<Explanation of the operation of the discharge vane>

An operation of the discharge vane will be described in more detail with reference to FIGS. 4 to 7 .

When the vane motor 220 rotates the driving link 320 clockwise to the maximum, the discharge vane 200 forms a state as shown in FIG. 4 . In the present embodiment, the state of FIG. 4 is a state when the indoor unit is not operated.

When the driving link 320 is rotated counterclockwise in the state of FIG. 4 , the discharge vane 200 maintains the state as shown in FIG. 5 . In this embodiment, the state of FIG. 5 is a state when horizontal wind is provided.

When the driving link 320 is further rotated counterclockwise in the state of FIG. 5 , the discharge vane 200 maintains the state as shown in FIG. 6 . In the present embodiment, the state of FIG. 6 is a state when the inclined wind is provided.

And when the driving link 320 is rotated counterclockwise in the state of FIG. 6 , the discharge vane 200 maintains the state as shown in FIG. 7 . When the vane motor 220 rotates the driving link 320 counterclockwise to the maximum, the driving link 320 forms a state as shown in FIG. 7 . In this embodiment, the state of FIG. 7 is a state when vertical wind is provided.

The first vane 210 and the second vane 240 contact, overlap, or close to form a horizontal wind guide surface 201, and discharge air through the horizontal wind guide surface 201 to the ground, ceiling, case bottom or Horizontal wind is defined as the state of discharging generally parallel or horizontal to the bottom of the cover panel. In the case of the horizontal wind, the discharge air flowing through the horizontal wind guide surface 201 generally flows in parallel to the ground, the ceiling, the bottom surface of the case or the bottom surface of the cover panel.

The horizontal wind is discharged substantially parallel to the ground, the ceiling, the bottom of the case or the bottom of the cover panel in order to flow to the furthest part of the room instead of directly supplying the discharged air to the user. The discharge air discharged as a horizontal wind may not flow accurately in the horizontal direction because a vortex may be generated during the flow process. Therefore, in this embodiment, the term "generally horizontal" or "generally parallel" is used, and the intention of the horizontal wind is to discharge air in the horizontal direction to flow the air to a far place in the room. . When providing the horizontal wind, the discharge air is guided through the horizontal wind guide surface 201 formed by the first vane 210 and the second vane 240 .

The entire horizontal wind guide surface 201 need not be horizontally disposed. In this embodiment, the rear side of the horizontal wind guide surface 201 is inclined and the front side is generally horizontally arranged.

And, as shown in FIG. 6, most of the discharged air is guided through at least one of the upper or lower surfaces of the first vane 210 and the second vane 240, and the front end of the first vane 210 is The state in which it is inclinedly arranged toward the lower side is defined as an inclined wind. In the case of an inclined wind, the second vane 240 is generally vertically disposed.

In the case of an inclined wind, the discharge air guided through the upper surface of the second vane 240 may be directed toward the lower surface of the first vane 210 . In the case of the inclined wind, the second vane 240 may be disposed parallel to the first vane 210 .

When forming the inclined wind in this embodiment, the first vane 210 and the second vane 240 are spaced apart from each other, and the second vane 240 is disposed more vertically than the first vane 210 . do.

And a state in which the first vane 210 and the second vane 240 are installed generally vertically toward the ground is defined as a vertical wind. In the case of vertical wind, the discharge air is guided vertically toward the ground by striking the lower surface of the first vane 210 . In the case of vertical wind, the discharge air is generally vertically guided through the upper and lower surfaces of the second vane 240 .

When the vertical wind is provided, the first vane 210 is in close contact with the front side of the outlet 102 , and the second vane 240 is in close contact with the rear side of the outlet 102 .

When the horizontal wind, the inclined wind or the vertical wind is provided, at least a portion of the first vane 210 may be lowered to the lower side of the outlet 102 to be located below the outlet 102 .

When providing a horizontal wind, an inclined wind, or a vertical wind, at least a portion of the second vane 240 may be located in the outlet 102 .

Hereinafter, the operation process of the discharge vane will be described in more detail.

