Abstract

A turbo fan includes a main board and a suction ring installed on the main board and opposite to the main board. The suction ring has a plurality of receiving sections. A plurality of vanes are inserted between the main plate and the suction ring, each vane having an engagement portion engaged with one of the plurality of receiving portions to fix the suction ring to the plurality of vanes.

Description

technical field [0001] The present invention relates to a turbo fan used in, for example, an air conditioner and a method of manufacturing the turbo fan. Background technique [0002] Figure 6 A door unit 16 of an air conditioner to be installed into the ceiling is depicted. As shown, the door unit 16 has an air supply circuit or air circulation path, which includes an air inlet portion 17, an air filter (not shown), a heat exchanger (not shown), a turbo fan (not shown) and A plurality of air outlet portions 18 through which air passes through the above-mentioned components in sequence. The turbofan is drivingly connected to an electric motor (not shown). [0003] Fig. 7 depicts a conventional turbofan 1, which includes: a hub 2 located at the center of the turbofan 1 for firmly accommodating the rotating shaft of the electric motor therein; and a main plate 5 having an angular conical portion 3 and a generally flat annular plate 4. The conical portion 3 extends obliquel...
