H1 of the fourth face 24 of the guide portion 200 preferably satisfies formula (3).

[0088] 0 < H1 < W / 8 (3)

[0089] In other words, by setting the length H1 of the fourth face 24 to a certain range, the control of the wind direction becomes smoother.

[0090] Further, the distance (bevel height H2) of the first face 210 of the guide portion 200 along the first wind direction F1 satisfies formula (4).

[0091] 0 < H2 < W (4)

[0092] In other words, by setting the inclination angle of the first face of the guide portion 200 to a certain range, the control of the wind direction becomes smoother.

[0093] (4) Features

[0094] (4-1)

[0095] In this embodiment, the blowing unit 1 is disposed at the outlet P of the ventilation duct S facing the room 3, and blows air supplied through the ventilation duct S into the room 3. The blowing unit 1 has a plate member 10 and a guide portion 200. The plate member 10 rotates about a pivot 15 and moves from a state disposed at the outlet P to a state inside the ventilation duct S. The guide portion 200 has a first surface 210 facing the ventilation duct S. The first surface 210 is inclined from the second wall surface 32 side toward the first wall surface 31 side and from the ventilation duct S side toward the room side. The blowing unit 1 changes the first airflow direction F1 of the air from the ventilation duct S toward the outlet P to a second airflow direction F21, F22 according to the rotation angle of the plate member 10 and the inclination angle of the first surface 210 of the guide portion 200. Furthermore, the blowing unit 1 changes the second airflow direction blown out from the outlet P by changing the rotation angle of the plate member 10.

[0096] With this structure, the blowing unit 1 of this embodiment can easily control the airflow direction with a simple structure.

[0097] (4-2)

[0098] Plate component 10 is approximately rectangular in shape, such as... Figure 4 As shown, the plate member 10 has a first end portion 11 (first side 11a) on the guide portion 200 side and a second end portion 12 on the first wall surface 31 side when positioned at the blow outlet P, as well as a pivot 15. The pivot 15 is closer to the second end portion 12 than the first end portion 11. The distance between the pivot 15 and the second end portion 12 is less than 1 / 3 of the length L of the plate member (the distance between the first end portion 11 and the second end portion 12). In other words, the pivot 15 passes through 1 / 3 of the length L of the plate member 10 from the second end portion 12 and is positioned between the first wall surface 31 and a straight line orthogonal to the blow outlet P.

[0099] An air-blowing portion of the outlet P is formed at one location between the plate member 10 and the guide portion 200. No air-blowing portion is formed between the first wall surface 31 and the plate member 10, or between the guide portion 200 and the second wall surface 32.

[0100] The blown air is blown into the room 3 through the space between the first surface 101 of the plate member 10 and the first surface 210 of the guide part 200.

[0101] With this structure, the blowing unit 1 of this embodiment can easily control the airflow direction with a simple structure.

[0102] (4-3)

[0103] The first surface 210 of the guide section 200 is tilted in such a way that it allows air to collide with the first wind direction F1, which is parallel to the first wall surface 31 and the second wall surface 32 of the ventilation duct S. The tilt angle of the first surface 210 is more than 20° and less than 65° relative to the first wind direction F1.

[0104] As the rotation angle of the plate member 10 from the blowout port P (horizontal) side toward the duct S side becomes larger, the magnitude of the angle change from the first direction Fl toward the second direction becomes smaller.

[0105] (4-4)

[0106] The length L of the plate member 10 of the present embodiment satisfies the relationship of W / 4 < L < W / 2 with respect to the length W (width of the duct) of the blowout port P in the direction from the first end portion 11 toward the second end portion 12. The length L of the plate member 10 is smaller than the length W-L of the guide portion 200.

[0107] (4-5)

[0108] The blowout unit 1 further includes a chamber box 30 that constitutes a part of the duct S. The chamber box 30 is disposed on the back surface of the ceiling or the back surface of the side wall. The chamber box 30 has a first wall surface 31 on the plate member 10 side and a second wall surface 32 on the guide portion 200 side. The chamber box 30 is formed with an opening portion that constitutes the blowout port P. The plate member 10 and the guide portion 200 are disposed on the opening portion.

[0109] (5) Modification

[0110] (5-1) Modification 1A

[0111] In the blowout unit 1 of the first embodiment, the rotation shaft 15 of the plate member 10 can also be located outside the plate member 10. The rotation shaft 15 can also not be located between the extension plane of the first face 101 and the extension plane of the second face 102 of the plate member 10.

[0112] As Figure 6 shown, the structure of the blowout unit la of Modification 1A is the same as that of the blowout unit 1 of the first embodiment except that the rotation shaft 15a is located on the plate member 10p and the first face 210 and the second face 220 of the guide portion 200p are in contact.

