Description

register

The present invention relates to an air outlet adjustment register used for an air outlet of an air conditioner such as an automobile, and more particularly to a register having an air outlet that is long in the longitudinal direction and short in the lateral direction and inclined in the lateral direction.

As a register for air blowing adjustment used for air outlets for air conditioning of automobiles, etc., a laterally movable louver and a longitudinally movable louver are arranged in a bezel or retainer that forms a ventilation path, and the bezel is moved back and forth in the orthogonal direction. When air is blown out from an air outlet provided in the air-conditioner, a register that adjusts the air blowing direction up, down, left and right by changing the angle of each fin of the horizontally movable louver and vertically movable louver is generally used in an air conditioner of an automobile, etc. ing.

As this type of register, there is mainly a register having a rectangular air outlet that is long in the longitudinal direction and short in the lateral direction, and provided with a few movable fins on the inside of the air outlet. In some cases, it is installed in the interior of an automobile due to design and design demands (see, for example, Patent Document 1).

JP 2002-103954 A Japanese Patent Laid-Open No. 2004-210111

On the other hand, registers used for air conditioning in automobiles are usually installed with an opening in front of the instrument panel, but the position of the register is a dash in relation to the display, operation panel, etc. installed there. It may be placed on the top of the instrument panel near the board. For example, when a register is placed near the dashboard at the top of the instrument panel, the air outlet of the register is retracted to the upstream side so that it matches the inclined surface of the top of the dashboard at the top of the instrument panel. The lower portion is formed in an inclined shape projecting downstream (see, for example, Patent Document 2).

Such a resistor has an air outlet that is long in the longitudinal direction and short in the lateral direction and inclined in the lateral direction. The air outlet may be inclined at the front of the register, that is, depending on the total design. In some cases, the inclination angle of the outlet with respect to the vertical plane increases (the inclination angle with respect to the horizontal plane decreases).

However, in a register in which the front surface of the elongated air outlet is inclined in the short direction and the inclination is large, when the front fin is swung to the inclined side (downward), the lower air flow is Since it is blown straight out along the lower wall, it interferes with the air flow going diagonally downward, and the directivity of the wind during lower air blowing tends to deteriorate, and the inclination angle of the front surface of the air outlet is large Indeed, there was a problem that the directivity of the downward blowing deteriorated.

The present invention solves the above-mentioned problems, and in a register having an air outlet that is long in the longitudinal direction and short in the lateral direction and inclined in the lateral direction, the front movable louver is disposed on the inclined side of the air outlet. An object of the present invention is to provide a register that can improve the directivity of wind when shaken.

The register according to the present invention has an elongated air outlet that is long in the horizontal horizontal direction and short in the vertical and vertical directions, and a front movable louver is disposed along the horizontal horizontal direction at an inner front portion of the air outlet, In the register formed such that the air outlet is inclined so that the upper part is retreated to the upstream side and the lower part is projected to the downstream side,
The front movable louver pivotally supports one central lateral fin at a substantially vertical center inside the air outlet so as to be pivotable in the horizontal lateral direction, and a storage recess provided on the upper wall surface inside the air outlet. The upper auxiliary horizontal fin is pivotally supported so as to be retractable and rotatable in the horizontal horizontal direction, and the lower auxiliary horizontal fin can be stored in a storage recess provided in the lower wall surface inside the air outlet. It is configured to be pivotally supported in the direction of the direction,
The central lateral fin is pivotally supported by pivots projecting on both sides, and the upper auxiliary horizontal fin and the lower auxiliary horizontal fin are formed with one surface as a bulging curved surface and the other surface as a flat surface. , Is pivotally supported so as to protrude toward the flow path side and turn,
When the central horizontal fin is swung downward, the upper auxiliary horizontal fin rotates so that the flat surface is substantially parallel to the central horizontal fin, and the lower auxiliary horizontal fin is upstream of the bulging curved surface. When the central lateral fin is swung upward, the lower auxiliary lateral fin is pivoted so that the flat surface is substantially parallel to the central lateral fin, The upper auxiliary lateral fin rotates so that the bulging curved surface faces the upstream side and protrudes toward the flow path side.

Here, the upstream side and the downstream side mean the upstream side or the downstream side of the air flow flowing through the flow path, and in each member, the front part means the downstream part and the rear part means the upstream part.

