While the air direction is deflected by the air direction deflecting plate 53, the air is sent again from the blowout port 52 into the room by the blower 2.

  A drain pan 6 is provided below the heat exchanger 4, and condensed water dripped from the heat exchanger 4 is received by the drain pan 6 and then discharged to the outside. A decorative panel 5 is mounted outside the bell mouth 21 and below the drain pan 6, and an electrical component 3 is provided between the bell mouth 21 and the inner peripheral edge of the decorative panel 5. 2. Electric power is supplied to the float switch 12, the drain pump 13, the motor 56 for the wind direction deflector 53, and the like.

  As shown in FIG. 2 and FIGS. 3 (A) to 3 (C), the drain pan 6 has a drain port 61 for discharging drain water during maintenance, and a seal for sealing the drain port 61. A drain cap 7 is provided.

  On the side surface of the corner portion near the drain cap 7 on the inner peripheral edge of the decorative panel 5, a second wiring port 55 for optional wiring as shown in FIGS. A wiring path is formed inside the second wiring port 55.

  As shown in FIG. 2, the second wiring port 55 for optional wiring is provided with a drain pump 13 in the vicinity of the corner portion of the decorative panel 5, for example, an air cleaning unit (not shown), an air filter cleaning unit, Alternatively, when optional equipment such as an introduction unit for introducing fresh air is installed, these optional wirings are used to lead out toward the electrical equipment section 3.

  Further, when the optional device is not installed, the second wiring port 55 for the optional wiring is closed so that erroneous wiring such as wiring other than the optional device can be surely prevented at the location. It is necessary to keep.

  As shown in FIG. 2, for example, a light receiving unit (not shown) that receives driving information from a remote controller, on the side surface of the corner of the inner peripheral edge of the decorative panel 5 that forms a diagonal line with the second wiring port 55 for optional wiring, A first wiring port 54 for wiring for the display unit 11 for displaying operation information is provided, and a wiring path is formed inside the first wiring port 54. In such a case, the corner cover 57 having the same shape may be erroneously attached in the vicinity of the second wiring port 55 for option wiring having a similar shape. This is because the length of the wiring for guiding is insufficient, so that it is not necessary to notice that the wiring is mistakenly attached for the first time.

  The light receiving unit and the display unit 11 are configured to be provided in one corner cover 57, and when the corner cover 57 is attached to the corner part of the decorative panel 5, the light receiving part and the display unit 11 are led to the electrical component 3 due to different attachment positions.
