When the indoor unit is stationary, the second vane 220 is positioned above the first vane 210 and above the first drive link shaft 241 and the 1-1 vane link shaft 251. The 2-1 vane link shaft 261 is located.

In addition, the 2-1 vane link shaft 261 is positioned above the second vane shaft 221, and the 2-2 vane link shaft portion 262 is disposed above the 2-1 vane link shaft 261. Is located higher.

The 2-2 vane link shaft portion 262 is positioned above the 2-1 vane link shaft portion 261 and is positioned above the core link shaft 243.

Next, in the stop step P0, the relative position and direction of each link is as follows.

Meanwhile, the first vane link 250 and the second vane link 260 are disposed in the same direction. The first vane link 250 and the second vane link 260 have an upper end located at the front side of the air discharge direction, and a lower end positioned at the rear side of the air discharge direction.

Specifically, the first 1-2 vane link shaft 252 of the first vane link 250 is located on the front side, and the 1-1 vane link shaft 251 of the first vane link 250 is located on the rear side. do. The 1-2 vane link shaft 252 of the first vane link 250 is positioned above the 1-1 vane link shaft 251. The first vane link 250 is disposed to be inclined downward to the rear based on the 1-2 vane link shaft 252.

The second vane link 260 is disposed to be inclined downward to the rear based on the 2-2 vane link shaft portion 262.

The first drive link body 246 of the drive link 240 is disposed in the same direction as the first vane link 250 and the second vane link 260, and the second drive link body 247 is the first The vane link 250 and the second vane link 260 are arranged to intersect.

<Discharge step P1>

In the stop step P0 state, the drive link 240 is rotated in a second direction (counterclockwise in the drawing of this embodiment) opposite to the first direction to provide the discharge step P1.

In the discharge step P1, the vane module 200 may provide horizontal wind.

In the horizontal wind, air discharged from the discharge port 102 may be guided by the first vane 210 and the second vane 220 to flow horizontally with the ceiling or the ground.

When the discharge air flows in a horizontal wind, the flow distance of air can be maximized.

The discharge step P1 provides a horizontal wind, and the discharged air flows along the ceiling of the room, flows downward toward the floor after hitting the wall of the room, and flows back to the indoor unit after hitting the floor. .

That is, the discharge step P1 does not provide air directly to the occupant, but provides indirect wind to the occupant.

In the discharge step P1, upper surfaces of the first vane 210 and the second vane 220 may form a continuous surface. In the discharge step P1, the first vane 210 and the second vane 220 are connected to the discharge air like one vane, and guide the discharge air.

When the vane module 200 provides an ejection step P1, which is one of a plurality of ejection steps, the first vane 210 is located under the ejection opening 102, and the front side of the second vane 220 The end 222a is positioned above the rear end 212a of the first vane 210.

The upper side of the second vane 220 is positioned higher than the upper side of the first vane 210.

In this embodiment, the first vane 210 is disposed on the front side in the flow direction of the discharge air, and the second vane 220 is disposed on the rear side in the flow direction of the discharge air. The front end 222a of the second vane 220 may be in close proximity or contact with the rear end 212b of the first vane 210. In the discharge step P1 state, the spacing S1 between the front end 222a of the second vane 220 and the rear end 212b of the first vane 210 may be minimal.

The rear end 222b of the second vane is located above the discharge port 102, and the front end 222a of the second vane is located below the discharge port 102, and the first vane The rear end 212b of the second vane is positioned lower than the front end 222a.

In the discharge step P1, the front end 222a of the second vane 220 is positioned above the rear end 212b of the first vane 210.

By approaching or contacting the front end 222a and the rear end 212b, it is possible to minimize leakage of discharge air between the first vane 210 and the second vane 220.

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

And when the vane module 200 forms a horizontal wind in the discharge step P1, since the first vane 210 and the second vane 220 are connected and operated like one vane, the airflow intensity of the horizontal wind may be increased. You can. That is, since the discharge air is guided in the horizontal direction along the top surface of the second vane 220 and the top surface of the first vane 210, the directionality of the discharge air is further enhanced as compared to forming a horizontal wind with one vane. I can do it.

When forming a horizontal wind, the second vane 220 is more inclined in the vertical direction than the first vane 210.

In the case of the horizontal wind, when viewed from the side, the first vane 210 is positioned lower than the discharge port 102, and the second vane 220 is advantageously disposed to overlap the discharge port 102. .

In the discharge step P1, the second vane 220 is rotated in place around the second vane shaft 221, but the first vane 210 is coupled with the driving link 240 and the first vane link 250. Since it is assembled, it is rotated (swing) in the direction of air discharge.

