Abstract
A range hood with nanometer photocatalyst smell-removing and sterilizing air-purifying functions comprises a main box body and a panel covering the front opening of the main box body, wherein an air duct system is arranged in the main box body. The utility model has the advantages that: the nanometer titanium dioxide photocatalyst arranged inside the range hood can generate electron and hole pairs under the irradiation of natural light, a fluorescent lamp and an ultraviolet lamp, and the hole and the electron can be respectively combined with water and oxygen in the air to generate hydroxyl radicals and negative oxygen ions with extremely strong oxidation-reduction capability. The oxidation-reduction function can effectively decompose and remove various organic substances and partial inorganic harmful gases in the oil smoke, and has the functions of sterilizing, preventing mildew, deodorizing, preventing fouling and the like for purifying the environment.
Description
Technical field
The utility model relates to a kind of kitchen appliance, specifically a kind of range hood with nano photo-catalytic flavor-absorbing disinfecting air-cleaning function.
Background technology
Kitchen is huge numbers of families' Source of life, also be the manufacture source of people's environmental pollution simultaneously, a large amount of germs that a large amount of pernicious gas produced when people cook and sewer, common duct, the food rotted, food waste produce, virus, foul odour distribute and waft and brim with between whole kitchen, greatly endanger the health of people.The general lampblack absorber manufacturer just simple lampblack absorber discharge capacity that strengthens solves eliminating kitchen pollution, but can not reach and comprehensively effect a radical cure effect.
Prior art is as " circulation type cleaning oil smoke of band stereo air curtain " of publication number CN1828148A, its principal character be take the method application photocatalyst of Inner eycle, process that activated carbon technology carries out kitchen internal contamination, this purification method can alleviate kitchen pollution in certain degree, and saved building cost, decrease the trouble of installation.But Chinese have the cooking custom of quick-fried blast, strong oil smoke remains flue gas still at kitchen Inner eycle quickly through the suction of blower fan, is difficult to the purification completely realizing pernicious gas.Another person, greasy dirts a large amount of in cigarette machine smoking process, only by constantly changing purifying net, both having increased the use cost of cigarette machine, having bothered very much again.
Separately have " air curtain apparatus of side suction cooking fume exhauster air " of patent No. ZL200820056278.0, this patent employs activated carbon filtration plate, active carbon utilizes porous physical characteristic to come large molecular gas in absorbed air and suspended particulate such as smog, dust etc., it is the object being reached filtration, purification air by blower fan forced-air circulation, but need to regularly replace filter core, efficiency of actual is lower, can not eradicate pernicious gas.
Utility model content
The purpose of this utility model is the shortcoming existed to overcome prior art, and provide a kind of structure simple, easy to assembly, production cost is low, effectively can remove a kind of range hood with nano photo-catalytic flavor-absorbing disinfecting air-cleaning function of pernicious gas in oil smoke.
The utility model object realizes with the following methods: a kind of range hood with nano photo-catalytic flavor-absorbing disinfecting air-cleaning function, it panel comprising main box and cover its open front, panel is provided with smoking port, wind deflector entirety covers on smoking port, ducting system is provided with in main box, the air inlet of ducting system is coated with oil cleaner screen and communicates with smoking port, the air outlet of ducting system is connected with the exhaust opening being located at main box top, it is characterized in that: described main box inner surface, ducting system inner surface is provided with nano photo-catalytic coating, and in main box, be provided with more than one quartz burner irradiation nano photo-catalytic coating.
Described nano photo-catalytic coating is also arranged on oil cleaner screen surface.
Described quartz burner can be replaced fluorescent tube.
Described nano photo-catalytic coating is coating of titanium dioxide.
The beneficial effects of the utility model are: 1, structure is simple, and easy to assembly, production cost is low, improve the market competitiveness.2, the nano-titania photocatalyst being arranged on lampblack absorber inside is subject to natural daylight, fluorescent lamp, under the effect of ultraviolet lamps irradiates, will produce electronics and hole pair, hole and electronic energy combine with the water in air and oxygen respectively to produce and have hydroxyl free radical and the negative oxygen ion of extremely strong redox ability.Utilize this redox effectively to decompose and the various organic substance removed in oil smoke and part inorganic hazardous gas, sterilization, mildew-resistant, deodorize, the effect of the environment purification such as antifouling.3, photocatalyst does not participate in redox reaction directly as catalyst itself, and just change the required condition that occurs, so the ability of self not increase in time and be consumed and decay, in theory, only otherwise deliberately cross out or coat, photocatalyst can be effective for a long time, thus ensure its service life.
Accompanying drawing explanation
Fig. 1 is the utility model Standard figure.
Detailed description of the invention
Below in conjunction with accompanying drawing, concrete further instruction is done to the utility model.A kind of range hood with nano photo-catalytic flavor-absorbing disinfecting air-cleaning function, it panel 2 comprising main box 1 and cover its open front, panel 2 is provided with smoking port 3, wind deflector 4 entirety covers on smoking port 3, ducting system 5 is provided with in main box 1, the air inlet 51 of ducting system 5 is coated with oil cleaner screen 6 and communicates with smoking port 3, the air outlet 52 of ducting system 5 is connected with the exhaust opening 11 being located at main box 1 top, it is characterized in that: described main box 1 inner surface, ducting system 5 inner surface is provided with nano photo-catalytic coating, and in main box 1, be provided with more than one quartz burner 7 irradiate nano photo-catalytic coating.
Described nano photo-catalytic coating is also arranged on oil cleaner screen 6 surface.
Described quartz burner 7 can be replaced fluorescent tube.
Described nano photo-catalytic coating is coating of titanium dioxide.
Operation principle: when lampblack absorber works, position quartz burner in the inner or fluorescent tube work produce light and irradiate photocatalyst coating, photocatalyst coating will produce electronics and hole pair, and hole and electronic energy combine with the water in air and oxygen respectively to produce and have hydroxyl free radical and the negative oxygen ion of extremely strong redox ability.Utilize this redox effectively to decompose and the various organic substance removed in oil smoke and part inorganic hazardous gas, meanwhile, also there is sterilization, mildew-resistant, deodorize, the effect of the environment purification such as antifouling.Simultaneously, photocatalyst does not participate in redox reaction directly as catalyst itself, and just change the required condition that occurs, so the ability of self not increase in time and be consumed and decay, in theory, only otherwise deliberately cross out or coat, photocatalyst can be effective for a long time, thus ensure its service life, therefore can extensively promote the use of.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
