Abstract

The utility model relates to a solid body of an oil fume extractor with double outward tilting edges and a lamp hole, is one of the main components of an oil fume extractor, which comprises a cover plate A and a smoke-gathering hood B that is punched by a solid stainless steel plate. On the cover plate A, a notch 1 and rims 2 are provided, the outward tilt of the two rims is Phi is less than or equal to 70 degree; on the smoke-gathering hood B, a baseplate 3, a boss 4, a central hole 5, a lamp hole 7 and a turnup edge 6 with a tilt same with the rim 2 of the cover plate A are provided; then the smoke-gathering hood B is nested from the lower part of the cover plate A and welded with the cover plate A, still then buffing and polishing are carried out. The utility model removes the seam in the smoke-gathering hood of prior oil fume extractor and the seam in the circumference in the split structure of the cover board, so that the body becomes more sturdy and graceful, more rapid and fast to maintain and clean; and as the rims at two sides of the body tilt outward, the upper section of the smoke-gathering hood B integrated with the body is bigger than the lower section of the smoke-gathering hood B, when the oil fume is sucked, the speed at upper is higher than that at lower part, hence the extracting force of the oil fume extractor with such a body is increased.

Description

The bilateral flare lamp hole of range hood formula integral body

One, technical field

The utility model relates to a kind of fuselage of range hood, specifically the bilateral flare lamp hole of range hood formula integral body.

Two, background technology

At present, domestic range hood industry competition is more and more fierce, and competition focal point is a cost performance, and who can produce the best product of performance with the cost of minimum, and who just can establish oneself in an unassailable position forever.A few days ago, I am changed into the major part exhaust fume collecting hood of range hood the kitchen hood exhaust fume collecting hood (patent No. 02288029.1) of seamless monolithic construction by split-type structural, after using, find, though having, this exhaust fume collecting hood itself do not connect the scar weld seam, but when the fuselage of assembling range hood, still need place cover plate above it, therefore on the fuselage of range hood, leave the slit inevitably around the plane; Simultaneously, this exhaust fume collecting hood is not very good for the congregational rate of the oil smoke that culinary art produces yet, and cardinal symptom shows as the extracting force of oil smoke not enough.

Three, summary of the invention

The technical scheme of the bilateral flare lamp hole of the utility model range hood formula integral body technical issues that need to address and proposition is: remove on the fuselage of range hood the slit around the plane and increase the extracting force of range hood to oil smoke.Specific embodiments is: get two corrosion resistant plates, processing one breach, four edge breaks have frame (back frame is shorter, and approximate turns edge), the cover plate A that its bilateral frame leans outward on a corrosion resistant plate; On another corrosion resistant plate, strike out than cover plate A appearance and size smaller comprise base plate, boss, the hole, center, lamp hole, orifice plate (being used for fixing lamp) and four limits turn edge, and (it is higher afterwards to turn edge, and is similar to a frame, and it can process with exhaust fume collecting hood integral body, also can load onto separately), the exhaust fume collecting hood B that its bilateral turns edge and equates with the bilateral frame flare angle of cover plate A.Then exhaust fume collecting hood B is become one by packing into below the cover plate A, fill and lead up seam with argon arc welding again, use the polishing machine sanding and polishing.The fuselage of the range hood through being processed into has so just been eliminated it and has been gone up slit all around, plane, makes fuselage more solid attractive in appearance, the faster convenience of maintenance washes; And because the fuselage bilateral frame of this range hood leans outward, so its exhaust fume collecting hood B top section ratio lower section is little, so the flow velocity top of oil smoke when being sucked is bigger than the bottom, has promptly enlarged markedly the extracting force of range hood to oil smoke.

The technical scheme of the bilateral flare lamp hole of the utility model range hood formula integral body is: it comprises and has the cover plate A that breach 1 and four edge breaks have frame 2, than cover plate A appearance and size smaller comprise base plate 3, the turn edge exhaust fume collecting hood B of 6 grades of

boss

4,5, four limits, hole, center; It is characterized in that having a lamp hole 7 on the place ahead, base plate 3 at the hole, center 5 of exhaust fume collecting hood B, there is lamp plate 8 at lamp hole 7 one edges; The bilateral frame camber angle Φ of the frame 2 of cover plate A≤70 °; Four limits of the exhaust fume collecting hood B camber angle Φ that 6 bilateral turns edge that turns edge ₁Equate with the bilateral frame camber angle Φ of cover plate A.Then exhaust fume collecting hood B is become one by packing into below the cover plate A, fill and lead up seam with argon arc welding again, use the polishing machine sanding and polishing, make it to become the bilateral flare lamp hole of the utility model range hood formula integral body.Because this product is to shape the back socket respectively by two blocks of whole stainless steels, again through welding, sanding and polishing, be the full integral body that a kind of nothing connects the scar weld seam therefore, sump oil does not have the hiding-place; Because the bilateral frame of this fuselage leans outward, so its exhaust fume collecting hood B top section ratio lower section is little, so the flow velocity top of oil smoke when being sucked is bigger than the bottom, has promptly enlarged markedly the extracting force of range hood to oil smoke again.

Four, description of drawings

Fig. 1 is the bilateral flare lamp hole of the utility model range hood formula integral body decomposition chart and corresponding front view thereof.

Among the figure: A, cover plate; 1, breach; 2, frame.B, exhaust fume collecting hood; 3, base plate; 4, boss; 5, hole, center; 6, turn edge; 7, lamp hole; 8, lamp plate; Φ, Φ ₁, camber angle.

Fig. 1 illustrates:

The bilateral flare lamp hole of the utility model range hood formula integral body is an overall structure, and the exhaust fume collecting hood B that cover plate A that it is stamped to form by the monoblock corrosion resistant plate and monoblock corrosion resistant plate are stamped to form forms; On cover plate A, be processed with breach 1, frame 2, wherein bilateral frame camber angle Φ≤70 ° is processed with base plate 3 on the exhaust fume collecting hood B, boss 4, hole, center 5 turns edge 6, lamp hole 7, lamp plate 8, wherein the camber angle Φ that turns edge of bilateral ₁Equate (seeing cover plate A and the corresponding front view of exhaust fume collecting hood B) with the bilateral frame camber angle Φ of cover plate A.

Fig. 2 is the bilateral flare lamp hole of a utility model range hood formula integral body outline drawing.

Among the figure: A, cover plate; B, exhaust fume collecting hood.

Fig. 2 illustrates:

After cover plate A and exhaust fume collecting hood B shape respectively, exhaust fume collecting hood B is become one by packing into below the cover plate A, fill and lead up seam with argon arc welding again, use the polishing machine sanding and polishing, make it to become the bilateral flare lamp hole of the utility model range hood formula integral body.

Five, the specific embodiment:

At first, go out breach 1 and frame 2 in the punch press upper punch then, and make wherein bilateral frame camber angle Φ≤70 ° according to the development size of cover plate A monoblock stainless steel plate under shearing on the plate shearing machine; According to the development size of exhaust fume collecting hood B monoblock stainless steel plate under shearing on the plate shearing machine, on hydraulic press, suppress boss 4 then, after cutting edge, on punch press, go out hole, center 5, the lamp hole 7 of boss 4 again, lamp plate 8 and turn edge 6, and the camber angle Φ that bilateral is turned edge ₁Equate with the bilateral frame camber angle Φ of cover plate A.Again exhaust fume collecting hood B is packed into by cover plate A below and become one,, promptly become the bilateral flare lamp hole of the main part the utility model range hood formula integral body of range hood after welding, polishing, polishing.
