Abstract
The utility model provides a fume extractor with a silencer, which is composed of a machine shell, a motor, an impeller, an airfoil vane, an air inlet rectifying cover, an air outlet rectifying cover, a guide vane and a motor seat cover. The utility model is characterized in that the front end of the inlet rectifying cover is provided with a porous silencing cover made by a structure with multiple layers, and meanwhile, the front end of the multilayer silencing cover is yet provided with an oil gathering plate which has a shape of a leaf and a certain angle of inclination. The fume extractor with the device not only can completely clean fume, but also has a strong denoising function. The utility model can be widely used in families, in dining rooms of hotels, etc.
Description
The utility model relates to kitchen utensils, particularly a kind of smoke exhaust ventilator with silencing apparatus.
Smoke exhaust ventilator is the indispensable oil smoke discharge apparatus of general family kitchen.Smoke exhaust ventilator produces machinery and pneumatic noise inevitably in operation process, the tobacco tar drippage is arranged inevitably.Noise increases along with the increase of air mass flow blast, and this noise major part directly diffuses out from air intake vent.Therefore, the important reform that silencing apparatus is this technical field is set near air intake vent.
The purpose of this utility model provides a kind of simple in structure, novel in design, the smoke exhaust ventilator with stronger oil-collecting and noise elimination effect.
The purpose of this utility model is achieved by the following scheme: be made of casing, motor, impeller, airfoil fan, inlet air radome fairing, air-out radome fairing, guide vane, motor cover for seat, the front end that wherein is positioned at the inlet air radome fairing is provided with the cellular sound proof housing that sandwich construction is formed, and the front end that is positioned at this multilayer sound proof housing simultaneously also is provided with the oil collection plate that leaf shape has certain inclination angle.
Above-mentioned sound proof housing can be that cavernous metal or nonmetallic materials are made, and the ground floor of its sound proof housing is fixed indispensability, and second and third layer can be selected the setting of single or multiple lift structure according to the characteristic of noise.
The utility model compared with the prior art, have simple in structure, novelty reasonable in design.Its effect comprises three aspects, first reflection, absorption noise; It two is thoroughly to collect the tobacco tar that drips down from impeller, blower fan; Steam that rises when being the cooking again and oil smoke are when touching oil collection plate, and water column that cooling forms and oil droplet meeting nature flow to terminal aperture along the oil collection plate that tilts, and then flow in the oil-collecting bottle, thereby reach thorough removing oil smoke and the purpose that reduces noise.
Below in conjunction with accompanying drawing the utility model is illustrated.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1: this smoke exhaust ventilator is by casing 1, motor 2, impeller 3, airfoil fan 4, inlet air radome fairing 5, air-out radome fairing 6, guide vane 7, motor cover for seat 8, cellular sound proof housing 9,10,11, and leaf shape has the oil collection plate 12 at certain inclination angle and oil storage bottle 13 to constitute jointly.It is to install at the front end of air intake vent to have strong decrease of noise functions that the primary structure of this smoke exhaust ventilator improves, by one or more layers cellular sound proof housing that constitutes 9,10,11, the front end that is positioned at this multilayer sound proof housing simultaneously also is equipped with the oil collection plate that leaf shape has certain angle of inclination, thereby has constituted a novel cooking fume exhauster with stronger decrease of noise functions.Above-mentioned sound proof housing can adopt metal material processing to make, and also can adopt nonmetal or plastic material is processed into.
