Abstract

The present invention discloses a structure for reducing resonace noise of fan case for vacuum cleaner motor. Said structure includes fan outer protector which is connected with front side opening position of outer shell of vacuum cleaner motor and can be used for protecting fan, diffuser placed on the peripheral surface of the fan and diffuser sealing surface which is connected together with fan outer protector, sectional extended space which is tightly fixed on the front face of diffusion vane formed into diffuser and can reduce flow rate of air high-speed flower out from the fan and resonace-resisting circular groove which is forward projected and formed on the above-mentioned diffuser sealing surface. In the vacuum cleaner provided by said invention the structure capable of reducing motor noise is adopted, so that its product reliability also can be raised.

Description

technical field [0001] The present invention relates to an invention of a vacuum cleaner, and more specifically, relates to a structure for reducing resonance noise of a fan casing for a vacuum cleaner motor. Background technique [0002] A vacuum cleaner is a device that collects external foreign matter such as inhaled dust inside. In order to generate suction, a motor is provided inside its body. Below, combine Figure 1 to Figure 3 , for a detailed description of an existing vacuum cleaner. [0003] figure 1 It is a half sectional view of a conventional vacuum cleaner motor. figure 2 yes figure 1 side view. image 3 It is a partial cross-sectional view of a fan housing for a conventional vacuum cleaner motor. [0004] Such as figure 1 , figure 2 , image 3 As shown, the motor 100 of the existing vacuum cleaner includes a motor housing 110 , a stator 140 , a rotor 130 , a motor shaft (not shown), a fan 170 , a diffuser 160 , variable speed guide vanes 150 , a...
