Description

  The present invention relates to a wind direction adjusting device having a passage portion provided with an outlet for blowing out wind.

  2. Description of the Related Art Conventionally, in an air conditioner used for a vehicle such as an automobile, a wind direction adjusting device provided at an outlet for blowing wind is also called an air conditioner air outlet, an air outlet, a ventilator, a register, etc., for example, an instrument panel or a center console unit For rear seat air conditioning installed in the vehicle, or for the second row (intermediate row) and third row (last row) of so-called minivan vehicles installed in overhead consoles, center pillars, door trims, etc. Things are known and contribute to the improvement of comfort performance by air conditioning.

  Although the opening size of the air outlet is related to the performance of the wind direction adjusting device, the degree of freedom in shape and size is limited by the relationship with the design of the vehicle.

  For example, in the case of an instrument panel, in order to install an audio device, a car navigation device, or the like, there is a case where a wide area is secured near a passenger and at a position where it can be easily viewed in consideration of the operability and visibility of the passenger. Although the wind blown from the air conditioning is preferably blown from an appropriate position for the occupant, in such a case, the selection range of the position and size may be limited depending on the relationship with the devices.

  As long as the wind direction adjusting device can secure a certain degree of operability for adjusting the wind direction, the dimensions may be small within the range where necessary performance can be obtained, but it is rather conservative in designing instrument panels. If it looks good, it can also enhance other illuminations and display devices, which not only improves the appearance of the instrument panel, but also makes various devices easy to see and operate.

  For example, in order to obtain the comfort after the second row of the minivan car, when the wind direction adjusting device is installed in the overhead console portion, the smaller the height of the air outlet, that is, the vertical dimension, the more forward the rear seat is. The field of view when viewing is widened, which is preferable for producing a sense of openness and refreshment.

  Then, as such a wind direction adjusting device, a pair of leeward inclined surfaces that are located at the upper and lower edges of the air outlet and incline in an expanding manner toward the downstream side, that is, the leeward side, and the upstream side of these leeward inclined surfaces, that is, the wind A pair of windward side inclined surfaces that are continuous to the upper side and incline in an expanding manner toward the windward side, and a small number of wind direction adjusting blades such as one, which are movably disposed near the center in the vertical direction of the air outlet, The structure which adjusts a wind direction with these inclined surfaces and a wind direction adjustment blade | wing is known (for example, refer patent document 1).

The connecting shaft 38 is sandwiched between the case body 22 and the spacers 16 and 16 and the main body 31 of the finisher 23, and the wind direction adjusting device 10 is completed.

  Next, the operation of the wind direction adjusting device 10 will be described.

  When the center fin 12 is in a neutral position, that is, in a neutral state, as shown in FIG. 1, the center fin body 37 of the center fin 12 is substantially horizontal (for example, a state inclined about 4 ° to the front lower side). At this time, the lower fin 13 is located at an intermediate position of the guide surface 28 in the front-rear direction. The blind 15 covers the upper part of the front end side of the lower bent portion 41b of the lower fin 13, the main guide surface 15e is substantially parallel to one rectifying surface 37a of the center fin body 37, and the sub guide surface 15f is Along the inclined surface 41d of the lower fin 13. Further, the upper fin 14 is located at an intermediate position of the guide surface 29 in the front-rear direction.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18, and below the center fin 12, one rectifying surface 37a of the center fin 12, the inclined surface 41d of the lower fin 13, and the blind The flow rate is reduced between the 15 sub guide surfaces 15f and the flow velocity is increased, along one of the straightening surfaces 37a and the main guide surface 15e of the blind 15, and above the center fin 12, the center fin 12 The flow rate is reduced between the other rectifying surface 37b and the inclined surface portion 44c of the upper fin 14 and the flow velocity is increased, and the flow velocity is increased along the other rectifying surface 37b and the inclined surface portion 44c. The wind direction is adjusted so as to blow out in a horizontal direction (for example, a direction inclined by about 4 ° on the front lower side) (FIG. 6A). In FIG. 6, the wind is indicated by an arrow, and the darker color tone is at a position where the wind speed is higher.

  For example, when the center fin 12 is rotated using the knob 20 so that the front portion on the downstream side is relatively downward (one direction), the plates 17 and 17 connected to the center fin 12 are centered. It rotates at the same angle in the same direction as the fin 12. Therefore, the lower fin 13 in which the slide shaft 42b is inserted into the working groove 68 of the plates 17 and 17 is gradually moved rearward according to the shape of the working groove 68, and the shape of the slide groove 56b, the slide pocket 56 and the lower Depending on the shape of the side slide portion 42, the shape of the guide rib 56a and the lower guided portion 41c, the shape of the guide surface 28, etc., the lower fin 13 extends rearward and upward along the guide surface 28, that is, the outlet 32. Advancing toward the center side, the inclined surface 41d is guided so as to approach the center side of the air outlet 32 and slides in an inclined shape. Further, the blind 15 slides on the lower slide portion 42 of the lower fin 13 so that the rear end side, that is, the lower fin 13 side gradually rises to the upper front side according to the shape of the cam groove 42c of the lower slide portion 42. The center fin body 37 rotates while maintaining a substantially parallel state. Further, the upper fin 14 in which the slide shaft portion 45b is inserted into the action groove 69 of the plates 17 and 17 is gradually moved forward according to the shape of the action groove 69, and the shape of the slide groove portion 57b, the slide pocket 57 and the upper side Depending on the shape of the slide portion 45, the shape of the guide rib portion 57a and the upper guided portion 44b, the shape of the guide surface 29, etc., the upper fin 14 moves forward and upward along the guide surface 29, that is, the outlet 32. Retracted from the center side so that the inclined surface portion 44c is separated from the center side of the air outlet 32, in other words, is guided to the second edge 32b side above the air outlet 32 and slides in an inclined shape. To do.

