In the present embodiment, the front end 222a and the rear end 212b are brought into close contact, but not in contact.

And when the vane module 200 forms a horizontal wind in the discharge step P1, the first vane 210 and the second vane 220 are connected to operate like one vane, so that the airflow intensity of the horizontal wind is increased. I can. That is, since the discharge air is guided in a horizontal direction along the upper surface of the second vane 220 and the upper surface of the first vane 210, the directionality of the discharge air is further strengthened compared to forming a horizontal wind with one vane. I can make it.

When forming the horizontal wind, the second vane 220 is disposed to be inclined more vertically than the first vane 210.

In the case of the horizontal wind, when viewed from the side, it is advantageous that the first vane 210 is positioned below the discharge port 102, and the second vane 220 is disposed to overlap the discharge port 102. .

In the discharge step P1 state, the second vane 220 is rotated in place around the second vane shaft 221, but the first vane 210 is connected to the driving link 240 and the first vane link 250 Since it is assembled, it rotates (swings) in the air discharge direction.

When progressing from P0 to P1, the second vane 220 rotates around the second vane shaft 221, and the first vane 210 moves downward while advancing in the air discharge direction, and the first vane The front end 212a is rotated in the first direction (clockwise in the drawing).

The first vane 210 can be moved to the lower side of the discharge port 102 through rotation of the driving link 240 and the first vane link 250, and the first vane 210 is disposed approximately horizontally. I can make it. Since the vanes of the conventional indoor unit are rotated in place, the same arrangement as the first vane 210 of the present embodiment cannot be implemented.

When the vane motor 230 rotates the driving link 240 in the second direction (counterclockwise) in the stop step P0, the second vane link 260 coupled to the driving link 240 is also the driving link. It is rotated in response to 240.

Specifically, when the stop step P0 is changed to the discharge step P1, the driving link 240 rotates counterclockwise, and the first vane link 210 rotates counterclockwise according to the rotation of the driving link 240 Is rotated, and the second vane link 220 is lowered while being rotated relative to each other.

Since the second vane 220 is assembled so as to be relatively rotatable with the second vane shaft 221 and the second vane link 260, the second vane is lowered by the second vane link 220. 220 is rotated clockwise around the second vane shaft 221.

In order to form the horizontal wind, when changing from the stop step P0 to the discharge step P1, the rotation directions of the first vane 210 and the second vane 220 are opposite.

In the discharge step P1, the vane motor 230 is rotated by 73 degrees (P1 rotation angle), and by the rotation of the vane motor 230, the first vane 210 has an inclination of approximately 13 degrees (the first vane P1 inclination) And the second vane 220 forms an inclination of approximately 52 degrees (the second vane P1 inclination).

In the discharge step P1, the positional relationship of the axes forming the rotation center of each link is as follows.

First, unlike the P0, the second joint portion 217 and the first joint portion 216 of the first vane 210 are disposed to be inclined toward the front in the air discharge direction. When viewed from the side, the third joint part 226 of the second vane 220 is disposed at the rearmost, the first joint part 216 is disposed at the most front, and the second joint part 217 Is disposed between the first joint portion 216 and the third joint portion 226.

The 2-1 vane link shaft 261 is positioned lower than the second vane shaft 221, and the first driving link shaft 241 is lower than the 2-1 vane link shaft 261 It is positioned, and the 1-1 vane link shaft 251 is positioned lower than the first drive link shaft 241.

In the P1 state, the third joint portion 226, the second joint portion 217, and the first joint portion 216 are arranged in a row, and the arrangement direction faces forward and downward in the air discharge direction. When providing the discharge step P1, the second vane shaft 221, the 2-1 vane link shaft 261, the first drive link shaft 241, and the 1-1 vane link shaft 251 are aligned Is placed.

Depending on the embodiment, the third joint portion 226, the second joint portion 217, and the first joint portion 216 may not be arranged in a line.

