  The present invention relates to an air outlet adjustment register used for an air outlet for ventilation or air conditioning in an automobile or the like, and particularly suitable for a front inclined portion that is inclined gently downward from a horizontal plane in an instrument panel or the like in an automobile. The present invention relates to an air blowing adjustment register that can be mounted and used.

2. Description of the Related Art Conventionally, as shown in FIG. 9A, an air blowing adjustment register mounted on an instrument panel of an automobile is generally high in the height of the instrument panel itself, so that a bezel 51 that forms a design surface thereof is used. Can be formed relatively high. In addition, since the inclination angle α of the bezel 51 is a relatively large downward inclination angle of about 45 degrees to about 60 from the horizontal plane, the height H1 of the ventilation path 50 in the retainer 52 can be relatively large. did it. For this reason, even if the fins of the front movable louver 53 are juxtaposed in the ventilation path 50 and the fins of the rear movable louver 54 are juxtaposed in the rear part, the pressure loss of the air sent through the ventilation path 50 does not increase so much. The air could be blown without causing a noise or a decrease in wind speed during the blowing.
JP 2005-350029 A

  In recent years, instrument panels disposed in the front part of automobiles have a tendency that the surface from the top surface to the front surface is formed as a very gentle curved inclined surface close to the horizontal, and the height of the instrument panel itself is high. It also tends to be low. As shown in FIG. 9B, the air blowing adjustment register mounted on the front surface of such an instrument panel is limited to a relatively low height H2 of the bezel 61, and the inclination angle β of the bezel 61 is The angle of inclination is relatively small, about 30 degrees from the horizontal plane. For this reason, in the register used in this type of instrument panel, the height H3 of the ventilation path 60 in the retainer 62 is relatively small, and the vertical fins of the front movable louver 63 are arranged in parallel in the ventilation path 60. When the horizontal fins of the rear movable louver 64 are arranged in parallel at the rear portion, there is a problem that the pressure loss of the blown air that passes through the ventilation passage 60 increases, and noise during the blown air and a decrease in the wind speed are likely to occur. Further, as shown in FIG. 9B, since the inclination of the arrangement of the axial center positions of the plurality of horizontal fins of the rear movable louver becomes gentle, there is a problem that it is difficult to adjust the downward wind direction.

  On the other hand, as a register to be mounted on an instrument panel in which the surface from the upper surface to the front surface is formed as a very gentle front inclined portion that is almost horizontal, the wind direction conventionally provided with one louver body and a wind guide plate An adjustment device is proposed in Patent Document 1 described above.

  In this conventional wind direction adjusting device, one louver body is pivotally supported at the upper part of the inclined opening portion of the ventilation duct, and one wind guide plate is rotated in front of the lower side of the louver body. Installed and configured as possible. When air is directed upward using this wind direction adjusting device, the louver body is rotated so as to be directed upward, and the wind guide plate on the lower front is rotated downward. On the other hand, when changing the air flow from the top to the front, adjust the angle of the louver body from the above state to face the front side, and when changing the air flow to the bottom, adjust the tip angle of the louver body to narrow down. Further, the adjustment is performed by rotating the air guide plate upward.

  However, since the wind direction adjusting device adjusts the upward and downward wind direction by adjusting the rotation of a single louver body, it is difficult to finely adjust the wind direction from the intermediate direction to the upward direction or from the intermediate direction to the downward direction. It was. In addition, when the louver body is rotated and the air direction is directed upward or downward, the ventilation path is constricted by the louver body, so that the pressure loss of the air blow is large, and noise and air volume decrease are likely to occur. was there.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide an air blowing adjustment register capable of well adjusting the vertical wind direction and capable of performing air blowing with good directivity. .

  In order to achieve the above object, an air blowing adjustment register according to claim 1 of the present invention is for air blowing adjustment in which a retainer having a bezel on the front surface and an air passage in the lower rear portion of the bezel is attached. The height of the retainer in the ventilation path is formed to be larger than the height of the air outlet of the bezel by extending the bottom surface downward, and the inclined surface of the inclined air outlet portion of the retainer. A plurality of lateral fins of the rear movable louver are arranged side by side, and configured to prevent an air flow blown horizontally through a gap between the lowermost lateral fin of the rear movable louver and the bottom wall of the retainer. It is characterized by that.

