Description

  The present invention relates to an air-conditioning register that changes the flow direction of air-conditioning air sent from an air-conditioning apparatus and blows out the air from an outlet.

  An air conditioning register that changes the flow direction of the air conditioning air sent from the air conditioner and blows it into the vehicle interior is incorporated in an instrument panel or the like of the vehicle. Some air conditioning registers include a retainer, a plurality of plate-like downstream fins, and a plurality of plate-like upstream fins (see Patent Document 1). The retainer has a ventilation passage for air for air conditioning inside. The downstream end of the ventilation path in the air-conditioning air flow direction constitutes the air-conditioning air outlet.

  Each downstream fin is arrange | positioned upstream of a blower outlet in a ventilation path, and is supported by the retainer so that tilting is possible. Each upstream fin is disposed upstream of the downstream fin in the ventilation path and orthogonal to the downstream fin, and is supported by the retainer so as to be tiltable. The air-conditioning air flows along these upstream fins and downstream fins, and is then blown out from the outlet. When at least one of the upstream fin and the downstream fin is tilted, the flow direction of the air for air conditioning is changed.

JP 2013-116650 A

  By the way, among the components of the air-conditioning register, components such as the downstream fin and the upstream fin arranged in the ventilation path become ventilation resistance and cause pressure loss. This pressure loss is minimized when the downstream fin and the upstream fin are parallel to the flow direction of the air-conditioning air before passing through them (neutral state). At this time, the substantial opening area of the air outlet is maximized. The substantial opening area is an area of a portion where the above components are not projected on a surface orthogonal to the flow direction of the air-conditioning air at the air outlet.

  Then, as at least one of the downstream fin and the upstream fin is tilted and the angle formed with respect to the neutral state is increased, the substantial opening area of the outlet is reduced and the pressure loss is increased. Thus, when the flow direction of the air for air conditioning is changed, the pressure loss greatly fluctuates.

  Such a phenomenon is particularly likely to occur in a thin air-conditioning register in which the size of the air outlet is greatly different between the vertical direction and the horizontal direction. This is because the proportion of the downstream fins and the upstream fins in the ventilation path is large.

  The present invention has been made in view of such circumstances, and an object thereof is to provide an air-conditioning register that can suppress fluctuations in pressure loss caused by a change in the flow direction of air-conditioning air. It is in.

  An air-conditioning register that solves the above problem includes a retainer having a common inlet for air-conditioning air at one end and a pair of outlets arranged in parallel with each other at the other end, and the interior of the retainer Is provided with an air passage including a common passage portion connected to the common inlet and a pair of branch passage portions branched from the common passage portion and guiding the air-conditioning air that has passed through the common passage portion to each outlet. The downstream end of each branch passage in the air-conditioning air flow direction is formed such that the distance from the downstream end of the other branch passage is narrower toward the downstream. A movable panel is provided that moves so that the sum of the opening areas of the two outlets is constant in a movable region including a closed position that closes the entire outlet and the closed position that closes the other outlet. Yes.

  According to said structure, when a movable panel exists in the center position between both obstruction | occlusion positions, both blower outlets are opened to the same extent. Therefore, after the air for air conditioning flows along the common passage portion, it is divided into one that flows through one of the pair of branch passage portions and the other that flows through the other, and is blown out from the outlet. The blowing direction of the air-conditioning air from the outlet is determined by the direction in which the downstream end of the branch passage extends.

  Here, the downstream end portion of each branch passage portion is formed such that the distance from the downstream end portion of the other branch passage portion becomes narrower toward the downstream side. From this, the air-conditioning air that has flowed along the downstream end of each branch passage portion flows in a direction approaching each other after being blown out from the air outlet. Then, both air-conditioning airs merge to change the flow direction to an intermediate direction between the air-conditioning air flow directions.

  When the movable panel is in one of the closed positions, the air-conditioning air is restricted from flowing in the branch passage portion having the closed outlet. Accordingly, the air-conditioning air that has flowed through the common passage portion flows along the branch passage portion that does not block the air outlet, and is then blown out from the air outlet. In this case, since the air-conditioning air is not blown out from the blocked outlet, the air-conditioning air does not merge to change the flow direction. As a result, the air-conditioning air flows in a direction along the downstream end of the branch passage portion that does not block the air outlet.

  When the movable panel is at a position between the central position between the two closed positions and one of the closed positions, the degree of closure by the movable panel is different for each outlet. In the branch passage portion in which the air outlet is largely blocked by the movable panel, the air-conditioning air is more strongly restricted from flowing than in the branch passage portion in which the air outlet is less blocked. Accordingly, more air-conditioning air is blown out from the outlet of the latter branch passage portion than from the outlet of the former branch passage portion. Then, the air-conditioning air flows together and flows in a direction intermediate between the flow directions of the air-conditioning air and close to the direction in which a lot of air-conditioning air flows.

  As described above, by changing the position of the movable panel, the flow direction of the air-conditioning air finally toward the user can be changed. However, the sum of the opening areas of both outlets is independent of the position of the movable panel. It is constant. In addition, each branch passage portion is not provided with a member corresponding to a fin for changing the flow direction of the air-conditioning air in the juxtaposed direction of the two outlets, that is, a member serving as ventilation resistance. Therefore, the amount of fluctuation in pressure loss that occurs when the flow direction of the air-conditioning air that finally travels to the user is changed is reduced.

  In the air-conditioning register, upstream of the movable panel in the retainer, a plate-like upstream fin extending in the direction in which both the air outlets are arranged is provided so as to be tiltable in a direction perpendicular to the direction in which the air outlet is arranged. It is preferable.

  According to said structure, the air for an air conditioning blows off from a blower outlet, after flowing along an upstream fin. The upstream fin is tilted in a direction perpendicular to the direction in which the two air outlets are juxtaposed, whereby the direction of the air-conditioning air flowing along the upstream fin is changed, and the air is blown out from the open air outlet.