According to the present invention, when the front movable louver is swung downward, the central horizontal fin faces obliquely downward, the flat surface of the upper auxiliary horizontal fin is substantially parallel to the central horizontal fin, and the upper auxiliary horizontal fin Since the downstream end rotates so as to protrude toward the flow path, the air flow well guided by the fin from between the upper auxiliary lateral fin and the central lateral fin can be blown downward. Further, at this time, the air flow that passes through the lower side of the central horizontal fin and goes straight forward is blocked by the lower auxiliary horizontal fin, and the bulging curved surface of the lower auxiliary horizontal fin approaches the flow path side toward the upstream side. Thus, the lower auxiliary horizontal fin rotates so that the air flow passing through the lower part of the flow path is pressed against the central horizontal fin side by the bulging curved surface of the lower auxiliary horizontal fin. The directivity of can be greatly improved.

When the front movable louver is swung upward, the central lateral fin faces obliquely upward, the flat surface of the lower auxiliary horizontal fin is substantially parallel to the central horizontal fin, and the downstream end of the lower auxiliary horizontal fin is on the flow path side. Therefore, the air flow well guided by the fin can be blown upward from between the lower auxiliary lateral fin and the central lateral fin. Further, the air flow that passes straight above the central lateral fin and advances straight forward is blocked by the upper auxiliary horizontal fin, and rotates so that the bulging curved surface of the upper auxiliary horizontal fin projects toward the flow path side toward the upstream side. Therefore, the air flow passing through the upper portion of the flow path is pressed against the central horizontal fin side by the bulging curved surface of the upper auxiliary horizontal fin, and thereby, the directivity of the upward air blowing toward the central horizontal fin can be improved. .

Here, it is preferable that the central lateral fin is pivotally supported by pivots protruding from the downstream end portions on both sides. According to this, the portion where the front end portion of the central horizontal fin protrudes in front of the air outlet of the bezel is reduced, and the deterioration of the design of the register front due to the protrusion of the central horizontal fin can be prevented, and the central horizontal fin is slid. The operability of the operation knob provided to be movable can be improved.

Further, the support shafts of the lower auxiliary horizontal fin and the upper auxiliary horizontal fin of the front movable louver are configured as a shift support shaft through the arm portion, and the lower auxiliary horizontal fin and the upper auxiliary horizontal fin are offset to the outside of the fin body. It is preferable to have a structure that rotates around the shifted support shaft. According to this, with a simple structure, the lower auxiliary horizontal fin and the upper auxiliary horizontal fin can be operated so as to protrude in accordance with the rotation of the central horizontal fin.

Further, it is preferable that the shift support shafts of the lower auxiliary horizontal fin and the upper auxiliary horizontal fin are located in the flow path upstream of the support shaft of the central horizontal fin. Furthermore, it is preferable that the shift support shaft of the upper auxiliary horizontal fin is located in the flow path upstream from the shift support shaft of the lower auxiliary horizontal fin. According to this, it is possible to improve the directivity of blowing when the central lateral fin is shaken up or down.

Further, a fin rotation mechanism is linked to the support shaft of the central horizontal fin, the lower auxiliary horizontal fin and the upper support horizontal fin of the front movable louver, and the fin rotation mechanism is connected to the central horizontal fin. When rotating downward, the upper auxiliary horizontal fin is rotated in the same direction as the central horizontal fin by the same angle, and the lower auxiliary horizontal fin is rotated in the same direction as the central horizontal fin at a larger angle than the central horizontal fin. When the center horizontal fin is rotated upward, the lower auxiliary horizontal fin is rotated by the same angle in the same direction as the central horizontal fin, and the upper auxiliary horizontal fin is moved in the same direction as the central horizontal fin. It can be configured to rotate at an angle greater than the central lateral fin.

Here, the fin rotation mechanism is disposed on a side portion of the retainer so as to be vertically reciprocable, and has a cam member provided with respective cam grooves for the central horizontal fin, the lower auxiliary horizontal fin, and the upper auxiliary horizontal fin. A cam roll for engaging with each cam groove, and the cam roll for the central lateral fin is connected to the support shaft of the central lateral fin via an arm, and the cam roll for the lower auxiliary lateral fin Is connected to the shift support shaft of the lower auxiliary horizontal fin via the arm, and the cam roll for the upper auxiliary horizontal fin is connected to the shift support shaft of the upper auxiliary horizontal fin via the arm. Can do.

