One. household smoke exhaust ventilator present situation
Kitchen fumes pollutes has certain influence to health, makes human respiratory tract's mucous membrane impaired, reduces immune function of human body, cause suffering from nasopharyngeal carcinoma, lung cancer, laryngocarcinoma possibility greatly increase.Kitchen fumes also stimulates the eyes of people, thus brings out angiocardiopathy.
Because household gas range three face is all unlimited, current panoramic household smoke exhaust ventilator does not all have absolutely oil smoke to be rejected to open air.At present in the patent of 1,200 kinds of household smoke exhaust ventilators, no matter be overhead type deep hood type, shallow cover type, or lateral cooker hood, overflow from limit always the smoke exhaust ventilator of all structures has oil smoke.Especially the plate smoke exhaust ventilator of overhead, the situation that oil smoke overflows is more serious.Producer is no wonder had commercially to release the smoke exhaust ventilator of speciality extra wide again.It grows 30 centimetres than general smoke exhaust ventilator in the longitudinal direction, in the direction of the width then wide go out 15 centimetres.And the top of lateral cooker hood and side are due to inadequate without blocking or block width, fumes escaping is had to go out equally.
At present in what is called " totally-enclosed smoke exhaust ventilator " that is commercially available and that occur in the patents such as application for a patent for invention number 03114827.1, be actually and adopt exhaust fan and fiberglass as ceiling, stainless steel angle steel as support, with glass or certain fabric or transparent material at gas-cooker three or circumferential closed cabinet (bucket) formula smoke exhaust ventilator.Its shortcoming is apparent: sight line smooth, operation inconvenience during cooking, oil smoke can be run out when opening the door, and cupboard inside needs cleaning frequently, time-consuming, and the Modern Decorative in this indigenous method and kitchen or parlor is extremely inharmonious.
In recent ten years, some patents propose and adopt air curtain local or all close oil smoke, this imagination very well, but technically but there is deviation what how to produce air curtain, and more or less all there are some problems result of use, the more important thing is that these patents are not also really implemented.Dissect for some more typical patents below:
The ZL patent No. 02245890.5 adopts the pipe of holing in gas-cooker surrounding to produce air curtain, and certainly have the hermetic effect of oil smoke, natural exhaust fume collecting hood and motor also can in order to avoid unpick and wash.Its shortcoming is exactly produce the motor of air curtain and long long airduct all in outdoor mounted, and wall also will make a call to two holes, and this design can only be used in the resident family staying in one-storey house, and the building user that the family overwhelming majority is occupied in the whole nation all cannot implement.Whole commercialization of design degree is too poor, and therefore it cannot be promoted.Also have several patent to propose to do underfloor vent pipe or ventilating water pipe, do not have which user can go oneself to go to implement.
The ZL patent No. 98234620.6 produces downward gas curtain along three limits under adopting smoke exhaust ventilator, is three faces to the sealing of oil smoke.But the technology producing gas curtain is but a large problem: this patent does not have significant improvement to the technology of existing smoke exhaust ventilator, therefore its gas curtain is laid by blower fan with the oil smoke be drawn into from the kitchen range top to be formed again, can this be called " smoke exhaust ventilator "? oil smoke is pumped up and send again, does not this make an unnecessary move? the smoke exhaust ventilator of this patent does not a bit purify oil smoke, does not meet the requirement of Environmental Protection Agency to kitchen discharge fume purifying degree.
ZL patent No. 200610081225.X solves the ZL patent No. 98234620.6 open question, and adopt two cover motor and fans, a sleeve pipe smoke pumping, a sleeve pipe produces downward air curtain.But the direction that moves downward of air curtain follows the oil smoke direction of motion upwards just in time contrary, this is unfavorable for that oil smoke moves upward, it can drive the periphery oil smoke of tens of air curtain air quantity times to move downward, and the turbulent flow of this cooking fume makes lampblack-pumped efficiency greatly reduce.Air curtain or the large Eight characters of this patent open downwards, also affect the effect of isolating oil soot.The patent of many invention air curtains carrys out isolating oil soot along producing downward air curtain under mostly adopting the exhaust fume collecting hood of overhead smoke exhaust ventilator, does inventor have the shortcoming not expecting this scheme? another one shortcoming, this invention does not a bit avoid the common defect of common smoke exhaust ventilator: still need to unpick and wash fan electromotor and blade.
This invention of utility model patent Authorization Notice No. CN201748514 U adopts motor two sleeve impeller to realize launching air curtain downwards, upwards extract the object of oil smoke, shortcoming is that the direction that moves downward of air curtain follows the oil smoke direction of motion upwards just in time contrary, cause the turbulent flow of upwards cooking fume, the turbulent flow of this cooking fume makes lampblack-pumped efficiency greatly reduce.Air curtain or the large Eight characters of this patent open downwards, also affect the effect of isolating oil soot.Also need to unpick and wash fan electromotor and impeller.