  In the air conditioning register, the movable panel is preferably provided with an operation knob driven and connected to the upstream fin so as to be slidable in a direction orthogonal to the parallel arrangement direction.

  According to the above configuration, when the operation knob is slid along the movable panel in the direction orthogonal to the direction in which the two outlets are arranged, the movement of the operation knob is transmitted to the upstream fin, and the upstream fin is It is tilted in a direction orthogonal to the juxtaposed direction.

  In the air-conditioning register, upstream of the upstream fin in the retainer, a part of each branch passage portion is configured and tilted in conjunction with the movable panel so that the movable panel moves forward in the moving direction. It is preferable to provide a movable fin that narrows the branch passage and expands the branch passage at the rear in the moving direction.

  According to said structure, if a movable panel is moved to the juxtaposition direction of both blower outlets, the blower outlet in the front of the movement direction will be blocked more than the blower outlet in back of a moving direction. The movable fin tilts in conjunction with the movable panel upstream of the upstream fin in the retainer. The movable fins narrow the branch passage portion ahead of the movable panel in the movement direction and widen the branch passage portion rearward in the movement direction.

  Accordingly, the flow direction of the air-conditioning air can be changed by flowing along the movable fins. The air-conditioning air flows more in the branch passage portion where the air outlet is not so than in the branch passage portion where the air outlet is largely blocked by the movable panel. As a result, more air-conditioning air is introduced to the downstream end of the branch passage having the other outlet than to the downstream end of the branch passage having the outlet closed by the movable panel. It is burned. The air-conditioning air flowing along the downstream end of the latter branch passage portion increases, and the directivity is enhanced.

  In the air conditioning register, a support arm extending upstream in the flow direction is connected to the movable panel, and the support arm can be tilted at least in the juxtaposition direction with respect to the retainer by a support shaft. It is preferable that the movable fin is provided integrally with the movable panel.

  According to the above configuration, when the support arm is tilted with respect to the retainer with the support shaft as a fulcrum, the movable panel moves in the direction in which both the air outlets are arranged. Further, the movable fin integrated with the movable panel tilts with respect to the retainer with the support shaft as a fulcrum, narrowing the branch passage portion in the moving direction of the movable panel and expanding the branch passage portion in the rear in the moving direction. At the downstream end portion of the expanded branch passage portion, more air for air conditioning flows along the downstream end portion.

In the air conditioning register, it is preferable that a fixed fin is provided upstream of the movable fin in the retainer.
According to said structure, the airflow for an air conditioning which flows through a branch channel | path part can change a flow direction by flowing along the fixed fin upstream of a movable fin. A part of the air for air conditioning can be changed in the flow direction by the movable fin. As described above, the air-conditioning air can be changed its flow direction twice by the fixed fin and the movable fin. Therefore, it is possible to suppress a sudden change in the flow direction by changing the flow direction little by little in each of the fixed fin and the movable fin.

  In the air-conditioning register, the support arm is supported by the support shaft so as to be tiltable and movable in the air-conditioning air flow direction with respect to the retainer, and the retainer is provided with a locked portion, At least one of the movable panel and the support arm is locked to the locked portion by moving in one of the flow directions, and the locked portion is moved to the other of the movable direction and the other in the flow direction. A locking portion for releasing the locking state is provided, and the support arm is provided between the retainer and the support arm in a direction to lock the locking portion to the locked portion. It is preferable that an elastic member is provided.

  According to said structure, the urging | biasing force of an elastic member acts on a latching | locking part via a support arm at least. When the locking portion is locked to the locked portion provided in the retainer by this urging force, the support arm is restricted from tilting with the support shaft as a fulcrum. A movable panel is hold | maintained in the position at that time in the juxtaposition direction of both blower outlets.

  On the other hand, when a force toward the direction against the urging force of the elastic member is applied to the movable panel, and the movable panel is moved in the same direction, the locked portion is locked to the locked portion. Is released. Therefore, it is possible to move the movable panel in the parallel direction by tilting the support arm with the support shaft as a fulcrum. When the movable panel is moved to a desired position, when the application of the force to the movable panel is stopped, the locking portion is locked again by the urging force of the elastic member.

  According to the air conditioning register, it is possible to suppress a variation in pressure loss caused by a change in the flow direction of air conditioning air.

It is a figure which shows one Embodiment actualized to the air-conditioning register | resistor for vehicles, and is the front view which looked at the air-conditioning register | resistor with which the movable panel was hold | maintained in the neutral position from the downstream in the blowing direction of air-conditioning air.

FIG. 3 is a cross-sectional view of the air-conditioning register corresponding to FIG. 2, with the movable panel held at the upper closed position. FIG. 3 is a cross-sectional view of the air-conditioning register corresponding to FIG. 2, with the movable panel held at the lower closed position.

Hereinafter, an embodiment embodied in a vehicle air-conditioning register will be described with reference to the drawings.
In the following description, it is assumed that the traveling direction (forward direction) of the vehicle is the front, the backward direction is the rear, and the height direction is the vertical direction. Moreover, about a vehicle width direction (left-right direction), a direction is prescribed | regulated on the basis of the case where a vehicle is seen from back.

  In the passenger compartment, an instrument panel is provided in front of the front seats (driver's seat and front passenger seat) of the vehicle, and air-conditioning registers are incorporated in the center, side, etc. in the vehicle width direction. The main functions of this air-conditioning register are to change the flow direction of air-conditioning air (hot air and cold air) sent from the air-conditioner and blow it out into the passenger compartment, and to block the air-conditioning air from blowing out. is there.

  As shown in FIGS. 1, 2 and 3A, the air conditioning register includes the retainer 10, the movable panel 30, the panel position adjusting mechanism 35, the upstream fin 50, the operation knob 55, the movable fin 60, the fixed fin 65, and the like. A shut damper 70 is provided. Next, each part which comprises the register | resistor for an air conditioning is demonstrated in order.

