Meanwhile, in this drawing, the

flow control devices

For example, the fan 21 includes a first fan (not shown) that generates a flow so that air flows into the first channel 81, and a second fan that generates a flow so that air flows into the second channel 82. (not shown) may be included. A first fan (not shown) may be disposed adjacent to the first nozzle inlet 71, and a second fan (not shown) may be disposed adjacent to the second nozzle inlet 72.

The user may adjust the flow rate for the first channel 81 and the second channel 82 by controlling the operation of the first fan (not shown) and the second fan (not shown).

In addition, if the flow rate of air flowing into the first channel 81 and the second channel 82 can be adjusted, the flow rate control device can be implemented in various ways.

The nozzle 50 may include a nozzle discharge portion 63 that is provided to discharge air flowing into the nozzle channel portion 62 toward the outside. The nozzle discharge unit 63 may include a nozzle discharge port 69 that discharges air to the outside.

The nozzle outlet 69 can synthesize the air flowing into the first channel 81 and the second channel 82 and discharge it together to the outside. The air moving along the first channel 81 and the air moving along the second channel 82 may be synthesized and discharged through the nozzle outlet 69 as a single flow.

The nozzle discharge unit 63 may include a guide unit 64 that guides the direction of air. The guide portion 64 may be disposed adjacent to the nozzle outlet 69. The guide part 64 may include a first guide part 65 and a second guide part 66.

The first guide portion 65 may be disposed adjacent to the first channel 81. The first guide unit 65 may guide air introduced into the first channel 81 in the first direction (A). Air flowing into the first channel 81 may be discharged in the first direction A while passing through the first guide part 65.

At this time, if the +Y axis is defined as 0 degrees, the angle between the +Y axis and the +X axis is +90 degrees, and the angle between the +Y axis and the -X axis is defined as -90 degrees, the angle formed by the first direction (A) is can be +30 degrees or -30 degrees.

To explain this drawing as an example, the first direction A may be a direction facing approximately -30 degrees.

The second guide portion 66 may be disposed adjacent to the second channel 82. The second guide unit 66 may guide air introduced into the second channel 82 in the second direction (B). Air flowing into the second channel 82 may be discharged in the second direction (B) while passing through the second guide portion 66.

At this time, the second direction (B) may be a different direction from the first direction (A). The second direction (B) may be symmetrical with respect to the first direction (A) and the Y axis. The second direction (B) may be opposite to the first direction (A). For example, if the angle formed by the first direction (A) is +30 degrees, the angle formed by the second direction (B) is -30 degrees, and if the angle formed by the first direction (A) is -30 degrees, the angle formed by the second direction (B) is -30 degrees. The angle formed by (B) may be +30 degrees.

To explain this drawing as an example, the second direction B may be a direction facing approximately +30 degrees. However, the present disclosure is not limited to this, and the first direction (A) and/or the second direction (B) may be provided at various angles.

The first guide part 65 and/or the second guide part 66 may include a curved surface 67. The curved surface 67 may be prepared to have a predetermined curvature. The curved surface 67 may be provided to be convex toward the partition wall 83.

The curved surface 67 may include a first curved surface 67a provided on the first guide part 65 and a second curved surface 67b provided on the second guide part 66. The first curved surface 67a and the second curved surface 67b may be provided to face each other. The first curved surface 67a and the second curved surface 67b may be provided to be convex toward each other.

The curved surface 67 may be arranged to cause a Coanda effect. Air passing through the first channel 81 may come into close contact with the first curved surface 67a and flow along the first curved surface 67a due to the Coanda effect. At this time, it can be directed in the first direction (A) according to the curvature of the first curved surface (67a).

At this time, among the air passing through the first channel 81 or the second channel 82, the air passing through the channel with a large flow rate may attract the air passing through the channel with a low flow rate. For example, if more air flows into the first channel 81 than the second channel 82 through adjustment of the

flow control devices

20, 31, and 35, the momentum of the air passing through the first curved surface 67a Since the momentum of the air passing through the second curved surface (67b) is greater, the air passing through the first curved surface (67a) is in close contact with the first curved surface (67a) and pulls the air passing through the second curved surface (67b), resulting in the final Air deflected toward the first curved surface 67a is discharged through the nozzle discharge port 69.

Conversely, if more air flows into the second channel 82 than the first channel 81, the air biased toward the second curved surface 67b is discharged through the nozzle outlet 69.

If all of the air is introduced into the first channel 81, the direction of the air discharged through the nozzle outlet 69 may be in the first direction (A), and all of the air is introduced into the second channel 82. If so, the direction of the air may be the second direction (B).

In addition, by adjusting the flow rate ratio of the air flowing into each of the first channel 81 and the second channel 82, the direction of the air discharged from the nozzle outlet 69 is changed to the first direction (A) and the second direction (B). ) can be continuously adjusted between.

4 as an example, since the flow rate of the air (F2) flowing along the second channel 82 is greater than the flow rate of the air (F1) flowing along the first channel 81, the second channel 82 The air (F2) flowing along may attract the air (F1) flowing along the first channel (81). Therefore, overall, the air can be discharged in a direction close to the second direction (B).

That is, the air discharged through the nozzle outlet 69 may be discharged toward the third direction. The third direction may be the first direction (A) or the second direction (B), or may be between the first direction (A) and the second direction (B). For example, the third direction may be provided to form a continuous angle from +30 degrees to -30 degrees.

Therefore, by adjusting the flow rate of the air (F1, F2) flowing into the first channel 81 and the second channel 82, the direction of the air discharged from the nozzle outlet 69 can be continuously adjusted.

The first guide portion 65 and/or the second guide portion 66 may include an inclined surface 68 . The inclined surface 68 may be provided to have a predetermined inclination.

The inclined surface 68 may be provided to be inclined toward the nozzle outlet 69. The inclined surface 68 may be inclined toward the partition wall 83 as it becomes closer to the nozzle outlet 69.

The inclined surface 68 may include a first inclined surface 68a provided on the first guide part 65 and a second inclined surface 68b provided on the second guide part 66. The first inclined surface 68a and the second inclined surface 68b may be provided to face each other. The first inclined surface 68a and the second inclined surface 68b may be inclined toward each other as they approach the nozzle discharge port 69.

The air can be directed in the first direction (A) by the first inclined surface (68a). In this case, if this drawing is used as an example, the first direction (A) can be directed at +30 degrees. The second direction (B) may be directed to -30 degrees.

However, the present disclosure is not limited to this, and the first direction (A) and/or the second direction (B) in which air is discharged by the inclined surface 68 may be provided at various angles.

Air passing through the first channel 81 or the second channel 82 may be discharged through the nozzle outlet 69 along the direction in which the air passing through the channel with a large flow rate flows.

For example, if more air is introduced into the first channel 81 than the second channel 82 through adjustment of the

flow control devices

20, 31, and 35, the air ultimately directed in the first direction A is It is discharged through the nozzle outlet (69). That is, the air discharged through the nozzle outlet 69 may be discharged in a third direction, and the third direction may be either the first direction (A) or the second direction (B).
