  • FIGS. 9 and 10 schematically show longitudinal sectional views of an integral type air conditioner according to the present invention.
  • FIG. 9 shows the operation when an air cleaning function is not being performed.
  • FIG. 10 shows the operation when the air cleaning function is being performed.
  • the left and right fan motors 450 rotate the left indoor fan 420 and the right indoor fan 460 .
  • the compressor 560 (see FIG. 4 ) circulates work fluid through the heat exchange cycle.
  • the indoor fan 420 uses the centrifugal fan thereby effectively using the indoor space.
  • the outdoor fan 460 uses an axial fan in order to increase an air flow.
  • Driving the indoor fan 420 at the left and right sides causes indoor air to be taken in through the front intake part 210 and through the indoor heat exchanger 400 .
  • the air which is heat-exchanged to a relatively low temperature in the indoor heat exchanger 400 is taken into the indoor fan 420 .
  • the air then discharges in the circumference direction of the indoor fan.
  • the centrifugal fan of the indoor fan 420 can be applied, and the indoor fan 420 may be a turbo fan so as to increase airflow.
  • the air discharged in the circumference direction of the indoor fan 420 is guided along the air guide 300 . Additionally, the air guide 300 guides discharged air during air purification operations.
  • the stepping motor 356 rotates, thereby moving a rear portion of the passage guide plate 354 in an upward direction which opens the front of the discharge passage 352 and closes a bottom surface of the filter mounting part 360 .
  • the air forcibly ventilated by the indoor fan 420 does not flow into the high performance filter 370 . Instead, the air discharges to the front via the discharge passage 352 through the discharge part 220 .
  • the discharge door 230 moves in a downward direction as shown, thereby opening the discharge part 220 .
  • the solid line arrows depict the operation states of the discharge door 230 and the passage guide plate 354 . Additionally, the block arrows depict the airflow when the air purifying function is not being performed.
  • the air conditioner of the present invention purifies air will now be described.
  • the stepping motor 356 moves the rear end of the passage guide plate 354 in a downward direction.
  • the passage guide plate 354 shields the discharge passage 352 such that air forcibly blown from the indoor fan 420 flows into the lower surface of the filter mounting part 360 as shown in FIG. 10 .
  • the high performance filter 370 purifies air introduced into the internal space of the filter mounting part 360 from the bottom as the air passes through the high performance filter 370 .
  • the purified air discharges to the top through the filter grill 740 .
  • the discharge door 230 moves to the top as shown in FIG. 9 thereby shielding the discharge part 220 since air is not discharged to the front through the discharge passage 352 .
  • the outdoor fan 460 causes the intake of outdoor air into the air conditioner.
  • the rotation of the outdoor fan 460 causes an inflow of external air into the air conditioner through the side intake hole 720 and the upper intake hole 730 of the cabinet 700 .
  • the air introduced into the air conditioner by the outdoor fan 460 is guided along the shroud 500 .
  • heat exchange occurs between the air discharged to the rear by the outdoor fan 460 and the work fluid of the heat exchange cycle while passing through the outdoor heat exchanger 550 .
  • hot air of the work fluid is transmitted to the discharge air for discharge outdoors.
  • air introduced into the inside of the air conditioner having a relatively low temperature in the room temperature state is via an outer circumference of the compressor 560 .
  • the air disposed about the outer circumference of the compressor 560 lowers the temperature of the compressor 560 .
  • the fan motor 450 couples at a rear surface of the lower air guide with a separate bracket (not shown). However, the fan motor 450 may couple with the air conditioner using any suitable method. To further illustrate, the fan motor 450 may be coupled directly to the air guide. In detail, only the driving shaft of the fan motor is not inserted into the lower air guide. Instead, the entire body of the fan motor 450 can be inserted into the lower air guide and mounted.
  • a frame may be installed at a front surface of the front panel 200 thereby enhancing an appearance of the integral type air conditioner.
  • a flat display panel for instance, a LCD monitor or a PDP panel may be installed in at a vacant space of the front surface of the front panel 200 for use in displaying an electronic image, for use as a monitor or for use as a television.
  • the compressor is installed at the center portion of the integral type air conditioner which increases the portability of the air conditioner of the present invention.
  • the outdoor fan 460 includes two separate units, i.e., one pair, the compressor is not necessarily placed there between. More specifically, although the compressor is placed at any one side of the outdoor construction in the embodiments shown above, heat exchange efficiency in accordance with the present invention may be enhanced if blowing occurs throughout the entire area of the heat exchanger.
  • the grill is not formed at the front side of the front panel. Therefore, internal parts of the present invention are not exposed to an exterior. In addition, since the discharge door of the present invention shields the indoor discharge hole when the air conditioner is not in use, the present invention enhances the appearance of the front side of the air conditioner.
  • the present invention enhances an image of an air conditioner.
  • the present invention does not include a related-art grill, the front panel does become contaminated from foreign particles which accumulate on an intake hole or the discharge hole of the grill.
  • the present invention facilitates cleaning of an air conditioner and a front panel of the air conditioner.
  • the discharge door shields the indoor discharge hole. Therefore, foreign particles are prevented from penetrating through the discharge hole and contamination of the front panel is prevented.