In the state of FIG. 4 , the indoor unit or the discharge vane 200 may be in an inoperative state or in a state in which air is not discharged.

In the state of FIG. 4 , the second vane 240 is positioned above the first vane 210 . When viewed in a plan view, the second vane 240 is positioned between the plurality of coupling flanges 214 , and positioned above the first vane body 212 .

The first vane 210 is rotated while being restrained by the first guide link 310 and the driving link 320 , and is located in the outlet 102 . A lower surface of the first vane 210 forms a continuous surface with the cover panel 120 .

And a first guide link 310, a driving link 320 and a second guide link 360 necessary for rotating the first vane 210 and the second vane 240 on the upper side of the first vane 210 are is positioned, and the first guide link 310 , the driving link 320 , and the second guide link 360 are not visible from the outside by the first vane 210 . That is, the first vane 210 is positioned below the first guide link 310 , the driving link 320 , and the second guide link 360 , and the first guide link 310 , the driving link 320 . ) and the second guide link 360 is hidden.

When the indoor unit is not operated, since the second vane 240 is located above the first vane 210, it is in a hidden state when viewed from the outside. The second vane 240 is exposed to the user only when the indoor unit is operated. Therefore, the second vane 240 is positioned on the discharge passage 104 when the indoor unit is not in operation, and the first vane 210 covers most of the discharge port 102 .

In the present embodiment, the first vane 210 covers only most of the outlet 210 , but the first vane 210 may be formed to cover the entire outlet 210 according to design.

In the state of FIG. 4 , the first vane 210 is accommodated in the outlet 102 , and when the first vane 210 is accommodated in the outlet 102 , the first vane 210 is The same plane as the bottom surface of the cover panel 120 may be formed. That is, when the discharge vane 200 is not operated, the lower surface of the first vane 210 does not protrude to the outside of the cover panel 120 and forms a continuous surface with the cover panel 120 . .

5, the discharge vane 200 may form a horizontal wind. When the discharge air flows in a horizontal wind, the flow distance of the air can be maximized.

When forming the horizontal wind, the first vane 210 and the second vane 240 are connected to form a horizontal wind guide surface 201 that operates like a single vane. In this embodiment, the second vane 240 is located on the rear side of the first vane 210 , and the front end 242a of the second vane 240 is on the rear side of the first bay 210 . It may be close to or in contact with the end 212a.

By bringing the front end 242a and the rear end 212a into proximity or contact, when forming a horizontal wind, it is possible to suppress the leakage of the discharge air between the first vane 210 and the second vane 240. can

In this embodiment, the front end 242a and the rear end 212a are brought into close contact with each other, but are not brought into contact. Instead, in order to prevent the discharge air from leaking between the first vane 210 and the second vane 240 , the front end 242a of the second vane 240 is placed on the upper side of the first vane 210 . When positioned and viewed in a plan view, the front side of the second vane 240 overlaps the first vane 210 . In this case, the air guided along the upper surface of the second vane 240 may be guided to the upper surface of the first vane 210 , and air resistance and leakage may be minimized.

Also, when forming a horizontal wind, at least a portion of the first vane 210 and the second vane 240 overlap, and the front end 242a of the second vane is the rear end 212a of the first vane. Since it can be supported on the , it is possible to suppress the vibration generated when the discharge air collides with the first vane 210 and the second vane 240 .

And when forming a horizontal wind, since the first vane 210 and the second vane 240 are connected to operate as one vane, the airflow intensity of the horizontal wind can be increased. That is, since the discharge air is guided in the horizontal direction along the upper surface of the second vane 240 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. can do it

When forming a horizontal wind, the second vane 240 is more inclined in the vertical direction than the first vane 210 .

In the case of providing the horizontal wind, when viewed from the side, the first vane 210 is positioned below the outlet 102 , and the second vane 240 is disposed to overlap the outlet 102 . it is advantageous

When the first vane 210 is rotated at the same height as in FIG. 4 , the amount of air guided to the first vane 210 is reduced due to interference with the discharge air.

