Description

  The present invention relates to a wind direction adjusting device, for example, a wind direction adjusting device provided in an air blowing portion of a vehicle. In the present invention, the meanings of the rotating shaft and the rotating shaft include the meaning as the shaft portion of the shaft and the meaning as the axis of the shaft.

  A vehicle wind direction adjusting device is mounted on an instrument panel of a vehicle, for example, and includes a hollow case body connected to a duct that supplies temperature-controlled and air volume adjusted air, and an air blower for the case body. And a blade for controlling the air distribution direction of the adjustment air blown from the outlet.

  In general, as a blade for controlling the distribution direction of the adjustment air, for example, one or more front blades that distribute the adjustment air in the vertical direction or the left-right direction are provided on the opening side of the air outlet. Configuration is adopted. In the configuration in which a plurality of front blades are provided, each front blade is configured to be able to rotate in conjunction with each other.

  Then, a configuration is adopted in which the rear blades that distribute the adjustment air in the left-right direction or the up-down direction, which are different from the air distribution direction of the front blades, are provided behind the front blades by one or more sheets. ing.

  In the wind direction adjusting device configured as described above, the adjusted wind is distributed by the rear blade, and then is distributed by the front blade in another direction. However, for example, considering the front blade that distributes the adjustment air in the vertical direction, it seems that the adjustment air is blown out along the inclined surface of the front blade that is inclined upward at first glance. The adjustment wind is blown only at an angle smaller than the inclination angle of the front blade.

  The following is considered as the cause. That is, at the front end side of the inclined front blade, the adjustment air that has traveled straight along the inner surface of the lower wall of the case body becomes a horizontal air and is blown out from the air outlet. Due to the influence of the wind blown in the horizontal direction, the adjustment air that has been distributed upward by the front blades is pushed downward. This is considered as one of the causes.

  In addition, when the adjustment wind that has been traveling straight in the case hits the upper surface of the inclined front blade, a part of the adjustment wind that has hit the upper surface of the inclined front blade is rebounded by the front blade, and the front blade It will flow in a direction different from the flow along the upper surface of. Then, the rebounded adjustment wind hits the lower surface of another front blade disposed adjacent to the rebounded front blade. Furthermore, the adjustment wind that hits the lower surface of the adjacent front blades is bounced back again, so that a turbulent flow is generated between the adjacent front blades. Due to the influence of the turbulent flow generated in this way, the air volume in the air distribution direction by the front blades is attenuated. This is also considered as one of the causes.

  A vehicle air conditioner (see Patent Document 1) has been proposed as a solution to the problem caused by the cause thus considered. In the vehicle air conditioner described in Patent Document 1, a plurality of wind direction adjusting blades are arranged in parallel on the air outlet side of the air conditioning case. The plurality of wind direction adjusting blades are configured to rotate in conjunction with each other.

On the upstream side of the air conditioning case, which is the rear side of the airflow direction adjusting blade, a plurality of guide blades are provided in parallel. The plurality of guide vanes are configured to rotate in conjunction with each other. Further, the rotation axis of each wind direction adjusting blade and the rotation axis of each guide blade are arranged in parallel to each other. When each wind direction adjusting blade is rotated by the operating means, The adjustment blade rotates in the opposite direction to the rotation direction.

  Since it is comprised in this way, the adjustment wind supplied in the air conditioning case will be initially distributed by each guide blade. The adjusted wind distributed by each guide blade is then distributed by the respective wind direction adjusting blades in a direction that is line-symmetric with the wind distribution direction by the guide blade. Then, the flow of the adjustment wind becomes a meandering laminar flow due to each guide blade and each wind direction adjustment blade.

  In particular, since the opening area at the air outlet is large, the adjustment wind that flows meanderingly and laminarly by each guide blade and each wind direction adjusting blade is suitably distributed by each wind direction adjusting blade. The air is blown out from the air outlet in the direction in which the air is distributed.

Microfilm of Japanese Utility Model Application No. 01-136072 (Japanese Utility Model Application Publication No. 03-75014)

  In the invention described in Patent Document 1, the adjustment wind can be a meandering laminar flow by the guide vanes and the wind direction adjustment vanes. Finally, the adjustment wind flows along the inclination direction of each wind direction adjusting blade and is blown out from the air outlet.