[0113] In the blowout unit la of Modification 1A, in a cross-sectional view of Figure 6 , the plate member 10p has the first end portion 11 of the first side and the second end portion 12 of the first wall surface 31 facing the duct S. A rotation metal piece is fixed to the plate member 10p and the first wall surface 31, and the plate member 10p rotates around the rotation shaft 15a of the rotation metal piece. The rotation shaft 15a of the rotation metal piece can be rotated by the action of a motor or in a manual manner.

[0114] (5-2) Modification 1B

[0115] Except for the absence of a motor and control unit, the blowing unit of Modified Example 1B is structurally identical to the blowing unit 1 of the first embodiment. In the blowing unit 1 of Modified Example 1B, the rotation angle of the plate member 10 is always used in the same state. When the rotation angle needs to be changed, it is changed manually.

[0116] The blowing unit of Modified Example 1B is used when it is not necessary to frequently change the wind direction.

[0117] (5-3) Variation 1C

[0118] In the blowing unit 1 of the first embodiment, the air blowing portion of the blowing port P is formed in one part between the plate member 10 and the guide portion 200; however, in the modified example 1C, it is formed in two parts.

[0119] like Figures 7A-7C As shown, in the blowing unit 1c of modified example 1C, two plate members 10a and 10b and a guide portion 200a are arranged at the blowing port P of the chamber box 30c. The plate members 10a and 10b are arranged such that they sandwich the guide portion 200a and are parallel in their long side direction. An air blowing portion, i.e., a first blowing port P1, is formed between the plate member 10a and the guide portion 200a, and a second blowing port P2 is formed between the plate member 10b and the guide portion 200a. The guide portion 200a has a first surface 210a on the plate member 10a side and a first surface 210b on the plate member 10b side. The guide portion 200a is fixed to the chamber box 30c at both ends in its long side direction. Figure 7A , 7B In this configuration, the first surfaces 210a and 210b are concave curved surfaces extending from the ventilation duct S towards the interior 3 side; however, they could also be planar. The first surface 210a, at a cross-section (hereinafter referred to as cross-section Y) perpendicular to the outlet P and extending from the plate member 10a along the plate member 10b, slopes from the ventilation duct S towards the interior 3 side in a direction from the center portion of the guide portion 200a near the plate member 10a. The first surface 210b, at cross-section Y, slopes from the ventilation duct S towards the interior 3 side in a direction from the center portion of the guide portion 200a near the plate member 10b. In other words, the center portion of the guide portion 200a at cross-section Y, i.e., between the first surfaces 210a and 210b, protrudes from the outlet P1, P2 side towards the ventilation duct S side. The plate members 10a and 10b rotate in the opposite direction from the outlet P towards the ventilation duct S. The structure of the blowing unit 1c, other than the above-described structure, is the same as that of the blowing unit 1 in the first embodiment.

[0120] Air supplied to ventilation duct S flows in the first wind direction F1 within ventilation duct S, branching to the first outlet P1 and the second outlet P2 before being blown out into room 3. At the first outlet P1, the blowing direction, i.e., the second wind direction F23a, changes due to the rotation of the plate member 10a. As the rotation angle of the plate member 10a increases from the horizontal direction, the change in the angle of the second wind direction F23a from the first wind direction F1 decreases. In other words, the angle between the second wind direction F23a and the horizontal increases. Similarly, at the second outlet P2, the blowing direction, i.e., the second wind direction F23b, changes due to the rotation of the plate member 10b. As the rotation angle increases from the horizontal direction, the change in the angle of the second wind direction F23b from the first wind direction F1 decreases. In other words, the angle between the second wind direction F23b and the horizontal increases.

[0121] In the blowing unit 1c of modified example 1C, the second airflow direction F23a and the second airflow direction F23b can be controlled independently. In other words, the rotation angles of plate member 10a and plate member 10b can be controlled independently. Furthermore, both blowing outlets P1 and P2 can be opened together, both can be closed together, or one of the blowing outlets P1 and P2 can be opened while the other is closed.

[0122] (5-4) Variation 1D

[0123] In the blowing unit 1 of the first embodiment, the air blowing portion of the blowing port P is formed in one part between the plate member 10 and the guide portion 200; however, in the modified example 1D, it is formed in four parts.

