In an air outlet structure 10 of an air conditioner, conditioned air is generated from a plurality of flow paths 30C, 30L, 30R in a case 12 by moving shutter members 39, 40 in response to an operation of a left / right adjustment knob 33. It is the structure which selects the flow path which flows. Therefore, it is not necessary to provide a plurality of fins for changing the right and left blowing direction in the flow path in the case 12. As a result, the effective cross-sectional area of the flow path in the case 12 can be secured, and the air volume and speed of the conditioned air can be sufficiently secured. In addition, the flow paths 30C, 30L, and 30R in the case 12 are assigned in advance in a predetermined blowing direction, and it is possible to obtain conditioned air with excellent directivity. Moreover, since the effective cross-sectional area of the flow path in the case 12 can be ensured as described above, the air outlet 74 into the vehicle interior can be made thinner in the vehicle vertical direction or the vehicle left-right direction than before.

  In the air outlet structure 10 of the air conditioner according to the present embodiment, when the conditioned air is blown out from the air outlet of the air conditioner (not shown), the air conditioned air is blown out from the air outlet 74 through the case 12. At this time, if the left / right adjustment knob 33 is rotated to one side (R1 side), the gears 34, 35, 36 and the shafts 37, 38 are rotated in a predetermined direction, whereby the shutter members 39, 40 are moved to the case 12. Move to the center side (H1 side). As shown in FIG. 4, when the shutter members 39, 40 move to the center position of the case 12, the shutter members 39, 40 overlap in the vehicle front-rear direction and close the flow path 30 </ b> C among the plurality of flow paths. In this state, the conditioned air is selected to flow through the flow paths 30R and 30L among the plurality of flow paths. Accordingly, the conditioned air X is blown out from the outlet 74 in the right direction (R direction) and the left direction (L direction).

  At this time, the flow direction of the flow path 30R for blowing the conditioned air in the right direction (R direction) is controlled by the wall portion 26 and the side wall portion 20B. ) Air-conditioning wind with high directivity is blown out. Similarly, the flow direction of the flow path 30L for blowing the conditioned air in the left direction (L direction) is controlled by the wall portion 28 and the side wall portion 20B. Air-conditioning wind X with high directivity is blown out.

  Further, at this time, since the fins for changing the right and left blowing directions are not provided in the flow paths 30R and 30L, an effective sectional area in the case 12 is secured, and the airflow and the air velocity from the air outlet 74 are sufficiently air-conditioned. Wind X is obtained.

  On the other hand, when the left / right adjustment knob 33 is rotated to the other side (R2 side), the gears 34, 35, 36 and the shafts 37, 38 are rotated in a predetermined direction.

Is formed, and the actual opening area of the air outlet 202A is reduced. Therefore, when the actual opening area of the air outlet 202A decreases, the air volume and the air speed of the conditioned air become insufficient. Further, in order to ensure the air volume and speed of the conditioned air, it is necessary to enlarge the air outlet 202A. However, when the air outlet 202A is enlarged, the air outlet 202A has a structure that is thin in the vehicle vertical direction or the horizontal direction. Difficult to do.

  On the other hand, according to the air outlet structure 10 of the air conditioner according to the present embodiment, as described above, the shutter members 39 and 40 provided in the case 12 move in accordance with the operation of the left and right adjustment knob 33, thereby making the case. 12 is selected from the flow paths 30C, 30L, and 30R in the flow path 12 in the case 12, and therefore the right and left blowing direction changing fins (fins of the comparative example) are added to the flow paths 30C, 30L, and 30R in the case 12. It is not necessary to provide a plurality of the equivalents to 204. Therefore, the effective cross-sectional areas of the flow paths 30C, 30L, and 30R in the case 12 can be secured, and the air volume and the wind speed of the conditioned air can be sufficiently secured.

  Further, the flow paths 30C, 30L, 30R in the case 12 are assigned in advance in a predetermined blowing direction, and among the plurality of flow paths 30C, 30L, 30R, the flow paths through which the conditioned air is sent are shutter members 39, 40. It is possible to control the blowing direction of the conditioned air from the air outlet 74 in the vehicle interior and to obtain conditioned air with excellent directivity. In addition, since the effective cross-sectional areas of the flow paths 30C, 30L, 30R in the case 12 can be ensured as described above, the air outlet 74 into the vehicle interior has a structure that is thinner in the vehicle up-down direction or the vehicle left-right direction than the structure of the comparative example. Is possible. Thereby, the design freedom of the instrument panel 70 can be improved.

  Further, in the air outlet structure 10 of the air conditioner according to the present embodiment, as described above, it is not necessary to provide a plurality of fins for changing the left and right blowing directions in the flow paths 30C, 30L, 30R in the case 12, so that Generation of noise due to interference of the conditioned air with the fins in the case 12 can be prevented.

  Next, the modification of the blower outlet structure 10 of the air conditioner which concerns on 1st embodiment of this invention is demonstrated.