<Retainer 10>
The retainer 10 is a member constituting the outer shell portion of the air conditioning register. The retainer 10 includes an upper wall portion 11 and a lower wall portion 12 that are arranged apart from each other in the vertical direction, and a pair of side wall portions 13 that are arranged apart from each other in the vehicle width direction. A cylindrical shape extending substantially in the front-rear direction with a slight inclination is formed. The retainer 10 has a common inlet 14 for air-conditioning air A1 at its front end. The common entrance 14 has a horizontally long rectangular shape whose dimension in the vehicle width direction is larger than the dimension in the vertical direction.

  The retainer 10 has a pair of outlets 15 and 16 at its rear end. Both the air outlets 15 and 16 are juxtaposed in a state of being separated from each other in the vertical direction. Each of the air outlets 15 and 16 has a horizontally long rectangular shape whose dimension in the vehicle width direction is larger than that in the vertical direction. Both the air outlets 15 and 16 have the same shape or a shape close to each other. The air outlets 15 and 16 are formed so that the sum of their opening areas is the same as or close to the opening area of the common inlet 14.

As shown in FIGS. 2 and 3A, the front portion 11f of the upper wall portion 11 and the front portion 12f of the lower wall portion 12 of the retainer 10 are formed in a flat plate shape so as to be substantially parallel to each other. Yes.
The rear end portion 11r of the upper wall portion 11 and the rear end portion 12r of the lower wall portion 12 are formed in a flat plate shape that is inclined so that the distance from each other decreases toward the downstream side. Specifically, the rear end portion 11r is formed in a flat plate shape that is inclined so as to be lower toward the rear, and the rear end portion 12r is formed in a flat plate shape that is inclined so as to be higher toward the rear.

  In the upper wall portion 11, a region between the front portion 11f and the rear end portion 11r (hereinafter referred to as “intermediate portion 11m”) is formed in a curved shape that swells upward. Further, in the lower wall portion 12, a region between the front portion 12f and the rear end portion 12r (hereinafter referred to as “intermediate portion 12m”) is formed in a curved shape that swells downward.

  Inside the retainer 10, a flow path for air conditioning air A <b> 1 (hereinafter referred to as “ventilation path 21”) is provided. The ventilation path 21 is a pair of the most upstream common passage 22 connected to the common inlet 14 and a pair of air-conditioning air A1 branched from the common passage 22 and passing through the common passage 22 to the air outlets 15 and 16. Branch passage portions 23 and 24 are provided. The common passage portion 22 is sandwiched between the front portions 11f and 12f.

  Both branch passages 23 and 24 are arranged in the vertical direction. The upper part of the upper branch passage part 23 is constituted by an intermediate part 11m and a rear end part 11r in the upper wall part 11. A lower portion of the lower branch passage portion 24 is constituted by an intermediate portion 12m and a rear end portion 12r in the lower wall portion 12.

  Here, both rear end portions 11r and 12r are inclined as described above. Therefore, the air-conditioning air A1 flows along the rear end portion (the rear end portion 11r of the upper wall portion 11) of the upper branch passage portion 23, so that the flow direction is changed obliquely downward and rearward, so It blows out from the exit 15 in the same direction. Further, the air-conditioning air A1 flows along the rear end portion (the rear end portion 12r of the lower wall portion 12) of the lower branch passage portion 24, so that the flow direction is changed obliquely upward and rearward. Are blown out in the same direction from the blower outlet 16.

  As described above, the air-conditioning air A1 flows into the retainer 10 from the common inlet 14, flows through the ventilation path 21, and then blows out from at least one of the outlets 15 and 16. For this reason, the flow direction of the air-conditioning air A1 corresponds to the longitudinal direction of the vehicle. The front of the vehicle corresponds to the upstream direction of the flow direction of the air-conditioning air A1, and the rear of the vehicle corresponds to the downstream direction of the flow direction.

<Movable panel 30>
The movable panel 30 is for adjusting the amount of the air-conditioning air A1 blown from both the outlets 15 and 16 in order to change the flow direction of the air-conditioning air A1 toward the user. It is formed in a horizontally long shape whose dimension is larger than the dimension in the vertical direction (see FIG. 1).

  As shown in FIGS. 3A and 3B, the movable panel 30 is attached to the retainer 10 so as to be movable in the vertical direction. More specifically, support arms 31 extending forward are respectively connected to both side portions of the movable panel 30 in the vehicle width direction at the rear end portions. A hole 32 is formed in the front end portion of each support arm 31. On the other hand, a support shaft 17 is fixed to the front portion of each side wall portion 13 of the retainer 10. The support shaft 17 is inserted into the hole 32 of each support arm 31. The movable panel 30 is supported by the side wall portions 13 via both support arms 31 and both support shafts 17.

  The movable panel 30 tilts both support arms 31 with both support shafts 17 as fulcrums, thereby closing the upper closing position (see FIG. 4) for closing the entire upper outlet 15 and the lower outlet 16. It is possible to move up and down in a movable region including a lower closing position (see FIG. 5) that closes the whole. Here, in the movable region of the movable panel 30, the center position between the closed positions is referred to as a “neutral (neutral) position”.

  Regardless of the vertical position, the movable panel 30 has a size that can make the sum of the areas (opening areas) where both the air outlets 15 and 16 are actually opened constant. This size is larger than the size of closing the entire upper air outlet 15 when the movable panel 30 is in the upper closed position, and when the movable panel 30 is in the lower closed position, It is larger than the size to block the whole. Further, the size of the movable panel 30 is a size for closing (overlapping) a part of each of the air outlets 15 and 16 when in the neutral position.