[0124] In the blowing unit 1d of variant example 1D, as Figures 8-10 As shown, four plate members 10a to 10d and a guide portion 200b are arranged at the blow-out port P of the chamber 30d. Plate members 10a and 10c are arranged such that they sandwich the guide portion 200b and their long sides are parallel. Plate members 10b and 10d are arranged such that they sandwich the guide portion 200b and their long sides are parallel. The long sides of plate members 10a and 10c are orthogonal to the long sides of plate members 10b and 10d. When viewed from the interior side of the blow-out unit 1d, the plate members 10a to 10d are arranged to surround the four sides of the second surface of the rectangular guide portion 200b. Air blowing portions, namely four blow-out ports P1 to P4, are formed between the plate members 10a to 10d and the guide portion 200b. The guide portion 200b has a first surface 210a to 210d on the side of the plate members 10a to 10d. The first surfaces 210a to 210d slope from the ventilation duct S towards the interior 3 side in a direction from the center portion of the guide portion 200b near the plate member 10a. The guide portion 200b may have its center portion fixed to the upper surface of the inner side of the chamber box 30d by a support member.Figure 8 The first surfaces 210a to 210d are flat surfaces in this embodiment, but can be curved surfaces recessed toward the indoor 3 side from the duct S side. The structure other than the above-described structure of the blow-out unit Id is the same as that of the blow-out unit 1 of the first embodiment.

[0125] In the blow-out unit Id of the modification example 1D, the air supplied to the duct S flows in the first air direction Fl within the duct S, and is blown out to the indoor 3 by being branched to the blow-out ports P1 to P4. At the blow-out ports P1 to P4, the blow-out direction, that is, the second air direction F23a is changed by the rotation of the plate members 10a to 10d. As the rotation angle becomes larger from the horizontal direction, the change in the angle of the second air direction F24a to F24d from the first air direction Fl becomes smaller. In other words, the angle of the second air direction F24a to F24d from the horizontal direction becomes larger.

[0126] In the blow-out unit Id of the modification example 1D, the blow-out direction of the air from the blow-out ports P1 to P4 toward the indoor, that is, the second air direction, can be independently controlled for each of the blow-out ports P1 to P4. In other words, the rotation angle of the plate members 10a to 10d can be independently controlled. Further, it is possible to open all of the blow-out ports P1 to P4, to close all of them, or to open a part of the blow-out ports P1 to P4 and close the other part.

[0127] (5-5) Modification Example 1E

[0128] The blow-out unit le of the modification example 1E is a part of an air conditioning device. The air conditioning device performs air conditioning such as heating, cooling, dehumidification, humidification, and the like of the indoor. The air conditioning device includes, in addition to the blow-out unit, a fan, a heat exchanger, and the like. In the blow-out unit le, the duct S is formed inside the air conditioning device, and thus, unlike the blow-out unit 1 of the first embodiment, does not have the chamber box 30. The blow-out port P is a blow-out port of the air conditioning device. The blow-out unit le can also not have the panel 33. The structure other than the above-described structure of the blow-out unit le is the same as that of the blow-out unit 1 of the first embodiment.

[0129] <Second Embodiment>

[0130] (6) Structure of Blow-out Unit 100

[0131] The blow-out unit 100 is disposed at the blow-out port P of the duct S toward the indoor 3, and blows out the air supplied through the duct S to the indoor 3. Here, the supplied air includes outside air, air in which air of the indoor 3 is heated, cooled, dehumidified, humidified, and the like. The blow-out port P is disposed at a ceiling surface or a wall surface of a room. The blow-out unit 100 is disposed at the duct S side from the blow-out port P and at the back surface of the ceiling, the back surface of the side wall.

[0132] The blow-out unit 100 will be described with reference to the drawings.Figure 11 is a perspective view of the blow-out unit 100 as viewed obliquely from below with the blow-out unit 100 disposed on the back surface of the ceiling. Figure 12 is a vertical sectional view schematically showing the air flow of the blow-out unit 100. Figure 13A 、 13B is a vertical sectional view of the blow-out unit 100, Figure 13A is a view of the first plate member 10 and the second plate member 20 in the first state, Figure 13B is a view in the second state. Figure 16 is a control block diagram of the blow-out unit 100.

[0133] The blow-out unit 100 includes the first plate member 10, the second plate member 20, the chamber case 30, the panel 33, the control section 40, the first motor 41, and the second motor 42. The chamber case 30 is in a box shape, has a suction port connected to a duct and a blow-out port that blows out air. The structure of the chamber case 30 will be described later. The blow-out unit 100 is disposed on the back surface of the ceiling with the blow-out port of the chamber case 30 located at the opening portion of the ceiling surface 2 of the room. The chamber case 30 constitutes a part of the ventilation passage S, and the blow-out port of the chamber case 30 constitutes the blow-out port P of the ventilation passage S. The first plate member 10 and the second plate member 20 are disposed at the blow-out port P. In the present embodiment, the blow-out port P is rectangular as viewed from the room side. The panel 33 is disposed on the ceiling surface from the room side so as to cover the periphery of the blow-out port P of the ceiling surface. The blow-out unit 100 blows out air supplied through the chamber case 30 to the room 3 by rotation of the first plate member 10 and the second plate member 20.

[0134] The first plate member 10 and the second plate member 20 are disposed in one set at the blow-out port P of the chamber case 30. One is referred to as the first plate member, and the other is referred to as the second plate member.

