indoor unit of an air conditioner, and more particularly a
ceiling type indoor unit installed at the ceiling of a room.
[Background]
In general, an air conditioner includes a compressor,
D a condenser, an evaporator, and an expander, and supplies
cool air or hot air to a building or a room using an air
conditioning cycle.
Based on the structure thereof, the air conditioner is
classified as a separable air conditioner configured such
that a compressor is disposed outdoors or an integrated air
conditioner configured such that a compressor is integrally
manufactured.
In the separable air conditioner, an indoor heat
exchanger is installed in an indoor unit, an outdoor heat
exchanger and a compressor are installed in an outdoor unit,
and the two separated units are connected to each other via
a refrigerant pipe.
In the integrated air conditioner, an indoor heat
exchanger, an outdoor heat exchanger, and a compressor are
installed in a single case. Examples of the integrated air
88262457.1 conditioner include a window type air conditioner installed at a window and a duct type air conditioner installed outside a room in the state in which a suction duct and a discharge duct are connected to each other.
D The separable air conditioner is generally classified
depending on the form in which the indoor unit is installed.
An air conditioner configured such that an indoor unit
is vertically installed in a room is called a stand type air
conditioner, an air conditioner configured such that an
] indoor unit is installed at the wall of a room is called a
wall mounted air conditioner, and an air conditioner
configured such that an indoor unit is installed at the
ceiling of a room is called a ceiling type air conditioner.
In addition, there is a system air conditioner capable
of providing air-conditioned air to a plurality of spaces as
a kind of separable air conditioner.
The system air conditioner is classified as a type of
air conditioner including a plurality of indoor units in
order to air-condition rooms or a type of air conditioner
capable of supplying air-conditioned air to respective
spaces through ducts.
The plurality of indoor units provided in the system
air conditioner may be stand type indoor units, wall mounted

Consequently, the first module body 410 and the second
module body 420 are disposed at the lower side of the front
body 310. In the state in which the indoor unit is
installed, the direction in which the first module body 410
D and the corner frame 313 are fastened to each other is
disposed so as to be directed from the lower side to the
upper side, and the direction in which the second module
body 420 and the corner frame 313 are fastened to each other
is also disposed so as to be directed from the lower side to
D the upper side.
In the above structure, the entirety of the vane
module 200 may be easily separated from the front body 310
during repair.
The vane module 200 includes a first module body 410
disposed at one side of the discharge port 102, the first
module body being located at the lower side of the front
body 310, the first module body being assembled to the front
body 310 so as to be separable downwards therefrom, a second
module body 420 disposed at the other side of the discharge
port 102, the second module body being located at the lower
side of the front body 310, the second module body being
assembled to the front body 310 so as to be separable
downwards therefrom, at least one vane 210 and 220 having
one side and the other side coupled to the first module body
410 and the second module body 420, respectively, the vane
88262457.1 being configured to be rotated relative to the first module body 410 and the second module body 420, a vane motor 230 installed at at least one of the first module body 410 or the second module body 420, the vane motor being configured to provide driving force to the vane, a first fastening hole
403-1 disposed at the first module body 410, the first
fastening hole being disposed so as to face downwards, the
first fastening hole being formed through the first module
body 410, a first fastening member 401-1 fastened to the
] front body 310 through the first fastening hole 403-1, a
second fastening hole 403-2 disposed at the second module
body 420, the second fastening hole being disposed so as to
face downwards, the second fastening hole being formed
through the second module body 420, and a second fastening
member 401-2 fastened to the front body through the second
fastening hole 403-2.
In particular, since the first module body 410 and the
second module body 420 are located at the lower side of the
front body 310, only the main module 200 may be separated
from the front body 310 in the state in which the front body
310 is installed at the case housing 110. This is commonly
applied to all of the four vane modules 200.
In the case in which the module body 400 is separated
from the front body 310, the entirety of the vane module 200
is separated downwards from the front body 310.
88262457.1
The first module body 410 includes a module body
portion 402 coupled to the front body 310 and a link
installation portion 404 protruding upwards from the module
body portion 402.
D In this embodiment, the module body portion 402 is
securely fastened to the front body 310 in order to minimize
generation of vibration or noise due to the first vane 210,
the second vane 220, the vane motor 230, the driving link
240, the first vane link 250, and the second vane link 260.
] 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.
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
88262457.1 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 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,
specifically the front body 310. Specifically, the module
hook 405 and the front body 310 are caught by each other.
A plurality of module hooks 405 may be disposed at one
module body. In this embodiment, module hooks are disposed
at the outer edge and the front edge of the module body
portion 402. That is, module hooks 405 are disposed outside
the first module body 410 and the second module body 420,
and the module hooks 405 are symmetrical with each other in
the leftward-rightward direction.
The vane module 200 may be temporarily fixed to the
frame body 310 by the module hook 405 of the first module
body 410 and the module hook 405 of the second module body
88262457.1
420.
In the case of fixing using the module hooks 405, a
slight gap may be generated due to the coupling structure
thereof. The fastening member 401 securely fixes the
D temporarily fixed module body 400 to the front body 310.
The fastening hole 403, in which the fastening member
401 is installed, may be located between the module hooks
405. The fastening hole 403 of the first module body 410
and the fastening hole 403 of the second module body 420 are
] disposed between one module hook 405 and the other module
hook 405.
In this embodiment, the module hooks 405 and the
fastening holes 403 are disposed in a line.
Even when the fastening members 401 are removed, the
D 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
88262457.1 convenience at the time of repair.
The module body portion 402 is disposed horizontally,
and the link installation portion 404 is disposed
vertically. In particular, the link installation portion
404 protrudes upwards from the module body portion 402 in
the state of being installed.
The link installation portion 404 of the first module
body 410 and the link installation portion 404 of the second
module body 420 are disposed so as to face each other. The
] first vane 210, the second vane 220, the driving link 240,
the first vane link 250, and the second vane link 260 are
installed between the link installation portion 404 of the
first module body 410 and the link installation portion 404
of the second module body 420. The vane motor 230 is
disposed outside the link installation portion 404 of the
first module body 410 or the link installation portion 404
of the second module body 420.
The vane motor 230 may be installed at only one of the
first module body 410 and the second module body 420. In
this embodiment, the vane motor 230 may be installed at each
of the first module body 410 and the second module body 420.
The first vane 210, the second vane 220, the driving
link 240, the first vane link 250, and the second vane link
260 are coupled between the first module body 410 and the
second module body 420, whereby the vane module 200 is
88262457.1 integrated.
In order to install the vane motor 230, a vane motor
installation portion 406 protruding outside the link
installation portion 404 is disposed. The vane motor 230 is
fixed to the vane motor installation portion 406 by
fastening. The vane motor installation portion 406 is
formed in the shape of a boss, and the vane motor 230 is
fixed to the vane motor installation portion 406. By the
provision of the vane motor installation portion 406, the
D link installation portion 404 and the vane motor 230 are
spaced apart from each other by a predetermined distance.