When proceeding from P0 to P1, the second vane 220 is rotated about the second vane shaft 221, the first vane 210 is lowered 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 may be moved downward through the rotation of the driving link 240 and the first vane link 250, and the first vane 210 may be disposed substantially horizontally. I can do it. Since the vane of the conventional indoor unit is a structure that is 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 drive link 240 in the second direction (counterclockwise) in the stop step P0, the second vane link 260 coupled to the drive link 240 also drives the drive link 240. It is rotated corresponding to (240).

Specifically, when changing from the stop step P0 to the discharge step P1, the drive link 240 is rotated counterclockwise, and the first vane link 210 is counterclockwise according to the rotation of the drive link 240 Rotation, and the second vane link 220 is lowered while rotating relative.

Since the second vane 220 is assembled so as to be rotatable with the second vane shaft 221 and the second vane link 260, the second vane 220 is lowered by the lowering of 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 78 degrees (P1 rotation angle), and the first vane 210 is rotated approximately 16 degrees by the rotation of the vane motor 230 (first vane P1 slope) And the second vane 220 forms a slope (second vane P1 slope) of approximately 56.3 degrees.

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 part 217 and the first joint part 216 of the first vane 210 are arranged to be inclined toward the front of the air discharge direction. When viewed from the side, the third joint portion 226 of the second vane 220 is disposed at the rearmost, the first joint portion 216 is disposed at the front, and the second joint portion 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 drive link shaft 241 is lower than the 2-1 vane link shaft 261. The 1-1 vane link shaft 251 is positioned lower than the first drive link shaft 241.

In the P1 state, the third joint part 226, the second joint part 217, and the first joint part 216 are arranged in a line, and the placement direction is directed toward the lower side of 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 lined up. Is placed.

According to an embodiment, the third joint part 226, the second joint part 217, and the first joint part 216 may not be arranged in a line.

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

In the P1 state, the first vane 210 and the second vane 220 provide a horizontal wind. The horizontal wind does not mean that the discharge direction of air is precisely horizontal. In the horizontal wind, the first vane 210 and the second vane 220 are connected as one vane, and the discharge air is horizontally connected through the connection of the first vane 210 and the second vane 220. It means the angle that makes it flow the farthest.

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

In the horizontal wind, air guided by the second vane 220 is guided to the first vane 210. Through the P1 state, when the discharge air flows in a horizontal wind, it is possible to maximize the flow distance of the air.

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

Then, in the discharge step P1, 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 P1 state, with respect to the vertical direction, the third joint portion 226 is positioned at the uppermost side, the first joint portion 216 is positioned at the lowermost side, and the second joint portion 217 is It is located in between.

In the discharge step P1, 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 drive 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.

In the discharge step P1 state, 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 positioned over the boundary of the discharge port 102.

Next, in the discharge step P1, the relative position and direction of each link are as follows.

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

In the discharge step P1, the first vane link 250, the second vane link 260, and the first drive link body 246 are arranged in the same direction. In this 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 when in the discharge step P1.

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 drive link body 246 is arranged to face the discharge direction of air.

That is, when the horizontal wind, the second vane 220 is partially located outside the discharge port 102, the entire first vane 210 is located outside the discharge port 102.

In the discharge step P1, the front side end 212a of the first vane 210 with respect to the discharge port 102 is located on the front side of the front side edge 102a of the discharge port 102.

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

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

The inclined wind discharges air downward from 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.

The discharge step P2 provides a similar wind to the horizontal wind, and the discharged air flows along the ceiling of the room, flows downward toward the floor after hitting the wall of the room, and flows back to the indoor unit after hitting the floor. Can be.

The discharge step P2 provides an indirect wind to the occupant.

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

Since the second vane 220 is assembled to be rotated relative to the second vane shaft 221 and the second vane link 260, the second vane shaft 220 is rotated by the rotation of the second vane link 220. It is rotated more clockwise around (221).

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

In the discharge step P3, the vane module 200 may provide an inclined wind discharged further downward than the discharge step P2. The discharge steps P3 to P5 are gradient winds that provide air directly to the occupants.

When cooling, the discharge air is heavier than the indoor air and flows downward, while during heating, the discharge air is lighter than the indoor air and flows upward. Therefore, the discharge step P3 is mainly used for cooling, and the discharge step P4 described later is mainly used for heating.

The inclined wind in the discharge step P3 discharges air downward from the inclined wind in the P2 step. 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 interval S3 between the front end 222a of the second vane 220 and the rear end 212b of the first vane 210 is the interval S2 in the discharge step P2 state. It is more widely spaced.

Since the length of the first drive link body 246 is shorter than the length of the first vane link 250, the upper height of the second joint portion 217 is larger.

In the discharge step P3 state, the arrangement of each axis in the drive link 240, the first vane link 250, and the second vane link 260 is similar to the discharge step P2 state.