[0135] The first plate member 10 is a rectangular plate having a prescribed thickness, and is disposed so that its face is parallel to the ceiling surface. The face of the first plate member 10 on the room side is referred to as the first face 101, and the face on the ventilation passage S side is referred to as the second face 102. The first plate member 10 has a first edge 11a that extends in the long direction and opposes the second plate member 20, and a second edge 12a that extends in parallel to the first edge 11a and faces the first wall face 30a of the chamber case 30. The length of the first plate member 10 in the long direction is substantially the same as the length of the blow-out port P in the long direction. As Figure 13AAs shown, the first plate member 10 has a first end 11 near the second plate member 20 at a cross section (hereinafter referred to as section X) perpendicular to the outlet P and along the direction from the first plate member 10 along the second plate member 20. The second end 12 is near the first wall surface 30a of the chamber box 30 (ventilation duct S). The first end 11 is located on the first side 11a of the first plate member 10, and the second end 12 is located on the second side 12a of the first plate member 10.

[0136] The shape of the first plate member 10 can be appropriately changed according to the shape of the blow-out port P. The first plate member 10 can also be rectangular or square. The corners of the first plate member 10 can also be chamfered. The thickness of the first plate member 10 can also be non-uniform, and its thickness can decrease from the center of the first plate member 10 toward the four ends.

[0137] The first plate member 10 has a first pivot 15 near the second end 12. The distance between the first pivot 15 and the second end 12 is less than 1 / 3 of the distance between the first end 11 and the second end 12 of the first plate member 10. More preferably, the distance between the first pivot 15 and the second end 12 is less than 1 / 2 of the thickness of the first plate member 10. As a result, when the first plate member 10 is rotated, the amount of air flowing between the first plate member 10 and the wall of the chamber box 30 can be reduced. In addition, when the first plate member 10 is rotated, the situation where the second end 12 protrudes towards the indoor side of the outlet P can be suppressed. The first plate member 10 can rotate 90° around the first pivot 15. The first plate member 10 can also rotate from 0° to an angle of more than 45° and less than 90° in the direction of the ventilation duct S around the first pivot 15.

[0138] The first plate component 10 only needs to be able to rotate within the range that allows for wind direction adjustment.

[0139] like Figure 13A As shown, when the first plate member 10 is at the blow-out port P, the first plate member 10 is said to be in the first state. Figure 13B As shown, when the first plate component 10 rotates around the first pivot 15 and moves to the ventilation duct S, it is said to be in the second state.

[0140] The second plate member 20 is a rectangular plate with a specified thickness, configured such that its surface is parallel to the ceiling surface. The interior side of the second plate member 20 is designated as the first surface 201, and the side facing the ventilation duct S is designated as the second surface 202. The second plate member 20 has a first side 21a and a second side 22a, wherein the first side 21a extends in the longitudinal direction and is opposite to the first plate member 10, and the second side 22a extends parallel to the first side 21a and faces the second wall surface 30b of the chamber box 30. The length of the second plate member 20 in the longitudinal direction is approximately the same as the length of the outlet P in the longitudinal direction.Figure 13A As shown, the second plate member 20 has a first end portion 21 near the first plate member 10 at the cross section X and a second end portion 22 near the second wall surface 30b of the chamber case 30 (the air passage S).

[0141] The shape of the second plate member 20 can be appropriately changed according to the shape of the blowout port P. The second plate member 20 can also be rectangular, and can also be square. The corners of the second plate member 20 can also be chamfered. The thickness of the second plate member 20 can also not be uniform, and can decrease from the central portion of the second plate member 20 toward the end portions of the four sides.

[0142] The second plate member 20 has a second pivot 25 near the second end portion 22. The distance of the second pivot 25 from the second end portion 22 is 1 / 3 or less of the distance of the first end portion 21 of the second plate member 20 from the second end portion 22. More preferably, the distance of the second pivot 25 from the second end portion 22 is 1 / 2 or less of the thickness of the second plate member 20. Thus, in the case where the second plate member 20 is rotated, the amount of air flowing between the second plate member 20 and the second wall surface 30b of the chamber case 30 can be reduced. Further, in the case where the second plate member 20 is rotated, the second end portion 22 can be inhibited from protruding toward the indoor side more than the blowout port P. The second plate member 20 can be rotated 90° about the second pivot 25. The second plate member 20 can also be able to be rotated from 0° to an angle of 45° or more and less than 90° in the direction of the air passage S about the second pivot 25. The second plate member 20 can be rotated in a range in which the air direction can be adjusted.