As shown in FIG. 5 of this embodiment, after the first vane 210 descends to the lower side of the discharge port 102, most of the discharge air can be guided in the horizontal direction only when aligned in a substantially horizontal direction.

In this embodiment, the first vane 210 can be moved to the lower side of the outlet 102 through the rotation of the first guide link 310 and the driving link 320, and the direction of the first vane 210 is also horizontal. can form Since the vane of the conventional indoor unit has a structure that rotates in place, the same effect as the present embodiment cannot be realized.

In the state of FIG. 4 , the vane motor 220 rotates the driving link 320 counterclockwise to form the state of FIG. 5 . The driving link 320 is rotated about the driving shaft 323 .

In the state of Figure 4, when the driving link 320 is rotated counterclockwise, the first guide link 310 is rotated counterclockwise about the second guide link shaft 312, through which the The first vane 210 is rotated counterclockwise while descending to the lower side while covering the outlet 102 .

According to the counterclockwise rotation of the driving link 320, relative rotation is also generated in the first guide link coupling part 361 and the second guide link coupling part 362 of the connecting link 360, respectively, and the second The vane 240 is rotated clockwise about the second vane shaft 241 .

Since the first vane 210 is rotated in the state configured by the driving link 320 and the first guide link 310, it is operated in the form of swing, not rotation.

When changing from the state of Fig. 4 to the state of Fig. 5, the first vane 210 not only descends from the upper side to the lower side, but also the entire first vane 210 rotates counterclockwise while the first vane 210 The front end (212b) of the is rotated clockwise.

In order to form the horizontal wind, when the state of FIG. 4 is changed to the state of FIG. 5 , the rotation directions of the first vane 210 and the second vane 240 are reversed.

In the state of FIG. 5 , when air is discharged in the horizontal wind, it is advantageous for the first vane 210 to be positioned below the discharge port 102 to form the air volume of the horizontal wind.

When the horizontal wind is provided in the state of FIG. 5 , the first guide link 310 is positioned in front of the driving link 320 with respect to the driving link 320 , and the second guide link 360 . is located at the rear of the driving link 320 .

When the horizontal wind is provided, the first vane 210 is positioned below the discharge port 102 , and through this, a larger amount of the discharge air can be provided as a horizontal wind.

When the first vane 210 is disposed generally horizontally to form the air discharged from the outlet 102 in a horizontal wind, the first vane 210 is the lower surface of the case 100 (this embodiment). is spaced apart from the bottom surface of the cover panel 120 by a predetermined distance, and is located further below the bottom surface of the cover panel 120 .

Since the first vane 210 is supported by the first guide link 310 and the driving link 320 in the state of FIG. 5 to form a horizontal wind, the air discharged from the outlet 102 is the first Vibration generated by colliding with the vane 210 can be suppressed.

When the front end 242a of the second vane 240 and the rear end 212a of the first vane 210 come into proximity or contact, the motor shaft 221 is stopped.

In this embodiment, in order to prevent the discharge air from leaking between the first vane 210 and the second vane 240, the front end 242a of the second vane 240 is removed from the first vane 210. placed on top of

When viewed from the top view, the front side of the second vane 240 overlaps the first vane 210 . Since the front side of the second vane 240 is overlapped with the rear side of the first vane 210 , the discharge air flowing along the discharge passage 104 is transferred to the front end 242a of the second vane 240 . ) and it can suppress the flow between the rear end (212a) of the first vane (210).

When the horizontal wind guide surface 201 is disposed generally horizontally to form the air discharged from the discharge port 102 as a horizontal wind, the first vane 210 is the bottom surface of the case 100 (this embodiment). is spaced apart from the bottom surface of the cover panel 120 by a predetermined distance, and is located further below the bottom surface of the cover panel 120 .

When providing a horizontal wind, it is advantageous to arrange the front end of the horizontal wind guide surface 201 substantially horizontally.

Since the first vane 210 is supported by the first guide link 310 and the driving link 320 in the state of FIG. 5 to form a horizontal wind, the air discharged from the outlet 102 is the first Vibration generated by colliding with the vane 210 can be suppressed.

