Abstract
The invention discloses a de-noising structure of a dust collector motor. The structure comprises an air inlet positioned on a motor shell, and a dynamic wind guide wheel and a static wind guide wheel which are arranged in the motor shell and sequentially arranged below the air inlet. The structure is characterized in that: a silencing hood made of silencing material is arranged between the periphery of the static wind guide wheel and the inner wall of the motor shell. Compared with the prior art, the structure is simple and easy to implement, and has low cost and good de-noising effect.
Description
Technical field
the present invention relates to a kind of noise reduction structure of motor of vacuum cleaner.
Background technology
In
prior art in order to solve the noise problem of motor of dust collector; Each producer usually summarize take following two kinds by way of; A kind of is to work hard from motor itself; Obtain than low noise output through when guaranteeing its operating efficiency, reducing power consumption, however this by way of cost higher, and actual noise reduction is not satisfactory; Another kind of then be that air-guiding aisle to motor housing inside improves; For example improve the shape of dynamic and static inducer, perhaps cut down noise through setting up structures such as anechoic chamber, wind-guiding pipeline, its shortcoming is to cause the motor housing complex structural designs; The model manufacture difficulty increases, cost up.
Summary of the invention
the present invention seeks to: provide a kind of cost the low and noise reduction structure of motor of vacuum cleaner of excellent noise reduction effect.
technical scheme of the present invention is: a kind of noise reduction structure of motor of vacuum cleaner comprises the air inlet that is positioned on the motor housing, and is located at moving inducer and the quiet inducer that also is arranged in the air inlet below in the motor housing successively; It is characterized in that being provided with the silencer cover of processing by quieter material between said quiet inducer periphery and the motor housing inwall.
are the same with routine techniques, and motor body is installed in the motor housing described in the present invention, and said moving inducer is fixed in the motor body rotating shaft, and quiet inducer is fixed on the motor body.
are further, quiet inducer described in the present invention peripheral with the motor housing inwall between be provided with the wind-guiding gap that communicates with moving inducer impeller clearance, said wind-guiding is provided with the silencer cover of being processed by quieter material in the gap.
are preferred, and silencer cover described in the present invention in the form of a ring.
are preferred, and quieter material described in the present invention is the noise reduction sponge.
operation principle of the present invention is following: after the motor of dust collector running; The passive inducer of outside air sucks in the air inlet;, discharge to the motor rear portion to discharging all around along the impeller clearance of moving inducer through the last impeller clearance that gets into quiet inducer, the wind-guiding gap between quiet inducer and the motor housing inwall.Owing to added silencer cover in the wind-guiding gap of the present invention between quiet inducer and motor housing inwall, can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby effectively reduce motor noise.
Advantage of the present invention is:
the present invention compares prior art, and it is simple in structure, and is easy to implement, and cost is low, and excellent noise reduction effect.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is a half sectional view of the present invention;
Fig. 2 is the A-A view of Fig. 1.
wherein: 1, motor housing; 2, air inlet; 3, moving inducer; 4, quiet inducer; 5, silencer cover; 6, motor body.
The specific embodiment
embodiment: combine Fig. 1, shown in Figure 2; This noise reduction structure of motor of vacuum cleaner that present embodiment provides; Have motor housing 1 and the motor body 6 that is installed in the motor housing 1, said motor housing 1 is provided with air inlet 2, is fixed with moving inducer 3 in said motor body 6 rotating shafts; Said moving inducer 3 is positioned at air inlet 2 belows, and is fixed with the quiet inducer 4 that is positioned at moving inducer 3 belows on the motor body 6.Said moving inducer 3 all is positioned at motor housing 1 with quiet inducer 4.Said quiet inducer 4 peripheral with motor housing 1 inwall between be provided with the wind-guiding gap that communicates with moving inducer 3 impeller clearances, be provided with the silencer cover of processing by quieter material 5 in the said wind-guiding gap.In the present embodiment this silencer cover 5 in the form of a ring, and said quieter material is the noise reduction sponge.
operation principle of the present invention is following: after the motor of dust collector running; The passive inducer 3 of outside air sucks in the air inlet 2;, discharge to the motor rear portion to discharging all around along the impeller clearance of moving inducer 3 through the last impeller clearance that gets into quiet inducer 4, the wind-guiding gap between quiet inducer 4 and motor housing 1 inwall.Owing to added silencer cover 5 in the wind-guiding gap of the present invention between quiet inducer 4 and motor housing 1 inwall, can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby effectively reduce motor noise.
the present invention compares prior art, and it is simple in structure, and is easy to implement, and cost is low, and excellent noise reduction effect.
the foregoing description certainly only are explanation technical conceive of the present invention and characteristics, and its purpose is to let the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