According to this, the fin rotation mechanism can be configured relatively easily, and the lower auxiliary horizontal fin and the upper auxiliary horizontal fin are each rotated by a predetermined angle in accordance with the vertical rotation operation of the central horizontal fin. be able to.

On the other hand, the register of another invention has an elongated air outlet that is long in the vertical direction and short in the horizontal direction, and a front movable louver is arranged along the vertical direction inside the air outlet. The front movable louver has one central vertical fin in the register formed such that the air outlet is inclined so that one side is retracted to the upstream side and the other side is protruded to the downstream side. While being pivotally supported in the center of the left and right sides inside the air outlet so as to be pivotable in the vertical and vertical directions, the retractable auxiliary vertical fin can be stored in the storage recess provided on the side wall of the retractable side inside the air outlet. Further, it is pivotally supported so as to be rotatable in the vertical and vertical directions, and is rotated in the vertical and vertical directions so that the protruding auxiliary vertical fin can be stored in a storage recess provided on the side wall surface on the protruding side inside the air outlet. The center vertical fin is horizontally supported by the upper and lower support shafts. The retreat-side auxiliary vertical fin and the protrusion-side auxiliary vertical fin are formed so that one surface is a bulging curved surface and the other surface is a flat surface, and the shaft is supported so as to be able to rotate toward the channel side. When the central vertical fin is swung to the protruding side, the backward auxiliary vertical fin rotates so that the flat surface is substantially parallel to the central vertical fin, and the protruding auxiliary vertical fin is When the center vertical fin is swung toward the retreat side, the flat surface of the protruding side auxiliary vertical fin is substantially parallel to the central vertical fin when the center vertical fin is swung toward the retreat side. The backward auxiliary vertical fin is rotated so that the bulging curved surface faces the upstream side and protrudes toward the flow path side.

According to the present invention, when the front movable louver is swung to the oblique left and right protruding side of the air outlet, the central vertical fin faces the oblique protruding side, and the flat surface of the backward auxiliary vertical fin is the central vertical fin. And the downstream end of the backward auxiliary vertical fin rotates so as to protrude toward the flow path side, so that it is well guided by the fin from between the backward auxiliary vertical fin and the central vertical fin. The air flow can be blown with good directivity to the obliquely protruding side of the air outlet.

Further, at this time, the air flow passing through the protruding side of the central vertical fin and going straight forward is blocked by the protruding auxiliary vertical fin, and the bulging curved surface of the protruding auxiliary vertical fin faces the upstream side toward the upstream side. Since the protrusion side auxiliary vertical fin rotates so as to squeeze out, the air flow passing through the protrusion side of the flow path is pressed against the center vertical fin side by the bulging curved surface of the protrusion side auxiliary vertical fin. It is possible to greatly improve the directivity of air blowing toward the protruding side where the vertical fins face.

In addition, when the front movable louver is swung to the backward side of the air outlet in the diagonally left-right direction, the central vertical fin faces the diagonally backward side, and the flat surface of the protruding side auxiliary vertical fin is substantially parallel to the central vertical fin and protrudes. Since the downstream end of the side auxiliary vertical fin rotates so as to protrude toward the flow path side, an air flow well guided by the fin from between the protruding side auxiliary vertical fin and the central horizontal fin The air can be blown with good directivity toward the obliquely backward side. Also, at this time, the air flow that passes through the retreating side of the central vertical fin and goes straight forward is blocked by the retreating auxiliary vertical fin, and the bulging curved surface of the retreating auxiliary vertical fin approaches the flow path side toward the upstream side. Since the air flow passing through the retreating side of the flow path is pressed against the central vertical fin side by the bulging curved surface of the retreating side auxiliary vertical fin, this causes the retreating side toward the central vertical fin to The directivity of ventilation can be improved.

Here, it is preferable that the central vertical fin is pivotally supported by pivots protruding from the downstream end portions on both sides. According to this, the portion where the front end portion of the central vertical fin protrudes forward of the air outlet of the bezel is reduced, and deterioration of the design of the register front surface due to the protrusion of the central vertical fin can be prevented. The operability of the operation knob provided to be movable can be improved.

