[embodiment]
For making the object of the present invention, scheme and useful effect clearly understand, below in conjunction with accompanying drawing and preferred embodiment, the invention will be further described.
As shown in Fig. 1 to 5, a kind of smoke exhaust ventilator embodiment that the present invention proposes, comprises U-shaped cover 1, spiral case 2, exhaust duct sleeve 3 and air draft pipeline, and the upper wall of U-shaped cover 1 is provided with out air port, and spiral case 2 is installed and is arranged in U-shaped cover 1. Spiral case 2 comprises front baffle plate 7, rear deflector door 8 and coaming plate 9, and front baffle plate 7 and rear deflector door 8 are symmetricly set in the both sides of coaming plate 9, and front baffle plate 7 is provided with intake opening.The lower end of exhaust duct sleeve 3 is rectangular configuration, the upper end of exhaust duct sleeve 3 is circular configuration, being connected with the curved-surface structure 6 seamlessly transitted between rectangular configuration end 4 and circular configuration end 5, rectangular configuration end 4 is connected with the air port that goes out of U-shaped cover 1, and circular configuration end 5 is connected with air draft pipeline. Specifically, curved-surface structure 6 adopts streamlined structure. Curved-surface structure 6 entirety is in tilting, and the slope trend of curved-surface structure 6 is consistent at the slope trend going out air port place with spiral case 2.
Adopting this smoke exhaust ventilator of plane cutting, two portions that coaming plate 9 obtains after cutting are symmetrical, and two portions that exhaust duct sleeve 3 obtains after cutting are also symmetrical, and Fig. 1 is the sectional view being connected with rear deflector door 8 obtained after cutting. Consider the constructional feature of coaming plate 9 self, if making two portions that coaming plate 9 obtains after cutting symmetrical, can only longitudinally cutting, and cutting mode is unique. On the sectional view being connected with rear deflector door 8 that smoke exhaust ventilator obtains after cutting (i.e. accompanying drawing 1), angle between the section in the left side of curved-surface structure 6 and line segment AB is α, 90 ° of > α > 0 °, line segment AB is the line segment being on above-mentioned sectional view, line segment AB is on the upper surface of the upper wall of U-shaped cover 1, and line segment AB is between the section of the left and right sides of curved-surface structure 6. And the section in the left side of curved-surface structure 6 is parallel with the section on the right side of curved-surface structure 6. What need to be explained here is, owing to curved-surface structure 6 is thinner, the section of the section in the left side of curved-surface structure 6 and right side is all considered as a line segment by the present embodiment, in actually operating, if the thickness of curved-surface structure 6 need to be considered, then α gets the angle between the longitudinal cenlerline (or edge line of longitudinal direction) of the section in the left side of curved-surface structure 6 and line segment AB, if this specification sheets elsewhere is not particularly illustrated, then the section in left side and the section on right side to curved-surface structure 6 does identical understanding. What smoke exhaust ventilator obtained after plane cutting is connected with on the sectional view of rear deflector door 8 (i.e. accompanying drawing 1), angle between the section of the left end of coaming plate 9 and line segment AB is β, 180 ° of > β > 90 °, the section of the right-hand member of coaming plate 9 is corresponding to snail tongue 10 place. 180 ° of > alpha+betas. What need to be explained here is, owing to coaming plate 9 is thinner, the section of the left end of coaming plate 9 is considered as a line segment by the present embodiment, in actually operating, if the thickness of coaming plate 9 need to be considered, then β gets the angle between the longitudinal cenlerline (or edge line of longitudinal direction) of the section of the left end of coaming plate 9 and line segment AB, if this specification sheets elsewhere is not particularly illustrated, then the section of the left end of coaming plate 9 is done identical understanding.
Through a large amount of tests, and find after testing data is carried out the researching and analysing of system: when α gets 66 °, when β gets 104 °, the working efficiency of smoke exhaust ventilator is the highest, and noise is minimum.
The via area of rectangular configuration end 4 is roughly equal with the via area of circular configuration end 5.
Below it is only the preferred embodiments of the present invention, some technology feature is modified and replaces the embodiment that can also obtain other. As, the via area of rectangular configuration end 4 is set to be less than the via area of circular configuration end.
Needing additional instruction, the present invention should not be understood to be only limitted to enforcement mode described above, but should be understood to cover all possible performance that the claims in the present invention are determined in conjunction with specification sheets disclosure. Therefore, every content not departing from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to the technical spirit of the present invention, all belongs to the protection domain of technical solution of the present invention.
