Abstract

The present invention relates to the field of air conditioners, in particular to a fan blade structure and an air conditioner with it, including fan blades and a motor. The motor has a protruding rotating shaft. The root is covered with a washer, and the rotating shaft and the rotating shaft sleeve are limited by the ball limit structure and the limit surface structure. There is a certain disassembly gap between the installation side of the fan blade and the washer on the motor. The present invention combines the traditional The screw fixing method between the fan blade and the rotating shaft is changed to a ball fixing method, which improves the assembly and disassembly efficiency, and the connection is firm, not easy to loosen, and will not cause noise. The "opening" on the outer blade affects the air volume and generates noise.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a fan blade structure and an air conditioner having the same. Background technique [0002] The air conditioner needs to drive the fan blades to rotate through the motor. The fixed structure of the traditional air conditioner cross-flow fan blade and the motor is to insert the motor shaft into the bushing on the cross-flow fan blade, and then set a screw on the outer wall of the bushing, and rotate the screw Fix the motor shaft in the shaft sleeve of the cross-flow fan blade. This method makes it necessary to rotate the screw during assembly and disassembly. The bushing of the cross-flow fan blade is generally inside the fan blade. In this way, when the screw is rotated, an opening for accommodating a screwdriver needs to be provided on the outer blade of the cross-flow fan blade. The open rotary screw makes the rotation time-consuming and laborious, which seriously affects the a...