[0143] As shown, the second plate member 20 is in the first state when the second plate member 20 is in the blowout port P. As shown, the second plate member 20 is in the second state when the second plate member 20 is moved to the air passage S by being rotated about the second pivot 25. Figure 13A Figure 13B As shown, the second plate member 20 is in the first state when the second plate member 20 is in the blowout port P. As shown, the second plate member 20 is in the second state when the second plate member 20 is moved to the air passage S by being rotated about the second pivot 25.

[0144] As shown, the first plate member 10 is rotated counterclockwise from the first state to the second state. On the other hand, the second plate member 20 is rotated clockwise from the first state to the second state. Figure 13A 13B As shown, the first plate member 10 is rotated counterclockwise from the first state to the second state. On the other hand, the second plate member 20 is rotated clockwise from the first state to the second state.

[0145] As shown, the first plate member 10 is rotated counterclockwise from the first state to the second state. On the other hand, the second plate member 20 is rotated clockwise from the first state to the second state. Figure 13A ​​As shown, when both the first plate member 10 and the second plate member 20 are in the first state, the blowout port P is closed. At this time, the first end portion 11 of the first plate member 10 opposes the first end portion 21 of the second plate member 20. Further, the first face 101 of the first plate member 10 and the first face 201 of the second plate member 20 are disposed on the same horizontal plane. The first face 101 of the first plate member 10 and the first face 201 of the second plate member 20 can also not be disposed on the same plane, either one of which can be disposed on the side of the air duct S than the other.

[0146] When either one or both of the first plate member 10 and the second plate member 20 is in the second state, the blowout port P is opened. Figure 12 、 Figure 13B In the case shown in FIG. 6, both the first plate member 10 and the second plate member 20 are in the second state. As shown, by making the rotation angles of the first plate member 10 and the second plate member 20 different, it is possible to change the direction of the air. Further, by the rotation angles of the first plate member 10 and the second plate member 20, it is possible to change the arrival distance Dl of the air. Figure 12

[0147] The chamber box 30 constitutes a part of the air duct S. The chamber box 30 is disposed on the back surface of the ceiling or the side wall. The chamber box 30 is of a box shape, has a suction port connected to a duct and a blowout port that blows out air. The suction port can be connected to an air handling unit such as a ventilation device, an air conditioning device, or the like, through a duct. The blowout port is substantially the same shape as the opening portion of the ceiling surface. The chamber box 30 has four wall surfaces that extend perpendicularly with respect to the blowout port P. The blowout port P is constituted by the end portions of the four wall surfaces. The four wall surfaces include a first wall surface 30a on the side of the first plate member 10 at the cross section X and a second wall surface 30b on the side of the second plate member 20. The suction port of the chamber box 30 can also be formed on the upper portion of the chamber box 30, or on the side wall surface. In the case shown in FIG. 5, the suction port is formed on the second wall surface 30b. In the present embodiment, the chamber box 30 constitutes the air duct S, but the chamber box 30 is not essential. Figure 13A 、 13B In the present embodiment, the chamber box 30 constitutes the air duct S, but the chamber box 30 is not essential.

[0148] ​The panel 33 is arranged on the ceiling surface 2 from the indoor side so as to cover the periphery of the blow-out port P of the ceiling surface 2. The panel 33 is a frame having a prescribed thickness, which extends from the ceiling surface to a portion of the inner side of the blow-out port P. The panel 33 covers a portion of the second end portion 12 side of the first plate member 10 from the ceiling surface 2 at the cross section X, and covers a portion of the second end portion 22 of the second plate member 20 from the ceiling surface 2. The panel 33 has a face on the indoor side at a position further toward the indoor side than the first face 101 of the first plate member 10 and the first face 201 of the second plate member 20. Alternatively, the face on the indoor side of the panel 33 can be arranged in parallel with the first face 101 of the first plate member 10 and the first face 201 of the second plate member 20 on the same plane. The panel 33 can also cover only the ceiling surface, but by extending to a portion of the inner side of the blow-out port P, it is possible to suppress air from being blown out from between the second end portion 12 of the first plate member 10 and the first wall surface 30a of the chamber case 30, and between the second end portion 22 of the second plate member 20 and the second wall surface 30b of the chamber case 30. The panel 33 covers the gap between the blow-out port of the chamber case 30, the first plate member 10, and the second plate member 20, and the wall surface of the chamber case 30, and is not visible from the indoor side 3, so the appearance of the blow-out unit 100 is improved, but this is not necessary.

[0149] The first motor 41 rotates the first plate member 10. The second motor 42 rotates the second plate member 20. In other words, the first plate member 10 and the second plate member 20 are independently rotated. The first motor 41 and the second motor 42 can be step motors. The first motor 41 and the second motor 42 can be arranged inside the chamber case 30, or can be arranged outside.