<Panel position adjustment mechanism 35>
The panel position adjusting mechanism 35 is a mechanism for adjusting the vertical position of the movable panel 30 and holding the movable panel 30 at that position. Each hole 32 is configured by a long hole extending substantially in the front-rear direction, and each support shaft 17 is movable in the hole 32. The movable panel 30 and the both support arms 31 can move substantially in the front-rear direction through the movement of the support shaft 17 in the hole 32.

  A part of the constituent members of the retainer 10, for example, at least one of the side wall portions 13 is provided with a fixed gear 36 in which a plurality of teeth are arranged in parallel in the vertical direction as a locked portion. Moreover, the movable panel 30 is formed with a movable gear 37 in which a plurality of teeth are juxtaposed in the vertical direction as a locking portion.

  The movable gear 37 meshes with the fixed gear 36 by moving backward (becomes locked). Due to this meshing, the movable gear 37 cannot move in the vertical direction with respect to the retainer 10 via the fixed gear 36. Moreover, the movable gear 37 is released from the meshing state (locked state) with the fixed gear 36 by moving forward.

  Further, a holder 38 is fixed to the front end portion of each side wall portion 13. The holder 38 is formed with a recess 39 that opens on the rear surface. A pressing member 41 is disposed between the holder 38 and the front end portion of the support arm 31 located behind the holder 38. The pressing member 41 includes a rod-shaped portion 42 and a head portion 43 formed at the rear end portion of the rod-shaped portion 42. Many portions of the rod-shaped portion 42 are accommodated in the recess 39. A coil spring 44 as an elastic member is disposed in a compressed state around the rod-shaped portion 42 and between the head 43 and the inner bottom surface of the recess 39. The coil spring 44 always urges the support arm 31 backward via the pressing member 41. The hole 32, the fixed gear 36, the movable gear 37, the holder 38, the pressing member 41, and the coil spring 44 constitute a panel position adjusting mechanism 35.

<Upstream fin 50>
As shown in FIGS. 1 and 2, plate-like upstream fins 50 extending in the vertical direction are disposed at a plurality of positions in front of the movable panel 30 in the retainer 10 and separated from each other in the vehicle width direction. ing. Fin shafts 51 are formed at both upper and lower ends of each upstream fin 50. Each upstream fin 50 is supported by the fin shafts 51 so as to be tiltable on the upper wall portion 11 and the lower wall portion 12 of the retainer 10.

  Connection shafts 52 are respectively provided at two locations separated from each other in the vertical direction at the front portion of each upstream fin 50. The upper connecting shaft 52 for each upstream fin 50 is connected by a connecting rod 53 extending in the vehicle width direction. The lower connecting shaft 52 for each upstream fin 50 is connected by a connecting rod 54 extending in the vehicle width direction. The link shaft 52 and the connecting rods 53 and 54 constitute a link mechanism that tilts all the upstream fins 50 in a synchronized state so as to have the same inclination.

<Operation knob 55>
The operation knob 55 is operated by an occupant, for example, when tilting the upstream fin 50 at the center in the vehicle width direction in order to change the direction in the vehicle width direction of the air-conditioning air A1 blown out from both the outlets 15 and 16. It is a member. The operation knob 55 is attached to the movable panel 30 so as to be slidable in the vehicle width direction. The operation knob 55 is drivingly connected to the upstream fin 50 at the center via a transmission mechanism (not shown). The transmission mechanism is a mechanism for transmitting the sliding movement of the operation knob 55 to the upstream fin 50 at the center, and tilting it with the upper and lower fin shafts 51 as fulcrums. In the transmission mechanism, when the operation knob 55 is located at the center of the movable panel 30 in the vehicle width direction, the upstream fin 50 at the center is substantially parallel to the both side walls 13 of the retainer 10 (see FIG. 1). When the operation knob 55 is slid to the right from the above position, the transmission mechanism tilts the upstream fin 50 with the fin shafts 51 as fulcrums so that the upstream fin 50 is positioned to the right. On the other hand, when the operation knob 55 is slid leftward from the above position, the transmission mechanism tilts the upstream fin 50 with the two fin shafts 51 as fulcrums so that the upstream fin 50 is positioned on the left side toward the downstream side.

<Moving fin 60>
As shown in FIG. 2, the movable fin 60 includes an upper inclined portion 61 and a lower inclined portion 62 and is provided integrally with the movable panel 30. The movable fin 60 is located in front of the central portion of the upstream fin 50 in the retainer 10 in the vertical direction (in front of the movable panel 30) and rearward of the support shaft 17 (see FIG. 3A). ing. The upper inclined portion 61 is inclined so as to become higher toward the rear, and the lower inclined portion 62 is inclined so as to become lower toward the rear. The upper inclined portion 61 and the lower inclined portion 62 are connected to each other at their front end portions. The upper inclined portion 61 constitutes a part of the upper branch passage portion 23, and the lower inclined portion 62 constitutes a part of the lower branch passage portion 24.

  The movable fin 60 tilts with the support shaft 17 as a fulcrum in conjunction with the movable panel 30. The movable fin 60 is deformed so as to narrow the one located on the front side in the moving direction among the branch passage portions 23 and 24 and to expand the one located on the rear side in the moving direction in accordance with the tilting.

<Fixing fin 65>
The fixed fin 65 includes an upper fin portion 66, an intermediate fin portion 67 and a lower fin portion 68, and is fixed to the side wall portion 13 of the retainer 10. The upper fin portion 66 is formed in the upper branch passage portion 23 and in the vicinity of the front of the upper inclined portion 61. Many portions of the upper fin portion 66 are inclined so as to become higher toward the rear. The lower fin portion 68 is formed in the lower branch passage portion 24 and near the front of the lower inclined portion 62. Many portions of the lower fin portion 68 are inclined so as to become lower toward the rear. The lower fin portion 68 is spaced downward from the upper fin portion 66. The intermediate fin portion 67 has a flat plate shape extending in the front-rear direction and the vehicle width direction, and is separated from the upper fin portion 66 and the lower fin portion 68 at the central portion between the upper fin portion 66 and the lower fin portion 68. It is formed with.

