Abstract
The invention relates to an indoor fan structure of an integral air conditioner. The indoor fan structure comprises a spiral casing, an impeller, a fan electric motor and an electric motor support, wherein one side of the spiral casing, where the fan electric motor is fixed is provided with a separable spiral casing cover, the spiral casing cover is fixed between the spiral casing and the electric motor support; an air admission hole is formed on the spiral casing cover, the diameter of the air admission hole is smaller than that of the impeller; a through-hole of which diameter is larger than that of the impeller is formed on the spiral casing and opposite to the spiral casing cover; and when the spiral casing cover and the spiral casing are separated, the impeller can be placed in the spiral casing or taken out of the spiral casing through the through-hole so that the installation and replacement of the impeller are more convenient and the assembly or disassembly of the entire fan can be avoided. The hub in the impeller of the invention is nearer the fan electric motor side, thus the electric motor shaft between the hub and the fan electric motor becomes shorter, shorter transmission distance is adopted between the hub and the fan electric motor, the moment of the force of the electric motor shaft is reduced during rotation, the possibility that the electric motor shaft shakes in operation is reduced, and the normal operation of the indoor fan is ensured.