  As a result, in the state in which the center fin 12 is fully rotated downward, that is, in the maximum downward swing state, as shown in FIG. 2, the center fin body 37 of the center fin 12 is inclined to the front lower side by about 33 °, for example. The lower fin 13 is located at the position where it has advanced to the center of the air outlet 32 to the maximum, that is, at the rear end of the guide surface 28, and the blind 15 is slightly inclined forward and downward to the lower fin 13 Covers the upper part of the front end side of the lower bent portion 41b, the main guide surface 15e is along the inclined edge portion 32c of the outlet 32, the sub guide surface 15f is substantially parallel to the inclined surface 41d of the lower fin 13, and this inclined surface The upper fin 14 is located on substantially the same plane as 41d, and the upper fin 14 is retracted to the maximum with respect to the center side of the outlet 32, that is, in the vicinity of the second edge 32b on the front end of the guide surface 29 and on the upper side of the outlet 32 It is a hidden position on the back side of the main body 31, and the inclined surface 44c It is substantially parallel to the other of the rectifying surface 37b of the centers fin body 37.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18 and is centered along the inclined surface 41d of the lower fin 13 and the sub guide surface 15f of the blind 15 below the center fin 12. The flow is rectified to one rectifying surface 37a of the fin 12 and the flow rate is reduced between the one rectifying surface 37a and the main guide surface 15e of the blind 15 to increase the flow velocity. Along the guide surface 15e and above the center fin 12, the flow rate is reduced between the other rectifying surface 37b of the center fin 12 and the inclined surface portion 44c of the upper fin 14, and the flow rate is increased. The wind direction is adjusted along the rectifying surface 37b and the inclined surface portion 44c so as to blow out from the outlet 32 to the front lower side, for example, in a direction inclined by about 33 ° (FIG. 6B).

  Further, for example, when the center fin 12 is rotated using the knob 20 so that the front portion on the downstream side is relatively upward (in the other direction), the plates 17 and 17 connected to the center fin 12 are centered. It rotates at the same angle in the same direction as the fin 12. For this reason, the lower fin 13 in which the slide shaft 42b is inserted into the working groove 68 of the plates 17 and 17 is gradually moved forward according to the shape of the working groove 68, and the shape of the slide groove 56b, the slide pocket 56 and the lower Depending on the shape of the side slide portion 42, the shape of the guide rib 56a and the lower guided portion 41c, the shape of the guide surface 28, and the like, the lower fin 13 moves forward and downward along the guide surface 28, that is, the air outlet 32. So that the inclined surface 41d is separated from the center side of the outlet 32, in other words, is inclined to the second edge portion 32b on the lower side of the outlet 32. Slide to. Further, the blind 15 slides on the lower slide portion 42 of the lower fin 13 so that the rear end side, that is, the lower fin 13 side gradually descends to the lower rear side according to the shape of the cam groove 42c of the lower slide portion 42. In addition, it rotates while maintaining a state substantially parallel to the center fin body 37. Further, the upper fin 14 in which the slide shaft portion 45b is inserted into the action groove 69 of the plates 17 and 17 is gradually moved backward in accordance with the shape of the action groove 69, and the shape of the slide groove portion 57b, the slide pocket 57 and the upper side Depending on the shape of the slide portion 45, the shape of the guide rib portion 57a and the upper guided portion 44b, the shape of the guide surface 29, and the like, the upper fin 14 extends rearward and downward along the guide surface 29, that is, the air outlet 32. The inclined surface portion 44c is guided so as to approach the center side of the air outlet 32 and slides in an inclined shape.

  As a result, in the state in which the center fin 12 is fully rotated upward, that is, in the maximum upward swing state, as shown in FIG. 3, the center fin body 37 of the center fin 12 is inclined upward by, for example, about 27 °. The lower fin 13 is located at the maximum retracted position with respect to the center side of the air outlet 32, that is, at the front end of the guide surface 28 and on the back side of the main body 31 near the second edge 32b on the lower side of the air outlet 32. The blind 15 is in a hidden position, and is inclined so as to be substantially parallel to the center fin body 37 of the center fin 12 toward the rear upper side, covering the upper part of the lower bent portion 41b of the lower fin 13 and the rear guide The portion 15b is located at a step between the lower bent portion 41b and the lower inclined portion 41a of the lower fin 13, and the main guide surface 15e is substantially parallel to the one rectifying surface 37a of the center fin body 37 and the inclined surface 41d of the lower fin 13. And this inclined surface 41d and almost Located on one side, the upper fin 14, position protruding to the maximum to the center side of the air outlet 32, that is, at the rear end of the guide surface 29.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18, and below the center fin 12, one rectifying surface 37a of the center fin 12, the inclined surface 41d of the lower fin 13, and the blind The flow rate is reduced between the 15 main guide surfaces 15e and the flow velocity is increased, and the flow velocity is increased along the one straightening surface 37a, the inclined surface 41d, and the main guide surface 15e. 14 is rectified to the other rectifying surface 37b of the center fin 12 along the inclined surface portion 44c, and the flow rate is reduced between the other rectifying surface 37b and the inclined surface portion 44c to increase the flow velocity. The wind direction is adjusted along the rectifying surface 37b and the inclined surface portion 44c so as to blow out from the air outlet 32 to the rear upper side, for example, in a direction inclined by about 27 ° (FIG. 6C).

