The fastening member 401 provided to fix the module
body portion 402 is in the state of being fastened from the
lower side to the upper side, and may be separated from the
upper side to the lower side.
D A fastening hole 403, through which the fastening
member 401 is inserted, is formed in the module body portion
402.
In the case in which it is necessary to distinguish
between the fastening hole formed in the first module body
410 and the fastening hole formed in the second module body
420 for convenience of description, the fastening hole
formed in the first module body 410 is referred to as a
first fastening hole 403-1, and the fastening hole formed in
the second module body 420 is referred to as a second
fastening hole 403-1.
Also, in the case in which it is necessary to
distinguish between the fastening members 401, the fastening
member 401 installed in the first fastening hole 403-1 is
defined as a first fastening member 401-1, and the fastening
member 401 installed in the second fastening hole 403-1 is
88264224.1 defined as a second fastening member 401-2.
The first fastening member 401-1 is fastened to the
front body 310 through the first fastening hole. The second
fastening member 401-2 is fastened to the front body 310
through the second fastening hole.
Before fixing the module body 400 by fastening, a
module hook 405 configured to temporarily fix the position
of the module body 400 is disposed.
The module hook 405 is coupled to the front panel 300,
D specifically the front body 310. Specifically, the module
hook 405 and the front body 310 are caught by each other.

fastening holes 403 are disposed in a line.
Even when the fastening members 401 are removed, the
state in which the vane module 200 is coupled to the frame
body 310 may be maintained by the module hooks 405.
When it is necessary to separate the vane module at
the time of repair or trouble, the state in which the vane
module 200 is coupled to the frame panel 300 is maintained
even when the fastening member 401 is removed. As a result,
a worker does not need to separately support the vane module
200 at the time of removing the fastening member 401.
Since the vane module 200 is primarily fixed by the
module hook 405 and is secondary fixed by the fastening
member 401, it is possible to greatly improve work
convenience at the time of repair.
The module body portion 402 is disposed horizontally,