driving link 240 is assembled and which provides the center
of rotation to the driving link 240, a first vane link
D coupling portion 408 to which the first vane link 250 is
assembled and which provides the center of rotation to the
first vane link 250, and a second vane coupling portion 409
which is coupled with the second vane 220 and which provides
the center of rotation to the second vane 220 are disposed
at the link installation portion 404.
In this embodiment, each of the driving link coupling
portion 407, the first vane link coupling portion 408, and
the second vane coupling portion 409 is formed in the shape
of a hole. Unlike this embodiment, the same may be formed
in the shape of a boss, or may be realized as any of various
88262457.1 forms that provide a rotary shaft.
Meanwhile, a stopper 270 configured to limit the
rotational angle of the driving link 240 is disposed at the
link installation portion 404. The stopper 270 is disposed
D so as to protrude toward the opposite link installation
portion 404.
In this embodiment, the stopper 270 interferes with
the driving link 240 at a specific position at the time of
rotation thereof, and limits rotation of the driving link
] 240. The stopper 270 is located within the radius of
rotation of the driving link 240.
In this embodiment, the stopper 270 is manufactured
integrally with the link installation portion 404. In this
embodiment, the stopper 270 defines the installation
D position of the driving link 240, remains in contact with
the driving link 240 at the time of rotation thereof, and
inhibits vibration or free movement of the driving link 240.
In this embodiment, the stopper 270 is formed in the
shape of an arc.
<Construction of driving link>
The driving link 240 is directly connected to the vane
motor 230. A motor shaft (not shown) of the vane motor 230
is directly coupled to the driving link 240, and the
rotation amount of the driving link 240 is determined based
on the rotational angle of the rotary shaft of the vane
88262457.1 motor 230.
The driving link 240 is assembled to the vane motor
230 through the link installation portion 404. In this
embodiment, the driving link 240 extends through the driving

