  Further, from the state shown in FIG. 5A, when the uneven portion 51 of the dial 15 is operated to rotate the dial 15 to the left, the interlocking portion 56 is interlocked in the same manner as described above, and each cam 16 (first Or the third cams 16a, 16b, 16c) are interlocked and rotated counterclockwise as shown in FIGS. Specifically, in the first cam 16a, the first slide shaft 42a of the first flap 14a slides along the second section 72a2 of the first cam groove 72a, and the front side of the first flap 14a is the first side. The first cam 16a moves away from the central axis side and approaches the outer edge side of the first cam 16a, that is, rotates upward to open the first air outlet 34a (FIG. 5B). FIG. 6 (c)). In the second cam 16b, the second slide shaft 42b of the second flap 14b slides along the second section 72b2 of the second cam groove 72b, and the front side of the second flap 14b is the second cam 16b. The second air outlet 34b is closed by rotating downward so as to approach the central axis side, that is, in contact with the inclined surface 43 (FIGS. 5B and 7C). Further, in the third cam 16c, the third slide shaft 42c of the third flap 14c slides along the second section 72c2 of the third cam groove 72c, and the third outlet 34c is closed. Maintain (FIG. 5 (b), FIG. 8 (c)). As a result, the second and third air outlets 34b and 34c are closed and only the first air outlet 34a is opened, and slightly closer to one side (left side) from the first air outlet 34a located on this one side. As the wind spreads forward, the wind blows out to the side of the occupant, that is, the avoidance wind state.

  5B, when the uneven portion 51 of the dial 15 is operated to rotate the dial 15 to the left, the interlocking portion 56 is interlocked in the same manner as described above, and each cam 16 (first Or the third cams 16a, 16b, 16c) are interlocked and rotated counterclockwise as shown in FIGS. Specifically, in the first cam 16a, the first slide shaft 42a of the first flap 14a slides along the third section 72a3 of the first cam groove 72a, and the front side of the first flap 14a is the first side. It rotates so that it may approach the center axis | shaft side of the 1 cam 16a, ie, below, and the 1st blower outlet 34a is obstruct | occluded (FIG.5 (c), FIG.6 (d)). At this time, the first slide shaft 42a slides from the second section 72a2 to the third section 72a3 while making contact with the curved portion 75, so that the first slide shaft 42a is caught in the first cam groove 72a or rattling occurs. Without moving, it moves to the movable section 77 after passing through the short non-movable section 76, so that it slides smoothly and accurately. In the second cam 16b, the second slide shaft 42b of the second flap 14b slides along the third section 72b3 of the second cam groove 72b, and the second outlet 34b is closed. Maintain (FIG. 5 (c), FIG. 7 (d)). Further, in the third cam 16c, the third slide shaft 42c of the third flap 14c slides along the second section 72c2 of the third cam groove 72c, and the third outlet 34c is closed. Maintain (FIG. 5 (c), FIG. 8 (d)). As a result, the first to third outlets 34a, 34b, and 34c are all closed (closed state), and the state where the wind does not blow out, that is, the shut state is established.

  Summarizing the operation of the series of flaps 14 in the present embodiment, from the open state to the closed state, the first flap 14a continuously operates as open, closed, open, closed, and the second flap 14b is , Open, open, closed and closed, and the third flap 14c operates continuously as open, closed, closed and closed. Accordingly, the first to third flaps 14a, 14b, and 14c perform different opening / closing operations.

  In the above description, the state in which the dial 15 is operated to the position where each air outlet 34 is completely opened or completely closed by each flap 14 is shown, but each flap 14 rotates continuously. Therefore, when the operation of the dial 15 is stopped at an intermediate position between the open state and the closed state of the air outlet 34, the air outlet 34 can be opened about half (closed about half), so-called half open state. Further, when the dial 15 is rotated in the opposite direction, the operations are respectively reversed.

  As described above, according to the present embodiment, the number of the cams 16 is interlocked by the number of the cams 16 that is smaller than the number of the plurality of flaps 14, in this embodiment, one dial 15. Therefore, compared with the case where a large number of dials are provided, for example, the opening areas of the plurality of air outlets 34 can be individually varied with a simpler structure, and effective wind direction control is possible.

  In particular, in the thin air outlet 10 that is considerably long in the longitudinal direction and short in the lateral direction, it is not easy to control the wind direction in the lateral direction and in the vertical direction in the present embodiment. Although the wind direction is controlled using these, in order to make these flaps 14 operate differently from each other, the same number of operation means as the normal flaps 14 are required, and the operability and the design are deteriorated. In this respect, in the present embodiment, since the plurality of flaps 14 can be easily operated differently by the single dial 15 as described above, the operability and the design are excellent, and the configuration is simple and inexpensive. Can be provided.