link body 245. Unlike this embodiment, the second driving
link shaft 242 may be manufactured integrally with the
second vane link 260.
In this embodiment, the second driving link shaft 242
D is disposed at the second driving link body 247. The second
driving link shaft 242 is disposed opposite the first
driving link shaft 241 on the basis of the core link shaft
243.
<Construction of first vane link>
In this embodiment, the first vane link 250 is made of
a strong material, and is formed in the shape of a straight
line. Unlike this embodiment, the first vane link 250 may
be curved.
The first vane link 250 includes a first vane link
body 255 made of a strong material, a 1-1 vane link shaft
251 disposed at one side of the first vane link body 255,
the 1-1 vane link shaft being assembled to the first vane
210 (specifically, a second joint portion 217), the 1-1 vane
link shaft being configured to be rotated relative to the
first vane 210, a 1-1 vane link shaft installation portion
88264224.1
253 disposed at one side of the first vane link body 255,
the 1-1 vane link shaft installation portion being formed so
as to extend from the first vane link body 255 toward the
first vane 210, the 1-1 vane link shaft 251 being disposed
D at the 1-1 vane link shaft installation portion, a 1-2 vane
link shaft 252 disposed at the other side of the first vane
link body 255, the 1-2 vane link shaft being assembled to
the module body 400 (specifically, the link installation
portion 404), the 1-2 vane link shaft being configured to be
D rotated relative to the module body 400, and a 1-2 vane link
shaft installation portion 254 disposed at the other side of
the first vane link body 255, the 1-2 vane link shaft
installation portion being formed so as to extend from the
first vane link body 255 toward the module body 400
D (specifically, the first vane link coupling portion 408),
the 1-2 vane link shaft 252 being disposed at the 1-2 vane
link shaft installation portion 253.
The 1-1 vane link shaft 251 protrudes toward the first
vane 210. The 1-1 vane link shaft 251 may be assembled to
the first vane 210, and may be rotated relative to the first
vane 210.
The 1-2 vane link shaft 252 is assembled to the link
installation portion 404 of the module body 400.
Specifically, the 1-2 vane link shaft 252 may be assembled
to the first vane link coupling portion 408, and may be
88264224.1 rotated relative to the first vane link coupling portion
408.
The 1-1 vane link shaft 251 and the 1-2 vane link
shaft 252 protrude in opposite directions. Consequently,
the 1-1 vane link shaft installation portion 253 and the 1-2
vane link shaft installation portion 254 are disposed so as
to face in opposite directions.
In this embodiment, the longitudinal direction of the
first vane link body 255 and the disposition direction of
D the 1-1 vane link shaft installation portion 253 are
perpendicular to each other, and the longitudinal direction
of the first vane link body 255 and the disposition
direction of the 1-2 vane link shaft installation portion
254 are perpendicular to each other.
The 1-1 vane link shaft installation portion 253 is
formed in a disc shape. The 1-1 vane link shaft
installation portion 253 is formed so as to be wider than
the diameter of the 1-1 vane link shaft 251. The 1-1 vane
link shaft installation portion 253 is in tight contact with
the first vane 210, and may support the first vane 210.
The 1-1 vane link shaft 251 is an axial rotation
structure for rotation with the first vane 210.
The 1-1 vane link shaft 251 includes a plurality of
link shaft bodies 251a protruding from the 1-1 vane link
shaft installation portion 253 toward the first vane 210 and
88264224.1 a link shaft catching portion 251b protruding from each of the link shaft bodies 251a, the link shaft catching portion being configured to perform mutual catching with a second joint portion 217 of the first vane 210, a description of which will follow.
In this embodiment, three link shaft bodies 251a are
provided, and the three link shaft bodies 251a are disposed
so as to be spaced apart from each other. Each link shaft
body 251a is formed so as to protrude from the 1-1 vane link
D shaft installation portion 253. The three link shaft bodies
251a constitute a cylindrical axial rotation structure.
The link shaft catching portion 251b is disposed at
each link shaft body 251a. The link shaft catching portion
251b is disposed at the outer surface of the link shaft body
251a, and protrudes outwards. The link shaft catching
portion 251b is disposed at the tip end of the link shaft
body 251a.
A joint rib 214, a description of which will follow,
is inserted between the link shaft catching portion 251b and
the 1-1 vane link shaft installation portion 253.
When the 1-1 vane link shaft 251 and the joint rib 214
are assembled, the link shaft body 251a may be deformed and
inserted into the second joint portion 217. After extending
through the second joint portion 217, the link shaft body
251a returns to the original state thereof.
88264224.1
A protrusion 253a is formed on the 1-1 vane link shaft
installation portion 253. The protrusion 253a is in tight
contact with the outer surface of the joint rib 214, and
supports the joint rib 214. The protrusion 253a may
minimize an assembly error between the first vane 210 and
the joint rib 214.
The construction of the 1-2 vane link shaft 252 is
identical to the construction of the 1-1 vane link shaft
251, and therefore a detailed description thereof will be
D omitted.
The 1-2 vane link shaft 252 includes a plurality of
link shaft bodies 252a protruding from the 1-2 vane link
shaft installation portion 254 toward the link installation
portion 404 (specifically, the first vane link coupling
D portion 408) and link shaft catching portions 252b
protruding from the link shaft bodies 252a, the link shaft
catching portions being configured to perform mutual
catching with the first vane link coupling portion 408.
<Construction of second vane link>
In this embodiment, the second vane link 260 is made
of a strong material, and is formed in the shape of a
straight line. Unlike this embodiment, the first vane link
250 may be curved.
The second vane link 260 includes a second vane link
body 265, a 2-1 vane link shaft 261 disposed at one side of
88264224.1 the second vane link body 265, the 2-1 vane link shaft being assembled to the second vane 220, the 2-1 vane link shaft being configured to be rotated relative to the second vane
220, a 2-1 vane link shaft installation portion 263
D extending from the second vane link body 265 toward the
second vane 220, the 2-1 vane link shaft 261 being disposed
at the 2-1 vane link shaft installation portion, and a 2-2
vane link journal 262 disposed at the other side of the
second vane link body 265, the 2-2 vane link journal being
D assembled to the driving link 240 (specifically, the second
driving link shaft 242), the 2-2 vane link journal being
configured to be rotated relative to the driving link 240.
In this embodiment, the 2-2 vane link journal 262 is
formed in the shape of a hole formed through the second vane
link body 265. The 2-2 vane link journal 262 and the second
driving link shaft 242 are assembled to each other to
constitute a relatively rotatable axial rotation structure.
In the case in which one of the 2-2 vane link journal
262 and the second driving link shaft 242 is formed in the
shape of a shaft, therefore, the other may be formed in the
shape of a hole or boss having the center of rotation.
Unlike this embodiment, therefore, the 2-2 vane link journal
may be formed in the shape of a shaft, and the second
driving link shaft may be formed in the shape of a hole.
In all constructions that can be coupled to the
88264224.1 driving link, the first vane link, and the second vane link so as to be rotated relative thereto, substitution of the above construction is possible, and therefore a description of modifiable examples thereof will be omitted.
The 2-1 vane link shaft 261 protrudes toward the
second vane 220. The 2-1 vane link shaft 261 may be
assembled to the second vane 220, and may be rotated
relative to the second vane 220.
In this embodiment, the longitudinal direction of the
D second vane link body 265 and the disposition direction of
the 2-1 vane link shaft installation portion 263 are
perpendicular to each other.
The 2-1 vane link shaft installation portion 263 is
formed in a disc shape. The 2-1 vane link shaft
installation portion 263 is formed so as to be wider than
the diameter of the 2-1 vane link shaft 261. The 2-1 vane
link shaft installation portion 263 is in tight contact with
the second vane 220, and may support the second vane 220.
The 2-1 vane link shaft 261 is an axial rotation
structure for rotation with the second vane 220. The 2-1
vane link shaft 261 is formed so as to have a cylindrical
structure. A link shaft catching portion 261b is formed at
the outer circumferential surface of the 2-1 vane link shaft
261. The link shaft catching portion 261b performs mutual
catching with the second vane 220.
88264224.1
The 2-1 vane link shaft 261 extends through the second
vane 220. A second joint rib 224 (specifically, a third
joint portion 226) of the second vane 220 is located between
the link shaft catching portion 261b and the 2-1 vane link
shaft installation portion 263.
A protrusion 263a is formed on the 2-1 vane link shaft
installation portion 263. The protrusion 263a is in tight
contact with the outer surface of the second vane 220
(specifically, the second joint rib 224), and supports the
D outer surface of the second vane 220 (specifically, the
second joint rib 224). The protrusion 263a may minimize an
assembly error between the second vane 220 and the 2-1 vane
link shaft installation portion 263.
In this embodiment, only a single link shaft catching
D portion 261b is formed. The link shaft catching portion
261b functions as a key. When the 2-1 vane link shaft 261
and the second vane 220 are assembled, the link shaft
catching portion 261b must extend through a key recess 224b
of the second joint rib 224 in order to assemble the second
joint rib 224 and the 2-1 vane link shaft 261 to each other.
When the second vane link 260 and the second joint rib
224 are rotated relative to each other, the link shaft
catching portion 261b and the key recess 224b are not
aligned. The position at which the link shaft catching
portion 261b and the key recess 224b are assembled deviates
88264224.1 from the operational range of the second vane link 260.
In this embodiment, the 2-2 vane link journal 262 is
formed in the shape of a hole formed through the second vane
link body 265. The key recess 262b is formed in the
longitudinal direction of the 2-2 vane link journal 262.
When the second driving link shaft 242 of the driving link
240 is assembled, the link shaft catching portion 242b of
the driving link 240 extends through the key recess 262b.
When the link shaft catching portion 242b is rotated
D after extending through the key recess 262b, the second vane
link 260 and the second driving link shaft 242 are assembled
to each other, and separation of the second driving link
shaft 242 in the insertion direction is prevented. That is,
only when the link shaft catching portion 242b is aligned
with the key recess 262b, the second driving link shaft 242
and the second vane link 260 may be separated from each
other. The second driving link shaft 242 may be rotated
relative to the 2-2 vane link journal 262 in the state of
being assembled thereto.
<Construction of vane>
For description, the direction in which air is
discharged is defined as the front, and the direction
opposite thereto is defined as the rear. In addition, the
ceiling side is defined as the upper side, and the floor is
defined as the lower side.
88264224.1
In this embodiment, the first vane 210 and the second
vane 220 are disposed in order to control the flow direction
of air that is discharged from the discharge port 102. The
relative disposition and relative angle between the first
vane 210 and the second vane 220 are changed according to
steps of the vane motor 230. In this embodiment, the first
vane 210 and the second vane 220 provide six discharge steps
P1, P2, P3, P4, P5, and P6 in pairs according to steps of
the vane motor 230.
D The discharge steps P1, P2, P3, P4, P5, and P6 are
defined as states in which the first vane 210 and the second
vane 220 are stationary, rather than moved. In this
embodiment, on the other hand, moving steps may be provided.
The moving steps result from a combination of the six
discharge steps P1, P2, P3, P4, P5, and P6, and are defined
as the current of air provided by the operation of the first
vane 210 and the second vane 220.
<Construction of first vane>
The first vane 210 is disposed between the link
installation portion 404 of the first module body 410 and
the link installation portion 404 of the second module body
420.
When the indoor unit is not operated, the first vane
210 covers most of the discharge port 210. Unlike this
embodiment, the first vane 210 may be manufactured so as to
88264224.1 cover the entirety of the discharge port 210.
The first vane 210 is coupled to the driving link 240
and the first vane link 250.
The driving link 240 and the first vane link 250 are
disposed at one side and the other side of the first vane
210, respectively.
The first vane 210 is rotated relative to the driving
link 240 and the first vane link 250.
When it is necessary to distinguish between the
D positions of the driving link 240 and the first vane link
250, the driving link 240 coupled to the first module body
410 is defined as a first driving link, and the first vane
link 250 coupled to the first module body 410 is defined as
a 1-1 vane link. The driving link 240 coupled to the second
module body 420 is defined as a second driving link, and the
first vane link 250 coupled to the second module body 420 is
defined as a 1-2 vane link.
The first vane 210 includes a first vane body 212
formed so as to extend long in the longitudinal direction of
the discharge port 102 and a joint rib 214 protruding
upwards from the first vane body 212, the driving link 240
and the first vane link 250 being coupled to the joint rib.
The first vane body 212 controls the direction of air
that is discharged along the discharge channel 104. The
discharged air collides with the upper surface or the lower
88264224.1 surface of the first vane body 212, whereby the flow direction thereof may be guided. The discharge direction of air and the longitudinal direction of the first vane body
212 are perpendicular to or intersect each other.
D The lower surface of the first vane body 212 is formed
as a smooth flat or curved surface, various structures,
including the joint rib 214, are disposed at the upper
surface thereof. The flat surface of the first vane body
212 corresponds to the shape of the discharge port 102.
D The joint rib 214 is an installation structure for
coupling between the driving link 240 and the first vane
link 250. The joint rib 214 is disposed at each of one side
and the other side of the first vane 210.
The joint rib 214 is formed so as to protrude upwards
from the upper surface of the first vane body 212. The
joint rib 214 is formed in the flow direction of discharged
air, and minimizes resistance to the discharged air.
Consequently, the joint rib 214 is perpendicular to or
intersects the longitudinal direction of the first vane body
212.
The joint rib 214 is formed such that the air
discharge side (the front) of the joint rib is low and the
air entrance side (the rear) of the joint rib is high. In
this embodiment, the joint rib 214 is formed such that the
side of the joint rib to which the driving link 240 is
88264224.1 coupled is high and the side of the joint rib to which the first vane link 250 is coupled is low.
The joint rib 214 has a second joint portion 217
rotatably coupled with the driving link 240 and a first
joint portion 216 rotatably coupled with the first vane link
250.
The joint rib 214 may be manufactured integrally with
the first vane body 212.
In this embodiment, each of the first joint portion
D 216 and the second joint portion 217 is formed in the shape
of a hole, and is formed through the joint rib 214.
Each of the first joint portion 216 and the second
joint portion 217 is a structure in which axial coupling or
hinge coupling is possible, and may be changed into any of
D various forms.
When viewed from the front, the second joint portion
217 is located higher than the first joint portion 216.
The second joint portion 217 is located further
rearwards than the first joint portion 216. The first
driving link shaft 241 is assembled to the second joint
portion 217. The second joint portion 217 and the first
driving link shaft 241 are assembled so as to be rotatable
relative to each other. In this embodiment, the first
driving link shaft 241 is assembled through the second joint
portion 217.
88264224.1
The 1-1 vane link shaft 251 is assembled to the first
joint portion 216.
The first joint portion 216 and the 1-1 vane link
shaft 251 are assembled so as to be rotatable relative to
D each other. In this embodiment, the 1-1 vane link shaft 251
is assembled through the first joint portion 216.
When viewed in a top view, the driving link 250 and
the first vane link 250 are disposed between the joint rib
214 and the link installation portion 404. In this
D embodiment, the distance between the first joint portion 216
and the second joint portion 217 is less than the distance
between the core link shaft 243 and the 1-2 vane link shaft
252.
Two joint ribs 214 are disposed at the first vane 210.
When it is necessary to distinguish between the two joint
ribs 214 disposed at the first vane 210, the joint rib 214
disposed at the left side of the vane module is defined as a
1-1 joint rib 214-1, and the joint rib disposed at the right
side of the vane module is defined as a 1-2 joint rib 214-2,
when viewed from the front of the vane module.
The left joint portion 214-1 and the right joint
portion 214-2 of the first vane 210 are disposed parallel to
each other.
A concave recess 215-1 is formed outside the 1-1 joint
rib 214-1 of the first vane 210, and a concave recess 215-2
88264224.1 is also formed outside the 1-2 joint rib 214-2 of the first vane.
The recess 215-1 extends long from the 1-1 joint rib
214-1 in the longitudinal direction of the first vane 210.
The recess 215-2 extends long from the 1-2 joint rib 214-2
in the longitudinal direction of the first vane 210.
The recess 215-1 is located outside of the first joint
portion 216 of the 1-1 joint rib 214-1, and the recess 215-2
is located outside of the first joint portion 216 of the 1-2
D joint rib 214-1. The recesses 215-1 and 215-2 are disposed
on the same line.
Interference between the first vane link 250 and the
first vane body 212 may be avoided by the recesses 215-1 and
215-2.
D An air guide 280 is disposed between the 1-1 joint rib
214-1 and the 1-2 joint rib 214-2. The air guide 280 is
formed integrally with the first vane body 212. Unlike this
embodiment, the air guide 280 may be separately manufactured
and then assembled to the first vane body 212.
The air guide 280 extends in the longitudinal
direction of the first vane body 212.
The air guide 280 includes a first connection guide
281 disposed at the 1-1 joint rib 214-1 side, the first
connection guide extending upwards from the upper surface of
the first vane body 212, a second connection guide 282
88264224.1 disposed at the 1-2 joint rib 214-2 side, the second connection guide extending upwards from the upper surface of the first vane body 212, a main guide 285 configured to connect the first connection guide 281 and the second
D connection guide 282 to each other, the main guide being
disposed so as to be spaced apart from the upper surface of
the first vane body 212, and a support guide 286 configured
to connect the main guide 285 and the first vane body 212 to
each other.
D The air guide 280 is disposed between the 1-1 joint
rib 214-1 and the 1-2 joint rib 214-2. The air guide 280 is
located further forwards than the first joint portion 216.
The first connection guide 281 is curved in order to
minimize air resistance. The first connection guide 281 is
D curved in the longitudinal direction of the first vane 210.
The second connection guide 282 is also curved in the
longitudinal direction of the first vane 210.
The first connection guide 281 and the second
connection guide 282 are disposed so as to face each other.
The first connection guide 281 is disposed so as to
face the 1-2 joint rib 214-2, and the second connection
guide 282 is disposed so as to face the 1-1 joint rib 214-1.
The left side of the main guide 285 is connected to
the first connection guide 281, and the right side of the
main guide 285 is connected to the second connection guide
88264224.1
282. The main guide 285 is spaced apart from the upper
surface of the first vane body 212. Discharged air may be
guided between the main guide 285 and the upper surface of
the first vane body 212.
D The space between the main guide 285 and the first
vane body 212 is defined as a guide space 283. The guide
space 283 may extend long in the longitudinal direction of
the first vane body 212.
The support guide 286 partitions the guide space 283
D into left and right spaces. A plurality of support guides
286 is disposed, and the guide space 283 is partitioned into
a plurality of spaces by the support guides 286.
The support guide 286 connects the upper surface of
the first vane body 212 and the lower surface of the main
D guide 285 to each other. A plurality of support guides 286
is disposed in the longitudinal direction of the first vane
body 210 so as to be spaced apart from each other by a
predetermined distance.
In this embodiment, seven support guides 286 are
disposed, and an odd number of support guides is disposed
such that the number of left guide spaces 283 is equal to
the number of right guide spaces. The left guide spaces and
the right guide spaces are symmetrical with respect to the
intermediate support guide 286.
The support guide 286 is disposed so as to be
88264224.1 perpendicular to the first vane body 212.
The rear end of the support guide 286 may have a tail
extending long toward the rear of the first vane 210 (in the
direction opposite the discharge direction of air). This is
defined as a support guide tail 287. The support guide tail
287 is disposed in the forward-rearward direction of the
support guide 286, and is formed such that the height
thereof gradually decreases from the upper side of the
support guide 286 to the first vane body 212.
D The rear end of the support guide tail 287 is located
further rearwards than the rear edge 285b of the main guide
285.
The length from the support guide 286 to the support
guide tail 287 is greater than the forward-rearward length
of the main guide 285.
A recess line 218 is formed concave downwards from the
upper surface of the first vane body 212. A plurality of
recess lines 218 is disposed.
The recess line 218 is formed along the front end 212a
of the first vane 210, and a plurality of recess lines is
formed rearwards from the front end 212a of the first vane
body in order to form a row. In this embodiment, the recess
lines 218 are disposed in three rows.
The first row of the recess lines 218 is located the
closest to the front end 212a of the first vane body, and
88264224.1 has the largest length. The third row of the recess lines
218 is located farthest from the front end 212a of the first
vane body, and has the smallest length. The second row of
the recess lines 218 is shorter than the first row and
longer than the third row.
The third row of the recess lines 218 is located
further forwards than the front edge 285a of the main guide
285.
The plurality of recess lines 218 may improve flow of
D discharged air.
<Construction of second vane>
The second vane 220 is formed so as to have a smaller
area than the first vane 210. When controlling the
discharge direction of air, the second vane 220 has less
influence than the first vane 210. In this embodiment, the
first vane 210 serves as a main vane that controls the
discharge direction of air, and the second vane 220 serves
as a sub vane.
The second vane 220 is installed in the discharge
channel 104, and is rotated about the second vane shaft 221.
Depending on the rotational angle of the second vane 220,
the front end 222a of the second vane 220 may be located
outside the discharge port 102.
In this embodiment, the second vane 220 is made of a
transparent or semitransparent material.
88264224.1
The second vane 220 includes a second vane body 222
formed so as to extend long in the longitudinal direction of
the discharge port 102, a joint rib 224 protruding upwards
from the second vane body 222, the joint rib being coupled
D to the second vane link 260 so as to be rotatable relative
thereto, and a pair of second vane shafts 221 formed at one
side and the other side of the second vane body 222, the
second vane shafts being rotatably coupled to the link
installation portion 404 (specifically, the second vane
D coupling portion 409).
The second joint rib 224 is coupled to the second vane
link 260 so as to be rotatable relative thereto. In this
embodiment, the third joint portion 226 and the second vane
link 260 are axially coupled to each other so as to be
rotatable relative thereto.
The second joint rib 224 is formed so as to protrude
upwards from the upper surface of the second vane body 222.
The second joint rib 224 is preferably formed in the flow
direction of discharged air. Consequently, the second joint
rib 224 is disposed so as to perpendicular to or intersect
the longitudinal direction of the second vane body 222.
The second vane shaft 221 includes a 2-1 vane shaft
221-1 and a 2-2 vane shaft 221-2. The 2-1 vane shaft 221-1
and the 2-2 vane shaft 221-2 are located on a straight line,

