at the window, etc. under the state that an outdoor unit and an
indoor unit are integrally assembled in one case, and the separate
type air conditioner is respectively installed at the outdoor and
the indoor under the state that the outdoor unit and the indoor
unit are separated from each other.
[0004] FIG. 1 is a disassembled perspective view showing a window
type air conditioner in accordance with the conventional art, and
FIG. 2 is an engagement sectional view showing the window type air
conditioner in accordance with the conventional art.
[0005] The conventional window type air conditioner comprises: a
case 102 of which one side is positioned at the outdoor side and
another side is positioned at the indoor side; an outdoor unit 104
installed at the outdoor side of the case 102 and heat-exchanged
with the outdoor air; and an indoor unit 106 installed at the
indoor side of the case 102 and heat-exchanged with the indoor
air.
[0006] The case 102 is installed at the wall that divides the
outdoor and the indoor, and one side of the case 102 is positioned
at the outdoor and another side thereof is positioned at the
indoor. An outdoor air suction port 108 for sucking outdoor air is
formed at both lateral surfaces of the case 102 positioned at the
outdoor side. Also, an outdoor air discharge port 110 for
discharging the air heat-exchanged while passing through the
outdoor unit 104 outdoors is formed at the rear surface of the case
108. At the front surface of the case 108 positioned at the indoor
side, an indoor air suction port 112 for sucking the indoor air and
an indoor air discharge port 114 for discharging the air
heat-exchanged while passing through the indoor unit 106 indoors
are respectively formed.
[0007] The outdoor unit 104 is installed inside the case 102
positioned at the outdoor side. The outdoor unit is composed of: an
outdoor heat exchanger 120 connected to a compressor 116 by a
refrigerant pipe thus to be heat-exchanged with the outdoor air;
and an axial fan 122 opposite to the outdoor heat exchanger 120 for
generating a blowing force to suck the outdoor air and thus to
discharge it to the outdoor heat exchanger 120.
[0008] The case 102 positioned at the outdoor side is provided with
a shroud 126 where the axial fan and the outdoor heat exchanger are
mounted. The shroud 126 is provided with an orifice 128 for guiding
air to the axial fan 122 for a smooth suction.
[0009] The indoor unit 106 is composed of: an indoor heat exchanger
130 installed inside the case 102 positioned at the indoor side and
connected to the compressor 116 by a refrigerant pipe 124 thus to
be heat-exchanged with the indoor air; and a centrifugal fan 132
opposite to the indoor heat exchanger 130 for generating a blowing
force to suck the indoor air and thus to discharge it to the indoor
heat exchanger 130.
[0010] An orifice 134 for guiding the air that has passed through
the indoor heat exchanger 130 to the centrifugal fan 132 is formed
between the indoor heat exchanger 130 and the centrifugal fan 132.
An air guide 136 for guiding the air that has passed through the
centrifugal fan 132 to the indoor air discharge port 114 is
installed at the upper side of the centrifugal fan 132.
[0011] A division plate 150 for dividing the outdoor unit 104 and
the indoor unit 106 is installed inside the case 102, and a driving
motor 152 for driving the centrifugal fan 132 and the axial fan 122
is mounted at the division plate 150.
[0012] Operation of the window type air conditioner in accordance
with the conventional art will be explained in more detail. When a
power source is applied to the air conditioner, the compressor 116
and the driving motor 152 are driven thus to heat-exchange the
outdoor air at the outdoor unit 104 and to heat-exchange the indoor
air at the indoor unit 106.
[0013] More specifically, when the axial fan 122 is driven, the
outdoor air is sucked through the outdoor air suction port 108 thus
to be heat-exchanged while passing through the outdoor heat
exchanger 120. Then, the outdoor air is discharged outdoors through
the outdoor air discharge port 110.
[0014] When the centrifugal fan 132 is driven, the indoor air is
sucked through the indoor air suction port 112 thus to be cooled
while passing through the indoor heat exchanger 130. Then, the
indoor air is discharged indoors through the indoor air discharge
port 114.
[0015] However, in the conventional window type air conditioner,
the outdoor air suction port 108 is formed at both lateral surfaces
of the case 102, the outdoor air discharge port 110 is formed at
the front surface of the case 102, and the axial fan 122 of a great
air volume having a low flow path resistance is used to blow the
outdoor air. According to this, a comparatively wide suction space
has to be obtained in order to reduce the flow path resistance of
the outdoor air suction port 108 and the outdoor air discharge port
110, so that the size of the air conditioner is increased.
DISCLOSURE
[0016] Therefore, it is an object of the present invention to
provide a window type air conditioner capable of preventing an air
volume lowering due to a flow path resistance by applying a
centrifugal fan at an outdoor unit and capable of minimizing the

[0032] An indoor air suction port 12 for sucking the indoor air and
an indoor air discharge port 14 for discharging the air that has
been heat-exchanged while passing through the indoor unit 20
indoors are separately formed up and down at the front surface of
the case 10 positioned at the indoor side. Also, an outdoor air

[0033] The indoor unit 20 is composed of: an indoor heat exchanger
22 for passing the indoor air and thereby cooling; and an indoor
centrifugal fan 24 opposite to the indoor heat exchanger 22 and
connected to one side of the driving motor 44, for generating a

suction port 12 can pass through the indoor heat exchanger 22.
[0034] The indoor centrifugal fan 24 is mounted in a shroud 26, an
orifice 28 for a smooth air flow is formed between the indoor
centrifugal fan 24 and the indoor heat exchanger 22. An air guide
46 for guiding the air that has passed through the indoor

