Abstract
The invention discloses a suction opening of a range hood, comprising a body having a suction opening connected to an exhaust system through a pipeline, a cover extended to the upside of the oil-smoke pollution source from the body, and an inner notch arranged on the cover relative to the oil-smoke source, wherein the suction opening is arranged on the lateral wall of the inner notch and partially covers the lateral top of the oil-smoke pollution source, and the sectional shape of the inner notch is matched with the maximum sectional shape of the oil-smoke pollution source. Because a cover extends forwards at the suction opening, the distance between the suction opening and the oil-smoke pollution source becomes smaller to reduce the escaping of the oil and smoke, therefore, the oil and smoke can be absorbed completely through the limited negative pressure of the suction opening.
Description
Technical field
The present invention relates to a kind of range hood, relate in particular to a kind of air inlet of cooking-fume exhauster.
Background technology
Current, the air inlet of cooking-fume exhauster that uses in the family generally has two kinds, a kind of structure is seen Fig. 5, comprise a body 5, body 5 is provided with a suction inlet 50, and oil smoke is sucked the inlet scoop from suction inlet by 50, this inlet scoop in use, find that there are the following problems: because the suction function of inlet scoop is limited and inlet scoop and fume pollution spacing from bigger, oil smoke rapid diffusion generation under the molecular thermalmotion effect is excessive, makes the oil suction cigarette not thorough; Another kind of structure is for being provided with the inlet scoop above the fume pollution source, the inlet scoop connects air intake device, a because operation such as need to carry out cooking between inlet scoop and the fume pollution source, cook times, so the distance between inlet scoop and the fume pollution source must be bigger, so, oil smoke rapid diffusion under the molecular thermalmotion effect produces excessive, makes the oil suction cigarette also not thorough.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of air inlet of cooking-fume exhauster is provided, this inlet scoop and fume pollution spacing make the negative pressure that the inlet scoop is limited can make the more thorough of oil smoke absorption from less.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of air inlet of cooking-fume exhauster, comprise the body that is provided with a suction inlet, suction inlet connects exhaust system by pipeline, described body extends a shade to top, oil pollution source, described shade is having an inner recess with corresponding position, fume pollution source, described suction inlet is located on the sidewall of this inner recess and part is surrounded the side top in fume pollution source, and the maximum cross-sectional shape in the shape of cross section of described inner recess and fume pollution source is suitable.
In the technique scheme, the size of described inner recess inner rim is greater than the size of neighboring, upper surface, fume pollution source.
Beneficial effect: the present invention compared with prior art has following beneficial effect:
The present invention is because a shade is extended at the suction inlet place forward, and on shade, have a recess, make suction inlet partly surround fume pollution source top, make inlet scoop and fume pollution spacing from less, so, the negative pressure that the inlet scoop is limited can make the more thorough of oil smoke absorption, and it is excessive to reduce oil smoke.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
By the vertical view of the structural representation of air inlet of cooking-fume exhauster shown in Figure 1 and air inlet of cooking-fume exhauster shown in Figure 2 as can be known, air inlet of cooking-fume exhauster comprises the body 1 that is provided with a suction inlet 14, suction inlet 14 connects exhaust system 3 by pipeline 15, the below of body 1, one frying pan 2 is placed on the kitchen range top, described frying pan 2 forms a fume pollution source, described body 1 extends a shade 10 that has a style of one's own with it to frying pan 2 tops, described shade 10 is having inner recess 11 in corresponding position, fume pollution source, described suction inlet 14 is located on the sidewall of this inner recess 11 and part is surrounded the side top of frying pan 2, the cross section of described inner recess 11 is a semicircle shape, for adapting to the shape of different frying pan 2, the shape of cross section of this inner recess 11 also can be selected with the external surface shape of frying pan 2 upper ends suitable, and the size of described inner recess 11 inner rims 12 is greater than the size of neighboring, frying pan 2 upper surface 20, when cooking is weighed in the hand spoonful, be difficult for running into like this.
During work, see Fig. 3, Fig. 4, the oil smoke 100 that frying pan produces, exhaust system produces negative pressure, makes oil smoke 100 enter the inlet scoop, enter exhaust system 3 by pipeline 15, discharge by exhaust system 3 afterwards, because the inlet scoop envelope on the pot limit, makes inlet scoop and fume pollution spacing from very near, the negative pressure that just produced by exhaust system 3 before oil smoke 100 does not spread sucks in the inlet scoop, and it is excessive to significantly reduce oil smoke 100.