Further, the support shafts of the protrusion side auxiliary vertical fin and the retreat side auxiliary vertical fin of the front movable louver are configured as a shift support shaft through an arm portion, and the protrusion side auxiliary vertical fin and the reverse side auxiliary vertical fin are fin bodies. It is preferable to have a structure that rotates around a shift support shaft shifted outward.

Further, it is preferable that the shift support shafts of the projecting side auxiliary vertical fin and the retreat side auxiliary vertical fin are located in the flow path upstream of the support shaft of the central vertical fin.

Further, a fin rotating mechanism is linked to the supporting shaft of the central vertical fin of the front movable louver, the shift supporting shaft of the protruding auxiliary vertical fin and the backward auxiliary vertical fin, and the fin rotating mechanism is connected to the central vertical fin. When the fin is rotated to the protruding side, the backward auxiliary vertical fin is rotated in the same direction as the central vertical fin by the same angle, and the protruding auxiliary vertical fin is rotated in the same direction as the central vertical fin. When turning the central vertical fin to the retreat side, rotate the protrusion side auxiliary vertical fin by the same angle in the same direction as the central vertical fin, It can be configured to rotate in the same direction as the central vertical fin at an angle larger than that of the central vertical fin.

According to the register of the present invention, when the front movable fin is swung to the inclined side of the air outlet, even if the register has an air outlet that is long in the longitudinal direction and short in the lateral direction and inclined in the lateral direction. The directivity of wind can be improved.

Each vertical fin 4a has a support shaft 4b projecting from the upper and lower portions, and the upper and lower support shafts 4b are supported by bearings provided on the upper and lower walls of the flow path 5, and are supported so as to be able to rotate left and right. ing.

As shown in FIGS. 2 and 3, an operation knob 19 is externally fitted to the central lateral fin 7 so as to be slidable in the left-right longitudinal direction, and the central lateral fin 7 is rotated up and down by holding the operation knob 19. By making the operation knob 19 slid in the left-right direction, the rear movable louver 4 is swung left and right to change the wind direction to the left and right.

For this purpose, as shown in FIG. 3, a rack portion 18a is provided at the rear portion of the operation knob 19 as a linking portion, and a fan-like gear portion 18b is provided on one vertical fin 4a of the rear movable louver 4. When the operation knob 19 is slide-operated when the gear 18a is engaged with the gear 18b, the vertical fin 4a rotates. Further, crank shafts (not shown) are pivotally attached to the support shafts 4b of all the vertical fins 4a including the vertical fins 4a, and the crank shafts of the respective crank portions are connected to each other by one link bar. As a result, when the operation knob 19 is slid left and right on the central horizontal fin 7, the vertical fins 4a of the rear movable louver 4 are pivoted to the left and right to adjust the wind direction to the left and right.

The central lateral fin 7 is pivotally supported by pivots 7a projecting from the downstream end portions on both sides thereof. The central horizontal fin 7 is rotated in the vertical direction by holding an operation knob 19 fitted on the central horizontal fin 7. The front end (downstream end) of the central horizontal fin 7 is in front of the air outlet 17 of the bezel 1. Since there are not a few protruding portions, the design of the register front surface due to the protrusion of the central horizontal fin 7 is good, and the operability when the central horizontal fin 7 is turned up and down with the operation knob 19 is also good.

Next, the operation of the register having the above configuration will be described with reference to FIGS. 2 and 7 to 10. FIG. The register is attached to an instrument panel or a dashboard portion in an automobile by connecting a back side air inlet to a ventilation duct (not shown). The resistor air outlet 17 is exposed to the front of the instrument panel or dashboard, but the upper part of the air outlet 17 is inclined so that the upper part is retracted upstream and the lower part protrudes downstream. Design can be adjusted to the inclined shape of the panel or dashboard. In addition, since the air outlet 17 has a simple design that is elongated to the left and right and thin to the top and bottom, it does not adversely affect the design of the display or operation panel provided on the instrument panel or dashboard. Can be improved.

