Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an air conditioner, and
more particularly, to a structure of a discharge grill for an
indoor unit of an air conditioner for increasing a durability of a
link and stably operating a discharge grill.
[0003] 2. Description of the Related Art
[0004] An air conditioner is a device for maintaining optimized
inside air according to purpose. For example, in the case where
inside air becomes high temperature in summer, the air conditioner
blows wind of low temperature to cool down the inside. On the
contrary, in winter, the air conditioner blows warm wind of high
temperature to heat the inside air.
[0005] The air conditioners are roughly divided into an integral
type and a separation type. An integral type air conditioner has
one unit as a whole and a separation type air conditioner
separately has an indoor unit installed inside a space that needs
air-conditioning and an outdoor unit installed in the outside.
Particularly, recently, a separation type air conditioner is widely
used considering noise and installation environment of an air
conditioner.
[0006] FIG. 1 is an exploded perspective view of a separation type
air conditioner of a related art and FIG. 2 is an exploded
perspective view of a related art discharge grill for an indoor
unit of an air conditioner.
[0007] Referring to the drawings, a main chassis 1 forms a frame of
an indoor unit. The main chassis 1 has a front frame 3 formed on a
front side thereof to form the outer appearance of the indoor unit.
The main chassis 1 having the front frame 3 is mounted on a wall in
the inside.
[0008] A space in which parts that will be described below are
mounted is formed between the main chassis 1 and the front frame
3.
[0009] In the meantime, the outer appearance of the indoor unit
formed by the main chassis 1 and the front frame 3 is protruded
toward the front side as a whole as illustrated in FIG. 1.
[0010] A suction panel 7 having a front suction grill 5 is provided
on the front of the front frame 3 to form a front appearance of the
indoor unit. A hinge member (not shown) is provided at the upper
end of the suction panel 7 to allow the suction panel 7 to
rotate.
[0011] The front suction grill 5 is a path through which air sucked
from a space that needs air-conditioning is sucked into the inside
of the indoor unit. The front suction grill 5 is integrally formed
with the suction panel 7. In the meantime, an upper suction grill
3' is formed long left and right on the upper side of the front
frame 3. The upper suction grill 3' is integrally formed with the
front frame 3 or separately formed.
[0012] A heat exchanger 9 is installed at the back of the front
frame 3. The heat exchanger 9 allows air sucked through the front
suction grill 5 and the upper suction grill 3' to exchange heat
while passing through the exchanger 9. A filter 9' for purifying
sucked air is installed on the front of the heat exchanger 9.
[0013] A cross-flow fan 10 is installed at the back of the heat
exchanger. The cross-flow fan 10 sucks air from a space that needs
air-conditioning and discharges air back to the space that needs
air-conditioning. A fan motor 10' for providing rotational power to
the cross-flow fan 10 is installed on the right side of the
cross-flow fan 10 and a member for guiding flow created by the
cross-flow fan 10 is further integrally formed in the inside of the
main chassis 1.
[0014] In the meantime, air that has heat-exchanged while passing
through the heat exchanger 9 is discharged to a space that needs
air-conditioning through the cross-flow fan 10. For that purpose, a
discharge grill 11 is installed at the lower end of the main
chassis 1 and the front frame 3.
[0015] In the meantime, a discharge flow (not shown) for guiding
air that has passed through the cross-flow fan 10 to a space that
needs air-conditioning is formed in the inside of a discharge grill
11.
[0016] A vane 15 for vertically controlling the direction of
discharged air and a louver for horizontally controlling the
direction of discharged air are installed in the inside of the
discharge flow. The louver 16 is provided in plurals and the
louvers 16 are connected to each other by a link 17 to operate
simultaneously.
[0017] A vane and a louver are installed into the inside of the
discharge flow to adjust a movement of a discharge air to up and
down, and to left and right respectively. A plurality of the
louvers 16 is connected by supporter 18 and combines with a link 17
to which a motor M attaches.
[0018] The supporter 18 is a long rod for the louver 16 to be
connected on the same plane with a straight direction. A fixing end
18' is formed to support the supporter 18 at the bottom of the
supporter 18.
