Abstract
The utility model relates to a ventilator with low noise and huge oil absorption, which is a novel ventilator used for pumping the oil smoke generated in the kitchen. The technical proposal of the utility model is characterized in that an oil collection tray 3 tightly connected under an oil collection cover 2 is separated and moved downwards, and the oil collection cover 2 and the oil collection tray 3 are connected with each other through a connecting part 4, which enables a passage A with big area to be generated between the edge sides of the oil collection cover 2 and the oil collection tray 3. The traditional method that oil smoke enters into a plurality of small holes of the oil collection tray 3 from just below the oil collection tray 3 is replaced with the method the oil smoke enters into the passage with big area from the lateral side of the oil collection tray 3, which reduces the intake wind resistance of the oil smoke, lowers noise, improves the air pressure difference between an air inlet and an air outlet, and evidently improves the pumping force and discharging force of the ventilator; therefore, without increasing in the power of the ventilator, the utility model can achieve the purpose of low noise, strong wind and oil saving effect.
Description
One, technical field
The utility model relates to a kind of range hood, specifically a kind of low noise loudness of a sound range hood.
Two, background technology
At present, on the technical field of research and development range hood, exist so a pair of contradiction all the time: the suction that increase range hood just certainly will increase 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 owing to its noise of increase of range hood power has also correspondingly increased, and noise is a kind of modern pollution as everyone knows.
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 original range hood closely are connected as one changes to exhaust fume collecting hood 2 and draw-off tray 3 split-type structurals, enlarge its air intake passage, reduce its 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 utility model low noise loudness of a sound range hood is: it comprises cabinet (1), exhaust fume collecting hood (2), draw-off tray (3), lubricating cup (5), illuminating lamp (6) of range hood etc.; Cabinet (1) is in the top of exhaust fume collecting hood (2), 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), illuminating lamp (6) is about the place ahead of exhaust fume collecting hood (2), it is characterized in that it also be included between exhaust fume collecting hood (2) and the draw-off tray (3) a circular passage CA is arranged), between exhaust fume collecting hood (2) and the draw-off tray (3) by connector (4) affixed.Since the utility model low noise loudness of a sound range hood seat exhaust fume collecting hood (2) below and the draw-off tray (3) that closely is attached thereto to moving down, make a circular passage (A) has been 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) aperture 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, to strengthen the hydromechanical basic principle of suction force, thereby reach under the prerequisite that does not improve range hood power, significantly strengthened suction discharging strength oil smoke.
Four, description of drawings
Fig. 1 is the shape assumption diagram of former range hood.
Fig. 2 is the shape assumption diagram of the utility model low noise loudness of a sound range hood.
Among the figure: cabinet (1) is in the top of exhaust fume collecting hood (2), draw-off tray (3) has a circular passage (A) between the two in the below of exhaust fume collecting hood (2), and is fixed together with connector (4), lubricating cup (5) is in the below of 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 the specific embodiment of the utility model low noise loudness of a sound range hood is described further:
At first, on the basis of former range hood structure, the draw-off tray 3 that closely is attached thereto with exhaust fume collecting hood 2 belows is thrown off to moving down, make and produce large tracts of land passage A between both avris, and be fixed together with connector 4, therefore, when the low noise loudness of a sound range hood after improving is worked, oil smoke is by pot, when jar or web side formation round upwards volatilize, in the equal admission passage A of the overwhelming majority, therefore than traditional oil smoke major part by under to enter numerous aperture resistances of draw-off tray 3 much smaller, simultaneously owing to increased oil smoke air inlet cross section, thereby greatly reduce the noise of range hood work and improved the pressure reduction of range hood inlet and outlet, significantly improved the suction discharging strength of range hood oil smoke.
Claims (1)
1. low noise loudness of a sound range hood, it comprises the cabinet (1) of range hood, exhaust fume collecting hood (2), draw-off tray (3), lubricating cup (5), illuminating lamp (6); Cabinet (1) is in the top of exhaust fume collecting hood (2), 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), illuminating lamp (6) is about the place ahead of exhaust fume collecting hood (2), 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 between exhaust fume collecting hood (2) and the draw-off tray (3) by connector (4).
