Abstract
The utility model discloses a lampblack absorber with a secondary lampblack absorbing structure, which comprises an air outlet pipe assembly, an air outlet top board, a flue collecting hood and an outer cover, and is characterized in that a decorative cover is arranged on the outer cover, at least one opening is arranged on the lateral side of the decorative cover, and at least one air inlet is opened on the air outlet top board. When in work, flue floating on the upper portion of the flue collecting hood can be exhausted in second time through the opening on the lateral side and the air inlet on the air outlet top board, and thereby increasing wind quantity and reducing noise simultaneously.
Description
Technical field
The utility model relates to a kind of range hood, particularly a kind of range hood with secondary smoke pumping structure.
Background technology
Range hood has become one of requisite machine for kitchen use equipment of average family now, and existing range hood generally all is made up of discharge pipe assembly, air outlet top board, exhaust fume collecting hood assembly and blower hood etc.In fact, range hood always can escape around exhaust fume collecting hood by some oil smoke, and the shortcoming of this range hood maximum is flown away in the oil smoke of exhaust fume collecting hood top after being to absorb escape in the course of the work.
Summary of the invention
Technical problem to be solved in the utility model provides and a kind ofly can absorb the range hood that flies away after the escape in exhaust fume collecting hood top oil smoke.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this has the range hood of secondary smoke pumping structure, comprise discharge pipe assembly, air outlet top board, exhaust fume collecting hood assembly and blower hood, it is characterized in that being provided with cover of upholstery in described blower hood upper end, described cover of upholstery sidewall is provided with at least one opening, has at least one air inlet on the described air outlet top board.
Can there be passage to link to each other between described opening and the described air inlet,, also can connects such as both being connected with pipe.
In order to strengthen oil suction cigarette ability, described air inlet is positioned at polygon ABCDEF, wherein, AF hands over snail tongue projection line HF in a F, line segment AF and line segment EF are vertically intersected on a F simultaneously, line segment AB and BC are in respectively on the outer contour IB and BJ of air outlet top board, line segment EF and line segment HDE are on the air outlet outline line, line segment CD and line segment HE are vertically intersected on a D, line segment CD and line segment BJ are vertically intersected on a C, IB: BJ: HE: AB: BC: CD: DE=357: 300: 150: 187: 200: 147: 86.The reason that described air inlet will be positioned at polygon ABCDEF is: if opening reaches the left side of straight line AF, the air-flow of coming in from above so collides in this fierceness with the part air-flow of coming in from below, can cause noise to improve greatly this moment, and the ability of simultaneously top oil suction cigarette also will weaken.If opening reaches more than the straight line CD, this position is distant from the distance of spiral case air inlet, does not have the effect of oil suction cigarette basically, also can weaken following oil suction cigarette ability simultaneously, causes oil smoke to escape.
In order to reach better oil suction cigarette effect, described air inlet is positioned at rectangle ABKL, and its mid point L is positioned on the line segment AF, and some K is positioned on the line segment BC LA: AB=99: 187.Its reason is in polygon ABCDEF scope, aperture area is big more, its air quantity is big more, little to its noise effect, but can cause oil suction cigarette ability drop below the range hood, the situation that oil smoke is escaped will appear, add consideration to its structure, so preferably air inlet is positioned at rectangle ABKL, simultaneously again can guarantee the effect of secondary oil suction cigarette to the almost not influence of following oil suction cigarette this moment.
Described air inlet can be a geometry arbitrarily, such as square, circular, rhombus or the like, is preferably rectangle MNOL, and its mid point M is positioned on the line segment AF, and some O is positioned on the line segment LK MN: ML: AL=179: 91: 99.
Opening on the described cover of upholstery side can be a geometry arbitrarily, such as square, circular, rhombus or the like, is preferably rectangle.
Compared with prior art, advantage of the present utility model is to take away the soot gas that remains in the lampblack absorber top, can increase air quantity simultaneously, reduces noise.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Range hood in the present embodiment with secondary smoke pumping structure, comprise discharge pipe assembly 1, air outlet top board 2, exhaust fume collecting hood assembly 3 and blower hood 4, be provided with cover of upholstery 5 in described blower hood 4 upper ends, respectively have two rectangular apertures 6 at the left and right sides of described cover of upholstery 5 wall, the front side has three rectangular apertures 6, have an air inlet 7 on the described air outlet top board 2, this air inlet 7 is rectangle MNOL, described air inlet 7 is positioned at polygon ABCDEF scope, simultaneously in rectangle ABKL, AF hands over snail tongue 8 projection line HF in a F, line segment AF and line segment EF are vertically intersected on a F simultaneously, line segment AB and BC are in respectively on the outer contour IB and BJ of air outlet top board, line segment EF and line segment HDE are on air outlet 9 outline lines, line segment CD and line segment HE are vertically intersected on a D, line segment CD and line segment BJ are vertically intersected on a C, point M is positioned on the line segment AF, point O is positioned on the line segment LK, and IB: BJ: HE: AB: BC: CD: DE: AL: MN: ML=357: 300: 150: 187: 200: 147: 86: 99: 179: 91.
