In general, an air conditioner is composed of a compressor, a condenser, an evaporator, and an expander, and supplies cooling or heated air to a room using an air conditioning cycle.

Structurally, the air conditioner is divided into a separate type in which the compressor is disposed outdoors and an integral type in which the compressor is integrally manufactured.

In the separate type, an indoor heat exchanger is installed in the indoor unit, and an outdoor heat exchanger is installed in the outdoor unit.

A compressor is installed to connect the two separate devices with a refrigerant pipe.

The integral type is an indoor heat exchanger, an outdoor heat exchanger and a compressor installed in one case. The integrated air conditioner includes a window type air conditioner which is installed directly by hanging the device on a window, and a duct type air conditioner which is installed outside the room by connecting an intake duct and a discharge duct.

At this time, since the position of the 2-1 vane shaft 352 of the second vane 350 is fixed to the link installation unit 110, the driving link 310 rotates while the second driving link body 318 is rotated. and the second vane 350 may contact each other, thereby limiting rotation. In order to prevent such interference, the 2-2nd vane link shaft 333 and the 2-1th vane shaft 352 may be disposed to be spaced apart from each other by a predetermined distance or more. The gap is preferably positioned so that the 2-2nd vane link shaft 333 and the 2-1 vane shaft 352 have the shortest distance so that the 2-2nd vane link shaft 333 and It may be defined as an interval between the second-first vane shafts 352 .

In addition, referring to FIG. 8 , the second vane link 330 may have a curved shape so that contact or interference with the second vane 350 does not occur while the driving link 310 rotates.

2 and 4 , the first vane 340 rotates, and the discharge port 101 may be opened or closed depending on the rotation direction. At this time, a direction in which the first vane 340 allowing the discharge port 101 to be opened is defined as a first rotation direction R1 . The first rotation direction R1 is counterclockwise when referring to FIG. 4 .

When the first vane 340 rotates in the first rotation direction R1 , at least a portion of the first vane 340 approaches the connection part 316 of the first driving link body 313 .

The first vane 340, referring to FIG. 9, based on the discharge flow direction of the air, the side from which the discharge air moves away from the vane is the first vane front end 345, and the side through which the discharge air approaches the vane is It is the rear end 346 of the first vane. When the first vane 340 rotates in the first rotational direction R1 , the rear end of the first vane 340 may come closer to the connecting portion 316 of the first driving link body 313 .

The rotation shaft disposed at the other end of the second member 315 may coincide with the first-first vane shaft 342 of the first vane 340 . The axis disposed on the core body 311 and the center of the core body shaft 312 may coincide with each other. The rotation shaft disposed at the other end of the second member 315 forms a straight line with the core body shaft 312 . When the first vane 340 rotates in the first rotation direction R1 , the rear end of the first vane 340 may pass through the straight line and approach the connection part 316 .

When the first vane 340 rotates in the first rotational direction R1 , the rear end of the first vane 340 may contact the connection part 316 . At this time, the first vane 340 no longer rotates in the first rotation direction R1 any longer. Accordingly, the connection part 316 serves as a stopper limiting the maximum rotation range of the first vane 340 .

In addition, the first driving link body 313 may have a curved shape or a bent shape. At this time, the connecting portion 316 of the first driving link body 313 is formed at a position in contact with the rear end of the first vane 340 when the first vane 340 rotates in the maximum rotation range.

Also, when the discharge port 101 is opened, the first vane 340 rotates in the first rotational direction R1 , and the driving link 310 rotates in the second rotational direction R2 . The second rotation direction R2 may be opposite to the first rotation direction R1. The second member 315 of the first driving link body 313 may be formed to extend from the connecting portion 316 in a direction opposite to the second rotational direction R2.