link shaft 242 may be manufactured integrally with the
second vane link 260.
In this embodiment, the second driving link shaft 242
is disposed at the second driving link body 247. The second
88262457.1 driving link shaft 242 is disposed opposite the first driving link shaft 241 on the basis of the core link shaft
243.
An imaginary straight line joining the first driving
link shaft 241 and the core link shaft 243 to each other and
an imaginary straight line joining the core link shaft 243
and the second driving link shaft 242 to each other have a
predetermined angle E therebetween. The angle E is greater
than 0 degrees and less than 180 degrees.
] <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, a 1-1 vane link shaft 251 disposed at the first
vane link body 255, the 1-1 vane link shaft being assembled
to the first vane 210, the 1-1 vane link shaft being
configured to be rotated relative to the first vane 210, and
a 1-2 vane link shaft 252 disposed at 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 rotated
relative to the module body 400.
The 1-1 vane link shaft 251 protrudes toward the first
88262457.1 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
rotated relative to 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.
D The second vane link 260 includes a second vane link
body 265, a 2-1 vane link shaft 261 disposed at the second
vane link body 265, the 2-1 vane link shaft being assembled

rotated relative to the driving link 240.
In this embodiment, the 2-2 vane link journal 262 is
88262457.1 formed in the shape of a hole formed through the second vane link body 265. Since the 2-2 vane link journal 262 and the second driving link shaft 242 have relative structures, one is formed in the shape of a shaft and the other is formed in the shape of a hole having the center of rotation. Unlike this embodiment, therefore, the 2-2 vane link journal 262 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
] 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.
<Construction of vane>
D 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.
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
88262457.1 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.
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
D 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
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.
88262457.1
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
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

the discharge port 102 and a joint rib 214 protruding
D 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 may be formed so as to have a
gently curved surface.
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
surface of the first vane body 212, whereby the flow
direction thereof may be guided.
The flow direction of the discharged air and the
longitudinal direction of the first vane body 212 are
88262457.1 perpendicular to each other or intersect each other.
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
D 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
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.
88262457.1
In this embodiment, each of the first joint portion
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
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.
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
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
88262457.1
214 and the link installation portion 404.
In this 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.
<Construction of second vane>
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 224 being
coupled to the second vane link 260 so as to be rotatable
relative thereto, and a second vane shaft 221 formed at the
second vane body 222, the second vane shaft being rotatably
coupled to the link installation portion 404.
The joint rib 224 is a structure in which axial
coupling or hinge coupling is possible, and may be changed
into any of various forms. A hole formed in the second
joint rib 224 and coupled to the second vane link 220 so as
to be rotatable relative thereto is defined as a third joint
portion 226.
In this embodiment, the third joint portion 226 is
formed in the shape of a hole, and is formed through the
joint rib 224. The third joint portion 226 is a structure
in which axial coupling or hinge coupling is possible, and
may be changed into any of various forms.
88262457.1
In the case in which it is necessary to distinguish
between the joint rib 214 of the first vane and the joint
rib 224 of the second vane, the joint rib of the first vane
is defined as a first joint rib 214, and the joint rib of
the second vane is defined as a second joint rib 224.
The second vane 220 may be rotated about the second
joint rib 224, and may also be rotated about the second vane
shaft 221. That is, the second vane 220 may be rotated
relative to each of the second joint rib 224 and the second
D vane shaft 221.
When viewed in a top view, the second joint rib 224 is
located further forwards than the second vane shaft 221.
The second joint rib 224 is moved along a predetermined
orbit about the second vane shaft 221.
D The second vane body 222 may be formed so as to be
gently curved.
The second vane body 222 controls the direction of air
that is discharged along the discharge channel 104. The
discharged air collides with the upper surface or the lower
surface of the second vane body 222, whereby the flow
direction thereof is guided.
The flow direction of the discharged air and the
longitudinal direction of the second vane body 222 are
perpendicular to each other or intersect each other.
When viewed in a top view, at least a portion of the
88262457.1 second vane body 222 may be located between the first joint portions 212 of the first vane 210.
This is necessary to prevent interference when the
second vane 220 is located at the upper side of the first
vane 210. The front end of the second vane body 222 is
located between the first joint portions 214. That is, the
front length of the second vane body 222 is less than the
length between the first joint portions 214.
The second joint rib 224 is an installation structure
] for assembly with the second vane link 260. The second
joint rib 224 is disposed at each of one side and the other
side of the second vane body 222.
The second joint rib 224 is coupled to the second vane

