  • a wind direction adjusting apparatus configured to adjust the blowing direction of cooled or heated air is provided at a blowout port of an indoor unit of an air conditioner.
  • the wind direction adjusting apparatus including a wind direction plate (the same as vertical flap) having a bendable soft portion, and being configured to adjust the blowing direction by bending the soft portion, which was disclosed long ago (for example, see Patent Literature 1).

  • the rotation shafts are arranged in series to blowout air direction along the air duct.
  • the downstream side vane includes a rotation axis and a coupling action axis.
  • the rotation axis is coupled with a coupling rod to interlock with the adjoining guide vane.
  • the coupling action axis is rotatably coupled with an interlocking arm.
  • the interlocking arm is fixed and connected to the upstream side vane. Rotation motion of the guide vane motor is transferred to the coupling rod. When the coupling rod moves, the downstream side vane rotates about the rotation shaft. This movement is transmitted to the upstream side vane by the interlocking arm and the upstream side vane rotates about the rotation shaft.
  • the wind direction plate in the first row and the wind direction plate in the second row disclosed in Patent Literature 2 are both integrally molded, and hence the above-described problem is solved.
  • the wind direction plate in the first row and the wind direction plate in the second row are provided in a staggered arrangement, that is, are arranged at a predetermined interval in a plane vertical to the blowing direction. Therefore, there arises a problem that the air flow collides against both end surfaces of the wind direction plate in the first row on the windward side and end surfaces of the wind direction plate in the second row on the windward side, and hence the draft resistance is increased, whereby the energy loss is generated.

  • the first wind direction plate and the second wind direction plate both are coupled so as to be rotatable about the coupled center of rotation, the first vane and the second vane behave as if they were a single plate.
  • the air since the first wind direction plate and the second wind direction plate overlap with each other like a single flat plate when the air is blown out in the front direction, the air only collides against an end surface of one of the first wind direction plate or the second wind direction plate and does not collide against end surfaces of both of the first wind direction plate and the second wind direction plate as in the case of the staggered arrangement in the related art. Therefore, the air flow is smoothened, the increase in draft resistance is restrained, and the energy saving effect is obtained.
  • the second wind direction plate is rotated with the coupled center of rotation as a fulcrum and the second center of rotation as a point of lever where a force is applied, it may be regarded such that it is rotated with the coupled center of rotation as a point of lever where a force is applied and the second center of rotation as a fulcrum.