In addition, as for the second vane shaft 221, the third joint part 226, the second joint part 217, and the first joint part 216 may be arranged in a line. In this case, the second vane shaft 221 is located on the rear side of the third joint part 226.

In the P1 state, the first vane 210 and the second vane 220 provide horizontal wind. The horizontal wind does not mean that the air discharge direction is exactly horizontal. In the horizontal wind, the first vane 210 and the second vane 220 are connected like a single vane, and the discharged air is transferred in the horizontal direction through the connection of the first vane 210 and the second vane 220. It means the angle at which it flows farthest

In the discharge step P1 state, a distance S1 between the front end 222a of the second vane 220 and the rear end 212b of the first vane 210 may be formed to a minimum.

In the horizontal wind, the air guided by the second vane 220 is guided to the first vane 210. When the discharged air flows in a horizontal wind through the P1 state, the flow distance of the air can be maximized.

Since the discharge passage 104 is formed in the vertical direction, the inclination of the second vane 220 close to the suction port 101 is formed to be steeper than the inclination of the first vane 210.

And in the state of the discharge step P1, the 1-1 vane link shaft 251 of the first vane link 250 is located below the 1-2 vane link shaft 252.

In the discharge step P1 state, the 2-1 vane link shaft 261 of the second vane link 260 is located under the 2-2 vane link shaft portion 262.

In the discharge step P1 state, the first drive link shaft 241 of the drive link 240 is positioned below the second drive link shaft 242 and the core link shaft 243.

In the discharge step P1 state, with respect to the vertical direction, the third joint part 226 is located at the uppermost side, the first joint part 216 is located at the lowest side, and the second joint part 217 is Is located in between.

In the discharge step P1 state, the first joint part 216 and the second joint part 217 are positioned between the core link shaft 243 and the 1-2 vane link shaft 252. When providing the discharge step P1, the first driving link shaft 241 and the 1-1 vane link shaft 251 are positioned between the core link shaft 243 and the 1-2 vane link shaft 252 do.

And in the state of the discharge step P1, the first drive link shaft 241 and the 1-1 vane link shaft 251 are located under the suction panel 320. In the state of the discharge step P1, the first drive link shaft 241 and the 1-1 vane link shaft 251 are located below the discharge port 102. The 2-1 vane link shaft 261 is located across the boundary of the discharge port 102.

Due to this arrangement, in the state of the discharge step P1, the first vane 210 is located below the discharge port 102. In the state of the discharge step P1, the front end 222a of the second vane 220 is located under the discharge port 102, and the rear end 222b is located above the discharge port 102.

Next, in the state of the discharge step P1, the relative positions and directions of the links are as follows.

The longitudinal direction of the first driving link body 246 is defined as D-D'. The longitudinal direction of the first vane link 250 is defined as L1-L1'. The longitudinal direction of the second vane link 260 is defined as L2-L2'.

In the discharge step P1 state, the first vane link 250, the second vane link 260, and the first driving link body 246 are arranged in the same direction. In the present embodiment, the first vane link 250, the second vane link 260, and the first driving link body 246 are all arranged in the vertical direction in the discharge step P1 state.

Specifically, L1-L1' of the first vane link 250 is disposed substantially vertically, and L2-L2' of the second vane link 260 is also disposed substantially vertically. D-D' of the first driving link body 246 is disposed to face downward in the air discharge direction.

In the discharge step P1 state, the first vane 210 is located under the discharge port 102, and the front end 222a of the second vane 220 is located under the discharge port 102. That is, in the horizontal wind, only a part of the second vane 220 is located outside the discharge port 102, and the entire first vane 210 is located outside the discharge port 102.

In the state of the discharge step P1, the front end 212a of the first vane 210 is positioned on the front side of the discharge port 102 relative to the front edge 102a of the discharge port 102.

