Specifically, the laminar flow motor 20 drives the plurality of annular disks to rotate, so that the plurality of annular disks contact with air between each other and move with each other, and the air boundary layer 13 close to the surfaces of the plurality of annular disks is driven by the plurality of rotating annular disks to rotate from inside to outside due to the viscous effect to form laminar flow wind. A plurality of air outlets 12 are formed in the gaps between the plurality of annular disks, each air outlet 12 can supply air for 360 degrees, and laminar air discharged from the air outlets 12 is blown out to the environment outside the indoor unit 300 of the floor air conditioner through the laminar air outlet 321.

The connecting member 40 may be blade-shaped or rod-shaped. The laminar flow motor 20 may also be configured to: the driving disk 30 is directly driven to rotate, and the driving disk 30 drives the plurality of annular disks 10 to rotate. That is, the laminar flow motor 20 configured to rotate the plurality of annular discs 10 is dependent on the laminar flow motor 20 first rotating the driving disc 30, and then the driving disc 30 rotates the plurality of annular discs 10.

The variable y in τ (y) and u (y) refers to the height of the cross-section of the boundary layer 13 in the direction perpendicular to the direction of movement, and L is the distance between a point on the inner circumference of the annular disk 10 and a point on the surface of the annular disk 10.τ (y) is the distribution of viscous shear forces experienced at this distance L at a cross-sectional height y of the boundary layer 13 of air; u (y) is the velocity profile at this distance L for a cross-section of the air boundary layer 13 having a height y.