Since the second vane 240 is supported by the second guide link 360 and the second vane shaft 241 in the state of FIG. 5 to form a horizontal wind, the air discharged from the outlet 102 is It is possible to suppress the vibration generated by colliding with the two vanes 240 .

When the driving link 320 is further rotated counterclockwise through the vane motor 220 in the state of FIG. 5 , the state shown in FIG. 6 may be formed.

When the state of FIG. 5 is changed to the state of FIG. 6 , the front end 212b of the first vane 210 is rotated clockwise, and the first vane 210 is further rotated counterclockwise.

Based on the first vane coupling portion 216 of the first vane 210, the first vane 210 is rotated clockwise as a whole.

When the state of FIG. 5 is changed to the state of FIG. 6 , the second vane 240 is rotated clockwise.

That is, when the driving link 320 is further rotated counterclockwise in the state of FIG. 5 forming a horizontal wind, both the first vane 210 and the second vane 240 may rotate in the same clockwise direction.

In the state of FIG. 6 , both the first vane 210 and the second vane 240 are disposed to be inclined with respect to the vertical direction. In the present embodiment, the first vane 210 and the second vane 240 are arranged to be inclined with respect to the vertical direction, and the inclination angles are different.

When providing the inclined wind in this embodiment, the second vane 240 may be disposed more vertically than the first vane 210 .

In this way, when the first vane 210 is disposed more gently and the second vane 240 is disposed more vertically, the flow angle of the discharge air may be increased.

When the inclined wind is provided, the rear end 212a of the first vane 210 and the front end 242a of the second vane are spaced apart.

When the driving link 320 is further rotated counterclockwise in the state of FIG. 6 , the state shown in FIG. 7 may be formed.

7, the discharge vane 200 may form a vertical wind. When the first vane 210 and the second vane 240 form a vertical wind, the vane intersects or is perpendicular to the ceiling or the ground, and is disposed in the vertical direction.

In this embodiment, the vertical wind is formed when the first guide link 310 is rotated to the maximum in the counterclockwise direction. In this state, the first vane 210 is disposed substantially perpendicular to the ceiling or the ground, and is in close contact with the inner front of the outlet 102 .

When a portion of the first vane 210 is not in close contact with or inserted into the discharge port 102 , some air may be discharged in a direction other than the vertical wind.

When the first vane 210 is disposed in the vertical wind, the discharge air is guided to the ground through the bottom surface of the first vane 210 . The upper surface of the first vane 210 is preferably in close contact with the cover panel 120 side as much as possible to minimize the flow of the discharge air.

In this embodiment, the vertical wind is formed when the driving link 320 is rotated to the maximum counterclockwise. In this state, the driving link 320 is located at the front end 332b of the guide slot 332 .

When changing from FIG. 6 to FIG. 7 , the second vane 240 is rotated clockwise about the second vane shaft 241 .

In the state of FIG. 7 providing vertical wind, the first vane 210 is in close contact with the front side of the outlet 102, and the second vane 240 is in close contact with the rear side of the outlet 102, so the air discharged from the outlet is Almost all of them move downwards.

When the vertical wind is provided in the state of FIG. 7 , most of the discharged air flows between the lower side of the first vane 210 and the upper side of the second vane 240 , and is generally discharged in a vertical direction.

In order to provide a vertical wind, when the driving link 320 is rotated, the first guide link coupling part 361, the second guide link coupling part 362 and the driving shaft 323 may be arranged in a line. Preferably, the angle between the first guide link coupling part 361, the second guide link coupling part 362 and the driving shaft 323 is formed to be less than 180 degrees.

When the second guide link coupling part 362 is located on the more front side than the imaginary straight line S connecting the first guide link coupling part 361 and the driving shaft 323, the second guide link ( 360) cannot be returned to its original position. So, when the driving link 320 is rotated counterclockwise, the second guide link coupling part 362 is more than the imaginary straight line S connecting the first guide link coupling part 361 and the driving shaft 323. It is preferable to adjust the rotation angle of the motor shaft 221 so as to be located on the rear side.