<Circulation prevention structure at discharge step P1>

The discharge passage 104 is disposed in the upper discharge passage 104-1 disposed in the case housing 110, the front panel 300, and communicates with the upper discharge passage 104-1, and the It includes a lower discharge passage (104-2) located below the upper discharge passage (104-1).

In this embodiment, the lower discharge passage 104-2 is located above the discharge port 102 of the front panel 300. The lower discharge passage 104-2 may be formed through components constituting the front panel 300.

In this embodiment, the lower discharge passage 104-2 includes a side cover 314 positioned at the front side in the air discharge direction, a drain pan 132 positioned at the rear side in the air discharge direction, and are respectively positioned at both sides of the air discharge direction. It is formed by the first module body 310 and the second module body 320.

Unlike the present embodiment, the upper and lower sides are opened to provide the lower discharge passage 104-2, and separate parts are installed so that the front, rear, and both sides are blocked.

In this embodiment, the inner side of the side cover 314 providing the lower discharge passage 104-2, the outer side of the drain pan 132, the link installation part 404 of the first module body 410 and the second The link installation part 404 of the module body 420 is defined as a discharge guide 360.

For convenience of explanation, the side cover 314 side is defined as the front side, the drain pan 132 side as the rear side, the first module body 410 side as the left direction, and the second module body 420 side as the right direction. do.

So, the inner side of the side cover 314 is the front discharge guide 361, the outer side of the drain pan 132 is the rear discharge guide 370, and the inner side of the link installation part 404 is the side discharge guide 362. Is defined as

The upper and lower surfaces of the discharge guide 360 are opened. The upper side of the discharge guide 360 communicates with the upper discharge passage 104-1. The lower side of the discharge guide 360 forms a discharge port 102.

In this embodiment, the discharge guide 360 may be disposed for each discharge port 102.

Since the discharge step P1 provides horizontal wind, discharge air may be discharged between the bottom surface 222c of the second vane 220 and the rear discharge guide 370.

The gap between the bottom surface 222c of the second vane 220 and the rear discharge guide 370 is defined as a leakage space LS. As the flow rate of air discharged into the leakage space LS decreases, the flow rate of air guided by the first vane 210 and the second vane 220 increases.

Some of the discharged air enters the leakage space LS through the upper side of the leakage space LS, and is discharged through the lower side of the leakage space LS.

When the amount of air introduced into the leakage space LS increases, there is a problem in that the amount of discharged air returned to the inlet 101 increases. The phenomenon in which the air discharged from the discharge port 102 is directly sucked into the suction port 101 is defined as a circulating wind.

When the ventilation is generated, dew condensation occurs on the edge of the suction panel 320 where the ventilation is generated. Since the temperature of the air discharged to the discharge port 102 is lower than that of the indoor air, the ventilation lowers the temperature at the edge of the suction panel 320, and condensation may occur.

In this way, the discharged air flowing into the leakage space LS causes various problems. Particularly, as the distance W between the outer edge of the suction port 101 and the grill side border 325 is narrower, a ventilation may be generated. In order to prevent the ventilation, if the gap W is increased, the area of the suction port 101 is narrowed.

In this embodiment, the structure of the discharge guide 360 is improved to provide a structure capable of minimizing the ventilation. By improving the structure of the rear discharge guide 370 disposed on the suction port 101 side of the discharge guide 360, it is possible to minimize the ventilation.

The rear discharge guide 370 is disposed between the discharge port 102 and the suction port 101, a vertical guide body 372 disposed vertically in an up-down direction, and a lower side of the vertical guide body 372, , It is formed to protrude from the lower side of the vertical guide body 372 to the side of the second vane 220, and includes a lower guide body 374 forming a discharge port 102.

A surface of the vertical guide body 372 and the lower guide body 374 exposed to the discharge passage 104 is defined as a guide surface 375. In this embodiment, the guide surface 375 may be a side surface of the drain pan 132 on the discharge passage side.

