  • Patent number: 11073302
    Abstract: This indoor unit of an air conditioner includes an indoor unit main body having an inlet and an outlet; a heat exchanger; and a cross-flow fan configured to blow out air, which has undergone heat exchange by the heat exchanger. The cross-flow fan has a blow-out flow path that is configured such that a cross-sectional area gradually increases downward, with the blow-out flow path guiding blown-out air to the outlet. When a distance in the lower wall from an intersection, where a tangent inscribing a tongue of the cross-flow fan orthogonally intersects the lower wall, to a lower end of the indoor unit main body is referred to as distance L, a ratio (L/D) of the distance L to outer diameter D of an impeller of the cross-flow fan is less than 0.05. At least part of the blow-out flow path is formed to project out of the outlet at least when air conditioning operation is performed.
