Abstract

An aspect of the present invention relates to an air conditioner which is provided with a structural body, a wind direction plate, and auxiliary housings. The structural body forms an air outlet that extends in a horizontal direction and blows out a cool or warm airflow which is generated by a heat exchanger on a downward-facing surface which is continuous downward from a front surface, and includes one pair of wall bodies which are fixed to be immovable with respect to the air outlet on both sides of the first air outlet. The wind direction plate is disposed in the air outlet and is supported by the structural body to be freely rotatable around a horizontal shaft line. The auxiliary housings are attached to an outer wall surface of the wall body to be freely rotatable around a horizontal shaft on both sides of the air outlet, and form an auxiliary air outlet which blows out taken-in indoor air. Furthermore, a distance L1 from an imaginary shaft line to the auxiliary air outlet is set to be longer than a distance L3 from the imaginary shaft line to the air outlet of the structural body.

First claim

The invention claimed is:

1. An air conditioner, comprising: a structural body having a front surface and a downward-facing surface which is continuous downward from the front surface, the structural body forming an air outlet in the downward-facing surface, wherein the air outlet extends in a horizontal direction and blows out a cool or warm airflow which is generated by a heat exchanger, the structural body including one pair of wall bodies which are fixed to both sides of the air outlet; a wind direction plate which is disposed in the air outlet and is supported by the structural body for relative rotation around a first horizontal axis of pivot; and auxiliary housings which are attached to an outer wall surface of the wall body for relative rotation around a second horizontal axis of pivot on both sides of the air outlet, each of the auxiliary housings forming an auxiliary air outlet which blows out a room temperature air separate from the cool or warm airflow, wherein a distance LI from an imaginary axis including the second horizontal axis of pivot to the auxiliary air outlet is set to be longer than a distance L3 from the imaginary axis to the air outlet of the structural body, a first driving source which drives a first blower fan that is installed in the structural body and generates the cool or warm airflow; and a second driving source which drives a second blower fan that is installed in the auxiliary housing and generates the airflow of the room temperature air, wherein the second blower fan is a centrifugal fan which rotates around a rotation axis which coincides with the imaginary axis, and generates an airflow which is blown out of the auxiliary air outlet.

2. The air conditioner according to claim 1 , further comprising:
a blowing path which is defined in the auxiliary housing, and extends from a space below the centrifugal fan to the auxiliary air outlet.

3. The air conditioner according to claim 1 ,
wherein a distance L2 from the imaginary axis to the front surface of the structural body is set to be longer than the distance L3, and L1>L2.

4. The air conditioner according to claim 2 ,
wherein a distance L2 from the imaginary axis to the front surface of the structural body is set to be longer than the distance L3, and L1>L2.
