PROBLEM TO BE SOLVED: To improve working efficiency by safely handling a part of comparatively low voltage relating to a control signal, and a comparatively low driving voltage of an electric component box in a ceiling-embedded air conditioning indoor unit. SOLUTION: In a first area Ar1 of an electric component box 30, a group of electric components such as a dip switch 35 and a connector 36 to which only a low voltage of several volt and several tens of volt is supplied are disposed. In a second area Ar2 under an electric component box cover 31, a group of electric components such as a connector 63a of a terminal board 61 and a main printed circuit board 62 to which a high voltage of about 200 volt is supplied is disposed. Work can be performed on the group of electric components such as the dip switch 35 by inserting fingers from an opening 75 at a lower part of the first area Ar1. On the other hand, the work can safely be performed as the fingers cannot reach the electric components such as the terminal board 61 from the opening 75. COPYRIGHT: (C)2010,JPO&INPIT |
