10-2016-0009493, filed on Jan. 26, 2016 in the Korean Intellectual
Property Office, the disclosures of which are incorporated herein
by reference in their entirety.
BACKGROUND
1. Field
[0002] The following description relates to air conditioners, and
more particularly, to an air conditioner employing different air
discharging methods.
2. Description of the Related Art
[0003] In general, an air conditioner (AC) is a device for
controlling temperature, humidity, etc., to be suitable for human
activities and simultaneously, eliminating dust or other
contaminants in the air by using refrigeration cycles. The
refrigeration cycle performed using elements such as a compressor,
a condenser, an evaporator, a blower fan, etc.
[0004] The ACs may be classified into split ACs with indoor and
outdoor units separately installed, and packaged ACs with indoor
and outdoor units installed together in a single cabinet. The
indoor unit of the split AC includes a heat exchanger for
exchanging heat of the air sucked into the panel, and a blower fan
for sucking the room air into the panel and blowing the air back
into the room.
[0005] The indoor units of conventional ACs are manufactured such
that the heat exchanger is minimized in size and the air velocity
and air volume are maximized by increasing revolutions per minute
(rpm) of the blower fan. This reduces discharge temperature, and
discharges the air into the room through a narrow and long fluid
path.
[0006] When the user is directly exposed to the discharged air,
he/she might feel cold and unpleasant, and on the contrary, when
he/she is not exposed to the discharged air, he/she might feel hot
and unpleasant.
[0007] Furthermore, increasing the rpm of the blower fan to achieve
a high wind velocity may lead to a problem of increasing noise. As
for an AC using radiation for air conditioning instead of the
blower fan, it requires a large panel to have equal capabilities as
in the blower fan based AC. This may slow down the cooling speed
and increase installation costs.

[0060] Reference will now be made in detail to embodiments,
examples of which are illustrated in the accompanying drawings,
wherein like reference numerals refer to the like elements
throughout.
[0061] A refrigeration cycle of an Air conditioner (AC) is
comprised of a compressor, a condenser, an expansion valve, and an
evaporator. The refrigeration cycle circulates in a series of
processes of compression, condensing, expansion, and evaporation,
enabling heat exchange between high temperature air and low
temperature refrigerants and then supplying the cooled air into the
room.
[0062] The compressor compresses a gas refrigerant into a high
temperature and high pressure state and discharges the compressed
gas refrigerant, and the discharged gas refrigerant flows into the
condenser. The condenser condenses the compressed gas refrigerant
into a liquid state, releasing heat to the surroundings. The
expansion valve expands the high temperature and high pressure
liquid refrigerant condensed by the condenser to low pressure
liquid refrigerant. The evaporator evaporates the refrigerant
expanded by the expansion valve. The evaporator achieves a cooling
effect using latent heat of vaporization of the refrigerant to
exchange heat with an object to be cooled, and has low temperature
and low pressure gas refrigerant return to the compressor. Through
this refrigeration cycle, the temperature of indoor air may be
controlled.
[0063] An outdoor unit of an AC refers to a part comprised of the
compressor of the refrigeration cycle, and an outdoor heat
exchanger. The expansion valve may be placed in one of the indoor
or outdoor units, and the indoor heat exchanger is placed in the
indoor unit of the AC.
[0064] In the present disclosure, an AC for cooling the room is
provided, where the outdoor heat exchanger serves as the condenser
while the indoor heat exchanger serves as the evaporator.
Hereinafter, for convenience of explanation, an indoor unit
including the indoor heat exchanger is called an AC, and the indoor
heat exchanger is called a heat exchanger.
[0065] FIG. 1 is a perspective view of an AC, according to an
embodiment of the present disclosure.
[0066] An indoor unit of an AC 1 may include a housing 10 having at
least one opening 17 and forming the exterior of the indoor unit, a
heat exchanger 20 for exchanging heat with the air flowing into the
housing 10, a blower 30 for circulating air into or out of the
housing 10, and an air discharger 40 for discharging the air blown
from the blower 30 out of the housing 10.
[0067] The housing 10 may include a front panel 10a with the at
least one opening 17 formed thereon, a back panel 10b arranged in
the back of the front panel 10a, side panels 10c arranged between
the front and back panels 10a and 10b, and top/bottom panels 10d
arranged on the top/bottom of the side panels 10c. The at least one
opening 17 may have a circular shape, and at least two or more
openings 17 may be arranged on the front panel 10a at predetermined
intervals in the vertical direction. The back panel 10b may have an
inlet 19 formed to suck the outside air into the housing 10.
[0068] The inlet 19 formed on the back panel 10b arranged in the
back of the heat exchanger 20 may guide the air outside the housing
10 to flow into the housing 10. The air flowing into the housing 10
through the inlet 19 absorbs or loses heat while passing the heat
exchanger 20. The air that has exchanged heat while passing the
heat exchanger 20 is discharged by the blower 30 out of the housing
10 through an outlet.