  Thus, according to the present embodiment, the lower fin 13 disposed on the second edge portion 32b on the lower side of the air outlet 32 is located on the center side of the air outlet 32 in response to the rotation of the center fin 12. On the other hand, the inclined surface 41d advances and retreats so that it approaches or separates, so that the center fin 12 advances and retreats toward the center of the outlet 32 of the lower fin 13 regardless of the downward or upward direction. Due to the approach or separation of the inclined surface 41d, the wind distribution performance can be secured and the wind axis angle equivalent to the rotation angle (swing angle) of the center fin 12 can be directed.

  Further, at the position where the inclined surface 41d of the lower fin 13 is separated from the center side of the air outlet 32, the lower fin 13 is hardly seen from the air outlet 32 side, and the appearance can be improved.

  Further, the lower fin 13 advances and retreats with respect to the center side of the air outlet 32 in response to the rotation of the center fin 12 and covers the space between the lower fin 13 and the second edge 32b below the air outlet 32. 15 rotates (moves) so that the main guide surface 15e follows the center fin 12 in response to the advancement and retraction of the lower fin 13 accompanying the rotation of the center fin 12, so that the center fin 12 is moved downward and upward. Regardless of the direction of rotation, the air distribution performance can be further improved by moving the lower fin 13 toward and away from the center of the air outlet 32 and rotating (moving) the blind 15. In particular, when the lower fin 13 advances to the center side of the air outlet 32, the auxiliary guide surface 15f of the blind 15 is along the inclined surface 41d of the lower fin 13, and the main guide surface 15e continuous with the auxiliary guide surface 15f is the center fin 12. Since it is along one rectifying surface 37a, wind can be smoothly guided from the inclined surface 41d of the lower fin 13 to the outlet 32, and the occurrence of air vortices at the front end of the inclined surface 41d can be suppressed, and the air distribution performance Can be further improved (FIGS. 6A to 6C).

  Further, since the lower fin 13 is covered with the blind 15 on the blowout port 32 side, the lower fin 13 including the inclined surface 41d inclined toward the upstream side of the wind passing through the passage portion 11 is directed downward in the center fin 12. Even if it advances to the center side of the air outlet 32 corresponding to the rotation, the back side of the lower fin 13 is not exposed to the air outlet 32 side, and the appearance can be improved. In particular, since a general occupant has a viewpoint at an upper position with respect to the wind direction adjusting device 10, the lower side of the air outlet 32 can be easily seen, so the lower fin 13 positioned below the air outlet 32 is blinded. Since it is covered with 15 and the back side of the lower fin 13 is not exposed to the air outlet 32 side, appearance can be secured. Note that when the wind direction adjusting device 10 is mounted at an upper (high) position relative to an occupant such as an overhead console, for example, the occupant has a viewpoint at a lower position with respect to the wind direction adjusting device 10, so Since the upper side inside the outlet 32 can be easily seen, it is needless to say that the same effect can be obtained by arranging the blind 15 on the upper fin 14 side. That is, depending on the vertical positional relationship between the occupant and the wind direction adjusting device 10, it is possible to arbitrarily set whether the blind 15 is disposed on the lower fin 13 side or the upper fin 14 side.

  Further, the second fin 32b on the upper side of the air outlet 32, that is, the upper fin 14 located on the opposite side of the lower fin 13 with respect to the center fin 12 (and the central part of the air outlet 32) is passed through the passage portion 11. The upper fin 14 is inclined in the direction opposite to the lower fin 13 with respect to the center side of the air outlet 32 in conjunction with the rotation of the center fin 12. The slanted surface 41d of the lower fin 13 and the slanted surface portion 44c of the upper fin 14 are close to the center side of the air outlet 32 and the other is the air outlet. Since these are separated from the center side of 32, the lower fin 13, the upper fin 14 and the blind 15 are directed to the wind axis angle equivalent to the rotation angle of the center fin 12 regardless of the rotation direction of the center fin 12. Door can be, air distribution performance can be further improved.

  Therefore, the lower fin 13 and the upper fin 14 move to the optimum positions corresponding to the rotation angle (swing angle) of the center fin 12, and can be directed to correspond to any rotation angle (swing angle) of the center fin 12. A simple wind direction adjusting device 10 can be provided.

  When the center fin 12 is rotated, the plates 17 and 17 are rotated integrally with the center fin 12 to move the lower fin 13, and the moving direction of the lower fin 13 is changed by the spacers 16 and 16 at the outlet 32. The cam groove 42c provided in the lower fin 13 rotates the blind 15 so that the main guide surface 15e of the blind 15 follows the wind direction at the center fin 12 by being guided in the direction of moving forward and backward with respect to the center side. The structure in which the blind 15 rotates (moves) so that the main guide surface 15e follows the center fin 12 in response to the advancement and retraction of the lower fin 13 interlocked with the rotation of the center fin 12 can be easily formed.

  Furthermore, the lower fin 13, the upper fin 81, the blind 15, and the upper blind 82 are connected to the other spacer 16 as in the case of the one spacer 16.