The guide surface 375 includes a first guide surface 375a, a second guide surface 375b, and a third guide surface 375c formed on the outer surface of the vertical guide body 372, and the lower guide body 374 ) And a fourth guide surface (375d) formed on the outer surface.

The first guide surface 375a is located at the uppermost side, the second guide surface 375b is located below the first guide surface 375a, and the third guide surface 375c is located at the lower side of the second guide surface 375b. And the fourth guide surface 375d is located under the third guide surface 375c.

The first guide surface 375a is formed vertically and is positioned above the second vane 220. The first guide surface 375a forms the lower discharge passage 104-2.

The third guide surface 375c is formed vertically in the vertical direction. At least a portion of the third guide surface 375c is positioned at the same height as the second vane 220. A leakage space LS is positioned between the third guide surface 375c and the bottom surface 222c of the second vane 220.

The third guide surface 375c is positioned further toward the suction port 101 than the first guide surface 375a. That is, when viewed from a side cross-section, the first guide surface 375a and the third guide surface 375c form an expanded depth T in the horizontal direction.

The expansion depth T has an effect of expanding the cross-sectional area of the leakage space LS.

In this embodiment, with respect to the vertical direction, the upper end 376a of the third guide surface 375c is positioned higher than the second vane shaft 221.

The second guide surface 375b connects the lower end of the first guide surface 375a and the upper end 376a of the third guide surface 375c. The second guide surface 375b may be formed as a smooth curved surface or an inclined surface. The upper end of the second guide surface 375b faces the discharge passage 104 and the lower end faces the suction port 101.

The fourth guide surface 375d is connected to the lower end 376b of the third guide surface 375b. The fourth guide surface 375d is formed in a round shape toward the discharge port 102.

An end 376 is formed at the lower end 376c of the fourth guide surface 375d. The end 376 is formed to be concave toward the discharge port 102 from the lower end 376c of the fourth guide surface 375d.

The lower end 376c of the fourth guide surface 375d protrudes further toward the second vane 220 than the first guide surface 375a. The extension line of the vertically formed first guide surface 375a crosses the fourth guide surface 375d.

The second guide surface 376b, the third guide surface 376c, and the fourth guide surface 375d depressed toward the suction passage 103 by an expansion depth T have an effect of expanding the leakage space LS. .

With respect to the vertical direction, the rear end 222c of the second vane is located at the height of the recessed expansion depth T.

With respect to the horizontal direction, the distance between the rear end 222a of the second vane and the discharge guide 370 is longer than the distance between the lower end 376c of the discharge guide and the bottom surface 222c of the second vane. .

In this embodiment, the cross section of the leakage space LS is formed to become narrower toward the lower side. The area of the inlet LS1 of the leakage space LS is the widest, and the area of the outlet LS2 is the narrowest.

In the horizontal direction, the cross-sectional area between the rear end 222a of the second vane and the discharge guide (specifically, the third guide surface) is the lower end of the discharge guide (specifically, the lower end of the fourth guide surface) and the second vane. It is formed wider than the cross-sectional area between the bottom surfaces 222c of the 2 vanes.

In this way, by forming the area of the leakage space LS to be narrowed in the air flow direction, it is possible to suppress the discharged air from entering the leakage space LS. Since the area becomes narrower as the air flow direction increases, the pressure increases.

By gradually reducing the cross-sectional area of the leakage space LS, the pressure of the outlet LS2 can be increased rather than the pressure of the inlet LS1.

Among the discharge steps P1 to P6, in the discharge step P1, the leakage space LS is formed the largest, and the cross-sectional area of the leakage space outlet LS2 is also formed the largest.

In the discharge step P1, the cross-sectional area in the vertical direction of the leakage space LS is formed to gradually decrease, thereby minimizing the ventilation. In the discharge steps P2 to P6, since the second vane 220 is closer to the rear discharge guide 370, less air enters the leakage space LS.

