The upper hole 98a and the lower hole 98b can change the rotational movement of the upper link 96a and the lower link 96b into the linear movement of the connector 98 and the plate 92.

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

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

The airflow conversion guider 102 can prevent the connector 98 from being sagging in the direction of gravity even if the upper link 96a and the lower link 96b move along the upper hole 98a and the lower hole 98b. there is. The air flow conversion guider 102 may be disposed at the top and bottom of the connector 98, respectively.

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

And when the air flow converters (90a, 90b) are inserted into the slit (69) of the first upper case (60), the upper links (96a, 96b) and lower links (96a, 96b) are connected to the first upper case (60). It can be arranged approximately perpendicular to the surface formed.

Referring to FIG. 5, the upper motor 94a and the lower motor 94b are fixed to the inside of the first upper case 60 through the upper bracket 104a and the lower bracket 104b.

Referring to Figure 7, the air flow converters (90a, 90b) may provide a first position (P1) where the outer end forms a flat surface with the first upper case (60). Referring to Figure 8, the air flow converters (90a, 90b) may be inserted into the inside of the first upper case (60) to provide a second position (P2).

The air flow converters (90a, 90b) do not protrude to the outside of the first upper case (60) at the first position (P1) and close the slit (69). That is, referring to FIG. 7, when the air flow converters 90a and 90b are located at the first position P1, the outer surface of the first upper case 60 is formed to be smooth.

Therefore, as shown in (a) of FIG. 9, the air discharged through the inner discharge port 64 and the main discharge ports 80a and 80b flows forward along the outer surface of the first upper case 60, forming a Coanda effect. You can.

The air discharged through the main discharge ports (80a, 80b) moves forward along the outer surface of the first upper case (60) by the guide plates (78a, 78b). At this time, the air flowing forward may flow along the outer surface of the first upper case 60 and flow toward the front due to the Coanda effect.

Referring to (b) of FIG. 9, the air around the first upper case 60 can also flow by the air discharged through the main discharge ports 80a and 80b.

When air is discharged through the main discharge ports (80a, 80b) with the first slit (69a) and the second slit (69b) closed, the air discharged from the first main discharge port (80a) is one part of the upper case. The air flows along the side (the first left upper case, 60a in this embodiment) and then flows to the front end of the upper case, and the air discharged from the second main outlet (80b) flows to the other side of the upper case (in this embodiment, the first left upper case, 60a). 1 It may flow along the right upper case, 60b) and then flow to the front end of the upper case.

At this time, the air flowing along one side and the other side due to the Coanda effect joins at the front end of the upper case and is then discharged to the front of the upper case 60. As shown in Figure 9 (a) and Figure 9 (b), the flow of air discharged when the slits 69a and 69b are closed is called concentrated air flow.

When air is discharged through the main outlet (80a) with the first slit (69a) open, the air discharged from the first main outlet (80a) is discharged from one side of the upper case (in this embodiment, the first left side). While flowing along the upper case (60a), it interferes with the air discharged from the first slit (69a) and flows in a direction away from one side.

When air is discharged through the main outlet (80b) with the second slit (69b) open, the air discharged from the second main outlet (80b) flows to the other side of the upper case (in this embodiment, the first right side). 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 wide airflow.

In this embodiment, both the first slit 69a and the second slit 69b are opened through an air flow 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) can be opened through an air flow converter. For example, when the first slit (69a) is opened and the second slit (69b) is closed, discharge air biased toward one side (left direction) of the upper case 60 can be formed, which is referred to as the first deflection. It is called air current. In contrast, when the first slit (69a) is closed and the second slit (69b) is opened, discharge air biased toward the other side (right direction) of the upper case 60 can be formed, which is called a second deflection air flow. It is said that

13 to 16, the arrangement of the inner damper 110 resulting from the operation of the second motor 138 and the discharge airflow of the air clean fan 10 formed accordingly will be described.

By operating the second motor 138, the pair of covers 112a and 112b can be placed in contact with each other or spaced apart from each other.

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

Additionally, as shown in FIG. 16 , the inner ends 114d of each cover 112a and 112b may be placed in a fourth position P4 where they contact 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 converters (90a, 90b). It is based on .

The third position (P3) and the fourth position (P4) can be applied independently of the first position (P1) and the second position (P2).

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

Accordingly, the air flowing upward due to the operation of the blowing fan 30 flows through the hole 128 formed in the first support plate 126 and the space formed inside the cover body 72 at the front and rear of the supporter 124. It can flow into the second flow passage 62 of the first upper case 60. 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 along the outer surface of the first upper case 60 by the first guider 74. can do.

Referring to Figures 15 and 16, when the inner damper 110 is in the fourth position (P4), the covers (112a, 112b) open the sub discharge port (83). When the inner damper 110 is in the fourth position P4, the inner ends 114d of the pair of covers 112a and 112b are placed in contact with each other. Accordingly, a space through which air flows is formed between the side ends 114a of the covers 112a and 112b and the inner surface of the cover body 72.

The blowing fan 30 rotates to discharge air in the upper centrifugal direction. Accordingly, the air flowing inside the cover body 72 mainly forms an airflow on the inner surface of the cover body 72. Accordingly, air flowing along the cover body 72 may flow into the sub-discharge port 83 along the inner surface of the cover body 72. However, some of the air flow occurs in the space between the covers (112a, 112b) and the sub outlet 83, the front and rear ends (114b) and rear ends (114c) of the covers (112a, 112b), and the cover body (72). It can flow into the second flow passage 62 inside the first upper case 60 through the space between them.

Accordingly, some flow of air may be formed through the inner discharge port 64, but the flow rate and velocity of the air flowing through the sub outlet 83 are greater than those of the air flowing through the inner discharge port 64. Since it is formed quickly, a discharge airflow can be formed through the sub-discharge port 83.

The air flowing through the sub-discharge port 83 can travel upward along the outer surface of the first upper case 60 by the second guider 84.
