- the drive mechanism 70 is provided in place of the head 76 of the bolt 72 in addition to the components of the drive mechanism 70 described in the third embodiment, and is integrally rotatable.
- the motor 83 is driven via the control unit 85 by a remote controller (not shown) or the like, the rotation is transmitted to the bolt 72 via the worm gear 82 and the worm wheel 81.
- the baffle plate 41 is displaced similarly to the third embodiment.
- the air passage width adjusting mechanism 40 moves the short side direction of the outlet 11. Wind path width Since W1 is made narrower, it is not necessary to narrow the air passage width W2 in the longitudinal direction of the outlet 1 1, and the air passage width W2 can be maintained as in the case where the blown air volume is not suppressed. Width along the hand direction) can be maintained wide.
- the width W2 of the air outlet 11 in the longitudinal direction is reduced when the amount of the blown air is reduced
- the width of the blown air becomes narrower.
- the air conditioning range becomes narrow.
- the blow-off flow is widely maintained, and a wide range of the room can be air-conditioned, so that the stagnant air does not stay in a part of the room and the comfort is improved. It can be done.
- the blowout flow can be distributed evenly throughout the room, unnecessary cooling and heating operations can be avoided, and as a result, the cooling and heating efficiency can be improved. This means that if the outlet flow does not reach the room evenly, the entire room will be excessively cooled and heated more than necessary in order to obtain comfort in some parts of the room. This is because the cooling / heating efficiency may be reduced.
- the baffle plate 41 since the baffle plate 41 is rotated, the air volume can be adjusted with a simple structure without reducing the lateral width of the blowout flow. Moreover, the baffle plate 41 that is rotated around the axis C of the first shaft 53 and the second shaft 56 extending in the longitudinal direction is disposed in the outlet 11 in comparison with the baffle plate that slides and displaces. The desired air path width can be adjusted in a small space.
- baffle plate 41 can be folded by relatively rotating the first plate 44 and the second plate 45 connected to each other, a desired adjustment of the air path width can be realized in a small space.
- the displacement mechanism 42 fixes the fixed portions provided on the first plate 44 and the second plate 45 and moves the driving portion in the short direction.
- the connecting portion 52 is driven to move along with the driving along the guide groove 60 along. Accordingly, the air path width can be adjusted by the baffle plate 41 by interlocking the two plates 44 and 45 by the easy operation of moving the drive unit along the guide groove 60. Further, since the direction in which the third shaft 57 serving as the driving unit is driven coincides with the direction in which the air passage width is adjusted, the operation is easy to understand.
- the baffle plate 41 is disposed immediately upstream of the wind direction plate 13.
- the baffle plate 41 having the small holes 65 can accurately regulate the amount of blown air when the air passage width is minimized (closed position). This is because, when the width of the air path is narrowed most, and when the width of the air path is wide, if the amount of change in the air path width is adjusted to adjust the amount of air blown out, the amount of adjustment to the amount of air blown out when narrowed Is larger than when it is wide. This is because the change in the ratio can be suppressed by the small holes 65.
- the first to third shafts 53, 56, 57 are guided along the corresponding grooves 66, 67, 68. Therefore, no matter which axis is driven, the other axis is driven to displace the baffle plate 41 smoothly, and the air path width can be similarly adjusted. As described above, it is only necessary to provide a drive mechanism for driving any one of the shafts along the groove that guides this shaft. Can be higher.
- the screw type driving mechanism 71 includes a bolt 72 which is driven to rotate with its axial movement restricted, and a non-rotatable nut 73 which engages with the bolt 72 and moves integrally with the driven shaft. Is provided, so that the structure of the drive mechanism can be simplified and the size can be reduced.
- the screw drive mechanism 71 is unlikely to be displaced by a reverse input from the driven side, it is possible to prevent the baffle plate 41 from being displaced by wind pressure, and as a result, the above-described holding mechanism 43 can also be used. it can.
- the drive mechanism 70 since the drive mechanism 70 is driven by power, the adjustment of the air passage width can be easily performed by remote control or the like.
- the air path width adjusting mechanism 40 of the present invention includes a decorative panel 4 provided with a plurality of air outlets 11 and disposed on a ceiling, and a decorative panel 4 disposed above the decorative panel 4.
