している。 In Fig. 1, reference numeral 1 indicates a ceiling-embedded air conditioner, in which indoor air is sucked from an air-conditioned room 2 through an air suction port 4 fixed in a decorative panel 3, and passes through a multi-blade centrifugal blower 5 to a heat exchanger. The air heat-exchanged in step 6 is discharged from an air discharge port 7 to air-condition the room. The blower electric motor 8 penetrates through the cabinet top surface 9, protrudes into the attic space 10, and is locked to the cabinet top surface 9.

る。 With the above configuration, the multi-blade centrifugal blower 5 has the blowing motor 8 located higher than the conventional example, so the air guider 11 on the suction side can be provided larger on the motor side, and the suction air Fan efficiency can be increased by reducing flow path resistance. Further, the blower electric motor 8 has a cooling fan (not shown) inside, and by rotating the cooling fan as the blower electric motor 8 operates, the attic air can be circulated inside the electric motor.
The cooling effect of the electric motor can be significantly improved compared to the conventional method.
