1. An air-conditioning indoor unit operable in a Coanda effect use mode in which a flow of blown air blown out from a blow-out port is diverted in a predetermined direction via the Coanda effect, which is a phenomenon whereby a gas attempts to flow in a direction along a surface next to the flow and in a different direction than the flow, the air-conditioning indoor unit comprising:
a scroll arranged and configured to lead conditioned air to the blow-out port, a tangent to a final end of the scroll being oriented downward; a Coanda vane provided in proximity to the blow-out port, the Coanda vane being arranged and configured to alter an airflow direction of the blown air via the Coanda effect and to turn the blown air into a Coanda airflow along a bottom surface thereof in the Coanda effect use mode; and a controller configured to control an orientation of the Coanda vane, a convex shaped curved surface being formed in the bottom surface of the Coanda vane, the curved surface having a radius of 50 to 300 mm, the controller being configured
to adjust the orientation of the Coanda vane away from a casing front surface as the Coanda vane separates from the blow-out port in the Coanda effect use mode, andto adjust the orientation of the Coanda vane so that a distal end of the Coanda vane is oriented upward, and the distal end of the Coanda vane being positioned farther outward and upward than the blow-out port with an orientation more forward and upward than horizontal in the Coanda effect use mode, with a position of a rear end of the Coanda vane being at a lower height than when operation has stopped. |
