Description
Technical field
The present invention relates to kitchen appliance, be specially a kind of range hood.
Background technology
Take PM2.5 as the haze of mark, arrived the condition allowing compatriots turn pale at the mention of the tiger, atmosphere pollution also more and more becomes the much-talked-about topic that the common people pay close attention to.But, the haze in atmospheric environment is apparent, kitchen fume to the contribution of haze but ignore by the public.The research that the Wang Yuesi of Chinese Academy of Sciences's atmospheric physics institute carried out in 2012 finds, summer in 2012, the PM2.5 particulate pollutant of heart of Beijing has 15% to 20% from kitchen exhaust gas.This makes kitchen exhaust gas become continue Vehicular exhaust with from the third-largest air pollution source after the pollutant wafted in surrounding area." cooking fume discharge standard " specifies, the highest permission concentration of emission is 2.0mg/m3.Experimental result finds, various cooking method substantially all exceedes the highest permission concentration of emission, wherein fried fish concentration of emission is 25.5mg/m3. China total population 1,300,000,000 at present, calculate with average each family 4.5 people, about You2.9Yi Ge family, every lampblack absorber exhaust air rate is about 15m3/min (have part family to be by simple ventilating fan or directly enter in air), concentration of emission is 5.0mg/m3, full-time employment calculates for 2 hours, about has 26100 tons/day at the end of the day, 9396000 tons/year.
Through the investigation to existing lampblack absorber market, no matter be the common smoke exhaust ventilator of 400-500 unit or the high-grade lampblack absorber of 5000-6000 unit, be all simply oil smoke is extracted out outdoor, just oil smoke in lampblack absorber under condensation about 40% grease and flue dust, and initiatively cooking fume is not processed, so there is no play good catharsis.So we often can smell the pepper flavor of various fragrance or even the people that chokes at cooking time.And smoke exhaust ventilator is long for service time one at present, a large amount of putty can be gathered in inside, thus makes smoke exhaust ventilator exhausting deleterious, and noise becomes large but also power consumption strengthens, and service life shortens; The a large amount of putties gathered in addition are difficult to cleaning, bring a very large cleaning difficult problem to user.
" cooking fume discharge standard " specifies, the highest permission concentration of emission is 2.0mg/m3.Not at outdoor mounted exhaust gas purification apparatus, discharge substandard restaurant and will be prohibited to do business.The exhaust gas purification apparatus cost used at present due to catering trade is high, volume is large, trouble is installed, maintaining difficulty, make the many employings of oil smoke of middle-size and small-size food and drink numerous at present in line enter the mode of air, progress due to broad masses of the people's environmental consciousness makes the complaint of this respect in recent years roll up, and some places prohibit barbecue especially.
More have expert to point out: the PM2.5 that kitchen fume produces far will be far more than haze, harmful substance contained in kitchen fume reaches kind more than 300, is more than 15 times of haze, wherein also containing multiple noxious material that can be carcinogenic.
A kind of cost can be designed not high, easy for installation, the smoke exhaust ventilator that fume eliminating is effective? in view of current industrial electrostatic smoke abatement technology is very ripe, applicant has application " a kind of novel kitchen smoke exhaust ventilator " (application number is 201520227462.7) that high-voltage static flue gas removing device is directly installed on inside lampblack absorber on April 16th, 2015.But find in actual use that a large amount of oil smoke concentrates interception on high-voltage static flue gas removing battery lead plate, do not solve the clean of original patented product and this large problem of maintaining, former patent actual application value can be caused not high.Therefore, inventor carries out a large amount of experiment repeatedly on the basis of this patent, has paid a large amount of creative works and has improved.
