  The present invention relates to an air outlet device having a long air outlet that blows out wind introduced from an inlet.

  2. Description of the Related Art Conventionally, in an air conditioner used for a vehicle such as an automobile, the air outlet device provided in the air outlet that blows out the wind is also called an air conditioner air outlet device, an air outlet, a ventilator, a register, and the like. It is installed in each part of the vehicle and contributes to the improvement of comfort performance by air conditioning.

  In recent years, for example, a blower outlet device used in a vehicle such as a concept car that emphasizes design is sometimes required to be thin and long in the longitudinal direction and short in the lateral direction.

  As such an air outlet device, a pair of fins are arranged along the longitudinal direction of the long air outlet provided in the case body connected to the duct of the air conditioner, and both ends of each of the fins making the pair Support shafts project from the windward side and leeward side of the part, and a drive gear is provided for transmitting the driving force to these fins and tilting the fins, and depending on the direction of rotation of the drive gear, There is known a configuration in which a pair of intermittent gears that select whether or not to mesh and change the tilting mode of each fin is provided (see, for example, Patent Document 1). In this configuration, the fin can be largely tilted by changing the center of tilt between the windward support shaft and the leeward support shaft according to the tilting mode of the paired fins, while maintaining directivity. The company is trying to make it thinner.

  In addition, a long outlet in the left-right direction is provided on the other end of the case body, one end of which is connected to the duct of the air conditioner, and the inner surface of the case body facing the upper and lower long sides facing each other A first inclined surface that is inclined in an expanding manner toward the air outlet is provided, and a second inclined surface that is inclined in an expanding manner toward the anti-air outlet side continuously through the ridge line with respect to the first inclined surface. And the first inclined fins are arranged in the vicinity of the air outlet along the long side of the air outlet, and the first inclined fins are arranged in the vicinity of the air outlet. A configuration is known in which a plurality of second fins are arranged on the windward side of the first fin in a direction orthogonal to the fins (see, for example, Patent Document 2). In this configuration, the air distribution performance is ensured by the inclination of each inclined surface and each fin by rotating each fin.

  Furthermore, the introduction port through which the air from the air conditioner is introduced, the first air outlet that is opened outward in the vehicle width direction, and the length that is open to a range that is adjacent to the air outlet and extends to the center in the vehicle width direction. A case body having a second air outlet, and a first supply port for supplying the introduced air to the first air outlet side at all times in a ventilation path inside the case body, and a second air outlet. The structure which provided the rotation duct which has the 2nd supply port to turn is known (for example, refer patent document 3). In this configuration, when the second air outlet is closed by rotating the rotating duct, a direct wind (spot air) having a high wind speed and a large air volume is blown out only from the first air outlet through the first supply port. When the second air outlet is opened, an indirect wind (mild air) with a reduced wind speed is blown out from the second supply port and the second air outlet.

Further, the fins 14 and 15 are accommodated in the front end portions of the upper wall portion 25 and the lower wall portion 26, that is, the end portions on the leeward side, in other words, the end portions connected to the back side of the finisher 22 ( Concave portions 33 and 34 (one and the other) are continuous in a long shape in the left-right direction across both side wall portions 27 and 27, respectively. Round hole bearings 36 and 37 that pivotally support the fins 14 and 15 are opened at the upper and lower ends of the front ends of the side walls 27 and 27 so as to communicate with the recesses 33 and 34. ing. In one side wall portion, in this embodiment, for example, the left side wall portion 27, a circular attachment hole 38 for attaching the opening / closing means 16 is opened.

  The introduction port 31 is connected to a duct portion communicating with an air conditioner (not shown), and introduces air from the air conditioner into the ventilation path 32 linearly along the axial direction of the front-rear direction (case body 13).

  The recesses 33 and 34 are located inside the ventilation path 32, and are continuous at a substantially constant depth along the left-right direction that is the longitudinal direction of the case body 13 (case body main body 21).

