  • the partition 40 is provided between the fan motor assembly and the various devices for the refrigerant flow except the heat exchanger 25. That is, the inner space of the outdoor unit 10 is partitioned into a blowing region in which the fan motor assembly is installed and a device region in which the various devices for the refrigerant flow except the heat exchanger 25 are installed.
  • the control box 60 is seated on an upper end of the partition 40.

  • a lower end portion of the motor support 351 is bent forwardly in a " ⁇ "-shape (i.e., a right angle) with a predetermined length.
  • a receiving part 352 for receiving the coupling part 564 of the base pan 56 and a receiving hole 353 for receiving the guide part 565 of the base pan 56 are provided on/in the lower end portion of the motor support 351.
  • the receiving part 352 is formed in a front direction with a shape corresponding to that of the coupling part 564.
  • the receiving hole 353 has a diamond shape having a section width that widens from both side end portions thereof toward a central portion.
  • a coupling hole 360 is defined at a position corresponding to that of the coupling hole 566 of the coupling part 564 in the receiving part 352 overlapping with the coupling part 564 in front and rear directions in a state where the motor fixing part 35 is coupled to the base pan 56.
  • a motor coupling part 354 for coupling the motor 33 is disposed at a central portion of the motor support 351.
  • the motor fixing part 35 includes an electric wire guide part 350 for guiding an electric wire connected to the motor 33.
  • the electric wire guide part 350 includes an electric wire receiving part 355 for receiving the electric wire for supplying a power source to the motor 33, an electric wire hooking part 356 for hooking the electric wire, and an electric wire fixing part 357 for fixing the electric wire.
  • the electric wire guide part 350 is provided on the frame of the motor fixing part 35 having a " ⁇ "-shape (i.e., a squared-off "C"-shape) in section.
  • the electric wire receiving part 355 is provided inside the electric wire guide part 350.
  • the electric wire receiving part 355 is opened in a direction opposite to that of the heat exchanger 25.
  • a portion of the frame of the motor fixing part 35 is recessed in a direction in which the electric wire is bent to form the electric wire hooking part 356.
  • One end of the frame of the motor fixing part 35 extends to form the electric wire fixing part 357.
  • the electric wire fixing part 357 has a width greater than that of the electric wire receiving part 355.
  • a portion connecting the electric wire fixing part 357 to the frame of the motor fixing part 35 is slender such that the electric wire fixing part 367 is easily bent.
  • the electric wire fixing part 357 may be bent in a direction of the electric wire receiving part 355 to shield a portion of the electric wire receiving part 355.
  • the heat exchanger fixture 358 extends from an upper end of the motor support 351 toward a rear direction. An end portion of the heat exchanger fixture 358 is bent downwardly in a " ⁇ "-shape (i.e., a right angle) such that the heat exchanger 25 is not spaced a distance greater than a previously set distance from the motor fixing part 35.
  • the top surface case support 359 extends from the upper end of the motor support 351 toward a front direction. An end portion of the top surface case support 359 is bent in a " ⁇ "-shape (i.e., a right angle) such that the end portion of the top surface case support 359 is coupled to the front surface case 51 in a state where the front surface case (See reference numeral 51 of FIG. 2 ), the base pan 56, and the motor fixing part 35 are coupled to each other.
  • the motor fixing part 35 is easily coupled to the base pan 56.
  • the guide part 565 when the guide part 565 is in contact with a portion of the receiving hole 353, the guide part 565 is automatically guided toward a center of the receiving hole 353 due to interference between the guide part 565 and the receiving hole 353. That is, since the coupling part 564 of the motor support 351 and the coupling part 564 of the base pan 56 are smoothly guided up to a position overlapping with each other by the guide part 565 and the receiving hole 353, the coupling operation may be further facilitated. In detail, since the coupling hole 566 of the coupling part 565 and the coupling hole 360 of the receiving part 352 are correspondingly guided in the front and rear directions, the coupling operation may be further facilitated.
  • the electric wire is cleanly received and fixed, the appearance of the outdoor unit can be improved. In addition, it can prevent the electric wire from being caught on the rotating fan 31. Also, it can prevent the electric wire from being separated due to generation of a further larger tension when the electric wire is intended to be separated in a state where the electric wire is hooked on the electric wire hooking part 356. Thus, it can prevent the electric wire from being automatically separated from the electric wire hooking part 356. Since the electric wire receiving part 355 is opened in a fan direction, but a heat exchanger direction, a phenomenon in which the airflow is interrupted by the motor support 351 during the operation of the outdoor unit 10 can be minimized.
