Abstract:
An upright air conditioner indoor unit, comprising: a housing (10); an air duct (20), the inner walls of the air duct (20) near to an air outlet (22) being of a tapered shape in which the flow cross section gradually decreases in the direction of airflow; and a flow guide part (30), arranged inside the air duct (20), and together with the tapered portion (150) of the air duct (20), defining an annular air outlet gap (15), the flow guide part (30) being used to guide airflow towards the annular air outlet gap (15) so as to cause the airflow (20) to gradually aggregate towards the center of airflow under the guidance of the inner walls of the air duct (20), and sequentially flow out of the air outlet (22) and an air blowing port (11). The flow guide part (30) is formed from a flow guide line being rotated once about a horizontal central axis, the flow guide line comprising, sequentially and smoothly connected, a convex first arc segment (segment ab), a concave second arc segment (segment bc), a convex third arc segment (segment cd), a convex fourth arc segment (segment de), and a convex fifth arc segment (segment ef). The upright air conditioner indoor unit features a stronger blowing force, and a farther blowing distance.
