Abstract
The utility model discloses a back-feed type cooking fume exhauster which is mainly composed of a machine body and a fume collecting hood connected with the machine body, wherein, the machine body is provided with an air inlet and an air outlet; a turbofan is arranged in the machine body; an inverted conical fume collector is arranged in the fume collecting hood and below the turbofan and the air inlet; a plurality of air inlet holes are arranged between the air inlet and the inverted conical fume collector. The utility model is suitable for kitchens, dining rooms or other places which needs cooking fume exhausting.
Description
The utility model relates to a kind of feed-back type smoke exhaust ventilator.
The present smoke exhaust ventilator that uses in the kitchen, mostly adopting the whirlpool blade fan to connect smoke collecting device forms, the convection current of flue dust straight line is discharged from the blade fan of whirlpool, the shortcoming of this type of smoke exhaust ventilator is because the convection current of flue gas straight line is discharged, it is big the gas outlet negative pressure to have occurred, and flow velocity is fast, and smoke collecting device around make flue gas flow rate slow because of negative pressure is little, no matter be unit or two-shipper smoke exhaust ventilator, the flue gas around the smoke collecting device is difficult to be discharged to outdoor.
The purpose of this utility model is to provide a kind of modern design at the shortcoming of above-mentioned lampblack absorber existence, and is rational in infrastructure, the happy feed-back type smoke exhaust ventilator of discharging fume.
The utility model is the feed-back type smoke exhaust ventilator, for achieving the above object, adopted following technical scheme: mainly form by lampblack absorber body and coupled poly-petticoat pipe, be provided with the whirlpool blade fan in the body, body is provided with gas outlet and air inlet, below whirlpool blade fan and air inlet, in exhaust fume collecting hood, also be provided with the inverted cone smoke-collecting apparatus, also be provided with some air admission holes between the air inlet of inverted cone smoke-collecting apparatus and body.
The utility model compared with prior art has following obvious advantage.Because inverted cone plays shunting action, the shortcoming of directly having contained former straight line convection current, accelerated the flow velocity of flue gas, simultaneously, also increased poly-petticoat pipe negative pressure all around, thus the scope of stream cigarette collected around having enlarged poly-petticoat pipe, and form a kind of negative pressure circle of entad potential energy, promoted the anti-overflow body of the bead feedback polymerization all around of poly-pressure cover, fast the effect of discharging.The utility model is applicable to that kitchen and dining room etc. need the place of range hood.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model overall structure cut-away view.
Fig. 2 is another embodiment overall structure cut-away view.
Fig. 3 is another example structure schematic diagram.
As shown in Figure 1, the utility model is made up of body 2 and coupled poly-petticoat pipe 7, body 2 is provided with air inlet 4 and gas outlet 1, be provided with turbofan 3 in the body 2, below turbofan 3 and air inlet 4, in poly-petticoat pipe 7, be provided with inverted cone smoke-collecting apparatus 6, also be provided with some air admission holes 5 between the air inlet 4 on inverted cone smoke-collecting apparatus 6 and the body 2.
As shown in Figure 2, also be provided with an air leaving cover 9, also be provided with extra-air inlet 8 at exhaust fume collecting hood 7 four jiaos in the outside of body 2.
As shown in Figure 3 be the feed-back type purification range hood, it has increased sealing pond 11 and circulating water pool 15 on the basis of feed-back type smoke exhaust ventilator, circulating water pool 15 is provided with water circulating pump 14.Gas outlet 1 connecting duct 10 of smoke exhaust ventilator, conduit 10 is inserted in the liquid in sealing pond 11, make gas cleaning, flue gas through purifying is flow in the vaccum suction pipe 12, air in the vaccum suction pipe 12 is under the impact of water circulating pump 14 spout vectors, produce negative pressure, suction air makes Purge gas discharge from Purge gas outlet 13.
Inverted cone smoke-collecting apparatus 6 of the present utility model also can adopt semi-circular design, and effect is identical.
The utility model is applicable to that kitchen and dining room etc. need the place of range hood.