[0069] The blower 30 may include a blower fan 32 and a blower grill
34.
[0070] The blower grill 34 may be arranged in the direction in
which the blower fan 32 discharges air. In the embodiment, the
blower fan 32 may be a mixed flow fan without being limited
thereto, and may be any kind of fan that moves the outside air into
the housing 10 and discharges the air out of the housing 10. For
example, the blower fan 32 may be a cross fan, a turbo fan, or a
sirocco fan. There is no limitation on the number of the blower
fans 32, and in the embodiment of the present disclosure, there may
be at least one blower fan 32 corresponding to the at least one
opening. The blower fan 32 may be arranged in front of the inlet
19, and the heat exchanger 20 may be arranged between the blower
fan 32 and the inlet 19. A first discharger 41 may be arranged in
front of the blower fan 32.
[0071] The blower 30 may have a fan driver 33 arranged in the
center of the blower fan 32 for driving the blower fan 32. The fan
driver 33 may include a motor.
[0072] The blower grill 34 may be arranged in front of the blower
fan 32 for guiding airflow. Furthermore, the blower grill 34 may be
arranged between the blower fan 32 and the air discharger 40 for
minimizing the influence of the outside condition on the blower fan
32.
[0073] The blower grill 34 may include a plurality of wings 35. The
plurality of wings 35 may control the direction or the volume of
the air blown from the blower fan 32 to the air discharger 40 by
controlling the number, shape, and/or angle of disposition of the
wings 35.
[0074] As will be described later, a door operating part 66 may be
arranged in the center of the blower grill 34. The door operating
part 66 and the fan driver 33 may be aligned in the back and forth
direction. With the arrangement, the plurality of wings 35 of the
blower grill 34 may be arranged in front of the fan wings of the
blower fan 32.
[0075] The blower 30 may include a duct 36. The duct 36 may be
formed to have a circular shape that encloses the blower fan 32 to
guide airflow of the air flowing into the blower fan 32. In other
words, the air sucked in through the inlet 19 and having passed the
heat exchanger 20 may be guided to flow into the blower fan 32.
[0076] The heat exchanger 20 is arranged between the blower fan 32
and the inlet 19 for absorbing heat from or transferring heat to
the air flowing in through the inlet 19. The heat exchanger 20 may
include a tube 21, and headers 22 combined on the upper and bottom
sides of the tube 21. However, the type of the heat exchanger 20 is
not limited thereto.
[0077] There may be at least one heat exchanger 20 arranged inside
the housing 10 to correspond to the number of the openings.
[0078] The air discharger 40 is arranged in the housing 10 for
discharging the air that has exchanged heat inside the housing 10
out of the housing 10. The air discharger 40 may include a first
discharger 41 and a second discharger 50, which will be described
later.
[0079] FIGS. 2 and 3 are exploded views of an AC, according to an
embodiment of the present disclosure, and FIG. 4 is a
cross-sectional view of the AC cut along the line A-A' of FIG.
[0080] The AC 1 may be configured to operate in different operation
modes. The operation modes may include a first mode for discharging
the heat exchanged air to the opening 17 formed on the housing 10,
and a second mode for discharging the heat exchanged air to a
discharging plate 14 formed on the housing 10. In addition, there
may be a third mode for discharging the heat exchanged air both to
the opening 17 and the discharging plate 14. The discharging plate
14 will be described later.
[0081] In the respective first, second, and third modes, the heat
exchanged air may be discharged through at least one of the first
and second dischargers 41 and 50. The heat exchanged air may also
be discharged both to the first and second dischargers 41 and 50.
In other words, the air that has exchanged heat by the heat
exchanger 20 may be discharged by the blower fan 32 out of the AC 1
through at least one of the first and second dischargers 41 and
50.
[0082] In the first mode, the heat exchanged air is discharged to
the first discharger 41, in which case the heat exchanged air is
not entirely discharged to the first discharger 41 but partly
discharged to the second discharger 50. That is, in the first mode,
the majority of the heat exchanged air is discharged to the first
discharger 41. Even in the second mode, as in the first mode, the
majority of the heat exchanged air is discharged to the second
discharger 50.
[0083] The air that has passed the blower 30 may be discharged out
of the housing 10 through the air discharger 40.
[0084] Again, the air discharger 40 may include the first
discharger 41 and the second discharger 50. The heat exchanged air
may be discharged through at least one of the first and second
dischargers 41 and 50. Furthermore, the heat exchanged air may be
selectively discharged through at least one of the first and second
dischargers 41 and 50.
[0085] The first discharger 41 may discharge air through an opening
formed on the housing 10. While the AC 1 is operating in the first
mode, the heat exchanged air may be discharged out of the housing
10 through the first discharger 41. The first discharger 41 is
formed to discharge the heat exchanged air directly to the outside.
The first discharger 41 may be formed to be exposed outside the
housing 10.
