The invention relates to an
ion wind generation device and an air conditioner indoor unit. The
ion wind generation device comprises at least one
discharge module for generating
ion wind. Each
discharge module comprises a mesh
electrode and an
electrode stringer, wherein the mesh
electrode is arranged vertical to the wind supply direction of the
ion wind generation device, and has a plurality of circular meshes; the electrode
stringer is arranged at one side of the mesh electrode in a parallel manner; and the electrode
stringer is equipped with a plurality of needle electrodes. The needle tip of each
needle electrode points to the center of the corresponding mesh of the mesh electrode. The ratio of the
perpendicular distance between the needle tip of each
needle electrode and the mesh electrode to the
diameter of each mesh is any proportional value in a range of 0.1-0.3. The air conditioner indoor unit comprises a housing having at least one air supply port, wherein one or more air supply ports are provided with an opening and closing mechanism for rectification air supply; and at least one
ion wind generation device, which is arranged in the housing and is used for providing
ion wind to be sent to the one or more air supply ports.
