Abstract

A blower includes a first tower and a second tower spaced apart from each other each having discharge ports that face each other. A gate is movably installed in at least one of the first tower or the second tower to protrude into and out of the space between the first and second towers to change a flow of air discharged out of the discharge ports. A guide motor may be configured to move the gate. The discharge ports may be provided at a rear side of the space to discharge air toward a front of the space, while the gate may be moved to cover the front side of the space to guide air upward.

First claim

What is claimed is:

1. A blower, comprising:
a first tower extending in a vertical direction, the first tower having a first wall and a first discharge port formed in the first wall;
a second tower extending in the vertical direction and spaced apart from the first tower to form a space therebetween, the second tower having a second wall facing the first wall and a second discharge port formed in the second wall;
a fan provided at a lower side of the first and second towers and configured to discharge air to an inside of the first and second towers, wherein air is discharged through the first and second discharge ports to create an airflow through the space;
at least one gate movably disposed in at least one of the first or second towers; and
at least one motor configured to move the at least one gate, and
wherein front, rear and upper sides of the space are open,
wherein the at least one gate protrudes to the front side of the space such to that selectively change an airflow direction as forward or upward,
when the at least one gate opens the front side of the space as the at least one gate is provided inside of the at least one of the first or second towers, air flows in a forward direction to be discharged out of the front side of the space, and
when the at least one gate collectively covers the front side of the space as the at least one gate protrudes to the space, air is guided along an inner surface of the at least one gate to be guided upward to be discharged out of the upper side of the space.

2. The blower of claim 1 ,
wherein the at least one gate includes:
a first gate provided in the first tower, and
a second gate provided in the second tower; and

wherein the at least one motor includes:
a first motor configured to move the first gate, and
a second motor configured to move the second gate.

3. The blower of claim 1 , wherein a vertical length of the at least one gate is shorter than a vertical length of the first discharge port or the second discharge port.

4. The blower of claim 2 , wherein the second gate is provided below the first gate such that the first gate is configured to cover an upper front of the space and the second gate is configured to cover a lower front of the space, and
wherein the first gate and the second gate have movement paths that are parallel to each other.

5. The blower of claim 2 , wherein a first slit is formed in the first tower, a second slit is formed in the second tower, the first gate is configured to move through the first slit, and the second gate is configured to move through the second slit.

6. The blower of claim 5 , wherein the first slit and the second slit are formed at different heights.

7. The blower of claim 6 , wherein the first tower has a first groove provided below the first slit and configured to receive an end of the second gate, and the second tower has a second groove provided above the second slit and configured to receive an end of the first gate.

8. The blower of claim 2 ,
when the first gate and the second gate are provided at a first position inside of the first and second towers, air flows in the forward direction to be discharged out of the front side of the space, and
when the first gate and the second gate are provided at a second position to collectively cover the front side of the space, air is guided along an inner surface of at least one of the first or second gates to be guided upward to be discharged out of the upper side of the space.

9. The blower of claim 8 , wherein, at the second position, an end of the first gate contacts an end of the second gate in the space.

10. The blower of claim 8 , wherein at the second position, a lower end of the first gate is in contact with an upper end of the second gate.

11. The blower of claim 8 , wherein at the second position, the first gate is provided behind the second gate.

12. The blower of claim 11 , wherein a lower end of the first gate is provided to be lower than an upper end of the second gate.

13. The blower of claim 11 , wherein a hole is formed between a lower end of the first gate and an upper end of the second gate, and air rising along the second gate is discharged through the hole.

14. The blower of claim 1 , wherein the at least one gate has a convex curvature curved toward a front of the blower.

15. The blower of claim 1 , wherein the first and second discharge ports are disposed backward from the at least one gate, and the first and second discharge ports are configured to discharge air frontward.

16. The blower of claim 1 , wherein the first discharge port is disposed near a rear end of the first wall, and the second discharge port is disposed near a rear end of the second wall, wherein the at least one gate is disposed near a front end of the first or second wall.

17. The blower of claim 16 , wherein a distance between the first wall and the second wall is shortest at a central part between the first and second discharge ports and the at least one gate.

18. The blower of claim 1 , the at least one gate is tilted toward the first and second discharge ports such that a distance between the at least one gate and the first and second discharge ports gets closer in the upward direction.

19. The blower of claim 18 , wherein the at least one gate protrudes to the space or moves into the first or second tower while tilted toward the first and second discharge ports.

20. The blower of claim 1 , when the at least one gate opens the front side of the space, an opening of the front side of the space is biased to the first wall or the second wall such that the air flowing in the forward direction is biased in left-right direction.

21. The blower of claim 1 ,
wherein the at least one gate is provided as a singular gate which is disposed in one of the first tower or the second tower, and when the singular gate covers the front side of the space based on the singular gate contacting the other of the first tower or the second tower, air is guided along the inner surface of the singular gate to be guided upward to be discharged out of the upper side of the space.
