Abstract

The object of the present invention is to provide a turbofan which can improve the welding strength of ultrasonic welding compared with the turbofan of the prior art. In the turbo fan, a main board or a shroud having a plurality of welded fitting parts and the same number of blade parts as the plurality of welded fitting parts are respectively formed from thermoplastic resin, and then the main board or the shroud is welded by ultrasonic welding. The blade member is integrally assembled with the blade member, the welding fitting portion has a wall portion vertically formed around the blade member inserted into the welding fitting portion, and an inclined portion is provided on the inner side surface of the bottom portion; the blade member is inserted into the welding fitting portion. Ultrasonic welding is carried out with the main board or the shield in a state where the joint part is in contact with the inclined part.

Description

technical field [0001] The present invention relates to a turbo fan molded of thermoplastic resin mounted on an air conditioner, and relates to a turbo fan capable of achieving ideal welding strength. Background technique [0002] The turbofans in the prior art are manufactured through the following three methods. [0003] First, use thermoplastic resin to separately mold the main board and multiple blades into a fan body and shield, and then combine them by ultrasonic welding; [0004] Second, use thermoplastic resin to separately form the fan body and the main board with multiple blades on the back of the shield, and then combine them by ultrasonic welding; [0005] Thirdly, after the main board, the shield and multiple blades are individually molded with thermoplastic resin, they are combined by ultrasonic welding or the like. [0006] In each of the methods described above, the main plate or the shroud is provided with a fitting portion that engages with the blade memb...