[0086] The first discharger 41 may be arranged in the blowing
direction of the blower fan 32 for discharging the heat exchanged
air directly to the outside. In other words, the first discharger
41 is arranged in front of the blower fan 32 of the blower 30 such
that the air blown from the blower 30 is discharged directly to the
first discharger 41.
[0087] The air blown from the blower fan 32 may flow through a
first discharging fluid path 41a (see FIG. 9) formed between the
blower fan 32 and the first discharger 41. The first discharging
fluid path 41a may be formed by a discharging guide 45.
[0088] The first discharger 41 may be formed by a guide opening 43.
The guide opening 43 may be formed to be connected to the opening
17 and form the first discharger 41 along the inner circumference
of the guide opening 43. The guide opening 43 may be formed to be
exposed outside through the opening 17 of the housing 10, and
formed to enable a door unit 60, which will be described below, to
be safely placed in the guide opening 43. The guide opening 43 may
be arranged in the opening 17 of the housing 10 and may form the
first discharger 41 along the inner circumference of the guide
opening 43.
[0089] The first discharger 41 may be formed to be opened/shut by
the door unit 60.
[0090] The door unit 60 opens/shuts the first discharger 41, and is
formed to discharge the heat exchanged air out of the housing 10
selectively through the first discharger 41. The door unit 60 may
control the heat exchanged air to flow to at least one of the first
and second dischargers 41 and 50 by opening/shutting the first
discharger 41.
[0091] The door unit 60 is formed to be movable between a door open
position 60a (see FIGS. 8 and 9) to open the first discharger 41
and a door shut position 60b (see FIGS. 10 and 11) to shut the
first discharger 41. The door unit 60 may be formed to be movable
between the door open position 60a and the door shut position 60b
back and forth.
[0092] Specifically, the door unit 60 may include a door blade 62,
and a door operating part 66 for operating the door blade 62.
[0093] The door blade 62 may be shaped like a circle corresponding
to the shape of the first discharger 41. When the door unit 60 is
in the door open position 60a, the door blade 62 is arranged to be
at some distance from the guide opening 43, and when the door unit
60 is in the door shut position 60b, the door blade 62 is arranged
to contact the guide opening 43 to shut the first discharger
41.
[0094] The door blade 62 may include a blade body 63 having a
circular form to correspond to the first discharger 41, and a blade
combiner 64 formed to extend from the blade body 63 to be combined
with the door operating part 66.
[0095] The blade body 63 may be shaped like almost a round plate.
Furthermore, the blade body 63 may be formed such that one side of
the blade body 63 faces the outside of the housing 10 and the other
side of the blade body 63 faces the blower 30.
[0096] A display is arranged on one side of the blade body 63 for
displaying operation states of the AC 1 or allowing the user to
manipulate the AC 1.
[0097] The door operating part 66 may be formed for the door blade
62 to be movable. The door operating part 66 may include a motor
(not shown). The door operating part 66 may be combined with the
blade combiner 64 of the door blade 62 to move the door blade
62.
[0098] The aforementioned blower grill 34 may be arranged along the
circumference of the door operating part 66. The air blown from the
blower fan 32 arranged on the back of the blower grill 34 may pass
the blower grill 34 and be discharged ahead.
[0099] The second discharger 50 may be arranged to discharge air
through an outer panel. While the AC 1 is operating in the second
mode, the heat exchanged air may be discharged out of the housing
10 through the second discharger 50. This arrangement enables the
heat exchanged air to be discharged to the outside while the wind
velocity of the heat exchanged air is reduced. The second
discharger 50 may be formed on the discharging plate 14, which will
be described below, and may include a plurality of discharging
holes bored through the inner and outer sides of the discharging
plate 14. The opening 17 of the housing 10 may be arranged on the
discharging plate 14 as shown in FIGS. 2 and 4, without being
limited thereto. For example, it is also possible for the opening
17 and the discharging plate 14 to be arranged on the different
sides of the housing 10.
[0100] In the case that the heat exchanged air is discharged out of
the housing 10 through the second discharger 50, the air blown by
the blower fan 32 may flow through the second discharging fluid
path 50a formed between the blower fan 32 and the second discharger
50. The second discharging fluid path 50a may be formed by the
discharging guide 45 and a discharging panel 12, which will be
described below.
[0101] The external panel may include an exterior panel 11 forming
the exterior, and the discharging panel 12 formed to discharge the
heat exchanged air. The discharging panel 12 may be part of the
external panel, or may be part of the discharger. The exterior
panel 11 may form a panel opening with the front open, and the
discharging panel 12 may be placed in the panel opening for
enabling the heat exchanged air to be discharged out of the AC
through the discharging panel 12.
[0102] The discharging panel 12 may be arranged to form the second
discharging fluid path 50a. The heat exchanged air may be
discharged out of the AC 1 through the second discharging fluid
path 50a formed by the discharging panel 12 and through the
discharging plate 14 as will be described below, at a low
velocity.
