As shown in Figure 4, another kind of known double-fan structure with diaphragm, mutually butt welding is formed by two " δ " type wind stomach C, on the body of this " δ " type wind stomach C, respectively offer inlet scoop C2, and make the C1 of its smoke evacuation portion be streamlined radian and bottom surface forming the cambered surface of water conservancy diversion smoothly, the arc edge of " δ " type front end of its mat two wind stomaches also sets firmly and forms a double-fan with diaphragm by spot welding, though this kind structural design has preferable water conservancy diversion effect than the former the wind stomach of known partition deflector structure, but it closes admittedly only according to the base point solder joint on the arc edge of front end, so suitable fragility of its intensity, and two wind stomaches in and close in the welding process very easily that deflection walks, make the centre-to-centre spacing of two wind stomaches produce error, therefore when assembly, fan and the dried mutually problem that can't turn round of establishing of wind stomach take place.

Based on this, the inventor germinates the meaning of improvement, through constantly studying, testing, develop the utility model eventually, its purpose is at the structure-improved that a kind of double-fan partition deflector is provided, and two partition deflectors in the wind stomach manufactured and designed with economic way form, and obtains best firm effect when making it in being installed in the wind stomach, and also become consistent streamline form with the smoking of wind stomach, so that the oil smoke discharge effect is more efficient with two exhaust smoke holes.

The purpose of this utility model is achieved in that a kind of structure-improved of double-fan partition deflector, this partition deflector body is set as symmetrical two groups, it is characterized in that each group partition deflector all is formed with a base plate, this base plate forms the continuous bend form, and has an arc end, side in this arc end forms a straight flange with all lines, and the other end in nose circle forms a curve arc limit with a tangential, in this arc end, straight flange and arc limit have all upwards extended wooden partition, the wooden partition lateral surface that the arc end of two partition deflector bodies is opposite to its arc limit is welded in the inwall of wind stomach, the exhaust opening of wind stomach just with this base plate formation streamline form.

The utility model is when being assemblied in the wind stomach with partition deflector body, with the arc end of two partition deflector bodies opposite one another in the wooden partition outside on its arc limit, and with in its cover inlet air stomach the time, its arc limit is cut be affixed on wind stomach 2 inboard preformed long limits, straight flange is then cut and is affixed on the inboard minor face that forms earlier that gives of wind stomach, and the wooden partition medial surface that this straight flange and arc side weld is fixed in the wind stomach by spot welding is with fixing, the exhaust opening that makes the wind stomach just forms streamline form and must be in the discharge of oil smoke in this base plate, the cunning of oil smoke flow path is along state by this, the noise that it can not be created in, and air loss also can reduce, and structure is firm, and smoke discharging effect is good.

Partition deflector body of the present utility model during fabrication, have identical two groups by special mould is integrally formed, and wherein a right-angle side of a partition water conservancy diversion body is connected with the arc limit of another partition deflector body, two groups of bodies are blocked in its right-angle side and the joint on arc limit can be assemblied in the wind stomach according to above-mentioned method combination, use and simplify overall structure and reduce production costs, more rationalization.
