Electric machine rotational axis inserted hole anti deforming, loosening and releasing structure of moisture removing device fan leaf

Abstract

The invention relates to a moisture separator fan sphere, in particular to a deforming-proof and loose-proof tripping mechanism for a motor rotary axis of the moisture separator fan sphere, resolving the question that the prior moisture separator fan sheets are easy to deform and loose as the motor rotary axis heating or with high rotary speed with low intensity material. The art scheme of resolving the question comprises a shaded-pole motor fixed on a motor holder plate and a centrifugal fan sheet inserted to the rotary axis end of the shaded-pole motor via a rotary axis inserting hole, characterized in that the rotary axis inserting hole is injected with a polygonal groove which is inserted with a polygonal metal collar with same peripheral size with the groove, wherein the center of the collar is designed to be the rotary axis inserting hole and is used in fixing the fan motor axis with the sheet in moisture separator or other electric appliances.

Description

technical field [0001] The invention relates to the technical field of dehumidifiers and fans, in particular to a motor rotating shaft of a fan blade of a dehumidifier that can prevent the motor rotating shaft of the fan blade motor from being deformed due to high speed of the motor shaft due to heat generation and even tripped from the rotating shaft. Anti-deformation, loosening and tripping structure of socket hole. Background technique [0002] Generally speaking, the dehumidifier introduces the humid air in the room into the inside of its case, and lowers the temperature of the heat exchanger composed of the evaporator and the condenser through which the refrigerant flows, so that the moisture in the humid air is condensed out and then dehumidified. The air is discharged into the room to achieve the purpose of reducing indoor humidity. [0003] As shown in Figure 1 and Figure 2, the dehumidifier made by prior technology mainly includes the front air intake 52, and the c...

Problems solved by technology

[0015] However, as mentioned above, due to the thinner motor shaft of the cover machine, the larger centrifugal fan blades and the lower material strength of the fan blades in the existing dehumidifier fans, the long-used fan blade center motor rotation shaft insertion hole is used to receive the motor rotation shaft. The effect of heat and its rotational force will cause deformation, enlargement, loosening or even failure to be synchronously driven by the rotating shaft of the motor to rotate or trip