[0019] A one side of the link 17 combines with the motor M and the
other side of the link 17 combines with the supporter 18 connecting
the louver 16. The link 17 has a plurality of bending portions to
move the louver 16 by a rotational power of the motor M. Referring
to FIG. 2, the link expands from a side end connecting the louver
16 to the front, to the bottom and the front with bending. The
expanded other end is connected to the motor M.
[0020] In addition, a display 19 for displaying an operation state
of an air conditioner is provided at an about center on the lower
portion of the front frame 3.
[0021] Description will be made for the air conditioner having the
above-described construction and operating in a cooling mode.
[0022] When the air conditioner operates, air for air-conditioning
is sucked into the inside of an indoor unit by the cross-flow fan
11. That is, air is sucked into the inside of the indoor unit
through the front suction grill 5 and the upper suction grill 3' to
pass through the heat exchanger 9.
[0023] The air that has passed through the heat exchanger 9
exchanges heat with working fluid (refrigerant) flowing in the
inside of the heat exchanger 9.
[0024] The air that has exchanged heat with the heat exchanger 9
becomes relatively low temperature and is sucked into the
cross-flow fan 10. The air sucked into the cross-flow fan 10 is
discharged to the lower direction and guided to the side of the
discharge port 13.
[0025] The air guided to the inside of the discharge port 13
changes a discharging direction thereof using the vane 15 and the
louver 16 installed inside the discharge port 13 and is discharged
to a space that needs air-conditioning through the discharge grill
13. At this point, since the vane 15 and the louver 16 allow the
discharged air to be distributed vertically and horizontally, the
air is uniformly discharged to the space that needs
air-conditioning.
[0026] To fix the heat exchanger 9, a fixing bracket 8 is provided
to the left of the main chassis 1 and a fixing end 8' that
corresponds to a screw-coupling end 9a of the heat exchanger 9 is
provided to the right of the main chassis 1. A screw-coupling hole
8'' should be punched in the inside of the fixing end 8'.
[0027] A receiving groove 8a for receiving a left end of the heat
exchanger 9 is formed on the front side and the upper side of the
fixing bracket 8. Hookers 8b for hooking and fixing a left hairpin
9c of the heat exchanger 9 are protruded in the inside of the
receiving groove 8a.
[0028] A screw through hole 9b that corresponds to the
screw-coupling hole 8'' is punched in the inside of the
screw-coupling end 9a of the heat exchanger 9.
[0029] The heat exchanger 9 is fixed by fixing the fixing bracket 8
in the left of the main chassis 1 using a screw S. At this point,
the receiving groove 8a of the fixing bracket 8 is open toward the
right side.
[0030] When the hairpin 9c of the heat exchanger 9 is inserted into
the receiving groove 8a of the fixing bracket 8, the hairpin 9c is
hooked at and fixed in the hooker 8b of the inside of the receiving
groove 8a. At this point, the left end of the heat exchanger 9 is
fixed first.
[0031] After that, the right side of the heat exchanger 9, more
specifically, the screw-coupling end 9a is closed attached to the
fixing end 8' of the main chassis 1 and the screen through hole 9b
is coupled to the screw-coupling hole 8'' using a screw S, so that
the heat exchanger 9 is fixed to the main chassis 1.
[0032] However, the link combines with the louver 16, the link has
a plurality of bending portions, a motor M is mounted for providing
power, a supporter 18 is connected to the louver 16 for working
together.
[0033] However, the supporter 18 is connected to simultaneously
operate a plurality of the louvers 16. A motor M is mounted for
providing horizontal movement force to the louver 16. The link 17
transfers power from the motor M to the louver 16 and combines with
the louver 16 with a plurality of bending portions.
[0034] Accordingly, since the link 17 has a plurality of bending
portions to front and rear, and to up and down with a high and low
difference, there is a loss of power for transferring power of the
motor M to the louver 16.
[0035] Additionally, since momentum for transferring power of the
motor M is focused at the `A` portion of the link 17, there is a
possible damage of the `A` portion.

at the inside of the discharge port 122.
[0056] A display window 124 is formed at an upper right of the
discharge port 122. The display window 124 is transparent so that a
user can see from the outside a display information of a discharge
grill 200 about an operating condition of the indoor unit of an air
conditioner 100.