  In addition, since each cam 16 having cam grooves 72 having different shapes is rotated in conjunction with each other by operation of the dial 15, each flap 14 guided by the slide shaft 42 by the cam groove 72 is operated. With such a configuration, the flaps 14 can be easily operated differently from each other.

  In addition, since the operation of the flap 14 can be easily controlled by setting the shape of the cam groove 72, the flap 14 can be easily operated as desired.

  Further, by changing the opening area of the air outlet 34 by rotating the flap 14, it is possible to easily realize a configuration that changes the opening area of the air outlet 34. For example, in the open state, the air passage 32 passes through the ventilation path 32 by overlapping the case body 13. It is difficult to obstruct the flow of air to be seen, and it is difficult to see from the outside, so that the appearance can be improved.

  Furthermore, since the flap 14 is operated by the dial 15 rotatably arranged on the case body 13, the operation is easy, and the plurality of flaps 14 can be easily operated with a simple configuration.

  In addition, in the cam groove 72, the first cam groove 72a is provided with a curved portion 75 that is gently curved at a position where the second section 72a2 and the third section 72a3 where the operation direction of the flap 14 is switched are continuous. By providing the non-movable section 76 in which the flap 14 (first flap 14a) does not operate, the flap 14 (first flap 14a) can be operated smoothly and accurately.

  Since the flap 14 pivotally supports the rotation shaft 41 on the upper side of the air outlet 34, the flap 14 is overlaid on the upper wall portion 25 in a state where the air outlet 34 is opened, and it is difficult to see from the outside. It can be improved.

  Further, since the gear portion 52 of the dial 15 is disposed on the rear side of the dial 15 and the cam gear portion 73 of the cam 16 is disposed on the rear side of the cam 16, the gear portion 52 and the cam gear portion 73 are visually observed from the front. It is hard to be done and can improve design nature.

It is supposed to be.

  That is, the first to third flaps 14a, 14b, 14c are adjacent to the adjacent flap 14 (in this embodiment, the first and second flaps 14a, 14b and the second and third flaps 14b, 14c). Are not opposite to each other, and the non-adjacent flaps 14 (the first and third flaps 14a and 14c in this embodiment) do not operate simultaneously, in other words, the first to third flaps 14a, 14b and 14c Not all work at the same time.

  The operation direction of the dial 15 is controlled by controlling the operation of the flap 14 (first to third flaps 14a, 14b, 14c) so that the wind direction moves in accordance with the rotation direction of the dial 15 by the cam groove 72. And the blowing direction of the wind coincide with each other and the usability is improved.

  Further, the wind direction can be finely adjusted in the horizontal direction by interlocking the adjacent flaps 14 so that the opening and closing of the adjacent flaps 14 are opposite to each other.

  These functions can be easily realized only by controlling the operations of the plurality of flaps 14.

  In the second embodiment, the first to third flaps 14a, 14b, and 14c are basically set to be in a fully open state, a half open state, and a closed state. The cam groove 72 can also be set finely so as to provide the open state.

  Further, the flaps 14 that are not adjacent to each other are not operated at the same time. For example, when four or more outlets 34 and flaps 14 are set, the cam groove 72 is set so that three or more flaps 14 are operated simultaneously. You can also.

  Further, in each of the above embodiments, the cam grooves 72 are set so that the flaps 14 all operate differently. However, if at least two flaps 14 operate differently, the remaining other flaps 14 The same operation as the flaps 14 other than the flap 14 may be performed. For example, a plurality of first to third flaps 14a, 14b, and 14c in each of the above embodiments are set, and a plurality of first flaps 14a, a plurality of second flaps 14b, and a plurality of third flaps are set. The flaps 14c may be set to perform the same operation.

  Each flap 14 pivotally supports the rotation shaft 41 on the case body 13 at a position above the air outlet 34, but the flap 14 may also pivotally support the rotation shaft 41 on the case body 13 at a position below the air outlet 34. Good.

  In addition to the configuration in which all the air outlets 34 are opened and closed by the flaps 14 respectively, a configuration in which one or more air outlets 34 that are always open without providing the flaps 14 may be provided.

  In addition to being manually operated by the user, the dial 15 can be automatically operated, for example, by being connected to a motor or the like.

  The blower outlet 34 and the flap 14 should just be multiply arranged, and are not limited to three.

  Although the case body 13 has the left-right direction as the longitudinal direction, the longitudinal direction can be arbitrarily set according to the layout on the vehicle.

  The case body 13 is formed in a longitudinal shape, but may not necessarily be in a longitudinal shape. That is, the air outlet 34 does not need to be long, and may be a square shape, for example.

  The air outlet device 10 can be used not only as a part of a vehicle air conditioner but also as a part of an arbitrary air conditioner.

  The present invention can be applied, for example, as an air outlet of an air conditioner provided in an automobile instrument panel or the like.