In the discharge step P3, the second drive link body 247 is disposed toward the rear side, and the second vane link 260 is disposed toward the rear lower side.

Specifically, when changing from the discharge step P2 state to the discharge step P3 state, L1-L1 'of the first vane link 250 is slightly rotated toward the discharge direction of air. When changing from the discharge step P2 state to the discharge step P3 state, L2-L2 'of the second vane link 260 is slightly rotated to the side opposite to the air discharge direction. When changing from the discharge step P2 state to the discharge step P3 state, D-D 'of the first drive link body 246 is rotated a little further toward the air discharge direction.

In each discharge step, the slope of the second vane is always set larger than the slope of the first vane. That is, in each discharge step, the second vane is disposed vertically than the first vane.

The user may select a round swing cooling mode through a wireless remote control (not shown) or a wired remote control (not shown). (S10) In this embodiment, the round swing cooling mode is selected by the user, but unlike the present embodiment The round swing cooling mode may be automatically executed under specific conditions.

In this embodiment, when the user selects "round swing" through a wireless remote control or a wired remote control, the round swing cooling mode may be set. The cooling mode can be set according to the difference between the target temperature and the room temperature.

In the first setting step S20, the first vane module 201, the second vane module 202, the third vane module 203, and the fourth vane module 204 are all set to different discharge steps.

In the first setting step (S20), the control unit arranges the first vane module 201, the second vane module 202, the third vane module 203, and the fourth vane module 204 in an inclined order.

In this embodiment, in the first setting step (S20), the first vane module 201 among the discharge steps P2 to P5 is disposed as the slowest discharge step, and the fourth vane module 204 is disposed as the steepest discharge step. do.

So, in the first setting step (S20), the first vane module 201 discharges air at a slope of the discharge step P2 in the first discharge direction, and the first vane module 202 discharges the step P3 in the second discharge direction. The air is discharged at a slope of, the first vane module 203 discharges air at a slope of the discharge step P3 in the third discharge direction, and the first vane module 204 is a slope of the discharge step P5 in the fourth discharge direction To discharge air.

Based on the bottom view, the discharge air is discharged more vertically toward the clockwise direction.

The first setting step (S20) is operated during the first operation time. The first operating time may be a state in which each vane module is stopped in each discharge step. For example, the time when the first vane module 201 discharges air through the discharge step P2 may be set as the operation time.

Alternatively, the first operating time may be a time when each vane module is changed from each discharge step to the next discharge step. For example, the total time for the first vane module 201 to change from the previous discharge step to the corresponding discharge step may be set as the operation time.

In this embodiment, the air is discharged during the first operation time while each vane module is stopped in each discharge step.

When the step S30 is satisfied, the process proceeds to the second setting step (S40).

When the second setting step (S40) is set, the first vane module 201 is changed from the discharge step P2 to P3, the second vane module 202 is changed from the discharge step P3 to P4, and the third vane The module 203 is changed from the discharge step P4 to P5, and the fourth vane module 204 is changed from the discharge step P5 to P2.

In the first vane module, the second vane module, and the third vane module, the discharge steps are respectively increased by one step, and the slopes of the first and second vanes of each vane module are changed more steeply.

The fourth vane module 204 is returned from the discharge step P5 to P2, and the slopes of the first and second vanes are initialized from a steep state to a gentle state.

The round swing according to the present embodiment is different from that in which each vane module reciprocates within a predetermined section. In the case of a general autoswing that reciprocates a predetermined section, it proceeds to "P2->P3->P4->P5->P4->P3-P2". That is, in the conventional auto swing, the vane is slowly rotated to the lower side, and then slowly rotated again in the reverse order.

However, the round swing according to the present embodiment is rapidly returned to the initial position, such as a butterfly or a bird's wing, and then sequentially controlled from the discharge steps P2 to P5 again. Thus, the fourth vane module 204 returns to the discharge step P2 instead of being changed from the discharge step P5 to P4.

In this embodiment, the order of "P2-> P3-> P4-> P5" and then proceeding to "P2-> P3-> P4-> P5" again is defined as "circulation", and in the last discharge step of the round swing Returning to the initial discharge step is defined as "return".

When changing from the first setting step (S20) to the second setting step (S40), the fourth vane module 204 is returned from the discharge step P5 to the discharge step P2, and is initialized from a steep slope to a gentle slope.

When changing from the first setting step (S20) to the second setting step (S40), in the second setting step (S40), the remaining first vane module 201, the second vane module 202, and the third vane module ( 203) is changed to a steeper slope.

After determining that the second operation time has elapsed in step S50, the process proceeds to the third setting step (S60).