A plurality of vertical fins of the front movable louver can be pivotally supported in the front movable louver housing portion so as to be pivotable to the left and right via upper and lower shaft support portions.

  According to the air blow adjustment register of claim 1 having the above-described configuration, the height of the retainer in the ventilation path is formed to be larger than the height of the air blow-out port of the bezel by extending the bottom surface downward. Since a plurality of horizontal fins of the rear movable louver are juxtaposed along the ventilation direction in the ventilation path, even if the air outlet of the bezel is formed as a gently sloping surface close to the horizontal, the horizontal fin and the horizontal fin The gap is not narrowed, and the air can be blown with good directivity from obliquely downward to upward without increasing the pressure loss during blowing and with low noise.

  Also, since the air flow blown through the gap between the bottom horizontal fin of the rear movable louver and the bottom wall of the retainer is blocked, when the horizontal fin of the rear movable louver is rotated upward, There is almost no draft passing horizontally between the bottom walls of the retainer. Therefore, the wind guided upward by the horizontal fins is not drawn to the bottom wall and adheres to the bottom wall, and it is possible to prevent a decrease in the central wind speed in the air blowing and to perform the air blowing with a spot feeling with good directivity. it can.

Since it is closed in accordance with the pivoting movement of the horizontal fin, even when the horizontal fin of the rear movable louver is rotated from the horizontal direction to diagonally upward, the space between the bottom horizontal fin and the bottom wall of the retainer remains in the horizontal direction. There is no ventilation. Therefore, the wind induced by the lateral fins is not drawn to the bottom wall and adheres to the bottom wall, and further prevents a decrease in the central wind speed in blowing, in the direction in which the lateral fins of the rear movable louver are directed, It is possible to blow with a spot feeling.

  Further, according to the air blowing adjustment register of claim 3, the front movable louver is disposed in front of the rear movable louver, and the plurality of vertical fins rotate to the left and right via the vertical pivot in the front movable louver. It is pivotally supported, and each vertical fin of the front movable louver is turned left and right, and an operation knob for tilting each horizontal fin of the rear movable louver up and down is fitted on the vertical fin of the front movable louver. The wind direction is adjusted up, down, left and right by operating one control knob. In other words, when the operation knob is rotated up and down, the vertical tilt angle of the rear movable louver is changed, and the wind direction is adjusted up and down. When the operation knob is slid in the left-right direction, the left and right angles of the front movable louver are changed, and the wind direction can be adjusted to the left and right.

  Further, according to the air blowing adjustment register of claim 4, by providing the damper, it is possible to block the air flow, and when the damper is opened, the damper plate of the damper is positioned in parallel with the lateral fin, As a result, it is possible to efficiently blow air obliquely downward.

It slides up or down, and the direction of the horizontal fin 41 is adjusted up and down.

  As shown in FIGS. 4 and 6, the damper 10 is supported on the rear portion of the ventilation path 20 in the retainer 2 so as to be rotatable about a horizontal axis. As shown in FIG. 4, the damper 10 has a sealing member 10b fitted around the damper plate 10a, and supports the midpoints on both sides of the damper plate 10a through the damper shafts 10c and 10d. Composed. The damper shafts 10c and 10d are disposed on a central horizontal plane in the ventilation path 20, and one damper shaft 10c is inserted from the outside to the inside of the side wall of the retainer 2 and is fitted to the edge of the damper plate 10a. The damper shaft 10d protrudes from the edge of the damper plate 10a and is rotatably fitted in a shaft hole provided in the side wall of the retainer 2. The link arm 10e is pivotally attached to the damper shaft 10c fitted from the outside, and the tip of the link arm 10e is connected to the connecting shaft 19a at the end of the link bar 19 as shown in FIG.

When the damper operation knob 6 is rotated to the position shown in FIG. 2, the damper 10 in the retainer 2 is positioned on the central horizontal plane O as shown in FIG. On the other hand, when the damper operation knob 6 is turned clockwise in FIG. 2, the link bar 19 is moved to the left side in FIG. 2, and the damper 10 is rotated in the clockwise direction to be in a closed state shown by an imaginary line in FIG.

