After gear, can turn back and flow into described second air channel 32 through described transition air port 40, then discharging from described air outlet 28.Therefore
The wind that the setting of upper spacer 23 enables to through described exhaust fan 11 is discharged is buffered further, more can effective noise reduction function.
The position of the bottom surface of described face-piece 21 and described side-lens 25 opposite side is additionally provided with multiple projection 212, described on every
Plate 23 is connected by connecting portion 30 with described projection 212, and described lower clapboard 24 is connected to the lower end of described projection 212, passes through
The setting of described projection 212 can further enhance described upper spacer 23 and the structural strength of described lower clapboard 24, certainly at it
In his embodiment, it is also possible to be not provided with described projection 212.
Preferably, in this utility model, described perforate 211 is round hole, and described side-lens 25 is semicolumn wall-like, institute
Stating upper spacer 23 and described lower clapboard 24 is circular bulkheads, the diameter of described perforate 211 is more than the diameter of described upper spacer 23.When
The most in other embodiments, described perforate 211, side-lens 25, upper spacer 23 and lower clapboard 24 can also be other shapes, this reality
Being not limited thereto with novel, the most described perforate 211 is square or oval, and described upper spacer 23 and lower clapboard 24 are square
Or it is oval.
The end face of described face-piece 21 is additionally provided with at least one holding parts 213, is correspondingly provided with at least one fixing bottom described support 1
Groove 111, described exhaust hood 2 and described support 1 are by being immobilizated in described holding parts 213 in described holding slot 111 removably
Connect, therefore use long, described exhaust hood 2 can be removed from described support 1 and be carried out or change.
Next illustrate, wind motor process in air draft denoising structure of the present utility model, as shown in Figure 6, when
When motor (non-label) in support 1 works, exhaust fan 11 operates therewith, is inhaled by wind air inlet 10 bottom described support 1
Enter the space around motor, motor is lowered the temperature, then after exhaust fan 11 is discharged, enter institute by described perforate 211
Stating in the first air channel 31 of exhaust hood 2, then stream rushes described upper spacer 23, and after described upper spacer 23 is kept out, wind can be to described
The periphery of upper spacer 23 spreads rapidly, and a portion wind can flow out from described ventilation slot 26 and stream is punched in described lower clapboard 24
On, another part wind directly can flow into described second air channel 32 from described transition air port 40, and stream is punched on described lower clapboard 24
Wind after described side-lens 25 blocks, the transition air port 40 of described side-lens 25 offside can be flowed to and flow into from transition air port 40
To described second air channel 32, flowed out to outside described exhaust hood 2 by described air outlet 28 after then flowing through described second air channel 32.
In order to illustrate in greater detail the wind kinestate in this structure, take 6 sampled points the most in figure 6, respectively A,
A ', B, B ', C, D, A point is positioned at upper spacer 23 by air outlet 28 side, and A ' point is positioned at upper spacer 23 farthest away from air outlet 28 side, B
Point is positioned at lower clapboard 24 by air outlet 28 side, and B ' point is positioned at lower clapboard 24 farthest away from air outlet 28 side, and C point is positioned at the second air channel
32 by transition air port 40, and D point is positioned at the second air channel 32 by air outlet 28, wind entrance that described exhaust fan 11 is discharged described the
One air channel 31 arrives A point and A ' point, and then wind is from A point to B point, puts to B ' point from A ', and the wind of B point is stopped by described side-lens 25
After flow to B ' point, the wind that B ' puts flows to C point through transition air port 40, and the wind of C point has flowed to again D point, and the wind of last D point is through air outlet
28 flow out exhaust hood 2, and so, wind flows out the path shape of described exhaust hood 2 from described first air channel 31 through described second air channel 32
Shape is similar to the asymmetric "U" shaped of two-end-point.And motor run the heat produced also can flowing with the wind and leave support 1,
The heat radiation making food processor is achieved.
The air draft denoising structure of this utility model food processor is by arranging the first wind of mutually concatenation in exhaust hood 2
Road 31 and the second air channel 32 are to extend the length of air exhaust passage, additionally it is possible to effectively reduce the motor in exhaust fan 11 and support 1 high
The noise produced during speed operating, for the most schematically illustrating this measure, introduces a mathematical formulae helping to understand here
The calculating formula of air exhaust passage sound deadening capacity (this formula be):
WhereinFor noise along the attenuation of air exhaust passage length；
WhereinFor acoustic absorptivity, relevant with the material of composition air exhaust passage；
Wherein P is the perimeter of section of air exhaust passage；
Wherein S is the area of section of air exhaust passage；
WhereinLength for air exhaust passage.
Can be seen that from above-mentioned formula, it is assumed that the perimeter of section P of this utility model air exhaust passage and cutting of air exhaust passage
The ratio of face area S is little with the size difference of prior art, can put aside perimeter of section P's and area of section S here
The impact of ratio, does not the most consider the difference with prior art material, and noise is logical with air draft along the attenuation of air exhaust passage length
The length in road is directly proportional, therefore increases the length of air exhaust passage that is be effectively improved the noise attenuation along air exhaust passage length, from
And make the effect of noise reduction be obviously improved, the first air channel 31 and the second air channel of mutually concatenation it is provided with in this utility model increase
32, so make the air exhaust passage length in above-mentioned formula be extended significantly, noise is along the attenuation of air exhaust passage length
The biggest lifting, the noise that final exhaust fan 11 and motor produce when running up is effectively suppressed, as
The noise reduction of this food processor is realized further.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
Protection domain within.