When the air is blown straight in front of the register, the central lateral fin 7 of the front movable louver 3 is in a horizontal state, that is, a state facing straight forward as shown in FIG. In this state, the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9 are both kept horizontal and are stored in the storage recesses 6 a and 6 b on the upper wall surface and the lower wall surface of the flow path 5. Therefore, the airflow flowing through the flow path 5 is blown with very little pressure loss in the horizontal front direction toward the central lateral fin 7 without receiving almost any air resistance by the upper auxiliary horizontal fin 8 and the lower auxiliary horizontal fin 9. The Thereby, the pressure loss at the time of level adjustment can be reduced as compared with a register in which three normal horizontal fins are arranged in parallel with the air outlet.

On the other hand, when the central lateral fin 7 is in the horizontal state as described above, the operation knob 19 is operated so that the central lateral fin 7 is inclined downward (for example, about 30 ° with respect to the horizontal plane) as shown in FIGS. When rotated, the upper auxiliary horizontal fin 8 is rotated by the same angle (about 30 °) in the same direction as the central horizontal fin 7 by the action of the fin rotating mechanism 10, and the flat surface 85 is rotated by the central horizontal fin 7. The lower auxiliary horizontal fin 9 rotates about 90 ° in the same direction as the central horizontal fin 7 and rotates so as to protrude vertically into the flow path 5.

Thereby, as shown in FIG. 7, the air flow flowing from the flow path 5 toward the air outlet 17 is the air flow flowing from the center of the flow path 5 to the upper auxiliary horizontal fin 8 and the central horizontal fin 7. The air is blown diagonally downward from the air outlet 17 toward the central horizontal fin 7 by the fin guide. Further, the airflow flowing through the lower part of the flow path 5 hits the lower part of the flow path 5 and hits the bulging curved surface 94 of the lower auxiliary horizontal fin 9 in a vertical state, and is collected in the vicinity of the central horizontal fin 7. The air flow passing through the lower side of the central lateral fin 7 and going straight forward is blocked by the lower auxiliary lateral fin 9. As a result, the lower air flow collected in the vicinity of the central lateral fin 7 flows so as to be pressed against the lower surface of the central lateral fin 7, and is guided by the central lateral fin 7 and blown obliquely downward. .

On the other hand, when the operation knob 19 is operated to rotate the central lateral fin 7 obliquely upward (for example, about 30 ° with respect to the horizontal plane) as shown in FIG. The fin 9 is rotated in the same direction as the central lateral fin 7 by the same angle (about 30 °), the flat surface 95 is parallel to the central lateral fin 7, and the upper auxiliary lateral fin 8 is in the same direction as the central lateral fin 7. It rotates about 90 ° so as to protrude vertically into the flow path 5.

Thereby, as shown in FIG. 8, the air flow flowing from the flow path 5 toward the air outlet 17 is the flow of air flowing from the center to the lower part of the flow path 5 between the lower auxiliary horizontal fin 9 and the central horizontal fin 7. The air is guided by the fins through the gaps and the like, and is blown from the air outlet 17 obliquely upward toward the central lateral fin 7. Further, the airflow flowing through the upper part of the flow path 5 approaches the upper part of the flow path 5, hits the bulging curved surface 84 of the upper auxiliary horizontal fin 8 in a vertical state, and flows so as to be collected in the vicinity of the central horizontal fin 7. For this reason, the air flow that passes through the upper side of the central lateral fin 7 and goes straight forward is blocked by the upper auxiliary lateral fin 8, and the upper air flow collected in the vicinity of the central lateral fin 7 The air flows so as to be pressed against the upper surface, and is blown obliquely upward by the guide of the central lateral fin 7.

In this way, when the front movable louver 3 is swung downward, the central lateral fin 7 faces obliquely downward, and the flat surface 85 of the upper auxiliary lateral fin 8 is substantially parallel to the central lateral fin 7 and the upper auxiliary Since the horizontal fin 8 rotates so as to protrude toward the flow path 5, the air flow well guided by the fin is blown downward from between the upper auxiliary horizontal fin 8 and the central horizontal fin 7. Can do. At this time, the air flow passing through the lower side of the central horizontal fin 7 and traveling straight forward is blocked by the lower auxiliary horizontal fin 9 and the bulging curved surface 94 of the lower auxiliary horizontal fin 9 flows toward the upstream side. Since the lower auxiliary horizontal fin 9 rotates so as to protrude toward the road, the air flow passing through the lower portion of the flow path 5 acts so as to be pressed against the central horizontal fin 7 side by the bulging curved surface 94 of the lower auxiliary horizontal fin 9. To do. For this reason, the directivity of the ventilation to the downward direction which the center horizontal fin 7 faces can be improved greatly.