  In the invention described in Patent Document 1, in order to make the flow flow along the inclination direction of each wind direction adjusting blade and blow the adjusted wind from the air outlet, the adjustment is performed by each guide blade and each wind direction adjusting blade. It must be a laminar flow that snakes the wind. However, as the adjustment wind is meandered, the wind speed of the adjustment wind decreases.

  In addition, the invention described in Patent Document 1 can be suitably applied particularly when the opening area at the air outlet is large, but conversely, the opening area at the air outlet is thin. For the so-called thin wind direction adjusting device, a meandering laminar flow cannot be sufficiently generated in the air conditioning case. Therefore, it is difficult to sufficiently exhibit the effects of the invention described in Patent Document 1.

  In particular, when applied to a thin wind direction adjusting device, it is difficult to arrange a plurality of guide vanes and wind direction adjusting vanes in the air conditioning case. That is, in a thin wind direction adjusting device, the number of guide blades and wind direction adjusting blades arranged is one or at most two. As a result, the rate at which the adjustment air passes as a straight flow from between the both ends of the guide vanes and the inner wall of the air conditioning case increases, and so-called blow-off air is generated.

  In the present invention, while solving the above-mentioned problems in the prior art, the direction of the adjustment air blown out from the air outlet can be controlled to the air distribution direction along the inclination direction of the air direction adjusting blade arranged in the air outlet. In addition, it is possible to increase the wind speed of the adjustment air blown from the air outlet, and to provide a wind direction adjusting device that can achieve these effects even when it is thin. I have to.

The object of the present invention can be achieved by the wind direction adjusting device described in claims 1 to 7.
That is, in the present invention, it has a wind direction adjusting blade pivotally attached to the air outlet side of the air conditioning case, and a guide blade pivotally attached to the rear side of the wind direction adjusting blade on the upstream side in the air conditioning case,
The rotating shaft of the wind direction adjusting blade and the rotating shaft of the guide blade are arranged in parallel to each other, and the wind direction adjusting blade and the guide blade are interlocked so as to be in the same inclination direction by the operating means. The most important feature is that the adjustment wind that rotates and flows in the air conditioning case is first throttled by the guide blade and the inner wall of the air conditioning case and then supplied to the wind direction adjustment blade.

  Further, in the present invention, the rotation axis of the guide blade is disposed at a position in front of the front end of the guide blade, and the rotation axis of the wind direction adjusting blade is at a position on the front end side of the wind direction adjusting blade. The wind direction adjusting blade and the guide blade are rotated in conjunction with each other in the same rotation direction by the operating means, and the width dimension of the guide blade is the width dimension in the front-rear direction of the air conditioning case. The main feature is that the wind direction adjusting blade is shorter than the width dimension.

  Further, in the present invention, when the operation means is interlocked and rotated, the rotation angle of the guide blade is larger than the rotation angle of the wind direction adjusting blade, and the wind direction adjusting blade is at a maximum angle. The main feature is that at least the rear edge of the guide vane is disposed at a position close to the inner surface of the air conditioning case.

  Furthermore, the main feature of the present invention is that the rotation shaft of the airflow direction adjusting blade and the rotation shaft of the guide blade are arranged on the same straight line in the front-rear direction of the air conditioning case.

  In the invention of the present application, the air distribution direction is different from the air distribution direction of the wind direction adjusting blades at an intermediate position between the wind direction adjusting blades and the guide blades or a position ahead of the wind direction adjusting blades. The main feature is that the blades are axially attached.

  Further, in the present invention, a plurality of the wind direction adjusting blades, the guide blades, and the wind distributing blades are respectively disposed, and the plurality of the wind direction adjusting blades, the plurality of guide blades, and the plurality of the wind distributing blades. The main feature is that the same blades rotate in conjunction with each other.

  Furthermore, the main feature of the present invention is that an inclined surface that expands outward is formed at the end of the air conditioning case on the air outlet side.