  The finisher 22 is formed in a rectangular frame shape and divides the periphery of a long rectangular (slit-shaped) outlet 41 that communicates with the ventilation path 32 and blows the air introduced into the ventilation path 32 from the introduction port 31. doing. Accordingly, the air outlet 41 is located at the other end (front end) of the case body 13, and the recesses 33 and 34 are located along the long sides 41a and 41a that are opposite sides of the air outlet 41. Yes. The finisher 22 is airtightly connected to the front end of the case body 21 and is open / close means 16 at a position spaced laterally with respect to, for example, the left outlet 41 on one end in the longitudinal direction. A part of the opening for operation 42 is formed in the shape of a long hole along the vertical direction.

  The outlet 41 has a shape that is long in the left-right direction and short in the up-down direction. The air outlet 41 is formed in a thin shape whose longitudinal dimension is, for example, 2 times or more, more preferably 5 times or more of the short dimension. Further, the upper and lower edges, which are the long sides of the air outlet 41, are inclined surfaces 43, 43 that are inclined in an expanding manner toward the front side, which is the leeward side. Further, the air outlet 41 is not provided with a wind direction control body (fin) for controlling the air direction, and the air outlet 41 is merely an opening.

  The fins 14 and 15 are also called horizontal louvers or the like, and are arranged with the left-right direction as the longitudinal direction. The fins 14 and 15 are pivotally supported by the bearing portions 36 and 37 of the case body 13 so as to be rotatable about the horizontal direction, that is, the horizontal direction as a rotation axis, respectively, and the upper and lower edges of the blower outlet 41 on the back side of the finisher 22 Is located. That is, these fins 14 and 15 are (one and the other) fin bodies 45 and 46 as long rectangular plate-like (one and the other) rotating blade bodies that control the opening area of the air passage 32, and these Cylindrical (one and other) rotation shafts 47, 48 that protrude from the longitudinal direction of the fin bodies 45, 46, that is, from both left and right ends, and are rotatably supported by bearings 36, 37; Are integrally provided, and can be rotated in the vertical direction with respect to the case body 13.

  The fin bodies 45 and 46 are formed with a thickness that fits into the recesses 33 and 34. That is, the fin bodies 45 and 46 are substantially flush with the surfaces of the upper wall portion 25 and the lower wall portion 26 on the side of the ventilation path 32 in a state where the fin main bodies 45 and 46 are fitted in the recesses 33 and 34. In addition, the front-rear direction of the fin bodies 45, 46, that is, the dimension in the short direction is larger than 1/2 of the vertical dimension of the ventilation path 32 (vertical dimension of the air outlet 41). For example, the short dimension of the fin body 45 is set larger than the short dimension of the fin body 46. The lower surface of the fin body 45 and the upper surface of the fin body 46, that is, the mutually opposing main surfaces of the fin bodies 45, 46 are flat (one and the other) rectifiers that rectify the wind. Surfaces 51 and 52 are formed.

  The rotating shaft portions 47 and 48 are projected from the fin bodies 45 and 46 at the positions of the front end portions of the fins 14 and 15, that is, the end portions on the air outlet 41 side. Since these rotation shaft portions 47 and 48 are pivotally supported by the bearing portions 36 and 37 at fixed positions, the finisher 22 is viewed from above or below the upper and lower edges of the air outlet 41, that is, from the front side (leeward side). It is a hidden position on the back side.

  The opening / closing means 16 includes a dial 55 as an operated portion, a screw 56 as a mounting member for rotatably mounting the dial 55 to one side wall portion 27, and a shaft 55 that is pivotally supported by the screw 56 and integrated with the dial 55. A rotating gear 57 that rotates in a straight line, driven gears 58 and 59 (one and the other) connected to one end of the rotating shaft portions 47 and 48 of the fins 14 and 15, and a rotating gear 57 and a driven gear. And a connection gear 60 for connecting the motor 58 and the motor 58. The opening / closing means 16 is arranged outside the case body 13 and inside the instrument panel 11 at one end (left end) in the longitudinal direction of the case body 13.