The permanent magnet 318 and the magnetic force fixing
88264224.1 portion 328 are located at the upper side of each grill corner portion 327, and are hidden by each grill corner portion 327. Since the permanent magnet 318 and the magnetic force fixing portion 328 are located outside each
D corner of the suction grill 320, the distance between the
suction grill 320 and the front body 310 may be minimized.
In the case in which the suction grill 320 and the
front body 310 are spaced apart from each other, pressure in
the suction channel 103 is reduced.
D In this embodiment, the permanent magnet 318 is
disposed at the front body 310. Specifically, the permanent
magnet is disposed at the corner frame 313.
The magnetic force fixing portion 328 is made of a
metal material capable of generating attractive force

magnetic force fixing portion 328 is disposed at the upper
surface of the suction grill 320. Specifically, the
magnetic force fixing portion 328 is disposed at the upper
surface of the grill corner portion 327.
When the suction grill 320 is moved upwards and
approaches the permanent magnet 318, the permanent magnet
318 attracts the magnetic force fixing portion 328 to fix
the suction grill 320. Magnetic force of the permanent
magnet 318 is less than weight of the suction grill 320.
When the suction grill 320 is not pulled by the elevator
88264224.1
500, therefore, coupling between the permanent magnet 318
and the magnetic force fixing portion 328 is released.
When viewed in a top view or a bottom view, the
permanent magnet 318 is disposed on the imaginary diagonal
lines P1 and P2. The permanent magnet 318 is located inside
the corner cover 316.
When viewed in a top view or a bottom view, one of

module body 410 of the first vane module 201 and the second
D module body 420 of the fourth vane module 204. The other
three permanent magnets are also disposed between the first
module bodies 410 and the second module bodies 420 of the
respective vane modules.
The permanent magnet 318 and the magnetic force fixing
D portion 328 are located at the upper side of each grill
corner portion 327, and are hidden by each grill corner
portion 327.