  In this invention, the 1st aperture | diaphragm | squeeze part with respect to adjustment wind is comprised with the guide blade | wing and the case inner wall. Then, the adjusted wind that has been throttled by the first throttle portion and has a high flow velocity becomes a laminar flow and is supplied to the wind direction adjusting blade as it is. And the adjustment wind supplied to the wind direction adjustment blade is blown out from the air outlet along the direction of the wind direction adjustment blade.

  Moreover, since the second throttle part is formed by the wind direction adjusting blade and the case inner wall, the adjustment wind is further accelerated in the second throttle part and is blown out from the air outlet. Become.

  Since the adjustment wind that has been squeezed into a laminar flow is distributed by the wind direction adjusting blade, the adjustment wind blown from the air outlet is not affected by the blow-through air. As a result, the adjustment wind distributed by the airflow direction adjusting blade is not reduced in the airflow distribution direction by the airflow direction adjusting blade, and is directly flown along the air distribution direction and blown out from the air outlet. Become. As a result, the distribution area of the adjustment wind can be configured to have a wide angle without being affected by the blow-by wind.

  In the present invention, the rotation axis of the guide vane can be disposed in front of the front end of the guide vane, and the rotation axis of the wind direction adjusting vane is arranged at a site on the front end side of the wind direction adjusting vane. Can be set up. In addition, the wind direction adjusting blade and the guide blade can be rotated in conjunction with each other in the same rotation direction by the operating means. Furthermore, as the width dimension in the front-rear direction of the air conditioning case, the width dimension of the guide blade can be configured to be shorter than the width dimension of the airflow direction adjustment blade.

  With this configuration, the adjustment wind is not greatly reduced in the first throttle portion using the guide blades, and the adjustment wind is not greatly reduced in the second throttle portion using the wind direction adjustment blades. Therefore, it is possible to reduce the pressure loss generated in the first throttle part and the second throttle part with respect to the adjustment wind. Thereby, it can prevent that the wind speed of the adjustment wind blown off from an air blower outlet reduces.

  In the present invention, when the wind direction adjusting blade and the guide blade are rotated by the operation means, the rotation angle of the guide blade is configured to be larger than the rotation angle of the wind direction adjusting blade. Can do. Moreover, when the wind direction adjusting blade is rotated to the maximum angle, at least the rear edge of the guide blade can be arranged at a position close to the inner surface of the air conditioning case.

  By configuring in this way, when the wind direction adjusting blade is rotated to the maximum angle, it is possible to prevent a blow-off wind from being generated from the gap between the rear edge of the guide blade and the inner surface of the air conditioning case. I can leave. And wind distribution by a wind direction adjustment blade can be performed more reliably.

  In the present invention, the rotation axis of the wind direction adjusting blade and the rotation shaft of the guide blade can be arranged on the same straight line in the front-rear direction of the air conditioning case. With this configuration, when the wind direction adjusting blades and the guide blades are arranged in a horizontal state, the wind direction adjusting blades and the guide blades can be arranged in a straight line with respect to the flow of the adjusting wind. And the pressure loss with respect to the adjustment wind by a wind direction adjustment blade | wing and a guide blade | wing can be reduced.

  Moreover, the designability in the front view of a wind direction adjustment apparatus can be improved. In particular, when the number of wind direction adjusting blades and the number of guide blades are set, for example, one by one as in the configuration of a thin wind direction adjusting device, the design of the wind direction adjusting device in front view is improved. It can be greatly improved.

In the present invention, the air distribution blade that distributes air in a direction different from the air distribution direction by the air direction adjusting blade is disposed at an intermediate position between the air direction adjusting blade and the guide blade, or at a position ahead of the air direction adjusting blade. I can leave.
In this way, by providing the air distribution blades, the wind direction of the adjustment air blown from the air direction adjusting device can be controlled in two different directions.

In the present invention, the number of wind direction adjusting blades, the number of guide blades, and the number of wind vanes can be configured in plural. That is, the present invention can be suitably applied to a thin wind direction adjusting device or a wind direction adjusting device having a large opening area at the air outlet.