  The integrated spacers 16 and 16, the lower fin 13, the upper fin 81, the blind 15 and the upper blind 82 are connected to the slide shaft 42b and the insertion guide 53 from the opening 26 of the case body 22 to which the rear fin 18 is attached. The slide shaft portion 85b and the insertion guide 54 are aligned with respect to the insertion groove 52, and are then inserted and assembled rearward. In this state, the slide groove 56b, the slide groove portion 57b, and the bearing concave portion 59 of each spacer 16 are aligned with the groove portion 61, the groove portion 63, and the U-shaped groove portion 65 of the case body 22, respectively, and are removed from the slide groove 56b and the slide groove portion 57b. The slide shaft 42b and the slide shaft portion 85b that protrude in the direction protrude from the groove portion 61 and the groove portion 63 toward the outer side of the case body 22, respectively.

  Thereafter, similarly to the first embodiment, the shaft portions 38a of the connection shafts 38 of the center fin 12 to which the knob 20 is previously attached are temporarily placed in the bearing recess 59 and the U-shaped groove portion 65, and the case body 22 is placed. Each plate 17 is attached from the outside of the plate so that each insertion hole 67 is fitted to each connection convex portion 38b, and the finisher 23 is assembled to the case body 22, whereby the wind direction adjusting device 10 is completed.

  When the center fin 12 is in the neutral position, that is, in the neutral state, as shown in FIG. 7, the center fin body 37 of the center fin 12 is substantially horizontal (for example, a state inclined about 3 ° to the rear lower side). . At this time, the lower fin 13 is located at an intermediate position of the guide surface 28 in the front-rear direction. The blind 15 covers the upper portion of the lower bent portion 41b of the lower fin 13 on the rear end side, the main guide surface 15e is substantially parallel to the one rectifying surface 37a of the center fin body 37, and the sub guide surface 15f. Is along the inclined surface 41d of the lower fin 13. Further, the upper fin 81 is located at an intermediate position of the guide surface 29 in the front-rear direction. The upper blind 82 covers the lower portion of the upper inclined portion 84a of the upper fin 81, and the main guide surface portion 82e is substantially parallel to the other rectifying surface 37b of the center fin body 37.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18, and below the center fin 12, one rectifying surface 37a of the center fin 12, the inclined surface 41d of the lower fin 13, and the blind The flow rate is reduced between the 15 sub guide surfaces 15f and the flow velocity is increased, along one of the straightening surfaces 37a and the main guide surface 15e of the blind 15, and above the center fin 12, the center fin 12 The flow rate is reduced between the other rectifying surface 37b and the main guide surface portion 82e of the upper blind 82, and the flow velocity is increased, along the other rectifying surface 37b and the main guide surface portion 82e, and backward from the outlet 32. The wind direction is adjusted so as to blow out in a substantially horizontal direction (for example, a direction inclined about 3 ° rearward and lower) (FIG. 11A). In FIG. 11, the wind is indicated by an arrow, and the darker color tone is at a position where the wind speed is higher.

  Further, for example, when the center fin 12 is rotated using the knob 20 so that the rear portion on the downstream side is relatively directed downward (one direction), the plates 17 and 17 connected to the center fin 12 are connected to the center fin 12. It rotates in the same direction as 12. Therefore, the lower fin 13 in which the slide shaft 42b is inserted into the working groove 68 of the plates 17 and 17 is gradually moved rearward according to the shape of the working groove 68, and the shape of the slide groove 56b, the slide pocket 56 and the lower Depending on the shape of the side slide portion 42, the shape of the guide rib 56a and the lower guided portion 41c, the shape of the guide surface 28, etc., the lower fin 13 extends rearward and upward along the guide surface 28, that is, the outlet 32. It is guided to advance toward the center side and slides in an inclined shape. Further, the blind 15 slides on the lower slide portion 42 of the lower fin 13 so that the rear end side, that is, the lower fin 13 side gradually rises to the upper front side according to the shape of the cam groove 42c of the lower slide portion 42. The center fin body 37 rotates while maintaining a substantially parallel state. Further, the upper fin 81 in which the slide shaft portion 85b is inserted into the action groove 69 of the plates 17 and 17 is gradually moved forward in accordance with the shape of the action groove 69, and the shape of the slide groove portion 57b, the slide pocket 57 and the upper side Depending on the shape of the slide portion 85, the shape of the guide rib portion 57a and the upper guided portion 84b, the shape of the guide surface 29, etc., the upper fin 81 is moved forward and upward along the guide surface 29, that is, the outlet 32. In other words, it is guided to slide toward the second edge 32b on the upper side of the air outlet 32 so as to retreat with respect to the center side. Further, when the upper blind 82 slides on the upper slide portion 85 of the upper fin 81, the rear end side, that is, the upper fin 81 side gradually rises to the front upper side according to the shape of the cam groove 85c of the upper slide portion 85. In addition, it rotates while maintaining a state substantially parallel to the center fin body 37.

  As a result, in the state in which the center fin 12 is fully rotated downward, that is, in the maximum downward state, as shown in FIG. 8, the center fin body 37 of the center fin 12 is tilted to the front lower side by about 31 °, for example. The lower fin 13 is located at the position where it has advanced to the center of the air outlet 32 to the maximum, that is, at the rear end of the guide surface 28, and the blind 15 is slightly inclined forward and downward to the lower fin 13 Covers the upper part of the front end side of the lower bent portion 41b, the main guide surface 15e is along the inclined edge portion 32c of the outlet 32, the sub guide surface 15f is substantially parallel to the inclined surface 41d of the lower fin 13, and this inclined surface The upper fin 81 is located almost on the same plane as 41d, and the upper fin 81 is retracted to the maximum with respect to the center side of the outlet 32, that is, near the second edge 32b on the front end of the guide surface 29 and on the upper side of the outlet 32. The upper bra Command 82 covers the lower portion of the upper inclined portion 84a of the upper fin 81 is inclined to the front lower side, the main guide surface portion 82e is substantially parallel with the other of the rectifying surface 37b of the center fin body 37.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18 and is centered along the inclined surface 41d of the lower fin 13 and the sub guide surface 15f of the blind 15 below the center fin 12. The flow is rectified to one rectifying surface 37a of the fin 12 and the flow rate is reduced between the one rectifying surface 37a and the main guide surface 15e of the blind 15 to increase the flow velocity. Along the guide surface 15e and above the center fin 12, in the state where the flow rate is reduced between the other rectifying surface 37b of the center fin 12 and the main guide surface portion 82e of the upper blind 82, the flow velocity is increased. The wind direction is adjusted along the straightening surface 37b and the main guide surface portion 82e so as to blow out from the air outlet 32 to the front lower side, for example, in a direction inclined about 31 ° (FIG. 11B).