operated (the indoor blowing fan is not operated), in each
vane module 200, as shown, the second vane 220 is located at
the upper side of the first vane 210, and the first vane 210
covers the discharge port 102. The lower surface of the
first vane 210 forms a continuous surface with the lower
surface of the suction grill 320 and the lower surface of
88264224.1 the side cover 314.
When the indoor unit is not operated, the second vane
220 is concealed when viewed from the outside, since the
second vane is located at the upper side of the first vane
210. Only when the indoor unit is operated, the second vane
220 is exposed to the user. When the indoor unit is not
operated, therefore, the second vane 220 is located in the
discharge channel 104, and the first vane 210 covers most of
the discharge port 102.
Although the first vane 210 covers most of the
discharge port 102 in this embodiment, the first vane 210
may be formed so as to cover the entirety of the discharge
port 102 depending on design.
When the indoor blowing fan is operated in the state
in which the second vane 220 is received, the vane motor 230
is operated, and the first vane 210 and the second vane 220
may provide one of the six discharge steps P1, P2, P3, P4,
P5, and P6.
The state in which the indoor unit is stopped and thus
the vane module 200 is not operated is defined as a stop
step P0.
<Stop step P0>
In stop step P0, the vane module 200 is not operated.
When the indoor unit is not operated, the vane module 200 is
maintained in stop step P0.
88264224.1
In stop step P0, in the vane module 200, the vane
motor 230 maximally rotates the driving link 240 in a first
direction (in the clockwise direction in the figures of this
embodiment).
D At this time, the second driving link body 247
constituting the driving link 240 is supported by one end
271 of the stopper 270, whereby further rotation of the
driving link in the first direction is limited.
In order to prevent excessive rotation of the driving
D link 240, the second driving link body 247 and the other end
270b of the stopper 270 interfere with each other in stop
step P0. The second driving link body 247 is supported by
the stopper 270, whereby further rotation of the driving
link is limited.
The driving link 240 is rotated about the core link
shaft 243 in the first direction, and the first vane link
250 is rotated about the 1-2 vane link shaft 252 in the
first direction.
The first vane 210 is rotated while being restrained
by the driving link 240 and the first vane link 250, and is
located in the discharge port 102. The lower surface of the
first vane 210 forms a continuous surface with the suction
panel 320 and the side cover 314.
In stop step P0, the second vane 220 is located at the
upper side of the first vane 210. When viewed from above,
88264224.1 the second vane 220 is located between the first joints 214, and is located at the upper side of the first vane body 212.
In stop step P0, the driving link 240, the first vane
link 250, and the second vane link 260 are located at the
D upper side of the first vane 210. The driving link 240, the
first vane link 250, and the second vane link 260 are hidden
by the first vane 210 and thus are not visible from the
outside. That is, in stop step P0, the first vane 210
covers the discharge port 102, and prevents parts
D constituting the vane module 200 from being exposed outside.
In stop step P0, the driving link 240 is maximally
rotated in the clockwise direction, and the second vane line
260 is maximally moved upwards.
When the indoor unit is not operated, the second vane
220 is concealed when viewed from the outside, since the
second vane is located at the upper side of the first vane
210. Only when the indoor unit is operated, the second vane
220 is exposed to the user.
The positional relationship between the shafts forming
the centers of rotation of the respective links in stop step
P0 will be described.
First, the first joint portion 216 and the second
joint portion 217 of the first vane 210 are disposed
approximately horizontally. The second joint rib 224 of the
second vane 220 is located at the upper side of the first
88264224.1 joint rib 214.
When viewed from the side, the second joint rib 224 is
located at the upper side of the second joint portion 217
and the first joint portion 216, and is located between the
first joint portion 216 and the second joint portion 217.
Since the 2-1 vane link shaft 261 is coupled to the
second joint rib 224, the 2-1 vane link shaft 261 is also
located at the upper side of the second joint portion 217
and the first joint portion 216.
D The first joint portion 216 and the second joint
portion 217 are located at the upper side of the first vane
body 212, and are located at the lower side of the second
vane body 222.
The 2-2 vane link journal 262 is located at the upper
side of the 2-1 vane link shaft 261, and is located at the
upper side of the core link shaft 243.
Next, relative positions and directions of the
respective links in stop step PO will be described.
The first vane link 250 and the second vane link 260
are disposed in the same direction. The upper end of each
of the first vane link 250 and the second vane link 260 is
located at the front side in the discharge direction of air,
and the rear end thereof is located at the rear side in the
discharge direction of air.
Specifically, the 1-2 vane link shaft 252 of the first
88264224.1 vane link 250 is located at the front side, and the 1-1 vane link shaft 251 of the first vane link 250 is located at the rear side. The 1-2 vane link shaft 252 of the first vane link 250 is located higher than the 1-1 vane link shaft 251.
The first vane link 250 is disposed so as to be inclined
rearwards and downwards from the 1-2 vane link shaft 252.
In the same manner, the 2-2 vane link journal 262 of
the second vane link 260 is located at the front side, and
the 2-1 vane link shaft 261 of the second vane link 260 is
D located at the rear side. The 2-2 vane link journal 262 of
the second vane link 260 is located higher than the 2-1 vane
link shaft 261. The second vane link 260 is disposed so as
to be inclined rearwards and downwards from the 2-2 vane
link journal 262.
The first driving link body 246 of the driving link
240 is disposed in the same direction as the first vane link
250 and the second vane link 260, and the second driving
link body 247 intersects the disposition direction of the
first vane link 250 and the second vane link 260.
<Discharge step P1>
In stop step P0, the driving link 240 is rotated in a
second direction (in the counterclockwise direction in the
figures of this embodiment), which is opposite the first
direction, to provide discharge step Pl.
In discharge step P1, the vane module 200 may provide
88264224.1 horizontal wind.
In the state of the horizontal wind, air discharged
from the discharge port 102 may be guided by the first vane
210 and the second vane 220 and may flow in the direction
D parallel with the ceiling or the floor.
In the case in which the discharged air flows as the
horizontal wind, it is possible to maximize the flow
distance of the air.
In discharge step P1, the upper surfaces of the first
D vane 210 and the second vane 220 may form a continuous
surface. In discharge step P1, the first vane 210 and the
second vane 220 are connected to each other like a single
vane, and guide the discharged air.
In this embodiment, the first vane 210 is located at
the front side in the flow direction of the discharged air,
and the second vane 220 is located at the rear side in the
flow direction of the discharged air. The front end 222a of
the second vane 220 may be adjacent to or may contact the
rear end 212b of the first vane 210. In discharge step P1,
the distance Si between the front end 222a of the second
vane 220 and the rear end 212b of the first vane 210 may be
minimized.
In discharge step P1, the front end 222a of the second
vane 220 is located higher than the rear end 212b of the
first vane 210.
88264224.1
In the case in which the front end 222a and the rear
end 212b are adjacent to or contact each other, leakage of
the discharged air between the first vane 210 and the second
vane 220 may be minimized.
In this embodiment, the front end 222a and the rear
end 212b are adjacent to each other, but do not contact each
other.
When the vane module 200 forms the horizontal wind in
discharge step P1, intensity of the horizontal wind may be
D increased, since the first vane 210 and the second vane 220
are connected to each other and operated like a single vane.
That is, since the discharged air is guided along the upper
surface of the second vane 220 and the upper surface of the
first vane 210 in the horizontal direction, directivity of
the discharged air may be further improved than the case in
which the horizontal wind is formed using a single vane.
When forming the horizontal wind, the second vane 220
is disposed so as to be further inclined in the upward
downward direction than the first vane 210.
In the state of the horizontal wind, it is
advantageous that the first vane 210 be located lower than
the discharge port 102 and the second vane 220 be disposed
so as to overlap the discharge port 102, when viewed from
the side.
In discharge step P1, the second vane 220 is rotated
88264224.1 in place about the second vane shaft 221; however, the first vane 210 is turned (swung) in the discharge direction of air, since the first vane is assembled to the driving link
240 and the first vane link 250.
When PO is switched to P1, the second vane 220 is
rotated about the second vane shaft 221, the first vane 210
is moved downwards while advancing in the discharge
direction of air, and the front end 212a of the first vane
is turned in the first direction (the clockwise direction in
D the figures).
Through rotation of the driving link 240 and the first
vane link 250, the first vane 210 may be moved to the lower
side of the discharge port 102, and the first vane 210 may
be disposed approximately horizontally. Since a vane of a
D conventional indoor unit is rotated in place, it is not
possible to realize disposition of the first vane 210 in
this embodiment.
When the vane motor 230 rotates the driving link 240
in the second direction (the counterclockwise direction) in
stop step P0, the second vane link 260 coupled to the
driving link 240 is rotated in response to the driving link
240.
Specifically, when stop step P0 is switched to
discharge step P1, the driving link 240 is rotated in the
counterclockwise direction, the first vane line 210 is
88264224.1 rotated in the counterclockwise direction in response to rotation of the driving link 240, and the second vane link
220 is moved downwards while being rotated relative thereto.
Since the second vane 220 is assembled to the second
D vane shaft 221 and the second vane link 260 so as to be
rotatable relative thereto, the second vane is rotated about
the second vane shaft 221 in the clockwise direction due to
downward movement of the second vane link 220.
When stop step PO is switched to discharge step P1 in
D order to form the horizontal wind, the first vane 210 and
the second vane 220 are rotated in opposite directions.
In discharge step P1, the vane motor 230 is rotated 73
degrees (P1 rotational angle), and the first vane 210 has an
inclination of about 13 degrees (first vane P1 inclination)
D and the second vane 220 has an inclination of about 52
degrees (second vane P1 inclination) by rotation of the vane
motor 230.
The positional relationship between the shafts forming
the centers of rotation of the respective links in discharge
step P1 will be described.
First, the second joint portion 217 and the first
joint portion 216 of the first vane 210 are disposed so as
to be inclined forwards in the discharge direction of air,
unlike PO. When viewed from the side, the third joint
portion 226 of the second vane 220 is disposed at the
88264224.1 rearmost side, the first joint portion 216 is disposed at the frontmost side, and the second joint portion 217 is disposed between the first joint portion 216 and the third joint portion 226.
D In P1, the third joint portion 226, the second joint
portion 217, and the first joint portion 216 are disposed in
a line, and are disposed so as to face forwards and
downwards in the discharge direction of air. In some
embodiments, the third joint portion 226, the second joint
D portion 217, and the first joint portion 216 may not be
disposed in a line.
In addition, the second vane shaft 221 may also be
disposed in a line with the third joint portion 226, the
second joint portion 217, and the first joint portion 216.
D In this case, the second vane shaft 221 is located at the
rear side of the third joint portion 226.
In P1, the first vane 210 and the second vane 220
provide horizontal wind. The horizontal wind does not mean
that the discharge direction of air is exactly horizontal.
The horizontal wind means an angle by which discharged air
can flow farthest in the horizontal direction through
connection between the first vane 210 and the second vane
220 in the state in which the first vane 210 and the second
vane 220 are connected to each other like a single vane.
In discharge step P1, the distance Si between the
88264224.1 front end 221 of the second vane 220 and the rear end 212b of the first vane 210 may be minimized.
In the state of the horizontal wind, air guided by the
second vane 220 is guided to the first vane 210. In the
D case in which the discharged air flows as the horizontal
wind in P1, it is possible to maximize the flow distance of
the air.
Since the discharge channel 104 is formed in the
upward-downward direction, the inclination of the second
D vane 220 adjacent to the suction port 101 is steeper than
the inclination of the first vane 210.
In discharge step P1, the 1-1 vane link shaft 251 of
the first vane link 250 is located at the lower side of the
1-2 vane link shaft 252.
In discharge step P1, the 2-1 vane link shaft 261 of
the second vane link 260 is located at the lower side of the
2-2 vane link journal 262.
In discharge step P1, the first driving link shaft 241
of the driving link 240 is located at the lower side of the
second driving link shaft 242 and the core link shaft 243.
In discharge step P1, in the upward-downward
direction, the third joint portion 226 is located at the
uppermost side, the first joint portion 216 is located at
the lowermost side, and the second joint portion 217 is
located therebetween.
88264224.1
In discharge step P1, the first joint portion 216 and
the second joint portion 217 are located between the core
link shaft 243 and the 1-2 vane link shaft 252.
In discharge step P1, the first driving link shaft 241
D and the 1-1 vane link shaft 251 are located at the lower
side of the suction panel 320. In discharge step P1, the
first driving link shaft 241 and the 1-1 vane link shaft 251
are located at the lower side of the discharge port 102.
The 2-1 vane link shaft 261 is located over the border of
D the discharge port 102.
Due to the above disposition, the first vane 210 is
located at the lower side of the discharge port 102 in
discharge step Pl. In discharge step P1, the front end 222a
of the second vane 220 is located at the lower side of the
discharge port 102, and the rear end 222b thereof is located
at the upper side of the discharge port 102.
Next, relative positions and directions of the
respective links in discharge step P1 will be described.
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 Li-Li'. The
longitudinal direction of the second vane link 260 is
defined as L2-L2'.
In discharge step P1, the first vane link 250, the
second vane link 260, and the first driving link body 246
