  • the inlet passage 700 is provided to a space between the front frame 300 and the front panel 400. Since the front panels 400 are plurally provided, the inlet passages 700 are plurally provided in correspondence to forward/backward movements of the front panels 400.
  • the inlet passages 700 are provided to a middle part, an upper part, and a lower part of the space between the case 200 and the front panels 400 in correspondence to the movements of the front panels 400, respectively.
  • the inlet passages 700 are configured in a manner of diverging from the middle part of the space between the case 200 and the front panels 400 toward the upper and lower parts of the space. So, it is able to introduce a sufficient quantity of the indoor air into a space between the front panels 400.
  • the inlet passages 700 are configured to diverge upward and downward across the whole middle part (left end to right end) of the space between the case and the front panels 400 in correspondence to the movements of the front panels 400 and across the whole upper and lower parts (left end to right end) of the case 200.
  • both lateral sides of the space between the case 200 and the front panel 400 are preferably closed in case of a forward movement of the front panel 400.
  • the inlet passage 700 can be provided to a middle part and a lateral part of the space between the case 200 and the front panel 400 in correspondence to a forward/backward movement of the front panel 400.
  • the heat exchange passage 800 means a passage that induces heat exchange of an indoor air, which has been introduced into the case 200 via the inlet passage 700 and then passes through the heat exchanger 210 provided within the case 200.
  • the heat exchange passage 800 is configured by the front frame 300 in rear of the air inlet 320 and the case 200.
  • the heat exchanger 210 is vertically installed and the middle part of the heat exchanger 210 has the prescribed shape. So, the heat-exchanged air having been introduced from the front can be more smoothly blown in upward and downward slant directions.
  • the outlet passage 900 means a passage to blow the air, which has been air-conditioned via the heat exchange passage 800, into the indoor space again.
  • the outlet passage 900 is opened/closed by the outlet unit 600 provided to the upper and lower parts of the case 200. And, the outlet passage 900 is configured by the air outlet 620 constructed with the front frame 300 and the case 200 assembled together.
  • unexplained reference numbers 297, 523, 524, 1000, 1010, 1100, 1110, 1120, and 1150 in the drawings are a mounting hanger, a fixing projection, a hanging sill, an opening/closing guide, an insertion hole, a driving motor fixing part, a body, an accommodating part, and a loading leg, respectively.
  • the above-configured air conditioner according to the present invention is operated in a following manner.
  • a plurality of the separated front panels 400 are horizontally moved back and forth by the driving unit 500. And, indoor air is introduced into the case 200 via the air inlet 320 provided to the front side of the front frame 300 in correspondence to the movements of the front panels 400.
  • a plurality of the inlet passages 700 provided to the space between the front panels 400 and the front frame 300 play a role as a passage for introducing the indoor air into the air inlet 320.
  • the driving unit 500 includes the pinion gear 521 and the rack rail 522 connected to the front panel 400, the front panel 40 can be stably moved back and forth without fluctuation despite the intake flowing of the air.
  • the intake indoor air can be more smoothly blown out in upward and downward directions owing to the reduced flowing resistance within the heat exchange passage 800.
  • the outlet panel 610 is rotationally moved toward a front/rear of the case 200 to open/close the outlet passage 900. So, the outlet panel 610 can remove the user's unpleasantness by indirectly blowing warm air without interrupting front air introduction in case of heating operation.
  • the outlet unit 600 is elastically loaded by pressurizing and fixing the blowing fan bearing part 221 via the elastic piece 670. So, the locking members for supporting the bearing part 212 are reduced to facilitate air conditioner manufacturing.
  • a plurality of the dewdrop fall preventing recesses 611 are formed by cutting the backside of the outlet panel 610 to be spaced apart from each other in a horizontal direction. So, dewdrops are received in the dewdrop fall preventing recesses 611 and then evaporate, whereby an inner space can be maintained clean.
  • the dewdrop fall preventing recesses 611 are configured to gradually reduce their depths downwardly by considering a considerable quantity of dewdrops on the outlet panel 610 without weakening rigidity of the outlet panel 610 considerably.
  • a plurality of the drain guide rails 1800 are provided between the heat exchanger 210 and the drain pan 1700 along the backside of the case 200. And, the water splash preventing sill 1833 is rounded and projected below the drain hole 1811. Hence, the condensed water discharged via the drain hole 1811 of the upper drain guide rail 1830 can be prevented from being spread wide.
  • the present invention provides the following effects or advantages.
  • a quantity of indoor air for heat exchange can be sufficiently secured.
  • An installation height of an air conditioner is not considerably restricted. Even spreading of air blown in a cooling/heating operation can be induced.
  • a warm air can be indirectly discharged in a heating operation without interruption of front air introduction. And, a sufficient quantity of air can be sucked in via a plurality of air inlets.
  • a plurality of drain guide rails are arranged along a backside of a case between a heat exchanger and a drain pan. And, a water splash preventing sill is rounded and projected under a drain hole. So, a condensed water discharged from the drain hole of an upper drain guide rail is not spread wide.
  • an elastic piece provided to a bearing cover part of an outlet unit pressurizes and elastically fixes a blowing fan bearing unit thereto. So, a locking member for supporting the bearing unit is reduced to facilitate air conditioner manufacturing.
  • a plurality of dewdrop fall preventing recesses are formed by cutting a backside of an outlet panel to be spaced apart from each other in a horizontal direction. So, dewdrops are received in the dewdrop fall preventing recesses and then evaporate, whereby an inner space can be maintained clean.