[0103] In the embodiment of the present disclosure, the discharging
panel 12 is arranged on the front of the AC 1 as shown in FIGS. 1,
2, and 3, without being limited thereto. For example, the
discharging panel 12 may be arranged on at least one of the front,
the right side, the left side, the rear side, and the top of the AC
1.
[0104] The discharging panel 12 may include a fluid path shaping
frame 13 and the discharging plate 14.
[0105] The fluid path shaping frame 13 is formed to guide the air
that has exchanged heat on an inner side of the discharging plate
14 to the discharging plate 14. The fluid path shaping frame 13 may
be formed to partition the inside of the housing 10 from the second
discharging fluid path 50a. The fluid path shaping frame 13 may
prevent the heat exchanged air from flowing back into the housing
10. In the embodiment of the present disclosure, the fluid path
shaping frame 13 may be formed to extend from the blower grill 34
to be connected to the exterior panel 11.
[0106] The second discharger 50 may be formed on the discharging
plate 14. The discharging plate 14 and the second discharger 50 may
be collectively called a plate discharger. The discharging plate 14
may be arranged to cover the panel opening.
[0107] The shape of the second discharger 50 has no limitation, but
in the embodiment of the present disclosure, may have the form of a
plurality of discharging holes. The second discharger 50 may be
formed to bore through the front and back faces of the discharging
plate 14. The discharging plate 14 may be arranged on an outer side
compared to the fluid path shaping frame 13, forming the second
discharging fluid path 50a with the fluid path shaping frame
13.
[0108] The second discharger 50 may include a discharging area
formed on at least a portion of the discharging plate 14. In the
discharging area, a plurality of discharging holes may be formed
such that they are uniformly distributed or concentrated in at
least a portion of the discharging area. In the embodiment of the
present disclosure, the discharging area has a plurality of
uniformly distributed holes.
[0109] The discharging area may be formed at least a portion of the
discharging plate 14. It is, however, not limited thereto, but may
be formed all over the discharging plate 14.
[0110] In the aforementioned third mode, the heat exchanged air is
divided to the first and second dischargers 41 and 50 and
discharged. An amount of division for each discharger may depend on
settings, or may be adjusted by the controller.
[0111] The air discharger 40 may include the first discharging
fluid path 41a for guiding the heat exchanged air to the first
discharger 41, and the second discharging fluid path 50a for
guiding the heat exchanged air to the second discharger 50. The
first and second discharging fluid paths 41a and 50a may be
referred to as a discharging fluid path and a radiation discharging
fluid path, respectively.
[0112] The air blown by the blower fan 32 may flow through at least
one of the first and second discharging fluid paths 41a and
50a.
[0113] In the first mode, the air blown by the blower fan 32 may
flow through the first discharging fluid path 41a formed between
the blower fan 32 and the first discharger 41. In the second mode,
the air blown by the blower fan 32 may flow through the second
discharging fluid path 50a formed between the blower fan 32 and the
second discharger 50.
[0114] The air discharger 40 may include a discharging guide 45.
The air blown by the blower fan 32 may be controlled by the
discharging guide 45. The discharging guide 45 may be arranged in
front of the blower 30 for enabling the air flowing from the blower
30 to flow through at least one of the first and second discharging
fluid paths 41a and 50a.
[0115] The discharging guide 45 may include a guide body 46 and a
guide groove 47.
[0116] The guide body 46 may be formed to form the first
discharging fluid path on the inside. The guide body 46 may be
shaped like a cylinder with a cavity. Specifically, the guide body
46 may have the form of a pipe with one side facing the blower 30
and the other side facing the first discharger 41.
[0117] The guide groove 47 may be formed for the second discharging
fluid path 50a to pass through. The guide groove 47 may be formed
on the guide body 46. There is no limitation on the shape of the
guide groove 47, and the guide groove 47 may have any shape if only
it is formed on the guide body 46 for enabling the air to flow to
the outer direction of the guide body 46. In the embodiment of the
present disclosure, the guide groove 47 may be formed to have a
plurality of halls along the circumference of the guide body
46.
[0118] In the first mode, the door unit 60 opens the first
discharger 41. In this case, the air blown from the blower 30
passes the first discharging fluid path 41a formed inside of the
guide body 46 and is discharged to the first discharger 41.
[0119] In the second mode, the door unit 60 shuts the first
discharger 41. In this case, one side of the guide body 46 is shut
by the door unit 60, forcing the air blown from the blower 30 to
pass the guide groove 47 formed on the guide body 46 and is
discharged to the second discharger 50.
[0120] An area of the first discharger 41 may be twice the area of
the second discharger 50. Specifically, total area of the plurality
of discharging holes of the second discharger 50 may be 0.5 times
or more than the area of a first discharging hole 42 (see FIG. 9)
formed between the first discharger 41 and the door unit 60.