  Further, for example, when the center fin 12 is rotated using the knob 20 so that the front portion on the downstream side is relatively upward (in the other direction), the plates 17 and 17 connected to the center fin 12 are centered. It rotates at the same angle in the same direction as the fin 12. For this reason, the lower fin 13 in which the slide shaft 42b is inserted into the working groove 68 of the plates 17 and 17 is gradually moved forward according to the shape of the working groove 68, and the shape of the slide groove 56b, the slide pocket 56 and the lower Depending on the shape of the side slide portion 42, the shape of the guide rib 56a and the lower guided portion 41c, the shape of the guide surface 28, and the like, the lower fin 13 moves forward and downward along the guide surface 28, that is, the air outlet 32. In other words, it is guided to slide toward the second edge 32b on the lower side of the air outlet 32 so as to retreat with respect to the center side. Further, the blind 15 slides on the lower slide portion 42 of the lower fin 13 so that the rear end side, that is, the lower fin 13 side gradually descends to the lower rear side according to the shape of the cam groove 42c of the lower slide portion 42. In addition, it rotates while maintaining a state substantially parallel to the center fin body 37. Further, the upper fin 81 in which the slide shaft portion 45b is inserted into the action groove 69 of the plates 17 and 17 is gradually moved backward in accordance with the shape of the action groove 69, and the shape of the slide groove portion 57b, the slide pocket 57 and the upper side Depending on the shape of the slide portion 85, the shape of the guide rib portion 57a and the upper guided portion 84b, the shape of the guide surface 29, and the like, the upper fin 81 extends rearward and downward along the guide surface 29, that is, the air outlet 32. It is guided to advance to the center side of and slides in an inclined shape. Further, when the upper blind 82 slides on the upper slide portion 85 of the upper fin 81, the rear end side, that is, the upper fin 81 side gradually descends to the rear lower side according to the shape of the cam groove 85c of the upper slide portion 85. As described above, the center fin body 37 rotates while maintaining a substantially parallel state.

  As a result, in the state in which the center fin 12 is fully rotated upward, that is, in the maximum swing-up state, as shown in FIG. 9, the center fin body 37 of the center fin 12 is inclined forward by about 26 °, for example. The lower fin 13 is located at the maximum retracted position with respect to the center side of the air outlet 32, that is, at the front end of the guide surface 28 and on the back side of the main body 31 near the second edge 32b on the lower side of the air outlet 32. In the hidden position, the blind 15 is inclined so as to be substantially parallel to the center fin main body 37 of the center fin 12 and covers the upper part of the lower bent portion 41b of the lower fin 13 and guides the rear side. The portion 15b is located at a step between the lower bent portion 41b and the lower inclined portion 41a of the lower fin 13, and the main guide surface 15e is substantially parallel to the inclined surface 41d of the lower fin 13 and is substantially flush with the inclined surface 41d. Located on the upper fin 81, blow The upper blind 82 is located at a position that protrudes to the center side of the mouth 32, that is, at the rear end of the guide surface 29, and the upper blind 82 is inclined to be substantially parallel to the center fin body 37 of the center fin 12 toward the upper front side. Cover the lower portion on the front end side of the upper inclined portion 84a of the upper fin 81, the main guide surface portion 82e is parallel to the other rectifying surface 37b of the center fin body 37, and the sub guide surface portion 82f is below the inclined surface portion 84c of the upper fin 81. And along the inclined surface portion 84c.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18, and below the center fin 12, one rectifying surface 37a of the center fin 12, the inclined surface 41d of the lower fin 13, and the blind The flow rate is reduced between the 15 main guide surfaces 15e and the flow velocity is increased, and the flow velocity is increased along the one straightening surface 37a, the inclined surface 41d, and the main guide surface 15e. 81 is rectified along the inclined surface portion 84c of the 81 and the auxiliary guide surface portion 82f of the upper blind 82 to the other rectifying surface 37b of the center fin 12, and between the other rectifying surface 37b and the main guide surface portion 82e of the upper blind 82. In a state where the flow rate is reduced and the flow velocity is increased, the airflow direction is adjusted so that the airflow is blown out along the other rectifying surface 37b and the main guide surface portion 82e from the air outlet 32 in a direction inclined, for example, by about 26 °. FIG. )).

