The connector 98 has a shape that surrounds a portion of the plate 92 , and an LED lamp (not shown) may be disposed in a space into which the plate 92 is inserted. The LED lamp may be disposed at the end of the plate 92 that is inserted into the connector 98 . The plate 92 is formed of a transparent material, and can transmit the light irradiated from the LED lamp to the outside.

The airflow conversion guider 102 may guide the moving direction of the connector 98 . The airflow conversion guide 102 guides the plate 92 to move in a direction perpendicular to the link holes 98a and 98b. The airflow conversion guide 102 is connected to the protrusion 100 protruding from the connector 98 so as to be movable in a straight line. The protrusion 100 formed on the connector 98 extends in a direction perpendicular to the link holes 98a and 98b.

Airflow conversion guider 102, even if the upper link (96a) and the lower link (96b) moves along the upper hole (98a) and the lower hole (98b), the connector 98 can be prevented from sagging in the direction of gravity. there is. The airflow conversion guider 102 may be disposed on the upper and lower portions of the connector 98 , respectively.

The upper link 96a and the lower link 96b rotate in different directions. That is, when the airflow transducers 90a and 90b are disposed inside the first upper case 60 , the upper links 96a and 96b are disposed toward the upper side, and the lower links 96a and 96b are disposed toward the lower side. .

And when the airflow transducers (90a, 90b) are inserted into the slit 69 of the first upper case 60, the upper links (96a, 96b) and the lower links (96a, 96b), the first upper case (60) It may be disposed approximately perpendicular to the surface formed by the .

When air is discharged through the main discharge port 80b in a state in which the second slit 69b is opened, the air discharged from the second main discharge port 80b is the other side of the upper case (the first right side in this embodiment) While flowing along the upper case (60b), it interferes with the air discharged from the second slit (69b) and flows in a direction away from the other side.

In this way, the flow in the direction away from one side and the other side of the upper case is called a wide airflow.

In this embodiment, both the first slit 69a and the second slit 69b are opened through the airflow converter to provide the wide airflow shown in FIGS. 10(a) and 10(b).

Although not shown, only one of the first slit 69a and the second slit 69b may be opened through the airflow converter. For example, when the first slit 69a is opened and the second slit 69b is closed, the discharge air that is biased toward one side (left direction) of the upper case 60 can be formed, which is the first deflection called air current Contrary to this, when the first slit 69a is closed and the second slit 69b is opened, the discharge air biased toward the other side (right direction) of the upper case 60 can be formed, which causes the second deflection airflow. say

The arrangement of the inner damper 110 due to the operation of the second motor 138 and the discharge air flow of the air clean fan 10 formed accordingly will be described with reference to FIGS. 13 to 16 .

By the operation of the second motor 138 , the pair of covers 112a and 112b may be disposed in contact with each other or disposed to be spaced apart from each other.

For example, as shown in FIG. 14 , the pair of inner dampers 110 may be disposed at the third position P3 in which the inner ends 114d of each of the covers 112a and 112b are spaced apart from each other.

Also, as shown in FIG. 16 , the inner ends 114d of each of the covers 112a and 112b may be disposed at a fourth position P4 in contact with each other.

The third position P3 and the fourth position P4 are based on the arrangement of the inner damper 110, and the first position P1 and the second position P2 are the arrangement of the airflow transducers 90a and 90b. is based on

The third position P3 and the fourth position P4 may be independently applied regardless of the first position P1 and the second position P2 .

13 to 14 , when the inner damper 110 is in the third position P3 , the covers 112a and 112b close the sub discharge port 83 . When the inner damper 110 is at the third position P3 , the covers 112a and 112b are disposed below the grill 88 disposed in the sub discharge port 83 . That is, when the inner damper 110 is at the third position P3 , the inner damper 110 blocks the air flowing upward by the blower fan 30 from flowing to the sub outlet 83 .

Accordingly, the air flowing upward due to the operation of the blower fan 30 is a space formed inside the hole 128 formed in the first support plate 126 and the cover body 72 in front and rear of the supporter 124 . It may flow into the second flow path 62 of the first upper case 60 through the . The air flowing along the flow path of the first upper case 60 is discharged rearward through the inner discharge port 64 , and flows forward while riding the outer surface of the first upper case 60 by the first guider 74 . can do.

15 to 16 , when the inner damper 110 is at the fourth position P4 , the covers 112a and 112b open the sub-discharge port 83 . When the inner damper 110 is in the fourth position P4, the pair of covers 112a and 112b are disposed so that their respective inner ends 114d are in contact with each other. Accordingly, a space in which air flows is formed between the side ends 114a of the covers 112a and 112b and the inner surfaces of the cover body 72 .

The blower fan 30 discharges air in an upper centrifugal direction by rotation. Accordingly, the air flowing inside the cover body 72 mainly forms an airflow on the inner surface of the cover body 72 . Accordingly, the air flowing along the cover body 72 may flow to the sub-discharge port 83 along the inner surface of the cover body 72 . However, a portion of the air flow is caused by the space between the covers 112a and 112b and the sub-discharging port 83, the front end 114b and the rear end 114c of the covers 112a and 112b, and the cover body 72. It may flow to the second flow path 62 inside the first upper case 60 through the interspace.

Accordingly, although the flow of air through the inner discharge port 64 may be partially formed, the flow rate and flow velocity of the air flowing through the sub discharge port 83 are greater than the flow rate and flow rate of the air flowing through the inner discharge port 64 . Since it is formed quickly, the discharge air flow through the sub discharge port 83 may be formed.

The air flowing through the sub-discharging port 83 may ride on the outer surface of the first upper case 60 by the second guider 84 and flow upward.
