Abstract

The utility model relates to a hood of oil soot extractor. The hood of oil soot extractor shrinks upwards and forms a circle opening from ambient wall to rectangle bottom, and the ambient wall forms a circle arc. The oil soot generated by earthenware pots raises by the shape. When the oil soot amount generated is larger than the oil soot discharged amount, and the excessive oil soot continuously flows and goes over across face. The excessive oil soot is leaded to flow back along the wall face by the circle arc-shaped ambient wall face and rotate cyclically. The excessive oil soot is sucked and discharged at last, which avoids the excessive oil soot escaping the hood of oil soot extractor.

Description

Hood of oil soot extactor

The utility model relates to a kind of improvement of range hood petticoat pipe.

Traditional range hood is to be used for and will to be gone into, be discharged by the oil smoke aspiration that frying pan broke out.But because of the oil smoke gas that suction and frying pan broke out of air draught bore and turbine box disproportionate, in the oil smoke amount of outburst during greater than air-breathing bore and turbine box suction amount, the oil smoke gas that moment can't suction in the way of rising to the external dissipation of range hood.The dealer has also done multiple design improved in this respect, attempts to improve this kind defective, to the oil smoke gas of desiring to run outward can't be pulled back exactly at present discharge again outdoor.

The purpose of this utility model is to provide the petticoat pipe of a novelty, the excessive oil flue gas of desiring outwards to run away can be guided, and is able to secondary and sucks, discharges.

According to a kind of smoke exhaust petticoat pipe of the present utility model, this petticoat pipe lower end is a rectangle, and the upper end is circular, it is characterized in that from the lower end oblong openings being the circular arc wall all around and toe-in between the upper rounded opening.

Above-mentioned feature of the present utility model makes and is subjected to the oil smoke gas that excessive desire is run outward the guiding of circular arc wall and confluxes into circulation revolution shape, imports discharge and be able to secondary.

With reference to the accompanying drawings, further specify the effect and the feature of the utility model.

Fig. 1 is the perspective view of the utility model.

Fig. 2 is the side view of the utility model.

Fig. 3 is the utility model view before.

Fig. 4 is the upward view of the utility model, to show its inside.

Fig. 5 shows oil smoke walking path side schematic view for the petticoat pipe that utilizes the utility model.

Fig. 6 shows oil smoke walking path front-view schematic diagram for the petticoat pipe that utilizes the utility model.

With reference to the petticoat pipe 1 of Fig. 1 and Fig. 4 the utility model, its lower end 101(covers on the gas burner frying pan top) be rectangle, upper end 102(is connected in the turbine box inlet scoop) rounded.Wall all around 103 by lower end 101 rectangle holes 102 circular ports to the upper end is circular arc, and the guiding oil smoke collects in the petticoat pipe.The oil smoke gas that this kind has the petticoat pipe of arc surface that desire is run outward is subjected to the guiding of circular arc wall 103 and is following circular arc wall revolution, and the suction of accepting is once more discharged.

The shape facility of the utility model can be promoted the smoking effect significantly.