88264224.1 are disposed 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 disposed in the upward downward direction in discharge step Pl.
D Specifically, Li-Li' of the first vane link 250 is
disposed almost vertically, and L2-L2' of the second vane
link 260 is disposed almost vertically. D-D' of the first
driving link body 246 is disposed so as to face downwards in
the discharge direction of air.
D In discharge step P1, the first vane 210 is located at
the lower side of the discharge port 102, and the front end
222a of the second vane 220 is located at the lower side of
the discharge port 102. That is, in the state of the
horizontal wind, only a portion of the second vane 220 is
located outside the discharge port 102, and the entirety of
the first vane 210 is located outside the discharge port
102.
In discharge step P1, the front end 212a of the first
vane 210 is located further forwards than the front edge
102a of the discharge port 102 on the basis of the discharge
port 102.
<Discharge step P2>
In the state of the horizontal wind of discharge step
P1, the driving link 240 may be rotated in the second
direction (in the counterclockwise direction in the figures
88264224.1 of this embodiment), which is opposite the first direction, to provide discharge step P2.
In discharge step P2, the vane module 200 may provide
inclined wind. The inclined wind is defined as a discharge
D step between horizontal wind and vertical wind. In this
embodiment, the inclined wind means discharge steps P2, P3,
P4, and P5.
In the state of the inclined wind, air is discharged
further downwards than in the state of the horizontal wind
D of discharge step Pl. In discharge step P2, both the first
vane 210 and the second vane 220 are adjusted so as to face
further downwards than in discharge step Pl.
In 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 greater than the distance Si in
discharge step Pl.
That is, when discharge step P1 is switched to P2, the
distance between the front end 222a of the second vane 220
and the rear end 212b of the first vane 210 further
increases. In discharge step P2, the first vane 210 and the
second vane 220 are disposed further vertically than in Pl.
When discharge step P1 is switched to discharge step
P2, the front end 222a of the second vane 220 is moved
downwards, and the rear end 212b of the first vane 210 is
moved upwards.
88264224.1
In discharge step P2, the front end 222a of the second
vane 220 and the rear end 212b of the first vane 210 are
located at similar heights.
When discharge step P1 is switched to discharge step
P2, the second vane 220 is rotated in place about the second
vane shaft 221; however, the first vane 210 is turned
(swung), since the first vane is assembled to the driving
link 240 and the first vane link 250.
In particular, when P1 is switched to P2, the first
D vane 210 further advances in the discharge direction of air,
and the front end 212a of the first vane is further turned
in the first direction (the clockwise direction in the
figures).
Since the second vane 220 is assembled to the second
D vane shaft 221 and the second vane link 260 so as to be
rotatable relative thereto, the second vane is further
rotated about the second vane shaft 221 in the clockwise
direction due to rotation of the second vane link 220.
The front end 222a of the second vane 220 is further
rotated in the second direction (the clockwise direction in
the figures) .
When discharge step P1 is switched to discharge step
P2, the first vane 210 and the second vane 220 are rotated
in opposite directions.
In discharge step P2, the vane motor 230 is rotated 78
88264224.1 degrees (P2 rotational angle), and the first vane 210 has an inclination of about 16 degrees (first vane P2 inclination) and the second vane 220 has an inclination of about 56 degrees (second vane P2 inclination) by rotation of the vane
D motor 230.
The positional relationship between the shafts forming
the centers of rotation of the respective links in discharge
step P2 will be described.
In discharge step P2, the second joint portion 217 and
D the first joint portion 216 of the first vane 210 are
disposed so as to be inclined forwards in the discharge
direction of air, similarly to Pl.
When viewed from the side, the third joint portion 226
of the second vane 220 is disposed at the rearmost side, the
first joint portion 216 is disposed at the frontmost side,
and the second joint portion 217 is disposed between the
first joint portion 216 and the third joint portion 226.
In P2, the third joint portion 226, the second joint
portion 217, and the first joint portion 216 are disposed so
as to face forwards and downwards in the discharge direction
of air, when viewed from the side of vane module 200.
In discharge step P2, the third joint portion 226 is
moved further downwards, and the first joint portion 216 and
the second joint portion 217 are moved further forwards.
That is, the distance between the second vane 220 and the
88264224.1 first vane 210 increases.
In discharge step P2, the disposition of the first
vane link 250, the second vane link 260, and the driving
link 240 is similar to that in discharge step Pl.
In discharge step P2, the 1-1 vane link shaft 251 of
the first vane link 250 is located at the lower side of the
1-2 vane link shaft 252. In discharge step P2, the 2-1 vane
link shaft 261 of the second vane link 260 is located at the
lower side of the 2-2 vane link journal 262. In discharge
D step P2, the first driving link shaft 241 of the driving
link 240 is located at the lower side of the second driving
link shaft 242 and the core link shaft 243.
In discharge step P2, the second vane shaft 221 is
located at the uppermost side, the third joint portion 226
is located at the lower side of the second vane shaft 221,
the second joint portion 217 is located is located at the
lower side of the third joint portion 226, and the first
joint portion 216 is located at the lower side of the second
joint portion 217.
In discharge step P2, the second joint portion 217 is
further rotated about the core link shaft 243 toward the 1-2
vane link shaft 252.
In discharge step P2, the entirety of the first vane
210 is located at the lower side of the discharge port 102
on the basis of the suction panel 320 or the discharge panel
88264224.1
102. In discharge step P2, the front end 222a of the second
vane 220 is located at the lower side of the discharge port
102, and the rear end 222b thereof is located at the upper
side of the discharge port 102.
In discharge step P2, therefore, the first driving
link shaft 241 and the 1-1 vane link shaft 251 are located
at the lower side of the suction panel 320. In discharge
step P2, the first driving link shaft 241 and the 1-1 vane
link shaft 251 are located at the lower side of the
D discharge port 102. The 2-1 vane link shaft 261 is located
over the border of the discharge port 102.
Next, relative positions and directions of the
respective links in discharge step P2 will be described.
In discharge step P2, the first vane link 250 and the
D second vane link 260 are disposed in approximately the same
direction, and the first driving link body 246 is disposed
so as to be inclined forwards and downwards. Particularly,
in discharge step P2, the first vane link 250 and the second
vane link 260 are disposed approximately vertically.
Specifically, when discharge step P1 is switched to
discharge step P2, Li-Li' of the first vane link 250 is
further rotated in the discharge direction of air. When
discharge step P1 is switched to discharge step P2, L2-L2'
of the second vane link 260 is further rotated in the
direction opposite the discharge direction of air. When
88264224.1 discharge step P1 is switched to discharge step P2, D-D' of the first driving link body 246 is further rotated in the discharge direction of air.
In discharge step P2, the entirety of the first vane
210 is located at the lower side of the discharge port 102,
and only the front end 222a of the second vane 220 is
located at the lower side of the discharge port 102.
When discharge step P1 is switched to discharge step
P2, the front end 212a of the first vane 210 is moved
D further forwards than the front edge 102a of the discharge
port 102 on the basis of the discharge port 102.
<Discharge step P3>
In discharge step P2, the driving link 240 may be
rotated in the second direction (in the counterclockwise
direction in the figures of this embodiment), which is
opposite the first direction, to provide discharge step P3.
In discharge step P3, the vane module 200 may provide
inclined wind that is discharged further downwards than in
discharge step P2.
In the state of the inclined wind of discharge step
P3, air is discharged further downwards than in the state of
the inclined wind of discharge step P2. In discharge step
P3, both the first vane 210 and the second vane 220 are
adjusted so as to face further downwards than in discharge
step P2.
88264224.1
In 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 greater than the distance S2 in
discharge step P2.
D That is, when discharge step P2 is switched to P3, the
distance between the front end 222a of the second vane 220
and the rear end 212b of the first vane 210 further
increases. In discharge step P3, the first vane 210 and the
second vane 220 are disposed further vertically than in P2.
D When discharge step P2 is switched to discharge step
P3, the front end 222a of the second vane 220 is moved
further downwards, and the rear end 212b of the first vane
210 is moved further upwards.
In discharge step P3, the front end 222a of the second
vane 220 is located lower than the rear end 212b of the
first vane 210.
When discharge step P2 is switched to discharge step
P3, the second vane 220 is rotated in place about the second
vane shaft 221; however, the first vane 210 is turned
(swung), since the first vane is assembled to the driving
link 240 and the first vane link 250.
When discharge step P2 is switched to discharge step
P3, the first vane 210 is located almost in place, and is
rotated in the first direction (the clockwise direction).
When discharge step P2 is switched to discharge step P3, the
88264224.1 second vane 220 is further rotated in the first direction
(the clockwise direction).
When discharge step P2 is switched to discharge step
P3, the first vane 210 is located in place in the first
direction (the clockwise direction), rather than advancing
in the discharge direction.
When discharge step P2 is switched to discharge step
P3, the front end 222a of the second vane 220 is further
rotated in the first direction (the clockwise direction) due
D to downward movement of the second vane link 220.
When discharge step P2 is switched to discharge step
P3, the first vane 210 and the second vane 220 are rotated
in opposite directions.
In discharge step P3, the vane motor 230 is rotated 95
degrees (P3 rotational angle), and the first vane 210 has an
inclination of about 29 degrees (first vane P3 inclination)
and the second vane 220 has an inclination of about 67
degrees (second vane P3 inclination) by rotation of the vane
motor 230.
The positional relationship between the shafts forming
the centers of rotation of the respective links in discharge
step P3 will be described.
In discharge step P3, the second joint portion 217 and
the first joint portion 216 of the first vane 210 are
disposed so as to be inclined forwards in the discharge
88264224.1 direction of air, similarly to P2.
When viewed from the side, the third joint portion 226
of the second vane 220 is disposed at the rearmost side, the
first joint portion 216 is disposed at the frontmost side,
D and the second joint portion 217 is disposed between the
first joint portion 216 and the third joint portion 226.
In discharge step P3, the third joint portion 226 is
moved further downwards. In discharge step P3, the first
joint portion 216 and the second joint portion 217 are moved
D upwards due to rotation of the first vane link 250 and the
first driving link body 246 in the second direction.
Since the length of the first driving link body 246 is
less than the length of the first vane link 250, the upper
side of the second joint portion 217 is higher.
In discharge step P3, the disposition of the shafts at
the driving link 240, the first vane link 250, and the
second vane link 260 is similar to that in discharge step
P2.
However, relative heights of the first driving link
shaft 241, the 1-1 vane link shaft 251, and the 2-1 vane
link shaft 261 rotated by operation of the driving link 240,
the first vane link 250, and the second vane link 260 are
varied.
In discharge step P3, the first driving link shaft 241
is moved upwards, and the 2-1 vane link shaft 261 is moved
88264224.1 downwards, whereby these shafts are located at similar heights in the upward-downward direction.
When discharge step P2 is switched to discharge step
P3, the second joint portion 217 is further rotated about
the core link shaft 243 toward the 1-2 vane link shaft 252,
and the second joint portion 217 is spaced further apart
from the 2-1 vane link shaft 261.
In discharge step P3, the 2-2 vane link journal 262 is
located lower than the core link shaft 243.
D When discharge step P2 is switched to discharge step
P3, the 2-1 vane link shaft 261 is moved further rearwards
than the 2-2 vane link journal 262.
On the basis of the suction panel 320 or the discharge
port 102, the position of the first vane 210 and the second
vane 220 in discharge step P3 is similar to that in
discharge step P2.
In discharge step P3, therefore, the first driving
link shaft 241 and the 1-1 vane link shaft 251 are located
at the lower side of the suction panel 320 and the discharge
port 102. The 2-1 vane link shaft 261 is located over the
border of the discharge port 102.
Next, relative positions and directions of the
respective links in discharge step P3 will be described.
In discharge step P3, the first vane link 250 and the
second vane link 260 are disposed in opposite directions.
88264224.1
In discharge step P3, the first driving link body 246
and the first vane link 250 are disposed so as to be
inclined forwards and downwards. In discharge step P3, the
second driving link body 247 is disposed so as to face
D rearwards, and the second vane link 260 is disposed so as to
face rearwards and downwards.
Specifically, when discharge step P2 is switched to
discharge step P3, Li-Li' of the first vane link 250 is
further rotated in the discharge direction of air. When
D discharge step P2 is switched to discharge step P3, L2-L2'
of the second vane link 260 is further rotated in the
direction opposite the discharge direction of air. When
discharge step P2 is switched to discharge step P3, D-D' of
the first driving link body 246 is further rotated in the
discharge direction of air.
When discharge step P2 is switched to discharge step
P3, both the first vane 210 and the second vane 220 are
turned or rotated further vertically downwards on the basis
of the discharge port 102.
<Discharge step P4>
In discharge step P3, the driving link 240 may be
rotated in the second direction (in the counterclockwise
direction in the figures of this embodiment), which is
opposite the first direction, to provide discharge step P4.
In discharge step P4, the vane module 200 may provide
88264224.1 inclined wind that is discharged further downwards than in discharge step P3. In the state of the inclined wind of discharge step P4, air is discharged further downwards than in the state of the inclined wind of discharge step P3.
In discharge step P4, both the first vane 210 and the
second vane 220 are adjusted so as to face further downwards
than in discharge step P3.
In discharge step P4, the distance S4 between the