Furthermore, total area of the plurality of discharging holes of
the second discharger 50 may be 10 times or less than the area of
the first discharging hole 42 formed between the first discharger
41 and the door unit 60. With this structure, while the AC is
operating in the first mode, the air may be easily blown to the
first discharger 41 or the first discharging hole 42 rather than to
the second discharger 50. The area of the second discharger 50 has
no limitation. For example, the plurality of discharging holes of
the second discharger 50 may each have the area of 0.05 mm.sup.2 or
more. It is because the air may not easily flow to the second
discharger 50 if each of the plurality of discharging holes has the
area of 0.05 mm.sup.2 or less. In an example, each of the plurality
of discharging holes of the second discharger 50 may have the area
of 5 mm.sup.2 or less. The respective discharging holes may have
equal or different areas.
[0121] FIG. 5 shows a combination of a discharging plate and a
housing, according to an embodiment of the present disclosure, and
FIGS. 6 and 7 show a combination of a discharging plate and a guide
opening, according to an embodiment of the present disclosure.
[0122] The discharging plate 14 may include plate combiners 15a,
15b. The plate combiners 15a, 15b may be formed to combine the
discharging plate 14 with the housing 10 or the guide opening
43.
[0123] The plate combiner 15a may be formed along the contour of
the discharging plate 14 for combination with the housing 10. The
plate combiner 15b may be formed along the contour of the opening
17 of the discharging plate 14 for combination with the guide
opening 43.
[0124] The plate combiners 15a, 15b may be formed to protrude from
the discharging plate 14. The plate combiners 15a, 15b may include
plate rabbet grooves 16a, 16b shaped like holes, to catch
projections 17, 43b, which will be described later.
[0125] The plate combiners 15a, 15b may include the first plate
combiner 15a to combine the discharging plate 14 with the housing
10, and the second plate combiner 15b to combine the discharging
plate 14 with the guide opening 43.
[0126] At least one first plate combiner 15a may be arranged along
the contour of the discharging plate 14. The first plate combiner
15a is combined with the housing 10 to combine the housing 10 and
the discharging plate 14.
[0127] A first projection 18 may be arranged on the housing 10 at a
position corresponding to the first plate combiner 15a. In the
embodiment of the present disclosure, the first projection 18 is
arranged at a position corresponding to the first plate combiner
15a on the outer edge of the fluid path shaping frame 13. However,
where to arrange the first projection 18 is not limited thereto, if
only the first projection 18 is arranged to correspond to the first
plate combiner 15a such that the housing 10 and the discharging
plate 14 are combined.
[0128] As shown in FIG. 5, in a case of having the discharging
plate 14 closely contact the housing 10, the first plate rabbet
groove 16a of the first plate combiner 15a is formed to catch the
first projection 18. This enables the discharging plate 14 to be
attached onto the housing 10.
[0129] There is no limitation on the number of the first plate
combiners 15a and the number of the first projections 18.
[0130] At least one second plate combiner 15b may be arranged along
the contour of the opening 17, as shown in FIG. 6. The second plate
combiner 15b is combined with the guide opening 43 to combine the
guide opening 43 and the discharging plate 14.
[0131] A guide insertion groove 43a may be formed in the guide
opening 43 for the second plate combiner 15b to be inserted
thereto. When the discharging plate 14 and the guide opening 43
have close contact with each other, the second plate combiner 15b
may be inserted through the guide insertion groove 43a, passing
through the guide opening 43. The guide insertion groove 43a may be
arranged along the circumference of the guide opening 43 to
correspond to the second plate combiner 15b arranged on the outer
edge of the opening.
[0132] The second plate combiner 15b may be inserted into the guide
insertion groove 43a such that the second projection 43b is caught
in the second plate rabbet groove 16b, thereby combining the
discharging plate 14 and the guide opening 43. As such, combining
the discharging plate 14 and the guide opening 43 may connect the
opening 17 and the first discharger 41.
[0133] There is no limitation on the number of the second plate
combiners 15b, second projections 43b, and guide insertion grooves
43a, but in the embodiment of the present disclosure, the second
plate combiners 15b, second projections 43b, and guide insertion
grooves 43a all have four each.
[0134] Operation of the AC in accordance with an embodiment of the
present disclosure will now be described.
[0135] FIGS. 8, 9, 10, and 11 illustrate operation of an AC,
according to an embodiment of the present disclosure.
[0136] The air flowing into the housing 10 from outside exchanges
heat with the heat exchanger 20. The air that has been
air-conditioned by the heat exchanger 20 is discharged by the
blower 30 out of the housing 10.
[0137] The AC 1 discharges the air that has passed the heat
exchanger 20 through at least one of the first and second
dischargers 41 and 50. For example, the AC 1 may discharge the air
through the first discharger 41 to perform intensive air
conditioning in the first mode, or may discharge the air through
the second discharger 50 to slow down air conditioning all over the
room in the second mode.
[0138] The first discharger 41 may be opened/shut by operation of
the door unit 60. If the first discharger 41 is opened, the heat
exchanged air is discharged through the first discharger 41, and if
the first discharger 41 is shut, the heat exchanged air is
discharged through the second discharger 50.
[0139] Operation of the AC 1 in the first mode will now be
described in more detail.
