[specific embodiment]
For making purpose of the present invention, scheme and beneficial effect more cheer and bright, the invention will be further described below in conjunction with accompanying drawing and preferred embodiment.What at first need to be explained is, " cyclone " that the present invention says only refers to be similar on the mode of appearance air-flow that the rotation of natural cyclone is risen, but not natural cyclone truly.
A kind of smoke exhaust ventilator embodiment that the present invention proposes, as illustrated in Figures 5 and 6, this smoke exhaust ventilator comprises blower fan system and two air inlets that are connected with this blower fan system respectively.Further, this smoke exhaust ventilator also comprises two cyclone generation devices 1 that are arranged at respectively two air inlet belows.Cyclone generation device 1 is used for the flow direction with the common steering current of blower fan system, and then produces the cyclone air-flow of the air inlet that flows to this cyclone generation device 1 top.Particularly, blower fan system is used for producing negative pressuren zone at the air inlet near zone, and then steering current flows to air inlet; Cyclone generation device 1 then for generation of the rotation air channel, and makes described negative pressuren zone move down along this air channel, near oil smoke sources such as cookers.As seen, although used " cyclone generation device " this expression, but cyclone is to produce under the acting in conjunction of cyclone generation device 1 and blower fan system, and " cyclone generation device " only is the expression of an image, fully by himself still being not enough to produce the cyclone effect.
The concrete structure of cyclone generation device 1 is as described in Fig. 1 to 4, and cyclone generation device 1 comprises open tubular column body 2 and four the first jet-impingement sections 3.Open tubular column body 2 is that the bottom surface is the cylinder of annulus.Four the first jet-impingement sections 3 are arranged on the inwall of open tubular column body 2 equably along the longitudinal extension direction of open tubular column body 2.The first jet-impingement section 3 is used for the inwall jet-stream wind to open tubular column body 2.The direction of the first jet-impingement section 3 jet-stream winds, tangent with the inwall of adjacent open tubular column body 2.The direction of the first jet-impingement section 3 jet-stream winds, also perpendicular with the longitudinal extension direction of open tubular column body 2.The longitudinal extension direction of described open tubular column body 2 namely is the short transverse of open tubular column body 2.Because under the use state, the longitudinal extension perpendicular direction of open tubular column body 2 is in stove panel, therefore, the direction of the first jet-impingement section 3 jet-stream winds is parallel to stove panel.The direction of four the first jet-impingement section 3 jet-stream winds is clockwise.The height h of open tubular column body 2 is 0.3m.The inner circle radius r of the bottom surface annulus of open tubular column body 2 is 0.2m.The thickness t of the bottom surface annulus of open tubular column body 2 is 0.1m.The shape of four the first jet-impingement sections 3 and size are identical.Each first jet-impingement section 3 all is column structure, and comprises an end face, is provided with several jet-impingement holes on this end face.These jet-impingement holes are used for the inwall jet-stream wind to described open tubular column body.Each first jet-impingement section 3 includes the curved surface that smoothly extends to the outer of described end face from the inwall of described open tubular column body.Under the use state, the cyclone air-flow of generation can pass the space that the inwall of open tubular column body 2 surrounds, and then flows to the air inlet that is positioned at these open tubular column body 2 tops.
As shown in Figures 1 to 3, each cyclone generation device 1 all also comprises four the second jet-impingement sections 4, and these four the second jet-impingement sections 4 are uniformly distributed on the upper bottom surface of open tubular column body 2.Fig. 3 is the top view of looking down from the top of the second jet-impingement section 4.Four the second jet-impingement sections 4 are used for jet-stream wind jointly, and then form gas curtain between the edge of the upper bottom surface of open tubular column body 2 and corresponding air inlet.The bottom of each second jet-impingement section 4 all is connected with the upper bottom surface of open tubular column body 2; The top of each second jet-impingement section 4 all is connected in the exhaust fume collecting hood of smoke exhaust ventilator.Place around corresponding air inlet on the top of four the second jet-impingement sections 4.The direction of the air-flow that each second jet-impingement section 4 sprays is and points to along clockwise direction the second adjacent jet-impingement section 4.As seen, the air-flow that the first jet-impingement section 3 and the second jet-impingement section 4 spray in the horizontal direction move towards identical, help like this to promote running efficiency, also help to reduce noise.Further, four the second jet-impingement sections 4 are corresponding one by one with four the first jet-impingement sections 3, and the second jet-impingement section 4 closes on its corresponding first jet-impingement section 3 and arranges.With regard to present embodiment, four the second jet-impingement sections 4 all are rectangular structure.
Shown in Fig. 2 and 4, cyclone generation device 1 also comprises the 3rd jet-impingement section 5.Fig. 4 is the upward view that the below from the 3rd jet-impingement section 5 looks up.The 3rd jet-impingement section 5 is used for jet-stream wind, and then forms gas curtain between the bottom surface of open tubular column body 2 and stove panel.The 3rd jet-impingement section 5 is arranged on the bottom surface of open tubular column body 2.The 3rd jet-impingement section 5 adopts integrally formed structure with open tubular column body 2.The first jet-impingement section 3 and the 3rd jet-impingement section 5 adopt same air supply system air feed.The air-flow that the 3rd jet-impingement section 5 and the first jet-impingement section 3 spray in the horizontal direction move towards identical, be along clockwise direction.
Below only be the preferred embodiments of the present invention, some technical characterictic is made amendment and replaced the embodiment that can also obtain other.As, the bottom surface of open tubular column body can not be annulus also, such as can also be interior edge for circle, outer be the ring of regular polygon.For another example, four air-flow trends in the horizontal direction that the first jet-impingement section sprays also can be counterclockwise.For another example, the inwall of open tubular column body can also adopt streamlined structure.For another example, the direction of the air-flow that each second jet-impingement section sprays also can be in the counterclockwise direction and point to the second adjacent jet-impingement section.For another example, the air-flow trend in the horizontal direction that the 3rd jet-impingement section sprays also can be in the counterclockwise direction.For another example, the second jet-impingement section also can adopt cylinder or other structures.For another example, also can adopt integrally formed technique to make the second jet-impingement section and open tubular column body.For another example, the first jet-impingement section and the second jet-impingement section also can adopt same air supply system air feed.
Need annotatedly to be, the present invention should not be understood to only limit to embodiment described above, but should be understood to cover claim of the present invention in conjunction with the specification disclosure definite all possible performance.Therefore, every content that does not break away from technical solution of the present invention to any simple modification, equivalent variations and modification that above embodiment does, all belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
