Abstract
A nanometer titanium dioxide photocatalyst air curtain range hood comprises a range hood main machine, wherein an outer exhaust fan is arranged in the range hood main machine, a smoke inlet and a smoke outlet are respectively arranged below and at the top end of the range hood main machine, and a smoke filter screen is arranged at the smoke inlet. The invention has the beneficial effects that: on one hand, a large amount of oil smoke mixed gas generated in the cooker and the pot is discharged outdoors, on the other hand, harmless gas purified by the air curtain machine meets the operator and forms an air curtain with gas generated on the pot surface, the air curtain forces the oil smoke generated on the cooker and the pot surface to be sucked by the main machine without overflowing, meanwhile, harmful gas generated on the pot stove is separated from air in the kitchen, and a large amount of pure air discharged by the air curtain machine is sucked by the operator, so that the operator is greatly protected and the suction effect of the main machine of the oil smoke machine is enhanced.
Description
Technical field
The present invention relates to fume exhauster for kitchen manufacturing technology field, specifically is a kind of nano titanium oxide photocatalyst air curtain range hood.
Technical background
The kitchen is huge numbers of families' Source of life; Also be the manufacturing source of people's environmental pollution simultaneously; A large amount of pernicious gases that produce when people cook and sewer, common duct, the food that rots, a large amount of germs, virus, foul odour that food waste produced distribute and waft and brim with between whole kitchen, greatly endanger people's health.General lampblack absorber manufacturer just simple increasing lampblack absorber discharge capacity solves the eliminating kitchen pollution, but can not reach comprehensive radical cure effect.
" circulation type cleaning oil smoke of band stereo air curtain " of prior art such as publication number CN1828148A; Its principal character is the method application photocatalyst of circulation in taking, the processing that activated carbon technology carries out the kitchen internal contamination; This purification method can have been alleviated kitchen pollution on certain degree; And practiced thrift building cost, reduced the trouble of installing.But Chinese have the cooking custom of quick-fried blast, and strong oil smoke still circulates in the kitchen through the suction residue flue gas of blower fan fast, is difficult to realize the purification fully of pernicious gas.Person in addition, a large amount of greasy dirts only depends on continuous replacing purifying net in the cigarette machine smoking process, has both increased the use cost of cigarette machine, again unusual trouble.
Other have patent No. ZL200820056278.0's " air curtain apparatus of side draught wind smoke exhaust "; This patent has been used the activated carbon filtration plate; Active carbon utilizes the porous physical characteristic to come big molecular gas and suspended particulate (for example smog, dust etc.) in the absorbed air, is the purpose that reaches the filtration, purification air through the blower fan forced-air circulation, but needs the periodic replacement filter core; Actual service efficiency is lower, can not eradicate pernicious gas.
Summary of the invention
The objective of the invention is deficiency, a kind of nano titanium oxide photocatalyst air curtain type range hood is provided according to prior art.The mode that this range hood adopts outer mist extractor to combine with the purification air in kitchen of internal-circulation type air curtain, and nano titanium oxide photocatalyst Purified core net is set in air curtain is more effectively discharged fume and is created hygienic conditions good in the kitchen with realization.
Technical scheme of the present invention is: a kind of nano titanium oxide photocatalyst air curtain range hood; Comprise the lampblack absorber main frame; Exhaust blower outside in this lampblack absorber main frame, being equipped with is respectively equipped with into mouth and exhaust opening with the top below this lampblack absorber main frame, advance mouth at this filtering oil smoke net is housed; It is characterized in that, nano titanium oxide photocatalyst air curtain is housed on this lampblack absorber main frame.
The invention has the beneficial effects as follows: air combined in exhausting type was aspirated oil smoke and interior circulation air curtain purifies the kitchen, and its good effect is following:
1, the cooking operation time spent opens simultaneously and effluxes suction type smoke machine host and interior circulation air curtain in the kitchen; The a large amount of oil smoke mists that produce in kitchen range and the pot are on the one hand discharged outdoor; Innocuous gas after air curtain purifies is met operating personnel and is formed air curtain with the gas that the pot face produces on the other hand; The oil smoke that air curtain had both forced stove and pot face to produce is sucked by main frame and not excessive; The pernicious gas that makes pot and stove produce is simultaneously separated with the kitchen room air, and what the operator head-on sucked is the air of the lot of pure of air curtain discharge, has greatly protected operating personnel and has strengthened the suction effect of lampblack absorber main frame.
2, the main air blower of range hood and air curtain are parallel circuit control, when kitchen operation finishes, can quit work the back and continue to open air curtain the operation of kitchen internal memory tail gas through air curtain obtained degree of depth circularly purifying at main frame, make air in kitchen more pure and fresh.
3, parallelly connected with control circuit fluorescent lamp has been realized the double effects that air cleaning and in-house operation throw light on, and has not only practiced thrift the energy but also made things convenient for operating personnel.
4, utilization nano titanium oxide photocatalyst makes that as catalyst good purification, air curtain fault rate are low, it is permanent to use, and does not need the frequent replacing filter screen of people.
Show after deliberation; The nano titanium oxide photocatalyst receives under natural daylight, the fluorescent lamp effect; Will produce electronics and the hole is right, hole and electronic energy combine with airborne water and oxygen respectively and produce hydroxyl free radical and the negative oxygen ion with extremely strong redox ability.Utilize this redox can decompose and remove airborne various organic substance and the inorganic pernicious gas of part effectively, sterilization, mildew-resistant, deodorize, the effect of environment purification such as antifouling.Photocatalyst is not participated in redox reaction directly as catalyst itself; And just change the required condition that takes place, so the ability of self not in time increase and be consumed and decay, in theory; Only otherwise painstakingly cross out or coat, photocatalyst can be for a long time effectively.