220 are disposed further vertically than in P3.
When discharge step P3 is switched to discharge step
P4, the front end 222a of the second vane 220 is moved

in discharge step P3.
When discharge step P3 is switched to discharge step
88264224.1
P4, the second vane 220 is rotated in place about the second
vane shaft 221. When discharge step P3 is switched to
discharge step P4, the first joint portion 216 of the first
vane 210 stays almost in place, and the second joint portion
217 is rotated about the first joint portion 216 in the
first direction (the clockwise direction).
That is, when discharge step P3 is switched to
discharge step P4, the first vane 210 is hardly moved, and
is rotated in place. When discharge step P3 is switched to
D discharge step P4, the first vane 210 is rotated about the
first joint portion 216 in the first direction (the
clockwise direction).
When discharge step P3 is switched to discharge step
P4, the second vane 220 is further rotated in the first
direction (the clockwise direction).
When discharge step P3 is switched to discharge step
P4, the front end 222a of the second vane 220 is further
rotated in the first direction (the clockwise direction) due
to downward movement of the second vane link 220.

in the same direction.
When discharge step P3 is switched to discharge step
P4, the 1-1 vane link shaft 251 may be located further
forwards than the 1-2 vane link shaft 252.
88264224.1
In discharge step P4, the vane motor 230 is rotated
100 degrees (P4 rotational angle), and the first vane 210
has an inclination of about 35 degrees (first vane P4
inclination) and the second vane 220 has an inclination of
about 70 degrees (second vane P4 inclination) by rotation of
the vane motor 230.
The positional relationship between the shafts forming
the centers of rotation of the respective links in discharge
step P4 will be described.
D In discharge step P4, the second joint portion 217 and
the first joint portion 216 of the first vane 210 are
disposed so as to be inclined forwards in the discharge
direction of air, similarly to P3.
When viewed from the side, the third joint portion 226
of the second vane 220 is disposed at the rearmost side, the
first joint portion 216 is disposed at the frontmost side,
and the second joint portion 217 is disposed between the
first joint portion 216 and the third joint portion 226.
In discharge step P4, the third joint portion 226 is
moved further downwards. In discharge step P4, the first
joint portion 216 of the first vane link 250 is slightly
moved upwards in the second direction (the counterclockwise
direction) or is located almost in place, and the second
joint portion 217 is rotated about the first joint portion
216 in the first direction (the clockwise direction).
88264224.1
When the first vane 210 is further rotated than in
discharge step P4, the first vane 210 is moved in the
direction opposite the advancing direction up to now. In
discharge step P1 to discharge step P4, the first vane 210
is moved in the discharge direction of air, and is rotated
about the second joint portion 217 in the first direction
(the clockwise direction).
In discharge step P4, the disposition of the shafts at
the driving link 240, the first vane link 250, and the
D second vane link 260 is similar to that in discharge step
P3. In discharge step P4, however, the second joint portion
217 and the first joint portion 216 are disposed in a line
in the longitudinal direction of the first driving link body
246.
Relative heights of the first driving link shaft 241,
the 1-1 vane link shaft 251, and the 2-1 vane link shaft 261
rotated by operation of the driving link 240, the first vane
link 250, and the second vane link 260 are varied.
In discharge step P4, the first driving link shaft 241
is moved upwards, and the 2-1 vane link shaft 261 is moved
downwards, whereby the first driving link shaft 241 is
located slightly higher than the 2-1 vane link shaft 261.
When discharge step P3 is switched to discharge step
P4, the second joint portion 217 is further rotated about
the core link shaft 243 toward the 1-2 vane link shaft 252,
88264224.1 and the core link shaft 243, the first driving link shaft
241, and the 1-1 vane link shaft 251, each of which is
formed in the shape of a straight line, may be disposed in a
line.
D In discharge step P4, the 2-2 vane link journal 262 is
located lower than the core link shaft 243.
When discharge step P3 is switched to discharge step
P4, the 2-1 vane link shaft 261 is moved further rearwards
than the 2-2 vane link journal 262.
D On the basis of the suction panel 320 or the discharge
port 102, the position of the first vane 210 and the second
vane 220 in discharge step P4 is similar to that in
discharge step P3.
Next, relative positions and directions of the
respective links in discharge step P4 will be described.
When discharge step P3 is switched to discharge step
P4, the first vane link 250 and the second vane link 260 are
disposed so as to face in opposite directions. When
discharge step P3 is switched to discharge step P4, the
first vane link 250 is hardly rotated, and only the second
vane link 260 may be rotated rearwards.
In this embodiment, there is no separate construction
capable of limiting motion of the first vane link 250. In
this embodiment, motion of the first vane link 250 may be
limited through the coupling relationship between the first
88264224.1 vane link 250, the first vane 210, and the first driving link body 246.
In discharge step P4, the first driving link body 246
and the first vane link 250 are disposed so as to be
inclined forwards and downwards. In discharge step P4, the
second driving link body 247 is disposed so as to face
rearwards, and the second vane link 260 is disposed so as to
face rearwards and downwards.
In this embodiment, when discharge step P3 is switched
D to discharge step P4, Li-Li' of the first vane link 250 may

