Description

Environment-friendly range hood
Technical field
The present invention relates to a kind of domestic oils fume treating device, relate in particular to a kind of environment-friendly range hood.
Background technology
Lampblack absorber has been come into huge numbers of families, has become popular consumer goods, and its major function is exactly to drain oil smoke and the waste gas that kitchen internal cause culinary art produces.At present, common lampblack absorber generally all is provided with air channel, blower fan, oil cleaner screen and catchment cup, and blower fan is discharged to wind in the air channel; Catchment cup is collected the greasy dirt that flows down from oil cleaner screen, after long-time the use, though there is catchment cup to exist; But in the air channel with can find all can the greasy dirt accumulation on the blower fan, deal with especially difficultly consuming time, and; Cause the blower fan load to increase, suction force descends; In addition, after oil cleaner screen and catchment cup are unloaded down, deal with also bothersome especially.
For this reason; A lot of rinsing type lampblack absorbers are disclosed in the prior art; Like the patent No. is Chinese utility model patent " cleaning the range hood automatically " (Granted publication number: CN2373711Y) of ZL99209588.3; This patent comprises the range hood main frame, it is characterized in that: the centrifugal blower of range hood is other to be provided with reservoir, and a scavenging pump is arranged in the reservoir; One end of woven hose is communicated with the delivery port of scavenging pump, the other end is communicated with spray head, and spray head is faced the impeller in the centrifugal fan and is fixed on the main frame.It similarly can also referenced patent number be Chinese utility model patent " smoke exhaust ventilator of automatic the cleaning " (Granted publication number: CN2566158Y) of ZL02272678.0.
How the water that produces in the above-mentioned patent lampblack absorber is handled, and does not provide concrete detailed answer, and reservoir is installed and comparatively inconvenience of replacing, needs to improve.
On this basis; There are a lot of improvement patents to occur again; Like the patent No. is Chinese invention patent " the smoke exhaust ventilator " (Granted publication number: CN100535530C) of ZL200610107966.0; To getting into the air heat exchange in the lampblack absorber and carry out water curtain type and clean then and discharged by exhausting duct, and water is realized circulation through a circulating pump; Can also referenced patent number be that (Granted publication number: CN201359311Y), this patent adopts atomizing type to combine filter gauze to collect oil droplet and purifies air for the Chinese utility model patent " a kind of comprehensive full-automatic range hood " of ZL200820145732.X.But above-mentioned patent is wanting in consideration owing to structural configuration; Make water and air hybrid density not enough, cause oil smoke washing poor effect, blower fan still need carry out irregular cleaning; And protective cover also need be set among the patent ZL200820145732.X in addition, will certainly increase manufacturing cost.
Summary of the invention
Technical problem to be solved by this invention is to the above-mentioned state of the art a kind of washing environment-friendly range hood completely to be provided.
Technical problem to be solved by this invention is to provide a kind of cooking fume-collecting complete to the above-mentioned state of the art, the environment-friendly range hood of convenient processing.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of environment-friendly range hood, comprise cabinet and blower fan, and aforesaid cabinet has air inlet, and aforementioned blower fan is located in the cabinet and over against air inlet, it is characterized in that this lampblack absorber also comprises
Water tank, detachable are located at the cabinet bottom and can be collected the liquid that flows down from said cabinet inwall;
Water pump is used in aforesaid water tank, drawing water;
Shower nozzle is located on the described blower fan;
Water pipe, water inlet end is connected with the water side of aforementioned water pump, and the water side is connected with the water inlet end of aforementioned shower nozzle; And
Backwind tube joins with the air outlet of said blower fan.
Described shower nozzle is at least two, and around described blower fan setting.Be beneficial to the formation moisture film.
Described blower fan comprises motor and by motor-driven fan, the connecting portion in the middle of this fan comprises reaches around the radial blade part of connecting portion, and described shower nozzle is located at the inner end of aforementioned blade part also from outer inside the injection.Described shower nozzle also can be to be located on the aforementioned connecting portion.
Be provided with an electric heating tube in the described water tank.Add hot water, improve atomizing effect, help the clean cigarette of oil suction.
The air outlet of said backwind tube stretch into be discharged into after the washing of described water tank indoor.After the washing, make the air discharged compliance with environmental protection requirements once more, so just need not on wall, to be provided with air exhaust passage.
Described backwind tube passes through an air-flow reducing transformer before stretching into water tank, is used to relax air pressure.
Compared with prior art, the invention has the advantages that: starting mode of pump is extracted into water in the water pipe and from shower nozzle in the water tank and gushes out, through the centrifugal action of blower fan; Around blower fan, form the moisture film of one deck column rotation, the oil smoke that sucks in is directly contacted with moisture film is positive, and oil smoke is rotated water washing cleaning; Water body flows in the water tank along the cabinet inwall then, recycles, and comes out from backwind tube through the air that purifies simultaneously; In the whole process, oil smoke does not directly contact with blower fan, can not accumulate greasy dirt on the blower fan; Very most greasy dirt and flue dust all flow to through washing and obtain in the water tank collecting, and get final product and regularly water tank is changed water treatment.Overall structure is simple, and oil smoke is handled with washing, and purifying rate is high, is not discharged in the atmosphere environmentally-friendly sanitary.
