Abstract

The utility model relates to a bilateral extroversion fenestration integrated machine body of exhaust hood, which is one of the main spare parts of the exhaust hood. The machine body comprises a cover plate A that is made by stamping a whole stainless steel plate and a smoke-collecting helmet B. A gap 1, a window 3 and a frame 2 are all positioned on the cover plate A; a bilateral frames extroversion angle of smaller than or equal to 70 degree are processed and arranged on the cover plate A. A Base plate 4, a flange 5, a center hole 6 and a turned edge with the same extroversion angle as that of the frame 2 are processed and arranged in the smoke-collecting helmet B. After the smoke-collecting helmet is set inside from the bottom of the cover plate A, the smoke-collecting helmet is then welded, grinded and polished, the integrated machine body is completed. The integrated machine body eliminates the gaps around the machine body that is made by the assembling of the smoke-collecting cover and the cover plate, thereby, the machine body becomes more compact and beautiful and the maintenance and cleaning also become much faster and more convenient. Resulting from that the bilateral frames are extroverting, the upper cross section of the smoke-collecting cover B as a whole body with the machine body is smaller than that of the bottom part, and when in releasing, the flow rate of the upper part of the exhaust hood is faster than that of the bottom, thereby improving the releasing strength of the exhaust hood to the exhaust hood of the configured machine body.

Description

The bilateral flare fenestration of range hood integral body

One, technical field

The utility model relates to a kind of fuselage of range hood, specifically the bilateral flare fenestration of range hood 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 assemble a cover plate above it, therefore around the fuselage edge of range hood, leave the slit inevitably, not only influenced attractive in appearancely, brought inconvenience also for usual cleaning maintenance.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 fenestration of the utility model range hood integral body technical issues that need to address and proposition is: the slit all around, fuselage edge of removing range hood, make complete machine more attractive in appearance, more firm, maintenance washes is also more convenient, and increases the extracting force of range hood to oil smoke.Specific embodiments is: get two corrosion resistant plates, processing one breach on a corrosion resistant plate, the place ahead of breach are opened a window (have the window lid, can be convenient to the maintenance to switch), all around folding has frame (back frame approximate turns edge), the cover plate that the bilateral frame leans outward; On another corrosion resistant plate, strike out than cover plate appearance and size smaller comprise base plate, boss, hole, center, all around turn edge, its bilateral turns edge and equates the exhaust fume collecting hood of (the approximate frame that afterwards turns edge, it can process with exhaust fume collecting hood integral body, also can load onto separately) with the bilateral frame flare angle of cover plate.Then exhaust fume collecting hood is become one by packing into below the cover plate, fill and lead up slit all around, fuselage edge with argon arc welding again, use the polishing machine sanding and polishing.The integral body of the range hood through being processed into like this is more solid more attractive in appearance than original fuselage, the also faster convenience of maintenance washes.And because the fuselage bilateral frame of this range hood leans outward, so its exhaust fume collecting hood 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 fenestration of the utility model range hood integral body is: it comprise have breach 1 and all around folding the cover plate A of frame 2 is arranged, than cover plate A appearance and size smaller comprise base plate 4, boss 5, hole, center 6, all around folding has the exhaust fume collecting hood B of 7 grades that turn edge; The place ahead that it is characterized in that the breach 1 of cover plate A has the window 3 of band window lid, all around the bilateral frame camber angle Φ of frame 2≤70 °; The bilateral of the exhaust fume collecting hood B camber angle Φ 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 slit all around, fuselage edge with argon arc welding again, use the polishing machine sanding and polishing.Make it to become the bilateral flare fenestration of the utility model range hood 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 integral body that a kind of nothing connects the scar weld seam therefore, sump oil does not have the hiding-place; Again 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, promptly enlarged markedly the range hood that disposes this fuselage extracting force to oil smoke.

Four, description of drawings

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

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

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

Fig. 1, Fig. 2 illustrate:

The bilateral flare window-opening integral frame of oil-smoke Wei of the utility model fume-exhausting machine Yi Zheng body structure, its You Zheng piece is not The cover plate A that the Xiu steel plate punched forms becomes with the exhaust fume collecting hood B Zu that Zheng piece corrosion resistant plate is stamped to form; Zai cover plate A On be processed with breach 1, frame 2, bilateral frame camber angle Φ≤70 ° wherein, window 3 (is with fenestrate Lid); Be processed with base plate 4 on the exhaust fume collecting hood B, boss 5, Zhong Xin hole 6 turns edge 7, and wherein bilateral turns edge Camber angle Φ₁Yu (seeing the corresponding Zhu view of Fig. 1) such as the bilateral frame camber angle Φ of cover plate A Xiang.

Five, the specific embodiment:

At first, on punch press, stamp out breach 1, window 3 (being with window lid) and frame 2 then, and make wherein bilateral frame camber angle Φ≤70 ° according to cover plate A development size 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 (5) then, after cutting edge, on punch press, go out the hole, center (6) of boss (5) and turn edge (7) again, and make the bilateral camber angle Φ that turns edge ₁Φ equates with cover plate A bilateral frame camber angle.Again exhaust fume collecting hood B is packed into by cover plate A below and become one,, promptly become the bilateral flare fenestration of the main part the utility model range hood integral body of range hood after welding, polishing, polishing.
