Abstract
A blower is provided that may include an upper fan that generates a first air current suctioned through a first suction inlet and then discharged; a second fan provided adjacent to the first fan, wherein the second fan generates a second air current suctioned through a second suction inlet and then discharged. The first air current and the second air current may be in a same direction or different directions.
Claims20
A blower comprising:
- a first fan that generates a first air current suctioned in through a first suction inlet and then discharged;
- a second fan provided adjacent to the first fan, wherein the second fan generates a second air current suctioned in through a second suction inlet and then discharged;
- a first discharge outlet rotatably provided at an outlet of the first fan, wherein the first discharge outlet discharges the first air current in a radial direction;
- a second discharge outlet rotatably provided at an outlet of the second fan, wherein the second discharge outlet discharges the second air current in a radial direction;
- and
- a controller that controls rotation of at least one of the first discharge outlet or the second discharge outlet, to control a first discharge direction of the first air current and a second discharge direction of the second air current.

A blower comprising:
- an upper fan that generates a first air current suctioned through an upper suction inlet and then discharged;
- a lower fan provided below the upper fan, wherein the lower fan generates a second air current suctioned through a lower suction inlet and then discharged;
- a first discharge outlet rotatably provided at an outlet of the upper fan and including an inner circumferential edge having an upper set of teeth, wherein the first discharge outlet discharges the first air current through a first discharge port;
- a second discharge outlet rotatably provided at an outlet of the lower fan and including an inner circumferential edge having a lower set of teeth, wherein the second discharge outlet discharges the second air current through a second discharge port;
- a first gear motor configured to rotate a first pinion gear that interacts with the upper set of teeth;
- a second gear motor configured to rotate a second pinion gear that interacts with the lower set of teeth;
- and
- a controller that controls rotation of the first gear motor and second gear motor to rotate the first discharge outlet and the second discharge outlet, to control a first discharge direction of the first air current and a second discharge direction of the second air current.
