Abstract
The device belongs to a smoke removing device, in particular to a self-purification range hood adopting multi-layer filtration. The device is provided with a fan, a filtering structural part, a spraying cleaning part, a control circuit and a box body. Because of adopting the design of the multilayer filtering structure of the oil collecting net, the filtering net and the activated carbon net, the oil-smoke extractor can effectively filter harmful components in the oil-smoke gas and does not discharge polluted gas outdoors. In addition, due to the arrangement of the spraying cleaning component, when the range hood is started or closed, the spraying system can automatically spray and clean the filter screen. The range hood can also be cleaned by manually controlling the spraying system to keep the range hood in a good working state, and harmful oil smoke components are decomposed into pollution-free or low-pollution liquid under the action of the cleaning liquid, so that the air pollution caused by the oil smoke is obviously reduced from the source, and the purpose of self-purification is achieved. Meanwhile, the use can be carried out without perforating through the wall.
Description
(1) technical field
The utility model belongs to a kind of remover apparatus of flue gas, especially a kind of range hood that adopts multiple filtration.
(2) background technology
Though smoke exhaust has many styles on the market at present, their operation principle all is: the suction that utilizes blower fan (motor) wheel rotation to produce flows air, and then contaminated gas is directly discharged outdoor, reduces indoor air pollution.But such duty only shifts pollution sources, fundamentally not harmful gas clean-up.A kind of filtering type range hood of CN2122316U patent disclosure, it is provided with shell, motor and is fixed on wind wheel on the outer rotor, and there is the wind wheel over cap outer ring of wind wheel, and the filter screen of convenient mounting or dismounting is housed on the machine shell of the outside of wind wheel.A kind of range hood of CN2137337Y patent disclosure, have body, medium frame plate and bellows that bispin fan blade suction motor and casing constitute, extend to its root edge from the back segment of medium frame plate and be provided with the 3rd suction port assembly, this device carries a slice lengthy motion picture shape oil cleaner screen by a horizontal shape suction inlet and one or more lubricating cup is constituted, and a said horizontal shape suction inlet and a pair that makes tapered hole are led smoke guiding hole and become one; Bellows are by air draft case (female case) and lead smoke-box (sub-case) and constituted, and lead the suction inlet of the air admission hole of smoke-box facing to the medium frame plate root edge.
(3) summary of the invention
The purpose of this utility model is to provide a kind of improved range hood, and it can filter out discharging again behind the composition harmful, that flavor is arranged to soot gas, thereby reaches effectively harmful components in the filtering soot gas, the purpose that purifies air.
The utility model is provided with blower fan, is made up of motor and at least 1 rotary impeller; Filtration spare is made up of at least 1 layer of oil-collecting net, 1 layer of screen pack and active carbon net and oil collector at least, and oil-collecting net, screen pack and active carbon net form layered structure, and is located in the main air duct in the casing; The spray Cleaning for High Capacity parts are made up of at least 1 spray head and liquid container, liquid pump; Spray head is located on the liquid pump, and liquid pump, spray head and liquid container are located at the below of filtration spare.Control circuit is used to control blower fan, liquid pump, illuminating lamp and switch; Casing, be used for containing, supporting above-mentioned blower fan, filtration spare, spray Cleaning for High Capacity parts and control circuit, and be combined into complete machine, on casing, be provided with air inlet, gas outlet, feed liquor cup, illuminating lamp, hanger etc., air inlet is positioned at the below of air channel and filtration spare, and the gas outlet is positioned at the top of air channel and filtration spare.
Said rotary impeller can be located at the top or the bottom in air channel in the casing, can adopt list/pair blower fan rotary impeller or blower fan to be located at filtration spare rear portion.
In the said filtration spare, the oil-collecting net is positioned at lower floor, and active carbon net is positioned at the upper strata, and screen pack is between oil-collecting net and active carbon net.Also can adopt multilayer to intersect repeatedly puts.Can adopt the different holes of multilayer purpose filter screen.Can be gapped between each net.But each net full wafer design or multi-disc splicing.Said spray Cleaning for High Capacity parts can adopt shower nozzle to spray form or the shower form is cleaned filtration spare.When range hood is worked, the oil smoke air will be inhaled into from air inlet and enter the air channel, and filter greasy dirt and part peculiar smell by multilayer oil-collecting net, screen pack, be fallen remaining peculiar smell by charcoal absorption in the gas outlet, at last outside gas outlet discharging outlet.
Because the utility model adopts oil-collecting net, screen pack, active carbon net multiple filtration structural design, therefore can be in range hood inside harmful components in the filtering soot gas effectively, to the outdoor gas that does not discharge pollution.In addition, owing to be provided with the spray Cleaning for High Capacity parts, when starting or closing range hood, spray system all can be carried out automatic spray to filter screen and be cleaned.Also can adopt the Artificial Control spray system to carry out spray Cleaning for High Capacity, make range hood keep good working order, make harmful oil smoke composition under the effect of cleaning fluid, resolve into pollution-free or oligosaprobic liquid simultaneously, reduce the air pollution that causes because of oil smoke significantly from the source, reach the auto purification purpose.Simultaneously, can through wallsly burrow tubing during use.
