Abstract

An air-conditioning indoor unit is operable in a Coanda effect use mode in which blown air from a blow-out port is diverted in a predetermined direction. The indoor unit includes a scroll leading conditioned air to the blow-out port, a Coanda vane in proximity to the blow-out port, and a controller controlling orientation of the Coanda vane. The Coanda vane alters an airflow direction of the blown air via the Coanda effect and turns the blown air into a Coanda airflow along a bottom surface of the Coanda vane. A convex shaped curved surface formed in the bottom surface of the Coanda vane has a radius of 50 to 300 mm. The controller adjusts 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.

First claim

What is claimed is:

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 front panel defining a front surface of the air-conditioning indoor unit;
a…
