Thus, the rotation shaft 21 of the first linkage door 27A is rotated.

  And the wind direction of an air-conditioning wind can be swung by combining the above wind distribution patterns. For example, by alternately repeating the air distribution patterns of FIGS. 5 and 6, the conditioned air can be swung up and down in the passenger compartment. Further, by alternately repeating the air distribution patterns of FIGS. 7 and 8, the conditioned air can be swung in the left-right direction in the vehicle interior. Furthermore, by randomly selecting an air distribution pattern from FIG. 5 to FIG. 13, it is possible to swing without specifying the direction of the conditioned air.

  Moreover, a more comfortable vehicle interior space can be provided to the occupant by swinging the direction of the conditioned air.

  In the present embodiment, the partition 61 is provided in the upper vent duct 63 and the center vent air passage 65, but the above-described effects can be obtained without such a partition.

If it is connected to the right side of 75, the same effect can be produced.

  Furthermore, since each opening part and each blower outlet are connected without making the shape of each duct complicated, a more comfortable vehicle interior space can be provided to a passenger | crew, without enlarging the whole apparatus.

  Further, the shape of each door 20 is not limited to a pentagon, and as shown in FIG. 15, a so-called butterfly door 20 having a circular door surface 22 may be used.

  Further, as shown in FIG. 16, by removing both corners of the door surface 22 and making it a hexagon, the protruding portion from the main body 10 becomes small, so if the door 20 hits a component inside the air conditioning unit 51. As a result, the assembly workability of the main body 10 can be improved.

  Further, as shown in FIGS. 17A and 17B, along the rotary shaft 21, the door 20 is divided into a door surface 22 and door pieces 23 'and 23 ", and the door pieces 23' and 23" are separated. Are rotatably supported on the main body 10 by a rotating shaft 21 ′ provided along the rotating shaft 21, and the door surface 22 and the door pieces 23 ′ and 23 ″ are linked by a hinge mechanism 24, thereby Without narrowing the communication hole having a rectangular cross-sectional shape, it is possible to reduce the protruding portion from the main body 10 when the door 20 is fully open. The hinge mechanism 24 includes the door surface 22 and the door pieces 23 ′ and 23 ″. The rotation protrusion 25 ′ provided on the connection member 28, the rotation protrusion 25 ″ formed on the connection member 28, and a connecting pin 29 that connects the rotation protrusion 25 ′. The connecting pin 2 is inserted into the connecting hole provided in the ′, 25 ″. By inserting and enables the opening and closing operation with the rotation of the rotary shaft 21.

  With such a configuration, the size of the main body along the flow direction of the conditioned air can be reduced.

As another aspect of the embodiment, as shown in FIG. 18, there is one in which the lattice wall 11 of the main body 10 is formed so that the communication holes 13 are square. In the case of this aspect, the door 20 is also square. In the case of this aspect, since the gap between the communication hole 13 and the door surface 22 is small, it is possible to reduce the size of the closing portion 14 disposed on the inner wall surface of the lattice wall 11 that forms the communication hole 13. Therefore, a sufficient opening area of the communication hole 13 can be ensured.

  And the wind direction of an air-conditioning wind can be swung by combining the above wind distribution patterns.

  In addition, the conditioned air can be swung by relatively simple linkage means that a plurality of doors are rotated by putting an annular belt on a pulley provided at the end of the rotating shaft.

As in the embodiment , the vent opening 55B in which the main body 10 of the air distribution structure 1 is disposed is provided with an open / close door 58 that opens and closes the vent opening 55B on the upstream side of the main body 10 to open / close the vent opening 55B. By closing the door 58, it is possible to stop air blowing from the upper vent outlet 75, the center vent outlet 76, and the side vent outlet 77 that can swing the conditioned air.

This reference example has another aspect as shown in FIG. In this embodiment, the doors 20 for opening and closing the communication holes 13 as the air passages are installed in the respective communication holes 13 so as to be openable and closable, and the left upper vent door 20a is installed on the outlet side of the left upper vent communication hole 13a. A right upper vent door 20b is installed on the inlet side of the right upper vent communication hole 13b, and a left vent door 20c is installed on the inlet side of the left vent communication hole 13c, on the outlet side of the right vent communication hole 13d. The right vent door 20d is installed.

  Pulleys 31 are respectively provided at the shaft ends of the rotary shafts 21 penetrating the wall surface 12, and each of the two annular belts 32 is hung on the pulleys 31 so as to be positioned in parallel, so that each has two doors. Are linked. The linkage door 27 including the two doors 20 linked by the annular belt 32 and the pulley 31 is in a state where one door 20 closes the opening and the remaining door 20 opens the opening. Is retained.

  That is, the first linkage door 27A is linked so that the right vent door 20d and the left upper vent door 20a are held in the open position while the other door is held in the open position. Similarly, in the second linkage door 27B, the left vent door 20c and the right upper vent door 20b are linked so that the other door is held in the open position while the other door is held in the closed position. And it can make the connection means 30 compact by setting it as a structure like this aspect.

Further, in the first reference example , as shown in FIG. 22, there is a mode in which the linking means 30 is different. In this embodiment, instead of the link means by the annular belt 32 and the pulley 31, the gear 33 is provided at one end of each rotating shaft 21, and the shaft 35 is provided with a gear 34 meshing with the gear 33 at both ends. A driving force for rotating the door 20 is transmitted by the linkage means.

  And by setting it as the structure which meshes | engages several gears like this aspect, it can swing an air-conditioning wind with the comparatively simple linkage means of rotating several doors, and can make the linkage means 30 compact. In addition, since the rotary shaft 21 is not arranged on the diagonal line of the door, the space required when the door rotates can be reduced.

( Second reference example )
Air distribution structure of the second reference example, the air distribution structure 1 of one embodiment, the first linking door 27A, instead of the second linking door 27B is a configuration using other linking methods, the following, one embodiment Differences will be described while giving the same reference numerals to members having the same functions as those of the air distribution structure 1.

With the above-described configuration, this reference example can have the same air distribution pattern as that of the embodiment shown in FIGS. 5 to 13, and the four communication holes 13 that are opened and closed by each door. Since it is not necessary to open them on the same plane, the degree of freedom in designing the shape of the air distribution structure is increased, and a limited space in which the air distribution structure can be installed can be used effectively.

  Further, the conditioned air can be swung by a relatively simple linkage means in which a plurality of doors are connected by a universal joint and rotated.

  Furthermore, since it is no longer necessary to open the openings opened and closed by each door in the same plane, the degree of freedom in designing the shape of the air distribution structure is increased, and a limited space where the air distribution structure can be installed is effectively used. Can be used.