  In this invention, the inclined surface which expands toward the outer side can be formed in the edge part in the air blower outlet side of an air-conditioning case. By comprising in this way, it can prevent that a turbulent flow generate | occur | produces in the edge part of an air-conditioning case. In addition, air resistance at the end of the air conditioning case can be reduced, and wind noise can be prevented.

  A plurality of air distribution blades 6 are arranged on the upstream side of the air-conditioning case 2 on the rear side of the wind direction adjusting blades 4. As shown in FIG. 2, one guide blade 5 is disposed on the upstream side of the air conditioning case 2, which is the rear side of the air distribution blade 6. The wind direction adjusting blade 4 and the guide blade 5 are configured to rotate in the same direction via the first link portion 10.

  Therefore, a first arc groove 12 and a second arc groove 13 for rotating the wind direction adjusting blade 4 and the guide blade 5 in conjunction with each other are formed on both side surfaces of the air conditioning case 2. In each first arc groove 12, a fitting shaft 4c formed at the corner of the rear end edge of the airflow direction adjusting blade 4 is slidably inserted in the groove, and in each second arc groove 13, The connecting shaft 5b formed on the side surface of the guide blade 5 is slidably inserted in the groove.

  The end of the fitting shaft 4c is fitted in a fitting hole 20a formed on one end side of the intermediate member 20. The cross-sectional shapes of the fitting shaft 4c and the fitting hole 20a can each be formed in a rectangular shape or the like, so that relative rotation does not occur between the fitting shaft 4c and the fitting hole 20a. It is configured.

  A connecting shaft 4 b is formed on the other end side of the intermediate member 20, and the connecting shaft 4 b is pivotally supported by a shaft hole 10 a on one end side of the first link portion 10. Further, the connecting shaft 5 b of the guide blade 5 is pivotally supported by the shaft hole 10 b on the other end side of the first link portion 10.

Show. However, in this invention, it is not limited to this structure, The connection position of the 1st link part 10 and the wind direction adjustment blade | wing 4 shall be comprised in the back side position rather than the rear-end edge of the wind direction adjustment blade | wing 4. Other configurations can be employed as long as the configuration can be used.

  Further, in the present invention, the connecting position of the first link portion 10 and the wind direction adjusting blade 4 is not limited to the position on the rear side of the rear end edge of the wind direction adjusting blade 4. The connecting shaft 4b may be formed at the end edge, and the connecting shaft 4b may be configured to be slidable in the first arc groove 12.

  When the wind direction adjusting blade 4 rotates about the rotating shaft 4a formed at the corner of the tip edge of the wind direction adjusting blade 4, the intermediate member 20 together with the wind direction adjusting blade 4 is integrally centered on the rotating shaft 4a. It can be rotated. The rotation of the wind direction adjusting blade 4 is transmitted to the first link portion 10 via the intermediate member 20, and the guide blade 5 can be rotated about the rotation shaft 5a.

  That is, as shown in FIG. 3, the wind direction adjusting blade 4 can rotate around a rotating shaft 4 a formed at a corner portion at the tip edge of the wind direction adjusting blade 4, and the guide blade 5 It is possible to rotate around a rotation shaft 5a formed further forward than the corner at the tip edge.

  The rotation axis 5a of the guide blade 5 is configured to be pivotally supported by a portion of the side surface of the air conditioning case 2 on the front side of the front end of the guide blade 5, and the rotation axis 4a of the airflow direction adjustment blade 4 is The air-conditioning case 2 is pivotally supported on the side portion of the air conditioning case 2 that is the front end side of the wind direction adjusting blade 4.

  Further, the width dimension of the airflow direction adjusting blade 4 that is the width in the front-rear direction of the air conditioning case 2 is configured to be longer than the width dimension of the guide blade 5. As shown in FIGS. 1 and 2, the distance between the connecting shaft 4b and the rotating shaft 4a provided on the intermediate member 20 that rotates integrally with the wind direction adjusting blade 4, and the connecting shaft 5b of the guide blade 5 and the rotating Since it is configured to be longer than the distance to the shaft 5a, the rotation angle of the wind direction adjusting blade 4 can be made smaller than the rotation angle of the guide blade 5. The groove radius of the first arc groove 12 is configured to be larger than the groove radius of the second arc groove 13.