Application for a patent for invention publication No. CN101858613 A attracts oil smoke to move to smoke exhaust pipe along producing air-flow upwards under tubaeform exhaust fume collecting hood, again can isolating oil soot to the pollution of exhaust fume collecting hood inner surface, avoid unpicking and washing of motor and fan.Its shortcoming to intercept the oil smoke of blowing out outside exhaust fume collecting hood.
The effect of application for a patent for invention publication No. CN101936563 A and this invention isolating oil soot of utility model patent Authorization Notice No. CN201819289 U is pretty good.Shortcoming is that the blade of pipeline fan still has oil smoke to stain.Below the kitchen range top, air blast is housed, concerning troubles of a finishing many user.
Four patents such as application for a patent for invention publication No. CN 102042630 A, utility model patent Authorization Notice No. CN 201983324 U, application for a patent for invention publication No. CN 102052701 A and utility model patent Authorization Notice No. CN 202002180 U, using same schematic diagram of structure, is therefore a type technically: namely adopt Venturi tube and Roots blower.Application for a patent for invention publication No. CN 102042630 A, utility model patent Authorization Notice No. CN 201983324 U two pieces patent of invention have and clearly represents.If really can implement, result of use should be good.The main defect of common smoke exhaust ventilator is effected a radical cure; Oil smoke obtains hermetically sealed, and fan electromotor, impeller been have not have not all been unpicked and washed.One of problem is that the air inlet hush pipe of Roots blower is all very long with hush pipe of giving vent to anger, whether the Roots blower of minimal type just not hush pipe? two of problem is that the volume of Roots blower is very large, its weight, air quantity, blast, power of motor, price are all very high, if select the Roots blower of the minimal type that can go in the volume of smoke exhaust ventilator, air quantity is inadequate (0.1-0.5m again
3/ point), and weight still has tens kilograms.Three of problem is smoke exhaust ventilators of these four patents is all the design of a bite pot, but on market at a glance stove can have, smoke exhaust ventilator did not have at a glance.Even if produced smoke exhaust ventilator at a glance by these patent workings, this at a glance smoke exhaust ventilator also no one buy.Four of problem is in exhaust fume collecting hood central authorities or adopts filter screen to filter oil smoke, and filter screen is all too limited to the clean-up effect of oil smoke.
Within 2003, solve only with the smoke-guiding machine commercially occurred for 2006 in 20 patents such as the utility model ZL patent No. 03262178.7 grade and gas-cooker three side sealing is closed, and the wall not obtaining closing still speckles with greasy.And its three inflatable mouths discontinuous, its two elbows and a central electronic control device do not have nozzle, and therefore three faces are not also closed completely, also have some oil smoke to run out unavoidably.The shortcoming that smoke-guiding machine is the most fatal is that strength is disperseed very much, and air velocity is very low, and only have 2.5-3 meter per second, blast is upwards decayed rapidly.Because air flow impulse is not strong, candle all can not be blown out, so it is not strong to lead cigarette ability, the flue gas mist of oil that its air curtain only can isolate above frying pan pot mouth 40 centimetres does not allow and leaks, up edge under 25 centimetres to lampblack absorber again, smoke-guiding machine air curtain strength rebounds immediately completely without the stop that the flue gas mist of oil of, rising is subject to overhead range hood baffle and leaks.What is called has had smoke-guiding machine the flue gas of pump drainage 99% to be impossible completely.Should say and use smoke-guiding machine to have a use than not using smoke-guiding machine, but smoke-guiding machine also only only plays an effect of crowding around cooking fume, it does not have ability to drive flue gas up to send in the smoking port of smoke exhaust ventilator at all.Also have electromechanical structure and the complex process of this smoke-guiding machine, it will produce micromachine and impeller in cross dimensions less than the space of 35 millimeters, manufacture and maintenance cost is high on the one hand, and the air quantity large blower fan the same as blast that it will be worked out as common smoke exhaust ventilator is on the other hand completely impossible.