When the third setting step (S60) is set, the first vane module 201 is changed from discharge step P3 to P4, the second vane module 202 is changed from discharge step P4 to P5, and the fourth vane The module 204 is changed from the discharge step P2 to P3.

The third vane module 203 is returned from the discharge steps P5 to P2.

In the first vane module, the second vane module, and the fourth vane module, the discharge step is increased by one step, and the slopes of the first and second vanes of each vane module are changed more steeply.

The third vane module 203 is returned from the discharge step P5 to P2, and the slopes of the first and second vanes are initialized from a steep state to a gentle state.

After determining that the third operation time has elapsed in step S70, the process proceeds to a fourth setting step (S80).

When the fourth setting step (S80) is set, the first vane module 201 is changed from the discharge step P4 to P5, the third vane module 203 is changed from the discharge step P2 to the P3, and the fourth The vane module 204 is changed from the discharge steps P3 to P4.

The second vane module 202 is returned from the discharge step P5 to P2.

In the first vane module, the third vane module, and the fourth vane module, the discharge steps are respectively increased by one step, and the slopes of the first and second vanes of each vane module are changed more steeply.

The second vane module 202 is returned from the discharge step P5 to P2, and the slopes of the first and second vanes are initialized from a steep state to a gentle state.

After determining that the fourth operation time has elapsed in step S90, the process proceeds to step S100.

When proceeding to the first setting step (S20), the second setting step (S40), the third setting step (S60) and the fourth setting step (S80), the first vane module 201 is discharge step "P2-> P3 -> P4-> P5 ", the second vane module 202 proceeds to the ejection step" P3-> P4-> P5-> P2 ", and the third vane module 203 ejects the step" P4- > P5-> P2-> P3 ", and the fourth vane module 204 proceeds to" P5-> P2-> P3-> P4 ".

Thereafter, if the round swing cooling mode is not OFF, the process returns to step S20.

Steps S20 to S100 are defined as “round swing cycles”. Based on each discharge direction, the air discharged from each vane module during the "round swing cycle" is sequentially discharged from the upper side to the lower side, and is sequentially discharged from a long distance to a short distance.

When each vane module is operated in a "round swing cycle", a wind rotating around the indoor unit may be formed. As described above, the wind rotating around the indoor unit by the round swing cooling mode is defined as a round swing wind.

The round swing wind is an indirect wind that rotates around the indoor unit through sequential control of each vane module, not the wind directly discharged from each vane module. The round swing wind may be clockwise or counterclockwise based on the top view or bottom view of the indoor unit.

If the "round swing cycle" is repeated, each vane module can be operated in the same pattern as the bird's wings, and the shorter each operation time, the stronger the wings and patterns.

The round swing wind may minimize blind spots not covered by the first discharge direction, the second discharge direction, the third discharge direction, and the fourth discharge direction.

Although it is possible to provide direct wind to the user by adjusting the discharge step for each discharge direction, the number of discharge directions is limited, and a blind spot in which discharge air does not directly contact each other is inevitably created between each discharge direction.

The round swing wind can solve this blind spot by rotating the wind around the indoor unit.

When the vane module is discharge step P6, the next discharge step is returned to P1.

When each vane module circulates through six ejection steps as in this embodiment, the upper and lower angular ranges of each vane module are largely formed.

The inclination of the first vane 210 cycles between 16 degrees and 57 degrees, and the inclination of the second vane 220 cycles between 56 degrees and 74 degrees.

Hereinafter, the rest of the configuration is the same as that of the first embodiment, so detailed description is omitted.

29 is a flowchart illustrating a control method during heating according to a third embodiment of the present invention.

In the round swing heating mode, each vane module cycles through the discharge steps P3 to P6. Thus, each vane module is returned to the discharge step P3 after the discharge step P6.

Since the discharge air during the heating operation is warmer than the indoor air, the discharge step P3 perpendicular to the cooling operation is used as the initial discharge step.

In this embodiment, during the round swing heating operation, the discharge step P3 is the first discharge step, and the discharge step P6 is the last discharge step.

The first discharge step during the round swing heating operation is arranged perpendicular to the first discharge step during the round swing cooling operation. During the round swing heating operation, the last discharge step is arranged vertically than the last discharge step during the round swing cooling operation.

During the heating operation, since the discharge air has a lower density than the indoor air, it has a property of flowing upward. In the round swing heating mode, when the discharge step P2 is used as the initial discharge step as in the round swing cooling mode, the discharged air does not reach the occupants and accumulates on the upper side of the room.

To prevent this, in the round swing heating mode, a vertical discharge step is used more than the round swing cooling mode. In addition, even if the last discharge step is set as the discharge step P6, it rises upward from the discharged angle due to the characteristics of warm air, and does not flow in the form of a vertical wind during cooling operation.