[0140] FIGS. 8 and 9 illustrate an AC operating in the first
mode.
[0141] In the first mode, the heat exchanged air is discharged
through the first discharger 41. In the first mode, when the door
unit 60 is in the door open position 60a, the door blade 62 is at
some distance from the guide opening 43, enabling the first
discharger 41 to be opened.
[0142] In this case, the air flowing from the blower 30 flows
through the first discharging fluid path 41a formed by the guide
body 46 to the first discharger 41.
[0143] In this case where the air is discharged out of the housing
10 through the first discharger 41, the wind velocity of the blower
30 remains constant.
[0144] Operation of the AC 1 in the second mode will now be
described in more detail.
[0145] FIGS. 10 and 11 illustrate an AC operating in the second
mode.
[0146] In the second mode, the heat exchanged air is discharged
through the second discharger 50. In the second mode, when the door
unit 60 is in the door shut position 60b, the door blade 62 comes
into contact with the guide opening 43 to shut the first discharger
41.
[0147] In this case, the air flowing from the blower 30 passes the
guide groove 47 formed on the guide body 46 because the first
discharger 41 is blocked by the door blade 62. Thus, the air
flowing from the blower 30 flows through the second discharging
fluid path 50a to the second discharger 50.
[0148] In this case where the air is discharged out of the housing
10 through the second discharger 50, the air slows down while
passing the plurality of discharging holes of the discharging plate
14 and is discharged to the outside at a low velocity.
[0149] With this structure, the AC 1 may cool or heat the room at a
wind velocity that makes the user feel pleasant.
[0150] The first and second dischargers 41 and 50 may also be
called a high-rate discharger and a low-rate discharger,
respectively.
[0151] Operation of the AC 1 in the third mode will now be
described in more detail.
[0152] In the third mode, the heat exchanged air is discharged out
of the housing 10 by being divided into the first and second
dischargers 41 and 50. An amount of division for each discharger
may depend on settings or may be adjusted by the controller.
Alternatively, it may be adjusted depending on the surrounding
conditions sensed by some temperature sensor.
[0153] An AC in accordance with an embodiment of the present
disclosure will now be described.
[0154] Arrangements overlapping with what are described above will
be omitted herein.
[0155] FIG. 12 shows a discharging plate 914, according to an
embodiment of the present disclosure.
[0156] A second discharger 950 may be formed on a discharging plate
914.
[0157] The discharging plate 914 may be formed by a press forming
process. The discharging plate 914 may be formed by performing a
press forming process on a metal plate 910, and a second discharger
950 may be formed by a perforating process. The press forming
process to form at least one opening 915 of the discharging plate
914 and the perforating process to form the second discharger 950
may be performed simultaneously or independently.
[0158] An AC in accordance with an embodiment of the present
disclosure will now be described.
[0159] Arrangements overlapping with what are described above will
be omitted herein.
[0160] FIGS. 13 and 14 show a discharging plate, according to an
embodiment of the present disclosure.
[0161] A discharging plate 1014 may include a discharging sheet
1015 and a support frame 1016.
[0162] A second discharger 1050 may be formed on the discharging
sheet 1015. The second discharger 1050 may include a plurality of
discharging holes. The second discharger 1050 may be formed on the
discharging sheet 1015 by a perforating process.
[0163] The discharging sheet 1015 may be formed to be mounted on
the front of the support frame 1016. The discharging sheet 1015 may
be supported by the support frame 1016 to avoid deformation.
[0164] The discharging sheet 1015 may include at least one sheet
opening 1015c. The at least one sheet opening 1015c may have the
form of an opening to correspond to the at least one first
discharger 41.
[0165] The discharging sheet 1015 may be formed to be detachable
from the support frame 1016 as will be described below. This
enables the discharging sheet 1015 to be separated therefrom for
cleaning, facilitating easy maintenance of the AC.
[0166] The support frame 1016 may include a plurality of supporters
1017.
[0167] The plurality of supporters 1017 are arranged to support the
rear side of the discharging sheet 1015 to avoid the discharging
sheet 1015 from being wrinkled but to keep it straight on the front
of the support frame 1017. Because the discharging sheet 1015 is
arranged as the exterior of the AC, it may prevent the user from
getting hurt by the internal parts of the AC.
[0168] The support frame 1016 may include at least one frame
opening 1016a. The at least one frame opening 1016a may have the
form of an opening to correspond to the at least one first
discharger 41. The discharging sheet 1015 and the support frame
1016 may be combined to match the frame opening 1016a and the sheet
opening 1015c.
[0169] The discharging sheet 1015 may include a sheet body 1015a,
and a sheet combiner 1015b arranged on both ends of the sheet body
1015a.
[0170] The second charger 1050 is formed on the sheet body 1015a.
The sheet body 1015a and the second discharger 1050 may be arranged
to form a shape of net. In other words, the sheet body 1015a may be
formed to have the form of a net to form the second discharger 1050
for discharging air.