[0057] FIG. 4 is an exploded perspective view of an indoor unit of
an air conditioner according to an embodiment of the present
invention. Referring to a FIG. 4, a construction about the indoor
unit of an air conditioner 100 will be described in more
detail.
[0058] As described above, the external appearance of the indoor
unit of an air conditioner 100 is constructed by the main chassis
110 and the front frame 120. Moreover, the main chassis is
installed on a surface of the wall of the inside.
[0059] A space is formed to mount a plurality of the parts between
the main chassis 110 and the front frame 120. The entire external
appearance of the indoor unit of an air conditioner 100 constructed
by the main chassis 110 and the front frame 120 is protruded toward
the front.
[0060] A fixing bracket 112 is equipped to fix the left end of a

right end portion of the main chassis 110.
[0061] A suction port 150 is formed at the front of the front frame
120. The suction port 150 is a path for an inflow air from the
outside and has a filter frame 160 divided into the left and right.
The filter frame 160 is a place to which a high performance filter
170 is attached to and forms the left and right portion as a pair.
That is, a central divider 152 across an upper and lower of the
filter frame 160 is formed at a central portion of the suction port
150 and each filter frame 160 is formed at the left and right side
of the central divider 152.
[0062] The high performance filter 170 is mounted at the filter
frame 160. The high performance filter 170 has at least one
functional characteristic. For example, the high performance filter
170 can be equipped with an ammonia filter for deodorizing various
smells like cigarette smoke, a formaldehyde filter for eliminating
chemical toxic from building materials, and a toluene filter for
removing the smell of a volatile organic substance.
[0063] The suction grill 140 becomes the path for an air flowing in
the indoor unit of an air conditioner 100 and is installed to wrap
the upper of the suction port 150 of the filter frame 160. The
suction grill 140 is mounted at the front frame 120, being combined
with a prefilter 180 as one body.
[0064] The prefilter 180 is installed between the front panel 130

the suction grill 140 for a heat exchange. And it is desirable that
there is a plurality of a bending portion to correspond to the
suction port 150 of the front frame 120.
[0066] The cross-flow fan 190 is installed at the rear of the heat
exchanger 190. The cross-flow fan 190 intakes and discharges an air
into the space for air conditioning. The cross-flow fan 190 forces
a flow of an air to intake the outdoor air through the suction port
150 and discharge the air through the discharge port 122.
[0067] A fan motor 194 is installed to provide a rotational power
at the right of the cross-flow fan 192. The front of the main
chassis 110 may be formed with a curvature corresponding to the
outer surface of the cross-flow fan 192 for easily guiding an air
current formed by the cross-flow fan 192.
[0068] The discharge grill 200 is equipped at the inside of the
bottom of the front frame 120. A discharge port 202 in the
discharge grill 200 is formed to discharge an air to the outside
after a heat of the air is exchanged in the indoor unit of an air

the right end portion in the front of the discharge grill 200. The
display 210 shows various information about an operating condition
of the indoor unit of an air conditioner 100. Accordingly, a user
can see from the outside a display information.
[0072] Since the display 210 is disposed at the rear of the display
window 124 in the front frame 120, a user can see about various
information on the display 210 through a display window 124,
standing in front of the indoor unit of an air conditioner 100.
[0073] FIG. 6 is a partial perspective view of a discharging grill
with a louver for an indoor unit of an air conditioner and FIG. 7
is a perspective view of a link mounted into a discharging grill
for an indoor unit of an air conditioner according to an embodiment
of the present invention.
[0074] Referring to FIGS. 6 and 7, a louver 206 is connected to the
supporter 207 and installed to adjust a direction of a air flow to
the left and right, discharging from the inside of the discharge
grill 200. The supporter 207 is formed with an enough length to
align a plurality of the louvers 206 in a straight direction. A
fixing end 209 is formed to sustain the supporter 207 at the bottom
of the supporter 207. With the above connection, the louver 206
moves to the left and right according to movement of the supporter
207 to the left and right.
