<P>PROBLEM TO BE SOLVED: To provide a locking member for preventing the damage of a ventilation fan, which is caused by collision between a blowing fan on a suction opening side and a bell-mouth and by the rolling of the end side of a longer rotary shaft of a fan motor during transportation in the vertically two-stage structured blowing fan of a ceiling cassette type air conditioner. <P>SOLUTION: This ceiling cassette type air condition includes a blowing fan 5 including a hub to which the rotary shaft of the fan motor is connected, a shroud having a center suction opening facing the hub, partition panels for vertically partitioning the hub and the shroud into two stages, i. e. the internal diameter face of the shroud as an inlet side and an area between the outer diameter of the shroud and the outer diameter of the hub as the outlet side, and a plurality of blades positioned between the hub and the partition panels and between the shroud and the partition panels, respectively, and a bell-mouth 7 whose outlet end is inserted in the suction opening in a case body mounted on a ceiling face. In packing the case body, a locking member 12 for controlling the movement of the blowing fan is placed between the bell-mouth and the blowing fan on the suction opening side. <P>COPYRIGHT: (C)2008,JPO&INPIT |