<Shut damper 70>
The shut damper 70 is for opening and closing the ventilation path 21 upstream of the fixed fin 65. The shut damper 70 is supported on both side walls 13 of the retainer 10 by a shaft (not shown), and can be tilted between an open position and a closed position. When the shut damper 70 is in the open position, as shown by a solid line in FIG. 2, the shut damper 70 is substantially parallel to the front portions 11 f and 12 f at the substantially central portion in the vertical direction in the upstream portion of the air passage 21. The upstream part of is greatly opened. In the closed position, the shut damper 70 is inclined with respect to both front portions 11f and 12f as shown by a two-dot chain line in FIG.

  As shown in FIG. 1, the air conditioning register includes a damper driving mechanism 71 for opening and closing the shut damper 70. The damper drive mechanism 71 includes an operation dial 72 and a rotation transmission unit (not shown). The operation dial 72 is supported so as to be rotatable with respect to the retainer 10. The rotation transmitting unit is for transmitting the rotation of the operation dial 72 to the shut damper 70, and includes a link mechanism, a gear mechanism, and the like.

Next, the operation of the air conditioning register of the present embodiment configured as described above will be described.
As shown by a two-dot chain line in FIG. 2, when the shut damper 70 is in the closed position, the air conditioning air A <b> 1 is restricted from flowing to the branch passage portions 23 and 24 located downstream from the common passage portion 22, The blowing of air-conditioning air A1 from both outlets 15 and 16 is stopped.

  On the other hand, as shown by the solid line in FIG. 2, when the shut damper 70 is in the open position, the air conditioning air A1 flowing into the common passage portion 22 through the common inlet 14 is divided into an upper side and a lower side of the shut damper 70. Flowing.

  Switching of the shut damper 70 from the closed position to the open position, and switching from the open position to the closed position is performed through a rotation operation of the operation dial 72 in the damper drive mechanism 71. When the operation dial 72 is rotated by an occupant, the rotation is transmitted to the shut damper 70 via a rotation transmitting unit (not shown), and the shut damper 70 is tilted about the shaft.

  In the following description, it is assumed that the shut damper 70 is in the open position. Further, as shown in FIG. 1, the operation knob 55 is at the center position in the vehicle width direction of the movable panel 30, and each upstream fin 50 is in a state parallel to the both side walls 13 of the retainer 10. And

  2 and FIGS. 3A and 3B show air conditioning registers when the movable panel 30 is in the neutral position. At this time, the movable gear 37 to which the urging force of the coil spring 44 is applied via the pressing member 41, the support arm 31 and the movable panel 30 is engaged with and locked to the fixed gear 36 of the retainer 10. Tilt of the support arm 31 with the support shaft 17 as a fulcrum is restricted. The movable panel 30 is restricted from moving in the vertical direction and is held at a neutral position.

  At this time, both the outlets 15 and 16 are opened to the same size. Moreover, the movable fin 60 is located in the center part of the up-down direction. The interval between the upper inclined portion 61 and the upper fin portion 66 is approximately the same as the interval between the lower inclined portion 62 and the lower fin portion 68.

  Many portions of the upper inclined portion 61 are separated in a state substantially parallel to the upper fin portion 66 at the rear of the upper fin portion 66. Further, many portions of the lower inclined portion 62 are separated from the lower fin portion 68 in a state of being substantially parallel to the lower fin portion 68. Further, the front end connecting portions of the upper inclined portion 61 and the lower inclined portion 62 are located in the vicinity of the rear of the intermediate fin portion 67, and the gap between them is the smallest that can be taken.

  Therefore, the air-conditioning air A <b> 1 that has passed above the shut damper 70 is guided to the upper branch passage portion 23. A part of this air-conditioning air A1 flows between the upper fin portion 66 and the intermediate portion 11m of the upper wall portion 11 to be guided to the upper part in the retainer 10, and the remaining portion is the intermediate fin portion 67 and the upper fin. After flowing between the portions 66, it flows along the inclined portion 61 between the upper inclined portion 61 and the upper fin portion 66, thereby being guided to the upper part in the retainer 10. At this time, there is almost no air conditioning air A <b> 1 that passes through the gap between the front end connecting portions of the upper inclined portion 61 and the lower inclined portion 62 and the intermediate fin portion 67. The air-conditioning air A <b> 1 guided to the upper part in the retainer 10 sequentially flows through the upper part of the upstream fin 50 and the rear end part of the branch passage part 23, and then blows out from the upper outlet 15.

  The blowing direction of the air-conditioning air A1 from the upper outlet 15 is determined by the direction in which the rear end portion of the branch passage portion 23 extends, and the rear end of the upper wall portion 11 constituting a part of the rear end portion. The portion 11r is formed in a flat plate shape that is inclined so as to become lower toward the rear. Therefore, by flowing along the rear end portion 11r, the air-conditioning air A1 is blown out from the upper outlet 15 with the flow direction obliquely downward and rearward.

  In addition, the air-conditioning air A1 that has passed below the shut damper 70 is guided to the lower branch passage portion 24. A part of this air-conditioning air A1 flows between the lower fin portion 68 and the intermediate portion 12m of the lower wall portion 12, thereby being led to the lower portion in the retainer 10, and the remaining portion is the intermediate fin portion 67 and the lower fin. After flowing between the portions 68, it flows along the lower inclined portion 62 between the lower inclined portion 62 and the lower fin portion 68, thereby being guided to the lower portion in the retainer 10. At this time, there is almost no air conditioning air A <b> 1 that passes through the gap between the front end connecting portions of the upper inclined portion 61 and the lower inclined portion 62 and the intermediate fin portion 67. Then, the air-conditioning air A1 guided to the lower part in the retainer 10 sequentially flows through the lower part of the upstream fin 50 and the rear end part of the lower branch passage part 24 and then blows out from the lower outlet 16. .