  Thus, according to the second embodiment, the upper fin 81 arranged on the second edge 32b side above the air outlet 32 is opposite to the lower fin 13 in response to the rotation of the center fin 12. The upper blind 82 covering the space between the upper fin 81 and the second edge 32b on the upper side of the air outlet 32 is advanced and retracted so that the inclined surface portion 84c is separated from or approached to the center side of the air outlet 32. Corresponding to the advance and retreat of the upper fin 81 interlocked with the rotation of the fin 12, the center fin 12 is rotated (moved) along the center fin 12 so that the center fin 12 can be moved downward or upward. Even if it is rotated in this direction, air distribution performance is ensured by moving the lower fin 13 and the upper fin 81 back and forth in the opposite direction to the center of the outlet 32 and rotating (moving) the blind 15 and the upper blind 82. Can, center The wind axis angle equivalent to the rotation angle (swing angle) of the fin 12 can be directed. In particular, when the lower fin 13 advances to the center side of the air outlet 32, the auxiliary guide surface 15f of the blind 15 is along the inclined surface 41d of the lower fin 13, and the main guide surface 15e continuous with the auxiliary guide surface 15f is the center fin 12. Since the air flows along the one rectifying surface 37a, the wind can be smoothly guided from the inclined surface 41d of the lower fin 13 to the outlet 32, and airflow vortices can be prevented from being generated at the front end of the inclined surface 41d, and the upper fin When 81 advances to the center side of the air outlet 32, the auxiliary guide surface portion 82f of the upper blind 82 is along the inclined surface portion 84c of the upper fin 81, and the main guide surface portion 82e continuous with the auxiliary guide surface portion 82f is the other side of the center fin 12. Therefore, the air can be smoothly guided from the inclined surface portion 84c of the upper fin 81 to the air outlet 32, and air flow vortices can be prevented from being generated at the front end portion of the inclined surface portion 84c. Can be further improved (FIG. 11 (a)) FIG. 11 (c)).

  Further, since the space between the upper fin 81 and the second edge portion 32b on the upper side of the air outlet 32 is covered by the upper blind 82, the inclined surface portion 84c inclined toward the upstream side of the wind passing through the passage portion 11 is provided. Even if the provided upper fin 81 advances toward the center side of the air outlet 32 in response to the upward rotation of the center fin 12, the back side of the upper fin 81 is not exposed to the air outlet 32 side. Therefore, the appearance of the blind 15 and the upper blind 82 can be further improved regardless of the rotation angle of the center fin 12.

  Further, when the center fin 12 is rotated, the plates 17 and 17 are rotated integrally with the center fin 12 to move the lower fin 13 and the upper fin 81, and the moving direction of the lower fin 13 and the upper fin 81 is the spacer. The cam groove 42c provided in the lower fin 13 and the cam groove 85c provided in the upper fin 81 are guided by the main guide surface 15e of the blind 15 by being guided in the direction of advancing and retreating with respect to the center side of the air outlet 32 by 16, 16. In order to rotate the blind 15 and the upper blind 82 so that the main guide surface portion 82e of the upper blind 82 follows the wind direction at the center fin 12, the lower fin 13 and the upper fin 81 interlocked with the rotation of the center fin 12 Correspondingly, the blind 15 and the upper blind 82 are rotated (moved) so that the main guide surface 15e and the main guide surface portion 82e are along the center fin 12. ) Configurations may easily formed to.

  Next, a third embodiment will be described with reference to FIGS. In addition, about the structure and effect | action similar to said each embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In the third embodiment, instead of the lower fin 13 of the first and second embodiments, as shown in FIGS. 12 to 14, a lower fin 91 as a deflection blade is rotatably arranged. In addition, instead of the upper fins 14 and 81 of the first and second embodiments, an upper fin 92 as a deflection blade portion is rotatably arranged.

  The lower fin 91 is formed in a long plate shape in the left-right direction, and is spaced behind the second edge 32b on the lower side of the air outlet 32 in the case body 22 (in the air passage 24). And in front of the rear fin 18.

  The lower fin 91 is a lower inclined portion 91a as an inclined portion (one) inclined downward toward the rear side, and a (one) flat plate portion continuous to the rear end portion of the lower inclined portion 91a. And a lower flat plate portion 91b.

  The upper surface of the lower inclined portion 91a is an inclined surface 91c inclined downward toward the upstream side, that is, the rear side of the wind passing through the air passage 24 in the case body 22, and the wind passing through the air passage 24 is forward It is comprised so that it may guide to an upper side.

  The lower flat plate portion 91b is formed in a flat plate shape and is continuous in a bent shape with respect to the lower inclined portion 91a. Further, the lower flat plate portion 91b is pivotally supported on both sides of the case body 22 on the left and right sides. Therefore, the lower fin 91 moves in the vertical direction on the lower inclined portion 91a (inclined surface 91c) as it rotates, and approaches or separates (advances / retreats) with respect to the center side of the air outlet 32. .

  Similarly, the upper fin 92 is formed in an elongated plate shape in the left-right direction, and is located behind the second edge 32b on the upper side of the air outlet 32 in the case body 22 (in the air passage 24). It is arranged at a spaced position and in front of the rear fin 18.

  The upper fin 92 is an upper inclined portion 92a that is inclined toward the upper rear side (the other) as an inclined portion, and a (other) flat plate portion that is continuous with the rear end portion of the upper inclined portion 92a. The upper flat plate portion 92b is integrally provided.

  The lower surface of the upper inclined portion 92a is an inclined surface portion 92c inclined toward the upstream side of the wind passing through the air passage 24 in the passage portion 11, and guides the wind passing through the air passage 24 to the front lower side. Is configured to do.

  The upper flat plate portion 92b is formed in a flat plate shape and is continuous in a bent shape with respect to the upper inclined portion 92a. The upper flat plate portion 92b is pivotally supported on both sides of the case body 22 on both the left and right sides. For this reason, the upper fin 92 moves in the vertical direction on the upper inclined portion 92a (inclined surface portion 92c) as it rotates, and approaches or separates (advances / retreats) with respect to the center side of the air outlet 32. .

