Abstract: An air conditioner indoor unit includes a housing, a panel, a fan assembly, a first air guide assembly, and a first driving assembly. The panel includes a first air outlet. The first air guide assembly is located on a side of the panel away from the housing, and a second air outlet is constituted between an edge of the first air guide assembly and an edge of the first air outlet. The first driving assembly is configured to drive the first air guide assembly to move relative to the panel, so as to change a size of the second air outlet to adjust a flow direction of air flowing out from the second air outlet. The first air guide assembly includes a flow direction changing structure, and the flow direction changing structure is configured to move in a direction different from a moving direction of the first air guide assembly.
