Description

Near-suction type smoke purifier

Technical field

The utility model relates to the equipment of handling catering trade or oil smoke that family kitchen discharges, refers to a kind of near-suction type smoke purifier that mainly is installed in cantilever platform window place, kitchen particularly.

Background technology

Along with the enhancing day by day of numerous common people's environmental consciousness, also more and more higher to self and environment requirements, the control of air environmental pollution has become the task of top priority.Relevant survey data shows: in the air ambient pollutant in big or middle city, the pollution that catering trade and family's oil smoke cause has surpassed vehicle exhaust, about 40～50% in the atmosphere pollution, kitchen fume pollution, the fume pollution problem has become the emphasis of current environmental protection regulation.

At present, it is of a great variety to be used for the device that kitchen fume handles, and wherein has quite a few to be mounted in straight-line ventilating fan or smoke exhaust ventilator on the cantilever platform window of kitchen.This type of device can directly be pumped to indoor oil smoke outdoor, its advantage is to have pump drainage effect preferably when using in early days, but in use subsequently, exist very big problem: one, straight-line ventilating fan and smoke exhaust ventilator are not all held back or the effect of purifying oil fume, oil smoke directly row has not only polluted air after outdoor, and polluted outside vertical surface of building, had a strong impact on urban environmental hygiene and people's health.They are two years old, a large amount of easily long-pending oil on straight-line ventilating fan and the smoke exhaust ventilator, need frequent disassembly, cleaning, cleaning is very heavy, all necessary cleaning in time after each culinary art, otherwise time one is long, and a large amount of greasy dirts stockpiles inner and its peripheral region at its movement, can cause that balance of fan variation, the corresponding increase of noise, suction capactity decline to a great extent, the life-span shortens dramatically.

At the defective that straight-line ventilating fan or smoke exhaust ventilator exist, the scientific research personnel has designed the top suction type smoke purifier that is installed in directly over the kitchen range top, and such type is drawn oil smoke by the ventilating fan at top, and by filter mesh layer oil smoke is retained down.The top suction type smoke purifier has slim machine by highly dividing, dark type machine and marginal half dark type machine etc.Slim machine is very shallow because of exhaust fume collecting hood, can not reach the effect of rapid pump drainage oil smoke, and oil fume pumping-clean rate is about 40% only, is eliminated basically now; Dark type machine is darker because of exhaust fume collecting hood, has certain cushioning effect, during exhausting not the oil smoke of emptying can temporarily be contained in the exhaust fume collecting hood, avoided the diffusion of part oil smoke, the effect of its pump drainage oil smoke is better than slim machine, but oil fume pumping-clean rate also only has 50～60%.Trace it to its cause, the general setting height(from bottom) of top suction type smoke purifier about 700mm, and wherein the operating radius of air exhauster roughly between 400～500mm.Oil smoke produces at kitchen range top pot face, will run wild in case produce, and oil smoke had just scattered before entering clearing machine on four sides like this, caused oil fume pumping-clean rate very low.If setting height(from bottom) is reduced to from kitchen range top pot face 400～500mm, because existing top suction type smoke purifier generally needs a big exhaust fume collecting hood and prevents the oil smoke diffusion, its width is about about 500mm, and its volume is bigger, this will cause can't cooking, and has problem such as meet and discuss, polish.

In order to solve the problem of top suction type smoke purifier in setting height(from bottom), occurred the side-suction type smoke purifier in recent years, it is installed in kitchen range top side, and setting height(from bottom) is nearer from the kitchen range top, from the side the oil smoke that produces is siphoned away during culinary art, and adopt filter to separate and purifying oil fume.The side-suction type smoke purifier improves to suction, the detergent power of oil smoke, but still has following defective:

The first, noise is excessive, and service life is of short duration.The noise of side-suction type smoke purifier when work mostly surpassed 60 decibels, and this is relevant with its working method.Because being actually, the motor of side-suction type smoke purifier and fan be contained in the machine cover top portion; suitable distance is arranged between its air inlet and motor and the flabellum; and air inlet is very near from the kitchen range top; casing inner wall usually can be by waste oil pollution; cause a large amount of inhomogeneous long-pending oil of draught fan impeller; blower fan rotates and loses dynamic balancing, so its suction effect naturally just worse and worse, its mechanicalness noise is also increasing.If things go on like this, equipment is easy to damage.

The second, loss heat energy and cooking space, and have potential safety hazard.The working face of side-suction type smoke purifier is very near apart from cooking area, because it is an air intake from the side, could arrive air inlet so oil smoke need turn an angle again, and this just needs the effect that bigger wind-force just can reach the absorption oil smoke.If but wind-force is too big, be easy to cause the heat energy of cooking stove to run off again.And because its near excessively suction, cause partial oxygen supply thin, make coal gas or combustion of natural gas insufficient, after therefore often having the user to reflect to have used the side-suction type smoke purifier, coal gas or natural gas consumption heighten, and this explanation side draught mode is double-edged sword on suction capactity and combustion gas efficiency.Equally, because the side-suction type smoke purifier is very near apart from the cooking stove duration and degree of heating, the part that extends out from the wall facade is bigger, cause cooking space to diminish, the cook utensil of large volume or high altitude such as food steamer, steamer etc. almost can directly be met its air inlet, and use has inconvenience more, and security is relatively poor.

In addition, no matter be top suction type smoke purifier or side-suction type smoke purifier, they all can only hold back the sub-fraction oil smoke by static screen pack, clean-up effect to oil smoke is very limited, most of oil smoke still directly is pumped to outdoor, does not fundamentally solve the difficult problem of fume pollution air and outside vertical surface of building.For this reason, nation-building portion forces to have promoted the central exhaust pipeline.Though like this from the cleaning that intuitively guaranteed external surface of buildings and attractive in appearance, but because shortage is to effective purified treatment of oil smoke, the central exhaust pipeline can not tackle the problem at its root, high row is still serious to the pollution that air ambient causes for oil smoke, and has that smoke evacuation is smooth, flue gas pours in down a chimney, taint of odour, grows problem such as the mosquito plague of rats.