[0171] The sheet body 1015a is supported by the support frame 1016,
and the sheet combiner 1015b is formed to be bendable from the
sheet body 1015a. The sheet combiner 1015b may be put in between
both ends of the support frame 1016 and the housing, as shown in
FIG. 14.
[0172] Specifically, frame combining grooves 1010a corresponding to
either end of the support frame 1016 are formed on the housing
1010, and frame projections 1016b corresponding to the frame
combining grooves 1010a may be formed at either end of the support
frame 1016. The sheet combiner 1015b may be arranged between the
frame combining groove 1010a and the frame projection 1016b to put
the support frame 1016 into the housing 1010, thereby enabling the
discharging sheet 1015 to be fixed.
[0173] The material of the discharging sheet 1015 has no
limitation, and in the embodiment of the present disclosure, the

out of the AC through the discharging panel 112.
[0245] The discharging panel 112 may include a fluid path shaping
frame 113 and the discharging plate 114.
[0246] The fluid path shaping frame 113 is located in the back of
the discharging plate 114 for guiding the air that has exchanged
heat by the heat exchanger to the discharging plate 114.
[0247] The discharging plate 114 may be formed to discharge the
heat exchanged air to the outside. The discharging plate 114 may be
formed to create a gap G from the inner side of the exterior panel
111 facing at least some portion of the circumference of the

plate 114 from coming into contact with the exterior panel 111 on a
side. The width of the gap G has no limitation, and may depend on
types of the AC.
[0248] The heat exchanged air may change in temperature while
passing the discharging plate 114. In this case, because the
discharging plate 114 is formed not to come into direct contact
with the exterior panel 111 on a side, direct heat conduction may
be prevented between the discharging plate 114 and the exterior
panel 111. It may also prevent condensation buildup on the exterior
panel 111 and improve heat efficiency.
[0249] The discharging plate 114 may include a plate flange
115.
[0250] The plate flange 115 may be formed on at least a portion of
the circumference of the discharging plate 114. The plate flange
115 is formed to fix the discharging plate 114 to the AC. The plate
flange 115 may be formed to be bent from the circumference of the
discharging plate 114. With this structure, the plate flange 115
may enclose the circumference of the fluid path shaping frame 113.
The plate flange 115 is arranged between the fluid path shaping
frame 113 and the exterior panel 111 for fixing the discharging
plate to the AC. Although in the present embodiment, the plate
flange 115 is formed along the left, right, and top edges of the

integrally formed with the exterior panel 111, but in the
embodiment, it is formed separately from the exterior panel 111.
The facing face 118 of the exterior panel 111 may be formed on the
combining guide 117.
[0253] The combining guide 117 may include a panel combiner 117a
and a frame combiner 117b. The panel combiner 117a is arranged on
one side of the combining guide 117 to be combined with the
exterior panel 111, and the frame combiner 117b is arranged on the
other side of the combining guide 117 to be combined with the fluid
path shaping frame 113. The facing face 118 may be formed on the
inner side of the panel combiner 117a. There is no limitation on
how to combine the panel combiner 117a and the frame combiner 117b
with the exterior panel 111 and the fluid path shaping frame 113,
respectively. For example, they may be combined by fitting or
screwing.
[0254] In combining the combining guide 117 of the exterior panel
111 and the fluid path shaping frame 113, an insertion groove 120
may be formed between the combining guide 117 and the fluid path
shaping frame 113 for the discharging plate 114 to be inserted
thereto. The plate flange 115 of the discharging plate 114 is
inserted to the insertion groove 120. Specifically, the fluid path
shaping frame 113 may include a frame flange 113a formed along the
circumference of the fluid path shaping frame 113, and the
insertion groove 120 may be formed between the frame flange 113a
and the facing face 118 of the combining guide 117.
[0255] The combining guide 117 may include a separation member
119.
[0256] The separation member 119 is arranged to separate the plate
flange 115 and the facing face 118 of the combining guide 117, such

flange 115 does not come into direct contact with the plate flange
115. The separation member 119 may be formed on the facing face 118
of the combining guide 117.
[0257] The separation member 119 may have the form of a projection,
which is formed to protrude from the facing face 118. The
separation member 119 may protrude from the facing face 118 by
being extended from the facing face 118 in the back and forth
direction. There is no limitation on the shape of the separation
member 119, and for example, the separation member 119 may be
formed to elongate in the longitudinal direction of the combining
guide 117.
[0258] A plurality of separation members 119 may be arranged along
the facing face 118 at some intervals.
[0259] The separation member 119 may be an example in forming the
gap G between the plate flange 115 and the exterior panel 111. In
the present embodiment, the separation member 119 may have the form
of a projection, without being limited thereto, forming the gap G
between the plate flange 115 and the exterior panel 111.
[0260] An AC in accordance with an embodiment of the present
disclosure will now be described.
[0261] Arrangements overlapping with what are described above will
be omitted herein.
