Samsung patents fan that steers airflow using two separate air paths

1. A blowing device comprising: a base portion having an accommodation space therein; an air inflow portion disposed on one side of the base portion and through which air is introduced from outside; a blowing body extending in a first direction, the blowing body comprising: a lower end defining an opening fluidly communicative with the base portion; a blocked upper end implemented as a blocking wall; and a side portion extending in the first direction and connecting between the lower end and the blocked upper end, wherein an entirety of the side portion has a cylindrical shape from the lower end to the blocked upper end; a blowing portion disposed in the base portion and configured to move the air introduced from the air inflow portion to the blowing body; a first driving motor configured to apply a driving force to the blowing portion; a separation wall disposed inside the blowing body and extending in the first direction to divide the inside of the blowing body into a first inner region and a second inner region; a first discharge portion disposed on the side portion of the blowing body and configured to discharge air accommodated in the first inner region to the outside along a first flow path; a second discharge portion disposed on the side portion of the blowing body and configured to discharge air accommodated in the second inner region to the outside along a second flow path; and a flow rate distribution portion disposed between the blowing portion and the separation wall and comprising a flow rate distributor disposed at a lower end of the separation wall and rotatable around an axis, the flow rate distribution portion being configured to distribute the air moved from the blowing portion to the first inner region and to the second inner region with rotation of the flow rate distributor around the axis adjusting relative amounts of the air moved from the blowing portion to the first inner region and from the blowing portion to the second inner region such that a direction of an airflow of mixed air is determined by a balance of forces of the air along the first flow path and the air along the second flow path, the mixed air is formed by a combination of the air along the first flow path and the air along the second flow path.