  As shown in FIG. 2, the rotation shaft 6 a of each air distribution blade 6 is pivotally supported by a plurality of pivot support holes 8 a formed on the opposing inner surfaces of the pair of spacers 8. The pair of spacers 8 can be attached to the upper and lower inner surfaces on the air outlet 3 side of the air conditioning case 2 in a state where both ends of the rotating shaft 6a of each air distribution blade 6 are pivotally supported.

  On the rear end side of each air distribution blade 6, a connection shaft 6 b for rotating each air distribution blade 6 is formed, and each connection shaft 6 b is pivotally supported by the second link portion 11. Has been. As a configuration of the link mechanism for rotating the plurality of wind distributing blades 6 in conjunction with each other, a configuration using the second link portion 11 is illustrated. As this link mechanism, a conventionally known link mechanism is used. Can be adopted.

  As shown in FIGS. 2 and 3, a pair of fork portions 7 a are extended at the rear end portion of the operation knob 7. A shaft portion for engaging the pair of fork portions 7a is formed on the front edge portion 18a of the air distribution blade 6 facing the pair of fork portions 7a, and a pair of forks is disposed on the rear side of the shaft portion. An opening 18b that prevents interference with the portion 7a is formed.

  By sliding the operation knob 7 along the longitudinal direction of the wind direction adjusting blade 4, the air distributing blade 6 engaged with the pair of fork portions 7a can rotate about the rotating shaft 6a. . Then, the rotation of the air distribution blades 6 is transmitted to the remaining air distribution blades 6 through the second link portion 11, and all the air distribution blades 6 can be rotated in conjunction with each other.

  As shown in FIG. 2, a locking portion 3b for locking a locked portion 9a formed on the back surface of the panel portion 9 is formed on the front side of the air outlet 3 and the locked portion 9a is By engaging with the engaging portion 3b, the wind direction adjusting device 1 including the panel portion 9 can be assembled as shown in FIG.

  Next, the structure which rotates the wind direction adjustment blade | wing 4 and the guide blade | wing 5 by operating the operation knob 7 which is not shown in figure using FIGS. 4-7 is demonstrated. 4 to 7, the illustration of the operation knob 7 and the illustration of the air distribution blade 6 are omitted.

  FIG. 4 shows a state in which the wind direction adjusting blade 4 is rotated to the maximum angle in the counterclockwise direction on the paper surface about the rotation shaft 4a by operating the operation knob 7 (not shown). When the wind direction adjusting blade 4 rotates, the guide blade 5 can also rotate in the same rotation direction as the wind direction adjusting blade 4 via the first link portion 10, the first arc groove 12 and the second arc groove 13. .

  At this time, the wind direction adjusting blade 4 rotates around the rotating shaft 4a disposed on the leading edge side of the wind direction adjusting blade 4, whereas the guide blade 5 is on the front side of the leading edge of the guide blade 5. It rotates about a rotation shaft 5a arranged in the center. In addition, the position where the connecting shaft 4b provided on the intermediate member 20 that rotates integrally with the wind direction adjusting blade 4 on one end side of the first link portion 10 is pivotally supported than the rear end edge of the wind direction adjusting blade 4 The position where the connecting shaft 5b of the guide blade 5 is pivotally supported at the other end side of the first link portion 10 is disposed at the position on the tip edge side of the guide blade 5.

  Thus, the distance between the connecting shaft 4b provided on the intermediate member that rotates integrally with the wind direction adjusting blade 4 and the rotating shaft 4a is longer than the distance between the connecting shaft 5b and the rotating shaft 5a in the guide blade 5. As a result, the rotation angle of the guide blade 5 is larger than the rotation angle of the wind direction adjusting blade 4. Further, in order to correspond to the rotation angle of the wind direction adjusting blade 4 and the rotation angle of the guide blade 5, the arc diameter of the first arc groove 12 is formed larger than the arc diameter of the second arc groove 13.

