Problems solved by technology

[0002] The vortex fan of the general commercial air conditioner with 3.5 hp and 5 hp indoor unit four-vent ceiling embedded indoor air conditioner, when installing, the fan is assembled on the motor shaft 4 through the injection hole 3, the elastic rubber 2, and the sleeve iron ring 1 , because the elastic rubber 2 is between the injection hole and the sleeve iron ring 1, there is a degree of freedom in the fan, and when it rotates, it jumps a lot, which will easily cause it to rub against the air inlet, produce abnormal noise, and affect the life of the fan. The existence of abnormal noise directly affects the sales of commercial air conditioners, and it is urgent to improve the fan installation structure of indoor air conditioners

Embodiment Construction

[0011] The structure for preventing the degree of freedom in the installation of the fan of the air conditioner indoor unit of the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 2 As shown, in the production of the fan, the annular bushing 5 is placed in the injection hole 3. During installation, the annular bushing is fixed with the motor shaft 4, and fixed with screws on the top of the fan. Since the annular bushing 5 is connected by two annular sleeves of the same height inside and outside and the reinforcing rib provided in the middle, and the diameter of the inner ring sleeve of the annular bushing 5 is slightly smaller than the diameter of the motor rotating shaft 4, such The installation restricts the freedom of rotation of the fan, making the fan run smoothly, thereby reducing the running noise, reducing the friction probability between the fan and the air inlet, and prolonging the service lif...

Abstract

The present invention provides a structure capable of preventing installed air conditioner indoor unit fan from generating freedom. The structure includes fan with molded installing hole, fan motor with rotating shaft and ring shaft sleeve set between molded installing hole and the rotating motor shaft. The ring shaft sleeve consists of two connected ring sleeves with reinforcing ribs and has inner sleeve with diameter smaller than diameter of the rotating shaft of the motor. The present invention installs ring shaft sleeve similar to rolling beaming inside the molded fan hole and the installs the motor shaft via the shaft sleeve so as to control the freedom of the fan for smooth rotation, low noise and less friction between the fan and the air inlet.

Description

technical field [0001] The invention relates to an air conditioner indoor unit, in particular to a structure for preventing freedom from being installed by a fan of the air conditioner indoor unit. Background technique [0002] The vortex fan of the general commercial air conditioner with 3.5 hp and 5 hp indoor unit four-vent ceiling embedded indoor air conditioner, when installing, the fan is assembled on the motor shaft 4 through the injection hole 3, the elastic rubber 2, and the sleeve iron ring 1 , because the elastic rubber 2 is between the injection hole and the sleeve iron ring 1, there is a degree of freedom in the fan, and when it rotates, it jumps a lot, which will easily cause it to rub against the air inlet, produce abnormal noise, and affect the life of the fan. The existence of abnormal noise directly affects the sales of commercial air conditioners, and it is urgent to improve the fan installation structure of indoor air conditioners.