  The amount of air conditioning air A1 blown from the lower air outlet 16 is approximately the same as the amount of air conditioning air A1 blown from the upper air outlet 15. This is because the opening areas of the outlets 15 and 16 are approximately the same.

  The blowing direction of the air-conditioning air A1 from the lower outlet 16 is determined by the direction in which the rear end portion of the lower branch passage 24 extends, and the lower wall portion constituting a part of the rear end portion The rear end 12r of 12 is formed in a flat plate shape that is inclined so as to become higher toward the rear. Therefore, by flowing along the rear end 12r, the air-conditioning air A1 is blown out from the lower outlet 16 with the flow direction obliquely upward and rearward.

  The blowing direction of the air conditioning air A1 from the upper air outlet 15 and the blowing direction of the air conditioning air A1 from the lower air outlet 16 are directions closer to each other toward the downstream. Therefore, both air-conditioning air A1 merges to change the flow direction to an intermediate direction between the flow directions of both air-conditioning air A1. This direction is substantially the same as the direction along the front portion 11 f of the upper wall portion 11 and the front portion 12 f of the lower wall portion 12, that is, the flow direction in the common passage portion 22.

  When the final flow direction of the air-conditioning air A1 toward the occupant is changed diagonally upward, a forward force is applied to the movable panel 30 by pressing the movable panel 30 or the like. This force is transmitted to both support arms 31 connected to the movable panel 30. These movable panel 30 and both support arms 31 are moved forward against the biasing force of the coil spring 44. By this movement, the movable gear 37 is moved forward from the fixed gear 36, and the meshing state (locking state) of both is released.

  When the movable panel 30 is moved upward in a state where the above force is applied to the movable panel 30, both the support arms 31 are tilted upward with the both support shafts 17 as fulcrums. This movable panel 30 closes the upper air outlet 15 more than the lower air outlet 16. In the upper branch passage 23, the air-conditioning air A <b> 1 is more strongly restricted from flowing than in the lower branch passage 24. Accordingly, a larger amount of air-conditioning air A1 flows in the lower branch passage portion 24 than in the upper branch passage portion 23.

  Simultaneously with the above movement of the movable panel 30, the movable fin 60 is tilted upward with the support shaft 17 as a fulcrum in conjunction with the movable panel 30 upstream of the upstream fin 50 in the retainer 10. The upper inclined portion 61 approaches the intermediate portion 11m of the upper wall portion 11, and the lower inclined portion 62 moves away from the intermediate portion 12m of the lower wall portion 12, thereby narrowing the upper branch passage portion 23 and lowering the lower branch portion. The passage portion 24 is expanded.

  The air-conditioning air A1 is more concentrated on the lower branch passage portion 24 where the air outlets 16 are not blocked more than the upper branch passage portion 23 where the air outlets 15 are more often blocked by the movable fins 60. A lot flows. As a result, more air-conditioning air A <b> 1 is guided to the lower outlet 16 than to the upper outlet 15 that is largely blocked by the movable panel 30.

  The blowing direction of the air conditioning air A1 from the upper air outlet 15 and the blowing direction of the air conditioning air A1 from the lower air outlet 16 are directions closer to each other toward the downstream. However, as described above, more air-conditioning air A1 is blown out from the lower air outlet 16 than from the upper air outlet 15. Therefore, the air-conditioning air A1 merges, and is in the middle of the flow direction of the air-conditioning air A1 and is close to the blowing direction from the lower outlet 16 through which the large amount of air-conditioning air A1 flows. Change the flow direction. This direction is a direction along the front portion 11 f of the upper wall portion 11 and the front portion 12 f of the lower wall portion 12, that is, a direction upward from the flow direction in the common passage portion 22.

  FIG. 4 shows the air-conditioning register when the movable panel 30 is moved from the neutral position (FIG. 2) to the upper closed position and no forward force is applied to the movable panel 30. A movable gear 37 on which the urging force of the coil spring 44 acts is engaged with (locked to) the fixed gear 36. Tilt about the support shaft 17 of both support arms 31 is restricted. The movable panel 30 is restricted from moving in the vertical direction and is held at the upper closed position.

  While the entire upper outlet 15 is closed by the movable panel 30, the movable panel 30 does not overlap the lower outlet 16, and the entire outlet 16 is open. In the upper branch passage portion 23, the air-conditioning air A <b> 1 is restricted from flowing, whereas the lower branch passage portion 24 is less susceptible to such restriction.

  Further, when the movable fin 60 is tilted upward in conjunction with the movable panel 30, the upper inclined portion 61 is closest to the intermediate portion 11m of the upper wall portion 11, and the upper branch passage portion 23 is narrowed most. Yes. Further, the lower inclined portion 62 is farthest from the intermediate portion 12m of the lower wall portion 12, and the lower branch passage portion 24 is most expanded. The upper inclined portion 61 is slightly separated rearward from the upper fin portion 66, and the lower inclined portion 62 is significantly separated rearward from the lower fin portion 68.

  Therefore, a part of the air-conditioning air A1 guided to the upper branch passage portion 23 after passing the upper side of the shut damper 70 is the same as the fin between the upper fin portion 66 and the intermediate portion 11m of the upper wall portion 11. It flows along the part 66. Since the upper air outlet 15 is blocked, the air-conditioning air A1 reverses after passing through the rear end portion of the upper fin portion 66, changes the flow direction downward, and the rear end of the upper fin portion 66. Between the upper portion and the upper inclined portion 61, flows obliquely downward and forward along the upper inclined portion 61, and is guided to the lower inclined portion 62.