That is, when the air outlet 17 inclines so that the lower part of the air outlet 17 protrudes forward and the upper part recedes backward, in the conventional register, the air flow that flows straight in the horizontal direction below the flow path 5 However, in this front movable louver 3, the lower auxiliary horizontal fin 9 causes the air flow that passes through the lower part of the flow path 5 to flow toward the central horizontal fin 7 side. Therefore, the directivity of the downward air blowing is greatly improved.

On the other hand, when the front movable louver 3 is swung upward, the central horizontal fin 7 faces obliquely upward, the flat surface 95 of the lower auxiliary horizontal fin 9 is substantially parallel to the central horizontal fin 7, and the lower auxiliary horizontal fin 9 flows. Since it rotates so that it may protrude toward the path | route 5, the air flow favorably guided by the fin from between the lower auxiliary horizontal fin 9 and the central horizontal fin 7 can be blown upward. At this time, the air flow passing through the upper side of the central horizontal fin 7 and going straight forward is blocked by the upper auxiliary horizontal fin 8, and the bulging curved surface 84 of the upper auxiliary horizontal fin 8 is directed toward the upstream side. The air flow passing through the upper portion of the flow path 5 acts so as to be pressed against the central lateral fin 7 side by the bulging curved surface 84 of the upper auxiliary lateral fin 8, thereby The directivity of the ventilation to the can be improved.

Next, the operation of the register having the above configuration will be described with reference to FIGS. 12 to 14. When air is blown straight toward the front, the central vertical fin 27 of the front movable louver 23 is straight as shown in FIG. Make it look forward. In this state, both the backward auxiliary vertical fin 28 and the protruding auxiliary vertical fin 29 are kept parallel to the flow path 35 and are stored in the storage recesses 6 a and 6 b on the side wall surface of the flow path 35. Therefore, the air flow flowing through the flow path 35 is blown with a very small pressure loss in front of the central vertical fin 27 with almost no air resistance due to the backward auxiliary vertical fin 28 and the protruding auxiliary vertical fin 29. The Thereby, a pressure loss can be reduced compared with the register | resistor which arranged three horizontal fins in parallel with the air blower outlet.

On the other hand, when the operation knob 26 is operated to rotate the central vertical fin 27 to the projecting side of the air outlet 25 by, for example, about 30 ° as shown in FIG. The vertical fin 28 rotates by the same angle (about 30 °) in the same direction as the central vertical fin 27, and the flat surface 285 of the fin becomes parallel to the central vertical fin 27. Further, the protrusion-side auxiliary vertical fin 29 rotates by 90 ° in the same direction as the central vertical fin 27 and rotates so as to protrude vertically into the flow path 35.

Thereby, as shown in FIG. 13, the air flow flowing from the flow path 35 toward the air outlet 25 flows toward the right side wall from the center of the flow path 35. Guided by the fins 27, the air is blown from the air outlets 25 to the left obliquely. In addition, the airflow that flows near the left side wall of the flow path 35 hits the left side of the flow path 35 and hits the bulging curved surface 294 of the protruding auxiliary vertical fin 29 in a vertical state, and is collected in the vicinity of the central vertical fin 27. . As a result, the air flow that passes through the left side of the central vertical fin 27 and goes straight forward is blocked by the protruding auxiliary vertical fin 29.

Therefore, the air flow toward the left along the central vertical fin 27 is not adversely affected by the straight air flow, and the air flow collected in the vicinity of the central vertical fin 27 is the left side surface of the central vertical fin 27. Then, the airflow is blown with good directivity toward the left diagonal direction because the airflow is advanced along the central vertical fin 27.

As described above, when the front movable louver 23 is swung to the left side, that is, the projecting side of the air outlet 25, the central vertical fin 27 is directed obliquely to the left, and the flat surface 285 of the reverse auxiliary vertical fin 28 is centrally vertical. Since the protrusion-side auxiliary vertical fin 29 is rotated substantially in parallel with the fin 27 and protrudes toward the flow path 35, the air flow blown straight along the wall surface on the protrusion side is blocked and leftward The airflow that is well guided by the fins between the retreat-side auxiliary vertical fins 28 and the central vertical fins 27 does not deteriorate the directivity when hitting the airflow that goes to the left of the protruding air outlet 25 It can blow with good directivity.

