Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Referring to Fig. 1～Fig. 4, a kind of range hood, including fan shroud 1 and the main air blower 2 being arranged in fan shroud 1, it is just
In the structure in fan shroud 1 is clearly illustrated, part fan cover 1 is only shown in Fig. 1.
In the present embodiment, main air blower 2 adopts the air inlet 24 of horizontal type centrifugal blower, i.e. main air blower 2 to be vertically oriented to lower section,
Its structure is identical with conventional centrifugal blower, including the electricity of spiral case 21, the impeller 22 in spiral case 21 and driving impeller 22
Machine 23.The air outlet of the spiral case 21 of main air blower 2 is provided with outlet housing 3.
Eddy flow bucket 4 and blowing cover 5 are just provided with to the lower section of the air inlet 24 of main air blower 2.Eddy flow bucket 4 include staving 41,
At least two first accessory fans 42 and blowing post 43 corresponding with the first accessory fan 42, the upper and lower opening of staving 41 is in simultaneously
It is hollow.In the present embodiment, it is realization preferably uniform air-supply effect, the first accessory fan 42 is four, equably, is spaced
It is arranged in around the top of staving 41.Blowing the upper and lower opening of post 43 and be in it is hollow, the top of staving 41 offers through hole 44, blows
The upper end of wind post 43 connects with the air outlet of the first accessory fan 42, and blowing post 43 is entered in staving 41 through after through hole 44.
Blowing partially vertically the extending downwardly in staving 41 of post 43.At least one blowhole is offered on the side wall of blowing post 43
431, blowhole 431 causes inside and outside (inside the staving 41) connection of blowing post 43.Preferably, blowhole 431 be two or
It is more, along the blowing in the vertical direction arranged for interval of post 43.The direction of the blowhole 431 on each blowing post 43 and staving 41
The wall tangential direction of side wall be respectively formed identical angle [alpha], it is preferred that α is 20 °～30 °, is consequently formed the effect that rotation is blown.
Preferably, the first accessory fan 42 is Small Centrifugal Fan.
Blowing cover 5 is nested in the bottom of staving 41, and blowing cover 5 includes postpartum mastitis fan housing 51 and interior blowing cover 52, postpartum mastitis fan housing
51 and interior blowing cover 52 hollow forms that are upper and lower opening.Postpartum mastitis fan housing 51 is set in the periphery of interior blowing cover 52, and postpartum mastitis
It is partially enclosed between the top of fan housing 51 and interior blowing cover 52.The bottom of postpartum mastitis fan housing 51 is radially outward horizontal-extending to form the
One flange 53, the bottom of interior blowing cover 52 is radially outward horizontal-extending to form the second flange 54, and the first flange 53 is turned over higher than second
Side 54.Interlayer is formed between postpartum mastitis fan housing 51 and interior blowing cover 52, folder is also formed between the first flange 53 and the second flange 54
Layer (the radial outer end opening of the interlayer), thus, two interlayers interconnect the flat air blasting passage 55 of composition.
Blowing cover 5 also includes at least two second accessory fans 56, is to realize preferably likewise, in the present embodiment
Uniform air-supply effect, the second accessory fan 56 is four, equably, arranged for interval dry outside cover 51 top around, the
The air outlet of two accessory fans 56 is communicated in the interlayer between postpartum mastitis fan housing 51 and interior blowing cover 52, thus, the second auxiliary wind
The air-flow of the blowout of machine 56 is outwards blown out by flat air blasting passage 55, produces flat blowing gas stream.Preferably, the second accessory fan 56 is little
Type centrifugal blower.
During work, the air inlet 24 of main air blower 1 produces the effect of prewhirling due to the rotation of impeller 22, has inlet air flow
Certain rotation；Eddy flow bucket 4 is made by four blowouts of blowing post 431 and the side wall of staving 41 flat blowing gas stream at an angle
Obtain and formed in staving 41 eddy flow, strengthen the effect of prewhirling of main air blower 1 so that negative pressure is extended downwardly in staving 41, soot gas energy
Enough entrances for faster sucking staving 41；Blowing cover 5 utilizes Aaberg exhaust hood principles, is produced by the second accessory fan 56
It is flat to blow jet, the induction flow field of this jet and the velocity profile superposition of blowing 5 under sheds of cover, further compression control
Region, so as to reach the purpose for increasing air-breathing speed and orientation air-breathing, so as to reach lifted the speed that is sucked of oil smoke air-flow and
The purpose of control oil smoke air-flow range of scatter, additionally, it is flat blow jet and also block blowing 5 lower section both sides clean airs of cover inhaled
Enter.Air current flow path can be found in Fig. 3 and Fig. 4 shown in arrow.
Thus, oil smoke just can effectively be accelerated by the combination of above-mentioned main air blower 1, eddy flow bucket 4 and blowing 5 three kinds of structures of cover
The speed of suction, and reach the purpose that control oil smoke lifts smoke absorption effect.
