  First, a description will be given of when the air conditioner is stopped. As shown in FIG. 1, the 1st up-and-down wind direction change blade | wing 8a closes the downward direction of the blower outlet 2c. The first left / right wind direction changing blade 9a and the second left / right wind direction changing blade 9b are in a contracted state in conjunction with the first up / down wind direction changing blade 8a, and are in the first recess 12a and the second recess 12b. Stored.

Next, the air conditioner during air conditioning operation will be described. When the air conditioner starts the air conditioning operation, the first up / down air direction changing blade 8a and the second up / down air direction changing blade 8b perform the opening operation, and the air outlet 2
c is released. As the first up / down air direction changing blade 8a rotates downward, the left / right air direction changing blade 9 extends with the upper end fixed to the support plate 12 and the lower end fixed to the first up / down air direction changing blade 8a.

  When the air conditioning operation is stopped, the first up / down air direction changing blade 8a and the second up / down air direction changing blade 8b in the state where the air outlet 2c is covered with the first up / down air direction changing blade 8a and the second up / down air direction changing blade 8b. When the lower surface (front surface) is defined as a “design surface”, at least one of the first left and right wind direction changing blades 9a and the second left and right wind direction changing blades 9b is in a state where the first up and down air direction changing blades 8a are opened during the air conditioning operation. Some are located below the design surface. That is, at the time of the air-conditioning operation, at least a part of the first left / right air direction changing blade 9a and the second left / right air direction changing blade 9b is located downstream from the air outlet 2c.

  The first up / down air direction changing blade 8a is provided at the outlet 2c downstream of the rear guider 7, and allows the air blown from the outlet 2c to smoothly reach a desired region. In particular, the first up / down wind direction changing blade 8a is located at a position where the rear guider 7 is extended, and has a function as a diffuser that exhibits a high rectifying effect on the air from the air outlet 2c.

  For example, as shown in FIG. 2, in a state where the upper surface of the first up / down air direction changing blade 8 a and the flat portion of the rear guider 7 are located on substantially the same plane, the first up / down air direction changing blade 8 a is Act as part of

  The first left / right wind direction changing blade 9a and the second left / right wind direction changing blade 9b can smoothly control the wind direction in the desired left / right direction of the flow rectified by the rear guider 7.

  As described above, the air conditioner of the present embodiment can reduce the size of the indoor unit 1 because the left and right wind direction changing blades 9 can be retracted and stored in the main body 2 when the air conditioning operation is stopped. Further, during the air-conditioning operation, the left and right wind direction changing blades 9 can be extended and at least a part of the left and right wind direction changing blades 9 can be moved downstream (externally). Since it reaches the wind direction changing blade 9, the ventilation resistance is reduced and the air blowing performance is improved.

  Further, during the air conditioning operation, the wind direction performance is improved because the left and right wind direction changing blades 9 are arranged in a region sandwiched between the stabilizer 11 and the first up and down wind direction changing blades 8a.

  A plurality of support plates 12 are arranged in the longitudinal direction of the air outlet 2c. For this reason, it is possible to prevent the finger from reaching the fan 6 even when the user inserts a finger or the like through the air outlet 2c during the air-conditioning operation.

In the present embodiment, the up / down wind direction changing blade 8 includes the first up / down wind direction changing blade 8a and the second up / down wind direction changing blade 8a.
However, it may be either the first up / down air direction changing blade 8a or the second up / down air direction changing blade 8b.

  The left and right wind direction changing blades 9 have been described on the assumption that either the upper end or the lower end rotates. However, a central axis of the upper and lower ends of the left and right wind direction changing blades 9 is provided with a rotation shaft that protrudes from the upper end or the lower end. Both the lower end and the lower end may be rotated.

  At the time of air conditioning operation, as shown in FIG. 4, the left and right wind direction changing blades 19 are opened in conjunction with the first up and down wind direction changing blades 8 a while the up and down wind direction changing blades 8 are open. That is, at the time of air-conditioning operation, at least a part of the left / right wind direction changing blade 19 is located downstream from the air outlet 2c. Or at the time of an air-conditioning driving | operation, at least one part of the left-right wind direction change blade | wing 19 is arrange | positioned outside the main body 2. FIG.

  As described above, the air conditioner of the present embodiment can fold the left / right wind direction changing blade 19 and store it in the main body 2 when the air-conditioning operation is stopped, so that the indoor unit 1 can be made compact. Further, at the time of air-conditioning operation, at least a part of the left and right wind direction changing blades 19 can be moved downstream (outside) without overlapping the left and right wind direction changing blades 9, so that the distance from the fan 6 becomes longer and the wind speed is reduced. Then, since the left and right wind direction changing blades 19 are reached, the ventilation resistance is reduced and the blowing performance is improved.

  Further, during the air-conditioning operation, the wind direction performance is improved because the left and right wind direction changing blades 9 are arranged in a region sandwiched between the stabilizer 11 and the first up and down wind direction changing blades 8a.

The air conditioner of this invention can improve the wind direction change performance of the left-right direction, and can exhibit the high rectification effect with respect to the air from a blower outlet. Further, by positioning the right and left wind direction changing blades at a location where the wind speed is low, ventilation resistance can be reduced and air blowing performance can be improved. Moreover, even if a hand is mistakenly inserted from the air outlet, the right and left wind direction changing blades prevent the insertion of the hand, and the distance to the fan is secured to prevent the fingertip from reaching the fan, thereby ensuring safety. in this way,
It is useful as an air conditioner used for business use and general households.
