Description

  The present invention relates to an air conditioner including a blowout port having a wind direction plate, and more particularly to an air conditioner including a wind speed adjusting plate that defines an opening area of the blowout port.

  In the air conditioner, the wind speed of the blown air, that is, the reach distance of the blown air is determined by the opening area of the blower outlet for a predetermined blown air amount. Therefore, in order to make the blown air reach the target position with respect to a predetermined blown air amount, the opening area of the blower outlet is determined so as to obtain a predetermined blown air velocity, and the housing is designed.

  By the way, in the ceiling-embedded air conditioner having four air outlets, the air passage width provided with a baffle plate that adjusts the air flow rate and the air speed by changing the air passage width (opening area) of the air outlet. There has been proposed an adjustment mechanism that can vary the amount and speed of air blown from each outlet according to the installation location (see, for example, Patent Document 1).

  Moreover, in the said patent document 1, when the wind direction plate which guides a blowing flow is provided in the blower outlet located downstream from the baffle plate, a small hole is provided in the baffle plate, and thereby the air flow along the wind direction plate is generated. In order to obtain a large amount, it has also been proposed that the wind direction can be reliably adjusted by the wind direction plate.