[0150] Figure 16 A control block diagram of the blow-out unit 100 is shown. The control section 40 controls the first motor 41 and the second motor 42. The control section 40 is a computer. The control section 40 includes a processor and a storage section. The control section 40 can also be a microcomputer. The location where the control section 40 is arranged is not particularly limited. The control section 40 can also control a plurality of blow-out units 100 at the same time. The control section 40 can also be used for control of other components of the air conditioning device. For example, it can also be used as a control section for a heat exchanger that heats or cools air supplied to the indoor 3. The control section 40 can also perform control in cooperation with the control sections of the other components described above.

[0151] The control section 40 can perform control by an instruction from a remote controller operated by a user.

[0152] (7) Control of the reach distance D1 of air of the blow-out unit 100

[0153] To investigate how the arrival distance D1 of the air blown from the blowout port P to the room 3 changes when the rotation angles of the first and second plate members 10 and 20 of the blowout unit 100 are changed, a simulation was performed. As the simulation conditions, the entire system was set to an isothermal field, and the blowout air volume was set to 10 m 3 / minute. Figures 14A-14C The results thereof are shown in FIGS. 8A to 8C. Figures 14A-14C The upper graph of each shows the rotation angles of the first and second plate members 10 and 20, and the lower graph of each shows the region in which a wind speed of 1 m / s or more can be obtained. In this simulation, as understood from Figures 14A-14C the rotation angles of the first and second plate members 10 and 20 are the same. In other words, the first and second plate members 10 and 20 are rotated in a symmetric manner about the center line.

[0154] Figure 14A The rotation angles of the first and second plate members 10 and 20 are 30° from the horizontal plane. In this case, the blown air reaches from the ceiling 2 to the floor of the room 3. The arrival distance D1 is 2.6 m. Figure 14B The rotation angles of the first and second plate members 10 and 20 are 50° from the horizontal plane. In this case, the arrival distance D1 of the blown air is 2.1 m. Figure 14C The rotation angles of the first and second plate members 10 and 20 are 65° from the horizontal plane. In this case, the arrival distance D1 of the blown air is 1.6 m. As understood from Figures 14A-14C the arrival distance D1 decreases as the rotation angles of the first and second plate members 10 and 20 increase.

[0155] (8) Control of the wind direction of the blowout unit 100

[0156] Next, to investigate how the wind direction of the air blown from the blowout port P to the room 3 changes when the rotation angles of the first and second plate members 10 and 20 of the blowout unit 100 are changed, a simulation was performed. As the simulation conditions, the entire system was set to an isothermal field, and the blowout air volume was set to 10 m 3 / minute. Figures 15A-15E The results thereof are shown in FIGS. 9A to 9C. Figures 15A-15E The upper graph of each shows the rotation angles of the first and second plate members 10 and 20, and the lower graph of each shows the region in which a wind speed of 1 m / s or more can be obtained. In this simulation, in Figures 15A-15D the rotation angle of the first plate member 10 is smaller than the rotation angle of the second plate member 20. The wind direction of the air blown from the blowout port P is tilted toward the second plate member 20 side. Figure 15E the rotation angle of the first plate member 10 is the same as the rotation angle of the second plate member 20. The wind direction of the air blown from the blowout port P is the vertical direction.

[0157] Figure 15A In this case, the rotation angle of the first plate member 10 is 15° from the horizontal, and the rotation angle of the second plate member 20 is 52° from the horizontal. The wind direction (airflow angle) is inclined to the second plate member 20 side, and is 20° from the horizontal. Figure 15B In this case, the rotation angle of the first plate member 10 is 16° from the horizontal, and the rotation angle of the second plate member 20 is 50° from the horizontal. The wind direction (airflow angle) is inclined to the second plate member 20 side, and is 30° from the horizontal. Figure 15C In this case, the rotation angle of the first plate member 10 is 30° from the horizontal, and the rotation angle of the second plate member 20 is 52° from the horizontal. The wind direction (airflow angle) is inclined to the second plate member 20 side, and is 45° from the horizontal. Figure 15D In this case, the rotation angle of the first plate member 10 is 35° from the horizontal, and the rotation angle of the second plate member 20 is 52° from the horizontal. The wind direction (airflow angle) is inclined to the second plate member 20 side, and is 65° from the horizontal. Figure 15E In this case, the rotation angle of the first plate member 10 and the rotation angle of the second plate member 20 are both 52° from the horizontal. The wind direction (airflow angle) is the vertical direction.

[0158] As described in (2) or (3) above, the wind direction of the blown air depends on the rotation angles of the first plate member 10 and the second plate member 20. According to a preliminary experiment, the rotation angles of the first plate member 10 and the second plate member 20 and the wind direction of the blown air are stored in the storage section of the control section 40. The control section 40 controls the rotation angles of the first plate member 10 and the second plate member 20 using the data stored in the storage section to make the wind direction of the blown air reach a prescribed wind direction when air conditioning of the room is performed.

