AIR CONDITIONER INDOOR UNIT

WIPO Patent Application WO/2019/057037

A1

An air conditioner indoor unit, comprising: a housing (100), which is in the shape of a hollow cylinder having a central axis extending along the front-rear direction, a rear end being an air inlet end, a front end being an air outlet end; a heat exchange apparatus (200), which is arranged within the housing (100) and used for performing heat exchange with air entering the housing (100) from the air inlet end to form heat exchange air; an air supply assembly, which comprises: at least one axial flow fan (320), which is arranged within the housing (100) such that a rotation axis of the axial flow fan (320) extends along the front-rear direction, the axial flow fan (320) being used for causing the heat exchange air to be blown out from the air outlet end; an air guide ring (500), which is coaxially sleeved with the housing (100) on an outer peripheral front portion of the housing (100), the inner diameter of the air guide ring (500) being greater than the outer diameter of the housing (100) so as to define an air guide channel (501) with an outer peripheral surface of the housing (100), thereby allowing indoor air to flow forward via the air guide channel (501) to mix with the heat exchange air. The air conditioner indoor unit has a large air volume and low noise, and implements mixed air supply, thereby increasing air supply comfort.