In discharge step P4, D-D' and B-B' are connected to
each other as a straight line, and have an angle of 180
degrees therebetween.
D-D' and B-B' have an angle of less than 180 degrees
therebetween in discharge step P1 to discharge step P3, an
angle of less than 180 degrees therebetween in discharge
88264224.1 step P4, and an angle of greater than 180 degrees therebetween in discharge step P5 and discharge step P5.
<Discharge step P5>
In discharge step P4, the driving link 240 may be

direction in the figures of this embodiment), which is
opposite the first direction, to provide discharge step P5.
In discharge step P5, the vane module 200 may provide
inclined wind that is discharged further downwards than in
D discharge step P4. In the state of the inclined wind of
discharge step P5, air is discharged further downwards than
in the state of the inclined wind of discharge step P4.
In discharge step P5, both the first vane 210 and the
second vane 220 are adjusted so as to face further downwards
than in discharge step P4.
In discharge step P5, the distance S5 between the
front end 222a of the second vane 220 and the rear end 212b
of the first vane 210 is greater than the distance S4 in
discharge step P4.
When discharge step P4 is switched to P5, the distance

P5, the front end 222a of the second vane 220 is moved
further downwards, and the rear end 212b of the first vane
210 is moved further upwards.
In discharge step P5, the front end 222a of the second
vane 220 is located lower than in discharge step P4, and the
rear end 212b of the first vane 210 is located higher than
in discharge step P4.
When discharge step P4 is switched to discharge step
P5, the second vane 220 is rotated in place about the second
D vane shaft 221. When discharge step P4 is switched to
discharge step P5, the first joint portion 216 of the first
vane 210 stays almost in place, and the second joint portion
217 is further rotated about the first joint portion 216 in
the first direction (the clockwise direction).
That is, when discharge step P4 is switched to

is rotated in place about the first joint 216.
When discharge step P4 is switched to discharge step
P5, the first vane 210 is further rotated about the first
joint portion 216 in the first direction (the clockwise
direction). When discharge step P4 is switched to discharge
step P5, the second vane 220 is further rotated in the first

When discharge step P4 is switched to discharge step
P5, the front end 222a of the second vane 220 is further
88264224.1 rotated in the first direction (the clockwise direction) due to downward movement of the second vane link 220.
When discharge step P4 is switched to discharge step
P5, the first vane 210 and the second vane 220 are rotated
in the same direction.
When discharge step P4 is switched to discharge step
P5, the 1-1 vane link shaft 251 may be located further
forwards than the 1-2 vane link shaft 252.
In discharge step P5, the vane motor 230 is rotated
D 105 degrees (P5 rotational angle), and the first vane 210
has an inclination of about 44 degrees (first vane P5
inclination) and the second vane 220 has an inclination of
about 72 degrees (second vane P5 inclination) by rotation of
the vane motor 230.
D The positional relationship between the shafts forming
the centers of rotation of the respective links in discharge
step P5 will be described.
In discharge step P5, the second joint portion 217 and
the first joint portion 216 of the first vane 210 are
disposed so as to be inclined forwards in the discharge
direction of air, similarly to discharge step P4.
When viewed from the side, the third joint portion 226
of the second vane 220 is disposed at the rearmost side, the
first joint portion 216 is disposed at the frontmost side,
and the second joint portion 217 is disposed between the
88264224.1 first joint portion 216 and the third joint portion 226.
In discharge step P5, the third joint portion 226 is
moved further downwards, and the second joint portion 217 of
the first vane link 250 is rotated about the first joint
D portion 216 in the first direction (the clockwise
direction).
In discharge step P5, the second joint portion 217 is
located so as to protrude toward the 1-2 vane link shaft 252
on the basis of an imaginary straight line joining the core
D link shaft 243 and the first joint portion 216 to each
other.
In discharge step P5, the disposition of the shafts at
the driving link 240, the first vane link 250, and the
second vane link 260 is similar to that in discharge step
P4.
Relative heights of the first driving link shaft 241,
the 1-1 vane link shaft 251, and the 2-1 vane link shaft 261
rotated by operation of the driving link 240, the first vane
link 250, and the second vane link 260 are varied.
When discharge step P4 is switched to discharge step
P5, the first driving link shaft 241 is moved upwards, and
the 2-1 vane link shaft 261 is moved downwards. In
discharge step P5, therefore, the first driving link shaft
241 is located slightly higher than the 2-1 vane link shaft
261.
88264224.1
When discharge step P4 is switched to discharge step
P5, the second joint portion 217 is rotated about the core
link shaft 243, and the second joint portion 217 is further
rotated toward the 1-2 vane link shaft 252.
In discharge step P5, the core link shaft 243, the
first driving link shaft 241, and the 1-1 vane link shaft
251 are disposed in a line. In discharge step P5, the core
link shaft 243, the first driving link shaft 241, and the 1
1 vane link shaft 251 form an obtuse angle of 180 degrees or
D more (on the basis of D-D').
In discharge step P5, the 2-2 vane link journal 262 is
located lower than the core link shaft 243. When discharge
step P1 is switched to discharge step P6, the angle formed
by the core link shaft 243, the 2-2 vane link journal 262,
D and the third joint portion 226 gradually increases.
When discharge step P1 is switched to discharge step
P6, however, the angle formed by the core link shaft 243,
the 2-2 vane link journal 262, and the third joint portion
226 is less than 180 degrees.
When discharge step P4 is switched to discharge step
P5, the 2-1 vane link shaft 261 is moved further rearwards
than the 2-2 vane link journal 262, and is located between
the third joint portion 226 and the core link shaft 243.
On the basis of the suction panel 320 or the discharge
port 102, the position of the first vane 210 and the second
88264224.1 vane 220 in discharge step P5 is similar to that in discharge step P4.
Next, relative positions and directions of the
respective links in discharge step P5 will be described.
When discharge step P4 is switched to discharge step
P5, the first vane link 250 and the second vane link 260 are
disposed so as to face in opposite directions. When
discharge step P4 is switched to discharge step P5, the
first vane link 250 is hardly rotated, and only the second
D vane link 260 may be further rotated rearwards.
In discharge step P5, the disposition of the first
driving link body 246, the first vane link 250, the second
vane link 260 is similar to that in discharge step P4.
In this embodiment, when discharge step P4 is switched