[0262] FIG. 29 is a cross-sectional view of combination of a
exterior panel and a discharging panel, according to an embodiment
of the present disclosure.
[0263] Although a combining guide 217 is separately formed from an
exterior panel 211 in the embodiments of FIGS. 27 and 28, they are
integrally formed in the present embodiment of FIG. 29. With this
structure, the combining guide 217 may be stably supported by the
exterior panel 211, and may stably support the discharging panel
112 as well. Furthermore, as the combining guide 217 is integrally
formed with the exterior panel 211, errors between elements may be
reduced, thereby keeping the gap G formed between the discharging
plate 114 and the exterior panel 211 constant.
[0264] An AC in accordance with an embodiment of the present
disclosure will now be described.
[0265] Arrangements overlapping with what are described above will
be omitted herein.
[0266] FIG. 30 is a cross-sectional view of combination of an
exterior panel and a discharging panel, according to an embodiment
of the present disclosure.
[0267] In the present embodiment, the separation member may include
a first separation projection 119a and a second separation
projection 119b.
[0268] The first separation projection 119a is arranged on the
exterior panel 111 such that the outer side of the plate flange 115
and the inner side of the exterior panel 111 form a first gap G1.
Specifically, the first separation projection 119a is formed to
protrude from the facing face 118 of the combining guide to be able
to contact the outer side 115c of the plate flange 115, whereby the
facing face 118 of the combining guide and the outer side 115c of
the plate flange 115 form the first gap G1.
[0269] The second separation projection 119b is arranged on the
fluid path shaping frame 113 such that the inner side 115d of the
plate flange 115 and the outer side of the fluid path frame 113
form a second gap G1. Specifically, the second separation
projection 119b is formed to protrude from the outer side 113b of
the fluid path shaping frame 113 to be able to contact the inner
side 115d of the plate flange 115, whereby the outer side 113b of
the fluid path shaping frame 115 and the inner side 115d of the
plate flange 115 form the gap G.
[0270] As such, preventing the inner or outer side of the plate
flange 115 from coming into contact with the neighboring element on
the side may prevent direct heat conduction to the neighboring
element while the heat exchanged air is being discharged through
the discharging plate 114. It may also prevent condensation buildup
on the neighboring element and improve heat efficiency. In the
present embodiment, separation projections 119a, 119b are formed on
the inner and outer sides of the discharging plate 114, without
being limited thereto. For example, there may be a separation
projection formed to be able to contact only the inner side of the
plate flange 115.
[0271] An AC in accordance with an embodiment of the present
disclosure will now be described.
[0272] Arrangements overlapping with what are described above will
be omitted herein.

The plate flange 315 may be arranged to be fixed to the combining
guide 317 while being separated from a facing face 318 of the
combining guide that faces the plate flange 315.
[0277] The plate flange 315 may be fixed to the combining guide 317
with, for example, a fixing projection 315d formed on the plate
flange 315 and a fixing groove 317c formed on the combining guide
317 to correspond to the fixing projection 315d. The plate flange
315 and the combining guide 317 may be fixed together by inserting
the fixing projection 315d to the fixing groove 317c. The fixing
projection 315d and the fixing groove 317c may be combined in the
back and forth direction of the AC. This may prevent the
discharging plate 314 from moving in the side direction, thereby
preventing a change in width of the gap G.
[0278] In the present embodiment, the plate flange 315 is combined
with the combining guide 317 but separated from the inner side of
the combining guide by means of the fixing projection 315d and the
fixing groove 317c, without being limited thereto. Any elements or

[0286] The combining guide 417 may include a separation member 419
formed to protrude from the insertion face. The separation member
419 may be arranged to be able to come into contact with the plate
flange 415 such that the plate flange 415 is separated from the
outer face of the insertion faces.
[0287] Specifically, the insertion faces may include a first
insertion face 418a facing the inner side of the plate flange 415
and a second insertion face 418b facing the outer side of the plate
flange 415. The separation member 419 may be formed on the second
insertion face 418b such that the plate flange 415 and the second
insertion face 418b may be separated with a gap G. The second
insertion face 418b may also be referred to as a facing face
418.
[0288] The separation member 419 may have the form of a projection
that may be extended in the back and forth direction of the AC. The
form of the separation member 419 is not, however, limited thereto,
and any form is possible if only it keeps the gap G between the
plate flange 415 and the second insertion face 418b.
[0289] Several embodiments have been described above, but a person
of ordinary skill in the art will understand and appreciate that
various modifications can be made without departing the scope of
the present disclosure. Thus, it will be apparent to those ordinary
skilled in the art that the true scope of technical protection is
only defined by the following claims.
[0290] The AC according to embodiments of the present disclosure
may discharge heat exchanged air at different wind velocities.
[0291] The AC may employ different methods for blowing heat
exchanged air depending on the surroundings of the user.
[0292] Furthermore, the AC may perform air conditioning in the room
not to expose the user directly to the heat exchanged air, thereby
increasing user satisfaction.