[0159] (9) Features

[0160] (9-1)

[0161] The blow-out unit 100 of the present embodiment is disposed at the blow-out port P of the ventilation passage S facing the room 3, and blows out the air supplied through the ventilation passage S to the room 3. The blow-out unit 100 has a first plate member 10 and a second plate member 20. The first plate member 10 rotates around a first rotation shaft 15, and moves from a first state disposed at the blow-out port P to a second state inside the ventilation passage S. Similarly, the second plate member 20 rotates around a second rotation shaft 25, and moves from a first state disposed at the blow-out port P to a second state inside the ventilation passage S. Further, in the first state, the first edge 11a of the first plate member 10, which is distal from the first rotation shaft 15, is disposed to oppose the first edge 21a of the second plate member 20, which is distal from the second rotation shaft 25.

[0162] Based on this structure, the blowing unit 100 of this embodiment can change the wind direction and the distance D1 of the air blown out from the blowing port P by changing the rotation angle of the first plate member 10 and the second plate member 20.

[0163] (9-2)

[0164] The first plate component 10 is roughly rectangular in shape, such as... Figure 13A As shown, the device has a first side 11a on the side of the second plate member 20 in the first state, a second side 12a on the side of the first wall surface 30a of the ventilation duct S (or chamber box 30), and a first pivot 15. The first pivot 15 is closer to the second side 12a than the first side 11a. The distance between the first pivot 15 and the second side 12a is less than 1 / 3 of the distance between the first side 11a and the second side 12a of the first plate member 10. In other words, the first pivot 15 passes through 1 / 3 of the length of the first plate member 10 from the second side 12a and is positioned between a straight line orthogonal to the outlet P and the first wall surface 30a.

[0165] Similarly, the second plate member 20 is approximately rectangular in shape, such as... Figure 13A As shown, the second plate member 20 has a first side 21a on the side of the first plate member 10, a second side 22a on the side of the second wall surface 30b of the ventilation duct S (or chamber box 30) in the first state, and a second pivot 25. The second pivot 25 is closer to the second side 22a than the first side 21a. The distance between the second pivot 25 and the second side 22a is less than 1 / 3 of the distance between the first side 21a and the second side 22a. In other words, the second pivot 25 passes through 1 / 3 of the length of the second plate member 20 from the second side 22a and is positioned between a straight line orthogonal to the outlet P and the second wall surface 30b.

[0166] An air-blowing portion of the outlet P is formed at one location between the first plate member 10 and the second plate member 20. No air-blowing portion is formed between the first plate member 10 and the first wall surface 30a, or between the second plate member 20 and the second wall surface 30b.

[0167] With this structure, the air outlet P of this embodiment can be easily controlled in terms of air direction and distance D1.

[0168] (9-3)

[0169] In the blowing unit 100 of this embodiment, in the first state, the first surface 101 of the first plate member 10 and the first surface 201 of the second plate member 20 are disposed on approximately the same surface as the ceiling 2. Therefore, even when the blowing unit 100 is installed on the ceiling 2, the blowing unit 100 is not conspicuous and has excellent appearance.

[0170] (9-4)

[0171] The blow-out unit 100 of the present embodiment further includes a chamber case 30 that constitutes a part of the ventilation passage S. The chamber case 30 is disposed at the back of the ceiling or the back of the side wall. The chamber case 30 has a first wall surface 30a on the first plate member 10 side and a second wall surface 30b on the second plate member 20 side. The chamber case 30 is formed with an opening portion that constitutes the blow-out port P. The first plate member 10 and the second plate member 20 are disposed in the opening portion.

[0172] (9-5)

[0173] The first plate member 10 and the second plate member 20 are disposed in parallel in the first state in a manner that closes the blow-out port P. In other words, the first edge 11a of the first plate member 10 is parallel to the first edge 21a of the second plate member 20, and the interval between them is small.

[0174] Therefore, by switching the first state and the second state of the first plate member 10 and the second plate member 20, the opening and closing of the blow-out port P can be performed.

[0175] (9-6)

[0176] The blow-out unit 100 of the present embodiment further includes a control section 40, a first motor 41, and a second motor 42.

[0177] The first motor 41 rotates the first plate member 10. The second motor 42 rotates the second plate member 20. The control section 40 controls the first motor 41 and the second motor 42. The control section 40 controls the first plate member 10 and the second plate member 20 to appropriate angles by controlling the first motor 41 and the second motor 42, thereby controlling the air direction and the arrival distance D1 of the air.

[0178] (10) Modification

[0179] (10-1) Modification 2A

[0180] The blow-out unit of Modification 2A is structurally the same as the blow-out unit 100 of the second embodiment except that it does not have a motor and a control section. The blow-out unit 100 of Modification 2A always uses the rotation angle of the first plate member 10 and the rotation angle of the second plate member 20 in the same state. In the case where the rotation angles are changed, the change is performed in a manual manner.