  The dial 55 is formed in a circular shape, and an insertion hole 63 such as a circular hole into which a screw 56 is inserted is opened at the center. The dial 55 is located along the side portion of one (left side) side wall portion 27 and has an axial direction along the left-right direction (horizontal direction). The dial 55 is located at one end (left end) in the longitudinal direction of the case body 21 and on the back surface of the finisher 22, and the front portion of the finisher 22 from the operation opening 42 of the finisher 22 is the finisher 22 (case body 13). A user such as an occupant of the vehicle can rotate in the vertical direction.

  The screw 56 is inserted into the insertion hole 63 of the dial 55 and is fastened and fixed to the attachment hole 38 of the case body 13 so that the dial 55 is rotatably attached to the case body 13.

  The rotating gear 57 includes a cylindrical shaft support portion 65 into which a screw 56 is inserted, and gear portions 66 and 67 (one and the other) projecting in a radial shape from the shaft support portion 65 in a fan shape. 55 and one (left side) side wall 27.

  The gear portions 66 and 67 protrude in different directions at positions shifted from each other in the axial direction of the shaft support portion 65. In the present embodiment, with the rotation gear 57 attached to the case body 13, the gear portion 66 protrudes toward the front upper side and meshes with the connecting gear 60, and the gear portion 67 protrudes toward the lower front side. And meshed with the driven gear 59. Further, the gear portion 67 is set to have a larger protruding amount from the shaft support portion 65 than the gear portion 66.

  The driven gears 58 and 59 are each formed in a fan shape, and square hole-shaped (one and the other) fixing holes 71 and 72 are opened at the position of the central axis. These fixing holes 71 and 72 project from one end (left end) in the longitudinal direction of the rotation shafts 47 and 48 of the fins 14 and 15 protruding outward from one (left) side wall 27. Further, prismatic fixing parts 74 and 75 are press-fitted. For this reason, the driven gears 58 and 59 are prevented from rotating with respect to the fins 14 and 15, and rotate (co-rotate) integrally with the fins 14 and 15 without idling.

  The connecting gear 60 has a round hole-shaped rotation shaft hole 81 opened at the center, and the mounting hole 38 is attached to one side wall 27 of the case body 13 (left side) with respect to the rotation shaft hole 81. By inserting a cylindrical shaft portion 82 projecting at a position on the front upper side, the shaft is pivotally supported with respect to the case body 13. The connection gear 60 includes (one and the other) meshing gear portions 84 and 85 on opposite sides of the rotation shaft hole 81, respectively. The meshing gear portion 84 is meshed with the gear portion 66 of the rotating gear 57, and the meshing gear portion 85 is meshed with the driven gear 58. As a result, the connecting gear 60 can change the rotation direction so that the driven gear 58 rotates in the same direction with respect to the rotation direction of the dial 55 (the rotation gear 57).

  The opening / closing means 16 rotates the dial 55 up and down to rotate the connection gear 60 and the driven gear 59 that are engaged with the gear portions 66 and 67 of the rotation gear 57 integrally with the dial 55. The driven gear 58 rotates in the direction opposite to the rotation direction of the gear 57 and the driven gear 58 meshed with the meshing gear portion 85 of the connecting gear 60 rotates in the same direction as the rotating gear 57. , 59 and fins 14, 15 so as to move up and down by interlocking with the anti-blowout outlet 41 side, that is, the rear end side, which is on the windward side of the rotating shaft portions 47, 48 of the fins 14, 15 connected integrally. Are rotated in opposite directions. In other words, the opening / closing means 16 can move the fins 14 and 15 in directions opposite to each other so that the rear end sides can be advanced and retracted simultaneously. That is, the fins 14 and 15 are opened and closed by the opening / closing means 16 when one of them advances from the recesses 33 and 34, the other also advances from the recesses 34 and 33, and when one of them retracts into the recesses 33 and 34, the other also enters the recesses 34 and 33. Evacuate.

