FIG. 2 will be explained. In the figure, reference numeral 1 denotes an outdoor unit main body, which has a compressor chamber 4 at its right end that houses a compressor 8 and refrigerant piping (not shown). Further, the left end portion has an electrical component room 17 in which electrical components 9 are stored. Reference numeral 3 denotes a blower room, in which an axial fan 6 fixed to a fan motor 5 is disposed near the center of the upper, lower, left, and right sides. Compressor room 4 and electrical equipment room 1
7 and the blower room 3 are separated by a partition plate 2 made of sheet metal. This partition plate 2 is configured in a radial shape of a three-dimensional curved surface starting from the circular shape of the bell mouth portion 21 around the axial fan 6 and reaching a rectangular shape around the entire outer periphery of the flat heat exchanger 7. It is shaped like a cathode ray tube. Furthermore, this substantially cathode ray tube-shaped partition plate 2 is provided with a leg shielding plate 18 and an upper shielding plate 19, and partitions the compressor chamber 4 and the electrical component chamber 17. A fan motor 5 for driving an axial fan 6 is arranged near the center of a bell mouth section 21 on a motor support 20. The motor support 20 is fixed to a substantially cathode ray tube-shaped partition plate 2, and has a fan motor 5 disposed on the outlet side of the axial fan 6 and inserted into the boss of the axial fan 6.

な仕切板を設けることができる。In this embodiment, the air flow that passes through the suction port 13 and the heat exchanger 7 due to the rotation of the axial fan 6 is guided by the shape of the partition plate 2 while coming into contact with the partition plate 2, which is approximately in the shape of a cathode ray tube, to form an axial flow. After being sucked into the fan 6, it is blown out from the air outlet 14. Since the partition plate 2 is smoothly continuous from the entire surface of the heat exchanger 7 to the bell mouth part 21, the air flow is smoothly drawn in along this line. As mentioned above, turbulence and separation of the air flow at this time rarely occur. Therefore, the noise value related to aerodynamic performance can be reduced. In addition, since the substantially cathode ray tube-shaped partition plate 2 protrudes to the outer periphery of the bell mouth, the compressor room 4 and the electrical component room 1
The volume of 7 increases, and the storage capacity of each increases. Further, the leg shielding plate 18 and the upper shielding plate 19 provided on the partition plate 2 have the effect of insulating noise from the compressor room 8. Furthermore, since the main partition plate 2 is three-dimensionally constructed, it is not necessary to have a two-part structure of the right side partition plate and the left side partition plate, and an inexpensive partition plate can be provided.

The lattice 1 is guided along the flat panel 24 and on the left and right by the flat panel 24 and the inclined surfaces 23, 23a.
The air is blown out from the openings of the second blow-off ports 28 to 28c. On the other hand, in terms of safety, hands and fingers inserted into the openings of the second air outlets 28 to 28c are blocked by a protective net 27 provided at the first air outlet 14. Further, since the clearance between the inner circumferential portion of the protective net 27 and the flat panel 17 is small, fingers cannot be inserted therein, and safety against the rotation of the mixed flow fan 6 can be ensured.

The outdoor unit of an air conditioner according to claim 1 has an outdoor unit main body, and a partition plate that partitions the inside of the main body into a blower room that accommodates a heat exchanger and a blower and other rooms. Since the partition plate is formed in a radial shape of a three-dimensional curved surface starting from the outer periphery of the air outlet of the blower room and continuing to the outer periphery of the heat exchanger, turbulence does not occur in the air flow within the partition plate. This improves aerodynamics and reduces noise.
