PROBLEM TO BE SOLVED: To solve a problem on attachment of water droplets to a back face of a vertical wind direction plate due to increase of temperature difference between a front face and a back face of the vertical wind direction plate in a conventional air conditioner in which a wind direction of cold air supplied from a supply port is changed by changing a fixing position of the vertical wind direction plate without changing a fixing position of an auxiliary vertical wind direction plate in a cooling operation.SOLUTION: Whether a vertical wind direction plate is fixed in a first rotation range or not is determined (S5), and an auxiliary vertical wind direction plate is disposed in a second rotation range (S3), when the vertical wind direction plate is fixed in the first rotation range (S5:Yes). Further whether the vertical wind direction plate is fixed in a third rotation range or not is determined (S6), and the auxiliary vertical wind direction plate is fixed to a first water droplet avoidance position or a second water droplet avoidance position of a forth rotation range (S11, S12), when the vertical wind direction is fixed in the third rotation range (S6:Yes). |