<Discharge step P2>

In the horizontal wind state of the discharge step P1, the driving link 240 may be rotated in a second direction opposite to the first direction (counterclockwise in the drawing of this embodiment) to form the discharge step P2.

When the vane module provides any one of the discharge steps P2 to P5, the rear end 212b of the first vane is positioned higher than the front end 222a of the second vane, and the second vane It is positioned equal to or lower than the 1 vane link shaft 261.

And when the vane module provides any one of the discharge steps of P2 to P5, a clock for a virtual straight line (D-D') connecting the core link shaft 243 and the first driving link shaft 241 In the direction, an angle between the core link shaft 243, the first drive link shaft 241, and the 1-1 vane link shaft 251 is formed at an acute angle.

In the state of the discharge step P2, the vane module 200 may provide an inclined wind. The inclined wind is defined as a discharge step between the horizontal wind and the vertical wind. In this embodiment, the inclined wind refers to steps P2, P3, P4, and P5.

The inclined wind discharges air below the horizontal wind in the discharge step P1. The discharge step P2 is adjusted so that both the first vane 210 and the second vane 220 face downward than in P1.

In the discharge step P2, the distance S2 between the front end 222a of the second vane 220 and the rear end 212b of the first vane 210 is the distance S1 in the state of the discharge step P1. It is formed more widely.

That is, when the discharge step P1 to P2 proceeds, the distance between the front end 222a of the second vane 220 and the rear end 212b of the first vane 210 is further increased. In the discharge step P2, the first vane 210 and the second vane 220 are disposed more vertically than P1.

When the state is changed from the discharge step P1 to the discharge step P2, the front end 222a of the second vane 220 descends, and the rear end 212b of the first vane 210 rises.

In particular, when progressing from P1 to P2, the first vane 210 further advances in the air discharge direction, and the front end 212a of the first vane rotates further in the first direction (clockwise in the drawing).

Since the second vane 220 is assembled so as to be relatively rotatable with the second vane shaft 221 and the second vane link 260, the second vane shaft is rotated by the rotation of the second vane link 220. It rotates more clockwise around (221).

The front end 222a of the second vane 220 is further rotated in the second direction (clockwise in the drawing).

When changing from the discharge step P1 to the discharge step P2, the rotation directions of the first vane 210 and the second vane 220 are opposite.

In the discharge step P2, the vane motor 230 is rotated by 78 degrees (P2 rotation angle), and the first vane 210 is inclined by approximately 16 degrees by the rotation of the vane motor 230 (the first vane P2 inclination) And the second vane 220 forms an inclination of approximately 56 degrees (the second vane P2 inclination).

Based on the discharge step P2, the third joint part 226 is further moved downward, and the first joint part 216 and the second joint part 217 are further moved forward. That is, the gap between the second vane 220 and the first vane 210 is further widened.

In the discharge step P2 state, it is similar to the discharge step P1 in which the first vane link 250, the second vane link 260 and the driving link 240 are arranged.

In the discharge step P2 state, the 1-1 vane link shaft 251 of the first vane link 250 is positioned below the 1-2 vane link shaft 252. In the discharge step P2 state, the 2-1 vane link shaft 261 of the second vane link 260 is located below the 2-2 vane link shaft portion 262. In the discharge step P2 state, the first drive link shaft 241 of the drive link 240 is positioned below the second drive link shaft 242 and the core link shaft 243.

In the state of the discharge step P2, the second vane shaft 221 is located at the uppermost side, the third joint part 226 is located below the second vane shaft 221, and the second joint part 217 is located at the third side. It is located below the joint portion 226, the first joint portion 216 is positioned below the second joint portion 217.

In the state of the discharge step P2, the second joint portion 217 is further rotated toward the 1-2th vane link shaft 252 around the core link shaft 243.

Based on the suction panel 320 or the discharge port 102, in the discharge step P2 state, the entire first vane 210 is located under the discharge port 102. In the state of the discharge step P2, the front end 222a of the second vane 220 is located below the discharge port 102, and the rear end 222b is located above the discharge port 102.