Meanwhile, the rotation range of the first vane 340 is based on the angle of the first vane 340 when the indoor unit is stopped and the first vane 340 closes the discharge port 101 . . At this time, the maximum rotation angle Amax of the first vane 340 may be 150°, preferably 140°. In this case, the maximum rotation angle Amax of the first vane 340 is the second This is an angle formed in a state in which the rear end of the first vane 340 is placed in contact with the connecting portion 316 of the driving link 310 to prevent further rotation in the first rotational direction R1. The maximum rotation angle Amax is a distance between both axes 322 and 323 of the first vane link 320, a distance between both axes 342 and 343 of the first vane rib 344, and a core body axis 312. It may vary depending on the distance between the and the first driving link shaft 317 . In addition, the maximum rotation angle Amax may vary according to a bending angle AL between the first member 314 and the second member 315 . For example, the distance between both axes 322 and 323 of the first vane link 320, the distance between both axes 342 and 343 of the first vane rib 344, and the core body shaft 312 and the first drive Assuming that the distances between the link shafts 317 are the same, the rear end of the first vane 340 is driven as the included angle AL between the first member 314 and the second member 315 is smaller. The link 310 may be further inserted into the connection portion 316 side, and in this case, the maximum rotation angle Amax may be further increased.

1 and 9 , the vane module 300 may include a first vane 340 disposed on the outlet 101 side.

The first vane 340 is a component that is disposed at the discharge port 101 and guides the discharged air. The first vane 340 may be relatively rotatably connected to the first driving link body 313 , and may be relatively rotatably connected to the other end of the first vane link body 321 .

In the present embodiment, the first vane 340 may include a first vane body 341 , and the first vane body 341 may be formed to extend long in the longitudinal direction of the discharge port 101 .

Referring to FIG. 9 , the direction of the first vane 340 is defined. Based on the flow direction of the discharged air, the side through which the air is discharged by receiving the guidance of the first vane 340 is the front. The side through which the air before being guided by the first vane 340 is introduced is the rear. Based on the horizontal discharge mode, the surface that guides the air flowing through the upper portion of the first vane 340 is referred to as the upper surface.

A first-first vane shaft 342 connected to the first drive link shaft 317 of the first drive link body 313 so as to be relatively rotatable is formed on the first vane rib 344 . When the first driving link body 313 is connected to the first vane 340 , the first driving link shaft 317 and the 1-1 vane shaft 342 overlap.

The first vane rib 344 is formed with a first-second vane shaft 343 connected to the first-first vane link shaft 322 of the first vane link body 321 to be relatively rotatable. When the first vane rib 344 is connected to the first vane link 3240, the 1-1 vane link shaft 322 is closer to the link installation unit 110 than the 1-2 vane shaft 343 and may be disposed, and may also be overlapped with each other. Overlapping.

In addition, in the first vane rib 344 , the 1-1 vane shaft 342 is the rear end side of the first vane 340 , and the 1-2 vane shaft 343 is the first vane 340 . It may be disposed close to the front end. In other words, the 1-1 vane shaft 342 is disposed behind the 1-2 vane shaft 343 . In other words, the connection point of the driving link 310 and the first vane 340 is disposed behind the connection point of the first vane link 320 and the first vane 340 . As the two shafts 342 and 343 formed on the first vane rib 344 are disposed to be spaced apart, when the driving link 310 rotates in the second rotation direction R2, the first vane 340 is It rotates in one rotational direction R1, and at the same time, the first vane 340 moves to the rear of the discharge port. Conversely, when the driving link 310 rotates in the opposite direction to the second rotational direction R2, the first vane 340 rotates in the opposite direction to the first rotational direction R1, and at the same time, the first vane 340 rotates in the opposite direction to the first rotational direction R1. It moves to the front of the discharge port.

In addition, based on the longitudinal direction of the second member 315, the distance between one end of the second member 315 and the 1-1 vane shaft 342 is the 1-1 vane shaft 342 and It may be shorter than the shortest distance between the first and second vane shafts 343 . Specifically, among the points at which a tangent line of inclination perpendicular to the longitudinal direction of the second member 315 is formed in the first driving link body 313 , the first from a point further away from the 1-1 vane shaft 342 . The distance from the center of the -1 vane shaft 342 may be shorter than the shortest distance between the center of the 1-1 vane shaft 342 and the 1-2 vane shaft 343 .