  The lower fin 91 and the upper fin 92 are connected to the center fin 12 via a plate as a cam (not shown) that rotates integrally with the center fin 12, respectively. It is configured to rotate in conjunction with each other.

  In addition, a spacer 94 is disposed inside the case body 22 so as to face the opening 26, that is, adjacent to the rear portion of the finisher 23. The spacer 94 is attached to the case body 22 with the front end portion being in close contact with the back side of the main body 31 of the finisher 23. In addition, the spacer 94 includes a plurality of lower rectification portions 94a as rectification portions (one) that are inclined toward the lower rear side continuously from the rear portion of the second edge portion 32b on the lower side of the air outlet 32. In addition, a plurality of upper rectification units 94b as rectification units (in other words) that are inclined toward the rear upper side are provided continuously to the rear part of the second edge 32b on the upper side of the air outlet 32.

  The lower rectification unit 94a is disposed at substantially equal intervals in the left-right direction of the air outlet 32, and is continuous with the inclined edge portion 32c of the air outlet 32 in a bent shape. In addition, a lower notch fitting portion 94c serving as a notch fitting portion (one) is fitted to the front end side of the lower inclined portion 91a of the lower fin 91 on the upper portion of the rear portion of each lower rectifying portion 94a. Is cut out.

  The upper rectification unit 94b is disposed at substantially equal intervals in the left-right direction of the air outlet 32, and is continuous with the second edge 32b on the upper side of the air outlet 32 in a bent shape. In addition, an upper notch fitting portion 94d as a notch fitting portion (the other notch fitting portion) that fits the front end side that is the tip side of the upper inclined portion 92a of the upper fin 92 is cut off at the lower part of the rear portion of each upper rectifying portion 94b. It is not formed.

  When the center fin 12 is in the neutral position, that is, in the neutral state, the center fin body 37 of the center fin 12 is substantially horizontal. At this time, in the lower fin 91, the lower flat plate portion 91b is slightly separated upward from the lower surface in the case body 22, and the tip portion of the lower inclined portion 91a is substantially the same as the second edge portion 32b below the outlet 32. Located on the same plane. Similarly, in the upper fin 92, the upper flat plate portion 92b is slightly spaced downward from the upper surface in the case body 22, and the tip of the upper inclined portion 92a is substantially flush with the second edge portion 32b on the upper side of the outlet 32. Located on top (FIG. 12). Therefore, the lower fin 91 and the upper fin 92 are difficult to see from the front direction of the center fin 12, that is, the direction parallel to the rectifying surfaces 37a and 37b.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18, and on the lower side of the center fin 12, the tip side of the lower inclined portion 91a of the lower fin 91 is one rectification of the center fin 12. Opposing the surface 37a, the flow rate is reduced between the one rectifying surface 37a and the inclined surface 91c of the lower fin 91 and the flow velocity is increased along the one rectifying surface 37a, above the center fin 12, The flow rate is reduced between the other rectifying surface 37b of the center fin 12 and the inclined surface portion 92c of the upper fin 92, and the flow velocity is increased. The wind direction is adjusted to blow out in the direction.

  Further, for example, when the center fin 12 is rotated using the knob 20 so that the front portion on the downstream side is relatively directed downward (one direction), the lower fin 91 is gradually rotated upward by the link mechanism. Then, the inclined surface 91c approaches the center side of the air outlet 32, and the upper fin 92 is gradually rotated upward, and the inclined surface portion 92c is separated from the center side of the air outlet 32 and is inclined upward. The portion 92a is fitted into the upper notch fitting portion 94d, and the upper flat plate portion 92b is in contact with the upper surface of the case body 22 (FIG. 13).

  As a result, in the state in which the center fin 12 is fully rotated downward, that is, in the maximum downward swing state, the center fin body 37 of the center fin 12 is inclined forward and downward, and the lower fin 91 is connected to the air outlet 32. The inclined surface 91c is located at the position closest to the center, and the upper fin 92 is located at the position where the inclined surface portion 92c is separated from the center of the outlet 32 to the maximum, and the inclined surface portion 92c is located with respect to the upper rectifying portion 94b. And are almost flush with each other. In this state, the tip side of the lower inclined portion 91a of the lower fin 91 is located slightly above the second edge portion 32b on the lower side of the air outlet 32, but the front direction of the center fin 12, that is, the center fin 12 When viewed from a direction parallel to the straightening surfaces 37a and 37b, the tip end side of the lower inclined portion 91a of the lower fin 91 is substantially flush with the inclined edge portion 32c, and the upper fin 92 is connected to the outlet 32. Is hidden behind the main body 31 of the finisher 23 above the second edge 32b on the upper side. Therefore, the lower fin 91 and the upper fin 92 are difficult to see from the front direction of the center fin 12.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18, and below the center fin 12, on one side of the rectification surface 37a of the center fin 12 along the inclined surface 91c of the lower fin 91. The flow rate is reduced between the one rectifying surface 37a and the inclined surface 91c of the lower fin 91 and the flow velocity is increased, and the flow velocity is increased along the one rectifying surface 37a. On the upper side, the tip side of the upper inclined portion 92a of the upper fin 92 faces the other rectifying surface 37b of the center fin 12, and between the other rectifying surface 37b and the inclined surface portion 92c of the upper fin 92 and the upper rectifying portion 94b. In a state where the flow rate is reduced and the flow velocity is increased, the wind direction is adjusted so as to blow out in a direction inclined downward from the outlet 32 along the other rectifying surface 37b, the inclined surface portion 92c, and the upper rectifying portion 94b.