<Disposition of vane module and suction grill>
The coupling structure and the separation structure of
the vane module will be described in more detail with
reference to FIGS. 1 to 4 and 15 to 17.
When the suction grill 320 is separated in the state
of FIG. 1, four vane modules 200 are exposed, as shown in
FIG. 15. The suction grill 320 is separably assembled to
the front body 310.
88262457.1
The suction grill 320 may be separated from the front
body 310 using various methods.
The suction grill 320 may be separated using a method
of separating and rotating one edge of the suction grill on
the basis of the other edge of the suction grill. In
another method, the suction grill 320 may be separated from
the front body 310 through release of catching in the state
of being caught by the front body. In a further method,
coupling between the suction grill 200 and the front body
D 310 may be maintained by magnetic force.
In this embodiment, the suction grill 320 may be moved
in the upward-downward direction by an elevator 500
installed at the front body 310. The elevator 500 is
connected to the suction grill 320 via a wire (not shown).
The wire may be wound or unwound by operation of the
elevator 500, whereby the suction grill 320 may be moved
downwards or upwards.
A plurality of elevators 500 is disposed, and the
elevators 500 simultaneously move opposite sides of the
suction grill 320.
When the suction grill 320 is moved downwards, the
first module body 410 and the second module body 420, hidden
by the suction grill 320, are exposed.
In the state in which the suction grill 320 is
assembled to the front body 310, at least one of the first
88262457.1 vane 210 or the second vane 220 of the vane module 200 may be exposed.
When the indoor unit is not operated, only the first
vane 210 is exposed to the user. When the indoor unit is
D operated and air is discharged, the second vane 220 may be
selectively exposed to the user.
In the state in which the suction grill 320 is
assembled to the front body 310, the first module body 410
and the second module body 420 of the vane module 200 are
] hidden by the suction grill 320.
Since the fastening holes 403 are disposed at the
first module body 410 and the second module body 420, the
fastening holes 403 are hidden by the suction grill 320 so
as not to be visible to the user.
Since the first module body 410 and the second module
body 420 are located at the upper side of the grill corner
portion 327 constituting the suction grill 320, the grill
corner portion 327 prevents the first module body 410 and
the second module body 420 from being exposed outside.
The grill corner portion 327 also prevents the
fastening holes 403 formed in the first module body 410 and
the second module body 420 from being exposed outside.
Since the grill corner portion 327 is located at the lower
side of the fastening holes 403, the fastening holes 403 are
hidden by the grill corner portion 327.

and the second module bodies 420 so as not to be exposed.
That is, in the case in which the suction grill 320 is in
tight contact with the front body 310, the first module
bodies 410 and the second module bodies 420 are hidden by
the suction grill 320 and thus are not exposed to the user.
Since the first module bodies 410 and the second

thereof correspond to each other.
In the same manner, the grill corner border 326
defining the edge of the grill corner portion 327 is
disposed so as to face the inner edge of the first vane 210,
and the curved shapes thereof correspond to each other.
Meanwhile, in this embodiment, a permanent magnet 318
and a magnetic force fixing portion 328 are disposed in
order to maintain the state in which the suction grill 320
is in tight contact with the front body 310.
88262457.1
One of the permanent magnet 318 and the magnetic force
fixing portion 328 may be disposed at the front body 310,
and the other of the magnetic force fixing portion 328 and
the permanent magnet 318 may be disposed at the upper
D surface of each grill corner portion 327.
The permanent magnet 318 and the magnetic force fixing
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
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.
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
through interaction with the permanent magnet 318. The
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.
88262457.1
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
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

D module body 410 of the first vane module 201 and the second
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
portion 328 are located at the upper side of each grill
corner portion 327, and are hidden by each grill corner
portion 327.

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 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
88262457.1 the vane module 200 is not operated is defined as a stop step PG.
<Stop step PO>
In stop step PO, the vane module 200 is not operated.
When the indoor unit is not operated, the vane module 200 is

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
D covers the discharge port 102, and prevents parts
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
88262457.1 the centers of rotation of the respective links in stop step

located at the upper side of the second joint portion 217
D 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
D and the first joint portion 216.
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