Further, since the width dimension in the width direction of the guide blade 5 is configured to be shorter than the width dimension in the width direction of the wind direction adjusting blade 4, when the wind direction adjusting blade 4 is rotated to the maximum angle, the guide blade 5 The rear edge can be arranged at a position close to the inner wall surface 2a on the lower side of the air conditioning case 2.

  As a result, it is possible to suppress the occurrence of blow-through air between the rear end edge of the guide blade 5 and the inner wall surface 2a on the lower side of the air conditioning case 2. In addition, at this time, a sufficient interval can be formed between the leading edge of the airflow direction adjusting blade 4 and the inner wall surface 2a on the upper side of the air conditioning case 2 to blow out the adjusted airflow.

  In the illustrated example, the configuration in which the spacer 8 attached to the inner wall surface 2a is arranged at the tip of the rear end edge of the wind direction adjusting blade 4 is rotated. However, the spacer that supports the air distributing blade 6 is supported. For example, the air distribution blades 6 can be disposed on the front side of the wind direction adjusting blades 4 by changing the arrangement position of 8.

  A first throttle portion can be formed between the guide blade 5 and the inner wall surface 2 a on the upper side of the air conditioning case 2. As indicated by the arrow of the flow of the adjustment wind, the adjustment wind that has passed through the first throttle part can be supplied to the wind direction adjusting blade 4 as a laminar flow. The adjusted wind supplied to the wind direction adjusting blade 4 is distributed based on the inclination angle of the wind direction adjusting blade 4.

  That is, a second throttle part is formed between the leading edge of the wind direction adjusting blade 4 and the inner wall surface 2a on the upper side of the air conditioning case 2, and the adjusted wind increased by the second throttle part is supplied to the air outlet 3 Will be blown out.

  Further, since the widened portion 3a is formed at the opening end of the air outlet 3, the adjustment air distributed by the wind direction adjusting blade 4 can flow along the surface of the widened portion 3a. By forming the widened portion 3a, it is possible to prevent the adjustment wind from being separated at the opening end of the air outlet 3, and to prevent the occurrence of turbulence caused by the separation. Thereby, the adjustment wind distributed based on the inclination angle of the wind direction adjusting blade 4 can be blown out over a wide range without reducing the flow velocity.

  FIG. 5 shows a view in which the wind direction adjusting blades 4 and the guide blades 5 are arranged in a horizontal state, and the wind direction adjusting blades 4 and the guide blades 5 can be arranged on the upper and lower central surfaces of the air conditioning case 2. As a result, in the front view of the wind direction adjusting device 1, the wind direction adjusting blade 4 and the guide blade 5 are arranged at the center of the air conditioning case 2 in the vertical direction, and the design for the wind direction adjusting device 1 is greatly improved. Can do.

  In addition, since the wind direction adjusting blade 4 and the guide blade 5 can be arranged on a horizontal surface, the flow of the adjusting air is parallel to the straight air flowing in the air conditioning case 2 as indicated by an arrow. Can be arranged. As a result, compared to the case where the wind direction adjusting blades 4 and the guide blades 5 are arranged in steps, the pressure loss with respect to the adjusted air can be greatly reduced.

  FIG. 6 shows a state in which the wind direction adjusting blade 4 and the guide blade 5 are rotated to their maximum angles in the opposite direction to FIG. Also at this time, the rear end edge of the guide blade 5 is arranged at a position close to the inner wall surface 2a on the upper side of the air conditioning case 2. With this configuration, the first throttle portion can be formed between the leading edge of the guide blade 5 and the inner wall surface 2a on the lower side of the air conditioning case 2.

  Further, since the rear edge of the guide blade 5 can be brought close to the inner wall surface 2a on the upper side of the air conditioning case 2, it is between the rear edge of the guide blade 5 and the inner wall surface 2a on the upper side of the air conditioning case 2. The generation of wind blown air can be suppressed. In addition, at this time, a sufficient interval can be formed between the leading edge of the wind direction adjusting blade 4 and the inner wall surface 2a on the lower side of the air conditioning case 2 to blow out the adjusted air.