On the other hand, as shown in FIG. 14, when the operation knob 26 is operated to rotate the central vertical fin 27 to the retreat side of the air outlet 25 (the right side toward the register front), the operation of the fin rotation mechanism 10 is performed. The protrusion-side auxiliary vertical fin 29 is rotated in the same direction as the central vertical fin 27 by the same angle (about 30 °). The retreat-side auxiliary vertical fin 28 rotates in an angle (about 90 °) larger than the central vertical fin 27 in the same direction as the central vertical fin 27, and is vertical so as to push the bulging curved surface 294 toward the upstream side of the flow path 35. It will be in a state to turn to.

Thereby, as shown in FIG. 14, the air flow flowing from the flow path 35 toward the air outlet 25 is the air flow flowing toward the left side wall from the center of the flow path 35, and the protrusion side auxiliary vertical fin 29 and the central vertical flow. It passes between the fins 27 and the like, is guided by the fins, and blows air from the air outlet 25 obliquely to the right. In addition, the airflow flowing toward the right side wall from the center of the flow path 35 hits the right side in the flow path 35 and hits the bulging curved surface 284 of the backward auxiliary vertical fin 28 in a vertical state, and is collected on the central vertical fin 27 side. It is done. As a result, the air flow that passes through the right side of the central vertical fin 27 and goes straight forward is blocked by the backward auxiliary vertical fin 28, and the air flow collected in the vicinity of the central vertical fin 27 is the right side of the central vertical fin 27. It flows so as to be pressed against the surface, and is then guided along the central vertical fin 27 and blown with good directivity toward the diagonally right direction.

In the registers of the first and second embodiments, the shape of the air outlets 17 and 25 is an elongated rectangle. However, the shape is not necessarily a rectangle, but an elongated irregularly shaped air outlet such as an ellipse. You can also

As long as the concave portion can accommodate the horizontal fins 8 and the lower auxiliary horizontal fins 9 or the retreat side auxiliary vertical fins 28 and the protruding side auxiliary vertical fins 29, the shape of the concave portion having a concave curved surface is arbitrary.

In addition, the air outlet 25 is inclined so that the right side is retreated to the upstream side and the left side is protruded to the downstream side. On the contrary, the left side is upstream. The air outlet can also be formed by inclining so that the right side protrudes downstream, and in this case, the backward auxiliary vertical fins 28 and the protruding auxiliary vertical fins 29 of the front movable louver 23 can be formed. The right and left positional relationship is opposite to the above.

It has an elongated air outlet that is long in the vertical and vertical directions and short in the horizontal and horizontal direction, and a front movable louver is disposed along the vertical and vertical direction inside the air outlet. In a register formed with an inclination so that the side part is retracted upstream and the other side part protrudes downstream,
   The front movable louver pivotally supports one central vertical fin at a substantially horizontal center inside the air outlet so as to be pivotable in the vertical direction, and is provided on the side wall surface on the retreat side inside the air outlet. The retraction side auxiliary vertical fin can be stored in the storage recess and pivoted in the vertical direction so that it protrudes into the storage recess provided on the side wall surface on the protrusion side inside the air outlet. It is configured to pivotally support the fins so that the fins can be stored in the vertical direction.
   The central vertical fin is pivotally supported by upper and lower support shafts so as to be pivotable in the left-right direction, and the receding side auxiliary vertical fin and the protruding side auxiliary vertical fin are formed with a bulging curved surface on one side and a flat surface on the other side. In addition, it is pivotally supported so as to protrude toward the flow path side and rotate.
   When the central vertical fin is swung to the protruding side, the backward auxiliary vertical fin rotates so that the flat surface is substantially parallel to the central vertical fin, and the protruding auxiliary vertical fin is the bulging curved surface. When the central vertical fin is swung toward the backward side, the flat surface of the auxiliary auxiliary vertical fin is substantially parallel to the central vertical fin. And the retreating side auxiliary vertical fin is rotated so that the bulging curved surface faces the upstream side and protrudes toward the flow path side.
