Technical scheme of the present invention is achieved in that clarifying oil soot exhauster, it mainly comprises the range hood shell, top cover, be contained in the dividing plate in the range hood shell, blower fan and import and export with matching, be provided with separator-filter in import, it is characterized in that: the passage 3 that broad is arranged between range hood shell and separator-filter housing, the passage 5 that broad is also arranged between separator-filter housing and dividing plate: in separator-filter, be provided with baffle plate and inner core, filtering net box 9 is set under inner core, in the filtering net box 9 filtering bodies is housed, between separator-filter housing and inner core, form slit, in the separator-filter housing, be marked with the medium of better absorption property.

The present invention compared with prior art has following characteristics:

1, flue gas is guaranteed the blower fan oily dirt free, is exempted to unpick and wash through separating, filtering thoroughly oil removing;

2, can directly arrange indoor through separation, filtration, flue gas after being purified, prevent to pollute removal of home, help protecting environment, and can accomplish not burrow on the wall, indoor no pipeline, easy for installation, help protecting the attractive in appearance of building, also can use in the place that inconvenience burrows, enlarge the range of application of range hood;

3, shell separator has bigger capacity, and waste oil can be cleared up once in 1 year, and is easy to use, and do not have oil leakage phenomenon;

4, noise is lower, has prolonged the service life of motor, and filtration, scavenging material life-span were more than 1 year, did not need frequent replacing;

5, both can make row in the flue gas, also can efflux easy switching.

Fig. 1 is a structural representation of the present invention

The invention will be further described below in conjunction with drawings and Examples

The present invention mainly comprises range hood shell 1, top cover 12, be contained in the dividing plate 4 in the range hood shell 1, blower fan 18 and the import and export that match with them, be provided with separator-filter 19 in import department, it is different from prior art: 2 of range hood shell 1 and separator-filter housings have the passage 3 of broad, 4 on separator-filter housing 2 and dividing plate also have the passage 5 of broad, in separator-filter 19, be provided with baffle plate 8 and inner core 6, below inner core 6, be provided with filtering net box 9, in filtering net box 9, filtering bodies is housed, filtering bodies generally adopts screen pack or filter paper, form slit 7 at separator-filter housing 2 and 6 of inner cores, in separator-filter housing 2, be marked with medium 21 with better absorption property, this medium can be water or liquid, also can be that other has adsorbing medium, in an embodiment in order to increase the adsorption effect of oil smoke, passage 3 and slit outlet all are several times as much as slit 7 with the distance of medium face and the distance of baffle plate 8 and inner core 6: same in order to strengthen the filter effect of flue gas, filtering bodies vertical section in the filtering net box is corrugated: the blower fan 18 that is contained in the range hood shell is provided with two outlets 20, on the range hood shell, also be provided with two purifying net boxes 11 that match with the blower fan outlet, purifying net in the purifying net box 11 also forms corrugated, purify area to increase, reduce resistance, prolong the service life of purifying net, supporting the net holder of purifying net is made by the polypropylene with sterilizing function, purifying net box 11 inserts in range hood top cover 12 vallecular cavities from top to bottom, rely on several elastic supports 15 in the vallecular cavity outside, purifying net box 11 is pressed on the plane of vallecular cavity inboard, and making its sealing and fixing, this structure makes the dismounting of purifying net box very convenient; Outlet 22 places at range hood are provided with gland 14, be covered with the hole on gland 14, purifying net 16 is housed in gland, its effect is partial fume to be purified from this back warp discharge, make the blower motor surface that certain cooling flow be arranged, also be lined with the plastic foamboard 17 of perforate in range hood shell inboard; Respectively be embedded with the cover plate 13 of a perforate in top cover 12 both sides of range hood, by interior circulation (interior row) outlet as flue gas when mode is moved, as moving by the mode of effluxing, then available gummed paper is blocked perforate, and cracking-off gland 14, connect outlet at outlet 22 places of range hood and get final product.