In this case, in the closing step of the first vane 340 , the first vane 340 rotates in a direction opposite to the first rotational direction R1 , and the driving link 310 rotates in the opposite direction to the second rotational direction R2 . At this time, a part of the first driving link body 313 moves into the space between the 1-1 vane shaft 342 and the 1-2 vane shaft 343 of the first vane rib 344 and , because interference occurs between the first vane 340 and the driving link 310 in the process, so that the rotation range of the first vane 340 may be limited.

The distance between the connection part 316 and the first driving link shaft 317 may be shorter than the distance between the 1-1 vane shaft 342 and the 1-2 vane shaft 343 . Accordingly, when the first vane 340 rotates in the second rotation direction to shield the discharge port 101 , the second member is disposed between the 1-1 vane shaft 342 and the 1-2 vane shaft 343 . are placed

9 and 11 , the first vane 340 is disposed at the discharge port 101 and is formed in a plate shape.

The upper surface of the first vane 340 is a surface disposed on the inner side of the air inflow direction when the first vane 340 shields the discharge port. The lower surface of the first vane 340 is a surface disposed on the outside air discharge direction when the first vane 340 shields the discharge port. The front surface of the first vane 340 is a surface disposed on the upper end of the outlet when the first vane 340 shields the outlet. The rear surface of the first vane 340 first contacts the discharge air among the first vanes 340 . The rear surface of the first vane 340 is a surface disposed at the lower end of the discharge port when shielding the discharge port of the first vane 340 . The rear surface of the first vane 340 faces the front surface. The first vane 340 has a left surface disposed at the left end of the discharge port. The first vane 340 has a right side opposite to the left side. The right side of the first vane 340 is disposed at the right end of the discharge port.

In other words, the discharge port is formed to be elongated left and right, and the first vane 340 is formed in a plate shape elongated from side to side.

Referring to FIG. 11 , the first vane 340 includes a curvature C (Curvature) on the upper surface or the lower surface. The first vane 340 may include a double curvature on the upper surface or the lower surface.

Referring to FIG. 11 , the first vane 340 includes first and second curvatures c1 and c2 on the upper surface or the lower surface in the longitudinal direction of the outlet 101 . The first and second curvatures c1 and c2 are formed to be elongated in the longitudinal direction of the discharge port 101 . The first vane 340 includes first and second curvatures c1 and c2 , and both side ends of the first vane 340 and the center of the first vane 340 have different heights.

When the air conditioner is operating, the first vane 340 does not block the discharge port 101 , and both side ends of the first vane 340 and the center of the first vane 340 have different heights and are disposed and discharged. guide the air

When the air conditioner is stopped, the first vane 340 shields the discharge port 101, and the center of the first vane 340 droops downward by its own weight. When the restoring force due to the deformation of the first vane having the first and second curvatures c1 and c2 matches the load due to its own weight, the first vane 340 becomes a flat plate to closely shield the outlet 101 .

The first vane 340 includes a third curvature c3 on the upper surface or the lower surface in a direction intersecting the first and second curvatures c1 and c2. The first vane 340 may include the first and second curvatures c1 and c2 and the third curvature c3 double.

12 provides a left sectional view for each position of the first vane 340 . 12A is a cross-sectional view taken from A-A' on the left, in which the central portion 349 is shown above the cross-section. 12B is a cross-sectional view taken from B-B' to the left, showing a central portion 349 and a right side 348 below the central portion. 12C is a cross-sectional view taken from C-C' to the left, with a right side 348 shown below the cross-section.

Preferably, referring to FIG. 11 , the upper surface of the first vane 340 has a first curvature c1 so as to be upwardly convex. In this case, the first center of curvature e1 is disposed below the first vane 340 .

The first curvature c1 is concavely formed in the air discharging direction based on when the first vane 340 shields the discharge port 101 . When the first vane 340 shields the discharge port 101, the air discharge direction corresponds to the lower surface of the first vane 340, and the first curvature c1 has a first curvature c1 so that the lower surface is concave. ) can be formed.

The first curvature c1 has an upper surface convex upward.