  The air blow adjustment register having the above-described configuration is attached to, for example, an inclined front portion of an instrument panel that is gently inclined forward and downward from a horizontal plane in a front portion of a vehicle interior of an automobile. At this time, the bezel 1 is disposed along the front inclined portion of the instrument panel, and the basic ventilation direction of the ventilation path 20 in the retainer 2, that is, the central horizontal plane O passing through the ventilation path 20 is slightly inclined downward. Installed to face.

  When adjusting the air direction of the air flow, the air direction is adjusted by operating the operation knob 8 attached to the vertical fin 31 at the center of the front movable louver 3. When adjusting the wind direction up or down, the operation knob 8 is slid up or down on the vertical fin 31. By sliding the operation knob 8 up or down, the horizontal fins 41 of the rear movable louver 4 rotate about the horizontal fin shaft 41a via the engaging portion 8d and the link bar 41d, and the blowing direction. Is adjusted upward or downward including a substantially horizontal direction.

  For example, as shown in FIG. 6, when the horizontal fin 41 is adjusted to a flat state along the central horizontal plane O, the air flow in the ventilation path 20 is guided along the horizontal fin 41 and substantially horizontally. Although it will be in the state which ventilates, it will be in the state by which the airflow along the bottom part of the ventilation path 20 is interrupted | blocked. That is, the airflow that flows along the inclined surface 22 of the bottom wall of the ventilation path 20 is blocked at the intermediate step portion 22a, and the airflow that goes out in the horizontal direction or upward does not occur near the bottom wall. Therefore, the blast of the register as shown in FIG. 6 is guided to the lateral fin 41 and has a good directivity in the direction along the central horizontal plane O of the ventilation path 20, that is, in the direction facing substantially downward from the horizontal. It can blow with low noise and low pressure loss.

  On the other hand, when the operation knob 8 is slid upward, as shown in FIG. 7, the horizontal fin 41 of the rear movable louver 4 rotates about the horizontal fin shaft 41a via the engaging portion 8d and the link bar 41d. And adjusted so as to face obliquely upward. As shown in FIG. 7, when the horizontal fin 41 is adjusted so as to face obliquely upward, the air flow in the ventilation path 20 is guided along the horizontal fin 41 and is blown obliquely upward. The air flow along the bottom of the ventilation path 20 is also blocked. That is, the airflow that flows along the inclined surface 22 of the bottom wall of the ventilation path 20 is blocked at the position of the intermediate step portion 22a, and the airflow that passes through in the horizontal direction does not occur in the vicinity of the bottom wall.

  Therefore, as shown in FIG. 7, the air flow in the ventilating passage 20 of the register is guided to the horizontal fins 41 that face obliquely upward and blown obliquely upward, and the bottom of the bottom lateral fin 41 and the retainer 2. Since there is no ventilation through the walls in the horizontal direction, the wind guided by the lowermost horizontal fin 41 is not drawn downward and adheres to the bottom wall, preventing a decrease in the central wind speed in blowing. Then, it is possible to blow with a spot feeling in the direction in which the lateral fins 41 of the rear movable louver 4 are directed.

  Further, when the air direction is adjusted to the upper side, an air flow having a sufficient flow rate flows into the ventilation path 20 of the retainer 2 from the opening of the entire height H4 on the upstream side, and is narrowed in the gap between the horizontal fins 41. Instead, the air is efficiently blown obliquely upward. For this reason, the pressure loss at the time of ventilation is small, it is low noise, and it can blow with favorable directivity from the slanting lower side which faced the horizontal fin 41 to the upper part.

  Furthermore, the air blowing adjustment register is different from the conventional register in which the surface from the upper surface of the bezel to the front surface is formed as a gentle inclined surface that is nearly horizontal, and the front movable louver 3 and the rear movable louver 4 are provided with the air outlet. Therefore, the opening (indentation) when the lateral fin 41 of the rear movable louver 4 is opened is not conspicuous in appearance and does not impair good design.

  On the other hand, when adjusting the wind direction to the left or right, when the operation knob 8 is turned left or right, the vertical fins 31 of the front movable louver 3 together with the operation knob 8 are connected to the vertical fin upper shaft 31a and the vertical fin lower shaft. Rotate around 31b and change its direction to left or right.

  Thereby, the direction of each vertical fin 31 of the front movable louver 3 changes to the left and right, and the wind direction can be adjusted to an arbitrary left and right direction by a simple turning operation of the operation knob 8. In particular, even when the wind direction is directed downward by adjusting the rear movable louver 4, the air flow blown from the inclined outlet 21 passes through the lower part of the front movable louver 3 extending downward, Air can be blown with good directivity in the left-right direction adjusted by the vertical fins 31.

