  FIG. 7 is an exploded perspective view of the compressor sound insulation box 16 accommodating the compressor 18. As shown in FIG. 7, the compressor 18 is housed in the compressor sound insulation box 16. The compressor sound insulation box 16 is a box body such as a square pole configured by the sound insulation box sheet metal 17a to 17f. Of the sound insulation box metal plates 17a to 17f, a sound insulation box drainage hole 20 for draining condensation water generated around the compressor 18 is formed in the sound insulation box metal plate 17f on the bottom surface. Further, sound absorbing materials 19a to 19e such as sound absorbing felts are attached to the inner surfaces of the soundproof box metal plates 17a to 17e which are the side surfaces and the upper surface. The compressor 18 is disposed in the machine room 5 in a state housed in the compressor sound insulation box 16.

  FIG. 8 is a perspective view showing the sound insulation box metal plate 17 f attached to the inside of the outdoor unit 1. As shown in FIG. 8, the sound insulation box sheet metal 17 f is disposed so that the sound insulation box drainage hole 20 is positioned immediately above the recess 12 on the upper surface of the base sheet metal 2, and is fixed to the protrusion 13. The sound insulation box drainage hole 20 discharges the condensed water generated in the compressor sound insulation box 16 toward the drainage path 14. The drainage path 14 allows the drained condensation water to flow and reaches the base drainage hole 22 located at the lowermost part of the electric equipment room 4.

  FIG. 9 is a partial enlarged view showing a joint portion of the third partition plate 9 of FIG. As shown in FIG. 9, the third partition plate 9 is joined to the base sheet metal 2 at the lower end of the third partition plate 9 to partition the electric component room 4 and the machine room 5. The lower end of the third partition plate 9 is joined to the convex portion 13 of the base sheet metal 2 to form a drainage path 14 with the adjacent concave portion 12 and allow the drainage path 14 to reach the base drainage hole 22 of the electric room 4. As described above, the machine room 5 accommodating the compressor 18 communicates the soundproof box drainage hole 20 at the lower part of the compressor sound insulation box 16 with the base drainage hole 22 by the drainage path 14, through the base drainage hole 22. It communicates with the outside. Then, the condensed water discharged from the sound insulation box drainage hole 20 reaches the base drainage hole 22 from the sound insulation box drainage hole 20 through the drainage path 14 and is discharged to the outside of the outdoor unit 1.

  Subsequently, the operation of the outdoor unit 1 will be described. When the operation of the outdoor unit 1 is started, the control device accommodated in the electric component room 4 starts the process. Thereby, the compressor 18 of the machine room 5 and the blower of the blower room 3 start operation, and the refrigerant of the refrigerant circuit starts to flow. The blower blows air toward the air heat exchanger. The compressor 18 compresses the low temperature low pressure refrigerant that has flowed in, generates a high temperature high pressure refrigerant, and discharges it from the refrigerant piping. Such an operation is continued while the outdoor unit 1 is in operation.

  At this time, the compressor 18 generates a sound by driving, and generates condensed water around a pipe through which a low temperature refrigerant flows. Condensed water flows downward around the compressor 18 and the piping and reaches the bottom of the compressor sound insulation box 16. Condensed water flows out from the sound insulation box drainage hole 20 formed on the bottom surface of the compressor sound insulation box 16 and falls into the recess 12 of the base sheet metal 2 located immediately below. Condensed water is guided to the electric-component room 4 separated from the machine room 5 by the third partition plate 9 by the drainage path 14 formed by the recess 12. Then, it reaches the base drainage hole 22 disposed in the electric equipment room 4 and is discharged to the outside of the machine.

  On the other hand, the sound generated by the compressor 18 collides with the soundproof box metal plates 17a to 17f of the compressor soundproof box 16 in which the compressor 18 is accommodated. The sound that collides with the sound insulation box metal plates 17a to 17e is absorbed by the sound absorbing members 19a to 19e and disappears. In addition, the sound that collides with the sound insulation box sheet metal 17 f not provided with the sound absorbing materials 19 a to 19 e leaks from the sound insulation box drainage hole 20 to the base sheet metal 2. The sound is blocked by the plurality of concave portions 12 and convex portions 13 formed in the base sheet metal 2 and disappears soon.