The first vane 340 is supported at both side ends 347 and 348, and the central portion 349 of the first vane droops downward by its own weight. Therefore, when the first vane 340 shields the discharge port 101, the central portion 349 of the first vane sags downward, and thus, the center of the discharge port 101 is not tightly shielded.

On the other hand, when the third vane link 360 guiding the rotation of the first vane 340 is disposed inside the first vane 340, when the first vane 340 rises, the third vane link ( 360) causes resistance. Accordingly, when the first vane 340 moves, slip occurs in the central portion 349 of the first vane. As a result, when the first vane 340 shields the outlet 101, the slip phenomenon causes a problem in that the center of the outlet 101 is not tightly shielded.

Therefore, when the first vane 340 shields the discharge port, there is a problem that the central portion is not tightly shielded due to sagging due to the weight of the first vane 340 or a slip phenomenon due to the third vane link 360 . . According to the present invention, the first and second curvatures c1 and c2 are formed so that the upper surface is convex upward, so that the first vane 340 sags due to its own weight or the slip phenomenon occurs due to the third vane link 360 .

In addition, the front end of the central portion 349 of the first vane 340 may deviate forward by about 3.5 mm in the tangential direction from the rear end of the side end of the first vane 340, and is disposed to deviate upward by about 3.4 mm in the normal direction. can be

Referring to FIG. 14 , the first radius of curvature d1 is shorter than the second radius of curvature d2 , and the front end of the first vane 340 has a sharper curvature than the rear end of the first vane 340 . The third vane link 360 is disposed at the rear end of the first vane 340 , and when slip occurs in the third vane link 360 , the first vane 340 rather than the rear end of the first vane 340 . The difference is more pronounced at the shear of the Therefore, when the first radius of curvature c1 is formed shorter than the second radius of curvature c2, when slip occurs in the third vane link 360, the front and rear ends of the first vane 340 have a uniform width. Slip as much to make it flat.

The center of curvature e1 of the first curvature c1 may coincide with the center of curvature e2 of the second curvature c2.

Preferably, referring to FIG. 13 , the upper surface of the first vane 340 has a third curvature c3 to be upwardly convex. In this case, the third center of curvature e3 is disposed above the first vane 340 .

The third curvature c3 may be formed in a direction perpendicular to the direction of the first curvature c1 . In other words, the third curvature c3 is formed perpendicular to the longitudinal direction of the discharge port 101 .

The third curvature c3 is formed to be convex in the air discharge direction when the first vane 340 shields the discharge port 101 . When the first vane 340 shields the discharge port 101 , the air discharge direction refers to the lower side of the first vane 340 . In other words, the third curvature c3 is convex downward.

The center of curvature e3 of the third curvature c3 is disposed on the opposite side of the center of curvature e1 of the first curvature with respect to the first vane 340 . That is, referring to FIG. 13 , the center of curvature e1 of the first curvature is located below the first vane 340 , and the center of curvature e3 of the third curvature is located above the first vane 340 . .

The first curvature c1 and the third curvature c3 are formed in a direction crossing each other, and thus have a strong effect on external impact and deformation.

The first curvature c1 and the third curvature c3 have the center of curvature disposed in opposite directions with respect to the first vane 340 , and thus have a strong effect on impact and deformation.

The first vane link 320 is a component for guiding the movement of the first vane 340 . The first vane link 320 guides the movement of the first vane 340 together with the driving link 310 .

1 and 2 , one end of the first vane link 320 is connected to the case 100 , and the other end is connected to the first vane 340 . The first vane link 320 rotates with the connection point to the case 100 as a rotation axis. A connection point between the first vane link 320 and the case 100 is defined as a 1-2 vane link shaft 323 . The first vane 340 may move along a virtual circular trajectory centering on the 1-2 vane link shaft 323 .

The first vane link 320 includes a first vane link body 321 . The first vane link body 321 forms the outer shape of the first vane link 320 .

The first vane link body 321 may be formed to be curved. The first vane link body 321 may include a convex bent portion in the opposite direction of the driving link 310 . Accordingly, the driving link 310 maintains a spaced apart state from the first vane link body 321 when rotating.