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 PO, 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
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
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
vane 210 and the second vane 220 may form a continuous
88262457.1 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.
When the vane module 200 provides discharge step P1,
which is one of the plurality of discharge steps, 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 higher than the rear end 212a of the first vane 210.
The upper surface of the second vane 220 is located
D higher than the upper surface of the first vane 210.
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.
The rear end 222b of the second vane 220 is located
higher than the discharge port 102, the front end 222a of
the second vane is located lower than the discharge port
102, and the rear end 212b of the first vane is located
lower than the front end 222a of the second vane.
In discharge step P1, the front end 222a of the second
88262457.1 vane 220 is located higher than the rear end 212b of the first vane 210.
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
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
D 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 may be
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
88262457.1 the side.
In discharge step P1, the second vane 220 is rotated
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
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
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
88262457.1 discharge step P1, the driving link 240 is rotated in the counterclockwise direction, the first vane line 210 is 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
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
D downward movement of the second vane link 220.
When stop step PO is switched to discharge step P1 in
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)
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,
88262457.1 unlike PO. 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.
The 2-1 vane link shaft 261 is located lower than the
second vane shaft 221, the first driving link shaft 241 is
located lower than the 2-1 vane link shaft 261, and the 1-1
] vane link shaft 251 is located lower than the first driving
link shaft 241.
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. When providing
discharge step P1, the second vane shaft 221, the 2-1 vane
link shaft 261, the first driving link shaft 241, and the 1
1 vane link shaft 251 are disposed in a line.
In some embodiments, the third joint portion 226, the
second joint 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.
In this case, the second vane shaft 221 is located at the
88262457.1 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
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
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
88262457.1 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
D 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.
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. When
providing discharge step P1, the first driving link shaft
241 and the 1-1 vane link shaft 251 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
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
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
88262457.1 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.
D 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
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.
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.
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
88262457.1 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
of this embodiment), which is opposite the first direction,
to provide discharge step P2.
When the vane module provides one of discharge steps
P2 to P5, the rear end 212b of the first vane is located
higher than the front end 222a of the second vane and is
located level with or lower than the 2-1 vane link shaft
261.
In addition, when the vane module provides one of
discharge steps P2 to P5, the angle formed by the core link
shaft 243, the first driving link shaft 241, and the 1-1
vane link shaft 251 in the clockwise direction with respect
to an imaginary straight line D-D' joining the core link
88262457.1 shaft 243 and the first driving link shaft 241 to each other is an acute angle.
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
] 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.
88262457.1
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
] 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
88262457.1 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
88262457.1 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
] 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
88262457.1
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
] 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
88262457.1 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.
88262457.1
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.
] 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
88262457.1 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
] 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
88262457.1 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
88262457.1 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.
] 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.
88262457.1
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
] 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

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

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

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
] more (on the basis of D-D').
In discharge step P5, the 2-2 vane link journal 262 is

On the basis of the suction panel 320 or the discharge
port 102, the position of the first vane 210 and the second
88262457.1 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

88262457.1
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
88262457.1 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.
When providing discharge step P6, the rear end 222b of
the second vane is located higher than the discharge port,
the front end 222a of the second vane is located lower than
the discharge port, and the rear end 212b of the first vane
is located higher than the front end 222a of the second vane
] and is located higher than the discharge port. In addition,
the front end 212a of the first vane is located lower than

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
88262457.1
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
D vane shaft 221. When discharge step P5 is switched to
discharge step P6, 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 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
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
88262457.1 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
D 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
D inclination) and the second vane 220 has an inclination of
about 74 degrees (second vane P6 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
D 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
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
88262457.1 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
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 providing discharge step P6, the rear end 212b of
the first vane is located at the lower side of the core link
shaft 243, and is located further forwards than the core
link shaft 243. When providing discharge step P6, the front
end 212a of the first vane is located further rearwards than
the front edge 102a of the discharge port.
When discharge step P5 is switched to discharge step
P6, the first driving link shaft 241 is moved upwards, and
88262457.1 the 2-1 vane link shaft 261 is moved downwards. In discharge step P6, therefore, the first driving link shaft
241 is located higher than the 2-1 vane link shaft 261.
When providing discharge step P6, the 2-2 vane link
journal 262 is located lower than the core link shaft 243,
the first driving link shaft 241 is located lower than the
2-2 vane link journal 262, the 2-1 vane link shaft 261 is
located lower than the first driving link shaft 241, and the
1-1 vane link shaft 251 is located lower than the 2-1 vane
D 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
joint portion 217 is excessively moved forwards, the second
88262457.1 joint portion may not return to the original position thereof even when the vane motor is rotated in the first direction (the clockwise direction).
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
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 (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
P6, the 2-1 vane link shaft 261 is moved further rearwards
88262457.1 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.
D 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
first vane link 250 is hardly rotated, and only the second
D 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.
When providing discharge step P6, the 2-1 vane link
shaft 261 is located further forwards than the second vane
shaft 221, the 2-2 vane link journal 262 is located further
forwards than the 2-1 vane link shaft 261, the core link
shaft 243 is located further forwards than the 2-2 vane link
journal 262, the first driving link shaft 241 is located
further forwards than the core link shaft 243, and the 1-1
vane link shaft 251 is located further forwards than the
first driving link shaft 241.
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
88262457.1 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.