  As indicated by the arrow of the flow of the adjustment wind, the adjustment wind that has been throttled and accelerated by the first throttle section is supplied to the wind direction adjustment blade 4, and a desired wind distribution is provided by the wind direction adjustment blade 4. Will be blown out in the direction. Since the widened portion 3a is formed at the opening end of the air outlet 3, it is necessary to prevent the wind speed of the adjustment wind distributed by the wind direction adjusting blade 4 from being reduced by the occurrence of turbulence. Can do.

  Thus, since the wind direction of the adjusted wind is controlled by the two-stage configuration of the guide blade 5 and the wind direction adjusting blade 4, even if it is configured as a thin wind direction adjusting device 1, it is blown out from the air outlet 3 The distribution range of the adjusted wind can be configured over a wide range, and the wind speed of the adjusted wind blown from the air outlet 3 can be prevented from being reduced.

  FIG. 7 shows a case where the wind direction adjusting blade 4 and the guide blade 5 are rotated upward in the counterclockwise direction with respect to the paper surface as indicated by an arrow and indicated by an imaginary line. The case where it is rotated downward, which is a clockwise direction, is illustrated together. As shown in FIG. 7, when the wind direction adjusting blade 4 and the guide blade 5 are rotated in both the upper and lower directions, the distance between the leading edge of the air direction adjusting blade 4 and the inner wall surface 2a of the air conditioning case 2 is the guide blade. 5 can be formed wider than the distance between the front edge of 5 and the inner wall surface 2a of the air conditioning case 2, and the rear edge of the guide blade 5 is disposed in the state of being close to the inner wall surface 2a of the air conditioning case 2. I can keep it.

  Since it can be configured in this way, the adjustment wind can be efficiently throttled by the tip edge of the guide blade 5 and the inner wall surface 2a of the air conditioning case 2, and the adjustment wind that has been squeezed into a laminar flow can be adjusted in the wind direction Wind can be distributed with the blade 4. In addition, the wind speed of the adjustment wind is increased by the first-stage aperture by the guide blade 5 and the second-stage aperture by the wind direction adjustment blade 4. In the state where the wind speed is increased, the adjusted wind can be directed in the direction of air distribution by the wind direction adjusting blades 4.

  In the first embodiment, the structure in which the wind direction adjusting blade 4 and the guide blade 5 are interlocked and rotated by the link mechanism using the first link portion 10 has been described. In the second embodiment, the wind direction adjusting blade 4 and the guide blade 5 are configured to rotate together using a gear mechanism instead of using a link mechanism. Other configurations are the same as the configurations in the first embodiment, and members having the same configurations as the members in the first embodiment are denoted by the same reference numerals and the description of the members is omitted. To do.

  As shown in FIG. 8, the wind direction adjusting blade 4 can be rotated around a rotation shaft 4 a formed at a corner portion at the tip edge of the wind direction adjusting blade 4, and the guide blade 5 can be rotated at the tip of the guide blade 5. It can be rotated around a rotation shaft 5a formed further forward than the corner portion at the edge.

The rotating shaft 4a of the airflow direction adjusting blade 4 is pivotally supported by a portion of the side wall of the air conditioning case 2 so as to be rotatable. The rotating shaft 4a extends outward from the side wall of the air conditioning case 2 and is fixed to a first driven gear 16 disposed on the outside of the outer wall of the air conditioning case 2 as shown in FIGS. ing.
That is, the rotation shaft 4 a is fixed to the main portion of the fan in the first driven gear 16 formed in a fan shape, and can rotate integrally with the first driven gear 16.

The rotating shaft 5a of the guide blade 5 is rotatably supported on the side wall of the air conditioning case 2. The rotating shaft 5a extends outward from the side wall of the air conditioning case 2, and is fixed to a second driven gear 17 disposed on the outside of the outer wall of the air conditioning case 2 as shown in FIGS. .
In other words, the rotation shaft 5 a is fixed to the main portion of the fan in the second driven gear 17 formed in a sector shape, and can rotate integrally with the second driven gear 17.

  The first driven gear 16 and the second driven gear 17 mesh with the transmission gear 15 that is pivotally supported on the side wall of the air conditioning case 2.