  In addition, a part of the air-conditioning air A1 guided to the upper branch passage portion 23 passes between the shut damper 70 and the intermediate fin portion 67 and then between the intermediate fin portion 67 and the lower fin portion 68. And is guided to the lower inclined portion 62. A part of the air-conditioning air A1 guided to the upper branch passage portion 23 is guided to the lower inclined portion 62 after passing between the upper fin portion 66 and the intermediate fin portion 67. The air-conditioning air A <b> 1 guided to the lower inclined portion 62 is guided to the lower portion in the retainer 10 by flowing obliquely downward and rearward along the lower inclined portion 62.

  In addition, much of the air-conditioning air A1 that has been passed through the lower side of the shut damper 70 and led to the lower branch passage portion 24 has a lower fin portion as in the case where the movable panel 30 is in the neutral position. By flowing between 68 and the intermediate part 12m of the lower wall part 12, it is guided to the lower part in the retainer 10.

As described above, the air-conditioning air A <b> 1 is gradually changed by 2 degrees by the upper fin portion 66 and the upper inclined portion 61 in the process of being guided to the lower portion in the retainer 10.
Then, the air-conditioning air A1 guided to the lower part in the retainer 10 sequentially flows through the lower part of the upstream fin 50 and the rear end part of the lower branch passage part 24 and then blows out from the lower outlet 16. . On the other hand, the air-conditioning air A1 is not blown out from the upper outlet 15. Therefore, the air-conditioning air A <b> 1 that is blown out from the lower air outlet 16 and goes obliquely upward and rearward reaches the occupant.

  As described above, the phenomenon in which the air-conditioning air A1 flows along each part of the fixed fin 65, each part of the movable fin 60, and further along the rear end part 12r is due to the Coanda effect. The Coanda effect is the property of a fluid that attempts to flow along an object when a substance is placed in the flow.

  When returning the flow direction of the air-conditioning air A <b> 1 toward the occupant to the neutral direction described above, a forward force is applied to the movable panel 30, so that the movable gear 37 is engaged with the fixed gear 36. Is stopped. In this state, both support arms 31 are tilted downward with both support shafts 17 as fulcrums, so that the movable panel 30 is moved to the neutral position, and the interior of the air conditioning register is shown in FIGS. 2 and 3A. Return to state.

  Note that when the movable panel 30 is moved downward from the neutral position, an operation reverse to the above is performed. When the movable panel 30 is moved to the lower closing position, the air conditioning register is in the state shown in FIG. The entire lower outlet 16 is closed by the movable panel 30, and the movable fin 60 is inclined in the direction opposite to that in FIG. As a result, the air-conditioning air A1 flows as shown by the arrows in FIG. 5, and after being guided to the upper part in the retainer 10, the upper part of the upstream fin 50 and the rear end part of the upper branch passage part 23 are sequentially arranged. After flowing, the air is blown out from the upper air outlet 15. On the other hand, air-conditioning air A1 is not blown out from the lower outlet 16. Therefore, the air-conditioning air A <b> 1 that is blown out from the upper air outlet 15 and goes diagonally downward and rearward reaches the occupant.

  As described above, depending on the position of the movable panel 30, the flow direction of the air conditioning air A <b> 1 that finally faces the passenger is changed. Constant regardless of position. In addition, the branch passage portions 23 and 24 are not provided with a member corresponding to a fin for changing the flow direction of the air-conditioning air A1 in the vertical direction, that is, a member serving as ventilation resistance. For this reason, there is little fluctuation in the pressure loss caused by the change in the flow direction of the air-conditioning air A1.

In addition, since the sum of the opening areas of both the outlets 15 and 16 is the same as or close to the opening area of the common inlet 14, the pressure loss is small regardless of the flow direction of the air conditioning air A1.
By the way, when the operation knob 55 at the center position in the vehicle width direction is slid to the right or left along the movable panel 30, the sliding movement is caused by the upstream fin in the center portion in the vehicle width direction via the transmission mechanism. 50. The upstream fin 50 is tilted in the same direction as the sliding direction of the operation knob 55 with both fin shafts 51 as fulcrums. The tilt of the upstream fin 50 is transmitted to the other upstream fins 50 via the link mechanism, and the upstream fins in the central part are inclined in the same tendency as the upstream fins 50 in the central part. It is tilted in synchronization with 50. The air-conditioning air A <b> 1 flows along the tilted upstream fins 50, and is thus blown out of the outlets 15 and 16 that are not completely closed (opened) by the movable panel 30.

According to the embodiment described in detail above, the following effects can be obtained.
(1) As the retainer 10, one having a common inlet 14 for air-conditioning air A1 at one end and a pair of outlets 15 and 16 arranged in parallel in a state separated from each other in the vertical direction is used. The ventilation path 21 in the retainer 10 is configured by a common passage portion 22 at the most upstream portion and a pair of upper and lower branch passage portions 23 and 24 branched from the common passage portion 22.

  The distance between the downstream end portion (rear end portion) in the flow direction of the air-conditioning air A1 and the downstream end portion (rear end portion) of the other branch passage portion 24, 23 is downstream of each branch passage portion 23, 24. It is formed so as to become narrower. In the retainer 10, the sum of the opening areas of both the air outlets 15 and 16 is constant in a movable region including a closed position for closing the entire outlet 15 and a closed position for closing the entire outlet 16. A movable panel 30 is provided (FIG. 2).

  For this reason, it is possible to suppress fluctuations in pressure loss caused by a change in the flow direction of the air-conditioning air A1. The air-conditioning air A1 can be efficiently blown out regardless of the blowing direction.

  (2) A plate-like upstream fin 50 extending in the juxtaposed direction (vertical direction) of the air outlets 15 and 16 is disposed upstream (frontward) of the movable panel 30 in the retainer 10. , And can be tilted in a direction (vehicle width direction) perpendicular to the juxtaposed direction (FIG. 2).

