The specific embodiment
Below, the vacuum cleaner of describing the electric machine assembly of non-limiting example with reference to the accompanying drawings and comprising this electric machine assembly according to the present invention.See figures.1.and.2, electric machine assembly 100 can comprise for example motor, inner housing 120 and the shell body 130 of induced-draught electric motor 110.Induced-draught electric motor 110 can be configured to produce suction and arrange vertically with respect to dust-absorbing element 10.Induced-draught electric motor 110 can comprise that the exhaust window 110a that is formed on its following circumference is to pass through this exhaust window discharged air.The air that is inhaled into by the first passage 121a can leave from induced-draught electric motor 110 by exhaust window 110a.
Induced-draught electric motor 110 can comprise the high output motor of the revolutions per minute (RPM) that can produce high numerical value.Like this, induced-draught electric motor can produce vibration.For in the vertical direction (preferably relative with loading direction) supports induced-draught electric motor and prevents vibration, supporting member 140 can be set.Supporting member 140 can be arranged on the core of inner housing 120.Supporting member 140 can be made by rubber, to prevent vibration when supporting induced-draught electric motor 110.Supporting member 140 can be that about 20mm is to about 40mm.
The dust bag (not shown) and the cyclone dust-collecting apparatus (not shown) that can be used as dust-collector can be set near air intake duct 11.The air of isolating dust in dust-collector can flow through the first passage 121a after by air intake duct 11.
Second inner housing 122 can be suitable for surrounding not at least a portion of the lower part of the induced-draught electric motor 110 that is surrounded by first inner housing 121.Second inner housing 122 also can comprise the second passage 122b that is formed on its circumference, to exhaust air to diffusion admittance P1.
First inner housing 121 and second inner housing 122 are removably secured to one another.In this non-restrictive example, they utilize first securing member (for example bolt) 20 fastened.Certainly, also have other fastening method of for example hinged fastening or interference fit, these are other non-limiting examples that are considered to be within the purview.
Can relatively form the 3rd passage 130a with the second passage 122b.Therefore, the air that leaves by the second passage 122b can not flow directly into the 3rd passage 130a.Air can change into according to circumferencial direction and rotating along diffusion admittance P1, leaves by the 3rd passage 130a then.Like this, air-flow direction can be changed, thereby noise can be reduced.Blast pipe 12 can be adjacent to arrange, thereby can promptly be discharged from the air that the 3rd passage 130a leaves with the 3rd passage 130a.
It is secured to one another that first shell body 131 and second shell body 132 can be dismantled ground.In this non-limiting example, second securing member (for example bolt) 30 can be used to fix first shell body 131 and second shell body 132.Certainly, also have other fastening method of for example hinged fastening and interference fit, these are considered to be in the non-limiting example in the scope of the invention.
With reference to Fig. 2 and Fig. 3, diffusion admittance P1 can be formed between inner housing 120 and the shell body 130 with diffused air.More particularly, diffusion admittance P1 can be the space that is formed by shell body 130 and inner housing 120, and has the average cross section that increases gradually along air-flow direction.
Describe diffusion admittance P1 in detail with reference to Fig. 3 and Fig. 4.Fig. 3 is the electric machine assembly when watching and the viewgraph of cross-section of dust-absorbing element, Fig. 4 be illustrate Fig. 3 point 1., 2., 3., 4., 5., 6., 7., the curve map that changes of the cross section of the diffusion admittance P1 that 8. locates.
With reference to Fig. 3 and Fig. 4, the point that the cross section of diffusion admittance P1 is positioned at from the second passage 122b 1., the point that flows along diffusion admittance P1 of air 2., 3., 4., 5. and the point that is positioned at of the 3rd passage 130a 6., 7., 8. repeat brokenly to increase and reduce towards the point that is discharged into blast pipe 12 (see figure 2)s by the air that leaves from the 3rd passage 130a, this is illustrated by the broken lines in the curve map of Fig. 4.Yet 8. 1. average as can be seen cross section increase to point gradually from point.The change of average cross-section is represented by solid line.
Certainly, 8. 1. the cross section of diffusion admittance P1 preferably increase to point regularly from point.Yet, in this non-limiting example, when diffusion admittance P1 has gradually the average cross-section that increases, can be configured to have the irregular cross section that increases and reduce of repeating.
The air that leaves as the exhaust window 110a from induced-draught electric motor 110 is during by diffusion admittance P1, the 3rd passage 130a and blast pipe 12, described air diffusion.Like this, air has flow velocity lentamente.In addition, the air that leaves from exhaust window 110a can spread along circumferencial direction, is discharged into diffusion admittance P1 by the second passage 122b then.Air can flow in diffusion admittance P1 along circumferencial direction in rotation, rises by the 3rd passage 130a when it, and when giving off from dust-absorbing element 10 by blast pipe 12 then, mobile direction can repeatedly change.
Because air velocity becomes slowly and air-flow direction changes, so reduced noise.Particularly, can reduce low-frequency band noise and peak value component effectively.With reference to Fig. 5 and Fig. 6, will describe noise in detail and reduce effect.Fig. 5 illustrates the curve map that the noise of being realized by electric machine assembly reduces effect, and Fig. 6 illustrates the curve map that the peak value component of being realized by electric machine assembly reduces effect.
If adopt electric machine assembly 100, then to compare with the situation that does not adopt electric machine assembly 100, noise reduces about 4.8dBA.(0～2000Hz) noise is significantly reduced at low frequency region.
Noise approximately reduces 9.0dBA in the position ' a ' that the first peak value component occurs, and the position ' b ' that occurs at the second peak value component approximately reduces 20dBA, and the position ' c ' that occurs at the 3rd peak value component approximately reduces 7.0dBA.Therefore, if compare, then adopt electric machine assembly 100 to improve the peak value component significantly with the situation that does not adopt electric machine assembly 100.
Below, with the air flow passage that is described in electric machine assembly 100 and the dust-absorbing element 10.With reference to Fig. 2 and Fig. 3, can descend along the inside of induced-draught electric motor 110 by the air intake duct 11 and the first passage 121a inhaled air, can leave from induced-draught electric motor 110 by exhaust window 110a then.
Can spread and be discharged into diffusion admittance P1 from exhaust window 110a air discharged by the second passage 122b.Air can flow along circumferencial direction in diffusion admittance P1, leaves from diffusion admittance P1 by the 3rd passage 130a then.The air that leaves by the 3rd passage 130a can be vertical rising leave from blast pipe 12 then.
Aforesaid according to the present invention non-limiting example electric machine assembly 100 and have in the vacuum cleaner of this electric machine assembly 100, air is by diffusion in the second passage 122b, diffusion admittance P1, the 3rd passage 130a and the blast pipe 12, and therefore described air has slowly flow velocity and changes on direction.Therefore, can reduce the whole grade of noise.Especially can reduce low-frequency band noise and peak value component effectively.Therefore, reduced widely to clean produced simultaneously noise at vacuum cleaner.
In addition,, and do not have extra noise absorption component,, and reduced its manufacturing cost so electric machine assembly 100 has simple structure because electric machine assembly 100 has the diffusion admittance P1 that forms between inner housing 120 and shell body 130.
The foregoing description and advantage only are exemplary, can not be construed to restriction the present invention.This instruction can easily be applied on the device of other type.In addition, the description purpose of the embodiment of the invention is illustrative, does not limit the scope of claim.A lot of replacements, modification and change are clearly to those skilled in the art, and are within the scope of the invention.
