Abstract

Disclosed is an indoor unit (10) of an air conditioner. The indoor unit comprises a housing having an air inlet (122) and an air outlet (112); a broken line shaped heat exchanger (200) forming a broken line shaped structure by connecting a plurality of rectangular plate-like heat exchange sections (210); and an axial flow fan (300). The included angle between every two adjacent rectangular plate-like heat exchange sections (210) is the same and is marked as θ. The minimum space in the horizontal direction between a fan blade (320) of the axial flow fan (300) and the broken line shaped heat exchanger (200) is L. The maximum distance between a radial edge of the fan blade (320) of the axial flow fan (300) and an axis of rotation of the axial flow fan (300) is R. A vertical space between a top edge and a bottom edge of the broken line shaped heat exchanger (200) is H. The indoor unit (10) of an air conditioner is configured to enable L and θ to satisfy a pre-set relationship and enable L and 2R / H to satisfy a pre-set relationship.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit. Background technique [0002] In traditional air-conditioning indoor units, especially wall-mounted air-conditioning indoor units, the multi-stage evaporator is wrapped around the periphery of the cross-flow fan and located on the upper side of the cross-flow fan. When the air conditioner is running, especially under high-temperature refrigeration conditions, there is a lot of condensed water on the evaporator, and water blowing will occur. Moreover, the use of cross-flow fans will generate greater noise when blowing air over a long distance. [0003] Some of the existing improved technologies use axial fans instead of cross-flow fans, and flat-plate evaporators instead of multi-stage evaporators. The heat exchange efficiency of the indoor unit is greatly limited. Contents of the invention [0004] One object of the present invention ...