be rotated in the direction opposite the discharge direction
of air. When discharge step P4 is switched to discharge
step P5, L2-L2' of the second vane link 260 is further
rotated in the direction opposite the discharge direction of
air. When discharge step P4 is switched to discharge step
P5, D-D' of the first driving link body 246 is rotated in
the discharge direction of air.
In discharge step P5, D-D' and B-B' have an obtuse
angle therebetween.
When discharge step P1 is switched to discharge step
88264224.1
P4, the front end 212a of the first vane is moved in the
discharge direction of air (forwards). When discharge step
P4 is switched to discharge step P6, however, the front end
212a of the first vane is moved in the direction opposite
the discharge direction of air (rearwards).
When discharge step P4 is switched to discharge step
P6, therefore, the first vane 210 may be disposed further
vertically.
<Discharge step P6>
D In this embodiment, the state of the module vane 200
in discharge step P6 is defined as vertical wind.
The vertical wind does not mean that the first vane
210 and the second vane 220 constituting the module vane 200
are disposed vertically. This means that air discharged
from the discharge port 102 is discharged downwards from the
discharge port 102.
In discharge step P5, the driving link 240 may be
rotated in the second direction (in the counterclockwise
direction in the figures of this embodiment), which is
opposite the first direction, to provide discharge step P6.
In discharge step P6, the flow of the discharged air in the
horizontal direction is minimized, and the flow of the
discharged air in the vertical direction is maximized. In
the state of the vertical wind of discharge step P6 air is
discharged further downwards than in the state of the
88264224.1 inclined wind of discharge step P5.
In discharge step P6, both the first vane 210 and the
second vane 220 are adjusted so as to face further downwards
than in discharge step P5.
In discharge step P6, the distance S6 between the
front end 222a of the second vane 220 and the rear end 212b
of the first vane 210 is greater than the distance S5 in
discharge step P5.
When discharge step P5 is switched to P6, the distance
D between the front end 222a of the second vane 220 and the
rear end 212b of the first vane 210 further increases. In
discharge step P6, the first vane 210 and the second vane
220 are disposed further vertically than in P5.
When discharge step P5 is switched to discharge step
D P6, the front end 222a of the second vane 220 is moved
further downwards, and the rear end 212b of the first vane
210 is moved further upwards.
In discharge step P6, the front end 222a of the second
vane 220 is located lower than in discharge step P5, and the
rear end 212b of the first vane 210 is located higher than
in discharge step P5.
When discharge step P5 is switched to discharge step
P6, the second vane 220 is rotated in place about the second
vane shaft 221. When discharge step P5 is switched to
discharge step P6, the first joint portion 216 of the first
88264224.1 vane 210 stays almost in place, and the second joint portion
217 is further rotated about the first joint portion 216 in
the first direction (the clockwise direction).
That is, when discharge step P5 is switched to
discharge step P6, the first vane 210 may be moved
rearwards. When discharge step P5 is switched to discharge
step P6, the front end 212a of the first vane 210 is moved
rearwards, since the first vane 210 is further rotated about
the first joint portion 216 in the first direction (the
D clockwise direction).
When discharge step P5 is switched to discharge step
P6, the second vane 220 is further rotated in the first
direction (the clockwise direction). When discharge step P5
is switched to discharge step P6, the front end 222a of the
D second vane 220 is further rotated in the first direction
(the clockwise direction) due to downward movement of the
second vane link 220.
When discharge step P5 is switched to discharge step
P6, the first vane 210 and the second vane 220 are rotated
in the same direction.
In discharge step P6, the vane motor 230 is rotated
110 degrees (P5 rotational angle), and the first vane 210
has an inclination of about 56 degrees (first vane P6
inclination) and the second vane 220 has an inclination of
about 74 degrees (second vane P6 inclination) by rotation of
88264224.1 the vane motor 230.
The positional relationship between the shafts forming
the centers of rotation of the respective links in discharge
step P6 will be described.
In discharge step P6, the second joint portion 217 and
the first joint portion 216 of the first vane 210 are
disposed so as to be inclined forwards in the discharge
direction of air, similarly to discharge step P5.
When viewed from the side, the third joint portion 226
D of the second vane 220 is disposed at the rearmost side, the
first joint portion 216 is disposed at the frontmost side,
and the second joint portion 217 is disposed between the
first joint portion 216 and the third joint portion 226.
In discharge step P6, the third joint portion 226 is
D moved further downwards, and the second joint portion 217 of
the first vane link 250 is rotated about the first joint
portion 216 in the first direction (the clockwise
direction).
In discharge step P6, the second joint portion 217 is
located so as to further protrude toward the 1-2 vane link
shaft 252 on the basis of an imaginary straight line joining
the core link shaft 243 and the first joint portion 216 to
each other.
In discharge step P6, the disposition of the shafts at
the driving link 240, the first vane link 250, and the
88264224.1 second vane link 260 is similar to that in discharge step
P5.
Relative heights of the first driving link shaft 241,
the 1-1 vane link shaft 251, and the 2-1 vane link shaft 261
rotated by operation of the driving link 240, the first vane
link 250, and the second vane link 260 are varied.
When discharge step P5 is switched to discharge step
P6, the first driving link shaft 241 is moved upwards, and
the 2-1 vane link shaft 261 is moved downwards. In
D discharge step P6, therefore, the first driving link shaft
241 is located higher than the 2-1 vane link shaft 261.
When discharge step P5 is switched to discharge step
P6, the second joint portion 217 is rotated about the core
link shaft 243, and the second joint portion 217 is further
rotated toward the 1-2 vane link shaft 252.
When viewed from the side, in discharge step P6, at
least a portion of the second joint portion 217 may overlap
the first vane link body 255. Since the second joint
portion 217 is moved to the position at which the second
joint portion overlaps the first vane link body 255, it is
possible to further vertically dispose the first vane 210.
In discharge step P6, however, the second joint
portion 217 is not moved forwards over Li-Li'. The second
joint portion 217 is not moved further forwards than the
first vane link body 255. In the case in which the second
88264224.1 joint portion 217 is excessively moved forwards, the second joint portion may not return to the original position thereof even when the vane motor is rotated in the first direction (the clockwise direction).
D In order to prevent excessive rotation of the driving
link 240, the first driving link body 246 and one end 270a
of the stopper 270 interfere with each other in discharge
step P6. The first driving link body 246 is supported by
the stopper 270, whereby further rotation of the driving
D link is limited.
In discharge step P6, the core link shaft 243, the
first driving link shaft 241, and the 1-1 vane link shaft
251 form an obtuse angle of 180 degrees or more (on the
basis of D-D').
D When discharge step P5 is switched to discharge step
P6, the 1-1 vane link shaft 251 may be located further
forwards than the 1-2 vane link shaft 252.
In discharge step P6, the 2-2 vane link journal 262 is
located at the lower side of the core link shaft 243, the
second joint portion 217 is located at the lower side of the
2-2 vane link journal 262, the third joint portion 226 is
located at the lower side of the second joint portion 217,
and the first joint portion 216 is located at the lower side
of the third joint portion 226.
When discharge step P5 is switched to discharge step
88264224.1
P6, the 2-1 vane link shaft 261 is moved further rearwards
than the 2-2 vane link journal 262, and is located between
the third joint portion 226 and the core link shaft 243.
Next, relative positions and directions of the
respective links in discharge step P6 will be described.
When discharge step P5 is switched to discharge step
P6, the first vane link 250 and the second vane link 260 are
disposed so as to face in opposite directions. When
discharge step P5 is switched to discharge step P6, the
D first vane link 250 is hardly rotated, and only the second
vane link 260 may be further rotated rearwards.
In discharge step P6, the disposition of the first
driving link body 246, the first vane link 250, the second
vane link 260 is similar to that in discharge step P5.
D In this embodiment, when discharge step P5 is switched
to discharge step P6, Li-Li' of the first vane link 250 may
be further rotated in the direction opposite the discharge
direction of air. When discharge step P5 is switched to
discharge step P6, L2-L2' of the second vane link 260 is
further rotated in the direction opposite the discharge
direction of air. When discharge step P5 is switched to
discharge step P6, D-D' of the first driving link body 246
is further rotated in the direction opposite the discharge
direction of air.
In discharge step P6, the angle between D-D' and B-B',
88264224.1 which is an obtuse angle, is greater than the angle between
D-D' and B-B', which is an obtuse angle, in discharge step
P5.
When discharge step P1 is switched to discharge step
P4, the front end 212a of the first vane is moved in the
discharge direction of air (forwards).
When discharge step P1 is switched to discharge step
P4, the first vane link 250 is rotated in the second
direction (the counterclockwise direction). When discharge
D step P4 is switched to discharge step P6, however, the first
vane link 250 is rotated in the first direction (the
clockwise direction).
When discharge step P1 is switched to discharge step
P4, therefore, the front end 212s of the first vane is
D rotated in the second direction and is moved upwards. When
discharge step P4 is switched to discharge step P6, however,
the front end 212s of the first vane is rotated in the first
direction and is moved downwards. That is, motion of the
first vane 210 is changed on the basis of discharge step P4.
When discharge step P4 is switched to discharge step
P6, the first vane 210 may be disposed further vertically.
In discharge step P6, the rear end 212b of the first vane
210 is located further forwards than the core link shaft
243.
When the vane module 200 forms the vertical wind in
88264224.1 the discharge step P6, the first vane 210 and the second vane 220 are maximally spaced apart from each other.
In discharge step P6, at least one of the second joint
portion 217 or the first drive link shaft 241 overlaps the
first vane link 250, when viewed from the side of the vane
module 200.
In discharge step P6, at least one of the second joint
portion 217 or the first drive link shaft 241 is located on
or behind Li-Li of the first vane link 250, when viewed from
D the side of the vane module 200.
In discharge step P6, the rear end 212b of the first
vane 210 is located inside the discharge port 102 and is
located higher than the outer surface of the side cover 314,
when viewed from the side of the vane module 200. Since the
rear end 212b of the first vane 210 is located inside the
discharge port 102, it is possible to guide air discharged
from the discharge port 102 in the vertical direction.
<Correlation between links constituting vane module
and centers of rotation thereof>
The relative lengths of the links and the centers of
rotation of the links must be appropriately disposed in
order to simultaneously control the first vane 210 and the
second vane 220 using only driving force provided to the
driving link 240. In the case in which a motor that
controls the first vane and a motor that controls the second
88264224.1 vane are separately provided, the relative position as in the present disclosure is not necessary.
In the present disclosure, the following conditions
are necessary to simultaneously control two vanes 210 and
220 using a single driving link 240. Particularly, in the

rotated in place, the structure as in the present disclosure
is not necessary.
In this embodiment, the first vane 210 is moved along
D a predetermined orbit while being rotated, and the second
vane 220 is rotated in place. Since the first vane and the
second vane are operated in different modes, as described
above, the following disposition is necessary.

link shaft 251 and the axial center of the 1-2 vane link
shaft 252 is defined as Al, and the distance between the 2-1
vane link shaft 261 and the axial center of the 2-2 vane
link journal 262 is defined as A2.
The distance Cl between the core link shaft 243 and
the first driving link shaft 241 is greater than the
88264224.1 distance C2 between the core link shaft 243 and the second driving link shaft 242 and is less than the distance Al between the 1-1 vane link shaft 251 and the 1-2 vane link shaft 252.
D The distance A2 between the 2-1 vane link shaft 261
and the 2-2 vane link journal 262 is greater than the
distance C2 between the core link shaft 243 and the second
driving link shaft 242 and is less than the distance Cl
between the core link shaft 243 and the first driving link
D shaft 241.
The distance Cl between the core link shaft 243 and
the first driving link shaft 241 is greater than the
distance C2 between the core link shaft 243 and the second
driving link shaft 242 and is less than the distance Cl
between the core link shaft 243 and the first driving link
shaft 241.
The distance between the driving link coupling portion
407 and the first vane link coupling portion 408 is defined
as R1, the distance between the driving link coupling
portion 407 and the second vane coupling portion 409 is
defined as R2, and the distance between the first joint
portion 216 and the second joint portion 217 is defined as
Bl.
The distance R1 between the driving link coupling
portion 407 and the first vane link coupling portion 408 is
88264224.1 less than the distance R2 between the driving link coupling portion 407 and the second vane coupling portion 409.
The distance B1 between the first joint portion 216
and the second joint portion 217 is less than the distance
Ri between the driving link coupling portion 407 and the
first vane link coupling portion 408.
The distance Al between the 1-1 vane link shaft 251
and the 1-2 vane link shaft 252 is greater than the distance
R1 between the driving link coupling portion 407 and the
D first vane link coupling portion 408.