  On the other hand, when shutting off the air flow, the damper operating knob 6 is operated to rotate the damper 10 about the damper shafts 10c and 10d, and the ventilation path 20 is closed. At the time of blowing, the damper 10 can be rotated to a substantially horizontal state in the ventilation path 20, and the ventilation path 20 can be opened to perform low pressure loss blowing with low ventilation resistance.

  FIG. 8 shows the relationship between the lateral fin and the bottom wall of the retainer in another embodiment. In the above embodiment, the inclined surface 22 is provided on the bottom wall of the retainer 2, the intermediate step portion 22 a is provided on the upper portion (front portion) of the inclined surface 22, and the lowermost horizontal fin 41 is directly above the intermediate step portion 22 a. 8 (a) to 8 (d), the airflow flowing between the bottom horizontal fin and the bottom wall is blocked or bent, so that the horizontal fin can be turned upward. Directivity can be improved.

  That is, as shown in FIG. 8A, when the lowermost horizontal fin 411 is arranged on the flat portion at the upper part of the inclined surface 222 of the retainer bottom wall, and the horizontal fin 411 is rotated obliquely upward, it is flat. The gap between the horizontal fin 411 and the horizontal fin 411 is narrowed to block the airflow flowing between the horizontal fin 411 and the bottom wall. Thereby, the airflow which flows between the lowermost horizontal fin 411 and a bottom wall is interrupted | blocked, and the malfunction that the upward airflow induced | guided | derived by the horizontal fin 411 adheres to a bottom wall is prevented. For this reason, the directivity at the time of upward ventilation can be improved, the fall of the central wind speed of ventilation can be prevented, and favorable ventilation with a spot feeling can be implement | achieved.

  Further, as shown in FIG. 8B, an intermediate step portion 223a is provided on the upper portion of the inclined surface 223 of the retainer bottom wall, and the horizontal fin 412 is disposed on the upper portion of the inclined surface 223b of the intermediate step portion 223a. And when the horizontal fin 412 is made diagonally upward, it arrange | positions so that the lower surface of the horizontal fin 412 may substantially contact | abut to the inclined surface 223b. Thereby, when the horizontal fin 412 is rotated obliquely upward, the gap between the inclined surface 223b of the intermediate step portion 223a and the horizontal fin 412 is narrowed to flow between the horizontal fin 412 and the bottom wall. Air flow can be blocked.

  Further, as shown in FIG. 8C, an intermediate step portion 224a is provided on the upper portion of the inclined surface 224 of the retainer bottom wall, a horizontal fin 413 is disposed immediately above the intermediate step portion 224a, and the horizontal fin 413 is attached. When it is obliquely upward, the lower fins 413 are arranged so that the lower ends of the horizontal fins 413 substantially come into contact with the intermediate step 224a. As a result, when the horizontal fin 413 is rotated obliquely upward, the gap between the intermediate step portion 224a and the end of the horizontal fin 413 is narrowed, and the airflow flowing between the horizontal fin 413 and the bottom wall is reduced. Can be blocked.

  Further, as shown in FIG. 8 (d), a first intermediate step 225a and a second intermediate step 225b are provided on the upper portion of the inclined surface 223 of the retainer bottom wall, and the first intermediate step 225a and 225b are provided. A horizontal fin 414 is disposed directly above. When the horizontal fin 414 is leveled, the front portion of the horizontal fin 414 substantially contacts the second intermediate step portion 225b, and when the horizontal fin 414 is inclined upward, the rear portion of the horizontal fin 412 is the first intermediate step portion. It arrange | positions so that it may contact | abut substantially on the inclined surface of 225a.

  Thereby, when the horizontal fin 414 is rotated horizontally or obliquely upward, the gap between the first intermediate step 225a or the second intermediate step 225b and the horizontal fin 414 is narrowed, and the horizontal fin 414 The airflow flowing between the bottom wall can be blocked. Therefore, it is possible to prevent the upward air flow induced by the lateral fins 414 from adhering to the bottom wall at the time of upward, and to improve the directivity at the time of upward air blowing, to prevent the reduction of the central wind speed of the air blowing, Good ventilation can be achieved.