[0035] The outdoor unit 30 is composed of: an outdoor heat
exchanger 32 connected to the compressor by a refrigerant pipe 48
and heat-exchanged by the outdoor air; and an outdoor centrifugal
fan 34 opposite to the outdoor heat exchanger 32 and connected to

force to blow the outdoor air sucked into the outdoor air suction
port 16 to the outdoor heat exchanger 32.
[0036] A shroud 36 in which the indoor centrifugal fan 34 and the
indoor heat exchanger 32 are mounted is installed inside the case
10 positioned at the outdoor side. Also, an orifice 38 for smoothly
flowing the air sucked into the outdoor air suction port 16 to the

36.
[0037] The orifice 38 is provided with an air guide 50 for guiding
the air blown from the outdoor centrifugal fan 34 to the outdoor
heat exchanger 32.
[0038] The outdoor centrifugal fan 34 is a fan for constantly
maintaining a blowing force even if a flow channel resistance is
great, and is composed of: a hub 54 connected to the driving motor
44 by a rotational shaft 52; blades 56 formed at the outer side of
the hub in a circumferential direction with the same interval for
generating a blowing force; and a supporting ring 58 integrally
formed between the blades for supporting the blades.
[0039] FIG. 5 is a partial section view showing an outdoor unit of
a window type air conditioner according to another embodiment of
the present invention, and FIG. 6 is a frontal view showing an
outdoor centrifugal fan of the window type air conditioner
according to another embodiment of the present invention.
[0040] In the outdoor unit 30 of the window type air conditioner
according to another embodiment of the present invention, a
condensing water dispersing unit 70 for lifting condensing water
contained in the lower surface of the case 10 and thereby
dispersing to the outdoor heat exchanger 32 is formed at one side
of the outdoor centrifugal fan 34.
[0041] That is, the condensing water dispersing unit 70 is composed
of: a supporting rib 64 connected to the outer side of the outdoor
centrifugal fan 34 with a constant interval; and a dispersion ring
62 integrally connected to the end of the supporting rib 64 for
dispersing condensing water.
[0042] The dispersion ring 62 is formed as a circular ring type,
and the outer side surface thereof is in contact with the
condensing water thus to be rotated with the centrifugal fan 34
when the centrifugal fan 34 is rotated, thereby dispersing
condensing water to the outdoor heat exchanger 32.
[0043] As another embodiment of the condensing water dispersing
unit 70, the condensing water dispersing unit 70 may be composed of
a dispersion ring of a ring shape respectively connected to edges
of the blades 56 by a connection rib.
[0044] Operation of the window type air conditioner according to
the present invention will be explained as follows.
[0045] When a power source is applied to the air conditioner, the
compressor is driven thus to circulate a refrigerant and to drive
the indoor centrifugal fan and the outdoor centrifugal fan.
[0046] At this time, the indoor unit 20 is operated as follows. As
the indoor centrifugal fan 24 is driven, the indoor air is sucked
into the case 10 positioned at the indoor side through the indoor
air suction port 12 formed at the lower side of the front surface
of the case 10 thus to be cooled while passing through the indoor
heat exchanger 22. The cooled air is guided by the air guide 46
thus to be discharged to indoors through the indoor air discharge
port 14 formed at the upper side of the front side of the case
10.
[0047] Also, the outdoor unit 30 is operated as follows. As the
outdoor centrifugal fan 34 is driven, the indoor air is sucked into
the case 10 positioned at the outdoor side through the outdoor air
suction port 16 formed at both lateral surfaces of the case 10 thus
to be heat-exchanged while passing through the outdoor heat
exchanger 32. The heat-exchanged air is discharged to outdoors
through the outdoor air discharge port 18 formed at the rear side
of the case 10.
[0048] Herein, since the outdoor centrifugal fan 34 is applied to
the outdoor unit 30 in the same manner that the indoor centrifugal
fan 24 is applied to the indoor unit 20, an air volume lowering can
be prevented even if a flow channel resistance is increased.
According to this, a suction space into which the outdoor air is
sucked is reduced thereby to reduce the entire size of the
compressor.
[0049] In case that the condensing water dispersing unit 70 is
applied to the outdoor centrifugal fan 34, condensing water is
generated on the surface of the outdoor heat exchanger 32 by a
temperature difference. The condensing water falls down thus to be
collected into the lower portion of the case 10. Then the
condensing water is dispersed to the outdoor heat exchanger 32 by
the condensing water dispersing unit 70 thereby to lover the
temperature of the outdoor heat exchanger 32.
[0050] That is, when the outdoor centrifugal fan 34 is rotated, the
dispersion ring 62 connected to the outdoor centrifugal fan 34 by
the supporting ring 64 is together rotated thereby to lift up the
condensing water contained in the lower portion of the case 10 and
to disperse to the outdoor heat exchanger 32.
[0051] In the window type air conditioner according to the present
invention, the indoor centrifugal fan that the air volume is not
lowered even if the flow channel resistance is increased is
installed at the outdoor unit. According to this, the suction space
inside the case positioned at the outdoor side to which the outdoor
air is sucked is reduced thereby to reduce the entire size of the
compressor.
[0052] Also, the dispersion ring is installed at the outdoor
centrifugal fan thus to disperse condensing water to the outdoor
heat exchanger. According to this, the temperature of the outdoor
heat exchanger is lowered faster thus to enhance the function of
the air conditioner.
[0053] It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention
without departing from the spirit or scope of the invention. Thus,
it is intended that the present invention cover modifications and
variations of this invention provided they come within the scope of
the appended claims and their equivalents.
