Benefits of technology

0016] The first objective of the present invention is to obtain a bell-mouth shape having excellent blower characteristics, and to mount the electrical parts into the

Problems solved by technology

Therefore, only the decorative panel that possesses the suction inlet and the blower outlet is exposed from the ceiling panels, that is, the enclosures of the ceiling cassette type air conditioners are embedded above the ceiling panels of the room to be air conditioned, and the inhabitants do not receive the sense of oppression at all, so there is a tendency of their usage increasing.
Hitherto, there were problems related to arrangement of electrical parts box against the aforementioned bell-mouth and mounting structure of the electrical parts that are accommodated in the electrical parts box.
As a result, the electrical parts-box becomes big-sized, and it hinders the miniaturization of the unit.
In this way, whether it is bell-mouth Ba or Bb,