The first vane link 320 includes a 1-2 vane link shaft 323 . The 1-2 vane link shaft 323 is disposed at one end of the first vane link body 321 . The 1-2 vane link shaft 323 coincides with the connection point between the first vane link 320 and the case 100 .

The first vane link 320 includes a 1-1 vane link shaft 322 . The 1-1 vane link shaft 322 is disposed at the other end of the first vane link body 321 . The 1-1 vane link shaft 322 coincides with the connection point between the first vane link 320 and the first vane 340 . That is, when the first vane link 320 and the first vane 340 are connected, the 1-1 vane link shaft 322 and the 1-2 vane shaft 343 overlap.

The first vane link 320 is disposed in front of the driving link 310 . When the driving link 310 rotates in one direction, the first vane link 320 guides the first vane 340 forward while rotating.

The third vane link 360 is disposed between the first vane link 320 fastened to the left end of the first vane 340 and the first vane link 320 fastened to the right end of the first vane 340 . do. The third vane link 360 may be symmetrically disposed. The third vane link 360 is disposed on the inside of the first vane link 320 to prevent sagging due to the weight of the central portion 349 of the first vane 340 .

However, the third vane link 360 may generate a slip when the first vane 340 rotates. For example, when a frictional force exists at the connection point between the third vane link 360 and the case, the third vane link 360 may act as a resistance when the first vane 340 rotates, and the first vane 340 Slip may occur during rotation.

The connection point of the third vane link 360 and the first vane 340 is disposed above the connection point of the first vane link 320 and the first vane 340 . 13, the connection point of the third vane link 360 and the first vane 340 is disposed to be spaced apart from the connection point of the first vane link 320 and the first vane 340, and the axis of rotation is different to This is to stably support the first vane 340 from vibration. Further, the central portion 349 of the first vane 340 protrudes upward by a predetermined distance by the first curvature c1, and the connection point between the third vane link 360 and the first vane 340 is the first It is disposed above the connection point of the vane link 320 and the first vane 340, and is stably supported when the first vane 340 rotates.

Referring to FIG. 13 , the connection point of the first vane 340 and the first vane link 320 is disposed to be spaced apart from the connection point of the first vane 340 and the first driving link body 313 . The connection point of the first vane 340 and the first vane link 320 is disposed at the rear end of the first vane 340 . The connection point of the first vane 340 and the first driving link body 313 is disposed in front of the connection point of the first vane 340 and the first vane link 320 . Since the connection point of the first vane 340 and the first vane link 320 is spaced apart from the connection point of the first vane 340 and the first driving link body 313, when the driving link 310 rotates, the first The vane 340 is also capable of translational motion along with rotational motion. However, when the translational motion occurs, the third vane link 360 cannot effectively guide the rotational motion of the first vane 340 because a slip phenomenon occurs. Accordingly, slip of the first vane 340 is prevented by forming the first curvature c1 or the second curvature c2 on the first vane 340 .

Referring to FIG. 13 , a virtual first straight line L1 connecting the front end and the rear end of the left or right side of the first vane 340 is a virtual second connecting the front end and the rear end of the central portion of the first vane 340 .

Referring to FIG. 13 , a virtual first straight line L1 connecting the front end and the rear end of the left end 347 of the first vane 340 is a virtual first line L1 connecting the front end and the rear end of the central portion of the first vane 340 . Two straight lines L2 intersect with each other. In more detail, the first straight line L1 and the second straight line L2 intersect each other at the rear of the first vane 340 . In other words, with respect to the intersection point e4 , the inclination of the second straight line L2 is steeper than the inclination of the first straight line L1 . The third vane link 360 is disposed in the second half of the first vane 340 when viewed from the side. Therefore, when slip occurs in the third vane link 360 , a difference occurs significantly at the front end than at the rear end of the first vane 340 . When the slip occurs, the front of the second straight line L2 is more deformed than the rear, and the second straight line L2 moves in a direction overlapping the first straight line L1 . Accordingly, even when slip occurs, the first vane 340 may tightly shield the discharge port.

The distance between one end and the other end of the third vane link 360 may be formed shorter than the distance between the one end and the other end of the first vane link 320 .