Special needs to be pointed out is all types of smoke exhaust ventilators popular in the world at present, completely adopt negative pressure extracting oil smoke.According to pneumatic conveying principle, the half of the energy force rate malleation insufflation potential of negative inspiratory pressure less than.Its suction only has apart from effective during 20 centimetres, air port, does not far work.In addition oil smoke all also will be subject to the stop of baffle plate, grid, filter screen and blower fan, fan blade in the process extracted.Have a lot of lampblack absorber also all catchment cup to be arranged on the middle of lampblack absorber smoking port, its filter screen is exactly block oil smoke at the first critical point of smoking passage to enter smoke discharging pipe.Filter screen have one deck, two layers or multilayer, filter opening has square, rhombus, circle etc., object posts to wish by filter screen, oil smoke to be blocked, but from service condition so for many years, the non-constant of effect of this solution, even if filter screen little to 0.01 square centimeter time, still have the oil smoke of 37% can't stop, the opening of sieve of the most cigarette machine in market, all at about 0.04 square centimeter, is thus exactly almost directly discharged.Soon be easy to be stuck with paste full by oil stain because filter screen uses again, smoke exhaust ventilator suction at this moment completely without, half newspaper is all inhaled and is not lived.Cause again a large amount of uneven long-pending oil of draught fan impeller, blower fan rotates and loses dynamic balancing, so suction effect naturally just worse and worse, its mechanicalness noise is also just increasing.But pull down catchment cup and filter screen, the suction of blower fan still can hold a millboard.So the smoking rate of all lampblack absorbers namely 60% on the market.And be bonded at baffle plate, grid, filter screen and blower fan, fan blade greasy or need cleaning unavoidably.The side-suction type range hood not having oil catcher to stop then allows oil stain stay in the crack of casing internal layer, turn increases the trouble of cleaning oil stain.After all, range hood on the market newly installs rear firm used time effect well at present, has crossed some months just little spirit substantially, on the wall that the oil smoke spot of spilling starts to be bonded at gas-cooker side everywhere and other places, corridor, kitchen.
Make a general survey of on market and panoramic smoke exhaust ventilator in more than 1,000 kind of patent, the overwhelming majority is the function to cooking fume-collecting and purification, be placed in same cabinet all together, user has to smoke exhaust ventilator to be torn open greatly unload greatly when cleaning fan blade, extremely wastes time and energy.
Also have a lot of patent to propose to do multifunctional cooker hood, what multimedia, hot water, refrigeration, menu, monosodium glutamate, generating, micro-wave oven, TV etc., business is not all done well, does not is not doing those results seem very unnecessary?
Two. catering range hood present situation
Gas-cooker three face used due to catering trade is also all unlimited, and the smoke exhaust ventilator that current panoramic catering trade uses all does not have absolutely oil smoke to be rejected to open air yet.The exhaust fume collecting hood form that uses of catering trade is just several now, point common exhaust fume collecting hood, hydro-vent, luxury collection smoke box cover.Due in the space above gas-cooker, three faces are all unlimited, and therefore their common shortcomings are: elegant smoke flaring can not be gone along the oil smoke inspiration beyond scope.Elegant oil smoke beyond exhaust fume collecting hood has completely been stained with very thick oil stain the ceiling in kitchen and exhaust fume collecting hood top, smoke discharging pipe, electric fan, illuminating lamp, is difficult to cleaning.Because oil smoke easily spreads, kitchen air quality is also not very good.
The collection cigarette part of common exhaust fume collecting hood and luxury collection smoke box cover all adopts the grid of labyrinth structure, filter screen by stopping that oil smoke motion gathers mist of oil, when user does not remove the oil stain at the positive back side of screen in time, cross the narrower smoke evacuation system that easily causes in cigarette gap obstructed, as being also easy to breaking out of fire when cooking with heavy oil vigorous fire.
The key of hydro-vent result of use to form continuous print water curtain, and need to carry out periodic cleaning to circulation.In fact by poor management, current most of hydro-vent cannot form continuous water curtain, and just defines the water droplet of Generation-Atomic Fluorescence Spectrometry or little water column, the therefore non-constant of result of use.The mistake cigarette gap of hydro-vent is narrower, easily causes smoke evacuation system obstructed.The shortcoming of hydro-vent is also show very much: water consumption is large: 3m
3/ hour; Blower fan easily malfunctioning, the nozzle of long-pending oil, electrically complicated easily short circuit amasss oil pole and easily blocks; Maintenance cost is high.
The oil stain that the electrostatic oil and smoke cleaner that current catering trade uses in a large number is all wanted clearing electrode is stained with for every one or two week, because expense makes too greatly hotel owner not survey heavy burden, current user selects a Ge Yueqing producer messenger cleaning once, the clean-up effect of electrostatic oil and smoke cleaner to oil smoke has then been well imagined at ordinary times, and having revealed is exactly an ornament.
In big-and-middle-sized food and drink place, although mostly installed smoke evacuation system, but all smoke exhaust fans are arranged on outdoor or roof, the smoke discharging pipe that centre length is long couples together with exhaust fume collecting hood, the high-power blower adopted from exhaust fume collecting hood distance very away from, therefore the exhaust fume collecting hood hole suction losses of carrying out negative inspiratory pressure to the oil smoke above gas-cooker is a lot.And the cooking fume control equipment of quite a few is owing to designing unreasonable or mismanagement, purification efficiency is low, does not reach the effect of anticipation.
