Referring to fig. 1, an embodiment of a ducted air conditioner 1000 of the present invention includes the blower assembly 100 of the above embodiment. The utility model discloses tuber pipe machine 1000 adopts the fan subassembly 100 of the first aspect embodiment, and fan subassembly 100 is through setting up the drive shaft 140 including first pivot 141, second pivot 142 and shaft connecting piece 143, thereby drive shaft 140 connects respectively motor 110 and bearing frame 120 drive and is located a plurality of wind wheels 130 synchronous rotations of motor 110's the same end. Wherein, between first pivot 141 and the axle connecting piece 143, all realize being connected through the grafting cooperation of erection column and mounting groove between second pivot 142 and the axle connecting piece 143, thereby set up the position of spacing restriction grafting moreover on the erection column. Therefore, the first rotating shaft 141 and the shaft connecting piece 143 can be ensured to be arranged in place quickly, the shaft connecting piece 143 and the second rotating shaft 142 can be arranged in place quickly, the shaft connecting piece 143 is arranged and fastened, and the assembly difficulty of workers is reduced. The embodiment of the utility model provides an in, bearing frame 120 is connected more firmly with second pivot 142, prevents that second pivot 142 from deviating from bearing frame 120, has promoted the security of tuber pipe machine 1000 transportation to the stability of tuber pipe machine 1000 operation has been improved.

The embodiment of the utility model provides an in, the grafting cooperation through erection column and mounting groove realizes being connected between axle connecting piece 143 and first pivot 141 and the second pivot 142, avoids using the screw to fix, can improve workman's assembly efficiency, also avoids having the risk that the screw skidded among the after-sales repair process moreover, has improved tuber pipe machine 1000 after-sales maintenance efficiency, has promoted user experience.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
