Abstract
The invention discloses a motor for a dust collector. The motor comprises an air inlet positioned on a motor housing, and a movable inducer, a stationary inducer and a motor body which are arranged in the motor housing and sequentially distributed below the air inlet. The motor is characterized in that: a silencing hood made from a silencing material is arranged between the periphery of the stationary inducer and the inner wall of the motor housing; and simultaneously, a silencing partition board made from the silencing material is arranged between the stationary inducer and the motor body. The motor for the dust collector has low cost and good noise reduction effects.
Description
Technical field
The present invention relates to a kind of motor of dust collector.
Background technology
In the 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 make an effort from motor itself, obtain to export than low noise by when guaranteeing its operating efficiency, reducing power consumption, yet 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 by setting up the structures such as anechoic chamber, wind-guiding pipeline, its shortcoming is to cause the motor housing complex structural designs, the model manufacturing 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 motor of dust collector comprises the air inlet that is positioned on the motor housing, and is located at moving inducer, quiet inducer and the motor body that also is arranged in successively the air inlet below in the motor housing; It is characterized in that being provided with the silencer cover of being made by quieter material between described quiet inducer periphery and the motor housing inwall, be provided with the sound gobo of being made by quieter material between quiet inducer and the motor body simultaneously.
Further, sound gobo described in the present invention is clamped and fixed between quiet inducer and the motor body, has the hole that the rotating shaft of power supply machine body is stretched out on it.
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, described wind-guiding is provided with the silencer cover of being made by quieter material in the gap.
The same with routine techniques, moving inducer is fixed in the rotating shaft of motor body described in the present invention; Described quiet inducer and motor housing inwall are fixed.
Preferably, silencer cover described in the present invention in the form of a ring.
Preferably, the quieter material of silencer cover described in the present invention and sound gobo is the noise reduction sponge.
Operation principle of the present invention is as follows: after the motor of dust collector running, the passive inducer of outside air sucks in the air inlet, along the impeller clearance of moving inducer to discharging all around, enter at last the impeller clearance of quiet inducer by the wind-guiding gap between quiet inducer and the motor housing inwall, by motor body, discharge at the most backward motor housing rear portion subsequently.Owing to added silencer cover in the wind-guiding gap of the present invention between quiet inducer and motor housing inwall, simultaneously between quiet inducer and motor body, be provided with sound gobo, these two noise reduction parts can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby more effectively reduce motor noise.
Advantage of the present invention is:
1. this motor of dust collector provided by the invention, it is simple in structure compared to existing technology, and is easy to implement, and cost is low, and excellent noise reduction effect.
2. this motor of dust collector provided by the invention, it is compared, and increase noise reduction parts weaken outside the air-flow acoustic energy of flowing through herein in the simple wind-guiding gap between quiet inducer and motor housing inwall, also take into account simultaneously the noise reduction process of the air-flow between quiet inducer and the motor body of flowing through, more effectively raised noise reduction.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is half sectional view of the present invention (white arrow is the air-flow trend among the figure);
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; 7, sound gobo.
Embodiment
Embodiment: in conjunction with 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, described motor housing 1 is provided with air inlet 2, be fixed with moving inducer 3 in the rotating shaft of described motor body 6, described 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 by screw on motor housing 1 inwall.Grip the sound gobo 7 of being made by quieter material between described quiet inducer 4 and the motor body 6, have the hole that the rotating shaft of power supply machine body 6 is stretched out on this sound gobo 7.Described 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 5 of being made by quieter material in the described wind-guiding gap.Silencer cover described in the present embodiment 5 in the form of a ring, and the quieter material of described silencer cover 5 and sound gobo 7 is the noise reduction sponge.
Operation principle of the present invention is as follows: after the motor of dust collector running, the passive inducer 3 of outside air sucks in the air inlet 2, along the impeller clearance of moving inducer 3 to discharging all around, enter at last the impeller clearance of quiet inducer 4 by the wind-guiding gap between quiet inducer 4 and motor housing 1 inwall, by motor body 6, discharge at the most backward motor housing 1 rear portion subsequently.Owing to added silencer cover 5 in the wind-guiding gap of the present invention between quiet inducer 4 and motor housing 1 inwall, simultaneously between quiet inducer 4 and motor body 6, be provided with sound gobo 7, these two noise reduction parts can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby effectively reduce motor noise.
This motor of dust collector that present embodiment provides, compared to existing technology, it is simple in structure, and is easy to implement, and cost is low, and excellent noise reduction effect.
This motor of dust collector that present embodiment provides, it is compared, and increase noise reduction parts weaken outside the air-flow acoustic energy of flowing through herein in the simple wind-guiding gap between quiet inducer 4 and motor housing 1 inwall, also take into account simultaneously the noise reduction process of the air-flow between quiet inducer 4 and the motor body 6 of flowing through, more effectively raised noise reduction.