  Further, for example, when the center fin 12 is rotated using the knob 20 so that the front portion on the downstream side is relatively upward (in the other direction), the lower fin 91 is gradually rotated downward by the link mechanism. The inclined surface 91c is separated from the center side of the air outlet 32 so that the lower inclined portion 91a is fitted into the lower notch fitting portion 94c and the lower flat plate portion 91b is brought into contact with the lower surface of the case body 22. Then, the upper fin 92 gradually turns downward, and the inclined surface portion 92c approaches the center side of the air outlet 32 (FIG. 14).

  As a result, in the state in which the center fin 12 is fully rotated upward, that is, in the maximum upward swing state, the center fin body 37 of the center fin 12 is inclined forward and upward, and the lower fin 91 is located at the center of the air outlet 32. The inclined surface 91c is located at the maximum distance from the side, the inclined surface 91c is substantially flush with the lower rectifying portion 94a, and the upper fin 92 is maximized toward the center side of the air outlet 32. It becomes the protruding position. In this state, the lower fin 91 is hidden on the back side of the main body 31 of the finisher 23 below the second edge 32b on the lower side of the air outlet 32, and the tip side of the upper inclined portion 92a of the upper fin 92 is Although located slightly below the second edge 32b on the upper side of the air outlet 32, when viewed from the front direction of the center fin 12, that is, from the direction parallel to the straightening surfaces 37a and 37b of the center fin 12, the upper The tip end side of the upper inclined portion 92a of the fin 92 is substantially flush with the upper second edge portion 32b. Therefore, the lower fin 91 and the upper fin 92 are difficult to see from the front direction of the center fin 12, that is, the direction parallel to the rectifying surfaces 37a and 37b.

  The wind flowing into the air passage 24 from the introduction port 25 is rectified by the rear fin 18, and below the center fin 12, one rectifying surface 37a of the center fin 12, the inclined surface 91c of the lower fin 91, and the lower The upper fin 92 is located above the center fin 12 along the one rectifying surface 37a, the inclined surface 91c, and the lower rectifying portion 94a in a state where the flow rate is reduced and the flow velocity is increased with the side rectifying portion 94a. In the state where the flow rate is reduced and the flow velocity is increased between the other rectifying surface 37b and the inclined surface portion 92c, being collected and rectified along the inclined surface portion 92c toward the other rectifying surface 37b of the center fin 12. The air direction is adjusted so that the air flows along the other rectifying surface 37b and the inclined surface portion 92c in a direction inclined rearward and upward from the air outlet 32.

  As described above, according to the third embodiment, the lower fin 91 disposed on the second edge portion 32b on the lower side of the air outlet 32 corresponds to the rotation of the center fin 12 and the center of the air outlet 32. If the center fin 12 is rotated in either the downward direction or the upward direction by rotating so that the inclined surface 91c approaches or separates from the side, the center side of the outlet 32 of the lower fin 91 With the approach or separation of the inclined surface 91c accompanying the advance or retreat, the air distribution performance can be ensured and the air can be directed to the wind axis angle equivalent to the rotation angle (swing angle) of the center fin 12, etc. Effects similar to those of the embodiment can be achieved with a simpler configuration.

  Further, in a state where the inclined surface 91c of the lower fin 91 is rotated to a position separated from the center side of the blower outlet 32, the lower fin 91 is hardly seen from the blower outlet 32 side, and the appearance can be further improved.

  Further, the upper fin 92 disposed on the second edge portion 32b on the upper side of the air outlet 32 is inclined with respect to the center side of the air outlet 32 in the opposite direction to the lower fin 91 in response to the rotation of the center fin 12. Even if the center fin 12 is rotated upward and downward by rotating so that the 92c approaches or separates, the lower fins 91 and the upper fins 92 are opposite to each other toward the center of the outlet 32. The air distribution performance can be further improved by the rotation, and the upper fin 92 is not easily seen from the air outlet 32 side when the inclined surface portion 92c of the upper fin 92 is retracted so as to be separated from the center side of the air outlet 32. , Can improve the appearance.

  Moreover, regardless of the position of the center fin 12, only the center fin 12 can be seen from the front direction of the center fin 12, so that the appearance is very good.

  Since the wind direction adjusting device 10 that can be directed corresponding to an arbitrary rotation angle (swing angle) of the center fin 12 can be simply configured by only the lower fin 91 and the upper fin 92, the passage portion 11 (the case body 22) Space), the length ratio between the vertical direction and the horizontal direction of the air outlet 32, that is, the aspect ratio is increased. In other words, the vertical length is It is possible to provide a wind direction adjusting device 10 having sufficient directivity while having a slim shape with a short direction. Therefore, it is possible to widen the selection range of the layout of an automobile or the like in which the wind direction adjusting device 10 is arranged.

  In each of the above embodiments, the center fin 12 is configured to be manually rotated using the knob 20, but for example, by providing a gear portion on the plate 17 and meshing with driving means such as a motor, The rotation of the center fin 12 may be automatically controlled via the plate 17.

  Moreover, the blower outlet 32 can be made into arbitrary shapes provided with the 2nd edge part which mutually opposes, such as elliptical shape, for example.

  Furthermore, the wind direction adjusting device 10 is not limited to the vehicle, and can be used for adjusting the wind direction of an arbitrary air conditioner or the like.

  The present invention can be suitably used, for example, as a wind direction adjusting device for air conditioning of automobiles.