  Therefore, by tilting the upstream fin 50, the direction of the air conditioning air A1 can be changed, and the blowing direction of the air conditioning air A1 in the direction (vehicle width direction) orthogonal to the parallel arrangement direction can be changed.

  (3) A direction (vehicle width direction) perpendicular to the juxtaposed direction (vertical direction) of the air outlets 15 and 16 is provided on the movable panel 30 by drivingly connecting the operation knob 55 to the upstream fin 50 via a transmission mechanism. (FIGS. 1 and 2).

Therefore, by sliding the operation knob 55 along the movable panel 30, the upstream fin 50 can be tilted to obtain the effect (2).
(4) A movable fin 60 that constitutes a part of each of the branch passage portions 23 and 24 and tilts in conjunction with the movable panel 30 is provided upstream of the upstream fin 50 in the retainer 10 (FIG. 4). FIG. 5).

  Therefore, the movable fin 60 is tilted in conjunction with the movable panel 30 to narrow the branch passage portions 23 and 24 that are positioned forward in the moving direction of the movable panel 30 and to expand those that are positioned rearward in the moving direction. Can do. Of the air outlets 15 and 16, more air-conditioning air A <b> 1 can be guided to those that are not so than those that are largely blocked by the movable panel 30.

  Further, the air conditioning air A1 is directed toward the rear end portions (rear end portions 11r, 12r) of the branch passage portions 23, 24 having the outlets 15, 16 that are not largely blocked by the movable panel 30. Many air-conditioning air A1 can be made to flow along the rear end portion, and the directivity of the air-conditioning air A1 can be further enhanced.

  (5) A support arm 31 that extends toward the upstream (front) in the flow direction of the air-conditioning air A1 is coupled to the movable panel 30. The support arm 31 is supported by the support shaft 17 so as to be tiltable with respect to the side wall portion 13 of the retainer 10 at least in the direction in which the air outlets 15 and 16 are arranged in parallel (vertical direction). And the movable fin 60 is integrally provided in this movable panel 30 (FIG. 3 (a), (b)).

Therefore, by moving the movable panel 30, the movable fin 60 can be tilted to obtain the effect (4).
(6) The fixed fin 65 is provided in the ventilation path 21 upstream (frontward) of the movable fin 60 (FIGS. 4 and 5).

  Therefore, by changing the flow direction of the air-conditioning air A1 little by little in each of the fixed fin 65 and the movable fin 60, it is possible to suppress a sudden change in the flow direction.

  (7) The support arm 31 is supported by the both support shafts 17 so as to be tiltable and movable in the flow direction (front-rear direction) of the air-conditioning air A1 with respect to the side wall portions 13 of the retainer 10. A locked portion (fixed gear 36) is provided on at least one side wall portion 13 of the retainer 10. The movable panel 30 is locked to the locked portion (fixed gear 36) by moving to one side (rearward) in the flow direction, and is engaged by moving to the other (front) in the flow direction. A locking portion (movable gear 37) that releases the locking state with the locking portion (fixed gear 36) is provided. Between the retainer 10 and the support arm 31, an elastic member that urges the support arm 31 in a direction (rearward) in which the locking portion (movable gear 37) is locked to the locked portion (fixed gear 36). A coil spring 44) is provided (FIGS. 3A and 3B).

  Therefore, the tilting of the support arm 31 is restricted by the locking of the locking portion (movable gear 37) with the locked portion (fixed gear 36), and the movable panel 30 is arranged in the direction in which the outlets 15 and 16 are arranged side by side. It can be held at that position in the (vertical direction).

  Moreover, the locked state with the to-be-latched part (fixed gear 36) of the latching | locking part (movable gear 37) is cancelled | released by applying the force which goes to the direction (front) which resists urging | biasing force with respect to the movable panel 30. Then, the movable panel 30 can be moved in the juxtaposed direction (vertical direction). Further, by stopping applying the force to the movable panel 30, the locking portion (movable gear 37) can be locked again to the locked portion (fixed gear 36).

  Further, since the structure in which the movable gear 37 is meshed with the fixed gear 36 is adopted, the position of the movable panel 30 in the direction in which the air outlets 15 and 16 are juxtaposed (vertical direction) can be finely adjusted by changing the meshing position. Can do.

In addition, the said embodiment can also be implemented as a modification which changed this as follows.
A functional component may be attached to the movable panel 30 by utilizing the fact that the movable panel 30 has a wide and narrow surface in the vehicle width direction. For example, a display, a switch, a lighting fixture, or the like that displays information related to air conditioning may be attached to the movable panel 30 as a functional component. Moreover, the movable panel 30 may be decorated by attaching components other than the functional components to the movable panel 30.

  As a structure for supporting the movable panel 30 so as to be movable in the flow direction (front-rear direction) of the air-conditioning air A1 with respect to the retainer 10 via the support shaft 17, the support shaft 17 is opposite to the above embodiment. May be fixed to the support arm 31, the hole 32 may be provided in the side wall portion 13 of the retainer 10, and the support shaft 17 may be inserted into the hole 32. In this case, it is desirable for the hole 32 to have a shape that does not penetrate the side wall portion 13, that is, a concave portion, in order to suppress wind leakage.

  A type different from a coil spring as an elastic member, provided that the support arm 31 is urged in a direction in which the locking portion (movable gear 37) is locked to the locked portion (fixed gear 36). A spring having a form different from that of the spring may be employed.

Further, the urging may be performed by pushing the support arm 31 as in the above embodiment, or may be performed by pulling.
The condition is that the movable panel 30 is locked to each other by being moved in one direction of the air-conditioning air A1, and is released from the above-mentioned locked state by being moved to the other direction in the same flow direction. The locking portion may be changed to a different one from the movable gear 37, and the locked portion may be changed to a different one from the fixed gear 36.

The locking portion (movable gear 37) may be provided on the support arm 31 instead of the movable panel 30, or may be provided across both the movable panel 30 and the support arm 31.