[0181] The blow-out unit of Modification 2A is used in a situation where the air direction does not need to be changed frequently.

[0182] (10-2) Modification 2B

[0183] In the blowing unit 100 of the second embodiment, the air blowing portion of the outlet P is formed at one location between the first plate member 10 and the second plate member 20; however, in the modified example 2B, it is formed at two locations. In the blowing unit 100a of the modified example 2B, as... Figure 17 As shown, first plate members 10x and 10y and second plate members 20x and 20y are disposed at the outlet P of the chamber 30x. The first plate member 10x and the second plate member 20x are arranged in a direction perpendicular to the long side direction of the outlet P. The first plate member 10y and the second plate member 20y are arranged in a direction perpendicular to the long side direction of the outlet P. The first plate member 10x and the first plate member 10y are arranged along the long side direction of the outlet P. The second plate members 20x and the second plate member 20y are arranged along the long side direction of the outlet P. An air outlet portion, namely the first outlet P1, is formed between the first plate member 10x and the second plate member 20x. An air outlet portion, namely the second outlet P2, is formed between the first plate member 10y and the second plate member 20y. The structure and operation of the first plate members 10x and 10y and the second plate members 20x and 20y are the same as those of the first plate member 10 and the second plate member 20 in the second embodiment.

[0184] Panel 33a has a portion disposed between the first plate member 10x and the second plate member 20x and the first plate member 10y and the second plate member 20y, and extending in a direction perpendicular to the long side direction of the blow-out port P. The structure of the blow-out unit 100a, other than the structure described above, is the same as that of the blow-out unit 100 in the second embodiment.

[0185] In the blowing unit 100a of Modified Example 2B, the airflow direction at the first blowing outlet P1 and the distance D1 of the blown air can be controlled by controlling the rotation angle of the first plate member 10x and the rotation angle of the second plate member 20x. Similarly, the airflow direction at the second blowing outlet P2 and the distance D1 of the blown air can be controlled by controlling the rotation angle of the first plate member 10y and the rotation angle of the second plate member 20y.

[0186] By setting the rotation angles of the first plate member 10x and the first plate member 10y to be the same, and controlling the rotation angles of the second plate member 20x and the second plate member 20y to be the same, the wind direction at the first outlet P1, the distance D1 of the blown air, and the wind direction at the second outlet P2, and the distance D1 of the blown air can be controlled to be approximately the same.

[0187] Further, by making any one or both of the rotation angles of the first plate members 10x and 10y and the rotation angles of the second plate members 20x and 20y different, it is possible to control the wind directions at the first blowout port P1 and the second blowout port P2 and the reaching distances D1 of the blowout air in such a way that they are different.

[0188] Further, in Figure 17 , the faces of the ceiling surface 2, the panel 33a, the indoor sides of the first plate members 10x and 10y, and the second plate members 20x and 20y are configured to lie on substantially the same plane. Thereby, the aesthetic appearance of the blowout unit 100a becomes excellent.

[0189] (10-3) Modification 2C

[0190] In the blowout unit 100 of the second embodiment, the first rotation shaft 15 of the first plate member 10 can be located outside the first plate member 10, and the second rotation shaft 25 of the second plate member 20 can be located outside the second plate member 20. The first rotation shaft 15 can also not be located between the extension plane of the first face 101 and the extension plane of the second face 102 of the first plate member 10. The second rotation shaft 25 can also not be located between the extension plane of the first face 201 and the extension plane of the second face 202 of the second plate member 20.

[0191] Regarding the structure of the blowout unit 100b of Modification 2C, as Figure 18 indicated, the structure is the same as that of the blowout unit 100 of the second embodiment except for the points that the first rotation shaft 15 is located outside the first plate member 10 and the second rotation shaft 25 is located outside the second plate member 20.

[0192] In the blowout unit 100b of Modification 2C, in Figure 18 a cross-sectional view, the first plate member 10 has a first end portion 11 of a first edge and a second end portion 12 facing a first wall surface 30a of the air duct S. A rotation metal piece is fixed to the first plate member 10 and the first wall surface 30a, and the first plate member 10 rotates around the first rotation shaft 15 of the rotation metal piece. The second plate member 20 has a first end portion 21 of a first edge and a second end portion 22 facing a second wall surface 30b of the air duct S. A rotation metal piece is fixed to the second plate member 20 and the second wall surface 30b, and the second plate member 20 rotates around the second rotation shaft 25 of the rotation metal piece. The first rotation shaft 15 and the second rotation shaft 25 of the rotation metal piece can be rotated by a motor or manually.

[0193] The above describes the embodiments of the present disclosure, but it should be understood that various modifications in form and details can be made without departing from the spirit and scope of the present disclosure as recited in the claims.
