Description
Technical field
The present invention relates to a kind of air exhausting device that is used for the kitchen kitchen range, particularly relate to a kind of negative jet proximity type side draught downward air exhaust fume exhaust device.
Background technology
Early stage family kitchen smoke evacuation work is all finished by ventilating fan.Though ventilating fan can exclude the most of oil smoke in the kitchen, the oil smoke that produces in its unable solution culinary art is to whole kitchen pollution.The oil smoke that produces in the culinary art contains a lot of harmful materials, if the people works in being full of the room of oil smoke for a long time, can cause the generation of a lot of diseases.
For Chinese, diet structure is different with the westerner, thus in the kitchen from the kind of kitchen tools, pattern to layout, all be very different with western countries.China is the country of exquisite cuisines, in food processing, Fried, fried, cooked, fried occupy very big ratio, so the oil smoke in the Chinese style kitchen is very big, make the kitchen environment greasy and bad cleaning that becomes easily, so smoke exhaust ventilator has just become to change one " powerful mean " of kitchen environment.It has changed the overall situation in kitchen, reduces oil smoke kitchen environment and health are damaged.Smoke exhaust ventilator is kitchen " lung ".
Smoke exhaust ventilator commonly used at present is divided into three kinds: the one, and Chinese style cigarette machine, the 2nd, European cigarette machine, the 3rd, side-suction type.
Chinese style cigarette machine mainly is divided into old-fashioned shallow deep suction type smoke exhaust ventilator, and especially shallow suction formula is the main object of eliminating, and is exactly common exhaust fan, be directly oil smoke is discharged to outdoor.The problem of deep suction type cigarette machine maximum is to take up room greatly, and noise is big, meets and discusses easily, oil dripping, and oil smoke is taken out unclean, and service life is short, cleans inconvenient, big for environment pollution.
European cigarette machine utilizes multilayer oil net filtration (5-7 layer), increases power of motor to reach optimum efficiency, and general power is all more than 300 watts.Though outward appearance is beautiful, cost an arm and a leg, take electricity, oil net cleans inconvenient, meets and discusses easily, oil dripping.
The side-suction type cooking fume remover utilizes the design of aerodynamics and hydrodynamics, utilizes the oil smoke separating plate on surface oil smoke to be separated the principle of discharging cleaned air more earlier.
The tradition smoke exhaust ventilator all is the furred ceiling design, setting height(from bottom) is generally about 700mm, and the power of fan of its mainstream model is mostly between 200～250W, so it effectively aspirates radius roughly about 400mm, thereby the pot face is fully outside its blower fan aspiration ranges, and oil smoke will be stretched everywhere from pot face one generation nature like this.Want to drain clean, on the principle of air power, it has only highly lowering, and allows the effective radius of its suction that the pot face is covered, and also can realize 99% suction effect naturally, but this obviously again can't cooking.For this reason, select suitable smoke exhaust ventilator device, have a significant impact for people's life.