[0075] The supporter 207 combines with the link 230 transferring
the power of a link motor a kind of a step motor. The link 230
combines with the link motor and another end portion of the link
230 combines with supporter 207 connected with the louver 206 on
the same plane. The link 230 is bent to the front and rear not the
left and right for the louver 206 to move to the left and right by
a rotation power of the link motor. Referring to the drawings,
there are two bending portions to the front and rear
respectively.
[0076] By this bending portion, a chance for a deformation of the
link 230 reduces and a reliable movement is possible when the link
230 moves.
[0077] A width W1 of the bending portion is broader than a width W2
of a portion expanded to combine with the link motor at the link
230. By doing this, it is possible to transfer the power to move a
plurality of the louvers 206, being connected to the supporter 207,
to the left and right without a power loss by the rotational power
of the link motor and increase a durability of the link 230.
Consequently, this embodiment provides a solution preventing the
bending portion from being easily damaged at the bending portion of
the link 230.
[0078] A link guide 234 is formed to easily move the link 230 to
the left and right at the bottom of the link 230. A fixing groove
232 is formed at the right end of the link 230 by inserting a
fixing member 240 to fix the link motor.
[0079] The fixing member coupling part is formed to easily move the
link 230 to the left and right according to a rotation of the link
motor by inserting the bottom of the fixing member 240.
Additionally, the fixing member coupling part is straight or
cross-shaped and the fixing groove 232 is equipped with the fixing
member 240 to fix the link motor.
[0080] Additionally, a motor receiving hole 242 is formed to make a
rotation easily at the fixing member 240 by inserting the side of
the link motor. A drain fan shown in FIG. 4 is formed to collect
the condensed water generated from a heat exchanger 190, the drain
fan being disposed at the bottom of the louver 206.
[0081] A working condition about the indoor unit of an air
conditioner 100 having the above discharge grill structure will be
described.
[0082] Next, the cooling mode of the air conditioner is operated
and observed.
[0083] Once the air conditioner is operated, an air flows into the
inside of the air conditioner by the cross-flow fan 192. That is,
the fan motor 194 operates and produces a rotational power by a
voltage applied from the outside. The cross-flow fan 192 rotates by
this rotational power. An outdoor air flows into the indoor unit of
an air conditioner 100 through the suction grill 140 when the
cross-flow fan 192 rotates.
[0084] The outdoor air flowing into the indoor unit 100 passes
though the heat exchanger 190. The air passing through the heat
exchanger 190 is cooled down by a refrigerant running the inside of
the heat exchanger 190.
[0085] The heat-exchanged air in the heat exchanger 190 becomes the
relatively low temperature air and flows into the cross-flow fan
192. The low temperature air flowing into the cross-flow fan 192 is
discharged in a cylindrical direction of the cross-flow fan 192 and
guided into the bottom compartment.
[0086] The guided air passes through the discharge port 202 of the
discharge grill 200. At this time, the air is discharged into the
space for an air conditioning by the vain 204 and the louver 206
installed in the inside of the discharge port 202.
[0087] Here, the louver 206 adjusts a direction of the air
discharged from the movement of the link 230 to the left and right
by the rotational power of the link motor. In more detail, the link
230 receiving the rotational power of the link motor moves to the
left and right and a connection port 201 connected to the louver
206 moves to the left in a condition of guiding the air to a slit
203 formed at the supporter 207. Accordingly, the louver 206 fixed
at the predetermined hinge portion moves to the left and right
according to the movement of the connection port 201.
[0088] According to the present invention, the link 230 moves to
the left and right by a rotation power of the link motor and is
bent to the front and rear not the left and right for the louver
206 to combine with the supporter 207 connected with a plurality of
the louvers 206 at the same plane.
[0089] Accordingly, since the link and the supporter receiving the
power of the link motor is disposed at the same plane, a loss of
power used in the movement of the louver can be reduced and the
louver can easily move to the left and right.
[0090] Moreover, the durability of the link transferring the
movement power from the link motor to the louver can be increased
by forming a bending portion of the link broader than a straight
portion.
[0091] It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention.
Thus, it is intended that the present invention covers the
modifications and variations of this invention provided they come
within the scope of the appended claims and their equivalents.