  Specifically, the air distribution operation of the air outlet device 10 will be described.

  First, the state shown in FIG. 1 is a maximum retracted state of the fins 14 and 15 in which the fins 14 and 15 are fitted and accommodated in the recesses 33 and 34, and the rectifying surfaces 51 and 52 are the upper wall portion 25 and the lower wall. It is substantially flush with the surface of the wall 26 on the side of the ventilation path 32, and the steps in the recesses 33, 34 are almost filled with the fin bodies 45, 46 of the fins 14, 15. The cross-sectional area in the direction orthogonal to each other is substantially constant, and there is almost no pressure change inside the case body 13, and the wind introduced straight from the inlet 31 to the ventilation path 32 flows directly through the ventilation path 32. It goes straight in the axial direction and blows forward from the outlet 41 as a spot-like direct wind (neutral wind). In this state, the fins 14 and 15 are hidden behind the finisher 22 and the fins 14 and 15 are almost invisible from the air outlet 41, or the fins 14 and 15 and the inner surface of the case body 13 are flat. This makes it difficult to identify the fins 14 and 15 when viewed from the air outlet 41.

  Further, when the front portion of the dial 55 is rotated upward (clockwise in the figure) from the state shown in FIG. 1, as shown in FIG. And the gears 66 and 67 rotate in the same direction as the dial 55. At this time, the connecting gear 60 in which the meshing gear portion 84 is meshed with the gear portion 66 is configured so that the meshing gear portion 84 located on the rear side (leeward side) rotates relatively upward, The meshing gear portion 85 located on the (windward side) rotates relatively downward, and the driven gear 58 meshed with the meshing gear portion 85 faces downward (clockwise in the figure). By rotating, the upper fin 14 to which the driven gear 58 is integrally attached is centered on the rotation shaft portion 47, i.e., the front end side that is the air outlet 41 side, and the rear end side that is the counter air outlet 41 side is It turns downward. Further, the driven gear 59 meshed with the gear portion 67 of the rotating gear 57 rotates upward (counterclockwise direction in the drawing), so that the lower fin 15 to which the driven gear 59 is integrally attached. However, the rear end side, which is the anti-blowout port 41 side, rotates upward with the rotation shaft portion 48, that is, the front end side, which is the blowout port 41 side, as the center. Therefore, the rear end side that is the windward side of the fin bodies 45 and 46 of the fins 14 and 15 advances from the recesses 33 and 34 toward the center portion in the vertical direction that is the short direction of the ventilation path 32, and these fins 14 and 15 In contrast, the cross-sectional area in the direction orthogonal to the wind axis direction of the ventilation path 32 on the inflow side (windward side) is reduced (increase the ventilation resistance), and the rectifying surfaces 51 and 52 of the fins 14 and 15 are on the leeward side. It inclines in a widening manner to a certain front side. As a result, the wind introduced linearly from the inlet 31 to the ventilation path 32 is once squeezed by the fin bodies 45 and 46 of the fins 14 and 15 to increase the pressure, and then the fin bodies of these fins 14 and 15 The pressure suddenly decreases (opens) along the rectifying surfaces 51 and 52 that pass through the rear ends of 45 and 46 and expand toward the leeward side, and naturally becomes indirect wind (diffuse wind). 41 is blown forward.

