Abstract
The utility model relates to a large wind blowing low noise oil fume exhauster. The essential technical points lie in that the fume collecting hood 2 and oil collecting tray 3 of the original oil fume exhauster are disengaged and moved down. A certain space canal A is left between the fume collecting hood 2 and the oil collecting tray 3. The fume collecting hood 2 and oil collecting tray 3 are fixedly connected through connecting pieces. The traditional method that oil fume enters into a plurality of small holes of the oil collecting tray 3 from below the oil fume exhauster is changed, the oil fume enters into a large-area canal through brinks so as to reduce the air intake resistance of the oil fume, enlarge the differential pressure of an air intake and an air outtake, and strengthen the suction and exhaust power of the oil fume exhauster to reach purposes of large suction air volume, small noise and low power consumption.
Description
One, technical field
The utility model relates to a kind of powerful range hood of discharging oil smoke, specifically a kind of big air quantity low noise range hood of aspirating.
Two, background technology
At present, on the technical field of research and development range hood, exist a pair of like this contradiction all the time: the suction that increase range hood just certainly will strengthen the power of range hood.This just means: manufacturer has to improve the manufacturing cost of range hood; Users had to pay the more electricity charge in every month; And because the also corresponding increase of its noise of increase of range hood power, and noise is a kind of modern pollution.
Three, summary of the invention
The technical scheme of the utility model technical issues that need to address and proposition is: the structure that the exhaust fume collecting hood 2 and the draw-off tray 3 of former range hood closely are connected as one is modified to exhaust fume collecting hood 2 and draw-off tray 3 split-type structurals, enlarge air intake passage, reduce the air intake resistance, thereby under the prerequisite that does not improve range hood power, strengthen the suction discharging strength of range hood to greatest extent to oil smoke.
The technical scheme of the big air quantity low noise of the utility model range hood is: it comprises cabinet 1, exhaust fume collecting hood 2, draw-off tray 3, lubricating cup 5, illuminating lamp 6 etc.; Cabinet 1 is above exhaust fume collecting hood 2, draw-off tray 3 is below exhaust fume collecting hood 2, lubricating cup 5 is below draw-off tray 3, illuminating lamp 6 is about the place ahead of exhaust fume collecting hood 2, it is characterized in that it also is included in a circular passage A is arranged between exhaust fume collecting hood 2 and the draw-off tray 3, affixed by connector 4 between exhaust fume collecting hood 2 and draw-off tray 3.Because the utility model is being positioned at exhaust fume collecting hood 2 belows and the draw-off tray 3 that closely is attached thereto to moving down, make a circular passage A is arranged between the two, change traditional oil smoke major part by under enter draw-off tray 3 numerous apertures be that the oil smoke major part enters large tracts of land passage A by avris, met the actual condition that oil smoke is greatly partly produced by avris, and significantly reduced oil smoke and enter behind draw-off tray 3 apertures and increase resistance that produces and the noise that thereupon produces because of flow velocity, also met the oil smoke air inlet cross section that common manufacturer is ignored (being the gross area of all apertures on the draw-off tray 3) and must could strengthen the pressure reduction that passes in and out wind greater than the exhaust duct cross section, strengthen the hydromechanical basic principle of suction force, thereby under the prerequisite that does not improve range hood power, significantly strengthened suction discharging strength to oil smoke.
Four, description of drawings
Fig. 1 is former range hood shape assumption diagram:
The big air quantity low noise of Fig. 2 the utility model range hood shape assumption diagram;
Among the figure: cabinet 1 is above exhaust fume collecting hood 2, and draw-off tray 3 has a circular passage A between the two below exhaust fume collecting hood 2, and connector 4 is between exhaust fume collecting hood 2 and draw-off tray 3, and lubricating cup 5 is below draw-off tray 3, and illuminating lamp 6 is about the place ahead of exhaust fume collecting hood 2.
Five, the specific embodiment
Below in conjunction with Fig. 2 implementation process of the present utility model is described further:
On the basis of former range hood structure, throwing off to bottom offset with the draw-off tray 3 that exhaust fume collecting hood 2 closely links to each other, make and produce passage A between both avris, and be fixed together with connector 4, therefore, when the big air quantity low noise range hood after improving is worked, oil smoke is by pot, the overwhelming majority was all in the admission passage A when jar avris formed round and upwards volatilizees, therefore than traditional oil smoke major part by under to enter numerous aperture resistances of draw-off tray 3 much smaller, thereby significantly reduced noise and strengthened the pressure reduction of the inlet and outlet of range hood, the exhausted suction discharging strength of range hood that improved greatly oil smoke.
Claims (1)
1, a kind of big air quantity low noise range hood, it comprises cabinet (1), exhaust fume collecting hood (2), draw-off tray (3), lubricating cup (5), illuminating lamp (6) etc.; Cabinet (1) is in exhaust fume collecting hood (2) top, draw-off tray (3) is in the below of exhaust fume collecting hood (2), lubricating cup 5 is in the below of draw-off tray (3), it is characterized in that it also is included between exhaust fume collecting hood (2) and the draw-off tray (3) circular passage (A) is arranged, affixed by connector (4) between exhaust fume collecting hood (2) and draw-off tray (3).