  Furthermore, air flows through the second vent 11 provided in the electric component room 4 by the driving of the blower of the fan chamber 3 adjacent to the electric component room 4. When the air flows out from the second ventilation port 11, the air is taken in from the first ventilation port 10, and the air flows in the air passage C formed by the third partition plate 9. As a result, air flowing in the air passage C can flow in the vicinity of the upper surface of the second partition plate 8 to cool the electrical product that generates heat by driving.

  Thus, it has a two-layer structure in which a space is formed between the base sheet metal 2 having the plurality of concave portions 12 and the convex portions 13 and the compressor sound insulation box 16. Thereby, the condensation water generated around the compressor 18 can be made to flow out of the sound insulation box drainage hole 20 and be discharged to the outside from the base drainage hole 22 through the drainage path 14. Further, the sound generated by the compressor 18 is absorbed by the sound absorbing members 19a to 19e of the compressor sound insulation box 16, and the sound leaked from the sound insulation box drainage hole 20 is a drainage path formed by the plurality of concave portions 12 and convex portions 13. It is reflected and absorbed by 14 and disappears, and no sound leaks to the outside. Furthermore, since the air passage C is formed by the third partition plate 9 which separates the machine room 5 and the electric equipment room 4, the electricity of the electric room 4 can be leaked from the first vent 10 for taking in air. The goods can be cooled.

  According to the outdoor unit 1 according to the present embodiment described above, the electric product room is formed in the second partition plate 8 perpendicular to the first partition plate 7 that partitions the housing 1 a, and the second partition plate 8 is perpendicular The third partition plate 9 forms a machine room 5 in which the compressor 18 is accommodated. The machine room 5 is a closed structure having no path communicating directly with the outside, and the sound of the compressor 18 does not leak out, and the condensation water generated around the compressor 18 drains the drainage path 14 of the base plate 2. It circulates and reaches the base drainage hole 22. In addition, air flows through the air passage C formed in the electric-equipment room 4 by the first ventilation port 10 and the second ventilation port 11, and the electric-equipment is cooled. Thus, drainage of condensed water and cooling of electrical components can be sufficiently performed, and noise can be prevented from leaking out through the opening provided in the outdoor unit 1.

  The air passage C is formed from the first ventilation port 10 below the second partition 8 to the second ventilation port 11 above the second partition 8 so that the electrical components can be efficiently cooled. Can.

  An air passage C formed from the first ventilation port 10 to the second ventilation port 11 passes through a notch 8 a formed in the second partition plate 8 and circulates.

  The sound leaked from the sound insulation box drainage hole 20 is absorbed by the side surface of the drainage path 14 or transmitted in a direction extending in the direction of the side surface along the drainage path 14 and muffled, so that it reaches the base drainage hole 22 It is difficult to do.

  The condensed water flowing through the drainage path 14 can pass through the gap of the recess 12 between the third partition plate 9 and the base plate 2 to reach the base drainage hole 22 and flow out.

  The compressor sound insulation box 16 accommodating the compressor 18 is provided with the sound insulation box drainage hole 20 from which the condensation water generated in the compressor 18 is discharged and the sound absorbing members 19a to 19e for absorbing sound, so the base drainage Noise does not leak from the holes 22 and condensation water can be discharged.

  Since the compressor sound insulation box 16 is fixed to the convex portion 13 of the base sheet metal 2, the condensation water dropped from the compressor sound insulation box 16 into the drainage path 14 is a recess between the compressor sound insulation box 16 and the base sheet metal 2. It can leak from 12

  Condensed water generated in the compressor sound insulation box 16 can fall into the drainage path 14 and can flow from the space between the compressor sound insulation box 16 and the base sheet metal 2 through the drainage path 14 and flow out to the outside of the compressor sound insulation box 16 .

  The sound leaked from the sound insulation box drainage hole 20 does not reach the base drainage hole 22 directly from the sound insulation box drainage hole 20, but hits the wall of the drainage path 14 interposed halfway before reaching the base drainage hole 22 It is muted.

  Since the electrical component chamber 4 accommodates the electrical component and the machine chamber 5 accommodates the compressor, the compressor 18 can be soundproofed and the electrical component can be cooled.
