A kind of oil-fume exhauster

Technical field

The utility model is related to a kind of oil-fume exhauster.

Background technology

Cooking or during barbecue as you know, the harmful substance in the oil smoke of generation can cause great harm to human body, Often in contact with that skin of face hair oil, pore can be caused thick, dark and gloomy etc., hair has peculiar smell, can also obscure ophthalmic len, excessive suction Can make one body obesity occur, it is slow in reacting, suffer from " oil smoke syndrome ", or even induce the diseases such as lung cancer, rhinocarcinoma.

Existing to go oil smoke method to be exactly gravity-flow ventilation or suction oil smoke, existing range hood mainly has two kinds of structures, one It is top suction type structure to plant, and the height that exactly range hood is horizontally arranged at from 80 centimetres above the kitchen range top aspirates oil smoke, Er Qieyi Surely the height of cooking eye is above, because only that such height will not just block the sight of cooking people, volume is not bumped to Head.The exhausting effect of top suction type fume-exhausting is influenceed by exhausting amount, blast, power of motor, the bigger exhausting effect of value of these three parameters Fruit is better, but haves the shortcomings that 5 aspects：1. because from there is 70-80 centimetres with a distance from cooking pan, the oil smoke that cooking is produced is easy Bleed around, the distance of cooking people nose and cooking pan is shorter than the distance of range hood and cooking pan, people or often suction Enter that a large amount of oil smoke are unhealthful, about 30-40% oil smoke diffusion kitchen, this is insurmountable problem.2. power of motor is big, Usually more than 200 watts, power consumption is increased., cannot after using half a year 3. existing top-sucking kitchen ventilator noise is big Cleaning, its noise is to increase, and allows people to be impatient at.4. top-sucking kitchen ventilator is complicated, including housing, turbo-dynamo, Air-guiding aisle, speed regulator etc., maintenance cleaning is inconvenient.5. manufacturing cost is high, sale price is typically 2000-4000 members, and is pacified Limited during dress by kitchen environment, if apartment does not have common flue, just be inconvenient to install.

Another existing side-suction type structure range hood, is vertically mounted on kitchen range top antetheca, due to that can not influence dish pot shifting It is dynamic, and prevent flame calcination range hood, general 20-30 centimetres of edge of side extraction cooking fume extractor horizontal range dish pot.From dish pot In the oil smoke that rises up slowly only have one side to be absorbed, other three faces still readily diffuse into kitchen, are inhaled into nasal cavity, about 25-35% oil smoke is diffused into kitchen, and this is due to remote from a distance from pot, and top suction is inadequate, it is impossible to solve high-efficient lampblack absorbing The problem of.

Application number CN's 201520286675.7《The pot-cover-type range hood that angle can be adjusted arbitrarily》Patent, fume-exhausting Machine is that, by interior gas skirt, outer gas skirt, centrifugal blower composition, interior gas skirt is fixedly connected under outer gas skirt by connecting rod Side, the diameter of outer gas skirt is bigger than the diameter of interior gas skirt, and cavity body, outer gas skirt are formed between outer gas skirt and interior gas skirt The edge of edge and interior gas skirt formed vent, the exhaust duct of centrifugal fan be provided with annular aspirating unit, outer gas skirt It is connected with the vent of outer gas skirt；It forms cavity body in the gas skirt of pot-cover-type, passes through connected telescoping tube Under the suction of centrifugal fan, the cigarette, gas, oil of cooking food generation are arranged by the annular aspirating unit around gas skirt Go out outdoor.This technology personnel think the patent formula using double-deck gas skirt, and complicated weight is big, after a period of time, Greasy dirt in the middle of double-deck gas skirt is difficult cleaning, causes suction to decline.Due to being closing when pot cover is put on dish pot, it is impossible to While fume-exhausting, with slice cooking and food is taken, using extremely inconvenient；When pot cover is lifted, equivalent to existing side Sucking kitchen ventilator, mainly inhales the oil smoke of a side, for pot top or the oil smoke of other side ascensions, it is impossible to effectively take out Row, can allow most of oil smoke to be diffused into kitchen.

Application number CN's 201520236411《A kind of sucked type movable cooker hood》Patent, sucked type is removable to be taken out Lampblack absorber is made up of sucker upper cover, horizontal smoke pipe, outer smoke pipe, electric rotating machine, lifting motor, internal flue and blower fan, and sucker upper cover is led to Cross horizontal smoke pipe to be connected on outer smoke pipe, outer smoke pipe is connected through kitchen range top face with internal flue, and the internal flue other end is connected with blower fan, wind The oil smoke extracted out when machine is operated in sucker upper cover intake line is discharged by air outlet, provided with control at internal flue below kitchen range top face Horizontal smoke pipe and the flexible lifting motor of outer smoke pipe, are additionally provided with the electric rotating machine for controlling outer smoke pipe to rotate.This technology personnel think this Patent formula uses electric rotating machine and lifting motor, causes complicated cost high, and be easily damaged difficult maintenance part more.Inhale Disk upper cover is also to use traditional circular enclosure, equivalent to existing top suction type smoke exhaust ventilator, when being less than 30 centimetres apart from pot, Block vision and slice free movement, it has not been convenient to cooking.

Existing extractor hood structure part is above more than ten, complicated, and the product component of each manufacturer Structure is different, it is impossible to which compatibility is used, and does not accomplish popular cheapization and generalization.The utility model people observes existing fume-exhausting The distance for the height and distance kitchen range top that machine is installed has the minimum of an industry universal.For top suction type structure range hood, Height only higher than 70 centimetres of minimum just can guarantee that the sight for not blocking cooking people, does not bump to forehead, does not interfere with pot The motion of shovel and take food.For side-suction type structure range hood, kitchen range top antetheca is vertically mounted on, due to dish pot can not be influenceed It is mobile, and flame calcination is prevented, general side-suction type fume-exhausting is not less than 20 centimetres apart from dish pot edge.The method of these fume-exhaustings All it is that the common knowledge of those skilled in the art and intrinsic thinking recognize with extractor hood structure, and fume-exhausting motor and collection cigarette Cover is all integrative design, does not consider that splitization is designed, small product size is huge, in order to improve remote smoke absorption effect, collects cigarette Be covered with it is one meter long, it is half meter wide, influence it is attractive in appearance.And can only using power the big motor of big, exhausting amount, this also result in machine into This height, the big power consumption of noise is big, does not meet the use requirement of user.