So, in the state of the discharge step P2, the first driving link shaft 241 and the first-1 vane link shaft 251 are located under the suction panel 320. In the state of the discharge step P2, the first drive link shaft 241 and the 1-1 vane link shaft 251 are located below the discharge port 102. The 2-1 vane link shaft 261 is located across the boundary of the discharge port 102.

Next, in the state of the discharge step P2, the relative positions and directions of the links are as follows.

In the discharge step P2 state, the first vane link 250 and the second vane link 260 are disposed in approximately the same direction, and the first driving link body 246 is disposed to be inclined toward the front and lower sides. In particular, in the state of the discharge step P2, the first vane link 250 and the second vane link 260 are disposed substantially vertically.

Specifically, when the state is changed from the state of the discharge step P1 to the state of the discharge step P2, L1-L1' of the first vane link 250 is slightly rotated toward the discharge direction of air. When the state of the discharge step P1 is changed to the state of the discharge step P2, L2-L2' of the second vane link 260 is slightly further rotated to the side opposite to the discharge direction of air. When the state of the discharge step P1 is changed to the state of the discharge step P2, D-D' of the first drive link body 246 is slightly rotated toward the discharge direction of air.

When changing from the discharge step P1 to the discharge step P2, the front end 212a of the first vane 210 moves to the front side more than the front edge 102a of the discharge port 102 based on the discharge port 102 do.

<Discharge step P3>

In the discharge step P2 state, the driving link 240 may be rotated in a second direction opposite to the first direction (counterclockwise in the drawing of this embodiment) to form the discharge step P3.

In the state of the discharge step P3, the vane module 200 may provide an inclined wind that is discharged further downward than the discharge step P2.

The inclined wind in the discharge step P3 discharges air downward than the inclined wind in the step P2. The discharge step P3 is adjusted so that both the first vane 210 and the second vane 220 face downward than in P2.

In the discharge step P3, the distance S3 between the front end 222a of the second vane 220 and the rear end 212b of the first vane 210 is the distance S2 in the state of the discharge step P2. More widely spaced.

That is, when proceeding from the discharge step P2 to P3, the distance between the front end 222a of the second vane 220 and the rear end 212b of the first vane 210 is further increased. In the discharge step P3, the first vane 210 and the second vane 220 are disposed more vertically than P2.

When the state is changed from the discharge step P2 to the discharge step P3, the front end 222a of the second vane 220 is further lowered, and the rear end 212b of the first vane 210 is further raised. .

In the discharge step P3 state, the front end 222a of the second vane 220 is located below the rear end 212b of the first vane 210.

When proceeding from the discharge step P2 to P3, the second vane 220 rotates in place around the second vane shaft 221, but the first vane 210 is the driving link 240 and the first vane link ( 250) and rotated (swing).

When proceeding from the discharge step P2 to P3, the first vane 210 is positioned almost in place, and is rotated in the first direction (clockwise). When proceeding from the discharge step P2 to P3, the second vane 220 is further rotated in the first direction (clockwise direction).

When proceeding from the discharge step P2 to P3, the first vane 210 rotates in the first direction (clockwise direction) in place instead of advancing in the discharge direction.

When proceeding from the discharge step P2 to P3, the front end 222a of the second vane 220 is further rotated in the first direction (clockwise direction) by the lowering of the second vane link 220.

When changing from the discharge step P2 to the discharge step P3, the rotation directions of the first vane 210 and the second vane 220 are the same.

In the discharge step P3, the vane motor 230 is rotated by 95 degrees (P3 rotation angle), and the first vane 210 is inclined by approximately 29 degrees by the rotation of the vane motor 230 (first vane P3 inclination) And the second vane 220 forms an inclination of approximately 67 degrees (the second vane P3 inclination).

In the discharge step P3, the positional relationship of the axes forming the rotation center of each link is as follows.
