Blowing device and blowing device operating method

A blowing device, comprising:

• a base;
• an air inflow portion aside the base and through which air is introduced;
• a body extending in a first direction, being provided as a conduit 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 drivable to move the air introduced from the air inflow portion to the body;
• a separation wall inside the body and extending in the first direction to divide the inside of the body into first and second inner regions;
• first and second discharge portions disposed on the side portion of the body and configured to discharge air accommodated in the first and second inner regions along a first flow path and a second flow path, respectively;
• and
• a flow rate distributor between the blowing portion and a lower end of the separation wall and rotatable around an axis,
• the flow rate distributor being configured to distribute the air moved from the blowing portion to the first and second inner regions 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.

A blowing device operating method, comprising:

• operating a first drive motor;
• providing a body having a lower end with an opening and a blocked upper end;
• transmitting air introduced into an air inflow portion to first and second inner regions of the body via the opening of the lower end, an entirety of the body having a cylindrical shape from the lower end to the blocked upper end;
• distributing a flow rate of the air transmitted to each of the first and second inner regions using a flow rate distributor;
• adjusting an angle at which the flow rate distributor rotates to adjust relative amounts of the air transmitted to the first inner region and to the second inner region;
• discharging air of a first flow path using a first discharge portion aside the body and configured to discharge air accommodated in the first inner region;
• discharging air of a second flow path using a second discharge portion aside the body and configured to discharge air accommodated in the second inner region;
• moving the air of the first flow path and the air of the second flow path along an outer circumferential surface of the body;
• and
• forming an airflow of mixed air by mixing the air of the first and second flow paths,
• wherein a direction of the 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.