  Then, when the front portion of the dial 55 is further rotated upward (clockwise in the drawing) from the state shown in FIG. 2 to bring the fins 14 and 15 into the maximum advanced state, the state shown in FIG. As shown in FIG. 3, the rear end side, which is the windward side of the fin bodies 45, 46 of the fins 14, 15, further advances to the vertical center part side, which is the short direction of the ventilation path 32, as shown in FIG. For example, the rear end portion of the lower fin 15 is brought into contact with the rectifying surface 51 of the upper fin 14, whereby the ventilation path 32 is closed over the entire longitudinal direction (left and right direction). For this reason, the wind linearly introduced from the inlet 31 to the ventilation path 32 is blocked (shut) by the fins 14 and 15 and cannot be blown forward from the outlet 41.

  When the front portion of the dial 55 is rotated downward (counterclockwise direction) from the state shown in FIGS. 3 and 2, the fins 14 and 15 are moved away from each other by the reverse operation. , 46 are rotated so as to be separated from each other, and are accommodated in the recesses 33, 34.

  As described above, according to the present embodiment, when the fins 14 and 15 paired by the opening and closing means 16 are interlocked and the counter-blowout outlet 41 side of these fins 14 and 15 is retracted with respect to the recesses 33 and 34, The fin bodies 45 and 46 are accommodated in the recesses 33 and 34 and are hidden in the positions of the long sides 41a and 41a facing each other of the air outlet 41 so that they are difficult to see from the air outlet 41. Thus, the pressure change hardly occurs, and the wind introduced from the inlet 31 to the ventilation path 32 blows out from the outlet 41 as direct wind. Further, when the fins 14 and 15 that are paired by the opening / closing means 16 are interlocked and the anti-blowout ports 41 of the fins 14 and 15 are advanced with respect to the recesses 33 and 34, the anti-blowout ports 41 of the fins 14 and 15 are provided. The air passage 32 becomes narrower at the position on the side and the wind pressure increases, and then the wind flows in an expanded manner along the fins 14 and 15 so that the pressure is released and the diffused air can be blown out from the outlet 41. it can. For this reason, it is possible to selectively blow out direct wind and indirect wind from the long air outlet 41 with a simple configuration without using many fins or complicated interlocking mechanisms, etc., and excellent air distribution performance The air outlet device 10 can be provided.

  In particular, in the long air outlet 41 of the thin air outlet device 10 that is considerably long in the longitudinal direction and short in the lateral direction, it is not easy to distribute the wind vertically and horizontally. By specializing in a configuration in which the wind is selectively switched between the direct wind and the indirect wind, an auxiliary utilization of a normal wind direction adjusting device is possible.

  Specifically, the analysis results of the wind direction and the air volume according to the present embodiment are schematically shown in FIGS. 7 (a) and 7 (b). As shown in FIGS. 7 (a) and 7 (b), it is understood that the direct air and the indirect air can be selectively and reliably blown out by the air outlet device 10 of the present embodiment.

  Further, since the ventilation path 32 can be closed by contacting the rear end sides of the fins 14 and 15, the fins 14 and 15 can function as a shut valve (enhance airtightness). Therefore, it is not necessary to provide a separate shut valve, the configuration of the outlet device 10 can be simplified, and the manufacturing cost can be reduced.

  Further, by configuring the opening / closing means 16 using a plurality of gears 57, 58, 59, 60, the fins 14, 15 are moved forward and backward with respect to the recesses 33, 34 in conjunction with the respective anti-blowout ports 41 side. The opening / closing means 16 for rotating in directions opposite to each other can be formed with an easy and simple configuration.

  In the above-described embodiment, the opening / closing means 16 is used if the advancement and retraction of the fins 14 and 15 on the counter-blowout outlet 41 side can be interlocked with each other to rotate the fins 14 and 15 in the opposite directions. The number and shape of the gears are not limited to the above configuration.

  Further, although the case body 13 has the left-right direction as the longitudinal direction, the longitudinal direction can be arbitrarily set according to the layout on the vehicle.

  The air outlet device 10 can be used not only as a part of the vehicle air conditioner but also as a part of an arbitrary air conditioner.

  The present invention can be applied, for example, as an air outlet of an air conditioner provided in an automobile instrument panel or the like.