The most serious problem is that smoke discharging pipe back warp often gathers a large amount of oil stains, if after causing deep fat on fire when cooking with heavy oil vigorous fire, flame can be altered rapidly inlet pipe road and is easy to cause raging flames to cause fire disaster accident.Often when a fire starts and spreads, also get by with spray above the chafing dish that gas-cooker is lighted, and spray is also helpless when putting out the big fire in smoke discharging pipe.Not only spray don't work, and also can not find the fire extinguisher canvas hose that can meet an urgent need and uses, have to look at violent big fire helplessly and alter roof, burn dining hall even outdoor in kitchen.
In order to prevent smoke discharging pipe on fire, constantly remove the oil stain in pipeline.But this work is extremely time-consuming, and expensive especially.So the disaster hidden-trouble caused not in time due to the oil stain removed in pipeline also exists always.
Also has the stir-fry dish cooked in a small wok, meaning the food is prepared with special care restaurant in the outdoor barbecue on street, little gear, lane, street corner, every day, oil smoke billowed, especially pendulum barbecue spreads out, barbecue boss is also choked can't keep one's eyes open by dense smoke, and going on road is oil smoke entirely in air, is oil stain entirely on the ground, complaints are heard everywhere in surrounding resident family, every night, family was all one pungent greasy smell, and window all dare not be opened along the street, and pedestrians also moan and groan.In order to administer haze weather, Chinese Ministry of Environmental Protection and various places government sternly forbid in recent years " at the outdoor barbecue in the public place of Urban Areas, (window) barbecue of sitting on the fence ", and therefore the street corner barbecue of some large size cities almost disappeares completely.
Described in utility model patent Authorization Notice No. CN 202109560 U patent, off-premises station volume is smaller, and structure is also more novel, unfortunately just strengthens driving to open air of oil smoke and send, and show no sign of any purification.Therefore on the exterior wall below off-premises station, grunge pollution can be quite serious, affects the appearance of the city.
Very simple described in utility model patent ZL 200820068100.8 patent, exactly machine oil pot have been hung on outdoor wall just, shortcoming only depicts sketch, do not have structure chart, so when making people think that user climbs to stretched oil-collecting kettle on windowsill, security is too poor.
Described in patent of invention notification number CN 101718449 A, application for a patent for invention publication No. CN101520199 A patent, chimney structure is huger, not wind resistance, poor stability, and way is also more ancient, and the filtering material of use cannot be cleared up and change.
In utility model patent Authorization Notice No. CN 201836957 U patent, eliminate smoke evacuation system, allow circularly purifying in the return emission-free range hood of oil smoke in exhaust fume collecting hood.Its shortcoming be axial flow blower all the time under the exerting a gradual, corrupting influence on of oil smoke, on housing, blade and motor, oil stain needs often cleaning, time-consuming.Elegant smoke flaring can not be gone along the oil smoke inspiration beyond scope.
In application for a patent for invention publication number CN 101520201 A patent, the oil stain in flue can not be discharged in oil collection box completely, and flue inner wall speckles with many oil stains in the same old way, therefore equally keeps away the danger of unavoidable breaking out of fire.Elegant smoke flaring can not be gone along the oil smoke inspiration beyond scope equally in addition.
Summary of the invention
the operation principle of underlying ring-like air knife:
1. air blast throws air knife cavity into air, air-flow by after narrow, carefully thin nozzle along air knife length direction formed a high pressure, at a high speed, fine and close, continuous, the balanced thin cutter of gapless air-flow, thus effectively stop that oil smoke is to gas-cooker external diffusion, plays the effect of accessible isolation, shielding oil smoke.
2., again due to the principle of air amplification, the oil smoke that the thin cutter of air-flow drives 25 times of flows on the one hand rushes at exhaust fume collecting hood, isolates oil smoke again, in order to avoid oil stain stains the inwall of exhaust fume collecting hood on the other hand in convergent-divergent channel exhaust fume collecting hood inner surface.
on put the operation principle of circular air knife:
1. convergent-divergent channel exhaust fume collecting hood.Convergent-divergent channel exhaust fume collecting hood is a kind of one large one small tubaeform pipe by Surface forming, and dehisce in order to collection oil smoke downwards for large one, little one upwards in order to discharge oil smoke.Inner surface smooth curve curvature is smooth, and sectional area reduces gradually, enables cooking fume against curved surface and has no to move upward with stopping, cooking fume can never be caused to rebound.Also because horizontal sectional area constantly shrinks, according to flow invariance principle, flue gas flow rate constantly increases, and the flow velocity that the velocity ratio convergent-divergent channel exhaust fume collecting hood that flue gas arrival horn mouth terminal and trunnion are just held just is held can increase 18-25 doubly.
